EP1318255B1 - Actuation device for a locking device of a door or tail-gate etc. in particular for a vehicle - Google Patents

Description

The invention is directed to a device specified in the preamble of claim 1. Art. These are applied to outside door handles with electronic control of code interrogation systems. If the outside door handle is pulled, then the electrical switch is actuated, thereby generating a carrier signal. This signal causes the locking system to start the access authorization procedure.

In a door lock for motor vehicles ( DE 199 47 483 A1 ) is an actuating element is known, which has position elements along staggered trajectories. Each trajectory is assigned a sensor with which each setting position can be clearly detected. For this purpose, however, it is necessary to arrange empty intermediate areas between the areas of the actuating element which characterize the setting positions. The actuator is namely driven by a motor which has a tail after its shutdown. The caster is due to the inertial forces in the system. This motor is turned off when the limit of such an intermediate range to the desired setting position is exceeded. Then the actuator remains in that field where the assigned sensors on the coded position elements can read the correct position. To be functional, the known door lock can not do without this intermediate area. However, these intermediate areas are space-consuming and reduce the payload fields for the arrangement of the code-generating position elements on the actuating element.

In another device ( EP 0 218 251 A1 ) It is known to assign a handle two different switches that trigger different functions. The first switch takes effect when you pull the handle in one direction. The other switch works by operating the handle in the opposite direction. The arrangement of two switches is space and material consuming. Above all, however, tolerance problems arise. The door handle must take a certain position in its rest position, which is not always possible, especially after prolonged use. It can lead to incorrect switching, if the outside door handle is not returned to its final rest position after its operation. The installation tolerances are very tight, which causes great expense in the production and assembly.

In a door handle, it is known ( DE 196 42 698 C2 ) to provide a rack on the handle. On the support of this handle a gear is mounted, in which engages the rack. The toothed wheel has a stop edge in order to cooperate with an electromagnetically operable locking bolt via a two-armed, also pivotally mounted on the carrier two-armed lever. Normally, a pressure switch is arranged next to the door handle, after the actuation of the locking bolt is removed. As a result, the pivot lever will release the gear. The gear is also part of an emergency operation, which counts a connected to the door lock Bowden cable. After a collision accident, a sensor responds which deactivates the locking bolt. If now pulled on the door handle, so the gear is rotated by the rack and the lever is pivoted against the action of a spring until one end to a shoulder in the carrier comes to rest. The lock is mechanically opened via the Bowden cable. Codings are not provided here.

The invention has for its object to develop a reliable device referred to in the preamble of claim 1 species, which is designed to save space. This is inventively achieved by the measures specified in claim 1, which have the following special significance.

The evaluator not only responds to a change in the code signals, but determines the order of the incoming code signals. From this, the evaluator can clearly recognize the sense of direction of the handle operation, without the need for additional components are required. When the handle operation in one direction, a first function is triggered and upon actuation of the handle in the opposite direction, a second function. The first function can start the expiry of an access authorization to the vehicle. The second function may be to deactivate the conditional access system again.

Further measures and advantages of the invention will become apparent from the other dependent claims, the following description and the drawings. In the drawings, the invention is shown schematically in an embodiment. Show it:

Detailed views of a in a rotary switch of the device of Fig. 1 integrated rotor in four different rotational positions.

The device comprises a handle 10, which is pivotally mounted in a stationary carrier 20 at the point marked 11. In this case, it is a pull handle with a pivot axis extending substantially vertically in the vehicle door. But it could also be a folding handle, where the pivot axis is substantially horizontal. Finally, for the application of the invention, combinations of both types of handles are possible, where the pivot axis an inclined course in the vehicle door occupies. The carrier 20 is attached to the inside of a door outer panel 21 and has a recessed grip 22. In the support region, at least one opening 23 is provided, through which the handle 10 projects with its two handle ends. The one end of the handle extends at an angle and is a bearing end 12, which has the mentioned pivot bearing 11. The other end of the grip is provided with a projection 13 which engages behind a first member 15 of a mechanical locking system with a protruding finger 14.

In the carrier 20, a lock cylinder 24 may be integrated, which belongs to a so-called cylinder tower 25. The cylinder tower 25 expediently extends the schauseitigen handle profile in the region of the neck 13 bearing end of the handle. At the handle 10 at least indirectly resort to spring return means, which endeavor to the handle in the in Fig. 1 to keep drawn drawn rest position, the course is illustrated by the auxiliary line 10.1.

If the handle 10 is grasped and pulled by a human hand, it executes the movement illustrated by the pivot arrow 16 and reaches the dot-dash line in FIG Fig. 1 illustrated work situation. This work situation is in Fig. 1 marked by an auxiliary line 10.2. In the working position 10.2, the member 15 is taken from the locking system and enters the dash-dotted in Fig. 1 illustrated actuating position 15 '. In the operating position 15 ', however, the door can only be opened when the locking system is set effectively and is in its unlocked position. But if the secure position of the locking system is present, then the locking system is ineffective; the aforementioned handle 16 then does not affect the locking system. The door remains locked.

The reversal of the locking system between its effective and inoperative position is determined by an access authorization, which may be formed in various ways known per se, eg mechanically and / or electrically. A legitimate position has the associated access authorization means, for example in the form of a code card that activates the electronics of the vehicle when approaching the vehicle via a code question and answer system, but initially does not trigger reversal of the locking system between its secured and unsecured position. This reversal of the locking system comes only then if the authorized person carries out a specific further action in the area of the device.

This action in the present case is simply that the authorized person begins to operate the handle 10. In this case, the initial phase of the pivoting movement 16 is used even before the first member 15 of the locking system is taken along in a relevant manner. Until then, the aforementioned reversal between the two positions is possible.

In approach 13 of the handle 10, an electrical rotary switch 30 is integrated, in which a in Fig. 2 seen in plan view rotor 31 is located. This rotor 31 is rotatably connected via a shaft 26 with a pinion 27. The circumferential toothing of the pinion 27 is engaged with a rack 20 seated on the carrier 20. Already the initial phase of the pivotal movement 16 leads to a relevant rotation 32 of the rotor, which changes a pulse signal to be described in more detail, which is forwarded via signal lines 18 to an evaluator 28 becomes. This evaluator 28 is arranged in the present case in the handle interior, where there are already electrical components for other functions; eg capacitive sensors for the motorized operation of the locking system. From the evaluator 28 go from control lines 29, which continue on a arranged at the handle end two-piece electrical coupling 39 to the desired electronic actuators in the vehicle. These actuators act on the locking system in an electrical and / or mechanical manner and / or bring about further functions in the vehicle, such as the switching on and off of the alarm system. Inside the handle also runs a supply line 19 for the rotary switch 30. These lines 18, 19 can be mitverlegt readily with the other mentioned inside the handle control lines. The power supply of the rotary switch 30 therefore requires no additional line course and space. The rotary switch 30 is an integral part of the handle 10 and therefore well protected there.

The Fig. 2 to 5 show an example of how the pulse signals detected by the evaluator 28 can come about. In this embodiment, an electrical input 43 is connected to a wiper 40, which is arranged at a small radial distance 36 away from the shaft 26. The input line 43 is in Fig. 2 indicated by dash-dotted lines. To the input line 43, the aforementioned supply line 19 is connected.

The rotary switch 30 has at its rotor 31, two more grinders 41, 42, which are arranged at two outputs 44, 45 of the rotary switch. These output lines 44, 45 are in Fig. 2 also illustrated in phantom and connected via the already mentioned signal lines 18 to the evaluator 28. While one grinder 41 is arranged at a large radial distance 37 from the shaft 26, the other grinder 42 occupies a mean distance 38.

In the three zones of the three grinders 40 to 42 angularly differently sized current-conducting and current non-conductive segments 33, 34 are arranged on the rotor 31. The current-conducting segments 33 are in the Fig. 2 to 5 emphasized by dot hatching, while the electrically non-conductive segments 34 are shown smooth. Which zone of the segments 33, 34 are present in the grinders 40 to 42 depends once on the segment length, but also on the three different zones determining different distances 36 to 38 and their angular position to each other. In the application according to the embodiment of Fig. 2 to 5 the following pulse signals are determined in the four different rotational positions of the switch.

In a first rotational position of the switch 30, which is illustrated by an auxiliary line 35.1, the rotor 31 takes out the Fig. 2 apparent position. In the radial distance 36, the current-conducting, highlighted by dot-hatching segment 33 is formed as a full circle, which is why not only in this first rotational position 35.1, but also in all other 35.2 to 35.4 always a voltage applied to the segment 33. At the electrical outputs 44, 45, however, a very different segment profile is present in the four rotational positions. In the first rotational position 35.1 of Fig. 2 Both wiper 41, 42 with the non-conductive segment 34 in contact, which is why at the associated outputs 44, 45, the pulse signal "0-0" is obtained.

In the second rotational position 35.2 of Fig. 3 The first grinder 41 is acted upon by the voltage of the input grinder 40, while the second grinder 42 is tensionless. Therefore lies in this second rotational position 35.2 of Fig. 3 the pulse signal "01" before.

If the rotor 31 by another quarter circle to the rotational position of 35.3 of Fig. 4 has been moved, so are opposite Fig. 3 the reverse voltage conditions on the two output slides 41, 42 before. Now the pulse signal "1-0" results. Finally, at the further rotation in the fourth position 35.4 of Fig. 5 the outputs of both grinders 41, 42 have voltage. In this case, so the pulse signal "1-1" is present.

Thus, the evaluator 28 receives distinctly different pulse signals via the signal lines 18 as a function of the four rotational positions 35.1 to 35.4, which is why it can clearly distinguish whether the grip is in the first, second, third or last phase of its 4-fold articulated movement , Each phase here covers exactly a quarter-circle angle and not just a switching point. It is understood that by other dimensioning of the segment profiles 33, 34, the change in the pulse signals at any other angle ranges of the rotary switch 30 and thus at mutually different phases of the handle 16 operation could take place. This depends on the desired reversal of the locking system.

It is believed that in the rest position 10.1 of Fig. 1 the locking system is in its inoperative position, that is secured. As can be seen from the size of the segments, it does not depend on an exact rest position 10.1; The handle can readily take deviations from this ideal position without the pulse signal "0-0" changes. This changes in the present case only in the rotational position 35.2 of Fig. 3 What allows a game of rest position of the handle 10. For a further rotation to 35.3 according to Fig. 4 the evaluator would already diagnose a second change in the pulse signals. At the latest then reports the evaluator 28 a clear movement of the handle on the aforementioned control lines 29 the relevant control units in the vehicle. Then the locking system is set effectively; it is unlocked. If then, because in the further movement 16 of the handle 10, the working position 10.2 is reached, the locking system is already in effect and in his operating position 15 'come first member of the locking system releases the door. The door can be opened.

Starting from a rest position 10.1, the handle, which is not shown in detail, could also be brought into a position opposite to 10.2, for example, in one of the said pulling operation 16 of the handle 10 opposite pressure actuation 46. In the latter case, the handle 10 is to his Swivel axis 11 is pressed with its free end of the handle. This opposite to the handle 16 movement 46 'of the handle 10 can be readily determined by the evaluator 28, because this includes the expected order of the pulse signals in its memory. Depending on which signal is reported to him, the evaluator 28 can distinguish whether the handle is pulled 16 or 46 pressed. Because the evaluator 28 can distinguish this, it can trigger different functions on the electrical control devices and actuators via the control lines 29. Thus, when pressing 46 of the handle 10, for example, the locking system can be set ineffective, so be unlocked.
