Description

Electrochemical energy source suitable especially for hand operated electric tools Technical field
The solution covers an electrochemical energy source suitable especially for hand operated electric tools such as drills, grinders, screwdrivers and others.
Prior art
Hand operated electric tools are nowadays irreplaceable helpers making work easier for various craftsmen. The feeder cable of any tool poses a potential source of electrical accidents and makes work less comfortable. Owing to the technological process in the storage battery development it is possible to replace, within a certain tool segment, the electrical grid source with an electrochemical energy source - storage battery.
The storage batteries to be used in tools with electrochemical energy sources are manufactured as a set of two or more electrochemical cells connected in series, parallel or connected as a combination of series and parallel connections.
At present the storage batteries are manufactured with exactly defined voltage, arising from the voltage of the electrochemical cell, or cells (connected in series), and exactly defined capacity arising from the capacity of the electrochemical cell, or cells (connected in parallel). Therefore their use is limited and does not allow the full use of the advantages of electrochemical sources. Nowadays you can buy a great number of storage batteries of various voltages and capacities whose parameters are final and invariable.
Through the submitted invention we strive to provide the hand operated electric tools with such an electrochemical energy source whose capacity may be increased, if needed, and at the same time the nominal voltage is preserved.
Nature of the Invention
The goals set by the above specified task are met by an electrochemical energy source consisting of an enclosure comprising a set of storage cells connected in series and their connection is connected to two connectors. The enclosure is provided on the outside with a guide and holding slot for installation of another similar electrochemical source and also with an arresting mechanism whose function is linked to and which is attached to the enclosure. The standard protective electronics protect the storage cells against overloading during their charging as well as while they are being used.
Owing to the design of the electrochemical source in accordance with the submitted invention it is possible not only to connect the storage battery to a particular tool but also interconnect more storage batteries. If needed, it is possible to connect to the particular electrochemical source another similar electrochemical source by simply inserting the source into the guide slot on the outside of the enclosure. The result of this connection of the storage batteries is the possibility of increasing the capacity of the total source several times, if needed. The final capacity of the source connected this way is a sum of capacities of identical storage batteries. Owing to this it is possible to use the electrochemical energy source also within the segments which with respect to the limited capacity of the storage batteries still prefer the use of electrical grid sources. In practice this means that if the user needs achieving a higher capacity of the source, the user may interconnect more storage batteries.
Summary of Drawings
The invention is explained by means of enclosed drawings where
Fig. 1 schematically shows the perspective view of an electrochemical energy source with four storage cells and two external connecters,
Fig. 2 shows the front view of an electrochemical energy source,
Fig. 3 shows the front view of two interconnected electrochemical
energy sources,
Fig. 4 shows the lateral view of the set of two interconnected electrochemical
energy sources,
Fig. 5 shows the perspective view of the set of two interconnected
electrochemical energy sources.
Examples of Carrying out of the Invention
The electrochemical energy source, which is a subject of protection in accordance with fig. 1 and fig. 2, consists of enclosure 1, comprising a set of storage cells 2 connected in series. For the purposes of an example we use a storage battery with four cells, however it is possible to use any number of cells connected in series. This connection is connected to two connectors 3, 4 . Enclosure 1 is provided on the outside with guide and holding slot 5 for the purposes of installing another similar electrochemical energy source with arresting mechanism 6 functionally as well as structurally connected to enclosure 1.
Through the said connectors 3^ 4 it is possible to connect particular storage batteries in parallel which increases the total capacity of the storage batteries connected this way with the capacities of the connected storage batteries. Owing to this you can get a final effect - the tool fed by batteries connected this way will keep working several times longer.
Figures 3,4 and 5 show two interconnected storage batteries. For the purposes of simplifying the connection of storage batteries you can use guide slot 5. Once they are inserted, the inserted batteries are locked in a given position by means of arresting mechanism 6, which protects the storage batteries from slipping out accidentally. Protective electronics 7 are standard and protect storage cells against overloading during charging as well as while they are being used.
If a worker finds out, while using a hand operated electric tool, that as a result of a reduced capacity of a connected electrochemical energy source the performance is dropping and therefore also the output of the tool is dropping as well, the worker will connect another electrochemical energy source to the particular energy source by simply inserting it in guide slot 5. Thus the worker will increase the source capacity while the voltage remains the same.
Industrial Appplicability
The electrochemical energy source can be used, in accordance with the submitted solution, on the basis of its design and owing to its simple handling, in all those branches of industry where hand operated electric tools are being used. It is also suitable for craftsmen and do-it-yourself men.
