Abstract
The invention relates to a power-assisted manual telescopic rocker arm for camera space positioning, and belongs to auxiliary equipment for camera space positioning. The telescopic rocker arm aims to solve the technical problems of large volume, complex structure and inconvenient control of the conventional telescopic rocker arm. The telescopic rocker arm consists of a tripod, a front telescopic arm, a rear telescopic arm, an electric pump, a direction sensor, an electronic control unit and the like, wherein the electric pump is arranged on the outer wall of a telescopic arm sleeve, and the fluid outlet of the electric pump is connected with fluid inlets and outlets of the front telescopic arm and the rear telescopic arm through a control valve of the electronic control unit; the direction sensor is arranged on the outer wall of the telescopic arm sleeve, a pull rope of the direction sensor is connected with the front end of a telescopic rod of the front telescopic arm, and the output end of the direction sensor is connected with the signal input end of the electronic control unit; and the electronic control unit is connected with the electric pump through an electromagnetic valve to control the switching of the electric pump. The power-assisted manual telescopic rocker arm has the advantages of simple and exquisite structure, small volume, stable operation and the like.
Description
Technical field
The present invention relates to the manual telescopic rocker arm of a kind of power-assisted, it belongs to a kind of sterically defined utility appliance of video camera that is used for.
Background technology
The video camera rocking arm more and more is subjected to people's favor, particularly hand-operated rocker arm as video display industry one big utility appliance, because its manually operated dirigibility and accuracy are subjected to liking of photographer deeply.Yet the hand-operated rocker arm operation is subjected to the restriction of its circular motion track, and a lot of complicated exceedingly difficult movements are taken and all are difficult to realize.The demand of taking for satisfying, Recent study has gone out telescopic rocking arm, but it is bulky, complex structure, control inconvenience, shooting effect are undesirable.
Summary of the invention
The objective of the invention is to solve the manual operation that has the existence of video camera rocking arm now restricted by the circular motion track, bulky, the complex structure that exceedingly difficult movements are taken that undesirable and scalable rocking arm exists, the technical matters of control inconvenience provide that a kind of manual operation is not restricted by the circular motion track, volume is little, simple in structure, operate the manual telescopic rocker arm of power-assisted accurately.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
The manual telescopic rocker arm of a kind of power-assisted, form by tripod, front stretching arm, back telescopic arm, telescopic lever, control lever, telescopic arm sleeve pipe and power assisting device, wherein: described power assisting device comprises electric pump, direction sensor and electronic control unit, the cylinder body of described front stretching arm and back telescopic arm is set in the telescopic arm sleeve pipe, and the front stretching arm is fixedlyed connected in alignment with the cylinder body afterbody of back telescopic arm; Described telescopic arm sleeve pipe is contained in the top of tripod; The end of the end of the expansion link of telescopic lever and the expansion link of front stretching arm is connected with control lever, and the tail end of telescopic lever fixed bar is contained in the top of tripod and is positioned at the below of telescopic arm sleeve pipe; Described electric pump is installed on the outer wall of telescopic arm sleeve pipe and the fluid egress point of electric pump is connected with the fluid inlet and outlet of front stretching arm with back telescopic arm cylinder body by operation valve, direction sensor is installed on the outer wall of telescopic arm sleeve pipe, the stay cord of direction sensor is connected with the front end of the expansion link of front stretching arm, the output terminal of direction sensor is connected with the signal input part of electronic control unit, electronic control unit is installed on the tripod, be connected with the reversal valve switching of the switch and the reversal valve that are used for controlling electric pump of electronic control unit and the switch of electric pump.
Described front stretching arm and back telescopic arm adopt any one in hydraulic-driven or the air pressure type of drive.
Because the present invention has adopted technique scheme, during use video camera is fixed on the telescopic arm, when the operation video camera moves in three dimensions, at first can touch the direction sensor that is installed on the front stretching arm, moment that direction sensor can stretch the front stretching arm and the direction signal of intending transmission pass to electronic control unit, open solenoid valve and reversal valve in the electronic control unit, electric pump drives drive medium liquid or gas begins to flow, thereby produce power-assisted and promote the elastic of whole arm body, because the volume of drive cylinder is designed according to lever balance theory in the elastic arm, therefore whole telescopic system is in equilibrium state all the time, when the people when stopping camera motion, direction sensor can be passed to electronic control unit with spacing wave, close electric pump and make drive medium liquid or gas stop to flow, effectively save electric energy.Therefore compared with prior art, the present invention has manual operation and not restricted by the circular motion track, can clearly take exceedingly difficult movements smoothly, exquisiteness simple in structure, and volume is little, leicht fallen D/A and advantage such as operate steadily.
