The invention discloses a bottom plate fixing device for a throttle control device, which is characterized in that the bottom plate fixing device comprises a four-bar linkage mechanism formed by hinged ends of four connecting rods, and a pair of pairs of the four-bar linkage mechanism The corners form an abutment end for abutting with the driver's seat and the cab of the car, and the four-bar linkage is provided with an angle adjustment structure for controlling the diagonal opening and closing angle and thereby adjusting the distance between the two abutting ends. The four-bar linkage There is also a compression screw rod on the upper part, the compression screw rod is arranged vertically as a whole and rotatably fits in a compression nut fixed on the four-bar linkage mechanism, and the lower end of the compression screw rod is used to press the throttle control The bottom plate of the device is pressed and fixed. The device has the advantages of simple structure, very convenient and quick fixing operation of the bottom plate, good fixing effect, and no damage to the structure of the vehicle itself.
Description
technical field [0001] The invention relates to an accelerator control device for automobile emission test, in particular to a bottom plate fixing device for the accelerator control device. Background technique [0002] Before the automobile is produced and leaves the factory, it is necessary to carry out the emission test of the vehicle operating condition method to check whether the engine emission can meet the requirements when the vehicle is in different environments. During the emission test of the vehicle working condition method, the vehicle is located in the test environment chamber and is in an overhead state, and the test environment chamber provides different temperature environment simulations. Then it is necessary to depress the accelerator pedal of the vehicle to accelerate the wheels to a certain speed, then stabilize at a certain speed and maintain it for a certain period of time. [0003] In the prior art, the accelerator pedal is generally stepped on manua...
