Description

Technical Field

[0001] The invention relates to the technical field of automobile testing, in particular to a vehicle throttle brake device. Background Art

[0002] Automobile testing refers to testing of various parameters of the automobile, and automobile testing often requires extreme testing, such as collision testing. At this time, real-life driving is extremely dangerous, so robots are needed to simulate driving for testing; a car testing robot is a robot that can control the throttle and brakes of a car. The throttle and brakes are controlled through different instructions from the safety officer, thereby completing car tests with a higher degree of danger.

[0003] The throttle and brake of the current automobile testing robot are respectively controlled by separate pistons or motors. For example, a throttle brake robot with a publication number of CN218766027U discloses a car seat, and two movable blocks are movably installed on the outer surface of the car seat. The utility model cooperates with a movable plate and a push plate, first installs the movable plate above the throttle and brake of the car, fixes it through a support frame, and then places two push plates on both sides of the top of the movable plate. When the device controls the piston rod to push downward through the piston, the piston rod pushes the push plate to collide with the surface of the movable plate, and one end of the movable plate is pressed downward, and the other end is tilted upward, so that when the device is testing the car, when the car throttle is stepped on by the push plate, the brake cannot be stepped on at the same time, and vice versa, so as to prevent the throttle and brake from being stepped on at the same time during the test, thereby preventing the increase of fuel consumption or the wear of the brake disc, and preventing the vehicle from suddenly offset, further reducing the error of the experimental results.

[0004] The above technical solution requires two pistons to control the throttle and brake respectively. Although a push plate is provided to prevent the piston rods from working simultaneously, the push plate plus double piston barrier does not facilitate the linkage control of the throttle and brake. Therefore, the present application proposes a vehicle throttle brake device that uses a single drive motor to control the throttle and brake. Summary of the invention

[0005] The present invention provides a vehicle throttle brake device, which aims to solve the problem that the above-mentioned throttle brake robot uses two pistons to control the throttle and brake respectively.
