Description

Technical Field

[0001] The utility model relates to the technical field of driverless technology, in particular to a fixing mechanism for the accelerator pedal of a vehicle driving robot. Background Technique

[0002] The use of the accelerator pedal directly affects the driver's control of speed. Therefore, when designing the accelerator pedal, great attention is paid. The current accelerator pedals are divided into two types. One is the hanging type, and the normal accelerator is the hanging type. The other is the floor type pedal. Since the rotating shaft of the floor type pedal is located at the bottom of the pedal, the whole sole of the foot can step on it, and the pedal itself is a fulcrum. The calf and ankle can control the pedal more easily, correspondingly improving the accuracy of controlling the pedal under the foot and reducing the fatigue. The accelerator pedal is a control pedal for controlling the acceleration of the vehicle. For gasoline vehicles, the accelerator pedal does not control the fuel volume, but adjusts the intake air volume of the engine by controlling the opening degree of the engine throttle valve, so as to achieve the purpose of adjusting the power output of the engine.

[0003] When testing some performances of a vehicle or developing a driverless vehicle, in order to reduce the risk coefficient, a vehicle driving robot is developed; using a robot to replace the experimental personnel can improve the safety coefficient. The fixing mechanism of the existing technology robot acting on the accelerator pedal can only rotate and press the accelerator pedal along its fixed arc, and the accelerator pedal can only rotate on its inherent arc; in addition, the structure of the fixing mechanism is fixed, which will cause a certain misalignment between the fixing mechanism of the robot and the accelerator pedal, and there will be a situation where the accelerator pedal cannot be accurately controlled after the vehicle travels on a bumpy road section; for example, the fixing method of the "swing arm" and "pedal widening assembly" recorded in a Chinese patent, a pedal driving robot for driverless testing (authorized announcement number CN213874973U), is also a direct fixing method without an adjustment structure, and it can only rotate on the inherent arc. In the case that the accelerator pedal can only rotate on its inherent arc, it will also cause a certain misalignment with the accelerator pedal, and there will also be a situation where the accelerator pedal cannot be accurately controlled after the vehicle travels on a bumpy road section.

[0004] Based on this, a fixing mechanism for the accelerator pedal of a vehicle driving robot is specifically proposed to solve the above problems. Content of the Utility Model

[0007] After installing the vehicle driving robot inside the vehicle and using the pressing plate to act on the accelerator pedal, start the vehicle driving robot to drive the main swing arm to swing and press the accelerator pedal along the fixed arc. During the rotation of the accelerator pedal on its inherent arc, start the telescopic adjustment of the lifting arm to complete the adjustment of the lifting position of the pressing plate; then start the angle adjustment seat to control the rotation angle position adjustment of the pressing plate through the angle adjustment seat; then use the electric telescopic rod C to control the sliding position of the angle adjustment seat on the pressing plate to complete the adjustment of the pressing plate along the main body direction of the accelerator pedal; that is, through the combination of the lifting arm, the angle adjustment seat and the electric telescopic rod C, the position of the pressing plate is adjusted in multiple directions, realizing flexible cooperation with the position change during the rotation of the accelerator pedal on its inherent arc, ensuring that the pressing plate always stably adheres to the accelerator pedal, so as to always stably control the accelerator pedal by the pressing plate, and avoiding the situation where the accelerator pedal cannot be accurately controlled after the vehicle travels on a bumpy road section.
