Wherein the brake carriage 1 is used to provide a mounting platform for the pedal unit 2 and the mobile unit 3. The pedal unit 2 is one of a brake pedal, an accelerator pedal or a clutch pedal, and is used for being stepped on by an operator. The moving unit 3 is connected with the brake frame 1 in a sliding fit manner and is used for correspondingly moving when an operator steps on the pedal unit 2, so that corresponding information is given to the automobile.

Referring to fig. 2 and 4, more specifically, two limiting portions 25 are provided on the mounting surface 22 of the pedal unit 2, and the sliding unit 4 has a sliding portion 41, and the sliding portion 41 is located between the two limiting portions 25 and abuts against the two limiting portions 25. When the slide unit 4 slides on the mounting surface 22 of the pedal unit 2, the slide portion 41 slides between the two limit portions 25.

Referring to fig. 2 and 3, both ends of the telescopic unit 5 in the telescopic direction are rotatably connected to the sliding unit 4 and the moving unit 3, respectively.

In one embodiment, a part of the fixing unit 6 is disposed on the sliding unit 4, and another part of the fixing unit 6 is disposed on the pedal unit 2, so as to fix the position of the sliding unit 4 on the pedal unit 2, and thus fix the angle between the adjusted pedal unit 2 and the brake frame 1 (not shown in the drawings). Wherein, the fixing unit 6 can be selected from accessories such as bolts or screws, and the sliding unit 4 and the pedal unit 2 can be fixed by the bolts or the screws.

In another embodiment, a part of the fixing unit 6 is disposed on the sliding unit 4, and another part of the fixing unit 6 is disposed on the telescopic unit 5, so as to fix the rotation angle between the fixed telescopic unit 5 and the sliding unit 4, and further fix the position of the sliding unit 4 on the pedal unit 2.
