The left wing 3, the right wing 4, and the connecting plate 5 are an integrally formed structure and are all made of steel plates. The connecting plate 5 is connected to the bottom of the middle position between the left wing 3 and the right wing 4. The left wing 3 and the right wing 4 are arranged in parallel and perpendicular to the connecting plate 5. The spacing between the left wing 3 and the right wing 4 depends on the width of the active arm 12 and the driven arm 13. The front ends of the left wing 3 and the right wing 4 are each provided with at least two limiting protrusions 6. In this embodiment, the limiting protrusions 6 are square plates and there are two of them. A card slot 8 is formed between the limiting protrusions 6, and also includes a positioning plate 9. The positioning plate 9 is a steel plate with assembly grooves at both ends thereof that are adapted to the card slot 8 and the limiting protrusion 6. The assembly groove is engaged with the limiting protrusion 6, and the positioning plate 9 is supported by the bottom surface of the card slot 8; the positioning plate 9 is welded and fixed to the left wing 3 and the right wing 4. The positioning plate 9 can be processed in advance as needed to ensure strength and size requirements, and it is convenient to design individually according to needs, with the advantages of low cost and strong adaptability.
[0026] The pedal 2 includes a profile structure, and a slot 8 along the length of the pedal 2 is provided on the side of the profile close to the lower arm 1. It also includes a connecting piece 7, which is inserted into the slot 8 and has a threaded hole. The positioning plate 9 also has a threaded hole. The pedal 2 is fixedly connected by bolts passing through the positioning plate 9 and the threaded holes of the connecting piece 7; the positioning plate 9 is welded and fixed to the left wing 3 and the right wing 4.
[0027] In order to realize the four-bar linkage structure, the described structure also includes a main pedal 2 assembly and a slave pedal 2 assembly, wherein the pedal 2 is mounted on the main pedal 2 assembly and the slave pedal 2 assembly; the main pedal 2 assembly includes a drive motor 10, a mounting base, a master arm 12, and a slave arm 13; one end of the master swing arm is fixedly mounted on the driving shaft, which is mounted on the mounting base and driven to rotate by the drive motor 10; the other end of the master swing arm is connected to the lower swing arm 1 via pivot 1; one end of the slave swing arm is connected to the mounting base via pivot 2, and the other end is connected to the lower swing arm 1 via pivot 3; the drive motor 10 drives the driving shaft to rotate, thereby driving the master arm 12 and the lower swing arm 1 to swing, and the swing of the lower swing arm 1 simultaneously drives the slave arm 13 to swing, and the lower swing arm 1, the master arm 12, the slave arm 13 and the mounting base form a four-bar linkage mechanism. The drive motor 10 drives the drive shaft 14 to rotate in both positive and negative directions, driving the master arm 12 to swing back and forth, thereby driving the slave arm 13 and the lower swing arm 1 to swing back and forth.
[0028] The pedal 2 includes a main body 15 and a mounting portion 16 extending from the upper left side of the main body 15. A slot 8 is provided below the mounting portion 16. There are two slots 8. The mounting portion 16 is a square tube structure, including a square tube 17 on the left and a square tube 2 18 on the right. The square tube 17 and the square tube 2 18 are formed by a partition, and the upper plate of the square tube 2 18 is an upwardly inclined plate. The two slots 8 are correspondingly provided on the lower sides of the square tube 1 17 and the square tube 2 18. This structural design makes the upper side of the square tube 2 18 into a triangular structure, thereby increasing stability. At the same time, the inclined surface protruding from the surface of the pedal 2 can play a blocking role, and the inclined surface can also play a buffering role to avoid discomfort to the user. At the same time, the connecting piece 7 can slide in the slot 8 to change the relative position to meet different assembly requirements.
[0029] The mounting base is formed by stamping and bending steel plate. It has a U-shaped structure, with a mounting bracket 28 welded to its top plate. The mounting bracket 28 consists of a bottom plate welded to the top plate and a vertical plate 19 for securing to the vehicle body. The vertical plate 19 has a recessed groove in the middle, with mounting holes 29 provided on either side of the groove. The vertical plate 19 also includes a reinforcing plate 20, which spans the groove and fits in place with the vertical plate 19. The reinforcing plate 20 has connecting holes corresponding to the mounting holes 29. Fixing bolts pass through the mounting holes 29 and the connecting holes to secure the mounting base to the vehicle body. This structure reduces the weight of the mounting base without sacrificing strength, making it suitable for vehicle body applications.
[0030] In this solution, adjustment holes 21 are provided on both the top and bottom plates. A pin hole 23 for mounting the drive shaft 14 is provided on the main swing arm. A mounting slot 22 is provided on the lower side of the active arm 12, which communicates with the pin hole 23. A locking block 24 is also provided.

During assembly, the positioning bevel 26 abuts against the inner side of the positioning slot 25. The locking block 24 is a rubber member. This structural design allows the locking degree of the drive shaft 14 to be adjusted as needed. If the friction between the two is insufficient, the locking force can be tightened by adjusting the locking bolt.
[0031] A buffer groove 27 is provided on the upper surface of the driven arm 13, and a bracket 28 is installed in the buffer groove 27. The bracket 28 is fixedly connected to the driven arm 13 by screws. The bracket 28 is formed with a circular mounting hole 29, and the side wall of the mounting hole 29 is provided with an insert 30. It also includes a limiting column 31. After the limiting column 31 is inserted into the insert 30, it is installed in the buffer groove 27 together with the bracket 28.
