The two torsion springs 8 are used to balance the lateral offset force of the two connecting plates 4, which can not only prevent the pedal 7 from shaking at will, but also balance the lateral force of the driver's stepping on it, and prevent the driver from falling due to unstable force.

[0026] According to a further optimization scheme, a plurality of mounting holes 9 are provided on the top surface of the pedal 7, and an anti-slip ring 10 is fixedly installed in the mounting hole 9. The anti-slip ring 10 is an annular protrusion that can increase the friction between the pedal 7 and the sole and improve the stability of stepping.

[0027] Furthermore, the anti-slip ring 10 can be integrally stamped and formed with the pedal 7 by a punch press, which can reduce the manufacturing cost of the pedal.

[0028] Embodiment 2:

[0029] have Figure 3-4 As shown, the pedal 7 includes a plate frame 11, the top surface of the plate frame 11 is fixedly connected to the outer side surface of the second rotating drum 6, and a plurality of treads 12 are fixedly connected to the inner cavity of the plate frame 11, and the two ends of the treads 12 are respectively fixedly connected to the opposite sides of the plate frame 11, and the treads 12 are used to support the footrest, and the amount of the plate can be further reduced, and the weight of the utility model can be reduced. All treads 12 are divided into two groups, and all treads 12 in each group are arranged parallel to each other. Any tread 12 in each group crosses and is fixedly connected with any tread 12 in another group to form a grid plate. At the same time, two rows of anti-skid strips are fixedly connected to the top surface of the tread 12, and the anti-skid strips include a plurality of latch teeth 13, and all the latch teeth 13 of the anti-skid strips on each side are arranged obliquely and in the same direction, and the latch teeth 13 of the two anti-skid strips are arranged in opposite directions, and the latch teeth 13 are used to hook and bite the driver's soles, increase the friction of stepping, and thus play an effective anti-skid effect.

[0030] In a further optimized solution, the second rotating shaft 5 is also sleeved and rotatably connected with a connecting ring 14, which is rotatably connected to the second rotating shaft 5 through a bearing, and can rotate with the second rotating shaft 5, and can not slide relative to the second rotating shaft 5. The other end of the torsion spring 8 is suspended on one side of the connecting plate 4, and the side of the connecting ring 14 is respectively fixedly connected with a first strip 15 and a second strip 16, one end of the first strip 15 is tilted toward the mounting plate 1, and a spring 17 is fixedly connected to the bottom surface of one end of the first strip 15, and the bottom end of the spring 17 is fixedly connected to the pedal 7, and the one end of the first strip 15 is tilted by the contact of the spring 17. One side of the second strip 16 is detachably connected to the other end of the torsion spring 8, and when the first strip 15 is stepped on and pressed down, it can drive the second strip 16 to abut against the other end of the torsion spring 8, so as to store force on the torsion spring 8, thereby increasing the ability of the pedal 7 to resist lateral force.

[0031] According to a further optimized solution, the pedal 7, the connecting plate 4 and the mounting plate 1 are all made of stainless steel or aluminum alloy.

[0032] The working process of this embodiment is as follows:

[0033] The utility model is installed under the first-level footrest of a heavy truck. When the driver gets on or off the truck, his feet step on the pedal 7. At the same time, due to the driver's stepping, the pedal 7 will shake slightly to offset the impact force caused by the unstable center of gravity of the human body, thereby improving the comfort of the driver.

[0034] When the driver steps on the first strip 15, one end of the first strip 15 will press down the spring 17 and drive the second strip 16 fixedly connected to the connecting ring 14 to deflect by driving the connecting ring 14. The deflection of the second strip 16 can squeeze the other end of the torsion spring 8, thereby storing force in the torsion spring 8, increasing the deflection torque of the torsion spring 8, and preventing the pedal 7 from deviating too quickly, causing the driver's center of gravity to be unstable.

[0035] Furthermore, the first strip 15, the second strip 16 and the connecting ring 14 are all arranged on the two second rotating shafts 5, so that the lateral force can be effectively offset no matter which direction the pedal 7 moves.

[0036] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
