Description

Technical Field

[0001] The utility model relates to an electric regulating system of a pedal assembly for a university formula racing car, belonging to the field of university formula racing cars. Background Art

[0002] According to the competition rules, each team must have at least four drivers in all dynamic events, and each driver may not participate in more than two events. Due to the different heights of the drivers, the pedal position needs to be adjusted frequently to adapt to the driving posture of drivers of different heights if the seats cannot be adjusted. The traditional mechanical manual adjustment mechanism used in the racing car is not only cumbersome, time-consuming and laborious, but also requires the cooperation of multiple people to complete. At the same time, it often cannot be adjusted after long-term use due to deformation of the force positioning hole, resulting in the driver being unable to drive the car in the most comfortable posture, affecting the competition results.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0028] like Figure 1-2 As shown, the utility model provides an electric adjustment system of a pedal assembly for a student formula racing car, comprising: an oil pot 101, a brake master cylinder 102, a brake pedal arm 103, a base plate 104, a brake pedal 105, an accelerator pedal 106, an accelerator pedal arm 107, an optical axis hanging ear 108, an optical axis 109, a linear slider 110, a lead screw 111, a lead screw nut hanging ear 112, a lead screw nut 113, a motor hanging ear 114, a reduction motor 115, a coupling 116, and a hanging ear piece 117.

[0029] The electric adjustment system is arranged at the bottom of the base plate 104, wherein at least four linear sliders 110 are respectively fixedly arranged at the four corners of the base plate 104 by bolts, and two optical axes 109 respectively pass through the linear sliders 110 on both sides of the base plate 104, and the two ends of the optical axes 109 are respectively fixedly arranged on the vehicle frame. In the middle position of the bottom of the base plate 104, located between the two optical axes 109, a lead screw 111 is rotatably supported and arranged, and a reduction motor 115 is supported and arranged on the vehicle frame, and the output end of the reduction motor 115 is fixedly connected to one end of the lead screw 111. By driving the reduction motor 115 to rotate, the lead screw 111 is driven to rotate, thereby driving the base plate 104 and the brake pedal 105 and the accelerator pedal 106 arranged on the base plate 104 to move.

[0030] In the present practical information, as a preferred embodiment, the number of the linear sliders 110 is four.

[0031] On the base plate 104, a brake pedal arm 103 and an accelerator pedal arm 107 are rotatably arranged on both sides of the top of the base plate 104, a brake pedal 105 is fixedly arranged at one end of the brake pedal arm 103, an accelerator pedal 106 is fixedly arranged at one end of the accelerator pedal arm 107, an oil pot 101 is arranged on the base plate 104, and a brake master cylinder 102 is arranged on the base plate 104 and connected to the brake pedal.

[0032] The lead screw nut ear 112 is fixedly arranged at the bottom of the base plate, the lead screw nut 113 is fixedly arranged between the base plate 104 and the lead screw nut ear 112, the lead screw 111 is matched with the lead screw nut 113, and the lead screw 111 and the lead screw nut 113 can move relative to each other. The lead screw nut 113 and the lead screw 111 are matched through threads, so that when the lead screw 111 rotates, the lead screw nut 113 can slide back and forth.

[0033] At least four hanging ears 117 are fixedly arranged on the frame, and an optical axis hanging ear 108 is fixedly arranged on each hanging ear 117, and both ends of the optical axis 109 are fixedly arranged on the optical axis hanging ears 108. The motor hanging ear 114 is fixedly arranged on the frame, close to one end of the lead screw 111, and a reduction motor 115 is fixedly arranged on the motor hanging ear 114. The output end of the reduction motor 115 is connected to one end of the lead screw 111 through a coupling 116 to transmit power to the lead screw.

[0034] In the utility model, as a preferred embodiment, the number of the hanging ear pieces 117 is four.

[0035] In the present utility model, as a preferred embodiment, the length of the lead screw is 200 mm and the diameter of the optical axis is 12 mm.

[0036] The working principle is:

[0037] When the driver needs to adjust the position of the pedal assembly, he presses the adjustment button on the steering wheel, and the reduction motor 115 receives the signal and starts to rotate. The motor output shaft drives the lead screw 111 to rotate through the coupling 116, transmitting the power of the motor. The lead screw nut 113 matched with the lead screw 111 converts the rotational motion of the lead screw into the forward and backward motion of the lead screw nut. The lead screw nut is fixed to the lead screw nut hanging ear 112 by bolts. The lead screw nut 113 and the bottom plate vector of the pedal assembly drive the entire pedal assembly to move forward and backward, realizing the electric adjustment of the pedal assembly. At the same time, when the driver adjusts the pedal assembly to a comfortable position, the threaded fit between the lead screw and the lead screw nut 113 also plays a certain self-locking role to prevent the pedal assembly from shaking forward and backward.

[0038] At the same time, the pedal assembly slides on a steel optical shaft 109 with a diameter of 12 mm through four linear sliders 110 on both sides of the bottom. The main functions of the optical shaft are: first, as the force-bearing part of the electric adjustment system, it prevents the lead screw from bending due to the force applied by the driver when stepping on the pedal and failing to transmit the motor power; second, it cooperates with the linear slider to enable the pedal assembly to slide back and forth smoothly, minimizing the resistance encountered by the motor and the lead screw when rotating. The two ends of the two optical shafts 109 are respectively fixed with an optical shaft hanging ear 108 by bolts, and the optical shaft hanging ear 108 is fixed with a hanging ear piece 117 by bolts, which guides the force of the driver stepping on the accelerator pedal and the brake pedal to the frame, reduces the force and deformation of the lead screw, optical shaft and other easily bent parts, and increases the durability of the entire pedal assembly electric adjustment system.

[0039] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
