[0002] Formula SAE (FSAE) was founded by the International Society of Automotive Engineers (SAE International) in 1978. Its concept originated from a virtual production factory. It solicited all college student design teams to design and manufacture a small racing car similar to the standard formula. The racing car must have excellent performance in acceleration, braking, and handling, and be stable and durable enough. Due to the limitations of the racing car's appearance, the space in the front cabin is usually small, and the racing car must be suitable for drivers from the 5th percentile female to the 95th percentile male. Therefore, different drivers have different requirements for the position of the racing car pedals. A comfortable pedal position can provide drivers with basic driving protection, allowing drivers to drive the racing car more comfortably and more attentively during the competition.

[0003] After searching, the Chinese utility model patent (CN202210992544.5) discloses a quickly adjustable pedal system, which requires manually adjusting the relative position of the fixing frame and the fixing block to adjust the installation position of the pedal assembly to meet the position usage requirements of the brake pedal. The adjustment process is relatively cumbersome and slow, and it is difficult to meet the requirements of rapid adjustment, so it is necessary to improve the existing technology.

[0010] In a preferred embodiment, it also includes a master cylinder that is linked with the brake support through a balance rod.

[0011] In a preferred embodiment, the riding card and the steel pipe are limitedly matched so that the pedal assembly on the top can only move axially along the direction in which the steel pipe is set.

[0012] In a preferred embodiment: the steel pipe is a steel pipe with a length of not less than 250 mm, a diameter of not less than 12 mm, and an adjustment stroke length of not less than 100 mm.

[0023] The electric adjustable racing pedal assembly described in this embodiment comprises a crossbeam 13 fixed to the frame through the fixed ears 10 at the left and right ends, two steel pipes 14 connected and arranged between the crossbeam 13, and a pedal assembly slidably arranged on the steel pipe 14 through a riding clamp 17. The two steel pipes 14 are assembled with the crossbeam 13 through interference fit. The riding clamp 17 and the steel pipe 14 restrict the five degrees of freedom of the pedal assembly so that the top pedal assembly can only move axially along the direction in which the steel pipe is set. Since the bottom of the pedal assembly is provided with a screw seat 16 that cooperates with the transmission screw 15, the transmission screw 15 can rotate circumferentially under the drive of the transmission device 1, and the upper pedal assembly is driven by the screw seat 16 to deflect along the length direction of the transmission screw 15, so as to adjust the relative position of the upper pedal assembly. The screw seat 16 cooperates with the transmission screw 15 to limit the axial freedom of the pedal assembly in the direction of the steel pipe, making the adjustment displacement of the entire pedal more fixed. The motor as a transmission device is rigidly connected to the transmission screw 15 through a bearing, so that the motor can drive the transmission screw 15 to flexibly adjust the pedal position.

[0024] From the perspective of component composition, the pedal assembly not only includes a brake support 45 with an upper end connected to the brake pedal 18 and a lower end hinged to the base plate 19, a throttle support 21 with an upper end connected to the throttle pedal 34 and a lower end hinged to the base plate 19, and a gas spring 25 linked to the throttle support, but also includes a throttle sensor 35 connected to the rotating shaft 33 through a coupling 39 and a master cylinder 43 linked to the brake support 45 through a balance bar 44.

[0025] From the connection relationship between the components, the throttle cable support 9 is fixed to the fixed ear piece 10 by bolts, the screw seat 16 is fixed to the middle of the base plate 19 by bolts and a ball bearing is fixed inside by interference fit, the riding card 17 is distributed on both sides of the screw seat 16 and is fixed to the base plate by bolts, the brake overtravel switch is fixed to the base plate 19 by bolts, the balance bar 44 cooperates with the brake support 45 to connect with the two brake master cylinders 43, the oil pot 5 is connected to the master cylinder 43 through a pipe, the brake support 45 is fixed to the base plate 19 by bolts, and the brake pedal 18 is fixed to the brake support 45 by bolts; the gas spring 25 is fixed to the base plate at the throttle position by bolts, and is connected to the throttle support 21 through the light rod 22, the throttle cable is fixed to the throttle support 21 by bolts, the throttle support 21 is fixed to the base plate at the throttle through the rotating shaft 33, the throttle cable is fixed to the throttle support 21 by bolts, and the throttle pedal 34 is fixed to the throttle support 21 by bolts. The throttle sensor 35 is fixed above the bottom plate where the throttle sensor 35 is located by bolts, and the rotating shaft 33 is connected to the throttle sensor 35 by a coupling 39 so that the angular displacement energy of the throttle support 21 can be transmitted to the throttle sensor 35 .

[0026] From the setting parameters of the components, in order to meet the general needs, the thickness of the bottom plate 19 of this embodiment is 6mm, and the material is 7075 aluminum alloy; the length of the steel pipe 14 is set to be not less than 250mm, the diameter is set to be not less than 12mm, and the adjustment stroke length is not less than 100mm; the wire diameter of the screw rod 15 is set to be not less than M12, the length is set to be not less than 270mm, the thread length is not less than 200mm, and the stainless steel rod is processed with a D-shaped notch at its end. In short, the parameter adjustment of the above components without changing the actual use needs of the user is regarded as a simple replacement of this embodiment.

[0027] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
