[0041] like Figure 1-Figure 7As shown, in this embodiment, the pedal assembly includes a base 1, a pedal 2, an elastic member 3, and a transmission shaft 4. The base 1 defines a mounting hole 11, and the pedal 2 is rotatably mounted on the base 1. The pedal 2 defines a connecting hole 21, and the inner circumferential wall of the connecting hole 21 is provided with a positioning groove 22 and a fixing hole 23. One end of the elastic member 3 is connected to the base 1, and the other end of the elastic member 3 is connected to the pedal 2. The transmission shaft 4 includes a transmission portion 41, a positioning portion 42, and a snap portion 43. The positioning portion 42 and the snap portion 43 are both connected to the outer circumferential surface of the transmission portion 41. The transmission portion 41 passes through the mounting hole 11 and the connecting hole 21. The positioning portion 42 is slidably inserted into the positioning groove 22, and the snap portion 43 is snapped into the fixing hole 23. Specifically, the number of positioning grooves 22 can be set to multiple to increase structural stability. The positioning part 42 is a reinforcing rib, and the snap part 43 is an elastic snap. Both side walls of the base 1 are provided with mounting holes 11. The pedal 2 is located between the two side walls of the base 1. The transmission part 41 is passed through the mounting hole 11 of the base 1 and the connecting hole 21 of the pedal 2. The positioning part 42 is plugged and fixed in the positioning groove 22. The positioning groove 22 has a certain limiting effect on the positioning part 42, and the two side walls of the positioning part 42 are in surface contact with the inner end face of the positioning groove 22, and the connection is firm and stable. Drive shaft 4 is made of modified engineering plastic, featuring wear resistance, high structural strength, and good toughness. The base 1, pedal 2, and drive shaft 4 fit tightly together, and the shoulder of drive shaft 4 and the mounting hole 11 of base 1 are both cylindrical, with a smooth transition and no abrupt structures. This reduces the risk of friction-induced gap expansion between the drive shaft 4 and base 1, preventing the ingress of dust and gravel. Furthermore, the snap-fit portion 43 engages and secures with the fixing hole 23 of pedal 2, providing a positioning function and limiting the axial and circumferential direction of the transmission portion 41. The pedal 2 can rotate relative to the base 1 under the action of the transmission portion 41, resulting in a simple structure, easy assembly, and low cost. The elastic member 3 is a spring, with its ends connected to the base 1 and pedal 2, respectively. Under the action of an external force and the thrust of the elastic member 3, the pedal 2 can reciprocate relative to the base 1, i.e., between its initial position and the full throttle position.

[0042] Further, refer to Figure 3 and Figure 4 The transmission shaft 4 further includes a fixing portion 44. The inner peripheral wall of the connecting hole 21 is further provided with a pressing portion 24. The top surface of the fixing portion 44 abuts against the pressing portion 24. Specifically, the fixing portion 44 is a reinforcing rib. The pressing portion 24 is protruding from the inner peripheral wall of the connecting hole 21. The positioning portion 42 corresponds to the positioning groove 22 one-to-one. The fixing portion 44 and the pressing portion 24 are provided correspondingly. The positioning portion 42 is inserted and fixed in the positioning groove 22. The fixing portion 44 and the pressing portion 24 have an interference fit. Along the radial direction of the transmission portion 41, the pressing portion 24 limits the fixing portion 44, further improving the relative stability between the transmission shaft 4 and the pedal 2, and preventing them from moving relative to each other.

[0043] Further, continue to refer to Figure 3 and Figure 4 The length directions of the positioning portion 42, the fixing portion 44, and the positioning groove 22 are all arranged parallel to the axial direction of the transmission portion 41. Specifically, the axial direction of the transmission portion 41 is consistent with the plug-in and pull-out direction of the transmission shaft 4 relative to the connecting hole 21, and the length direction of the positioning groove 22 extends along the axial direction of the transmission shaft 4. The length direction of the positioning portion 42 is parallel to the length direction of the positioning groove 22. The positioning portion 42 is inserted and fixed in the positioning groove 22. The positioning groove 22 has a certain limiting effect on the positioning portion 42, and the two side walls of the positioning portion 42 are in surface contact with the inner end surface of the positioning groove 22, so that the connection is firm and stable. The length direction of the fixing portion 44 is parallel to the axial direction of the transmission shaft 4. The fixing portion 44 is arranged corresponding to the abutting portion 24, and the abutting portion 24 plays a limiting role on the fixing portion 44.

[0044] Further, continue to refer to Figure 3 and Figure 4 The positioning portion 42, the fixing portion 44, the buckle portion 43 and the transmission portion 41 are integrally formed. Specifically, the positioning portion 42, the fixing portion 44, the buckle portion 43 and the transmission portion 41 are integrally formed by casting or the like, and have high structural strength and long service life.

[0045] Further, refer to Figure 5 The transmission shaft 4 also includes a magnetic portion 45. A mounting groove is defined at the end of the transmission portion 41, and the magnetic portion 45 is disposed within the mounting groove. Specifically, the magnetic portion 45 is a magnet, and a stopper 46 is protruding from the inner sidewall of the mounting groove. The stopper 46 abuts against the magnetic portion 45. The magnetic portion 45 is pressed into the mounting groove of the transmission shaft 4, and the outer peripheral wall of the magnetic portion 45 abuts against the stopper 46, preventing the magnetic portion 45 from falling off and ensuring a secure connection.

[0046] Further, refer to Figure 6 The base 1 is provided with a first engaging slot 12, and the pedal 2 is provided with a second engaging slot 25. One end of the elastic member 3 is engaged with the first engaging slot 12, and the other end of the elastic member 3 is engaged with the second engaging slot 25. Specifically, in the vertical direction, the elastic member 3 is located between the base 1 and the pedal 2, and is connected and fixed by the first engaging slot 12 of the base 1 and the second engaging slot 25 of the pedal 2. The pedal 2 can reciprocate relative to the base 1 under the action of an external force and the thrust of the elastic member 3, that is, the pedal 2 reciprocates between the initial position and the full throttle position.

[0047] Further, continue to refer to Figure 6There are multiple elastic members 3, and the multiple elastic members 3 are nested in sequence. Specifically, in this embodiment, there are two elastic members 3, each having different diameters. The elastic member 3 with the larger diameter is mounted on the elastic member 3 with the smaller diameter. The two elastic members 3 extend and retract simultaneously, allowing the pedal 2 to reciprocate relative to the base 1 between the initial position and the full throttle position. The two elastic members 3 can enhance the reliability and stability of the elastic extension and retraction, preventing the elasticity of the elastic member 3 from failing due to excessive pressure on the pedal 2. Optionally, there are multiple elastic members 3, and the diameters of the multiple elastic members 3 decrease in sequence and are nested.

[0048] Further, refer to Figure 7 The pedal assembly also includes a sensor 5 and a connector 6. The sensor 5 has a through-hole 51, and the base 1 has a threaded hole 13. The connector 6 passes through the through-hole 51 and is threadedly connected to the threaded hole 13. Specifically, the sensor 5 is a position sensor, and the connector 6 is a screw. The sensor 5 has a circular shape, and the internal circuit board is also designed to be circular. The sensor 5 is small and has a simple packaging. The sensor 5 is installed on the side of the base 1 through the connector 6 and does not move with the pedal 2. In addition, the connection harness and wiring are easier to operate according to different installation requirements.

[0049] This embodiment also provides a vehicle, including a cab and a pedal assembly, wherein the pedal assembly is mounted on the cab. Specifically, a pedal 2 is rotatably mounted on a base 1, a connecting hole 21 is provided on the pedal 2, a positioning groove 22 and a fixing hole 23 are provided on the inner peripheral wall of the connecting hole 21, a positioning portion 42 and a buckle portion 43 are both connected to the outer peripheral surface of a transmission portion 41, the transmission portion 41 is passed through the mounting hole 11 and the connecting hole 21, the positioning portion 42 is slidably inserted into the positioning groove 22, and the connection is firm and stable, thereby improving the reliability and stability of the vehicle cab control pedal assembly and reducing the ingress of dust and gravel. The buckle portion 43 is engaged with the fixing hole 23, and limits the axial and circumferential directions of the transmission portion 41. The pedal 2 can rotate relative to the base 1 under the action of the transmission portion 41, and has a simple structure, is easy to assemble, and reduces the cost of the vehicle. One end of the elastic member 3 is connected to the base 1, and the other end of the elastic member 3 is connected to the pedal 2. The pedal 2 can reciprocate relative to the base 1 under the action of external force and the thrust of the elastic member 3, that is, the pedal 2 reciprocates between the initial position and the full throttle position, thereby improving the driving smoothness of the vehicle.
