Description

Technical Field

[0001] The utility model relates to the field of two-wheeled vehicles, in particular to an automatic footrest mechanism. Background Art

[0002] At present, the footrests of two-wheeled vehicles such as two-wheeled electric vehicles and motorcycles are opened and closed by manual foot stepping. The above operations are rather troublesome during the process of closing or opening the footrest when frequently using the vehicle. Sometimes, the rider forgets to retract the footrest while riding, which may trigger potential driving hazards.

[0003] Two-wheeled vehicles such as motorcycles and electric vehicles are common means of transportation for traveling in daily life. These vehicles usually adopt footrests as parking auxiliary mechanisms. In the common footrest structures, one end of the footrest is rotatably connected to the bottom side of the vehicle body steel frame, and the footrest is connected to the vehicle body through parts such as a tension spring. The recovery of the tension spring keeps the footrest in a retracted state. When the footrest needs to be opened in the parking state, the user needs to stand on one foot and then use the other foot to dial the end of the footrest. After opening the footrest, the vehicle body is tilted so that the end face of the footrest contacts the ground, and a certain angle is formed between the vehicle body and the ground to realize the parking support of the vehicle; when the vehicle needs to be switched to the driving state, the footrest needs to be retracted. At this time, a retracting force needs to be applied to the footrest, and the tension spring pulls the footrest back to the closed state. Summary of the Invention

[0015] The present utility model will be further described below with reference to the drawings and embodiments. Embodiment

[0016] As Figure 1 、 2, an automatic footrest mechanism shown in Fig. 3, includes a support rod 4, a mounting plate 2 and a driving actuator assembly. The top of the support rod 4 is provided with a clamp seat. The upper part of the clamp seat is provided with a mounting plate 2. The lower part of the clamp seat passes through a fixed shaft. The mounting plate 2 is fixedly installed on the vehicle body frame. The lower left part of the mounting plate 2 is provided with a spring post 7. The middle of the support rod 4 is provided with a mounting seat 6. A tension spring 3 is arranged between the mounting seat 6 and the spring post 7. The fixed shaft is connected to the driving actuator assembly 1. The driving actuator assembly includes an upper housing 11, a lower housing 1 and a motor 12. A fixing screw 10 passes through a rotating arm 9 and inserts into the upper housing 11. The rotating arm 9 is connected to an output shaft 13. The tooth part of the output shaft 13 meshes with the external teeth of a five-stage gear 14. The internal teeth of the five-stage gear 14 mesh with the internal teeth of a four-stage gear 18. The external teeth of the four-stage gear 18 mesh with the internal teeth of a two-stage gear 16. A fixed shaft c passes through the two-stage gear 16 and the one-stage gear 19. The fixed shaft c is fixed on the inner walls of the upper housing 11 and the lower housing 1. The worm on the motor 12 meshes with the external teeth of the one-stage gear 19. The one-stage gear 19, the two-stage gear 16, the four-stage gear 18 and the five-stage gear 14 are rotatably arranged. A circuit board is arranged in the lower housing 1.

[0017] The cross-section of the clamp seat is U-shaped, and the outer wall of the upper part of the clamp seat is arc-shaped.

[0018] The upper right part of the mounting plate 2 is recessed to form an arc-shaped bayonet, and the arc-shaped bayonet contacts a limit nut 8.

[0019] A fixed shaft a passes through the five-stage gear 14. The fixed shaft a is fixed on the inner walls of the upper housing 11 and the lower housing 1. A fixed shaft b passes through the four-stage gear 18 and the three-stage gear 15. The fixed shaft b is fixed on the inner walls of the upper housing 11 and the lower housing 1. The internal teeth of the three-stage gear 15 mesh with the external teeth of the two-stage gear 16. The external teeth of the three-stage gear 15 mesh with the external teeth of the one-stage gear 19. The fixed shaft a, the fixed shaft b and the fixed shaft pass through the circuit board.

[0020] The upper housing 11 and the lower housing 1 are connected together.

[0021] The worm is provided with tooth bodies.

[0022] During use, the motor 12 drives the worm to drive the first-stage gear 19 to rotate. The first-stage gear 19 and the second-stage gear 16 rotate simultaneously, and the fourth-stage gear 18 follows to rotate and drive the fifth-stage gear 14 to rotate. The fifth-stage gear 14 drives the tooth part of the output shaft 13. The tooth part is fan-shaped and rotates at an angle. The driving actuator assembly can drive the support rod 4 to open or close in a moving state. The driving actuator assembly 1 has a circuit controller and can receive relevant information of the vehicle. The vehicle information includes vehicle speed signal, brake signal, vehicle angle attitude, and support rod angle and other information. After receiving the relevant data provided by the vehicle, the driving actuator assembly determines whether to meet the conditions for executing the opening or closing function of the support rod 4, ensuring driving safety. This solution can realize the automatic opening or closing of the footrest 4, enabling the user to stand on one foot and use the other foot to toggle the support rod 4, which is safer, more convenient, and provides a better user experience. Parking state: After the vehicle stops stably, the driver presses the parking button. The driving actuator assembly reads the vehicle information including vehicle speed signal, brake signal, vehicle angle attitude, and support rod angle signal, and then makes an internal judgment of the input information by the driving mechanism. After meeting the parking conditions, corresponding instructions are given, and the rotating arm 9 of the execution module toggles the footrest 4. Under the combined action of the stretching spring 3, the footrest 4 is closed within a specified time, and the parking is completed. During the switching process between the above two states, the driver can normally use their foot to toggle the footrest 4 to open or close. Working state of the footrest 4 opening: After receiving legal information (after the vehicle stops stably, the driver presses the parking button, and the driving actuator reads the vehicle information including vehicle speed signal, brake signal, vehicle angle attitude, and support rod angle signal), the driving actuator assembly drives the rotating arm 9 to move. The rotating arm 9 drives the footrest 4 to rotate around a fixed rotation point to drive the footrest (flexible contact) to rotate together. During this period, the driving actuator assembly needs to overcome the reverse force of the stretching spring on the footrest 4. The footrest 4 reaches the rigid limit point of the vehicle body structure under the combined action of the stretching spring force. The driving actuator assembly internally monitors the angle sensor, and the rotating arm 9 moves in the reverse direction back to the initial position, preventing the driver from manually closing the footrest 4 from interfering with the driving actuator assembly and preventing manual operation in the case of no power. If there is an external structure blocking the movement during the above process, the actuator immediately detects the locked-rotor large current, and the internal control logic judges that the rotating arm returns to the initial position.
