Description

Technical Field

[0001] The present invention relates to the technical field of potentiometer adjustment, and particularly to a potentiometer adjustment mechanism for a speed control device of a scooter. Background Art

[0002] In the field of scooters, the speed control device is crucial for the safe and stable operation of the vehicle and the driving experience of users. There are many drawbacks in the potentiometer adjustment method of traditional scooter speed control devices. In the past, most of them used the method of directly rotating the handlebar to adjust the potentiometer to achieve the speed control function of the scooter. In actual use, users need to constantly hold the handlebar tightly with their hands and rotate it. In some complex road conditions, frequent operation of the handlebar will not only distract the driver's attention but also may cause operation errors due to hand fatigue, affecting driving safety. For example, in narrow streets or crowded areas, the driver has to pay attention to the surrounding environment and operate the handlebar to adjust the speed at the same time, which is easy to get flustered. When the driver needs to brake urgently, only relying on the brake operation, the potentiometer will not automatically return to its original position, and the power of the vehicle cannot be cut off in time. This may result in the situation that the vehicle still has power output when braking, leading to an extended braking distance and increasing the risk of collision, threatening the safety of the driver and pedestrians. For example, when encountering a sudden obstacle and needing to brake urgently, the vehicle cannot stop quickly, which is easy to cause accidents.

[0003] With the continuous improvement of people's requirements for the safety and use experience of scooters, it is urgent to develop a potentiometer adjustment mechanism for a more safe, convenient and accurate scooter speed control device.

The periphery of the support 1 26 is provided with a torsion spring 25, and one end of the torsion spring 25 is connected to the electric door handle 13, and the other end of the torsion spring 25 is connected to the base plate 1.

[0028] The outer surface of the bracket 2 5 is provided with a guide sleeve 6, and a separation rod 7 is slidably connected inside the guide sleeve 6. A collar 28 is fixedly connected to one end of the separation rod 7, and a linkage rod 24 is movably connected to the other end of the separation rod 7. The other end of the linkage rod 24 is fixedly connected to the brake handle 12. A sliding sleeve is provided on the outer surface of the bracket 2 5, and the bracket 2 5 is slidably connected to the clutch guide rod 10 through the sliding sleeve.

[0029] The outer surface of the clutch guide rod 10 is fixedly connected with a retaining ring 16, and the clutch guide rod 10 passes through the inside of the collar 28, and the collar 28 and the retaining ring 16 abut against each other.

[0030] Working principle: When the electric switch handle 13 is pulled, the electric switch handle 13 rotates around the pillar 1 26, driving the arc push plate 22 fixed at one end thereof to move. The periphery of the pillar 1 26 is provided with a torsion spring 25, which maintains the initial position of the electric switch handle 13 under normal conditions. The arc push plate 22 pushes the rack 21 abutting against it, and the rack 21 slides in the rack mounting groove 19. The rack mounting groove 19 is provided with a reaction spring 1 20, which can reset the rack 21 when it loses thrust. The rack 21 meshes with the sector gear 29, and the linear motion of the rack 21 drives the sector gear 29 to rotate.

[0031] The sector gear 29 is fixed on the transmission guide rod 11, so the transmission guide rod 11 rotates accordingly. The guide post 31 on the outer surface of the transmission guide rod 11 is in the straight-line segment of the self-rotating guide groove 17 of the clutch guide rod 10, thereby driving the clutch guide rod 10 to rotate synchronously. The sleeve teeth 15 at one end of the clutch guide rod 10 and the tooth cylinder 14 of the rotary joint end part 9 of the output rotary handle of the self-resetting potentiometer 3 are disengaged from the meshing state at this time. Therefore, the rotary joint 9 rotates synchronously, and further rotates the self-resetting potentiometer 3, changing the resistance value of the potentiometer, and realizing the speed regulation of the scooter.

[0032] When the brake handle 12 is operated, the operation of the hand at this time is to discard the throttle handle 13 and grasp the brake. The brake handle 12 drives the separation pull rod 7 to slide in the guide sleeve 6 through the linkage rod 24. The collar 28 at one end of the separation pull rod 7 abuts against the retaining ring 16 on the clutch guide rod 10. As the separation pull rod 7 slides, the collar 28 pushes the retaining ring 16, causing the clutch guide rod 10 to slide away from the rotary joint 9. The sleeve teeth 15 are disengaged from the tooth cylinder 14, the reaction spring II 32 is compressed, and the guide post 31 moves along the self-rotating guide groove 17. Affected by the self-rotating guide groove 17, the clutch guide rod 10 deflects within a small range. The purpose is to facilitate the successful tooth engagement between the sleeve teeth 15 and the tooth cylinder 14 after releasing the brake subsequently, and realize re-engagement. The self-resetting potentiometer 3 loses the external force and automatically returns to its original position under its own reset mechanism, and the resistance value returns to the initial state, realizing automatic power-off when braking and improving driving safety.

However, the present invention is not limited to the above embodiments.
