Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle technology, specifically to a scooter with a stable rear wheel connecting seat structure. Background Technology
[0002] Electric scooters, as a new type of short-distance transportation tool, are increasingly popular due to their small size and ease of operation. Electric scooters typically include a control stick, a front wheel, foot pedals, a rear shock absorber spring, and a rear wheel. The rear wheel and the rear end of the foot pedals are connected. The upper end of the control stick forms the front of the scooter, and the lower end of the control stick is indirectly connected to the front wheel. The control stick is also indirectly connected to the front end of the foot pedals.
[0003] Existing foot pedals are typically mounted on the frame. To secure them to the rear wheel, two connecting tubes extend rearward from both sides of the frame. Connecting sheet metal parts are welded to the upper surfaces of these tubes. These connecting sheet metal parts have two chain shock absorber connectors that mate with the rear shock absorber springs. These connectors are positioned on either side of the springs and are hinged to them. To improve shock absorption, the connecting tubes are angled upwards, not horizontally relative to the frame. While this achieves shock absorption, over time, the reinforcing structure causes the rear shock absorber springs to push upwards against the connecting sheet metal parts, leading to deformation between the connecting tubes and the frame. This negatively impacts the scooter's shock absorption, affecting the user experience and hindering product competitiveness. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a scooter with a stable rear wheel connection seat structure, which solves the problem that the rear wheel connection structure of existing scooters is prone to deformation.
[0005] This utility model discloses a scooter with a stable rear wheel connecting seat structure, including a control lever, a front wheel assembly, a pedal frame, a rear shock absorber spring, and a rear wheel assembly. The pedal frame includes a frame body, a connecting seat, and foot pedals. Two rear mounting tubes extend rearward from both sides of the rear end of the frame body, and the ends of the two rear mounting tubes are connected and integrally formed.

[0018] like Figure 1 and Figure 2 As shown, this utility model discloses a scooter with a stable rear wheel connecting seat 7 structure, including a control lever 1, a front wheel assembly, a pedal frame, a rear shock absorber spring 9, and a rear wheel assembly. The pedal frame includes a frame body 6, a connecting seat 7, and pedals 8. Two rear mounting tubes 61 extend rearward from both sides of the rear end of the frame body 6, and the ends of the two rear mounting tubes 61 are connected and integrally formed. A reinforcing cross tube 62 is provided near one end of the two rear mounting tubes 61 near the frame body 6. The two reinforcing cross tubes 62 are connected to each other. The ends are respectively connected to two rear mounting tubes 61. The two ends of the connecting seat 7 are respectively welded to the connecting ends of the two rear mounting tubes 61 and the reinforcing horizontal tube 62. The upper end of the rear shock absorber spring 9 is hinged to the end of the connecting seat 7 away from the frame body 6. The rear wheel assembly 10 includes a rear swing arm 101 and a rear wheel body 102. One end of the rear swing arm 101 is hinged to the other end of the connecting seat 7. The other end of the rear swing arm 101 is rotatably connected to the rear wheel body 102. The lower end of the rear shock absorber spring 9 is hinged to the rear swing arm 101.
[0019] By connecting the ends of the two rear mounting tubes 61 in one piece and cooperating with the reinforcing cross tube 62, the two rear mounting tubes 61 form a frame, effectively enhancing the overall strength of the two rear mounting tubes 61. By welding the two ends of the connecting seat 7 to the connecting ends of the two rear mounting tubes 61 and the reinforcing cross tube 62 respectively, the force applied by the rear shock absorber spring 9 can be effectively distributed across the entire frame of the rear mounting tubes 61, reducing the maximum force applied by the rear shock absorber spring 9 to one point, improving the strength of the position between the rear mounting tubes 61 and the frame body 6, avoiding deformation, improving the user experience and the competitiveness of the product.
[0020] The connecting seat 7 includes a connecting horizontal plate 71 and connecting vertical plates 72 disposed on both sides of the connecting horizontal plate 71. The connecting vertical plate 72 is provided with hinge holes 721 that cooperate with the rear shock absorber spring 9.
[0021] By setting up the connecting plate 71, the problem of low overall strength caused by the existing method of using two connecting seats 7 to hinge the upper sides of the rear shock absorber spring 9 is effectively solved.
[0022] The connecting horizontal plate 71 and the connecting vertical plate 72 are integrally formed. This integral forming can make the force on the two connecting vertical plates 72 more even to a certain extent, avoid deformation, and further transfer the force applied by the rear shock absorber spring 9 to the rear mounting tube 61 frame.
[0023] The two ends of the reinforcing horizontal tube 62 are welded and fixed to the two rear mounting tubes 61. This setting can improve the stability of the position between the reinforcing horizontal tube 62 and the rear mounting tubes 61.
[0024] The rear swingarm 101 includes two rear swingarm plates and a connecting shaft disposed between the two rear swingarm plates, with the lower end of the shock-absorbing spring hinged to the connecting shaft.
[0025] The scooter with a stable rear wheel connection seat 7 structure also includes a front shock absorber spring 3. The front wheel assembly is equipped with a front rocker arm 2, a front extension arm 4, and a front wheel body 5. The front extension arm 4 is rotatably connected to the pedal frame, while the control lever 1 is fixedly connected to the front extension arm 4. The front rocker arm 2 is hinged to the front extension arm 4. The lower end of the front shock absorber spring 3 is hinged to the front rocker arm 2, the upper end of the front shock absorber spring 3 is hinged to the front extension arm 4, and the front wheel body 5 is hinged to the front extension arm 4.
[0026] As can be seen from the above, the beneficial effects of this utility model are: by adopting its structure, it can effectively solve the problem of easy deformation of the rear wheel connection structure of the scooter in the prior art. Through the integral molding of the ends of the two rear mounting tubes 61 and the cooperation of the reinforcing horizontal tube 62, the two rear mounting tubes 61 form a frame, which effectively enhances the overall strength of the two rear mounting tubes 61. By welding the two ends of the connecting seat 7 to the connecting ends of the two rear mounting tubes 61 and the reinforcing horizontal tube 62 respectively, the force applied by the rear shock absorber spring 9 can be effectively distributed to the entire frame of the rear mounting tube 61, reducing the maximum force applied by the rear shock absorber spring 9 to one point, improving the strength of the position between the rear mounting tube 61 and the frame body 6, avoiding deformation, improving the user experience and the competitiveness of the product.
