Description

Technical Field

[0001] This utility model belongs to the field of scooter frames, specifically relating to an electric scooter frame with shock absorption function. Background Technology

[0002] The frame of an electric scooter is the supporting structure of the entire scooter, bearing the weight of the entire vehicle, the power system, and the rider's strength. It must have strength, stability, and the ability to adapt to different ground conditions.

[0003] Existing electric scooter frames typically have a housing for storing and installing batteries. During use, traditional electric scooter frames are often subjected to vibrations from the ground or surrounding objects. Since most existing electric scooter frames are rigid structures, vibrations are easily transmitted to the frame, causing the battery to resonate, which affects the battery's lifespan and safety.

[0004] Therefore, in order to address the problem that the existing electric scooter frames are not effective in shock absorption and protection of the battery, an electric scooter frame with shock absorption function is developed. By adding a battery buffer protection structure, a buffer limit structure, and bottom and top contact protection structures to the electric scooter frame, the impact of vibration on the battery inside the electric scooter frame during riding can be effectively reduced, and the safety of the battery inside the electric scooter frame can be improved. Utility Model Content

[0005] To overcome the problem that existing electric scooter frames are not effective at damping and protecting batteries.

[0006] The technical solution of this utility model is as follows: an electric scooter frame with shock absorption function, including a frame body and a battery box, and further including a buffer frame, a buffer housing, and a battery pack. The battery box is fixedly connected to the upper end of the frame body, and a first groove is formed in the lower inner wall of the battery box. The buffer frame is bolted to the inner wall of the battery box, and limit rods are fixedly connected to the four corner edges of the buffer frame. Two sets of first extension frames are symmetrically distributed vertically and vertically fixed to the left and right ends of the buffer frame. The upper and lower ends of the first extension frames are provided with mounting grooves, and shock absorbers are fixedly connected in the mounting grooves. The device has shock-absorbing springs fitted on the outer walls of both the upper and lower ends of the limiting rod. The buffer box is set inside the buffer frame. Slide grooves are opened through the four corner edges of the upper and lower ends of the buffer box. The slide grooves are adapted to the limiting rod. The battery pack is installed on the inner wall of the buffer box. The left and right ends of the buffer box are fixedly connected to the second extension frame symmetrically distributed front and back. The ends of the four shock absorbers near the second extension frame are respectively fixed to the upper and lower ends of the second extension frame. The lower buffer pad is fixedly connected in the first groove. The upper end of the battery box is bolted to the foot pedal. The lower end of the foot pedal is fixedly connected to the upper buffer pad.

[0007] Preferably, a top cover plate is bolted to the top of the buffer box, and handles are fixed to the left and right ends of the buffer box.

[0008] Preferably, the tail end of the shock-absorbing spring is fixed to the inner walls of the upper and lower ends of the buffer frame, and the head end of the shock-absorbing spring is fixed to the upper and lower ends of the buffer box.

[0009] Preferably, the battery box has a second groove at both the left and right ends, and the shock absorber, the first extension frame, the second extension frame and the handle are all located on the inner wall of the second groove.

[0010] Preferably, a front connecting cylinder is fixed to the left end of the frame body, a wheel connecting frame is fixed to the right end of the frame body, and a bottom protective plate is fixed to the lower end of the frame body.

[0012] Preferably, the lower end of the top cover plate is fitted to the upper end of the battery pack, and the outer wall of the buffer frame is fitted to the inner wall of the battery box.

[0013] The beneficial effects of this utility model are:

[0014] 1. The shock-absorbing spring on the limit rod, together with the shock absorber on the first extension frame, can perform up-and-down shock absorption on the left and right ends and the four corner edges of the buffer box. The shock absorber mainly absorbs the vibration, while the shock-absorbing spring assists the shock absorber in absorbing the buffer box, so as to evenly distribute the vibration received by the buffer box in all directions and protect the battery pack inside the buffer box to the greatest extent.

[0015] 2. The upper and lower buffer pads distributed at the top and bottom of the buffer box can support the battery box and prevent secondary vibrations caused by the buffer box hitting the bottom or top during lifting and buffering from damaging the battery pack inside the buffer box.

[0016] 3. By using the buffer frame and limit rod in conjunction with the buffer box and slide, the buffer box can slide up and down along the inner wall of the buffer frame to limit the buffer box and prevent it from falling out of the buffer frame or shifting during shock absorption.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-7This utility model provides an embodiment of an electric scooter frame with shock absorption function, including a frame body 1 and a battery box 3, as well as a buffer frame 4, a buffer box 5, and a battery pack 18. The battery box 3 is fixed to the upper end of the frame body 1. A first groove 9 is formed on the lower inner wall of the battery box 3. The buffer frame 4 is bolted to the inner wall of the battery box 3. Limiting rods 12 are fixed to the four corner edges of the buffer frame 4. Two sets of first extension frames 16 are symmetrically distributed vertically and vertically fixed to the left and right ends of the buffer frame 4. The upper and lower ends of the first extension frames 16 are provided with mounting grooves 15. Shock absorbers 13 are fixed in the mounting grooves 15. The upper and lower ends of the limiting rod 12 are fitted with shock-absorbing springs 14. The buffer box 5 is set inside the buffer frame 4. The upper and lower ends of the buffer box 5 are provided with sliding grooves 19 through the four corner edges. The sliding grooves 19 are adapted to the limiting rod 12. The inner wall of the buffer box 5 is equipped with a battery pack 18. The left and right ends of the buffer box 5 are fixed with second extension frames 20 distributed symmetrically in front and behind. The ends of four shock absorbers 13 near the second extension frames 20 are fixed to the upper and lower ends of the second extension frames 20 respectively. The lower buffer pad 11 is fixed inside the first groove 9. The upper end of the battery box 3 is bolted with a foot pedal 2. The lower end of the foot pedal 2 is fixed with an upper buffer pad 22.

[0027] The shock-absorbing spring 14 on the limiting rod 12, together with the shock absorber 13 on the first extension frame 16, can provide vertical shock absorption at the left and right ends and four corners of the buffer box 5. The shock absorber 13 provides the main shock absorption, while the shock-absorbing spring 14 assists the shock absorber 13 in buffering the buffer box 5, so as to evenly distribute the vibration received by the buffer box 5 in all directions, so as to protect the battery pack 18 inside the buffer box 5 to the greatest extent. The buffer frame 4 and the limiting rod 12, together with the buffer box 5 and the slide 19, can allow the buffer box 5 to slide up and down along the inner wall of the buffer frame 4, so as to limit the buffer box 5 and prevent it from falling off or displacing from the buffer frame 4 during shock absorption. The upper buffer pad 22 and the lower buffer pad 11 distributed at the upper and lower ends of the buffer box 5 can support the battery box 3 and prevent the secondary vibration generated by the buffer box 5 hitting the bottom or top during vertical shock absorption from damaging the battery pack 18 inside the buffer box 5.

[0028] Please see Figures 3-6In this embodiment, a top cover plate 17 is bolted to the upper end of the buffer box 5, and handles 21 are fixed to the left and right ends of the buffer box 5. During use, the handles 21 allow the user to easily remove the buffer box 5 and the buffer frame 4 bolted into the battery box 3 as a whole, facilitating subsequent maintenance of the shock-absorbing spring 14 and the shock absorber 13. The tail end of the shock-absorbing spring 14 is fixed to the inner walls of the upper and lower ends of the buffer frame 4, and the head end of the shock-absorbing spring 14 is fixed to the upper and lower ends of the buffer box 5. During use, the handles 21 allow the user to easily remove the buffer box 5 and the buffer frame 4 from the battery box 3 as a whole, facilitating subsequent maintenance of the shock-absorbing spring 14 and the shock absorber 13. The shock-absorbing springs 14 placed at the four corners of the upper and lower ends of the buffer box 5 can effectively assist the buffer box 5 in lifting and cushioning. The battery box 3 has a second groove 10 at both ends. The shock absorber 13, the first extension frame 16, the second extension frame 20 and the handle 21 are all located on the inner wall of the second groove 10. In use, the second groove 10 can provide lifting space for the first extension frame 16, the second extension frame 20 and the handle 21 that lift and cushion with the buffer box 5, so as to avoid them from colliding with the inner wall of the battery box 3.

[0029] Please see Figure 3 In this embodiment, a front connecting tube 7 is fixedly connected to the left end of the frame body 1, a wheel connecting frame 8 is fixedly connected to the right end of the frame body 1, and a bottom protective plate 6 is fixedly connected to the lower end of the frame body 1. In use, the bottom protective plate 6 can provide additional protection for the lower end of the battery box 3 to prevent sharp foreign objects from easily piercing the battery box 3 and the buffer box 5 and causing damage to the battery pack 18.

[0030] Please see Figures 3-7 In this embodiment, the upper end of the lower buffer pad 11 is attached to the lower end of the buffer box 5, and the lower end of the upper buffer pad 22 is attached to the upper end of the top cover plate 17. In use, the lower buffer pad 11 and the upper buffer pad 22 can provide certain buffering and shock absorption for the upper and lower ends of the buffer box 5. The lower end of the top cover plate 17 is attached to the upper end of the battery pack 18, and the outer wall of the buffer frame 4 is attached to the inner wall of the battery box 3. In use, the top cover plate 17 can seal the upper opening of the buffer box 5 to prevent foreign objects from entering the buffer box 5 and affecting the normal use of the battery pack 18.

[0031] Before use, install the front part of the electric scooter into the front connecting tube 7 and install the wheels onto the wheel connecting frame 8 to complete the assembly of the electric scooter.

[0032] During the use of the electric scooter, the vibration generated by the scooter will cause the battery pack 18 installed in the battery box 3 to resonate. The buffer box 5, which is limited and installed in the buffer frame 4, will slide up and down along the outer wall of the limiting rod 12 due to the vibration. The shock absorber 13 and the shock-absorbing spring 14 can buffer and dampen the left and right ends and four corners of the buffer box 5, so as to evenly distribute the vibration received by the buffer box 5 in all directions. The upper buffer pad 22 and the lower buffer pad 11 protect the battery box 3 from the secondary vibration generated by the buffer box 5 hitting the bottom or top during the lifting and buffering, so as to prevent the battery pack 18 inside the buffer box 5 from being damaged by vibration.

[0033] Through the above steps, the shock-absorbing spring 14, in conjunction with the shock absorber 13, can provide vertical shock absorption at the left and right ends and the four corners of the buffer box 5, so as to evenly distribute the vibration received by the buffer box 5 in all directions and protect the battery pack 18 inside the buffer box 5 to the greatest extent. The upper buffer pad 22 and the lower buffer pad 11 distributed at the upper and lower ends of the buffer box 5 can support the battery box 3 and prevent the secondary vibration generated by the buffer box 5 hitting the bottom or top during vertical shock absorption from damaging the battery pack 18 inside the buffer box 5. This solves the problem that the existing electric scooter frame does not provide good shock absorption and protection for the battery.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
