Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to an electric vehicle with a charging box and rear seat fixing buckle structure. Background Technology

[0002] Electric bicycles, also known as "electric vehicles," are pure electric motor vehicles powered by batteries and driven by electric motors (DC, AC, series, and separately excited). In recent years, they have become very popular in my country. Many electric bicycles are designed with the battery pack placed in the battery compartment in the rear seat. When the electric bicycle's power is depleted, the battery pack can be removed and replaced with a fully charged one to ensure continued use.

[0003] In existing technology, after the battery pack is placed behind the battery tube, a cover is usually installed at the top of the battery tube. One end of the cover is hinged to the battery tube, and the other end has a flexible latch that engages with a slot on the battery tube. This allows the cover to be closed to secure the battery pack and prevent safety risks caused by the battery pack moving around inside the battery tube. However, if the battery is not removed, the battery cover remains loose, making the user feel unreliable and significantly reducing the safety and reliability of the electric vehicle.

[0004] However, since the cover can be opened and closed by simply lifting or pressing, it is prone to loosening or even opening accidentally when riding an electric vehicle on very bumpy roads. This can cause the battery pack to shake during use, posing a significant safety hazard. Therefore, we propose an electric vehicle with a charging box and rear seat fixing clip structure. Utility Model Content

[0005] The purpose of this utility model is to provide an electric vehicle with a rear seat fixing buckle structure for a charging box, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric vehicle with a charging box and a rear seat fixing buckle structure, comprising: an electric vehicle body and a rear seat box, a battery tube is provided inside the rear seat box, a battery pack is provided inside the battery tube, a positioning cover plate is hinged to the top of one end of the battery tube, a pressure plate is installed on the end of the positioning cover plate near the battery pack, a handle is connected to the other end of the positioning cover plate, and a protective pad is provided on the surface of the pressure plate.

[0007] The positioning cover plate has a toggle groove at the top near the handle. A toggle plate is slidably installed inside the toggle groove. A reinforcing spring is installed at one end of the toggle plate near the handle. A connecting rod is connected to the bottom end of the toggle plate. A fixing block is installed at one end of the connecting rod.

[0008] A fixing groove is provided on the surface of the battery tube near the fixing block. One end of the fixing block passes through the positioning cover plate and is inserted into the fixing groove, and the other end of the fixing block is connected to a fixing spring.

[0009] Preferably, one end of the pressure plate is fixedly installed on the positioning cover plate, the other end of the pressure plate is fixedly connected to the protective pad, and a sealing ring is fitted on the outer wall of the end of the pressure plate near the positioning cover plate.

[0010] Preferably, the actuating plate is T-shaped, with its bottom end slidably connected to the inner wall of the actuating groove, its top end extending out of the actuating groove, and a reinforcing spring located inside the actuating groove. One end of the reinforcing spring is fixedly installed on the actuating plate, and the other end of the reinforcing spring is fixedly installed on the inner side wall of the actuating groove.

[0011] Preferably, the top end of the connecting rod is fixedly connected to the actuating plate, the bottom end of the actuating groove is connected to the connecting groove, and the outer wall of the connecting rod is slidably connected to the inner wall of the connecting groove.

[0012] Preferably, the fixing blocks are T-shaped and two are symmetrically arranged. The two ends of the connecting groove near the two fixing blocks are connected to the limiting grooves. The two ends of the connecting rod are slidably inserted into the corresponding limiting grooves and fixedly connected to the fixing blocks.

[0013] Preferably, one end of each of the two fixing blocks is slidably installed in an adjacent limiting groove, the bottom of the other end of each of the two fixing blocks is an arc surface, and two fixing springs are connected to the end of each of the two fixing blocks near the connecting rod. One end of each of the two adjacent fixing springs is fixedly installed at the edge of one end of the fixing block, and the other end of each of the two adjacent fixing springs is fixedly installed on the inner wall of the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a pressure plate at the bottom of the positioning cover to firmly hold the top of the battery pack in place. A protective pad reduces hard contact between the pressure plate and the battery pack. The elasticity of the fixing spring allows the fixing block to insert into the fixing groove, thus securing the positioning cover. Through the connection of the fixing block, connecting rod, and actuating plate, the actuating plate needs to be moved towards the handle to lift the handle and open the positioning cover. A reinforcing spring at one end of the actuating plate prevents it from shifting a considerable distance due to bumps. Therefore, when driving an electric vehicle on very bumpy roads, the positioning cover is less likely to loosen or even open accidentally, preventing the battery pack from shaking and posing a significant safety hazard.

They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: an electric vehicle with a charging box and a rear seat fixing buckle structure, including: an electric vehicle body 1 and a rear seat box 2. The rear seat box 2 is provided with a battery cylinder 4, and the battery cylinder 4 is provided with a battery pack 3. A positioning cover plate 5 is hinged to the top of one end of the battery cylinder 4. A pressure plate 6 is installed on the end of the positioning cover plate 5 near the battery pack 3. A handle 9 is connected to the other end of the positioning cover plate 5. A protective pad 7 is provided on the surface of the pressure plate 6. One end of the pressure plate 6 is fixedly installed on the positioning cover plate 5, and the other end of the pressure plate 6 is fixedly connected to the protective pad 7. A sealing ring 8 is sleeved on the outer wall of the end of the pressure plate 6 near the positioning cover plate 5, which can improve the sealing performance of the connection between the positioning cover plate 5 and the battery cylinder 4, making it difficult for water stains to enter the battery cylinder 4.

[0025] A toggle groove 17 is provided on the top of the positioning cover 5 near the handle 9. A toggle plate 16 is slidably installed inside the toggle groove 17. A reinforcing spring 18 is installed on one end of the toggle plate 16 near the handle 9. A connecting rod 14 is connected to the bottom end of the toggle plate 16, and a fixing block 10 is installed on one end of the connecting rod 14. The toggle plate 16 is T-shaped. The bottom end of the toggle plate 16 is slidably connected to the inner wall of the toggle groove 17, and the top end of the toggle plate 16 extends out of the toggle groove 17. The reinforcing spring 18 is located inside the toggle groove 17. One end of the reinforcing spring 18 is fixedly installed on the toggle plate 16, and the other end of the reinforcing spring 18 is fixedly installed on the inner side wall of the toggle groove 17. When the positioning cover 5 is opened and the toggle plate 16 is moved towards the handle 9, the reinforcing spring 18 is compressed. The top end of the connecting rod 14 is fixedly connected to the toggle plate 16, and the bottom end of the toggle groove 17 is connected to a connecting groove 15. The outer wall of the connecting rod 14 is slidably connected to the inner wall of the connecting groove 15.

[0026] A fixing groove 11 is formed on the surface of the battery tube 4 near the fixing block 10. One end of the fixing block 10 passes through the positioning cover plate 5 and is inserted into the fixing groove 11. The other end of the fixing block 10 is connected to a fixing spring 13. The fixing blocks 10 are T-shaped and there are two symmetrically arranged. The connecting groove 15 is connected to the limiting groove 12 at both ends of the two fixing blocks 10. Both ends of the connecting rod 14 are slidably inserted into the corresponding limiting groove 12 and fixedly connected to the fixing block 10. In order to improve the stability of the fixing block 10, the fixing spring 13 and the limiting groove 12 can be provided with a damping effect so that the fixing spring 13 is not easy to shake accidentally. One end of the two fixing blocks 10 is slidably installed in the adjacent limiting groove 12. The bottom of the other end of the two fixing blocks 10 is curved. Two fixing springs 13 are connected to the end of the two fixing blocks 10 near the connecting rod 14. One end of the two adjacent fixing springs 13 is fixedly installed at the edge of one end of the fixing block 10. The other end of the two adjacent fixing springs 13 is fixedly installed on the inner wall of the limiting groove 12.

[0027] When this device is working, the pressure plate 6 at the bottom of the positioning cover 5 can press and limit the top of the battery pack 3. The protective pad 7 on the surface of the pressure plate 6 can reduce the hard contact between the pressure plate 6 and the battery pack 3. The elastic action of the fixing spring 13 allows the fixing block 10 to be inserted into the fixing groove 11, which is convenient for fixing the positioning cover 5 when it is closed. Through the connection of the fixing block 10, the connecting rod 14 and the actuating plate 16, the actuating plate 16 needs to be moved towards the handle 9 to lift the handle 9 and open the positioning cover 5. The reinforcing spring 13 at one end of the actuating plate 16 makes it difficult for the actuating plate 16 to move a long distance due to bumps. Therefore, when the electric vehicle is driven on a very bumpy road, the positioning cover 5 is less likely to loosen or even open accidentally, so as to prevent the battery pack 3 from shaking during use and causing a great safety hazard.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
