Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically to an anti-theft structure for a kettle-shaped battery. Background Technology

[0002] Electric bicycles are mechatronic personal transportation vehicles that use batteries as auxiliary power and are based on ordinary bicycles, equipped with motors, controllers, power batteries, throttles, and other control components, as well as display systems. In recent years, with the continuous improvement of people's living standards, electric-assisted bicycles have become increasingly popular due to their convenience, comfort, safety, energy saving, and environmental friendliness.

[0003] However, electric bicycles still have many shortcomings in actual use. For example, the battery box is mounted on the battery tube body and locked by a single mechanical lock. However, using a single mechanical lock to lock the battery box may pose a risk of accidental locking. For example, when riding on a bumpy road, the battery box may fall off the battery tube body, which may pose a certain safety hazard. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides an anti-theft structure for a kettle-shaped battery, which combines a locking tongue and a buckle structure for double locking. This structure can not only securely install the battery box, but also prevent theft.

[0005] To achieve the above objectives, an anti-theft structure for a kettle-shaped battery is designed, comprising a battery box, a spring lock, a battery box frame, and a discharge connector. The key features are: one end of the battery box is connected to the spring lock, the other end of the battery box is connected to the housing via the discharge connector, and the bottom of the battery box is provided with a battery box frame; the side of the spring lock is connected to the battery box via a pin, and the driving end of the spring lock is connected to a locking tongue.

[0006] One end of the battery box is provided with a spring lock groove, and a spring lock is embedded in the spring lock groove; a pin passes through the bottom of the battery box and is connected to the spring lock; a locking tongue moving groove is provided on the battery box below the pin, and a decorative cover is provided on the upper part of the locking tongue moving groove, and the decorative cover is connected to the bottom of the battery box by several screws.

[0007] The latch has an L-shaped structure, with one end connected to the spring lock by a thread, and the other end located in the latch movement groove on the battery box.

[0008] The battery box frame is a panel structure, and it is fixed to the vehicle frame with several screws. One end of the battery box frame is connected to the pressing handle by a torsion spring and a pin, and the other end of the battery box frame is connected to the discharge connector housing by several screws.

[0009] The battery box frame is equipped with a slide rail, which has an arc-shaped track groove structure; a locking tongue fixing groove is provided at the top of the slide rail.

[0010] The decorative cover has a groove on its lower side that matches the slide rail structure of the battery box holder; the battery box on one side of the decorative cover has a buckle groove.

[0011] The pressing handle is provided with a snap-fit ​​protrusion that matches the snap-fit ​​groove structure of the battery box.

[0012] The lower inner side of the discharge connector housing is connected to the other end of the battery box frame by several screws, and the discharge connector is connected to the outer side of the discharge connector housing.

[0013] The battery box contains several lithium battery packs.

[0014] Compared with the prior art, this utility model provides an anti-theft structure for a kettle-shaped battery, which combines a locking tongue and a buckle structure to achieve a double locking structure, which can not only fix the battery box in place, but also play a role in preventing theft.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figures 1 to 6As shown, one end of the battery box 10 is connected to the spring lock 2, and the other end of the battery box 10 is connected to the housing 8 and the discharge connector 9 through the discharge connector. The bottom of the battery box 10 is provided with a battery box frame 7. The side of the spring lock 2 is connected to the battery box 10 through the pin 3, and the driving end of the spring lock 2 is connected to the locking tongue 6.

[0024] One end of the battery box 10 is provided with a spring lock groove, and a spring lock 2 is embedded in the spring lock groove; a pin 3 passes through the bottom of the battery box 10 and is connected to the spring lock 2; a locking tongue moving groove is provided on the battery box 10 located below the pin 3, and a decorative cover 4 is provided on the upper part of the locking tongue moving groove, and the decorative cover 4 is connected to the bottom of the battery box 10 by several screws.

[0025] The latch 6 has an L-shaped structure. One end of the latch 6 is connected to the spring lock 2 by a thread, and the other end of the latch 6 is located in the latch moving groove on the battery box 10.

[0026] The battery box frame 7 is a panel structure. The battery box frame 7 is fixedly connected to the vehicle frame with several screws. One end of the battery box frame 7 is connected to the pressing handle 5 by a torsion spring 13 and a pin 14. The other end of the battery box frame 7 is connected to the discharge connector housing 8 by several screws.

[0027] The battery box holder 7 is equipped with a slide rail 16, which has an arc-shaped track groove structure; a locking tongue fixing groove 15 is provided at the top of the slide rail 16.

[0028] The lower side of the decorative cover 4 is provided with a slide groove 17 that matches the slide rail 16 structure of the battery box holder 7; the battery box 10 located on one side of the decorative cover 4 is provided with a buckle groove 11.

[0029] The pressing handle 5 is provided with a snap-fit ​​protrusion 12 that matches the snap-fit ​​groove 11 structure of the battery box 10.

[0030] The lower inner side of the discharge connector connection housing 8 is connected to the other end of the battery box frame 7 by several screws, and the outer side of the discharge connector connection housing 8 is connected to the discharge connector 9.

[0031] The battery box 10 contains several lithium battery packs.

[0032] In this utility model structure, the locking tongue 6 and the spring lock 2 are connected by threads, and the pressing handle 5 is connected to the battery box frame 7 through the torsion spring 13 and the pin 14.

[0033] The locking principle of this utility model is as follows: After the battery box 10 is inserted into the slide rail 16 of the battery box holder 7, it rotates counterclockwise (that is, the slide groove 17 on the battery box 10 cooperates with the slide rail 16 on the battery box holder 7. Due to the arc design of the slide rail 16, it does not translate, but rotates the battery box 10 at a certain arc angle, so that the slide rail 16 matches the slide groove 17). Pressing the handle 5 compresses the latch protrusion 12 on the battery box holder 7, and the latch protrusion 12 on the battery box holder 7 enters the latch groove 11 on the battery box 10 under the action of the torsion spring 13, thus completing the installation of the battery box 10. At the same time, pressing the button of the spring lock 2 causes the latch 6 to move axially (i.e., move downwards), and the end of the latch 6 enters the latch fixing groove 15 on the battery box holder 7, thus achieving the anti-theft function.

[0034] The unlocking principle of this utility model is as follows: Insert the key 1 and rotate it clockwise. Due to the reset principle of the spring lock 2, the latch 6 moves in the opposite direction (i.e., moves upward). The end of the latch 6 disengages from the latch fixing groove 15 on the battery box frame 7. Then, press the handle 5. The buckle protrusion 12 on the battery box frame 7 disengages from the buckle groove 11 on the battery box 10. Rotating the battery box 10 clockwise will allow the battery box 10 to be removed.
