Description

Technical Field

[0001] This utility model relates to the field of electric vehicle batteries, specifically to an electric vehicle battery with anti-theft function and an electric vehicle. Background Technology

[0002] With the increasing popularity of electric vehicles, the problem of electric vehicle battery theft is becoming more and more serious. At present, most electric vehicles and batteries with anti-theft functions on the market use traditional anti-theft methods such as mechanical locks and GPS positioning. Mechanical locks are easy to be forcibly broken and have poor anti-theft effect. GPS positioning relies on the network and can only be tracked after the fact, and cannot directly prevent theft from the structure.

[0003] Existing battery anti-theft structures suffer from complex installation and high costs, while electric vehicle anti-theft designs often focus on locking the entire vehicle, providing insufficient protection for the battery. In addition, some anti-theft structures that incorporate smart components suffer from poor stability and susceptibility to electromagnetic interference, making it difficult to effectively protect the safety of the battery and the vehicle. Therefore, we propose an electric vehicle battery and electric vehicle with anti-theft functions. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 An anti-theft battery for electric vehicles and an electric vehicle are disclosed, comprising an electric vehicle 1, a battery mounting box 2, and a cover plate 3. The battery mounting box 2 is mounted on the support frame of the electric vehicle 1. The cover plate 3 is mounted on the open end of the battery mounting box 2. A battery 4 is placed inside the battery mounting box 2. A mounting frame 13 is fixedly connected to one side of the cover plate 3.

The two-way locking structure is located inside the mounting frame 13. Two sets of symmetrical clamping structures about the battery mounting box 2 are provided on both sides where the battery mounting box 2 is inserted into the mounting frame 13.

[0026] Furthermore, the bidirectional locking structure includes a tubular electromagnet 7, a support plate 8, a first insertion rod 9, and a second insertion rod 10. The tubular electromagnet 7 is fixedly connected to the middle of the side of the cover plate 3 connected to the mounting frame 13. The two ends of the tubular electromagnet 7 face the two sides of the cover plate 3. The armature end of the tubular electromagnet 7 is fixedly connected to the support plate 8. Multiple first insertion rods 9 distributed in a straight line are fixedly connected to the other side of the support plate 8. The core end of the tubular electromagnet 7 is fixedly connected to another support plate 8.

Insertion rod 9 passes through the through hole 11. The through hole 11 is used to connect insertion rod 9 and insertion rod 2.

[0028] Furthermore, the bidirectional locking structure also includes telescopic grooves 14, spring 15, and telescopic rod 5. Multiple telescopic grooves 14 are provided on the inner wall of the battery mounting box 2 opposite to the insertion rod 10, arranged in a straight line. Spring 15 is fixedly connected to the opposite side of each telescopic groove 14 opening, and telescopic rod 5 is fixedly connected to the other end of each spring 15. The telescopic rod 5 is inserted into the through hole 11 on one side of the mounting frame 13. The telescopic groove 14 is used to install spring 15 and telescopic rod 5. Spring 15 drives the telescopic rod 5 to extend out of the telescopic groove 14. 4. When the tubular electromagnet 7 is de-energized, the iron core of the tubular electromagnet 7 retracts, causing the second insertion rod 10 to retract away from the telescopic rod 5. Under the elastic force of the first spring 15, the telescopic rod 5 is in the through hole 11, thus locking the mounting frame 13 and the battery mounting box 2. When the tubular electromagnet 7 is energized, the iron core of the tubular electromagnet 7 extends, causing the second insertion rod 10 to extend towards the telescopic rod 5. The telescopic rod 5 is retracted into the telescopic groove 14 under the pressure of the second insertion rod 10, making it convenient to remove the cover plate 3 and the mounting frame 13.

[0029] Furthermore, the two-way locking structure also includes slots 16. Multiple slots 16 are provided on the inner wall of the battery mounting box 2 opposite to the insertion rod 9, arranged in a straight line. The end of the insertion rod 9 away from the support plate 8 is inserted into the slot 16. The slot 16 is used to place the insertion rod 9. When the tubular electromagnet 7 is de-energized, the armature of the tubular electromagnet 7 extends and moves, driving the insertion rod 9 through the through hole 11 and inserting it into the slot 16, thereby locking the mounting frame 13 and the battery mounting box 2. When the tubular electromagnet 7 is energized, the armature of the tubular electromagnet 7 retracts and moves, driving the insertion rod 9 back into the through hole 11, making it convenient to remove the cover plate 3 and the mounting frame 13.

[0030] Furthermore, the clamping structure includes a strip groove 17, a second spring 18, and a bending plate 6. The inner walls of both sides of the battery mounting box 2, which do not have the telescopic groove 14 and slot 16, are provided with strip grooves 17. Multiple second springs 18 distributed in a straight line are fixedly connected to the opposite side of the opening of the strip groove 17. A bending plate 6 is fixedly connected to the other end of the second spring 18. The inner walls of both sides of the bending plate 6 are fixedly connected to the second spring 18. The strip groove 17 is used to install the second spring 18 and the bending plate 6. The second spring 18 drives the bending plate 6 to extend out of the strip groove 17.

[0031] Furthermore, the clamping structure also includes a triangular groove 12. Triangular grooves 12 are provided on both sides of the mounting frame 13 opposite to the bending plate 6. The bending plate 6 is clamped to the triangular groove 12. The triangular groove 12 is used to clamp with the strip groove 17. The slope of the bending plate 6 makes it easy for the bending plate 6 to be retracted into the strip groove 17 under force, but it also has a certain clamping ability.

At the same time, the iron core retracts, and the second insertion rod 10 retracts away from the side of the telescopic rod 5. The telescopic rod 5 extends out of the telescopic groove 14 under the elastic force of the first spring 15 and inserts into the through hole 11 on one side of the mounting frame 13. Simultaneously, the second spring 18 in the strip grooves 17 on both sides of the battery mounting box 2 drives the bending plate 6 to extend and engage with the triangular grooves 12 on both sides of the mounting frame 13. At this time, the first insertion rod 9, the telescopic rod 5, and the bending plate 6 work together to tightly lock the mounting frame 13 and the battery mounting box 2, thereby preventing the cover plate from being closed. 3 is easily opened, protecting battery 4 from theft. When it is necessary to open cover 3 to remove battery 4, the tubular electromagnet 7 is energized, the iron core extends, and drives the second insertion rod 10 to extend to the side of the telescopic rod 5. The second insertion rod 10 squeezes the telescopic rod 5, causing it to retract into the telescopic groove 14. At the same time, the armature retracts, driving the first insertion rod 9 to retract into the through hole 11. At this time, the first insertion rod 9 and the telescopic rod 5 no longer restrict the mounting frame 13. The cover 3 is pulled outward, and the triangular grooves 12 on both sides of the mounting frame 13 apply pressure to the slope of the bending plate 6, causing the bending plate 6 to retract into the strip groove 17, thereby releasing the locking of the clamping structure. The cover 3 and the mounting frame 13 can then be removed, and the battery 4 can be easily taken out.
