Description
Technical Field
[0001] This utility model relates to the field of battery anti-theft technology, specifically an anti-theft structure for a lithium battery. Background Technology
[0002] With the development of the truck industry, lithium batteries are being used more and more widely in the truck field. However, as a high-value component, lithium batteries are at risk of being stolen, which not only brings economic losses to truck owners, but may also affect the normal use and safety of the vehicle.
[0003] Existing lithium battery anti-theft measures mostly rely on physical locks or simple alarm devices. However, the locks themselves can be damaged or cracked. Although the alarm device can sound an alarm when the lithium battery is moved or damaged, it will not work properly and will lose its anti-theft function if the circuit is cut off. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-theft structure for lithium batteries to solve the problems mentioned in the background. This utility model has a novel structure that triggers the anti-theft mechanism by cutting off the circuit power. The cooperation between the pin and the slot can quickly and firmly fix the lithium battery body, effectively preventing theft and greatly improving the anti-theft security of lithium batteries. Utilizing common components such as electromagnets and springs, through a reasonable structural layout and linkage design, it achieves the function of automatic locking after theft and preventing easy reset. Since the conductive copper sheet has disconnected the connection between the two sets of conductive clips, even if the thief tries to reconnect the power, the electromagnet cannot work, the connecting block cannot reset, and the pin always remains in the slot, continuously fixing the lithium battery body and preventing it from being stolen.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an anti-theft structure for a lithium battery, comprising a mounting frame 1, a lithium battery body 2 placed inside the mounting frame 1, mounting blocks 3 that cooperate with the mounting frame 1 being fixedly installed on the periphery of the upper part of the lithium battery body 2, an anti-theft plate 5 being fixedly installed on the bottom of the lithium battery body 2, an anti-theft component 6 being provided on the bottom wall of the mounting frame 1, fixing bolts 7 being provided on the upper side of each of the four corners of the mounting blocks 3, and threaded grooves 8 that are threadedly engaged with the fixing bolts 7 being provided on each of the four corners of the upper side of the mounting frame 1, the anti-theft component 6 comprising a fixing block 601 installed on the bottom wall of the mounting frame 1, and a cavity 602 being provided on the inner wall of the fixing block 601.
[0006] Furthermore, a fixing frame 603 is installed on each of the opposite sides inside the cavity 602. Two conductive clips 604 are slidably fitted on the inner walls of the two fixing frames 603. A first spring 605 is installed between the outer sides of the two conductive clips 604 and the inner walls of the fixing frames 603.
[0007] Furthermore, a conductive copper sheet 608 is disposed between the two sets of conductive clips 604, and a wire 4 is disposed between the two sets of conductive clips 604 and the lithium battery body 2. The side of the two sets of conductive clips 604 closest to the conductive copper sheet 608 is open. The two sets of conductive clips 604 are combined with the conductive copper sheet 608 and the wire 4 to form a closed circuit.
[0008] Furthermore, a sliding groove 606 is provided through the inner wall of the cavity 602, and a connecting block 607 is slidably fitted on the inner wall of the sliding groove 606. The conductive copper sheet 608 is fixedly installed at one end of the connecting block 607, and an anti-theft block 609 is installed at the end of the connecting block 607 located outside the fixing block 601.
[0009] Furthermore, a fixing rod 10 is installed on one side of the connecting block 607 inside the cavity 602, and a fixing plate 9 that slides with the fixing rod 10 is installed inside the cavity 602. A second spring 11 is installed between the connecting block 607 and the fixing plate 9.
[0010] Furthermore, an iron plate 12 is installed at the bottom end of the fixing rod 10, and an electromagnet 13 that cooperates with the iron plate 12 is fixedly installed inside the cavity 602. The electromagnet 13 is electrically connected to two sets of conductive clips 604.
[0011] Furthermore, the side wall of the slide 606 is provided with a groove 610, the inner wall of the groove 610 is slidably fitted with a locking block 611, a third spring 612 is installed between one side of the locking block 611 and the inner wall of the groove 610, and one side of the connecting block 607 is provided with a locking groove 613 that cooperates with the locking block 611.
[0012] Furthermore, the bottom of the anti-theft plate 5 is provided with an anti-theft groove 614 that cooperates with the anti-theft block 609, the side wall of the anti-theft groove 614 is provided with a slot 615, and one side of the anti-theft block 609 is provided with a pin 616 that cooperates with the slot 615.
[0013] The beneficial effects of this utility model are: 1. This utility model uses a circuit power-off triggering anti-theft mechanism. The cooperation between the pin and the slot can quickly and firmly fix the lithium battery body, effectively preventing theft and greatly improving the anti-theft security of the lithium battery. Utilizing common components such as electromagnets and springs, through reasonable structural layout and linkage design, it achieves the function of automatic locking after theft and cannot be easily reset. The structure is simple and reliable, and easy to manufacture and maintain.
[0014] 2. Because the conductive copper sheet has disconnected the two sets of conductive clips, even if a thief tries to reconnect the power, the electromagnet will not work, the connecting block will not reset, and the pin will always remain in the slot, continuously fixing the lithium battery body and preventing it from being stolen.

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Please refer to Figures 1 to 6This utility model provides a technical solution: an anti-theft structure for a lithium battery, including a mounting frame 1, a lithium battery body 2 placed inside the mounting frame 1, mounting blocks 3 that cooperate with the mounting frame 1 fixedly installed on the periphery of the upper part of the lithium battery body 2, an anti-theft plate 5 fixedly installed on the bottom of the lithium battery body 2, an anti-theft component 6 provided on the bottom wall of the mounting frame 1, fixing bolts 7 provided on the upper side of the four corners of the mounting blocks 3, and threaded grooves 8 that are threadedly engaged with the fixing bolts 7 at the four corners of the upper side of the mounting frame 1, the anti-theft component 6 including a fixing block 601 installed on the bottom wall of the mounting frame 1, and a cavity 602 opened in the inner wall of the fixing block 601.
[0019] In this embodiment, a fixing frame 603 is installed on both opposite sides of the cavity 602. Two conductive clips 604 are slidably fitted on the inner walls of the two fixing frames 603. A first spring 605 is installed between the outer side of the two conductive clips 604 and the inner wall of the fixing frame 603. A conductive copper sheet 608 is provided between the two sets of conductive clips 604. A wire 4 is provided between the two sets of conductive clips 604 and the lithium battery body 2. The side of the two sets of conductive clips 604 closest to the conductive copper sheet 608 is open. The two sets of conductive clips 604 are combined into a closed circuit by conductive copper sheets 608 and wires 4. A sliding groove 606 is provided through the inner wall of the cavity 602. A connecting block 607 is slidably fitted on the inner wall of the sliding groove 606. The conductive copper sheet 608 is fixedly installed at one end of the connecting block 607. An anti-theft block 609 is installed at the end of the connecting block 607 located outside the fixing block 601. A fixing rod 10 is installed on one side of the connecting block 607 located inside the cavity 602. A fixing plate 9 is installed inside the cavity 602 and slidably fitted with the fixing rod 10. A second spring 11 is installed between the connecting block 607 and the fixing plate 9. An iron sheet 12 is installed at the bottom end of the fixing rod 10. An electromagnet 13 that cooperates with the iron sheet 12 is fixedly installed inside the cavity 602. The electromagnet 13 is electrically connected to the two sets of conductive clips 604.
[0020] Specifically, when the lithium battery body 2 is stolen and its circuit is cut, the closed circuit formed by the two sets of conductive clips 604 through the conductive copper sheet 608 and the wire 4 will be de-energized, thereby de-energizing the electromagnet 13. The iron sheet 12 releases the attraction force generated by the electromagnet 13, and the connecting block 607 slides through the force of the second spring 11. The sliding connecting block 607 causes the conductive copper sheet 608 to release the electrical connection between the two sets of conductive clips 604. When the closed circuit is energized again, since the two sets of conductive clips 604 are in an open state, the electromagnet 13 cannot work, and the connecting block 607 cannot be reset.
[0021] In this embodiment, the side wall of the slide groove 606 is provided with a groove 610, and the inner wall of the groove 610 is slidably fitted with a locking block 611. A third spring 612 is installed between one side of the locking block 611 and the inner wall of the groove 610. One side of the connecting block 607 is provided with a locking groove 613 that cooperates with the locking block 611. The bottom of the anti-theft plate 5 is provided with an anti-theft groove 614 that cooperates with the anti-theft block 609. The side wall of the anti-theft groove 614 is provided with a slot 615. One side of the anti-theft block 609 is provided with a pin 616 that cooperates with the slot 615.
[0022] Specifically, when the lithium battery body 2 is stolen and its circuit is cut, the two sets of conductive clips 604 will be de-energized through the closed circuit formed by the conductive copper sheet 608 and the wire 4, thereby de-energizing the electromagnet 13. The iron sheet 12 releases the attraction force generated by the electromagnet 13, and the connecting block 607 will slide through the force of the second spring 11. The sliding connecting block 607 will cause the anti-theft block 609 to slide in the anti-theft groove 614, so that the pin 616 is inserted into the slot 615, which will fix the lithium battery body 2 and play an anti-theft role.
[0023] When the device is in use, under normal operating conditions, the lithium battery body 2 is installed in the mounting frame 1 via the mounting block 3 and fixing bolts 7. The electromagnet 13 in the anti-theft component 6 is energized, generating a magnetic force to attract the iron piece 12, keeping the connecting block 607 in a certain position. The conductive copper piece 608 is electrically connected to the two sets of conductive clips 604, and the closed circuit works normally. When the lithium battery body 2 is stolen and the circuit is cut, the closed circuit composed of the two sets of conductive clips 604 is de-energized, the electromagnet 13 loses power, and the iron piece 12 releases its magnetic force. Under the force of the second spring 11, the connecting block 607 slides along the slide groove 606, causing the conductive copper sheet 608 to disconnect from the conductive clip 604. At the same time, the anti-theft block 609 slides in the anti-theft groove 614, and the pin 616 is inserted into the slot 615, fixing the lithium battery body 2 in the mounting frame 1. Even if someone tries to turn on the power again, the electromagnet 13 cannot work because the conductive clip 604 is in the disconnected state, the connecting block 607 cannot be reset, and the pin 616 remains in the slot 615, thus effectively preventing the lithium battery from being stolen.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
