[0002] Electric vehicles are becoming increasingly popular as a means of transportation. In order to achieve lightweight and long battery life, existing electric vehicles are mainly powered by high-efficiency lithium batteries. Lithium batteries are expensive, so theft of electric vehicle batteries occurs from time to time. At present, most electric vehicle batteries still use mechanical anti-theft, and the anti-theft function is achieved through padlocks. However, this method can only prevent ordinary secret thefts, and it is difficult to prevent theft by violent disassembly. In addition, the battery is small in size and light in weight, which is convenient for thieves to transport and transfer, so it is generally difficult to find it after it is lost. Therefore, it is necessary to design an anti-loss device for electric vehicle batteries, which can still trace the trajectory and location of the battery after the electric vehicle battery is mechanically damaged and stolen.

DETAILED DESCRIPTION

[0016] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0017] like Figure 1-4As shown, a battery anti-lost device for electric vehicles is mainly composed of a battery compartment body 1, a battery pack 2, a Bluetooth module and a pressing seat 4. The battery is tracked and positioned by arranging a controller 3 on the battery pack 2, wherein the battery compartment body 1 has a receiving cavity 13, in which the battery pack 2 is placed, and a rubber sleeve 6 is arranged in the receiving cavity 13 outside the battery pack 2; the controller 3 has a built-in Find My program, a Bluetooth module 31 is arranged inside, a sensor switch 32 is arranged at the top, and a control switch is also installed on the controller 3. Before placing the controller into the battery compartment body 1, the control switch is pressed to start the controller 3, and a through hole 61 matching the sensor switch 32 is opened on the rubber sleeve 6.

[0018] A pressing seat 4 is provided above the induction switch 32. The pressing seat 4 and the induction switch 32 are coordinated to control the Find My program and the Bluetooth module 31 in the controller 3. When the pressing seat 4 and the induction switch 32 are in normal contact, they are in a default state, and the Find My program 32 does not work. When the battery compartment 1 is disassembled and the pressing seat 4 is separated from the induction switch 32, the induction switch 32 triggers a signal to the controller 3, and the controller enters a working state, and the Find My program 32 does not work. My program starts to work, and connects with the surrounding Apple Bluetooth devices through the Bluetooth module 31 to achieve end-to-end positioning transmission, and sends the GPS position in the controller 3 module to the mobile phone initially bound to the battery, so that the user can promptly know the situation of battery theft and obtain the current location of the battery; the outer side of the clamping seat 4 is provided with a protective cover 5, and the top of the protective cover 5 is provided with a dust cover 51, and the dust cover 51 is fixed to the protective cover 5 by internal and external threads. The top of the battery compartment body 1 is provided with a mounting groove 12 that matches the protective cover 5, and the mounting groove 12 is connected to the accommodating cavity 13. At the same time, a through groove 41 is provided in the clamping seat 4, and a gear 42 is provided in the through groove 41. At the same time, a rack plate 43 is meshed and connected on one side of the gear 42, and the end of the rack plate 43 away from the gear 42 passes through the clamping seat 4, and the side wall of the mounting groove 12 is provided with a card slot 11 that matches the movable plate 33. As the gear 42 rotates, relative movement occurs between the rack plate 43 and the gear 42, causing the rack plate 43 to move left and right. Inserting the card slot 11 means locking, and withdrawing the card slot 11 means unlocking. An annular groove 421 is provided at the top of the gear 42, and a through groove 2 44 connected to the annular groove 421 is provided on the pressing seat 4. The through groove 2 44 is cooperated with an unlocking sleeve 45. A groove is provided at the bottom end of the unlocking sleeve 45 so that the outer edge of the bottom of the unlocking sleeve 45 can be inserted into the annular groove 421 on the gear 42, and the length of the unlocking sleeve 45 is greater than the sum of the depths of the through groove 2 44 and the annular groove 421. When in use, the unlocking sleeve 45 needs to be inserted into the pressing seat 4 along the through groove 2 44 and abut against the annular groove 421 of the gear 42. The gear 42 is driven to rotate by rotating the unlocking sleeve 45. The end of the rack plate 43 away from the gear 42 is inclined upward, and the pressing seat 4 is provided with a yielding groove 46 matching it.

[0019] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
