Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, and in particular to a battery protection device for electric vehicles. Background Technology

[0002] As electric vehicles become the mainstream tool for short-distance urban travel and daily commuting, batteries, as their core power component, have gradually become a frequent target of theft due to their characteristics of "high value, easy disassembly, and high liquidity." This has directly driven the research and development and application of anti-theft battery protection devices. With the number of electric vehicles exceeding 300 million (as of 2024), battery theft has become a prominent issue affecting public safety. Users have an increasingly urgent need for anti-theft devices that are "anti-disassembly, easy to identify, and traceable." At the same time, industry regulators have also placed higher demands on the safety features of electric vehicles. Traditional battery installation methods without specific anti-theft designs can no longer meet the dual needs of user property security and social security management. Against this backdrop, electric vehicle battery protection devices focusing on anti-theft functions have emerged.

[0003] However, considering the risk of theft and the current state of the industry, early electric vehicle batteries were mostly fixed with simple screws or clips, making disassembly extremely easy. Using tools such as screwdrivers and wrenches, it only took 1-2 minutes to remove the battery from the vehicle and steal it.

[0004] Therefore, we provide an electric vehicle battery protection device to solve the above problems. Utility Model Content

A rubber sleeve washer is sleeved at the bottom of the through-type hexagonal bolt, and a bottom auxiliary fixing nut is threadedly fixed at the bottom end of the through-type hexagonal bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are: With the embedded two-end positioning brackets, during use, the two embedded two-end positioning brackets are inserted into the top of the inner wall of the electric vehicle battery chamber. The front end positioning and fixing blocks are threadedly connected to the pre-drilled holes in the battery chamber. The rear end frame fixing assembly is welded and fixed at the rear end of the positioning bracket. The multiple bolt holes on its surface can accommodate multiple battery chamber models for threaded connection and fixation. This allows the embedded two-end positioning brackets to be fitted and fixed to the top of the battery chamber. Multiple batteries are connected in series and fixed inside the embedded two-end positioning brackets, and then threadedly connected and fixed through the top battery top protective beam. After fixing, the through hexagonal bolts at both ends are further shielded by the cover at both ends of the top of the battery chamber, thus protecting the entire series of batteries and increasing the anti-theft effect.
