It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0016] In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. However, it is apparent that one or more embodiments can be practiced without these specific details. In addition, in the following description, the description of well-known structures and techniques is omitted to avoid unnecessary confusion of the concept of the utility model.

[0017] Please refer to Figs. 1-3This utility model relates to an explosion-proof lead-acid battery for vehicles, comprising an electrolyte tank 1, with a battery cover 2 fixedly mounted on the top of the electrolyte tank 1 by heat sealing. A nameplate is affixed to the upper surface of the battery cover 2. Multiple horizontally arranged tanks 3 are arranged inside the electrolyte tank, with adjacent tanks 3 separated by baffles 4. Each tank 3 has a filling hole on its upper surface corresponding to a position on the filling hole, and a vent plug 5 with a built-in safety valve is provided on the filling hole, meeting the requirements for valve-controlled maintenance-free operation. Each tank 3 contains an electrode group 6, which includes a positive electrode group and a negative electrode group. The positive electrode group includes several sets of parallel positive plates 7, with the tops of the sets of positive plates 7 connected together by a positive busbar 8. The negative electrode group includes several sets of parallel negative plates 9, with the sets of negative plates 9 connected together by a negative busbar 10. An insulating sleeve 11 is provided over the negative plates in each electrode group. Two positive terminal blocks 12 are provided at the top of the outermost positive busbar 8, and two negative terminal blocks 13 are provided at the top of the opposite negative busbar 10. In this embodiment, both the positive and negative terminals of the battery are lead terminals, and the batteries can be connected in series by welding. Each side of the battery has two positive terminal blocks 12 and two negative terminal blocks 13, and each terminal block can independently withstand the circuit current. In this embodiment, a protective plate 14 is also provided above the positive busbar 8 and the negative busbar 10. The thickness of the protective plate 14 is 0.3-0.5mm. In specific implementation, the protective plate 14 has several small heat dissipation holes for internal heat dissipation or liquid permeation. The protective plate 14 can effectively prevent conductive foreign objects from falling into the battery and avoid short circuits inside the battery. The parts of the positive terminal blocks 12 and the negative terminal blocks 13 that extend out of the battery cover are fitted with lead sleeves 15.

[0018] In summary, the vehicle explosion-proof lead-acid battery designed in this utility model uses a bipolar connection for the positive busbar 8 and negative busbar 9, avoiding safety hazards caused by improper single-pole design and improving overall safety performance. Simultaneously, the bipolar design allows for better current shunting and heat dissipation, resulting in a larger discharge current and reducing the risk of battery explosion. The bipolar structure also makes the internal current of the battery more stable, reducing safety issues caused by current fluctuations and thus enhancing battery stability. Furthermore, the vehicle explosion-proof lead-acid battery designed in this utility model, by using an insulating sleeve-type separator to separate the positive and negative plates, effectively avoids the defects of sheet-type separators that tend to shift and sink, preventing short circuits caused by the positive and negative plates at the bottom of the battery connecting together.
