Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid batteries, in particular to a vehicle lead-acid battery which is easy to install. Background Art

[0002] Lead-acid batteries are a type of rechargeable battery. The advantage of lead-acid batteries is that the electromotive force is relatively stable during discharge, while the disadvantage is that the specific energy (electrical energy stored per unit weight) is small and they are highly corrosive to the environment. The batteries have a stable operating voltage, a wide operating temperature and current range, can be charged and discharged for hundreds of cycles, have good storage performance (especially suitable for dry-type charged storage), and are relatively low in cost. Therefore, they are widely used in electric vehicles. When lead-acid batteries are used, multiple lead-acid batteries need to be connected in series. When connecting lead-acid batteries in series, users need to waste time fixing the connecting cables to the electrode columns of the lead-acid batteries, which increases the difficulty of connecting lead-acid batteries in series and reduces the efficiency of lead-acid batteries in series.

[0003] After searching, the high-efficiency lead-acid battery for electric vehicles with announcement number CN218334212U includes: a plurality of independently operable battery components, the battery components are used for power supply; a negative pole and a positive pole, the negative pole and the positive pole are both installed on the battery components, and the negative pole is located on one side of the positive pole; a convex tooth, the convex tooth is provided on the outside of the negative pole and the positive pole; a connecting ring, the connecting ring is sleeved on the negative pole and the positive pole. The utility model allows the first connecting cable and the second connecting cable to be connected to the first battery body, the second battery body, the third battery body and the fourth battery body by engaging the convex teeth on the negative pole and the positive pole with the tooth grooves on the connecting ring, so that the user does not need to waste time fixing the first connecting cable and the second connecting cable to the positive pole and the negative pole, thereby reducing the difficulty of connecting the lead-acid batteries in series and improving the efficiency of the lead-acid batteries in series.

However, the engagement and installation of the convex teeth and the tooth grooves on the connecting ring will cause the engagement to loosen due to repeated disassembly and installation, and the vehicle will also loosen due to bumps during driving.
