Embodiment approach 1

[0058] The lead storage battery of this embodiment is figure 1 As shown, there are an electric tank 5, a middle cover 6, a plate assembly 4 and an end pole 7. The end pole is a U-shaped pole, and one end 8 of the U-shaped pole penetrates the middle cover 6. The U-shaped pole The other end 9 of the column is side-welded with the bus bar 3 and the tab 2 of the electrode plate assembly 4 to form a welded body. The inner surface of the middle cover corresponding to the welded body has a concave housing surrounded by a baffle. Part 6a, the welding body is embedded in the concave receiving part 6a and the welding body and the concave receiving part are adhesively fixed together by the adhesive 10 provided in the concave receiving part. One end of the U-shaped pole is embedded in the hollow part of the U-shaped pole.

[0059] In the lead storage battery of the present embodiment, in order that one end of the U-shaped pole penetrates the middle cover, the length (L1) of the one end 8 of ...

Embodiment approach 2

[0070] The lead storage battery 1 of the second embodiment is based on the lead storage battery 1 of the first embodiment, such as figure 2 As shown, an L terminal 13 is connected to the end of one end 8 of the U-shaped pole.

[0071] According to the final technical effect to be achieved, other constituent elements can be appropriately selected from the foregoing detailed description.

Embodiment approach 3

[0073] The lead storage battery 1 of the third embodiment is based on the lead storage battery 1 of the first embodiment, such as image 3 As shown, a copper core 14 is inserted into the above-mentioned U-shaped pole to ensure that it can be used normally even in the case of large current discharge.

[0074] According to the final technical effect to be achieved, other constituent elements can be appropriately selected from the foregoing detailed description.

Abstract

The invention provides a lead storage battery, which is characterized by comprising an electrolytic bath, a middle cover, a polar plate group and a terminal polar post, wherein the terminal polar post is a U-shaped polar post, one end of the U-shaped polar post penetrates through the middle cover, the other end of the U-shaped polar post as well as a busbar and polar lugs of the polar plate group are subjected to side-face welding to form a welding body, the inner surface of the middle cover, corresponding to the welding body, is provided with a concave accommodating part formed by enclosure of baffles, the welding body is embedded in the concave accommodating part, the welding body and the concave accommodating part are bonded and fixed together by using bonding agents placed in the concave accommodating part, and one end of the concave accommodating part is embedded into a hollow part in the U-shaped polar post. According to the invention, by means of specially designing a connection and fixation structure among the terminal polar post, the polar plate group and the middle cover, the terminal polar post is made good in stability and vibration resistance, and the entire battery is good in vibration resistance, small in internal resistance and good in high-rate discharge property.

Description

Technical field [0001] The present invention relates to a lead storage battery, in particular to a lead storage battery with good stability and vibration resistance of the terminal poles, good vibration resistance of the entire battery, low internal resistance, and excellent high-rate discharge characteristics. Background technique [0002] Lead-acid batteries are not only used as the power source and backup power source for starting vehicles, but are also widely used as the main power source, that is, as a power source for independent charging and discharging equipment such as electric cars, electric bicycles, electric motorcycles, electric scooters, small electric mopeds, golf Power supply for golf carts, solar batteries, etc. In these applications, the lead-acid battery has a large current when starting, and during use, the vehicle runs on roads and suburbs with a lot of turbulence, and the two electrode terminals are subjected to large and frequent vibrations, so the electrod...
