Description

Technical Field

[0001] This utility model relates to the field of lithium batteries, and in particular to a lithium battery for golf carts that is easy to maintain. Background Technology

[0002] Golf carts and similar low-speed vehicles typically use lead-acid batteries for power. However, with the development of new energy technologies, newer models are gradually switching to lithium-ion batteries and other renewable energy sources. Older models, still within their service life, are seeing a shift towards lithium-ion batteries in the secondary market, where they replace lead-acid batteries with lithium-ion batteries. Lithium-ion batteries offer advantages such as light weight, high energy density, powerful performance, and long cycle life. This market context has led to the development of lithium-ion batteries for golf carts.

[0003] However, traditional lithium batteries, such as the patent application number CN202010838139.9 entitled "A Lithium Battery Pack for Automobiles", are complex in structure, difficult to disassemble, and complicated in replacing and repairing internal components. Utility Model Content

[0022] Please refer to the following: Figures 1 to 4 This utility model provides a lithium battery 10 for golf carts that is easy to maintain. The lithium battery 10 for golf carts that is easy to maintain includes: a lithium battery case 100, a lithium battery pack 200, a sealing mechanism 300, and a BMS battery system 400.

[0023] A lithium battery pack 200 is disposed inside a lithium battery casing 100, one end of which is open. A sealing mechanism 300 is detachably connected to the open end of the lithium battery casing 100. A battery management system (BMS) 400 is disposed on the sealing mechanism 300. The BMS 400 is electrically connected to the lithium battery pack 200.

[0024] The lithium battery casing 100 has a plurality of first threaded holes 101 evenly provided at its open end.

[0025] The sealing mechanism 300 includes a sealing plate 310, a sealing washer 320, two connecting components 330, several through-posts 340, and several first fixing bolts 350. In this embodiment, the sealing plate 310 is a rectangular plate structure.

In this embodiment, the sealing washer 320 is a soft rubber ring. In another embodiment, the sealing washer 320 is a soft silicone ring. The two connecting components 330 are symmetrically arranged on the sealing plate 310. The connecting components 330 include a connecting seat 331, several second fixing bolts 332, a fixing connecting plate 333, and a Z-shaped connector 334. The connecting seat 331 is connected to the sealing plate 310 by several second fixing bolts 332. Several connecting screw holes 302 are provided on the connecting seat 331. The fixed connecting plate 333 passes through the sealing plate 310 and is connected to the connecting seat 331. The fixed connecting plate 333 is connected to one end of the Z-type connector 334 by the second fixing bolt 332. The end of the Z-type connector 334 away from the fixed connecting plate 333 is connected to the receiving connecting plate 410 on the BMS battery system 400 by several second fixing bolts 332.

[0026] The receiving plate 410 of the BMS battery system 400 has a plurality of fixing holes 401 evenly distributed. Through-posts 340 are evenly distributed around the side of the sealing plate 310 facing the sealing gasket 320. Each through-post 340 is adapted to fit into a fixing hole 401, and is inserted into a corresponding fixing hole 401 and connected to the receiving plate 410. In this embodiment, the through-post 340 is a cylindrical structure. In another embodiment, the through-post 340 is a quadrangular prism structure. Furthermore, each through-post 340 is integrally formed with the sealing plate 310.

[0027] The first threaded hole 101 and the second threaded hole 301 are both adapted to the first fixing bolt 350.

Furthermore, the anti-slip sleeve 111 is made of soft rubber, which has elasticity, good toughness, and excellent anti-slip properties. Thus, the grip handle 110 on the top of the lithium battery casing 100 facilitates the handling of the easily repairable lithium battery 10 for golf carts.

[0029] During assembly, the aforementioned easily maintainable lithium battery 10 for golf carts is assembled by fixing two connecting seats 331 to the sealing plate 310 using second fixing bolts 332. A sealing gasket 320 is then bonded to the sealing plate 310. A fixing plate 333 is connected to one end of a Z-shaped connector 334 using second fixing bolts 332. The end of the Z-shaped connector 334 away from the fixing plate 333 is connected to a receiving plate 410 on the BMS battery system 400 using several second fixing bolts 332. The sealing plate 310 is then connected to the open end of the lithium battery casing 100 using first fixing bolts 350. In summary, the BMS battery system 400 is mounted on the sealing plate 310, which facilitates detachable connection to the lithium battery casing 100. This means that the BMS battery system 400 can be easily removed from the lithium battery casing 100, thus facilitating replacement or maintenance of the BMS battery system 400 and the lithium battery pack 200. The aforementioned easy-to-maintain lithium battery 10 for golf carts is easy to disassemble and maintain.
