Embodiment 1

[0042] Embodiment one: if Figure 1-3 As shown, the battery of this embodiment includes a housing 1, an upper cover 3, a pole 6, a lithium battery and a conductive strip, the housing 1 is in the shape of a cuboid, and the opening of the housing is sealed by an upper cover 3; the upper cover 3 is embedded with a pole 6. The outer end of the pole 6 is connected to the conductive strip. The casing 1 has a built-in lithium battery, and the outer walls around the casing 1 form reinforcing ribs 4, the cross section of which is rectangular, that is, the reinforcing ribs 4 are horizontal bars. The reinforcing ribs 4 are parallel to the edge of the upper opening 2 of the housing, and are evenly arranged on the outer walls of the housing 1 in the transverse direction. The reinforcing ribs on the adjacent outer walls of the housing are connected, that is, the four reinforcing ribs on the same horizontal plane of the outer walls of the housing are connected in a circle. The horizontal r...

Embodiment 2

[0043] Embodiment two: if Figure 4-6 As shown, a liquid filling column 31 is formed upwards in the middle of the upper cover 3 , and a through hole 311 is formed inside the liquid adding column 31 , and the through hole 311 communicates with the inside of the battery case. Four arc-shaped annular grooves 32 are formed on the upper cover of the periphery of the liquid-filling column 31. The wall thickness of the arc-shaped annular grooves 32 is determined by the gas pressure that the battery can withstand. The four arc-shaped annular grooves 32 form a The circle surrounds the filling column 31. During the use of the battery, after a certain amount of gas is generated inside and reaches the specified pressure, the arc-shaped ring groove 32 will be broken by the internal air pressure, and the part surrounded by four arc-shaped ring grooves 32 will act as a safety valve for the battery. Function, through this part, the gas generated inside the casing is discharged in time, avoid...

Embodiment 3

[0048] Embodiment three: as Figure 7-11 As shown, when the upper cover 3 is molded, the battery pole 6 is molded into it at the same time, so that the upper cover 3 and the battery pole 6 are connected into one body without additional assembly. In this way, the tightness between the pole and the upper cover is enhanced, and there is no need to use additional O-rings to strengthen the tightness between the pole and the cover. In addition, it enhances the overall manufacturability of the battery, reduces procedures, saves costs, and enhances the conductivity of the entire battery pole surface.

[0049] The upper cylinder 331 of the battery pole 6 extends out of the upper cover 3 , and the lower part of the battery pole 6 is provided with two holes 332 . A screw hole is formed in the middle part of the upper section of the battery pole 6, and the rivet 7 extends into the screw hole after passing through the conductive strip 5, and the conductive strip 5 is fixedly connected wit...

Abstract

The invention belongs to the technical field of battery manufacturing of electric motor cars and in particular relates to an improved battery; the battery comprises a shell, an upper cover, a pole rod, a lithium battery and an electric conducting bar; the shell is a cuboid shape, and the opening of the shell is sealed by the upper cover, and a strengthening rib is formed by the outer wall of the shell forms, and the lithium battery is arranged in the shell; the pole rod is embedded on the upper cover, and the outer end of the pole rod is connected with the electric conducting bar; the strengthening rib is transversely and uniformly distributed by the way that the strengthening rib is parallel to the edge of the opening of the shell. The improved battery has the advantages of high-strength shell, good heat radiating performance, simple structure, high using safety, high sealing property, long service life and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of electric vehicle battery manufacturing. 【Background technique】 [0002] As we all know, electric vehicles are a labor-saving and fast means of transportation, and are very popular among users. And because electric vehicles are a kind of green and environment-friendly means of transport, with the general enhancement of social environmental protection awareness, electric vehicles are becoming more and more popular, and the electric vehicle industry is also strongly supported by government departments. The battery as the power source of electric vehicles must also meet the market demand for electric vehicles. The battery is the "heart" of the electric vehicle. The performance of the battery directly affects the quality of the electric vehicle, so the performance of the battery is extremely important. [0003] The existing battery structure has the following defects: [0004] 1. The shell of the battery i...
