Problems solved by technology

[0004] The invention overcomes the disadvantages of the existing batteries that shaking of the battery pack during installation and use may easily cause the battery pole group to be squeezed and damaged, thereby damaging the battery pack and causing the battery pack to fail, and provides an anti-shock and anti-collision structure for the battery of an electric vehicle. When the battery is installed and used, the shaking between the battery packs is not easy to cause the battery pole group to be squeezed and damaged, effectively preventing the battery pack from being damaged by collision, and greatly reducing the failure rate of the battery pack

Embodiment 1

[0024] Embodiment 1: An anti-shock and anti-collision structure of an electric vehicle battery (see attached figure 1 , attached figure 2 ), including a battery case 1 with a rectangular parallelepiped structure. A separator 2 is arranged inside the battery case to divide the battery case into several battery unit installation slots 3. Three partitions divide the battery case into six battery unit installation slots. One longer partition is arranged horizontally, two shorter partitions are arranged vertically, and three partitions are arranged crosswise to form two "ten"-shaped structures, and the partitions are integrally formed with the battery case. A battery electrode group unit 4 is installed in each battery unit installation groove. The inner bottom surface of the battery housing is provided with a shockproof support pad. The outer bottom surface of the battery case is provided with transverse ribs 5 and longitudinal ribs 6 , and the outer bottom surface of the batter...

Embodiment 2

[0026] Embodiment 2: An anti-shock and anti-collision structure of an electric vehicle battery (see attached Figure 3-6), its structure is similar to that of Embodiment 1, the main difference is that in this embodiment, there are several vertically arranged collision energy-absorbing grooves 10 on the outer walls around the battery case, and the collision energy-absorbing grooves have a "concave"-shaped structure And it protrudes from the outer wall of the battery case, and the crash pad covers the crash energy-absorbing groove inside. Three collision energy-absorbing grooves are arranged on both sides of the battery case in the length direction, and two collision energy-absorbing grooves are arranged on both sides of the battery casing in the width direction. , longitudinal ribs, and reinforced support feet are integrally formed with the battery case. The impact energy-absorbing groove of the "concave" structure has a strong ability to absorb impact force, which further pro...

Abstract

The invention discloses a storage-battery anti-shock crashproof structure, aims at solving the disadvantages that when a conventional storage battery is installed and used, a battery group is easily extruded and injured because of shaking of a battery pack, and thus the battery pack is injured and has faults. The structure comprises a storage batter housing, the storage battery housing is inside provided with separation plates dividing the storage battery housing into multiple cell unit installation grooves; each cell unit installation groove is inside provided with a battery group unit; the bottom surface outside the storage battery housing is provided with transverse ribs and longitudinal ribs, and is coated with a vibration-damping pad which covers the transverse ribs and the longitudinal ribs; and the outer lateral walls at periphery of the storage battery housing are all provided with vertically-arranged sidewall ribs, and are all coated with crashproof pads which cover the sidewall ribs.

Description

technical field [0001] The invention relates to a storage battery, more specifically, to an anti-shock and anti-collision structure of the storage battery of an electric vehicle, which is not easily damaged by collision. Background technique [0002] The battery pack of the electric moped is in use due to improper installation or loosening, coupled with bumpy road conditions, it is easy to cause collision friction. Through the anatomical analysis of the batteries returned to the market, the failure points are mainly distributed on the side of the positive terminal bus bar at the four corners of the battery and the positive bus bar side of the diagonal line, and are concentrated at the short position of the positive bus bar, indicating that the bus bar is relatively short. The collision extrusion bearing ability is poor. The main reason for the damage of the separator, leakage of active material, precipitation of active material, and degreasing of the returned battery pack i...
