Embodiment 1

[0030] see Figure 1-5 As shown, a new energy battery module mounting frame with an elastic protection device according to the present invention includes a box body 1 and a box cover 2 that cooperate with each other; The partition plate 3 and the inner wall of the box body 1 form an installation cavity 4 for installing the battery module. A group of evenly distributed elastic bodies 5 are fixed on the inner wall of the installation cavity 4. The side walls of the battery module are connected with The bump 6 that is misplaced and interference-fitted with the elastic body 5; when working, when the mounting bracket in the prior art is in use, when the vehicle on which the battery module is installed bumps during travel, the battery module It is easy to be bumped and impacted, so that the battery module is easily deformed or damaged, which affects the service life of the battery module; when the mounting bracket in the present invention is in use, the battery module is inserted in...

Embodiment 2

[0040] see Figure 6 As shown, a ventilation pipe 32 is installed inside the communication groove 14, and the ventilation pipe 32 is made of rigid material. The outer end of the trachea 32 is not in contact with extrusion; when working, the air pipe 32 provided can support the communication groove 14, reducing the extrusion fit between the block 13 and the card cavity 12, causing the communication groove 14 to shrink and affect the gas flow. At the same time, by setting the position of the communication groove 14 and the air pipe 32, when the block 13 is pressed in from the mouth of the card cavity 12, the opening of the card cavity 12 is in contact with the rigid air pipe 32, causing the block 13 to be difficult to press in.

[0041]Working principle: Insert the battery module into each installation cavity 4 from the opening at the top of the box body 1, and make the protrusion 6 on the side wall of the battery module and the elastic body 5 engage in dislocation. At this time...

Abstract

The invention relates to the field of battery technology, specifically a new energy battery module mounting frame with an elastic protection device, including a box body and a box cover; a set of partitions are arranged on the inner wall of the box, and the partitions and The inner wall of the box forms an installation cavity, and a group of evenly distributed elastic bodies is fixedly connected to the inner wall of the installation cavity, and a bump is connected to the side wall of the battery module; the present invention can have a certain positioning effect on the battery module , and when the vehicle bumps during driving, the elastic body can play a certain buffering and shock-absorbing effect on the battery module shaking in the horizontal direction, and at the same time, the elastic body can buffer the shaking of the battery module in any direction in the horizontal direction, It greatly improves the safety and stability of the battery module during use. At the same time, there is a gap between the battery module and the side wall of the installation cavity, which provides a certain deformation space for the thermal expansion of the battery module and further improves the battery life. The safety of the mod while in use.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a new energy battery module mounting frame with an elastic protection device. Background technique [0002] With the development of new energy vehicles and the maturity of power batteries, power batteries are developing towards higher energy density, smaller volume and higher power density. Compared with aluminum-cased batteries and steel-cased prismatic batteries, pouch batteries packaged with aluminum-plastic film have the advantages of small size, light weight, high safety, and various designs of external dimensions. The power battery pack is an important part of the electric vehicle, and the battery module is the core component of the power battery pack. [0003] There are also some technical solutions for battery module mounting brackets in the prior art, such as a Chinese patent with a patent number of 2020209174635, which proposes a battery module mounting bracket, batte...
