Problems solved by technology

[0003]Current devices for impact testing battery packs can only perform impact tests on the front or side of the battery pack, and cannot test the impact performance of the bottom of the battery pack and evaluation, and the current device for impact testing battery packs can only perform impact tests on a single battery pack, but cannot perform impact test tests on battery packs that have been installed on the entire vehicle, while performing impact tests on individual battery packs The test cannot simulate the impact test effect of the battery pack installed on the vehicle

Embodiment Construction

[0023] The following is further described in detail through specific implementation methods:

[0024] The reference signs in the accompanying drawings of the description include: automobile 1, impact head 2, collision machine 3, lift 4, ground 5, limit block 6, track 7, acceleration sensor 8, buffer 9, moving block 10, Housing 11 , anti-backlash block 12 , second gear 13 , first gear 14 , torsion spring 15 , and rotating shaft 16 .

[0025] The embodiment is basically as attached Figure 1-Figure 4 Shown: a test device for simulating the bottom collision of a vehicle battery system, including a lift 4 and a collision machine 3 . The lift 4 is installed on the ground 5 and can lift the car 1 upwards. Roller wheels are installed on the bottom of the collider 3, so that the collider 3 can move on the ground 5. The collision machine 3 includes a housing 11, an impact head 2 and a launch cylinder that drives the impact head 2 to impact, and an air source is connected to the laun...

Abstract

The invention relates to the field of battery testing, in particular to a testing device for simulating bottom collision of a vehicle battery system, which comprises a lifting machine and a collision machine, the collision machine comprises a shell, an impact head and a launching cylinder for driving the impact head to impact, and the launching cylinder is connected with an air source. According to the scheme, the collision working condition of the battery at the bottom of the automobile in the Z direction can be simulated.

Description

technical field [0001] The invention relates to the field of battery testing, in particular to a testing device for simulating the bottom collision of a vehicle battery system. Background technique [0002] In the industrial development plans of countries around the world, new energy vehicles occupy a very important position. How to solve the safety problems brought by electric vehicles has always been a new topic and difficulty in the automotive industry. In the actual use of electric vehicles, the bottom protection of the battery is also very important. When the wheels pass over pits, bumps or stone roads, the bottom of the pure electric vehicle is extremely vulnerable to impact and scratches, while the bottom of the battery is usually located at the bottom of the car, and the bottom of the battery is also very vulnerable to impact and scratches. The impact and scratches at the bottom of the battery have a certain degree of concealment, and even in some accidents, althou...
