Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery testing technology, and in particular to a safety device for testing batteries of new energy vehicles. Background Technology

[0002] Safety devices for testing new energy vehicle batteries are designed to minimize the occurrence of major accidents such as battery explosions and fires during the testing of new batteries, ensuring the safety of personnel and the integrity of equipment. They also play a crucial role in protecting the safety of testing personnel and equipment.

[0003] Currently, in the extrusion and puncture tests of new energy vehicle batteries, the safety and reliability of the battery or cell are mainly tested by simulating the deformation caused by external extrusion or the puncture by a sharp object. Through the extrusion / puncture test, the situation of the battery after being deformed or punctured by external impact is simulated, and test data is obtained to provide experimental data and basis for optimizing product design, as well as for safety risk assessment and verification. The battery is considered qualified if it does not explode or catch fire. However, in practical applications, the inventors have found that the explosion or fire caused by the battery being extruded / punctured can cause injury to the test personnel. Therefore, we propose a safety device for testing batteries in new energy vehicles. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A safety device for testing batteries of new energy vehicles includes a test housing, an inner cavity of which is provided with a sealing column, the sealing column is driven by a first driving device, a sealing ring is installed on the sealing column, and a test probe for squeezing or puncturing is installed at the bottom of the sealing column.

[0008] The bottom wall of the inner cavity of the test chamber is equipped with a platform for placing new energy vehicle batteries. A steel plate cover is inserted and installed on the platform. The steel plate cover is driven by a second driving device. A sealing sleeve is installed on the steel plate cover. During the test, the sealing column is sealed and installed inside the steel plate cover by the sealing ring. The steel plate cover is sealed and installed inside the platform by the sealing sleeve.

[0009] As an improved technical solution, the first driving device includes a multi-stage hydraulic push rod, one end of which is mounted on the inner cavity top wall of the test housing, and the piston end of which is mounted on the top of the sealing column.

[0010] As an improved technical solution, the outer surface of the sealing column is provided with a plurality of sealing grooves corresponding to the sealing ring, and the plurality of sealing grooves are equidistantly arranged along the axial length direction of the sealing column, and the sealing grooves are adapted to the sealing ring.

[0011] As an improved technical solution, the top of the platform is provided with an upper snap-fit ​​groove corresponding to the steel plate cover, and during the test, the steel plate cover is sealed and installed in the upper snap-fit ​​groove by the sealing sleeve;

[0012] The inner wall of the upper snap-fit ​​groove is provided with a lower snap-fit ​​groove, and the bottom of the steel plate cover has an integrally formed snap-fit ​​frame corresponding to the lower snap-fit ​​groove, and the snap-fit ​​frame is adapted to the lower snap-fit ​​groove.

[0013] As an improved technical solution, the top of the steel plate cover is provided with a cylindrical groove corresponding to the sealing column, and the cylindrical groove is adapted to the sealing column. During the test, the sealing column is sealed and installed inside the steel plate cover through the sealing ring and the cylindrical groove.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model involves placing the new energy vehicle battery to be tested on a platform and closing the cabinet door. Then, an electric push rod is activated, moving a steel plate cover closer to the platform until it covers the battery and the locking frame engages with the lower locking groove. Simultaneously, the steel plate cover is sealed in the upper locking groove by a sealing sleeve. Next, a multi-stage hydraulic push rod is activated, moving a sealing column that in turn moves the test probe closer to the battery until it enters a cylindrical groove. The sealing ring then seals the groove. Simultaneously, the test probe performs a compression or puncture test on the battery. During this process, the steel plate cover provides protection and effectively reduces the risk of battery testing, facilitating battery testing and minimizing injuries to personnel from battery compression / puncture explosions or fires.

[0018] 2. This utility model, by setting up a steel plate cover, a sealing ring, and a sealing sleeve, provides a seal during testing. The sealing ring and sealing sleeve effectively isolate external air, reducing the risk of injury to test personnel from fire caused by the new energy vehicle battery. The steel plate cover provides protection, effectively reducing the risk of new energy vehicle battery testing and the risk of injury to test personnel from explosion. This effectively reduces the risk of new energy vehicle battery testing and promotes the steady progress of new energy vehicle battery research and development. Attached Figure Description
