Embodiment Construction

[0045] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0046] In order to solve the shortcomings and problems of the existing battery pack airtight test device, the present invention provides a device that is easy to realize the automatic airtight test of battery packs for new energy vehicles based on the original process requirements and combined with the design concept of automatic airtight test . The airtight testing device in this embodiment mainly includes three parts: a blocking mechanism, a power mechanism and a control system.

[0047] The blocking mechanism is a basic structure, and its technical principle is: through the relative movement of two rigid components, the elastic component between them is squeezed, and the elastic component expands under pressure. Such as figure...

Abstract

The invention provides a battery pack automation airtightness testing device. The battery pack automation airtightness testing device at least comprises a plug, a plug seat and an elastic component, the plug is used for being connected to a connector of a battery pack, the elastic component is mounted between the plug and the plug seat, and the elastic component is arranged to be: the elastic component is extruded to expand to block the connector as the plug and the plug seat are closer. The elastic component preferably adopts a rubber sealing ring. The battery pack automation airtightness testing device has the beneficial effects that the device can automatically detect whether the airtight plug is mounted in place or not; the device can rapidly seal the connector, shorten the testing time of a single piece and improve the beat; and the device can automatically detect whether the plug gets loose or not in the testing process.

Description

technical field [0001] The invention relates to an airtight test device, in particular to an automatic airtight test device for a battery pack, which is used for the airtight test of a power battery pack for a new energy vehicle and belongs to the technical field of power batteries for a new energy vehicle. Background technique [0002] At present, the air tightness test of power battery packs for new energy vehicles generally uses one-to-one independent plugs for sealing. Open and cause the possibility of mistesting, unable to realize automated testing. [0003] In order to solve these problems, those skilled in the art are devoting themselves to developing a battery pack airtight testing device that is easy to realize automatic testing. Contents of the invention [0004] The technical problem to be solved by the present invention is: the motorized airtight test of the battery pack requires a device that is easy to realize automatic testing, and realizes the detection of...
