The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] First embodiment

[0036] See also Figures 1 to 3 , shown is a battery module detection device in one embodiment of the utility model, including a test assembly 100 and a lifting assembly 200 connected to the test assembly 100;

[0037] The lifting assembly 200 includes a support base 210 and a driving connecting rod connected to the support base 210, wherein the driving connecting rod has a fixed end and a driving end, wherein the fixed end is connected to the test assembly 100, and the driving end is used to deform the driving connecting rod so that the driving connecting rod drives the test assembly 100 to move up and down during the deformation process;

[0038] The test assembly 100 includes at least one test probe 110, which is used to face the test point of the battery module. The test probe 110 can at least follow the test assembly 100 to make lifting movements, and the test point at least includes the positive and negative poles of the battery module.

[0039] In this embodiment, the driving connecting rod includes a driving force arm 220 and a fixed force arm 230, that is, the driving end can be the driving force arm 220, and the fixed end can be the fixed force arm 230. It should be noted that the driving force arm 220 and the fixed force arm 230 do not limit the number of force arms in the driving connecting rod, and it can also be other numbers, which is not specially explained here.

[0040] The driving force arm 220 and the fixed force arm 230 are rotatably connected at their ends close to each other, and are respectively connected to the test assembly 100 and the support base 210 at their ends away from each other;

[0041] Among them, at least two outer parts of the driving force arm 220 exceed the supporting range of the support seat 210, and at least a middle part is rotatably connected to the support seat 210.

[0047] It should be noted that in this embodiment, the wire 140 is specifically connected to the test terminal.
