DETAILED DESCRIPTION

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Reference Figures 1 to 4 , is an embodiment of the present invention, which provides a sliding battery pack collision test fire extinguishing fixture. The fixture consists of three major parts: a battery pack locking base 100, a fire extinguishing box 200, and a water storage tank 300. A water injection pipe 400 and a smoke exhaust pipe 500 are connected between the fire extinguishing box 200 and the water storage tank 300. In this embodiment, the water injection pipe 400 and the smoke exhaust pipe 500 are both hoses that can be freely dragged within a predetermined space. Among them, the battery pack locking base 100 is set on the detection slide, and the battery pack to be tested is fixed on the battery pack locking base 100. When the battery pack needs to be subjected to collision detection, the detection slide accelerates to drive the battery pack locking base 100 to accelerate linearly, thereby completing the collision test of the battery pack.

[0025] At the same time, the fire extinguisher box 200 is suspended directly above the battery pack locking base 100 and moves synchronously with the battery pack locking base 100. In this embodiment, three water injection holes 201 and one smoke exhaust hole 202 are provided on the upper part of the fire extinguisher box 200. The three water injection holes 201 are connected to the water injection pipe 400, thereby connecting to the water storage tank 300, and the water storage tank 300 is pre-stored with water for fire extinguishing. The top of the water storage tank 300 is provided with a first smoke exhaust outlet 301 and a second smoke exhaust outlet 302; the first smoke exhaust outlet 301 is directly connected to the outside atmosphere, and the second smoke exhaust outlet 302 is connected to the smoke exhaust hole 202 of the fire extinguisher box 200 through the smoke exhaust pipe 500.

[0026] The outer contour of the fire extinguisher 200, where it connects to the battery pack locking base 100, is equipped with a sealing gasket. When a battery pack is impacted and catches fire, the fire extinguisher 200 drops vertically and connects to the battery pack locking base 100. The fire extinguisher 200 and the battery pack locking base 100 are connected and pressed together. The sealing gasket is compressed to form a predetermined elastic deformation, forming a seal that covers the burning battery pack. As the battery pack burns within the fire extinguisher 200, the water tank 300 rapidly drains water, which flows into the fire extinguisher 200 via the water inlet pipe 400. Smoke within the fire extinguisher 200 is discharged into the water tank 300 via the exhaust pipe 500. The smoke within the water tank 300 is filtered by water and then discharged through the first exhaust outlet 301. Because the fire extinguisher 200 forms a relatively enclosed space, oxygen is isolated, and the continuous influx of water eventually extinguishes the battery pack fire, ultimately achieving fire detection of battery pack impact fires.

[0027] It should be noted that the battery pack locking base 100 can be installed in the X or Y direction on the detection slide. Different installation methods are suitable for battery packs of different sizes. Depending on the battery pack model, the battery pack is locked and fixed through different matrix holes 101. Threaded holes are provided on the frame of the battery pack locking base 100. The battery pack locking base 100 is pushed into the predetermined position at the front end of the detection slide from the rear end and locked with bolts at the threaded holes at the rear end of the battery pack locking base 100. Several matrix holes 101 are provided on the battery pack locking base 100 for matching and locking battery packs of different sizes.

[0028] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
