Description

Technical Field

[0001] This utility model belongs to the field of power battery testing technology, and specifically relates to a fire extinguishing and protection device for power battery simulated collision testing. Background Technology

[0002] Currently, many automakers have abandoned the use of NCM811 batteries and have set higher standards for power battery safety. With continuous technological advancements, new battery technologies not only improve driving range density but also place greater emphasis on safety.

[0003] There are many methods for testing battery safety, among which the power battery crash test is particularly crucial.

[0004] Currently, power battery crash tests typically involve directly fixing the battery pack onto the crash test platform. However, during crash tests, the battery may catch fire and pose other safety hazards. Fire extinguishers are generally used to put out the fire, but the lack of barriers during the process may endanger the surrounding environment and personal safety. Utility Model Content

[0005] This invention provides a fire extinguishing and protection device for simulating collision tests of power batteries, which can solve the problems pointed out in the background art.

[0006] A fire extinguishing and protection device for a power battery simulated collision test includes a water tank with several battery fixing positions inside the water tank. An insulating plate is provided below the bottom plate of the water tank, and several fixing holes are provided on the bottom plate to fix the water tank to the simulated collision platform through the fixing holes.

[0007] Preferably, the bottom of the water tank has a fixing frame, and the fixing frame is provided with a number of fixing plates with holes to form a number of battery fixing positions.

[0008] Preferably, a fixing bolt is fitted into the fixing hole, and an insulating pad and a metal pad are provided between the fixing bolt and the base plate.

[0009] Preferably, the water tank is connected to several lifting lugs.

[0010] Preferably, a plurality of positioning pins are provided between the base plate and the simulated collision platform.

[0011] Beneficial effects: This utility model provides a fire extinguishing and protection device for a power battery simulated collision test. If the battery smokes and catches fire during the test, water can be added to the pool to extinguish the fire, thus avoiding unnecessary harm. In addition, the water tank also acts as a barrier, which can avoid some unnecessary dangers. Attached Figure Description

[0016] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0017] Example 1: As Figure 1-2 As shown, a fire extinguishing and protection device for a power battery simulated collision test includes a water tank 1. The water tank 1 has several battery fixing positions. An insulating plate 2 is provided below the bottom plate 11 of the water tank 1. The bottom plate 11 has several fixing holes 12. The water tank 1 is fixed to the simulated collision platform 4 through the fixing holes 12. The insulating plate 2 can insulate the water tank from the simulated collision platform 4 and avoid unnecessary safety hazards.

[0018] Specifically, the bottom of the water tank 1 has a fixing frame 3, which has several fixing plates 31 with holes to form several battery fixing positions.

[0019] In some embodiments, the fixing bolt 13 is generally a metal bolt, and the water tank is a metal water tank. Therefore, in order to ensure the insulation between the water tank 1 and the simulated collision platform 4, the following structure is adopted: the fixing bolt 13 is connected in the fixing hole 12, and an insulating pad 14 and a metal pad 15 are provided between the fixing bolt 13 and the base plate 11.

[0020] In some embodiments, a plurality of lifting lugs 16 are connected to the water tank 1, which facilitates hoisting onto the simulated collision platform 4.

[0021] In some embodiments, a plurality of positioning pins 5 are provided between the base plate 11 and the simulated collision platform 4. The positioning pins 5 can quickly make the fixing holes 12 correspond to the fixing holes on the simulated collision platform 4, so as to facilitate the insertion of the fixing bolts 13.

[0022] If a fire or smoke occurs during the experiment, it can be extinguished by pouring water with a bucket, injecting water with a hose, or using a water gun. Water tank 1 is not only a water container but also serves as a barrier to avoid other unnecessary safety risks. Water tank 1 can be equipped with a drain outlet to prepare for the next test after the wastewater is discharged.

[0023] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
