The inner wall of the tray 1 is provided with a first through pipe 2116. The number of the first through pipe 2116 is several. The first through pipe 2116 is fixedly connected to the top of the partition cavity 2114. The first through pipe 2116 The other end is fixedly connected to the inner cavity of the liquid-cooling cavity plate 2115, a protective box 2117 is fixedly installed on the top of each fire-resistant plate 2104, the number of protective boxes 2117 is several, the inner wall of each protective box 2117 is fixedly connected with a micro switch 2118, the micro switch 2118 is electrically connected to the micro liquid-gas dual-purpose pump 2107 through a connecting wire, the bottom of the partition 2103 is fixedly connected with a guide rod 2119, the number of guide rods 2119 is several, the surface of every two guide rods 2119 is slidably sleeved with a guide plate 2120, the surface of the guide plate 2120 is fixedly connected with a hanging ring 2121, the inner wall of the hanging ring 2121 is in contact with the temperature-sensitive glass ball of the closed fine water mist nozzle 2110 and is sleeved on the surface of the temperature-sensitive glass ball,A top rod 2122 is fixedly connected to the surface of the guide plate 2120, one end of the top rod 2122 penetrates the top of the partition 2103, one end of the top rod 2122 penetrates the top of the fireproof board 2104 and extends to the inner cavity of the protection box 2117, the top rod 2122 is used in conjunction with the micro switch 2118, and a tension spring 2123 is fixedly connected to the bottom of the partition 2103, the tension spring 2123 is sleeved on the surface of the top rod 2122, and one end of the tension spring 2123 is fixedly connected to the surface of the guide plate 2120.

[0043] The specific implementation of this embodiment is as follows: when the battery module 4 has an abnormal temperature, it is easy to spontaneously combust. The excessively high temperature will open the closed fine water mist nozzle 2110. The closed fine water mist nozzle 2110 is a prior art. The closed fine water mist nozzle 2110 is a nozzle specially used to produce fine water mist particles. Under normal working conditions, the nozzle is in a closed state, and the internal water flow is sealed. When the temperature rises to the set action temperature, the temperature sensing element is activated, so that the sealing structure inside the nozzle is destroyed, and the temperature sensing glass ball is broken. At this time, it is affected by the tension of the tension spring 2123, and the hanging ring 2121 loses its limit. The broken glass ball is not enough to support the tension of the hanging ring 2121 and the tension spring 2123, and the guide plate 2 is pulled at this time. 120 slides upward on the surface of the guide rod 2119.

Since the micro switch 2118 is electrically connected to the micro liquid-gas dual-purpose pump 2107 through the connecting wire, when the micro switch 2118 is touched and turned on, the micro liquid-gas dual-purpose pump 2107 is started at the same time. The micro liquid-gas dual-purpose pump 2107 is a prior art and will not be described in detail here. The micro liquid-gas dual-purpose pump 2107 can pass the inert gas through the annular tube 2108 and the delivery tube 2109. It is sprayed out through the closed fine water mist nozzle 2110, and what is sprayed out at this time is inert gas. After the inert gas in the inert gas storage tank 2105 is discharged, the micro liquid-gas dual-purpose pump 2107 will continue to operate, and in conjunction with the suction tube 2111, the coolant in the cooling system of the battery tray 1 can be pumped into the inert gas storage tank 2105, and sprayed into the battery tray 1 through the closed fine water mist nozzle 2110. The formed water mist can further prevent the burning and spread of the flame. By setting the frame cover 2101 and the isolation plate 2102, the fire protection unit 21 can be divided into several groups, and the battery module 4 that spontaneously combusts can be individually fire-fighting and extinguishing. By setting the partition 2103, the frame cover 2101 and the isolation plate 2102 can be fixed. The inert gas storage tank 2105 can be fixed, and the frame cover 2101 and the isolation plate 2102 made of refractory materials can further increase the fire prevention effect. When the suction pipe 2111 draws out the coolant, a one-way valve 2112 is set. The one-way valve 2112 is a prior art. The one-way valve 2112 is also called a check valve or a non-return valve. It is an automatic valve that allows a medium such as liquid, gas or solid particles to flow in one direction while preventing the flow in the opposite direction to prevent the suction pipe 2111 from leaking and backflowing when not in use. By setting a cooling groove 2113 and a partition chamber 2114, the coolant drawn through the cooling protection unit 22 will enter the cooling groove 2113 and the partition chamber 2114 for circulation cooling.The cooling liquid circulating in the cooling groove 2113 and the partition chamber 2114 will enter the liquid cooling chamber plate 2115 through the first through pipe 2116. At this time, the liquid cooling chamber plate 2115 can cool the battery module 4. The first through pipe 2116 is a hose.

[0045] As a further limitation of the safety mechanism 2 of the present invention, the cooling protection unit 22 includes a fixed box 2201, which is fixedly connected to one side of the tray 1. One side of the fixed box 2201 is fixedly connected to an interface 2202, and the number of interfaces 2202 is two.

The water inlet pipe and the water outlet pipe connected by the water pump are fixedly connected to the lower layer and the upper layer of the cooling groove 2113 respectively. By setting the second through pipe 2204, the coolant in the liquid-cooling cavity plate 2115 can be transported back to the upper layer of the cooling groove 2113, and drawn out through the water outlet pipe connected to the water pump to complete the circulation.

[0047] A through slot 2205 is provided between each cooling slot 2113, and a second layer plate 2206 is fixedly connected to the inner wall of the through slot 2205. The second layer plate 2206 is fixedly connected to the first layer plate 2203, and the second layer plate 2206 divides the through slot 2205 into two layers, an upper layer and an lower layer. By setting the through slot 2205, the cooling slots 2113 can be connected to each other, so that the coolant can flow therein conveniently. The through slot 2205 can be divided into two layers, an upper layer and an lower layer, and connected to the upper layer and the lower layer divided by the cooling slot 2113 through the second layer plate 2206.

There are two inert gas storage boxes 2207. By setting a sealed inert gas storage box 2207 made of aluminum, it is convenient to store the inert gas.

[0049] The lower inner walls of the two cooling grooves 2113 are fixedly connected with plug rods 2208. There are four plug rods 2208, which penetrate the inner wall of the partition chamber 2114. The interior of the plug rods 2208 is provided with through holes. The sharp ends of each two plug rods 2208 are respectively in contact with the surface of one of the inert gas storage boxes 2207. When the side of the vehicle is hit, the inert gas storage box 2207 in the partition chamber 2114 is broken forward by the impact of the plug rods 2208, so that the inert gas can be released immediately, thereby reducing the risk of spontaneous combustion of the battery module 4 caused by the impact.

[0050] The specific implementation of this embodiment is as follows: the coolant in the cooling system of the battery tray 1 can be pumped into the cooling tank 2113 and the partition chamber 2114 through the water pump and the interface 2202, further enhancing the overall cooling effect of the battery tray 1; the cooling tank 2113 can be divided into an upper and lower layer by setting a first layered plate 2203; the two interfaces 2202 are respectively connected to the water inlet pipe and the water outlet pipe of the water pump; the two interfaces 2202 are respectively fixedly connected to the lower layer and the upper layer of the cooling tank 2113 through the water inlet pipe and the water outlet pipe; the second through-pipe 2204 is provided, so that the coolant in the liquid-cooling cavity plate 2115 can be transported back to the upper layer of the cooling tank 2113 and pumped out by the water pump to complete the circulation; The through slot 2205 can achieve connectivity between the cooling slots 2113, facilitating the circulation of coolant therein; the through slot 2205 can be divided into two layers, upper and lower layers, by the second layered plate 2206, and connected to the upper and lower layers of the cooling slot 2113; a sealed inert gas storage box 2207 made of aluminum is provided to facilitate the storage of inert gas; when the side of the vehicle is hit, the tray 1 will also be hit, and the side of the tray 1 will be deformed due to the impact, which will cause the rod 2208 to break the inert gas storage box 2207 in the partition chamber 2114 forward, thereby releasing the inert gas in the first place, thereby reducing the risk of spontaneous combustion of the battery module 4 due to the impact.

[0051] Example 3: Please refer to Figure 1-Figure 15 The present invention provides a technical solution: a battery tray that can improve the safety of automobile batteries.

By setting the placement boxes 301, the positions of the battery modules 4 can be fixed, so that when the vehicle is hit, the battery modules 4 in the placement boxes 301 can be displaced to a certain extent in the battery tray 1, thereby reducing the extrusion between the battery modules 4 and having a certain degree of buffering effect, thereby avoiding the phenomenon that the battery modules 4 are clustered and spontaneously combusted after being hit and squeezed.

[0053] The inner wall of the tray 1 is provided with sliding grooves 302, and the number of the sliding grooves 302 corresponds to the number of the placement boxes 301.

The size of the sliding plate 303 is smaller than the inner cavity size of the sliding groove 302. By setting the sliding grooves 302 and the sliding plates 303, the sliding plates 303 slide in the sliding grooves 302 to achieve a certain degree of displacement of the placement boxes 301.

[0054] The top of each sliding plate 303 is fixedly connected to a fixing column 304, the top of the fixing column 304 is fixedly connected to the bottom of the placement box 301, and the surface of each placement box 301 is fixedly connected to a strong damping spring 305.
