DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 12 The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it includes a positioning mechanism 6 for adjusting the position of the battery cell and enhancing the heat dissipation process; The explosion-proof mechanism 7 is used to monitor and cool down the temperature inside the battery pack; The three-sided closed door 2 has three sides, and a heat dissipation hole is opened on the center side; The housing 1 is used to house the battery and other components and is connected to the three closed doors 2. The interior of the housing 1 is divided into two cavities, the upper cavity is used to place a battery pack with high heat generation, and the lower cavity is used to place a battery pack with low heat generation; The reducer 4 has an inner diameter at one end close to the shell 1 smaller than that at the other end, and is connected to an external air blowing device; The end of the reducer 4 with a small inner diameter is fixedly connected with a plate 3, and the end of the plate 3 away from the reducer 4 is connected to the shell 1; in addition, the side of the shell 1 away from the three-sided closed door 2 is connected with a plate 3, and the other side of the plate 3 is connected to the reducer 4, and the other end of the reducer 4 is connected to the blasting device, so the wind generated by the blasting device will pass through the reducer 4 and the plate 3 in sequence until it enters the shell 1, wherein the gas enters the small diameter from the large diameter and will experience a rapid expansion process. According to the principles of thermodynamics, when the gas expands, it does work to the outside, the internal energy decreases, and the temperature decreases. This rapid expansion can significantly reduce the temperature of the gas in a short period of time, and can achieve the cooling purpose more quickly than some traditional cooling methods such as natural heat dissipation.

[0035] The end of the reducer 4 with a larger inner diameter is fixedly connected with a connecting sleeve 5 .

[0036] The positioning mechanism 6 includes a limiting bar 61, wherein the limiting bar 61 is fixedly mounted on the bottom of the cavity of the housing 1 and is used to limit the position of the battery pack and provide it with a support point; The bending plate 62 is used to limit the position of the deflected battery pack and is fixedly mounted on the top of the cavity of the housing 1; A battery body 63 is arranged inside the upper cavity of the shell 1, and an insertion hole 64 is opened on the outer side of the shell 1; the battery body 63 is placed into the upper cavity of the shell 1 through the insertion hole 64, wherein the interior of the shell 1 is divided into two upper and lower cavities, and the battery body 63 is a battery with strong heat generation capacity, and then one side of the battery body 63 will be tightly attached to the limit strip 61, and finally the three-sided closed door 2 is inserted into the interior of the shell 1 to realize the sealing treatment of the ring side of the shell 1.

[0037] The force applying block 65 is used to press the battery body 63 to make it slightly inclined and fit with the three-sided closed door 2; A temperature sensor 66 is installed inside the upper cavity of the shell 1, wherein the temperature sensor 66 is used to monitor the temperature inside the upper cavity of the shell 1; The block 67 gives the battery body 63 a suspended object and is fixedly connected to the bottom of the cavity of the housing 1; An embedded rail 68 is fixedly connected to the bottom of the upper cavity of the housing 1, and the inner cavity of the embedded rail 68 is slidably adapted to the force applying block 65; The electric push rod 69 is the source of power for the force applying block 65 and is controlled by the temperature sensor 66; The electric push rod 69 is fixedly connected to the inside of the embedded rail 68, and the outer end surface of the telescopic end of the electric push rod 69 is fixedly connected to the force block 65, and the outer side of the telescopic end of the electric push rod 69 is fixedly connected to the top inclined block 60; in addition, when the temperature inside the upper cavity of the shell 1 rises, the temperature sensor 66 will sense the temperature change. At this time, the temperature sensor 66 will drive the electric push rod 69 to start through the hub, wherein the fixed part of the electric push rod 69 is connected to the embedded rail 68, and the telescopic end of the electric push rod 69 is connected to the force block 65. With the start of the electric push rod 69, its telescopic end will carry the force block 65 through the three-sided closed door 2 and enter the interior of the shell 1 along the embedded rail 68, wherein the top of the force block 65 is sloped, and the height of one end of the force block 65 that initially enters the shell 1 is smaller than that of the other end. Height, so the end that initially enters the shell 1 will squeeze the bottom long side of the battery body 63, and the squeezed bottom long side of the battery body 63 will tend to move upward, but the other bottom long side of the battery body 63 is supported and limited by the limit bar 61, so the battery body 63 will deflect with the bottom long side close to the limit bar 61 as the fulcrum, and then the top long side of the battery body 63 will lean on the bending plate 62, causing the battery body 63 to be tilted, wherein the intermittent slight tilt placement slightly increases the contact area between the battery and the surrounding air, or changes the flow path of the hot air, reduces the accumulation of hot air around the battery, and is conducive to more effective heat dissipation to the surrounding environment through natural convection, thereby helping to reduce the battery temperature to a certain extent, and preventing the temperature from further rising and causing damage to the battery performance and life. The battery body 63 has a small tilt angle, so there will be no problems such as electrolyte leakage and damage to the internal structure of the battery.

[0038] The top of the housing 1 is sleeved with an insertion rod 602; The trapezoidal block 601 is used for the outward movement of the force applying block 65 and the passive extension of the telescopic end of the electric push rod 69, and is fixedly connected to the bottom end of the penetration rod 602; The inclined surface at the bottom of the trapezoidal block 601 is pressed and adapted to the top of the top inclined block 60. The cross beam plate 74 moves downward, so that the insertion rod 602 fixedly connected to the bottom thereof will move downward with the trapezoidal block 601 until the trapezoidal block 601 presses the top inclined block 60, and the pressed top inclined block 60 will extend outward with the electric push rod 69, and finally the force block 65 connected to the electric push rod 69 will extend outward from the housing 1, so that the battery body 63 remains horizontal again, thereby preventing the battery body 63 from remaining tilted when the temperature is too high or during fire, causing the electrolyte to overflow.

[0039] like Figure 8 and Fig. 9As shown, the explosion-proof mechanism 7 includes a support rod 71, a limit assembly 72 is provided at the bottom of the support rod 71, a cross beam plate 74 is fixedly connected to the top of the support rod 71, and a fixed shaft 75 is fixedly connected inside the cross beam plate 74; The hollow rotating plate 76 is used for storing and processing the dry powder fire extinguishing agent, and is rotatably connected to the fixed shaft 75; the inner cavity of the hollow rotating plate 76 is sealed with a membrane to prevent the dry powder fire extinguishing agent from accidentally spilling or getting wet, and when the temperature inside the shell 1 is too high, the membrane will rupture due to the heat.

[0040] An L-shaped plate 78 is fixedly connected to the top of the crossbeam plate 74; A reset spring 77 is used to reset the hollow rotating plate 76 and is connected to the top of the hollow rotating plate 76; The top end of the return spring 77 is fixedly connected to the L-shaped plate 78; The top round rod 73 is pressed and matched with the hollow rotating plate 76 to deflect the hollow rotating plate 76 , and is fixedly connected to the top of the housing 1 .

[0041] like Fig.10 , Fig.11 and Fig.12 As shown, the limiting assembly 72 includes a hollow block 721, which is fixedly connected to the inner side of the housing 1, and the central part of the hollow block 721 is sleeved and matched with the support rod 71; A fitting block 727 is disposed inside the hollow block 721; The limiting plate 726 is used for limiting and locking the support rod 71, and the top of the limiting plate 726 is pressed and matched with the fitting block 727; The outer side of the hollow block 721 is fixedly connected with a round cake block 722, the top of the round cake block 722 is fixedly connected with a support rod 723, and one end of the support rod 723 away from the round cake block 722 is fixedly connected with a support shaft seat 724; The telescopic rotating plate 725 is used to release the limiting treatment of the support rod 71 by the limiting plate 726, and the top of the telescopic rotating plate 725 is rotatably connected to the support shaft seat 724; A spring 728 is fixedly connected to the outer side of the telescopic rotating plate 725, and one end of the spring 728 away from the telescopic rotating plate 725 is fixedly connected to the hollow block 721; The capsule 729 is used to limit the telescopic rotating plate 725 and is fixedly connected to the outer side of the hollow block 721; the telescopic rotating plate 725, which was originally limited by the capsule 729, will be free, and under the tensile elastic force of the spring 728, it will deflect outward with the support shaft seat 724 as the fulcrum, and the telescopic end of the telescopic rotating plate 725 is connected to the plug-in plate 726, so the plug-in plate 726 will extend outward from the inside of the support rod 71, and the fitting block 727 will no longer squeeze the plug-in plate 726. Therefore, as the plug-in plate 726 extends outward, the support rod 71 will pass through the hollow block 721 and move downward, wherein the support rod 71 The top end is connected to the cross beam plate 74, and the interior of the cross beam plate 74 is fixedly connected to a fixed shaft 75, and the outer side of the fixed shaft 75 is rotatably connected to a hollow rotating plate 76, so the hollow rotating plate 76 will also move downward accordingly, wherein the top of the shell 1 is fixedly connected to a top round rod 73, and as the hollow rotating plate 76 moves downward, the outer end of the hollow rotating plate 76 will be squeezed by the top round rod 73, causing the hollow rotating plate 76 to deflect downward through the fixed shaft 75, and then the dry powder fire extinguishing agent stored in the hollow rotating plate 76 will be thrown out and sprinkled on the battery body 63, thereby playing a role in forced cooling and fire extinguishing of the battery body 63.

[0042] The top of the capsule 729 is squeezed and adapted with the telescopic rotating plate 725, and the two ends of the capsule 729 are symmetrically connected with the air pipe 720, wherein the interior of the capsule 729 and the air pipe 720 are filled with gas. In addition, as the electric push rod 69 contracts, the top inclined block 60 fixedly connected to its telescopic end will be directly below the trapezoidal block 601. If the temperature of the battery body 63 is still not effectively reduced and there is a tendency to catch fire, the capsule 729 in the upper cavity of the shell 1 will rupture, wherein the capsule 729 is a tough capsule made of plastic material, which is connected to the air pipe 720, and both are filled with gas, wherein the function of the air pipe 720 is that when any one of the capsules 729 is ruptured by heat, the air pipe 720 will discharge the gas inside the remaining capsules 729 to the outside, causing the plurality of support rods 71 ​​to move downward.

[0043] When the present invention is in use: first, the battery body 63 is placed into the upper cavity of the shell 1 through the insertion hole 64, wherein the interior of the shell 1 is divided into two upper and lower cavities, and the battery body 63 is a battery with a strong heat generation capacity, and then one side of the battery body 63 will be tightly attached to the limit strip 61, and finally the three-sided closed door 2 is inserted into the shell 1 to achieve the sealing treatment of the ring side of the shell 1. In addition, the side of the shell 1 away from the three-sided closed door 2 is connected to the plate 3, and the other side of the plate 3 is connected to the reducer 4, and the other end of the reducer 4 is connected to the blasting device, so the wind generated by the blasting device will pass through the reducer 4 and the plate 3 in turn until it enters the shell 1, so as to achieve heat dissipation treatment of the battery body 63 inside the shell 1. In addition, when the temperature inside the cavity of the shell 1 rises, the temperature sensor 66 will sense the temperature change. At this time, the temperature sensor 66 will drive the electric push rod 69 to start through the hub, wherein the fixed part of the electric push rod 69 is connected to the embedded rail 68, and the telescopic end of the electric push rod 69 is connected to the force block 65. As the electric push rod 69 is started, its telescopic end will carry the force block 65 through the three-sided closed door 2 and enter the interior of the shell 1 along the embedded rail 68. The top of the force block 65 is sloped, and the force block 65 is The height of one end that initially enters the shell 1 is smaller than the height of the other end, so the one end that initially enters the shell 1 will squeeze the bottom long side of the battery body 63, and the squeezed bottom long side of the battery body 63 will tend to move upward, but the other bottom long side of the battery body 63 is supported and limited by the limit bar 61, so the battery body 63 will deflect with the bottom long side close to the limit bar 61 as the fulcrum, and then the top long side of the battery body 63 will lean against the bent plate 62, causing the battery body 63 to be in an inclined state to increase the heat dissipation effect.

[0044] In addition, as the electric push rod 69 contracts, the top inclined block 60 fixedly connected to its telescopic end will be directly below the trapezoidal block 601. If the temperature of the battery body 63 is still not effectively reduced and there is a tendency to catch fire, the capsule 729 inside the upper cavity of the shell 1 will rupture, and the telescopic rotating plate 725, which was originally limited by the capsule 729, will be free, and under the tensile elastic force of the spring 728, it will deflect outward with the support shaft seat 724 as the fulcrum. The telescopic end of the telescopic rotating plate 725 is connected to the plug-in plate 726, so the plug-in plate 726 will extend outward from the inside of the support rod 71, and the fitting block 727 will no longer squeeze the plug-in plate 726. Therefore, as the plug-in plate 726 extends outward, the support rod 71 will pass through the hollow block 721 and move downward. The top end of the support rod 71 is connected to the cross beam 74, and the interior of the cross beam 74 is fixedly connected to a fixed shaft 75, and the outer side of the fixed shaft 75 is rotatably connected to a hollow rotating plate 76, so the hollow rotating plate 76 will also move downward accordingly, wherein the top of the shell 1 is fixedly connected to a top round rod 73, as the hollow rotating plate 76 moves downward, the outer end of the hollow rotating plate 76 will be squeezed by the top round rod 73, causing the hollow rotating plate 76 to deflect downward through the fixed shaft 75, and then the dry powder fire extinguishing agent stored in the hollow rotating plate 76 will be thrown out and sprinkled on the battery body 63 to achieve forced cooling or fire extinguishing treatment.

[0045] Through the downward movement of the crossbeam plate 74, the inserted rod 602 fixedly connected to the bottom thereof will move downward with the trapezoidal block 601 until the trapezoidal block 601 squeezes the top inclined block 60, and the squeezed top inclined block 60 will extend outward with the electric push rod 69, and finally the force block 65 connected to the electric push rod 69 will extend outward from the shell 1, causing the battery body 63 to remain in a horizontal state again.

[0046] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
