[0056] Next, in combination with the accompanying drawings and the detailed implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features, and it should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Please refer to Figures 1 to 12 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , it includes a position adjusting mechanism 6 for adjusting the position of the battery cells and strengthening heat dissipation treatment;

[0058] An explosion-proof mechanism 7 for monitoring and cooling the temperature inside the battery pack;

[0059] A three-sided closed door 2 with three sides and heat dissipation holes opened on the central plane;

[0060] A housing 1 providing a placement place for the battery and other components and sleeved with the three-sided closed door 2;

[0061] The interior of the housing 1 is divided into upper and lower cavities, and the upper cavity is used for placing the battery pack with large heat generation, while the lower cavity is used for placing the battery pack with small heat generation;

[0062] A reducing pipe 4 with an inner diameter at one end close to the housing 1 smaller than that at the other end and connected to an external air blowing device;

[0063] 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;

[0064] The end of the reducer 4 with a larger inner diameter is fixedly connected with a connecting sleeve 5 .

[0065] 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;

[0066] 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;

[0067] 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.

[0068] 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;

[0069] 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;

[0070] 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;

[0071] 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;

[0072] The electric push rod 69 is the source of power for the force applying block 65 and is controlled by the temperature sensor 66;

[0073] The electric push rod 69 is fixedly connected inside the embedded rail 68. The outer end face of the telescopic end of the electric push rod 69 is fixedly connected to the force application block 65, and a top inclined block 60 is fixedly connected to the outside of the telescopic end of the electric push rod 69. Additionally, when the temperature inside the upper cavity of the housing 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 central control. 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 application block 65. With the start of the electric push rod 69, its telescopic end will drive the force application block 65 to pass through the three-sided closing door 2 and enter the inside of the housing 1 along the embedded rail 68. The top of the force application block 65 is in a slope shape, and the height of the end initially entering the inside of the housing 1 is less than that of the other end. Therefore, the end initially entering the inside of the housing 1 will squeeze the bottom long side of the battery body 63, and the bottom long side of the battery body 63 being squeezed will tend to move upward. However, the other bottom long side of the battery body 63 is supported and limited by the limiting strip 61. Therefore, the battery body 63 will deflect with the bottom long side close to the limiting strip 61 as the fulcrum. Immediately afterwards, the top long side of the battery body 63 will lean against the bending plate 62, causing the battery body 63 to present an inclined state. The intermittent slight inclination placement slightly increases the contact area between the battery and the surrounding air, or changes the flow path of the hot air, reducing the accumulation of hot air around the battery, which is beneficial to the heat being more effectively dissipated 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 damaging the battery performance and life. The inclination angle of the battery body 63 is small, so problems such as electrolyte leakage and damage to the internal structure of the battery will not occur.

[0074] The top of the housing 1 is sleeved with an insertion rod 602;

[0075] The trapezoidal block 601 is used for the outward movement of the force application block 65 and the passive elongation treatment of the telescopic end of the electric push rod 69, and is fixedly connected to the bottom end of the insertion rod 602;

[0076] The inclined surface part at the bottom of the trapezoidal block 601 is in extrusion fit with the top of the top inclined block 60. Through the downward movement of the cross beam plate 74, the insertion rod 602 fixedly connected to its bottom will drive the trapezoidal block 601 to move downward until the trapezoidal block 601 squeezes the top inclined block 60, and the top inclined block 60 being squeezed will drive the electric push rod 69 to extend outward. Finally, the force application block 65 connected to the electric push rod 69 will extend outward from the inside of the housing 1, causing the battery body 63 to return to a horizontal state, thereby playing a role in preventing the electrolyte from overflowing outward when the battery body 63 has too high a temperature or catches fire and it still remains in an inclined state.

[0077] Such as Figure 8 And Figure 9As shown, the explosion-proof mechanism 7 includes a support rod 71. A limit component 72 is arranged at the bottom of the support rod 71. The top end of the support rod 71 is fixedly connected with a cross beam plate 74. A fixed shaft 75 is fixedly connected inside the cross beam plate 74;

[0078] A hollow rotating plate 76, used for storing and processing dry powder fire extinguishing agent, is rotatably connected to the fixed shaft 75; wherein the inner cavity of the hollow rotating plate 76 is sealed by a film to prevent the accidental spillage or moisture absorption of the dry powder fire extinguishing agent. When the temperature inside the housing 1 is too high, the film will be heated and broken.

[0079] An L-shaped plate 78 is fixedly connected to the top of the cross beam plate 74;

[0080] A return spring 77, used for resetting the hollow rotating plate 76, is connected to the top of the hollow rotating plate 76;

[0081] The top end of the return spring 77 is fixedly connected to the L-shaped plate 78;

[0082] A top round rod 73, which is in extrusion fit with the hollow rotating plate 76 to cause the hollow rotating plate 76 to deflect, is fixedly connected to the top of the housing 1.

[0083] As Figure 10 、 Figure 11 and Figure 12 shown, the limit component 72 includes a hollow block 721. The hollow block 721 is fixedly connected to the inner side of the housing 1. The central part of the hollow block 721 is sleeved and adapted to the support rod 71;

[0084] A fitting block 727 is arranged inside the hollow block 721;

[0085] An insertion limit plate 726, used for limiting and locking the support rod 71, and its top is in extrusion fit with the fitting block 727;

[0086] A round cake block 722 is fixedly connected to the outside of the hollow block 721. A support bent rod 723 is fixedly connected to the top of the round cake block 722. One end of the support bent rod 723 far from the round cake block 722 is fixedly connected to a support shaft seat 724;

[0087] A telescopic rotating plate 725, used for releasing the limit of the support rod 71 by the insertion limit plate 726, and its top is rotatably connected to the support shaft seat 724;

[0088] A spring 728 is fixedly connected to the outside of the telescopic rotating plate 725. One end of the spring 728 far from the telescopic rotating plate 725 is fixedly connected to the hollow block 721;

[0089] The bladder 729 is used for limiting the telescopic rotating plate 725 and is fixedly connected to the outside of the hollow block 721. The telescopic rotating plate 725, which was originally limited by the bladder 729, will become free and deflect outward with the stretching elastic force of the spring 728 with the support pivot seat 724 as the fulcrum. The telescopic end of the telescopic rotating plate 725 is connected to the insertion limiting plate 726. Therefore, the insertion limiting plate 726 will extend outward from the inside of the support rod 71. At the same time, the fitting block 727 will no longer squeeze the insertion limiting plate 726. Therefore, as the insertion limiting plate 726 extends outward, the support rod 71 will pass through the hollow block 721 and move downward. The top of the support rod 71 is connected to the cross beam plate 74, and a fixed shaft 75 is fixedly connected inside the cross beam plate 74. A hollow rotating plate 76 is rotatably connected to the outside of the fixed shaft 75. Therefore, the hollow rotating plate 76 will also move downward accordingly. A top round rod 73 is fixedly connected to the top of the housing 1. 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. Immediately afterwards, the dry powder fire extinguishing agent stored inside the hollow rotating plate 76 will be scattered and sprinkled on the battery body 63, thereby playing a role in forcibly cooling and extinguishing the battery body 63.

[0090] The top of the bladder 729 is in extrusion fit with the telescopic rotating plate 725. Air pipes 720 are symmetrically connected to both ends of the bladder 729. Gas is filled inside both the bladder 729 and the air pipes 720. Additionally, 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 still cannot be effectively reduced and shows a trend of catching fire, at this time, the bladder 729 inside the upper cavity of the housing 1 will rupture. The bladder 729 is a ductile bladder made of plastic material. It is connected to the air pipes 720, and gas is filled inside both of them. The function of the air pipes 720 is that when any one of the bladders 729 is heated and ruptured, the air pipes 720 will export the gas inside the remaining bladders 729 outward, causing all the support rods 71 to move downward.

[0091] When the present invention is in use: First, the battery body 63 is placed into the upper cavity of the housing 1 through the insertion hole 64. The interior of the housing 1 is divided into upper and lower cavities, and the battery body 63 is a battery with relatively strong heat generation ability. Immediately afterwards, one side of the battery body 63 will closely adhere to the limiting strip 61. Finally, the three-sided closed door 2 is inserted into the interior of the housing 1 to achieve the closed treatment of the circumferential side of the housing 1. In addition, a attaching plate 3 is connected to the side of the housing 1 away from the three-sided closed door 2, and the other side of the attaching plate 3 is connected to the variable-diameter pipe 4. In addition, the other end of the variable-diameter pipe 4 is connected to the air-blowing device. Therefore, the wind generated by the air-blowing device will sequentially pass through the variable-diameter pipe 4 and the attaching plate 3 and then enter the housing 1 to achieve the heat dissipation treatment of the battery body 63 inside the housing 1. In addition, when the temperature inside the upper cavity of the housing 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 central control. 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-applying block 65. With the start of the electric push rod 69, its telescopic end will drive the force-applying block 65 to pass through the three-sided closed door 2 and enter the interior of the housing 1 along the embedded rail 68. The top of the force-applying block 65 is in a slope shape, and the height of the end that initially enters the interior of the housing 1 is less than the height of the other end. Therefore, the end that initially enters the housing 1 will squeeze the bottom long side of the battery body 63, and the bottom long side of the battery body 63 that is squeezed will tend to move upward. However, the other bottom long side of the battery body 63 is supported and limited by the limiting strip 61. Therefore, the battery body 63 will deflect with the bottom long side close to the limiting strip 61 as the fulcrum. Immediately afterwards, the top long side of the battery body 63 will lean against the bending plate 62, causing the battery body 63 to present an inclined state to increase the heat dissipation effect.

[0092] 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 still has not been effectively reduced and shows a tendency to catch fire, the bladder 729 inside the upper cavity of the housing 1 will rupture at this time, and the telescopic rotating plate 725 originally fitted and limited by the bladder 729 will become 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 insertion limiting plate 726, so the insertion limiting plate 726 will extend outward from the inside of the support rod 71. At the same time, the fitting block 727 no longer squeezes the insertion limiting plate 726. Therefore, as the insertion limiting plate 726 extends outward, the support rod 71 will pass through the hollow block 721 and move downward. The top of the support rod 71 is connected to the cross beam plate 74, and a fixed shaft 75 is fixedly connected inside the cross beam plate 74, and a hollow rotating plate 76 is rotatably connected to the outside of the fixed shaft 75. Therefore, the hollow rotating plate 76 will also move downward accordingly. A top round rod 73 is fixedly connected to the top of the housing 1. 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. Immediately afterwards, the dry powder fire extinguishing agent stored inside the hollow rotating plate 76 will be scattered and sprinkled on the battery body 63 to achieve forced cooling or fire extinguishing treatment for it.

[0093] As the cross beam plate 74 moves downward, the insertion rod 602 fixedly connected to its bottom will drive the trapezoidal block 601 to move downward until the trapezoidal block 601 squeezes the top inclined block 60, and the squeezed top inclined block 60 will drive the electric push rod 69 to extend outward. Finally, the force applying block 65 connected to the electric push rod 69 will extend outward from the housing 1, causing the battery body 63 to return to a horizontal state again.

[0094] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts and without creative labor, all kinds of transformations made fall within the scope of protection of the present invention.
