[0016] The present invention hereby provides an automotive spare new energy battery storage device through improvement. Compared with the prior art, it has the following improvements and advantages:

[0017] First: When the lifting circular block does not fall, the first spring is in a compressed state.

[0018] Second: When the lifting circular block falls, the elastic potential energy stored by the compression of the first spring will be converted into mechanical energy, making the downward pressing speed of the lifting circular block and the trapezoidal squeezing block faster, so that the battery pack can be further away from the vehicle body, ensuring the safety of the vehicle occupants, and further improving the speed and safety.

[0019] Thirdly, the gravity of the storage box itself can make the battery pack move faster. After the battery pack moves to the right, it can automatically separate from the trapezoidal slider, which is fast and convenient, preventing the vehicle from still running over the discarded battery pack when moving forward or backward.

[0020] In summary, when the lifting round block does not fall, Spring 1 is in a compressed state. When the vehicle jolts on the road, the lifting plate and the storage box will reciprocally press down under the action of gravity, which can increase the air circulation speed between the outside air and the air inside the battery case, reducing the probability of the battery pack catching fire due to high temperature. When the lifting round block falls, the elastic potential energy stored in the compressed Spring 1 will be converted into mechanical energy, making the speed of the downward pressure of the lifting round block and the trapezoidal extrusion block faster, so that the battery pack can move further away from the vehicle body, ensuring the safety of the vehicle occupants, further improving the speed and safety. Due to the cooperation of the lifting plate and the storage box, it can not only increase the air circulation speed but also make the battery pack move further away from the vehicle body. And due to the gravity of the storage box itself, the battery pack can move faster. After the battery pack moves to the right, it can automatically separate from the trapezoidal slider, which is fast and convenient, preventing the vehicle from still running over the discarded battery pack when moving forward or backward.

Detailed implementation mode

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] Please refer to Figure 1 - Figure 7 , an embodiment of the present invention provides a technical solution: a storage device for an alternative new energy battery for an automobile, including a vehicle body 1 and a storage box 2 arranged in the vehicle body 1, and the storage box 2 is inserted into the bottom end of the vehicle body 1 in a vertically movable manner. A fixing frame 4 is fixedly connected to the bottom end of the vehicle body 1. A trapezoidal sliding block 72 is horizontally slidably arranged in the fixing frame 4. The bottom end of the trapezoidal sliding block 72 is connected to a connecting plate 8, and a battery case 3 is fixedly connected to the bottom end of the connecting plate 8. It further includes:

[0032] A heat dissipation mechanism 5, which can reduce the temperature in the inner cavity of the battery case 3 during driving, and the heat dissipation mechanism 5 is arranged in the vehicle body 1;

[0033] A limiting mechanism 6, which can timely separate the battery pack from the vehicle, and the limiting mechanism 6 is arranged in the trapezoidal sliding block 72;

[0034] And a transfer mechanism 7, which can throw the battery pack out from the side of the vehicle body 1, and the transfer mechanism 7 is arranged in the vehicle body 1.

[0035] Heat dissipation holes are formed in the side wall of the battery case 3, and a battery pack is placed in the battery case 3.

[0036] Specifically, when the lifting block 71 does not fall, the spring 1 53 is in a compressed state. When the vehicle bumps on the road, the lifting plate 52 and the storage box 2 will press downward reciprocatingly under the action of gravity, which can increase the circulation speed of the outer air and the air in the inner cavity of the battery shell 3, and reduce the probability of the battery pack spontaneously igniting due to high temperature. When the lifting block 71 falls, the elastic potential energy stored in the compressed spring 1 53 will be converted into mechanical energy, so that the lifting block 71 and the trapezoidal extrusion block 73 can be pressed down faster, so that the battery pack can be further away from the vehicle body 1, ensuring the safety of the people in the vehicle, and further improving the speed and safety. Due to the cooperation of the lifting plate 52 and the storage box 2, the air circulation speed can be increased, and the battery pack can be further away from the vehicle body 1. Due to the gravity of the storage box 2 itself, the battery pack can move faster. The battery pack can automatically detach from the trapezoidal slider 72 after moving to the right, which is quick and convenient, and prevents the vehicle from crushing the discarded battery pack when moving forward or reverse.

[0037] In another embodiment provided by the present invention, the heat dissipation mechanism 5 includes a lifting plate 52 that is slidably arranged in the vehicle body 1, a connecting rod 51 is connected between the upper end of the lifting plate 52 and the storage box 2, and the connecting rod 51 is slidably arranged in the vehicle body 1, a lifting round block 71 is provided on the lower side of the lifting plate 52, and a spring 53 is fixedly connected between the lifting round block 71 and the lifting plate 52, an insertion rod 54 is fixedly connected to the bottom end of the lifting plate 52, the bottom end of the insertion rod 54 extends into the trapezoidal slider 72, a trapezoidal block 55 is slidably connected to the bottom end of the insertion rod 54, and the trapezoidal block 55 is slidably arranged in the inner cavity of the trapezoidal slider 72, a slide plate 57 is slidably arranged on one side of the trapezoidal block 55 in the trapezoidal slider 72, and a pull rope 56 is connected between the upper end of the slide plate 57 and the trapezoidal block 55.

[0038] The sliding cavity where the sliding plate 57 is located is communicated with the inner cavity of the battery shell 3 .

[0039] Specifically, when the lifting block 71 does not fall, the spring 1 53 is in a compressed state. When the vehicle bumps on the road, the lifting plate 52 and the storage box 2 will be pressed downward reciprocatingly under the action of gravity, which can increase the circulation speed of the outside air and the air in the inner cavity of the battery shell 3, and reduce the probability of spontaneous combustion of the battery pack due to high temperature.

[0040] In another embodiment provided by the present invention, the limiting mechanism 6 includes a fixed retaining ring 61 located on the lower side of the lifting plate 52. The lower side of the fixed retaining ring 61 abuts against the lifting circular block 71. The bottom end of the trapezoidal block 55 is fixedly connected with a plug post 62. The bottom end of the plug post 62 is movably inserted into the trapezoidal slider 72. Trapezoidal plug blocks 63 are provided on both opposite sides of the plug post 62, and the trapezoidal plug blocks 63 are movably inserted into the trapezoidal slider 72. A second spring 65 is fixedly connected between the end of the trapezoidal plug block 63 away from the plug post 62 and the trapezoidal slider 72. A magnet 64 is provided in the trapezoidal slider 72 above the second spring 65. The bottom end of the trapezoidal plug block 63 is fixedly connected with a plug strip 67. A limiting frame 66 is sleeved on the outer side of the bottom end of the plug strip 67. A third spring 68 is fixedly connected between the bottom end of the plug strip 67 and the limiting frame 66. The end of the bottom end of the limiting frame 66 close to the plug post 62 is inserted into the connecting plate 8.

[0041] Specifically, when the lifting circular block 71 descends, the elastic potential energy stored by the compression of the first spring 53 will be converted into mechanical energy, making the descending speed of the lifting circular block 71 and the trapezoidal extrusion block 73 faster, so that the battery pack can move further away from the vehicle body 1, ensuring the safety of the vehicle occupants and further improving the speed and safety.

[0042] In another embodiment provided by the present invention, the transfer mechanism 7 includes a lifting circular block 71. The bottom end of the lifting circular block 71 is fixedly connected with a trapezoidal extrusion block 73. The bottom end of the trapezoidal extrusion block 73 is slidably connected with the trapezoidal slider 72. The bottom end of the lifting circular block 71 abuts against a stop block 74. One end of the stop block 74 is fixedly connected with the vehicle body 1 by a fourth spring 75. The end of the stop block 74 away from the trapezoidal extrusion block 73 abuts against a melting block 76, and a liquid storage cavity 77 is formed in the vehicle body 1 below the melting block 76.

[0043] The friction coefficient between the lifting circular block 71 and the stop block 74 is small.

[0044] The wires on the battery pack in the battery case 3 pass through the inner cavity of the fixing bracket 4. When the battery case 3 moves, the bottom end of the fixing bracket 4 can cut off the wires.

[0045] Specifically, the self-weight of the storage box 2 can make the battery pack move faster. The battery pack can move to the right and automatically disengage from the trapezoidal slider 72, which is fast and convenient, preventing the discarded battery pack from being run over when the vehicle moves forward or backward.

[0046] Working principle: Before the vehicle starts to move, the spare battery is first installed in the storage box 2. Then, during the driving, if the battery pack being used in the battery case 3 catches fire due to overheating or other reasons, the melting block 76 will melt due to the excessively high surrounding temperature. After that, the melting block 76 will flow into the liquid storage cavity 77. Due to the pulling of the spring four 75, the stop block 74 will contract towards the vehicle body 1, enabling the lifting round block 71 to drop. The dropping of the lifting round block 71 can cause the trapezoidal extrusion block 73 to move downward, thereby being able to squeeze the trapezoidal slider 72 to one side. The trapezoidal slider 72 drives the connecting plate 8 and the battery case 3 to move horizontally. Furthermore, when the subsequent battery pack is thrown out, it can be thrown out from one side of the vehicle bottom, preventing the vehicle from still rolling over the discarded battery pack when moving forward or backward, and preventing the continuous combustion of the battery pack from affecting the vehicle body 1 and the passengers in the vehicle;

[0047] It should be noted that when the lifting round block 71 does not drop, the spring one 53 is in a compressed state. When the vehicle jolts on the road, the lifting plate 52 will reciprocally press downward under the action of gravity. When the lifting plate 52 moves downward, the insertion rod 54 will squeeze the trapezoidal block 55 downward, enabling the trapezoidal block 55 to drive the sliding plate 57 to move upward through the pull rope 56. The sliding plate 57 moves upward and then will fall downward due to gravity. The reciprocating movement of the sliding plate 57 can increase the air circulation speed between the outside air and the air inside the battery case 3, further reducing the temperature of the battery pack during operation and reducing the probability of the battery pack catching fire due to high temperature;

[0048] When the lifting round block 71 drops, the lifting plate 52 and the spring one 53 will also drop due to the gravity of the storage box 2. At this time, the elastic potential energy stored in the compressed spring one 53 will be converted into mechanical energy, making the dropping speed of the lifting round block 71 and the trapezoidal extrusion block 73 faster. As a result, the trapezoidal slider 72, the connecting plate 8, the battery case 3, and the battery pack move to one side faster. After the fire, the battery pack can be separated from the vehicle faster, and the kinetic energy of the subsequent battery pack when it separates from the vehicle is greater. Thus, the battery pack can be farther away from the vehicle body 1, ensuring the safety of the passengers in the vehicle. It should be noted that when the temperature of the battery pack is too high, the passengers in the vehicle will be prompted by the system, so that they can timely drive the vehicle to a position close to the right side. Then, the battery pack will be thrown out to the right side, preventing the thrown battery pack from affecting other vehicles;

[0049] And due to the gravity of the storage box 2 itself, the moving speed of the battery pack can be faster, further improving the speed and safety;

[0050] When the battery case 3 and the battery pack move to the right, the lifting plate 52 will be blocked by the fixed retaining ring 61 when moving downward, but the lifting round block 71 will continue to move downward, so that the plug rod 54 and the trapezoidal block 55 will move upward relative to the trapezoidal slider 72, causing the plug post 62 to move upward. The trapezoidal plug block 63 and the limiting frame 66 will move away from the plug post 62 due to the elastic force of the second spring 65. When the limiting frame 66 moves to the directly lower side of the magnet 64, due to the magnetic force, the limiting frame 66 will automatically move upward, so that the limiting frame 66 can completely disengage from the connection plate 8, enabling the battery pack to move to the right and automatically disengage from the trapezoidal slider 72, which is fast and convenient.

[0051] During installation, first, the limiting mechanism 6 can limit the connection plate 8, then place the melting block 76 in the corresponding position, and then bolt the battery case 3 to the bottom end of the connection plate 8.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention.
