[0038] A leak-proof sheet 488 is fixedly connected to the top of the cooling tube 3, and a force-bearing plate 489 is fixedly connected to one end of the leak-proof sheet 488 away from the cooling tube 3, wherein there are two leak-proof sheets 488, which are symmetrically connected on both sides of the cooling tube 3, and the force-bearing plate 489 is slidably adapted on the top of the cooling tube 3, and a return spring 480 is fixedly connected to the outer side of the force-bearing plate 489, and one end of the return spring 480 away from the force-bearing plate 489 is fixedly connected to a vertical plate 4801, and the vertical plate 4801 is fixedly connected to the top of the cooling tube 3, and two ends of the force-bearing plate 489 are symmetrically connected to connecting rods 4807, and one end of the connecting rod 4807 away from the force-bearing plate 489 is fixedly connected to a double-headed rod 4808, and one end of the double-headed rod 4808 away from the connecting rod 4807 is fixedly connected to the outer side of the blocking plate 483, and when the coolant flows in the cooling tube 3 and passes through the annular sleeve 481, the cooling tube 3 will periodically The force-bearing plate 489 is impacted, and the impacted force-bearing plate 489 moves outward along the top of the cooling tube 3, and compresses and stretches the leak-proof sheets 488 fixedly connected on both sides thereof, respectively, wherein the leak-proof sheets 488 prevent the coolant from overflowing outward, wherein both ends of the force-bearing plate 489 are fixedly connected with connecting rods 4807, and the other end of the connecting rod 4807 is fixedly connected with a double-headed rod 4808, so as the double-headed rod 4808 moves outward, the blocking plate 483 fixedly connected to the other end thereof will move forward along the inner rail 482, and the small radiator 484 originally blocked by the blocking plate 483 will be exposed, and at this time the small radiator 484 will cool down the coolant whose temperature rises after heat exchange, and at the same time, it also keeps the coolant at a low temperature, and continuously cools down the battery module.

[0039] The bottom of the cooling tube 3 is fixedly connected with a dredging tube 4803, the bottom of the dredging tube 4803 is fixedly connected with a folded tube 4804, the folded tube 4804 is fixedly connected to the bottom of the ring sleeve 481, one end of the folded tube 4804 away from the dredging tube 4803 is fixedly connected to the outside of the No. 1 double-pass plate 485, the top of the dredging tube 4803 is fixedly connected with a support 4805, the inside of the support 4805 is rotatably connected with a one-way plate 4806 through a rotating shaft, wherein the one-way plate 4806 can only be deflected inwardly under force, but cannot be deflected outwardly, and when the coolant is lost after a wave of impact force, the force-bearing plate 489 will return to its original position under the elastic force of the return spring 480, but at this time part of the coolant will be in the return of the force-bearing plate 489. During the process, the cooling water flows in the reverse direction, and the cooling water flowing in the reverse direction will impact the one-way plate 4806. At this time, the one-way plate 4806 that is impacted will be deflected inward through the support 4805, causing the cooling water flowing in the reverse direction to pass through the one-way plate 4806 and enter the dredging pipe 4803. The other end of the dredging pipe 4803 is connected to the No. 1 double-pass plate 485. Therefore, part of the cooling water flowing in the reverse direction and the cooling water flowing forward will be divided into two paths, and finally meet in the No. 1 double-pass plate 485 until they enter the cooling pipe 3 together, thereby leading away the cooling water flowing in the reverse direction to avoid colliding with the cooling water flowing in the forward direction and affecting the subsequent cooling progress and flow progress.

[0040] like Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the protective mechanism 5 includes a support frame 51, the support frame 51 is fixedly connected to the outside of the shell 1, the side of the support frame 51 away from the shell 1 is fixedly connected to a slide bar 52, the end of the slide bar 52 away from the support frame 51 is slidably adapted to be equipped with a pressure block 53, the pressure block 53 is inserted into the outside of the support frame 51 and extends to the inside, the support frame 51 is provided with an inner liner air cushion 501, the side of the inner liner air cushion 501 away from the support frame 51 is fixedly connected to a double-way square tube 50, wherein the double-way square tube 50 is respectively inserted into the inside of the support frame 51 and the shell 1, and the end of the double-way square tube 50 away from the inner liner air cushion 501 is fixedly connected to the inner protective air cushion 501. 4. The inner air cushion 54 is arranged inside the shell 1. The inner part of the inner air cushion 501 is fixedly connected with a hollow frame 59. Both ends of the inner cavity of the inner air cushion 501 are fixedly connected with vertical rails 55. The inner part of the vertical rails 55 is fixedly connected with friction protrusions 56. The inner sliding part of the vertical rails 55 is adapted with a force reduction plate 57. The outer side of the force reduction plate 57 is extruded and adapted with the friction protrusions 56. The bottom of the force reduction plate 57 is fixedly connected with a damper 58. The support frame 51 not only supports the shell 1 and the battery module, but also plays a first-level protection role against external impact force. When the battery module is subjected to strong external impact and collision, the pressure block 53 The inner liner air cushion 501 is arranged inside the support frame 51, and the inner liner air cushion 501 is filled with gas, so the pressure block 53 will squeeze the inner liner air cushion 501. At this time, the part of the inner liner air cushion 501 that contacts the pressure block 53 will be compressed, and the lower part will expand. Therefore, the gas will surge downward and squeeze the force reducing plate 57 downward. At this time, the force reducing plate 57 will move downward along the vertical rail 55, and the friction protrusion 56 fixedly connected to the inside of the vertical rail 55 will increase the friction between the force reducing plate 57 and the vertical rail 55. The friction force between the vertical rails 55 will increase due to the friction protrusions 56, causing a portion of the compression force of the gas inside the inner liner air cushion 501 to be converted into the friction force between the force reducing plate 57 and the friction protrusions 56, thereby dissipating the compression force generated on the gas in the form of heat energy, etc., and the remaining gas will enter the inner anti-air cushion 54 through the two-way square tube 50, causing the inner anti-air cushion 54 to swell instantly, thereby playing a role in protecting the periphery of the battery assembly 2, and at the same time preventing the battery assembly 2 from being impacted, causing tiny cracks in the solid electrolyte or metal impurities to pierce the electrolyte layer, causing a short circuit inside the battery.

[0041] When the present invention is in use: first, the battery assembly 2 is placed inside the shell 1, and then the positive cover plate 47 is fixedly connected to the outer end face of the shell 1 by bolts. At this time, the cooling pipe 3 connected to the positive cover plate 47 will be placed at the bottom of the inner cavity of the shell 1, and then the negative cover plate 41 is fixedly connected to the other end face of the shell 1 by fasteners, and the cooling pipe 3 is inserted and supported at the same time, and then the double-way pipe 42 is put on one end of the cooling pipe 3, and the No. 1 return pipe 43 fixedly connected to the top of the double-way pipe 42 will be connected to the No. 2 return pipe 45 through the compensation sleeve 44, wherein the other end of the No. 2 return pipe 45 is connected to the peristaltic pump 46, and the other end of the peristaltic pump 46 is connected to the cooling pipe 3. Therefore, when the peristaltic pump 46 is started, the coolant inside the cooling tube 3 will be pushed slowly and periodically and flow, and then the coolant inside the cooling tube 3 will perform heat exchange processing on the heat emitted by the battery assembly 2. The coolant after the heat exchange will be discharged from the other end of the cooling tube 3 and enter the double-way tube 42. Then the coolant flowing out of the double-way tube 42 will re-enter the peristaltic pump 46 through the No. 1 return pipe 43, the compensation sleeve 44 and the No. 2 return pipe 45 in turn.

[0042] While the coolant flows in the cooling tube 3 and passes through the ring sleeve 481, the cooling tube 3 will periodically impact the force-bearing plate 489, and the impacted force-bearing plate 489 will move outward along the top of the cooling tube 3, and compress and stretch the leak-proof sheets 488 fixedly connected on both sides thereof, respectively, wherein both ends of the force-bearing plate 489 are fixedly connected with connecting rods 4807, and the other end of the connecting rod 4807 is fixedly connected with a double-headed rod 4808. Therefore, as the double-headed rod 4808 moves outward, the blocking plate 483 fixedly connected to the other end thereof will move forward along the inner rail 482, and the small radiator 484 originally blocked by the blocking plate 483 will be exposed, and at this moment the small radiator 484 will cool down the coolant after heat exchange. When the coolant is lost after a wave of impact force, the force-bearing plate 489 will return to its original position under the elastic force of the return spring 480, but at this time, part of the coolant will flow in the opposite direction during the return process of the force-bearing plate 489, and the cooling water flowing in the opposite direction will impact the one-way plate 4806. At this time, the one-way plate 4806 that is impacted will be deflected inward through the support 4805, causing the cooling water flowing in the opposite direction to pass through the one-way plate 4806 and enter the dredging pipe 4803. The other end of the dredging pipe 4803 is connected to the No. 1 double-pass plate 485. Therefore, part of the cooling water flowing in the opposite direction and the cooling water flowing forward will be divided into two paths, and finally meet in the No. 1 double-pass plate 485 until they enter the cooling pipe 3 together.

[0043] When the battery module is subjected to external impact and collision, the pressure block 53 will extend into the interior of the support frame 51 along the sliding rod 52, and the inner liner air cushion 501 is arranged inside the support frame 51, and the inner liner air cushion 501 is filled with gas, so the pressure block 53 will squeeze the inner liner air cushion 501. At this time, the part of the inner liner air cushion 501 that contacts the pressure block 53 will be compressed, and the lower part will expand, so the gas will surge downward and squeeze the force reducing plate 57 downward. At this time, the force reducing plate 57 will move downward along the vertical rail 55, and the friction protrusion 56 fixedly connected to the inside of the vertical rail 55 will increase the friction between the force reducing plate 57 and the vertical rail 55. Finally, the gas will enter the inner anti-air cushion 54 through the two-way square tube 50, and the inner anti-air cushion 54 will swell and realize the protection of the periphery of the battery assembly 2.
