[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of 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.

[0019] As Figures 1 to 4 shown, the present invention provides a heat dissipation and explosion-proof outer shell for a storage battery, including an outer shell 1. A plurality of first fan blades 21 are arranged in the outer shell 1 at equal circumferential intervals. A second fan blade 22 is rotatably connected to one side of the first fan blade 21, and a detector 3 is installed on the lower surface of the second fan blade 22.

[0020] Among them, the number of the first fan blades 21 and the second fan blades 22 is equal, and both are four.

[0021] Among them, the detector 3 is used to detect whether the battery bulges, and the detection method of the detector 3 is completed by observing the appearance of the battery.

[0022] A heat dissipation mechanism for driving the first fan blade 21 and the second fan blade 22 to rotate to complete the heat dissipation work is arranged in the outer shell 1; A detection mechanism for driving the first fan blade 21, the second fan blade 22 and the detector 3 to move horizontally to expand the detection range of the detector 3 is arranged in the outer shell 1; A deformation mechanism is arranged on the first fan blade 21 and the second fan blade 22; By arranging the heat dissipation mechanism, the first fan blade 21 and the second fan blade 22 can be driven to rotate to dissipate heat from the battery; By arranging the detection mechanism, the first fan blade 21 and the second fan blade 22 can be driven to move horizontally, and the second fan blade 22 can drive the detector 3 installed on its lower surface to move accordingly, so as to expand the detection range of the detector 3; In the initial state, the first blade 21 and the second blade 22 are in a planar state, and the detector 3 on the lower surface of the second blade 22 can observe and detect the upper surface of the battery; By setting the deformation mechanism, after the second blade 22 horizontally moves to the outside of the battery, the second blade 22 can be driven to rotate to a state perpendicular to the first blade 21, so that the detector 3 on the second blade 22 can detect the side wall of the battery; Moreover, the four detectors 3 respectively correspond to the four side walls of the battery.

[0023] Such as Figures 1 - 5 As shown, the heat dissipation mechanism includes a first U-shaped bearing seat 41 fixed to the top surface of the inner wall of the housing 1. A first gear 42 is rotatably connected to the first U-shaped bearing seat 41. A hollow electric telescopic rod 43 rotatably connected to the first U-shaped bearing seat 41 penetrates through the first U-shaped bearing seat 41. A second gear 44 and a third gear 45 fixedly connected to the hollow electric telescopic rod 43 are sleeved on the hollow electric telescopic rod 43, and the second gear 44 meshes with the first gear 42.

[0024] The first gear 42 is driven by an external motor; Such as Figure 5 As shown, the hollow electric telescopic rod 43 includes an upper rod body rotatably connected to the first U-shaped bearing seat 41 and a lower rod body located below the first U-shaped bearing seat 41 and telescopically inserted with the upper rod body. The second gear 44 is sleeved on the upper rod body of the hollow electric telescopic rod 43, and the third gear 45 is sleeved on the lower rod body of the hollow electric telescopic rod 43.

[0025] Adopting the above scheme enables the first gear 42 to drive the hollow electric telescopic rod 43 and the third gear 45 to rotate through the second gear 44, and the third gear 45 can move up and down following the lower rod body of the hollow electric telescopic rod 43 and rotate at different positions.

[0026] Such as Figure 2 And Figure 5 As shown, a second U-shaped bearing seat 46 is fixedly connected to the top surface of the inner wall of the housing 1. An annular frame 47 rotatably connected to the second U-shaped bearing seat 46 penetrates through the second U-shaped bearing seat 46. An internal gear ring 48 meshing with the third gear 45 is fixedly connected to the inner wall of the annular frame 47.

[0027] Such as Figure 2 And Figure 3 As shown, a circular plate 49 is fixedly connected to the lower end of the annular frame 47. Four limiting grooves 410 are formed in the circular plate 49 at equal circumferential intervals. A sliding rod 411 slidably connected to each limiting groove 410 penetrates through each limiting groove 410, and the four first blades 21 are respectively fixed to the lower ends of the four sliding rods 411.

[0028] Such as Figure 1 And Figure 5As shown, the detection mechanism includes a worm 51 rotatably connected to the top surface of the inner wall of the housing 1, and a fourth gear 52 located above the worm 51 and fixedly connected coaxially with the worm 51. The worm 51 is located within the annular frame 47, and an internal gear ring two 53 meshing with the fourth gear 52 is fixedly connected to the inner wall of the lower rod body of the hollow electric telescopic rod 43.

[0029] With the above solution, while the hollow electric telescopic rod 43 drives the third gear 45 and the internal gear ring two 53 to rotate, the internal gear ring two 53 can drive the worm 51 to rotate accordingly through the fourth gear 52; Since the third gear 45 and the internal gear ring two 53 can move up and down following the lower rod body of the hollow electric telescopic rod 43, there are two cases: First, as Figure 5 shown, the third gear 45 and the internal gear ring one 48 are in a meshing state with each other, and the internal gear ring two 53 and the fourth gear 52 are also in a meshing state with each other. Then the third gear 45 can drive the annular frame 47 to rotate through the internal gear ring one 48, and the annular frame 47 can drive the circular plate 49, the sliding rod 411 and the first fan blade 21 to rotate, while the internal gear ring two 53 can drive the worm 51 to rotate through the fourth gear 52, so that the worm 51 and the first fan blade 21 are both in a rotating state; Second, when the third gear 45 disengages from the internal gear ring one 48 and the internal gear ring two 53 still meshes with the fourth gear 52, then only the worm 51 can rotate following the hollow electric telescopic rod 43.

[0030] As Figure 2 shown, four vertical plates 54 are vertically fixed to the upper surface of the circular plate 49. A worm gear 55 meshing with the worm 51 is rotatably connected to the vertical plates 54, and an activity groove 56 adapted to the worm gear 55 is provided on the surface of the annular frame 47.

[0031] By providing the activity groove 56, it is convenient for the worm gear 55 to enter the annular frame 47 to mesh with the worm 51.

[0032] As Figure 2 shown, a threaded rod 57 coaxially fixed with the worm gear 55 is rotatably connected to each vertical plate 54. An internal threaded sleeve 58 threadedly connected to the threaded rod 57 is sleeved on the threaded rod 57, and the sliding rod 411 is fixedly connected to the lower surface of the internal threaded sleeve 58.

[0033] With the above solution, when the worm 51 rotates alone, it can drive the four worm gears 55 meshing with it to rotate accordingly. The worm gears 55 can drive the threaded rods 57 coaxially fixed with them to rotate, and the threaded rods 57 can drive the internal threaded sleeves 58, the sliding rods 411, the first fan blade 21 and the second fan blade 22 to move horizontally. The second fan blade 22 drives the detector 3 to move horizontally accordingly, expanding the detection range of the detector 3.

[0034] AsFigure 4 As shown in the figure, the deformation mechanism includes a swing rod 61 rotatably connected to the first fan blade 21 and coaxially fixed to the second fan blade 22. A first positioning block 62 is rotatably connected to the swing rod 61, and a second positioning block 63 is rotatably connected to the side wall of the first fan blade 21. A spring 64 is fixedly connected between the first positioning block 62 and the second positioning block 63.

[0035] As Figure 4 、 Figure 6 and Figure 7 shown in the figure, two symmetrically distributed baffles 65 are fixedly connected to the side wall of the first fan blade 21. A roller 66 is rotatably connected to the side of each second fan blade 22 away from the first fan blade 21. A guide plate 67 corresponding to the roller 66 is fixedly connected to the inner side wall of the housing 1.

[0036] Among them, the baffle 65 can limit the rotation range of the swing rod 61, allowing the swing rod 61 and the second fan blade 22 to only rotate 90 degrees, so that the second fan blade 22 and the first fan blade 21 are either in a flat state or in a vertical state; By setting the roller 66, the friction between the second fan blade 22 and the guide plate 67 can be reduced; When the first fan blade 21 and the second fan blade 22 move toward the side close to the guide plate 67, the roller 66 on the second fan blade 22 will gradually abut against the inclined end of the guide plate 67. Restricted by the inclined end of the guide plate 67, the second fan blade 22 will rotate downward. The second fan blade 22 can drive the swing rod 61 to rotate 90 degrees accordingly, so that the detector 3 installed on the second fan blade 22 can detect the side wall of the battery. When the second fan blade 22 and the swing rod 61 rotate downward, but before they rotate to 90 degrees, the spring 64 can already generate a pulling force on the swing rod 61 and the second fan blade 22, pulling the swing rod 61 and the second fan blade 22 to complete a 90-degree rotation. As Figure 7 shown in the figure, the end of the guide plate 67 away from the housing 1 is inclined. A battery body 7 is installed in the housing 1. Four vertical rods 68 are vertically fixed on the upper surface of the battery body 7. The four vertical rods 68 correspond to the four guide plates 67 one by one.

[0037] When the second fan blade 22 and the first fan blade 21 are in a vertical state and move toward the side close to the vertical rod 68, the vertical rod 68 will restrict the second fan blade 22, causing the second fan blade 22 to rotate upward 90 degrees to become a horizontal state.

[0038] As Figure 8 and Figure 1As shown, each first fan blade 21 has a hollow structure, and a circular hole 81 communicating with its interior is provided on one side close to the second fan blade 22. A needle body 82 adapted to the circular hole 81 is fixedly connected to the side wall of the outer shell 1. An airbag is placed in the cavity of the first fan blade 21, and fire extinguishing powder is placed in the airbag. A plurality of discharge holes are provided on the lower surface of the first fan blade 21.

[0039] Among them, the airbag, the fire extinguishing powder and the discharge holes are not shown in the figure; When the second fan blade 22 and the first fan blade 21 are in a vertical state, the circular hole 81 on the first fan blade 21 will be exposed. Drive the first fan blade 21 to move towards the side close to the needle body 82, so that the needle body 82 extends into the first fan blade 21 through the circular hole 81, puncturing the airbag inside the first fan blade 21, and then the dry powder can be sprinkled out through the discharge holes, achieving an effect of cooling and extinguishing the fire; Moreover, the first fan blade 21 can rotate to sprinkle out the dry powder.

[0040] The working principle of the present invention: During use, the third gear 45 and the second internal gear ring 53 can move up and down following the lower rod body of the hollow electric telescopic rod 43; As Figure 2 and Figure 5 shown, the third gear 45 and the first internal gear ring 48 are in a meshing state, and the second internal gear ring 53 and the fourth gear 52 are also in a meshing state. Then the third gear 45 can drive the annular frame 47 to rotate through the first internal gear ring 48. The annular frame 47 can drive the circular plate 49, the sliding rod 411, the first fan blade 21, the second fan blade 22, the vertical plate 54 and the worm gear 55 to rotate. And the second internal gear ring 53 can drive the worm 51 to rotate through the fourth gear 52, so that the worm 51 and the worm gear 55 are both in a rotating state. At this time, the worm gear 55 and the worm 51 are relatively stationary; And the first fan blade 21 and the second fan blade 22 complete the heat dissipation work of the battery during rotation; When it is necessary to expand the detection range of the detector 3, separate the third gear 45 from the first internal gear ring 48. The second internal gear ring 53 is still meshed with the fourth gear 52. Then at this time, only the worm 51 can rotate following the hollow electric telescopic rod 43, and the first internal gear ring 48, the annular frame 47 and the circular plate 49 cannot rotate; When the worm 51 rotates alone, it can drive the four worm gears 55 meshed with it to rotate accordingly. The worm gear 55 can drive the threaded rod 57 fixedly connected to its coaxial to rotate. The threaded rod 57 can drive the internal threaded sleeve 58, the sliding rod 411, the first fan blade 21 and the second fan blade 22 to move horizontally. The second fan blade 22 drives the detector 3 to move horizontally accordingly, expanding the detection range of the detector 3; When the first blade 21 and the second blade 22 move towards the side close to the guide plate 67, the roller 66 on the second blade 22 will gradually abut against the inclined end of the guide plate 67. Restricted by the inclined end of the guide plate 67, the second blade 22 will rotate downward. The second blade 22 can drive the swing rod 61 to rotate ninety degrees accordingly, so that the detector 3 installed on the second blade 22 can detect the side wall of the battery. When the second blade 22 and the swing rod 61 rotate downward, but before they rotate to ninety degrees, the spring 64 can already generate a pulling force on the swing rod 61 and the second blade 22, pulling the swing rod 61 and the second blade 22 to complete a ninety-degree rotation. When the second blade 22 and the first blade 21 are in a vertical state and move towards the side close to the vertical rod 68, the vertical rod 68 will restrict the second blade 22, causing the second blade 22 to rotate upward ninety degrees to become horizontal. When the second blade 22 and the first blade 21 are in a vertical state, the round hole 81 on the second blade 22 will be exposed. Drive the first blade 21 to move towards the side close to the needle body 82, so that the needle body 82 extends into the first blade 21 through the round hole 81, puncturing the airbag inside the first blade 21, and then the dry powder can be sprinkled out through the discharge hole, achieving an effect of cooling and extinguishing the fire.
