Specific embodiments

[0030] 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.

[0031] As Figures 1 to 8 shown, the present invention provides an aluminum electrode connection sealing device for an aluminum-air battery, including a sealing shell 1. A battery body 2 is arranged inside the sealing shell 1. An electrode body 3 is fixedly installed at the top of the battery body 2. A sealing plate 4 is sleeved on the surface of the top of the sealing shell 1. A wire outlet hole 14 is opened at the top of the sealing plate 4;

[0032] Fixing mechanism, which is arranged inside the sealing plate 4. The fixing mechanism includes a slide rail 5. The slide rail 5 is fixedly connected inside the sealing plate 4. A slider 6 is slidably sleeved on the surface of the slide rail 5. A connecting plate 7 is fixedly installed at the bottom of the slider 6. Jacks 12 are opened on both sides inside the sealing shell 1. An insertion block 8 located inside the jack 12 is fixedly installed on one side of the connecting plate 7. A threaded rod 9 located at the top of the slide rail 5 is rotatably connected inside the sealing plate 4. A threaded block 10 is threadedly sleeved on the surface of the threaded rod 9. The threaded block 10 is hinged to the slider 6 through a hinge rod 11. A rotating disk 13 is fixedly installed at the top of the threaded rod 9.

[0033] Adopt the above solution: The operator installs the battery body 2 inside the sealed housing 1. Then, the required conductive wires can be installed on the surface of the electrode body 3, and one end of the conductive wire is passed through the wire outlet hole 14. Then, the sealing plate 4 is sleeved on the surface of the top end of the sealed housing 1. Then, the conductive belt wire can be connected to external equipment to charge the equipment;

[0034] After the sealing plate 4 is sleeved on the surface of the sealed housing 1, the rotating disk 13 can be rotated. The rotating disk 13 will drive the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the threaded block 10, when the threaded rod 9 rotates, the threaded block 10 will move on the surface of the threaded rod 9. Since the threaded block 10 is hinged to the slider 6 through the hinge rod 11, when the threaded block 10 moves, it will drive the hinge rod 11 to rotate. The rotating hinge rod 11 will push the slider 6 to move towards each other on the surface of the slide rail 5. Then, the slider 6 will drive the connecting plate 7 and the plug 8 to move. Then, the plug 8 will enter the inside of the jack 12, so as to fix the sealing plate 4 on the top end of the sealed housing 1 through the jack 12, and then seal the battery body 2 and the electrode body 3. Finally, by rotating the rotating disk 13, the plug 8 enters the inside of the jack 12. Thus, without using fixing bolts, the battery body 2 and the electrode body 3 can be sealed, effectively preventing dust, moisture and other impurities from entering the battery, ensuring the normal operation of the battery and extending its service life.

[0035] As Figure 3 , Figure 4 , Figure 5 and Figure 8 shown, it further includes: a blocking mechanism, which is arranged at the top end of the threaded block 10. The blocking mechanism includes a rack 16, and the rack 16 is fixedly connected to the top end of the threaded block 10. An airbag 15 located on the surface of the wire outlet hole 14 is fixedly installed inside the sealing plate 4. One side of the surface of the airbag 15 is fixedly installed with an air inlet pipe 20. Inside the sealing plate 4, a first gear 17 meshing with the rack 16 is rotatably connected. One side of the first gear 17 is fixedly installed with a first lead screw 18 located inside the air inlet pipe 20. A blocking block 19 located inside the air inlet pipe 20 is threadedly connected to the surface of the first lead screw 18.

[0036] Adopting the above solution: Through the design of the plugging mechanism, when the threaded block 10 moves, it will drive the rack 16 to move. Since the rack 16 meshes with the first gear 17, the moving rack 16 will drive the first gear 17 to rotate. The first gear 17 will drive the first lead screw 18 to rotate. Since the first lead screw 18 is threadedly connected to the plugging block 19, when the first lead screw 18 rotates, the plugging block 19 will move on the surface of the first lead screw 18, and then the plugging block 19 will move into the inside of the air inlet pipe 20, thereby squeezing the air inside it. Then the squeezed air will enter the inside of the airbag 15. After the air enters the inside of the airbag 15, the airbag 15 will expand. Then the surface of the airbag 15 will contact the conducting wire inside the wire outlet hole 14. Thus, the airbag 15 can plug the wire outlet hole 14. Finally, through the threaded block 10 driving the rack 16, the airbag 15 expands, and thus the wire outlet hole 14 can be plugged, preventing dust from entering the sealing shell 1 along the wire outlet hole 14, thereby improving the sealing performance of the sealing shell 1.

[0037] As Figure 2 and Figure 6 shown, an insertion plate 21 is arranged inside the sealing plate 4. A sealing groove 23 is opened at the top end of the sealing shell 1. A sealing ring 22 located inside the sealing groove 23 is fixedly installed at the bottom end of the insertion plate 21. A limiting hole 24 is opened on the surface of the insertion plate 21.

[0038] Adopting the above solution: Through the design of the insertion plate 21, the sealing ring 22 and the sealing groove 23, when the sealing plate 4 is sleeved on the surface of the top end of the sealing shell 1, the sealing ring 22 will enter the inside of the sealing groove 23. Since the surface of the sealing ring 22 fits with the inner wall of the sealing groove 23, the sealing effect of the sealing shell 1 is increased.

[0039] As Figure 3 , Figure 6 and Figure 7 shown, it further includes: a limiting mechanism, which is arranged inside the sealing plate 4. The limiting mechanism includes a square shell 25. The square shell 25 is fixedly connected to the inside of the sealing plate 4. Both ends of the square shell 25 are rotatably connected to a second gear 26. A second lead screw 27 is slidably connected inside the interior formed by the square shell 25 and the second gear 26, and the second gear 26 is threadedly connected to the second lead screw 27. The number of the second lead screws 27 is two. A first limiting block 28 located inside the limiting hole 24 is fixedly installed on one side of the two second lead screws 27 facing each other. A rotating rod 29 is rotatably connected to the inside of the sealing plate 4. A third gear 30 meshing with the second gear 26 is fixedly sleeved on the surface of the rotating rod 29.

[0040] Adopting the above solution: Through the design of the limiting mechanism, when the sealing ring 22 has been used for a long time and needs to be replaced, the rotating rod 29 can be rotated. Then, the rotating rod 29 will drive the third gear 30 to rotate. Since the third gear 30 meshes with the second gear 26, the rotating third gear 30 will drive the second gear 26 to rotate. Since the second gear 26 is threadedly connected to the second lead screw 27, when the second gear 26 rotates, the second lead screw 27 will slide inside the second gear 26 and the second lead screw 27. Then, the second lead screw 27 will pull the first limiting block 28 away from the inside of the limiting hole 24. After the first limiting block 28 moves away from the inside of the limiting hole 24, the fixation of the insertion plate 21 and the sealing ring 22 will be cancelled. Then, the operator can replace the insertion plate 21 and the sealing ring 22;

[0041] Then, the unused insertion plate 21 and the sealing ring 22 can be inserted into the inside of the sealing plate 4. Then, the rotating rod 29 and the third gear 30 can be rotated in the reverse direction, so that the third gear 30 drives the second gear 26 to rotate in the reverse direction. Then, the second lead screw 27 will drive the first limiting block 28 to move towards the inside of the limiting hole 24. When the first limiting block 28 enters the inside of the limiting hole 24, the insertion plate 21 and the sealing ring 22 can be limited. Furthermore, the sealing shell 1 can continue to be sealed. Finally, by rotating the rotating rod 29, the first limiting block 28 is moved, which facilitates the operator to replace and install the insertion plate 21 and the sealing ring 22, thereby increasing the convenience of the device.

[0042] As Figure 2 、 Figure 3 and Figure 4 shown, an installation plate 31 is fixedly installed inside the sealing plate 4. A spring 32 is fixedly installed on one side of the installation plate 31, and one end of the spring 32 is fixedly connected to the insertion block 8. A limiting ring 33 located on the surface of the threaded rod 9 is rotatably connected inside the sealing plate 4, and the limiting ring 33 is fixedly connected to the threaded rod 9. The surface of the limiting ring 33 is in contact with the inner wall of the sealing plate 4.

[0043] Adopting the above solution: Through the design of the installation plate 31 and the spring 32, since one end of the spring 32 is fixedly connected to the insertion block 8, when the insertion block 8 moves, the spring 32 will be stretched. Then, when the insertion block 8 moves away from the inside of the insertion hole 12, due to the resilience of the spring 32, the spring 32 will pull the insertion block 8 back to its original position, which can reduce the load on the threaded rod 9 and increase the service life of the fixing mechanism. Through the design of the limiting ring 33, when the threaded rod 9 rotates, the limiting ring 33 will rotate accordingly. Since the surface of the limiting ring 33 is in contact with the inner wall of the sealing plate 4, during the rotation of the limiting ring 33, the threaded rod 9 can be limited and supported, thereby ensuring the stable rotation of the threaded rod 9.

[0044] As Figure 2 and Figure 7As shown in the figure, a limiting groove 34 is provided inside the square shell 25. The other end of the second lead screw 27 is fixedly installed with a second limiting block 35 located inside the limiting groove 34. The surface of the rotating disk 13 is provided with bumps, and the bumps are designed to be rough.

[0045] Adopting the above scheme: Through the design of the limiting groove 34 and the second limiting block 35, when the second lead screw 27 moves, it will drive the second limiting block 35 to slide inside the limiting groove 34. Then, the sliding second limiting block 35 can limit the second lead screw 27 to ensure that the second lead screw 27 can move stably. Through the design of the rotating disk 13, since the surface of the rotating disk 13 is provided with bumps and the bumps are designed to be rough, it can increase the friction with the fingers, thereby facilitating the operator to rotate the rotating disk 13.

[0046] As Figure 3 , Figure 4 and Figure 8 shown in the figure, a square groove is provided inside the sealing plate 4, and the rack 16 can slide inside the square groove. The number of the insertion blocks 8 is four, and every two insertion blocks 8 form a group. One end of the insertion block 8 far away from the center of the sealing plate 4 is designed with a chamfer.

[0047] Adopting the above scheme: Through the design of the sealing plate 4, when the threaded block 10 drives the rack 16 to move, the rack 16 will slide inside the square groove, so that the sealing plate 4 will not interfere with the movement of the rack 16. Through the design of the insertion blocks 8, since there are four insertion blocks 8, the four insertion blocks 8 can enter the inside of the jack 12 at the same time, thereby increasing its fixing effect. And one end of the insertion block 8 far away from the center of the sealing plate 4 is designed with a chamfer, which is convenient for the insertion block 8 to enter the inside of the jack 12.

[0048] The working principle and usage process of the present invention:

[0049] First, the operator installs the battery body 2 inside the sealing shell 1, then the conductive wire can be installed on the surface of the electrode body 3, and the conductive wire is passed through the wire outlet hole 14. Then, the sealing plate 4 is sleeved on the surface of the top end of the sealing shell 1. When the sealing plate 4 is sleeved on the surface of the sealing shell 1, the sealing ring 22 will enter the inside of the sealing groove 23, thereby improving its sealing effect. Then, the conductive belt line can be connected to the device to be charged, so as to charge the device.

[0050] After the sealing plate 4 is sleeved on the surface of the sealing shell 1, the rotating disc 13 and the threaded rod 9 can be rotated. Then, the threaded block 10 will move on the surface of the threaded rod 9. When the threaded block 10 moves, it will drive the hinge rod 11 to rotate. The hinge rod 11 will push the slider 6 to move towards each other on the surface of the slide rail 5. Then, the slider 6 will drive the connecting plate 7 and the insertion block 8 to move into the jack 12. Then, the insertion block 8 will enter the inside of the jack 12, thereby fixing the sealing plate 4 on the surface of the top end of the sealing shell 1, and the sealing plate 4 can seal the battery body 2 and the electrode body 3;

[0051] At the same time, when the threaded block 10 moves, it will drive the rack 16 to move. The rack 16 will drive the first gear 17 and the first lead screw 18 to rotate. The blocking block 19 will move on the surface of the rotating first lead screw 18 and squeeze the air inside the air inlet pipe 20. Then, the squeezed air will enter the inside of the airbag 15. After the air enters the inside of the airbag 15, the airbag 15 will expand. Then, the surface of the airbag 15 will contact the conducting wire inside the wire outlet hole 14, and then the airbag 15 can block the wire outlet hole 14;

[0052] When the sealing ring 22 needs to be replaced after long-term use, the rotating rod 29 and the third gear 30 can be rotated. The third gear 30 will drive the second gear 26 to rotate. The second lead screw 27 will slide inside the second gear 26 and the second lead screw 27. Then, the second lead screw 27 will pull the first limiting block 28 away from the inside of the limiting hole 24, and then the fixation of the insertion plate 21 and the sealing ring 22 will be cancelled. Then, the operator can replace the insertion plate 21 and the sealing ring 22, and finally complete the operation process.
