Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to a lithium battery upper cover structure which is convenient for connecting electricity. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. The lithium battery cover is a part of the lithium battery structure. Its main function is to seal the lithium battery, prevent the leakage of internal battery substances and the entry of external impurities, and ensure the safety and stability of the battery. The lithium battery cover is generally made of stainless steel, aluminum alloy and other materials, which has good corrosion resistance and sealing performance. In the production process of lithium batteries, the cover needs to be strictly matched and welded with other parts of the battery to ensure the safety and reliability of the battery.

[0003] As disclosed in Chinese patent: Lithium battery upper cover plate structure, application number: CN202022810277.4, including a cover plate and a pole, the cover plate is penetrated by a stepped hole at the upper end for the pole to pass through, the stepped hole has a fine hole located at the top and a coarse hole located at the bottom, the middle part of the pole is arched upward to form a protrusion, the pole is located in the coarse hole, and the protrusion of the pole is located in the fine hole; a clamping portion extends downward from the edge of the coarse hole on the lower surface of the cover plate, and the bottom end of the clamping portion is bent inward to have a bent portion. The utility model adopts a design that the middle part of the pole is arched upward, so that a depression is formed below the middle part of the pole, so as to leave more space for the interior of the lithium battery, which can increase the battery capacity, and the cover plate adopts a bent portion to directly fix the pole in the stepped hole, thereby further reducing the occupied space of the lithium battery upper cover plate structure and increasing the battery capacity. It has the advantages of compact and simple structure, can reduce costs, and improve market competitiveness.

[0004] However, in the above technical solution, the lithium battery needs to be connected to the power supply during use. At present, the connection method mostly adopts the threaded extrusion connection method. When performing the threaded extrusion connection, the staff needs to use special tools to connect the power. Therefore, after moving the lithium battery to the designated position, the staff still needs to find or purchase special tools for connection operations, which is inconvenient for the staff to connect the power.

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, a lithium battery cover structure for convenient power connection includes a base 1, a handle mounting block 2 is provided on the base 1, two slots 3 are provided on the handle mounting block 2, a handle 4 is provided in the slot 3, two power connection posts 5 are provided on one side of the base 1, a first threaded hole 6 is provided on the power connection post 5, a flat-head threaded power connection post 7 is provided in the first threaded hole 6, a plurality of second threaded holes 8 are provided on the base 1, and flat-head bolts 9 are provided in the second threaded holes 8.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the handle 4 includes a first handle base 401, a first threaded column 402 is provided on the handle base 401, a rotating ring 403 is provided on the first threaded column 402, a threaded groove 404 is provided on the rotating ring 403, and a rotating friction pattern 405 is provided on the outer wall of the rotating ring 403;

[0025] A second threaded column 406 is arranged in the threaded groove 404, and a straight head 407 is fixedly arranged on the outer wall of the second threaded column 406 on one side close to the first threaded column 402, and a second grip base 408 is arranged on the outer wall of the second threaded column 406 at one end away from the straight head 407. When it is necessary to connect the power, the rotating ring 403 is first rotated, and the rotating friction pattern 405 is used to facilitate the staff to rotate the rotating ring 403. The rotating ring 403 moves in the direction away from the second grip base 408 through the threaded groove 404, so that the rotating ring 403 and the second threaded column 406 are gradually separated. When the rotating ring 403 and the second threaded column 406 are completely separated, the second grip base 408 can be removed from one end. Take it out from the slot 3 to disengage the second handle base 408 from the handle mounting block 2, then insert the flat head 407 into the flat threaded power post 7, and then rotate the second handle base 408. The second handle base 408 drives the flat threaded power post 7 to rotate through the flat head 407, and the power connection plate is fixedly connected to the power connection post 5 through the flat threaded power post 7. Then, insert one end of the second handle base 408 back into the slot 3, and rotate the rotating ring 403 so that the rotating ring 403 and the second threaded post 406 are re-engaged with each other, so that the second handle base 408 is re-fixedly connected to the handle base 401 through the rotating ring 403, which is convenient for the staff to move the lithium battery through the handle 4.

[0026] The working principle of the lithium battery cover structure that is convenient for connecting to electricity:

[0027] When in use, first connect the base 1 to the lithium battery through the second threaded hole 8 and the flat bolt 9. Then, when it is necessary to connect electricity, first rotate the rotating ring 403, and the rotating ring 403 moves in the direction away from the second grip base 408 through the threaded groove 404, so that the rotating ring 403 and the second threaded column 406 are gradually separated. When the rotating ring 403 and the second threaded column 406 are completely separated, one end of the second grip base 408 can be taken out of the slot 3, and then the power connection piece is placed on the surface of the power connection post 5, and then the flat head 407 is inserted into the flat threaded power connection post 7, and then the second grip base 408 is rotated. The second grip base 408 drives the flat threaded power connection post 7 to rotate through the flat head 407, and the flat thread connection The electric post 7 moves toward the power connection post 5 through the first threaded hole 6, so that the power connection plate and the power connection post 5 are squeezed and fixedly connected using the straight-threaded power connection post 7. The power connection plate and the power connection post 5 can be quickly connected without finding or purchasing special tools for connection operations, thereby facilitating the staff to connect the power. After the power connection is completed, one end of the second handle base 408 is reinserted into the slot 3, and the rotating ring 403 is rotated so that the rotating ring 403 and the second threaded post 406 are re-engaged with each other, thereby re-fixing the second handle base 408 and the handle base 401 through the rotating ring 403, and then the staff can move the lithium battery through the handle 4, which is convenient for the staff to move the lithium battery.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
