[0002] The top cover and the shell of a square battery mostly adopt a split structure. The top cover and the shell are produced separately, and then the assembly between the top cover and the shell is completed through a pressing process. The pressing process usually first uses a shell fixing device to clamp and fix the battery shell, and then presses the top cover onto the opening end of the battery shell, and uses the interference fit between the top cover and the opening end of the shell to realize the combination between the top cover and the shell.

[0003] Currently, in the pressing process of the shell and the top cover, due to the inaccurate alignment between the top cover and the shell, the situation of poor pressing often occurs, resulting in the unusability of the pressed battery, which not only affects the production efficiency but also increases the production cost.

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0040] Embodiment 1:

[0041] This embodiment provides a positioning mechanism, including:

[0042] Substrate 1;

[0043] Two telescopic assemblies 2, and the two telescopic assemblies 2 are installed on the substrate 1 so as to be telescopic along the first direction X;

[0044] Pushing plate 3, the pushing plate 3 is installed on the substrate 1 so as to be movable along the second direction Y and abuts against the two telescopic assemblies 2;

[0045] Wherein, when the push plate 3 moves into the base body 1 along the second direction Y, it will push the two telescopic components 2 to extend out of the base body 1 along the first direction X.

[0046] In this technical solution, as Figure 1 , Figure 2 shown, the base body 1 is composed of an upper cover 11 and a base 12. The two telescopic components 2 are telescopically installed on the base 12 along the first direction X, and then the upper cover 11 is covered on the base 12 and fixed by bolts or screws to realize the connection and fixation between the telescopic component 2 and the base body 1. The upper cover 11 is provided with a guide groove 15, and the push plate 3 is movably arranged in the guide groove 15 along the second direction Y to ensure the stability of the movement of the push plate 3 in the second direction Y. When the push plate 3 moves into the base body 1 along the second direction Y, it will push the two telescopic components 2 to extend out of the base body 1 along the first direction X.

[0047] When performing the pressing operation of the battery case and the top cover, as Figure 3 shown, this positioning mechanism is installed on the shell fixing device for use. The shell fixing device includes a base frame 4, two clamping components 5 that can move closer to or away from each other along the second direction Y, and a driving member 6 for driving the clamping component 5 to move along the second direction Y. The base body 1 of the positioning mechanism is fixedly installed at the middle position of the base frame 4, the push plate 3 is installed on one of the clamping components 5, and the driving member 6 can be a cylinder. The cylinder drives the clamping component 5 to move along the second direction Y to clamp the large surface of the battery case. At the same time, the clamping component 5 will drive the positioning mechanism to work during the movement along the second direction Y.

[0048] The working principle of the positioning mechanism: When the clamping component 5 moves along the second direction Y, it drives the push plate 3 to move. The push plate 3 pushes the two telescopic components 2 to extend out of the base body 1 along the first direction X, so that the two telescopic components 2 respectively abut against the small surfaces of the two battery cases along the first direction X, and the other small surfaces of the two battery cases along the first direction X can abut against the base frame 4 of the clamping device, thereby realizing the positioning of the battery case in the first direction X, ensuring that the battery case can be stably clamped by the shell fixing device, and further ensuring that there will be no malfunction of poor pressing in the pressing of the battery case and the top cover.

[0049] It is worth mentioning that two positioning mechanisms can also be provided at both ends of the base frame 4 in the first direction X and controlled by the clamping component 5. When the clamping component 5 moves along the second direction Y, it drives the three positioning mechanisms on the base frame 4 to work, so that the two ends of the two battery cases along the first direction X are both abutted by the telescopic components 2 of the positioning mechanism, realizing the positioning of the battery case in the first direction X and ensuring the clamping stability.

[0050] To summarize, when the battery shell and the top cover are being press-fitted, by arranging the positioning mechanism on the shell fixing device, when the shell fixing device clamps and fixes the large surface of the battery shell, the telescopic component 2 of the positioning mechanism will extend out of the base 1 to abut against the small surface of the battery shell, thereby enhancing the stability of the battery shell fixation, avoiding the displacement of the battery shell during the press-fitting process, and effectively preventing the occurrence of poor press-fitting failures.

[0051] Embodiment 2:

[0052] This embodiment provides a positioning mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0053] Furthermore, the telescopic component 2 includes:

[0054] A push block 21, which is movably mounted on the base 1 along the first direction X and abuts against the push plate 3;

[0055] The resetting member 22 is installed in the base body 1 and is used to reset the push block 21 in the first direction X.

[0056] Furthermore, the reset member 22 is a spring, and two ends of the spring abut against the push block 21 and the base 1 respectively.

[0057] In this technical solution, if Figure 2 As shown, a positioning groove 16 is provided on the base 12 of the base 1, and an extension portion 211 of an integral structure is provided on the push block 21. When the push block 21 is installed on the base 12, the extension portion 211 is located in the positioning groove 16, and can move in the positioning groove 16 along the first direction X. The reset member 22 can be a spring, which is installed in the positioning groove 16, one end of the spring abuts against the inner wall of the positioning groove 16, and the other end abuts against the extension portion 211. When the push plate 3 moves to push the push block 21 to move along the first direction X, the extension portion 211 of the push block 21 squeezes the spring, so that the spring is compressed, and when the push plate 3 is reset, the spring recovers and pushes the extension portion 211 to move, thereby realizing the reset of the push block 21.

[0058] Embodiment 3:

[0059] This embodiment provides a positioning mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] Furthermore, the telescopic component 2 also includes:

[0061] Abutment member 23, the abutment member 23 is arranged on the push block 21;

[0062] The push plate 3 also includes:

[0063] The pushing end 31 is in a "V"-shaped structure;

[0065] In this technical solution, the abutting member 23 can be integrally connected to the pushing block 21 or detachably installed on the pushing block 21. During the movement of the push plate 3, the inclined end face of the pushing end 31 squeezes the abutting member 23, causing the abutting member 23 to slide in the first limiting groove 13, thereby driving the pushing block 21 to move, realizing the pushing block 21 to move along the first direction X to abut against the battery housing.

[0066] Furthermore, the abutting member 23 includes:

[0067] A first fastener 231, and the first fastener 231 is installed on the pushing block 21;

[0068] A first bearing 232, and the first bearing 232 is installed on the first fastener 231;

[0069] Among them, the first bearings 232 on the two abutting members 23 are respectively abutted against the two inclined end faces of the pushing end 31.

[0070] The first fastener 231 can be an internal hexagonal screw. The first bearing 232 is sleeved on the screw and is located between the screw head and the pushing block 21. Through this structural design, the abutting member 23 is integrally detachably installed on the pushing block 21, which helps with the installation and maintenance of the abutting member 23, reduces the maintenance cost, and improves the economic benefits; in addition, by providing the first bearing 232, during the movement of the push plate 3, the sliding friction between the abutting member 23 and the inclined end face is converted into rolling friction, reducing the wear of the whole abutting member 23 and the inclined end face, prolonging the service life, and having high practicability.

[0071] Embodiment 4:

[0072] This embodiment provides a positioning mechanism, which, in addition to including the technical solution of the above embodiment, also has the following technical features.

[0073] Furthermore, the base body 1 further includes:

[0075] Among them, a second limiting groove 32 is provided on the push plate 3, and the limiting member 14 is located in the second limiting groove 32.

[0076] In this technical solution, the push plate 3 is movably installed in the guiding groove 15 of the upper cover 11. The limiting member 14 penetrates through the guiding groove 15 and is located in the second limiting groove 32 of the push plate 3. Through this structural design, the movement of the push plate 3 can be restricted, preventing the push plate 3 from moving too far and causing the abutting member 23 to be damaged by extrusion. In addition, the limiting member 14 contacts the inner wall of the second limiting groove 32 of the push plate 3 along the first direction X, ensuring the movement stability of the push plate 3 and avoiding the deviation of the push plate 3 during movement.

[0077] Further, the limiting member 14 includes:

[0078] A second fastener 141, which is installed on the base body 1;

[0080] The second fastener 141 can also be an internal hexagonal screw. The second bearing 142 is sleeved on the screw and is located in the second limiting groove 32. Through this structural design, during the movement of the push plate 3, the sliding friction between the limiting member 14 and the inner wall of the second limiting groove 32 is converted into rolling friction, reducing the wear of the overall limiting member 14 and the push plate 3 and extending the service life.

[0081] Embodiment 5:

[0082] This embodiment provides a positioning mechanism, which, in addition to including the technical solution of the above embodiment, also has the following technical features.

[0083] Further, the push block 21 further includes:

[0084] A pressing block 24, which is detachably installed on the outer end of the push block 21 in the first direction X.

[0085] In this technical solution, the push block 21 abuts against the battery case through the pressing block 24. The pressing block 24 is made of rubber material and has a certain elasticity, which can play a certain buffering effect. During the process of the pressing block 24 abutting against the battery case, it can prevent the local deformation of the battery case and improve the protection effect on the battery case. In addition, the pressing block 24 can be installed on the push block 21 by setting fasteners, which helps with installation and replacement, reduces maintenance costs, and improves economic benefits.
