[0052] Figure 1 This is a front view of a press-fitting mechanism provided in one embodiment of the present application. Figure 2 A three-dimensional diagram of a portion of the structure of a press-fitting mechanism provided in one embodiment of the present application. Figure 3 A diagram of a portion of the structure of a press-fitting mechanism provided in one embodiment of the present application in a usage state. Figure 4 Another use state diagram of a part of the structure of the press-fitting mechanism provided in one embodiment of the present application. Figures 1 to 4The press-fitting mechanism provided in the embodiment of the present application includes a press-fitting component 1, a moving component 2, a press-fitting stroke adjustment component 3, a pressure-applying component 4, and a base 9.

[0053] The press-fitting component 1 is movably disposed on the base 9 along the press-fitting direction H of the press-fitting mechanism, that is, the press-fitting component 1 is disposed on the base 9 and can move along the press-fitting direction H relative to the base 9 .

[0054] The pressing component 1 is used to press the battery cell 100. Figure 1 Along the pressing direction H of the pressing mechanism, the pressing component 1 can move to abut against the surface of the battery cell 100, thereby pressing the battery cell 100; after the pressing is completed, the pressing component 1 can leave the surface of the battery cell 100. The pressing direction H can be the height direction of the pressing mechanism, and the height direction can also be the vertical direction.

[0055] The press-fit component 1 may specifically be a plate-shaped structure or a block-shaped structure.

[0056] refer to Figure 3 and Figure 4 The moving component 2 is movably disposed on the pressing component 1, that is, the moving component 2 is disposed on the pressing component 1 and can move relative to the pressing component 1 to achieve approaching or moving away from the pressure component 4 in the lateral direction W. The lateral direction W is perpendicular to the pressing direction H.

[0057] The press-fit stroke adjustment component 3 is detachably connected to the moving component 2 to realize replacement of different press-fit stroke adjustment components 3. Specifically, the press-fit stroke adjustment component 3 is abutted against the surface of the moving component 2, or the press-fit stroke adjustment component 3 is snap-fitted with the moving component 2, or the press-fit stroke adjustment component 3 is threadedly connected with the moving component 2.

[0058] The press-fitting stroke adjustment component 3 is detachably connected to the moving component 2, so that different press-fitting stroke adjustment components 3 can be replaced and the press-fitting stroke can be adjusted.

[0059] The pressure component 4 is disposed on the base 9. The pressure component 4 is used to press and install the stroke adjustment component 3.

[0060] The pressure-applying component 4 can be pressed against the surface of the press-fitting stroke adjustment component 3 to achieve press-fitting; after the press-fitting is completed, the pressure-applying component 4 can leave the surface of the battery cell 100 .

[0061] In the pressing direction H, the pressure-applying component 4 moves to abut against the surface of the pressing stroke adjusting component 3 and applies pressure to the pressing stroke adjusting component 3, so that the pressing stroke adjusting component 3 presses the moving component 2, and then the moving component 2 presses the pressing component 1, and then the pressing component 1 presses the battery cell 100 to achieve pressing.

[0062] According to the above content, it can be known that when it is necessary to press-fit battery cells 100 of different thicknesses, the moving component 2 drives the pressing stroke adjustment component 3 to move relative to the pressing component 1 so as to move away from the pressing component 4 in the horizontal direction W, and the pressing stroke adjustment component 3 is removed from the moving component 2, and the pressing stroke adjustment component 3 is replaced, so that the distance D between the pressing stroke adjustment component 3 and the pressing component 4 in the pressing direction H is changed, and the pressing stroke can be adjusted to change the movement distance of the pressing component 1 in the pressing direction H relative to the battery cell 100, so that battery cells of different thicknesses can be press-fitted.

[0063] Figure 5 A three-dimensional diagram of another partial structure of the press-fitting mechanism provided in one embodiment of the present application. Figure 6 This is a front view of another part of the structure of the press-fitting mechanism provided in one embodiment of the present application. Figure 5 and Figure 6 The moving assembly 2 may include a moving seat 21 and a pressure transmission head 22 .

[0064] refer to Figure 2 and Figure 5 The movable seat 21 is movably disposed on the press-fitting component 1 , that is, the movable seat 21 is disposed on the press-fitting component 1 and can move relative to the press-fitting component 1 to achieve a movement in the lateral direction W close to or away from the pressure assembly 4 .

[0065] The pressure transmission head 22 is movably disposed on the movable seat 21 in the press-fitting direction H of the press-fitting mechanism. That is, the pressure transmission head 22 is disposed on the movable seat 21 and can move along the press-fitting direction H relative to the movable seat 21 .

[0066] The pressure transmitting head 22 moves relative to the movable seat 21 along the pressing direction H, approaches the pressing component 1 and abuts against the pressing component 1 to transmit pressure to the pressing component 1 so that the pressing component 1 presses the battery cell 100 .

[0067] The press-fitting stroke adjusting component 3 is detachably connected to the pressure transmission head 22 to achieve replacement of the press-fitting stroke adjusting component 3 .

[0068] The pressure-applying assembly 4 applies pressure to the press-fitting stroke adjusting component 3, so that the press-fitting stroke adjusting component 3 presses the pressure transfer head 22. The pressure transfer head 22 moves relative to the moving seat 21 along the press-fitting direction H to press the press-fitting component 1, and transfers the pressure to the press-fitting component 1. This can prevent the pressure from being directly applied to the moving seat 21, protect the moving seat 21, and enable the moving seat 21 to move smoothly relative to the press-fitting component 1 for a long time.

[0069] In some other embodiments, the press-fitting stroke adjusting component 3 presses the pressure transmitting head 22 , the pressure transmitting head 22 presses the movable seat 21 , and then the movable seat 21 presses the press-fitting component 1 .

[0070] refer to Figure 5The moving component 2 may further include an elastic component 23 .

[0071] The elastic component 23 is connected to the pressure transmission head 22 and the movable seat 21 in the press-fitting direction H, so that the pressure transmission head 22 is elastically connected to the movable seat 21, so that the pressure transmission head 22 can be reset after the press-fitting is completed.

[0072] During press-fitting, the force borne by the movable seat 21 in the press-fitting direction H is mainly the elastic force exerted by the elastic component 23 .

[0073] The elastic component 23 may specifically be a spring or a bellows.

[0074] refer to Figure 5 The press-fitting stroke adjustment component 3 has a first matching portion 31 , and the pressure transmitting head 22 has a second matching portion 222 .

[0075] The first matching portion 31 is detachably connected to the second matching portion 222 , so that the press-fitting stroke adjustment component 3 is detachably connected to the pressure transmission head 22 .

[0076] Specifically, the first matching portion 31 and the second matching portion 222 are step portions, and the first matching portion 31 is abutted against the second matching portion 222; or, the first matching portion 31 and the second matching portion 222 are snap-fit ​​structures, and the first matching portion 31 and the second matching portion 222 are snap-fitted; or, the first matching portion 31 and the second matching portion 222 are matching portions with threads, and the first matching portion 31 and the second matching portion 222 are threadedly connected.

[0077] The above-mentioned press-fitting stroke adjustment component 3 also has a first locking portion (not shown in the figure), and the press-fitting stroke adjustment component 3 is locked to the pressure transmission head 22 through the first locking portion. Figure 5 The pressure transmission head 22 also has a second locking portion 223 , and the press-fitting stroke adjustment component 3 is locked to the pressure transmission head 22 via the second locking portion 223 .

[0078] The first locking portion and the second locking portion 223 may be pin holes, threaded holes, or fasteners.

[0079] refer to Figure 5 The moving seat 21 may include a moving plate 211 and a guide component 212 .

[0080] In the transverse direction W, the movable plate 211 is movably disposed on the press-fitting component 1 .

[0081] The guide member 212 is disposed on the moving plate 211 .

[0082] The pressure transmission head 22 is sleeved on the guide member 212 and can move along the press-fitting direction H relative to the movable plate 211 .

[0083] Under the guidance of the guide component 212 , the pressure transmission head 22 can move smoothly along the press-fitting direction H relative to the moving plate 211 .

[0084] refer to Figure 5 The pressure transmission head 22 may further include a mounting component 225 and a pressure transmission block 226 .

[0085] The mounting component 225 is sleeved on the guide component 212 so as to be movably arranged on the movable seat 21 in the press-fitting direction H, thereby achieving movement relative to the movable seat 21 along the press-fitting direction H under the guidance of the guide component 212 .

[0086] The pressure transmission block 226 is disposed on the mounting component 225 to move with the mounting component 225 , so as to be able to abut against the press-fit component 1 and transmit pressure to the press-fit component 1 .

[0087] In the pressing direction H, when the pressure applied by the pressure-applying assembly 4 to the pressing stroke adjustment component 3 is transmitted to the pressure transmission head 22, the pressure is mainly borne by the pressure transmission block 226 of the pressure transmission head 22, which can prevent the installation component 225 from being subjected to a large pressure and protect the installation component 225, thereby enabling the pressure transmission block 226 to smoothly move along the pressing direction H relative to the movable seat 21 for a long time.

[0088] refer to Figure 5 The pressure transmission head 22 may further include a connecting component 227 .

[0089] The pressure transmission block 226 is provided on the mounting member 225 via a connecting member 227 .

[0092] The slider 6 is arranged on the guide rail 5 .

[0093] The moving component 2 is arranged on the press-fitting component 1 through the guide rail 5 and the slider 6, so as to be movably arranged on the press-fitting component 1.

[0095] In some other embodiments, the press-fitting component 1 is provided with a slide groove, and the movable component 2 is movably arranged in the slide groove, so that the movable component 2 can also be movably arranged on the press-fitting component 1.

[0096] refer to Figure 1 The above-mentioned pressure-applying component 4 may include a movable head 41 and a press-fitting driving component 42 .

[0097] The movable head 41 is used to press the press-fitting stroke adjustment component 3. The movable head 41 can approach to the press-fitting stroke adjustment component 3 along the press-fitting direction H to abut against the press-fitting stroke adjustment component 3, and can move away from the press-fitting stroke adjustment component 3 along the press-fitting direction H.

[0098] The press-fitting driving component 42 is connected to the movable head 41 , so that the movable head 41 can move to abut against the press-fitting stroke adjusting component 3 and apply pressure to the press-fitting stroke adjusting component 3 .

[0099] The press-fitting driving component 42 may be specifically fixedly disposed on the base 9 .
