[0002] As we all know, the use of a carrier is indispensable in the pack assembly process of soft-pack batteries. The carrier is used to position and clamp the soft-pack batteries, thus facilitating the subsequent assembly operations of the soft-pack batteries.

[0003] Among them, in the existing carrier, it can only flexibly press on one side of the soft-pack battery cell that is separated in the width direction, and then the soft-pack battery cell is positioned on the other side that is separated in the width direction, thereby achieving the purpose of positioning and clamping the soft-pack battery cell in the width direction; and the soft-pack battery cell is separated on one side in the thickness (or height) direction by the bearing structure in the carrier, and the soft-pack battery cell is pressed by the upper cover in the carrier on the other side that is separated in the thickness (or height) direction.

[0004] However, the existing carrier can only provide a single reference edge for the soft-pack battery cell, so it has poor compatibility and is not conducive to improving production efficiency.

[0005] Therefore, there is an urgent need for a multi-directional top-pressing positioning vehicle for a cell or battery to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-directional top-pressing positioning carrier for a cell or battery, so that the battery or cell has a double reference edge function, thereby having good compatibility and facilitating improved production efficiency; and it can also be compatible with positioning and clamping batteries or cells with large tolerances.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a multi-directional top-pressure positioning carrier for battery cells or batteries, comprising a carrier body, a top-pressure assembly, a cover body, a push body and a push-pushing reset member. The cover body rotates and opens and closes relative to the carrier body around a rotation centerline, and the cover body is provided with a main top surface, and the rotation centerline is arranged along a first direction.

Therefore, the multi-directional top-pressing positioning carrier for the battery cell or battery of the utility model has good compatibility, which is conducive to improving production efficiency. It can also be compatible with the positioning and clamping of batteries or battery cells with large tolerances.

[0035] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0036] See also Figure 1 、 Figure 2 and Figure 6 As an example, the multi-directional pressing positioning carrier 100 for a battery cell or battery of the present invention includes a carrier body 10, a pressing assembly 20, a cover 30, a pushing body 40, and a pushing and resetting member 50. The cover 30 rotates about a rotation centerline C1 relative to the carrier body 10 to open and close, and has a main top surface 31.

[0037] The rotation center line C1 is arranged along the first direction (as indicated by the double arrow A), for example, Figures 1 to 6 As an example, the first direction is the front-rear direction of the carrier body 10; obviously, according to actual needs, the first direction can also be the left-right direction of the carrier body 10, so it is not necessary to use Figures 1 to 5 Limits shown.

[0038] At the same time, the carrier body 10 is provided with a supporting structure 11 for supporting the battery cell 200 and a positioning structure 12 for positioning the battery cell 200 supported by the supporting structure 11 in a second direction (as indicated by the double arrow B). Figures 1 to 6 As an example, the second direction is the left-right direction of the carrier body 10 , and the positioning structure 12 positions the battery cell 200 from the left side of the carrier body 10 .

[0039] The top-pressing assembly 20 includes a first reset member 21, a top-receiving body 22, a first top-pressing body 23, a second top-pressing body 26 and a second reset member 27. The top-receiving body 22 is linked with the main top surface 31 to meet the need of the main top surface 31 to link the top-receiving body 22 to move. The first top-pressing body 23 is arranged relative to the positioning structure 12 in the second direction to meet the need of the first top-pressing body 23 and the positioning structure 12 to clamp the battery cell 200 carried by the supporting structure 11 in the second direction; and the positioning structure 12 is located between the top-receiving body 22 and the first top-pressing body 23, so that the top-receiving body 22 and the first top-pressing body 23 are arranged on opposite sides with the positioning structure 12 as the center; the top-receiving body 22 is also fixed to the first top-pressing body 23 by means of a connecting rod 24 extending along the second direction. Optionally, Figure 8In the embodiment, one end of the connecting rod 24 is fixedly connected to the support body 22, while the other end is fixedly connected to the first pressure body 23, so that the support body 22 and the first pressure body 23 are fixed together through the connecting rod 24, thereby meeting the need for the three to slide together relative to the carrier body 10. In addition, the first reset member 21 is provided between the support body 22 and the first pressure body 23. The first reset member 21 enables the support body 22 to drive the first pressure body 23 to slide closer to the positioning structure 12 through the connecting rod 24, so that the first pressure body 23 has a flexible buffering effect on the pressure of the battery cell 200. On the one hand, it protects the battery cell 200, and on the other hand, it can accommodate the tolerance of the battery cell 200 in the second direction. In addition, the second pressure body 26 is assembled to the cover body 30 in a buffering and telescopic manner with the help of the second reset member 27, so that the second pressure body 26 has a flexible buffering effect on the pressure of the battery cell 200. The pushing body 40 slides along a first direction (indicated by the double arrow A) on the carrier body 10 and corresponds to the battery cell 200 supported by the supporting structure 11, thereby enabling the pushing body 40 to push and position the battery cell 200. The pushing body 40 is also interlocked with the first pressing body 23 to ensure interlocking movement between the pushing body 40 and the first pressing body 23. A pushing and restoring member 50 is disposed between the pushing body 40 and the carrier body 10, maintaining contact between the pushing body 40 and the first pressing body 23 to ensure the sensitivity of their interlocking movement.

[0040] Therefore, during the closing process of the cover 30, the main top surface 31, in cooperation with the first reset member 21, drives the first pressing member 22 to slide close to the positioning structure 12. At the same time, the first pressing member 23, in cooperation with the push reset member 50, drives the pushing member 40 to slide close to the battery cell 200 carried by the support structure 11. The sliding first pressing member 23 presses on the battery cell 200 carried by the support structure 11, and the sliding pushing member 40 pushes the battery cell 200 on the support structure 11. The state is shown in FIG. Figure 11 and in the process of closing the cover 30, the second pressing body 26 also presses on the battery cell 200 carried by the supporting structure 11 from the direction opposite to the supporting structure 11, so as to realize the battery cell 200 in the third direction (see Figure 8 The purpose of clamping is to clamp the

[0041] Therefore, after the cover 30 is closed, the battery cell 200 is clamped in the second direction and the third direction, and is also pushed and positioned in the first direction, so that the battery cell 200 has a double reference edge effect. It should be noted that due to the design of the first reset member 21 and the second reset member 27, the first pressing body 23 and the second pressing body 26 have the advantage of controllable pressure when pressing the battery cell 200; in addition, with the cooperation of the first reset member 21, the pressing body 22 can always maintain contact with the main top surface 31 during the opening and closing process of the cover 30, and under the action of the pushing reset member 50, the pushing body 40 has a flexible effect on the positioning of the battery cell 200. It is worth noting that the second pressing body 26 and the second reset member 27 can be deleted according to actual needs, so it is not limited to the figure shown. More specifically, as follows:

[0042] like Figures 1 to 5 and Figures 10 and 11 As shown, as an example, the pushing body 40 is provided with an inclined linkage surface 41 arranged obliquely relative to the first direction. Optionally, the inclined linkage surface 41 is an inclined plane, but not limited thereto. Correspondingly, the first pressing body 23 is provided with a linkage protrusion 23 that cooperates with the inclined linkage surface 41. By means of the cooperation between the linkage protrusion 23 and the inclined linkage surface 41, the linkage cooperation structure between the pushing body 40 and the first pressing body 23 is simplified. Specifically, Figures 1 to 5 and Figures 10 and 11 In the figure, as an example, the linkage protrusion 231 is a bearing, and the center line of the linkage protrusion 231 extends along the third direction (as indicated by the double arrow C); this design makes the linkage between the first pressing body 23 and the pushing body 40 smoother; obviously, according to actual needs, the linkage protrusion 231 can also be a column or a wheel, so it is not limited to the figure shown. It is additionally noted that Figures 1 to 5 In the figure, the third direction is the up-down direction of the carrier body 10. Correspondingly, the third direction is perpendicular to the first direction and the second direction, respectively, and they together constitute the X-axis direction, Y-axis direction and Z-axis direction in the three-dimensional coordinate system. In addition, according to actual needs, the positions of the inclined linkage surface 41 and the linkage protrusion 23 can be swapped, that is, the inclined linkage surface 41 is provided by the first pressing body 23, and the linkage protrusion 23 is provided by the pushing body 40.

[0043] like Figure 8 As shown in FIG. 1 , as an example, the top receiving body 22 extends along the first direction, and a rolling bearing 25 is provided on the top receiving body 22 to cooperate with the main top surface 31. With the help of the rolling bearing 25, the linkage between the main top surface 31 and the top receiving body 22 is smoother and more reliable, avoiding defects such as jamming. Figure 8 As an example, the connecting rod 24 is slidably inserted into the carrier body 10 along the second direction, so as to improve the smoothness and reliability of the sliding of the top body 22 and the first top pressure body 23 through the sliding cooperation between the connecting rod 24 and the carrier body 10; Figure 8 In the embodiment, the connecting rod 24 is located below the supporting structure 11, so that the arrangement of the connecting rod 24 on the carrier body 10 is more reasonable. In addition, the first reset member 21 is a spring that is sleeved on the connecting rod 24. A stop boss 241 is provided at the position where the connecting rod 24 is connected to the support body 22. The spring is also elastically abutted between the carrier body 10 and the stop boss 241. Figure 8 As shown, the main top surface 31 is effectively improved in cooperation with the first reset member 21, and the linkage of the top body 22 drives the first top pressure body 23 to slide close to the positioning structure 12. Obviously, according to actual needs, the first reset member 21 can also be composed of two magnets arranged to repel each other. Figure 8 Limits shown.

[0044] like Figure 15 As shown, as an example, the main top surface 31 is a cylinder, that is, the cylinder number is also 31, and the straight main line C2 of the cylinder 31 is parallel to the rotation center line C1; the directrix 311 of the cylinder 31 includes an arc 3111, a line segment 3112 and a line segment 3112', and the line segment 3112 and the line segment 3112' are arranged tangent to the arc 3111, and the arc 3111 is connected between the line segment 3112 and the line segment 3112'; this design allows the rolling bearing 25 to abut against the part of the cylinder 31 where the line segment 3112 is located when the cover body 30 is in the open state, providing a hovering effect for the cover body 30 in the open state; in addition, with the help of the part of the cylinder 31 where the line segment 3112' is located, when the cover body 30 is in the closed state, the cylinder 31 drives the first pressing body 23 to be in the position closest to the positioning structure 12. In addition, the cylindrical surface 31 where the arc 3111 is located plays a smooth transition role, ensuring the smoothness of the cylindrical surface 31 linked to the rolling bearing 25. Obviously, according to actual needs, the cylindrical surface can also be other, for example, Figure 16 In the figure, the cylindrical surface 31' comprises a line segment 3112 and an arc 3111 arranged tangentially, and the arc diameter of the arc 3111 is greater than Figure 15 The arc diameter of the arc 3111 in ; For example, Figure 17 In the figure, the cylindrical surface 31'' includes an arc 3111, an arc 3111' and a line segment 3112. The arc 3111 is tangentially connected between the line segment 3112 and the arc 3111'. In addition, the arc diameter of the arc 3111' is smaller than the arc diameter of the arc 3111. Therefore, by different designs of the directrix 311 (311', 311'') of the cylindrical surface 31 (31', 31''), different speeds of clamping the battery cell 200 and the force influence can be achieved, thereby reducing the risk of force influence on the side of the battery cell 200. It should be noted that although Figures 15 to 17It is shown that the directrix 311 (311', 311'') of the cylinder 31 (31', 31'') includes arcs and line segments. Obviously, according to actual needs, the directrix 311 (311', 311'') can also include only arcs or line segments. Figures 15 to 17 Limits shown.

[0045] like Figure 5 and Figure 13 As shown in FIG. 3 , as an example, the cover 30 is provided with a receiving cavity 32. In this case, the second pressing body 26 can be slidably assembled in the receiving cavity 32 along the thickness direction of the cover 30. The second restoring member 27 is located in the receiving cavity 32. The second restoring member 27 makes the second pressing body 26 partially protrude from the cover 30, thereby effectively preventing the cover 30 from contacting the battery cell 200 during the process of the second pressing body 26 pressing the battery cell 200. Specifically, Figure 5 and Figure 13 As an example, the side wall 321 of the accommodating cavity 32 is provided with a guide limit slot 322 for controlling the sliding range of the second pressing body 26. The second pressing body 26 is correspondingly provided with a guide limit piece 261 placed in the guide limit slot 322. By means of the cooperation between the guide limit piece 261 and the guide limit slot 322, the second pressing body 26 is prevented from accidentally falling off from the cover body 30, and a guide is provided for the sliding of the second pressing body 26 on the cover body 30, thereby improving the smoothness of the telescopic sliding of the second pressing body 26 on the cover body 30. More specifically, Figure 14 In the embodiment, the guide limiter 261 is inserted into the second pressing body 26, and its two ends extend out of the second pressing body 26. Correspondingly, the two opposite side walls 321 of the accommodating cavity 32 are provided with guide limiter slots 322 to achieve the guide limiter on the two opposite sides of the second pressing body 26. In addition, the guide limiter 261 is inserted into the second pressing body 26, and its two ends extend out of the second pressing body 26. Correspondingly, the number of guide limiters 261 used when guiding and limiting on both sides is simplified. In addition, the second reset member 27 is a compression spring elastically abutting against the cavity end wall 323 of the accommodating cavity 32 and between the second pressing body 26. Optionally, Figure 14 As an example, the second pressing body 26 is provided with a sleeve cavity 262 for the compression spring to be sleeved, and the cavity opening of the sleeve cavity 262 faces the cavity end wall 323 of the accommodating cavity 32. This design makes the expansion and contraction deformation of the second reset member 27 smoother and more reliable. It should be noted that although Figure 13 It is shown that the guide limit slot 322 is opened by the cavity side wall 321 and the guide limit member 261 is provided by the second top pressure body 26; Obviously, according to actual needs, the positions of the guide limit slot 322 and the guide limit member 261 can be swapped, that is, the guide limit slot 322 is opened by the second top pressure body 26, and the guide limit member 261 is provided by the cavity side wall 321, so it is not necessary to Figure 13The illustration is limited; in addition, the second reset member 27 may also be composed of two magnets arranged to repel each other magnetically.

[0046] In order to make the first pressing body 23 and the second pressing body 26 better protect the battery cell 200 from the pressing, Figure 8 As an example, the first pressing body 23 is provided with a first protective film structure 232, the part of the second pressing body 26 protruding from the cover body 30 is made into a second protective film structure 263, and the pushing body 40 is provided with a third protective film structure 42; the first protective film structure 232, the second protective film structure 263 and the third protective film structure 42 are all made of anti-static materials, but are not limited to this.

[0047] like Figures 1 to 5 As shown, as an example, one side of the carrier body 10 has the same orientation as the positioning structure 12 (for example, but not limited to Figures 1 to 5 The cover 30 has a first lug 13 and a second lug 14 spaced apart along the first direction. A pivoting protrusion 30a is provided on one side of the cover 30 and is disposed between the first lug 13 and the second lug 14. The pivoting protrusion 30a is pivotally connected to the first lug 13 and the second lug 14 to form the aforementioned rotation center line C1. As an example, Figures 3 to 5 In the embodiment, the pivoting projection 30a is pivotally connected to the first and second lugs 13, 14 via a shaft 15. One end of the shaft 15 is fixedly connected to the first lug 13, and the other end of the shaft 15 is fixedly connected to the second lug 14. In this case, the pivoting projection 30a rotates about the shaft 15, and the axis of the shaft 15 forms the rotation centerline C1. Obviously, the shaft 15 can also be fixed to the pivoting projection 30a, and the ends of the shaft 15 are then pivotally connected to the first and second lugs 13, 14, respectively. When the cover 30 is provided with the pivoting projection 30a, the main top surface 31 is located on the pivoting projection 30a. By virtue of the pivoting projection 30a being simultaneously pivotally connected to the first and second lugs 13, 14, both sides of the pivoting projection 30a are supported, thereby improving the reliability and smoothness of the rotation of the cover 30.

[0048] like Figures 1 to 5 and Figure 9 As shown in FIG. 1 , as an example, the carrier body 10 is provided with a hook 70 that can be released, and the cover 30 is provided with a locking structure 80 that cooperates with the hook 70; with the help of the hook 70 and the locking structure 80, the cover 30 and the carrier body 10 are locked together after closing, preventing the cover 30 from opening accidentally. Figure 9As an example, the card matching structure 80 is provided with a first inclined surface 81, and the hook 70 is provided with a second inclined surface 71 that matches the first inclined surface 81. When the cover 30 is closed, the first inclined surface 81 pushes the second inclined surface 71 to make the hook 70 slide along the card removal direction, thereby making it more convenient for the hook 70 to automatically engage with the card matching structure 80. More specifically, Figures 1 to 6 As an example, the hook 70 is fixed on the operating rod 72 and forms an integral structure with the operating rod 72. In addition, a return spring 73 is provided between the operating rod 72 and the carrier body 10. Figure 9 As shown, when the operator releases the force on the operating rod 72, the reset spring 73 drives the operating rod 72 to slide and reset the hook 70 together. Figure 9 As an example, the operating rod 72 is slidably mounted on the carrier body 10 along the first direction, but the present invention is not limited thereto. It should be noted that although the accompanying drawings show that the hook 70 is provided on the carrier body 10 and the engaging structure 80 is provided on the cover 30, it is clear that, depending on actual needs, the positions of the hook 70 and the engaging structure 80 can also be reversed, that is, the hook 70 is provided on the cover 30 and the engaging structure 80 is provided on the carrier body 10. Therefore, the present invention is not limited to the drawings.

[0049] like Figure 4 and Figure 5 As shown, as an example, a magnet 60 is mounted on one side of the cover 30 adjacent to the rotation center line C1. The magnet 60 is opened to a preset position relative to the carrier body 10 (see FIG. Figure 1 and Figure 2 As shown in FIG, the magnet 60 is magnetically attracted to the carrier body 10, for example, to the side wall 16 of the carrier body 10, so that the cover 30 maintains the preset position, effectively improving the convenience of operation. It should be noted that, according to actual needs, the magnet 60 can be set on the carrier body 10, so it is not necessary to Figure 4 and Figure 5 Limits shown.

[0050] The working principle of the multi-directional top-pressing positioning carrier for battery cells or batteries of the present invention is described with reference to the accompanying drawings:

[0051] When you want to Figure 1 The cell or battery in the open state is switched to the position by the multi-directional top-pressing positioning carrier 100. Figure 6In the covered state shown, the battery cell 200 is first placed on the supporting structure 11 and positioned by the positioning structure 12; then, the cover body 30 is rotated around the rotation center line C1 to close the cover, and the main top surface 31 (31', 31'') of the rotating cover body 30, in cooperation with the first reset member 21, drives the top body 22 to drive the first pressing body 23 to slide close to the positioning structure 12 through the connecting rod 24, so that the sliding first pressing body 23, under the action of the force provided by the first reset member 21, jointly with the positioning structure 12, clamps the battery cell 200 carried by the supporting structure 11 from the first direction.

[0052] At the same time, in the process of the first pressing body 23 and the positioning structure 12 jointly clamping the battery cell 200 carried by the supporting structure 11 from the first direction, the cover body 30 also causes the second pressing body 26 to clamp the battery cell 200 carried by the supporting structure 11 from the third direction together with the supporting structure 11 from the direction opposite to the supporting structure 11, and the first pressing body 23, in cooperation with the pushing and resetting member 50, links the pushing body 40 to push and position the battery cell 200 carried by the supporting structure 11. Therefore, after the cover body 30 is closed, the final state of the battery cell 200 is shown in FIG. Figure 11 When the battery cell 200 is positioned and clamped, the hook 70 engages with the matching clamp structure 80 to prevent the cover 30 from rotating in the opening direction, the first reset member 21 and the push reset member 50 are in an extended state, and the second reset member 26 is in a compressed state.

[0053] When you want to Figure 6 The cell or battery in the covered state is switched to the position by the multi-directional top-pressing positioning carrier 100. Figure 1 In the open state shown, the operator operates the operating lever 72, so that the operating lever 72 pushes the return spring 73 to compress and drives the hook 70 to disengage from the matching structure 80, thereby allowing the cover 30 to rotate relative to the carrier body 10 around the rotation center line C1 to Figure 1 The state shown. Figure 1 During the state shown, the main top surface 31 (31', 31'') drives the support body 22 via the connecting rod 24 to drive the first pressing body 23 to slide away from the positioning structure 12. The sliding first pressing body 23 releases the pressure on the battery cell 200 and compresses the first reset member 21. In addition, the second pressing body 26 automatically resets under the reset force provided by the second reset member 27; and the pushing body 40 is driven by the first pressing body 23 to slide away from the battery cell 200 supported by the support structure 11. The sliding pushing body 40 compresses the pushing reset member 50. Figure 10 shown.

[0054] Compared with the prior art, during the closing process of the cover body 30 (30', 30''), the main top surface 31 (31', 31'') drives the top-bearing body 22 in conjunction with the first reset member 21 to drive the first top-pressing body 23 to slide close to the positioning structure 12 through the connecting rod 24. At the same time, the first top-pressing body 23 also drives the pushing body 40 in conjunction with the pushing reset member 50 to slide close to the battery cell 200 carried by the supporting structure 11. In the process of positioning and clamping the battery cell 200 carried by the supporting structure 11 in the second direction by the sliding first top-pressing body 23 and the positioning structure 12, the pushing body 40 also pushes and positions the battery cell 200 carried by the supporting structure 11 from the first direction, so that the battery cell 200 has a double reference edge effect. Therefore, the multi-directional top-pressing positioning carrier 100 for battery cells or batteries of the utility model has good compatibility, which is conducive to improving production efficiency. It can also be compatible with the positioning and clamping of battery cells 200 with large tolerances. In addition, since the pressing force of the first pressing body 23 on the battery cell 200 is controlled by the first restoring member 21 , the pressing force on the battery cell 200 has the advantage of being controllable.

[0055] In addition, Figure 8 In the figure, as an example, although the supporting structure 11 and the positioning structure 12 are shown to form an integrated structure together to simplify the manufacturing process of the supporting structure 11 and the positioning structure 12, it is obvious that according to actual needs, the supporting structure 11 and the positioning structure 12 can also be manufactured separately and then fixed together by assembly. In addition, although the accompanying drawings show the multi-directional top-pressure positioning carrier 100 for the battery cell or battery of the present invention for positioning and clamping the battery cell 200, it is obvious that it can also be adapted for positioning and clamping batteries. In addition, when the rolling bearing 25 is removed, the top body 22 and the main top surface 31 are in a linked cooperation. Finally, the push-pushing reset member 50 can be a spring or composed of two magnets with mutually repelling magnetic forces. When the push-pushing reset member 50 is a spring, the spring is sheathed on the guide post 17 for the sliding of the push body 40, and the guide post 17 is provided by the carrier body 10.

[0056] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope covered by the present invention.
