Description

Technical Field

[0001] The utility model relates to the field of new energy batteries, in particular to a CTP battery cell box-entry anti-falling clamping claw structure. Background Art

[0002] CTP (Cell to Pack) technology integrates cells directly into battery packs, eliminating the module component of the traditional three-tiered "cell-module-battery pack" structure. With the development of new energy batteries, research on CTP cells is increasing to improve battery pack energy density and space utilization while reducing component usage. Safely packaging CTP cells is a key issue.

[0003] Existing CTP battery cell loading systems typically use sponge suction cups to absorb the top surface of the CTP battery cell. After transporting it into the box, the suction is released to allow the CTP battery cell to be loaded into the box. However, due to the varying shapes and sizes of produced CTP batteries, custom-made sponge suction cups are required to absorb the CTP battery cell, resulting in a long production cycle. Furthermore, the existing loading system lacks a bottom support device, which can cause the CTP battery cell to fall during transport.

[0004] The CTP battery cell boxing structure in the prior art has low compatibility because one sponge suction cup can only adapt to one CTP battery cell, and has low safety because there is no bottom protection device. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Figures 1 to 9The illustrated structure of a CTP battery cell anti-falling clamp comprises: a handle 1, a positive and negative threaded screw rod 2, a nut seat 3, a top plate 4, a first guide rail 51, a first transmission plate 61 and a bottom anti-falling assembly 7. The top plate 4 is arranged horizontally and has a rectangular structure. The positive and negative threaded screw rod 2 is rotatably arranged on the top plate 4 along the width direction of the top plate 4. The handle 1 is arranged at one end of the positive and negative threaded screw rod 2. The nut seat 3, the first guide rail 51, the first transmission plate 61 and the bottom anti-falling assembly 7 are all provided in two groups and are symmetrically arranged along the length direction of the top plate 4. The two nut seats 3 are respectively arranged on the positive and negative threads of the positive and negative threaded screw rod 2. The top plate 4 is provided with a plurality of nut seats 3, ... The bottom of the plate 4 is provided with a first guide rail 51 along the width direction of the top plate 4, the first transmission plate 61 is arranged horizontally and fixedly connected to the nut seat 3, the first transmission plate 61 is slidably set on the first guide rail 51, the first transmission plate 61 has a rack 611 along the direction of the forward and reverse screw rods 2, the bottom anti-fall assembly 7 includes a gear 71, a gear rod 72 and a right-angle clamp 73, the gear 71 cooperates with the rack 611, the gear rod 72 is arranged perpendicular to the direction of the forward and reverse screw rods 2, the gear rod 72 is rotatably set at the bottom of the top plate 4, and one end of the gear 71 and the right-angle clamp 73 is fixed on the gear rod 72.

[0032] For example, in the embodiment of the present invention, the right-angle clamp 73 includes a first connecting rod 731 and a second connecting rod 732, and the first connecting rod 731 and the second connecting rod 732 are perpendicular to each other. By rotating the driving handle 1, the positive and negative thread rods 2 are rotated. The threads at both ends of the positive and negative thread rods 2 are in opposite directions. When rotating, the two nut seats 3 located on the threads at both ends move in opposite directions at the same time. Figure 8 and Figure 9 As shown, Figure 8 This is a side view of the right-angle clamp provided by the embodiment of the present invention when it is closed. Figure 9 This is a side view of the right-angle clamp provided by the embodiment of the present invention when it is open. Figure 8 As shown, in the initial state, the first connecting rod 731 is in a vertical state, and the second connecting rod 732 is in a horizontal state. The first guide rail 51 is a convex guide rail, and a concave groove matching the first guide rail 51 is provided above the first transmission plate 61. The first guide rail 51 can provide a guide for the movement of the first transmission plate 61. When the handle 1 is rotated to make the two nut seats 3 move away from each other, the first transmission plates 61 on both sides of the top plate 4 move away from each other. At this time, the rack 611 on the right side of the figure moves to the right, driving the gear 71 on the right side of the figure to rotate counterclockwise. At this time, the gear rod 72 and the right-angle clamp 73 also rotate counterclockwise, so that the first connecting rod 731 is in a horizontal state and the second connecting rod 732 is in a vertical state. At this time, the nut seat 3, the first guide rail 51, the first transmission plate 61 and the bottom anti-fall assembly 7 on the left side of the figure also move in a mirrored manner, so that the two right-angle clamps 73 open, so that this structure is formed as shown. Figure 9The state shown is convenient for placing the CTP battery cell between the two right-angle clamps from above. When the CTP battery cell is located between the two right-angle clamps 73, the handle 1 is rotated in the opposite direction so that the two nut seats 3 and the two first transmission plates 61 move closer to each other, thereby driving the gear 71 on the right side of the figure to rotate clockwise. At this time, the gear rod 72 and the right-angle clamp 73 also rotate clockwise, so that the first connecting rod 731 returns to the vertical state and the second connecting rod 732 returns to the horizontal state. At this time, the nut seat 3, the first guide rail 51, the first transmission plate 61 and the bottom anti-fall assembly 7 on the left side of the figure also move in a mirror image, so that the two right-angle clamps 73 are closed, clamping the CTP battery cell inside it, so that the present structure returns to the state as shown. Figure 8 The CTP battery cell can now be transported. When it is time to place it in a box, the above movement is repeated, opening the two right-angled jaws 73, allowing the CTP battery cell to fall into the box due to gravity. The right-angled jaws 73 can be rotated around the gear rod 72 by driving the handle 1, so that the two right-angled jaws 73 can be opened and closed, thereby clamping and placing the CTP battery cell in the box.

[0033] The embodiment of the present invention provides a CTP battery cell box anti-falling clamping claw structure, which drives the forward and reverse screw rods 2 to rotate by driving the handle 1, so that the two nut seats 3 move in opposite directions, and drive the first transmission plate 61 and the rack 611 thereon to move in opposite directions, so that the rack 611 drives the gear 71, the gear rod 72 and the right-angle clamping claw 73 to rotate, thereby opening the right-angle clamping claws 73 on both sides of the top plate 4, making it convenient to put the CTP battery cell between the two bottom anti-falling components 7, and then rotate the handle 1 in the opposite direction to make the CTP battery cell The right-angle clamping jaw 73 is rotated in the opposite direction and closed, so that the right-angle clamping jaw 73 lifts the CTP battery cell from the bottom of the CTP battery cell, thereby realizing the bottom protection and anti-falling function of the CTP battery cell. Since the right-angle clamping jaws 73 on both sides have a certain distance, they can be compatible with CTP battery cells of a certain size. At the same time, since the right-angle clamping jaw 73 is easy to manufacture and disassemble, the right-angle clamping jaw 73 can also be replaced according to the size of the CTP battery cell to adapt to CTP battery cells of different sizes, which can effectively solve the problems of low compatibility and low safety in the existing technology.

[0034] Optionally, a plurality of right-angle clamping jaws 73 are provided, and the plurality of right-angle clamping jaws 73 are spaced apart along the direction of the gear rod 72 .

[0035] For example, in an embodiment of the present invention, by providing a plurality of right-angle clamps 73 on each side, the right-angle clamps 73 can be made more stable when lifting the CTP battery cell from the bottom, preventing the CTP battery cell from falling due to unstable center of gravity, thereby improving the stability of the structure.

[0036] Optionally, a support plate 74 is provided at one end of the right-angle clamping jaw 73 away from the gear rod 72 .

[0037] For example, in an embodiment of the present invention, by providing a support plate 74, when clamping the CTP battery cell, the CTP battery cell is clamped onto the support plate 74, which can increase the force area of the CTP battery cell during clamping, so that during the clamping process, the CTP battery cell is more stably in the right-angle clamping claw 73, thereby further improving the stability of the structure.

[0038] Optionally, a large-surface clamping mechanism 8 is provided at the bottom of the top plate 4. The large-surface clamping mechanism 8 includes a reference portion 81 and a movable portion 82. The reference portion 81 and the movable portion 82 are respectively provided at both ends of the gear rod 72. The reference portion 81 is fixedly connected to the top plate 4, and the movable portion 82 is configured to move close to or away from the reference portion 81.

[0039] For example, in an embodiment of the present invention, after the bottom anti-fall component clamps the CTP battery cell from both sides, the CTP battery cell is further clamped from both ends by the large-surface clamping mechanism 8 located at both ends of the CTP battery cell. The movable part 82 can also be controlled to move by installing a screw crank structure. By controlling the movable part 82 to move toward the reference part 81, the CTP battery cell is displaced in the length direction to one end and is in close contact with the reference part 81. At this time, the reference part 81 and the movable part 82 clamp it in the length direction of the CTP. By setting the large-surface clamping mechanism 8, the stability of this structure is further improved.

[0040] Optionally, a pressure sensor 83 is provided on the reference portion 81 .

[0041] For example, in this embodiment of the present invention, by providing a pressure sensor 83, it is possible to monitor the force exerted by the movable portion 82 when pushing the CTP cell toward the reference portion 81. This prevents the CTP cell from being squeezed and damaged if the movable portion 82 continues to move toward the reference portion 81 after the CTP cell has been clamped by the reference portion 81 and the movable portion 82. The provision of the pressure sensor 83 not only ensures the stability of the device, but also provides additional protection for the CTP cell.

[0042] Optionally, it also includes a horizontally arranged second transmission plate 62, two second transmission plates 62 are provided, and are symmetrically arranged along the length direction of the top plate 4, the second transmission plate 62 is arranged below the first transmission plate 61, and a second guide rail 52 along the width direction of the top plate 4 is provided on the top of the second transmission plate 62, the second transmission plate 62 is slidably provided on the second guide rail 52, a first limit block 612 is provided at the bottom of the first transmission plate 61, and a second limit block 621 matching the first limit block 612 is provided at the top of the second transmission plate 62, a vertically downward spring mounting seat 41 is provided at the bottom of the top plate 4, and horizontal springs 9 are respectively provided between the spring mounting seat 41 and the two second limit blocks 621.

[0043] For example, in the embodiment of the present invention, Figure 1 and Figure 2 As shown, each second transmission plate 62 is provided with a vertical clamping plate 622 at the bottom, with two clamping plates 622 arranged toward the CTP battery cells. A vertical, downward-facing spring mounting post 623 is provided at the bottom of each second transmission plate 62. One end of the spring 9 is mounted on the spring mounting seat 41, and the other end is mounted on the spring mounting post 623. In the initial state, the spring 9 is in a natural position, the first stop 612 is located on the inner side, and the second stop 621 is located on the outer side. There is a slight gap between the first stop 612 and the second stop 621. The second guide rail 52 is a concave guide rail. The bottom of the first transmission plate 61 is provided with a protrusion that matches the second guide rail 52. The second guide rail 52 serves as a guide for the movement of the second transmission plate 62. When the nut seat 3 drives the two first transmission plates 61 to move away from each other, the first limit block 612 moves toward the second limit block 621. When the first limit block 612 contacts the second limit block 621, they continue to move toward each other, causing the first limit block 612 to drive the second limit block 621 to move outward, thereby causing the two second limit blocks 621 to move away from each other, causing the two clamping plates 622 to open. At this time, the spring 9 is in a stretched state. After the bottom anti-fall assembly 7 clamps the CTP battery cell, the CTP battery cell is located between the two clamping plates 622. Under the elastic force of the spring 9, the clamping plates 622 apply a clamping force to the side of the CTP battery cell, thereby making the CTP battery cell more stably fixed below the top plate 4. By providing the second transmission plate 62 to cooperate with the first transmission plate 61, the stability of the present structure can be further improved.

[0044] Optionally, the number of springs 9 between the spring mounting seat 41 and the two second limiting blocks 621 is different.

[0045] For example, in the embodiment of the present invention, Figure 5As shown, there are three springs between the spring mounting seat 41 and one of the second limit blocks 621, and two springs between the spring mounting seat 41 and the other second limit block 621. The clamping force applied to the CTP cell by the clamping plates 622 on both sides is applied by springs 9. When the number of springs 9 on both sides is the same, the clamping force applied to the CTP cell on both sides is consistent. When a slight shake occurs, the clamping force on both sides is easily unbalanced, causing the clamping force to cause the CTP cell to flip. When the clamping forces on both sides are different, one end becomes the fixed end and the other end becomes the clamping end, allowing the CTP cell to be more stably clamped between the two clamping plates 622, thereby further improving the stability of the present structure.

[0046] Optionally, a scale bar 101 is provided on the top plate 4 along the width direction, and a pointer 102 matching the scale bar 101 is provided on the nut seat 3 .

[0047] For example, in the embodiment of the present invention, Figure 4 As shown, by setting the scale bar 101 and the pointer 102, the displacement of the nut seat 3 can be accurately measured. When clamping a batch of CTP batteries of the same size, the displacement of the nut seat 3 can be remembered, so that the operator only needs to rotate the handle 1 to a certain extent, without having to rotate it to the maximum stroke, thereby reducing the operator's manual work, thereby improving the operational convenience of the present structure.
