Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to a battery protection board pressure holding mechanism. Background Technology

[0002] During the production of battery modules, the flexible circuit board portion of the battery protection board typically needs to be bent into a predetermined shape to accommodate the battery structure layout. However, the flexible circuit board material itself is elastic, and after bending, it generates rebound stress, making it difficult for the flexible circuit board to maintain the required bending state stably. Therefore, in actual processes, it is usually necessary to perform a pressure holding process on the flexible circuit board after bending to maintain its shape stability.

[0003] Currently, most common pressure holding devices use simple planar clamping structures. For complex bending structures, such as when the bending part and the soft board body have an angle in the height direction, existing pressure holding devices cannot achieve effective positioning and reliable pressure holding. This can cause the product to easily shift due to uneven force, affecting product quality and assembly consistency. Utility Model Content

[0004] The purpose of this utility model is to provide a battery protection board pressure holding mechanism that can effectively position and hold pressure on the product, avoid rebound, and improve the quality and reliability of the product.

[0005] A battery protection board pressure holding mechanism includes a positioning seat, a supporting component, and a pressure holding component. The positioning seat has a positioning part for placing the battery protection board. The supporting component and the pressure holding component are disposed opposite to each other on both sides of the positioning part. The supporting component is configured to abut against and fix the battery protection board from one side. The positioning seat has a first pressure holding inclined surface on the side facing the pressure holding component. The pressure holding component is configured to approach the positioning part from the other side to clamp the part of the battery protection board to be pressure held between the first pressure holding inclined surface and the pressure holding component.

[0006] In the above technical solution, the positioning part is used to place the battery protection board. When the battery protection board is placed in the positioning part, the flexible board part to be pressed extends out of the positioning part and faces the first pressing inclined surface. The holding component and the pressing component are arranged opposite to each other on both sides of the positioning part. The holding component can reliably fix the battery protection board from one side first. Then the pressing component approaches the positioning part from the other side and, together with the first pressing inclined surface, presses the flexible board part tightly, thereby achieving precise and effective pressing of the battery protection board. This ensures that the positioning is stable and the force is reasonable during the pressing process, thereby improving the pressing quality and consistency, ensuring the stable forming shape of the battery protection board, and avoiding springback.

[0007] Furthermore, the pressure holding assembly includes a pressure holding drive, a sliding seat, a pressure block, and a first elastic element. The output end of the pressure holding drive is connected to the sliding seat, the pressure block is slidably connected to the sliding seat, and the first elastic element is disposed between the pressure block and the sliding seat.

[0008] In the above technical solution, the pressure holding component adopts a pressure holding drive, a sliding seat, a pressure block and a first elastic element to cooperate, so that the pressure block can approach the positioning part for pressing under the drive of the pressure holding drive. At the same time, the first elastic element can achieve buffering and adaptive pressing, avoiding the pressure block from causing hard impact or damage to the battery protection board, thus improving the safety and reliability of the pressure holding process.

[0009] Furthermore, the pressure block is provided with a second pressure-holding slope that matches the first pressure-holding slope.

[0010] In the above technical solution, a second pressure-holding inclined surface matching the first pressure-holding inclined surface is provided on the pressure block, so that when the pressure block approaches the positioning seat, the cooperation of the two inclined surfaces can press the battery protection board at a preset angle and ensure uniform pressing force.

[0011] Furthermore, the abutment component includes an abutment drive component and an abutment block. The positioning seat is provided with a groove, and the abutment block is slidably disposed in the groove. The abutment drive component is disposed below the positioning seat and is used to drive the abutment block to slide along the groove.

[0012] In the above technical solution, by setting the abutment block in the groove of the positioning seat and driving it to slide by the drive component below, the vertical space of the positioning seat is effectively utilized, thus making the structure more compact. The groove can constrain the movement trajectory of the abutment block, making its operation smooth and accurately and reliably abutting or releasing the battery protection plate, realizing rapid and accurate positioning and fixing of the workpiece.

[0013] Furthermore, the abutment drive assembly includes an abutment drive member and a drive block. The output end of the abutment drive member is connected to the drive block. The lower end of the abutment block is provided with a first inclined surface, and the drive block is provided with a second inclined surface that cooperates with the first inclined surface. The abutment drive member is used to drive the drive block to move in the vertical direction, so as to move the abutment block away from the positioning part.

[0014] In the above technical solution, the abutment drive assembly utilizes the vertical movement of the drive block and, through cooperation with the inclined surface on the abutment block, transforms it into the horizontal sliding of the abutment block. This drive method has a compact structure, effectively utilizes the space below the positioning seat, reduces the lateral dimension of the mechanism, and at the same time, the inclined surface transmission can achieve self-locking, ensuring the stability and reliability of the position of the abutment block when fixing the battery protection board.

[0015] Furthermore, the positioning seat is provided with a baffle at one end of the slide groove, and a second elastic element is provided between the baffle and the abutment block.

[0016] In the above technical solution, a baffle is set at one end of the slide and a second elastic member is set between it and the abutment block. This structure allows the second elastic member to automatically push the abutment block towards the positioning part after the drive component releases the driving force, maintaining the positioning of the battery protection board, simplifying the operation process and improving the cycle efficiency and automation of the mechanism.

[0017] Furthermore, the end of the abutment block facing the positioning part is provided with an abutment end for abutting against the battery protection plate.

[0018] In the above technical solution, a supporting end is provided on the side of the supporting block facing the positioning part, so that the supporting part matches the contour of the battery protection board, making the supporting force distribution more uniform and avoiding deformation or damage to the flexible board due to stress concentration. At the same time, the special supporting end shape can better adapt to the shape of the flexible board and improve the reliability of fixing.

[0019] Furthermore, a limiting block is provided on the side of the positioning part away from the abutment component, and a portion of the limiting block extends to the positioning part and is disposed opposite to the abutment block.

[0020] In the above technical solution, a limiting block extending to the positioning part is provided on the side of the positioning part away from the supporting component, so that it is opposite to the supporting block, which can reliably limit the battery protection board and prevent it from shifting or sliding due to force during the pressure holding process, thereby further ensuring the accuracy of the pressure holding position.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: The positioning part is used to place the battery protection board. When the battery protection board is placed in the positioning part, the soft board part to be pressed extends out of the positioning part and faces the first pressing inclined surface. The holding component and the pressing component are arranged opposite to each other on both sides of the positioning part. The holding component can reliably fix the battery protection board from one side first. Then the pressing component approaches the positioning part from the other side and, together with the first pressing inclined surface, presses the soft board part tightly, thereby achieving precise and effective pressing of the battery protection board. This ensures that the positioning is stable and the force is reasonable during the pressing process, thereby improving the pressing quality and consistency, ensuring the stable forming shape of the battery protection board, and avoiding springback.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Please refer to Figures 1 to 5 In a preferred embodiment, the battery protection board 5 pressure holding mechanism of this utility model mainly includes a positioning seat 1, a supporting component 2, and a pressure holding component 3. The positioning seat 1 has a positioning part 11 for placing the battery protection board 5. The supporting component 2 and the pressure holding component 3 are disposed opposite each other on both sides of the positioning part 11. The supporting component 2 is configured to abut against and fix the battery protection board 5 from one side. The positioning seat 1 has a first pressure holding inclined surface 12 on the side facing the pressure holding component 3. The pressure holding component 3 is configured to approach the positioning part 11 from the other side to clamp the portion of the battery protection board 5 to be pressure held between the first pressure holding inclined surface 12 and the pressure holding component 3.

[0031] For example, the positioning seat 1 is disposed on a platform 4, the positioning part 11 is located on the positioning seat 1, and the first pressure-holding inclined surface 12 is disposed adjacent to one side of the positioning part 11. The shape of the positioning part 11 matches the shape of the battery protection plate 5. When the battery protection plate 5 is placed on the positioning part 11, the soft plate part to be pressure-held extends out of the positioning part 11 from one side and faces the first pressure-holding inclined surface 12. The abutment component 2 and the pressure-holding component 3 are disposed opposite to each other on both sides of the positioning part 11. The abutment component 2 can reliably fix the battery protection plate 5 from one side first, and then the pressure-holding component 3 approaches the positioning part 11 from the other side, and cooperates with the first pressure-holding inclined surface 12 to press the part to be pressure-held of the battery protection plate 5, thereby achieving precise and effective pressure holding of the battery protection plate 5, ensuring stable positioning and reasonable force during the pressure holding process, thereby improving the pressure holding quality and consistency, ensuring the stable forming shape of the battery protection plate 5, and avoiding springback.

[0032] Please refer to Figure 2 The pressure holding assembly 3 includes a pressure holding drive 31, a sliding seat 32, a pressure block 33, and a first elastic member 34. The output end of the pressure holding drive 31 is connected to the sliding seat 32, the pressure block 33 is slidably connected to the sliding seat 32, and the first elastic member 34 is disposed between the pressure block 33 and the sliding seat 32.

[0033] For example, the pressure-holding drive 31 can be an existing linear drive device, such as a cylinder, with its output end connected to the sliding seat 32. The sliding seat 32 is slidably connected to the platform 4. The pressure-holding drive 31 can drive the sliding seat 32 to move horizontally, thereby moving closer to or away from the positioning seat 1. The pressure block 33 is slidably connected to the sliding seat 32 via a connecting rod. The first elastic element 34 can be a spring, which is compressed between the pressure block 33 and the sliding seat 32.

[0034] The pressure holding assembly 3 uses a pressure holding drive 31, a sliding seat 32, a pressure block 33 and a first elastic member 34 to cooperate, so that the pressure block 33 can approach the positioning part 11 for pressing under the drive of the pressure holding drive 31. At the same time, the first elastic member 34 can achieve buffering and adaptive pressing, avoiding the pressure block 33 from causing hard impact or damage to the battery protection board 5, thus improving the safety and reliability of the pressure holding process.

[0035] In this embodiment, the pressure block 33 is provided with a second pressure-holding inclined surface 331 that matches the first pressure-holding inclined surface 12. The second pressure-holding inclined surface 331 that matches the first pressure-holding inclined surface 12 is provided on the pressure block 33 so that when the pressure block 33 approaches the positioning seat 1, the cooperation of the two inclined surfaces can press the battery protection plate 5 at a preset angle and ensure uniform pressing force.

[0036] Please refer to Figure 3The supporting component 2 includes a supporting drive component 21 and a supporting block 22. The positioning seat 1 is provided with a slide groove 13, and the supporting block 22 is slidably disposed in the slide groove 13. The supporting drive component 21 is disposed below the positioning seat 1 and is used to drive the supporting block 22 to slide along the slide groove 13. By setting the supporting block 22 in the slide groove 13 of the positioning seat 1 and driving it to slide by the drive component below it, the vertical space of the positioning seat 1 is effectively utilized, thereby making the structure more compact. The slide groove 13 can constrain the movement trajectory of the supporting block 22, making its operation smooth and able to accurately and reliably tighten or loosen the battery protection plate 5, realizing the rapid and accurate positioning and fixing of the workpiece.

[0037] In this embodiment, the abutment drive assembly 21 includes an abutment drive member 211 and a drive block 212. The output end of the abutment drive member 211 is connected to the drive block 212. The lower end of the abutment block 22 is provided with a first inclined surface 221. The drive block 212 is provided with a second inclined surface 2121 that cooperates with the first inclined surface 221. The abutment drive member 211 is used to drive the drive block 212 to move in the vertical direction, so as to drive the abutment block 22 away from the positioning part 11.

[0038] For example, the abutment drive member 211 can be an existing linear drive device, such as a cylinder, which is located below the platform 4 and opposite to the positioning seat 1. It can drive the drive block 212 to move vertically. The second inclined surface 2121 of the drive block 212 applies pressure to the first inclined surface 221. The horizontal component of this pressure causes the abutment block 22 to slide along the slide groove 13 and move away from the positioning part 11, thereby realizing the opening of the battery protection board 5.

[0039] The abutment drive assembly 21 utilizes the vertical movement of the drive block 212, which, through its engagement with the inclined surface on the abutment block 22, transforms the vertical movement into the horizontal sliding of the abutment block 22. This drive method has a compact structure, effectively utilizes the space below the positioning seat 1, and reduces the lateral dimensions of the mechanism. At the same time, the inclined surface transmission can achieve self-locking, ensuring the stability and reliability of the position of the abutment block 22 when fixing the battery protection board 5.

[0040] In this embodiment, the positioning seat 1 has a baffle 14 at one end of the slide groove 13, and a second elastic member 15 is provided between the baffle 14 and the abutment block 22. The second elastic member 15 can be a spring, which is compressed between the baffle 14 and the abutment block 22. By providing a baffle 14 at one end of the slide groove 13 and a second elastic member 15 between it and the abutment block 22, this structure allows the second elastic member 15 to automatically push the abutment block 22 towards the positioning part 11 after the driving component releases the driving force, maintaining the positioning of the battery protection board 5. This simplifies the operation process and improves the cyclic efficiency and automation of the mechanism's actions.

[0041] The end of the abutment block 22 facing the positioning part 11 is provided with an abutment end 222 for abutting against the battery protection plate 5. The abutment end 222 is provided on the side of the abutment block 22 facing the positioning part 11 so that the abutment part matches the contour of the battery protection plate 5, making the abutment force distribution more uniform and avoiding deformation or damage to the flexible plate that may be caused by stress concentration. At the same time, the dedicated abutment end 222 can better adapt to the shape of the flexible plate and improve the reliability of fixation.

[0042] Please refer to Figure 4 and Figure 5 A limiting block 16 is provided on the side of the positioning part 11 away from the supporting component 2. A portion of the limiting block 16 extends into the positioning part 11 and is disposed opposite to the supporting block 22. By providing a limiting block 16 that partially extends into the positioning part 11 on the side of the positioning part 11 away from the supporting component 2, and making it opposite to the supporting block 22, the battery protection board 5 can be reliably limited, preventing it from shifting or sliding due to force during the pressure holding process, and further ensuring the accuracy of the pressure holding position.
