Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery protection board technology, specifically a fully automatic calibration tool for lithium battery protection boards. Background Technology
[0002] As the name suggests, a battery protection board is an integrated circuit board that is mainly used to protect rechargeable batteries. The reason why lithium batteries need protection is determined by their own characteristics. Due to the material of lithium batteries, they cannot be overcharged, over-discharged, overcurrented, short-circuited, or charged and discharged at excessively high temperatures. Therefore, lithium battery components are always accompanied by a protection board with a sampling resistor and a current fuse. During the installation process, the battery protection board is usually connected and fixed to the lithium battery with double-sided tape before being fixed with ribbon cables.
[0003] However, during the connection and installation of the battery protection board and the lithium battery, the use of double-sided adhesive for fixing means that time is required for alignment when connecting the battery protection board. Moreover, manual positioning can easily lead to positional shifts or tilting after connection, making it impossible to ensure that the battery protection board and the lithium battery are in a parallel state. This can cause the boards to tilt during subsequent wiring, which not only affects wiring efficiency but also makes it easy for the wires to fall off over time, making installation quite troublesome. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a fully automatic calibration tool for lithium battery protection boards. It has a calibration effect, improves the parallelism of lithium battery protection board installation, reduces installation difficulty and improves installation convenience, and also has a reinforcement effect, improving installation efficiency and strength, thus solving the aforementioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic calibration tool for a lithium battery protection board, comprising a fixing plate, a reinforcing plate movably mounted on the rear side of the fixing plate, L-shaped plates fixedly mounted on the left and right sides of the fixing plate, a telescopic rod provided on the opposite side of the L-shaped plates, a limiting plate fixedly mounted on the end of the telescopic rod away from the L-shaped plates, a protection board body being installed on the opposite side of the limiting plate by snap-fit, an mounting plate fixedly mounted on the rear end of the L-shaped plates, a positioning plate movably mounted on the opposite side of the mounting plate, and a lithium battery body being installed on the opposite side of the positioning plate by snap-fit.
[0008] Preferably, the rear side of the fixing plate has a groove, the size and shape of which match the reinforcing plate, and the inner side of the groove has a through hole, on which a nut is fixedly installed. Handles are fixedly installed at the left and right ends of the front side of the fixing plate, respectively.
[0009] With the above technical solution, during use, the size and shape of the groove match the reinforcing plate, which facilitates the movement of the reinforcing plate inside the groove, making it easy to accommodate and adjust. Furthermore, the nut facilitates the reinforcement of the protective plate body in the later stages.
[0010] Preferably, a screw is movably mounted on the front side of the reinforcing plate via a bearing, a nut is threadedly connected to the outer side of the screw, and an adjusting valve is fixedly mounted on the end of the screw away from the reinforcing plate.
[0011] Through the above technical solution, during the reinforcement of the protection plate body, the regulating valve is rotated, and under the action of the thread, the screw moves inside the nut, thereby pushing the reinforcement plate closer to the protection plate body and continuing to move, so that the double-sided adhesive tape on the back of the protection plate body adheres to the lithium battery body, which can play a reinforcement role and avoid loosening due to unstable adhesion in later use.
[0012] Preferably, the L-shaped plate has grooves on opposite sides, and a slider is provided on the inner side of the groove. The telescopic rod includes an outer cylinder and an inner cylinder. The inner cylinder is movably installed on the outer cylinder, and a fastening spring is fixedly installed between the outer cylinder and the inner cylinder. A slider is fixedly installed at the end of the outer cylinder away from the limiting plate.
[0013] The above technical solution allows the protective plate body to be engaged with two limiting plates. During the engagement process, the inner cylinder slides inside the outer cylinder by squeezing. After the protective plate body is engaged, the inner cylinder and limiting plates are pushed closer to the protective plate body by the action of the fastening spring, which facilitates centered and fixed engagement. This improves the installation accuracy of the protective plate body and makes it easier to clamp and fix protective plate bodies of different specifications.
[0014] Preferably, the mounting plate has mating grooves on opposite sides, the size and shape of which match the positioning plate, and each of the four corners of the inner side of the mating groove has a movable hole.
[0015] Through the above technical solution, the positioning plate can be easily moved and adjusted in the positioning groove during the positioning and installation process, and the two sets of movable holes help to improve the stability of the positioning plate when it moves.
[0016] Preferably, a limiting rod is fixedly installed on the side of the positioning plate near the fitting groove. The limiting rods are arranged in groups of four, with a total of two groups. The limiting rods are movably installed inside the movable hole. A positioning spring is fixedly installed between the side of the mounting plate away from the positioning plate and the limiting rod.
[0017] With the above technical solution, during installation, the two positioning plates are aligned with the two sides of the lithium battery body, and then the alignment tool is pushed to make the positioning plates squeeze and engage with the lithium battery body. At this time, under the action of the positioning spring, the positioning plates are reset, so that the positioning plates are tightly attached to the two sides of the lithium battery body, thereby completing the positioning and alignment installation. This ensures that the installation position of the protection board body is centered and parallel to the lithium battery body, making the installation convenient and quick.
[0018] Compared with the prior art, this utility model provides a fully automatic calibration tool for lithium battery protection boards, which has the following advantages:
[0019] 1. This utility model engages the protective plate body with two limiting plates. During the engagement process, the inner cylinder slides inside the outer cylinder by squeezing. After engaging the protective plate body, the inner cylinder and the limiting plates are pushed close to the protective plate body by the action of the fastening spring, which facilitates the centering and fixing engagement. This helps to improve the installation accuracy of the protective plate body and facilitates the clamping and fixing of protective plate bodies of different specifications. Then, double-sided tape is pasted on the back side of the protective plate body.
[0020] 2. This utility model allows users to hold two sets of handles, align the two positioning plates with the two sides of the lithium battery body, and then push the calibration tool to press and engage the positioning plates with the lithium battery body. At this time, the positioning spring will cause the positioning plates to reset, so that the positioning plates are tightly attached to the two sides of the lithium battery body, thereby completing the positioning calibration installation. This ensures that the installation position of the protection board body is centered and parallel to the lithium battery body, making the installation convenient and quick, reducing the installation difficulty and improving the installation accuracy.
[0021] 3. This utility model uses the rotating regulating valve to move the screw inside the nut under the action of the thread, thereby pushing the reinforcing plate closer to the protective plate body and continuing to move, so that the double-sided adhesive tape on the back of the protective plate body can be attached to the lithium battery body, which can play a reinforcing role and prevent loosening caused by unstable adhesion in later use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1:
[0030] like Figure 1-5 As shown, the fully automatic calibration tool for lithium battery protection boards provided by this utility model includes a fixing plate 1, a reinforcing plate 2 movably installed on the rear side of the fixing plate 1, L-shaped plates 3 fixedly installed on the left and right sides of the fixing plate 1 respectively, a telescopic rod 4 provided on the opposite side of the L-shaped plates 3, a limiting plate 5 fixedly installed on the end of the telescopic rod 4 away from the L-shaped plates 3, a protection board body 7 being installed on the opposite side of the limiting plate 5 by snap-fit, an mounting plate 8 fixedly installed on the rear end of the L-shaped plates 3, a positioning plate 9 movably installed on the opposite side of the mounting plate 8, and a lithium battery body 10 being installed on the opposite side of the positioning plate 9 by snap-fit.
[0031] Specifically, a groove 101 is provided on the rear side of the fixing plate 1. The size and shape of the groove 101 fits the reinforcing plate 2, and a through hole 102 is provided on the inner side of the groove 101. A nut 103 is fixedly installed inside the through hole 102. Handles 104 are fixedly installed on the left and right ends of the front side of the fixing plate 1, respectively. The advantage is that the size and shape of the groove 101 fits the reinforcing plate 2, which facilitates the movement of the reinforcing plate 2 inside the groove 101 during use, thereby facilitating its accommodation and adjustment. Furthermore, the nut 103 facilitates the reinforcement of the protective plate body 7 in the later stages.
[0032] Specifically, a screw 201 is movably mounted on the front side of the reinforcing plate 2 via a bearing. A nut 103 is threadedly connected to the outer side of the screw 201, and an adjusting valve 202 is fixedly mounted on the end of the screw 201 away from the reinforcing plate 2. The advantage is that by rotating the adjusting valve 202, the screw 201 moves inside the nut 103 under the action of the thread, thus pushing the reinforcing plate 2 closer to the protective plate body 7 and continuing to move. This allows the double-sided adhesive tape on the rear side of the protective plate body 7 to adhere to the lithium battery body 10, providing reinforcement and preventing loosening due to unstable adhesion during later use.
[0033] Specifically, the L-shaped plate 3 has grooves 301 on opposite sides, and a slider is provided on the inner side of the grooves 301. The telescopic rod 4 includes an outer cylinder 401 and an inner cylinder 402. The inner cylinder 402 is movably installed on the outer cylinder 401, and a fastening spring is fixedly installed between the outer cylinder 401 and the inner cylinder 402. A slider is fixedly installed at the end of the outer cylinder 401 away from the limiting plate 5. The advantage is that by engaging the protective plate body 7 with the two limiting plates 5, the inner cylinder 402 slides inside the outer cylinder 401 by squeezing during the engagement process. After engaging the protective plate body 7, the inner cylinder 402 and the limiting plate 5 are pushed closer to the protective plate body 7 by the fastening spring, which facilitates centered and fixed engagement. This improves the installation accuracy of the protective plate body 7 and facilitates clamping and fixing of protective plate bodies 7 of different specifications.
[0034] Example 2:
[0035] like Figure 1-5 As shown, as an improvement on the previous embodiment, specifically, the mounting plate 8 has mating grooves 801 on opposite sides, the size and shape of which match the positioning plate 9, and each of the four corners of the inner side of the mating groove 801 has a movable hole 802. The advantage is that the mating grooves 801 facilitate the movement and adjustment of the positioning plate 9 during the positioning and installation process, and the two sets of movable holes 802 help improve the stability of the positioning plate 9 during movement.
[0036] Specifically, a limiting rod 901 is fixedly installed on the side of the positioning plate 9 near the mating groove 801. Two sets of limiting rods 901 are arranged in groups of four, and the limiting rods 901 are movably installed inside the movable hole 802. A positioning spring 902 is fixedly installed between the side of the mounting plate 8 away from the positioning plate 9 and the limiting rod 901. The advantage is that by aligning the two positioning plates 9 with the sides of the lithium battery body 10, and then pushing the alignment tool, the positioning plates 9 and the lithium battery body 10 are pressed and engaged. At this time, under the action of the positioning spring 902, the positioning plates 9 are reset, thus tightly adhering to the sides of the lithium battery body 10, thereby completing the positioning and alignment installation. This ensures that the installation position of the protection plate body 7 is centered and parallel to the lithium battery body 10, making installation convenient and quick.
[0037] During use, the protective plate body 7 is engaged with the two limiting plates 5. During engagement, the inner cylinder 402 slides inside the outer cylinder 401 by pressing. After engaging the protective plate body 7, the inner cylinder 402 and the limiting plates 5 are pushed closer to the protective plate body 7 by the action of the fastening spring, thus facilitating centered engagement. This improves the installation accuracy of the protective plate body 7 and facilitates clamping and fixing of protective plate bodies 7 of different specifications. Double-sided tape is then attached to the back of the protective plate body 7. Next, by holding the two sets of handles 104, the two positioning plates 9 are aligned with the two sides of the lithium battery body 10. Then, the alignment tool is pushed, causing the positioning plates 9 to be pressed and engaged with the lithium battery body 10. At this time, the positioning spring 90... Under the action of 2, the positioning plate 9 is reset, which in turn makes the positioning plate 9 tightly fit against both sides of the lithium battery body 10, thereby completing the positioning and correction installation. This ensures that the installation position of the protection plate body 7 is centered and parallel to the lithium battery body 10, making installation convenient and quick, reducing installation difficulty and improving installation accuracy. Then, by rotating the regulating valve 202, the screw 201 moves inside the nut 103 under the action of the thread, which pushes the reinforcing plate 2 closer to the protection plate body 7 and continues to move, so that the double-sided adhesive tape on the back of the protection plate body 7 is attached to the lithium battery body 10, which can play a reinforcing role and prevent loosening caused by unstable adhesion in later use. Then, the wiring can be connected. In the parallel state without deviation, it can effectively prevent the wires from lifting or falling off.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
