[0002] A lithium battery pack protection board is an integrated circuit board composed of electronic components such as control ICs, MOS switches, precision resistors, and capacitors. Moreover, the lithium battery pack protection board is an indispensable safety control module in a series lithium battery pack. Its core function is to monitor the battery status in real time and perform protective actions to prevent the battery from being damaged or causing safety accidents due to abnormal operating conditions.

[0003] Currently available lithium battery pack protection boards have the following problems when used:

[0004] 1. Traditional lithium battery pack protection boards are usually stacked directly on a table during transportation. Due to the complex structure of the circuit board surface, multiple circuit boards stacked together are prone to surface scratches, resulting in weak protection when idle.

[0005] 2. When handling most lithium battery pack protection boards, you often pinch the corners of the circuit board and move it. If it falls or slips during the handling process, its surface is easily damaged, making it relatively unstable when handling. Utility Model Content

[0006] The purpose of this utility model is to provide a lithium battery pack protection board to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A lithium battery pack protection board includes a protection board body and a mounting hole. The mounting hole is opened at the top of the protection board body, and a threaded groove is opened at the top of the protection board body. A threaded block is threadedly connected inside the threaded groove. A positioning sleeve is provided at the top of the threaded block. A positioning rod is embedded inside the positioning sleeve. A protective cover is provided at the top of the positioning rod. A transparent plate is embedded at the top of the protective cover, and a mesh plate is embedded on the outer side of the protective cover.

[0008] Preferably, the protective plate body is provided with a rubber frame on the outside, the rubber frame is connected to the rubber plate through a pivot, the rubber frame is provided with an anti-slip frame on the outside, the rubber plate is installed with anti-slip strips, the side of the rubber frame is provided with a slot, the inside of the rubber plate is provided with an insert block, and the insert block is embedded in the slot.

[0009] Preferably, the positioning sleeve has a groove inside, and the positioning rod has a block on the outside. The blocks are arranged in a ring and are embedded in the groove.

[0010] Preferably, the top of the positioning rod is provided with a fixing block, and the other side of the fixing block is provided with a protective cover.

[0011] Preferably, the inner side of the rubber frame is provided with a first magnetic absorbing sheet, and the outer side of the protective plate body is provided with a first metal sheet, wherein the first magnetic absorbing sheet magnetically attracts the first metal sheet.

[0012] Preferably, the rubber sheet has a second magnetic absorbing sheet on its inner side and the protective plate body has a second metal sheet on its outer side. The second magnetic absorbing sheet attracts the second metal sheet by magnetic force.

[0013] The lithium battery pack protection board of this utility model has the following advantages:

[0014] 1. This lithium battery pack protection board, by installing a positioning sleeve on the top of the protection board and embedding a positioning rod inside the positioning sleeve, and connecting a protective cover to the top of the positioning rod by a fixing block, facilitates the external protection of the lithium battery protection board. When the protection board is not in use, the operator removes the protective cover and embeds the positioning rod inside the protective cover into the positioning sleeve, thus protecting the idle protection board. The protection effect is strong when the board is not in use.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a lithium battery pack protection board according to this utility model.

[0028] like Figure 1-4 As shown, this utility model discloses a lithium battery pack protection board, including a protection board body 1 and a mounting hole 13. The mounting hole 13 is provided on the top of the protection board body 1. Because of the mounting hole 13, it is convenient to install and fix the protection board body 1 to the mounting surface using fasteners. The top of the protection board body 1 has a threaded groove 3. The threaded groove 3 is connected to a threaded block 2. The top of the threaded block 2 is provided with a positioning sleeve. The positioning sleeve 11 is inlaid with a positioning rod 8. The top of the positioning rod 8 is provided with a protective cover 4. The top of the protective cover 4 is inlaid with a transparent plate 5. The outer side of the protective cover 4 is inlaid with a mesh plate 6. By installing the positioning sleeve 11 on the top of the protection board and inlaying the positioning rod 8 inside the positioning sleeve 11, and connecting the protective cover 4 to the top of the positioning rod 8 through a fixing block 7, the protective cover 4 can be removed first, and the positioning rod 8 inside the protective cover 4 can be inlaid in the positioning sleeve 11. In this way, the idle protection board can be protected.

[0029] The protective plate body 1 has a rubber frame 17 on its exterior. The rubber frame 17 is connected to the rubber plate 16 via a pivot. The rubber frame 17 has an anti-slip frame 19 on its exterior. The rubber plate 16 has an anti-slip strip 18 installed on its exterior. The side of the rubber frame 17 has a slot 9. The inside of the rubber plate 16 has an insert 22, which is embedded in the slot 9. By having a rubber frame 17 and a rubber plate 16 on the exterior of the protective plate body 1, an anti-slip frame 19 installed on the exterior of the rubber frame 17, and an anti-slip strip 18 installed on the exterior of the rubber plate 16, the rubber frame 17 is magnetically attached to the exterior of the protective plate body 1. The rubber plate 16 is then rotated via the pivot to connect the rubber plate 16 and the rubber frame 17. Subsequently, the operator can pinch the anti-slip frame 19 and the anti-slip strip 18 from the outside, increasing the friction between the fingers and the exterior of the protective plate body 1, making it more stable when handling.

[0030] The positioning sleeve 11 has a slot 12 inside, and the positioning rod 8 has a block 10 on the outside. The blocks 10 are arranged in a ring shape and are embedded in the slot 12. Because of the blocks 10 and the slot 12, it is convenient to embed the positioning rod 8 in the positioning sleeve 11 for secondary reinforcement.

[0031] The top of the positioning rod 8 is provided with a fixing block 7, and the other side of the fixing block 7 is provided with a protective cover 4. The installation of the fixing block 7 makes it convenient to connect the positioning rod 8 and the protective cover 4.

[0032] The inner side of the rubber frame 17 is provided with a first magnetic absorbing piece 15, and the outer side of the protective plate body 1 is provided with a first metal piece 14. The first magnetic absorbing piece 15 magnetically attracts the first metal piece 14. By installing the first magnetic absorbing piece 15 and the first metal piece 14, the rubber frame 17 can be installed and fixed on the outside of the protective plate body 1.

[0033] The rubber sheet 16 has a second magnetic absorbing piece 21 on its inner side and a second metal sheet 20 on the outer side of the protective plate body 1. The second magnetic absorbing piece 21 magnetically attracts the second metal sheet 20. Because of the second magnetic absorbing piece 21 and the second metal sheet 20, the rubber sheet 16 can be installed and fixed on the outer side of the protective plate body 1.

[0034] The working principle of this lithium battery pack protection board is as follows: Firstly, to protect the outer unit components of the protection board, a threaded groove 3 is opened on the top of the protection board. A threaded block 2 is threadedly connected inside the threaded groove 3. Secondly, a positioning sleeve 11 is installed on the top of the threaded block 2, and a positioning rod 8 is embedded inside the positioning sleeve 11. A protective cover 4 is connected to the top of the positioning rod 8 via a fixing block 7. A transparent plate 5 is embedded on the top of the protective cover 4, and a mesh plate 6 is embedded on its outer side. When the protection board is not in use, the operator first screws on the positioning sleeve 11 to thread the threaded block 2 into the threaded groove 3, thus installing the positioning sleeve 11 on top of the protection board body 1. Then, the protective cover 4 is removed, and the positioning rod 8 inside the protective cover 4 is embedded in the positioning sleeve 11. Simultaneously, the external locking block 10 is embedded inside the locking slot 12. This provides protection for the idle protection board, offering strong protection when not in use. Furthermore, the installed transparent plate 5 allows for timely observation of the internal unit component structure, and the external mesh plate... Plate 6 facilitates ventilation and heat dissipation. However, to facilitate the handling and movement of the relatively small protective plate body 1, a rubber frame 17 and a rubber plate 16 are provided on the outside of the protective plate body 1. The inner side of the rubber frame 17 is provided with a first magnetic absorbing piece 15, and the inner side of the rubber plate 16 is provided with a second magnetic absorbing piece 21. An anti-slip frame 19 is installed on the outside of the rubber frame 17, and an anti-slip strip 18 is installed on the outside of the rubber plate 16. First, the rubber frame 17 is installed on the outside of the protective plate body 1 by magnetic attraction, and then the rubber plate 16 is rotated by a pivot. The rubber plate 16 is used to insert the insert 22 into the slot 9, thus connecting the rubber plate 16 and the rubber frame 17. Subsequently, the staff can pinch the anti-slip frame 19 and anti-slip strip 18 from the outside, which increases the friction between the fingers and the outside of the protective plate body 1, making it more stable when picking it up and preventing it from falling. Finally, after moving it to the appropriate position, the rubber plate 16 is rotated in the opposite direction to remove the insert 22 from the inside of the slot 9, and then the rubber structure is removed from the outside of the protective plate body 1 and placed on a flat surface.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this utility model.
