Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a lithium battery protection board that is easy to install and remove. Background Technology

[0002] The lithium battery protection board provides charging and discharging protection for series-connected lithium battery packs. When fully charged, it ensures that the voltage difference between individual cells is less than a set value, achieving equal charging of all cells in the battery pack and effectively improving the charging effect under series charging. At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature conditions of each individual cell in the battery pack, protecting and extending the battery's lifespan.

[0003] According to a search, Chinese patent document CN218648012U discloses an assembled lithium battery protection board. When the lithium battery protection board body is constrained by a limiting mechanism, the elastic arc-shaped heat-conducting plate undergoes elastic deformation. Under the action of the elastic restoring force of the arc-shaped heat-conducting plate, the base plate can stably and tightly contact the upper surface of the lithium battery body, thereby improving the thermal stability between the base plate and the lithium battery body and enhancing the reliability of the device. However, during use, although the positioning pins can limit the lithium battery protection board body, it is prone to movement when subjected to pressure, leading to detachment, loss of protective effect, and poor fixation. Furthermore, during use, when subjected to external impact, the protection board is easily deformed and damaged without cushioning, resulting in a reduced service life. Utility Model Content

Moreover, during the lifting and buffering process of the protective plate body, the bottom side of the protective plate body is squeezed against the rubber column, thereby avoiding damage to the lithium battery body and improving the dissipation of external force. Furthermore, when the protective plate body is reset, the buffer rubber pad can provide buffer protection and reduce wear, thereby avoiding damage to the protective plate body and improving the overall service life and protective effect of the protective plate body.

[0020] 2. When the protection plate body needs to be installed, the fixing sleeve is first positioned and engaged with the lithium battery body.

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.

[0030] Example 1:

[0031] like Figure 1-7 As shown, the present invention provides a lithium battery protection board that is easy to assemble and disassemble, including a lithium battery body 1. A fixing sleeve 2 is installed on the outer side of the upper end of the lithium battery body 1 by bolts. A mounting base 3 is fixedly installed on the top side of the fixing sleeve 2. A groove 4 is opened on the opposite side of the mounting base 3. A positioning plate 5 is movably installed on the inner side of the groove 4. A protection board body 6 is installed on the opposite side of the positioning plate 5 by snap-fit. A stop block 7 is installed on the front side of the mounting base 3 by bolts.

[0032] Specifically, a positioning post 101 is fixedly installed on the left side of the lithium battery body 1. A connecting screw hole 102 is provided on the left side of the positioning post 101. The positioning post 101 and the connecting screw hole 102 are arranged as a set, and a total of two sets are provided. The positioning post 101 and the connecting screw hole 102 are located at the upper ends of the left and right sides of the lithium battery body 1, respectively. The advantage is that the positioning post 101 facilitates positioning and installation when installing the fixing sleeve 2, improving the ease of installation. Furthermore, the connecting screw hole 102 facilitates bolt connection, thereby connecting and fixing the fixing sleeve 2.

[0033] Specifically, the bottom side of the fixing sleeve 2 has a positioning groove 201, the size and shape of which matches the positioning post 101. The top side of the fixing sleeve 2 has a through groove 202, and the left side of the positioning groove 201 has a fixing hole 203. The positioning groove 201 and the fixing hole 203 form a set, and there are two sets in total. A rubber post 204 is fixedly installed on the top side of the fixing sleeve 2. The advantage is that by positioning and engaging the positioning groove 201 on the bottom side of the fixing sleeve 2 with the positioning post 101, and then using a bolt to pass through the fixing hole 203 and connect and fix it with the connecting screw hole 102, the fixing sleeve 2 can be removed by rotating the bolt in the opposite direction when disassembly is required.

[0034] Specifically, movable grooves 401 are respectively provided on the top and bottom sides of the inner side of the groove 4. A positioning plate 5 is movably installed on the inner side of the movable groove 401, and several sets of equidistant buffer springs are fixedly installed between the positioning plate 5 and the movable groove 401. A base groove 301 and a fixing screw hole 302 are respectively provided on the front side of the mounting base 3. The advantage is that the positioning plate 5 is driven to move up and down inside the movable groove 401 by the protective plate body 6, which facilitates the reset and dissipation of external force by the buffer springs, thereby improving the protective effect. In addition, during the assembly process, the protective plate body 6 is clamped and fixed by the positioning plate 5 and the buffer springs.

[0035] Example 2:

[0036] like Figure 1-7 As an improvement on the previous embodiment, specifically, protective frames 601 are fixedly installed at the left and right ends of the top side of the protective plate body 6. The protective frames 601 have an L-shaped structure, and buffer rubber pads 602 are fixedly installed at the front and rear ends of the top side of the protective frame 601. The rear side of the protective plate body 6 has a conical structure. The advantage is that by adding the L-shaped protective frame 601, it is beneficial to distribute the pressure through the buffer rubber pads 602 when the protective frame 601 is subjected to pressure, and to reduce the friction between the protective plate body 6 and other components after it resets, thereby improving the overall service life of the protective plate body 6.

[0037] Specifically, two base plates 701 are fixedly installed on the rear side of the stop block 7. The size and shape of the base plates 701 match the base groove 301, and the front side of the stop block 7 has connecting holes 702, which correspond one-to-one with the fixing screw holes 302. A total of two stop blocks 7 are provided. The advantage is that by positioning and engaging the base plates 701 on the rear side of the stop block 7 with the base groove 301, it is convenient to use bolts for fixing, thereby preventing the protective plate body 6 from falling off. When disassembling, turning the bolts to remove the stop block 7 makes it easy to pull out the protective plate body 6, making disassembly and assembly convenient and quick.

[0038] In use, when the protection plate body 6 is subjected to external pressure, the positioning plate 5 moves up and down inside the movable groove 401 via the protection plate body 6. This facilitates the reset of the protection plate body 6 and the dissipation of external force through the buffer spring, thereby improving the protective effect. Furthermore, during the lifting and lowering buffering process of the protection plate body 6, the bottom side of the protection plate body 6 is pressed against the rubber pillar 204, thus preventing damage to the lithium battery body 1 while improving the dissipation of external force. Moreover, when the protection plate body 6 resets, the buffer rubber pad 602 provides buffer protection and reduces wear, thereby preventing damage to the protection plate body 6 and improving the overall protection effect. Regarding the overall service life and protective effect of the body 6, when it is necessary to install the protective plate body 6, firstly, the fixing sleeve 2 is positioned and engaged with the lithium battery body 1, and then the bolt is passed through the fixing hole 203 and connected and fixed with the connecting screw hole 102. Then, the tapered structure of the protective plate body 6 is pressed and engaged with the two sets of positioning plates 5. At the same time, the protective plate body 6 is clamped and fixed under the action of the positioning plates 5 and the buffer spring. Then, the base plate 701 on the back side of the stop block 7 is positioned and engaged with the base groove 301, which is convenient for fixing with bolts. When disassembling, the bolt is turned to remove the stop block 7 and the protective plate body 6 can be pulled out easily. The disassembly and assembly are convenient and quick.
