As a key component to ensure the safe and stable operation of the battery, the performance of the lithium-ion battery protection board is directly related to the working status of the geophysical instrument.

[0003] Traditional lithium-ion battery protection boards for geophysical instruments suffer from the following problems in structural design and functional implementation: Firstly, the fixing method between the circuit board and the battery module is complex, often requiring simultaneous fixing of the battery module and circuit board. This not only increases installation difficulty but also makes disassembly cumbersome during later inspection and maintenance, consuming significant time and manpower, severely impacting work efficiency. Secondly, traditional protection boards mostly use terminal blocks for wire connections. In practice, wiring requires soldering, which is not only complex and technically demanding but also extremely inconvenient for disassembly and replacement in case of circuit problems. Furthermore, the soldering process carries potential risks such as cold solder joints and desoldering, affecting circuit stability and safety.

[0004] With the rapid development of geophysical exploration technology and the increasing complexity of application scenarios, higher requirements have been placed on the convenience, stability and reliability of lithium-ion battery protection boards. Therefore, developing a lithium-ion battery protection board for geophysical instruments that is easy to install and maintain and simplifies wiring operations has become an urgent problem to be solved. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] This utility model embodiment provides a battery protection board, which is applied to scenarios where lithium-ion batteries are protected during use. This embodiment improves the structure of the battery protection board, giving it the advantages of easy circuit board mounting and simple, stable wiring. Specifically, taking the protection of lithium-ion batteries as an example, as a preferred solution in this embodiment, the battery protection board is specifically a lithium-ion battery protection board for geophysical instruments, which enables stable and quick installation of the circuit board and facilitates wiring.

[0027] Example: Referring to Figures 1 to 5, this utility model provides a lithium-ion battery protection board for geophysical instruments. This battery protection board is mainly used in scenarios where lithium-ion batteries are protected during use.

[0028] The lithium-ion battery protection board for the geophysical instrument includes a positioning mechanism 3, a circuit board 4, and multiple wiring mechanisms 5. The positioning mechanism 3 includes a positioning base 301 and four locking blocks 302, with the four locking blocks 302 fixedly installed at the four corners of the positioning base 301. The circuit board 4 is snapped between the positioning base 301 and the four locking blocks 302. The wiring mechanism 5 includes a conductive sheet 501, a protective shell 502, and a spring 503. The conductive sheet 501 is fixedly installed on the outer wall of the circuit board 4, the protective shell 502 is fixedly connected to the outer surface of the conductive sheet 501, and one end of the spring 503 is fixedly connected to the outer wall of the conductive sheet 501 and located on the inner side wall of the protective shell 502.

[0029] The positioning base 301 serves as the mounting foundation for the circuit board 4, providing a stable mounting position and ensuring its fixed position within the protection board. This prevents vibration or displacement from affecting its normal operation, thus improving the overall stability of the protection board. Four locking blocks 302 are installed at the four corners of the outer surface of the positioning base 301 to engage the circuit board 4, fixing it to the outer wall of the positioning base 301. Compared to the traditional method of simultaneously fixing the battery module 1 and the circuit board 4, this locking method simplifies installation and disassembly, facilitating maintenance and repair of the circuit board 4 and improving work efficiency. The circuit board 4 is the core component of the entire protection board, housing various electronic components and circuits to provide protection for the lithium-ion battery, such as overcharge protection, over-discharge protection, and short-circuit protection. This ensures the lithium-ion battery operates within a safe voltage and current range, extending its lifespan and improving the performance of geophysical instruments. To ensure safety and stability when using the battery, the conductive sheet 501 is fixedly installed on the outer wall of the circuit board 4, serving as a conductive connection between the wires and the circuit board 4 to achieve current transmission and reliably connect the wires to the circuit board 4, ensuring circuit continuity and providing a stable current path for battery charging and discharging operations. The protective shell 502 provides protection for the wire connectors and conductive sheet 501, preventing the entry of external dust, moisture, and other impurities. At the same time, it provides installation space for components such as the spring 503, protecting the wire connectors and conductive sheet 501 from external environmental influences, extending their service life, and improving the reliability of the circuit connection. The spring 503 cooperates with the protective shell 502 to fully clamp and fix the wire connector after the wire is inserted into the protective shell 502, achieving a reliable connection of the wire without welding, facilitating wiring and disassembly, reducing operational difficulty, and avoiding the risks of poor soldering and desoldering caused by welding, thus improving the stability and safety of the circuit.

[0030] In this embodiment, a battery module 1 is provided on one side of the positioning mechanism 3. An insulating protective sleeve 2 is fitted onto the outer surface of the battery module 1. The battery module 1 serves as the power source for the geophysical instrument, providing electrical energy to ensure that the geophysical instrument can work normally and meet the power requirements of geophysical operations. The insulating protective sleeve 2 is fitted onto the outer surface of the battery, playing a role in insulation and protection, preventing leakage of the battery module 1, avoiding safety accidents caused by leakage, and protecting the battery module 1 from external physical damage, thus extending the service life of the battery.

[0031] In the above embodiment, as shown in FIG2, the positioning mechanism 3 further includes a positioning sleeve 303 and a limiting block 304. The positioning sleeve 303 is fixedly connected to the four locking blocks 302 respectively. The limiting block 304 is rotatably connected to the outer wall of the positioning sleeve 303 through a rotating shaft. The positioning sleeve 303 is fixedly connected to the outer surface of the four locking blocks 302 respectively, providing a support structure for the installation and rotation of the limiting block 304, ensuring that the limiting block 304 can be stably installed on the locking blocks 302 and can rotate flexibly, thereby realizing the limiting function of other components. The limiting block 304 is rotatably connected to the outer wall of the positioning sleeve 303 through a rotating shaft, which can limit the mounting plate 701 of the heat dissipation mechanism 7, ensuring the accuracy and stability of the installation position of the heat dissipation mechanism 7, preventing the heat dissipation mechanism 7 from shifting or loosening, and ensuring the normal functioning of the heat dissipation function.

[0032] In the above embodiment, as shown in FIG5, the wiring mechanism 5 further includes two push rods 504 and two guide holes 506. The two guide holes 506 are respectively opened on both sides of the protective shell 502. The two push rods 504 are slidably connected in the two guide holes 506. The push rods 504 are slidably connected to the inner sidewalls of the guide holes 506 on both sides of the outer surface of the protective shell 502. The push rods 504 can be pushed to drive the push plate 505 to move, providing power transmission for the movement of the spring 503, which facilitates the operator to clamp or release the wire connector. The guide holes 506 are opened on both sides of the outer surface of the protective shell 502 to provide guidance for the sliding of the push rods 504, ensuring that the push rods 504 can slide in a predetermined direction, ensuring that the movement direction of the spring 503 is accurate, thereby realizing the effective clamping of the wire connector.

[0033] In the above embodiment, the wiring mechanism 5 further includes a push plate 505. The two sides of the bottom of the push plate 505 are fixedly connected to the ends of two push rods 504 respectively. The push plate 505 is used to push the spring 503 to move, and transmit the pushing force of the push rod 504 to the spring 503, so as to realize the clamping and releasing action of the spring 503 on the wire connector, making the wiring operation more convenient.

[0034] In the above embodiment, referring to Figure 4, a silicone grease patch 6 is attached and fixed on the circuit board 4. The silicone grease patch 6 has a groove corresponding to the protective shell 502. The silicone grease patch 6 is attached and fixed on the outer surface of the circuit board 4. The groove corresponding to the protective shell 502 on its outer surface has good thermal conductivity and transfers the heat generated by the circuit board 4 to the heat dissipation mechanism 7, which plays a role in heat dissipation and buffering. At the same time, the design of the groove avoids affecting the installation of the protective shell 502.

[0035] The thermal paste 6 is provided with a heat dissipation mechanism 7, which includes a mounting plate 701. The bottom of the mounting plate 701 is attached and fixed to the outer surface of the thermal paste 6, providing mounting support for the heat sink 702 and tightly connecting the heat sink 702 to the thermal paste 6. This ensures that heat can be transferred from the circuit board 4 to the heat sink 702 through the thermal paste 6, achieving effective heat dissipation.

[0036] In the above embodiment, the heat dissipation mechanism 7 further includes a plurality of heat sinks 702, which are all fixedly connected to the mounting plate 701. The limiting block 304 is located on the outside of the mounting plate 701, and its inner surface is in contact with the outer surface of the mounting plate 701. It is fixedly connected to the outer surface of the mounting plate 701 by the heat sinks 702. By increasing the heat dissipation area, the heat dissipation is accelerated, the temperature of the circuit board 4 is reduced, the circuit board 4 is ensured to work in a suitable temperature environment, the performance and stability of the circuit board 4 are improved, and its service life is extended.

[0037] In use, insert the circuit board 4 between the clips 302 to fix the circuit board 4, then stick the silicone grease 6 to the surface of the circuit board 4, and then stick the mounting plate 701 to fix it. Then rotate the limiting block 304 to clamp the outer wall of the mounting plate 701, thus completing the installation and fixing of the device. Pressing down the push plate 505 will drive the push rod 504 to squeeze and deform the spring 503, insert the wires to be connected into the protective shell 502, and clamp and fix them with the elasticity of the spring 503. Releasing the push plate 505 completes the connection of the circuit. During use, the heat sink 702 dissipates the heat generated by the circuit board 4 in time.
