Description

Technical Field

[0001] This utility model belongs to the technical field of magnetic therapy equipment accessories, specifically relating to a battery assembly device. Background Technology

[0002] Magnetic therapy equipment is an electronic device that uses electromagnetic fields for therapeutic purposes. Typically, the magnetic therapy equipment is placed at the target location and turned on to achieve therapeutic effects through magnetic fields, vibrations, etc.

[0003] Existing magnetic therapy devices typically include a magnetic field generator and a battery pack, which provides power to the magnetic field generator and other electrical components. In existing magnetic therapy devices, the battery pack is directly plugged into the housing, secured using pins and sockets. This method of securing the battery pack to the housing results in a weak connection, making it prone to detachment during use and potentially damaging the magnetic therapy device. Utility Model Content

[0004] This utility model provides a battery assembly device, which aims to solve the problems of unreasonable battery component installation structure and low connection strength between battery component and shell in the prior art magnetic therapy equipment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A battery assembly device includes a housing, a top cover disposed on the housing, and a connector disposed on one end of the housing away from the top cover;

[0007] The housing contains a battery cell assembly, a power supply plate, and a thin-film panel. The thin-film panel is connected to the battery cell assembly via the power supply plate.

[0008] One side of the housing is provided with a latch for fixing the housing to other equipment.

[0009] A further improved solution: the angle between the latch and the side of the housing where the latch is located is 60° to 80°.

[0010] Based on the above technical solution, the 60° to 80° angle design makes the connection between the latch and the housing more stable, better resisting external shaking or movement, thereby improving the stability of the entire magnetic therapy device. Within this angle range, the latch can more effectively distribute and bear the weight from the battery assembly or other components, reducing the risk of structural deformation or damage caused by uneven load distribution. Stable connection and optimized load-bearing capacity can reduce wear and tear and malfunctions during use, thus extending the overall lifespan and durability of the device. While the angle design primarily affects stability and load-bearing capacity, a reasonable angle may also make installation and disassembly of the latch more convenient and quick, improving the user experience.

[0011] A further improved solution: the angle between the latch and the side of the housing where the latch is located is 70°.

[0012] Based on the above technical solution: the 70° angle provides a connection angle between the latch and the housing that is neither too steep nor too gentle. This design helps to more effectively distribute and bear external forces when the device is subjected to them, thereby maintaining the overall stability of the device. Through the designed 70° angle, the latch can more evenly bear the weight from the battery pack or other components, reducing the risk of structural deformation or damage caused by uneven load distribution and extending the device's service life. The 70° angle design also helps to enhance the structural strength of the connection between the latch and the housing, allowing the entire device to better maintain its integrity and functionality when subjected to impacts or vibrations.

[0013] A further improvement: The housing is provided with a bayonet for engaging the connector.

[0014] Based on the above technical solutions: the bayonet design ensures a more secure fixation of the connector to the housing, reducing the risk of equipment failure due to connector loosening or detachment. The bayonet design simplifies the connector assembly process, allowing operators to install connectors faster and more accurately, thereby improving production efficiency. The bayonet design allows for a compact arrangement on the housing, helping to optimize internal space utilization and making the entire device more compact and portable. A stable connector fixing method reduces the failure rate during equipment use, improving overall reliability and durability. The bayonet design also makes connector disassembly and replacement easier, facilitating equipment maintenance and upgrades.

[0015] A further improvement: The housing is also provided with a groove to prevent the housing from being inserted in the wrong direction when it is plugged into other devices, and the groove passes through one end of the housing.

[0016] Based on the above technical solution: the groove design ensures that the housing can only be inserted in the correct direction when connected to other devices, effectively preventing damage or malfunction caused by reverse insertion. The groove guides the operator, allowing for faster alignment and improved insertion efficiency. The anti-reverse insertion design reduces equipment malfunctions and safety hazards caused by incorrect insertion, enhancing overall equipment safety. Users no longer need to worry about reverse insertion, improving the user experience. If equipment replacement or repair is required, the correct insertion direction ensures faster and more accurate operation, facilitating equipment maintenance and replacement.

[0017] A further improved solution: the groove extends through the end of the housing away from the top cover.

[0018] Based on the above technical solution: the groove penetrates the end of the shell furthest from the top cover, meaning that during insertion, this groove acts as a more obvious guide, helping operators quickly find the correct insertion direction, especially in situations with poor visibility or limited operating space. This design can greatly improve the accuracy and efficiency of insertion. Although the primary function of the groove is guidance, the design of penetrating the shell also enhances the structural stability of the shell to a certain extent. Because the groove forms a reinforcing rib on the shell, it helps resist external forces and reduces the risk of deformation or damage. From a production and assembly perspective, the groove design penetrating the shell makes mold processing and shell assembly processes simpler and more efficient. Because the groove is part of the shell, it can be formed in one step during mold processing, reducing subsequent processing steps.

[0019] A further improved solution: the groove and the latch are respectively disposed on opposite sides of the housing.

[0020] Based on the above technical solution: by placing the grooves and latches on opposite sides of the housing, the space within the housing can be utilized more efficiently, making the entire device more compact and portable. The opposing arrangement of the grooves and latches allows operators to more easily insert and secure connectors, improving work efficiency and user experience. The grooves and latches, located on opposite sides of the housing, form a symmetrical support structure, which helps enhance the overall stability and load-bearing capacity of the housing.

[0021] A further improved solution: The housing is provided with a cavity for accommodating the battery cell assembly, and a silicone rubber layer is provided between the battery cell assembly and the cavity.

[0022] Based on the above technical solution: the silicone rubber layer possesses excellent elasticity and cushioning properties. When the equipment is subjected to external impacts or vibrations, the silicone rubber layer can absorb and disperse this energy, reducing damage to the battery cell assembly and thus protecting its integrity and functionality. The silicone rubber layer also has certain thermal insulation properties, which can, to some extent, prevent the influence of external temperatures on the battery cell assembly, keeping it within a suitable operating temperature range and improving battery life and performance. The silicone rubber layer can form a sealed barrier, preventing moisture, dust, and other impurities from entering the containment cavity, thereby protecting the battery cell assembly from moisture and contamination and ensuring its normal operation.

[0023] A further improved solution: The upper cover is provided with a through hole for the flexible flat cable of the thin film panel to pass through, the power board is fixed to the upper cover by screws, the side wall of the receiving cavity is provided with a protrusion, and the upper cover is provided with a recess to prevent the upper cover from being installed backwards and to cooperate with the protrusion.

[0024] Based on the above technical solution: the through holes in the top cover provide a channel for the flexible flat cable of the thin-film panel to pass through, allowing the flexible flat cable to be easily connected to the internal circuitry of the device, simplifying the connection process and improving assembly efficiency. Fixing the power board to the top cover with screws ensures the stability of the power board inside the device, reducing the risk of circuit failure due to shaking or movement, and improving the reliability and durability of the device. The reasonable through-hole and screw fixing design allows for a more compact arrangement of the internal circuitry and components, optimizing the spatial layout of the device and making the entire device more compact and portable.

[0025] A further improved solution: The thin film panel is adhered to the surface of the upper cover, and the thin film panel is connected to the power board via the flexible flat cable.

[0026] Based on the above technical solution: fixing the film panel to the surface of the top cover by adhesive bonding ensures the stability of the film panel during equipment use, reducing operational inconvenience or malfunction risks caused by shaking or movement. The flexible and bendable flat cable allows for easy connection between the film panel and the power board, adapting to different internal spatial layouts and connection requirements. Simultaneously, the flexible flat cable also reduces the risk of loosening or breakage due to vibration or impact.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention utilizes a locking mechanism to securely fasten the housing to the housings of other devices, improving the overall stability of the magnetic therapy equipment and reducing the risk of battery components detaching due to device shaking or movement. By rationally arranging components such as the battery cell pack, power supply plate, and thin-film panel within the housing, internal space utilization is optimized, improving the overall performance and reliability of the equipment.

[0029] Because the battery pack is more securely connected to the casing, users can use the device with greater peace of mind, without worrying about damage or interruption caused by battery pack detachment. The stable connection and optimized internal layout reduce internal wear and tear and malfunctions, thus extending the overall lifespan of the device. The robust connection and optimized design also improve device safety, reducing safety hazards caused by battery pack detachment or other internal failures. Attached Figure Description
