Description

Technical Field

[0001] This utility model relates to the field of battery mounting structure technology, and in particular to a quick-locking device for button-type battery cells. Background Technology

[0002] As electronic devices continue to evolve towards miniaturization, lightweighting, and portability, button cells, with their advantages of compact structure, high energy density, low self-discharge rate, and strong designability, have been widely used in smart wearable devices, wireless sensor nodes, handheld tools, and other low-power electronic products, becoming an efficient and convenient energy storage solution in current battery-powered systems.

[0003] In practical applications, traditional button cell fixing methods mainly include screw fixing and direct embedding. While screw fixing can improve the installation stability of the cell to some extent, its assembly process is cumbersome, inefficient, and inconvenient to disassemble, making it difficult to replace quickly. Direct embedding simplifies the assembly process, but during use, especially under conditions of vibration or impact, the cell is prone to loosening or even falling off, leading to poor contact and affecting the normal operation and reliability of the equipment.

[0004] Therefore, there is an urgent need to provide a quick-locking device for button-type battery cells, which should be able to achieve quick installation and disassembly while effectively improving the stability of the battery cells in the battery slot. Utility Model Content

[0005] In order to overcome the shortcomings of existing button cell installation methods such as screw fixing or direct embedding, which have low assembly efficiency, inconvenient disassembly, and loose installation, this utility model provides a quick locking device for button cells.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a snap-on battery cell quick-locking device, comprising a housing and a battery cell body. The battery cell body is fitted with the housing, and a first rubber block is provided on the corner of the housing. Symmetrically distributed mounting slots are provided on both sides of the housing, and a moving rod is slidably disposed inside each mounting slot. A limit block is provided at one end of the moving rod, and a second rubber block is provided on the side of the limit block facing the battery slot. A spring is connected between the other end of the moving rod and the inner wall of the mounting slot.

[0007] Preferably, the top and bottom of the housing are provided with multiple ventilation slots.

[0008] Preferably, the top of the outer casing is fixed with symmetrically distributed connecting plates by screws, and the connecting plates are all provided with symmetrically distributed heat-conducting plates, which are in close contact with the top of the outer casing.

[0009] Preferably, the bottom of the outer casing is provided with a mounting shell, and a fan is installed inside the mounting shell.

[0010] Preferably, a dustproof net is provided on the outside of the mounting housing.

[0011] Preferably, U-shaped protective plates are snapped onto both sides and both ends of the outer casing.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By setting first rubber blocks at the four corners of the outer shell and symmetrically arranging a locking structure including a moving rod, a limiting block and a second rubber block on both sides, the battery cell applies multi-point support and clamping force to the outer shell during the insertion of the battery cell into the battery slot, thereby realizing the automatic locking function. This structure does not require additional tools or complex operations during assembly, which significantly improves the installation efficiency and the convenience of subsequent maintenance. At the same time, it can also prevent the battery cell from loosening or falling off due to impact or vibration, thereby ensuring the stability of electrical connection and the reliability of equipment operation.

[0013] 2. With ventilation slots at the top and bottom of the casing, a forced convection cooling method formed by a fan, and an efficient heat conduction path formed by a heat-conducting plate, the heat generated during the operation of the battery cell can be dissipated in a timely manner, avoiding performance degradation or safety hazards caused by local overheating and extending the service life of the battery cell.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figures 1-3 A quick-locking device for a snap-on battery cell includes a housing 1 and a battery cell body 2. The housing 1 is fitted over the battery cell body 2. Each of the four corners of the housing 1 has a first rubber block 3 for initial positioning and buffering during battery cell insertion into the battery slot. The housing 1 has two symmetrically distributed mounting slots on its left and right sides. A sliding rod 4 is slidably mounted inside each mounting slot. A limit block 5 is mounted at one end of each sliding rod 4. A second rubber block 7 is mounted on the side of the limit block 5 facing the battery slot to increase friction between the limit block 5 and the inner wall of the battery slot. The moving rod 4 is connected to the inner wall of the mounting groove by a spring 6, which provides a restoring force to the moving rod 4. When no external force is applied, the spring 6 is in a naturally extended state, keeping the limiting block 5 in an outward extended state. The left and right sides and the front and rear ends of the outer shell 1 are all fitted with U-shaped protective plates 15. The U-shaped protective plates 15 are detachably fixed to the corresponding parts of the outer shell 1 by a buckle structure and are made of plastic with a certain strength and elasticity, which can effectively resist external impact, compression and other mechanical stresses.

[0022] During actual installation, the battery cell body 2 is inserted into the battery slot. During this process, the second rubber block 7 on the limiting block 5 first contacts and is squeezed against the side wall of the battery slot, pushing the moving rod 4 to slide into the mounting slot. The spring 6 is then compressed and stores energy. When the battery cell is fully inserted into the predetermined position, the limiting block 5 quickly resets under the action of the spring 6's restoring force, causing the second rubber block 7 to adhere tightly to the inner wall of the battery slot, forming a stable frictional locking state. At this time, the first rubber blocks 3 at the four corners of the outer casing 1 and the second rubber blocks 7 on both sides work together to apply multi-point support and clamping force to the outer casing 1, effectively preventing the battery cell from shifting or falling off due to vibration, impact, or external disturbance during use. This ensures the electrical connection stability and structural reliability between the battery cell and the battery slot. In addition, when disassembling the battery cell, only a certain external force needs to be applied to pull the battery cell out of the battery slot. The unlocking action can be completed without additional operation, realizing quick replacement and maintenance.

[0023] Example 2: Based on Example 1, please refer to... Figure 4The top and bottom of the outer shell 1 are provided with three ventilation slots 8 to provide air circulation paths and promote the effective dissipation of internal heat. The top of the outer shell 1 is fixed with two connecting plates 9 symmetrically distributed front and back by screws 11. The connecting plates 9 are jointly provided with two heat-conducting plates 10 symmetrically distributed left and right. The heat-conducting plates 10 are tightly attached to the top of the outer shell 1. The heat-conducting plates 10 are made of high thermal conductivity material to achieve efficient heat conduction.

[0024] Please see Figure 5 The bottom of the outer shell 1 is provided with a mounting shell 12, a fan 13 is installed inside the mounting shell 12, and a dustproof net 14 is provided on the outside of the mounting shell 12 to prevent external dust and impurities from entering the interior of the outer shell 1.

[0025] When the battery cell is working, the fan 13 can be turned on. Outside cold air is drawn in through the bottom ventilation slot 8 and passes through the surface of the battery cell and its surrounding area. After absorbing heat, it is discharged through the top ventilation slot 8. At the same time, since the heat conduction plate 10 is in direct contact with the top of the outer casing 1 and is in close contact with it, it can efficiently diffuse some of the heat transferred from the battery cell to the outer casing 1 to the surface of the heat conduction plate 10, thereby accelerating the rate of heat dissipation to the outside environment and ensuring that the battery cell is maintained within a suitable operating temperature range. This effectively avoids performance degradation and safety risks caused by overheating.
