Various electronic devices, power tools, toys and other products are usually designed with a dedicated battery compartment to fix the position of the batteries, facilitate the installation and replacement of the batteries, and also protect the batteries, prevent them from becoming loose and short-circuiting with other components. The shape, size and design of the battery compartment will vary depending on the type and number of batteries required by different devices.
[0003] Chinese patent application CN202320248958.7 discloses a battery mounting compartment. The key technical point of this invention is that the Bluetooth board integrates a basic circuit set of Bluetooth chip for wireless network communication. The Bluetooth board is located inside the cavity and is electrically connected to the positive and negative connection pieces. The Bluetooth board can receive commands through wireless communication to control the on / off state of the positive and negative terminals. In other words, the installation space, installation structure, and power-on structure of the battery are utilized to complete the installation of the Bluetooth chip and the circuit conduction. Furthermore, people can remotely control the discharge of the battery installed in the cavity and control the power supply to turn the electric toy on or off without additional adjustments to the original circuit board, thus having good applicability.
[0004] Regarding the aforementioned and existing related technologies, the inventor believes that the following defects often exist: Most existing waterproof and dustproof sealed battery compartments for outdoor cameras on the market are single-layer structures with batteries arranged side-by-side. Furthermore, their structures typically involve internal brackets to fix the lithium batteries and protection boards, followed by an outer shell and ultrasonic welding. This type of structure is costly, bulky, and difficult to manufacture and assemble. Additionally, the limited shape of the outer shell results in poor ultrasonic sealing, making it difficult to use in humid outdoor environments, dusty deserts, and underwater conditions. Therefore, to address these issues, a waterproof and dustproof sealed multi-cell battery compartment is proposed. Utility Model Content

[0013] The effect achieved by the above components is that the first spring improves the stability of the insert rod when it is positioned against the protective plate, and at the same time prevents the insert rod from completely detaching from the fixed plate.
[0014] Preferably, a screw is fixedly connected to the lower surface of the fixing plate, and a support plate is threadedly connected to the arc surface of the screw.

[0025] Reference Figure 1-4As shown, this utility model provides a technical solution: a waterproof, dustproof, and sealed multi-cell battery compartment, including a compartment body 1. A side cover plate 2 is ultrasonically welded to one side of the compartment body 1, and a front cover plate 3 is ultrasonically welded to the surface of the compartment body 1. Several battery bodies 12 are installed inside the compartment body 1. Positive and negative nickel plates 9 are connected in series at one end of the battery body 12 by laser welding. A conductive sheet 10 is fixedly connected inside the compartment body 1, and the conductive sheet 10 is electrically connected to one side of the positive and negative nickel plates 9. A protection circuit assembly 11 is installed inside the compartment body 1. A USB female connector 4 is electrically connected to the surface of the protection circuit assembly 11. The surface of the USB female connector 4 is slidably connected to the side cover plate 2. A sealing ring 6 is ultrasonically welded to the surface of the USB female connector 4. The end of the battery body 12 away from the positive and negative nickel plates 9 is laser-welded... A negative nickel plate 7 is attached. A positive nickel plate 8 is laser-welded to the end of the battery body 12 away from the positive and negative nickel plates 9. One side of the negative nickel plate 7 is welded to the protection circuit assembly 11, and one side of the positive nickel plate 8 is welded to the protection circuit assembly 11. Contacts 5 are installed on the surface of the protection circuit assembly 11, and adhesive grooves are formed on the surface of the contacts 5. After the protection circuit assembly 11 is assembled, the exposed part of the USB female connector 4 is sealed and waterproofed by the sealing ring 6 on the end face of the USB female connector 4. After the internal components are assembled and inspected, the side cover 2 and the front cover 3 are sealed ultrasonically, and then the adhesive grooves of the contacts 5 are completely sealed with glue, resulting in a completely sealed square battery compartment that is waterproof and dustproof. When the battery compartment is used alone, it can be charged and discharged through the side USB female connector 4. The battery compartment can be easily inserted into any matching machine's battery slot. Contact point 5 contacts the corresponding battery cell of the machine to achieve charging and discharging. The assembly of the battery compartment semi-finished product is achieved by welding the positive electrode nickel sheet 8 and negative electrode nickel sheet 7 after the assembly of the conductive sheet 10 and the side cover 2. The semi-finished product is inspected and then ultrasonically assembled, which effectively solves the problems of complex internal structure of multi-cell batteries and inconvenient inspection and assembly. At the same time, the flat side cover 2 and front cover 3 are extremely reliable and efficient during ultrasonication. The USB female connector 4 with sealing ring 6 and the contact point 5 with glue groove completely solve the problem of waterproof and dustproof sealing. It can be used well in humid outdoor, dusty desert and underwater environments and protects the internal battery from damage. There are two fixed connections on the surface of the side cover 2. Block 13 has two fixed blocks 13, one close to the other, with a rotating rod 14 fixedly connected to it. A connecting plate 15 is rotatably connected to the arc surface of the rotating rod 14. A protective plate 16 is fixedly connected to one side of the connecting plate 15, and a rubber block 17 is fixedly connected to the side of the protective plate 16 away from the connecting plate 15. The size of the rubber block 17 is adapted to the size of the USB female connector 4. Rotating the protective plate 16 causes the connecting plate 15 to rotate on the arc surface of the rotating rod 14. Simultaneously, the protective plate 16 moves the rubber block 17 until it enters the USB female connector 4. This achieves further protection for the USB female connector 4, preventing dust and impurities from entering the USB female connector 4 during long-term storage or idle periods, thus avoiding large-scale dust blockage.This prevents situations that could affect the normal use of the compartment 1. To improve the protection of the device, a fixing plate 18 is fixedly connected to the surface of the side cover 2. A rod 19 is slidably inserted into the fixing plate 18. A slot is provided on the arc surface of the protective plate 16. When the operator inserts the rubber block 17 into the USB female connector 4, pressing the rod 19 causes it to slide downwards within the fixing plate 18 until it is inserted into the slot of the protective plate 16. This achieves the effect of limiting the position of the protective plate 16, thereby further enhancing the stability of the rubber block 17 inserted into the USB female connector 4 and preventing the rubber block from slipping due to external shaking. 17 detaches from the USB female connector 4, thus affecting the protection of the USB female connector 4. A first spring 20 is fitted onto the arc surface of the insertion rod 19. The two ends of the first spring 20 are fixedly connected to the insertion rod 19 and the fixing plate 18, respectively. When the operator releases the insertion rod 19, the rebound force of the first spring 20 causes the insertion rod 19 to slide within the fixing plate 18 until the insertion rod 19 is inserted into the slot of the protective plate 16. At this time, the first spring 20 improves the stability of the insertion rod 19 when it is limited by the protective plate 16, and also prevents the insertion rod 19 from completely detaching from the fixing plate 18. The lower surface of the fixing plate 18 is fixedly connected to... The screw 21 has a threaded connection to a support plate 22 on its arc-shaped surface. When the operator needs to open the protective plate 16, they pull the insertion rod 19, causing it to slide within the fixed plate 18. The first spring 20 is stretched until the insertion rod 19 disengages from the slot in the protective plate 16. At this point, the support plate 22 rotates, moving along the threaded arc-shaped surface of the screw 21 until it moves below the insertion rod 19. This effectively restricts the downward movement of the insertion rod 19, preventing the protective plate 16 from colliding with the insertion rod 19 during opening or closing, thus avoiding damage to the insertion rod 19. Two torsion springs 23 are fitted onto the arc surface of the rotating rod 14. The two ends of the torsion springs 23 are fixedly connected to the fixing block 13 and the connecting plate 15, respectively. When the operator releases the limiting force of the insertion rod 19 on the protective plate 16, the torque of the torsion springs 23 drives the connecting plate 15 to rotate on the arc surface of the rotating rod 14. Simultaneously, the connecting plate 15 drives the protective plate 16 to move, and the protective plate 16 drives the rubber block 17 to move until it is pulled out of the USB female connector 4. At this point, the torsion springs 23 achieve the effect of automatically releasing the protection of the USB female connector 4, thereby reducing the operator's steps and improving work efficiency.
[0026] The working principle is as follows: After the protection circuit assembly 11 is completed, the exposed part of the USB female connector 4 is sealed and waterproofed through the sealing ring 6 on the end face of the USB female connector 4. After the internal components are assembled and inspected, the side cover 2 and the front cover 3 are ultrasonically sealed, and then the glue groove of the contact 5 is completely sealed with glue, resulting in a completely sealed square battery compartment that is waterproof and dustproof. When the battery compartment is used alone, it can be charged and discharged through the side USB female connector 4. Alternatively, the battery compartment can be easily inserted into any matching machine battery slot, and the contact 5 contacts the corresponding battery cell of the machine to achieve charging and discharging. The assembly of the battery compartment semi-finished product is achieved by welding the positive electrode nickel sheet 8 and negative electrode nickel sheet 7 after the assembly of the conductive sheet 10 and the side cover plate 2. The semi-finished product is inspected and then ultrasonically assembled, which effectively solves the problems of complex internal structure of multi-cell batteries and inconvenience of inspection and assembly. At the same time, the flat side cover plate 2 and front cover plate 3 are extremely reliable and efficient during ultrasonication. The USB female connector 4 with sealing ring 6 and the contact point 5 with glue groove completely solve the problems of waterproof and dustproof sealing. It can be used well in humid outdoor, dusty desert and underwater environments and protects the internal batteries from damage. When the staff needs to protect the inside of the USB female connector 4, press the protective plate 16, and the protective plate 16 drives the connecting plate 15 to rotate. The arc surface of the moving rod 14 rotates, and at the same time, the protective plate 16 drives the rubber block 17 to move until the rubber block 17 enters the USB female connector 4. At this time, the support plate 22 rotates, and the support plate 22 moves in the arc surface of the screw 21 until the support plate 22 disengages from below the insertion rod 19. At this time, the rebound force of the first spring 20 drives the insertion rod 19 to slide in the fixed plate 18 until the insertion rod 19 is inserted into the slot of the protective plate 16. At this time, the USB female connector 4 is further protected, avoiding the situation where dust and impurities enter the USB female connector 4 after long-term storage or idleness, causing the USB female connector 4 to be blocked by a large amount of dust, thus affecting the normal use of the compartment 1, and improving the protection of the device.
