[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-5 The utility model provides a three-layer detachable battery compartment, including a first compartment body 1 and a second compartment body 2, one side of the first compartment body 1 and one side of the second compartment body 2 are fixedly connected with a strip plastic cover 3, the other side of the first compartment body 1 and the other side of the second compartment body 2 are fixedly connected with a square plastic cover 4, one side of the first compartment body 1 and one side of the second compartment body 2 are fixedly connected with a PCB assembly 5, the other side of the first compartment body 1 and the other side of the second compartment body 2 are fixedly connected with positive and negative battery cells 6 and internal battery cells 7, the inner sides of the two PCB assemblies 5 are fixedly connected with positive battery cells 8 and negative battery cells 9, multiple batteries 10 are installed inside the first compartment body 1 and the second compartment body 2, the top of the first compartment body 1 is fixedly connected with a rotating shaft 11, the bottom of the second compartment body 2 is provided with a pipe sleeve 12 corresponding to the rotating shaft 11, the top of the second compartment body 2 is fixedly connected with a buckle 13 near the outer side, and the outer side of the first compartment body 1 and the outer side of the second compartment body 2 are fixedly connected with battery cell contacts 14.

[0023] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the first bin body 1 and the second bin body 2 are rotationally symmetrical in design. The rotationally symmetrical design makes the two bin bodies interchangeable in structure, simplifies the manufacturing and assembly process, and is easy to produce. This design is convenient for users to disassemble or install the battery compartment, which improves the convenience of operation, especially in space-constrained environments. At the same time, the symmetrical design helps to evenly distribute the weight of the bin bodies, making the device more stable during use and reducing tilting caused by uneven center of gravity. Since the two bin bodies have the same structure, users can be more convenient when maintaining, replacing and upgrading. The symmetrical visual effect enhances the beauty of the product appearance, makes the device more attractive to users, and forms consistency in design.

[0024] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it is worth mentioning that the strip plastic cover 3 and the square plastic cover 4 are both installed by ultrasonic welding. Ultrasonic welding can form strong and durable welding joints to ensure that the strip plastic cover 3 and the square plastic cover 4 are firmly combined with the battery compartment structure, greatly reducing loosening caused by vibration or collision. The welding process can achieve a better sealing effect under the action of high-frequency sound waves, preventing liquid, dust and external impurities from entering the battery compartment, thereby enhancing the protection performance of the battery compartment. At the same time, ultrasonic welding can shorten the assembly time and improve the overall efficiency of the production line. The welded connection makes the product appearance smooth, without exposed connectors or glue, thereby improving the aesthetics of the entire machine. The overall strength and consistency of the welding joint are high, thereby improving the reliability of the product during use and reducing the failure rate.

[0025] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that multiple battery slots corresponding to the batteries 10 are provided inside the first compartment 1 and the second compartment 2, and each compartment has an independent battery slot, so that users can easily replace the batteries 10 without disassembling the entire battery compartment, thereby improving the convenience of use. If the battery 10 in one battery slot fails or is low on power, the battery 10 in the other compartment can still provide power, enhancing the reliability and continuous operation capability of the equipment. The design of multiple battery slots allows the weight of the battery 10 to be more evenly distributed throughout the compartment, avoiding tilting or instability of the equipment due to uneven weight. At the same time, the corresponding slots can effectively prevent the battery 10 from moving and colliding during use, reducing the risk of battery damage and short circuit. Each battery slot is independently set, which is convenient for users to inspect and maintain the battery 10 individually, and to promptly detect and replace problematic batteries 10, thereby improving the safety of the equipment.

[0026] Further as Figure 3 As shown, it is worth mentioning that the sleeve 12 is rotatably connected to the outer wall of the shaft 11, and the sleeve 12 can rotate freely on the shaft 11. This design makes the battery compartment more flexible in operation, and the user can adjust the battery compartment as needed for easy access or removal. The design of the rotating connection makes it easier to open and close the battery compartment. The user only needs to rotate the sleeve 12 without complicated disassembly or tightening operations, which improves the user experience. The rotating connection can effectively reduce the friction between the structures and reduce the wear caused by frequent operation, thereby extending the service life of the components. This connection method can usually provide a neater and smoother appearance design, making the battery compartment look more integrated and beautiful, increasing the attractiveness of the product.

[0027] Further as Figure 3As shown, it is worth mentioning that a snap-on column corresponding to the buckle 13 is provided inside the first compartment body 1. The snap-on column provides a reliable fixing point to ensure the stability of the battery compartment during use and prevent loosening due to vibration or collision. The design of the buckle 13 and the snap-on column is very simple. Users can assemble and disassemble by simply snapping in or pulling out without using additional tools, which improves the user's operating experience. Through the snap-on design, the components can be more tightly combined to help improve the overall sealing, effectively prevent dust and moisture from entering the battery compartment, protect the battery and electronic components, and at the same time ensure that the battery compartment does not have to worry about accidental falling off or loosening during operation, thereby improving safety during use.

[0028] This solution has the following working process: in actual use, the buckle 13 on the side of the second compartment 2 can be opened, and the first compartment 1 and the second compartment 2 can be opened by rotating the shaft 11, so that the middle layer battery 10 can be installed conveniently and quickly. Conversely, after the batteries 9 are installed in the battery slots inside the two battery compartments, the first compartment 1 and the second compartment 2 can be easily fastened together by the buckle 13. The buckle 13 can firmly lock the two battery compartments and will not loosen or fall apart. The battery compartment after fastening is a rectangular compartment with a small space volume. The battery compartment is then inserted into the battery compartment slot of the machine body, and the battery cell contacts 14 contact the positive and negative poles of the machine body to discharge, and it can be powered on and used.

[0029] In summary: by setting a rotationally symmetrical first bin body 1 and a second bin body 2, after the batteries are installed in the internal battery slots of the two bin bodies, the two bin bodies can be easily fastened together by means of a snap 13, and the snap 13 can firmly lock the two battery bins and will not loosen or fall apart. The battery bin after fastening is in the form of a rectangular bin body with a small space volume. The simplified structure and detachable design are convenient for users to clean and maintain, thereby extending the service life of the battery bin. The battery bin body is low in cost and easy to process, thereby enhancing the market competitiveness of the product. By setting the first bin body 1 and the second bin body 2 to cooperate with each other, the two are combined into one in form to form a rectangular battery bin, but the two battery bins are independently powered and do not affect each other. The batteries are easy to disassemble and assemble, and can be used on various three-layer battery bin machines that require battery replacement.
