[0087] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0088] With the increasing popularity of smart devices, more and more smart door locks are coming into view and attracting widespread attention from consumers. Currently, there are many types of door locks on the market, each with its own features. However, in terms of power supply installation, they all adopt a structure where the panel and power supply 30 are separately installed. When users need to charge, they need to first remove the panel and then pull the power supply 30 out of the power supply compartment of the door lock. This is inconvenient and time-consuming when there are many power supplies 30 in the compartment, requiring the removal of each one sequentially. Furthermore, when multiple power supplies 30 are located far from the panel in the power supply compartment, it is difficult for a person to reach inside the compartment and quickly retrieve the power supplies 30, further causing inconvenience for users.

[0089] To address the technical problem in the prior art that the power supply 30 inside the door lock cannot be quickly retrieved for charging, according to one aspect of this application, a power supply device for a door lock is provided, comprising:

[0090] A housing 10, for detachable connection with a door lock, wherein the housing 10 is the panel of the door lock, and,

[0091] The housing 20 includes a receiving compartment 21 for accommodating a power supply 30 that supplies power to the door lock. The housing 20 is fixed to the side of the housing 10 facing the door lock.

[0092] refer to Figure 1 and Figure 2As shown, the power supply 30 is fixed by the receiving compartment 21 inside the box 20, so that the box 20 is fixed to the side of the housing 10 facing the door lock. Since the housing 10 is the panel of the door lock, the housing 10 is detachably assembled to the door lock. Therefore, when the user needs to charge the power supply 30, he only needs to remove the housing 10 from the door lock, and the box 20 can be directly taken out by the housing 10 to charge the power supply 30 inside the box 20. In this way, removing the housing 10 and taking out the power supply 30 can be completed in one step, simplifying the disassembly steps, making the operation simple, saving time, and improving the convenience for users during use.

[0093] refer to Figures 1-3 As shown, according to one embodiment of this application, wherein

[0094] The shell 10 and the box body 20 are integrally formed, or,

[0095] The shell 10 and the box 20 are separate molded parts, and the shell 10 and the box 20 are assembled and fixed.

[0096] In one embodiment, the housing 10 and the box 20 are integrally formed structures. The housing 10 and the box 20 can be injection molded from the same material. After the housing 10 is removed from the door lock position, the power supply 30 in the receiving compartment 21 is naturally removed along with the box 20 and the housing 10, thereby realizing the quick removal of the power supply 30.

[0097] In another embodiment, the housing 10 and the box 20 are separate molded parts, and the box 20 is detachably assembled to the housing 10. This allows the structure and materials of the housing 10 and the box 20 to be processed separately according to different usage requirements, so as to meet the requirements of the structure and materials of the housing 10 and the box 20 under different usage conditions.

[0098] According to one embodiment of this application, the housing 20 includes:

[0099] Control compartment 22, for accommodating the door lock control component 40;

[0100] An electrical connection compartment 23 is disposed between the control compartment 22 and the receiving compartment 21, and the control component 40 and the power supply 30 are electrically connected through the electrical connection compartment 23.

[0101] The control compartment 22 is connected to the receiving compartment 21 through the electrical connection compartment 23, so that the power supply 30 can be easily electrically connected to the control component 40 through the electrical connection compartment 23. The connection can be made by passing an electrical connection wire through the electrical connection compartment 23. The control component 40 can be set as a circuit board, which is used to electrically connect to the door lock. The power supply 30 supplies power to the door lock through the control component 40.

[0102] The control unit 40 may include a power level indicator that reminds the user to charge the power supply 30 when the power level of the power supply 30 is insufficient to power the door lock. As an example, the power level indicator may be an indicator light.

[0103] The control unit 40 is provided with an external port 41. After the power supply 30 is electrically connected to the control unit 40, it supplies power to the door lock through the external port 41, or the control unit 40 charges the power supply 30 through the external port 41.

[0104] refer to Figure 3 As shown, the housing 21 and control compartment 22 within the box 20 allow the user to directly remove the power supply 30 assembly, consisting of the power supply 30 and control component 40, when disassembling the housing 10. This improves the integration of the device and enhances the stability of the electrical connection between the control component 40 and the power supply 30. Compared to existing technologies, it eliminates the need to align each power supply 30 with the electrical connection point inside the door lock after charging, which is time-consuming and could lead to misalignment of the power supply 30 with the electrical connection point inside the door lock, causing inconvenience.

[0105] By setting a control compartment 22 inside the housing 20, assembling a control component 40 in the control compartment 22, and achieving a stable electrical connection between the power supply 30 in the housing 21 and the control component 40 through the electrical connection compartment 23, the stability of the electrical connection is improved. Furthermore, the control component 40 enables rapid charging of the power supply 30. At the same time, when multiple power supplies 30 are provided, it is convenient to quickly connect the control component 40 to the door lock, further simplifying the user's operation steps.

[0106] According to one embodiment of this application, the housing 20 includes a stop 24 disposed within the electrical connection compartment 23 to limit the relative displacement of the control unit 40 or the power supply 30 relative to the electrical connection compartment 23. (Reference) Figure 2 , Figure 3 and Figure 4As shown, the receiving chamber 21 can communicate with the control chamber 22. By setting a stop 24, the assembly position of the power supply 30 relative to the receiving chamber 21 is restricted, and the relative displacement of the control component 40 relative to the control chamber 22 is restricted by the stop 24.

[0107] In one embodiment, a stop 24 disposed within the electrical connection compartment 23 restricts the distance the power supply 30 can move from the receiving compartment 21 to the electrical connection compartment 23, and the stop 24 also restricts the distance the control component 40 can move to the electrical connection compartment 23. This provides sufficient space for the electrical connectors used for electrical connection between the power supply 30 and the control component 40, and effectively prevents the power supply 30 from bumping into the control component 40 as it passes through the electrical connection compartment 23, thereby improving the fixing effect between the power supply 30 and the control component 40 and enhancing the overall mechanical stability of the power supply device.

[0108] According to one embodiment of this application, a limiting groove 221 is provided in the control compartment 22, and the control component 40 is assembled in the limiting groove 221 to limit and fix the control component 40 within the control compartment 22. (Reference) Figure 2 and Figure 3 As shown, the limiting grooves 221 can be symmetrically arranged on both sides of the control chamber 22. One side of the control component 40 is fixed by one limiting groove 221, and the other side of the control component 40 is fixed by the other limiting groove 221, so that the electrical connection surface of the control component 40 faces the electrical connection chamber 23. The limiting grooves 221 limit the relative displacement of the control component 40 in the control chamber 22, thereby improving the limitation of the assembly position of the control component 40.

[0109] In one embodiment, the control component 40 can be configured as a circuit board, and the limiting groove 221 can be configured as a sliding groove. The control component 40 can be slidably assembled in the limiting groove 221. In addition to improving the limiting effect on the control component 40, the assembly effect is further improved. When it is necessary to disassemble or replace the circuit board, it can be quickly disassembled or installed and aligned, thereby improving the stability of the electrical connection between the power supply 30 and the control component 40.

[0110] According to one embodiment of this application, it includes:

[0111] A first cover 50 is disposed at the first opening end 222 of the control compartment 22. The first cover 50 is detachably connected to the box body 20 so that the control component 40 is located in the sealed cavity formed by the first cover 50 and the control compartment 22.

[0112] The second cover 60 is disposed at the second opening end 211 of the receiving chamber 21. The second cover 60 is detachably connected to the box body 20 so that the power supply 30 is located in the sealed cavity formed by the second cover 60 and the receiving chamber 21.

[0113] In one embodiment, the control component 40 is assembled into the control compartment 22 through the first opening end 222, and the power supply 30 is assembled into the receiving compartment 21 through the second opening end 211. (Refer to...) Figure 5 As shown, the first cover 50 faces the first opening end 222 and is detachably connected to the box body 20, so that the control component 40 is located in the sealed cavity formed by the first cover 50 and the control compartment 22. The first cover 50 improves the protection of the control component 40, prevents the control component 40 from falling out of the first opening end 222, avoids accidental contact, and avoids damage to the control component 40.

[0114] In addition, refer to Figure 6 As shown, the second cover 60 faces the second opening end 211 and is detachably connected to the box body 20, so that the power supply 30 is located in the sealed cavity formed by the second cover 60 and the receiving compartment 21. The second cover 60 improves the protection effect of the power supply 30 and prevents the power supply 30 from coming out of the second opening end 211.

[0115] refer to Figure 5 and Figure 6 As shown, according to one embodiment of this application, a first sliding mechanism 51 is provided between the first cover 50 and the box body 20, and the first cover 50 is slidably assembled with the box body 20 through the first sliding mechanism 51.

[0116] The second cover 60 and the box body 20 are provided with a second sliding mechanism 61, and the second cover 60 is slidably assembled with the box body 20 through the second sliding mechanism 61.

[0117] In one embodiment, the first sliding mechanism 51 can be configured as a structure in which a sliding groove and a sliding rail cooperate with each other, with the sliding groove disposed on the first cover 50 and the sliding rail disposed on the box body 20 at the first opening end 222, or the sliding groove disposed on the box body 20 at the first opening end 222 and the sliding rail disposed on the box body 20 at the first opening end 222, so that the first cover 50 and the box body 20 are slidably connected through the first sliding mechanism 51.

[0118] The second sliding mechanism 61 can be configured as a structure in which a sliding groove and a sliding rail cooperate with each other, with the sliding groove set on the second cover 60 and the sliding rail set on the box body 20 at the second opening end 211, or the sliding groove set on the box body 20 at the second opening end 211 and the sliding rail set on the box body 20 at the second opening end 211, so that the second cover 60 and the box body 20 are slidably connected through the second sliding mechanism 61.

[0119] According to one embodiment of this application, a second limiting member 54 is provided between the first cover 50 and the box body 20 to limit the relative displacement between the first cover 50 and the box body 20 by the second limiting member 54.

[0120] The second cover 60 and the box body 20 have a third limiting member 62 to limit the relative displacement between the second cover 60 and the box body 20.

[0121] In one embodiment, see Figures 6-8 As shown, after the first cover 50 is slid to the position where the box body 20 is assembled via the first sliding mechanism 51, the relative displacement of the first cover 50 and the box body 20 in the sliding direction can be limited by the second limiting member 54, so that the first cover 50 can be fixed in the relative position with the box body 20, and the first cover 50 will be prevented from sliding out in the sliding direction.

[0122] Similarly, after the second cover 60 is slid to the position where the box body 20 is assembled via the second sliding mechanism 61, the relative displacement of the second cover 60 and the box body 20 in the sliding direction can be limited by the third limiting member 62, so that the second cover 60 can be fixed in the relative position with the box body 20, and the second cover 60 will be prevented from sliding out in the sliding direction.

[0123] See Figure 9As shown, in one embodiment, the control compartment 22 can be disposed at the top of the box body 20, and the receiving compartment 21 can extend from the top of the box body 20 to the bottom of the box body 20. The electrical connection compartment 23 is disposed between the control compartment 22 and the receiving compartment 21. The first opening end 222 faces the door lock, and the second opening end 211 faces the bottom of the box body 20. When assembling the control component 40, the control component 40 is slidably fixed by the first opening end 222 in the limiting groove 221 extending along the second direction 100. Then, the first cover 50 is detachably assembled with the box body 20 facing the first opening end 222 via the first sliding mechanism 51. In this way, a sealed cavity is formed between the first cover 50 and the control compartment 22. On the one hand, the assembly position of the control component 40 is further limited, and on the other hand, the stability of the overall mechanical structure is improved, avoiding damage to the control component 40.

[0124] The power supply 30 is fixed in the receiving compartment 21 by the second opening end 211 along the first direction 90. The second cover 60 facing the second opening end 211 is detachably assembled with the box body 20 through the second sliding mechanism 61. In this way, a sealed cavity is formed between the second cover 60 and the receiving compartment 21, which further limits the assembly position of the power supply 30, preventing the power supply 30 from coming out of the second opening end 211. At the same time, it is convenient to replace the power supply 30 through the second cover 60, improving the convenience of use.

[0125] In one embodiment, the first direction 90 and the second direction 100 are angled to further facilitate disassembly by the user through the first cover 50 or the second cover 60 when maintenance or replacement of the control component 40 or the power supply 30 is required, providing a larger disassembly space. As an example, the first direction 90 can be a vertical direction, and the second direction 100 can be a horizontal direction.

[0126] According to one embodiment of this application, the first cover 50 includes a first limiting member 52 and an external interface 53, the control member 40 includes an external port 41, the power supply 30 is charged or discharged through the external port 41, the external port 41 is electrically connected to an external power supply 30 or a door lock through the external interface 53, and the first limiting member 52 is disposed on the periphery of the external interface 53 to limit the relative displacement between the external port 41 and the external interface 53.

[0127] refer to Figure 6 , Figure 7 and Figure 9As shown, the control component 40 includes an external port 41. The first cover 50 has an external interface 53 facing the external port 41. The external port 41 is electrically connected to the internal electrical connection of the door lock through the external interface 53 to supply power to the door lock. Alternatively, the external port 41 is electrically connected to an external power supply 30 through the external interface 53 to charge the power supply 30 in the receiving compartment 21 through the control component 40. This facilitates charging the power supply 30 in the receiving compartment 21. Furthermore, to prevent displacement between the external port 41 and the external interface 53, a first limiting member 52 is provided on the periphery of the external interface 53 to increase the displacement of the external port 41 relative to the external port 41 of the first cover 50, thereby improving the stability of the connection between the external port 41 and the door lock or the external power supply 30 and preventing relative displacement.

[0128] According to one embodiment of this application, a limiting mechanism 70 is included, which is disposed between the housing 20 and the door lock, and the housing 20 is detachably assembled to the door lock 110 through the limiting mechanism 70.

[0129] In one embodiment, reference Figure 10 As shown, the housing 10 drives the box 20 to be detachably connected to the door lock along the second direction 100. The limiting mechanism 70 is disposed on the housing 10 or the box 20. The limiting mechanism 70 limits the relative displacement of the box 20 and the door lock in the second direction 100. Thus, when the box 20 reaches the preset fixed position, the limiting mechanism 70 can fix it to the door lock, thereby limiting the relative displacement between the box 20 or the housing 10 and the door lock in the second direction 100.

[0130] In one embodiment, the limiting mechanism 70 may be configured as a structure that engages with a buckle and a slot, so that the housing 10 and the box 20 can be assembled in a preset fixed position, thereby improving the convenience of use.

[0131] refer to Figure 11 , Figure 12 and Figure 13 As shown, according to one embodiment of this application, the limiting mechanism 70 includes a first snap-fit ​​member 71 and an elastic member 72. A second snap-fit ​​member 80 adapted to the first snap-fit ​​member 71 is provided between the box body 20 and the door lock so that the box body 20 and the door body snap-fit ​​each other, fixing the assembly position between the box body 20 and the door body, and improving the convenience of disassembly.

[0132] The elastic member 72 pushes against the first latching member 71 to engage with the second latching member 80, thereby limiting the relative displacement between the box body 20 and the door lock. The elastic force of the elastic member 72 pushes against the first latching member 71 to engage with the second latching member 80, thereby fixing the box body 20 and the door lock.

[0133] The elastic element 72 contracts, causing the first latching member 71 to release the second latching member 80, so that the housing 20 can be displaced relative to the door lock. In another embodiment, after the elastic element 72 is compressed, it contracts, causing the first latching member 71 to move away from the second latching member 80, so that the first latching member 71 releases the second latching member 80, thereby separating the housing 10 and the housing 20 from the door lock, making it convenient for the user to disassemble and install the power supply 30.

[0134] In one embodiment, the housing 20 is assembled within the power supply compartment of the door lock along the second direction 100. The control component 40 is electrically connected to the power supply compartment's electrical connection point to supply power to the door lock. One end of the elastic member 72 along the first direction 90 abuts against the housing 20, and the other end abuts against the first latching member 71. The housing 20 is provided with an assembly platform 25, and one end of the elastic member 72 abuts against the assembly platform 25. The assembly platform 25 provides a force-bearing support point for the elastic member 72. The elastic member 72 drives the first latching member 71 to engage with the second latching member 80 along the first direction 90, thereby preventing relative displacement between the housing 20 and the shell 10 and the door body in the second direction 100.

[0135] In the example, reference is made to Figures 10-13 As shown, according to one embodiment of this application, the first snap-fit ​​member 71 includes:

[0136] A crimping portion 712 protrudes from the housing 10 to serve as a point of force for the user to compress or release the elastic element 72.

[0137] The latching part 713 is used to limit and latch with the second latching member 80. The elastic member 72 abuts against the latching part 713. The elastic member 72 drives the latching part 713 to move along the first direction 90 so that the latching part 713 can latch or release the second latching member 80. From the second direction 100, the relative displacement between the housing 20 and the door lock in the installation direction is limited.

[0138] Furthermore, when it is necessary to charge the power supply 30, an external force is applied to the crimping part 712 to control the elastic member 72 to contract so that the latching part 713 releases the second latching member 80; in this way, the box body 20 and the housing 10 can be separated from the door lock, which facilitates charging the power supply 30 and saves time.

[0139] However, when the power supply 30 needs to be installed, the box 20 is first assembled into the power supply compartment of the door lock. As an example, the assembly direction is along the second direction 100. The external force of the crimping part 712 is removed, thereby causing the crimping part 712 to control the release of the elastic member 72, so that the snap-fit ​​part 713 snaps into the second snap-fit ​​member 80. Then, the snap-fit ​​part 713 and the second snap-fit ​​member 80 limit the relative displacement of the box 20 and the housing 10 between the door lock and the second direction 100.

[0140] refer to Figures 1-4 As shown, according to one embodiment of this application, a pull-out member 12 is included. The pull-out member 12 is disposed on the side of the housing 10 facing the outside, so that the box body 20 can be detachably connected to the door lock along the second direction 100 by the pull-out member 12. The pull-out member 12 can serve as a force point for the user to pull the box body 20 and the housing 10 in the second direction 100, further improving the convenience for the user when disassembling or installing the box body 20.

[0141] In one embodiment, the pull-out member 12 may be configured as a handle that protrudes outward from the housing 10.

[0142] In another embodiment, according to one implementation of this application, the pull-out member 12 is a recessed groove structure that is recessed towards the door lock side, which can reduce the space occupied by the housing 10. At the same time, the pull-out member 12 with the groove structure can also serve as a force point for pulling the housing 10 to move along the second direction 100, thereby improving the convenience of use.

[0143] According to one embodiment of this application, the limiting mechanism 70 includes a fixing member 73, the fixing member 73 including a first limiting cavity 731 and a second limiting cavity 732, the first locking member 71 is assembled in the first limiting cavity 731, and the elastic member 72 is assembled in the second limiting cavity 732. The elastic member 72 pushes the first locking member 71 to reciprocate relative to the first limiting cavity 731 along a first direction 90, so that the first locking member 71 engages or releases the second locking member 80, and the second limiting cavity 732 controls the movement of the first locking member 71. The elastic contraction and release direction of the elastic element 72 is defined. The first limiting cavity 731 defines the snap-fit ​​direction between the first snap-fit ​​element 71 and the second snap-fit ​​element 80, so that the first snap-fit ​​element 71 and the second snap-fit ​​element 80 can be stably snapped together. The elastic contraction and release direction of the elastic element 72 is the same as the snap-fit ​​direction between the first snap-fit ​​element 71 and the second snap-fit ​​element 80, which improves the conversion efficiency of the elastic force of the elastic element 72. When the user needs to disassemble or install the box 20, the operation is not only simple but also saves effort.

[0144] refer to Figure 13 and Figure 14 As shown, according to one embodiment of this application, the fixing member 73 includes an assembly part 74. The fixing member 73 is fixed to the housing 20 or the door lock through the assembly part 74. The fixing member 73 is fixed to the housing 10 and the housing 20 through the assembly part 74 and the fixing member 73, which improves the stability of the first snap-fit ​​member 71 in the process of snapping the second snap-fit ​​member 80, and the stability of the elastic member 72 in the process of elastic contraction and release, avoids the first snap-fit ​​member 71 and the elastic member 72 from tilting, and improves the stability of the housing 20 in the process of disassembly or installation.

[0145] As an example, in actual use, refer to Figure 16 As shown, the assembly part 74 can be provided with a screw hole, and the fastener 73 can be fixed to the housing 10 by screw thread connection with the screw hole at the corresponding position of the housing 10 through screw.

[0146] Preferred options are available for reference. Figure 17 and Figure 18 As shown, the bottom of the fixing member 73 is provided with an abutment platform 735, which can be abutted against the assembly platform 25. The top of the fixing member 73 is provided with an assembly part 74, which is detachably connected to the housing 10 or the box body 20, thereby improving the assembly efficiency through the abutment platform 735.

[0147] In one embodiment, reference Figures 10-15As shown, sliders 714 are provided on both sides of the first snap-fit ​​member 71, and the fixing member 73 is provided with a movable cavity 734, so that the end of the slider 714 is close to the inner wall of the movable cavity 734. The movable cavity 734 extends along the first direction 90, and the slider 714 slides in the movable cavity 734 along the first direction 90. The slider 714 and the movable cavity 734 prevent the first snap-fit ​​member 71 from shifting to both sides during the sliding along the first direction 90, thereby further improving the stability of the first snap-fit ​​member 71 and the second snap-fit ​​member 80 during the assembly process.

[0148] Preferably, the movable cavity 734 can be disposed between the first limiting cavity 731 and the second limiting cavity 732, reducing the tilt of the end of the first locking member 71 from the middle, thereby further improving the stability of the first locking member 71 and the second locking member 80 during the assembly process.

[0149] Preferred, Reference Figure 15 As shown, protrusions 736 are provided at both ends of the movable cavity 734. The protrusions 736 limit the maximum movement range of the slider 714 within the movable cavity 734. On the one hand, this protects the elastic member 72 from excessive external force, preventing it from exceeding its maximum engagement range and improving its service life. On the other hand, it limits the maximum movement range of the first locking member 71, so that the first locking member 71 and the second locking member 80 can be stably engaged.

[0150] According to one embodiment of this application, the first snap-fit ​​member 71 includes a guide post 711 extending along a first direction 90, and the elastic member 72 is slidably fitted to the guide post 711 to limit the contraction or release of the elastic member 72 along the first direction 90 by the guide post 711. (Reference) Figures 10-19 As shown, the elastic element 72 can be configured as a spring or a sheet, so that the elastic element 72 is sleeved on the guide post 711, further defining the snapping direction between the snapping part 713 and the second snapping member 80, and improving the stability during the snapping process.

[0151] According to one embodiment of this application, the fixing member 73 includes a third limiting cavity 733, and the free end of the guide post 711 extends into the third limiting cavity 733 to limit the reciprocating movement of the guide post 711 in the first direction 90 by means of the third limiting cavity 733. The guide post 711 can slide in the extending direction of the third limiting cavity 733, and the free end of the guide post 711 always slides within the third limiting cavity 733. Furthermore, the first snap-fit ​​member 71 is limited to snap-fitting with the second snap-fit ​​member 80 in the first direction 90.

[0152] According to one embodiment of this application, the housing 10 includes a press-fit interface 11, and the press-fit portion 712 protrudes from the housing 10 through the press-fit interface 11. The press-fit portion 712 slides within the press-fit interface 11 along a first direction 90 to drive the elastic member 72 to contract or release.

[0153] refer to Figures 2-4 and Figure 19 As shown, the crimping interface 11 restricts the sliding direction of the crimping part 712. The crimping interface 11 has a groove 111 on the side facing the first snap-fit ​​member 71. The crimping part 712 protrudes from the crimping interface 11 through the groove 111. The groove 111 further improves the stability of the crimping part 712 during the sliding process.

[0154] In one embodiment, reference Figures 1-19 As shown, the entire power supply assembly includes the main shell of the battery box (equivalent to the housing 10), the pressing block (equivalent to the first snap-fit ​​component 71), the spring (equivalent to the elastic component 72), the fixing block (equivalent to the fixing component 73), screws, the circuit board (equivalent to the control component 40), the upper cover of the battery box (equivalent to the first cover 50), the lower cover of the battery box (equivalent to the second cover 60), and the lithium-ion battery (equivalent to the power supply 30).

[0155] The entire assembly sequence is as follows: First, the spring is mounted on the fixing post (equivalent to guide post 711) of the lower pressure block. Then, the lower pressure block is placed in the fixing block. Finally, the fixing block can be connected to the top of the battery box main shell by screws.

[0156] Next, the circuit board is fixed in the guide groove (equivalent to the limiting groove 221) of the main shell of the battery box, and the battery is placed in the battery slot (equivalent to the receiving compartment 21) of the main shell of the battery box from below.

[0157] Finally, assemble the top and bottom covers of the battery box with the main shell of the battery box.

[0158] The upper part has a limiting structure 1, which is used to position the fixed block.

[0159] The guide groove provides guidance and fixation for the installation of the circuit board.

[0160] Limiting structure 2 restricts the battery's position, ensuring sufficient space between the battery and the circuit board. Once the battery reaches the limiting structure 2, it cannot move forward, thus controlling its position. A gap exists between the circuit board and the battery for subsequent wiring. The circuit board's position depends on the location of its discharge plug; placing it near the top reduces overall space requirements.

[0161] The latch slot engages with the latches on the top and bottom covers of the battery compartment to secure the covers in place.

[0162] The battery compartment can hold four batteries, and the internal space is designed to accommodate the batteries.

[0163] The handle structure (equivalent to pull-out part 12) is located on the surface of the battery compartment, providing a point of leverage for pulling out the battery.

[0164] The fixing structure of the battery box cover (equivalent to the external interface 53 and the second limiting member 54) is used to fix the output port on the circuit board. The buckle at the position of the first cover 50 (equivalent to the first limiting member 52) cooperates with the buckle groove of the main shell of the battery box and is fixed.

[0165] The buckle on the bottom cover of the battery box (equivalent to the second limiting component 54) also engages with and is fixed to the buckle slot of the main shell of the battery box.

[0166] The cylinder below the pressure block (equivalent to guide post 711) is used to fix the spring, and the first snap-fit ​​member 71 includes a lateral protruding structure (equivalent to crimping part 712) which provides the force point for pressing the spring.
