[0034] Please see Figure 1 and Figure 2 This application provides a detachable battery box, including a housing and a terminal group 30 disposed inside the housing. Specifically, the housing includes a bottom box 10 and a top cover 20. The bottom box 10 has a battery slot 11 for placing batteries. The top cover 20 includes a fixed cover 21 and a movable cover 22. The fixed cover 21 is fixed to the bottom box 10, and the movable cover 22 covers the battery slot 11, with one end rotatably connected to the fixed cover 21 and the other end detachably connected to the bottom box 10. The terminal group 30 includes a positive terminal 31 and a negative terminal 32. One end of the negative terminal 32 is disposed at the bottom of the battery slot 11 and elastically abuts against the battery, while the other end is disposed outside the battery slot 11 and connected to a wire. One end of the positive terminal 31 is disposed at the edge of the battery slot 11 and elastically abuts against the battery, while the other end is disposed outside the battery slot 11 and connected to a wire.

[0035] The removable battery box provided in this embodiment features a movable cover 22 rotatably connected to a fixed cover 21 and detachably connected to a bottom box 10, facilitating battery replacement by opening and closing the movable cover 22. Furthermore, the fixed cover 21 and the movable cover 22 provide partitioned coverage of the bottom box 10, improving safety.

[0036] Please see Figure 2 and Figure 3 Furthermore, in some embodiments, the fixed cover 21 and the bottom box 10 are fixedly connected by a locking member. The fixed cover 21 is provided with a protruding locking post 211, and the bottom box 10 is provided with a through hole 16. The locking member passes through the through hole 16 and locks and is fixedly connected to the locking post 211 to achieve the fixed connection between the fixed cover 21 and the bottom box 10.

[0037] Please see Figure 1-3 Furthermore, in some embodiments, the upper cover 20 is provided with a rotating connection structure to realize the rotating connection between the fixed cover 21 and the movable cover 22. The rotating connection structure can be a hinge structure or a rotating shaft or other structure that can realize the rotating connection between the fixed cover 21 and the movable cover 22.

[0038] In a preferred embodiment, the top cover 20 is provided with a flexible connector 23, which enables the movable cover 22 to rotate and open. One end of the flexible connector 23 is connected to the fixed cover 21, and the other end is connected to the movable cover 22, allowing the movable cover 22 to rotate relative to the fixed cover 21. When it is necessary to open the battery box, only one end of the movable cover 22 needs to be detached from the bottom box 10 and lifted upwards to deflect the movable cover 22. During this process, the flexible connector 23 is deformed under pressure, enabling the movable cover 22 to rotate relative to the fixed cover 21. With this configuration, the top cover 20 can be integrally injection molded, reducing the number of structural parts and simplifying the assembly process. Compared with the traditional rotating connection structure, by providing the flexible connector 23, the top cover 20 has stronger overall integrity and is more conducive to the waterproofing and dustproofing of the battery box.

[0039] Furthermore, in some embodiments, the movable cover 22 and the bottom box 10 are detachably connected by a snap-fit ​​structure; the snap-fit ​​structure includes a hook 221 and a latch 12, one of which is provided on the movable cover 22 and the other on the bottom box 10. When opening the battery box, only an external force needs to be applied to the hook 221 to disengage it from the latch 12; when closing the battery box, only the movable cover 22 needs to be deflected and pressed towards the bottom box 10 to engage the hook 221 with the latch 12, thus realizing the opening and closing of the movable cover 22 relative to the bottom box 10. The overall structure is simple and easy to implement.

[0040] In some other embodiments, the buckle structure can also achieve the engagement and unlocking of the hook 221 and the buckle position 12 by elastically pressing the button, which will not be described in detail here.

[0041] Please see Figure 4-6 Furthermore, in some embodiments, the negative terminal 32 is sequentially provided with an extended first conductive portion 321, a first positioning portion 322, and a first abutting portion 323; a first terminal cutout 111 is opened on the side wall of the battery compartment 11, and the first positioning portion 322 is embedded in the first terminal cutout 111, so that the first abutting portion 323 is placed inside the battery compartment 11 to abut against the battery, and the first conductive portion 321 is placed outside the battery compartment 11 to connect with the wire. In this arrangement, the fixing cover 21 is placed on top of the first conductive portion 321 to avoid touching the first conductive portion 321 when replacing the battery, which can ensure the stability of the connection between the negative terminal 32 and the wire.

[0042] Furthermore, the bottom of the battery compartment 11 is provided with a protruding positioning post 114, and the negative terminal 32 is provided with a positioning hole 3221, in which the positioning post 114 is inserted. Through the synergistic effect of the positioning post 114 and the first terminal cutout 111, the positioning of the negative terminal 32 is achieved, avoiding displacement of the negative terminal 32 in its length and width directions during battery replacement, thereby improving the stability of the electrical connection of the battery box.

[0043] Furthermore, in some embodiments, one end of the positive terminal 31 is provided with a first clamping part 312 clamped between the battery compartment 11 and the inner wall of the bottom box 10. The end of the first clamping part 312 is provided with a second abutting part 314 with a flanged extension. A second terminal cutout 112 is opened on the side wall of the battery compartment 11. The second abutting part 314 is placed at the second terminal cutout 112 and elastically abuts against the battery.

[0044] In a preferred embodiment, the second abutment portion 314 extends and connects to one side of the first clamping portion 312 in the width direction, and bends from one end of the opening of the battery slot 11 towards the bottom of the slot, forming a certain angle with the first clamping portion 312. This arrangement facilitates the pressing and installation of the battery from the opening of the battery slot 11 towards the bottom of the slot.

[0045] Furthermore, in some embodiments, a first clamping groove 13 is provided on the outer wall of the battery compartment 11 near the second terminal cutout 112, and the end of the first clamping part 312 extends and is inserted into the first clamping groove 13 to position the positive terminal 31.

[0046] Furthermore, the positive terminal 31 is also provided with a second clamping part 313 and a second conductive part 311. The second conductive part 311 is connected to the wire, and one end of the second clamping part 313 is connected to the second conductive part 311, while the other end is bent and connected to the first clamping part 312. Similarly, the fixing cover 21 is placed on top of the second conductive part 311 to prevent the second conductive part 311 from being touched when replacing the battery, thus ensuring the stability of the connection between the positive terminal 31 and the wire.

[0047] Furthermore, the bottom box 10 is provided with a second clamping groove 14, which is located outside the battery compartment 11, and the second clamping part 313 is inserted into the second clamping groove 14. With this arrangement, the positive terminal 31 can be further positioned to avoid misalignment of the positive terminal 31, which would affect the connection between the second conductive part 311 and the wire, and thus affect the conductive performance of the positive terminal 31.

[0048] Furthermore, in some embodiments, the bottom box 10 also has a wire outlet hole 15 for wire outlet. It is understood that the wire outlet hole 15 is located on the side wall of the bottom box 10 near the first conductive part 321 and the second conductive part 311, so as to avoid the wires from winding inside the battery box.

[0049] Furthermore, in some embodiments, a finger-position cutout 113 is provided on the side wall of the battery compartment 11 near the deflected end of the movable cover 22 to facilitate battery replacement.

[0050] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0051] (1) By setting the movable cover to be rotatably connected to the fixed cover and detachably connected to the bottom box, it is convenient to open and close the movable cover to replace the battery;

[0052] (2) By setting flexible connectors to connect the fixed cover and the movable cover, the top cover can be integrally formed, which can reduce the number of structural parts and simplify the assembly process;

[0053] (3) The bottom box is partitioned and covered by a fixed cover and a movable cover to improve safety performance;

[0054] (4) By setting the first clamping groove and the second clamping groove to clamp and fix the positive terminal, the conduction stability of the positive terminal can be maintained.

[0055] (5) The negative terminal is fixed by setting the terminal notch and the positioning post working together. The structure is simple, easy to install and easy to implement.

[0056] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
