[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The technical solution of a battery box provided by various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Reference Figures 1 to 9 As shown, this utility model embodiment provides a battery box, including an upper cover 1 and a bottom box 2. The upper cover 1 is hinged and rotatably connected to the bottom box 2. The upper cover 1 is provided with a sealing ring 11 that seals with the bottom box 2. The sealing ring between the upper cover 1 and the bottom box 2 ensures that moisture will not enter the battery box during outdoor use. A latching switch structure 3 for closing and fixing is provided between the upper cover 1 and the bottom box 2. There are two latching switch structures 3, which are symmetrically arranged. A fixing structure 4 is provided on the upper cover 1 and the bottom box 2 and located between the two latching switch structures 3. A partition 20 is provided inside the bottom box 2, which divides the inside of the bottom box 2 into a battery compartment 21 and a storage compartment 22. A switch button structure for powering on the battery box is provided on the upper cover 1.

[0036] In this embodiment, each of the latching switch structures 3 includes a rotating shaft 31, a toggle block 32, a latching block 33, and a latching seat 34. The rotating shaft 31 is horizontally positioned at the top of the toggle block 32. The upper cover 1 is provided with two semi-circular latching seats 13 for rotating and supporting the rotating shaft 31. The two ends of the rotating shaft 31 rotate on the two semi-circular latching seats 13. The latching block 33 is located on the toggle block 32. The bottom of the toggle block 32 has an outward-curved structure. The latching seat 34 is located on the bottom box 2. The latching seat 34 and the latching block 33 are interlocked.

[0037] When in use, the two latching switch structures 3 can be operated simultaneously with both hands or in stages.

[0038] After closing the top cover 1 on the bottom box 2, press down on the outward-curved structure of the lever 32, causing the lever 32 to rotate on the two semi-circular brackets 13 via the pivot 31. This causes the latching block 33 on the lever 32 to engage with the latching bracket 34, thus achieving a fixed connection between the top cover 1 and the bottom box 2. This structure, through the rotation and latching principle of the lever 32, forms a stable fastening effect, which can effectively improve the tightness and reliability of the top cover 1 and the bottom box 2 after assembly.

[0039] In this embodiment, the fixing structure 4 includes an upper fixing block 41 located in the middle of the upper cover 1 and a lower fixing block 42 located in the middle of the bottom box 2. The upper fixing block 41 and the lower fixing block 42 are respectively provided with an upper threaded hole 43 and a lower threaded hole 44, and a fixing screw is provided between the upper threaded hole 43 and the lower threaded hole 44. The fixing screw is a PB2.0*8MM anti-loosening half-thread screw.

[0040] After the upper cover 1 and the bottom box 2 are closed by the two snap-on switch structures 3, the fixing screws are tightened into the upper threaded holes 43 and the lower threaded holes 44 inside the upper fixing block 41 and the lower fixing block 42, respectively, thereby achieving secondary fixation of the upper cover 1 and the bottom box 2. This design makes it impossible to separate the upper cover 1 and the bottom box 2 without the assistance of professional tools, which significantly enhances the structural safety and anti-accidental opening performance of the battery box.

[0041] In this embodiment, the battery compartment 21 is provided with three sets of battery placement cavities 23; the three sets of battery placement cavities 23 can hold three sets of batteries.

[0042] In this embodiment, the placement compartment 22 is equipped with a horizontally arranged PCBA circuit board 5. The PCBA circuit board 5 uses a 6*6*4.3MM surface mount switch, which saves both material and labor costs, greatly reduces packaging space for the finished circuit board, and also reduces damage to the PCBA circuit board 5 during transportation.

[0043] The PCBA circuit board 5 is provided with a switch 51, and the placement compartment 22 is provided with a horizontally arranged pressure plate 6. The pressure plate 6 is provided with a notch 61, and a horizontally arranged elastic sheet 62 is provided at the notch 61. The elastic sheet 62 is provided with a cylinder 63 located above the switch 51. The switch button structure includes a button cap 7. The upper cover 1 is provided with a circular hole 12 for installing the button cap 7. The bottom of the button cap 7 is provided with a pressing post 71. The pressing post 71 corresponds to the position of the cylinder 63, achieving seamless contact between the pressing post 71 and the cylinder 63, enhancing the feel of pressing the switch, saving the cost of the switch, reducing the packaging cost of the circuit board, and significantly reducing the product defect rate.

[0044] When operating the battery box power switch, pressing down on the button cap 7 causes its bottom pressing post 71 to align with the cylinder 63. This causes the cylinder 63 to deform and move downwards via the elastic sheet 62, bringing the bottom of the cylinder 63 into contact with the switch 51 on the PCBA circuit board, thus turning on the switch and providing power. After pressing, the elastic sheet 62 resets, causing the cylinder 63 to move upwards, disengaging the bottom of the cylinder 63 from the switch 51, completing the power-off reset. This structure, through its elastic linkage design, achieves stable triggering and reset of the switch, ensuring the reliability of power supply control.

[0045] Example 1 of bottom box 2: Refer to Figure 8 As shown,

[0046] In this embodiment, the bottom box 2 is provided with an arc-shaped outlet hole 8 on the side of the placement compartment 22.

[0047] Example 2 of bottom box 2: Refer to Figure 9 As shown,

[0048] In this embodiment, the bottom box 2 is provided with a cable outlet arc-shaped hole 8 on the side of the placement compartment 22, and a TRY-ME hole 9 is provided on the side of the cable outlet arc-shaped hole 8. The TRY-ME hole 9 is provided with a TRY-ME female connector interface 91 that is electrically connected to the PCBA circuit board 5, and a detachable silicone part 92 is provided at the TRY-ME hole 9.

[0049] When using the TRY-ME female connector 91, simply remove the silicone part 92. When not in use, the TRY-ME hole 9 can be covered by the silicone part 92.

[0050] The arc-shaped outlet hole 8 allows external wires on the PCBA circuit board 5 to extend outward from the battery box.

[0051] In this embodiment, the bottom box 2 has a hanging ring 10 on the side wall opposite to the arc-shaped outlet hole 8. The hanging ring 10 can hang the battery box in the desired position during use. Since the hanging ring 10 is set opposite to the arc-shaped outlet hole, rainwater will not seep into the battery box along the wires during use.

[0052] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
