[0035] See also Figure 1-8 As shown, according to an embodiment of the present invention, a box connection structure is provided, comprising: a main body 1, the main body 1 having a first surface 3 and a second surface 24, the first surface 3 having a plurality of fixing grooves, and the second surface 24 having a plurality of first recesses 5; and a connector 2, wherein between two adjacent main bodies 1, a portion of the connector 2 is engaged in the fixing groove of one main body 1, and the other portion of the connector 2 can be inserted into the first recess 5 of another main body 1 and engaged with the first recess 5. In this technical solution, the connector 2 is detachably engaged in the first recesses 5 and fixing grooves. When multiple main bodies 1 need to be connected, only the two ends of the connector 2 need to be engaged in the first recesses 5 and fixing grooves respectively to complete the connection of two adjacent main bodies 1. The installation structure is convenient for assembly and greatly improves the user experience.

[0036] In some embodiments, the connector 2 includes a first segment 10, a second segment 11, a third segment 12, a fourth segment 13, and a fifth segment 14, which are connected sequentially. The diameters of the second segment 11 and the fourth segment 13 are smaller than the diameter of the first segment 10, the diameter of the second segment 11 and the fourth segment 13 is smaller than the diameter of the third segment 12, and the diameter of the second segment 11 and the fourth segment 13 is smaller than the diameter of the fifth segment 14. In this technical solution, the connector 2 adopts a multi-segment structure, which increases the force-bearing area of ​​the connector 2 and improves the connection strength between two adjacent main bodies 1. The connector 2 can be cylindrical, but other shapes are also acceptable.

[0037] In some embodiments, the fixing groove includes a tenth groove 19 and an eleventh groove 20, which are connected. The width of the eleventh groove 20 is greater than the width of the tenth groove 19. The tenth groove 19 matches the second segment 11. A twelfth groove 23 is provided at the bottom of the tenth groove 19. The width of the twelfth groove 23 is greater than the width of the tenth groove 19 and matches the first segment 10. The width of the eleventh groove 20 is not less than the width of the first segment 10.

In this technical solution, the end faces of the tenth groove 19 and the eleventh groove 20 are connected, and the opening end of the twelfth groove 23 is located at the bottom of the tenth groove 19 and is connected to it. The width of the tenth groove 19 matches the width of the second segment 11, and the width of the twelfth groove 23 matches the width of the first segment 10. During installation, since the width of the eleventh groove 20 is not less than the width of the first segment 10, and the depth of the eleventh groove 20 is equal to the sum of the depths of the tenth groove 19 and the twelfth groove 23, the second segment 11 and the first segment 10 can extend into the eleventh groove 20 and then move towards the tenth groove 19. When they move into the tenth groove 19, the first segment 10 is located in the twelfth groove 23, and the second segment 11 is located in the tenth groove 19. Since the width of the twelfth groove 23 is greater than the width of the tenth groove 19, a snap-fit ​​structure is formed between the first segment 10 and the twelfth groove 23, thereby achieving the purpose of fixing the connector 2.

[0038] In some embodiments, the first groove 5 includes a sliding groove 16 and a second groove 17. The sliding groove 16 has a first end and a second end, and the second groove 17 is located at the first end. The second groove 17 is connected to the sliding groove 16, and the width of the third segment 12, the fourth segment 13, and the fifth segment 14 is not greater than the groove width of the second groove 17. In this technical solution, the sliding groove 16 is arc-shaped, preferably with an arc of 90 degrees. The second groove 17 is connected to the sliding groove 16. Since the width of the third segment 12, the fourth segment 13, and the fifth segment 14 is not greater than the groove width of the second groove 17, during installation, the second segment 11, the third segment 12, the fourth segment 13, and the fifth segment 14 can extend into the second groove 17 and move from the second groove 17 into the sliding groove 16, where they are engaged.

[0039] In some embodiments, the bottom of the sliding groove 16 is provided with a third groove 18, an eighth groove 21 and a ninth groove 22 in sequence. The sliding groove 16, the third groove 18, the eighth groove 21 and the ninth groove 22 are connected in sequence. The sliding groove 16 matches the second segment 11, the third groove 18 matches the third segment 12, the eighth groove 21 matches the fourth segment 13 and the ninth groove 22 matches the fifth segment 14. In this technical solution, the width of the sliding groove 16 matches the width of the second segment 11, the width of the third groove 18 matches the width of the third segment 12, the width of the eighth groove 21 matches the width of the fourth segment 13, and the width of the ninth groove 22 matches the width of the fifth segment 14. The third groove 18, the eighth groove 21, and the ninth groove 22 act as guide rails. During installation, the second segment 11, the third segment 12, the fourth segment 13, and the fifth segment 14 can extend into the second groove 17 and move from the second groove 17 into the sliding groove 16. The second segment 11 is located in the sliding groove 16, the third segment 12 is located in the third groove 18, the fourth segment 13 is located in the eighth groove 21, and the fifth segment 14 is located in the ninth groove 22. The third segment 12 and the third groove 18, and the fifth segment 14 and the ninth groove 22 respectively form limiting structures to limit and fix the connector 2.

[0040] In some embodiments, a fifth groove 9 is sequentially provided at the bottom of the sliding groove 16. The sliding groove 16 and the fifth groove 9 are connected. The fifth groove 9 is located at the bottom of the sliding groove 16 near the second end relative to the second groove 17. A fixing member 4 is movably disposed in the fifth groove 9. A fourth groove 15 is provided on the end face of the fifth segment 14 facing away from the fourth segment 13. When the fifth segment 14 is opposite to the fifth groove 9, the fixing member 4 is at least partially inserted into the fourth groove 15. In this technical solution, when the connecting member 2 moves within the sliding groove 16 to be opposite the fifth groove 9, the fixing member 4 is at least partially inserted into the fourth groove 15. At this time, the fixing member 4 completes the fixation of the connecting member 2, improving the connection strength between the two adjacent housings.

[0041] In some embodiments, a seventh groove 8 is provided at the bottom of the fifth groove 9. The fixing member 4 includes a rod and an end portion, the width of which is greater than the width of the rod. The seventh groove 8 matches the end portion, and the fifth groove 9 matches the rod portion. The sum of the groove depths of the seventh groove 8 and the fifth groove 9 is not less than the length of the fixing member 4. In this technical solution, the groove width of the fifth groove 9 is less than the groove width of the seventh groove 8. The fifth groove 9 and the seventh groove 8 are connected. The fixing member 4 can be a pin, connected to the fifth groove 9 via the seventh groove 8, with the end portion located within the seventh groove 8. The seventh groove 8 limits the fixing member 4, ensuring both normal movement and preventing it from falling off.

[0042] In some embodiments, a sixth groove 7 is provided at the bottom of the fifth groove 9, and a driving member 6 is provided in the sixth groove 7. The driving member 6 is used to drive the fixing member 4 to move along the depth direction of the fifth groove 9. In this technical solution, the sixth groove 7 is provided at the bottom of the seventh groove 8, and the sixth groove 7 and the seventh groove 8 are connected. The driving member 6 is an electromagnet. A first sensing unit can be provided in the second groove 17. When the connecting member 2 extends into the second groove 17, the sensing unit senses the connecting member 2, thereby controlling the electromagnet to be energized. Under the action of magnetic force, the fixing member 4 moves towards the bottom of the groove until it is attracted to the electromagnet. A second sensing unit is provided at the fifth groove 9. When the connecting member 2 moves to be opposite to the fifth groove 9, the electromagnet is de-energized, and the fixing member 4 moves downward under the action of gravity until it is partially inserted into the fourth groove 15, thus completing the installation of the two adjacent main bodies 1. Of course, the driving member 6 can also be other types, as long as it can drive the fixing member 4.

[0043] When disassembling two adjacent main bodies 1, first control the electromagnet to be energized. Under the action of magnetic force, the fixing part 4 moves towards the bottom of the groove until it is attracted to the electromagnet. At this time, the fixing part 4 is pulled out from the fourth groove 15. Then the connecting part 2 moves towards the second groove 17 in the sliding groove until it moves into the second groove 17 and is taken out. The disassembly method of the fixing groove is the opposite of the installation method, thus completing the disassembly of two adjacent main bodies 1.

[0044] Furthermore, an electromagnet energizing switch can be installed on the main body 1. When the main body is not assembled, the electromagnet can be de-energized by the energizing switch, saving energy and avoiding resource waste.

[0045] In some embodiments, a thirteenth groove 25 is provided on the outer peripheral wall of the third segment 13 along its circumference, and a plurality of balls are disposed within the thirteenth groove 25. In this technical solution, the thirteenth groove 25 is annular, and the thirteenth groove 25 and the balls make the movement of the connector 2 in the sliding groove smoother. Of course, the third segment 13 can also adopt a bearing structure, which includes an outer ring fitted around the center portion, and a plurality of balls are disposed between the outer ring and the center portion. The outer ring can rotate relative to the center portion, thereby ensuring that the movement of the connector 2 in the sliding groove is smoother.

[0046] Furthermore, multiple casters can be provided on the first surface 3 or the second surface 24 of the main body 1 to facilitate the movement of the main body 1. When the main body is used as a mobile power source, it can serve as a power supply box, solar panel box, etc.

[0047] The modular design of the enclosure connection structure of this invention allows users to select various functional modular enclosures, such as power supply enclosures, solar panel enclosures, and cooking enclosures, before heading out for outdoor activities. During assembly, each module is installed using rotating locking mechanisms on the modules and positioning pins controlled by electromagnets, making installation convenient for users.

[0048] This invention's enclosure connection structure is not limited to a power supply box; it can also be designed as a variety of multifunctional modular boxes. These can be used to store outdoor first-aid tools, kitchen tools, etc. For example, for easy movement, a base modular box with casters can be assembled. When power is insufficient, a modular box with a solar panel can be assembled. From top to bottom, the modules are: a solar panel modular box, a power supply modular box, and a base modular box. Each modular box contains an independent battery. When multiple modular boxes are stacked and connected in parallel, the power output increases.

[0049] The present invention also provides a portable power supply, including the aforementioned housing connection structure.

[0050] The power bank body is the aforementioned main body 1. The power bank of this invention features a modular design, allowing users to customize the assembly of the mobile module boxes according to their specific usage scenarios. Furthermore, each module assembly utilizes a simple and ingenious installation structure, facilitating assembly and significantly improving the user experience.
