Specific implementation plan

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this article, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0027] The inventor of this solution found that in the prior art, the battery pack in the power box is installed and disassembled horizontally, which requires additional space for the battery pack to be installed and disassembled, resulting in the power box being too large. Furthermore, the process of horizontal installation and disassembly is also relatively cumbersome, which reduces the user experience. The embodiment of the present invention provides the following solution:

[0028] like Figures 1 to 5 As shown, an embodiment of the present invention provides a backpack power supply box for facilitating battery pack replacement, including a power supply box upper cover 1 and a power supply box base 2, the power supply box upper cover 1 can be rotatably connected to the power supply box base 2, the power supply box base 2 is installed with a circuit board 3 and a plurality of battery packs 4, the power supply box base 2 is installed with a battery board 5, the battery board 5 is provided with a plurality of battery pack installation positions 6, and the battery pack installation positions 6 are provided with a pop-up battery pack installation plate 7. The battery pack installation position 6 is provided with a locker 8, and the battery pack installation plate 7 is provided with a locking head 81 corresponding to the locker 8.

[0029] It should be noted that shoulder straps 9 are connected to both sides of the power box base 2, the battery pack mounting positions 6 are evenly arranged in a matrix, the circuit board 3 is connected to the power cord, and the locker 8 is a push-type locker. When the battery pack 4 needs to be replaced, the power box cover 1 is opened, and the locking head 81 is unlocked and separated from the locker 8 after pressing the battery pack mounting plate 7. The battery pack mounting plate 7 is tilted at a certain angle after popping up, so that the battery pack 4 can be easily removed from the battery pack mounting plate 7. After replacing the new battery pack, the locking head 81 is locked with the locker 8 after pressing the battery pack mounting plate 7, thereby completing the replacement of the new battery pack.

[0030] Power box upper cover 1, power box base 2, first mounting column 21, second mounting column 22, circuit board 3, battery pack 4, battery panel 5, battery pack mounting position 6, rotating seat 61, battery pack mounting plate 7, rotating shaft 71, torsion spring 72, limit plate 73, rounded surface 74, locker 8, locking head 81, shoulder strap 9.

[0031] In some embodiments, a rotating seat 61 is provided on both sides of the battery pack mounting position 6, and a rotating shaft 71 is provided on both sides of the battery pack mounting plate 7. The rotating shaft 71 is sleeved with a torsion spring 72, and the battery pack mounting plate 7 is rotatably connected to the rotating seat 61 through the rotating shaft 71.

[0032] It should be noted that when the battery pack mounting plate 7 is pressed, the locking head 81 is unlocked and separated from the locker 8. Under the action of the torsion spring 72, the battery pack mounting plate 7 is rotated to a certain angle by the rotating shaft 71 and pops open, thereby facilitating the user to disassemble the battery pack.

[0033] In some embodiments, at least one limiting plate 73 is provided at the end of the battery pack mounting plate 7 close to the rotation axis 71. Specifically, the side of the limiting plate 73 facing the battery pack mounting position 6 is an inclined surface, so that the rotation angle of the battery pack mounting plate 7 can be limited, so that the battery pack mounting plate 7 rotates 30 degrees when it pops up, reaching the optimal angle for disassembly and installation.

[0034] In some embodiments, the number of the limiting plates 73 is three, and the limiting plates 73 are arranged linearly and evenly, so as to better limit the rotation angle of the battery pack mounting plate 7 and improve the stability of the battery pack mounting plate 7 during rotation.

[0035] In some embodiments, a rounded surface 74 is provided at the end of the battery pack mounting plate 7 close to the rotating shaft 71, and the limiting plate 73 is connected to the rounded surface 74, so that the battery pack mounting plate 7 can rotate more smoothly when being popped up, thereby improving the stability of the battery pack mounting plate 7 during rotation.

[0036] In some embodiments, the power box base 2 is provided with a plurality of first mounting columns 21, and the circuit board 3 is mounted on the power box base 2 through the first mounting columns 21. The power box base 2 is provided with a plurality of second mounting columns 22, and the height of the second mounting columns 22 is greater than the height of the first mounting columns 21. The battery panel 5 is mounted on the power box base 2 through the second mounting columns 22, and the battery panel 5 is located above the circuit board 3.

[0037] In specific implementation, Figure 6 As shown, when the battery pack 4 needs to be replaced, open the power box cover 1. Figure 7 As shown, after pressing the battery pack mounting plate 7 , the locking head 81 is unlocked and separated from the locker 8 , and the battery pack mounting plate 7 pops up to form a 30-degree oblique angle, thereby facilitating the removal of the battery pack 4 from the battery pack mounting plate 7 .

[0038] To sum up, an embodiment of the present invention provides a backpack power box which is convenient for replacing battery packs. A pop-up battery pack mounting plate and a lock are arranged at the battery pack mounting position, so that the battery pack mounting plate is locked by the lock. When the battery pack mounting seat is unlocked and popped up, the battery pack can be easily installed and removed by the pop-up angle, which also saves unnecessary installation and disassembly space, reduces the overall volume of the battery pack to a great extent, and provides convenience for users when installing and removing the battery pack.
