Description

Technical Field

[0001] This utility model belongs to the field of portable power supply products, and specifically relates to a stackable charging box. Background Technology

[0002] For reusable dry cell batteries such as lithium-ion, nickel-metal hydride, and nickel-cadmium batteries, a charging case is usually required to charge them.

[0003] Existing charging cases can usually only be used independently, and each charging case can generally only be used with one type of battery. If multiple batteries need to be charged at the same time, multiple charging cases are required, and each charging case needs to be equipped with a power adapter. This results in a large number of power adapters and power cords, making the wiring messy, which is not conducive to desktop organization and also increases safety risks. Utility Model Content

[0004] To address the aforementioned issues, the primary objective of this invention is to provide a stackable charging box that requires only one power adapter to power all the charging boxes, thereby reducing the need for power adapters and facilitating desktop organization.

[0005] Another objective of this invention is to provide a stackable charging box that can reduce the number of power adapters and charging cables, thereby reducing safety hazards.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a stackable charging box, comprising:

[0008] The housing has a charging slot for accommodating a battery, and the charging slot has charging terminals that can be connected to the battery.

[0009] A control circuit board is disposed inside the box and connected to the charging terminal;

[0010] A power input interface is mounted on the housing and connected to the control circuit board.

[0011] A conductive component is disposed inside the housing and connected to the control circuit board;

[0012] The top of the box has a first docking structure, and the bottom of the box has a second docking structure. The upper end of the conductive element extends into the first docking structure, and the lower end of the conductive element extends into the second docking structure. When multiple boxes are stacked, the first docking structure and the second docking structure can be docked vertically, so that the lower end of the conductive element of the upper box can be electrically connected to the upper end of the conductive element of the adjacent lower box.

[0013] Furthermore, four conductive components are provided, and the four conductive components are respectively disposed on the four bottom corners of the box body. The top of each of the four bottom corners of the box body is provided with a first docking structure, and the bottom of each of the four bottom corners of the box body is provided with a second docking structure, so as to realize the installation of the four conductive components.

[0014] Furthermore, the first docking structure includes a groove formed on the top of the box body, and the second docking structure includes a protrusion formed on the bottom of the box body. The groove and the protrusion are adapted to each other in shape and are arranged vertically opposite each other. The groove has a first vertical through hole, and the protrusion has a second vertical through hole. The upper end of the conductive element extends out of the groove through the first vertical through hole, and the lower end of the conductive element is connected to the second vertical through hole. In this application, the upper end of the conductive element of the lower box body can pass through the first vertical through hole of the box body and then enter the second vertical through hole at the bottom of the upper box body, connecting with the lower end of the conductive element of the upper box body, thereby realizing the electrical connection between the upper and lower box bodies.

[0015] Furthermore, a guide post is provided at the lower end of the groove, the first through hole extends and penetrates the guide post, and the conductive element is inserted into the guide post.

[0016] Furthermore, the conductive component adopts a spring pin, the elastic extension end of which is located at one end of the groove, and can extend out of the groove from the first upper and lower through holes, and use elasticity to make electrical connection with the upper charging box, which can ensure the connection between the conductive components of the upper and lower charging boxes and improve the stability of power supply.

[0017] Furthermore, the housing includes an outer shell, an inner shell, and a cover plate. The inner shell is installed inside the outer shell, and the two are fixedly connected by snap-fit ​​fasteners. The cover plate is fixedly installed on the upper end of the inner shell, and the two are also fixedly connected by snap-fit ​​fasteners. The charging slot is disposed between the inner shell and the cover plate, and the control circuit board is disposed between the outer shell and the inner shell. The groove is formed on the top of the inner shell, and the protrusion is disposed on the bottom of the outer shell. This structural design allows for the separation of the control circuit board from the battery and facilitates the installation of the control circuit board and conductive components.

[0018] Furthermore, a positioning magnet is provided inside the inner shell. The upper end of the positioning magnet abuts against the inner wall of the top of the inner shell, and the lower end of the positioning magnet abuts against the inner wall of the bottom of the outer shell. When the upper and lower charging boxes are stacked, they can be positioned by the positioning magnet, thereby facilitating the alignment of the first docking structure and the second docking structure.

[0019] Furthermore, multiple positioning magnets are provided, located at the four bottom corners of the inner shell respectively.

[0020] Furthermore, the charging terminal includes a TYPE-C male connector, and the battery to be charged is provided with a TYPE-C female connector. The connection between the battery and the charging box is realized through the TYPE-C method, making charging more convenient.

[0021] Furthermore, the shape of the charging slot is compatible with one of the following battery types: AA, AAA, C, D, 9V, 18650, and CR123A.

[0022] Furthermore, the power input interface includes either a TYPE-C interface or a USB interface.

[0023] The beneficial effects of this utility model are as follows: Compared with the prior art, the charging box of this application has an independent charging function. When multiple charging boxes adapted to different battery models are stacked on top of each other, they can be docked and positioned through the first docking structure and the second docking structure of the box body. During docking and positioning, the conductive parts of the two adjacent layers of charging boxes can be connected to achieve conductivity between the multiple layers of charging boxes. Only one power adapter needs to be inserted into the power input interface of one of the charging boxes to connect the circuits of all charging boxes in parallel, so that the batteries in all charging boxes can be charged synchronously. This reduces the use of power adapter charging cables and facilitates desktop organization. At the same time, when the number of charging cables is reduced, there will be no mutual interference between the charging cables, which can reduce safety hazards. Attached Figure Description

During docking and positioning, the conductive parts 7 of the two adjacent layers of charging boxes 100 can be connected to achieve conductivity between the multiple layers of charging boxes 100. Only by inserting a power adapter into the power input interface 6 of one of the charging boxes 100, the circuits of all charging boxes 100 can be connected in parallel, and the batteries 2 in all charging boxes 100 can be charged synchronously. This reduces the use of power adapter charging cables and facilitates desktop organization.

[0043] Furthermore, the conductive element 7 is a spring pin, the elastic extension end of which is located at one end of the groove 81. It can extend out of the groove 81 from the first upper and lower through hole 82 and make an electrical connection with the upper charging box 100 using elasticity. This can ensure the stable connection between the conductive elements 7 of the upper and lower charging boxes 100 and improve the stability of power supply.

[0044] Furthermore, the housing 1 includes an outer shell 11, an inner shell 12, and a cover plate 13.

The above structure can both separate the control circuit board 5 from the battery 2 and facilitate the installation of the control circuit board 5 and the conductive component 7.

[0045] Furthermore, a positioning magnet 10 is provided inside the inner shell 12. The upper end of the positioning magnet 10 abuts against the inner wall of the top of the inner shell 12, and the lower end of the positioning magnet 10 abuts against the inner wall of the bottom of the outer shell 11. When the upper and lower charging boxes 100 are stacked, they can be positioned by the positioning magnet 10, thereby facilitating the alignment of the first docking structure 8 and the second docking structure 9.

[0046] Furthermore, multiple positioning magnets 10 are provided, located at the four bottom corners of the inner shell 12 respectively.

[0047] Furthermore, the charging terminal 4 adopts a TYPE-C male connector, and the battery 2 that needs to be charged is provided with a TYPE-C female connector. The connection between the battery 2 and the charging box 100 is realized through the TYPE-C method, making charging more convenient.
