[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0028] Example 1, refer to Figures 1-5 As shown, a charging dock structure of this utility model includes,
[0029] The base 1 includes a base plate 11 and a support rib 12. The support rib 12 is provided on one end face of the base plate 11. Multiple positioning pins 13 are provided on the side of the support rib 12 away from the base plate 11. Multiple slots 111 are provided on the side of the base plate 11.
[0030] Terminal 2, multiple terminals 2 are provided and are respectively snapped into each slot 111;
[0031] The PCB board 3 has multiple insertion holes 31 that correspond to the positions of each positioning pin 13. The PCB board 3 is inserted into the positioning pin 13 through the insertion holes 31 and contacts the support rib 12. On the side of the PCB board 3 near the substrate 11, multiple spring pieces 32 that correspond to the positions of each terminal are connected. Each spring piece 32 is pressed between the PCB board 3 and each terminal 2.
[0032] Specifically, the support rib 12 supports the PCB board 3 and also enhances the strength of the entire base 1. The support rib 12 has a coverage area set according to the shape and size of the PCB board 3. The slots 111 are formed on the side of the substrate 11. The terminals 2 are perpendicular to the substrate 11 and are respectively snapped into the slots 111. The height of the end of the terminal 2 near the support rib 12 is lower than the height of the end face of the support rib 12. In this way, when the PCB board 3 is installed on the support rib 12, there is a certain space between the PCB board 3 and the ends of each terminal 2 to accommodate the spring piece 32. The spring piece 32, which is connected to the PCB board 3 at one end, is a bent plate structure formed by bending a rectangular plate twice. It is C-shaped in general. The spring piece 32 compressed between the PCB board 3 and the terminal 2 can make the end of the spring piece 32 away from the PCB board 3 in close contact with the terminal 2 through the elastic force. This connection method allows for quick connection between the PCB board 3 and each terminal 2 through a simple plug-in action, enabling rapid terminal switching. Installation and disassembly are very convenient, effectively improving the efficiency of charging dock production and maintenance.
[0033] The present invention provides a charging base structure that, by setting up a PCB board 3 with a spring sheet 32, in conjunction with a positioning pin 13 and a limiting structure, enables quick connection of the terminal 2, reduces the difficulty of installation and disassembly, and significantly improves efficiency.
[0034] Reference Figure 5 As shown, the slot 111 is a rectangular slot, and two parallel grooves 21 are symmetrically arranged on the side of each terminal 2. The distance between the bottom surfaces of the two grooves 21 matches the width of the slot 111, and the width of the groove 21 matches the thickness of the substrate 11. The terminal 2 is engaged in the slot 111 through the two grooves 21.
[0035] Reference Figure 4 As shown, the spring piece 32 is further a bent plate structure formed by bending a rectangular plate twice.
[0036] Furthermore, each of the spring pieces 32 has multiple through slots 321 extending along its length and spaced apart in its width. Specifically, by providing through slots 321 on the spring pieces 32, especially at bending points, stress concentration can be avoided, the service life of the spring pieces 32 can be extended, and local elasticity can be enhanced to stabilize contact pressure.
[0037] Reference Figure 3 As shown, further, two arc-shaped notches are symmetrically arranged on the PCB board 3, and two mutually symmetrical limiting protrusions 33 are arranged on the sidewalls of the two notches. The two limiting protrusions 33 divide the sidewalls of the two notches into four arc surfaces 34.
[0038] Reference Figure 2As shown, further, on the side of the substrate 11 where the supporting ribs 12 are provided, four arc-shaped limiting plates 14, each matching the shape of a circular arc surface 34, are vertically connected. Two limiting protrusions 33 are respectively engaged between two arc-shaped limiting plates 14. Specifically, when installing the PCB board 3, the arc surfaces of the four arc-shaped limiting plates 14 can guide the PCB board 3. Combined with the limiting effect of the two limiting protrusions 33 on the PCB board 3, this can help the operator quickly align the PCB board 3 with each positioning pin 13 to complete the rapid installation, while also ensuring the stability of the PCB board 3 after installation.
[0039] Furthermore, the shrapnel 32 is made of copper.
[0040] Furthermore, the PCB board 3 is provided with multiple PIN pins arranged in a matrix.
[0041] Furthermore, the free end of the positioning pin 13 is chamfered to facilitate insertion with the PCB board 3.
[0042] Specifically, during the assembly of the charging base, the terminal 2 is first inserted into the slots 111 through the grooves 21 provided on it. Then, the insertion hole 31 of the PCB board 3 is aligned with the positioning pin 13 and pressed down until the PCB board 3 contacts the support rib 12. During the pressing down of the PCB board 3, the spring pieces 32 at the bottom of the PCB board 3 are compressed between the end face of the PCB board 3 and the terminal 2 and are tightly attached to the terminal by the elastic force. When disassembling, the PCB board 3 can be pulled out directly.
[0043] Example 2: This utility model also discloses a charging system, including the charging base structure as in Example 1.
[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
