Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] In this embodiment of the invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 12 , Figure 13 , Figure 16 and Figure 17As shown in the embodiment of this application, a charging device 1 is provided. The charging device 1 may be, for example, a charger with foldable plugs, the plugs having a retracted state and an extended state. The charging device 1 also includes a charging module, etc. The charging device 1 includes a main housing 60, a plug module 10, and a conductive spring 40. The main housing 60 has a receiving cavity 64, in which the charging module is disposed. A positioning mounting part is provided on the inner wall of the main housing 60, and a plug mounting groove is provided in the positioning mounting part. The plug module 10 includes a positioning module 21 and a plug assembly 20. The positioning module 21 is located in the receiving cavity 64 and connected to the positioning mounting part. The plug assembly 20 is installed between the plug mounting groove and the positioning module 21. The conductive spring 40 is installed on the positioning module 21, and the conductive spring 40 is electrically connected to the charging module and the plug assembly 20, respectively.

[0042] Specifically, the positioning module 21 includes a positioning base 30, a conductive spring 40, and a mounting base 50. The conductive spring 40 is sandwiched between the positioning base 30 and the mounting base 50 and is fixed to the positioning base 30. By sandwiching the conductive spring 40 between the positioning base 30 and the mounting base 50, the positioning module 21 is pre-assembled, achieving pre-installation of the conductive spring 40 and forming a pre-installation module, which allows for quick installation of the positioning module 21. First, the pin assembly 20 is placed in the pin mounting slot, and then the pre-assembled positioning module 21 is placed in the positioning mounting part. The positioning module 21 positions the pin assembly 20 to achieve electrical connection between the positioning module 21 and the pin assembly 20. At the same time, the pin assembly 20 is positioned between the pin mounting slot and the positioning module 21, achieving a fixed or rotatable connection with the main housing 60.

[0043] The modular design allows the positioning module 21 to be pre-assembled at an independent workstation, facilitating precise positioning of the conductive spring 40 and the pin assembly 20. This effectively reduces assembly errors, ensures the stability of the electrical connection between the pin assembly 20 and the conductive spring 40, and improves production efficiency. Secondly, the pin assembly 20 and positioning module 21 are placed as a whole within the receiving cavity 64 of the main housing 60, and positioned in the pin mounting slot and positioning mounting part. This allows for a fixed or rotatable connection between the pin assembly 20 and the main housing 60 without disassembling the housing. This avoids gaps between the independent pin housing and the main housing 60, ensuring the integrity and visual uniformity of the main housing 60's appearance, preventing a rough texture caused by gaps, strengthening the overall structural strength of the housing, improving the equipment's resistance to impact and compression, extending product lifespan, and effectively improving the user's perception of product quality.

[0044] Reference Figure 1 , Figure 2 , Figure 12 and Figure 13As shown in the embodiments of this application, the main housing 60 includes a bottom housing 61, a top housing 62, and a side housing 63 connecting the bottom housing 61 and the top housing 62.

The pin assembly 20 is fixed to the side housing 63 through the pin mounting groove, and the positioning module 21 is fixed to the side housing 63 through the positioning mounting part. The housing corresponding to the pin 201 does not need to be disassembled. The integrally formed bottom housing 61 and side housing 63 have no splicing gaps, which effectively improves the overall structural strength and provides more stable support for the pin module 10.

[0045] Reference Figure 6 , Figure 7 , Figure 8 and Figure 15 As shown in the embodiment of this application, the pin assembly 20 includes a rotating shaft 203 and two pins 201, with the two pins 201 respectively fixedly connected to the rotating shaft 203.

The positioning module 21 is detachably connected to the positioning mounting part, and the rotating shaft 203 is rotatably connected between the rotating shaft groove 634 and the rotating shaft receiving groove 302. The pin assembly 20 is disposed in the pin mounting groove, and the positioning module 21 is disposed in the positioning mounting part, so that the pin assembly 20 is located between the pin mounting groove and the positioning module 21, realizing the rotatable connection between the pin assembly 20 and the main housing 60. The rotating shaft 203 is confined between the rotating shaft groove 634 and the rotating shaft receiving groove 302, providing sufficient rotation space for the rotation of the pin assembly 20. Meanwhile, the multiple connections ensure that the pin assembly 20 will not easily fall off or shift during rotation, enhancing the overall stability and safety of the product.

[0046] Reference Figure 4 , Figure 5 , Figure 9 and Figure 17 As shown in the embodiment of this application, the positioning module 21 includes a positioning seat 30 and a mounting seat 50. One end of the conductive spring 40 is at least partially clamped between the positioning seat 30 and the mounting seat 50, and the other end of the conductive spring 40 is bent toward the direction of the pin module 10 to form a spring arm 402. By fixing the conductive spring 40 with the positioning seat 30 and the mounting seat 50, a pre-installation of the conductive spring 40 is formed, which can realize independent pre-assembly and testing before overall assembly, reduce the operation steps in the final assembly process, and improve the assembly efficiency on the production line.

[0047] In one embodiment of this invention, the positioning base 30 may be provided with a plurality of protruding first positioning posts 301, which are located on the side of the positioning base 30 facing the mounting base 50.

The positioning seat 30 is also provided with a second screw hole 307, and the mounting seat 50 is also provided with a first screw hole 505. The first screw hole 505 and the second screw hole 307 are correspondingly provided. When the mounting seat 50 is connected to the positioning seat 30, the screws are fixed in the first screw hole 505 and the second screw hole 307, further strengthening the connection between the mounting seat 50 and the positioning seat 30. The positioning seat 30 is provided with a rotating shaft receiving groove 302 on the side away from the mounting seat 50. When the pin assembly 20 is provided in the pin mounting groove and the positioning module 21 is provided in the positioning mounting part, the pin assembly 20 is limited to the rotating shaft receiving groove 302. Of course, the positioning seat 30, the mounting seat 50, and the conductive spring 40 can also be fixedly connected in other ways, and this embodiment is not limited to this. The synergistic effect of multiple positioning structures can strictly control the assembly accuracy of the positioning seat 30, the conductive spring 40, and the mounting seat 50, ensuring the uniformity of the positions of each component in mass production, reducing electrical connection problems caused by assembly deviations, and improving product consistency.

The positioning mounting portion is provided with a second stop portion 631 that cooperates with the first stop portion 304, and a second locking portion 612 that cooperates with the first locking portion 308.

[0050] For example, the first stop 304 and the first locking part 308 are disposed on the positioning seat 30, and the second stop 631 and the second locking part 612 are disposed on the side shell 63. When the positioning module 21 is disposed in the positioning mounting part, the second stop 631, the first stop 304, the first locking part 308 and the second locking part 612 fix the positioning module 21 to the main shell 60, providing a clear positioning reference for the installation of the positioning module 21 in the receiving cavity 64, ensuring that the positioning module 21 is quickly and accurately aligned, and avoiding misalignment during assembly.

[0052] The first stop 304 and the second stop 631 are fixed together by a stop groove and a stop block snap fastener. The first locking part 308 and the second locking part 612 are correspondingly connected by screws. Multiple connection methods are used to improve the fixing effect between the positioning module 21 and the main housing 60. Different combinations of fixing methods can be used according to the specific design.

[0053] Secondly, the bottom shell 61 is provided with a plurality of support ribs 611 on the side near the side shell 63. The plurality of support ribs 611 are spaced apart and extend in a direction away from the bottom shell 61. When the positioning module 21 is located in the positioning mounting part, the plurality of support ribs 611 abut against the positioning module 21 to provide auxiliary support for the positioning module 21 and prevent the second stop part 631 and the first stop part 304, the first locking part 308 and the second locking part 612 from becoming loose.

The positioning protrusion 305 of the positioning seat 30 and the positioning groove 632 on the inner wall of the side shell 63 form a limiting engagement, restricting the displacement of the positioning module 21 within the main housing 60, and further providing a clear positioning reference for the installation of the positioning module 21 on the side shell 63.

[0056] Reference Figure 12 , Figure 13 and Figure 15 As shown in the embodiment of this application, the pin mounting groove includes a pivot groove 634, a pin positioning groove 635, and two pin storage grooves 633 communicating with the receiving cavity 64.

[0065] Specifically, the mounting base 50 has an extension wall 506 on the side away from the baffle 502, extending from the mounting base 50 towards the positioning base 30. The mounting base 50 has a limiting groove 507 on the side facing the positioning base 30. When the pin assembly 20 is located in the pin mounting groove and the positioning module 21 is located in the positioning mounting part, the rotating shaft 203 is located in the rotating shaft receiving groove 302, and the positioning part 202 is located in the limiting groove 507. The baffle 502 is located between the positioning part 202 and the first wire 11 and the second wire 12, preventing direct contact between the wires and the positioning part 202, preventing sparks from the wires and the electrical connection part 2011, reducing safety hazards such as short circuits and leakage, and improving the safety of the charging device 1.

[0066] Secondly, the mounting base 50 is provided with a wire positioning part 503, which is located on the same side of the mounting base 50 as the baffle 502. The wire positioning part 503 extends from the mounting base 50 toward the positioning base 30; or, the wire positioning part 503 is located on the baffle 502, and the first wire 11 or the second wire 12 is located within the wire positioning part 503. This confines the wire within the wire positioning part 503, forming a clear wiring path and preventing the wire from shifting or tangling due to equipment vibration, pin 201 rotation, etc., thus ensuring orderly wiring inside the charging device 1.

[0067] Reference Figure 14 , Figure 15 and Figure 16 As shown in the embodiment of this application, the top shell 62 is provided with a baffle 622, which is located on the side of the top shell 62 facing the receiving cavity 64 and protrudes from the top shell 62. When the pin module 10 is located in the receiving cavity 64, the baffle 622 is located on the side of the positioning module 21 away from the pin assembly 20. The baffle 622 is located on the side of the mounting base 50 away from the pin 201, and the baffle 622 can reliably limit the mounting base 50, preventing the pin module 10 from shifting in the receiving cavity 64 and ensuring the overall assembly stability.

[0068] Reference Figure 14 , Figure 15 and Figure 16 As shown in the embodiment of this application, the top shell 62 is provided with a surrounding wall 621 on its side. The surrounding wall 621 is located on the side of the top shell 62 facing the receiving cavity 64 and extends toward the receiving cavity 64. The baffle 622 is vertically connected to the surrounding wall 621 and extends away from the surrounding wall 621.

[0069] The side wall 621 of the top shell 62 extends toward the receiving cavity 64, significantly increasing the contact area between the top shell 62 and the bottom shell 61 and side shell 63. The baffle 622 is perpendicularly connected to the side wall 621 and extends away from the side wall 621. The side wall 621 provides a stable support foundation for the baffle 622, effectively dispersing the external force on the baffle 622 and preventing the baffle 622 from bending or deforming due to independent force.

[0070] Reference Figure 1 , Figure 12 and Figure 15 As shown in the embodiments of this application, the main housing 60 further includes a first shell 65 and a second shell 66. The first shell 65 is disposed on the top shell 62, and the second shell 66 is disposed on the bottom shell 61. The first shell 65 covers the top shell 62, and the second shell 66 covers the bottom shell 61, forming a double-layer protective structure, which can significantly enhance the impact and compression resistance of the main housing 60 and prevent the top shell 62 and bottom shell 61 from being directly damaged when the equipment is accidentally dropped or subjected to pressure.

[0071] In summary, the assembly process of the charging device 1 in this embodiment is as follows: The positioning module 21 is pre-assembled. First, the plug assembly 20 is laterally inserted into the integrally formed main housing 60 and positioned within the plug mounting slot. Then, the positioning module 21 is laterally inserted into the main housing 60 and positioned within the positioning mounting section. The positioning module 21 positions the plug assembly 20, at which point the plug assembly 20 is located between the plug mounting slot and the positioning module 21. Simultaneously, the positioning module 21 is fixed to the side shell 63 by structures such as the second stop 631, the first stop 304, and the plug positioning slot 635. The charging module is then inserted, and finally, the top shell 62 is encapsulated.
