[0032] Figure 1Schematically shown is a socket device according to the present invention, and the socket device is in the working mode of the extended position. In this embodiment, the socket device is installed in the horizontal desktop A and is in the working mode of the extended position. Of course, the socket device can also be installed on a vertical wall surface, or even on a workbench surface at any other inclined angle. The socket device mainly includes a socket device 1 and a mounting box body 2. The cylindrical mounting box body 2 is embedded in the desktop A, and the protruding edge 21 on the upper surface of the mounting box body is placed on the upper surface of the desktop and is detachably fixed by screws. Of course, the mounting box body can be fixed to the desktop by other means. At least one hole 40 (see Figure 7 ) is provided on the lower surface of the mounting box body 2, and the socket device 1 is connected to the electric wire led out from the hole.

[0033] Figure 2 Schematically shown is an exploded view of the socket device of the socket device according to the present invention. The socket device 1 includes a cover assembly, a wireless charger module 15, a multi-socket power-taking module assembly 13, and a two-piece housing, and the two-piece housing has an upper housing 11 and a lower housing 12. The multi-socket power-taking module assembly 13 is plugged into the two-piece housing. A recess 7 is provided in the upper surface of the upper housing 11, and the wireless charger module 15 is received in the recess 7. The cover assembly is arranged on the upper surface of the upper housing 11 for shielding the wireless charger module 3. The cover assembly and the upper housing 11 are detachably connected together by screws 8 to form an upper accommodation shell. The lower housing 12 plugged with the multi-socket power-taking module assembly 13 is detachably connected to the upper accommodation shell to encapsulate the multi-socket power-taking module assembly.

[0034] The multi-socket power-taking module assembly 13 includes a plurality of strong electricity power-taking modules and a USB interface module. The strong electricity power-taking module can be selected from one or more of a national standard strong electricity module, a Korean standard / German standard strong electricity module, a European and American standard strong electricity module, and a multi-national standard strong electricity module. The USB interface has an A+C interface. Thus, a variety of application options are provided for users.

[0035] The cover assembly includes an annular cover 4, a circular contact member 5, and a horn-shaped bracket 6. The cover 4 has a central circular hole 42 for installing the contact member 5 and a bracket mounting hole 43 for installing the bracket 6. The contact member 5 is made of a non-metallic material and is plugged into the central circular hole 42 of the cover 4 for covering the wireless charger module 3, and moreover, the wireless charging device P is to be placed on the upper surface of the contact member 5 (see Figure 8 ). The bracket 6 includes a horn-shaped head 61 and a jaw portion 62 that is inclined upward by an inclination angle relative to the head, and the inclination angle can be between 30 and 40 degrees. Two opposite downward protruding lugs 63 are provided at a position on the lower surface of the horn-shaped head 61 close to the jaw portion 62 (see Figure 9). The bracket 6 is integrally formed by stamping. During assembly, the contact member 5 is inserted into the central circular hole 42, the bracket 6 is inserted into the bracket mounting hole 42 of the cover 4, and the pin shaft 66 passes through the hole 64 in the lug 63 from below the cover 4 and the torsion spring 65 located between the opposite lugs 63 and below the spring holding portion of the cover 4, thereby detachably connecting the torsion spring 65 and the bracket 6 to the cover 4, thus forming a cover assembly (refer to Figure 9 ). A corresponding spring receiving portion 67 is also provided on the upper housing 11. The assembled cover assembly and the upper housing 11 equipped with the wireless charger module are detachably connected together by screws 8. Among them, one free leg of the torsion spring 65 abuts against the jaw portion 62 of the bracket, and the other free leg abuts against the spring receiving portion 67 of the upper housing 11. Under the action of the torsion spring 65, the bracket 6 can be switched between a flat state and an outwardly expanded state. In the flat state, the horn-shaped head 61 of the bracket fits flush with the contact member 5 on the cover 4. In the outwardly expanded state, the horn-shaped head 61 expands outward at an inclination angle relative to the contact member 5, providing a space for accommodating a device to be wirelessly charged (such as a mobile phone). Due to the elasticity of the torsion spring providing sufficient clamping force, the bracket 6 can firmly hold the device to be wirelessly charged placed on the contact member 5 in the outwardly expanded state (see Figure 8 ) for wireless charging. The horn shape of the bracket increases the distance of the force application points for supporting the device to be wirelessly charged, and more firmly holds the device to be wirelessly charged. After removing the device to be wirelessly charged, under the action of the spring force, the horn-shaped head 61 automatically returns to the flat state flush with the contact member 5.

[0036] At least three strong power power-taking modules and a USB interface module are electrically connected to form a multi-socket power-taking module assembly 13. Then, the multi-socket power-taking module assembly 13 is inserted into the lower housing 12 and assembled together, and the assembled multi-socket power-taking module assembly 13 and the lower housing 12 are connected to the upper receiving housing by self-tapping screws. Optionally, a hub 9 for winding the built-in wire can be provided at the center position of the bottom surface of the lower housing. The length of the built-in wire determines the maximum retractable range when the socket device is in the retracted position working mode. The wire can be equipped with a length according to the requirements of the application scenario, such as 0.5 - 1.5 meters.

[0037] Thus, the cover assembly, the wireless charger module 15, the upper housing 11, the multi-socket power-taking module assembly 13, the lower housing 12, and the optional hub 9 are assembled together to form the socket device 1.

[0038] Refer to Figure 3 , the relative position switching device includes a three-point position holding mechanism and a position switching structure.

[0039] Figure 3It is an exploded view of the components installed in the installation box body. In this embodiment, the position holding mechanism includes a lower position holding part and an upper position holding part. The installation box body 2 is a cylindrical barrel body 20. Oppositely arranged receiving brackets 32 are provided on the inner surface of the barrel body 20. The receiving brackets 32 are used to receive the lower position holding part, which is the closer 26 in this embodiment. Figure 4 It shows that the closer 26 has been installed in the receiving bracket 32. The closer 26 is snap-connected to a pair of upper position holding parts (in the form of protruding parts) provided on the lower surface of the cover 4, and is used to hold the socket device 1 in the flush position working mode. The lower position holding part is one of a convex holding part and a concave holding part, and the upper position holding part is the other of a convex holding part and a concave holding part.

[0040] See Figure 3 , three guide rails 22 are further provided on the inner surface of the barrel body 20. The three guide rails 22 are arranged in parallel and spaced apart (according to specific applications, they can be equally spaced or non-equally spaced). Each guide rail is provided with a limiting part 23 at a limiting distance from the upper surface of the barrel body 20.

[0041] See Figure 3 , in this embodiment, the position switching mechanism is in the form of a sliding female buckle 24, which has a positioning hole 25, a release groove 28 and two legs 29. The positioning hole 25 is used to receive the protruding part 33 of the elastic male buckle provided on the lower outer surface of the lower housing 12 (see Figure 5 ). An outwardly protruding stop part 30 is provided at the end of the leg. During installation, the compression spring 36 is inserted into the guide rail 22, and the sliding female buckle 24 is inserted into the track and introduced inward along the track, so that the stop part 30 reaches at least below the limiting part 23 of the guide rail 22, and then the sliding female buckle 24 is released. Under the action of the spring 36, the sliding female buckle moves back, so that the stop part 30 can engage with the limiting part 23. Thus, the spring-driven sliding female buckle 24 is installed in place and is in the popped-up position R (see Figure 4 ).

[0042] Figure 4 It schematically shows the pressed-in position L (shown by the dotted line) and the popped-up position R (shown by the solid line) of the sliding female buckle 24. When the sliding female buckle 24 is in the pressed-in position L, the socket device 1 is in the flush position working mode; when the sliding female buckle 24 is in the popped-up position R, the socket device 1 is in the raised position working mode. The stop part 30 and the limiting part 23 cooperate to define the rising distance of the socket device 1 in the raised position working mode from the installation box body 2. The rising distance enables the multi-socket power-taking module assembly to protrude from the installation box body to ensure normal power-taking operation.

[0043] See Figure 3, the release groove 28 of the sliding female buckle is horizontally arranged relative to the leg 29 in the counterclockwise direction starting from the positioning hole 25. When the plug-in device 1 is rotated counterclockwise by a certain angle, the protruding part 33 of the elastic male buckle disengages from the positioning hole 25 of the sliding female buckle 24 along the release groove 28, and then the plug-in device 1 is taken out outward away from the mounting box body 2, so that the plug-in device 1 switches from the working mode in the raised position to the working mode in the removed position. The rotation angle is, for example, 3 - 6 degrees. Conversely, when the plug-in device 1 is switched from the working mode in the removed position to the working mode in the raised position, the protruding part 33 of the elastic male buckle is aligned with the release groove 28, and the plug-in device is rotated clockwise by this rotation angle, so that the protruding part 33 of the elastic male buckle engages with the positioning hole 25 of the sliding female buckle 24, and the plug-in device 1 will be in the working mode in the raised position.

[0044] The plug-in device according to the present invention has multiple working modes. The multiple working modes include a flush position working mode (or a first usage state) (see Figure 6 ), a raised position working mode (or a second usage state) (see Figure 7 ), and a removed position working mode (or a third usage state) (see Figure 1 ). In the flush position working mode, the plug-in device is located inside the mounting box body, and only the cover of the plug-in device is higher than the mounting box body. In the raised position working mode, the plug-in device rises a certain distance from the mounting box body for the user to take power through the multi-socket power-taking module assembly. In the raised position working mode, the plug-in device can provide multiple power-taking options because the multi-socket power-taking module assembly can include at least three strong power modules and a USB interface module. In the removed position working mode, the plug-in device is removed from the mounting box body and used as a mobile plug. In the three modes of the flush position working mode, the raised position working mode, and the removed position working mode, wireless charging can be performed.

[0045] Figure 8 A state diagram schematically showing wireless charging of a mobile phone when the plug-in device is installed on a vertical wall is shown. As shown in the figure, the bracket 6 expands outward to firmly support and hold the mobile phone P. The plug-in device can be installed on a workbench surface at any inclined angle. For example, when installed on a horizontal workbench surface, the bracket 6 can hold the device to be wirelessly charged and prevent it from being accidentally moved. When installed on an inclined workbench surface with a certain angle, the bracket 6 can play a dual role of holding and supporting. The device to be wirelessly charged can include a mobile phone, an IPAD, etc.

[0046] The switching between the multiple working modes of the plug-in device according to the present invention is achieved through a relative position switching device. The relative position switching device includes a position switching mechanism and a position holding mechanism. The following refers to the attached Figure 3to describe the switching between various working modes. In the flush position working mode, the sliding female buckle 24 is located at the bottom part of the mounting box body 1 (see the position marked by L in Figure 4 ), and in the raised position working mode, the sliding female buckle 24 is located at the top part of the mounting box body (see the position marked by R in Figure 4 ). After the positioning hole 25 of the sliding female buckle and the protruding part 33 of the elastic male buckle are engaged, press the cover assembly 4 of the socket strip device 1, and the sliding female buckle 24 together with the socket strip device moves downward along the guide rail 22 against the spring force until the upper position holding part and the lower position holding part are elastically engaged to hold the socket strip device in the flush position working mode, thereby switching the socket strip device 1 from the raised position working mode to the flush position working mode. Conversely, first press the cover assembly 4 of the socket strip device 1 by hand, and then release it. With a "click" sound, the upper position holding part and the lower position holding part are disengaged, and the sliding female buckle 24 moves upward along the track under the elastic force of the spring until the stopping part 30 engages with the limiting part 23, thereby switching the socket strip device 1 from the flush position working mode to the raised position working mode. In the raised position working mode, the distance that the socket strip device 1 rises from the mounting box body 2 makes the multi-socket power-taking module assembly exposed for the user to take power according to needs.

[0047] From the raised position working mode, when the socket strip device 1 is rotated counterclockwise by a rotation angle, the protruding part 33 of the elastic male buckle disengages from the positioning hole 25 of the sliding female buckle 24 along the release groove 28, and then the socket strip device 1 is taken out outward away from the mounting box body 2, so that the socket strip device 1 is switched from the raised position working mode to the removed position working mode. In the removed position working mode, the socket strip device is removed from the mounting box body and used as a mobile socket strip. According to specific application requirements, an appropriate length of wire is released from the hub for use. Conversely, insert the protruding part 33 of the elastic male buckle into the release groove 28 of the sliding female buckle 24, and rotate the socket strip device 1 clockwise by a rotation angle so that the protruding part 33 engages with the positioning hole 25 of the sliding female buckle 24, thereby switching the socket strip device 1 from the removed position working mode to the raised position working mode.

[0048] Thus, the socket strip device can be switched and used in multiple working modes without the aid of any tools, with a compact structure, simple disassembly and assembly, and strong applicability.

[0049] Although the specific embodiments of the present invention have been described in detail, those skilled in the art will recognize that various modifications and alternatives to these details can be developed based on the general teachings of the present invention. Therefore, the specific embodiments disclosed are only intended to illustrate rather than limit the scope of the present invention, and the scope of the present invention will be given by the full scope of the appended claims and any and all equivalents thereof.
