[0033] Figure 1 Schematically shows a socket strip device according to the present invention, and the socket strip device is in the working mode of the extended position. In this embodiment, the socket strip device is installed in the horizontal desktop A and is in the working mode of the extended position. Of course, the socket strip device can also be installed on a vertical wall surface, or even on a workbench surface at any other inclined angle. The socket strip device mainly includes a socket strip 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 strip device 1 is connected to the electric wire led out from the hole.

[0034] Figure 2 Schematically shows an exploded view of the socket strip device of the socket strip device according to the present invention. The socket strip 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 receiving shell. The lower housing 12 plugged with the multi-socket power-taking module assembly 13 is detachably connected to the upper receiving shell by self-tapping screws to encapsulate the multi-socket power-taking module assembly.

[0035] The multi-socket power-taking module assembly 13 includes a plurality of strong power-taking modules and a USB interface module. The strong power-taking module can be selected from one or more of a national standard strong power module, a Korean standard / German standard strong power module, a European and American standard strong power module, and a multi-national standard strong power module. The USB interface has an A+C interface. Thus, a variety of application options are provided for users.

[0036] 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. 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 62 that is inclined upward relative to the head by an inclination angle that can be between 30 - 40 degrees. At a position on the lower surface of the horn-shaped head 61 near the jaw 62, there are two opposite downward protruding lugs 63 (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 and the torsion spring 65 located between the opposite lugs 63 and below the spring holding portion of the cover 4 from below the cover 4 to detachably connect the torsion spring 65 and the bracket 6 to the cover 4, thereby forming a cover assembly. There is also a corresponding spring receiving portion 67 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 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 by 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.

[0037] 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 accommodation shell using self-tapping screws.

[0038] Thus, the cover assembly, the wireless charger module 15, the upper housing 11, the multi-socket power-taking module assembly 13, and the lower housing 12 are assembled together to form the socket device 1.

[0039] See Figure 3 , the relative position switching device includes a position holding mechanism and a position switching structure.

[0040] 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 20. Oppositely arranged receiving brackets 32 are provided on the inner surface of the barrel 20. The receiving bracket 32 is 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 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 the convex holding part and the concave holding part.

[0041] See Figure 3 , a cylindrical guide tube is provided at the center of the barrel 20. A pair of opposite parallel guide rails 22 are provided on the inner surface of the guide tube. A limiting part 23 is provided on each guide rail at a limiting distance from the upper surface of the barrel 20. A spring 36 is placed in the guide tube.

[0042] See Figure 3 , the position switching mechanism is in the form of a sliding pin 24 in this embodiment. The sliding pin has a cylindrical body and two legs 29. A stop part 30 is provided on the outer side of the legs and is used to engage with the limiting part 23 provided on the guide rail. A pair of lower engaging parts are provided on the top section of the side surface of the body. Correspondingly, a pair of upper engaging parts are provided in the central tube at the center of the lower housing. The lower engaging parts are engaged with the upper engaging parts.

[0043] In Figure 3 the shown embodiment, the lower engaging part is a J-shaped guide groove including a vertical guide part 28 and a horizontal locking part 25, and the upper engaging part is a protruding part 33. The cross-section of the protruding part matches the cross-section of the J-shaped guide groove, so that the protruding part 33 can move in the J-shaped guide groove.

[0044] Figure 4 It schematically shows the pressed position L (shown by the dotted line) and the popped-up position R (shown by the solid line) of the sliding pin 24. When the sliding pin 24 is in the pressed position L, the socket device 1 is in the flush position working mode; when the sliding pin 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 raised distance of the socket device 1 rising from the installation box body 2 in the raised position working mode. The raised distance enables the multi-socket power-taking module assembly to be exposed from the installation box body to ensure normal power-taking operation.

[0045] Refer to as Figure 3, describe the installation process of the sliding pin 24. During installation, press the spring 36 and insert it into the guide rail 22, then insert the sliding pin 24 into the rail 22 and introduce it inward along the rail, so that the stop 30 reaches at least below the limit part 23 of the guide rail 22, and then release the sliding pin 24. Under the action of the spring 36, the sliding pin moves back, so that the stop 30 can engage with the limit part 23. Thus, the spring-driven sliding pin 24 is installed in place and in the raised position R.

[0046] Refer to Figure 3 , introduce the protrusion 33 in the lower housing of the assembled socket device into the vertical guiding part 28 of the J-shaped guiding groove, and then rotate clockwise by a rotation angle (the rotation angle is, for example, 3 - 6 degrees), so that the protrusion 33 enters the horizontal locking part 25 and remains locked in place. Thus, the socket device switches from the removed position working mode to the raised position working mode. Conversely, when switching the socket device 1 from the raised position working mode to the removed position working mode, just rotate the socket device counterclockwise by this rotation angle, so that the protrusion 33 moves out of the horizontal locking part 25 and enters the vertical guiding part 28 of the J-shaped guiding groove, and then pull it outwards, so that the protrusion 33 disengages from the vertical guiding part 28. Thus, the socket device 1 will be in the removed position working mode. In the removed position working mode, the socket device is removed from the installation box body and used as a mobile socket.

[0047] The following describes the switching between the raised position working mode and the flush position working mode of the socket device 1. Press the cover assembly of the socket device 1, and the sliding pin 24 together with the socket device presses the spring 36 and moves along the rail into the guiding cylinder until the closer 26 engages with a pair of upper position retaining parts provided on the lower surface of the cover 4, so that the socket device 1 is held in the flush position working mode. At this time, the socket device switches from the raised position working mode to the flush position working mode. Conversely, first press the cover assembly of the socket device 1 downward by hand, and then let go. With a "click" sound, the upper position retaining part and the closer 26 are disengaged, and the sliding pin 24 moves back along the rail under the elastic force of the spring until the stop 30 engages with the limit part 23 (that is, the sliding pin reaches the raised position R), thereby switching the socket device 1 from the flush position working mode to the raised position working mode. In the raised position working mode, the socket device 1 rises from the installation box body 2 by a rising distance, so that the multi-socket power-taking module assembly is exposed for the user to take power according to needs.

[0048] In an alternative embodiment (not shown), the lower engaging portion is an external thread provided on the upper side surface of the body, and the upper engaging portion is an internal thread provided on the inner surface of the central tube, and the external thread of the lower engaging portion is rotationally engaged with the internal thread of the upper engaging portion. The screwing and disconnecting of the threads can realize the switching between the moving out position working mode and the raised position working mode. The switching between the flush position working mode and the raised position working mode can refer to the embodiment of the sliding pin with a J-shaped guide groove.

[0049] Therefore, the socket strip device according to the present invention can switch between multiple working modes through the relative position switching device without the aid of any tools, and has a compact structure, simple assembly and disassembly, and strong applicability.

[0050] The socket device according to the present invention has multiple working modes. The multiple working modes include a flush position working mode (or a first use state) (see Figure 6 ), raised position working mode (or second use state) (see Figure 7 ) and out of position working mode (or third use state) (see Figure 1 ). In the flush position working mode, the socket strip device 1 is located in the installation box body 2, and only the cover of the socket strip device is higher than the installation box body. In the elevated position working mode, the socket strip device is raised a certain distance from the installation box body for the user to draw power through the multi-socket power module assembly. In the elevated position working mode, the socket strip device can provide a variety of power supply options, because the multi-socket power module assembly can include at least three high-voltage modules and a USB interface module. In the removed position working mode, the socket strip device is removed from the installation box body and used as a mobile socket strip. Wireless charging can be performed in the flush position working mode, the elevated position working mode and the removed position working mode.

[0051] Figure 8 The schematic diagram shows the state of wireless charging of a mobile phone when the power strip is installed on a vertical wall. As shown in the figure, the bracket 6 is unfolded outward to firmly support and hold the mobile phone. The power strip can be installed on a work surface with any tilt angle. For example, when installed on a horizontal work surface, the bracket 6 can hold the device to be wirelessly charged to prevent it from being accidentally moved. When installed on a tilted work 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, IPAD, etc.
