[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-10 A multifunctional charging plug shown includes a multi-model plug 1, which includes a charging plug housing 2, a protective top cover 3, a clamping block 4, a foldable plug 5, a wireless charging portion 6 and a telescopic wired interface 7. The top of the charging plug housing 2 is fixedly connected to one side of the clamping block 4, the wireless charging portion 6 is installed in the middle of the top of the charging plug housing 2, the protective top cover 3 is clamped on the top of the clamping block 4, the foldable plug 5 is rotatably connected to one side of the charging plug housing 2, and the telescopic wired interface 7 is slidably connected to the inside of the charging plug housing 2;

[0035] The charging plug housing 2 is used to protect the telescopic wired interface 7, which is used to connect various types of data connection cables. The protective top cover 3 is used to dock with the card block 4 and fully protect the charging end of the wireless charging part 6. The wireless charging part 6 is used to wirelessly charge the device to be charged. The foldable plug 5 can be freely folded and used to connect a two-phase socket or a three-phase socket.

[0036] This product is equipped with a wireless charging structure, that is, by placing the receiving coil on the back of the charging device such as a mobile phone on the glass support 9, ensuring that the receiving coil on the back of the mobile phone is aligned with the transmitting coil 10 in the sealing sleeve 8 and the distance is appropriate, so as to achieve efficient energy transmission, thereby completing wireless charging. The PC socket shell 17 of this product is a retractable structure, which can be retracted into the charging plug shell 2 when not in use, to prevent the various interfaces from being exposed to the outdoors for a long time and absorbing dust, thereby improving safety performance.

[0037] The wireless charging unit 6 includes a sealing sleeve 8, a glass support 9 and a transmitting coil 10. The transmitting coil 10 is installed inside the sealing sleeve 8. The glass support 9 is arranged at the upper end of the transmitting coil 10. The transmitting coil 10 is used to convert electrical energy into magnetic field energy.

[0038] When this product is in use, the transmitting coil 10 generates a changing magnetic field through high-frequency alternating current. By placing the receiving coil of the charging device on the glass support 9, the receiving coil will enter the magnetic field generated by the transmitting coil 10. When the magnetic flux in the receiving coil changes, an electromotive force will be generated in the receiving coil, and then a current will be generated. This current is then used by the device for charging, thereby completing the wireless charging effect of this product.

[0039] The foldable plug 5 includes a hinged ear plate 11, a rotating bracket 12, a three-phase plug 13 and a two-phase plug 14. The hinged ear plate 11 is fixedly connected to the inside of the charging plug housing 2, the inner side of the rotating bracket 12 is hinged to the middle of the hinged ear plate 11, and the three-phase plug 13 and the two-phase plug 14 are fixedly connected to the outside of the rotating bracket 12.

[0040] The connection between the ground wire plug of the three-phase plug 13 and the charging plug housing 2 is also provided with a silver-plated protrusion 15 and a slot 16 of matching size.

[0041] Different plugs can be selected according to different interfaces of the socket. When using a two-phase plug 14, the rotating bracket 12 can be bent, and the rotating bracket 12 can be rotated along the central axis of the hinged ear plate 11 and the plug end can be stored in the placement groove 35. When using a three-phase plug 13, the two-phase plug 14 can be folded in the same way. When waiting for use, the silver-plated protrusion 15 of the ground wire plug is pulled out from the inside of the slot 16, so that the product reaches a regular shape, which is convenient for carrying.

[0042] The retractable wired interface 7 includes a PC socket shell 17, a sliding frame 18, a rack seat 19, a Type-A interface 20, a Type-B interface 21 and a Type-C interface 22. The top of the PC socket shell 17 is fixedly connected to the bottom of the sliding frame 18, the rack seat 19 is fixedly connected to the inner side of the sliding frame 18, and the Type-A interface 20, Type-B interface 21 and Type-C interface 22 are symmetrically arranged on the inner side of the PC socket shell 17.

[0043] According to different charging connector models of the device, this product has multiple groups of Type-A interfaces 20, Type-B interfaces 21 and Type-C interfaces 22 on both sides, so as to facilitate use, and the PC socket shell 17 has a good touch texture and is beautiful, which improves the user experience.

[0044] The upper end of the sliding frame 18 is also provided with a rotating handle 23, a guide rod 24 and a locking gear 25. The rotating handle 23 is installed on the outside of the charging plug housing 2, one end of the guide rod 24 is fixedly connected to one side of the rotating handle 23, and the locking gear 25 is sleeved on the outside of the guide rod 24 and is used to engage the rack seat 19.

[0045] The upper end of the PC socket housing 17 is also provided with a foldable rolling shutter piece 26, a fixed slide rail 27, a positioning slider 28, a compression spring 29 and a telescopic rod 30. The foldable rolling shutter piece 26 is slidably connected to both sides of the charging plug housing 2 and is used to connect the positioning slider 28. The fixed slide rail 27 is fixedly connected to the inside of the charging plug housing 2. The positioning slider 28 is slidably connected to the inner side of the fixed slide rail 27. The two ends of the compression spring 29 are respectively fixedly connected to the positioning slider 28 and the opposite side surfaces of the charging plug housing 2. The telescopic rod 30 is installed on the inner side of the compression spring 29.

[0046] When using the telescopic wired interface 7, the outer rotating handle 23 can be rotated to drive the guide rod 24 and the locking gear 25 to rotate. Since the outer teeth of the locking gear 25 are engaged with the rack seat 19, under the gear transmission, the sliding frame 18 can drive the PV socket shell to extend out of the interior of the charging plug housing 2, and each interface is exposed to the outside, so that the user can select the charging interface according to the device model.

[0047] When the multi-model plug 1 is not in use, the PC socket shell 17 can be retracted into the interior. At this time, since the compression spring 29 inside the charging plug housing 2 is always in a compressed state, under the elastic support of the spring, the positioning slider 28 can push the foldable roller shutter piece 26 downward along the track surface of the fixed slide rail 27, thereby covering the outlet of the charging plug housing 2 to prevent dust from entering the interior.

[0048] A rotating handle 2 31 , a limiting plate 32 and a blocking blade 33 are also provided on one side of the charging plug housing 2. The rotating handle 2 31 is installed in the middle part of the outer side of the charging plug housing 2, the limiting plate 32 is fixedly connected to the inner side of the rotating handle 2 31 , and the blocking blade 33 is welded to the outer wall surface of the limiting plate 32 .

[0049] A heat dissipation groove 34 matching the size of the blocking blade 33 is also provided inside the charging plug housing 2 near the second rotating handle 31 .

[0050] When the use environment is high temperature, the second rotary handle 31 can be turned to control the blocking blade 33 to rotate until the heat dissipation groove 34 is exposed to the outside, thereby enhancing the heat dissipation effect and extending the service life of the plug.

[0051] Working principle: When this product is in use, the transmitting coil 10 generates a changing magnetic field through high-frequency alternating current. By placing the receiving coil of the charging device on the glass support 9, the receiving coil will enter the magnetic field generated by the transmitting coil 10. When the magnetic flux in the receiving coil changes, an electromotive force will be generated in the receiving coil, and then a current will be generated. This current is then used by the device to charge, thereby completing the wireless charging effect of this product. Different plugs can be selected according to different interfaces of the socket. When using a two-phase plug 14, the rotating bracket 12 can be bent, and the rotating bracket 12 can be rotated along the central axis of the hinged ear plate 11 and the plug end can be stored in the placement groove 35. When using a three-phase plug 13, the two-phase plug 14 can be folded in the same way. When it is ready for use, the silver-plated protrusion 15 of the ground plug is pulled out from the inside of the slot 16, so that this product has a regular shape, which is easy to carry. According to the different charging connector models of the equipment, this product has multiple groups of Type-A interfaces 20, Type-B interfaces 21 and Type-C interfaces 22 on both sides, which is convenient for use, and the PC socket shell 17 has a good touch texture and is beautiful, which improves the user experience; when the multi-model plug 1 is not in use, the PC socket shell 17 can be retracted into the interior. At this time, since the compression spring 29 inside the charging plug shell 2 is always in a compressed state, under the elastic support of the spring, the positioning slider 28 can push the folding roller shutter piece 26 downward along the track surface of the fixed slide rail 27, thereby covering the outlet of the charging plug shell 2 to prevent dust from entering the inside.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
