[0032] In this embodiment, the housing 1 is used as the mounting structure for the telescopic bracket assembly 4 and the telescopic support frame 5. When a mobile phone with the charging coil located in the upper part needs to be wirelessly charged horizontally with its back against the wall, the telescopic support frame 5 is opened backward, so that the telescopic support frame 5 forms an angle with the back of the housing 1 for support. At this time, the telescopic support frame 5 does not need to be adjusted in length, and the telescopic bracket assembly 4 also does not need to be adjusted in length. Then, the mobile phone is placed horizontally on the telescopic bracket assembly 4 with its back against the charging coil 3 for wireless charging. If the charging coil inside the mobile phone is located in the lower part, the mobile phone can also be placed vertically with its back against the wall. Wireless charging is performed on the charging coil 3. When the phone with the charging coil at the top needs to be wirelessly charged while leaning back vertically, the telescopic support frame 5 is opened backward and then stretched to adjust its length. At the same time, the telescopic bracket assembly 4 is also stretched to raise the housing 1, which in turn raises the charging coil 3. The telescopic support frame 5 supports the housing 1 at a preset length and preset angle. At this time, the height of the charging coil 3 is the height of the phone when it is leaning back vertically. Then, the phone is placed vertically on the telescopic bracket assembly 4 and wirelessly charged while leaning back against the charging coil 3, which improves the functionality.

[0033] In summary, this convenient wireless charger effectively meets users' needs for both horizontal and vertical wireless charging of their phones, thus enhancing the functionality of the wireless charger.

[0034] In this embodiment, the housing 1 is provided with a first sliding groove 11, and one end of the telescopic bracket assembly 4 is received in the first sliding groove 11 and slidably connected to the groove wall of the first sliding groove 11; the first sliding groove 11 is used to provide a sliding space for the telescopic bracket assembly 4, so that the telescopic bracket assembly 4 can be extended or shortened relative to the housing 1.

[0035] In this embodiment, a flexible engaging portion 12 is provided on one side of the housing 1. One end of the flexible engaging portion 12 extends into the first sliding groove 11 and forms an elastic engagement connection with one side of the telescopic bracket assembly 4. When the telescopic bracket assembly 4 is pulled out from the first sliding groove 11 relative to the housing 1, the flexible engaging portion 12 will abut against one side of the telescopic bracket assembly 4, so that the telescopic bracket assembly 4 is maintained in the pulled-out position, thereby changing the length of the telescopic bracket assembly 4 relative to the housing 1.

[0036] In this embodiment, the elastic engaging portion 12 includes a engaging block 121 and an elastic element 122. The engaging block 121 is slidably connected to the housing 1. One end of the engaging block 121 extends into the first sliding groove 11 and forms an interlocking connection with one side of the telescopic bracket assembly 4. One end of the elastic element 122 is fixedly connected to the other end of the engaging block 121, and the other end of the elastic element 122 abuts against the housing 1. The elastic element 122 is used to provide elastic support for the engaging block 121 when the telescopic bracket assembly 4 needs to be relatively... When the housing 1 is pulled out, the locking block 121 can be manually pried open to slide backward. At this time, the locking block 121 compresses and stores force on the elastic element 122. When it is necessary to fix the telescopic bracket assembly 4 in the appropriate position after pulling out, the locking block 121 is released. At this time, the elastic element 122 rebounds and pushes the locking block 121 to slide towards one side of the telescopic bracket assembly 4, so that the locking block 121 and one side of the telescopic bracket assembly 4 form an interlocking connection to fix the telescopic bracket assembly 4.

[0037] In this embodiment, a rack side 411 is provided on one side of the telescopic bracket assembly 4, and a plug tooth 1211 is provided at one end of the snap-fit ​​block 121.

In order to ensure that the snap-fit ​​block 121 will not slip when fixing one side of the telescopic bracket assembly 4, the plug tooth 1211 is provided to cooperate with the rack side 411 to strengthen the fixing force.

[0038] In this embodiment, a second sliding groove 13 is provided on one side of the housing 1. The second sliding groove 13 is connected to the first sliding groove 11. A portion of the locking block 121 is housed in the second sliding groove 13. The elastic member 122 is housed in the second sliding groove 13 and abuts against the groove wall of the second sliding groove 13. The second sliding groove 13 provides a sliding space for the locking block 121. When the locking block 121 is manually pried backward, the locking block 121 slides backward in the second sliding groove 13 to compress the elastic member 122. After the locking block 121 is released, the locking block 121 slides forward in the second sliding groove 13.

[0039] In this embodiment, the telescopic bracket assembly 4 includes a sliding plate 41 and a support plate 42. A rack side 411 is disposed on one side of the sliding plate 41. One end of the sliding plate 41 is received in the first sliding groove 11 and slidably connected to the groove wall of the first sliding groove 11. One side of the sliding plate 41 forms an elastic engagement connection with the housing 1. The other end of the sliding plate 41 forms a tight rotational connection with one end of the support plate 42. The other end of the support plate 42 extends from one side of the housing 1 to the outside of the charging coil 3. When it is necessary to extend the telescopic bracket assembly 4, the support plate 42 is pulled so that the sliding plate 41 slides out from the first sliding groove 11. Then, the telescopic support frame 5 also needs to be adjusted by the same length so that the housing 1 is lifted, thereby lifting the charging coil 3. Then, the angle between the support plate 42 and the sliding plate 41 is adjusted so that the bottom of the support plate 42 is flush with the externally placed plane. At this time, a mobile phone can be placed on the support plate 42 for wireless charging.

[0040] In this embodiment, the bottom of the housing 1 is provided with a clearance groove 14, and the tray 42 passes through the clearance groove 14. When the sliding plate 41 is not extended and the tray 42 is retracted, a part of the tray 42 can be accommodated in the clearance groove 14 to reduce the external space occupied.

[0041] In this embodiment, one end of the tray 42 is provided with a placement end bracket 421, which protrudes from the charging coil 3. The placement end bracket 421 is used to provide a supporting structure for the mobile phone to improve the placement stability of the mobile phone.

[0042] In this embodiment, the telescopic support frame 5 includes a connecting frame 51, a telescopic plate 52, and a hand-tightening component 53. One end of the connecting frame 51 is rotatably connected to the back of the housing 1, and one end of the telescopic plate 52 is slidably connected to the connecting frame 51. The hand-tightening component 53 is threadedly connected to one side of the connecting frame 51 and abuts against one side of the telescopic plate 52. When adjusting the length of the telescopic support frame 5, the telescopic plate 52 is manually pulled so that it extends relative to the connecting frame 51. Then, the hand-tightening component 53 is turned, which abuts the telescopic plate 52 and fixes it in the appropriate extended position. Then, the connecting frame 51 is rotated at an angle so that there is an angle between the connecting frame 51 and the housing 1, so as to cooperate with the extended telescopic bracket assembly 4 for external support, so that the mobile phone can be wirelessly charged vertically with the backrest.

[0043] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
