[0045] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] The present application is further described in detail below in conjunction with the accompanying drawings.

[0047] The embodiment of the present application discloses a wireless charging device.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, a wireless charging device includes a charging body 1, a rotating component 2 and a support member 3. An accommodating space is formed inside the charging body 1, and a connecting hole 15 is provided on one side of the charging body 1; the rotating component 2 is rotatably arranged in the accommodating space; the support member 3 is arranged on a side of the charging body 1 where the connecting hole 15 is provided; wherein the rotating component 2 is connected to the support member 3 through the connecting hole 15.

[0049] The rotating assembly 2 is disposed in the accommodating space. When the supporting member 3 is covered on the charging body 1, the rotating assembly 2 can be stored in the accommodating space, thereby reducing the overall space occupancy of the wireless charging device.

[0050] When the wireless charging device is needed, the rotating component 2 pushes the support member 3 to rotate together, and an angle is formed between the charging body 1 and the support member 3. The support member 3 is placed on the desktop. At this time, an inclined angle is formed between the charging body 1 and the desktop, which is convenient for the user to place the body 1 to be charged on the charging body 1 for charging.

[0051] As the support member 3 rotates with the rotating component 2, the portion of the rotating component 2 extending from the accommodating space increases as the rotation angle of the support member 3 increases, thereby avoiding the entire rotating component 2 being exposed to the outside and causing a waste of space, thereby solving the problem that existing wireless charging devices are large in size and occupy a large space.

[0052] Specifically, the charging body 1 is in the shape of a cube as a whole, and a side of the charging body 1 facing away from the supporting member 3 is a charging area for charging the component to be charged.

[0053] The support member 3 is in the shape of a rectangular support plate similar to the surface shape of the charging body 1 .

[0054] In order to ensure that sufficient complete space is reserved for the component to be charged, the rotating component 2 is located at one end of the charging body 1 , and one end of the supporting member 3 is arranged on the rotating component 2 .

[0055] A first avoidance groove 31 is provided on one side of the support member 3 facing the charging body 1 . The shape of the first avoidance groove 31 is a rectangle similar to the shape of the side of the support member 3 facing the charging body 1 .

[0056] The side of the support member 3 facing away from the charging body 1 is used to contact the ground to support the entire wireless charging device.

[0057] When the support member 3 rotates and stretches together with the rotating assembly 2, the support member 3 is supported in two ways: the support member 3 is placed flat on the desktop or the end of the support member 3 supports the desktop. When the end of the support member 3 supports the desktop, in order to achieve force balance, the ends of the charging body will be supported on the desktop together.

[0058] When the wireless charging device does not need to maintain a certain angle (ie, when the support member 3 does not need to provide support), the support member 3 can be folded toward the charging body 1 and abutted therewith to ensure the simplicity and convenience of holding the device.

[0059] The first avoidance groove 31 is provided so that there is a certain gap between the bottom of the first avoidance groove 31 and the surface of the charging body 1 after the support member 3 is turned over and covers the charging body 1, thereby reducing the contact area between the support member 3 and the charging body 1 and reducing the damage caused by the support member 3 to the surface of the charging body 1.

[0060] like Figure 1 , Figure 4 and Figure 6 As shown, the bottom of the first avoidance groove 31 includes a rotating surface 311 and a covering protection surface 312, and the rotating component 2 is arranged on the rotating surface 311;

[0061] The side of the charging body 1 facing the support 3 includes a rotation covering surface 111 and a protected surface 112 . The rotation covering surface 111 is used to be covered by the rotation surface 311 , and the protected surface 112 is used to be covered by the covering protection surface 312 .

[0062] Specifically, when the support member 3 is flipped over to cover the charging body 1 , the rotating surface 311 faces the rotating covering surface 111 , and the covering protection surface 312 faces the protected surface 112 , wherein the charging area is located within the protected surface 112 .

[0063] A second avoidance groove 11 is provided on one side of the charging body 1 facing the support member 3 , and a rotation covering surface 111 and a protected surface 112 are located at the bottom of the second avoidance groove 11 .

[0064] The second avoidance groove 11 is arranged opposite to the first avoidance groove 31. When the support member 3 is flipped over to cover the charging body 1, the gap between the support member 3 and the charging body 1 is increased, further preventing the support member 3 from directly contacting the charging body 1, and facilitating the avoidance of the subsequent support fixing member 222.

[0065] like Figure 1 and Fig. 9 As shown, the angle between the line from the connection point between the rotating component 2 and the support member 3 to the rotation center of the rotating component 2 and the protected surface 112 is greater than ninety degrees and less than one hundred and eighty degrees.

[0066] The rotating assembly 2 comprises:

[0067] A first hinge 21 is disposed in the accommodating space, and the first hinge 21 is close to one end of the charging body 1;

[0068] The second hinge 22 has one end hinged to the first hinge 21 and the other end extending out of the accommodating space and connected to the rotating surface 311;

[0069] The second hinge 22 rotates around the first hinge 21;

[0070] The angle between the line connecting the rotation center of the second hinge 22 and the support member 3 and the protected surface 112 is greater than ninety degrees and less than one hundred and eighty degrees.

[0071] Specifically, a rectangular accommodating space is formed inside the charging body 1, and the accommodating space is used to set the wireless charging device and the rotating component 2.

[0072] The rotating assembly 2 is disposed near the edge of the accommodating space, a portion of the rotating assembly 2 located in the accommodating space is located below the rotating cover surface 111 , and another portion of the rotating assembly 2 extends from the rotating cover surface 111 to be connected to the supporting member 3 .

[0073] One side of the first hinge 21 is fixedly connected to the inner wall of the charging body 1 , and the second hinge 22 is hinged to the first hinge 21 . The second hinge 22 can rotate around the hinged position with the first hinge 21 as the rotation center.

[0074] One end of the second hinge 22 passes through the connecting hole 15 and is connected to the rotating surface 311 .

[0075] When the support member 3 covers the charging body 1, the line connecting the rotation center of the second hinge 22 and the first hinge 21 and the connection position of the second hinge 22 and the support member 3 is the first line, and the angle between the first line and the protected surface 112 should be greater than 90 degrees and less than 180 degrees. This avoids the situation where the support member 3 is restricted by the upper surface of the charging body 1 when the support member 3 is flipped over from the charging body 1 and opened, and the self-locking phenomenon occurs, which causes the support member 3 to be unable to flip over or the flip angle is small and cannot be fully opened.

[0076] like Figure 7 and Figure 8 As shown, the first hinge 21 includes a first rotating member 211 and a fixing member 212, the first rotating member 211 is arranged on the fixing member 212, and the fixing member 212 is arranged to be screwed with the charging body 1;

[0077] The first rotating member 211 is provided with a rotating shaft 2111 , and the second hinge 22 is rotatably connected to the rotating shaft 2111 .

[0078] Specifically, the fixing member 212 is in the shape of a rectangular plate as a whole, a screw hole is provided on the upper surface of the fixing member 212, a fixing block is provided inside the accommodating space of the charging body 1, and the fixing member 212 is screwed to the fixing block through the screw hole.

[0079] Two first rotating members 211 are provided, and the two first rotating members 211 are respectively provided at two ends of the same side of the fixing member 212 .

[0080] The rotating shaft 2111 is disposed between the two first rotating members 211 .

[0081] One end of the second hinge 22 is passed through the rotating shaft 2111 and is rotatably connected to the rotating shaft 2111 .

[0082] like Figure 7 , Fig. 9 , Fig.10 and Fig.11 As shown, the second hinge 22 includes a rotating member 221, a first supporting connecting member 223, a second supporting connecting member 224 and a supporting fixing member 222. The rotating member 221 is rotatably connected to the rotating shaft 2111, and the supporting fixing member 222 is arranged on the rotating member 221. The supporting fixing member 222 is screwed to the supporting member 3.

[0083] One end of the first supporting connecting member 223 is perpendicularly arranged to one end of the second supporting connecting member 224 , and the other end is connected to the rotating member 221 . The other end of the second supporting connecting member 224 is arranged on the supporting fixing member 222 , and the second supporting connecting member 224 is perpendicularly arranged to the supporting member 3 .

[0084] Specifically, the first supporting connector 223 and the second supporting connector 224 are L-shaped as a whole, and the supporting fixing member 222 is shaped like a rectangular plate. In order to increase the stability of the connection between the second hinge 22 and the supporting member 3, one side plate surface of the supporting fixing member 222 is screwed to the rotating surface 311.

[0085] One end of the second supporting connecting member 224 facing away from the first supporting connecting member 223 is arranged perpendicularly to the supporting fixing member 222 , so that the first supporting connecting member 223 is arranged perpendicularly to the supporting member 3 .

[0086] The connection hole 15 is in the shape of a rectangular strip hole, and the second supporting connector 224 is inserted into the connection hole 15 .

[0087] The second supporting connector 224 will gradually extend out from the accommodating space as the supporting member 3 rotates.

[0088] Furthermore, a position avoidance hole is provided on the fixing plate, and the first supporting connector 223 passes through the position avoidance hole and is located below the rotation center. When the supporting member 3 is flipped over and covers the charging body 1, the first supporting connector 223 is arranged parallel to the upper surface of the charging body 1, and the second supporting connector 224 is arranged perpendicular to the upper surface of the charging body 1.

[0089] Therefore, when the support member 3 is turned over, the connection between the support member 3 and the second hinge 22 can be lifted to a higher position by the second hinge 22, so that the charging body 1 can be avoided during the turning process of the support member 3.

[0090] like Figure 5 , Figure 7 , Fig. 9 and Fig.11 As shown, a connecting protrusion 33 is provided at the middle of the rotating surface 311 , a fixing groove 331 is provided on one side of the connecting protrusion 33 covering the protective surface 312 , and the flip fixing member 212 is screwed to the bottom of the fixing groove 331 .

[0091] When the support member 3 covers the charging body 1 , the connection protrusion 33 may abut against the rotation covering surface 111 , thereby increasing the stability of the support member 3 when covering the charging body 1 .

[0092] like Fig. 9 and Fig.11 As shown, an angle limiter 12 is provided on the inner wall of the charging body 1 . The angle limiter 12 is provided on the rotation path of the second hinge 22 . The angle limiter 12 is used to limit the rotation angle of the second hinge 22 .

[0093] Specifically, the angle limiter 12 is arranged on the side of the charging body 1 located in the accommodating space close to the support member 3, and is located on the rotation path of the first support connecting member 223. The angle limiter 12 is provided with a fitting inclined surface. When the support member 3 is flipped in the opposite direction to open, the surface of the first support connecting member 223 will eventually abut against the surface of the fitting inclined surface, thereby preventing the support member 3 from continuing to rotate.

[0094] The provision of the angle limiter 12 prevents the support member 3 from over-turning so that the end of the support member 3 close to the rotation center may scratch the surface of the charging body 1 and cause damage to the charging body 1 .

[0095] The arrangement of the fitting inclined surface can increase the contact area between the angle limiting member 12 and the first supporting connecting member 223, thereby reducing stress concentration.

[0096] It should be noted that when the angle limiting member 12 is in contact with the first supporting connector 223 , the rotation angle between the supporting member 3 and the charging body 1 will reach the maximum rotation angle.

[0097] The maximum rotation angle ranges from 75 degrees to 45 degrees. In this embodiment, the maximum rotation angle is 70 degrees.

[0098] like Figure 1 , Figure 5 and Figure 6 As shown, a first auxiliary groove 14 is provided at one end of the charging body 1 away from the rotation position of the charging body 1 and the support member 3. The first auxiliary groove 14 is connected to the second avoidance groove 11, and the side of the first auxiliary groove 14 away from the second avoidance groove 11 is connected to the outside.

[0099] A second auxiliary groove 32 is provided at one end of the support member 3 away from the charging body 1 and the rotation position of the support member 3 , and the second auxiliary groove 32 is provided corresponding to the first auxiliary groove 14 .

[0100] Specifically, the first auxiliary groove 14 is disposed on the upper surface of the charging body 1 and communicates with the second avoidance groove 11. The second auxiliary groove 32 communicates with the first avoidance groove 31, and the side of the second auxiliary groove 32 away from the first avoidance groove 31 is also communicated with the outside.

[0101] When the support member 3 is flipped over to cover the charging body 1, the first auxiliary groove 14 and the second auxiliary groove 32 correspond to each other, and there is a gap on the side of the first auxiliary groove 14 and the second auxiliary groove 32 facing outward, which is convenient for the user to flip the support member 3 open and charge the charging body.

[0102] In summary, a wireless charging device includes a charging body 1, a rotating assembly 2 and a supporting member 3. An accommodating space is formed inside the charging body 1, and a connecting hole 15 is provided on one side of the charging body 1; the rotating assembly 2 is rotatably arranged in the accommodating space; the supporting member 3 is arranged on a side of the charging body 1 where the connecting hole 15 is provided; wherein the rotating assembly 2 passes through the connecting hole 15 and is connected to the supporting member 3;

[0103] A first avoidance groove 31 is provided on one side of the support member 3 facing the charging body 1. The bottom of the first avoidance groove 31 includes a rotating surface 311 and a covering protection surface 312. The rotating assembly 2 is arranged on the rotating surface 311.

[0104] The side of the charging body 1 facing the support member 3 includes a rotation covering surface 111 and a protected surface 112, the rotation covering surface 111 is used to be covered by the rotation surface 311, and the protected surface 112 is used to be covered by the covering protection surface 312;

[0105] The angle between the line from the connection point between the rotating component 2 and the support member 3 to the rotation center of the rotating component 2 and the protected surface 112 is greater than ninety degrees and less than one hundred and eighty degrees.

[0106] The rotating assembly 2 is disposed in the accommodating space. When the supporting member 3 is covered on the charging body 1, the rotating assembly 2 can be stored in the accommodating space, thereby reducing the overall space occupancy of the wireless charging device.

[0107] When the wireless charging device is needed, the rotating component 2 pushes the support member 3 to rotate together, and an angle is formed between the charging body 1 and the support member 3. The support member 3 is placed on the desktop. At this time, an inclined angle is formed between the charging body 1 and the desktop, which is convenient for the user to place the body 1 to be charged on the charging body 1 for charging.

[0108] As the support member 3 rotates with the rotating component 2, the portion of the rotating component 2 extending from the accommodating space increases as the rotation angle of the support member 3 increases, thereby avoiding the entire rotating component 2 being exposed to the outside and causing a waste of space, thereby solving the problem that existing wireless charging devices are large in size and occupy a large space.

[0109] At the same time, the first avoidance groove 31 is provided so that there is a certain gap between the bottom of the first avoidance groove 31 and the surface of the charging body 1 after the support member 3 is turned over and covers the charging body 1, thereby reducing the contact area between the support member 3 and the charging body 1 and reducing the damage caused by the support member 3 to the surface of the charging body 1.

[0110] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0111] It should be noted that the present invention takes a wireless charging device as an example to introduce the specific structure and working principle of the present invention, but the application of the present invention is not limited to a wireless charging device, and can also be applied to the production and use of other similar workpieces.

[0112] It should be understood that the present invention is not limited to the precise structure described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof.
