A countersunk hole is provided on one side of the heat sink, and a magnetic wireless charging device is installed in the countersunk hole. A heat dissipation matrix column is provided on the other side of the heat sink. The heat dissipation matrix column and the countersunk hole are staggered, and both sides of the support cover extend upward to form a receiving groove compatible with the heat dissipation matrix column. The utility model is provided with a heat dissipation matrix column on the rear side of the heat sink, which can quickly and effectively dissipate the high temperature generated during the charging process and reduce the adverse effects caused by the high temperature.

[0035] Reference Figure 1 - Figure 3 The heat dissipation assembly 7 also includes a rotating plate 72 for driving the heat dissipation fan 73 to rotate. The bottom end of the rotating plate 72 is hinged to the top of the support plate 1. The heat dissipation fan 73 can be driven to rotate to adjust the blowing angle by rotating the rotating plate 72. The top of the rotating plate 72 is equipped with a heat dissipation fan 73 for assisting the heat dissipation of the mobile phone. The heat dissipation assembly 7 also includes a driving wheel 75 for driving the rack 76 to move. The left end of the driving wheel 75 is fixedly connected to the right end of the damping shaft 4. The damping shaft 4 can be driven to rotate by rotating the support plate 1. When the damping shaft 4 rotates, the driving wheel 75 will be driven to rotate. The right end of the rotating plate 72 is fixedly connected to a driving wheel 75 for driving the rotating plate 72 to rotate. The inner wall of the support plate 1 is slidably connected with a rack 76 for connecting the driving wheel 75 and the driven wheel 74. The rack 76 and the driving wheel 75 mesh with each other.

[0036] Reference Figure 1 - Figure 3The support assembly 6 includes a storage groove 68 for accommodating a rotating block 66 and a pressing block 65. The storage groove 68 is arranged at the top end of the support plate 1. The inner wall of the storage groove 68 is rotatably connected with a rotating block 66 for supporting the mobile phone. The left end of the rotating block 66 is fixedly connected with a support shaft 61 for supporting the rotation of the rotating block 66. There are multiple groups of rotating blocks 66. By setting two groups of rotating blocks 66, both sides of the bottom of the mobile phone can be supported at the same time when in use to keep the mobile phone stable. The multiple groups of rotating blocks 66 are symmetrically arranged with the center line of the support plate 1 as the symmetry axis. The left end of the support shaft 61 is fixedly connected to the right end of the other group of rotating blocks 66. The two groups of rotating blocks 66 will move synchronously driven by the support shaft 61. The support assembly 6 also includes a sleeve 62 for accommodating the support shaft 61. The outer wall of the sleeve 62 is fixedly connected to the top end of the support plate 1, and the support shaft 61 is rotatably connected to the inner wall of the sleeve 62.

The top of the torsion spring 64 is fixedly connected to the inner wall of the receiving groove 63. When the support shaft 61 rotates under the drive of the rotating block 66, the support shaft 61 will squeeze the torsion spring 64 to deform it. When the rotating block 66 is not squeezed, the torsion spring 64 will deform in the reverse direction to drive the support shaft 61 to rotate and reset in the reverse direction. The top of the receiving groove 68 slides The dynamic connection has a pressing block 65 for squeezing the rotating block 66. The front end of the pressing block 65 is set as a plane. When the pressing block 65 moves downward, the plane will be used to squeeze the top of the rotating block 66 to force the rotating block 66 to rotate until the top of the rotating block 66 is in contact with the front end of the pressing block 65. The rotating block 66 is set to be semicircular, so that the outer wall of the rotating block 66 can be in contact with the inner wall of the storage groove 68, which can prevent foreign matter from entering the interior of the storage groove 68. The top of the rotating block 66 is fixedly connected to a stopper 67 for fixing the front end of the mobile phone.

[0038] When the mobile phone needs to be charged, the mobile phone can be placed directly on the top of the support plate 1. The mobile phone will be tightly attached to the top of the support plate 1 under the action of the magnetic block 2. At the same time, the mobile phone will squeeze the pressing block 65 downward to make it move downward. The downward movement of the pressing block 65 will squeeze the rotating block 66 to make it rotate until the top of the rotating block 66 fits with the front end of the pressing block 65. At this time, the stopper 67 will block the front end of the mobile phone to fix it.
