[0024] Refer to Figures 1-5 , a magnetic - type in - vehicle wireless charger with a heat - dissipation function provided by the present utility model: It includes a hollow outer shell 1. Inside the outer shell 1, there is a charger main body 2. On the side of the outer shell 1, two placement slots are opened. Inside both of the two placement slots, there are fixedly arranged hollow limit blocks 3. The limit blocks 3 facilitate the limitation of the connecting rods 4. Inside both of the two limit blocks 3, there are slidingly connected connecting rods 4. On the sides of both of the two connecting rods 4, there are fixedly arranged moving plates 5. The moving plates 5 facilitate driving the connecting rods 4 to move. The sides of both of the two moving plates 5 are respectively slidingly connected to the inside of the two limit blocks 3. On one side of both of the two moving plates 5, there are fixedly arranged return springs 6. The return springs 6 facilitate the extrusion of the moving plates 5. One sides of both of the two return springs 6 are respectively fixedly connected to the inside of the two limit blocks 3. At one end of both of the two connecting rods 4, there are fixedly arranged pull rings 7. The pull rings 7 facilitate driving the connecting rods 4 to move. Inside the outer shell 1, there is a limit ring 8. At the bottom end of the limit ring 8, there is fixedly arranged a protection frame 9. Inside the protection frame 9, there are several installation slots. Inside each of the several installation slots, there is an installation block 10. Between several installation blocks 10, there is fixedly arranged a cooling fan 11. On the top end of the outer shell 1, there are several heat dissipation holes.

[0025] As a further implementation of the above - mentioned technical solution: On the side of the limit ring 8, there are two limit slots. The inside of the two limit slots respectively fits with the sides of the two limit blocks 3. The limit ring 8 facilitates the limitation of the outer shell 1.

[0026] As a further implementation of the above - mentioned technical solution: Inside the limit ring 8, there are two connection holes. The inside of the two connection holes respectively fits with the sides of the two connecting rods 4. The connecting rods 4 facilitate fixing the limit ring 8 and the outer shell 1 together.

[0027] As a further implementation of the above - mentioned technical solution: Inside the outer shell 1, there is a fixed slot. The inside of the fixed slot is fixedly connected to the side of the charger main body 2. The outer shell 1 facilitates fixing the charger main body 2.

[0028] During specific implementation: When the mobile phone needs to be charged, place the mobile phone on the top of the charger main body 2, and the mobile phone is adsorbed on the surface of the charger main body 2 through the magnet on the surface of the charger main body 2. The mobile phone is charged through the charging coil inside the charger main body 2. When the mobile phone generates heat during charging, start the cooling fan 11. The cooling fan 11 generates wind, so that the wind blows to the surface of the mobile phone through the heat dissipation holes to dissipate heat from the mobile phone. When the cooling fan 11 is damaged and needs to be replaced, separate the two connecting rods 4 through the pull ring 7, so that the connecting rods 4 are disengaged from the connection holes. At this time, move the outer shell 1 upward, so that the outer shell 1 is disengaged from the limiting ring 8. At this time, the top of the protective frame 9 is open, and the cooling fan 11 can be directly taken out. Replace the spare cooling fan 11, put the cooling fan 11 into the protective frame 9, and prevent the cooling fan 11 from shaking during use through the mounting block 10 and the mounting groove. Move the outer shell 1 downward so that the inner side of the outer shell 1 fits with the outer side of the limiting ring 8, and the inside of the limiting groove fits with the side of the limiting block 3. Release the pull ring 7, and push the two moving plates 5 to approach each other through the reset spring 6, thereby driving the two connecting rods 4 to approach each other, so that the connecting rods 4 enter the limiting ring 8, so that the outer shell 1 and the limiting ring 8 are fixed together, thus completing the installation of the cooling fan 11. At this time, the cooling fan 11 can normally dissipate heat from the mobile phone, so that the device is convenient for disassembling and assembling the cooling fan 11, and it is convenient to quickly replace the cooling fan 11 after it is damaged, avoiding damage to the mobile phone due to overheating caused by the long-term inoperability of the cooling fan 11, thereby improving the heat dissipation efficiency of the device for the mobile phone.

[0029] As a further implementation of the above technical solution: Two rotating disks 12 are fixedly provided at the bottom end of the protective frame 9, and a support rod 13 is rotatably connected between the two rotating disks 12. The support rod 13 is convenient for limiting the rotating disk 12.

[0030] As a further implementation of the above technical solution: A number of positioning holes are provided inside one of the rotating disks 12. A fixing plate 14 is fixedly provided on the side of the support rod 13. A positioning rod 15 is threadedly connected inside the fixing plate 14. The positioning rod 15 is convenient for fixing the support rod 13 and the rotating disk 12 together.

[0031] As a further implementation of the above technical solution: The side of the positioning rod 15 fits with the inside of one of the positioning holes. One end of the positioning rod 15 is fixedly provided with a knob 16. The knob 16 is convenient for driving the positioning rod 15 to rotate.

[0032] As a further implementation of the above technical solution: A support plate 17 is fixedly provided on the side of the support rod 13. A base 18 is fixedly provided at the bottom end of the support plate 17. The base 18 and the support plate 17 are convenient for supporting the device.

[0033] During specific implementation: The inclination angle of the existing charger main body 2 is fixed, so that the inclination angle of the mobile phone is fixed when placed. Since the heights of different users are different, it is easy to make the angle between the user's line of sight and the mobile phone too large, which makes the mobile phone prone to reflection, speeds up the fatigue speed of the user's eyes, and reduces the use comfort of the device. Rotate the knob 16, which drives the positioning rod 15 to rotate, so that the positioning rod 15 moves to the right, so that the positioning rod 15 disengages from the positioning hole, drives the rotating disc 12 to rotate back and forth, and thus can drive the protective frame 9 to rotate back and forth, and thus can drive the limiting ring 8, the housing 1 and the charger main body 2 to rotate back and forth, so that the inclination angle of the charger main body 2 can be adjusted, and thus the inclination angle of the mobile phone can be adjusted. After the adjustment is completed, reverse the knob 16, which drives the positioning rod 15 to reverse, and thus drives the positioning rod 15 to move to the left, so that the positioning rod 15 enters the corresponding positioning hole, so that the rotating disc 12 is limited, so that the protective frame 9, the housing 1 and the charger main body 2 are limited, so that the device is convenient to adjust the inclination angle of the mobile phone when placed, so that the device is suitable for users of different heights, and thus the use comfort of the device is improved.
