As shown in fig. 7 and 8, in one embodiment, the driving mechanism 500 includes a rack 540, a gear 530, a rotating shaft 510, and a bushing 520. The sleeve 520 is fixed to a side of the bracket 400 facing the second panel 220, for example, the sleeve 520 is integrally formed with the bracket 400. The shaft 510 penetrates the shaft sleeve 520 and can rotate relative to the shaft sleeve 520. The two ends of the rotating shaft 510 are respectively located outside the shaft sleeve 520, and are respectively fixed with a gear 530. That is, the number of the gears 530 is 2, and 2 gears 530 are respectively fixed to both ends of the rotation shaft 510. As shown in fig. 4 and 6a, the number of the racks 540 is 2, and 2 racks 540 are fixed to the second panel 220. The 2 gears 530 are engaged with the 2 racks 540, respectively. When the rotating shaft 510 rotates relative to the sleeve 520, the gear 530 rotates relative to the rack 540, so as to drive the bracket 400 to approach or depart from the first body 20, and the position of the coil module 300 is changed to adapt to devices to be charged with different sizes.

In another embodiment, the number of the gear 530 is 1, the number of the rack 540 is 1, the gear 530 is engaged with the rack 540, and the rack 400 can be driven to approach or separate from the first body 20 when the gear 530 rotates relative to the rack 540.

As shown in fig. 1 and 3, in an embodiment, the driving mechanism 500 includes a knob 550, and the first sidewall 230 is opened with a strip-shaped through slot 231. The knob 550 is fixed at the end of the rotating shaft 510, and the knob 550 penetrates the through groove 231 and is located outside the second housing 200. When the position of the coil module 300 needs to be adjusted, the exposed knob 550 can be rotated, the knob 550 drives the rotating shaft 510 to rotate in the shaft sleeve 520, so as to drive the gear 530 to rotate relative to the rack 540, and because the rack 540 is fixed to the second panel 220, the gear 530 drives the bracket 400 to rotate in the second housing 200 to be close to or far away from the first body 20, so that the coil module 300 corresponds to a coil in a device to be charged. Meanwhile, the strip-shaped through groove 231 provides an avoiding space for the rotation of the knob 550 or the rotating shaft 510, so that interference between the second housing 200 and the knob 550 or the rotating shaft 510 is avoided in the moving process of the bracket 400. In one embodiment, when the knob 550 is rotated clockwise, the knob 550 and the bracket 400 are moved away from the first body 20 together; when the knob 550 is rotated counterclockwise, the knob 550 and the bracket 400 come close to the first body 20 together.

As shown in fig. 9 and 13, the first sidewall 230 is formed with a through hole 232, and the knob 550 is exposed out of the second housing 200 through the through hole 232 and connected to the rotating shaft 510. Rotation of knob 550 may cause movement of bracket 400. When the position of the coil module 300 needs to be adjusted, the knob 550 may be rotated so that the bracket 400 can be moved closer to or away from the first body 20. For example, when the knob 550 is rotated clockwise, the bracket 400 is away from the first body 20, and when the knob 550 is rotated counterclockwise, the bracket 400 is close to the first body 20.

As shown in fig. 13 and 14, in one embodiment, the number of the racks 540 is 2, and the racks are respectively fixed to both sides of the bracket 400. The number of the gears 530 is two, and the gears are respectively fixed to both ends of the rotation shaft 510. As shown in fig. 15 and 16, 2 gears 530 are respectively engaged with two racks 540, and when the gears 530 rotate relative to the racks 540, the racks 540 can move the bracket 400 to approach or separate from the first body 20.

As shown in fig. 10 and 14, in an embodiment, the first sidewall 230 and the second sidewall 240 are both provided with a through hole 232. The knob 550 is fixed at one end of the rotating shaft 510, and the knob 550 passes through the through hole 232 of the first sidewall 230 and is exposed out of the second housing 200. One end of the rotating shaft 510, which is far away from the knob 550, penetrates through the through hole 232 of the second sidewall 240 and can rotate relative to the through hole 232, so that both ends of the rotating shaft 510 are supported by the through hole 232, and the rotating shaft 510 can rotate relative to the second housing 200. When the position of the coil module 300 needs to be adjusted, the knob 550 can be rotated, and the knob 550 drives the rotating shaft 510 to rotate, so that the gear 530 can rotate along the rack 540. Because both ends of the rotating shaft 510 are limited by the through holes 232, the rack 540 can move in the second housing 200, thereby driving the bracket 400 to be close to the first main body 20 or far away from the first main body 20, and completing the adjustment of the position of the coil module 300.

In another embodiment, the number of the gear 530 is 1, the number of the rack 540 is 1, the gear 530 is engaged with the rack 540, and the rack 400 can be driven to approach or separate from the first body 20 when the gear 530 rotates relative to the rack 540.

The second top plate 120 is made of a heat insulating material to prevent heat transfer between the circuit board 700 and the coil module 300. The second accommodating cavity 102 is provided with a heat conducting layer with a higher coefficient, and the heat conducting layer is located between the circuit board 700 and the bottom plate 130 and is of a mud-like structure. The heat conductive layer is made of a heat conductive material such as silicone grease or the like so that heat of the circuit board 700 is transferred to the base plate 130 through the heat conductive layer. It is understood that the side of the circuit board 700 facing the bottom plate 130 may be a plane or a curved surface, and if the circuit board 700 is attached to the bottom plate 130, the two may not be completely attached, so that the heat transfer efficiency between the two is low. The heat conduction layer is formed by filling the mud-shaped heat conduction material, so that the contact area is increased, and the heat conduction coefficient is higher, so that the heat transfer efficiency between the circuit board 700 and the bottom plate 130 is higher.

In the wireless charging device 10 of the present application, the second body 30 is obliquely disposed on the first body 20, the first casing 100 has a first air opening 141 and a second air opening 151, and the second body 30 is located at the second air opening 151. The fan 600 is disposed in the first casing 100, and the fan 600 is provided with a third air opening 610 and a fourth air opening 620. The first air opening 141, the second air opening 151, the third air opening 610 and the fourth air opening 620 form a heat dissipation air duct with small wind resistance, and the heat dissipation effect is good. The position of the coil module 300 in the second housing 200 is adjustable, and the position of the coil module 300 can be adjusted for different devices to be charged, so that the coil module 300 can correspond to the coil in the device to be charged, and the charging efficiency is improved. When the fan 600 works, the air at the second air opening 151 can take away the heat transferred to the second housing 200 by the device to be charged and the coil module 300, so that the temperature of the device to be charged and the coil module 300 is reduced. The heat of the circuit board 700 can be transferred to the first housing 100 through the heat conducting layer, so that the influence of the heat of the circuit board 700 on the heat dissipation effect of the device to be charged is reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
