Various embodiments of the present disclosure provide a wireless charger 20, a three-dimensional schematic diagram of which is illustrated in
The wireless charger 20 can be used to charge a device being charged, herein, the device being charged can be a terminal device such as a mobile phone etc., and the wireless charger can be a vertical type or a tablet type. The wireless charger 20 can include: a charging base 21, a support portion 22, a charging coil 23 and the cross-flow fan 24.
Herein, the charging base 21 is disposed at a lower part of the wireless charger 20, and the charging base 21 can be provided with circuit components such as a power supply etc. of the charger, and can support the support portion 22.
The support portion 22 is disposed above the charging base 21, and is used to support the device being charged. The support portion 22 for supporting the device being charged is disposed above the charging base 21. In some embodiments, as shown in
The charging coil 23 is disposed on the support portion 22, and used to charge the device being charged. The battery of the device being charged can be charged in a non-contact manner through the charging coil 23. When the device being charged is placed or leaned on the support portion 22, a charging position of the device being charged corresponds to the area of the charging coil 23, thereby forming a charging area.
The cross-flow fan 24 is disposed above the charging base 21, it has a fan air outlet 241 extending along a width direction of the support portion 22, and dissipates heat away from the device being charged and/or the wireless charger 20 through exhaust air. Herein, the width direction of the support portion 22 can be the width direction identified in
In the above embodiment, as shown in
In some embodiments, the cross-flow fan 24 can include: a fan housing 242 having a cylindrical shape, and disposed to extend along the width direction of the support portion 22; a fan air inlet 243 opened on an axial end face on one side or both sides of the fan housing 242, or opened on a radial peripheral surface of the fan housing 242, which enable the air inlet smoother; and a fan air outlet 241 disposed in a radial direction of the fan housing 242 and extending along an axial direction. The cross-flow fan 24 can further include shafts and blades, which are not shown in the figures, disposed inside the fan housing 242.
The cross-flow fan 24 rotates through the blades in the fan housing 242, takes in air from the fan air inlet 243 and exhausts the air through the fan air outlet 241 to generate the wind for heat dissipation. The cross-flow fan 24 can discharge the wind propagating linearly in the radial direction from the fan air outlet 241 and blow the wind in parallel to the charging area in the width direction of the support portion 22 to dissipate heat.
In some embodiments, the support portion 22 can include: a casing 221 in which the charging coil 23 and the cross-flow fan 24 can be disposed, and the cross-flow fan 24 is disposed under the charging coil 23; a first surface 2211 of the casing 221 is used to support the device being charged; and a casing air outlet 2212 is disposed on the first surface 2211 and extends along the width direction of the support portion 22, and the fan air outlet 241 of the cross-flow fan 24 is adjacent to an inner side of the casing air outlet 2212.
In the embodiments of the present disclosure, the casing 221 can be an integrative structure, or can be formed by combining multiple components, and in an example, as shown in
In the vertical wireless charger, the cross-flow fan 24 can be located at a lower position in the casing 221, and the fan air outlet 241 thereof can be disposed near the casing air outlet 2212 of the first surface 2211, or can be directly coupled to the casing air outlet 2212, thereby ensuring that the wind blown out from the cross-flow fan 24 can be blown out through the casing air outlet 2212. The charging coil 23 is located in the casing 221 and is located at a position above the cross-flow fan 24, which corresponds to a general charging position of the device being charged, the wind blown out from the fan air outlet 241 of the cross-flow fan 24 is blown out through the casing air outlet 2212 and then goes through the charging area corresponding to the charging coil 23 to dissipate heat and cool down the device being charged and the like.
In some embodiments, a side part and/or a rear part of the casing 221 are provided with a casing air inlet (not shown in the figures). The casing 221 can be provided with a casing air inlet at a corresponding position near the fan air inlet 243 of the cross-flow fan 24, the air can smoothly enter the housing 221 and smoothly enter the cross-flow fan 24 through the fan air inlet 243, such that the cross-flow fan 24 has a better blowing effect, thereby improving the heat dissipation effect.
In some embodiments, the first surface 2211 of the casing 221 includes: a support surface 22111, a charging surface 22112 and a stepped surface 22113. Herein, the support surface 22111 is located at a lower part of the first surface 2211 and is used to support a lower part of the device being charged. The support surface 22111 mainly serves to support the device being charged. The charging surface 22112 is located at an upper part of the first surface 2211, and the charging coil 23 is located at a rear side of the charging surface 22112, and when the device being charged is being charged, the charging area corresponds to an area located in the charging surface 22112. The stepped surface 22113 extends along the width direction of the support portion 22, the support surface 22111 and the charging surface 22112 are connected through the stepped surface 22113, and when the step surface 22113 makes the device being charged supported on the support surface 22111, there is a gap between the device being charged and the charging surface 22112.
A gap formed in the charging area can improve the heat dissipation effect, allow air to circulate, and enable the wind blown out by the fan to flow through the area thereby dissipating heat. Therefore, the first surface 2211 adopts the above result, the support surface 22111 at the lower part supports the device being charged, and the charging surface 22112 can be parallel to the support surface 22111 and slightly away from the device being charged as compared with the support surface 22111, thereby forming a gap. The height difference between the support surface 22111 and the charging surface 22112 forms the stepped surface 22113. The casing air outlet 2212 is disposed on the stepped surface 22113, such that the wind blown out by the cross-flow fan 24 can flow through the charging surface 22112 after being blown out through the casing air outlet 2212, thereby dissipating heat.
In some embodiments, the stepped surface 22113 includes: a middle section 22113a, a first side section 22113b and a second side section 22113c; the middle section 22113a is located at a middle part of the stepped surface 22113, and extends along the width direction of the support portion 22; and the first side section 22113b and the second side section 22113c are coupled to both ends of the middle section 22113a respectively, extend toward an upper part of the support portion 22, and connect to side surfaces of the casing 221.
As shown in
In some embodiments, openings can be provided on the middle section 22113a, the first side section 22113b and the second side section 22113c of the stepped surface 22113 to form the casing air outlet 2212.
In some other embodiments, an opening can be provided only on the middle section 22113a to form the casing air outlet 2212, such that the wind blown out is more concentrated, the first side section 22113b and the second side section 22113c play a role of wind gathering, and also enable the support surface 22111 to extend, on the side, toward the upper part of the support portion 22, and better support the device being charged.
In some embodiments, the charging coil 23 is disposed inside the casing 221 movably. In the present embodiment, the position of the charging coil 23 can be moved, such that it can adapt to different devices to be charged. At present, due to differences in the type and model of the devices to be charged, the charging position of each device being charged is not necessarily the same, and in order to improve charging efficiency, the position of the charging coil 23 can be moved to adjust, such that the charging coil 23 is aligned with the charging position of the device being charged.

In some embodiments, the wireless charger 20 further includes: a drive component disposed inside the casing 221, coupled to the charging coil 23, and used to drive the charging coil 23 to move along a length direction of the support portion 22 inside the casing 221. In these embodiments, the position of the charging coil 23 is adjusted by the drive component. The drive component can take a variety of forms, such as cylinders and the like.
Various embodiments of the present disclosure provide a configuration mode of the drive component, as shown in

By using the cross-flow fan, a size of the vertical wireless charger in a length direction can be reduced, and the wind propagates in a straight line and covers a larger size of the wireless charger in the width direction. As such, the heat dissipation effect can be improved, and the wind can propagate over a longer distance.
