To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment, the wireless charging cradle 10 includes a first cradle 100 and a second cradle 200. The first base 100 includes a first housing 110 and a coil module 120, and the coil module 120 is disposed in the first housing 110. The second base 200 includes a second housing 210, and the second housing 210 is connected to the first housing 110 and can rotate relative to the first housing 110, so that the wireless charging base 10 can be switched between a folded state and an unfolded state. Referring to fig. 1 and 2, the first fastening structure 100 is stacked on the second fastening structure 200 in the folded state; referring to fig. 4, the first cradle 100 is assembled with the second cradle 200 in the unfolded state, and the length of the wireless charging cradle 10 in the folded state is less than that of the wireless charging cradle 10 in the unfolded state. Specifically, in some embodiments, the first housing 110 has a substantially rectangular block shape with a mounting cavity formed therein. The second housing 210 has a substantially rectangular block shape, and a mounting cavity is formed therein. The cross-sectional area of the first casing 110 is equivalent to the cross-sectional area of the second casing 210, and when the first casing 110 is folded, the circumferential outer surface of the first casing 110 is flush with the circumferential outer surface of the second casing 210, that is, when the wireless charging stand 10 is viewed from the top end of the wireless charging stand 10 along the thickness direction of the wireless charging stand 10 when the wireless charging stand is folded, the circumferential profile of the first housing 100 substantially coincides with the circumferential profile of the second housing 200, as shown in fig. 1 and 2. This arrangement allows the wireless charging cradle 10 to have a relatively high integrity in a folded state, thereby enhancing the appearance of the wireless charging cradle 10. Of course, in other embodiments, the shapes of the first housing 110 and the second housing 210 may be different, for example, the outer contour of the cross section of the first housing 110 may be arcuate, and the second housing 210 may be rectangular block-shaped.

Referring to fig. 3, in the embodiment of the present application, one end of the first casing 110 is provided with a first mounting groove 111, one end of the second casing 210 is provided with a second mounting groove 211, and the wireless charging stand 10 includes a rotating shaft 300, wherein the rotating shaft 300 is accommodated in the first mounting groove 111 and the second mounting groove 211 and is rotatably connected to the first casing 110 and the second casing 210, respectively. Specifically, in the present embodiment, the rotating shaft 300 has a biaxial structure, i.e., the rotating shaft 300 has two rotational axes. The end face of the first housing 110, which is provided with the first mounting groove 111, and the end face of the second housing 210, which is provided with the second mounting groove 211, are flat surfaces, and when the wireless charging stand 10 is switched from the folded state to the unfolded state, the first housing 110 rotates by about 180 degrees relative to the second housing 210, so that the end face of the first mounting groove 111 is in butt joint with the end face of the second mounting groove 211, and the first seat 100 is spliced with the second seat 200. Further, in the embodiment of the present application, by providing the first mounting groove 111, the second mounting groove 211, and the rotating shaft 300 having a biaxial structure, the end surface of the first housing 110 on the side of the rotating shaft 300 can be flush with the end surface of the second housing 210 in the folded state. Further, the exposed end surface of the rotating shaft 300 may be flush with the end surface of the first housing 110 when the wireless charging stand is folded, so that the wireless charging stand 10 has relatively high integrity when the wireless charging stand is folded, and the appearance characteristics of the wireless charging stand 10 are improved.

Of course, in other embodiments, the rotation angle of the first housing 110 relative to the second housing 210 can be less than or greater than 180 degrees during the process of switching the wireless charging stand 10 from the folded state to the unfolded state. For example, the rotation angle of the first housing 110 with respect to the second housing 210 may range from 0 degree to 170 degrees, or the rotation angle of the first housing 110 with respect to the second housing 210 may range from 0 degree to 190 degrees. Of course, in other embodiments, the rotating shaft 300 having a double-shaft structure is not necessary, for example, the first casing 110 and the second casing 210 may be rotatably connected by the rotating shaft 300 having a single-shaft structure, that is, the rotating shaft 300 has 1 rotating axis. Further, in other embodiments, the rotating shaft 300 is not necessary, for example, one of the first housing 110 and the second housing 210 may be provided with a protrusion, and the other of the first housing 110 and the second housing 210 may be provided with a shaft hole, and the protrusion can be received in the shaft hole and rotatably engaged with the shaft hole, so that the first housing 110 can rotate relative to the second housing 210 and the wireless charging stand 10 can be switched between the folded state and the unfolded state.

Further, referring to fig. 3, the second housing 200 includes a circuit board 220, and referring to fig. 5 and 6, the circuit board 220 is disposed in the second casing 210 and electrically connected to the coil module 120. In some embodiments, the second housing 200 includes an electrical connection interface electrically connected to the circuit board 220, the electrical connection interface is used for connecting an external power source to power the wireless charging dock 10, so that the wireless charging dock 10 can be used to charge the electronic device. The electric connection interface can be a USB interface, and can also be a cable with a plug, and the like. Of course, in other embodiments, the electrical connection interface may also be located on the first housing 110. Further, the first housing 110 or the second housing 210 can be provided with an indicator light for prompting the operating status of the wireless charging cradle 10. Of course, in other embodiments, the circuit board 220 may be disposed in the first housing 110, or the circuit board 220 may be disposed in the first housing 110 and the second housing 210 respectively.

Further, the first housing 110 includes a charging area 113 covering the coil module 120, the charging area 113 is a portion of the first housing 110, and the charging area 113 is used for placing an electronic device for wireless charging. Referring to fig. 6, in the present embodiment, the charging region 113 is located on a side of the first seat 100 facing away from the second seat 200 in the folded state, and the charging region 113 is capable of placing an electronic device for wireless charging in the folded state. This arrangement can enhance the convenience of use of the wireless cradle 10. In other embodiments, the charging region 113 may be located on a side of the first seat 100 facing the second seat 200 in the folded state, that is, the charging region 113 is shielded by the second seat 200 in the folded state.

In some embodiments, the outer surface of charging region 113 is a flat surface. In other embodiments, the charging region 113 may be in a groove shape, that is, the charging region 113 may have a structure with two sides being higher and a middle being lower, so that when the electronic device is placed in the charging region 113, a gap can be formed between the surface of the electronic device and the middle of the charging region 113, thereby facilitating heat dissipation of the electronic device. Further, in some embodiments, two opposite edges of the charging area 113 may be respectively provided with a silicone strip, so as to support an electronic device with a relatively large size, such as a smart phone, a tablet computer, and the like, by using the silicone strip, and form an interval between the rear surface of the electronic device and the outer surface of the charging area 113, so as to facilitate heat dissipation of the electronic device and the wireless charging stand. Small-sized electronic devices such as smartwatches, wireless headsets, etc. may be charged against the outer surface of the charging region 113. Of course, in other embodiments, the silicone strip may be replaced with a rubber strip or a plastic strip.

Further, in an embodiment, the second housing 200 includes a fan 230 disposed in the second casing 210, and the fan 230 is electrically connected to the circuit board 220. The fan 230 may be fixedly coupled to the second housing 210 by means of a screw connection, or welding or bonding, etc. The second housing 210 is provided with a first tuyere 213 and a second tuyere 215, and in conjunction with fig. 7 and 8, the second tuyere 215 is closer to the charging region 113 than the first tuyere 213 in the expanded state. The fan 230 can guide the inflow of the external air from one of the first and

second vents

213 and 215 into the second housing 210 and the outflow of the air from the other of the first and

second vents

213 and 215 so that the air at the second vent 215 can exchange heat with the electronic devices.

In some embodiments, the second tuyere 215 is disposed at one end of the second housing 210 and is located at the same end of the second housing 210 as the rotating shaft 300. The first air opening 213 is disposed at the opposite end of the second casing 210, the fan 230 can guide the outside air to flow into the second casing 210 from one of the first air opening 213 and the second air opening 215, and guide the air to flow out of the second casing 210 from the other of the first air opening 213 and the second air opening 215, and the air at the second air opening 215 can generate relative flow with the air in the space near the charging area 113 in the unfolded state, so as to exchange heat with the electronic device, thereby facilitating the heat dissipation of the electronic device, and improving the heat dissipation performance of the wireless charging stand 10. Of course, in other embodiments, the first tuyere 213 may be disposed at other positions of the first housing 110, for example, the first tuyere 213 may be disposed at other side circumferential surfaces of the second housing 210.

In some embodiments, the fan 230 is a centrifugal fan, and the rotating shaft 300 of the fan 230 is disposed parallel to the thickness direction of the wireless charging stand 10, which is favorable for reducing the overall thickness of the second base 200, so as to be favorable for the light and thin design of the wireless charging stand 10. Of course, in other embodiments, the fan 230 may be an axial fan. Further, in some embodiments, the thickness of the second housing 200 is greater than the thickness of the first housing 100, and the second housing 200 protrudes from the charging region 113 in the unfolded state, so that the second air opening 215 is exposed and faces the charging region 113. This structure may form a relatively large installation cavity inside the second housing 210 to facilitate the arrangement of the fan 230 and the circuit board 220, and in the unfolded state, the structure is arranged to facilitate the relative flow of the air at the second air opening 215 and the air in the space near the charging region 113. Of course, in other embodiments, the thickness of the first housing 100 may be equivalent to that of the second housing 200, and the fan 230 may be arranged to guide the air at the second air outlet 215 to flow relative to the air in the space near the charging region 113.

Further, in some embodiments, first housing 110 and second housing 210 are flush on a side facing away from charging region 113 in the deployed state. This arrangement enables the wireless charging cradle 10 to be smoothly placed on a support (e.g., a table top) when in the unfolded state. Further, in some embodiments, a side of the first housing 110 facing away from the charging region 113 and a side of the second housing 210 may further be provided with a pad, and the pad may contact a surface of the support in the unfolded state to prevent the wireless charging stand 10 from easily sliding on the support. The gasket can be made of silica gel or rubber.

It is understood that the relative flow of air at the second air port 215 and the space near the charging region 113 may include two forms. In some embodiments, the fan 230 may direct air to flow into the second housing 210 from the first air opening 213 and direct air to flow out of the second housing 210 from the second air opening 215, thereby enabling the air at the second air opening 215 to exchange heat with air in the space near the charging region 113 when in the deployed state. In other embodiments, the fan 230 may direct air to flow into the second housing 210 from the second port 215 and direct air to flow out of the second housing 210 from the first port 213, which also enables the air at the second port 215 to exchange heat with the air in the space near the charging region 113 in the deployed state.

Further, in some embodiments, the second air opening 215 communicates with the installation cavity of the second casing 210 and the installation cavity of the first casing 110 in the unfolded state, and the fan 230 can also guide the air in the first casing 110 to flow relatively with the air in the second casing 210 for heat exchange. Specifically, in some embodiments, the first casing 110 is provided with an air opening, and the second air opening 215 is communicated with the air opening of the first casing 110 in the unfolded state, so that the fan 230 can guide the air in the first casing 110 and the air in the second casing 210 to generate relative flow for heat exchange, thereby facilitating the heat dissipation of the coil module 120 and improving the heat dissipation performance of the wireless charging stand 10.

Further, referring to fig. 8, the second housing 200 includes a partition 240, and the partition 240 is connected to the second casing 210 and forms a first chamber 201 and a second chamber 203 separated from the second casing 210. Referring to fig. 6, in the folded state, the first chamber 201 is located on a side of the partition 240 facing the first housing 100, and the circuit board 220 is disposed in the first chamber 201. This arrangement separates the circuit board 220 from the fan 230 to prevent the fan 230 from adversely affecting the electronic components on the circuit board 220 during operation. For example, this arrangement may reduce the effect of heat generated by the fan 230 during operation on the electronic components of the circuit board 220. In some embodiments, the first chamber 201 and the second chamber 203 may be completely isolated, i.e., the first chamber 201 and the second chamber 203 are not in communication. In other embodiments, the first chamber 201 and the second chamber 203 may be in communication, and the partition 240 may reduce the influence of the fan 230 on the electronic components of the circuit board 220 during operation. Of course, in other embodiments, the circuit board 220 may be disposed in the second chamber 203 and the fan 230 may be disposed in the first chamber 201.

The partition 240 may be made of a metal material, such as an aluminum alloy or a magnesium alloy, and the second housing 210 may also be made of a metal material, such as an aluminum alloy or a magnesium alloy, so that the second housing 210 has relatively high structural strength. Further, the circuit board 220 may be fixedly connected to the partition 240 by welding, bonding, or screwing, and a heat conductor may be disposed between the partition 240 and the circuit board 220, and the heat conductor may conduct heat generated by the circuit board 220 to the second housing to facilitate heat dissipation of the circuit board 220. Specifically, the heat conductor may be silicone grease or the like to conduct the heat generated by the circuit board 220 to the second casing 210 made of metal, and further dissipate the heat generated by the circuit board 220 to the air through the second casing 210, so as to further improve the heat dissipation performance of the wireless charging stand 10. Of course, in other embodiments, the partition 240 may be made of a non-metal material, such as plastic, rubber, or ceramic, and the second housing 210 may also be made of a non-metal material, such as plastic, ceramic, and so on, which will not be described herein.

When the wireless charging stand 10 is folded, electronic devices such as a smart watch and a wireless headset having a wireless charging function and relatively low charging power can be placed in the charging area 113 for charging. Of course, such electronic devices can be placed in the charging area 113 for wireless charging when the wireless charging cradle 10 is in the unfolded state. In the deployed state, the fan 230 may or may not be active. For example, a temperature sensor may be disposed on the first casing 110, and in the unfolded state, when the temperature sensor detects that the temperature of the charging area 113 exceeds a certain threshold, the fan 230 is activated to increase the heat dissipation performance of the wireless charging stand 10 and reduce the power consumption of the wireless charging stand 10.

For electronic devices with wireless charging function and relatively large charging power, such as smart phones, tablet computers, etc., the wireless charging cradle 10 can be placed in the unfolded state and such electronic devices can be placed in the charging area 113 for wireless charging. Referring to fig. 8, in some embodiments, the fan 230 can supply air from the second air opening 215, and the air flow flows through the periphery of the electronic device to exchange heat and emit the air, thereby facilitating heat dissipation of the electronic device and the wireless charging stand 10. In other embodiments, the fan 230 can draw air from the second air opening 215, and the air around the electronic device is guided into the second housing 210 and then flows out of the second housing 210 through the first air opening 213, which also facilitates heat dissipation of the electronic device and the wireless charging dock 10.

Referring to fig. 8, the first base 100 includes a magnetic shielding sheet 130 disposed in the first housing 110, and the coil module 120 is stacked on the magnetic shielding sheet 130. The magnetic shield sheet 130 can be made of ferrite wave-absorbing material, and has excellent magnetic conductivity, so that the magnetic flux of the coil module 120 can be increased, the loss of the coil module 120 can be reduced, the magnetic induction line can tightly surround the surrounding area with the magnetic shield sheet 130 as the center to increase the electromagnetic induction intensity, and the electromagnetic conversion efficiency can be improved. The magnetic shield 130 may be attached to the first housing 110 or attached to the first housing 110 by other structures.

Further, in some embodiments, the first housing 110 protrudes toward the coil module 120 to form a protrusion 115, the magnetic shielding sheet 130 is disposed on the protrusion 115, and with reference to fig. 9, the protrusion 115 forms a groove 117 on a side away from the coil module 120, and the second seat 200 covers the groove 117 when folded, as shown in fig. 6. With such a structure, the boss 115 can effectively support the coil module 120, and the groove 117 formed on the back side of the boss 115 can save the material of the first housing 110, so as to save the material cost of the wireless charging stand 10. Of course, the boss 115 is not necessary, and for example, a side of the first housing 110 facing away from the charging region 113 may have no groove 117 structure.

Above-mentioned wireless charging seat 10, electronic equipment such as smart mobile phone, intelligent wrist-watch, wireless earphone that have wireless function of charging all can place in charging district 113 and carry out wireless charging, and wireless charging seat 10 can the multiple model of adaptation, has promoted the convenience of using. The heat dissipation air duct of the wireless charging stand 10 is easy to design, has a better heat dissipation effect, and can meet the requirement of high-power wireless charging so as to shorten the wireless charging time. Above-mentioned wireless charging seat 10, because first casing 110 can rotate so that wireless charging seat 10 switches between fold condition and expansion state relative to second casing 210, and the length of the wireless charging seat 10 of fold condition is less than the length of the wireless charging seat 10 of expansion state, wireless charging seat 10 during fold condition has relatively less length size, the wireless charging seat 10 of being convenient for accomodate, can promote the portability of wireless charging seat 10.

Referring to fig. 10, 11 and 12, in another embodiment, the fan 230 of the second housing 200 is replaced by another coil module 250, and the second housing 210 includes another charging region 217 covering the other coil module 250, and the other charging region 217 can be used to place an electronic device for wireless charging when the second housing is folded. Referring to fig. 13 and 14 together, in other words, in this embodiment, when the wireless charging cradle 10 is in the folded state, the charging area 113 of the first housing 110 can wirelessly charge the electronic device, and in conjunction with fig. 11 and 12, the other charging area 217 of the second housing 210 can also wirelessly charge the electronic device, so as to improve the convenience of the wireless charging cradle 10. During the use process, the user can select the charging area 113 of the first housing 110 to wirelessly charge the wireless charging stand 10 in the folded state, and can also select another charging area 217 of the second housing 210 to wirelessly charge the wireless charging stand. Of course, in this embodiment, the second base 200 may include another magnetic shield 260 disposed in the second housing 210, the other coil module 250 may be stacked on the other magnetic shield 260, and the function of the other magnetic shield 260 is the same as that of the magnetic shield 130 of the first base 100, which will not be described herein again. In the embodiment that the second housing 200 is provided with another coil module, the second housing 210 does not need to be provided with a tuyere-related structure, in combination with fig. 13 and 14. Of course, the tuyere-related structure can be reserved for heat dissipation of the second housing 200.

In an embodiment where the second housing 200 includes another coil module 250, the partition 240 and the second housing 210 form a first chamber 201 and a second chamber 203 separated from each other, the circuit board 220 is disposed in the first chamber 201, and the another coil module 250 is disposed in the second chamber 203. This arrangement may separate the circuit board 220 from the other coil module 250 to prevent the other coil module 250 from adversely affecting the electronic components on the circuit board 220 during operation. For example, this structure can reduce the influence of heat generated when the other coil module 250 operates on the electronic components of the circuit board 220. In some embodiments, the first chamber 201 and the second chamber 203 may be completely isolated, i.e., the first chamber 201 and the second chamber 203 are not in communication. In other embodiments, the first chamber 201 and the second chamber 203 may be in communication, and the partition 240 may reduce the influence of the other coil module 250 on the electronic components of the circuit board 220 during operation. Further, in some embodiments, the partition 240 may be coated with a material with better heat insulation, such as glass fiber or asbestos, so as to further reduce the influence of the heat generated by the other coil module 250 on the electronic components of the circuit board 220.
