Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, specifically to a rotating wireless charging device with improved heat dissipation. Background Technology

[0002] Wireless charging devices have been widely accepted and recognized due to their convenience and speed. The principle of wireless charging is electromagnetic induction. Energy is transferred between the wireless charging device and the electronic device to be charged through a magnetic field. There is no need for a wired connection between the wireless charging device and the electronic device to be charged. It has a high degree of intelligence and has been widely used in various fields.

[0003] During operation, the heat generated by a wireless charging device is concentrated in the wireless charging coil and the circuit board. Since the wireless charging coil and the circuit board are usually integrated in the same wireless charging housing, the heat generated during operation is concentrated in the same space. The heat cannot be dissipated quickly and effectively, and the heat accumulation causes the temperature to rise, affecting the wireless charging efficiency. Therefore, there is an urgent need for a spin-out wireless charging device with improved heat dissipation to solve the above problems. Utility Model Content

[0004] In view of this, a spin-out wireless charging device with improved heat dissipation is provided, in which the magnetic induction coil and circuit board are cooled separately, making it easy to store and carry.

[0005] A heat-dissipating improved spin-out wireless charging device includes a first wireless charging module, a second wireless charging module, a third wireless charging module, a first housing, a second housing, a third housing, and a support body. The first wireless charging module includes a first magnetic induction coil and a first circuit board, which are separate. The first magnetic induction coil is located inside the first housing, and the first circuit board is located inside the support body. The second wireless charging module is located inside the second housing, and the third wireless charging module is located inside the third housing. The first housing is rotatably connected to the support body via a first pivot, and the second housing is rotatably connected to the support body via a second pivot. The support body is used for fixing. The first housing rotates horizontally around the first pivot in the plane containing the top surface of the support body, and the second housing rotates vertically around the second pivot. The bottom of the support body is provided with a support body receiving groove, and the third housing can be received in the support body receiving groove or can be rotatably removed from the support body receiving groove via a flexible conductive strip.

[0006] Furthermore, the second wireless charging module includes a second magnetic induction coil and a second circuit board, and the third wireless charging module includes a third magnetic induction coil and a third circuit board. The first and second rotating shafts are both hollow rotating shafts. The ribbon cable of the first magnetic induction coil is electrically connected to the first circuit board through the first rotating shaft. The ribbon cable of the second circuit board is electrically connected to the first circuit board through the second rotating shaft. The ribbon cable of the third circuit board is electrically connected to the first circuit board through the flexible conductive strip.

[0007] Furthermore, the upper surface of the first housing is provided with a plurality of support protrusions, which are distributed circumferentially at intervals.

[0008] Furthermore, the first rotating shaft is fixed to the edge of the support body and positioned near the edge of the first housing, so that when the first housing rotates horizontally in the plane containing the top surface of the support body, most of the bottom surface of the first housing can be separated from the top surface of the support body.

[0009] Furthermore, the position of the first rotating shaft is offset from the center of the first housing, and the position of the first rotating shaft is the rotation center axis of the first housing. The center of the first housing and the first rotating shaft determine a straight line on the plane of the first housing. The distance between the first rotating shaft and the farthest end of the first housing on the straight line is the rotation radius of the first housing. The rotation radius of the first housing is smaller than the top surface diameter of the support body.

[0010] Furthermore, the rotation center line of the first housing is perpendicular to the rotation center line of the second housing.

[0011] Furthermore, when the heat dissipation improved screw-out wireless charging device is in the storage state, the bottom of the second housing is provided with a clearance groove, and the second housing is flipped over by the second pivot to cover the first housing, with the first housing located in the clearance groove; the second housing is closed on the top of the support body, and the second housing is flush with the outer surface of the support body.

[0012] Furthermore, the first rotating shaft and the second rotating shaft are respectively provided with damping structures so that the first housing and the second housing can be positioned at any preset position when they rotate.

[0013] Furthermore, a clip is provided at the bottom of the support body, and the flexible conductive strip is fixed to the support body through the clip.

[0014] Furthermore, the support body is also provided with a USB interface for inputting external power.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] First, this improved heat dissipation screw-out wireless charging device avoids heat concentration during wireless charging by separating the first magnetic induction coil and the first circuit board. The first magnetic induction coil is located inside the first housing, and the first circuit board is located inside the support body. As the first housing rotates horizontally in the plane containing the top surface of the support body, most of the bottom surface of the first housing can be released from contact with the top surface of the support body. Therefore, most of the heat in the support body will not be conducted to the first housing, that is, most of the heat generated by the first circuit board will not be transferred to the first magnetic induction coil, which is beneficial to improving the wireless charging efficiency. In addition, multiple support protrusions are provided on the upper surface of the first housing to facilitate ventilation and heat dissipation.

[0017] Secondly, the bottom of the second housing of this heat dissipation improved rotary wireless charging device is provided with a clearance groove. After the second housing is flipped over by the second pivot, it covers the first housing. The first housing is located in the clearance groove, and the second housing is closed on the top of the support body. In addition, the bottom of the support body is provided with a support body receiving groove. The third housing can be accommodated in the support body receiving groove by means of a flexible conductive strip, so that the whole device has an integrated structure in the shape of a round box when stored, which is convenient to carry.

Finally, the third housing 3 is flipped out from the bottom of the support body 4, and the watch is placed on the third housing 3, and the third wireless charging module powers the watch.

[0026] Specifically, the second wireless charging module includes a second magnetic induction coil and a second circuit board, and the third wireless charging module includes a third magnetic induction coil and a third circuit board. The first rotating shaft 7 and the second rotating shaft 8 are both hollow rotating shafts. The ribbon cable of the first magnetic induction coil 5 is electrically connected to the first circuit board 6 through the first rotating shaft 7. The ribbon cable of the second circuit board is electrically connected to the first circuit board 6 through the second rotating shaft 8. The ribbon cable of the third circuit board is electrically connected to the first circuit board 6 through the flexible conductive strip 10.

[0027] Specifically, the upper surface of the first housing 1 is provided with a plurality of support protrusions 11, which are distributed circumferentially at intervals. In some specific embodiments, the plurality of support protrusions 11 support the earphone placed on the first housing 1, which facilitates ventilation of the earphone charging position and improves heat dissipation efficiency.

[0028] Specifically, the first rotating shaft 7 is fixed to the edge of the support body 4 and is located near the edge of the first housing 1, so that when the first housing 1 rotates horizontally in the plane containing the top surface of the support body 4, most of the bottom surface of the first housing 1 can be separated from the top surface of the support body 4.

[0029] More specifically, the position of the first rotating shaft 7 is offset from the center of the first housing 1. The position of the first rotating shaft 7 is the rotation center axis of the first housing 1. The center of the first housing 1 and the first rotating shaft 7 form a straight line on the plane of the first housing 1. The distance between the first rotating shaft 7 and the farthest end of the first housing 1 on the straight line is the rotation radius of the first housing 1. The rotation radius of the first housing 1 is smaller than the top surface diameter of the support body 4.

[0030] Specifically, the rotation center line of the first housing 1 is perpendicular to the rotation center line of the second housing 2.

[0031] Specifically, when the heat dissipation improved rotating wireless charging device is in the storage state, the bottom of the second housing 2 is provided with a relief groove 12, and the second housing 2 is flipped over by the second pivot 8 to cover the first housing 1, and the first housing 1 is located in the relief groove 12; the second housing 2 is closed on the top of the support body 4, and the second housing 2 is flush with the outer surface of the support body 4.

[0036] In summary, this improved heat dissipation screw-out wireless charging device avoids heat concentration during wireless charging by separating the first magnetic induction coil 5 and the first circuit board 6. The first magnetic induction coil 5 is located inside the first housing 1, and the first circuit board 6 is located inside the support body 4. Furthermore, because the first housing 1 rotates horizontally within the plane containing the top surface of the support body 4, most of the bottom surface of the first housing 1 can detach from the top surface of the support body 4. Therefore, most of the heat generated within the support body 4 is not conducted to the first housing 1, meaning that most of the heat generated by the first circuit board 6 is not transferred to the first magnetic induction coil 5, which is beneficial for improving wireless charging efficiency. Furthermore, multiple support protrusions 11 are provided on the upper surface of the first housing 1 to facilitate ventilation and heat dissipation, resulting in high heat dissipation efficiency.
