[0046] See attached Figure 1 -Attached Figure 15 A portable multi-purpose wireless charging device includes a base shell 1, a circuit board 2, a first magnetic charging unit 3, a turntable 4 and a support assembly 5; a accommodating cavity 10 is provided inside the base shell 1; the circuit board 2 is installed in the accommodating cavity 10; the first magnetic charging unit 3 is installed on the top of the base shell 1 and is electrically connected to the circuit board 2, and the first magnetic charging unit 3 magnetically attracts the back of the mobile phone for power supply; the turntable 4 is rotatably installed at the bottom of the base shell 1, and there is damping between the turntable 4 and the base shell 1; the support assembly 5 includes a linkage rod 51 and a base 52, and the linkage rod 51 is hinged with the turntable 4 and the base 52 at both ends, so that the support assembly 5 has a folded state and an unfolded state.

[0047] Specifically, under normal circumstances, the support assembly 5 is in a folded state and fits closely to the base shell 1 , so that the overall volume is small and convenient for users to carry outside.

[0048] Before use, power is supplied to the circuit board 2 so that the first magnetic charging unit 3 is powered.

[0049] During use, if the support assembly 5 is in a folded state, the first unit is in a flat state, and the user can directly adsorb and fix the first magnetic charging unit 3 on the back of the mobile phone for charging; if the user needs to watch the mobile phone while charging, the base 52 is placed on the desktop, and the base shell 1 is pulled to adjust the support assembly 5 to the unfolded state for use as a stand. At this time, the user can control the unfolding range to adjust the height position of the mobile phone, or rotate the base shell 1 around the turntable 4 to adjust the angle position of the mobile phone; and since the linkage rod 51 is damped and hinged with the turntable 4 and the base 52, the support assembly 5 can stay in the current position after being unfolded to the appropriate range. Similarly, since the turntable 4 and the base shell 1 are damped, it can also stay in the current position after rotation to prevent the mobile phone from shaking.

[0050] In summary, the present invention designs a base shell 1 for mounting a circuit board 2 and a first magnetic charging unit 3, and installs a support assembly 5 on the base shell 1, so that the overall volume can be reduced when folded to improve portability, and the base shell 1 can be used as a stand after unfolding to improve ease of use; and since the unfolding range of the support assembly 5 and the rotation angle of the turntable 4 are adjustable, the orientation of the mobile phone can be accurately adjusted to meet usage needs, thereby improving the user experience.

[0051] See attached Figure 3 -Attached Figure 10 There are various ways of rotating the connection between the base shell 1 and the turntable 4, but the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, a rotation cavity 11 is provided at the bottom of the base shell 1, and a rotation port 110 connected to the outside world is provided on the bottom side of the rotation cavity 11. The turntable 4 is located at the rotation port 110, and a rotation block 40 is provided on the turntable 4. The rotation block 40 is rotatably connected to the rotation cavity 11 and has an interference fit.

[0052] Specifically, since the rotating block 40 and the rotating cavity 11 have an interference fit, they have damping. The user needs to apply a certain force to overcome the damping when rotating the turntable 4. When the user releases the turntable 4, the turntable 4 stops at the current position. At the same time, in order to ensure that the mobile phone can be placed stably, the damping force between the rotating block 40 and the rotating cavity 11 should be greater than the self-gravity of a conventional mobile phone or other electronic product.

[0053] See attached Figure 3 -Attached Figure 8 In the present invention, a mounting opening 100 is provided on the top of the base shell 1, connecting the accommodating cavity 10 with the outside world. The first magnetic charging unit 3 is arranged at the mounting opening 100 to close the accommodating cavity 10; a notch 111 connected to the accommodating cavity 10 is provided on the top side of the rotating cavity 11, and a pressure plate 112 for closing the rotating cavity 11 is installed at the notch 111.

[0054] Specifically, before assembly, ensure that the mounting port 100 and the notch 111 are both in the open state; during assembly, first place the rotating block 40 into the rotating cavity 11 through the mounting port 100, the accommodating cavity 10 and the notch 111, and place the turntable 4 at the rotating port 110; then install the pressure plate 112 to the notch 111 to enclose the rotating block 40, and then install the circuit board 2 into the accommodating cavity 10, and finally fix the first magnetic charging unit 3 to the mounting port 100; similarly, during disassembly, disassemble the first magnetic charging unit 3, the circuit board 2, the pressure plate 112 and the turntable 4 in turn; therefore, the above design facilitates overall disassembly and assembly, and improves production convenience and maintenance convenience.

[0055] See attached Figure 6 -Attached Figure 8The first magnetic charging unit 3 is an existing product and has various types, so the present invention does not limit it. For the convenience of understanding, in this embodiment, the first magnetic charging unit 3 includes a mounting base 30, a cover plate 31, a first induction coil 32 and a first magnetic ring 33. The mounting base 30 is arranged at the mounting port 100 to close the accommodating cavity 10. The first induction coil 32 and the first magnetic ring 33 are both fixed on the mounting base 30, and the first induction coil 32 is electrically connected to the circuit board 2. The cover plate 31 is fixed on the mounting base 30 and covers the first induction coil 32 and the first magnetic ring 33, and the outer side of the cover plate 31 is in contact with the back of the mobile phone.

[0056] Specifically, when the back of the mobile phone is attached to the outer side of the cover plate 31, the first magnetic ring 33 is attracted to the magnetic ring inside the mobile phone (not shown in the figure) to fix the mobile phone on the cover plate 31; and the first induction coil 32 corresponds to the charging coil inside the mobile phone (not shown in the figure). The circuit board 2 provides current to the first induction coil 32, and the first induction coil 32 transmits the electrical signal to the charging coil inside the mobile phone to charge the mobile phone; since the relevant charging technology belongs to the existing technology in this field, its specific principle will not be elaborated here.

[0057] It should be noted that, further, there are various ways to install the mounting base 30, the cover plate 31 and the pressure plate 112, for example, they can be fixed by screws or glue, or directly fastened, and this is not limited in the present invention.

[0058] See attached Figure 3 -Attached Figure 11 The present invention also includes a spring piece 6, which is provided with a raised clamping head 6k. There are multiple limit openings 4k in a circular array on the inner surface of the turntable 4, and a movable opening 112k is provided on the pressure plate 112; the spring piece 6 is installed on the pressure plate 112, and the clamping head 6k extends into the movable opening 112k. The clamping head 6k can be disengaged from or clamped into any limit opening 4k one by one as the turntable 4 rotates, and when the clamping head 6k clamps the limit opening 4k, the spring piece 6 is in the initial state; the rotating block 40 and the rotating cavity 11 have an interference fit or a clearance fit.

[0059] Specifically, under normal circumstances, the spring piece 6 is in the initial state, and the clamping head 6k is clamped to the limiting opening 4k to provide damping to limit the rotation of the turntable 4.

[0060] When the turntable 4 is rotated forcefully, the clamping head 6k moves upward to disengage from the current limit opening 4k, and squeezes the spring piece 6 to compress and store energy. Under the action of elastic potential energy, the clamping head 6k has a tendency to move downward. Continue to rotate the turntable 4 so that the clamping head 6k is aligned with the next limit opening 4k. At this time, the spring piece 6 releases energy to recover and drives the clamping head 6k to engage the limit opening 4k.

[0061] In summary, the coordinated use of the limit opening 4k, the clamping head 6k and the spring piece 6 can, on the one hand, provide damping for the turntable 4, and on the other hand, make a sound during the rotation of the turntable 4, which has the function of prompting and relieving pressure.

[0062] It should be noted that when a limit portion is designed, the rotating block 40 and the rotating cavity 11 can continue to use interference fit to increase the damping degree, or can use clearance fit to reduce the damping degree of the rotating block 40 and the rotating cavity 11, so as to facilitate the user to rotate the turntable 4; this is not restricted in the present utility model.

[0063] See attached Figure 7 -Attached Figure 12 The spring piece 6 is made of stainless steel so that the spring piece 6 has good deformation ability and recovery ability.

[0064] See attached Figure 7 -Attached Figure 12 The cross-section of the limit opening 4k is semicircular, and the cross-section of the clamping head 6k is also semicircular to adapt to the limit opening 4k. This design can reduce the force between the clamping head 6k and the limit opening 4k, ensuring that the clamping head 6k can be more easily disengaged and engaged with the limit opening 4k, preventing the turntable 4 from having difficulty in rotating.

[0065] See attached Figure 3 -Attached Figure 10 In order to improve practicality, the present invention also includes a second magnetic charging unit 7, which is installed at the bottom of the base shell 1 and electrically connected to the circuit board 2, and the bottom end of the second magnetic charging unit 7 extends through the turntable 4 to magnetically attract the back of the watch for power supply. The turntable 4 can also rotate relative to the second magnetic charging unit 7.

[0066] Specifically, during use, if the support component 5 is in a folded state, the base shell 1 is flipped over so that the second unit is facing upward and in a flat state, and the user can directly adsorb and fix the second magnetic charging unit 7 on the back of the watch for charging; if the user needs to charge the mobile phone and watch at the same time, the base 52 is placed against the desktop, and the base shell 1 is pulled to adjust the support component 5 to the unfolded state. After the support component 5 is unfolded, the second magnetic charging unit 7 arranged at the bottom of the base shell 1 is exposed, and the user can adsorb and fix the second magnetic charging unit 7 on the back of the watch.

[0067] Among them, since the turntable 4 can rotate relative to the second magnetic charging unit 7, the second magnetic charging unit 7 and the watch will not be affected during the process of adjusting the direction of the mobile phone; however, when adjusting the expansion range of the support assembly 5, it is necessary to avoid the linkage rod 51 swinging and abutting the watch.

[0068] See attached Figure 7 -Attached Figure 10The second magnetic charging unit 7 is an existing product and has various types, so the present invention does not limit it. For the convenience of understanding, in this embodiment, the second magnetic charging unit 7 includes a protrusion 71, a second induction coil 72 and a second magnetic ring 73. The protrusion 71 is installed at the bottom of the base shell 1, and the bottom end of the protrusion 71 extends through the turntable 4 to fit the back of the watch; the second induction coil 72 and the second magnetic ring 73 are both installed inside the protrusion 71, and the second induction coil 72 is electrically connected to the circuit board 2.

[0069] Specifically, when the back of the watch is attached to the protruding seat 71, the second magnetic ring 73 is attracted to the magnetic ring inside the watch (not shown in the figure) to fix the watch on the protruding seat 71; and the second induction coil 72 corresponds to the charging coil inside the watch (not shown in the figure). The circuit board 2 provides current to the second induction coil 72, and the second induction coil 72 transmits the electrical signal to the charging coil inside the watch to charge the watch; since the relevant charging technology belongs to the existing technology in this field, its specific principle will not be elaborated here.

[0070] It should be noted that there are various ways to fix the protrusion 71 to the base shell 1. For ease of understanding, in this embodiment, the top of the protrusion 71 is actually located in the rotating cavity and is integrally connected to the pressure plate 112 for fixation.

[0071] See attached Figure 4 -Attached Figure 6 A first protrusion 41 is provided on the turntable 4, a first notch 511 and a second protrusion 512 are respectively provided at the head and tail ends of the linkage rod 51, and a second notch 520 is provided on the base 52; the first notch 511 is sleeved with the first protrusion 41, and a first shaft rod 5110 is installed at the first notch 511, and the first shaft rod 5110 is rotatably connected to the first protrusion 41 and has an interference fit to provide damping; the second notch 520 is sleeved with the second protrusion 512, and a second shaft rod 5200 is installed at the second notch 520, and the second shaft rod 5200 is rotatably connected to the second protrusion 512 and has an interference fit to provide damping.

[0072] Specifically, when the support assembly 5 is in a folded state, the second magnetic charging unit 7, the linkage rod 51 and the base 52 avoid each other to prevent the support assembly 5 from blocking the second magnetic charging unit 7; and the coordinated use of the first protrusion 41, the first recess 511 and the second recess 520 of the second protrusion 512 enables the linkage rod 51 and the base 52 to abut against the chassis after the support assembly 5 is folded, so as to further reduce the overall volume.

[0073] See attached Figure 1 -Attached Figure 5 and attached Figure 13 -Attached Figure 15The linkage rod 51 and the base 52 are both annular in design, and the inner ring diameter of the linkage rod 51 is larger than the outer ring diameter of the second magnetic charging unit 7, and the outer ring diameter of the linkage rod 51 is smaller than the inner ring diameter of the base 52.

[0074] Specifically, when the support assembly 5 is in a folded state, the linkage rod 51 fits the turntable 4 and surrounds the second magnetic charging unit 7, and the base 52 fits the turntable 4 and surrounds the linkage rod 51 to improve the overall neatness and aesthetics; at the same time, the annular linkage rod 51 and the base 52 have strong pressure resistance, which can improve the support stability.

[0075] See attached Figure 9 and attached Figure 14 The base 52 is made of magnetic material or a magnetic block 521 is installed on the base 52; under this design, the base 52 can be magnetically fixed to an iron desktop or windowsill, so that the base shell 1 can be placed horizontally or vertically to adapt to a variety of usage scenarios, thereby improving convenience of use.

[0076] See attached Figure 5 -Attached Figure 8 In order to facilitate power supply to the circuit board 2, a charging port 12 is also installed on the base shell 1, and the charging port 12 is electrically connected to the circuit board 2; when in use, just use an electric wire to connect the socket and the charging port 12.

[0077] See attached Figure 3 -Attached Figure 10 The present invention further includes a battery 13 , which is installed in the base shell 1 and electrically connected to the circuit board 2 .

[0078] Specifically, when the charging port 12 is not in use, the battery 13 can directly power the circuit board 2, and then charge the mobile phone; when the battery 13 is used up, a wire is used to connect the socket and the charging port 12 to charge the battery 13 and power the circuit board 2; this design makes it convenient for users to carry this wireless charging device at any time and use it as a mobile power source.

[0079] It should also be noted that although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
