When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a wireless charging device 100, which includes a charging base 10, a bracket 20, a first charging sub-base 30 and a second charging sub-base 40. The bracket 20 is hinged to the charging base 10, and the bracket 20 is provided with an avoidance space 21. The first charging sub-base 30 is hinged to the bracket 20, and the second charging sub-base 40 is hinged to the bracket 20; wherein, the wireless charging device 100 has a folding state. When the wireless charging device 100 is in the folding state, the charging base 10 and the first charging sub-base 30 are respectively located on opposite sides of the bracket 20, and the second charging sub-base 40 is located in the avoidance space 21.

[0022] It should be noted that the charging base 10, the first charging sub-base 30 and the second charging sub-base 40 can all realize the wireless charging function. The wireless charging coil, PCB board and its structural layout and line routing required to realize the wireless charging function can be implemented with reference to the existing technology and will not be repeated here.

[0023] In this embodiment, the power supply interface of the wireless charging device 100 is a Type-C interface, which is provided on the charging base 10. The power supply interface is electrically connected to the circuit board inside the charging base 10 so as to be electrically connected to the external power supply through the power supply interface, thereby powering on the wireless charging device 100.

[0024] In this embodiment, the wireless charging device 100 can charge mobile phones and wireless headphones through the charging base 10 and the first charging sub-base 30, and charge smart watches and smart bracelets through the second charging sub-base 40, so as to meet the user's diverse charging needs at the same time. Figure 1 As shown, the charging base 10 and the first charging sub-base 30 can be folded to the opposite sides of the bracket 20, and the second charging sub-base 40 can be folded into the avoidance space 21 of the bracket 20, so that the volume of the wireless charging device 100 in the folded state is smaller, making it easier for users to store and carry. Figure 6As shown, when using the wireless charging device 100, the user rotates the bracket 20 to rotate the bracket 20 around the hinge point between the bracket 20 and the charging base 10 to unfold, rotates the first charging sub-base 30 to rotate the first charging sub-base 30 around the hinge point between the bracket 20 and the charging base 10 to unfold, and rotates the second charging sub-base 40 to rotate the second charging sub-base 40 around the hinge point between the bracket 20 and the charging base 10 to unfold, thereby unfolding the wireless charging device 100.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, the charging base 10 and the first charging sub-base 30 are respectively hingedly connected to opposite radial sides of the bracket 20. Specifically, the hinge point between the charging base 10 and the bracket 20 can be considered the first hinge point, and the hinge point between the first charging sub-base 30 and the bracket 20 can be considered the second hinge point. The first hinge point, the center of the bracket 20, and the second hinge point are all located on the same straight line. This arrangement allows the first charging sub-base 30 to flip over above the charging base 10 when the wireless charging device 100 is in use, so that a smart device (such as a mobile phone or wireless headphones) placed on the first charging sub-base 30 is located above the charging base 10. This ensures that the center of gravity of the entire device is located in the normal direction of the charging base 10, preventing the wireless charging device 100 from tipping over during use.

[0026] For example: when the user uses the mobile phone while charging (such as watching videos, etc.), the bracket 20 can be flipped to a position perpendicular to the charging base 10, and the first charging sub-base 30 can be flipped to a position 180 degrees with the bracket 20, that is, the charging base 10, the bracket 20, and the first charging sub-base 30 are in an "L-shape" as a whole. At this time, the mobile phone placed on the first charging sub-base 30 for charging is located above the charging base 10, and the mobile phone screen is parallel to the ground, which is convenient for the user to use the mobile phone; when the user does not need to use the mobile phone while charging, the bracket 20 can be flipped to a position at an acute angle to the charging base 10, and the first charging sub-base 30 can be flipped to a position at an acute angle to the bracket 20, and the charging base 10, the bracket 20, and the first charging sub-base 30 are in a "Z-shape" as a whole.

[0027] In other embodiments, the first charging sub-base 30 and the second charging sub-base 40 may be hinged to opposite sides of the bracket 20 in its radial direction, and the hinge point of the charging base 10 and the bracket 20 is located on the mid-perpendicular line of the first charging sub-base 30 and the second charging sub-base 40. That is, when using the wireless charging device 100 for charging, the bracket 20 is flipped to a position perpendicular to the charging base 10, and the first charging sub-base 30 and the second charging sub-base 40 are flipped to a position 180 degrees with the bracket 20, that is, the bracket 20, the first charging sub-base 30, and the second charging sub-base 40 are overall in a "T shape", and the first charging sub-base 30 and the second charging sub-base 40 are at the same height, so that the center of gravity of the wireless charging device 100 is stable.

[0028] like Figure 2 and Figure 4 As shown, in this embodiment, the avoidance space 21 runs through opposite sides of the bracket 20, that is, the bracket 20 is arranged in an annular shape, and the avoidance space 21 is a through hole formed in the inner wall of the bracket 20. This can reduce the weight of the bracket 20 and facilitate the portability of the wireless charging device 100. In addition, when a smart device is placed on the charging base 10 for charging and the bracket 20 has not been flipped to a position perpendicular to the charging base 10, the provision of the avoidance space 21 can stagger the bracket 20 and the smart device placed on the charging base 10 to avoid interference.

[0029] like Figure 2-Figure 5 As shown, in this embodiment, the bracket 20 includes a first curved member 22, a second curved member 23, and a third curved member 24. The two ends of the first curved member 22 are respectively hinged to the charging base 10 and the first charging sub-base 30, the two ends of the second curved member 23 are respectively hinged to the charging base 10 and the second charging sub-base 40, and the two ends of the third curved member 24 are respectively hinged to the first charging sub-base 30 and the second charging sub-base 40. The first curved member 22, the second curved member 23, and the third curved member 24 are enclosed to form the avoidance space 21. Among them, the first curved member 22, the second curved member 23, and the third curved member 24 are all assembled by two half shells to facilitate the assembly of the first curved member 22, the second curved member 23, and the third curved member 24 with the charging base 10, the first charging sub-base 30, and the second charging sub-base 40.

[0030] like Figure 2-Figure 5 As shown, in this embodiment, the top of the charging base 10 is provided with a first hinge portion 11 protruding toward the bracket 20. The first hinge portion 11 is hingedly connected to the first curved member 22 and the second curved member 23, respectively. The bottom of the first charging sub-base 30 is provided with a second hinge portion 31 protruding toward the bracket 20. The second hinge portion 31 is hingedly connected to the first curved member 22 and the third curved member 24, respectively. The first curved member 22 and the second curved member 23 are hingedly connected to opposite sides of the first hinge portion 11, respectively, to facilitate assembly of the charging base 10 with the first curved member 22 and the second curved member 23; the first curved member 22 and the third curved member 24 are hingedly connected to opposite sides of the second hinge portion 31, respectively, to facilitate assembly of the first charging sub-base 30 with the first curved member 22 and the third curved member 24.

[0031] like Figure 2-Figure 5As shown, in this embodiment, the second charging sub-base 40 includes a charging body 41 and a connecting base 42. The connecting base 42 is hinged to the bracket 20. The connecting base 42 has a spherical portion 421, and the charging body 41 has a spherical groove 411. The spherical portion 421 is hinged in the spherical groove 411. That is, the hinged connection between the spherical portion 421 and the spherical groove 411 enables the charging body 41 to rotate about the axis of the connecting base 42. The second curved member 23 and the third curved member 24 are respectively hinged on opposite sides of the connecting base 42. The charging body 41 is used to charge the smartwatch.

[0032] It is understandable that the charging part of a smart watch is usually located on the back of the watch body, and because of the strap, the smart watch cannot be placed flat on the charging body 41. Therefore, the wireless charging device 100 of this embodiment can rotate the charging body 41 until the plane with the charging function is parallel to the ground, and place the smart watch on the charging body 41 so that the back of the smart watch body is in contact with the plane with the charging function of the charging body 41. The strap of the smart watch wraps around the charging body 41 to fix the smart watch on the charging body 41 for charging.

[0033] like Figure 1 and Figure 4 As shown, in this embodiment, the first charging sub-base 30 has a charging surface 32. When the wireless charging device 100 is in the folded state, the charging surface 32 is located on the side of the first charging sub-base 30 facing away from the bracket 20. The wireless charging device 100 occupies minimal space when folded. If the user only needs to charge a mobile phone, the wireless charging device 100 can be left unfolded and the mobile phone can be charged by placing it on the charging surface 32 of the first charging sub-base 30.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, a magnetic member 33 is provided within the first charging sub-base 30 at a position corresponding to the charging plane 32. The magnetic member 33 provides magnetic force to the charging plane 32. When the first charging sub-base 30 is unfolded and the charging plane 32 is not parallel to the ground, the magnetic member 33 attracts the smart device placed on the charging plane 32, thereby preventing the smart device from falling off the first charging sub-base 30. The magnetic attraction also facilitates the user to remove and place the smart device. The number of magnetic members 33 is multiple, and the multiple magnetic members 33 are evenly arranged along the periphery of the charging plane 32 to ensure uniform magnetic force on the charging plane 32.

[0035] like Figure 3 and Figure 4As shown, in this embodiment, the bottom surface of the charging base 10 is provided with an anti-slip member 12. It is understood that when the wireless charging device 100 falls to one side, a force component is generated in the horizontal direction. Therefore, the anti-slip member 12 increases the friction between the bottom surface of the charging base 10 and the surface on which the charging base 10 is placed, thereby counteracting part of the horizontal force component generated by the falling wireless charging device 100, thereby improving the stability of the wireless charging device 100. The anti-slip member 12 is made of silicone.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
