DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] As shown in Figures 1-4, a first aspect of an embodiment of the present application provides a wireless charging device 100, which includes a base 110, a support member 120, a wireless charging module 130, a first limiter 140 and a second limiter 150.

[0026] The base 110 is configured to carry the support member 120 and the wireless charging module 130. The base 110 has a relatively large bottom area, which makes the base 110 more stable when placed. The base 110 includes an upper shell 111 and a lower shell 112 connected to the upper shell 111. The upper shell 111 and the lower shell 112 together form a receiving cavity 110a. The receiving cavity 110a can be configured to accommodate some other components of the wireless charging device 100. The upper shell 111 and the lower shell 112 are detachably connected, which facilitates the assembly of the base 110 and the maintenance of the components in the base 110. The material of the upper shell 111 and the lower shell 112 can be plastic, which reduces the weight of the base 110 and has insulating properties. The material of the upper shell 111 and the lower shell 112 can be metal, which makes the base 110 stronger and has a longer service life.

[0027] The support member 120 is configured to support the wireless charging module 130, and the wireless charging module 130 is configured to wirelessly charge electronic devices, which can be, for example, mobile phones, smart watches, headphones, power banks, etc. The wireless charging module 130 transmits electromagnetic waves to the electronic devices, and the electronic devices convert the electromagnetic waves into electrical energy, thereby eliminating the need for a power cord and achieving wireless charging. Optionally, a magnetic component can be integrated into the wireless charging module 130, so that the wireless charging module 130 can use the magnetic component to achieve precise alignment with the electronic device, thereby improving charging efficiency. In addition to precise alignment, the magnetic component can also ensure that the electronic device will not be offset due to vibration during charging, thereby maintaining the electronic device in the optimal charging state.

[0028] The wireless charging module 130 is disposed on the support member 120 and outside the accommodating cavity 110a. This means that the wireless charging module 130 is spaced apart from the base 110 in the height direction. This eliminates the need for the wireless charging module 130 to be mounted on the base 110, thereby reducing the horizontal size of the base 110 and ensuring that the wireless charging device 100 does not occupy an excessive amount of space when placed. Furthermore, since the wireless charging module 130 is suspended in the air, it provides better heat dissipation, resulting in higher charging efficiency.

[0029] The support member 120 is mounted and fixed to the base 110 to ensure its stability. Optionally, the support member 120 has a plug end 120a, which is the end of the support member 120 configured to be mounted on the base 110. The plug end 120a is provided through the upper shell 111. It should be noted that the plug end 120a can extend into the accommodating cavity 110a without passing through the lower shell 112, or the plug end 120a can continue to pass through the lower shell 112 and be partially located outside the accommodating cavity 110a.

[0030] The first stopper 140 is disposed within the accommodating cavity 110a and is connected to the support member 120 and the upper shell 111 to secure the support member 120 to the upper shell 111. For example, the first stopper 140 may be a first nut having an external thread disposed on its plug-in end 120a. The first nut is threadedly engaged with the external thread on the plug-in end 120a and abuts against the upper shell 111, thereby securing the support member 120 to the upper shell 111. Alternatively, the first stopper 140 may be a first latch pin having a first latch pin hole disposed on its plug-in end 120a. The first latch pin is inserted into the first latch pin hole and abuts against the upper shell 111, thereby securing the first support member 120 to the upper shell 111.

[0031] The second stopper 150 is connected to the support member 120 and the lower housing 112 to limit the position of the support member 120. When the plug end 120a is located within the accommodating cavity 110a, the second stopper 150 is located within the accommodating cavity 110a. When the plug end 120a partially extends outside the accommodating cavity 110a, the second stopper 150 is located outside the accommodating cavity 110a.

[0032] In summary, the support member 120 of the embodiment of the present application is fixed to the upper shell 111 by the first limiting member 140, and is fixed to the lower shell 112 by the second limiting member 150. The support member 120 can achieve double fixation, thereby enhancing the connection strength between the support member 120 and the base 110, making it difficult for the support member 120 and the base 110 to loosen.

[0033] As shown in FIG5 , in some embodiments, the plug end 120a is inserted through the lower shell 112, and the second stopper 150 is disposed outside the accommodating cavity 110a. The second stopper 150 secures the support member 120 to the lower shell 112. For example, the second stopper 150 may be a second nut that is threadedly engaged with the external thread on the plug end 120a and abuts against the lower shell 112, thereby securing the support member 120 to the lower shell 112. Alternatively, the second stopper 150 may be a second latch pin. The plug end 120a is provided with a second latch pin hole. The second latch pin is inserted into the second latch pin hole and abuts against the lower shell 112, thereby securing the first support member 120 to the lower shell 112. Optionally, a groove can be provided at the bottom of the lower shell 112 to accommodate the second limiting member 150, so that the bottom of the lower shell 112 remains flat and ensures the stability of the base 110 when placed; the second limiting member 150 can support the bottom of the groove.

[0034] As shown in Figures 6-9, in some embodiments, the plug end 120a is located within the accommodating cavity 110a, and the second stopper 150 is disposed within the accommodating cavity 110a and fixed to the lower shell 112. The second stopper 150 abuts against the support member 120. Therefore, it is not necessary to define a through hole in the lower shell 112 for the plug end 120a to pass through, thereby improving the sealing performance of the lower shell 112.

[0035] In some embodiments, the plug end 120a is a tubular structure, and a first threading hole 120b is radially penetrated on the wall of one side of the plug end 120a for the wire in the base 110 to pass through the first threading hole 120b. Optionally, the plug end 120a is a round tube, a square tube, an oval tube, etc.

[0036] The second limiting member 150 includes a first limiting rib 151 and a second limiting rib 152. The first limiting rib 151 is disposed on the lower shell 112 and is in contact with the inner wall of the plug end 120a. The first limiting rib 151 avoids the first threading hole 120b to prevent the first limiting rib 151 from blocking the first threading hole 120b from the inside of the plug end 120a. The second limiting rib 152 is disposed on the lower shell 112 and is in contact with the outer wall of the plug end 120a. The second limiting rib 152 avoids the first threading hole 120b to prevent the second limiting rib 152 from blocking the first threading hole 120b from the outside of the plug end 120a. By sandwiching the plug end 120 a between the first limiting rib 151 and the second limiting rib 152 , the first limiting rib 151 and the second limiting rib 152 can jointly limit the plug end 120 a .

[0037] It is understood that when the plug end 120a is a round tube, the first and second limiting ribs 151, 152 are arc-shaped, and when the plug end 120a is a square tube, the first and second limiting ribs 151, 152 are straight or broken line-shaped. When the plug end 120a is an oval tube, the first and second limiting ribs 151, 152 are curved.

[0038] In some embodiments, the second limiting member 150 further includes a first reinforcing rib 153 , an annular rib 154 , a second reinforcing rib 155 and a first connecting column 156 .

[0039] The first reinforcing rib 153 is disposed on a side of the first limiting rib 151 facing away from the second limiting rib 152, and is connected to the first limiting rib 151. The first reinforcing rib 153 can improve the structural strength of the first limiting rib 151, thereby improving the limiting effect of the first limiting rib 151 on the support member 120. Optionally, the first reinforcing rib 153 can be disposed in the middle of the first limiting rib 151, and the first reinforcing rib 153 extends toward the center of the circle corresponding to the first limiting rib 151, thereby ensuring that the strength of each part of the first limiting rib 151 is as close as possible. Optionally, there are multiple first reinforcing ribs 153, and the multiple first reinforcing ribs 153 are evenly spaced along the circumference of the first limiting rib 151.

[0040] The annular rib 154 is provided on the lower shell 112 and surrounds the second limiting rib 152. The shape of the annular rib 154 can be, for example, a circular ring, a square ring, an elliptical ring, etc., as long as the annular ribs 154 are connected end to end to form a continuous closed ring shape. The annular rib 154 has a high strength due to its annular shape.

[0041] The second reinforcing rib 155 is disposed between the second limiting rib 152 and the annular rib 154, and connects the second limiting rib 152 and the annular rib 154. The second reinforcing rib 155 connects the second limiting rib 152 and the annular rib 154 into an integral structure, thereby enhancing the strength of the integral structure. Optionally, there are multiple second reinforcing ribs 155, and the multiple second reinforcing ribs 155 are evenly spaced, thereby ensuring that the strength of the overall structure is relatively uniform.

[0042] The first connecting post 156 is disposed on the lower shell 112 and connected to the annular rib 154. The first connecting post 156 is provided with a screw hole configured to connect to the upper shell 111. The first connecting post 156 can further enhance the structural strength of the overall structure. At the same time, because the first connecting post 156 can be connected to the upper shell 111 by screws, the first connecting post 156 can specifically strengthen the connection between the upper shell 111 and the plug end 120a and the connection between the lower shell 112 and the plug end 120a, thereby minimizing deformation of the connection between the upper shell 111 and the plug end 120a and the connection between the lower shell 112 and the plug end 120a, thereby strengthening the limiting effect of the upper shell 111 and the lower shell 112 on the support member 120. It should be noted that the first connecting column 156 can also be arranged between the annular ribs 154 and serve as a part of the annular ribs 154, and the second reinforcing ribs 155 can also be directly connected to the first connecting column 156 instead of being connected to the annular ribs 154. The above settings can all achieve a similar effect of improving strength.

[0043] As shown in Figures 10-11, in some embodiments, the upper shell 111 is provided with an insertion hole 111a, and the insertion end 120a is inserted into the insertion hole 111a, and the insertion end 120a and the insertion hole 111a are limitedly matched to limit the rotation of the support member 120 relative to the base 110. Exemplarily, the shape of the insertion hole 111a is non-circular, for example, the shape of the insertion hole 111a is an oblong, elliptical, rectangular, triangular, etc., and the projection shape of the insertion end 120a in the insertion direction corresponds to the shape of the insertion hole 111a, so that the position is limited by the shape of the insertion end 120a and the insertion hole 111a.

[0044] As shown in FIG1 , in some embodiments, the support member 120 includes a first rod 121, a second rod 122, and a third rod 123. The first rod 121 has a plug-in end 120a, and the second rod 122 and the third rod 123 are both connected to the first rod 121. The wireless charging module 130 includes a first charging module 131 and a second charging module 132. The first charging module 131 is disposed on the second rod 122, and the second charging module 132 is disposed on the third rod 123. The second rod 122 and the third rod 123 are both disposed at an angle to the first rod 121. For example, the second rod 122 and the third rod 123 are both disposed perpendicular to the first rod 121. The second rod 122 and the third rod 123 can extend in the same direction, in opposite directions, or at an angle. The second rod 122 and the third rod 123 can be located at the same height as the first rod 121, or at different heights. The first rod 121 , the second rod 122 and the third rod 123 may be integrally formed or assembled separately.

[0045] Optionally, the first charging module 131 and the second charging module 132 are disposed on two sides of the first rod 121 that are away from each other, so that the torques exerted by the first charging module 131 and the second charging module 132 on the first rod 121 can at least partially offset each other.

[0046] Optionally, the first charging module 131 is configured to charge a mobile phone, and the second charging module 132 is configured to charge a watch. Therefore, the first charging module 131 is relatively large and heavy, while the second charging module 132 is relatively small and light. Furthermore, since mobile phones are relatively large, sufficient space must be left between the first charging module 131, the first rod 121, and the base 110 to accommodate the mobile phone. In other words, the distance between the first charging module 131, the first rod 121, and the base 110 is relatively large.

[0047] Because the distance between the first charging module 131 and the base 110 is greater than the distance between the first charging module 131 and the base 110, the distance between the first charging module 131 and the first rod 121 is greater than the distance between the second charging module 132 and the first rod 121, and the first charging module 131 is heavier than the second charging module 132, the center of gravity of the entire structure consisting of the support member 120, the first charging module 131, and the second charging module 132 is biased toward the side where the first charging module 131 is located. In this case, if the connection point between the plug end 120a and the base 110 is located at the center of the base 110, the center of gravity of the wireless charging device 100 is biased toward the side where the first charging module 131 is located, making it less stable. If the connection position between the plug end 120a and the base 110 is offset from the center of the base 110 toward the side where the second charging module 132 is located, the center of gravity of the entire structure consisting of the support member 120, the first charging module 131, and the second charging module 132 can be closer to the center of the base 110, thereby making the wireless charging device 100 more stable. It should be noted that three or more charging modules can be installed on the support member 120 according to actual needs.

[0048] As shown in FIG12 , in some embodiments, the support member 120 is a hollow structure having a first threading hole 120 b, a second threading hole 122 a, and a third threading hole 123 a. The first threading hole 120 b communicates with the accommodating cavity 110 a. Alternatively, the first rod 121 has the first threading hole 120 b, the second rod 122 has the second threading hole 122 a, and the third rod 123 has the third threading hole 123 a. The first rod 121 communicates with the second rod 122 and the third rod 123.

[0049] As shown in Figures 8-9, the wireless charging device 100 also includes an electronic control board 180, a first wire 160, and a second wire 170. The electronic control board 180 is configured to negotiate charging parameters with the electronic device and control the output parameters of the first charging module 131 and the second charging module 132 based on the negotiation results. The circuit board is generally flat in shape, and the base 110 is also generally flat in shape. The electronic control board 180 is disposed within the accommodating cavity 110a to fully utilize the space within the base 110 without significantly increasing the thickness of the base 110. The first charging module 131 is mounted on the first rod 121 and is positioned corresponding to the second threading hole 122a. The second charging module 132 is mounted on the second rod 122 and is positioned corresponding to the third threading hole 123a.

[0050] The first wire 160 is disposed within the support member 120. One end of the first wire 160 passes through the first wire hole 120b to connect to the electronic control board 180, and the other end passes through the second wire hole 122a to connect to the first charging module 131. Optionally, the first wire 160 enters the first rod 121 through the first wire hole 120b, then enters the second rod 122 from the first rod 121, and exits through the second wire hole 122a.

[0051] The second wire 170 is disposed within the support member 120. One end of the second wire 170 passes through the first wire hole 120b to connect to the electronic control board 180, and the other end passes through the third wire hole 123a to connect to the second charging module 132. Optionally, the second wire 170 enters the first rod 121 through the first wire hole 120b, then enters the third rod 123 from the first rod 121, and exits through the third wire hole 123a.

[0052] This embodiment routes the wires through the interior of the support member 120, fully utilizing the internal space of the support member 120, thereby reducing the size of the wireless charging device 100. Furthermore, the support member 120 protects the first and second wires 160, 170 from wear and tear, thereby increasing the service life of the first and second wires 160, 170. Optionally, the support member 120 is made of metal, which extends the service life of the support member 120 and provides a certain degree of shielding for the first and second wires 160, 170, reducing transmission interference.

[0053] As shown in Figures 13-15, in some embodiments, the support member 120 includes a main body 124 and a cover 125. Optionally, a portion of the first rod 121, a portion of the second rod 122, and a portion of the third rod 123 form the main body 124, and another portion of the first rod 121, another portion of the second rod 122, and another portion of the third rod 123 form the cover 125. The main body 124 and the cover 125 are integrally formed, thereby simplifying the production process and maximizing the sealing effect. The support member 120 is assembled through the main body 124 and the cover 125, thereby facilitating the installation and fixation of the first and second conductive wires 170 located within the support member 120.

[0054] As shown in Figure 14, the main body 124 is provided with a second connecting post 1241 and a limiting protrusion 1242. The limiting protrusion 1242 is provided corresponding to the second connecting post 1241, and a wire-retaining groove 124b is formed between the limiting protrusion 1242 and the second connecting post 1241. By utilizing the connecting post to form the wire-retaining groove 124b, the connecting post can perform the function of the limiting protrusion 1242, thereby eliminating the need for two limiting protrusions 1242. Instead, only one limiting protrusion 1242 is required for each connecting post.

[0055] Optionally, the second wire 170 has a larger diameter than the first wire 160. The first wire 160 is secured to the wire retaining groove 124b, and the second wire 170 is positioned closer to the cover 125 than the first wire 160. That is, when assembling the first and second wires 160, the first wire 160 is first secured to the wire retaining groove 124b, the second wire 170 is then pressed against the first wire 160, and finally, the cover 125 is placed over the main body 124. The cover 125 presses against the second wire 170 to secure it. It will be appreciated that because the diameter of the second wire 170 is larger than that of the first wire 160, the second wire 170 can more easily press against the first wire 160, thereby securing it. Furthermore, the cover 125 is more easily able to secure the thicker second wire 170 than the thinner first wire 160. Optionally, other slot structures may be provided in the main body 124 to fix the first wire 160 or the second wire 170 , so as to achieve a better fixing effect of the first wire 160 or the second wire 170 .
