DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] like Figure 1-4 As shown, 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 limiting member 140 and a second limiting member 150 .

[0025] The base 110 is used to carry the support member 120 and the wireless charging module 130. The base 110 has a relatively large bottom area, so that the base 110 is relatively 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 are surrounded to form a receiving cavity 110a. The receiving cavity 110a can be used to accommodate some other components of the wireless charging device 100. The upper shell 111 and the lower shell 112 are detachably connected, which is convenient for assembling the base 110 and also convenient for repairing the components in the base 110. The material of the upper shell 111 and the lower shell 112 can be plastic, so as to reduce the weight of the base 110 and have insulation. The material of the upper shell 111 and the lower shell 112 can be metal, so that the base 110 has a higher strength and a longer service life.

[0026] The support member 120 is used to support the wireless charging module 130, and the wireless charging module 130 is used to wirelessly charge the electronic device, which can be exemplarily a mobile phone, a smart watch, a headset, a power bank, etc. The wireless charging module 130 transmits electromagnetic waves to the electronic device, and the electronic device converts the electromagnetic waves into electrical energy, thereby eliminating the need for a power cord to achieve wireless charging. Optionally, a magnetic suction component can be integrated in the wireless charging module 130, so that the wireless charging module 130 can use the magnetic suction component to achieve precise alignment with the electronic device, thereby improving the charging efficiency. In addition to precise alignment, the magnetic suction component can also ensure that the electronic device will not be offset due to vibration during charging, thereby maintaining the electronic device in the best charging state.

[0027] The wireless charging module 130 is disposed on the support 120 and outside the accommodating cavity 110a, that is, the wireless charging module 130 and the base 110 are spaced apart in the height direction, and the wireless charging module 130 does not need to be disposed on the base 110, thereby reducing the size of the base 110 in the horizontal direction, so that the wireless charging device 100 does not occupy too much area when placed. Moreover, since the wireless charging module 130 is suspended, the heat dissipation performance of the wireless charging module 130 is better, and thus the charging efficiency is higher.

[0028] The support member 120 is fixed to the base 110 to ensure its own stability. Optionally, the support member 120 has a plug end 120a, which is one end of the support member 120 for being installed with 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.

[0029] The first stopper 140 is disposed in the accommodating cavity 110a, and the first stopper 140 is connected to the support member 120 and the upper shell 111 to fix the support member 120 to the upper shell 111. Exemplarily, the first stopper 140 can be a first nut, an external thread is provided on the plug-in end 120a, the first nut is threadedly connected with the external thread on the plug-in end 120a, and the first nut abuts against the upper shell 111, thereby fixing the support member 120 to the upper shell 111. Alternatively, the first stopper 140 can be a first latch, a first latch hole is provided on the plug-in end 120a, the first latch is inserted into the first latch hole, and the first latch abuts against the upper shell 111, thereby fixing the first support member 120 to the upper shell 111.

[0030] The second stopper 150 is connected to the support member 120 and the lower shell 112 to stop the support member 120. When the plug end 120a is located in the accommodating cavity 110a, the second stopper 150 is located in the accommodating cavity 110a. When the plug end 120a partially extends out of the accommodating cavity 110a, the second stopper 150 is located outside the accommodating cavity 110a.

[0031] 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 be doubly fixed, 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.

[0032] like Figure 5 As shown, in some embodiments, the plug end 120a is inserted into the lower shell 112, the second stopper 150 is disposed outside the accommodating cavity 110a, and the second stopper 150 fixes the support member 120 to the lower shell 112. Exemplarily, the second stopper 150 may be a second nut, which is threadedly engaged with the external thread on the plug end 120a and abuts against the lower shell 112, thereby fixing the support member 120 to the lower shell 112. Alternatively, the second stopper 150 may be a second latch, a second latch hole is disposed on the plug end 120a, the second latch is inserted into the second latch hole, and the second latch abuts against the lower shell 112, thereby fixing the first support member 120 to the lower shell 112. Optionally, a groove may 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 resist the bottom of the groove.

[0033] like Figure 6-9As shown, in some embodiments, the plug end 120a is located in the accommodating cavity 110a, the second stopper 150 is disposed in the accommodating cavity 110a and fixed to the lower shell 112, and the second stopper 150 abuts against the support member 120. Therefore, it is not necessary to provide a through hole on the lower shell 112 for the plug end 120a to pass through, thereby improving the sealing performance of the lower shell 112.

[0034] In some embodiments, the plug end 120a is a tubular structure, and a tube wall on one side of the plug end 120a has a first threading hole 120b that penetrates radially, and the first threading hole 120b is for the wire in the base 110 to pass through. Optionally, the plug end 120a is a round tube, a square tube, an oval tube, etc.

[0035] 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 attached to the inner wall of the plug-in 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-in end 120a. The second limiting rib 152 is disposed on the lower shell 112 and is attached to the outer wall of the plug-in 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-in end 120a. By sandwiching the plug-in 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 limit the plug-in end 120 a together.

[0036] It is understandable that when the plug end 120a is a round tube, the first limiting rib 151 and the second limiting rib 152 are arc-shaped, and when the plug end 120a is a square tube, the first limiting rib 151 and the second limiting rib 152 are straight or broken line-shaped. When the plug end 120a is an elliptical tube, the first limiting rib 151 and the second limiting rib 152 are curved.

[0037] 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 .

[0038] The first reinforcing rib 153 is disposed on the side of the first limiting rib 151 away from the second limiting rib 152, and the first reinforcing rib 153 is connected to the first limiting rib 151. The first reinforcing rib 153 can improve the structural strength of the first limiting rib 151, so that the first limiting rib 151 has a better limiting effect 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, so as to make the strength of each part of the first limiting rib 151 as close as possible. Optionally, the number of the first reinforcing rib 153 is multiple, and the multiple first reinforcing ribs 153 are evenly spaced and disposed on the first limiting rib 151 along the circumference of the first limiting rib 151.

[0039] The annular rib 154 is disposed 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. It is sufficient that the annular rib 154 is connected end to end to form a continuous closed ring shape. The annular rib 154 is annular in shape, so its own strength is relatively high.

[0040] The second reinforcing rib 155 is disposed between the second limiting rib 152 and the annular rib 154, and the second reinforcing rib 155 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, so that the strength of the integral structure is higher. Optionally, there are multiple second reinforcing ribs 155, and the multiple second reinforcing ribs 155 are evenly spaced, so that the strength of each part of the integral structure is relatively close.

[0041] The first connection column 156 is disposed on the lower shell 112 and connected to the annular rib 154. The first connection column 156 is provided with a screw hole for connecting to the upper shell 111. The first connection column 156 can further enhance the structural strength of the overall structure. At the same time, since the first connection column 156 can be connected to the upper shell 111 by screws, the first connection column 156 can specifically strengthen the portion where the upper shell 111 is connected to the plug-in end 120a and the portion where the lower shell 112 is connected to the plug-in end 120a, thereby avoiding deformation of the portion where the upper shell 111 is connected to the plug-in end 120a and the portion where the lower shell 112 is connected to the plug-in end 120a as much as possible, and enhancing 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 set between the annular ribs 154 and serve as a part of the annular ribs 154. 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 achieve a similar effect of improving strength.

[0042] like Figure 10-11 As shown, in some embodiments, the upper shell 111 is provided with a plug hole 111a, the plug end 120a is inserted into the plug hole 111a, and the plug end 120a and the plug hole 111a are limitedly matched to limit the rotation of the support member 120 relative to the base 110. Exemplarily, the plug hole 111a has a non-circular shape, for example, the plug hole 111a has an oblong, elliptical, rectangular, triangular, etc., and the projection shape of the plug end 120a in the plugging direction corresponds to the shape of the plug hole 111a, so that the plug end 120a is limited by the shape of the plug hole 111a.

[0043] like Figure 1 As shown, 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 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 arranged on the second rod 122, and the second charging module 132 is arranged on the third rod 123. The second rod 122 and the third rod 123 are both arranged at an angle to the first rod 121. Exemplarily, the second rod 122 and the third rod 123 are both arranged perpendicular to the first rod 121. The extension directions of the second rod 122 and the third rod 123 can be the same, opposite or arranged at an angle, and the second rod 122 and the third rod 123 can be located at the same height of the first rod 121, or at different heights of the first rod 121. The first rod 121 , the second rod 122 and the third rod 123 may be integrally formed or assembled separately.

[0044] 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 torque of the first charging module 131 and the second charging module 132 on the first rod 121 can at least partially offset each other.

[0045] Optionally, the first charging module 131 is used to charge a mobile phone, and the second charging module 132 is used to charge a watch, so the first charging module 131 is relatively large in size and heavy in weight, and the second charging module 132 is relatively small in size and light in weight. In addition, since the size of the mobile phone is relatively large, sufficient space needs to be reserved between the first charging module 131 and the first rod 121 and the base 110 for placing the mobile phone, that is, the distance between the first charging module 131 and the first rod 121 and the base 110 is relatively large.

[0046] Since 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 weight of the first charging module 131 is greater than that of the second charging module 132, the center of gravity of the whole composed of the support 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. At this time, if the connection position 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, which is not stable enough. 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 whole composed of the support member 120, the first charging module 131 and the second charging module 132 can be close 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 arranged on the support member 120 according to actual needs.

[0047] like Fig.12 As shown, in some embodiments, the support member 120 is a hollow structure, and the support member 120 has a first threading hole 120b, a second threading hole 122a, and a third threading hole 123a, and the first threading hole 120b is connected to the accommodating cavity 110a. Optionally, the first rod 121 has a first threading hole 120b, the second rod 122 has a second threading hole 122a, and the third rod 123 has a third threading hole 123a, and the first rod 121 is connected to the second rod 122 and the third rod 123.

[0048] like Figure 8-9 As shown, the wireless charging device 100 also includes an electric control board 180, a first wire 160 and a second wire 170. The electric control board 180 is used 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 according to the negotiation results. The shape of the circuit board is usually flat, and the shape of the base 110 is usually flat. The electric control board 180 is arranged in the accommodating cavity 110a to make full use of the space in the base 110 without significantly thickening the base 110. The first charging module 131 is installed on the first rod 121 and is arranged corresponding to the second threading hole 122a, and the second charging module 132 is installed on the second rod 122 and is arranged corresponding to the third threading hole 123a.

[0049] The first wire 160 is disposed in the support member 120, one end of the first wire 160 passes through the first threading hole 120b to be connected to the electric control board 180, and the other end passes through the second threading hole 122a to be connected to the first charging module 131. Optionally, the first wire 160 enters the first rod 121 through the first threading hole 120b, then enters the second rod 122 through the first rod 121, and passes through the second threading hole 122a.

[0050] The second wire 170 is disposed in the support member 120, one end of the second wire 170 passes through the first threading hole 120b to be connected to the electric control board 180, and the other end passes through the third threading hole 123a to be connected to the second charging module 132. Optionally, the second wire 170 enters the first rod 121 through the first threading hole 120b, then enters the third rod 123 through the first rod 121, and passes through the third threading hole 123a.

[0051] In this embodiment, the wiring is routed from the inside of the support member 120, making full use of the internal space of the support member 120, so that the volume of the wireless charging device 100 is small. In addition, the support member 120 can protect the first wire 160 and the second wire 170, prevent the first wire 160 and the second wire 170 from being worn, thereby increasing the service life of the first wire 160 and the second wire 170. Optionally, the support member 120 is made of metal, so that the service life of the support member 120 is longer, and it can play a certain shielding role on the first wire 160 and the second wire 170, reducing transmission interference.

[0052] like Figure 13-15 As shown, in some embodiments, the support member 120 includes a main body 124 and a cover 125. Optionally, part of the first rod 121, part of the second rod 122 and part of the third rod 123 form the main body 124, and another part of the first rod 121, another part of the second rod 122 and another part of the third rod 123 form the cover 125. The main body 124 is integrally formed, and the cover 125 is integrally formed, thereby simplifying the production process and maximizing the sealing effect. The support member 120 is combined by the main body 124 and the cover 125, so as to facilitate the installation and fixation of the first conductive wire and the second conductive wire 170 located inside the support member 120.

[0053] like Fig.14 As shown, the main body 124 is provided with a second connecting column 1241 and a limiting protrusion 1242, the limiting protrusion 1242 is provided corresponding to the second connecting column 1241, and a wire clamping groove 124b is formed between the limiting protrusion 1242 and the second connecting column 1241. By using the connecting column to form the wire clamping groove 124b, the connecting column can realize the function of the limiting protrusion 1242, so that there is no need to provide two limiting protrusions 1242, and only one limiting protrusion 1242 is required to be provided corresponding to the connecting column.

[0054] Optionally, the diameter of the second wire 170 is larger than that of the first wire 160, the first wire 160 is clamped in the clamping groove 124b, and the second wire 170 is closer to the cover 125 than the first wire 160. That is, when assembling the first wire 160 and the second wire 170, the first wire 160 is first clamped in the clamping groove 124b, and then the second wire 170 is pressed on the first wire 160, and finally the cover 125 is covered on the main body 124, and the cover 125 can press the second wire 170 to fix the second wire 170. It can be understood that since the diameter of the second wire 170 is larger than that of the first wire 160, the second wire 170 can easily press the first wire 160, thereby fixing the first wire 160. Moreover, compared with the thinner first wire 160, the cover 125 is easier to fix the thicker second wire 170. 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 .

[0055] like Figure 14-15 As shown, in some embodiments, the second connecting column 1241 is provided with a first positioning hole 124a, and the cover body 125 is provided with a first positioning column 1251, and the first positioning column 1251 is plugged and matched with the first positioning hole 124a. Generally speaking, in order to improve the sealing performance of the support member 120, an adhesive is provided between the main body 124 and the cover body 125. After the adhesive is applied between the main body 124 and the cover body 125, the main body 124 and the cover body 125 need to be continuously pressed until the adhesive is solidified, so the process is complicated. However, the main body 124 and the cover body 125 of this embodiment can be assembled through the first positioning column 1251 and the first positioning hole 124a. Therefore, after the adhesive is applied between the main body 124 and the cover body 125, the main body 124 and the cover body 125 can be directly combined together and left to stand, waiting for the adhesive to completely solidify, without having to continuously press the main body 124 and the cover body 125, and the process is relatively simple.
