[0039] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present invention will be described in detail.
[0040] The embodiment of the present invention provides a wireless charger 1000, as Figures 1 to 5As shown, the wireless charger 1000 includes a base 100, an upper cover 200, and a support member 300. The base 100 includes a first substrate 110 and a first outer edge 120 surrounding the first substrate 110. The first outer edge 120 is located on one side of the first substrate 110 in the first direction, and the first substrate 110 is provided with a first charging coil 130. The upper cover 200 includes a second substrate 210 and a second outer edge 220 surrounding the second substrate 210. The second outer edge 220 is located on the side of the second substrate 210 close to the first outer edge 120, and the second outer edge 220 is attached to the first outer edge 120 so that the base 100 and the upper cover 200 jointly define a receiving cavity 400. The second substrate 210 is provided with a second charging coil 230. The support member 300 is disposed in the receiving cavity 400, and both ends of the support member 300 are rotatably connected to the base 100 and the upper cover 200 respectively, so that the upper cover 200 can move relative to the base 100 until the support member 300 is exposed to the outside. The rotation axes of both ends of the support member 300 are perpendicular to the first direction, and the support member 300 is provided with a third charging coil 310. The wireless charger 1000 of the present application has an unfolded state and a folded state. In the unfolded state, the upper cover 200 can move relative to the base 100 through the support member 300 to charge multiple mobile devices simultaneously. And the user can fold the wireless charger 1000 to reduce the overall occupied space and facilitate storage. Among them, in the folded state, the rotating joint of the support member 300 can be located inside the wireless charger 1000 to avoid being damaged by external bumps, so the wireless charger 1000 has stronger durability.
[0041] Specifically, in the folded state, the support member 300 can be hidden inside the receiving cavity 400 jointly defined by the base 100 and the upper cover 200. The receiving cavity 400 plays a protective role for the support member 300, which can prevent the key rotating connection parts on both sides of the support member 300 from being exposed to the outside, thereby reducing the probability of damage and improving the durability of the wireless charger 1000. Secondly, when the wireless charger 1000 is folded, the receiving cavity 400 is a closed space, and the whole of the support member 300 and the key rotating parts of the base 100 and the upper cover 200 are located in the closed receiving cavity 400. On the one hand, the overall appearance of the wireless charger 1000 looks more beautiful; on the other hand, it can also play a good role in dust prevention, maintain the cleanliness of the support member 300, and at the same time completely prevent small debris from entering the assembly gap, reducing the possibility of failure and making the wireless charger 1000 more reliable.
[0042] In this application, the wireless charger 1000 belongs to a three-in-one wireless charger 1000. It realizes wireless charging for multiple mobile devices through the first charging coil 130 arranged on the first substrate 110, the second charging coil 230 on the second substrate 210, and the third charging coil 310 of the support member 300. Exemplarily, the first charging coil 130 is used to power the earphone, the second charging coil 230 is used to power the mobile phone, and the third charging coil 310 is used to power the smartwatch. The user can directly place the mobile device at the corresponding position of the wireless charger 1000 for wireless charging.
[0043] Preferably, in order to make the mobile device fit firmly with the corresponding position, in this embodiment, magnetic members are also provided inside the first substrate 110, the second substrate 210, and the support member 300. When the mobile device approaches, the magnetic members can automatically adsorb to it, making the charging faster and more stable. Specifically, the magnetic members are magnets.
[0044] Refer to Figure 2 , an input interface 140 is also provided on the base 100. The input interface 140 is exposed outside the first outer edge 120, and the input interface 140 is electrically connected to the first charging coil 130, the second charging coil 230, and the third charging coil 310. With this design, only one charging cable needs to be connected to the input interface 140 to be able to supply power to the three coils (the first charging coil 130, the second charging coil 230, and the third charging coil 310) simultaneously, which is more efficient. Specifically, the input interface 140 can be interfaces such as USB, Type-C, Lightning, etc.
[0045] Refer to Figure 2 And Figure 6 , in an embodiment, the first substrate 110 includes a first end wall 111 adjacent to the first outer edge 120. A first mounting seat 111a is provided on the first end wall 111, and one end of the support member 300 is rotatably connected to the first mounting seat 111a; the second substrate 210 includes a second end wall 211 adjacent to the second outer edge 220. A second mounting seat 211a is provided on the second end wall 211, and the other end of the support member 300 is rotatably connected to the second mounting seat 211a. In the folded state, the second mounting seat 211a is located on the opposite side of the first mounting seat 111a. With such a setting, the first mounting seat 111a and the second mounting seat 211a can improve the connection reliability between the support member 300 and the base 100, and between the support member 300 and the upper cover 200, and the first mounting seat 111a and the second mounting seat 211a can also enhance the overall structural strength, making the rotation more stable when the upper cover 200 and the support member 300 move relative to the base 100.
[0046] In this embodiment, the first mounting base 111a and the base 100, and the second mounting base 211a and the upper cover 200 can be integrally formed or assembled. Exemplarily, the first mounting base 111a and the base 100, and the second mounting base 211a and the upper cover 200 are assembled. The connection method can be screw connection, snap connection, etc., which is not limited herein. By assembling and connecting, it is beneficial for the wireless charger 1000 to be assembled and more convenient for maintenance.
[0047] Referring to Figure 6 , in one embodiment, the wireless charger 1000 further includes two damping rotating shafts 500. The first mounting base 111a is connected to the support member 300 through one of the damping rotating shafts 500, and the second mounting base 211a is connected to the support member 300 through the other damping rotating shaft 500. The damping rotating shaft 500 can provide a damping force to maintain the relative positions of the support member 300, the base 100, and the upper cover 200, and prevent them from accidentally moving due to external force or gravity, so as to maintain the wireless charger 1000 in the unfolded state or the folded state. And in the unfolded state, through the damping rotating shaft 500, the user can also adjust the angle between the support member 300 and the upper cover 200 according to their own needs and preferences to meet personal usage habits, and the wireless charger 1000 has better use stability and flexibility.
[0048] It is worth mentioning that by implementing the above embodiments, when the wireless charger 1000 is in the unfolded state, the upper cover 200 can maintain a certain inclination angle relative to the base 100, which is beneficial for the upper cover 200 to supply power to the mobile device and the user to operate it. For example, when the upper cover 200 supplies power to a mobile phone, the mobile phone can be inclined relative to the horizontal desktop so that the user can view and operate the screen.
[0049] Referring to Figure 7 , in one embodiment, the first outer edge 120 includes a first end face 121 facing away from the first substrate 110 and a first outer peripheral face 122 connected to the first end face 121. A notch 123 is provided at the connection position between the first outer peripheral face 122 and the first end face 121, and the notch 123 is provided away from the rotation connection between the base 100 and the support member 300. The setting of the notch 123 facilitates the user to apply force to the upper cover 200, making it easier for the user to open the upper cover 200. And the notch 123 being away from the rotation connection between the base 100 and the support member 300 is more in line with the mechanical principle, and it is more labor-saving to open the upper cover 200.
[0050] Furthermore, referring to Figure 4 and Figure 7, at the connection position between the first outer peripheral surface 122 and the first end surface 121, a first annular chamfer 124 is further provided; the second outer edge 220 includes a second end surface 221 that can be attached to the first end surface 121, and a second outer peripheral surface 222 surrounding the second end surface 221. At the connection position between the second end surface 221 and the second outer peripheral surface 222, a second annular chamfer 223 is provided. The advantage of such a design is that, on the one hand, in the folded state, the first annular chamfer 124 and the second annular chamfer 223 can form a V-shaped opening at the edge where the first outer edge 120 and the second outer edge 220 are attached, increasing the contact surface with the fingers and further facilitating the user to open the upper cover body 200; on the other hand, the first annular chamfer 124 and the second annular chamfer 223 make the outer edge of the first outer edge 120 and the second outer edge 220 smoother and not scratch the hand, and the overall appearance of the wireless charger 1000 is also more beautiful.
[0051] Referring to Figure 4 and Figure 5 , in an embodiment, when the wireless charger 1000 is folded, the first outer edge 120 has a gradually narrowing trend in the direction away from the upper cover body 200, and the second outer edge 220 has a gradually narrowing trend in the direction away from the base 100. With such a setting, the overall occupied space of the wireless charger 1000 can be effectively saved, and it is more convenient to carry and store.
[0052] Specifically, both the first outer edge 120 and the second outer edge 220 are arc-shaped to increase the aesthetic appearance of the wireless charger 1000, and the rounded shape also conforms more to ergonomics, reducing the risk of damage when the wireless charger 1000 is accidentally collided.
[0053] Referring to Figure 8 , in an embodiment, the support member 300 includes a third substrate 320 and a rotating plate 330. Two ends of the third substrate 320 are respectively rotatably connected to the base 100 and the upper cover body 200. An accommodation groove 321 is provided on the third substrate 320. The second charging coil 230 is installed on the rotating plate 330, and the rotating plate 330 is rotatably connected to the groove wall of the accommodation groove 321 so that the rotating plate 330 can be rotated into or out of the accommodation groove 321. With such a setting, it is convenient to charge the mobile device.
[0054] Specifically, when the rotating plate 330 is rotated out of the accommodation groove 321, the rotating plate 330 can support the smart watch, and the smart watch can be charged in a flat placement manner; when the rotating plate 330 is rotated into the accommodation groove 321, the occupied space is reduced, which is beneficial to reducing the occupation of the internal space of the accommodation cavity by the support member 300 and has better adaptability.
[0055] Referring to Figure 9, in one embodiment, an anti-slip pad 150 is provided on a side of the first substrate 110 facing away from the first outer edge 120. With such an arrangement, when the base 100 is placed on a contact surface, the anti-slip pad 150 can increase the friction with the contact surface, and the wireless charger 1000 is less likely to be accidentally moved or knocked over during use.
[0056] Specifically, the anti-slip pad 150 is adhered to a side of the first substrate 110 facing away from the first outer edge 120. The first substrate 110 is provided with a limiting groove, and the anti-slip pad 150 is accommodated in the limiting groove to limit it.
[0057] In one embodiment, the wireless charger 1000 further includes three display screens (not shown in the figure). The three display screens are respectively installed on the base 100, the upper cover 200, and the support member 300. The display screens are used to display the charging status of the mobile device. With such an arrangement, the user can monitor the charging situation of the device in real time. This enables the user to conveniently understand the current charging progress of the device.
[0058] In one embodiment, the wireless charger 1000 further includes a heat sink (not shown in the figure). The heat sink is installed on the first substrate 110 and is disposed close to the first charging coil 130. When the wireless charger 1000 is working, certain heat will be generated, especially during the charging process. By disposing the heat sink close to the first charging coil 130, the heat dissipation efficiency can be improved, which helps to keep the temperature of the wireless charger 1000 within an appropriate range.
[0059] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
