These mobile devices are subject to the constraints of battery capacity and need to be charged in time to maintain the endurance.

[0003] In actual application, different mobile intelligent terminal devices have corresponding wireless chargers, for example, a smart phone has a corresponding wireless charging base; a wireless earphone needs to be placed in an earphone box and then mounted on a wireless charger to be charged; a smart wearable device needs to be connected to the contact end on the back of the wearable device body to realize charging connection. As can be seen, when people take these electronic products outside, they will need to carry multiple different wireless chargers at the same time to meet the charging needs of the corresponding electronic products.

[0004] At this time, the market has launched a charger integrated with multiple wireless charging functions. This multi-in-one wireless charger has multiple charging sites, allowing users to place corresponding electronic products on each charging site to achieve wireless charging. Since multiple electronic products need to be charged at the same time, the end surface of the charger for placing electronic products needs to be large enough. Generally, multiple charging modules are arranged along the length direction of the charger, thus limiting the overall shape of the charger and resulting in a large volume of the charger, which is not conducive to storage and carrying. In addition, this multi-in-one charger can only be placed flat on the desktop during use, resulting in that electronic products such as smart phones can only be placed flat on the charger for charging and cannot be used upright while charging.

[0005] Therefore, the multi-in-one wireless charger of the prior art has a large volume, which is not conducive to storage and carrying. When charging, electronic products such as smart phones need to be placed flat on the charger, and cannot be used upright while charging. Therefore, the current multi-in-one wireless charger cannot meet the travel and use requirements of users. SUMMARY

[0047] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0048] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0049] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0050] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0051] The charging module on the conventional all-in-one wireless charger generally includes a plurality of wireless charging modules, which are arranged in order on the surface of the charger so that the user can place the corresponding electronic products on each wireless charging module for charging.

[0052] It can be seen that, in order to support multiple electronic products to be charged at the same time, the end surface of the conventional all-in-one wireless charger for placing the electronic products needs to be large enough, so that multiple charging modules on the charger need to be arranged along the length direction of the charger, thereby limiting the overall shape of the charger and causing the charger to be large in size, which is not conducive to storage and carrying.

[0053] In addition, the conventional all-in-one wireless charger can only be placed flat on a desktop, and the electronic products such as a smart phone can only be placed flat on the wireless charger for charging, which will affect simultaneous use, which means that the smart phone cannot be used upright during charging, thereby reducing user experience.

[0054] Therefore, the embodiments of the present application provide a new all-in-one wireless charger, which is designed to be deformable and detachable for storage. When in use, the smart phone can be used upright while being charged, and the wireless charger can be stably fixed on a placing carrier by using a suction cup, so that the wireless charger is not easy to fall or shift. When stored, part of the wireless charging components can be separated and hidden in the charger, so as to effectively reduce the overall size and improve the use flexibility. Thus, the problems of the conventional all-in-one wireless charger, such as large size, poor storage and carrying, and inability to use the electronic products upright during charging, are solved. The all-in-one wireless charger will be described in detail.

[0055] Please refer to Figure 1 and Figure 2 The wireless charger of the embodiments of the present application at least includes a base 1 and a folding frame 2 arranged on the base 1.

[0056] The base 1 is internally provided with a main control board (not shown in the figure), and the outer periphery of the base 1 is provided with at least two electrical connection ports 11, which are electrically connected with the main control board.

[0059] The electric connection end of the second wireless charging module 4 is located on the upper surface of the base 1, and the folding frame 2 is used to stack the first wireless charging module 3 on the base 1 when the folding frame 2 is folded. In this embodiment, as shown in Figure 2 and Figure 3 , the first wireless charging module 3 preferably has the same shape and area as the base 1, and when the first wireless charging module 3 is stacked on the base 1, the two are combined into one, which is convenient for storage.

[0060] When charging, as shown in Figure 3 and Figure 4 , the folding frame 2 can be opened first, the first wireless charging module 3 can be moved away on the upper surface of the base 1, and the electric connection end of the second wireless charging module 4 can be exposed on the upper surface of the base 1. The wireless earphone can be placed in the earphone box and then placed on the electric connection end of the second wireless charging module 4 on the upper surface of the base 1 for wireless charging. When the charging is completed, as shown in Figure 2 , the wireless earphone box can be removed from the base 1, and the folding frame 2 can be folded, so that the first wireless charging module 3 is stacked on the base 1 to form an integrated whole with the base 1, which is convenient for reducing the overall volume of the charger and saving space.

[0061] Please refer to Figure 3 , Figure 4 and Figure 5 , the third wireless charging module 5 is a separate component and can be detachably connected to the electric connection port 11 on the outer periphery of the base 1. In use, the third wireless charging module 5 is installed on the side of the base 1, so that the smart wearable device can be sleeved on the third wireless charging module 5 for wireless charging, and will not interfere with the use of the remaining wireless charging modules.

[0062] As shown in Figure 5 , the bottom of the base 1 is also provided with a suction cup 6 and a storage groove 12 for storing the third wireless charging module 5, and the suction cup 6 covers the storage groove 12. When storing, the third wireless charging module 5 can be stored in the storage groove 12 at the bottom of the base 1, and then the suction cup 6 can be used to cover it, so as to protect the third wireless charging module 5 from being lost.

[0063] The suction cup 6 is arranged at the bottom of the base 1, which is convenient for adsorbing and fixing the base 1 on a placing carrier such as a table top, thereby improving the fixing effect of the wireless charger. Especially when the folding frame 2 is opened and the smart phone is placed on the first wireless charging module 3 for charging and using at the same time, it can effectively prevent the smart phone and the wireless charger from being easily knocked down, and effectively improve the use experience.

[0064] It should be noted that the first wireless charging module 3, the second wireless charging module 4 and the third wireless charging module 5 can be preferably provided with a magnetic attraction function, so that the smart phone, the smart earphone box and the smart wearable device can be automatically magnetically attracted and fixed on the corresponding wireless charging module when they are close to the wireless charging module.

[0065] Compared with the prior art, the wireless charger provided by the embodiment of the present application has a very simple overall structure, and adopts a combination of foldable and detachable structures. The wireless charger comprises a base 1 and a folding frame 2, and the folding frame 2 is provided with a first wireless charging module 3 for charging a smart phone. The base 1 is provided with a second wireless charging module 4 for charging a wireless earphone and a third wireless charging module 5 for charging a smart wearable device, which can simultaneously charge multiple devices and effectively improve the convenience of use.

[0066] The folding frame 2 is movably arranged on the base 1, so that the first wireless charging module 3 can stand up the smart phone when in use, allowing the smart phone to be charged and used at the same time; when stored, the first wireless charging module 3 can be stacked on the base 1, which is beneficial to reducing the occupied space and facilitating storage and storage.

[0067] The third wireless charging module 5 is detachably connected to the electrical connection port 11 on the side of the base 1. On the one hand, it does not interfere with the other two wireless charging modules in the setting position, so that the three wireless charging modules can be used at the same time. On the other hand, the bottom of the base 1 is provided with a storage groove 12, and the suction cup 6 can be covered on the storage groove 12, so that the third wireless charging module 5 can be stored in the base 1 when it is not needed. It can protect the third wireless charging module 5 and prevent it from being lost. Users can selectively use it according to their needs, thereby improving the flexibility of use. In addition, the suction cup 6 provided on the bottom of the base 1 is beneficial to enhancing the stability of the base 1 arranged on the placing carrier such as a desktop, and effectively preventing the base 1 from easily sliding.

[0068] The wireless charger provided by the embodiment of the present application has a compact overall structure, and the folding frame 2 and the detachable and stored third wireless charging module 5 are designed, so that the entire wireless charger is easy to carry, suitable for use in mobile and various application scenarios, and effectively improves the applicability of the wireless charger.

[0069] For the storage structure of the third wireless charging module 5 on the base 1, in an embodiment of the present application, please refer to Figure 6 and Figure 7 The storage groove 12 in the bottom of the base 1 comprises a groove 121 located in the middle and expansion grooves 122 located on both sides of the groove 121 and oppositely arranged. The groove 121 cooperates with the shape of the third wireless charging module 5, and the expansion grooves 122 on both sides of the groove 121 are in communication with the groove 121.

[0070] In the storage, the main body part of the third wireless charging module 5 can be stored in the groove 121, and the electrical connection end of the third wireless charging module 5 can be embedded in the expansion groove 122 on any side, effectively ensuring the fixing effect of the third wireless charging module 5. As an example, as shown in Figure 7 , the electrical connection end of the third wireless charging module 5 is embedded in the expansion groove 122a; the expansion groove 122b on the other side is vacant and can be used as an operation groove, so that the hand can be inserted into the expansion groove 122b on this side, and the third wireless charging module 5 can be conveniently taken out, effectively improving the disassembly convenience of the third wireless charging module 5.

[0071] Preferably, in another embodiment of the present application, please refer to Figure 2 , Figure 3 and Figure 5 , the electrical connection end of the third wireless charging module 5 is preferably a flat end, the electrical connection port 11 on the base 1 is preferably a flat port, and the electrical connection port 11 is matched with the shape of the electrical connection end of the third wireless charging module 5.

[0072] In this way, when the electrical connection end of the third wireless charging module 5 is connected to the electrical connection port 11 on the side of the base 1, the orientation of the third wireless charging module 5 is also set, which is beneficial to the upward orientation of the main body part of the smart wearable device, so that the user can observe the display information on the main body of the smart wearable device during charging, and the use experience is improved.

[0073] In actual application, since the suction cup 6 is covered on the storage groove 12 of the base 1, the detachable structure of the suction cup 6 is particularly important, otherwise it will affect the taking and placing operation of the third wireless charging module 5.

[0074] At this point, for the mounting structure of the suction cup 6, in an embodiment of the present application, please refer to Figure 7 , Figure 8 and Figure 9 , the suction cup 6 is provided with a buckle 61 for screwing operation, and the bottom of the base 1 is provided with a screwing groove 13 for buckling the buckle 61, so that the user can screw the suction cup 6, and the buckle 61 on the suction cup 6 can be screwed into the screwing groove 13 on the bottom of the base 1.

[0075] In the present embodiment, the suction cup 6 is uniformly provided with four buckles 61, and the bottom of the base 1 is provided with four screwing grooves 13 corresponding to the positions of the buckles 61. In actual operation, the four buckles 61 can be inserted into the corresponding screwing grooves 13, and the suction cup 6 can be rotated forward or reversely, so as to realize the mounting locking or unlocking and dismounting of the suction cup 6, and effectively improve the dismounting efficiency of the suction cup 6.

[0076] For the structure on the suction cup 6, in an embodiment of the present application, please refer to Figure 8 and Figure 9 , the suction cup 6 is also provided with an exhaust hole 62, which is arranged through the suction cup 6, thereby ensuring the exhaust function of the suction cup 6.

[0077] When the suction cup 6 is pressed to a smooth surface, the air inside the suction cup 6 needs to be exhausted through the exhaust hole 62, thereby forming a negative pressure, which is conducive to enhancing the suction force of the suction cup 6. The exhaust hole 62 can also avoid the formation of air bubbles by the residual air inside the suction cup 6, ensure the close fit between the suction cup 6 and the contact surface, and further improve the suction stability. In addition, the exhaust hole 62 can also reduce the stress of the suction cup 6 during suction and disassembly, which is conducive to preventing the suction cup 6 from being damaged due to excessive deformation or tearing, thereby prolonging the service life of the suction cup 6.

[0078] For the suction control structure of the suction cup 6, in an embodiment of the present application, please refer to Figure 9 and Figure 10 , the base 1 is also provided with a control assembly for controlling the suction function of the suction cup 6, and the suction cup 6 has an operation hole 63 matched with the control assembly. At least part of the components of the control assembly extends into the suction cup 6 from the operation hole 63, thereby controlling the negative pressure inside the suction cup 6, which is conducive to the suction fixing or disengaging operation of the suction cup 6.

[0079] For the specific structure of the control assembly, including but not limited to the following forms:

[0080] In an embodiment of the present application, please refer to Figure 10 and Figure 11 , the control assembly can include a key 71, an abutting piece 72, and an elastic piece 73. The key 71 is connected with the abutting piece 72, which can be preferably integrally connected. The key 71 can drive the abutting piece 72 to penetrate into the inside of the suction cup 6 from the operation hole 63 of the suction cup 6 under the action of force, and abut on the surface of the carrier such as a desktop to lift the base 1, thereby realizing the disengagement of suction.

[0081] In the present embodiment, the key 71 is exposed from the opening 14 on the upper surface of the base 1 for manual pressing. When the user presses the key 71, the abutting piece 72 penetrates into the inside of the suction cup 6 from the operation hole 63, and abuts on the surface of the carrier such as a desktop to lift the base 1, thereby quickly releasing the negative pressure inside the suction cup 6, and making the suction cup 6 easily separate from the suction surface. Especially in the scene where the wireless charger needs to be frequently moved or disassembled (such as when used in a vehicle), the user can quickly disassemble the wireless charger without having to pull the suction cup 6.

[0082] Among them, such as Figure 10 and Figure 11As shown, the elastic member 73 is arranged between the abutting member 72 and the inner wall of the base 1, and the elastic member 73 can preferably adopt a spring. The spring is sleeved on the abutting member 72, and the two ends of the spring are respectively abutted between the limiting portion of the abutting member 72 and the inner wall of the base 1. When the button 71 is released, the elastic member 73 can automatically reset the abutting member 72 and the button 71, which is convenient for next use, does not need manual operation, realizes the automatic reset function, and improves the use experience.

[0083] In another embodiment of the present application, referring to Figure 12 and Figure 13 , the control assembly can include a micro switch 81 and a micro air pump 82. The micro air pump 82 is arranged on the main control board 10, and the output end of the micro air pump 82 extends into the suction cup 6 from the operation hole 63 of the suction cup 6. The micro air pump 82 can quickly establish or release negative pressure in the suction cup 6, so that the suction cup 6 is quickly adsorbed or separated from the surface, effectively reducing the waiting time.

[0084] In this embodiment, the micro switch 81 is arranged on the micro air pump 82 and exposed from the opening 14 on the outer periphery of the base 1 for manual pressing. The micro switch 81 is used to control the micro air pump 82 to establish or release negative pressure in the suction cup 6. As can be seen, the working state of the micro air pump 82 is controlled by the micro switch 81, and the user only needs to operate the micro switch 81 to realize the adsorption or release of the suction cup 6, effectively improving the use convenience. Especially in the scene where the wireless charger needs to be frequently moved or disassembled (such as vehicle use), the user can quickly complete the operation, improving the use efficiency.

[0085] In this way, the control assembly design using the micro air pump 82 and the micro switch 81 can accurately control the negative pressure in the suction cup 6, which is beneficial to realize the dynamic adjustment of the adsorption force and the quick adsorption or release function. Not only improves the convenience of operation and the stability of adsorption, but also improves the user experience, which is suitable for use in various application scenarios.

[0086] For the structure of the folding frame 2, in one embodiment of the present application, referring to Figure 14 , the folding frame 2 at least includes a folding plate 21, and the two ends of the folding plate 21 are respectively hinged to the base 1 and the first wireless charging module 3.

[0087] The first wireless charging module 3 can be supported by the folding plate 21 above the base 1, which is convenient for placing the smart phone on the first wireless charging module 3 to stand up to charge and use at the same time. When storing, the first wireless charging module 3 can be folded and deformed on the base 1 by the folding plate 21, so as to be stacked on the base 1 and integrated with the base 1, which is convenient for storage.
