Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a wireless charging device. Background Technology

[0002] Wireless charging devices use the principle of electromagnetic induction to charge electronic devices. By configuring a transmitting coil in the wireless charging device and a receiving coil in the electronic device, the transmitting coil emits electromagnetic signals to the outside world under the action of current, and the receiving coil receives the electromagnetic signals and converts them into current, thereby achieving the purpose of wireless charging.

[0003] With the diversification of electronic devices, users often own multiple devices simultaneously (e.g., smartwatches, mobile phones, headphones, etc.), but wireless charging devices cannot meet the charging needs of multiple devices at the same time. Therefore, some wireless charging devices now incorporate multiple wireless charging components, integrating them into the device's casing to wirelessly charge multiple electronic devices simultaneously.

[0004] However, as the number of wireless charging components increases, the space occupied by these components becomes larger, resulting in a larger overall size for wireless charging devices equipped with multiple wireless charging components. Utility Model Content

The second wireless charging component is movably connected to the first housing to be housed in or extend out of the placement groove. The second housing is rotatably connected to the first housing. The second housing has a closed state and an open state relative to the first housing. When the second housing is in the closed state relative to the first housing, the second housing covers the first housing and blocks the placement groove, and the second wireless charging component is housed in the placement groove. When the second housing is in the open state relative to the first housing, the placement groove is open.

[0007] As an optional implementation, in this embodiment of the present invention, the second wireless charging component includes a housing and a second coil. The housing has a rotating end, which is rotatably connected to the first housing. The second coil is disposed inside the housing.

[0008] As an optional implementation, in this embodiment of the present invention, the side wall of the placement groove is provided with an assembly notch, and the rotating end is disposed at the assembly notch.

[0009] As an optional implementation, in this embodiment of the present invention, the second wireless charging component further includes a reset member, which is disposed on the first housing. The reset member acts on the outer shell to provide a force to rotate the outer shell relative to the first housing to a position extending out of the placement slot when the second housing switches from the closed state to the open state relative to the first housing.

[0010] As an optional implementation, in this embodiment of the present invention, the rotating end is rotatably connected to the first housing via a rotating shaft, and the reset element is a torsion spring, which is sleeved on the rotating shaft.

[0011] As an optional implementation, in this embodiment of the present invention, the second charging position is located on the side of the second wireless charging component away from the first housing. When the second wireless charging component extends out of the placement slot, an angle α is formed between the second wireless charging component and the first housing, where 30°≤α≤75°.

[0012] As an optional implementation, in this embodiment of the present invention, the wireless charging device further includes a sub-plate disposed in the receiving cavity. The rotating end of the outer shell is provided with a wire-passing hole, which connects the interior of the outer shell and the receiving cavity. The wires of the second coil extend through the wire-passing hole to the receiving cavity and are electrically connected to the sub-plate. The first wireless charging component includes a first coil disposed in the receiving cavity, and the wires of the first coil are electrically connected to the sub-plate.

[0013] As an optional implementation, in this embodiment of the present invention, the outer shell includes a base portion and a rod portion. One end of the rod portion is connected to the base portion, and the end of the rod portion away from the base portion is the rotating end. The second coil is disposed inside the base portion, and the second charging position is disposed on the side of the base portion away from the first housing. The surface of the rod portion away from the first housing is lower than the surface where the second charging position is located.

[0014] As an optional implementation, in this embodiment of the present invention, the wireless charging device further includes a motherboard and a third wireless charging component. The motherboard is disposed inside the second housing. The first wireless charging component and the second wireless charging component are electrically connected to the motherboard. The third wireless charging component is disposed in the second housing and electrically connected to the motherboard. The third wireless charging component has a third charging position, which is located on the side of the second housing close to the second wireless charging component.

[0015] As an optional implementation, in this embodiment of the present invention, the wireless charging device further includes a sub-board, which is disposed in the receiving cavity and electrically connected to the main board. The first wireless charging component and the second wireless charging component are electrically connected to the sub-board.

[0016] As an optional implementation, in this embodiment of the present invention, the wireless charging device further includes a first magnetic attractor and a second magnetic attractor. The first magnetic attractor is disposed on the first housing, and the second magnetic attractor is disposed on the second housing. When the second housing is in a closed state relative to the first housing, the second magnetic attractor and the first magnetic attractor are magnetically attracted to each other.

[0017] As an optional implementation, the wireless charging device further includes a third wireless charging component, which is disposed on the second housing and has a third charging position located on the side of the second housing close to the second wireless charging component.

[0018] Compared with the prior art, the embodiments of this utility model have at least the following beneficial effects:

[0019] In this embodiment of the invention, the first housing and the second housing are rotatably connected, allowing the first housing and the second housing to rotate relative to each other. The second housing has both a closed state and an open state relative to the first housing. The first housing has a receiving cavity and a placement groove recessed on its surface. A first wireless charging component is disposed in the receiving cavity and corresponding to the placement groove, forming a first charging position on the inner wall of the placement groove. Electronic devices can be placed in the first charging position for wireless charging. The second wireless charging component has a second charging position, allowing electronic devices to be placed in the second charging position for wireless charging. The second wireless charging component is movably connected to the first housing to be housed in or extend out of the placement groove. When using a wireless charging device to charge an electronic device, the first housing and the second housing can rotate relative to each other, allowing the second housing to switch to an open state relative to the first housing. In this case, the placement groove opens to allow the second wireless charging component to extend out of the placement groove, enabling the placement of electronic devices in both the first and second charging positions, thereby charging the electronic devices using both the first and second wireless charging components.

[0020] When charging is not required, the first and second housings can be rotated relative to each other to switch the second housing to a closed state relative to the first housing. At this time, the second housing covers the placement slot and the second wireless charging component is stored in the placement slot, which can reduce the space occupied by the wireless charging component and make the overall size of the wireless charging device smaller.

[0039] This utility model discloses a wireless charging device. The wireless charging components occupy a small space, and the overall size of the wireless charging device is small.

[0040] Please see Figures 1 to 4This is a schematic diagram of the structure of a wireless charging device 100 provided in an embodiment of the present invention. The wireless charging device 100 includes a first housing 10, a first wireless charging component 21, a second wireless charging component 22, and a second housing 30. The first housing 10 has a receiving cavity 10b and a placement groove 10a recessed in its surface. The first wireless charging component 21 is disposed in the receiving cavity 10b and is positioned corresponding to the placement groove 10a to form a first charging position in the placement groove 10a. The second wireless charging component 22 has a second charging position. The second wireless charging component 22 and the first... The housing 10 is movably connected to be housed in or extend out of the placement slot 10a. The second housing 30 is rotatably connected to the first housing 10. The second housing 30 has a closed state and an open state relative to the first housing 10. When the second housing 30 is in the closed state relative to the first housing 10, the second housing 30 covers the first housing 10 and blocks the placement slot 10a, and the second wireless charging component 22 is housed in the placement slot 10a. When the second housing 30 is in the open state relative to the first housing 10, the placement slot 10a opens to allow the second wireless charging component 22 to extend out of the placement slot 10a.

[0041] The first charging position and the second charging position refer to the positions for placing electronic devices. For example, if an electronic device is placed in the first charging position, it can be charged using the first wireless charging component.

[0042] Optionally, the electronic device may include a smartwatch, earphones, a mobile phone, etc. For example, the first charging position is used to place the earphones and charge them using the first wireless charging component 21, and the second charging position is used to place the watch and charge it using the second wireless charging component 22.

[0043] like Figure 1 As shown, the closed state refers to the state in which the first housing 10 and the second housing 30 are stacked on top of each other. Figure 2 As shown, the open state refers to the state in which the first housing 10 and the second housing 30 are tilted, vertical, or horizontal.

[0044] In this embodiment, the first housing 10 and the second housing 30 are rotatably connected, allowing the first housing 10 and the second housing 30 to rotate relative to each other. The second housing 30 has a closed state and an open state relative to the first housing 10. Simultaneously, the first housing 10 has a receiving cavity 10b inside and a placement groove 10a recessed on its surface. The first wireless charging component 21 is disposed in the receiving cavity 10b and corresponding to the placement groove 10a, forming a first charging position within the placement groove 10a. Electronic devices can then be placed in the first charging position for wireless charging. The second wireless charging component 22 has a second charging position, allowing electronic devices to be placed in the first charging position for wireless charging. When the electronic device is placed in the second charging position for wireless charging, and the second wireless charging component 22 is movably connected to the first housing 10 to be housed in or extend out of the placement slot 10a, the electronic device can be charged by rotating the first housing 10 and the second housing 30 relative to each other, so that the second housing 30 is switched to the open state relative to the first housing 10. At this time, the placement slot 10a is opened to allow the second wireless charging component 22 to extend out of the placement slot 10a, so that the electronic device can be placed in the first charging position and the second charging position, thereby using the first wireless charging component 21 and the second wireless charging component 22 to charge the electronic device.

[0045] When charging is not required, the first housing 10 and the second housing 30 can be rotated relative to each other to switch the second housing 30 to a closed state relative to the first housing 10. At this time, the second housing 30 blocks the placement slot 10a, and the second wireless charging group 22 is stored in the placement slot 10a, which can reduce the space occupied by the wireless charging components and make the overall volume of the wireless charging device 100 smaller.

[0046] In some embodiments, when the second housing 30 switches between a closed state and an open state relative to the first housing 10, the second wireless charging component 22 moves relative to the first housing 10 to be housed in or protrude from the placement slot 10a. Thus, by linking the state switching of the second housing 30 relative to the first housing 10 with the movement of the second wireless charging component 22 relative to the first housing 10, when the second housing 30 switches from a closed state to an open state relative to the first housing 10, the second wireless charging component 22 moves relative to the first housing 10, switching from being housed in the placement slot 10a to protruding from the placement slot 10a. At this time, the electronic device can be placed in the first charging position and the second charging position for charging. Conversely, when the second housing 30 switches from an open state to a closed state relative to the first housing 10, the second wireless charging component 22 moves relative to the first housing 10, switching from protruding from the placement slot 10a to being housed in the placement slot 10a. At this time, the wireless charging device 100 can be housed. This improves the efficiency of the wireless charging device 100 switching between charging and not charging, resulting in a high degree of automation.

[0047] In some other embodiments, the second wireless charging component 22 may also be movably disposed on the first housing 10 by means of sliding, telescopic or other means, which can be selected according to the actual situation. This embodiment does not make specific limitations on this.

[0048] In some embodiments, such as Figure 5 and Figure 6 As shown, the second wireless charging component 22 includes a housing 221 and a second coil 222. The housing 221 has a rotating end 221a, which is rotatably connected to the first housing 10. The second coil 222 is disposed inside the housing 221. Thus, by rotating the housing 221 to the first housing 10, the second wireless charging component 22 can rotate relative to the first housing 10. Furthermore, by providing the second coil 222 inside the housing 221, an electronic device placed in the second charging position of the housing 221 can receive the electromagnetic signal emitted by the second coil 222 and convert the electromagnetic signal into current, thereby achieving wireless charging.

[0049] For example, the outer casing 221 has a free end 221b opposite to the rotating end 221a. The free end 221b is disposed away from the rotation axis 224 between the first casing 10 and the second casing 30 relative to the rotating end 221a. When the second casing 30 switches from an open state to a closed state relative to the first casing 10, the second casing 30 abuts against the outer casing 221 to push the outer casing 221 to rotate relative to the first casing 10 and be housed in the placement groove 10a. In this way, by displacing the free end 221b away from the rotation axis 224 between the first casing 10 and the second casing 30 relative to the rotating end 221a, when the second casing 30 switches from an open state to a closed state relative to the first casing 10, the second casing 30 can abut against the outer casing 221 to push the outer casing 221 to rotate relative to the first casing 10 and be housed in the placement groove 10a.

[0050] In some embodiments, the side wall of the placement slot 10a is provided with an assembly notch 10c, and the rotating end 221a is disposed in the assembly notch 10c. In this way, by accommodating the rotating end 221a through the assembly notch 10c, when the rotating end 221a rotates relative to the first housing 10 until the second wireless charging component 22 extends out of the placement slot 10a, the housing 221 can avoid occupying the space of the placement slot 10a, so that the first charging position can be used to place electronic devices for charging.

[0051] For example, such as Figure 7As shown, the second wireless charging assembly 22 also includes a reset member 223. The reset member 223 is disposed in the first housing 10 and acts on the outer shell 221 to provide a force when the second housing 30 switches from a closed state to an open state relative to the first housing 10, causing the outer shell 221 to rotate relative to the first housing 10 to a position extending out of the placement slot 10a. In this way, by providing the reset member 223 in the first housing 10, when the second housing 30 switches from a closed state to an open state relative to the first housing 10, the reset member 223 can provide a force to cause the outer shell 221 to rotate relative to the first housing 10 to extend out of the placement slot 10a, thereby realizing the automatic rotation of the outer shell 221.

[0052] Optionally, the rotating end 221a is rotatably connected to the first housing 10 via a rotating shaft 224, and the reset member 223 is a torsion spring sleeved on the rotating shaft 224. In this way, the rotating end 221a is rotatably connected to the first housing 10 via the rotating shaft 224, thereby enabling the outer shell 221 to rotate relative to the first housing 10. Furthermore, by utilizing the torsion spring sleeved on the rotating shaft 224 and the elastic force provided by the torsion spring, the outer shell 221 rotates relative to the first housing 10 until it extends out of the placement slot 10a, achieving automatic rotation of the outer shell 221. This eliminates the need for additional driving components such as motors, simplifying the overall structure of the wireless charging device 100.

[0053] For example, such as Figure 8As shown, the second charging position is located on the side of the second wireless charging component 22 facing away from the first housing 10. When the second wireless charging component 22 extends out of the placement slot 10a, an angle α is formed between the second wireless charging component 22 and the first housing 10, where 30°≤α≤75°. If the angle α between the second wireless charging component 22 and the first housing 10 is less than 30°, the angle α is relatively small, and the distance between the second wireless charging component 22 and the placement slot 10a is relatively close, which may easily obstruct the placement slot 10a and affect the electronic device from being placed in the placement slot 10a for charging. Furthermore, it is difficult for the user to view the time, information, and other content displayed on the electronic device. If the angle α between the second wireless charging component 22 and the first housing 10 is greater than 75°, the angle α is relatively large, and the electronic device placed on the second wireless charging component 22 is easily detached from the second wireless charging component 22 due to gravity, causing charging interruption. It is also difficult for the user to view the time, information, and other content displayed on the electronic device. Therefore, the included angle α between the second wireless charging component 22 and the first housing 10 can be 30°≤α≤75°. The second wireless charging component 22 is far away from the placement slot 10a, which can avoid obstructing the placement slot 10a and affecting the electronic device being placed in the placement slot 10a for charging. At the same time, it can prevent the electronic device placed on the second wireless charging component 22 from being easily detached from the second wireless charging component 22 due to gravity, which would cause the charging to be interrupted. It can also make it convenient for users to view the time, information and other content displayed on the electronic device.

[0054] Furthermore, the included angle α between the second wireless charging component 22 and the first housing 10 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc., and this embodiment does not make a specific limitation on this.

[0055] In some embodiments, such as Figure 5 and Figure 8As shown, the wireless charging device 100 also includes a sub-board 40, which is disposed in the receiving cavity 10b. The rotating end 221a of the outer shell 221 is provided with a wire-passing hole 221c, which connects the interior of the outer shell 221 and the receiving cavity 10b. The wiring of the second coil 222 extends to the receiving cavity 10b through the wire-passing hole 221c and is electrically connected to the sub-board 40. The first wireless charging component 21 includes a first coil, which is disposed in the receiving cavity 10b, and its wiring is electrically connected to the sub-board 40. In this way, on the one hand, by setting the sub-board 40 in the receiving cavity 10b and using the wire-passing hole 221c for wiring, the wiring of the second coil 222 can extend to the receiving cavity 10b and be electrically connected to the sub-board 40. On the other hand, by using the sub-board 40 to be electrically connected to the first coil, the second wireless charging component 22 and the first wireless charging component 21 can be controlled by the sub-board 40, which can reduce the number of circuit boards and simplify the structure of the wireless charging device 100.

[0056] For example, such as Figure 5 and Figure 6 As shown, the outer casing 221 includes a base portion 2211 and a rod portion 2212. One end of the rod portion 2212 is connected to the base portion 2211. The end of the rod portion 2212 away from the base portion 2211 is a rotating end 221a. The second coil 222 is disposed inside the base portion 2211. The second charging position is disposed on the side of the base portion 2211 away from the first housing 10. The surface of the rod portion 2212 away from the first housing 10 is lower than the surface where the second charging position is located. A wire hole 221c is disposed in the rod portion 2212 and extends from the rotating end 221a into the interior of the base portion 2211. In this way, the second coil 222 is set through the base part 2211, and the rotating end 221a of the wire hole 221c passes through to the inside of the base part 2211, so that the wire of the second coil 222 can extend to the receiving cavity 10b through the wire hole 221c to achieve electrical connection with the sub-plate 40. The side surface of the rod part 2212 facing away from the first housing 10 is lower than the surface where the second charging position is located, which can play a role in making way and preventing the electronic device from easily abutting against the surface of the rod part 2212 when it is placed on the second charging position, so that the electronic device cannot fit well on the second charging position for charging.

[0057] Among them, the end of the seat part 2211 that is away from the rod part 2212 is the free end 221b.

[0058] In some embodiments, such as Figure 8As shown, the wireless charging device 100 also includes a motherboard 50, which is located inside the second housing 30. The first wireless charging component 21 and the second wireless charging component 22 are electrically connected to the motherboard 50. Thus, by placing the motherboard 50 inside the second housing 30, the first wireless charging component 21 and the second wireless charging component 22 are electrically connected to the motherboard 50, thereby enabling control of the first wireless charging component 21 and the second wireless charging component 22. Furthermore, since the first wireless charging component 21 and the second wireless charging component 22 are located in the first housing 10, and in a different housing from the motherboard 50, the space of the first housing 10 and the second housing 30 can be fully utilized, resulting in a smaller overall size of the wireless charging device 100.

[0059] For example, the sub-board 40 is electrically connected to the main board 50, and the wireless charging component 20 disposed in the first housing 10 is electrically connected to the sub-board 40. By using the sub-board 40 to electrically connect with the first wireless charging component 21 and the second wireless charging component 22, and by electrically connecting the main board 50 to the sub-board 40, the electrical connection lines between the first wireless charging component 21, the second wireless charging component 22 and the main board 50 are integrated, thereby simplifying the wiring.

[0060] In some embodiments, such as Figure 4 and Figure 9 As shown, the wireless charging device 100 also includes a connector 60 and an electrical connector (not shown). The connector 60 is rotatably connected to the first housing 10 and the second housing 30. The connector 60 has a first through hole 60a, which communicates with the interior of the receiving cavity 10b and the second housing 30. The electrical connector passes through the first through hole 60a, with one end extending into the receiving cavity 10b and electrically connected to the sub-plate 40, and the other end extending into the interior of the second housing 30 and electrically connected to the main board 50. In this way, the rotatable connection between the connector 60 and the first housing 10 and the second housing 30 allows the first housing 10 and the second housing 30 to rotate relative to the connector 60, thereby switching between a closed state and an open state. On the other hand, by providing a first through hole 60a in the connector 60, and passing an electrical connector through the first through hole 60a, the two ends of the electrical connector extend into the cavity 10b and the interior of the second housing 30 respectively, and are electrically connected to the sub-board 40 and the main board 50 respectively, thereby realizing the electrical connection between the main board 50 and the wireless charging component 20 provided in the first housing 10.

[0061] For example, such as Figure 9 and Figure 10As shown, the wireless charging device 100 also includes a protective member 70, which passes through a first through hole 60a and has a second through hole 70a. The second through hole 70a connects to the interior of the receiving cavity 10b and the second housing 30. An electrical connector passes through the second through hole 70a. The hardness of the protective member 70 is less than that of the connector 60. Thus, by having the protective member 70 pass through the first through hole 60a and by utilizing the second through hole 70a of the protective member 70 to connect with the interior of the receiving cavity 10b and the second housing 30, the electrical connector can pass through the second through hole 70a, thereby extending into the interior of the receiving cavity 10b and the second housing 30. On the other hand, since the hardness of the protective component 70 is less than that of the connecting component 60, the connecting component 60 has a higher hardness. When the first housing 10 and the second housing 30 rotate relative to the connecting component 60, the connecting component 60 can withstand greater stress. This ensures that the second housing 30 does not fail to rotate relative to the first housing 10 after multiple switching between closed and open states, thus extending the service life of the wireless charging device 100. The lower hardness of the protective component 70 prevents wear on the electrical connectors, which could affect their service life.

[0062] In some embodiments, such as Figure 4 As shown, the wireless charging device 100 also includes a third wireless charging component 23, which is disposed in the second housing 30. Thus, by disposing of the third wireless charging component 23 in the second housing 30, the first wireless charging component 21, the second wireless charging component 22, and the third wireless charging component 23 are distributed across the first housing 10 and the second housing 30, making full use of the space in the first housing 10 and the second housing 30, resulting in a smaller overall size of the wireless charging device 100.

[0063] Optionally, the third wireless charging component 23 is provided with a third charging position, which can be used to place electronic devices such as mobile phones for wireless charging using the third wireless charging component 23. Preferably, the third charging position is located on the side of the second housing 30 near the second wireless charging component 22. That is, when the second housing 30 is closed relative to the first housing 10, the charging surface of the third charging position faces the second wireless charging component 22. This design ensures that when the second housing 30 is open relative to the first housing 10, the charging surfaces of the first wireless charging component 21 and the third wireless charging component 23 are both facing upwards, making it convenient to use the first wireless charging component 21, the second wireless charging component 22, and the third wireless charging component 23 to charge three devices simultaneously.

[0064] For example, such as Figure 4As shown, the wireless charging device 100 also includes a first magnetic member 81 and a second magnetic member 82. The first magnetic member 81 is disposed on the first housing 10, and the second magnetic member 82 is disposed on the second housing 30. When the second housing 30 is in a closed state relative to the first housing 10, the second magnetic member 82 magnetically engages with the first magnetic member 81. Thus, by respectively providing the first magnetic member 81 and the second magnetic member 82 on the first housing 10 and the second housing 30, when the second housing 30 is switched to a closed state relative to the first housing 10, the second magnetic member 82 can magnetically engage with the first magnetic member 81, thereby keeping the first housing 10 and the second housing 30 in a closed state.

[0065] Optionally, the first magnetic attractor 81 and the second magnetic attractor 82 can be magnets, electromagnets, etc., and can be selected according to the actual situation. This embodiment does not make specific limitations on this.

[0066] This utility model provides a wireless charging device 100. A first housing 10 and a second housing 30 are rotatably connected, allowing the first housing 10 and the second housing 30 to rotate relative to each other. The second housing 30 has both a closed and an open state relative to the first housing 10. The first housing 10 has a receiving cavity 10b and a placement groove 10a recessed on its surface. A first wireless charging component 21 is disposed in the receiving cavity 10b and corresponding to the placement groove 10a, forming a first charging position on the inner wall of the placement groove 10a. Electronic devices can be placed in the first charging position for wireless charging. The second wireless charging component 22 has a second charging position. In the second charging position, the electronic device can also be placed in the second charging position for wireless charging. The second wireless charging component 22 is movably connected to the first housing 10 to be housed in or extend out of the placement slot 10a. When the wireless charging device 100 is used to charge the electronic device, the first housing 10 and the second housing 30 can be rotated relative to each other to switch the second housing 30 to the open state relative to the first housing 10. At this time, the placement slot 10a is opened to allow the second wireless charging component 22 to extend out of the placement slot 10a, so that the electronic device can be placed in the first charging position and the second charging position, thereby using the first wireless charging component 21 and the second wireless charging component 22 to charge the electronic device.

[0067] When charging is not required, the first housing 10 and the second housing 30 can be rotated relative to each other to switch the second housing 30 to a closed state relative to the first housing 10. At this time, the second housing 30 blocks the placement slot 10a, and the second wireless charging group 22 is stored in the placement slot 10a, which can reduce the space occupied by the wireless charging components and make the overall volume of the wireless charging device 100 smaller.
