Detailed Description
The terminology used in the description of the embodiments of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the application, as the embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Wireless charging technology (Wireless charging technology) is derived from Wireless power transmission technology, and can be divided into two modes of low-power Wireless charging and high-power Wireless charging. The wireless charging technology is generally classified into an electromagnetic induction type, a magnetic field resonance type, and a radio wave type.
In the electromagnetic induction type, alternating current with a certain frequency of a primary coil generates a certain current in a secondary coil through electromagnetic induction, so that energy is transferred from a transmission end to a receiving end. The most common charging solution at present uses electromagnetic induction. In the case of magnetic resonance, the energy transmission device and the energy reception device are configured such that they can exchange energy with each other when they are tuned to the same frequency, or resonate at a specific frequency. In the radio wave type, the microwave energy collecting device mainly comprises a microwave transmitting device and a microwave receiving device, can capture the radio wave energy rebounded from a wall, and keeps stable direct current voltage while adjusting with the load. This approach requires only a single transmitter mounted on the wall plug and a "mosquito" receiver that can be mounted on any low voltage product.
The low-power wireless charging is usually performed in an electromagnetic induction manner, such as a charging manner for a mobile phone, and some wireless charging manners are performed in an induction manner. High power wireless charging often uses magnetic field resonance (which is the way most electric vehicles charge) to transfer energy from a power supply device (e.g., a charger) to a powered device that uses the received energy to charge a battery and also to operate itself. Because the charger and the electric device transmit energy by magnetic field, the charger and the electric device are not connected by electric wires, so that no conductive contact is exposed.
With the continuous development of communication technology, the electromagnetic induction principle has been gradually applied to the field of wireless charging. In the prior art, a wireless charging device utilizes an electromagnetic energy conversion principle, a transmitting coil is arranged at a charging terminal, a receiving coil is arranged at a charging terminal, and the receiving coil generates current according to an electromagnetic induction principle and charges the terminal. However, the conventional wireless charging device can only charge one charging terminal at a time, cannot simultaneously charge a plurality of charging terminals, and is low in efficiency.
Based on this, the embodiment of the application provides a wireless charging device, the wireless charging device drives at least one connecting rod assembly to rotate around a fixed shaft through a first driving assembly, and an induction coil is wound on each connecting rod assembly, when a certain device to be charged needs to be charged, at least one connecting rod component drives an induction coil wound on the connecting rod component to rotate around the fixed shaft relatively, so that the induction coil rotates and identifies the specific position of the device to be charged to charge the device, the device to be charged can be automatically searched and charged, and the situation that only one device to be charged at a certain fixed position can be charged in the prior art is avoided, if the position of the device to be charged moves, the position of the wireless charging device needs to be manually adjusted, so that the charging efficiency of the equipment to be charged is improved to a great extent.
The following describes a specific structure of the wireless charging device in detail with reference to different embodiments as examples, with reference to the accompanying drawings.
Example one
Referring to fig. 1 to fig. 3, an embodiment of the present application provides a wireless charging apparatus 100, where the wireless charging apparatus 100 is configured to wirelessly charge a device to be charged, where the wireless charging apparatus 100 at least includes: a first driving assembly 10, a linkage assembly 20 and at least one induction coil 30.
It should be noted that, in this embodiment of the application, the device to be charged may be a mobile or fixed terminal that needs to be charged, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, an intercom, a netbook, a Point of sale (POS) machine, a Personal Digital Assistant (PDA), a wearable device, a virtual reality device, a wireless usb disk, a bluetooth sound/earphone, or a vehicle-mounted front-end device, a car recorder, a security device, and the like.
Specifically, in the embodiment of the present application, the linkage assembly 20 may include: the first driving assembly 10 drives the connecting rod assembly 202 to rotate relatively around the fixed shaft 201, and the induction coil 30 is wound at one end of the connecting rod assembly 202 far away from the fixed shaft 201.
In the embodiment of the present application, the wireless charging device 100 further includes: and a control component (not shown in the figures), which is electrically connected to the first driving component 10, such that when it is detected that the device to be charged is close to the wireless charging device 100, the control component controls the first driving component 10 to operate, and the first driving component 10 operates to drive the at least one connecting rod assembly 202 to simultaneously rotate 360 degrees around the fixed shaft 201.
In one possible implementation manner, the fixing shaft 201 may be sleeved on at least a portion of an outer wall of the first driving assembly 10.
In order to realize the detection of the device to be charged, the wireless charging device 100 is connected to a circuit board (not shown in the figure) through an electrical connection line, and specifically, the first driving assembly 10 in the wireless charging device 100 is electrically connected to the circuit board through the electrical connection line. In some embodiments, the circuit board may be disposed proximate to a housing for placing the device to be charged, for example, when the housing is a dining table, the device to be charged is generally placed on an upper surface of the dining table top, and the circuit board may be disposed to be attached to a lower surface of the dining table top. It should be noted that the housing will not be described here, but will be described in detail in the following specific embodiments.
Specifically, a plurality of shunt selection chips and a plurality of small coils electrically connected with the shunt selection chips are arranged on the circuit board, each small coil corresponds to different position coordinates on the shell, in an actual working state, the small coils are electrified to work and send request signals, if the equipment to be charged needs to be wirelessly charged, the equipment to be charged is placed on the shell, the coil arranged inside the equipment to be charged can receive the request signals transmitted by the small coil corresponding to the position coordinate closest to the coil and reply response signals to the small coil, which is equivalent to the successful initial handshake between the wireless charging device 100 and the equipment to be charged, then the shunt selection chip can lock the position coordinates of the corresponding small coil, and then the corresponding small coil starts to work to find the position. After the position is determined, the control component controls the first driving component 10 to operate, the first driving component 10 drives the link assembly 202 to drive the induction coil 30 wound thereon to move to a corresponding position (i.e., a position corresponding to the device to be charged), and after the position of the induction coil 30 on the link assembly 202 is aligned with the position of the coil inside the device to be charged, the wireless charging device 100 starts to wirelessly charge the device to be charged.
It is understood that the position of the induction coil 30 is aligned with the position of the coil inside the device to be charged, and the orthographic projection of the induction coil 30 on the housing may at least partially overlap with the orthographic projection of the coil inside the device to be charged on the housing, that is, the orthographic projection of the induction coil 30 on the housing may completely overlap with the orthographic projection of the coil inside the device to be charged on the housing, or the orthographic projection of the induction coil 30 on the housing may partially overlap with the orthographic projection of the coil inside the device to be charged on the housing.
Alternatively, in some other embodiments, the orthographic projection of the induction coil 30 on the housing and the orthographic projection of the coil inside the device to be charged on the housing may not overlap, as long as the induction coil 30 and the coil inside the device to be charged can realize mutual induction, and the wireless charging function is ensured.
In the embodiment of the present application, the number of the induction coils 30 may be at least two, the number of the link assemblies 202 is at least two, and at least one induction coil 30 may be wound around an end of each link assembly 202 away from the fixed shaft 201. In this way, the first driving assembly 10 drives the at least two connecting rod assemblies 202 to rotate around the fixed shaft 201, and each connecting rod assembly 202 is wound with the induction coil 30, so that when two or more devices to be charged need to be charged, the induction coils 30 on the at least two connecting rod assemblies 202 can simultaneously charge the at least two devices to be charged, and the charging efficiency is improved to a great extent.
Specifically, when only one device to be charged needs to be charged, one of the at least two link assemblies 202 drives the induction coil 30 wound thereon to move to the corresponding position to wirelessly charge the device to be charged. Taking the wireless charging apparatus 100 shown in fig. 2 as an example, when only one device to be charged needs to be charged, the first link assembly 210 may drive the induction coil 30 wound thereon to move to a corresponding position to wirelessly charge the device to be charged, or the second link assembly 220 may drive the induction coil 30 wound thereon to move to a corresponding position to wirelessly charge the device to be charged.
Taking the wireless charging apparatus 100 shown in fig. 3 as an example, when only one device to be charged needs to be charged, the first link assembly 210 may drive the induction coil 30 wound thereon to move to a corresponding position to wirelessly charge the device to be charged, the second link assembly 220 may drive the induction coil 30 wound thereon to move to a corresponding position to wirelessly charge the device to be charged, or the third link assembly 230 may drive the induction coil 30 wound thereon to move to a corresponding position to wirelessly charge the device to be charged.
When a plurality of devices to be charged need to be charged, the plurality of link assemblies 202 can rotate around the fixing shaft 201 at the same time, so as to drive the induction coil 30 wound thereon to move to a corresponding position, and wirelessly charge the plurality of devices to be charged located at fixed positions.
As an alternative embodiment, the first drive assembly 10 in the present embodiment may be a motor. The motor is an electric motor, and the working principle of the motor is that a starter rotor is driven to rotate by the forced rotation of an electrified coil in a magnetic field, and a pinion on the rotor drives a motor flywheel to rotate.
For example, in some embodiments, a first gear may be coupled to first drive assembly 10. One end of the connecting rod assembly 202 near the first gear may be correspondingly provided with a second gear, and the second gear may be meshed with the first gear of the first driving assembly 10 to cooperatively realize the relative rotation of the connecting rod assembly 202. Specifically, the first driving assembly 10 rotates to drive the first gear to rotate, and the first gear rotates to drive the second gear engaged with the first gear to rotate, so as to drive the connecting rod assembly 202 fixed to the second gear to rotate, and the connecting rod assembly 202 rotates around the fixed shaft 201.
Of course, the first driving assembly 10 may also be other components having driving functions, which are not limited by the embodiments of the present application, and are not limited to the above examples.
It should be noted that, in the embodiment of the present application, the number of the connecting rod assemblies 202 may be two, three, or more, and the embodiment of the present application does not limit this. For example, in fig. 3, the number of the link assemblies 202 of the wireless charging apparatus 100 is two, and the wireless charging apparatus 100 can simultaneously charge two devices to be charged. Alternatively, in fig. 4, the number of the link assemblies 202 of the wireless charging apparatus 100 is three, and the wireless charging apparatus 100 can simultaneously charge three devices to be charged.
It is understood that, in the present embodiment, each connecting rod assembly 202 may include: one link 2021, two links 2021, or more than three links 2021.
For example, as shown in FIG. 1, each linkage assembly 202 may include: a connecting rod 2021, wherein one end of the connecting rod 2021 is rotatably connected to the fixed shaft 201, and the other end of the connecting rod 2021 is wound with an induction coil 30.
Alternatively, as shown in fig. 2 or 3, each link assembly 202 may include: at least two links 2021, each link 2021 may extend along a length of the linkage assembly 202. Moreover, the two adjacent connecting rods 2021 can move relatively along the length direction of the connecting rod assembly 202. By including at least two connecting rods 2021 in each connecting rod assembly 202, and by providing relative movement between two adjacent connecting rods 2021 along the length direction of the connecting rod assembly 202, the total length of the connecting rod assembly 202 can be increased, so that the connecting rod assembly 202 can achieve a telescopic function, and the wireless charging device 100 can be adapted to the housing 200 (see fig. 9) of the wireless charging apparatus 300 with different models.
In one possible implementation manner, the connecting rod 2021 of the at least two connecting rods 2021 close to the fixed shaft 201 is rotatably connected to the fixed shaft 201, and the induction coil 30 is wound on the connecting rod 2021 of the at least two connecting rods 2021 far from the fixed shaft 201.
When the wireless charging device 100 is located at a fixed position, the connecting rod assembly 202 can effectively charge the devices to be charged, which have different distances from the wireless charging device 100, so that the charging efficiency is further improved.
Specifically, as shown in fig. 4, the at least two links 2021 may include: the first link 2022 and the second link 2023, the first link 2022 and the second link 2023 can move relatively along the length direction of the link assembly 202, the first link 2022 is rotatably connected to the fixed shaft 201, and the induction coil 30 is wound around an end of the second link 2023 away from the first link 2022.
By including two links 2021 in each link assembly 202, and by providing relative movement between the two links 2021 along the length direction of the link assembly 202, the length of the overall link assembly 202 can be increased, so that the link assembly 202 can achieve a telescopic function, and the wireless charging device 100 can be adapted to the housings 200 (shown in fig. 9) of the wireless charging apparatuses 300 with different models.
When the wireless charging device 100 is located at a fixed position, the link assembly 202 having the two links 2021 can respectively and effectively charge a plurality of devices to be charged having different distances from the wireless charging device 100, thereby further improving the charging efficiency.
As an alternative embodiment, as shown with reference to fig. 5, each connecting rod assembly 202 may further include: at least one second drive assembly 2024, wherein the second drive assembly 2024 drives one of the two adjacent links 2021 toward or away from the other of the two adjacent links 2021 along the length of the linkage assembly 202. The second driving assembly 2024 drives the two adjacent connecting rods 2021 in the connecting rod assembly 202 to move relatively, so that the telescopic function of the connecting rod assembly 202 can be realized, and the wireless charging device 100 in the embodiment of the present application is adapted to more charging application scenarios.
Here, taking each link assembly 202 including two links 2021 (a first link 2022 and a second link 2023) as an example, the second driving assembly 2024 drives one of the first link 2022 and the second link 2023 to approach or separate from the other of the first link 2022 and the second link 2023 along the length direction of the link assembly 202.
Specifically, when the first link 2022 is relatively close to the fixed shaft 201 and the second link 2023 is relatively far from the fixed shaft 201 (see fig. 5), the second driving assembly 2024 drives the second link 2023 to be close to or far from the first link 2022 along the length direction of the link assembly 202. When the first link 2022 is relatively far away from the fixed shaft 201 and the second link 2023 is relatively close to the fixed shaft 201 (not shown in the figures), the second driving assembly 2024 drives the first link 2022 to be close to or far away from the second link 2023 along the length direction of the link assembly 202. The second driving assembly 2024 drives the relative movement between the first link 2022 and the second link 2023 in the link assembly 202, so as to achieve the telescopic function of the link assembly 202, thereby adapting the wireless charging device 100 to more charging application scenarios.
In this way, by controlling the second driving assembly 2024 to work in a forward direction or a reverse direction, the link assembly 202 can be controlled to extend or contract, so that the induction coil 30 in the wireless charging apparatus 100 can be moved to different positions, and the wireless charging apparatus 300 can be better adapted to different models.
Specifically, the second drive assembly 2024 may be a motor. For example, the second drive assembly 2024 may be a linear motor. Of course, the second driving assembly 2024 may also be other components having driving functions, which are not limited in the embodiments of the present application, and are not limited to the above examples.
In addition, it is easily understood that the connection between the first link 2022 and the second link 2023 includes, but is not limited to, the following two possible implementations:
one possible implementation is: the first connecting rod 2022 is provided with a screw inside one end close to the second connecting rod 2023, the second connecting rod 2023 is provided with a through hole inside one end close to the first connecting rod 2022, and the screw is inserted into the through hole to realize the relative approach or relative separation between the first connecting rod 2022 and the second connecting rod 2023. For example, the larger the overlap dimension between the outer wall of the screw and the inner wall of the through hole in the extending direction of the screw, the closer the second link 2023 is to the first link 2022. The smaller the overlap dimension between the outer wall of the screw and the inner wall of the through hole in the extending direction of the screw, the further away the second link 2023 is from the first link 2022.
The second driving element 2024 may be disposed inside the first connecting rod 2022 and fixedly connected to the screw, such that when the second driving element 2024 (e.g., a motor) rotates to drive the screw to rotate, the second connecting rod 2023 moves along the length direction of the connecting rod assembly 202 to move relatively close to or away from the first connecting rod 2022.
It is understood that the second link 2023 may be located inside the first link 2022 in the telescopic state, so that the shape of the second link 2023 can be utilized to prevent the second link 2023 from rotating relative to the first link 2022.
Another possible implementation is: the first link 2022 and the second link 2023 are slidably connected to each other, the second driving assembly 2024 may be a linear motor, and the second driving assembly 2024 drives the second link 2023 to move along the length direction of the link assembly 202 at a corresponding position, so as to relatively move closer to or away from the first link 2022.
It should be noted that, when the connecting rod assembly 202 includes three or more connecting rods 2021, the above-mentioned connecting method is also applicable, and the description of the embodiments of the present application is omitted.
Additionally, in the subject embodiment, the length of each of the at least two linkage assemblies 202 may not be equal. In this way, when the connecting lines between the at least two devices to be charged and the fixing shaft 201 of the wireless charging device 100 are located at different positions on the same straight line, effective charging of the at least two devices to be charged can be achieved at the same time. It is easy to understand that, if the lengths of at least two link assemblies 202 in at least two link assemblies 202 are equal, when the at least two link assemblies 202 are located on the same straight line, the induction coils 30 wound around the at least two link assemblies 202 overlap with each other, i.e. the at least two induction coils 30 can only charge the device to be charged on the same position, which is inefficient.
Taking the wireless charging device 100 shown in fig. 2 as an example, the number of the connecting rod assemblies 202 in the wireless charging device 100 is two, and the axial lengths of the two connecting rod assemblies 202 are not equal, so that when connecting lines between two devices to be charged and the fixed shaft 201 of the wireless charging device 100 are located at two different positions on the same straight line, the two devices to be charged can be effectively charged at the same time.
It is easy to understand that, if the lengths of the two link assemblies 202 are equal, when the two link assemblies 202 are located on the same straight line, the induction coils 30 wound around the two link assemblies 202 overlap with each other, i.e. the two induction coils 30 can only charge the device to be charged at the same position, which is inefficient.
Taking the wireless charging device 100 shown in fig. 3 as an example, the number of the connecting rod assemblies 202 in the wireless charging device 100 is three, and the axial lengths of the three connecting rod assemblies 202 are not equal, so that when connecting lines between the three devices to be charged and the fixed shaft 201 of the wireless charging device 100 are located at three different positions on the same straight line, the three devices to be charged can be effectively charged at the same time.
It is easy to understand that, if the lengths of the three link assemblies 202 are equal, when the three link assemblies 202 are located on the same straight line, the induction coils 30 wound around the three link assemblies 202 overlap with each other, i.e. the three induction coils 30 can only charge the device to be charged at the same position, which is inefficient.
Alternatively, if two of the three link assemblies 202 have the same length, when the three link assemblies 202 are located on the same straight line, the induction coils 30 wound around the two link assemblies 202 overlap with each other, that is, the three induction coils 30 can only charge the devices to be charged at two different positions, and the efficiency is still low.
Furthermore, in the embodiment of the present application, the wireless charging device 100 may further include: and a power supply assembly (not shown) electrically connected to the induction coil 30 for supplying power to the induction coil 30.
Further, the wireless charging apparatus 100 may further include: and an electrical connector 40, wherein one end of the electrical connector 40 is electrically connected with the induction coil 30, and the other end of the electrical connector 40 is electrically connected with the power supply assembly. The electrical connector 40 is used to make an electrical connection between the power supply assembly and the induction coil 30 so that the power supply assembly provides power to the induction coil 30.
In some embodiments, the electrical connector 40 may be disposed within the interior of the linkage assembly 202, for example, the electrical connector 40 may be threaded within the linkage assembly 202.
In some embodiments, one end of the electrical connector 40 is electrically connected to the induction coil 30 and the other end of the electrical connector 40 extends from the stationary shaft 201 and is connected to a power supply assembly.
Wherein, as an alternative embodiment, the electrical connector 40 may be a power cord.
In the embodiment of the present application, the link 2021 may be any one of a screw, a rack, or a linear motor. The screw rod can convert rotary motion into linear motion, or convert the linear motion into rotary motion, or convert torque into axial repeated acting force, has the characteristics of high precision, reversibility and high efficiency, and has very small frictional resistance.
Example two
Unlike the above-mentioned embodiments, in the present embodiment, the link assemblies 202 in the wireless charging device 100 can rotate around the fixed shaft 201 respectively, that is, taking the wireless charging device 100 having two link assemblies 202 (i.e. the first link assembly 210 and the second link assembly 220) as an example, the second link assembly 220 may be kept stationary, only the first link assembly 210 rotates around the fixed shaft 201, or the first link assembly 210 may be kept stationary, and only the second link assembly 220 rotates around the fixed shaft 201.
Taking the example of the wireless charging device 100 having three link assemblies 202 (i.e., the first link assembly 210, the second link assembly 220, and the third link assembly 230), the second link assembly 220 and the third link assembly 230 may be kept stationary, and only the first link assembly 210 rotates about the fixed shaft 201, or the third link assembly 230 may be kept stationary, and only the first link assembly 210 and the second link assembly 220 rotate about the fixed shaft 201, or alternatively, the first link assembly 210 may be kept stationary and only the second link assembly 220 and the third link assembly 230 rotate about the fixed shaft 201.
It is understood that the present embodiment does not limit the specific rotation of the plurality of link assemblies 202 in the wireless charging device 100 when rotating around the fixed shaft 201, and is not limited to the above example.
Specifically, for example, the wireless charging device 100 has two link assemblies 202 (i.e., a first link assembly 210 and a second link assembly 220), as shown in fig. 6 to 8, the first driving assembly 10 may include: the body 101 and the axis of rotation 102 that links to each other with body 101, the one end that axis of rotation 102 deviates from body 101 is connected with first gear 103, and the one end that each link assembly 202 is close to axis of rotation 102 is connected with second gear 60.
For example, as shown in fig. 6 or 7, the second gear 60 is connected to each of the first link assembly 210 and the second link assembly 220 at one end close to the rotating shaft 102.
In a possible implementation manner, the wireless charging apparatus 100 further includes: a stationary stage 50, wherein the stationary stage 50 comprises: at least two platforms 501 and at least one support 502, at least two platforms 501 are all located at different horizontal planes, and the support 502 is used for supporting and fixing at least two platforms 501. The link assembly 202 is located between two immediately adjacent platforms 501, for example, in fig. 6, the fixed table 50 includes three platforms 501 and three supports 502, wherein the first link assembly 210 and the second link assembly 220 are located between each two immediately adjacent platforms 501 of the three platforms 501.
Each linkage assembly 202 is located at a different horizontal plane, e.g., in fig. 6, the first and second linkage assemblies 210 and 220 are located at different horizontal planes. Specifically, an end of the first driving assembly 10 facing away from the first gear 103 may be provided with an adjusting assembly 70 (shown in fig. 6 or 7), and the adjusting assembly 70 can be used for adjusting the height, i.e., controlling the lifting height of the first driving assembly 10, so that the first gear 103 on the first driving assembly 10 is matched with the second gear 60 on the connecting rod assembly 202 located on different horizontal planes, thereby enabling the connecting rod assemblies 202 to rotate around the fixing shaft 201 respectively.
Specifically, in some embodiments, referring to fig. 6, the adjusting assembly 70 may be a linear motor, wherein a driving shaft of the linear motor may be fixed to the first driving assembly 10, such that the linear motor is operated to drive the first driving assembly 10 to move up and down in a vertical direction, so that the first gear 103 connected to the first driving assembly 10 can match the connecting rod assemblies 202 (e.g., the first connecting rod assembly 210 or the second connecting rod assembly 220 in fig. 6) located on different horizontal planes.
Alternatively, in some other embodiments, as shown with reference to fig. 7, the adjustment assembly 70 may include: a first side frame 701 and a second side frame 702, wherein a middle portion of the first side frame 701 may be rotatably connected to a middle portion of the second side frame 702, so that the overall height of the adjustment assembly 70 may be changed by changing a crossing angle between the first side frame 701 and the second side frame 702, and when the height of the adjustment assembly 70 is lowered or raised, the first driving assembly 10 may be lifted and lowered in a vertical direction, so that the first gear 103 connected to the first driving assembly 10 may be matched with the link assemblies 202 (e.g., the first link assembly 210 or the second link assembly 220 in fig. 6) located on different horizontal planes.
It should be noted that, in the embodiment of the present application, the structure and the implementation manner of the adjusting assembly 70 of the embodiment of the present application are not limited, and are not limited to the above example, as long as the linear movement of the first driving assembly 10 in the vertical direction can be achieved.
In one possible implementation, the first driving assembly 10 may be a motor, such that rotation of the motor rotates the first gear 103, and the first gear 103 rotates the second gear 60 engaged therewith, so as to rotate the connecting rod assembly 202.
Like this, when only one equipment to be charged needs to charge, can be that first link assembly 210 drives to move to the corresponding position around the induction coil 30 of establishing on it and carry out wireless charging to this equipment to be charged, also can be that second link assembly 220 drives to move to the corresponding position around the induction coil 30 of establishing on it and carry out wireless charging to this equipment to be charged, or, can also be that third link assembly 230 drives to move to the corresponding position around the induction coil 30 of establishing on it and carry out wireless charging to this equipment to be charged.
When a plurality of equipment of waiting to charge need charge, can be according to the order of placing and concrete position, a plurality of link assemblies 202 rotate around fixed axle 201 in proper order to the drive moves to corresponding position around establishing induction coil 30 on it and carries out wireless charging to a plurality of equipment of waiting to charge.
Taking the wireless charging apparatus 100 shown in fig. 2 as an example, if two devices to be charged need to be charged, the first link assembly 210 drives the induction coil 30 wound thereon to preferentially match the first device to be charged, and the second link assembly 220 drives the induction coil 30 wound thereon to match the second device to be charged. Taking the wireless charging apparatus 100 shown in fig. 3 as an example, if three devices to be charged need to be charged, the first link assembly 210 drives the induction coil 30 wound thereon to preferentially match a first device to be charged, the second link assembly 220 drives the induction coil 30 wound thereon to match a second device to be charged, and the third link assembly 230 drives the induction coil 30 wound thereon to match a third device to be charged. After all the devices to be charged which need to be charged are matched, the wireless charging device 100 automatically starts wireless charging, and when all the devices to be charged are wirelessly charged simultaneously, the devices to be charged do not affect each other and do not interfere with each other.
It is understood that the wireless charging device 100 can set the rotation sequence or manner of the linkage assembly 202 according to two possible implementations:
one possible implementation is: in the initial state, the link assembly 202 in the wireless charging device 100 is prioritized. Taking fig. 3 as an example, the first link assembly 210 may be set to have a first priority, the second link assembly 220 may be set to have a second priority, and the third link assembly 230 may be set to have a third priority, so that when a device to be charged needs to be wirelessly charged, the first link assembly 210 preferentially rotates around the fixed shaft 201 to drive the induction coil 30 wound thereon to search for the device to be charged.
Another possible implementation is: the wireless charging device 100 is provided with a sensor (not shown in the figure), which can be used to measure the distance between each link assembly 202 and the device to be charged, and when the distance between a link assembly 202 and the device to be charged is determined to be the closest, the link assembly 202 is driven to rotate around the fixed shaft 201, so as to drive the induction coil 30 wound thereon to search for the device to be charged.
EXAMPLE III
Referring to fig. 9 or 10, an embodiment of the present application further provides a wireless charging device 300, where the wireless charging device 300 may include at least: the housing 200 and at least one wireless charging device 100 according to the first or second embodiment, wherein at least one wireless charging device 100 is located inside the housing 200.
In the embodiment of the present application, the number of the wireless charging devices 100 may be one, two, three, or more, which is not limited in the embodiment of the present application. For example, in fig. 9, the wireless charging device 300 may include a housing 200 and a wireless charging apparatus 100 located inside the housing 200. Alternatively, in fig. 10, the wireless charging apparatus 300 may include: a housing 200 and two wireless charging devices 100 located inside the housing 200.
It is understood that when each link assembly 202 in each wireless charging device 100 has at least two links 2021, the device to be charged can be placed at any position on the housing 200, so that after the specific position of the device to be charged is sensed around the induction coil 30 arranged on the link assembly 202, the device to be charged can be rotated around the fixed shaft 201 by the link assembly 202, or at least two links 2021 of the link assembly 202 are relatively extended or shortened, so as to move the induction coil 30 on the link assembly 202 to the position closest to the device to be charged, and charge the device to be charged.
In a specific use process, each link assembly 202 can rotate around the fixed shaft 201, as shown in fig. 9, the wireless charging device 100 in the wireless charging apparatus 300 has a first link assembly 210, a second link assembly 220 and a third link assembly 230. When the length of the first link assembly 210 is fixed as shown in fig. 9, the motion track of the first link assembly 210 may be as shown in a first motion track L1 in fig. 9, when the length of the second link assembly 220 is fixed as shown in fig. 9, the motion track of the second link assembly 220 may be as shown in a second motion track L2 in fig. 9, and similarly, when the length of the third link assembly 230 is fixed as shown in fig. 9, the motion track of the third link assembly 230 may be as shown in a third motion track L3 in fig. 9.
As an optional implementation manner, the housing 200 may be a tea table, a dining table, a shoe cabinet, or the like, and the wireless charging device 100 may be specifically placed inside the tea table, the dining table, or the shoe cabinet, or the wireless charging device 100 may also be placed below a panel of the tea table, a top plate of the dining table, or a panel of the shoe cabinet. Therefore, the charging device is placed on a tea table panel, a dining table panel or a shoe cabinet panel, and wireless charging can be realized.
It is understood that when the space available for the wireless charging device 300 is large, a plurality of wireless charging apparatuses 100 may be placed in the housing 200 of the wireless charging device 300. Therefore, wireless charging can be sensed at all positions, and the distance can be guaranteed, so that the charging efficiency is guaranteed. For example, as shown in fig. 10, two wireless charging devices 100 are placed in the housing 200 of the wireless charging apparatus 300, and each wireless charging device 100 has three link assemblies 202.
In addition, in a practical application scenario, the number of the wireless charging apparatuses 100 may be flexibly adjusted according to the area or the shape of the wireless charging device 300.
It should be noted that, in the embodiment of the present application, the number of the link assemblies 202 in each wireless charging device 100 in the wireless charging apparatus 300 may be two, three, or more, and the embodiment of the present application does not limit this. For example, in fig. 9, the number of the link assemblies 202 of the wireless charging device 100 in the wireless charging apparatus 300 is three, and the wireless charging device 100 can simultaneously charge three apparatuses to be charged. In fig. 10, the number of the link assemblies 202 of two wireless charging devices 100 in the wireless charging apparatus 300 is three, so that two wireless charging devices 100 can respectively and simultaneously charge three apparatuses to be charged.
Specifically, in the embodiment of the present application, when it is detected that the device to be charged is placed on the housing 200 of the wireless charging device 300, the first driving assembly 10 in each wireless charging device 100 operates to control the fixed shaft 201 to rotate, and the fixed shaft 201 rotates to drive the at least two connecting rod assemblies 202 to rotate 360 degrees.
When only one device to be charged needs to be charged, at this time, one of the at least two link assemblies 202 drives the induction coil 30 wound thereon to move to a corresponding position for wireless charging.
In the wireless charging device 300 according to the embodiment of the present application, the wireless charging device 300 at least includes the wireless charging device 100, the wireless charging device 100 drives at least one connecting rod assembly 202 to rotate around the fixing shaft 201 through the first driving assembly 10, and the induction coil 30 is wound on each connecting rod assembly 202, when a certain device to be charged needs to be charged, the at least one connecting rod assembly 202 drives the induction coil 30 wound thereon to rotate around the fixing shaft 201 relatively, so that the induction coil 30 rotates and identifies a specific position of the device to be charged, so as to charge the device to be charged, that is, the position of the device to be charged can be automatically found and the device to be charged can be charged, the problem that only one device to be charged at a fixed position can be charged in the prior art, if the position of the device to be charged moves, the position of the wireless charging device needs to be manually adjusted is avoided, the charging efficiency of the equipment to be charged is improved to a great extent. In addition, when the first driving assembly 10 drives the at least two connecting rod assemblies 202 to rotate around the fixed shaft 201 and each connecting rod assembly 202 is wound with the induction coil 30, if two or more devices to be charged need to be charged, the induction coils 30 on the at least two connecting rod assemblies 202 can respectively charge the devices to be charged simultaneously, so that the charging efficiency of the devices to be charged is improved to a great extent.

The wireless charging system provided by the embodiment of the application, the wireless charging system at least includes a device to be charged and at least one wireless charging device 300, the wireless charging device 300 may include a wireless charging apparatus 100, the wireless charging apparatus 100 drives at least one connecting rod assembly 202 to rotate around a fixing shaft 201 through a first driving assembly 10, and an induction coil 30 is wound on each connecting rod assembly 202, when a certain device to be charged needs to be charged, at least one connecting rod assembly 202 drives the induction coil 30 wound thereon to rotate around the fixing shaft 201 relatively, so that the induction coil 30 rotates and identifies a specific position of the device to be charged to charge the device to be charged, that is, the position of the device to be charged can be automatically found and the device to be charged can be charged, and the prior art can avoid charging only one device to be charged at a fixed position, if the position of the equipment to be charged moves, the position of the wireless charging device needs to be manually adjusted, so that the charging efficiency of the equipment to be charged is improved to a great extent. In addition, when the first driving assembly 10 drives the at least two connecting rod assemblies 202 to rotate around the fixed shaft 201 and each connecting rod assembly 202 is wound with the induction coil 30, if two or more devices to be charged need to be charged, the induction coils 30 on the at least two connecting rod assemblies 202 can respectively charge the devices to be charged simultaneously, so that the charging efficiency of the devices to be charged is improved to a great extent.
