Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a wireless charging stand and a wireless charging device. Background Technology

[0002] With the development of charging technology, wireless chargers have emerged to improve the convenience of charging electronic devices. Wireless chargers eliminate the need for power cords, using electromagnetic waves to wirelessly charge electronic devices.

[0003] Because the coil of a wireless charger needs to communicate with the coil of the electronic device to enable charging, the electronic device's position relative to the wireless charger is critical. Therefore, related technologies use magnetic attraction to hold the electronic device in place for accurate charging. However, after charging is complete, the electronic device cannot detach directly from the wireless charging pad due to the magnetic attraction, requiring the user to manually separate the device and charger, which is inconvenient. Summary of the Invention

[0004] The purpose of this application is to provide a wireless charging stand and a wireless charging device that can solve the problem of inconvenience caused by manually separating the wireless charger and electronic device in related technologies.

[0005] In a first aspect, embodiments of this application provide a wireless charging dock, including a device body, an electromagnetic coil, an actuating switch, and a pressure bearing member. The electromagnetic coil and the pressure bearing member are both disposed on the device body. The pressure bearing member is movable relative to the device body between a first position and a second position. At least a portion of the actuating switch is connected to the pressure bearing member to follow the movement of the pressure bearing member, and the actuating switch is used to control the electromagnetic coil to be energized or de-energized.

[0006] When the pressure-bearing component is in the first position, the actuation switch is electrically turned on to energize the electromagnetic coil; when the pressure-bearing component is in the second position, the actuation switch is electrically turned off to de-energize the electromagnetic coil.

[0007] Secondly, embodiments of this application provide a wireless charging device, including an electronic device and the aforementioned wireless charging dock, wherein the wireless charging dock is used to charge the electronic device;

[0008] When the electronic device is placed on the pressure-bearing member, the pressure-bearing member is in the first position;

[0009] When the electronic device moves away from the pressure-bearing member, the pressure-bearing member moves from the first position to the second position.

[0010] In this embodiment, when charging the electronic device, the device is placed directly on the pressure-bearing component, which is under pressure. The pressure-bearing component moves relative to the device body to a first position, and at least a portion of the actuating switch moves with it. At this time, the actuating switch is electrically activated, energizing the electromagnetic coil and generating a magnetic attraction force. This magnetic attraction force attracts the electronic device, maintaining a fixed relative position between the electronic device and the wireless charging base. This ensures the electronic device is accurately positioned for charging and guarantees effective charging. After charging is complete, the user manually removes the electronic device. During removal, the manual force overcomes the device's weight, causing the pressure-bearing component to switch from a pressurized state to an unpressurized state. The pressure-bearing component moves to a second position, and the actuating switch moves with it. At this time, the actuating switch is electrically deactivated, de-energizing the electromagnetic coil. The magnetic attraction force disappears, and the electronic device is no longer attracted. The electronic device and the wireless charging base separate directly, eliminating the need for a large force to separate them. This simplifies the operation, makes it more convenient, and improves the user experience. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0032] The wireless charging stand and wireless charging device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0033] refer to Figures 1-8 This application discloses a wireless charging stand, which includes a device body 100, an electromagnetic coil 200, an actuating switch 600, and a pressure-bearing component 300. The device body 100 serves as the mounting base for the electromagnetic coil 200 and the pressure-bearing component 300. Both the electromagnetic coil 200 and the pressure-bearing component 300 are located on the device body 100. When the electromagnetic coil 200 is energized, it generates a magnetic attraction force, allowing the wireless charging stand to attract electronic devices.

[0034] The pressure-bearing component 300 is movable relative to the equipment body 100, and at least a portion of the actuating switch 600 is connected to the pressure-bearing component 300. Therefore, at least a portion of the actuating switch 600 moves with the pressure-bearing component 300, and the state of the electromagnetic coil 200 can be switched by the movement of at least a portion of the actuating switch 600. Specifically, the pressure-bearing component 300 can move between a first position and a second position relative to the equipment body 100. The pressure-bearing component 300 can rotate relative to the equipment body 100, and at least a portion of the actuating switch 600 can rotate with the pressure-bearing component 300. Alternatively, the pressure-bearing component 300 can move relative to the equipment body 100, and at least a portion of the actuating switch 600 can move with the pressure-bearing component 300. Optionally, a portion of the actuating switch 600 can be connected to the pressure-bearing component 300, and another portion of the actuating switch 600 can be fixed relative to the equipment body 100. When the pressure-bearing component 300 moves, it drives a portion of the actuating switch 600 to move. Alternatively, the pressure-bearing component 300 can be entirely connected to the actuating switch 600, and when the pressure-bearing component 300 moves, it drives the entire actuating switch 600 to move. In summary, when the pressure-bearing component 300 moves, it drives at least part of the actuating switch 600 to move, so that the actuating switch 600 switches between an electrically connected state and an electrically disconnected state, thereby causing the electromagnetic coil 200 to switch between an energized state and an de-energized state.

[0035] When the pressure-bearing component 300 is in the first position, the actuating switch 600 is electrically turned on, energizing the electromagnetic coil 200. When the pressure-bearing component 300 is in the second position, the actuating switch 600 is electrically turned off, de-energizing the electromagnetic coil 200. In this embodiment, when the pressure-bearing component 300 is in the first position, it means that the pressure-bearing component 300 is subjected to pressure from the electronic device. At this time, the actuating switch 600 is electrically turned on, and the electromagnetic coil 200 is energized to generate a magnetic attraction force. The wireless charging base can then attract the electronic device, maintaining a fixed relative position between the electronic device and the wireless charging base. This helps the electronic device to be accurately positioned in the charging position, ensuring the effective charging process. When the pressure-bearing component 300 is in the second position, it means that the pressure-bearing component 300 is not bearing the pressure of the electronic device. Specifically, after the electronic device is fully charged, during the process of the user taking the electronic device, the manual force gradually overcomes the weight of the electronic device, causing the pressure-bearing component 300 to switch from a pressurized state to an unpressurized state. The pressure-bearing component 300 leaves the first position and moves to the second position. The action switch 600 also switches to the power off state. At this time, the electromagnetic coil 200 is de-energized and the magnetic attraction disappears. The electronic device will no longer be attracted. Therefore, the electronic device and the wireless charging base can be directly separated without having to manually apply a large force to separate the wireless charging base and the electronic device. This simplifies the operation process, makes the wireless charging base more convenient to use, and improves the user experience.

[0036] In an optional embodiment, the electromagnetic coil 200 is a magnetic adsorption coil, and the wireless charging base also includes a charging coil. The charging coil and the electromagnetic coil 200 are simultaneously energized or de-energized. When the charging coil is energized, the wireless charging base charges the electronic device. In this case, charging and adsorption of the electronic device are achieved by different coils, and the state of the charging coil can change according to the state of the electromagnetic coil 200, thereby disconnecting the charging coil when charging is not needed, thus reducing the energy consumption of the wireless charging base. In another optional embodiment, the electromagnetic coil 200 is a charging coil. Thus, switching the state of the electromagnetic coil 200 during the movement of the pressure member 300 not only controls whether the wireless charging base adsorbs the electronic device, but also controls whether the wireless charging base charges the electronic device, avoiding the situation where the electronic device is separated from the wireless charging base while the electromagnetic coil 200 continues to work, reducing the energy consumption of the wireless charging base and saving energy.

[0037] In one alternative embodiment, combined with Figures 2-4As shown, the electromagnetic coil 200 has a break 211, so that the electromagnetic coil 200 has a first end 212 and a second end 213, that is, the electromagnetic coil 200 is a non-closed coil. The actuating switch 600 is located between the first end 212 and the second end 213, and the entire actuating switch 600 moves with the pressure member 300. When the pressure member 300 is in the first position, the actuating switch 600 connects the first end 212 and the second end 213 of the electromagnetic coil 200, so that the electromagnetic coil 200 is in a powered state; when the pressure member 300 is in the second position, the actuating switch 600 is separated from the electromagnetic coil 200, so that the electromagnetic coil 200 is in a de-energized state. In this embodiment, the wireless charging base also includes a power cord, which is electrically connected to the electromagnetic coil 200, and the power cord is used to electrically connect to a power supply device, which can be a fixed power supply or a mobile power supply.

[0038] The actuating switch 600 has a third terminal and a fourth terminal. When the pressure member 300 is in the first position, the third and fourth terminals of the actuating switch 600 are connected to the first terminal 212 and the second terminal 213 of the electromagnetic coil 200, respectively. The electromagnetic coil 200 and the actuating switch 600 form a closed coil. Since the electromagnetic coil 200 is continuously energized, the closed coil is in an energized state, and the electromagnetic coil 200 can generate a magnetic attraction force, allowing the wireless charging base to attract electronic devices. At the same time, the wireless charging base charges the electronic devices. When the pressure member 300 is in the second position, the actuating switch 600 and the electromagnetic coil 200 are separated. At this time, the actuating switch 600 and the electromagnetic coil 200 cannot form a closed coil, that is, the electromagnetic coil 200 cannot be energized, and the electromagnetic coil 200 cannot generate an electromagnetic field, so the electromagnetic coil 200 cannot attract electronic devices.

[0039] In this embodiment, the pressure-bearing component 300 only needs to drive the action switch 600 to move, without driving the overall movement of the electromagnetic coil 200 to switch the state of the electromagnetic coil 200. Therefore, the pressure-bearing component 300 can easily switch between the first position and the second position, and can switch the state of the electromagnetic coil 200 more sensitively.

[0040] When the pressure-bearing component 300 is in the first position, the contact area between the third end of the actuating switch 600 and the first end 212 of the electromagnetic coil 200, and between the fourth end of the actuating switch 600 and the second end 213 of the electromagnetic coil 200, is relatively small. This may prevent the electromagnetic coil 200 and the actuating switch 600 from accurately forming a closed coil. Therefore, in one embodiment, the first end 212 of the electromagnetic coil 200 is provided with a first metal piece 410, the second end 213 of the electromagnetic coil 200 is provided with a second metal piece 420, the actuating switch 600 has a third end and a fourth end, the third end of the actuating switch 600 is provided with a third metal piece 430, and the fourth end of the actuating switch 600 is provided with a fourth metal piece 440. The first metal piece 410 and the second metal piece 420 can extend toward the location of the actuating switch 600, thereby facilitating the connection of the actuating switch 600; the third metal piece 430 can extend toward the first end 212 of the electromagnetic coil 200, and the fourth metal piece 440 can also extend toward the second end 213 of the electromagnetic coil 200, thereby facilitating the connection of the actuating switch 600.

[0041] When the pressure-bearing component 300 is in the first position, the first metal plate 410 contacts the third metal plate 430, and the second metal plate 420 contacts the fourth metal plate 440. At this time, the third terminal of the actuating switch 600 is connected to the first terminal 212 of the electromagnetic coil 200 through the first metal plate 410 and the third metal plate 430, and the fourth terminal of the actuating switch 600 is connected to the second terminal 213 of the electromagnetic coil 200 through the second metal plate 420 and the fourth metal plate 440. Thus, the electromagnetic coil 200, the first metal plate 410, the third metal plate 430, the actuating switch 600, the fourth metal plate 440, and the second metal plate 420 together form a closed coil, and the electromagnetic coil 200 is in an energized state. Figure 4 As shown, when the pressure-bearing component 300 is in the second position, the first metal sheet 410 separates from the third metal sheet 430, and the second metal sheet 420 separates from the fourth metal sheet 440. Specifically, the first metal sheet 410 and the third metal sheet 430 can be stacked, with the top or bottom surface of the first metal sheet 410 in contact with the bottom or top surface of the third metal sheet 430; the second metal sheet 420 and the fourth metal sheet 440 can be stacked so that the top or bottom surface of the second metal sheet 420 is in contact with the bottom or top surface of the fourth metal sheet 440. Thus, the contact area between the first metal sheet 410 and the third metal sheet 430 is relatively large, and the contact area between the second metal sheet 420 and the fourth metal sheet 440 is also relatively large, allowing the first end 212 and the second end 213 of the electromagnetic coil 200 to be accurately connected to the actuating switch 600 to form a closed coil.

[0042] In another optional embodiment, the actuating switch 600 has a contact end 610, and the wireless charging dock also includes a circuit board 500 for supplying power to the electromagnetic coil 200. The circuit board 500 is connected to the device body 100. Optionally, the circuit board 500 may be disposed on the pressure bearing 300, and at least a portion of the circuit board 500 and the actuating switch 600 move together with the pressure bearing 300, i.e., the circuit board 500 is indirectly connected to the device body 100; alternatively, the circuit board 500 may be disposed on the device body 100, i.e., the circuit board 500 is directly connected to the device body. When at least a portion of the actuating switch 600 moves along a first direction, the contact end 610 is pressed, triggering the actuating switch 600. The actuating switch 600 controls the electrical connection between the electromagnetic coil 200 and the circuit board 500, and the electromagnetic coil 200 is in a energized state. When at least a portion of the actuating switch 600 moves along a second direction, the contact end 610 is released, and the actuating switch 600 controls the electrical disconnect between the electromagnetic coil 200 and the circuit board 500, and the electromagnetic coil 200 is in a de-energized state. The first and second directions are opposite. Optionally, the contact end 610 of the actuating switch 600 can be pressed by the device body 100, or by the pressure bearing 300 or the circuit board 500.

[0043] In this embodiment, during the movement of the pressure-bearing component 300, the contact end 610 of the action switch 600 is pressed or released, thereby realizing the electrical conduction or disconnection of the action switch 600, and thus realizing the switching of the state of the electromagnetic coil 200.

[0044] In one optional embodiment, the device body 100 includes a housing 110, and an actuation switch 600 may be disposed in the housing 110. When the pressure member 300 is in the first position, the pressure member 300 presses the contact end 610 of the actuation switch 600, triggering the actuation switch 600. The actuation switch 600 controls the circuit board 500 to conduct electricity with the electromagnetic coil 200, and the electromagnetic coil 200 is in a energized state. When the pressure member 300 is in the second position, there is a gap between the pressure member 300 and the contact end 610 of the actuation switch 600, and the actuation switch 600 is in a non-triggered state. The actuation switch 600 controls the circuit board 500 to disconnect electricity with the electromagnetic coil 200, and the electromagnetic coil 200 is in a de-energized state.

[0045] In another optional embodiment, the actuating switch 600 is disposed on the pressure bearing member 300, and the entire actuating switch 600 can move with the pressure bearing member 300. The contact end 610 can contact the inner wall surface of the housing 110, such as... Figure 7 As shown, when the pressure-bearing component 300 is in the first position, the inner wall surface of the housing 110 presses against the contact end 610 of the actuation switch 600, triggering the actuation switch 600. This activates the electrical connection between the actuation switch 600 control circuit board 500 and the electromagnetic coil 200. Figure 6 As shown, when the pressure-bearing member 300 is in the second position, there is a gap between the contact end 610 of the actuating switch 600 and the inner wall surface of the housing 110, the actuating switch 600 is in an untriggered state, and the control circuit board 500 of the actuating switch 600 is electrically disconnected from the electromagnetic coil 200. Optionally, the actuating switch 600 can be a contact switch.

[0046] In this embodiment, the pressure-bearing component 300 controls the state of the action switch 600 during movement, and the action switch 600 controls whether the electromagnetic coil 200 is in an energized state. Therefore, the electromagnetic coil 200 does not need to be set as a non-closed coil with a break 211, and its reliability when conducting electricity is higher.

[0047] In an optional embodiment, the pressure-bearing member 300 includes a first pressure-bearing plate 310 and a second pressure-bearing plate 320 connected together. At least a portion of the second pressure-bearing plate 320 is disposed within the housing 110, and the second pressure-bearing plate 320 is slidably connected to the housing 110. Optionally, the second pressure-bearing plate 320 includes a first annular portion 322 extending into the housing 110, and the outer wall surface of the first annular portion 322 is in slidable contact with the inner wall surface of the housing 110. The first pressure-bearing plate 310 and the second pressure-bearing plate 320 together form a first receiving space 330. The electromagnetic coil 200, the circuit board 500, and the actuating switch 600 are sequentially disposed within the first receiving space 330, and the second pressure-bearing plate 320 has an opening a for the contact end 610 of the actuating switch 600 to extend out of the first receiving space 330, and the opening a is opposite to the inner wall surface of the housing 110. In this case, the pressure-bearing member 300 is integrally connected to the electromagnetic coil 200.

[0048] Optionally, the second pressure plate 320 further includes a main body plate 321 and a second annular portion 323. The first annular portion 322 and the second annular portion 323 are respectively disposed on both sides of the main body plate 321, and the main body plate 321 is located inside the housing 110. The second annular portion 323 extends outside the housing 110. The main body plate 321 and the second annular portion 323 form a first receiving groove. The first pressure plate 310 covers the port of the second annular portion 323. Therefore, the main body plate 321, the second annular portion 323, and the first pressure plate 310 together form a first receiving space 330. Figure 6 and Figure 7 As shown, the middle part of the main body plate 321 has a bent structure so that a second groove for accommodating the action switch 600 is formed in the middle part of the main body plate 321.

[0049] In this embodiment, the first pressure plate 310 and the second pressure plate 320 are snapped together so that they are detachably connected. In actual application, the electromagnetic coil 200, the circuit board 500 and the actuating switch 600 are connected in sequence first, then the integrated structure composed of the three is installed in the first receiving groove, and finally the first pressure plate 310 is placed over the opening of the first receiving groove.

[0050] The first pressure plate 310 and the second pressure plate 320 drive the electromagnetic coil 200, the circuit board 500 and the actuating switch 600 to move together, which is beneficial for the overall assembly of the electromagnetic coil 200, the circuit board 500 and the actuating switch 600 and avoids the situation where the three are set separately, which would lead to connection difficulties. Moreover, the electromagnetic coil 200, the circuit board 500 and the actuating switch 600 contact each other in the first receiving space 330, avoiding the need to set up lines between the electromagnetic coil 200 and the circuit board 500, and between the circuit board 500 and the actuating switch 600, which helps to simplify the structure of the wireless charging base.

[0051] In an optional embodiment, the housing 110 includes a first housing portion 101 and a second housing portion 102, which are snapped together to detachably connect them. A second pressure plate 320 extends into the second housing portion 102 and slides in contact with it. In practical applications, the second pressure plate 320 is first installed on the second housing portion 102, then the electromagnetic coil 200, circuit board 500, and actuating switch 600 are installed in the first receiving groove, and then the first pressure plate 310 is placed over the opening of the first receiving groove, snapping the first housing portion 101 and the second housing portion 102 together.

[0052] To ensure that the pressure-bearing component 300 can smoothly return from the first position to the second position, the wireless charging dock also includes an elastic component 700. One end of the elastic component 700 is connected to the device body 100, and the other end is connected to the pressure-bearing component 300. When the pressure-bearing component 300 is in the first position, the elastic component 700 undergoes elastic deformation; when the pressure-bearing component 300 is in the second position, the elastic component 700 returns to its elastic deformation. During the process of the electronic device pressing the pressure-bearing component 300, the pressure-bearing component 300 moves from the second position to the first position, and the elastic component 700 undergoes elastic deformation until the pressure-bearing component 300 moves to the first position. The elastic force exerted by the elastic component 700 on the pressure-bearing component 300 is equal to the pressing force exerted by the electronic device on the pressure-bearing component 300. As the pressing force gradually decreases, the elastic force becomes greater than the pressing force, and the elastic component 700 drives the pressure-bearing component 300 to move in the opposite direction until the pressure-bearing component 300 returns to the second position. The elastic component 700 can be a spring.

[0053] By utilizing the elastic element 700, the unpressurized pressure-bearing element 300 can be reset from the first position to the second position, thereby allowing the pressure-bearing element 300 to switch between the first and second positions, ensuring that the electromagnetic coil 200 can smoothly switch between the energized and de-energized states.

[0054] In one alternative embodiment, such as Figure 4 and Figure 5 As shown, the number of elastic elements 700 can be one; or, as... Figure 6 and Figure 7 As shown, there are multiple elastic elements 700, which are spaced apart between the pressure-bearing member 300 and the device body 100. In this embodiment, multiple elastic elements 700 are arranged around the contact end 610 of the actuating switch 600. Optionally, when the pressure-bearing member 300 is connected to a part of the actuating switch 600, there can be one elastic element 700; when the pressure-bearing member 300 is connected to the entire actuating switch 600, there can be multiple elastic elements 700. In this way, multiple elastic elements 700 apply elastic forces to the pressure-bearing member 300, that is, multiple positions of the pressure-bearing member 300 bear elastic forces, the pressure-bearing member 300 is subjected to more uniform force, which is beneficial for the pressure-bearing member 300 to stably switch from the first position to the second position.

[0055] In optional embodiments, such as Figures 1-3 As shown, the main body 100 of the device includes a housing 110, which includes a supporting bottom wall 111, an annular side wall 112, and a bending portion 113. The supporting bottom wall 111 is connected to the annular side wall 112, and the supporting bottom wall 111 is provided with a mounting hole 130. The pressure-bearing member 300 is movably disposed at the mounting hole 130. The supporting bottom wall 111 and the annular side wall 112 together form a second receiving groove 120. The electromagnetic coil 200, the elastic member 700, and the bending portion 113 are all disposed in the second receiving groove 120. One end of the bending portion 113 is connected to the supporting bottom wall 111, and the other end of the bending portion 113 is connected to the elastic member 700. The bending portion 113 facilitates the fixing of one end of the elastic member 700. In this embodiment, the electromagnetic coil 200 is arranged around the pressure-bearing member 300, the elastic member 700, and the bending portion 113, making full use of the space in the second receiving groove 120, improving space utilization, and reducing the space occupied by the wireless charging base. Optionally, the supporting bottom wall 111, the annular side wall 112, and the bent portion 113 can be integrally formed structures.

[0056] In one alternative embodiment, such as Figure 6 and Figure 7As shown, the main body 100 of the device includes a housing 110, which has a mounting hole 130. A pressure-bearing member 300 is disposed at the mounting hole 130, and the pressure-bearing member 300 has a first bearing surface 311 for supporting the electronic device. The housing 110 is located on the side of the pressure-bearing member 300 opposite to the first bearing surface 311. Optionally, along a direction perpendicular to the first bearing surface 311, the orthographic projection of the first bearing surface 311 can cover the orthographic projection of the housing 110, that is, the area of ​​the first bearing surface 311 is large, and the first bearing surface 311 is sufficient to support the electronic device alone. In this embodiment, the first pressure plate 310 has the first bearing surface 311, and the second pressure plate 320 is disposed at the mounting hole 130, and the outer wall surface of the second annular portion 323 of the second pressure plate 320 slides in contact with the hole wall of the mounting hole 130. In this embodiment, since the housing 110 is located on the side of the pressure-bearing member 300 away from the first bearing surface 311, the first bearing surface 311 can always support the electronic device alone, so that the pressure-bearing member 300 can accurately bear the force exerted on it by the electronic device and ensure that the pressure-bearing member 300 moves in a timely manner.

[0057] In another alternative embodiment, such as Figure 4 and Figure 5 As shown, the pressure-bearing component 300 has a first bearing surface 311. The equipment body 100 includes a shell 110, and the outer wall surface of the shell 110 includes a second bearing surface 140. The second bearing surface 140 is provided with a mounting hole 130, which communicates with a second receiving groove 120. The pressure-bearing component 300 is disposed at the mounting hole 130. Figure 5 As shown, when the pressure-bearing component 300 is in the first position, the first bearing surface 311 and the second bearing surface 140 are flush. At this time, the first bearing surface 311 and the second bearing surface 140 jointly support the electronic device, preventing the pressure-bearing component 300 from being subjected to excessive pressure and causing excessive movement of the pressure-bearing component 300. When the pressure-bearing component 300 is in the second position, the first bearing surface 311 protrudes from the second bearing surface 140. At this time, the pressure-bearing component 300 can accurately withstand the force exerted on it by the electronic device, ensuring that the pressure-bearing component 300 can move in a timely manner.

[0058] In the scheme of this application, such as Figure 4 and Figure 5As shown, the wireless charging dock also includes a locking member 810 and a locking groove 820. The locking member 810 is movably connected to the device body 100, and the locking groove 820 is formed in the pressure-bearing member 300. The locking member 810 can extend into the locking groove 820 to keep the pressure-bearing member 300 in a first position. Optionally, the device body 100 includes a housing 110, and the locking member 810 can be rotatably connected to the housing 110 or slidably connected to the housing 110. In short, the locking member 810 can extend into the locking groove 820 during movement. When the user carries or moves the wireless charging dock and the electronic device, the weight of the electronic device may not act on the pressure-bearing member 300. At this time, in order to ensure that the electromagnetic coil 200 is energized, the locking member 810 extends into the locking groove 820 to keep the pressure-bearing member 300 in the first position, thereby ensuring that the wireless charging dock can charge the electronic device smoothly and expanding the application scenarios of the wireless charging dock.

[0059] In optional embodiments, such as Figure 1 As shown, the main body 100 of the device includes a housing 110, and a locking member 810 is disposed on the inner wall surface of the housing 110. Alternatively, a first groove 150 is provided on the outer surface of the housing 110, and the locking member 810 is exposed within the first groove 150. In this embodiment, the first groove 150 is disposed on the second bearing surface 140 of the housing 110. Thus, the user can directly and manually insert into the first groove 150 and operate the locking member 810 to easily lock or unlock the pressure-bearing member 300.

[0060] In one optional embodiment, the main body 100 includes a housing 110, at least a portion of the pressure-bearing member 300 is disposed within the housing 110, one of the housing 110 and the pressure-bearing member 300 is provided with a limiting groove 920, and the other is provided with a limiting protrusion 910. The limiting protrusion 910 extends into the limiting groove 920, and the limiting groove 920 is provided with opposing first limiting surfaces 921 and second limiting surfaces 922. The limiting protrusion 910 is provided with opposing third limiting surfaces 911 and fourth limiting surfaces 912. The first limiting surface 921 can be limited and engaged with the third limiting surface 911, and the second limiting surface 922 can be limited and engaged with the fourth limiting surface 912.

[0061] Optionally, such as Figure 4 and Figure 5 As shown, a limiting groove 920 is disposed on the pressure-bearing member 300, and a limiting protrusion 910 is disposed on the housing 110. When the pressure-bearing member 300 is in the first position, the first limiting surface 921 contacts the third limiting surface 911; when the pressure-bearing member 300 is in the second position, the second limiting surface 922 contacts the fourth limiting surface 912. Optionally, as... Figure 6 and Figure 7As shown, part of the second pressure plate 320 is a limiting protrusion 910, and the inner wall surface of the housing 110 forms a limiting groove 920. The side of the main plate 321 of the second pressure plate 320 facing away from the first annular portion 322 is the third limiting surface 911, and the side of the inner wall surface of the housing 110 facing the third limiting surface 911 is the fourth limiting surface 912. When the pressure member 300 is in the second position, the third limiting surface 911 and the fourth limiting surface 912 are in limiting contact, that is, the main plate 321 is in limiting contact with the inner wall surface of the housing 110.

[0062] The movement stroke of the pressure-bearing component 300 is limited by the limiting groove 920 and the limiting protrusion 910 to prevent the pressure-bearing component 300 from moving too far and to ensure that the pressure-bearing component 300 can be accurately positioned in the first or second position.

[0063] Based on the wireless charging stand disclosed in this application, this application also discloses a wireless charging device. The disclosed wireless charging device includes an electronic device and the wireless charging stand described in the above embodiments. The wireless charging stand is used to charge the electronic device. When the electronic device is placed on the pressure member 300, the pressure member 300 is in a first position; when the electronic device moves away from the pressure member 300, the pressure member 300 moves from the first position to a second position. Specifically, when the electronic device is placed on the pressure member 300, the electronic device applies a force to the pressure member 300, and the pressure member 300 is compressed and moves to the first position; when the electronic device moves away from the pressure member 300, the pressure member 300 is no longer compressed, and the pressure member 300 can return to the first position.

[0064] Thus, the pressure-bearing component 300 of the wireless charging device drives at least part of the action switch 600 to move, thereby realizing the electrical conduction and disconnection of the action switch 600, and ultimately switching the electromagnetic coil 200 between the energized and de-energized states. During this process, no manual force is required to separate the wireless charging base and the electronic device, simplifying the operation and making the use of the wireless charging base more convenient.
