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] However, existing wireless charging devices require the electronic devices to be stacked on the surface of the wireless charging device's casing when charging electronic devices. This results in a large amount of heat generated by the wireless charging device and electronic devices during charging that cannot be dissipated in time, leading to high charging temperatures and low charging power.

[0020] Compared with the prior art, the embodiments of this utility model have at least the following beneficial effects:

[0021] In this embodiment of the invention, a receiving groove is recessed on the surface of the first housing, and the first wireless charging component has a first charging position. A mounting cavity is provided on the outer shell of the first wireless charging component, and a first transmitting coil is provided in the mounting cavity. Thus, the first charging position is located on the side of the outer shell away from the first housing, allowing electronic devices to be placed in the first charging position for wireless charging. The first wireless charging component is movably connected to the first housing to move along the depth direction of the receiving groove to a first position or a second position. When the electronic device is charged using a wireless charging device, the first wireless charging component can move relative to the first housing to move along the depth direction of the receiving groove to a second position. At this time, the first wireless charging component extends out of the receiving groove, and a heat dissipation vent is provided on the side of the outer shell facing the first housing. The heat dissipation vent communicates with the mounting cavity, allowing electronic devices to be placed in the first charging position for charging. The large amount of heat generated by the wireless charging device and the electronic device during charging can be dissipated to the outside of the mounting cavity in a timely manner through the heat dissipation vent. Furthermore, the extension of the first wireless charging component out of the receiving groove increases the distance between the heat dissipation vent and the wall of the receiving groove, which is more conducive to heat dissipation, resulting in a lower charging temperature and higher charging power.

[0022] When charging is not required, the first wireless charging component can move relative to the first housing to be displaced to the first position along the depth direction of the receiving groove. At this time, the first wireless charging component is stored in the receiving groove, which can reduce the space occupied by the wireless charging component and make the overall size of the wireless charging device smaller.

[0044] This utility model discloses a wireless charging device. The large amount of heat generated by the wireless charging device and electronic devices during charging can be dissipated in time, resulting in a low charging temperature and high charging power.

[0045] Please see Figures 1 to 3 This 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 and a first wireless charging component 20. A receiving groove 10a is recessed on the surface of the first housing 10. A first charging position is provided on the first wireless charging component 20. The first wireless charging component 20 is movably connected to the first housing 10 to be displaced along the depth direction x of the receiving groove 10a to a first position or a second position. Figure 4 and Figure 5 The first wireless charging component 20 includes a housing 21 and a first transmitting coil 22. The housing 21 has a mounting cavity 21a. The first transmitting coil 22 is located in the mounting cavity 21a. The first charging position is located on the side of the housing 21 away from the first housing 10. The housing 21 has a heat dissipation vent 21b on the side facing the first housing 10. The heat dissipation vent 21b is connected to the mounting cavity 21a.

[0046] Specifically, when the first wireless charging component 20 is in the first position, the first wireless charging component 20 is housed in the receiving groove 10a, and when the first wireless charging component 20 is in the second position, the first wireless charging component 20 extends out of the receiving groove 10a.

[0047] The first charging position refers to the location for placing an electronic device. For example, if an electronic device is placed in the first charging position, it can be charged using the first wireless charging component 20.

[0048] Optionally, the electronic device may include a smartwatch, headphones, a mobile phone, etc. For example, the first charging position is used to place a mobile phone and to charge the mobile phone using the first wireless charging component 20.

[0049] like Figure 1 As shown, Figure 1 The first wireless charging component 20 is shown in a first position. (See diagram.) Figure 2 As shown, Figure 2 The first wireless charging component 20 is shown in the second position.

[0050] In this embodiment, a receiving groove 10a is recessed on the surface of the first housing 10, and the first wireless charging assembly 20 has a first charging position. A mounting cavity 21a is provided on the outer shell 21 of the first wireless charging assembly 20, and a first transmitting coil 22 is provided in the mounting cavity 21a. Thus, the first charging position is located on the side of the outer shell 21 away from the first housing 10, so that electronic devices can be placed in the first charging position for wireless charging. The first wireless charging assembly 20 is movably connected to the first housing 10 to be displaced along the depth direction x of the receiving groove 10a to a first position or a second position. Therefore, when the wireless charging device 100 is used to charge the electronic device, the first wireless charging assembly 20 can move relative to the first housing 10 to the receiving groove 10a. When the depth direction x of a is shifted to the second position, the first wireless charging component 20 extends out of the receiving groove 10a, and the outer shell 21 is provided with a heat dissipation vent 21b on the side facing the first shell 10. The heat dissipation vent 21b is connected to the mounting cavity 21a, and an electronic device can be placed in the first charging position. The electronic device can then be charged using the first wireless charging component 20. The large amount of heat generated by the wireless charging device 100 and the electronic device during charging can be dissipated from the heat dissipation vent 21b to the outside of the mounting cavity 21a in a timely manner. Furthermore, the extension of the first wireless charging component 20 out of the receiving groove 10a increases the distance between the heat dissipation vent 21b and the wall of the receiving groove 10a, which is more conducive to heat dissipation, resulting in a lower charging temperature and higher charging power.

[0051] When no charging is needed, the first wireless charging component 20 can move relative to the first housing 10 to be displaced to the first position along the depth direction x of the receiving groove 10a. At this time, the first wireless charging component 20 is housed in the receiving groove 10a, which can reduce the space occupied by the wireless charging component and make the overall volume of the wireless charging device 100 smaller.

[0052] For example, when the first wireless charging component 20 is in the second position, a heat dissipation channel a is formed between the outer shell 21 and the wall of the receiving groove 10a, and the heat dissipation channel a connects to the outside. In this way, after the large amount of heat generated by the wireless charging device 100 and the electronic device during charging is dissipated from the heat dissipation port 21b to the outside of the mounting cavity 21a, it can be dissipated to the outside through the heat dissipation channel a formed between the outer shell 21 and the wall of the receiving groove 10a, thereby avoiding the accumulation of heat between the heat dissipation port 21b and the receiving groove 10a and improving heat dissipation efficiency.

[0053] In some embodiments, the wireless charging device 100 further includes a second housing 30, which 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 receiving groove 10a, and the first wireless charging component 20 is located in a first position. When the second housing 30 is in the open state relative to the first housing 10, the first wireless charging component 20 is located in a second position. Thus, by rotatably connecting the first housing 10 and the second housing 30, the first housing 10 and the second housing 30 can rotate relative to each other, and 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 open state relative to the first housing 10, the first wireless charging component 20 is located in the second position. At this time, the first wireless charging component 20 extends out of the receiving groove 10a and forms a heat dissipation channel a between it and the receiving groove 10a, so that electronic devices can be placed in the first charging position, thereby charging the electronic devices using the first wireless charging component 20. Moreover, the large amount of heat generated by the wireless charging device 100 and the electronic devices during charging can be dissipated in time from the heat dissipation channel a, resulting in a low charging temperature and a high charging power.

[0054] When the second housing 30 is closed relative to the first housing 10, the second housing 30 covers the first housing 10 and blocks the receiving groove 10a. The first wireless charging component 20 is located in the first position. At this time, the first wireless charging component 20 is stored in the receiving groove 10a, which can reduce the space occupied by the wireless charging component and make the overall volume of the wireless charging device 100 smaller.

[0055] like Figure 6 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 1 and 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.

[0056] In some embodiments, such as Figure 5 and Figure 7As shown, the wireless charging device 100 includes a movable mechanism 40. A first wireless charging component 20 is connected to a first housing 10 via the movable mechanism 40 to be displaced to a first position or a second position along the depth direction x of the receiving groove 10a. Thus, the first wireless charging component 20 is connected to the first housing 10 via the movable mechanism 40, allowing the first wireless charging component 20 to be displaced relative to the first housing 10 along the depth direction x of the receiving groove 10a to the first position or the second position.

[0057] Optionally, the moving mechanism 40 may employ sliding, rotating, telescopic, or compound motion mechanisms to enable the first wireless charging component 20 to move relative to the first housing 10. The choice can be made according to the actual situation, and this embodiment does not impose specific limitations on this.

[0058] For example, such as Figure 5 , Figure 8 and Figure 9 As shown, the active mechanism 40 includes a first rotating member 41 and a second rotating member 42. One end of the first rotating member 41 is rotatably connected to the first housing 10 about a first axis α. The other end of the first rotating member 41 is rotatably connected to one end of the second rotating member 42 about a second axis β. The end of the second rotating member 42 away from the first rotating member 41 is rotatably connected to the first wireless charging component 20 about a third axis γ. The first axis α, the second axis β and the third axis γ extend in the same direction and are perpendicular to the depth direction x. Thus, the first housing 10, the first rotating member 41, the second rotating member 42, and the first wireless charging assembly 20 are sequentially rotatably connected, and the first axis α, the second axis β, and the third axis γ extend in the same direction and are perpendicular to the depth direction x. During the process of the first wireless charging assembly 20 interacting with the first housing 10 to move to the first or second position along the depth direction x of the receiving groove 10a, the first wireless charging assembly 20 rotates relative to the second rotating member 42 around the third axis γ, the second rotating member 42 rotates relative to the first rotating member 41 around the second axis β, and the first rotating member 41 rotates relative to the first housing 10 around the first axis α. That is, the first wireless charging assembly 20 undergoes a compound rotational motion relative to the first housing 10, thereby forming a displacement along the depth direction x.

[0059] Furthermore, taking the displacement of the first wireless charging component 20 relative to the first housing 10 along the depth direction x of the receiving groove 10a from the second position to the first position as an example, the first rotating member 41 rotates relative to the first housing 10 around the first axis α, the end of the first wireless charging component 20 away from the first axis α presses down along the direction close to the first housing 10, and the end of the first wireless charging component 20 close to the first axis α tilts up along the direction away from the first housing 10, forming a lever motion. Then, by the first wireless charging component 20 rotating relative to the second rotating member 42 around the third axis γ, and the second rotating member 42 rotating relative to the first rotating member 41 around the second axis β, the tilt angle of the first wireless charging component 20 relative to the first housing 10 is corrected, so that the first wireless charging component 20 is housed in the receiving groove 10a when it is displaced to the first position. Thus, during the process of the first wireless charging component 20 displacing relative to the first housing 10 along the depth direction x of the receiving groove 10a from the second position to the first position, the lever principle can reduce the required force and lower the resistance to changing the position of the first wireless charging component 20.

[0060] In some embodiments, the other end of the first rotating member 41 is rotatably connected to one end of the second rotating member 42 via a first rotating shaft 43. The movable mechanism 40 further includes a first torsion spring 44, which is sleeved on the first rotating shaft 43. The first torsion spring 44 has two first elastic arms 44a, which respectively abut against the first rotating member 41 and the second rotating member 42. In this way, the second rotating member 42 can rotate relative to the first rotating member 41 about the second axis β via the first rotating shaft 43. Furthermore, by using a first torsion spring 44 sleeved on the first rotating shaft 43, and with the two first elastic arms 44a of the first torsion spring 44 respectively abutting against the first rotating member 41 and the second rotating member 42, when the first wireless charging component 20 is displaced from the second position to the first position relative to the first housing 10 along the depth direction x of the receiving groove 10a, the second rotating member 42 rotates relative to the first rotating member 41 around the second axis β. At this time, the second rotating member 42 and the first rotating member 41 press against the two first elastic arms 44a, so that the first torsion spring 44 has an elastic force. This elastic force is used to realize the reset of the second rotating member 42 relative to the first rotating member 41 around the second axis β, that is, it can occur when the first wireless charging component 20 is displaced from the first position to the second position relative to the first housing 10 along the depth direction x of the receiving groove 10a.

[0061] For example, such as Figure 5 and Figure 7As shown, the first housing 10 has a receiving cavity 10b, and the first rotating member 41 and the second rotating member 42 are located in the receiving cavity 10b. The bottom of the receiving groove 10a has a through hole 10c, which connects to the receiving cavity 10b. The movable mechanism 40 also includes a third rotating member 45. One end of the third rotating member 45 is located on the side of the first wireless charging assembly 20 facing the through hole 10c, and the other end of the third rotating member 45 extends through the through hole 10c to the receiving cavity 10b and is rotatably connected to the end of the second rotating member 42 away from the first rotating member 41. In this way, by having the first rotating member 41 and the second rotating member 42 located in the receiving cavity 10b, the space occupied by the first rotating member 41 and the second rotating member 42 can be reduced by utilizing the receiving cavity 10b, thereby reducing the overall volume of the wireless charging device 100. On the other hand, the other end of the third rotating member 45 extends through the through hole 10c to the receiving cavity 10b and is rotatably connected to the end of the second rotating member 42 away from the first rotating member 41, so that the first wireless charging component 20 rotates relative to the second rotating member 42 around the third axis γ. During the process of the first wireless charging component 20 moving from the second position to the first position relative to the first housing 10 along the depth direction x of the receiving groove 10a, the third rotating member 45 rotates relative to the second rotating member 42 around the third axis γ to drive the first wireless charging component 20 to rotate together.

[0062] In some embodiments, such as Figure 8 and Figure 9 As shown, the other end of the third rotating member 45 is rotatably connected to the end of the second rotating member 42 away from the first rotating member 41 via the second rotating shaft 46. The movable mechanism 40 also includes a second torsion spring 47, which is sleeved on the second rotating shaft 46. The second torsion spring 47 has two second elastic arms 47a, which respectively abut against the second rotating member 42 and the third rotating member 45. The second rotating shaft 46 enables the third rotating member 45 to rotate relative to the second rotating member 42 around the third axis γ. Furthermore, by using a second torsion spring 47 sleeved on the second rotating shaft 46, and with the two second elastic arms 47a of the second torsion spring 47 respectively abutting against the second rotating member 42 and the third rotating member 45, when the first wireless charging component 20 is displaced from the second position to the first position relative to the first housing 10 along the depth direction x of the receiving groove 10a, the third rotating member 45 rotates relative to the second rotating member 42 around the third axis γ to drive the first wireless charging component 20 to rotate together. At this time, the third rotating member 45 and the second rotating member 42 squeeze the two second elastic arms 47a, so that the second torsion spring 47 has an elastic force. This elastic force is used to realize the reset of the third rotating member 45 relative to the second rotating member 42 around the third axis γ, that is, it can occur when the first wireless charging component 20 is displaced from the first position to the second position relative to the first housing 10 along the depth direction x of the receiving groove 10a.

[0063] For example, the first charging position is located on the side of the first wireless charging assembly 20 away from the first housing 10. When the first wireless charging assembly 20 is in the second position, the extension directions of the two second elastic arms 47a are perpendicular to each other, and the extension direction of the second elastic arm 47a abutting the third rotating member 45 is the same as the depth direction x. In this way, when the first wireless charging assembly 20 is in the second position, the electronic device can be placed in the first charging position, that is, placed on the side of the first wireless charging assembly 20 away from the first housing 10 for charging. At this time, by utilizing the fact that the extension directions of the two second elastic arms 47a are perpendicular to each other, and the extension direction of the second elastic arm 47a abutting the third rotating member 45 is the same as the depth direction x, the second torsion spring 47 can provide a supporting force to the first wireless charging assembly 20, so that the first wireless charging assembly 20 can stably support the electronic device.

[0064] In some embodiments, such as Figure 7 and Figure 10 As shown, the wireless charging device 100 also includes a motherboard 50, which is disposed in the receiving cavity 10b. The motherboard 50 has a clearance notch 50a, which is provided corresponding to the first rotating member 41 and the second rotating member 42. The wiring of the first wireless charging component 20 extends through the through hole 10c to the receiving cavity 10b and is electrically connected to the motherboard 50. In this way, by placing the motherboard 50 in the receiving cavity 10b and using the motherboard 50 to electrically connect with the wiring of the first wireless charging component 20, the motherboard 50 can control the first wireless charging component 20. Furthermore, by using the clearance notch 50a of the motherboard 50 to avoid interference between the first rotating member 41 and the second rotating member 42 and the motherboard 50 during rotation, the interference between the first rotating member 41 and the second rotating member 42 and the motherboard 50 can be avoided.

[0065] For example, a plurality of electronic components 51 are provided on the side of the motherboard 50 away from the first wireless charging component 20. In this way, by placing the plurality of electronic components 51 on the side of the motherboard 50 away from the first wireless charging component 20, it is possible to avoid the heat generated by the electronic components 51 and the heat generated by the first wireless charging component 20 from accumulating between the first wireless charging component 20 and the motherboard 50, which would cause the operating temperature of the wireless charging device 100 to be too high.

[0066] In some embodiments, such as Figure 11As shown, the wireless charging device 100 also includes a connector 60, which is rotatably connected to the first housing 10. The second housing 30 is rotatably connected to the connector 60. When the second housing 30 switches from an open state to a closed state relative to the first housing 10, the first wireless charging component 20 rotates relative to the second rotating member 42, the second rotating member 42 rotates relative to the first rotating member 41, and the first rotating member 41 rotates relative to the first housing 10, causing the first wireless charging component 20 to move from a second position to a first position. Thus, the state switching of the second housing 30 relative to the first housing 10 is linked to the movement of the first wireless charging component 20 relative to the first housing 10. When the second housing 30 switches from an open state to a closed state relative to the first housing 10, the first wireless charging component 20 moves relative to the first housing 10, switching from extending out of the placement slot to being stored in the placement slot. At this time, the wireless charging device 100 can be stored. This improves the efficiency of the wireless charging device 100 in switching between charging and not charging, resulting in a high degree of automation.

[0067] For example, such as Figure 11 and Figure 12 As shown, the wireless charging device 100 also includes a first bushing 71, a first rotating shaft 72, a second bushing 73, and a second rotating shaft 74. The first bushing 71 is located at one end of the connector 60 facing the first housing 10. One end of the first rotating shaft 72 is rotatably connected to the first housing 10, and the other end of the first rotating shaft 72 is rotatably connected to the first bushing 71 around the first axis α. The first rotating member 41 is fixedly connected to the first rotating shaft 72. The second bushing 73 is located at one end of the connector 60 facing the second housing 30. One end of the second rotating shaft 74 is located inside the second housing 30, and the other end of the second rotating shaft 74 is rotatably connected to the second bushing 73. Thus, on the one hand, by providing a first bushing 71 at the end of the connector 60 facing the first housing 10, and rotatably connecting one end of the first rotating shaft 72 to the first housing 10, with the other end of the first rotating shaft 72 rotatably connected to the first bushing 71 around the first axis α, and the first rotating member 41 fixedly connected to the first rotating shaft 72, a rotatable connection between the first rotating member 41 and the first housing 10 is achieved. When the first rotating member 41 rotates relative to the first housing 10 until it abuts against the first housing 10, it can drive the first housing 10 to rotate around the first axis α relative to the connector 60. On the other hand, by providing a second bushing 73 at the end of the connector 60 facing the second housing 30, and rotatably connecting one end of the second rotating shaft 74 to the second bushing 73, a rotatable connection between the second housing 30 and the connector 60 is achieved.

[0068] In some embodiments, the frictional force of the other end of the first rotating shaft 72 rotating relative to the first bushing 71 and the frictional force of the other end of the second rotating shaft 74 rotating relative to the second bushing 73 are both greater than the frictional force of one end of the first rotating shaft 72 rotating relative to the first housing 10. Thus, because the frictional force of the other end of the first rotating shaft 72 rotating relative to the first bushing 71 is greater than the frictional force of one end of the first rotating shaft 72 rotating relative to the first housing 10, when the first housing 10 and the second housing 30 are subjected to external forces, the rotation of one end of the first rotating shaft 72 relative to the first housing 10 takes precedence over the rotation of the other end of the first rotating shaft 72 relative to the first bushing 71. Similarly, because the frictional force of the other end of the second rotating shaft 74 rotating relative to the second bushing 73 is greater than the frictional force of one end of the first rotating shaft 72 rotating relative to the first housing 10, when the first housing 10 and the second housing 30 are subjected to external forces, the rotation of one end of the first rotating shaft 72 relative to the first housing 10 takes precedence over the rotation of the other end of the second rotating shaft 74 relative to the second bushing 73.

[0069] Based on this, the specific process of linking the state switching of the second housing 30 relative to the first housing 10 with the movement of the first wireless charging component 20 relative to the first housing 10 in this embodiment is as follows:

[0070] During the process of the second housing 30 switching from the open state to the closed state relative to the first housing 10, since one end of the first rotating shaft 72 has a higher rotation priority relative to the first housing 10, the rotation of the first rotating shaft 72 relative to the first housing 10 drives the first rotating member 41 to rotate relative to the first housing 10 around the first axis α. The end of the first wireless charging component 20 away from the first axis α presses down in the direction close to the first housing 10, and the end of the first wireless charging component 20 close to the first axis α tilts up in the direction away from the first housing 10. When the first rotating member 41 rotates relative to the first housing 10 to abut against the first housing 10, the first rotating member 41 and the first housing 10 can no longer rotate relative to each other. At this time, the first rotating shaft 72 rotates relative to the first bushing 71, and drives the first rotating member 41 and the first housing 10 to rotate together around the first axis α relative to the connecting member 60. At the same time, the second rotating shaft 74 rotates relative to the second bushing 73, and drives the second housing 30 to rotate relative to the connecting member 60. When the second housing 30 and the first housing 10 rotate relative to the connector 60 until the second housing 30 abuts against the end of the first wireless charging component 20 near the first axis α, the second housing 30 pushes the first wireless charging component 20. The first wireless charging component 20 rotates relative to the second rotating member 42 around the third axis γ, and the second rotating member 42 rotates relative to the first rotating member 41 around the second axis β to correct the tilt angle of the first wireless charging component 20 relative to the first housing 10, so that the first wireless charging component 20 is housed in the receiving groove 10a when it is displaced to the first position.

[0071] For example, a first fixing part 72a is provided at one end of the first rotating shaft 72 located inside the first housing 10. The first fixing part 72a extends outward along the radial direction of the first rotating shaft 72 and is fixedly connected to the first rotating member 41. In this way, by providing the first fixing part 72a at one end of the first rotating shaft 72 located inside the first housing 10 and fixing the first fixing part 72a to the first rotating member 41, the first rotating shaft 72 can drive the first rotating member 41 to rotate relative to the first housing 10 when it rotates relative to the first housing 10. When the first rotating member 41 rotates relative to the first housing 10 to the point that the first rotating member 41 abuts against the first housing 10, the first rotating shaft 72, the first rotating member 41, and the first housing 10 remain relatively fixed, while the first rotating shaft 72 continues to rotate relative to the first bushing 71. At this time, the first rotating member 41 and the first housing 10 rotate with the first rotating shaft 72 relative to the connecting member 60.

[0072] In some embodiments, such as Figure 13 As 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.

[0073] 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.

[0074] This utility model embodiment provides a wireless charging device 100. A receiving groove 10a is recessed on the surface of a first housing 10. A first wireless charging component 20 has a first charging position. A mounting cavity 21a is provided on the outer shell 21 of the first wireless charging component 20, and a first transmitting coil 22 is disposed in the mounting cavity 21a. The first charging position is located on the side of the outer shell 21 away from the first housing 10, allowing electronic devices to be placed in the first charging position for wireless charging. The first wireless charging component 20 is movably connected to the first housing 10 to be displaced along the depth direction x of the receiving groove 10a to a first position or a second position. Therefore, when using the wireless charging device 100 to charge an electronic device, the first wireless charging component 20 can be positioned relative to the first housing 10. The device moves to the second position along the depth direction x of the receiving groove 10a. At this time, the first wireless charging component 20 extends out of the receiving groove 10a, and the outer shell 21 is provided with a heat dissipation vent 21b on the side facing the first shell 10. The heat dissipation vent 21b communicates with the mounting cavity 21a, allowing electronic devices to be placed in the first charging position. The first wireless charging component 20 can then charge the electronic devices. The large amount of heat generated by the wireless charging device 100 and the electronic devices during charging can be dissipated from the heat dissipation vent 21b to the outside of the mounting cavity 21a in a timely manner. Furthermore, the extension of the first wireless charging component 20 out of the receiving groove 10a increases the distance between the heat dissipation vent 21b and the wall of the receiving groove 10a, which is more conducive to heat dissipation, resulting in a lower charging temperature and higher charging power.

[0075] When no charging is needed, the first wireless charging component 20 can move relative to the first housing 10 to be displaced to the first position along the depth direction x of the receiving groove 10a. At this time, the first wireless charging component 20 is housed in the receiving groove 10a, which can reduce the space occupied by the wireless charging component and make the overall volume of the wireless charging device 100 smaller.

[0076] The above provides a detailed description of a wireless charging device disclosed in the embodiments of this utility model. This article uses specific examples to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the wireless charging device and its core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
