Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a wireless charging stand. Background Technology

[0002] Wireless charging stands utilize the principle of electromagnetic induction for charging. When charging mobile devices using a wireless charging stand, there's no need to connect the stand to the device via a charging cable, making it more compatible and versatile. However, whether charging a mobile device wirelessly or via a wired charger, the device generates heat during the charging process. When charging a mobile device wirelessly, the charging efficiency decreases as the device's temperature rises. Therefore, a wireless charging stand capable of rapidly dissipating heat and cooling the mobile device is needed to improve its charging efficiency. Utility Model Content

[0003] This application provides a wireless charging stand that can quickly dissipate heat and cool down the object being charged, thereby increasing the speed of wireless charging.

[0004] The wireless charging bracket provided in this application includes: a base, a wireless charging component, an airflow generator, and a fixing component. The base has a receiving cavity; the wireless charging component is disposed within the receiving cavity; the airflow generator is disposed on the base; the fixing component is disposed on the base, forming a receiving space for accommodating the object to be charged between the fixing component and the base. The fixing component has an airflow channel, with the air outlet of the airflow channel facing the receiving space. The airflow generated by the airflow generator flows through the airflow channel and from the air outlet to the receiving space.

[0005] The wireless charging stand provided in this application embodiment has a fixing component on the base, which, together with the base, forms an open accommodating space. This provides a placement position for the object to be charged and restricts its movement relative to the wireless charging stand. Furthermore, an airflow generator is provided on the base to generate airflow for the object to be charged, which helps to accelerate the airflow around the object and thus dissipate heat and cool it down. Simultaneously, an airflow channel is provided on the fixing component, with the air outlet of the channel facing the accommodating space. For example, during the wireless charging of a mobile device using this stand, the airflow generated by the airflow generator can be guided to the screen surface of the mobile device through the airflow channel, thereby accelerating the airflow around the screen and further accelerating the overall heat dissipation of the mobile device. The reduced temperature of the mobile device, in turn, improves the wireless charging speed. Therefore, the wireless charging stand provided in this application embodiment can achieve rapid heat dissipation and cooling of the object to be charged, which is beneficial for improving the wireless charging speed.

[0006] In one possible implementation of this application, the air outlet is located on the surface of the fixing component adjacent to the accommodating space, and along the thickness direction of the base, the air outlet is located on the fixing component at a position away from the base.

[0007] In one possible implementation of this application, the fixing component includes two clamping members, each of which includes a connecting portion and a clamping portion. At least one clamping member is slidably disposed on the base via the connecting portion. The connecting portions of the two clamping members correspond to the airflow generator. The clamping portions of the two clamping members are distributed on opposite sides of the accommodating space. An airflow channel passes through the connecting portion and the clamping portion on the same clamping member, and the air outlet is located on the surface of the clamping portion facing the accommodating space.

[0008] In one possible implementation of this application, the distance between the air outlet on the clamping part and the surface of the base facing the accommodating space along the thickness direction of the base is greater than or equal to the thickness of the object to be charged.

[0009] In one possible implementation of this application, the clamping member further includes a protective portion extending from the clamping portion. Along the thickness direction of the base, the protective portion is located on the side of the clamping portion away from the connecting portion, and the protective portion extends from the clamping portion toward the accommodating space. The airflow channel sequentially passes through the connecting portion, the clamping portion and the protective portion on the same clamping member, and along the thickness direction of the base, the air outlet on the protective portion faces the accommodating space.

[0010] In one possible implementation of this application, the airflow generator is located inside the accommodating cavity, and the air inlet of the airflow channel is located on the connecting part, with the air inlet located inside the accommodating cavity.

[0011] In one possible implementation of this application, the wireless charging bracket further includes a linkage component. Both clamping components are slidably disposed on the base via connecting portions. Each of the two connecting portions has a linkage portion that matches the linkage component, and both linkage portions are connected to the linkage component. Under the action of the linkage component, the two clamping components can synchronously move closer to each other or synchronously move away from each other.

[0012] In one possible implementation of this application, the linkage includes a gear, and the linkage part includes a rack that matches the gear.

[0013] In one possible implementation of this application, the wireless charging bracket further includes a driving member disposed within the accommodating cavity. The driving member is connected to the linkage member via a transmission connection, and the driving member is used to drive the linkage member to move relative to the base.

[0014] In one possible implementation of this application, the wireless charging holder further includes a detection element, which is electrically connected to the drive element and the airflow generator via a controller. When the object to be charged is placed in the accommodating space, the detection element is triggered by the object to be charged and can generate an electrical signal to control the operating state of the drive element and / or the airflow generator.

[0015] In one possible implementation of this application, the clamping member further includes a supporting portion located at one end of the clamping portion, and the supporting portions on the two clamping members extend close to each other.

[0016] In one possible implementation of this application, the fixing component further includes a support member. Along the clamping direction of the vertical clamping member, the support member is disposed on the base near one end of the clamping member. The base, the support member, and the two clamping parts enclose and form an accommodating space. The support member has an airflow channel that passes through the support member, and the air outlet is located on the surface of the support member facing the accommodating space.

[0017] In one possible implementation of this application, the control element is electrically connected to the airflow generator and is used to control the flow rate of the airflow generated by the airflow generator. Attached Figure Description

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0031] With the development of technology, smartphones have become more than just communication tools, serving multiple functions such as entertainment, work, and study. However, the resulting high power consumption has made smartphone overheating a problem that must be addressed. For example, when using a wireless charging stand to charge a smartphone, the smartphone's temperature rises as the charging time increases.

[0032] In related technologies, wireless charging stands incorporate cooling pads or fans. When a smartphone is placed on such a stand, the cooling pad or fan can dissipate heat from the back of the smartphone, lowering its temperature. However, this effect is less effective for smartphones with external cases. During charging, heat from inside the smartphone is transferred to the screen, causing its temperature to rise. While methods like blowing air onto the back of the smartphone can reduce its temperature to some extent, the limited surface area available for heat dissipation results in poor overall heat dissipation, thus affecting the efficiency of wireless charging.

[0033] This application provides a wireless charging stand that can quickly dissipate heat and cool the object being charged, thereby increasing the speed of wireless charging. For ease of description and explanation, the following uses a smartphone as an example to illustrate the wireless charging stand provided in this application. However, this does not limit the wireless charging stand to charging only mobile phones. The wireless charging stand provided in this application can also charge electronic devices such as smartwatches and tablets that use wireless charging.

[0034] Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 Schematic diagram of the wireless charging stand provided in this application Figure 1 , Figure 2 This is a cross-sectional view of the wireless charging stand provided in this application. Figure 3 This is an exploded structural diagram of the wireless charging stand provided in this application. The wireless charging stand provided in this embodiment includes: a base 1, a wireless charging component 2, an airflow generator 3, and a fixing component 4. The base 1 has a receiving cavity; the wireless charging component 2 is disposed within the receiving cavity; the airflow generator 3 is disposed on the base 1; the fixing component 4 is disposed on the base 1, and a receiving space 7 for accommodating the object to be charged 9 is formed between the fixing component 4 and the base 1. The fixing component 4 has an airflow channel 41, with the air outlet 411 facing the receiving space 7. The airflow generated by the airflow generator 3 flows through the airflow channel 41 and from the air outlet 411 to the receiving space 7.

[0035] In this embodiment, the base 1 is used to support and install other components in the wireless charging bracket, and the wireless charging bracket can be placed on a table or fixed to the dashboard of a vehicle through the base 1.

[0036] For example, such as Figure 3 As shown, the base 1 can be configured to include a matching box 11 and a cover 12. A groove can be formed in the box 11, and the cover 12 can be fitted onto the opening of the box 11 to form a base 1 with a receiving cavity. A bracket for supporting and fixing the wireless charging bracket can be provided at the bottom of the box 11, so that the wireless charging bracket can be fixed to the dashboard by the bracket.

[0037] In this embodiment, the wireless charging component 2 includes one or more charging coils, which can be made of copper wire. The charging coils can transfer energy through the principle of electromagnetic induction to charge the mobile device placed on the wireless charging bracket. For example, the wireless charging component 2 can be fixed in the accommodating cavity of the base 1 and placed close to the cover 12 to reduce the distance between the wireless charging component 2 and the mobile device.

[0038] In this embodiment, the airflow generator 3 can generate a high-velocity airflow. For example, the airflow generator 3 can be an axial fan, a centrifugal fan, or a plasma fan. The airflow generator 3 can be fixed outside the base 1 or fixed inside the accommodating cavity.

[0039] In this embodiment, the fixing component 4 can guide the flow of air so that the airflow generated by the airflow generator 3 flows towards the device to be charged. For example, the fixing component 4 can be provided on the base 1, and a portion of the fixing component 4 can extend along the thickness direction Z of the base 1. For example, if the fixing component 4 extends from opposite sides of the base 1 along the thickness direction Z of the base 1, an open accommodating space 7 can be formed by the fixing component 4 and the base 1. The size and shape of the accommodating space 7 match the mobile device to be charged. The mobile device 9, which is to be charged, can be placed in the accommodating space 7.

[0040] For example, such as Figure 1 and Figure 2 As shown, an airflow channel 41 can be provided within the fixed assembly 4, and the air outlet 411 of the airflow channel 41 is located on the portion of the fixed assembly 4 facing the accommodating space 7. The other end of the airflow channel 41 can be aligned with the airflow generator 3. When the airflow generator 3 generates airflow, the airflow can enter the airflow channel 41. Guided and restricted by the airflow channel 41, the airflow flows through the airflow channel 41 and is blown from the air outlet 411 to the accommodating space 7.

[0041] The wireless charging stand provided in this embodiment has a fixing component 4 on the base 1, which together with the base 1 forms an open accommodating space 7. This provides a placement position for the object to be charged 9 and restricts its movement relative to the wireless charging stand. Furthermore, an airflow generator 3 is provided on the base 1 to generate airflow for the object to be charged 9, which helps to accelerate the airflow around the object and thus cool it down. Simultaneously, an airflow channel 41 is provided on the fixing component 4, with the air outlet 411 facing the accommodating space 7. For example, when wirelessly charging a mobile device (object to be charged 9) using this wireless charging stand, the airflow generated by the airflow generator 3 can be guided to the screen surface of the mobile device through the airflow channel 41, thereby accelerating the airflow around the screen and thus accelerating the overall heat dissipation of the mobile device. The reduced temperature of the mobile device further improves the wireless charging speed. Therefore, the wireless charging stand provided in this embodiment can achieve rapid heat dissipation and cooling of the object to be charged 9, which is beneficial for improving the wireless charging speed.

[0042] In some possible embodiments of this application, such as Figure 2 As shown, the air outlet 411 is located on the surface of the fixing component 4 facing the accommodating space 7, and along the thickness direction Z of the base 1, the air outlet 411 is located on the fixing component 4 at a position away from the base 1.

[0043] In this embodiment, by setting the position of the air outlet 411 of the airflow channel 41 on the fixing component 4, the airflow can be blown at least to the surface of the object to be charged 9 away from the base 1.

[0044] For example, the air outlet 411 of the airflow channel 41 can be positioned on the fixing component 4 at a location away from the base 1. For instance, while positioning the air outlet 411 on the surface of the fixing component 4 facing the receiving space 7, the air outlet 411 can be located at one end of the fixing component 4 away from the base 1 along the thickness direction Z of the base 1. In this way, when airflow passes through the air outlet 411 and blows onto the object to be charged 9, the airflow can be directed onto the surface of the object to be charged 9 away from the base 1.

[0045] In the above embodiment, since the air outlet 411 of the airflow channel 41 is located on the surface of the fixing component 4 adjacent to the accommodating space 7, the airflow can be directed towards the accommodating space 7. Furthermore, by positioning the air outlet 411 on the fixing component 4 away from the base 1, the airflow can be directed towards the surface of the device to be charged 9 away from the base 1. In this way, when the screen temperature of the device to be charged 9 rises, the screen of the device to be charged 9 can be rapidly cooled, which is beneficial to improving the overall cooling effect of the device to be charged 9.

[0046] In some possible embodiments of this application, such as Figure 1 and Figure 2 As shown, the fixing component 4 includes two clamping members 42, each of which includes a connecting portion 421 and a clamping portion 422. At least one clamping member 42 is slidably disposed on the base 1 through the connecting portion 421. The connecting portions 421 of the two clamping members 42 are corresponding to the airflow generator 3. The clamping portions 422 of the two clamping members 42 are distributed on opposite sides of the accommodating space 7. The airflow channel 41 passes through the connecting portion 421 and the clamping portion 422 on the same clamping member 42. The air outlet 411 is located on the surface of the clamping portion 422 facing the accommodating space 7.

[0047] In this embodiment, the fixing component 4 can be configured to include a clamping member 42 to clamp and fix the object to be charged 9, and the clamping member 42 can be used to set the airflow channel 41.

[0048] For example, two clamping members 42 can be provided on the base 1 and positioned on opposite sides of the base 1. For instance, one clamping member 42 can be fixed to one side of the base 1, while the other clamping member 42 can be movably positioned on the other side of the base 1. Alternatively, both clamping members 42 can be movably positioned on opposite sides of the base 1. This allows at least one clamping member 42 to move relative to the other, enabling the distance between the two clamping members 42 to decrease or increase, thereby facilitating the adjustment of the size of the receiving space 7 and securing the object to be charged 9 within the receiving space 7.

[0049] Another example, such as Figure 2 As shown, the clamping member 42 can be configured to include a connecting portion 421 and a clamping portion 422. For example, the clamping member 42 can be configured to have an approximately L-shaped structure, with one part of the L-shaped clamping member 42 serving as the connecting portion 421 and the other part serving as the clamping portion 422. The connecting portion 421 is connected to the base 1, and the clamping portion 422 extends along the thickness direction Z of the base 1. For example, a groove matching the connecting portion 421 can be provided on the base 1, allowing the connecting portion 421 of one clamping member 42 to be slidably disposed within the groove, or both connecting portions 421 of the clamping members 42 can be slidably disposed within the groove. A damping element can be provided between the connecting portion 421 and the groove on the base 1 to increase the friction between the connecting portion 421 and the groove. Thus, by manually pushing and pulling the clamping members 42, the clamping portions 422 of the two clamping members 42 can be moved closer or further apart to facilitate clamping and fixing the object to be charged 9.

[0050] Another example, such as Figure 2As shown, a through hole can be provided in the connecting part 421 and the clamping part 422, which can serve as an airflow channel 41. An air outlet 411 can be provided on the surface of the clamping part 422 facing the accommodating space 7. Simultaneously, the airflow generator 3 can be positioned opposite the connecting part 421. For example, if both the connecting part 421 and the airflow generator 3 are outside the base 1 (outside the accommodating cavity), a retractable connecting pipe can be provided between the airflow generator 3 and the connecting part 421 to guide the airflow generated by the airflow generator 3 to flow to the connecting part 421, allowing the airflow generated by the airflow generator 3 to flow into the airflow channel 41.

[0051] In the above embodiment, since the fixing component 4 includes two clamping members 42, and at least one clamping member 42 is slidably disposed on the base 1 through the connecting part 421, the object to be charged 9 can be clamped and fixed by moving the two clamping members 42 closer to each other or further away from each other. Furthermore, an airflow channel 41 is disposed on the clamping member 42, facilitating the flow of air generated by the airflow generator 3 through the airflow channel 41 on the clamping member 42 to the object to be charged 9.

[0052] In some possible embodiments of this application, such as Figure 2 As shown, along the thickness direction Z of the base 1, the distance between the air outlet 411 on the clamping part 422 and the surface of the base 1 facing the accommodating space 7 is greater than or equal to the thickness of the object to be charged 9.

[0053] In this embodiment, the position of the air outlet 411 on the clamping part 422 can be set according to the thickness of the object to be charged 9. For example, the object to be charged 9 is usually placed in the accommodating space 7 with its surface attached to the base 1 facing the accommodating space 7. After the object to be charged 9 is placed in the accommodating space 7, it is necessary to ensure that the object to be charged 9 does not completely block the air outlet 411 on the clamping part 422. Therefore, the distance between the air outlet 411 on the clamping part 422 and the surface of the base 1 facing the accommodating space 7 can be set to be greater than or equal to the thickness of the object to be charged 9.

[0054] For example, along the thickness direction Z of the base 1, the distance between the upper edge of the air outlet 411 on the clamping part 422 (the edge away from the base 1) and the surface of the base 1 facing the receiving space 7 can be at least greater than the thickness of the object to be charged 9. In this way, for some thicker objects to be charged 9, even if the object to be charged 9 partially blocks the air outlet 411 on the clamping part 422, the upper part of the air outlet 411 can still blow air onto the upper surface of the object to be charged 9.

[0055] In the above embodiment, since the distance between the air outlet 411 on the clamping part 422 and the surface of the base 1 facing the accommodating space 7 is greater than or equal to the thickness of the object to be charged 9, after the object to be charged 9 is placed into the accommodating space 7 and abuts against the base 1, and the clamping part 422 clamps the side of the object to be charged 9, the object to be charged 9 will not completely block the air outlet 411 on the clamping part 422, so that the airflow can be smoothly blown to the upper surface of the object to be charged 9 through the air outlet 411.

[0056] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the clamping member 42 also includes a protective portion 425 extending from the clamping portion 422. Along the thickness direction Z of the base 1, the protective portion 425 is located on the side of the clamping portion 422 away from the connecting portion 421, and the protective portion 425 extends from the clamping portion 422 toward the accommodating space 7. The airflow channel 41 passes through the connecting portion 421, the clamping portion 422 and the protective portion 425 on the same clamping member 42 in sequence. Along the thickness direction Z of the base 1, the air outlet 411 on the protective portion 425 faces the accommodating space 7.

[0057] In this embodiment, a protective portion 425 can be provided on the clamping member 42 to shield the object to be charged 9 located in the accommodating space 7. For example, Figure 2 As shown, the clamping member 42 can be configured with an approximately U-shaped cross-section, that is, along the thickness direction Z of the base 1, a connecting portion 421 and a protective portion 425 can be formed on both sides of the clamping portion 422, respectively. The connecting portion 421 and the protective portion 425 can be nearly parallel, and both the connecting portion 421 and the extension portion extend from the clamping portion 422 toward the receiving space 7. Furthermore, along the clamping direction X, the length of the protective portion 425 is shorter than the length of the connecting portion 421. In this way, when the two clamping members 42 are in a position far apart from each other, there is a gap between the two protective portions 425 that is larger than the width of the object to be charged 9, which facilitates the placement of the object to be charged 9 into the receiving space 7.

[0058] For example, an airflow channel 41 can be provided on the protective part 425. For instance, the airflow channel 41 can pass sequentially through the connecting part 421, the clamping part 422, and the protective part 425. The air outlet 411 on the protective part 425 can be provided on the surface of the protective part 425 facing the receiving space 7 along the thickness direction Z of the base 1. In this way, when the two clamping members 42 are in a position close to each other and the object to be charged 9 is clamped in the receiving space 7, the air outlets 411 on the two protective parts 425 face the upper surface of the object to be charged 9.

[0059] In the above embodiment, since the clamping member 42 also has a protective part 425, after the object to be charged 9 is placed into the receiving space 7, the protective part 425 can cover at least a portion of the upper surface of the object to be charged 9, which helps to reduce the risk of the object hitting the upper surface of the object to be charged 9. Furthermore, an air outlet 411 is provided on the protective part 425, which allows airflow to be guided by the air outlet 411 on the protective part 425 to blow from directly above the object to be charged 9 to the upper surface of the object to be charged 9, which helps to increase the contact time between the airflow and the upper surface of the object to be charged 9, thereby improving the efficiency of heat dissipation of the object to be charged 9.

[0060] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the airflow generator 3 is located inside the accommodating cavity, and the air inlet 412 of the airflow channel 41 is located on the connecting part 421, with the air inlet 412 located inside the accommodating cavity.

[0061] In this embodiment, the airflow generator 3 can be disposed within the accommodating cavity of the base 1. Correspondingly, at least a portion of the connecting portion 421 can be located within the accommodating cavity, that is, a sliding groove matching the connecting portion 421 can be provided on the base 1, and the sliding groove can extend into the accommodating cavity, allowing the connecting portion 421 to slide within the sliding groove. For example, the air inlet 412 of the airflow channel 41 can be disposed on one end of the connecting portion 421 near the airflow generator 3, or the air inlet 412 can be disposed on the side wall of the connecting portion 421 located within the accommodating cavity. Simultaneously, a vent can be provided at the bottom of the housing 11 of the base 1 to facilitate airflow into the accommodating cavity.

[0062] In the above embodiment, since the airflow generator 3 is placed in the accommodating cavity, and the connecting part 421 is located in the accommodating cavity, and the air inlet 412 of the airflow channel 41 is placed on the connecting part 421, it is convenient for the airflow generated by the airflow generator 3 to enter the airflow channel 41. The base 1 can provide protection for the airflow generator 3 and the air inlet 412, which helps to reduce the entry of debris into the airflow channel 41.

[0063] In some possible embodiments of this application, such as Figure 1 and Figure 3 As shown, the clamping member 42 also includes a supporting portion 424, which is located at one end of the clamping portion 422, and the supporting portions 424 on the two clamping members 42 extend close to each other.

[0064] In this embodiment, a support portion 424 capable of supporting the object to be charged 9 can be provided on the clamping member 42 to facilitate placing the object to be charged 9 within the accommodating space 7. For example, a support portion 424 can be provided on the clamping portion 422 of each clamping member 42, so that the clamping portion 422 and the support portion 424 on the same clamping member 42 form an approximately L-shaped structure, and the support portions 424 on the two clamping members 42 extend close to each other, that is, the support portions 424 on the two clamping members 42 both extend from the same end of the clamping portion 422 towards the center of the base 1. Along the clamping direction X, the sum of the lengths of the two support portions 424 can be less than the width of the object to be charged 9, and when the two clamping members 42 are in a position away from each other, there is a gap between the two support portions 424, and this gap is less than the width of the object to be charged 9. In this way, after the object to be charged 9 is placed into the receiving space 7, the supporting part 424 and the clamping part 422 can prevent the object to be charged 9 from falling out of the receiving space 7.

[0065] In the above embodiment, since a support portion 424 is also provided on the clamping member 42 and the support portion 424 is located at one end of the clamping portion 422, an approximately U-shaped open accommodating space 7 can be formed by the clamping portion 422 and the support portion 424 of the two clamping members 42. In this way, when the wireless charging bracket is placed at an angle, the support portion 424 can also restrict the movement of the object to be charged 9 relative to the accommodating space 7, which helps to reduce the risk of the object to be charged 9 falling off the accommodating space 7 and makes it easier to quickly place the object to be charged 9 into the accommodating space 7.

[0066] In some possible embodiments of this application, reference is made to Figure 4 , Figure 4 Schematic diagram of the wireless charging stand provided in this application Figure 2 The fixing component 4 also includes a support member 43. Along the clamping direction X of the vertical clamping member 42, the support member 43 is disposed on the base 1 at one end near the clamping member 42. The base 1, the support member 43 and the two clamping parts 422 enclose an open accommodating space 7. The support member 43 has an airflow channel that passes through the support member 43, and the air outlet is located on the surface of the support member 43 facing the accommodating space 7.

[0067] In this embodiment, a support member 43 can be provided on the wireless charging bracket to provide support and restraint for the object to be charged 9. For example, the support member 43 can be provided at the same end of the two clamping members 42, and at least a portion of the support member 43 can extend along the thickness direction Z of the base 1, and the support member 43 can extend to a position corresponding to the clamping portion 422, so that the support member 43 and the clamping portions 422 of the two clamping members 42 can jointly enclose and form an open accommodating space 7.

[0068] For example, an airflow channel can be provided on the support member 43, and the airflow channel can extend through the support member 43. For instance, the airflow channel can extend from the end of the support member 43 connected to the base 1 to the surface of the support member 43 facing the receiving space 7, so that the air outlet on the support member 43 faces the receiving space 7. And along the thickness direction Z of the base 1, the air outlet on the support member 43 can be located at the end of the support member 43 away from the base 1. In this way, the airflow blown from the support member 43 can reach the upper surface of the object to be charged 9.

[0069] Another example, such as Figure 4 As shown, an anti-slip element 8 can also be provided on the surface of the base 1 facing the accommodating space 7. For example, the protective element can be a rubber sheet or silicone sheet with grooves or protrusions. The anti-slip element 8 can increase the friction between the object to be charged 9 and the base 1, thereby reducing the sliding of the object to be charged 9 relative to the base 1.

[0070] In the above embodiment, since a support member 43 is provided on the base 1 near one end of the clamping member 42, the support member 43 can provide support and limit the charging object 9 placed between the two clamping members 42, which helps to reduce the risk of the charging object 9 slipping off the wireless charging bracket. Furthermore, the support member 43 is provided with an airflow channel and an air outlet, which allows the airflow generated by the airflow generator 3 to be blown onto the charging object 9 located in the accommodating space 7 from more directions.

[0071] In some possible embodiments of this application, such as Figure 3 As shown, the wireless charging bracket also includes a linkage component 5. Both clamping components 42 are slidably disposed on the base 1 through connecting parts 421. Both connecting parts 421 have linkage parts 423 that match the linkage component 5. Both linkage parts 423 are connected to the linkage component 5. Under the action of the linkage component 5, the two clamping components 42 can move closer to each other or move further away from each other synchronously.

[0072] In this embodiment, both clamping members 42 can be slidably disposed on the base 1. For example, the connecting portions 421 of the two clamping members 42 can both be configured as plate-like structures. Correspondingly, two sliding grooves matching the two plate-like connecting portions 421 are provided in the base 1, such as... Figure 2 As shown, along the thickness direction Z of the base 1, a portion of each of the two connecting parts 421 can be stacked in the receiving cavity so that the two clamping members 42 can move closer or further apart from each other on the base 1 along the clamping direction X through the connecting parts 421.

[0073] For example, a linkage member 5 can be provided within the accommodating cavity, and linkage parts 423 matching the linkage member 5 can be provided on the two connecting parts 421 respectively. For instance, the linkage part 423 can be configured as a guide post, and the linkage member 5 can be configured as a rod-shaped swing arm structure, with the swing arm rotatably disposed within the accommodating cavity, allowing it to swing in a plane perpendicular to the thickness direction Z of the base 1; simultaneously, a sliding groove matching the guide post is provided at each end of the swing arm, allowing the guide post to be positioned within the sliding groove. Thus, as... Figure 3 As shown, during the movement of one connecting part 421 away from the base 1 along the clamping direction X, it can drive the swing arm to swing, thereby driving the other clamping part 422 to also move away from the base 1, so that the two clamping parts 42 move away from each other synchronously. During the movement of one connecting part 421 towards the base 1 along the clamping direction X, it can drive the swing arm to swing, thereby driving the other clamping part 422 towards the base 1, so that the two clamping parts 42 move closer to each other synchronously.

[0074] In the above embodiment, since a linkage part 423 is provided on the connecting part 421 and the linkage parts 423 of the two clamping parts 42 are connected by the linkage part 5, the linkage of the two clamping parts 42 can be realized through the linkage part 5 and the linkage part 423. This allows the clamping parts 422 of the two clamping parts 42 to move closer or further away synchronously, thereby clamping and fixing the object to be charged 9 near the center of the base 1. This is beneficial for placing the object to be charged 9 in a charging position directly opposite the wireless charging component 2.

[0075] In some possible embodiments of this application, such as Figure 3 As shown, the linkage 5 includes a gear, and the linkage part 423 includes a rack that matches the gear.

[0076] In this embodiment, the linkage 5 can be a gear, and correspondingly, the linkage part 423 can be a rack that matches the gear. For example, the axial direction of the gear can be the same as the thickness direction Z of the base 1, so that the gear can be rotatably mounted in the accommodating cavity. An elongated notch can be provided on each connecting part 421, and the gear is located in two elongated notches. A rack can be provided on the side wall of the notch on each connecting part 421, with the two racks located on opposite sides of the gear. In this way, when the gear rotates, the tangent directions on both sides of the gear are opposite, which can drive the two racks to always move in opposite directions, thereby enabling the two clamping parts 42 to move closer or further away synchronously along the clamping direction X.

[0077] In the above embodiments, since the linkage 5 includes a gear and the linkage part 423 includes a rack that matches the gear, the linkage of the two clamping parts 42 can be achieved through the cooperation of the gear and the rack. Furthermore, the high cooperation accuracy of the gear and the rack is beneficial to improving the synchronization of the movement of the two clamping parts 42 and can improve the reliability of the linkage of the two clamping parts 42.

[0078] In some possible embodiments of this application, the wireless charging bracket further includes a driving member (not shown in the figure), which is disposed in the accommodating cavity and is connected to the linkage member 5 for transmission. The driving member is used to drive the linkage member 5 to move relative to the base 1.

[0079] In this embodiment, the driving component can drive the linkage 5 to rotate, thereby automatically moving the two clamping components 42 closer to or further apart. For example, when the linkage 5 is a gear, the driving component can be a servo electrode, a stepper electrode, or a regular motor, which can be fixed inside the accommodating cavity. The motor can be connected to the gear via a transmission mechanism, such as a reduction gear, a reduction pulley, or a belt, to ensure that the gear rotates at a suitable speed relative to the base 1. When the linkage 5 is a rocker arm, the driving component can be a linear motor, with the output shaft of the linear motor hinged to the rocker arm, allowing the linear motor to drive the rocker arm to swing.

[0080] In the above embodiments, since a driving member is provided for the linkage member 5, the linkage member 5 can be driven to move relative to the base 1 by the driving member, so that the two clamping members 42 can automatically move closer or further away, thereby realizing the automatic clamping or release of the object to be charged 9.

[0081] In some possible embodiments of this application, the wireless charging stand also includes a detection element (not shown in the figure), which is electrically connected to the drive element via a controller. The airflow generator 3 is electrically connected to the detection element via a controller. When the object to be charged 9 is placed in the accommodating space 7, the detection element is triggered by the object to be charged 9. The detection element can generate an electrical signal to control the working state of the drive element and / or the airflow generator 3.

[0082] In this embodiment, a detection element can be installed in the wireless charging holder to detect whether an object 9 to be charged is placed in the receiving space 7. For example, the detection element can be a radar, a contact switch, a photoelectric sensor, etc. The detection element can be placed on the surface of the base 1 near the receiving space 7, or its emitted sound and light signals can be transmitted to the receiving space 7. Thus, when the object 9 to be charged is placed in the receiving space 7, the detection element can be triggered to generate an electrical signal.

[0083] For example, the controller of the wireless charging stand can be electrically connected to the drive unit, the airflow generator, and the detection unit. For instance, the controller can be a microcontroller unit (MCU). After the detection unit generates an electrical signal, the MCU can control the drive unit to perform a driving action in response to the signal. The drive unit can then move the linkage 5 until the two clamping members 42 come close together and clamp the object 9 to be charged. The MCU can also control the airflow generator 3 to perform a blowing action in response to the electrical signal. The airflow generator 3 can then blow high-velocity gas into the airflow channel 41.

[0084] In the above embodiments, since the detection element is set on the wireless charging bracket at a position that can be triggered by the object to be charged 9, the working state of the drive element and / or airflow generator 3 can be controlled by the electrical signal generated by the detection element being triggered by the object to be charged 9, thereby realizing the automatic clamping and fixing of the object to be charged 9 by the clamping element 42.

[0085] In some possible embodiments of this application, the wireless charging stand also includes a control element (not shown in the figure), which is electrically connected to the airflow generator 3 and is used to control the flow rate of the airflow generated by the airflow generator 3.

[0086] In this embodiment, a control component can be installed in the wireless charging bracket. For example, the control component can be a touch button, a mechanical button, a rotary switch, etc. The control component can be electrically connected to the controller of the wireless charging device. By operating the control component, the magnitude of the current or voltage applied to the airflow generator 3 can be changed to control the flow rate of the airflow generated by the airflow generator 3.

[0087] In the above embodiments, since a control component electrically connected to the airflow generator 3 is provided in the wireless charging bracket, it is convenient to control the power of the airflow generator 3 so that the flow rate of the airflow generated by the airflow generator 3 matches the heat generated by the object to be charged 9, thereby controlling the temperature of the object to be charged 9 within a suitable temperature range.

[0088] Reference Figure 5 , Figure 5 This is a schematic diagram of the circuit structure of the wireless charging stand provided in this application. Figure 5 As shown, an external Type-C port can be provided on the wireless charging stand to facilitate electrical connection between the wireless charging stand and the power supply. A voltage conversion device can also be installed in the wireless charging stand, with the airflow generator 3 and the drive unit electrically connected to the voltage conversion device, which in turn is electrically connected to the MCU.

[0089] In this embodiment, when the Type-C port is powered on, the voltage conversion device begins to supply power to the MCU, wireless charging component 2, detection element, driving element, and airflow generator 3 in the wireless charging holder. At this time, if the user brings their smartphone close to the wireless charging holder, the detection element inside the wireless charging holder detects the presence of the smartphone and generates a corresponding electrical signal. After receiving this electrical signal, the MCU can send a command to the driving element. The driving element responds to the command and immediately begins to work, moving the clamping member 42 to clamp the smartphone. For example, the clamping member 42 can automatically clamp the smartphone within 3 seconds after it is placed in the receiving space 7, thus securely fixing the smartphone within the receiving space 7.

[0090] Simultaneously, after the Type-C port is powered on, the wireless charging component 2 enters standby mode, ready to charge the smartphone. When the foreign object detection (FOD) device or photoelectric sensor in the wireless charging component 2 detects the smartphone, the wireless charging component 2 begins charging the smartphone. During this process, the MCU can receive the status information of the wireless charging component 2 and can synchronously send commands to the airflow generator 3 to control the airflow generator 3 to turn on and off, so as to dissipate heat and cool the smartphone, keeping the smartphone's temperature within a suitable range.

[0091] Alternatively, after the Type-C port is powered on, the detection element is mistakenly triggered, causing the clamping elements 42 to move closer to each other. However, the FOD device or photoelectric sensor does not detect that the smartphone is being charged, so the MCU does not send a command to the airflow generator 3, keeping the airflow generator 3 in the off state.

[0092] For example, a release switch can be provided in the wireless charging holder. This release switch can be a touch button or a mechanical button, which controls the clamp 42 to open, releasing the clamped smartphone. An indicator light can also be provided in the wireless charging holder. For example, the indicator light can be a light-emitting diode (LED), and the indicator light can be electrically connected to the FOD device via a controller to indicate whether the smartphone is being wirelessly charged via the color of the indicator light.
