[0002] A wireless charging pad for mobile phones is a device that uses the principle of electromagnetic induction to wirelessly transmit electrical energy. It is mainly used to power smartphones that support wireless charging.

[0003] Most existing wireless charging pads for smartphones use the mainstream wireless charging method, employing a transmitting coil within the charging pad as the transmitter and a receiving coil on the smartphone as the receiver. The transmitting coil, connected to alternating current, generates an alternating magnetic field, which induces a current in the receiving coil and converts it into electrical energy. In other words, charging is achieved through magnetic field coupling.

[0037] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. 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 without inventive effort are within the scope of protection of this application.

[0038] The inventors, through analysis of existing technologies, discovered that the heat dissipation performance of current wireless charging pads for smartphones deteriorates after prolonged use, primarily due to the lack of dustproof design. Existing air-cooled heat dissipation channels are constantly exposed, easily accumulating dust or debris, obstructing airflow and reducing heat dissipation efficiency. Users must manually clean the accumulated dust or debris periodically, resulting in high maintenance costs. Furthermore, during high-power wireless charging (e.g., 15W and above), existing technologies are prone to overheating, leading to decreased charging efficiency and even triggering overheat protection. While existing technologies often employ passive cooling (such as heat sinks) or external fans, they lack intelligent control mechanisms, and the heat dissipation channels are easily clogged by dust, resulting in significant performance degradation over long-term use. For example, some wireless charging stands, while having built-in fans, do not link with the charging status, and the air vents lack dust protection, affecting heat dissipation. Furthermore, existing technologies typically only support wireless charging at a fixed angle or in a single screen orientation (such as portrait mode), failing to accommodate both landscape and portrait usage scenarios. Users must manually adjust the support components or change the stand's shape, which is cumbersome and prone to causing phone misalignment, leading to charging alignment failures. For instance, some folding stands achieve landscape support through extended arms, but lack vertical stability and require manual adjustment.

[0039] It should be noted that, in any embodiment of this application, the wireless charging device for smartphones provided in this application can also be applied to the support and heat dissipation of other types of electronic devices (such as smartwatches and tablets that can be wirelessly charged).

[0040] Referring to Figures 1-3, an embodiment of the present application shows a wireless charging device for a smartphone, including: a base 1 and a receiving seat 2 connected to the base 1;

[0041] The accommodating seat 2 includes a charging part 21, a supporting part 22, and a heat dissipation part 23; the supporting part 22 is disposed on the side of the accommodating seat 2 close to the base 1; the charging part 21 is disposed on the side of the accommodating seat 2 away from the base 1, and the charging part 21 is disposed on the same side of the accommodating seat 2 and the supporting part 22; the air outlet slot 231 of the heat dissipation part 23 is disposed between the charging part 21 and the supporting part 22, and the opening of the air outlet slot 231 faces the charging part 21;

[0042] The charging unit 21 includes an abutment block 211 and a push rod 212 that can be linked to the abutment block 211; the air outlet 231 is provided with a dustproof baffle 232 that can be movably covered by the opening of the air outlet 231.

[0043] When the mobile phone is placed in the receiving seat 2, the mobile phone presses the abutment block 211, causing the push rod 212 to push the dustproof baffle 232 and cause the dustproof baffle 232 to detach from the opening covering the air outlet 231.

[0044] In the embodiments of this application, addressing the issue that the heat dissipation performance of existing wireless charging docks for smartphones is affected by prolonged use, this application provides a solution for the automatic opening and resetting of the dustproof baffle 232 through a linkage structure of the abutment block 211 and the push rod 212. Specifically, this solution includes: a base 1 and a receiving seat 2 connected to the base 1; the receiving seat 2 includes: a charging part 21, a support part 22, and a heat dissipation part 23; the support part 22 is located on the side of the receiving seat 2 closest to the base 1; the charging part 21 is located on the side of the receiving seat 2 away from the base 1, and the charging part 21 is located on the side of the receiving seat 2 furthest from the base 1. The base 2 is on the same side as the support 22; the air outlet 231 of the heat dissipation part 23 is disposed between the charging part 21 and the support 22, and the opening of the air outlet 231 faces the charging part 21; the charging part 21 includes an abutment block 211 and a push rod 212 that can be linked to the abutment block 211; the air outlet 231 is provided with a dustproof baffle 232 that can be movably covered by the opening of the air outlet 231; when the mobile phone is placed on the base 2, the mobile phone presses the abutment block 211, causing the push rod 212 to push the dustproof baffle 232, and causing the dustproof baffle 232 to detach from the opening of the air outlet 231. Through the automatic opening and resetting design of the dustproof baffle 232, the air cooling channel is closed and opened, preventing dust from entering and ensuring the heat dissipation efficiency of the wireless charging base.

[0045] The following will further describe a wireless charging device for a smartphone in this exemplary embodiment.

[0046] It should be noted that the housing 2 and the base 1 can form a certain angle of inclination, so that when the mobile phone is placed on the housing 2, the mobile phone can lean against the housing 2 and the position of the mobile phone's receiving coil matches the position of the transmitting coil 216 of the charging unit 21.

[0047] A stepped structure can be formed between the charging part 21 and the support part 22. When the mobile phone is placed on the accommodating seat 2, the height difference of the stepped structure makes a certain heat dissipation gap for gas flow between the mobile phone and the charging part 21. The air outlet slot 231 is provided on the stepped structure and continuously releases airflow to the heat dissipation gap during operation to achieve heat dissipation.

[0048] When the phone is not placed in the housing 2, the extension of the abutment block 211 in the charging part 21 can be higher than the plane of the support part 22. When the phone is placed in the housing 2, the phone naturally pushes the abutment block 211 to retract towards the charging part 21. However, the amount of retraction is limited by the stepped structure. Therefore, the abutment end face of the abutment block 211 after maximum retraction is flush with the plane of the support part 22, so that the back of the phone retains a heat dissipation gap.

[0049] When the phone is not placed in the housing 2, the dustproof baffle 232 covers the opening of the air outlet 231, preventing dust from entering the air outlet 231, thus sealing the air-cooling channel. When the phone is placed in the housing 2, the dustproof baffle 232 detaches from covering the opening of the air outlet 231. At this time, if the air outlet 231 is in the air-venting state, dust is unlikely to enter the air outlet 231. Therefore, this embodiment of the application, through the automatic opening and resetting design of the dustproof baffle 232, can achieve the sealing of the air-cooling channel to prevent dust from entering when not charging; and automatically open during charging to ensure that heat dissipation efficiency is not affected, thereby achieving a balance between dust prevention and heat dissipation.

[0050] Referring to Figure 2, in one embodiment of this application, the charging unit 21 further includes: a rotating shaft 213 and a linkage member 214; both ends of the rotating shaft 213 are fixedly disposed in the inner cavity of the charging unit 21; one end of the linkage member 214 is connected to the abutment block 211, and the other end of the linkage member 214 is connected to the push rod 212, and the linkage member 214 is rotatably connected to the rotating shaft 213 along the axial direction of the rotating shaft 213.

[0051] In one embodiment of this application, the dustproof baffle 232 is an elastic element;

[0052] When the mobile phone is placed in the housing 2, the push rod 212 pushes the dustproof baffle 232 to elastically deform and detach from the opening of the air outlet slot 231.

[0053] It should be noted that the elastic dustproof baffle 232 can automatically open during charging and close when not charging to prevent dust from clogging the air-cooling channel, extend the service life of the device, and ensure heat dissipation. The lower end of the dustproof baffle 232 can be made of elastic metal material. Since the non-elastic deformation state of the dustproof baffle 232 covers the outside of the opening of the air outlet 231, when the mobile phone leaves the receiving seat 2, under the elastic reset action of the dustproof baffle 232, the dustproof baffle 232 pushes the push rod 212, and drives the linkage 214 and the abutment block 211 to push out and reset, thereby achieving the reset effect of all components, ready for the user's next use.

[0054] Referring to Figure 2, in one embodiment of this application, it further includes: a seat connecting block 3; the seat connecting block 3 is disposed at the connection between the base 1 and the receiving seat 2; the seat connecting block 3 is disposed on the side of the receiving seat 2 opposite to the support portion 22.

[0055] It should be noted that the seat connecting block 3 can serve as a strength support structure between the base 1 and the accommodating seat 2.

[0056] Referring to FIG6, in one embodiment of this application, the air inlet 233 of the heat dissipation part 23 is disposed on the side of the base connecting block 3 away from the air outlet groove 231.

[0057] It should be noted that the base connecting block 3 can provide a cooling channel for the heat dissipation part 23.

[0058] Referring to FIG2, in one embodiment of this application, the charging unit 21 further includes: a trigger switch 215; the trigger switch 215 is electrically connected to the cooling fan of the heat dissipation unit 23;

[0059] When the mobile phone is placed in the housing 2, the abutment block 211 presses the trigger switch 215 to drive the cooling fan to work.

[0060] It should be noted that when the mobile phone is not placed on the receiving seat 2, the trigger switch 215 is not triggered, and the cooling fan does not work. Through the linkage mechanism between the abutment block 211 and the trigger switch, the fan only starts when the mobile phone is placed on it. Combined with the synergistic effect of the heat dissipation gap and the air cooling channel, the temperature of the wireless charging area can be reduced by 15-20℃, effectively preventing overheating during high-power charging. The trigger switch 215 can also be triggered by the linkage member 214; the trigger switch 215 can also serve as a limiting structure for the linkage member 214 or the abutment member.

[0061] Referring to FIG4, in one embodiment of this application, the support portion 22 includes a support member 221;

[0062] When the mobile phone is placed in the receiving seat 2, the support member 221 abuts against one side of the mobile phone.

[0063] It should be noted that the support member 221 can be two cylindrical members. The shape of the support member 221 only needs to be designed to support the mobile phone.

[0064] Referring to FIG5, in one embodiment of this application, the support portion 22 further includes: a sliding frame 222 and an L-shaped limiting slide rail 223;

[0065] The support member 221 is movably disposed on the sliding frame 222 along the first direction of the L-shaped limiting slide rail 223; the sliding frame 222 is movably disposed along the second direction of the L-shaped limiting slide rail 223; the support member 221 is movably disposed along the first and second directions of the L-shaped limiting slide rail 223.

[0066] When the long side of the mobile phone abuts against the support member 221, the support member 221 is located at the end of the L-shaped limiting slide rail 223 in the first direction;

[0067] When the short side of the mobile phone abuts against the support member 221, the support member 221 is located at the end of the L-shaped limiting slide rail 223 in the second direction.

[0068] It should be noted that the first direction and the second direction of the L-shaped limiting slide rail 223 refer to the length directions of the slide rails on both sides of the bend of the L-shaped limiting slide rail 223, respectively. The first direction and the second direction of the L-shaped limiting slide rail 223 can be perpendicular to each other.

[0069] The support component 22 consists of a support member 221, an L-shaped limiting slide rail 223, and a sliding frame 222. The support member 221 is kept in a stable position by the elastic abutment member 2221, and the support height can be adjusted to match the horizontal or vertical screen state of the mobile phone. This ensures a precise match between the receiving coil of the mobile phone and the transmitting coil 216 of the charging dock, and avoids positional deviation caused by manual adjustment.

[0070] As an example, the support member 221 includes two components; the L-shaped limiting slide rail 223 also includes two components. When the two support members 221 are in their lowest position, they can support a phone in portrait mode; when the two support members 221 are in their other position, they can support a phone in landscape mode. To ensure that the two support members 221 can move synchronously, they are connected by the same sliding frame 222. The back of the sliding frame 222 has a longitudinally arranged groove 2222. The sliding frame 222 can only move vertically through the groove 2222, thereby driving the support member 221 to move vertically. At the same time, the support member 221 itself can move horizontally on the sliding frame 222 to match the movement requirements of any position of the L-shaped limiting slide rail 223.

[0071] Referring to FIG5, in one embodiment of this application, the sliding frame 222 includes an elastic abutment member 2221;

[0072] The elastic abutment 2221 is elastically connected to the support 221 at the end of the L-shaped limiting slide rail 223 in the first direction.

[0073] It should be noted that if the support member 221 causes the elastic abutment member 2221 to be in an elastic deformation state, the elastic abutment member 2221 will generate a spring force on the support member 221 toward the end of the L-shaped limiting slide rail 223 in the first direction. The elastic abutment member 2221 may include two members, and a spring may be provided between the two elastic abutment members 2221. The elastic abutment member 2221 abuts against the outer wall of the support member 221, with the purpose of always pushing the two abutment members outward. By applying such a spring force, the two support members 221 will not be easily moved to achieve a limiting position, especially in the landscape mode of the mobile phone, where the two support members 221 will not easily approach each other.

[0074] In one specific implementation, the user can push the support member 221 from the end of the L-shaped limiting slide rail 223 in the first direction to the bend, and then push it from the bend to the end of the L-shaped limiting slide rail 223 in the second direction.

[0075] In one specific implementation, the user can push the support member 221 from the end of the L-shaped limiting slide rail 223 in the second direction to the bend, and then push the support member 221 from the bend to the end of the L-shaped limiting slide rail 223 in the first direction through the elastic force of the elastic abutment member 2221.

[0076] Referring to Figures 2 and 6, in one embodiment of this application, the base 1 is provided with a power supply interface 11; the power supply interface 11 is electrically connected to the transmitting coil 216 of the charging unit 21.

[0077] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0078] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
