Description

Technical Field

[0001] This utility model relates to the field of vehicle wireless charging technology, and in particular to a vehicle wireless charging device with high heat dissipation performance. Background Technology

[0002] With the continuous advancement of technology, smartphones and other mobile devices have become indispensable tools in people's lives. However, battery life remains a key concern for users. In in-vehicle scenarios, drivers require convenient, safe, and efficient charging methods while driving. Traditional wired chargers present numerous inconveniences, such as tangled cables, damaged interfaces, and cumbersome plugging and unplugging, affecting both the driving experience and potential safety hazards. Against this backdrop, in-vehicle wireless charging technology has emerged. In-vehicle wireless chargers primarily utilize the principle of electromagnetic induction to achieve contactless power transfer to mobile devices while the vehicle is in motion.

[0003] In existing technologies, a heat dissipation module (such as a heat sink) is often added under the wireless charging module for heat dissipation, but this cannot effectively solve the problem of overheating during mobile device charging. In addition, there are existing technologies with specific solutions for mobile device heat dissipation. For example, vents are created on the front of the charging panel, using a fan to ventilate and dissipate heat from the mobile device. However, this approach also has some problems: if the fan is placed above the panel, it occupies interior space and is unsightly; if the fan is embedded below the panel, when the phone is placed on the charging panel, at least part of the vents will inevitably be blocked, reducing airflow and resulting in poor phone heat dissipation; furthermore, fan cooling cannot simultaneously address the overheating issue of the wireless charging module, thus the overall heat dissipation effect is poor.

[0004] Therefore, designing an in-vehicle charging device that can simultaneously address the heat dissipation needs of both mobile devices and wireless charging modules is of significant value. Utility Model Content

[0005] In order to overcome the technical problem that the heat dissipation schemes in the above-mentioned vehicle charging technologies are difficult to balance the heat generation of mobile devices and wireless charging modules, this utility model provides a vehicle wireless charging device with high heat dissipation performance.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A vehicle-mounted wireless charging device with high heat dissipation performance, comprising:

[0008] support;

[0009] A heat-conducting component and a heat-conducting cover are provided. The heat-conducting component is located above the bracket, and the heat-conducting cover is located above the heat-conducting component and is fitted to the heat-conducting component. A wireless charging module is provided between the heat-conducting cover and the heat-conducting component. The top of the heat-conducting cover is used to place the device to be charged.

[0010] A heat sink, which is connected to the bottom side of the heat-conducting component;

[0011] The heat-conducting cover and the heat-conducting component are combined to form a heat-conducting channel, which is used to conduct the heat generated by the device to be charged and the wireless charging module to the heat sink.

[0012] In the above technical solution, the heat-conducting cover and heat-conducting components combine to form a heat-conducting channel. The heat-conducting cover, as part of the heat-conducting channel, not only conducts heat but also allows for direct placement of the mobile device to be charged (including but not limited to mobile phones) on its upper side, providing both anti-slip and protective functions, thus facilitating the placement and protection of the phone. The heat-conducting components, also part of the heat-conducting channel, not only conduct heat but also support the heat-conducting cover and, consequently, the mobile device on it, as well as the magnetic coil for accommodating the wireless charging module. This eliminates the need for additional support or accommodating structures, allowing for a rational and compact layout of all components, improving space utilization and overall performance stability. Therefore, this structural design addresses the heat generation issues of both the mobile device and the wireless charging module, resulting in excellent overall heat dissipation.

[0013] As a preferred embodiment, the heat-conducting component includes a support portion and a connecting portion connected to each other. The support portion is located above the bracket, and the heat-conducting cover is located above the support portion and is fitted to the support portion and the connecting portion. A wireless charging module is provided between the heat-conducting cover and the support portion, and the heat sink is connected to the bottom side of the connecting portion.

[0014] In the above technical solution, the heat-conducting cover, the support part and the connecting part are connected and combined in sequence to form a heat-conducting channel, which is used to conduct the heat generated by the device to be charged and the wireless charging module to the heat sink.

[0015] As a preferred embodiment, the support portion and the connecting portion are an integral structure.

[0016] In the above technical solution, the integrated structural design of the support and the connecting part can eliminate the need for connecting parts (bolts, washers, clips, etc.) required by the traditional split structure, reduce the space occupied by redundant parts, further optimize the space utilization, and have better heat dissipation performance.

[0017] As a preferred embodiment, the support portion and the connecting portion are separate structures.

[0018] In the above technical solution, the separate structural design of the support and the connecting parts allows them to be manufactured using different materials and processes, optimizing performance for their respective functional requirements. Furthermore, the separate structural design can also optimize heat transfer efficiency by adjusting the connection (such as by adding thermally conductive silicone).

[0019] As a preferred embodiment, the heat-conducting component is an alloy structure, and the heat-conducting cover is made of heat-conducting silicone.

[0020] In the above technical solution, the heat-conducting component adopts an alloy structure. This alloy component, as the core architecture, not only provides excellent heat dissipation performance but also constructs a stable physical support system, accommodating and supporting the wireless charging module and the device to be charged. The heat-conducting cover is made of thermally conductive silicone, which, while possessing good thermal conductivity, also features low hardness and anti-slip properties. This prevents scratches on the device to be charged, and its high static friction coefficient further enhances its anti-slip effect, providing multiple layers of protection for the device.

[0021] As a preferred embodiment, the top side of the heat-conducting cover is provided with any one or more of an anti-slip surface, an anti-slip pad, or an anti-slip structure.

[0022] In the above technical solutions, the use of anti-slip surfaces, anti-slip pads, or anti-slip structures can effectively increase the friction between the heat-conducting cover and the contact surface of the charging device, further enhance the anti-slip performance of the heat-conducting cover, prevent the device from sliding during use, ensure the device is placed stably, reduce the risk of accidental drops, and improve safety.

[0023] As a preferred embodiment, the thickness of the heat-conducting cover is less than or equal to 1.2 mm, the Rockwell hardness of the upper surface of the heat-conducting cover is less than 80H, and the static friction coefficient of the upper surface of the heat-conducting cover is greater than or equal to 1.0.

[0024] In the above technical solution, since the magnetic attraction of the magnetic structure in the wireless charging module to the phone decreases sharply with the increase of the thickness of the heat-conducting cover, the thickness design of the heat-conducting cover allows the magnetic field generated by the coil module in the wireless charging module to penetrate the heat-conducting cover more effectively. This ensures a stable attraction between the phone and the magnetic coil, preventing the phone from easily falling off during use and further improving safety and reliability. The Rockwell hardness design of the upper surface of the heat-conducting cover aims to prevent scratching the device being charged. The lower hardness makes the heat-conducting cover more gentle when in contact with the device, preventing scratches or wear on its surface and effectively reducing damage to the device. The static friction coefficient design of the upper surface of the heat-conducting cover aims to provide good anti-slip function. A high static friction coefficient means that a large frictional force can be generated between the heat-conducting cover and the device being charged, preventing the device from sliding on the heat-conducting cover. This is especially important in use on inclined surfaces, effectively preventing the device from falling due to slippage and improving stability and safety during use.

[0025] As a preferred embodiment, the high heat dissipation performance vehicle wireless charging device further includes a thermally conductive connector, which is disposed between the thermally conductive component and the thermally conductive cover to connect the thermally conductive component and the thermally conductive cover.

[0026] In the above technical solution, on the one hand, the thermally conductive connector plays a crucial role in heat conduction between the thermally conductive component and the thermally conductive cover, ensuring that heat is rapidly transferred from the thermally conductive cover to the thermally conductive component, thereby improving the overall heat dissipation efficiency of the device. On the other hand, the thermally conductive connector can firmly adhere to the surfaces of the thermally conductive component and the thermally conductive cover. This adhesion not only ensures the reliability of the connection but also prevents the thermally conductive connector from shifting or falling off during use. Therefore, the use of a thermally conductive connector design not only further improves the heat dissipation performance between the thermally conductive component and the thermally conductive cover but also ensures a stable connection between the aforementioned components, enhancing the reliability and performance of the overall structure.

[0027] As a preferred embodiment, the high heat dissipation performance vehicle-mounted wireless charging device further includes a thermally conductive connector, which is disposed between the thermally conductive component and the heat sink to connect the thermally conductive component and the heat sink.

[0028] In the above technical solution, on the one hand, the thermally conductive connector plays a crucial role in heat conduction between the thermally conductive component and the heat sink, ensuring that heat is rapidly transferred from the thermally conductive component to the heat sink, thereby improving the overall heat dissipation efficiency of the device. On the other hand, the thermally conductive connector can firmly adhere to the contact surface between the thermally conductive component and the heat sink, ensuring the reliability of the connection and preventing the thermally conductive connector from shifting or falling off during use. Therefore, the design using thermally conductive connectors not only further improves the heat dissipation performance between the thermally conductive component and the heat sink, but also ensures a stable connection between the above components, improving the reliability and performance of the overall structure.

[0029] As a preferred embodiment, the thermally conductive connector is a thermally conductive gel.

[0030] In the above technical solution, using thermally conductive gel as a thermally conductive connector can fully utilize the high thermal conductivity, good flexibility, and compressibility of the thermally conductive gel. It can fill tiny gaps and uneven surfaces between the thermally conductive component and the thermally conductive cover, and between the thermally conductive component and the heat sink, thereby reducing thermal resistance, enhancing heat conduction, and ensuring connection stability. Furthermore, the thermally conductive gel has good adhesion, high-temperature resistance, and aging resistance, enabling it to work reliably in automotive environments for extended periods without losing its thermal conductivity due to temperature changes or prolonged use.

[0031] As a preferred embodiment, the high heat dissipation performance vehicle wireless charging device further includes an upper cover and a lower cover, which are detachably mounted on the upper and lower sides of the bracket, respectively. A receiving space is formed between the bracket, the upper cover, and the lower cover, which is used to accommodate all or at least part of the structure of the heat-conducting component, the heat-conducting cover, and the radiator.

[0032] In the above technical solution, the detachable installation method between the upper cover and the bracket, and between the lower cover and the bracket, makes the structure of the entire vehicle wireless charging device more modular. This not only facilitates assembly and debugging during the production process, but also makes subsequent maintenance and component replacement more convenient. After installation, the upper cover, lower cover, and bracket together form a stable outer shell structure, which can effectively protect the internal heat-conducting components, heat-conducting cover, and heat sink.

[0033] In summary, the in-vehicle wireless charging device with high heat dissipation performance provided by this utility model has at least the following technical advantages compared with the prior art:

[0034] 1) The heat-conducting cover, support and connecting part of this utility model are combined to form a heat-conducting channel. The heat generated by the mobile device placed on the heat-conducting cover can be conducted to the heat sink through the heat-conducting channel of heat-conducting cover-support-connecting part. The heat generated by the wireless charging module set between the heat-conducting cover and the support can be conducted to the heat sink through the heat-conducting channel of support-connecting part. The above structural design takes into account the heat generation problem of mobile devices and wireless charging modules, and the overall heat dissipation effect is good.

[0035] 2) The heat-conducting component includes a support part. While serving as part of the heat-conducting channel, it also supports the mobile device to be charged on the heat-conducting cover and the magnetic coil of the wireless charging module. No additional support or housing structure is required, which allows the components to be laid out reasonably and arranged compactly, optimizing the internal structure of the entire vehicle wireless charger, improving space utilization and overall performance stability.

[0036] 3) The heat-conducting cover is located above the support. While serving as part of the heat-conducting channel structure, it also allows the mobile device to be charged to be placed directly on its upper side. It has both anti-slip and protective functions, thus facilitating the placement and protection of the mobile phone. Attached Figure Description

[0043] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0046] See Figures 1-4 As shown, in the technical solution of this utility model, the vehicle-mounted wireless charging device with high heat dissipation performance includes a bracket 1, a heat-conducting component 2, and a heat-conducting cover 3. The heat-conducting component 2 is disposed above the bracket 1; the heat-conducting cover 3 is disposed above the heat-conducting component 2 and is fitted to the heat-conducting component 2. A wireless charging module 5 is provided between the heat-conducting cover 3 and the heat-conducting component 2, and the top of the heat-conducting cover 3 is used to place the device to be charged.

[0047] Specifically, the heat-conducting component 2 supports the heat-conducting cover 3, thereby supporting the mobile device to be charged on the heat-conducting cover 3. Furthermore, the space between the heat-conducting component 2 and the heat-conducting cover 3 can accommodate the wireless charging module 5, eliminating the need for additional support or housing structures. This allows for a rational and compact layout of all components, optimizing the internal structure of the entire vehicle wireless charger, improving space utilization and overall performance stability. The heat-conducting cover 3 is positioned above the heat-conducting component 2, and its upper surface can directly hold the device to be charged, providing both anti-slip and protective functions, thus facilitating the placement and protection of the mobile phone.

[0048] It is worth mentioning that the device to be charged or the mobile device to be charged described in this utility model includes, but is not limited to, mobile phones. Furthermore, the wireless charging module 5 described in this utility model includes, but is not limited to, structures such as magnetic structures and charging coil modules.

[0049] The high-heat-dissipation-performance in-vehicle wireless charging device also includes a radiator 4, which is connected to the bottom side of the heat-conducting component 2. The heat-conducting cover 3 and the heat-conducting component 2 combine to form a heat-conducting channel, used to conduct heat generated by the device to be charged and the wireless charging module 5 to the radiator 4. Specifically, heat generated by the mobile device placed on the heat-conducting cover 3 and the wireless charging module 5 positioned between the heat-conducting cover 3 and the support 21 can be conducted to the radiator 4 through the aforementioned heat-conducting channel. Thus, the heat-conducting cover 3 and the heat-conducting component 2 not only serve to accommodate and support the device but also provide heat conduction. Furthermore, the above structural design addresses the heat generation issues of both the device to be charged and the wireless charging module 5, resulting in excellent overall heat dissipation.

[0050] Example 1

[0051] In the first preferred embodiment of this utility model, a specific structural design scheme for the heat-conducting component 2 is provided.

[0052] See Figures 1-4 As shown, in the technical solution of this embodiment, the heat-conducting component 2 includes a support part 21 and a connecting part 22 that are connected to each other. The support part 21 is located above the bracket 1, and the heat-conducting cover 3 is located above the support part 21 and is fitted to the support part 21 and the connecting part 22. A wireless charging module 5 is provided between the heat-conducting cover 3 and the support part 21, and the heat sink 4 is connected to the bottom side of the connecting part 22.

[0053] Specifically, the support portion 21 supports the heat-conducting cover 3, thereby supporting the mobile device to be charged on the heat-conducting cover 3. Furthermore, the support portion 21 can accommodate the wireless charging module 5, eliminating the need for additional support or housing structures. This allows for a reasonable and compact layout of all components, optimizing the internal structure of the entire vehicle wireless charger, improving space utilization and overall performance stability. The heat-conducting cover 3 is located above the support portion 21, and its upper side can directly hold the device to be charged, providing both anti-slip and protective functions, thus facilitating the placement and protection of the mobile phone.

[0054] More specifically, the heat-conducting cover 3, the support 21, and the connecting part 22 combine to form a heat-conducting channel, which is used to conduct the heat generated by the device to be charged and the wireless charging module 5 to the heat sink 4. Specifically, the heat generated by the mobile device placed on the heat-conducting cover 3 can be conducted to the heat sink 4 through the heat-conducting channel of "heat-conducting cover 3-support 21-connecting part 22" or "heat-conducting cover 3-connecting part 22". The heat generated by the wireless charging module 5, which is located between the heat-conducting cover 3 and the support 21, can be conducted to the heat sink 4 through the heat-conducting channel of "support 21-connecting part 22". Finally, the heat sink 4 completes the heat dissipation, thus addressing the heat generation issues of both the device to be charged and the wireless charging module 5, resulting in good overall heat dissipation.

[0055] In one alternative embodiment, the support 21 and the connecting part 22 are an integral structure. This integral structure design can eliminate the need for connectors required by traditional split structures, reduce the space occupied by redundant components, further optimize space utilization, and have better heat dissipation performance.

[0056] In another alternative embodiment, the support 21 and the connecting part 22 are separate structures. This separate structure design allows the support 21 and the connecting part 22 to be manufactured using different materials and processes, optimize performance for their respective functional requirements, and optimize heat conduction efficiency by adjusting the connection (such as adding thermally conductive silicone).

[0057] Both of the above structural design approaches have their advantages, and the design should be tailored to different specific needs. For example, for applications that prioritize compactness, high heat dissipation efficiency, and reliability, an integrated structural design is more suitable. Conversely, for applications requiring high flexibility, ease of repair and maintenance, a split structural design is more advantageous.

[0058] Based on the two optional solutions mentioned above, the heat conduction component 2 preferably adopts an alloy structure. The alloy heat conduction component 2 has excellent structural performance, which not only provides excellent heat dissipation performance, but also builds a stable physical support system, which plays a stable role in housing and supporting the wireless charging module 5 and the device to be charged.

[0059] Based on the two options mentioned above, the thermally conductive cover 3 is preferably made of thermally conductive silicone, which has good thermal conductivity while also having low hardness and anti-slip properties. This can prevent the device to be charged from being scratched, and with its large static friction coefficient, it can also provide anti-slip effect, thus providing multiple protections for the device to be charged.

[0060] In another optional embodiment, the top side of the heat-conducting cover 3 is provided with any one or more of an anti-slip surface, an anti-slip pad, or an anti-slip structure. Specifically, adopting an anti-slip surface, an anti-slip pad, or an anti-slip structure design can effectively increase the friction between the heat-conducting cover 3 and the contact surface of the charging device, further enhance the anti-slip performance of the heat-conducting cover 3, prevent the device from sliding during use, ensure the device is placed stably, and improve the safety of use.

[0061] More specifically, the anti-slip structure can be a strip-shaped protrusion, a columnar protrusion, or other structures that can increase the static friction coefficient of the upper surface of the anti-slip structure formed on the top side of the heat-conducting cover 3.

[0062] It is worth mentioning that the anti-slip pad or anti-slip structure and the heat-conducting cover 3 can be a separate structure or a one-piece molding.

[0063] In another optional embodiment, since the magnetic attraction of the magnetic structure in the wireless charging module 5 to the mobile phone decreases sharply with the increase of the thickness of the heat-conducting cover 3, the thickness of the heat-conducting cover 3 is set to be less than or equal to 1.2 mm in this embodiment. This structural design allows the magnetic field generated by the coil module in the wireless charging module 5 to penetrate the heat-conducting cover 3 more effectively, thereby ensuring a stable attraction force between the device to be charged and the magnetic coil. This ensures that the mobile phone will not easily fall off during use, further improving the safety and reliability of use.

[0064] The upper surface of the heat-conducting cover 3 has a Rockwell hardness of less than 80H. The purpose of this lower hardness design is to avoid scratching the device to be charged. The lower hardness makes the heat-conducting cover 3 more gentle when in contact with the device to be charged, and will not cause scratches or wear on its surface, effectively reducing damage to the device to be charged.

[0065] The static friction coefficient of the upper surface of the heat-conducting cover 3 is greater than or equal to 1.0. The purpose of the high static friction coefficient is to give the heat-conducting cover 3 good anti-slip function. The high static friction coefficient means that the heat-conducting cover 3 and the device to be charged can generate a large friction force, thereby preventing the device to be charged from sliding on the heat-conducting cover 3. This is especially important in the use scenario of inclined surface, which can effectively prevent the device to be charged from falling due to sliding, and improve the stability and safety during use.

[0066] Example 2

[0067] In the first preferred embodiment of this utility model, a connection design scheme between various heat-conducting components is provided.

[0068] In an optional embodiment, the high-heat-dissipation-performance vehicle-mounted wireless charging device further includes a thermally conductive connector disposed between the thermally conductive component 2 and the thermally conductive cover 3, thereby connecting the two components together. In terms of thermal conductivity, the thermally conductive connector plays a crucial role in heat conduction between the thermally conductive component 2 and the thermally conductive cover 3, ensuring rapid heat transfer from the thermally conductive cover 3 to the thermally conductive component 2, thus improving the overall heat dissipation efficiency of the device. Structurally, the thermally conductive connector adheres firmly to the surfaces of the thermally conductive component 2 and the thermally conductive cover 3. This adhesion not only ensures the reliability of the connection but also prevents the connector from shifting or falling off during use. Therefore, the use of a thermally conductive connector not only further enhances the heat dissipation performance between the thermally conductive component 2 and the thermally conductive cover 3 but also ensures a stable connection between them, improving the overall structural reliability and performance.

[0069] In another optional embodiment, the high-heat-dissipation-performance vehicle-mounted wireless charging device further includes a thermally conductive connector disposed between the thermally conductive component 2 and the heat sink 4, thereby connecting the two components together. In terms of thermal conductivity, the thermally conductive connector plays a crucial role in heat conduction between the thermally conductive component 2 and the heat sink 4, ensuring rapid heat transfer from the thermally conductive component 2 to the heat sink 4, thus improving the overall heat dissipation efficiency of the device. Structurally, the thermally conductive connector can firmly adhere to the contact surface between the thermally conductive component 2 and the heat sink 4, ensuring reliable connection and preventing displacement or detachment during use. Therefore, the use of a thermally conductive connector not only further enhances the heat dissipation performance between the thermally conductive component 2 and the heat sink 4 but also ensures a stable connection between the components, improving the overall structural reliability and performance.

[0070] Based on the two options mentioned above, thermally conductive connectors preferably use thermally conductive gel. On one hand, the high thermal conductivity, good flexibility, and compressibility of the thermally conductive gel can be fully utilized to fill tiny gaps and uneven surfaces between the thermally conductive component 2 and the thermally conductive cover 3, and between the thermally conductive component 2 and the heat sink 4, thereby reducing thermal resistance, enhancing heat conduction, and ensuring connection stability. On the other hand, the good adhesion, high-temperature resistance, and aging resistance of the thermally conductive gel can be fully utilized, enabling it to work reliably for a long time in the automotive environment without losing its thermal conductivity due to temperature changes or long-term use.

[0071] Example 3

[0072] In the first preferred embodiment of this utility model, an overall structural design scheme for a vehicle-mounted wireless charging device with high heat dissipation performance is provided.

[0073] See Figure 3 As shown in the technical solution of this embodiment, the high heat dissipation performance vehicle-mounted wireless charging device also includes an upper cover 6 and a lower cover 7, which are detachably installed on the upper and lower sides of the bracket 1, respectively. The detachable installation method between the upper cover 6 and the bracket 1, and between the lower cover 7 and the bracket 1, makes the structure of the entire vehicle-mounted wireless charging device more modular. This not only facilitates assembly and debugging during the production process but also makes subsequent maintenance and component replacement more convenient. For example, when the heat-conducting component 2 or the radiator 4 needs cleaning, repair, or upgrading, the internal components can be easily accessed simply by removing the upper cover 6 or the lower cover 7, without disassembling the entire device.

[0074] Furthermore, after installation, the upper cover 6, the lower cover 7, and the bracket 1 together form a stable outer shell structure. The bracket 1, the upper cover 6, and the lower cover 7 form an accommodating space, which is used to accommodate all or at least part of the structure of the heat-conducting component 2, the heat-conducting cover 3, and the radiator 4, thereby effectively protecting the internal components and ensuring their reliable operation in various vehicle environments.

[0075] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
