[0002] With the widespread application of intelligent cockpits in new energy vehicles, equipping vehicles with wireless charging panels in the center console for charging mobile phones is gradually becoming a basic standard feature of automobiles.

[0003] However, during daily driving, cars are constantly subjected to vibrations and impacts from road bumps, rapid acceleration, and sudden braking. Under these complex conditions, the chips on the wireless charging module PCBA board face severe stability challenges. Without proper protective measures, the chips can easily shift under frequent external forces. Once a chip becomes loose, the soldering structure between its pins and the PCBA board pads will be damaged, significantly reducing connection reliability. More worryingly, chip failure could potentially cause short circuits, overheating, or even catastrophic accidents such as vehicle fires, posing a serious threat to the lives of passengers.

Detailed Implementation

[0024] The following is based on the appendix Figure 1-5 Further explanation of this utility model:

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

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.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 As shown, the first embodiment of this utility model provides a vehicle-mounted wireless charging device based on the prior art, including: a lower housing assembly 100, a PCBA assembly 200, a coil assembly 300, and a filter cover assembly 400. The lower housing assembly 100 is provided with a mounting cavity, which extends along a first preset direction. The PCBA assembly 200 is embedded in the mounting cavity, and the coil assembly 300 is embedded in the mounting cavity. The coil assembly 300 is disposed on the upper part of the PCBA assembly 200. The filter cover assembly 400 is fastened to the top opening of the mounting cavity. The filter cover assembly 400 is used to seal the PCBA assembly 200 and the coil assembly 300 in the mounting cavity, and also to limit the movement of the PCBA assembly 200 and the coil assembly 300.

[0029] In this embodiment, the mounting cavity of the lower housing assembly 100 extends along a first preset direction, providing a specific mounting space for the PCBA assembly 200. This mounting method helps to stably embed the PCBA assembly 200 within the mounting cavity, reducing component shaking caused by vehicle vibration and thus reducing the possibility of chip displacement on the PCBA board. The coil assembly 300 is positioned above the PCBA assembly 200 and embedded within the mounting cavity. This layout fixes the relative positions of the components, forming a relatively stable overall structure. The stable component layout helps reduce mutual interference between components caused by vibration, further ensuring the stability of the chips on the PCBA board. The filter cover assembly 400 is fastened to the top opening of the mounting cavity, not only sealing the PCBA assembly 200 and the coil assembly 300 within the mounting cavity to prevent external dust, moisture, and other factors that may affect equipment performance from intruding, but also limiting the positioning of the PCBA assembly 200 and the coil assembly 300. By limiting the position of the chip, displacement on the PCBA board can be effectively prevented, ensuring a stable connection between the chip pins and the pads on the PCBA board. This reduces the safety risks caused by loose chips, avoids serious safety problems such as vehicle fires caused by chip failures, and protects the lives of drivers and passengers.

[0030] In this embodiment, as Figure 2 As shown, the lower housing assembly 100 includes: a lower housing body 106, a heat-conducting plate 105, at least two heat-conducting pillars 103 and at least two heat-conducting sheets 104. The lower housing body 106 is provided with an installation cavity. The heat-conducting plate 105 is disposed at the bottom of the installation cavity. The at least two heat-conducting pillars 103 are spaced apart and disposed on the heat-conducting plate 105. The at least two heat-conducting sheets 104 are spaced apart and disposed on the heat-conducting plate 105.

[0031] In this embodiment, the heat-conducting plate 105 is laid at the bottom of the mounting cavity of the lower housing body 106, which can quickly absorb the heat generated by the PCBA assembly 200 and the coil assembly 300 during operation. At least two heat-conducting pillars 103 and heat-conducting sheets 104 are spaced apart on the heat-conducting plate 105, which greatly increases the heat dissipation area and accelerates the conduction of heat to the outside. This design effectively avoids the performance degradation or failure of the chips on the PCBA board 204 due to overheating. Combined with the internal sealing protection of the filter cover assembly 400, it creates a stable temperature environment for the chips and reduces safety hazards such as loosening of chip pins and pads and equipment fire caused by high temperature. The heat-conducting pillars 103 and heat-conducting sheets 104 are spaced apart on the heat-conducting plate 105, which not only undertake the heat dissipation function, but also form a stable support structure in the mounting cavity. They cooperate with the lower housing body 106 to provide additional support points for the PCBA assembly 200 and the coil assembly 300. When the vehicle vibrates and is impacted, the structure can effectively disperse the external force and reduce the shaking of the components in the mounting cavity. Combined with the limiting design of the PCBA component 200 clearance groove 201 and the lower housing component 100, it further ensures the stability of the chip position on the PCBA board 204 and prevents chip displacement from causing failure.

[0032] Furthermore, the lower housing assembly 100 also includes at least four first connecting posts 101 and at least four second connecting posts 102, wherein the at least four first connecting posts 101 are respectively spaced apart within the lower housing body 106, and the at least four second connecting posts 102 are respectively spaced apart within the lower housing body 106; wherein the at least four first connecting posts 101 are used to connect to the filter cover assembly 400, and the at least four second connecting posts 102 are used to connect to the PCBA assembly 200.

[0033] The arrangement of at least four first connecting posts 101 and at least four second connecting posts 102 provides a reliable connection bridge between the various components of the equipment. The first connecting posts 101 are used to connect the filter cover assembly 400. Through a multi-point connection method, the filter cover assembly 400 is tightly integrated with the lower housing assembly 100. Under vehicle vibration environment, this effectively prevents relative displacement between the upper and lower components and ensures the stable operation of the equipment's sealing and limiting functions. The second connecting posts 102 are used to connect the PCBA assembly 200, firmly fixing the PCBA assembly within the lower housing body 106. This reduces the space for wobbling within the mounting cavity, lowers the risk of chip displacement due to PCBA assembly instability, and ensures the reliability of the connection between chip pins and pads.

[0034] In one exemplary embodiment, such as Figure 3As shown, the PCBA assembly 200 includes: a PCBA board 204, an electrical connection assembly 202, and a filter assembly 203. A clearance groove 201 is provided at the edge of the PCBA board 204. The clearance groove 201 is used to cooperate with the lower housing assembly 100 for limiting. The first electrical connection assembly 202 is disposed on the PCBA board 204. The electrical connection assembly 202 passes through the lower housing assembly 100 and is electrically connected to the vehicle end controller. The filter assembly 203 is disposed on the PCBA board 204 and is electrically connected to the filter cover assembly 400.

[0035] The clearance groove 201 provided at the edge of the PCBA board 204 cooperates with the lower housing assembly 100 to limit movement. This design creates a precise locking structure between the PCBA assembly 200 and the lower housing assembly 100. When vibrations and impacts occur during vehicle operation, the cooperation between the clearance groove 201 and the lower housing assembly 100 effectively restricts the movement of the PCBA board 204. Compared to simply relying on the mounting cavity for fixation, this adds additional limiting protection, further reducing the possibility of chip displacement on the PCBA board 204, securing the connection between chip pins and pads, and reducing safety hazards caused by loose chips.

[0036] Furthermore, such as Figure 4 As shown, the coil assembly 300 includes: a coil carrier plate 302, a first coil 301, a second coil 304, and a third coil 303. The coil carrier plate 302 is disposed on the PCBA assembly 200. The first coil 301 is disposed on the top of the coil carrier plate 302. The second coil 304 is disposed on the top of the coil carrier plate 302. The second coil 304 and the first coil 301 are arranged at intervals. The third coil 303 is connected to the second coil 304 and the first coil 301 respectively.

[0037] The first coil 301 and the second coil 304 are spaced apart on the top of the coil carrier 302 and interconnected via the third coil 303. This multi-coil combination design expands the effective sensing area of ​​wireless charging, improving charging efficiency and compatibility. The different coils work together to achieve more precise electromagnetic induction for different models and placement positions of mobile phones and other devices, reducing problems such as low charging efficiency or inability to charge due to charging position misalignment, thus meeting diverse user needs. Simultaneously, a reasonable coil layout helps to evenly distribute the magnetic field, reducing the risk of localized overheating caused by uneven magnetic fields, ensuring the stable operation of electronic components such as chips, and minimizing safety hazards caused by overheating.

[0038] In this embodiment, as Figure 5As shown, the filter cover assembly 400 includes: a filter cover body 402 and a filter connection component 403. The filter cover body 402 has at least four threaded holes 401 spaced apart. The at least four threaded holes 401 are used to connect with the lower housing assembly 100. The filter connection component 403 is electrically connected to the PCBA assembly 200.

[0039] The filter cover body 402 has at least four threaded holes 401 spaced apart, which can be tightly fixed to the first connecting post 101 in the lower housing assembly 100 by screws or other connectors. This multi-point threaded connection, compared to a single-point connection, can more evenly distribute the external forces caused by vibration and impact during vehicle operation, effectively preventing relative displacement between the filter cover assembly 400 and the lower housing assembly 100. This robust connection not only ensures the sealing effect of the mounting cavity, preventing external factors such as dust and moisture from intruding and affecting the performance of the PCBA assembly 200 and the coil assembly 300, but also provides reliable protection for the internal components, further ensuring the stability of the chips on the PCBA board 204 and reducing the risk of chip failure caused by external interference.

[0040] The filter connection component 403 is electrically connected to the PCBA assembly 200, effectively filtering electromagnetic interference generated by the PCBA assembly 200. Combined with the electrical connection design between the filter component 203 and the filter cover assembly 400 in the PCBA assembly 200, a dual filtering mechanism is formed, creating a favorable electromagnetic environment for electronic components such as chips. Stable electrical connections reduce the impact of electromagnetic interference on chip operation, preventing data transmission errors and functional abnormalities caused by electromagnetic interference, improving the stability and reliability of chip operation, and thus reducing the probability of vehicle safety hazards caused by chip failure.

[0041] The threaded hole 401 simplifies the installation and removal of the filter cover assembly 400. During equipment production and assembly, workers can quickly secure the filter cover assembly 400 to the lower housing assembly 100 using the threaded connectors. Later maintenance or repairs also facilitate the disassembly of the filter cover assembly 400 for inspection, repair, or replacement of the internal PCBA assembly 200 and coil assembly 300. This design improves production efficiency, reduces maintenance costs, and enhances the practicality and maintainability of the vehicle-mounted wireless charging equipment.

[0042] The second embodiment of this utility model provides a vehicle based on the first embodiment, including an in-vehicle wireless charging device, wherein the in-vehicle wireless charging device is the aforementioned in-vehicle wireless charging device.

[0043] Although embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
