Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted wireless charging technology, and in particular to a wireless charging device based on space optimization design. Background Technology

[0002] With the continuous development of smartphones, most phones now have wireless charging capabilities. As an important in-vehicle application scenario that supports this function, in-car magnetic wireless chargers are experiencing rapid growth due to their convenience and safety.

[0003] In the field of in-vehicle magnetic wireless chargers, traditional designs suffer from numerous problems. Common in-vehicle magnetic wireless chargers consist of a magnetic charging coil, PCBA, NFC, and a heat dissipation module, but the overall layout is not ideal (especially in dual- or multi-charging-zone wireless charging solutions), resulting in a large footprint, primarily in terms of vertical height. This affects the interior space layout and reduces the user experience. Furthermore, the height limits the charger's installation location, making it difficult to meet the space requirements of the vehicle interior and restricting the flexibility and versatility of wireless charging solutions. On the other hand, simply optimizing the structure by squeezing out space for other components, such as reducing the space for the heat dissipation module, leads to new technical problems such as poor heat dissipation.

[0004] Therefore, given the current trend of automotive companies prioritizing space optimization, designing a well-structured and compact in-vehicle wireless charger is of significant importance. Utility Model Content

[0005] To overcome the technical problems caused by the unreasonable spatial arrangement of the above-mentioned vehicle magnetic wireless charging technology, such as occupying a large amount of vehicle interior space and affecting the layout of the charger, this utility model provides a wireless charging device based on space optimization design.

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

[0007] A wireless charging device based on space optimization design includes a bracket, with a panel and a back cover on the upper and lower sides of the bracket, respectively. A receiving space is formed between the bracket, the panel, and the back cover. The receiving space includes a heat-conducting protrusion, a heat-conducting top cover, a heat dissipation device, and a circuit board. The panel has several first through holes, through which the heat-conducting protrusion and the heat-conducting top cover extend, with the heat-conducting top cover positioned above the heat-conducting protrusion. A wireless charging module is disposed between the heat-conducting top cover and the heat-conducting protrusion. The heat dissipation device is connected to the heat-conducting protrusion. The circuit board has a clearance, through which the heat dissipation device passes, so that the heat dissipation device and the circuit board are arranged side by side in the horizontal direction.

[0008] In the above technical solution, a housing space is formed by the bracket, panel, and rear cover. Optimizing the layout of each component within this space enables a highly integrated design for the wireless charging device. While ensuring wireless charging efficiency and heat dissipation efficiency, the vertical height is minimized, resulting in a more compact overall structure and saving interior space. The shape of the heat-conducting top cover matches the shape of the heat-conducting protrusion, achieving an integrated design that combines the three functions of housing the wireless charging module, supporting the device to be charged, and conducting heat to the heat source. This significantly reduces the use of other unnecessary structures, effectively lowering the overall height of the charging module and making the product more compact and lightweight. The clearance design of the circuit board allows the heat dissipation device and the circuit board to be arranged side-by-side in the horizontal direction, minimizing the space required in the vertical direction, reducing the height of the wireless charging module, improving space utilization, and ensuring a good heat transfer path between the heat dissipation device and the circuit board, avoiding reduced heat dissipation efficiency due to excessive distance or structural obstruction.

[0009] As a preferred embodiment, the heat dissipation device includes a heat dissipation body and heat sinks, the heat dissipation body is connected to the heat-conducting boss, and the heat sinks are spaced apart on the bottom side of the heat dissipation body.

[0010] In the above technical solution, the heat sink can significantly increase the contact area between the heat dissipation device and the surrounding air, thereby achieving more efficient heat exchange and improving heat dissipation efficiency. Furthermore, placing the heat sink on the bottom side of the heat dissipation body does not occupy excessive space in the vertical direction and does not affect the spatial arrangement of components such as circuit boards arranged alongside it.

[0011] As a preferred embodiment, the wireless charging device based on space optimization design further includes a cooling fan, wherein the cooling fan and the heat dissipation device are arranged side by side in the horizontal direction, and the cooling fan is adjacent to or attached to the circuit board; wherein the number of cooling fans is at least two, and each cooling fan can be controlled independently.

[0012] In the above technical solution, the cooling fan actively drives the surrounding airflow when it is working, accelerating the dissipation of heat around the heat sink and the heat dissipation body, thus improving heat dissipation efficiency. Furthermore, the cooling fan can directly act on the circuit board to dissipate heat, thereby maintaining the stable operation of the electronic components on the circuit board and preventing performance degradation or damage to the components due to overheating.

[0013] As a preferred embodiment, the rear cover is provided with a second through hole, and the cooling fan includes an air inlet and an air outlet. One of the air inlet and the air outlet is provided corresponding to the second through hole, and the other is provided corresponding to the heat sink.

[0014] In the above technical solution, the cooling fan, heat sink and the second through hole of the back cover can be organically combined to form a complete heat dissipation system. The parts cooperate and work together to improve the reliability and efficiency of the entire heat dissipation system, and at the same time make the layout of the heat dissipation system more reasonable.

[0015] As a preferred embodiment, the top side of the heat-conducting boss is provided with a receiving groove, and the wireless charging module is disposed in the receiving groove.

[0016] In the above technical solution, the wireless charging module is placed within the receiving groove of the heat-conducting boss, thus eliminating the need for additional support or housing structures. This allows for a reasonable and compact layout of the components, reducing the risk of module displacement due to vibration or external forces during use and improving stability and reliability. Furthermore, because the wireless charging module is located within the receiving groove of the heat-conducting boss, heat can be more directly conducted to the boss. The heat-conducting boss, acting as an intermediate medium for heat conduction, can quickly transfer the heat generated by the wireless charging module to the heat dissipation device.

[0017] As a preferred embodiment, the receiving slot includes a central receiving slot and an annular receiving slot, and the wireless charging module includes a coil assembly and a magnetic attraction structure. The coil assembly is disposed in the central receiving slot, and the magnetic attraction structure is disposed in the annular receiving slot, so that the coil assembly and the magnetic attraction structure are arranged side by side in the horizontal direction.

[0018] In the above technical solution, the coil assembly and magnetic structure are reasonably arranged by the layered layout of the central receiving slot and the annular receiving slot. This not only improves the integration and compactness of the wireless charging device, which is conducive to installation and use in limited spaces such as inside a vehicle, but also improves the heat dissipation efficiency and charging performance of the wireless charging module by optimizing the heat dissipation path and reducing electromagnetic interference.

[0019] As a preferred embodiment, the number of the heat-conducting top cover, the heat-conducting boss, and the heat dissipation device is greater than or equal to two.

[0020] In the above technical solution, two or more heat-conducting top covers and heat-conducting protrusions can be respectively equipped with two or more wireless charging modules, thereby forming two or more independent charging areas, that is, realizing a dual-charging area or multi-charging area solution; two or more heat dissipation devices can correspond to different charging areas respectively, realize targeted heat dissipation, and improve the reliability and stability of the dual-charging area or multi-charging area solution.

[0021] As a preferred embodiment, each of the heat-conducting top cover, each of the heat-conducting protrusions, and each of the heat dissipation devices are arranged side by side in the horizontal direction.

[0022] In the above technical solution, the heat-conducting top cover, heat-conducting boss and heat dissipation device are arranged in sequence along the vertical direction, so that the various components are arranged closely in space, reducing the vertical height and further improving the space utilization rate.

[0023] As a preferred embodiment, the panel is detachably mounted above the bracket, and the panel presses and secures the thermally conductive top cover and the thermally conductive protrusion onto the bracket.

[0024] In the above technical solution, the detachability of the panel makes it more convenient to install or replace internal components such as wireless charging modules, heat-conducting components or heat dissipation devices, thereby improving the maintainability and scalability of the device.

[0025] As a preferred embodiment, the bottom side of the heat-conducting top cover is provided with a first outer edge, the bottom side of the heat-conducting protrusion is provided with a second outer edge, the bottom side of the panel abuts against the first outer edge, the first outer edge abuts against the second outer edge, and the second outer edge abuts against the bracket, thereby pressing and fixing the heat-conducting top cover and the heat-conducting protrusion onto the bracket through the panel.

[0026] In the above technical solution, the multi-layer abutment design enables a tight mechanical connection between the panel, the heat-conducting top cover, the heat-conducting boss and the bracket, ensuring the stability of each component during use, and eliminating the need for additional connecting parts, simplifying the overall structure and reducing maintenance costs and difficulties.

[0027] In summary, the wireless charging device based on space optimization design provided by this utility model has at least the following technical advantages compared with the prior art:

[0028] 1) This utility model can achieve a high degree of integration of wireless charging device. The bracket, panel and back cover form a housing space. The layout of each component is optimized in the housing space. While ensuring the wireless charging efficiency, heat dissipation efficiency and other functions, the vertical height dimension is minimized, the overall structure is more compact, saves the space in the vehicle, and improves the user experience. It is especially suitable for dual charging area or multi-charging area wireless charging solutions, and provides a better solution for the development of vehicle wireless charging technology.

[0029] 2) The shapes of the heat-conducting top cover and the heat-conducting protrusion are adapted to each other, and the combination of the two realizes three major functions in one: accommodating the wireless charging module, supporting the device to be charged, and conducting heat to the heat source. This integrated design significantly reduces the use of other unnecessary structures, and effectively reduces the overall height of the charging module while ensuring product performance, making the product more compact and lightweight, and providing strong support for further optimization of in-vehicle wireless chargers.

[0030] 3) By designing the circuit board inside the space to avoid gaps, the heat dissipation device and the circuit board can be arranged side by side in the horizontal direction, which minimizes the space required in the vertical direction. Compared with the traditional stacking method, the height of the wireless charging module is reduced, the space utilization is improved, and at the same time, it can ensure that the heat dissipation device and the circuit board maintain a good heat transfer path, avoiding the problem of reduced heat dissipation efficiency due to excessive distance or structural obstruction.

[0038] 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.

[0039] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in 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.

[0040] 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.

[0041] See Figures 1-5 As shown, in the technical solution of this utility model, the wireless charging device based on space optimization design includes a bracket 1. A panel 2 and a rear cover 3 are respectively provided on the upper and lower sides of the bracket 1. A receiving space is formed between the bracket 1, panel 2, and rear cover 3. The receiving space is equipped with a heat-conducting protrusion 4, a heat-conducting upper cover 5, a heat dissipation device 6, and a circuit board 8. Preferably, the receiving space formed by the bracket 1, panel 2, and rear cover 3 is a semi-enclosed space, providing basic physical support and protection for the heat-conducting protrusion 4, heat-conducting upper cover 5, heat dissipation device 6, and circuit board 8 inside. Specifically, by optimizing the layout of each component within the receiving space, while ensuring wireless charging efficiency and heat dissipation efficiency, the vertical height of the wireless charging device is minimized, resulting in a more compact overall structure and saving vehicle interior space. This is particularly suitable for dual-charging-zone or multi-charging-zone wireless charging solutions.

[0042] See Figure 1 , Figure 3 and Figure 4 As shown, panel 2 has several first through holes 21. A heat-conducting protrusion 4 and a heat-conducting cover 5 extend from the first through holes 21, with the heat-conducting cover 5 positioned above the heat-conducting protrusion 4. A wireless charging module 9 is positioned between the heat-conducting cover 5 and the heat-conducting protrusion 4. The area between the heat-conducting protrusion 4 and the heat-conducting cover 5 can accommodate the wireless charging module 9, and the heat-conducting protrusion 4, by supporting the heat-conducting cover 5, also supports the device to be charged on the heat-conducting cover 5. Furthermore, the heat-conducting protrusion 4 and the heat-conducting cover 5 also serve as heat conduction channels to conduct heat generated by the device to be charged and the wireless charging module 9 to the heat dissipation device 6. Thus, by adapting the shapes of the heat-conducting cover 5 and the heat-conducting protrusion 4, the three functions of accommodating the wireless charging module 9, supporting the device to be charged, and conducting heat to the heat source can be integrated into one unit, effectively reducing the overall height of the charging module and making the product more compact and lightweight.

[0043] See Figure 1 and Figure 3 As shown, the heat dissipation device 6 is connected to the heat-conducting protrusion 4, and the circuit board 8 has a clearance 81 through which the heat dissipation device 6 passes, so that the heat dissipation device 6 and the circuit board 8 are arranged side by side in the horizontal direction. Specifically, through the design of the clearance 81 of the circuit board 8, the heat dissipation device 6 and the circuit board 8 can be arranged side by side in the horizontal direction, minimizing the space required by both in the vertical direction. Compared with the traditional stacking method, this reduces the height of the wireless charging module, improves space utilization, and ensures a good heat transfer path between the heat dissipation device 6 and the circuit board 8, avoiding the problem of reduced heat dissipation efficiency due to excessive distance or structural obstruction.

[0044] It is worth mentioning that the clearance 81 provided on the circuit board 8 can be an open notch on the edge of the circuit board 8 (such as...). Figure 1 As shown in the diagram, a through hole can also be provided in the middle of the circuit board 8, running vertically through it. Regardless of the structural form, as long as the heat sink 6 can pass through and the heat sink 6 and the circuit board 8 are arranged side by side in the horizontal direction, it is acceptable.

[0045] Example 1

[0046] In a preferred embodiment of this utility model, a structural design scheme for a heat dissipation system of a wireless charging device is provided.

[0047] See Figure 3 and Figure 4 As shown, in this embodiment, the heat dissipation device 6 includes a heat dissipation body 61 and heat sinks 62. The heat dissipation body 61 is connected to the heat-conducting protrusion 4, and multiple heat sinks 62 are spaced apart on the bottom side of the heat dissipation body 61. The heat dissipation body 61 is responsible for connecting to the heat-conducting protrusion 4, serving to receive and conduct heat. The heat sinks 62 are spaced apart on the bottom side of the heat dissipation body 61, increasing the heat dissipation area to accelerate heat dissipation and thus improve the overall heat dissipation efficiency of the heat dissipation device 6.

[0048] Specifically, the heat sink 62 significantly increases the contact area between the heat dissipation device 6 and the surrounding air, thereby achieving more efficient heat exchange, accelerating heat dissipation, effectively reducing heat accumulation during operation, and improving heat dissipation efficiency. Furthermore, placing the heat sink 62 on the bottom side of the heat dissipation body 61 avoids excessive vertical space occupation and prevents its placement in other locations on the heat dissipation body 61 (such as the side) from affecting the spatial arrangement of components such as the circuit board 8 arranged alongside it.

[0049] See Figure 1As shown, in a preferred embodiment, the wireless charging device based on space-optimized design further includes a cooling fan 7. The cooling fan 7 and the heat dissipation device 6 are arranged side by side in the horizontal direction, and the cooling fan 7 is adjacent to or attached to the circuit board 8. The cooling fan 7, as an additional heat dissipation component of the wireless charging device, is closely integrated with the heat dissipation device 6 in its layout, together forming a heat dissipation system. On the one hand, when the cooling fan 7 is working, it can actively drive the surrounding airflow, accelerating the dissipation of heat around the heat sink 62 and the heat dissipation body 61, further improving heat dissipation efficiency. On the other hand, through the above-mentioned layout, the cooling fan 7 can directly act on the circuit board 8 to dissipate heat, thereby maintaining the stable operation of the electronic components on the circuit board 8, avoiding performance degradation or damage to components due to overheating, and improving the reliability and service life of the entire wireless charging device.

[0050] Furthermore, the number of cooling fans 7 is at least two, and each cooling fan 7 can be controlled independently, so that multiple cooling fans 7 can be turned on individually or simultaneously. For example, when only one mobile device needs to be charged, the cooling fan 7 of the corresponding area can be turned on; when two or more mobile devices need to be charged, multiple cooling fans 7 can be turned on simultaneously.

[0051] See Figure 1 As shown, in another preferred embodiment, the rear cover 3 is provided with a second through hole 31, and the cooling fan 7 includes an air inlet and an air outlet. One of the air inlet and the air outlet is provided corresponding to the second through hole 31, and the other is provided corresponding to the heat sink 62. Specifically, taking the air inlet being provided corresponding to the second through hole 31 and the air outlet being provided corresponding to the heat sink 62 as an example, cold air from outside the device enters through the second through hole 31 of the rear cover 3 and is drawn in by the cooling fan 7; the cooling fan 7 blows the cold air toward the heat sink 62, and the cold air flows over the surface of the heat sink 62, carrying away the heat on the heat sink 62; the hot air carrying heat is discharged from around the heat sink 62, completing the heat dissipation process.

[0052] Similarly, with the air outlet corresponding to the second through hole 31 and the air inlet corresponding to the heat sink 62 as an example, the cooling fan 7 draws in hot air from around the heat sink 62; after passing through the cooling fan 7, the hot air is discharged to the outside of the device through the second through hole 31; the cold air from the outside enters the area of ​​the heat dissipation device 6 from other gaps or through holes, forming an air circulation and achieving a heat dissipation effect.

[0053] Through the above structural design, the cooling fan 7, the heat sink 62 and the second through hole 31 of the rear cover 3 can be organically combined to form a complete heat dissipation system. The various parts cooperate and work together to improve the reliability and efficiency of the entire heat dissipation system, and at the same time make the layout of the heat dissipation system more reasonable.

[0054] It is worth mentioning that the “setting corresponding to the second through hole 31” or “setting corresponding to the heat sink 62” described in this embodiment includes, but is not limited to, structural design forms such as being oriented toward the second through hole 31, the heat sink 62 or being adjacent to the second through hole 31, the heat sink 62.

[0055] Example 2

[0056] In another preferred embodiment of this utility model, a specific structural design scheme for the heat-conducting boss 4 and the wireless charging module 9 is provided.

[0057] See Figure 4 and Figure 5 As shown, in this embodiment, the top side of the heat-conducting boss 4 is provided with a receiving groove 42, and the wireless charging module 9 is disposed in the receiving groove 42. Specifically, by placing the wireless charging module 9 in the receiving groove 42 of the heat-conducting boss 4, there is no need to set up additional support or receiving structure, so that each component can be reasonably arranged and compactly arranged, further optimizing the internal structure of the entire wireless charging device, and also providing more space for the arrangement of other components.

[0058] Furthermore, the design of the receiving slot 42 ensures that the wireless charging module 9 is fixed in position on the heat-conducting boss 4, reducing the risk of module displacement due to vibration or external force during use, and improving the stability and reliability of the device. In addition, since the wireless charging module 9 is located in the receiving slot 42 of the heat-conducting boss 4, heat can be conducted more directly to the heat-conducting boss 4. As an intermediate medium for heat conduction, the heat-conducting boss 4 can quickly transfer the heat generated by the wireless charging module 9 to the heat dissipation device 6.

[0059] See Figure 4 and Figure 5 As shown, in a preferred embodiment, the receiving slot 42 includes a central receiving slot 421 and an annular receiving slot 422. The wireless charging module 9 includes a coil assembly 91 and a magnetic structure 92. The coil assembly 91 is disposed in the central receiving slot 421 and the magnetic structure 92 is disposed in the annular receiving slot 422, so that the coil assembly 91 and the magnetic structure 92 are arranged side by side in the horizontal direction.

[0060] The coil assembly 91 is the core component of the wireless charging module 9, responsible for electromagnetic induction to achieve wireless charging. Its placement within the central receiving slots 421 and 42 ensures stable operation during charging, reducing the impact of vibration and displacement on charging efficiency. It also facilitates centralized heat dissipation, ensuring optimal performance. The magnetic structure 92 creates an attractive force between the wireless charging module 9 and the device being charged, making the device more stable during charging and less prone to displacement due to external forces. Positioning the magnetic structure 92 within the annular receiving slots 422 ensures its horizontal alignment with the coil assembly 91, maximizing space utilization, and also minimizes electromagnetic interference from the magnetic structure 92 to the coil assembly 91, ensuring the stability and safety of wireless charging.

[0061] Therefore, the above structural design fully considers the balance between space utilization, functional realization and performance guarantee of the wireless charging device. Through the layered layout of the central receiving slot 421, receiving slot 42 and the annular receiving slot 422, the coil assembly 91 and the magnetic attraction structure 92 are reasonably arranged. This not only improves the integration and compactness of the wireless charging device, which is conducive to installation and use in limited spaces such as inside a vehicle, but also improves the heat dissipation efficiency and charging performance of the wireless charging module 9 by optimizing the heat dissipation path and reducing electromagnetic interference, providing users with a more stable and efficient wireless charging experience.

[0062] Example 3

[0063] In another preferred embodiment of this utility model, a structural design method for a wireless charging device in a dual-charging-zone or multi-charging-zone scheme is provided.

[0064] See Figure 1 As shown, in this embodiment, the number of heat-conducting top cover 5, heat-conducting protrusion 4, and heat dissipation device 6 is greater than or equal to two. Two or more heat-conducting top covers 5 and heat-conducting protrusions 4 can correspondingly provide two or more wireless charging modules 9, thereby forming two or more independent charging areas, thus realizing a dual-charging-area or multi-charging-area solution.

[0065] More specifically, in the aforementioned dual-charging-zone or multi-charging-zone scheme, each charging zone has an independent wireless charging module 9, and two or more heat dissipation devices 6 can correspond to different charging zones respectively, achieving targeted heat dissipation. This ensures that the heat dissipation needs of each charging zone are met, and that heat dissipation is timely and effective regardless of which zone's wireless charging module 9 is operating, improving the reliability and stability of the multi-charging-zone scheme. Furthermore, multiple heat dissipation devices 6 can be flexibly arranged according to the internal spatial layout of the wireless charging device and the distribution of various components, avoiding mutual interference between heat dissipation devices 6, while maximizing space utilization, making the overall device structure more compact, and better adapting to environments with limited space, such as in vehicles.

[0066] Preferably, there are two thermally conductive top cover 5, thermally conductive protrusion 4, and heat dissipation device 6, so that the wireless charging device of this utility model can realize a dual charging zone scheme.

[0067] See Figure 1 and Figure 3 As shown, in a preferred embodiment, each heat-conducting cover 5, each heat-conducting protrusion 4, and each heat dissipation device 6 are arranged side by side in the horizontal direction, and the heat-conducting cover 5, heat-conducting protrusion 4, and heat dissipation device 6 are arranged sequentially in the vertical direction, so that each component is arranged closely in space, reducing the vertical height and further improving the space utilization rate.

[0068] Example 4

[0069] In another preferred embodiment of this utility model, a structural design scheme for fixing the heat-conducting top cover 5 and the heat-conducting boss 4 is provided.

[0070] See Figure 1 and Figure 3 As shown, in this embodiment, the panel 2 is detachably mounted on top of the bracket 1, and the panel 2 presses and fixes the heat-conducting cover 5 and the heat-conducting protrusion 4 onto the bracket 1, ensuring that the heat-conducting cover 5 and the heat-conducting protrusion 4 remain stable during use, reducing displacement or loosening caused by vibration or external force, thereby ensuring the normal operation of the wireless charging module 9 and good heat conduction effect. The detachability of the panel 2 makes it more convenient to install or replace internal components such as the wireless charging module 9, heat-conducting components, or heat dissipation device 6. Only the panel 2 needs to be removed for direct repair, replacement, or upgrade operations, greatly improving the maintainability and scalability of the device.

[0071] See Figure 4As shown, in a preferred embodiment, the bottom side of the heat-conducting cover 5 has a first outer edge 51, and the bottom side of the heat-conducting boss 4 has a second outer edge 41. The bottom side of the panel 2 abuts against the first outer edge 51, the first outer edge 51 abuts against the second outer edge 41, and the second outer edge 41 abuts against the bracket 1. Thus, after the panel 2 is installed, the heat-conducting cover 5 and the heat-conducting boss 4 can be pressed and fixed onto the bracket 1 by the panel 2. Through the above-mentioned multi-layer abutment design, a tight mechanical connection is formed between the panel 2, the heat-conducting cover 5, the heat-conducting boss 4, and the bracket 1, ensuring the stability of each component during use, effectively preventing loosening or displacement of components due to vibration or external force, and improving the reliability of the entire device.

[0072] Furthermore, the aforementioned abutment design eliminates the need for additional connecting parts (such as bolts), simplifying the overall structure. When internal components need to be repaired or replaced, there is no need to disassemble a large number of connecting parts. Simply open panel 2 to access the corresponding components, which is convenient, quick, and reduces maintenance costs and difficulty.

[0073] It is worth mentioning that the first outer edge 51 can be a protruding structure formed by folding the bottom side of the heat-conducting top cover 5 outward, and the second outer edge 41 can be a protruding structure formed by folding the bottom side of the heat-conducting boss 4 outward.

[0074] 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.
