Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted backlight sources, and in particular to a vehicle-mounted backlight source with intelligent temperature control. Background Art

[0002] In modern vehicles, backlight, as an important component of liquid crystal display, plays a vital role in providing high-quality display effects. With the continuous upgrading of automotive electronic products, the performance requirements for vehicle-mounted backlight are getting higher and higher. Traditional vehicle-mounted backlight designs mostly use a plastic bottom shell with a metal heat sink to enhance structural strength and heat dissipation performance. However, with the development of LED technology, the power and brightness of LEDs continue to increase, and heat dissipation issues have become one of the key factors restricting the further development of backlight sources. Therefore, how to design an efficient heat dissipation structure to adapt to the heat generated by high-brightness LEDs has become a technical problem that urgently needs to be solved in the industry.

[0003] In order to improve the heat dissipation efficiency, a variety of heat dissipation structure designs have appeared in the prior art. A common practice is to use a metal material (such as aluminum) to make a bottom shell to replace the original plastic bottom shell, and set a heat sink or heat dissipation hole on the bottom shell to increase the heat dissipation area. At the same time, by installing an aluminum plate above the bottom shell and splicing each bottom shell into a complete heat dissipation chassis using screws or other connection means, the heat dissipation performance is improved to a certain extent. Since the joints between the two bottom shells are often the weak link in heat dissipation, if these areas cannot effectively conduct heat, it will cause local overheating, affecting the service life of the LED and the stability of the entire backlight source.

[0004] Therefore, it is necessary to provide a structural design of a vehicle-mounted backlight source with intelligent temperature control. Utility Model Content

[0032] The embodiment of the present application provides a vehicle-mounted backlight source with intelligent temperature control, including:

[0033] An installation aluminum plate, wherein the installation aluminum plate is provided with a first fixing hole and a second fixing hole;

[0034] A fastener, the fastener is placed on the mounting aluminum plate, and the fastener is provided with a third fixing hole and a fourth fixing hole;

[0035] A first bottom shell, the first bottom shell is placed under the mounting aluminum plate, and the first bottom shell is provided with a fifth fixing hole;

[0036] A second bottom shell, the second bottom shell is adjacent to the first bottom shell, and the adjacent joint seam is disposed under the mounting aluminum plate, and the second bottom shell is provided with a sixth fixing hole;

[0037] Heat sinks, a plurality of heat sinks are respectively disposed between the first bottom shell and the second bottom shell;

[0038] When the heat of the heat sink is transferred to the first bottom shell and the second bottom shell, and the heat reaches the joint between the first bottom shell and the second bottom shell, the heat is transferred to the fastener through the mounting aluminum plate on the joint.

[0039] The above provides an optimized heat dissipation structure design, by setting several fasteners on the mounting aluminum plate and ensuring that the position of the fasteners coincides with the joint seam of the bottom shell, so as to form an effective pressing contact between the two bottom shells under the mounting aluminum plate. Such a configuration not only enhances the thermal connection between the bottom shells, but also improves the overall heat dissipation efficiency through the excellent thermal conductivity of the fasteners, solving the problem of uneven heat dissipation and low efficiency caused by poor joints in the prior art.

[0040] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] See also Figure 1-Figure 5 An embodiment of the present application provides a vehicle-mounted backlight source with intelligent temperature control, including: an installation aluminum plate 10, a first bottom shell 30, a second bottom shell 40 and a heat sink 50.

[0042] The mounting aluminum plate 10 is provided with a first fixing hole 10a and a second fixing hole 10b. The fastener 20 is placed on the mounting aluminum plate 10, and the fastener 20 is provided with a third fixing hole 20a and a fourth fixing hole 20b. The first bottom shell 30 is placed under the mounting aluminum plate 10, and the first bottom shell 30 is provided with a fifth fixing hole 30a. The second bottom shell 40 is adjacent to the first bottom shell 30, and the adjacent joint seam is disposed under the mounting aluminum plate 10, and the second bottom shell 40 is provided with a sixth fixing hole 40a. A plurality of heat sinks 50 are respectively placed between the first bottom shell 30 and the second bottom shell 40.

[0043] When the heat of the heat sink 50 is transferred to the first bottom shell 30 and the second bottom shell 40 and reaches the joint between the first bottom shell 30 and the second bottom shell 40 , the heat is transferred to the fastener 20 through the mounting aluminum plate 10 on the joint.

[0044] Specifically, the mounting aluminum plate 10 is used as the main support and heat dissipation platform, and is designed with a first fixing hole 10a and a second fixing hole 10b, which provide fixing points for the fastener 20 and the bottom shell. The fastener 20 is placed on the mounting aluminum plate 10, and is provided with a third fixing hole 20a and a fourth fixing hole 20b, which are used to fix the mounting aluminum plate 10 and the bottom shell. The two bottom shells are respectively provided with fixing holes, which are aligned with the first fixing hole 10a and the second fixing hole 10b of the mounting aluminum plate 10. The second bottom shell 40 is adjacent to the first bottom shell 30, and the joint seam refers to the place where the first bottom shell 30 and the second bottom shell 40 are joined, which is located under the mounting aluminum plate 10, so that the heat sink 50 can be effectively placed between the two bottom shells. The sixth fixing hole 40a is also used for fixing with the fastener 20. The setting of the heat sink 50 is the core of the present technical solution, and multiple heat sinks 50 are respectively placed between the first bottom shell 30 and the second bottom shell 40. After the heat sink 50 absorbs the heat from the backlight source, the heat is transferred to the bottom case through the heat sink 50 , and then transferred to the mounting aluminum plate 10 and the fastener 20 through the bottom case.

[0045] Furthermore, the heat sink 50 is placed between the first bottom shell 30 and the second bottom shell 40 to ensure that they can effectively contact the two bottom shells to transfer heat. The mounting aluminum plate 10 is fixed to the bottom shell using the first fixing hole 10a and the second fixing hole 10b and the third fixing hole 20a and the fourth fixing hole 20b of the fastener 20 using the fixing member, so that the bottom shell is in close contact with the mounting aluminum plate 10. When the backlight source is working, the heat generated will be transferred to the heat sink 50 and then dissipated through the first bottom shell 30 and the second bottom shell 40. When the heat reaches the joint, the heat will be transferred to the fastener 20 through the thermal conductivity of the mounting aluminum plate 10, and then dissipated into the surrounding environment.

[0046] In a specific embodiment, the vehicle-mounted backlight source further includes a first fixing member 60 and a second fixing member 70 .

[0047] Among them, the first fixing hole 10a coincides with the third fixing hole 20a and the fifth fixing hole 30a, and the second fixing hole 10b coincides with the fourth fixing hole 20b and the sixth fixing hole 40a; the first fixing member 60 sequentially extends into the third fixing hole 20a, the first fixing hole 10a, and the fifth fixing hole 30a, and the second fixing member 70 sequentially extends into the fourth fixing hole 20b, the second fixing hole 10b, and the sixth fixing hole 40a, the first fixing member 60 is used to fix the mounting aluminum plate 10, the fastener 20 and the first bottom shell 30, and the second fixing member 70 is used to fix the mounting aluminum plate 10, the fastener 20 and the second bottom shell 40.

[0048] Specifically, the first fixing member 60 and the second fixing member 70 are key components of the entire backlight structure, and are tools or devices usually used to connect, fix or support two or more components, and may be one of screws, bolts, etc. The first fixing hole 10a overlaps with the third fixing hole 20a and the fifth fixing hole 30a, so that the first fixing member 60 can extend into the third fixing hole 20a, the first fixing hole 10a and the fifth fixing hole 30a, while the second fixing hole 10b overlaps with the fourth fixing hole 20b and the sixth fixing hole 40a, so that the second fixing member 70 can extend into the fourth fixing hole 20b, the second fixing hole 10b and the sixth fixing hole 40a. This design allows the fixing member to pass through the fixing holes of multiple components in series, thereby achieving a multi-level fixed connection.

[0049] Further, the fastener 20 is placed on the mounting aluminum plate 10, ensuring that the fixing holes of the fastener 20 are aligned with the corresponding fixing holes on the mounting aluminum plate 10. Subsequently, the first bottom shell 30 and the second bottom shell 40 are placed under the mounting aluminum plate 10, again ensuring that all the fixing holes are aligned. At this time, the first fixing member 60 is inserted through the third fixing hole 20a, the first fixing hole 10a and the fifth fixing hole 30a in sequence, so that the fastener 20, the mounting aluminum plate 10 and the first bottom shell 30 are fixed, and the second fixing member 70 is inserted through the fourth fixing hole 20b, the second fixing hole 10b and the sixth fixing hole 40a in sequence, so that the fastener 20, the mounting aluminum plate 10 and the second bottom shell 40 are fixed, completing the fixing of the entire device. The first fixing member 60 and the second fixing member 70 can ensure that the mounting aluminum plate 10, the fastener 20 and the bottom shell cannot move or loosen, thereby firmly fixing the mounting aluminum plate 10 and the two bottom shells together, so that the splicing gap between the first bottom shell 30 and the second bottom shell 40 is compressed, and the heat is dissipated to the mounting aluminum plate 10 and the fastener 20.

[0050] In a specific embodiment, the first bottom shell 30 is provided with a first contact surface 30b, a first placement surface 30c and a connecting portion 30d; the second bottom shell 40 is provided with a second contact surface 40b; the heat sink 50 is provided with a receiving surface 50a and a bottom surface 50b, and the first placement surface 30c is in conflict with the receiving surface 50a, so as to make the heat sink 50 contact with the first bottom shell 30 over a large area.

[0051] Specifically, the first bottom shell 30 includes three key surfaces: a first contact surface 30b, a first placement surface 30c and a connecting portion 30d. This allows the first bottom shell 30 to connect and interact with the heat sink 50 and other components to transfer heat. The first placement surface 30c provides a smooth surface on which the heat sink 50 can be placed, ensuring a large area of ​​contact and optimizing heat conduction. The connecting portion 30d is used to contact the connecting portions 30d of other components to ensure the stability of the structure and the correct assembly position. The second bottom shell 40 has a second contact surface 40b, which is similar to the design of the first bottom shell 30, with the purpose of providing stable support and an optimized heat dissipation path. The design of the heat sink 50 includes a receiving surface 50a and a bottom surface 50b, and the receiving surface 50a is in contact with the first placement surface 30c to improve the heat dissipation efficiency.

[0052] Furthermore, the heat sink 50 is placed on the first bottom case 30 and the second bottom case 40, ensuring that the receiving surface 50a of the heat sink 50 is in close contact with the first placement surface 30c of the first bottom case 30, ensuring that the heat sink 50 can transfer heat to the first bottom case 30, and then dissipate heat to the outside through the heat dissipation design of the bottom case. The design of the second bottom case 40 is similar to that of the first bottom case 30, and the purpose is to provide a heat dissipation path.

[0053] In a specific embodiment, the fastener 20 is a groove strip structure, and the fastener 20 is provided with a first outer concave surface 20c, a second outer concave surface 20d and a fastening portion 20e, the first outer concave surface 20c is flush with the first contact surface 30b, and the second outer concave surface is flush with the second contact surface 40b, which is used to make the fastener 20 flush with the bottom shell, and the third fixing hole 20a and the fourth fixing hole 20b are provided on the fastening portion 20e.

[0054] Specifically, the fastener 20 adopts a groove strip structure, which not only enhances the structural strength of the fastener 20 itself, but also facilitates fixed connection with other components such as the mounting aluminum plate 10. The first outer concave surface 20c is flush with the first contact surface 30b of the first bottom shell 30, ensuring the flat contact between the fastener 20 and the first bottom shell 30, which is conducive to maintaining the balance and stability of the entire device. The second outer concave surface 20d is flush with the second contact surface 40b of the second bottom shell 40, which ensures the close contact and overall stability between the fastener 20 and the second bottom shell 40. The fastening portion 20e is located at the center of the fastener 20, and the third fixing hole 20a and the fourth fixing hole 20b are part of the fastening portion 20e. Their positions correspond to the first fixing hole 10a and the second fixing hole 10b on the mounting aluminum plate 10, and are used to fix the fastener 20 to the mounting aluminum plate 10 by screws or other fixings. This fastening method not only enhances the structural stability of the entire vehicle-mounted backlight device, but also optimizes the heat dissipation effect.

[0055] Furthermore, the heat sink 50 is placed at an appropriate position on the first bottom shell 30, ensuring that the receiving surface 50a of the heat sink 50 is in conflict with the first placement surface 30c of the first bottom shell 30. The fastener 20 is aligned to the first bottom shell 30 and the second bottom shell 40 according to the design, so that the first outer concave surface 20c and the second outer concave surface 20d are respectively flush with the first contact surface 30b of the first bottom shell 30 and the second contact surface 40b of the second bottom shell 40, and the third fixing hole 20a and the fourth fixing hole 20b of the fastening part 20e are used to introduce screws or other fixings, and the fastener 20 and the mounting aluminum plate 10 are locked together, so that the heat inside the device can be effectively dissipated to the first bottom shell 30 and the second bottom shell 40 through the heat sink 50. When the heat is gathered at the joint between the first bottom shell 30 and the second bottom shell 40, the mounting aluminum plate 10 on the first bottom shell 30 and the second bottom shell 40 can transfer the heat to the fastener 20, thereby achieving the effect of heat dissipation.

[0056] In a specific embodiment, the mounting aluminum plate 10 is provided with a mounting portion 10c, the cross-sectional area of ​​the mounting portion 10c is equal to the cross-sectional area of ​​the fastening portion 20e, and the first fixing hole 10a and the second fixing hole 10b are provided on the fixing holes.

[0057] Specifically, the mounting portion 10c on the mounting aluminum plate 10 is provided with a first fixing hole 10a and a second fixing hole 10b, and the fixing holes are used to firmly connect the mounting aluminum plate 10 to the fastening portion 20e. The mounting portion 10c and the fastening portion 20e have equal cross-sectional areas, which means that they can be fully covered when joined without exposed parts, so that a uniform bearing surface can be provided, which helps to disperse stress, avoid local overload, and improve the strength and stability of the overall structure. The mounting aluminum plate 10 is provided with a first fixing hole 10a and a second fixing hole 10b, and the positions of these fixing holes correspond to the positions of the third fixing hole 20a and the fourth fixing hole 20b of the fastening portion 20e. The fixing holes are used to receive fixings so as to firmly connect the mounting aluminum plate 10 to the fastening portion 20e.

[0058] Further, the heat sink 50 is placed on the first bottom shell 30, and the first outer concave surface 20c and the second outer concave surface 20d of the fastener 20 are aligned with the first bottom shell 30 and the second bottom shell 40, and the mounting portion 10c of the mounting aluminum plate 10 is aligned with the fastening portion 20e of the fastener 20. Since their cross-sectional areas are equal, a tight fit can be achieved. The fixings are introduced through the first fixing holes 10a and the second fixing holes 10b, and the mounting aluminum plate 10 is firmly fixed to the fastening portion 20e. When the backlight source is working, the heat generated will be transferred to the heat sink 50, and then dissipated through the first bottom shell 30 and the second bottom shell 40. When the heat reaches the joint, the heat will be transferred to the fastener 20 through the thermal conductivity of the mounting aluminum plate 10, and then dissipated into the surrounding environment.

[0059] In a specific embodiment, the mounting aluminum plate 10 further includes: a plurality of corner connectors 11 and a plurality of frames 12 .

[0060] The multiple corner connectors 11 are disposed at the four corners of the mounting aluminum plate 10 , and the multiple frames 12 are closely disposed at the four sides of the mounting aluminum plate 10 , and the multiple corner connectors 11 are connected to the multiple frames 12 .

[0061] Specifically, the corner connectors can be made of metal or hard plastic, which can provide additional support and are welded at the four corners of the mounting aluminum plate 10. These corner connectors are used to enhance the strength of the mounting aluminum plate 10 at the corners to prevent deformation or damage during installation or use. Make the entire mounting aluminum plate 10 more solid. Multiple frames 12 are welded tightly on the four sides of the mounting aluminum plate 10. The function of the frame is to provide additional structural support around the edge of the mounting aluminum plate 10, protect the edge from damage, and increase the overall rigidity. The frame can also be used to connect the backlight panel to other components or housings. Multiple corner connectors 11 are embedded and spliced ​​with multiple frames 12, which means that there are connection points between the corner connectors and the frames, and the connection points can be achieved by screws, welding, riveting or other fixing methods. Such a design can ensure the overall stability of the mounting aluminum plate 10 and prevent any part from loosening or shifting.

[0062] Furthermore, multiple corner connectors 11 are installed at the four corners of the mounting aluminum plate 10, and then multiple frames 12 are placed close to the four sides of the mounting aluminum plate 10, and the corner connectors and the frames are embedded and spliced ​​together using an appropriate fixing method to form a solid frame structure.

[0063] In a specific embodiment, the vehicle-mounted backlight source further includes a mounting plate 80 .

[0064] The mounting plate 80 is provided with a mounting groove 80a and a supporting portion 80b. The mounting plate 80 is placed on the first bottom shell 30 and the heat sink 50, and the connecting portion 30d extends into the mounting groove 80a, and the supporting portion 80b is in conflict with the bottom surface 50b.

[0065] Specifically, the mounting plate 80 is a PCB board, which is used to place the first bottom shell 30, the second bottom shell 40 and the heat sink on the mounting plate 80. The mounting groove 80a is a groove or cutout on the mounting plate 80, which is used to accommodate the connecting portion 30d. The supporting portion 80b is a portion on the mounting plate 80 used to support the heat sink 50, which contacts the bottom surface 50b of the heat sink 50 to ensure that there is enough contact area between the heat sink 50 and the mounting plate 80, so that the heat of the mounting plate 80 can be transferred to the heat sink 50. The connecting portion 30d is inserted into the mounting groove 80a to ensure that the connection between the mounting plate 80 and the first bottom shell 30 is stable and not easy to loosen.

[0066] Further, the heat sink 50 is placed on the first bottom shell 30, and it is ensured that it conflicts with the first placement surface 30c of the first bottom shell 30, so as to maximize the contact area and effectively transfer heat. The mounting plate 80 is placed under the first bottom shell 30 and the heat sink 50, so that the connecting portion 30d is inserted into the mounting groove 80a, and the supporting portion 80b conflicts with the bottom surface 50b of the heat sink 50. The mounting plate 80 is fixed to the first bottom shell 30 by an appropriate fixing method (such as screws or welding), so that the heat sink 50 is stably fixed in place. The heat inside the device can be transferred to the heat sink 50 through the mounting plate 80, and the heat is transferred to the first bottom shell 30 and the second bottom shell 40 through the heat sink 50.

[0067] In a specific embodiment, the shape of the mounting groove 80 a matches the shape of the connecting portion 30 d , and is used to fix the mounting plate 80 and the first bottom shell 30 , thereby further improving the heat dissipation efficiency.

[0068] Specifically, the shape of the mounting groove 80a matches the shape of the connecting portion 30d to ensure that the mounting plate 80 can be accurately docked with the first bottom shell 30, so that the connecting portion 30d can be completely embedded in the mounting groove 80a. Through the connection between the mounting groove 80a and the connecting portion 30d, the mounting plate 80 and the first bottom shell 30 can be locked together using screws, snaps or other fixing mechanisms. This fixing method is not only stable, but also helps to form good thermal contact between the heat sink 50 and the first bottom shell 30, thereby improving the heat dissipation efficiency. When the connection between the mounting plate 80 and the first bottom shell 30 is stable, the heat sink 50 can distribute heat to the bottom shell more evenly, reducing thermal resistance, thereby improving the heat dissipation efficiency.

[0069] Furthermore, the heat sink 50 is placed on the first bottom case 30, and ensures that it contacts the first placement surface 30c of the first bottom case 30, so as to maximize the contact area and effectively transfer heat. The mounting plate 80 is aligned with the first bottom case 30, so that the connecting portion 30d is completely embedded in the mounting groove 80a, and the mounting plate 80 is fixed to the first bottom case 30 using an appropriate fixing mechanism (such as screws) to ensure the stability of the connection.

[0070] In a specific embodiment, the frame and the fastener 20 are both made of aluminum metal material to improve heat dissipation efficiency.

[0071] Specifically, the frame is used as a peripheral structure for mounting the aluminum plate 10, and the use of aluminum metal material can increase its thermal conductivity. Aluminum metal is a good thermal conductive material, which can effectively transfer the heat absorbed by the heat sink 50 to the frame, and then dissipate it into the surrounding environment. The fastener 20 is a strip-shaped structure of aluminum metal material, which is used to fix the various components together. The fastener 20 made of aluminum metal material not only has good corrosion resistance and strength, but also helps to transfer heat. When the fasteners 20 connect the heat dissipation related components, they can serve as a bridge for heat conduction, helping heat flow from the high temperature area to the low temperature area.

[0072] Further, the heat sink 50 is placed on the first bottom shell 30, and it is ensured that it conflicts with the first placement surface 30c of the first bottom shell 30, so as to maximize the contact area and effectively transfer heat. The mounting aluminum plate 10 is placed on the bottom shell, and it is ensured that the mounting portion 10c of the mounting portion 10c is aligned with the fastening portion 20e. The mounting aluminum plate 10 is fixed to the bottom shell using fasteners 20 made of aluminum metal, and at the same time, it is ensured that the corner connectors are connected to the frame to form a solid frame structure. When the heat is transferred to the mounting aluminum plate 10 through the heat sink 50, it is more effectively dissipated to the external environment through the aluminum metal frame and the fasteners 20.

[0073] In a specific embodiment, the vehicle-mounted backlight source further includes a corner connecting piece 90 .

[0074] The corner connecting piece 90 is placed on the corner connecting piece and the frame, and is used to connect and fix the corner connecting piece to the frames on both sides.

[0075] Specifically, the corner connector 90 is a structural member used to strengthen the corner part, which is usually made of metal or hard plastic. It provides additional support between the corner connector and the frame to prevent deformation or damage during installation or use. The corner connector 90 is located above the corner connectors and the frame at the four corners of the aluminum plate 10. The corner connector 90 connects the corner connector to the frames on both sides by screws, welding, riveting or other fixing methods. This design ensures the overall stability of the installed aluminum plate 10 and prevents any part from loosening or shifting.

[0076] Further, the heat sink 50 is placed on the first bottom shell 30, and the first outer concave surface 20c and the second outer concave surface 20d of the fastener 20 are used to align the first contact surface 30b of the first bottom shell 30 and the second contact surface 40b of the second bottom shell 40. The mounting aluminum plate 10 is placed on the bottom shell, and the mounting portion 10c of the mounting aluminum plate 10 is aligned with the fastening portion 20e. The fastener 20 and the mounting aluminum plate 10 are fixed to the first bottom shell 30 by the first fixing member 60, and the fastener 20 and the mounting aluminum plate 10 are fixed to the second bottom shell 40 by the second fixing member 70. A plurality of corner connectors 11 are installed to the four corners of the mounting aluminum plate 10, and a plurality of frames 12 are installed to the four sides of the mounting aluminum plate 10, and then the corner connector 90 is placed on the corner connector and the frame, and they are connected by an appropriate fixing method (such as screws or welding) to form a solid frame structure. When the backlight source is working, the heat generated will be transferred to the heat sink 50, and then dissipated through the first bottom shell 30 and the second bottom shell 40. When the heat reaches the joint between the first bottom shell 30 and the second bottom shell 40 , the heat is transferred to the fastener 20 through the thermal conductivity of the mounting aluminum plate 10 , and then dissipated into the surrounding environment.

[0077] Thus, by arranging several fasteners 20 on the mounting aluminum plate 10 and ensuring that the position of the fasteners 20 coincides with the joint seam of the bottom shell, an effective pressing contact is formed between the two bottom shells under the mounting aluminum plate 10. Such a configuration not only enhances the thermal connection between the bottom shells, but also improves the overall heat dissipation efficiency through the excellent thermal conductivity of the fasteners 20, solving the problem of uneven heat dissipation and low efficiency caused by poor joints in the prior art.

[0078] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
