Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to a secure fastening device for vehicle backlighting. Background Technology

[0002] With the popularization of new energy vehicles, the traditional stamping design of automotive screen hardware is gradually adopting aluminum die-casting and magnesium die-casting backlight module designs. This places higher demands on frame strength and narrower frame widths, along with aesthetically pleasing and simplified component designs. Furthermore, the integration of these factors with end-customer automotive three-dimensional testing necessitates innovative fusion and higher product structural robustness. The three-dimensional testing refers to a comprehensive test involving temperature, humidity, and vibration—three environmental stresses—to realistically expose product defects. The combined effects of these environmental factors more accurately reflect the product's performance in field use and reveal its flaws. Applying individual environmental stresses to the product can induce malfunctions; applying three different environmental stresses can easily result in a 3-5 times acceleration effect. Vibration conditions place higher demands on the product's structural design and the robustness of the assembly of various components.

[0003] Currently, traditional snap-fit ​​devices mostly use plastic frames for snap-fit. In the traditional plastic frame snap-fit ​​backlight module design, the plastic frame is injection molded. The plastic is relatively soft and easily deformed. In addition, the thick frame is not conducive to narrow frame design. Plastic deformation is not conducive to snap-fit ​​assembly and locking, and there is a risk of warping. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings in the prior art and to propose a secure fastening device for vehicle backlighting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted backlight secure fastening device, including a base plate, a limiting plate vertically installed along the side edge of the base plate, a backlight module built into the limiting plate, and the edge of the backlight module fitting with the inner wall of the limiting plate with a clearance.

[0006] Multiple spaced limiting grooves are provided on the inner wall of the limiting plate. A frame-type pressure plate is provided on the inner wall of the limiting plate away from the bottom plate. A connecting plate is vertically installed on the edge of the pressure plate away from the backlight module. Multiple limiting blocks are installed on the outer wall of the connecting plate, and the limiting blocks correspond to the limiting grooves.

[0007] Preferably, a plurality of first receiving grooves are provided on the side of the limiting plate away from the bottom plate. The first receiving grooves are "T" shaped and the narrow side ends are arranged through the limiting plate. A plurality of first receiving plates are installed on the outer wall of the connecting plate. The first receiving plates correspond to the first receiving grooves, and there is a gap between the outer wall of the first receiving plate and the inner wall of the first receiving groove.

[0008] Preferably, a number of second receiving grooves are provided on the side of the limiting plate away from the bottom plate. The second receiving grooves penetrate the inner side of the limiting plate, and a second receiving plate is also installed on the outer wall of the connecting plate. The second receiving plate corresponds to the second receiving groove.

[0009] Preferably, magnetic clasps are installed on the sides of the first receiving plate and the first receiving groove that are relatively close to each other, and the two magnetic clasps attract each other to magnetically fix the first receiving plate in the first receiving groove.

[0010] Preferably, the limiting block is a sheet metal with an opening on one side near the connecting plate, and both the limiting block and the first receiving plate are made of SUS304 or SUS430 sheet metal, with a thickness of A, where A≥0.3mm.

[0011] Preferably, a number of magnets are installed on the inner wall of the limiting plate at intervals, and a fixing plate is installed on the side of the pressure plate away from the bottom plate, with the fixing plate and the magnets magnetically attracted to each other.

[0012] Preferably, a strip-shaped movable groove is provided on one side of the limiting plate, and a movable plate is installed on the side of the pressure plate near the bottom plate.

[0013] Preferably, a number of spaced mounting bases are installed on the side of the base plate away from the backlight module, and the mounting bases are provided with screw holes.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1. This utility model enhances the fixing effect of the backlight module by combining the limiting plate, limiting groove and limiting block with the frame design of the pressure plate and connecting plate, and effectively prevents loosening or warping under vibration.

[0016] 2. By introducing magnetic absorbing sheets (such as the magnetic attraction design between the first accommodating plate and the first accommodating groove) and magnets, this utility model further improves the adsorption stability of the component and avoids displacement caused by vehicle vibration.

[0017] 3. This utility model uses SUS304 or SUS340 sheet metal material to replace the traditional plastic frame, which solves the problems of easy deformation and thick frame of plastic, and meets the requirements of vehicle screen for narrow frame and high strength. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference 1- Figure 6 A secure mounting device for vehicle backlight includes a base plate 1. Several spaced mounting seats 16 are installed on the side of the base plate 1 away from the backlight module 5. The mounting seats 16 are provided with screw holes for mounting the base plate 1 on the vehicle frame.

[0027] A limiting plate 2 is vertically installed along the side edge of the base plate 1. A backlight module 5 is built into the limiting plate 2. The edge of the backlight module 5 is fitted with the inner wall of the limiting plate 2. In actual use, both the limiting plate 2 and the base plate 1 are made of sheet metal, using one of SUS304 or SUS430, to improve the strength of the base plate 1 and the limiting plate 2.

[0028] Multiple spaced limiting grooves 11 are provided on the inner wall of the limiting plate 2. A frame-type pressure plate 6 is provided on the inner wall of the limiting plate 2 away from the bottom plate 1. A connecting plate 7 is vertically installed on the edge of the pressure plate 6 away from the backlight module 5. Multiple limiting blocks 10 are installed on the outer wall of the connecting plate 7. The limiting blocks 10 correspond to the limiting grooves 11. In actual use, the limiting grooves 11 are provided on the two opposite sides of the limiting plate 2. There is a gap between the side of the pressure plate 6 near the limiting groove 11 and the limiting plate 2. The sum of the gaps on both sides corresponds to the width of the limiting block 10. After the limiting block 10 on one side is completely pressed into the corresponding limiting groove 11, the entire pressure plate 6 can be laid flat on the backlight module 5. This makes it convenient to push the limiting block 10 on the other side of the pressure plate 6 into the corresponding limiting groove 11. In this way, the pressure plate 6 can press on the backlight module 5 to fix the backlight module 5 on the limiting plate 2.

[0029] After the pressure plate 6 is placed inside the limiting plate 2, multiple first receiving grooves 3 are provided on the side of the limiting plate 2 away from the bottom plate 1. The first receiving grooves 3 are "T"-shaped and the narrow side ends are oriented towards the inside of the limiting plate 2. Multiple first receiving plates 8 are installed on the outer wall of the connecting plate 7. The first receiving plates 8 correspond to the first receiving grooves 3 and are also placed in the first receiving grooves 3. Several second receiving grooves 4 are also provided on the side of the limiting plate 2 away from the bottom plate 1. The second receiving grooves 4 penetrate the inside of the limiting plate 2. A second receiving plate 9 is also installed on the outer wall of the connecting plate 7. The second receiving plate 9 corresponds to the second receiving grooves 4. This achieves multi-directional limiting and fixing of the pressure plate 6 within the limiting plate 2. A gap is left between the outer wall of the first receiving plate 8 and the inner wall of the first receiving groove 3 to ensure that the movement of the pressure plate 6 within the limiting plate 2 does not affect the installation of the limiting block 10 within the limiting groove 11.

[0030] It should be noted that magnetic clasps 12 are installed on the side of the first receiving plate 8 that is relatively close to the first receiving groove 3. The two magnetic clasps 12 attract each other, so that the first receiving plate 8 is magnetically fixed in the first receiving groove 3. This can reinforce the first receiving plate 8 in the first receiving groove 3, so as to prevent the pressure plate 6 from accidentally moving in the limiting plate 2 during use, which would cause the pressure plate 6 to easily detach from the limiting plate 2 due to vibration or other reasons, thus affecting the installation of the backlight module 5.

[0031] In order to further improve the fixing effect of the pressure plate 6 within the limiting plate 2, a number of magnets are installed on the inner wall of the limiting plate 2 at intervals, and a fixing plate 13 is installed on the side of the pressure plate 6 away from the bottom plate 1, and the fixing plate 13 and the magnets are magnetically attracted to each other.

[0032] Furthermore, the limiting block 10 is a sheet metal with an opening on the side near the connecting plate 7, and both the limiting block 10 and the first receiving plate 8 are made of SUS304 or SUS430 sheet metal, with a thickness of A, where A≥0.3mm. By using SUS304 or SUS340 sheet metal material to replace the traditional plastic frame, the problems of easy deformation and thick frame of plastic are solved, thus meeting the requirements of the vehicle screen for narrow frame and high strength.

[0033] Specifically, during use, a strip-shaped movable groove 14 is provided on one side of the limiting plate 2, and a movable plate 15 is installed on the side of the pressure plate 6 near the bottom plate 1. The movable plate 15 corresponds to the movable groove 14, and there is a gap between the end of the movable plate 15 and the end of the movable groove 14. An independent movable plate 15 is placed on the outside, which makes it convenient for workers to control the movement of the pressure plate 6 in the limiting plate 2 through the movable plate 15, and to lift the pressure plate 6 to remove it from the limiting plate 2.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
