[0002] With the development of electric vehicles, the use of vehicle-mounted display screens is increasing, and the vehicle-mounted backlight module is used for normal image display of the display screen.

[0003] The announcement number is CN219609389U, a support structure, a backlight module and a display device, the support structure comprising: a support plate, the support plate is a plastic material; the support plate has a first support portion and a second support portion, one end of the first support portion is used to connect to the housing, the other end of the first support portion is connected to one end of the second support portion, and the other end of the second support portion is used to abut against a diffusion plate; there is a first angle between the first support portion and the second support portion, and the first angle is less than 180°. The support structure disclosed in the utility model can solve the technical problem that the display device currently using a direct-type backlight module is prone to screen damage when it is squeezed or collided.

[0004] The diffuser plate is supported by the second supporting portion, so that when the display device is squeezed, collided, etc., the second supporting portion bends to provide supporting force to play a buffering role and prevent the diffuser plate from collapsing. However, the second supporting portion is in a pointed shape, so when the diffuser plate is squeezed and bent, the corners of the second supporting portion will rub against the bottom end of the diffuser plate, causing scratches on the bottom end of the diffuser plate, affecting the use of the diffuser plate. Utility Model Content

[0005] The purpose of the utility model is to provide a vehicle-mounted backlight module support assembly to solve the problems raised in the above-mentioned background technology.

[0018] Technical effects and advantages of the utility model:

[0019] The utility model utilizes the design of the support member, the buffer column and the diffuser plate.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-4 A vehicle-mounted backlight module support assembly is shown, comprising:

[0027] A support member 1 and a buffer column 2, a mounting plate 3 for mounting the support member 1 is disposed at the bottom end of the support member 1, a diffusion plate 8 supported by the support member 1 is disposed at the top end of the support member 1, a light source member 6 for emitting light is disposed at one side of the support member 1, a housing 5 for mounting the light source member 6 is disposed outside the light source member 6, and a vehicle-mounted display screen 9 for vehicle-mounted image display is disposed at the top end of the housing 5;

[0028] Specifically, the support member 1 includes a support plate 11, the vertical cross-section of the support plate 11 is arc-shaped, and a buffer plate 13 for installing the buffer column 2 is arranged at the bottom end of the support plate 11, and a first connecting plate 12 for connecting with the buffer plate 13 is fixedly connected to the bottom end of the support plate 11, and the bottom end of the first connecting plate 12 is fixedly connected to the top end of the buffer plate 13, and the bottom end of the buffer plate 13 is fixedly connected to the second connecting plate 14, and the bottom end of the second connecting plate 14 is fixedly connected to a mounting plate 3 for connecting with the outer shell 5, and mounting holes 4 for installing fixing bolts are respectively provided on both sides of the top end of the mounting plate 3, and the buffer plate 13 is V-shaped, and the angle of the buffer plate 13 is 30°, and the top and bottom ends of the buffer column 2 are respectively fixedly connected to the top and bottom ends of the inner wall of the buffer plate 13, and the buffer column 2 is used to support the buffer plate 13, and the vertical cross-section of the buffer column 2 is arc-shaped.

[0029] Furthermore, the thickness of the mounting hole 4 is lower than the height of the light source emitted by the light source part 6, and the mounting hole 4 is fixedly connected to the bottom end of the inner wall of the shell 5 by bolts. The support member 1 is made of polycarbonate, which has certain impact strength and bending performance, and is also highly transparent, so as not to reduce the impact on the light emitted by the light source part 6. The support plate 11, the first connecting plate 12, the buffer plate 13 and the second connecting plate 14 are cast in one piece, and the buffer column 2 is made of silicone. Silicone is a common transparent elastic rubber with good elasticity. At the same time, its transparency can reduce the impact on the light emitted by the light source part 6. The top and bottom ends of the buffer column 2 are fixedly connected to the contact surface of the buffer plate 13 by gluing, respectively. A plurality of support members 1 are arranged at equal intervals at the bottom end of the inner wall of the shell 5 to support multiple parts of the bottom end of the diffuser plate 8. A first connecting plate 12 is arranged on both sides of the bottom end of the support plate 11, a buffer plate 13 is arranged at the bottom end of the first connecting plate 12, and a The bottom end of the second connecting plate 14 is symmetrically arranged and fixedly connected to the two sides of the top of the mounting plate 3 by gluing. The opening directions of the symmetrically arranged buffer plates 13 are arranged in opposite directions. Therefore, when the diffuser plate 8 squeezes the contacting portion of the top of the support plate 11, the support plate 11 will be squeezed toward the mounting plate 3, and the support plate 11 drives the first connecting plate 12 to squeeze the buffer plate 13. The V-shaped opening of the buffer plate 13 begins to shrink, thereby squeezing the buffer column 2 inside the buffer plate 13. The restoring force of the buffer column 2 after being squeezed will push the buffer plate 13 to restore its original state, thereby driving the support plate 11 to provide supporting force to the diffuser plate 8 through the first connecting plate 12, so that the diffuser plate 8 is restored to its original state and the continuous use of the diffuser plate 8 is maintained. At the same time, the outer wall of the top of the support plate 11 is smoothly polished, which cooperates with the arc shape of the support plate 11 itself. When supporting the diffuser plate 8, the friction damage of the support plate 11 to the bottom of the diffuser plate 8 can be greatly reduced.

[0030] Specifically, a reflective sheet 7 for reflecting light emitted by the light source 6 is disposed at the bottom end of the inner wall of the housing 5 , and the bottom end of the vehicle-mounted display screen 9 is fixedly connected to the top end of the housing 5 .

[0031] Furthermore, the shell 5 is a metal frame for installing components such as a vehicle-mounted display screen 9, a light source component 6, a reflective sheet 7, and a diffuser plate 8. The vehicle-mounted display screen 9 is an existing vehicle-mounted display screen. The vehicle-mounted display screen 9 is fixedly connected to the top of the shell 5 by bolts, and the reflective sheet 7 is adhered to the bottom end of the inner wall of the shell 5 by gluing. The arrangement and fixing methods of components such as the light source component 6, the reflective sheet 7 and the diffuser plate 8 are all the arrangement and installation methods of the existing backlight module.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
