Description

Technical Field

[0001] The utility model relates to the field of backlight sources, in particular to an LED backlight source with a protective structure. Background Art

[0002] Backlight is a light source behind the liquid crystal display (LCD). Its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). The LCD itself does not emit light, it displays graphics or the result of its light modulation. The backlight is mainly composed of light source, light guide plate, optical module, and structural parts.

[0003] However, in the prior art, during the installation of the backlight source, usually only the corners of the backlight source are protected. However, if the impact occurs in the middle of the backlight source, since there is no buffer support structure designed in this area, the backlight source can easily break, thereby reducing the service life of the backlight source. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an LED backlight source with a protective structure.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an LED backlight source with a protective structure, comprising a backlight source main body and a buffer box, the buffer box is fixedly connected with a support block inside, the upper end of the support block is provided with a damping rod, the upper end of the damping rod is fixedly connected with a slider, the upper end of the slider is fixedly connected with a pressure plate, the lower end of the pressure plate is fixedly connected with a hinge seat near the slider, the hinge seat is movably connected with a rotating plate inside, the other end of the rotating plate is movably connected with a moving seat, the buffer box is fixedly connected with a support block near the support block inside, one side of the support block is fixedly connected with a long rod, and the outside of the long rod is sleeved with a spring.

[0006] Preferably, a mounting plate is fixedly connected to the lower end of the backlight source body, arc-shaped plates are fixedly connected to both sides of the mounting plate, and threaded columns are fixedly connected to the lower ends of the arc-shaped plates.

[0007] Preferably, fixed plates are fixedly connected to both sides of the pressure plate, a clamping ring is fixedly connected to the top of the fixed plate, a clamping ring is movably connected inside the clamping ring, a short rod is fixedly connected to the top of the clamping ring, and a threaded sleeve is fixedly connected to the other end of the short rod.

[0008] Preferably, the movable seat slides outside the long rod through a spring.

[0009] Through the above scheme, the following technical effects can be achieved: the shock-absorbing assembly composed of the hinge seat, rotating plate, movable seat, long rod, damping rod and spring can form multiple shock-absorbing buffers, thereby reducing the impact on the backlight source body and also increasing its service life.

[0010] Preferably, the threaded columns are provided in multiple groups and are symmetrically arranged about the center line of the mounting plate.

[0011] Preferably, the threaded sleeve is movably connected to the fixing plate through a short rod clamp and a matching clamp ring.

[0012] Through the above scheme, the following technical effects can be achieved: the mounting plate can be quickly assembled and disassembled through components such as threaded sleeves, retaining rings, retaining rings, and threaded columns, so that the backlight source body on one side can be inspected, and the difficulty of maintenance can also be reduced.

[0013] By adopting the above technical scheme, when the backlight source body is hit, the provided damping rod can make the slider slide outside the support block, thereby achieving preliminary buffering and shock absorption. When the collision force of the backlight source body is large, the hinge seat causes the rotating plate to drive the moving seat to slide outside the long rod. During its sliding process, the spring will be squeezed, thereby converting the impact force into elastic potential energy, thereby achieving further buffering and shock absorption. The shock absorbing assembly composed of the hinge seat, rotating plate, moving seat, long rod, damping rod and spring can form multiple shock absorbing buffers, thereby reducing the impact on the backlight source body and increasing its service life.

[0014] By adopting the above technical solution, by rotating the threaded sleeve, the threaded column slides out of the threaded sleeve under the action of its internal thread, completing the separation of the mounting plate and the buffer box, that is, realizing the disassembly of the backlight source body. Similarly, during installation, the threaded column is slid into the threaded sleeve and rotated in the opposite direction, and the threaded column enters the interior of the threaded sleeve to complete the limiting and installation of the backlight source body. The mounting plate can be quickly loaded and unloaded through components such as the threaded sleeve, retaining ring, retaining ring, and threaded column, so that the backlight source body on one side can be inspected, and the difficulty of inspection can also be reduced.

[0023] Specifically, the damping rod 4 is arranged to enable the slider 5 to slide outside the support block 3, thereby achieving preliminary buffering and shock absorption. When the backlight source body 1 collides with a large force, the hinge seat 7 enables the rotating plate 8 to drive the moving seat 9 to slide outside the long rod 11.

[0026] Specifically, the threaded sleeve 17 is rotated, and under the action of its internal thread, the threaded column 20 slides out from the threaded sleeve 17, completing the separation of the mounting plate 18 and the buffer box 2, that is, realizing the disassembly of the backlight source body 1.

When the backlight source body 1 is hit with great force, the hinge seat 7 makes the rotating plate 8 drive the moving seat 9 to slide outside the long rod 11. During the sliding process, the spring 12 is squeezed, thereby converting the impact force into elastic potential energy, thereby achieving further buffering and shock absorption. The shock absorption assembly composed of the hinge seat 7, the rotating plate 8, the moving seat 9, the long rod 11, the damping rod 4 and the spring 12 can form multiple shock absorption buffers, thereby reducing the impact on the backlight source body 1 and also increasing its service life. When the backlight source body 1 needs to be inspected, the threaded sleeve 17 is rotated, and the threaded column 20 slides out of the threaded sleeve 17 under the action of its internal thread, completing the separation of the mounting plate 18 and the buffer box 2, that is, realizing the disassembly of the backlight source body 1. Similarly, during installation, the threaded column 20 is slid into the threaded sleeve 17 and rotated in the opposite direction, and the threaded column 20 enters the interior of the threaded sleeve 17 to complete the limiting and installation of the backlight source body 1.
