Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, in particular to a liquid crystal display module with an anti-impact component. Background Art

[0002] To put it simply, the LCD module is a screen + backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the cathode ray tube in a CRT. Other parts include power circuits, signal processing circuits, and outer casing. The module is mainly divided into a screen and a backlight assembly. The two parts are assembled together, but they work independently of each other.

[0003] In the prior art, the existing display modules are easily impacted or jolted by external objects during transportation and installation. Both collisions and jolting will generate impact energy, which can easily cause damage to the display modules. It is necessary to add anti-impact components to buffer and absorb energy to reduce adverse effects. However, energy absorption through springs alone cannot achieve a good energy absorption effect. After being compressed by the pressure cup, the spring rebounds and resets, which will cause a reverse impact on the display body, weakening the shock-absorbing and energy-absorbing effect of the anti-impact components.

[0004] After searching, the patent with announcement number CN213545806U provides a liquid crystal display module with an anti-impact component, including a box body, a first protective component is arranged on the top of the box body, the display module is attached to the front of the inner cavity of the box body, a plate body is bolted to the back of the box body, and second protective components are fixedly installed on the upper and lower ends of the inner side of the plate body, and one end of the second protective component away from the plate body is attached to the surface of the display module, and buffer components are fixedly installed on both sides of the bottom of the inner cavity of the box body, and the top of the buffer component is bolted to the bottom of the display module. This patent realizes that the spring deforms after being subjected to force, and the deformation of the spring buffers the impact of external force and avoids direct contact with the display module, thereby achieving the purpose of anti-impact protection for the display module. However, when the collision energy is too large, the vibration amplitude of the display body is too large, resulting in excessive compression of the spring, which may cause the displacement of the spring to be too large and exceed the elastic limit of the spring itself, thereby causing the spring to fail, resulting in collision damage to the display body and the shell during subsequent transportation.

[0039] Reference Figure 4 - Figure 6 , further, the buffer mechanism also includes a connecting rod 14 and a moving rod 15, the right side of the moving rod 15 is fixedly connected with a piston plate 16, the moving rod 15 drives the piston plate 16 to move, the surface of the moving rod 15 and the surface of the sleeve 4 are connected by the connecting rod 14, the sleeve 4 moves up and down to drive the moving rod 15 to move left and right, the buffer mechanism also includes a through hole 17, the through hole 17 is opened on the surface of the piston plate 16, the piston of the piston plate 16 is installed on the inner wall of the oil cylinder 6, the shape of the piston plate 16 is cylindrical, the interior of the oil cylinder 6 is filled with oil that plays a damping role, and the oil has a strong viscosity, When the oil moves relative to the through hole 17, the oil will cause a damping effect on the movement of the piston plate 16. The moving rod 15 slides on the inner wall of the oil cylinder 6. The sliding direction of the moving rod 15 is left and right. The buffer mechanism also includes an airbag 20. The airbag 20 is fixedly mounted on the surface of the air pressure cabin 19. The material of the airbag 20 is elastic rubber material. When the airbag 20 is subjected to pressure, it will deform. The interior of the airbag 20 is connected to the inner wall of the connecting pipe 18 through the air pressure cabin 19. The interior of the air pressure cabin 19 is filled with an inert gas for transmitting pressure. The piston of the moving rod 15 is mounted on the inner wall of the connecting pipe 18.

[0040] Working principle: During use, when the protective shell 1 is subjected to bumps and collisions in the up and down directions during transportation, the display body 3 will vibrate near the equilibrium position in the up and down directions, and the display body 3 will move downward, driving the sleeve 4 to move downward. The movement of the sleeve 4 will slide up and down on the surface of the fixed rod 5. At this time, the sleeve 4 will squeeze the spring 7 to deform the spring 7 to absorb part of the vibration energy, thereby avoiding damage caused by direct collision between the display body 3 and the protective shell 1.

[0041] When the sleeve 4 moves downward, it will also drive the moving rod 15 to move leftward through the connecting rod 2 14. When the moving rod 15 moves, it will slide on the inner wall of the oil cylinder 6. When the moving rod 15 moves, it will drive the piston plate 16 to move leftward. When the piston plate 16 moves, it will squeeze the oil inside the oil cylinder 6, so that the oil pressure on the left and right sides of the piston plate 16 inside the oil cylinder 6 is different, and then the oil will flow from the side with high pressure inside the oil cylinder 6 to the side with low pressure inside the oil cylinder 6 through the through hole 17. When the oil moves relative to the through hole 17, the oil will have a damping effect on the movement of the piston plate 16, slowing down the movement speed of the piston plate 16, thereby absorbing part of the energy generated by the vibration of the display body 3, and cooperating with the spring 7 to achieve a better buffering effect.

[0042] When the sleeve 4 moves downward, it will also drive the wedge block 9 to move rightward through the connecting rod 10. When the wedge block 9 moves, it will slide on the inner surface of the frame 8. When the wedge block 9 moves to the right, it will squeeze the inclined surface of the inclined groove 13 through the inclined surface, thereby causing the limit rod 12 to move upward. When the limit rod 12 moves, it will slide on the inner wall of the cross plate 11. The limit rod 12 continues to move upward until it contacts the surface of the display body 3, thereby preventing the display body 3 from continuing to move downward, avoiding the deformation of the spring 7 too large to exceed the maximum elastic limit of the spring 7, avoiding the failure of the anti-impact component during transportation due to the failure of the spring 7, and damaging the display body 3, thereby increasing the service life of the anti-impact component.

[0043] When the sleeve 4 moves and drives the moving rod 15 to move to the left, the moving rod 15 will slide on the inner wall of the connecting tube 18. The movement of the moving rod 15 to the left will also squeeze the gas inside the connecting tube 18, thereby increasing the pressure inside the connecting tube 18, and then increasing the pressure inside the air pressure cabin 19 and the airbag 20. The increased pressure inside the airbag 20 will squeeze the airbag 20 and expand the airbag 20, thereby absorbing the collision energy of the display body 3 in the left and right directions and the front and back directions, avoiding the display body 3 from contacting the inner wall of the protective shell 1 in the left and right directions and the front and back directions during transportation, and reducing the possibility of damage to the display body 3 due to collision. At the same time, when the airbag 20 is pressurized, it will also drive the piston plate 16 to move in the reverse direction, and it also has a good absorption effect on the vibration energy of the display body 3 in the up and down directions.
