Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen with a shock absorbing effect. Background Art

[0002] Liquid crystal display screens have become widely used information display devices in modern society, with application scenarios covering smart meter displays, U-shield screens, electric vehicle screens, small appliance screens, etc. However, existing liquid crystal display screens generally have poor impact resistance and are easily damaged. During transportation, installation, and use, the liquid crystal display screens are easily damaged due to factors such as vibration and impact in the external environment, affecting the display effect and even causing the equipment to be scrapped.

[0003] In order to improve the impact resistance of LCD screens, there are currently some technical solutions, such as adding internal buffer structures, but most of these buffer structures can only perform simple shock absorption, and the shock absorption effect is limited. When encountering severe bumps, the display will still be damaged.

[0004] For example, the patent specification of an existing Chinese patent (publication number: CN217880745U) discloses an easy-to-assemble, shock-resistant and buffered LCD display, including a back panel, wherein two mounting grooves are provided at the left and right ends of the back panel, and bolts are threadedly connected to the outer sides of the four mounting grooves, and a stabilizing device is fixedly connected to the upper inner plate and the lower inner plate wall of the back panel, and a mounting device is fixedly connected to the left and right front ends of the two stabilizing devices, and the front ends of the four mounting devices are commonly fixedly connected to a LCD screen body, and a plurality of function keys are fixedly connected to the lower front end of the LCD screen body, and the plurality of function keys are located above the switch key.

[0005] However, in the implementation of relevant technologies, it was found that the above-mentioned design of a liquid crystal display screen that is easy to assemble with shock-resistant buffering has the following problems: the device directly protects the display screen by installing springs and rubber pads. Although it can play a certain protective role, the shock-absorbing effect of directly using springs for shock absorption is limited. Under strong impact or vibration, it may not be able to effectively protect the display from damage.

[0006] In view of this, a liquid crystal display screen with a shock absorbing effect is provided to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a liquid crystal display screen with a shock absorbing effect.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid crystal display screen with a shock-absorbing effect, comprising a display screen body, a bottom mounting plate is arranged below the display screen body, a buffer assembly is installed on the top surface of the bottom mounting plate, the buffer assembly comprises a slide groove opened on the top surface of the bottom mounting plate, two sliding blocks are slidably arranged in the slide groove, a docking block is fixedly installed on the top end of the sliding block, a rotatable connecting rod is connected to the top end of the docking block, a resistance spring is fixedly connected between the two sliding blocks, and a damper is sleeved inside the resistance spring.

[0009] As a further description of the above technical solution: a limiting frame is integrally formed on the top surface of the bottom mounting plate, the top of the limiting frame is fixedly connected to a supporting column, the top of the supporting column is fixedly connected to a protective cover, and an upper movable plate is movably installed inside the protective cover.

[0010] As a further description of the above technical solution: a movable lower movable plate is arranged inside the bottom mounting plate, the bottom end of the lower movable plate is fixedly connected to an upper docking block, the lower movable plate is fixedly mounted on the bottom end of the display screen body, and the other end of the connecting rod is rotatably connected to the inner wall of the upper docking block.

[0011] As a further description of the above technical solution: two ends of the damper are respectively connected to two sliders.

[0012] As a further description of the above technical solution: a limiting groove is opened on the side wall of the slide groove, and a limiting block is fixedly installed on the side wall of the slider, and the limiting block can be slidably located inside the limiting groove. By setting the limiting block and the limiting groove, and setting the limiting block to be slidable inside the limiting groove, the slider is limited when moving and will not easily fall out of the slide groove, thereby increasing the stability of the device.

[0013] As a further description of the above technical solution: the movable plate is fixedly installed on the top of the display screen body, and the number of the buffer components is two groups, one group is arranged on the top of the bottom mounting plate, and the other group is arranged on the bottom of the protective cover.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model is designed to provide a liquid crystal display screen with a shock absorbing effect. A lower movable plate is fixedly connected to the bottom surface of the display screen body, and two movable sliders are arranged in a slide groove below the lower movable plate. Finally, a resistance spring and a damper are connected between the two sliders. When the display screen body is impacted, the two movable sliders cooperate with the resistance spring and the damper to reduce the impact force on the display screen body to the greatest extent, thereby making the transportation and use of the display screen body safer.

[0016] 2. The utility model designs a liquid crystal display screen with a shock-absorbing effect. By connecting an upper movable plate to the top of the display screen body, and arranging the top of the upper movable plate to be installed with the same parts as the bottom of the lower movable plate, and the bottom of the protective cover to be provided with the same parts as the top of the bottom mounting plate, the display screen body can obtain more comprehensive shock absorption, so that the display screen body will not be easily damaged during transportation and use.

The other end of the connecting rod 13 is rotatably connected to the inner wall of the upper docking block 14. The two ends of the damper 16 are respectively connected to two sliders 10. The side walls of the slide groove 8 are provided with a limiting groove 9. The side wall of the slider 10 is fixedly installed with a limiting block 11, and the limiting block 11 is slidably located inside the limiting groove 9. By setting the limiting block 11 and the limiting groove 9, and setting the limiting block 11 to be slidable inside the limiting groove 9, the slider 10 is limited when moving and will not easily escape from the slide groove 8, thereby increasing the stability of the device.

[0024] In specific implementation, during transportation or daily use, the display screen body 1 may be impacted. At this time, because the display screen body 1 is installed on the bottom surface of the lower movable plate 6, and the lower movable plate 6 is movably installed inside the bottom mounting plate 2, the display screen body 1 will press the lower movable plate 6 downward after being impacted. During the pressing process, the lower movable plate 6 will drive the connecting rod 13 downward through the upper docking block 14, and after the connecting rod 13 moves downward, the lower docking block 12 will drive the slider 10 to the two sides of the slide groove 8, and the two sliders 10 will pull the resistance spring 15 and the damper 16 during the relative movement, thereby gradually offsetting the impact force, thereby protecting the display screen body 1 from damage.

[0025] By fixing a lower movable plate 6 on the bottom surface of the display screen body 1, and arranging two movable sliders 10 in the slide groove 8 below the lower movable plate 6, and finally connecting a resistance spring 15 and a damper 16 between the two sliders 10, when the display screen body 1 is impacted, the two movable sliders 10 can cooperate with the resistance spring 15 and the damper 16 to reduce the impact force on the display screen body 1 to the greatest extent, making the transportation and use of the display screen body 1 safer.
