Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a shock-absorbing and ruggedized display screen. Background Technology

[0002] When taking public transportation, such as subways, buses, or coaches, there are screens installed inside the carriages. These screens can play public service announcements, promotional videos of the city, and some commercial advertisements, making them a very practical advertising platform.

[0003] =Because these public transportation vehicles will inevitably experience bumps and vibrations during operation, the display screen will also be subjected to vibrations during operation. This can easily cause the display screen to be damaged in a short period of time and fail to play videos normally. In severe cases, the display screen may fall and pose a significant safety hazard.

[0004] Chinese invention patent application number CN201910658206.6 describes a protective device for a display screen in rail transit. It uses a protective housing to house the display screen, employing a shock-absorbing back chamber, L-shaped rubber pads for shock absorption, and corner protectors at the four corners for shock absorption and support. A fixed frame secures the device to a wall, and hanging rods and fixing ribs ensure the stability of the protective housing, thus providing reliable shock absorption and protection for the display screen. However, this protective device occupies a significant amount of space, encroaching on the already limited space in public transportation vehicles and potentially hindering passenger movement within the carriage, thus reducing its practicality. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing and reinforced display screen to solve the problem mentioned in the background art that the existing display screen shock-absorbing protection structure occupies a large space, which may hinder the movement of passengers in the carriage and reduce the practicality of the shock-absorbing protection structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing and ruggedized display, comprising a display screen and a fixing box. A rear housing is fixedly connected to the back of the display screen. The rear housing is shaped like a frustum. A connecting block is fixedly connected to the back of the rear housing. An opening is provided on the front of the fixing box. The back of the connecting block is movably inserted into the fixing box through the opening. The left and right sides of the connecting block are respectively abutted against the left and right inner walls of the opening. The height of the connecting block is less than the height of the opening. A vertical shock-absorbing component is provided inside the fixing box. Two pairs of first shock absorbers are symmetrically fixedly connected to the top and bottom of the connecting block. The first shock absorbers are horizontally arranged. The left ends of the two pairs of first shock absorbers are connected to the front inner wall of the fixing box through a vertical sliding component. The vertical shock-absorbing component abuts against the connecting block. A first fixing rod is fixedly connected to the top of the fixing box.

[0007] Preferably, the fixing box consists of two boxes symmetrically distributed vertically, and the two boxes are fixedly connected together by bolts. The vertical sliding assembly includes two pairs of vertical plates symmetrically fixedly connected to the left ends of two pairs of first shock absorbers. Two pairs of limiting grooves are symmetrically opened on the left side of the two pairs of vertical plates. Two pairs of limiting plates are symmetrically slidably connected in the two pairs of limiting grooves. The left side of the two pairs of limiting plates is fixedly connected to the front inner wall of the two boxes respectively. The advantage of this arrangement is that it makes the connection between the fixing box and the connecting block simple and convenient, and improves the practicality of the display.

[0008] Preferably, the vertical shock absorption assembly includes two pairs of second shock absorbers symmetrically fixedly connected to the top and bottom walls of the two boxes. The second shock absorbers are not horizontally arranged, and the ends of the two pairs of second shock absorbers that are close to each other are respectively pressed against the top and bottom surfaces of the connecting block. The advantage of this arrangement is that it can effectively reduce the vibration of the display screen during the movement of the carriage, protect the safety of the display screen, and effectively extend the service life of the display screen.

[0009] Preferably, the vertical damping assembly further includes two rotating shafts symmetrically rotatably connected between the adjacent ends of the two pairs of second dampers. Two rotating rollers are symmetrically fixedly sleeved on the outer circumferential surfaces of the two rotating shafts. The outer circumferential surfaces of the two rotating rollers respectively abut against the top and bottom surfaces of the connecting block. The advantage of this arrangement is that, through the rotating shafts and rotating rollers, the second dampers can still reliably and stably abut against the connecting block during extension and retraction, ensuring that the vertical damping assembly can reliably provide vertical damping and buffering for the display screen, thereby improving the reliability and safety of the display.

[0010] Preferably, the top and bottom surfaces of the connecting block are symmetrically provided with two inclined surfaces, the distance between the two inclined surfaces gradually decreases from front to back, the two pairs of second shock absorbers are inclined and the distance between the two pairs of second shock absorbers gradually increases from front to back, and the outer peripheral surfaces of the two rotating rollers are respectively pressed against the two inclined surfaces. The advantage of this arrangement is that it can further reduce the possibility of the display screen being damaged by vibration, improve the shock absorption effect and reliability of the display, and ensure that the display can work normally in the vibrating carriage for a long time.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, by setting a connecting block and a fixing box, the connecting block is movably inserted into the fixing box. At the same time, by connecting the vertical shock-absorbing component, the first shock absorber and the vertical sliding component in the fixing box, when the display screen and the connecting block are vibrated in the carriage, the connecting block can be subjected to lateral and vertical shock absorption and buffering in the fixing box. This can effectively reduce the vibration intensity of the display screen and avoid damage to the display screen due to strong vibration, thereby improving the shock absorption effect and reliability of the display screen. In addition, the rear shell of the display screen is truncated pyramidal in shape, which can enhance the structural strength of the rear shell, thereby reinforcing the display screen and further improving the reliability and robustness of the display screen.

[0013] 2. In this utility model, by setting a vertical shock-absorbing component and two inclined planes, the pressure between the inclined planes and the rotating rollers can be increased when the display screen is subjected to vertical vibration. Under the guidance of the inclined planes, the rotating rollers can push the connecting block forward, thus converting the vertical vibration of the display screen into a back-and-forth displacement. This can further reduce the possibility of the display screen being damaged by vibration, improve the shock absorption effect and reliability of the display, and ensure that the display can work normally in the vibrating carriage for a long time.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please refer to Figures 1-6 The illustrated shock-absorbing and ruggedized display includes a display screen 1 and a mounting box 3. A rear housing 11 is fixedly connected to the back of the display screen 1. The rear housing 11 is shaped like a frustum. A connecting block 2 is fixedly connected to the back of the rear housing 11. An opening is provided on the front of the mounting box 3. The back of the connecting block 2 is movably inserted into the mounting box 3 through the opening. The left and right sides of the connecting block 2 are respectively abutted against the left and right inner walls of the opening. The height of the connecting block 2 is less than the height of the opening. A vertical shock-absorbing component 4 is provided inside the mounting box 3. Two pairs of first shock absorbers 5 are symmetrically fixedly connected to the top and bottom of the connecting block 2. The first shock absorbers 5 are horizontally arranged. The left ends of the two pairs of first shock absorbers 5 are connected to the front inner wall of the mounting box 3 through a vertical sliding component 6. The vertical shock-absorbing component 4 abuts against the connecting block 2. A first fixing rod 7 is fixedly connected to the top of the mounting box 3.

[0025] The top of the upper box 31 is symmetrically fixed with two second fixing rods 8. The two second fixing rods 8 and the first fixing rod 7 are distributed in a triangle. This can improve the connection strength between the display and the top wall of the carriage, and further improve the reliability and robustness of the display.

[0026] The first shock absorber 5 and the second shock absorber 41 are spring-damped shock absorbers.

[0027] refer to Figures 3-6 The fixed box 3 consists of two boxes 31 symmetrically distributed vertically. The two boxes 31 are fixedly connected together by bolts. The vertical sliding assembly 6 includes two pairs of vertical plates 61 symmetrically fixedly connected to the left ends of the two pairs of first shock absorbers 5. The left side of the two pairs of vertical plates 61 is symmetrically provided with two pairs of limiting grooves 62. Two pairs of limiting plates 63 are symmetrically slidably connected in the two pairs of limiting grooves 62. The left side of the two pairs of limiting plates 63 is fixedly connected to the front inner wall of the two boxes 31 respectively.

[0028] Specifically, by setting the limiting groove 62 and limiting plate 63, and cooperating with the two boxes 31 connected symmetrically, it is possible to simply insert the two pairs of limiting plates 63 into the two pairs of limiting grooves 62, and then push the two boxes 31 in the same direction until the sides of the two boxes 31 are pressed together. Then, the two boxes 31 are fixed together with bolts. This makes the connection between the fixing box 3 and the connecting block 2 simple and convenient, and improves the practicality of the display.

[0029] refer to Figures 3-6 The vertical shock absorption assembly 4 includes two pairs of second shock absorbers 41 symmetrically fixedly connected to the top and bottom walls of the two boxes 31. The second shock absorbers 41 are not horizontally arranged, and the ends of the two pairs of second shock absorbers 41 that are close to each other are respectively pressed against the top and bottom surfaces of the connecting block 2.

[0030] Specifically, the two pairs of non-horizontally arranged second shock absorbers 41 can provide vertical shock absorption and buffering for the display screen 1 through the connecting block 2. In conjunction with the horizontally arranged first shock absorber 5 and the vertical sliding component 6, the connecting block 2 can move back and forth and up and down within the fixed box 3 and obtain shock absorption and buffering. This can effectively reduce the vibration of the display screen 1 during the movement of the carriage, protect the safety of the display, and effectively extend the service life of the display.

[0031] refer to Figures 3-5 The vertical damping assembly 4 also includes two rotating shafts 42 that are symmetrically rotatably connected between the close ends of the two pairs of second dampers 41. Two rotating rollers 43 are symmetrically fixedly sleeved on the outer circumferential surfaces of the two rotating shafts 42, and the outer circumferential surfaces of the two rotating rollers 43 are respectively pressed against the top and bottom surfaces of the connecting block 2.

[0032] Specifically, the rotating shaft 42 and the rotating roller 43 enable the second shock absorber 41 to remain in stable and reliable contact with the connecting block 2 during extension and retraction, ensuring that the vertical shock absorption assembly 4 can reliably provide vertical shock absorption and buffering for the display screen 1, thereby improving the reliability and safety of the display.

[0033] refer to Figures 3-5 The top and bottom surfaces of the connecting block 2 are symmetrically provided with two inclined surfaces 21. The distance between the two inclined surfaces 21 gradually decreases from front to back. The two pairs of second shock absorbers 41 are inclined and the distance between the two pairs of second shock absorbers 41 gradually increases from front to back. The outer peripheral surfaces of the two rotating rollers 43 are respectively pressed against the two inclined surfaces 21.

[0034] Specifically, by using two inclined surfaces 21, along with two pairs of tilted second shock absorbers 41, two rotating shafts 42, and two rotating rollers 43, the pressure between the inclined surfaces 21 and the rotating rollers 43 increases when the display screen 1 is subjected to vertical vibration. Under the guidance of the inclined surfaces 21, the rotating rollers 43 can push the connecting block 2 forward, thus converting the vertical vibration of the display screen 1 into a back-and-forth displacement. This further reduces the possibility of damage to the display screen 1 due to vibration, improves the shock absorption effect and reliability of the display, and ensures that the display can work normally in a vibrating carriage for a long time.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
