Description

Technical Field

[0001] This utility model relates to the technical field of display screen protection devices, and in particular to a shock-resistant and drop-proof structure for display screens. Background Technology

[0002] In existing technologies, there are many types of displays, such as liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, CRT displays, and LED displays. All types of displays contain various electronic components, making them highly susceptible to damage from impacts. In various conference venues, larger-sized displays are often used for trial purposes; some are directly fixed to the wall, while others are designed to be portable. Portable displays are another example.

[0003] A search revealed a Chinese patent application with patent number 202322049928.6, which discloses a shock-resistant and drop-proof structure for a display screen. The structure includes a drop-proof shell, an airbag groove inside the shell, a spring clip groove on the side corner of the airbag groove, a spring clip mounting bracket fixedly connected inside the spring clip groove, a spring clip fixedly mounted inside the spring clip groove via the spring clip mounting bracket, an airbag fixedly mounted inside the airbag groove, and a connecting tube on one side of the airbag.

[0004] The aforementioned patent has the following shortcomings: The device uses an airbag to protect the display screen, but in actual use, the movable display screen is installed close to the ground, the display screen itself is heavy, the landing time is fast, and the airbag inflation time is slow, which is insufficient to provide sufficient safety protection for the display screen. If the form of a car airbag is used, the instantaneous inflation of the airbag may cause the reaction force to damage the display screen, or the elasticity may be too great, causing the display screen to tilt to the other side.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] A shock-resistant and drop-proof structure for displays, such as Figures 1 to 6As shown, it includes: a display mounting shell 1 for mounting the display body 3, a limiting frame slot is formed on the inner wall of the front end of the display mounting shell 1, a display limiting frame 2 is engaged inside the limiting frame slot, a plurality of threaded holes are formed on the side wall of the limiting frame slot, and a corresponding threaded hole is formed on the side wall of the display limiting frame 2. Bolts are installed at the front end of the threaded holes and the threaded holes to fix the display limiting frame 2 inside the limiting frame slot.

[0030] A limiting support frame 16 is welded to the inner wall of the back of the display mounting shell 1. A protective rubber frame 17 is sleeved on the outer wall of the limiting support frame 16. The protective rubber frame 17 is bonded to the side wall of the display mounting shell 1, and the width of the protective rubber frame 17 is greater than the width of the limiting support frame 16.

[0031] The front end of the protective rubber frame 17 is fitted onto the outer wall of the display body 3, and its front side is in the same plane as the front side of the display body 3. The front side of the limiting support frame 16 is provided with a gap between the back side of the display body 3.

[0032] The protective rubber frame 17 is fitted onto the outer wall of the front end of the display screen body 3 and has multiple equidistant holes. Hard rubber pillars 18 are installed inside the holes. The hardness of the protective rubber frame 17 is set to 30HA, and the hardness of the hard rubber pillars 18 is set to 60HA. The two work together to improve the ability of the display screen body 3 to resist external impacts.

[0033] A rubber pressure frame 19 is provided on the front of the display body 3. The rubber pressure frame 19 is made of the same material as the protective rubber frame 17, and the rubber pressure frame 19 is fixedly installed on the back of the display limit frame 2 to protect the front of the display body 3.

[0034] The inner wall of the back of the display mounting shell 1 is integrally formed with multiple supporting connecting columns 21 at equal intervals. The outer wall of the supporting connecting columns 21 is fitted with a rubber protective sleeve 22. The main body of the rubber protective sleeve 22 is a rubber sleeve. The rubber sleeve is fitted onto the outside of the supporting connecting columns 21, and the front end of the rubber sleeve is integrally formed with a shock-absorbing rubber pad. The shock-absorbing rubber pad is attached to the back of the display body 3, and its hardness is set to 50HA.

[0035] The back of the display mounting housing 1 is provided with a mounting slot, which corresponds to the heat dissipation slot on the back of the display body 3. A mounting back plate 13 is fixedly installed on the back of the display mounting housing 1. A slot retainer is integrally formed on the front of the mounting back plate 13, and the slot retainer is engaged inside the mounting slot.

[0036] A fan mounting slot is provided in the middle of the back of the mounting back plate 13. A cooling fan 14 is fixedly installed inside the fan mounting slot. The cooling fan 14 is used to accelerate the heat dissipation of the display body 3. Multiple heat dissipation vents 15 are provided at equal intervals on both sides of the fan mounting slot to facilitate the exchange of air inside and outside the display mounting shell 1.

[0037] The display screen limiting frame 2 and the display screen mounting shell 1 work together with multiple rubber units to reduce the direct impact on the display screen body 3; and the upper parts of both sides of the display screen mounting shell 1 are fixedly connected with positioning connecting seats 4, and a rotating mounting column 5 is welded to one side of the positioning connecting seat 4, and a high-precision bearing is sleeved on the outer wall of the rotating mounting column 5.

[0038] The outer ring of the high-precision bearing is fixedly mounted with an anti-drop connecting arm 6. The bottom end of the anti-drop connecting arm 6 is provided with an installation slot. The top of the inner cavity of the installation slot is fixedly mounted with a shock absorber 20. The bottom end of the shock absorber 20 is fixedly mounted with a connecting rod 10. The bottom end of the connecting rod 10 is integrally formed with a reinforcing connector 11.

[0039] The top of the anti-fall connecting arm 6 is provided with a fixing hole, and a limiting pin 7 is fixedly installed inside the fixing hole. The limiting pin 7 extends towards the display screen mounting shell 1, and a pin limiting arc rail 8 is slidably sleeved on the outer wall of its extended end. Arc rail mounting plates 9 are welded to the outer walls of the top and bottom of the pin limiting arc rail 8. The arc rail mounting plates 9 are fixedly installed on the top of the side wall of the display screen mounting shell 1.

[0040] The connecting rod 10 is slidably installed inside the mounting slot. A friction rubber pad 12 is bonded to the outer wall of the reinforcing connector 11. The friction rubber pad 12 is used to increase the friction between the reinforcing connector 11 and the ground. The maximum acute angle between the axis of the connecting rod 10 and the front of the display mounting shell 1 is set to 70°. When the angle between the axis of the connecting rod 10 and the front of the display mounting shell 1 is equal to 50°, the bottom end of the friction rubber pad 12 will contact the ground to avoid the anti-drop connecting arm 6 from returning, which would cause the front or back of the display mounting shell 1 to fall directly to the ground.

[0041] Working principle:

[0042] Please refer to Figures 1 to 6 Assemble the device as shown in the figure;

[0043] When using this device, the back of the display screen mounting shell 1 is fixedly connected to the movable bracket, and the display screen body 3 can be moved freely.

[0044] If the device falls during the movement or installation of this device, the following situations will occur:

[0045] Scenario 1: The wide side of the display mounting shell 1 touches the ground, and the long side of the display mounting shell 1 deflects about the wide side of the display mounting shell 1 as the axis of rotation. One of the anti-drop connecting arms 6 does not deflect or deflects only slightly, while the other anti-drop connecting arm 6 deflects significantly during the deflection process. The anti-drop structure composed of the anti-drop connecting arm 6, the shock absorber 20, and the connecting rod 10 cannot support the device, but it will directly slow down the speed at which the device falls to the ground. That is, the reinforced connector 11 contacts the ground first, which reduces the deflection speed of the entire device. Due to the deflection angle limitation of the anti-drop connecting arm 6, the device will deflect again until the back or front of the entire device touches the ground. The internal components of the device (protective rubber frame 17, hard rubber column 18, rubber pressure frame 19, rubber protective sleeve 22, hereinafter collectively referred to as rubber components) will reduce the impact of direct impact on the display body 3.

[0046] Scenario 2: The bottom long side of the display mounting shell 1 touches the ground, and the wide side of the display mounting shell 1 deflects about the bottom long side of the display mounting shell 1 as the axis of rotation. Under the action of the counterweight of the reinforcing connector 11 and the center of gravity of the anti-drop connecting arm 6 itself, the two anti-drop connecting arms 6 deflect synchronously. When the angle between the axis of the connecting rod 10 and the front of the display mounting shell 1 is equal to 50°, the bottom end of the friction rubber pad 12 contacts the ground, avoiding the situation where the front or back of the display mounting shell 1 falls directly to the ground. At the same time, the shock absorber 20 reduces the impact on the anti-drop connecting arm 6 during this process.

[0047] If the corner of the display mounting housing 1 touches the ground, due to its center of gravity, it will change to situation one or situation two. During the transfer or installation of the whole device, operational requirements and habits will make the top long side of the display mounting housing 1 face upwards for ease of operation.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
