DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figures 1 to 4The structure of an impact-resistant LCD display screen frame shown in the figure includes a fixed base 1 and a stabilizing frame 2, a protective frame 3 is installed on the front side of the stabilizing frame 2, a mounting groove 4 is opened on the upper part of the stabilizing frame 2, a resisting block 6 is connected to the mounting groove 4 through a mounting rod 5, a slide rail 7 is embedded and installed on the left and right sides of the resisting block 6, a slide rod 8 is movably arranged in the slide rail 7, a hinge seat 9 is symmetrically arranged on the top of the rear side of the protective frame 3, and the rear side of the hinge seat 9 is connected to the slide rod 8 by a rotating connecting rod 10; two through shafts 11 are arranged on the inner side of the connecting rod 10, and the through shaft 11 is rotatably connected to the slide rod 8; an elastic plate 12 is symmetrically arranged on the top of the rear side of the protective frame 3; a pressure dividing plate 13 is arranged on the rear side of the connecting rod 10, and the pressure dividing plate 13 is located on the rear side of the elastic plate 12; a first air bag 14 and a second air bag 15 are arranged on the top of the rear side of the protective frame 3; the first air bag 14 and the second air bag 15 are both located on the front side of the mounting rod 5; a rubber strip 16 is arranged on the inner wall of the front side of the protective frame 3.

[0021] When the protective frame 3 receives an external impact force, the corresponding side or the whole will be offset backwards, and the corresponding hinge seat 9 will move backwards to drive the connecting rod 10 to swing, and then the sliding rod 8 is forced to move inward on the sliding rail 7, so that the impact force on the protective frame 3 is delayed and weakened, thereby protecting the liquid crystal display screen installed on the inner wall; at the same time, an angled elastic plate 12 is arranged between the connecting rod 10 and the protective frame 3. When the protective frame 3 receives an external impact force, the elastic plate 12 bends to relieve and disperse the force transmitted by the connecting rod 10 to a certain extent, thereby achieving a better anti-impact effect; an air bag is also arranged on the rear side of the protective frame 3 and in front of the two mounting rods 5, which indirectly reduces the effect of the impact force on the protective frame 3 and effectively protects the liquid crystal display screen arranged therein.

[0022] Example 2

[0023] like Figures 1 to 4 The illustrated structure is an impact-resistant frame structure for a liquid crystal display screen, comprising a fixed base 1 and a stabilizing frame 2. The fixed base 1 is installed on a plane by means of fasteners such as bolts, and the stabilizing frame 2 is installed on the top front side of the fixed base 1 by means of a triangular structure connection, for supporting and stabilizing the installation of the liquid crystal display screen; a protective frame 3 is installed on the bottom front side of the stabilizing frame 2 by means of fasteners, the protective frame 3 is a hollow structure, the front side of the inner wall can be used to install the liquid crystal display screen, and a rubber strip 16 installed on the inner wall of the protective frame 3 can reduce the hard contact between the protective frame 3 and the liquid crystal display screen, thereby performing a simple protective action on the liquid crystal display screen; at the same time, a space is provided on the outside of the protective frame 3 to isolate the liquid crystal display screen from direct contact with external forces, thereby further realizing the protective action.

[0024] Among them, the protective frame 3 can be made of high-strength, impact-resistant materials, such as polycarbonate, magnesium alloy, etc. These materials have good impact resistance and can effectively reduce the deformation and damage of the LCD screen caused by the protective frame 3 when it receives external impact.

[0025] Example 3

[0026] like Figures 1 to 4 An impact-resistant LCD frame structure is shown, in which a protective frame 3 is installed on the front side of the bottom of a stabilizing frame 2 by fasteners, and the protective frame 3 is used to install the LCD and provide basic protection for it; at the same time, an anti-impact component is arranged between the top rear side of the protective frame 3 and the stabilizing frame 2 to achieve better protection for the LCD.

[0027] The upper part of the stabilizing frame 2 is provided with a mounting groove 4, and a resisting block 6 is connected to the mounting groove 4 through a mounting rod 5. The mounting rod 5 is respectively located on the left and right sides of the mounting groove 4 and is located at the diagonal position of the resisting block 6. The resisting block 6 can be firmly installed on the stabilizing frame 2, thereby realizing the dual connection of the upper and lower parts of the protective frame 3 and the liquid crystal display screen. The left and right sides of the resisting block 6 are embedded with slide rails 7, and a slide bar 8 is movably arranged in the slide rail 7, that is, the slide bar 8 can move left and right in the slide rail 7 and can also rotate; the top rear side of the protective frame 3 is symmetrically provided with an articulated seat 9, and the inner side of the articulated seat 9 is rotatably provided with a connecting rod 10, and the connecting rod 10 is divided into an upper and lower branch after extending inward, and the upper and lower branches are provided with a through shaft 11, and the through shaft 11 is respectively sleeved on the upper and lower parts of the slide bar 8 and is rotatably connected with the slide bar 8. It can be obtained that when the protective frame 3 receives an external impact force, the corresponding side or the whole will be offset backwards, and the corresponding hinge seat 9 will move backwards to drive the connecting rod 10 to swing, and then the sliding rod 8 is forced to move inward on the sliding rail 7, delaying and weakening the impact force on the protective frame 3, thereby protecting the LCD screen installed on the inner wall.

[0028] Example 4

[0029] Referring to the contents in Example 3, when the protective frame 3 receives impact force, the impact force will be dispersed and weakened through the connection between the slide bar 8 and the slide rail 7, thereby achieving effective anti-impact performance; however, considering that the connection between the slide bar 8 and the slide rail 7 is also a rigid connection, and the protective frame 3 needs to be manually reset later, which is troublesome, an angled elastic plate 12 is installed at the position located in front of the connecting rod 10 and on the protective frame 3, with the angle aligned with the direction of the hinge seat 9, and the pop-up angle is flush with the initial angle of the connecting rod 10; then, under the influence of the material of the elastic plate 12, the elastic plate 12 can always resist the connecting rod 10 and maintain a straight state with the slide bar 8, avoiding the occurrence of accidental touches caused by inadvertent touches. When the protective frame 3 receives a strong impact force, the elastic plate 12 bends, which can alleviate and disperse the force transmitted by the connecting rod 10 to a certain extent, achieving a better anti-impact effect, and also avoiding damage to the anti-impact component.

[0030] In order to enable the elastic plate 12 to achieve a more effective buffering effect, a pressure dividing plate 13 is specially provided on the front side of the connecting rod 10, that is, the pressure dividing plate 13 is located on the rear side of the elastic plate 12, sandwiched between the connecting rod 10 and the elastic plate 12, and the width of the pressure dividing plate 13 is greater than the elastic plate 12, so that the force on the connecting rod 10 can first be dispersed to a certain extent through the pressure dividing plate 13, and then further buffered by the elastic plate 12; at the same time, the width of the pressure dividing plate 13 is greater than the elastic plate 12, which can also prevent the connecting rod 10 from directly colliding with the elastic plate 12 when subjected to force, thereby causing damage to the relatively narrow connecting rod 10, thereby ensuring the performance of the anti-impact component.

[0031] Example 5

[0032] like Figures 1 to 4 The impact-resistant frame structure of a liquid crystal display screen shown in the figure is also provided with a first airbag 14 and a second airbag 15 at the rear side of the protective frame 3 and at the front side of the two mounting rods 5. When the liquid crystal display screen receives an impact force, the mounting rods 5 are subjected to a fixed-direction squeezing force, which is buffered by the airbags. As the impact force increases, the airbags begin to deform, and the internal gas of the airbags gradually flows out through a preset channel to form a buffer zone for gas flow. In the whole process, the effect of the impact force on the protective frame 3 is indirectly mitigated, and the liquid crystal display screen provided therein is effectively protected.
