Description

Technical Field

[0001] This invention relates to the field of anti-vibration liquid crystal display technology, specifically to an anti-vibration liquid crystal display. Background Technology

[0002] Liquid crystal displays (LCDs) have advantages such as small size, light weight, low power consumption, low electromagnetic radiation, and immunity to magnetic field interference. They are widely used in many fields, such as industrial control, medical equipment, military equipment, transportation, and everyday devices such as televisions, computers, and mobile phones. When an LCD screen is subjected to external impact, the external impact force will directly contact the surface of the casing, thereby generating vibration and affecting the overall device.

[0003] A shock-resistant LCD display, patent publication number CN222559575U, includes a housing with an internal shock-resistant mechanism. This mechanism comprises a connecting U-shaped slider, a shock-absorbing spring, and a damper. A buffer groove is formed inside the housing, and the front of the connecting U-shaped slider is slidably connected to the inside of the buffer groove. This shock-resistant LCD display, through the use of a buffer protrusion structure, allows the buffer protrusion to move inwards from the housing when subjected to external impact, thus preventing direct contact between the external impact force and the housing surface, reducing the impact on the overall device. The use of connecting blocks, connecting shafts, and steering blocks effectively solves the problem of more efficient shock absorption in practice, achieving a more efficient and safer use and preventing damage to the display and the entire device. However, the shock-resistant mechanism of the aforementioned anti-vibration LCD screen cannot provide comprehensive protection for its casing. When the side of the casing of the device is directly impacted, the shock-resistant device may not be activated to effectively protect the casing, resulting in damage to the casing or the display screen from direct impact force. Summary of the Invention

[0009] According to the above technical solution, the upper end of the support plate is hinged to the side wall of the hinge block, and the torsion spring is fixedly connected to the hinge point between the support plate and the hinge block. One end of the torsion spring is fixedly connected to the support plate, and the other end of the torsion spring is fixedly connected to the hinge block. The torsion spring is stretched when the support plate rotates.

[0010] According to the above technical solution, the shock absorption device includes a fixed rod, a connecting block, a hinge rod, and a rubber block. The fixed rod is fixedly connected to the side wall of the slide rail. The fixed rod passes through the connecting block and is slidably connected at the point of penetration. When the hinge block slides downward, it drives the connecting block to slide towards the slide rail.

[0011] According to the above technical solution, the upper end of the hinge rod is hinged to the bottom surface of the connecting block, and the end of the hinge rod away from the connecting block is hinged to the upper surface of the hinge block. The rubber block is fixedly connected to the side wall of the connecting block. When the connecting block slides, it drives the rubber block to move and move closer to each other.

[0012] According to the above technical solution, the protection device includes an air storage chamber, a safety airbag, a compression block, and a sealing plate.

[0014] This invention provides a shock-resistant liquid crystal display screen. It has the following beneficial effects: (1) The present invention is equipped with a protective device. When the LCD screen is subjected to an impact force, its outer shell will drive the sliding block to slide along the inner wall of the slide rail. At the same time, it will cooperate with the buffer spring to use the elastic potential energy of the buffer spring to offset the impact force on the LCD screen, thereby reducing the impact force on the LCD screen and preventing the LCD screen and the shell from directly bearing all the impact force and causing damage. This solves the problem that the LCD screen is easy to break off from the support frame when it is impacted. When the LCD screen drives the sliding block to move, it also drives the trapezoidal block to slide. With the help of the guide rod, hinge block, reset spring, moving block and torsion spring, the support plate moves downward and rotates at the same time, so that the two sets of support plates form a more stable triangle on the bottom surface of the slide rail, supporting the support frame and the slide rail. This further stabilizes and supports the support frame and the slide rail, solving the problem that the support frame is unevenly stressed and easy to tip over when the LCD screen is impacted.

[0015] (2) The present invention is equipped with a shock absorption device. When the LCD screen is impacted, the hinge block moves downward to drive the hinge rod to rotate. The hinge rod drives the two sets of connecting blocks to move closer to each other. The rubber block clamps the LCD screen and the housing between the two sets of connecting blocks, reducing the range of motion of the LCD screen and the housing, thereby reducing the vibration amplitude of the LCD screen and the housing. This solves the problem that the LCD screen and the housing vibrate when impacted, which can easily cause the connection to loosen and the equipment to be damaged.

[0016] (3) The present invention is equipped with a protective device. After the LCD screen or the housing is impacted, the connecting block pushes the squeezing block to slide, so that the sealing plate pushes the air in the air storage chamber into the safety airbag. The inflated safety airbag protects the front and back of the LCD screen and the housing, thereby preventing the LCD screen from being damaged by secondary impacts and solving the problem that the LCD screen is easily damaged when it is knocked over.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6 One embodiment of the present invention is as follows: a shock-resistant liquid crystal display screen includes a liquid crystal screen 1 and a support frame 5. The support frame 5 is disposed at the bottom of the liquid crystal screen 1. A housing 2 is fixed to the outer wall of the liquid crystal screen 1. A protective pad is fixed to the outer wall of the housing 2. A heat dissipation hole 3 is provided on the side wall of the housing 2. A slide rail 4 is fixed to the upper surface of the support frame 5. A protective device is provided on the inner wall of the slide rail 4 to prevent the liquid crystal screen 1 from falling off when it is impacted.

[0021] The protective device includes a fixed plate 61, a buffer spring 62, a sliding block 63, a trapezoidal block 64, a guide rod 65, a hinge block 66, a return spring 67, a moving block 68, a support plate 69, and a torsion spring 610. The fixed plate 61 is fixedly connected to the inner wall of the slide rail 4. One end of the buffer spring 62 is fixedly connected to the side wall of the fixed plate 61. The sliding block 63 is fixedly connected to the bottom surface of the housing 2. The outer wall of the sliding block 63 is slidably connected to the inner wall of the slide rail 4. When the LCD screen 1 is impacted, the LCD screen 1 will drive the sliding block 63 to slide along the slide rail 4. The other end of the buffer spring 62 is fixedly connected to the side wall of the sliding block 63. When the sliding block 63 slides, the buffer springs 62 on both sides of the fixed plate 61 are subjected to force, respectively compressing and... The stretching and buffering spring 62 reduces the impact force on the LCD screen 1. The trapezoidal block 64 is fixedly connected to the side of the sliding block 63 away from the buffering spring 62. When the sliding block 63 slides, it also drives the trapezoidal block 64 to slide together. The guide rod 65 is fixedly connected to the bottom surface of the slide rail 4. The guide rod 65 passes through the hinge block 66 and is slidably connected at the point of penetration. The return spring 67 is fixedly connected to the bottom surface of the hinge block 66. The end of the return spring 67 away from the hinge block 66 is attached to the placement surface. When the hinge block 66 slides downward, it compresses the return spring 67. The moving block 68 is fixedly connected to the upper surface of the hinge block 66. The side wall of the moving block 68 is slidably connected to the side end of the slide rail 4. When the trapezoidal block 64 slides to the moving block 68, the trapezoidal block 64... The inclined surface of trapezoidal block 64 is slidably connected to the side of movable block 68. As trapezoidal block 64 continues to slide, it pushes movable block 68 downward. When movable block 68 slides downward, it causes hinge block 66 to slide downward along guide rod 65. The upper end of support plate 69 is hinged to the side wall of hinge block 66. When hinge block 66 slides downward, it also causes the hinge point between hinge block 66 and support plate 69 to move downward. Since the bottom end of support plate 69 is in contact with the placement surface, the bottom end of support plate 69 does not change position in the vertical direction. Therefore, when the upper end of support plate 69 moves downward, support plate 69 also rotates. Torsion spring 610 is fixedly connected to the hinge point between support plate 69 and hinge block 66, and one end of torsion spring 610 is fixedly connected to support plate 69. The other end of the torsion spring 610 is fixedly connected to the hinge block 66. The support plate 69 rotates to stretch the torsion spring 610. As the two sets of support plates 69 rotate, the distance between their bottom ends increases, so that the two sets of support plates 69 and the placement surface form a triangle to support the slide rail 4. When the LCD screen 1 is subjected to an impact force, the outer shell 2 of this protective device will drive the sliding block 63 to slide along the inner wall of the slide rail 4. At the same time, in conjunction with the buffer spring 62, the elastic potential energy of the buffer spring 62 is used to offset the impact force on the LCD screen 1, thereby reducing the impact force on the LCD screen 1 and preventing the LCD screen 1 and the shell 2 from directly bearing all the impact force and causing damage. This solves the problem that the LCD screen 1 is easy to break off from the support frame 5 when it is impacted.When the LCD screen 1 moves the sliding block 63, it also moves the trapezoidal block 64. In conjunction with the guide rod 65, hinge block 66, return spring 67, moving block 68, and torsion spring 610, the support plate 69 moves downwards and rotates simultaneously. This causes the two sets of support plates 69 to form a more stable triangle on the bottom surface of the slide rail 4, supporting the support frame 5 and the slide rail 4. This further stabilizes and supports the support frame 5 and the slide rail 4, solving the problem of uneven force distribution on the support frame 5 and easy tipping when the LCD screen 1 is impacted.

[0022] In this embodiment, when the LCD screen 1 is impacted, the LCD screen 1 will cause the sliding block 63 to slide along the slide rail 4. When the sliding block 63 slides, the buffer springs 62 on both sides of the fixed plate 61 are subjected to force, which is squeezed and stretched respectively. The buffer springs 62 reduce the impact force on the LCD screen 1. While the sliding block 63 slides, it also causes the trapezoidal block 64 to slide together. When the trapezoidal block 64 slides to the moving block 68, the inclined surface of the trapezoidal block 64 slides and connects with the side of the moving block 68. The trapezoidal block 64 continues to slide, pushing the moving block 68 to slide downward. When the moving block 68 slides downward, it causes the hinge block 66 to slide downward along the guide rod 65. When the hinge block 66 slides downward, it compresses the reset spring 67. When the hinge block 66 slides downward, it also causes the hinge point between the hinge block 66 and the support plate 69 to move downward. The bottom end of the support plate 69 Since the support plate 69 is in contact with the placement surface, its bottom position in the vertical direction remains unchanged. Therefore, when the upper end of the support plate 69 moves downward, the support plate 69 also rotates. The rotation of the support plate 69 stretches the torsion spring 610. As the two sets of support plates 69 rotate, the distance between their bottom ends increases, forming a triangle between the two sets of support plates 69 and the placement surface, supporting the slide rail 4. When the impact force on the LCD screen 1 disappears, the sliding block 63 is reset by the elastic force of the two sets of buffer springs 62, and at the same time, it drives the trapezoidal block 64 to reset. The moving block 68 is no longer pushed by the trapezoidal block 64, and at the same time, it is pushed by the reset spring 67 on the hinge block 66, and slides upward. The upward sliding of the hinge block 66 drives the hinge point between the support plate 69 and the hinge block 66 to move upward. At the same time, the upper end of the support plate 69 moves upward, and the torsion spring 610 returns to its original state, driving the support plate 69 to reset.

[0023] Please see Figures 1-6Based on the above embodiments, in another embodiment of the present invention, the side wall of the slide rail 4 is provided with a shock-absorbing device to facilitate the stabilization of the LCD screen 1. The shock-absorbing device includes a fixed rod 71, a connecting block 72, a hinge rod 73, and a rubber block 74. The fixed rod 71 is fixedly connected to the side wall of the slide rail 4, and the fixed rod 71 passes through the connecting block 72 and is slidably connected at the point of penetration. The upper end of the hinge rod 73 is hinged to the bottom surface of the connecting block 72, and the end of the hinge rod 73 away from the connecting block 72 is hinged to the upper surface of the hinge block 66. When the hinge block 66 slides downward, it also drives the hinge point between the hinge rod 73 and the hinge block 66 to move downward. The end of the hinge rod 73 away from the hinge block 66 is hinged to the bottom surface of the connecting block 72, and the connecting block 72 can only slide along the fixed rod 71. Therefore, the position of the hinge point between the hinge rod 73 and the connecting block 72 remains unchanged in the vertical direction. When the bottom end of the hinge rod 73 moves downward... When the device moves downwards, the hinge rod 73 also rotates, causing the connecting block 72 to slide towards the slide rail 4. The rubber block 74 is fixedly connected to the side wall of the connecting block 72. When the connecting block 72 slides, it causes the rubber block 74 to move. The two sets of connecting blocks 72 and the rubber block 74 move closer to each other, clamping the housing 2 in the center and stabilizing the housing 2, thus reducing the vibration amplitude of the LCD screen 1 and the housing 2. When the LCD screen 1 is impacted, the device causes the hinge rod 73 to rotate through the downward-moving hinge block 66. The hinge rod 73 causes the two sets of connecting blocks 72 to move closer to each other, and together with the rubber block 74, clamps the LCD screen 1 and the housing 2 between the two sets of connecting blocks 72, reducing the range of motion of the LCD screen 1 and the housing 2, thereby reducing the vibration amplitude of the LCD screen 1 and the housing 2. This solves the problem that when the LCD screen 1 and the housing 2 are impacted, the vibration can easily cause the connection to loosen and damage the equipment.

[0024] The outer wall of the slide rail 4 is equipped with a protective device to prevent secondary impacts from both the front and rear. The protective device includes an air reservoir 81, an airbag 82, a compression block 83, and a sealing plate 84. The air reservoir 81 is fixedly connected to the side wall of the slide rail 4, and the airbag 82 is also fixedly connected to the side wall of the slide rail 4, communicating with the air reservoir 81. The compression block 83 is slidably connected to the side wall of the slide rail 4, penetrating the air reservoir 81, and slidably connected at the penetration point. When the connecting block 72 slides towards the slide rail 4 to the compression block 83, the inclined surface of the compression block 83 slidably connects with the inclined side of the connecting block 72. The connecting block 72 continues to slide, pushing the compression block 83 towards the air reservoir 81. The sealing plate 84 is fixedly connected to the end of the compression block 83 away from the connecting block 72. The outer wall of the sealing plate 84 is attached to the inner wall of the air storage chamber 81. When the extrusion block 83 slides, it pushes the sealing plate 84 against the inner wall of the air storage chamber 81 towards the airbag 82, squeezing the air in the air storage chamber 81 into the airbag 82, causing the airbag 82 to inflate and protect the front and back sides of the LCD screen 1. After the LCD screen 1 or the housing 2 is impacted, the protective device pushes the extrusion block 83 to slide through the connecting block 72, causing the sealing plate 84 to push the air in the air storage chamber 81 into the airbag 82. The inflated airbag 82 protects the front and back sides of the LCD screen 1 and the housing 2, thereby preventing the LCD screen 1 from being damaged by secondary impacts and solving the problem that the LCD screen 1 is easily damaged when it is knocked over.

[0025] In this embodiment, when the hinge block 66 slides downward, it also drives the hinge point between the hinge rod 73 and the hinge block 66 to move downward. The end of the hinge rod 73 away from the hinge block 66 is hinged to the bottom surface of the connecting block 72. The connecting block 72 can only slide along the fixed rod 71. Therefore, the position of the hinge point between the hinge rod 73 and the connecting block 72 remains unchanged in the vertical direction. When the bottom end of the hinge rod 73 moves downward, the hinge rod 73 also rotates, driving the connecting block 72 to slide in the direction of the slide rail 4. When the connecting block 72 slides, it drives the rubber block 74 to move. The two sets of connecting blocks 72 drive the rubber block 74 to move closer to each other, clamping the housing 2 in the center, stabilizing the housing 2, and reducing the vibration amplitude of the LCD screen 1 and the housing 2. When the hinge block 66 is reset by the elastic force of the reset spring 67, the hinge block 66 pushes the hinge rod 73 to rotate in the opposite direction, causing the connecting block 72 to drive the rubber block 74 to move away from the housing 2 and the LCD screen 1.

[0026] When the connecting block 72 slides towards the slide rail 4 to the pressing block 83, the inclined surface of the pressing block 83 slides and connects with the inclined side of the connecting block 72. The connecting block 72 continues to slide, pushing the pressing block 83 towards the air storage chamber 81. When the pressing block 83 slides, it pushes the sealing plate 84 to slide against the inner wall of the air storage chamber 81 towards the airbag 82, squeezing the air in the air storage chamber 81 into the airbag 82, causing the airbag 82 to inflate and protect the front and back sides of the LCD screen 1. When the user confirms that the LCD screen 1 will not be damaged by impact or other hazards again, he / she manually pushes the pressing block 83 away from the air storage chamber 81. When the pressing block 83 slides away from the air storage chamber 81, it drives the sealing plate 84 to slide away from the airbag 82, extracting the air from the airbag 82 and restoring it to its original state.
