Abstract
Description
Technical Field
[0001] This utility model belongs to the field of display technology, and in particular relates to a front frame of a liquid crystal display. Background Technology
[0002] The front bezel of an LCD monitor refers to the outer frame of the LCD screen, typically made of metal materials such as aluminum alloy. Its main functions include protecting the screen; as an outer protective layer, it prevents external impacts and damage, safeguarding the display from harm. However, because the front bezel is flush with the screen, it cannot effectively protect it, making the screen susceptible to contact with protrusions on the ground when it falls over. This paper proposes a structure that can provide support and protection for the monitor. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a front frame for a liquid crystal display, which solves the aforementioned problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a front frame for a liquid crystal display, comprising a front frame and a support assembly for preventing damage to the display screen; the support assembly comprises a strut, a connecting rod, a guide rod, and an anti-slip pad, wherein the connecting rod is fixedly connected to the strut, two guide rods are symmetrically slidably connected to both sides of the connecting rod, and the anti-slip pad is fixedly connected to the guide rod.
[0005] Beneficial effects
[0006] This utility model provides a front frame for a liquid crystal display, which has the following advantages compared with the prior art:
[0007] When the front frame is tilted and about to fall face-first, the user starts the motor. At this moment, the lead screw fixed to the motor output shaft begins to rotate at a constant speed. Simultaneously, the gear fixed to the lead screw begins to rotate at a constant speed, causing the gear to push a rack meshing with it. The rack then drives the sealing plate fixed to it to slide synchronously, causing the sealing plate to slide towards the side of the front frame. At this point, the sealing plate stops sealing the groove on the front frame, allowing the support rod to extend from the groove. Simultaneously, because a damping strip is provided at the connection between the sealing plate and the front frame, it effectively increases the damping of the sliding motion, preventing the sealing plate from automatically springing back to its original position without external force. At the same time, as the lead screw rotates, the threaded sliding cylinder begins to move linearly along its connection with the front frame, pushing the hinged push rod. The push rod then pushes the hinged support rod, causing it to slide towards the shaft connection. The support structure rotates upwards from the fulcrum, and before the front frame falls, the struts can form an angle of more than 10° with the front frame to increase stability during support. This is achieved by supporting the front frame with struts on both sides, preventing the display screen from directly contacting the ground and causing damage. Simultaneously, anti-slip pads increase damping with the ground, preventing movement of the anti-slip pads due to the inertial impact of the front frame tipping over. When the inertia of the front frame tipping over the struts causes relative sliding between the guide rod and the struts, the pads begin to stretch the springs fixed to them. This spring deformation provides cushioning to the struts, further preventing damage to the display screen. Additionally, the damping strips on the guide rods effectively increase the damping during sliding, allowing for smooth sliding and preventing repeated spring rebound. Attached Figure Description

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0015] Please see Figures 1-4 According to one embodiment of the present invention, a front frame of a liquid crystal display includes a front frame 101, and further includes:
[0016] Support component 2 is used to prevent damage to the display screen;
[0017] The support assembly 2 includes a strut 201, a connecting rod 202, a guide rod 203, and an anti-slip pad 204. The connecting rod 202 is fixedly connected to the strut 201, and the two guide rods 203 are symmetrically slidably connected to both sides of the connecting rod 202. The anti-slip pad 204 is fixedly connected to the guide rod 203.
[0018] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific support rod 201 described in the above embodiments. For example, the support rod 201 should be made of high-hardness steel. The purpose of this setting is to increase its load-bearing capacity through this setting, thereby avoiding it from breaking under the impact of the display and thus failing to effectively bear the load.
[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific anti-slip pad 204 described in the above embodiments. For example, the bottom surface of the anti-slip pad 204 is provided with a plurality of round dot-shaped protrusions. The purpose of this arrangement is to make its surface uneven, thereby further preventing it from sliding after grounding.
[0020] Specifically, a spring 205 is sleeved on the guide rod 203. One end of the spring 205 is fixedly connected to the connecting rod 202, and the other end of the spring 205 is fixedly connected to the pad 206. The pad 206 is fixedly connected to the guide rod 203.
[0021] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific guide rod 203 described in the above embodiments. For example, a damping rubber strip is provided at the connection between the guide rod 203 and the support rod 201. The purpose of this setting is to increase the damping of the guide rod 203 sliding on the support rod 201, so that it can slide smoothly.
[0022] Specifically, the other end of the support rod 201 is fixedly connected to a shaft 207, the shaft 207 is rotatably connected to the front frame 101, and a top rod 208 is hinged to the support rod 201.
[0023] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific top rod 208 described in the above embodiments. For example, the connection between the top rod 208 and the support rod 201 should be further hardened and reinforced. The purpose of this setting is to increase the connection stability and avoid breakage under stress.
[0024] Specifically, the other end of the top rod 208 is hinged to the slide cylinder 209, the slide cylinder 209 is slidably connected to the front frame 101, and the slide cylinder 209 is threadedly connected to the lead screw 301.
[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 301 described in the above embodiments. For example, the lead screw 301 can be a reciprocating lead screw. The purpose of this setting is that when the slider connected to it by the thread moves to one end, the sliding direction of the slider can be quickly changed by continuing to control the lead screw to rotate in the same direction.
[0026] Specifically, one end of the lead screw 301 is rotatably connected to the front frame 101, and the other end of the lead screw 301 is fixedly connected to the output shaft of the motor 302. The motor 302 is fixedly connected to the front frame 101.
[0027] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor 302 described in the above embodiments. For example, the motor 302 can be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate precise control of the sliding speed of the slide cylinder 209 so that the support rod 201 can quickly extend to provide support before the display screen is grounded.
[0028] Specifically, a gear 303 is fixedly connected to the lead screw 301, and a rack 304 is meshed with the gear 303. The rack 304 is fixedly connected to the sealing plate 305, and the sealing plate 305 is slidably connected to the front frame 101 through a groove on the front frame 101.
[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific front frame 101 described in the above embodiments. For example, a tilt sensor may be provided in the front frame 101 for starting the motor 302. When the sensor detects that the front frame 101 is tilted, the motor 302 can be started quickly.
[0030] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific spring 205 described in the above embodiments. For example, a sealing strip is provided at the connection between the spring 205 and the front frame 101. The purpose of this arrangement is to increase the sealing performance when the spring is closed.
[0031] In this embodiment of the invention, when the front frame 101 is tilted and about to fall face-first, the user starts the motor 302. At this time, the lead screw 301 fixedly connected to the output shaft of the motor 302 begins to rotate at a constant speed. Simultaneously, the gear 303 fixedly connected to the lead screw 301 begins to rotate at a constant speed, thereby causing the gear 303 to push the rack 304 meshing with it. The rack 304 then drives the sealing plate 305 fixedly connected to it to slide synchronously, causing the sealing plate 305 to slide to the side of the front frame 101. At this time, the sealing plate 305... 05. Stop sealing the groove on the front frame 101, allowing the support rod 201 to extend out of the groove in the front frame 101. Simultaneously, because the sealing plate 305 has a damping strip at the connection point with the front frame 101, the damping of its sliding is effectively increased, preventing the sealing plate 305 from automatically springing back to its original position without external force. At the same time, when the lead screw 301 rotates, the threaded slide cylinder 209 begins to move linearly along its connection point with the front frame 101, and begins to push the hinged top rod 208. At this time, the top rod 208 pushes the hinged... The support rod 201 allows it to rotate upwards around its connection point with shaft 207. Simultaneously, before the front frame 101 falls to the ground, the support rod 201 can form an angle of more than 45° with the front frame 101 to increase stability during support. This, combined with the support rods 201 on both sides of the front frame 101, prevents the display screen from directly contacting the ground and causing damage. Furthermore, the anti-slip pad 204 increases damping with the ground during this process, preventing damage from the inertial impact of the front frame 101 tipping over. When the sliding pad 204 moves and the inertia generated by the tilting of the front frame 101 is applied to the support rod 201, the guide rod 203 and the support rod 201 will slide relative to each other. This causes the pad 206 to start stretching the spring 205 that is fixedly connected to it. The spring 205 deforms to provide cushioning for the support rod 201, further preventing damage to the display screen. At the same time, the damping rubber strip on the guide rod 203 can effectively increase the damping of its sliding, allowing it to slide smoothly and preventing the spring 205 from repeatedly rebounding.
[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0033] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.
