Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a support structure for a display screen. Background Technology

[0002] A display screen is a device used to display images and text, and is widely used in various electronic devices such as computers, mobile phones, and televisions; while a vehicle display screen refers to a display screen specifically used in automobiles, which usually requires a support structure for installation.

[0003] Chinese utility model patent CN220262687U discloses a tilt support structure for a vehicle navigation display screen. An adjusting component rotates a bidirectional lead screw, which in turn moves two connecting seats, causing the lower end of the display screen body to move relative to the mounting frame. The display screen body then rotates along the two fixed seats, adjusting to a suitable angle for different users. However, this device causes a change in the horizontal level of the display screen's bottom when controlling its rotation. Furthermore, the rotating rod can only rotate horizontally, not vertically, affecting the stable rotation and adjustment of the display screen body, resulting in unstable tilt adjustment and support.

[0004] Therefore, there is an urgent need to improve the existing support structure of the display screen and provide a new support structure for the display screen. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a display screen support structure that is reasonably designed, simple in structure, and provides more convenient and stable tilt adjustment and support, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support structure for a display screen includes a fixed plate and a housing. The display screen body is embedded in the front end of the housing. A limiting component is installed on the rear outer wall of the housing. A bracket is fixedly installed in the middle of the fixed plate. The end of the bracket away from the fixed plate is rotatably connected to the limiting component. A stepper motor is fixedly installed on the top front outer wall of the fixed plate. A worm gear is fixedly connected to the output end of the stepper motor. Both ends of the worm gear have helical portions. Adjustable support components are provided on the right side of both helical portions. The two sets of adjustable support components are linked through the helical portions. Each adjustable support component includes an outer support rod. One end of the outer support rod is connected to a bearing of the fixed plate. A worm wheel is fixedly sleeved on the outer side of one end of the outer support rod, and the worm wheel meshes with the helical portion. A T-shaped rod is internally threaded to the other end of the outer support rod and is connected to the limiting component.

[0008] Preferably, the two sets of adjustable support components are arranged symmetrically about the bracket.

[0009] Preferably, the adjustable support assembly includes an outer support rod, a worm gear, and a T-shaped rod. One end of the outer support rod is connected to a bearing on the fixed plate, and a worm gear is fixedly sleeved on the outer side of the end of the outer support rod near the fixed plate. The other end of the outer support rod is internally threaded with a T-shaped rod.

[0010] Preferably, the two worm gears mesh with the two helical parts respectively.

[0011] Preferably, the two outer support rods rotate in the same direction.

[0012] Preferably, the threaded structures on the outer surfaces of the two T-shaped rods are arranged in opposite directions.

[0013] Preferably, the limiting component includes a fixed frame, a sliding groove, a vertical shaft, and a slider. The two fixed frames are symmetrically fixed on the side of the outer shell near the fixed plate. Sliding grooves are provided inside the upper and lower ends of the fixed frame. A vertical shaft is fixedly installed in the middle of the sliding groove. A slider is slidably sleeved on the outside of the vertical shaft. The slider is engaged and slidably located in the sliding groove.

[0014] Preferably, the front end of the T-shaped rod is hinged between the two sliders at the same horizontal level.

[0015] Preferably, one end of the bracket is connected to the fixed frame bearing, and the other end of the bracket is fixedly connected to the fixed plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this utility model, when the stepper motor is started to control the worm gear to rotate, the two worm wheels are controlled to drive the upper and lower outer support rods to rotate synchronously in the same direction by using the helical parts at both ends of the worm gear. Since the thread structure on the outer surface of the two T-shaped rods is opposite, the two T-shaped rods can be controlled to move in opposite directions with the same amplitude, which can push the slider to slide along the vertical axis, making it easy to control the outer shell and the display screen body to rotate and adjust stably.

[0018] This invention controls the sliding direction of the two T-shaped rods by controlling the rotation direction of the worm gear, thereby facilitating the control of the rotation angle of the outer shell and the display screen body. In addition, the two sets of adjustable support components can provide good support for the outer shell and the display screen body, making them more stable. Attached Figure Description

[0027] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0028] like Figure 1-5As shown in the figure, the support structure of the display screen of this utility model includes a fixed plate 1, a stepper motor 2, a housing 7, and a display screen body 8. The stepper motor 2 is fixedly installed on the outer wall of the top front end of the fixed plate 1. The output end of the stepper motor 2 is fixedly connected to a worm gear 3. Both ends of the worm gear 3 are provided with helical parts 4. Adjustable support components 6 are provided on the right side of both helical parts 4. The front end of the adjustable support component 6 is provided with a housing 7. The display screen body 8 is embedded in the front end of the housing 7. A limiting component 9 is installed on the rear outer wall of the housing 7. A bracket 5 is provided between the fixed plate 1 and the limiting component 9.

[0029] As a preferred embodiment, based on the above structure, the two sets of adjustable support components 6 are further linked by the spiral part 4, and the two sets of adjustable support components 6 are arranged symmetrically about the bracket 5.

[0030] In this embodiment, the two helical parts 4 at both ends of the worm gear 3 are used to facilitate the synchronous operation of the two sets of adjustable support components 6.

[0031] As a preferred embodiment, based on the above structure, the adjustable support assembly 6 further includes an outer support rod 61, a worm gear 62, and a T-shaped rod 63. One end of the outer support rod 61 is connected to the bearing of the fixed plate 1, and the worm gear 62 is fixedly sleeved on the outer side of the end of the outer support rod 61 near the fixed plate 1. The other end of the outer support rod 61 is internally threaded with a T-shaped rod 63.

[0032] In a preferred embodiment, based on the above structure, the two worm gears 62 mesh with the two helical parts 4 respectively, the rotation directions of the two outer support rods 61 are always the same, and the thread structure directions of the outer surfaces of the two T-shaped rods 63 are arranged in opposite directions.

[0033] In this embodiment, when the two worm gears 62 are controlled by the two helical parts 4 to drive the two outer support rods 61 to rotate synchronously in the same direction, since the thread structure on the outer surface of the two T-shaped rods 63 is opposite, the two T-shaped rods 63 can be controlled to move in opposite directions with the same amplitude, which makes it easy to control the outer shell 7 and the display screen body 8 to rotate stably.

[0034] As a preferred embodiment, based on the above structure, the limiting component 9 further includes a fixed frame 91, a sliding groove 92, a vertical shaft 93, and a slider 94. The two fixed frames 91 are fixedly installed on the side of the outer shell 7 near the fixed plate 1 and are arranged symmetrically from left to right. Sliding grooves 92 are provided inside the upper and lower ends of the fixed frame 91. The vertical shaft 93 is fixedly installed in the middle of the sliding groove 92. The slider 94 is slidably sleeved on the outside of the vertical shaft 93 and is engaged and slidably located in the sliding groove 92.

[0035] As a preferred embodiment, based on the above structure, the front end of the T-shaped rod 63 is further hinged between two sliders 94 at the same horizontal height, one end of the bracket 5 is connected to the fixed frame 91 bearing, and the other end of the bracket 5 is fixedly connected to the fixed plate 1.

[0036] In this embodiment, the vertical shaft 93 and the slider 94 slidably sleeved on its outer side are used to facilitate the sliding of the slider 94 during the extension and retraction adjustment of the T-shaped rod 63, which facilitates the stable rotation adjustment of the outer shell 7 and the display screen body 8.

[0037] The working principle of this utility model is as follows:

[0038] When it is necessary to adjust the tilt angle of the display body 8 during use, the stepper motor 2 can be started to control the worm gear 3 to rotate. The two helical parts 4 at both ends of the worm gear 3 can drive the two worm wheels 62 to drive the two outer support rods 61 to rotate synchronously in the same direction. Since the thread structure on the outer surface of the two T-shaped rods 63 is opposite, when the two outer support rods 61 rotate in the same direction, the two T-shaped rods 63 can be controlled to move in opposite directions with the same amplitude, which can push the slider 94 to slide along the vertical axis 93, so as to control the outer shell 7 and the display body 8 to rotate stably and adjust the tilt angle of the display body 8 stably.

[0039] The stepper motor 2 is electrically connected to an external power source and a terminal controller via wires. By controlling the rotation direction of the worm gear 3, the sliding direction of the two T-shaped rods 63 can be controlled, thereby facilitating the control of the rotation direction of the outer shell 7 and the display screen body 8. In addition, the two sets of adjustable support components 6 can also provide good support for the outer shell 7 and the display screen body 8.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
