Abstract
Description
Technical Field
[0001] This utility model relates to the field of display module technology, and in particular to a small-pitch intelligent control display module. Background Technology
[0002] In today's era of rapid digital information development, display technology plays a crucial role in various fields. From large-scale commercial displays to professional control centers, from security monitoring to conference and office work, the demand for high-definition, high-reliability, and intelligent displays is increasing daily. Small-pitch intelligent control display modules, as a significant innovation in the display field, are gradually becoming core display units in numerous scenarios.
[0003] Small-pitch technology greatly improves the pixel density of the screen by continuously reducing the distance between pixels, enabling clearer and more realistic images and videos, and providing viewers with a more delicate and immersive visual experience. However, existing small-pitch display modules have significant drawbacks. For example, due to the small pixel pitch within the display module, heat dissipation needs to be considered. Traditional heat dissipation methods use fixed-position cooling fans, which can easily lead to heat dissipation dead zones. Therefore, this invention proposes a small-pitch intelligent control display module to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a small-pitch intelligent control display module.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A small-pitch intelligent control display module includes a display screen and a display module. The display module is mounted on the rear wall of the display screen. A housing is fixedly connected to the rear wall of the display screen. A heat dissipation mechanism for heat dissipation of the display screen and the display module is provided inside the housing. The heat dissipation mechanism includes a movable plate slidably connected inside the housing. A rotating rod is rotatably connected to one end of the movable plate near the display module. A fan blade is fixedly sleeved at the end of the rotating rod. A reciprocating screw is rotatably connected between the inner walls of both ends of the housing. The reciprocating screw passes through the movable plate and cooperates with it. A rotation mechanism for rotating the fan blade is provided inside the housing.
[0007] Preferably, the rotating mechanism includes a gear fixedly sleeved on the rotating rod, and a rack is fixedly connected between the inner walls of both ends of the housing, with the gear meshing with the rack.
[0008] Preferably, a back plate is provided on the rear wall of the housing.
[0009] Preferably, a motor is fixedly connected to the side wall of the housing, and the end of the output shaft of the motor is fixedly connected to the end of the reciprocating lead screw.
[0010] Preferably, a limiting rod is fixedly connected between the inner walls of both ends of the housing, and the limiting rod passes through the movable plate and is slidably connected to it.
[0011] Preferably, heat dissipation holes are provided on both ends of the housing, and a dustproof mesh is provided in each of the two heat dissipation holes.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. By setting up a heat dissipation mechanism, when dissipating heat, the output shaft of the drive motor rotates, which drives the reciprocating screw to rotate. This causes the moving plate that it works with to move back and forth within the housing. During the reciprocating movement, the rotating rod and fan blades move back and forth, which in turn drives the gear to move back and forth. The gear moves back and forth on the rack. Under the action of the rack, the gear rotates back and forth, which drives the rotating rod and fan blades to rotate back and forth. This expands the airflow range of the fan blades, thereby improving the heat dissipation effect and avoiding heat dissipation dead zones.
[0014] 2. By setting a rack and pinion, the gear moves back and forth on the rack, driving the gear to rotate back and forth, which in turn drives the fan blades to rotate back and forth. The forward rotation of the fan blades can blow out the hot air inside the housing, and the reverse rotation of the fan blades can draw in the air outside the housing, thereby achieving better heat dissipation for the display module and improving the practicality of the device.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0022] Reference Figure 1-5 A small-pitch intelligent control display module includes a display screen 1 and a display module 14. The display module 14 is mounted on the rear wall of the display screen 1. A housing 2 is fixedly connected to the rear wall of the display screen 1. The housing 2 is provided with a heat dissipation mechanism for heat dissipation of the display screen 1 and the display module 14. The heat dissipation mechanism includes a movable plate 9 slidably connected inside the housing 2. A rotating rod 12 is rotatably connected to one end of the movable plate 9 near the display module 14. A fan blade 11 is fixedly sleeved at the end of the rotating rod 12. A reciprocating screw 7 is rotatably connected between the inner walls of both ends of the housing 2. The reciprocating screw 7 passes through the movable plate 9 and cooperates with it. A motor 4 is fixedly connected to the side wall of the housing 2. The end of the output shaft of the motor 4 is fixedly connected to the end of the reciprocating screw 7.
[0023] Specifically, the housing 2 is provided with a rotating mechanism for rotating the fan blade 11. The rotating mechanism includes a gear 10 fixedly sleeved on the rotating rod 12. A rack 8 is fixedly connected between the inner walls of both ends of the housing 2. The gear 10 meshes with the rack 8.
[0024] Specifically, a back plate 6 is provided on the rear wall of the housing 2, and a limit rod 13 is fixedly connected between the inner walls of both ends of the housing 2. The limit rod 13 passes through the movable plate 9 and is slidably connected to it. The limit rod 13 is set horizontally, which can limit the movable plate 9 and improve the stability of the movement of the movable plate 9. Multiple wiring holes are provided on the back plate 6, through which connecting wires can be passed and connected to the display module 14.
[0025] Specifically, heat dissipation holes 3 are provided on both ends of the side wall of the housing 2, and dustproof mesh 5 is provided in both heat dissipation holes 3. The dustproof mesh 5 can prevent dust from entering the housing 2 and prevent the display module 14 from being displayed.
[0026] When this utility model is in use, during heat dissipation, the output shaft of the drive motor 4 rotates, driving the reciprocating screw 7 to rotate, which in turn drives the movable plate 9 to reciprocate within the housing 2. During the reciprocating movement, the rotating rod 12 and the fan blade 11 reciprocate, driving the gear 10 to reciprocate. The gear 10 reciprocates on the rack 8. Under the action of the rack 8, the gear 10 reciprocates, driving the rotating rod 12 and the fan blade 11 to reciprocate, which expands the airflow range of the fan blade 11, thereby improving the heat dissipation effect and avoiding heat dissipation dead zones. The reciprocating movement of the gear 10 on the rack 8 drives the fan blade 11 to reciprocate. The forward rotation of the fan blade 11 blows out the hot air inside the housing 2, while the reverse rotation of the fan blade 11 draws in the air outside the housing 2, achieving better heat dissipation for the display module 14.
[0027] 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.
