Abstract
Description
Technical Field
[0001] This invention relates to the field of display device manufacturing technology, and in particular to a high-brightness outdoor industrial LCD screen. Background Technology
[0002] High-brightness outdoor industrial LCD screens are mainly used in outdoor industrial sites and engineering equipment environments to intuitively display various monitoring data and operational information in strong light conditions, ensuring the visual control needs of industrial operations. These screens are exposed to harsh conditions such as dust and oil for extended periods, making the screen surface prone to dirt and impurities, affecting display clarity and normal equipment operation.
[0003] Currently, most traditional displays do not come with dedicated cleaning components, making manual wiping cumbersome. Some devices with simple cleaning structures can only achieve single sliding or rotating cleaning, resulting in limited movement, poor removal of stubborn stains, and blind spots in cleaning. Displays with automatic cleaning functions mostly rely on motors, sensors, and other electronically controlled components, which are not only complex and costly, but also prone to failure in outdoor high and low temperatures, humidity, and dusty environments, leading to insufficient reliability, difficult maintenance, and difficulty in meeting the long-term stable use requirements of outdoor industrial LCD screens. Summary of the Invention
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-brightness outdoor industrial LCD screen that solves the problems of blind spots in cleaning traditional outdoor screens, poor cleaning effect on stubborn stains, and complex and easy failure of the electronically controlled cleaning structure, as well as inconvenient maintenance.

[0006] According to the high-brightness outdoor industrial LCD screen of the present invention, the composite motion cleaning mechanism includes a gear and a plurality of transmission teeth; the gear is slidably fitted inside the slide groove, and the plurality of transmission teeth are equidistantly fixed to the inner wall of the slide groove and mesh with the gear.
[0007] According to the high-brightness outdoor industrial LCD screen of the present invention, the composite motion cleaning mechanism further includes a drive shaft, a turntable, and a slide rail; the drive shaft is fixedly connected to the upper surface of the gear, the turntable is fixedly connected to the upper end of the drive shaft, and the slide rail is fixedly connected to the side surface of the turntable; the brush is slidably fitted inside the slide rail.
[0008] According to the high-brightness outdoor industrial LCD screen of the present invention, the composite motion cleaning mechanism further includes a traction plate and a handle; the traction plate is rotatably fitted on the upper surface of the turntable, and the handle is fixedly connected to the upper surface of the traction plate; by holding the handle, the drive gear slides along the slide groove, causing the gear to rotate, thereby driving the brush to rotate around the axis of the traction plate.
[0009] According to the high-brightness outdoor industrial LCD screen of the present invention, the composite motion cleaning mechanism further includes a traction groove and a traction column; the traction groove is opened on the side of the traction plate facing the brush, the traction groove has a wave-shaped annular structure, and the traction column is fixed to the upper surface of the brush and slidably fitted inside the traction groove; when the brush rotates around the axis of the traction plate, the traction column slides along the traction groove, thereby driving the brush to extend, retract, and translate along the slide rail.
[0010] According to the high-brightness outdoor industrial LCD screen of the present invention, a pad is fixedly connected to the inner wall of the slide groove, and the turntable is slidably fitted onto the upper surface of the pad to ensure the smoothness of the turntable's sliding.
[0011] According to the high-brightness outdoor industrial LCD screen of the present invention, a limiting groove is formed in the inner bottom wall of the slide groove, and a roller is slidably fitted inside the limiting groove. The gear is coaxially fixed to the upper surface of the roller to ensure the smoothness of the gear movement.
[0012] Beneficial effects: This technical solution for high-brightness outdoor industrial LCD screens utilizes a composite motion cleaning mechanism. The brush rotates autonomously during sliding and, in conjunction with the traction groove and traction column, achieves synchronous telescopic and translational movement, forming a composite cleaning trajectory. Compared to a single sweeping motion, this significantly enhances the ability to remove and clean stubborn dust and stains from the screen surface. The cleaning force is more uniform and sufficient, effectively improving the cleanliness and cleaning effect of the high-brightness outdoor industrial LCD screen. Furthermore, it adopts a purely mechanical structure to achieve clean linkage, eliminating the need for motors, sensors, and other electrical control components.

[0015] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0016] Reference Figure 1-6 According to an embodiment of the present invention, a high-brightness outdoor industrial LCD screen includes: a base plate 4, a bracket 3 fixedly connected to the upper surface of the base plate 4, and an LCD screen body 2 fixedly connected to the upper end of the bracket 3. Specifically: The LCD screen body 2 is a display device that is used in outdoor and industrial scenarios, has high brightness to adapt to strong light visibility, and can withstand harsh working conditions. This is an existing mature technology that is well known to people in this field, so it will not be elaborated on in this article.
[0017] A frame 1 is fixed to the outer side of the LCD screen body 2, and a sliding groove 11 is provided on the frame 1; Considering the problem that outdoor industrial LCD screens are prone to dust accumulation and have blind spots in cleaning, a composite motion cleaning mechanism is provided in the slide 11. The composite motion cleaning mechanism is equipped with a brush 16, which slides and engages with the front surface of the LCD screen body 2. The composite motion cleaning mechanism is used to drive the brush 16 to simultaneously achieve a composite cleaning motion of rotation and telescopic sliding, so as to complete the efficient cleaning of the LCD screen body 2. This mechanism can drive the brush 16 to perform multi-dimensional cleaning actions simultaneously, thereby achieving efficient cleaning of the screen surface without dead angles and ensuring clear display under strong light; Considering the need for stable transmission and compact integration of the cleaning mechanism with the frame, the composite motion cleaning mechanism includes a gear 10 and multiple transmission teeth 12. The gear 10 is slidably fitted inside the slide groove 11, and the multiple transmission teeth 12 are equidistantly fixed to the inner wall of the slide groove 11 and mesh with the gear 10. The composite motion cleaning mechanism also includes a drive shaft 9, a turntable 7, and a slide rail 19. The drive shaft 9 is fixed to the upper surface of the gear 10, the turntable 7 is fixed to the upper end of the drive shaft 9, and the slide rail 19 is fixed to the side surface of the turntable 7. The brush 16 is slidably fitted inside the slide rail 19. When the gear 10 slides, it meshes with the transmission gear 12 and rotates, driving the turntable 7 and the brush 16 to rotate synchronously via the transmission shaft 9, making the cleaning action more continuous and uniform. Considering the problems of easy failure and inconvenience of maintenance of electronically controlled components in harsh outdoor environments, the composite motion cleaning mechanism also includes a traction plate 6 and a handle 5; the traction plate 6 is rotatably fitted on the upper surface of the turntable 7, and the handle 5 is fixed to the upper surface of the traction plate 6; by holding the handle 5, the gear 10 is driven to slide along the slide groove 11, causing the gear 10 to rotate, thereby driving the brush 16 to rotate around the axis of the traction plate 6. The operator can manually pull the entire mechanism to move via handle 5. The brush 16 can rotate and clean with pure mechanical drive. The structure is reliable and the operation is simple. Considering that rotary cleaning alone is still insufficient to remove stains from corners and edges and has limited cleaning effectiveness, the composite motion cleaning mechanism also includes a traction groove 13 and a traction column 15. The traction groove 13 is located on the side of the traction plate 6 facing the brush 16 and has a wave-shaped annular structure. The traction column 15 is fixed to the upper surface of the brush 16 and slides inside the traction groove 13. When the brush 16 rotates around the axis of the traction plate 6, the traction column 15 slides along the traction groove 13, thereby driving the brush 16 to extend, retract, and translate along the slide rail 19. When the brush 16 rotates, the traction column 15 moves along the wave-shaped traction groove 13, which can push the brush 16 to reciprocate along the slide rail 19, further eliminating cleaning dead corners and improving the cleaning effect of stubborn stains.
[0018] In summary, the improvements in this embodiment are as follows: Through the composite motion cleaning mechanism, the brush 16 rotates autonomously during sliding and works in tandem with the traction groove 13 and traction column 15 to achieve synchronous extension and translation, forming a composite cleaning trajectory. Compared with a single sweeping motion, it can significantly enhance the ability to remove and clean stubborn dust and stains on the screen surface, and the cleaning force is more uniform and sufficient, effectively improving the cleanliness and cleaning effect of the high-brightness outdoor industrial LCD screen. Furthermore, it adopts a purely mechanical structure to achieve clean linkage, eliminating the need for motors, sensors, and other electrical control components. This simplifies the structure, reduces costs, and prevents electrical components from failing in harsh industrial environments, resulting in higher reliability. It is manually driven by handle 5, making operation convenient and requiring no special tools. This facilitates on-site maintenance and reduces the difficulty of LCD screen maintenance.
[0019] Based on the above, other structures also need to be disclosed in detail, such as: A pad 8 is fixedly connected to the inner wall of the slide 11, and the turntable 7 slides on the upper surface of the pad 8 to ensure the smoothness of the slide of the turntable 7.
[0020] The inner bottom wall of the slide groove 11 is provided with a limiting groove 17, and a roller 18 is slidably fitted inside the limiting groove 17. The gear 10 is coaxially fixed to the upper surface of the roller 18 to ensure the smoothness of the movement of the gear 10.
[0021] Working principle: When the operator holds the handle 5 and pulls it along the slide groove 11 on the frame 1, it drives the turntable 7 and the gear 10 at the bottom to slide synchronously. The gear 10 moves smoothly under the support of the roller 18 in the limiting groove 17 and meshes with the transmission teeth 12 on the inner wall of the slide groove 11 to generate rotation. The gear 10 drives the turntable 7 and its side slide rail 19 and brush 16 to rotate around the axis of the transmission shaft 9 through the transmission shaft 9. At the same time, the traction plate 6 remains relatively fixed, and the traction column 15 on the brush 16 rotates with the brush 16 and slides back and forth along the wavy annular traction groove 13 on the traction plate 6, thereby pushing the brush 16 to make periodic telescopic translational movements along the slide rail 19. This allows the brush 16 to simultaneously complete the combined motion of rotational cleaning and telescopic translation during the sliding cleaning process with the overall mechanism, and to peel off and wipe the dust and stubborn stains on the surface of the LCD screen body 2 from multiple angles and in all directions. The pads 8 inside the slide 11 provide stable support for the turntable 7, reducing sliding friction and shaking. The rollers 18 and the limiting grooves 17 cooperate to prevent the gears 10 from shifting or getting stuck. The entire set of purely mechanical linkage structures can achieve thorough cleaning without the need for electrical control components, ensuring that the high-brightness outdoor industrial LCD screen always keeps the screen surface clean and clear under harsh outdoor working conditions.
[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
