Description

Technical Field

[0001] This invention belongs to the field of touch display, specifically relating to a movable cover plate that can cover a display module. Background Technology

[0002] With the widespread adoption of smart electronic devices (such as smartphones, tablets, and in-vehicle infotainment terminals), display modules, as core interactive components, face higher demands on the protective performance, optical performance, and structural adaptability of their external cover plates. Existing display structures mostly employ fixed glass cover plates, which are structurally simple, functionally limited, and unable to simultaneously meet the multiple needs of display protection, aesthetic appeal, and functional expansion.

[0003] First, existing cover plates are usually fixed structures, lacking dynamic opening or closing functions. Once the device is in standby or non-use mode, the screen is susceptible to external damage such as scratches, contamination, or impacts, especially outdoors or in complex environments. Although some high-end products have attempted to introduce sliding or flip-top structures, their complex structures, difficult manufacturing, poor reliability, and susceptibility to failure make it difficult to achieve widespread industrial application.

[0004] Secondly, in terms of material selection and functional design of display cover plates, existing technologies mostly use single-material glass or plastic, resulting in limited functionality. There is a lack of material systems that integrate multiple functions such as wear resistance, scratch resistance, light transmission, and electromagnetic shielding into the same cover plate. Furthermore, interactive designs such as temperature sensing are not reasonably implemented on the glass cover plate, leading to a lack of novelty and practicality in the user experience.

[0005] Furthermore, the surface structure of existing glass covers typically lacks systematic coating or screen printing treatment, providing only basic protective functions and failing to fully utilize the potential of the materials themselves or achieve effective synergy between performance components. For example, although materials such as titanium nitride, graphene, and magnesium fluoride are known to possess excellent properties in other technological fields, their composite application in the field of glass covers is still in the exploratory stage, lacking mature structural integration methods.

[0006] Therefore, existing technologies generally suffer from the following problems that urgently need to be addressed: The cover plate structure has a single function, lacks mobility and structural locking mechanisms, and is difficult to achieve dynamic protection of the display screen; The cover material and structure lack composite design, failing to integrate multiple functions such as high light transmittance, high hardness, wear resistance, electromagnetic shielding and temperature sensing in the same cover. Existing glass covers fail to effectively combine functional film layers with screen-printed structures, resulting in insufficient overall aesthetics, practicality, and integration capabilities. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a movable cover plate structure that can cover the display module to achieve dynamic protection of the display screen.

[0008] To solve the above-mentioned technical problems, the technical method adopted by the present invention is as follows: The present invention discloses a movable cover plate that can cover a display module, including a cover plate body that can accommodate the display module and a sliding cover plate; the sliding cover plate includes a left sliding cover plate and a right sliding cover plate; The center of the cover plate body is provided with a display screen display area; on both sides of the display screen display area, a left sliding cover plate and a right sliding cover plate are symmetrically arranged. The left and right sliding covers can reciprocate relative to the display screen's display area. When the left and right sliding covers come into contact, they can completely cover the area above the display screen's display area. When the left and right sliding covers are relatively far apart, the area above the display screen can be fully exposed.

[0009] Furthermore, the cover plate body is provided with a cover plate groove that provides guidance and limitation for the sliding cover plate.

[0010] Furthermore, the left sliding cover and the right sliding cover have the same structure, including a sliding base plate and a buckle disposed on the sliding base plate; The cover plate body is provided with locking teeth that match the buckle.

[0011] Furthermore, the locking teeth include an inclined surface and a limiting surface; The front end of the buckle is provided with a guide portion; the guide portion includes a guide surface that matches the inclined surface and a buckle tail section that can be fixed with the limiting surface; When the left sliding cover and the right sliding cover come into contact, the end of the latch contacts the limiting surface, locking the sliding cover so that it cannot move away.

[0012] Furthermore, the buckle is made of an elastic material.

[0013] Furthermore, the cover plate body is a glass cover plate, and the front side of the glass cover plate is provided with a magnesium fluoride layer, a graphene layer and a titanium nitride layer from top to bottom, and the titanium nitride layer is directly coated on the upper surface of the glass cover plate.

[0014] Furthermore, the thickness of the magnesium fluoride layer is 5 nanometers to 10 nanometers, the thickness of the graphene layer is 20 nanometers to 30 nanometers, and the thickness of the titanium nitride layer is 5 nanometers to 10 nanometers.

[0015] Furthermore, a thermochromic ink layer is provided on the back edge area of ​​the glass cover, and a metal protective layer is provided below the thermochromic ink layer.

[0016] Furthermore, the thickness of the thermochromic ink layer is 8 to 10 micrometers, and the metal protective layer is a chromium layer with a thickness of 5 to 8 micrometers.

[0017] Furthermore, the left and right sliding covers are provided with rubber anti-collision sealing strips on the side near the display screen's image area.

[0018] Beneficial effects: 1. Compared to existing technologies, this invention features a left and right sliding cover plate symmetrically arranged on the cover plate body, with grooves on the cover plate body for guiding and limiting movement. This allows the sliding cover plate to reciprocate relative to the display screen's image area, thereby covering or revealing the display screen. The sliding cover plate structure incorporates latches and locking teeth on the cover plate body, ensuring reliable locking when closed and preventing displacement due to vibration or accidental contact. Furthermore, a rubber anti-collision sealing strip is provided on the side closest to the display screen's image area, which not only provides cushioning but also enhances the sealing performance when the cover plate is closed. Compared to traditional fixed cover plates, this structure offers dynamic protection and the ability to switch between usage scenarios, significantly improving the protection performance of the display module and the convenience of user operation.

[0019] 2. The cover structure of this invention includes a movable acrylic sliding cover and a fixed glass cover. The sliding cover is used to cover or open the display area and has advantages such as being lightweight, high-strength, and highly formable, making it suitable for mechanical sliding and fitting. The glass cover, as the basic support structure, has a multi-layer coating design on its front side, including a magnesium fluoride layer, a graphene layer, and a titanium nitride layer, which effectively improves the optical transmittance, hardness, and wear resistance of the cover surface. Through the division of labor and cooperation between the sliding and fixed components, the durability and optical performance of the components are ensured without increasing the frictional loss of the sliding mechanism, achieving an optimal combination of structural design and functional performance.

[0020] 3. In this invention, the glass cover adopts an advanced multi-layer film structure design, including a magnesium fluoride layer to reduce reflection and improve light transmittance, a graphene layer to enhance scratch resistance and provide electromagnetic shielding, and a titanium nitride layer to further improve hardness and wear resistance. In addition, a temperature-sensitive color-changing ink layer is provided on the back edge area of ​​the glass cover, giving the product a temperature-sensing display effect and enhancing its fun and interactivity. To ensure the durability of the temperature-sensitive ink layer, a chromium protective layer is provided underneath to effectively prevent scratches and wear. The screen-printed ink layer beneath the structure not only enhances concealment and aesthetics but also allows for customizable colors, giving the glass cover greater adaptability in terms of structural integration and visual consistency. This overall design gives the glass cover not only basic attributes such as protection and light transmittance but also integrates multiple added values ​​such as intelligent sensing and aesthetic unity, expanding the product's application scenarios.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 like Figure 1-5 As shown, this embodiment discloses a movable cover plate that can cover a display module, the structure of which includes: Cover plate body 1: It is the mounting base of the overall structure, and its shape matches the display module. It is used to accommodate and protect the display module. A rectangular opening is provided in the center of the cover plate body to form the display area 10 of the display screen. This area is used to show the display screen.

[0024] Sliding cover: including a left sliding cover 21 and a right sliding cover 22 arranged symmetrically. Preferably, the material is transparent or semi-transparent acrylic sheet, which has a certain impact resistance and processability.

[0025] When not in use, the two sliding covers can slide from both sides toward the center to close and cover the display screen display area 10; when it is necessary to view the display content, the two sliding covers slide to both sides to open, revealing the entire display screen display area 10.

[0026] Cover plate groove 32: It is set on both sides of the inner edge of the cover plate body 1, and plays a guiding and limiting role, so that the left sliding cover plate 21 and the right sliding cover plate 22 move along a fixed trajectory to avoid sliding deviation.

[0027] Sliding latch mechanism: Both the left sliding cover plate 21 and the right sliding cover plate 22 have a sliding base plate 201 at their bottom, on which a downward-facing latch 202 is provided. The cover plate body 1 has a matching latch tooth 31 inside, including an inclined surface 311 and a limiting surface 312. The front end of the latch 202 has a guide part 203, including a guide surface 204 and a latch tail section 205 that can be fixedly engaged with the limiting surface. When the left and right sliding covers are closed, the latch tail section 205 is embedded in the limiting surface 312, realizing the closing and locking of the sliding covers.

[0028] Preferably, to improve service life and engagement strength, the buckle 202 is preferably made of an elastic material, such as polycarbonate PC or thermoplastic elastomer TPE, which can ensure deformation fit and facilitate long-term repeated use.

[0029] Preferably, in order to improve the sealing and buffering performance in the closed state, rubber anti-collision sealing strips are provided on the side of the left sliding cover 21 and the right sliding cover 22 that are relatively close to the display screen display area 10. When the two sliding covers are closed, the sealing strips come into contact with each other, which can block dust and buffer impact.

[0030] Example 2 like Figure 6 As shown, in the above-described movable cover structure, more preferably, the present invention further includes a glass cover for enhancing protective performance, which is installed at the bottom of the cover body 1 or attached to the surface of the display module, and its structure is as follows: Glass substrate: High aluminosilicate glass or Corning Gorilla Glass is selected, with a thickness of 0.3mm to 0.5mm, which has good mechanical strength and light transmission performance.

[0031] The front coating layer structure is deposited sequentially from the outside to the inside: The magnesium fluoride layer 13, with a thickness of 5-10 nm, has a low refractive index and excellent light transmittance, reducing surface reflection and improving screen clarity. The graphene layer 12, with a thickness of 20-30 nm, is deposited by chemical vapor deposition (CVD) or spraying, providing high surface hardness and scratch resistance, while also possessing excellent thermal conductivity and electromagnetic shielding capabilities. The titanium nitride layer 11, with a thickness of 5-10 nm, provides high hardness and wear resistance, while also having a certain optical interference effect, enhancing surface decoration and corrosion resistance.

[0032] A thermochromic ink layer 14 is printed around the back edge of the glass cover plate 1. Preferably, the thickness is 8-10 μm. The ink layer can change color according to changes in the external temperature, so as to provide temperature indication and interactive visual effects. Below the temperature-sensitive ink layer 14 is a metal protective layer 15 chromium layer, preferably with a thickness of 5 to 8 μm, which is deposited by magnetron sputtering to effectively prevent the ink layer from being scratched or worn, and to ensure its long-term functional stability.

[0033] This functional coating structure employs a multi-layer synergistic approach, significantly improving the cover plate's wear resistance, scratch resistance, light transmittance, functionality, and aesthetics.
