Description

Technical Field

[0001] The utility model relates to the technical field of components of AR display devices, and particularly to a storage cover plate applied to a desktop AR display device. Background Art

[0002] In recent years, new products in the field of home displays have emerged continuously. From small portable tablet computers to televisions after intelligent transformation, to new projector products, they have brought users audio-visual display experiences in different sub-scenarios. Users can choose appropriate products according to their current scenarios. For example, for easy portability, a tablet computer can be used; for watching movies at home, a television can be used; for large-screen display, a projector can be selected. However, the above products all have deficiencies. For example, if a family needs a large-screen display but does not have enough projection space, then obviously the above three products cannot meet this requirement. And we use AR optical technology to realize a display product that can be placed on a desktop and can achieve large-screen projection in a very small space through AR virtual optical projection technology.

[0003] Due to optical requirements, a cover plate must be provided above the display for light shielding. For the structural design of this light-shielding cover plate, the existing light-shielding cover plates cannot be folded and stored. This has caused a very large space occupation of the overall product, and due to insufficient strength of the light-shielding cover plate, it is very easy to be damaged during normal use by users. Therefore, we propose a storage cover plate applied to a desktop AR display device. Summary of the Utility Model

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0026] Please refer to Figures 1-9, in the embodiment of the present utility model, a storage cover plate applied to a desktop AR display device includes a first sliding hinge 1, a second sliding hinge 2, and a cover plate 9; both the first sliding hinge 1 and the second sliding hinge 2 are fan-shaped structures, the cover plate 9 is flipped through a rotating shaft 7, both sides of the cover plate 9 are provided with the first sliding hinge 1, both sides of the cover plate 9 are provided with inclined surface structures 91, the first sliding hinge 1 is located at the inclined surface structure 91 of the cover plate 9, when the cover plate 9 is turned up, the inclined surface structure 91 just abuts against the screen panel, thus playing a limiting role; the first sliding hinge 1 and the cover plate 9 are fixed through self-tapping screws 4, the first sliding hinge 1 is rotationally connected to the second sliding hinge 2 through a rotating shaft 6, a sliding groove 5 is opened at one end of the first sliding hinge 1 away from the rotating shaft 6, and the second sliding hinge 2 is provided with a fixing button matching with the sliding groove 5. The hinge assembly 1 is fixed on the cover plate 9 by five screws. These five screws play a role in fixing the hinge assembly and will not cause problems of horizontal and lateral swing. Then if the second sliding hinge 2 swings horizontally left and right, it will cause friction or even jamming when the two hinge assemblies enter the slot 8 or open out of the slot 8, thus affecting the normal opening and closing function. To solve this problem, we fix the second sliding hinge 2 through two fixing points.

[0027] It further includes a panel slot 8 for accommodating the first sliding hinge 1 and the second sliding hinge 2, and the panel slot 8 is located at the housing of the display device.

[0028] The fixing button 3 includes a fixing button body 31, the fixing button body 31 is installed on the second sliding hinge 2 through a fastening screw 32, and a hinge sliding groove 34 is opened in the fixing button body 31.

[0029] The rotating shaft 6 includes a clamping member one 61 and a clamping member two 63, the clamping member one 61 and the clamping member two 63 are connected through an adjusting screw 62, and a hinge slot 64 is formed between the clamping member one 61 and the clamping member two 63, and the second sliding hinge 2 is fixed in this slot. Thus, the second sliding hinge 2 is clamped so that the second sliding hinge 2 will not produce horizontal and lateral offset; the two clamping members are connected through the adjusting screw 62 and the tightening degree is adjusted through this screw.

[0030] This application is composed of five large components, namely the first sliding hinge 1 and the second sliding hinge 2, and these two components form the left sliding member. The right sliding member is the same as the left sliding member and will not be elaborated here. The component 9 is the cover plate.

[0031] The first sliding hinge 1 is fixed on the cover plate 9 through five self-tapping screws 4; during the sliding process, the position of the first sliding hinge 1 relative to the cover plate 9 remains unchanged, and at the same time, due to the fixation of the screws 4, it will not swing horizontally left and right.

[0032] The second sliding hinge 2 is connected to the first sliding hinge 1 at two points. One is the rotating shaft 6, and the other is the fixing button 3. The fixing button 3 is fixed on the second sliding hinge 2 and slides by being stuck in the sliding groove 5 through the concave groove on the fixing button 3.

[0033] The first sliding hinge 1 and the second sliding hinge 2 rotate through the same rotating shaft 6. At the same time, the first sliding hinge 1 and the second sliding hinge 2 will rotate into the groove 8 of the screen panel to achieve the final folding and storage function.

[0034] The cover plate 9 is flipped through two left and right rotating shafts 7. Among them, the rotating shaft 7 has a torque of 1 Nm. This rotating shaft 7 has damping characteristics, making the flipping smoother. Among them, the second part 72 of the rotating shaft is embedded in the base, and the first part 71 of the rotating shaft is embedded in the cover plate 9, so that the cover plate can rotate around the shaft 7, thereby realizing the opening and closing of the cover plate.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
