Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a cover plate support structure for a far-viewing screen. Background Technology

[0002] In recent years, new home display products have emerged continuously, from small, portable tablets to smartly upgraded televisions, and new projector products, bringing users different audio-visual display experiences and customized choices for different scenarios. For example, tablets can be used for easy portability; televisions can be used for watching movies at home; and projectors can be chosen if a large screen display is required.

[0003] However, each of the aforementioned products has its shortcomings. For example, if a family needs a large-screen display but lacks sufficient projection space, then clearly none of the three types of products mentioned above can meet this need. Existing technology utilizes AR optics principles, allowing the projector to be placed simply on a table, achieving a large-screen projection effect in a small space through AR virtual optical projection technology. However, due to optical requirements, this technology necessitates a cover plate above the display for light blocking. Currently, these covers cannot be folded and stored, resulting in a large footprint and the cover plate being easily damaged due to insufficient strength, thus affecting the product's performance and lifespan.

[0004] Based on the above reasons, this utility model provides a cover plate support structure for a far-viewing screen. By utilizing the damping pivot and the interference fit and position setting of the latch and two grooves, the cover plate can be flexibly flipped, effectively opened and closed, and stably supported, thereby satisfying the storage, dustproof, and impact-proof effects of the light-shielding cover plate and the overall projector. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cover plate support structure for a far-viewing screen. By utilizing the damping pivot and the interference fit and position setting of the latch and two grooves, the cover plate can be flexibly flipped, effectively opened and closed, and stably supported, thereby satisfying the storage, dustproof, and impact-proof effects of the light-shielding cover plate and the overall projector.

[0006] To achieve the above objectives, this utility model provides a cover plate support structure for a far-viewing screen, including a middle frame and an upper cover plate. A bracket is provided on the upper side of the middle frame, and a bracket groove is provided on one side of the bracket. A latch is provided inside the bracket groove. A connecting seat is provided on the upper cover plate at a position corresponding to the bracket groove. The connecting seat is provided with a mounting hole, and a rotating part of a rotating shaft is installed in the mounting hole. The fixed part of the rotating shaft is installed in the bracket. The bottom of the connecting seat is provided with groove one and groove two, which cooperate with the latch to achieve a slotted engagement.

[0007] When the top cover is fully open, the latch engages with groove one; when the top cover is fully closed, the latch engages with groove two.

[0008] The height of the latch is equivalent to the depth of groove one and groove two.

[0009] The interference fit between the latch and groove 2 is greater than the interference fit between the latch and groove 1.

[0010] The cross-sectional area of ​​the fixed part of the shaft is larger than that of the rotating part.

[0011] The shaft is a damped shaft.

[0012] Compared with existing technologies, this utility model connects the upper cover plate to the bracket on the middle frame through a damping hinge, enabling the upper cover plate to flip flexibly. Simultaneously, the design of the groove and latch ensures that it is properly closed and opened. Overall, it achieves flexible opening and closing, provides stable support, and also offers dustproof and impact-resistant properties, thus enhancing the projector's performance.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] See Figures 1-6This utility model provides a cover plate support structure for a far-viewing screen, including a middle frame 1 and an upper cover plate 4. A bracket 7 is provided on the upper side of the middle frame 1, and a bracket groove 10 is provided on one side of the bracket 7. A latch 2 is provided inside the bracket groove 10. A connecting seat 9 is provided on the upper cover plate 4 at a position corresponding to the bracket groove 10. A mounting hole 8 is provided on the connecting seat 9. A rotating part 6-1 of a rotating shaft 6 is installed in the mounting hole 8. A fixing part 6-2 of the rotating shaft 6 is installed in the bracket 7. The bottom of the connecting seat 9 is provided with a groove 3 and a groove 5 that cooperate with the latch 2 to achieve a slotted engagement.

[0023] When the top cover 4 is fully open, the latch 2 and the groove 3 are properly engaged; when the top cover 4 is fully closed, the latch 2 and the groove 5 are properly engaged.

[0024] The height of the latch 2 is approximately equal to the depth of the groove 3 and the groove 5.

[0025] The interference fit between latch 2 and groove 2 is greater than the interference fit between latch 2 and groove 3.

[0026] The cross-sectional area of ​​the fixed part 6-2 of the rotating shaft 6 is larger than that of the rotating part 6-1.

[0027] Shaft 6 is a damped shaft.

[0028] Working principle:

[0029] See Figures 1-6 This invention requires minimal adjustment. When the upper cover 4 is fully closed, the latch 2 is fully engaged in the second groove 5, and the upper cover 4 is completely closed due to the interference fit. When it needs to be opened, the upper cover 4 is manually pried open. Since the upper cover 4 is connected to the bracket 7 on the middle frame 1 via the pivot 6, the upper cover 4 opens along the bracket 7 under the action of the rotating part 6-1 of the pivot 6. When fully open, the latch 2 is fully engaged in the first groove 3. Because the interference fit between the latch 2 and the first groove 3 is stronger at this time, it can support the weight of the upper cover 4 and maintain stability. Since the position of the latch 2 needs to meet the requirement of maintaining a complete engagement with the first groove 3 and the second groove 5 when fully closed and open, the position of the latch 2 is opposite to the positions of the first groove 3 and the second groove 5. If any one of the three positions is adjusted, the other two positions will also be adjusted accordingly, as long as the latch can be fully engaged when fully open or closed.

[0030] In addition, in order to meet the force and damping feel required to open or close the top cover 4, and to ensure that the top cover 4 can remain stable in any position, the torque of the damping shaft 6 must meet the following condition: Torque = Weight of the top cover x Width of the top cover.

[0031] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0032] This invention comprehensively solves the shortcomings of existing projector designs where the cover cannot be folded for storage, resulting in a large footprint and insufficient support. By utilizing a damping hinge to connect the upper cover to the bracket on the middle frame, the upper cover can be flexibly flipped. Simultaneously, the groove and latch design ensures proper opening and closing, providing overall flexibility, stability, dust protection, and impact resistance, thus enhancing the projector's performance.
