Description

Technical Field

[0001] This application relates to the field of projection screen technology, and in particular to a projection screen. Background Technology

[0002] A projector screen, also known as a framed projection screen, is traditionally installed by assembling the entire screen and hanging it on a flat wall. Because the frame itself has a certain thickness, the overall frame protrudes from the wall, affecting the wall's overall appearance and aesthetics. While pre-drilling a recessed groove in the wall to create a wall hole allows the screen to be embedded, the hole must be larger than the screen itself to ensure a proper fit. However, this results in gaps between the screen and the wall's sidewalls, still failing to address the issue of wall aesthetics. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] This application relates to a projection screen, which includes a screen 1000 and a frame assembly 2000, with the screen 1000 disposed on the frame assembly 2000. A baffle 2100 is disposed on the outer edge of the frame of the frame assembly 2000, and the baffle 2100 is located on the surface of the wall.

[0029] With the side of the projection screen from which the image is viewed as the front side, the baffle 2100 is used to cover the gap between the frame assembly 2000 and the wall opening, thereby improving the overall aesthetics of the projection screen installed in the wall opening. Furthermore, the installation position of the frame assembly 2000 in the wall opening can be adjusted horizontally. This ensures the accurate installation position of the projection screen and also allows for the uniformity of the left and right gaps between the outer side of the frame assembly 2000 and the wall opening, so that the baffle 2100 can cover the gaps on both sides.

[0030] The frame assembly 2000 is rectangular, and correspondingly, the curtain 1000 is rectangular. The frame assembly 2000 has four sequentially connected borders, which together form the frame assembly 2000. Along the length of the borders, a baffle 2100 is arranged to the same length as the borders. The area enclosed by the frame assembly 2000 is considered the inner side, and the area outside the frame assembly 2000 is considered the outer side. The baffle 2100 is located on the outer side of the borders. Along the width of the borders, the baffle 2100 protrudes from the outer edge of the borders to form a wing, thus enabling the baffle 2100 to cover the gap between the outer side of the border and the inner wall of the wall opening.

[0031] It should be noted that the baffle 2100 extends outward along the front surface parallel to the frame assembly 2000, and the baffle 2100 is flush with the front surface of the frame assembly 2000, further improving the surface flatness of the projection screen. Alternatively, the front surface of the baffle 2100 is inclined towards the surface of the wall to reduce the step height between the baffle 2100 and the wall, thereby improving the flatness of the projection screen and the wall.

[0032] In some embodiments, the frame assembly 2000 includes an inner frame 2200 and an outer frame 2300, both of which are set to a rectangular frame shape, with the inner frame 2200 located inside the outer frame 2300.

[0033] The screen 1000 is disposed on the front surface of the inner frame 2200, and the outer frame 2300 is connected to the inner frame 2200 and presses the screen 1000 against the front surface of the inner frame 2200. The outer frame 2300 can apply pressure to the four sides of the screen 1000 so that the four sides of the screen 1000 fit against the front surface of the four edges of the inner frame 2200.

[0034] It is understandable that the baffle 2100 is set on the outer frame 2300, and the baffle 2100 is located on the edge of the outer frame 2300.

[0035] In some examples, the baffle 2100 is located on the front side of the outer frame 2300. Further, in the width direction of the frame, a portion of the baffle 2100 extends outward to cover the gap between the frame assembly 2000 and the wall opening, while another portion extends inward to press the curtain 1000 against the front surface of the inner frame 2200. It is understood that this inwardly extending portion of the baffle 2100 not only presses the curtain 1000 but also serves to engage the outer frame 2300 and the inner frame 2200.

[0036] In some examples, the frames of the baffle 2100 and the outer frame 2300 are made of a single piece of profile. Furthermore, the frames of the baffle 2100 and the outer frame 2300 are made of a single piece of aluminum profile, which is lightweight, inexpensive, and has sufficient structural strength.

[0037] It should be noted that, in the width direction of the frame, the outer edge of the outer frame 2300 is engaged with the outer edge of the inner frame 2200 via an inwardly extending baffle 2100. A engaging structure 2301 is provided on the inner edge of the outer frame 2300, protruding from the front surface of the outer frame 2300. The engaging structure 2301 can engage with the inner edge of the inner frame 2200. It can be understood that the engaging structure 2301, in conjunction with the inwardly extending baffle 2100, achieves the engagement between the outer frame 2300 and the inner frame 2200.

[0038] In some embodiments, the frame assembly 2000 is provided with a snap-fit ​​member 3100, which is disposed on the edge of the outer frame 2300. A snap-fit ​​seat 3200 is disposed in the wall opening and configured to correspond to the snap-fit ​​member 3100. The snap-fit ​​seat 3200 is used to connect to the snap-fit ​​seat 3200 in the wall opening, and the snap-fit ​​seat 3200 provides support for the snap-fit ​​member 3100 so that the projection screen can be installed in the wall opening.

[0039] Furthermore, the snap-fit ​​3100 is disposed on the rear side of the frame of the outer frame 2300. Compared with the snap-fit ​​3100 being disposed on the outer side of the frame of the outer frame 2300, the snap-fit ​​3100 being located on the rear side of the frame can reduce the gap width between the frame assembly 2000 and the wall opening.

[0040] In some examples, the vertical borders of the outer frame 2300 are provided with at least one snap-fit ​​element 3100. When there are at least two snap-fit ​​elements 3100, they are spaced apart along the length of the border. It can be understood that both vertical borders of the outer frame 2300 are provided with snap-fit ​​elements 3100.

[0041] Regarding the distribution of the connector 3100, at least the following alternative embodiments exist.

[0042] In some alternative embodiments, the lateral borders of the outer frame 2300 are provided with at least one snap-fit ​​member 3100. Specifically, the upper lateral border of the outer frame 2300 is provided with a snap-fit ​​member 3100, or both the upper and lower lateral borders of the outer frame 2300 are provided with snap-fit ​​members 3100.

[0043] In some alternative embodiments, the two vertical edges and at least one horizontal edge of the outer frame 2300 are provided with snap-fit ​​elements 3100.

[0044] In some examples, the snap-fit ​​connector 3100 is provided with a snap-fit ​​slot 3101, which snaps into the snap-fit ​​base 3200. Specifically, the snap-fit ​​connector 3100 is provided with a snap-fit ​​end 3102, and the snap-fit ​​slot 3101 is located at the snap-fit ​​end 3102. The opening of the snap-fit ​​slot 3101 is arranged downward so that the snap-fit ​​slot 3101 can be disposed in the snap-fit ​​base 3200 from top to bottom.

[0045] Furthermore, the snap-fit ​​part 3100 is set as a sheet metal part, and the snap-fit ​​part 3100 is bent backward to form a snap-fit ​​end 3102.

[0046] In some examples, the mounting bracket 3200 is provided with a horizontal support structure 3201, and the slot 3101 of the mounting member 3100 is engaged with the horizontal support structure 3201 from top to bottom. Furthermore, the slot 3101 is laterally movable and engaged with the horizontal support structure 3201, allowing the mounting member 3100 to move laterally on the horizontal support structure 3201 to adjust the position of the projection screen left and right. This ensures that the gaps between the left and right sides of the frame assembly 2000 and the wall openings are uniform, and that the baffles 2100 on both sides of the frame assembly 2000 can cover the gaps.

[0047] In some examples, one end of the lateral support structure 3201 is connected to the latching seat 3200, and the other end is provided with a limiting protrusion 3202. The limiting protrusion 3202 is used to abut against the side of the latching end 3102 on the latching member 3100. In this case, the limiting protrusion 3202 can prevent the latching member 3100 from detaching from the lateral support structure 3201 due to lateral movement.

[0048] Specifically, the snap-fit ​​connector 3200 is a sheet metal part, and the snap-fit ​​connector 3200 is bent to form a transverse support structure 3201.

[0049] It should be noted that the arrangement of the connector 3100 and the connector 3200 can be alternatively designed as follows: the frame assembly 2000 has a connector 3200 on its edge, the connector 3200 is located on the outer frame 2300, and the connector 3200 is used to connect the connector 3100 in the wall hole and install the projection screen in the wall hole.

[0050] In this case, the vertical border of the outer frame 2300 is provided with at least one snap-fit ​​seat 3200. Alternatively, the horizontal border of the outer frame 2300 is provided with snap-fit ​​seat 3200; or, both the horizontal and vertical borders of the outer frame 2300 are provided with snap-fit ​​seat 3200.

[0051] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application 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 this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
