Description

Technical Field

[0001] The present application relates to the field of projection display, and in particular to a frame screen. Background Art

[0002] Existing frame screens consist of a supporting structure, a membrane, and a frame, with a retaining strip installed within the frame. During installation, the membrane and retaining strip must be connected first, then pushed into the frame to secure. This installation process can easily cause scratches on the membrane, leading to production quality issues.

[0003] In order to solve this technical problem, this application provides a new technical solution. Utility Model Content

[0004] The present application provides a frame screen to solve the production quality problem of scratches easily caused during the installation process, which leads to scratches on the diaphragm.

[0005] The technical solutions provided in this application are as follows:

[0006] A frame screen includes a support structure, a diaphragm and a frame. The support structure is adhered to the non-imaging display surface of the diaphragm, and the frame is arranged on the four edges of the diaphragm. The frame includes a first frame and a second frame arranged opposite to each other. The first frame includes a first component and a second component. The first component is used to lock the diaphragm, and the second component is used to stretch the diaphragm. The first component includes a hinge embedded in the second component, a limiting portion for locking the diaphragm, and a pressing portion for facilitating the control of the movement of the first component. The opening and closing of the first component and the second component are achieved by the hinge.

[0007] To avoid the situation in the prior art where the diaphragm needs to be pushed into the frame to be fixed during installation, which causes scratches, the technical solution of this application realizes the opening and closing of the first and second components through the split design of the first component and the second component. With this arrangement, during installation, the first and second components are opened, the diaphragm is fixed, and the first component is buckled down to complete the installation of the frame curtain, which not only simplifies the installation process but also ensures the production quality of the frame curtain.

[0008] The frame is arranged on the edges of the membrane to serve as a decorative frame curtain. The color of the frame can be changed according to actual needs, so as to meet the diversified personalized needs of customers.

[0009] In the present application, the first component is an integrally formed structure.

[0010] The structure of the frame curtain is simplified by providing the integrated molding structure of the first component.

[0011] In the present application, the second component includes a locking portion and a locking portion that cooperate with the first component; the locking portion is provided with an accommodating cavity for accommodating the hinge.

[0012] The second component's locking and latching parts are designed to achieve synergy with the first component. A cavity is provided in the locking part, and the hinge of the first component is placed therein. In this way, the hinge is always embedded in the second component, and the first component relies on the hinge to open and close with the second component.

[0013] In the present application, the clamping portion is L-shaped and is used to accommodate a clamping strip, which connects two opposite edges of the diaphragm.

[0014] The clip is connected to two opposite long edges of the membrane and is disposed within the retaining portion of the second component. When the edge of the membrane is pressed, the first frame cooperates with the clip to position and secure the membrane. In this way, the edge of the membrane is wrapped within the frame, which provides a certain aesthetic appeal.

[0015] In the present application, the clip strip is a rectangular parallelepiped structure. With this arrangement, the clip strip has a simple structure and is easy to manufacture, thereby simplifying the manufacturing difficulty of the frame curtain.

[0016] In the present application, the length of the clip is less than the length of the first frame. In this way, the clip is completely set inside the first frame and is not exposed outside the first frame, thereby ensuring the aesthetics of the entire frame screen.

[0017] In this application, the first and second frames are interlocked at their junctions. This enhances the strength of the frame screen's corners, ensuring overall stability. Furthermore, the frame screen's corners do not expose any structure to the outside, ensuring the aesthetics of the entire frame screen.

[0018] In the present application, the first frame and the second frame are connected by an L-shaped connector. By using the L-shaped connector, the strength of the edges of the first frame and the second frame is strengthened, thereby enhancing the stability of the entire frame screen.

[0019] In the present application, the frame curtain further comprises a base film, which is arranged on the side of the support structure away from the diaphragm. In this way, the base film not only protects the support structure but also facilitates the processing and shaping of the support structure.

[0020] In the present application, the frame curtain further includes a central vertical rod, which is arranged on a side of the support structure away from the membrane. The central vertical rod is parallel to the second frame, and the two opposite first frames are connected by the central vertical rod.

[0021] The provision of the middle vertical rod strengthens the strength of the frame formed by the first frame and the second frame, enhances the stability of the frame, and further improves the stability of the frame curtain. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0028] Figure 1 This is a schematic structural diagram of the first frame of the embodiment of the present application when it is locked; Figure 2 This is a structural diagram of the first frame in an open state of an embodiment of the present application; Figure 3 This is a partial diagram of the frame screen structure of an embodiment of the present application.

[0029] See also Figures 1 to 3 The frame curtain includes a support structure 300, a diaphragm 400 and a frame. The support structure 300 is pasted on the four edges of the diaphragm 400. The frame includes a first frame and a second frame that are oppositely arranged. The first frame includes a first component 100 and a second component 200. The first component 100 is used to lock the diaphragm 400, and the second component 200 is used to stretch the diaphragm 400. The first component 100 includes a hinge 110 embedded in the second component 200, a limiting portion 120 for locking the diaphragm 400, and a pressing portion 130 for facilitating the control of the movement of the first component 100.

[0030] During installation, the first component 100 is opened, the membrane 400 with the support structure 300 attached thereto is installed, and then the first component 100 is closed. This process is achieved by the hinge 110 to open and close the first component 100 and the second component 200.

[0031] The formation process of the entire frame curtain can be as follows:

[0032] First, adhere the support structure 300 to the non-imaging display surface of the film 400. The support structure 300 provides a certain amount of support for the flatness of the film 400. Open the first component 100 of the first frame and place the film 400 on top of the second component 200. Install the second frame. Then, buckle the first component 100 to complete the installation of the frame screen.

[0033] During the entire installation process, the diaphragm 400 does not need to be pushed from the outside of the frame to the inside to secure it, thus preventing scratches on the diaphragm 400 during the pushing process and ensuring the production quality of the frame screen. The split design of the first component 100 and the second component 200 allows for installation by simply opening the first component 100 and the second component 200, securing the diaphragm 400, and then snapping off the first component 100 to complete the installation of the frame screen. This simplifies the production process, makes installation more convenient, and effectively improves the production efficiency of the frame screen.

[0034] The frame is placed around the edges of the membrane 400 to prevent the edges of the membrane 400 and the support structure 300 from being exposed to the outside, thus solving the problem of the membrane 400 and the support structure 300 being easily scratched and protecting the entire frame screen. The frame is also placed around the edges of the membrane 400 to decorate the frame screen, making it more beautiful.

[0035] During the production process, the color of the border can also be changed according to actual needs to meet the diverse needs of customers and achieve personalized customization.

[0036] In the embodiment of the present application, the support structure 300 supports the diaphragm 400, flattens the diaphragm 400, and ensures the flatness of the frame screen. The diaphragm 400 has an imaging display function, with the side closest to the support structure 300 serving as a non-imaging display surface, and the side away from the support structure 300 serving as an imaging display surface. The first and second frames are combined to form a frame, enhancing the flatness of the frame screen and ensuring the imaging display effect of the frame screen. This simplifies the design of the frame screen, making its overall structure simpler, installation more convenient, and costs correspondingly reduced.

[0037] In this embodiment of the present application, in a cross section parallel to the second frame, support structure 300 is formed by a plurality of continuously connected arc-shaped structures. The arc-shaped tops of the arc-shaped structures are spaced apart to form a support surface, which supports the non-imaging display surface of film 400. Overall, support structure 300 can be considered as a single structure formed by a plurality of arc-shaped structures extending along the length of the first frame.

[0038] In this embodiment of the present application, a first frame is located along two opposing long edges of the film 400, enclosing the two long edges of the film 400; a second frame is located along two opposing short edges of the film 400, enclosing the two short edges of the film 400; the first and second frames are combined to form a frame. This arrangement serves as a decorative element for the entire frame screen. Furthermore, the color of the first and / or second frames can be changed as needed, allowing the frame screen to meet more personalized needs.

[0039] In the embodiment of the present application, the support structure 300 is formed by a plurality of continuously connected arc-shaped structures. The designs of the plurality of arc-shaped structures can be identical, that is, the shapes, dimensions, and external appearances of the arc-shaped structures are consistent, which facilitates the processing and molding of the support structure 300 and reduces production costs. The arc-shaped tops of the arc-shaped structures are spaced apart to form a bearing surface, which supports the non-imaging display surface of the diaphragm 400. That is, the bearing surface is formed by the arc-shaped tops of the arc-shaped structures as a support portion. When the support structure 300 is used to support the diaphragm 400, the arc-shaped tops of the arc-shaped structures ensure that the force acting in the extension direction of the arc-shaped tops is stable, thereby preventing deformation of the diaphragm 400, such as curling or bending, in this direction when supporting the diaphragm 400.

[0040] In the embodiment of the present application, when the several arc-shaped structures are completely consistent, of course, the arc-shaped tops of the support structure 300 are also completely consistent. This is conducive to the uniformity of the supporting force of the support structure 300 and maintains the flatness of the diaphragm 400 when it is unfolded, avoiding local bending, wavy lines, etc. on the frame curtain.

[0041] In the embodiment of the present application, the support structure 300 is formed by a plurality of continuously connected arc-shaped structures, indicating that the support structure 300 is a whole, rather than independent components. This ensures the continuity of the support structure 300 and prevents the support structure 300 from separating from the diaphragm 400 due to shaking or twisting of the local arc-shaped structures. This maintains a long-term and stable connection between the diaphragm 400 and the support structure 300, and the smoothness of the connection between the support structure 300 and the diaphragm 400.

[0042] In the embodiment of the present application, support structure 300 can be formed by bending a plastic or inorganic fiber-reinforced sheet material into a continuous arrangement through positive and negative arc bending. Specifically, support structure 300 is fabricated from a single piece of sheet material. This simplifies the manufacturing process while ensuring flatness and stability, resulting in a high degree of lightweighting and weight reduction. Forming the structure through sheet bending requires less structural strength from the sheet material itself. The positive and negative arc bending process strengthens the originally weak sheet material into a certain degree of bending resistance. This meets the requirements of support structure 300, resulting in a simple structure, ease of fabrication, and relatively low cost, thereby reducing the cost of the entire frame screen.

[0043] In the embodiment of the present application, the support structure 300 may also be formed by connecting and linking a plurality of types of arc-shaped structures. The specific configuration method may refer to the method of connecting and linking a plurality of arc-shaped structures.

[0044] In the embodiment of the present application, the diaphragm 400 can be an ordinary screen such as a white plastic screen, a metal screen, a bead screen, or an optical screen such as a Fresnel optical screen, a line grating screen, or a photon screen. Whether it is an ordinary screen or an optical screen, it can be used to image the image light. In other words, the diaphragm 400 can also be a single functional structural layer, or multiple functional structural layers. Of course, it must include an imaging display surface, which is indispensable for the imaging of the frame projection screen. The arc-shaped top of the arc-shaped structure of the support structure 300 is spaced to form a bearing surface, so that the imaging display surface is supported; in the longitudinal extension direction of the support structure 300, the imaging display surface also obtains a corresponding flattening force, which can avoid deformation problems such as curling and bending of the imaging display surface, ensure the flatness of the imaging display surface, and thus ensure the imaging effect.

[0045] In an embodiment of the present application, the size of the support structure 300 can be set to cover a range greater than or equal to 80% of the area of ​​the display area on the diaphragm 400. The support structure 300 is usually centered on the diaphragm 400. When the size of the support structure 300 covers 80% or more of the display area, the curling deformation of the side of the diaphragm 400 can be effectively eliminated.

[0046] In the embodiment of the present application, it is preferred that the size of the support structure 300 covers an area greater than or equal to 100% of the display area on the diaphragm 400. This configuration not only better resists deformation of the diaphragm 400, but also facilitates the connection and alignment of the support structure 300 and the diaphragm 400, thus facilitating manufacturing.

[0047] The first assembly 100 includes a hinge 110, a stopper 120, and a pressing portion 130. The hinge 110, movably connected to the second assembly 200, is the key to enabling the opening and closing of the first assembly 100. The stopper 120 is used to lock the diaphragm 400, and the pressing portion 130 controls the movement of the entire first assembly 100. These three components work together to facilitate the opening and closing of the first assembly 100. Furthermore, these three components can be integrally molded, simplifying the overall structure of the frame screen.

[0048] The second assembly 200 includes a locking portion 210 and a latching portion 220, which work in conjunction with the first assembly 100 to control the opening and closing of the two assemblies, simplifying the installation process of the frame screen. The locking portion 210 is provided with a receiving cavity, which accommodates the hinge 110. This ensures that the hinge 110 is always embedded in the second assembly 200. The first assembly 100 relies on the hinge 110 to achieve effective opening and closing with the second assembly 200.

[0049] The retaining portion 220 can be an L-shaped structure to accommodate the retaining strips, which are arranged oppositely to connect the two opposite long edges of the diaphragm 400. Thus, the retaining strips connecting the two opposite long edges of the diaphragm 400 are disposed within the retaining portion 220 of the second component 200. When the edges of the diaphragm 400 are pressed, the first frame cooperates with the retaining strips to secure the diaphragm 400 in place. This arrangement prevents the edges of the diaphragm 400 from protruding from the first frame, effectively keeping them contained within the first frame, thus ensuring the stability and aesthetics of the frame screen.

[0050] In the embodiment of the present application, the clip strip can be configured as a rectangular parallelepiped structure. This simplifies the clip strip structure and facilitates fabrication, thereby simplifying the production of the frame screen. To prevent the clip strip from being exposed outside the first frame, the clip strip is always shorter than the first frame. This ensures that the clip strip is completely embedded within the first frame, maintaining the aesthetics of the frame screen.

[0051] In addition, the card strips can be set as a hollow structure, so that the weight of the card strips can be reduced, and the weight of the entire frame curtain can be reduced.

[0052] In the embodiment of the present application, the first and second frames are interlocked at their junctions. This arrangement enhances the strength of the frame screen's corners, ensuring the overall stability of the frame screen. Furthermore, the frame screen's corners do not expose any structure to the outside, ensuring the aesthetics of the entire frame screen.

[0053] In the embodiment of the present application, the first frame and the second frame can be connected by an L-shaped connector. In this way, the strength of the edges of the first frame and the second frame is strengthened by the use of the L-shaped connector, thereby enhancing the stability of the entire frame screen.

[0054] In the embodiment of the present application, the edges of both ends of the L-shaped connector can be directly configured as arcs. This prevents sharp corners from scratching the frame screen during installation. This not only protects the safety of the installer, but also prevents sharp corners from scratching the first and second frames, thereby enhancing the safety of the frame screen during installation.

[0055] In the embodiment of the present application, the inner corner of the L-shaped connector can also be set to an arc shape. By setting the arc chamfer at the inner corner of the L-shaped connector, air is avoided and the installation connection is ensured to be in place.

[0056] In the embodiment of the present application, the outer corners of the L-shaped connector can also be set to be arc-shaped or inclined, so as to avoid the appearance of sharp corners and increase the safety factor of the entire installation process.

[0057] Of course, the corners of the L-shaped connector can also be set to right angles, which makes it easier to process the connector.

[0058] In this embodiment of the present application, the frame screen may further include a base film 500, which is disposed on the side of the support structure 300 away from the membrane 400. This protects the support structure 300 and facilitates the processing and forming of the support structure 300. The base film may be a plastic film, and may be bonded to the support structure 300.

[0059] In the embodiment of the present application, the frame screen may further include a central vertical rod, which is disposed on the side of the support structure 300 away from the membrane 400. The central vertical rod is parallel to the second frame, and the two opposing first frames are connected by the central vertical rod. The provision of the central vertical rod strengthens the frame formed by the first and second frames, enhances the stability of the entire frame, and thus improves the stability of the frame screen.
