Description

Technical Field

[0001] This invention relates to the field of display screen assembly technology, and more specifically to display screen assembly structures and display screen assembly systems. Background Technology

[0002] Currently, to improve sealing, displays are usually glued to the front frame of electronic devices for assembly.

[0003] The drawback of this structure is that the contact area between the display screen and the frame is limited, the part not connected to the frame lacks effective support, and this part occupies a large area. When the display screen is large in size and heavy in weight, relying solely on adhesive fixation can easily cause the display screen to deform, warp, or even fall off the frame. Summary of the Invention

[0004] In view of this, the present invention provides a display screen assembly structure and display screen assembly system to solve the problem that the display screen is prone to deformation, warping or even falling off the frame.

[0005] In a first aspect, the present invention provides a display screen assembly structure, comprising: a bracket having a mounting hole; a face frame having a recessed side forming a mounting cavity, the mounting cavity being adapted to mount the display screen and the bracket, the bracket being adapted to be mounted between the face frame and the display screen; the outer surface of the face frame having the mounting cavity being adapted to have a first gap with the outer surface of the display screen; a connector adapted to pass through the bracket and be fixedly connected to the display screen; a fixing member passing sequentially through the connector and the face frame and disposed on the mounting hole; the fixing member being located on the side of the face frame away from the display screen; a second gap being left between the outer surface of the face frame away from the display screen and the inner surface of the connector being close to the display screen; the second gap being smaller than the first gap.

[0006] Beneficial Effects: The display assembly structure of this invention uses a frame and a bracket to fix the two sides of the display screen respectively. If one side of the display screen detaches under force, it can be fixedly connected to the frame or bracket by the other side, thereby effectively reducing the risk of the display screen falling off. By setting a first gap and a second gap, space is provided for the display screen to move, reducing the risk of deformation, warping, and breakage of the display screen under external forces, as well as deformation of the frame under force. In addition, the second gap is smaller than the first gap, ensuring that the bracket continues to fix the display screen after it detaches from the frame, thereby effectively preventing the display screen from falling off the electronic device and improving the safety of the display screen.

[0007] In one alternative embodiment, the connector is located at the corner of the bracket and includes a hook portion and a connecting portion connected at an angle. The hook portion extends toward the inside of the bracket and is connected to the face frame. The hook portion has a first through hole for the fastener to pass through, and the connecting portion is adapted to pass through the bracket and be fixedly connected to the display screen.

[0008] Beneficial effects: The connector is located at the corner of the bracket, which does not obstruct the connection between the bracket and the display screen, making it convenient to use. The connector has a hook part and a connecting part, which, together with the fixing part, can connect the bracket, display screen and face frame at the same time, improving the installation stability of the display screen on the face frame and preventing the display screen from falling off.

[0009] In one optional embodiment, the bracket has a first positioning hole on its side, and the side of the connecting part extends along the length of the bracket to form a positioning post. The positioning post passes through the first positioning hole and is adapted to be fixedly connected to a second positioning hole on the side of the display screen.

[0010] Beneficial effects: The first positioning hole is located on the side of the connector. The positioning post passes through the first positioning hole and is suitable for fixed connection with the second positioning hole on the side of the display screen, which can effectively fix the bracket and the display screen.

[0011] In one alternative embodiment, the bracket is further provided with a press-fit stud, which has a threaded hole along its axial direction, forming a mounting hole.

[0012] Beneficial effects: The bracket uses the threaded holes of the press-fit studs to form the mounting holes, which is simple in structure and easy to use.

[0013] In one optional embodiment, the faceplate includes a mounting portion that extends horizontally toward the inner side of the faceplate and has a mounting groove and a second through hole; a hook portion fits against the surface of the mounting portion, a connecting portion is disposed in the mounting groove, and a fastener is adapted to pass through the first through hole and the second through hole in sequence and then be fixedly connected to the threaded hole.

[0014] Beneficial effects: The fastener passes through the first and second through holes and is fixedly connected to the threaded hole, thus securing the bracket, display screen, and front frame, facilitating installation. The front frame's mounting part and hook part are designed to fit together, increasing the contact area between the front frame and the connector, thereby improving the connection stability between the front frame and the connector.

[0015] In one alternative implementation, the diameter of the second through hole is larger than the outer diameter of the press-fit stud.

[0016] Beneficial effects: The diameter of the second through hole is larger than the outer diameter of the press-fit stud, which can give the display screen a certain amount of movement. When the display screen is subjected to external force, it can move along the second through hole to reduce the external force and effectively reduce the risk of frame deformation and display screen breakage.

[0017] In one alternative implementation, the fastener is a screw.

[0018] Beneficial effects: The fastener is a screw, which is low in cost, easy to use, and has strong fastening power.

[0019] In one optional embodiment, the bracket has multiple mounting holes at its four corners; multiple fasteners and connectors are provided accordingly, and the multiple fasteners are respectively adapted to pass through the connectors and the face frame in sequence and then be located in the mounting holes.

[0020] Beneficial effects: Multiple mounting holes are provided at the four corners of the bracket, and multiple fasteners are used to fix the bracket and the display screen, which can significantly improve the connection stability between the bracket and the display screen.

[0021] Secondly, the present invention also provides a display screen assembly system, comprising: a display screen, including a cover plate and a display panel that are fixedly attached to each other; the aforementioned display screen assembly structure; the cover plate being fixedly connected to the face frame, and the display panel being fixedly connected to the bracket via a connector.

[0022] Beneficial effects: Because the display assembly system includes a display assembly structure, it has the same effect as the display assembly structure, namely, it can effectively reduce the risk of display deformation, warping, and detachment, providing space for display deformation and reducing the risk of display breakage due to external forces and frame deformation under stress. Even if the connection between the cover plate and the frame fails, the display will loosen along with the connectors and fasteners. However, because the second gap is smaller than the first gap, the display will remain within the mounting cavity to prevent it from falling off.

[0023] In one optional embodiment, the mounting chamber includes a first chamber and a second chamber that are connected to each other, the first chamber and the second chamber forming a stepped surface, a cover plate is fixed to the stepped surface by adhesive and disposed in the first chamber; the display panel is disposed in the second chamber.

[0024] Beneficial effects: The cover plate is fixed to the step surface with adhesive, which provides good sealing and can reduce the contamination of the internal circuitry of the display screen by external dust and moisture. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Existing methods of fixing displays to frames using adhesive are ineffective at securing heavy displays, easily leading to deformation, warping, or even detachment. The embodiments of this invention use a frame and a bracket to fix the two sides of the display respectively. If one side of the display detaches under stress, it can be fixed to the frame or bracket by the other side, effectively reducing the risk of display deformation, warping, and detachment.

[0037] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a display screen assembly structure is provided, mainly comprising: a bracket 1, a face frame 2, a connector 3, and a fastener 4. The bracket 1 has a mounting hole 101. One side of the face frame 2 is recessed to form a mounting chamber, which is suitable for mounting a display screen 5 and the bracket 1. The bracket 1 is suitable for mounting between the face frame 2 and the display screen 5. A first gap is provided between the outer surface of the face frame 2 with the mounting chamber and the outer surface of the display screen 5. The connector 3 is suitable for passing through the bracket 1 and being fixedly connected to the display screen 5. The fastener 4 passes sequentially through the connector 3 and the face frame 2 and is disposed on the mounting hole 101. The fastener 4 is located on the side of the face frame 2 away from the display screen 5. A second gap is provided between the outer surface of the face frame 2 away from the display screen 5 and the inner surface of the connector 3 near the display screen 5. The second gap is smaller than the first gap.

[0039] In the display assembly structure of this invention, a frame 2 and a bracket 1 are used to fix the two sides of the display screen 5 respectively. If one side of the display screen 5 detaches under force, it can be fixedly connected to the frame 2 or the bracket 1 through the other side, thereby effectively reducing the risk of the display screen 5 falling off. By setting a first gap and a second gap, space is provided for the display screen 5 to move, reducing the risk of the display screen 5 deforming, warping, and breaking under external force, as well as the risk of the frame 2 deforming under force. In addition, the second gap is smaller than the first gap, which ensures that after the display screen 5 detaches from the frame 2, the bracket 1 continues to fix the display screen 5, thereby effectively preventing the display screen 5 from falling off the electronic device and improving the safety of the display screen 5.

[0040] Specifically, the outer surface of the side of the face frame 2 where the mounting chamber is located is adapted to have a first gap between it and the outer surface of the cover plate 501 of the display screen 5, the first gap being as follows: Figure 7 As shown by line segment F in the diagram. The display screen 5 can be completely placed inside the mounting cavity and is lower than the height of the mounting cavity; that is, the frame 2 can support and accommodate the display screen 5. A second gap is left between the outer surface of the frame 2 away from the display screen 5 and the inner surface of the connector 3 near the display screen 5. The second gap is as follows: Figure 7 As shown by line segment G in the diagram. The shape of the frame 2 is adapted to the shape of the display screen 5, and is generally rectangular.

[0041] In one embodiment, such as Figure 2 and Figure 3 As shown, connector 3 is located at the corner of bracket 1, which does not obstruct the connection between bracket 1 and display screen 5, making it convenient to use. Figure 4 As shown, the connector 3 includes a hook portion 301 and a connecting portion 302 connected at an angle. The hook portion 301 extends toward the inside of the bracket 1 and is connected to the face frame 2. Specifically, the hook portion 301 extends toward the inside of the bracket 1 along the length direction of the bracket 1. The hook portion 301 has a first through hole 303 for the fastener 4 to pass through, and the connecting portion 302 is adapted to pass through the bracket 1 and be fixedly connected to the display screen 5.

[0042] Specifically, the connector 3 is an L-shaped plate, comprising two connected right-angled plates. The two right-angled plates respectively form a hook portion 301 and a connecting portion 302. The surface of the hook portion 301 is fitted and connected to the surface of the frame 2. The connector 3, with its hook portion 301 and connecting portion 302, in conjunction with the fixing member 4, can simultaneously connect the bracket 1, the display screen 5, and the frame 2, improving the installation stability of the display screen 5 on the frame 2 and preventing the display screen 5 from falling off.

[0043] In one embodiment, such as Figure 2 and Figure 4 As shown, a first positioning hole 102 is provided on one side of the bracket 1. A positioning post 304 extends along the length of the bracket 1 from the side of the connecting part 302. The positioning post 304 passes through the first positioning hole 102 and is adapted to be fixedly connected to a second positioning hole 503 on the side of the display screen 5. The positioning post 304 can be a positioning pin. The first positioning hole 102 is located on the side of the bracket 1, and the positioning post 304 passes through the first positioning hole 102 and is adapted to be fixedly connected to the second positioning hole 503 on the side of the display screen 5, which can effectively fix the bracket 1 and the display screen 5.

[0044] In one embodiment, the bracket 1 is further provided with a press-fit stud 103, which has a threaded hole along its axial direction, forming a mounting hole 101. The bracket 1 uses the threaded hole of the press-fit stud 103 to form the mounting hole 101, which is simple in structure and convenient to use.

[0045] In some other embodiments, threaded holes can be directly formed on the surface of the bracket 1 as mounting holes 101, thereby further simplifying the structure of the bracket 1.

[0046] It should be noted that the embodiments of the present invention do not limit the method of fixing the bracket 1 and the face frame 2. It can be a fastening method or a snap-fit ​​method. Compared to a snap-fit ​​method, a fastener-type fixing structure is more robust. To improve the tightness of the bracket 1 and the face frame 2, in one embodiment, the bracket 1 is fixedly connected to the face frame 2 by multiple fasteners 6. Before assembling the display screen 5, the bracket 1 and the face frame 2 need to be fixedly connected by multiple fasteners 6.

[0047] For example, such as Figure 1 and Figure 2As shown, the outer edge of the faceplate 2 is provided with multiple fixing parts, which extend towards the inner side of the faceplate 2, and the lower surface of the fixing parts fits against the bracket 1. Each fixing part has two first through holes, and the bracket 1 has a corresponding second through hole. The fastener 6 passes through the first through hole and is fixedly connected to the second through hole. The second through hole can be a threaded hole, and the fastener 6 can be a screw or bolt, which is simple in structure and low in cost. In addition, using screws or bolts for the fastener 6 makes installation convenient and facilitates subsequent replacement and maintenance.

[0048] In one embodiment, the face frame 2 further includes a mounting portion 201, which extends horizontally toward the inner side of the face frame 2 and has a mounting groove 202 and a second through hole 203. A hook portion 301 is fitted to the surface of the mounting portion 201, and a connecting portion 302 is disposed within the mounting groove 202. A fixing member 4 is adapted to pass sequentially through the first through hole 303 and the second through hole 203 before being fixedly connected to a threaded hole. The fixing member 4 passes through the first through hole 303 and the second through hole 203 and is fixedly connected to the threaded hole, thus fixing the bracket 1, the display screen 5, and the face frame 2, facilitating installation. The surface of the mounting portion 201 and the hook portion 301 fitted together on the face frame 2 increases the contact area between the face frame 2 and the connecting member 3, thereby improving the connection stability between the face frame 2 and the connecting member 3.

[0049] Since the fastener 4 is fixedly connected to the threaded hole by passing through the first through hole 303 and the second through hole 203, the bracket 1, the display screen 5 and the face frame 2 are fixed. At this time, the second gap is the distance between the outer surface of the mounting part 201 away from the display screen 5 and the inner surface of the hook part 301 close to the display screen 5.

[0050] In one embodiment, the diameter of the second through hole 203 is larger than the outer diameter of the press-fit stud 103. This allows the display screen 5 a certain amount of movement, enabling it to move around the perimeter of the second through hole 203 when subjected to external force, thus mitigating the impact and effectively reducing the risk of deformation of the frame 2 and breakage of the display screen 5. Specifically, the diameter of the second through hole 203 is as follows: Figure 6 As shown by line segment D in the figure, the outer diameter of the press-fit stud 103 is as follows: Figure 6 Line segment E is shown in the diagram.

[0051] It should be noted that the embodiments of the present invention do not limit the fastener 4. In one embodiment, the fastener 4 can be a screw, which is low in cost, easy to use, and has strong fastening power.

[0052] In one embodiment, the bracket 1 has multiple mounting holes 101 at its four corners. Multiple fasteners 4 and connectors 3 are correspondingly provided, with each fastener 4 adapted to pass sequentially through the connector 3 and the face frame 2 before being positioned in the mounting holes 101. By providing multiple mounting holes 101 at the four corners of the bracket 1 and using multiple fasteners 4 to fix the face frame 2, bracket 1, and display screen 5, the connection stability between the face frame 2, bracket 1, and display screen 5 can be significantly improved. Additionally, mounting portions 201 are also located at the four corners of the face frame 2, corresponding to the mounting holes 101.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, in one feasible embodiment, in order to balance cost and connection stability between bracket 1 and display screen 5, bracket 1 is provided with two mounting holes 101 at each of its four corners.

[0054] According to an embodiment of the present invention, another aspect provides a display screen assembly system, mainly comprising: a display screen 5 and a display screen assembly structure. The display screen 5 includes a cover plate 501 and a display panel 502 that are fixedly attached to each other. The cover plate 501 is fixedly connected to the frame 2, and the display panel 502 is fixedly connected to the bracket 1 via a connector 3.

[0055] Because the display assembly system provided in this embodiment of the invention includes a display assembly structure, it has the same effect as the display assembly structure. That is, it can effectively reduce the risk of deformation, warping, and detachment of the display screen 5, leaving room for deformation of the display screen 5, and reducing the risk of the display screen 5 breaking under external force and the frame 2 deforming under force. After the connection between the cover plate 501 and the frame 2 fails, the display screen 5 will loosen along with the connector 3 and the fixing member 4, but because the second gap is smaller than the first gap, the display screen 5 will still be located in the mounting cavity to prevent the display screen 5 from falling off.

[0056] Compared to existing methods that only fix the cover plate 501 of the display screen 5 to the frame 2, while leaving the display panel 502 unsupported, resulting in the stress on the display screen 5 concentrated between the cover plate 501 and the frame 2, which cannot effectively support the structure of a large-sized display screen 5, this invention fixes the cover plate 501 of the display screen 5 to the frame 2 and the display panel 502 of the display screen 5 to the bracket 1, simultaneously supporting both the cover plate 501 and the display panel 502. This significantly improves the assembly stability of the display screen 5 and prevents it from falling off. By setting a first gap and a second gap, a certain amount of movement space is provided for the cover plate 501 and the display panel 502, preventing the display screen 5 from colliding with the frame 2 under stress, thus effectively protecting both the display screen 5 and the frame 2.

[0057] Specifically, the cover plate 501 and the display panel 502 can be bonded together using optical adhesive to improve the connection stability between them and prevent them from falling off. The side of the display panel 502 also extends to form a protrusion, which is hook-shaped and fits and is fixed to the surface of the bracket 1. The display panel 502 is generally rectangular; therefore, the cover plate 501 and the bracket 1 are also correspondingly rectangular, and the frame 2 is a hollow rectangular frame.

[0058] It should be noted that the display assembly system of the present invention is suitable for use in scenarios where the display screen 5 is large, especially for assembling displays 5 of 18 inches and above. For example, an ultrasonic equipment display screen. The cover plate 501 of the ultrasonic equipment display screen can be a glass cover plate, and the display panel 502 can be an LCD display panel (liquid crystal display panel). Of course, the cover plate 501 and the display panel 502 can also be selected from other conventional existing structures as needed.

[0059] In one embodiment, the mounting chamber includes a first chamber and a second chamber that are connected to each other, forming a stepped surface. A cover plate 501 is fixed to the stepped surface by adhesive and is disposed within the first chamber. The display panel 502 is disposed within the second chamber. The cover plate 501 is fixed to the stepped surface by adhesive, providing good sealing and reducing the risk of external dust and moisture contaminating the internal circuitry of the display screen 5. Alternatively, the cover plate 501 can be fixed to the stepped surface by adhesive backing.

[0060] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
