Description

Technical Field

[0001] This invention relates to the field of display module technology, specifically to a display module structure and its backplate. Background Technology

[0002] For example, Chinese patent CN105549246B discloses a display module structure and its back plate. The display module structure is used in a liquid crystal display or liquid crystal television. The back plate has a bent plate around its inner side and a fastening piece on the bent plate. The front frame is fitted around the back plate and is fastened to the fastening piece. The middle frame covers the front frame and the back plate, and is fitted around the bent plate and abuts against the fastening piece and the inner side of the front frame respectively.

[0003] However, the above solutions have the following shortcomings: In order to ensure the sealing between components and prevent dust or water from entering the module, existing display modules often apply some sealant at the connection between components to prevent water or dust from entering the module. However, when it is necessary to repair or replace the components in the module, the operator still needs to remove the residual sealant after removing the components, so that there are no gaps between the components after the repair is completed and the sealant is applied. This method is relatively cumbersome. Therefore, we have introduced a display module structure and its backplate. Summary of the Invention

[0004] The purpose of this invention is to provide a display module structure and its backplate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A display module backplate includes a front frame, a middle frame, and a rear panel. A transparent glass plate is fixedly installed inside the front frame. The middle frame is located inside the rear panel, and the rear panel is located inside the front frame. Locking mechanisms are provided around one side of the front frame and are connected to the rear panel. An annular groove is formed inside the front frame, and a liquid storage mechanism is attached inside the annular groove to store sealing liquid. Several T-shaped push rods are provided inside the annular groove.

[0007] The T-shaped push rod is movably connected to the inner side of the front frame. The end of the T-shaped push rod away from the liquid storage mechanism is in contact with the locking mechanism. A sealing groove is provided on the outer side of the rear plate. A tension strip is pasted around the sealing groove. A pull rod is fixedly connected to the upper end of the tension strip.

[0008] Preferably, the locking mechanism includes a movable plate, which is movably connected to a connecting groove located on one side of the front frame. A pressing rod and a plastic locking rod are fixedly connected to the movable plate near the rear plate. The plastic locking rod is engaged in a locking groove located in the rear plate.

[0009] Preferably, the liquid storage mechanism includes an annular storage bag with a plurality of drain ports on the inner side of the annular storage bag. A baffle is attached to the drain port. When the T-shaped push rod squeezes the annular storage bag, the sealing liquid pushes open the baffle and is discharged from the drain port.

[0010] Preferably, a first limiting rod is fixedly connected to all four sides of the inner side of the front frame, the first limiting rod is engaged in a first limiting groove, the first limiting groove is opened on the outer side of the rear plate, and a second limiting rod is fixedly connected to all four sides of the inner side of the rear plate, the second limiting rod is engaged in a second limiting groove, the second limiting groove is opened on the outer side of the middle frame.

[0011] Preferably, the end of the extrusion rod near the T-shaped push rod is arc-shaped, and the end of the T-shaped push rod near the extrusion rod is inclined.

[0012] In addition, to achieve the above objectives, the present invention also provides a display module structure, including the display module backplate described above.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through the setting of the liquid storage mechanism and the pull belt, allows the T-shaped push rod to squeeze the liquid storage mechanism when the locking mechanism locks the front frame and the rear plate together, so that the sealing liquid enters the sealing groove and seals the gap between the front frame and the rear plate. When maintenance is required, the locking mechanism is released, the front frame and the rear plate are separated, and the pull rod is pulled upward to drive the pull belt to move. The moving pull belt pulls the solidified sealant out of the sealing groove, making the operation convenient. Attached Figure Description

[0021] 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, and 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.

[0022] Please see Figure 1-6 The present invention provides a technical solution: Example 1:

[0023] A display module backplate includes a front frame 1, a middle frame 2, and a rear plate 3. The inner side of the middle frame 2 is used to install the display screen. The middle frame 2 is located inside the rear plate 3. A transparent glass plate 21 is fixedly installed inside the front frame 1. The rear plate 3 is located inside the front frame 1. Locking mechanisms are provided around one side of the front frame 1. The locking mechanisms are connected to the rear plate 3. After the front frame 1 is snapped onto the outside of the rear plate 3, the locking mechanisms are pushed down to connect the locking mechanisms with the rear plate 3. The locking mechanisms limit and fix the front frame 1 and the rear plate 3 together. An annular groove 11 is provided on the inner side of the front frame 1. A liquid storage mechanism is attached in the annular groove 11 to store sealing liquid. Several T-shaped push rods 12 are provided in the annular groove 11. When the locking mechanism moves, the T-shaped push rods 12 are squeezed and pushed. The movement of the T-shaped push rods 12 squeezes the liquid storage mechanism, allowing the sealing liquid in the liquid storage mechanism to enter the sealing groove 10.

[0024] T-shaped push rod 12 is movably connected to the inside of the front frame 1. The end of T-shaped push rod 12 away from the liquid storage mechanism is in contact with the locking mechanism. A sealing groove 10 is provided on the outside of the rear plate 3. A pull strip 9 is wrapped around the sealing groove 10. A pull rod 19 is fixedly connected to the upper end of the pull strip 9. The front frame 1 is removed from the outside of the rear plate 3. The pull strip 9 is moved by pulling the pull rod 19 upward. The movement of the pull strip 9 pulls out the sealing groove 10. After the pull strip 9 is pulled out, a new pull strip 9 is wrapped and pasted into the sealing groove 10, and the new liquid storage mechanism is pasted into the annular groove 11. Example 2:

[0025] Based on Example 1, in order to facilitate the cleaning of the solidified sealant by the operator, the locking mechanism includes a movable plate 4, which is movably connected to the connecting groove 14. The connecting groove 14 is opened in one side of the front frame 1. The movable plate 4 is fixedly connected to the side near the rear plate 3 with a pressing rod 13 and a plastic locking rod 15. The plastic locking rod 15 is engaged in the locking groove 16, which is opened in the rear plate 3. Pressing the movable plate 4 downwards causes the plastic locking rod 15 to engage in the locking groove 16. By engaging the plastic locking rod 15 in the locking groove 16, the front frame 1 and the rear plate 3 are fixed together. At the same time, during the movement of the movable plate 4, the pressing rod 13 will rotate. During the rotation, the pressing rod 13 will press the T-shaped push rod 12.

[0026] The liquid storage mechanism includes an annular storage bag 20, with several drain ports 18 on the inner side of the annular storage bag 20. A baffle 17 is attached to the drain port 18. When the T-shaped push rod 12 squeezes the annular storage bag 20, the sealing liquid pushes open the baffle 17 and is discharged from the drain port 18. The T-shaped push rod 12 moves to squeeze the annular storage bag 20. After the annular storage bag 20 is squeezed, the sealing liquid inside it enters the drain port 18. The baffle 17 located in the drain port 18 is pushed out. At this time, the sealing liquid enters the sealing groove 10 to seal the connection between the rear plate 3 and the front frame 1.

[0027] A first limiting rod 8 is fixedly connected to all four sides of the inner side of the front frame 1. The first limiting rod 8 is engaged in the first limiting groove 7. The first limiting groove 7 is opened on the outer side of the rear plate 3. A second limiting rod 6 is fixedly connected to all four sides of the inner side of the rear plate 3. The second limiting rod 6 is engaged in the second limiting groove 5. The second limiting groove 5 is opened on the outer side of the middle frame 2.

[0028] The end of the extrusion rod 13 near the T-shaped push rod 12 is arc-shaped, and the end of the T-shaped push rod 12 near the extrusion rod 13 is inclined.

[0029] In addition, to achieve the above objectives, the present invention also provides a display module structure, including the aforementioned display module backplate.

[0030] Working principle: When in use, press the middle frame 2 to the inside of the back plate 3. Under the pressure of the middle frame 2, the second limiting rod 6 will be engaged in the second limiting groove 5. At this time, the middle frame 2 and the back plate 3 are connected together. Install the display screen to the inside of the middle frame 2. Wrap the pull strap 9 around and stick it to the bottom of the sealing groove 10. Stick the annular sealing bag 20 containing sealing liquid into the annular groove 11. After sticking, put the front frame 1 on the outside of the back plate 3. At this time, the first limiting rod 8 will be engaged in the first limiting groove 7. The front frame 1 will be connected to the back plate 3. At the same time, the annular groove 11 and the sealing groove 10 are aligned. Press down the movable plate 4 so that the plastic locking rod 15 is engaged in the locking groove 16. By engaging the plastic locking rod 15 in the locking groove 16, the front frame 1 and the back plate 3 are fixed together.

[0031] Meanwhile, as the movable plate 4 moves, it will drive the squeezing rod 13 to rotate. During the rotation, the squeezing rod 13 will squeeze the T-shaped push rod 12. At this time, the T-shaped push rod 12 moves to squeeze the annular storage bag 20. After the annular storage bag 20 is squeezed, the sealing liquid inside it enters the drain port 18. The baffle 17 located in the drain port 18 will be pushed out. At this time, the sealing liquid will enter the sealing groove 10 to seal the connection between the rear plate 3 and the front frame 1.

[0032] When parts need to be repaired, push the movable plate 4 upward to disengage the plastic locking rod 15 from the locking groove 16, remove the front frame 1 from the outside of the rear plate 3, and move the pull strip 9 by pulling the pull rod 19 upward. The movement of the pull strip 9 will pull out the solidified sealant set in the sealing groove 10. After the pull strip 9 has been pulled out, rewrap and stick the new pull strip 9 in the sealing groove 10, and stick the new annular storage bag 20 in the annular groove 11.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
