Description

Technical Field

[0001] The present invention relates to the technical field of display modules, and in particular to a display module structure and a back panel thereof. Background Art

[0002] For example, the Chinese patent with announcement number CN105549246B discloses a display module structure and its back panel. The display module structure is used in a liquid crystal display or a liquid crystal television. A bending plate is provided around the inner side surface of the back panel, and a buckle piece is provided on the bending plate. The front frame is sleeved on the outer periphery of the back panel and is fastened to the buckle piece. The middle frame is covered between the front frame and the back panel, and the middle frame is sleeved on the outer periphery of the bending plate and respectively abuts against the buckle piece and the inner side surface of the front frame.

[0003] However, the above solution has the following shortcomings: in order to ensure the sealing between components and prevent dust or water from entering the module, the display module in the prior art often applies some sealing glue at the joints between components to prevent water or dust from entering the module. However, when the components in the module need to be repaired or replaced, due to the application of sealant, the operator needs to remove the residual glue after removing the component, so that there is no gap between the components after the repair is completed and the sealing glue is applied. This method is relatively cumbersome to operate. For this reason, we have introduced a display module structure and its back panel. Summary of the Invention

[0004] The object of the present invention is to provide a display module structure and a back plate thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A display module backplane comprises a front frame, a middle frame, and a rear plate. A transparent glass plate is fixedly mounted within the front frame. The middle frame is disposed inside the rear plate. The rear plate is disposed inside the front frame. Locking mechanisms are disposed around one side of the front frame and connected to the rear plate. An annular groove is formed within the front frame. A liquid storage mechanism is adhered within the annular groove to store sealing liquid. Several T-shaped push rods are disposed within the annular groove. The T-shaped push rod is movably connected to the inner side of the front frame, and one end of the T-shaped push rod away from the liquid storage mechanism is in contact with the locking mechanism. A sealing groove is opened on the outer side of the rear plate, and a pulling belt is pasted around the sealing groove. The upper end of the pulling belt is fixedly connected to the pull rod.

[0006] Preferably, the locking mechanism includes a movable plate, which is movably connected in a connecting groove, and the connecting groove is opened in one side of the front frame. The movable plate is fixedly connected to an extrusion rod and a plastic locking rod on the side close to the rear plate, and the plastic locking rod is clamped in the locking groove, and the locking groove is opened in the rear plate.

[0007] Preferably, the liquid storage mechanism includes an annular storage bag, a plurality of drainage ports are opened on the inner side of the annular storage bag, and baffles are attached to the drainage ports. When the T-shaped push rod squeezes the annular storage bag, the sealing liquid pushes the baffles open and is discharged from the drainage ports.

[0008] Preferably, the front frame is fixedly connected to a first limiting rod on all four sides of the inner side, the first limiting rod is clamped in a first limiting groove, the first limiting groove is opened on the outer side of the rear plate, and the rear plate is fixedly connected to a second limiting rod on all four sides of the inner side, the second limiting rod is clamped in a second limiting groove, and the second limiting groove is opened on the outer side of the middle frame.

[0009] Preferably, the extrusion rod is arranged in an arc shape at one end close to the T-shaped push rod, and the T-shaped push rod is arranged in an inclined shape at one end close to the extrusion rod.

[0010] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a display module structure, including the above-mentioned display module back plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses the arrangement of a liquid storage mechanism and a pulling belt, so that when the locking mechanism locks the front frame and the rear plate together, the T-shaped push rod squeezes the liquid storage mechanism, so that the sealing liquid enters the sealing groove, thereby sealing 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 pulling belt is driven to move by pulling the pull rod upward. The moving pulling belt pulls the solidified sealant out of the sealing groove, which is convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-6 , the present invention provides a technical solution: Example 1:

[0016] When the display screen is installed, the middle frame 2 is provided with a plurality of locking members 12, 13 and 14. The locking members 12 are connected to the front frame 1 and the rear frame 3 is connected to the front frame 1. When the display screen is installed, the middle frame 2 is provided with a plurality of locking members 12, 13 and 14. The locking members 12 are connected to the front frame 1 and the rear frame 3 is connected to the front frame 1. A T-shaped push rod 12 is movably connected to the inner side of the front frame 1. One end of the 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 outer side of the rear plate 3. A pull tape 9 is pasted around the sealing groove 10. A pull rod 19 is fixedly connected to the upper end of the pull tape 9. The front frame 1 is removed from the outer side of the rear plate 3. The pull tape 9 is moved by pulling the pull rod 19 upward. The movement of the pull tape 9 pulls out the sealing groove set in the sealing groove 10. When the pull tapes 9 are all pulled out, a new pull tape 9 is rewound and pasted in the sealing groove 10, and the new liquid storage mechanism is pasted in the annular groove 11. Example 2:

[0017] On the basis of Example 1, in order to facilitate the operator to clean the solidified sealing liquid, the locking mechanism includes a movable plate 4, which is movably connected to the connecting groove 14. The connecting groove 14 is provided in one side of the front frame 1. The movable plate 4 is fixedly connected to the side close to the rear plate 3 with an extrusion rod 13 and a plastic locking rod 15. The plastic locking rod 15 is snapped into the locking groove 16. The locking groove 16 is provided in the rear plate 3. Pressing the movable plate 4 downward causes the plastic locking rod 15 to be snapped into the locking groove 16. With the plastic locking rod 15 snapped into the locking groove 16, the front frame 1 and the rear plate 3 are limited and fixed together. At the same time, the extrusion rod 13 is driven to rotate during the movement of the movable plate 4. The extrusion rod 13 squeezes the T-shaped push rod 12 during the rotation process. The liquid storage mechanism includes an annular storage bag 20, which has a plurality of drainage ports 18 formed inside. Baffles 17 are attached to the drainage ports 18. When the T-shaped push rod 12 squeezes the annular storage bag 20, the sealing liquid pushes the baffles 17 aside and is discharged from the drainage ports 18. The T-shaped push rod 12 moves to squeeze the annular storage bag 20, causing the sealing liquid inside the annular storage bag 20 to enter the drainage ports 18. The baffles 17 located in the drainage ports 18 are pushed out, and the sealing liquid then enters the sealing groove 10, sealing the connection between the rear plate 3 and the front frame 1. The front frame 1 is fixedly connected to the first limiting rod 8 on all four sides of the inner side, and the first limiting rod 8 is clamped in the first limiting groove 7. The first limiting groove 7 is opened on the outer side of the rear plate 3. The rear plate 3 is fixedly connected to the second limiting rod 6 on all four sides of the inner side, and the second limiting rod 6 is clamped in the second limiting groove 5. The second limiting groove 5 is opened on the outer side of the middle frame 2.

[0018] The end of the extrusion rod 13 close to the T-shaped push rod 12 is arranged in an arc shape, and the end of the T-shaped push rod 12 close to the extrusion rod 13 is arranged in an inclined shape.

[0019] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a display module structure, including the above-mentioned display module back plate.

[0020] Working principle: When in use, press the middle frame 2 to the inner side of the back plate 3. Under the pressure of the middle frame 2, the second limiting rod 6 will be snapped into 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 inner side of the middle frame 2, wrap the pull tape 9 around and stick it to the bottom of the sealing groove 10, and stick the annular sealing bag 20 containing the sealing liquid into the annular groove 11. After the pasting is completed, the front frame 1 is sleeved on the outer side of the back plate 3. At this time, the first limiting rod 8 will be snapped into the first limiting groove 7, and 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 correspond to each other. Press the movable plate 4 downward so that the plastic locking rod 15 is snapped into the locking groove 16. With the plastic locking rod 15 snapped into the locking groove 16, the front frame 1 and the back plate 3 are limited and fixed together. At the same time, the movement of the movable plate 4 drives the squeezing rod 13 to rotate. The squeezing rod 13 squeezes the T-shaped push rod 12 during the rotation. 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 the annular storage bag 20 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, and the connection between the rear plate 3 and the front frame 1 is sealed. When parts need to be repaired, the movable plate 4 is pushed upward to disengage the plastic locking rod 15 from the locking groove 16, and the front frame 1 is removed from the outer side of the rear plate 3. The pulling rod 19 is pulled upward to drive the pulling belt 9 to move. The pulling belt 9 moves to pull out the solidified sealant set in the sealing groove 10. When the pulling belt 9 is pulled out, a new pulling belt 9 is rewound and pasted in the sealing groove 10, and a new annular storage bag 20 is pasted in the annular groove 11.

[0021] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
