Sealing structure and display device

Abstract

A sealing structure and a display device that combine sealing properties and convenience are provided. [Solution] The sealing structure includes a first connecting portion (10), a second connecting portion (20), and a sealing member. The sealing member is located between the first connecting portion and the second connecting portion. The sealing member includes an attachment portion (35) and a movable portion, which are connected to each other in order. The attachment portion is provided on the first connecting portion, and the movable portion abuts against the second connecting portion. When the first connecting portion and the second connecting portion move toward each other, the second connecting portion and the attachment portion together drive the movable portion to wind up a portion of the attachment portion, forming a winding sealing block (34). As the winding sealing block rolls relative to the attachment portion or the second connecting portion, the resistance force of the winding sealing block against the attachment portion and the second connecting portion becomes smaller. As the movable portion rolls, the cross-sectional area of the winding sealing block gradually increases, and both sides of the winding sealing block abut against the other portion of the attachment portion and the second connecting portion, respectively.

Description

[Technical Field]

[0001] This application claims priority from a Chinese application bearing application number 202423301926.2, filed with the China Patent Office on December 27, 2024, and incorporates all of the contents of that application by reference.

[0002] The present invention relates to the technical field of display devices, and more particularly to a sealing structure and a display device. [Background technology]

[0003] Outdoor displays can be placed outdoors and still function as a display, so they are widely used for posting outdoor advertisements and displaying outdoor electronic content. The key to ensuring stable operation of outdoor displays over a long period of time is whether their waterproof performance is stable.

[0004] Current outdoor displays typically consist of a housing and multiple display modules, requiring a waterproof seal between the housing and the display modules. Conventional waterproof seals are divided into two types: a front-side waterproof structure, in which a seal is installed along the mounting direction of the display module and the housing. As the display module moves toward the housing along the mounting direction, it compresses the sealing rubber ring between the display module and the housing. To achieve a stronger seal, the compressive force between the display module and the housing is relatively large. This typically requires screws to fasten the display module to the housing, which precludes the use of a magnetic adsorption mechanism for easy removal of the display module. The other type is a side-side waterproof structure, in which a seal (e.g., a sealing ring) is installed perpendicular to the mounting direction of the display module and the housing. As the display module moves toward the housing along the mounting direction, the sealing ring inevitably moves relative to the display module (or housing). To achieve a stronger seal, the sliding friction between the sealing ring and the display module (or housing) becomes very large, making it very difficult to remove the display module from the housing. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to overcome the shortcomings of the prior art, the present utility model aims to provide a sealing structure and a display device to solve the problem that the current waterproof sealing structure between the display module and the housing is difficult to achieve both sealing performance and ease of removal.

[0023] To facilitate understanding of the present invention, the present invention will now be described more fully with reference to the accompanying drawings. While the drawings show preferred embodiments of the present invention, the present invention may be realized in many different forms and is not limited to the embodiments described herein. Rather, the purpose of providing these embodiments is to provide a more complete understanding of the disclosure of the present invention.

[0024] It should be noted that when an element is described as being "fixed" to another element, the element may be directly attached to the other element, or there may be an intermediate element between them. When an element is described as being "connected" to another element, the element may be directly connected to the other element, or there may be an intermediate element between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for descriptive purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of this utility model. The terms used in the description of this utility model in this specification are for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this specification includes any and all combinations of the associated listed elements.

[0026] Example 1 As shown in a combination of Figures 1, 2, 5 and 6, the sealing structure of the present utility model is shown schematically, and the sealing structure includes a first connecting portion 10, a second connecting portion 20, and a sealing member 30 located between the first connecting portion and the second connecting portion.

[0027] The sealing member 30 includes a holding portion 31, a connecting portion 32, and a movable portion 33, which are connected in this order. The movable portion 33 is disposed opposite the holding portion 31, which is disposed on the first connecting portion 10. The holding portion 31 serves to fix the sealing member 30 and ensures that the connecting portion 32 and the movable portion 33 maintain their original positions and postures when not subjected to external force. The movable portion 33 abuts against the second connecting portion 20. When the sealing member 30 is disposed between the first connecting portion 10 and the second connecting portion 20, one side of the movable portion 33 abuts against the holding portion 31. When the sealing member 30 is not disposed between the first connecting portion 10 and the second connecting portion 20 (for example, when only the sealing member 30 is removed), there is a gap between the movable portion 33 and the holding portion 31.

[0028] 5 and 6, when the first connecting part 10 and the second connecting part 20 move toward each other, the second connecting part 20 and the holding part 31 drive the movable part 33 to wind, and the wound movable part 33 winds up the connecting part 32 to form the winding sealing block 34. Referring to Fig. 6, both sides of the winding sealing block 34 are abutted against the holding part 31 and the second connecting part 20, respectively, and the winding sealing block 34 and the holding part 31 move in a rolling manner, generating rolling friction, while the winding sealing block 34 and the second connecting part 20 also move in a rolling manner, generating rolling friction. Rolling friction produces a smaller frictional force than the sliding friction generated by conventional sealing structures, which results in a smaller resistance to movement of the winding sealing block 34 relative to the holding portion 31 and the winding sealing block 34 relative to the second connecting portion 20; in other words, a smaller force is required to drive the first connecting portion 10 and the second connecting portion 20 to move toward each other.

[0029] As the first connecting portion 10 and the second connecting portion 20 continue to move toward each other, the cross-sectional area of the winding sealing block 34 gradually increases, and both sides of the winding sealing block 34 come into contact with the holding portion 31 and the second connecting portion 20, respectively. On the other hand, if the distance between the first connecting portion 10 and the second connecting portion 20 remains unchanged, the compressive force between the winding sealing block 34 and the holding portion 31 and the compressive force between the winding sealing block 34 and the second connecting portion 20 gradually increase, thereby providing better sealing for the first connecting portion 10 and the second connecting portion 20. Of course, in this embodiment, the sealing member 30 is made of rubber or silicone material, which allows the connecting portion 32 to be wound and stretched. Furthermore, since one side of the winding sealing block 34 abuts the holding portion 31, the compressive force of the winding sealing block 34 against the holding portion 31 will also cause some deformation of the holding portion 31.

[0030] Furthermore, the first connecting part 10 is provided with a mounting groove 11, the holding part 31 is fitted into the mounting groove 11, and the holding part 31 and the mounting groove 11 are connected by an interference fit method, so that the connection between the holding part 31 and the mounting groove 11 does not require any additional fasteners, thereby reducing the material cost of the sealing structure and simplifying the manufacturing process of the sealing structure. In addition, due to the compressive force of the winding sealing block 34 on the holding part 31, the holding part 31 tends to move toward the bottom of the mounting groove 11, thereby making the connection between the holding part 31 and the mounting groove 11 stronger and preventing the holding part 31 and the mounting groove 11 from being unintentionally separated.

[0031] The second connecting part 20 has a sealing surface 21 arranged opposite the opening of the mounting groove 11, and the movable part 33 abuts against the sealing surface 21. When the first connecting part 10 and the second connecting part 20 move toward each other, the holding part 31 and the sealing surface 21 drive the movable part 33 to wind, and both sides of the winding sealing block 34 abut against the holding part 31 and the sealing surface 21, respectively.

[0032] The connecting portion 32 has a first surface 321 and a second surface 322 arranged opposite to each other, and a movable portion 33 is provided on the first surface 321 of the connecting portion 32. Of course, since the sealing member 30 has an integrally molded structure and the movable portion 33 located at the end of the connecting portion 32 protrudes beyond the first surface 321 of the connecting portion 32, this structure enables one side of the movable portion 33 to abut against the holding portion 31 and the other side of the movable portion 33 to abut against the sealing surface 21 of the second connecting portion 20. The second surface 322 of the connecting portion 32 is arranged opposite to the holding portion 31, and the movable portion 33 is provided on the first surface 321 of the connecting portion 32. As a result, when the first connecting portion 10 and the second connecting portion 20 move toward each other, the connecting portion 32 provides the movable portion 33 with a predictable winding direction, which helps the movable portion 33 to smoothly wind up the connecting portion 32 and form the wound sealing block 34.

[0033] The cross section of the movable part 33 is preferably circular, which allows the movable part 33 to wind under the drive of the holding part 31 and the second connecting part 20, thereby contributing to winding up the connecting part 32 connected to the movable part 33.

[0034] Example 2 1 and 2, Example 2 differs from Example 1 in that, in Example 2, one end of connecting portion 32 is provided at one end of holding portion 31, and connecting portion 32 extends toward that end of holding portion 31, so that the cross section of the combination of connecting portion 32 and holding portion 31 forms a V shape, and movable portion 33 is provided at the other end of connecting portion 32. As a result, when sealing member 30 is not installed between first connecting portion 10 and second connecting portion 20 (for example, when only sealing member 30 is removed), a gap can be created between movable portion 33 and holding portion 31. When sealing member 30 with this structure is positioned between first connecting portion 10 and second connecting portion 20, connecting portion 32 allows one side of movable portion 33 to abut against second connecting portion 20.

[0035] Example 3 3 and 4, the difference between Example 3 and Example 1 is that in Example 3, the holding part 31 has a leading end 311 and a trailing end 312, the trailing end 312 of the holding part 31 is connected to the connecting part 32, the thickness of the holding part 31 gradually increases along the direction from the leading end 311 to the trailing end 312, and the movable part 33 is installed opposite the leading end 311 of the holding part 31. As a result, when the first connecting part 10 and the second connecting part 20 start to move toward each other, the compressive force between the winding sealing block 34 and the holding part 31 and the compressive force between the winding sealing block 34 and the second connecting part 20 are relatively small due to the holding part 31 having a relatively small thickness, and the first connecting part 10 and the second connecting part 20 are pulled. As they continue to move toward each other, the movable part 33 winds the connecting part 32, gradually increasing the cross-sectional area of the formed winding sealing block 34. The winding sealing block 34 moves to the middle and then to the end 312 of the holding part 31 (the thickness of the holding part 31 also gradually increases). The resistance of the winding sealing block 34 to the first connecting part 10 and the second connecting part 20 also gradually increases. This resistance allows the operator to judge the winding size and winding degree of the winding sealing block 34 by feeling the resistance, providing a certain degree of force feedback and improving the user experience when attaching the first connecting part 10 and the second connecting part 20. Also, referring to FIGS. 7 and 8, as the first connecting part 10 and the second connecting part 20 move away from each other (separate from each other), the movable part 33 must gradually return to the end 311 of the holding part 31. Because the thickness of the end 312 of the holding part 31 is greater than the thickness of the end 311, the return resistance of the movable part 33 can be reduced. Preferably, a slope or a recess is provided at the tip 311 of the holding part 31, so that the movable part 33 can be accurately returned to the initial position of the tip 311 of the holding part 31, ready for the next winding.

[0036] Example 4 1 and 2, the difference between Example 4 and Example 3 is that in Example 4, the retaining portion 31 is annular, the inner wall of the retaining portion 31 is inclined relative to the axis of the retaining portion 31, and the hole diameter of the tip 311 of the retaining portion 31 is smaller than the hole diameter of the end 312 of the retaining portion 31. As a result, after the retaining portion 31 is installed in the mounting groove 11, the bottom of the mounting groove 11 is a circumferential surface, so the retaining portion 31 installed in the mounting groove 11 will be deformed. The compressive force between the tip 311 of the retaining portion 31 and the mounting groove 11 is greater than the compressive force between the end 312 of the retaining portion 31 and the mounting groove 11. As a result, the tensile force generated by the tip 311 of the retaining portion 31 is greater and the thickness of the tip 311 of the retaining portion 31 is smaller, which further improves the user experience when installing the first connecting portion 10 and the second connecting portion 20.

[0037] Example 5 As shown in Figures 9 to 11, the difference between Example 5 and Example 1 is that in Example 5, the sealing structure includes a first connection portion 10, a second connection portion 20, and a sealing member 30 located between the first connection portion 10 and the second connection portion 20.

[0038] The sealing member 30 includes an attachment portion 35 and a movable portion 33. The attachment portion 35 is provided on the first connecting portion 10, and the movable portion 33 is adapted to abut against the second connecting portion 20. The attachment portion 35 has a first end 351 and a second end 352 arranged oppositely, and the movable portion 33 is arranged on the first end 351 of the attachment portion 35. When the first connecting portion 10 and the second connecting portion 20 move toward each other, the movable portion 33 winds up a portion of the attachment portion 35 to form a winding sealing block 34, and both sides of the winding sealing block 34 abut against the attachment portion 35 and the second connecting portion 20, respectively. Specifically, the movable portion 33 winds up from the first end 351 of the attachment portion 35 to the middle of the attachment portion 35 to form the winding sealing block 34, and both sides of the winding sealing block 34 abut against the second end 352 of the attachment portion 35 and the second connecting portion 20, respectively.

[0039] The first connecting portion 10 has a mounting groove 11, and the second connecting portion 20 has a sealing surface 21 arranged opposite the opening of the mounting groove 11. The mounting portion 35 is fitted into the mounting groove 11. Specifically, the first end 351 of the mounting portion 35 abuts against one end of the mounting groove 11, and the second end 352 of the mounting portion 35 abuts against the other end of the mounting groove 11. The movable portion 33 is used to abut against the sealing surface 21.

[0040] Furthermore, a receiving recess 111 is provided in the bottom wall of the mounting groove 11, and the receiving recess 111 is located at one end of the bottom wall of the mounting groove 11. A smooth transition may be formed between the inner wall of the receiving recess 111 and the bottom wall of the mounting groove 11. When the mounting part 35 is installed in the mounting groove 11, one side of the first end 351 of the mounting part 35 is installed facing the opening of the receiving recess 111, and at this time, a part of the movable part 33 is fitted into the receiving recess 111. When the first connecting part 10 and the second connecting part 20 move away from each other, the first end 351 of the mounting part 35 is released from the winding seal block 34, and the movable part 33 finally rolls down into the receiving recess 111. Due to the installation of the receiving recess 111, after the first connecting part 10 and the second connecting part 20 move away from each other, the movable part 33 is accommodated in the receiving recess 111, allowing the mounting part 35 to fully recover and prepare for the next winding.

[0041] Example 6 As shown in Figures 12 to 14, the difference between Example 6 and Example 5 is that in Example 6, the thickness of the first end 351 of the mounting portion 35 is made smaller than the thickness of the second end 352 of the mounting portion 35 in order to reduce the return resistance of the movable portion 33.

[0042] Example 7 As shown in Figures 5 to 15, Example 7 provides a display device, which includes a housing 40, a display module 50, and the above-mentioned sealing structure, and one of the first connection part 10 and the second connection part 20 is installed in the housing 40, and the other is installed in the display module 50.

[0043] As described above, the sealing member is located between the first connecting portion 10 and the second connecting portion 20, and the sealing member 30 includes an attachment portion 35 and a movable portion 33 which are connected to each other in order, the attachment portion 35 is provided on the first connecting portion 10, and the movable portion 33 is used to abut against the second connecting portion 20. As a result, when the first connecting portion 10 and the second connecting portion 20 move toward each other, the second connecting portion 20 and the attachment portion 35 together drive the movable portion 33 to wind up and take up a part of the attachment portion 35, thereby forming a wound sealing block 34. As the winding sealing block 34 rolls and moves relative to the mounting part 35 or the second connecting part 20, the resistance force of the winding sealing block 34 against the mounting part 35 and the second connecting part 20 becomes smaller, and as the movable part 33 rolls, the cross-sectional area of the winding sealing block 34 gradually increases, and both sides of the winding sealing block 34 abut against the other part of the mounting part 35 and the second connecting part 20, respectively, thereby providing better sealing performance.

[0044] The above description is merely an example of the present utility model and does not limit the scope of the present utility model registration claims. Any modifications of the equivalent structure or equivalent process made based on the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, will also fall within the scope of the present utility model registration claims.
