Figure 2 The drawing is as follows Figure 1 Another perspective of the three-dimensional schematic diagram of the electronic device 10, in which Figure 2 The dustproof device 100 is also shown.

Figure 5 The drawing is as follows Figure 4 An exploded view of the dustproof device 100 for easy observation. Figure 6 The drawing is as follows Figure 4This is a side view of the dustproof device 100, with some components omitted for easier observation. The dustproof device 100 can be applied to electronic devices 10 (e.g., laptops, automotive screens, or televisions) containing panel devices (e.g., liquid crystal displays, organic light-emitting diode displays, etc.) to prevent dust or moisture from penetrating the interior of the electronic device 10, but this invention is not limited thereto. In some embodiments of this invention, the dustproof device 100 includes a positioning structure 110, a first elastic body 130, a second elastic body 150, a cover 170, an opening A, and an electronic component B disposed at the opening A. The following will describe in detail the relevant details of the dustproof device 100, its functions, and the technical problems it solves.
[0038] The positioning structure 110 is used to provide a reference position for the mounting of other components. In some embodiments, the positioning structure 110 may be part of the housing, frame, bracket, or other structural component of the electronic device 10. The positioning structure 110 may be made of a rigid material, such as plastic, metal, or alloy.
[0039] The first elastomer 130 is attached to the positioning structure 110. The first elastomer 130 is elastic and compressible, wherein the first elastomer 130 can deform under pressure to provide a sealing effect. The material of the first elastomer 130 may include elastic polymers such as foamed materials (e.g., polyurethane foam, silicone foam), rubber, or silicone.
[0040] The second elastic body 150 is disposed on top of the first elastic body 130. The second elastic body 150 also has elasticity and compressibility, and can deform under pressure to form a seal together with the first elastic body 130. Its material can be the same as or different from the elastic material of the first elastic body 130, such as foamed materials (e.g., polyurethane foam, silicone foam), rubber or silicone and other elastic polymers, etc., and this utility model is not limited thereto.
[0041] A cover 170 is disposed on top of the second elastic body 150. The cover 170 can be a housing, panel (such as a glass substrate or glass cover), top cover, or other covering component of the electronic device 10. After assembly, the cover 170 abuts against the second elastic body 150 and presses downwards, simultaneously applying pressure to both the first elastic body 130 and the second elastic body 150, causing them to compress and deform. In this assembled state, an opening A is located between the first elastic body 130 and the second elastic body 150; therefore, opening A is a space defined by the relative arrangement of the first elastic body 130 and the second elastic body 150.
[0042] At least a portion of electronic component B is located within opening A. In one application example, electronic component B may be a flexible printed circuit (FPC), such as a flexible board used to connect panel driving circuitry and panel substrate. Electronic component B passes through opening A formed by the first elastic body 130 and the second elastic body 150 and extends from the side of electronic device 10 to the back of electronic device 10.
[0043] In practical applications, the first elastic body 130 is first placed or attached to the positioning structure 110. Next, the second elastic body 150 is placed on top of the first elastic body 130. At this time, at least a portion of the electronic component B (e.g., a flexible circuit board) that needs to pass through this structure is positioned in the opening A region between the first elastic body 130 and the second elastic body 150. Finally, a cover 170 is placed over the second elastic body 150, and pressure is applied (e.g., by locking, snapping, or adhesive to secure the cover 170 to the second elastic body 150). The pressure of the cover 170 is simultaneously transmitted to both the second elastic body 150 and the first elastic body 130, causing them to compress and deform. Due to the elastic deformation of the first elastic body 130 and the second elastic body 150, they fit tightly against the upper and lower surfaces of the electronic component B and the surrounding area, thereby sealing the gap around the opening A and preventing dust or moisture from entering the electronic device 10.
[0044] In some embodiments, the body of the positioning structure 110 is the outer frame or housing of the electronic structure, and the positioning structure 110 further includes a protruding unit 111 and two receiving slots 113 located on its body. The protruding unit 111 and the two receiving slots 113 securely position the first elastic body 130 and the second elastic body 150 from multiple directions. The protruding unit 111 may be, for example, rectangular, square, trapezoidal, or other suitable polygonal structures. When the first elastic body 130 engages with the protruding unit 111, the protruding unit 111 is located below the first elastic body 130, providing upward support for the first elastic body 130. In addition, the two receiving slots 113 are elongated channels, and the two receiving slots 113 extend parallel to each other. When the first elastic body 130 engages with the two receiving slots 113, the two receiving slots 113 are located on opposite sides of the first elastic body 130 (e.g., the left and right sides of the first elastic body 130), thereby accommodating the first elastic body 130 between the two receiving slots 113 to achieve lateral positioning. This design, combining the protruding unit 111 and the receiving groove 113, not only effectively secures the first elastic body 130 but also simplifies the assembly process. In practical applications, the first elastic body 130 can be directly inserted into the space between the two receiving grooves 113 from above, with the protruding unit 111 serving as its bottom endpoint and support point. Furthermore, the two receiving grooves 113 can also be connected to the left and right sides of the second elastic body 150, thus allowing the left and right ends of the second elastic body 150 to be inserted into the two receiving grooves 113 respectively, achieving lateral positioning.
[0045] In some embodiments of this invention, the first elastic body 130 may include a wedge-shaped structure to enhance the sealing, thus the first elastic body 130 has a cross-sectional feature that is wider at the top and narrower at the bottom when viewed from the side (please refer to...). Figure 6 The portion below the cutoff angle 131 allows the second elastomer 150 to be securely disposed on top of the first elastomer 130. Furthermore, the first elastomer 130 may have a cutoff angle 131 (or a rounded corner) formed between its top and front sides. In practical applications, a portion of the electronic component B is disposed above the first elastomer 130, and another portion of the electronic component B is adjacent to the front of the first elastomer 130. The cutoff angle 131 is disposed in the area adjacent to and abuts the electronic component B. The cutoff angle 131 effectively provides sufficient space to prevent the first elastomer 130 from squeezing or interfering with the electronic component B, thereby improving the service life of the electronic component B.
[0046] In some embodiments, the second elastomer 150 may be designed in a dumbbell shape (also known as an H-shape), which facilitates the fitting of the second elastomer 150 into the two receiving slots 113. Because the ends of the second elastomer 150 are thicker and can withstand a greater pressure distribution under pressure, the ends of the second elastomer 150 can be securely connected to the ends of the two receiving slots 113 and the first elastomer 130. Furthermore, the narrower middle portion of the second elastomer 150, together with the lower first elastomer 130, helps to define the opening A to accommodate the electronic component B.
[0047] In some embodiments of this invention, the dustproof device 100 may further include two adhesive members 190 (at least one adhesive member 190), which are located on the positioning structure 110, while the cover 170 is located on the two adhesive members 190. Therefore, the two adhesive members 190 are engaged between the cover 170 and the positioning structure 110, thus securing both. Specifically, a second elastic body 150 is located between the two adhesive members 190, with opposite ends (left and right ends) of the second elastic body 150 laterally engaging the two adhesive members 190. In practical applications, the adhesive members 190 may include adhesive tape (e.g., double-sided tape) or adhesive-coated structural members, the purpose of which is to assist in fixing the position of the second elastic body 150 and provide additional excellent sealing function while strengthening the overall structural strength.
[0048] In some embodiments of this invention, the adhesive element 190 may be designed in a U-shape. This U-shaped adhesive element 190 may include two adhesive arms 191 and a groove between the two adhesive arms 191, which extend parallel to each other. The second elastomer 150 is located in the groove between the two adhesive arms 191 for reception. This structural configuration facilitates more precise positioning of the second elastomer 150 relative to the adhesive element 190 before or during assembly, and may allow for lateral support or constraint of the second elastomer 150 by the adhesive arms 191.
[0049] In some embodiments of this utility model, two adhesive members 190 are respectively disposed above two receiving grooves 113, and the groove between the two adhesive arms 191 can be aligned with the lower receiving groove 113, thereby the receiving groove 113 and the adhesive members 190 can jointly support the first elastic body 130 and / or the second elastic body 150. In addition, the vertical alignment of the receiving groove 113 with the adhesive members 190 facilitates the rapid assembly of the first elastic body 130 and the second elastic body 150 onto the positioning structure 110 and the adhesive members 190, thus saving assembly time and increasing assembly accuracy.
[0050] In some embodiments of this invention, the compressibility of the first elastomer 130 and the second elastomer 150 may be designed to be superior to that of the adhesive 190. In other words, the adhesive 190 is relatively stiff or difficult to compress, while the first elastomer 130 and the second elastomer 150 are relatively soft or easier to compress. This design ensures that the main compression deformation occurs in the first elastomer 130 and the second elastomer 150, thereby effectively utilizing the elasticity of the first elastomer 130 and the second elastomer 150 to achieve the sealing function, while the adhesive 190 mainly plays a role in fixing, supporting, or assisting in the sealing, rather than being the primary compression sealant.
[0051] With the above structure, the first elastic body 130 and the second elastic body 150 of the dustproof device 100 of this utility model undergo elastic deformation under the pressure of the cover 170, effectively forming an opening A for accommodating the electronic component B. The first elastic body 130 and the second elastic body 150 are tightly attached to the electronic component B to achieve excellent dustproof effect.
[0052] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
