Description

A sealing ring assembly structure and electronic equipment Technical Field

[0001] This application relates to the field of sealing ring technology, specifically to a sealing ring assembly structure and electronic device. Background Technology

[0002] In existing technologies, the assembly has assembly holes. To prevent external dust and foreign objects from entering the assembly holes, a sealing ring coaxially positioned with the assembly hole needs to be bonded to the surface of the assembly to protect the assembly hole. However, existing sealing rings are directly bonded to the planar surface of the assembly. During assembly, it is difficult to accurately attach the sealing ring to the assembly, and it is easy to attach it crookedly. This not only affects the sealing effect but may also block the assembly hole, seriously affecting the product yield.

[0003] Therefore, it is necessary to provide an easy-to-assemble sealing ring assembly structure and electronic device. Technical issues

[0004] The purpose of this application is to provide a sealing ring assembly structure and electronic device to solve the technical problem that sealing rings are difficult to assemble accurately in the prior art. Technical solutions

[0012] Along the direction away from the limiting groove, the first through hole sequentially includes a first hole segment and a second hole segment. The hole wall of the first hole segment is a cylindrical surface, and the diameter of the first hole segment is equal to the diameter of the second through hole. The hole wall of the second hole segment is a frustum surface. Along the direction away from the limiting groove, the diameter of the second hole segment gradually increases.

[0013] Preferably, the top surface of the ring body is exposed in the limiting groove.

[0031] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0032] This application provides a sealing ring assembly structure 10, including an assembly body 1 and a sealing ring 2, as shown in Figures 1 to 9. The assembly body 1 includes a main body 101 and a limiting protrusion ring 102, which protrudes from the main body 101. The limiting protrusion ring 102 and the main body 101 together form a limiting groove 103. A first through hole 104 is provided on the main body 101, which communicates with the limiting groove 103. The sealing ring 2 is housed in the limiting groove 103. The sealing ring 2 includes a ring body 201 and an adhesive layer 202, which is fixed to the bottom surface of the ring body 201. The ring body 201 is bonded and fixed to the bottom surface 1031 of the limiting groove 103 by the adhesive layer 202. When the ring body 201 is fixed in the limiting groove 103, the side surface 2011 of the ring body 201 abuts against the groove wall of the limiting groove 103. The sealing ring 2 also includes a second through hole 203, which penetrates the ring body 201 and the adhesive layer 202, and is coaxially arranged with the first through hole 104.

[0033] In this embodiment, the limiting protrusion 102 of the assembly 1 and the main body 101 together form a limiting groove 103. The ring body 201 of the sealing ring 2 is bonded and fixed to the bottom surface 1031 of the limiting groove 103 by the adhesive layer 202. The side surface 2011 of the ring body 201 abuts against the groove wall of the limiting groove 103, so that the second through hole 203 and the first through hole 104 can be effectively aligned and coaxially set. This can effectively avoid poor sealing effect or even failure to seal caused by the sealing ring 2 being misaligned. It can also effectively avoid the sealing ring 2 blocking the first through hole 104, which would prevent the assembly 1 from being effectively assembled with other environmental components. It is not only easy to assemble, but also accurate to assemble, improving the sealing effect, assembly efficiency and product yield.

[0034] In some preferred embodiments, the limiting groove 103 includes a first groove segment 1032 and a second groove segment 1033 sequentially along the direction from the groove opening to the bottom of the groove, as shown in Figures 4 and 6. The groove wall of the first groove segment 1032 is a frustum. Furthermore, the diameter of the first groove segment 1032 gradually decreases along the direction from the groove opening to the bottom of the groove, thereby facilitating the installation of the sealing ring 2 into the limiting groove 103. The groove wall of the second groove segment 1033 is a cylindrical surface. The side surface 2011 of the ring body 201 is a cylindrical surface, and the side surface 2011 of the ring body 201 abuts against the groove wall of the second groove segment 1033, thereby ensuring a sealing effect.

[0035] In some preferred embodiments, referring to Figures 8 and 9, the wall of the second through hole 203 is cylindrical. Referring to Figure 7, along the direction away from the limiting groove 103, the first through hole 104 sequentially includes a first hole segment 1041 and a second hole segment 1042. The wall of the first hole segment 1041 is cylindrical, and the diameter of the first hole segment 1041 is equal to the diameter of the second through hole 203, thereby further improving the sealing effect and not interfering with the assembly 1 being assembled with other environmental components through the first through hole 104. The wall of the second hole segment 1042 is frustum-shaped, and the diameter of the second hole segment 1042 gradually increases along the direction away from the limiting groove 103, thereby facilitating the assembly 1 being assembled with other environmental components through the first through hole 104.

[0036] In some preferred embodiments, as shown in Figures 2 and 7, when the ring body 201 is fixed in the limiting groove 103, the top surface 2012 of the ring body 201 is exposed in the limiting groove 103. That is, the height of the sealing ring 2 is greater than the depth of the limiting groove 103, which facilitates the assembly operation and allows the sealing ring 2 to be more securely fixed in the limiting groove 103.

[0037] In some preferred embodiments, the ring 201 can be made of silicone, which is not only easy to assemble but also provides a good seal and a long service life. It should be noted that in other embodiments, the ring 201 can also be made of other materials, which will not be elaborated here.

[0038] In some preferred embodiments, referring to FIG7, the ring body 201 includes a first corner rounded surface 2013 extending between the side surface 2011 and the bottom surface of the ring body 201. The ring body 201 having the first corner rounded surface 2013 makes it easier to install the sealing ring 2 into the limiting groove 103, thus improving assembly efficiency.

[0039] Accordingly, referring to Figures 4 and 7, the assembly 1 has a second corner rounded surface 1034 extending between the groove wall of the limiting groove 103 and the groove bottom surface 1031 of the limiting groove 103. The second corner rounded surface 1034 abuts against the first corner rounded surface 2013, which allows the sealing ring 2 to fit more tightly with the limiting groove 103, thereby improving the sealing effect.

[0040] In some preferred embodiments, the adhesive layer 202 is double-sided tape, which is not only low in cost, easy to use, and easy to assemble, but also effectively fixes the ring 201 to the assembly 1. It should be noted that in other embodiments, the adhesive layer 202 may also be other adhesives, which will not be elaborated here.

[0041] In some preferred embodiments, referring to Figures 1, 3, and 5, the assembly 1 includes multiple limiting protrusions 102, each of which, together with the main body 101, forms a limiting groove 103. That is, the number of limiting grooves 103 is equal to the number of limiting protrusions 102. The main body 101 has multiple first through holes 104, each corresponding to a limiting groove 103. The sealing ring assembly structure 10 includes multiple sealing rings 2, each corresponding to a limiting groove 103, with each sealing ring 2 installed within its corresponding limiting groove 103. As an example, when installing the sealing rings 2 into the assembly, automated equipment can be used for automated assembly, allowing multiple sealing rings 2 to be assembled at once, thereby improving production efficiency.

[0042] This application also provides an electronic device including any of the sealing ring assembly structures 10 described above.

[0043] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
