Description

Technical Field

[0001] This utility model relates to the field of mobile terminal technology, and in particular to a walkie-talkie button structure. Background Technology

[0002] In the walkie-talkie industry, standard products have side buttons. To achieve a waterproof rating, the side buttons are often fixed to the housing using silicone buttons and adhesive. However, the adhesive application process requires an adhesive application machine, fixtures, labor, and adhesive consumption, as well as curing time, resulting in low production efficiency. Furthermore, the waterproof effect is greatly affected by the adhesive application process, and the consistency of mass production is affected by the adhesive application process, which can easily lead to defective products.

[0003] Traditional P+R buttons use glue to bond the plastic keycaps and key liner together. Some also use double-shot injection molding or double injection molding to combine the two into one piece, which is more expensive and cannot meet the requirements for waterproof design. In addition, the P+R buttons are pressed by hand, so the feel is not delicate enough and the user experience is poor.

[0004] Therefore, engineers in this field need to further improve the button structure and develop a walkie-talkie button structure that is simple in structure, easy to assemble, waterproof, efficient in production, low in cost, and provides a good user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a walkie-talkie button structure that is simple in structure, easy to assemble, waterproof, efficient in production, low in cost, and provides a good user experience.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A walkie-talkie button structure includes: a housing and button bodies. The housing contains a main control PCB board with multiple dome switches. The housing has multiple button holes, and the button bodies are correspondingly disposed within these button holes and movably connected to the dome switches. Each button body includes a silicone rubber button and a button liner. The silicone rubber button has a cavity structure. The outer side of each silicone rubber button has a first limiting flange and a groove circumferentially arranged. The button liner is semi-embedded in the silicone rubber button and is interference-fitted to it. The inner side of each button hole has a lip protrusion that matches the corresponding groove. The button bodies and the corresponding button holes form a dustproof and waterproof sealing structure.

[0008] In the above structure, the lip protrusion is circumferentially protruding inside the button hole, and the lip protrusion divides the button hole into a first receiving cavity and a second receiving cavity. The first receiving cavity is disposed adjacent to the inner side of the outer shell, and both the first receiving cavity and the second receiving cavity are limiting groove structures with an L-shaped cross section.

[0009] In the above structure, the first limiting flange is arranged circumferentially along the bottom edge of the silicone rubber button, and the first limiting flange and the groove are respectively matched with the corresponding first receiving cavity and the lip boss. The first limiting flange and the groove are respectively embedded in the first receiving cavity and the lip boss, and the silicone rubber button is movably connected to the outer shell.

[0010] In the above structure, the button liner includes a pressing post, an elastic arm, and a frame. The pressing post is vertically arranged in the middle of the frame. The pressing post is a circular or non-circular structure. The pressing post is connected to the frame through the elastic arm to form a support structure with a rebound function.

[0011] In the above structure, the button liner matches the silicone rubber button, the top circumferential of the button liner is chamfered, and the bottom outer side of the button liner is provided with a second limiting flange, which matches the first limiting flange.

[0012] In the above structure, the button body can be any shape, including round, oval, and square, and the button body matches the corresponding button hole.

[0013] In the above structure, the silicone rubber button has an abutment part inside that matches the button liner, and multiple silicone rubber buttons can abut against the dome button through the corresponding pressing post.

[0014] In the above structure, the silicone rubber button is made of thermoplastic elastomer material by hydraulic molding.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention improves the structure of the silicone rubber button, button liner, and corresponding button hole. A lip protrusion is provided inside the button hole, and multiple lip protrusions on the inner side of the button hole correspond to grooves on the outer circumferential side of the silicone rubber button. The button liner is embedded inside the silicone rubber button, eliminating the need for adhesive application and allowing direct pressing, thus improving production and assembly consistency. Utilizing the properties of silicone rubber and plastic, the interference fit between the plastic shell and the liner frame forms effective compression and rigid support for the silicone button, achieving waterproofing and dustproofing. This invention features a simple structure, convenient assembly, good waterproofing, high production efficiency, and low cost, greatly enhancing the user experience. Attached Figure Description
