[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figures 1-3A fully sealed metal insert for a mobile phone includes an insert body 1, with sealing edges 2 around its surface and a first contact 3 at the top of the sealing edges 2; a groove 4 is formed at the bottom of the insert body 1, and an elastic sheet 5 is disposed inside the groove 4, with a first contact block 6 and a second contact block 7 respectively at the top and bottom of the elastic sheet 5. The sealing edges 2 provide a preliminary sealing effect, preventing external dust, moisture, and other impurities from entering the mobile phone, protecting the internal electronic components from damage, improving the phone's waterproof and dustproof performance, and extending the phone's lifespan. The first contact 3 contacts the tactile switch of the volume buttons inside the phone, providing a buffering and stable contact. The first contact 3 is made of rubber. The contact 3 has a certain degree of elasticity, which can buffer pressure during button operation and avoid excessive impact on the tactile switch. On the other hand, it can ensure good contact with the tactile switch, ensure the normal triggering of the volume button function, and improve the sensitivity and reliability of button operation. The setting of the elastic piece 5 enables a good elastic connection between the first contact block 6 and the second contact block 7. When the volume button switch on the surface of the phone casing is pressed, the second contact block 7 will be subjected to pressure, the elastic piece 5 will undergo elastic deformation, and the pressure will be transmitted to the first contact block 6, thereby making the first contact block 6 contact with the first contact 3, and finally triggering the tactile switch inside the phone. This elastic connection method can provide better button feel and feedback, while ensuring the stability and accuracy of button operation.
[0022] Furthermore, the first contact 3 and the sealing edge 2 are made of rubber. Rubber has good elasticity and sealing properties. For the first contact 3, the elasticity of the rubber can better adapt to the contact with the tactile switch, providing appropriate pressure and cushioning, reducing wear and noise. For the sealing edge 2, the flexibility of the rubber can closely fit the relevant internal structure of the mobile phone, effectively blocking the intrusion of external substances, further enhancing the sealing performance of the mobile phone. Moreover, the cost of rubber is relatively low, and it is easy to process and mold, which helps to reduce production costs and improve production efficiency.
[0023] Furthermore, the elastic sheet 5 is U-shaped, and the inner wall of the elastic sheet 5 is fixedly connected to the fixing post 8, which is also fixedly connected to the inner wall of the groove 4. The U-shaped design of the elastic sheet 5 gives it good elastic deformation ability, allowing it to easily deform under pressure and quickly return to its original shape after the pressure is removed, ensuring the repeated operation performance of the button. The fixing post 8 reinforces the elastic sheet 5, preventing it from shifting or deforming during frequent deformation, ensuring a stable connection between the elastic sheet 5 and the inner wall of the groove 4, thereby ensuring the reliability and stability of the entire button triggering mechanism.
[0024] Furthermore, the bottom end of the insert body 1 is provided with a sealing element for sealing the groove 4, and the surface of the sealing element is symmetrically provided with second contact elements that contact the second contact block 7. The sealing element can further seal the groove 4, prevent dust, moisture and other substances from entering the groove 4, protect key components such as the elastic sheet 5, the first contact block 6 and the second contact block 7 from the influence of the external environment, and improve the reliability and durability of the entire insert. The second contact element contacts the volume button switch on the surface of the mobile phone shell and is connected to the second contact block 7. It can play the role of transmitting pressure, accurately transmitting the pressure of the button switch to the second contact block 7, ensuring the effective triggering of the button operation, and also playing a certain role in buffering and stabilizing the contact, improving the button's user experience.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
