The elastic member 12 provides an elastic force to urge the sealing member 11 to rotate about the hinge to abut the housing 21 and block the pinhole 211.

In an embodiment of the present application, The mobile terminal 200, also called a mobile communication terminal, refers to a computer device that can be used in mobile, including a mobile phone, a notebook, a tablet computer, a POS machine, and even an on-board computer. The specific structure will be described in detail below using the mobile terminal sealing structure 100 in a mobile phone. The existing mid-to-high-end mobile phone adopts a card holder type 23 card structure 23, and the card holder 24 is ejected by triggering the push rod 231, and the pinhole 211 is disposed on the mobile phone case 21, and can be used when the mobile phone card holder 24 needs to be ejected. The ejector pin 22 is inserted into the pinhole 211 and pushes the push rod 231 toward the inside of the mobile phone. The ejector pin 22 inserted into the pinhole 211 is pushed to drive the sealing member 11 away from the pinhole 211 and push the push rod 231. When the push rod 231 moves to the setting The phone tray 24 is triggered to pop up when the position is set. The seal 11 is abutted or disposed adjacent to the push rod 231, and the seal 11 is used to trigger the push rod 231 to eject the cassette 24. The seal 11 can be an integrally formed injection molded part for mass production. Of course, it can also be provided as a separate body, and the material of the sealing member 11 can also be other types, such as metal. The elastic member 12 is a structural member capable of generating elasticity. The elasticity of the elastic member 12 causes the sealing member 11 to open close to the one end of the pinhole, and the sealing member 11 returns to the initial position to be returned.

The technical solution of the present application is blocked by the end of the pinhole 211 by using the sealing member 11. When the sealing member 11 is away from the pinhole 211, the elastic force of the elastic member 12 needs to be overcome; when the sealing member 11 is close to the pinhole 211, the elasticity is obtained. The elastic force of the member 12 drives the sealing member 11 to rotate around the hinge to abut the housing and block the pinhole, thereby realizing the waterproof and dustproof function of the pinhole 211 of the mobile terminal, and effectively preventing other foreign objects from being removed from the outside. The pinhole 211 enters to avoid causing the functional failure of the main board inside the mobile terminal.

Further, one end of the sealing member 11 is connected with a connecting ear 111, and the connecting ear 111 is provided with a hinge hole 1111. The inner wall of the housing protrudes from the hinge shaft 212, and the hinge shaft 212 is inserted into the hinge hole 1111.

In the embodiment of the present application, the hinge shaft 212 and the housing 21 may be integrally molded, or may be separately provided from the housing 21, such as the hinge shaft 212 being screwed to the housing 21 or the like. The hinge shaft 212 is gap-connected to the hinge hole 1111, the hinge shaft 212 is stationary relative to the housing 21, and the seal 11 is rotated about the hinge shaft 212. Of course, the hinge shaft 212 can also be designed in other forms. For example, the hinge shaft 212 further includes an articulated sleeve. The hinge sleeve is sleeved outside the hinge shaft.

The elastic force is increased to drive the stability of the sealing member 1 during the rotation of the hinge shaft, while ensuring the overall thinness of the mobile phone casing 21, thereby making the whole machine thinner. The mounting groove limits and resists the elastic member 12. When the ejector pin leaves the sealing member 11, the elastic member 12 is inserted into one end of the mounting groove to abut against the groove wall of the mounting groove, and the elastic force generated by the elastic member 12 pushes the groove of the mounting groove. The wall, which drives the sealing member 11 to return, that is, approaches and abuts the side wall of the pinhole, enhances the tightness and stability of the mobile terminal sealing structure 100, and is convenient for disassembly and installation.

The sealing portion 112 is closely fitted to the inner wall of the groove to ensure a sealing effect.

The present application further provides a mobile terminal 200. Referring to FIG. 2 and FIG. 6 again, the mobile terminal 200 includes: a cover body; a housing 21 that is covered with the cover body, and the housing 21 is provided with a pinhole 211; a member 11, the sealing member 11 is hinged to the housing 21;

The elastic member 12 has one end connected to the sealing member 11 and the other end connected to the housing 21. The elastic member 12 provides an elastic force to drive the sealing member 11 to rotate around the hinge to abut the housing 21 and block the pinhole 211.

In the embodiment of the present application, the housing 21 of the mobile terminal 200 is covered with the cover body to ensure the sealing effect of the mobile terminal 200. The mobile terminal 200, also called a mobile communication terminal, refers to a computer device that can be used in mobile, including a mobile phone, a notebook, a tablet computer, a POS machine, and even an on-board computer. The specific structure will be described in detail below using the mobile terminal sealing structure 100 in a mobile phone. The existing mid-to-high-end mobile phone adopts a card holder type 23 card structure 23, and the card holder 24 is ejected by triggering the push rod 231, and the pinhole 211 is disposed on the mobile phone case 21, and can be used when the mobile phone card holder 24 needs to be ejected. The ejector pin 22 is inserted into the pinhole 211 and pushes the push rod 231 toward the inside of the mobile phone. The ejector pin 22 inserted into the pinhole 211 is pushed to drive the sealing member 11 away from the pinhole 211 and push the push rod 231. When the push rod 231 moves to the setting The phone tray 24 is triggered to pop up when the position is set. The seal 11 is abutted or disposed adjacent to the push rod 231, and the seal 11 is used to trigger the push rod 231 to eject the cassette 24. The seal 11 can be an integrally formed injection molded part for mass production. Of course, it can also be provided as a separate body, and the material of the sealing member 11 can also be other types, such as metal. The elastic member 12 is a structural member capable of generating elasticity. The elasticity of the elastic member 12 causes the sealing member 11 to open close to the one end of the pinhole, and the sealing member 11 returns to the initial position to be returned.
