In this embodiment, the soft rubber member 24 and the hard rubber frame 22 are integrally formed by injection molding, and in other embodiments, the soft rubber member and the hard rubber frame may be attached by an adhesive layer.
Also referring to fig. 3, optionally, in an embodiment, a groove 246 is formed on a side of the combining portion 242 facing away from the side key 40, and the side key switch 30 is accommodated in the groove 246. Due to the arrangement, the side key switch 30 can be attached to the soft rubber piece 24 more closely, so that a user can control the side key switch 30 without using a larger pressing force.
Further, with reference to fig. 6 and 7, in an embodiment, the soft rubber 24 forms a concave portion 248 toward the side key 40 and a peripheral portion 244 surrounding the concave portion 248, and forms a protrusion 2482 at a position where the concave portion 248 is attached to the side key 40. The bump 2482 is clamped between the side key 40 and the side key switch 30, and the bump 2482 enables the force pressed by the user to be mostly directly applied to the bump 2482 when the user presses the side key 40, so that the force can be better applied to the side key switch 30, and the user has better hand feeling when pressing the side key 40. In other embodiments, the side of the soft rubber 24 facing the side key 40 may be only a plane, or other surfaces, as long as the force applied to the side key 40 can act on the side key switch 30.
The side key 40 is fastened on the inner wall of the main board upper cover 10 surrounding the side key groove 142, so that the side key 40 is detachably connected to the appearance part 14, and a part of the side key 40 is located in the side key groove 142, attached to the soft rubber part 24, and arranged opposite to the side key switch 30. Specifically, the side key 40 has engaging portions 42 at both ends thereof, and the engaging portions 42 are used to engage and connect the side key 40 to the inner wall of the surrounding side key groove 142. In other embodiments, the side keys 40 can be riveted or glued to the inner wall of the surrounding side key holes 142.
Further, in an embodiment, the side key 40 is formed with a protrusion 44 toward the side key switch 30, and the protrusion 44 is closely attached to the soft rubber piece 24 and is disposed opposite to the side key switch 30. This arrangement enables the side key switch 30 to be controlled by the user by pressing the side key 40 slightly.
In one embodiment, the waterproof assembly 100 further includes a seal 50, and the seal 50 is formed on the side of the soft rubber piece 24 facing the side key 40. By adopting the structure, the whole waterproof part 20 can be tightly attached to the inner wall of the enclosing containing groove 122, good air tightness is ensured, and the mobile terminal device applied to the waterproof assembly 100 is ensured to have better waterproof performance at the position of the side key 40. It will be appreciated that in embodiments where the soft glue 24 forms a recess 248 on the side facing the side key 40 and a peripheral portion 244 that encloses the recess 248, the seal 50 is formed on the peripheral portion 244. When the waterproof member 20 is accommodated in the accommodating groove 122 of the main board upper cover 10, the end surface of the sealing member 50 far away from the side key switch 30 is closer to the side key 40 than the end surface of the protruding block 2482 far away from the side key switch 30, so as to ensure that the flexible glue member 24 is in seamless fit with the inner wall surrounding the accommodating groove 122, thereby further improving the waterproof performance of the waterproof assembly 100. In the above embodiment, the seal 50 is an annular seal ring, and in another embodiment, the seal 50 may have a non-sealing shape having an opening.
It is understood that the seal 50 is integrally formed with the cushion member 20 by injection molding in one embodiment. This can make the sealing member 50 and the soft rubber member 20 be more firmly combined.
