Further, the camera 20, the emergency help key 30 and the camera decoration 40 are all disposed on the back of the mobile terminal 100 with the emergency help key. The emergency help-seeking key 30 is also arranged on the back of the mobile terminal 100, so as to prevent the emergency help-seeking key 30 from being confused with other keys of the mobile terminal, and facilitate the old to find the emergency help-seeking key 30 quickly and easily identify and press the emergency help-seeking key 30.

Further, the camera 20 and the emergency help-seeking key 30 are vertically aligned. Because mobile terminal's inside device is more, and the mobile terminal back generally sets up appearance radian design, consequently, will camera 20 with emergency call for help button 30 all sets up the position placed in the middle at the mobile terminal back, just camera 20 with emergency call for help button 30 is vertical direction and aligns the setting, avoids taking horizontal space, helps optimizing mobile terminal's inner space as far as possible.

In this embodiment, preferably, the camera 20 is disposed at an end of the emergency call-for-help key 30 close to the top of the mobile terminal. That is, the camera 20 is disposed above the distress key 30. Because the camera 20 needs to cooperate with the flat cable inside the mobile terminal and the printed circuit board, the convenience and the photographing effect when the camera 20 is used need to be considered, and therefore the camera 20 is arranged at one end of the top of the mobile terminal, which is closer to the emergency help key 30.

In order to protect the camera 20, the camera garnish 40 is generally provided around the camera 20. Camera decoration 40 can reduce camera 20 is stained with the fingerprint, and is simultaneously bellied camera decoration 40 can also be in mobile terminal's collision in-process protection the camera. Specifically, the camera decoration 40 is made of a metal piece or a plastic piece. In this embodiment, the camera decoration 40 is used to protect not only the camera 20 but also the distress key 30.

The camera decoration 40 includes a camera hole for receiving the camera 20 and an emergency key hole for receiving the emergency key 30, wherein the camera holes may be provided in plural, and are provided according to the number of the cameras 20. In this embodiment, the number of the cameras 20 is one, and therefore, the camera decoration 40 includes a camera hole and an emergency key hole. The distance between the camera hole and the emergency help key hole is smaller than the edge width of the camera decoration part, so that the camera decoration part 40 can reduce the structural distance between the camera 20 and the emergency help key, the internal space of the mobile terminal 100 is optimized, and the portable design of the mobile terminal 100 is realized.

Further, the emergency help-seeking key 30 provided by the utility model comprises a key cap 31, a key conductive base 32 and a DOME elastic sheet 33 which are arranged from top to bottom, wherein the key conductive base 32 is used for pressing and abutting against the DOME elastic sheet 33 and conducting, and the DOME elastic sheet 33 is used for abutting against the printed circuit board to realize a key function.

Specifically, the shape and structure of the key cap 31 are set according to the connection relationship with the key conductive base 32 or the emergency help key hole. When the key cap 31 is connected with the emergency help-seeking key hole in a pressing manner, the key cap 31 is of a convex structure or a circular structure, and the maximum radius of the key cap 31 is larger than that of the key hole, so that the key cap 31 cannot completely extend out of the key hole, and the emergency help-seeking key is convenient to press. When the key cap 31 is connected with the key conductive base 32 in a pressing manner, the maximum radius of the key cap 31 is smaller than the radius of the key hole, so that the key cap 31 can completely extend out of the key hole, and the extended section of the key conductive base 32 is matched with the camera decorating part 40 for pressing and fixing. In this embodiment, the key cap 31 is a circular structure, and the operation of the emergency help key 30 is realized by pressing the key cap 31 to push the key conductive base 32 to move forward.
