Background

Currently, electronic devices are often configured with keys. In general, a key is mounted on a middle frame of an electronic device. Because electronic devices are integrated with more and more electronic components, the space in the shell of the electronic device is more and more restricted, and the installation of keys is inconvenient. For this reason, the current push button is generally an externally-mounted push button, that is, the push button is assembled by being mounted from the outside of the housing to the center frame.

As shown in fig. 1, in this case, a hanging hole 1011 is formed in the middle frame 101 of the housing, hanging parts 1021 are disposed at both ends of the key 102, the hanging parts 1021 at both ends of the key 102 extend into the hanging position of the middle frame 101 through the hanging hole 1011, in this case, the hanging part 1021 at one end of the key 102 is directly hung on the edge of the inner port of the hanging hole 1011, and the hanging part 1021 at the other end of the key 102 needs to be positioned by the fixing member 103 mounted on the middle frame 101, so as to realize the hanging installation of the end. The existing electronic equipment is provided with all-metal keys, and as the keys 102 are hung on the middle frame 101, a large assembly space is reserved in the middle frame 101, so that the keys 102 can be conveniently and obliquely installed. In this case, the middle frame 101 of the electronic apparatus needs to cut out a large area. This results in a lower strength of the middle frame 101 and ultimately in a lower strength of the housing, which is more susceptible to deformation.

Of course, the exterior-mounted key 102 is not limited to be mounted on the middle frame 101, and may be mounted on other parts of the housing, in which case the strength of the housing of the electronic device is still poor.
