Referring to fig. 1 to 4, an embodiment of the present invention provides a triggering structure, including: the button comprises a button body 1, wherein a buckle assembly is arranged on the button body 1; the step provided with the stepped through hole 21 and the through hole 21 is used for bearing the key body 1, the step is provided with a groove portion 22 corresponding to a buckle assembly of the key body 1 so as to enable the buckle assembly to be clamped on the shell 2, the step is provided with a first bearing surface opposite to the bottom surface of the key body 1 and a second bearing surface opposite to the side surface of the key body 1, a waterproof layer 3 is arranged between the first bearing surface and the bottom surface of the key body 1, and the side surface of the waterproof layer 3 is tightly attached to the second bearing surface.

The key body 1, that is, the portion that the user needs to press the contact, specifically can adopt the shape that the convenience of the user pressed the use such as circular, square, in order to guarantee life, the key body 1 can adopt Acrylonitrile (A) -Butadiene (B) -Styrene (S) terpolymer (ABS, Acrylonitrile Butadiene Styrene plastics) or Polycarbonate (PC, Polycarbonate) etc. kind plastics, and the durability is good, difficult damage, drop, long service life, optionally, be in before the key body 1 is pressed under the state of resetting or setting, the upper surface of key body 1 and the upper surface parallel and level of casing 2, in order to guarantee the aesthetic property of trigger structure outward appearance and press the feel.

Referring to fig. 1, the key body 1 is provided with a fastening component, and the fastening component needs to be correspondingly fastened to the groove portion 22 on the step, so the fastening component is usually disposed on the end surface of the key body 1 opposite to the through hole 21, and of course, the fastening component may also be disposed at other positions according to the specific position of the groove portion 22, for example, the fastening component is fixed on the side surface of the key body 1.

Specifically, buckle subassembly can adopt colluding the shape structure, barb shape structure etc. can the joint be fixed in the structural shape of concave part 22, buckle subassembly and button body 1 can the formula structure as an organic whole, one-time machine-shaping, the cost is lower, of course, also can adopt split type structure, conveniently change or maintain buckle subassembly, and is optional, for convenience of buckle subassembly joint in concave part 22, buckle subassembly need have certain deformability, the user can be through pressing etc. mode make buckle subassembly produce certain deformation and pass through concave part 22 and joint in the bottom of concave part 22.

In some alternative embodiments, the catch assembly includes at least a first catch 11 and a second catch 12 disposed opposite each other, and the recessed portion 22 includes at least a first recess and a second recess corresponding to the first catch 11 and the second catch 12, respectively. The first buckle 11 and the second buckle 12 are respectively clamped on the first groove and the second groove,

optionally, the first buckle 11 and the second buckle 12 are symmetrical about the center of the key body 1 to improve the stability of the key body 1 when being fixed on the housing 2, and certainly, the buckle assembly may further include more buckles, for example, a third buckle, and the first buckle 11, the second buckle 12 and the third buckle are distributed on the key body 1 in a regular triangle shape, so that the stability during fixing is better as long as the setting form of the key body 1 can be effectively fixed.
