The third waterproof component 84 can achieve a high-level waterproof effect.

[0080] The first positioning rib 763, the second positioning rib 765 and the third positioning rib 754 are staggered with a reasonable gap to ensure that when the size of the shell 40 fluctuates, the amount of extrusion between the first positioning rib 763, the second positioning rib 765 and the third positioning rib 754 and the inner side surface of the installation groove 45 will not make the waterproof frame 72 unable to be assembled to the shell 40. In addition, the two first positioning ribs 763 respectively conflict with the first inner side surface 451, and the second positioning rib 765 and the third positioning rib 754 respectively conflict with the second inner side surface 452, and the first positioning rib 763, the second positioning rib 765 and the third positioning rib 754 are staggered at a reasonable distance from each other, so that the first positioning rib 763 and the second positioning rib 765 of the waterproof frame 72 can use their own deformation after being subjected to the conflicting force to push the third positioning rib to the inner side surface of the mounting groove 45, thereby ensuring that there is a reasonable deformation space between the elastic connecting piece 644 of the pressure sensing module 60 and the inner side surface of the mounting groove 45; at the same time, a reasonable locking amount is set between the clamping block 761 and the clamping groove 4542 to prevent the waterproof frame 72 from falling off during falling and normal use, resulting in poor waterproofing. The backing glue 96 is glued between the key body 92 and the pressing plate 646, and the sealing rib 944 is sealed against the inner circumference of the operating groove 47 to prevent the key body 92 from falling out; two anti-mistake parts 926 are provided on the key body 92 to avoid the front and back sides being installed upside down when assembling the pressing component 90.

[0081] When using the button 50 of the electronic device 100, the user presses the outer side surface 921 of the button body 92, and the button body 92 transmits the pressure to the pressing piece 646. The pressing piece 646 squeezes the connecting piece 644 to deform. The pressure sensing element 640 on the flexible circuit board 65 generates an electrical signal after sensing the deformation. The flexible circuit board 65 is connected to the main board 42 through the connector 656, and transmits the electrical signal to the processor on the main board 42, thereby realizing the recognition and grading of the user's pressing force, which corresponds to different application scenarios and camera functions.

[0082] The pressure sensing module 60 of the button 50 of the present application is directly positioned on the waterproof frame 72, and there is no need to use another mechanism to position the pressure sensing module 60 on the housing 40. Therefore, the button 50 saves components, reduces material costs, and has a simple structure, reducing manufacturing costs. Secondly, a reasonable interference amount is set between the sealing ring 94 and the inner circumference of the operating groove 47 to prevent dust or foreign matter from entering the installation groove 45 from the operating groove 47 and affecting the deformation and function of the connecting piece 644; and a dust collecting groove 947 is set on the outer circumference of the sealing ring 94, and the dust collecting groove 947 is used to accommodate foreign matter entering the gap between the button body 92 and the operating groove 47 from the outside. In addition, it is only necessary to directly insert the waterproof frame 72 into the installation groove 45, and the first positioning rib, the second positioning rib and the third positioning rib are respectively pressed against the inner circumference of the installation groove 45, so that the waterproof frame 72 can be firmly positioned on the housing 40; the pressing component 90 is directly inserted into the operating groove 47 and combined with the pressure sensing module 60, and the assembly is simple and reliable, and the cost is low.

[0083] The above is an implementation of the embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the embodiment of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
