Insert the pressing assembly 90 into the operating groove 47. Specifically, insert the side of the key body 92 glued with the connecting glue 96 into the operating groove 47, and the guide surface 945 slidably presses against the inner circumference of the operating groove 47, and the sealing rib 944 seals against the inner circumference of the operating groove 47 until the outer side surface 921 of the key body 92 is roughly coplanar with the side surface 405 of the shell 40, and the connecting glue 96 is connected to the side of the first elastic part 642 away from the pressure sensing element 62; at this time, the first plate body 651 of the flexible circuit board 65 and the pressure sensing element 62 are both located in the avoidance groove 453, and the key body 92 is attached to the first elastic part 642 through the connecting glue 96, and the connection The distances between the opposite ends of the glue 96 and the opposite ends of the side walls of the avoidance groove 453 are respectively the first elastic wall length E1 and the second elastic wall length E2. The first elastic wall length E1 and the second elastic wall length E2 can be adjusted by adjusting the length and position of the connecting glue 96; the bending piece 655 is accommodated in the avoidance groove 453 and the overflow glue groove 4533, and the second plate body 653 is located outside the mounting groove 45; the second plate body 653 of the flexible circuit board 65 is inserted into the through hole 48, and the second plate body 653 and the bending piece 655 of the flexible circuit board 65 are connected to the shell 40 through pressure-sensitive adhesive, and the connector 656 of the flexible circuit board 65 is plugged into the connector of the main board 42.Insert the wire management member 82 into the through hole 48 from the back of the housing 40, so that the wire management member 82 locates the bending portion 6535 of the flexible circuit board 65, and the two snap-fit ​​blocks 823 are respectively snapped on the two snap-fit ​​platforms 482 to prevent the wire management member 82 from falling off from the through hole 48; apply glue to the side of the waterproof cover 73 away from the waterproof support frame 72 and between the waterproof ring 732 and the inner circumference of the installation groove 45. The glue will fill the space between the support portion 722 and the inner circumference of the installation groove 45 and the circumference of the bending piece 655 under the action of its own fluidity, and the glue will Water is filled to the overflow glue groove 4533, and the glue forms a waterproof part 74 after solidification. The waterproof part 74 can achieve a high-level waterproof effect; glue is applied to the back and surrounding of the wire management part 82, and the glue will fill the space between the wire management part 82 and the inner circumference of the via 48, as well as the space around the bending piece 655 due to its own fluidity. The glue forms a sealing cover 84 after solidification. The sealing cover 84 is sealed and filled between the wire management part 82 and the inner circumference of the via 48, as well as in the avoidance gap 484. The sealing cover 84 can achieve a high-level waterproof effect.

[0068] When the pressure sensing module 60 is assembled to the mounting groove 45, both elastic members 63 are deformed. Driven by the deformation of the first abutting piece 635, the first elastic piece protrusion 6352 will slide against the second inner side surface 452 of the mounting groove 45. Driven by the deformation of the second abutting piece 636, the second elastic piece protrusion 6362 will slide against the second side surface 646 of the connecting member 64. During this process, the elastic member 63 generates a reverse force on the connecting member 64 and drives the first elastic portion 642 to deform. When the pressure sensing module 60 is assembled to the mounting groove 45, the rebound force generated by the deformation of the elastic member 63 causes the elastic member 63 to slide against the second inner side surface 452 of the mounting groove 45, so that the pressure sensing module 60 is stably fixed to the mounting groove 45.

[0069] Since the two elastic parts 63 elastically press against the opposite ends of the second inner side surface 452 of the mounting groove 45 respectively, the pressure sensing module 60 is ensured to be stably positioned in the mounting groove 45, and the first elastic part 642 is opposite to the avoidance groove 453, which is convenient for the elastic deformation of the first elastic part 642; the waterproof cover 73 and the waterproof part 74 on the waterproof support frame 72 are both sealed against the inner circumferential surface of the mounting groove 45, thereby realizing double waterproofing of the pressure sensing module 60, and the waterproof effect is good and stable.

[0070] 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 first elastic part 642 of the connecting part 64, so that the first elastic part 642 is deformed. The pressure sensing part 62 on the flexible circuit board 65 senses the micro deformation of the first elastic part 642, and then generates resistances and electrical signals of different sizes. 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, so as to realize the recognition and grading of the user's pressing force, which corresponds to different application scenarios and camera functions, etc.

[0071] The connector 64 of the pressure sensing module 60 of the present application is directly positioned in the mounting groove 45 of the shell 40 through the elastic member 63, and there is no need to use another mechanism to position the pressure sensing module 60 in the shell 40, that is, the pressure sensing module 60 only includes a connector 64 and a flexible circuit board 65, and two elastic members 63 welded to the opposite ends of the connector 64. Therefore, the pressure sensing module 60 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 mounting groove 45 from the operating groove 47 and affecting the deformation and function of the connector 64; 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 key body 92 and the operating groove 47 from the outside. In addition, it is only necessary to directly insert the waterproof support frame 72 into the installation groove 45, and the two elastic members 63 respectively press against the inner side surfaces of the installation groove 45 so that the pressure sensing module 60 can be firmly positioned on the shell 40; the pressing component 90 is directly inserted into the operating groove 47 and connected to the pressure sensing module 60, and the assembly is simple, reliable and low-cost.
