When the connecting piece 64a is connected to the two connecting feet 76, the elastic section 643 faces the avoidance space 762. In other embodiments, the positioning section 645 and the connecting foot 76 can also be fixedly connected by, but not limited to, welding or screwing.
[0092] like Figure 44-Figure 47As shown, when assembling the pressure sensing module 60a, the first board 651 of the flexible circuit board 65 is connected to the side of the connecting member 64a away from the escape space 762 by means of the hot pressing adhesive 68. The clamping posts 761 of the two connecting legs 76 are respectively clamped to the two positioning holes 642 of the connecting member 64a, and each connecting leg 76 is glued to the corresponding positioning section 645 by means of the connecting adhesive 763, so that the pressure sensing module 60a is fixedly connected to the waterproof mechanism 70, and the elastic section 643 faces the escape space 762.
[0093] like Fig.39 and Figure 48-Figure 49As shown, when assembling the button to the housing 40, the waterproof support frame 72 and the pressure sensing module 60a are plugged into the mounting groove 45 of the housing 40. Specifically, the two connecting legs 76 and the connecting member 64a are inserted into the mounting groove 45 together, so that the two abutting portions 760 are respectively slidably pressed against the first inner side surface 451, until the fixing glue 767 at the bottom of the two connecting legs 76 are respectively glued to the bottom surface of the mounting groove 45, and the two clamping blocks 766 are respectively clamped to the clamping grooves at the opposite ends of the mounting groove 45; there is a reasonable interference amount between the elastic convex bump 7605 and the first inner side surface 451, and the rebound force of the abutting portion 760 allows the waterproof support frame 72 to push against the first inner side surface 451. The two positioning sections 645 of the connecting member 64a respectively abut against the second inner side surface 452, so that the waterproof support frame 72 and the pressure sensing module 60a are firmly positioned in the mounting groove 45 of the shell 40; the elastic section 643 is opposite to the avoidance groove 453, and the pressure sensing component 62 is accommodated in the avoidance groove 453, and there is a gap between the pressure sensing component 62 and the inner side surface of the avoidance groove 453, so that the elastic section 643 and the pressure sensing component 62 have a certain elastic deformation space, and the thickness of the deformation space mainly depends on the height difference between the inner side surface of the avoidance groove 453 of the shell 40 and the second inner side surface 452, as well as the thickness of the first plate 651 and the hot pressing adhesive 68. Insert the side of the button body 92 glued with the adhesive backing 96 into the operating groove 47 until the outer side surface of the button body 92 is roughly coplanar with the side surface of the shell 40, and the adhesive backing 96 is connected to the elastic section 643 of the connecting piece 64a; 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 button body 92 is attached to the connecting piece 64a through the adhesive backing 96; 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 cable management frame 82 into the through hole 48 from the back side of the shell 40 so that the cable management frame 82 positions the flexible circuit board 65 to prevent the cable management frame 82 from falling off from the through hole 48; apply glue between the side of the second waterproof part 78 away from the waterproof support frame 72 and the inner circumference of the mounting groove 45. The glue will fill the space between the waterproof support frame 72 and the inner circumference of the mounting groove 45 and the space around the bending piece 655 due to its own fluidity, and the glue will fill the overflow groove 4524. After the glue is cured, a waterproof part 74 is formed, and the waterproof part 74 can achieve a high-level waterproof effect; apply glue on the back and around the cable management frame 82. The glue will fill the space between the cable management frame 82 and the inner circumference of the through hole 48 due to its own fluidity. After the glue is cured, a waterproof cover 84 is formed. The waterproof cover 84 is sealed and filled between the cable management frame 82 and the inner circumference of the through hole 48. The waterproof cover 84 can achieve a high-level waterproof effect.
[0094] Since the two abutting portions 760 elastically abut against the opposite ends of the first inner side surface 451 of the mounting groove 45, the pressure sensing module 60 is ensured to be stably positioned in the mounting groove 45, and the elastic section 643 is opposite to the avoidance groove 453, which is convenient for the elastic deformation of the elastic section 643; the second waterproof component 78 and the waterproof component 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.
[0095] When the user presses the outer side of the button body 92, the button body 92 transmits the pressure to the elastic segment 643 of the connecting piece 64a, causing the elastic segment 643 to deform. The pressure sensing element 62 on the flexible circuit board 65 senses the micro-deformation of the elastic segment 643, thereby generating resistances and electrical signals of different sizes. The flexible circuit board 65 is connected to the main board through the connector 656, and transmits the electrical signal to the processor on the main board, thereby realizing the recognition and grading of the user's pressing force, which corresponds to different application scenarios and camera functions, etc.
[0096] Compared with the pressure sensing module 60 in the first embodiment, the pressure sensing module 60a in the second embodiment only requires a connector 64a and a flexible circuit board 65, which saves multiple components and reduces the manufacturing cost; the opposite ends of the connector 64a are directly fixedly connected to the two connecting feet 76 of the waterproof mechanism 70, and the fixing scheme of the connector 64a and the connecting feet 76 is similar to the scheme in the first embodiment. An escape space 762 is provided between the two connecting feet 76, and an escape groove 453 facing the elastic section 643 is provided in the middle of the second inner side surface 452 of the mounting groove 45, so that the elastic section 643 and the pressure sensing element 62 have a certain elastic deformation space, and the size of the deformation space mainly depends on the height difference between the escape groove 453 of the shell 40 and the second inner side surface 452 of the mounting groove 45, as well as the thickness of the first plate body 651 of the flexible circuit board 65 and the hot pressing adhesive 68. The button body 92 is adhered to the elastic section 643 through the adhesive backing 96. The distances between the opposite end edges of the hot pressing adhesive 68 and the opposite end side walls of the avoidance groove 453 are respectively the first elastic wall length and the second elastic wall length. The first elastic wall length and the second elastic wall length can be adjusted by adjusting the length and position of the adhesive backing 96.
[0097] 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.
