As shown in fig. 6-8, the mount 7 for fixedly connecting the first end of the touch pad assembly 3 to the housing 2 may take a variety of forms in specific implementations. In some embodiments, the first end of the touch pad assembly 3 may extend outward to form a connection portion 8, the fixing member 7 may be a pin 9, and the connection portion 8 may be pinned to the housing 2 of the electronic device by the pin 9. For example, a rectangular opening may be opened on the housing 2 of the electronic device, the touch pad assembly 3 is correspondingly disposed at the rectangular opening, two rectangular connecting pieces for forming the connecting portion 8 may be symmetrically disposed at the first end of the supporting board 4, the connecting pieces protrude from the edge of the first end of the touch pad assembly 3, pin holes are disposed on the connecting pieces, the two connecting pieces may abut against the housing 2 from the inner side, and the pin shaft 9 penetrates through the pin holes of the connecting pieces and is pinned to the housing 2, so as to fix the first end of the touch pad assembly 3 to the housing 2.

It is understood that the fixing member 7 is not limited to the above structure, but may be, for example, a snap structure, an adhesive structure or other types of connecting structures, as long as the touch pad assembly 3 and the housing 2 can be fixedly connected. It should be noted that the fixing member 7 is used to fixedly connect the first end of the touch pad assembly 3 and the housing 2, but the fixing member 7 is not limited to be disposed at the first end of the touch pad assembly 3. Taking the rectangular touchpad assembly 3 as an example, the fixing member 7 may be connected to an edge of one side as the first end, or may be connected to the first side and the second side near the first end, so as to fix the first end of the touchpad assembly 3 and the housing 2.

It will be appreciated that the resilient support member 10 is not limited to including the first and second resilient support arms 15, 16, and may include more resilient support arms, or may include other resilient members.
In the implementation process, as shown in fig. 7 and 8, a mounting position 17 may be provided on the housing 2 near the second end of the touch pad assembly 3, and the mounting position 17 is used for mounting the elastic supporting member 10. In this case, the first and second resilient support arms 15, 16 each extend in opposite directions from the mounting location 17. Specifically, the mounting position 17 may be a bar-shaped protrusion protruding from the housing 2 to the bottom of the second end of the touch pad assembly 3, and the bar-shaped protrusion may be flat. When the housing 2 is a plastic housing 2, the strip-shaped protrusion can be integrally formed with the housing 2 to improve the structural strength thereof. The elastic support member 10 can be fixedly connected to the mounting position 17 by a pin joint, a rivet joint, or a snap joint.
In one embodiment, the middle portion of the elastic supporting member 10 is fixedly connected to the housing 2, one end of the elastic supporting member 10 extends toward the first side of the touch pad assembly 3 and bends toward the touch pad assembly 3 to form a first elastic supporting arm 15, and the other end of the elastic supporting member 10 extends toward the second side of the touch pad assembly 3 and bends toward the touch pad assembly 3 to form a second elastic supporting arm 16. For example, the elastic support member 10 may include a bar-shaped elastic sheet, and a plurality of through holes may be formed in a middle portion of the bar-shaped elastic sheet along a length direction thereof and may be riveted to the bar-shaped protrusion portion by rivets penetrating the through holes or riveting snaps provided on the bar-shaped protrusion portion. The both ends of bar shell fragment can be followed the second end of touch pad subassembly 3 and extended to first side and second side direction respectively, still buckle to touch pad subassembly 3 when extending, until the butt in the bottom of touch pad subassembly 3. As shown in fig. 4, as a preferred embodiment, the spherical protrusion 20 is disposed on the first elastic supporting arm 15 and/or the second elastic supporting arm 16, and the first elastic supporting arm 15 and/or the second elastic supporting arm 16 abuts against the touch pad assembly 3 through the spherical protrusion 20, so that when the touch pad assembly 3 is pressed, the spherical protrusion 20 and the touch pad assembly 3 can slide smoothly and relatively, and jamming is not easy to occur.
In another embodiment, the elastic support member 10 includes a first elastic piece and a second elastic piece; one end of the first elastic sheet is fixedly connected with the shell 2, and the other end of the first elastic sheet extends to the first side of the touch pad component 3 and is bent towards the touch pad component 3 to form a first elastic supporting arm 15; one end of the second elastic sheet is fixedly connected with the shell 2, and the other end of the second elastic sheet extends towards the second side of the touch pad assembly 3 and bends towards the touch pad assembly 3 to form a second elastic supporting arm 16. For example, the first elastic sheet and the second elastic sheet can be metal elastic sheets, one end of the first elastic sheet is opposite to one end of the second elastic sheet, the opposite ends are sequentially provided with two through holes along the length direction, and the opposite ends are pinned at the bottoms of the strip-shaped protruding parts through pin shafts penetrating through the through holes. The other end of first shell fragment extends to first side direction, and the other end of second shell fragment extends to second side direction to the two pastes to touch pad subassembly 3's bottom gradually and leans on, until the butt on touch pad subassembly 3.
As shown in fig. 8, in some embodiments, the mounting location 17 and the touchpad assembly 3 may have a gap therebetween, and the detection unit 11 may be disposed within the gap. When the touch panel assembly 3 is pressed, the gap changes, for example, the gap gradually decreases until the touch panel assembly is attached, or the gap decreases to a preset threshold, and the detection unit 11 can be triggered to generate an input signal, and based on different actions of the pressing operation, the detection unit 11 can generate different input signals, such as single click, double click, long press, and the like.
In a specific implementation process, as shown in fig. 9, the detection unit 11 includes a detection switch 12 and a contact 13, the detection switch 12 may be disposed at a bottom center line of the touch panel assembly 3, and the contact 13 is used for triggering the detection switch 12 when the pressing portion is pressed, so that the detection switch 12 generates an input signal. The detection switch 12 may be a dome switch which is provided on the base plate 5 and protrudes downward, and has a dome structure 14 made of metal, and a notch is provided at a corresponding position on the support plate 4 so that the dome structure 14 can protrude from the support plate 4 through the notch. The contacts 13 may be provided on mounting locations 17, such as spherical bumps provided on the top of the strip-shaped projections. When the touchpad assembly 3 swings in the left-right direction with the center line thereof as the axis line, the contact 13 can abut on the dome structure 14 or form a gap with the dome structure 14.
In this case, portions of the pressing portions on both sides of the detection switch 12 may form a first pressing portion and a second pressing portion, respectively. For example, the first pressing portion may be a portion near the first side of the touchpad assembly 3, and the second pressing portion may be a portion near the second side of the touchpad assembly 3. The first elastic supporting arm 15 can provide an elastic feedback force for the first pressing portion, and the second elastic supporting arm 16 can provide an elastic feedback force for the second pressing portion. When the first pressing portion is pressed, the contact 13 abuts on the dome structure 14 of the detection switch 12 at a position close to the first side, and when the second pressing portion is pressed, the contact 13 abuts on the dome structure 14 of the detection switch 12 at a position close to the second side. By detecting the position at which the dome 14 is pressed by the contact 13, the pressing position of the pressing operation can be determined, and thus different input signals can be generated. For example, when a first pressing portion is pressed, the detection switch 12 can generate an input signal that is relatively far from the left mouse button, and when a second pressing portion is pressed, the detection switch 12 can generate an input signal that is relatively far from the right mouse button. Of course, the pressing portion is not limited to include the first pressing portion and the second pressing portion, and may include, for example, a third pressing portion located in the middle between the first pressing portion and the second pressing portion.
It should be noted that the detection unit 11 is not limited to the above-described structure, and the mounting position 17 of the detection unit 11 is not limited to between the touch panel assembly 3 and the housing 2. In another embodiment, the detection unit 11 may include a detection sensor, which may be disposed on the touch panel assembly 3, may be capable of detecting a pressure applied to the touch surface of the touch panel assembly 3, and may be capable of generating an input signal based on the detected pressure. For example, a pressure detection layer may be provided on the touch surface of the touch panel assembly 3, the pressure detection layer may be capable of detecting a position and a pressure magnitude pressed by a user when the touch panel assembly 3 is pressed by a finger or the like of the user, and when the pressure of the pressing operation is greater than a preset pressure threshold, the pressing operation may be determined to be a valid pressing operation, and then an input signal may be generated based on the pressing position of the pressing operation. The detection sensor may be, for example, one or more capacitive sensors or electromagnetic sensors provided between the touch panel assembly 3 and the housing 2, and by detecting a change in the posture of the touch panel assembly 3, the pressing position of the pressing operation can be determined, and different input signals can be generated based on the pressing position.
