In some implementations, the two pressure sensor assemblies 200 are symmetrical about the center of the printed circuit board 100. Illustratively, two pressure sensor assemblies 200 are axisymmetrical about the center of the printed circuit board 100, e.g., two pressure sensor assemblies 200 are axisymmetrical about a second centerline O of the printed circuit board 100 ₂ Is axisymmetric; illustratively, the two pressure sensor assemblies 200 are symmetrically rotated 180 degrees about the center of the printed circuit board 100, and are arranged such that the fixed position of one of the flexible connection arms 211 to the printed circuit board 100 is located in the lower half area of the printed circuit board 100, as shown in the drawing, and the fixed position of the flexible connection arm 211 to the left side of the printed circuit board 100 is located on the first center line O ₁ The lower half region of (a); such that the other flexible connecting arm 211 is fixed to the printed circuit board 100 at the upper half area of the printed circuit board 100, as shown in the figure, and the right flexible connecting arm 211 is fixed to the printed circuit board 100 at the first center line O ₁ The upper half of (1). With such an arrangement, the integrity of the touch pad is further improved, so that the vibration acting force of the vibration feedback device 110 is transmitted to the surface of the touch pad through the flexible connecting arm 211, and the consistency of vibration feedback is further improved.

With reference to fig. 2 and fig. 3, the pressure sensor assembly 200 of the embodiment of the present application includes an elastic support 210 and a pressure sensor 220, where the elastic support 210 is used to support the pressure sensor 220 and drive the pressure sensor 220 to elastically deform together when the touch pad is pressed, so that the pressure sensor 220 can detect the pressure applied to the touch pad.

The piezoresistive pressure sensor comprises four variable resistors which are interconnected to form a Wheatstone bridge detection circuit, and the resistance change is converted into a corresponding electric signal (voltage or current) through the detection circuit to be output, so that the process of converting the pressure into the electric signal is completed.

The touch pad provided by the embodiment of the application, including printed circuit board 100 and elastic support 210, skew central point puts and is provided with vibration feedback device 110 on edge printed circuit board 100, its elastic support 210 includes flexible link arm 211, the second end and the printed circuit board 100 fixed connection of flexible link arm 211, and flexible link arm 211 can follow vibration feedback device 110's vibration feedback direction elastic deformation, when vibration feedback device 110 produces the vibration, the vibration power makes flexible link arm 211 warp and transmits other regions to printed circuit board 100 through flexible link arm 211, thereby make the whole vibration of touch pad, and make the vibration power deviation in the touch pad region reduce, improve vibration feedback's uniformity.

With continued reference to fig. 2 and 3, the elastic support 210 of the embodiment of the present application includes a flexible connecting arm 211 and a cantilever 212, the cantilever 212 has a fixed end and a free end, the fixed end of the cantilever 212 is fixed to the housing of the electronic device by a screw, and is fixed relative to the touch pad when under pressure, which is referred to as the fixed end; the free end of the cantilever 212 is suspended with respect to the housing of the electronic device and elastically deforms with respect to the touch pad when under pressure, referred to as the free end. The pressure sensor 220 is disposed at the free end of the cantilever 212, and the free end of the cantilever 212 is elastically connected to the first surface of the reinforcing plate 300. Illustratively, an elastic element 240 is bonded to the free end of the cantilever 212 to elastically support the touch pad. The resilient element 240 is proximate to the free end of the cantilever 212 and the pressure sensor 220 is closer to the fixed end of the cantilever 212 than the resilient element 240. The elastic element 240 may be a silicone pad.

Thus, when the touch pad is pressed, the pressure is transmitted to the cantilever 212 through the elastic element 240 on the cantilever 212, and the cantilever 212 is elastically deformed, so that the pressure sensor 220 attached to the cantilever 212 is deformed to detect the pressure applied to the cantilever 212.

The flexible arm 211 has a first end and a second end opposite to each other, the first end of the flexible arm 211 is connected to the cantilever 212, and the first end of the flexible arm 211 of the embodiment of the present application is directly connected to the fixed end of the cantilever 212. The second end of the flexible connecting arm 211 is fixedly connected with the reinforcing plate 300. Thus, the printed circuit board 100 is integrated with the elastic bracket 210 by the flexible connection arm 211.

Moreover, the flexible connecting arm 211 can elastically deform along the vibration feedback direction of the vibration feedback device 110, so that when the touch controller 120 drives the vibration feedback device 110 to perform vibration feedback, the vibration feedback device 110 generates edge vibration, so that the flexible connecting arm 211 elastically deforms and is transmitted to the whole area of the touch pad via the flexible connecting arm 211, thereby improving the consistency of vibration feedback in the area of the touch pad, further facilitating the improvement of the vibration feedback effect and improving the user experience. After the vibration is cancelled, the flexible connecting arm 211 is elastically deformed and restored to the original state without force.

In this embodiment, an included angle is formed between the long side direction of the flexible connecting arm 211 and the vibration feedback direction of the vibration feedback device 110, and the included angle is greater than zero and less than or equal to 90 degrees, so that the flexible connecting arm 211 deforms along the component force of the vibration direction, thereby driving the touch pad to perform vibration feedback integrally.

When the included angle of the long side direction of the flexible connecting arm 211 and the vibration feedback direction of the vibration feedback device 110 is 90 degrees, the flexible connecting arm 211 can generate elastic deformation along the vibration feedback direction of the vibration feedback device 110 under the action of the vibration force, so that the whole vibration of the touch pad is driven, the fluctuation range of the vibration feedback acting force in the touch pad area is reduced, and the consistency of the vibration feedback in the touch pad area is further improved.

Referring to fig. 2, the vibration feedback direction of the vibration feedback device 110 is parallel to the long side direction of the touch pad, i.e. the vibration feedback direction of the vibration feedback device 110 is parallel to the horizontal X-axis direction, for example, the vibration feedback device 110 may be an X-axis linear motor. The flexible connecting arm 211 is an elastic sheet structure parallel to the surface of the printed circuit board 100, and the long side direction of the flexible connecting arm 211 is parallel to the short side direction of the touch pad, so that the flexible connecting arm 211 can deform in a plane parallel to the surface of the printed circuit board 100.
