Embodiment approach
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0035] see figure 2 , a pressure sensing device provided by the first embodiment of the present invention, comprising:
[0036] first panel 10;
[0037] a second panel 20 arranged at a distance from the first panel 10, and an accommodation space 50 is formed between the first panel 10 and the second panel 20;
[0038] The pressure sensing component 30 accommodated in the accommodation space 50, the pressure sensing component 30 includes an elastic bearing plate 31 and a pressure sensor 32, the elastic bearing plate 31 and the pressure sensor 32 are opposed along the thickness direction of the fi...

The pressure applied on the surface of the first panel (10) is measured by a simply supported beam pressure sensing component (30), and the pressure sensing component (30) abuts against the second fulcrum (33) through the first fulcrum (34) Between the first panel (10) and the second panel (20). When the user applies pressure on the pressing area (11), the pressure is transmitted through the first panel (10) to the fulcrum abutting against the first panel (10), and then the pressure is transmitted to the elastic bearing plate (31). At the same time, since the second panel (20) is fixed on the first panel (10), the reaction force of the force exerted by the user acts on the fulcrum abutting against the second panel (20), and the pressure is all concentrated on the elastic bearing plate (31) . The elastic bearing plate (31) deforms under pressure. The pressure sensor (32) detects the deformation of the elastic bearing plate (31), and the pressure sensor (32) outputs a pressure signal to the pressure sensing detection circuit, which is analyzed and processed and then output to the processor for action.
Description
technical field [0001] The invention belongs to the field of pressure sensing, in particular to a pressure sensing device and electronic equipment with the pressure sensing device. Background technique [0002] In the prior art, most of the pressure sensing devices are capacitive or inductive pressure sensing devices; they have poor stability under external impact; and the structural assembly accuracy is high, and a high relative flatness needs to be maintained. At the same time, electronic devices in the prior art, such as mobile phones and tablet computers, all use mechanical keys to realize switching on and off of the electronic devices and volume adjustment. see figure 1 , because the mechanical key needs a certain stroke to be effective, so it is necessary to open a mounting hole 2011 for accommodating the mechanical key cap 202 on the first panel 201 . When the user presses the mechanical key cap 202, the mechanical key stroke control sheet 203 is compressed inwardly...
