1. A pressure sensing apparatus comprising:

  • a first panel;

    a second panel spaced apart from the first panel, wherein an accommodation space is formed between the first panel and the second panel;

    a pressure sensing assembly placed in the accommodation space, wherein, the pressure sensing assembly comprises an elastic bearing plate and a pressure sensor, the elastic bearing plate and the first panel abut against each other along a thickness direction of the first panel, the pressure sensing assembly is provided with a first mounting surface and a second mounting surface opposite to each other along the thickness direction of the first panel, the first mounting surface is provided thereon with a first support, the second mounting surface is provided thereon with two second supports arranged to be spaced apart from each other, the first support is disposed in a region between the two second supports;

    the pressure sensing assembly, the first support and the two second supports constitute a simple beam structure, the pressure sensing assembly abuts against and between the first panel and the second panel via the first support and the second supports, and the first panel forms a pressing area in a region between the two second supports;

    a pressure-sensing detection circuit electrically connected with the pressure sensor and configured for receiving pressing signals detected by the pressure sensor; and

    a processor electrically connected with the pressure-sensing detection circuit and configured for outputting an operation signal when receiving the pressure signal from the pressure-sensing detection circuit.
