1. A pressure touch pad, comprising a printed circuit board, a pressure sensor, a pressure sensor bracket, and a touch controller; wherein
the printed circuit board is stacked along a first direction on the pressure sensor bracket, a touch electrode layer is provided on one side of the printed circuit board away from the pressure sensor bracket, and the touch electrode layer is configured to, when a finger touches or presses the pressure touch pad, sense a touch position of the finger and output a corresponding touch sensing signal, wherein the first direction is a direction perpendicular to a plane of the pressure touch pad;
the pressure sensor is arranged between the printed circuit board and the pressure sensor bracket, and is configured to, when the finger presses the pressure touch pad, deform and output a corresponding pressure sensing signal;
the touch controller is arranged on one side of the printed circuit board facing the pressure sensor bracket, the touch controller is electrically connected to the touch sensor and the pressure sensor respectively, and the touch controller is configured to receive the touch sensing signal and the pressure sensing signal, and determine the touch position of the finger on the touch pad and a magnitude of a pressure applied by the finger; and
the pressure sensor bracket is configured to bear the printed circuit board and the pressure sensor, and fixedly connect the pressure touch pad to an outer case; wherein the pressure sensor bracket comprises a reinforced region, a non-reinforced region, and a flexible arm, the reinforced region is fixedly connected to the printed circuit board, the non-reinforced region is configured to be fixedly connected to the outer case, the flexible arm is connected to the reinforced region and the non-reinforced region; the non-reinforced region is provided with a plurality of cantilever beams, the pressure sensor is provided on one side of the cantilever beams facing the printed circuit board, and the cantilever beam is connected to the printed circuit board through an elastic gasket.
