Embodiment approach

[0069] Further, see Figure 1 to Figure 11 , as a specific embodiment of the push-type tactile sensor provided by the present invention, it also includes: a flexible pressing layer 41 and a raised portion 42 disposed on the flexible pressing layer 41; the raised portion 42 is inserted in the first through hole 221 Inside. In this way, the user can push the protrusion 42 on the flexible pressing layer 41 to move by squeezing the flexible pressing layer 41, and the protrusion 42 inserted in the first through hole 221 can be pushed to cover the first through hole 221 after moving. The elastic membrane 31 is deformed to squeeze the space in the accommodating chamber 23 .

[0070] In one embodiment, the flexible pressing layer 41 is provided with positioning posts, and the substrate 1 is provided with positioning holes. In this way, the flexible pressing layer 41 can be more firmly fixed on the substrate 1 by inserting the positioning post into the positioning hole.

Abstract

The invention relates to the technical field of sensors, and provides a pressing type tactile sensor which comprises a substrate, a light transmission channel arranged on the substrate, a box body with a containing cavity, a sealing cover, a light emitter, a light receiver, an elastic film, a first light-transmitting film and a second light-transmitting film; an opening communicated with the containing cavity is formed in the box body, and the sealing cover covers the opening; the sealing cover is provided with a first through hole communicated with the containing cavity, the box body is provided with a second through hole which is communicated with the containing cavity and located on the light transmission channel, and the box body is provided with a third through hole which is communicated with the containing cavity and located on the light transmission channel; the elastic film covers the first through hole, the first light-transmitting film covers the second through hole, and the second light-transmitting film covers the third through hole; the first light-transmitting film is an integrated piece made of an elastic material. A user can know whether the elastic film on the sealing cover is pressed or not through the change of the preset light beam received by the light receiver.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to a push-type tactile sensor. Background technique [0002] With the continuous improvement of the level of intelligence in various fields, more and more intelligent devices have entered people's work and life, which has led to more frequent interactions between man-machine-environment. In the fields of intelligent prosthetics, virtual reality, remote operation, health monitoring, sorting and grasping, tactile information is one of the main data to reflect and evaluate the interactive behavior of smart devices. In order to improve the sensitivity and accuracy of tactile sensing, so that it has tactile perception performance similar to that of biological skin, in recent years, tactile sensors have been developing towards array and flexibility, so that they can better adapt to external installation and Touch the environment to realize sensitive detection of tactile i...
