A vibrating positioning tactile floor tile

Abstract

The invention belongs to the field of tactile floor tiles, and in particular relates to a vibration-type positioning tactile floor tile. The lower surface of the spring plate is fixedly connected with a pressure rod, the lower end of the pressure rod is fixedly connected with a pressure plate, a closed bellows is provided directly below the pressure plate, and a plurality of vibration rods are fixedly connected to the lower surface of the spring plate. The ring is fixedly connected with the bottom side wall of the groove through a spring. There is a cavity in the body of the floor tile, and the airtight bellows is connected with the cavity. One end of the channel communicates with the cavity, the other end of the air delivery channel is arranged facing the vibrating ring, and the cavity is sealed and rotatably connected with a rotating cover. The invention feeds back the location information to the blind people through vibration and hearing, which not only lasts longer, but also reduces the difficulty for the blind people to obtain information.

Description

technical field [0001] The invention belongs to the field of tactile floor tiles, in particular to a vibrating positioning tactile floor tile. Background technique [0002] The blind path is a special passage paved with special floor tiles with hard protrusions on the surface. The blind use their sense of touch to feel their position and ensure that they can walk safely on the blind path. [0003] The sense of pressure is to stimulate the senses by squeezing the skin to deform the skin. The sense of vibration is to stimulate the senses through vibration waves of a certain frequency, causing resonance and vibration to stimulate the senses. Due to the fast adaptation of the pressure sense, the duration of the pressure sense is short; and The existing tactile walkways reduce the contact area between the blind person and the ground through protrusions, thereby increasing the pressure, deforming the skin of the soles of the blind person, and feeding back information through the p...

[0003] The sense of pressure is to stimulate the senses by squeezing the skin to deform the skin. The sense of vibration is to stimulate the senses through vibration waves of a certain frequency, causing resonance and vibration to stimulate the senses. Due to the fast adaptation of the pressure sense, the duration of the pressure sense is short; and The existing tactile walkways reduce the contact area between the blind person and the ground through protrusions, thereby increasing the pressure, deforming the skin of the soles of the blind person, and feeding back information through the pressure sensation; however, the conditions for the generation of the pressure sensation are relatively harsh, which is different from the hardness of the sole of the blind person and the blind person's sole hardness. For example, if a blind person wears shoes with hard soles and steps on the floor tiles of the blind passage in a direction parallel to the strip-shaped protrusion, it is difficult to form a pressure feeling, and the actual use effect is poor; in addition, the blind person Walking on the hard bumps of the blind path for a long time will also cause sore muscles on the soles of the feet
