Novel pressure-sensitive pedal controlling device for electric travel tools

Abstract

The invention discloses a novel pressure-sensitive pedal controlling device for electric travel tools. The novel pressure-sensitive pedal controlling device comprises a cover plate and a base plate, the cover plate and the base plate are arranged in a matching mode in space, the edge of the lower surface of the cover plate is connected with the base plate through supporting pillars, and the part between the cover and the base plate is of a distance-telescopic structure; and a raised block is fixedly arranged on the middle position of the lower surface of the cover plate, the raised block is ofa cylinder structure, the middle of the raised block is an inward concave, the inward-concave plane of the middle of the raised block is connected with a water-droplet-shaped spacer through a pressure-proof film, the upper and lower surfaces are of plane film-shaped structures, and the raised block is fixedly connected with the upper part of the water-droplet-shaped spacer. According to the novelpressure-sensitive pedal controlling device for the electric travel tools, the supporting pillars are arranged on the edge of the cover plate, the raised block of a special structure and the water-droplet-shaped spacer are arranged on the middle part of the cover plate, and thus the pressure overload of a high-sensitive nanometer flexible thin-film pressure sensor is effectively prevented; and the novel pressure-sensitive pedal controlling device for the electric travel tools has the characteristics that the structure is simple, the sensitivity is high, and the safety and reliability are achieved.

Description

technical field [0001] The invention relates to a novel pressure-sensitive pedal control device for electric travel tools, in particular to a pressure-sensitive pedal control device, which belongs to the technical field of intelligent control. Background technique [0002] With the increasing development of science and technology, people require travel tools to be more convenient, fast and environmentally friendly. Based on the above reasons, electric travel with pedal intelligent control is gradually becoming a new means of transportation. [0003] At present, there are mainly two ways of pedal control. One is to realize the operation control through the photoelectric switch and the basic components such as gyroscope and acceleration sensor. With the extension of the use time of this control method, the rubber button at the photoelectric switch will be damaged due to fatigue. As a result, its action is insensitive, and its reliability is greatly reduced, thereby affecting t...

[0003] At present, there are mainly two ways of pedal control. One is to realize the operation control through the photoelectric switch and the basic components such as gyroscope and acceleration sensor. With the extension of the use time of this control method, the rubber button at the photoelectric switch will be damaged due to fatigue. As a result, its action is insensitive, and its reliability is greatly reduced, thereby affecting the safety of users, and the entire photoelectric switch needs to take up a large space; the other is to control it by setting a traditional pressure sensor (such as a pressure strain gauge) on the pedal In the operating state, the output signal of this traditional pressure sensor is weak, the anti-interference ability is poor, and it can only measure the average strain within the range of the strain grating, but cannot display the change of the stress gradient in the stress field. In addition, the above two types of devices Due to the lack of overload protection components, the accuracy of the sensor is damaged after overload and pressure, which affects the service life of the sensor
