Description

Pedal type brake switch device

Technical Field

The invention relates to the technical field, in particular to a pedal type brake switch device.

Background

In the prior art, devices such as a pedal brake switch and the like can convert a treading force in a roughly vertical direction into a pulling force or a pushing force in a horizontal direction so as to meet the requirements of braking or switching.

However, the existing large class of pedal brake switch devices have some defects, which increase the difficulty of use. Because the working principle of the existing pedal brake switch device is as follows: when the pedal plate is stressed, the pedal plate starts to move from a starting point, and when the pedal plate moves to a certain set working point in the midway, the connecting structure is started and locked; when the foot pedal is depressed again, the unlocking is released. However, since the working point is not the end point of the movement of the foot pedal, but between the starting point and the end point, in practical use, the operator must slowly depress the foot pedal and carefully sense the movement of the foot pedal, and at the same time, precisely control the treading force, and sense that the foot pedal reaches the designated working point before being locked or released. If an operator makes a mistake during operation, the connecting structure of the pedal plate exceeds a specified working position point, the connecting structure is reset, and the locking cannot be realized.

It can be seen that the pedal brake switch device has high requirements on the use of an operator, needs special training or instruction before use, and needs a long time to feel the correct position each time the pedal brake switch device is operated, which is not beneficial to locking a brake, unlocking or switching in time, and is easy to delay the best time of operation.
