Abstract

A self-adaptive pedal plate is composed of a working rod (1), a pedal plate (2), a U-shaped seat (3), a fixing shaft (4), a washer (5) and a cotter pin (6). The working rod (1) is connected with the pedal plate (2) by the U-shaped seat (3). One end of the working rod (1) is semicircular shape and a mounting hole is provided in the center of a circle. The U-shaped seat (3) is fixed on the pedal plate (2). The end of the working rod (1) is arranged in an opening of the U-shaped seat (3) and is fixed by the fixing shaft (4) passing through the installing hole on the U-shaped seat (3) and the installing hole on the working rod (1). The self-adaptive pedal plate can automatically adjust the angle between the pedal plate and the working rod (1) according to the change of a working stroke of the pedal plate so as to ensure that the contact surface between a sole and the pedal plate keeps steady and reduce the requirements for the experience and capacity of an operator.

Description

Adaptive pedal

Technical field

The invention relates to a foot pedal for vehicle control, and other foot controllers, belonging to the foot pedal application technology.

Background technique

Currently used pedals, especially the hanging brake pedals and clutch pedals, most of the pedals and the working rod are connected by means of direct fixed connection, that is, the pedals and work The angle between the rods cannot be changed. Therefore, during work, as the position of the foot pedal changes, the angle between the foot pedal and the sole of the operator is also constantly changing. If the operator's sole does not adjust the angle, the contact area with the foot pedal is reduced. It also produces slippage, which can easily lead to operational errors. If you want to keep the contact surface between the pedal and the sole stable, you must do so by adjusting the angle of the sole with the angle of the foot pedal. Therefore, during the operation of the pedal, the contact surface between the pedal and the sole is kept stable, which requires the operator to have a good ability to feel the change, the ability to judge the reaction, and the ability to cooperate with the limb.

Therefore, it is necessary to find a new type of foot pedal, which can automatically adjust the angle between the foot pedal and the working rod according to the change of the working stroke of the foot pedal, so that the contact surface between the sole and the foot pedal is stable and lowered. Requirements for operator experience and ability.

Summary of the invention

The object of the present invention is to provide an adaptive foot pedal capable of automatically adjusting the angle between the foot pedal and the working rod according to the change of the working stroke of the foot pedal, so as to stabilize the contact surface between the sole and the foot pedal. Reduce the requirements for operator experience and ability.

The technical solution of the present invention is: an adaptive foot pedal composed of a working rod 1, a foot pedal 2, a U-shaped seat 3, a fixed shaft 4, a washer 5, a split pin 6, a working rod 1 and a foot board 2 Connected by U-shaped seat 3.

The end of the working rod 1 is semi-circular and has a mounting hole at the center of the circle.

The U-shaped seat 3 is fixed to the footboard 2.

The end of the working rod 1 is disposed in the opening of the U-shaped seat 3, and is fixed by the fixing shaft 4 through the mounting hole on the U-shaped seat 3 and the mounting hole on the working rod 1.

The beneficial effects of the invention are:

1, According to the working state, the angle between the foot pedal and the working rod can be automatically adjusted to maintain the stability of the contact surface between the sole and the foot pedal, thereby reducing the operator's experience and ability requirements.

2. Prevent slippage and reduce safety hazards.

The invention will now be further described with reference to the drawings and embodiments.

detailed description

As shown in FIG. 1, the adaptive foot pedal of the present invention is composed of a working rod 1, a foot pedal 2, a U-shaped seat 3, a fixed shaft 4, a washer 5, and a split pin 6. The end of the working rod 1 is a semicircle. The shape is provided with a mounting hole at the center of the center, and the U-shaped seat 3 is fixed to the footboard 2.

As shown in FIG. 2 and FIG. 3, the working rod 1 and the foot board 2 are connected by a U-shaped seat 3, and the end of the working rod 1 is disposed in the opening of the U-shaped seat 3, and the fixing shaft 4 passes through the U-shaped seat 3. The mounting hole and the mounting hole on the working rod 1 are then fitted with the washer 5 and finally fixed by the split pin 6.

As shown in FIG. 4, the ordinary foot pedal, since the connection between the working rod 1 and the foot board 2 is fixed, the angle between the foot board 2 and the working rod 1 does not change during operation. If the sole of the foot is kept parallel with the stepping down, the contact surface between the sole of the foot and the footboard 2 changes, the contact area becomes small, and it is easy to slide, which poses a safety hazard.

As shown in FIG. 5, in the adaptive foot pedal of the present invention, since the working rod 1 and the foot board 2 are connected through the U-shaped seat 3, the angle between the foot board 2 and the working rod 1 during operation is Will automatically adjust the change as the position of the work bar 1 changes. When the operator steps on, the working rod 1 will move forward, and the foot pedal 2 will rotate with the fixed shaft 4 as the axis, automatically adjusting the angle between the foot pedal 2 and the working rod 1, so that the sole and the foot The contact surface between the pedals 2 remains stable and does not slip, reducing the operator's experience and ability.

The above-mentioned embodiments are merely illustrative of the use of the present invention, and are not intended to limit the present invention. Those skilled in the art can make various changes or substitutions within the scope of the present invention. The scope of protection of the invention.
