Embodiment 1

[0024] Example 1, such as image 3 , 4 , shown in 5, a kind of adjustable pedal assembly, comprises pedal support 14, and rotating shaft 8 is set on the pedal support 14, and rotating shaft 8 is hingedly provided with the pedal arm of pedal, and return extension spring 15 is also set on the pedal arm; 15 other ends are connected and fixed on the pedal bracket 14. Below the pedal bracket 14 rotating shafts, an arc groove 16 is also arranged, and two bolts (9, 10) that can slide and adjust the stroke of the limit pedal arm are set in the arc groove 16; pedal arm.

[0025] Described pedal arm comprises upper pedal arm 17, middle pedal arm 20, lower pedal arm 22; Described upper pedal arm 17 and middle pedal arm 20 are connected by bolt 19, and the bolt hole 18 on it is groove hole; The middle pedal arm 20 and the lower pedal arm 22 are hinged by bolts 21. In this way, the upper pedal arm and the middle pedal arm can move relatively to realize the change of the length of the p...

Embodiment 2

[0026] Embodiment 2 is an adjustable pedal assembly. In order to ensure a more balanced pedal movement, there are two extension springs 15, which are arranged on both sides of the pedal arm. All the other are with embodiment 1.

Abstract

The invention discloses an adjustable pedal assembly, which comprises a pedal support, wherein the pedal support is provided with a rotating shaft which is hinged with a pedal arm provided with a pedal; the pedal arm is provided with a return tension spring; the other end of the tension spring is connected and fixed on the pedal support; an arc chute is arranged under the rotating shaft of the pedal support; two bolts capable of adjusting the travel of the pedal arm in a sliding way and limiting the travel of the pedal arm are arranged in the arc chute; and the pedal arm is capable of telescopically adjusting the length and the rotating angle of the pedal. A multi-degree-of-freedom combined pedal system using the pedal assembly comprises a gantry frame consisting of horizontal rails, upright posts and a cross beam, wherein adjustable clutch pedal assembly, a braking pedal assembly and an acceleration pedal assembly are sequentially arranged on the cross beam; the horizontal arms, the upright posts and the cross bear are matched by adjustable-position sliding rails and adjustable-position chutes and are fixedly connected by bolts; and the connecting support of the adjustable pedal assembly is matched and connected with the cross beam through a T-shaped plate and a panel. Due to both the adjustable pedal assembly adopting the pedal arm capable of telescopically adjusting the length and rotating angle of the pedal and the adjustable support, the system is a practical tool for verifying man-machine subjective evaluation.

Description

technical field [0001] The invention relates to a verification tool for man-machine subjective evaluation, in particular to an adjustable pedal assembly and a multi-degree-of-freedom combined pedal system using the assembly. It is a reusable physical evaluation and verification tool for combined pedal systems that can verify multiple schemes. Background technique [0002] With the development of the global automobile market and increasingly fierce competition, vehicle ergonomics performance is becoming an important factor affecting user purchase behavior and user satisfaction, and human-machine comfort has attracted more and more attention from major automobile manufacturers. At present, when vehicles are developing combination pedals, some empirical data values ​​or data obtained by measuring the combination pedals of related models are used for ergonomic layout. This traditional method, which mainly relies on experience and reverse arrangement, cannot be evaluated subject...
