Description

Measuring tool

Technical Field

The invention belongs to the technical field of distance measurement, and particularly relates to a measuring tool.

Background

The distance between the heel point of the accelerator pedal of an automobile (hereinafter referred to as the accelerator pedal heel point) and the heel point of the brake pedal (hereinafter referred to as the brake pedal heel point) plays an important role in driving comfort. Here, the heel force application point of the accelerator pedal refers to a contact point of the heel and a floor in the vehicle on the assumption that the right foot treads the accelerator pedal at a first calibration angle; similarly, the heel strike point refers to the point of contact of the heel with the floor of the vehicle interior, assuming that the right foot is pedaling the brake pedal at a second nominal angle. Here, the first calibration angle is a comfortable angle or an angle range when the accelerator pedal is stepped on by the simulated right foot. Similarly, the second calibration angle is a comfortable angle or an angle range when the brake pedal is treaded by the simulated right foot.

The distance between the heel force point of the accelerator pedal and the heel force point of the brake pedal is too close, the space is narrow when the right foot is switched back and forth between the accelerator pedal and the brake pedal, the wrong treading is easy to generate, and the driving safety is not facilitated. The distance between the heel acting point of the accelerator pedal and the heel acting point of the brake pedal is too large, the right foot needs to move a larger distance when being switched back and forth between the accelerator pedal and the brake pedal, so that the right foot is easy to be fatigued, and the automobile ergonomic is not met.

Therefore, people hope to obtain an accurate value of the distance between the heel force point of the accelerator pedal and the heel force point of the brake pedal by a simple and effective method before the automobile leaves the factory or during the automobile maintenance. Based on the position of the accelerator pedal and the position of the brake pedal, the distance between the heel force point of the accelerator pedal and the heel force point of the brake pedal is adjusted to a distance which is comfortable for a driver.

However, the conventional distance measuring tool has a simple structure and low flexibility, and cannot be positioned when being directly used for measuring the distance between the heel force point of the accelerator pedal and the heel force point of the brake pedal, so that the accurate measurement of the distance between the heel force point of the accelerator pedal and the heel force point of the brake pedal is difficult to realize.

As shown in fig. 20 and 21, the measuring tool provided in the above embodiment of the present invention has the following operating principle:

for a floor type pedal, the surface of the pedal can be simplified into a plane model, the angles of the first fixture body 3 and the second fixture body 4 relative to the vehicle interior floor 30 do not need to be controlled, namely the first angle protractor 34 and the second angle protractor 44 do not work at this time, the first inner guide rod 321 and the first outer guide rod 322 are attached to the surface of the brake pedal 40 during measurement, the second inner guide rod 421 and the second outer guide rod 422 are attached to the surface of the accelerator pedal 50, and the ball head shell of the first universal ball head connecting rod 31 and the ball head shell of the second universal ball head connecting rod 41 are respectively contacted with the vehicle floor 30. The contact position of the ball shell of the first universal ball head connecting rod 31 and the floor 30 is the heel acting point of the brake pedal, and the contact position of the ball shell of the second universal ball head connecting rod 41 and the floor 30 is the heel acting point of the accelerator pedal. The distance between the heel force application point of the accelerator pedal and the heel force application point of the brake pedal is directly reflected by the main graduated scale 1.

However, for the suspension type pedal, since the surface of the pedal is arc-shaped, the first angle square 34 and the second angle square 44 need to be adjusted to a predetermined angle scale value before the measurement using the measuring tool, and the ball housing of the first universal ball link 31, the ball housing of the second universal ball link 41, the lower end of the first supporting portion 342 of the first angle square 34, and the lower end of the second supporting portion 442 of the second angle square 44 need to be simultaneously contacted with the floor 30.

When measuring the center distance of the suspended pedal, the first and

second protractors

34 and 44 are first adjusted to a desired angle (typically, a certain value of 75 ° to 82 °), and the first and second

protractor locking bolts

10 and 20 are tightened (this step is skipped when measuring the floor-standing pedal). Then, the first clamp 33 is placed on the brake pedal 40, and the second clamp 43 is placed on the accelerator pedal 50, so that the ball shell of the first universal ball link 31, the ball shell of the second universal ball link 41, the lower end of the first support portion 342 of the first protractor 34, and the lower end of the second support portion 442 of the second protractor 44 simultaneously contact the floor 30.
