Automobile electric pedal mechanism

Abstract

The invention relates to an automobile electric pedal mechanism which is mainly composed of a motor, a connecting rod mechanism and an anti-backlash spring which are installed in a base, a shell used as a pedal is installed over the base, a support cross beam is installed in the shell, and the lower portion of the support cross beam is connected with a fixed rotating shaft through a connecting piece. The connecting rod mechanism is composed of a transition push rod, a support rod and a rocker; a driving rod of the motor is connected with one end of the transition push rod, the other end of the transition push rod sleeves a fixed rotating shaft, two ends of the fixed rotating shaft are respectively hinged with the support rod and the rocker, one end of the anti-backlash spring is fixed on the base, and the other end of the anti-backlash spring sleeves the fixed rotating shaft. The mechanism is simple in structure, and the transition push rod can absorb part manufacturing and mounting errors to a certain extent; the opening angle can be controlled by the length of the motor screw, and a travel switch is not needed; the connecting rod mechanism decomposes / bears load, and the motor load is small; other locking and bearing structures do not need to be configured, and the cost is low; and the anti-backlash spring can effectively control the fit clearance of the automobile electric pedal mechanism at each working position.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an electric pedal mechanism for automobiles. Background technique [0002] With the popularization of cars, people have higher and higher requirements for the comfort and functionality of the car, so the comfort of man-machine has gradually become an important factor for people to consider when buying a car. In order to improve the comfort of passengers in the rear, the existing high-end models have gradually increased the functional requirements for electric pedal adjustment. [0003] The prior art discloses a pedal device for automobiles having a pedal and a turning mechanism for rotatably adjusting the pedal, the turning mechanism comprising a wrap spring clutch and a lever for unlocking the wrap spring clutch. The drive motor, wherein, when the drive motor is started, the wrap spring clutch is disabled, so that the pedal rotates downward due to its own weight...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned prior art has the following problems: 1. It is necessary to configure a small recliner mechanism, which is limited; 2. It is necessary to increase the travel switch, which increases the cost; 3. It is necessary to configure a wrap spring clutch, which increases the cost and limits the carrying capacity; 4. The motor bears the external load directly, so the carrying capacity is low
