Description

Support assembly of an electric pedal for a vehicle TECHNICAL FIELD

[0001] The present application relates to the technical field of electric pedal for a vehicle, and particularly relates to a support assembly of an electric pedal for a vehicle. BACKGROUND

[0002] There are some vehicles with high chassis distance from the ground, such as pickup trucks, off-road vehicles and the like, and the step height for getting on and off the vehicle is far beyond the comfortable step height of human body. At this time, the installation of an electric pedal on the vehicle can create a height suitable for the user to get on and off the vehicle, and assist the user to get on and off the vehicle smoothly. At present, most electric pedals use four-bar linkage structure, which can only move in Y direction and Z direction, and cannot move in X direction. Due to the modeling of the side skirt of some vehicle models, the distance between the four-bar linkage structure electric pedal and the rear door of the vehicle in X direction is far, so that even if the pedal is fully opened, the user can only step on a little bit or cannot step on the pedal when getting on and off the vehicle from the rear door position. The swing arm structure electric pedal can move in X direction, Y direction and Z direction, which can avoid the problem that the user can only step on a little bit or cannot step on the pedal when getting on and off the vehicle from the rear door position after the pedal is fully opened. However, the existing swing arm structure electric pedal must be used with the active swing arm structure and the driven swing arm structure, that is, two sets of swing arm structures are needed to be used at the same time, and a single swing arm structure cannot be used. Due to the poor stability of the single swing arm structure, the pedal is easy to rotate freely, so that there is a safety hazard when the user uses it. At the same time, the production cost of the electric pedal using two sets of swing arm structures is high. For example, the Chinese invention patent with the document number CN 106585499 A, published on April 26, 2017, and the patent name is a kind of automobile swing arm type electric pedal, which discloses a main rocker arm, a secondary rocker arm and a footrest. The main rocker arm includes a main rocker arm support and a main swing support arm, and the secondary rocker arm includes a secondary rocker arm support and a secondary swing support arm. The main rocker arm support and the secondary rocker arm support are both installed on the same side of the vehicle body bottom. The main swing support arm is provided with a first fixed axis and a first movable axis which are parallel to each other, and the secondary swing support arm is provided with a second fixed axis and a second movable axis which are parallel to each other. The distance from the first fixed axis to the first movable axis is equal to the distance from the second fixed axis to the second movable axis. One end of the main swing support arm is rotatably connected with the main rocker arm support and can rotate relative to the main rocker arm support around the first fixed axis, and the other end of the main swing support arm is rotatably connected with the footrest and can rotate relative to the footrest around the first movable axis. One end of the secondary swing support arm is rotatably connected with the secondary rocker arm support and can rotate relative to the secondary rocker arm support around the second fixed axis, and the other end of the secondary swing support arm is rotatably connected with the footrest and can rotate relative to the footrest around the second movable axis. The main rocker arm support is provided with a driving motor for driving the main swing support arm to rotate around the first fixed axis. The technical solution adopted by the electric pedal is to use two sets of swing arm structures at the same time. Therefore, it is necessary to provide a solution to solve the problem that the existing swing arm structure electric pedal must use two sets of swing arm structures at the same time. SUMMARY
