Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a self-locking torsion-type double-layer electric welcome pedal for an automobile. Background Art

[0002] The car welcome pedal is an automotive accessory used to decorate the door sill of a car. Its main function is to facilitate passengers to get on and off the car, prevent collisions and beautify the car body. It has become an indispensable part of the use of modern cars.

[0003] At present, the electric welcome step structure of off-road vehicles on the market is too close to the vehicle body when unfolded, and the height threshold for passengers to get on and off the vehicle is too low. When the height exceeds the threshold, passengers are very likely to get their feet pinched or tripped when getting on and off the vehicle; secondly, the thickness is too large after folding, which is easily scratched and hit, causing structural deformation of the welcome step and making it unable to unfold normally.

[0004] Therefore, those skilled in the art provide a self-locking torsion-type double-layer electric door welcome pedal for an automobile to solve the problem raised. Utility Model Content

[0007] A self-locking torsion-type double-layer electric welcome pedal for automobiles comprises a fixed pedal, wherein a motor and two fixing frames are fixedly installed in the fixed pedal, an output shaft is fixedly installed on the output end of the motor, two worms are provided on the output shaft, and the two worms respectively pass through the two fixing frames, a worm gear is rotatably installed on the fixing frame, an angular coupling is fixedly installed on the worm gear, a rotating shaft 2 is fixedly installed on the other end of the angular coupling, a movable sleeve on the rotating shaft 2 is provided with a fixed seat, the fixed seat is fixedly connected to the fixed pedal, a swing arm is also fixedly provided on the rotating shaft 2, a movable pedal is provided at the bottom of the two swing arms, and two mounting bases are fixedly installed on the top of the movable pedal, a rotating shaft 1 is provided at the bottom of the swing arm, and the rotating shaft 1 passes through the mounting base, so that the movable pedal can be raised and lowered and hidden, and can also be self-locked, and is easy to use.

[0008] Preferably, both ends of the fixed pedal are plugged with dust covers 1, which facilitates installation and prevents dust from entering from both ends of the fixed pedal.

[0009] Preferably, the movable pedal is hollow, and dust covers are inserted at both ends of the movable pedal to reduce weight. The movable pedal can be made by bending a plate to prevent bumps and dust from entering.

[0010] Preferably, a plurality of square holes are evenly arranged on the side of the swing arm to reduce weight.

[0011] In summary, the present invention has the following beneficial technical effects:

[0012] The starting motor drives the output shaft to rotate, thereby driving the two worms to rotate synchronously, and the worm and worm gear cooperate to drive the worm gear to rotate, thereby driving the second rotating shaft to rotate through the angular coupling, which can drive the two swing arms to rotate synchronously. The swing arm and the movable pedal are rotationally connected, thereby driving the movable pedal to move. Due to the characteristics of the cooperation between the worm and the worm gear, the self-locking function can be achieved, and the upper surface of the movable pedal is always parallel to the horizontal plane; the design of the swing arm structure with adjustable length and angle effectively solves the problems of small height difference and small inside and outside parallel difference of the movable pedal. After folding and storing in the fixed pedal, it effectively avoids the movable pedal being scratched and hit by external force, resulting in structural deformation and inability to unfold normally, as well as the problem of affecting the opening and closing of the structure when working in harsh outdoor environments.
