[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 small. When the height exceeds the threshold, passengers are very likely to get their feet pinched or trip over 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 kind of automobile self-locking torsion type double-layer electric welcome pedal to solve the problem raised. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a self-locking torsion-type double-layer electric welcome pedal for an automobile.

[0007] A self-locking torsion-type double-layer electric welcome pedal for automobile comprises a fixed pedal, wherein a motor and two fixing frames are fixedly installed in the fixed pedal, an output shaft is fixedly installed at the output end of the motor, two worms are arranged on the output shaft, the two worms respectively penetrate the two fixing frames, a worm wheel is rotatably installed on the fixing frame, an angular coupling is fixedly installed on the worm wheel, 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 fixing seat, the fixing seat is fixedly connected to the fixed pedal, a swing arm is also fixedly provided on the rotating shaft 2, a moving pedal is provided at the bottom of the two swing arms, two mounting bases are fixedly installed on the top of the moving pedal, a rotating shaft 1 is provided at the bottom of the swing arm, the rotating shaft 1 penetrates the mounting base, the moving pedal can be raised and lowered and hidden, and can also be self-locking, and is easy to use.

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

[0009] Preferably, the movable pedal is hollow, and two 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 includes the following beneficial technical effects:

[0012] The starting motor drives the output shaft to rotate, thereby driving the two worms to rotate synchronously. The worm and the worm wheel cooperate to drive the worm wheel 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 moving pedal are rotationally connected, thereby driving the moving pedal to move. Due to the characteristics of the cooperation between the worm and the worm wheel, the self-locking function can be achieved, and the upper surface of the moving 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 moving pedal. After folding, it is stored in the fixed pedal to effectively avoid the moving 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.
