AI Technical Summary
When cleaning vehicles, the existing folding ladders have a symmetrical arrangement of the front and rear legs, which prevents the steps from getting close enough to the vehicle, increasing the difficulty of operation and safety hazards, and affecting cleaning efficiency and operational safety.
Design a folding ladder for car washing, wherein the angle formed between the ladder frame and the ground is smaller than the angle formed between the support frame and the ground, and a rear stabilizing foot and a front stabilizing foot are added to increase the support area, the step is abutted against the limit crossbar, and reinforced components and protective sleeves are used to improve stability and safety.
It allows operators to get closer to the vehicle body, reducing the difficulty of operation, improving cleaning efficiency and operational safety. Its structure is simple and reasonable, and it is convenient and quick to use.

Abstract
Claims
1. A folding ladder for car washing, characterized in that: Includes ladder frame, support frame, treads and connecting rods; The top of the support frame is hinged to the upper part of the ladder frame, and the support frame swings relative to the ladder frame about the hinge point as an axis. The ladder has multiple pedals, which are spaced apart and installed inside the ladder frame along its extension direction. The front ends of each pedal are hinged to the ladder frame, and the pedals swing relative to the ladder frame about the hinge points. The rear ends of each pedal are hinged to the connecting rod, and the pedals swing relative to the connecting rod about the hinge points. The ladder frame and the connecting rod are parallel to each other. A limit bar is connected to the upper interior of the support frame; When the car wash folding ladder is in the unfolded state, the uppermost step of the ladder frame abuts against the limiting crossbar, the upper surfaces of the multiple steps are all parallel to the horizontal plane, and in the y-axis direction, the angle formed by the ladder frame and the ground is smaller than the angle formed by the support frame and the ground.
2. A folding ladder for use in washing a vehicle as claimed in claim 1 wherein: It also includes rear stabilizing feet, which are integrally formed at both ends of the bottom of the support frame, and in the z-axis direction, the rear stabilizing feet extend outward relative to the bottom of the support frame; In the y-axis direction, the angle between the support frame and the ground is greater than the angle between the rear stabilizing foot and the ground.
3. A folding ladder for use in washing a vehicle as claimed in claim 2 wherein: It also includes front stabilizing feet, which are integrally formed at both ends of the bottom of the ladder frame, and in the z-axis direction, the front stabilizing feet extend outward relative to the bottom of the ladder frame; In the y-axis direction, the ladder frame and the front stabilizing foot are on the same straight line.
4. The collapsible ladder of claim 1, wherein: A limit block is provided at the bottom rear end of the uppermost step of the ladder along the x-axis direction; When the car wash folding ladder is in the unfolded state, the limiting block abuts against the limiting crossbar.
5. The collapsible ladder of claim 1, wherein: It also includes a reinforcing component connected between the ladder frame and the support frame; The reinforcing assembly includes a first reinforcing rod and a second reinforcing rod, and the outer side of the middle portion of the ladder frame, the first reinforcing rod, the second reinforcing rod, and the outer side of the middle portion of the support frame are sequentially hinged together; When the car wash folding ladder is in the unfolded state, the straight line formed by the first reinforcing rod and the second reinforcing rod extends horizontally.
6. The collapsible ladder of claim 1, wherein: It also includes a limiting rod, one end of which is hinged to the upper part of the connecting rod, and the other end of which is hinged to the middle part of the support frame.
7. A folding ladder for use in washing a vehicle as claimed in claim 6 wherein: The support frame is also connected to a support crossbar inside, and the support crossbar is hinged to the limiting rod.
8. The collapsible ladder of claim 1, wherein: It also includes a protective sleeve, which is fitted over the lower part of the support frame and / or the top of the ladder frame, and the protective sleeve is used to abut against the vehicle to be cleaned.
9. The collapsible ladder of claim 3 wherein: It also includes anti-slip foot covers, which are fitted onto the bottom of the front stabilizing foot and / or the rear stabilizing foot, and the bottom surface of the anti-slip foot covers is rough.
10. The collapsible ladder of claim 1, wherein: The number of pedals is 2 to 4.
