Abstract
Disclosed is a ladder assembly and a vehicle with a ladder assembly. In some aspects, the ladder assembly includes a mounting frame, a first ladder frame, and a second ladder frame, wherein the first ladder frame is pivotally connected with the mounting frame so that the first ladder frame swings between a stowed position and a deployed position relative to the mounting frame, and the second ladder frame is slidably connected with the first ladder frame so that the second ladder frame moves between an extended position and a retracted position relative to the first ladder frame.
Claims19
A ladder assembly, comprising:
- a mounting frame;
- a first ladder frame pivotally connected with the mounting frame, so that the first ladder frame is configured to swing between a stowed position and a deployed position relative to the mounting frame;
- and
- a second ladder frame slidably connected with the first ladder frame, so that the second ladder frame is configured to move between an extended position and a retracted position relative to the first ladder frame.

A ladder assembly, comprising:
- a mounting frame;
- a first ladder frame pivotally connected with the mounting frame;
- a second ladder frame extendably and retractably connected with the first ladder frame;
- a connecting rod having a first connecting-rod end pivotally connected with the mounting frame, and a second connecting-rod end pivotally connected with the first ladder frame;
- and
- a locking part for locking the first ladder frame to prevent the first ladder frame from swinging relative to the mounting frame or for releasing the first ladder frame to allow the first ladder frame to swing relative to the mounting frame,
- wherein the ladder assembly is configured to move between the following states:
- a stowed state, in which the first ladder frame swings into the mounting frame and is arranged side by side with the mounting frame, and the second ladder frame is retracted relative to the first ladder frame;
- a deployed state, in which the first ladder frame swings out from the mounting frame and forms a predetermined included angle with the mounting frame;
- and
- an extended state, in which the first ladder frame swings out from the mounting frame to form a predetermined included angle with the mounting frame, and the second ladder frame extends out relative to the first ladder frame.

A ladder assembly, comprising:
- a mounting frame comprising side frame beams and a cross frame beam, wherein the side frame beams are arranged at intervals in parallel with each other, the cross frame beam is connected between the side frame beams, each side frame beam has a guide groove extending along a longitudinal direction of the side frame beam, and an inner side surface of each side frame beam has an accommodating groove;
- a first ladder frame comprising first ladder side beams and a first ladder cross beam, wherein the first ladder side beams are arranged at intervals in parallel with each other, the first ladder cross beam is connected between the first ladder side beams;
- and each first ladder side beam has a first sliding groove extending along a longitudinal direction of the first ladder side beam;
- an upper end of each first ladder side beam is pivotally connected with a corresponding side frame beam, the first ladder frame is configured to swing into the mounting frame so that each first ladder side beam is arranged side by side with the corresponding side frame beam and located on an inner side of the corresponding side frame beam, and the first ladder frame is configured to swing out from the mounting frame so that each first ladder side beam intersects with the corresponding side frame beam;
- a second ladder frame comprising second ladder side beams and a second ladder cross beam, wherein each second ladder side beam comprises an upper side beam section and a lower side beam section, a lower end of the upper side beam section is pivotally connected with an upper end of the lower side beam section, the second ladder cross beam is connected between the lower ends of the lower side beam sections, each second ladder side beam is slidably arranged in a corresponding first sliding groove, the second ladder cross beam is configured to be retracted into the corresponding first sliding groove, and the second ladder cross beam is located outside the first sliding groove to abut against a lower end of the first ladder frame, and each second ladder side beam is configured to extend out from the corresponding first sliding groove so that the lower end of the upper side beam section and the lower side beam section are located outside the first sliding groove and the lower side beam section rotates relative to the upper side beam section to extend in a vertical direction;
- a connecting rod having a first connecting-rod end pivotally connected with each side frame beam and configured to slide along the guide groove, and a second connecting-rod end pivotally connected with the first ladder side beam;
- and
- a locking part configured to releasably lock the connecting rod to prevent or allow the first connecting-rod end to slide along the guide groove, so as to prevent or allow the first ladder frame to swing relative to the mounting frame.
