[0030] In order to make the purpose, content, and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings and examples.

[0032] Wherein, the limit hinge comprises: a fixed part, a movable part and a rotating shaft; the movable part is welded to the pedal frame, and the fixed part is welded to the side beam of the cargo box;

[0033] The unfolding process of the pedal is as follows: after manually turning the limit pin to release the constraint of the pedal, the pedal can be manually rotated around the limit hinge, and the movable part rotates with the pedal. When the pedal is in a horizontal state, the movable part contacts and rests against the bottom of the cargo box, realizing the mechanical limit of the pedal.

[0034] Among them, the boarding platform also includes a step ladder; one end of the step ladder is rotatably connected to the pedal, and the other end is connected to the locking pin on the inner side of the pedal; the unfolding process of the step ladder is: after the locking pin is manually rotated to release the constraint of the step ladder, the step ladder is manually rotated around the pedal until the step ladder contacts the ground. At this time, people can climb the step ladder to get on the vehicle or cargo box and stand on the horizontal pedal.

[0035] The step ladder is folded by performing the reverse operation of the unfolding process of the step ladder; and the step pedal is folded by performing the reverse operation of the unfolding process of the step pedal, thereby folding the boarding platform.

[0036] The folded boarding platform is coordinated with the outer contour of the cargo box, and the steps are hidden inside the cargo box.

[0037] The frame of the pedal and the inner covering plate use a common cargo box railing structure.

[0038] Among them, the plate covering the inner side of the pedal frame is provided with anti-slip measures, such as particles or stripes, etc., which are generally the inherent structural characteristics of the plate.

[0039] The length of the step ladder is designed according to the height of the roof from the ground, and the step ladder structure can be various and is not restricted by the present invention.

[0040] The boarding platform is manually unfolded and folded by a person standing on the ground; the unfolded boarding platform allows people to board the vehicle and expands the standing or operating space for people after boarding; the folded boarding platform is coordinated with the outer contour of the cargo box, and the steps are hidden inside the cargo box.

[0041] Among them, the pedal in the boarding platform has a vertical state and a horizontal state; in the vertical state, the pedal is fixed to the cargo box by a limit pin and a limit hinge; after the limit pin constraint is released, the pedal rotates and flips to the outside of the cargo box until it reaches a horizontal state; in the horizontal state, the person stands on the pedal, and the pedal is only constrained to the cargo box by the limit hinge.

[0042] The limit hinge is used to constrain the pedal from rotating and is also used for mechanically limiting the pedal in a horizontal state.

[0043] Example 1

[0044] like Figure 1 As shown, the present invention provides a boarding platform, comprising a pedal (1), a limit pin (2) and a limit hinge (3). The boarding platform is installed on the side of the cargo box, and the outer contour of the boarding platform (such as structural style and size) is basically coordinated with other structures on the cargo box and does not exceed the width of the cargo box. At this time, the boarding platform is in a folded state.

[0045] like Figure 1a As shown, in the folded state, the pin shaft of the limit pin (2) is inserted into other adjacent structures on the cargo box to keep the pedal (1) in a vertical state, ensuring that the pedal (1) does not flip over by itself.

[0046] like Figure 1bAs shown, the limit hinge (3) is composed of a fixed part (3-1), a movable part (3-2) and a rotating shaft (3-3), etc. The fixed part (3-1) is fixedly connected to the cargo box, and the movable part (3-2) is fixedly connected to the pedal (1). In the folded state, the movable part (3-2) of the limit hinge (3) does not contact the bottom of the cargo box.

[0047] like Figure 1c As shown, in the folded state, the step ladder (4) is inside the cargo box and is fixed by a lock pin (5). The lock pin (5) has the same structure as the limit pin (2).

[0048] like Figure 2 As shown, the boarding platform is in the unfolded state. After the locking pin (5) is released, the step ladder (4) rotates around the pedal (1) until it touches the ground. In the unfolded state, a person can board the vehicle (or cargo box) through the step ladder (4) and stand on the pedal (1).

[0049] like Figure 2a As shown, before unfolding, the limit pin (2) is manually rotated 180° to separate its pin shaft from other adjacent structures on the cargo box, thereby unlocking the pedal (1).

[0050] like Figure 2b As shown, the pedal (1) is manually turned over and rotated around the limit hinge (3) until the pedal (1) is horizontal. At this time, the movable part (3-2) of the limit hinge (3) contacts and abuts against the bottom of the cargo box, thereby achieving mechanical limit of the pedal (1) and keeping the pedal (1) in a horizontal state.

[0051] like Figure 2c As shown, the locking pin (5) is manually rotated 180° to disengage the pin shaft from the step ladder (4) to unlock the step ladder (1). At this point, the step ladder (4) is manually turned over and rotated until the root of the step ladder (4) touches the ground, and the boarding platform is unfolded.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
