[0043] Example 1
[0044] like Figure 1 As shown, the utility model 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, keeping the pedal (1) in a vertical state and ensuring that the pedal (1) does not turn 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). When 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, people 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, manually rotate the limit pin (2) 180 degrees to separate the pin shaft from other adjacent structures on the cargo box, thereby completing the unlocking of 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 limitation of the pedal (1) and keeping the pedal (1) in a horizontal state.
[0051] like Figure 2c As shown, manually rotate the locking pin (5) 180 ° to disengage the step ladder (4) from the step ladder, thereby completing the unlocking of the step ladder (1). Thus, manually flip the step ladder (4) and rotate it until the step ladder (4) root touches the ground, and the boarding platform is completed and launched.
[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.
