It is understood that the connecting unit in the present embodiment may also use three, four, and other numbers of connecting rod assemblies 104 besides two sets of connecting rod assemblies 104.
As shown in fig. 10, a lug 107 protruding outward to connect with the link assembly 104 is provided on the base ladder 103, and as shown in fig. 12, a through hole 1023 for the link assembly 104 to pass through is formed on the lower ladder 102, one end of the link assembly 104 is hinged to the lug 107, and the other end thereof enters the lower ladder 102 through the through hole 1023 and is hinged to the lower ladder 102. In addition, the base ladder 103 is provided with a first limiting portion which can be abutted against the connecting rod assembly 104 to limit the expansion degree of the pull-down ladder 102, and the first limiting portion is specifically a first limiting surface 1071 constructed on the support lug 107.
In order to improve the safety of the vehicle ladder structure 1, as shown in fig. 10, an abutting portion that can abut against the link assembly 104 due to the turning of the link assembly 104 is provided on the lower ladder 102, and specifically, the abutting portion is formed by the inner surface of the through hole 1023. In order to facilitate the locking of the lower ladder 102 and the lower ladder 101, respectively, based on the deployment and storage processes of the vehicle ladder structure 1, the locking unit of the present embodiment includes a first locking portion provided on the base ladder 103 to lock the lower ladder 102, and a second locking portion provided on the link assembly 104 to lock the lower ladder 101.
As shown in fig. 5, 8, 10 and 11, the first locking portion includes a locking member 4 having a locking groove and provided on the base ladder 103, and a locking ring 1022 provided on the lower ladder 102 corresponding to the locking member 4, and a catcher 3 connected to the locking member 4 is provided at the bottom of the lower ladder 102. The locking ring 1022 can be driven into the locking groove by external force to form locking for the pull-down ladder 102, and the locking groove can be opened by operating the handle 3 to make the locking ring 1022 separate from the locking groove, so as to unlock the pull-down ladder 102. In specific implementation, the first locking portion may refer to a back door lock of an existing vehicle, and a detailed structure thereof is not described herein.
Still referring to fig. 10 and 11, the second locking portion is a locking hook 1041 located at one end of each link of the link assembly 104 connected to the lower slide 102, and the locking hook 1041 may form a hook connection with the lower slide 101 to lock the lower slide 101 as the lower slide 102 is received, and the locking hook 1041 may be disengaged from the hook connection with the lower slide 101 to unlock the lower slide 101 when the lower slide 102 is unfolded. With this arrangement, the lower slide 101 can be unlocked when the lower slide 102 is unfolded, so that the lower slide 101 can be conveniently unfolded, and the lower slide 101 can be locked when the lower slide 102 is stored, so that the stability of the storage state of the lower slide 101 can be improved.
As shown in fig. 6 and 7, as a practical embodiment, the lower ladder 101 of the present embodiment is slidably provided on the lower ladder 102. As shown in fig. 12, a sliding groove extending along a length direction of the longitudinal beam of the lower ladder 102 is formed, and the via hole 1023 is disposed corresponding to the sliding groove and is communicated with the sliding groove to pass through the sliding groove and be hooked with the lower ladder 101. As shown in fig. 13, a slider 1011 capable of being fitted into the sliding groove is provided on the lower slide 101 corresponding to the sliding groove, and in order to improve the sliding effect, the sliding groove of the present embodiment is specifically a dovetail groove 1021, and the slider 1011 is a dovetail block disposed along with the dovetail groove 1021.
Specifically, as shown in fig. 14, the steps 1012 provided on the lower slide 101 are fixed by bolts, and at this time, rubber blocks 1013 that respectively abut on the upper and lower ends of the steps 1012 are provided on the lower slide 101 in order to prevent the steps 1012 from turning over, whereby the safety of use of the vehicle ladder structure 1 can be improved. Of course, the pedal 1012 may be fixed by welding instead of being fixed by bolts. It is understood that the steps 1012 of the lower ladder 102 and the base ladder 103 may be fixed by bolts or welding, and rubber blocks 1013 for preventing the steps 1012 from being turned over may be provided when the bolts are used.
In addition, in order to prevent the lower slide 101 from coming off the lower slide 102 and causing a safety risk, the lower slide 102 is provided with a second stopper portion for restricting the sliding displacement of the lower slide 102. The second limiting portion includes an upper limiting block and a lower limiting block respectively configured at the upper and lower ends of the dovetail groove 1021. And through setting up the upper limit piece, can be convenient for push up the upper limit piece through slider 1011 and realize the synchronization action of lower ladder 102 and lower ladder 101 to can be convenient for pull-down 102 accomodate.
When the vehicle ladder structure 1 is unfolded, firstly, a key is used for unlocking and pulling the buckle 3 to unlock the first locking part, and then, the connecting rod assembly 104 is turned downwards by holding the pull-down ladder 102 or the lower slide 101 by hands until the connecting rod assembly 104 is abutted to the support lug 107; at this time, the lower slide 101 is also disengaged from the lower slide 102, and finally, the lower slide 101 is slid down to the lower side of the vehicle body 2 through the slider 1011 until the slider 1011 abuts against the lower stopper, and the extension of the vehicle ladder structure 1 is completed.
