Abstract
The utility model relates to a folding type step ladder for boarding a vehicle used for getting on or getting off a vehicle body. The folding type step ladder for boarding the vehicle comprises an installation frame, and two sets of four-bar mechanisms are arranged on the installation frame in parallel. The installation frame forms a mutual fixed connecting rod of the two sets of four-bar mechanisms, and front rocking beams, rear rocking beams and lower rocking beams are arranged on two sides of the installation frame in pairs and form the other three pendular parts of the four-bar mechanisms. The upper ends of each front rocking beams and each rear rocking arms are hinged on a front hinge joint and a rear hinge joint of the installation frame. The lower ends of each front rocking beam and each rear rocking beam are hinged on two hinge joints of each lower rocking beam, and a footstep is arranged on the front segments of the front rocking beams. A hinge shaft between the rear rocking beams and the lower rocking beams can limit the swinging of the front rocking beams. A power device capable of pushing the four-bar mechanism to reciprocate is arranged on the installation frame. According to the folding type step ladder for boarding the vehicle, the folding and storing in place of a boarding ladder can be achieved conveniently, people can get on or get off the vehicle conveniently, and the folding type step ladder for boarding the vehicle is simple in structure, small in occupied space, strong in installation generality, and suitable for installation on vehicles of various types.
Description
Technical field
The utility model relates to a kind of collapsible step board ladder for upper and lower vehicle envelope.
Background technology
Boarding ladder is the auxiliary device for vehicle compartment about the personnel, at present, step on the car device what military products, civilian goods product used, especially for the outside vehicle operation step on the car device, what generally all adopt is moving type, drawing and pulling type boarding ladder, but the common defects that the boarding ladder of these forms exists is: volume is larger, collection takes up room large, moves inconvenience, and collection is fixing inconvenient, and limited by state of ground when using, be unfavorable for stepping on car personnel's use.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple to operation, and is safe and reliable, and the folding step board ladder of highly versatile is installed.
In order to solve the problems of the technologies described above, folding step board ladder of the present utility model includes erecting frame, has the two cover four-bar linkages that are arranged side by side on the erecting frame; Described erecting frame consists of the common stationary links of two cover four-bar linkages, and the front roll bar that the erecting frame both sides arrange in pairs, rear fork and draft link consist of other three parts that can swing of four-bar linkage; Front roll bar and rear fork upper end are hinged on two hinge-points of erecting frame front and back; The lower end of front roll bar and rear fork is hinged on respectively on two hinge-points of draft link, and the leading portion of draft link is provided with pedal; Jointed shaft between described rear fork and the draft link can carry out spacing to the swing of front roll bar; Be equipped with on the described erecting frame and can promote the reciprocating engine installation of four-bar linkage.
Described power engine installation drives four-bar linkage by driving jointed shaft.
Described draft link is comprised of the front curved segment with crooked angle and rear curved segment, and curved segment was in horizontal surface before the setting of described angle made when curved segment is in same straight line behind rear fork and the draft link; Described pedal is arranged on the front curved segment.
The utility model can be installed on the car chassis bottom, can realize conveniently that by the four-bar linkage that arranges on the mounting bracket expansion of boarding ladder and collection put in place, make things convenient for personnel to get on or off the bus, it is simple in structure, space hold is little, highly versatile is installed, is fit to all types of automobiles and installs.
Description of drawings
Fig. 1 is the deployed condition left view of the utility model folding step board ladder;
Fig. 2 is the collecting state left view of the utility model folding step board ladder;
Fig. 3 is the birds-eye view of the utility model folding step board ladder.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, folding step board ladder of the present utility model is described in further detail.
As shown in the figure, this collapsible step board ladder comprises erecting frame 1, has the two cover four-bar linkages that are arranged side by side on the erecting frame 1; Erecting frame 1 consists of the common stationary links of two cover four-bar linkages, and the front roll bar 3 that the erecting frame both sides arrange in pairs, rear fork 4 and draft link 5 consist of other three parts that can swing of four-bar linkages; Front roll bar 3 and rear fork 4 upper ends are hinged on two hinge-points of erecting frame 1 front and back; The lower end of front roll bar 3 and rear fork 4 is hinged on respectively on two hinge-points of draft link 5, and the leading portion of draft link 5 is provided with pedal 6; Jointed shaft 7 between described rear fork and the draft link can carry out spacing to the swing of front roll bar; Be equipped with on the described erecting frame and can promote the reciprocating engine installation 2 of four-bar linkage.Engine installation adopts motor-driven cylinder, and motor adopts direct current 24V Power supply.The power engine installation drives four-bar linkage by driving jointed shaft 7.
Draft link is comprised of the front curved segment 9 with certain crooked angle and rear curved segment 10, and curved segment was in horizontal surface before the setting of described angle made when curved segment is in same straight line behind rear fork 4 and the draft link; Pedal 6 is arranged on the front curved segment 9.
During use, such as Fig. 1, Fig. 2, shown in Figure 3, erecting frame 1 is as the support section of four-bar linkage, doublely simultaneously does the device that attic ladder is connected with car chassis, by connection bracket 7 power output is passed to four-bar linkage by engine installation 2, realize self folding storage and expansion; Pedal 6 scrunches platform as the personnel under the terraced body deployed condition, connects as one with four-bar linkage, launches together and collects in company with four-bar linkage; Under the attic ladder deployed condition, during pushes pedals, four-bar linkage is by self structure realizable force balance, and Poewr transmission mechanism 3 does not bear any curved power and torsion, and reliability of service improves greatly.
