Description
One, technical field
The present invention relates to automobile mechanical equipment, be specifically related to compact car tailgate carrying platform control setup.
Two, background technology
The city goods transport is owing to be subjected to road limits, small transporting vehicle such as small-sized barreled cram packer have its market demand, and be easy to operate for cargo handing, needs compact car is reequiped, a small-sized tailgate in light weight, that oad is little is installed during repacking, is convenient to the loading and unloading of goods such as barreled rubbish.Existing compact car tailgate carrying platform control mechanism is when control tailgate lifting and rotary movement, usually adopt following dual mode: a kind of is five cylinder arrangements, it is by the lifting of two hoist cylinder control tailgate carrying platforms, the upset of two oil cylinder control tailgate carrying platforms of closing the door, a pressurized cylinder is coordinated the action of the hoist cylinder and the oil cylinder of closing the door, the shortcoming that this mode exists is not only outside great, square steel bearing roomy and be not suitable for the repacking of dilly, and the hydraulic system structure complexity, need many pipelines; Another kind is two cylinder arrangements, the i.e. lifting of a hoist cylinder control tailgate carrying platform, the upset of the oil cylinder control tailgate carrying platform of closing the door, utilize arbitrary-movement articulator to coordinate the action of the hoist cylinder and the oil cylinder of closing the door, the shortcoming that this mode exists is that the action accuracy of tailgate tilt operation is not high, operate not convenient, also very high to the requirement on machining accuracy of arbitrary-movement articulator.
Three, summary of the invention
The purpose of this utility model is the shortcoming that overcomes existing compact car tailgate carrying platform control setup, provide a kind of simple in structure, from heavy and light, square steel bearing outside wide little, compact car tailgate carrying platform control setup that making is easy, easy and simple to handle.
For realizing above purpose, the utility model compact car tailgate carrying platform control setup technical scheme adopts three cylinder arrangements, comprises square steel bearing, lift arm, one of elevating ram, one of the oil cylinder of closing the door, one of nylon wheel and pressurized cylinder contact to earth; Described square steel bearing is by the crossbeam of bolt on automobile; Described lift arm is an one-piece construction, each side be provided with a support arm, the middle part of lift arm is provided with the elevating ram hinged support, and be connected with described elevating ram by rotating shaft, one end of lift arm is connected with the square steel bearing by rotating shaft, and the other end is connected with the end lower fulcrum of little tailgate carrying platform by rotating shaft; Described elevating ram is arranged on lift arm center line one side, and an end is connected with the square steel bearing by rotating shaft, and the other end is connected with the lift arm middle part by rotating shaft; The described oil cylinder of closing the door is arranged on lift arm center line opposite side, and an end is connected with the square steel bearing by rotating shaft, and the other end is connected with little tailgate carrying platform end lower fulcrum by rotating shaft, and is connected with the described nylon wheel that contacts to earth; Described pressurized cylinder is by being bolted to square steel bearing one side.
The described nylon wheel that contacts to earth is set up in parallel two at little tailgate carrying platform end lower fulcrum by rotating shaft.
The utility model is owing to only adopt three cylinder arrangements, and pressurized cylinder weight obviously is lighter than arbitrary-movement articulator of the prior art, therefore overcome the complex structure that prior art exists, operation inconvenience when the little tailgate carrying platform of Control of Automobile tilts, from shortcoming such as great, a kind of little tailgate carrying platform of miniature car hot-rod control mechanism that is more suitable for is provided, simpler, the easier operation of its structure and hydraulic efficiency pressure system, the deadweight lighter, can realize the inclination of the little tailgate carrying platform of automobile convenient, safely, reliably, automatically, and more help maintenance.
Four, description of drawings
Accompanying drawing is the utility model compact car tailgate carrying platform control setup package assembly scheme drawing.
Five, the specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, the utility model compact car tailgate carrying platform control setup comprises square steel bearing 1, elevating ram 2, lift arm 3, pressurized cylinder 4, the close the door oil cylinder 5 and the nylon wheel 6 that contacts to earth, and described square steel bearing 1 is fixed on the crossbeam of automobile; The cylinder head of elevating ram 2 is connected with square steel bearing 1 by the B axle, and the bar head of elevating ram 2 is connected with the middle part of lift arm 3 by the D axle; One end of lift arm 3 is connected with square steel bearing 1 by the O axle, and the other end of lift arm 3 is connected with the end lower fulcrum of little tailgate carrying platform 7 by the C axle; Pressurized cylinder 4 is fixed on a side of square steel bearing; The end of oil cylinder 5 of closing the door is connected with the square steel bearing by the A axle, and the other end of the oil cylinder 5 of closing the door passes through the E axle and is connected with the end lower fulcrum of little tailgate carrying platform 7; The nylon wheel 6 that contacts to earth is set up in parallel in the both sides of E axle; The square steel bearing is the basis of mechanism, does not participate in transporting merit or rotation.
The realization of lifting/lowering action: when carrying out descending operation, the oil cylinder 5 of closing the door keeps length constant, O, A, 4 of C, E form parallelogram, and little tailgate carrying platform 7 keeps horizontality, and the flexible lift arm 3 that promotes of the piston rod of elevating ram 2 drives the lifting that little tailgate carrying platform 7 keeps level.
The realization of opening-closing door action: when carrying out the switch door operation, elevating ram 2 length remain unchanged, and the piston rod of the oil cylinder 5 of closing the door is flexible to promote little tailgate carrying platform 7 around the rotation of C axle, realizes the opening-closing door action.
The realization of tilting action: the subsequent action when this action belongs to tilting action and belongs to little tailgate carrying platform 7 step-down operations.When carrying out step-down operation, little tailgate carrying platform 7 moves downward the maintenance level under the effect of gravity, and the piston rod of elevating ram 2 shrinks, and oil cylinder 5 length of closing the door are constant.When little tailgate carrying platform 7 drops to the nylon wheel 6 that contacts to earth and touches ground, the piston rod of oil cylinder 5 of closing the door begins to shrink, and the oil return of the oil cylinder 5 of closing the door enters into the loculus of pressurized cylinder 4 and stores, when the plate point of little tailgate carrying platform 7 contacts to earth, motion of mechanism stops, and finishes tilting action automatically.
The upwards realization of rotary movement: the origination action when this action belongs to lift operations on the little tailgate carrying platform.During last lift operations, the piston of pressurized cylinder 4 moves from big chamber toward loculus, and the oil return of the original storage of compressing enters the oil cylinder 5 of closing the door, and the piston rod of the oil cylinder 5 of closing the door stretches out, and promotes little tailgate carrying platform 7 and rotates around the C axle; When the piston of pressurized cylinder 4 moves into place, storage oil original in the loculus all enters the oil cylinder 5 of closing the door, after this piston rod of oil cylinder 5 of closing the door is motionless, and little tailgate carrying platform 7 has also turned to horizontality, finishes the little tailgate carrying platform 7 preoperative upwards rotary movement that rises automatically.
