Automobile hydraulic tailgate reinforcement structure
Technical field
The utility model relates to jump area bevelled actuating unit under the automobile hydraulic tailgate, belongs to automobile technical field.
Background technology
Move down the automobile hydraulic tailgate in order to allow goods more easily move on on the automobile hydraulic tailgate or with goods.The plate point of jump area rear plate should tilt earthward under the automobile hydraulic tailgate.Dull and stereotyped to tilt in order making behind the jump area under the existing automobile hydraulic tailgate, generally pressurizing cylinder to be set and to improve the power of elevating ram for the method for elevating ram pressure boost by increase.This reinforcement structure of existing automobile hydraulic tailgate, needing increases pressurizing cylinder, and it is big to take up room, and increases equipment investment.
Summary of the invention
The objective of the invention is to provide a kind of compact conformation, and the use operation that reduces cost of investment is convenient, the automobile hydraulic tailgate reinforcement structure of stable and reliable operation.
The object of the present invention is achieved like this, automobile hydraulic tailgate reinforcement structure, comprise elevating ram and flat board, it is characterized in that being provided with swing arm, crossbeam and swinging mounting, swinging mounting is connected by bearing pin with crossbeam, swing arm and elevating ram respectively, the back of swinging mounting abuts in crossbeam, and an end of swing arm connects dull and stereotyped.
Drive swinging mounting around moving in a circle with crossbeam bonded assembly bearing pin axle center by elevating ram, this circular movement drives swing arm and does straight-line motion, thereby allows the dull and stereotyped inclination that realizes angle.When flat board rise, when descending the time since swing arm around moving in a circle with swinging mounting bonded assembly bearing pin, the tangential force of its circular movement moves to the crossbeam direction by swinging mounting.Back and crossbeam owing to swinging mounting sticks together again, so this moment, swinging mounting was not done any motion.When flat board descend fall earthward after, elevating ram continues to shrink, and drive swinging mounting and move in a circle around bearing pin, and the circular movement of swinging mounting can drive swing arm and does straight-line motion.The straight-line motion of swing arm can allow flat board move in a circle around the ground-surface contact point of flat board again.Thereby realize dull and stereotyped inclination.
The present invention is simple and reasonable, manufactures easily, and cost is low, saves investment, reduces to take up room.Use operation convenient, stable and reliable operation has the excellent popularization using value.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: crossbeam 1, swinging mounting 2, elevating ram 3, swing arm 4, dull and stereotyped 5.
The specific embodiment
Relevant position at crossbeam 1 is connected swinging mounting 2 with bearing pin with crossbeam 1, the back of swinging mounting 2 is abutted in crossbeam 1.Swing arm 4 usefulness bearing pins connect flat board 5 and swinging mounting 2.Elevating ram 3 is connected with swinging mounting 2 usefulness bearing pins.Like this, when dull and stereotyped 5 rise, when descending since swing arm 4 move in a circle around bearing pin.The tangential force of its circular movement moves to crossbeam 1 direction by swinging mounting 2.Back owing to swinging mounting 2 sticks together with crossbeam 1 again, so this moment, swinging mounting was not done any motion.After dull and stereotyped 5 declines fell earthward, elevating ram 3 continued to shrink.The contraction of elevating ram can drive swinging mounting and move in a circle around bearing pin, does straight-line motion and the circular movement of swinging mounting can drive swing arm.The straight-line motion of swing arm 4 can allow dull and stereotyped 5 to move in a circle around the ground-surface contact point of flat board again.Thereby realize dull and stereotyped inclination.
