Description
Technical field
Patent of the present invention relates to a kind of vehicle rear, particularly the telescopic rear of a kind of fork-shaped.
Background technology
At present, both at home and abroad about the research of heavy-duty vehicle rear, mainly based on Purely mechanical rear, because the rear protecting distance ground of heavy-duty vehicle is higher, when the vehicle of the type such as car or SUV and heavy goods vehicles knock into the back, easily cause the vehicle such as car or SUV " to pierce " heavy goods vehicles rear overhang part, cause great injures and deaths.At present with the heavy-duty vehicle of adjustable rear, though its rear reduces the ground Clearance, because device is adjustable, create again the problem that intensity is lower.
Adopt electromechanical integration technology both can ensure collision time front vehicle safety, the crossing ability of vehicle can be improved again, protection vehicle when normally travelling, its rear not easily damages.But its cost of correlative protection mechanism of existing electromechanical integration is higher, weight is comparatively large, also not easily universal and popularization.
Summary of the invention
The object of the invention is the more problem that the heavy goods vehicles rear in order to solve existing Purely mechanical and electromechanical integration in use exists and the telescopic rear of a kind of fork-shaped provided.
The telescopic rear of fork-shaped of the present invention is by air cylinder, support and rear bumper composition, wherein air cylinder is fixed on vehicle frame rear wall, the lower end of air cylinder is connected with drive link, air cylinder drives drive link up-and-down movement, the both sides, lower end of drive link are respectively equipped with the first slide block and the second slide block, two support arms of support are articulated by anchor shaft, anchor shaft is fixed on vehicle frame rear wall, two support arms of support are respectively equipped with the first chute and the second chute, first slide block of drive link lower end is embedded in the first chute, first slide block can slide in the first chute, second slide block of drive link lower end is embedded in the second chute, second slide block can slide in the second chute, two support arm lower ends of support are respectively equipped with the 3rd slide block and Four-slider, the rear side of rear bumper is provided with the 3rd chute and the 4th chute, 3rd slide block of a support support arm lower end is embedded in the 3rd chute, 3rd slide block can slide in the 3rd chute, the Four-slider of another support arm lower end of support is embedded in the 4th chute, Four-slider can slide in the 4th chute.
Support is fork configuration.
Principle of work of the present invention is as described below:
When dilly knocks into the back trend after heavy goods vehicles, in the telescopic rear of fork-shaped, air cylinder drives drive link to decline, drive link is by the slip respectively in the first chute and the second chute of the first slide block of lower end and the second slide block thus drive the 3rd slide block of two support arm lower ends of support and Four-slider to move downward, by the 3rd chute on rear side of rear bumper and the 4th chute, rear bumper is declined while 3rd slide block and Four-slider move downward, thus prevent rear compact car from piercing heavy goods vehicles bottom.
When danger is removed, air cylinder in the telescopic rear of fork-shaped drives drive link to rise, drive link is by the slip respectively in the first chute and the second chute of the first slide block of lower end and the second slide block thus drive the 3rd slide block and Four-slider upward movement of two support arm lower ends of support, make rear bumper increase by the 3rd chute on rear side of rear bumper and the 4th chute while 3rd slide block and Four-slider upward movement, thus improve the crossing ability of heavy goods vehicles.
Beneficial effect of the present invention:
The telescopic rear of fork-shaped of the present invention adopts pneumatic transmission, directly can use heavy goods vehicles self source of the gas, is convenient to install and drive, and sturdy and durable, long service life; Mechanism is simple, easy for installation, and cost is lower, is easy to the marketization; Safe and reliable, air cylinder action is accurate, and precision is high.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5:
The telescopic rear of fork-shaped of the present invention is by air cylinder 1, support 2 and rear bumper 3 form, wherein air cylinder 1 is fixed on vehicle frame rear wall 4, the lower end of air cylinder 1 is connected with drive link 11, air cylinder 1 drives drive link 11 up-and-down movement, the both sides, lower end of drive link 11 are respectively equipped with the first slide block 12 and the second slide block 13, two support arms of support 2 are articulated by anchor shaft 5, anchor shaft 5 is fixed on vehicle frame rear wall 4, two support arms of support 2 are respectively equipped with the first chute 21 and the second chute 22, first slide block 12 of drive link 11 lower end is embedded in the first chute 21, first slide block 12 can slide in the first chute 21, second slide block 13 of drive link 11 lower end is embedded in the second chute 22, second slide block 13 can slide in the second chute 22, two support arm lower ends of support 2 are respectively equipped with the 3rd slide block 23 and Four-slider 24, the rear side of rear bumper 3 is provided with the 3rd chute 33 and the 4th chute 34, 3rd slide block 23 of support 2 one support arm lower ends is embedded in the 3rd chute 33, 3rd slide block 23 can slide in the 3rd chute 33, the Four-slider 24 of another support arm lower end of support 2 is embedded in the 4th chute 34, Four-slider 24 can slide in the 4th chute 34.
