Description
Technical field
The invention belongs to auto-safety mechanism field, more particularly to a kind of hydraulic cushion bumper.
Background technology
Bumper is to absorb and slow down foreign impacts power, the safety device of protection vehicle body front and rear part.Many years before
Automobile front/rear collision bumper is into channel-section steel with steel plate punched, rivets or welds together with longitudinal beam, with vehicle body have one section compared with
Big gap, it appears that very unsightly.As the development and engineering plastics of auto industry are in the extensive application of auto industry, vapour
Car bumper has also moved towards the road of innovation as a kind of important safety device.The car front/rear collision bumper of today is except keeping
Outside original defencive function, also to pursue with car body moulding harmony with uniformly, the lightweight of pursuit itself.The front and rear guarantor of car
Dangerous thick stick is all that people are referred to as plastic bumper made of plastics.The plastic bumper of general automobile be by outside plate, padded coaming and
Crossbeam three parts form.Wherein outside plate and padded coaming is made of plastic, and crossbeam is stamped to form U-lag with flat cold-rolled sheet；Outside plate
Crossbeam is attached to padded coaming.
When running into collision, all active forces can all act on the contact surface of expansion bumper at present, produce huge
Pressure, the cushioning effect for depending merely on a bumper is also not enough to be formed to be effectively protected, and bumper is mainly rigidly connected
On vehicle frame, power during expansion is largely transferred on vehicle body, and so as to damage vehicle, human body is damaged.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides a kind of hydraulic cushion bumper, separator tube, structure have been added
Simple possible, there is good energy-absorbing function, while impact can be transmitted along separator tube and hydraulic oil to vehicle body both sides, play
Cushioning effect, reduce the injury to vehicle and people.
The technical scheme is that：A kind of hydraulic cushion bumper, it is installed on body forward structure or the bumper frame at rear portion
On, it is characterised in that the bumper includes thick stick body and several separator tubes, the separator tube be located at thick stick body and bumper frame it
Between, the separator tube length direction extends to vehicle body both sides, and the separator tube is fixed on thick stick body, and the separator tube is hollow form
And it is closed at both ends, two relative pistons are provided with the separator tube, piston perisporium is fitted close with buffering inside pipe wall, two work
Plug forms the chamber of closing in separator tube, is full of hydraulic oil in the chamber of closing, between the end wall of the piston and separator tube
Provided with spring, the spring is fixed on piston, and the piston is provided with sealing ring, the sealing in the side contacted with hydraulic oil
Circle is integrally formed with piston.
Further, the separator tube is fixed by connection sheet and thick stick body, and the connection sheet is integrally formed with separator tube, institute
Connection sheet is stated to be welded to connect with thick stick body.
Further, the cross section of the connection sheet is arc.
Further, the piston is flat-head piston.
Further, the separator tube both ends are closed by plug.
Further, the separator tube at least two.
Further, the separator tube cross section is shaped as circular or ellipse.
Further, the hydraulic oil presses oil for biodegradable fluid.
The present invention working method be：
When car is knocked, separator tube is deformed by the effect of power, no matter how small deformation, between two pistons
Chamber volume can reduce, and hydraulic oil rushes at separator tube both ends, drive the impact of forward direction to be transmitted to vehicle body both sides, will just
It is changed into the power parallel to headstock to the direction of power, alleviates the effect of impact to occupant, if impact is larger, deforms
Larger, spring can touch plug, and spring is compressed, and can also play certain cushioning effect, if impact is very big, spring meeting
Plug is extruded separator tube, and the hydraulic oil in chamber presses oil for biodegradable fluid, its environmental sound.
The beneficial effects of the present invention are：
The bumper of the present invention has added separator tube, on the one hand separator tube plays a part of reinforcement, on the other hand ought hit
When hitting bumper, impact can be transmitted along separator tube and hydraulic oil to vehicle body both sides, can be effectively reduced shock to people
Power caused by body.
