Description
Technical field
The present invention relates to passenger car fields, and in particular to the front bumper of car.
Background technology
With the development of society, people's lives level is higher and higher, outgoing number is also more and more, and car is in people
Important relatively color is played when trip, the at the same time requirement of user and bus coating producer for car is also more and more.
Since the transport properties of car are very special, the requirement for bus safety is also very high；It is now most of
Car used in bumper be all made of metal, be attached only to together with car, there is no buffer and absorb impulse force
Effect.
The design of this bumper can only avoid some caused damages of slightly scratching in front of protection car, work as chance
To some bursts collision accident when, entire bumper cannot provide cushioning effect for vehicle, the impact force suffered by car inside
It is larger.
Invention content
The present invention in view of the above-mentioned deficiencies in the prior art, provides a kind of coach front bumper, which has
Telescopic folding performance can absorb quite a few impact force when being impacted, and ensure that the safety of car internal staff.
The technical solution adopted by the present invention to solve the technical problems is：A kind of coach front bumper, main includes setting
Anti-collision beam in front of car headstock, anti-collision beam are fixedly connected on the longeron for being symmetricly set on anti-collision beam both sides, vertically
Drawing mechanism is stretched in being provided on anti-collision beam direction, stretches the centre position that drawing mechanism is installed on anti-collision beam, above-mentioned two vertical
Beam is to stretch drawing mechanism as symmetry axis；Further include stretching drawing mechanism and longitudinal beam stretching, extension and the lower cylinder shunk and upper gas for driving
Cylinder.
The piston rod of above-mentioned lower cylinder and upper cylinder is connected on the rear brace rod and longitudinal beam for stretching drawing mechanism.Lower gas
Cylinder and upper cylinder cylinder body are fixedly mounted on car carriage.
It is further：It is above-mentioned to stretch drawing mechanism mainly by upper tappet, lower tappet, left folding arm, right folding arm and control
Center forms, and the connection stretched between drawing mechanism various components is all attached by hinge arrangement, and stretch drawing mechanism and
Connection between longeron is equally to use hinge arrangement.
It is further：Above-mentioned longeron includes the front fixing section being connect with anti-collision beam, the preceding folded section that can be folded and
Folded section afterwards, and the rear fixed section that is attached with bus frame.
It is further：During above-mentioned bus driving, the speed sensor being arranged in anti-collision beam can be surveyed at any time
The speed for trying car, when car speed, which reaches dangerous degree, to be bumped against, speed sensor can be transmitted information by conducting wire
To control centre, control centre can send out information, and upper and lower air cylinders is made to work, and pull tappet up and down, bumper is made to be received
Contracting.
Moreover：The built-in energy-absorption box that can absorb impact force in above-mentioned longeron.
The beneficial effects of the invention are as follows：
Crossbeam can be carried out flexible telescopic machine by coach front bumper of the present invention since automobile front beam crossbeam to be connected with
Structure and longeron, therefore most impact force can be absorbed when being hit, it at the same time can reduce the impact inside car
Power；The present invention is more optimizedly, and intelligentized control method can be carried out by inductor and control centre, adjustment is due to whole by impacting
The energy-absorbing degree of a bumper so that whole process is more scientific and reasonable, can absorb impact force to greatest extent, ensures car
The safety of internal staff.

Specific implementation mode
The specific implementation mode of the present invention is described below in conjunction with the accompanying drawings：
As shown in Figs. 1-5, it illustrates one embodiment of the present of invention, the present invention is used for coach front bumper, as shown in Figure 1,
Main includes the anti-collision beam 1 being set in front of car headstock, and anti-collision beam 1, which is fixedly connected on, is symmetricly set on anti-collision beam 1
The longeron 2 of both sides is provided on 1 direction of anti-collision beam and stretches drawing mechanism 3, stretches drawing mechanism 3 and is installed in anti-collision beam 1
Between position, above-mentioned two longerons 2 are to stretch drawing mechanism 3 for symmetry axis；Further include stretching drawing mechanism 3 and longitudinal beam 2 is stretched for driving
Exhibition and the lower cylinder 5 shunk and upper cylinder 4.
The piston rod of above-mentioned lower cylinder 5 and upper cylinder 4 is connected to the rear brace rod 17 and longitudinal beam 2 for stretching drawing mechanism 3
On.Lower cylinder 5 and 4 cylinder body of upper cylinder are fixedly mounted on car carriage.
It is above-mentioned to stretch drawing mechanism 3 mainly by upper tappet 17, lower tappet 12, left folding arm 16, in right folding arm 11 and control
The heart 13 forms, and the connection stretched between 3 various components of drawing mechanism is all attached by hinge arrangement 10, and stretches drawing mechanism
