The object of the present invention is to provide a kind of bumpers to make automobile to solve the above-mentioned problems of the prior art
The protective capability of goers outside vehicle is improved, vehicle causes serious injury to pedestrian when avoiding colliding.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Fig. 1-Fig. 4 is please referred to, Fig. 1 is the structural schematic diagram of bumper of the invention, and Fig. 2 is that automobile of the invention is protected
The schematic diagram of the cutaway section of dangerous thick stick, Fig. 3 are the schematic diagram when air inlet of bumper of the invention is opened, and Fig. 4 is this
Schematic diagram when the air inlet bore closure of the bumper of invention.
The present invention provides a kind of bumper, including outer casing 1, padded coaming 2 and anti-collision beam, and padded coaming 2
Between outer casing 1 and anti-collision beam, outer casing 1 has lug boss 3, lug boss 3 and fender towards the side of padded coaming 2
Material 2 is connected, and padded coaming 2 can be compressed when by external force collision.Bumper of the invention, 1 direction of outer casing
Lug boss 3 is arranged in the side of padded coaming 2, and outer casing 1 is made of flexible plastic material, and lug boss 3 enhances outer shield
The deformability of plate 1, in Vehicle-pedestrian impact, outer casing 1 is arranged lug boss 3 and is allowed to more flexible, can preferably delay
Impact force is solved, protects pedestrains safety to greatest extent.
The bottom of outer casing 1 is provided with extension board 4, and extension board 4 is horizontally disposed and extends towards vehicle body direction, outer casing 1
Top and bottom be respectively provided with anticollision gasket 5, anticollision gasket 5 is made of flexible material.The bottom of outer casing 1 is provided with extension board
4, extension board 4, which can be avoided the foreign matters such as stone in vehicle traveling process and be taken up, damages engine, provides for automobile engine more
One protects again；Anticollision gasket 5 is respectively provided in the top and bottom of outer casing 1, the anticollision gasket 5 of the bottom setting of extension board 4,
Extension board 4 can be protected when automobile backing, avoid extension board 4 from scratching damage, the anticollision gasket 5 at 1 top of outer casing is in automobile support
When bottom, it can be avoided protective plate and air-inlet grille for automobile or hard collision occur for preceding cover, auto parts and components are protected, by backing pair
The damage of automobile minimizes.It should be noted that also setting up the structures such as fog lamp hole and tow hook cover, Yin Benfa on outer casing 1
The bright improvement for not being related to carrying out this, details are not described herein again.
Wherein, the one side of lug boss 3 towards padded coaming 2 is cambered surface, and lug boss 3 is cambered surface, reduces stress and concentrates, at this
In specific embodiment, the quantity of lug boss 3 is two, has gap between two lug bosses 3, the quantity of padded coaming 2 with
The quantity of lug boss 3 is consistent and corresponds, and padded coaming 2 is Nian Jie with lug boss 3 to be connected.It is worth noting that, lug boss 3
Both ends and 1 rounding off of outer casing, reduce vehicle traveling process in windage.
In order to increase the contact surface of lug boss 3 Yu padded coaming 2, the face that lug boss 3 is connect with padded coaming 2 is plane,
The contact surface of lug boss 3 and padded coaming 2 is plane, increases the contact area of the two, so that vehicle when hitting, delays
Its deformation effect absorption collision energy can be played as much as possible by rushing material 2, protect pedestrian and driver.
Specifically, when automobile engine runs at high speed, air inflow demand increases, to meet engine charge need
It asks, air inlet 6 is also set up on outer casing 1, returning face plate 7 is set at air inlet 6, returning face plate 7 is rotatablely arranged at outer casing 1

When air inflow demand is lower, the rotation of returning face plate 7 blocks air inlet 6.
More specifically, shaft is arranged in the inside of returning face plate 7, bearing block is arranged in the inside of outer casing 1, and shaft passes through bearing block
Be connected with power source transmission, bearing be set between shaft and bearing block, power source can drive shaft movement, drive returning face plate 7
The open and close of air inlet 6 are realized in rotation, convenient for control.
In this embodiment, driven gear is arranged in one end that shaft stretches out bearing block, and the output end of power source is set
Driving gear is set, driven gear is meshed with driving gear, and power source controls pivot by gear drive, and gear drive is quasi-
Really, convenient for accurate control, transmission efficiency is high, and compact-sized, is easily installed.
In addition, in order to prevent under 6 closed state of air inlet, dust impurity by the gap between air inlet 6 and returning face plate 7 into
Enter, seal washer is arranged in the edge of air inlet 6, and seal washer is set to the inside of outer casing 1, when preventing air inlet 6 from closing
Dust enters machine filter before engine, prolonging service life of filter elements.
Further, air inlet 6 and returning face plate 7 are set between lug boss 3 and extension board 4, realize engine bottom into
Gas improves engine efficiency in conjunction with advance gas phase.
Further, outer casing 1 is made of glass steel material, and outer casing 1 is made of fibre reinforced plastics, can make
It paints in the process, avoids the problem that needing touch-up paint appearance after outer casing 1 scratches, in addition, 4 one of outer casing 1 and extension board
Molding improves overall structural strength.
Lug boss 3 is arranged towards the side of padded coaming 2 in bumper of the invention, outer casing 1, and outer casing 1 is by having
Flexible plastic material is made, and lug boss 3 enhances the deformability of outer casing 1, in Vehicle-pedestrian impact, outer casing
1 setting lug boss 3 is allowed to more flexible, can preferably alleviate impact force, protect pedestrains safety to greatest extent.At the same time,
The bottom of outer casing 1 is provided with extension board 4, and extension board 4 can be avoided the foreign matters such as stone in vehicle traveling process and be taken up damage
Engine provides more one for automobile engine and protects again；Anticollision gasket 5, extension board are respectively provided in the top and bottom of outer casing 1
The anticollision gasket 5 of 4 bottom setting, can protect extension board 4 in automobile backing, extension board 4 is avoided to scratch damage, outer casing
The anticollision gasket 5 at 1 top can be avoided protective plate and touch with air-inlet grille for automobile or preceding cover generation hardness in automobile backing
It hits, protects auto parts and components, backing minimizes the damage of automobile.In addition to this, outer casing 1 also sets up air inlet 6,
When air input of engine by air demand increases, additional-air inlet can be used as, enhance engine efficiency.
