Abstract
The invention discloses a kind of bumper with guide function, is related to a kind of car insurance bar, and the bumper bar includes sensing part and protection part.Sensing part is arranged on bumper edge, and sensing part is made up of injection non-newtonian liquid membrane vesicle.The beneficial effects of the present invention are：Non newtonian can provide different quasi-viscous effects according to stress difference, different brake responses is made to different degrees of collision with reference to electromechanical braking system, directive wheel can also adjust vehicle body angle in side collision and reduce friction loss, improve the security performance of automobile.
Description
Technical field
The present invention relates to a kind of automobile technical field, more particularly, to a kind of bumper.
Background technology
The protection structure being located at during bumper before and after vehicle body, in the case of colliding, it can protect driver's
Safety.Existing bumper can only protect automobile with the intensity of itself, when sharp impacts occur for the guarantor of automobile
It is extremely limited to protect effect, also resulting in bumper for small collision wears, and causes maintenance cost to rise.
The content of the invention
The purpose of the present invention is to increase bumper in collision to the protecting effect of automobile, while is reduced in small collision pair
The destruction of bumper.
Scheme used in the present invention is：A kind of bumper, the bumper include bumper frame, are oriented to sensing
Wheel, bend directive wheel, system display.
Bumper is connected with being oriented to induction wheel by fixing groove, and each induction wheel that is oriented to works independently, and demolition and maintenance are convenient.
The sensing directive wheel is perfusion non-Newtonian fluid material in diaphragm seal, forms the utricule with certain volume, capsule
Pressure inductor is housed on internal main installation axis of spindle, for detecting the pressure change in utricule.Pressure inductor and in-car
Control display screen connection, when intracapsular pressure is mutated, send alarm.
Control display screen can be connected with the electric mechanical brake system of automobile in the car, in utricule by different grades of
During impact, auxiliary driver makes passive operation, and longer buffer time is provided for driver.
The directive wheel of bumper bending section is made of elastomer, avoids automobile from occurring to rub for a long time with side obstacle
Wipe.

The display screen of 16. display interface device of motion block 13. support frame, 14. rotary shaft, 15. brake disc 17.
Embodiment
Specific implementation method combination accompanying drawing is described below.
With reference to Fig. 1 and 3, bumper is divided into bumper frame 1, bend directive wheel 2, is oriented to induction wheel 3.Bend directive wheel 2
It is made up of high elastic rubber.It is connected by directive wheel mounting hole 8 with bumper frame 1.In automobile turning be connected wall or
It when vehicle rubs, can avoid that scraping event occurs.Can reverse vehicle body in curved skidding excessively at a high speed prevents automobile simultaneously
Go out guardrail.Induction wheel 3 is oriented to be distributed with sector in bumper frame 1.
Induction wheel 3 is oriented to reference to prominent Fig. 2 to be made up of membrane vesicle 7, pressure sensor 6 and live spindle 5.Irrigated in cyst membrane swollen
Plasticity non newtonian liquid, the swollen plasticity non newtonian liquid is using internal viscosity with the rheological behavior material for being increased by rate of shear rate and being strengthened
Material.After bumper is hit, impulsive force, the sticky meeting of non-newtonian liquid can be applied to non-newtonian liquid in membrane vesicle 7
Increase, its rigidity enhancing, internal pressure sensor experience pressure change, and corresponding pressure sensing is sent correspondingly to brake
Instruction.
With reference to Fig. 4, electromechanical braking system is by braking motor 10, shaft coupling 11, brake block 12, brake disc 15.Pressing
When force snesor 6 is by different grades of impact, braking motor provides different brake force torque.Electromechanical braking system body
Product is small, is easy to lay.
With reference to Fig. 5, display is connected by display interface device 16 with electronic mechanical system and pressure sensor 6, display screen
Bumper state is shown on 17, electromechanical braking system can be by display manual-lock, and can pass through display screen
17 directly learn whether automobile wipes the obstacle for encountering surrounding, and bumper is alarmed using contact, therefore blind area is not present.
It is different in different travel speeds under various circumstances, the braking effect of electromechanical braking system according to automobile.
When 2-8Km/h collides, the non-newtonian liquid being oriented in the membrane vesicle 7 of induction wheel 3 will not be hardened, and membrane vesicle 7 can touch with contact
Deformation is hit, causes pressure change in membrane vesicle 7, the pressure change peak of pressure sensor 6 will be converted into for the impulsive force under speed
It is worth scope.The capacity operation of braking motor 10, reach most short braking distance, stop automobile being oriented in the deformation range of induction wheel 3
Firmly.In 40-60km/h, the non-newtonian liquid viscosity in cyst membrane 7 increases sharply speed, is oriented to induction wheel 3 and is hardened, pressure sensing
Device 6 receives faster pressure peak change, and the guiding induction wheel 3 being hardened can also play a protective role.Braking motor 10 provides dimension
The brake force of present speed is held, prevents driver's operational error, by phenomenon of taking throttle as brake, brake, which only allows to slow down, not to be allowed to add
Speed.Keeping away emergency brake simultaneously causes rear-end collision, and brake is served only for limitation and accelerated, decides whether to stop by driver.Speed exists
During 100-120km/h, collision can rupture membrane vesicle 7, and the direct contact-impact of the meeting of pressure sensor 6, pressure sensor 6 spreads out of peak value
Pressure, because speed is higher, when the guiding induction wheel 3 on bumper is destroyed more than 2, braking motor 10 provides emergency brake.To keep away
Exempting from the failure of single pressure sensor 6 causes brakes error in judgement, it is necessary to which 2 pressure above sensor degradations just can emergency brake.
