The technical scheme that its technical matters that solves the utility model adopts is: be example with the city motor bus, compartment and chassis or underframe are directly unfixing, and the compartment here mainly refers to take space segment, and the chassis mainly refers to vehicle with respect to the part of taking below the space.Perhaps the chassis mainly refers to load onto the movable stand of wheel Running System, and the compartment refers to the car load part except the movable stand of loading onto the wheel Running System.The laminated rubber post is installed, damper, energy consumer and position-limited lever between compartment and the chassis.Laminated rubber capital end is connected the bottom, compartment, and the bottom is connected on the chassis, relative chassis, compartment is moved, and makes the compartment reset function.And energy consumer mainly plays the energy that the consumption compartment moves relative to the chassis.Damper one end is connected compartment bottom by pin, and the other end is attached on the chassis by pin, and promptly as long as remove the connection of arbitrary end, damper all can be done rotation on the horizontal surface around the pin of the other end.The damping hole of damper is by stepping motor or its switching of solenoid control and aperture.Damping material in the damper can be selected the materials such as siliceous or silica gel of similar solid for use, and strengthening energy dissipation capacity, and when damping hole was closed, damper can not stretch again, the compartment will be not relatively the chassis be moved.
As self-propelled vehiclees such as city motor buss, the passenger just got on the bus foot a bill or near the station prepare to get off navigate within the middle of the passenger in, if driver's acceleration suddenly, emergency braking or sharply turning, because the passenger does not have enough defences, accident such as then bump or fall down easily.So this anticollision of motor vehicles system utilizes the sensors such as wheel speed sensors, acceleration pick-up, engine throttle door sensor and gyroscope of existing ABS system, utilize microcomputer to control, when sensor detects when on certain direction of vehicle bigger rate of acceleration change being arranged, an acceleration, deceleration degree suddenly, bigger promptly will be arranged on this direction, and central controller ECU sends action through processing after receiving signal.Can inform passenger's " carefully " by sound or optical signal on the one hand, make stepping motor or electromagnetic valve action on the damper on the other hand, damping hole is opened, then the compartment can move relative to the chassis buffering along the reversing sense of acceleration/accel, play on the buffered water plane suddenly effect than high acceleration, make the passenger, the passenger who is standing on the city motor bus particularly, preparation is arranged at heart, because of the people has subjective initiative, will or adjust stance and wait the acceleration suddenly of dealing with the driver, sudden stop or sharply turning etc. by handrail.Devices such as bearing circle that the driver handled and acceleration pedal then can be eliminated the influence that sort buffer moves by installing telescopic mounting additional.
For the stability that guarantees that vehicle itself travels, then detecting vehicle as detectors such as gyroscopes when upward slope or descending or rugged road traveling, then do not allow the damping hole of damper to open, and increase the above-mentioned energy consumer and the friction force of bottom surface, compartment by propulsion source, make compartment bobbin movement relatively.
When vehicle is subjected to external vehicular sideview collision or rear-end impact, because sensor measures bigger acceleration/accel or bigger rate of acceleration change, then the central controller controls damping hole is opened to maximum, so, the smaller power of operator's compartment or compartment that just is subjected to the compartment sending a car will move along the direction of being hit, then vacate a part of chassis in collision place, with the chassis collision of sending a car, crimp, absorb collision energy, meanwhile the compartment has cushioned the acceleration/accel of collision because the promotion at send a car compartment or operator's compartment position is then moved to the direction that quilt hits, and has reduced the variation of two car occupant living spaces.And for the collision in car the place ahead, then can utilize detector such as laser radar to detect soon and send a car when head-on crash takes place, do not allow relative chassis, compartment to move forward even big acceleration/accel or rate of acceleration change then occur yet, even move after can making relative chassis, compartment by propulsion source, remain with the energy that next collide with buffering on more chassis in order to making the place ahead, compartment.Consider that the compartment moves a certain distance to either direction on the chassis relatively, so the length and width on chassis can be done greatlyyer than the compartment slightly.And add the steel framed structure of some energy-absorbings around can be on the chassis.Safe position-limited lever then is the amplitude that the restriction compartment moves relative to the chassis.Length and width size as the chassis is not made greatlyyer than the compartment, can detector be installed at vehicle's surroundings, when in detecting the spatial dimension that compartment buffering moves to other object being arranged, can temporarily not allow the compartment sort buffer to move.
The beneficial effects of the utility model are: play that either direction goes out the too big acceleration/accel of terrain suddenly on the buffer motor-car horizontal surface, make the passenger mentality of standing on occupant or the city motor bus that a preparation be arranged earlier, so that performance people's subjective initiative is adjusted sitting posture or stance is dealt with acceleration/accel.And buffering is arranged by energy and acceleration/accel that each side sends a car and collides, reduce the effect of compartment living space distortion.
