Abstract

The utility model discloses an escape glass window at the roof of a bus. The escape glass window comprises a single-chip microcomputer and a stepping motor, wherein an attitude sensor and an impact sensor are connected with a data acquisition card; the data acquisition card is connected with the input end of the single-chip microcomputer; the output end of the single-chip microcomputer is connected with the stepping motor through a stepping motor driving circuit; the stepping motor is arranged on the escape glass window; and the escape glass window is arranged on the roof. The escape glass window is convenient for passengers to escape the site when the rollover accident of an intercity bus occurs; and the passengers do not need to crack glass and do not upwards climb out of the window forcibly, but the passengers only need to climb out of the escape glass window sideways. The escaping time is saved, and for the injured passengers, the effect is more obvious.

Description

A kind of motor bus roof escape glass window

Technical field

The utility model belongs to field of automobile safety, is specifically related to a kind of automobile escape device.

Background technology

That automobile has become is most important in the modern society, use the most general vehicles.Along with the increase of global automobile pollution, also become increasingly conspicuous to problems such as the traffic safety of light, Environmental security, energy shortage, traffic congestions with automobile.At secure context, automobile has become present social one big " killer " especially.Occupy recent " world's Mishap Report " statistics of the World Health Organization, the whole world has 1,300,000 people of surpassing to die from the road traffic accident that causes because of automobile every year in recent years, wounded or disabled number is up to more than 3,000 ten thousand, and promptly the whole world just had 1 people to be killed in an automobile accident in average per 25 seconds, just has 1 people injured or disable in per 1 second.Severe more in China's traffic safety situation.From calendar year 2001 to 2006 year, China has about 100,000 people to die from traffic accident every year, suddenly becomes the first in the world.With after regulation energetically,, but still, still come out at the top above people surplus 7.3 ten thousand though toll on traffic descends to some extent.In recent years, countries in the world government has given general attention to traffic safety technology, and drops into substantial contribution, wishes the utilization by modern high tech method, reduces the generation of traffic accident, and fundamentally reduces the associated death number.

Now the glass for vehicle window of coach is generally less, have in addition be not provided with.When the rollover accident takes place in running passenger vehicle, the passenger fled from and just needed safety hammer to break glass into pieces this moment, fled from by the window of automobile side.People are flurried when accident takes place, and sometimes are not easy to break into pieces glass, and after breaking into pieces, also need upwards firmly climb out of window.

Summary of the invention

At the deficiency that prior art exists, the purpose of this utility model is, a kind of glass window that can escape under motor bus meets accident the situation of traffic accident is provided.

In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:

A kind of motor bus roof escape glass window, comprise single-chip microcomputer and stepper motor, attitude transducer links to each other with data collecting card with shock transducer, data collecting card links to each other with the input of single-chip microcomputer, the output of single-chip microcomputer links to each other with stepper motor by stepper motor driving circuit, stepper motor is installed on the escape glass window, and the escape glass window is installed on the roof.

The utility model also has following technical characterstic:

Described single-chip microcomputer adopts the MC9S12XS128 single-chip microcomputer.

Described attitude transducer adopts the IMEMS attitude transducer.

Described shock transducer adopts the OBTE__LSZ-F03A shock sensors.

The utility model can be used for making things convenient for the passenger to flee the scene under the situation of coach generation rollover accident, does not need the passenger to break glass into pieces, does not also need the passenger upwards firmly to climb window, only needs side to climb out of the lifesaving window glass to get final product.Can save the time of fleeing from, concerning those injured passengers, effect is more obvious.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

The implication of each label is among the figure: 1-attitude transducer, 2-shock transducer, 3-data collecting card, 4-single-chip microcomputer, 5-stepper motor driving circuit, 6-stepper motor, 7-escape glass window, 8-roof.

Below in conjunction with drawings and Examples particular content of the present utility model is done explanation in further detail.

The specific embodiment

Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.

Defer to technique scheme, as shown in Figure 1, a kind of motor bus roof escape glass window, comprise single-chip microcomputer 4 and stepper motor 6, attitude transducer 1 links to each other with data collecting card 3 with shock transducer 2, and data collecting card 3 links to each other with the input of single-chip microcomputer 4, and the output of single-chip microcomputer 4 links to each other with stepper motor 6 by stepper motor driving circuit 5, stepper motor 6 is installed on the escape glass window 7, and the escape glass window is installed on the roof 8.

Attitude transducer 1 adopts the IMEMS attitude transducer, it comprises three-axis gyroscope, three axis accelerometer (being IMU), three synkinesia sensors such as electronic compass, export the angular velocity of calibrating by embedded low-power consumption arm processor, acceleration, magnetic data etc. are carried out athletic posture by the sensing data algorithm based on hypercomplex number and are measured, and output is with the zero shift 3 d pose data of expressions such as hypercomplex number, Eulerian angles in real time.Attitude transducer 1 is positioned near the single-chip microcomputer 4, conveniently is connected with single-chip microcomputer 4, and its effect is whether the identification passenger vehicle turns on one's side.

Shock transducer 2 adopts the OBTE__LSZ-F03A shock sensors.This sensor is a resistance-strain type of dynamometer sensor, is quick on the draw, and shock transducer needs two, is installed in the left and right sides of vehicle body respectively, and its effect also is whether the identification passenger vehicle turns on one's side.

Data collecting card 3 adopts the DAQ capture card.The DAQ capture card is a precision signal picker based on usb bus.Profile is similar to USB flash disk, but its inside integrated the input and output bidirectional digital interface of high-speed AD and complex function.It can gather ± single-ended voltage signal between the 5V, and sample rate is up to 100Ksps, and built-in amplifier, can multiplication factor be set by the gain resistor of outside.
