Therefore, each large host factory starts to update the technology, so that the market competitiveness is enhanced, and the automobile occupation of the market is increased. The traditional safety belt adopts a passive protection method, and when a vehicle is impacted by external force, the safety belt starts to work to protect the safety of a driver and passengers. The safety belt starts to work within a few tenths of a second after an accident, belongs to passive protection, has poor protection effect, and is easy to be damaged by passengers.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an initiative early warning formula car blet device in order to overcome the defect that above-mentioned prior art exists.

The purpose of the utility model can be realized through the following technical scheme:

the active early warning type automobile safety belt device comprises a safety protecting belt, a retractor and an active tightening assembly, wherein the active tightening assembly comprises a tightening motor and a driving wheel unit which is respectively connected with the tightening motor and the retractor in a synchronous driving mode.

Further, still including installing on the automobile body and being used for surveying the detection radar of road conditions information (being the distance information of obstacle and automobile body around) around the automobile body and connecting the detection radar can receive the controller of the obstacle information around the car of processing detection radar feedback, the controller still is connected tighten up the motor.

Furthermore, four groups of detection radars are arranged and are respectively positioned on the peripheral side surfaces of the automobile body.

Furthermore, the controller is also connected with a speed sensor in the automobile, when the controller receives feedback signals of the detection radar and the speed sensor and displays any one of the following driving conditions, the controller controls the tightening motor to work, and after the driving wheel unit drives the retractor to rotate, the safety protecting belt is enabled to be pre-tightened actively and warns a driver;

the driving conditions comprise two driving conditions, namely (A) the vehicle speed exceeds a set value and surrounding obstacles are positioned in a set safety distance of a vehicle body; (B) the automobile runs and the speed of the automobile does not exceed the set value, but the surrounding obstacles accelerate to approach the automobile body to be within the set safe distance. The vehicle speed and the safe distance can be set by self.

Furthermore, the safety protecting belt is also provided with a buckle.

Further, the driving wheel unit comprises a driving wheel coaxially connected with the tightening motor and a driven wheel meshed with the driving wheel and coaxially connected with the retractor.

Furthermore, an intermediate gear is arranged between the driving wheel and the driven wheel.

Further, the retractor and the active tightening assembly are integrated into a whole.

Further, the controller is a conventional controller with a P L C system or the like.

Compared with the prior art, the utility model has the advantages of it is following:

(1) through the setting of the initiative subassembly that tightens up, can be before the traffic accident takes place for the car, can drive the coiler rotation through the initiative subassembly that tightens up, realize tightening up the initiative of safety belt, reduced like traditional safety belt because the too big risk that easily takes place the collision of health displacement volume.

(2) Through the setting of functional unit such as surveying radar, controller, can be through detecting the distance information like vehicle and other barriers around the automobile body, and then judge the risk condition that automobile itself takes place the traffic accident, when the controller judges that the automobile is in the risk that easily takes place the traffic accident, can tighten up motor work with control, realize the pretension to the safety protecting band, and then warn driver's relevant risk, in order to make things convenient for driver's adjustment to go the route or the state of going, the intelligent level of automobile can be improved greatly.

(3) The driving wheel unit adopts a driving wheel, a driven wheel and a structure matched with an intermediate gear, so that when the winding motor works, relevant adjustment can be conveniently transmitted to the retractor, and when the winding motor does not work, the influence of the self pre-tightening state of the retractor on the winding motor can be reduced as much as possible.
