Abstract
The utility model provides a steering wheel collapsing control device, which comprises a steering wheel, a steering wheel pipe string arranged under the steering wheel, an air bag module arranged on the steering wheel and facing a driver, and an air bag module control unit electrically connected with the steering wheel pipe string and the air bag module and used for determining the crash severity. The air bag module control unit sends signals to the steering wheel pipe string and the air bag module. {EN3}>The air bag module control unit comprises a sensor and a microprocessor mutually coupled with each other. The air bag module comprises an air bag and a gas generator mutually connected with each other. The steering wheel collapsing control device is used for the real-time monitoring of the acceleration of a vehicle and the real-time orientation of the collapsing of a steering wheel pipe string. Due to the adoption of the steering wheel collapsing control device, the start time of the collapsing of a steering wheel pipe string can be accurately controlled.
Description
Technical field
The utility model relates to a kind of control setup, particularly a kind of bearing circle crumple control setup.
Background technology
Along with people in recent years to the improving constantly of automotive safety understanding, car load maker also more and more payes attention to the design of passive security.In order to improve the safety performance of vehicle body, car load factory has adopted crumple formula safeguard construction vehicle body and deformable seat, and common configuration devices such as safety strap pretension, a plurality of safety air bag and crumple formula bearing circle.The application of these devices; Make vehicle when bumping; Can absorb Impact energy through vehicle body deformation, the constraint occupant stops the occupant in driving compartment, to move, and reduces the impulsive force that the people receives in the collision process; Reduce the modes such as injury of secondary collision, passenger and pedestrian are protected.
Wherein the crumple formula bearing circle of Purely mechanical can't accurately be held the run up time of bearing circle tubing string crumple; Realize starting exactly crumple; Need the external electrical control unit, in the prior art, application number is 200810111160.8 Chinese utility model patent; It provides a kind of safety air bag signal intercepting system, obtain air bag ignition signal, make and add safety device and can in time start the crumple of bearing circle tubing string.But do the expansion effect that influences air bag in the process of intercepting like this, maloperation also takes place easily, have certain signal errors, and need add wire harness and device, wire harness is more complicated, and control unit is many more, and integral vehicle cost is just high more.
The utility model content
The purpose of the utility model is to provide a kind of crumple formula control unit that need not to add, and obtains the timely and startup crumple bearing circle crumple accurately control setup of crumple and ignition signal.
For solving the problems of the technologies described above, the utility model bearing circle crumple control setup comprises: bearing circle; Be located at the bearing circle tubing string under the bearing circle; Air bag module is arranged on the said bearing circle and towards navigating mate;
The air bag module control unit, this control unit is electrically connected with bearing circle tubing string and air bag module, is used to judge the order of severity of collision, and sends signal to bearing circle tubing string and said air bag module.
Said air bag module control unit comprises sensor, the microprocessor that intercouples; Said air bag module comprises interconnective safety air bag and gas generator.
For the order of severity of auto against, when Automobile Collision Velocity surpasses 23 kilometers/hour positive rigid collision intensity, then think serious collision.
The utility model is by the crumple of safety air bag control unit direct control bearing circle tubing string.In safety air bag control unit working process, vehicle acceleration is monitored in real time, simultaneously the crumple of direction coil pipe post is led in real time, accurately control the crumple run up time of bearing circle tubing string.According to the speed of a motor vehicle, signals such as sensor through the computing of safety air sac controller, draw the crumple run up time and the execution of bearing circle tubing string more exactly.
In addition because the safety air bag control unit also has the collision recognition function, adopt the method to avoid sudden stop simultaneously or collide error starting bearing circle tubing string crumple under the situation such as not serious; By the crumple of safety air bag control unit direct control bearing circle, do not need the intercept signal system, do not need the crumple of add-on device control bearing circle yet; The time that starts crumple is drawn according to the actual collision data operation by the safety air bag control unit, has guaranteed to start accuracy, promptness and the reliability of crumple.
Description of drawings
Fig. 1 is the utility model bearing circle crumple control setup control module figure;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model bearing circle crumple control setup is done further explain.
Like Fig. 1 and shown in Figure 2, the utility model bearing circle crumple control setup comprises: bearing circle 1; Air bag module 2 is arranged on the bearing circle 1 and towards navigating mate; Air bag module control unit 3 is used to judge the order of severity of collision, and is responsible for sending signal to bearing circle tubing string and air bag module 2.
Air bag module control unit 3 comprises sensor, the microprocessor that intercouples; Air bag module 2 comprises interconnective safety air bag and gas generator.
The utility model bearing circle crumple control setup is the most rational with the signal that transmits as the crumple signal that starts the bearing circle tubing string.Crumple by air bag module control unit direct control bearing circle tubing string.In air bag module control unit working process, vehicle acceleration is monitored in real time, simultaneously the crumple of direction coil pipe post is led in real time, accurately control the crumple run up time of bearing circle tubing string.According to the speed of a motor vehicle, signals such as sensor through the complex calculation of safety air sac controller, draw the crumple run up time and the execution of bearing circle tubing string more exactly.
In addition because safety air sac controller has the collision recognition function, adopt the method to avoid sudden stop simultaneously or collide error starting bearing circle tubing string crumple under the situation such as not serious; By the crumple of full air bag module control unit direct control bearing circle, do not need the intercept signal system, do not need the crumple of add-on device control bearing circle yet; The time that starts crumple is drawn according to the actual collision data operation by safety air sac controller, has guaranteed to start accuracy, promptness and the reliability of crumple.
