Description

Main airbag with vibration reduction function

Technical Field

The utility model relates to an automobile parts, especially a main gasbag from taking damping function.

Background

The airbag is used as an auxiliary configuration for passive safety of the vehicle body, and is increasingly emphasized by people. When the automobile collides with an obstacle, namely primary collision, a passenger collides with an inner component of the automobile, namely secondary collision, and the air bag rapidly opens an air cushion filled with air after the primary collision and before the secondary collision, so that the passenger moves due to inertia and then "pounces on the air cushion", thereby alleviating the impact on the passenger, absorbing collision energy and lightening the injury degree of the passenger.

The air bags are distributed in the front (front passenger compartment) in the vehicle, the side of the front row and the rear row in the vehicle and the roof. (supplementary Inflatable Restration System SRS for short) Chinese transliteration should be "auxiliary Inflatable Restraint System". The vehicle-mounted passenger car collision safety protection device aims to reduce the injury degree of passengers in secondary collision due to inertia after car collision.

However, the existing air bag lacks a related vibration damping structure, and the main air bag can be integrated with the vibration damping structure to reduce the vibration of the steering wheel.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, which show fig. 1-3, and a primary airbag with a damping function, and the structure and function of each component of the present invention will be described in detail.

First, looking at an airbag frame 1 for fixing an airbag, the airbag frame 1 mainly comprises an airbag support 102, a fastener 106 is arranged on the airbag support 102, the fastener 106 can fix and disassemble the airbag support 102 and an airbag cover 101, a generator 103 is installed at the bottom of the airbag frame 1, the generator 103 is used for starting an airbag to work, and the airbag frame 1 fixes the generator 103 at the bottom through the matching of nuts 105 and fixing rings 104 at 4 corners.

Then, looking at the horn bracket 2 arranged below the airbag frame 1, the horn bracket 2 is mainly used for fixing a horn, a horn spring 201 is arranged on the horn bracket 2, the pressed length of the horn spring 201 can be adjusted by an adjusting nut 203 at the bottom of the horn bracket 2, a clamping hook 202 is arranged at the bottom of the horn bracket 2, and the whole main airbag structure can be clamped and arranged on a steering wheel through the clamping hook 202.

Finally, we introduce the damping structure 3 that sets up between gasbag frame 1 and horn bracket 2, it mainly comprises damping pad 302, gasket seat 301 and gasket knot 303, damping pad 302's outside is the recess design, and damping pad 302's top is provided with gasket seat 301, and gasket knot 303 sets up in damping pad 302 and gasket seat 301 and is close to the one side of being responsible for, and gasket seat 301 and damping pad 302 are linked together in two directions from top to bottom to gasket knot 303, and horn bracket 2 joint is in damping pad 302's recess, further fixes damping pad 302. 3 are the damping structure 3 of triangle-shaped setting installation, the vibration of automobile body passes through the tubular column and transmits the steering wheel, during the main gasbag, the main gasbag is through the three damping structure in picture drawing position, reduce the vibration of main gasbag and steering wheel, the vibration in-process, the damping pad among the damping structure 3 warp, whole gasbag frame 1 and horn bracket 2 form a whole, similar big damping piece, thereby eliminate or absorb the vibration that transmits to the steering wheel from whole car, and then reduced the sense of shaking, can play very big lifting action to the body sense at the driving.
