Problems solved by technology

[0002]The mercury switch type crash sensor is an important part of the vehicle to trigger the airbag. The existing trigger principle is to throw mercury between the two electrodes through inertia when the car is hit. Between the two electrodes, so as to trigger the airbag; Based on this mercury collision sensor, there is a disadvantage, that is, it has very strong directionality, a sensor only responds to collisions in a specific direction, and a single sensor cannot detect any direction The collision produces a reaction

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] as attached Figures 1 to 9 The shown mercury inertial triggering device for an automobile airbag includes an inverted gyro-shaped mercury inertial triggering container 42, and the top of the mercury inertial triggering container 42 is integrally connected with a vertical spring tube 12 through a throat 33 and coaxial;

[0034] In the mercury inertia trigger container 42, there is a mercury filling cavity 31, in the spring tube 12 is a columnar spring chamber 36, in the throat tube 33, there is a throat channel 34 with a thin vertical middle part and thick upper and lower ends, and the lower end of the spring tube 12 is in contact with the mercury. The upper end of the filling cavity 31 communicates with the throat channel 34 ; the mercury filling cavity 31 is filled with mercury, and the mercury liquid level is just at the middle height of the throat channel 34...

Abstract

The invention discloses a mercury inertia triggering device of an automobile safety air bag, which comprises an inverted gyroscope-shaped mercury inertia triggering container, and the top end of the mercury inertia triggering container is coaxially and integrally connected with a vertical spring tube through a throat tube; a mercury filling cavity is formed in the mercury inertia triggering container, a columnar spring bin is arranged in the spring tube, a vertical throat tube channel with a thin middle part and thick upper and lower ends is arranged in the throat tube, and the lower end of the spring tube is communicated with the upper end of the mercury filling cavity through the throat tube channel; the mercury filling cavity is filled with mercury, and the liquid level of the mercury is just located at the middle height position of the throat pipe channel. The violent collision in any direction can be recognized through one mechanism, and the mechanism is more comprehensive than a single-direction collision mechanism in the prior art.

Description

technical field [0001] The invention belongs to the field of automobile safety. Background technique [0002] The mercury switch type collision sensor is an important part of the vehicle triggering the airbag. The existing triggering principle is to throw mercury between the two electrodes through the inertia when the car is collided, so that the two electrodes are connected, thereby triggering the airbag; based on this One disadvantage of the mercury impact sensor is that it has very strong directionality. A sensor can only respond to collisions in a specific direction, and a single sensor cannot respond to collisions in any direction of the water direction. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a mercury inertia trigger device for automobile airbags, which can identify high-intensity collisions in any direction. [0004] Technical solution: In order to achieve t...
