Abstract
The invention relates to an aerated vehicle safe belt. One end of H-shaped safe ban is connected to the base above the box via safe band support axle; two boxes both contain left and right cylinders; pistons of two cylinders are connected to one end of each connecting rod via pin; another end of connecting rod via pin is eccentrically connected to one end of safe band; another end of safe band is mounted with pressure sensors at two inner sides; two cylinders via tubes are connected to the electromagnetic steering valve; the air inlet of valve is connected to the pressure adjusting valve and air source switch valve; the air outlet of steering valve is connected to the sound adsorption throttle valve; the invention converts the vertical motion of cylinders into rotation of safe band; two sides of safe band via aeration controller can automatically compress two sides of user chest, and via the pressure sensors adjust the force. The invention has simple structure.
Description
Technical field
The present invention relates to a kind of Pneumatic automobile safety belt.
Background technology
At present, existing armstrong's patent motorcycle safety band is made up of parts such as a high-intensity fabric belt and wind spring, ratchet, inhibiting device, snap closes, it can freely stretch at ordinary times, at emergency braking with when unforeseen circumstances such as bumping, can limit passenger's body and move.But this safety strap need manually be finished, and easily because carelessness or idea of leaving things to chance and do not fasten one's safety belt, thereby might bring life danger.
Summary of the invention
The purpose of this invention is to provide mode of motion is that up-and-down movement is converted into a kind of Pneumatic automobile safety belt that rotatablely moves, and energy volitional check passenger's health moves, to overcome the defective that above-mentioned motorcycle safety band exists.
The technical solution adopted for the present invention to solve the technical problems is:
One end of the safety strap that horizontal " H " is arc is rotationally connected with the support of harness supports rotating shaft and both sides box body top, two cylinders about being equipped with respectively in two box bodys, piston rod on two cylinders is rotationally connected with separately connecting rod one end respectively with latch, the other end of two connecting rods is connected with an end of safety strap is eccentric by pivot pin, pressure sensor is equipped with in the other end two inboards of safety strap, two cylinders connect solenoid directional control valve by tracheae, the inlet end of solenoid directional control valve connects pressure regulating valve and gas source switch valve, and the outlet side of solenoid directional control valve connects the noise reduction flow regulating valve.
Inflatable packer is equipped with in arc safety strap two inboards of described horizontal stroke " H ".
The beneficial effect that the present invention has is:
The up-and-down movement of two cylinders is converted into rotatablely moving of the arc safety strap of horizontal stroke " H ", the both sides of safety strap can compress both sides, occupant shirtfront automatically by air control unit, and can also be by safety strap two inside pressure sensors energy automatic compensation thrust.The present invention is simple in structure, easy to use, and handsome in appearance.
Description of drawings
Fig. 1 is the safety strap structural representation;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the air control unit schematic diagram.
Among the figure: 1. safety strap, 2. pressure sensor, 3. inflatable packer, 4. harness supports rotating shaft, 5. pivot pin, 6. connecting rod, 7. latch, 8. piston rod, 9. turnover tracheae, 10. cylinder, 11. box bodys, 12. support, 13. solenoid directional control valves, 14. noise reduction flow regulating valve, 15. pressure regulating valves, 16. gas source switch valves.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the present invention is rotationally connected at the end of horizontal " H " arc safety strap 1 support 12 with harness supports rotating shaft 4 and both sides box body 11 tops, two cylinders 10 about being equipped with respectively in two box bodys 11, piston rod 8 usefulness latches 7 on two cylinders 10 are rotationally connected with separately connecting rod 6 one ends respectively, the other end of two connecting rods 6 is connected with an end of safety strap 1 is eccentric by pivot pin 5, pressure sensor 2 is equipped with in the other end two inboards of safety strap 1, two cylinders 10 connect solenoid directional control valve 13 by tracheae 9, the inlet end of solenoid directional control valve 13 connects pressure regulating valve 15 and gas source switch valve 16, and the outlet side of solenoid directional control valve 13 connects noise reduction flow regulating valve 14.
Principle of work of the present invention is:
As shown in Figure 3, car door opening, high pressure gas in the air compressor enter from the B passage of solenoid directional control valve, B ' the passage output of solenoid directional control valve, steam cylinder piston is withdrawn under pneumatic action, rotate by latch 7 drivening rods 6, connecting rod 6 promotes safety strap 1 by pivot pin 5 and rotates around harness supports rotating shaft 4, thereby opens safety strap 1.
As shown in Figure 3, closing of the door, high pressure gas in the air compressor enter from the A channel of solenoid directional control valve 13, the output of solenoid directional control valve A ' passage, steam cylinder piston stretches out under pneumatic action, rotate by latch 7 drivening rods 6, connecting rod 6 promotes safety strap 1 by pivot pin 5 and rotates around harness supports rotating shaft 4, thus closed safe band 1.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
