Description

A kind of car rollover safety device
Technical field
The utility model belongs to bus safety protection technology field, and in particular to a kind of car rollover safety device.
Background technology
In recent years, since car carrying number is more, safe escape of saving oneself setting is incomplete, often car traffic accident meeting Cause more heavy casualties, people also higher and higher to the attention rate of car crashworthiness.
In all traffic accidents, car rollover often leads to heavy casualties, belongs to major traffic accidents.Car rollover thing In therefore, topple over side occupant's chance of injury, degree is significantly larger than other side, therefore, the anti-side for improving car turns over performance, ensures side The life security for turning over occupant in accident has become a very important project.Currently, China refers to Economic Commission for Europe's system Fixed car rollover (ECE R66) regulation, is formulated《The regulation of car superstructure intensity》(GB/T17578-1998) state Family's standard, and enforce, the anti-side to improve domestic car turns over performance.According to laws and regulations requirement, when car is turned on one's side, vehicle Body structure can not invade the living space of occupant.Currently, domestic bus and coach enterprise is mainly adopted to meet this laws and regulations requirement With increasing, the sectional dimension of body side wall structure, increase section thickness, reinforcing plate or adjustment office are pasted in outside in side wall pillar The schemes such as portion's connector type of attachment.Said program not only increases the weight of body structure, and turns over performance to the anti-side of car Also it is not significantly improved, such design means do not meet the theory of energy-saving and emission-reduction and body lightening, due to traditional car Structure type limited, it is inconvenient outside gusset to increase endergonic structure, it is therefore necessary to study a kind of car rollover protective device It improves the rollover safety of car, while providing space in a safer cabin as much as possible for passenger.
Invention content
For car during rollover, car gusset can not design effective endergonic structure, and bus occupant at this stage Cabin is provided only with escape and saves oneself design mostly, does not fully consider the injury during directly reducing collision rollover suffered by passenger Problem, the purpose of this utility model is to provide a kind of car rollover safety device, on the basis for not changing former body structure On, car rollover safety is improved by using lifting type activity luggage compartment door, air-bag module, in car rollover event When generation, coach body structure deformation and the protection to occupant's progress to a certain extent are reduced, is realized to the further of passenger Protection while the trend for meeting body lightening design.
To achieve the goals above, the technical solution adopted in the utility model is a kind of car rollover safety device, Including be arranged on the luggage compartment door of car both sides bottom make hatch door be unfolded hatch door ejecting mechanism and be set in hatch door Air-bag module on the inside of side and vehicle window near ventilation opening;
Hatch door ejecting mechanism includes the cylinder body that bottom end is hinged on floor crossmember, and exsertile piston is provided in cylinder body The external part of bar, piston rod is hinged on for hatch door to be pushed open to the connecting rod enumerated, and connecting rod one end is hinged in luggage compartment, another End is hinged on hatch door inner wall.
Hatch door ejecting mechanism further include the electromagnet assembly that bottom is set in cylinder body, connection on the piston rod with electromagnet Permanent magnet that component is oppositely arranged and relay for controlling electromagnet assembly energized state is connect with electromagnet assembly Component.
