Abstract

The invention relates to the technical field of driving safety equipment, and discloses a roof rack for preventing a vehicle from rolling. This prevent roof-rack that vehicle rolled, expansion through connecting rod and railing, prop up the car, increase the degree of difficulty that the car rolled, simultaneously, the slide through low frictional force, the kinetic energy that breaks lateral shifting changes into the process of kinetic energy that rolls, and then avoided the phenomenon of rolling with higher speed of car, and then reduced the injury to the passenger when the car rolls, improve the security of car, secondly, when the car detects that horizontal vehicle is close, expand from triggering connecting rod and railing, horizontal vehicle strikes connecting rod and slide earlier, make connecting rod and slide warp and destroy, in time absorb partly kinetic energy, reduce the injury of side direction striking.

Description

Roof rack for preventing vehicle from rolling

Technical Field

The invention relates to the technical field of driving safety equipment, in particular to a roof rack for preventing a vehicle from rolling.

Background

The vehicle rolls with a certain probability when out of control, according to statistics, when rolling occurs, the fatality rate reaches 10%, and the injury rate reaches 50%, namely when rolling occurs, the safety of passengers in the meeting vehicle has a greater threat.

The vehicle rolls and hinders the vehicle to slide laterally by the barrier generally, make its lateral slip become to roll, know from the law of conservation of mass, kinetic energy when the car moves can change into the rotatory kinetic energy of vehicle when the car rolls, and know from the conservation of angular momentum, radius along with the car rolls reduces, vehicle roll speed can be the trend of accelerating, consequently, can see when the vehicle takes place to roll, the vehicle can sharply accelerate and roll after the first circle of rolling, just can reduce gradually after rotatory to the maximum speed, it is also one of the big reasons of threat to passenger's safety that rolls fast.

Secondly, when a traffic accident occurs, the fatality rate of the side of the automobile caused by collision is far higher than that of the front, and the side protection capability of the automobile needs to be further improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments based on the implementation of the present invention belong to the protection scope of the present invention.

Referring to fig. 1-2, a roof rack for preventing a vehicle from rolling comprises a supporting base station 1, the supporting base station 1 is fixedly installed on a roof, an angle adjusting structure 8 is arranged between the supporting base station 1 and a connecting rod 2 and can actively adjust the angle of the connecting rod 2, the supporting base station 1 is movably connected with the connecting rod 2, the connecting rod 2 is movably connected with a railing 3 through a rotating joint 4, the connecting rod 2 and the railing 3 are stored on the roof through folding, when a vehicle-mounted sensor senses that the vehicle rolls on the side, a vehicle-mounted ECU controls the rotating joint 4 to rotate, so that the connecting rod 2 and the railing 3 are horizontal, the folding can ensure enough extension length and is convenient to ensure structural strength, a sliding plate 5 is fixedly connected to the far end of the railing 3, rollers are arranged on the sliding plate 5, when the railing 3 abuts against the roof, friction can be reduced, the railing 3 slides along the ground, the kinetic energy of the vehicle is converted into kinetic energy of sliding and transverse movement, the vehicle rolling is interrupted, the railing 3 is horizontally arranged, the railing 3 is fixed on the roof through a fixing rod 6, the railing 3 and the fixing rod 6 are fixedly connected through a shearing pin 7, a disassembling trigger 9 is arranged between the railing 3 and the fixing rod 6, and the shearing pin 7 is fixedly connected through a shearing pin 7, when the vehicle is triggered, and the disassembling trigger 9 is triggered to enable the railing 3 to freely roll on the roof.

Referring to fig. 3, two sets of the connecting rods 2, the railings 3 and the sliding plates 5 are respectively arranged at two ends of the roof, the two sets of the railings 3 are fixedly connected through the connecting beam 10, the whole body is taken as a whole, the support provided during sliding is more stable, and the fixing rods 6 are arranged on the connecting beam 10, so that the damage to the railings 3 and the connecting rods 2 is reduced, and the stability during sliding is improved.

Wherein, the trigger 9 that disintegrates is the gasbag of tiling at the roof, be equipped with gas generator in the trigger 9 that disintegrates, the trigger 9 that disintegrates produces a large amount of gases when turning on one's side, jack-up railing 3 breaks shear pin 7, the upper end of the trigger 9 that disintegrates is the leather, support base station 1 and the up end fixed connection who disintegrates trigger 9, because roof structural strength is lower, aerify through the gasbag, on the trigger 9 that disintegrates of support base station 1 action force effect, the trigger 9 that disintegrates disperses the action force to whole roof again, the roof damages when avoiding.

The grounding end of the sliding plate 5 is arc-shaped and vertical to the side face, the sliding plate 5 is provided with a plurality of groups of rollers along the arc face, contact with the ground is guaranteed through the arc, and friction force of transverse movement of the rollers is reduced.

Referring to fig. 4, the support base 1 is connected to a moving rail 12 disposed transversely, the moving rail 12 is disposed on a vehicle roof, two ends of the moving rail 12 are respectively provided with a first locking member 11 and a second locking member 14 capable of locking the support base 1, a locking tongue of the first locking member 11 can actively retract to unlock the support base 1, the support base 1 is fixedly connected to an elongated tension spring 13, when the first locking member 11 contracts, the tension spring 13 rapidly pulls the support base 1 to the other side, and the second locking member 14 locks and fixes the support base 1.

The working principle and the working process of the invention are as follows:

when the vehicle runs at high speed and turns over on the ground, the gas generating device of the trigger piece 9 is triggered to generate a large amount of gas, the shearing pin 7 is broken, the supporting base station 1 and the rotating knot 4 rotate simultaneously, the connecting rod 2 and the railing 3 are opened to become horizontal, the position of the supporting base station 1 is controlled according to the side turning reverse direction of the vehicle, the connecting rod 2 and the railing 3 are unfolded, the sliding plate 5 is grounded, the vehicle is supported from one side, the rolling diameter of the vehicle is increased, the continuous rolling difficulty of the vehicle is increased, meanwhile, the transverse rolling momentum is changed into the transverse moving momentum due to the fact that the friction force of the sliding plate 5 is small, the conversion of the momentum of the vehicle is interrupted, and therefore the vehicle is prevented from rolling in an accelerating manner, when the vehicle is located on a downhill slope or uneven ground, the vehicle can roll and jump repeatedly, the rolling and the falling of the vehicle is stopped, and the vehicle cannot roll in an accelerating manner.
