Description

Passenger protection device in the event of a car crash.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body, and more particularly, to an occupant protection apparatus in a collision of a vehicle that can protect drivers and passengers in a cabin from impact during a front and rear collision of a vehicle.

In general, an automobile body has a monocoque structure in which a frame and a body are integrally manufactured to reduce weight and increase body rigidity. That is, the body of the monocoque structure is a front frame and each side frame to protect the engine unit, front wheel suspension, radiator, steering gear box, etc. in the event of a collision, and one side of the front frame is shocked to protect the cab against impact A crush panel is installed to absorb the water. On both sides of the upper end of the crush panel, front pillars supporting the roof panel and fixing the front window are respectively installed at both front ends of the windshield.

Center pillars for supporting the roof panel and the door are respectively installed at the left and right centers of the vehicle, and rear pillars for supporting the roof panel and fixing the rear window are provided at the rear and right rear ends of the vehicle. In the rear of the vehicle, a rear panel is installed for installing a trunk.

The above-mentioned monocoque car is severely distorted in the front and rear due to collision with other cars while driving or stopping the vehicle, and the driver and passengers in the cabin are severely injured due to the impact, especially the frontal collision of the car. When the engine is pushed into the cabin, the driver had a problem that the lower body is severely damaged and crippled.

In order to solve the above problems, an object of the present invention is to separate the vehicle body into the front part, the rear part, the passenger compartment and then install and fix the vehicle to protect the driver and passengers from impact during the front and rear collision of the car. To provide occupant protection in the event of a crash.

Another object of the present invention is to provide an occupant protection device in the event of a collision of a vehicle which can prevent the lower body part of the driver from being severely damaged during the front collision of the vehicle.

Still another object of the present invention is to provide an occupant protection device in the event of a collision of a vehicle that can implement a complete safety system of the vehicle.

In order to achieve the above object, the vehicle body structure of the present invention is separated into the front part and the cabin and the rear part so that the driver and passengers can be pushed upwards with the impact force upon impact on the front part or the rear part of the car. It features a protective box.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a perspective view showing the structure of a vehicle that can protect the occupant during the front and rear collision according to an embodiment of the present invention. Figure 2 is a side view showing the structure of a vehicle that can protect the occupant during the front and rear collision according to an embodiment of the present invention. 3 is a cross-sectional view of part A showing a state in which the front part and the rear part of the cabin and the vehicle according to the preferred embodiment of the present invention are coupled to each other by welding, and FIG. 4 is a cabin according to the preferred embodiment of the present invention; A cross-sectional view of part A showing a state in which the front part and the rear part of the vehicle are coupled to each other by a collapsible pin. 5 is a schematic view showing a state in which the cabin is operated in the upper direction by the impact force during the front and rear collision of the vehicle according to an embodiment of the present invention.

As shown in Figures 1 and 2, the vehicle body has a front part 10 consisting of a front frame, a side frame and a crush panel, a rear part 14 consisting of a rear panel and a trunk, and a cabin ( 12) and the bottom portion 22 which connects the front portion 10 and the rear portion 14 at the same time to seat and support. In addition, between the front portion 10 and the rear portion 14 is provided a passenger compartment 12 composed of a front pillar, a center pillar, a roof panel, a floor panel and the like.

At this time, the front portion 10, the rear portion 14 and the passenger compartment 12 of the vehicle has the impact force to protect the driver and passengers in the event of a collision with the front portion 10 or the rear portion 14 of the vehicle. The plane 12 is inclined so as to be in contact with each other so as to slide in an upward direction while sliding. In addition, the cabin 12, the front portion 10, and the rear portion 14 and the bottom portion 22, as shown in Figure 3, the impact force when the car crashes into more than 40km / h ~ 50km / h Due to this, the front portion 10 and the rear portion 14 and the bottom portion 22 are separated from each other by spot welding.

Alternatively, as shown in FIG. 4, the cabin 12, the front part 10, the rear part 14, and the bottom part 22 may have the impact force when the vehicle collides with 40 Km / h or more and 50 km / h or more. Due to this, a plurality of collapsible pins may be coupled to each other so as to be separated from the front part 10 and the rear part 14 and the bottom part 22.

Referring to the operation state of the occupant protection device when the collision of the vehicle according to an embodiment of the present invention as described above are as follows.

First, as shown in FIG. 2, the vehicle travels at a constant speed. Thereafter, when another vehicle collides with the front portion 10 of the vehicle, as shown in FIG. 5, the front portion 10 is crushed to absorb shock and the other collision energy is converted into an impact force to the cabin. It acts on the (12) side.

Then, due to the impact force, the cabin 12 is separated from the front part 10 and the rear part 14 and the bottom part 22 and pushed upwards by a sliding motion, and at the same time the front part 10 The engine installed in the) is moved to the place where the cabin 12 is installed, so that the lower part of the driver of the cabin 12 is not damaged.

On the contrary, when another vehicle collides with the rear portion 14 of the vehicle, as shown in FIG. 5, the rear portion 10 is crushed to absorb shock and the other collision energy is converted into an impact force so that the cabin 12 ) Side.

Afterwards, the cabin 12 is separated from the front part 10 and the rear part 14 and the bottom part 22 due to the impact force, and is pushed upwards by the sliding motion. Drivers and passengers on board will not suffer any damage.

Here, even when another vehicle collides with the front portion 10 and the rear portion 12 of the vehicle at the same time, the above-described operation is performed, so that drivers and passengers of the cabin 12 may not be damaged from impact. do.

As described above, the occupant protection device in case of collision of the vehicle according to the embodiment of the present invention is separated from the vehicle body into the front part, the rear part, the passenger compartment, and is fixed by welding or collapsible pins before and after the collision of the vehicle. Due to the impact force generated at the time, the cabin is pushed upwards to protect the driver and passengers from the impact, and also to prevent the driver's lower body from being severely damaged during the front collision of the vehicle. .
