Description

Front side reinforcement structure of car {STRUCTURE FOR REINFORCING FRONT SIDE PART OF CAR}

The present invention relates to a front side reinforcement structure of a vehicle, and more particularly, to absorb the impact applied to the front side part in the event of a collision of the vehicle as much as possible, and to prevent the front side part from penetrating into the passenger compartment and being transferred from the engine. A front side reinforcement structure of a vehicle to absorb shocks.

In general, the car's components can be divided into chassis and body. The body is made up of a cabin and a storage box, and is a part for carrying a person or a cargo, and corresponds to an exterior of an automobile.

The chassis refers to a part of the vehicle excluding the body part, and the chassis frame corresponding to the skeleton of the vehicle is provided with all the devices necessary for driving such as an engine and can be driven only by the chassis.

On the other hand, small and medium-sized cars do not use the chassis frame, and are manufactured to give the body the strength (destructive strength, unbreakable property) and rigidity (the property that is not deformed when external force is applied). The form of mounting a power transmission device etc. may be used. In this way, if the body itself is manufactured to be durable and structured to withstand load or impact, the frame can be omitted, and the weight and floor can be lowered. To this end, the body is made in the shape of a box to distribute external forces throughout the body so that the force can be transmitted to the entire body. In addition, a small frame is coupled to a portion where external force is concentrated, such as a suspension device or an engine mounting portion, and the force is distributed to the body through the frame.

Here, if the body is divided into a front body and a rear body, the front body is attached to the engine, front wheel suspension, radiator, steering gear box and the like and has various rigidities. In addition, the impact of the shock and the protection of passengers in the interior when the collision is considered the most important point in the design. The rear body varies in shape depending on the shape of the sedan, hatchback and wagon.

Referring to the front side of the vehicle according to the prior art as follows.

As shown in FIG. 1, the front side part 1 includes a front apron assembly 2 disposed on both left and right sides of the vehicle body frame, a reinforcement panel 3 which is installed outwardly of the front apron assembly 2, and The outer panel 4a and the inner panel 4b may be coupled to each other by the side member 4 formed.

The reinforcement panel 3, the side member 4 is made of a thin plate.

On the other hand, the engine of the vehicle to obtain power by exploding gasoline and diesel, the engine is to form a multi-cylinder, that is, a plurality of cylinders in sequence and to install a piston therein to generate a sequential explosion force.

Of course, the explosion is in a certain order, for example, in the case of a four-cylinder engine in a certain order such as 1-4-2-3.

As described above, when the explosion is continuously performed, vibration is generated in the engine, and the vibration is transmitted to the body and is installed to block the ride comfort.

The engine mounting structure is located inside the engine room as shown in FIG. 2, and a mounting bracket 5 fixed to the top surface of the front apron assembly 2 and the side member 4, respectively, and the mounting bracket 5. It is mounted by the mounter 6 mounted on the upper surface, and the engine bracket 7 connecting the upper surface of the mounter 6 and the engine.

That is, the mounter 6 is configured to improve rigidity against vibration of the engine in a state where the mounter 6 is installed between the side member 4 and the engine bracket 7.

However, according to the structure of the conventional vehicle front body configured as described above, the front apron assembly 2, the reinforcement panel 3 and the front side member 4 are simply welded together, and the reinforcement panel 3, the front side member ( 4) is made of thin plate, so its rigidity is very weak, so it can't absorb shock during frontal and offset collision of the vehicle, causing deformation of the whole front part, and tire part invading the room, There is a threat.

And although the mounter 6 is made to reduce the vibration from an engine, since the said front apron assembly 2 which is a chamber shape consists of a thin plate, the rigidity which suppresses vibration is weak and the deformation amount is large, Deformation and vibration of the side member 4 is transmitted to the vehicle interior (dash panel, floor), thereby preventing the vibration transmitted from the engine, thereby causing a problem of booming sound (in the engine rpm3000 band).

The present invention has been made to solve the above problems, the front side of the vehicle that can promote the safety of the occupants by minimizing the intrusion into the passenger room by effectively absorbing the impact applied to the front of the vehicle in the event of a collision of the vehicle The purpose is to provide a secondary reinforcement structure.

Another object of the present invention is to absorb vibrations transmitted from an engine so as to improve in-vehicle occupancy and comfort.

In the front side reinforcement structure of the vehicle according to the present invention for achieving the above object, an apron assembly is disposed on the left and right sides of the front portion of the vehicle body frame, respectively, a reinforcement panel is installed inside the apron assembly, Side members are coupled to the inside of the reinforcement panel, and a space between the apron assembly and the reinforcement panel installed inside the apron assembly is provided with reinforcing partition walls which are respectively installed at predetermined intervals before and after a closed cross-sectional structure therebetween. Characterized in that formed a space.

An engine mounting bracket may be fixed to an upper portion of the reinforcing partition wall.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings. Prior to this, the terms or words used in the present specification and claims are defined in the technical spirit of the present invention on the basis of the principle that the inventor can appropriately define the concept of the term in order to explain his invention in the best way. It must be interpreted to mean meanings and concepts.

As shown in Figure 3, according to the front side reinforcement structure of the vehicle according to the present invention, the front apron assembly 10 is respectively installed on the left and right sides of the vehicle body frame, respectively, inside the front apron assembly 10 The reinforcement panel 20 is installed, and the inner side of the reinforcement panel 20, the outer member 31 and the inner panel 32 is formed with side members 30 are coupled to each other.

The reinforcement panel 20 may be bent and formed into a substantially depressed shape that is open toward the front apron assembly 10 to be welded to form a predetermined space between the front apron assembly 10.

In the space between the front apron assembly 10 and the reinforcement panel 20, reinforcement bulkheads 40 and 41 are respectively installed in the space between the front apron assembly 10 and the reinforcement panel 20 to form a closed cross-sectional structure. That is, between the front apron assembly 10 and the reinforcement panel 20 by the reinforcing partition walls 40 and 41 is a closed cross-sectional structure can be increased the stiffness to the external force.

On the other hand, as shown in Figure 4, the engine is located inside the engine compartment and fixed to the upper surface of the front apron assembly 10 (shown in FIG. 3) and the side member 30 (shown in FIG. 3), respectively. The mounting bracket 50 may be mounted by a mounting bracket 60 mounted on the upper surface of the bracket 50 and an engine bracket 70 connecting the upper surface of the mounter 60 to the engine.

The upper and lower ends of the reinforcing partition walls 40 and 41 are horizontally bent, respectively, and the upper and lower ends of the reinforcing partitions 20 are in close contact with the upper and lower horizontal parts of the reinforcing panel 20 and bolted to both ends of the mounting bracket 50. 42 can be fastened respectively.

The action of the front side reinforcement structure of the vehicle according to the present invention configured as described above is as follows.

When the front or offset collision of the vehicle, the apron assembly 10, the reinforcement panel 20 and the side member 30, which is the front side of the vehicle, the shock is transferred to them so that they are absorbed by the deformation.

At this time, the apron assembly 10, the reinforcement panel 20 and the reinforcement bulkheads (40, 41) to form a space of the closed cross-section itself between them to not only reduce the vibration because of the large stiffness to the external force By acting to improve the rigidity of the apron assembly 10, the apron assembly 10 is prevented from being vibrated, and is prevented from being pushed into the passenger compartment.

On the other hand, when the vibration of the engine is transmitted to the engine mounter 60 through the engine bracket 70 is transmitted to the side member 30 and the apron assembly 10.
