Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0136096, filed on October 12, 2023, which is incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a vehicle front structure. Background Art

[0004] Vehicles are tested to evaluate crashworthiness through various tests such as frontal impact tests, side impact tests, rear impact tests, and rollover tests. Recently, the Insurance Institute for Highway Safety (IIHS) introduced a small overlap impact test (simulating a small overlap frontal impact with a rigid barrier). As the most stringent of the known impact tests, this small overlap impact test is conducted by allowing a small portion of the vehicle (25% of the vehicle width in front of the driver's seat) traveling at a speed of 40MPH (64KPH) to hit the barrier.

[0005] As the weight of the high-voltage battery, the weight and size of the power electronics (PE) module, etc. in the electric vehicle increases, the collision energy may increase, and accordingly, the weight of the reinforcement structure of the vehicle body may increase, which may increase the cost, packaging, etc. of the vehicle.

[0006] In the event of a small overlap collision, the reaction force generated by the vehicle may be very large, and the degree of damage to the vehicle and the degree of injury to the passengers may be very high. However, electric vehicles according to the prior art are designed to protect the passenger compartment and the high-voltage battery, so it may be difficult to effectively displace the vehicle laterally in the event of a small overlap collision. In particular, as the weight of the high-voltage battery, the weight and size of the PE module, etc. in the electric vehicle increase, it may be difficult to displace the vehicle laterally in the event of a small overlap collision.

[0007] The above information described in this Background section may include information that is not considered to be prior art that is already known. Utility Model Content

[0097] The front edge of the first front module 51 may be fixed to the top surface of the first cross member 21 using fasteners, welding, etc., and the rear edge of the first front module 51 may be fixed to the top surface of the second cross member 22 using fasteners, welding, etc.

[0098] The front edge of the second front module 52 may be fixed to the top surface of the first cross member 21 using fasteners, welding, etc., and the rear edge of the second front module 52 may be fixed to the top surface of the middle cross member 24 using fasteners, welding, etc.

[0099] The front edge of the third front module 53 may be fixed to the top surface of the middle cross member 24 by fasteners, welding, etc., and the rear edge of the third front module 53 may be fixed to the top surface of the second cross member 22 by fasteners, welding, etc. In addition, the bottom surface of the third front module 53 may be fixed to the top surface of the additional longitudinal member 25 by fasteners, welding, etc., so that the bottom surface of the third front module 53 may be firmly supported by the additional longitudinal member 25.

[0100] Reference Figure 2 When the obstacle 6 collides with the right bumper beam extension 14 of the front bumper beam 13 in a small overlap collision, the deflector 15 of the right bumper beam extension 14 hits the right front side member 11, and the collision load may be first transmitted along the transverse load path L1 defined by the first cross member 21. After a selected, set or predetermined time period has passed, the collision load may be secondarily transmitted along the transverse load path L2 defined by the second cross member 22. The collision load may be first transmitted between the front portions of the pair of front side members 11 by the first cross member 21, and then secondarily transmitted between the rear portions of the pair of front side members 11 by the second cross member 22, and therefore, the load transmission through the second cross member 22 may be relatively delayed compared to the load transmission through the first cross member 22. In addition, the collision load can be transmitted between the first cross member 21 and the second cross member 22 in the longitudinal direction of the vehicle along the longitudinal load path L3 defined by the longitudinal member 23, between the longitudinal member 23 and the front side member 11 in the width direction of the vehicle along the transverse load path L4 defined by the intermediate cross member 24, and between the intermediate cross member 25 and the second cross member 22 in the longitudinal direction of the vehicle along the longitudinal load path L5 defined by the additional longitudinal member 25, so that the time interval between the load transmission through the first cross member 21 and the load transmission through the second cross member 22 can be reduced. Since the collision load can be quickly transmitted in the width direction of the vehicle, the lateral displacement of the vehicle can be effectively and quickly achieved. Since the lateral displacement of the vehicle is effectively and quickly achieved in the case of a small overlap collision, the overlap amount between the obstacle 6 and the vehicle can be significantly reduced.

[0101] Reference Figure 3The vehicle front structure 10 according to the exemplary embodiment of the present disclosure may include a front subframe 60 located below the pair of front side members 11. The front subframe 60 may include: a pair of lower reinforcements 65; a pair of front mounting members 61 mounted on the front portions of the pair of front side members 11; and a pair of rear mounting members 62 mounted on the rear portions of the pair of front side members 11.

[0102] Each lower reinforcement 65 may extend from a front end of the front subframe 60 toward the front of the vehicle.

[0103] Each front mount 61 may protrude from the front of the front subframe 60 toward the corresponding front side member 11 and may be mounted on the front of the corresponding front side member 11 by mounting hardware. The first cross member 21 may be aligned with the front mount 61 in the vertical direction.

[0104] Each rear mounting piece 62 may protrude from the rear of the front subframe 60 toward the corresponding front side member 11 and may be mounted on the rear of the corresponding front side member 11 by mounting hardware. The second cross member 22 may be aligned with the rear mounting piece 62 in the vertical direction.

[0105] In the event of a frontal collision / impact or a small overlap collision, the collision load can be transferred to the front subframe 60 through the lower reinforcement 65. Since the first cross member 21 is vertically aligned with the front mounting member 61, the collision load transferred to the front subframe 60 can be quickly transferred to the first cross member 21 through the front mounting member 61, and since the second cross member 22 is vertically aligned with the rear mounting member 62, the collision load transferred to the front subframe 60 can be quickly transferred to the second cross member 22 through the rear mounting member 62. Therefore, the collision load can be quickly transferred to the first cross member 21 and the second cross member 22 through the front subframe 60, so that the lateral displacement of the vehicle can be quickly and effectively achieved.

[0106] As described above, the vehicle front structure according to the example embodiment of the present disclosure can be designed to use multiple cross members provided at the front of the vehicle body and multiple front modules mounted on the multiple cross members as load paths, thereby effectively causing the vehicle to be laterally displaced in the event of a small overlap collision.

[0107] Although the present disclosure has been described above with reference to example embodiments and the accompanying drawings, the present disclosure is not necessarily limited thereto, but various modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the present disclosure as claimed in the claims.
