[0003] This invention relates to a vehicle body. Background Technology

[0004] Recently, the automotive industry has introduced new concepts and visions for the future of mobility, aiming to realize a dynamic, human-centered future city. One of these future modes of mobility is the purpose-based personal vehicle (PBV).

[0005] PBV is an environmentally friendly mobility solution that provides passengers with the customized services they need during the journey from origin to destination, and can use electric vehicle-based artificial intelligence to perform optimal route planning and cluster driving for each situation.

[0006] For example, PBV is a box-type vehicle with a large interior space, and the windshield is positioned at the front of the vehicle to provide a large interior space.

[0007] The PBV's body comprises a lower body and an upper body. The lower body is also known in the industry as a rolling chassis or skateboard chassis, and the upper body is mounted on the lower body. Here, the battery pack is mounted on the lower body. Furthermore, the upper body can be a space frame formed by welding steel plates or tubing.

[0008] However, the problem with this type of PBV is that due to the boxy design of the front body, the front frame may be weaker, and its impact absorption performance in the event of a frontal collision may be weaker.

[0009] The information disclosed in this background section is only intended to enhance the understanding of the background technology of the present invention, and therefore, this information may contain information that does not constitute prior art known to those skilled in the art.

[0019] The cover transverse bar assembly may also include a spacer member that engages with the upper member of the protective plate and the reinforcing member between the upper member of the protective plate and the reinforcing member.

[0020] The cover transverse bar assembly may also include a cover transverse bar extension that is connected to the floor reinforcement frame and coupled to a pair of cover transverse bars.

[0021] A pair of transverse bars can include closed sections of different shapes.

[0022] The reinforcing member can be connected to the body mounting support and the wheel cover of the upper body, which is connected to the front member.

[0143] Hereinafter, the effects of the front vehicle body structure 100 configured according to an exemplary embodiment of the present invention as described above will be described in detail with reference to the above-disclosed description and drawings.

[0144] According to an exemplary embodiment of the present invention, the front body structure 100 includes a cover support unit 40 for supporting a front cover 30 located at the front of the upper body 20.

[0145] The cover support unit 40 is connected to the front cover 30 via the front side member 21 and the front column 23 of the upper body 20 and supports the front structure of the front cover 30.

[0146] The cover support unit 40 includes a lower cover transverse member 41, a lower cover support member 43, an upper cover support member 45, a lower cover support member 47, an upper protective plate member 49, and a cover transverse rod assembly 61.

[0147] Figure 10 This is a view used to illustrate the effect of the front vehicle body structure according to an exemplary embodiment of the present invention.

[0148] Reference Figure 10 The function of the cover support unit 40 is explained in detail. In an exemplary embodiment of the present invention, the road load can be transferred to the front member 21 and a lower load channel 101 is formed. Through the lower load channel, the road load is transferred to the front pillar 23 through the upper member 49 of the protective plate.

[0149] Reference Figures 5 to 10 The load input to the floor reinforcement frame 53 is transmitted to the front column 23 through the cover transverse bar assembly 61 and the cover underside support 47 to form the upper load channel 103.

[0150] In addition, refer to Figure 10 A top load channel 105 is formed, in which the load input to the lower lateral member 41 and the lower support member 43 is transmitted to the front column 23 through the upper support member 45.

[0151] Therefore, in an exemplary embodiment of the present invention, the vehicle body can be provided with strength in the longitudinal direction, the vehicle width direction, and the vertical direction between the front cover 30, the cover support unit 40, and the lower body 10, and torsional strength can also be improved.

[0152] Meanwhile, in an exemplary embodiment of the present invention, a first mounting point 81 is formed on the front member 21, connecting to the lower cover transverse member 41 and the lower cover support member 43. Furthermore, in an exemplary embodiment of the present invention, a first mounting portion 87 engaging with the first mounting point 81 is formed in the front energy-absorbing box 16 located in the front crossbeam assembly 14 of the lower body 10.

[0153] Furthermore, in an exemplary embodiment of the present invention, the front member 21 is provided with a body mounting support 64 connected to the wheel arch 27 and a second mounting point 91 connected to the upper member 49 of the protective plate and the hood transverse bar assembly 61. Additionally, in an exemplary embodiment of the present invention, a second mounting portion 97 (where the second mounting point 91 engages) is formed on the front chassis frame 11 of the lower body 10.

[0154] Therefore, in an exemplary embodiment of the present invention, the connection strength of the first mounting portion 87 connected to the first mounting point 81 may be less than the connection strength of the second mounting portion 97 connected to the second mounting point 91.

[0155] Therefore, in an exemplary embodiment of the present invention, when a vehicle is involved in a frontal collision, deformation first occurs in the first mounting portion 87 due to the collision load, and deformation may not occur in the second mounting portion 97.

[0156] Therefore, in an exemplary embodiment of the present invention, the frontal impact performance of a vehicle can be improved by absorbing and distributing the impact load generated by the first mounting portion 87 and the second mounting portion 97 due to the frontal impact of the vehicle.

[0157] Although the invention has been described in conjunction with exemplary embodiments that are now considered practical, it should be understood that the invention is not limited to the disclosed embodiments. Rather, the invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
