This vehicle body front structure includes a front side frame (14) which extends in a forward and rearward direction of a vehicle body, and a side wall member (52) which is provided outside the front side frame (14) in a vehicle width direction and joined to the front side frame (14), wherein the front side frame (14) has at least three folding portions, which include a first folding portion (24), a second folding portion (25), and a third folding portion (26) capable of being bent by an impact load (F1, F3) input from in front of a vehicle, in this order at intervals from a front toward a rear of the vehicle body, and has a reinforcing panel (65) which is provided between the second folding portion (25) and the third folding portion (26) among the side wall members (52), is stacked on a compression portion (81) on which a compressive force (F2, F4) acts from the impact load (F1, F3), and has a vertical bead (87).

A head-up display device includes a casing provided inside an instrument panel and provided with a concave mirror configured to project image information emitted from a light source onto a front windshield glass. In the head-up display device, a retraction portion is provided on a lower side of the concave mirror in a vehicle up-down direction and configured to allow the concave mirror to move downward in the vehicle up-down direction when an impact load is input to the concave mirror from an upper side in the vehicle up-down direction.

A vehicle front structure having an upper member joined to a damper base and being capable of absorbing a larger load when a vehicle is in full-lap collision or offset collision and comprises a pair of left and right upper members disposed respectively on left and right sides of the vehicle a pair of left and right damper bases in each of which a damper is fitted, wherein each of the upper members includes a main upper member portion having a cross section in a rectangular shape that is perpendicular to an axis thereof, the left and right damper bases are joined respectively to the left and right upper members at upper portions of the main upper member portions, and each of the main upper member portions includes a lower portion having a pair of indented portions formed at both corner portions in a vehicle width direction of the lower portion of and a step portion formed to extend in the vehicle width direction and connect the pair of the indented portions.

A vehicle body assembly structure includes a floor assembly including a floor, a front coupling portion provided at a front of the floor, and a rear coupling portion provided at a rear of the floor, and an upper assembly including a roof frame, a front mounting portion matched to the front coupling portion at a front of the roof frame, and a rear mounting portion matched to the rear coupling portion at a rear of the roof frame, wherein each of the front coupling portion and the front mounting portion and the rear coupling portion and the rear mounting portion are connected in a slide coupling structure.

A cowl louver is placed below a cowl top which is an outer plate member on an upper surface of a front part of a vehicle body. The cowl louver has a vertical wall which extends vertically from a cowl panel toward an expected direction of a load F. The vertical wall is bent at one location between an upper edge and a lower edge, and a length from a ridgeline at the bent position to the upper edge (upper width), and a length from the ridgeline to the lower edge (lower width), differ from each other. During deformation of the vertical wall due to collision, the bent portion moves on the vertical wall 40 so that energy is continuously consumed and the shock is absorbed.

The disclosure relates to the technical field of vehicles, and in particular provides a vehicle and a cowl top assembly thereof, which are intended to solve the problems of long development cycle, high cost and even proneness to false detonation in the solution in which existing vehicles use active-ejecting bonnet technology to reduce injuries to pedestrians in collision accidents. To this end, the cowl top assembly of the disclosure comprises a rear panel and a front panel structure, wherein the front panel structure comprises a first top panel, a first vertical panel, and a first bottom panel, and wherein a front edge of the first top panel and a front edge of the first bottom panel are respectively connected to an upper edge and a lower edge of the first vertical panel, and a rear edge of the first top panel and a rear edge of the first bottom panel are connected to the rear panel, so that a cavity is enclosed by the rear panel and the front panel structure; and first collapsing holes are formed in the first top panel, and second collapsing holes are formed in the first vertical panel. With this arrangement, injuries to pedestrians in pedestrian-vehicle collision accidents are reduced, less material is used, and lighter weight, shorter development cycle and lower cost are achieved.

An embodiment front vehicle body structure includes an underbody, an upper body coupled to the underbody, a front cowl disposed in front of the upper body, and a cowl support unit connected to the front cowl through a front pillar and a front side member of the upper body. An embodiment cowl support unit includes a cowl lower cross member connected to a front of the front side member along a vehicle width direction, a cowl lower support connected to the cowl lower cross member and the front cowl, and a cowl upper side support connecting an upper portion of the front pillar and the front cowl.
