The vertical support part 285, the first side part 230, the second side part 235, and the side members 220 and 225 may be configured.

The first horizontal support part 250, the first side part 230, and the second side part 235 constitute a top frame of the carrier 150, and the second horizontal support part 240 is a bottom frame of the carrier 150. Can be configured.

The first vertical support part 280 and the second vertical support part 285 are horizontally spaced apart at predetermined intervals, and support the first horizontal support part 250 and the second horizontal support part 240 from the left side and the right side, The entire frame of the carrier 150 may be configured together with the first horizontal support 250 and the second horizontal support 240.

The first side part 230 and the second side part 235 are coupled to the left and right sides of the first horizontal support part 250, respectively, and serve to receive the head lamp 170.

The side members 220 and 225 may be firmly coupled to the first vertical support part 280 and the second vertical support part 285 at left and right sides so that the entire frame of the carrier 150 is mounted on the vehicle. The coupling may be made by a general coupling means such as bolting coupling, rivet coupling, welding coupling.

Meanwhile, in one embodiment of the present invention, the first horizontal support part 250 may be configured by combining the left horizontal support part 260 and the even flat support part 270.

The left horizontal support part 260 constitutes the left side of the first horizontal support part 250, and the even horizontal support part 270 constitutes the right side of the first horizontal support part 250. The left horizontal support 260 and the even horizontal support 270 are hinged at the center of the first horizontal support 250, respectively. Here, hinge coupling means coupling with a center point to enable rotation.

The left end of the left horizontal support 260 is coupled with the first vertical support 280, the side member 220 and / or the first side part 230, and the left end of the left horizontal support 260 is hinged. Can rotate around.

The right end of the even flat support 270 is coupled with the second vertical support 285, the side member 225 and / or the second side part 235, and the right end of the even flat support 270 is hinged. Can rotate around.

5A shows an exploded perspective view of the first horizontal support of FIG. 4, and FIG. 5B shows a perspective view of the assembled state of FIG. 5A.

5A and 5B, the first horizontal support part 250 includes a left horizontal support part 260 and an even flat support part 270. The left horizontal support part 260 and the even flat support part 270 are hinged to the side ends 267 and 277, respectively, and can rotate about the side ends 266 and 277, respectively.

Meanwhile, the left horizontal support part 260 and the even horizontal support part 270 may have a predetermined membrane structure. Here, the membrane structure refers to a structure in which a predetermined frame is formed by a predetermined partition 104 or rib structure between the upper plate 102 and the lower plate 103. The left horizontal support 260 and the even flat support 270 may each have a membrane structure to improve the tensile strength or the compressive strength corresponding to the external force. In addition, the membrane structure of the left horizontal support portion 260 and the even-flat support portion 270 can be relatively easily deformed due to the impact that is rapidly transmitted when the vehicle collides with the pedestrian, so it is applied to the pedestrian by the collision with the pedestrian. It can reduce the impact of losing.

In addition, the right end 265 of the left horizontal support 260 and the left end 275 of the even flat support 270 may be hinged or elastically coupled to each other. Alternatively, as shown in FIG. 5A, the right end 265 of the left horizontal support 260 and the left end 275 of the even flat support 270 may be coupled by a combination of hinge coupling and elastic coupling.

When the right end 265 of the left horizontal support 260 and the left end 275 of the even horizontal support 270 are hinged to each other, the end where the left horizontal support 260 and the even horizontal support 270 are coupled to each other. The part (that is, the center of the first horizontal support part 250) may be moved downward by a collision with a pedestrian. More specifically, since the left horizontal support 260 and the even horizontal support 270 are rotated around the left end 267 and the right end 277, respectively, the right end 265 and the superior of the left horizontal support 260. The left end 277 of the flat support 270 may be moved downward.

In addition, even when the right end 265 of the left horizontal support 260 and the left end 275 of the even horizontal support 270 are elastically coupled to each other, the left horizontal support 260 and the even horizontal support 270 are coupled to each other. The end portion (that is, the center of the first horizontal support portion 250) may be moved downward by a collision with a pedestrian. Herein, the elastic coupling forms a coil spring coupling ring at the right end 265 of the left horizontal support 260 and the left end 275 of the even flat support 270, respectively, and forms a coil spring 291 at the ring. By combining, the left horizontal support 260 and the even horizontal support 270 may be coupled to each other. As a result, the left horizontal support part 260 and the excellent flat support part 270 may be horizontal to each other when there is no external force, and when the collision with the pedestrian is performed, the buffering action may be performed by the elastic force.

In addition, an elastic body may be included in the left end 267 of the left horizontal support 260 and the right end 277 of the even flat support 270. For example, by mounting the coil springs 292 and 293 in the vertical state on the left end 267 of the left horizontal support 260 and the right end 277 of the even horizontal support 270, respectively, a sudden collision with a pedestrian. When the coil springs 292 and 293 of the left horizontal support 260 or the even horizontal support 270 are compressed, the left horizontal support 260 or the even horizontal support 270 is slid downward so that the first horizontal support 250 is slid downward. Shock can be absorbed.

As described above, in the embodiment of the present invention, the first horizontal support part 250 is divided into a left horizontal support part 260 and an even flat support part 270, and the first horizontal support part suddenly collides with the first horizontal part. The right end 265 of the left horizontal support 260 and the left end 275 of the superior flat support 270 located in the center of the support part 250 move downward to mitigate an impact applied to the pedestrian. have. In addition, an elastic body may also be mounted on the left end 267 of the left horizontal support 260 and the right end 277 of the even flat support 270 to alleviate the overall impact of the collision with the pedestrian.

Meanwhile, in one embodiment of the present invention, the cooling module 110 may be moved in the rear or lower direction of the vehicle in association with the movement of the first horizontal support part 250. For example, when the first horizontal support part 250 and the cooling module 110 are coupled to each other, and the first horizontal support part 250 rapidly moves downward due to a collision with a pedestrian, the cooling module is interlocked with this. 110 may also be moved. In other words, the first horizontal support part 250 and the cooling module 110 may be flexibly coupled, and the cooling module 110 may move in association with the movement of the first horizontal support part 250.

As an example of coupling the first horizontal support 250 and the cooling module 110, an annular hook is formed on the rear surface of the left horizontal support 260 and the even flat support 270 of the first horizontal support 250. can do. Thus, the first horizontal support 250 and the cooling module 110 may be coupled to each other by forming a through hole for allowing the hook to be coupled through the upper end of the cooling module 110. Accordingly, the cooling module () may be moved in cooperation with the left horizontal support portion 260 and the even horizontal support portion 270 of the first horizontal support portion 250.

As another example of coupling the first horizontal support 250 and the cooling module 110, the cooling module 110 is formed by an elastic body on the first horizontal support 260 and the second horizontal support 270 of the carrier 150. And the first horizontal support part 250. Accordingly, when the left horizontal support part 260 and the even horizontal support part 270 of the first horizontal support part 250 are moved by the pedestrian in the event of a collision between the vehicle and the pedestrian, the cooling module 110 is caused by the elastic force. Also move in conjunction with, or may act as a shock absorber to mitigate the impact by the elastic force.

As another example of moving the cooling module 110 in a rearward or downward direction of the vehicle in association with the movement of the first horizontal support part 250, a predetermined actuator (not shown) for moving the cooling module 110 may include a carrier 150. ) Or the vehicle body. Accordingly, when the collision between the vehicle and the pedestrian is detected, an actuator (not shown) may be driven to retreat the position of the cooling module 110 to the rear of the vehicle. As a result, the cooling module 110 is moved in advance to the position where the left horizontal support part 260 and the even horizontal support part 270 of the first horizontal support part 250 move, thereby alleviating the impact of the vehicle and the pedestrian due to the collision with the pedestrian. You can.

As described above, in one embodiment of the present invention by moving the cooling module 110 in conjunction with the first horizontal support portion 250 of the carrier 150, the impact of the vehicle and the pedestrian due to the collision with the pedestrian is relatively effective.
