Description

  The present invention relates to a structure of a resin front end portion in a vehicle.

  Conventionally, front side members on both the left and right sides extending in the longitudinal direction of the vehicle, support members with a frame structure, engine assemblies, bumper members, etc. are arranged in the front part of the vehicle, and heat exchange of radiators, condensers, etc. The vessel is suspended from the upper and lower portions of the support member (see, for example, Patent Document 1). The support member having such a frame structure is composed of a sheet metal member having a rigid skeleton, and is capable of withstanding the suspension load of a heat exchanger such as a heavy radiator and maintaining the mounting accuracy of a headlamp and the like. Plays.

By the way, in recent years, in order to reduce the weight and increase the functionality, a resin front end portion manufactured using a resin material tends to be employed instead of the support member having a sheet metal structure. Such a resin front end portion has a rectangular frame structure having an upper member portion, left and right side brace portions, and a lower member portion in order to ensure the same rigid performance and component mounting performance as a support member having a sheet metal structure. It is configured. The left and right side brace portions are suspended from the front end portion of the front side member, and the upper and lower portions of the heat exchanger are suspended from the resin front end portion.
Also, in order to improve production efficiency in conventional vehicles, heat exchangers such as radiators, condensers, and intercoolers, and resin front end parts are integrated as an assembly together with engine assemblies such as engines, transmissions, and engine accessories. In the production process, it is lifted from below in the production process and assembled to the vehicle body, and is collectively mounted on the vehicle body skeleton.

  However, since the resin front end portion having the conventional structure described above tends to be less rigid than the support member having the sheet metal structure, it is necessary to ensure rigidity by forming a large cross-sectional area of the resin front end portion. was there. However, when the cross-sectional area of the resin front end portion is increased to ensure rigidity, the outer end portion of the structure protrudes to the outside of the vehicle by that amount, such as a headlamp installed outside the structure. Peripheral parts had to be laid out on the outside of the vehicle, which could increase the size of the vehicle.

  On the other hand, in a particularly compact vehicle, the structure for suspending the heat exchanger is not large, and it is required that the space in the front of the vehicle can be used in the same way as the support member of the sheet metal structure. It was not appropriate to use the part for the suspension structure of the heat exchanger. Also, in the case of a compact vehicle, the engine room is small, and if the assembly of the resin front end, engine assembly and heat exchanger is lifted from below the vehicle body, it will approach the peripheral parts such as the front side member and the dash panel. Therefore, it is necessary not to simply lift the assembly upward, but to lift it while tilting or rotating it to avoid interference with surrounding parts, especially where the clearance with the surrounding parts is narrow or where you do not want to interfere. In this case, it is necessary to lift the assembly upward while restricting the position of the assembly using a guide device, and the assembly work is troublesome.

  The present invention has been made in view of such a situation, and the purpose thereof is to avoid interference with peripheral parts by forming a guide portion by utilizing the characteristics of a resin material having a degree of freedom in shape. In addition, while reducing the weight and securing rigidity of the resin front end, the assembly of the resin front end, engine assembly, and heat exchanger assembly in the production process is quickly and reliably performed to reduce production costs. Another object of the present invention is to provide a resin front end structure that can improve the fuel efficiency of a vehicle.
