front body structure

Abstract

The invention relates to the vehicle field, and discloses a vehicle body front structure comprising a front crashproof beam, a longitudinal beam front section, a front subframe, a water tank upper crossbeam, a water tank lower crossbeam, and water tank columns; the front end of the water tank column is connected with the front crashproof beam; the rear end of the water tank column is connected with the longitudinal beam front section through a first connecting plate; the front subframe is provided with a second connecting plate; a first X-direction mounting hole is arranged on the bottom of the first connecting plate; a position, opposite to the first X-direction mounting hole, on the top of the second connecting plate is provided with a second X-direction mounting hole; the first and second connecting plates are fixedly connected by using a fastener to penetrate the first and second X-direction mounting holes; an existing front subframe complex Z-direction mounting structure is converted into the simpler X-direction mounting structure, thus greatly simplifying the structure, improving space utilization rate, mitigating vehicle body front portion weight, and further improving longitudinal beam front section direct impact energy-absorbing effect.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle body front structure. Background technique [0002] The front structure of the car body generally includes the front anti-collision beam, the front sub-frame, the upper beam of the water tank, the lower beam of the water tank, the installation bracket of the hood strut, the installation bracket of the headlights and the front structure of the longitudinal beam, connecting the upper beam and the lower beam of the water tank The headlight mounting bracket is set on the top of the column, and the front of the car body needs to install multiple components such as the engine. The space is limited, and the structure of the front of the car body needs to be reasonably arranged; The front impact performance has higher requirements. [0003] In the existing front structure of automobile body, in order to facilitate installation, the front sub-frame is installed under the front longitudi...

AI Technical Summary

Problems solved by technology

[0004] The present invention is completed based on the deficiencies of the above-mentioned prior art, and its primary technical problem is to improve the complex structure, heavy weight, and small space utilization rate caused by the Z-direction installation of the front sub-frame, which further affects the The problem of frontal impact energy absorption effect of front longitudinal beam
