A car body front frame

Abstract

The invention discloses an automobile body front end frame which comprises an upper crossbeam. A left front longitudinal beam and a right front longitudinal beam are symmetrically arranged at the lower end of the upper crossbeam. An intermediate crossbeam is fixed between the left front longitudinal beam and the right front longitudinal beam. Water tank supports are fixed between the intermediatecrossbeam and a lower crossbeam. The position of a water tank is fixed through water tank fixed supports. Water tank movable supports are installed on the periphery of the water tank through springs.When a collision happens, impact force of the left side and the right side is effectively buffered through sliding of the water tank movable supports and elastic connection of the springs and cannot directly act on the water tank, and the impact on the water tank is attenuated. An engine hood lock frame is fixed between the upper crossbeam and the intermediate crossbeam and reinforced and fixed through buffering supports. Meanwhile, when an engine hood is closed, direct impact conducted by the engine hood to the engine hood lock frame can be effectively buffered through hydraulic buffers on the buffering supports, and the engine hood lock frame is prevented from deforming due to the impact.

Description

technical field [0001] The invention relates to the technical field of automobile body frame design, in particular to a front frame of an automobile body. Background technique [0002] The front-end frame of the car body is mainly used to fix functional accessories such as front-end exterior parts, radiators, and hood lock brackets. Among them, due to the large mass of the radiator, the front-end frame is subjected to a large force and moment when the car is running, which requires the front-end frame to have good strength and torsional rigidity. In the prior art, the front end of the car is generally provided with a water tank frame, which is an important part of the body-in-white. The existing car water tank frame is usually a non-closed structure composed of several sheet metal parts welded. The cushioning effect in the middle is not good. In addition, the bonnet lock frame should also be installed on the front frame of the car. When the car hood is closed, the impact fo...

In the prior art, the front end of the car is generally provided with a water tank frame, which is an important part of the body-in-white. The existing car water tank frame is usually a non-closed structure composed of several sheet metal parts welded. The cushioning effect in the middle is not good. In addition, the bonnet lock frame should also be installed on the front frame of the car. When the car hood is closed, the impact force on the hood lock frame is very large, which requires the hood lock frame to have a good Strength, to prevent deformation due to the collision of the hood, for this purpose, we provide a car body front frame
