Description

An automobile front upper component assembly structure

technical field

The invention relates to an automobile body, in particular to an automobile front upper component assembly structure.

Background technique

The front upper component assembly of the automobile is mainly used to install the automobile parts such as the front bumper, the front hood lock and the radiator. It connects the left and right radiator strut assemblies through bolts, which not only meets the design requirements of the gap between the nacelle cover and the front bumper, but also meets the performance indicators such as the yaw mode and torsional stiffness of the nacelle. For example, CN208813314U discloses "a front upper member assembly bracket and automobile" to solve the problem of torsion of the front upper member assembly in the prior art that the displacement of the front bumper is too large. The front upper component assembly bracket includes: a front cover lock mounting piece, the front cover lock mounting piece has a first connection hole and a first installation hole for connecting with the front cover lock on the front upper component assembly; plate, the fixing plate has a second connection hole and a second installation hole for fixed connection with the front crash beam assembly; the front upper member is connected between the front cowl lock installation piece and the fixing piece. A support plate is formed, one end of the support plate of the front upper member assembly is bolted to the front cover lock mounting part through the first connection hole, and the other end is bolted to the fixing plate through the second connection hole.

However, with the increasing importance of intelligent technology in the automotive industry, it is of great significance to improve the quality of the whole vehicle and increase the attention as the through-type headlights with a strong sense of technology are launched on the market for new vehicles. For example, CN206449548U discloses "a novel array type light guide structure for automobile headlights", which includes a main body and several light guide strips penetrating through the main body, the light guide strips are distributed in an array, and each light guide strip has an independent light guide strip. A light port and a light outlet, the light inlet port of the light guide strip is provided with LED lights, and the LED lights are in one-to-one correspondence with the light guide strip. It adopts a light guide structure made of silica gel, which has better light transmission and lighter weight; it can achieve a matrix-type lighting effect, which is more fashionable and dynamic; by controlling the on and off of a single LED, it can realize a variety of light types, which can be integrated. The functions of far and near light are integrated into one.

CN203581148U discloses "a connection structure of a front upper member welding assembly and a vehicle frame", comprising a front upper member welding assembly and a vehicle frame, and the front upper member welding assembly includes a front upper member beam assembly, and the lower ends are respectively connected to the front upper member. Two fenders and headlight brackets that are fixedly connected at the left and right ends of the member beam assembly, and two front upper member uprights whose upper ends are respectively fixedly connected to the left and right ends of the front upper member beam assembly, two front upper member uprights The lower ends of the frame are respectively fixedly connected with the front ends of the left and right longitudinal beams of the vehicle frame through the front upper member connecting pieces. It can improve the positional accuracy after the welding assembly of the front upper member and the frame are assembled. However, it does not involve how to adapt to the installation of the new array type automobile headlights. Therefore, it is necessary to develop a front upper member assembly for installing the through-type headlights.

Further, the rear end of the front protection right installation bracket is fixedly connected with the right part in front of the front upper member body, and the lower part of the front part of the front protection right installation bracket is fixedly connected with the upper surface of the right part of the middle beam; the The rear end of the front protection left mounting bracket is fixedly connected with the left part of the front of the front upper member body, and the lower part of the front part of the front protection left installation bracket is fixedly connected with the upper surface of the left part of the middle beam.

Further, an anti-falling bracket in the shape of "┓" is fixedly connected to the upper part of the middle beam support; a positioning pin is arranged at the lower part of the middle beam support.

The present invention has the following beneficial effects:

Since the right mounting bracket and the left mounting bracket for installing the through-type headlights are provided, the through-type headlights can be connected and fixed through the right mounting bracket and the left mounting bracket;

Because the middle part of the front lower side of the front upper member body is provided with a connecting plate, and the connecting plate, the front protection right mounting bracket and the front protection left mounting bracket are connected to the front upper member body and the middle beam at the same time, it not only increases the through-type front transverse beam The strength and stiffness of the lamp mounting points, while also increasing the strength and stiffness of the front bumper mounting points;

Since the installation points of the through-type front cross-light and the front bumper are welded on the middle beam, the relative matching gap between the through-type front cross-light and the front bumper is guaranteed to be consistent;

Because the middle beam support is provided, it is connected to the front collision beam through the welding positioning pin at the lower end, so as to not only support the Z-direction of the through-type front beam, but also provide a Z-direction support for the front bumper, which can prevent the penetration of the front bumper. The front cross lights and the front bumper drop down;

Since the height of the Z-direction mounting point of the through-type front cross-lights and the front bumper can be adjusted through the welding positioning pins supported by the middle beam, the height difference between the through-type front cross-lights and the headlights can be ensured.
