Description

Left support of automobile front support

Technical Field

The utility model belongs to the technical field of automobile part manufacturing, and particularly relates to a left support of an automobile front support.

Background

First, the automobile referred to in the present specification should be understood in a broad sense, and includes a four-wheel or more fuel-powered vehicle and an electric vehicle. The left side support of the front bracket of the automobile, which is the name of the present utility model, refers to one of two side members that connect the front bracket of the automobile with the front bumper support cross member, that is, a side member located on the left side (in front of the driver seat) of the two side members. Correspondingly, the right side member (front side of the front passenger seat) of the two side members is called a right support of the front bracket of the automobile.

The right support of the automobile front support and the left support of the automobile front support, which are provided by the applicant for the customer, are made of manganese steel, and the right support of the automobile front support and the left support of the automobile front support are not different in shape and structure except for different installation positions. Under the same size condition, the automobile front support (left or right) made of the full manganese steel has higher strength, and the anti-collision capability of an automobile can be effectively improved under the cooperation of the front bumper supporting cross beam and other protective pieces. However, the support of the front bracket (left or right) of the automobile made of the all-manganese steel has the defect of larger weight.

In general, in the case where a front collision is about to occur at the front end of a vehicle, a driver takes evasion measures based on the instinct of protecting the life safety of the driver, so that the probability of the front collision of the front vehicle body of the driver's seat directly with other vehicles or foreign objects is relatively low (this means that the left support of the front bracket of the automobile is more subjected to a lateral or oblique shearing force, and of course there is a frontal impact force, but usually a lateral or oblique shearing force), while the probability of the front collision of the front vehicle body of the front passenger seat directly with other vehicles or foreign objects is relatively high (this means that the right support of the front bracket of the automobile is more subjected to a frontal impact force, and of course there is a lateral or oblique shearing force, but usually a frontal impact force is mainly), and therefore, when designing the front support of the front bracket of the automobile, it is necessary to distinguish the right support of the front bracket of the automobile from the left support of the front bracket of the automobile. The patent application of the utility model aims at the left support of the front support of the automobile, and the applicant provides an utility model patent application additionally for the right support of the front support of the automobile.

Disclosure of Invention

The utility model aims to overcome the technical defects that the right support weight of an automobile front support made of full manganese steel provided by the applicant is too heavy, the weight reduction of the automobile is not facilitated, and the structural design of the automobile front support is not fully considered with the stress characteristics of the left support, and the utility model is realized by the following technical scheme:

the utility model provides a left side of car fore-stock supports, is including the cylindric shell body that the material is manganese steel, cup joints in cylindric shell body, the cylindric inner shell body that the material is carbon fiber in cylindric shell body, is provided with cylindric elastic material body in cylindric inner shell body, is provided with preceding turn-ups and preceding deep floor at the front end of cylindric shell body, is provided with back turn-ups and back deep floor at the tail end of cylindric shell body, and the contact surface of cylindric shell body and cylindric inner shell body passes through glue to be connected fixedly.

On the basis of the technical scheme, the utility model can be additionally provided with the following technical means:

the number of the front reinforcing rib plates is 3, and the angle of the central angle corresponding to the arc surface between two adjacent front reinforcing rib plates is 120 degrees.

Further, the number of the rear reinforcing rib plates is 3, and the angle of the central angle corresponding to the arc surface between two adjacent rear reinforcing rib plates is 120 degrees.

Further, the side surfaces of the front reinforcing rib plate and the rear reinforcing rib plate are isosceles right triangles.

Further, screw holes are formed in the front flanging and the rear flanging.

The utility model has the main beneficial effects as follows:

the automobile front support can effectively absorb energy generated when collision occurs, reduce injury to passengers of a passenger seat caused by collision, and has the weight smaller than that of an automobile front support made of all-manganese steel produced by the applicant before.
