Technical Field
The invention relates to the technical field of automobile parts, in particular to a vehicle body framework of a sealed SNS composite structure.
Background
The automobile body product is an automobile body framework carrier which is realized by connecting thousands of stamping sheet metal parts through welding, riveting, bonding, bolts and other connecting processes, and is realized through a coating and spraying process. The performance requirements of automotive bodies require not only aesthetic, novelty, but also strength to withstand external impacts. SNS (Safe & NVH Solutions) is a composite structure formed by adhering a composite material framework and a thermal expansion structure viscose glue to the cross section of a cavity of a vehicle body, and is a technology for improving the NVH performance of the whole vehicle from the passive noise reduction angle, and the weight of the vehicle body can be reduced on the premise of improving the rigidity mode, collision safety and durability of the vehicle body.
Disclosure of Invention
The invention aims to solve the technical problem of providing a vehicle body framework with a sealed SNS composite structure, which has a simple structure and is convenient to manufacture and install, and can improve the strength of the vehicle body against external impact and reduce the weight of the vehicle body.
The invention is realized by the following technical scheme:
the utility model provides a canned type SNS composite construction's automobile body skeleton, its includes SNS skeleton body and sealing ring skeleton, this internal fixed reinforcing plate and the epoxy foam who is equipped with a plurality of vertically and horizontally staggered of SNS skeleton glue the injection chamber, and this end of body of SNS skeleton is equipped with SNS skeleton body buckle, the sealing ring skeleton passes through SNS skeleton body buckle and SNS skeleton body fixed connection, the epoxy foam glues the injection chamber and is equipped with the mouth of moulding plastics towards the outside, and the epoxy foam is moulded plastics in the injection chamber and is had epoxy foam, be equipped with annular seal groove on the sealing ring skeleton, the sealing ring is installed in seal groove department.
Optimally, the SNS framework body, the reinforcing plate and the epoxy foaming glue injection cavity are integrally formed in an injection molding mode.
Furthermore, the sealing ring framework is integrally formed with a sealing ring framework buckle.
Advantageous effects of the invention
The invention protects a vehicle body framework with a sealed SNS composite structure, and has the following advantages:
1. the structure is simple and the weight is light;
2. the manufacture and the installation are convenient and quick;
3. the impact resistance is high, and the rigidity mode, the collision safety and the durability of the vehicle body are strong.
Drawings
FIG. 1 is a schematic view of the assembly structure of the present invention;
FIG. 2 is a schematic view of a vehicle body frame construction;
in the figure, the SNS frame comprises an SNS frame body, 2 rubber holes, 3 vehicle body metal plates, 4 SNS frame body buckles, 5 sealing ring frames, 6 sealing ring frame buckles, 7 annular sealing grooves, 8 reinforcing plates, 9 cavities, 10 epoxy foam injection cavities and 11 sealing rings.
Detailed Description
The utility model provides a canned type SNS composite construction's automobile body skeleton, its includes SNS skeleton body 1 and sealing ring skeleton 5, this internal integrated into one piece of SNS skeleton has a plurality of vertically and horizontally staggered's reinforcing plate 8 and epoxy foam injection molding chamber 10, and this end of body of SNS skeleton is equipped with SNS skeleton body buckle 4, the sealing ring skeleton passes through SNS skeleton body buckle and SNS skeleton body fixed connection, epoxy foam injection molding chamber is equipped with the mouth of moulding plastics towards the outside, and epoxy foam injection molding intracavity is moulded epoxy foam, be equipped with annular seal groove 7 on the sealing ring skeleton, seal groove department installs sealing ring 11.
Optimally, the SNS framework body, the reinforcing plate and the epoxy foaming glue injection cavity are integrally formed in an injection molding mode. Simple structure, preparation simple to operate, and overall structure is than stronger.
Further, integrated into one piece has sealing ring skeleton buckle 6 on the sealing ring skeleton, makes things convenient for the sealing ring skeleton to insert in the automobile body stand and through sealing ring skeleton buckle chucking, and simple to operate is swift and firm reliable.
According to the vehicle body framework with the sealed SNS composite structure, the vehicle body metal plate 3 is covered on the periphery of the vehicle body framework, the vehicle body metal plate is provided with the glue holes 2 corresponding to the injection molding ports of the epoxy foaming glue injection cavities, the epoxy foaming glue is injected into the epoxy foaming glue injection cavities in advance, after the vehicle body metal plate is covered on the periphery of the vehicle body framework, the epoxy foaming glue is foamed in the vehicle body coating and baking process, the cavity 9 formed by the enclosing of the plurality of criss-cross reinforcing plates is filled, and the SNS framework body and the vehicle body metal plate are firmly bonded together.
Because a plurality of criss-cross reinforcing plates and epoxy foam rubber injection cavities are integrally formed in the SNS framework body, the framework body is simple in structure, convenient and quick to manufacture, low in cost and light in weight. And epoxy foaming glue is at the automobile body application toasts the in-process, and epoxy foaming glue is heated the foaming, fills the cavity that encloses a plurality of vertically and horizontally staggered's reinforcing plate to can be in the same place with the firm bonding of SNS skeleton body and automobile body panel beating, very big increase the intensity of automobile body skeleton, improved the shock resistance intensity and the durability of automobile body.
And because the sealing ring framework is arranged, the structure is simple, the connection and the fixation of the vehicle body framework and the vehicle body upright column are convenient, and meanwhile, the good sealing performance of the vehicle body can be realized.
In conclusion, the vehicle body framework with the sealing type SNS composite structure, which is protected by the invention, has the advantages of simple structure and convenience in manufacturing and installation, and can improve the strength of the vehicle body against external impact and reduce the weight of the vehicle body.
Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
