The invention provides a B-pillar structural reinforcement, which relates to the field of automotive reinforcements, and includes a fixed frame, an expanded adhesive adhered to the surface of the fixed frame, and a fixed buckle. The overall top-view projection of the fixed frame is trapezoidal, and the fixed frame The middle part is provided with a raised adhesion part, the side is provided with a connection port integrally formed with the fixed frame, the two sides of the adhesion part are provided with reinforcing ribs, and the expanded adhesive is adhered to the surface of the adhesion part. The fixing buckle is connected with the connection port. The fixed frame of the present application improves the side impact and top pressure performance of the vehicle body through the combined action of the reinforcing rib plate and the expanded adhesive, reduces the weight of the vehicle body, thereby simplifies the partial sheet metal structure of the vehicle body, and has the characteristics of easy manufacture and convenient installation.
Description
Technical Field
The invention relates to an automobile reinforcing part, in particular to a B-pillar structural reinforcing part.
Background
Structural reinforcements are now widely used in the automotive industry, have the characteristics of light weight and high specific strength, have become another composite tool for body design engineers to provide structural support or reduce noise/vibration. For example, in vehicle body structures, reinforcements are used primarily in the beam, pillar, cross member, critical hinge points, door frames, etc. locations of the vehicle. Typically, the structural reinforcement is made up of three parts, a nylon fiberglass skeleton, an epoxy structural expansion adhesive, and a pre-installed snap or weld tab, the structural expansion adhesive material being typically in an unexpanded state when the reinforcement is made, but being activated, such as by heating, to cause expansion and thereby bond to the surface of the structural member. In the automotive field, heating is usually carried out during the processing in automotive paint shops.
In the existing automobile body design, the B column position is used for improving the side impact and top pressure performance, the number and thickness of metal plates can be continuously increased, and thus, great pressure is caused on the cost.
Therefore, it is an urgent technical problem to be solved by those skilled in the art to design a B-pillar structural reinforcement.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a B-pillar structural reinforcement.
The invention is realized by the following technical scheme: the utility model provides a B post structure reinforcement, its characterized in that, includes fixed skeleton, the adhesion is at the inflation viscose and the fixed buckle on fixed skeleton surface, the holistic overlook projection of fixed skeleton is trapezoidal, and the middle part of fixed skeleton is equipped with bellied adhesion portion, and the side is equipped with the connector with fixed skeleton integrated into one piece, the both sides of adhesion portion are equipped with the reinforcing floor, the inflation viscose glues at the surface of adhesion portion, fixed buckle links to each other with the connector.
According to the above technical scheme, preferably, the center of the adhering part is provided with a positioning hole.
According to the above technical solution, preferably, the reinforcing rib is disposed obliquely downward from the edge of the self-adhesive portion to the edge of the fixing frame.
The invention has the beneficial effects that: the fixed framework of the application improves the side impact performance and the top pressure performance of the automobile body through the combined action of the reinforcing rib plates and the expansion adhesive, and reduces the weight of the automobile body, thereby simplifying the local sheet metal structure of the automobile body, and having the characteristics of easy manufacture, convenient installation and the like.
Drawings
Fig. 1 shows a block diagram of an embodiment of the present invention.
Fig. 2 shows a side view of an embodiment of the invention.
In the figure: 1. fixing the framework; 2. expanding the viscose; 3. fixing the buckle; 4. an adhesive portion; 5. a connecting port; 6. a reinforcing rib plate; 7. and (7) positioning the holes.
Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figures, the invention provides a B-pillar structural reinforcement, which is characterized by comprising a fixed framework 1, an expansion adhesive 2 adhered to the surface of the fixed framework 1 and a fixed buckle 3, wherein the overall overlook projection of the fixed framework 1 is trapezoidal, a raised adhesion part 4 is arranged in the middle of the fixed framework 1, a connector 5 integrally formed with the fixed framework 1 is arranged on the side edge of the fixed framework 1, reinforcing rib plates 6 are arranged on two sides of the adhesion part 4, the expansion adhesive 2 is adhered to the surface of the adhesion part 4, and the fixed buckle 3 is connected with the connector 5.
According to the above embodiment, it is preferable that the adhesive part 4 is provided with the positioning hole 7 at the center.
According to the above embodiment, preferably, the reinforcing ribs 6 are provided obliquely downward from the edge of the self-bonding portion 4 to the edge of the fixing frame 1.
The working principle of the invention is as follows: glue 2 to the adhesion portion 4 of fixed skeleton 1 with the inflation viscose, fixed skeleton 1 is the fine manufacturing of nylon glass, the fine content of glass is at 35%, low density, it is light to have a structure, specific strength big characteristics, under the combined action with the reinforcing floor 6 that sets up on fixed skeleton 1, increase the resistance to deformation ability of the regional panel beating of B post, according to locating hole 7 and fixed buckle 3's combined action, make fixed skeleton 1 and automobile body panel beating be connected, like this when the inflation viscose is heated the inflation back, can be full of the B post cavity, play the support, fall the effect such as making an uproar.
The invention has the beneficial effects that: the fixed framework 1 improves the side impact performance and the top pressure performance of the automobile body through the combined action of the reinforcing rib plate 6 and the expansion adhesive, reduces the weight of the automobile body, simplifies the local sheet metal structure of the automobile body, and has the characteristics of easiness in manufacturing, convenience in mounting and the like.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
