In other words, when a small amount of adhesive passes through the edge bead 404 from the inside of the bonding region 403 to the outside due to poor manufacturing precision, the adhesive-blocking ring 407 can perform a second layer of physical blocking to the adhesive, preventing the adhesive from leaking to the outside of the adhesive-blocking ring 407.

The glue retaining ring 407 has an expanded state such that the outer diameter of the glue retaining ring 407 is larger than the outer diameter of the edge bead 404, thereby sealing the end of the glue joint area 403, preventing the leakage of the glue, and also controlling the amount of glue injected.

When keeping off gluey ring 407 and receive high temperature toast, keep off gluey ring 407 and be heated and take place the inflation, make the volume grow to make and keep off gluey ring 407 and the laminating of the sleeve inner wall that corresponds better, keep off gluey ring 407 cooperation edge and keep off the tip that muscle 404 closed the regional 403 that splices, provide the enclosure space for the injection of adhesive. By utilizing the self-expansion performance of the glue blocking ring 407, the glue blocking ring only needs to be cut into simple sheets and attached to two sides of the gluing area 403, and after expansion, the glue blocking ring can be automatically filled according to the size of a gap between the fiber reinforced composite material reinforcing beam 400 and the inner wall of the corresponding sleeve, so that the design difficulty and the processing cost are greatly reduced.

Optionally, the rubber retaining ring 407 is a rubber-foaming agent mixed material rubber retaining ring, a rubber material rubber retaining ring, or a plastic material rubber retaining ring.

The glue blocking ring 407 is fixedly adhered to the fiber reinforced composite material reinforcing beam 400.

The expansion ratio of the material of each glue blocking ring 407 is 2-10 times. For example, the expansion ratio of each stopper ring 407 is 5 times or 8 times. The expansion ratio of the glue retaining ring 407 can be selected according to the size of the filling space.

The width of each glue blocking ring 407 is 5mm-15mm, and the thickness is 0.5mm-5 mm. For example, each glue retaining ring 407 has a width of 10mm and a thickness of 3 mm. The glue blocking ring 407 may be directly attached to the outer surface of the fiber reinforced composite reinforcement beam 400 after being cut according to the design size.

In addition, when the bonding area 403 is filled with the adhesive, the thickness of the adhesive layer is equal to that of the boss 405, that is, the boss 405 also has the function of controlling the thickness of the adhesive layer. The function of the boss 405, i.e., the function of the gap control structure, is not described herein in detail.

Optionally, the boss 405 is a circular boss, and the axis of the circular boss is perpendicular to the outer surface of the fixed section 402 that is in contact with the circular boss.

The glue blocking ring 407 has excellent gap size adaptability, gaps of different sizes, caused by design and caused by component tolerance can be automatically filled through expansion, the problem that the gluing area 403 is not tightly sealed is solved by arranging the glue blocking ring 407 outside the gluing area 403, and the gluing area 403 is completely sealed.

Optionally, the fiber reinforced composite reinforcement beam 400 is a carbon fiber composite reinforcement beam, the carbon fiber composite reinforcement beam is a lightweight material with excellent performance, and the fiber reinforced composite reinforcement beam 400 is made of the carbon fiber composite material, so that the weight of the fiber reinforced composite reinforcement beam 400 can be reduced while the strength is ensured, and the lightweight design of a vehicle is facilitated.

A fiber reinforced composite reinforcement beam 400 according to an embodiment of the present invention is described in detail below with reference to fig. 1 to 16.

Referring to fig. 1, 3-4, a fiber reinforced composite reinforcement beam 400 includes: the reinforcing beam comprises a reinforcing beam body 401 and fixing sections 402 arranged at two ends of the reinforcing beam body 401, wherein the fixing sections 402 are used for connecting pieces in the side wall cavity 1003. As shown in fig. 1, the fixing section 402 at the front end of the fiber reinforced composite material reinforcing beam 400 is adapted to be connected with the a-pillar connector 100, and the fixing section 402 at the rear end of the fiber reinforced composite material reinforcing beam 400 is adapted to be connected with the C-pillar reinforcing plate 300, so that the installation of the fiber reinforced composite material reinforcing beam 400 in the side wall cavity 1003 can be realized.

The fixed section 402 is suitable for being fixed with the side wall of the side wall cavity 1003, and the fiber reinforced composite material reinforcing beam 400 has a shape following structure matched with the side wall cavity 1003. In other words, the fiber reinforced composite material reinforcing beam 400 is of a variable axis structure, that is, the axis of the fiber reinforced composite material reinforcing beam 400 is a curve, so that the fiber reinforced composite material reinforcing beam 400 meets the curvature change of the side wall cavity 1003 in the front and rear direction of the vehicle, and the shape of the fiber reinforced composite material reinforcing beam 400 changes along with the profile of the side wall inner plate 1001, thereby ensuring that the fiber reinforced composite material reinforcing beam 400 is better installed in the side wall cavity 1003.

In addition, the length of the fiber reinforced composite material reinforcing beam 400 can be designed according to the size of the vehicle body, and the requirement that the A column to the C column penetrate through the side wall cavity 1003 at the upper part of the side wall is met.

According to the utility model discloses fibre reinforced composite stiffening beam 400 through set up fibre reinforced composite stiffening beam 400 in the side wall die cavity 1003 of vehicle side wall, can increase the intensity of vehicle side wall to promote the crashworthiness of vehicle. Compared with a common metal tubular beam, the fiber reinforced composite material reinforcing beam 400 is low in density and light in weight, the weight of the vehicle body cannot be increased remarkably, and light-weight design of the vehicle is facilitated.

The cross-sectional area of the fiber reinforced composite reinforcement beam 400 is constant or gradually increases in the vehicle front-to-rear direction. Since the fiber reinforced composite reinforcement beam 400 is fabricated by a 3D weaving process, in some alternative embodiments, the cross-sectional area of the fiber reinforced composite reinforcement beam 400 may be designed to be constant, thereby simplifying the processing process of the fiber reinforced composite reinforcement beam 400.

Referring to fig. 9, 12 and 15, the cross section of the fiber reinforced composite reinforcement beam 400 is a closed section having a substantially quadrangular or circular shape. From the mechanical point of view, by constructing the cross section of the fiber reinforced composite reinforcement beam 400 as a closed section, the rigidity of the fiber reinforced composite reinforcement beam 400 can be effectively improved compared to an open section.

The cross section of the fiber reinforced composite material reinforcing beam 400 is special-shaped, the cross section shape and the size are variable, and the variation of the perimeter of the cross section of the fiber reinforced composite material reinforcing beam 400 is not more than 30%, so that the fiber reinforced composite material reinforcing beam 400 can be better matched with the side wall cavity 1003.
