The specific embodiment
Below in conjunction with accompanying drawing the structural principle and the principle of work of the utility model are done concrete description:
The front elevation of Fig. 1 the utility model first preferred embodiment;
The partial perspective view of Fig. 2 the utility model first preferred embodiment;
The cutaway view of Fig. 3 a, first preferred embodiment of Fig. 3 b the utility model;
The scheme drawing of Fig. 4 the utility model second preferred embodiment; And
Fig. 5 is the scheme drawing of the utility model the 3rd preferred embodiment.
See also Fig. 1 to Fig. 3 a, Fig. 3 b, the Strengthening bicycle frame 10 of the bicycle of the utility model first preferred embodiment is made and include pipeline section 12, a lower tube section 13 and six ribs 14～19 on the pipe 11, by fiber reinforced material.This Strengthening bicycle frame 10 is made by fibre reinforced resin in the present embodiment, and this fiber is a carbon fiber, also can adopt boron fiber, fibrous glass or Ke Weila (Kevlar) fiber during actual the manufacturing, and this resin can be thermosetting resin or thermoplastic base resin.
Should go up pipeline section 12 is to be extended back integratedly by these pipe 11 tops.
This lower tube section 13 is to be extended back integratedly and be positioned at pipeline section 12 belows on this by these pipe 11 bottoms; This pipe 11, the inside of pipeline section 12 and this lower tube section 13 is connected and forms car head 20 jointly this on; This car first 20 has one by this pipe 11, the common inside face 201 that forms of inside face of pipeline section 12 and this lower tube section 13 this on, and a room 202 that is defined by this inside face 201.
This six rib 14～19 respectively has a coupling end and a free end away from this coupling end.Is the example explanation in this with a rib 17 wherein, and this rib 17 has a coupling end 171 and is connected with the inside face 201 of this car first 20, and a free end 172 away from this coupling end 171 is arranged in the room 202 of this car head 20.In the present embodiment, a rib 14 is positioned at the front side of this pipe 11 and roughly along the extending axially of this pipe 11, and is noted that the front side here is that to drive direction with bicycle be that the place ahead defines, the direction definition in the back literary composition also with; Other has two ribs 15,16 to lay respectively at the left and right side of this pipe 11 and extending axially along this pipe 11 roughly; And this rib 17 is the right sides that extended to this lower tube section 13 by the left side of pipeline section on this 12 via this pipe 11; There is a rib 18 to extend to the left side of this lower tube section 13 via this pipe 11 by the right side of pipeline section on this 12 again; And there is a rib 19 to extend to the upside of this lower tube section 13 by the downside of pipeline section on this 12.The section shape of present embodiment center rib 14～19 is rectangular, and height is little than width, and the section shape of rib can change, and all can like square, semicircle, half elliptic, triangle or trapezoidal.
This six rib 14～19 can increase the structural strength of this Strengthening bicycle frame 10 significantly, and the structural strength of this Strengthening bicycle frame 10 cars first 20 (i.e. this head pipe 11, on this pipeline section 12 and this lower tube section 13) particularly but only increases the weight of car head 20 a little.
