Abstract
The utility model relates to a bicycle frame pipe structure of carbon fiber composite, which is characterized in that each trisection position of the inner wall of the bicycle frame pipe is respectively provided with a rib, the three ribs are cross connected with each other in the axial center. With the radial connection of the three ribs and the trisection position of the inner wall of the bicycle frame pipe, the utility model has the efficiency of supporting strength of structure of the bicycle frame pipe wall, thereby strength of structure of the whole bicycle frame pipe can be upgraded, at the same time, the lateral rigidity and longitudinal shock resistance of the bicycle frame pipe can be upgraded.
Description
(1) technical field:
The utility model provides a kind of cycle frame tubular construction of carbon fiber composite material, refers to the cycle frame tubular construction of the carbon fiber composite material of a kind of lateral rigidity that can promote the vehicle frame pipe simultaneously and vertical impact resistance especially, belongs to bicycle assembly parts.
(2) background technology:
The bicycle frame tube that carbon fiber composite material is made has the light weight effect, can alleviate the weight of whole bogie frame greatly, so that is extensive use of by industry in recent years.But in order to promote the structural strength of carbon fiber composite material cycle frame, the dealer is arranged before the moulding of vehicle frame pipe, in the vehicle frame pipe, preset pipe (as the Taiwan utility model patent, the patent No. is M303166, hereinafter to be referred as known case) in two semicircles.Pipes were arranged side by side to face end phase closing mode directly in known case two was semicircle, make the vehicle frame pipe moulding of carbon fiber composite material after, inside has in two pipe fits with the vehicle frame inside pipe wall, and two semicircle in pipes face the rib that the end nature forms the tool strengthening action directly.Known case is for promoting the structural strength of carbon fiber composite material vehicle frame pipe, in vehicle frame, preset the way of pipe in two semicircles, though the structural strength to the vehicle frame pipe is helpful, the builder there is the extra heavy disappearance of weight that consumes worker, cost height and make carbon fiber composite material vehicle frame pipe.And the setting of rib no matter be to adopt horizontal type ornaments or vertically setting, all only can promote the rigidity of vehicle frame pipe single direction, can't take into account lateral rigidity or vertical impact resistance of vehicle frame pipe.Consequently, known case still has disappearance to exist on structural strength.
(3) utility model content:
The cycle frame tubular construction of a kind of carbon fiber composite material of the utility model its objective is: the cycle frame tubular construction that the carbon fiber composite material of a kind of lateral rigidity that can promote the vehicle frame pipe simultaneously and vertical impact resistance is provided.
The cycle frame tubular construction of a kind of carbon fiber composite material of the utility model: the inside pipe wall trisection place of vehicle frame pipe has a rib respectively, three ribs join in vehicle frame pipe tubular axis heart place, this three rib of mat is radial to be connected with the third-class office of vehicle frame inside pipe wall, effect with support frame tube wall structural strength, to promote the structural strength of whole vehicle frame pipe, the lateral rigidity of vehicle frame pipe and vertical impact resistance are promoted simultaneously.
Wherein, a rib can be done vertically to setting.
Wherein, when the vehicle frame pipe is last pipe, the rib of this vertical direction can be up.
Wherein, pipe under the vehicle frame pipe is, the rib of this vertical direction can be down.
Wherein, back breeches pipe under the vehicle frame pipe is, the rib of this vertical direction can be down.
Advantage of the present utility model and effect are: promoted lateral rigidity and vertical impact resistance of bicycle frame tube, strengthened the structural strength of vehicle frame pipe.
(4) description of drawings:
Figure 1 shows that the lateral plan of the utility model first embodiment.
Figure 2 shows that 2-2 cutaway view among Fig. 1.
Figure 3 shows that 3-3 cutaway view among Fig. 1.
Figure 4 shows that 4-4 cutaway view among Fig. 1.
Figure 5 shows that the cutaway view of the utility model second embodiment.
Number in the figure is as follows:
12 pipes of 11 times pipes of pipe on 10
Back breeches pipe on 13 standpipes, the 14 five-way pipes 15
16 times back breeches pipe 17 colludes pawl A rib
(5) specific embodiment:
The cycle frame tubular construction of a kind of carbon fiber composite material of the utility model sees also Fig. 1～shown in Figure 4, and the vehicle frame pipe of cycle frame comprises manages 10 on one; Manage 11 once; One connects the head pipe 12 of upper and lower pipe 10,11; One top connects the seat cushion vertical tube and sidewall and last pipe 10 other end bonded assembly standpipes 13; First Five-Year Plan siphunculus 14, the top connects standpipe 13 bottoms, and front end connects the other end of pipe 11 down; Back breeches pipe 15 on one, and the top is connected with standpipe 13 top sidewalls; Once back breeches pipe 16, and front end is connected with five-way pipe 14 ends; Reach one and collude pawl 17, be used for connecting the rear end of back breeches pipe 15, following back breeches pipe 16.
See also Fig. 2～shown in Figure 4, in the vehicle frame pipe (as above manage 10, manage down 11 and back breeches pipe 16 etc. down) the third-class office of inside pipe wall (120 degree of promptly being separated by) have a rib A respectively to the handing-over of tubular axis heart place (rib A can with vehicle frame pipe with body formed), the setting of three radial rib A of mat has the effect that supports whole prop stand pipe, promotes vehicle frame tubular construction intensity.Wherein, the direction that is provided with of a rib A is to do the vertical direction setting, and especially, when the vehicle frame pipe was last pipe 10, vertical rib A can be provided with up, (as shown in Figure 2); When the vehicle frame pipe is following pipe 11 and (as shown in Figure 3, Figure 4) during back breeches pipe 16 down, vertical rib A can be provided with down, to promote vertical impact resistance of vehicle frame pipe.Because the vehicle frame inside pipe wall also has two rib A respectively to the oblique support frame tube wall in both sides outside vertical ribs A, consequently, two oblique rib A have the effect that promotes vehicle frame pipe lateral rigidity.
Secondly, see also shown in Figure 5ly, no matter whether the vehicle frame pipe is pipe or non-pipe, all can have a rib A respectively, and three rib A are also in the handing-over of vehicle frame pipe tubular axis heart place, to promote the structural strength of vehicle frame pipe at vehicle frame pipe inside pipe wall trisection place.
By above-mentioned explanation as can be known, the utility model respectively is provided with a rib A in the third-class office of vehicle frame pipe inside pipe wall, and three rib A join in vehicle frame pipe tubular axis heart place, can promote the structural strength of whole prop stand pipe, and the vertical impact resistance, the lateral rigidity that promote the vehicle frame pipe, this structure has practicality and progressive more than known case.
