The cycle frame of carbon fiber composite material

(1) technical field

The utility model relates to a kind of cycle frame of carbon fiber composite material, especially refer to that a kind of pipe fitting of forming vehicle frame is indivedual moulding, the end that combines is with box to pin or overlapping mode gluing combination, and gummed place appearance is again through mending the yarn processed, to finish whole vehicle frame, belong to the cycle frame device.

(2) background technology

The cycle frame of known carbon fiber composite material, when making moulding, it is one-body molded all will to form each pipe fitting integral body of vehicle frame with mould, and vehicle frame is one-body molded to have following disappearance existence on making:

1, one pair of mould of a kind of vehicle frame of moulding, a certain pipe shape one of forming vehicle frame changes, and whole pair of mould just can not use, and causes the moulding replaceability low.

2, whole vehicle frame is one-body molded, and not only the mould volume is big, and shaping speed is also slow.The vehicle frame volume is big, is easy to generate distortion during moulding, causes the high disappearance of fraction defective.

(3) novel content

Main purpose of the present utility model is to provide a kind of bicycle frame pipe of different shaping can be shared, saves die cost, moulding replaceability height, and the single manufacturing of pipe fitting has moulding simplification, lightweight, carbon fiber composite material cycle frame that product quality is high.

The cycle frame of a kind of carbon fiber composite material of the utility model, it is characterized in that: the pipe fitting of forming vehicle frame is indivedual moulding, hold with box to pin or overlapping mode gluing combination in combining afterwards, gummed place appearance is twined carbon cloth work benefit yarn processed again, forms complete vehicle frame.

It is as follows to repeat the technical solution of the utility model more in detail:

The cycle frame of a kind of carbon fiber composite material of the utility model mainly comprises: a standpipe; Pipe on one, an end is connected with the standpipe upper end; One back breeches pipe, the upper end is connected with the standpipe upper end, and the lower end is the prong shape, embeds for trailing wheel; Manage down for one, the upper end is curved shape and is connected with the last pipe other end, and tiltedly stretch to the back lower place lower end; The First Five-Year Plan siphunculus, front end is connected a pipe lower end down with head, and the upper end is connected with the standpipe lower end, and the rear end rear lower fork tube that extended back is connected a back hook between rear lower fork tube end and Seat stay pipe lower end; It is characterized in that: each pipe fitting joins after the end gluing to peg graft or overlapping mode engages again, and makes to mend the yarn processed in the joint appearance with carbon cloth again behind the joint.

Wherein, last pipe is connected the standpipe upper end with the Seat stay pipe binding end system is the nock shape, and mat nock and standpipe pipe outer wall overlap.

Wherein, two pipe fittings that the system of pegging graft is connected, a pipe fitting binding end tool one female joint wherein, another pipe fitting binding end tool one male joint, the mat box to pin plugs two pipe fittings.

Wherein, one section poor face of tool between pipe fitting body outer wall under the male joint, one section difference of tool between female joint and affiliated pipe fitting outer wall, make plug locate outer wall winding carbon cloth after, just section difference face is filled and led up.

The cycle frame of a kind of carbon fiber composite material of the utility model, each pipe fitting of its composition is that indivedual moulding are assembled again, so that has following advantage and effect on making and using:

1, volume is little during each formation of tubes, and moulding is simple, the tool lightweight.

2, the vehicle frame of different shaping, pipe fitting can be shared, saves die cost, and, moulding replaceability height, vehicle frame can change multiple moulding.

3, single pipe fitting volume is little, qualification rate height during manufacturing, and shorten overhours, improved production efficiency greatly.

(5) specific embodiment

See also Fig. 1～shown in Figure 7, the cycle frame of a kind of carbon fiber composite material of the utility model is made up of following pipe fitting:

One standpipe 10, the top is in order to connect seat cushion, the bottom has a female joint 11, contract in female joint 11 outer walls and standpipe 10 body outer walls between have one section and differ from 12.

Manage on one 20, one binding ends have a nock 21 in order to standpipe 10 upper end outer walls overlap joint, another binding end tool one female joint 22, contract in female joint 22 outer walls and last pipe 20 body tube outer walls between have one section and differ from 23.

One Seat stay pipe 30, the position is the fork-shaped setting at the rear of standpipe 10, and prong provides trailing wheel to embed.The binding end that connects standpipe 10 upper end outer walls is a nock 31, but mat nock 31 and standpipe 10 outer walls overlap joint.

Manage 40 down for one, the upper end is curved shape, and the end has a male joint 41 pegs graft with the female joint 22 of last pipe 20, and male joint 41 and head are managed between 40 body outer walls down has one section poor face 42; Extend to the back lower place lower end, and the end has a female joint 43, contracts in female joint 43 outer walls and head down has one section between pipe 40 body outer walls and differs from 44.

First Five-Year Plan siphunculus 50, female joint 11 ends that connect standpipe 10 bottoms have a male joint 51, and the two is pegged graft mutually with box to

51,11, has one section poor face 52 between male joint 51 and five-way pipe 50 outer walls.Meet the female joint 43 of managing 40 lower ends under head and have a male joint 53, have one section poor face 54 between male joint 53 and five-way pipe 50 body outer walls, mat male joint 53 and head are managed 40 female joint 43 grafting down.Meet upper branch pipe 30 lower ends backward and be extended with the rear lower fork tube 55 of one, 55 of Seat stay pipe 30 and rear lower fork tubes are connected with a back hook 60.

After the indivedual moulding of each carbon fibre reinforced pipe spare, after cutting the fraising trimming, submit again to the gummed platform.With the nock gluing respectively of the pipe fitting box to pin that plugs and overlap joint, and then peg graft mutually or overlap joint (as Fig. 6, shown in Figure 7) in addition.On the segmentum laterale difference face that plugs the place, do to twine the benefit yarn processed of carbon cloth 70, the seam of box to pin joint is covered and section difference face is mended flat, trim and strengthen the stress (as Fig. 1～shown in Figure 5) of joint with the pipe fitting outer wall.Last pipe 20 and Seat stay pipe 30 and standpipe 10 lap-joints behind the gluing overlap joint, are also twined carbon cloth 70 again in lap position and are made to mend the yarn processed, the appearance of lap-joint are made the stress of coating decoration and reinforcement lap-joint.After each pipe fitting is connected with group, promptly finish a complete cycle frame.
