Abstract
The utility model discloses a bicycle beam reinforcing structure, which comprises a bicycle beam, a head tube, a seat tube and a reinforcing rod. The front of the bicycle beam is welded with the head tube. The reinforcing rod is divided into two butted parts, which are a front part and a rear part. The front portion of the reinforcing rod is welded with the front part of the bicycle beam and the rear portion thereof is welded with the seat tube. The bending resistance section coefficient at the abutting face of the reinforcing rod is less than that at the front part or the rear part of the reinforcing rod. By adopting the above structure, the bearing effect of the reinforcing rod is greatly improved.
Description
Technical field
The utility model relates to reinforced structure, particularly a kind of bicycle car beam reinforced structure.
Background technology
Folding bicycle is very popular, and the folding bicycle of numerous species has been arranged on the market, the vehicle body front and back ends can be folded, and perhaps handlebar vertical tube, seat pipe etc. is carried out telescopic folding.In the file of Chinese patent application CN 00260163.X, the applicant has described a kind of " reinforcing mechanisms of single-beam folding bicycle folding joint ", shown in Figure 1 as this patent, this bicycle is equipped with a stirrup that can participate in folding between car beam and standpipe, when bicycle is in deployed condition, standpipe, car beam and stirrup constitute triangle jointly, and folding joint is positioned on the leg-of-mutton car beam; But its car beam is when folded state, as its Fig. 2, stirrup protrudes in the outside, when stressed, rock easily, seem unstable, even under the riding condition of two stirrups butt joint, stirrup still shows thinly, yielding under external impacts, this is all because cantilever is long and stirrup itself carefully causes.
The utility model content
The utility model aims to provide a kind of stirrup and participates in the car beam when folding, the constructional device of load better effects if, and this reinforced structure is easy to processing, the manufacturing of manufacturing line simultaneously, and applicability is strong, and cost is low, is convenient to promote.
The utility model is achieved in that bicycle car beam reinforced structure, comprise Che Liang, head pipe, seat pipe and stirrup, described car beam front end is welded in the head pipe, described stirrup is divided into forward and backward two sections of butt joint, described stirrup front end is welded in car beam leading portion, described stirrup rear end is welded in the seat pipe, and it is characterized in that: in vertical direction, the bending resistant section coefficient at described stirrup interface place is less than the bending resistant section coefficient of stirrup leading portion or back segment.
In the zone that described car beam, stirrup and seat pipe are surrounded, reinforced rib is set.
Described reinforced rib is arranged between stirrup back segment and the seat pipe.Between stirrup leading portion and car beam leading portion, reinforced rib is set.
Described stirrup interface place diameter is little, and the diameter of stirrup front end and stirrup rear end is big.
The utility model bicycle car beam reinforced structure perhaps is provided with reinforced rib between seat pipe and the stirrup between car beam and stirrup, greatly improved the load effect of stirrup.This improvement shows under folded state and the riding condition, and when at folded state, stirrup obviously protrudes in a side, is being subjected under the accidental action power yieldingly, and built on the sand, the setting of reinforced rib has solved this problem well; When under riding condition, this reinforced rib has then increased the vehicle frame whole rigidity, and is more firm under the impulsive force of riding.In addition, the structure of the concavo-convex butt joint of stirrup interface also makes stirrup itself be difficult for disconnecting and the front and back combination is stablized.

The specific embodiment
Below in conjunction with accompanying drawing the utility model bicycle car beam reinforced structure is described in further details.
As Fig. 1, the utility model bicycle car beam reinforced structure comprises car beam, seat pipe, head pipe, stirrup, this car beam comprises car beam leading portion 11, car beam back segment 12, folding joint 5 is installed on the involutory surface of the two, this joint 5 is hinged in car beam one side, opposite side is provided with lock handle, and this car beam leading portion 11 is welded in head pipe 4, and car beam back segment 12 is welded in seat pipe 3.Be provided with stirrup between this car beam leading portion 11 and the seat pipe 3, this stirrup comprises stirrup leading portion 21, stirrup back segment 22, the two butt joint.Stirrup leading portion 21 is welded in car beam leading portion 11, and stirrup back segment 22 is welded in seat pipe 3, is provided with reinforced rib 6 between this back segment 22 and the seat pipe 3, and this reinforced rib 6 is the reinforcement metal sheet or the metal tube of welding.In addition, can also between car beam leading portion 11 and stirrup leading portion 21, reinforced rib 7 be set.Can obviously improve the load effect of stirrup 21,22 like this in diagram F vertical direction, stable, shock-resistant more.
As Fig. 2, second embodiment for the utility model bicycle car beam reinforced structure, the basic structure of its car beam, stirrup is identical with first embodiment, difference is, reinforced rib 8 is set directly between stirrup back segment 22 and the car beam back segment 12, and this reinforced rib 8 is sheetmetal, metal tube or Metallic rod.
Another embodiment takes all factors into consideration and goes up dual mode,, between stirrup back segment 22 and car beam back segment 12 reinforced rib 8 is set that is, is provided with reinforced rib 6 simultaneously between back segment 22 and seat pipe 3, between car beam leading portion 11 and stirrup leading portion 21 reinforced rib 7 is set.
As Fig. 3, the 3rd embodiment, stirrup leading portion 21 is welded in head pipe 4 respectively with car beam leading portion 11, promptly head pipe, car beam, stirrup and seat pipe constitute a quadrangle, can between stirrup back segment 22 and car beam back segment 12, reinforced rib 8 be set, also can between stirrup leading portion 21 and car beam leading portion 11, reinforced rib 9 be set simultaneously.
Another embodiment, described stirrup interface 23,24 place's diameters are little, and the diameter of stirrup front end and stirrup rear end is big.
Another embodiment, described stirrup are hollow tubular, and described stirrup interface 23,24 place's thickness of pipe are little, and stirrup front end and rear end pipe wall thickness are big.
As Fig. 4, the 4th embodiment, dull and stereotyped reinforcing chip 10 are arranged between stirrup back segment and car beam back segment, and this flat board reinforcing chip 10 is a sheetmetal, and this reinforcing chip upper end is wide and the lower end is narrow, are similar to del.
As Fig. 5, formerly in the technology, the interface 23,24 of stirrup is the plane butt joint, Yi Bian perhaps be the arc plush copper, another side is an arc groove, but this butt joint still seems stable inadequately.In the utility model, as Fig. 4, the interface 23 of stirrup leading portion 21 is the protruding end, and the middle part of this interface 23 is provided with the cylindrical structure 231 of protrusion, correspondingly, the middle part of interface 24 is provided with cylinder shape groove 241, and the external diameter of this protruding end 231 is slightly less than the internal diameter of groove 241, like this, under the cycling state, protruding end 231 is docked at groove 241 inside fully, has limited the alternate displacement of stirrup under impulsive force well, thereby has guaranteed safety.Protruding end 231 and the groove 241 forward and backward position on stirrup can be exchanged, to not influence of the technical program.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
