Abstract
The invention relates to a longitudinally-folding bicycle frame, which comprises a clamping slot, an elastic rubber block, a folding rotating shaft, a folding rear bicycle frame, a five-way joint, a bicycle-frame upper pipe and a head pipe, wherein the clamping slot is connected with the elastic rubber block; the folding rear bicycle frame is connected with the folding rotating shaft; the elastic rubber block is fixedly arranged on the folding rear bicycle frame; the bicycle-frame upper pipe is connected with the five-way joint, and the bicycle-frame upper pipe is connected with the head pipe. According to a folding bicycle-frame structure provided by the invention, the folding of a traditional folding box is not needed, so that the weight of the folding box is omitted, and a whole bicycle can he lightened by more than 400g; furthermore, because the folding mode is a longitudinal shaft-surrounding mode, the longitudinally-folding bicycle frame is folded in place by one step, so that the longitudinally-folding bicycle frame is quite convenient; moreover, compared with an ordinary folding bicycle frame, the weight of the folding bicycle frame provided by the invention is markedly lightened, so that the folding bicycle frame is more convenient to use and carry and is suitable for the use of ordinary consumers.
Description
Technical field
The present invention relates to the body frame structure for automotive of folding bicycle, more specifically, relate to a kind of longitudinal-folding bicycle frame.
Background technology
The maximum advantage of folding bicycle is to fold, and is convenient for carrying.But the important parameter that folding bicycle is convenient for carrying is weight.Lightweight folding bicycle is more subject to the welcome of customer.At present, wheel 14 cun, footpath or 16 cun of complete vehicle weights the lightest at 6.5-7.5 kilogram, due to the restriction of structure, do not exist at present lower than the folding car load of 6.5 kilograms.But, when a folded bicycle is when lower than less than 6.5 kilograms or 5 kilograms, carry the feeling relaxed that ability is real.
But the key addressed this problem is vehicle frame and the accessory of folding bicycle.At present, vehicle frame and the accessory of folding bicycle adopt aluminum alloy mostly, material can not there is larger breakthrough, because uniquely can substitution of Al alloy be magnesium alloy and titanium alloy, but this bi-material, in actual production, due to high costs or material, to be used in technology on folded bicycle immature, do not used in enormous quantities by actual production always.Like this, if make the folding complete vehicle weight of 14 cun or 16 cun break through the current limitation of more than 6.5 kilograms, only has a kind of possibility, change the structure of existing car load vehicle frame and accessory exactly, and, this change must be break through original know-why, and the structural development in original know-why can not fundamentally address this problem.
Summary of the invention
For above-mentioned problems of the prior art, the object of this invention is to provide one and complete vehicle weight can be made ultralight, portable, can the folding frame for bicycle of fundamentally technical solution problem.
In order to realize the object of foregoing invention, the present invention adopts following technical scheme:
A kind of longitudinal-folding bicycle frame, comprise draw-in groove, elasticity blob of viscose, folding rotary shaft, folding rear carriage, five-way, top tube and head tube, wherein said draw-in groove is connected with described elasticity blob of viscose; Described folding rear carriage is connected with described folding rotary shaft; Described elasticity blob of viscose is fixed on described folding rear carriage; Described top tube is connected with described five-way, and described top tube is connected with described head tube.
Further, the lower end hollow out of described top tube, described five-way embeds wherein.
Further, the non-end hollow out of weighing of described head tube.
Further, described folding rotary shaft is the rotating shaft of excellent power glue.
Further, described folding rear carriage is when car load using state, and described elasticity blob of viscose snaps in draw-in groove.
Owing to adopting above technical scheme, beneficial effect of the present invention is:
Folding stand structure provided by the invention, does not need the folding of traditional folded box, eliminates the weight of folded box, car load can be made light more than 400 grams.More because folding mode is longitudinally around axle mode, a step is folding to put in place, very convenient.And the common folding stand of folding stand weight ratio provided by the invention obviously alleviates, and is more conducive to use and carry, be applicable to the use of ordinary consumer.

2 longitudinal-folding bicycle frame structures, 21 folding rotary shafts, 22 folding rear carriages, 23 elasticity blob of viscoses, 24 draw-in grooves, 25 five-ways, 26 top tubes, 27 head tubes.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Be illustrated in figure 1 whole the bicycle structure schematic diagram being provided with folding stand structure 2 provided by the invention.
As shown in Fig. 2,3,4,5, a kind of longitudinal-folding bicycle frame provided by the invention, comprise draw-in groove 24, elasticity blob of viscose 23, folding rotary shaft 21, folding rear carriage 22, five-way 25, top tube 26 and head tube 27, wherein draw-in groove 24 is connected with elasticity blob of viscose 23; Folding rear carriage 22 is connected with folding rotary shaft 21; Elasticity blob of viscose 23 is fixed on folding rear carriage 22; Top tube 26 is connected with five-way 25, and top tube 26 is connected with head tube 27.
In above-mentioned optimal technical scheme, the lower end hollow out of top tube 26, five-way 25 embeds wherein; The non-end hollow out of weighing of head tube 27; Folding rotary shaft 21 is the rotating shaft of excellent power glue; Folding rear carriage is when car load using state, and elasticity blob of viscose 23 snaps in draw-in groove 24.
This folding stand structure of the present invention, its folding rear carriage 22 realizes the longitudinal folding of folding bicycle by folding rotary shaft 21, and elasticity blob of viscose 23 has damping effect, is fixed on folding rear carriage 22, when Rear frame 22 is in car load using state, elasticity blob of viscose 23 snaps in draw-in groove 24.
Folding stand structure of the present invention is in the lower end hollow out of top tube 26, and five-way 25 embeds wherein, reduces over many traditional welding beads and piles up the weight increase and outward appearance problem of rough that bring.
Folding stand structure of the present invention removes material, hollow out loss of weight at the non-bearing end of head tube 27.Therefore, adopt the folding stand structure of technique scheme, do not need the folding of traditional folded box, eliminate the weight of folded box, car load can be made light more than 400 grams.More because folding mode is longitudinally around axle mode, a step is folding to put in place, very convenient.And the common folding stand of this folding stand weight ratio obviously alleviates, and is more conducive to use and carry, be applicable to the use of ordinary consumer.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in the claims in the present invention.
