Description

A kind of carbon fiber seat cushion that produces deformation

Technical field

The utility model relates to a kind of carbon fiber seat cushion.

Background technology

Zui Jia carbon fiber seat cushion now, announcing M241301 number " the seat cushion structure of bicycle use " as TaiWan, China provides, be below the carbon fiber seat cushion, one Extendible flake of springing up and down to be installed near the position of back edge, this Extendible flake is provided with two tailstocks, end winding with bracing frame, and the other end of bracing frame is fixed on the position of seat cushion below near front edge by the nose seat, when the rider is sitting in the highway section of passing through uneven on the seat cushion, seat cushion can swing up and down by Extendible flake, reaches the effect of shock-absorbing buffering.

Yet, when stating structure in the use, when rider's a pin is trampled downwards, can affect the thigh and the buttocks of a corresponding side, make this half part of seat cushion produce side direction drag on one side, meanwhile, rider's another pin is upwards carried, can not exert oneself, then this of seat cushion half part can not produce the drag on this limit of side direction, therefore when using bicycle to trample, part need be born asymmetric drag about seat cushion, the said structure this asymmetric drag of can not releiving, do not meet principle of human engineering fully, when the rider tramples for a long time, not only cause human discomfort, also have the defective of the effort of trampling.

In view of this, the inventor finishes this case, with the problem that exists in the thorough solution said structure finally through the test of many times design.

The utility model content

The purpose of this utility model is to provide a kind of carbon fiber seat cushion that produces deformation, and it has preferable toughness, meets principle of human engineering, and ride comfort is trampled laborsaving.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of carbon fiber seat cushion that produces deformation comprises seat portion and the backplate portion that can Gong take, in the middle of seat portion is positioned at, and the front edge of bottom surface is provided with the nose seat, rear end then neighbour is provided with tailstock, and group is established an elastic bow between nose seat and the tailstock, and seat portion is located on the bicycle saddle tube by the elastic bow group; Backplate portion is located at all sides of seat portion, and with seat portion corral, seat cushion is the form of surfacing, and the bottom surface of seat portion also is provided with a binding layer, but this binding layer is to insert and put a heat plastic one by the fiber material that soaked epoxy resin to be subjected to the mould heat pressure moulding.

But above-mentioned binding layer is to insert and put the heat plastic up and down by the fiber material that soaked epoxy resin, and is hot-forming by the mould one again, has the thermoplastic layer of thermoset layer, fibrage and clamping combination, wherein, thermoplastic layer all have thermoset layer and fibrage up and down.

Above-mentioned seat portion and backplate portion wall unevenness etc.

After adopting said structure, the utility model is subjected to the mould heat pressure moulding because the binding layer use of seat portion bottom surface is established a thermoplasticity material one by the fiber material folder that soaked epoxy resin, has elasticity preferably, and deformation recovery is rapid, when the rider when carrying out trample action, rider's shank produces downward pressure to seat portion, because binding layer has rigidity and toughness, the deformation that makes seat portion produce appropriateness, and after the application of force is cancelled, the quick reinstatement of steel disc, reduce the drag of seat portion to rider's leg, meet principle of human engineering, ride comfort is trampled laborsaving.

[primary clustering nomenclature]

12 backplate portions of 10 seat cushions, 11 seat portions, 13 nose seats

14 tailstocks, 20 elastic bows, 30 binding layers, 31 fibrages

32 thermoset layer, 33 thermoplastic layers

The specific embodiment

To shown in Figure 5, seat cushion 10 uses carbon fibre material to make overall profile, and surfacing as Fig. 1, and elastic bow 20 horizontal being arranged on the bicycle saddle tube of usefulness are supported in underrun.

Seat cushion 10 comprises a seat portion 11, takes for the rider provides, and side also is provided with terminal little curved backplate portion 12 downwards around the seat portion 11, with 11 enclosures of seat portion.The front edge of seat portion 11 bottom surfaces also is provided with nose seat 13, and rear end then neighbour is provided with tailstock 14, and nose seat 13 also has the relative slot of opening with tailstock 14.

One end of elastic bow 20 is plugged in the slot of nose seat 13, and the other end is inserted admittedly in the slot of tailstock 14, and elastic bow 20 can be crossed between nose seat 13 and the tailstock 14, and then seat cushion 10 can be located on the bicycle saddle tube for 20 groups by the elastic bow that supports usefulness.

Binding layer 30 is positioned at the bottom surface of seat portion 11, manufacturing process is: earlier fibrage is placed epoxy resin, after fibrage absorbs epoxy resin, the surface has microviscosity, and then use mould, one or more layers fibrage is arranged on the bottom surface of seat portion 11, and last, insert and put the thermoplasticity material between the following fibrage, utilize again that the mode of mould heat pressure is one-body molded to go out global shape, form binding layer 30, this binding layer 30 is by fibrage 31, thermoset layer 32 and thermoplastic layer 33 common be combined intos, wherein, the upper and lower surface of thermoplastic layer 33 all has fibrage 31 and

thermoset layer

32, and 10 surfaces of the seat cushion after the moulding still keep smooth form.

Like this, when on the rider is sitting in the seat cushion 10 of surfacing, trampling, because the binding layer 30 that the bottom surface of seat portion 11 has toughness, therefore can make the deformation of appropriateness, and after the application of force is removed, can reply fast, meet principle of human engineering, ride comfort is trampled laborsaving.

With reference to shown in Figure 6, be the cutaway view of the utility model preferred embodiment, in order to increase the deflection of seat cushion 10, also seat portion 11 is set to not wait with backplate portion 12 thickness, and seat portion 11 is slightly thinner than backplate portion 12.

In sum, key of the present utility model is, the binding layer 30 of seat portion 11 bottom surfaces is established a thermoplasticity material one by the fiber material folder that soaked epoxy resin and is subjected to the mould heat pressure moulding, and then when the rider trampled, rider's shank produced downward pressure to seat portion 11, because binding layer 30 has toughness, the deformation that makes seat portion 11 produce appropriateness, and after the application of force is removed, can reply fast, principle of human engineering met, ride comfort is trampled laborsaving.Previous embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to technological thought of the present utility model, any change of being done on the technical scheme basis all falls within the utility model protection domain.
