Abstract
The utility model discloses a bicycle frame, which comprises an upper tube, a middle tube, a back upper fork and a back lower fork, wherein the back upper fork is connected with the back fork by a back fork sheet; the back fork sheet is arranged in a triangular shape and provided with a fork opening adaptive to a back wheel cross shaft; and two edges of the back fork sheet are basically tangential to the back upper fork and the back lower fork respectively. According to the utility model, the weight of the frame can be reduced, so that the bicycle can be suitable for various users and places and the frame can be also more beautiful and elegant.
Description
Technical field
The utility model relates to the bicycle field, particularly relates to a kind of bicycle frame.
Background technology
Vehicle frame is the vitals of bicycle, and it comprises front triangle and Vee formation etc., and front triangle is made of parts such as head tube, upper pipe and middle pipes, and Vee formation is by Seat stay and Chain stay etc.In the prior art, the Seat stay of vehicle frame is connected the back vent sheet and connects with Chain stay, and this back vent sheet profile is larger, and weight is heavier, and user's experience sense is relatively poor, and can not be suitable for multiple user.In addition, to requiring the occasion of weight light (for example performance), the vehicle frame of this structure obviously can not meet the demands at some.
The utility model content
Main purpose of the present utility model is to provide a kind of cycle frame, is intended to effectively solve the heavier technical matters of vehicle frame weight in the prior art.
In order to realize the utility model purpose, the utility model provides a kind of cycle frame, comprise pipe, middle pipe, Seat stay and Chain stay, wherein, described Seat stay and Chain stay link together by the back vent sheet, the setting triangular in shape of described back vent sheet, it is provided with the prong suitable with rear wheel lateral axle, and two limits of described back vent sheet are substantially tangent with described Seat stay and Chain stay respectively.
Preferably, described Seat stay is set up on described pipe and middle pipe by welding.
Preferably, described Seat stay is provided with interior concave arc near an end of described middle pipe.
Cycle frame in the utility model, two limits of its back vent sheet and described Seat stay and Chain stay are tangent respectively, so the small volume of back vent sheet, and weight is lighter, so that bicycle can be suitable for multiple user and occasion.In addition, Seat stay is set up on described pipe and middle pipe by welding, so that vehicle frame is more elegant in appearance.
Description of drawings
Fig. 1 be among the utility model one embodiment cycle frame face structural representation;
Fig. 2 is the structural representation of Seat stay in the cycle frame among the utility model one embodiment.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See figures.1.and.2, propose the utility model cycle frame one embodiment.Among the utility model embodiment, cycle frame comprises pipe 10, middle pipe 20, Seat stay 30 and Chain stay 40.Seat stay 30 links together by back vent sheet 50 with Chain stay 40.Described back vent sheet 50 settings triangular in shape, it is provided with the prong 51 suitable with rear wheel lateral axle, and two limits 52,53 of described back vent sheet 50 are substantially tangent with described Seat stay 30 and Chain stay 40 respectively.
Among the utility model embodiment, because two limits 52,53 of back vent sheet 50 are substantially tangent with described Seat stay 30 and Chain stay 40 respectively, so the small volume of back vent sheet 50, weight is lighter, so that bicycle can be suitable for multiple user and occasion.
With reference to shown in Figure 1, described Seat stay 50 is set up on described pipe 10 and middle pipe 20 by welding.Because Seat stay 50 is set up on described pipe 10 and middle pipe 20 by welding, and is so that whole vehicle frame profile is succinct, more elegant in appearance.
As shown in Figure 2, among the utility model one embodiment, Seat stay 30 is provided with interior concave arc 31 near an end of described middle pipe 20.Should can pass through the mould bending moulding by interior concave arc 31.Owing to be provided with interior concave arc 31, be stream line pattern between Seat stay 30 and the front triangle, profile is more elegant in appearance.
It below only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
