Abstract
Provided is a convenient folding bicycle frame, which is characterized in that a front bicycle frame (3) is provided with an inclined shaft sleeve (10) capable of changing a turning direction; the inclined shaft sleeve (10) is movably connected to an arc-shaped distortion rack (13) on a rear bicycle frame (16). The convenient folding bicycle frame is advantageous in that a bicycle or an electric bicycle assembled by the bicycle frame has a much smaller size when being folded than an unfolded bicycle of the same type; operation is very simple and structure is very safe and reliable; producing cost is very low and weight is light.
Description
Affiliated technical field:
The utility model relates to folding bicycle, folding electric bicycle, for the development of bicycle provides special innovation.
Background technology:
Present known folding bicycle kind is a lot of, and it is folding that great majority are difficult to operation, and it is bigger perhaps to fold up volume, and practical function and durability are relatively poor, and more incompatible travelling goes out to carry.
Summary of the invention:
The purpose of the utility model is to provide a kind of " bicycle makes things convenient for folding stand "; Fold up little a lot of of volume than same wheel model; And operation is very easy, and structure is as safe as a house reliable, and this vehicle frame also can easily be assembled into Electrical Bicycle.
The design plan of the utility model is: design a kind of front vehicle frame (3) and back vehicle frame (16); It is characterized in that front vehicle frame (3) is provided with the inclined shaft cover (10) that can change the turnover direction, go up a kind of arc distortion of design support (13), flexibly connect with inclined shaft cover (10) at back vehicle frame (16); The strong point (9) that in front vehicle frame (3), is provided with simultaneously elasticity original paper (7) and back vehicle frame (16) support that mutually combines.
When being assembled into car load: front wheel spindle (4) and hind axle (19) are in parastate; But when folding: arc distortion support (13) is just along the gradient axial rotation of inclined shaft cover (10); Make hind axle (19) and front wheel spindle (4) produce axial offset; Then the rear wheel (17) on the back vehicle frame (16) is closed to front vehicle wheel (1), at this moment saddle (5) and seatpillar (6) are inserted on the vehicle frame seat pipe (12), and seatpillar (6) also bumps less than front vehicle frame (3) again; Be folded down handlebar (2) again, just car load folded into very little state.If during the assembling Electrical Bicycle, only need upward to close (11) and control apparatus (15) by packed battery at back vehicle frame (16), refill wheel hub motor (18) and get final product.
Beneficial effect:
The utility model is with technical pattern very cleverly, durable method of application as safe as a house, and very cheap manufacturing cost has realized method for folding and portable practical function that bicycle and Electrical Bicycle are very light.
Description of drawings
Fig. 1 is the structural principle scheme drawing of the utility model;
Fig. 2 is the scheme drawing of the utility model after folding;
Fig. 3 be the A of the utility model to scheme drawing, (inclined shaft cover (10) and arc distortion support (13) bonded assembly enlarged diagram).
The specific embodiment:
The implementation method of the utility model is described: become front vehicle frame (3) and back vehicle frame (16) with steel pipe manufacturing, go up in front vehicle frame (3) and be welded into inclined shaft cover (10) by design point of view below in conjunction with accompanying drawing; Be made into arc distortion support (13) by design point of view in addition, and be fixedly welded on the pedal spindle bearing (14) of back vehicle frame (16).Again arc being twisted support (13) and inclined shaft cover (10) uses lock bolt (8) is tied; Pack in the front vehicle frame (3) as elasticity original paper (7) in addition with poly-urethane rubber; The strong point (9) support that mutually combines with back vehicle frame (16) promptly forms the utility model " bicycle makes things convenient for folding stand ".
