Specific embodiment

Make concrete further instruction below in conjunction with the accompanying drawings to this utility model.A kind of novel children bicycle, which includes Vehicle frame 1, front fork 2 are turned to 3, and the front-wheel 4 on front fork 2, installed in the trailing wheel 5 at 1 rear of vehicle frame, is arranged in the middle part of vehicle frame 1 There are saddle 6 and foot-operated 7, it is characterised in that：Described vehicle frame 1 includes and turns to the conduit portion 11 3 installations, conduit portion 11 Two main supports 12 are rearward extended with, are connected by looped pipeline (13) in the middle part of two main supports, formed in " A " word moulding, main 12 tail end of frame is extended with forward two assistant supports 14, and assistant support 14 and main support 12 form " ＜ " word moulding, major and minor support 12, Excessively connected by 15 circular arc of back seat between 14, trailing wheel 5 is arranged on back seat 15；Lead between the front end of above-mentioned looped pipeline 13 and assistant support 14 Cross seatpillar 8 to connect.

Be provided with catching groove 16 on described looped pipeline 13, seatpillar 8 is interspersed to insert in the catching groove 16, the lower section of seatpillar 8 with 14 front end of assistant support is bolted and is integrated.

Gathering sill 17 is provided with described back seat 15, hind axle is arranged in the gathering sill.

Drawing code is provided with described gathering sill 17, is drawn code 18 to be sleeved on hind axle, trailing wheel is tensed backward.

Operation principle：In this case, the conduit portion 11 of body frame structure for automotive is extended with two main supports 12 in square divergent shape backward, Angle between two main supports is connected by looped pipeline 13 in the middle part of two main supports, is formed in " A " word in 10 ° to 25 ° angle distributions Moulding.Front fork is directly connected by main support with trailing wheel, and seatpillar is then arranged on looped pipeline, therefore the body weight of user is directly by leading Support undertakes.Wherein, as main support is integrated, therefore which can provide higher support force, it is to avoid conventional art Middle Split type welded support processing technique is complicated, the drawback such as bearing capacity difference.

Further：12 tail end of main support is extended with forward two assistant supports 14, and assistant support 14 is formed with main support 12 " ＜ " word moulding, assistant support front end are connected with seatpillar 8, therefore main support, assistant support and seatpillar three form gusseted Shape, further enhances the bearing capacity of this vehicle frame.In addition, the back seat 15 in this case is arranged on the connection of main support and assistant support Place, the overall round pie in fluting, back seat serve the intensity increasing action to main support and assistant support junction, meanwhile, by Have with main support and assistant support in back seat and be connected, therefore, trailing wheel can be supported simultaneously by major-minor support so that trailing wheel is more firm Reliably it is connected with vehicle body.

Compared with conventional art, in this case the unique moulding of main support while its support force is ensured, also so that this from Driving profile more fashion is novel, can fully lift the desire for consumer goods of user, so as to lift the market competitiveness, therefore extensively can push away It is wide to use.

Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model.
