Abstract
In a spring rod supporting and moving combined bicycle frame, the bicycle frame is divided into a back bicycle frame and a front bicycle frame with a seat tube as a boundary. The back bicycle frame is still in a fixed triangular structure; and in the front bicycle frame, the spring supporting rod, a seat tube and a lower beam are connected via three rotating shafts to form a dynamic triangular structure, so a design concept of a traditional bicycle frame is changed. The spring rod supporting and moving combined bicycle frame is advantageous in that material can be saved to the largest extent, so bicycle weight is reduced and rigidity and stability of a bicycle body are enhanced; damages to each structure of the bicycle frame due to impact are reduced; and driving comfortableness can be improved.
Description
Technical field
Spring bar supports, moves in conjunction with cycle frame, is a kind of cycle frame with dynamic structure.
Background technology
Bicycle be walking-replacing tool be also sports equipment, in recent years due to continuous technological advance, all there are great changes in bicycle in material, structure, type of drive; Traditional bicycle rack is to adopt fixed type three-legged structure mostly, also have and use twin beams or single-beam instead, the present tube portion of some BMX (Bicycle Motocross) has added spring, it is much of that side arm just becomes moving knot, also reached the object of damping, but the moment of front-axle beam still concentrates on single-beam, improve stability, with regard to bad saving material, facts have proved, three-legged structure is only the version that realizes best mechanical characteristics, preferably safety, saves material most; The utility model is to provide a kind of spring bar and supports, moves in conjunction with cycle frame.
Summary of the invention
The utility model is achieved in that take seat pipe as boundary, and vehicle frame is divided into rear vehicle frame and two parts of front vehicle frame, and rear vehicle frame region is comparatively compact, is a little trigonum, still continues to use traditional fixed type three-legged structure; The underbeam of front vehicle frame be an entirety vertical being understood as, then one of underbeam position that is connected to middle beam barrel with rotating shaft, as long as the intensity of underbeam can guarantee to add the car body safety of riding after load just passable.Then the position of the Seat stay of rear vehicle frame and the handing-over of seat pipe with being connected, installing a spring supporting bar with rotating shaft between standing, spring supporting bar is with pneumatic spring additional mechanical spring or adopt the spring supporting bar of mechanical spring completely, so just form a dynamic trigonum by underbeam, seat pipe and spring supporting bar, Here it is said spring supporting bar, moving in conjunction with cycle frame.
The one longitudinal folding snap close with folding shaft is set on underbeam, unties the rotating shaft on spring supporting bar,, then open folding snap close, car body just can be realized longitudinal folding like this.
This structure can realize saving frame materials to greatest extent, thereby alleviate car body weight, the auxiliary underbeam of spring supporting bar improves intensity and load-carrying capacity, also can alleviate because impact the destruction of causing to the each system point of vehicle frame, improved the traveling comfort while riding, carrying and place also all can be more convenient than traditional vehicle frame simultaneously.
Accompanying drawing explanation
Fig. 1 is spring supporting bar, moving in conjunction with cycle frame schematic diagram.
Specific embodiments
As shown in the figure, as boundary, vehicle frame is divided into rear vehicle frame and two parts of front vehicle frame take seat pipe (1), rear vehicle frame is little trigonum, still continues to use traditional fixed type three-legged structure; An entirety the underbeam of front vehicle frame (2) with vertical (4) are understood, again one of underbeam (2) position that is connected to middle beam barrel (10) with rotating shaft (3), then the delivery position of the Seat stay (6) of rear vehicle frame and seat pipe (1) with vertical (4) between use rotating shaft (7,8) to link, install a spring supporting bar (5), spring supporting bar (5) is with pneumatic spring additional mechanical spring or adopts the spring supporting bar of mechanical spring completely; The dynamic trigonum being made up of underbeam (2), seat pipe (1) and spring supporting bar (5) and rotating shaft (3,7,8), be exactly said spring supporting bar, moving in conjunction with cycle frame.
The one longitudinal folding snap close (9) with folding shaft is set on underbeam (2), when untiing rotating shaft (8) on spring supporting bar (5), opening folding snap close (9) again, vehicle frame just can be realized longitudinal folding.
Claims (2)
1. spring supporting bar, moving in conjunction with cycle frame, is characterized in that: take seat pipe (1) as boundary, vehicle frame is divided into rear vehicle frame and front vehicle frame; The underbeam (2) of front vehicle frame is an entirety with vertical (4), one of underbeam (2) position that is connected to middle beam barrel (10) with rotating shaft (3), then the Seat stay (6) of rear vehicle frame and seat pipe (1) delivery position with vertical (4) between use that rotating shaft (7,8) links, mounting spring strut bar (5), spring supporting bar (5) is with pneumatic spring additional mechanical spring or adopt mechanical spring completely.
2. according to the said spring supporting bar of claim 1, moving in conjunction with cycle frame, it is characterized in that: a longitudinal folding snap close (9) with folding shaft is set on underbeam (2).
