Abstract
The utility model discloses a snakelike spring shock absorber, and aims to overcome the defects that the saddle shock absorber of the present bicycle and the present electric motorcar is complicated in structure and can not realize shock absorption in the fore-and-aft direction. The snakelike spring shock absorber comprises a snakelike spring, a saddle connection tube and a saddle beam connection tube, and is characterized in that at least three U-shaped bending parts are arranged for the spring, and the radius of each U-shaped bending part is 12 mm; the saddle connection tube is welded at the middle part of the upper end of the spring, and the external diameter of the saddle connection tube is matched with the internal diameter of a saddle tube; and the saddle connection tube is welded at the middle part of the lower end of the spring, and the external diameter of the saddle beam connection tube is matched with the internal diameter of a saddle beam. The snakelike spring shock absorber is particularly applicable to shock absorption of the bicycle and the electric motorcar; and has the characteristics of simple structure and excellent shock absorption performance.
Description
Technical field
The utility model relates to a kind of bumper, relates in particular to a kind of serpentine spring bumper, is applicable to the damping of bicycle, electric motor car saddle.
Background technology
Bumper is mainly used to suppress concussion between attaching parts and from the impact of external force.Bicycle or shock absorbing device for electric vehicle can play the effect that improves the traveling comfort of riding.The bumper be applied in now on bicycle and battery-driven car has cylindrical spring bumper, leaf spring bumper, hydra-shock absorber, rubber absorbers, air-bag vibration damper.
These shock absorption devices all can play certain vertical damping effect, but some complex structures, and all can not effectively realize the damping of front and back position.
The utility model content
The utility model is the problem that overcomes above-mentioned shock absorption device, and a kind of serpentine spring bumper is provided, and has damping simple in structure, as can to realize front and back position.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of serpentine spring bumper, comprise serpentine spring, saddle connection pipe and saddle beam connection pipe; It is characterized in that: described spring is provided with at least 3 " U " shape curves, and the radius of described " U " shape curve is 12mm; Described saddle connection pipe is welded on the midway location in the spring upper end, and the overall diameter of described saddle connection pipe coordinates with the interior diameter of seatpillar; Described saddle beam connection pipe is welded on the midway location of spring lower end, and described saddle beam connection pipe overall diameter coordinates with saddle beam interior diameter.
Further, described spring adopts spring steel 55Si2MnB to make.
Use procedure of the present utility model is: by the saddle connection pipe, bumper is connected with saddle, by saddle beam connection pipe, bumper is connected with saddle beam (bicycle or electric vehicle body), " U " shape curve by spring carries out the damping of vertical direction and fore-and-aft direction.
Compared with prior art, the utlity model has following beneficial effect:
One, the utility model adopts serpentine spring, can realize the vertical direction of bicycle and battery-driven car, the damping of fore-and-aft direction, has improved damping performance, has strengthened the traveling comfort of riding.
Two, the utility model is arranged on bicycle or battery-driven car through saddle connection pipe and saddle beam connection pipe at serpentine spring, has characteristics simple in structure, easy for installation.
Three, spring of the present utility model adopts spring steel 55Si2MnB to make, and this spring steel quenching degree, comprehensive mechanical property, fatigue property are all for example, than spring steel commonly used (60Si2Mn) good, improve damping performance of the present utility model and service life.
Four, spring of the present utility model is made plate shape, is convenient to the installation of saddle connection pipe and saddle beam connection pipe, makes the characteristics easy for installation that the utlity model has.
Five, saddle connection pipe of the present utility model and saddle beam connection pipe all are arranged on the midway location of spring, make spring stress even, improve damping performance of the present utility model.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1 is spring, and 2 is the saddle connection pipe, and 3 is saddle beam connection pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model comprises serpentine spring, saddle connection pipe and saddle beam connection pipe; Preferably, spring is provided with 4 " U " shape curves, and the radius of " U " shape curve is 12mm; The saddle connection pipe is welded on the midway location of spring upper end, and the overall diameter of saddle connection pipe coordinates with the interior diameter of seatpillar, by the saddle connection pipe, with saddle, is connected; Saddle beam connection pipe is welded on the midway location of spring lower end, and saddle beam connection pipe overall diameter coordinates with saddle beam interior diameter, by saddle beam connection pipe, with bicycle or battery-driven car, is connected.
Spring of the present utility model adopts spring steel 55Si2MnB to make, and has quenching degree, comprehensive mechanical property, the good characteristics of fatigue property, improves damping effect of the present utility model and service life.Be plate shape by spring, be convenient to the installation of saddle connection pipe and saddle beam connection pipe; Chamfered is carried out in corner simultaneously, reduce concentrating of stress.
