Abstract
The invention provides a supporting tube structure of a folding type electric power assistant bicycle, capable of improving relative straightness after combination of all parts of the supporting tube, effectively solving relative parallelism between a middle support saddle tube and the supporting tube, and improving structural strength and use reliability of the supporting tube under an angular stress. The supporting tube structure comprises a locking bracket, a locking plate and the supporting tube, wherein the locking plate is movably connected with the locking bracket through a torsional spring. The supporting tube structure is characterized in that the supporting tube is connected with the locking bracket by bolts through a supporting tube inner hole.
Description
Technical field
The present invention relates to the battery-driven car technical field of parts and components, be specially a kind of support tube structure of Foldable electric morpet.
Background technology
Support tube on folded bicycle be support, the fixing head of support saddle pipe, see Fig. 1, lockplate 2, the support tube 5 of the lock bracket 1 that the support tube structure of existing bicycle comprises and the support saddle pipe flexibly connects, flexible connection lock bracket; Be connected with setting nut 4-1,4-2 through adjusting screw(rod) 3 between support tube 5 and the lock bracket 1; Existing support tube connecting portion is too much, and the machined part stack assembling that a lot of sizes cooperate causes very difficulty of quality state control; Be unfavorable for batch manufacturing; And in use owing to the restriction of angle of assembling, during longitudinal stress, each related parts can be out of shape; Influence the straightness accuracy and the strength of material of support tube, had potential safety hazard.
Summary of the invention
To the problems referred to above; The invention provides a kind of support tube structure of Foldable electric morpet; Can improve the relative straightness accuracy after each parts of support tube make up, the opposing parallel that solves support saddle pipe and support tube is effectively improved structural strength, the reliability of service of support tube under angle is stressed.
Its technical scheme is such: a kind of support tube structure of Foldable electric morpet; It comprises lock bracket, lockplate, support tube; Said lockplate flexibly connects said lock bracket through torsion spring, it is characterized in that: support tube is through the said lock bracket of support tube endoporus bolt together.
It is further characterized in that: be provided with spring in the said support tube; The upper end roof pressure support tube endoporus bolt of spring, the lower end of spring press-fits in limiting stopper, and the bottom of limiting stopper press-fits in bearing; Bearing carrier ring is loaded on pivot shaft, and the two ends of pivot shaft are installed on the kidney slot of support tube lower end tube wall; Be provided with spring in the said support tube, the upper end roof pressure support tube endoporus bolt of said spring, the lower end of said spring is provided with wear-resistant pad.
In the said structure of the present invention; Bolt is through the said lock bracket of said support tube endoporus direct connection; Improved the relative straightness accuracy after each parts of support tube make up, the opposing parallel that solves support saddle pipe and support tube is effectively improved structural strength, the reliability of service of support tube under angle is stressed.
