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 technical field of battery-driven car parts, be specially a kind of supporting tube structure of electric foldable power-assistant bicycle.
Background technology
support tube is to support on folded bicycle, the fixing head of support saddle pipe, see Fig. 1, the supporting tube structure of existing bicycle comprises the lock bracket 1 that is flexibly connected with the support saddle pipe, be flexibly connected the lockplate 2 of lock bracket, support tube 5, pass through adjusting screw(rod) 3 and setting nut 4-1 between support tube 5 and lock bracket 1, 4-2 connects, existing support tube connecting portion is too much, the machined part stack assembling of a lot of dimensional fits, cause quality state to control very difficult, be unfavorable for batch manufacturing, and in use due to the restriction of angle of assembling, during longitudinal stress, each related parts can be out of shape, straightness accuracy and the strength of material of support tube have been affected, have potential safety hazard.
Summary of the invention
For the problems referred to above, the invention provides a kind of supporting tube structure of electric foldable power-assistant bicycle, can improve the relative straightness accuracy after each parts of support tube make up, the opposing parallel that effectively solves support saddle pipe and support tube is improved structural strength, the reliability of service of support tube under angle is stressed.
Its technical scheme is such: a kind of supporting tube structure of electric foldable power-assistant bicycle, it comprises lock bracket, lockplate, support tube, described lockplate is flexibly connected described lock bracket by torsion spring, it is characterized in that: support tube connects described lock bracket by the support tube endoporus with bolt.
It is further characterized in that: be provided with spring in described support tube, support tube endoporus bolt is pressed on the top, upper end of spring, and 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 described support tube, support tube endoporus bolt is pressed on the top, upper end of described spring, and the lower end of described spring is provided with wear-resistant pad.
In said structure of the present invention, bolt directly connects described lock bracket by described support tube endoporus, improved the relative straightness accuracy after each parts of support tube make up, the opposing parallel that effectively solves support saddle pipe and support tube is improved structural strength, the reliability of service of support tube under angle is stressed.
