Abstract
The utility model relates to a rotating shaft structure of a vibration damping frame for an electric motorcar, which comprises a rotating shaft connecting plate, a bottom fork connecting plate and fastening bolts; notches of the rotating shaft connecting plate and the bottom fork connecting plate are oppositely inserted; the bottom fork connecting plate is inserted into the rotating shaft connecting plate; the fastening bolts are symmetrically mounted at two contact ends of the rotating shaft connecting plate and the bottom fork connecting plate; the fastening bolts and the bottom fork connecting plate are fixedly mounted in a meshing manner; and the rotating shaft connecting plate and the bottom fork connecting plate realize the relative swinging rotation. The utility model utilizes the bottom fork connecting plate to replace a rotating shaft, and the two contact ends are mounted through the fastening bolts, so that the low-angle swinging rotation of the rotating shaft connecting plate and the bottom fork connecting plate is realized, the integral structure is simple, the manufacture and installation are easy, and the cost is low.
Description
Technical field
The utility model belongs to electric automobiles, especially a kind of battery-driven car frame for reducing vibration pivot structure.
Background technology
Battery-driven car is to use the comparatively general vehicle at present, for people's loading shopping provides great convenience.Owing to be driven by power, and speed is very fast, therefore existing battery-driven car common design vibration-proof structure, also designed vibration damping bonded assembly structure as preceding triangular frame by being connected between the chain stay connecting panel of rotating shaft connecting panel and Vee formation vehicle frame, its concrete structure is: adopt a hinge to install between rotating shaft connecting panel and the chain stay connecting panel, this hinge is made of overcoat and coaxial interior cover, interior cover installs by tie bolt with the rotating shaft connecting panel, overcoat and chain stay connecting panel install, and coaxial package has a vibration damping cover by the rubber making between interior cover and overcoat.The shortcoming of this version is: 1, hinge is in installation process, and the vibration damping cover is distorted easily and is out of shape even breakage, thereby making to flexibly connect to change into is rigidly connected, and loses damping of vibrations; 2, because battery-driven car has all designed damper spring, as long as rotating shaft connecting panel and chain stay connecting panel can be realized the low-angle rotation, so the effect of vibration damping cover is not obvious; 3, existing hinge structure is comparatively complicated, and installation, maintenance, cost are all higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, with low cost, easy battery-driven car frame for reducing vibration pivot structure of installation and maintenance is provided.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of battery-driven car frame for reducing vibration pivot structure, constitute by rotating shaft connecting panel, chain stay connecting panel and binding bolt, rotating shaft connecting panel and the relative setting-in of chain stay connecting panel notch, chain stay connecting panel setting-in is gone within the rotating shaft connecting panel, rotating shaft connecting panel and the contacted two ends of chain stay connecting panel are symmetrically installed with binding bolt, this binding bolt and the engagement of chain stay connecting panel install the relative rotation with the chain stay connecting panel of rotating shaft connecting panel.
And, the concrete structure that the contacted two ends of described rotating shaft connecting panel and chain stay connecting panel symmetry adopts binding bolt to install is: symmetry is shaped on through hole on the rotating shaft connecting panel, suit one axle sleeve in this through hole, the length of this axle sleeve is greater than the wall thickness of rotating shaft connecting panel, suit binding bolt in this axle sleeve.
And, flat gasket and spring washer are installed on binding bolt.
Advantage of the present utility model and beneficial effect are:
1, this frame shaft structure adopts the chain stay connecting panel to substitute axle, and two ends adopt binding bolt to install, and have realized the low-angle rotation of rotating shaft connecting panel and chain stay connecting panel, and integral structure is simple, makes and installs easily, and is with low cost.
2, this frame shaft structure adopts the mode of the length of axle sleeve greater than the wall thickness of rotating shaft connecting panel, after binding bolt is fastening, still can realize rotation between rotating shaft connecting panel and the chain stay connecting panel, is skillfully constructed, and is economical and practical.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the cross-sectional view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of battery-driven car frame for reducing vibration pivot structure, by rotating shaft connecting panel 1, chain stay connecting panel 2 and binding bolt 3 constitute, the back side of rotating shaft connecting panel and preceding triangular frame (not illustrating in the accompanying drawing) welding install, the back side of chain stay connecting panel and Vee formation vehicle frame (not illustrating in the accompanying drawing) welding install, rotating shaft connecting panel and the relative setting-in of chain stay connecting panel notch, and chain stay connecting panel setting-in is gone within the rotating shaft connecting panel, the two contacted two ends symmetry adopts binding bolt to install, concrete structure is: symmetry is shaped on through hole on the rotating shaft connecting panel, suit one axle sleeve 4 in this through hole, the length of this axle sleeve is greater than the wall thickness of rotating shaft connecting panel; Suit binding bolt in this axle sleeve, the front end of this binding bolt and the engagement of chain stay connecting panel install.
In order to realize the reliability that installs of binding bolt, on the nut of binding bolt and the binding bolt between the rotating shaft connecting panel, be set with flat gasket 5 and spring washer 6.
Principle of work of the present utility model is:
Binding bolt installs into installing in the axle sleeve and with the chain stay connecting panel engagement of the inside, because the length of axle sleeve is greater than the wall thickness of rotating shaft connecting panel, therefore binding bolt diametrically can't the fixed rotating shaft connecting panel, has realized the relative rotation of rotating shaft connecting panel with the chain stay connecting panel.
Claims (3)
1, a kind of battery-driven car frame for reducing vibration pivot structure, it is characterized in that: constitute by rotating shaft connecting panel, chain stay connecting panel and binding bolt, rotating shaft connecting panel and the relative setting-in of chain stay connecting panel notch, chain stay connecting panel setting-in is gone within the rotating shaft connecting panel, rotating shaft connecting panel and the contacted two ends of chain stay connecting panel are symmetrically installed with binding bolt, this binding bolt and the engagement of chain stay connecting panel install the relative rotation with the chain stay connecting panel of rotating shaft connecting panel.
2, battery-driven car frame for reducing vibration pivot structure according to claim 1, it is characterized in that: the concrete structure that the contacted two ends of described rotating shaft connecting panel and chain stay connecting panel symmetry adopts binding bolt to install is: symmetry is shaped on through hole on the rotating shaft connecting panel, suit one axle sleeve in this through hole, the length of this axle sleeve is greater than the wall thickness of rotating shaft connecting panel, suit binding bolt in this axle sleeve.
