Abstract

A spring blade comprises a first slice, a second slice and a third slice which are sequentially connected, wherein the second and third slices form a U-shaped structure; the first slice is turned over outwards from the upper end of the second slice and then extends downwards and outwards; at the same time, and an elastic blade extending towards the joint part between the second and third slices is further arranged on the second slice. The second and third slices of the spring blade cover the end of a base; the elastic blade on the second slice is clamped in a groove of the base to be fixed; and the first slice is propped against an external board. An oil tank cover with the spring blade is also provided. The spring blade is not only simple in structure and convenient to process, but also has an unchanged force point when the oil tank cover is opened and closed and is not deformed, so that the service life of the spring blade is prolonged.

Description

A kind of spring leaf and have the fuel lid of this spring leaf

Technical field

The utility model relates to a kind of spring leaf and has the fuel lid of this spring leaf, particularly a kind of spring leaf that is used for opening-closing structure.

Background technology

Current vehicle fuel tank cap is divided into manual unlocking and electronic release according to the mode difference of release.Electronic release is manually raised lid after being generally release, and manual unlocking then ejects automatically for the release rear cover body.Because manual unlocking is that the release rear cover body automatically springs open, so the essential device that needs a storage power of cap assembly of fuel tank flicks lid by the release that stores power after the release.At present, this device adopts spring leaf mostly, makes the spring leaf distortion by lid compression spring sheet when locking, and release rear spring sheet recovers to flick lid, and the fuel lid lid rotates around rotating shaft.But the general used spring leaf of fuel lid lid, when lid rotated around S. A., the stress point position of spring leaf changed, and caused period of service spring leaf distortion long afterwards, be difficult for closing when the plastic fuel tank cap body is closed, during unlatching sometimes lid can not eject.

Summary of the invention

Technical problem to be solved in the utility model is the spring leaf that a kind of simple in structure and reliability height, long service life are provided at above-mentioned prior art present situation, and the fuel lid with this spring leaf.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of spring leaf, it is characterized in that: comprise first section thin slice, second section thin slice and the 3rd section thin slice of linking to each other successively, wherein second section thin slice and the 3rd section thin slice form the U-shaped structure, described first section thin slice outwards turns down the back and stretches downwards and laterally from the upper end of described second section thin slice, on described second section thin slice, also have simultaneously towards the connecting portion of second section thin slice and the 3rd section thin slice extend flexure strip.This spring leaf is not only simple in structure, easy to process, and the structure of this spring leaf make to use the stress point of its fuel lid spring leaf when opening and closing can not change, and spring leaf can not produce distortion.

Preferably, for saving in material more and improve work efficiency, the flexure strip on described second section thin slice is the direct integral piece that forms of punching press from second section thin slice.

A kind of fuel lid with above-mentioned spring leaf, comprise fuel lid lid, pedestal and the outside plate that connects fuel lid lid and pedestal, wherein said outside plate external side end is installed on the described pedestal by rotating shaft, it is characterized in that: second section thin slice of described spring leaf and the 3rd section thin slice encase the end of described pedestal, and the flexure strip on second section thin slice is stuck in the groove of pedestal, and described first section thin slice is butted on the described outside plate.

Compared with prior art, advantage of the present utility model is that this chip architecture of the spring is simple, easy to process, and spring leaf adopts the Z font structure, therefore make the fuel lid lid when folding, can not change the stress point position of spring leaf, use long afterwards spring leaf also can not produce distortion and cause the folding of fuel lid to have some setbacks.

Description of drawings

Fig. 1 is the structural representation of the spring leaf of the utility model embodiment.

Fig. 2 is that the spring leaf of the utility model embodiment is at the structural application scheme drawing of fuel lid.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Spring leaf of the present utility model, shown in Fig. 1-2, by three sections successively the bonded assembly thin slice form, these three sections thin slices are respectively first section thin slice 11, second section thin slice 12 and the 3rd section thin slice 13, wherein second section thin slice 12 connects first section thin slice 11 and the 3rd section thin slices 13.Second section thin slice 12 and the 3rd section thin slice 13 form a U-shaped structure, described first section thin slice 11 outwards turns down the back and stretches downwards and laterally from the upper end of second section thin slice 12 of this U-shaped structure, on described second section thin slice 12, also have simultaneously towards the connecting portion of second section thin slice 12 and the 3rd section thin slice 13 extend flexure strip 121.This flexure strip 121 is direct integral pieces of forming of punching press from this second section thin slice 12, therefore saving in material easy to process, need not be in addition welding assembly again.

As shown in Figure 2, fuel lid with this spring leaf 1 comprises fuel lid lid 3, pedestal 2 and the outside plate 31 that connects fuel lid lid 3 and pedestal 2, described outside plate 31 can be an integrated injection molding spare with fuel lid lid 3, when this spring leaf 1 is installed, wherein second section thin slice 12 and the 3rd section thin slice 13 encase an end of pedestal 2, and the flexure strip 121 of second section thin slice 12 of spring leaf 1 matches with pedestal 2, the groove 21 that snaps in pedestal 2 is interior to fix this spring leaf 1 and pedestal 2, first section thin slice 11 of this spring leaf 1 is butted on the outside plate 31 of fuel lid 3, and fuel lid lid 3 is hinged by outside plate 31 and pedestal 2 and can be around the oil rotating shaft rotation of case lid 3 of pedestal 2.First section thin slice 11 of this spring leaf 1 just is against applies an outside elastic force on the outside plate 31 this outside plate 31, when fuel lid 3 was closed, 1 energy storage of outside plate 31 extrusion spring sheets was when fuel lid 3 is opened, spring leaf 1 is just given 31 1 elastic force of this outside plate, makes outside plate 31 to open rapidly.

This spring leaf 1 adopts the structure of three foldings, volume is less, and when fuel lid 3 opens and closes and the mutual alignment between outside plate 31 and the pedestal 2 can not change, therefore can not produce problem because of long rear spring sheet 1 distortion of period of service, and then also can be because of causing fuel lid to be difficult for the problem of opening and closing after the period of service length.
