The utility model content
The purpose of the utility model provides a kind of unlatching labour-saving car boot cover linkage.
The technical scheme that the utility model provided is following: a kind of car boot cover linkage; Constitute by first connecting rod (1), second connecting rod (2), third connecting rod (3) and the 4th connecting rod (4); The left end of said first connecting rod (1) is through the lower ends of first pin joint (A) with the 4th connecting rod (4); The right-hand member of first connecting rod (1) is through the lower ends of second pin joint (B) with second connecting rod (2); The upper end of second connecting rod (2) is through the lower ends of the 3rd pin joint (C) with third connecting rod (3); The upper end of the 4th connecting rod (4) is through the lower ends of the 4th pin joint (D) with third connecting rod (3); And the 4th pin joint (D) is positioned at the top of the 3rd pin joint (C), and the left end of said first connecting rod (1) is provided with the first pneumatic strut mounting points (I), and the middle part of said third connecting rod (3) is provided with the second pneumatic strut mounting points (II); Key is: when baggage compartment lid hinge mechanism closed, the extended line of the line of the said first pneumatic strut mounting points (I) and the second pneumatic strut mounting points (II) was positioned at the top of the 4th pin joint (D).
When baggage compartment lid hinge mechanism opened, the angle of the line of the line of said first pin joint (A) and second pin joint (B) and second pin joint (B) and the 3rd pin joint (C) was 115 °.Guarantee the enough big opening angle of luggage-boot lid, rainwater flows in the luggage case in the time of effectively preventing deck-lid release, avoids the article in the luggage-boot lid to be drenched by rainwater.
Be preferably; Said first pin joint (A) is 146.5mm with the distance of second pin joint (B); Second pin joint (B) is 136.0mm with the distance of the 3rd pin joint (C); The 3rd pin joint (C) is 28.7mm with the distance of the 4th pin joint (D), and the 4th pin joint (D) is 261.8mm with the distance of first pin joint (A).The size of linkage rationally, be of moderate size, be convenient to install.
The power that pneumatic strut acts on third connecting rod is exactly the power that pneumatic strut acts on luggage-boot lid; The direction of rotation of third connecting rod is exactly the direction of rotation of luggage-boot lid; When the utility model is opened through the adjustment hinge; The direction of power that pneumatic strut acts on third connecting rod is consistent with the direction of rotation that makes third connecting rod, thereby makes pneumatic strut more laborsaving when opening luggage-boot lid.Beneficial effect: reasonable in design, easy to implement, it is easily laborsaving to open luggage-boot lid.
