Abstract

A passenger car trunk hinge mechanism is provided. The utility model is provided with two pairs of hinges which are separately arranged on a trunk cover and a car body for connecting the left side and the right side. Wherein, each pair of hinge comprises of a hinge connecting arm, a hinge lever arm, a torsion-bar spring and a permanent seat. The permanent seat is fixed on the car body, one side of the hinge lever arm is connected with the permanent seat by a pin thereby forming a rotation pair, another side of the hinge lever arm is fixed on an inner board of the trunk cover by a bolt, two corners are provided on the torsion-bar spring whose one corner is hanged on the permanent seat and another corner is hanged on the hinge connecting arm, another side of a torsion bar is connected with the permanent seat of another pair of hinges. The hinge mechanism can be opened to an optional position by the torsion spring in the opening range of the trunk cover whereby ensuring that the trunk cover has an enough opening and does not interfere with other parts of the car body during the opening process, which lightly and flexibly opens and closes the cover and has an enough intensity and rigidity as well as a correct movement and is reliable and perdurable.

Description

Passenger car Hinge of Trunk Lid mechanism

Technical field

The utility model relates to a kind of linkage.

Background technology

At present, the hinge of passenger car luggage-boot lid has single-point type hinge and two kinds of forms of chain link formula hinge.It is simple in structure for the single-point type hinge, and cost is low, but center of rotation is fixed when opening, and therefore, set out the hinge center in the front end front side, in case collide with other member when opening, has moulding to retrain to the luggage case front and back end.The characteristics of chain link formula hinge are center of rotation for movably, and the moulding degree of freedom of front and back end is big.But, different because of the hinge geometry design, the initial stage load when opening probably can increase, and luggage-boot lid is sunk.

Summary of the invention

The purpose of this utility model is the deficiency that exists at prior art, proposes a kind of passenger car Hinge of Trunk Lid mechanism, to guarantee the opening and closing luggage-boot lid light and flexible, prevents that lid when latch hook is thrown off from raising and opening the situation that the initial stage luggage-boot lid sinks automatically and taking place.

The technical solution of the utility model is as follows:

A kind of car runk linkage, it has two secondary hinges, is installed in luggage-boot lid respectively and is connected the right and left with vehicle body.Wherein every secondary hinge is made of hinge linking arm, hinge lever arm, torsion-bar spring and holder, holder is fixed on the vehicle body, hinge lever arm one end is connected by pin with holder, the two forms a revolute, the hinge lever arm other end is by being bolted on the boot-lid inner panel, and an end of torsion-bar spring has two turnings, and a turning hangs on the holder, another turning hangs on the hinge linking arm, and the other end of torsion-bar spring then is connected on the holder of another secondary hinge.

This linkage makes luggage-boot lid pass through this mechanism to link to each other with vehicle body, and around the rotation of hinge center of rotation, and under luggage-boot lid was in closed condition, torsion bar was in lower fulcrum position, and torsion bar distortion this moment will produce a rock deformation pressure; After luggage case was unlocked, luggage-boot lid was opened under the effect of torsion-bar spring deformation force.

Advantage of the present utility model is as follows:

1, this linkage can be in luggage-boot lid aperture scope, and the effect by torque spring is opened to the optional position, can guarantee that luggage case is stamped enough apertures, and does not interfere with other positions of vehicle body in opening process.

2, open-close lid light and flexible: because of having adopted balancing spring chain link formula hinge, the characteristic of balancing spring makes the luggage-boot lid gravitational moment that spring force can balance luggage case lid when fastening position, make the unlikely sinking of unlatching initial stage luggage-boot lid, and when lid is opened into maximum position, spring force should be slightly larger than the needed power of quality of balance lid, alleviate greatly and think the effect of external force, satisfy the instructions for use of hommization.

3, enough strength and stiffness are arranged, to guarantee that motion is correct, reliable durable.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of torsion-bar spring wherein.

The specific embodiment

This linkage is made of two secondary hinges, is installed in luggage-boot lid respectively and is connected the right and left with vehicle body.Referring to Fig. 1, shown the mounting structure figure of a secondary hinge among the figure, another pair symmetry is with it installed, and structure is identical, so do not provide among the figure.Every secondary hinge all is made of hinge linking arm 4, hinge lever arm 3, torsion-bar spring 5 and holder 6, holder 6 is by being bolted on the vehicle body 1, hinge lever arm 3 one ends and holder 6 are connected by pin, the two forms a revolute, and hinge lever arm 3 other ends are by being bolted on the boot-lid inner panel 2.The structure of torsion-bar spring 5 is referring to Fig. 2, its end has two turning A and B, a turning A hangs on the holder 6, another turning B hangs on the hinge linking arm 4, the other end C of torsion-bar spring then is connected on the holder of another secondary hinge, so just hinge lever arm 3, hinge linking arm 4, torsion-bar spring 5 and holder 6 are formed simple quadric chain thus, reach the purpose of steady opening and closing luggage-boot lid.

Claims

1, a kind of passenger car Hinge of Trunk Lid mechanism, it has two secondary hinges, be installed in luggage-boot lid respectively and be connected the right and left with vehicle body, it is characterized in that: every secondary hinge is by the hinge linking arm, the hinge lever arm, torsion-bar spring and holder constitute, holder is fixed on the vehicle body, hinge lever arm one end is connected by pin with holder, the two forms a revolute, the hinge lever arm other end is by being bolted on the boot-lid inner panel, one end of torsion-bar spring has two turnings, a turning hangs on the holder, and another turning hangs on the hinge linking arm, and the other end of torsion-bar spring then is connected on the holder of another secondary hinge.
