 The present invention mainly relates to a trunk lid lifting device for assisting an opening operation when unlocking a trunk lid on a trunk room at a rear part of an automobile.

[0002]

[Prior Art]

 As shown in FIG. 6 and FIG. 7, there is a trunk room 2 at the rear of the vehicle body 1 of an automobile, and a trunk lid 3 for covering the upper surface thereof is rotatably mounted vertically via a pair of left and right hinges 4. The trunk lid 3 can be flipped up and opened by unlocking the latch mechanism 5 provided at the rear part so as to be separated from the lower striker 6.

A pair of right and left gas springs 7 are provided as a trunk lid push-up device for assisting the opening operation when the trunk lid 3 is unlocked. One end of each of these gas springs 7 is pivotally attached to the upper portion of the quarter panel 1a at the upper edge of the trunk room 2 of the vehicle body 1 through a pivot pin 8 so as to be rotatable in the up and down direction, and the other end is attached to the back surface of the trunk lid 3. It is attached to the protruding bracket 9 via a pivot pin 10 so as to be rotatable.

When the trunk lid 3 is unlocked by latching and opened upward, the gas spring 7 interlocks with the trunk lid 3 and rises from the substantially horizontal state shown by the phantom line in FIG. The gas spring 7 exerts an urging force by a reaction force to assist the upward opening operation of the trunk lid 3 and support the upward opening state of the trunk lid 3.

[0005]

[Problems to be solved by the device]

 By the way, in the conventional trunk lid lifting device described above, when the trunk lid 3 is fully closed, the gas spring 7 falls down substantially parallel to the back surface of the trunk lid 3. Therefore, the biasing force due to the reaction force of the gas spring 7 is applied to the trunk lid 3. Even if the trunk lid 3 is latched and unlocked from the fully closed state by only acting in a direction substantially orthogonal to the opening direction of the lid 3, the trunk lid 3 is only slightly lifted by the biasing force of the gas spring 7. Absent. For this reason, it is difficult to determine whether or not the latch of the trunk lid 3 is unlocked, and there is a small gap under the trunk lid 3, which makes it inconvenient for a person to put a finger in for opening operation.

The present invention has been made in view of the above circumstances. The purpose of the present invention is to add a simple improvement so that the fully closed trunk lid can be appropriately opened by unlocking the gas spring. It is possible to automatically lift up to the height, it is easy to determine whether or not the trunk lid is unlocked, and it is easy to put your finger under the trunk lid, which makes it easier to open the trunk lid. It is to provide a simple trunk lid lifting device.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the trunk lid lifting device of the present invention is provided with a gas spring with one end rotatably pivoted to the vehicle side, while the upper end of the trunk lid is pivoted through a pivot pin. An elbow tension lever is provided that is movably pivotally attached and that when the trunk lid is closed, the lower part abuts against the vehicle body surface and tilts while sliding forward. The other end of the gas spring is located at an intermediate position in the vertical direction of the lever. When the trunk lid is unlocked, the lever is erected and rotated by the moment around the pivot pin due to the biasing force of the gas spring to lift the trunk lid.

[0008]

[Action]

 In the trunk lid pushing-up device having the above structure, when the trunk lid is unlocked from the completely closed state, even if the gas spring falls down substantially parallel to the back surface of the trunk lid, the reaction force of the gas spring causes the biasing force. A moment acts around the pivot pin at the upper end of the elbow tension lever, which causes the elbow tension lever, which was in a tilted state, to stand up and rotate like a toggle link and securely lift the trunk lid with respect to the vehicle body to obtain an appropriate height. Bring it up. With this, the unlocked state of the trunk lid can be determined at a glance, and it becomes easy to put a finger under the trunk lid, and the trunk lid can be easily flipped up and opened. Even during the flip-up opening operation, the gas spring exerts an urging force by the reaction force to assist the opening operation of the trunk lid to the upper side, and also to support the upper open state of the trunk lid.

【Example】

 An embodiment of the trunk lid lifting device of the present invention will be described below with reference to FIGS. In the figure, the same components as those shown in FIGS. 6 and 7 are designated by the same reference numerals to simplify the description.

First, as shown in FIGS. 1 and 2, one end of a gas spring 7 is pivotally attached to the upper portion of the quarter panel 1a of the vehicle body 1 via a pivot pin 8 so as to be rotatable in the up and down direction, as in the prior art. It has been burned. On the other hand, a bracket 11 is projectingly provided on the rear surface of the trunk lid 3 on the upper side, and an elbow tension lever 12 is pivotally attached to the bracket 11 at an upper end thereof via a pivot pin 13 so as to be attached in a hanging state. Has been. The other end of the gas spring 7 is rotatably connected to a substantially middle portion in the vertical direction of the elbow tension lever 12 via a pivot pin 14.

The elbow tension lever 12 is a kind of toggle link that stretches or tilts between the rear surface of the trunk lid 3 and the upper surface of the quarter panel 1a of the vehicle body 1. That is, as shown in FIG. 3, when the trunk lid 3 is closed, the lower part of the elbow tension lever 12 abuts against the upper surface of the quarter panel 1a of the vehicle body 1 and slides forward to incline to the angle θ. When the latch is unlocked, as shown in FIG. 4, the trunk lid 3 is lifted up by rotating upright to a substantially right angle by the moment acting around the pivot pin 13 by the biasing force of the gas spring 7. In order to make this operation smooth, the elbow tension lever 12 as a whole is formed into a substantially J-shaped plate when viewed from the side, and the lower end portion is in sliding contact with the upper surface of the quarter panel 1a of the vehicle body 1 and the coating film thereon A resin cover 13a having excellent wear resistance is fitted for protection. Further, the standing rotation of the elbow tension lever 12 is restricted by a stopper 15 provided on the bracket 11 within an acute angle with the back surface of the trunk lid 3.

The operation of the trunk lid pushing device constructed as described above will now be described. First, as shown in FIGS. 1 and 3, when the latch lid is unlocked from the state in which the trunk lid 3 is completely closed, even if the gas spring 7 falls down substantially parallel to the back surface of the trunk lid 3, the reaction force of the gas spring 7 A moment acts around the pivot pin 13 at the upper end of the elbow tension lever 12 due to the urging force of the elbow tension lever, and thereby the elbow tension lever 12 in the tilted state stands up and turns like a toggle link, as shown in FIG. Firmly lift the trunk lid 3 with respect to the vehicle body 1 and lift it up to a height h (about 10 cm). Further standing rotation of the elbow tension lever 12 is restricted by a stopper 15.

With this, the latch unlocked state of the trunk lid 3 can be discriminated at a glance, and the trunk lid 3 can be easily flipped up by putting the finger on the lower rear side of the trunk lid 3 and pulling it up lightly. You can open it. Also at this time, the gas spring 7 exerts an urging force by the reaction force, assists the upward opening operation of the trunk lid 3, and also supports the upward opening state of the trunk lid 3.

When the trunk lid 3 in the open state is pushed down and rotated, the gas spring 7 rotates together with this and rotates downward to return to the original substantially horizontal state. The lower part of the lever 12 contacts the upper surface of the quarter panel 1a of the vehicle body 1 and returns to the initial tilted state of the angle θ while sliding forward.

As the latch of the trunk lid 3 is unlocked, the lifting force Ft for the gas spring 7 to rotate the elbow tension lever 12 upright to lift the trunk lid 3 is as shown in FIG. Letting F be the urging force due to the reaction force of the spring 7, M be the moment about the pivot pin 13, and θ be the tilt angle of the elbow tension lever 12, then Ft = M / ACcosθ = F × BCsinθ / ACcosθ

[0016] Therefore, even if the gas spring 7 falls down substantially parallel to the rear surface of the trunk lid 3, the reaction force of the gas spring 7 causes the moment F around the pivot pin 13 at the upper end of the elbow tension lever 12 to generate the moment M of the elbow tension lever. 12 is rotated upright so that the trunk lid 3 can be reliably lifted.

[0017]

[Effect of the device]

 Since the trunk lid lifting device of the present invention is configured as described above, it is a simple improvement that an elbow tension lever is added, and the trunk lid in the fully closed state is automatically adjusted to an appropriate height by urging the gas spring when unlocking. It is possible to easily lift up, and it is easy to determine whether or not the trunk lid is unlocked, and it is easy to put a finger under the trunk lid, which makes it very easy to open the trunk lid. Be done.
