Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an automobile lid opening/closing device for opening and closing, for example, a trunk lid that covers a trunk room in an openable/closable manner.

(Prior Art) Conventionally, as the above-mentioned automobile lid opening/closing device, for example, there is a device described in Japanese Utility Model Application No. 61-83765.

That is, while fixing the lower bracket to the peripheral member of the trunk opening on the vehicle body side,
A trunk lid that can be opened and closed to cover the above-mentioned trunk compartment opening is provided, an upper bracket is fixed to the lower surface of the inner panel of the trunk lid, two links are provided between the lower bracket and the upper bracket, and two links are provided between the lower bracket and the upper bracket. This is an automobile lid opening/closing device in which a stay damper is stretched between the lower bracket and the free end of the lower surface of the inner panel of the trunk lid to support the above-mentioned trunk lid so that it can be opened and closed.

However, in the conventional device described above, when the lid lock mechanism is unlocked, the trunk lid cannot be lifted up to a predetermined intermediate height between the fully closed state and the fully open state, and the lock is simply released. When opening the
It is necessary to lift the trunk lid itself by inserting one's hand into the gap between the rear edge of the trunk lid and the vehicle body, making the opening operation relatively inconvenient.

Conventionally, in order to solve such problems, the present applicant has already invented a device as described in, for example, Japanese Patent Application No. 62-63177.

That is, the vehicle body and the lid are connected via a hinge and a damper, and the vehicle body side mounting portion of the damper is attached to the link rotatably attached to the vehicle body side.
This is an automobile lid opening/closing device that lifts up the lid to a predetermined intermediate height between a fully closed state and a fully open state by rotating the link when a damper reaction force is applied.

According to this device, when the lid lock mechanism is unlocked, the link rotates due to the reaction force of the damper, and the protrusion provided on this link moves the lid from the fully closed position via the hinge of the four-bar link structure. It has the advantage of being able to lift up to a large predetermined height, that is, a predetermined intermediate height between the fully closed state and the fully open state. The problem was that lift-up could not be obtained.

(Purpose of the invention) This invention improves the operability of opening and closing the lid by lifting the lid to a predetermined height greater than the fully closed position when a damper reaction force is applied, and also allows the above-mentioned lift-up operation to be performed smoothly. The purpose of the present invention is to provide an automobile lid opening/closing device that can open and close an automobile lid.

(Structure of the invention) This invention is an automobile lid opening/closing device in which the car body and the lid are connected via a hinge and a damper, and a rotating link is rotatably supported on a bracket attached to the car body. The tip of the damper is attached to the rotary link in order to transmit the reaction force of the damper as a rotational motion, and the rotary link has a push-up portion that pushes up the lid when the reaction force of the damper is applied. A projection is formed on either the vehicle body side or the link side, and a guide portion is formed on the other, and the guide portion is set as an engagement hole that engages with the projection and guides movement of the damper. In addition, the length of the engaging hole portion is set to a predetermined length that allows the lid to be lifted up to a predetermined height by rotation of the rotary link.

(Effect of the invention) According to this invention, when the lid lock mechanism is unlocked, the rotation link rotates due to the reaction force of the above-mentioned damper, and the above-mentioned lid is rotated by the push-up portion of the rotation link via the hinge. Since the lid is lifted up to a predetermined height corresponding to the length of the engagement hole and larger than the fully closed position, operability of opening and closing the lid can be improved.

Moreover, since the rotation of the above-mentioned rotary link is guided by the protrusion and the guide section (engaging hole section), there is an effect that the above-mentioned lift-up operation can be carried out smoothly.

(Example) An example of this invention will be described in detail below based on the drawings.

The drawing shows a lid opening/closing device for an automobile, and in FIG.

This trunk room 3 consists of rear fender panels 4, 4 on both sides of the rear vehicle body, and a rear end panel 5.
The opening 6 of the trunk room 3 is surrounded by
is provided with a trunk lid 7 that can be opened and closed.

As shown in FIG. 2, the above-mentioned rear end panel 5 has a key cylinder 8 and a locking lever 9.
A lid lock mechanism 10 consisting of the following is provided.

On the other hand, the trunk lid 7 described above is constructed by joining an outer panel 11 and an inner panel 12, and the inner panel 12 at the free end of the trunk lid 7
A striker 13 is attached to the lower surface of the locking lever 9 and is removably engaged with the locking lever 9 described above.

Incidentally, an upper bracket 15 is fixed to the lower surface of the base end of the inner panel 12 mentioned above via a concave member 14 shown in FIG. Fixed.

The front end rising portion 16a of the lower bracket 16 on the vehicle body side and the upper bracket 1 on the lid side
A short first link 19 is stretched between the front end 15a of the lower bracket 16 and the front end 15a of the upper bracket 15 via the pivot pins 17 and 18, and the intermediate rising part 16b of the lower bracket 16 and the front part 15b of the upper bracket 15 are A long second link 22 is stretched between them via pivot pins 20 and 21 to form a hinge 23 having a four-bar structure.

Further, a pivot link 2 is connected to the rear end rising portion 16c of the lower bracket 16 via a pivot pin 24.
5 is rotatably pivoted.

As shown in FIG. 3, this rotation link 25 is formed into a substantially U-shape, and a pin hole 26 through which the above-mentioned pivot pin 24 is inserted is bored at the rear upper end 25a of this U-shape. A push-up piece 27 for directly pushing up the upper bracket 15 by coming into contact with the lower surface of the upper bracket 15 is integrally formed on the front upper end 25b.

Further, a tip 29a on the rod 29 side serving as a vehicle body side attachment portion of the stay damper 28 is pivotally attached to one side of the above-mentioned rotation link 25, and this stay damper 28
Cylinder tube 30 as the lid side mounting part of
The side end portion 30a is pivotally attached to a predetermined portion of the lower surface of the inner panel 12 at the free end of the trunk lid 7, as shown in FIG.

Further, a protrusion 31 is provided protruding from the rear lower end 25c on the other side of the U-shaped rotation link 25,
This projection 31 is covered with a cylindrical rubber 32 for preventing noise generation.

On the other hand, in the lower bracket 16 on the vehicle body side, an elongated hole 33 as a guide portion is bored in the portion facing the free end of the above-mentioned rotation link 25, and inside this elongated hole 33, the aforementioned protrusion 31
is inserted. Then, the length of the elongated hole 33 is set to a predetermined length that allows the trunk lid 7 to be lifted up to a predetermined intermediate height between the fully closed state and the fully open state by rotation of the rotary link 25. There is.

The illustrated embodiment is configured as described above,
The action will be explained below.

Now, when the lid lock mechanism 10 shown in FIG.
are pressed in the same direction, the pivot link 25 pivots by a predetermined angle in the clockwise direction in the drawing with the pivot pin 24 as a fulcrum, and the push-up piece 27 of the pivot link 25 lifts the upper bracket 15. Since the trunk lid 7 is pushed up in the opening direction, the trunk lid 7 is automatically lifted up to a predetermined height greater than the fully closed position, as shown in FIG.

This lift-up amount is determined by the difference in length between the first and second links 19 and 22 constituting the four-bar hinge 23, the magnitude of the biasing force of the stay damper 28, and
It depends on the size of the elongated hole 33.

In this way, since the above-mentioned trunk lid 7 is automatically opened to a predetermined height, it is possible to improve the operability of opening and closing the lid.

Moreover, the rotation of the rotation link 25 described above is caused by the rotation of the protrusion 3.
1 and the elongated hole 33 serving as the guide portion, the above-mentioned lift-up operation can be carried out smoothly.

In addition, the push-up piece 27 of the above-mentioned rotation link 25
Since it directly pushes up the hot bracket 15,
For example, even if there is some wobbling in the pivot joints of the first link 19 and the second link 22, the trunk lid 7
can be smoothly opened to the above-mentioned predetermined height.

Furthermore, since the above-mentioned protrusion 31 is coated with rubber 32, the protrusion 31 is prevented from directly abutting against the edge of the elongated hole 33, thereby having the effect of preventing abnormal noise from occurring.

The above-mentioned opening operation of the trunk lid 7 above a predetermined height is performed by the operator's push-up operation, and it goes without saying that the trunk lid 7 can be arbitrarily opened to the fully open position with its own weight and the biasing force of the stay damper balanced. It is.

In terms of the correspondence between the structure of this invention and the above-mentioned embodiment, the lid of this invention corresponds to the trunk lid 7 of the embodiment, the hinge corresponds to the hinge 23 of the four-bar structure, and the damper: Although the bracket corresponds to the stay damper 28, the bracket corresponds to the lower bracket 16, and the guide portion corresponds to the elongated hole 33, the present invention is not limited to the configuration of the above-described embodiment.

For example, instead of the elongated hole 33 in the above-mentioned guide part,
It goes without saying that the lower bracket 16 may be constructed by protruding a bead forming an engagement hole.
