[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing support structure for a lid attached to various interior panels provided in a vehicle, and more particularly, by controlling the opening speed of the lid during the opening operation of the lid. The present invention relates to a lid opening / closing support structure that protects the lid and ensures a smooth operability of the lid.

[0002]

2. Description of the Related Art As shown in FIG. 11, a reclining space 3 is provided behind a seat 2 in a coupe type vehicle 1 for reclining a seat back 2a of the seat 2 by a reclining operation. A luggage floor lower 5 is provided to partition the reclining space 3 from the luggage room 4.

As shown in FIG. 12, the luggage floor lower 5 is made of a plate-shaped synthetic resin molded body having a partitioning function, and allows passengers to load and unload luggage from the luggage room 4 while seated on the seat 2. As described above, the luggage floor lower 5 is provided with the opening 5a, and the lid 6 that covers the opening 5a is provided so as to be openable and closable.

The lid 6 uses a plate body made of a synthetic resin injection molded body, and hinge shafts (not shown) provided on both sides of the lower end edge 6a of the opening 5a of the luggage floor lower 5 which is an interior panel. Bearings on both sides of the lower edge (also not shown) are configured to be opened and closed in the direction of the arrow in FIG. 12, and the inside of the luggage floor lower 5 is adjusted to adjust the opening and closing speed of the lid 6. An air damper 7 is attached to this to prevent a sudden opening / closing operation of the lid 6.

Next, a conventional opening operation of the lid 6 will be described with reference to FIGS. 13 (a) to 13 (c). First, Fig. 1
As shown in FIG. 3 (a), when the lid 6 closes the opening 5a of the luggage floor lower 5, the pulling force of the air damper 7 acts to prevent the lid 6 from being opened accidentally.

FIG. 13B shows a state in which the lid 6 is half-opened when the lid 6 is tilted toward the front side. At this time, the force of pulling the lid 6 toward the front side to open it can suppress the rapid opening of the lid 6 to some extent by the buffering action of the air damper 7.

FIG. 13 (c) shows the state in which the lid 6 is fully opened. From the half-opened state to the fully-opened state of the lid 6, the cushioning property of the air damper 7 is similarly utilized.
It is possible to secure a state in which the opening speed of the lid 6 is suppressed to some extent.

[0008]

As described above, the opening / closing support structure of the lid 6 described above is supported so as to be openable / closable so as to cover the opening 5a of the luggage floor lower 5 with the lower end serving as a hinge shaft, and the lid 6 is opened. The speed is adjusted by the air damper 7, but in the actual opening and closing operation of the lid 6, as the opening angle of the lid 6 increases, that is, when the lid 6 is close to full opening, the lid 6 is opened.
The opening speed of the lid 6 becomes very high due to the self-weight and acceleration of the lid 6, and the cushioning action of the air damper 7 causes the lid 6 to suddenly hit the back surface of the seat back 2a of the seat 2 and the opening and closing of the lid 6. Problems such as an unpleasant sound during operation and damage to the lid 6 have been pointed out.

Further, the connecting portion of the air damper 7 is connected to the lid 6
One of the causes of the above-mentioned problem is that it has to be set near the hinge portion and the cushioning force of the air damper 7 cannot be effectively transmitted to the lid 6 side.

The present invention has been made in view of the above circumstances, and in an opening / closing support structure of a lid for covering an opening of an interior panel such as a luggage floor lower, a shock absorbing action of a damper can be applied to all lid opening operations. Adjusting the opening speed, and especially by relaxing the opening speed of the lid from the point where the opening speed of the lid increases to the point where it fully opens, smooth operation of the lid and protection of the lid can be enhanced. It is intended to provide a structure.

[0011]

To achieve the above object, the present invention opens and closes a lid by bearing a lower end edge of a lid for covering an opening of an interior panel provided in a vehicle on a lower edge side of the opening. While freely supporting, by the cushioning action of the damper attached to the interior panel, in the lid opening and closing support structure that regulates the opening speed of the lid, the lower end edge of the lid, and the facing portion of the lower edge flange of the opening, It is characterized in that a lid opening speed adjusting means for restricting abrupt opening of the lid is provided from the half-opened state to the fully-opened state of the lid.

Here, the interior panel can be applied to interior floor panels such as luggage floor lowers and luggage side trims provided in the luggage room. The lid that covers the opening of the interior panel may be an injection-molded body of synthetic resin such as PP resin, or a composite resin plate, or a structure in which a surface of a fiber board is covered with a skin.

Further, in order to regulate the opening speed of the lid,
The damper attached to the interior panel has various types such as a coil spring inside the cylinder case, an air damper that uses the repulsive force when the coil spring contracts, an oil damper that uses the elasticity of oil to absorb shocks, etc. Although a damper can be applied, an air damper is preferable in consideration of cost, durability, weight and the like.

Next, the opening speed adjusting means of the lid does not operate at the beginning of the opening operation of the lid, but operates from the point where the opening speed of the lid increases due to the weight and the acceleration of the lid to the full opening position of the lid.

The opening speed adjusting means is provided at a portion facing the lower edge of the lid and the lower edge of the opening. For example, a cam protrusion is formed on the lower end edge of the lid so as to project downward, and when the lid opening angle is such that the lid opening speed increases, the cam protrusion contacts the lid protrusion until the lid is fully opened. A spring member such as a leaf spring may be arranged at the lower end edge of the opening so that the contact state continues. Further, instead of the leaf spring, a flexibly deformable locking piece integrally formed on the interior panel may be provided integrally with the interior panel.

On the other hand, a cam projection protruding upward is provided at the lower edge of the opening of the interior panel, and the lower end edge of the lid is bent and deformed so as to face the cam projection. A spring member may be provided.

According to the invention of the present application, the opening speed of the lid is adjusted to a certain extent by the damper at all opening angles of the lid, and in particular, the opening speed adjusting means of the present invention adjusts the opening speed of the lid depending on its own weight and acceleration. At the point where the opening speed of the lid increases, the cam projection and the spring member come into contact,
The spring member is flexibly deformed, and the spring repulsive force at that time can alleviate the rapid opening speed of the lid.

Therefore, when the lid is fully opened, the above-mentioned opening speed adjusting means does not suddenly hit adjacent parts or the floor surface, and no bumping noise (unpleasant noise) is generated, so that the lid can be smoothly opened. And the lid can be reliably protected for a long period of time.

FIG. 10 shows a modification in which a leaf spring is provided on the lid side.

A first embodiment of the present invention will be described with reference to FIGS. 1 to 8. The luggage floor lower 10 shown in FIGS. 1 and 3 is erected between the reclining space 3 of the seat back 2a of the seat 2 and the luggage room 4 as shown in FIG. 11 of the conventional example. The luggage floor lower 10 is made of an injection-molded body of PP resin, and the width dimension thereof is set to be slightly shorter than the width dimension of the luggage room 4, and the surface of the luggage floor lower 10 (the surface facing the sheet). ) Has windows on the left and right sides. An opening 11 is opened in the window portion on the right side, and a lid 20 that covers the opening 11 is openably and closably supported. The window on the left side is a lid that does not open and close, and has an escutcheon meaning.

The present invention is applied to the open / close support structure of the lid 20 which is openably / closably supported by the luggage floor lower 10. The relationship between the two will be described in detail below. First, the lid 20 is made of an injection-molded body of PP resin, and is made of a flat plate body having four corners rounded so as to match the vertical and horizontal dimensions of the opening 11 so as to cover the opening 11. When covering the lid with the lid 20,
A hinge shaft 21 protruding outward from both lower sides is provided,
Moreover, the lower end edge 20a is characterized in that the cam projections 22 are provided at two places on the left and right.

With respect to the luggage floor lower 10 supporting the lid 20, when the lid 11 is housed in the edge portion of the opening 11 so as to cover the opening 11, the product surface of the luggage floor lower 10 and the lid 20. A stepped flange 12 is formed along the peripheral edge of the opening 11 so as to be substantially flush with the surface.

As a structure for supporting the lid 20 so as to be openable and closable, the hinge shaft 2 protruding to both sides of the lower edge of the lid 20 is used.
By bearing 1 in bearing portions 13 provided on both sides of the lower portion of the opening 11, the lid 20 is rotatably supported with the hinge shaft 21 as the hinge center.

Further, in order to hold the lid 20 in the closed state shown in FIG. 3, a metal piece 23 is inserted in the center in the upper width direction on the back surface side of the lid 20, and when the lid 20 is covered, the metal piece 23 is The magnet 14 is inserted into the flange 12 at the corresponding position. Therefore, when the lid 20 is closed, the metal piece 23 is magnetically attracted by the magnet 14 and the held state of the lid 20 is maintained.

The lid 20 has a wire 31 of a damper 30 attached inside the luggage floor lower 10.
It is connected to the. In this embodiment, the damper 30 is
Although an air damper having a spring built into the hollow cylinder is used, a conventional damper such as an oil damper can also be used. That is, in the closed state of the lid 20, the lid 20 is biased in the closing direction by the wire 31 of the damper 30, so that the closed state of the lid 20 can be favorably maintained.

By the way, the feature of the open / close support structure of the lid 20 according to the present invention is that the damper 30 makes it difficult to control the opening speed of the lid 20 (particularly the opening speed at the time of full opening). When the opening operation is performed, new opening speed adjusting means A is provided to reduce the opening speed of the lid 20 between the point where the opening speed rapidly increases and the point where the lid 20 fully opens due to the weight and acceleration of the lid 20 during the opening operation. The feature is that

That is, as described above, the cam projections 22 are provided on the right and left sides of the lower end edge 20a of the lid 20 so as to project from below the opening 11 of the luggage floor lower 10 so as to correspond to the cam projections 22. In the edge flange 12a, a leaf spring 40 is provided at a position facing the cam projection 22.

A specific example of the mounting structure of the leaf spring 40 will be described with reference to FIG. As shown in FIG. 2 (a), the lower edge flange 12 a of the opening 11 in the luggage floor lower 10 holds both sides of the leaf spring 40 in order to attach the leaf spring 40 to the facing portion of the cam projection 22 of the lid 20. A holder portion 15 is formed, and a spring escape hole 16 is formed between the holder portions 15. And the leaf spring 40
Is made of a spring steel plate, and a flexurally deformable portion 41 that can be flexibly deformed is cut and raised in the center, and flat mounting portions 42 are provided on both sides thereof.

If the mounting portions 42 on both sides of the leaf spring 40 are inserted into the holder portion 15 provided on the lower edge side of the opening 11 of the luggage floor lower 10, the leaf spring 40 can be easily attached. Further, as shown in FIG. 2B, it is also possible to adopt a structure in which the holder portion 15 at one place holds the mounting portion 42 of the leaf spring 40.

Therefore, in the closed state of the lid 20 shown in FIGS. 4 and 5, the external force from the lid 20 is not applied to the leaf spring 40, but if the lid 20 is opened to the front side,
In the half-opened state of the lid 20 shown in FIG. 6, the opening speed of the lid 20 is relaxed to a certain extent by the buffering action of the damper 30. Between the half-opening time and the full-opening time shown in FIG. 6, the damper 30 can control the opening speed of the lid 20, which was difficult, as follows.

That is, as shown in FIGS. 6 and 7, in the state where the lid 20 is half opened, the cam projection 22 provided on the lid 20 is bent and deformed of the leaf spring 40 attached to the lower edge flange 12a of the opening 11. By pressing 41, the bending deformation portion 41 of the leaf spring 40 bends and deforms in the direction of the arrow in FIG. 7.

As described above, since the spring repulsive force generated when the leaf spring 40 is flexed and deformed acts on the cam projection 22 of the lid 20 in the closing direction of the lid 20, rapid opening of the lid 20 is suppressed, The opening speed of the lid 20 can be moderated.

Then, the cam projection 22 and the leaf spring 40
The relationship with and continues until the state in which the lid 20 is fully opened, as shown in FIG. 8, and even when the lid 20 is fully opened, the lid 20 does not suddenly collide with the seat back 2a.

Therefore, a hitting sound (unpleasant sound) with respect to the seat back 2a does not occur, a smooth opening operation of the lid 20 can be expected, and the lid 20 is not damaged. It can also be protected.

As described above, in the above-described embodiment, as the opening speed adjusting means A of the lid 20, the leaf spring 40 that cooperates with the cam projection 22 provided on the lid 20 is the lower edge flange of the peripheral flange 12 of the opening 11. 12a, and the spring repulsive force of this leaf spring 40 was used.
As shown in (a), the lower edge flange 12a is surrounded on three sides by the slits 43a, and one side of the lower edge flange 12a is connected to the lower edge flange 12a. good. Therefore, when the lid 20 is opened, as shown in FIG. 9B, the free end portion 43b of the locking piece 43 is pressed by the cam projection 22 of the lid 20 to be flexibly deformed, and the elastic repulsive force at that time is generated. Acts on the lid 20 to adjust the opening speed of the lid 20.

Also, the luggage floor lower 10 and the lid 2
The configuration of the facing portion of 0 may be reversed. That is, as shown in FIG. 10, the peripheral flange 12 of the opening 11
A cam projection 17 is provided on the lower edge flange 12a, and a leaf spring 44 that comes into contact with the cam projection 17 at the time when the opening speed of the lid 20 is increased is provided on the lid 20 side so as to correspond to the cam projection 17. You can

Further, as shown in FIG.
Also in the left half of the luggage floor lower 10 in FIG.
The open / close support structure for the lid 20 according to the present invention can also be applied. In that case, the damper 30 is installed on the left and right lids 20.
Can be shared against.

As described above, in the present invention, in addition to the damper 30, the cam projection 22, the leaf spring 40, or the locking piece 4 is provided.
Opening speed adjusting means A of the lid 20 including a spring member such as 3
Was applied to the opening and closing support structure of the lid 20 in the luggage floor lower 10, but it can be applied to the opening and closing mechanism of the lid such as the tool storage box in the luggage side trim and the opening and closing mechanism of the lid such as the glove box, and the interior panel. It can be applied to all open / close support structures for attached lids.

[0040]

As described above, according to the lid opening / closing support structure of the present invention, the cam projection is provided on one side between the hinge side edge portion of the lid and the main body side corresponding to the hinge side edge portion, A spring member is provided on the other side, and from the point where the opening speed of the lid suddenly increases to the full opening point of the lid, the pressing speed of the cam projection and the spring member reduces the opening speed of the lid. The lid can be opened and closed smoothly at all times, and the conventional problem of sudden collision with other parts due to the weight and acceleration of the lid can be solved, enabling quiet and smooth lid opening and closing, and protecting the lid. It has the effect of being able to increase.
