Description

The present disclosure relates to a structure that holds a closed panel portion in a vehicle.

A locking mechanism in which a latch is detachably attached to a striker is known as one of mechanisms for holding a closed state of a panel portion provided in a vehicle. According to this lock mechanism, when the striker is locked with respect to the latch, the closed panel portion is held and locked, and when the lock of the striker with the latch is released, the panel portion can be opened and closed. It becomes a state.
In order to prevent the panel portion held in the locked state by the above lock mechanism from rattling or generating abnormal noise due to the vibration of the vehicle, a structure has been proposed for pressing the closed panel portion. For example, there is disclosed a structure in which the cushion rubber fixed to the panel portion is pressed against a member on the frame side when the panel portion is closed (see Patent Document 1).

Microfilm of Japanese Utility Model Sho 60-119744 (Japanese Utility Model Sho 62-27965)

However, in the structure in which the cushion rubber for pressing down the panel portion is fixed as described above, when the rubber is worn, the panel portion in the locked state may not be pressed down sufficiently. Alternatively, when the size of the striker or latch is changed, the cushion rubber does not reach the member on the frame side and the panel part cannot be pressed down, or the cushion rubber interferes with the member on the frame side and the panel part cannot be closed. There is a risk of becoming.
Therefore, there is room for improvement in properly holding the closed panel portion.

The panel holding structure of the present disclosure was created in view of the above-mentioned problems, and an object thereof is to appropriately hold a closed panel portion.

The panel holding structure disclosed herein is a striker attached to one of a panel portion that is opened and closed and a body-side frame portion that supports the panel portion, and the other of the panel portion and the frame portion. A structural part attached to the structure, and a claw part rotatably supported with respect to the structural part, wherein the claw part is detachably attached to the striker, and the panel part. An adjuster mechanism that adjusts the position of the elastic body along a direction in which the elastic body is pressed against the structure section. ing.
Furthermore, it is preferable that the panel holding structure includes a positioning mechanism that fixes the position of the elastic body adjusted by the adjuster mechanism.

Therefore, even if the size of the latch or striker is changed or the elastic body is worn or aged, the position of the elastic body can be adjusted by the adjuster mechanism to ensure that the elastic body is securely attached to the structure. It can be pressed. Further, since the position of the elastic body adjusted by the adjuster mechanism is fixed by the positioning mechanism, the displacement of the elastic body can be suppressed, which contributes to the reliable pressing of the elastic body against the structure portion.

According to the disclosed panel holding structure, the closed panel portion can be held appropriately.

It is a perspective view which shows a part of vehicle to which the panel holding structure is applied. It is a top view which shows the principal part of a panel holding structure. It is an exploded perspective view showing the important section of a panel holding structure.

Hereinafter, modes for carrying out the panel holding structure will be described.
The panel holding structure of the present embodiment is installed in a vehicle, and the vehicle is provided with a panel portion that can be opened and closed. Vehicles equipped with a panel holding structure include automobiles such as buses and trucks. The panel holding structure holds the closed panel portion.

In the following embodiment, a front bumper (hereinafter abbreviated as “bumper”) provided in the front portion of the vehicle is exemplified as the panel portion that is opened and closed.
Regarding the directions used in the description of the embodiments, the forward direction of the vehicle is the front, the left and right are defined based on the state of facing the front, and the direction orthogonal to both the front-back direction and the left-right direction is the vertical direction.

[1. Constitution]
The configuration of the panel holding structure according to the embodiment will be described below.
First, the basic configuration of the panel holding structure will be described with reference to FIG.
The bumper 1 is provided so as to be openable and closable for operations such as attaching and detaching spare tires and adjusting lamps. The bumper 1 is swingably supported from one of the open position (shown by a chain double-dashed line in FIG. 1) and the closed position to the other.

Here, the bumper 1 that swings backward from the open position to the closed position and swings forward from the closed position to the open position is illustrated. The bumper 1 is provided with a double wall structure, a part of which is lined up in the front and rear.
The above bumper 1 is connected to a body-side frame portion 2 (a part of which is indicated by a broken line in FIG. 1), and a pivotal support portion 2S (indicated by a broken line in FIG. 1) is connected to the frame portion 2. It is swingably supported. Here, a front frame lower that forms a skeleton at the front of the vehicle is exemplified as the frame portion 2.

Further, a lock mechanism 3 for holding the closed bumper 1 is provided. Here, an example in which the lock mechanism 3 is arranged at each of the left and right sides of the bumper 1 will be described.
As shown in FIG. 2, the lock mechanism 3 is a mechanism in which the striker 5 is detachably attached to the latch 4. The latch 4 is attached to the frame portion 2. The striker 5 is attached to the bumper 1. Here, the striker 5 is fixed to the mounting portion 1M arranged rearward (inside) in the double-wall structure that is lined up in the front and rear of the bumper 1.

When the striker 5 is locked to the latch 4, the swinging of the bumper 1 to which the striker 5 is attached is restricted, and the closed position of the bumper 1 is maintained in a locked state.
On the contrary, when the latch of the striker 5 with respect to the latch 4 is released, the swing of the bumper 1 to which the striker 5 is attached is not restricted, and the bumper 1 is in an unlocked state in which it can be opened and closed.

The latch 4 is provided with a structural portion 4A fixed to the frame portion 2 and a claw portion 4C that rotates around a shaft 4B mounted on the structural portion 4A. The structure portion 4A supports the claw portion 4C via the shaft 4B. The claw portion 4C is rotatably supported by a shaft 4B from one of a locked position for locking the striker 5 and an unlocked position for releasing the locking to the other.

The structure portion 4A is arranged with a gap from the bumper 1 in the closed position in order to prevent interference with the bumper 1. The structure portion 4A is provided with a surface portion (hereinafter, referred to as “opposing surface”) 4F that faces the bumper 1 in the closed position.
A guide portion 4G for guiding the striker 5 swinging when the bumper 1 is closed is formed in the structure portion 4A. The guide portion 4G is a portion that is notched so as to taper toward the swing direction (here, rearward) of the striker 5 when the bumper 1 is closed.

The claw portion 4C is a member that locks the striker 5. In the claw portion 4C, the striker 5 is locked in front of the shaft 4B, and one end of the wire 4W (engagement releasing member) is connected in the rear of the shaft 4B. A return spring (not shown) that biases the claw portion 4C to the lock position is also provided.
The wire 4W is an operating member that rotates the claw portion 4C. A handle (not shown, engagement releasing member) for manually or automatically operating the position of the claw portion 4C is attached to the other end of the wire 4W. When the claw portion 4C is rotated from the locked state to the unlocked state via the wire 4W by the operation of the handle, the engagement of the claw portion 4C with the striker 5 is released.

The striker 5 swinging when the bumper 1 is closed is abutted against the claw portion 4C in the lock position from the front. The claw portion 4C is formed with an inclined surface 4I for rotating the claw portion 4C at the lock position toward the unlock position by hitting the striker 5.
When the claw portion 4C is rotated toward one side toward the unlock position by the striker 5 from the front side, the striker 5 is inserted into the guide portion 4G (here, rearward). After that, the striker 5 is locked by the claw portion 4C that is rotated to the other side by the return spring toward the lock position.

In this way, the striker 5 is mechanically locked to the claw portion 4C in association with the swing of the closed bumper 1.
The striker 5 is provided with a main body portion 5U which is engaged with and disengaged from the claw portion 4C, and a base portion 5B which is a base of the main body portion 5U. In the striker 5 in the posture attached to the bumper 1 in the closed position, the main body portion 5U is provided so as to project from the base portion 5B toward the latch 4.

The main body 5U is a U-shaped member, and both ends of the U-shape are fixed to the base 5B. A clearance is set between the main body portion 5U and the claw portion 4C or the structure portion 4A that locks the main body portion 5U in order to ensure engagement and disengagement of the claw portion 4C and the main body portion 5U. The main body 5U in the locked state has a U-shape with the open side facing forward in a side view.
As shown in FIG. 3, the base portion 5B is provided with two bolt holes H1 and H2 for mounting the striker 5 on the mounting portion 1M. Specifically, a bolt hole (hereinafter abbreviated as “first hole”) H1 located on the inner side in the left-right direction (upper left side in FIG. 3) and a bolt hole located on the outer side in the left-right direction (lower right side in FIG. 3) ( Hereinafter, abbreviated as “second hole”) H2 is formed in the base portion 5B.

Next, a member for fixing the striker 5 to the mounting portion 1M of the bumper 1 will be described with reference to FIGS. 2 and 3.
As a fastener for attaching the striker 5 to the attachment portion 1M of the bumper 1, the following fixing nut 10 and bolt 6 are provided.
・Fixed nut 10: Nut (screw member) fixedly mounted on the mounting portion 1M
-Bolt 6: Bolt (screw member) that is screwed to the fixing nut 10.

The fixed nut 10 is provided with the following two nuts 11 and 12.
First nut 11: Nut arranged at a position corresponding to the first hole H1 Second nut 12: Nut arranged at a position corresponding to the second hole H2 The nuts 11 and 12 described above are attached to the mounting portion 1M. On the other hand, the striker 5 is attached to the opposite side (front side here). These nuts 11 and 12 are arranged at positions overlapping the facing portion 4F (see FIG. 2) of the latch 4 in the front view when locked.

The bolt 6 is provided with the following two bolts 61 and 62.
-First bolt 61: A bolt that is inserted into the first hole H1 and is screwed into the first nut 11.-Second bolt 62: A bolt that is inserted into the second hole H2 and is screwed into the second nut 12. , 62 are arranged at positions overlapping the facing portion 4F (see FIG. 2) of the latch 4 in a front view when locked, like the nuts 11 and 12.

By the way, as shown in FIG. 2, in the locked state where the bumper 1 in the closed position is locked to the latch 4 via the striker 5, a clearance is set between the main body portion 5U and the claw portion 4C or the structural portion 4A. Therefore, vibration of the vehicle may cause rattling of the bumper 1 or generation of abnormal noise.
Therefore, in the panel holding structure of the present embodiment, the cushion rubber 6E (elastic body) is sandwiched between the latch 4 and the striker 5, and the adjuster mechanism 8 for adjusting the position of the cushion rubber 6E is also provided. Further, a positioning mechanism 9 for fixing the position of the cushion rubber 6E adjusted by the adjuster mechanism 8 is also provided.

In the adjuster mechanism 8, a cushion rubber 6E whose position is adjusted is attached to the head of the first bolt 61. The cushion rubber 6E is pressed against the facing portion 4F of the latch 4 in the locked state.
In addition to the first nut 11, the positioning mechanism 9 is provided with a movable nut (hereinafter referred to as “movable nut”) 7 that is screwed into the first bolt 61. The movable nut 7 is arranged between the head portion of the first bolt 61 screwed to the first nut 11 and the base portion 5B of the striker 5.

The first bolt 61 that is inserted into the first hole H1 and screwed into the first nut 11 is in a floating state in which the movable nut 7 can idle around the first bolt 61 between the head portion and the base portion 5B. If there is, it appears and disappears with respect to the mounting portion 1M when rotated to one side or the other. The cushion rubber 6E is also displaced along with this appearance. In this way, the position of the cushion rubber 6E is adjusted along the direction in which it is pressed against the facing portion 4F of the latch 4.

Since the position of the cushion rubber 6E is adjusted as described above, the first bolt 61 and the first nut 11 form the adjuster mechanism 8. In the adjuster mechanism 8, the first bolt 61 that controls the position of the cushion rubber 6E is a longer bolt than the second bolt 62.
The position of the cushion rubber 6E adjusted by the adjuster mechanism 8 is fixed when the movable nut 7 is screwed toward the base portion 5B. From this, the movable nut 7 and the first bolt 61 configure a positioning mechanism 9 that fixes the position of the cushion rubber 6E.

When the position of the cushion rubber 6E is fixed by the positioning mechanism 9, the base portion 5B of the striker 5 and the mounting portion 1M of the bumper 1 are sandwiched between the movable nut 7 and the first nut 11. When the second bolt 62 is screwed onto the second nut 12, the base portion 5B and the mounting portion 1M are sandwiched between the head portion of the second bolt 62 and the second nut 12.
In this way, the positioning of the cushion rubber 6E and the attachment of the striker 5 to the bumper 1 are simultaneously performed.

[2. Action and effect]
According to the panel holding structure of this embodiment, the cushion rubber 6E is pressed against the striker 5 even if the clearance is provided between the latch 4 and the striker 5 in the locked state. Therefore, even if vibration of the vehicle occurs, rattling and noise of the closed bumper 1 can be suppressed.

Even if the cushion rubber 6E is worn or deteriorated over time, the cushion rubber 6E can be reliably pressed against the latch 4 by adjusting the position of the cushion rubber 6E with the adjuster mechanism 8. Alternatively, even if the sizes of the latch 4 and the striker 5 are changed in design, the cushion rubber 6E can be pressed against the latch 4 by adjusting the position of the cushion rubber 6E with the adjuster mechanism 8.
Therefore, the closed bumper 1 can be appropriately held.

Further, since the position of the cushion rubber 6E adjusted by the adjuster mechanism 8 is fixed by the positioning mechanism 9, it is possible to suppress the positional deviation of the cushion rubber 6E, and the pressing of the cushion rubber 6E against the latch 4 is surely held. can do. Also from this, the closed bumper 1 can be appropriately held.
In this positioning mechanism 9, since the movable nut 7 that fixes the position of the cushion rubber 6E is also used for mounting the striker 5, it is possible to prevent the structure from becoming complicated.

For the conventional panel holding structure in which the predetermined bolt similar to the second bolt 62 is used in place of the first bolt 61 and the movable nut 7 is omitted, the adjuster is simply replaced with the first bolt 61. The mechanism 8 can be newly installed. Further, the positioning mechanism 9 can be newly installed only by adding the movable nut 7.
In addition, since the position of the cushion rubber 6E is adjusted by the rotation of the first bolt 61 screwed into the first nut 11, the position of the cushion rubber 6E is finely adjusted according to the pitch of the first bolt 61 (that is, finely adjusted). Can be adjusted).

[3. Modification]
The above-described embodiment is merely an example, and is not intended to exclude various modifications and application of techniques that are not explicitly shown in this embodiment. Each configuration of one embodiment can be variously modified and implemented without departing from the spirit thereof. Also, they can be selected or combined as needed.
For example, the latch may be attached to the bumper and the striker may be attached to the frame part. In this case, "latch" in the above-described embodiment may be read as "strike" and "strike" may be read as "latch".

Alternatively, the cushion rubber may be attached to a bolt different from the fastening bolt for fixing the striker. In other words, the bolt with the cushion rubber does not have to be used also as the fastener of the striker. In this case, another nut to which a bolt with a cushion rubber is screwed is fixedly attached to the bumper.
Besides, the object to be pressed by the cushion rubber may be a latch instead of the striker. In this case, cushion rubber may be attached to a bolt that is screwed into a nut fixed to the structural portion of the striker or the frame portion.
