Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine cover device for a van or cab-over type automobile, and particularly to a seal structure.

In pan-type or cab-over type automobiles, an engine cover is installed inside the vehicle for inspection of the engine compartment. The size of this engine cover varies depending on the vehicle model, but
When servicing the engine room is important, the opening inevitably becomes larger. on the other hand,
If the opening of the engine cover is enlarged, a problem inevitably arises in that the sealing between the engine compartment and the passenger compartment deteriorates.

For this reason, in the past, as a seal around the engine cover, the weather strip was applied twice or a weather strip with a large shape was used to solve the problem of the opening size mentioned above. We are trying to balance this with the problem of sealing performance. However, these new problems have arisen, such as an increase in the cost of the weather strip and a reduction in the opening due to the enlargement of the contact surface, and it has been desired to solve these problems.

The purpose of this invention is to solve the above problems, and as a means to do so, the opening of the main body is covered with a hinged engine cover so as to be openable and closable, and the weather shield is placed between the main body and the engine cover along the opening. A lip is interposed between the main body and the engine cover so that the weather strip mounting surface of one member and the weather strip contact surface of the other member are parallel and inclined to each other. When the engine cover covers the opening in the body, a stopper is provided on either the main body or the engine cover that abuts the other and holds the weather strip mounting surface and the weather strip contact surface parallel to each other. It was established.

To explain the effect of this configuration, since the mounting surface and the contact surface of the weatherstrip are formed parallel and inclined, even if the projected area on the horizontal plane is small, the contact surface of the weatherstrip can be easily contacted. The area can be increased, and furthermore, the stopper can hold the weather strip mounting surface and the abutting surface in parallel, and the weather strip and the abutting surface can be brought into reliable contact and sealed.

Embodiments of the engine cover device of the present invention will be described below with reference to the drawings.

1 to 3 relate to a first embodiment of the present invention, and as shown in the figures, an opening 2 in a main body 1 forming an engine room is covered by an engine cover 3 that can be opened and closed. The engine cover 3 is hinged to the main body 1 by a hinge 4 attached to one side of the engine cover 3, and is connected to the main body 1 by a lock (not shown) on one side opposite to the one side where the hinge 4 is attached. The engine cover 3 is locked when it is closed.

A weather strip 5 made of an elastic material such as rubber or synthetic resin is interposed between the main body 1 and the engine cover 3 and extends around the entire circumference of the opening 2. The attachment part of the weather strip 5 on the main body 1 is an inclined surface 6 inclined with respect to the horizontal, and the attachment part of the weather strip 5 on the engine cover 3
The contact surface 7 is an inclined surface parallel to the inclined surface 6. Although the figure shows a case where the weather strip 5 is attached to the main body 1, it may also be attached to the engine cover 3 side.
By slanting the mounting surface 6 and the contact surface 7 of the weather strip 5 in this way, even if the projected area on the horizontal surface is small, the size sealing surface, that is, the large weather strip 5 and the contact surface 7 can be Contact area is ensured.

A stopper 8 is interposed between the main body 1 and the engine cover 3 to prevent the two members from coming closer than necessary and applying an excessive load to the weather strip 5. The stoppers 8 are disposed near both ends of the side 3a on which the hinge 4 is provided and the opposite side 3b. The engine cover 3 is supported on one side 3b by a stopper 8 and on the other side 3a by a hinge 4. In addition to the function of supporting the engine cover 3 described above, the stopper 8 also has a function of preventing the engine cover 3 from shifting. That is, since the engine cover 3 is supported on one side 3a by the hinge 4, depending on the structure of the hinge 4, a slight positional deviation may occur in a direction parallel to the one side 3a. An excessive load is applied to the weather strip 5 located on one side 3c extending perpendicularly to the other side 3c.
This is undesirable because a gap is created between the weather strip 5 located on the opposite side 3d and the engine cover 3, which causes engine noise to leak into the vehicle interior. In order to prevent this, the stopper 8 consists of a top 8a whose tip is pointed at a nearly right angle and a top support 8b that rotatably supports the top 8a, as shown in FIG. Fix it to body 1 with bolt 9, etc., and
The engine cover 3 is arranged so that both side surfaces 8c and 8d of the engine cover 3 are in contact with both inclined surfaces 3b and 3c or 3b and 3d of the engine cover 3, respectively. Therefore, when the engine cover 3 is closed, the engine cover 3
The bottom of the top 8 hits the top of the top 8 to regulate the height of the engine cover 3, and at the same time, both sides 8c and 8d of the top 8a meet the two inclined surfaces 3b, 3c or 3b, 3d at the corners of the engine cover 3. At this time, the engine cover 3 is automatically controlled to a normal position. The top 8a of the stopper 8 is made of relatively hard rubber or synthetic resin in order to prevent noises caused by metal-to-metal collisions when the engine cover 3 is opened and closed, due to vibrations when the car is running, etc. It is desirable to do so.

Next, FIGS. 4 to 6 relate to the second embodiment of the present invention, and show the structure of the stopper,
Other than the functions, the second embodiment is the same as the first embodiment. In the same figure,
Parts corresponding to the first embodiment are designated by the same reference numerals as in FIGS. 1 to 3, and their explanation will be omitted.
The different parts will be explained below.

In the second embodiment, a stopper 10 interposed between the main body 1 and the engine cover 3
is attached to the horizontal portion of the main body 1 at the immediate periphery of the opening 2. Head 10a of stopper 10
has a horizontal surface, and supports the horizontal bottom of the engine cover 3 by this horizontal surface. The stopper 10 may be disposed at any position as long as it can horizontally support the engine cover 3, but the illustrated example shows a case where the stopper 10 is disposed near a square of the square opening 2.

FIG. 6 shows an example of the stopper 10, in which the head 10a is made of relatively hard rubber, synthetic resin, etc., and a threaded portion with a reduced diameter is formed at the opposite end. It is attached to the engine cover 3 by inserting it into a hole in the main body 1 and screwing in a nut 11. In the illustrated example, the stopper 10 is shown attached to the main body 1, but it may also be attached to the engine cover 3 side.

Since the engine cover device of the present invention is constructed as described above and has the functions and actions described above,
With the engine cover device of the present invention, the contact area between the weather strip and the engine cover or main body can be substantially increased, and the stopper can hold the weather strip mounting surface and the contact surface parallel to each other. Since the weather strip and its contact surface can be brought into secure contact and sealed, it is possible to extremely effectively improve the sealing performance for preventing engine sound transmission between the engine room and the passenger compartment. .

In addition, since the weather strip is applied at an inclined position, the contact between the weather strip and the engine cover or main body can be improved compared to conventional ones even if the weather strip has a complicated shape.

Furthermore, between the main body and the engine cover,
Because the stopper is interposed, even if a large load is placed on the engine cover, such as when a passenger is placed on the engine cover, the stopper receives the load, preventing excessive load from being applied to the weather strip and preventing deformation or misalignment. Therefore, the long-term reliability and durability of the sealing function of the engine cover device can be improved. In this case, if the stopper is provided with the function of controlling the position of the engine cover as in the first embodiment, the sealing performance and durability can be further improved.
