Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cowl top cover mounted between a front windshield and a front hood (bonnet) of an automobile, and more particularly to a cowl having an end rubber attached to an end edge of the front windshield side. Regarding the top cover.

[0002]

2. Description of the Related Art A cowl top cover is mounted between a lower edge of a front windshield and a front hood (bonnet), and has an insertion hole for inserting a rotation shaft of a wind wiper, a slit for ventilation and a drainage guide. It has a groove. The cowl top cover is formed by drawing a gentle curve, matching one of the long edges of the cowl top cover with the shape of the lower edge of the front windshield, and is made of a soft resin at the portion contacting the front windshield. The end rubber is attached.

While the end rubber is made of a soft material, the cowl top cover is made of a hard material, but the end rubber and the cowl top cover are integrally formed due to the complicated structure of the cowl top cover. This is not possible, and conventionally, the edges of these members have been bonded and fixed with an adhesive material.

However, when members having different rigidity and long length are adhered and fixed by an adhesive, it is difficult to align the positions, and the work efficiency is lowered. Furthermore, since the end rubber made of a soft material expands and contracts greatly due to heat, the adhesion part with the cowl top cover may peel off.

Therefore, various proposals have been made regarding the mounting structure of the end rubber and the cowl top cover. For example, in Japanese Utility Model Laid-Open No. 7-17615, a mounting portion to the cowl top cover is made of a hard material, a lip portion in contact with the front windshield is made of a soft material, and the mounting portion and the lip portion are integrally formed. An end rubber formed is disclosed. The end rubber and the cowl top cover bond hard materials to each other with an adhesive, so that the bonding is strong.

Further, in the publication, a fitting concave portion is formed along the length direction of a mounting portion made of a hard material of an end rubber, and the edge of the cowl top cover is directed toward the bottom surface of the fitting concave portion. A structure for attaching by push-fitting is also disclosed. The work of attachment by this fitting is easy, and the attachment strength is larger than that of adhesive fixing with an adhesive.

[0007]

However, in the mounting structure of the cowl top cover and the end rubber by the above-mentioned fitting, the cowling in which the fitting recess of the end rubber is fitted to the same portion for the mounting. Since it is formed to be dimensionally larger than the fitting edge of the top cover, a gap is created in the fitting recess in the mounted state, and rattling occurs between the end rubber and the cowl top cover body. Furthermore, the fitting dimensions are not constant due to molding and temperature changes, which causes a problem that the end rubber separates from the cowl top cover body. Also, since the cowl top cover body and the end rubber mounting part are made of a hard material,
If the fitting recess is excessively deformed during the fitting operation, the original shape cannot be restored, and the desired fitting force may not be obtained.

Further, the hard portion and the soft portion of the end rubber are extruded at the same time by the extrusion molding method to be integrally molded. In the end rubber integrated by this molding, the hard material and the soft material are The boundary with the material may be exposed on the surface, and it becomes difficult to unify the luster and color tone of the resin surface at the boundary between the different resins, and the appearance is impaired.

The present invention has been made to solve the above problems, and its specific object is to simplify the work of attaching the cowl top cover body and the end rubber and to make a rattling in the attached state. The present invention is to provide a cowl top cover having a mounting structure capable of ensuring a strong mounting strength, and further to provide a cowl top cover having an improved appearance.

[0010]

[Means for Solving the Problems] In order to solve the above problems,
The present invention comprises a cowl top cover body made of a hard material and an end rubber composed of a lip portion made of a soft material and a cowl top cover body mounting portion made of a hard material, and the cowl top cover body and the cowl top cover body mounting. In the cowl top cover, the part includes a fitting recess and a fitting part that are fitted to each other, and a part of the cross section of the fitting recess has a dimension part slightly larger than the corresponding cross-section part of the fitting part. The main configuration is that a protruding member that elastically contacts a part of the inner wall surface of the fitting recess is provided at a predetermined interval in the corresponding small-sized portion of the fitting portion.

For example, the cowl top cover main body is provided with a fitting portion along the lengthwise edge thereof, and the end rubber has a fitting concave portion at the cowl top cover main body mounting portion. In order to attach and, the one end of the fitting portion of the cowl top cover body is inserted in the length direction from the end of the fitting recess of the end rubber, and the fitting is performed by relatively sliding.

Since the protruding member protruding from the fitting portion presses the inner wall surface of the fitting recess in the state of being mounted in the fitting recess, the mounting strength between the cowl top cover main body and the end rubber is increased and the deviation is caused. Prevent rattling.

Further, preferably, an engaging ridge portion is formed in the fitting recess and an engaging groove portion is formed in one fitting portion, and these are engaged with each other, whereby the cowl top cover main body and the end rubber are formed. The and are not easily separated, and further rattling is prevented.

Further, even if the protruding member is made of a resin material, it can be slightly elastically deformed relatively to the mating cowl top cover body mounting portion in its mounted state. It is preferable that the projecting dimension is configured to be elastically deformable in a direction in which it is positively reduced, and the tip end surface is configured as a guide surface that is easily guided to the fitting recess. By having such a guide surface, in the fitting operation of the end rubber and the cowl top cover main body, the fitting concave portion can be smoothly fitted without the projection member projecting from the fitting portion being caught in the insertion opening of the fitting concave portion. Allows to be inserted inside. At the same time, if the projecting member can be elastically deformed in the direction in which the projecting dimension is reduced, the insertion and sliding work can be further facilitated. Further, the fitting concave portion and the fitting portion made of a hard material are not subjected to an unreasonable deformation force, so that the members are prevented from being cracked or damaged due to permanent deformation, and are improved in appearance and durability.

When the surface of the projecting member which is elastically contacted with the fitting recess of the end rubber is formed into a ratchet tooth shape, the projecting member is inserted when the fitting portion of the cowl top cover body is relatively inserted into the fitting recess of the end rubber. The biting force does not act between the surface of the mating recess and the inner wall surface of the fitting recess, enabling smooth insertion, but ratchet teeth act in the opposite direction so as to bite into the inner wall surface of the fitting recess. , Once the insertion is completed, it is difficult to pull out the fitting portion of the cowl top cover body from the fitting recess of the end rubber.

Usually, the deformable projecting member is integrally formed with the cowl top cover body, but another member made of a material such as spring steel which is easily elastically deformed is integrally attached to the cowl top cover body. You can also

According to the second aspect of the present invention, the end rubber is made of a resin material having two different materials, but the exposed surface of the portion made of a hard material is covered with a soft material.
In this case, the boundary line between the two materials is not exposed, and the appearance is not impaired, and the contact surface between different materials is increased due to the coating of the exposed surface, so the bonding strength at the same bonded portion is increased. Furthermore, at the joint between the cowl top cover body mounting portion and the lip portion, if the cross-sectional area of the soft material is gradually increased from the covering portion to the lip body, the joint area will increase further, so the joint strength will increase. And the sink mark caused by the difference in contraction at the joint portion is prevented because the cross-sectional area does not change abruptly.

Further, if at least a part of the lower surface of the cowl top cover main body mounting portion is covered with the same soft material as the constituent material of the lip portion, when the cowl top cover is attached to the front windshield, the front windshield made of glass is used. Only the part of the end rubber made of a soft material comes into contact with, and the cowl top cover body attachment part made of a hard material does not come into direct contact with the front windshield to prevent chatter noise.

On the other hand, the end rubber 20 in this embodiment.
The cowl top cover body mounting portion 22 has a cross section of a substantially J-shape laid laterally, and the upper and lower end edges of the cowl top cover body mounting portion 22 each have a first engaging ridge portion 22d and a second engaging ridge portion 22d that protrude inward. Engaging ridges 22e are provided so as to project. The first engaging protrusion 22d engages with the notch 17 'formed between the engaging protrusion 17 and the long edge 11, and the second engaging protrusion 22e engages with the fitting. It engages with a wedge-shaped second engagement groove portion 12c formed between the attachment portion 132 and the cowl top cover body 34. Therefore, the wall thickness of the first engaging protrusion 22d is set to be substantially equal to the gap of the notch 17 '.

To attach the cowl top cover body 34 and the end rubber 20, the cowl top cover body 3
4 is inserted from one end of a fitting recess 23 formed in the cowl top cover body mounting portion 22 of the end rubber 20 and both members are slid relative to each other to end the cowl top cover body 10 and the end. Fit the rubber 20. At this time, since the upper surface of the fitting portion 132 has few contacting portions with the fitting concave portion 23, sliding friction does not occur and the fitting work is smoothly performed.

Further, when the end rubber 20 and the cowl top cover main body 34 are fitted, the wedge-shaped second engaging groove portion 12c of the fitting portion 132 is fitted into the second engaging projection of the fitting concave portion 23 of the end rubber 20. The long-edge 1 is formed by engaging the protruding portion 17 provided on the fitting portion 132 with the ridge portion 22e.
The first engaging protrusion 22d of the fitting recess 23 engages with the notch 17 'formed between the first and second recesses 1 and 2, as described above. That is,
The cowl top cover body 34 and the end rubber 20 are 2
Since it is engaged and attached at a location, its attachment strength is strong. Further, the wedge-shaped second engaging groove portion 12
The engagement between the c and the second engagement protrusion 22e prevents the cowl top cover main body 34 and the end rubber 20 from rattling in the vertical direction, and the notch 17b of the engagement piece 17 and the first engagement. The engagement with the mating protrusion portion 22d prevents the rattle of the cowl top cover body 34 and the end rubber 20 in the horizontal direction.

In this embodiment, the protruding height of the engagement piece 17 is determined by the upper surface of the fitting portion 132 and the upper wall portion 22 of the fitting recess 23.
Since the height of the space formed between the inner surface of a and a is set to be slightly larger, the apex of the hypotenuse 17a elastically presses the upper wall portion 22a of the fitting recess 23 to firmly attach. In particular, rattling in the vertical direction can be effectively prevented.

Further, as a modified example of this embodiment, the fitting portion 13 is provided.

The projecting dimension of the bent portion of the spring steel material 40 from the end edge 142a is the same as the end edge 142a.
It is set to be slightly larger than the depth d of the space formed between a and the inner surface of the side wall 20c of the fitting recess 23.

When the fitting portion 142 is fitted in the fitting concave portion 23, the spring steel material 40 is bent in a V shape, and the bent portion is attached so as to project from the end edge 142a. Since it increases gradually, spring steel material 40
Is smoothly inserted without being caught in the insertion opening of the fitting recess. Further, since the spring steel material 40 is elastically deformed so that it can be pushed in a direction in which the protruding dimension is reduced during the insertion work,
The insertion work can be done smoothly.

When the fitting is completed, the spring steel material 40 tries to return to the original state. However, the protruding size of the spring steel material 40 at the bent portion is fitted to the end edge 142a of the fitting portion 142. Since the depth d of the space formed between the recess 23 and the inner surface of the side wall 22c is set to be slightly larger, the bent portion of the spring steel material 40 has the bent portion of the side wall 22c.
Elastically presses the inner surface of the. Therefore, the cowl top cover main body 35 and the end rubber 20 are firmly fitted together, and rattling in the horizontal direction is completely prevented.
Further, in this embodiment, since the protruding member having a required elasticity is attached as a separate body, it is not necessary to give the material forming the fitting portion 142 a special elasticity, and the range of selection of the material is widened. It is a thing.

FIG. 19 shows a cowl top cover body 36 which is a modification of the sixth embodiment.

The lower surface covering portion 51b is also formed by partially extending to the outer surface of the.

According to this embodiment, since the outer surface of the upper wall portion 52a of the fitting recess 53 is covered by the upper surface covering portion 51a, the boundary between the fitting recess 53 and the lip portion 51, which are made of different materials, is the boundary. No lines appear on the surface and the appearance is not impaired. In addition, since the bonding area between the different materials becomes large, it is possible to prevent floating due to delamination at the bonding portion. Furthermore, a part of the lower wall portion 52b of the fitting recess 53 is covered with the lower surface covering portion 51b of the lip portion 51, and the bottom surface 54 of the front windshield contact portion 54 is covered.

[0075]

As is apparent from the above description, according to the present invention, the cowl top cover main body and the cowl top cover main body mounting portion made of a hard material are provided with the fitting concave portion and the fitting portion which are fitted to each other. A part of the cross section of the fitting recess has a dimension portion slightly larger than the corresponding cross-section portion of the fitting portion, and the corresponding small dimension portion of the fitting portion is spaced by a predetermined distance. Since the protruding member that is elastically contacted with a part of the inner wall surface of the fitting recess is projected, the cowl top cover main body and the end rubber are inserted into the fitting recess from one end of the fitting part in the length direction, It can be attached by sliding relatively and ensuring the attachment strength.

That is, according to the present invention, on the side of the side end surface of the fitting portion, the portion that comes into contact with the inner wall surface of the fitting recess is only the tip end surface of the projecting member, so contact friction during sliding This reduces the number of fittings and facilitates the fitting work. Further, since the projecting member elastically presses the inner wall surface of the fitting recess, the cowl top cover body is firmly fitted between the cowl top cover body and the end rubber, and rattling is completely prevented.

Further, the work for attaching the cowl top cover body and the end rubber is carried out by inserting the cowl top cover main body and the end rubber from one end so that the axis line of the fitting portion is aligned with the axis line of the fitting recessed portion. The fitting force is prevented from being lowered due to the deformation of the fitting recess caused by arranging the fitting part in parallel with the fitting recess and pushing the entire length of the fitting part into the fitting recess, and a high quality product is obtained. .

Further, an engaging ridge portion is formed inside the fitting concave portion, and an engaging groove portion which engages with the engaging ridge portion is formed in one fitting portion, and these are engaged with each other. As a result, the cowl top cover body and the end rubber are not easily separated, and further rattling is prevented.

When the tip surface of the projecting member has a guide surface, when the fitting section is inserted into the fitting recess, the projecting member is smoothly fitted without being caught in the insertion opening of the fitting recess. It becomes possible to insert into the mating recess. At the same time, when the projecting member is configured to be elastically deformable in the direction in which the projecting dimension is reduced, the insertion and sliding work can be further facilitated. Further, the fitting concave portion and the fitting portion made of a hard material do not exert an unreasonable deforming force, so that cracking and damage are prevented, and the appearance and durability can be improved.

When the surface of the protruding member elastically contacting the fitting recess of the end rubber is formed into a ratchet tooth shape, when the fitting portion of the cowl top cover body is relatively inserted into the fitting recess of the end rubber. The biting force does not act between the surface of the protruding member and the inner wall surface of the fitting recess, allowing smooth insertion, but ratchet-shaped teeth bite into the inner wall surface of the fitting recess in the opposite direction. The fitting portion of the cowl top cover body that has been actuated and is once inserted is difficult to pull out from the fitting recess of the end rubber.

Normally, the deformable projecting member is integrally formed with the cowl top cover body, but another member made of a material such as spring steel which is easily elastically deformed is integrally attached to the cowl top cover body. In addition, it is not necessary to give a special elasticity to the material forming the fitting portion, and the range of selection of the material is expanded.

The end rubber is composed of resin materials having two different materials, but the exposed surface of the hard material can be covered with a soft material. The boundary line does not appear and the appearance is not impaired, and since the contact surface between different materials increases due to the covering of the exposed surface, the joint strength at the same joint portion increases. Furthermore, at the joint between the cowl top cover body mounting portion and the lip portion, when gradually increasing the cross-sectional area of the soft material from the covered portion to the lip body, the joint area further increases and the joint strength increases. At the same time, since there is no sudden change in the cross-sectional area, sink marks (sync marks) caused by the difference in contraction at the joint portion are prevented.

Further, when at least a part of the lower surface of the cowl top cover main body mounting portion is covered with the same soft material as the constituent material of the lip portion, when the cowl top cover is attached to the front windshield, the glass front windshield is attached. Only the part of the end rubber made of a soft material comes into contact with the end cover, and the cowl top cover main body attachment part made of a hard material does not come into direct contact with the front windshield, so that chatter noise is prevented.

When manufacturing a mold for mass production of products,
By only finely adjusting the mold projection shape of the cowl top cover body, you can obtain the desired end rubber assembly accuracy, which reduces manufacturing costs and facilitates high-quality products. Obtainable.
