Abstract

(57) [Abstract] [Purpose] To provide a bonnet sealing device which can secure a sufficient fastening force between the bonnet and the sealing member and has good serviceability of the sealing member. [Structure] The pitch of the clip 6 is set to be 1 mm to 4 mm shorter than the pitch P of the large diameter portion of the locking hole 7. That is, the clip is attached to the seal member 4 in the range of P-1 mm to P-4 mm. When the seal member 4 to which the clips are attached at such a pitch is attached to the bonnet 3, since the pitch of the clips 6 of the seal member 4 is smaller than the pitch P of the large diameter portion 7b, the seal member 4 is pulled and the clip interval is increased. Insert the clip into the locking hole through the large diameter part so that it is slightly widened. After insertion, the seal member slightly contracts due to the elastic force of the seal member, so that the clip moves to the small diameter portion. As a result, in the locked state, all the clips engage with the small diameter portion of the locking hole. As a result, a sufficient fastening force can be secured.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bonnet sealing device.

[0002]

[Prior art]

 Conventionally, an elongated seal member is attached to the lower part of the front end of the bonnet in the vehicle width direction to seal the inside and outside of the engine room and as a cushioning material when opening and closing the bonnet. The seal member is attached to the bonnet by being locked to the bonnet at a predetermined interval. For this reason, locking holes are provided at a predetermined pitch on the lower surface of the bonnet, and correspondingly, fasteners are arranged at predetermined intervals on the seal member. A squid type clip or a canoe type clip has been conventionally known as the shape of the fastener of the seal member. The squid-type clip has an umbrella-shaped protrusion that is larger than the diameter of the locking hole. When attaching the seal member, this protrusion is pressed into the locking hole while elastically deforming it. The umbrella-shaped overhang part returns to its original state due to the elasticity of the inside and becomes larger than the locking hole, so it cannot be pulled out.

[0003]

[Problems to be solved by the device]

 In this type, the engagement between the bonnet and the seal member is stable, but it is difficult to peel it off when replacing the seal member, etc. It cannot be used. That is, the serviceability is poor.

Further, the canoe-shaped clip has a mountain-shaped projecting portion, and when the seal member is attached, it is elastically deformed similarly and is pushed into the locking hole to be locked. This clip makes it easy to peel off the seal member and allows the clip to be reused. That is, although it has good serviceability, it has a weak point that the fastening force with the seal member with the bonnet is small. Therefore, for example, when the seal member and the lower body structure are frozen, the seal member may come off the bonnet.

The present invention is constructed based on such a situation, and provides a bonnet sealing device which can secure a sufficient fastening force between the bonnet and the sealing member and has good serviceability of the sealing member. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 The present invention is configured as follows to achieve the above object. That is, in the bonnet sealing device according to the present invention, a plurality of locking holes for locking the sealing member are provided at a predetermined pitch on the lower surface side of the bonnet, and the locking holes include a small diameter portion and a large diameter portion. The locking holes are provided so that the small diameter portions thereof face each other with respect to the center line in the front-rear direction of the bonnet, and the sealing member has fasteners that engage with the locking holes. Is provided corresponding to each locking hole, and the feature of the fastener is that the pitch is not larger than the pitch of the small diameter portion of the locking hole.

[0007]

[Action]

 According to the present invention, the locking hole of the bonnet is formed of a daruma hole having a small diameter part and a large diameter part, and the small diameter part of the daruma hole of the sealing member faces each other with respect to the longitudinal centerline of the bonnet. The relationship between the fastener pitch and the pitch of the small diameter part of the locking hole is specified. That is, the pitch of the fastener is not larger than the pitch of the small diameter portion. As a result, when the seal member is attached to the bonnet, the seal member is slightly stretched. In this way, the fastener is inserted into the locking hole via the large-diameter portion, but after mounting, the seal member contracts due to the elastic force, so that the fastener moves to the small-diameter portion. This increases resistance to the peeling action of the seal member from the bonnet.

[0008]

Embodiments Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Referring to FIG. 1, a bonnet 3 for opening and closing the engine room 2 is provided at the front of the vehicle 1, and an elastic seal member 4 elongated in the vehicle width direction is attached to the lower surface of the tip of the bonnet 3. It has become. The seal member 4 cushions the lower vehicle body structural member 5 when the hood 3 opens and closes the engine room 2, and also seals the engine room 2 and the outside.

As shown in FIG. 2, the seal member 4 of this example is hollow, and squid-shaped clips 6 are attached inside the seal member 4 at a predetermined pitch. The squid clip 6 has a rectangular cross section as shown in FIG. 3, and has a head 6a, a shaft 6b, and an umbrella-shaped projecting portion 6c provided on the opposite side of the head 6a. Further, the inner panel 3a of the bonnet 3 is formed with a duller hole, that is, a locking hole 7 having a small diameter portion 7a and a large diameter portion 7b as accurately shown in FIG.

As shown in FIG. 3, in the attached state, the clip engages with the small diameter portion 7 a of the bursa hole 7. As shown in FIG. 4, the locking holes of the bonnet are provided such that the small diameter portions 7a face each other with respect to the longitudinal centerline L of the bonnet. The pitch of the locking holes 7 of the bonnet 3 is determined so that the center of the large diameter portion becomes the pitch P. Further, as shown in FIG. 5, the center points of the small diameter portion and the large diameter portion are separated by a distance a. Therefore, the pitch P'of the small diameter portion of the innermost locking hole is represented by P '= P-2a. Further, in this example, the pitch of the clip 6 is set to be 1 mm to 4 mm shorter than the pitch P of the large diameter portion. That is, the clip is attached to the seal member 4 in the range of the interval of P-1 mm to P-4 mm.

When the seal member 4 with the clips attached at such a pitch is attached to the bonnet 3, since the pitch of the clips 6 of the seal member 4 is smaller than the pitch P of the large diameter portion 7b, the seal member 4 is pulled. Insert the clip into the locking hole via the large diameter part so that the clip interval is slightly widened. After insertion, the elastic force of the seal member causes the seal member to contract slightly, so that the clip moves to the smaller diameter portion. As a result, in the locked state, all the clips engage with the small diameter portion of the locking hole. As a result, sufficient fastening force can be secured.

Further, when removing the seal member, the seal member may be pulled to move the clip to the large-diameter portion and rotated to rotate the projecting portion in the direction of the small-diameter portion to remove it through the large-diameter portion.

[0013]

[Effect of device]

 According to the present invention, a sufficient fastening force between the bonnet and the seal member can be ensured, and the seal member can be easily removed and the clip can be reused, so that the serviceability is also good.
