[0006]
[Patent Document 1]
Japanese Utility Model Publication No. 7-35142 [0007]
[Problems to be solved by the invention]
However, in the sunroof structure, since the seal member is provided in addition to the weather strip of each lid, there is a problem that high assembling accuracy of the seal member is required and the number of parts is increased and the manufacturing cost is increased.
[0008]
Here, it is conceivable to increase the contact range between the weather strips to ensure water tightness and omit the sealing member. However, in this configuration, the solid weather strips are not sufficiently elastically deformed and the weather strips are not in close contact with each other, so that it is extremely difficult to ensure water tightness between the lids.
[0009]
The present invention has been made in view of the above circumstances, and the object of the present invention is that when the front lid and the rear lid are provided adjacent to each other, the contact between the weather strips of each lid is good. An object of the present invention is to provide a vehicle sunroof device capable of ensuring a good watertightness.
[0010]
[Means for Solving the Problems]
In order to achieve the object, according to the first aspect of the present invention, a substantially square front lid that opens and closes the front side of the roof opening and a substantially square rear lid that opens and closes the rear side of the roof opening are adjacent to each other. Each of the lids is provided with a weather strip that continuously covers the entire circumference, and when the lids are in the closed state, adjacent portions of the weather strips are in contact with each other. Of the weather strips of each lid, only the portion of the weather strip of one lid adjacent to the weather strip of the other lid is solid, and the portion other than the adjacent portion of the weather strip of the one lid and with weather strip of the other lid is configured to be hollow, rounded corners of the rear left and right of the front lid , The corner portions of the front end left and right weather strip in the rear lid, in correspondence with the corners of the rear left and right of the front cover, the left and right outer characterized by being formed so as to protrude forward.
[0011]
According to the first aspect of the present invention, when one of the hollow weather strips comes into contact with the other solid weather strip when the front lid and the rear lid are in the closed state, The weather strips are elastically deformed so as to follow the shape, and the weather strips adhere to each other. At this time, since the other weather strip is solid, the shape of the other weather strip is maintained, and high rigidity is imparted to the contact portion of each weather strip.
[0012]
Therefore, when the front lid and the rear lid are provided adjacent to each other, good water tightness can be ensured by the contact of the weather strips of each lid. That is, in order to ensure water tightness, it is not necessary to install metal parts etc. on the vehicle body side that cross the roof opening and abut the adjacent sides of each lid, and a large open area when the roof is opened can be secured. Of course, since there is no transverse member of the opening, the passengers can obtain a greater feeling of opening, which is extremely advantageous in practical use.
[0014]
In addition , the portions of the weather strip corresponding to the left and right sides of each lid come into contact with the vehicle body side, which is a rigid body. Here, the solid weather strip on the adjacent side of the lid changes into a hollow shape at the corners and becomes hollow at the left and right sides, so the contact portion of the weather strip with the vehicle body side is It is elastically deformed following the vehicle body side.
[0015]
Therefore, it is possible to ensure the water tightness of each lid and the vehicle body side while ensuring the water tightness of the contact portion of each lid. In addition, the weather strip corresponding to the contact portion between the lids and the contact portion with the vehicle body side can be configured with one member, reducing the number of parts and attaching the weather strip to the lid. Workability can be improved.
In addition, when the vehicle travels with the rear end of the front lid protruding upward from the roof side of the vehicle, wind noise is generated due to turbulence generated behind the rear end of the front lid, but it is located at the rear end of the front lid. Since the weather strip is rounded at its corners, turbulence that occurs during travel is suppressed.
Further, since the weather strip of the rear lid is formed so that the left and right outer sides protrude forward corresponding to the left and right corners of the rear end of the front lid, when each lid is in the closed state, The left and right sides of the strip are in close contact. Since the rear lid slides, its front end does not protrude from the roof side of the vehicle, and the air flow around the rear lid does not protrude even when the corner of the weather strip is protruded. There will be no major disruption.
Therefore, it is possible to reduce wind noise and wind slob sound when the front lid is in the open state while securing the water tightness of the left and right outer sides in the adjacent portion of each lid in the closed state of each lid.
[0016]
According to a second aspect of the present invention, in the vehicle sunroof device according to the first aspect, the front lid is configured to open the front side of the roof opening by moving the rear end side upward, and the rear lid is characterized by being configured so as to open the rear side of the roof opening by sliding backward.
[0017]
According to the second aspect of the present invention, in addition to the operation of the first aspect , when the front lid is in the open state, the rear end side of the front lid moves upward and protrudes from the roof side of the vehicle. When the vehicle travels in this state, wind noise is generated by turbulent flow generated behind the rear end of the front lid. At this time, since the weather strip located at the rearmost end of the front lid has a rounded corner, turbulence that occurs during travel is suppressed.
Further, since the weather strip of the rear lid is formed so that the left and right outer sides protrude forward corresponding to the left and right corners of the rear end of the front lid, each weather is closed when each lid is closed. The left and right sides of the strip are in close contact. Since the rear lid slides, its front end does not protrude from the roof side of the vehicle, and the air flow around the rear lid does not protrude even when the corner of the weather strip is protruded. There will be no major disruption.
[0018]
Therefore, it is possible to reduce wind noise and wind slob sound when the front lid is in the open state while securing the water tightness of the left and right outer sides in the adjacent portion of each lid in the closed state of each lid.
[0019]
In the invention of claim 3, wherein, in the sunroof device according to claim 2, in the rear lid, the when the lid each in the closed state, located below the adjacent portion of the front lid, A drain groove extending in the left-right direction is provided.
[0020]
According to the third aspect of the present invention, in addition to the operation of the second aspect , when the front lid and the rear lid are in the closed state, the drain groove portion provided in the rear lid is located below the adjacent portion of each lid. Located in. That is, when each lid is closed, the drain water flowing in from the surface of each lid toward the room is received by the drain groove and guided to the left and right outer sides of the vehicle. Here, the drain water refers to unnecessary water that flows from the outside of the vehicle into the vehicle compartment, such as rainwater.
[0021]
Therefore, it is possible to accurately prevent the inflow of the drain water in the indoor direction by the drain groove portion without providing a member for guiding the drain water to the outside of the vehicle across the roof opening.
According to a fourth aspect of the present invention, in the vehicle sunroof device according to any one of the first to third aspects, of the weather strips of the lids, the adjacent portion of the weather strip of the front lid is hollow. And the front lid and the rear lid have a solid state adjacent to the weather strip of the rear lid, and the front lid and the rear lid are closed after the rear lid is closed. It is characterized by that.
According to the fourth aspect of the invention, in addition to the actions of the first to third aspects, after the rear lid is closed, the front lid is closed. The adjacent portion of the hollow weather strip of the front lid moves and contacts the adjacent portion of the weather strip. Accordingly, since the adjacent portion of the hollow weather strip is elastically deformed corresponding to the weather strip in the fixed state, the weather strips can be brought into close contact with each other more reliably.
According to a fifth aspect of the present invention, in the vehicle sunroof device according to any one of the first to fourth aspects, the weather strip of each lid has the hollow shape when the lid is in a closed state. The adjacent portion of the weather strip is elastically deformed so as to follow the shape of the adjacent portion of the solid weather strip and is closely contacted with each other.
