Description
Technical Field
The present invention relates to a door seal for a vehicle. More specifically, the present invention relates to a door seal for a vehicle, which is provided along a periphery of a door of an automobile, a vehicle opening portion that opens to a vehicle body (vehicle body), or the like, and which is elastically deformed when the door is closed, thereby preventing rainwater or the like from entering a vehicle interior or the like.
Background
Conventionally, a door seal for a vehicle (also referred to as a "weather strip portion for a vehicle") is provided along a periphery of a door as a movable member and/or a vehicle opening portion of a vehicle body as a fixed member (for example, refer to patent document 1). In this vehicle door seal, the door is brought close to the vehicle opening and the closing operation is performed, so that the seal provided between the door and the vehicle body is elastically deformed and held.
Thus, the vehicle door seal is strongly pressed against the door or the vehicle body by the elastic restoring force (or elastic reaction force) of the vehicle door seal, and the gap between the door and the vehicle body can be prevented, so that the path of penetration of rainwater or the like can be blocked. As a result, intrusion of water, small foreign matters such as dust and dust other than water, small insects such as ants, and the like into the vehicle interior can be prevented, and intrusion of noise, wind, and the like from the vehicle exterior can be prevented. A comfortable space in a vehicle can be always ensured by a door seal for a vehicle, and a driver and a fellow passenger in driving are not uncomfortable.
To describe the basic structure of the vehicle door seal in detail, for example, as shown in fig. 7, the vehicle door seal 100 mainly includes: a seal base 101 fixed to a door, a vehicle body, or the like (not shown) by a known fixing device (for example, a jig); a hollow seal portion 102 integrally formed with the seal base 101, a part of which is crushed and deformed when the door is closed; and a plate-like or tongue-like lip 103 integrally formed with the sealing portion 102 and protruding outward from the outer surface 102a of the sealing portion 102.
The door seal for a vehicle is formed of an elastically deformable rubber material as a main material, and the main material having a melting property, which is heated to a predetermined temperature and adjusted in viscosity, can be molded into a desired shape by using a known resin molding technique such as an extrusion molding technique or a die molding technique (injection molding technique). The door seal for a vehicle is provided along the periphery of a door or the like, and thus is generally elongated in shape.
Therefore, it is often formed mainly by extrusion molding technology. Fig. 7 schematically shows a cross-sectional shape of the extrusion-molded seal. As a resin material such as an elastically deformable rubber material used as a main material, ethylene Propylene Diene Monomer (EPDM) or other thermoplastic elastomer is mainly used.
As described above, the vehicle door seal is provided along the periphery of the door, and the cross-sectional shape, hollow structure, shape, size, position, protruding direction, and the like of the seal portion are variously changed in order to exhibit suitable sealability depending on the position and location of the provided door. Therefore, when it is desired to mount the vehicle door seal on the entire periphery of the door, a connecting vehicle door seal (hereinafter, referred to as a "connecting seal") is used in which the vehicle door seals 100 having different cross-sectional shapes are connected to each other together with the vehicle door seal having the general shape shown in fig. 7.
Such connection and coupling of seals having different cross-sectional shapes are often performed near the corners of the door, and for example, in order to connect a vehicle door seal ("one seal") mounted in a substantially horizontal direction along the peripheral edge of the door upper portion and a vehicle door seal ("other seal") mounted in a substantially vertical direction along the peripheral edge of the door rear portion, the connection seal is used near the corners where the door upper portion and the door rear portion intersect. The connection between one seal (or the other seal) and the connection seal is performed by a known method such as thermal bonding in which the connection seals are bonded (or joined) by applying pressure while heating each other.
Here, in order to connect and join a pair of seals having different cross-sectional shapes, a connecting seal mainly disposed near a corner has a structure as described below. The device mainly comprises: a first connection part connected with the end part of one sealing element; a second connecting portion connected to an end portion of the other seal; and a seal connecting portion connecting the first connecting portion and the second connecting portion.
In this case, the first connecting portion has a cross-sectional shape substantially corresponding to the cross-sectional shape of one seal, and the second connecting portion has a cross-sectional shape substantially corresponding to the cross-sectional shape of the other seal. Further, the cross-sectional shape of the seal coupling portion, which connects the first coupling portion and the second coupling portion, is formed to gradually change from the cross-sectional shape of the first coupling portion to the cross-sectional shape of the second coupling portion.
Here, lips for stopping rainwater and the like are provided on one seal and the other seal, respectively. The size and protruding direction of the lip are different depending on the arrangement position of the sealing member. Therefore, a first extending lip portion connected to and extending from the lip portion on the one seal side is formed in the first connecting portion connected to the one seal, and a second extending lip portion connected to and extending from the lip portion on the other seal side is formed in the second connecting portion connected to the other seal.
As described above, the first connecting portion and the second connecting portion are connected to each other while changing the cross-sectional shape, and therefore the end portions of the first extending lip portion and the second extending lip portion are directly connected to each other. That is, the ends of the first and second extending lips are coupled to the seal coupling portion while being offset in a direction slightly inclined with respect to the longitudinal direction of each of the first and second extending lips. By adopting such a configuration, the first extending lip portion and the second extending lip portion are connected, and therefore, the sealing performance (water-stopping performance) can be maintained in the connecting seal.

Technical problem to be solved by the invention
However, in the case of the above-described connection seal, the following problems may occur. That is, in the seal joint portion of the connecting seal, since the end portions of the first extending lip portion and the second extending lip portion are directly connected to each other, there is a case where deformation of the joint portion of the end portions becomes difficult. As a result, a large force is required for deforming the connection portion of the end portions when the door is closed. That is, there is a tendency that resistance at the time of closing operation of the door becomes large.
As a result, the door needs to be closed with a stronger force than usual, and the door may not be reliably closed by the elderly or children with weak hand strength. That is, there is a possibility that the door closing property may be deteriorated as compared with the conventional one.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a door seal for a vehicle for connection for connecting two door seals for a vehicle having different cross-sectional shapes, which can maintain high sealing performance and which has good door closing performance capable of reliably closing a door even with a small force.

[2] The vehicle door seal according to item [1], wherein the vehicle door seal is disposed at a corner of the door and the vehicle body, and the corner of the door and the vehicle body is located at a position where a longitudinal direction of the first vehicle door seal intersects a longitudinal direction of the second vehicle door seal.
Effects of the invention
According to the vehicle door seal of the present invention, the effect of excellent door closing performance can be achieved by reducing the influence of resistance during the closing operation of the door while maintaining high sealing performance of two kinds of vehicle door seals having different cross-sectional shapes. In particular, the present invention can be applied to use in the vicinity of a corner of a door where the longitudinal direction of the first vehicle seal crosses the longitudinal direction of the second vehicle seal.

Detailed Description
Embodiments of a door seal for a vehicle according to the present invention will be described below with reference to the drawings. The door seal for a vehicle according to the present invention is not limited to the following embodiments, and various design changes, modifications, improvements, and the like may be applied without departing from the scope of the present invention.
As shown in fig. 1 to 6, the door seal for a vehicle (hereinafter referred to as "connecting seal 1") according to an embodiment of the present invention is provided in the vicinity of a corner 2 (see a region surrounded by a two-dot chain line in fig. 1) where a door upper UD and a door rear RD of a passenger car C intersect, and is a connecting door seal for connecting and connecting one end of a first door seal for a vehicle (hereinafter referred to as "first seal 3") provided along the door upper UD and a second door seal for a vehicle (hereinafter referred to as "second seal 4") provided along the door rear RD, respectively.
That is, the connecting seal 1 is used for connecting and connecting the first seal 3 and the second seal 4 formed so as to be respectively suitable for the door upper UD and the door rear RD and having different cross-sectional shapes, and by using the connecting seal 1, it is possible to prevent water or the like at the area where the first seal 3 and the second seal 4 intersect from entering into the vehicle interior.
As shown in fig. 1, the door upper UD corresponds to an upper portion of the door D of the passenger vehicle C, and the door rear RD corresponds to a portion that contacts the rear pillar RP of the passenger vehicle C and a rear vehicle body (not shown) that is provided to be connected to the rear pillar RP. That is, the door rear portion RD is provided along a peripheral edge extending in the substantially vertical direction, and the peripheral edge is located at a position farthest from an opening/closing axis (not shown) of the door D when the door D is opened or closed. Here, the structures of the first seal 3 and the second seal 4 are conventionally known, and thus detailed descriptions thereof are omitted here.
The specific configuration of the connection seal 1 according to the present embodiment will be described, and the connection seal 1 is mainly configured to include: a first connecting portion 5 connected to an end portion 3a of the first seal member 3; a second connecting portion 6 connected to the end portion 4a of the second seal member 4; and a seal connecting portion 7 connecting the first connecting portion 5 and the second connecting portion 6. These structures are integrally formed as in the first seal 3 and the like.
The connection seal 1 and the first seal 3 and the second seal 4 according to the present embodiment are each integrally formed by extrusion molding a resin material capable of elastically deforming against stress. As the resin material, the joint seal 1 and the like of the present embodiment use a material using ethylene propylene diene monomer rubber (hereinafter referred to as "EPDM") as a main raw material.
Here, the connecting seal 1 is provided along the peripheral edge near the corner 2 of the door D, like the first seal 3 and the second seal 4, and is configured to include a seal body 8 having a hollow structure therein (see fig. 4 to 6). Here, the seal body 8 is constituted by combining the structures of the first connecting portion 5, the second connecting portion 6, and the seal connecting portion 7. As shown in fig. 4 to 6, the connecting seal 1 is attached to the door D via a fixing device such as a clip CP (see a two-dot chain line in fig. 4).
Here, fig. 4 to 6 show a state (closed state) in which the vehicle body B is indicated by a two-dot chain line facing the door D and the door D approaches the vehicle body B. However, the connecting seal 1 is shown in a shape before elastic deformation.
As shown in fig. 2 and 3 in particular, in the connecting seal 1 of the present embodiment, the first connecting portion 5 provided on one end side of the connecting seal 1 has a cross-sectional shape substantially corresponding to the cross-sectional shape of the first seal 3, and is configured to further have a first extending lip 9, and the first extending lip 9 is connected to an end portion of the first lip 3b formed on the first seal 3, and extends from the first connecting portion 5 to a middle of the seal connecting portion 7 in a direction along which the first lip 3b is provided.
On the other hand, the second connecting portion 6 provided on the other end side of the connecting seal has a cross-sectional shape substantially corresponding to the cross-sectional shape of the second seal 4, and is configured to further have a second extending lip portion 10, the second extending lip portion 10 being connected to an end portion of the second lip portion 4b formed on the second seal 4, the second extending lip portion 10 extending from the second connecting portion 6 to a middle of the seal connecting portion 7 in a direction in which the second lip portion 4b is extending.
The seal connecting portion 7 is connected to the first connecting portion 5 and the second connecting portion 6, respectively, and the cross-sectional shapes of the first connecting portion 5 and the second connecting portion 6, which are different from each other, are gradually changed and connected. That is, the cross-sectional shape of the boundary portion between the first seal 3 and the first connecting portion 5 reaches the seal connecting portion 7 via the first connecting portion 5, and further reaches the boundary portion between the second seal 4 and the second connecting portion 6 via the second connecting portion 6 connected to the seal connecting portion 7, thereby realizing a smooth change in the cross-sectional shape.
As described above, the connecting seal 1 is a member in which the first connecting portion 5, the second connecting portion 6, and the seal connecting portion 7 are integrally formed by injection molding of a resin material or the like. On the other hand, the connecting seal 1 and the first seal 3 or the second seal 4 are formed with different structures. Therefore, the connection between the connection seal 1 and the first seal 3 and the like can be performed by a known technique such as thermal bonding. Thus, the connecting seal 1 can be reliably connected to the first seal 3 or the second seal 4.
As shown in fig. 2 and 3, the first extending lip 9 extending from the first connecting portion 5 and the second extending lip 10 extending from the second connecting portion 6 reach the seal connecting portion 7 formed between the first connecting portion 5 and the second connecting portion 6, respectively. Here, as shown in fig. 2 and 3, the first extending lip 9 and the second extending lip 10 are disposed apart from each other, and the protruding direction is offset by about 90 °. That is, the first extended lip 9 and the second extended lip 10 are each independently disposed on the surface of the seal coupling portion 7.
The first distal end portion 9a of the distal end of the first extended lip portion 9 is located closer to the second seal 4 than the second distal end portion 10a of the distal end of the second extended lip portion 10, while the second distal end portion 10a of the second extended lip portion 10 is located closer to the first seal 3. That is, the tips (first tip 9a and second tip 10 a) of the first and second extending lips 9 and 10 are positioned in a "staggered state" in the up-down direction and the left-right direction of the paper surface in fig. 2 and 3, respectively. Thus, the first extended lip 9 and the second extended lip 10 are partially overlapped with each other in the longitudinal direction (corresponding to the up-down direction of the paper surface in fig. 2 and 3) in the seal joint 7. More specifically, in the present embodiment, as shown in fig. 2 and 3, the first extending lip 9 extends from the first connecting portion 5 to the door rear portion RD side at the corner portion 2 of the door D. That is, the first front end portion 9a of the first extended setting lip 9 is located on the door rear RD side. Thus, the first extended lip 9 and the second extended lip 10 are partially overlapped in the longitudinal direction on the door rear portion RD side of the seal joint 7.
As described above, fig. 4 to 6 show respective sectional views of the connecting seal 1 of the present embodiment shown in fig. 3 along the line A-A ', the line B-B ', and the line C-C '. As can be seen from this sectional view, the first extended setting lip 9 is shown in a sectional view along line A-A 'in the region of the first connecting portion 5 of fig. 4, while the second extended setting lip 10 is shown in a sectional view along line B-B' in the region of the second connecting portion 6 of fig. 5.
In contrast, in a c—c' line sectional view in the region of the seal coupling portion 7 provided between the first connecting portion 5 and the second connecting portion 6, the first extending lip 9 and the second extending lip 10 are shown at positions separated from each other, respectively. Further, there is no structure between the first extended lip 9 and the second extended lip 10 to restrict the deformation when the connecting seal 1 is deformed. As a result, no unnecessary force (resistance) is generated during the closing operation of the door D, and good door closing performance can be maintained.
Fig. 8 shows an example of a cross-sectional view taken along line C-C' of the conventional connecting seal 104, as a comparison with fig. 6. In this case, a connecting piece 107 (see a hatched area in fig. 8) is provided to connect the first extended lip 105 and the second extended lip 106. That is, if the connecting seal 104 is to be deformed due to the presence of the connecting piece 107, the deformation of the first extended lip 105 and the seal connecting portion 108 may be significantly inhibited. As a result, resistance is generated when the door D is closed, and the possibility of deterioration of the door closing property increases.
In contrast, as shown in fig. 6, the first extended lip 9 and the second extended lip 10 in the seal coupling portion 7 of the connecting seal 1 according to the present embodiment are disposed separately from each other, and the deformation of both is not limited. As a result, no resistance against deformation occurs as in the connection piece 107 shown in fig. 8. Thus, good door closing is maintained.
The first distal end portion 9a of the first extended lip portion 9 is located closer to the second seal 4 than the second distal end portion 10a of the second extended lip portion 10, and the second distal end portion 10a is disposed closer to the first seal 3 than the first distal end portion 9 a. Thus, the first extended lip 9 and the second extended lip 10 are formed so as to partially and inevitably overlap in the longitudinal direction. Therefore, even when water or the like is immersed from the vicinity of the corner 2 to which the connecting seal 1 is attached, the immersion of the water can be prevented by either the first extended lip 9 or the second extended lip 10. Therefore, water or the like can be prevented from entering the vehicle interior from the outside of the vehicle. That is, the sealing performance can be maintained.
As described above, the connection seal 1 of the present embodiment has the following special configuration: the first extending lip 9 and the second extending lip 10 are disposed separately and independently from each other in the seal coupling portion 7, and the first tip end portion 9a of the first extending lip 9 and the second tip end portion 10a of the second extending lip 10 are located at positions offset in the up-down direction and the left-right direction. Thus, no resistance is generated during the closing operation of the door D, and good door closing performance can be ensured.
Further, the first extended lip 9 and the second extended lip 10 are disposed so as to partially overlap in the longitudinal direction, so that sufficient sealing performance can be maintained.
Industrial applicability
The connecting seal (vehicle door seal) of the present invention can be mounted on doors, vehicle body openings, and the like of various vehicles such as passenger cars, industrial, agricultural, and the like, and is expected to be usable in other various industrial fields. Particularly, the present invention is preferably used in the vicinity of a corner where the longitudinal directions of two vehicle door seals intersect.
