Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a sealing structure for a back door opening of a vehicle equipped with a resin body, and more specifically, to a structure configured to improve the sealing performance of the back door opening.

[Conventional technology]

Some off-road vehicles are constructed so that the cargo area behind the roll bar is covered with a resin body made by bonding resin panels, so that the cargo space can be used as a passenger compartment. There is a car with a resin body. The resin body mounted on a car with such a resin body usually has a
A back window opening is provided for the back window to ensure rearward visibility for the driver. The back door is composed of a side-opening back door main body of the loading platform and a back window glass attached to the main body, and the back door fits into and closes the back door opening, which is composed of the above-mentioned back window opening on the resin body side and the back door opening of the loading platform. By opening and closing the door, you can freely enter and exit the cabin, which is made of resin. In addition, the back window opening of the resin body is equipped with an atspa weather strip that seals the back window opening by contacting the inner surface of the outer edge of the back window glass when the back door is closed. Lower weather strips are respectively provided which abut against the inner surface of the back door body and seal the back door opening when the back door is closed. The upper weather strip and the lower weather strip constitute a sealing structure at the back door opening.

[Problem that the invention attempts to solve]

Incidentally, the back window glass is usually attached to the back door body in an inclined forward direction in order to enhance the exterior design of the rear part of the vehicle by giving the back window part an inclination. Therefore,
In the back door of a car with a resin body, the lower end of the back window glass is generally located at a position further back in the longitudinal direction of the vehicle than the inside surface of the back door main body. It extends upward from a position displaced rearward from the inner surface of the back door body. In other words, the inner surface of the back window glass does not extend continuously from the inner surface of the back door main body in substantially the same plane.
The space between the two is stepped in the longitudinal direction of the vehicle body. For this reason, cars with resin bodies have traditionally had the problem of extremely poor sealing performance at the back door opening. That is, as described above, when the back door is closed, the back door opening is sealed by the upper weather strip that comes into contact with the inner surface of the back window glass and the lower weather strip that comes into contact with the inner surface of the back door main body. It is configured as follows.
However, it is difficult for the Atsupau weather strip to come into contact with the part of the back window glass located behind the inside of the back door body (lower end).
Furthermore, even if they do come into contact, the degree of compression is small compared to other parts, so there is the inconvenience of rainwater entering from the part of the back door opening that corresponds to the step between the back window glass and the back door body. It was hot. Of course, the back window opening to which the Atsupau weather strip is attached is formed in an oblique shape to match the inclination angle of the back window glass. but,
Because it is impossible to form the back window opening so that it extends all the way to its lower end along the back window glass when the back door is closed, due to its structure and relationship with the back door main body, The problem of not being able to obtain uniform sealing performance has become difficult to avoid. This invention was devised under the above circumstances, and is a vehicle with a resin body that has a back door that consists of a side-opening back door body on the loading platform and a back window glass attached to it. An object of the present invention is to provide a sealing structure configured to reliably seal the entire back door opening and improve the sealing performance of the back door opening.

[Means to solve the problem]

In order to solve the above problem, the present invention takes the following technical measures. That is, a back door opening consisting of a back window opening of a resin body attached to the vehicle body so as to cover the cargo bed behind the roll bar and a door opening of the cargo bed, and a back door that is pivoted in a side-opening manner to the door opening of the cargo bed. A back door consisting of a main body and a back window glass which is attached to the back door main body with a weather strip member interposed therebetween and which extends upward while having a step with respect to the inner surface of the back door main body is fitted into the back door and closed. In a vehicle equipped with a resin body, a hot weather strip is provided on the left and right edges of the back window opening of the resin body to contact the inner surface of the back window glass of the back door in the closed state. A lower weather strip is provided at the edge to abut against the inner surface of the back door body in the closed state, while a lower weather strip extends upward from the upper end of the inner surface of the back door body to fill the step between the back window glass and the back window glass. a top seal part that extends substantially flush with the inner surface of the glass and has a top seal surface that comes into contact with the top weather strip when the back door is closed;
A door opening weather strip having a lower seal portion having a lower seal surface that comes into contact with the lower weather strip when the back door is closed is attached to the entire width of the back window glass between the back door main body and the back window glass. The weather strip is characterized in that it is integrally formed on the left and right parts of the weather strip member interposed therebetween.

[Action and effect]

The top seal part, which is integrally formed with the weather strip member interposed between the back window glass and the back door main body, extends upwardly from the upper end of the inner surface of the door main body to the lower end of the back window glass. , and a top reference surface is formed that extends substantially flush with the inner surface of the back window glass. This top seal surface comes into contact with the top weather strip of the back window opening on the resin body side when the back door is closed. Therefore, when the back door is closed, the above-mentioned atsupah seal portion comes into contact with a portion of the atsupau weather strip corresponding to the step portion, and the entire atsupau weather strip can exhibit a sealing function. This solves the conventional problem of rainwater entering the vehicle interior from a portion of the back door opening corresponding to the stepped portion. Note that the Atsupa seal surface is approximately flush with the inner surface of the back window glass, and when the back door is closed, the Atsupa weather strip comes into continuous contact from the Atsupa seal surface to the inside surface of the back window glass, so that the back window opening Good sealing properties can also be obtained at the portion corresponding to the continuous portion from the upper seal surface to the inner surface of the back window glass. Further, in the present invention, the door opening weather strip is provided with a lower seal portion having a lower seal surface that extends downward continuously from the upper seal surface and comes into contact with the lower weather strip when the back door is closed. As a result, around the lower end of the upper weather strip and the upper end of the lower weather strip, where the sealing performance of the back door opening tends to deteriorate, the upper seal part and the lower seal part
Since a uniformly continuous sealing structure is formed, the sealing performance at the back door opening is greatly improved. In addition, the door opening weather strip utilizes the weather strip member that is always provided between the back window glass and the back door body, and is integrally formed therewith.
In constructing the seal structure of the present invention, the number of parts does not increase, so problems such as complicating the structure of the back door do not occur. Further, since the weather strip member is normally fixed to the back window glass, the door opening weather strip is also provided on the back window glass side. Therefore,
When the resin body is removed from the vehicle body, the back window glass is removed from the back door body, and a car with a resin body is used in a fully open state, the door opening weather strip remains on the back door body, making it look unsightly. There is no such thing. In other words, the seal structure of the present invention is
It has the advantage that the user can freely configure it whenever necessary, and there is no need to perform any special work to configure it, just attach the back window glass to the back door body. All you have to do is do the following:

[Explanation of Examples]

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. As shown in FIG. 5, a resin body 4 mounted on a vehicle equipped with a resin body is attached to the vehicle body so as to cover the loading platform 2 behind the roll bar 1.

The weather strip member 13 is attached to the back door main body 3 via the back door main body 3, and a weather strip member 13 for sealing a gap between the weather strip member and the back door main body 3 is attached to the lower end thereof. As shown in FIG. 3a, the back window opening of the resin body 4 is provided with a back window glass 11 that comes into contact with the inner surface of the outer edge of the back window glass 11 that fits into the back window opening 8 when the back door 10 is closed. The Atsupau weather strip 14 that seals the cargo area 2
A lower weather strip 1 is provided in the back door opening 2a of the vehicle, which comes into contact with the inner surface of the back door main body 3 that fits into the back door opening 2b of the loading platform 2 when the back door 10 is closed, thereby sealing the back door opening 2b.
5 are provided respectively. Further, in this example, sealing members 19 as shown in FIGS. 3a and 3b are provided on both sides of the backdoor opening, respectively. This sealing member 19 includes a first lip portion 19b having elasticity that integrally extends upward along the backwind opening 8 from a base portion 19a fixed on the top rail of the loading platform 2, and a first lip portion 19b that integrally extends from the base portion 19a. formed,
A second lip part 19c has elasticity and extends integrally and continuously from the lower end of the rear end of the first lip part 19b inward in the vehicle width direction, and a second lip part 19c has elasticity and extends inward in the vehicle width direction from the inner end of the base part 19a along the back door opening 2b of the loading platform 2. The third lip portion 19d is integrally formed downward and has an elastic third lip portion 19d whose rear end upper end is integrally continuous with the inner end in the vehicle width direction of the second lip portion 19c. The first lip portion 19
b covers the inner side of the top weather strip 14, and the rear end, which is curved toward the outside of the back door opening, wraps around the rear side of the top weather strip 14. It's covered with this. The inner side or rear part of the upper end of the lower weather strip 14 is covered by the third lip part 19d, and the second lip part 19c covers the lower rear end of the upper weather strip 14. and the rear upper end of the lower weather strip 15 in the vehicle width direction. Furthermore, in this example, in order to make it possible to configure the seal member 19 at low cost by utilizing existing members, the gap between the top rail of the loading platform 2 and the inward flange 6a of the resin body 4 bolted thereto is The rear end portion of the sheet member 20 interposed as a spacer is used as the base portion 19a. In this example, as shown in FIG. 1 and FIG.
A door opening weather strip 16 is integrally formed on the inner surface of the side end portion of the weather strip member 13 and has a lower seal portion 18 that is integrally formed at the lower end of the upper seal portion 17 and extends downward along the inner surface of the back door main body 3. It is formed and provided. The top seal portion 17 extends upward from the upper end of the inner surface of the back door main body 3 so as to fill the step between the inner surface of the back door main body and the back window glass 11, and is substantially flush with the inner surface of the outer edge of the back window glass 11. It has an upper seal surface 17a that comes into contact with the lower end of the upper weather strip 14 and the first lip portion 19b of the seal member 19 when the back door 10 is closed. Further, the lower seal portion 18 extends downward continuously from the upper seal surface 17a by a predetermined length in the vehicle width direction, and when the back door 10 is closed, the upper end portion of the lower weather strip 15, the upper end portion of the seal member 19, It has a lower seal surface 18a that comes into contact with the second lip portion 19c and the third lip portion 19d. Although the door opening weather strip 16 is shown only on one side of the back door 10 in the figure, it is similarly provided on the other side. In the seal structure of this example configured as described above, the door opening weather strip 16 is installed at the stepped portion of the back door 10 between the portion of the back window glass 11 located rearward from the inner surface of the back door main body and the inner surface of the back door main body. An atsupashi seal portion 17 is provided. Then, when the back door 10 is closed, the top seal surface 17a of the top seal portion 17 contacts the top weather strip 14.
The first lip portion 19b contacts a portion (lower end portion) corresponding to the stepped portion of the lip portion 19b.
It is also configured to come into contact with. Therefore, when the back door 10 is closed, the entire Atsupau weather strip 14 can perform its sealing function, and a portion of the Atsupau weather strip 14 cannot function as a sealing member as in the past. This inconvenience will be resolved. In addition, due to the need to ensure the back window opening 8 as large as possible, and due to the structure of the back door main body 3 and the back door opening 2a of the loading platform 2 into which it fits, hot weather stains at the back door opening inevitably occur. A second lip portion 19c of the seal member 19 is disposed at a discontinuous portion of the weather strip in the vehicle width direction between the lower end of the back door and the upper end of the lower weather strip. The lower seal surface 18a of the portion 18 abuts. Therefore, since the discontinuous portion of the back door opening is reliably sealed by the second lip portion 19c and the lower seal portion 18 that abuts it, the seal structure of this example allows the vehicle to be sealed from the discontinuous portion. Inconveniences such as rainwater entering the room are also eliminated. In addition, in addition to the sealing structure constituted by the upper weather strip 14 and the lower weather strip 15, the door opening weather strip 1 is also installed around the discontinuous portion where the sealing performance tends to deteriorate.
Since the seal member 6 and the seal member 19 cooperate to seal the back door opening, the sealing structure of this example can significantly improve the sealing performance of the back door opening. Note that the scope of the present invention is not limited to the embodiments described above. For example, whether the door opening weather strip is provided on one side or both sides of the back door is an arbitrary design decision that depends on the back door opening and the structure of the back door. Furthermore, the shapes of the upper seal portion and the lower seal portion can be modified in various ways other than those of the above-described embodiments.
