Description

  The present invention relates to a vehicle door structure.

  The vehicle door structure includes a vehicle door and a lower sash. The lower sash is a long member, for example, and guides the raising and lowering of the door glass inside the vehicle door, and accommodates the door glass when the door glass is lowered. A latch that keeps the vehicle door closed is attached to the inside of the vehicle door.

  In a vehicle door structure, a lower sash may be disposed above a latch (for example, Patent Document 1). In such a case, water droplets such as rainwater adhering to the door glass may flow down the lower sash and hit the latch. If water is applied to the latch, it may cause rust and malfunction of the latch.

  Patent Document 1 describes a sash structure for an automobile door in which the lower end portion of the sash is located at the upper portion of the latch. The sash has an outer sash and an inner sash, and a water droplet passage is formed at the lower end of the outer sash. The water droplet passage covers the side of the latch outside the vehicle, and guides the water droplet falling along the sash to a position off the latch (the vehicle outside the latch).

  According to Patent Document 1, the water droplets that fall through the sash are guided from the lower end of the sash through the water droplet passage to a position that is out of the latch, and therefore do not reach the latch.

Japanese Utility Model Publication No. 63-114715

  The sash described in Patent Document 1 covers the side of the latch with a water droplet passage provided in the outer sash. Therefore, the water drop passage of the outer sash needs to overlap the side portion of the latch when viewed from the vehicle vertical direction. For this reason, when the latch is disposed at a position away from the outer sash, the outer sash must be formed with a large water droplet passage to cover the side of the latch.

  Furthermore, water droplets such as rainwater may fall not only on the outer sash but also on the outer sash. However, the technique described in Patent Document 1 merely guides the water droplets falling along the outside of the outer sash to a position outside the latch, and measures are taken when the water droplets falling along the inner sash hit the latch. It is not done.

  In view of such a problem, an object of the present invention is to provide a vehicle door structure that can prevent water traveling outside the lower sash from being applied to the latch.

  In order to solve the above problems, a typical configuration of a vehicle door structure according to the present invention includes a vehicle door and a long lower sash that guides the raising and lowering of the door glass inside the vehicle door. A vehicle door structure, wherein the lower sash extends in the vertical direction of the vehicle and includes a main body portion having an inner wall, an outer wall, and a connecting wall that surround the rear edge of the door glass from the vehicle inner side, the vehicle outer side, and the vehicle rear side, respectively. A water receiving portion that protrudes to the outside of the main body portion, the water receiving portion located above a latch attached to the inside of the vehicle door, and the main body portion and the water receiving portion that are formed in the main body portion communicate with each other. And an introduction port for introducing the water received by the receiving part into the inside of the main body part.

  ADVANTAGE OF THE INVENTION According to this invention, the vehicle door structure which can prevent that the water which conveys the outer side of a lower sash is applied to a latch can be provided.

It is a figure which shows the vehicle door of the vehicle door structure in a present Example. It is a figure which shows the inside of the vehicle door of FIG. It is a figure which expands and shows the A area | region which is the principal part of the vehicle door structure of FIG. FIG. 4 is a B arrow view of the vehicle door structure of FIG. 3. It is a figure which shows the end surface along the DD line of the vehicle door structure of FIG. It is a figure which shows CC cross section and EE cross section of the vehicle door structure of FIG. 3, FIG. It is a figure which shows the FF cross section of the door structure for vehicles of FIG. 4, and the cross section of a comparative example.

  A typical configuration of a vehicle door structure according to an embodiment of the present invention is a vehicle door provided with a vehicle door and a long lower sash that guides the raising and lowering of the door glass inside the vehicle door. The lower sash extends in the vehicle vertical direction and includes a main body portion having an inner wall, an outer wall, and a connecting wall that surround the rear edge of the door glass from the vehicle inner side, the vehicle outer side, and the vehicle rear side, respectively. A water receiving portion that protrudes outwardly, the water receiving portion located above a latch attached to the inside of the vehicle door, and the water receiving portion that is formed in the main body portion and communicates with the main body portion and the water receiving portion. And an introduction port for introducing the received water into the inside of the main body.

  According to the said structure, the water receiving part of a lower sash has protruded in the direction away from a main-body part, and is further located above a latch. For this reason, for example, rainwater or the like that adheres to the door glass and flows down the lower sash is first received by the water receiving portion, and then introduced into the inside of the main body portion through the introduction port and flows down. Accordingly, it is possible to prevent the water traveling outside the lower sash from being applied to the latch without providing a separate part for covering the latch, or to reduce the amount of water on the latch.

  The vehicle door structure described above further includes an elastic glass run that is assembled to the inner side of the lower sash main body and is in contact with the rear edge of the door glass, and the water receiving portion and the inlet are provided on the connecting wall of the lower sash main body. A bulge portion formed on the inner and outer walls of the lower sash body portion that bulges toward the glass run and forms a gap between the connecting wall and the glass run by contacting the glass run. Is good to be formed. As a result, the glass run is supported by the bulges formed on the inner and outer walls of the lower sash body, and a gap is formed between the glass run and the connecting wall of the body. Therefore, the water introduced from the water receiving portion through the inlet to the inside of the main body portion can flow down through the gap between the glass run and the connecting wall as a drainage path.

  Said water receiving part has a bottom part continuing to an introduction port, and it is good for a bottom part to incline below toward an introduction port. Here, the lower sash may extend in the vertical direction of the vehicle and may be inclined toward the rear side of the vehicle. Even in such a case, since the bottom of the water receiving portion is inclined downward toward the introduction port, the received water can be reliably introduced into the introduction port.

  It is preferable that a standing rib is formed at the bottom of the water receiving portion of the lower sash, the rib is continuous to the introduction port, and connects the lower side and the upper side of the introduction port. Here, when the introduction port is formed in the main body, the rigidity of the main body may be reduced. Even in such a case, according to the above configuration, the rigidity of the main body can be compensated by connecting the lower side and the upper side of the inlet through ribs and partitioning the inlet through ribs.

  The vehicle door structure described above further includes a sash reinforcement that is attached to the interior of the vehicle door and extends in the vehicle vertical direction along the rear edge of the window frame of the vehicle door, and the sash reinforcement is a lower edge of the window frame. It is good to have the lower end part which is located below rather than bulges toward the water receiving part. Thereby, the water that flows down from the vicinity of the rear edge of the window frame of the vehicle door through the sash reinforcement is easily introduced from the lower end portion of the sash reinforcement to the water receiving portion of the main body. For this reason, it can reduce that the water which conveys a sash reinforcement is applied to a latch.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the examples are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated.

  FIG. 1 is a diagram illustrating a vehicle door 102 of a vehicle door structure 100 according to the present embodiment. In the figure, a state in which the vehicle door 102 is viewed from the outside of the vehicle is shown. FIG. 2 is a view showing the inside of the vehicle door 102 of FIG. Hereinafter, the vehicle door structure 100 will be described based on the vehicle door 102 disposed on the right side surface of the vehicle. However, the vehicle door structure including the vehicle door disposed on the left side surface of the vehicle has the same function and the like. have.

  As shown in FIG. 1, the vehicle door 102 includes a door outer panel 106 that constitutes a window frame 104. As shown in FIG. 2, a sash reinforcement 108, a lower sash 110, and a latch 112 are disposed inside the vehicle door 102. FIG. 2 shows the interior of the vehicle door 102 without the door outer panel 106.

  The sash reinforcement 108 is attached to the door inner panel 114 and extends in the vehicle vertical direction along the rear edge 116 of the window frame 104. As shown in FIG. 2, the lower end portion 118 of the sash reinforcement 108 is positioned below the lower edge 120 of the window frame 104.

  The lower sash 110 is a long member made of resin, for example, and guides the raising and lowering of the door glass 122 (see FIG. 7A) inside the vehicle door 102. The lower sash 110 extends in the vertical direction of the vehicle as shown in FIG. 2 and is gently inclined toward the rear side of the vehicle.

  Further, the lower sash 110 is located below the lower edge 120 of the window frame 104, and as shown in FIG. 2, a part of the lower sash 110 overlaps the lower end portion 118 of the sash reinforcement 108 in a side view, and further the lower end portion 118. It also overlaps with the latch 112 below. The latch 112 is attached to the door inner panel 114, and keeps the vehicle door 102 closed by engaging with a striker provided on the vehicle body side (not shown).

  As described above, in the vehicle door structure 100, a part of the lower sash 110 is disposed above the latch 112. For this reason, when water droplets such as rainwater adhering to the door glass 122 enter the inside of the vehicle door 102, it may flow down the outside of the lower sash 110 and water may be applied to the latch 112. If water is applied to the latch 112, the latch 112 may rust or malfunction.

  Accordingly, the vehicle door structure 100 employs a configuration that prevents water flowing down outside the lower sash 110 from being applied to the latch 112 or reducing the amount of water on the latch 112. The water flowing downward while avoiding the latch 112 is discharged to the outside of the vehicle door 102 from the discharge port 124 provided in the door inner panel 114.

  FIG. 3 is an enlarged view showing a region A which is a main part of the vehicle door structure 100 of FIG. FIG. 4 is a B arrow view of the vehicle door structure 100 of FIG. FIG. 5 is a view showing an end surface along the line D-D of the vehicle door structure 100 of FIG. 4.

  As shown in FIG. 3, the lower sash 110 includes a main body portion 126 and a water receiving portion 128. As shown in FIG. 4, the main body 126 extends in the vehicle vertical direction, and surrounds the rear edge 130 (see FIG. 7A) of the door glass 122 from the vehicle inner side, the vehicle outer side, and the vehicle rear side, respectively. The outer wall 134 and the connecting wall 136. The water receiver 128 is formed on the connecting wall 136 of the main body 126 and protrudes to the outside of the main body 126 (here, the rear side of the vehicle) as shown in FIG. Further, the water receiver 128 is located above the latch 112 shown in FIG.

  The lower sash 110 further includes an introduction port 138. As shown in FIG. 5, the introduction port 138 is formed in the connecting wall 136 of the main body 126, and communicates the water receiving portion 128 projecting outside the main body 126 and the inside of the main body 126. For this reason, when the water receiving part 128 receives the water indicated by the broken line 140 in the drawing that travels outside the lower sash 110, the introduction port 138 introduces the water received by the water receiving part 128 to the inside of the main body part 126.

  As shown in FIG. 5, the water receiving portion 128 has a side portion 142 that extends in the vehicle vertical direction and a bottom portion 144 that continues to the side portion 142. The bottom portion 144 is continuous with the introduction port 138 and is inclined downward toward the introduction port 138. For this reason, even if the lower sash 110 is disposed so as to incline toward the rear side of the vehicle as shown in FIG. 2, the water 140 received by the water receiving portion 128 is reliably introduced from the bottom portion 144 to the introduction port 138. The

  Further, as shown in FIG. 5, the lower end portion 118 of the sash reinforcement 108 bulges toward the water receiving portion 128 and approaches the water receiving portion 128. Therefore, the water that flows down from the vicinity of the rear edge 116 (see FIG. 2) of the window frame 104 of the vehicle door 102 through the sash reinforcement 108 is easily introduced into the water receiving portion 128 from the lower end portion 118 of the sash reinforcement 108. Become. That is, the water transmitted through the sash reinforcement 108 is also received by the water receiving portion 128 as indicated by a broken line 140 in the drawing, and further introduced into the main body portion 126 through the introduction port 138 and flows down.

  Further, a water droplet passage 146 is provided in the main body 126 of the lower sash 110 as shown in FIG. The water droplet passage 146 protrudes from the inner wall 132 of the main body 126 toward the vehicle interior and is located above the latch 112. As shown in FIG. 3, the water droplet passage 146 has an open front end portion 148, and drains the received water from the front end portion 148, thereby reducing the amount of water on the latch 112.

  6 is a cross-sectional view taken along the line CC and the line E-E of the vehicle door structure shown in FIGS. 3 and 4. As shown in the EE cross section of FIG. 6B, a standing rib 150 is formed on the bottom 144 of the water receiver 128. The rib 150 continues from the side portion 142 of the water receiving portion 128 to the introduction port 138 formed in the connecting wall 136 indicated by a broken line in the drawing of the main body portion 126.

  Furthermore, the rib 150 divides the inlet 138 by connecting the lower side 152 and the upper side 154 of the inlet 138 as shown in the CC cross section of FIG. For this reason, in the lower sash 110, even if the rigidity of the main body part 126 is lowered due to the formation of the introduction port 138 in the main body part 126, the rigidity of the main body part 126 is determined by partitioning the introduction port 138 by the rib 150. Can be supplemented.

  FIG. 7 is a view showing the FF cross section of the vehicle door structure 100 of FIG. 4 and a cross section of a comparative example. The vehicle door structure 100 further includes a glass run 156 as shown in the FF cross section of FIG. The glass run 156 is a member having elasticity, is attached to the inside of the main body 126 of the lower sash 110, and is in contact with the rear edge 130 of the door glass 122.

  On the inner wall 132 and the outer wall 134 of the main body 126, bulged portions 158a and 158b bulged toward the glass run 156 are formed. The bulging portions 158a and 158b abut against the glass run 156 to support the glass run 156, and further form gaps 160a and 160b surrounded by a chain line in the figure between the connecting wall 136 and the glass run 156, respectively.

  The gaps 160a and 160b serve as a drainage path when water introduced from the water receiver 128 through the inlet 138 to the inside of the main body 126 flows down. That is, the water introduced into the inside of the main body 126 through the inlet 138 flows down as shown by a chain line 140 in FIG. 5 through the gaps 160a and 160b as drainage paths.

  On the other hand, in the vehicle door structure 200 of the comparative example shown in FIG. 7B, the bulged portions 158 a and 158 b of the vehicle door structure 100 are formed on the inner wall 206 and the outer wall 208 of the main body 204 of the lower sash 202. It has not been. For this reason, in the vehicle door structure 200, as shown in FIG. 7B, a gap as a drainage path is not formed between the connecting wall 210 of the main body 204 and the glass run 212. It becomes difficult to drain the water introduced inside.

  On the other hand, in the vehicle door structure 100 according to the present embodiment, the water that flows down the outer side of the lower sash 110 by the water receiving part 128 that is located above the latch 112 and protrudes to the outer side of the main body part 126 of the lower sash 110. Can receive. Further, the water received by the water receiving portion 128 is introduced into the inside of the main body portion 126 through the introduction port 138, and can further flow down using the gaps 160a and 160b shown in FIG. Therefore, according to the vehicle door structure 100, it is possible to prevent the water traveling outside the lower sash 110 from being applied to the latch 112 without providing another part for covering the latch 112, or to reduce the amount of water on the latch 112.

  In the above embodiment, the water receiver 128 is formed on the connecting wall 136 of the main body 126 and protrudes from the connecting wall 136 to the rear side of the vehicle, but is not limited thereto. In other words, the water receiving portion 128 may be formed on the inner wall 132 or the outer wall 134 of the main body portion 126 so as to protrude from the inner wall 132 or the outer wall 134 to the outside of the main body portion 126. In the case where the water receiving portion 128 is formed on the inner wall 132 of the main body portion 126, the water receiving portion 128 may be formed instead of the water droplet passage 146. In this manner, by forming the water receiving portion 128 so as to project outside the main body portion 126, it is possible to receive the water flowing down along the outer side of the lower sash 110.

  Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
