Description

The present invention relates to a vehicle door structure.

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

In the vehicle door structure, the lower sash may be arranged above the latch (for example, Patent Document 1). In such a case, water droplets such as rainwater adhering to the door glass may flow down along the lower sash and catch on the latch. Water on the latch can cause rust and malfunction of the latch.

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

Patent Document 1 states that the water droplets that fall down the sash are guided from the lower end of the sash through the water droplet passage to a position off the latch, so that the water droplets do not catch on the latch.

The sash described in Patent Document 1 covers the side portion of the latch by a water droplet passage provided in the outer sash. Therefore, the water droplet passage of the outer sash needs to overlap with the side portion of the latch when viewed from the vertical direction of the vehicle. For this reason, if the latch is located away from the outer sash, the outer sash must have a large water droplet passage to cover the sides of the latch.

Furthermore, water droplets such as rainwater may fall not only on the outside of the outer sash but also on the outside of the inner 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 off the latch, and measures are taken in the case where the water droplets falling down the inner sash are applied to the latch. Not done.

In view of such problems, it is an object of the present invention to provide a vehicle door structure capable of preventing water traveling on the outside of the lower sash from being applied to the latch.

In order to solve the above problems, a typical configuration of the 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. In the vehicle door structure, the lower sash has a main body portion that extends in the vertical direction of the vehicle and has an inner side wall, an outer wall, and a connecting wall that surrounds the rear edge of the door glass from the inside, the outside, and the rear of the vehicle, respectively. A water receiving part that overhangs the outside of the main body and is located above the latch attached to the inside of the vehicle door. It is characterized by being provided with an introduction port for introducing the water received by the receiving portion to the inside of the main body portion.

According to the present invention, it is possible to provide a vehicle door structure capable of preventing water traveling on the outside of the lower sash from being caught by the latch.

It is a figure which shows the vehicle door of the vehicle door structure in this Example. It is a figure which shows the inside of the vehicle door of FIG. FIG. 2 is an enlarged view showing a region A, which is a main part of the vehicle door structure of FIG. 2. It is a B arrow view of the door structure for a vehicle of FIG. It is a figure which shows the end surface along the DD line of the door structure for a vehicle of FIG. 3 is a diagram showing a CC cross section and an EE cross section of the vehicle door structure of FIGS. 3 and 4. It is a figure which shows the FF cross section of the vehicle door structure 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 including a vehicle door and a long lower sash that guides the raising and lowering of the door glass inside the vehicle door. In the structure, the lower sash is a main body portion having an inner side wall, an outer wall and a connecting wall extending in the vertical direction of the vehicle and surrounding the rear edge of the door glass from the inside of the vehicle, the outside of the vehicle and the rear side of the vehicle, respectively, and the main body portion. A water receiving part that projects outward and is located above the latch attached to the inside of the vehicle door, and a water receiving part that is formed in the main body and communicates between the main body and the water receiving part. It is characterized by being provided with an introduction port for introducing the received water to the inside of the main body.

According to the above configuration, the water receiving portion of the lower sash projects in a direction away from the main body portion and is further located above the latch. Therefore, for example, water such as rainwater that adheres to the door glass and flows down the outside of 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. As a result, it is possible to prevent water traveling on the outside of the lower sash from being applied to the latch or to reduce the amount of water applied to the latch without providing a separate component for covering the latch.

The vehicle door structure described above further comprises an elastic glass run that is assembled inside the lower sash body and is in contact with the trailing edge of the door glass, with the water receiver and inlet on the connecting wall of the lower sash body. A bulging portion that is formed and bulges toward the glass run and forms a gap between the connecting wall and the glass run by abutting on the glass run on the inner side wall and the outer wall of the main body of the lower sash. It is good that is formed. As a result, the glass run is supported by the bulging portions formed on the inner side wall and the outer wall of the main body portion of the lower sash, and a gap is further formed between the glass run and the connecting wall of the main body portion. Therefore, the water introduced from the water receiving portion through the introduction port 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 route.

The water receiving portion may have a bottom portion continuous with the introduction port, and the bottom portion may be inclined downward toward the introduction port. Here, the lower sash may extend in the vertical direction of the vehicle and further incline 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 an upright rib is formed at the bottom of the water receiving portion of the lower sash, and the rib is continuous to the introduction port and connects the lower side and the upper side of the introduction port. Here, the rigidity of the main body may decrease due to the formation of the introduction port in the main body. Even in such a case, according to the above configuration, the rigidity of the main body can be supplemented by connecting the lower side and the upper side of the introduction port with ribs and partitioning the introduction port with ribs.

The vehicle door structure described above further comprises a sash reinforcement that is mounted inside the vehicle door and extends vertically along the trailing edge of the window frame of the vehicle door, the sash reinforcement being the lower edge of the window frame. It is preferable to have a lower end portion which is located below the water receiving portion and bulges toward the water receiving portion. As a result, the water flowing down from the vicinity of the trailing edge of the window frame of the vehicle door along the sash reinforcement is easily introduced from the lower end portion of the sash reinforcement to the water receiving portion of the main body portion. Therefore, it is possible to reduce the amount of water traveling through the sash reinforcement on the latch.
