The protrusions (3) are formed near both ends of the lower edge (1c) of the lift glass (1), and extend downward where water droplets (W) flowing down from the lift glass (1) should drop.

Description

Droplet-Induced Structures for Elevating Glass

technical field

The present invention relates to a water drop guiding structure of a lift glass which can make the water drop immersed in the lift glass along the window part drop to a desired position.

Background technique

Some automobiles have doors with built-in drive mechanisms for automatically raising and lowering the windows. These driving mechanisms are equipped with electric components such as motors, so measures are taken to prevent them from being exposed to water such as rainwater. As one example, in the drainage structure of an automobile door described in Japanese Patent Document 1, the lower end portion of the window glass is formed in an arc shape with a high central portion, and a water guide groove is provided along the arc. Furthermore, both end portions of the gutter are connected to drain rails provided in the door. Therefore, the water that penetrates along the window glass is directed from the water channel to the drain rail.

Japanese Patent Document 1: Japanese Utility Model Registration No. 2603761

However, as described in Japanese Patent Document 1, when all the lower sides of the window glass (lifting glass) form a higher arc shape in the central part, there must be enough inclination to drain water along the guide rail, so the edges of the two ends of the lifting glass The size of the direction of movement will necessarily become larger. Therefore, in order to pull the lift glass into the interior of the door, a greater depth is required. In other words, if the depth is the same, the amount of pulling the lift glass into the interior of the door will be smaller than that of the lower straight lift glass. Moreover, the larger the width of the window, the more pronounced this tendency is.

And because the lower edge is all arc-shaped and the two ends are drooping, so when the lift glass is lowered, frictional force acts in the direction of receiving water from the guide rail along the lip-shaped portion of the guide rail in contact with the lift glass. As a result, a larger force is required to move the lift glass, which increases the load on the driving mechanism. In addition, it also becomes a cause of abrasion of the lip portion of the guide rail.

Therefore, it is an object of the present invention to provide a water drop guide structure for a lift glass that can appropriately induce water that enters the interior of a door along the lift glass without changing the pulling amount of the lift glass.

Contents of the invention

The water drop induction structure of the liftable glass according to the present invention comprises a water guide groove, a band-shaped fillet and a convex part. The water guide groove is installed along the both side edge parts of the lift glass installed on the vehicle window and extends up and down. Its bottom end of the belt-shaped molding is installed on the lower frame outside the compartment of the vehicle window, and its top end is in frictional contact with the lifting glass. Protrusions are formed at both ends close to the lower edge of the lift glass, and extend downward where water droplets flowing down the lift glass are to drop.

Moreover, a glass support frame is installed at a position closer to the center than the convex part, which is connected with a drive structure that moves the lifting glass in the up and down direction; on the lower edge between the glass support frame and the convex part, an upward The concave part of the square depression.

According to the water drop induction structure of the lifting glass of the present invention, the water droplets flowing in from the gap between the water guide groove and the strip molding can be actively dropped from the convex parts formed near the two ends of the lifting glass, thereby reducing water splashing on the device. On the mechanical device under the lifting glass.

Detailed ways

Next, taking the lift glass 1 of the front door 10 of an automobile as an example, the water drop induction structure of the lift glass according to an embodiment of the present invention will be described in detail with reference to accompanying drawings 1 to 4 . As shown in FIG. 1 , the front door 10 has a window 20 formed in the upper half and a door panel 30 installed in the lower half. The gutter 2 shown in FIG. 2 is attached to both side portions 21 a and an upper portion 21 b of the inner periphery of a window frame 21 corresponding to the frame of the vehicle window 20 . The water guide channel 2 installed along both side edge portions 1 a of the lift glass 1 extends to the inside of the front door 10 covered by the door panel 30 .

As shown in FIGS. 2 and 3 , a belt-shaped molding 23 is attached to the lower frame 22 on the vehicle compartment outer side of the window 20 . The top end 23a of the belt-shaped molding 23 is in frictional contact with the lift glass 1 . Therefore, in the water that rains on the lift glass 1 due to rain or car washing, the water droplet w within the range that the band-shaped molding 23 touches, as shown in FIG. 3 , flows from the lift glass 1 to the outside the compartment. Moreover, in terms of installation, a gap G is formed between the two ends 23b of the belt-shaped molding 23 and the gutter 2 .

In the state where the window 20 of the lift glass 1 is closed, both side edge portions 1 a and the upper edge 1 b are fitted into the water guide groove 2 . As shown in FIG. 1 and FIG. 4 , convex portions 3 extending downward are formed on portions near both ends of the lower edge 1c of the lift glass 1 . Moreover, the glass holder 4 is attached to the lower edge 1c of the liftable glass 1. As shown in FIG. Moreover, the lower edge 1c of the lift glass 1 between the convex part 3 and the glass holder 4 forms the recessed part 5 dented upward. Between the side edge portions 1a of the lift glass 1 and the installed water channel 2, a driving mechanism 40 capable of moving the lift glass up and down is disposed. The drive mechanism 40 is connected to the glass support frame 4 .

For the front door 10 according to the above-mentioned structure, when the drop glass 1 is drenched with water droplets such as rainwater, as mentioned above, within the range where the belt-shaped molding 23 is in contact with the lift glass 1, the water droplet w can be absorbed by the belt-shaped molding 23 wipe away. As shown in Figure 2, a part of the water drop w that is immersed into the inside of the front door 10 from the gap G formed between the band-shaped molding 23 and the water guide groove 2, as shown in Figure 4, along the water guide groove 2 and the lifting glass 1 The U-shaped ring C flows formed.

The water drop w that has flowed to the lower edge 1c of the lift glass 1 flows down toward the convex portion 3 of the lift glass 1 as shown in FIG. In this case, since the concave portion 5 is formed between the convex portion 3 and the glass holder 4 , the water drop w does not flow to the glass holder 4 side. The water drop w is actively dropped to a desired position through the convex portion 3 without flowing to the inside of the convex portion 3 , thereby reducing the water drop w from dripping onto the mechanical device arranged under the lift glass 1 .

Moreover, the lift glass 1 is formed gently from both side edges 1a to the lower edge 1c by the convex portion 3, and the tip 2b of the lip portion 2a of the gutter 2 is in contact with the lift glass 1 toward the inside of the gutter 2. Therefore, when the lift glass 1 is lowered, a frictional force acts in a direction in which the lip portion 2a of the water guide groove 2 is pushed into the water guide groove 2, thereby suppressing an increase in frictional resistance. Therefore, variations in the load applied to the drive mechanism 40 can be suppressed.

Furthermore, in this embodiment, the lift glass of the front door is taken as an example, and the water drop induction structure of the lift glass is described. However, it is also applicable to a vehicle window having a liftable glass of the same structure as a liftable glass including a rear door.
