This application claims priority to Japanese Patent Application No. 2020-124677, filed on Jul. 21, 2020, the entire contents of which are incorporated herein by reference.
The art disclosed herein relates to a vehicle.
Japanese Patent Application Publication No. 2007-30706 describes a single-passenger compact vehicle. In this vehicle, a main body of a door is constituted of synthetic resin, by which weigh reduction is achieved in the vehicle.
In general vehicles, a window panel provided in a door is opened and closed by an elevating device. The elevating device for the window panel is arranged inside the door and includes a mechanism configured to move the window panel in an up-down direction in accordance with an operation of a motor or manipulation by a user. Contrary to this, in a single-passenger compact vehicle as the one described above, a window panel configured to be manually raised and lowered may be employed. A window panel configured to be manually raised and lowered refers to a window panel that is configured to be manipulated in the up-down direction directly by the user without intervention of an elevating device. For example, employing the window panel configured to be manually raised and lowered reduces the weight of the vehicle since the aforementioned elevating device is not necessary. The window panel configured to be manually raised and lowered is not limited to being employed in a window frame provided in a door, but it may be employed in a window frame provided in a vehicle body.
The window panel configured to be manually raised and lowered is movable between an upper limit position where the window panel closes an opening of the window frame and a lower limit position where the window panel opens the opening of the window frame. At the upper limit position, the window panel may be locked with respect to the window frame to avoid the window panel dropping under its own weight. On the other hand, at the lower limit position, the window panel may not necessarily be locked with respect to the window frame since the position of the window panel is maintained under its own weight. However, when the widow panel is not locked, the window panel may tend to vibrate while the vehicle is traveling.
In view of the above, the disclosure herein provides art that reduces vibration of a window panel at a lower limit position in a vehicle that employs the window panel configured to be manually raised and lowered.
A vehicle disclosed herein may comprise a vehicle body; a door provided on the vehicle body and configured to be opened and closed with respect to the vehicle body; a window frame provided in the vehicle body or the door; a window panel provided in the window frame, configured to be manually raised and lowered, and supported to be movable between an upper limit position where the window panel closes an opening of the window frame and a lower limit position where the window panel opens the opening of the window frame; a lower support comprising a groove, the groove being configured to receive a lower edge of the window panel when the window panel is located at the lower limit position; and an anti-vibration member having viscoelasticity, disposed in the groove of the lower support, and configured to hold the window panel from both sides of the window panel. The window panel configured to be manually raised and lowered refers to a window panel that is manipulated directly by a user in an up-down direction without intervention of a mechanism such as an elevating device.
In the vehicle described above, the window panel configured to be manually raised and lowered is employed in the window frame provided in the door or the vehicle body. This window panel is configured to be directly manipulated by a user in an up-down direction between the upper limit position where the window panel closes the opening of the window frame and the lower limit position where the window panel opens the opening of the window frame. When the window panel is at the lower limit position, the lower edge of the window panel is housed within the groove of the lower support. The position of the window panel is thereby stabilized. Further, the anti-vibration member that holds the window panel from both sides thereof is disposed in the groove of the lower support. Thereby, vibration of the window panel can be reduced, for example, while the vehicle is traveling.
In an embodiment of the disclosure herein, an anti-vibration member may include a first lip abutting one surface of a window panel and a second lip abutting another surface of the window panel. In this case, the first lip and the second lip may extend in parallel with each other along a longitudinal direction of a groove of a lower support. In such a configuration, the anti-vibration member contacts a lower edge of the window panel over an elongated range, and thus vibration of the window panel can be effectively reduced.
In the above embodiment, the first lip may be provided with a first guide surface which inclines downward toward the second lip and the second lip may be provided with a second guide surface which inclines downward toward the first lip. Such a configuration can guide, when the window panel is moved toward the lower limit position, the lower edge of the window panel into a space between the two lips by the guide surfaces.
In addition to or instead of the above, the first lip may cover a first upper surface of the lower support that is located on one side of the groove and the second lip may cover a second upper surface of the lower support that is located on another side of the groove. Such a configuration prohibits, when the window panel is moved toward the lower limit position, the lower edge of the window panel from contacting the upper surfaces of the lower support.
In an embodiment of the disclosure herein, at least a part of the anti-vibration member may be constituted of a rubber material. The rubber material is one of materials having suitable viscoelasticity to reduce the vibration of the window panel. The rubber material may be natural rubber or synthetic rubber. The rubber material herein includes those called elastomers.
In an embodiment of the disclosure herein, the window frame may be provided in the door. With such a configuration, when the door is opened or closed with the window panel positioned at the lower limit position, the window panel can be stably supported by the lower support and the anti-vibration member. However, the window frame is not limited to being provided in the door and may be provided in a vehicle body. In this case, the window frame is not limited to being provided in an outer surface of the vehicle body but it may be provided inside the vehicle body, and the window panel may be a partition between two seats.
In the above embodiment, a pair of guide rails which slidably supports a pair of side edges of the window panel may be provided inside the door. With such a configuration, the window panel at the lower limit position can be more stably supported when the door is opened or closed.
In an embodiment of the disclosure herein, a knob configured to be gripped by a user may be provided on the window panel. Such a configuration facilitates the user to manipulate the window panel using the knob. However, the knob is not mandatory. In another embodiment, a recess in which the user can insert a finger may be directly provided in the window panel.
In the above embodiment, the knob may be provided with a movable hook configured to be manipulated by the user. In this case, the window frame may be provided with a hook receiver configured to engage with the hook to lock the window panel when the window panel is located at the upper limit position. This configuration may lock the window panel at the upper limit position such that the window panel does not drop.

The vehicle 10 further includes a door 20. The door 20 is on the right side of the vehicle body 13 and is configured to be opened and closed with respect to the vehicle body 12. The door 20 is provided for a user to get into and get out of the vehicle 10. The door 20 is attached to the vehicle body 12 via a hinge (not shown) and is swingable in a horizontal direction. A window frame 22 is provided in the door 20. The window frame 22 is located in an upper portion of the door 20. Two bars 24 and 26 are provided within the window frame 22. The two bars 24 and 26 are parallel to each other and extend substantially in the up-down direction. The window frame 22 and the two bars 24 and 26 define three window openings 28a, 28b, and 28c. The position of the door 20 may be on the left side of the vehicle body 12. The position of the door 20 may be designed in accordance with national or regional regulations.
The three window openings 28a, 28b, and 28c include a first window opening 28a, a second window opening 28b, and a third window opening 28c. The first window opening 28a is located forward of the second window opening 28b and the third window opening 28c and is surrounded by the window frame 22 and one bar 24. A first window panel 30 is provided in the first window opening 28a. The first window panel 30 cannot be opened nor closed and is fixed to the window frame 22 and the one bar 24. The second window opening 28b is located in the middle and is surrounded by the window frame 22 and the two bars 24, 26. A second window panel 32 is provided in the second window opening 28b. The second window panel 32 can be opened and closed and is attached such that it is movable in the up-down direction between the to two bars 24 and 26.

Here, each of the window panels 30, 32, and 34 is not limited to being constituted of glass, but they may be constituted of another transparent or semitransparent material such as acrylic resin.
The second window panel 32 is configured to be manually raised and lowered. A window panel configured to be manually raised and lowered refers to a window panel that is manipulated directly by a user in the up-down direction without intervention of a mechanism such as a conventional elevating device. Hereinbelow, the second window panel 32 and configurations related thereto will be described in detail with reference to
As shown in
The knob 60 includes a movable hook 62 configured to be manipulated by the user. The window frame 22 includes a hook receiver 64 corresponding to the hook 62. The hook receiver 64 engages with the hook 62 when the window and 32 is at the upper limit position. The window panel 32 at the upper limit position is thereby locked such that it does not drop under its own weight, for example. The positions of the knob 60, the hook 62, and the hook receiver 64 are not particularly limited. For example, the knob 60 and the hook 62 may be at different positions from each other. Alternatively, the hook 62 may be provided on the window frame 22 and the hook receiver 64 may be provided on the window panel 32.
As shown in
The anti-vibration member 44 is disposed in the groove 42 of the lower support 40. The anti-vibration member 44 is constituted of a rubber material and has viscoelasticity. This rubber material may be natural rubber, synthetic rubber, or a combination thereof. The material constituting the anti-vibration member 44 is not limited to the rubber material. At least a part of the anti-vibration member 44 may be constituted of a material having viscoelasticity. In this case, the material constituting the anti-vibration member 44 may be more flexible (that is, have lower rigidity) than the material constituting the window panel 32. Further, the material constituting the anti-vibration member 44 may be more flexible than the material constituting the lower support 40. In other words, the lower support 40 may be constituted of, for example, a material having higher rigidity than the window panel 32, and thereby the window panel 32 is firmly supported. When the window panel 32 is supported by the lower support 40, the window panel 32 is prohibited from directly contacting the lower support 40 by the anti-vibration member 44 being interposed between the lower support 40 and the window panel 32. Thus, even when the lower support 40 has relatively high rigidity, damage to the window panel 32 can be avoided.
The anti-vibration member 44 includes a first lip 46 and a second lip 48. The first lip 46 is configured to abut one surface 32x (outer surface) of the window panel 32 and the second lip 48 is configured to abut another surface 32y of the window panel 32. Thus, the anti-vibration member 44 is configured to hold the window panel 32 at the lower limit position on the both surfaces 32x and 32y, Thereby, vibration of the window panel 32 can be reduced while the vehicle 10 is traveling or when the door 20 is opened or dosed, for example. The shape of the anti-vibration member 44 in the present embodiment is a mere example. The specific shape of the anti-vibration member 44 is not particularly limited. The anti-vibration member 44 according to the present embodiment has an identical cross-sectional shape along its longitudinal direction (that is, along the front-rear direction). However, in another embodiment, the cross-sectional shape of the anti-vibration member 44 may be varied continuously or intermittently along the longitudinal direction of the anti-vibration member 44.
The first lip 46 and the second lip 48 extend in parallel with each other along a longitudinal direction of the grove 42 of the lower support 40 (that is, along the front-rear direction). In such a configuration, the anti-vibration member 44 contacts the lower edge 32a of the window panel 32 over an elongated range, and thus vibration of the window panel 32 is effectively reduced. Alternatively, the first lip 46 and the second lip 48 may be provided intermittently along the longitudinal direction of the groove 42. Further, the first lip 46 and the second lip 48 are not necessarily adjacent to each other, and they may be provided alternately along the longitudinal direction of the groove 42. Although not particularly limited, the lips 46 and 48 according to the present embodiment each have a curved, thin plate-like shape, and thus they have a curved, thin plate-like shape that exhibits excellent elasticity. Here, the thin plate-like shape refers to a plate-like shape with a thickness of 3 mm or less. Further, the first lip 46 and the second lip 48 may be bilaterally symmetrical or be asymmetric.
The first lip 46 is provided with a first guide surface 46a. The first guide surface 46a is a part of upper surface of the first lip 46 and inclines downward toward the adjacent second lip 48. Similarly, the second lip 48 is provided with a second guide surface 48a. The second guide surface 48a is a part of upper surface of the second lip 48 and inclines downward toward the adjacent first lip 46. Such a configuration can guide, when the window panel 32 is moved toward the lower limit position, the lower edge 32a of the window panel 32 into a space between the two lips 46 and 48 by these guide surfaces 46a and 48a.
Additionally, as shown in
The first lip 46 covers a first upper surface 40a of the lower support 40 that is located on one side (right side) of the groove 42. The second lip 48 covers a second upper surface 40b of the lower support 40 that is located on another side (left side) of the groove 42. With such a configuration, when the window panel 32 is moved toward the lower limit position, the lower edge 32a of the window panel 32 is prohibited from contacting the upper matinees 40a and 40b of the lower support 40. Thus, even when the window panel 32 is manipulated with a great force or when the window panel 32 drops under its own weight, for example, damage to the window panel 32 can be avoided.
