Description

[Technical field]

[0001] The present invention relates to a vehicle door structure. [Background technology]

[0002] A typical vehicle door structure is configured to raise and lower the door glass of a vehicle door in the vertical direction. A single-rail type window regulator is known as a mechanism for raising and lowering this door glass. The single-rail type window regulator has a guide rail that extends in the vertical direction and a carrier plate.

[0003] The carrier plate holds the lower edge of the door glass and is slidably attached to the guide rail. The carrier plate moves up and down on the guide rail via a specified wire by the power of a motor unit located at the lower end of the guide rail. In this way, the single-rail window regulator can raise and lower the door glass in the vertical direction.

[0004] In the vehicle door structure of Patent Document 1, in a sedan-type vehicle in which the front pillars are tilted so as to recede, the front door sash and the roof sash form an obtuse angle, and the window glass, which corresponds to the shape of the door sash, is raised and lowered by a single-rail window regulator. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6242120 Summary of the Invention [Problem to be solved by the invention]

[0006] In the vehicle door structure of Patent Document 1, the window glass has an obtuse angle portion that corresponds to the obtuse angle formed by the front sash and the roof sash, and furthermore, a glass run is in contact with the front edge of the window glass. The glass run is disposed continuously from the upper end to the lower end of the front sash and guides the raising and lowering of the window glass.

[0007] However, when a door glass having an obtuse angle is raised or lowered by a single-rail window regulator, the obtuse angle of the door glass may come into contact with and get stuck on the glass run, causing a malfunction of the glass lift. If this occurs, the door glass may be pressed strongly against the glass run when the door glass is raised or lowered, causing the glass run to tear, or the door glass may momentarily decrease in lift speed, causing the door glass anti-pinch device to malfunction and cause the door glass to rotate erroneously.

[0008] One possible measure to prevent glass lifting failures is to apply a lubricant such as silicone to the glass run, but this would significantly increase costs.In addition, even if a double-rail or X-arm window regulator were to be used instead of the single-rail type, the components would be larger than those of a single-rail window regulator, resulting in increased weight and reduced freedom of layout within the vehicle door.

[0009] In view of the above problems, the present invention has an object to provide a vehicle door structure that can suppress the jamming behavior of the door glass when the door glass is raised or lowered by a single-rail type window regulator. [Means for solving the problem]

[0010] In order to solve the above problems, a representative configuration of a vehicle door structure according to the present invention is a vehicle door structure including a door glass of a vehicle door and a single-rail type window regulator that raises and lowers the door glass in a vertical direction, the vehicle door structure further including a front glass run that contacts a front edge of the door glass, a rear glass run that contacts a rear edge of the door glass, and a roof glass run that connects upper ends of the front glass run and the rear glass run to form an obtuse angle with the front glass run, the door glass having an obtuse angle portion that corresponds to the obtuse angle formed by the front glass run and the roof glass run, the window regulator including a guide rail extending in the vertical direction and a carrier plate that holds the lower edge of the door glass via a pair of holders at positions spaced apart in the vehicle front-rear direction and is slidably attached to the guide rail, the carrier plate including a main body that is pulled by a predetermined wire and slides in the vertical direction on the guide rail, and a slide rail that extends in the vehicle front-rear direction, connects the pair of holders, is slidably attached to the main body, and slides in the vehicle front-rear direction relative to the main body together with the pair of holders. Effect of the Invention

[0011] According to the present invention, it is possible to provide a vehicle door structure that can suppress the jamming behavior of the door glass when the door glass is raised or lowered by a single-rail type window regulator. [Brief description of the drawings]

[0012] [Figure 1] 1 is a diagram showing a vehicle door structure according to an embodiment of the present invention; [Diagram 2] 2 is a diagram showing a main part of the vehicle door structure of FIG. 1. [Diagram 3] 3 is a diagram showing a main part of the window regulator shown in FIG. 2. [Figure 4] 3 is a diagram showing the behavior of a door glass in the vehicle door structure of FIG. 2 when it is raised or lowered. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] A representative configuration of a vehicle door structure according to one embodiment of the present invention is a vehicle door structure including a door glass of a vehicle door and a single-rail type window regulator that raises and lowers the door glass in a vertical direction, the vehicle door structure further including a front glass run that contacts a front edge of the door glass, a rear glass run that contacts a rear edge of the door glass, and a roof glass run that connects upper ends of the front glass run and the rear glass run and forms an obtuse angle with the front glass run, the door glass has an obtuse angle portion that corresponds to the obtuse angle formed by the front glass run and the roof glass run, the window regulator includes a guide rail extending in the vertical direction, and a carrier plate that holds the lower edge of the door glass via a pair of holders at positions spaced apart in the vehicle front-rear direction and is slidably attached to the guide rail, the carrier plate includes a main body that is pulled by a predetermined wire and slides in the vertical direction on the guide rail, and a slide rail that extends in the vehicle front-rear direction, connects the pair of holders, is slidably attached to the main body, and slides in the vehicle front-rear direction relative to the main body together with the pair of holders.

[0014] The carrier plate of the above configuration has a main body that slides up and down on the guide rail, and also has a slide rail that slides in the vehicle front-rear direction relative to the main body together with a pair of holders. Therefore, when the obtuse angle portion contacts the front glass run when the door glass is raised or lowered, and the door glass is pushed by the front glass run, the slide rail of the carrier plate slides toward the rear of the vehicle relative to the main body together with the holder that holds the door glass. As the slide rail slides toward the rear of the vehicle together with the holder, the door glass rotates around the center of gravity of the door glass or the vicinity of the center of gravity. As a result, not only the obtuse angle portion of the door glass contacts the front glass run, but also the corner of the rear lower end contacts the rear glass run. This corner of the rear lower end is a corner where the rear edge and the lower edge of the door glass intersect, and is located diagonally opposite the obtuse angle portion.

[0015] In other words, in the above configuration, when the obtuse angle portion comes into contact with the front glass run and the door glass rotates during raising and lowering of the door glass, the door glass comes into contact with the glass run at two points: the obtuse angle portion and the corner portion diagonally opposite the obtuse angle portion. Therefore, even if the obtuse angle portion of the door glass comes into contact with the front glass run, a moment that offsets the jamming is generated by the normal force and frictional force generated by the contact between the rear lower end corner portion and the rear glass run, and the jamming behavior of the door glass can be suppressed.

[0016] This prevents the door glass from being pressed hard against the front glass run when the door glass is raised or lowered, causing the front glass run to tear, or prevents the door glass anti-pinch device from malfunctioning and erroneously reversing due to a momentary decrease in the raising and lowering speed of the door glass.

[0017] The window regulator further includes a pulley section attached to the upper end of the guide rail and around which a wire is wound, and a motor unit located at the lower end of the guide rail, which raises and lowers a carrier plate on the guide rail via the wire by the rotational force of a drum rotated by a regulator motor, and the slide rail of the carrier plate includes a side wall extending in the vehicle longitudinal direction, an upper wall bent from the upper edge of the side wall toward the vehicle exterior, the upper wall having an upper protrusion protruding upward in the vehicle longitudinal direction, and a lower wall bent from the lower ... the lower wall having an upper protrusion protruding upward in the vehicle longitudinal direction. and a lower wall having a lower protrusion formed thereon that protrudes downward across the entire length of the carrier plate, the carrier plate further having a first fixing portion provided on the main body for fixing one end of the wire wound around the pulley portion, a second fixing portion provided on the main body for fixing the other end of the wire wound around the drum of the motor unit and extending along the guide rail, a recess formed by recessing the main body toward the inside of the vehicle, and upper and lower grooves provided in the recess and respectively holding the upper and lower protrusions of the slide rail so that they can slide in the fore-and-aft direction of the vehicle, and the first and second fixing portions are positioned to overlap with the recess in a side view.

[0018] In this way, the main body of the carrier plate is provided with a first fixing part and a second fixing part for fixing one end and the other end of the wire, respectively, so that the main body can slide up and down on the guide rail by being pulled by the wire.

[0019] The upper protrusions formed on the upper wall and the lower protrusions formed on the lower wall of the slide rail of the carrier plate are held in the upper and lower grooves provided in the recess of the main body so as to be slidable in the vehicle longitudinal direction. This allows the slide rail to slide reliably in the vehicle longitudinal direction relative to the main body together with the pair of holders, and further prevents it from falling off. The upper and lower protrusions of the slide rail can prevent, for example, rainwater dripping from the door glass from entering the recess of the main body. This allows the slide rail to slide more reliably in the vehicle longitudinal direction relative to the main body.

[0020] In addition, the first and second fixing parts of the main body are positioned so that they overlap with the recessed part in a side view. In this way, the first and second fixing parts, to which force is applied via the wire when the door glass is raised and lowered, are positioned so that they overlap with the recessed part in a side view, so that the main body does not rattle when the door glass is raised and lowered, and the posture of the main body is stable. This allows the main body to slide stably up and down on the guide rail while maintaining a constant gap with the guide rail when the door glass is raised and lowered.

[0021] The positions of the first and second fixing parts and the fitting position of the carrier plate and the guide rail are set closer to the shorter vertical side of the door glass than the center of gravity of the door glass, which makes it possible to suppress vibrations when the door glass is raised and lowered. EXAMPLES

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0023] Fig. 1 is a diagram showing a vehicle door structure 100 according to an embodiment of the present invention. The vehicle door structure 100 in the figure is applied to a front door on the right side of a vehicle, and shows a state seen from the inside of the vehicle. Fig. 2 is a diagram showing a main part of the vehicle door structure 100 in Fig. 1.

[0024] In the following drawings, the front and rear directions of the vehicle are indicated by arrows FRONT and BACK, the left and right directions of the vehicle width are indicated by arrows LEFT and RIGHT, and the up and down directions of the vehicle are indicated by arrows UP and DOWN. In the following description, the vehicle door structure 100 on the right side of the vehicle in FIG. 1 is illustrated, but the present invention is not limited to this, and the present embodiment may be applied to a front door on the left side of the vehicle, or a rear door on the right side or left side of the vehicle.

[0025] The vehicle door structure 100 includes a door glass 104 of a vehicle door 102. The vehicle door 102 has a door outer panel 106 that serves as an exterior, and a door inner panel 108 that is connected to the door outer panel 106 from the inside of the vehicle. The door glass 104 can be stored between these panels. Note that FIG. 2 shows the vehicle door structure 100 with the door inner panel 108 omitted. It has become like this.

[0026] The door glass 104 is a so-called power window that is electrically raised and lowered. The vehicle door structure 100 includes a single-rail window regulator 110 as a lifting mechanism for raising and lowering the door glass 104 in the vertical direction.

[0027] The door glass 104 is surrounded by a door sash 112, which is a window frame shown in Fig. 1. The door sash 112 is provided with a front glass run 114, a rear glass run 116, and a roof glass run 118 shown in Fig. 2, and the door glass 104 moves up and down along the front glass run 114 and the rear glass run 116. These glass runs are elastic sealing members made of resin or rubber, and seal the gap between the door sash 112 and the door glass 104.

[0028] The front glass run 114 is in contact with a leading edge 120 of the door glass 104. The rear glass run 116 is in contact with a trailing edge 122 of the door glass 104. The roof glass run 118 connects an upper end 124 of the front glass run 114 and an upper end 126 of the rear glass run 116, and as shown in Figure 2, its front end 128 is inclined so as to form an obtuse angle with the upper end 124 of the front glass run 114. The leading edge 120 and the trailing edge 122 of the door glass 104 are vertical sides of the door glass 104, and the leading edge 120 is shorter than the trailing edge 122.

[0029] For this reason, the door glass 104 has an obtuse angle portion 130 that corresponds to the obtuse angle formed by the front glass run 114 and the roof glass run 118. Here, when the door glass 104 having the obtuse angle portion 130 is raised or lowered, the obtuse angle portion 130 of the door glass 104 may come into contact with and get stuck on the front glass run 114, which may cause a failure in raising or lowering the glass.

[0030] Therefore, the vehicle door structure 100 employs a configuration that can suppress the jamming behavior of the door glass 104 when the door glass 104 is raised or lowered by the single-rail type window regulator 110.

[0031] Fig. 3 is a diagram showing a main part of the window regulator 110 of Fig. 2. Fig. 3(a) is an enlarged view of a part of the window regulator 110 of Fig. 2. Fig. 3(b) is a cross-sectional view taken along line AA of Fig. 3(a).

[0032] The window regulator 110 has a guide rail 132, a carrier plate 134, a pulley portion 136, and a motor unit 138 shown in Fig. 2. The guide rail 132 is installed on the door inner panel 108, and extends in the vertical direction as shown in Fig. 2. The carrier plate 134 holds the lower edge 140 of the door glass 104 via a pair of holders 154, 156 (see Fig. 3(a)), and is further slidably attached to the guide rail 132. The pair of holders 154, 156 hold the lower edge 140 of the door glass 104 at positions spaced apart in the vehicle front-rear direction.

[0033] The pulley unit 136 is attached to an upper end 142 of the guide rail 132, and the wire 144 is wound around it. The motor unit 138 is located at a lower end 146 of the guide rail 132 as shown in Fig. 2, and has a regulator motor 148 and a drum 150. The motor unit 138 raises and lowers the carrier plate 134 on the guide rail 132 via the wire 144 by the rotational force of the drum 150 rotated by the regulator motor 148.

[0034] 3(a), the carrier plate 134 has a main body 152 and a slide rail 158. The main body 152 is pulled by the wire 144 and slides on the guide rail 132 in the vertical direction.

[0035] The slide rail 158 extends in the longitudinal direction of the vehicle, connects the pair of holders 154, 156, is slidably attached to the main body 152, and slides together with the pair of holders 154, 156 relative to the main body 152 in the longitudinal direction of the vehicle.

[0036] The slide rail 158 includes a side wall 160 extending in the front-rear direction of the vehicle as shown in Fig. 3(a), and an upper wall 162 and a lower wall 164 as shown in Fig. 3(b). The upper wall 162 is a wall that is bent from an upper edge 166 of the side wall 160 toward the outside of the vehicle. The upper wall 162 is formed with an upper protrusion 168 that protrudes upward in the front-rear direction of the vehicle. The lower wall 164 is a wall that is bent from a lower edge 170 of the side wall 160 toward the outside of the vehicle. The lower wall 164 is formed with a lower protrusion 172 that protrudes downward in the front-rear direction of the vehicle.

[0037] The carrier plate 134 further has a first fixing portion 174, a second fixing portion 176, and a recess 178. The first fixing portion 174 is provided on the main body 152 as shown in FIG. 3(a), and fixes one end 144a of the wire 144 wound around the pulley portion 136. The second fixing portion 176 is provided on the main body 152 as shown in FIG. 3(b), and fixes the other end 144b of the wire 144. The other end 144b of the wire 144 is wound around the drum 150 of the motor unit 138 shown in FIG. 2 and extends along the guide rail 132.

[0038] 3(b), the recess 178 is a portion formed by recessing the main body 152 toward the vehicle interior. An upper groove 180 and a lower groove 182 are provided in the recess 178. The upper groove 180 and the lower groove 182 respectively hold the upper protrusion 168 and the lower protrusion 172 of the slide rail 158 so that they can slide in the front-rear direction of the vehicle.

[0039] 3(a), the first fixing portion 174 and the second fixing portion 176 are positioned to overlap with the recess 178 (see FIG. 3(b)) in a side view. Furthermore, as shown in FIG. 2, the carrier plate 134 is disposed on the vehicle front side with respect to the center of gravity G, which is the center of the area of ​​the door glass 104.

[0040] For this reason, the positions of the first fixing portion 174 and the second fixing portion 176 set on the main body 152 of the carrier plate 134 are also set on the vehicle front side of the center of gravity G of the door glass 104. In addition, the fitting position of the carrier plate 134 and the guide rail 132 is also set on the vehicle front side of the center of gravity G of the door glass 104.

[0041] Fig. 4 is a diagram showing the behavior of the door glass 104 of the vehicle door structure 100 in Fig. 2 when it is raised or lowered. Fig. 4(a) and Fig. 4(b) respectively show the behavior of the door glass 104 when it is raised by the above-mentioned window regulator 110 and the window regulator 110A of the comparative example.

[0042] Window regulator 110A of the comparative example has carrier plate 134A. Carrier plate 134A differs from carrier plate 134 described above in that it does not have slide rail 158 described above. Therefore, in window regulator 110A of the comparative example, carrier plate 134A can slide up and down on guide rail 132, but cannot slide together with pair of holders 154, 156 in the front-rear direction of the vehicle.

[0043] Therefore, when the door glass 104 is raised by the window regulator 110A of the comparative example, if the obtuse angle portion 130 comes into contact with the front glass run 114 at point B, a downward force indicated by arrow C acts on the obtuse angle portion 130. The door glass 104 is then pushed by the front glass run 114 and rotates counterclockwise around point D as indicated by arrow E. This rotation center D is the fitting position of the carrier plate 134A and the guide rail 132 as shown in the figure. Therefore, when the door glass 104 rotates, only the obtuse angle portion 130 comes into contact with the front glass run 114, and other portions do not come into contact with the glass run.

[0044] In other words, when the door glass 104 is raised or lowered by the window regulator 110A of the comparative example, the door glass 104 contacts the glass run at only one point, and a jamming behavior of the door glass 104 occurs due to the moment balance between the normal force and the frictional force.

[0045] In contrast, the carrier plate 134 shown in Figure 4 (a) has, in addition to a main body 152 that slides vertically on the guide rail 132, a slide rail 158 (see Figure 3) that slides in the fore-and-aft direction of the vehicle relative to the main body 152 together with a pair of holders 154, 156.

[0046] In the vehicle door structure 100, when the door glass 104 rises and the obtuse angle portion 130 comes into contact with the front glass run 114 at point B, a downward force indicated by an arrow C acts on the obtuse angle portion 130. As a result, the door glass 104 is pushed by the front glass run 114, and the slide rail 158 of the carrier plate 134 slides toward the rear of the vehicle relative to the main body 152 together with the holders 154, 156 that hold the door glass 104 (arrow F).

[0047] As a result, the door glass 104 rotates counterclockwise around point H as indicated by arrow I. This rotation center H is at or near the center of gravity G of the door glass 104 shown in FIG. 2. As a result, not only does the obtuse angle portion 130 of the door glass 104 come into contact with the front glass run 114, but the rear lower corner 184 comes into contact with the rear glass run 116 at point J. This rear lower corner 184 is the corner where the rear edge 122 and lower edge 140 of the door glass 104 intersect, and is located diagonally from the obtuse angle portion 130.

[0048] That is, in the vehicle door structure 100, when the obtuse angle portion 130 comes into contact with the front glass run 114 and the door glass 104 rotates during raising and lowering of the door glass 104, the door glass 104 comes into contact with the glass run at two points, the obtuse angle portion 130 and the corner portion 184 diagonally positioned to the obtuse angle portion 130. Therefore, even if the obtuse angle portion 130 of the door glass 104 comes into contact with the front glass run 114, a moment that offsets the catching behavior is generated by the normal force and frictional force generated by the contact between the corner portion 184 at the lower rear end and the rear glass run 116, and the catching behavior of the door glass 104 can be suppressed.

[0049] This prevents the door glass 104 from being pressed hard against the front glass run 114 when the door glass 104 is raised or lowered, causing the front glass run 114 to tear, or prevents the anti-pinch device of the door glass 104 from malfunctioning and reversing erroneously due to an instantaneous decrease in the raising and lowering speed of the door glass 104.

[0050] Furthermore, in the vehicle door structure 100, the main body 152 of the carrier plate 134 is provided with a first fixing portion 174 and a second fixing portion 176 for respectively fixing one end 144a and the other end 144b of the wire 144. Therefore, the main body 152 can slide up and down on the guide rail 132 by being pulled by the wire 144.

[0051] In addition, the slide rail 158 of the carrier plate 134 is held in an upper groove portion 180 and a lower groove portion 182 provided in the recess 178 of the main body 152 so that an upper protrusion portion 168 formed on the upper wall 162 and a lower protrusion portion 172 formed on the lower wall 164 are slidably held in the fore-and-aft direction of the vehicle in the upper and lower groove portions 180 and 182 provided in the recess 178 of the main body 152.

[0052] This allows the slide rail 158 to slide reliably in the vehicle longitudinal direction relative to the main body 152 together with the pair of holders 154, 156, and further prevents the slide rail 158 from falling off. Note that the upper protrusion 168 and the lower protrusion 172 of the slide rail 158 can prevent, for example, rainwater dripping from the door glass 104 from entering the recess 178 of the main body 152. This allows the slide rail 158 to slide more reliably in the vehicle longitudinal direction relative to the main body 152.

[0053] Furthermore, in the main body 152, the first fixing portion 174 and the second fixing portion 176 are positioned so as to overlap the recessed portion 178 in a side view. In other words, the first fixing portion 174 and the second fixing portion 176, to which force is applied via the wire 144 when the door glass 104 is raised and lowered, are positioned so as to overlap the recessed portion 178 in a side view, so that the main body 152 does not rattle when the door glass 104 is raised and lowered, and the posture of the main body 152 is stable. As a result, the main body 152 can slide stably in the up and down direction on the guide rail 132 while keeping the gap 186 with the guide rail 132 shown in FIG. 3(b) constant when the door glass 104 is raised and lowered.

[0054] Furthermore, the positions of the first fixing portion 174 and the second fixing portion 176 and the fitting position of the carrier plate 134 and the guide rail 132 are set on the side of the shorter vertical side of the door glass 104 (the front side of the vehicle) from the center of gravity of the door glass 104. This makes it possible to suppress vibration when the door glass 104 is raised and lowered. If the vehicle door structure 100 is applied to a rear door, the positions of the first fixing portion 174 and the second fixing portion 176 and the fitting position of the carrier plate 134 and the guide rail 132 are set on the side of the shorter vertical side of the door glass (the rear side of the vehicle) from the center of gravity of the door glass of the rear door.

[0055] Therefore, in the vehicle door structure 100, the corner 184 diagonally located to the obtuse angle portion 130 of the door glass 104 reliably contacts the rear glass run 116, generating a moment that offsets the catching behavior, thereby sufficiently suppressing the catching behavior of the door glass 104.

[0056] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
