Abstract
Description
Vehicle handle device, vehicle door, vehicle, and method for manufacturing vehicle handle device
[0001] The present invention relates to a vehicle handle device, a vehicle door, a vehicle, and a method for manufacturing a vehicle handle device.
[0002] Patent Document 1 discloses a vehicle handle device including a vehicle door handle, a resin bracket (handle support member) that supports the handle, and a metal spacer. The spacer has a cylindrical portion and a flange portion that protrudes from an end of the cylindrical portion. A through hole is formed in the bracket, and the cylindrical portion of the spacer is fitted into this through hole. The bracket, together with the spacer, is attached to the inside of the outer panel of the vehicle door.
[0003] JP 2017-101408 A
[0004] In the vehicle handle device disclosed in Patent Document 1, the spacer is sometimes removed from the bracket and reassembled during vehicle assembly or maintenance. When this occurs, the spacer rubs against the bracket, causing material fragments, such as resin fragments, to be generated from the bracket. If these material fragments become trapped between the spacer and other components, the bracket may become misaligned relative to the outer panel of the vehicle door, reducing the positional accuracy of the outer surface of the handle body relative to the outer surface of the outer panel.
[0005] The present invention has been made in light of the above-mentioned circumstances, and has an object to suppress a decrease in the accuracy of the position of the outer surface of a handle body relative to the outer surface of an outer panel of a vehicle door.
[0006] In order to achieve the above-mentioned object, the present invention provides a vehicle handle device in which a handle body is fixed inside a vehicle door composed of an outer panel and an inner panel, the vehicle handle device comprising: an intermediate panel disposed between the outer panel and the inner panel; a bracket having a through hole formed therein for fixing the handle body to the intermediate panel; a collar portion disposed in the through hole of the bracket; and a position adjustment function portion fitted into the through hole and disposed between the collar portion and the intermediate panel for positioning the outer surface of the handle body relative to the outer surface of the outer panel. The vehicle handle device is characterized by having a gap between the bracket and the position adjustment function portion.
[0007] According to the present invention, the vehicle handle device has a gap between the bracket and the position adjustment feature. Therefore, even if a piece of material is generated when at least one of the collar and the position adjustment feature is fitted into the through-hole, the piece of material enters the gap. Therefore, the piece of material is less likely to become trapped between the collar and the position adjustment feature. As a result, it is possible to prevent a decrease in the positional accuracy of the outer surface of the handle body relative to the outer surface of the outer panel of the vehicle door.

[0009] A vehicle handle device 1, a vehicle door 90, and a vehicle 100 equipped with the same according to an embodiment will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates are set and referenced as appropriate. As shown in FIG. 1 , the X-axis direction of the XYZ coordinates is the width direction of the vehicle 100, the Y-axis direction is the front-rear direction, and the Z-axis direction is the height direction. In addition, in each drawing, the same reference numerals indicate the same or corresponding parts.
[0010] 1, the vehicle 100 includes a vehicle body, front wheels T1, rear wheels T2, an engine, a vehicle door 90, and other automobile components. The vehicle 100 is, for example, an automobile equipped with a gasoline engine for driving the front wheels T1. However, the vehicle 100 is not limited to this. The vehicle 100 may be an automobile other than an automobile equipped with a gasoline engine.
[0011] 1 and 2, in this embodiment, the vehicle door 90 is a left side front door of the vehicle 100. The vehicle door 90 is attached to the vehicle body so as to be openable and closable around an axis parallel to the height direction of the vehicle 100. The vehicle door 90 includes a panel 91 which is an outer panel, an inner panel, a panel 92 which is an intermediate panel, and a vehicle handle device 1 provided with a door handle 93 (handle main body).
[0012] The panel 91 is an outer panel of the vehicle body. As shown in Fig. 1, the panel 91 is provided with a windshield and side mirrors. As shown in Fig. 2, the panel 91 is also formed with a hole 91a through which a door handle 93 passes.
[0013] The panel 92 is an intermediate panel disposed between the panel 91, which is an outer panel, and the inner panel. The panel 92 is also formed with a hole 92a through which the door handle 93 passes. The vehicle handle device 1 is fixed to the panel 92 from the inside of the vehicle.
[0014] 1 and 2, the door handle 93 is a handle body that is used by a user to open and close the vehicle door 90. The door handle 93 is disposed such that its surface is exposed to the outside of the vehicle body through a hole 91a formed in the panel 91 and a hole 92a formed in the panel 92.
[0015] 3, when the door handle 93 is not in use by the user, it is moved toward the rear (toward the interior of the vehicle) and positioned so that the difference in surface area between its outer surface 93a and the outer surface 91b of the outer panel 91 is small. By reducing the difference in surface area between the outer surface 93a of the door handle 93 and the outer surface 91b of the panel 91, the aesthetic appearance of the vehicle is improved when the door handle 93 is not in use.
[0016] As shown in Figures 2 and 3, the vehicle handle device 1 has a bracket 10, which is fixed to a panel 92 by a bolt 30 and a nut 40 via a collar portion 21 and a position adjustment function portion 22.
[0017] As shown in FIG. 2 , the bracket 10 is provided with a door handle 93, and an electronic unit 60 for controlling the door handle 93 is provided inside the vehicle. The bracket 10 also has three through holes 10a formed therein: above and below the door handle 93, and on the front side of the vehicle. The three through holes 10a are for fastening the bracket 10 to a panel 92 with bolts 30 and nuts 40, and all have the same structure. A collar portion 21 and a position adjustment function portion 22 are fitted into each of the through holes 10a. In this embodiment, the bracket 10 is formed with three through holes 10a. However, this is not limited to this. Two or fewer through holes 10a may be formed, or four or more through holes 10a may be formed.
[0018] As shown in Fig. 3, the bracket 10 is disposed at a predetermined distance (clearance C) from the interior surface (one surface) of the vehicle door panel 92. The bracket 10 is made of resin. Specifically, the bracket 10 is made of a nylon-based resin. However, this is not a limitation. The bracket 10 may be made of a resin other than nylon-based resin. The bracket 10 is formed with a through-hole 10a having a circular YZ cross section.
[0019] As shown in Fig. 4, each through hole 10a is formed to penetrate in the X-axis direction. Each through hole 10a has a large diameter portion 12, a small diameter portion 13, and a step 15. Note that the cross sections shown in Fig. 4 and subsequent cross sections correspond to the cross section taken along the arrow A-A in Fig. 2, similar to Fig. 3.
[0020] The large diameter portion 12 has a circular cross section and is formed near the opening of the through hole 10a on the −X side (inside the vehicle).
[0021] The small diameter portion 13 has a circular cross section. The small diameter portion 13 is formed to have a smaller diameter than the large diameter portion 12. The small diameter portion 13 is formed near the opening on the +X side (vehicle exterior) of the through hole 10a. In addition, a protrusion 10b that protrudes inward is formed on the inner circumferential surface of the small diameter portion 13. The protrusion 10b is a retaining rib for retaining the position adjustment function portion 22. For example, three protrusions 10b are formed at equal intervals around the central axis of the through hole 10a. However, this is not limited to this. A number other than three protrusions 10b may be formed. The protrusions 10b are formed to fix the position adjustment function portion 22.
[0022] The step 15 is formed between the large diameter portion 12 and the small diameter portion 13 .
[0023] 3 to 5, the collar portion 21 and the position adjustment function portion 22 are disposed in a through hole 10a formed in the bracket 10. The collar portion 21 and the position adjustment function portion 22 are provided to form a clearance C (see FIG. 3) between the panel 92 and the bracket 10.
[0024] The collar portion 21 is a component that is placed in the through-hole 10a of the bracket 10 from the -X side (the vehicle interior side). The collar portion 21 is made of metal. For example, the collar portion 21 is made of iron. The collar portion 21 is a cylindrical component that includes a cylindrical portion 21a. In the present embodiment, the collar portion 21 is illustrated as a cylindrical component, but is not limited to this. The collar portion 21 may also be a cylindrical component other than a cylindrical component. The collar portion 21 formed in this manner is fixed to the bracket 10 by being press-fitted into the through-hole 10a.
[0025] 4, the length L1 of the collar portion 21 in the X-axis direction is shorter than the length L3 of the large diameter portion 12 in the X-axis direction (L1<L3). Therefore, as shown in FIGS. 3, 6A, and 6B, when the collar portion 21 is press-fitted into the through-hole 10a, the collar portion 21 is fitted away from the step 15. In this embodiment, the rear end surface 21d of the collar portion 21 is located on the same plane as the end surface of the bracket 10. Note that when the metal collar portion 21 is press-fitted into the resin bracket 10, resin pieces P1 may be generated from the bracket 10.
[0026] The position adjustment function part 22 is a cylindrical part that is fitted into the through hole 10a of the bracket 10 from the +X side. In this embodiment, the position adjustment function part 22 is illustrated as a cylindrical part, but is not limited to this. The position adjustment function part 22 may be a cylindrical part other than a cylindrical part. The position adjustment function part 22 is formed of metal. For example, the position adjustment function part 22 is formed of iron. As shown in FIGS. 6C and 6D , the position adjustment function part 22 is pushed into the through hole 10a from the +X side (the vehicle exterior side) and fitted into the small diameter portion 13 of the through hole 10a while crushing the protrusion 10b of the bracket 10. The position adjustment function part 22 may be fitted into the small diameter portion 13 of the through hole 10a and then welded to the protrusion 10b. The position adjustment function part 22 fitted into the through hole 10a abuts against the tip surface 21c of the collar part 21. When the metallic position adjustment function part 22 is fitted into the resin bracket 10, resin pieces P2 may be generated from the bracket 10.
[0027] As shown in FIG. 6B , the length L2 of the position adjustment function portion 22 in the X-axis direction is longer than the length L4 from the tip surface 21c of the collar portion 21 fitted into the bracket 10 to the opening of the through-hole 10a (L2 > L4). Therefore, as shown in FIG. 6D , a portion of the position adjustment function portion 22 protrudes from the bracket 10. The position adjustment function portion 22 is disposed between the collar portion 21 and the panel 92 to position the bracket 10 from the inner surface of the panel 92. Specifically, as shown in FIG. 7 , a plurality of position adjustment function portions 22 having the same outer and inner diameters but different lengths L2, L2-2, and L2-3 in the X-axis direction are prepared in advance. By selecting from the plurality of position adjustment function portions 22 with different lengths L2, L2-2, and L2-3, the clearance C (see FIG. 3 ) between the panel 92 and the bracket 10 is adjusted. As shown in FIG. 6D , the protruding portion 23 of the position adjustment function portion 22 is equivalent to the desired clearance C (see FIG. 3 ). As a result, as shown in FIG. 3 , the position adjustment function unit 22 can position the bracket 10 with a predetermined clearance C from the inner surface of the panel 92. Consequently, the position adjustment function unit 22 can position the outer surface 93a of the door handle 93 relative to the outer surface 91b of the panel 91. In this embodiment, the position adjustment function unit 22 is formed in a cylindrical shape. Specifically, as shown in FIG. 4 , the position adjustment function unit 22 is formed in a cylindrical shape having an inner diameter D2 that is smaller than the inner diameter D1 of the cylindrical portion 21a of the collar portion 21. Furthermore, the position adjustment function unit 22 is formed such that the axial length L2 of the cylindrical shape is longer than the axial length L1 of the collar portion 21.
[0028] 3, a gap 50 is formed between the bracket 10 and the collar portion 21 and the position adjustment function portion 22 formed as described above. The gap 50 is formed in an annular shape around the outer periphery of the position adjustment function portion 22.
[0029] The bolt 30 has a shaft portion with a male thread formed on the outer periphery and a head portion formed at the end of the shaft portion. The shaft portion of the bolt 30 is inserted into the through hole 10a. In this embodiment, the bolt 30 is a weld bolt that is fixed to the panel 92 by welding. However, this is not limited to this. The bolt 30 may be a bolt other than a weld bolt. For example, the bolt 30 may be a general hexagon bolt. The bolt 30 is inserted into a hole formed in the panel 92 and screwed into the nut 40.
[0030] The nut 40 has a screw hole with a female thread formed on the inner periphery. The nut 40, together with the bolt 30, fixes the bracket 10, the collar portion 21, and the position adjustment function portion 22 to the panel 92. In this way, the vehicle handle device 1 is fixed to the panel 92.
[0031] 7, the position adjustment function portion 22 disposed in the through hole 10a may be replaced in order to adjust the clearance C to an appropriate value. The resulting resin or metal pieces are also accommodated in the gap 50.
[0032] Next, a method for manufacturing the vehicle handle device 1 configured as described above will be described with reference to the drawings.
[0033] 6A and 6B , a worker manufacturing the vehicle handle device 1 presses the collar portion 21 into the through-hole 10a of the bracket 10 from the +X side. At this time, a resin piece P1 generated by the press-fitting moves in the +X direction. The resin piece P1 also falls due to gravity.
[0034] Next, as shown in FIGS. 6C and 6D , the worker fits the position adjustment function part 22 into the through hole 10a of the bracket 10 from the -X side. At this time, a resin piece P2 that is created as the position adjustment function part 22 is fitted moves in the -X direction. As the position adjustment function part 22 is fitted, it eventually comes into contact with the collar part 21. As the position adjustment function part 22 comes into contact with the collar part 21, a gap 50 is formed between the bracket 10 and the collar part 21 and the position adjustment function part 22. More specifically, the gap 50 is formed by the outer periphery of the position adjustment function part 22, the inner wall of the through hole 10a of the bracket 10, the tip surface 21c of the collar part 21, and the step 15 of the bracket 10. Then, the resin piece P2 is pushed into the gap 50 together with the resin piece P1. The resin piece P2 also falls due to gravity.
[0035] 2 and 3, the worker fixes the bracket 10, with the collar portion 21 and the position adjustment function portion 22 fitted into the through-hole 10a, to the panel 92 by screwing the bolt 30 into the nut 40. In addition, by selecting an appropriate length of the position adjustment function portion 22, the worker adjusts the clearance C to reduce the surface difference between the outer surface 93a of the door handle 93 and the outer surface 91b of the panel 91. With the above steps, the vehicle handle device 1 is completed.
[0036] As described above, in this embodiment, as shown in Fig. 3, a gap 50 is formed between the bracket 10, the collar portion 21, and the position adjustment function portion 22. As a result, even if a material chip is generated when fitting the collar portion 21 or the position adjustment function portion 22 into the through-hole 10a, the material chip enters the gap 50, making it less likely for the material chip to become caught between the collar portion 21 and the position adjustment function portion 22. As a result, it is possible to prevent a decrease in the positional accuracy of the outer surface 93a of the door handle 93 relative to the outer surface of the panel 91 of the vehicle door 90.
[0037] In this embodiment, the gap 50 is formed on the outer periphery of the position adjustment function portion 22. Therefore, both the resin piece P1 generated between the bracket 10 and the collar portion 21 and the resin piece P2 generated between the bracket 10 and the position adjustment function portion 22 can easily enter the gap 50. This makes it difficult for the resin pieces P1 and P2 to become caught between the collar portion 21 and the position adjustment function portion 22. As a result, it is possible to prevent a decrease in the positional accuracy of the outer surface 93a of the door handle 93 relative to the outer surface 91b of the panel 91 of the vehicle door 90.
[0038] 4, in this embodiment, the position adjustment function part 22 is formed to be longer than the length L1 of the collar part 21 in the X-axis direction. This makes it easier to ensure a large contact area S1 (see FIG. 8) of the position adjustment function part 22 with respect to the bracket 10 compared to when the lengths L2, L2-2, and L2-3 of the position adjustment function part 22 are shorter than the length L1 of the collar part 21. This makes it possible to firmly fix the position adjustment function part 22 to the bracket 10.
[0039] In this embodiment, the position adjustment function unit 22 is formed in a cylindrical shape with an inner diameter D2 that is smaller than the inner diameter D1 of the cylindrical shape of the collar part 21 (D2<D1). This makes it easier to ensure the contact area S2 (see FIG. 8 ) of the position adjustment function unit 22 with the collar part 21 even if the position adjustment function unit 22 shifts relative to the collar part 21 in a direction perpendicular to the X-axis direction (a direction including the Y-axis direction and the Z-axis direction). This allows for stable installation of the position adjustment function unit 22 with respect to the collar part 21.
[0040] In addition, in this embodiment, as shown in FIGS. 6A to 6D, the gap 50 can be formed simply by assembling the position adjustment function portion 22 and the collar portion 21 to the bracket 10.
[0041] In this embodiment, the bracket 10, the collar portion 21, and the position adjustment function portion 22 are fixed to the panel 92 by threading the bolt 30 into the nut 40. This improves the efficiency of the work of adjusting the position of the bracket 10 relative to the panel 92. This in turn prevents a decrease in the accuracy of the position of the outer surface 93a of the door handle 93 relative to the outer surface 91b of the panel 91 of the vehicle door 90.
[0042] In this embodiment, the bracket 10 is made of resin, and the collar portion 21 and the position adjustment function portion 22 are made of metal. Therefore, the material pieces that are likely to be generated when the position adjustment function portion 22 is fitted into the through-hole 10a are resin or metal pieces. The resin or metal pieces then enter the gap 50. This makes it difficult for material pieces to become trapped between the collar portion 21 and the position adjustment function portion 22. This makes it possible to prevent a decrease in the positional accuracy of the outer surface 93a of the door handle 93 relative to the outer surface 91b of the panel 91 of the vehicle door 90.
[0043] 6A to 6D, in this embodiment, resin piece P1, which is generated when collar portion 21 of through hole 10a is press-fitted, is moved in one direction. Also, resin piece P2, which is generated when position adjustment function portion 22 of through hole 10a is fitted, is moved in the other direction. As a result, in this embodiment, resin pieces P1 and P2 can be pressed into gap 50 while forming gap 50.
[0044] Although the present embodiment has been described above, the present invention is not limited to the above embodiment.
[0045] For example, in this embodiment, the vehicle handle device 1 is attached to the panel 92, which is an intermediate panel, as shown in Fig. 3. However, this is not limiting. The vehicle handle device 1 may be attached to the panel 91, which is an outer panel, or to an inner panel.
[0046] 1 and 2, in this embodiment, the vehicle door 90 equipped with the vehicle handle device 1 is a left side front door of the vehicle 100. However, this is not limited thereto. The vehicle door 90 equipped with the vehicle handle device 1 may be a right side front door. Furthermore, the vehicle door 90 may be a rear door or a back door.
[0047] In the present embodiment, the vehicle handle device 1 is fixed to the panel 92 by the bolts 30 and the nuts 40. However, this is not limited to this. The vehicle handle device 1 may be fixed to the panel 92 by a fastener other than the bolts 30 and the nuts 40. For example, the vehicle handle device 1 may be fixed to the panel 92 by a fastener such as a rivet.
[0048] In the present embodiment, as shown in Fig. 3 , the gap 50 is formed on the outer periphery of the position adjustment function part 22. However, this is not limited to this. As in the vehicle handle device 2 according to a modified example shown in Fig. 9 , the gap 50 may be formed on the outer periphery of the collar part 21. However, as shown in Fig. 3 , from the viewpoint of making it easier for both a resin piece P1 generated between the bracket 10 and the collar part 21 and a resin piece P2 generated between the bracket 10 and the position adjustment function part 22 to enter, it is preferable that the gap 50 be formed on the outer periphery of the position adjustment function part 22.
[0049] In the present embodiment, the gap 50 is formed in a ring shape on the outer periphery of the position adjustment function part 22. However, this is not limiting. The gap 50 may be formed in a shape other than a ring. For example, the gap 50 may be formed in at least a part of the outer periphery of the position adjustment function part 22, such as the lower end part.
[0050] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. Furthermore, the above-described embodiments are intended to explain the present invention and do not limit the scope of the present invention. In other words, the scope of the present invention is defined by the claims, not by the embodiments. Various modifications made within the scope of the claims and the meaning of the disclosure equivalent thereto are considered to be within the scope of the present invention.
