Description

Technical Field

[0001] This specification discloses a fixing structure of a wire harness for supplying electric power to a window glass mounted on a vehicle. Background Art

[0002] Generally, a vehicle is provided with a window glass covering a window opening. Among the window glasses, there is a window glass in which an electrical component is installed. As the electrical component, for example, an electric heating wire for heating the window glass to remove fogging of the window glass, and a dimming film (such as a liquid crystal film, etc.) for changing the light transmittance of the window glass are equivalent to this.

[0003] For example, a window glass with a heating wire built in is disclosed in Patent Document 1. In Patent Document 1, a bracket (referred to as "end portion 1a" in Patent Document 1) is directly fixed to one surface of the window glass. And a wire harness for power supply is connected to the bracket.

[0007] Problems to be solved by the invention

[0008] However, when a thick bracket is fixed to the surface of the window glass as in Patent Document 1, a strong impact may be applied to the window glass. That is, when the door provided with the window glass is closed, the bracket collides with the door panel or the like or generates a large moment due to the movement of the long wire harness, and receives a strong impact. When the thick bracket is directly fixed to the surface of the window glass, the impact is transmitted from the bracket to the window glass, and the window glass may be broken.

[0009] Therefore, this specification discloses a wire harness fixing structure capable of reducing the impact input to the window glass.

[0010] Means for solving problems

[0011] The wiring harness fixing structure disclosed in this specification is characterized in that it comprises: a vehicle window glass that can be moved forward and backward and is equipped with electrical components; a groove-shaped glass frame groove that receives and holds the edge of the vehicle window glass; a wiring harness that supplies power to the electrical components; and a fixing bracket that is fixed to a single side of the glass frame groove to hold the wiring harness.

[0012] By fixing the fixing bracket to the glass frame groove instead of the window glass, the impact received by the fixing bracket is not easily input to the window glass. As a result, the impact input to the window glass can be reduced.

[0013] In this case, the fixing bracket may include: a main bracket having a substantially flat-plate-shaped joint portion overlapping and joined to a single surface of the glass frame groove and a protrusion protruding outward in the long-axis direction of the glass frame groove; a fixing protector screwed and fastened to the protrusion; and a relay terminal mounted on at least one of the main bracket and the fixing protector to electrically relay the wiring harness and the electrical component.

[0014] By providing a fixing protector, the wire harness can be more appropriately protected. In addition, by providing a relay terminal, the wiring work of the wire harness can be simplified.

[0015] Furthermore, the relay terminal may be located outside the window glass in a plane direction, and neither the main bracket nor the fixing protector may be in direct contact with the window glass.

[0016] By adopting this structure, interference between the relay terminal and the window glass can be prevented, and the impact input to the window glass can be reduced more reliably.

[0017] Furthermore, the window glass may be a side window glass mounted on a side door of a vehicle and may be a laminated glass formed by laminating two or more glass plates, and the electrical element may be a light-adjusting film for adjusting the transmittance of the window glass.

[0018] By installing the fixing bracket in the glass frame groove, laminated glass, which is weaker than tempered glass, can be used for side window glass that is easily impacted. In addition, by using laminated glass, a dimming film can be assembled on the window glass as an electrical component.

[0019] Effects of the Invention

[0020] According to the technology disclosed in this specification, the impact input to the window glass can be further reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Hereinafter, the fixing structure of the wire harness 60 will be described with reference to the drawings. It should be noted that Fr, Up, and Rh in each drawing represent the front, the upper, and the right side of the vehicle, respectively.

[0028] The vehicle window glass 10 is a side window glass assembled to a side door (not shown) of a vehicle. A vehicle window opening is formed at the upper portion of the vehicle's side door, and the vehicle window glass 10 covers the vehicle window opening. In addition, the vehicle window glass 10 is mechanically connected to a lifting mechanism (not shown) to be lifted and lowered, that is, to move forward and backward. When the vehicle window glass 10 is raised, the vehicle window opening is closed, and when the vehicle window glass 10 is lowered, the vehicle window opening is opened. The structure of the lifting mechanism is not particularly limited. For example, the lifting mechanism may be an electric actuator having an electric drive source such as a motor. In addition, as another embodiment, the lifting mechanism may also be a mechanical transmission mechanism that converts the manual operation of the occupant into an up and down movement and transmits it to the vehicle window glass 10. The lifting mechanism is mechanically connected to a glass frame groove 14, for example.

[0029] In this example, a predetermined electrical component 12 is installed in the window glass 10. The electrical component 12 is operated by receiving power supply. The electrical component 12 is not particularly limited. The electrical component 12 may be, for example, an electric heating wire for heating the window glass 10 in order to remove fog from the window glass 10. In addition, the electrical component 12 may be, for example, a dimming film (such as a liquid crystal film) for adjusting the transmittance of the window glass 10. In any case, the electrical component 12 is integrated with the window glass 10.

[0030] The lower edge of the window glass 10 is held by the glass frame groove 14. The glass frame groove 14 is a groove-shaped metal member. More specifically, Figure 4 As shown, the glass frame groove 14 has a pair of side walls 16 and a bottom wall 18 connecting the lower ends of the two side walls 16. The window glass 10 is inserted between the two side walls 16. The two side walls 16 have a little spring property and sandwich the window glass 10.

[0031] like Figure 1As shown, an electrode 64 is attached to the surface of the lower part of the window glass 10. The electrode 64 is electrically connected to the electrical component 12 and receives power supply to the electrical component 12. The power supply line 62 described later is connected to the electrode 64. The electrode 64, the glass frame groove 14 and the fixing bracket 20 described later are all arranged at a position that is invisible to the passengers. That is, even if the window glass 10 is fully raised, the lower part of the window glass 10 is lower than the lower edge L of the window opening. The glass frame groove 14 and the like are arranged on the lower side than the lower edge L of the window opening. Therefore, the glass frame groove 14 and the like are accommodated in the internal space of the door formed between the inner door panel and the outer door panel (both not shown).

[0032] The power supply line 62 is connected to a harness 60. The base end of the harness 60 is held by a fixing member 50 mounted on the vehicle. The harness 60 is electrically connected to a power supply source 70, and supplies power from the power supply source 70 to the electrical component 12. The power supply source 70 is, for example, a vehicle-mounted battery or a generator mounted on the vehicle.

[0033] A fixing bracket 20 for holding the end of the harness 60 is mounted in the glass frame groove 14. The fixing bracket 20 is roughly divided into a main bracket 22 and a fixing protector 36. The main bracket 22 is a metal member joined to the glass frame groove 14. It should be noted that, hereinafter, the direction approaching the center of the thickness direction of the window glass 10 when viewed from the main bracket 22 is referred to as "inner side in the thickness direction", and the direction away from the center of the thickness direction of the window glass 10 is referred to as "outer side in the thickness direction".

[0034] from Figure 4 , Figure 5 As is apparent, the main bracket 22 is a flat plate-shaped member, and is overlapped and joined to the side wall 16 of the glass frame groove 14 . Figure 6 The upper stage of FIG. 1 is a diagram showing the arrangement relationship among the main bracket 22 , the glass frame groove 14 , and the fixing protector 36 . Figure 3 The "×" mark in the figure indicates the joint points 30 between the main bracket 22 and the side wall 16. It should be noted that the number of such joint points 30 is not particularly limited. However, by setting the number of joint points 30 to be 2 or more, the rotation of the main bracket 22 can be effectively prevented.

[0035] A portion of the main bracket 22 protrudes outward in the long axis direction of the glass frame groove 14. Hereinafter, the protruding portion is referred to as a "protruding portion 26", and the portion overlapping the side wall 16 is referred to as a "joining portion 24". The tip of the protruding portion 26 is a generally circular shape that bulges downward. A fastening hole 28 for fastening a fixing protector 36 is formed at the center of the circular portion. In addition, a nut 38 is fixed to the back of the main bracket 22 in a concentric manner with the fastening hole 28.

[0036] like Figure 2 and Figure 6As shown in the upper stage of FIG. 1 , the fixing protector 36 is a member fastened to the protruding portion 26 in a state overlapped with the outer side in the thickness direction of the protruding portion 26. The fixing protector 36 is a substantially flat plate-shaped member made of, for example, resin.

[0037] The relay terminal 39 is a member that electrically connects the power supply line 62 and the harness 60. The relay terminal 39 includes, for example, a relay line 40 connected to the harness 60, a first connector 42, and a second connector 43.

[0038] Here, the main bracket 22 is joined to the outer side of the side wall 16 in the thickness direction, and the fixing protector 36 is fastened to the outer side of the main bracket 22 in the thickness direction. Therefore, the main bracket 22 and the fixing protector 36 are both separated from the window glass 10 in terms of position. Figure 2 As shown in FIG. 1 , the relay terminal 39 including the connectors 42 and 43 is arranged outside the surface direction of the window glass 10. Therefore, the main bracket 22, the fixing protector 36, and the relay terminal 39 are not in direct contact with the window glass 10 in the thickness direction. As a result, the impact in the thickness direction applied to the main bracket 22 and the fixing protector 36 is not easily transmitted to the window glass 10.

[0039] Next, the reason for providing the above-mentioned fixed bracket 20 is explained. First, consider a case where the wire harness 60 is directly connected to the power supply line 62 from the fixed component 50 without being held in the middle. In this case, the tension of the power supply line 62 changes with the raising and lowering of the window glass 10, so the power supply line 62 is easily deteriorated. In addition, in this case, the load of the wire harness 60 acts on the power supply line 62 and then the electrode 64, which easily causes the electrode 64 and the power supply line 62 to deteriorate. Therefore, in the past, a fixed bracket for holding the wire harness 60 has been proposed. However, the previous fixed bracket is directly mounted on the surface of the window glass 10 instead of the glass frame groove 14. In this case, there is a problem that the impact applied to the fixed bracket is easily transmitted to the window glass 10.

[0040] That is, as described above, the lower part of the window glass 10 and the fixing bracket fixed to the lower part are located in the inner space of the door. In this state, if the door is closed forcefully, a large impact is applied to the fixing bracket in the glass thickness direction. At this time, if the fixing bracket is directly fixed to the window glass 10, the impact received by the fixing bracket is transmitted to the window glass 10 as it is, and the window glass 10 may be broken.

[0041] In order to avoid such a problem, it is also possible to consider making the window glass 10 a tempered glass. However, when a dimming film is installed in the window glass 10 as an electrical component 12, the window glass 10 must be a laminated glass formed by bonding a plurality of glass plates via an intermediate film. Therefore, when tempered glass is used, it is impossible to install the dimming film in the window glass 10 as an electrical component 12. That is, in the past, it was difficult to install an electrical component 12, especially a dimming film, in the window glass 10 mounted on an opening or closing object (i.e., a door, etc.).

[0042] On the other hand, in this example, as described above, the fixed bracket 20 is installed in the glass frame groove 14 instead of the window glass 10. In addition, as described above, the main bracket 22, the fixed protector 36 and the relay terminal 39 are not in direct contact with the window glass 10 in the thickness direction. As a result, the impact in the thickness direction applied to the main bracket 22, the fixed protector 36 and the relay terminal 39 is not easily transmitted to the window glass 10. As a result, according to this example, the electrical component 12 can be well loaded into the window glass 10 mounted on the opening and closing object. It should be noted that the electrode 64 is sufficiently thin and is located on the inner side of the main bracket 22 in the thickness direction. Therefore, when the door is closed, the electrode 64 will not collide with the door component.

[0043] In addition, in this example, the joint portion 24 of the main bracket 22 is formed into a substantially flat plate shape. By forming such a structure, the protrusion amount of the main bracket 22 from the glass frame groove 14 can be suppressed to be small. The protrusion amount in the thickness direction can be suppressed to be small. As a result, the thickness of the entire vehicle window glass 10 after assembling and fixing the bracket 20 can be suppressed to be small, and the workability when inserting the vehicle window glass 10 into the vehicle door opening can be maintained high.

[0044] In addition, the relay terminal 39 including the connectors 42 and 43 is thick. By arranging the thick relay terminal 39 outside the surface direction of the window glass 10, the overall thickness of the window glass 10 after assembling the fixing bracket 20 can be suppressed while suppressing interference between the relay terminal 39 and the window glass 10.

[0045] It should be noted that the structures described so far are examples, and other structures may also be changed as long as they have the structure of claim 1. For example, as long as the fixing bracket 20 is installed in the glass frame groove 14, its structure may be appropriately changed. For example, the fixing bracket 20 may also be a structure having a main bracket 22 but not having a fixing protector 36. In addition, in this example, the side window glass mounted on the side door is used as an example for description, but the technology disclosed in this specification may also be applied to other window glasses 10 mounted on the vehicle and moving forward and backward. For example, the technology disclosed in this specification may also be applied to window glasses 10 for sunroofs that can be opened and closed.

[0046] In addition, the shape of the main bracket 22 can also be appropriately changed. For example, the main bracket 22 is not limited to a flat plate. Figure 6 As shown in the lower section of , it can also be a crank shape that is bent in a step-like manner in the thickness direction in the middle. In this case, the end of the main bracket 22 is bent in the direction close to the window glass 10 (i.e., the inner side in the thickness direction). By forming it into this structure, the protrusion amount of the fixing protector 36 from the window glass 10 can be suppressed to be small. And, thereby, the connection part 41 of the wire harness 60 and the relay line 40 can be arranged on the outside in the thickness direction. Here, the operator works from the outside in the thickness direction, so by arranging the connection part 41 on the outside in the thickness direction, the workability of wiring can be improved.
