Description

Fixing structure of wire harness

Technical Field

Disclosed is a structure for fixing a wire harness for supplying electric power to a window glass mounted on a vehicle.

Background

In general, a window glass covering a window opening is provided in a vehicle. Among the window panes, there is a window pane incorporating an electric element. As the electric element, for example, an electric wire for heating the window glass for eliminating the fog of the window glass, and a light control film (for example, a liquid crystal film or the like) for changing the light transmittance of the window glass are equivalent.

For example, patent document 1 discloses a window glass in which an electric wire is incorporated. In patent document 1, a bracket (referred to as "end 1a" in patent document 1) is directly fixed to one surface of a window glass. A wire harness for power supply is connected to the bracket.

Disclosure of Invention

Problems to be solved by the invention

However, in the case where a bracket having a thickness 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 with the movement of the long wire harness, and receives a strong impact. If the bracket having a thickness 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.

Accordingly, in the present specification, a fixing structure of a wire harness capable of reducing an impact input to a window glass is disclosed.

Means for solving the problems

The wire harness fixing structure disclosed in the present specification is characterized by comprising a window glass which can be moved forward and backward and into which an electric component is incorporated, a groove-shaped glass frame groove which receives and holds the edge of the window glass, a wire harness which supplies electric power to the electric component, and a fixing bracket which is fixed to one side of the glass frame groove and holds the wire harness.

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.

In this case, the fixing bracket may include a main bracket having a substantially flat plate-shaped joint portion overlapping and joined to one surface of the glass frame groove and a protruding portion protruding outward in the longitudinal direction of the glass frame groove, a fixing protector screwed to the protruding portion, and a relay terminal attached to at least one of the main bracket and the fixing protector for electrically relaying the wire harness and the electric component.

By providing the protector for fixation, the wire harness can be more suitably protected. In addition, by providing the relay terminal, the wiring work of the wire harness can be simplified.

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

With this configuration, 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.

The window glass may be a side window glass mounted on a side door of a vehicle, and the laminated glass may be a laminated glass in which 2 or more glass plates are laminated, and the electric element may be a light control film for controlling transmittance of the window glass.

By attaching the fixing bracket to the glass frame groove, laminated glass having lower strength than reinforced glass can be used for side window glass which is easy to generate impact. In addition, by using a laminated glass, a light control film can be assembled to a window glass as an electrical element.

Effects of the invention

According to the technology disclosed in the present specification, the impact input to the window glass can be further reduced.

Detailed Description

Hereinafter, a fixing structure of the wire harness 60 will be described with reference to the drawings. In each of the drawings, fr, up, rh represent the front, upper, and right sides of the vehicle, respectively.

The window glass 10 is a side window glass that is assembled to a side door (not shown) of a vehicle. A window opening is formed in an upper portion of a side door of the vehicle, and a window glass 10 covers the window opening. The window glass 10 is mechanically coupled to a lifting mechanism (not shown) to lift, i.e., advance and retreat. The window opening is closed by the window glass 10 being raised, and the window opening is opened by the window glass 10 being lowered. The structure of the lifting mechanism is not particularly limited, and for example, the lifting mechanism may be an electric actuator having an electric drive source such as a motor. Alternatively, the lifter mechanism may be a mechanical transmission mechanism that converts manual operation of the occupant into vertical movement and transmits the vertical movement to the window glass 10. The lifting mechanism is mechanically coupled to the glass frame 14, for example.

In this example, a predetermined electric element 12 is incorporated in the window glass 10. The electric element 12 is operated by receiving the electric power supply. The electric element 12 is not particularly limited. The electric element 12 may be, for example, an electric wire that heats the window glass 10 to remove mist from the window glass 10. The electric element 12 may be, for example, a light control film (e.g., a liquid crystal film) for adjusting the transmittance of the window glass 10. In any event, the electrical component 12 is integral with the glazing 10.

The lower edge of the window glass 10 is held by the glass bezel 14. The glass bezel 14 is a groove-shaped metal member. More specifically, as shown in fig. 4, the glass bezel 14 has a pair of side walls 16 and a bottom wall 18 connecting lower ends of the two side walls 16. The window pane 10 is interposed between the two side walls 16. The two side walls 16 have a slight spring property and hold the window glass 10.

As shown in fig. 1, an electrode 64 is adhered to the surface of the lower portion of the window glass 10. The electrode 64 is electrically connected to the electric element 12, and receives power supply to the electric element 12. A power supply line 62 described later is connected to the electrode 64. The electrode 64, the glass bezel 14, and the fixing bracket 20 described later are disposed at positions not visible to the occupant. That is, even if the window glass 10 is completely raised, the lower portion of the window glass 10 is lower than the lower edge L of the window opening. The glass bezel 14 and the like are disposed below the lower edge L of the window opening. Accordingly, the glass bezel 14 and the like are accommodated in a door inner space formed between a door inner panel and a door outer panel (both not shown).

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

A fixing bracket 20 for holding an end of the wire harness 60 is attached to the glass frame groove 14. The fixing bracket 20 is largely divided into a main bracket 22 and a fixing protector 36. The main bracket 22 is a metal member joined to the glass bezel 14. Hereinafter, a direction approaching the center of the window glass 10 in the thickness direction when viewed from the main bracket 22 is referred to as "inner side in the thickness direction", and a direction separating from the center of the window glass 10 in the thickness direction is referred to as "outer side in the thickness direction".

As is apparent from fig. 4 and 5, the main bracket 22 is a flat plate-like member, and is overlapped and joined with the side wall 16 of the glass bezel 14. The upper stage of fig. 6 is a diagram showing the arrangement relationship of the main bracket 22, the glass bezel 14, and the fixing protector 36. The "x" sign in fig. 3 indicates the junction 30 of the main carrier 22 with the side wall 16. The number of such joints 30 is not particularly limited. However, by setting the joint 30 to 2 or more, the rotation of the main carriage 22 can be effectively prevented.

A part of the main bracket 22 protrudes outward in the longitudinal direction of the glass bezel 14. Hereinafter, the protruding portion will be referred to as "protruding portion 26", and the portion overlapping with the side wall 16 will be referred to as "joint portion 24". The tip of the protruding portion 26 is substantially circular and protrudes downward. A fastening hole 28 for fastening the fixing protector 36 is formed in the center of the circular portion. A nut 38 is fixed concentrically with the fastening hole 28 to the rear surface of the main bracket 22.

As shown in the upper part of fig. 2 and 6, the fixing protector 36 is fastened to the protruding portion 26 in a state of being overlapped on the outer side in the thickness direction of the protruding portion 26. The fixing protector 36 is, for example, a substantially flat plate-like member made of resin.

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

Here, the main bracket 22 is joined to the outer side in the thickness direction of the side wall 16, and the fixing protector 36 is fastened to the outer side in the thickness direction of the main bracket 22. Therefore, the main bracket 22 and the fixing protector 36 are both separated from the window glass 10 in position. As shown in fig. 2, the relay terminal 39 including the connectors 42 and 43 is disposed on the outer side of the window glass 10 in the plane direction. 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 applied to the main bracket 22 and the fixing protector 36 in the thickness direction is not easily transmitted to the window glass 10.

Next, the reason for providing the fixing bracket 20 will be described. First, consider a case where the wire harness 60 is directly connected to the power supply line 62 from the fixing member 50 without being held in the middle. In this case, the tension of the power supply line 62 changes with the lifting of the window glass 10, and therefore the power supply line 62 is liable to deteriorate. In this case, the load of the wire harness 60 acts on the power supply line 62 and the electrode 64, and deterioration of the electrode 64 and the power supply line 62 is likely to occur. Thus, conventionally, a fixing bracket for holding the wire harness 60 has been proposed. However, the conventional fixing bracket is directly attached to the surface of the window glass 10 instead of the glass bezel 14. In this case, there is a problem that the impact applied to the fixing bracket is easily transmitted to the window glass 10.

That is, as described above, the lower portion of the window glass 10 and the fixing bracket fixed to the lower portion are located in the door inner space. In this state, when the door is forcibly closed, 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.

In order to avoid such a problem, it is also conceivable to make the window glass 10 a tempered glass. However, when the light control film is incorporated into the window glass 10 as the electric element 12, the window glass 10 must be a laminated glass in which a plurality of glass plates are bonded via an interlayer film. Therefore, when the tempered glass is used, the light control film cannot be incorporated into the window glass 10 as the electric element 12. That is, it has been difficult to mount the electric element 12, particularly the light control film, on the window glass 10 mounted on an openable and closable object (i.e., a vehicle door or the like).

On the other hand, in this example, as described above, the fixing bracket 20 is attached to the glass bezel 14 instead of the window glass 10. As described above, 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 applied to the main bracket 22, the fixing protector 36, and the relay terminal 39 in the thickness direction is not easily transmitted to the window glass 10. As a result, according to this example, the electric element 12 can be favorably incorporated into the window glass 10 mounted on the opening/closing object. The electrode 64 is sufficiently thin and is located on the inner side in the thickness direction of the main carriage 22. Thus, the electrode 64 does not collide with the door constituting member when the door is closed.

In this example, the joint 24 of the main bracket 22 is formed in a substantially flat plate shape. With this configuration, the amount of protrusion of the main bracket 22 from the glass bezel 14 can be suppressed to be small. The protruding amount in the thickness direction can be suppressed to be small. As a result, the thickness of the entire window glass 10 after the fixing bracket 20 is assembled can be suppressed to be small, and workability in inserting the window glass 10 into the door opening can be maintained to be high.

The relay terminal 39 including the connectors 42 and 43 has a large thickness. By disposing the relay terminal 39 having a large thickness on the outer side in the surface direction of the window glass 10, the thickness of the entire window glass 10 after the fixing bracket 20 is assembled can be suppressed to be small while suppressing interference between the relay terminal 39 and the window glass 10.

The configuration described above is an example, and other configurations may be modified as long as the configuration of claim 1 is provided. For example, the structure of the fixing bracket 20 may be changed as appropriate as long as it is attached to the glass bezel 14. For example, the fixing bracket 20 may have a structure having the main bracket 22 but not having the fixing protector 36. In this example, the side window glass mounted on the side door is described as an example, but the technique disclosed in the present specification can be applied to other window glass 10 mounted on a vehicle and advanced and retracted. For example, the technique disclosed in the present specification can be applied to a window glass 10 for a sunroof that can be opened and closed.

The shape of the main bracket 22 may be changed as appropriate. For example, the main bracket 22 is not limited to a flat plate shape, and may be a crank shape bent stepwise in the thickness direction halfway as shown in the lower stage of fig. 6. In this case, the distal end of the main bracket 22 is bent in a direction approaching the window glass 10 (i.e., inward in the thickness direction). By forming this structure, the protruding amount of the fixing protector 36 from the window glass 10 can be suppressed to be small. In this way, the connection portion 41 between the wire harness 60 and the relay wire 40 can be arranged on the outer side in the thickness direction. Here, since the worker performs work from the outside in the thickness direction, the workability of wiring can be improved by disposing the connection portion 41 on the outside in the thickness direction.
