Description

[Detailed Description of the Invention] [Industrial Application Fields] This invention enables the functions of functional parts to be inspected before assembly, and improves assembly workability. This invention relates to an automobile door that is easy to assemble and has an improved method of wiring a harness inside the door.

[Prior Art] Conventionally, an automobile door has an outer shape formed by an outer panel and an inner panel, and various functional parts are inserted into the space formed by the two through working holes formed in the inner panel. It's assembled.

Various functional parts include a device that raises and lowers the window panel, a device that locks the door, and the like.

When assembling a door lock or a knob-integrated inside handle of a door locking device to an inner panel, the stroke has to be adjusted to prevent malfunctions caused by variations in the accuracy of the inner panel, connecting rod, etc.

On the other hand, there are five types of harnesses traditionally installed inside automobile doors: door lock systems (actuator, knob switch, latch switch, keyless entry, handle switch, and key lighting lamp), and regulator systems (two types). (regulator motor and operation switch) and four other types (back lamp, door mirror switch, speaker, and seat control switch).

Among these, the most common are door lock harnesses, and the wiring of these harnesses is handled on the inner panel side of the door.

[Problems to be Solved by the Invention] However, in such conventional automobile doors, after the functional parts are installed through the work holes, their functions must be confirmed, and each individual item must be checked. It was not possible to confirm the situation. In addition, since each functional component has a different direction, assembly through the working hole has poor productivity in terms of work, adjustment work, quality confirmation, etc. As mentioned above, the structure of the door leads to complicated assembly and malfunction of the door, which not only makes it impossible to achieve automation, but also hinders improvements in vehicle productivity and cost reduction.

In addition, when adjusting the stroke of the connecting rod, etc., especially in the case of a hardtop type door, the distance between the door lock and the inside handle is longer than that of a sedan type, so the operating direction of the connecting rod is adjusted via a bell crank in the middle of the connecting rod. I'm converting. Therefore, the stroke adjustment work was even more difficult.

In order to reduce such work and improve quality, there are examples of wires being used instead of connecting rods. According to this, if the wires are connected and adjusted to the door lock and the inside handle in advance, assembly to the door can be performed without being affected by variations in the inner panel.

However, when assembling such a door lock device to a door, one of the inside handle side or the door lock side hangs down via a wire, which can damage the inner panel and make it inconvenient to handle. be. Further, although assembly reduces the number of man-hours, it is impossible to employ automatic assembly for the reasons mentioned above, and there is a limit to productivity improvement.

Moreover, it is troublesome to arrange a plurality of harnesses and route them inside the door, and there is a risk that the harnesses may interfere with and damage the window panels that move up and down.

Therefore, this invention makes it possible to inspect the functions of functional parts before assembly, and also simplifies the assembly work and improves work efficiency when installing door locks, inside handles, etc. It is an object of the present invention to provide an automobile door that can improve the performance of the vehicle, prevent damage to the inner panel, facilitate wiring of a harness, and prevent damage.

[Means for Solving the Problems] The present invention has been made by focusing on the conventional problems, and provides an automobile door in which an inner panel and an outer panel are assembled from the thickness direction of the door with a frame member in between. The automobile door is constructed by mounting panel lifting means for raising and lowering the window panel and locking means for locking the door to the vehicle body on the frame member, and the locking means includes an inside bracket to which the inside handle is mounted. , has a door lock-side bracket to which the door lock is attached, and a connecting bracket that connects both brackets, connects the inside handle and the door lock with a wire, and further connects the door lock to the connecting bracket from the inside handle side. The vehicle door is characterized by having an insertion portion through which a harness that extends to the side is inserted.

[Operation] According to this method, the functions of the panel lifting means, locking means, etc. are checked in advance before the door is assembled.

Then, using the outer panel or inner panel as a reference,
By sequentially assembling the frame members, etc. equipped with panel elevating means and locking means, one on top of the other,
Complete the door assembly.

By assembling in this way, there is no need to arrange functional parts through conventional work holes, making assembly easy, and the assembly can be done in the overlapping direction, making automatic assembly possible. .

In addition, when assembling the locking means to the frame member, the inside side bracket and the door lock side bracket are connected via the connecting bracket, so the door lock or inside handle does not hang down as in the conventional case. It is convenient to handle and does not damage the inner panel etc. during work.

Moreover, by connecting the door lock and the inside handle with a wire, the function can be inspected while the door lock is still attached to the door.

Furthermore, if the connecting bracket can be gripped by a robot, automatic assembly can be performed.

In addition, by inserting the harness that extends from the inside handle side to the door lock side through the insertion part of the connection bracket, it is possible to easily route multiple harnesses, and the harness can be secured using this connection bracket. This prevents the harness from being damaged by the window panel.
