Description

  The present invention relates to a method for manufacturing a vehicle door.

  Conventional vehicle doors, as described in Patent Document 1, in order to prevent water leakage and the like from the work hole (service opening) opened for assembling parts to the door on the inner panel, etc. A waterproof sheet is fixed to the inner panel.

  In manufacturing the vehicle door by fixing the latch device and the inside handle device connected via the operation force transmission cable to the door body configured as described above, the latch device is fixed to the door body. Since it is not efficient to connect the operating force transmission cable to both the inside handle device and the latch device due to work space and the like, the latch device and the inside handle are both connected by the operating force transmission cable before the latch. Fixing the device to the door body is performed.

  When the latch device is fixed inside the door body in a state where the latch device and the inside handle device are previously connected by the operation force transmission cable, and the inside handle device is fixed outside the waterproof area by the waterproof sheet, the operation is performed. It is necessary to pull out the force transmission cable and the inside handle device from the service opening to the outside of the panel body, and the operation for closing the service opening with the waterproof sheet needs to be performed in this state.

  On the other hand, an adhesive such as butyl is generally used for the operation of attaching the waterproof sheet, and if the inside handle device connected to the latch device comes into contact with the adhesive before solidification, a dirt defect occurs. It is necessary to prevent the inside handle device from coming into contact with the adhesive, which is a factor of reducing workability.

  As shown in FIG. 1, the manufacture of a vehicle door is performed by remotely operating a latch device 1 and a latch device 1 on a door body 2 in which a preformed outer panel and an inner panel 5 are joined in a bag shape. The inside handle device 4 and the door trim 8 for forming the wall surface in the room, and the outside handle device, window glass, harness, etc., not shown, are arranged.

  In addition, the inner panel 5 of the door body 2 is provided with a service opening 6 that is used for operations such as attachment of components to the inside of the door body 2 and wiring. The service opening 6 is closed by attaching a waterproof sheet 7 after the work using the service opening 6 is completed, and water leakage into the room such as water in the door body 2 is prevented.

  The waterproof sheet 7 is fixed by adhering the waterproof sheet 7 with a butyl rubber-based sealing material or the like applied to the periphery of the waterproof region indicated by a chain line in FIG. 1A (see FIG. 1B).

  In manufacturing the vehicle door, the inside handle device 4 is mounted around the other end of the operating force transmission cable 3 having one end connected to the latch device 1 and then connected to the inside handle device 4. The fixing is performed on the main body 2.

  In this example, the latch device 1 is fixed inside the bag-like door main body 2, and the assembly of the components inside the door main body 2, the wiring, and the like are started on the inner panel 5 of the door main body 2. The service opening 6 is performed. The operating force transmission cable 3 and the inside handle device 4 connected to the latch device 1 are pulled out from the service opening 6 to the surface of the inner panel 5.

  As will be described later, the inside handle device 4 is formed by rotatably holding the operation handle 10 on a base member 17 formed by connecting a handle unit base 15 and a cable unit base 16. The inside handle device 4 pulled out from the service opening 6 is temporarily held on the inner panel 5 using the panel connecting portion 14 formed in the base member 17.

  In this example, the panel connecting portion 14 is formed by fixing the magnet 9 to the handle base. However, the panel connecting portion 14 is formed as a hook-like protrusion formed on the inner panel 5, a hole that can be locked in the hole portion, or a hook-like protrusion. You can also

  The fixing operation of the waterproof sheet 7 is performed by first temporarily holding the inside handle device 4 on the inner panel 5 and then applying a sealing material to the entire periphery corresponding position of the waterproof sheet 7. Thereafter, the waterproof sheet 7 is attached to the opening 6 for the service building from the opposite side edge (left side edge in FIG. 1), and the inside handle device 4 is removed from the temporary holding position with the waterproof sheet 7 attached to the position near the slit 7a. .

The front end of the cable unit is fitted to the cable holding part, and the cable clip piece 16a is inserted into the fitting groove 21a of the end pipe 21 so as to be mounted at a predetermined position on the cable unit base 16. In addition, the inner cable 3b drawn from the outer cable 3a has the guide protrusion 12a of the coupling body 12 fitted in the guide hole 22a so as to be movable. In order to introduce the guide protrusion 12a of the connector 12 into the guide hole 22a, an introduction opening 22b is formed in the guide wall 22.

  As described above, the other end of the operating force transmission cable 3 whose one end is held by the cable unit base 16 is connected to the latch device 1 in advance. In FIG. 10B, the operating force transmission cable 3 corresponding to the operating handle 10 shown in the lower stage is the latch operating portion 1a of the latch device 1, and the operating force transmission cable 3 corresponding to the lock knob 18 shown in the upper stage is the latching apparatus. 1 is connected to each lock operation portion 1b. In this state, the lock operation unit 1b is held in the unlocked state, and when an input to the latch operation unit 1a is given, a latch release operation is performed. When the lock operation unit 1b is shifted to the lock state, the latch operation unit 1b is subsequently operated. The latch release operation by the operation to 1a is prohibited.

  Further, a driving piece 23 a is provided on the side of the connecting body guide recess 23 corresponding to the lock knob 18. As shown in FIGS. 10A and 10B, the drive piece 23 a is provided in a bowl shape so that the end edge is positioned along the central side edge of the coupling body guide recess 23.

  Further, a second locking portion 20 and a first locking portion 24 are provided at the front and rear ends of the cable unit base 16. The second locking portion 20 is formed in a hook shape that extends rearward from the back surface of the front end edge of the cable unit base 16, then extends to the front surface side, and protrudes rearward from the front end. The second locking portion 20 is formed to be elastically deformable. In this example, the elasticity is utilized by forming the cable unit base 16 from a synthetic resin material.

  Further, the first locking portion 24 is formed so as to protrude from the rear end edge portion of the cable unit base 16 to the front surface side, and to protrude forward from the free end thereof. As will be described later, the first locking portion 24 forms a rotation center at the time of the coupling operation to the handle unit 11, and is formed to have an appropriate volume so as not to be easily elastically deformed or broken. The

  The cable unit 13 formed as described above is connected to the handle unit 11 in such a manner that the first locking portion 24 is locked to the rear end edge of the handle unit base 15 from the rear surface side, and then in FIG. This is done by rotating it counterclockwise.

  As described above, when the operation force transmission cable 3 is connected to the latch device 1 in advance, the connection body 12 of the operation force transmission cable 3 connected to the latch operation portion 1a held in the non-input state is not connected to the latch operation portion 1a. In order to correspond to the initial rotation position of the operation handle 10 urged by the torsion spring, the connection body 12 is connected to the connection recess 19 of the operation handle 10 in accordance with the rotation operation of the cable unit 13.
