Japanese Patent Laid-Open No. 2003-221949

  However, in the above-described conventional vehicle door handle device, the harness is guided by the groove-shaped part formed on the handle body side in the state where the electrical components are assembled to the handle body, but it moves to the cover mounting side. It is in a free state. In addition, the groove-shaped portion is only sized so that the harness can be arranged exactly in order to suppress the movement allowance of the harness when the cover is attached. For this reason, when attaching a cover to a handle body, there is a problem that a harness is sandwiched between both members, and in some cases, a disconnection occurs.

  Then, this invention makes it a subject to provide the vehicle door handle device which can be assembled, preventing the disconnection etc. of a harness reliably.

As a means for solving the above problems, the present invention provides:
A vehicle door handle device,
A handle base fixed to the vehicle body,
A handle lever having an arm part rotatably supported by the handle base, a recessed part for storing an electrical component to which a harness is connected, and an insertion part allowing the harness to be pulled out to the outside;
A cover covering the recess of the handle lever;
A vehicle door handle device comprising:
Said handle lever, a guide portion for guiding the harness, provided on the arm portion, has a guide groove for guiding the connected harness electrical components in said recess to said insertion portion,
A harness that is mounted in the guide groove and that is guided to the insertion portion is provided, and a spacer that prevents the harness from falling off from the insertion portion is provided.
The spacer includes a positioning portion that is disposed in the guide portion and that restricts the protrusion of the harness from the handle lever.

With this configuration, the harness can be guided to the insertion portion via the guide groove, and therefore can be assembled with high work efficiency. In addition, before the cover is attached to the handle lever, the harness connected to the electrical component can be held in advance on the handle lever by the spacer. Accordingly, it is possible to prevent in advance a problem that the harness is caught when the cover is attached to the handle lever and the wire breaks. Moreover, the holding state of the harness can be further improved. That is, not only the harness is guided by the guide portion, but also the protrusion of the spacer can be reliably prevented by the positioning portion of the spacer. Therefore, when the cover is attached to the handle lever, it is possible to reliably prevent a problem that the harness is caught.

  It is preferable to further include a handle seat that is attached to the handle lever and includes a holding portion that holds the harness.

  With this configuration, since the harness extending through the insertion portion can be held by the holding portion formed on the handle seat, even when the handle lever is operated, the harness is not displaced, A good mounting state can be maintained over a long period of time.

  According to the present invention, when the electrical component is attached to the handle lever, the harness can be guided to the insertion portion via the guide groove, so that assembly can be performed with good workability. Further, since the harness is held by the spacer, it is possible to prevent a problem that the harness is caught between both members when the cover is attached to the handle lever.

The handle lever 3 and the cover 7 form a handle that is gripped and rotated when the door is opened.

(2. Assembly method)
Next, a method for assembling the vehicle door handle device having the above-described configuration will be described.

  First, the electrical component 6 is mounted on the handle lever 3. That is, the antenna part 41 of the electrical component 6 is arranged in the first recess 20 and the switch part 40 is arranged in the second recess 24. Then, the harnesses 42 a and 42 b bundled by the insulating tube 46 are inserted into the insertion portion 21 through the guide groove 25 formed in the handle lever 3 in a state where the connector 43 is connected. That is, the harnesses 42a and 42b are not inserted into the holes but can be easily arranged in the insertion portion 21 by using the guide grooves 25. For this reason, workability | operativity can be improved. Further, the harnesses 42a and 42b are positioned between the projections 23b and 23c constituting the guide portion 23 and the side walls 23d and 23e, respectively. Since the harness 42a is located on both sides and the harness 42b is located on the inside thereof, the harness 42a can be smoothly arranged between the projections 23b, 23c and the side walls 23d, 23e, and the harness 42b can be smoothly arranged between the projections 23a, 23b, 23c. it can. As described above, since the harnesses 42a and 42b are configured to be inserted into the insertion portion 21 via the guide groove 25, the connector 42 is fixed to the end portions of the harnesses 42a and 42b. The harnesses 42a and 42b can be inserted into the insertion portion 21 regardless of the size. Therefore, since it is not necessary to make the size of the insertion part 21 larger than that of the connector 43, the appearance is good and the strength of the handle lever 3 is not lowered.

  Subsequently, the spacer 5 is press-fitted into the guide groove 25 of the handle lever 3. Then, it can be seen that when the locking claw 5a of the spacer 5 is locked to the locking receiving portion 29b of the handle lever 3, a click feeling is obtained and the spacer 5 is attached at an appropriate position. In this state, the first positioning portion 37 is positioned in the positioning groove 28 of the handle lever 3, the second positioning portion 38 is positioned in the positioning recess 22, and the third positioning portion 39 is positioned in the guide portion 23. Thereby, the guide groove 25 is occupied by the spacer 5, the insertion part 21 becomes a hole shape, and the harnesses 42a and 42b (insulating tube 46) are guided. Further, the third positioning portion 39 of the spacer 5 does not protrude from the handle lever 3 from the insulating tubes 46 of the harnesses 42 a and 42 b inserted through the insertion portion 21 and the harnesses 42 a and 42 b of the guide portion 23. Regulate the position.

  Next, the cover 7 is attached to the handle lever 3. The cover 7 is attached by positioning the positioning projection 17 e at one end of the handle lever 3 in a recess (not shown) formed at the inner end of the cover 7 and then positioning the cover 7 on the upper surface of the handle body 17. Then, the screw is screwed from the inside through the through holes 17a and 17c formed in the handle lever 3. In the through-hole 17a, a screw can be screwed into the cover 7 while avoiding interference in spite of being a region where the electrical component 6 is disposed by the U-shaped portion 45 formed on one end side of the antenna portion 41. It is possible. The cover 7 can be fixed to the handle lever 3 in a well-balanced manner by screwing these three locations. At this time, the positions of the harnesses 42 a and 42 b are already regulated by the spacer 5 without protruding from the handle lever 3. Therefore, when the cover 7 is attached, there is no problem of disconnection between the cover 7 and the handle lever 3. In addition, one side of the double-sided tape 48 is attached in advance to the inner surface of the cover 7, and when the cover 7 is attached, the remaining one side is attached to the surface of the electrical component 6. Thereby, the storage state of the antenna part 41 can be stabilized, and it becomes possible to prevent backlash and position shift reliably. In the state where the cover 7 is attached, the pressing portion of the switch portion 40 is exposed from the switch opening 47, and when the handle is rotated, the pressing operation can be performed with the thumb.

  Thereafter, the handle seat 4 is attached to the handle lever 3. The handle seat 4 is fixed by hooking the connecting portion 32a of the handle seat 4 to the hook-shaped portion 29a of the handle lever 3, and then the shaft portion 27 formed on the arm portion 18 of the handle lever 3 on the bearing portions 33a and 33b. This is done by locking the shaft portion 17d protruding from the inner surface of the lever 3. At this time, the harnesses 42 a and 42 b and the connector 43 bundled by the insulating tube 46 are pulled out from between the side wall portions 32 and inserted between the holding portions 35 to be held. Thereby, a part of the arm portion 18 of the handle lever 3 enters the escape hole 34, and the harnesses 42 a and 42 b are held between the holding portion 35. As a result, the position of the harnesses 42a and 42b can be prevented from shifting during the operation described later, and a good mounting state can be provided over a long period of time.

  Finally, these are mounted on the handle base 2 provided on the door panel 1. In mounting on the handle base 2, the handle base 2 is screwed to the fixing member 11 or the nut 16. Then, the end cover 10 is attached to the handle base 2, and the bearing portion 26 formed on the arm portion 18 of the handle base 2 is rotatably supported on the support shaft 15.

(3. Operation)
Next, the operation of the vehicle door handle device will be described.

  When the operator carries the wireless device (electronic key) and approaches the vehicle, this is detected by the antenna unit 41 and is referred to the identification data stored in the storage unit in advance by a control unit (not shown). When it is determined that the electronic key is appropriate and the switch unit 40 is pushed, a door lock device (not shown) is driven to bring the door into an unlocked state. Accordingly, when the handle is pulled and rotated around the support shaft 15, the lever 30 is rotated through the contact piece 31, and the latch mechanism (not shown) is driven to open the door. When the handle is rotated, the harness 42 is positioned between the guide portion 23 and the third positioning portion 39 of the spacer 5 via the insulating tube 46, and the movement from the insertion portion 21 is restricted, and the handle seat 4 Between the holding portion 35 and the arm portion 18 of the handle lever 3. Therefore, the harnesses 42a and 42b are not displaced, and a good mounting state can be maintained for a long time.
