Description

  The present invention relates to a door handle device used for a vehicle or the like.

  In recent years, a so-called keyless entry function capable of locking and unlocking a door latch without performing a key operation is mounted on a vehicle. In keyless entry, for example, when the operator carries a wireless device (electronic key), the door latch can be locked and unlocked simply by approaching or leaving the vehicle, or by operating a door handle switch, etc. Can do.

  In a vehicle door handle device employing this keyless entry, a switch, an antenna, and the like are arranged in the handle body. For example, in Patent Document 1, a handle body is divided into a plurality of parts, and a switch, an antenna, and the like are arranged. In addition, wiring for switches, antennas, and the like has been drawn into the door through the hinge side of the handle body.

  In addition, a technique is disclosed in which a switch, an antenna, and the like are arranged in a hollow outer handle body, and a cap is used to close the hollowed die-cut opening (see Patent Document 2).

  Furthermore, a technique is disclosed in which an arm portion that engages with a handle lever for operating the door latch device is configured as a separate part, and this is inserted into a hollow portion of the handle body and fixed (see Patent Document 3).

  However, the configuration of Patent Document 1 has a problem that the number of parts of the handle main body increases. In addition, the assembly is not good due to the complicated structure.

  Moreover, even if it was the structure of patent document 2, since an antenna, a switch, and a cap were assembled separately, respectively, the assemblability was bad. In addition, it is necessary to either form the connector provided at the tip of the wiring in a size that can pass through the hollow portion or to assemble the connector after the wiring passes through the hollow portion. If the connector is downsized, the subsequent assembling property may be deteriorated or the reliability may be reduced. Further, if the hollow portion is widened, the handle body is enlarged. In addition, when the connector is assembled later, the assemblability deteriorates.

  Furthermore, when the handle arm portion is configured as a separate part as in Patent Document 3 and inserted into the hollow portion of the handle body, there is a problem that a space for arranging a switch, an antenna, and the like becomes narrow.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a perspective view showing a first embodiment of a door handle device 1 according to the present invention.
FIG. 2 is a cross-sectional view of the door handle device 1 taken along the arrow AA shown in FIG.
Note that each of the following drawings including FIG. 1 and FIG. 2 is a diagram schematically shown, and the size and shape of each part are appropriately exaggerated for easy understanding.
In the following description, specific numerical values, shapes, materials, and the like are shown and described, but these can be changed as appropriate.

  The door handle device 1 of the present embodiment is a handle that is attached to a base 30 provided on a door of a vehicle and that is operated when the door is opened and closed, and includes a handle body 10 and an operation switch 20. Further, the door handle device 1 of the present embodiment is a so-called keyless device that can lock and unlock the door latch without operating the key if the operator carries the wireless device (electronic key). It is used for a vehicle having a function called entry.

The handle body 10 is formed in a bar shape that is slightly curved as a whole so that the operator can easily hold and operate the handle body 10.
The handle body 10 has a hinge portion 11 at one end.
The hinge portion 11 is formed in a substantially L-hour shape bent from the back surface side (lower side in FIG. 2) of the handle body 10 toward the outer side direction (right side in FIG. 2, for example, the front side of the vehicle). Yes. In the following description, the upper side in FIG. 2 is called the front side, and the lower side in FIG. 2 is called the back side.

  A bearing portion 11 a formed in a substantially U shape is provided at the distal end portion of the hinge portion 11. The bearing portion 11 a is rotatably engaged with the shaft support portion 31 of the base 30. The handle body 10 can be rotated about the shaft support portion 31 as a rotation center.

FIG. 3 is a perspective view showing only the handle body 10.
The handle body 10 has an opening 13 at the end (arm side) opposite to the end where the hinge 11 is provided. In the following description, the side on which the hinge portion 11 is provided (the right side in FIG. 2) is referred to as the hinge side, and the side on which the arm portion 12 described later is provided (the left side in FIG. 2) is the arm. We will call it the side.

  The handle main body 10 is formed with an accommodating portion 14 that is a cylindrical space continuing from the opening 13. The accommodating portion 14 is a space for accommodating an antenna 23 described later. The accommodating portion 14 is formed in a curved shape that substantially follows the outer shape of the handle body 10. The handle main body 10 of the present embodiment is formed by resin molding, and the accommodating portion 14 is formed by die cutting while the mold moves along a curved shape. The die cutting method as described above is more complicated than a normal simple die splitting method. However, by forming the accommodating portion 14 in a curved shape, the strength of the handle body 10 can be ensured without unnecessarily increasing the size of the handle body 10 even if a sufficient space is secured in the accommodating portion 14.

  Note that the handle body 10 of the present embodiment accommodates the antenna 23 in the accommodating portion 14 thereof. Therefore, since the handle body 10 needs to be formed so that electromagnetic waves can pass therethrough, it is a resin molded product. However, the resin is not limited to resin as long as electromagnetic waves can pass and strength can be secured.

On the front side of the end of the arm of the handle body 10, a button groove 13 a formed in a U shape is formed as a part of the opening 13.
Further, on the back side of the end portion of the handle body 10 on the arm side, an arm portion 12 protruding to the back side and extending is formed. At the tip of the arm portion 12, a contact piece 12a is formed to protrude in a shape bent toward the hinge side. The contact piece 12a is engaged with a handle lever 32 that operates a door latch device (not shown). When the operator grips the handle body 10 and pulls it to the front side, the handle body 10 rotates. As a result, the contact piece 12a moves the handle lever 32, operates the door latch device to release (unlatching) the door, and the door can be opened and closed.

Further, the arm portion 12 is formed with a groove portion 12 b that is connected from the accommodating portion 14 to the back side end portion of the arm portion 12. A wiring 27 described later is accommodated in the groove 12b.
Further, an engagement hole 12 c is formed in the contact piece 12 a of the arm portion 12. The engaging claw 25 of the operation switch 20 engages with the engaging hole 12c. In addition, although the engagement hole 12c of this embodiment is formed so as to penetrate the contact piece 12a, it does not need to penetrate, and is provided in another part according to the position of the engagement claw 25. It may be done.

The operation switch 20 is attached to the opening 13 so as to close the opening 13.
FIG. 4 is a perspective view showing only the operation switch 20.
The operation switch 20 includes a lid portion 21, a button portion 22, an antenna 23, a cover portion 24, an engagement claw 25, a communication hole 26, a wiring 27, and a connector 28.

  The lid 21 is formed in a shape that covers the opening 13 of the handle body 10. The lid portion 21 has a protruding portion 21 a that is inserted into the accommodating portion 14. A button portion 22 and an antenna 23 are fixed to the protruding portion 21a. Further, a screw 40 is screwed into the protruding portion 21a through the handle body 10 from the back side, and the operation switch 20 is fixed to the handle body 10.

  The button part 22 constitutes a main part as a switch of the operation switch 20, and is attached to the protruding part 21a. The button part 22 includes a push button switch inside, and the outside is covered with an exterior such as rubber. The button part 22 is adapted to fit into the button groove 13 a of the opening part 13.

  The antenna 23 is used for communication with a wireless device carried by the operator, and is attached to the protruding portion 21 a on the hinge side with respect to the button portion 22.

FIG. 5 is an enlarged cross-sectional view of the vicinity of the arm side in FIG.
The cover part 24 is formed so as to cover the groove part 12b of the handle body 10 from the arm side. The cover 24 is preferably formed of a resin having high slidability such as nylon 12 which is a polyamide-based resin. This is so that when the door handle device 1 rotates, even if the cover 24 comes into contact with the arm-side structure 33 of the base 30 due to deformation or distortion of the vehicle body or the like, the operation is not hindered. It is. A predetermined gap is secured between the cover portion 24 and the arm-side structure 33 so that the door handle device 1 does not come into contact when rotating.

  The engagement claw 25 is an engagement portion that engages with the engagement hole 12 c of the arm portion 12. The cover portion 24 is fixed to the arm portion 12 by the engagement between the engagement claw 25 and the engagement hole 12c. Note that the cover portion 24 may be fixed using screws or the like.

  The communication hole 26 is a communication part formed so as to penetrate in the front and back direction in the region between the cover part 24 and the engaging claw 25. The communication hole 26 communicates with the groove 12b, and the wiring 27 can be inserted therethrough. In the present embodiment, the communication hole 26 has a hole shape, but may be formed as a notch-shaped communication portion that is partially open. Further, for example, the communication hole 26 may be opened in the cover portion 24 so that the wiring 27 is drawn out to the arm side.

  The wiring 27 is a harness in which a plurality of conductors that electrically connect the button portion 22 and the antenna 23 are bundled. The wiring 27 extends into the groove 12b and is led out from the communication hole 26 to the back side. Since the wiring 27 passes through the groove portion 12b and is drawn out from the communication hole 26 to the back side, and the cover portion 24 is further provided, the wiring 27 can be easily handled when assembled. Further, the door handle device 1 can be assembled with the connector 28 attached to the wiring 27. Furthermore, the wiring 27 is reliably held in the groove 12b, and an accident that the wiring 27 is caught during the operation of the door handle device 1 can be prevented.

  The connector 28 is attached to the tip of the wiring 27 and is connected to a vehicle body side connector (not shown).

In the present embodiment, at least a part of the button portion 22 and the antenna 23 is insert-molded and integrated when the lid portion 21 is molded. Then, the wiring 27 to which the connector 28 is previously attached is connected, and an exterior such as rubber covering the button portion 22 is attached, and the unit of the operation switch 20 is completed.
In addition, the button part 22 and the antenna 23 may be prepared as separate parts for the lid part 21 and assembled as a unit of the operation switch 20 using screws or the like.

First, as described above, the operation switch 20 is assembled as a unit. Next, the tip of the antenna 23 is inserted from the opening 13 of the handle body 10 and the opening 13 is closed by the operation switch 20. Further, the engaging claw 25 is engaged with the engaging hole 12c. Further, the screw 40 is tightened to fix the handle body 10 and the operation switch 20. Thus, the assembly work of the door handle device 1 can be completed with a very simple work.

FIG. 7 is a perspective view showing a state after the door handle device 1 is assembled.
By simply inserting the operation switch 20 and tightening the screws, the button portion 22 and the antenna 23 are attached to the handle body 10 and the door handle device 1 is completed.

As described above, according to the present embodiment, the operation switch 20 holds the antenna 23. And the antenna 23 is accommodated in the cylindrical accommodating part 14, and the opening part 13 is obstruct | occluded by the operation switch 20. FIG. As for the operation switch 20, the button part 22, the antenna 23, the wiring 27, and the connector 28 are assembled as one unit beforehand. The operation switch 20 also has a lid function for closing the opening 13. Therefore, the assembling work of the door handle device 1 is only a very simple work as shown in FIG. Furthermore, neither the operation switch 20 nor the handle main body 10 has a simple configuration, requiring no special parts or the like as compared with the conventional one. Therefore, the door handle device 1 has a small number of parts, has a simple structure, and is easy to assemble.
Further, since the handle body 10 is formed in a cylindrical shape, the door handle device 1 has the same cross-sectional shape, so that the strength is increased compared to the form divided into two parts, and the joint of the two parts There is no deterioration in tactile sensation during operation.
Furthermore, since the hinge part 11 and the arm part 12 are integrally molded with the handle body 10, the door handle device 1 has all the precision, strength, reliability, assemblage, and cost as compared with the conventional form divided into a plurality of parts. Is excellent in terms of

(Deformation)
The present invention is not limited to the embodiment described above, and various modifications and changes are possible, and these are also within the scope of the present invention.

(1) In the present embodiment, the antenna 23 has a simple rectangular parallelepiped shape, and has been described with an example in which the antenna 23 is inserted as it is into the housing portion 14. For example, a restricting unit that restricts the position of the antenna in the housing portion may be provided. For example, a sponge-like or spring-like elastic member may be provided on one surface of the antenna. This elastic member may be configured as a separate part or formed integrally with the antenna.
FIG. 8 is a view showing a modification in which an urging portion 230 a as a restricting means is provided on one surface of the antenna 230.
On the back side of the antenna 230, three protruding urging portions 230a are formed integrally with the antenna 230. The urging portion 230a is made of an elastically deformable resin. When the antenna 230 is inserted into the housing portion 14 as shown in FIG. 8, the biasing portion 230a is elastically deformed to bias the antenna 230 to the front side. As a result, the antenna 230 is moved toward the front side in the accommodating portion 14 and the position thereof is restricted, so that the antenna 230 does not rattle. In addition, since the antenna 230 is moved to the front side in the housing portion 14, the communication characteristics are improved. In FIG. 8, the antenna 230 is shown to maintain a linear shape. However, for example, the antenna 230 itself may be deformed along the wall shape on the front side of the housing portion 14. Further, by shaping the antenna shape into a shape along the wall surface shape, the gap with the handle can be kept constant, and the load may be applied uniformly to the urging portion.

(2) In the present embodiment, the operation switch 20 has been described as having a cover portion 24. For example, the portion corresponding to the cover portion may be omitted as a form in which the wiring is exposed to the tip of the arm portion by insert molding in the arm portion.

(3) In this embodiment, the button part 22 demonstrated and demonstrated the example which is a pushbutton switch. For example, a touch sensor may be provided instead of the button unit 22.

(4) In the present embodiment, the door handle device 1 has been described with a mode in which an operator opens the door by gripping the handle body 10 and pulling it to the front side. For example, the present invention may be applied to a door handle device in which a rotation shaft extending in the front and back direction is provided on the hinge side and the handle main body is rotated about the rotation shaft.

(5) In the present embodiment, an example in which the engaging claw 25 is fitted from below the engaging hole 12c has been described. For example, the cover portion 24 may be extended so that the engagement claw 25 is wound around and the engagement claw 25 may be fitted from above the engagement hole 12c.
FIG. 9 is a diagram showing a state before the engaging claw 25 is fitted into the engaging hole 12c in the modified embodiment.
The engaging claw 25 is provided at the tip of an extension part 24 a obtained by extending the cover part 24. Here, the extension part 24a is formed of nylon 12 which is a polyamide-based resin, for example. Since nylon 12 has good bending resistance (hinge), the extension 24a can be easily bent as shown by the arrows in the figure.
FIG. 10 is a view showing a state in which the extension 24a is bent and the engagement claw 25 is fitted into the engagement hole 12c from above.
When the engaging claw is fitted into the engaging hole 12c from above in the form shown in FIG. 10, the contact portion with the handle lever 32 becomes nylon 12. Thereby, the slidability with the handle lever 32 becomes good, and the operation feeling can be improved.

  In addition, although embodiment and a deformation | transformation form can also be used in combination as appropriate, detailed description is abbreviate | omitted. Further, the present invention is not limited by the embodiments described above.
