Description

  The present invention relates to a vehicle door handle (hereinafter referred to as “door handle”) that is attached to a door of a vehicle (for example, an automobile) and is caused when the door is opened.

  Various types of door handle devices are attached to the door portion of the vehicle in order to open the door. For example, there is a configuration in which the door lock mechanism is released when the handle main body of the handle is gripped and raised to the near side, and the door is opened by raising the handle as it is. As this type of door handle device, there is one disclosed in Patent Document 1.

  Recently, in a vehicle, the user who has the portable key has approached the vehicle by performing wireless communication between the portable key possessed by the user of the vehicle and the antenna (entered in the authentication area). A system is known that automatically unlocks (unlocks) the door by detecting the door, and automatically locks (locks) the door by detecting that the user has left the vehicle. (See Patent Document 2). In many cases, this antenna is installed in a door handle constituting the door handle device in consideration of convenience for the user.

  As shown in FIG. 9, a conventional door handle 50 includes a handle main body 51 gripped by a user, a base body 52 fitted into the bottom surface of the handle main body 51, and a user's portable key (not shown). Are provided with an antenna 53 for transmitting radio waves of a predetermined frequency, and a lock / unlock switch 54 (push button switch) for locking the door after the user gets off the vehicle. An arm portion 55 serving as a rotation fulcrum when the handle main body 51 is raised is provided at one end portion in the longitudinal direction of the handle main body 51, and a guide portion 56 for guiding an operation for causing the handle main body is provided at the other end portion. Is provided.

A conventional door handle 50 is integrated with a handle body 51 by attaching an antenna 53 to a base body 52. For this reason, the process of assembling the antenna 53 to the base member 52 is required. Moreover, since the door handle 50 is frequently operated, a certain strength is required. However, since the recess (not shown) for fitting the base body 52 into the handle body 51 must be formed, the strength of the handle body 51 is lowered. Further, in order to prevent the antenna 53 from being damaged or displaced by an external force when the handle main body 51 is raised, it is necessary to push a buffer material into the antenna fitting portion 57 of the base member 52 or use an adhesive. There is more and more time and effort to assemble it.

  In view of the above-described problems, an object of the present invention is to reduce the trouble of incorporating an antenna into a vehicle door handle and to improve the durability of the vehicle door handle.

Means and effects for solving the problems

The present invention for solving the above problems is as follows.
A door handle for a vehicle caused by a user when opening the door from the outside of the vehicle,
An elongated grip that is gripped by the user when raised, and
An arm portion that protrudes from one end portion in the longitudinal direction on one surface side in the thickness direction of the grip portion and serves as a rotation fulcrum when raised;
A projecting portion that also projects from the other end and guides its movement when raised,
It is assumed that an antenna for transmitting or receiving radio waves is insert-injected and molded in the grip portion.

In the above-described premise configuration of the vehicle door handle according to the present invention, the antenna is insert injection molded in the grip portion. For this reason, the grip portion and the antenna are already integrated, the number of parts is reduced, and the trouble of assembling the antenna to the grip portion becomes unnecessary. In addition, it is not necessary to form a recess for retrofitting the antenna to the grip portion, and the antenna is disposed in the grip portion without any gap, so that the strength of the grip portion is increased and the load on the antenna is reduced. . This improves the durability and reliability of the door handle.

And the said antenna is arrange | positioned in the approximate center part at a fixed distance from the outer periphery of the said grip part in sectional view . More thereto, the external force acting on the grip portion can be suppressed to cover the antenna. Thereby, durability and reliability of the door handle are further improved. Further, by making the member used for the grip portion high in strength (tensile strength), the load on the antenna can be further reduced. The antenna has an elongated shape, and the grip portion is provided with openings for projecting both ends in the longitudinal direction of the antenna so that one end portion of the antenna is the one end portion. And a cable connected to the cable, and projecting from the inside of the grip part to the outside through the opening.

  Moreover, you may equip the said grip part with the cover body which coat | covers the other surface side (The side which is not provided with an arm part or a guide part and is visually recognized by the user) in the thickness direction.

  Preparing cover bodies of various surface treatments (for example, painting and plating) and various forms (for example, resin-molded resin molded products and film insert molded products on which radio wave permeable metal is deposited) in advance and replacing them Thus, the design of the door handle can be easily changed. At this time, since the grip portion of the door handle can be shared, even if the design can be changed, it is not necessary to increase the cost of the door handle.

  And in the door handle for vehicles which concerns on this invention, the required intensity | strength as a door handle is ensured only by one component of the said grip part. That is, unlike a conventional vehicle door handle, a separate member (for example, a base member to which an antenna is attached) is not attached to the grip portion. Up.

  Examples of the present invention will be described. 1 is a front view of a door handle device 100 in which a door handle 110 according to an embodiment of the present invention is used, FIG. 2 is a front sectional view of the door handle 110, FIG. 3 is a perspective view in an exploded state, and FIG. FIG. 5 is a sectional view taken along line XX in FIG.

  As shown in FIG. 1, a door handle device 100 is attached to a portion of the door D of the vehicle. The door handle device 100 according to this embodiment includes a door handle 110 and a base member 120. The door handle 110 is rotatable about a rotation fulcrum P in a state where it is assembled to the base member 120, and is raised in the direction Q with respect to the base member 120. In FIG. 1, the door handle 110 in the raised state is indicated by a two-dot chain line.

  First, the door handle 110 will be described. As shown in FIGS. 1 and 2, the door handle 110 of this embodiment includes a handle body 1 and a cover body 2 that covers the surface side of the handle body 1. The handle body 1 includes a long grip portion 3 formed from a single or plural types of resin materials such as polycarbonate resin, polybutylene terephthalate resin, nylon resin, and the back surface side (thickness direction) of the grip portion 3. An arm that protrudes from one end in the longitudinal direction B (on the side close to the door D) on the one surface side of A (left side in the drawing view of FIG. 1) and serves as a pivotal fulcrum when the door handle 110 is raised A portion 4 and a guide portion 5 that projects from the other end (right side in the drawing view of FIG. 1) and guides the movement of the door handle 110 when it is raised. The grip portion 3 of the door handle 110 has a smooth curved surface as a whole so that the feel when gripped is good. When the handle body 1 is assembled to the base member 120, the handle body 1 is rotated in an arc shape around the rotation fulcrum P formed at the front end portion of the arm portion 4.

  As shown in FIGS. 2 to 4, the front side (the arm part 4 side) in the longitudinal direction B of the grip part 3 of the handle body 1 of this embodiment communicates the front side and the back side of the grip part 3. A front opening 6 is provided. Further, a rear opening 7 that opens to the front surface side of the grip portion 3 and is closed on the back surface side is provided at the rear portion (the guide portion 5 side) of the grip portion 3 in the longitudinal direction B. A rear side of the rear opening 7 is cut out to dispose a lock / unlock switch 8, and a switch mounting portion 9 is provided. When the user holding the portable key operates (presses) the lock / unlock switch 8, the door D of the vehicle can be locked or unlocked.

  An antenna 11 is built in the grip portion 3. The antenna 11 has, for example, a ferrite 12 housed in an elongated cylindrical case body 13 and has a function of transmitting radio waves of a predetermined frequency to a portable key possessed by the user. A cable 15 extends from the front end portion of the case body 13. A connector 16 is attached to the tip of the cable 15. The connector 16 is attached to the cable 15 after the handle body 1 is injection molded.

  A front end portion in the longitudinal direction of the antenna 11 (same as the longitudinal direction B of the grip portion 3) protrudes from the grip portion 3 and is disposed in the front opening 6. Thereby, the cable 15 and the connector 16 of the antenna 11 can be pulled out of the grip portion 3.

  As shown in FIG. 5, the case body 13 that accommodates the ferrite 12 in the antenna 11 is disposed at substantially the center in the thickness direction A and the width direction C in the cross-sectional view of the grip portion 3. In other words, the distance L1 in the thickness direction A from the surface of the grip portion 3 to the case body 13 is substantially equal to the distance L2 in the thickness direction A from the back surface of the grip portion 3 to the case body 13. A distance L3 in the width direction C from the left side surface of the grip portion 3 to the case body 13 is substantially equal to a distance L4 in the width direction C from the right side surface of the grip portion 3 to the case body 13. When the door D of the vehicle can be opened, a large force (bending force, twisting force, etc.) acts on the grip portion 3 of the handle body 1. This may damage the antenna 11. However, in the case of the door handle 110 of the present embodiment, the antenna 11 is disposed at substantially the center of the grip portion 3 in a cross-sectional view. Thereby, when the handle body 1 is raised, the external force acting on the antenna 11 can be minimized, so that the antenna 11 is hardly damaged.

  Further, at both ends of the grip portion 3 in the width direction C, two groove portions 17 opened on the surface side are provided so as to communicate the front side opening 6 and the rear side opening 7. Two cables 18 extending from the lock / unlock switch 8 are arranged in each groove portion 17, and their leading ends are drawn out of the grip portion 3 from the front opening 6.

  As shown in FIGS. 2 to 4, the entire surface side of the grip portion 3 is covered with the cover body 2. The cover body 2 is made of a thin resin material and is attached to the grip portion 3 with a sense of moderation. An insertion hole 19 through which the lock / unlock switch 8 is inserted is provided in a portion of the cover body 2 corresponding to the switch mounting portion 9 of the grip portion 3. When the cover body 2 is fitted into the grip portion 3 of the handle body 1, the distal end portion of the lock / unlock switch 8 passes through the insertion hole 19 and slightly protrudes outside the cover body 2. As a result, the user can operate the lock / unlock switch 8. Further, since the lock / unlock switch 8 is sandwiched between the cover body 2 and the grip portion 3, there is no possibility that the lock / unlock switch 8 is detached from the handle body 1. Furthermore, each groove part 17 is hidden by the cover body 2, and cannot be visually recognized from the outside.

  Since the cover body 2 covers the entire grip portion 3, the design of the door handle 110 can be made different by making the cover body 2 replaceable. For example, by preparing in advance a cover body 2 that is colored in each color and a cover body 2 that is decorated with materials, plating, or the like, the door according to the color of the vehicle while keeping the grip portion 3 in common. The design of the handle 110 can be easily changed. In addition, by changing the outer surface shape while keeping the inner surface shape of the cover body 2 the same (for example, attaching a decorative member such as an emblem), the door handle can be used according to the grade of the vehicle while keeping the grip portion 3 in common. It is easy to change 110 designs.

  Next, the base member 120 will be described. As shown in FIG. 1, the base member 120 has an arcuate shape, and has a door handle 110 at one end (left side in the drawing view of FIG. 1) in the longitudinal direction (equal to the longitudinal direction B of the door handle 110). A pivot fulcrum part 21 for connecting the arm part 4 is provided. Similarly, a rotation guide portion 22 for connecting the guide arm portion 5 of the door handle 110 is provided at the other end portion.

  Next, an operation when the handle body 1 of the door handle 110 of this embodiment is molded will be described. As shown in FIG. 6, the molding die S for molding the handle main body 1 includes a movable die 23 and a fixed die 24. The antenna 11 is inserted into the movable mold 23 in the mold open state. A slide core 25 is attached to the movable mold 23, and the slide core 25 grips an end portion of the antenna 11 on the side where the cable 15 is not provided. Further, the movable mold 23 has convex portions 26 that support the antenna 11 protruding in two places. Thereby, the antenna 11 is arranged away from the cavity surface 23a of the movable mold 23 by a certain distance L1 (see FIG. 5). Further, the cable 15 of the antenna 11 is accommodated in a recess 27 provided in the movable mold 23. Thereby, there is no possibility that the cable 15 of the antenna 11 may be damaged.

  As shown in FIG. 7, the movable mold 23 moves (advances) in the direction of the arrow 28, and the mold S is closed. In this state, the antenna 11 is disposed away from the cavity surface 24a of the fixed mold 24 by a distance L2 (see FIG. 5). Then, the molten resin 29 is injected into the cavity of the mold S (between the cavity surface 23a of the movable mold 23 and the cavity surface 24a of the fixed mold 24). The cable 15 of the antenna 11 is disposed in the concave portion 27 of the movable mold 23 formed in a sealed state, and does not come into contact with the molten resin 29.

  As shown in FIG. 8, after the predetermined time has elapsed and the molten resin 29 has solidified, the movable mold 23 is retracted, and the mold S is opened. At this time, since the slide core 25 moves in the direction of the arrow 31 by a mechanism (not shown), the slide core 25 is detached from the end of the antenna 11. At the same time, the protruding pin 32 built in the movable mold 23 moves forward to protrude the molded handle body 1. Thereby, the handle body 1 is discharged.

  The operation of the door handle 110 of this embodiment will be described. When a user having a portable key enters the authentication area and presses the lock / unlock switch 8 of the door handle 110, each door D of the vehicle is unlocked. For this reason, the user can open the door D only by raising the grip part 3 of the handle body 1 to the near side as it is. When the user closes the door from the outside of the vehicle, when the door D is pushed back and the lock / unlock switch 8 of the door handle 110 is operated (pressed), each door D of the vehicle is locked.

  As described above, the handle body 51 of the conventional door handle 50 is provided with a recess for mounting the base body 52, so that the strength is low, and the antenna 53 can be attached by using the door handle 50 for a long period of time. There is a risk of damage. On the other hand, in the door handle 110 of the present embodiment, since the antenna 11 is insert-molded integrally with the grip portion 3, almost no gap is formed between the antenna 11 and the grip portion 3. As a result, compared with the case where the antenna 11 is not installed, the strength of the grip portion 3 hardly decreases. Further, since the handle main body 1 and the antenna 11 are integrated, the number of parts is reduced, and the labor required for assembling the door handle 110 can be reduced.

  And the design of the door handle 110 can be easily changed by exchanging the cover body 2.
