Description

  The present invention relates to a vehicle door handle device.

  In recent years, an increasing number of vehicles such as automobiles are equipped with a keyless entry system for the purpose of improving convenience and security. The keyless entry system uses a wireless key between a portable key held by the driver and an in-vehicle device including a wireless communication device to collate password data, etc. This is a system that operates without key operation.

  In this keyless entry system, the door handle that is assembled to the opening of the door outer panel of the vehicle and serves as a grip when the door is opened and closed is made into a hollow structure. Some have built-in peripheral circuits. However, when an antenna is incorporated in the door handle, if the door handle bends due to a load when the door handle is operated, the antenna fixed to the door handle may be deformed to deteriorate its performance.

  Therefore, an electrical component housed in the internal space formed in the door handle with a gap between the inner wall surface of the door handle and an elastic member fixed to the electrical component and crimped to the inner wall surface of the door handle The elastic member absorbs the bending even when the door handle is bent due to a load during operation of the door handle, and the electric member swings in the range of the gap between the inner wall of the door handle. A vehicle door handle device that supports parts has been devised (see Patent Document 1).

JP 2004-324106 A

  In the configuration of Patent Document 1, when the door handle is bent or shocked more than expected at the time of design, the electrical component (antenna) may be deformed to lower the electrical performance. Further, when the door handle is made thinner, the gap becomes narrower, and it becomes difficult for the elastic member to support the electric component so that the electric component swings in the range of the gap between the inner wall surface of the door handle.

  Furthermore, there is a problem in that an electric component having no flexibility cannot be accommodated in the door handle.

  Against the background of the above problems, an object of the present invention is a vehicle capable of suppressing a deterioration in performance of an electrical component without being affected by a gap between the electrical component housed inside the door handle and the inner wall surface of the door handle. It is to provide a door handle device.

Means for Solving the Problems and Effects of the Invention

A vehicle door handle device for solving the above-described problems is a door handle device for a vehicle including a handle body and a handle cover attached so as to cover the handle body. The door is formed by the handle body and the handle cover. An electric component that is an antenna unit including at least an antenna element housed in an internal space of the handle device, a surface that is fixed to the electric component and faces the electric component on the inner wall surface of the handle body, and an electric power on the inner wall surface of the handle cover It is premised that the surface facing the component and a buffer member that fills a gap formed by the electrical component are filled so as to be crimped to the inner wall surface of the door handle.

  With the above configuration, when the door handle is subjected to a deflection or impact that is greater than expected at the time of design, deformation of the electrical component can be suppressed to prevent a decrease in electrical performance of the electrical component. Moreover, even if the door handle is thinned and the gap is narrowed, the electrical component can be protected by the elastic member. Moreover, the electrical component which does not have flexibility can also be accommodated in a door handle. Furthermore, in Patent Document 1, the size and mounting position of the elastic member must be taken into account according to the electrical component to be accommodated. In the configuration of the present invention, the buffer member is filled between the electrical component and the inner wall surface. Therefore, it is possible to save the trouble of these considerations.

  Moreover, the buffer member in the vehicle door handle device of the present invention is a member having an elastic force, and is crimped to the inner wall surface of the door handle by the elastic force.

  The members having elastic force include various materials including rubber materials, and are widely used in various fields. With the above configuration, the cushioning member can be configured with a member that is easily available and low-cost.

  Further, the buffer member in the vehicle door handle device of the present invention is a sheet-like member, and is wound around and fixed to the surface of the electrical component.

  With the above configuration, the buffer member can be formed at low cost without complicated processing.

  Further, the electrical component in the vehicle door handle device of the present invention is provided in the vehicle, and is preliminarily stored in the vehicle based on the communication result between the mobile key possessed by the user and a communication unit that performs predetermined communication with the mobile key. The antenna of the communication part in a keyless entry system provided with the vehicle-mounted apparatus containing the operation | movement permission part which permits defined operation | movement is included.

  In the keyless entry system, for example, it is desirable to control the unlocking / locking for each door. From the security aspect, the reach of the radio wave transmitted to the portable key is set near the door (or door handle) (the radio wave far away). To avoid flying). With the above configuration, it is possible to ensure the security of the keyless entry system without impairing the convenience of the unlocking / locking operation of the door.

  Hereinafter, a vehicle door handle device of the present invention will be described with reference to the drawings. FIG. 1 shows an exploded perspective view of a vehicle door handle device (hereinafter abbreviated as “door handle”) 1 of the present invention. The door handle 1 includes a handle body 51 and a handle cover 11 that is attached so as to cover the handle body 51 and forms a design surface outside the vehicle body. The buffer member 21 and the antenna unit (electrical component of the present invention) 31 are accommodated in an antenna unit accommodating portion 54 that is an internal space of the door handle 1 and is formed by the handle main body 51 and the handle cover 11. Moreover, the door switch 41 is accommodated in the door switch accommodating part 55 which is the same internal space.

  The handle cover 11 is provided with an opening 12 for attaching the door switch 41 so as to be exposed to the outside.

  The buffer member 21 is composed of a rubber material such as ethylene-propylene-diene rubber, an elastic resin such as vinyl or silicon, an elastic member such as sponge or urethane foam, and the inner wall surface of the antenna unit housing portion 54 by its elastic force. Crimped to. In the example of FIG. 1, the buffer member 21 is formed in a cylindrical shape (details will be described later).

  The antenna unit 31 has, for example, a structure in which a loop antenna (including a peripheral circuit thereof) in which a conductor is wound in a coil shape around ferrite is embedded in a block-shaped resin, and has one end (left side in FIG. 1). ) Is connected to a communication unit (not shown) inside the vehicle or inside the door. The antenna unit 31 has a substantially cylindrical shape with a polygonal or circular cross section.

  The antenna unit 31 includes, for example, a keyless entry including an in-vehicle device that includes a communication unit that communicates with a mobile key possessed by a user, and an operation permission unit that permits a predetermined operation based on a communication result with the mobile key. Used as an antenna of a communication unit in the system, a signal for requesting authentication (authentication request signal) is transmitted to the portable key.

  The antenna unit 31 includes an in-vehicle device including a receiving unit that receives a signal from a portable key held by the user based on a user operation, and unlocks / locks the door based on the signal from the portable key. You may use as an antenna of the receiving part in the remote keyless system to perform.

  The door switch 41 is constituted by, for example, a well-known push switch, and is for the user to unlock / lock the door. A wire harness 42 connected to one end of the door switch 41 (left side in FIG. 1) is connected to a control unit (not shown) inside the vehicle or inside the door. In the keyless entry system, a response signal corresponding to the above-described authentication request signal is received from the portable key, and the control unit included in the in-vehicle device performs authentication based on the received response signal. When the switch 41 is operated, the door is unlocked / locked according to the situation of the vehicle. For example, the authentication is performed by collating the ID of the portable device included in the response signal with the ID stored in advance in the in-vehicle device.

  The handle main body 51 is formed with a fulcrum arm portion 52 that serves as a fulcrum for the rotation operation of the door handle 1 at one end in the longitudinal direction (left side in FIG. 1), and at the other end in the longitudinal direction (right side in FIG. 1) It includes a retaining portion 53a that defines the pivoting direction of the door handle 1 and prevents the pivoted door handle 1 from slipping out of a base member (not shown) assembled to the vehicle door outer panel. A guide arm portion 53 is formed.

  The handle body 51 is formed with guides 56 a and 57 a for arranging the wire harness 32 and guides 56 b and 57 b for arranging the wire harness 42.

  Further, the handle main body 51 is formed with a boss portion 59 that is substantially concentric with the insertion hole 58 penetrating in the direction of the handle cover 11 and protrudes in a substantially cylindrical shape. Further, a boss portion 13 is formed at a portion facing the boss portion 59 inside the handle cover 11. The handle body 51 and the handle cover 11 have a boss portion formed in the handle cover 11 with a screw 60 inserted into the insertion hole 58 (boss portion 59) from the lower side (that is, the vehicle door side) in FIG. It is fixed by being fastened to 13.

  The door handle 1 is attached to the vehicle door via the base member (not shown) to which the fulcrum arm portion 52 and the guide arm portion 53 are attached. The door handle 1 is attached to the vehicle door in detail, and the details of the structure of the door handle 1 are well-known door handle structures such as Japanese Patent Application Laid-Open No. 2008-013960. It is based on.

  The attachment form to the door handle 1 of the buffer member 21 and the antenna unit 31 is demonstrated using FIGS. FIG. 2 shows a top view of the vehicle door handle device of FIG. 1, and FIG. 2 (a) shows a top view of the handle main body 51 with the handle cover 11 assembled, and FIG. ) Shows a top view with the handle cover 11 removed in FIG. 3 shows a cross-sectional view taken along the line AA in FIG. 2B, and FIG. 4 shows a cross-sectional view taken along the line BB in FIG. 2B.

  First, the door switch 41 is accommodated in the door switch accommodating portion 55. The wire harness 42 passes from the groove 61 formed at the bottom of the handle body 51 and the branch guide 62 to the periphery of the boss 59 (upper side of FIG. 2B), and is locked by the guides 56b and 57b to the door side. Wired.

  In the example of FIG. 1, the antenna unit 31 is inserted in the direction of the arrow C from the side where the wire harness 32 is not connected into the cylindrical buffer member 21.

  The inner surface of the buffer member 21 is formed so as to be fixed to the surface of the antenna unit 31. The buffer member 21 and the antenna unit 31 may be bonded using a double-sided tape or an adhesive. Thereby, the backlash of the antenna unit 31 is suppressed, and even when the door handle is bent or shocked, the buffering member 21 can absorb and mitigate the bending or shock more efficiently.

  Then, the buffer member 21 in which the antenna unit 31 is inserted is accommodated in the antenna unit accommodation portion 54. At this time, stopper portions 63 and 64 are respectively formed on the left and right ends of the antenna unit housing portion 54 in the longitudinal direction (left and right direction in FIG. 1), and the end portions in the longitudinal direction of the buffer member 21 or the antenna unit 31 are formed. Each of them is in contact with the stopper portion so that the buffer member 21 or the antenna unit 31 does not rattle. The wire harness 32 passes through the periphery of the boss portion 59 (the lower side in FIG. 2B), is locked by the guides 56a and 57a, and is wired to the door side.

  Further, the housing 41 of the door switch 41 is provided with a protruding portion 41a, and a part of the buffer member 21 or the right end portion in the longitudinal direction of the antenna unit 31 (a portion not in contact with the stopper portion 64) is in contact with the protruding portion 41a. In this way, the door switch 41 may also serve as a stopper.

  As shown in FIG. 4, the buffer member 21 has a cross-sectional shape so as to be pressed against any of the upper inner wall surface 54 a, the side inner wall surface 54 b, and the bottom inner wall surface 54 c of the antenna unit housing portion 54 having a substantially rectangular cross section. (That is, the thickness of each part) is defined. As a result, there is no gap between the buffer member 21 and the handle body 51 and the handle cover 11. Of course, the inner surface shape of the buffer member 21 does not cause a gap with the antenna unit 31.

  In FIG. 1, the length of the buffer member 21 in the longitudinal direction (left and right direction in FIG. 1) is shorter than the length of the antenna unit 31 in the longitudinal direction (both ends of the antenna unit 31 are both ends of the buffer member 21. May be substantially the same as or longer than the length of the antenna unit 31 in the longitudinal direction.

  Further, the buffer member 21 may have a substantially bag shape so as to cover an end portion (for example, the stopper portion 64 side) in the longitudinal direction of the antenna unit 31. At this time, after the antenna unit 31 is inserted into the buffer member 21, the opening of the substantially bag-shaped buffer member 21 may be closed. In this case, the buffer member is fixed so as to cover the entire surface of the electric member, and the buffer member is also filled in the gap between the antenna unit 31 and the stopper portions 63 and 64, so that the stability of the assembly and the door handle 1 can be improved. The influence (deformation etc.) on the antenna unit 31 due to the bending can be suppressed.

  FIG. 5 shows another example of the configuration of the buffer member 21. As shown in FIG. 5A, the cylindrical structure of the buffer member 21 is formed by a single sheet-like member. The buffer member 21 is wound around the surface of the antenna unit 31 with the longitudinal direction of the antenna unit 31 (the left-right direction in FIG. 5A) as a winding axis. The buffer member 21 forms an adhesive layer 21 g coated with a double-sided tape or an adhesive for fixing to the antenna unit 31.

  The length L1 in the longitudinal direction of the antenna unit 31 and the length L2 of the side of the buffer member 21 corresponding to the longitudinal direction of the antenna unit 31 are substantially the same, but may be L1> L2 or L1 <L2. In the case of L1 <L2, the above-described substantially bag shape can be obtained by closing the end portion in the longitudinal direction of the buffer member 21 (the portion facing the stopper portions 63 and 64).

  FIG. 5B shows a cross-sectional view (corresponding to the BB direction of FIG. 2) in a state where the buffer member 21 is wound around the body surface of the substantially cylindrical antenna unit 31 (the adhesive layer is not shown). The seam 21a formed by the two ends of the wound buffer member 21 may also be fixed with an adhesive or the like. Further, the thickness of the buffer member 21 is defined so as to be crimped to any inner wall surface (the upper inner wall surface 54a, the side inner wall surface 54b, and the bottom inner wall surface 54c) of the antenna unit housing portion 54. In the example of FIG. 5B, the thickness of the portion that is crimped to the upper inner wall surface 54a is thicker than the other portions. Of course, the thickness of the buffer member 21 may be uniform. In this case, the buffer member 21 has a thickness capable of being crimped to a portion where the length of the gap between the antenna unit 31 and the inner wall surface of the antenna unit housing portion 54 is the largest (in the example of FIG. 5B, the upper inner wall surface 54a). have.

  FIG. 6 shows another example (cross-sectional view) of the configuration of the buffer member 21 of FIG. In FIG. 6, the buffer member is a sheet-like member having a substantially constant thickness, and is wound around and secured to the surface of the body portion of the substantially cylindrical electrical component. In this example, the length exceeds one circumference in the winding direction of the outer peripheral portion of the electrical component, and the portion exceeding the circumference is fixed to the buffer member that is secured to the electrical component.

  The buffer member 21 is formed of one sheet-like member, wound from the top surface of the antenna unit 31 as a starting point, and a portion 21b exceeding the circumference of the body surface of the substantially cylindrical antenna unit 31 is wound first. It is an overlapping portion that overlaps the member 21. The buffer member 21 is fixed to the antenna unit 31 (or the buffer member 21) with an adhesive or the like.

  In FIG. 6, it seems that there is a gap between the antenna unit 31 and the buffer member 21 or between the inner wall surface and the buffer member 21, but this is due to drawing restrictions and the gap is not formed in the actual configuration. Not.

  As shown in FIG. 6, the portion having the largest gap between the antenna unit 31 and the inner wall surface (the upper inner wall surface 54a, the side inner wall surface 54b, and the bottom inner wall surface 54c) of the antenna unit accommodating portion 54 (in the example of FIG. 6, the upper inner wall surface The buffer member 21 (overlapping portion 21f) can be pressure-bonded to the upper inner wall surface 54a by winding the buffer member 21 so as to form an overlapping portion in a gap with respect to 54a. Alternatively, a portion (21b) exceeding one circumference of the outer peripheral portion of the antenna unit 31 may be folded and crimped to the upper inner wall surface 54a. Thereby, a member (elastic member) having a substantially constant thickness can be used as the buffer member 21, and the manufacturing process of the buffer member 21 can be simplified.

  FIG. 7 shows another example (cross-sectional view) of the configuration of the buffer member 21 of FIG. In FIG. 7, the overlapping portion 21b of the buffer member 21 of FIG. 6 is formed using another buffer member 21e. Moreover, the buffer member 21 is comprised by several sheet-like members like the upper member 21c and the lower member 21d. Of course, the joint between the upper member 21c and the lower member 21d may be fixed with an adhesive or the like. The buffer member 21e and the upper member 21c may be integrally formed. Thereby, even when the antenna unit 31 has a shape in which it is difficult to wind one sheet-like member, the buffer member can be fixed at a predetermined position of the antenna unit 31 by dividing the buffer member. .

  The buffer member 21 may be wound spirally around the longitudinal direction of the antenna unit 31 as an axis.

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
