Description

  The present invention relates to a vehicle door handle that includes a door handle main body and a molding member attached to the door handle main body and performs an opening operation of a vehicle door.

  In a vehicle door handle (hereinafter simply referred to as “door handle”), a decorative molding member may be attached in order to improve the appearance. The molding member is subjected to decorative surface treatment (for example, plating). For this molding member, a technique disclosed in Patent Document 1 is disclosed.

  Conventionally, when assembling a door handle body and a molding member, the bending claws provided at a plurality of locations of the molding member are bent and fitted into the claw insertion grooves provided in the door handle body, and further, the plurality of locations are tightened with fixing screws. It is crowded. In this case, when the door handle is used, there is a possibility that the flexing claw of the molding member and the claw insertion groove of the door handle main body are rubbed and abnormal noise is generated. In order to prevent this, a soundproof material (nonwoven fabric or the like) must be attached to the portion where both are rubbed, and the number of work steps increases.

In addition, since a large force is required when fitting the bending claw portion of the molding member, the load during assembly is large and workability is poor. And when the bending nail | claw part of a molding member is inserted in the nail insertion part of a door handle main body, there exists a possibility that a surface treatment part may be damaged. Furthermore, it is difficult to remove the molding member once assembled.

  According to a fifth aspect of the present invention, on the premise of the first aspect of the present invention, the door handle main body is provided with a molding member mounting groove for fitting the molding member, and the molding is provided. By arranging the side wall portion of the molding member fitted into the member mounting groove and the inner wall surface of the molding member mounting groove in opposition to each other, the molding member assembled to the door handle body is provided with the door handle. It is characterized by preventing rattling in the width direction of the main body.

  In the invention of claim 5, the molding member assembled to the door handle main body enters the molding member mounting groove of the door handle main body, and the side wall portion thereof is disposed close to the inner wall surface of the molding member mounting groove. Thereby, it is prevented that the molding member rattles in the width direction, and the generation of abnormal noise is further suppressed.

  Examples of the present invention will be described. 1 is a perspective view of the door handle 101 with the door handle body 1 and the plating molding 2 separated from each other, FIG. 2 is a plan view of the door handle 101, FIG. 3 is a front sectional view of the door handle 101, and FIG. FIG. 5 (a) is a cross-sectional view taken along line X1-X1 in FIG. 3, and FIG. 5 (b) is a cross-sectional view taken along line X2-X2.

  As shown in FIGS. 1 to 4, the door handle 101 of the first embodiment is attached to an outer panel (not shown) of a vehicle door and is held when the door is opened. 1 and a decorative molding member (plating molding 2) attached to the door handle main body 1 are provided. Both the door handle body 1 and the plating molding 2 are made of a resin material. In addition, although the molding member of a present Example is the plating molding 2 by which the surface was plated, this surface treatment may be other than plating.

  First, the overall shape of the door handle body 1 will be described. The door handle body 1 has a shape suitable for a user to hold, and is attached to an outer panel of a vehicle door at a front end portion in the longitudinal direction (left side in the drawing view of FIG. 2). A pivoting fulcrum portion 3 is provided as a pivotal fulcrum 3 that is a pivotal point when the handle body 1 is pivoted in a direction to be raised from the outer panel. Further, a stopper portion 4 is provided at the rear end portion in the longitudinal direction of the door handle body 1 so as to project the door handle body 1 raised from the outer panel at a certain angle. Formed in the upper part of the door handle body 1 is a molding member mounting groove 5 for mounting the plating molding 2 over substantially the entire length in the longitudinal direction. The inner width of the molding member mounting groove 5 is slightly wider than the width of the plating molding 2. In addition, a through hole 7 through which the fixing screw 6 is inserted is provided in the front portion of the door handle body 1.

  Next, the plating mall 2 will be described. As shown in FIGS. 1 and 2, the entire plating molding 2 is curved like a bow. And when the upper surface is mounted in the molding member mounting groove 5 of the door handle body 1, it has a curved surface shape that is continuous with the upper surface of the door handle body 1 (see FIG. 5). A pair of skirt portions 8 is suspended. Further, a nut fitting portion 9 is provided at the front end portion of the back surface portion 2 a of the plating molding 2, and a hexagon nut 11 is fitted to the nut fitting portion 9 in a non-rotating state. The nut fitting portion 9 is provided at a position directly above the through hole 7 of the door handle main body 1 in a state where the door handle main body 1 and the plating molding 2 are assembled together. Each skirt portion 8 of the plating molding 2 is provided with a plurality of (four in the present embodiment) insertion portions 12 at a predetermined interval in the longitudinal direction. Each insertion portion 12 includes a pair of side wall portions 13 extending from the pair of skirt portions 8, a bottom wall portion 14 provided by connecting lower ends of the pair of side wall portions 13, And an insertion claw 15 protruding forward from substantially the center in the width direction. In the case of the door handle 101 of the first embodiment, the width of each insertion claw 15 of the plating molding 2 is the same over its entire length.

  As shown in FIGS. 1 and 3 to 6, the molding member mounting groove 5 in the door handle body 1 has a plurality of (this embodiment) at positions corresponding to the respective insertion portions 12 of the plating molding 2. In this case, the same number of four protrusions 16 as the insertion portions 12 of the plating molding 2 are provided. Both end portions in the width direction of each protrusion 16 have a stepped shape, and when the plating molding 2 is assembled to the door handle body 1 on the stepped surfaces, each skirt portion 8 of the plating molding 2 is formed. A molding member abutting portion 16a for abutting is formed. Each protrusion 16 has a height that comes into contact with the back surface portion 2a of the plating molding 2 when the plating molding 2 is assembled to the door handle body 1, and the upper surface portion 16b thereof It has a curved surface corresponding to the bow shape of the plating molding 2. And in each lower end part of each projection part 16, each insertion groove 18 which inserts insertion claw 15 of each insertion part 12 of plating molding 2 is provided. The bottom surface of each insertion groove 18 is flush with the groove bottom portion 17 of the molding member mounting groove 5, and its inner height is slightly larger than the thickness of the corresponding insertion claw 15. Further, the depth length L1 is slightly longer than the protruding length L2 of the corresponding insertion claw 15 (see FIG. 7A).

  As shown in FIGS. 7A and 7B, in the case of each insertion groove 18 of the present embodiment, the inner wall surface 18a has an inner width W2 at the innermost portion rather than an inner width W1 at the inlet portion. Is an inclined surface that is inclined with respect to the axis 19 of the door handle body 1 so as to be small. That is, the width W3 of the insertion claw 15 corresponding to the insertion groove 18 is smaller than the inner width W1 of the inlet portion of the insertion groove 18 and larger than the inner width W2 of the innermost portion (W1> W3> W2). . On the other hand, the outer wall surface 15 a of each insertion claw 15 is a straight surface parallel to the axis 22 of the molding member 2. For this reason, the insertion claw 15 inserted into the insertion groove 18 stops in a state in which each corner portion 21 a of the distal end surface 21 is in contact with the corresponding inner wall surface 18 a of the insertion groove 18. In this state, the axis 19 of the door handle body 1 and the axis 22 of the plating molding 2 are aligned in the width direction. Thereby, each insertion nail | claw 15 of the plating mall 2 is inserted in each insertion groove 18 of the door handle main body 1, and is assembled | attached to the door handle main body 1 by being hooked.

  In the door handle 101 of the first embodiment, an operation when the door handle body 1 and the plating molding 2 are assembled will be described. In addition, although this specification demonstrates the effect | action at the time of assembling by sliding the plating mall 2 with respect to the door handle main body 1 of a stationary state, even if it is the reverse case, it is the same. As shown in FIGS. 6A and 7A, the plating molding 2 is fitted into the molding member mounting groove 5 of the door handle body 1. Each skirt portion 8 of the plating molding 2 and the inner wall surface 5a of the molding member mounting groove 5 of the door handle main body 1 are arranged to face each other with a slight gap e (see FIG. 5A). Each insertion part 12 of the plating mall 2 is arranged immediately behind each corresponding projection 16 in the door handle body 1, and the difference between each insertion claw 15 of the plating molding 2 and each projection 16 of the door handle body 1. The insertion groove 18 is opposed to each other. The plating molding 2 is slid along the insertion direction 23 (longitudinal direction of the plating molding 2) with respect to the door handle main body 1, and each insertion nail | claw 15 is inserted in each insertion slot 18 corresponding. When the axis 19 of the door handle body 1 and the axis 22 of the plating molding 2 are aligned in the width direction (that is, both the axes 19 and 22 are on the same straight line in plan view), the plating molding 2 is slid. The respective corner portions 21a of the distal end surface 21 of each insertion claw 15 and the inner wall surface 18a of each insertion groove 18 are simultaneously brought into contact (point contact in plan view). Thereby, the door handle main body 1 and the plating molding 2 are assembled. The clearance e between the left and right skirt portions 8 of the plating molding 2 fitted in the molding member mounting groove 5 of the door handle body 1 and the inner wall surface of the molding member mounting groove 5 is substantially the same. In other words, the plating molding 2 is assembled with the door handle body 1 being centered.

  Since each insertion claw 15 of the plating molding 2 is inserted and hooked into the insertion groove 18 of the projection 16 of the corresponding door handle main body 1, the plating molding 2 is vertically moved with respect to the door handle main body 1. It will not come off. Further, since the back surface portion 2 a of the plating molding 2 is brought into contact with the upper surface portion 16 b of each projection 16 of the door handle body 1, the plating molding 2 assembled to the door handle body 1 is supported by each projection 16. There is little possibility that the plating molding 2 will dent during use.

  Next, an operation when the plating molding 2 is slid in a state where the axis 19 of the door handle body 1 and the axis 22 of the plating molding 2 do not match in the width direction will be described. In this case, only one corner portion 21a of the front end surface 21 of each insertion claw 15 is first brought into contact with the inner wall surface 18a of the corresponding insertion groove 18 (point contact in plan view). In this state, the plating molding 2 is further slid. Since one corner portion 21a of the insertion claw 15 is slid while being in contact with the inner wall surface 18a of the insertion groove 18 which is an inclined surface, the plating molding 2 gradually moves inward in the width direction. The other corner portion 21a of the insertion claw 15 is brought into contact with the inner wall surface 18a of the insertion groove 18 (point contact in plan view). As a result, the plating molding 2 is centered in the width direction with respect to the door handle main body 1, and the axes 19 and 22 thereof coincide with each other in the width direction.

  When the plating molding 2 is assembled to the door handle main body 1, the nut fitting portion 9 of the plating molding 2 is disposed in the portion of the through hole 7 of the door handle main body 1. A fixing screw 6 inserted into the through-hole 7 from below the door handle body 1 is screwed to a hexagon nut 11 fitted to the nut fitting portion 9 of the plating molding 2. As a result, the plating molding 2 is not slid in the direction opposite to the insertion direction 23 with respect to the door handle body 1 and the plating molding 2 is pressed more firmly against the door handle body 1. As a result, the plating molding 2 is prevented from rattling in the vertical direction and the longitudinal direction with respect to the door handle body 1. Further, since the plating molding 2 is fitted into the molding member mounting groove 5 of the door handle body 1 through a slight gap e, the plating molding 2 does not rattle in the width direction.

  When the door handle main body 1 and the plating molding 2 are separated, the fixing screw 6 is removed, and the plating molding 2 is slid in the direction opposite to the insertion direction 23 with respect to the door handle main body 1, and each insertion claw 15. Need only be extracted from each corresponding insertion groove 18. For this reason, it is easy to separate the door handle body 1 and the plating molding 2.

  In the conventional door handle, the bending claw is fitted in the claw insertion groove, and the contact state is a line contact. On the other hand, in the door handle 101 of the present embodiment, the contact state between the insertion groove 18 of the door handle body 1 and each insertion claw 15 of the plating molding 2 is surface contact. Therefore, when the door handle 101 is used, the plating molding 2 is less likely to move in the vertical direction with respect to the door handle main body 1 (in other words, each difference between the insertion groove 18 of the door handle main body 1 and the plating molding 2). The contact surface with the nail 15 is not easily rubbed), and the generation of abnormal noise is prevented. As a result, the work of attaching a soundproof material to the plating molding 2 becomes unnecessary, and the number of man-hours is reduced. Since the pair of skirt portions 8 of the plating molding 2 is fitted in the molding member mounting groove 5 of the door handle main body 1 through a slight gap e in the width direction, the plating molding is used when the door handle 101 is used. 2 becomes difficult to move in the width direction. Further, since the front end portion of the plating molding 2 is connected to the door handle body 1 by the fixing screw 6, the plating molding 2 is difficult to move in the longitudinal direction when the door handle 101 is used. As a result, the generation of abnormal noise when the door handle 101 is used is further suppressed.

  And since it becomes unnecessary to bend the bending nail | claw provided in multiple places of the molding member like the conventional door handle, there is no possibility of damaging plating at the time of assembling the plating molding 2, and small force It is assembled with.

  In the case of the door handle 101 of the first embodiment, the inner wall surface 18a of each insertion groove 18 provided in each projection 16 of the door handle body 1 is an inclined surface, and each insertion claw 15 of the plating molding 2 is provided. The outer wall surface 15a is along the insertion direction 23 thereof. However, as shown in FIG. 8A, the outer wall surface 15a of the insertion hole 15 may be an inclined surface, and the inner wall surface 18a of the insertion groove 18 may be a straight surface. Further, as shown in FIG. 8B, the outer wall surface 15 a of each insertion claw 15 may be an inclined surface having the same inclination angle as the inner wall surface 18 a of each insertion groove 18. In this case, the outer wall surface 15a of each insertion claw 15 and the corresponding inner wall surface 18a of each insertion groove 18 are brought into contact with each other by line contact. For this reason, the door handle body 1 and the plating molding 2 are more reliably centered. Further, as shown in FIG. 8B, the outer wall surface 15a of the insertion claw 15 may be an inclined surface, and the inner wall surface 18a of the insertion groove 18 may be a straight surface.

  In the case of the door handle 101 of the first embodiment described above, each insertion groove 18 is provided on the door handle body 1 side, and each insertion claw 15 is provided on the plating molding 2 side. However, like the door handle 102 of the second embodiment shown in FIGS. 9A and 9B, the insertion claws 24 protrude from the projections 16 on the door handle body 1 side. Each insertion groove 25 may be provided on the plating mall 2 side.
