Description

  The present invention relates to a vehicle door handle.

As a door handle of a vehicle formed by connecting a plurality of portions, the one described in Patent Document 1 is known. In this conventional example, the door handle is formed by connecting a handle body (front cover) and a cover (back cover) that closes an opening formed in the front cover. The back cover is connected to the front cover by crimping the front end of the back cover and screwing the rear end.
Japanese Patent Laying-Open No. 2005-307463

  However, in the above-described conventional example, the connection of the front and back covers requires a screwing operation, and thus has a drawback that the assembling workability is poor.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide a vehicle door handle with good assembling workability.

  When an electronic component is mounted on the door handle A, the door handle A is attached to the door 10 in order to attach the electronic component or to secure a space for the external connection cable 15 of the electronic component. In the state, it is formed by connecting a front cover 1 constituting a part mainly exposed to the outside and a back cover 2, ie, a back cover 2 on the side facing the door surface.

  In the present invention, the connection between the front and back covers 1 and 2 is performed by causing the either one of the front and back covers to slide relative to the other to shift the bullet locking means 5 to the locked state.

  The slide is performed in a state where separation (peeling) in both front and back directions is restricted, and a slide protrusion 3 protruding from one of the covers is slidably fitted to the other slide guide 4. Done.

  The bullet locking means 5 is composed of a locking part and a locked part that interferes with the locking part during the sliding operation, and elastically deforms either the locking part or the locked part by the sliding operation. Thus, the passage to the locking position is permitted, and the state is shifted to the locking state by utilizing the elastic return to the original position at the locking position. In the locked state, both the covers are restricted in the removal direction, that is, the movement toward the slide start end side, and the connected state is maintained.

  Therefore, in the present invention, the connecting operation is completed only by sliding the front and back covers 1 and 2 to each other, so that screwing or the like is unnecessary, and workability is improved.

  The front and back covers 1 and 2 can be laminated, for example, simply by connecting them in the front and back direction. However, the front cover 1 is formed in a C-shaped cross section that is open in the back direction, and When the cover 2 is fitted and formed so as to close the opening 7, the appearance can be improved. In this case, prevention of peeling of the front and back covers 1 and 2 can be realized by fitting the side wall portion of the back cover 2 and the inner wall of the front cover 1 in the front and back directions.

  Further, when the urging means 6 for urging the back cover 2 in the sliding direction in the connected state is provided on the front and back covers 1 and 2 and brought into pressure contact with the slide end position restricting portion, rattling can be prevented.

  The biasing means 6 can be formed by projecting a cantilever-like portion from either the front or back cover, other than using a spring or the like. The biasing means 6 is formed like a cantilever because it biases further in the overstroke direction from the slide end position, unlike the normally biased slide end position to the slide start end side. When the biasing means 6 is used, the structure can be simplified by giving a predetermined initial deflection at the start of sliding.

Especially when there is relative movement in the direction perpendicular to the slide direction before the slide starts,
For example,
The back cover 2 is fitted in the open portion 7 of the front cover 1 that is opened in the back direction and has a C-shaped cross section,
On the side wall of the opening portion of the front cover 1, a door handle A is formed in which an appropriate number of slide guides 4 and an introduction path 8 that is open to the back side starting from one end of each slide guide 4, 4. If you want to
The biasing means 6 is formed in a cantilever shape that is elastically deformable and that presses the mating contact portion 9 with an elastic restoring force accompanying the elastic deformation to give a biasing force,
In addition, the elastic deformation of the biasing means 6 can be configured to occur due to the contact of the counterpart contact portion 9 accompanying the movement of the slide protrusion 3 in the introduction path 8.

  In this case, the biasing means 6 interferes with the mating contact portion 9 when the slide protrusion 3 moves in the direction orthogonal to the slide direction in which the slide protrusion 3 moves in the introduction path 8 and is given an appropriate initial deflection. Even when the slide protrusion 3 moves from this state to the slide end, the entire amount of bending of the biasing means 6 is not eliminated, and the bias toward the slide end position is performed by the remaining deflection.

Further, the hinge tongue 11 for providing the rotation center C to the door 10 at both ends of the exposed portion from the door 10 in the attached state to the door 10 and the door lock using the movement around the rotation center C in accordance with the rotation operation. An operating projection 13 for operating the device 12;
When the hinge tongue piece 11 is formed integrally with either the front or back cover and the operation protrusion 13 is formed on another cover, the hinge tongue piece 11 and the operation protrusion 13 are operated during the slide operation. Since it can be used as a force applying member, the assembly workability is improved.

  According to the present invention, since the front and back covers can be connected without requiring a screwing operation, the assembly workability can be improved.

  As shown in FIG. 1, the door handle A is connected to the door 10 in a posture with the left side facing the front of the vehicle in FIG. The door 10 is kept closed by locking a door lock device (not shown) to the vehicle body. In the connected state, the door handle A is horizontally rotated around the rotation center C to lock the door lock device 12. To release.

  Further, the door handle A accommodates an antenna 14 used for communication with a portable transmitter held by the user, and an external connection cable 15 connected to the antenna 14 is provided in front (in the present specification). The front / rear side and the front / rear side are determined based on the mounting posture to the vehicle.

  As shown in FIG. 2, the door handle A has a C-shaped cross section, and provides a front cover 1 that provides an outer surface shape in a front view when attached to the door 10, and a handle for operation. It is formed by connecting the back cover 2. The back cover 2 is formed in a shape capable of closing the opening 7 to the back surface of the front cover 1, and the antenna 14 is attached prior to the connecting operation of the front cover 1.

  As shown in FIG. 3, a hinge tongue 11 protrudes forward from the front end portion of the back cover 2 and at the rear end portion is a counterpart contact portion 9 for biasing means 6 described later. The projecting piece projects backward. In addition, a hemispherical pressure contact protrusion 2a is provided at an appropriate position of the back cover 2 so as to protrude in the surface direction.

  Further, a connecting protrusion 2b protrudes from the center of the edge of the back cover 2 toward the front surface, and a slide protrusion 3 protrudes outward from an appropriate position of the connecting protrusion 2b. . A hemispherical projection 2c that constitutes the elastic locking means 5 is provided in a protruding manner at the center of each slide projection 3, 3,... And the front end of the back cover 2.

  On the other hand, as shown in FIG. 4, the front cover 1 is provided with an operating protrusion 13 at the rear end, and the front end cooperates with a hemispherical protrusion 2 c formed at the front end of the back cover 2. Thus, the hemispherical concave portion 1a constituting the bullet locking means 5 is formed. Further, a groove-shaped introduction path 8 that is open to the rear surface side and extends to the front surface side is recessed in the inner wall surface of the side wall, and a bottomed slide guide 4 extends from the end of the introduction path 8 toward the front. The At the front end of the slide guide 4 is formed a hemispherical recess 1a that constitutes the elastic locking means 5 in cooperation with the hemispherical protrusion 2c formed on the slide protrusion 3 of the back cover 2.

  Further, a biasing means 6 is formed at the rear end of the front cover 1. The urging means 6 is projected from the rear surface of the front cover 1 and formed in a cantilever shape.

  Therefore, in this embodiment, as shown in FIG. 5 (a), the front and back covers 1 and 2 are connected first with the slide protrusion 3 facing the introduction path 8 of the front cover 1, and then with FIG. As shown in b), the slide protrusion 3 is moved to the front cover 1 side so as to enter the introduction path 8. When the front and back covers 1 and 2 are approached, the protruding piece 9 on the back cover 2 side is elastically deformed so as to push the urging means 6 of the front cover 1 arranged at a position interfering with the movement path, while sliding the guide 4 Move to the base end of.

  After the slide protrusion 3 reaches the slide guide 4, the deflection of the biasing means 6 is maintained in a state where the slide protrusion 3, that is, the back cover 2 moves forward and reaches the slide end position, The projecting piece 9 of the back cover 2 is pressed forward by an elastic restoring force based on this bending.

  As shown in FIG. 5 (b), the slide projection 3 is prevented from reaching the slide guide base end by the hemispherical projection 2 c formed at the front end of the back cover 2 riding on the front cover 1. In this state, when the front and back covers 1 and 2 are pressed against each other to elastically deform the front and back covers 1 and 2, the slide protrusion 3 enters the slide guide 4, and then the back cover 2 is slid to the slide stroke end position. The hemispherical protrusion 2c that has advanced while climbing on the front cover 1 falls into the hemispherical concave portion 1a of the front cover 1 by an elastic restoring force and becomes locked. At the same time, the other hemispherical protrusion 2c is also elastically locked to the hemispherical recess 1a on the front cover 1 side, and movement to the slide start end side is prevented.

  Moreover, each press-contact protrusion 2a, 2a ... presses the ceiling wall 1b of the front cover 1 in a connection state, and prevents rattling in the front and back directions.
