  However, in the above-described conventional example, if there is an error in the dimensions of the corresponding portions of the front and back covers and the switch unit, rattling of the switch unit or lifting of the connecting part of the front and back covers occurs. It is necessary to increase the accuracy, and there is a drawback that the production efficiency is lowered.

  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 that can securely fix a switch unit without requiring dimensional accuracy between multiple parts. To do.

  The door handle is formed by connecting a front cover 1 that constitutes a portion that is mainly exposed to the outside in a state where the door handle is attached to a vehicle door, and a back cover 2 on the side facing the door surface. The switch unit 3 is stored in the internal space formed by the covers 1 and 2. The switch unit 3 is a unit in which a switch operation unit and an operation detection unit are housed in a case. An electrostatic sensor switch or the like can be used in addition to a unit that detects an operation by a push button that is a switch operation unit.

  The switch unit 3 is temporarily held at a predetermined position by the elastic locking of the elastic locking portion 4 formed on either the case of the switch unit 3 or the front or back cover to the locking target. The bullet locking part 4 allows the locking object to pass once with the elastic deformation during the mounting operation of the locking object, and locks the locking object by returning to the original position at the locking position.

  One or a plurality of the bullet locking portions 4 can be arranged in consideration of the temporarily held state. In addition, the switch unit 3 is temporarily held by, for example, standing a leg piece having a claw for locking at the tip thereof so as to correspond to the entire side wall of the switch unit 3, and pushing the switch unit 3 temporarily. As in the case, the switch unit 3 is slid and positioned in a box-shaped region in which only one side wall is opened, and the switch unit 3 is opened from the open end. This includes the case where temporary holding is performed in cooperation with other members, as in the case where only the movement is restricted by the bullet locking portion 4.

  It is sufficient that the temporary holding state is maintained at least until the connection operation of the front and back covers 1 and 2 is completed. In the connected state, the pressing piece 5 formed on the opposite cover locks the bullet locking portion 4. Restricts movement in the release direction and is permanently fixed.

Therefore, in the present invention, the switch unit 3 can maintain a temporary holding state without rattling by using the urging force of the bullet locking portion 4. The holding piece 5 only needs to regulate the unlocking of the bullet locking portion 4 and does not need to function to prevent rattling. Therefore, it is not necessary to increase the dimensional accuracy in relation to the switch unit 3 or the like. . As a result, in order to prevent rattling, it is only necessary to manage the dimension between the switch unit 3 and the cover on the side where the switch unit 3 is temporarily held, so that the production efficiency is increased. Problems such as lifting of the connecting portion between the front and back covers 1 and 2 are reliably prevented.
Moreover, according to the present invention,
A door handle of a vehicle formed by connecting front and back covers 1, 2 and storing a switch unit 3 in an internal space,
The switch unit 3 is provided with a suitable number of bullet locking portions 4 and is temporarily held by either the front or back cover 1 (2).
When the front and back covers 1 and 2 are connected, the door 5 of the vehicle is fixed at a predetermined position by restricting the movement in the unlocking direction of the bullet locking part 4 by the pressing piece 5 protruding from the other cover 2 (1). It is also possible to provide a handle.

  According to the present invention, the switch unit can be securely fixed without requiring dimensional accuracy between multiple parts.

  As shown in FIG. 1, the door handle is formed with hinge pieces 1a and operating projections 1b at both ends, and the hinge piece 1a arranged toward the vehicle front side is connected to the door via an appropriate base member. Fixed. In the fixed state, the door handle can be horizontally rotated around the rotary shaft 9 and the operating protrusion 1b at the rear end (hereinafter, “front and rear” and “front and back” are defined based on the mounting posture to the vehicle). By rotating the door handle so that the door is pulled out, it is possible to unlock the door lock device (not shown) that maintains the closed state of the door.

  As shown in FIG. 1 (c), the door handle is formed by connecting front and back covers 1, 2 and communicates with a portable authentication signal transmitter (not shown) possessed by the user in the internal space. The antenna 8, a push button switch (switch unit 3) that functions as a switch for starting communication at the time of locking, and an electrostatic sensor 10 that functions as a switch for starting communication at the time of unlocking are stored.

  As shown in FIG. 2, the front cover 1 has the hinge piece 1 a and the operating protrusion 1 b at the front and rear ends, and provides an external shape of the door handle in a front view shown in FIG. A button exposure opening 1 c for exposing the operation head 3 a of the push button switch 3 is opened at the rear end of the front cover 1.

  On the other hand, the back cover 2 is formed in a shape that closes the opening of the front cover 1 in the back surface direction. As shown in FIG. 5, the back cover 2 has the communication antenna 8, the push button switch 3, and the electrostatic sensor 10, which are pre-assembled in advance, and the connection protrusion 2 a protruding from the rear end. While being locked to the cover 1, the front end is screwed with a screw 11 and connected to the front cover 1. The external connection cable 12 drawn from the communication antenna 8 or the like is wired forward in the internal space inside the door handle, and then drawn out from the wiring lead-out portion 2b of the back cover 2 to the inside of the door and connected to the control portion 13. (See FIG. 1C).

  When the control unit 13 detects an operation on the push button switch 3 or the electrostatic sensor 10, the control unit 13 starts communication with the portable authentication signal transmitter described above from the communication antenna 8 and is output from the portable authentication transmitter. Authenticate the authentication signal. When authentication by the control unit 13 is established, when an operation to the push button switch 3 is caused by activation by driving an appropriate actuator, a locking operation is performed, and an operation to the electrostatic sensor 10 is caused by activation. Performs the unlocking operation.

  Further, as shown in FIGS. 5 and 6, the push button switch 3 mounted on the rear end portion of the back cover 2 is a locking projection that protrudes from two opposing edges of the button case 3 b that supports the operation head 3 a. 3c, and the back cover 2 is provided with a slide stopper 7 corresponding to the locking projections 3c. The slide stopper 7 is placed in such a position that the side where the locking protrusion is formed is aligned with both side edges of the back cover 2 and the operation head 3a faces the button exposure opening 1c of the front cover 1. It is determined by the position of the push button switch 3, and the slide stopper 7 contacts or approaches the front end surface of the locking projection 3 c at this position.

  The height of the slide stopper 7 is set to be approximately equal to the distance from the bottom wall of the push button switch 3 to the surface of the locking projection 3c, and the guide piece 6 extends backward from the free end of the slide stopper 7. Projected. The length of the guide piece 6 in the front-rear direction substantially coincides with the length of the locking projection 3c, and a hook-shaped bullet locking portion 4 projects from the rear end thereof.

  The push button switch 3 is fixed to the back cover 2 configured as described above by sliding the push button switch 3 forward as shown in FIGS. 6 (a) and 6 (b). The rear end of the back cover 2 is an open end so that the slide operation can be performed, and is closed by the rear end wall portion of the front cover 1 after the front cover 1 is connected.

  When the push button switch 3 is slid forward, the front end wall of the locking projection 3c eventually comes into contact with the bullet locking portion 4. As shown in FIG. 6 (a), the free end of the elastic locking portion 4 protrudes toward the back side as compared with the surface wall of the locking projection 3c, and thus comes into contact with the locking projection 3c. As a result, a component force toward the surface side is generated in the bullet locking portion 4. Due to the generation of the component force, the guide piece 6 on which the elastic locking portion 4 is formed is elastically deformed, and as a result, as shown in FIGS. 6 (c) and 6 (d), it interferes with the path of the locking projection 3c. The bullet locking portion 4 that has been ridden on the surface wall of the locking projection 3c allows the push button switch 3 to advance.

  When the push button switch 3 is further slid forward from this state and the elastic locking portion 4 coincides with the rear end wall of the locking protrusion 3c, the elastic locking force of the guide piece 6 causes the elastic locking portion 4 to become the original. It returns to the position and is elastically locked to the rear end of the locking projection 3c. As shown in FIGS. 6E and 6F, in the locked state, the locking protrusion 3c is restricted from moving backward by the impact locking part 4 and forward from the slide stopper 7. At the same time, the movement to the front side is restricted by the guide piece 6 and held at the locking position.

  After the push button switch 3 is fixed to the back cover 2 together with the antenna 8 and the like as described above, when the front cover 1 is connected, the guide piece 6 is attached to the front cover 1 as shown in FIGS. The pressing piece 5 restricts the movement toward the surface side, that is, the movement of the bullet locking part 4 in the unlocking direction, and the push button switch 3 is completely prevented from being detached and moved.
