Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an electronic device such as an in-vehicle audio device that is removably attached to an instrument panel or the like,
In particular, the present invention relates to a handle rotation device in which a handle for pulling out and carrying a device is rotatably supported with respect to a device body.

[Conventional technology]

FIG. 5 to FIG. 7 show conventional vehicle-mounted audio equipment by side views for each operation. This on-vehicle audio equipment is detachably attached to the instrument panel of a car, and can be removed when getting off the car.
After that, it can be carried around.

Reference numeral 1 is a chassis, and 2 is a nose provided in front of it.

Reference numeral 12 is a handle. The handle 12 is rotatably supported by a support pin 10 provided on the side of the nose 2. Lock lever 14 on handle 12 by pin 13
Are connected. The lock lever 14 has an arcuate groove 14a.
Is provided, and the groove 14a is guided by the guide pin 15 provided on the side portion of the main body chassis 1. A lock piece 14b is integrally provided at the tip of the base of the lock lever 14, and the handle 12 has a nose 2 as shown in FIG.
The lock piece 14b is inserted into the lock hole 20a of the base 20 to be mounted and is locked so that the chassis body does not come out when the lower edge is in the posture.

A drive lever 16 is rotatably supported on the support pin 10. One end of the drive lever 16 projects toward the front of the operation surface A and its tip is bent to form an operation piece 16a. An extruding piece 16b is bent at the other end of the drive lever 16, and this is the rear edge 1 of the handle 12.
It is locked to 2a. When the handle 12 can be held, the operating piece 16a of the drive lever 16 is pressed from the state shown in FIG. When the operating piece 16a is pressed, the drive lever
16 rotates about the support pin 10, the pushing piece 16b pushes the handle 12, and the handle 12 turns to the posture shown in FIG. At this time, the lock lever 14 rotates together with the handle 12, and the lock piece 14b at the front end of the rear part thereof comes out of the lock hole 20a to unlock the device. By holding the handle 12 from the posture shown in FIG. 6 and rotating it to the front to raise the handle 12 as shown in FIG. 7 and pulling the handle 12, the device can be pulled out from the mounted base 20.

[Problems to be solved by the device]

In the above-mentioned conventional example, the operation piece 16a is formed integrally with the end portion of the drive lever 16. Therefore, when the operation piece 16a is pushed and the drive lever 16 rotates, the operation piece 16a moves along the rotation locus as shown in FIG.

On the other hand, when pressing the operation piece 16a with a finger, as shown in FIG. 6, a linear pressing force F is generally applied to the operation piece 16a in a direction perpendicular to the operation surface A. When the operation piece 16a moves along the rotation locus with respect to the linear action line of the pressing force F, the operation feeling when pressed with a finger becomes very bad. Further, when the operation piece 16a is pushed, the rotation load of the drive lever 16 and the rotation load of the handle 12 act as a resistance force to the finger, but the operation piece 16a has a structure that rotates. The resistance force acting on the finger applying the linear pressing force F increases, and a large operation force is required to rotate the handle 12, resulting in poor operability.

The present invention is to solve the above-described conventional problems, and when the handle is turned forward by a predetermined angle by a pressing operation with a finger, the touch feeling of the electronic device is improved and the resistance to the finger is reduced. It is intended to provide a moving device.

[Means for solving problems]

The handle rotation device according to the present invention is provided with a handle that rotates from a first posture along the edge of the operation surface to a second posture standing in front of the operation surface with the side portion of the operation surface as a fulcrum. The electronic device is provided with a push button that linearly moves in a direction perpendicular to the operation surface, and a drive lever that is rotated by the pressing force when the push button is pressed. A push-out portion is provided at an end portion on the opposite side to the end portion of the button that receives the pressing force, for rotating the handle in the first posture by a predetermined angle in the second posture direction when the drive lever rotates. It is characterized by that.

Further, in the above, the drive lever is rotatably supported with respect to a fulcrum common to the handle, and the drive lever receives a pushing force from the push button at one end sandwiching the fulcrum and the other end thereof. It is preferable that the extruded portion is formed.

[Action]

In the above means, a push button that linearly moves in a direction perpendicular to the operation surface is provided, and when a pressing force by a finger is applied in a direction perpendicular to the operation surface, the push button moves along the operation line of the finger. It is pressed linearly and moves backward. When the push button is pushed and recedes linearly, this pushing force acts on one end of the drive lever to rotate the drive lever. The turning force of the drive lever is applied to the handle by the push-out portion provided at the other end, and the handle rotates forward by a predetermined angle to a position where it can be easily gripped by hand. Since the push button linearly moves in the same direction with respect to the pressing force of the finger in the direction perpendicular to the operation surface, the feeling of the pressing operation becomes good. Also, the rotational resistance acting on the finger from the push button is reduced, and the operability is greatly improved.

Further, if the rotation fulcrum of the drive lever and the rotation fulcrum of the handle are made common, the support structure of the handle and the drive lever can be simplified, and both the handle and the drive lever can be arranged in a narrow space. It will be possible.
