Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a front detachment mechanism for an electronic device, for example, a front detachment mechanism for attaching and detaching a nosepiece unit provided at a front portion of a main body to an electronic device for a compact disc. is there.

[0002]

[Prior art]

 Generally, in order to prevent theft, this kind of electronic device is configured so that when it goes out, the nosepiece unit on the front side is removed and carried, and when it comes back into the vehicle, it is attached and put in a usable state. It has a front detachment mechanism.

[0003]

[Problems to be solved by the device]

 However, such a conventional front detachment mechanism has a problem that it has a complicated structure using a lever with a pin crimped, a coil spring, etc., and the number of parts is large and the manufacturing cost is high.

The present invention has been made in view of such conventional problems, and uses parts such as a spherical engaging member, a lever having a fitting hole into which the spherical engaging member fits, a conical spring, and the like. It is an object of the present invention to provide a front detachment mechanism which has a simple structure and has a small number of parts and caulking points, and which reduces the manufacturing cost.

[0005]

[Means for Solving the Problems]

 The present invention includes a spherical engagement body that is removably attached to both sides of a nose piece unit that is detachably and rotatably attached to a front portion of a body case of an electronic device, and a rotatably attached to the body case. A lever formed with a fitting hole into which the spherical engagement body is fitted; a release key attached to the nose piece unit for operating the lever to release the fitting between the spherical engagement body and the fitting body; And a release spring attached to the inside of the nosepiece unit.

[0006]

[Action]

 In the present invention, when the nose piece unit is pushed in, the spherical engagement body fits into the fitting hole of the lever and becomes in a locked state, and when the release key is pressed, the tip of the release key rotates the lever to fit the spherical engagement body. The nosepiece unit will be in a half-opened state when it is disengaged from the dowel hole and the open spring urges it so that it can be removed from the case.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 are views showing an embodiment of a front detachment mechanism of an electronic device according to the present invention.

First, the configuration will be described. 1 and 2 show a front detachment mechanism (hereinafter simply referred to as a front detachment mechanism) of a car audio which is an electronic device. The front detachment mechanism includes a nosepiece unit 2 in a front part of a main body case 1 of the electronic device. It is detachably attached as explained.

A locking hole 3 is formed at the base end of a nose piece unit (hereinafter abbreviated as unit) 2, and the locking hole 3 is formed in a hook portion 4 provided at the front part of the main body case 1. It is designed to be detachable and rotatable. On both sides of the tip of the unit 2, there are provided spherical engagement bodies which are attached to the support member 5 so as to be retractable and retractable and are made of steel balls 7 urged outward by springs 6. A release key 9 biased outward by a spring 8 is provided near the support member 5. Further, an opening spring 10 composed of two conical springs is attached to the inner side of the central portion of the unit 2.

A lever 11 is provided at the left end of the body case 1. As shown in FIGS. 5 and 3, the lever 11 is composed of fitting pieces 12 and 12 extending on both sides and a hook-like engaging piece 13 extending rightward from the fitting pieces 12 and 12. The pieces 12, 12 are pivotally supported by the shaft 14, and a fitting hole 15 for fitting the steel ball 7 is formed at the tip portion. The lever 11 is biased clockwise by a leaf spring 16.

Next, the operation will be described. In the present invention, when the unit 2 is pushed with the engaging hole 3 attached to the hook 4 as shown in FIG. 1, the unit 2 rotates around the hook 4 as a fulcrum, and the steel ball 7 is fitted into the fitting hole 15 of the lever 11. The unit 2 is locked to the main body case 1 in the state shown in FIG.

When the release key 9 is pressed in this state, the lever 11 rotates counterclockwise against the leaf spring 16 and the fitting hole 15 is disengaged from the steel ball 7 as shown in FIG. As a result, the unit 2 becomes free, and by the biasing of the opening spring 10, the unit 2 is opened halfway forward as shown in FIG. 1 and can be removed from the hook 4.

Although the steel ball 7 is used as the spherical engagement body in the above-mentioned embodiment, it is also possible to use a pin having a hemispherical end at the tip instead of this.

[0014]

[Effect of device]

 As described above, according to the present invention, the unit is locked by fitting the spherical engaging member and the fitting hole of the lever, and the lock is released by the release key. It can be assembled without secondary processing such as welding, and the number of parts is small and the manufacturing cost can be reduced.
