Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for electronic equipment, and particularly to a mounting device suitable for mounting electronic equipment on a vehicle.

Traditionally, it has been used as a mounting device for in-vehicle electronic devices such as car audio, in-vehicle wireless communication devices, and car phones.
A locking portion is provided on both sides of the electronic device, and a frame for attaching the electronic device is provided with an engaging portion that engages with the locking portion. 2. Description of the Related Art There is an electronic device mounting device in which a plate spring is provided and the plate spring is pressed into contact with the device and fixed by operating an operating section.

However, in conventional mounting devices of this type, the pressing force of the leaf spring is generally weak, and if the elasticity of the leaf spring is made strong, the operation part cannot be pressed properly, so it is necessary to install it in a vibration-proof manner. It was not sufficient as a mounting device for certain types of in-vehicle equipment.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to provide a mounting device for electronic devices, etc., which not only allows easy attachment and detachment of electronic devices, but also allows devices to be fixed by pressure contact with strong elastic force. be.

In order to achieve the above object, the present invention includes a frame having locking claws that are inserted into locking grooves formed on both sides of an electronic device, and an inclined guide groove formed on the circumferential side of the frame. A guide shaft extending toward the electronic device, an operating lever having a ring portion with a protrusion formed on the inner peripheral surface to be guided in the guide groove, and a pressure spring slidably provided on the guide shaft. The press spring is pressed against the electronic device by a rotationally operated operation lever.

Hereinafter, preferred embodiments of the mounting device according to the present invention will be described based on the drawings.

FIG. 1 shows a preferred embodiment of the mounting device according to the present invention, and FIG. 2 shows a front view of the device of the embodiment shown in FIG.

In FIG. 1, locking grooves 12 are formed on both sides of an electronic device 10 and extend in the front-rear direction for mounting the device. These locking grooves 1
The width of the groove is expanded toward the upper side of the electronic device 10 at two locations on the front side and in the middle of the electronic device 10, and these are used as locking portions 12a and 12b.

The frame 14 of this device is bent into a U-shape as shown in FIG.
A book locking pawl 14a is formed. The frame 14 is formed with an attachment hole 14b for attaching and fixing the frame to the lower side of a vehicle's dart boat, and an attachment hole 14c for attaching the guide shaft 16.

The guide shaft 16 is shown in FIG. 5, and in FIG. 5, two mounting holes 16a are formed on the upper surface of the guide shaft 16 for mounting to the frame 14. In addition, in the present invention, an inclined guide groove 16 is formed on the circumferential surface of the guide shaft 16.
In this embodiment, this guide groove 16a is formed from the upper surface of the guide shaft 16.

In this embodiment, a disc-shaped stopper 18 is provided on the lower side of the guide shaft 16, and two stopper claws 18a are formed on the side peripheral surface of the stopper 18.

As can be understood from FIGS. 1 and 2, the coil spring 20 is first fitted onto the guide shaft 16, and then the pressure spring 22 is applied as shown in FIG. 6, and the operation shown in FIGS. The levers 24 are sequentially fitted onto the outside. Therefore, as shown in FIG.
2 has a hole 22a into which the guide shaft 16 is inserted.
Further, the operating lever 24 has a ring portion 24 in which projections 24a guided by the guide groove 16a are formed at two locations on the inner peripheral surface. Four protrusions 24c are formed on the lower surface of this ring portion 24b, and these protrusions 24c
are inserted into two grooves 22b formed to surround the hole 22a.

Incidentally, steps are provided at both ends of the pressure spring 22, and disk-shaped rubber plates 22c are adhered to the four corners of the steps, and punching is performed so as to surround the groove 22b and reach the vicinity of each rubber plate 22c. The stopper claw 18a of the stopper 18
are inserted into these punched parts.

After the coil spring 20, the pressure spring 22, and the operation spring 24 are sequentially fitted to the outside as described above, the guide shaft 16 is fixed to the lower surface of the frame 14 with the screw 26. Therefore, in this assembled state, the coil spring 20 urges the pressing spring 22 and the ring portion 24b of the operating lever 24 toward the lower surface of the frame 14, that is, upward in the drawing. Furthermore, when the operating portion 24d of the operating lever 24 is rotated, the protrusion 24a of the ring portion 24b is guided to the guide groove 16a, so that the lever 24 moves downward along the guide shaft 16 and presses the pressing spring 22. The pressed spring 22 can be pressed down from above.
can press the top surface of the electronic device 10 by the rubber plates 22c provided at the four corners.

A preferred embodiment of the mounting device according to the present invention has the above configuration, and its operation will be explained below.

In order to mount the electronic device 10 in a vehicle, the frame 14 is first fixed to the underside of the dashboard of the vehicle. Then, the locking claws 14a of the frame 14 are fitted into the locking grooves 12 of the electronic device 10, and the locking portions 14a and 12 are engaged with each other.
2a, 12b are pushed in until they reach the locking claw 14a.
d is rotated, and the operating lever 24 is guided by the guide shaft 16 and moves downward while rotating, so that the rubber plate 22c of the pressing spring 22 is pressed against the electronic device 1.
0, so that the electronic device 10 is held between the locking claw 14a and the pressing spring 22.

Note that when the operating lever 24 is rotated, the rotational deviation of the press spring 22 is prevented by the stop claw 18a of the stopper 18, and the press spring 22 applies sufficient pressing force to the top surface of the electronic device. When the operating lever 24 is rotated until the lever 24 is turned, the protrusion 24c comes into contact with the inner surface of the end of the groove 22b of the pressing spring 22 and is locked.

According to the mounting device for electronic equipment, etc. according to the present invention,
When the operating lever is rotated, the protrusion formed on the ring portion of the operating lever is guided by the inclined guide groove formed on the guide shaft, and slides the pressing spring in the form of a leaf spring, thereby causing the device to move elastically. Since the device can be pressed and fixed, the pressure spring can be slid like a jack, so even if the pressure spring is strong, it can be moved and the device can be pressed and fixed with strong elastic force. be able to. In addition, since the device can be attached and detached by simply rotating the operating lever, it is easy to operate, making it ideal as an attachment device for in-vehicle electronic devices.
