Description

[Detailed Description of the Invention] The present invention relates to a display device in an electronic device such as a vehicle-mounted communication device.

In particular, in the case of a vehicle-mounted communication device equipped with a frequency display section, the frequency display section is often difficult to see because there are restrictions on the installation location within the vehicle and the position and posture of the viewer.

In order to improve this point, there are some models that allow the entire front part to be rotated to change the direction, but this makes the structure extremely complicated,
The cost is quite high and the appearance is bad.

The entire communication device may be mounted at an angle using a bracket, but in that case, a large amount of mounting space is required, a special bracket is required, which is expensive, and the mounting appearance is extremely poor.

The present invention attempts to solve such problems.

Hereinafter, the present invention will be explained based on the drawings.

The one shown is an in-vehicle communication device, 1 is a main body case, 2 is a front case, 3 is a frequency display section equipped on the front case, 4, 5, 6 are various operation knobs, and 7 is a front case. , a microphone plug.

The front case 2 is made of synthetic resin, has the front and top surfaces open at the frequency display section 3, and has a window 24 having left and right side walls 21, 22 and a bottom side 23.
A frequency display section 3 is mounted on the window so as to be movable up and down.

The frequency display section 3 is provided with a display case 31 made of synthetic resin that is movably fitted into the window 24, and the display case has a transparent plate 32 on the front, and a frequency display display and various indicators (not shown) inside. A plurality of touch switches 33 for frequency switching, calling, memory, scan/cancel, etc. are provided on the lower edge of the front surface.

In addition, the display case 31 has an open rear surface and a top wall 31.
A pair of recesses 34, 3 with a semicircular cross section on the left and right of the rear edge of a.
4 are provided in the left-right direction, and the concave portion is provided on the upper edge of the window 24 in correspondence with the convex portion 25 having an arcuate cross section.
25 so as to be rotatably engaged with the bottom wall 31b, and an abutment step 35 facing rearward is formed halfway on the inner surface of the bottom wall 31b.
A protrusion 36 having a semicircular cross section is horizontally provided slightly behind the step, and an engagement groove 37 is formed between the protrusion and the step 35, and the engagement groove is connected to the bottom side 23 of the window 24. The left wall 31c is made to correspond to the engaging protrusion 26 horizontally installed on the lower surface of the front end thereof so as to be able to engage and disengage freely, and the rear edge of the bottom wall 31b is also made to abut against the front surface of the engaging protrusion 26. A long hole 38 having an arc shape centered on the convex portions 25, 25 having an arcuate cross section is bored in the hole 38, and the long hole is engaged with the protrusion 27 protruding from the left wall 21 of the window 24. and the elongated hole 38, when the engagement groove 37 is engaged with the engagement protrusion 26, the display case 31 rotates and the bottom wall 31b
The protrusions 27 are positioned at the other ends of the elongated holes with their rear edges abutting the front surface of the engagement protrusion 26, and hooks protrude to the right on the rear edge of the right wall 31d. 39, and the hook is inserted into the elongated hole 3 as described above.
When the protrusion 27 is located at the other end of the window 2
It is made to abut against the rear edge of the right wall 22 of No. 4.

The bottom side 23 of the window 24 is curved in an arc shape in accordance with the rotation of the display case 31, and the long hole 38 has a corrugated edge so as to be locked to the display case 31 during rotation. is forming.

With the above configuration, the frequency display section 3 can be rotated from the horizontal direction to the inclined direction in the display case 31, and in the horizontal state, the engaging groove 37
This state is retained by the engagement between the bottom wall 31b of the display case and the front surface of the engagement protrusion 26 in the inclined state, and by the abutment between the rear edge of the bottom wall 31b of the display case and the front surface of the engagement protrusion 26. When connecting or disconnecting, press the bottom wall 3 of the display case.
A slight elastic deformation between 1b and the bottom edge 23 of the window is utilized. The range of rotation is secured by the elongated hole 38 and the protrusion 27.

By the way, since the above-mentioned locking and holding in the inclined state is performed by deep engagement between the rear edge of the bottom wall 31b of the display case and the front surface of the engagement protrusion 26, it will not disengage even if the various touch switches 33 are operated from the front. When the window is to be removed, the portion P on the lower surface of the front case 2 immediately behind the display housing 31 is pushed up, and the bottom side 23 of the window is passively elastically deformed.

The one shown is an in-vehicle communication device, but
The same applies to various other electronic devices.

According to the present invention, only the display part such as the frequency display can be rotated arbitrarily and can be directed in a direction where it can be easily viewed. Even if there are restrictions on the position and posture of the display, it can be viewed without any problems by rotating the display, and since only the display is rotated, it looks great.
A large force is not applied to the rotation and support means, and it is sufficient that the rotation and support means are integrally molded in the synthetic resin molding of the display case 31 and the front case 2, and the specific structure of the rotation and support means is sufficient. In the display case 31 with the rear surface open, the top wall 31a
A pair of recesses 34, 34 with a semicircular cross section on the left and right sides of the rear edge
are provided in the left-right direction, and the concave portions are made to correspond to the convex portions 25, 2 with an arcuate cross section provided on the upper edge of the window 24.
5, a rearwardly facing abutment step 35 is formed halfway on the inner surface of the bottom wall 31b, and a protrusion 36 having a semicircular cross section is horizontally provided slightly behind the step. , an engagement groove 37 is formed between the protrusion and the stepped portion 35, and the engagement groove can be freely engaged and detached from the engagement protrusion 26 provided horizontally on the lower surface of the front end of the bottom side 23 of the window 24. In addition, the rear edge of the bottom wall 31b is also configured to abut against the front surface of the engagement protrusion 26, so the above-mentioned integral molding can be easily performed, and there is no need to use screws, tools, etc. It is extremely easy to assemble, and of course there is no need for adjustment, so costs can be kept low.
In addition, when installing inside the car, it can be installed horizontally and easily using a normal bracket.
It looks good when installed, requires less installation space, and is inexpensive to install.
