Description

[Detailed Description of the Invention] The present invention relates to a display device that is installed in a vehicle instrument or the like and displays information or a warning.

Cars and motorcycles are generally equipped with display devices to inform the driver of the vehicle's status, such as turn signal operation status, gear position display, engine oil pressure status, headlight high beam display, and speed warning display. This is often placed on the dial of instruments such as speedometers or decorative display boards due to visibility issues and installation space constraints. Connected to a display lamp,
A display lens is provided on the dial plate in correspondence with this lamp, and when the lamp is turned on, the display lens is illuminated to notify the driver. In this case, for example, as disclosed in Japanese Utility Model Publication No. 49-35813, a light-shielding pipe is installed between the display lens and the display lamp by connecting the space, and this light-shielding pipe allows light to be removed from the lamp. This prevents the irradiated light from leaking to the outside.

Therefore, in the case of a display device with the above configuration, the number of parts such as display lamps, display lenses, light-shielding pipes, etc. increases, and a large installation space is required, which may restrict the mounting position of the display device. There is.

The present invention solves the above problem by forming a mounting hole at an appropriate location on a resin holder, forming a plurality of elastic engagement claws continuous with the mounting hole, and forming a detection part to be displayed. An engaging portion is formed on the side circumferential surface of the self-luminous element electrically connected to the self-luminous element, the self-luminous element is inserted into the mounting hole of the resin holder, and the elastic engagement claw is fitted into the engaging portion. At the same time, a support portion for supporting and holding the resin holder is formed inside a housing that houses a meter, etc., and the spontaneous element is placed on the dial front side of the dial plate disposed on the front side of the housing. The present invention aims to construct a display device that has advantages such as forming a display hole that allows the display to be viewed, does not take up as much installation space as in the past, and is easy to assemble.

The present invention will be described in detail below based on Examples.

1 to 3 show one embodiment of the present invention, and in these figures, 1 is an indicator instrument that is installed at a suitable place in a vehicle, and inside the housing 2 of this indicator instrument 1 is an instrument body 3. is housed and fixed, and a dial 4 is fixed above the instrument body 3.
Instructions from a pointer 5 attached to a meter body 3 are read by comparing them with a display section 6 such as numerical values and scales provided on a dial plate 4.

7 is a self-luminous element that is electrically connected to a detection unit that is a display target such as engine oil pressure and emits light when the display target is in a state that requires an alarm.
It is an LED (light emitting diode), and an engagement rib 7A as an engagement portion is formed protrudingly on the circumferential surface of the LED 7, and a terminal 8 protrudes from the bottom surface of the LED 7.
An electric cord 8A is connected to the housing 2, and the electric cord 8A is routed to the outside of the housing 2, and is connected to the above-mentioned oil pressure detection section (not shown).

Reference numeral 9 is a resin holder, and the LED is inserted into the mounting hole 9A of this holder 9, and the engaging rib 7A of the LED 7 is inserted into the engaging claw 9B that extends downward continuously from the mounting hole 9A of this holder 9. They are engaged to fit and lock. Reference numeral 10 denotes a columnar support that is integrally formed with the housing 2, and has a projection 11 formed at its upper end. The holder 9 is formed with an engagement hole 9C that engages with the protrusion 11, and by engaging the protrusion 11 with the engagement hole 9C, the holder 9 is supported and held on the support portion 10 on the housing 2 side. It is configured to allow 12
is a display hole provided in the dial 4, and the LED 7
The LED 7 is provided at a position corresponding to the LED 7 on the dial plate 4 when the holder 9 fitted and locked is supported and held by the support part 10, so that the LED 7 faces the front side of the dial plate 4.

Reference numeral 13 denotes a lamp for night illumination of the indicator 1, which is fixedly mounted in a lamp mounting hole 14 formed in the housing 2 via a lamp socket 15.

According to the above configuration, there is no need to attach a display lens to the dial plate as in the conventional case, and since the support part 10 provided inside the housing 2 takes up less space than a conventional cylinder, the space inside the housing 2 is saved. The LED 7 can be used effectively, the housing 2 can be made smaller, and the LED 7 can be attached to the holder 9, the holder 9 can be supported and held on the support part, and the dial plate 4 can be placed on top of it, making assembly easy. can be obtained.

Furthermore, in the embodiment, the holder 9 is supported and held by the support part 10 by making the support part 10 column-shaped and having a protrusion 11 at the tip thereof and providing a locking hole 9B in the holder 9 and engaging these parts. The holder 9 may be provided with a protrusion and the support portion 10 may be provided with an engagement hole. Furthermore, as in another embodiment shown in FIG. 4, a stepped portion 10' may be provided on the side wall of the housing 2' to support it. Even if both ends of the holder 9' are supported and held as parts, the same effect as in the above embodiment can be obtained. Further, an engaging groove 7'A is provided on the side periphery of the LED 7' shown in FIG. 4, and the engaging claw 9'B of the holder 9' is engaged with this engaging groove 7'A. However, even in this case, the same effects as in the above embodiment can be obtained.

In addition, although the embodiment shows an example in which the present invention is applied to an indicating instrument, the present invention is not limited to this, and the present invention can be achieved even when applied to, for example, a liquid crystal display instrument, and the self-luminous element does not need to be an LED. Needless to say.

As described above, according to the present invention, the space required in the housing of the instruments for display is small, so the inside of the housing can be used effectively, the instrument housing can be downsized, and the assembly work is easy. It is possible to provide a display device.
