Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an instrument device installed in a vehicle, a ship, or an agricultural machine.

(Prior Art) In general, various types of equipment such as vehicles, ships, and agricultural machinery are equipped with a display mechanism that centrally displays the operating status and abnormalities of various instrument devices and parts. In such instrument devices, a display housing for housing a display mechanism is sometimes set up independently of the instrument housing that houses the instrument body, but the instrument housing that houses the instrument body of the indicating instrument Since the display housing and the display housing housing the display mechanism are separately provided, the number of parts tends to increase, resulting in high costs.

Therefore, as shown in FIGS. 4 and 5, in a vehicle, for example, a motorcycle, an indicator housing 1 attached to an appropriate position on the vehicle body has an indicator housing 1A that houses an instrument body 2 and a display that houses a display mechanism 3. It consists of a housing for the part 1B,
This housing 1 is made of synthetic resin material.

In addition, the display housing 1B has an illumination light 6 such as a lamp disposed at the bottom of the illumination chamber 5 divided by the partition wall 4 facing toward the interior of the display housing 1B. A transparent display board 7 is disposed on the side.

Furthermore, notches 8 are provided on the front side periphery of the display housing 1B, and protrusions 9 are provided on the periphery of the display plate 7 in the same number and shape as the notches 8 of the display housing 1B, and can be fitted into the notches 8, The display plate 7 is fixed to the display housing 1B by means such as press fitting.

In addition, when fixing the display board 7 to the display housing 1B, this protrusion 9 is caused by the fact that each display board 7 has the same shape.
This is for positioning B and the display board 7 to prevent misplacement, and they are provided at different positions on the periphery of the display board 7. Along with this, the display housing 1
The position of the notch 8 provided in B is also provided at a predetermined position in accordance with the protrusion 9 of the display board 7 provided.

Further, between the display boards 7, there is a partition frame 10 that covers the entire surface of the partition wall 4 so that the partition wall 4 is not visible.
A display window 10A is formed in the partition frame 10 at a position corresponding to the display board 7.

Further, a see-through plate 11 is disposed on the entire surface side of the housing 1 of the indicating instrument for reading the display state of the instrument body 2 and the display board 7 of the display mechanism 3. The outer side and the inner side of the housing 1 are formed so as to be kept watertight.

A nighttime illumination lamp 6 is installed on the bottom side of the meter housing 1A to read the indication status of the meter body 2.

Therefore, in the case of such an indicating instrument, an instrument housing 1A that houses the instrument body 2 and a display mechanism 3 are required.
By integrally forming the display section housing 1B containing the display section housing 1B, the number of parts and the assembly process can be reduced.

(Problems to be Solved by the Invention) In the conventional technology, the display housing 1B is divided into a plurality of sections by the partition wall 4,
Since the internal volume of the lighting room 5 partitioned by the partition wall 4 is relatively small, the internal temperature of the lighting room 5 is increased by the heat generated by the lighting lamp 6 when the lighting lamp 6 is turned on, and this temperature increase causes As a result, the partition wall 4 of the display housing 1B may change color, and the locally heated portion of the partition wall 4 may become deformed.

In order to solve this problem, it is conceivable to provide a hole in the display housing 1B so that the heat inside the lighting chamber 5 is released to the outside of the lighting chamber 5, but it is possible to use a synthetic resin material. Since the entire housing 1 is formed, the holes may not be formed during molding of the housing 1 depending on the direction of mold removal, and the holes for ventilation are provided after molding the housing 1. Although it is possible to do so, it is difficult to manufacture.

In addition, when molding the entire housing 1 from synthetic resin material with a mold, uneven parts are formed to provide ventilation holes and positioning notches to prevent misplacement of the display board. This makes designing the mold itself complicated.

(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, the instrument housing that houses the instrument body is molded from a synthetic resin material, and a display mechanism to which a display mechanism consisting of an illumination light and a display board is attached. The instrument housing and the display housing are integrally formed by molding the instrument housing from a synthetic resin material, and the display housing forms an illumination chamber of the display mechanism. In an instrument device in which a lighting lamp is installed on the bottom side of the lighting chamber and a display board is placed on the top side of the lighting chamber, at least one notch is provided on the open side of the upper end of the housing for the display section of the lighting room, and the A protrusion that matches the shape of the notch is provided so that when the display board is fitted into the display housing, the protrusion is located at the position of the notch, and between the lowest wall surface of this protrusion and the deepest wall surface of the notch, a The device is characterized in that a ventilation path is provided that communicates the meter body with the meter body.

(Embodiment of the invention) Hereinafter, an embodiment of the invention will be described based on the attached drawings, taking an instrument device of a vehicle, for example, a motorcycle as an example. are given the same reference numerals and detailed explanations thereof will be omitted.

At least one periphery on the front side of the display housing 1B connects the inside and outside of the illumination chamber 5.
Two notches 8 are provided at the periphery of the display board 7.
A protrusion 7 that matches the shape of the notch 8 is provided so that it can be fitted into the notch 8, and the display plate 7 is assembled and fixed to the display housing 1B by a method such as press fitting. The thickness of the protrusion 9 and the depth of the notch 8 are set so that a gap is created between the lowest wall surface 9A and the deepest wall surface 8A of the notch 8. A ventilation path 12 is formed that communicates between the outside, that is, the illumination chamber 5 of the display housing 1B and the instrument housing 1A. In this case, when molding the housing 1, the notch 8 is formed continuously from the upper edge of the display housing 1B, so the mold can be easily designed.
It is possible to construct a ventilation mechanism for an indicating instrument that is easy to mold. Further, in this embodiment, at least one notch 8 is installed in the display housing 1B of each illumination chamber 5, and each illumination chamber 5 of the display housing 1B is provided with a ventilation passage 12 formed by the notch 8. For example, when the lighting lamps 6 disposed in each lighting room 5 are turned on, the heat generated by the lighting lamps 6 is removed by the ventilation path 12. The temperature rise within the room 5 can be suppressed.

Note that the protrusion 8 provided on the display board 7 is provided to prevent the display board 7 from being incorrectly placed in the display housing 1B, which would otherwise occur due to the fact that the display boards have the same shape. In technology,
By setting the thickness of the protrusion 7 and the depth of the notch 8 to predetermined dimensions, the display housing 1B
The interior and exterior sides of the illumination chamber 5 are continuous to provide ventilation between the illumination chamber 5 and the instrument housing 1A.

Therefore, since the notch 8 for positioning to prevent incorrect placement of the display board 7 can also be used as the ventilation path 12, the notch can be formed continuously from the front edge of the display housing 1B, making it easy to remove the metal. A mold can be designed, and a ventilation mechanism for an indicating instrument that is easy to mold can be constructed.

FIG. 3 shows a second embodiment of the present invention, in which two notches 8 are provided on the open front side of the display housing 1B of each illumination chamber 5 partitioned by a partition wall 4. Each ventilation passage 12 is formed by these two cuts 8. At this time,
The position of the housing 1 of the indicator instrument attached to the vehicle body is such that the surface of the transparent plate 11 of each instrument body 2 and display mechanism 3 is positioned relative to the driver's line of sight so that the instrument body 2 and display mechanism 3 can be easily seen by the driver. It is installed with a slight slope so that it is as vertical as possible. At this time, one of the two ventilation passages 12 is provided as much as possible above the open side of the display housing 1B of each lighting room 5, and the remaining one is provided as much as possible on the lower side. It is designed to enhance the effect of air convection. In this case, the ventilation passage 12A located on the upper side is formed so that the width of the cut 8 is wide, and the ventilation passage 12B located on the lower side is formed so that the width of the cut 8 is increased.

In addition, in this embodiment, the ventilation path is made as wide as possible so that the convection effect is not impaired.
The positioning protrusion 9 is fitted into only the cut on the lower side of the two ventilation passages.

This allows the circulation of air inside and outside the lighting room 5 to be further enhanced by increasing the width and depth of the notch 8, and the position and number of the ventilation passages 12 can be set appropriately. It is possible to increase the convection effect by
