Description

The present invention relates to a display device mounted on, for example, an automobile or a motorcycle.

Conventionally, as a display device of this type, for example, the one described in the following Patent Document 1 is known. The display device described in Patent Document 1 is a horizontal display unit (information display body) configured to be transparent and located at a position one step lower than the fluoroscopic unit so as to project around the fluoroscopic unit. Corresponding to the upper housing (housing) having a wall portion (overhanging portion), a vertical wall portion (connecting portion) connecting the fluoroscopic portion and the horizontal wall portion, and an opening provided at a predetermined position of the fluoroscopic portion. It includes an elastic member to be arranged, and performs a predetermined function by operating a switch element arranged behind the elastic member in accordance with a pressing operation of the elastic member by an operator.

Japanese Unexamined Patent Publication No. 2017-49027

In the display device described in Patent Document 1 described above, a part of the elastic member protrudes to the front side of the fluoroscopic portion, which is the operator side. In recent years, the elastic member is elastic to the front side of the fluoroscopic portion. A resin operating member that can be operated by the operator is covered and fixed on the front side of the elastic member without causing a part of the member to pop out, and the outermost surface of this operating member is substantially flush with the outermost surface of the fluoroscopic portion. Further, there are some configurations in which an operation unit composed of an elastic member and an operation member (with a relatively lightened interior) is arranged adjacent to the immediate outside of the standing wall portion.

That is, in implementing the configuration, as an example, it is conceivable that the opening is provided not in the fluoroscopic portion but in the horizontal wall portion of the upper housing, and the operation unit is arranged in the opening provided in the horizontal wall portion. .. Therefore, in the configuration, the operation unit is composed of an operation member that can be operated by the operator and an elastic member that can fix the operation member, and a switch is arranged behind the elastic member as the operation member is operated. When the element operates, a predetermined function is performed.

By the way, when the operating member (with the inside relatively lightened) is fixed to the front side of the elastic member in this way, the operation member is operated on the upper housing in order to prevent the operating member from being removed from the elastic member. It is necessary to attach a dedicated fixing member for fixing the member. For example, in order to press the substantially frame-shaped flange portion (bulging portion) provided so as to bulge all around the lower end side of the operating member from above, the fixing member is fixed to the upper housing by an appropriate fixing means. The structure was adopted.

However, when it is desired to arrange the operating member adjacent to the standing wall portion immediately outside, one side wall portion facing (corresponding to) the standing wall portion of the operating member so that the operating member and the standing wall portion do not interfere with each other when the operating member is operated. It is necessary to eliminate (meatless). Then, with the elimination of the one side wall portion, the flange portion could not be provided all around the operating member, and as a result, the flange portion was not in the shape of a substantially frame but in the shape of a U.

That is, at this time, when the operator presses the operation member (with the lightening of one side wall portion) with a finger, the operation member may be shaken in the left-right direction or the up-down direction, and the operability of the operation member may be considered. There is a problem that it adversely affects (or the feeling given to the operator when operating the operating member).
Therefore, an object of the present invention is to provide a display device that does not adversely affect the operability of the operating member in order to deal with the above-mentioned problems.

In the present invention, a see-through portion configured to allow the information display body to be seen through, an overhanging portion extending around the see-through portion, and a connecting portion connecting the outer peripheral edge of the see-through portion and the inner peripheral edge of the overhanging portion are provided. It is provided with a housing and an operation unit arranged corresponding to an opening provided in the overhanging portion, and the operation unit can be fixed to an operation member that can be operated by an operator and the operation member. In a display device that is composed of the elastic member and performs a predetermined function by operating a switch element arranged behind the elastic member in accordance with the operation of the operating member, the overhanging portion is the fluoroscopic portion. It is provided at a position lower than the formation position of the portion, projects around the fluoroscopic portion so as to surround the fluoroscopic portion, and is arranged so as to be adjacent to the connecting portion when the display device is viewed from the operator side. The operation member to be operated has a wall portion in which all of the portions facing the connecting portion are missing as missing portions, and the portion excluding the missing portion extends toward the overhanging portion side. A positioning portion is provided on one of the overhanging portion and the operating member, and a positioned portion on which the positioning portion is positioned is provided on the other side.

Further, in the present invention, the overhanging portion is provided with a plurality of the positioning portions, the operating member is provided with the plurality of the positioned portions to which the plurality of the positioning portions are respectively positioned, and the plurality of the positioning portions are provided. Is provided in the vicinity of the boundary between the overhanging portion and the connecting portion.

According to the present invention, it is possible to provide a display device that can achieve the desired object and does not adversely affect the operability of the operating member.
