(First Embodiment)
As shown in FIG. 1, the vehicle display device 100 according to the first embodiment of the present disclosure is mounted on a vehicle and is installed on an instrument panel 2 facing a seat on which an occupant who visually recognizes the device 100 sits. .. The vehicle display device 100 can display vehicle information toward the visual side where the occupant seated in the seat is located by the information display unit 30.

In the present embodiment, the upper and lower parts are defined so that the vehicle on the horizontal plane is used as a reference. Left and right are defined based on the occupant seated in the seat.

As shown in FIGS. 2 to 4, such a vehicle display device 100 is composed of a case portion 10, a mounting substrate 20, an information display portion 30, a tubular member 50, a translucent member 60, an elastic member 70, and the like. There is.

The case portion 10 is formed by combining the back side case component 11 and the visible side case component 12. The back side case component 11 is formed of, for example, a synthetic resin so as to have a light-shielding property, and covers the mounting substrate 20 from the back side (also referred to as the non-visible side) opposite to the visible side. The visible side case component 12 is formed of, for example, a synthetic resin so as to have a light-shielding property, and partially covers the mounting substrate 20 from the visible side.

The mounting substrate 20 is formed in a flat plate shape by, for example, synthetic resin, and is sandwiched between the back side case component 11 and the visible side case component 12. A light emitting element 31a, a stepping motor 35, and the like are mounted and held on the mounting substrate 20.

The information display unit 30 displays information toward the visual side on the vehicle display device 100. Specifically, the information display unit 30 of the present embodiment has a back side display plate 31, a plurality of pointer units 34, and a translucent display unit 38, and displays by combining these.

The back side display plate 31 is also generally called a dial, and semi-translucent or light-shielding printing is performed on the surface of a translucent base material such as an acrylic resin or a polycarbonate resin as a whole or. It is partially applied and formed into a flat plate. Instead of printing, painting may be applied. Such a back side display plate 31 covers the viewing side case component 12 from the viewing side so that the mounting board 20 is not visually recognized from the viewing side.

By guiding the light from the light emitting element 31a arranged on the mounting board 20 to the back side display board 31, printing or the like is not performed or semitranslucent printing or the like is performed on the back side display board 31. The light emitting area is illuminated from the back side to emit light.

The pointer unit 34 is provided in the left region, the central region, and the right region of the information display unit 30, respectively. Each pointer unit 34 has a pair of stepping motors 35 and a pointer 36. The stepping motor 35 is held on the back side of the mounting board 20.

The guideline 36 integrally has a connecting portion 36a and an indicating portion 36b. The connecting portion 36a is arranged through a through hole formed in the back side display plate 31 and is connected to the rotation shaft of the stepping motor 35. The indicator portion 36b is arranged on the viewing side of the back side display plate 31 and has a needle shape. The pointer 36 rotates according to the output of the stepping motor 35, and information on the vehicle according to the indicated position is displayed. Here, examples of the information displayed by the pointer unit 34 include the speed of the vehicle, the engine speed, the remaining amount of fuel, the current value of the electric motor, and the like.

The translucent display unit 38 displays the design 38a as shown in FIG. 1 by using the translucent display plate 42 arranged on the visual side of each pointer unit 34. Specifically, the translucent display unit 38 includes a light source unit 39 and a translucent display plate 42.

As shown in FIGS. .. The light source unit 39 includes a light source substrate 40 and a plurality of light emitting elements 41 mounted on the light source substrate 40. The plurality of light emitting elements 41 are arranged along the extending direction of the translucent display plate 42 so as to face the outer edge portion 42a of the translucent display plate 42 with a slight gap. A light emitting diode is adopted for each light emitting element 41, and each light emitting element 41 emits light by being connected to a power source through a conduction pattern on the light source substrate 40. The plurality of light emitting elements 41 are provided so as to be able to switch on or off at the same time, and emit light from a light source with substantially the same color and substantially the same brightness as each other. In this way, the light source unit 39 provides the light source light inside the translucent display plate 42.

The translucent display plate 42 is formed translucently with, for example, an acrylic resin or a polycarbonate resin, and has a flat plate shape having a visible side plate surface 38b and a back side plate surface 38c. The viewing side plate surface 38b is formed so as to face the viewing side, and the back side plate surface 38c faces the back side display plate 31 by facing the back side. In the present embodiment, the translucent display plate 42 is provided substantially parallel to the back side display plate 31. Since the translucent display plate 42 is formed to be translucent, the rear side display plate 31 and the pointer portion 34 can be visually recognized by the occupant from the viewing side.

The translucent display plate 42 has a reflection display unit 43 corresponding to the introduction of the light source light from the light source unit 39 into the translucent display plate 42. As shown in FIGS. It has a plurality of 44. The reflection display unit 43 forms a symbol 38a that is macroscopically visible to the occupant by appropriately arranging a plurality of reflection elements 44. In particular, in the present embodiment, the symbol 38a is formed by arranging the plurality of reflecting elements 44 two-dimensionally along the back surface side plate surface 38c while separating them from each other so as to pass through the flat portion 45.

Since each reflecting element 44 has a reflecting surface 44a that reflects the light source light introduced inside the translucent display plate 42 to the visual recognition side, the design 38a shines like a surface light source and is displayed. .. When the light source unit 39 is turned off and the light source light is not introduced into the translucent display plate 42, the symbol 38a is hardly visible because each reflecting element 44 has a fine size and is formed through the flat portion. It has become like.

In particular, as shown in FIG. 1, the symbol 38a of the present embodiment is a scale symbol having the shape of the scale that is the object indicated by the pointer 36, but other symbols may be used.

If foreign matter such as dust, dust, or water invades or adheres to such an information display unit 30, there is a concern that the information display on the information display unit 30 may be hindered or the appearance of the display may be deteriorated by the foreign matter. .. In particular, when foreign matter adheres to the plate surfaces 38b and 38c of the translucent display plate 42 of the translucent display unit 38, when the light source light is introduced into the translucent display plate 38, the foreign matter also shines at the same time as the symbol 38a. The problem becomes more serious because it ends up. In the present embodiment, the following structure that encloses the information display unit 30 by combining the tubular member 50 and the translucent member 60 is adopted with the intention of effectively suppressing the intrusion of such foreign matter. There is.

The tubular member 50 shown in FIGS. 1 to 4, 7 to 12 is generally also referred to as a facing plate. It is formed in a shape. The tubular member 50 has openings 50a and 50b on both the viewing side and the back surface side. Since the surface of the tubular member 50 is formed in a dark color (for example, black), the inner peripheral wall surface portion 51 of the tubular member 50 facing the inner peripheral side creates a sense of depth of the information display unit 30 and is incident. While suppressing the reflection of the incoming external light and improving the visibility of the information display unit 30, it itself is less noticeable.

An inclined surface 53 and a concave groove 54 are provided on the outer peripheral wall surface portion 52 of the tubular member 50 facing the outer peripheral side. The inclined surface 53 is provided over the entire circumference of the tubular member 50 at a position on the visual side of the concave groove 54. The inclined surface 53 is inclined toward the inner peripheral side from the back surface side adjacent to the concave groove 54 toward the visual recognition side connected to the viewing side opening 50a. As a result, the peripheral length of the tubular member 50 gradually increases from the viewing side opening 50a toward the concave groove 54 side.

The concave groove 54 is provided in most of the circumferential range R1 of the tubular member 50 except for a part. As shown in FIGS. Is forming. In particular, the concave groove 54 of the present embodiment has a rectangular shape in the radial cross section, so that it is connected to both sides of the groove bottom surface 54a facing the outer peripheral side and the groove bottom surface 54a via the corners 54c. It also has a groove side surface 54b formed substantially perpendicular to the groove bottom surface 54a.

Further, the tubular member 50 has a regulation flange 55 formed so as to project from the outer peripheral wall surface portion 52 to the outer peripheral side over the entire circumference of the tubular member 50. The regulation flange 55 is formed on the back side of the concave groove 54 in the range in the circumferential direction of the tubular member 50 in which the concave groove 54 is formed, and projects so as to extend the groove side surface 54b on the back side. There is.

Further, as shown in FIGS. Has a protruding guide 56 that protrudes from the tip of the regulation flange 55 to the visual viewing side. The protruding guide 56 has a guide surface 56a that faces the inner peripheral side and faces the inclined surface 53 in the circumferential direction.

It should be noted that such a protruding guide 56 is provided at an auxiliary position because there is a position where it is difficult to form the concave groove 54 at a specific position when, for example, the tubular member 50 is molded.

The translucent member 60 shown in FIGS. 2, 4, 11 and 12 is translucently formed of, for example, an acrylic resin or a polycarbonate resin, and the translucent plate portion 61 and the projecting cylinder portion 62 are integrally formed. There is. The translucent member 60 of the present embodiment is colored in a smoke tone to have a transmittance of about 30%, but may be set to an arbitrary value of 30% or more.

The light transmitting plate portion 61 is formed in a plate shape that closes the entire region of the viewing side opening 50a of the tubular member 50. Since the translucent plate portion 61 has translucency, the back side display plate 31, the pointer portion 34, and the translucent display portion 38 can be visually recognized by the occupant from the viewing side.

The protruding tubular portion 62 is formed in a tubular shape that protrudes from the outer peripheral portion of the translucent plate portion 61 toward the back surface side, and is open to the back surface side. The light-transmitting member 60 is such that the inner peripheral wall surface portion 63 facing the inner peripheral side of the protruding tubular portion 62 faces the outer peripheral wall surface portion 52 of the tubular member 50 with a radius of about the radius of the elastic member 70 described later. It is combined with the tubular member 50. In particular, in the present embodiment, the inner peripheral wall surface portion 63 is entirely formed with an inclined surface so as to be substantially parallel to the inclined surface 53 of the outer peripheral wall surface portion 52.

As shown in FIGS. 13 and 14, the elastic member 70 is formed with elasticity by, for example, an estramer such as synthetic rubber. The elastic member 70 is formed in a ring shape. The natural peripheral length EL (so-called natural length) of the elastic member 70 is set to be about 5 to 9% smaller than the outer peripheral side peripheral length of the visible side opening 50a of the tubular member 50. In particular, the elastic member 70 of the present embodiment has a circular cross section in the radial direction in a natural state.

Such an elastic member 70 is stretched around the outer peripheral wall surface portion 52 in a state of being in contact with the outer peripheral wall surface portion 52 over the entire circumference in the circumferential direction. The elastic member 70 exerts a contraction force on the inner peripheral wall surface portion 52 in a state of being stretched around the outer peripheral wall surface portion 52 by setting the peripheral length EL described above. The elastic member 70 is in a state of being pressed by the tip end portion 64 of the protruding cylinder portion 62 protruding from the visual recognition side toward the elastic member over the entire circumference.

As shown in FIGS. 4, 11 and 12, in the range R1 in which the concave groove 54 is provided in the circumferential direction of the tubular member 50, the elastic member 70 is between the protruding tubular portion 62 and the regulation flange 55. The elastic member 70 is in a pinched state, and the movement of the elastic member 70 to the back surface side is restricted by the regulation flange 55. Here, when the elastic member 70 is pressed by the protruding cylinder portion 62, the outer peripheral side of the elastic member 70 is crushed by the protruding cylinder portion 62 because the tip portion 64 is located on the outer peripheral side of the core of the elastic member 70 (in other words). Then, it is lightly compressed). The elastic member 70 is fitted into the concave groove 54 on the inner peripheral side in combination with this pressing form and the above-mentioned contraction force.

In a state where the elastic member 70 is fitted into the concave groove 54, the elastic member 70 is elastically deformed according to the shape of the concave groove 54 by pressing the protruding cylinder portion 62. As a result, the contact area between the elastic member 70 and the groove bottom surface 54a and the groove side surface 54b of the concave groove 54 is secured, and the sealing property between the tubular member 50 and the translucent member 60 is enhanced.

As shown in FIGS. The movement of the elastic member 70 to the back surface side is restricted by the regulation flange 55. Further, as described above, since the guide surface 56a of the projecting guide 56 faces the inclined surface 53 of the outer peripheral wall surface portion 52, the elastic member 70 is sandwiched between the projecting guide 56 and the outer peripheral wall surface portion 52. It will be in a state of elasticity. By sandwiching the elastic member 70 from four directions in this way, the elastic member 70 is prevented from falling off.

As shown in FIG. 8, in the range L1 of the left and right lateral portions, the concave groove 54 is inclined with respect to the back side display plate 31 and the translucent display plate 42 according to the height dimension of the tubular member 50. is doing. In the range R0 sandwiched between such inclined portions, as shown in FIG. 2, the protruding guide 56 is provided with a concave groove 56b that is recessed toward the outer periphery, and the elasticity is caused by pressing the protruding cylinder portion 62 against the elastic member 70. The member 70 is fitted into the concave groove 56b.

As shown in FIGS. 1 and 3, the maintenance of the pressed state against the elastic member 70 is realized by locking the translucent member 60 with respect to the case portion 10. Specifically, a plurality of locking hole portions 13 are formed on the outer periphery of the visible side case component 12 of the case portion 10. On the other hand, on the outer peripheral side of the protruding cylinder portion 62, a plurality of protruding claws 65 individually corresponding to the locking hole portions 13 are provided. Each protruding claw 65 projects to the back side of the tip portion 64. Then, each protruding claw 65 is locked in the locking hole portion 13 in a state of being inserted into the locking hole portion 13. As a result, the translucent member 60 is locked to the case portion 10 with the tubular member 50 sandwiched between them.

On the lower side of the vehicle display device 100, a case screw flange 14 projecting to the outer peripheral side is provided at a position deviated from the protruding claw 65 on the outer periphery of the visible side case component 12. Further, the tubular member screw flange 57 is provided at a position of the tubular member 50 so as to overlap the case screw flange 14. A screw 3 penetrating through holes formed in the screw flanges 14 and 57 is fastened to the instrument panel 2 of the vehicle, so that the tubular member 50, the case portion 10, and the instrument panel 2 are screwed together. ing.

On the upper side of the vehicle display device 100, a case screw flange 15 projecting to the outer peripheral side is provided at a position deviated from the protruding claw 65 on the outer periphery of the visible side case component 12. The case portion 10 and the instrument panel 2 are screwed together by fastening the screw 4 penetrating the through hole formed in the case screwing flange 15 to the instrument panel 2 of the vehicle.

A method of manufacturing such a vehicle display device 100 will be described with reference to the flowchart of FIG. 15, particularly focusing on a method of attaching the elastic member 70 and the translucent member 60 to the tubular member 50.

First, in the stretching step S10, the ring-shaped elastic member 70 in the natural state is stretched by pulling. Specifically, as shown in FIGS. 16 to 19, a force is applied to the elastic member 70 in the direction from the inner peripheral side to the outer peripheral side (the direction of the arrow in FIG. 16). Here, the elastic member 70 is elastic so that the peripheral length of the elastic member 70 in the extended state is larger than the peripheral length of the visible side opening 50a of the tubular member 50 and is 140% or less of the peripheral length EL in the natural state. It is preferable to extend the member 70.

In the arrangement step S20 after the stretching step S10, the ring-shaped elastic member 70 is attached to the outer peripheral wall surface portion 52 from the outside of the outer peripheral wall surface portion 52 with respect to the tubular member 50 in a state where it is not yet combined with the translucent member 60. Arrange so that it stretches all around. At this time, the elastic member 70 may be temporarily arranged so as to come into contact with the inclined surface 53, but the elastic member 70 may be arranged so as to fit into the concave groove 54.

In the sliding step S30 after the arranging step S20, each protruding claw 65 is locked while sliding the translucent member 60 in which the tip portion 64 of the protruding tubular portion 62 faces the tubular member 50 side. It is inserted into the hole portion 13 to lock the translucent member 60 with respect to the case portion 10. As shown in FIGS. 20 and 21, the tip portion 64 comes into contact with the elastic member 70 together with this slide to start pressing. When the elastic member 70 is temporarily arranged so as to come into contact with the inclined surface 53 in the arrangement step S20, the tip portion 64 pushes the elastic member 70 toward the concave groove 54, so that the elastic member 70 becomes the concave groove 54. And fit into the concave groove 54. In this way, the space between the tubular member 50 and the translucent member 60 is closed by the elastic member 70. The tubular member 50 and the translucent member 60 are combined by the slide step S30.

(Action effect)
The effects of the first embodiment described above will be described again below.

According to the first embodiment, the tubular member 50 formed in a tubular shape and the translucent member 60 integrally formed with the translucent plate portion 61 and the protruding tubular portion 62 are combined with each other.

Further, according to the first embodiment, the tubular member 50 has a regulation flange 55 formed so as to project from the outer peripheral wall surface portion 52 to the outer peripheral side on the non-visual side from the concave groove 54. With such a restricting flange 55, the movement of the elastic member 70 to the anti-visual side is restricted even when the projecting cylinder portion 62 presses the elastic member 70 from the visible side to the non-visual side in the translucent member 60. Therefore, the elastic member 70 is fitted into the concave groove 54 in a state where the contact area is surely secured. Therefore, it becomes difficult for a gap to be formed between the tubular member 50 and the translucent member 60, and it is possible to suppress a situation in which foreign matter invades the information display unit 30.

Further, in the range other than the range R1 in which the concave groove 54 is provided in the circumferential direction, there is a concern that the elastic member 70 may escape to the outer peripheral side while the protruding tubular portion 62 presses the elastic member 70. obtain. However, in the device 100 of the present embodiment, the protruding guide 56 protruding from the regulation flange 55 to the visual recognition side sandwiches the elastic member 70 with the outer peripheral wall surface portion 52. As a result, since the movement of the elastic member 70 to the outer peripheral side is restricted, the contact area of the elastic member 70 with respect to the concave groove 54 and the protruding cylinder portion 62 is secured even in a range other than the range R1 in which the concave groove 54 is provided. A gap is less likely to occur between the tubular member 50 and the translucent member 60. As described above, it is possible to suppress the situation where a foreign substance invades the information display unit 30.

Further, according to the first embodiment, the outer peripheral wall surface portion 52 has an inclined surface 53 that is inclined toward the inner peripheral side toward the viewing side on the viewing side of the concave groove 54. When the elastic member 70 is attached to the tubular member 50, the elastic member 70 can be fitted into the concave groove 54 while sliding the elastic member 70 along the inclined surface 53. Therefore, the information display unit 30 It is possible to easily provide a vehicle display device 100 in which foreign matter is unlikely to enter.

Further, according to the first embodiment, the elastic member 70 is formed in a ring shape stretched over the entire circumference of the outer peripheral wall surface portion 52 of the tubular member 50. In this way, the elastic member 70 can be fitted into the concave groove 54 by utilizing the contraction force of the elastic member 70, so that the effect of suppressing the intrusion of foreign matter into the information display unit 30 can be enhanced. can.

Further, according to the first embodiment, the elastic member 70 is formed in a circular cross section. In this way, when the elastic member 70 is attached to the tubular member 50, the elastic member 70 can be easily fitted into the concave groove 54 while sliding the elastic member 70. Therefore, it is possible to easily provide the vehicle display device 100 in which foreign matter is unlikely to enter the information display unit 30.

(Second Embodiment)
As shown in FIGS. 22 and 23, the second embodiment is a modification of the first embodiment. The second embodiment will be described focusing on the points different from those of the first embodiment.

The concave groove 254 of the second embodiment is provided on the entire circumference of the tubular member 50 in the circumferential direction. Similar to the first embodiment, the regulation flange 55 is provided on the entire circumference, but the protrusion guide is not provided at all.

The elastic member 270 of the second embodiment is formed in a ring shape as in the first embodiment. However, the elastic member 270 is formed in a radial cross section in an X shape in a natural state.
