  However, since the vehicle display device disclosed in Patent Document 1 has an assembly structure in which a display is simply sandwiched between a rectangular dish-shaped holder and a rectangular flat plate-shaped lid member, the usage environment is limited. In a vehicle that is generally severe in terms of vibration, heat, etc., the mounting of the display device to the holder is likely to occur. Further, since the assembly structure is such that the lid member is simply engaged with the protrusion of the holder, assembly backlash is likely to occur due to the positional displacement between the lid member and the holder. Such an assembly backlash invites the generation of noise in the vehicle interior of the vehicle, and hence improvement is desired.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle display device that prevents the generation of noise.

  The invention according to claim 1 is a display device for a vehicle comprising: a display that displays vehicle information on a screen; and a holder that is mounted on the vehicle and holds the display inside. A first contact portion that elastically contacts one of the first side surface portions of the pair of first side surface portions provided on both sides of the front surface portion where the screen is exposed in the first direction in a hexahedral display In the indicator that receives the elastic reaction force from the first contact portion on one of the first side portions, the other first side portion is pressed against the first pressing portion that is pressed, and the display is on the side opposite to the front portion. A second contact portion that elastically contacts the rear surface portion that faces, a second pressing portion that is pressed against the front surface portion of the indicator that receives the elastic reaction force from the second contact portion on the rear surface portion, and a first A pair of second sides provided on both sides of the front portion in the second direction orthogonal to the direction A third contact portion that is inclined with respect to one of the second side surface portions and is obliquely in contact with a corner portion of the display that the one second side surface portion serves as the front surface portion; In the indicator that receives the contact reaction force on one second side surface portion, the other second side surface portion is pressed against the third pressing portion that is pressed, and the indicator toward the third pressing portion side in the second direction, And an insertion opening to be inserted.

  According to the first aspect of the present invention, the hexahedron-shaped display device has a second direction orthogonal to the first direction in which the pair of first side surface portions are provided across the front surface portion where the screen is exposed. The holder is inserted from the insertion opening of the holder toward the third pressing portion of the holder. Under such an inserted state, the indicator is held inside the holder by the joint action of the first to third contact portions and the first to third pressing portions of the holder.

  Specifically, one first side surface portion of the pair of first side surface portions sandwiching the front surface portion in the first direction in the display is subjected to elastic reaction force by elastic contact of the first contact portion of the holder, Thereby, the other first side surface portion is pressed against the first pressing portion of the holder. By the pressing using the elastic reaction force, the indicator can be held by the holder without rattling in the first direction sandwiched between the first contact portion and the first pressing portion.

  Further, the rear surface portion of the display that faces away from the front surface portion is elastically contacted by the second contact portion of the holder and receives an elastic reaction force, whereby the front surface portion is pressed against the second pressing portion of the holder. . By pressing using the elastic reaction force, the display device can be held by the holder without rattling in the front-rear direction sandwiched between the second contact portion and the second pressing portion.

Thus, the curved convex first contact portion that is convex toward one first side surface portion of the display device comes into contact with the one first side surface portion when the display device is inserted from the insertion opening. Therefore, it is easy to elastically deform. According to this, since the insertion resistance of the display can be reduced, it is possible to improve the workability of assembling the display with respect to the holder.

  According to invention of Claim 4, a 2nd contact part is formed in the curved convex surface shape which becomes convex toward a rear surface part. In this manner, the curved convex second contact portion that is convex toward the rear surface portion of the display device is easily elastically deformed by contacting the rear surface portion when the display device is inserted from the insertion opening. According to this, since the insertion resistance of the display can be reduced, it is possible to improve the workability of assembling the display with respect to the holder.

  According to invention of Claim 5, a 1st pressing part is formed in the flat surface shape extended | stretched along a 2nd direction. As described above, the flat surface-shaped first pressing portion extending along the second direction has the first side surface portion to be pressed when the indicator is inserted in the second direction from the insertion opening. The sliding contact can be guided. According to this, since the display device can be correctly slid into the normal position where the first to third contact portions and the first to third pressing portions are subjected to the joint action, the workability of assembling the display device with respect to the holder is improved. Is possible.

  According to the sixth aspect of the present invention, the holder has an inclined portion that is inclined to the opposite side to the third contact portion. In this way, the inclined portion that is inclined to the opposite side of the third contact portion in the holder is the third pressing portion side when the indicator is inserted from the insertion opening portion into the third pressing portion in the second direction. The second side surface portion can be slidably guided to the corner portion of the display unit, which is the front surface portion, and further to the front surface portion. According to this, since the display device can be correctly slid into the normal position where the first to third contact portions and the first to third pressing portions are subjected to the joint action, the workability of assembling the display device with respect to the holder is improved. Is possible.

  According to the seventh aspect of the present invention, the holder has an electrical wiring portion that is electrically connected to the screen and extends from one second side surface portion that forms a corner portion together with the front surface portion through the insertion opening in the display. Thus, the electrical wiring portion of the display that extends from the second side surface portion that forms the corner portion on the third contact portion side together with the front surface portion through the insertion opening is on the side opposite to the third contact portion. When inserting the indicator from the insertion opening to the third pressing portion side, it is difficult to interfere with the holder. According to this, it becomes possible not only to improve the workability of assembling the display with respect to the holder, but also to prevent disconnection of the electrical wiring portion that is electrically connected to the screen in the display.

  According to the eighth aspect of the present invention, the holder is formed by integral molding of each part. Thus, the holder in which each part is integrally formed does not cause a positional shift of each part. Therefore, it is possible to prevent the generation of noise due to the displacement of each part of the holder.

  According to the ninth aspect of the present invention, the display device includes a display panel having a screen and a window portion that opens to expose a screen of the display panel accommodated therein, and the second pushing around the window portion. A panel housing having a hexahedral shape that forms a front portion pressed against the portion together with each first side surface portion, each second side surface portion, and the rear surface portion.

The exposed opening 270 is also opened in a large rectangular hole shape. As a result, the screen 25 of the display 24 is exposed forward through the window portion 290 on the inner peripheral side of the exposure opening 270.

  As shown in FIGS. 2, 3, and 5, in the holder 27, the first side surface portion 29 b on one side of the panel housing 29 (the left side of the screen 25 in this embodiment) and the side portion 27 b facing the first direction X are A first contact portion 271 is provided. The first contact portion 271 is formed in a substantially rectangular piece shape surrounded by a slit 271a penetrating the side portion 27b in a U shape, and starts in the first direction X with the base end 271b connected to the side portion 27b as a starting point. Elastic deformation is possible. The free end 271c opposite to the base end 271b in the first contact portion 271 is formed in a substantially arcuate curved convex surface that is convex toward the first side surface portion 29b. Thereby, the curved contact-shaped free end 271c is brought into contact with the first side surface portion 29b in a state where the first contact portion 271 is elastically deformed.

  Thus, the panel housing 29 in which the first contact portion 271 elastically contacts one of the first side surface portions 29b receives the elastic reaction force from the first contact portion 271 so that the other first as shown in FIG. The one side surface portion 29c is pressed against the inner surface 272 of the side portion 27c facing the first direction X. Here, the inner surface 272 of the side portion 27c is formed in a flat surface shape (see FIG. 5) extending in the second direction Y in the present embodiment, and the flat surface shape to which the first side surface portion 29c is pressed is formed. It functions as the first pressing unit 272. Therefore, the indicator 24 can be held by the holder 27 without rattling in the first direction X in which the panel housing 29 is sandwiched by the first contact portion 271 and the first pressing portion 272. Further, here, the flat surface-shaped first pressing portion 272 is arranged so that when the indicator 24 is inserted into the holder 27 along the second direction Y as indicated by the white arrow in FIG. It also functions as a guide for slidingly guiding the first side surface portion 29c of the housing 29.

  In addition, the 1st contact part 271 of this embodiment is provided in two places along with the 2nd direction Y in the side part 27b, as shown in FIG. Thereby, the force for pressing the first side surface portion 29c against the first pressing portion 272 is obtained as a resultant force of the elastic reaction force of each first contact portion 271 and dispersed in the second direction Y. It has become.

  As shown in FIGS. 2, 3, and 5, the holder 27 further has a substantially semicircular piece-shaped second pressing portion that protrudes toward the inner peripheral side of the exposed opening 270 that penetrates the front portion 27 a. 273 is provided. The second pressing portion 273 forms a protruding portion 273a in a substantially spherical curved convex shape that is convex toward the front surface portion 29a side of the panel housing 29 in the third direction Z.

  In the holder 27, a second contact portion 274 is provided on the rear portion 27 d facing the rear surface portion 29 d of the panel housing 29 in the third direction Z. The second contact portion 274 is formed in a substantially rectangular piece shape surrounded by a slit 274a penetrating the rear portion 27d in a U-shape, and is elastically deformed in the third direction Z starting from the base end 274b connected to the rear portion 27d. It is possible. In the second contact portion 274, the free end 274c opposite to the base end 274b is formed in a substantially arcuate curved convex surface that is convex toward the rear surface portion 29d. Thereby, the curved contact-shaped free end 274c is brought into contact with the rear surface portion 29d while the second contact portion 274 is elastically deformed.

  Thus, the panel housing 29 in which the second contact portion 274 elastically contacts the rear surface portion 29d receives the elastic reaction force from the second contact portion 274, so that the front surface portion 29a is It will be in the state pressed against the projection part 273a of the 2nd pressing part 273 which opposes the 3rd direction Z. FIG. Therefore, the indicator 24 can be held by the holder 27 without rattling in the third direction Z in which the panel housing 29 is sandwiched by the second contact portion 274 and the second pressing portion 273.

  The second pressing portion 273 of the present embodiment protrudes on the inner peripheral side from the exposed opening 270 that penetrates the front portion 27a, but on the inner peripheral side of the window portion 290 that penetrates the front surface portion 29a. It does not protrude. Thereby, since the pressing of the second pressing portion 273 can be avoided against the screen 25 of the display panel 28 exposed from the window portion 290, obstruction of vehicle information display on the screen 25 and surface damage of the screen 25 Is not generated by the second pressing portion 273. In addition, as shown in FIG. 5, the second pressing portion 273 of this embodiment has two places on both sides sandwiching the exposed opening 270 in the first direction X and the exposed opening 270 in the second direction Y. Each of the two sides is provided at one place (upper side in the present embodiment). Thereby, since the pressing area of the front part 29a with respect to the holder 27 is increased and the pressed portions are dispersed around the screen 25 of the display 24, the holding stability of the holder 27 can be improved.

  In addition, as shown in FIGS. 2 and 5, the front portion 27 a of the holder 27 is provided with a protruding portion 275 having a substantially triangular cross section so as to protrude rearward in the third direction Z. The projecting portion 275 forms a third contact portion 275a that is inclined with respect to the second side surface portion 29e on one side of the panel housing 29 (lower side than the screen 25 in this embodiment). The third contact portion 275a is close to the inner surface (third pressing portion described in detail later) 276 of the side portion 27f of the holder 27 facing the other second side surface portion 29f of the panel housing 29 in the second direction Y. That is, it is formed in a flat surface shape that is inclined forward in the third direction Z as it goes upward in the direction Y. Thus, the third contact portion 275a is in contact with the corner portion 29g formed by the second side surface portion 29e of the panel housing 29 with the front surface portion 29a as shown in FIG.

  Thus, the panel housing 29 in which the third contact portion 275a is brought into contact with the corner portion 29g in an inclined manner receives the contact reaction force from the third contact portion 275a, so that the second side surface portion 29f is changed as shown in FIG. It will be in the state pressed against the inner surface 276 of the side part 27f which opposes the 2nd direction Y. Here, the inner surface 276 of the side portion 27f is formed in a flat surface shape extending in the first direction X in the present embodiment, and the flat surface-shaped third pressing portion 276 to which the second side surface portion 29e is pressed. As a function. Therefore, the indicator 24 can be held by the holder 27 without rattling in the second direction Y in which the panel housing 29 is sandwiched by the third contact portion 275a and the third pressing portion 276.

  Further, here, when the indicator 24 is inserted into the holder 27 along the second direction Y (see the white arrow in FIG. 5), as shown in FIG. As a result, the second contact portion 274 is pressed backward in the third direction Z, thereby elastically deforming. Thereby, the corner | angular part 29g of the panel housing 29 will be pressed by the 3rd contact part 275a also by the elastic reaction force which the rear surface part 29d receives from the 2nd contact part 274. Therefore, in the second direction Y of the indicator 24, the rattling action can be enhanced by the wedge action between the elements 275a and 276, and in the third direction Z of the indicator 24, the pressing along the elastic reaction force is performed. Thus, the play suppressing function between the elements 274 and 273 can be enhanced.

  In addition, the protruding portion 275 provided on the front portion 27a of the holder 27 has an inclined portion 275b inclined in the second direction Y, as shown in FIGS. It is formed below the third contact portion 275a. The inclined portion 275b is formed in a flat surface shape that inclines forward in the third direction Z as it goes downward in the second direction Y away from the third pressing portion 276. Thus, when the inclined portion 275b inserts the indicator 24 into the holder 27 along the second direction Y (see the white arrow in FIG. 5), the second side surface portion that is the front side in the insertion direction. 29f functions as a guide for sliding and guiding the corner portion 29h of the panel housing 29 formed with the front surface portion 29a.

  As shown in FIG. 5, in the present embodiment, the protruding portion 275 forming the set of the third contact portion 275a and the inclined portion 275b is outside the window portion 290 of the front surface portion 29a in the first direction X. It is provided so as to be separated from each other. Thereby, the pressing area of the corner portion 29g with respect to the holder 27 is increased and the pressed portions are dispersed to improve the holding stability of the holder 27, and the indicator 24 is placed in the holder 27 along the second direction Y. When being inserted into the screen (see the white arrow in FIG. 5), the inclined portions 275b guide the front surface portion 29a in sliding contact, thereby preventing the surface of the screen 25 from being damaged.

  In addition, as shown in FIGS. 2 and 5, an insertion opening 277 is provided in the holder 27 at a location facing the second side surface 29 e of the panel housing 29 in the second direction Y. The insertion opening 277 has a larger opening than the second side surface portions 29e and 29f which are both side ends in the second direction Y among the six surface portions 29a to 29f of the panel housing 29 having a rectangular parallelepiped shape of the display 24. doing. Thereby, in this embodiment, it becomes possible to insert the indicator 24 into the holder 27 from the insertion opening 277 toward the third pressing portion 276 side in the second direction Y shown in FIG. Yes. Further, as shown in FIG. 2, the FPC 42 extends downward through the second side surface portion 29 e that penetrates the inner peripheral side of the insertion opening 277 and is mounted on the circuit board 44 in the meter case 26. 40 connector portions 40a are electrically connected.

That is, the front portion 27a of the holder 27 and the front surface portion 29a of the display 24 are hidden from the display plate 23 from the driver's seat side and are difficult to see, and only the screen 25 is provided on the inner peripheral side of the display hole 23a. It is visible from the driver's seat side.

  In the present embodiment, with respect to the holder 27 having the above-described configuration, the respective portions 270 to 278 are formed by integral molding. Here, the integral molding of the respective parts 270 to 278 is performed by using a molding die 2700 formed by dividing the mold as shown in FIGS. 7A and 7B, for example, and resin into the cavity 2702 that complements the surface shape of the holder 27. This can be realized by injecting and solidifying the material.

  In order to house the indicator 24 in the holder 27 formed in this way and assemble it to the meter case 26, first, the indicator 24 is inserted into the holder 27 from the insertion opening 277 as indicated by the white arrow shown in FIG. insert. At this time, in this embodiment, until the second side surface portion 29f comes into contact with the third pressing portion 276, the first side surface portion 29c becomes the first pressing portion 272, and the corner portion 29h and the front surface portion 29a are sequentially inclined portions. The display 24 is slid in the second direction Y while being guided by 275b. As the slide is inserted, the contact portions 271 and 274 that come into contact with the surface portions 29b and 29d of the display 24 at the curved convex free ends 271c and 274c can be easily elastically deformed. Becomes smaller. In addition, when the indicator 24 receives the guiding action of the elements 272 and 275b, the normal action of receiving the joint action of the contact parts 271, 274 and 275a and the pressing parts 272, 273 and 276 is obtained. The indicator 24 can be correctly inserted to the position. In addition, the FPC 42 that extends from the second side surface portion 29e of the display 24 through the insertion opening 277 of the holder 27 hardly interferes with the holder 27 during the above-described slide insertion. Therefore, according to the present embodiment, the workability of assembling the display 24 with respect to the holder 27 is improved, and the disconnection between the drive circuit 41 in the display 24 and the control circuit 40 outside the display 24 is performed. It is possible to prevent this.

  Now, with respect to the holder 27 into which the indicator 24 is slid and inserted in this way, the mounting pins 26c and 26d of the meter case 26 are fitted and positioned in the mounting holes 278c and 278d. Thereafter, the tapping screw 279 inserted through the mounting holes 278a and 278b of the holder 27 is screwed into the screw holes 26a and 26b of the meter case 26, whereby the display 24 is connected to the vehicle via the holder 27 and the meter case 26. It can be attached to.

  The indicator 24 mounted on the vehicle as described above is held inside the holder 27 by the joint action of the contact portions 271, 274, 275 a of the holder 27 and the pressing portions 272, 273, 276. It becomes a state. Therefore, with respect to the rectangular parallelepiped-shaped indicator 24, the contact portions 271, 274, 275 a and the pressing portions 272, 273, 276 are interposed between the horizontal direction X, the vertical direction Y, and the front-rear direction Z. Since it can be restrained, it becomes difficult to generate assembly play with respect to the holder 27. Therefore, even if the indicator 24 is a mass-produced product (consumer product) without a dedicated mounting hole or mounting claw for the vehicle, there is a situation in which noise is generated in the vehicle interior of the vehicle due to the assembly play with respect to the holder 27. It can be surely prevented. In addition, since the contact portions 271, 274, 275a and the pressing portions 272, 273, 276 of the holder 27 that produce such operational effects are formed by integral molding, it is possible to prevent the occurrence of noise due to misalignment of these portions. It can be done.

(Other embodiments)
The embodiment of the present invention has been described so far. However, the present invention is not construed as being limited to the embodiment, and can be applied to various embodiments without departing from the gist of the present invention. is there.

  Specifically, the first direction X of the indicator 24 may be set to the vertical direction of the vehicle on the horizontal plane, and the second direction Y of the indicator 24 may be set to the horizontal direction of the vehicle. In addition, the free ends 271c and 274c of the first and second contact portions 271 and 274 may be formed in a substantially triangular cross section such as the protruding portion 275, for example, other than the curved convex surface. Further, the inclined portion 275b may be formed in a curved surface shape as shown in FIG. 8, for example, in addition to the flat surface shape, as long as the inclined portion 275b is inclined to the opposite side to the third contact portion 275a. You may change so that it may not form. Furthermore, the display panel 28 constituting the display 24 may be, for example, an EL (Electro-Luminescence) panel other than the liquid crystal panel described above. The present invention is applied to, for example, a head-up display type vehicle display device that displays a display image of the display 24 in a virtual image, in addition to the vehicle display device 1 including the display 24 that functions as the combination meter 2.
