車両用表示装置Vehicle display device 関連出願の相互参照Cross-reference of related applications
　この出願は、２０１９年４月１８日に日本に出願された特許出願第２０１９－０７９５８７号を基礎としており、基礎の出願の内容を、全体的に、参照により援用している。 This application is based on Patent Application No. 2019-079587 filed in Japan on April 18, 2019, and the contents of the basic application are incorporated by reference as a whole.
　本開示は、座席から所定距離以内に設置されて使用される車両用表示装置に関する。 This disclosure relates to a vehicle display device installed and used within a predetermined distance from a seat.
　従来、ダッシュボードの上面部に立設する態様で使用される車両用表示装置が知られている。また、近年は、このような車両用表示装置として、表示画面の視認性の向上や、デザイン性の向上を目的として、例えば、特許文献１のように、画面を保護するためのカバー部材をガラス製とする構成も種々提案されている。 Conventionally, a vehicle display device used in a manner of standing on the upper surface of a dashboard is known. Further, in recent years, as such a display device for vehicles, for the purpose of improving the visibility and design of the display screen, for example, as in Patent Document 1, a cover member for protecting the screen is made of glass. Various configurations have been proposed.
　尚、特許文献１には、車両用表示装置としてディスプレイ操作性の向上の目的から、タッチパネル機能を備えた構成も開示されている。特許文献１には、ガラス面への衝撃によってガラスが割れる恐れを低減するために、カバー部材を強化ガラスとすると共に、特定の厚みを有するタッチパネルを採用した構成が開示されている。尚、以降では便宜上、ガラス製のカバー部材をカバーガラスと称する。 Note that Patent Document 1 also discloses a configuration as a vehicle display device having a touch panel function for the purpose of improving display operability. Patent Document 1 discloses a configuration in which a cover member is made of tempered glass and a touch panel having a specific thickness is used in order to reduce the risk of the glass breaking due to an impact on the glass surface. Hereinafter, for convenience, the glass cover member will be referred to as a cover glass.
特開２０１８－２２０３４号公報JP-A-2018-2234
　車両用表示装置は、車両の衝突が発生した際に乗員の頭部が衝突しうる範囲（以降、頭部衝突範囲）に配置されることがある。例えば、タッチパネル機能を備えている車両用表示装置は、乗員の操作性を確保するために、頭部衝突範囲として、運転席乗員の手が届く範囲に配置されうる。そのため、カバーガラス等のカバー部材は乗員保護の目的から割れにくいように構成されていることが好ましい。 The vehicle display device may be arranged in a range where the occupant's head can collide when a vehicle collision occurs (hereinafter, the head collision range). For example, the vehicle display device provided with the touch panel function may be arranged within the reach of the driver's seat occupant as the head collision range in order to ensure the operability of the occupant. Therefore, it is preferable that the cover member such as the cover glass is configured so as not to be easily broken for the purpose of protecting the occupants.
　尚、上記の頭部衝突範囲は、車両が使用される地域の法規に基づいて設定されれば良い。例えば日本国内においては、頭部衝突範囲は、日本の国土交通省が示す「道路運送車両の保安基準」の「第２０条　乗車装置」の「別紙２８　インストゥルメントパネルの衝撃吸収の技術基準」等に示される範囲をもとに設定されればよい。 The above head collision range may be set based on the regulations of the area where the vehicle is used. For example, in Japan, the head collision range is defined as "Attachment 28 Technical Standards for Shock Absorption of Instrument Panels" in "Article 20 Riding Equipment" of "Safety Standards for Road Transport Vehicles" indicated by the Ministry of Land, Infrastructure, Transport and Tourism of Japan. It may be set based on the range shown in the above.
　特許文献１に開示の構成によれば、カバーガラスの主面に対して略垂直な方向からの衝撃（換言すれば曲げ破壊）に対する強度の向上は期待できる。しかしながら、特許文献１の車両用表示装置は、カバーガラスの面部に、当該面部に直交する方向から頭部が衝突する場合を想定して構成されている。特許文献１では、カバーガラスのエッジ部へ、斜め上方から頭部が衝突する場合については検討されていない。ここでのカバーガラスのエッジ部とは、カバーガラスの角部を含む端部を指す。 According to the configuration disclosed in Patent Document 1, improvement in strength against impact (in other words, bending fracture) from a direction substantially perpendicular to the main surface of the cover glass can be expected. However, the vehicle display device of Patent Document 1 is configured on the assumption that the head collides with the surface portion of the cover glass from a direction orthogonal to the surface portion. Patent Document 1 does not study the case where the head collides with the edge portion of the cover glass from diagonally above. The edge portion of the cover glass here refers to an end portion including a corner portion of the cover glass.
　また、通常、乗員の頭部は車両用表示装置よりも上方に存在する。そのため、乗員の頭部と車両用表示装置との衝突位置（換言すれば加撃点）は、カバーガラスの面部ではなく、車両用表示装置の上方視認側端部となりうる。車両用表示装置の上方視認側端部への衝撃は、直接的または間接的にカバーガラスの上側エッジ部に作用する。カバーガラスのエッジ部への衝撃は、衝撃の力が小さな面積に集中するため、加撃点がカバーガラスの面部に位置する場合よりも、ガラス破壊に至る恐れが高い。また、エッジ部への衝撃は、衝撃の作用領域が小さいため、曲げ破壊というよりもヘルツ破壊に近いメカニズムで割れることもある。故に、車両用表示装置としては、装置の上方視認側端部に斜め上方から頭部が衝突した場合にも、カバーガラスが割れにくいように構成されていることが好ましい。 Also, the occupant's head is usually located above the vehicle display device. Therefore, the collision position (in other words, the attack point) between the occupant's head and the vehicle display device may be not the surface portion of the cover glass but the upper viewing side end portion of the vehicle display device. The impact on the upper viewing side end of the vehicle display device acts directly or indirectly on the upper edge of the cover glass. Since the impact force on the edge portion of the cover glass is concentrated in a small area, there is a higher risk of glass breakage than when the attack point is located on the surface portion of the cover glass. Further, since the impact on the edge portion has a small impact area, it may be cracked by a mechanism closer to Hertz fracture rather than bending fracture. Therefore, it is preferable that the display device for a vehicle is configured so that the cover glass is not easily broken even when the head collides with the upper viewing side end of the device from diagonally above.
　尚、一般的に表示装置においては、カバーガラスの外周にはフレーム（換言すればベゼル）が配されている。ベゼルの幅を相対的に大きく設定すれば、車両用表示装置の上方視認側端部への衝撃が、直接的または間接的にカバーガラスの上側エッジ部に作用する恐れを低減できる。しかしながら、ベゼル幅は小さいほどが見栄えがよい。そのため、近年はベゼル幅を縮小した車両用表示装置が求められている。尚、アクリル製やポリカーボネート製のカバー部材についても、エッジ部への衝撃に対しては割れやすい性質を有する。つまり、カバー部材がアクリル製やポリカーボネート製である場合にも、エッジ衝撃に対してはカバーガラスと同様の課題を有する。 In general, in a display device, a frame (in other words, a bezel) is arranged on the outer circumference of the cover glass. By setting the width of the bezel relatively large, it is possible to reduce the possibility that the impact on the upper viewing side end portion of the vehicle display device directly or indirectly acts on the upper edge portion of the cover glass. However, the smaller the bezel width, the better the appearance. Therefore, in recent years, there has been a demand for a vehicle display device having a reduced bezel width. The cover member made of acrylic or polycarbonate also has a property of being easily cracked by an impact on the edge portion. That is, even when the cover member is made of acrylic or polycarbonate, it has the same problem as the cover glass against edge impact.
　本開示の目的とするところは、ベゼル幅を抑制しつつ、カバー部材が割れにくい車両用表示装置を提供することにある。 An object of the present disclosure is to provide a vehicle display device in which the cover member is hard to break while suppressing the bezel width.
　本開示は上記目的を達成するために、以下の技術的手段を採用する。 This disclosure employs the following technical means to achieve the above objectives.
　本開示では、車両に搭載され、情報を表示する表示部と、表示部の背面側に配置されたフレームと、表示部を側方から包囲する筒状部材であって、視認側の端部が開口部として形成された包囲部材と、透光性を有し、包囲部材の開口部を塞ぐように表示部の表示面よりも視認側に配置された板状のカバー部材と、を備え、包囲部材の視認側端部は、カバー部材の視認側表面には被さっておらず、表示部、フレーム、包囲部材、およびカバー部材によって表示本体部が形成され、表示本体部の上側が、車両のダッシュボードの上側に飛び出して配置された車両用表示装置において、表示本体部の下側領域の一部が、車両の取付け部に支持されており、フレームの背面側には、車両の衝突時における乗員頭部の衝突に対抗する補強部が設けられ、包囲部材において表示部の上側に位置する部分である上方包囲部の視認側端部である上方視認側端部は、カバー部材の表面よりも視認側に突出するように構成されると共に、乗員頭部の衝突によって、カバー部材のエッジ部側に変形可能に形成されたことを特徴としている。 In the present disclosure, a display unit mounted on a vehicle and displaying information, a frame arranged on the back side of the display unit, and a tubular member surrounding the display unit from the side, the end portion on the viewing side is A surrounding member formed as an opening and a plate-shaped cover member having translucency and arranged on the visual side of the display surface of the display so as to close the opening of the surrounding member are provided and surrounded. The visible end of the member does not cover the visible surface of the cover member, the display body is formed by the display, frame, surrounding member, and cover member, and the upper side of the display body is the dash of the vehicle. In the vehicle display device that is arranged so as to protrude above the board, a part of the lower region of the display main body is supported by the vehicle mounting portion, and the rear side of the frame is the occupant in the event of a vehicle collision. A reinforcing portion is provided to resist a collision of the head, and the upper visible end portion, which is the visible side end portion of the upper surrounding portion, which is a portion located above the display portion in the surrounding member, is more visible than the surface of the cover member. It is characterized in that it is configured to protrude to the side and is deformably formed on the edge side of the cover member due to a collision of the occupant's head.
　上記構成において、包囲部材のうち、表示部の上側に位置する部分の前端部（つまり上方視認側端部）は、カバー部材の表面よりも視認側に突出するように構成されている。故に、乗員の頭部との１次衝突位置は、上方視認側端部となり、車両用表示装置と頭部との衝突による衝撃がカバー部材のエッジ部へ直接印加されることを抑制することができる。 In the above configuration, the front end portion (that is, the upper viewing side end portion) of the portion of the surrounding member located on the upper side of the display portion is configured to project toward the viewing side from the surface of the cover member. Therefore, the primary collision position with the occupant's head is the upper viewing side end, and the impact due to the collision between the vehicle display device and the head can be suppressed from being directly applied to the edge portion of the cover member. it can.
　また、上方視認側端部は、乗員頭部の衝突によってカバー部材のエッジ部側へと変形可能となっている。上方視認側端部が変形することにより、衝突時の衝撃荷重が低減（吸収）されるので、カバー部材への衝撃を低減することができる。 In addition, the upper visible end can be deformed to the edge side of the cover member by the collision of the occupant's head. By deforming the upper viewing side end portion, the impact load at the time of collision is reduced (absorbed), so that the impact on the cover member can be reduced.
　また、表示本体部の下側領域の一部が車両の取付け部に支持されているので、乗員頭部の衝突を受けると、表示本体部の上部側は、取付け部を起点にして、衝撃の方向に円弧を描くように変位する。このとき、フレームの背面側には、車両の衝突時における乗員頭部の衝突に対抗する補強部が設けられているので、表示本体部は、折れ曲がるように破断することなく、変位可能となって衝撃力を受け流し、乗員に対する衝撃を緩和することが可能である。 Further, since a part of the lower region of the display main body is supported by the vehicle mounting portion, when the occupant's head collides, the upper side of the display main body starts from the mounting portion and receives an impact. Displace in a circular arc in the direction. At this time, since a reinforcing portion is provided on the back side of the frame to counter the collision of the occupant's head in the event of a vehicle collision, the display main body portion can be displaced without breaking so as to bend. It is possible to displace the impact force and reduce the impact on the occupants.
　そして、表示本体部が変位することによって、乗員頭部による衝突の位置（２次衝突位置）は、上方視認側端部から下側にずれるが、上記のように、上方視認側端部の変形、および表示本体部の変位により、衝突荷重がすでに低減（緩和）されていることから、カバー部材が割れに至るおそれは回避される。 Then, due to the displacement of the display main body, the position of the collision by the occupant's head (secondary collision position) shifts downward from the upper viewing side end, but as described above, the deformation of the upper viewing side end is deformed. Since the collision load has already been reduced (relaxed) due to the displacement of the display main body, the possibility that the cover member will crack is avoided.
　以上のように、車両用表示装置への頭部衝突によってカバー部材が割れるおそれを低減することができる。 As described above, it is possible to reduce the risk of the cover member breaking due to a head collision with the vehicle display device.
　尚、上記構成においては、包囲部材の視認側端部がベゼルに相当する。上記の作用効果は、上方視認側端部をカバー部材の表面よりも視認側に突出させて、変形可能とすることによって得られる。そのため、包囲部材の視認側端部（つまりベゼル）の幅を増大させる必要性は小さい。つまり、上記の構成によれば、ベゼル幅を抑制しつつ、カバー部材が割れにくい車両用表示装置を提供することができる。 In the above configuration, the visible end of the surrounding member corresponds to the bezel. The above-mentioned action and effect can be obtained by projecting the upper viewing side end portion toward the viewing side from the surface of the cover member so as to be deformable. Therefore, there is little need to increase the width of the visible end (that is, the bezel) of the surrounding member. That is, according to the above configuration, it is possible to provide a vehicle display device in which the cover member is hard to break while suppressing the bezel width.

The vehicle display device 100 of the first embodiment is installed on the dashboard 200 (instrument panel design member 201, instrument panel internal member 202) of the vehicle, and is configured as a device for displaying various information. More specifically, the vehicle display device 100 is arranged in a region located at the center in the vehicle width direction on the upper surface of the dashboard 200 with the display surface of the display 1 facing the rear of the vehicle. The direction in which information is displayed on the vehicle display device 100 (occupant side) is referred to as a visual recognition side. The visible side corresponds to the front side for the vehicle display device 100. Further, the direction opposite to the visual recognition side will be referred to as the back side. Although the driver's seat is provided on the right side of the vehicle in FIG. 1, the vehicle provided with the vehicle display device 100 may be a vehicle having a driver's seat on the left side. Further, the vehicle display device 100 may be used in a fully autonomous vehicle that does not have a driver's seat.
　尚、車両用表示装置１００には、予め上下方向と左右方向とが設定されている。車両用表示装置１００は、上下方向が車両の上下方向に略平行となるように取り付けられている。また、車両用表示装置１００は、左右方向が車両の左右方向（換言すれば車幅方向）に略平行となるように取り付けられている。略平行とは、完全に平行な状態に限らず、完全に平行な状態から３０°程度傾いている状態を含む。つまり、車両用表示装置１００は、車両水平面に対して運転席に着座している乗員がディスプレイ１の表示画面を違和感なく認識できる程度に傾いた姿勢で、取り付けられていても良い。車両水平面とは、車両の高さ方向に垂直な平面を指す。 The vehicle display device 100 is preset with a vertical direction and a horizontal direction. The vehicle display device 100 is attached so that the vertical direction is substantially parallel to the vertical direction of the vehicle. Further, the vehicle display device 100 is attached so that the left-right direction is substantially parallel to the left-right direction of the vehicle (in other words, the vehicle width direction). The substantially parallel state is not limited to a completely parallel state, but includes a state in which the state is tilted by about 30 ° from the completely parallel state. That is, the vehicle display device 100 may be mounted in an inclined posture so that the occupant seated in the driver's seat can recognize the display screen of the display 1 with respect to the horizontal surface of the vehicle without discomfort. The vehicle horizontal plane refers to a plane perpendicular to the height direction of the vehicle.
　図２に示すように、車両用表示装置１００は、後述する表示本体部１０１の上側が車両のダッシュボード２００の上側に飛び出して配置されている。この搭載形態は、いわゆる、オンダッシュ搭載と呼ばれている。そして、表示本体部１０１の下側領域の一部が、車両のインパネ意匠部材２０１の内側に形成されたインパネ内部部材２０２に支持されている。具体的には、表示本体部１０１の下側領域（ここでは、後述する描画ユニット２の下側面）には、下側に延びる取付けステー２１が形成されており、この取付けステー２１の先端側が、ボルト２２等の締結部材によってインパネ内部部材２０２に固定されている。インパネ内部部材２０２は、本開示の取付け部に対応する。 As shown in FIG. 2, the vehicle display device 100 is arranged so that the upper side of the display main body 101, which will be described later, protrudes above the dashboard 200 of the vehicle. This mounting form is so-called on-dash mounting. A part of the lower region of the display main body 101 is supported by the instrument panel internal member 202 formed inside the instrument panel design member 201 of the vehicle. Specifically, a mounting stay 21 extending downward is formed in the lower region of the display main body 101 (here, the lower side surface of the drawing unit 2 described later), and the tip end side of the mounting stay 21 is formed. It is fixed to the instrument panel internal member 202 by a fastening member such as a bolt 22. The instrument panel internal member 202 corresponds to the mounting portion of the present disclosure.
　尚、車両用表示装置１００の固定形態として、例えば、表示本体部１０１の下側に取付けステーを設けて、インパネ意匠部材２０１に固定する、あるいは、表示本体部１０１の下側に突状の結合部を設けて、インパネ意匠部材２０１に形成された差込み孔等に差し込むことで固定する等、としてもよい。 As a fixed form of the vehicle display device 100, for example, a mounting stay is provided on the lower side of the display main body 101 and fixed to the instrument panel design member 201, or a protruding connection is made on the lower side of the display main body 101.

Further, the visible side end of the upper surrounding portion corresponds to the upper visible side end. Hereinafter, among the configurations of the vehicle display device 100, the configuration near the upper surface portion 120A will be mainly described. For example, the “visually visible end portion of the surrounding member 5” below refers to the visible side end portion of the surrounding member 5 located above the display 1 (that is, the upper surface portion 120A). Of course, the following description can be applied to parts other than the upper surface portion 120A. The side surface portion of a certain member refers to a surface of the member facing a direction substantially orthogonal to the viewing direction. Further, the visible side end portion of a certain member refers to the frontmost end portion (that is, the front end portion) of the member.
　車両用表示装置１００は、図４、図５に示すように、ディスプレイ１、描画ユニット２、フレーム３、背面ケース４、包囲部材５、およびカバー部材６等が組み合わされて実現されている。ここでは、ディスプレイ１、フレーム３、包囲部材５、およびカバー部材６の組合せが本開示の表示本体部１０１に対応する。 As shown in FIGS. 4 and 5, the vehicle display device 100 is realized by combining a display 1, a drawing unit 2, a frame 3, a rear case 4, a surrounding member 5, a cover member 6, and the like.

　液晶パネル１１は、光源フレーム１３を介してバックライト１２の視認側に固定されている。光源フレーム１３と液晶パネル１１とは、接着剤１４によって接着されている。接着剤１４としては、弾性接着剤や弾性両面テープ等が使用される。尚、弾性両面テープとは、不織布やスポンジ等の両面に粘着剤が塗布された、弾性（換言すればクッション性、伸縮性）を有する両面テープを指す。弾性両面テープとしては、例えばアクリルフォームを用いた両面テープ等がある。 The liquid crystal panel 11 is fixed to the visible side of the backlight 12 via the light source frame 13. The light source frame 13 and the liquid crystal panel 11 are adhered to each other by an adhesive 14. As the adhesive 14, an elastic adhesive, an elastic double-sided tape, or the like is used. The elastic double-sided tape refers to a double-sided tape having elasticity (in other words, cushioning property and elasticity) in which an adhesive is applied to both sides of a non-woven fabric, sponge, or the like. Examples of the elastic double-sided tape include double-sided tape using acrylic foam.
　描画ユニット２は、上下方向に厚みを有する扁平な箱状を成して、表示本体部１０１の背面側で下側となる領域に配置されて、後述する背面ケース４の下側開口部、およびフレーム３を介して、ディスプレイ１に接続されている。描画ユニット２は、ディスプレイ１の表示状態を制御する制御部となっている。描画ユニット２は、表示用の元画像データ、および乗員による操作状態等に応じて、バックライト１２の発光状態、および液晶パネル１１における複数の液晶画素の透光状態を調整することで、ディスプレイ１の画像表示（画像の形成、および画像の色、輝度の設定等）を制御するようになっている。描画ユニット２は、上記で説明したように、取付けステー２１、ボルト２２によってインパネ内部部材２０２に固定されている。 The drawing unit 2 has a flat box shape having a thickness in the vertical direction, is arranged in an area on the lower side on the back side of the display main body 101, and has a lower opening of the back case 4 described later and a lower opening. It is connected to the display 1 via the frame 3. The drawing unit 2 is a control unit that controls the display state of the display 1. The drawing unit 2 adjusts the light emitting state of the backlight 12 and the translucent state of a plurality of liquid crystal pixels in the liquid crystal panel 11 according to the original image data for display and the operation state by the occupant, thereby adjusting the display 1 The image display (image formation, image color, brightness setting, etc.) is controlled.

The frame 3 is, for example, a metal molded product (die-cast product) formed of a metal material such as aluminum, magnesium, stainless steel, or a steel plate. The frame 3 has a main body portion 31, an extension portion 32, and a reinforcing rib 33, which are integrally formed. The frame 3 is joined to at least a part of the area surrounding the upper side of the display 1 in the surrounding member 5 described later.
　本体部３１は、バックライト１２の背面側に配置される板状の部材となっている。延設部３２は、本体部３１の周囲から、視認側に折り曲げられて延設された板状の部位となっている。延設部３２は、後述する包囲部材５の延設部５４に接合されている。また、補強リブ３３は、本体部３１の背面側に設けられており、車両の衝突時における乗員頭部の表示本体部１０１への衝突に対抗するための補強部となっている。具体的には、補強リブ３３は、本体部３１から背面側に突出する複数の板状部材として形成されている。複数の板状部材は、板厚方向が左右方向となっており、上側から下側に向けて突出量が順次大きくなって、側方から見た形状が三角形となるように形成されており、これら板状部材が車両の左右方向に並ぶように配置されている。 The main body 31 is a plate-shaped member arranged on the back side of the backlight 12. The extension portion 32 is a plate-shaped portion that is bent and extended toward the viewing side from the periphery of the main body portion 31. The extension portion 32 is joined to the extension portion 54 of the enclosing member 5, which will be described later. Further, the reinforcing rib 33 is provided on the back side of the main body portion 31, and is a reinforcing portion for countering a collision of the occupant's head with the display main body portion 101 at the time of a vehicle collision. Specifically, the reinforcing rib 33 is formed as a plurality of plate-shaped members protruding from the main body 31 to the back surface side. The plurality of plate-shaped members are formed so that the plate thickness direction is the left-right direction, the amount of protrusion gradually increases from the upper side to the lower side, and the shape seen from the side becomes a triangle. These plate-shaped members are arranged so as to be arranged in the left-right direction of the vehicle.
　上記のフレーム３は、例えば、スナップフィット機構によってディスプレイ１に固定されている。尚、これらの部材が組み合わさった状態を維持するための方法（以降、固定方法）はこれに限らない。フレーム３とディスプレイ１は、ネジ止めや、溶着等によって結合されていてもよい。 The above frame 3 is fixed to the display 1 by, for example, a snap-fit mechanism. The method for maintaining the combined state of these members (hereinafter, the fixing method) is not limited to this. The frame 3 and the display 1 may be connected by screwing, welding, or the like.
　背面ケース４は、フレーム３を背面側から覆うための部材であり、下側領域には、描画ユニット２の視認側となる端部を挿入させるための下側開口部が形成されている。背面ケース４は、例えば、ポリカーボネートなどの合成樹脂を用いて遮光性を有するように構成されている。背面ケース４は、フレーム３を収容するための必要十分な大きさに形成されている。背面ケース４は、下側領域から上側領域に向けて徐々に視認側に向かって傾斜するように形成されている。 The back case 4 is a member for covering the frame 3 from the back side, and a lower opening for inserting an end portion of the drawing unit 2 on the visual side is formed in the lower region. The back case 4 is configured to have a light-shielding property by using, for example, a synthetic resin such as polycarbonate. The back case 4 is formed to have a size necessary and sufficient for accommodating the frame 3. The back case 4 is formed so as to gradually incline toward the viewing side from the lower region to the upper region.
　背面ケース４の外周部分には、包囲部材５の背面側に設けられている嵌合爪と嵌合するための嵌合溝が設けられている。嵌合溝は嵌合爪と対応する位置に設けられていればよく、その数や形成箇所は適宜設計されれば良い。嵌合溝は全周にわたって形成されていてもよい。防水性向上の観点から、背面ケース４と包囲部材５の接続部分にはＯリングなどが配されていても良い。つまり、背面ケース４と包囲部材５の接続部分には多様な防水、耐塵構造を適用することができる。背面ケース４と包囲部材５とは、ネジ止めや、溶着、弾性接着剤によって固定されていてもよい。 The outer peripheral portion of the back case 4 is provided with a fitting groove for fitting with the fitting claw provided on the back side of the surrounding member 5. The fitting grooves may be provided at positions corresponding to the fitting claws, and the number and formation locations thereof may be appropriately designed. The fitting groove may be formed over the entire circumference. From the viewpoint of improving waterproofness, an O-ring or the like may be arranged at the connecting portion between the back case 4 and the surrounding member 5. That is, various waterproof and dustproof structures can be applied to the connecting portion between the back case 4 and the surrounding member 5. The back case 4 and the surrounding member 5 may be fixed by screwing, welding, or an elastic adhesive.
　包囲部材５は、ディスプレイ１を含むフレーム３を側方から全周に亘って包囲する筒状部材である。ここでの側方とは、ディスプレイ１の厚み方向に直交する方向を指す。包囲部材５の視認側の端部、および、背面側の端部は開口部として形成されている。ここでの筒状には、断面が円／楕円形状となる円筒形状に限らず、断面が矩形状の角筒形状なども含まれる。包囲部材５は、例えば、ポリカーボネート（ＰＣ）樹脂等の樹脂材料を用いた部材（樹脂成形品）となっており、遮光性を有するように構成されている。 The surrounding member 5 is a tubular member that surrounds the frame 3 including the display 1 from the side over the entire circumference. The side here refers to a direction orthogonal to the thickness direction of the display 1. The visible end and the back end of the enclosing member 5 are formed as openings. The cylindrical shape here is not limited to a cylindrical shape having a circular / elliptical cross section, but also includes a square tubular shape having a rectangular cross section. The surrounding member 5 is, for example, a member (resin molded product) using a resin material such as polycarbonate (PC) resin, and is configured to have a light-shielding property.
　包囲部材５は、周壁部５１、カバー受け部５２、ベゼル部５３、および延設部５４等を一体的に備えている。周壁部５１、カバー受け部５２、ベゼル部５３、および延設部５４といった構成は、何れも包囲部材５の一部を指すものである。周壁部５１、カバー受け部５２、ベゼル部５３、および延設部５４といった構成は、物理的には（換言すれば実体としては）一体的に連続的につながっている。 The surrounding member 5 integrally includes a peripheral wall portion 51, a cover receiving portion 52, a bezel portion 53, an extension portion 54, and the like. The configurations such as the peripheral wall portion 51, the cover receiving portion 52, the bezel portion 53, and the extension portion 54 all refer to a part of the surrounding member 5. The configurations such as the peripheral wall portion 51, the cover receiving portion 52, the bezel portion 53, and the extension portion 54 are physically (in other words, as a substance) integrally and continuously connected.
　周壁部５１は、背面ケース４と嵌合されることによって、ディスプレイ１、およびフレーム３等を外周側から包囲する部位となっている。周壁部５１は、包囲部材５の本体部分に相当する。周壁部５１の背面側端部には、背面ケース４の外周部分に設けられている嵌合溝と係合するための嵌合爪が設けられている。周壁部５１は、別の観点によれば、後述するカバー受け部５２から視認側に向かって延設されている筒状の構成に相当する。 The peripheral wall portion 51 is fitted with the back case 4 to form a portion that surrounds the display 1, the frame 3, and the like from the outer peripheral side. The peripheral wall portion 51 corresponds to the main body portion of the surrounding member 5. A fitting claw for engaging with a fitting groove provided on the outer peripheral portion of the back case 4 is provided at the rear end of the peripheral wall portion 51. From another viewpoint, the peripheral wall portion 51 corresponds to a tubular configuration extending from the cover receiving portion 52, which will be described later, toward the visual recognition side.
　カバー受け部５２は、周壁部５１の視認側端部で、径方向内側（ディスプレイ１の表示面の中心側）に張り出すように形成されており、後述するカバー部材６の縁部を背面側から支持するための構成となっている。カバー受け部５２は、周壁部５１の内側を概ね一周するように連設されている。カバー受け部５２は、ディスプレイ１の表示面と平行となるように、平坦に構成されており、視認側の面は、受け面５２１となっている。 The cover receiving portion 52 is a visible end portion of the peripheral wall portion 51 and is formed so as to project inward in the radial direction (center side of the display surface of the display 1), and the edge portion of the cover member 6 described later is on the back side. It is configured to support from. The cover receiving portion 52 is continuously provided so as to substantially go around the inside of the peripheral wall portion 51. The cover receiving portion 52 is configured to be flat so as to be parallel to the display surface of the display 1, and the surface on the viewing side is the receiving surface 521.
　ベゼル部５３は、包囲部材５において周壁部５１から延設されて、カバー受け部５２よりも視認側に位置する部位となっている。ベゼル部５３は、車両の衝突時における乗員頭部の衝突の際に、後述するカバー部材６のエッジ部６１側に変形可能となっている。ベゼル部５３は、本開示の上方視認側端部に対応する。ベゼル部５３は、後述するカバー部材６の縁部（換言すればエッジ部６１）を囲むように、カバー受け部５２の縁部に立設されている。ベゼル部５３は、カバー部材６の視認側表面に被さらないように、受け面５２１に対して略垂直に立設されている。つまり、包囲部材５（ベゼル部５３）は、カバー部材６の視認側表面に被さらないように構成されている。 The bezel portion 53 extends from the peripheral wall portion 51 in the surrounding member 5 and is located on the visual side of the cover receiving portion 52. The bezel portion 53 can be deformed to the edge portion 61 side of the cover member 6, which will be described later, when the occupant's head collides with the vehicle. The bezel portion 53 corresponds to the upper viewing side end portion of the present disclosure. The bezel portion 53 is erected on the edge portion of the cover receiving portion 52 so as to surround the edge portion (in other words, the edge portion 61) of the cover member 6 described later. The bezel portion 53 is erected substantially perpendicular to the receiving surface 521 so as not to cover the visible surface of the cover member 6. That is, the surrounding member 5 (bezel portion 53) is configured so as not to cover the visible surface of the cover member 6.
　ベゼル部５３の厚みは、例えば、１．５ｍｍ以上（２．５ｍｍ程度）に設定されている。尚、ベゼル部５３の外縁部は面取りされている。例えばベゼル部５３の最奥部から先端部に向かって徐々に幅が小さくなるように形成されている。ベゼル部５３の厚みは、カバー部材６の周囲に見える包囲部材５の幅に相当する。また、ベゼル部５３の厚みは、上方視認側端部の上下方向における幅に相当する。ベゼル部５３の厚みは、１０ｍｍ以下に設定されていればよい。また、ベゼル部５３の厚みは、デザイン性の観点からは、大きくとも５．０ｍｍ以下に設定されていることが好ましい。ベゼル部５３の厚みは、デザイン性の観点から３．０ｍｍ以下に設定されていることがより一層好ましい。 The thickness of the bezel portion 53 is set to, for example, 1.5 mm or more (about 2.5 mm). The outer edge of the bezel portion 53 is chamfered. For example, the bezel portion 53 is formed so that the width gradually decreases from the innermost portion toward the tip portion. The thickness of the bezel portion 53 corresponds to the width of the surrounding member 5 that can be seen around the cover member 6. Further, the thickness of the bezel portion 53 corresponds to the width of the upper viewing side end portion in the vertical direction. The thickness of the bezel portion 53 may be set to 10 mm or less. Further, the thickness of the bezel portion 53 is preferably set to 5.0 mm or less at the maximum from the viewpoint of design. It is even more preferable that the thickness of the bezel portion 53 is set to 3.0 mm or less from the viewpoint of design.
　また、ベゼル部５３の受け面５２１に対する高さ（視認方向の長さ）は、カバー部材６の厚みと、弾性接着部材７の厚みを加えた値に、０．５ｍｍ程度の尤度を与えた値に設定されている。本実施形態では、ベゼル部５３の受け面５２１に対する高さは、２．４ｍｍ程度に設定されている。つまり、ベゼル部５３の先端部は、カバー部材６の視認側表面から０．５ｍｍ程度、突出するように構成されている。 Further, the height (length in the visual viewing direction) of the bezel portion 53 with respect to the receiving surface 521 is a value obtained by adding the thickness of the cover member 6 and the thickness of the elastic adhesive member 7 with a likelihood of about 0.5 mm. It is set to a value. In the present embodiment, the height of the bezel portion 53 with respect to the receiving surface 521 is set to about 2.4 mm. That is, the tip portion of the bezel portion 53 is configured to protrude by about 0.5 mm from the visible side surface of the cover member 6.
　尚、カバー部材６に対するベゼル部５３の突出量は非常に小さいため、ベゼル部５３は見返し板（換言すればフード）としては機能しない。また、カバー部材６に対するベゼル部５３の突出量は、小さいため、ユーザからするとカバー部材６に対してベゼル部５３が突出しているといった印象は与えにくい。つまり、ベゼル部５３とカバー部材６とが略シームレスに接続する外観形状を提供することができる。尚、ベゼル部５３は、カバー部材６に対するベゼル部５３の突出量は、０．１ｍｍ以上、２．０ｍｍ以下となるように構成されていれば良い。ベゼル部５３は、カバー部材６の表面よりも突出するように構成されていればよく、その突出量は０．３ｍｍ以上であることがより好ましい。また、デザイン性の観点においては、ベゼル部５３は、カバー部材６に対するベゼル部５３の突出量が１．０ｍｍ以下となるように構成されていることが好ましい。 Since the amount of protrusion of the bezel portion 53 with respect to the cover member 6 is very small, the bezel portion 53 does not function as a back plate (in other words, a hood). Further, since the amount of protrusion of the bezel portion 53 with respect to the cover member 6 is small, it is difficult for the user to give the impression that the bezel portion 53 protrudes with respect to the cover member 6. That is, it is possible to provide an external shape in which the bezel portion 53 and the cover member 6 are connected substantially seamlessly. The bezel portion 53 may be configured such that the protrusion amount of the bezel portion 53 with respect to the cover member 6 is 0.1 mm or more and 2.0 mm or less. The bezel portion 53 may be configured to protrude from the surface of the cover member 6, and the amount of protrusion thereof is more preferably 0.3 mm or more. Further, from the viewpoint of design, the bezel portion 53 is preferably configured so that the amount of protrusion of the bezel portion 53 with respect to the cover member 6 is 1.0 mm or less.
　延設部５４は、カバー受け部５２における周壁部５１側の端部と先端部との途中位置から、周壁部５１と平行に背面側に延びる板状の部位となっている。周壁部５１と延設部５４との間にフレーム３の延設部３２が入り込んでおり、延設部３２の下側面と、延設部５４の上側面とが接合されている。 The extended portion 54 is a plate-shaped portion extending from the intermediate position between the end portion and the tip portion of the cover receiving portion 52 on the peripheral wall portion 51 side to the back surface side in parallel with the peripheral wall portion 51. The extension portion 32 of the frame 3 is inserted between the peripheral wall portion 51 and the extension portion 54, and the lower side surface of the extension portion 32 and the upper side surface of the extension portion 54 are joined.
　カバー部材６は、ディスプレイ１の表示面を保護するための構成である。カバー部材６は、透明な板状部材である。カバー部材６は、ガラスを用いて構成されている。ここでのガラスには強化ガラスも含まれる。尚、カバー部材６は、透光性の観点からガラス製であることが好ましいが、他の態様としてカバー部材６は、アクリル製やポリカーボネート製など、樹脂製であってもよい。カバー部材６の厚みは、１．５ｍｍ程度に設定されている。尚、カバー部材６の厚みは、適宜変更可能である。カバー部材６の厚みは、０．２５ｍｍや、０．５ｍｍ、１．０ｍｍ、２．０ｍｍなどであっても良い。 The cover member 6 has a configuration for protecting the display surface of the display 1. The cover member 6 is a transparent plate-shaped member. The cover member 6 is made of glass. The glass here also includes tempered glass. The cover member 6 is preferably made of glass from the viewpoint of translucency, but as another embodiment, the cover member 6 may be made of resin such as acrylic or polycarbonate. The thickness of the cover member 6 is set to about 1.5 mm. The thickness of the cover member 6 can be changed as appropriate. The thickness of the cover member 6 may be 0.25 mm, 0.5 mm, 1.0 mm, 2.0 mm, or the like.
　カバー部材６は、包囲部材５のベゼル部５３の内側寸法と略同一に形成されている。具体的には、カバー部材６は、包囲部材５に取り付けられた状態において、カバー部材６（カバー部材６端部のエッジ部６１）と、ベゼル部５３との間に０．５ｍｍ程度の隙間が生じる大きさに（つまり微小量だけ小さめに）形成されている。このようにベゼル部５３とカバー部材６との隙間を０．５ｍｍ程度に設定した構成によれば、両者の線膨張係数の差に起因して、ベゼル部５３とカバー部材６とが接触し、カバー部材６に応力がかかる恐れを低減することができる。また、車両用表示装置１００の上端部への衝撃に伴ってベゼル部５３とカバー部材６とが接触し、カバー部材６に応力がかかるおそれを低減できる。尚、ベゼル部５３とカバー部材６との隙間は、０．１ｍｍ以上、２．０ｍｍ以下に設定されていれば良い。ベゼル部５３とカバー部材６との隙間の製造上の目標値（設計値）は、０．２ｍｍや、０．８ｍｍ、１．０ｍｍ、１．５ｍｍなどであってもよい。 The cover member 6 is formed to be substantially the same as the inner dimension of the bezel portion 53 of the surrounding member 5. Specifically, when the cover member 6 is attached to the surrounding member 5, there is a gap of about 0.5 mm between the cover member 6 (edge portion 61 at the end of the cover member 6) and the bezel portion 53. It is formed to the size that occurs (that is, smaller by a small amount). According to the configuration in which the gap between the bezel portion 53 and the cover member 6 is set to about 0.5 mm in this way, the bezel portion 53 and the cover member 6 come into contact with each other due to the difference in the coefficient of linear expansion between the two. The risk of stress being applied to the cover member 6 can be reduced. Further, it is possible to reduce the possibility that the bezel portion 53 and the cover member 6 come into contact with each other due to the impact on the upper end portion of the vehicle display device 100 and stress is applied to the cover member 6. The gap between the bezel portion 53 and the cover member 6 may be set to 0.1 mm or more and 2.0 mm or less. The manufacturing target value (design value) of the gap between the bezel portion 53 and the cover member 6 may be 0.2 mm, 0.8 mm, 1.0 mm, 1.5 mm, or the like.
　カバー部材６は、包囲部材５の視認側の開口部を塞ぐように、包囲部材５の受け面５２１に、所定の弾性接着部材７を用いて接着されている。弾性接着部材７は、弾性接着剤、または弾性両面テープを用いて実現されている。弾性接着部材７の厚みは０．４ｍｍ程度に設定されている。カバー部材６が弾性接着部材７によって包囲部材５に固定されることにより、車両用表示装置１００の上端部への衝撃に伴う受け面５２１の変位が、カバー部材６へ曲げ応力として作用することを和らげることができる。また、カバー部材６と包囲部材５の線膨張係数の差によって発生する応力（いわゆる熱応力）を弾性接着部材７で吸収できる。そのため、包囲部材５の熱変形に起因してカバー部材６が割れることを抑制することができる。尚、ここでの線膨張係数とは、温度の上昇に対応して物体の長さが変化する割合を指す。 The cover member 6 is adhered to the receiving surface 521 of the enclosing member 5 by using a predetermined elastic adhesive member 7 so as to close the opening on the visual side of the enclosing member 5. The elastic adhesive member 7 is realized by using an elastic adhesive or an elastic double-sided tape. The thickness of the elastic adhesive member 7 is set to about 0.4 mm. By fixing the cover member 6 to the surrounding member 5 by the elastic adhesive member 7, the displacement of the receiving surface 521 due to the impact on the upper end portion of the vehicle display device 100 acts as a bending stress on the cover member 6. Can be relieved. Further, the elastic adhesive member 7 can absorb the stress (so-called thermal stress) generated by the difference in the linear expansion coefficient between the cover member 6 and the surrounding member 5. Therefore, it is possible to prevent the cover member 6 from cracking due to thermal deformation of the surrounding member 5. The coefficient of linear expansion here refers to the rate at which the length of the object changes in response to an increase in temperature.
　また、カバー部材６は、ディスプレイ１（液晶パネル１１）の表示面と、透光性を有する所定の樹脂材料（以降、オプティカルボンディング材）を用いて接着されている。つまり、カバー部材６は、ディスプレイ１とオプティカルボンディングされている。便宜上、カバー部材６と、ディスプレイ１との隙間を埋める樹脂層を、光学接着層８と称する。オプティカルボンディング材としては、無色透明であって弾性を有する樹脂であればよく、多様な樹脂材料を採用可能である。オプティカルボンディング材としては、アクリル系、シリコン系、ウレタン系の樹脂（いわゆるＯＣＲ：Ｏｐｔｉｃａｌ　Ｃｌｅａｒ　Ｒｅｓｉｎ）が好適である。 Further, the cover member 6 is adhered to the display surface of the display 1 (liquid crystal panel 11) by using a predetermined resin material having translucency (hereinafter referred to as an opticarboning material). That is, the cover member 6 is opti-carboned with the display 1. For convenience, the resin layer that fills the gap between the cover member 6 and the display 1 is referred to as an optical adhesive layer 8. As the opticarbonating material, any resin that is colorless and transparent and has elasticity may be used, and various resin materials can be adopted. As the optical carboning material, acrylic, silicon, or urethane resins (so-called OCR: Optical Clear Resin) are suitable.
　尚、光学接着層８は、シート状のＯＣＡ（Ｏｐｔｉｃａｌ　Ｃｌｅａｒ　Ａｄｈｅｓｉｖｅ）を用いて実現されていても良い。ディスプレイ１とカバー部材６との間に光学接着層８を設けた構成によれば、光の反射を抑制し、視認性を向上させることができる。カバー部材６および光学接着層８は、その透光性により、ディスプレイ１の表示を乗員から視認可能に透過する。尚、光学接着層８は任意の要素であって、省略可能である。 The optical adhesive layer 8 may be realized by using a sheet-shaped OCA (Optical Clear Adhesive). According to the configuration in which the optical adhesive layer 8 is provided between the display 1 and the cover member 6, it is possible to suppress the reflection of light and improve the visibility. Due to its translucency, the cover member 6 and the optical adhesive layer 8 visibly transmit the display of the display 1 to the occupants. The optical adhesive layer 8 is an arbitrary element and can be omitted.
　上記のように、弾性接着部材７、および光学接着層８が設けられることで、カバー部材６とディスプレイ１との隙間を埋めて、カバー部材６の背面側を受ける面積を拡大することで、衝突時のカバー部材６にかかる応力を相対的に小さくすることができる。尚、光学接着層８は、必要に応じて設ければよく、廃止しても構わない。 As described above, by providing the elastic adhesive member 7 and the optical adhesive layer 8, the gap between the cover member 6 and the display 1 is filled, and the area for receiving the back surface side of the cover member 6 is expanded to cause a collision. The stress applied to the cover member 6 at the time can be made relatively small. The optical adhesive layer 8 may be provided as needed and may be abolished.
　本実施形態の車両用表示装置１００は、以上のようになっており、以下、その作動および作用効果について説明する。 The vehicle display device 100 of the present embodiment is as described above, and its operation and operation / effect will be described below.
　車両用表示装置１００は、乗員の頭部よりも下方であって、車両の前端衝突が発生した際に、その衝撃により乗員の頭部が衝突しうる範囲（以降、頭部衝突範囲）に配置されうる。車両用表示装置１００が頭部衝突範囲に取り付けられている場合、車両衝突の衝撃によって乗員の頭部は、図６に示すように、車両用表示装置１００の上端部へ斜め上方から衝突しうる。図６は、車両用表示装置１００をダッシュボード２００の上側に飛び出すように載置した状態において、乗員の頭部を模した、直径１６５ｍｍの球状頭部模型Ｍｄが衝突する位置を試験する際の構成、および、その衝突位置を示したものである。 The vehicle display device 100 is located below the occupant's head and is arranged in a range where the occupant's head can collide due to the impact when a front end collision of the vehicle occurs (hereinafter, head collision range). Can be done. When the vehicle display device 100 is attached to the head collision range, the occupant's head may collide with the upper end of the vehicle display device 100 from diagonally above due to the impact of the vehicle collision, as shown in FIG. .. FIG. 6 shows a position where a spherical head model Md having a diameter of 165 mm, which imitates the head of an occupant, collides with a vehicle display device 100 mounted on the dashboard 200 so as to protrude above the dashboard 200. It shows the configuration and the collision position.
　尚、ここでの頭部衝突範囲とは、例えば、球状頭部模型Ｍｄを所定の回転中心Ｃから所定の回転半径Ｒで回転させた際に、その球状頭部模型Ｍｄが静的に接する範囲を指す。回転半径Ｒは、例えば７０５ｍｍ等、人体の股関節点から頭部中心までの距離に相当する値に設定されていれば良い。回転半径Ｒは、６５４．５ｍｍ～７５５．５ｍｍの範囲で調整されていても良い。 The head collision range here is, for example, a range in which the spherical head model Md statically contacts when the spherical head model Md is rotated from a predetermined rotation center C with a predetermined turning radius R. Point to. The radius of gyration R may be set to a value corresponding to the distance from the hip joint point of the human body to the center of the head, such as 705 mm. The turning radius R may be adjusted in the range of 654.5 mm to 755.5 mm.
　回転中心Ｃは、例えば、シーティングリファレンスポイントとすることができる。シーティングリファレンスポイントとは、人体模型をＩＳＯ６５４９－１９８０に規定する着座方法により運転席等の座席に着座させた場合における股関節点の位置、またはこれに相当する座席上に設定した設計標準位置を指す。また、回転中心Ｃは、前後に調節できる座席にあっては、シーティングリファレンスポイントに加えて、シーティングリファレンスポイントから所定量（例えば１２７ｍｍ）前方で、かつ、所定量（例えば１９ｍｍ）鉛直上方に移動した点を採用することができる。 The center of rotation C can be, for example, a seating reference point. The seating reference point refers to the position of the hip joint point when the human body model is seated in a seat such as the driver's seat by the seating method specified in ISO 6549-1980, or the design standard position set on the seat corresponding thereto. Further, in the seat that can be adjusted back and forth, the rotation center C is moved forward by a predetermined amount (for example, 127 mm) and vertically upward by a predetermined amount (for example, 19 mm) from the seating reference point in addition to the seating reference point. Points can be adopted.
　尚、以上の試験構成において衝突位置に頭部からの衝撃が作用する方向は、衝突位置における接線に垂直な方向（つまり衝突位置における法線方向）となる。また、頭部模型の衝突試験は、時速２０ｋｍ／ｈで走行している車両が前端衝突した場合を想定して実施されれば良い。例えば、頭部模型の衝突速度は２０±１ｋｍ／ｈに設定されれば良い。 In the above test configuration, the direction in which the impact from the head acts on the collision position is the direction perpendicular to the tangent line at the collision position (that is, the normal direction at the collision position). Further, the collision test of the head model may be performed on the assumption that a vehicle traveling at a speed of 20 km / h collides with the front end. For example, the collision speed of the head model may be set to 20 ± 1 km / h.
　ここで、仮にベゼル部５３がカバー部材６の表面よりも奥側（背面側）に位置するように構成されている場合、頭部がカバー部材６のエッジ部６１に直接的に衝突しうる。そのため、カバー部材６が相対的に割れやすい。エッジ部６１は、端部とも称される。エッジ部６１には角部も含まれる。カバー部材６のベゼル部５３がカバー部材６の表面よりも奥側に位置するように構成した車両用表示装置において、上記した頭部衝突試験を実施したところ、カバー部材６が相対的に割れやすいことが確認された。 Here, if the bezel portion 53 is configured to be located on the back side (back side side) of the surface of the cover member 6, the head portion may directly collide with the edge portion 61 of the cover member 6. Therefore, the cover member 6 is relatively liable to crack. The edge portion 61 is also referred to as an end portion. The edge portion 61 also includes a corner portion. When the above-mentioned head collision test was performed on a vehicle display device configured such that the bezel portion 53 of the cover member 6 is located on the back side of the surface of the cover member 6, the cover member 6 is relatively liable to crack. It was confirmed that.
　これに対し、本実施形態の構成では、包囲部材５のうち、ディスプレイ１の上側に位置する部分の前端部、つまりベゼル部（上方視認側端部）５３は、カバー部材６の表面よりも視認側に突出するように構成されている。故に、乗員の頭部との１次衝突位置は、ベゼル部５３となり、車両用表示装置１００と頭部との衝突による衝撃がカバー部材６のエッジ部６１へ直接印加されることを抑制することができる。 On the other hand, in the configuration of the present embodiment, the front end portion, that is, the bezel portion (upper viewing side end portion) 53 of the portion of the surrounding member 5 located on the upper side of the display 1 is more visible than the surface of the cover member 6. It is configured to protrude to the side. Therefore, the primary collision position with the occupant's head is the bezel portion 53, and the impact due to the collision between the vehicle display device 100 and the head is suppressed from being directly applied to the edge portion 61 of the cover member 6. Can be done.
　また、図７に示すように、ベゼル部５３は、乗員頭部Ｍｇの衝突によってカバー部材６のエッジ部６１側へと変形可能となっている。ベゼル部５３が変形することにより、衝突時の衝撃荷重が低減（吸収）されるので、カバー部材６への衝撃を低減することができる。 Further, as shown in FIG. 7, the bezel portion 53 can be deformed to the edge portion 61 side of the cover member 6 by the collision of the occupant head Mg. By deforming the bezel portion 53, the impact load at the time of collision is reduced (absorbed), so that the impact on the cover member 6 can be reduced.
　また、包囲部材５の延設部５４は、フレーム３の延設部３２に接合されている。これにより、ベゼル部５３に乗員の頭部Ｍｇが当たるときに、ベゼル部５３に対して包囲部材５（周壁部５１および延設部５４）の背面側が、シーソーのように衝撃方向とは逆方向に変位するのを抑制することができるので、ベゼル部５３での変形が確実に行われて、衝撃の低減を果たすことができる。 Further, the extending portion 54 of the surrounding member 5 is joined to the extending portion 32 of the frame 3. As a result, when the occupant's head Mg hits the bezel portion 53, the back side of the surrounding member 5 (peripheral wall portion 51 and extension portion 54) with respect to the bezel portion 53 is in the direction opposite to the impact direction like a seesaw. Since it is possible to suppress the displacement to the bezel portion 53, the bezel portion 53 is surely deformed, and the impact can be reduced.
　図７において、（ａ）、（ｂ）は、頭部Ｍｇがベゼル部５３に衝突することによって生じる変位および／または変形を示している。（ａ）は、一次的な衝撃ＳＰを示している。ベゼル部５３の初期形状は、庇状に延びだしている。ベゼル部５３の初期形状は、エッジ部６１と平行に延びており、カバー部材６の表面より突出している。（ｂ）は、二次的な衝撃ＳＳを示している。延設部３２および延設部５４は、衝撃ＳＰおよび衝撃ＳＳの方向に沿って広がる板状の部材である。延設部３２および延設部５４は、衝撃ＳＰおよび衝撃ＳＳの方向における変位および変形が抑制されており、初期形状ＩＮＴを維持している。ベゼル部５３は、衝撃ＳＰによって変形し、変形後の形状５３ａである。 In FIG. 7, (a) and (b) show displacements and / or deformations caused by the head Mg colliding with the bezel portion 53. (A) shows the primary impact SP. The initial shape of the bezel portion 53 extends like an eave. The initial shape of the bezel portion 53 extends parallel to the edge portion 61 and protrudes from the surface of the cover member 6. (B) shows a secondary impact SS. The extension portion 32 and the extension portion 54 are plate-shaped members that extend along the directions of the impact SP and the impact SS. Displacement and deformation of the extension portion 32 and the extension portion 54 in the directions of the impact SP and the impact SS are suppressed, and the initial shape INT is maintained. The bezel portion 53 is deformed by the impact SP and has a deformed shape 53a.
　ベゼル部５３の変形後の形状５３ａは、エッジ部６１を巻き込むように湾曲した座屈形状である。ベゼル部５３の（ａ）における初期の突出量は、それが（ｂ）に図示されるように変形したときに、形状５３ａがカバー部材６の表面をわずかに覆うことがある突出量である。ディスプレイ１自身は、衝撃ＳＳにより、矢印ＶＩＩで示される方向へ回転し、沈み込む。ディスプレイ１は、全体として、直接的な関連をもつ部品形状を維持したまま、ディスプレイ１の後方へ倒れるように回転し、重力方向に下がる。ベゼル部５３における変形と、ディスプレイ１の後退変位とが、カバー部材６の破損を抑制する。 The deformed shape 53a of the bezel portion 53 is a buckling shape curved so as to involve the edge portion 61. The initial protrusion amount of the bezel portion 53 in (a) is the amount of protrusion that the shape 53a may slightly cover the surface of the cover member 6 when it is deformed as shown in (b). The display 1 itself is rotated by the impact SS in the direction indicated by the arrow VII and sinks. As a whole, the display 1 rotates so as to fall backward of the display 1 while maintaining the shape of the directly related parts, and descends in the direction of gravity. The deformation of the bezel portion 53 and the backward displacement of the display 1 suppress the damage of the cover member 6.
　また、表示本体部１０１の下側領域の一部が車両のインパネ内部部材２０２に支持されているので、図８に示すように、乗員頭部Ｍｇの衝突を受けると、表示本体部１０１の上部側は、取付けステー２１のボルト２２を起点にして、衝撃の方向に円弧を描くように変位する。このとき、フレーム３の背面側には、車両の衝突時における乗員頭部Ｍｇの衝突に対抗する補強リブ３３が設けられているので、表示本体部１０１は、折れ曲がるように破断することなく、変位可能となって衝撃力を受け流し（いなし）、乗員に対する衝撃を緩和することが可能である。 Further, since a part of the lower region of the display main body 101 is supported by the instrument panel internal member 202 of the vehicle, as shown in FIG. 8, when the occupant head Mg collides, the upper part of the display main body 101 is displayed. The side is displaced so as to draw an arc in the direction of impact, starting from the bolt 22 of the mounting stay 21. At this time, since the reinforcing rib 33 is provided on the back side of the frame 3 to counter the collision of the occupant head Mg at the time of the collision of the vehicle, the display main body 101 is displaced without breaking so as to bend. It is possible to parry the impact force and mitigate the impact on the occupants.
　図８において、（ａ）、（ｂ）は、頭部Ｍｇがディスプレイ１に衝突することによって生じる変位および／または変形を示している。（ａ）は、一次的な衝撃ＳＰを示している。ディスプレイ１は、矢印ＶＩＩＩの方向へ回転する。言い換えると、ディスプレイ１は、全体として、ディスプレイ１の後方へ倒れるように回転する。（ｂ）は、二次的な衝撃ＳＳを示している。回転の中心点Ｒｉは、ボルト２２における応力集中点である。　そして、表示本体部１０１が変位することによって、乗員頭部Ｍｇによる衝突の位置（２次衝突位置）は、ベゼル部５３から下側にずれるが、上記のように、ベゼル部５３の変形、および表示本体部１０１の変位により、衝突荷重がすでに低減（緩和）されていることから、カバー部材６が割れに至るおそれは回避される。 In FIG. 8, (a) and (b) show displacements and / or deformations caused by the head Mg colliding with the display 1. (A) shows the primary impact SP. Display 1 rotates in the direction of arrow VIII. In other words, the display 1 rotates so as to fall backward of the display 1 as a whole. (B) shows a secondary impact SS. The center point Ri of rotation is the stress concentration point in the bolt 22. Then, due to the displacement of the display main body 101, the position of the collision by the occupant head Mg (secondary collision position) shifts downward from the bezel 53, but as described above, the bezel 53 is deformed and the bezel 53 is deformed. Since the collision load has already been reduced (relaxed) due to the displacement of the display main body 101, the possibility that the cover member 6 will crack is avoided.
　以上のように、車両用表示装置１００への頭部Ｍｇの衝突によってカバー部材６が割れるおそれを低減することができる。 As described above, it is possible to reduce the possibility that the cover member 6 is cracked due to the collision of the head Mg with the vehicle display device 100.
　尚、上記構成においては、包囲部材５の視認側端部がいわゆるベゼルに相当する。上記の作用効果は、ベゼル部５３をカバー部材６の表面よりも視認側に突出させて、変形可能とすることによって得られる。そのため、包囲部材５の視認側端部（つまりベゼル部５３）の幅を増大させる必要性は小さい。つまり、上記の構成によれば、ベゼル幅を抑制しつつ、カバー部材６が割れにくい車両用表示装置１００を提供することができる。 In the above configuration, the visible end of the surrounding member 5 corresponds to a so-called bezel. The above-mentioned action and effect can be obtained by projecting the bezel portion 53 toward the visible side from the surface of the cover member 6 so as to be deformable. Therefore, there is little need to increase the width of the visible end portion (that is, the bezel portion 53) of the surrounding member 5. That is, according to the above configuration, it is possible to provide the vehicle display device 100 in which the cover member 6 is hard to break while suppressing the bezel width.
　尚、衝突時における乗員頭部の表示本体部１０１に対する衝突方向は、各種車両における表示本体部１０１の搭載位置等により、上方側～斜め上方側など、ある程度の幅を持つが、本実施形態の構成によれば、衝撃方向によらず安定した効果が得られ、共通の車両用表示装置１００として、各種車両への展開が可能である。 The collision direction of the occupant's head with respect to the display main body 101 at the time of a collision has a certain width such as from the upper side to the diagonally upper side depending on the mounting position of the display main body 101 in various vehicles, but in the present embodiment. According to the configuration, a stable effect can be obtained regardless of the impact direction, and the common vehicle display device 100 can be deployed in various vehicles.
　（第２実施形態）
　第２実施形態の車両用表示装置１００Ａを図９に示す。第２実施形態の車両用表示装置１００Ａは、上記第１実施形態の車両用表示装置１００に対して、包囲部材５におけるカバー受け部５２の形状を変更し、弾性接着部材９を追加したものとしている。 (Second Embodiment)
The vehicle display device 100A of the second embodiment is shown in FIG. In the vehicle display device 100A of the second embodiment, the shape of the cover receiving portion 52 in the surrounding member 5 is changed and the elastic adhesive member 9 is added to the vehicle display device 100 of the first embodiment. There is.
　包囲部材５において、カバー受け部５２の領域（上下方向寸法）は、周壁部５１側から延設部５４の下面側の位置までに短縮されている。つまり、受け面５２１の面積が縮小されている。 In the surrounding member 5, the area (vertical dimension) of the cover receiving portion 52 is shortened from the peripheral wall portion 51 side to the position on the lower surface side of the extending portion 54. That is, the area of the receiving surface 521 is reduced.
　一方、受け面５２１の面積が縮小された分、ディスプレイ１と、包囲部材５（延設部５４）と、カバー部材６とによって形成される空間には、弾性接着部材９が充填されている。弾性接着部材９は、例えば、シリコン系、あるいはウレタン系の液状弾性接着剤が使用されている。弾性接着部材９は、上記第１実施形態で説明した弾性接着部材７、あるいは光学接着層８と同じ材料を使用してもよい。 On the other hand, the space formed by the display 1, the surrounding member 5 (extended portion 54), and the cover member 6 is filled with the elastic adhesive member 9 because the area of the receiving surface 521 is reduced. For the elastic adhesive member 9, for example, a silicon-based or urethane-based liquid elastic adhesive is used. As the elastic adhesive member 9, the same material as the elastic adhesive member 7 or the optical adhesive layer 8 described in the first embodiment may be used.
　これにより、図９に示すように、カバー部材６に衝撃が加えられても、弾性接着部材９によって、カバー部材６を面によって受けることができるので、衝撃（衝撃による局所応力）を低減することができる。 As a result, as shown in FIG. 9, even if an impact is applied to the cover member 6, the cover member 6 can be received by the surface by the elastic adhesive member 9, so that the impact (local stress due to the impact) can be reduced. Can be done.
