　特許文献１に開示される車両用表示装置は、鉄道車両に設けられた電力供給装置から電力の供給を受け、鉄道車両に搭載された表示制御装置から送られる信号に応じて表示内容を制御する。この車両用表示装置には、電力を供給するためのケーブル、指令を送受信するためのケーブル等が接続されている。鉄道車両では、例えば、車内の温度と外気温との差によって、結露が生じて、車両用表示装置に接続されたケーブル等に水滴が付着することがある。ケーブルに付着した水滴は、重力の影響で、ケーブルを伝って鉛直方向下側に移動する。このようにケーブルを伝って移動する水滴は、ケーブルが接続される車両用表示装置の端子に到達することがある。水滴が端子に接触することは、車両用表示装置の故障の要因となることがあるため、好ましくない。この課題は、車両用表示装置に限られず、鉄道車両に搭載される任意の車載機器でも同様である。 The display device for a vehicle disclosed in Patent Document 1 receives power supply from a power supply device provided on a railway vehicle and controls display contents according to a signal sent from a display control device mounted on the railway vehicle. .. A cable for supplying electric power, a cable for transmitting and receiving commands, and the like are connected to the vehicle display device. In a railway vehicle, for example, dew condensation may occur due to a difference between the temperature inside the vehicle and the outside temperature, and water droplets may adhere to a cable or the like connected to the vehicle display device. The water droplets attached to the cable move vertically downward along the cable due to the influence of gravity. The water droplets thus traveling along the cable may reach the terminal of the vehicle display device to which the cable is connected. The contact of the water droplets with the terminals is not preferable because it may cause a failure of the vehicular display device. This problem is not limited to the vehicular display device, and is also applicable to any in-vehicle device mounted on the railway vehicle.
　本発明は上述の事情に鑑みてなされたものであり、ケーブルに付着した水滴が、車載機器を構成する電子機器とケーブルとの接続部分に到達することを防止する車載機器を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an in-vehicle device that prevents water droplets attached to a cable from reaching a connection portion between an electronic device that constitutes the in-vehicle device and the cable. And
　上記目的を達成するために、本発明の車載機器は、車両に搭載される車載機器であって、電子機器と、筐体と、ガイドと、を備える。筐体は、電子機器を収容する。ガイドは、一端が電子機器に接続されるケーブルを、電子機器が稼働時の基準姿勢にある状態で、電子機器に接続された一端の鉛直方向の位置より低い位置を通って配設されて筐体の外側に引き出されるよう導く。 In order to achieve the above object, the in-vehicle device of the present invention is an in-vehicle device mounted on a vehicle, and includes an electronic device, a housing, and a guide. The housing houses the electronic device. The guide is provided with a cable, one end of which is connected to the electronic device, and is disposed through a position lower than a vertical position of the one end connected to the electronic device in a state where the electronic device is in the standard posture during operation. Guide it to the outside of the body.
　本発明によれば、ガイドは、一端が電子機器に接続されるケーブルを、電子機器が稼働時の基準姿勢にある状態で、電子機器に接続された一端の鉛直方向の位置より低い位置を通って配設されて筐体の外側に引き出されるよう導く。このため、ケーブルに付着した水滴がケーブルを伝って電子機器とケーブルとの接続部分に到達することを防止することができる。 According to the present invention, the guide passes through the cable whose one end is connected to the electronic device at a position lower than the vertical position of the one end which is connected to the electronic device in a state where the electronic device is in the standard posture during operation. And is guided so as to be pulled out to the outside of the housing.

The vertical position of the opening 123 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. Therefore, the cable 11 is arranged in the space 14 through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is horizontally positioned.
　上記構成を有する車両用表示装置１０のケーブル１１には、結露等によって、水滴が付着することがある。水滴は、重力の影響で、ケーブル１１を伝って鉛直方向下側に移動する。開口１２３はケーブル１１の一端の鉛直方向の位置より低い、換言すれば、端子１３ａは開口１２３より鉛直方向上側に位置するため、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Water droplets may adhere to the cable 11 of the vehicle display device 10 having the above configuration due to dew condensation or the like. The water droplets move downward in the vertical direction along the cable 11 due to the influence of gravity. The opening 123 is lower than the position of one end of the cable 11 in the vertical direction, in other words, the terminal 13a is located above the opening 123 in the vertical direction, so that water droplets are prevented from reaching the terminal 13a through the cable 11. ..
　上述したように、上記構成を有する車両用表示装置１０によれば、鉄道車両１が水平に位置する状態で、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 As described above, according to the vehicle display device 10 having the above-described configuration, it is possible to prevent water droplets from traveling along the cable 11 and reaching the terminal 13a when the railway vehicle 1 is positioned horizontally.
　次に、図１でドア３の乗客から見て右側に位置する車両用表示装置２０について図６および図７を用いて説明する。図６および図７に示す車両用表示装置２０の基本構成は、図２から図５に示す車両用表示装置１０と同じである。なお車両用表示装置２０が備える筐体１２は、車両用表示装置１０が備える筐体１２をＸ軸回りに１８０°回転させたものである。そのため、図７に示すように、開口１２３の鉛直方向の位置は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高い。また開口１２２の鉛直方向の位置は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。なお表示端末１３は、１８０°回転された状態で配置された場合に、画像を１８０°回転させて画面に表示する機能を有する。 Next, the vehicle display device 20 located on the right side of the door 3 as seen from the passengers in FIG. 1 will be described with reference to FIGS. 6 and 7. The basic configuration of the vehicle display device 20 shown in FIGS. 6 and 7 is the same as that of the vehicle display device 10 shown in FIGS. 2 to 5. The housing 12 included in the vehicle display device 20 is obtained by rotating the housing 12 included in the vehicle display device 10 by 180° around the X axis. Therefore, as shown in FIG. 7, the vertical position of the opening 123 is higher than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is horizontally positioned. Further, the vertical position of the opening 122 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is horizontally positioned. The display terminal 13 has a function of rotating an image by 180° and displaying the image on the screen when the display terminal 13 is arranged in a state of being rotated by 180°.
　車両用表示装置２０が有するケーブル１１の一端は、端子１３ａに接続され、ケーブル１１の他端は、開口１２２を通って、筐体１２の外側に引き出され、制御装置４に接続されている。開口１２２の鉛直方向の位置は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低いため、ケーブル１１は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って空間１４に配設されている。 The one end of the cable 11 included in the vehicle display device 20 is connected to the terminal 13 a, and the other end of the cable 11 is pulled out to the outside of the housing 12 through the opening 122 and connected to the control device 4. Since the vertical position of the opening 122 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13, the cable 11 is attached to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. It is disposed in the space 14 through a position lower than the vertical position of one end of the connected cable 11.
　上記構成を有する車両用表示装置２０の筐体１２のケーブル１１には、結露等によって、水滴が付着することがある。水滴は、重力の影響で、ケーブル１１を伝って鉛直方向下側に移動する。開口１２２はケーブル１１の一端の鉛直方向の位置より低い、換言すれば、端子１３ａは開口１２２より鉛直方向上側に位置するため、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Water droplets may adhere to the cable 11 of the housing 12 of the vehicle display device 20 having the above configuration due to dew condensation or the like. The water droplets move downward in the vertical direction along the cable 11 due to the influence of gravity. The opening 122 is lower than the position of one end of the cable 11 in the vertical direction, in other words, the terminal 13a is located above the opening 122 in the vertical direction, so that water droplets are prevented from reaching the terminal 13a through the cable 11. ..
　さらに鉄道車両１が斜面に位置している状態でも、水滴がケーブル１１を伝って端子１３ａに到達することが防止されることが好ましい。具体的には、ケーブル１１は、鉄道車両１が斜面に位置している状態でも、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通るように配設されることが好ましい。 Furthermore, it is preferable to prevent water droplets from traveling along the cable 11 and reaching the terminal 13a even when the railway vehicle 1 is located on the slope. Specifically, the cable 11 should be disposed so as to pass through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13 even when the railway vehicle 1 is located on the slope. Is preferred.
　その場合、図５に示すように、鉄道車両１が、傾斜角が最大となる斜面に位置している状態で、開口１２３の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置Ｈ１より低くなるように、開口１２３の位置を定めればよい。具体的には、図３に示すように、鉄道車両１が水平に位置している状態で、開口１２３と端子１３ａとを結ぶ直線Ｌ１が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置Ｈ１を通るＹ軸に平行な水平軸となす角θ１を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすることが好ましい。 In that case, as shown in FIG. 5, in the state where the railway vehicle 1 is located on the slope having the maximum inclination angle, the vertical position of the opening 123 is at one end of the cable 11 connected to the display terminal 13. The position of the opening 123 may be determined so as to be lower than the position H1 in the vertical direction. Specifically, as shown in FIG. 3, a straight line L1 connecting the opening 123 and the terminal 13a is a vertical line at one end of the cable 11 connected to the display terminal 13 when the railway vehicle 1 is horizontally positioned. It is preferable that the angle θ1 formed with the horizontal axis parallel to the Y-axis passing through the directional position H1 is larger than the maximum value of the inclination angle on the route on which the railway vehicle 1 travels.
　この結果、側面１２ｂの外面が鉄道車両１の進行方向前方を向き、かつ、鉄道車両１が、傾斜角が最大となる上り斜面に位置している状態で、開口１２３の鉛直方向の位置は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。また側面１２ｂの外面が鉄道車両１の進行方向後方を向き、かつ、傾斜角が最大となる下り斜面に位置している状態でも、開口１２３の鉛直方向の位置は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。このため、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 As a result, with the outer surface of the side surface 12b facing forward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being located on the upslope having the maximum inclination angle, the vertical position of the opening 123 is It is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. The vertical position of the opening 123 is connected to the display terminal 13 even when the outer surface of the side surface 12b faces rearward in the traveling direction of the railway vehicle 1 and is located on the downward slope having the maximum inclination angle. It is lower than the vertical position of one end of the cable 11. Therefore, even if the railway vehicle 1 is located on the slope, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　同様に、鉄道車両１が、傾斜角が最大となる斜面に位置している状態で、開口１２２の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低くなるように、開口１２２の位置を定めればよい。具体的には、図７に示すように、鉄道車両１が水平に位置している状態で、開口１２２と端子１３ａとを結ぶ直線Ｌ２が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置Ｈ１を通るＹ軸に平行な水平軸となす角θ２を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすることが好ましい。 Similarly, in the state where the railway vehicle 1 is located on the slope having the maximum inclination angle, the vertical position of the opening 122 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. The position of the opening 122 may be determined so that Specifically, as shown in FIG. 7, a straight line L2 connecting the opening 122 and the terminal 13a is a vertical line at one end of the cable 11 connected to the display terminal 13 when the railway vehicle 1 is horizontally positioned. It is preferable that the angle θ2 formed with the horizontal axis parallel to the Y-axis passing through the directional position H1 be larger than the maximum value of the inclination angle on the route on which the railway vehicle 1 travels.
　この結果、側面１２ｂの外面が鉄道車両１の進行方向前方を向き、かつ、鉄道車両１が、傾斜角が最大となる上り斜面に位置している状態で、開口１２２の鉛直方向の位置は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。また側面１２ｂの外面が鉄道車両１の進行方向後方を向き、かつ、鉄道車両１が、傾斜角が最大となる下り斜面に位置している状態で、開口１２２の鉛直方向の位置は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。 As a result, with the outer surface of the side surface 12b facing forward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being located on the upslope having the maximum inclination angle, the vertical position of the opening 122 is: It is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. Further, in a state in which the outer surface of the side surface 12b faces rearward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 is located on the descending slope having the maximum inclination angle, the vertical position of the opening 122 is It is lower than the vertical position of one end of the cable 11 connected to 13.
　以上説明したとおり、本実施の形態１に係る車両用表示装置１０，２０によれば、ケーブル１１は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って配設される。これによって、ケーブル１１に付着した水滴が、ケーブル１１を伝って端子１３ａに到達することが防止される。この結果、ケーブル１１に付着した水滴によって、車両用表示装置１０，２０が故障することを抑制することができる。 As described above, according to the vehicular display devices 10 and 20 according to the first embodiment, the cable 11 is arranged through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13. Is set up. This prevents water droplets attached to the cable 11 from reaching the terminal 13a along the cable 11. As a result, it is possible to prevent the vehicle display devices 10 and 20 from being damaged by water droplets attached to the cable 11.
　また車両用表示装置１０の筐体１２と車両用表示装置２０の筐体１２の構造は同じである。表示端末１３は、１８０°回転された状態で配置された場合に、画像を１８０°回転させて画面に表示する機能を有する。この結果、車両用表示装置１０の筐体１２をＸ軸周りに１８０°回転させたものを用いて、車両用表示装置２０を構成することができるため、車両用表示装置１０，２０とで構成部材を共通化することができ、製造コストを低減することが可能である。 The structure of the housing 12 of the vehicle display device 10 and the structure of the housing 12 of the vehicle display device 20 are the same. The display terminal 13 has a function of rotating an image by 180° and displaying the image on the screen when the display terminal 13 is arranged in a state of being rotated by 180°. As a result, since the vehicle display device 20 can be configured by using the casing 12 of the vehicle display device 10 rotated about the X axis by 180°, the vehicle display device 10 and the vehicle display device 10 are configured. The members can be made common and the manufacturing cost can be reduced.
　好ましくは、鉄道車両１が、傾斜角が最大となる斜面に位置している状態で、車両用表示装置１０の開口１２３の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低くなるように開口１２３の位置を定めればよい。また好ましくは、鉄道車両１が、傾斜角が最大となる斜面に位置している状態で、車両用表示装置２０の開口１２２の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低くなるように開口１２２の位置を定めればよい。この結果、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Preferably, in the state in which the railway vehicle 1 is located on the slope having the maximum inclination angle, the vertical position of the opening 123 of the vehicle display device 10 is at the one end of the cable 11 connected to the display terminal 13. The position of the opening 123 may be determined so as to be lower than the position in the vertical direction. Further, preferably, in the state where the railway vehicle 1 is located on the slope having the maximum inclination angle, the vertical position of the opening 122 of the vehicle display device 20 is set at one end of the cable 11 connected to the display terminal 13. The position of the opening 122 may be determined so as to be lower than the position in the vertical direction of. As a result, even when the railway vehicle 1 is located on the slope, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　ドア３の横に車両用表示装置１０，２０を配置する場合、ケーブル１１を配線するためのスペースに制限があり、水滴が端子１３ａに到達することを防ぐために端子１３ａの差込口を鉛直方向下向きに向けることができないことがある。そのような場合でも、実施の形態１に係る車両用表示装置１０，２０によれば、ケーブル１１に付着した水滴が、ケーブル１１を伝って端子１３ａに到達することが防止される。換言すれば、端子１３ａの差込口の向きまたはケーブル１１を配線するためのスペースが制限される場合に、実施の形態１に係る車両用表示装置１０，２０は、水滴が端子１３ａに到達することを防止可能である。 When the vehicle display devices 10 and 20 are arranged beside the door 3, the space for wiring the cable 11 is limited, and the insertion port of the terminal 13a is arranged in the vertical direction in order to prevent water droplets from reaching the terminal 13a. It may not be possible to point downwards. Even in such a case, the vehicle display devices 10 and 20 according to the first embodiment prevent water droplets attached to the cable 11 from reaching the terminal 13a along the cable 11. In other words, when the direction of the insertion port of the terminal 13a or the space for wiring the cable 11 is limited, in the vehicular display devices 10 and 20 according to the first embodiment, water droplets reach the terminal 13a. It is possible to prevent that.
　（実施の形態２）
　ケーブル１１を、鉄道車両１が水平に位置している状態で、表示端末１３に接続された一端の鉛直方向の位置より低い位置を通って配設されて筐体１２の外側に引き出されるよう導くガイドの構造は、実施の形態１の例に限られない。ガイドの一例として、筐体の内面からＸ軸方向に延びる突起を有する車両用表示装置について実施の形態２で説明する。 (Embodiment 2)
Guide the cable 11 through the position lower than the vertical position of one end connected to the display terminal 13 in the state where the railway vehicle 1 is horizontally positioned and pulled out to the outside of the housing 12. The structure of the guide is not limited to the example of the first embodiment. As an example of the guide, a vehicle display device having a protrusion extending from the inner surface of the housing in the X-axis direction will be described in the second embodiment.
　図８から図１０に示す実施の形態２に係る車両用表示装置３０の基本構成は、実施の形態１に係る車両用表示装置１０の基本構成と同様である。車両用表示装置１０と異なる点について説明する。 The basic configuration of the vehicle display device 30 according to the second embodiment shown in FIGS. 8 to 10 is the same as the basic configuration of the vehicle display device 10 according to the first embodiment. Differences from the vehicle display device 10 will be described.
　車両用表示装置３０は、筐体１２に代えて、筐体３１を備える。図８に示すように、筐体３１は、Ｘ軸に直交する主面３１ａに開口部３１１を有し、Ｙ軸に直交する側面３１ｂに開口３１２を有する。さらに筐体３１は、図９および図１０に示すように、ケーブル１１を配設するための空間３２を内部に有する。また車両用表示装置３０は、筐体３１の内面３１ｃからＸ軸方向に延びる突起３３を有する。
　図８に示すように、筐体３１は、表示端末１３の画面を開口部３１１に向けて、表示端末１３を収容する。
　開口３１２は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置と同等の高さに位置する。 The vehicle display device 30 includes a housing 31 instead of the housing 12. As shown in FIG. 8, the housing 31 has an opening 311 on a main surface 31a orthogonal to the X axis and an opening 312 on a side surface 31b orthogonal to the Y axis. Further, as shown in FIGS. 9 and 10, the housing 31 has a space 32 inside for housing the cable 11. The vehicular display device 30 also has a protrusion 33 extending in the X-axis direction from the inner surface 31c of the housing 31.
As shown in FIG. 8, the housing 31 accommodates the display terminal 13 with the screen of the display terminal 13 facing the opening 311.
The opening 312 is positioned at the same height as the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally.
　突起３３の鉛直方向下端は、図９に示すように、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。また突起３３の鉛直方向上端は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高い。なお図９は、鉄道車両１が水平に位置する状態での車両用表示装置１０の背面図である。図９において、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置、すなわち、端子１３ａの鉛直方向の位置を一点鎖線で示す。 As shown in FIG. 9, the vertical lower end of the protrusion 33 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. The upper end of the protrusion 33 in the vertical direction is higher than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. Note that FIG. 9 is a rear view of the vehicle display device 10 in a state where the railway vehicle 1 is horizontally positioned. In FIG. 9, the vertical position of one end of the cable 11 connected to the display terminal 13, that is, the vertical position of the terminal 13a is indicated by a dashed line.
　ケーブル１１の一端は、端子１３ａに接続され、ケーブル１１の他端は、開口３１２を通って、筐体３１の外側に引き出され、制御装置４に接続されている。なおケーブル１１は、突起３３の鉛直方向下端に沿って配設される。突起３３の鉛直方向下端は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低いため、ケーブル１１は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って空間３２に配設されている。 One end of the cable 11 is connected to the terminal 13 a, and the other end of the cable 11 is pulled out to the outside of the housing 31 through the opening 312 and connected to the control device 4. The cable 11 is arranged along the lower end of the protrusion 33 in the vertical direction. Since the lower end of the protrusion 33 in the vertical direction is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally, the cable 11 is Is located in the space 32 through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13.
　上記構成を有する車両用表示装置３０が有する突起３３の鉛直方向下端に沿って配設されるケーブル１１には、結露等によって、水滴が付着することがある。水滴は、ケーブル１１を伝って鉛直方向下側に移動する。突起３３の鉛直方向下端はケーブル１１の一端の鉛直方向の位置より低いため、端子１３ａは突起３３の鉛直方向下端より鉛直方向上側に位置する。この結果、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Water droplets may adhere to the cable 11 arranged along the vertical lower end of the protrusion 33 of the vehicle display device 30 having the above configuration due to dew condensation or the like. The water droplets travel along the cable 11 and move downward in the vertical direction. Since the lower end of the protrusion 33 in the vertical direction is lower than the vertical position of the one end of the cable 11, the terminal 13a is located above the lower end of the protrusion 33 in the vertical direction. As a result, water droplets are prevented from reaching the terminal 13a through the cable 11.
　上述したように、上記構成を有する車両用表示装置３０によれば、鉄道車両１が水平に位置する状態で、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。　 As described above, according to the vehicle display device 30 having the above-described configuration, it is possible to prevent water droplets from traveling along the cable 11 and reaching the terminal 13a when the railway vehicle 1 is positioned horizontally. ‥
　またドア３の乗客から見て左右に設けられた車両用表示装置の構成部材を共通化するためには、図９に示すように、鉄道車両１が水平に位置している状態で、突起３３の鉛直方向上端を、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高くすればよい。具体的には、鉄道車両１が水平に位置している状態で、突起３３の鉛直方向上端と端子１３ａとを結ぶ直線が水平方向となす角は、鉄道車両１が走行する路線での傾斜角の最大値より大きい。これにより、上記構成を有する筐体３１をＸ軸回りに１８０°回転させて、ドア３の乗客から見て右側に位置する車両用表示装置３０を構成することができ、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Further, in order to share the constituent members of the vehicle display device provided on the left and right when viewed from the passengers of the door 3, as shown in FIG. The upper end in the vertical direction may be higher than the vertical position of one end of the cable 11 connected to the display terminal 13. Specifically, when the railway vehicle 1 is horizontally positioned, the angle formed by the straight line connecting the vertical upper end of the protrusion 33 and the terminal 13a with the horizontal direction is the inclination angle on the route on which the railway vehicle 1 runs. Is greater than the maximum value of. This makes it possible to rotate the housing 31 having the above-described configuration by 180° about the X-axis to configure the vehicle display device 30 located on the right side of the passenger of the door 3 and the railway vehicle 1 on the slope. Even if it is located, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　さらに鉄道車両１が斜面に位置している状態でも、水滴がケーブル１１を伝って端子１３ａに到達することが防止されることが好ましい。具体的には、ケーブル１１は、鉄道車両１が斜面に位置している状態でも、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通るように配設されることが好ましい。 Furthermore, it is preferable to prevent water droplets from traveling along the cable 11 and reaching the terminal 13a even when the railway vehicle 1 is located on the slope. Specifically, the cable 11 should be disposed so as to pass through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13 even when the railway vehicle 1 is located on the slope. Is preferred.
　その場合、鉄道車両１が走行する路線の各地点の傾斜角に基づき、鉄道車両１が、傾斜が最大となる斜面に位置している状態で、突起３３の鉛直方向下端が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低くなるように、突起３３の鉛直方向下端の位置を定めればよい。具体的には、鉄道車両１が水平に位置している状態で、突起３３の鉛直方向下端と端子１３ａとを結ぶ直線が水平方向となす角を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすることが好ましい。 In that case, based on the inclination angle of each point of the route on which the railway vehicle 1 travels, the vertical lower end of the protrusion 33 is displayed on the display terminal 13 in a state in which the railway vehicle 1 is located on the slope having the maximum inclination. The position of the lower end of the protrusion 33 in the vertical direction may be determined so as to be lower than the position of the one end of the connected cable 11 in the vertical direction. Specifically, when the railway vehicle 1 is horizontally positioned, the angle formed by the straight line connecting the lower end of the protrusion 33 in the vertical direction and the terminal 13a with the horizontal direction is the inclination angle on the route on which the railway vehicle 1 travels. Is preferably larger than the maximum value of.
　この結果、側面３１ｂの外面が、鉄道車両１の進行方向前方を向き、かつ、鉄道車両１が、傾斜角が最大となる上り斜面に位置している状態で、突起３３の鉛直方向下端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。また側面３１ｂの外面が、鉄道車両１の進行方向後方を向き、かつ、鉄道車両１が、傾斜角が最大となる下り斜面に位置している状態で、突起３３の鉛直方向下端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。このため、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 As a result, with the outer surface of the side surface 31b facing forward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being positioned on the upslope having the maximum inclination angle, the vertical lower end of the protrusion 33 is It is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. Further, in a state where the outer surface of the side surface 31b faces rearward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 is located on the downward slope having the maximum inclination angle, the vertical lower end of the protrusion 33 is the display terminal. It is lower than the vertical position of one end of the cable 11 connected to 13. Therefore, even if the railway vehicle 1 is located on the slope, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　なおドア３の乗客から見て左右に設けられた車両用表示装置３０の構成部材を共通化する場合には、鉄道車両１が水平に位置している状態で、突起３３の鉛直方向上端と端子１３ａとを結ぶ直線が水平方向となす角を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすることが好ましい。 Note that when the constituent members of the vehicle display device 30 provided on the left and right of the door 3 when viewed from the passengers are shared, the vertical upper end of the protrusion 33 and the terminal in the state where the railway vehicle 1 is positioned horizontally. It is preferable that the angle formed by the straight line connecting 13a with the horizontal direction is larger than the maximum value of the inclination angle on the route on which the railway vehicle 1 runs.
　以上説明した通り、本実施の形態２に係る車両用表示装置３０によれば、ケーブル１１は、突起３３の鉛直方向下端に沿って配設される。これによって、ケーブル１１に付着した水滴が、ケーブル１１を伝って端子１３ａに到達することが防止される。この結果、ケーブル１１に付着した水滴によって、車両用表示装置３０が故障することを抑制することができる。 As described above, according to the vehicle display device 30 of the second embodiment, the cable 11 is arranged along the lower end of the protrusion 33 in the vertical direction. This prevents water droplets attached to the cable 11 from reaching the terminal 13a along the cable 11. As a result, it is possible to prevent the vehicle display device 30 from breaking down due to water droplets attached to the cable 11.
　また車両用表示装置３０の筐体３１をＸ軸周りに１８０°回転させることで、ドア３の乗客から見て右側に設けられた車両用表示装置３０を構成することができる。そのため、ドア３の乗客から見て左右に設けられた車両用表示装置３０の構成部材を共通化することができ、製造コストを低減することが可能である。 Further, by rotating the housing 31 of the vehicle display device 30 by 180° around the X axis, the vehicle display device 30 provided on the right side of the passenger of the door 3 as viewed from the passenger can be configured. Therefore, the constituent members of the vehicle display device 30 provided on the left and right of the door 3 when viewed from the passengers can be shared, and the manufacturing cost can be reduced.
　好ましくは、傾斜が最大となる斜面に位置している状態で、車両用表示装置３０の突起３３の鉛直方向下端が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低くなるように、突起３３の鉛直方向下端の位置を定めればよい。この結果、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Preferably, the vertical lower end of the protrusion 33 of the vehicular display device 30 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where it is positioned on the slope having the maximum inclination. Thus, the position of the lower end of the protrusion 33 in the vertical direction may be determined. As a result, even when the railway vehicle 1 is located on the slope, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　（実施の形態３）
　車両用表示装置は、ケーブル１１の任意の位置で、ケーブル１１の鉛直方向下端に当接し、ケーブル１１に当接する位置から表示端末１３の方向にケーブル１１に付着した水滴が移動することを防止する移動防止部材をさらに備えてもよい。移動防止部材を備える車両用表示装置の構造を実施の形態３で説明する。 (Embodiment 3)
The vehicular display device contacts the vertical lower end of the cable 11 at an arbitrary position of the cable 11, and prevents water droplets attached to the cable 11 from moving from the position of contacting the cable 11 toward the display terminal 13. You may further provide a movement prevention member. The structure of the vehicle display device including the movement preventing member will be described in the third embodiment.
　図１１および図１２に示す実施の形態３に係る車両用表示装置４０の基本構成は、実施の形態３に係る車両用表示装置３０の基本構成と同様である。車両用表示装置３０と異なる点について説明する。 The basic configuration of the vehicle display device 40 according to the third embodiment shown in FIGS. 11 and 12 is the same as the basic configuration of the vehicle display device 30 according to the third embodiment. Differences from the vehicle display device 30 will be described.
　車両用表示装置４０は、車両用表示装置３０が有する突起３３に代えて、ケーブル１１の任意の位置で、ケーブル１１の鉛直方向下端に当接する移動防止部材３４を備える。移動防止部材３４は、端子１３ａに隣接する。具体的には、移動防止部材３４は、端子１３ａから離隔した状態で、端子１３ａに可能な限り近づけて配置されることが好ましい。なお移動防止部材３４は、内周面がケーブル１１に当接する環状部材で構成される。好ましくは、移動防止部材３４は、撥水性を有する部材、例えば、ゴム、樹脂等で形成される。 The vehicle display device 40 includes a movement preventing member 34 that abuts the lower end of the cable 11 in the vertical direction at an arbitrary position of the cable 11, instead of the protrusion 33 included in the vehicle display device 30. The movement preventing member 34 is adjacent to the terminal 13a. Specifically, it is preferable that the movement preventing member 34 is arranged as close to the terminal 13a as possible in a state of being separated from the terminal 13a. The movement prevention member 34 is an annular member whose inner peripheral surface abuts on the cable 11. Preferably, the movement preventing member 34 is made of a water-repellent member such as rubber or resin.
　ケーブル１１の一端は、端子１３ａに接続され、ケーブル１１の他端は、開口３１２を通って、筐体３１の外側に引き出され、制御装置４に接続されている。なおケーブル１１は、端子１３ａから開口３１２に向かって延びるように配設される。 One end of the cable 11 is connected to the terminal 13 a, and the other end of the cable 11 is pulled out to the outside of the housing 31 through the opening 312 and connected to the control device 4. The cable 11 is arranged so as to extend from the terminal 13a toward the opening 312.
　上記構成を有する車両用表示装置４０のケーブル１１には、結露等によって、水滴が付着することがある。水滴は、ケーブル１１を伝って鉛直方向下側に移動する。ケーブル１１には、内周面がケーブル１１に当接する環状部材で構成される移動防止部材３４が固定されているため、水滴が端子１３ａに向かって移動することが防止される。 Water droplets may adhere to the cable 11 of the vehicle display device 40 having the above configuration due to dew condensation or the like. The water droplets travel along the cable 11 and move downward in the vertical direction. Since the movement preventing member 34, which is an annular member whose inner peripheral surface abuts on the cable 11, is fixed to the cable 11, water droplets are prevented from moving toward the terminal 13a.
　以上説明した通り、本実施の形態３に係る車両用表示装置４０は、ケーブル１１の一部の鉛直方向下端に当接する移動防止部材３４を備えるため、ケーブル１１に付着した水滴がケーブル１１を伝って移動して、端子１３ａに到達することが防止される。この結果、ケーブル１１に付着した水滴によって、車両用表示装置４０が故障することを抑制することができる。 As described above, the vehicular display device 40 according to the third embodiment includes the movement preventing member 34 that abuts on the vertical lower end of a portion of the cable 11, so that water droplets attached to the cable 11 travel along the cable 11. It is prevented that the terminal 13a moves to reach the terminal 13a. As a result, it is possible to prevent the vehicle display device 40 from breaking down due to water droplets attached to the cable 11.
　また上述したように、移動防止部材３４は、環状部材で構成されており、開口３１２は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置と同等の高さに位置する。そのため、車両用表示装置４０の筐体３１をＸ軸周りに１８０°回転させることで、ドア３の乗客から見て右側に設けられた車両用表示装置を構成することができる。この結果、ドア３の乗客から見て左右に設けられた車両用表示装置の構成部材を共通化することができ、製造コストを低減することが可能である。 In addition, as described above, the movement preventing member 34 is configured by an annular member, and the opening 312 has the vertical end at one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. Located at the same height as the directional position. Therefore, by rotating the housing 31 of the vehicular display device 40 about the X axis by 180°, the vehicular display device provided on the right side of the door 3 when viewed from the passenger can be configured. As a result, the constituent members of the vehicular display device, which are provided on the left and right sides of the door 3 when viewed from the passenger, can be made common, and the manufacturing cost can be reduced.
　本発明の実施の形態は、上述の例に限られない。一例として、車両用表示装置１０，２０，３０，４０に限られず、本発明が適用される車載機器は、ケーブルが接続される車載機器であれば、任意である。車載機器の一例として、鉄道車両１の床下に取り付けられる電源装置があげられる。この場合、電子機器の稼働時の基準姿勢は、鉄道車両１が水平に位置する状態で、床下に固定された車載機器が備える電子機器の姿勢を意味する。また車載機器は、ケーブルカー、トロリーバス等の任意の車両に搭載され得る。一例として、車載機器がケーブルカーに搭載される場合、電子機器の稼働時の基準姿勢は、ケーブルカーが駅に停止している状態で、ケーブルカーに固定された車載機器が備える電子機器の姿勢を意味する。 The embodiment of the present invention is not limited to the above example. As an example, the vehicle-mounted device to which the present invention is applied is not limited to the vehicle display devices 10, 20, 30, and 40, and may be any vehicle-mounted device to which a cable is connected. An example of the in-vehicle device is a power supply device that is installed under the floor of the railway vehicle 1. In this case, the reference posture when the electronic device is in operation means the posture of the electronic device included in the vehicle-mounted device that is fixed under the floor in a state where the railway vehicle 1 is horizontally positioned. The in-vehicle device can be mounted on any vehicle such as a cable car or a trolleybus. As an example, when the on-vehicle device is mounted on the cable car, the standard posture when the electronic device is in operation is the posture of the electronic device that the on-vehicle device fixed to the cable car has while the cable car is stopped at the station. Means
　また上述の実施の形態の内、複数の実施の形態を組み合わせてもよい。車両用表示装置１０，２０，３０はそれぞれ、移動防止部材３４をさらに備えてもよい。車両用表示装置１０が移動防止部材３４をさらに備えると、鉄道車両１が急な斜面に位置し、開口１２３の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高くなっても、移動防止部材３４によって、水滴が端子１３ａに到達することが防止される。 Also, among the above-described embodiments, a plurality of embodiments may be combined. Each of the vehicle display devices 10, 20, 30 may further include a movement prevention member 34. When the vehicle display device 10 further includes the movement preventing member 34, the railway vehicle 1 is located on a steep slope, and the vertical position of the opening 123 is the vertical direction of one end of the cable 11 connected to the display terminal 13. Even when the position is higher than the position, the movement preventing member 34 prevents water droplets from reaching the terminal 13a.
　同様に、車両用表示装置２０が移動防止部材３４をさらに備えると、鉄道車両１が急な斜面に位置し、開口１２２の鉛直方向の位置が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高くなっても、移動防止部材３４によって、水滴が端子１３ａに到達することが防止される。 Similarly, when the vehicle display device 20 further includes the movement preventing member 34, the railway vehicle 1 is located on a steep slope, and the vertical position of the opening 122 is at one end of the cable 11 connected to the display terminal 13. Even when the position is higher than the vertical position, the movement preventing member 34 prevents water droplets from reaching the terminal 13a.
　また車両用表示装置３０が突起３３より端子１３ａに近い位置に移動防止部材３４を備えると、鉄道車両１が急な斜面に位置し、突起３３の鉛直方向下端が、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高くなっても、移動防止部材３４によって、水滴が端子１３ａに到達することが防止される。 When the vehicle display device 30 includes the movement preventing member 34 at a position closer to the terminal 13a than the protrusion 33, the railway vehicle 1 is located on a steep slope, and the vertical lower end of the protrusion 33 is connected to the display terminal 13. Even if the position is higher than the vertical position of one end of the cable 11, the movement preventing member 34 prevents water droplets from reaching the terminal 13a.
　また車両用表示装置１０，２０はそれぞれ、突起３３を備えてもよい。突起３３の鉛直方向下端に沿ってケーブル１１を配設することで、鉄道車両１の振動によって、空間１４でケーブル１１が鉛直方向上側に移動することが防止される。 The vehicle display devices 10 and 20 may each include a protrusion 33. By disposing the cable 11 along the lower end of the protrusion 33 in the vertical direction, the cable 11 is prevented from moving upward in the vertical direction in the space 14 due to the vibration of the railway vehicle 1.
　車両用表示装置１０，２０が有する開口１２２，１２３の形状および位置は、ケーブル１１を、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って配設されるよう導くことができれば、任意である。
　一例として、図１３に示す車両用表示装置１０が有する筐体１２は、側面１２ｂに、開口１２４，１２５を有する。図１３に示すように、開口１２４，１２５は、一端が表示端末１３に接続されるケーブル１１を、鉄道車両１が水平に位置している状態で、表示端末１３に接続された一端の鉛直方向の位置より低い位置を通って配設されて筐体１２の外側に引き出されるよう導く。開口１２４は、開口１２２と同じ位置に形成され、開口１２５は、開口１２３と同じ位置に形成される。開口１２４，１２５の貫通方向は、Ｙ軸方向に交差する。具体的には、鉄道車両１が水平に位置している状態で、筐体１２の内側から外側に向かう開口１２４の貫通方向は、鉛直方向上側に延びる。また鉄道車両１が水平に位置している状態で、筐体１２の内側から外側に向かう開口１２５の貫通方向は、鉛直方向下側に延びる。このため、筐体１２の内部に生じた水滴は、開口１２５から外部に速やかに排出される。 The shapes and positions of the openings 122 and 123 of the vehicular display devices 10 and 20 are such that the cable 11 is disposed through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13. It is optional if it can be guided.
As an example, the housing 12 included in the vehicular display device 10 illustrated in FIG. 13 has openings 124 and 125 on the side surface 12b. As shown in FIG. 13, the openings 124 and 125 connect the cable 11 whose one end is connected to the display terminal 13 in the vertical direction of the one end connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. It is disposed through a position lower than the position of and is guided so as to be drawn out of the housing 12. The opening 124 is formed at the same position as the opening 122, and the opening 125 is formed at the same position as the opening 123. The penetration directions of the openings 124 and 125 intersect with the Y-axis direction. Specifically, in a state in which the railway vehicle 1 is horizontally positioned, the penetrating direction of the opening 124 extending from the inside to the outside of the housing 12 extends upward in the vertical direction. Further, in a state in which the railway vehicle 1 is horizontally positioned, the penetrating direction of the opening 125 extending from the inside to the outside of the housing 12 extends downward in the vertical direction. Therefore, the water droplets generated inside the housing 12 are promptly discharged to the outside through the opening 125.
　また図１３に示す車両用表示装置１０が備える筐体１２をＸ軸回りに１８０°回転させたものを用いて、車両用表示装置２０を構成することが可能である。この場合、ケーブル１１は、開口１２４を通って、筐体１２の外側に引き出される。筐体１２の内部に生じた水滴は、開口１２４から外部に速やかに排出される。 Further, it is possible to configure the vehicle display device 20 by using the casing 12 included in the vehicle display device 10 shown in FIG. 13 rotated by 180° around the X axis. In this case, the cable 11 is pulled out to the outside of the housing 12 through the opening 124. The water droplets generated inside the housing 12 are quickly discharged to the outside through the opening 124.
　他の一例として、図１４および図１５に示す車両用表示装置１０が有する筐体１２は、側面１２ｂに開口１２６と、Ｚ軸方向に延びる溝１２７とを有する。また車両用表示装置１０は、一部が溝１２７に位置し、溝１２７に沿って移動可能であって、開口１２６の一部を塞ぐカバー１５と、溝１２７に位置し、カバー１５を固定する固定部材１６とをさらに備える。なお固定部材１６は、カバー１５のＺ軸方向下側の溝１２７に位置し、筐体１２に取り付けられる。そして、固定部材１６は、カバー１５をＺ軸方向に支持することで、カバー１５のＺ軸方向の移動を制限する。この結果、開口１２６のＺ軸方向下部は、カバー１５に塞がれない。
　ケーブル１１の一端は、端子１３ａに接続され、ケーブル１１の他端は、カバー１５によって塞がれていない開口１２６のＺ軸方向下部を通って、筐体１２の外側に引き出され、制御装置４に接続される。 As another example, the housing 12 included in the vehicular display device 10 shown in FIGS. 14 and 15 has an opening 126 in the side surface 12b and a groove 127 extending in the Z-axis direction. Further, the vehicle display device 10 is partially located in the groove 127, is movable along the groove 127, and covers the part of the opening 126 and the cover 15, which is located in the groove 127 and fixes the cover 15. The fixing member 16 is further provided. The fixing member 16 is located in the groove 127 on the lower side of the cover 15 in the Z-axis direction and is attached to the housing 12. The fixing member 16 limits the movement of the cover 15 in the Z-axis direction by supporting the cover 15 in the Z-axis direction. As a result, the lower portion of the opening 126 in the Z-axis direction is not blocked by the cover 15.
One end of the cable 11 is connected to the terminal 13a, and the other end of the cable 11 passes through a lower portion of the opening 126 not covered by the cover 15 in the Z-axis direction and is pulled out to the outside of the housing 12 to control the controller 4 Connected to.
　また図１４および図１５に示す車両用表示装置１０の筐体１２をＸ軸回りに１８０°回転させたものを用いて、車両用表示装置２０を構成することが可能である。この場合も、図１６に示すように、ケーブル１１の一端は、端子１３ａに接続され、ケーブル１１の他端は、カバー１５によって塞がれていない開口１２６のＺ軸方向下部を通って、筐体１２の外側に引き出され、制御装置４に接続される。 Further, it is possible to configure the vehicle display device 20 by using the casing 12 of the vehicle display device 10 shown in FIGS. 14 and 15 that is rotated by 180° around the X axis. Also in this case, as shown in FIG. 16, one end of the cable 11 is connected to the terminal 13 a, and the other end of the cable 11 passes through the lower part of the opening 126 not covered by the cover 15 in the Z-axis direction and the casing. It is pulled out of the body 12 and connected to the control device 4.
　なおカバー１５の形状および構造は、側面１２ｂでのカバー１５の位置が可変であって、開口１２６の一部を塞ぐことができる形状および構造であれば、任意である。また固定部材１６の形状および構造は、カバー１５の移動を制限する形状および構造であれば、任意である。一例として、カバー１５は、筐体１２に取り付けられ、Ｚ軸方向に延びるレールに沿って移動してもよい。 The shape and structure of the cover 15 are arbitrary as long as the position of the cover 15 on the side surface 12b is variable and the shape and structure can close a part of the opening 126. Further, the shape and the structure of the fixing member 16 are arbitrary as long as the shape and the structure limit the movement of the cover 15. As an example, the cover 15 may be attached to the housing 12 and move along a rail extending in the Z-axis direction.
　車両用表示装置１０，２０，３０のそれぞれが有するガイドの構造は、ケーブル１１を、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って配設されるよう導く構造であれば、任意である。一例として、ケーブル１１を、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高い位置を通ってから、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って配設されるよう導くガイドについて説明する。このガイドを有する車両用表示装置３０を図１７に示す。図１７に示す車両用表示装置３０は、突起３３に代えて、筐体３１の内面３１ｃからＸ軸方向に延びる突起３５，３６を備える。突起３５，３６は、ガイドとしての役割を果たす。なお図１７は、鉄道車両１が水平に位置する状態での車両用表示装置３０の変形例の背面図である。 The guide structure of each of the vehicle display devices 10, 20, and 30 has a structure in which the cable 11 is connected to the display terminal 13 in the vertical direction in the state where the railway vehicle 1 is positioned horizontally. Any structure may be used as long as the structure is such that the structure is guided through a position lower than the position. As an example, the cable 11 is connected to the display terminal 13 after passing through a position higher than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. A guide for guiding the cable 11 to be disposed through a position lower than the vertical position of one end of the cable 11 will be described. FIG. 17 shows a vehicle display device 30 having this guide. The vehicle display device 30 illustrated in FIG. 17 includes protrusions 35 and 36 that extend from the inner surface 31c of the housing 31 in the X-axis direction, instead of the protrusion 33. The protrusions 35 and 36 serve as guides. Note that FIG. 17 is a rear view of a modified example of the vehicle display device 30 in a state where the railway vehicle 1 is horizontally positioned.
　突起３５の鉛直方向下端は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。好ましくは、鉄道車両１が、水平に位置している状態で、突起３５の鉛直方向下端と端子１３ａとを結ぶ直線が水平方向となす角を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすればよい。この結果、側面３１ｂの外面が、鉄道車両１の進行方向前方を向き、かつ、鉄道車両１が、傾斜角が最大となる上り斜面に位置している状態で、突起３５の鉛直方向下端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。また側面３１ｂの外面が、鉄道車両１の進行方向後方を向き、かつ、鉄道車両１が傾斜角が最大となる下り斜面に位置している状態で、突起３５の鉛直方向下端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。 The lower end of the protrusion 35 in the vertical direction is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is positioned horizontally. Preferably, when the railway vehicle 1 is positioned horizontally, the angle formed by the straight line connecting the vertical lower end of the protrusion 35 and the terminal 13a with the horizontal direction is the inclination angle of the route on which the railway vehicle 1 travels. It should be larger than the maximum value. As a result, with the outer surface of the side surface 31b facing forward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being located on the upslope having the maximum inclination angle, the vertical lower end of the protrusion 35 is It is lower than the vertical position of one end of the cable 11 connected to the display terminal 13. Further, in a state where the outer surface of the side surface 31b faces the rear in the traveling direction of the railway vehicle 1 and the railway vehicle 1 is located on the downward slope where the inclination angle is the maximum, the vertical lower end of the projection 35 has the display terminal 13 Is lower than the vertical position of one end of the cable 11 connected to.
　また突起３６の鉛直方向上端は、鉄道車両１が水平に位置している状態で、開口３１２の鉛直方向の位置より高い。好ましくは、鉄道車両１が、水平に位置している状態で、突起３６の鉛直方向上端と端子１３ａとを結ぶ直線が水平方向となす角を、鉄道車両１が走行する路線での傾斜角の最大値より大きくすればよい。この結果、側面３１ｂの外面が、鉄道車両１の進行方向前方に向き、かつ、鉄道車両１が傾斜角が最大となる上り斜面に位置している状態で、突起３６の鉛直方向上端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高い。また側面３１ｂの外面が、鉄道車両１の進行方向後方を向き、かつ、鉄道車両１が、傾斜角が最大となる下り斜面に位置している状態で、突起３６の鉛直方向上端は、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より高い。
　なお図１７において、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置、すなわち、端子１３ａの鉛直方向の位置を一点鎖線で示す。 Further, the upper end of the protrusion 36 in the vertical direction is higher than the position of the opening 312 in the vertical direction when the railway vehicle 1 is positioned horizontally. Preferably, when the railway vehicle 1 is positioned horizontally, the angle formed by the straight line connecting the vertical upper end of the protrusion 36 and the terminal 13a with the horizontal direction is the inclination angle of the route on which the railway vehicle 1 travels. It should be larger than the maximum value. As a result, with the outer surface of the side surface 31b facing forward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being positioned on the upslope having the maximum inclination angle, the vertical upper end of the protrusion 36 is displayed. It is higher than the vertical position of one end of the cable 11 connected to the terminal 13. Further, with the outer surface of the side surface 31b facing rearward in the traveling direction of the railway vehicle 1 and the railway vehicle 1 being positioned on the descending slope having the maximum inclination angle, the vertical upper end of the protrusion 36 is It is higher than the vertical position of one end of the cable 11 connected to 13.
In FIG. 17, the vertical position of one end of the cable 11 connected to the display terminal 13, that is, the vertical position of the terminal 13a is indicated by a dashed line.
　ケーブル１１は、突起３５の鉛直方向下端に沿い、さらに突起３６の鉛直方向上端に沿って配設される。突起３５の鉛直方向下端は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い。そのため、ケーブル１１は、鉄道車両１が水平に位置している状態で、表示端末１３に接続されたケーブル１１の一端の鉛直方向の位置より低い位置を通って空間３２に配設されている。この結果、鉄道車両１が水平に位置する状態で、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 The cable 11 is arranged along the vertical lower end of the protrusion 35 and further along the vertical upper end of the protrusion 36. The vertical lower end of the protrusion 35 is lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is horizontally positioned. Therefore, the cable 11 is arranged in the space 32 through a position lower than the vertical position of one end of the cable 11 connected to the display terminal 13 in a state where the railway vehicle 1 is horizontally positioned. As a result, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a in a state where the railway vehicle 1 is positioned horizontally.
　さらに鉄道車両１が、傾斜が最大となる斜面に位置している状態で、突起３６の鉛直方向上端が、開口３１２の鉛直方向の位置より高いため、筐体３１の外側に引き出されたケーブル１１に付着した水滴がケーブル１１を伝って移動しても、突起３６の鉛直方向上端に到達できない。この結果、鉄道車両１が斜面に位置していても、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。 Further, in the state in which the railway vehicle 1 is located on the slope where the inclination is the maximum, the vertical upper end of the protrusion 36 is higher than the vertical position of the opening 312, so that the cable 11 pulled out to the outside of the housing 31. Even if the water droplets attached to the wire move along the cable 11, they cannot reach the upper end of the protrusion 36 in the vertical direction. As a result, even when the railway vehicle 1 is located on the slope, water droplets are prevented from traveling along the cable 11 and reaching the terminal 13a.
　移動防止部材の形状は、ケーブル１１に当接する位置から表示端末１３の方向にケーブル１１に付着した水滴が移動することを防止することができる形状であれば、任意である。一例として、移動防止部材は、両端が筐体１２の内面または筐体３１の内面３１ｃに固定され、Ｕ字状に折り曲げられた形状を有する棒状部材で構成されてもよい。この移動防止部材を備える車両用表示装置４０を図１８および図１９に示す。この車両用表示装置４０は、図１１に示す移動防止部材３４に代えて、両端が筐体３１の内面３１ｃに固定され、Ｕ字状に折り曲げられた形状を有する移動防止部材３７と、移動防止部材３７を内面３１ｃに固定する締結部材３８とを備える。移動防止部材３７は、ケーブル１１の一部の鉛直方向下端に当接する。また移動防止部材３７は、端子１３ａに隣接する。具体的には、移動防止部材３７は、端子１３ａから離隔した状態で、端子１３ａに可能な限り近づけて配置されることが好ましい。これにより、水滴がケーブル１１を伝って端子１３ａに到達することが防止される。
　また他の一例として、移動防止部材は、一端が筐体１２の内面または筐体３１の内面３１ｃに固定された棒状部材、ケーブル１１に巻かれたテープまたは布等で構成されてもよい。 The shape of the movement preventing member is arbitrary as long as it can prevent water droplets attached to the cable 11 from moving from the position in contact with the cable 11 toward the display terminal 13. As an example, the movement preventing member may be a rod-shaped member having both ends fixed to the inner surface of the housing 12 or the inner surface 31c of the housing 31 and having a U-shaped bent shape. A vehicle display device 40 including this movement preventing member is shown in FIGS. 18 and 19. In this vehicle display device 40, instead of the movement prevention member 34 shown in FIG. 11, both ends are fixed to the inner surface 31c of the housing 31, and the movement prevention member 37 has a shape bent in a U shape, and movement prevention. And a fastening member 38 for fixing the member 37 to the inner surface 31c. The movement preventing member 37 abuts on a lower end of the cable 11 in the vertical direction. The movement prevention member 37 is adjacent to the terminal 13a. Specifically, it is preferable that the movement preventing member 37 be arranged as close to the terminal 13a as possible in a state of being separated from the terminal 13a. This prevents water droplets from traveling along the cable 11 and reaching the terminal 13a.
As another example, the movement prevention member may be configured by a rod-shaped member whose one end is fixed to the inner surface of the housing 12 or the inner surface 31c of the housing 31, a tape or cloth wound around the cable 11, or the like.
　端子１３ａの差込口が向く方向は、Ｙ軸方向に限られない。端子１３ａは、差込口をＺ軸負方向を除く任意の方向に向けて配置可能である。 The direction in which the insertion port of the terminal 13a faces is not limited to the Y-axis direction. The terminal 13a can be arranged such that the insertion port is oriented in any direction except the Z-axis negative direction.
　車両用表示装置１０，２０，３０，４０は、ドア３の横に限られず、ケーブル１１の配線の制約によって、ケーブル１１を水平方向に引き出す必要がある場所に設置される場合に、有用である。なお車両用表示装置１０，２０，３０，４０の設置位置は、乗客が画面を視認可能な位置であれば、任意である。一例として、車両用表示装置１０，２０，３０，４０は、ドア３の上、窓の上などに設置されてもよい。 The vehicle display device 10, 20, 30, 40 is useful not only beside the door 3 but also when it is installed in a place where the cable 11 needs to be pulled out in the horizontal direction due to restrictions on the wiring of the cable 11. .. It should be noted that the vehicle display devices 10, 20, 30, 40 may be installed at any positions as long as the screens are visible to passengers. As an example, the vehicle display device 10, 20, 30, 40 may be installed on the door 3, on the window, or the like.
　車両用表示装置１０，２０，３０，４０のそれぞれに、複数のケーブル１１が接続されてもよい。この場合、ガイドは、各ケーブル１１を、鉄道車両１が水平に位置している状態で、表示端末１３に接続された一端の鉛直方向の位置より低い位置を通って配設されるよう導く。 A plurality of cables 11 may be connected to each of the vehicle display devices 10, 20, 30, 40. In this case, the guide guides each cable 11 so as to be arranged through a position lower than the vertical position of one end connected to the display terminal 13 in a state where the railcar 1 is positioned horizontally.
　鉄道車両１を構成する車両２の数は任意であり、単数であってもよい。また各車両２に搭載される車両用表示装置１０，２０，３０，４０の数は任意である。また鉄道車両１に搭載される制御装置４の数は任意である。 The number of vehicles 2 constituting the railway vehicle 1 is arbitrary and may be singular. Further, the number of vehicle display devices 10, 20, 30, 40 mounted on each vehicle 2 is arbitrary. Further, the number of control devices 4 mounted on the railway vehicle 1 is arbitrary.
