Description

Technical Field

[0001] This application relates to the technical field of assembling electronic control devices for rail trains, and more specifically, to an electronic control device mounting device for rail trains and a rail train. Background Technology

[0002] With the rapid development of high-speed rail and urban rail transit, especially the increasing prevalence of driverless technology, the onboard systems and equipment of rail trains are becoming more numerous and their electrical functions more complex in order to ensure the safe operation of rail trains. Traditional rail train electrical control devices (such as circuit breakers, relays, and terminal blocks) are typically installed in vertical electrical cabinets at the ends of the carriages. However, these end electrical cabinets are usually welded from steel or aluminum alloy square tubing, resulting in a large overall size. This not only occupies a significant amount of space at the ends of the carriages, affecting passenger capacity and space utilization, but also fails to meet the growing component installation requirements of fully automated vehicles. Particularly in driverless projects, vertical electrical cabinets are typically not installed in the driver's cab, leaving no place to install electrical control components. Summary of the Invention

[0003] In view of this, in order to solve at least one of the technical problems in the prior art, this application provides an electrical control device installation device for a rail train and a rail train, which can free up interior space in the passenger compartment to increase passenger capacity while facilitating subsequent maintenance work by maintenance personnel.

[0004] One aspect of this application provides an electrical control device mounting device for a railcar, wherein the frame of the railcar extends from the side wall to the top wall, and side rails and top rails are respectively provided on the side wall frame located on the side wall and the top wall frame located on the top wall, both of which extend along the length direction of the railcar. The electrical control device mounting device includes: a mounting base plate suitable for supporting multiple electrical control devices, the top of the mounting base plate being connected to the top rail; and two support frames respectively connected to the mounting base plate on opposite sides along the length direction of the railcar and between the side rails, and the two support frames extending along the width direction of the railcar, such that the lower edge of the mounting base plate remains parallel to and spaced from the side wall.

[0006] According to some embodiments of this application, the electrical control device mounting device for rail trains further includes: a cover, installed between the top wall frame and the side wall, and together with the top wall frame and the side wall, forming an accommodating space to accommodate the mounting base plate, and the cover is provided with a maintenance door suitable for inspecting the electrical control device.

[0007] According to some embodiments of this application, the aforementioned inspection door includes: a door body rotatably mounted about a pivot extending parallel to the vehicle length direction at the edge of an opening formed in the door body, for exposing the electrical control device by opening the door body and for inspecting the electrical control device; and a locking mechanism configured to lock the door body to the edge of the opening opposite to the pivot.

[0008] According to some embodiments of this application, the mounting substrate includes: a first region suitable for mounting circuit breakers and terminal blocks; and a second region, arranged at intervals from the first region along the vehicle length direction, suitable for mounting different types of relays, wherein the different types of relays are arranged parallel to each other at intervals along the height direction in the second region.

[0009] According to some embodiments of this application, the mounting substrate further includes a protective cover plate extending in a direction perpendicular to the plane of the mounting substrate to cover the plurality of electrical control devices, and the width of the protective cover plate above the second region is greater than the width of the protective cover plate above the first region.

[0010] According to some embodiments of this application, the mounting device for electrical control devices of a railcar further includes: two connecting plates, respectively disposed on opposite sides of the protective cover along the length of the vehicle, with one end of the two connecting plates connected to the top of the protective cover and the other end of the two connecting plates connected to the top rail, so as to fix the mounting base plate to the top rail.

[0011] According to some embodiments of this application, the mounting device for electrical control devices of a railcar further includes: multiple sets of limiting components connected between the connecting plate and the top rail, and between the second plate and the side rail, to limit the position of the mounting base plate in the frame. Each set of the limiting components includes: a bolt head; a slider disposed between the bolt head and the top rail, or between the bolt head and the side rail, and the slider slidingly engaging with the top rail or the side rail; a screw, one end of which is connected to the bolt head, and the other end of which passes through and extends out from the connecting plate or the second plate; and a fixing member cooperating with the screw to fix the connecting plate to the top rail or the support frame to the side rail.

[0012] According to some embodiments of this application, the mounting substrate further includes: a plurality of wire binding frames disposed between the terminal block and the relay, and between different types of the relays, to facilitate the bundling of wire harnesses of the terminal block and the relays.

[0013] According to some embodiments of another aspect of this application, a rail train is also provided, comprising: a frame extending from the side wall to the top wall of the rail train, wherein side rails and top rails are respectively provided on the side wall frame located on the side wall and the top wall frame located on the top wall, and both the side rails and the top rails extend along the length direction of the rail train; and the aforementioned electrical control device mounting device for the rail train is mounted on the frame.

The mounting base is connected to a top rail at its top and two support frames are connected to side rails, allowing the electrical control device mounting device to be fixed in the corner gap area between the side wall frame and the top wall frame. This utilizes the existing sliding grooves of the rail train body for installation without additional drilling, maintaining the integrity of the car body structure. The electrical control devices are moved from the driver's cab's vertical electrical cabinet to this area, freeing up interior space in the passenger compartment to increase passenger capacity. Because the top and side rails extend along the length of the train, the mounting base and support frames can slide along the sliding grooves to adjust their position and lock, allowing the electrical control devices to flexibly adapt to the control needs of different positions on the rail train. Furthermore, the two support frames extend along the width of the rail train, ensuring that the lower edge of the mounting base remains parallel to and spaced from the side wall. The front of the mounting base faces the maintenance personnel, facilitating subsequent maintenance work. Attached Figure Description

[0064] The embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this application. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of this application for ease of explanation. However, it will be apparent that one or more embodiments may be implemented without these specific details. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0065] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0066] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0067] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0068] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0069] Current railcar installation methods often use bolts or other connectors to fix independent frame structures to the side walls or roof of the car body. This installation method is not flexible or convenient enough and fails to fully utilize the structural characteristics of the railcar body profiles. Furthermore, existing installation structures are lacking in wire harness organization and modular design, and their decentralized layout is insufficient, easily leading to wire harness concentration at the ends, which is detrimental to railcar wiring and subsequent maintenance.

[0070] Figure 1 This is a side view of an electrical control device mounting device for a railcar, according to an illustrative embodiment of the present application, mounted on a frame.

[0071] Embodiments of this application provide an electrical control device mounting device 100 for rail trains, such as... Figure 1As shown, the frame 2 of the rail train extends from the side wall 1 to the top wall. Side rails 23 and top rails 24 are respectively installed on the side wall frame 21 located on the side wall 1 and the top wall frame 22 located on the top wall. Both side rails 23 and top rails 24 extend along the length of the rail train. The electrical control device mounting device 100 includes a mounting base 3 and two support frames 5. The mounting base 3 is suitable for supporting multiple electrical control devices 4, and the top of the mounting base 3 is connected to the top rail 24. The two support frames 5 are respectively connected to the side rails 23 on opposite sides of the mounting base 3 along the length of the rail train, and the two support frames 5 extend along the width of the rail train, so that the lower edge of the mounting base 3 remains parallel to and spaced from the side wall 1.

[0072] In some illustrative embodiments, the frame 2 of the railcar extends from the side wall 1 to the top wall. Side rails 23 and top rails 24 are respectively installed on the side wall frame 21 located on the side wall 1 and the top wall frame 22 located on the top wall. It should be noted that the side rails 23 and top rails 24 utilize the existing structural features of the railcar body profile, namely, the body profile has grooves arranged along the length of the train, and both the side rails 23 and top rails 24 extend along the length of the railcar. This design eliminates the need for additional drilling or welding of mounting foundations on the body; installation can be performed directly using the existing grooves on the body, and it also facilitates the movement and adjustment of the electrical control device mounting device 100 along the length of the train.

[0073] In this implementation, the mounting base 3 is connected to the top rail 24, and the two support frames 5 are connected to the side rails 23. This allows the electrical control device mounting device 100 to be fixed in the corner gap area between the side wall frame 21 and the top wall frame 22. The existing tracks on the train body are used for installation without additional drilling, maintaining the integrity of the train body structure. The electrical control devices 4 are moved from the driver's cab's vertical electrical cabinet to this area, freeing up interior space to increase passenger capacity. Because the top rail 24 and side rails 23 extend along the length of the train, the mounting base 3 and support frames 5 can slide along the tracks to adjust their position and lock, allowing the electrical control devices 4 to flexibly adapt to the control needs of different positions on the train. Furthermore, the two support frames 5 extend along the width of the train, ensuring that the lower edge of the mounting base 3 is parallel to and spaced from the side wall 1. The front of the mounting base 3 faces the maintenance personnel, facilitating subsequent maintenance work.

[0074] Figure 2 This is a perspective view of an electrical control device mounting device for a rail train according to an illustrative embodiment of this application. Figure 3 yes Figure 2 A magnified view of a section at point B.

[0075] According to embodiments of this application, such as Figure 2 and Figure 3As shown, each support frame 5 includes a first plate, a transition plate 51, and a second plate 52. The first plate is mounted on the back side of the mounting base 3 (i.e., the side facing the side wall 1 of the train body). The transition plate 51 extends perpendicularly to the mounting base 3 from one side of the first plate. The second plate 52 extends parallel to the mounting base 3 from the side of the transition plate 51 that is away from the first plate (i.e., the direction of extension of the second plate 52 is opposite to the direction of extension of the first plate from the transition plate 51), and there is a gap between the plane of the second plate and the back side of the mounting base 3, such that there is an angle of 0° to 20° between the mounting base 3 and the side wall 1.

[0076] As an example, the included angle between the mounting base 3 and the side wall 1 can be selected as 0°, 5°, 10°, 15°, 20° or a range of any two of the above values.

[0077] In this embodiment, the first plate is fixed to the back of the mounting base 3, forming a surface contact connection between the support frame 5 and the mounting base 3, thus improving connection rigidity and stability. A transition plate 51 extends perpendicularly to the mounting base 3 from one side of the first plate, changing the force direction of the support frame 5 from the plane of the mounting base to a direction perpendicular to the side wall 1. This allows the support frame 5 to span the gap between the lower edge of the mounting base 3 and the side wall 1 and transfer the load to the side rail 23. A second plate 52 extends parallel to the mounting base 3 from the transition plate 51 and is fixed to the side of the side rail, forming a Z-shaped cross-section for the support frame 5. The gap between the second plate 52 and the back of the mounting base 3 provides a continuous routing space for the wire harness along the vehicle length, preventing the wire harness from being squeezed or blocked at the support frame 5. By adjusting the width of the transition plate 51, the angle between the mounting base plate 3 and the side wall 1 is controlled between 0° and 20°, so that the lower edge of the mounting base plate 3 is tilted towards the inside of the vehicle, thereby improving the visibility and reach of the maintenance personnel, and making it easier to inspect and maintain the electrical control devices 4 on the mounting base plate 3.

[0078] Figure 4 This is a side view of the frame and cover according to an illustrative embodiment of the present application.

[0079] According to embodiments of this application, such as Figure 1 and Figure 4 As shown, the electrical control device mounting device 100 for rail trains also includes a cover 8, which is installed between the top wall frame 22 and the side wall 1, and together with the top wall frame 22 and the side wall 1, forms an accommodating space to accommodate the mounting base plate 3. The cover 8 is provided with an inspection door for inspecting and maintaining the electrical control device 4.

[0080] In some illustrative embodiments, the enclosure 8 is formed by a top plate 81, side plates, and end plates, and is installed between the top wall frame 22 and the side wall 1. The top plate 81 of the enclosure 8 is fixedly connected to the top wall frame, the side plates of the enclosure 8 are fixedly connected to the side wall 1, and the two end plates of the enclosure 8 respectively enclose the two ends of the accommodating space along the length of the vehicle. The enclosure 8, the top wall frame 22, and the side wall 1 together form a closed accommodating space, within which the mounting base plate 3 and the support frame 5 are accommodated. An inspection door is provided on the side of the enclosure 8 facing the passenger compartment. The inspection door can be opened or closed, exposing the electrical control devices 4 carried on the front of the mounting base plate 3 when the inspection door is open.

[0081] In this implementation, the enclosure 8, together with the top wall frame 22 and side walls 1, forms a closed accommodating space, physically isolating the mounting base plate 3 and electrical control devices 4 from the passenger compartment area. This prevents passengers from touching live components and prevents dust and foreign objects from entering the mounting area of ​​the electrical control devices 4, thereby ensuring operational safety and extending the service life of the devices. The two end plates of the enclosure 8 respectively seal both ends of the accommodating space along the vehicle's length, shielding and protecting the cable connection paths between adjacent mounting base plates 3, preventing exposed and damaged cables. By providing an access door on the side of the enclosure 8 facing the passenger compartment, maintenance personnel can open the access door to access the electrical control devices 4 without disassembling the entire enclosure structure, shortening maintenance time.

[0082] According to embodiments of this application, such as Figure 4 As shown, the access door includes a door body 82 and a locking mechanism 84. The door body 82 is rotatably mounted about a pivot 83 extending parallel to the length of the vehicle to the edge of an opening formed in the door body 82, allowing access to the electrical control device 4 by exposing it through the door body 82. The locking mechanism 84 is configured to lock the door body 82 to the edge of the opening opposite to the pivot 83.

[0083] In some illustrative embodiments, the opening is defined by the lower edge of the top plate 81 of the cover 8 and the side plate.

[0084] In some illustrative embodiments, pivot 83 extends parallel to the vehicle length and is mounted on the upper edge of the opening. Door 82 is hinged to the lower edge of the roof panel 81 via pivot 83. When door 82 rotates downwards about pivot 83 to the closed position under its own weight, door 82 covers the opening. When door 82 is flipped upwards about pivot 83 to the open position under external force, the opening is exposed, and the electrical control devices 4 mounted on the mounting base 3 are visible and accessible from the passenger compartment side. Locking mechanism 84 is mounted on the lower edge of door 82 to lock door 82 to the side panel. Locking mechanism 84 is a manually operable rotary lock or a push-button spring lock.

[0085] In some alternative embodiments, pivot 83 may also be mounted on the lower edge of the opening, and door 82 flips downward about pivot 83 to open, with door 82 resting against the side wall after opening. Locking mechanism 84 is mounted on the upper edge of door 82 to lock door 82 to the lower edge of top plate 81.

[0086] In this implementation, by setting the pivot 83 parallel to the length of the vehicle, the opening and closing trajectory of the door lies within the plane of the width of the vehicle. When the door opens, it does not extend significantly into the depth of the passenger compartment, reducing the occupancy of the passenger compartment passageway and facilitating maintenance operations in the narrow passageways of the railcar. By setting the pivot 83 at the upper edge of the opening and allowing the door 82 to flip upwards, the locking mechanism 84 locks the door 82 to the edge of the opening opposite to the pivot 83. This prevents the door 82 from slapping or making abnormal noises due to vibrations from the railcar, ensuring the structural stability of the door 82 after closing and its sealing performance for the accommodating space.

[0087] Figure 5 This is a first-view side view of an electrical control device mounting device for a railcar according to an illustrative embodiment of this application. Figure 6 This is a second-view side view of an electrical control device mounting device for a railcar according to an illustrative embodiment of this application. Figure 7 yes Figure 6 A magnified view of a portion of point A in the middle.

[0088] According to embodiments of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the mounting base plate 3 includes a first region 32 and a second region 33. The first region 32 is suitable for mounting a circuit breaker 41 and a terminal block 42. The second region 33 is arranged at intervals from the first region 32 along the length of the vehicle, and the second region 33 is suitable for mounting different types of relays 43. The different types of relays 43 are arranged parallel to each other at intervals along the height direction in the second region 33.

[0089] In some illustrative embodiments, the terminal block 42 is mounted on the first region 32 of the mounting base plate 3 via a guide rail 35. The guide rail 35 extends parallel to the vehicle length direction, and the terminal block 42 can slide along the guide rail 35 to adjust its position. After the terminal block 42 is installed in place on the guide rail 35, the relative position of the terminal block 42 and the guide rail 35 is locked by the locking screws or end stops provided with the terminal block 42.

[0090] In some illustrative embodiments, different types of relays 43 are arranged in layers along the height direction, with each layer of relays 43 arranged sequentially along the length of the vehicle, and the relays 43 in each layer are kept parallel to each other.

[0091] In some illustrative embodiments, the electrical control device 4 can be composed of different numbers of relays 43, terminal blocks 42, and circuit breakers 41 according to the actual control requirements of the rail train, forming a modular structural combination. This modular installation structure can be freely combined to meet the control requirements of the rail train. For example, the arrangement of relays 43 can be emphasized, or the arrangement of circuit breakers 41 or terminal blocks 42 can be emphasized.

[0092] In this implementation, by installing the circuit breaker 41 and terminal block 42 in the first area 32 and the relay 43 in the second area 33, the high-voltage switching devices and low-voltage control devices are spatially partitioned. This avoids electromagnetic interference generated by the switching of the circuit breaker 41 affecting the control signal of the relay 43 and reduces cross-coupling between cables of different voltage levels. The first area 32 and the second area 33 are spaced apart along the vehicle length, forming a vertical gap between them. This gap provides a natural separation channel for cross-area wiring harnesses, allowing high-voltage and low-voltage harnesses to enter the binding holes independently, reducing the risk of insulation wear due to friction after binding. The relays 43 are arranged in parallel layers along the height, creating a vertical airflow gap between each layer. This facilitates heat dissipation from the relay coils and contacts during operation, preventing heat accumulation between layers. Simultaneously, the layered arrangement ensures that the status indicator lights and markings of each relay 43 are within unobstructed visibility, facilitating rapid identification of faulty devices and shortening maintenance and location time.

[0093] Figure 8 This is a third-view side view of an electrical control device mounting device for a railcar according to an illustrative embodiment of this application.

[0094] According to embodiments of this application, such as Figure 6 and Figure 8 As shown, the mounting substrate 3 also includes a protective cover plate 31. The protective cover plate 31 extends in a direction perpendicular to the plane of the mounting substrate 3 to cover the multiple electrical control devices 4, and the width of the protective cover plate 31 located above the second region 33 is greater than the width of the protective cover plate 31 located above the first region 32.

[0095] In some illustrative embodiments, the protective cover 31 may be integrally formed with the mounting base 3, or fixed to the upper edge of the mounting base 3 by fasteners. The protective cover 31 extends from the side of the mounting base 3 that carries the electrical control device 4 in a direction perpendicular to the mounting base 3, covering the electrical control device 4 mounted in the first region 32 and the second region 33. The extension width of the protective cover 31 above the second region 33 is greater than the extension width of the protective cover 31 above the first region 32.

[0096] In this implementation, a protective cover 31 extends perpendicularly to the plane of the mounting base 3 and covers the multiple electrical control devices 4, forming a shielding surface. This prevents condensate, dust, or foreign objects falling from the top wall frame 22 from directly intruding into the terminals and wiring parts of the electrical control devices 4, thereby reducing the risk of short circuits caused by foreign objects and poor contact caused by dust accumulation. Because the width of the protective cover 31 above the second region 33 is greater than the width of the protective cover 31 above the first region 32, different types of relays 43 and their coil terminals within the second region 33 receive deeper shielding. This compensates for the structural difference in size between the relays 43 and the circuit breaker, which have smaller external dimensions and more concentrated exposed terminal areas, thus balancing the uniformity of protection for the electrical control devices 4 in different regions.

[0097] According to embodiments of this application, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the mounting device for the electrical control components of the railcar also includes two connecting plates 6. The two connecting plates 6 are respectively disposed on opposite sides of the protective cover 31 along the length of the vehicle, and one end of the two connecting plates 6 is connected to the top of the protective cover 31, and the other end of the two connecting plates 6 is connected to the top rail 24 to fix the mounting base plate 3 to the top rail 24.

[0098] In this implementation, the top of the protective cover plate 31 is directly connected to the top rail 24 via the connecting plate 6, so that the top of the protective cover plate 31 is suspended and fixed to the top rail 24 through the connecting plate 6, forming an auxiliary force transmission path from the mounting base plate 3 through the protective cover plate 31 to the top rail 24. This distributes the vertical load between the top of the mounting base plate 3 and the top rail 24, improving the suspension reliability of the mounting base plate 3 under the vibration conditions of the rail train operation. By setting two connecting plates 6 on both sides of the protective cover plate 31 along the length of the vehicle, symmetrical suspension constraints are established at both ends of the protective cover plate 31, limiting the tendency of the protective cover plate 31 to move along the length of the vehicle due to the inertial force of the rail train's acceleration or deceleration, and ensuring that the mounting base plate 3 is subjected to balanced forces at both ends along the length of the vehicle.

[0099] According to embodiments of this application, such as Figure 1 , Figure 5 and Figure 8 As shown, the mounting device for the electrical control components of the railcar also includes multiple sets of limiting components 7, which are connected between the connecting plate 6 and the top rail 24, and between the second plate 52 and the side rail 23, to limit the position of the mounting base plate 3 on the frame 2.

[0100] According to an embodiment of this application, each set of limiting components 7 includes a first bolt head 71, a first slider 77, a first screw 72, and a first fixing member 73. The first slider 77 is disposed between the first bolt head 71 and the top rail 24, and the first slider 77 is slidably engaged with the top rail 24. One end of the first screw 72 is connected to the first bolt head 71, and the other end of the first screw 72 passes through and extends out of the connecting plate 6. The first fixing member 73 engages with the first screw 72 to fix the connecting plate 6 to the top rail 24.

[0101] In some illustrative embodiments, a first slider 77 is housed within a groove of the top rail 24 and slides within the groove, the width of the first slider 77 being greater than the width of the groove opening. A first bolt head 71 is located inside the top rail 24 and abuts against the surface of the top rail 24. One end of a first screw 72 is connected to the first bolt head 71, the first screw 72 passes through the central hole of the first slider 77, and the other end of the first screw 72 passes through a through hole on the connecting plate 6 and extends outward. A first fixing member 73 is threadedly engaged with the other end of the first screw 72, and tightening the first fixing member 73 presses the connecting plate 6 against the surface of the top rail 24.

[0102] As an example, the first fastener 73 can be a combination of a self-locking nut or a spring washer and a flat nut.

[0103] In this implementation, the connecting plate 6 can be freely adjusted along the length of the vehicle in the unlocked state by sliding the first slider 77 with the groove of the top rail 24, thereby adjusting the positioning of the mounting base plate. Tightening the first fixing member 73 generates axial tension in the first screw 72, pressing the connecting plate 6 against the top rail 24 to form a surface contact friction lock. This dual constraint of the connecting plate 6's displacement in both the length and height directions from inside the groove and on the rail surface ensures the reliability of the mounting base plate 3's positioning in the vibration environment of the railway train. The self-locking thread characteristics of the first fixing member 73 and the first screw 72 ensure that the threaded pair remains stationary without continuous external force, preventing preload decay due to vibration and thus maintaining a lasting constraint on the mounting base plate 3.

[0104] According to an embodiment of this application, each set of limiting components 7 includes a second bolt head 74, a second slider 78, a second screw 75, and a second fixing member 76. The second slider 78 is disposed between the second bolt head 74 and the side rail 23, and the second slider 78 is slidably engaged with the side rail 23. One end of the second screw 75 is connected to the second bolt head 74, and the other end of the second screw 75 passes through and extends out of the second plate 52. The second fixing member 76 cooperates with the second screw 75 to fix the support frame 5 to the side rail 23.

[0105] In some illustrative embodiments, the second slider 78 is housed within and slides within a groove of the side rail 23, with the width of the second slider 78 being greater than the width of the groove opening. The second bolt head 74 is located inside the side rail 23 and abuts against its surface. One end of the second screw 75 is connected to the second bolt head 74, and the second screw 75 passes through the central hole of the second slider 78. The other end of the second screw 75 passes through a through hole in the second plate 52 of the support frame 5 and extends outward. The second fixing member 76 is threadedly engaged with the other end of the second screw 75, and tightening the second fixing member 76 presses the second plate 52 against the surface of the side rail 23.

[0106] As an example, the second fastener 76 can be a combination of a self-locking nut or a spring washer and a flat nut.

[0107] In this embodiment, the second slider 78 slides into the groove of the side rail 23, allowing the support frame 5, along with the mounting base 3, to be adjusted in position along the vehicle length when not locked. Tightening the second fixing member 76 subjects the second screw 75 to axial tension, pressing the second plate 52 against the side rail 23 to form a surface contact lock. This dual constraint of the second plate 52's displacement in both the vehicle length and width directions, from both inside the groove and on the side rail surface, fixes the support frame 5 to the side rail 23 and restricts the spatial position of the mounting base 3. The self-locking thread of the second fixing member 76 and the second screw 75 maintains the preload without attenuation under the vibration conditions of the train operation, ensuring the long-term reliability of the connection between the support frame 5 and the side rail 23.

[0108] According to embodiments of this application, such as Figure 5 As shown, the mounting base plate 3 also includes multiple wire binding brackets 36, which are disposed between the terminal block 42 and the relay 43, as well as between different types of relays 43, to facilitate the bundling of wire harnesses between the terminal block 42 and the relay 43.

[0109] In some illustrative embodiments, a plurality of wire tie brackets 36 are mounted on the side of the mounting base 3 that carries the electrical control device 4. The wire tie brackets 36 extend outward from the surface of the mounting base 3, forming a support structure that extends perpendicularly to the surface of the mounting base 3.

[0110] In this implementation, by placing the wire binding bracket 36 between the terminal block 42 and the relay 43, the high-voltage wire harness from the terminal block 42 and the low-voltage wire harness from the relay 43 are physically separated along their paths, each bound to its corresponding wire binding bracket 36. This avoids electromagnetic interference coupling caused by mixing high-voltage and low-voltage wire harnesses. By placing the wire binding bracket 36 between different types of relays 43, the wire harnesses of relays 43 with different control functions are independently bound and fixed in layers or groups, making the wire harness routing path clearly identifiable. This facilitates quick tracing of the cable source and destination during fault diagnosis. The bracket structure extending from the wire binding bracket 36 provides the binding attachment position, ensuring that the binding force of the wire harness is borne by the wire binding bracket 36 and not directly applied to the terminals of the relay 43 or the wiring terminals of the circuit breaker 41. This prevents the pulling force of the wire harness under the vibration environment of the rail train from causing the terminals to loosen or have poor contact, thereby improving the reliability of the electrical connection.

[0111] According to embodiments of this application, such as Figure 5 As shown, a plurality of wire-binding holes 37 are spaced apart on the edge of the mounting substrate 3 to allow wires to pass through.

[0112] In this implementation, the multiple binding holes 37 allow the wire harness to pass through the mounting substrate 3 at multiple points along its edge. This guides the wire harness from the bearing surface of the mounting substrate 3 to the gap between the back of the mounting substrate 3 and the side wall 1, preventing the wire harness from accumulating on the bearing surface of the mounting substrate 3 and obstructing the operating surface and markings of the electrical control device 4. By arranging the multiple binding holes 37 at intervals, each wire harness can pass through different binding holes 37 according to signal type or direction, achieving physical separation of the wire harness at the penetration point. This facilitates the wire harnesses to converge into corresponding routing channels on the back of the mounting substrate 3, thereby improving the organization of the wire harness installation. The multiple binding holes 37 not only reduce the overall weight of the mounting substrate 3 but also achieve wire harness bundling and neatness.

[0113] According to embodiments of this application, such as Figure 5 As shown, the mounting base 3 also includes a grounding base 34.

[0114] In some illustrative embodiments, the grounding base 34 can be a terminal block or terminal block made of conductive metal, fixedly installed on the surface or edge of the mounting base 3. Multiple grounding terminals can be provided on the grounding base 34, each grounding terminal allowing the grounding wire of one or more electrical control devices 4 to be connected and locked in place.

[0115] In this implementation, by setting a grounding base 34 on the mounting base 3, the grounding wires of the dispersed electrical control devices 4 such as relays 43 and circuit breakers 41 are brought together to the same grounding point, avoiding the grounding wires of each electrical control device 4 being scattered and connected to different positions on the train body, thus preventing grounding loops or potential differences, and ensuring the uniformity of the reference potential of each electrical control device 4.

[0116] According to another embodiment of this application, a rail train is provided, such as... Figure 1 As shown, the railcar includes a frame 2 and the aforementioned mounting device 100 for the railcar's electrical control components. The frame 2 extends from the side wall 1 of the railcar to the top wall. Side rails 23 and top rails 24 are respectively installed on the side wall frame 21 located on the side wall 1 and the top wall frame 22 located on the top wall, both extending along the length of the railcar. The mounting device 100 for the railcar's electrical control components is mounted on the frame 2.

[0117] In this implementation, the electrical control device mounting device 100 is installed in the corner gap between the side wall 1 and the top wall, and fixed using the existing profile grooves of the train body without the need for additional drilling into the car body frame, thus maintaining the integrity and load-bearing capacity of the car body structure. Furthermore, the lower edge of the mounting base plate 3 is parallel to and spaced from the side wall 1, with the front of the mounting base plate 3 facing the maintenance personnel, facilitating subsequent maintenance work. With the side rails 23 and top rails 24 extending along the length of the train, the electrical control device mounting device 100 can be adjusted and locked along the grooves, adapting to the control point distribution requirements of different train formations or different passenger compartment sections, enabling flexible configuration of the distributed control logic in spatial arrangement. When the cover 8 is closed, it covers the electrical control device mounting device 100, completely isolating and shielding the electrical control devices 4 from the passenger compartment area, preventing passengers from contacting live parts and dust intrusion, while maintaining the integrity and aesthetics of the passenger compartment interior decoration. When the door 82 is opened, it rotates around the pivot 83 to expose the electrical control device installation device 100. Maintenance personnel can directly access the electrical control device 4 from the passenger compartment side to perform testing and replacement operations without disassembling the entire structure of the passenger compartment interior panel, thus shortening maintenance time and reducing maintenance costs.

[0118] Figure 9 This is a side view showing the arrangement of the electrical control device mounting device in a rail train according to an illustrative embodiment of this application.

[0119] According to embodiments of this application, such as Figure 1 and Figure 9As shown, the rail train also includes multiple electrical control device mounting devices 100, which are arranged on both sides of the rail train in the width direction. The multiple electrical control device mounting devices 100 located on the same side are spaced apart and arranged above the side wall 1 of the rail train.

[0120] In some illustrative embodiments, multiple electronic control device mounting devices 100 are arranged above each of the two side walls 1 in the width direction of the rail train, for example... Figure 9 Positions a, b, c, and d are specified in the diagram. Multiple electronic control device mounting devices 100 on the same side are arranged sequentially along the length of the vehicle, with a set spacing maintained between adjacent electronic control device mounting devices 100. The spacing is determined according to the distribution requirements of the rail train control zones.

[0121] In this implementation, by arranging the electrical control device mounting devices 100 on both sides of the vehicle width direction, the control devices on both sides can manage the load equipment on the same side nearby, shortening the routing distance of the control cables from the control devices to the execution terminals, and reducing cable resistance voltage drop and signal attenuation. By having multiple electrical control device mounting devices 100 spaced apart along the length of the vehicle on the upper part of the side wall 1, the entire vehicle control circuit is segmented and distributed along the length of the railcar, allowing the control devices of each passenger compartment section or functional zone to be physically independently distributed. In the event of a single section failure, only the electrical control device mounting device 100 corresponding to that section needs to be repaired, without affecting the normal operation of the control circuits of other sections. Since each electrical control device mounting device 100 is independently fixed to the top rail 24 and the side rail 23 and can be independently adjusted along the slide rail, the spacing between adjacent devices can be flexibly adjusted according to the difference in the number of relays and circuit breakers in each control zone during the overall layout stage of the railcar, adapting to the differentiated requirements of control point distribution for different vehicle models or different train formations.

Although various embodiments have been described above, this does not mean that the measures in the various embodiments cannot be used advantageously in combination.
