Detailed implementation manners

[0035] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further describes the exemplary embodiments of the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] Figure 1 It is a schematic structural diagram of a rail vehicle provided by the prior art. Figure 2 is Figure 1 the enlarged view of part A in Figure 1 and Figure 2 As shown, in the prior art, the electrical cabinet is arranged in the driver's cab, and its volume is relatively large, occupying a large space in the driver's cab, making the activity space in the driver's cab narrow and the comfort of the working environment not high.

[0037] In the process of implementing the present application, the inventors found that it is an urgent problem to provide a double-layer partition wall and a rail vehicle that can reduce the volume of the control box, increase the activity space in the driver's cab, reasonably arrange the electrical components in the driver's cab, reasonably plan the cable path, and facilitate separate maintenance.

[0038] Figure 3 It is a schematic structural diagram of the double-layer partition wall provided by the embodiment of the present application. Figure 4 It is an exploded view of the double-layer partition wall provided by the embodiment of the present application. As shown in Figure 3 and Figure 4 shown, in view of the above problems, in the embodiment of the present application, a double-layer partition wall is provided, which is arranged between the driver's cab 1 and the passenger compartment 2 of the rail vehicle. The double-layer partition wall includes a driver's cab partition wall 10 and a passenger compartment partition wall 20 arranged at intervals. An accommodation cavity 30 is formed between the driver's cab partition wall 10 and the passenger compartment partition wall 20. The double-layer partition wall further includes a control box 40. A first through hole 101 is provided on the driver's cab partition wall 10. The back of the control box 40 penetrates through the first through hole 101 and extends into the accommodation cavity 30, and there is a gap between the back of the control box 40 and the passenger compartment partition wall 20.

[0039] In the embodiment of the present application, the control box is arranged on the double-layer partition wall, which improves the utilization rate of the accommodation cavity inside the double-layer partition wall. The back of the control box extends into the accommodation cavity, which is not only beautiful, but also can effectively reduce the volume of the control box in the driver's cab, increase the activity space in the driver's cab, and improve the comfort of the working environment in the driver's cab.

[0040] Figure 5 It is a schematic diagram of the internal structure of the control box of the double-layer partition wall provided by the embodiment of the present application. As Figure 5 shown, further, the control box 40 includes a housing 401 with an opening at the front. A surrounding extension 4011 extends around the opening of the housing 401. The control box 40 is connected to the side of the driver's cab partition wall 10 close to the driver's cab 1 through the extension 4011; a front panel 402 is connected to the opening of the housing 401. Specifically, a plurality of first threaded holes are uniformly arranged on the extension 4011, and the control box can be firmly connected to the driver's cab partition wall through the first bolts and the first threaded holes.

[0041] Furthermore, the interior of the control box 40 includes a terminal block assembly 4031, a switch assembly 4032, and a circuit breaker 4033; the terminal block assembly 4031 and the circuit breaker 4033 are respectively installed inside the control box 40 through a first guide rail 4034 and a second guide rail 4035; the switch assembly 4032 includes at least one switch button 40321, and a second through hole 4021 is arranged at a position on the front panel 402 corresponding to the switch button 40321. The switch button 40321 extends into the interior of the driver's cab 1 after passing through the second through hole 4021. Specifically, the structure in which the terminal block assembly, the switch assembly, and the circuit breaker assembly are arranged in sequence from top to bottom inside the control box can make the internal wiring of the control box more concise and beautiful, optimize the wiring path of the cables, facilitate the operation and troubleshooting of the staff, and at the same time solve the problem that the connection cables of the switch assembly are too long to be fixed. The interior of the control box is suitable for different types of terminal block assemblies, switch assemblies, and circuit breakers, and has a wide range of applications.

[0042] Figure 6 It is the internal circuit diagram of the control box of the double-layer partition wall provided by the embodiment of the present application. As Figure 6 shown, specifically, the terminal block assembly is used to connect the control box to other electrical components in the driver's cab. More specifically, the terminal block assembly 4031 includes a first terminal block and a second terminal block. The first terminal block is electrically connected to the circuit breaker 4033, and the second terminal block is electrically connected to the electrical components in the driver's cab; both the first terminal block and the second terminal block are electrically connected to the switch assembly 4032.

[0043] Figure 7 It is the side sectional view of the double-layer partition wall provided by the embodiment of the present application. Figure 8 It is the inner side view of the driver's cab partition wall of the double-layer partition wall provided by the embodiment of the present application. As Figure 7 andFigure 8 As shown, further, a first wire threading hole 4012 is provided at the top of the housing 401; a wire conduit 102 is provided on one side of the cab partition wall 10 close to the passenger compartment partition wall 20. One end of the wire conduit 102 penetrates through the first wire threading hole 4012 and extends into the interior of the housing 401, so that the wire harness in the cab 1 extends into the interior of the control box 40 after passing through the wire conduit 102 and the first wire threading hole 4012 in sequence. Further, the outer diameter of the wire harness is smaller than the inner diameter of the wire conduit 102. According to the requirements of EN50343, the cross-sectional area of the wire harness should not be greater than 60% of the cross-sectional area of the wire conduit. The wires are bundled into a neat and compact wire harness before entering the double partition wall, and then extend into the interior of the control box through the wire conduit and the first wire threading hole. After extending into the interior of the control box, the wires are electrically connected to the terminal block assembly in the control box. The setting of the wire conduit not only makes the wires more neat in the accommodation cavity, avoiding the loosening and damage of the wires caused by rubbing against other components, but also effectively solves the problem of narrow accommodation space and difficult wiring in the double partition wall.

[0044] Further, a protective cover 103 is provided on one side of the cab partition wall 10 close to the passenger compartment partition wall 20. The protective cover 103 is adapted to the part of the control box 40 extending into the accommodation cavity 30, so that the protective cover 103 completely wraps the part of the outer wall of the control box 40 extending into the accommodation cavity 30. Further protect the control box and the wires inside it to prevent rubbing against other components in the double partition wall. Specifically, a flanging part is provided around the protective cover, and a plurality of second threaded holes are uniformly provided on the flanging part. The protective cover can be connected to the cab partition wall through the second bolts and the second threaded holes. Further, heat dissipation holes 1031 are uniformly provided on the protective cover 103. Specifically, the heat dissipation holes are provided at the places where the protective cover is close to the side wall and the back of the control box. The setting of the heat dissipation holes can not only play a role in dissipating heat from the control box, but also meet the requirement of weight reduction while achieving the protection effect.

[0045] Specifically, a second wire threading hole is provided at the position of the top of the protective cover 103 corresponding to the first wire threading hole 4012, so that the wire conduit can penetrate through the second wire threading hole and the first wire threading hole in sequence. The protective cover protects both the wire outlet of the wire conduit and the control box, avoiding rubbing between other equipment in the accommodation cavity and the wires and the control box.

[0046] Figure 9 It is an exploded view of the control box of the double partition wall provided by the embodiment of the present application. Figure 10 It is a schematic diagram of the open state of the circuit breaker observation board of the double partition wall provided by the embodiment of the present application. Figure 11 It is a schematic diagram of the disassembly structure of the circuit breaker guard plate of the double partition wall provided by the embodiment of the present application, as Figure 9 、 Figure 10 and Figure 11As shown in the figure, further, a third through hole 4022 is provided at a position on the front panel 402 corresponding to the circuit breaker 4033; a circuit breaker observation plate 4024 is rotatably connected to the outside of the front panel 402 at a position corresponding to the third through hole 4022; specifically, the circuit breaker observation plate is a PC board with a transparency of 100%, the top of the circuit breaker observation plate 4024 is rotatably connected to the outside of the front panel 402 through a rotating shaft, and the bottom of the circuit breaker observation plate 4024 is connected to the outside of the front panel through a quick-release lock. Using a transparent circuit breaker observation plate enables the staff to check the working status of the circuit breaker at any time. When it is necessary to operate the circuit breaker in an emergency, only a screwdriver needs to be used to rotate the quick-release lock to open the circuit breaker observation plate. The circuit breaker 4033 includes a wiring part, and a circuit breaker guard plate 4025 is provided at a position on the third through hole 4022 corresponding to the wiring part. The function of the circuit breaker guard plate is to protect the wiring part and cables of the circuit breaker. When overhauling or replacing the circuit breaker under power-off conditions, the circuit breaker guard plate can be disassembled, and it is not necessary to disassemble the entire front panel, which is convenient for local overhaul, more flexible, safe and reliable.

[0047] Figure 12 Schematic diagram of the disassembly structure of the terminal block assembly guard plate of the double-layer partition wall provided by the embodiment of the present application, as Figure 12 shown, specifically, a fourth through hole is provided at a position on the front panel 402 corresponding to the terminal block assembly 4031, and a terminal block assembly guard plate 4023 is connected to the front panel 402 at a position corresponding to the fourth through hole. The setting of the terminal block assembly guard plate can facilitate separate maintenance when the terminal block assembly fails, and the entire front panel does not need to be removed to complete the maintenance.

[0048] Specifically, only when it is necessary to test or overhaul the switch assembly, the front panel needs to be removed.

The control box can be applied to a double-layer partition wall with a movable inner end door, and the use of the movable inner end door will not cause scratches to the inside of the control box. When the movable inner end door is opened, the movable inner end door will contract in the accommodation cavity to connect the driver's cab and the passenger compartment; when the movable inner end door is closed, the movable inner end door will extend out of the accommodation cavity to separate the driver's cab and the passenger compartment.

[0050] Specifically, when installing an orbital vehicle, it is necessary to install the passenger compartment partition wall, the movable inner end door, the driver's cab partition wall, the connection between the cable and the control box, and finally install the control box on the driver's cab partition wall.
