[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. The terms "include", "comprises", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0037] 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 should be interpreted as having a meaning consistent with the context of this specification, and should not be interpreted in an idealized or overly rigid manner.

[0038] When using expressions such as "at least one of A, B, and C, etc.", it should generally be interpreted as the meaning of the expression generally understood by those skilled in the art. For example, "a system having at least one of A, B, and C" should include but not be limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc. When using expressions such as "at least one of A, B, or C, etc.", it should generally be interpreted as the meaning of the expression generally understood by those skilled in the art. For example, "a system having at least one of A, B, or C" should include but not be limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.

[0039] Rail vehicles need to be equipped with lighting components to meet the lighting needs in the car. At present, lighting components are generally installed on the top of the rail vehicle through a ceiling mechanism, and are mostly configured on the top plate of the ceiling mechanism. However, in actual use scenarios, due to the limited width of the top plate (i.e., the axial dimension of the rail vehicle) and the large number of functional modules configured on the top plate (such as ventilation equipment, air inlets and outlets configured by the ventilation equipment, etc.), in order to further meet the lighting needs in the car, in actual application scenarios, lighting components can also be configured on the side top plates located on both sides of the width direction of the top plate.

[0040] The structural keel is the main body of the currently used ceiling mechanism. At least some functional modules (such as prefabricated air ducts, top plates, side top plates and grilles, etc.) need to be fixed on the top of the rail vehicle through the structural keel. In order to meet the assembly requirements of each functional module, many interfaces need to be configured on the structural keel, and some functional modules also need to be equipped with additional fixings during assembly, which makes the materials used in the ceiling structure cumbersome and occupies a large space. In addition, during the assembly process, the functional modules may also affect each other, which is not conducive to disassembly and assembly.

[0041] Therefore, how to provide a ceiling mechanism and rail vehicle that requires less materials and has no interference between functional modules has become a technical problem that needs to be solved urgently.

[0042] In view of this, the embodiments of the present utility model provide a ceiling suspension mechanism and a rail vehicle based on the same concept.

[0043] Figure 1 It is an assembly diagram of a ceiling suspension mechanism according to an illustrative embodiment of the utility model.

[0044] According to the ceiling mechanism provided by the utility model, Figure 1 As shown, it includes a structural keel 1, a side top plate 4 and a lighting assembly. The structural keel 1 is suspended on the top of the rail vehicle. The side top plate 4 is pivotally mounted on the structural keel 1, and the distal end of the side top plate 4 away from the structural keel 1 is detachably mounted on an external structural member, and has an assembled state of engagement with the structural member and a separated state of disengagement from the structural member. A cavity is defined between the side top plate 4 and the inner wall of the rail vehicle. The lighting assembly is integrated on the side top plate 4, and at least a portion of the lighting assembly is enclosed in the cavity in response to the assembled state of the side top plate 4, and is exposed to the external environment in response to the separated state of the side top plate 4, so as to be operated.

[0045] In such an embodiment, the lighting assembly is integrated into the side top panel, and the side top panel 4 can be pivotally mounted directly on the structural keel 1, which not only eliminates the need for additional fixings, but also forms an openable cavity between the side top panel 4 and the inner wall of the rail vehicle, and the cavity is suitable for assembling other functional modules or additional devices so as to be isolated from the external environment in a closed state, and in an open state, the other functional modules or additional devices in the cavity are exposed to the external environment to be operated, so that the staff does not need to remove the functional modules of the ceiling mechanism for operation when performing maintenance and / or inspection.

[0046] According to the embodiments of the present utility model, Figure 1 As shown, the lighting assembly includes a lighting unit 5 and a control unit 3. The lighting unit 5 is used as a light source. The control unit 3 and the lighting unit 5 are electrically connected to turn the circuit of the lighting unit 5 on or off.

[0047] In an illustrative embodiment, Figure 1 As shown, the lighting unit 5 includes but is not limited to a substrate, a circuit disposed on the substrate, and a plurality of LED light groups arranged on the substrate. Specifically, the plurality of LED light groups form a light strip in an array along the length direction and / or the width direction.

[0048] In an illustrative embodiment, Figure 1 As shown, the control unit 3 includes but is not limited to a connector. Specifically, contacts are provided in the connector so that the lighting unit 5 is connected to the power supply circuit of the rail vehicle, thereby controlling the lighting unit 5 to be turned on or off.

[0049] In an illustrative embodiment, Figure 1 As shown, the control unit 3 includes but is not limited to the first surface of the side top plate 4 (such as Figure 1 The protruding portion (shown on the upper left surface) is fixed to the side top plate 4.

[0050] In this embodiment, the control unit 3 of the lighting assembly is installed in the cavity formed between the side top plate and the inner wall of the rail vehicle. When the side top plate 4 is in the assembled state, the control unit 3 is enclosed in the cavity. When the side top plate 4 is in the separated state from the structural member, the side top plate 4 can swing downward by its own weight (e.g., Figure 1 The left side shown in the figure swings to the right side), so that the distal end of the side top plate 4 (as shown in the figure) Figure 1 An opening is formed between the left end (shown) and the structural member, so that the control unit 3 is exposed to the external environment, so that the staff can perform operations (such as disassembly, installation, maintenance, etc.). It should be understood that the embodiments of the utility model are not limited to this.

[0051] For example, the lighting unit 5 may also be a daylight lamp with a tubular or disc structure, a light bulb with a filament, or any other light-emitting device suitable for lighting.

[0052] For another example, the control unit 3 can be fixed to other parts in the cavity (such as the inner wall of the rail vehicle), and then connected to the lighting unit 5 through wires.

[0053] According to an illustrative embodiment of the present utility model, Figure 1 As shown, the control unit 3 is provided on a first surface of the side top plate 4 facing the inner wall of the rail vehicle, and the lighting unit 5 is provided on a second surface of the side top plate 4 facing away from the first surface.

[0054] In an illustrative embodiment, Figure 1 As shown, the side top plate 4 includes but is not limited to a box-like structure configured to be provided with an opening. Figure 1 A groove is provided on the surface shown at the lower right.

[0055] In an illustrative embodiment, Figure 1 As shown, the lighting unit 5 is disposed at the bottom of the groove of the side top plate 4. In detail, the lighting unit 5 includes but is not limited to being fixed to the side top plate 4 by bonding, welding, bolting or any other means.

[0056] In such an embodiment, the lighting part 5 of the lighting assembly is a consumable part. It is arranged in the groove formed by the side top plate 4. On the one hand, it can surround its outside, which is conducive to protecting it; on the other hand, when it fails, it is also convenient to maintain and replace it. The control part 3 is less likely to fail, so it can be arranged in the cavity shielded by the side top plate 4, which is conducive to preventing the occurrence of accidental touch. It should be understood that the embodiments of the utility model are not limited to this.

[0057] For example, the control unit 3 may also be disposed in a groove formed by the side top plate 4 .

[0058] For another example, the side top plate 4 can also be configured as a straight plate, an arc plate or any other structure. On this basis, the lighting unit 5 should be configured to respond to the shape of the side top plate 4 and fit on the second surface of the side top plate 4.

[0059] According to the embodiments of the present utility model, Figure 1 As shown, the lighting assembly further includes a lampshade 6 which is arranged on the outer side of the lighting portion 5 .

[0060] In an illustrative embodiment, Figure 1 As shown, a recessed portion is provided between the facing groove walls of the groove formed by the side top plate 4, and both ends of the lampshade 6 (such as Figure 1 The lower left end and the upper right end as shown are embedded in the recessed portion so that the lampshade 6 is fixed on the side top plate 4.

[0061] In an exemplary embodiment, the lampshade 6 is made of a transparent material so that the lampshade has both a protective function and a light transmission function. In detail, the lampshade 6 can be made of a completely transparent material (such as a transparent acrylic plate) or a partially transparent frosted material (such as frosted glass) to meet the lighting requirements of the rail vehicle compartment.

[0062] In an illustrative embodiment, Figure 1 As shown, the lampshade 6 includes but is not limited to being constructed in a plate-shaped structure. In detail, the lampshade 6 can be made of a material with a certain elasticity so that it can bend when assembled in the recessed portion, so that the distance between the two ends of the lampshade 6 (such as Figure 1 The distance from the lower left to the upper right shown in FIG. 1 is smaller than the distance between the two recessed portions, and the distance between the two ends of the lampshade 6 (as shown in FIG. 1 ) .... Figure 1The distance from the lower left to the upper right shown in the figure is substantially the same as the distance between the two recessed parts, so that the recessed parts are embedded in the recessed parts. It should be understood that the embodiments of the present utility model are not limited thereto.

[0063] For example, the lampshade 6 may be configured to protrude outward from the side top plate 4 , or to be recessed inward from the side top plate 4 .

[0064] For another example, the lampshade 6 is fixed to the side top plate 4 including but not limited to by bonding, bolting or any other method.

[0065] In such an embodiment, the lampshade 6 is detachably arranged on the outside of the lighting unit 5 , which is used to isolate the lighting unit from the external environment and can be disassembled when a failure occurs in the lighting unit 5 so that the staff can repair the lighting unit 5 .

[0066] According to another illustrative embodiment of the utility model, not shown in the figure, the control unit 3 and the lighting unit 5 are both arranged on the first surface of the side top plate 4 facing the inner wall of the rail vehicle, and the side top plate 4 is provided with a light-transmitting hole that penetrates the first surface and the second surface, so that the light emitted by the lighting unit 5 can be transmitted outside the cavity.

[0067] In an illustrative embodiment, not shown in the figure, the side top plate 4 can be constructed as a plate-like structure. In detail, a light-transmitting hole is provided on the side top plate 4. Further, the substrate of the lighting unit 5 is provided on the first surface of the side top plate 4, and the LED lamp group of the lighting unit 5 is embedded in the light-transmitting hole and protrudes from the second surface of the side top plate 4, so that the light emitted by the lighting unit 5 is transmitted from the second surface of the side top plate 4. Furthermore, a coating structure formed by a light-transmitting glue can be configured on the second surface of the side top plate 4, so as to be used as a lampshade to cover the lamp beads of the LED lamp group under the light-transmitting glue, thereby isolating and protecting the lighting unit 5.

[0068] In such an embodiment, by configuring the side top plate 4 into a plate-like structure and allowing light to pass through the provided light-transmitting holes, the lighting unit 5 and the control unit 3 are enclosed in the cavity, and the thickness of the side top plate 4 is reduced, thereby saving space.

[0069] According to the embodiments of the present utility model, Figure 1 As shown, the ceiling suspension mechanism further includes a lock 7 disposed at the distal end of the side top plate 4, which is suitable for detachably mounting the side top plate 4 on the structural member.

[0070] In an illustrative embodiment, Figure 1 As shown, the distal end of the side top plate 4 (such as Figure 1 The lower left end shown in the figure) is not limited to the arc-shaped portion and the arc-shaped portion are arranged in sequence along the horizontal direction (i.e. Figure 1 In detail, the lock 7 includes but is not limited to being installed on the connecting portion.

[0071] In such an embodiment, the shape of the connecting portion can be configured to suit the shape of the matching structural member, and the arc portion is beneficial to improving the structural strength between the side top plate 4 and the structural member, making it easier to design and shape the side top plate 4.

[0072] In an illustrative embodiment, Figure 1 As shown, the lock 7 includes a housing, a lock core and a lock tongue. In detail, the housing is mounted on the connecting portion of the side top plate 4. The lock core is rotatably mounted in the housing, and a lock hole is provided on one side of the lock core located on the second surface of the side top plate 4.

[0073] In an illustrative embodiment, Figure 1 As shown, the lock tongue (i.e. Figure 1 The S-shaped member (shown in the figure) disposed on the upper part of the lock 7 is integrally mounted on the lock core and is configured to rotate integrally with the lock core. Specifically, when the lock hole (not shown in the figure) of the lock 7 is inserted with an unlocking tool (such as a key), the lock tongue responds to the rotation of the lock core of the lock and is locked in the locking position (such as the locking position) where the structural member is engaged. Figure 1 The side top plate 4 is swung between a position (shown in the figure) and an open position (not shown) separated from the structural member, so that the side top plate 4 has an assembled state and a separated state.

[0074] In such an embodiment, the proximal end of the side top plate 4 can be pivotally mounted on the structural keel 1, and the distal end of the side top plate 4 is engaged with the structural member through the lock 7, which not only limits the openable and closable cavity, but also prevents the structural member, the side top plate and the structural keel 1 from interfering with each other. When the side top plate 4 is in a separated state from the structural member, the side top plate 4 can be opened from the assembled state by its own weight, thereby exposing the cavity to the external environment. Since the proximal end of the side top plate 4 is suspended on the structural keel 1 at this time, the staff does not need to disassemble or support the side top plate to inspect and repair the device in the cavity.

[0075] Figure 2 yes Figure 1 A partial enlarged view of a structural keel portion of the exemplary embodiment shown.

[0076] According to the embodiments of the present utility model, Figure 2 As shown, a first receiving groove is provided at the lower end of the structural keel 1. A shaft-shaped portion 41 is provided at the proximal end of the side top plate 4 facing the structural keel 1, and the shaft-shaped portion 41 is adapted to be embedded in the first receiving groove so that the side top plate 4 swings relative to the first receiving groove around the axis of the shaft-shaped portion 41.

[0077] According to the embodiments of the present utility model, Figure 2 As shown, a hook-shaped portion 111 is provided at the lower end of the structural keel 1 , and a first receiving groove is provided on one side of the hook-shaped portion 111 .

[0078] According to the embodiments of the present utility model, Figure 2 As shown, the structural keel 1 is further provided with a limiting member 112 , which is arranged at intervals at the notch of the first receiving groove and is suitable for pressing against the outer side of the shaft-shaped portion 41 to limit the shaft-shaped portion 41 in the first receiving groove.

[0079] In an illustrative embodiment, Figure 2 As shown, the first receiving groove includes but is not limited to being configured as a U-shaped groove. Further, the proximal end of the side top plate 4 (such as Figure 2 The right end shown in FIG. 1 is constructed into an L-shaped structure, and the end thereof is provided with a Figure 2 The shaft-shaped portion 41 shown extends in the direction facing the paper. When the shaft-shaped portion 41 is engaged with the first receiving groove, the axis of the shaft-shaped portion 41 coincides with the extending direction of the axis of the U-shaped groove provided in the first receiving groove, so that the side top plate 4 can swing around the axis of the shaft-shaped portion 41 relative to the structural keel 1.

[0080] In an illustrative embodiment, Figure 2 As shown, the hook-shaped portion 111 is provided with a plurality of holes above the notch of the first receiving groove along the horizontal direction (such as Figure 2 The limiting member 112 extends in the left and right directions as shown. In detail, the spacing between the limiting member and the notch of the first receiving groove is substantially the same as the width of the proximal end of the side top plate 4 configured into an L-shaped structure.

[0081] In such an embodiment, the proximal end of the side top plate 4 configured as an L-shaped structure can be fitted in the spacing between the stopper and the notch of the first receiving groove in an interference fit in the assembled state, and can be pressed against the outer side of the proximal end of the side top plate 4 when the hook-shaped portion 111 is fitted in the first receiving groove, so that the side top plate 4 can be prevented from coming out of the structural keel 1 while being able to accommodate the swing of the side top plate 4 relative to the structural keel 1. In this way, the side top plate 4 and the structural keel 1 are assembled only through the convex and concave parts formed by themselves, without the participation of other fixing parts, which reduces the required materials and saves space.

[0082] According to the embodiments of the present utility model, Figure 1 and Figure 2 As shown, the ceiling suspension mechanism further comprises a grid plate 2 installed on the structural keel 1 .

[0083] In an illustrative embodiment, Figure 2 As shown, the other side of the hook-shaped portion 111 provided on the structural keel 1 is also provided with a second receiving groove similar to the first receiving groove. In detail, one of the second receiving groove and the grid plate 2 forms a concave portion, and the other forms a convex portion suitable for fitting with the concave portion. Further, the hook-shaped portion 111 is provided with a horizontal direction (such as Figure 2The limiting member 112 extends in the left and right directions as shown. In detail, the spacing between the limiting member and the notch of the second receiving groove is substantially the same as the width of the joint portion of the grid plate 2.

[0084] In such an embodiment, based on the similar way of the side top plate 4 and the hook-shaped portion 111, the end of the grid plate 2 can be embedded in the spacing between the stopper and the notch of the second receiving groove, so that the grid plate 2 is restricted in the second receiving groove. In this way, the grid plate 2 and the structural keel 1 are assembled only through the convex and concave parts formed by themselves, without the participation of other fixing parts, further reducing the required materials.

[0085] According to the rail vehicle provided by the utility model, Figure 1 As shown, a ceiling mechanism is provided, wherein a structural keel 1 of the ceiling mechanism is installed on the top surface of the inner wall of the rail vehicle, a fixing plate 8 is provided on the side of the inner wall of the rail vehicle, and the distal end of the side top plate 4 of the ceiling mechanism is detachably installed on the fixing plate 8.

[0086] According to the embodiments of the present utility model, Figure 1 As shown, a ventilation device is arranged on the top surface of the inner wall of the rail vehicle, and the grid plate 2 in the ceiling mechanism is covered on the outside of the air inlet and / or the air outlet of the ventilation device.

[0087] In an illustrative embodiment, Figure 1 As shown, the rail vehicle is equipped with a ventilation device. Specifically, the air inlet and / or the air outlet of the ventilation device are arranged on the top of the rail vehicle.

[0088] In an illustrative embodiment, Figure 1 As shown, the structural keel 1 includes a first structural beam 11 and a second structural beam 12. In detail, the first structural beam 11 and the second structural beam 12 are arranged in parallel on both sides of the air inlet and / or the exhaust port. Further, the first structural beam 11 and the second structural beam 12 are installed with a grid plate 2 to serve as a grille of a ventilation device. The ventilation device includes but is not limited to any one of air conditioning, fresh air or other ventilation devices suitable for guiding the flow of gas in the compartment of the rail vehicle.

[0089] In an illustrative embodiment, Figure 1 As shown, one end of the grid plate 2 (such as Figure 1 The left end of the grid plate 2 (as shown in FIG. 1 ) is engaged in the second receiving groove formed by the hook-shaped portion 111, and the other end of the grid plate 2 (as shown in FIG. 1 ) is engaged in the second receiving groove formed by the hook-shaped portion 111. Figure 1 The right end shown in the figure is embedded in the bottom surface of the second structural beam 2 through a truss structure. In this way, the grid plate 2 can be assembled on the structural keel 1 without other fixing parts. It should be understood that the embodiments of the utility model are not limited to this.

[0090] For example, in order to improve the sealing between the structural keel 1 and the grid plate 2, a sealing device, such as a sealing strip, may be configured at the joint position between the first structural beam 11 and the grid plate 2 and / or the joint position between the second structural beam 12 and the grid plate 2, so as to prevent the airflow passing through the ventilation equipment from leaking out along the joint position between the grid plate 2 and the structural keel 1.

[0091] In an illustrative embodiment, Figure 1 As shown, a fixing plate 8 extending in the horizontal direction is also provided on the inner wall of the rail vehicle, serving as a structural member, and the proximal end of the side top plate 4 (such as Figure 1 The left end shown in FIG. 1 is detachably mounted on the fixing plate 8 through a lock 7. It should be understood that the embodiments of the present utility model are not limited thereto.

[0092] For example, the extending direction of the fixing plate 8 is inclined from one side to the other side (such as from the left side to the right side).

[0093] For another example, the fixing plate 8 may be arranged upward in the vertical direction.

[0094] In such an embodiment, Figure 1 In the left and right directions shown, the fixing plate 8, the side top plate 4, the first structural beam 11, the grid plate 2 and the second structural beam 12 are arranged in sequence. In this way, the functional modules do not block each other, and in the process of assembling or disassembling a functional module, the functional modules do not interfere with each other. Furthermore, the side top plate 4 and the grid plate 2 are directly assembled with the structural keel 1 and the structural parts through the concave and convex parts formed by themselves, so there is no need to configure additional fixing parts.
