[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0032] The core of this invention is to provide a lightweight rail vehicle skirt device. Another core aspect of this invention is to provide a rail vehicle including the aforementioned rail vehicle skirt device, which has a relatively light overall weight.
[0033] Please refer to Figure 1 This utility model provides a rail vehicle skirt device, including an arc-shaped skirt 1 and an arc-shaped rib 2. The arc-shaped skirt 1 is a composite material skirt and is formed by pultrusion. The arc-shaped rib 2 is a composite material and is formed by autoclave molding. The arc-shaped rib 2 is connected to the arc-shaped skirt 1.
[0034] In other words, both the arc-shaped skirt 1 and the arc-shaped rib 2 in this embodiment of the invention are made of composite materials, replacing the aluminum alloy materials in related technologies, in order to reduce the overall weight of the rail vehicle skirt device and achieve lightweighting of the rail vehicle skirt device. Moreover, this embodiment of the invention uses pultrusion molding to form the arc-shaped skirt 1, which is beneficial to improve production efficiency, reduce costs, and ensure the overall consistency of the arc-shaped skirt 1, ensuring the stability of the quality of the arc-shaped skirt 1. The arc-shaped rib 2 is formed by autoclaving, which can improve the strength, rigidity and fatigue life of the arc-shaped rib 2. By combining different molding processes, the overall reliability of the rail vehicle skirt device is ensured while improving production efficiency.
[0035] It should be noted that the curved skirt panel 1 is formed by pultrusion, and can be integrally pultruded. The curved rib 2 is formed by autoclave molding, and can be manually laid by autoclave molding.
[0036] Furthermore, this embodiment does not limit the specific connection method between the curved rib 2 and the curved skirt plate 1, as long as the connection between the curved rib 2 and the curved skirt plate 1 can be achieved. For example, the curved rib 2 and the curved skirt plate 1 can be bonded together with structural adhesive.
[0037] To further enhance the structural strength and stiffness of the curved skirt 1, such as Figure 2 As shown, in some embodiments, the curved skirt 1 has flange edges 11 at both ends along the first direction.
[0038] In other words, this embodiment enhances the structural strength and rigidity of the curved skirt plate 1 by providing flange edges 11, thereby strengthening the curved skirt plate 1. It should be noted that this embodiment does not limit the first direction. For example, the first direction can be the vertical direction of the curved skirt plate 1, that is, flange edges 11 are respectively provided at the upper and lower ends of the curved skirt plate 1. It can be understood that the extension direction of the flange edges 11 has an angle with the first direction. For example, the extension direction of the flange edges 11 is perpendicular to the first direction. That is, when the flange edges 11 are provided at both ends of the vertical direction of the curved skirt plate 1, the flange edges 11 extend along the horizontal direction of the curved skirt plate 1.
[0039] Furthermore, such as Figure 2 As shown, in some embodiments, the flange edge 11 has an angle with the arc-shaped skirt 1, and the flange edge 11 faces the inside of the arc-shaped skirt 1.
[0040] In other words, the flange edge 11 forms a bent structure relative to the arc-shaped skirt 1, which can be formed by bending the two ends of the arc-shaped skirt 1 along the first direction. In this embodiment, by making the flange edge 11 and the arc-shaped skirt 1 have an angle, the edge of the arc-shaped skirt 1 is strengthened, the bending and torsional stiffness of the arc-shaped skirt 1 is improved, the additional reinforcing ribs 3 are avoided, and the process is simplified.
[0041] Furthermore, such as Figure 1 As shown, in some embodiments, the curved skirt 1 is provided with at least one reinforcing rib 3 along the second direction, and the reinforcing rib 3 has an angle with the curved bending rib 2.
[0042] In other words, this embodiment enhances the strength and stiffness of the curved skirt plate 1 along the second direction by providing reinforcing ribs 3 along the second direction. The reinforcing ribs 3 and the curved bending ribs 2 form an angle, meaning the reinforcing directions of the reinforcing ribs 3 and 2 are different, thus reinforcing the curved skirt plate 1 from multiple directions. For example, the curved bending ribs 2 can be provided along the first direction, and the reinforcing ribs 3 along the second direction, with the first and second directions perpendicular. Alternatively, the second direction can be the extension direction of the flange edge 11; that is, this embodiment utilizes the combined effect of the flange edge 11 and the reinforcing ribs 3 to improve the stiffness of the curved skirt plate 1 along the second direction.
[0043] It should be noted that this embodiment does not limit the specific number of reinforcing ribs 3. The number of reinforcing ribs 3 can be one or at least two. When the number of reinforcing ribs 3 is at least two, the reinforcing ribs 3 are arranged at intervals, and the lengths of different reinforcing ribs 3 can be the same or different. In addition, there is no limitation on the cross-sectional shape of different reinforcing ribs 3.
[0044] Furthermore, the above embodiments do not limit the specific number of curved ribs 2. The number of curved ribs 2 can be one or at least two. When the number of curved ribs 2 is at least two, the curved ribs 2 are spaced apart, and the lengths of different curved ribs 2 can be the same or different. In addition, the cross-sectional shape of different curved ribs 2 is not limited.
[0045] In addition, to facilitate the movement of the curved skirt 1, such as Figure 1 As shown, in some embodiments, the curved skirt 1 is provided with a hinge 4, which is used to connect with the body of the rail vehicle.
[0046] In other words, the arc-shaped skirt 1 in this embodiment is a movable skirt 1, which can rotate relative to the vehicle body so that the arc-shaped skirt 1 can be opened when needed for convenient maintenance, etc.
[0047] Furthermore, such as Figure 1 As shown, in some embodiments, the curved skirt 1 is provided with a lock seat, and the lock seat is equipped with a rotary lock 5; the rail vehicle skirt device also includes a locking beam 6, which is used to connect with the body of the rail vehicle, and a drive strut 7 is connected between the locking beam 6 and the curved skirt 1. The drive strut 7 is used to drive the curved skirt 1 to rotate, and the rotary lock 5 and the locking beam 6 can cooperate to lock or open.
[0048] In other words, this embodiment utilizes the pushing and pulling force of the drive strut 7 to drive the curved skirt 1 to rotate, thereby opening or closing the curved skirt 1 relative to the rail vehicle body. For example, when the drive strut 7 extends, it pushes the curved skirt 1 to open (e.g., Figure 4 As shown); when the drive strut 7 retracts, it drives the arc-shaped skirt 1 to reset and close (as shown). Figure 2 (As shown). It should be noted that this embodiment does not limit the opening angle α of the curved skirt panel 1. For example, the opening angle α of the curved skirt panel 1 can be greater than 90°, such as α being 100°. It can be understood that the extension stroke of the drive strut 7 can be used as a limit for the curved skirt panel 1 in the open state. When the curved skirt panel 1 is reset and closed, the curved skirt panel 1 can be limited by abutting against the locking beam 6, or the retraction stroke of the drive strut 7 can be used to limit the curved skirt panel 1 in the closed state. It should be noted that the drive strut 7 can be a pneumatic strut, a hydraulic strut, or an electric strut, as long as the drive strut 7 can extend and retract to drive the curved skirt panel 1 to rotate open or close.
[0049] In addition, this embodiment utilizes the cooperation between the rotary latch 5 and the locking beam 6 to achieve the locking and limiting of the arc-shaped skirt panel 1 relative to the locking beam 6. That is, when the drive strut 7 drives the arc-shaped skirt panel 1 to reset and close, the locking tongue 51 of the rotary latch 5 is rotated (e.g., the locking tongue 51 of the rotary latch 5 is rotated). Figure 3 As shown, the locking tongue 51 engages with the locking beam 6, thereby locking and limiting the arc-shaped skirt 1 and the locking beam 6. When it is necessary to open the arc-shaped skirt 1, the locking tongue 51 is rotated in the opposite direction to disengage from the locking beam 6, thereby unlocking the skirt and allowing the drive strut 7 to push the arc-shaped skirt 1 open.
[0050] It should be noted that the rotary latch 5 is installed on the curved skirt plate 1 through the lock seat. The lock seat can be an aluminum alloy lock seat. The lock seat can be bonded and fixed to the curved skirt plate 1 with structural adhesive to avoid the rotary latch 5's lock head easily crushing the curved skirt plate 1 when it is directly installed on the curved skirt plate 1.
[0051] In addition, such as Figure 3 As shown, in some embodiments, at least one of the locking beam 6 and the curved skirt 1 is provided with a buffer 8, and when the rotary lock 5 is locked with the locking beam 6, the buffer 8 is located between the locking beam 6 and the curved skirt 1.
[0052] In other words, this embodiment uses a buffer 8 to cushion the impact force when the curved skirt 1 closes, preventing damage to the curved skirt 1 or the locking beam 6 caused by the tension of the drive strut 7 during closure. The buffer 8 can be installed on the locking beam 6 or on the curved skirt 1. When installed on the locking beam, the buffer 8 faces the curved skirt 1; when installed on the curved skirt 1, the buffer 8 faces the locking beam. As long as the buffer 8 is located between the locking beam 6 and the curved skirt 1, it can provide a cushioning effect.
[0053] It should be noted that this embodiment does not limit the specific shape, material and setting method of the buffer 8. For example, the buffer 8 can be a buffer rubber strip, and the buffer 8 can be fixed to the locking beam or the arc skirt plate 1 by bolts or other fasteners.
[0054] In addition, to ensure the reliable engagement of the rotary latch 5 with the lock beam, such as Figure 3 As shown, in some embodiments, at least one of the latch beam 6 and the latch 51 of the rotary latch 5 is provided with a removable gasket 9 to adjust the locking force between the latch 51 and the latch beam 6.
[0055] In other words, this embodiment uses a shim 9 to adjust the locking force between the latch 51 and the locking beam, thereby ensuring the tightness of the latch 51 and the locking beam 6, ensuring the reliable locking between the rotary latch 5 and the locking beam, and ensuring the stability and reliability of the closed state of the arc-shaped skirt 1.
[0056] It should be noted that this embodiment does not limit the thickness, quantity, or fixing method of the gasket 9. The number of gaskets 9 can be one or at least two. The gaskets 9 can be fixed by fasteners such as bolts to facilitate disassembly of the gaskets 9 and to facilitate adjustments during the process of adding gaskets 9. In addition, the gaskets 9 can be provided on the lock beam or on the curved skirt plate 1.
[0057] In addition, such as Figure 1 and Figure 2 As shown, in some embodiments, the arc-shaped skirt 1 is provided with a groove 10, and a slidable fixing member 101 is provided in the groove 10. The fixing member 101 is connected to a support rod hanger 71. The support rod hanger 71 is connected to one end of the drive support rod 7, and the other end of the drive support rod 7 is connected to the locking beam 6.
[0058] In other words, by setting the slide groove 10, the position of the fixing member 101 in the slide groove 10 is adjustable, thereby making the position of the support rod hanger 71 at one end of the fixed drive support rod 7 adjustable, so as to adjust the position of the drive support rod 7 and facilitate the adjustment and installation of the drive support rod 7.
[0059] It should be noted that the fastener 101 can be a screw or the like, to facilitate the connection between the fastener 101 and the strut hanger 71.
[0060] In addition to the aforementioned rail vehicle skirt device, this utility model also provides a rail vehicle including the rail vehicle skirt device disclosed in the above embodiments. For the structure of other parts of the rail vehicle, please refer to the relevant technology, which will not be repeated here.
[0061] The key point of this embodiment is that the rail vehicle adopts the rail vehicle skirt device disclosed in any of the above embodiments, and at least includes the beneficial effects of the rail vehicle skirt device, which will not be repeated here.
[0062] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
