Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and in particular to a windshield snow protection device and a rail vehicle. Background Technology

[0002] Existing railway vehicles have windshields installed at the end of the vehicles. The main structure of the windshield is made of flexible tarpaulin. The function of the windshield is to form a connecting passage between vehicles, prevent wind, sand, rain and snow from entering the vehicle, and ensure that passengers can move freely inside the train.

[0003] In related technologies, the windshield itself is a flexible structure that needs to accommodate relative movement between the two carriages, including stretching, compression, torsion, and misalignment. However, the windshield has structural defects when dealing with heavy snow and extremely cold environments. Specifically, when the train is running in heavy snow, snow accumulates in large quantities at the folds of the canopy at the top of the windshield and freezes. Once frozen, the canopy loses its flexibility and can no longer stretch or compress. When the two carriages move relative to each other, the canopy will tear, causing damage to the windshield and allowing snowmelt to leak into the carriages, affecting the safety and comfort of the train operation.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0080] like Figures 1 to 14 As shown, this application embodiment provides a windshield snow protection device 60, including: a first cover plate assembly 610 and a second cover plate assembly 620. The first side cover plate 612 assembly includes a first mounting base 611, a first side cover plate 612, and a sliding support base 613. The first mounting base 611 is used to install on the end of a carriage 601, the first side cover plate 612 is connected to the first mounting base 611, and the sliding support base 613 is disposed on the first side cover plate 612. The second cover plate assembly 620 includes a second mounting base 621 and a second side cover plate. The second mounting base 621 is used to install on the end of another carriage 601, the second side cover plate is connected to the second mounting base 621, and the second side cover plate is supported by the sliding support base 613. When the two carriages 601 are in relative motion, the second side cover plate can slide along the sliding support base 613.

[0081] The first cover plate assembly 610 and the second cover plate assembly 620 are respectively connected to two adjacent carriages 601. The first cover plate assembly 610 and the second cover plate assembly 620 are not rigidly connected; they are independent components, with one overlapping the other. When the two carriages 601 are in relative motion, the first cover plate assembly 610 and the second cover plate assembly 620 can slide relative to each other.

[0082] The windshield snowproof device 60 of this application can be installed above the windshield 602 between two adjacent carriages 601, forming a flexible, shielding snowproof cover that allows for movement between the vehicles. This windshield snowproof device 60 prevents snow from falling on the windshield 602, effectively solving problems such as tearing and damage to the windshield 602 caused by freezing snow in heavy snow conditions, thus ensuring the safety and comfort of train operation.

[0083] In some possible implementations, such as Figure 7As shown, the sliding support 613 has multiple balls 6133 protruding from the first side cover plate 612, and the second cover plate assembly 620 is supported on each ball 6133. Each ball 6133 can rotate freely. When two adjacent carriages 601 move relative to each other, the second cover plate assembly 620 can slide along the balls 6133, improving the sliding friction between the first cover plate assembly 610 and the second cover plate assembly 620 into a rolling fit, reducing frictional resistance, reducing wear, extending the service life of the windshield snow protection device 60, and also reducing noise.

[0084] In this embodiment, the cover plate assembly of the windshield snow protection device 60 can be made of metal plate, which can form a flexible structure to meet the relative movement between the two vehicles, including movements such as stretching, compression, torsion, misalignment and lifting.

[0085] In some possible implementations, such as Figures 6 to 9 As shown, the first side cover 612 includes a cover body 6121 and a boss cover portion 6122. One side of the cover body 6121 is connected to the first mounting base 611, and the boss cover portion 6122 is disposed on the other side of the cover body 6121, protruding from the cover body 6121. A sliding support seat 613 is disposed on the boss cover portion 6122, and a ball bearing 6133 extends out of the boss cover portion 6122. The second side cover can overlap the sliding support seat 613 on the boss cover portion 6122.

[0086] The boss cover 6122 can extend a certain length along the side edge of the cover body 6121 away from the first mounting base 611. The first cover assembly 610 can include multiple sliding support seats 613. Each sliding support seat 613 can be disposed on the boss cover 6122, and each sliding support seat 613 is arranged sequentially at intervals along the length direction of the boss cover 6122.

[0087] In some possible implementations, such as Figure 7 As shown, the sliding support 613 includes a base plate 6131 and a ball bearing retainer plate 6132. The base plate 6131 is connected to the cover plate body 6121. A cavity is formed between the base plate 6131 and the concave side of the boss cover 6122. An avoidance opening communicating with the cavity is provided on the boss cover 6122. The ball bearing retainer plate 6132 is located in the cavity and fixed to the base plate 6131. ​​Each ball bearing 6133 is rotatably disposed on the ball bearing retainer plate 6132 and extends out of the avoidance opening.

[0088] The fastener can pass through the base plate 6131 and bead plate 6132 at one end. The top of the bead plate 6132 can have a boss, and a ball is set on the boss. The boss can be embedded in the clearance opening, realizing the precise assembly of the bead plate 6132 and the boss cover 6122.

[0089] In some possible implementations, a hemispherical groove may be formed on the ball bearing plate 6132, and a ball bearing 6133 may be accommodated in the hemispherical groove, with the spherical portion extending out of the hemispherical groove. The ball bearing plate 6132 may include two plates that are interlocked, forming an inner groove between them. An opening is formed on the upper plate, and the ball bearing 6133 is partially located in the inner groove and partially extends out of the opening.

[0090] In some possible implementations, such as Figures 7 to 9 As shown, the windshield snow protection device 60 includes a first fixing component 614, a first mounting base 611 having a first slot, and a first insertion seat 6123 provided at one end of the first side cover 612 away from the sliding support base 613. The first insertion seat 6123 is inserted into the first slot, and the first fixing component 614 fixes the first insertion seat 6123 to the first mounting base 611. During the assembly of the first cover component 610, the first insertion seat 6123 is first inserted into the first slot of the first mounting base 611, and then the first fixing component 614 fixes the first insertion seat 6123 to the first mounting base 611.

[0091] In some possible implementations, the first mounting base 611 includes a first vertical base plate 6111 and a first lateral limiting plate 6112. A first slot is formed on the first vertical base plate 6111. The first lateral limiting plate 6112 is connected to the first vertical base plate 6111 and has a first longitudinal gap with the first vertical base plate 6111. The first insertion base 6123 includes a first base body 61231 and a first insertion plate 61232 vertically connected to the first base body 61231. The first insertion plate 61232 is inserted into the first slot. The first base body 61231 passes through the longitudinal gap. The first vertical base plate 6111 and the first lateral limiting plate 6112 are limited to both sides of the first base body 61231 along the thickness direction, which serves as a limiting function.

[0092] When both the first mounting base 611 and the first side cover are arc-shaped, the first insert plate 61232 along the edge of the first side cover 612 can be gradually inserted into the first slot along one end of the first slot.

[0093] In some possible implementations, the first fixing component 614 includes a first clamping block 6141 and a first screw 6142. A first groove is provided on the first insertion seat 6123, and one end of the first clamping block 6141 is embedded in the first groove. The first screw 6142 is threadedly connected to the first clamping block 6141 and abuts against the first mounting base 611. The first clamping block 6141 can be effectively fixed to the first mounting base 611 by tightening the first screw 6142, such as abutting against the first vertical base plate 6111 of the first mounting base 611.

[0094] In some possible implementations, such as Figure 7As shown, the second side cover assembly includes a second inner side cover 622 and a second outer side cover 623. The second inner side cover 622 is detachably connected to the second mounting base 621, and the second outer side cover 623 is rotatably connected to the second inner side cover 622. The second outer side cover 623 is supported on a sliding support base 613. The second outer side cover can swing up and down relative to the second inner side cover. When two adjacent carriages 601 move up and down relative to each other, the second outer side cover 623 can swing up or down to accommodate the vertical misalignment of the two adjacent carriages 601.

[0095] In some possible implementations, a pivot is provided on the side of the second inner cover 622 opposite to the second mounting base 621, and the second outer cover 623 is rotatably connected to the pivot. The pivot and the second inner cover 622 are connected by reinforcing ribs.

[0096] The second outer cover 623 is a flexible flip-up plate, which can be made of aluminum plate. The second inner cover 622 is made of aluminum profile and bent. The pivot can be made of stainless steel. The first cover 612 can be made of aluminum profile and bent.

[0097] The balls can be made of stainless steel, the ball holder plate 6132 can be made of nylon, and the base plate 6131 can be made of stainless steel.

[0098] In some possible implementations, such as Figures 13 to 16 As shown, the second side cover plate includes an elastic connecting assembly 625, which includes a shaft 6251, a sleeve 6252, and a torsion spring 6253. One of the shaft 6251 and the sleeve 6252 is connected to the second side outer cover plate 623, and the other is connected to the second side inner cover plate 622. The sleeve 6252 is sleeved on the shaft 6251. The torsion spring 6253 is located inside the sleeve 6252 and sleeved on the shaft 6251. The two ends of the torsion spring 6253 are respectively limited to the sleeve 6252 and the shaft 6251. Under the action of the elastic force of the torsion spring 6253, the second side outer cover plate 623 is elastically supported on the sliding support seat 613.

[0099] Specifically, the elastic connection assembly 625 can have two torsion springs 6253 and two shafts 6251. A fixing block 62521 can be provided in the middle of the sleeve 6252. The sleeve 6252 can be fixed to the edge of the second inner cover plate, while the two shafts 6251 can be set on the second outer cover plate 623. The two shafts 6251 extend out of the sleeve 6252 from both ends. The two torsion springs 6253 are respectively sleeved on the two shafts 6251. The ends of the two torsion springs 6253 that are close to each other are limited to the fixing block 62521, and the ends of the two torsion springs 6253 that are opposite to each other are limited to the corresponding shafts 6251.

[0100] The elastic connection component 625 of this application has a damping and vibration-damping function. Before installing the elastic connection component 625, the torque of the torsion spring 6253 can be pre-adjusted to ensure that the upper cover plate is always pressed against the sliding support seat with a certain pressure, so as to avoid the second side cover plate jumping and generating metal collision noise due to wind or vehicle vibration.

[0101] In some possible implementations, such as Figure 8 As shown, the second outer cover plate 623 has a downward bent edge 6231 on the side opposite to the second inner cover plate 622. The downward bent edge 6231 is close to the upper surface of the first cover plate 612.

[0102] In some possible implementations, such as Figure 7 As shown, the windshield snow protection device 60 includes a second fixing component 624, a second mounting base 621 having a second slot, a second plug-in seat 6221 provided on the side of the second inner cover plate 622 opposite to the second outer cover plate 623, the second plug-in seat 6221 being inserted into the second slot, and the second fixing component 624 fixing the second plug-in seat 6221 to the second mounting base 621.

[0103] The assembly structure of the second side inner cover plate 622 and the second insertion seat 6221 is similar to the connection structure between the first side cover plate 612 and the first mounting seat 611. For example, the second mounting seat 621 includes a second vertical seat plate and a second lateral limiting plate. A second slot is formed on the second vertical seat plate. The second lateral limiting plate is connected to the second vertical seat plate and has a second longitudinal gap with the second vertical seat plate. The second insertion seat 6221 includes a second seat body and a second insertion plate vertically connected to the second seat body. The second insertion plate is inserted into the second slot. The second seat body passes through the longitudinal gap. The second vertical seat plate and the second lateral limiting plate are located on both sides of the second seat body along the thickness direction.

[0104] In some possible implementations, the second fixing component 624 includes a second clamping block and a second screw, and the second fixing component 624 has the same structure as the first fixing component. A second groove is provided on the second insertion seat 6221, one end of the second clamping block is embedded in the second groove, and the second screw is threadedly connected to the second clamping block and abuts against the second mounting seat 621.

[0105] In some possible implementations, both the first cover assembly 610 and the second cover assembly 620 are arched or arc-shaped with a central upward convexity, which can effectively prevent snow from falling onto the top of the windshield 602 tarpaulin.

[0106] The windshield snow protection device 60 of this application is an overall convex arc-shaped cover. On the one hand, it can cover the upper part of the tarpaulin windshield 602 to prevent foreign objects from entering the upper part of the tarpaulin windshield 602. On the other hand, it can prevent water, sand and snow accumulation. When there is rain, sand, snow or other debris on the arc-shaped top of the windshield snow protection device 60, the debris can slide smoothly down the arc-shaped slope of the windshield snow protection device 60 with the vibration of the vehicle. After the windshield snow protection device 60 of this application is installed, snow will not accumulate and freeze on the top of the tarpaulin windshield 602, thereby avoiding problems such as tearing and damage to the tarpaulin 602 tarpaulin due to the freezing of snow water in the folds of the tarpaulin when the tarpaulin windshield 602 is stretched, compressed or misaligned during driving.

[0107] This application also provides a rail vehicle, including: multiple carriages 601 and the aforementioned windshield snowproof device 60. The carriages 601 are arranged sequentially, with adjacent carriages 601 connected together. The windshield snowproof device 60 is located between adjacent carriages 601, and its first mounting base 611 and second mounting base 621 are respectively connected to the adjacent carriages 601. The first mounting base 611 and second mounting base 621 can be connected to the carriages 601 by fasteners. A windshield 602 is provided between adjacent carriages 601, and the windshield snowproof device 60 can be located on top of the windshield 602, covering it. This prevents snow from accumulating and freezing on the tarpaulin of the windshield 602, thus avoiding problems such as tearing and damage to the tarpaulin 602 tarpaulin due to snow water freezing into the folds when the tarpaulin 602 is stretched, compressed, or misaligned during operation.
