Description

Through channel connecting assembly and through channel assembly comprising same

Technical Field

The utility model relates to the technical field of through channels of vehicles, in particular to a connecting assembly for connecting a through channel to an end wall of a vehicle body and the through channel assembly comprising the connecting assembly.

Background

Some vehicles (e.g., rail trains) have two or more cars. The bodies of two adjacent carriages are connected through a through passage, so that safe and comfortable passing space is provided for passengers, and the vehicles can adapt to pass through a curve track with a certain curvature. The through-channels typically include a screw frame connecting the through-channel to the end wall of the vehicle body, an intermediate frame (also known as a hinged frame) connecting the through-channel to another adjacent through-channel, a bellows assembly connected between the screw frame and the intermediate frame, and a side wall assembly for covering each of the frame structures and fasteners of the through-channel.

During the driving of the vehicle, in particular when passing through a curved road section, the bellows of the through-channel deforms and moves like pitch, nodding, torsion and the like along with the vehicle, so that the screw frame is subjected to large and complex forces, and the connection strength of the screw frame on the vehicle body end wall must be ensured.

Further, the side wall assembly is mostly of an integrated side wall and a three-piece type side wall. The clamping profile of the integrated side wall is fixed to the guide beam. The upper and lower ends of the guide beam are respectively rotatably connected to guide beam mounting seats, and the guide beam mounting seats are usually fixed on the end wall of the vehicle body.

When the Chinese middle vehicle is designed to be a through road system, the interfaces of the three-piece type side wall are uniformly adopted for the two side walls of the integral side wall and the three-piece type side wall. The positions of the interfaces (such as the interface holes) reserved for the guide beam installation seats on the vehicle body end wall are uniformly the interface positions of the three-piece type side walls. For the integrated side wall, the vertical distance of the interface position of the integrated side wall is too large, so that the integrated side wall is not suitable for mounting the guide beam mounting seat of the integrated side wall. In other words, the guide beam mount of the integral side wall cannot be directly mounted at the interface position reserved by the generic design. The existing solution is that a guide beam mounting seat of an integrated side wall is directly welded on a screw frame, and a folding shed component is also connected to the screw frame, so that the folding shed component and the guide beam assembly are fixed on a vehicle body end wall through the screw frame. However, the screw frame installed in this way is required to bear the tensile force of the folding shed and the tensile force of the guide beam of the side wall, and the working tensile force of the guide beam is large and has a certain force arm. The screw frame therefore requires a large cross section (in particular a welding surface for welding the guide beam mount that is as large as possible) to meet the force requirements. The screw frame with large section can not be bent and can only be manufactured by adopting a multi-section splice welding mode (eight-section splice welding is commonly used in the prior art). The welding process is complex and takes a long time. And the whole screw frame has heavy weight and wastes materials.

In addition, the guide beam guide seat is directly welded on the screw frame, the folding shed needs to be replaced after being used for a certain time (for example, after 10 years to 15 years), the screw frame is scrapped during replacement, the guide beam installation seat welded on the screw frame needs to be scrapped synchronously, and the replacement cost is high.

Detailed Description

Embodiments of the present utility model are described below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding and enabling description of the utility model to one skilled in the art. It will be apparent, however, to one skilled in the art that the present utility model may be practiced without some of these specific details. Furthermore, it should be understood that the utility model is not limited to specific described embodiments. Rather, any combination of the features and elements described below is contemplated to implement the utility model, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly set out in a claim.

Terms such as "first," "second," and the like are used hereinafter to describe elements of the present application, and are merely used for distinguishing between the elements and not for limiting the nature, order, or number of such elements. The terms "comprising" and "having" are intended to be inclusive and mean that there may be additional elements/components other than the listed elements/components.

According to one exemplary embodiment, as shown in fig. 1 to 7, the present utility model provides a through-channel connection assembly for connecting a through-channel to a body end wall of a vehicle. It should be noted that although the present utility model has been described with respect to a through-channel connection assembly for a rail train, it will be appreciated by those skilled in the art that the present utility model may be adapted for use in other vehicles such as rail-less trains or buses where a through-channel connection between two adjacent vehicles is desired.

In the description of the present utility model, the use of the "fore-aft direction" is with respect to the direction of travel of the rail train. The "left-right direction" is used to denote a horizontal extension direction perpendicular to the direction of travel of the rail train. In this context, the terms "upper", "lower", "above", "below" and the like are relative to the ground on which the rail train is traveling, with the orientation closer to the ground being "lower" and vice versa. Herein, "inner" and "outer" are with respect to the inside and outside of the vehicle body space.

As an exemplary embodiment, the present utility model provides a through-channel connection assembly including a screw frame 1, two pairs (four) of oppositely disposed connection members 2, and two pairs (four) of guide beam mounts 3 respectively connected to each connection member 2, as shown in fig. 1 to 3. The screw frame 1 is generally rectangular or square, and includes two side frames 11 disposed in a vertical direction (i.e., up-down direction), respectively, and top and bottom frames 13 and 12 disposed in a horizontal direction (i.e., left-right direction), respectively. Each connecting member 2 is connected with a guide beam mounting seat 3 for mounting a side wall guide beam (not shown in the figure) of the through passage, and the guide beam mounting seat 3 protrudes out of the plane of the screw frame 1 for rotatably mounting the upper end or the lower end of the guide beam. Each connecting member 2 is configured to be mounted to a vehicle body end wall together with the side frames 11 by means of an interface hole provided in the vehicle body end wall for mounting the side frames 11.

In this exemplary embodiment, the guide beam mount 3 can be mounted to the body end wall through the connector 2 in the interface hole for mounting the side frame 11, that is, the guide beam mount 3 is mounted while the screw frame 1 is mounted using the interface hole for mounting the side frame 11 on the body end wall, so that the guide beam mount 3 of the integrated side wall can be mounted to the body end wall of the unified design without welding the guide beam mount of the integrated side wall to the screw frame as in the prior art. The problem that the screw frame directly bears the tensile force from the guide beam mounting seat due to the fact that the guide beam mounting seat is connected to the screw frame is avoided. And therefore, the screw frame does not need a larger section any more, so that the screw frame can be manufactured by using a bendable section, a multi-section splice welding mode is not needed, and the screw frame can be manufactured by welding two end parts of an extruded section with a smaller section after the extruded section is bent and molded, thereby saving welding time and materials and improving manufacturing manufacturability. The extrusion profile can be made by an aluminum extrusion molding process. And the cross section size of the screw frame is smaller, the material is less, and the weight is smaller.

According to an exemplary embodiment of the utility model, the position of each connecting piece 2 in the through-channel connection assembly is arranged such that, on the one hand, the height of the guide beam mounting seat 3 connected thereto is adapted to the height of the upper or lower end mounting location of the side wall guide beam and, on the other hand, the connecting piece 2 is adapted to be connected to an interface hole provided in the body end wall for mounting the side frame 11.

In this example, the setting position of the guide beam mount 3 on the connecting member 2 can be flexibly selected as required, so that the mounting position of the guide beam mount can be better adapted to the positions of the mounting portions of the upper and lower ends of the guide beam.

As shown in fig. 1 to 3, the number of the connection pieces 2 on each side frame 11 is two, and the two connection pieces 2 are arranged at an interval up and down along the extending direction of the side frame 11. The upper connecting piece 2 can be arranged in particular at the connection between the proximal side frame 11 and the top side frame 13, and the lower connecting piece 2 can be arranged in particular at the connection between the proximal side frame 11 and the bottom side frame 12. Each connecting piece 2 is connected with a guide beam mounting seat 3, two guide beam mounting seats 3 are arranged corresponding to the left side of the through channel, and two guide beam mounting seats 3 are arranged corresponding to the right side of the through channel. The left two guide beam mounting seats 3 are used for mounting the upper end and the lower end of the left side wall guide beam, and the right two guide beam mounting seats 3 are used for mounting the upper end and the lower end of the right side wall guide beam.

As a specific example of the connector 2, the connector 2 on each side frame 11 includes a connector body 21, and the cross-sectional view of the connector body 21 and the guide beam mount 3 shown in fig. 4 and 5 is taken as an example, one end (outer end) of the connector body 21 being connected to the side frame 11 of the screw frame 1, and the outer end of the guide beam mount 3 being connected to the other end (inner end) of the connector body 21.

As a specific example of the connector body 21, as shown in fig. 4 to 6, the connector body 21 includes a hollow member 211 and a first extension plate 212 connected to one side of the hollow member 211, and the connector body 21 may be integrally formed. Taking the connector main body 21 shown in fig. 6 as an example, the hollow member 211 is adapted to be attached to the vehicle body end wall together with the screw frame 1 via an interface hole for mounting the side frame 11 reserved on the vehicle body end wall at the outer side of the side frame 11, and the first extension plate 212 is provided extending inwardly from the inner side of the hollow member 211, the first extension plate 212 being perpendicular to the inner side surface of the hollow member 211. The guide beam mounting base 3 is connected to the hollow member 211 and the first extension plate 212, respectively, so that the hollow member 211, the first extension plate 212 and the guide beam mounting base form another closed cavity structure 4 except for the cavity of the hollow member 211 at one side of the hollow member 211. In other specific embodiments, a U-shaped groove may be formed on the guide beam mounting seat 3, so that the end of the hollow member 211 can be clamped in the U-shaped groove, and the guide beam mounting seat 3 can have more ribs welded and fixed to three inner sides of the hollow member 211.

In the above example, since the hollow member 211 is a space structure, and the closed cavity structure 4 formed between the hollow member 211, the first extension plate 212 and the guide beam mount 3 has a higher strength than that of the plate-like member of the screw frame in comparison with the prior art in which the guide beam mount is welded to the plate-like member of the screw frame, the mounting strength and safety of the guide beam mount 3 are further improved.

Illustratively, as shown in fig. 6, the hollow member 211 is provided with at least two first mounting holes 2113, preferably two first mounting holes (as shown in fig. 1 to 3 and 7) at equal intervals. The second extension plate 111 provided inside the side frame 11 of the screw frame 1 is provided with at least two second mounting holes 1111 corresponding to the first mounting holes 2113, and fasteners such as screws pass through the first mounting holes 2113 and the second mounting holes 1111 and are fastened into the interface holes on the vehicle body end wall. When the bellows assembly needs to be replaced after a period of time, for example ten years to fifteen years, the connecting piece 2 and the guide beam mounting seat 3 thereon can be separated from the screw frame 1 by disassembling the fastener, and the guide beam mounting seat 3 can be continuously used after the new screw frame 1 is replaced.

Illustratively, the hollow member 211 may be configured as a square tube, the side wall of which has an overlapping portion with the second extension plate 111, thereby increasing the contact area of the screw frame 1 and the connector body 21.

As a specific example in which the guide beam mount 3 is connected to the connector 2, the guide beam mount 3 includes a mount main body 31 and a third extension plate 32 extending outwardly from one end of the mount main body 31. A recess 2112 recessed into the hollow member 211 is provided in the side wall of the hollow member 211 (the side wall attached to the second extension plate 111). The cross section of the recess portion 2112 is rectangular, and the shape thereof is preferably adapted to the cross section shape of the third extension plate 32, so that the contact area of the guide beam mounting seat 3 and the connector 2 can be increased, thereby increasing the connection strength of the two. And a side of the mount main body 31 close to the connection member 2 is welded and fixed to the free end of the first extension plate 212. The first extension plate 212, the third extension plate 32, the hollow member 211 and the mount body 31 thus together define a closed cavity structure 4, and the cavity structure 4 is rectangular in cross section.

As a specific example of the connection member 2 to the body end wall, as shown in fig. 6 and 7, two first mounting holes 2113 are provided at intervals on each hollow member 211, and the guide beam mount 3 is preferably welded to the hollow member 211 and the middle part of the first extension plate 212 in the longitudinal direction, and the two first mounting holes 2113 are provided on both sides of the guide beam mount 3, respectively. Correspondingly, two spaced apart second mounting holes 1111 are formed in the second extension plate 111 of the screw frame 1, and the second mounting holes 1111 are provided in one-to-one correspondence with the first mounting holes 2113. The first and second mounting holes 2113 and 1111 are fitted with the interface hole, and the fastener is screwed into the interface hole through the first and second mounting holes 2113 and 1111 to fix the connector 2 and the screw frame 1 to the body end wall. As shown in fig. 6 and 7, a hole 2111 is provided in a side wall of the hollow member 211 on a side away from the body end wall, and the hole 2111 has a large diameter so as to facilitate the insertion of a tool or hand for the operation of the fastener.

As shown in fig. 1-3, the second extension plate 111 is further provided with a third mounting hole 1112 at a position between the two hollow members 211. Further, the bottom frame 12 and the top frame 13 are respectively provided with a fourth extension plate 121 and a fifth extension plate 131 extending inward, a plurality of fourth mounting holes 1211 and a plurality of fifth mounting holes 1311 are respectively provided in the fourth extension plate 121 and the fifth extension plate 131 at equal intervals, and fasteners can pass through the fourth mounting holes 1211 and the fifth mounting holes 1311, respectively, to directly fix the bottom frame 12 and the top frame 13 of the screw frame 1 to the body end wall.

Further, a sixth extension plate 112 is provided to extend inward from the connection between the side frame 11 and the bottom frame 12 and the top frame 13, and a sixth mounting hole 1121 is provided in the sixth extension plate 112. The screw frame 1 is stably fixed to the vehicle body headwall in the circumferential direction by a plurality of fasteners passing through the second mounting hole 1111 (simultaneously through the first mounting hole 2113 of the hollow member 211), the third mounting hole 1112, the fourth mounting hole 1211, the fifth mounting hole 1311 and the sixth mounting hole 1121, respectively.

The present utility model also provides a through-passage assembly comprising a through-passage and a through-passage connection assembly of each of the above-described exemplary structures for connecting the through-passage to an end wall of a vehicle body. Due to the design of the through channel connecting assembly, the through channel connecting assembly can improve the connecting strength of the through channel, save the manufacturing time and the manufacturing cost and reduce the replacement cost.
