Description

Technical fields:

[0001] This utility model belongs to the field of rail transit equipment technology, specifically relating to a through passage device that improves the performance of the through passage by modifying the structure of the wall panels. Background technology:

[0002] With the rapid development of the rail transit industry, the types of rail vehicles are gradually increasing. As a crucial component connecting the vehicle bodies, the structure of the connecting passageway is also constantly evolving to meet diverse road conditions. The wall panel assembly, a vital part of the internal passageway, needs to provide lateral protection and support relative movement between vehicles, such as pitching, rolling, or rotational movements, or horizontal or vertical displacement. Simultaneously, the wall panel assembly must visually enhance the transition effect. To balance aesthetics and the requirements of navigating small curves, existing connecting passageway wall panel assemblies are all single-piece structures, pre-assembled and installed as a unit. To uncouple two vehicles, the entire wall panel assembly must be disassembled. Due to its weight, this requires considerable manpower, complex tools, and support structures to close the wall panel assembly during coupling, resulting in a short service life. Therefore, it is necessary to develop and design a connecting passageway device that reduces the weight of the wall panel assembly, simplifies uncoupling, and achieves safe protection. Summary of the Invention:

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, develop and design a through-channel device, simplify installation and unlocking operations, reduce labor intensity, and solve the problem of short lifespan of single-piece wall panels.

[0004] To achieve the above objectives, the main structure of the through passage device involved in this utility model includes a folding canopy and a top plate arranged on its upper surface, a floor arranged on its lower surface, and wall panels arranged on both sides.

[0005] The main structure composed of wall panels includes wall panel assemblies, fasteners on both sides, and support assemblies at the bottom; wherein:

[0006] The main structure of the wall panel assembly includes a flexible arc-shaped center plate and a frame set along its long side, a cover plate set along its short side, and several pull cables set along its back; several locking mechanisms are set on the front of one frame and a guide plate is set on the back, and several fastening elements, hooks and fastening holes are set on the back of the other frame; or several locking mechanisms are set on the front of both frames and guide plates are set on the back of both frames.

[0007] The main structure of the locking mechanism includes the lock cover and the lock cylinder installed inside it;

[0008] Furthermore, the lock cover is installed on the frame by a lock nut, the lock cylinder is installed inside the lock cover by a rubber ring, a lock washer is provided between the lock nut and the frame, and the inner end face of the lock cover is beveled.

[0009] The main structure of the fastener includes short cover plates at both ends of the fastener base; several fixing sleeves in the concave surface of the fastener base, a mandrel passing through the fixing sleeves, and connecting elements on the mandrel; and several mounting seats and torsion springs on the support panel of the fastener base.

[0010] Specifically, the connecting element consists of several guide seats, positioning seats and positioning springs. The guide seats are also provided with locking seats. The positioning springs are located between the positioning sleeve and the positioning seats. At least one positioning spring is provided with an adjustment mechanism. The guide seats and positioning seats are connected by a connecting strip. The connecting strip is provided with a wear strip and a positioning plate or center pin. The positioning plate is provided with a guide groove.

[0011] Furthermore, the support panel and the mounting base are connected by a hinge, and the mounting base, which has at least two stops (a first stop and a second stop), is connected to a torsion spring, which is located between the mounting base and the hinge.

[0012] Furthermore, the adjustment mechanism consists of two plug-in adjustable sleeves;

[0013] The main structure of the support assembly includes a base plate and a V-shaped support plate mounted on it.

[0014] When the number of folding structures involved in this utility model is two, a separating component can be added between the two.

[0015] The present invention relates to a fastener that rotates around a rotation axis formed by two mounting seats. A torsion spring applies torque to the fastener to pull the panel assembly toward the vehicle connected to the fastener. The outer convex surface of the fastener rotates around the rotation axis during the movement.

[0016] The connecting element rotates about the spindle and rotatably connects the wall panel assembly to the fixture, while the guide seat is movable on the spindle, thereby allowing the connecting element and the wall panel assembly connected thereto to move along the spindle relative to the fixture in the height direction.

[0017] By moving the guide seat on the spindle, the panel assembly translates relative to the retainer to compensate for the vertical deviation between the two vehicles, i.e., the height difference that occurs in the direction of the rotation axis. This includes vertical deviations that occur when the wheels of the two vehicles are worn unevenly, or when the spring states of the main suspension or secondary suspension of the vehicles are different.

[0018] When the wall panel assembly is displaced, the lower and upper edges move in parallel, and the deformation is distributed almost evenly on the cover plate and the short cover plate.

[0019] When the cover plate and short cover plate collide with the top plate assembly or the floor assembly, deformation will always occur. The extension of the cover plate and short cover plate in the height direction is equivalent to 5% to 20% of the dimension of the fastener in the same direction. After one side of the wall panel assembly is opened, the support assembly plays a supporting role to avoid damage to the cover plate at the lower edge.

[0020] One end of the positioning spring is supported on the fixed sleeve, and the other end is supported on the guide seat. Prestress is applied between the two by the adjustment mechanism so as to position the wall panel assembly along the mandrel or restore the wall panel assembly to the initial position after the vertical displacement is completed. The two positioning springs act in opposite directions, so the reset can be achieved regardless of whether the vertical displacement is positive or negative (upward or downward).

[0021] When the vehicle turns, the cable and torsion spring work together to return the panel assembly to its starting position immediately after the turn is completed. During this process, the panel assembly is stretched on the outside of the turn and compressed on the inside of the turn.

[0022] Compared with the prior art, this utility model provides a transition area between two interconnected vehicles, comprising at least a canopy assembly and its internal top plate assembly, bottom floor assembly, and side wall panel assemblies. Each wall panel assembly includes two retainers and a wall panel component positioned between them. The retainers are connected to at least one mounting base via hinged joints, allowing rotation around the mounting base. The flexible wall panel component is hinged at both ends to the retainers, allowing rotation around a spindle and axial sliding. One or both ends of the bendable wall panel component have quick locking and unlocking functions. When the vehicle passes through a curve, the outer distance increases while the inner distance decreases. The center plate of the wall panel component has the characteristic of self-recovery after bending, and the wall panel component is connected to the retainers without wear, while also reducing overall weight. Its structure is simple, the wall panel component can be easily replaced, simplifying installation and disassembly steps, reducing the labor intensity of closing or opening the wall panel component when connecting vehicles, and reducing the required time.

Three guide seats 5207, two positioning seats 5208, and two positioning springs 5209 are provided on the spindle 5206. A locking seat 5210 is provided on the guide seat 5207. A positioning spring 5209 is located between the positioning sleeve 5205 and the positioning seat 5208. One of the positioning springs 5209 is provided with an adjusting mechanism 5211. The guide seat 5207 and the positioning seat 5208 are connected by a connecting bar 5212. Wear strips 5213 are provided at both ends of the connecting bar 5212. A positioning plate 5214 is provided in the middle of one connecting bar 5212, and a center pin 52 is provided in the middle of the other connecting bar 5212. 00, the positioning plate 5214 has a guide groove 5215; the support panel 5203 is provided with a mounting base 5216, the two are connected by a hinge base 5217, the mounting base 5216 has two stops (first stop 5218 and second stop 5219), and is also connected to a torsion spring 5220 provided on the support panel 5203; the two outermost fixing sleeves 5205 are provided with caps 5221; a bushing 5222 is provided between the spindle 5206 and the guide seat 5207;

[0047] Furthermore, the main structure of the regulating mechanism 5211 is as follows: Figure 12 As shown, it consists of two adjusting sleeves, an upper adjusting sleeve 5231 with an elongated groove 5230 and a lower adjusting sleeve 5233 with a threaded hole 5232. The elongated groove 5230 and the threaded hole 5232 are connected by a nut 5234. Both the upper adjusting sleeve 5231 and the lower adjusting sleeve 5233 are provided with mounting holes 5235.

[0048] The main structure of the support component 53 is as follows Figure 5 As shown, it includes a base plate 530, a support plate 531, and a fixing hole 532; the base plate 530 is provided with a V-shaped support plate 531, which is mounted on the base plate 530 by fasteners 100, and a fixing hole 532 is provided on its top. The bottom of the wall panel assembly 51 is connected to the fixing hole 532 of the support assembly 53 by fasteners 100.

[0049] The wall panel assembly 51 and the fastener 52 involved in this embodiment weigh less than 20 kg each, and they are assembled and processed separately, which meets the requirements of one-time hoisting or assembly, and one person can complete the operation (the prior art stipulates that the entire pre-assembled wall panel assembly must be hoisted or assembled at one time, and the total weight of the traditional pre-assembled wall panel assembly is large, which cannot meet the requirement of one person to operate).

[0050] The center plate 510 is a thermosetting board made of synthetic resin with embedded glass fiber. It has the characteristics of high strength and high fire resistance. It is bonded and fixed to the frame 511 by applying adhesive 518. When an information carrier board for displaying information (including passenger information or advertising information) is set on the outside of the center plate 510, a transparent plastic plate is set on the outermost side so that the information carrier board (such as printed poster) between the plastic plate and the center plate 510 can be clearly seen. The plastic plate can both fix the information carrier board and protect it from external influences.

[0051] The frame 511 is a lightweight metal strip, and its end 5110 cleverly matches the protrusion 5270 on the guide seat 5207, such as... Figure 13 As shown, the connection strength between the wall panel assembly 51 and the fastener 52 is effectively improved, and the reliability of the wall panel assembly 51 is enhanced. The frame 511 also has an extension 5113 that covers the spindle 5206, the fixing sleeve 5205 and the guide seat 5207, so that the gap between the arc-shaped part of its convex surface 5111 and the concave surface 5202 of the fastener 52 is as small as possible.

[0052] Three parallel cables 513 pre-tension the wall panel assembly 51, causing the wall panel assembly 51 to be compressed or bent, and to be arc-shaped in the initial position.

[0053] Locking mechanism 514 and fastening element 516 are through-fixed to frame 511 for connecting panel assembly 51 and fixture 52;

[0054] The mandrel 5206 can be a cylindrical structure, a tubular structure, or a rod-shaped structure, and is connected to the base of the fixture 52 via a fixing sleeve 5205;

[0055] The guide seat 5207 completely surrounds the spindle 5206, and a plastic bushing 5222 is provided between the two. The bushing 5222 is pressed into the guide seat 5207. An axial groove is provided on the inner side of the bushing 5222, which allows the guide seat 5207 to rotate freely around the spindle 5206 and to move smoothly along the spindle 5206.

[0056] Wear strip 5213 is made of non-metallic wear-resistant material;

[0057] Mounting bracket 5216 has at least three connection positions, such as Figure 14 As shown, the first connection position is connected to the vehicle 7, the second connection position is arc-shaped and is rotatably connected to the retainer 52 through the hinge seat 5217, and the third connection position is connected to the torsion spring 5220.

[0058] The torsion spring 5220 can be replaced by a helical spring;

[0059] The cap 5221 closes the outer ends of the two fixing sleeves 5205 so as to fix the spindle 5206 in the fixing sleeves 5205;

[0060] In addition, both cover plate 512 and short cover plate 5204 are made of elastic rubber and are deformable. The edges of the wall panel assembly 51 and the retainer 52 are flush in the height direction. In the event of vertical displacement, part of the vertical displacement is absorbed by cover plate 512 and short cover plate 5204.

[0061] The wall panel assembly 51 involved in this embodiment can be quickly and easily connected to the connecting elements, making assembly easier. The two fasteners 52 are connected separately, and the entire wall panel assembly 5 does not require overall assembly.

[0062] First, a frame 511 is connected to the connecting element through a fastening element 516 passing through a fastening hole 5112. Since the wall panel assembly 51 can rotate around the spindle 5206, the fastening element 516 is installed by means of the positioning function of the center pin 5200 and the hook 517.

[0063] Then, another frame 511 is moved toward the retainer 52 or connecting element. Since the wall panel assembly 51 can rotate around the spindle 5206, the wall panel assembly 51 is connected or unlocked by the locking mechanism 514 by means of the guiding function of the guide plate 515 inserted into the guide groove 5215.

[0064] Finally, inside the vehicle 7, i.e. on the passenger side, a tool is used to rotate the lock cylinder 5143, causing the lock cylinder 5143 to be screwed into or out of the lock seat 5210, thereby connecting and separating the wall panel assembly 51 from the connecting element. The interaction between the inner wall and the inclined surface 5147 inside the lock cover 5141 and the rubber ring 5144 ensures that the lock cylinder 5143 remains centered during the disengagement and connection process in the unlocked state.

[0065] Using this connection method when connecting and disconnecting vehicle 7 ensures quick and easy installation and disconnection of the wall panel assembly 5.

[0066] In this embodiment, a through-passage device is used in which the wall panel assembly 5 is connected to the end of the vehicle 7 via the mounting base 5216.

[0067] When panel 5 is in its initial position, as follows: Figure 15As shown: There is no relative movement between the two vehicles 7. The first stop 5218 and the second stop 5219 restrict the rotational movement of the retainer 52 around the rotation axis. In one rotational direction, the first stop 5218 contacts the support panel 5203. In the other rotational direction, the second stop 5219 contacts the first limiting surface 5300 of the anti-stop block formed by the support panel 5203, preventing the retainer 52 from excessive rotational movement around the rotation axis. Based on this, when the wall panel assembly 5 is in the initial position, the retainer 52 can rotate freely in both rotational directions, and the wall panel assembly 51 can rotate around the spindle 5206. Due to the tension of the cable 513 or the torsion spring 5220 on the wall panel assembly 51, the wall panel assembly 51 bends outward (towards the center of the channel) in the initial position, and the rotation of the connecting element around the spindle 5206 is self-adjusted for the first time.

[0068] When panel component 5 is in the compressed position, such as Figure 16 As shown: Due to the relative movement between the vehicles 7, the mounting seats 5216 on both sides move closer to each other, and the retainer 52 rotates around the rotation axis. When the first stop 5218 contacts the support panel 5203, the rotational movement reaches its limit. At the same time, the connecting element rotates outward around the spindle 5206, partially compensating for the rotational movement of the retainer 52. The rotation of the connecting element around the spindle 5206 is self-adjusted again. Based on this, the wall panel assembly 51 is more bent in the compressed position than in the initial position. The approach of the vehicles or mounting seats 5216 is compensated by the further rotational movement of the connecting element and the further bending of the wall panel assembly 51.

[0069] When panel 5 is in the extended position, such as Figure 17As shown: Vehicle 7 or mounting base 5216 move away from each other due to the relative movement of vehicle 7, i.e., the distance between mounting bases 5216 is greater than the initial position. Fixture 52 rotates about the rotation axis in the opposite direction to the compressed position. The second stop 5219 contacts the first limiting surface 5300, and fixture 52 no longer rotates further. The two stopping surfaces contact each other, limiting the rotational movement of fixture 52 regardless of the direction of rotation. The connecting element rotates inward relative to the initial position, partially compensating for the movement of spindle 5206, thus allowing the wall panel assembly 51 to retain its curvature. Starting from the position shown in the diagram, if the vehicles 7 need to move further apart, the length of the cable 513 is increased and the curvature of the wall panel assembly 51 is reduced by further rotating the connecting element to compensate. During the elongation of the wall panel assembly 5, the vehicles 7 or the mounting base 5216 generate a lateral displacement perpendicular to the direction of train operation due to the relative movement of the vehicles. This difference in torque with the torsion spring 5220 causes the rotation angles between the fixtures 52 to be asynchronous, resulting in noise or excessive wear caused by the contact friction between the hinge seat 5217 and the connecting element. This defect is compensated by the contact between the limiting surface 5400 of the hinge seat 5217 and the wear strip 5213. The spindle 5206 moves around the rotation axis along a circumferential trajectory to compensate for part of the distance change between the vehicles 7 or the mounting base 5216. The other part of the distance change between the vehicles 7 or the mounting base 5216 is compensated by the rotation of the connecting element around the spindle 5206, combined with the change in the curvature of the wall panel assembly 51.
