Description

Technical Field:

[0001] The present invention belongs to the technical field of rail transit equipment, and particularly relates to a wall panel device with an occlusion mechanism, which improves the service performance of the gangway by improving the structure. Background Art:

[0002] The wall panel device is an important part of the internal passage of the gangway. It is necessary to protect the side of the internal passage and support the relative movement between vehicles, such as pitching, rolling or rotational movement, or horizontal or vertical displacement. At the same time, the wall panel device also needs to enhance the transition effect visually. In order to balance the requirements of visual beauty and passing through small curved paths, the wall panel devices in the prior art all adopt a single-piece structure, which is pre-assembled and installed as a unit. In order to decouple two vehicles, the entire wall panel device must be disassembled. Due to its own weight, not only a considerable amount of manpower is required, but also complex tools and bracket structures are needed to close the wall panel device during the coupling process, and the service life is relatively low. Therefore, it is necessary to research and design a wall panel device with an occlusion mechanism to reduce the weight, ease the decoupling difficulty, and achieve safety protection. Summary of the Invention:

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, research and design a wall panel device with an occlusion mechanism, reduce the labor intensity, and solve the problem of low service life of the single-piece wall panel device.

[0004] To achieve the above purpose, the main structure of the wall panel device with an occlusion mechanism involved in the present invention includes a wall panel assembly, fixators arranged on both sides thereof, and a support assembly arranged at the bottom; wherein:

[0005] The main structure of the wall panel assembly includes a center plate with a flexible arc structure, a frame arranged at its long side, a cover plate arranged at its short side, and a plurality of stay cables arranged on the back; a plurality of locking mechanisms are arranged on the front of one frame, a guide plate is arranged on the back, and a plurality of fastening elements, hooks and fastening holes are arranged on the back of the other frame; or a plurality of locking mechanisms are arranged on the front of both frames, and guide plates are arranged on the back of both frames;

[0006] The main structure of the locking mechanism includes a lock cover and a lock core arranged therein;

[0007] Moreover, the lock cover is installed on the frame through a locking nut, the lock core is installed in the lock cover through a rubber ring, a locking washer is arranged between the locking nut and the frame, and the inner end face of the lock cover is a bevel;

[0008] The main structure of the fixator includes short cover plates arranged at both ends of the fixator base; a plurality of fixed sleeves arranged in the concave surface of the fixator base, a core shaft passing through the fixed sleeve, and a connecting element arranged on the core shaft; a plurality of mounting seats and torsion springs are arranged on the support panel of the fixator base;

[0009] Specifically, the connecting element consists of several guiding seats, positioning seats and positioning springs. A locking seat is also provided on the guiding seat. The positioning spring is arranged between the positioning sleeve and the positioning seat. An adjusting mechanism is provided on at least one positioning spring. The guiding seat and the positioning seat are connected by a connecting strip. Abrasion strips and positioning plates or center pins are provided on the connecting strip, and guiding grooves are formed on the positioning plates.

[0010] Moreover, the support panel mount is connected by a hinge mount. The mount with at least two stoppers (a first stopper and a second stopper) is connected to a torsion spring. The torsion spring is arranged between the mount and the hinge mount.

[0011] Furthermore, the adjusting mechanism consists of two pluggable and connected adjusting sleeves, one on top of the other.

[0012] The main structure of the support assembly includes a seat plate and a support plate with a V-shaped structure arranged thereon.

[0013] The shielding mechanism is arranged between the wall panel assembly and the vehicle. The main structure includes a fixing plate, a baffle and a brush with inclined backs at both ends of the fixing plate, and a tape and a light strip arranged on the front. The inclined directions of the baffle and the brush are different and have a tendency to intersect.

[0014] The retainer involved in the present invention rotates around the rotation axis formed by two mounts. The torsion spring applies a torque to the retainer to pull the wall panel assembly towards the vehicle connected to the retainer. The convex surface of the retainer rotates around the rotation axis during movement.

[0015] The connecting element rotates around the core shaft and rotatably connects the wall panel assembly to the retainer. At the same time, the guiding seat can move on the core shaft, so that the connecting element and the wall panel assembly connected thereto can move relative to the retainer along the core shaft in the height direction.

[0016] Through the movement of the guiding seat on the core shaft, the wall panel assembly translates relative to the retainer to compensate for the vertical deviation between two vehicles, that is, the height difference that appears in the direction of the rotation axis, including the uneven wear of the wheels of two vehicles or the vertical deviation that appears when the spring states of the main suspension or secondary suspension of the vehicle are different.

[0017] When the wall panel assembly is displaced, the lower edge and the upper edge move parallelly, and the deformation is almost evenly distributed on the cover plate and the short cover plate.

[0018] When the cover plate and the short cover plate collide with the top plate assembly or the floor assembly of the through passage, deformation always occurs. The extension amount of the cover plate and the short cover plate parallel to the height direction is equivalent to 5% to 20% of the dimension of the retainer 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.

[0019] One end of the positioning spring is supported on the fixed sleeve, and the other end is supported on the guide seat. A prestress is applied between the two through an adjusting 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 ends. The acting directions of the two positioning springs are opposite, and reset can be achieved regardless of whether the vertical displacement is a positive displacement or a negative displacement (upward displacement or downward displacement).

[0020] When the vehicle turns, the cable and the torsion spring cooperate together to make the wall panel assembly return to the starting position immediately after the turn is completed. During this period, the wall panel assembly is stretched on the outer side of the turn and compressed on the inner side of the turn.

[0021] Compared with the prior art, the present invention is used inside the transition passage between two interconnected vehicles, and includes a wall panel assembly and fixators arranged on both sides thereof. The fixators are connected to at least one mounting seat through a hinge seat so as to rotate around the mounting seat. The wall panel assembly is respectively hingedly connected to the two fixators so as to rotate around the mandrel and axially slide; the flexible wall panel assembly can realize the functions of quickly locking and unlocking the ends on one side or both sides, has the characteristic of self-restoring after bending, and the shielding mechanism is fixed on the vehicle and is located outside the fixator; its structure is simple. While meeting various motion states between vehicles, the connection effect of the transition area between vehicles is improved, ensuring the safe passage of the drivers and passengers and improving the comfort of the passengers.

The mounting seat 5216 has two stops (the first stop 5218 and the second stop 5219) and is also connected to a torsion spring 5220 arranged on the support panel 5203; caps 5221 are arranged on the two outermost fixing sleeves 5205; a bushing 5222 is arranged between the mandrel 5206 and the guide seat 5207;

[0046] Further, the main structure of the adjusting mechanism 5211 is as shown in Figure 11 the figure, and it is composed of two adjusting sleeves, the upper adjusting sleeve 5231 with an oblong groove 5230 is inserted into the lower adjusting sleeve 5233 with a threaded hole 5232 at the lower part, the oblong groove 5230 and the threaded hole 5232 are connected by a nut bolt 5234, and mounting holes 5235 are formed in both the upper adjusting sleeve 5231 and the lower adjusting sleeve 5233;

[0047] The main structure of the support assembly 53 is as shown in Figure 4 the figure, and it includes a seat plate 530, a support plate 531 and a fixing hole 532; a support plate 531 with a V-shaped structure is arranged on the seat plate 530, the support plate 531 is arranged on the seat plate 530 through a fastener 100, a fixing hole 532 is formed at the top thereof, and the bottom of the wall plate assembly 51 is connected to the fixing hole 532 of the support assembly 53 through the fastener 100;

[0048] The main structure of the shielding mechanism 6 is as Figure 12-13 shown, including a fixing plate 61, angle plates 62, a baffle 63, a brush 64, a tape 65, and a light strip 66; angle plates 62 are provided at both ends of the fixing plate 61, the baffle 63 and the brush 64 are obliquely arranged on the back, and the tape 65 and the light strip 66 are provided on the front; the angle plates 62 are arranged on the fixing plate 61 through fasteners 100, and the baffle 63 and the brush 64 have different oblique directions and tend to intersect.

[0049] The wall panel assembly 51 and the fixture 52 involved in this embodiment both weigh less than 20 kg, and are assembled and processed separately, meeting 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 composition must be hoisted or assembled at one time. The total weight of the traditional pre-assembled wall panel composition is large and does not meet the requirement of one-person operation specified by the specification);

[0050] The center plate 510 is a thermosetting plate made of synthetic resin, with glass fibers embedded therein, and has the characteristics of high strength and high fire resistance and flame retardancy. It includes a thermosetting plate made of synthetic resin, with glass fibers embedded therein, and is adhesively fixed to the connection with the frame 511 through a coating adhesive 518. When an information carrier plate for displaying information (including passenger information or advertisement information) is provided on the outside of the center plate 510, a transparent plastic plate is provided on the outermost side so that the information carrier plate (such as a printed poster) between the plastic plate and the center plate 510 can be clearly visible. The plastic plate can not only fix the information carrier plate but also protect it from the outside;

[0051] The frame 511 is a lightweight metal strip, and the end 5110 is cleverly matched with the boss 5270 provided on the guide seat 5207, as Figure 14 shown, effectively improving the connection strength between the wall panel assembly 51 and the fixture 52, and improving the reliability of the wall panel assembly 51. The frame 511 also has an extension part 5113 that covers the mandrel 5206, the fixing sleeve 5205, and the guide seat 5207, so that the gap between the arc part of the outer convex surface 5111 and the inner concave surface 5202 of the fixture 52 is as small as possible;

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

[0053] The locking mechanism 514 and the fastening element 516 are fixedly penetrated with the frame 511 together for connecting the wall panel assembly 51 and the fixture 52;

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

[0055] The guide seat 5207 completely surrounds the mandrel 5206, and a bushing 5222 made of plastic material is provided therebetween. The bushing 5222 is press-fitted into the guide seat 5207. Axial grooves are provided on the inner side of the bushing 5222, which can not only enable the guide seat 5207 to rotate freely around the mandrel 5206, but also enable the guide seat 5207 to translate smoothly along the mandrel 5206;

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

[0057] The mounting seat 5216 has at least three connection positions, such as Figure 15 shown. The first connection position is connected to the vehicle 7. The second connection position is arc-shaped and is rotatably connected to the fixture 52 through the hinge seat 5217. 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 end fixing sleeves 5205 so as to fix the mandrel 5206 in the fixing sleeve 5205;

[0060] The baffle 63 is a flexible structure to prevent passengers from inserting their fingers into the gap between the convex outer surface 5201 and the vehicle 7;

[0061] The brush 64 acts as a shield in the gap between the convex outer surface 5201 and the vehicle;

[0062] The light strip 66 is preferably an LED light strip to illuminate the transition area;

[0063] In addition, both the cover plate 512 and the short cover plate 5204 are made of elastic rubber and are deformable. The edges of the wall plate assembly 51 and the fixture 52 are flush in the height direction. When a vertical displacement occurs, part of the vertical displacement is absorbed by the cover plate 512 and the short cover plate 5204.

[0064] The wall plate assembly 51 involved in this embodiment can be quickly and conveniently connected to the connecting element, making the assembly easier. The two fixtures 52 are separately connected to each other, and the entire wall plate assembly 5 does not need to be assembled as a whole:

[0065] First, a frame 511 is connected to the connecting element through a fastening element 516 passing through the fastening hole 5112. Since the wall plate assembly 51 can rotate around the mandrel 5206, the fastening element 516 is installed by means of the positioning function of the center pin 5200 and the hook 517;

[0066] Then, the other frame 511 is moved toward the holder 52 or the connecting element, and since the wall panel assembly 51 can rotate around the core shaft 5206, the wall panel assembly 51 is connected or unlocked through the locking mechanism 514 by means of the guiding function of the guide plate 515 inserted into the guide groove 5215;

[0067] Finally, inside the vehicle 7, i.e., on the passenger side, a tool is used to rotate the lock core 5143 so that the lock core 5143 is screwed into or out of the lock seat 5210, and the wall plate assembly 51 is connected and separated from the connecting element. The interaction between the inner wall and the inclined surface 5147 provided inside the lock cover 5141 and the rubber ring 5144 can ensure that the lock core 5143 is centered during the process of being released and connected in the unlocked state.

[0068] When connecting and disconnecting the vehicle 7, using this connection method can ensure that the wall panel assembly 5 can be installed and disconnected quickly and easily.

[0069] When the wall panel device with a shielding mechanism involved in this embodiment is used, the wall panel component 5 is connected to the end of the vehicle 7 through the mounting seat 5216, and the shielding mechanism 6 is fixedly installed at the end of the vehicle 7 through the angle plate 62;

[0070] When the wall panel component 5 is in the initial position, Figure 16 As shown: the two vehicles 7 do not have relative movement, the first stop 5218 and the second stop 5219 limit the rotational movement of the fixer 52 around the rotation axis, in one rotational direction, the first stop 5218 contacts the support panel 5203, and in the other rotational direction, the second stop 5219 contacts the first limiting surface 5300 of the counter-stop formed by the support panel 5203, preventing the fixer 52 from excessive rotational movement around the rotation axis, based on this, when the wall panel assembly 5 is in the initial position, the fixer 52 can rotate freely in two rotational directions, and the wall panel assembly 51 can rotate around the core shaft 5206. Due to the tensioning effect of the cable 513 or the torsion spring 5220 on the wall panel assembly 51, the wall panel assembly 51 bends outward (in the direction of the center of the channel) at the initial position, and the rotation of the connecting element around the core shaft 5206 is self-adjusted for the first time.

[0071] When the wall panel component 5 is in the compressed position, Figure 17 As shown: due to the relative movement between the vehicles 7, the mounting seats 5216 on both sides approach each other, and the fixture 52 rotates around the rotation axis. When the first stop 5218 contacts the support panel 5203, the rotation movement reaches the limit. At the same time, the connecting element rotates outward around the core shaft 5206, partially compensating for the rotation movement of the fixture 52. The rotation of the connecting element around the core shaft 5206 is self-adjusted again. Based on this, the wall panel assembly 51 is more bent in the compressed position than the initial position. The approach of the vehicle or the mounting seat 5216 is compensated by further rotation movement of the connecting element and further bending of the wall panel assembly 51.

[0072] When the wall panel assembly 5 is in the extended position, as Figure 18 shown: The vehicle 7 or the mounting seat 5216 move away from each other through the relative movement of the vehicle 7, that is, the distance between the mounting seats 5216 is greater than the initial position. The retainer 52 rotates around the rotation axis in a direction opposite to the compressed position. The second stop 5219 contacts the first limiting surface 5300, and the retainer 52 no longer rotates further. The two stop surfaces contact each other, and the rotational movement of the retainer 52 can be restricted regardless of the rotation direction. The connecting element rotates inward relative to the initial position, partially compensating for the movement of the mandrel 5206, so that the wall panel assembly 51 still has a curvature. Starting from the illustrated position, if the vehicles 7 need to move further apart, the length of the extended cable 513 is compensated by further rotating the connecting element, and the curvature of the wall panel assembly 51 is reduced; during the extension of the wall panel assembly 5, the vehicle 7 or the mounting seat 5216 generates a lateral displacement perpendicular to the running direction of the train through the relative movement of the vehicle, and there is a difference from the torsion of the torsion spring 5220. The rotation angles between the retainers 52 are not synchronized, resulting in noise or excessive wear due to 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 mandrel 5206 moves along a circumferential trajectory around the rotation axis, compensating for a part of the change in the distance between the vehicle 7 or the fixed seat 5216. Another part of the change in the distance between the vehicle 7 or the fixed seat 5216 is compensated by the rotation of the connecting element around the mandrel 5206, combined with the change in the curvature of the wall panel assembly 51.

A wall panel device with a shielding mechanism according to claim 3, characterized in that: The screw connection combined with the locking mechanism simplifies the assembly and disassembly of the wall assembly, as well as the connection or removal of the vehicle: The connecting element is connected to the wall panel assembly by at least one threaded connection, and the threaded connection is a detachable connection, which can be connected or separated by a screwdriver or a similar tool, so that the wall panel assembly can be assembled and disassembled quickly and easily; The connecting element is connected to the wall panel assembly through at least one locking mechanism, and the locking mechanism can quickly establish or disconnect the connection between the wall panel assembly and the connecting element by driving the lock cylinder, and quickly disconnect the connection between the fastener and the wall panel assembly when connecting or disconnecting the vehicle; During the initial assembly process, the wall panel assembly is connected to the connecting element using a screw connection. Since the wall panel assembly can be rotated around the core axis, the wall panel assembly can be conveniently installed on the side that is not visible to the passengers by turning out the wall panel assembly, similar to opening a door. Then, the wall panel assembly is connected to the connecting element of another fixture through a locking mechanism; When coupling or unlocking, there is no need to loosen the screw connection, just loosen the locking mechanism and the vehicles can be separated from each other; The locking mechanism includes a lock core, which can be accessed from the side of the wall panel assembly facing the passenger. The wall panel assembly is installed and removed by rotating the lock core installed on the wall panel assembly and screwing the lock seat installed on the connecting element in and out. There is a safety mark on the lock cover indicating that it is locked in place.

7. A wall panel device with a shielding mechanism according to claim 1 or 2, characterized in that: The wall panel assembly includes a flexible center panel, two side frames, two long cover panels, a guide plate, at least three locking mechanisms, a set of support mechanisms, and three sets of cables; The two frames are fixedly connected to the long sides of the center plate, the frame on the locking side is provided with a locking mechanism, and the frame on the non-locking side is provided with a hook, so as to facilitate the connection between the wall panel assembly and the connecting element; The two cover plates are fixedly connected to the short sides of the center plate; The guide plate is fixedly connected to the frame on the locking side and plays a guiding role when the wall panel assembly is locked; The locking mechanism is fixed to the frame on the locking side in a through-type manner and is evenly arranged in the height direction of the frame; The support mechanism is fixed at the short side end of the bottom of the center plate, so that the wall panel assembly can be supported on the vehicle floor after opening, and the lower cover plate can be protected from excessive extrusion. A non-metallic seat plate is provided at the position where the support mechanism contacts the vehicle floor. The two ends of the cable are fixedly connected to the two frames respectively. The cable pre-tensions the center plate so that it arches to the side opposite to the core axis at the initial position, ensuring that the wall panel assembly is always in a tensile bending state, and continues to arch in the same direction when the vehicles move relative to each other, without being separated from the frames, and enables the center plate to form an area with high rigidity and load-bearing capacity, an area that can be bent, stretched or compressed, thereby compensating for the elongation or shortening of the wall panel assembly when the vehicles move relative to each other; The central panel is made of a thermosetting material including synthetic resin, reinforced by glass fiber fabric mats, has fire resistance, meets the requirements of EN45545, and provides a large homogeneous surface that can be used to display information including advertising information or timetable information.

8. A wall panel device with a shielding mechanism according to claim 1 or 2, characterized in that: The upper and lower edges of the holder in the direction of the rotation axis are provided with elastically deformable short cover plates, and the wall plate assembly is provided with elastically deformable cover plates on the upper and lower edges in the direction of the rotation axis to absorb the relative movement of the vehicle parallel to the rotation axis; When the vehicles move relative to each other parallel to the axis of rotation and there is a vertical offset between the two vehicles, the elastically deformable short cover plate and the cover plate are made of rubber and adapt to the vertical offset in the upward and downward directions by deformation. Since the wall panel assembly is connected to the core shaft, it can translate to allow the retainer and the wall panel assembly to slide along the core shaft, ensuring that the deformation is evenly distributed between the cover plate and the short cover plate, so that they bear the same load and extend the maintenance cycle.

9. A wall panel device with a shielding mechanism according to claim 3, characterized in that: The shielding mechanism is fixed on the vehicle and includes at least one fixing frame composed of a special-shaped plate structure or a special-shaped track, and a strip brush is connected to one end of the fixing frame to cover the gap between the fixing device and the vehicle to protect passengers from injury; When an additional light source is needed to illuminate the transition section between two vehicles so that when passing through a tunnel or driving in the dark, the transition section is still sufficiently illuminated and the cable is laid as simply as possible so that it is not affected by relative movement. The light source is integrated or bonded in the groove of the fixing bracket. The light source includes an LED strip light.

10. A wall panel device with a shielding mechanism according to claim 9, characterized in that: Applied to the inner side of a through-tunnel arranged between two vehicles connected to each other in an articulated manner, the two fixtures are directly or indirectly connected to the two vehicles through mounting seats and generate relative movement following the movement of the vehicles; The holder is rotatably connected to the vehicle through the mounting seat, the guide plate is inserted into the guide groove of the positioning plate, and the wall panel assembly is connected to the holder through the connecting element and the locking mechanism; Rotating the wall plate assembly about the mandrel and rotating the fixture about the rotation axis, when the fixture rotates, at least a torque of a torsion spring is overcome, and the torque counteracts the relative movement between the fixtures; When locking, the wall panel assembly rotates in an open-door manner around the rotation axis. After the wall panel assembly is positioned through the rotational movement, most of the distance between the vehicles is covered, and there is only a small distance between the wall panel assembly and the parts on the vehicle used to fix the wall panel assembly. At this time, rotate the fastener in the direction of the wall panel assembly until the gap disappears, reaching the locked closed position, and completing the locking operation.
