Description

Technical Field

[0001] The present invention belongs to the technical field of rail passenger cars, and more specifically, it relates to a pedal assembly structure between carriages of a rail vehicle. Background Art

[0002] Rail passenger cars usually have two or more carriages. An aisle connection is usually provided between adjacent carriages so that people can move between the two carriages. The pedal assembly is part of the aisle connection, installed at the lower part of the aisle connection, and is generally set to be roughly flush with the floors of adjacent carriages, used to cover the hinge part or gap between the two carriages and for people to walk on. When the vehicle is actually running through various road conditions such as turning, the pedal assembly will undergo single or combined movements such as rotation, stretching or compression, excessive height, roll, and nod, and the movement form is complex. In order to adapt to this complex movement form, a pedal assembly supported by a three-piece four-link mechanism is adopted in the prior art. However, for very complex line conditions, such as sections with "severe curves" with a very small turning radius, this three-piece pedal assembly is still not flexible enough, has insufficient passing ability, cannot achieve the complex movements required by such lines, and is prone to creating gaps between various parts of the pedal assembly, collision interference between pedals, posing a potential risk of injury to passengers, or causing distortion and damage to the pedal assembly, thus there are serious safety hazards. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, to provide a pedal assembly structure between carriages of a rail vehicle with a simple structure, which realizes partial overlap of the pedal assembly and allows relative movement, can move in multiple directions along with the dynamic support frame, allows a larger movement range, realizes more complex movements, can reliably pass through "severe curve" sections with a smaller turning radius, reduces the risk of passengers slipping and being pinched, and improves the overall performance and riding safety of the vehicle.

One end of each support beam is movably mounted on vehicle mounting plate I and extends into vehicle underframe I, and the other end of each support beam is movably mounted on vehicle mounting plate II and extends into vehicle underframe II. Pedal II and pedal IV are respectively connected to corresponding flexible rubber buffers on the central dynamic support structure hoop by bolts IV. Pedal II is configured to be able to move relative to pedal I and the central pedal respectively, pedal IV is configured to be able to move relative to pedal V and the central pedal respectively, and the central pedal is configured to be able to move along with the central dynamic support structure hoop. Rubber buffer stops for limiting are respectively provided on the lower surface of each pedal.

[0006] A part of pedal II is located above pedal I, and this part of pedal II extends to a position below the central pedal. A part of pedal IV is located above pedal V, and this part of pedal IV extends to a position below the central pedal.

[0007] The dynamic support structure hoop member I includes a plurality of hoop assemblies I. One side of the plurality of hoop assemblies I is connected by a flexible rubber connector with a curved surface structure, and the other side of the plurality of hoop assemblies I is connected by a flexible rubber connector with a curved surface structure.

[0008] The dynamic support structure hoop member II includes a plurality of hoop assemblies II. One side of the plurality of hoop assemblies II is connected by a flexible rubber connector with a curved surface structure, and the other side of the plurality of hoop assemblies II is connected by a flexible rubber connector with a curved surface structure.

[0009] Pedal I is fixed on vehicle mounting plate I by bolt I, and pedal V is fixed on vehicle mounting plate II by bolt I.

[0010] A spring is provided between vehicle mounting plate I and dynamic support structure hoop member I, a spring is provided between dynamic support structure hoop member I and the central dynamic support structure hoop, a spring is provided between the central dynamic support structure hoop and dynamic support structure hoop member II, and a spring is provided between dynamic support structure hoop member II and vehicle mounting plate II.

[0011] The central pedal is mounted on the central dynamic support structure hoop by bolt II and bolt III.

[0012] The described pedal assembly structure between tramcar compartments further includes a plurality of rubber buffer stoppers for limiting. A rubber buffer stopper for limiting is installed on the lower surface of Pedal I and extends to the position between the vehicle mounting plate I and the dynamic support structure hoop I. A rubber buffer stopper for limiting is installed on the lower surface of Pedal II and extends to the position between the adjacent hoop assemblies I of the dynamic support structure hoop I.

[0013] A rubber buffer stopper for limiting is installed on the lower surface of Pedal V and extends to the position between the vehicle mounting plate II and the dynamic support structure hoop II. A rubber buffer stopper for limiting is installed on the lower surface of Pedal IV and extends to the position between the adjacent hoop assemblies II of the dynamic support structure hoop I.

[0014] A rubber buffer stopper for limiting is installed on the lower surface of the central pedal and extends to the position between the dynamic support structure hoop I and the central dynamic support structure hoop. A rubber buffer stopper for limiting is installed on the lower surface of the central pedal and extends to the position between the dynamic support structure hoop II and the central dynamic support structure hoop.

[0015] Adopting the technical solution of the present invention, the working principle and beneficial effects are as described below:

[0016] The pedal assembly structure between carriages of the rail vehicle described in the present invention, when setting up the structure, a vehicle mounting plate, a central dynamic support structure hoop, a dynamic support structure hoop member I, a dynamic support structure hoop member II, a support beam, a spring, a rubber buffer stop and a flexible rubber connecting piece jointly form a dynamic support structure. The vehicle mounting plate is installed on the end wall of the vehicle, and the support beam is installed inside the vehicle mounting plate and supports the central dynamic support structure hoop, the dynamic support structure hoop member I and the dynamic support structure hoop member II. The support beam also extends into the vehicle underframe. The central dynamic support structure hoop, the dynamic support structure hoop member I, the dynamic support structure hoop member II, the support beam, the spring and the flexible rubber connecting piece can achieve a certain degree of movement in any direction. In this way, pedal II can move relative to pedal I and the central pedal respectively, pedal IV can move relative to pedal V and the central pedal respectively, and the central pedal can move along with the central dynamic support structure hoop. Pedal II and pedal IV can move along with the corresponding dynamic support structure hoop, and pedal II and pedal IV are installed on rubber buffers, effectively increasing the movement range of the pedals and reducing the movement noise of the pedals. At the same time, the central pedal can move along with the central dynamic support structure hoop, effectively increasing the relative movement range between the central pedal and pedal II and pedal IV. This combination of the pedal assembly increases the relative movement range between the pedals, can achieve more complex movements, and is beneficial for passing through "severe curve" sections. At the same time, the dynamic support structure hoop member I, the dynamic support structure hoop member II and the central dynamic support structure hoop are limited by rubber buffer stops to limit the excessive relative displacement between pedal II, pedal IV and the central pedal, effectively preventing collisions between the pedals and the appearance of gaps, and avoiding passengers from slipping and being pinched. At the same time, each pedal is provided with an inherent anti-slip strip, which can effectively prevent passengers from slipping and is safer. The pedal assembly structure between carriages of the rail vehicle described in the present invention has a simple structure, realizes partial overlap of the pedal assembly and allows relative movement, can move in multiple directions along with the dynamic support frame, allows a larger movement range, realizes more complex movements, reliably passes through "severe curve" sections with a smaller turning radius, reduces the risk of passengers slipping and being pinched, and improves the overall performance and riding safety of the vehicle.

Detailed implementation manners

[0029] The following is a further detailed description of the specific implementation manners of the present invention, such as the shapes, structures, mutual positions and connection relationships between various components, the functions and working principles of each part, etc., with reference to the accompanying drawings and through the description of embodiments:

[0030] As shown in the appendix Figure 1- Attachment Figure 10As shown in the figure, the present invention is a pedal assembly structure between carriages of a rail vehicle. Pedal Ⅰ 1 is fixed on vehicle mounting plate member Ⅰ 6, pedal Ⅴ 5 is fixed on vehicle mounting plate member Ⅱ 21, pedal Ⅱ 2 is carried on dynamic support structure hoop member Ⅰ 7, pedal Ⅳ 4 is carried on dynamic support structure hoop member Ⅱ 11, center pedal 3 is installed on center dynamic support structure hoop 8, and dynamic support structure hoop member Ⅰ 7, dynamic support structure hoop member Ⅱ 11 and center dynamic support structure hoop 8 are respectively connected to support beam 12. One end of each support beam 12 is movably installed on vehicle mounting plate member Ⅰ 6 and extends into vehicle underframe Ⅰ, and the other end of each support beam 12 is movably installed on vehicle mounting plate member Ⅱ 21 and extends into vehicle underframe Ⅱ 22. Pedal Ⅱ 2 and pedal Ⅳ 4 are respectively connected to corresponding flexible rubber buffers 18 on center dynamic support structure hoop 8 through bolts Ⅳ 16. Pedal Ⅱ 2 is configured to be able to move relative to pedal Ⅰ 1 and center pedal 3 respectively, pedal Ⅳ 4 is configured to be able to move relative to pedal Ⅴ 5 and center pedal 3 respectively, and center pedal 3 is configured to be able to move along with center dynamic support structure hoop 8. A rubber buffer stop limit is respectively provided on the lower surface of each pedal. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting up the structure, the vehicle mounting plate, center dynamic support structure hoop, dynamic support structure hoop member Ⅰ, dynamic support structure hoop member Ⅱ, support beam, spring, rubber buffer stop and flexible rubber connection piece jointly form a dynamic support structure. The vehicle mounting plate is installed on the end wall of the vehicle, and the support beam is installed in the vehicle mounting plate and supports center dynamic support structure hoop 8, dynamic support structure hoop member Ⅰ and dynamic support structure hoop member Ⅱ, and the support beam also extends into the vehicle underframe at the same time. Center dynamic support structure hoop, dynamic support structure hoop member Ⅰ, dynamic support structure hoop member Ⅱ, support beam, spring and flexible rubber connection piece can achieve a certain degree of movement in any direction. In this way, pedal Ⅱ 2 can move relative to pedal Ⅰ 1 and center pedal 3 respectively, pedal Ⅳ 4 can move relative to pedal Ⅴ 5 and center pedal 3 respectively, and center pedal 3 can move along with center dynamic support structure hoop 8. Pedal Ⅱ 2 and pedal Ⅳ 4 can move along with the corresponding dynamic support structure hoop, and pedal Ⅱ 2 and pedal Ⅳ 4 are installed on rubber buffers, effectively increasing the movement range of the pedals and reducing the movement noise of the pedals. At the same time, center pedal 3 can move along with center dynamic support structure hoop, effectively increasing the relative movement range between center pedal and pedal Ⅱ, pedal Ⅳ. This combination of the pedal assembly increases the relative movement range between the pedals, can achieve more complex movements, and is beneficial for passing through "severe curve" sections. At the same time, dynamic support structure hoop member Ⅰ, dynamic support structure hoop member Ⅱ and center dynamic support structure hoop are limited by rubber buffer stops, restricting the excessive relative displacement between pedal Ⅱ, pedal Ⅳ 4 and center pedal, effectively preventing collisions between the pedals and the appearance of gaps, and avoiding passengers from slipping and being pinched.At the same time, each pedal is provided with inherent anti-slip strips, which can effectively prevent passengers from slipping and is safer. The pedal assembly structure between the carriages of the rail vehicle described in the present invention has a simple structure, realizes partial overlap of the pedal assembly and allows relative movement, can move in multiple directions along with the dynamic support frame, allows a larger movement range, realizes more complex movements, can reliably pass through the "severe curve" section with a smaller turning radius, reduces the risk of passengers slipping and being pinched, and improves the overall performance and riding safety of the vehicle.

[0031] Part of the pedal II 2 is located above the pedal I 1, and part of the pedal II 2 extends to the position below the central pedal 3. Part of the pedal IV 4 is located above the pedal V 5, and part of the pedal IV 4 extends to the position below the central pedal 3. In the above structure, the pedal includes the pedal I, the pedal II, the central pedal, the pedal IV, and the pedal V. In terms of structural arrangement, the pedal I 1 and the pedal V 5 are respectively fixedly connected to the corresponding vehicle mounting plate members, while the other pedals can move relatively. The above structure of overlapping adjacent pedals not only ensures that the pedals can move relatively, but also ensures that there are no gap parts when the pedals move relatively, thus ensuring the personal safety of passengers.

[0032] The dynamic support structure hoop member I 7 includes a plurality of hoop assemblies I 23. One side of the plurality of hoop assemblies I 23 is connected through a flexible rubber connector 20 with a curved surface structure, and the other side of the plurality of hoop assemblies I 23 is connected through a flexible rubber connector 20 with a curved surface structure. The dynamic support structure hoop member II 11 includes a plurality of hoop assemblies II 24. One side of the plurality of hoop assemblies II 24 is connected through a flexible rubber connector 20 with a curved surface structure, and the other side of the plurality of hoop assemblies II 24 is connected through a flexible rubber connector 20 with a curved surface structure. In the above structure, each dynamic support structure hoop member includes a plurality of hoop assemblies, and the plurality of hoop assemblies are horizontally arranged, ensuring that the dynamic support structure hoop member has a good flexible function during the driving and turning of the vehicle, so as to effectively increase the relative movement range between the central pedal and the pedal II and the pedal IV.

[0033] The pedal I 1 is fixed on the vehicle mounting plate member I 6 through a bolt I 13, and the pedal V 5 is fixed on the vehicle mounting plate member II 21 through a bolt I 13. The vehicle mounting plate member I 6 and the dynamic support structure hoop member I 7 are connected through a spring 9, the dynamic support structure hoop member I 7 and the central dynamic support structure hoop 8 are connected through a spring 9, the central dynamic support structure hoop 8 and the dynamic support structure hoop member II 11 are connected through a spring 9, and the dynamic support structure hoop member II 11 and the vehicle mounting plate member II 21 are connected through a spring 9. In the above structure, each spring plays a role in restricting the range of adjacent components, so as to ensure that the components can move within a certain range and avoid excessive movement range and disengagement.

[0034] The described central pedal 3 is installed on the central dynamic support structure hoop 8 through bolt II 14 and bolt III 15. The structure of the pedal assembly between the carriages of the rail vehicle further includes a plurality of rubber buffer stop limits. A rubber buffer stop limit is installed on the lower surface of pedal I 1 and extends to the position between the vehicle mounting plate member I 6 and the dynamic support structure hoop member I 7. A rubber buffer stop limit is installed on the lower surface of pedal II 2 and extends to the position between the adjacent hoop assemblies I 23 of the dynamic support structure hoop member I 7. A rubber buffer stop limit is installed on the lower surface of pedal V 5 and extends to the position between the vehicle mounting plate member II 21 and the dynamic support structure hoop member II 11. A rubber buffer stop limit is installed on the lower surface of pedal IV 4 and extends to the position between the adjacent hoop assemblies II 24 of the dynamic support structure hoop member I 7. A rubber buffer stop limit is installed on the lower surface of the central pedal 3 and extends to the position between the dynamic support structure hoop member I 7 and the central dynamic support structure hoop 8. A rubber buffer stop limit is installed on the lower surface of the central pedal 3 and extends to the position between the dynamic support structure hoop member II 11 and the central dynamic support structure hoop 8. In the above structure, a plurality of rubber buffer stop limits are provided. Through the rubber buffer stop limits, the excessive relative displacement between pedal II, pedal IV and the central pedal is restricted, effectively preventing the collision between the pedals and the appearance of gaps, and avoiding passengers from slipping and being pinched.

[0035] The pedal assembly structure between carriages of the rail vehicle described in the present invention, when setting up the structure, a vehicle mounting plate, a central dynamic support structure hoop, a dynamic support structure hoop part I, a dynamic support structure hoop part II, a support beam, a spring, a rubber buffer stop and a flexible rubber connecting piece together form a dynamic support structure. The vehicle mounting plate is installed on the end wall of the vehicle, and the support beam is installed inside the vehicle mounting plate and supports the central dynamic support structure hoop, the dynamic support structure hoop part I and the dynamic support structure hoop part II. The support beam also extends into the vehicle underframe at the same time. The central dynamic support structure hoop, the dynamic support structure hoop part I, the dynamic support structure hoop part II, the support beam, the spring and the flexible rubber connecting piece can achieve a certain degree of movement in any direction. In this way, pedal II can move relative to pedal I and the central pedal respectively, pedal IV can move relative to pedal V and the central pedal respectively, and the central pedal can move along with the central dynamic support structure hoop. Pedal II and pedal IV can move along with the corresponding dynamic support structure hoop, and pedal II and pedal IV are installed on rubber buffers, effectively increasing the movement range of the pedals and reducing the movement noise of the pedals. At the same time, the central pedal can move along with the central dynamic support structure hoop, effectively increasing the relative movement range between the central pedal and pedal II and pedal IV. This combination of the pedal assembly increases the relative movement range between the pedals, can achieve more complex movements, and is beneficial for passing through the "severe curve" section. At the same time, the dynamic support structure hoop part I, the dynamic support structure hoop part II and the central dynamic support structure hoop are limited by rubber buffer stops, restricting the excessive relative displacement between pedal II, pedal IV and the central pedal, effectively preventing collisions and gaps between the pedals, and avoiding passengers from slipping and being pinched. At the same time, each pedal is provided with an inherent anti-slip strip, which can effectively prevent passengers from slipping and is safer. The pedal assembly structure between carriages of the rail vehicle described in the present invention has a simple structure, realizes partial overlap of the pedal assembly and allows relative movement, can move in multiple directions along with the dynamic support frame, allows a larger movement range, realizes more complex movements, reliably passes through the "severe curve" section with a smaller turning radius, reduces the risk of passengers slipping and being pinched, and improves the overall performance and riding safety of the vehicle.

Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
