Description

Technical Field

[0001] The present application relates to the technical field of rail vehicle safety, and in particular to a retracting device for a rail vehicle driver's seat. Background Art

[0002] The driving safety of rail vehicles has always been a matter of general concern to the public, especially the accidental collision of fast-moving passenger vehicles, which is bound to cause major safety accidents. In order to minimize the losses caused by accidents, people have gradually realized the importance of fully considering the collision resistance of vehicles when designing vehicles.

[0003] In recent years, the passive protection technology that has emerged internationally has achieved the goal of protecting the lives of passengers to the greatest extent possible by designing the crash resistance of trains, so that the energy absorption device can absorb the collision kinetic energy in an orderly manner and convert it into plastic deformation energy when the vehicle collides. This design concept has been widely accepted by various countries and has begun to be applied in my country's rail vehicles. However, due to the unexpectedness of accidents, the collision speed is often greater than the designed capacity of the energy absorption device, resulting in safety issues such as driver casualties due to the compression of the driver's living space. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a retraction device for a rail vehicle driver's seat, which utilizes the retraction action of the anti-climbing energy absorption component in a collision to drive the driver's seat to retreat synchronously when a collision occurs, away from the end of the vehicle that has been deformed by the collision, thereby providing the driver with a larger survival space in a collision accident and increasing the driver's probability of survival.

[0038] like Figures 1 to 4As shown, an embodiment of the present invention provides a retraction device for a rail vehicle driver's seat, comprising an anti-climbing energy absorption component 100; a slidable seat 300 with a safety belt 313 and a retraction guide device 200. The retraction guide device 200 comprises an anti-climbing traction rod 210 connected to the anti-climbing energy absorption component 100; a guide seat 220 installed at one end of the anti-climbing traction rod 210 away from the anti-climbing energy absorption component 100; and a retraction guide rod 230 connected to the guide seat 220 at one end and connected to the slidable seat 300 with a safety belt 313 at the other end.

[0039] The retraction device for the driver's seat of a rail vehicle provided in an embodiment of the present invention is such that when the rail vehicle collides, the anti-climbing energy absorbing assembly 100 is compressed and deformed to absorb the impact kinetic energy, while driving the anti-climbing traction rod 210 connected to the anti-climbing energy absorbing assembly 100 to move backward, so that the retraction guide rod 230, under the guidance of the guide seat 220 connected to the anti-climbing traction rod 210, pushes the slidable seat 300 with the safety belt 313 to slide backward at the same time, and the safety belt and the seat bring the person away from the front end, thereby away from the end of the vehicle that has collided and deformed, thereby providing the driver with a larger living space in a collision accident and increasing the driver's probability of survival.

[0040] As a preferred implementation mode of the embodiment of the present invention, the slidable seat 300 with a safety belt 313 in the embodiment of the present invention may also include a base 310 for installing the seat 300 with a safety belt 313; a guide rail 500 installed on the cab frame 400, and the base 310 can slide on the guide rail 500.

[0041] The base 310 is a seat-shaped structure composed of multiple metal plates, located behind the seat retraction guide rod 230, bolted under the seat 330, and slidable with a safety belt 313. When the seat 300 retracts, the guide rail 500 formed on the cab frame 400 can control the retraction direction of the seat 300.

[0042] As a preferred implementation of the embodiment of the present invention, the retracting device of the rail vehicle driver seat provided in the embodiment of the present invention further includes a shear block 320 sleeved on the guide rail 500, and the base 310 is installed on the shear block 320. The shear block 320 includes a first shear plate 321 and a second shear plate 322 located above the first shear plate 321, and the first shear plate 321 and the second shear plate 322 are connected by a connecting member so that a space for accommodating the guide rail 500 is formed between the first shear plate 321 and the second shear plate 322.

[0043] The shear block 320 is a metal wedge-shaped structure, located below the sliding base 310 of the seat 300 with the safety belt 313, installed in the guide rail on the cab chassis 400, and connected to the cab chassis 400 through the shear pin. When the load transmitted from the sliding base 310 exceeds the load limit of the shear pin, the shear block 320 is released from the sliding base 310, and the seat 300 with the safety belt 313 slides back, preventing the seat 300 from being retracted in conjunction with the daily load.

[0044] As a preference, the base 310 in the embodiment of the present invention includes a mounting portion 311 for mounting a seat 300 with a safety belt 313, wherein the mounting portion 311 is capable of sliding on the guide rail 500; a connecting portion 312 connected to the mounting portion 311, and a retraction guide rod 230 is connected to the connecting portion 312.

[0045] As a preferred structure of an embodiment of the present invention, the guide seat 220 includes a horizontal part that is mounted on the guide rail 500; a vertical part connected to the horizontal part, one side of the vertical part is connected to the retraction guide rod 230, and the other side of the vertical part is connected to the anti-climbing traction rod 210.

[0046] As a preferred structure of the embodiment of the present invention, the front peripheral side wall of the cab chassis 400 is longitudinally extended to form a guardrail 600, and hollow parts are opened on both sides of the guardrail 600. The guardrail 600 can prevent the driver from being injured when the front end of the vehicle is deformed by impact.

[0047] As a preferred structure of an embodiment of the present invention, the anti-climbing energy absorption assembly 100 includes an energy absorption tube 120; an anti-climbing tooth 110 connected to one end of the energy absorption tube 120, and an anti-climbing device support 130 connected to the other end of the energy absorption tube 120, and the anti-climbing device support 130 is fixedly connected to the front end of the guardrail.

[0048] The anti-climbing teeth 110 are a structure composed of multiple concave teeth, made of metal material, located at the front end of the anti-climbing energy absorption assembly 100, and can suppress the vertical dislocation movement in a vehicle collision accident. The energy absorption tube 120 is a cylindrical structure with a prefabricated notch. In a collision accident, the energy absorption tube 120 is plastically deformed and the prefabricated notch is broken to absorb the impact energy.

[0049] As a preferred structure of an embodiment of the present invention, a hole is opened at the front end of the guardrail. After the anti-climbing traction rod 210 passes through the hole, it penetrates the anti-climbing device support 130 and the energy absorption tube 120 and is connected to one end of the anti-climbing tooth 110.

[0050] As a preferred structure of the embodiment of the present invention, the anti-climber support 130 is a plate-shaped structure with a boss, and one end of the energy absorbing tube 120 is connected to the boss. The boss structure of the anti-climber support 130 can control the plastic deformation and fracture of the energy absorbing tube 120.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
