Modes for Carrying Out the Invention

[0020] Hereinafter, in order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described with reference to the drawings in the present application. Of course, the embodiments described are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present application.

[0021] In a first form, as shown in FIGS. 1 to 3, an embodiment of the present application provides an intelligent anti-climbing system for a rail vehicle. The intelligent anti-climbing system for a rail vehicle includes a detection module 2, an intelligent anti-climber 3, and a control module 1 that is signal-connected to the detection module 2 and the intelligent anti-climber 3 respectively. Specifically,

[0022] The detection module 2 is used to detect obstacles in real time. The detection module 2 may be attached to the front end of the rail vehicle and used to detect obstacles in front of the rail vehicle. The detection module 2 may be a signal collection sensor or a device for collecting images such as a high-definition camera.

[0023] The intelligent anti-climber 3 includes an anti-climber body 31 and an energy absorption part 32 connected to the anti-climber body 31 and capable of protruding with respect to the anti-climber body 31. The anti-climber body 31 is also an energy absorption module. The energy absorption part 32 is attached to the anti-climber body 31. The energy absorption part 32 protrudes from the anti-climber body 31 along the axial direction of the anti-climber body 31, whereby the total length of the energy absorption structure can be increased, and thus the energy absorption stroke can be increased and the passive safety performance can be improved.

[0024] In the normal state, at least a part of the energy absorption part 32 is hidden inside the anti-climber main body 31, without affecting the appearance of the rail vehicle and without changing the characteristics of the head structure of the rail vehicle.

[0025] The control module 1 is signal-connected to the detection module 2 and the intelligent anti-climber 3 respectively. The control module 1 may be a single-chip microcomputer and is used to control the intelligent anti-climber 3 to perform corresponding operations in response to the detection module 2 detecting an obstacle.

[0026] Here, "controlling the intelligent anti-climber 3 to perform corresponding operations" is understood as follows. When the control module 1 determines that the collision energy between the obstacle train and the present rail vehicle exceeds the energy absorption amount of the anti-climber main body 31 itself, the control module 1 triggers the protrusion of the energy absorption part 32 from the anti-climber main body 31, improves the energy absorption capacity of the intelligent anti-climber 3, spontaneously enhances the energy absorption performance, further increases the allowable collision speed of the rail vehicle, and can protect the personal safety of the driver and passengers and the integrity of the vehicle body structure. When the control module 1 determines that the collision energy between the obstacle train and the present rail vehicle is within the energy absorption amount range of the anti-climber main body 31 itself, it may not send a pop-out signal to the intelligent anti-climber 3. In that case, the intelligent anti-climber 3 does not perform a pop-out operation.

[0027] In one specific embodiment, the anti-climber main body 31 is an energy absorption tube structure. One end of the anti-climber main body 31 is an attachment end, and the other end is an open end. The energy absorption part 32 is inserted into the energy absorption tube structure inside the anti-climber main body 31, and the two are coaxially provided. The anti-climber main body 31 is attached to the vehicle body through the attachment end. The anti-climber main body 31 itself is not movable, and the energy absorption part 32 can protrude to the maximum length with respect to the open end of the anti-climber main body 31.

[0028] According to one embodiment of the present application, in order for the energy absorber to be held in a fixed position after protruding, as shown in FIGS. 2 and 3, the intelligent anti-climber 3 further includes a stopper 33.

[0029] Specifically, the energy absorption part 32 has a first position and a second position with respect to the anti-climber main body 31. In the first position, at least a part of the energy absorption part 32 is located inside the anti-climber main body 31, and the first position is a position where the energy absorption part 32 does not protrude. In the second position, the energy absorption part 32 protrudes from the anti-climber main body 31 and is locked in the second position by the stopper 33, and the second position is a position where the energy absorption part 32 protrudes. By the stopper 33, the position of the energy absorption part 32 can be fixed with respect to the anti-climber main body 31 after protruding, and the purpose of increasing the energy absorption stroke of the intelligent anti-climber 3 can be achieved. The stopper 33 may specifically be a stopper body. The stopper body is attached to the anti-climber main body 31. The number of stopper bodies may be plural. For example, two stopper bodies are provided in a set on both sides in the radial direction of the anti-climber main body 31. As a specific position, it may be provided near the side wall of the open end of the anti-climber main body 31. A groove is opened on the side wall of the open end. One end of the energy absorption part 32 is the tip end, and the other end is the rear end. Stopper grooves corresponding one-to-one to the stopper bodies are provided on the side wall near the rear end of the energy absorption part 32. One end of the stopper body is attached to the anti-climber main body 31 via an elastic body. The other end of the stopper body is inclined downward and pressed against the side wall of the energy absorption part 32. When the energy absorption part 32 protrudes to the maximum length, the stopper body just faces the stopper groove, and the stopper body is engaged in the stopper groove to play the role of a stopper, that is, to limit the position of the energy absorption part 32 and hold the energy absorption part 32 in the second position.

[0030] According to one embodiment of the present application, a trigger mechanism is provided inside the intelligent anti-climber 3. The trigger mechanism is provided at the rear end portion of the anti-climber main body 31 close to the energy absorption portion 32. The trigger mechanism is configured to trigger the ejection of the energy absorption portion 32 from the anti-climber main body 31. By providing power to the energy absorption portion 32 through the trigger mechanism, the energy absorption portion 32 can be pushed out when necessary. Specifically, the trigger mechanism may be a rapid ejection device, or may be a high-pressure air cylinder, a hydraulic cylinder, an air cylinder, or the like.

[0031] According to one embodiment of the present application, the trigger mechanism is electrically connected to the control module 1. Taking the case where the trigger mechanism is a rapid ejection device as an example, an appropriate amount of energy storage material is stored inside the rapid ejection device. When the control module 1 transmits an electrical signal to the rapid ejection device, it triggers the release of the energy of the energy storage material, and the generated impact force pushes and ejects the energy absorption portion 32.

[0032] Specifically, the rapid ejection device 14 includes a storage housing and an energy storage material provided inside the storage housing. The storage housing is fixed and attached to the rear end cover inside the anti-climber main body 31. The shape of the storage housing may be box-shaped, bowl-shaped, or the like, and the specific shape is not limited. The volume of the storage housing is small, the occupied space is small, and it does not occupy the installation space of the energy absorption portion 32. The storage housing may be fixed to the rear end cover inside the anti-climber main body 31 by methods such as adhesion and connection with fastening materials. The specific installation method is not limited, as long as the storage housing can be attached to the rear end cover inside the anti-climber main body 31. After the energy storage material inside the storage housing is triggered, in order to make the generated thrust act on the energy absorption portion 32 as completely as possible, at the first position, the rear end portion of the energy absorption portion 32 is close to or in contact with the storage housing, thereby improving the energy utilization rate.

[0033] Specifically, the amount of the energy storage material placed in the storage housing is determined according to the required thrust. The greater the required thrust, the more energy storage material is placed. Specifically, the energy storage material may be an explosive that can release energy in the presence of an electric spark.

[0034] In this embodiment, the rapid ejection device 14 provides the thrust. Compared with structures such as screws and hydraulics, it has a smaller volume, lighter weight, a relatively small occupied space, and can provide sufficient thrust.

[0035] According to one embodiment of the present application, an emergency brake module 4 is further provided. The emergency brake module 4 is signal-connected to the control module 1. By triggering the emergency brake module 4, an emergency signal is sent to the control module 1, and the control module 1 controls the energy absorption part 32 to eject from the anti-climbing body 31. The emergency brake module 4 is used urgently when the detection module 2 fails. It is used to increase the safety of the operation of the rail vehicle and reduce the damage during a collision.

[0036] According to one embodiment of the present application, in order to make the emergency brake module 4 easy to operate, the emergency brake module 4 is provided in the driver's cab of the rail vehicle. The driver's cab is located at the head of the rail vehicle, has a wide field of view, and can clearly judge whether there is an oncoming rail vehicle in front of the rail vehicle. Therefore, when the emergency brake module 4 is provided in the driver's cab, it can be operated by the driver.

[0037] According to one embodiment of the present application, the emergency brake module 4 is an emergency brake button, and the emergency brake button is provided on the driver's console of the driver's cab to make it easy for the driver to operate.

[0038] In the second form, as shown in FIG. 4, the embodiment of the present application provides a control method for a rail vehicle intelligent anti-climbing system, including the following steps. In S10, the control module 1 receives the obstacle detected by the detection module 2 and recognizes the type of the obstacle by means of an algorithm. Regarding the specific algorithm, this embodiment is not specifically limited, and any algorithm that can realize the recognition of the type of obstacle in the prior art may be used. In S20, when it is recognized that the type of the obstacle is a rail vehicle, the relative speed of the two rail vehicles is further determined. In S30, based on the relative speed of the two rail vehicles, the magnitude of the collision energy of the two rail vehicles is calculated and compared with the energy absorption amount in the retracted state of the intelligent anti-climber 3. In S40, when the collision energy of the two rail vehicles is greater than the energy absorption amount in the retracted state of the intelligent anti-climber 3, a command is sent to the intelligent anti-climber 3 to trigger the ejection of the intelligent anti-climber 3. When the collision energy of the two rail vehicles is within the range of the energy absorption amount in the retracted state of the intelligent anti-climber 3, it is not necessary for the control module 1 to send a command to the intelligent anti-climber 3, and the intelligent anti-climber 3 maintains the retracted state. The control module 1 automatically calculates the relative speed and the magnitude of the energy to be consumed, spontaneously determines whether an ejection operation needs to be performed, improves the energy absorption capacity of the anti-climber, and the recognition speed of the system is fast and the reliability is high.

[0039] According to one embodiment of the present application, S30 further includes calculating the magnitude of the collision energy of the two rail vehicles based on the mass and relative speed of the rail vehicles and comparing it with the energy absorption amount in the retracted state of the intelligent anti-climber 3.

[0040] Taking one specific embodiment as an example, the control method of the rail vehicle intelligent anti-climbing system according to the present application is described. As shown in FIG. 5, it specifically includes the following steps. (1) Monitor the obstacle in front of the rail vehicle in real time. During the normal operation of the rail vehicle, the detector in front of the rail vehicle is in real-time monitoring state, and it determines at any time whether there is an obstacle in front of the route of the rail vehicle. (2) Recognize the type of obstacle and the operating state of the rail vehicle. When the detector detects the presence of an obstacle in front of the rail vehicle, the algorithm recognizes the type of the obstacle in front. When it is a rail vehicle running on the same line, it further determines the relative speed of the two rail vehicles. (3) Determine the magnitude of the collision energy and whether the intelligent anti-climber 3 needs to perform a pop-up operation. Based on the mass and relative running speed of the rail vehicle, the control module 1 calculates the magnitude of the collision energy of the two trains. When the intelligent anti-climber 3 in the retracted state cannot dissipate the collision energy, it sends a command to the intelligent anti-climber 3 to perform a pop-up operation. (4) The anti-climber performs the corresponding operation. After receiving the pop-up command, the rapid pop-up device built in the intelligent anti-climber 3 explodes. Due to the strong impact action of the explosion, the energy absorption part 32 is ejected from the anti-climber body 31. After moving to the corresponding position, the stopper body tilts inward under the action of the spring to limit the position of the energy absorption part 32, thereby increasing the deformation stroke of the intelligent anti-climber 3 and increasing the energy absorption amount.

[0041] In the third form, the embodiment of the present application provides a rail vehicle intelligent anti-climbing system as described above, and the intelligent anti-climber 3 is further provided on a rail vehicle mounted below the front end of the rail vehicle. Without changing the characteristics of the head structure of the rail vehicle, the connection requirements and the curve passing ability requirements, it overcomes the installation of the energy absorption device at the front end of the car body and the limitation of the deformation space, and greatly improves the energy absorption performance of the vehicle.

[0042] Finally, it should be noted that the above embodiments are merely for explaining the technical solutions of the present application and do not limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in each of the above embodiments or equivalently replace some of their technical features. These modifications or replacements do not deviate from the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of each embodiment of the present application.
