Description

Technical Field

[0001] This invention relates to the field of rail vehicle technology, and in particular to an energy-absorbing structure, a car body, and a rail vehicle. Background Technology

[0002] As the operating speed of rail vehicles continues to increase, the requirements for the energy absorption capacity of energy-absorbing structures are becoming higher and higher, and correspondingly, the space required for the arrangement of energy-absorbing structures is also becoming larger and larger.

[0003] To improve aerodynamic performance, the front end of the lead car of a rail vehicle is generally designed with a large elongation-to-slenderness ratio. This shape provides relatively little space for arrangement, and the space also needs to accommodate structures such as obstacle clearers and opening and closing mechanisms. Therefore, the space left for energy-absorbing structures is very limited.

[0004] Therefore, how to balance the energy absorption capacity and space occupation of the energy absorption structure is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides an energy-absorbing structure, which includes a conducting component, a first energy-absorbing device, and a second energy-absorbing device. The conducting component can retract together with the coupler seat. The first energy-absorbing device is fixedly connected to the front of the airtight wall at the front of the vehicle body and is fixedly connected to the coupler seat. The second energy-absorbing device is located behind the airtight wall at the front of the vehicle body and behind the conducting component, so that the conducting component can be cut by the second energy-absorbing device and absorb the collision energy during the retraction process.

[0006] One embodiment of the energy-absorbing structure includes a first guiding device, which includes the conductive component and a guide sleeve. The rear end of the conductive component is inserted into the guide sleeve, and the conductive component cooperates with the guide sleeve to guide the backward movement of the coupler seat.

[0007] In one embodiment of the energy-absorbing structure, the first guide device further includes a fixing plate and a reinforcing rib. The fixing plate is fixedly connected to the outer periphery of the guide sleeve and to the airtight wall at the front end of the vehicle body. The reinforcing rib is fixedly connected between the fixing plate and the outer periphery of the guide sleeve.

[0008] In one embodiment of the energy-absorbing structure, the second energy-absorbing device is fixedly connected to the traction beam of the rail vehicle.

[0009] In one embodiment of the energy-absorbing structure, the conductive component is a tubular structure.

[0010] In one embodiment of the energy-absorbing structure, the second energy-absorbing device includes a cutting tool and a tool mounting base. The tool mounting base has a through hole for the retraction of a conductive component. The cutting tool is mounted on the tool mounting base and extends at least partially into the through hole.

[0011] In one embodiment of the energy-absorbing structure, the second energy-absorbing device includes a connecting sleeve, the tool mounting seat is fixedly connected to the front of the connecting sleeve, and the interior of the connecting sleeve provides retraction space for the conductive component.

[0012] One embodiment of the energy-absorbing structure includes a second guide device, which is slidably connected to the first energy-absorbing device and the coupler seat to guide the first energy-absorbing device and the coupler seat in the backward direction.

[0013] In addition, this application also provides a vehicle body, the vehicle body including a coupler, a coupler seat, an airtight wall connected to the front end of the vehicle body, and an energy-absorbing structure as described in any of the above.

[0014] In addition, this application also provides a rail vehicle, which includes the aforementioned car body.

[0015] The technical effects of the above energy-absorbing structure:

[0016] When the collision energy is transferred to the coupler seat through the coupler and causes the coupler seat to retract, the first energy-absorbing device will be deformed by pressure to absorb the collision energy. At the same time, the transmission component will also retract. During the retraction process, the transmission component will be cut by the second energy-absorbing device to absorb the collision energy. Since the first and second energy-absorbing devices can absorb energy together, they have a large energy absorption capacity.

[0017] Furthermore, the first and second energy-absorbing devices of the aforementioned energy-absorbing structure can be arranged separately, with the second energy-absorbing device positioned behind the airtight wall. This way, the second energy-absorbing device does not occupy the space in front of the airtight wall, thus providing ample space for the obstacle remover and opening / closing mechanism (which are arranged in the space in front of the airtight wall). Therefore, the aforementioned energy-absorbing structure can balance energy absorption capacity and space occupancy.

[0018] In addition, the above-mentioned energy absorption structure can be configured to either have only the first energy absorption device or both the first and second energy absorption devices installed as needed. When only the first energy absorption device is installed, it is only necessary to either not install the second energy absorption device or remove the installed second energy absorption device without making any other modifications. Therefore, it is highly flexible in use. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, the energy-absorbing structure provided in this application includes at least a conductive component 101, a first energy-absorbing device 200, and a second energy-absorbing device 300.

[0027] The transmission component 101 can move backward together with the coupler seat 02.

[0028] The first energy-absorbing device 200 is fixedly connected to the front of the airtight wall 03 at the front of the vehicle body, and the first energy-absorbing device 200 is fixedly connected to the coupler seat 02.

[0029] The second energy-absorbing device 300 is located behind the airtight wall 03 at the front of the vehicle body, and is also located behind the conductive component 101, so that the conductive component 101 can be cut by the second energy-absorbing device 300 and absorb the collision energy during its retraction. The airtight wall 03 is provided with a through hole for the conductive component 101 to pass through during its retraction.

[0030] The energy absorption process of the above-mentioned energy-absorbing structure is as follows: when the collision energy is transmitted to the coupler seat 02 through the coupler 01 and causes the coupler seat 02 to move backward, the first energy-absorbing device 200 will be deformed by pressure to absorb the collision energy. At the same time, the transmission component 101 will also move backward. During the backward movement of the transmission component 101, it will be cut by the second energy-absorbing device 300 to absorb the collision energy.

[0031] The aforementioned energy-absorbing structure has a large energy absorption capacity because the first energy-absorbing device 200 and the second energy-absorbing device 300 can work together to absorb energy. Furthermore, the first energy-absorbing device 200 and the second energy-absorbing device 300 can be arranged separately, with the second energy-absorbing device 300 positioned behind the airtight wall 03. This way, the second energy-absorbing device 300 does not occupy the space in front of the airtight wall 03, thus providing ample space for the obstacle remover and opening / closing mechanism (which are arranged in the space in front of the airtight wall 03). Therefore, the aforementioned energy-absorbing structure can balance energy absorption capacity and space occupancy.

[0032] In addition, the above-mentioned energy absorption structure can be configured to either only install the first energy absorption device 200 or simultaneously install the first energy absorption device 200 and the second energy absorption device 300, depending on the needs. When only the first energy absorption device 200 is installed, it is only necessary to either not install the second energy absorption device 300 or remove the installed second energy absorption device 300, without making any other modifications. Therefore, it is highly flexible in use.

[0033] In one specific embodiment, such as Figure 1 As shown, the front end of the transmission component 101 is fixedly connected to the coupler seat 02, so that it can move backward together with the coupler seat 02. The connection method is not limited and can be bolted or welded.

[0034] In one specific embodiment, the first energy-absorbing device 200 includes a five-hole profile, which has a large energy-absorbing capacity.

[0035] In one specific embodiment, such as Figure 1 As shown, the energy-absorbing structure includes a first guide device 100, which includes the aforementioned conductive component 101 and guide sleeve 102. The rear end of the conductive component 101 is inserted into the guide sleeve 102, and the conductive component 101 and the guide sleeve 102 cooperate to guide the backward movement of the coupler seat 02.

[0036] With this configuration, under the combined guiding action of the transmission component 101 and the guide sleeve 102, the coupler seat 02 moves backward primarily along the longitudinal direction of the rail vehicle (i.e., the front-to-back direction as described herein), and is not prone to lateral movement. This helps improve the energy absorption effect and vehicle safety performance. Moreover, this configuration allows the transmission component 101 to simultaneously perform both guiding and energy absorption functions, making it multi-functional and simplifying the energy absorption structure while reducing its space requirements.

[0037] In one specific embodiment, such as Figure 1As shown, the first guide device 100 further includes a fixing plate 103 and a reinforcing rib 104. The fixing plate 103 is fixedly connected to the outer periphery of the guide sleeve 102, and the connection method is not limited, for example, it can be welded or integrally formed. The fixing plate 103 is also fixedly connected to the airtight wall 03 at the front end of the vehicle body, and the connection method is not limited, for example, it can be bolted or welded. The reinforcing rib 104 is fixedly connected between the fixing plate 103 and the outer periphery of the guide sleeve 102, and the connection method is not limited, for example, it can be welded or integrally formed.

[0038] With this configuration, the guide sleeve 102 is fixedly connected to the airtight wall 03 at the front of the vehicle body via the fixing plate 103, thus achieving the fixed installation of the guide sleeve 102. Furthermore, under the reinforcing effect of the reinforcing rib 104, the guide sleeve 102 can provide reliable support for the transmission component 101.

[0039] In one specific embodiment, the second energy-absorbing device 300 is fixedly connected to the traction beam of the rail vehicle. This configuration allows collision energy to be transferred backwards to the traction beam via the second energy-absorbing device 300, lengthening the collision energy absorption path and thus further enhancing the energy absorption effect.

[0040] In one specific embodiment, such as Figure 1 As shown, the conductive component 101 has a tubular structure, which not only makes it lightweight, but also makes it easy to deform when cut by the second energy absorption device 300, thus achieving a good energy absorption effect.

[0041] In one specific embodiment, such as Figure 1 As shown, the second energy-absorbing device 300 includes a cutting tool 301 and a tool mounting base 302. The tool mounting base 302 has a through hole 302a for the retraction of the conductive component 101. The cutting tool 301 is mounted on the tool mounting base 302, and at least partially extends into the through hole 302a. Thus, when the conductive component 101 retracts through the through hole 302a, it comes into contact with the cutting tool 301 and is cut by it. Specifically, multiple cutting tools 301 can be arranged at intervals around the circumference of the conductive component 101 to ensure the cutting energy absorption effect. Specifically, the tool mounting base 302 can adopt a flange structure.

[0042] In one specific embodiment, such as Figure 1 As shown, the second energy-absorbing device 300 also includes a connecting sleeve 303. The tool mounting base 302 is fixedly connected to the front of the connecting sleeve 303. The connection method is preferably an easy-to-disassemble connection, such as a bolt connection, to facilitate the replacement of the tool mounting base 302 and the cutting tool 301. The connecting sleeve 303 provides sufficient space for the transmission component 101 to retract. Additionally, the connecting sleeve 303 can be fixedly connected to the traction beam of a rail vehicle.

[0043] In one specific embodiment, such as Figure 1 As shown, the energy-absorbing structure includes a second guide device 400, which is slidably connected to the first energy-absorbing device 200 and the coupler seat 02 to guide the backward movement of the first energy-absorbing device 200 and the coupler seat 02. With this configuration, under the guidance of the second guide device 400, the coupler seat 02 moves backward primarily along the longitudinal direction of the rail vehicle, and is less prone to lateral movement. The first energy-absorbing device 200 deforms primarily along the longitudinal direction of the rail vehicle, and is less prone to lateral deformation. This improves the energy absorption effect and vehicle safety performance.

[0044] The above specific embodiments can be freely combined without conflict.

[0045] In addition, this application also provides a vehicle body, which includes a coupler, a coupler seat, an airtight wall connected to the front end of the vehicle body, and the aforementioned energy-absorbing structure.

[0046] In addition, this application also provides a rail vehicle, which includes the aforementioned car body.

[0047] The above examples illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
