Description

Technical Field

[0001] This invention relates to the field of anti-climb energy absorption devices, and more specifically, to a train anti-climb energy absorption device with a deformable capsule filled with aluminum foam. Background Technology

[0002] When the front of one train collides with the rear of the train in front, if the connection point is not strong enough and breaks or fails, the following train may wedge itself under or above the preceding train. This causes the train's structure to overlap and penetrate each other like a retractable telescope. The enormous impact energy generated will be transmitted directly to the passengers and the train almost without loss through the train's structure, leading to catastrophic consequences. This is where anti-climb energy absorption devices come in. This structure can effectively prevent trains from climbing each other and can greatly reduce the impact of the collision, preventing it from acting directly on the train body.

[0003] Most existing anti-climb energy absorption devices use honeycomb energy absorbers as the main buffer structure. However, the traditional continuous honeycomb structure forms a wavefront contact area during collision, and the stress wave propagation and reflection cause load fluctuations. The utilization rate of energy absorption elements is low, and the buffering effect of a simple honeycomb energy absorber is limited, which cannot bring sufficient sense of security. To solve these problems, this application proposes a novel train anti-climb energy absorption device with deformable capsules filled with aluminum foam. Summary of the Invention

[0004] The purpose of this invention is to provide a train anti-climb energy absorption device with a deformable capsule filled with aluminum foam, in order to solve the problem mentioned in the background art: when an impact occurs, multiple structures are used to mitigate the impact force generated by the collision.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A train anti-climb energy absorption device with deformable capsules filled with aluminum foam includes:

[0007] An anti-climb mechanism includes a housing, an inner rear plate, a first pressure sensor on the end face of the rear plate, a hexagonal alloy buffer assembly connected to the end face of the rear plate, an anti-climb plate connected to the end face of the hexagonal alloy buffer assembly, four anti-climb teeth on the end face of the anti-climb plate, and porous aluminum foam inside the hexagonal alloy buffer assembly.

[0008] The buffer mechanism includes a rear shell and two elastic bladders. The inner wall of the rear shell is provided with two side shells. Each of the two side shells is provided with a clamping shell. The interior of the rear shell is provided with a push plate. The end faces of the two elastic bladders are connected with contact plates.

[0009] It also includes two movable plates, four locking blocks and a gear cylinder. The interior of the rear shell is provided with two triangular blocks. The end faces of the two triangular blocks are connected to alloy cutting heads. The end faces of the two triangular blocks are connected to push blocks. The end faces of the two movable plates are connected to drive plates. The end face of the push plate is connected to a cutting block.

[0010] By adopting the above technical solution, the impact force is effectively reduced by combining hexagonal alloy buffer groups and porous aluminum foam.

[0011] By using the sliding fit between the clamping shell and the contact plate, the friction force of the push plate movement is increased, thereby reducing the impact force.

[0012] By using an alloy cutting tip to cut the cutting block, kinetic energy is converted into other forms of energy, effectively increasing its buffering capacity.

[0013] Preferably, the outer shell has an inner shell inside, the inner shell is connected to the anti-climb plate, and the hexagonal alloy buffer group is disposed inside the inner shell.

[0014] By adopting the above technical solution, the impact force brought by the anti-climb plate is buffered by the hexagonal alloy buffer group, so as to avoid the impact being too large and directly acting on the train.

[0015] Preferably, the end face of the rear plate is provided with four outer rods, and all four outer rods are disposed inside the inner shell.

[0016] By adopting the above technical solution, the stability of the rear plate inside the outer shell is increased by the outer rod, allowing the inner shell to slide more stably.

[0017] Preferably, the end face of the push plate is provided with four inner rods, all four inner rods are connected to the anti-climb plate, and the four inner rods are respectively disposed inside the four outer rods.

[0018] By adopting the above technical solution, the anti-climbing plate will push the push plate through the inner rod when it moves, and the inner rod that slides inside the outer rod will be more stable.

[0019] Preferably, the push plate has two notches on its end face, the two side shells are respectively disposed inside the two notches, the two notches are each provided with a placement groove, the two elastic bladders are respectively disposed inside the two placement grooves, and the end faces of the two contact plates are each provided with three holes.

[0020] By adopting the above technical solution, the elastic bladder is filled with a high-friction liquid, which can flow onto the clamping shell through the leakage holes on the contact plate, effectively increasing the friction between the contact plate and the clamping shell.

[0021] Preferably, a strong spring is provided between the two clamping shells and the two side shells, and the two contact plates are respectively connected to the two clamping shells.

[0022] By adopting the above technical solution, a strong spring pushes the clamping shell, causing the clamping shell to continuously squeeze the push plate, thereby increasing the friction force for the push plate to move.

[0023] Preferably, each of the two triangular blocks has a slot on its end face, and each of the two slots has two inner slots. The four locking blocks are respectively disposed inside the four inner slots. A locking spring is disposed between each of the four inner slots and the four locking blocks. A second pressure sensor is connected to each of the end faces of the two drive plates, and multiple locking slots are disposed on each of the end faces of the two drive plates.

[0024] By adopting the above technical solution, when the drive plate is squeezed by the cutting block, the second pressure sensor above it will detect the pressure and thus determine the impact force again. Moreover, the cutting block will squeeze the drive plate into the cavity, allowing the card block to be stuck in different card slots, thereby fixing the position of the moving plate and realizing the adjustment of the position of the push block.

[0025] Preferably, the rear shell has two placement shells inside, each with an upper groove on its end face, and two pushing blocks are respectively disposed inside the two upper grooves, each with multiple upper teeth on its end face.

[0026] By adopting the above technical solution, the pusher block moves inside the upper groove of the housing, allowing the pusher block to stably push the triangular block.

[0027] Preferably, both of the two placement shells have a lower groove on their end faces, and the two movable plates are respectively disposed inside the two lower grooves. The end faces of the two movable plates are provided with multiple lower teeth.

[0028] By adopting the above technical solution, the moving plate moves inside the lower groove. The inward movement of the moving plate can drive the pushing block to move outward, thereby realizing the feeding of the triangular block.

[0029] Preferably, a rotating groove is provided between the two upper grooves and the two lower grooves, and the two toothed cylinders are respectively disposed inside the two rotating grooves. The two toothed cylinders are respectively meshed with multiple upper teeth and multiple lower teeth.

[0030] By adopting the above technical solution, when the moving plate moves, the lower tooth will drive the toothed cylinder to rotate, and this rotation will drive the push block to move in the opposite direction through the upper tooth, thereby realizing the movement of the triangular block.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1) When this anti-climb energy absorption device is in use, the outer shell of the anti-climb mechanism is equipped with a hexagonal alloy buffer group, and the hexagonal alloy buffer group is filled with porous aluminum foam. When the anti-climb plate is impacted, the impact will act on the hexagonal alloy buffer group, causing the hexagonal alloy buffer group to fold along the creases set inside. The impact force is effectively offset by the porous aluminum foam inside, avoiding direct impact on the train. The impact force can be monitored in real time by the first pressure sensor.

[0033] 2) When this anti-climb energy-absorbing device is in use, a side shell is provided inside the rear shell of the buffer mechanism, and a clamping shell is provided inside the side shell. The clamping shell and the contact plate on the push plate are fitted together. The elastic bladder squeezes out the high-friction liquid inside it from the contact plate to the end face of the clamping shell through its own squeezing force, thereby increasing the sliding friction between the contact plate and the clamping shell, making the push plate more difficult to push, and making the buffer mechanism more effective.

[0034] 3) When this anti-climb energy-absorbing device is in use, a triangular block is installed in the rear shell of the buffer mechanism. An alloy cutter head is connected to the end face of the triangular block. When the push plate drives the cutting block to move backward, the alloy cutter head will cut the end face of the cutting block, converting kinetic energy into the energy required to cut metal and the heat energy to generate metal chips. This effectively alleviates the impact brought by the push plate. Moreover, the downward pressing cutting block will squeeze the drive plate. Through the transmission of multiple structures, the moving plate drives the push plate to move outward, thereby enabling the triangular block to perform a feeding action, which facilitates timely contact with the surface of the cutting block.

Detailed Implementation

[0047] Example 1, please refer to Figures 1 to 4 The anti-climb mechanism 1 includes a housing 101, a rear plate 102 inside the housing 101, a first pressure sensor 103 on the end face of the rear plate 102, a hexagonal alloy buffer assembly 104 connected to the end face of the rear plate 102, an anti-climb plate 106 connected to the end face of the hexagonal alloy buffer assembly 104, four anti-climb teeth 107 on the end face of the anti-climb plate 106, and porous aluminum foam 109 inside the hexagonal alloy buffer assembly 104. The hexagonal alloy buffer assembly 104 and the porous aluminum foam 109 work together to effectively reduce the impact force.

[0048] Specifically, the outer shell 101 has an inner shell 105 inside, the inner shell 105 is connected to the anti-climb plate 106, the hexagonal alloy buffer group 104 is set inside the inner shell 105, and the end face of the rear plate 102 is provided with four outer rods 108, all of which are set inside the inner shell 105.

[0049] Furthermore, the rear plate 102 is fixedly mounted on the inner rear wall of the outer casing 101, the first pressure sensor 103 is embedded in the front end face of the rear plate 102, and the hexagonal alloy buffer assembly 104 is bolted between the anti-climb plate 106 and the rear plate 102. This hexagonal alloy buffer assembly 104 is welded from regular hexagonal aluminum-magnesium alloy cells and can be freely configured in different numbers, with a wall thickness of 1.5-3mm. The anti-climb plate 106 is located at the front end of the outer casing 101, and four anti-climb teeth 107 are equidistantly fixed on the front end face of the anti-climb plate 106. 07 is set at a 55-degree angle. Porous aluminum foam 109 is fixedly installed inside each hexagonal alloy of the hexagonal alloy buffer group 104. The porosity of the core of the porous aluminum foam 109 is 85% → 70% of the surface. The inner shell 105 is slidably sleeved on the inner wall of the outer shell 101. The inner shell 105 is fixedly installed on the rear end face of the anti-climb plate 106. The front part of the hexagonal alloy buffer group 104 is set inside the inner shell 105. The outer rods 108 are threadedly installed at the four corners of the front end face of the rear plate 102. The four outer rods 108 are slidably embedded in the four corners of the inner shell 105.

[0050] The steps of using this invention are as follows: When trains collide with each other, the anti-climb plate 106 will come into contact with another anti-climb plate 106, and the anti-climb teeth 107 will mesh with each other to prevent the train from moving upward. Moreover, the impact force acting on the anti-climb plate 106 will drive the inner shell 105 to move into the outer shell 101, thereby squeezing the hexagonal alloy buffer group 104 inside the outer shell 101. This causes the hexagonal alloy buffer group 104 to fold along the creases set inside it. When the hexagonal alloy folds, it will squeeze the porous aluminum foam 109 inside, causing it to deform and absorb the energy brought by the impact. The squeezing force on the hexagonal alloy group will press on the first pressure sensor 103, thereby monitoring the magnitude of the impact force and facilitating subsequent accurate judgment.

[0051] Example 2, please refer to Figure 1 , Figures 4 to 7 The difference from embodiment 1 is that the buffer mechanism 2 includes a rear shell 209 and two elastic bladders 207. The inner wall of the rear shell 209 is provided with two side shells 210, and each of the two side shells 210 is provided with a clamping shell 211. The rear shell 209 is provided with a push plate 201. The end faces of the two elastic bladders 207 are connected to contact plates 204. Through the sliding cooperation between the clamping shells 211 and the contact plates 204, the friction of the push plate 201 is increased, thereby reducing the impact force.

[0052] Specifically, the end face of the push plate 201 is provided with four inner rods 202, all of which are connected to the anti-climb plate 106. The four inner rods 202 are respectively located inside the four outer rods 108. The end face of the push plate 201 is provided with two notches 203. The two side shells 210 are respectively located inside the two notches 203. The two notches 203 are each provided with a placement groove 206. The two elastic bladders 207 are respectively located inside the two placement grooves 206. The end faces of the two contact plates 204 are each provided with three drainage holes 205. A strong spring 212 is provided between the two clamping shells 211 and the two side shells 210. The two contact plates 204 are respectively connected to the two clamping shells 211.

[0053] Furthermore, the rear shell 209 is fixedly mounted on the rear end face of the outer shell 101, and two side shells 210 are symmetrically fixedly mounted on the front side of the inner walls on both sides of the rear shell 209. The clamping shell 211 is slidably mounted on the inner wall of the side shell 210, and the push plate 201 is slidably mounted on the inner wall of the rear shell 209. Four inner rods 202 are fixedly mounted at the four corners of the front end face of the push plate 201 and at the four corners of the rear end face of the anti-climb plate 106. The four inner rods 202 are slidably sleeved inside the four outer rods 108, and the four inner rods 202 penetrate the inner shell 105. Two notches 203 are formed in the... At the middle position of the two end faces of the push plate 201, two placement grooves 206 are opened on the inner wall of the opposite side of the two notches 203. Two elastic bladders 207 are fixedly installed inside the two placement grooves 206. The elastic bladders 207 have sufficient elasticity to squeeze out the high-friction liquid inside them, and they also have a certain supporting force. Two contact plates 204 are respectively fixedly installed on the opposite end faces of the two elastic bladders 207. Three leakage holes 205 are opened at the middle position of the end face of the contact plate 204. The strong springs 212 are in groups of three and are respectively fixedly installed between the two clamping shells 211 and the two side shells 210.

[0054] The steps of using this invention are as follows: High-friction liquid is injected into the elastic bladder 207 through the drain hole 205. The push plate 201 is placed inside the rear shell 209, and the side shell 210 enters the notch 203. At this time, the elastic bladder 207 pushes the contact plate 204 and the clamping shell 211 to make contact. The high-friction liquid is slowly squeezed out from the drain hole 205 through the elastic bladder 207 to the surface of the clamping shell 211. The clamping shell 211 is pushed tightly against the inside of the notch 203 by the strong spring 212 inside the side shell 210. When the push plate 201 is pushed, the plate will move into the rear shell 209. At this time, the contact plate 204 will rub against the clamping shell 211. Moreover, the friction is strengthened by the action of the high-friction liquid, making it more difficult for the push plate 201 to move backward, thereby increasing the buffering effect.

[0055] Example 3, please refer to Figure 1 , Figures 4 to 11The difference from embodiment 2 is that it also includes two movable plates 220, four locking blocks 227 and a gear cylinder 222. The interior of the rear shell 209 is provided with two triangular blocks 215. The end faces of the two triangular blocks 215 are connected to alloy cutter heads 216 and push blocks 218. The end faces of the two movable plates 220 are connected to drive plates 223. The end face of the push plate 201 is connected to a cutting block 213. The alloy cutter heads 216 cut the cutting blocks 213, converting kinetic energy into other forms of energy and effectively increasing its buffering capacity.

[0056] Specifically, each of the two triangular blocks 215 has a slot 226 on its end face, and each of the two slots 226 has two inner grooves 230 inside. Four locking blocks 227 are respectively disposed inside the four inner grooves 230. A locking spring 208 is disposed between each of the four inner grooves 230 and the four locking blocks 227. Each of the two drive plates 223 has a second pressure sensor 224 connected to its end face, and each of the two drive plates 223 has multiple locking slots 225 on its end face. The rear shell 209 has two placement shells 214 inside, and each of the two placement shells 214 has an upper groove 217 on its end face. Each push block 218 is disposed inside the two upper slots 217. Each end face of the two push blocks 218 is provided with multiple upper teeth 228. Each end face of the two placement shells 214 is provided with a lower slot 219. Each moving plate 220 is disposed inside the two lower slots 219. Each end face of the two moving plates 220 is provided with multiple lower teeth 229. Each upper slot 217 and the two lower slots 219 is provided with a rotating groove 221. Each toothed cylinder 222 is disposed inside the two rotating grooves 221. Each toothed cylinder 222 is meshed with multiple upper teeth 228 and multiple lower teeth 229 respectively.

[0057] Furthermore, both triangular blocks 215 are slidably disposed on the rear inner wall of the rear shell 209, and the alloy cutter head 216 is fixedly disposed on the front end face of the triangular blocks 215 by bolts. Two placement shells 214 are respectively fixedly disposed on both sides of the rear inner wall of the rear shell 209. Two upper grooves 217 are respectively opened on the front side of the opposite end face of the two placement shells 214, and two lower grooves 219 are respectively opened on the rear side of the opposite end face of the two placement shells 214. Two pushing blocks 218 are slidably disposed inside the two upper grooves 217, and two moving plates 220 are respectively disposed on the rear side of the opposite end face of the two placement shells 214. The two lower slots 219 are not slidably disposed inside the two lower slots 219. Two empty slots 226 are respectively opened on the rear side of the opposite end faces of the two triangular blocks 215. Two drive plates 223 are respectively fixedly disposed on the opposite end faces of the two moving plates 220 and slidably disposed inside the empty slots 226. The cutting block 213 is fixedly disposed on the rear end face of the push plate 201. Two rotating slots 221 are respectively opened on the adjacent side between the two upper slots 217 and the two lower slots 219. Two toothed cylinders 222 are respectively rotatably disposed between the upper and lower inner walls of the two rotating slots 221. Two push plates 223 are respectively rotatably disposed between the upper and lower inner walls of the two rotating slots 221. The rear end face of block 218 is provided with multiple upper teeth 228, and the front end face of the two moving plates 220 is provided with lower teeth 229. Four inner grooves 230 are respectively opened on opposite sides of the upper and lower inner walls of the two empty grooves 226. A locking block 227 is slidably disposed inside the inner groove 230. A locking spring 208 is fixedly disposed between the locking block 227 and the inner groove 230. Multiple locking slots 225 are respectively fixedly disposed on the upper and lower end faces of the drive plate 223. The locking block 227 is locked inside the locking slot 225. The locking block 227 is close to the moving plate 220. One end face has a small arc setting, while the other end face has a large arc setting. The second pressure sensor 224 is embedded in the arc of the front end face of the drive plate 223. The adjacent end faces of the two drive plates 223 are composed of arc-shaped blocks of the same length as a slot 226. This arc-shaped block can change the longitudinal extrusion force of the cutting block 213 into a lateral extrusion force to both sides, so that the moving plate 220 can move into the lower slot 219. The tilt angle of the triangular block 215 is the same as the tilt angle of the cutting block 213, so that the alloy cutter head 216 can fit against the surface of the cutting block 213.

[0058] The steps of using this invention are as follows: When the push plate 201 drives the cutting block 213 to move backward, the cutting block 213 will first contact the alloy cutter head 216. The alloy cutter head 216 will cut the inclined surface of the cutting block 213. As the cutting block 213 continues to move backward, it will press against the arc surface of the drive plate 223, causing the drive plate 223 to move into the cavity 226. At this time, the locking block 227 will be pressed into the inner groove 230 through the large arc surface, so that the locking spring 208 is in an energy storage state. The position of the locking block 227 is parallel to... The plate is not fully inserted into the new snap-fit ​​groove 225, but rather rests on the edge of the snap-fit ​​groove 225 with a small arc surface. This stabilizes the position of the drive plate 223, and the moving drive plate 223 pushes the moving plate 220. The moving plate 220, moving into the lower groove 219, drives the gear cylinder 222 to rotate via the upper tooth 228. The gear cylinder 222, via the upper tooth 228, drives the push block 218 to move outward from inside the upper groove 217, allowing the triangular plate to re-adhere to the cutting block 213. At this time, the triangular block 215 is cut... The blocking push block 218 of the cutting block 213 can no longer move even half an inch, causing the gear cylinder 222 and the moving plate 220 to also be unable to change, thus determining the moving distance of the drive plate 223. When the push plate 201 is pulled by the front anti-climb mechanism 1 and resets, the cutting block 213 will also reset and will not continuously squeeze the drive plate 223, allowing the triangular block 215 to move. At this time, the locking spring 208 inside the inner groove 230 will not be subjected to an unstoppable force when pushing the locking block 227. The locking block 227 will squeeze through the small arc set on its surface. The edge of the locking groove 225 allows the locking block 227 to be squeezed into the locking groove 225 on the drive plate 223 near the second pressure sensor 224, causing the drive plate 223 to move to one side again. This drives the push block 218 to move the triangular block 215 again, so that the alloy cutter head 216 is in a position slightly deeper than it is in contact with the cutting block 213. This allows the alloy cutter head 216 to cut the cutting block 213 in the next operation. Moreover, the impact can be detected again by the second pressure sensor 224 on the drive plate 223.

[0059] The steps of using this invention are as follows: When trains collide with each other, the anti-climb device will make contact first, and the anti-climb teeth 107 on the anti-climb plate 106 will mesh with each other to prevent one train from climbing over another. The impact force generated by the collision will squeeze the anti-climb plate 106, causing it to squeeze the hexagonal alloy buffer group 104 inside the outer shell 101, causing it to fold and squeeze the porous aluminum foam 109 inside. The impact force generated at this time can be detected by the first pressure sensor 103 on the rear plate 102. The anti-climb plate 106 will push the push plate 201 through the inner rod 202 to generate a pushing force, causing the push plate 201 to move into the rear shell 209. When the push plate 201 moves, the elastic bladder 207 will continuously apply the high friction fluid contained inside it through the holes to the clamping shell 211. The clamping shell 211 passes through the inside of the side shell 210. The powerful spring 212 fits tightly inside the notch 203, causing the push plate 201 to be subjected to strong friction from the notch 203, contact plate 204 and clamping shell 211 when it moves, increasing the difficulty of its backward movement. The continuously backward-moving push plate 201 will bring the cutting block 213 to the position of the triangular block 215, where it will be cut by the alloy cutter head 216 in front of the triangular block 215. The cutting block 213 will press against the drive plate 223, causing the drive plate 223 to press against the moving plate 220. The moving plate 220 drives the gear cylinder 222 to rotate inside the rotating groove 221 through the lower tooth 229. The gear cylinder 222 drives the push block 218 to push the triangular block 215 through the upper tooth 228, causing the triangular block 215 to produce a feeding action. The drive plate 223 engages the locking block 227 pushed by the spring 208 and engages it inside the locking groove 225 for fixation.
