Description

  The present invention relates to an impact absorbing device and a vehicle that alleviate impact energy caused by collision between mutually connected vehicles.

  When a rear-end collision between trains or a collision between a train and an obstacle occurs, an impact compression force is generated between the following vehicles forming the train. A shock absorber is provided at the rear of the coupler as a device that absorbs an impact when the vehicles are connected to each other and compression and tension between the vehicles that occur during acceleration and deceleration of the train. However, when the impact is large, the shock cannot be absorbed by the shock absorber, and the shock absorber is damaged. And a coupler also breaks, vehicle edge parts collide, and a vehicle body is damaged. As an apparatus for mitigating such collision between vehicles, for example, FIGS. 4 and 5 of Patent Document 1 disclose a shock absorber for preventing direct hit between vehicles. In this shock absorber, an oil bag is arranged at the upper end portion and the side end portion of the end face of the vehicle, and the impact between the vehicles is mitigated by the oil bag.

JP 2008-120383 A

  However, a fall prevention device (outer holo) that prevents passengers from falling from the platform into the gap between the vehicles is attached to the side end of the end face of the vehicle. For this reason, it is required to clarify the positional relationship between the shock absorber and the fall prevention device on the end face of the vehicle. However, Patent Document 1 does not specify the positional relationship between the shock absorber and the fall prevention device.

  Accordingly, an object of the present invention is to prevent a passenger from falling into a gap between vehicles and an impact buffering function that alleviates an impact caused by a collision between vehicle end portions in the same composition without securing a new installation space. An object of the present invention is to provide an impact absorbing device having a fall prevention function and a vehicle using the same.

The impact absorbing device of the present invention is an impact absorbing device that relieves an impact at the time of a collision between mutually connected vehicles and prevents a passenger from falling from a platform to a gap between the vehicles. It is arranged between mutually connected vehicles, and is attached to the side end of the end face of the vehicle, and has an impact absorber that absorbs impact energy at the time of collision by plastic deformation The shock absorber attached to the side end of the face of one of the two vehicles connected to each other extends toward the face of the other facing vehicle. Moreover, it is preferable that the said shock absorber is attached inside the side edge part and side edge part of the end face of a vehicle.

  According to the present invention, when an impact compressive force is generated between the vehicles, the impact absorber absorbs the impact by colliding with the opposite wife surface and plastically deforming. Thereby, even if a large impact compression force is generated between the vehicles, damage to the vehicle end (vehicle body) can be reduced. Moreover, the clearance gap produced between vehicles is closed by the impact-absorbing device of the present invention. Thereby, it can prevent that a passenger falls from the platform to the clearance gap between vehicles. Thus, the device according to the present invention has both an impact buffering function and a fall prevention function. Furthermore, since the impact absorbing device of the present invention is attached to the space for attaching the fall preventing device, it is not necessary to secure a new installation space for attaching the impact absorbing device.

Further, the impact absorbing device of the present invention, that further comprise an elastic member which extends toward the wife surface of the other vehicle on the tip of the impact absorbing member as described above. Since there is a curved line on the train route, the shock absorbers attached to the opposite wife surfaces do not contact each other and the shock absorber does not contact the opposite wife surface while traveling on the curved route Thus, the shock absorber is formed. Depending on the route conditions, the length of the shock absorber in the longitudinal direction is shortened, and the shock absorber alone cannot sufficiently close the gap between the vehicles, but the elastic body provided at the tip of the shock absorber absorbs the space between the vehicles. The gap can be closed. Thus, even if the shape of the shock absorber is changed according to the travel route of the train, the shock absorber of the present invention sufficiently exhibits the shock buffering function and the fall prevention function.

  Further, in the shock absorbing device of the present invention, the shock absorber attached to the side end portion of the wife face of one of the two connected vehicles, and the side edge of the opposite face of the other vehicle. It is preferable that the shock absorber attached to the part is disposed so as to be shifted from each other in the vertical direction. According to this, there is a curved route on the train route, and even if the opposite wife surfaces approach while the train is running, the shock absorbers attached to each of the opposite wife surfaces may contact each other. Absent. For this reason, it is not necessary to change the shape of the shock absorber according to the travel route of the train (for example, it is not necessary to adjust the length in the longitudinal direction from the mounting portion of the shock absorber to the vehicle to the tip portion). ). Thus, with a simple configuration, it is possible to sufficiently absorb an impact between the connected vehicles and to close a gap between the connected vehicles.

  In the shock absorber of the present invention, it is preferable that the shock absorber is made of a metal material. According to this, a shock can be more fully absorbed by the metal shock absorber. In addition, the apparatus has a simple structure and excellent maintenance.

  Moreover, it is preferable that the some vehicle connected of this invention is equipped with the above-mentioned impact-absorbing apparatus arrange | positioned between the vehicles connected mutually. According to this, the impact absorbing device can absorb the impact caused by the collision between the vehicle end portions in the same knitting, so that damage to the vehicle body can be reduced. Moreover, since the gap between the mutually connected vehicles is closed by the impact absorbing device, it is possible to prevent the passenger from falling from the platform to the gap between the vehicles. Furthermore, since it is not necessary to secure a new installation space for attaching the shock absorbing device, the shock absorbing device can be attached to an existing vehicle, and the shock absorbing function and the fall preventing function are exhibited with a simple configuration.

  Moreover, in the above-mentioned vehicle, it is preferable that the strength of the shock absorber is lower than the strength of the end face of the vehicle facing the shock absorber. According to this, even when the impact absorber or the impact absorber to which the elastic body is extended collides with the opposite wife surface, the impact absorber surely plastically deforms and absorbs the impact energy.

  According to the impact absorbing device and the vehicle of the present invention, the impact due to the collision between the vehicle end portions in the same knitting can be absorbed and reduced by the impact absorbing body, so that damage to the vehicle body can be reduced. Moreover, since the shock absorbing device is provided between the mutually connected vehicles, a gap generated between the vehicles can be closed. For this reason, this invention exhibits the fall prevention function to the clearance gap between vehicles with an impact buffering function. Furthermore, since the shock absorbing device is installed in the space for attaching the fall prevention device, it is not necessary to secure a new installation space in the vehicle.

It is a front view of the end face of the vehicle by other modification of the present invention, (a) shows one end face which opposes, and (b) shows the other end face which faces.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<First embodiment>
Here, a first embodiment of a vehicle and an impact absorbing device according to the present invention will be described with reference to FIGS. FIG. 2 shows the two opposite face surfaces shown in FIG. 1 and 2 mainly show the positions where the shock absorbers are attached, and the description of the members excluding the shock absorbers is omitted.

  As shown in FIG. 1, the vehicle 1 is formed from a plurality of vehicles 10. The vehicles 10 are connected to each other by a connector 3. A shock absorber 4 is disposed behind the coupler 3. There is a gap 5 between the opposing wife surfaces 30. An impact absorbing device 100 is disposed in the gap 5. Further, the holo 6 is stretched between the facing wife surfaces 30.

[Shock absorber 100]
The shock absorber 100 has a plurality of rod-shaped shock absorbers 21. The shock absorber 21 is attached to both end portions of the end face 30 of the vehicle 10 so that the longitudinal direction of the impact absorber is perpendicular to the end face 30. In addition, although the outer holo for fall prevention is normally attached to the both ends of the end face 30, in this embodiment, the shock absorber 21 is attached in place of the outer holo.

  The position where the shock absorber 21 is attached to the end face 30 will be described in detail. In one (left side) of the opposite face surfaces 30 in FIG. 1 (FIG. 2A), on both left and right end portions, from the position slightly above the center with respect to the height direction, downward, etc. Three shock absorbers 21 are attached to both the left and right sides at a distance from each other. Further, the other (right) wife face 30 (FIG. 2 (b)) of the opposite wife faces 30 is separated at equal intervals from the vicinity of the center in the height direction to the lower edge at both left and right ends. Three bodies 21 are attached to each of the left and right sides. Here, the equal intervals in FIGS. 2A and 2B are the same intervals, and are the intervals obtained by equally dividing the lower end portion from the center in the height direction of the vehicle 10 into a plurality of equal intervals. Thus, since the shock absorber 21 is not attached at the same position of the two opposite face surfaces 30, the face face 30 shown in FIG. 2 (a) and the face face 30 shown in FIG. 2 (b) face each other. If it does, the impact-absorbing body 21 attached to each wife face 30 which opposes will not mutually oppose, but will mutually shift | deviate up and down (FIG. 1). In addition, the position and number which attach the impact-absorbing body 21 are not restricted to the position shown to Fig.2 (a) based on this embodiment, (b).

[Shock absorber 21]
The shock absorber 21 has a rod-like hollow member 21a, a flat plate 21b that covers the front end of the hollow member, and a flat plate 21c that covers the rear end. The hollow member 21a and the flat plates 21b and 21c are made of an aluminum alloy. The aluminum alloy has a strength lower than the strength of the vehicle body (including the end face) of the vehicle 10. The cross section of the hollow member 21a is formed in a Japanese character shape with a partition formed at the center. The flat plate 21b that covers the tip of the hollow member 21a has a plane that is substantially the same shape as the cross section of the hollow member 21a, and the flat plate 21c that covers the rear end of the hollow member 21 has a plane that is slightly larger than the cross section of the hollow member 21a. ing. Each of the flat plates 21b and 21c is welded to each of the front end and the rear end of the hollow member 21a.

  When attaching the shock absorber 21 to the side end portion of the end face 30, the flat plate 21c, which is the rear end of the impact absorber 21, is fixed to the end face 30 using a bolt or the like. At this time, the shock absorber 21 is disposed such that the cross section of the hollow member 21a is a Japanese character. As shown in FIG. 1, the shock absorber 21 attached to the end face 30 has the longitudinal direction of the impact absorber 21 perpendicular to the end face 30 and is attached to the end face 30 (after the impact absorber 21). It extends in the longitudinal direction of the vehicle 10 from the end) toward the facing wife surface 30. The shock absorber 21 according to the present embodiment is formed to a length that is located near the center between the wife surfaces 30 with which the tip of the shock absorber 21 is opposed.

  When an impact compression force is generated between the connected vehicles 10, the facing wife face 30 comes close to the front end (flat plate 21 b) of the shock absorber 21 and collides with the facing wife face 30. The impact absorber 21 (hollow member 21a) having a lower strength than the vehicle body (wife surface 30) is plastically deformed and absorbs impact energy at the time of collision.

  In this embodiment, an aluminum alloy is used for the shock absorber 21, but a light alloy other than an aluminum alloy, a steel material, foamed aluminum, or the like may be used. The material used for the shock absorber 21 is preferably a material having a strength lower than that of the vehicle body of the vehicle 10. Further, the shape of the shock absorber 21 is not limited to the rod shape used in the present embodiment.

[Connector 3]
The coupler 3 is provided at the floor lower end portion of the vehicle 10. A connector 3 provided at the rear end of the preceding vehicle and a connector 3 provided at the front end of the following vehicle are connected, whereby the two vehicles 10 are connected to each other.

[Buffer 4]
A shock absorber 4 is provided behind the coupler 3. The shock absorber 4 absorbs an impact force such as a compressive force or a tensile force that is generated between the vehicles, and alleviates the impact.

[Holo 6]
The holo 6 is a through hood that forms a passage between the connected vehicles 10 and includes a holo cloth and a holo bone (not shown) that holds the holo cloth in a bellows shape. The holo 6 is spanned from the hollow seat 20 provided on one of the opposing wife surfaces 30 to the hollow seat 20 provided on the other wife surface 30.

  As described above, according to the vehicle 1 and the impact absorbing device 100 of the present embodiment, the following effects are obtained. In a vehicle that does not include the shock absorbing device 100, if a large compressive shock force is generated between the mutually connected vehicles, the shock force cannot be reduced only by the buffer capacity of the shock absorber 4, and the shock absorber 4 and The coupler 3 is damaged. And the vehicle edge parts which oppose collide, and a vehicle body is damaged. However, in the vehicle 1 according to the present embodiment, when a large compressive impact force is generated between the mutually connected vehicles 10, the shock absorber 21 attached to the side end of the wife surface 30 faces the wife surface 30 ( It collides with the car edge) and plastically deforms to absorb the impact energy. As a result, it is possible to prevent damage to the facing wife face 30 (vehicle end). Further, the gap 5 generated between the two vehicles 10 is closed by the plurality of shock absorbers 21 attached to the end face 30. Thereby, it is possible to prevent the passenger from falling from the platform to the gap 5. Thus, the impact absorbing device 100 and the vehicle 1 of the present invention exhibit an impact buffering function and a fall prevention function. Furthermore, since the shock absorber 21 is attached to the side end portion of the end face 30 to which the outer holo is attached, it is not necessary to secure a new installation space for the apparatus.

  Of the two vehicles 10 connected to each other, the shock absorber 21 attached to the side end of the end face 30 of one vehicle 10 and the side end of the end face 30 of the other vehicle 10 facing each other. The shock absorber 21 attached to the part is disposed so as to be shifted from each other in the vertical direction. With this configuration, even if a curved route exists in the train route, and the two opposite face surfaces 30 approach while the train is running, the shock absorbers 21 attached to each of the face surfaces 30 are connected to each other. There is no contact. For this reason, it is not necessary to adjust the length of the shock absorber 21 in the longitudinal direction (the length of the hollow member 21a in the longitudinal direction) to be short, and the impact generated between the connected vehicles 10 can be absorbed with a simple configuration. The gap 5 can be closed.

  Further, since the shock absorber 21 is made of a hollow aluminum alloy, the shock compression force generated between the connected vehicles 10 can be sufficiently absorbed. Further, the structure of the shock absorbing device 100 is simplified, and the shock absorbing device 100 is excellent in maintainability. Furthermore, when only some of the shock absorbers 21 are damaged, only the damaged shock absorber 21 can be replaced.

  Further, since the shock absorber 21 is made of a hollow aluminum alloy having a strength lower than that of the vehicle body, the shock absorber 21 is surely plastically deformed and absorbs shock energy when it collides with the facing wife surface 30. Thereby, damage to the vehicle body can be reduced.

<Second Embodiment>
Next, a second embodiment of the vehicle and the impact absorbing device according to the present invention will be described with reference to FIG. In addition, about the thing similar to 1st Embodiment of this invention, it shows with the same code | symbol and abbreviate | omits description.

  In the shock absorber 200 in the second embodiment, a shock absorber 221 is used instead of the shock absorber 21 in the first embodiment. In addition, an elastic body 231 is provided at the tip of the shock absorber 221. The length in the longitudinal direction of the shock absorber 221 is shorter than the length in the longitudinal direction of the shock absorber 21 in the first embodiment. Other than this, the description is omitted because it is almost the same as the first embodiment.

[Shock absorber 221]
The shock absorber 221 in the present embodiment includes a rod-shaped hollow member 221a, a flat plate 21b that covers the front end of the hollow member, and a flat plate 21c that covers the rear end. The hollow member 221a has a day-shaped cross section with a partition formed at the center like the hollow member 21a in the first embodiment, and the length in the longitudinal direction is the same as that of the hollow member 21a in the first embodiment. The length is approximately half of the length in the longitudinal direction. The flat plates 21b and 21c are welded to each of the front end and the rear end of the hollow member 221a.

  When a sharp curve or the like is present on the train route, the following problems can be considered when the shock absorber having the same length as the length of the shock absorber 21 (hollow member 21a) in the first embodiment is used. For example, when the train travels on a sharp curve, the central axes of the vehicle bodies of the vehicles 210 connected to each other shift. Then, the shock absorbers 221 attached to the two facing wife surfaces 230 come into contact with each other, or the shock absorber 221 attached to the wife surface 230 comes into contact with the facing wife surface 230 to absorb the shock. It is conceivable that the body 221 is damaged. In order to suppress such damage to the shock absorber 221, in this embodiment, the length in the longitudinal direction of the shock absorber 221 (hollow member 221 a) is set to be longer than the length in the longitudinal direction of the shock absorber 221 in the first embodiment. It is shortened.

[Elastic body 231]
An elastic body 231 extends along the longitudinal direction of the shock absorber 221 at the tip of the shock absorber 221. As the elastic body 231, for example, an elastically deformable member such as elastic resin or rubber can be used. The elastic body 231 is attached to the flat plate 21b. The elastic body 231 is a rod-shaped member having substantially the same length as the length of the shock absorber 221 (hollow member 221a) in the longitudinal direction. When the shock absorber 221 is attached to the side end portion of the end face 230, the elastic body 231 extends in the longitudinal direction of the vehicle 210 as shown in FIG. The tip of the elastic body 231 is located near the center of the end face 230 that faces in the longitudinal direction. As described above, the gap 5 is closed by the shock absorber 221 and the elastic body 231. Even if the train has a sharp curve and the elastic body 231 comes into contact with the facing wife surface 230 while the train is running, the elastic body 231 is elastically deformed, and damage to the vehicle body can be suppressed.

  In addition, the shock absorber 221 (hollow member 221a) and the elastic body 231 in the present embodiment are formed to have substantially the same length, but the shapes of the shock absorber 221 and the elastic body 231 correspond to the train route. Can be changed as appropriate.

  As described above, the same effects as those of the first embodiment can be obtained also in the impact absorbing device 200 of this embodiment and the vehicle 201 that employs the impact absorbing device 200. In the present embodiment, the length of the shock absorber 221 (hollow member 221a) in the longitudinal direction is shorter than the length in the longitudinal direction of the shock absorber 21 in the first embodiment. Even if there is a sharp curve on the travel route, the shock absorbers 221 attached to the opposite wife surfaces 230 come into contact with each other or the shock absorber 221 contacts the opposite wife surface 230 while the train is running. Can be prevented. In addition, since the elastic body 231 extends at the tip of the shock absorber 221, the gap 5 can be closed by the shock absorber 221 and the elastic body 231. Thus, even if the shape (longitudinal length) of the shock absorber 221 (hollow member 221a) is changed according to the train route, the shock absorber 200 and the vehicle 201 have the shock absorption function and the fall prevention function. Demonstrate enough.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, the shapes and materials of the shock absorbers 21 and 221 and the elastic body 231 in the shock absorbers 100 and 200 in the above-described embodiment are examples, and the shock absorbers 21 and 221 and the elastic body 231 are formed in different shapes. Or different materials may be used.

Further, an impact absorbing device 300 is used instead of the impact absorbing device 100 in the first embodiment and the impact absorbing device 200 in the second embodiment. The impact absorbing device 300 includes a plate-like impact absorbing body 321 elongated in the height direction, and an elastic body 331 extending at the tip of the impact absorbing body 321. The shock absorber 321 is attached from the center to the lower end of the side end portion of the end face 330. Other than this, the description is omitted because it is almost the same as the first embodiment.

[Shock absorber 321]

For the shock absorber 321, foamed aluminum or the like can be used. The length in the width direction of the shock absorber 321 (the length in the horizontal direction of the plane of the shock absorber 321) is substantially the same as the length in the longitudinal direction of the shock absorber 221 in the second embodiment. Yes. A flat plate 321c made of an aluminum alloy is bonded to one long side surface of the shock absorber 321. The flat plate 321 c has a flat surface slightly larger than one side surface of the bonded shock absorber 321, and is fixed from a position slightly higher than the center to the lower end at the side end portion of the end face 330. The shock absorber 321 is attached to the side end of the end face 330 by fixing the flat plate 321c to the end face 330. The shock absorber 321 is attached to the side end of the end face 330 so that the plane faces the platform (in parallel with the longitudinal direction of the vehicle 310). In addition, a flat plate is bonded to the other side surface of the shock absorber 321, and an elastic body 331 is attached to the flat plate.

[Elastic body 331]
The elastic body 331 is a flat plate-like member having the same shape as the shock absorber 321. Like the elastic body 331 in the second embodiment, the elastic body 331 is a member that is elastically deformed, such as elastic resin or rubber, for example. Is used. The elastic body 331 is attached to the side surface of the shock absorber 321, and extends along the plane direction of the shock absorber 321.

  When the shock absorber 321 is attached to the side end of the end face 330, the tip of the elastic body 331 is located near the center between the two end faces 330 facing each other, as shown in FIG. As described above, the entire gap 5 from the vicinity of the center to the lower end in the height direction is closed by the shock absorber 321 and the elastic body 331.

  Thus, also in the modification 1, the effect similar to 1st Embodiment and 2nd Embodiment is acquired.

  Moreover, in the above-mentioned embodiment and modification, you may further attach an impact-absorbing body in the position where an outer holo is not provided. For example, impact energy can be further absorbed by further attaching an impact absorber at the position shown in the following modification. In addition, in the following modification, about the thing similar to 1st Embodiment and 2nd Embodiment of this invention, it shows with the same code | symbol and abbreviate | omits description.

<Modification 2>
As shown in FIGS. 5 and 6, the shock absorbing device 400 in this modification is configured to further attach the shock absorbing body 21 in the first embodiment to the upper end portion of the end face 430 and the upper end portions of the both sides of the vehicle 410. . On one end (left side) of the end face 430 shown in FIG. 6 (a), a predetermined distance is provided from the position where the shock absorber 21 is attached near the center of both ends to the upper end of the end face 430 upward. Two shock absorbers 21 are attached to both sides at a distance of. Further, on the opposite (right) end face 430 shown in FIG. 6 (b), the shock absorber is separated by a predetermined distance upward from the position where the shock absorber 21 is attached near the center of both end portions. One shock absorber 21 is attached to each side, and two shock absorbers 21 are attached to the upper end of the end face 430 with a predetermined distance in the left-right direction across the center portion. In this way, the shock absorbers 21 attached to the side ends of the two opposite face surfaces 430 are displaced from each other in the height direction. Further, the shock absorbers 21 attached to the upper end of the end face 430 are displaced from each other in the left-right direction. For this reason, when the end face 430 shown in FIG. 6A and the end face 430 shown in FIG. 6B are opposed to each other, the shock absorbers 21 attached to the respective end faces 430 do not face each other, and the vertical direction Or it shifts alternately in the left-right direction.

Further, when the shock absorber 221 and the elastic body 231 in the second embodiment are employed instead of the shock absorber 21, the same effects as in the second embodiment can be obtained. Furthermore, since the shock absorber 21 is disposed up to the upper portion of the gap 5 between the vehicles 410, the shock energy generated between the connected vehicles 410 can be more sufficiently absorbed.

  According to this modification, the same effect as that of the first embodiment can be obtained. Further, when the shock absorber 221 and the elastic body 231 in the second embodiment are employed instead of the shock absorber 21, the same effects as in the second embodiment can be obtained. Furthermore, impact energy can be absorbed even at a position close to the center of the end face 530 by the impact absorber 21 attached inside the side end of the end face 530. Thereby, the impact energy generated between the vehicles 510 connected to each other can be more sufficiently absorbed.
