A charging rail 100 according to an embodiment of the invention is described below with reference to fig. 1-17. The charging rail 100 of the embodiment of the invention can be applied to charging systems of various rail vehicles, for example, the charging system of a straddle type rail vehicle.

As shown in fig. 1, a charging rail 100 according to an embodiment of the first aspect of the present invention comprises: a shield 10 and a charging pad 20.

The protection cover 10 is provided with a placing space 11, the protection cover 10 is provided with a through groove 12 communicated with the placing space 11, the number of the charging plates 20 is two, the two charging plates 20 are arranged in the placing space 11, the charging grooves 21 opposite to the through groove 12 are limited by the two charging plates 20 at intervals, each charging plate 20 is provided with a plurality of rubber vibration reducing pieces 22 at intervals, and each rubber vibration reducing piece 22 is fixed on the protection cover 10.

Specifically, the through-groove 12 is provided in a side wall of the hood 10 (e.g., a top wall of the hood 10 in fig. 1) and extends in a longitudinal direction of the hood 10, the through-groove 12 penetrates the top wall of the hood 10 in a thickness direction of the top wall, the through-groove 12 is provided so as to face the charging groove 21 so that the charging blade 200 is inserted into the charging groove 21 through the through-groove 12, and the charging blade 200 is slidable in the through-groove 12 with respect to the charging groove 21.

When the charging system of the railway vehicle is charged, the charging blade 200 enters the charging slot 21 through the through slot 12, and in the process that the charging blade 200 slides along the charging slot 21, the charging blade 200 presses the charging plates 20 at two sides of the charging slot 21 to two sides, and a plurality of rubber vibration dampers 22 positioned between the charging plates 20 and the protective cover 10 are elastically deformed to play a role in buffering; the plurality of rubber dampers 22 apply an elastic force to the corresponding charging plate 20 toward the charging blade 200 by the elastic force to make the charging plate 20 closely contact the charging blade 200; after the charging blade 200 slides away from the charging slot 21, the plurality of rubber vibration dampers 22 are restored to the initial state due to the elastic action of the plurality of rubber vibration dampers 22, and at this time, the plurality of rubber vibration dampers 22 drive the corresponding charging plate 20 to move toward the direction close to another charging plate 20 so as to restore the charging plate 20 to the initial position.

According to some embodiments of the present invention, the charging rail 100 may extend in an extending direction of a running rail on which the rail vehicle runs. Specifically, the charging rail 100 may be disposed along the entire travel of the vehicle, so that the charging blade 200 may be always located in the charging slot 21 without being separated from the charging slot 21, and thus, the rail vehicle may be charged at any time during the running of the train, so that the rail vehicle may keep enough energy to run at any time.

Further, as shown in fig. 17, there are two tracks 300 on which the rail vehicle travels, the two tracks 300 are arranged side by side along the traveling direction of the rail vehicle, the charging rail 100 may be arranged between the two tracks 300, the length direction of the charging rail 100 is arranged parallel to the length direction of the tracks 300, and the charging blade 200 may be arranged at a position corresponding to the charging rail 100 at the bottom of the vehicle body, so as to facilitate the matching connection between the charging blade 200 and the charging rail 100.

In other embodiments of the present invention, the charging rail 100 may be disposed only within a platform region, which includes the platform and 50-150m extending forward and backward along the length of the rail. Thus, when the rail vehicle travels to the charging rail 100 when the vehicle arrives at a station, the charging blade 200 may move with the rail vehicle and enter the charging slot 21, so that the charging blade 200 is electrically connected to the two charging plates 20. Thus, the power storage device of the rail vehicle can be communicated with the power supply through the electrical connection between the charging blade 200 and the charging rail 100, and thus can be charged. When the rail vehicle leaves the station, the rail vehicle continues to run, the charging blade 200 continues to move along with the rail vehicle so that the charging blade 200 is separated from the charging groove 21, the electric connection between the power storage device of the rail vehicle and the power supply is disconnected, and the charging of the power storage device of the rail vehicle is completed. It can be understood that the rail vehicle may be stopped when the rail vehicle arrives at the station, and at this time, the charging blade 200 enters the charging slot 21 and remains relatively stationary with respect to the charging slot 21, so that the stability and reliability of the rail vehicle charging may be improved.

According to the charging rail 100 of the embodiment of the invention, the plurality of rubber vibration dampers 22 respectively connected with the protective cover 10 and the charging plate 20 are arranged, and the rubber vibration dampers 22 have elasticity, so that the plurality of rubber vibration dampers 22 can be elastically deformed and can apply damping force to the charging plate 20 while the charging blade 200 presses the charging plate 20 towards two sides in the charging slot 21 in the sliding process of the charging blade 200 in the charging slot 21, the charging blade 200 and the charging plate 20 can be in close contact, the current receiving state is ensured, the charging stability and the charging efficiency are improved, and after the charging blade 200 slides away from the charging slot 21, the charging plate 20 can be restored to the initial position by the elastic force of the plurality of rubber vibration dampers 22, and the effect of restoring the charging plate 20 is achieved. Secondly, the elastic force generated by the deformation of the plurality of rubber vibration dampers 22 can slow down the collision between the charging blade 200 and the charging plate 20, and play a role in buffering and protecting the charging plate 20 and the charging blade 200, thereby reducing the failure occurrence rate and prolonging the service life of the charging plate 20, and the plurality of rubber vibration dampers 22 have substantially no noise in the deformation process, so that the noise reduction function can be realized.

Furthermore, in the embodiment of the present invention, when a failure occurs in one of the plurality of rubber vibration dampers 22, only a single failed rubber vibration damper 22 needs to be detached, which has the advantages of convenient maintenance and low cost.

Therefore, the charging rail 100 according to the embodiment of the present invention has the advantages of simple structure, stable charging effect, low noise, adaptability to various severe environments, convenience in replacement, etc.

The rubber damper 22 of the charging rail 100 according to some embodiments of the present invention is described below with reference to fig. 2-6.

According to some embodiments of the present invention, as shown in fig. 2 to 6, the length direction of each rubber damper 22 is perpendicular to the length direction of the charging plate 20, and the peripheral wall of each rubber damper 22 is foldable in a direction parallel to the length direction thereof. It should be noted that the length direction of the charging plate 20 refers to the front-back direction shown in fig. 2 to 6, the width direction of the charging plate 20 refers to the left-right direction shown in fig. 2 to 6, and the length direction of the rubber damper 22 refers to the front-back direction shown in fig. 2 to 6, and for convenience of description, details in the following embodiments are omitted.

Specifically, as shown in fig. 2 and 3, the longitudinal direction of the rubber damper 22 is perpendicular to the longitudinal direction of the charging slot 21, both ends of the rubber damper 22 are stopped between the charging plate 20 and the protection cap 10, the portion of the rubber damper 22 where both end faces and the side face are connected is configured with a rounded corner, that is, the radial dimension of the rubber damper 22 adjacent to both end faces is gradually increased in the direction toward the end faces, and the peripheral wall of the rubber damper 22 where the end faces and the side face meet is formed in an arc structure in a section passing through the central axis thereof.

The peripheral wall of the rubber vibration damping member 22 is formed in a folded shape along the edge of the cross section parallel to the length direction thereof, as shown in fig. 4 and 5, the dimension of the rubber vibration damping member 22 in the radial direction thereof is constantly changed in the length direction thereof, and thus, when the rubber vibration damping member 22 is deformed in the length direction thereof, the elasticity is large, and the damping force provided to the charging plate 20 by the rubber vibration damping member 22 is large, thereby improving the buffering and vibration damping effects of the rubber vibration damping member 22 on the charging plate 20, making the contact effect between the charging blade 200 and the charging plate 20 better, and further improving the charging stability.

In some specific examples of the present invention, at least a part of the peripheral wall of each rubber damper 22 is formed in a wave shape in a section parallel to the length direction thereof. Specifically, the longitudinal direction of the rubber dampers 22 refers to the left-right direction in fig. 5, and at least a part of the peripheral wall of each rubber damper 22 in a cross section passing through the central axis thereof is formed into a wavy line, for example, the peripheral wall of the rubber damper 22 in fig. 5 is entirely configured into a wavy shape, i.e., the dimension of the rubber damper 22 in the radial direction thereof is regularly changed, whereby the shape of the peripheral wall of the rubber damper 22 is regular, the elastic effect of the rubber damper 22 in the axial direction thereof is better, and the cushioning and damping effects can be further improved.

In other specific examples of the present invention, at least a part of the peripheral wall of each rubber damper 22 is formed in the shape of a polyline along a section parallel to the lengthwise direction thereof. In other words, at least a part of the peripheral wall of the rubber damper 22 in a cross section passing through the central axis thereof is formed in a zigzag shape in which a plurality of broken lines are regularly connected.

In still other specific examples of the present invention, as shown in fig. 6, at least a part of the peripheral wall of each rubber damper 22 is formed in a shape of a multi-stage wave shape and a multi-stage broken line splice along a section parallel to the length direction thereof. Specifically, in the cross section passing through the central axis of each rubber vibration damping member 22, the peripheral wall of each rubber vibration damping member 22 is formed with a structure of a plurality of sections of wavy lines, two adjacent wavy lines are connected by straight line segments, and the straight line segments are parallel to the central axis of the rubber vibration damping member 22, so that the buffering and vibration damping effects of the rubber vibration damping member 22 are further improved, and the structural strength of the rubber vibration damping member 22 is also better.

According to some embodiments of the present invention, each rubber damper 22 is provided with a damper hole 221. Specifically, the rubber damper 22 is provided with at least one damper hole 221, for example, in the specific example shown in fig. 5, the rubber damper 22 may be provided with a plurality of damper holes 221 at intervals, each damper hole 221 extends from the outer peripheral wall of the rubber damper 22 in the radial direction of the rubber damper 22, that is, the extension direction of the damper hole 221 is perpendicular to the axial direction of the rubber damper 22, and the damper hole 221 penetrates through the side wall of the rubber damper 22 in the radial direction of the rubber damper 22. This can further increase the elasticity of the rubber damper 22, and the rubber damper 22 has a better damping effect on the charging plate 20. It should be noted that the cross-sectional shape of the damping hole 221 may be a circle or an ellipse, and the embodiment of the present invention is not particularly limited.

Alternatively, as shown in fig. 6, each rubber damper 22 is a hollow member. Specifically, a portion of the rubber damper 22 adjacent to the central axis is provided as a hollow, and the hollow portion extends in the axial direction of the rubber damper 22, and the hollow portion may extend from the inside of the rubber damper 22 to the end surface of the rubber damper 22 adjacent to the hood 10, that is, the hollow portion may penetrate from the inside of the rubber damper 22 to the end surface of the rubber damper 22 adjacent to the hood 10. Thus, the elasticity of the rubber damper 22 can be further improved. It is understood that in other embodiments of the present invention, the hollow portion inside the rubber damper 22 may be configured not to extend to the end surface of the rubber damper 22, i.e., the rubber damper 22 is partially hollow.

In some embodiments of the present invention, as shown in fig. 4 and 5, a plurality of fixing posts 223 are provided on the charging board 20, and one end of each rubber damper 22 is correspondingly provided with a fixing hole 222 matched with the fixing post 223, and one end of the rubber damper 22 is fixed on the charging board 20 by inserting the fixing post 223 into the fixing hole 222. Thus, the connection between the rubber vibration damper 22 and the charging plate 20 is convenient, and the fixing effect is good.

In some embodiments of the present invention, a bolt 224 is vulcanized to the other end of each rubber damper 22, and the bolt 224 is fixedly engaged with the shield 10 by a nut 225.

Specifically, a bolt 224 is vulcanization-fixed to an end of each rubber damper 22 adjacent to the hood 10, and a mounting hole that fits the bolt 224 is provided in an inner side surface of the hood 10, the mounting hole penetrating the hood 10 in a thickness direction of a side wall of the hood 10, and the bolt 224 passes through the mounting hole and is screw-fitted with a nut to fix the rubber damper 22 to the inner side wall of the hood 10. Therefore, the rubber vibration damper 22 and the protective cover 10 are fixed effectively, and the installation and the disassembly are convenient, so that the maintenance and the replacement of the rubber vibration damper 22 are convenient.

It should be noted here that the vulcanization refers to a vulcanization process performed when the rubber damper 22 is processed, that is, sulfur, carbon black, and the like are added to raw rubber and heated under high pressure to turn the raw rubber into vulcanized rubber, the vulcanized rubber damper 22 has good elasticity and heat resistance and good molding effect, and the bolt 224 is fixed at one end of the rubber damper 22 during the vulcanization of the rubber damper 22, so that the bolt 224 and the rubber damper 22 are fixed well and are not easy to fall off.

Rubber dampers 22 according to further embodiments of the present invention are described below with reference to fig. 7-9.

In other embodiments of the present invention, as shown in fig. 7-9, each rubber damper 22 is formed in a wave shape extending along the length of the charge plate 20. It should be noted here that the wave shape includes a sine wave shape, a rectangular wave shape, a zigzag shape, and the like, the length direction of each rubber damper 22 is parallel to the length direction of the charging plate 20, the length direction of the charging plate 20 is the front-back direction shown in fig. 7 to 9, the length direction of the rubber damper 22 is the front-back direction shown in fig. 7 to 9, and the width direction of the rubber damper 22 is the left-right direction shown in fig. 7 to 9, and for convenience of description, details in the following embodiments are not repeated.

Specifically, both side walls of each rubber damper 22 in the width direction are respectively abutted against the charging plate 20 and the protection cover 10, and each rubber damper 22 is deformed in the width direction thereof to perform a function of damping and cushioning the charging plate 20. The part of each rubber vibration damping piece 22 between the two side arms is formed into a wave shape, namely, a multi-section bending structure 227 is arranged between two side walls of the rubber vibration damping piece 22 in the width direction, and the multi-section bending structure 227 is foldable in the front and back directions, so that when the rubber vibration damping piece 22 deforms in the width direction, the elasticity is large, the damping force provided by the rubber vibration damping piece 22 to the charging plate 20 is large, the buffering and vibration damping effects of the rubber vibration damping piece 22 on the charging plate 20 are improved, the contact effect between the charging knife 200 and the charging plate 20 is good, and the charging stability is improved.

Further, the multi-stage bending structure 227 is formed by continuously bending a rectangular rubber plate in the longitudinal direction thereof, and the multi-stage bending structure 227 is formed in a shape of a sine wave, a rectangular wave, a polygonal line, or the like in a cross section in the thickness direction of the rubber damper 22.

For example, in the embodiment shown in fig. 9, the multi-stage bending structure 227 is formed in a sine wave shape, the sine wave shape is formed by splicing three half-arc structures, the end portions of the adjacent half-arc structures are connected, and the arc top of each half-arc structure is connected to the side wall of the rubber damper 22, so that the shape of the multi-stage bending structure 227 is regular, and the elastic effect of the rubber damper 22 is further improved. It is understood that in other embodiments of the present invention, the multi-stage bending structure 277 may be a rectangular rubber plate bent along its length to form a zigzag or rectangular wave shape.

Alternatively, as shown in fig. 9, two fixing plates 226 are fixed to each rubber damper 22, and the two fixing plates 226 of each rubber damper 22 are fixed to the corresponding charging plate 20 and the protection cover 10, respectively. Specifically, the two fixing plates 226 are respectively formed as two side walls in the width direction of the rubber damper 22, the multi-stage bending structure 227 is located between the two fixing plates 226, and the two fixing plates 226 are respectively fixed on the charging plate 20 and the protection cover 10, whereby the contact area between the rubber damper 22 and the charging plate 20 and between the rubber damper 22 and the protection cover 10 can be increased, thereby improving the elastic effect of the rubber damper 22 on the charging plate 20.

Further, one of the fixing plates 226 of each rubber vibration damper 22 is fixed to the hood 10 by a bolt and nut assembly. Therefore, the fixing effect of the rubber vibration damper 22 and the protective cover 10 is good, the connection mode between the rubber vibration damper 22 and the protective cover 10 is simple, and the rubber vibration damper 22 is convenient to mount and dismount.

According to some embodiments of the present invention, as shown in fig. 3 and 7, both end portions of each charging plate 20 are respectively bent away from the other charging plate 20. Specifically, the end of each charging plate 20 has a bent portion 23, the two bent portions 23 extend in directions away from each other, and the opening formed by the two bent portions 23 of the charging blade 200 enters the charging slot 21, so that the charging blade 200 can be prevented from colliding with the end of the charging blade 200 when entering the charging slot 21, and the charging blade 200 can be conveniently introduced into the charging slot 21.

In some embodiments of the invention, the camber angle of the end of each charging plate 20 is 7 ° to 13 °, where "camber angle" is understood to mean the angle between the bend 23 at the free end of each charging plate 20 and the direction of travel of the rail vehicle and away from the other charging plate 20.

According to some embodiments of the present invention, each of the charge plates 20 includes a multi-segment plate 40 sequentially connected in a traveling direction of the rail vehicle. Therefore, the two charging plates 20 are arranged into a plurality of sections which are connected in sequence, so that the contact distance between the charging blade 200 and the charging groove 21 formed between the two charging plates 20 can be prolonged, and the rail vehicle can charge enough electric quantity to the electric storage device in the running process, so that the rail vehicle has enough energy to run for a longer distance.

According to some embodiments of the present invention, adjacent two segment plates 40 are removably electrically connected. As shown in fig. 14, the respective ends of the adjacent two-stage plates 40 are electrically connected, and the adjacent two-stage plates 40 are connected in series. Furthermore, the joint between two adjacent segment plates 40 has a gap, so that the relative movement between two adjacent segment plates 40 can be realized. It should be noted that, a deviation in a certain direction may occur during the running process of the rail vehicle, and by making the adjacent segment plates 40 movably and electrically connected, the rail vehicle can smoothly transit at the connection between the adjacent segment plates 40, and the charging stability of the charging device is improved.

According to some embodiments of the present invention, as shown in fig. 10 to 16, one of the adjacent two-segment plates 40 is provided with a first extension 41, and the other is provided with a second extension 42 disposed at a distance, the first extension 41 and the second extension 42 extend toward each other end and the first extension 41 extends between the second extensions 42 to movably connect the adjacent two-segment plates 40.
