A charging device 1000 for a rail vehicle and a rail transit system according to an embodiment of the present invention will be described with reference to fig. 1 to 43.

As shown in fig. 1 to 43, a charging device 1000 for a rail vehicle according to an embodiment of a first aspect of the present invention is described, the charging device 1000 including: collector shoe 100 and charging rail 300.

Specifically, as shown in fig. 1, 6, and 7, the collector shoe 100 includes a charging blade 20, and the charging blade 20 is provided on the vehicle body. The charging rail 300 is provided with a groove body 630, the charging blade 20 moves relative to the groove body 630, and the charging blade 20 is electrically connected with the charging rail 300.

It should be noted that the trough 630 may extend along the driving direction of the vehicle, the vehicle body may be provided with an energy storage device, and the charging blade 20 may be electrically connected with the energy storage device. As the vehicle travels, the charging blade 20 moves relative to the slot 630 and the charging blade 20 is electrically connected to the charging rail 300. It should be noted that the charging blade 20 may be directly in contact with and electrically connected to the charging rail 300, or may be electrically connected to the charging rail through electromagnetic induction without direct contact. For example, the charging blade 20 may extend into the channel 630 and movably engage the channel 630. The term "removably engaged" as used herein is to be understood to mean that the charging blade 20 is slidably and electrically connected within the slot. Of course, when the vehicle stops and the charging blade 20 and the slot body 630 are kept relatively still, the charging blade 20 can be electrically connected with the charging rail 300 to charge the vehicle body, so that the stability and reliability of the charging of the rail vehicle can be improved.

According to the charging device 1000 for the rail vehicle, provided by the embodiment of the invention, the charging blade 20 is arranged on the vehicle body, and the charging blade 20 moves relative to the groove body 630 of the charging rail 300 and is electrically connected with the charging rail 300 so as to charge the vehicle body, so that the charging device is simple in structure and stable and reliable in charging. Moreover, the charging blade 20 can be slidably and electrically connected with the charging rail 300 along with the movement of the car body to charge the charging rail 300, so that the waiting time for parking and charging of the rail car can be reduced, and the charging of the rail car is more convenient and flexible.

According to some embodiments of the present invention, the collector shoe 100 may further include a sliding seat assembly 1 and an elastic restoring member 5, and the charging blade 20 is movably provided on the sliding seat assembly 1 in a transverse direction. The sliding seat assembly 1 is adapted to be connected to a car body of a railway vehicle, and the charging blade 20 is slidably connected to the sliding seat assembly 1 in a lateral direction, that is, the charging blade 20 is connected to the sliding seat assembly 1, and the charging blade 20 is slidable relative to the sliding seat assembly 1 in the lateral direction. The running direction of the rail vehicle is taken as the longitudinal direction, the direction perpendicular to the longitudinal direction is taken as the transverse direction, and the direction perpendicular to the longitudinal direction and the transverse direction is taken as the vertical direction. For example, in the example shown in fig. 6, the front-rear direction is a longitudinal direction, the left-right direction is a lateral direction, and the up-down direction is a vertical direction.

As shown in fig. 6, the elastic restoring member 5 may be connected to the charging blade 20 and the sliding seat assembly 1, respectively, and the elastic restoring member 5 may normally drive the charging blade 20 to be restored to an initial position in which the elastic restoring member 5 is in a natural state. It should be noted that the term "normally driven" is understood to mean that when the elastic restoring member 5 is subjected to a pressing force or a stretching force, the elastic restoring member 5 drives the movement tendency of the bracket 10a under the action of the elastic restoring force. The "initial position" generally refers to an optimum position where the charging blade 20 and the charging rail 300 are butted, which is determined by design, but the installation position of the charging rail 300 may vary due to mounting accuracy and the like. By providing the elastic restoring member 5, the offset of the charging blade 20 can be compensated when the vehicle body is offset, and the charging blade 20 can be restored to the initial position when the vehicle body is not offset. The "natural state" is understood to mean the natural state in which the elastic restoring element 5 is not compressed or tensioned. As shown in fig. 6 and 7, when the stand 10a deviates from the initial position, the elastic restoring member 5 may drive the stand 10a to restore to the initial position by the elastic restoring force.

That is, the charging blade 20 can move in a lateral direction relative to the sliding seat assembly 1, and the elastic restoring member 5 always drives the charging blade 20 to move to the initial position. Thus, when the rail vehicle deviates, the charging blade 20 tends to deviate relative to the charging rail 300, and at this time, the charging blade 20 slides relative to the sliding seat assembly 1, so that the charging blade 20 and the charging rail 300 form a better matching state to adapt to the deviation of the vehicle body; at the same time, the elastic restoring member 5 drives the charging blade 20 to move to the initial position. When the vehicle body is restored to the normal position from the offset position, the charging blade 20 is restored to the initial position under the driving of the elastic restoring member 5, and the charging blade 20 can also form a better fit state with the charging rail 300. Therefore, the vehicle charging device can be normally used under the extreme working conditions that the vehicle body deviates too much and the tire is blown out, the probability of generating -blade or -blade accidents is reduced, and the charging stability can be improved.

In some embodiments of the present invention, as shown in fig. 22-24, the charging rail 300 includes a first charging plate 610 and a second charging plate 620, the first charging plate 610 and the second charging plate 620 are both connected to a power source, the first charging plate 610 and the second charging plate 620 are arranged at a distance in the transverse direction to form a trough body 630, the trough body 630 has an inlet end 631 and an outlet end 632, the charging blade 300 is adapted to enter the trough body 630 from the inlet end 631 and separate from the trough body 630 from the outlet end 632, and when the charging blade 20 enters the trough body 630, the charging blade 20 is electrically connected to both the first charging plate 610 and the second charging plate 620. Thus, when the charging blade 20 enters the groove body 630 from the inlet end 631, the charging blade 20 can be electrically connected with the charging rail 300 to charge the vehicle body; when the charging blade 20 is separated from the outlet end 630, the charging blade 20 is electrically disconnected from the charging rail 300, and the charging blade 20 can enter or separate from the slot 630 along with the running of the vehicle, so that the charging of the rail vehicle can be conveniently controlled.

According to some embodiments of the present invention, the first charging plate 610 and the second charging plate 620 extend in a driving direction of the vehicle, and the first charging plate 610 and the second charging plate 620 may be disposed in parallel or may be disposed in an inclined manner with respect to each other, for example, in a top-down direction, the first charging plate 610 and the second charging plate 620 may be inclined toward each other, or in a bottom-up direction, the first charging plate 610 and the second charging plate 620 may be inclined toward each other. The first and

second charging plates

610 and 620 may be formed substantially as rectangular plates, and the facing surfaces of the first and

second charging plates

610 and 620 may be configured as a plane or a curved surface.

In some embodiments of the present invention, the cross-sections of the first and

second charging plates

610 and 620 may each be configured as a curve or a broken line, and the first and

second charging plates

610 and 620 are protruded toward each other.

According to some embodiments of the present invention, the charging rail 300 may extend in an extension direction of a running rail on which the rail vehicle runs, and the extension length of the charging rail 300 is not less than the extension length of the running rail. In other words, the charging rail 300 may be disposed along the entire stroke of the vehicle. At this time, the charging blade 20 may be always located in the slot 630 without being separated from the slot 630, 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. The charging rail 300 may be disposed between two rails of a running rail of the rail vehicle, and the charging blade 20 may be disposed at a corresponding position at the bottom of the vehicle body, so as to facilitate the mating connection of the charging blade 20 and the charging rail 300.

In some embodiments of the present invention, charging rail 300 may be provided only within a platform region including the platform and 50-150m extending fore and aft along the length of the rail. . Thus, when the rail vehicle travels to the charging rail 300 when the vehicle arrives at a station, the charging blade 20 may move along with the rail vehicle and enter the chute body 630 from the inlet end 631, such that the charging blade 20 is electrically connected to the first charging plate 610 and the second charging plate 620. Thus, the energy storage device of the rail vehicle can be connected to the power supply through the electrical connection between the charging blade 20 and the charging rail 300, and thus can be charged. When the rail vehicle leaves the station, the rail vehicle continues to run, the charging blade 20 continues to move along with the rail vehicle, so that the charging blade 20 is separated from the groove body 630, the electric connection between the energy storage device of the rail vehicle and the power supply is disconnected, and the energy storage device of the rail vehicle is charged. It can be understood that when the rail vehicle arrives at the station, the rail vehicle can be stopped, and at this time, the charging blade 20 enters the slot 630 and keeps standing relative to the slot 630, so that the stability and reliability of the rail vehicle charging can be improved.

According to some embodiments of the present invention, the collector shoe 100 may be provided at the bottom of the vehicle body, and the charging blade 20 may be movably and/or rotatably provided at the bottom of the vehicle body. That is, the charging blade 20 is movable relative to the vehicle body, or the charging blade 20 is rotatable relative to the vehicle body, or the charging blade 20 is both movable and rotatable relative to the vehicle body. It should be noted that the "rotation" described herein may include: deflection, flipping, pivoting, and rotation, etc., wherein the manner of rotation may be understood as the charging blade 20 being rotatable about its central axis. When the charging blade 20 needs to extend into the slot 630, the charging blade 20 may be rotated to an angle that allows the charging blade 20 to extend into the slot 630, and then moved downward to extend into the slot 630.

For example, when the rail vehicle needs to be charged, the charging blade 20 may be movably extended or rotatably extended from the bottom of the vehicle body, or extended in a manner of moving and rotating in coordination with the movement, so that the charging blade 20 enters the slot 630 to charge the rail vehicle; when the charging of the rail vehicle is completed, the charging blade 20 may be moved upward and retracted into the vehicle body or the charging blade 20 may be retracted by rotation, or the charging blade 20 may be retracted by a combination of movement and rotation. So as to avoid potential safety hazards such as interference or power exposure of the charging knife 20 in the running process of the rail vehicle.

It should be noted that the "charging blade 20 is extended and retracted rotationally" is understood to mean that the charging blade 20 is rotatable relative to the vehicle body. For example, the bracket 10a may be provided at the bottom of the car body, the charging blade 20 may be connected to the bracket 10a by a rotating shaft, and the charging blade 20 may rotate along the length direction, the width direction, or other angular directions of the train around the rotating shaft, so as to facilitate the extension and retraction of the charging blade 20. When the charging blade 20 is rotated to extend, the charging blade 20 may be perpendicular to the bottom wall of the vehicle body, and when the charging blade 20 is rotated to retract, the charging blade 20 may be attached to the bottom wall of the vehicle body.

According to some embodiments of the present invention, the collector shoe 100 may further include a bracket 10a, the bracket 10a is movably disposed on the sliding seat assembly 1 in the transverse direction, the charging blade 20 is disposed on the bracket 10a, and two ends of the elastic restoring member 5 respectively abut against the bracket 10a and the sliding seat assembly 1. That is, the support frame 10a is connected to the slide carriage assembly 1, and the support frame 10a is slidable in the lateral direction with respect to the slide carriage assembly 1.

As shown in fig. 5, the charging blade 20 is connected to the bracket 10a such that when the bracket 10a slides relative to the sliding seat assembly 1, the charging blade 20 slides along with the bracket 10a, so that the charging blade 20 can move in the lateral direction relative to the bracket 10a assembly, so that the charging blade 20 can move in the width direction of the car body relative to the railway car. Therefore, the influence of a skimming knife or a skimming rail caused by the deviation of the vehicle body can be effectively reduced, and the charging stability is improved. The elastic restoring member 5 is connected to the bracket 10a and the sliding seat assembly 1, respectively, so that the elastic restoring member 5 can normally drive the bracket 10a to restore to a natural state.

As shown in fig. 6, 8 and 9, the sliding seat assembly 1 may be formed with a sliding groove 11 extending in the transverse direction, and the bracket 10a is slidably engaged with the sliding groove 11 in the transverse direction. That is, the bracket 10a slides along the slide groove 11 of the slide seat assembly 1. Simple structure, the processing of being convenient for, moreover convenient assembling.

Therefore, the support 10a can slide in the sliding groove 11 along the transverse direction, and the support 10a can be prevented from being disengaged from the sliding groove 11 in the vertical direction, so that the stability is good, and the reliability is high.

Further, the chute 11 may be opened downward. That is, the slide seat assembly 1 is formed with a slide groove 11 extending in the transverse direction and being opened downward in the vertical direction, and the slide groove 11 is configured as a structure tapered downward in the vertical direction, and the bracket 10a is configured as a structure contracted downward in conformity with the slide groove 11, the bracket 10a being adapted to be fitted in the slide groove 11 and the bracket 10a being slidable in the transverse direction along the slide groove 11. Therefore, the bracket 10a can be prevented from being separated from the sliding groove 11 under the action of self gravity through the shape of the sliding groove 11, and the structure is simple and the design is ingenious.

Alternatively, in the example shown in fig. 9, the slide groove 11 may be formed as a trapezoidal groove whose inner side surface is a slope, and a cross section of the bracket 10a perpendicular to the transverse direction is formed as a trapezoid which can be fitted with the trapezoidal groove. Of course, the sliding groove 11 and the bracket 10a may be formed to be matched with other shapes, for example, the inner side surface of the sliding groove 11 forms a cylindrical surface, and the side surface of the bracket 10a forms a cylindrical surface. And no limitation of the invention is thereby intended.

In order to improve the sliding flexibility and the smoothness of the bracket 10a in the sliding groove 11, an oil storage groove 12 may be provided on at least one of the inner side surface of the sliding groove 11 and the side surface of the bracket 10a, and lubricating oil or grease or the like may be stored in the oil storage groove 12. In other words, the oil reservoir 12 is formed on the side of the sliding seat, as shown in fig. 9; alternatively, the oil reservoir 12 may be formed on the inner side surface of the chute 11; alternatively, the oil reservoir 12 may be provided on both the bracket 10a and the inner surface of the chute 11. Therefore, the friction force between the bracket 10a and the sliding groove 11 can be reduced, so that the bracket 10a can flexibly and smoothly slide in the sliding groove 11 along the transverse direction, and meanwhile, the abrasion is reduced, and the noise is reduced.

According to some embodiments of the present invention, as shown in fig. 6 and 7, the support frame 10a is provided with a support 102, the elastic restoring member 5 may include two elastic members 51, the two elastic members 51 are distributed on two sides of the support 102, which are opposite to each other in the transverse direction, and the elastic members 51 may be connected to the support 102 and the sliding seat assembly 1. Referring to the example shown in fig. 6 to 9, a support 102 is provided on the upper surface of the bracket 10a, two elastic members 51 are connected to the left and right sides of the support 102, respectively, and the two elastic members 51 are connected to the sliding seat assembly 1, respectively. In this way, the two elastic members 51 can elastically connect the bracket 10a and the sliding seat assembly 1 at two sides, so that the bracket 10a can be allowed to slide in the sliding groove 11 through elastic deformation of the elastic members 51, and the elastic members 51 can normally drive the bracket 10a to return to a natural state due to the characteristics of restoring original state.

In some embodiments, as shown in fig. 6 and 7, the elastic member 51 may be a spring, and the bracket 10a is provided with a receiving groove 103, the receiving groove 103 may extend in a transverse direction, and at least a portion of the elastic member 51 may be received in the receiving groove 103. For example, two accommodating grooves 103 with openings facing upward are formed on the upper surface of the bracket 10a, and two springs are accommodated in the accommodating grooves 103, respectively. From this, can provide installation space for elastic component 51 through storage tank 103, spatial layout is reasonable, can make the structure compacter, in addition, can also provide spacingly for elastic component 51 through storage tank 103, avoids elastic component 51 to become invalid because of taking place the dislocation, can improve stability and reliability.

It should be noted that the elastic member 51 for offset return may be replaced by other elastic members such as a rubber spring and an air spring, or may be replaced by a pneumatic system having an active control system. As will be appreciated by those skilled in the art, will not be described in detail herein.

Alternatively, the support 102 may include two protrusions 1021, as shown in fig. 7 and 9, the two protrusions 1021 may be arranged at intervals in the transverse direction, and the two protrusions 1021 may be distributed on two sides of a connection portion of the charging blade 20 and the support 10a, on one hand, an abdicating space may be provided for the connection of the charging blade 20 and the support 10a, so as to improve space utilization, and on the other hand, the installation stability of the elastic member 51 may be improved.

According to some embodiments of the present invention, the charging blade 20 is provided on the stand 10a movably in the vertical direction. As shown in fig. 6, the charging blade 20 is movably connected to the bracket 10a in a vertical direction, which is a direction perpendicular to the horizontal direction, and in the example shown in fig. 6, the up-down direction shown in fig. 6 is the vertical direction. That is, the charging blade 20 can move not only in the lateral direction but also in the vertical direction. From this, both can adapt to the skew of automobile body on its width direction, also can cushion and charge sword 20 and charge vertical ascending collision when rail 300 contact, simple structure is compact, and buffering effect is good, and charging stability and reliability are higher.

According to some embodiments of the present invention, as shown in fig. 5, the bracket 10a may be provided with a through hole 101, and the collector shoe 100 may further include a moving rod 21, one end of the moving rod 21 is movably engaged with the through hole 101, and the other end of the moving rod 201 is provided on the charging blade 20. Specifically, one end (e.g., the upper end shown in fig. 5) of the moving rod 21 is movably inserted into the through hole 101, and the charging blade 20 may be connected to the other end (i.e., the lower end shown in fig. 5) of the moving rod 21, and the charging blade 20 may contact the charging rail 300 to receive current during charging, in other words, in the example shown in fig. 1 to 3, the moving rod 21 may move in the up-down direction within the through hole 101 while the charging blade 20 moves in the up-down direction, during which the charging blade 20 may be moved in the up-down direction by the moving rod 21,

according to some embodiments of the present invention, the collector shoe 100 may further include a buffer member 3, and both ends of the buffer member 3 are respectively connected to the charging blade 20 and the bracket 10a to buffer the vertical movement of the charging blade 20. The buffer 3 may connect the bracket 10a and the moving rod 21. The buffer member 3 is connected to the bracket 10a and the moving rod 21, respectively, to provide a buffer for the charging blade 20 to alleviate the collision between the charging blade 20 and the charging rail 300.

In some embodiments of the invention, the buffer 3 may be an elastic element, for example, the buffer 3 may be a spring as shown in fig. 1; alternatively, the buffer 3 may be an automatically controllable electric push rod (not shown) or an automatically controllable air cylinder (not shown). Therefore, the buffer member 3 can deform under stress, and can provide damping force for preventing relative displacement between the charging knife 20 and the support 10a, so that the structure is simple and compact, the assembly and disassembly are convenient, and the buffering effect is good. Here, the "automatically controllable electric push rod" means an electric push rod having an active control function, and the "automatically controllable cylinder" means a cylinder having an active control function.

Alternatively, as shown in fig. 1 to fig. 3, the buffer member 3 may be sleeved on the outer peripheral surface of the moving rod 21, on one hand, the occupied space of the buffer member 3 may be reduced, the structural layout may be optimized, and on the other hand, the buffer member 3 may be utilized to provide a stable and uniform buffer force, so that the buffer effect is further improved.

To facilitate the mounting and positioning of the cushion member 3, the moving rod 21 may have a stopper boss 211, and the cushion member 3 may be stopped between the bracket 10a and the stopper boss 211. During assembly, the buffer member 3 is firstly sleeved on the moving rod 21, one end (for example, the upper end shown in fig. 5) of the moving rod 21 extends into the through hole 101 of the bracket 10a, so that one end of the buffer member 3 is stopped against the bracket 10a, and the other end (for example, the lower end shown in fig. 5) is stopped against the stop boss 211, thereby realizing assembly and positioning, having low assembly difficulty and improving assembly efficiency.

Alternatively, the stopper boss 211 may be an annular boss, i.e., the stopper boss 211 may be configured in a closed loop shape around the circumference of the moving bar 21. From this, backstop boss 211 can supply bolster 3 backstops in whole circumference, and the backstop is effectual, can avoid the backstop to become invalid, can effectively improve stability and buffering reliability.

Of course, the structure of the present invention is not limited to this, and the stop bosses 211 may be provided in plural at intervals in the circumferential direction of the moving rod 21, which should not be construed as limiting the present invention. Here, "plurality" is to be understood as at least two, for example three, four or five, in order to stop the buffer 3 stably against the stop cams 211.

As shown in fig. 1 and 3, one end (e.g., the upper end shown in fig. 2 and 3) of the moving rod 21 may be mounted with a stopper 22 that moves with the moving rod 21, the stopper 22 being located at a side (e.g., the upper side shown in fig. 2 and 3) of the bracket 10a facing away from the charging blade 20. For example, in the example shown in fig. 3, when the moving rod 21 moves downward to the lowest position, the stopper 22 stops against the upper side of the bracket 10a to restrict the moving rod 21 from continuing downward, so that the moving rod 21 can be prevented from coming out of the through hole 101; when the moving rod 21 moves upward, the limiting member 22 can move upward synchronously with the moving rod 21. Therefore, the structure is simple and compact, and the buffering stability can be further improved.

Alternatively, the limiting member 22 may be a limiting pin passing through the moving rod 21; alternatively, as shown in fig. 1 to 3, the limiting member 22 may be a limiting nut in threaded fit with the end of the moving rod 21, which is easy to assemble and disassemble, good in stability and low in cost.

According to some embodiments of the present invention, as shown in fig. 2 and 5, a support portion 4 may be connected to the bracket 10a, and the support portion 4 includes: a plurality of support rods 41 and a collar 42, wherein one end (e.g., the upper end shown in fig. 5) of each support rod 41 may be connected to the support 10a and each support rod 41 extends toward a direction away from the support 10a (i.e., downward as shown in fig. 5), and the collar 42 may be connected to the other end (i.e., the lower end as shown in fig. 5) of the plurality of support rods 41, wherein the moving rod 21 is movably nested in the collar 42. From this, the lantern ring 42 can be supported by the bracing piece 41 and fix on support 10a to the lantern ring 42 is spaced apart from support 10a, and carriage release lever 21 can move in lantern ring 42 and through-hole 101, through setting up the lantern ring 42 that links to each other with support 10a, can improve the stationarity that carriage release lever 21 removed, and simultaneously, lantern ring 42 still can provide the direction for carriage release lever 21, avoids appearing carriage release lever 21 because of taking place the skew and block the phenomenon that can't move in through-hole 101, can effective reliability.

Advantageously, the support rods 41 may include at least two spaced around the collar 42, for example, the support rods 41 may be two as shown in fig. 5, or the support rods 41 may be three, four, etc., the support rods 41 may be inclined toward the collar 42 in a direction away from the bracket 10a (e.g., in a downward direction as shown in fig. 5), and the other end of the support plate (i.e., the lower end as shown in fig. 5) may be connected to the outer peripheral surface of the collar 42. Therefore, the plurality of support rods 41 can provide support for the collar 42 in the circumferential direction, and the stability and reliability of the collar 42 can be improved, thereby facilitating the telescopic movement of the movable rod 21.

In order to avoid the movement rod 21 from rotating around its axial direction during the telescopic movement, a stopper 23 may be provided between the movement rod 21 and the collar 42 for stopping the movement. For example, as shown in fig. 5, the limiting portion 23 may be a rectangular key, an installation key slot may be formed in the outer peripheral surface of the moving rod 21, a through key slot may be formed in the inner peripheral surface of the collar 42, the rectangular key is installed in the installation key slot, and when the moving rod 21 moves, the rectangular key is driven to vertically move in the through key slot, so that the moving rod 21 is limited to rotate around the axial direction thereof while moving vertically, thereby preventing the charging blade 20 from rotating and improving reliability.

The charging blade 20 will be described in detail below with reference to the drawings.

As shown in fig. 14 to 16, the charging blade 20 may extend in a longitudinal direction (e.g., a front-rear direction shown in fig. 14 and 16), and the charging blade 20 may be provided with a first current-receiving surface 201 and a second current-receiving surface 202 on laterally opposite sides, respectively. That is, the charging blade 20 has a first current receiving surface 201 and a second current receiving surface 202 formed on its respective laterally opposite side surfaces. That is, the charging blade 20 has two oppositely disposed current receiving surfaces.

Wherein, in the vertical direction, the distance between the first flow receiving surface 201 and the second flow receiving surface 202 gradually decreases from the first end to the second end. The "first end" herein may be understood as an upper end of the charging blade 20, and the "second end" may be understood as a lower end of the charging blade 20. For example, in the example shown in fig. 15, the spacing between the first flow receiving surface 201 and the second flow receiving surface 202 gradually decreases from the upper end to the lower end. Alternatively, the distance between the first flow receiving surface 201 and the second flow receiving surface 202 may be gradually decreased from the lower end to the upper end.

From this, can utilize first surface 201 that receives the class and second surface 202 that receives the class and the contact of charging rail 300, realize two-sided receiving, increased the area that receives the class, can optimize the state of receiving the class, and, the interval between first surface 201 that receives the class and the second surface 202 that receives the class changes, can guarantee to charge sword 20 and the rail 300 between have certain contact pressure, compare in the upper and lower single face contact current collection mode among the correlation technique, can improve the contact stability of sword 20 with the rail 300 that charges, thereby can effectively improve and receive class stability, reduce the probability that the electric spark appears, the security has been improved.

According to some embodiments of the present invention, one of the first flow receiving surface 201 and the second flow receiving surface 202 may extend in a vertical direction, and the other thereof extends obliquely with respect to the vertical direction; alternatively, the first flow receiving surface 201 and the second flow receiving surface 202 extend obliquely in a direction toward each other. Therefore, the first current receiving surface 201 and the second current receiving surface 202 of the charging blade 20 can be configured into different shapes to be matched with the charging rails 300 with different structures, the structure is simple, and the processing is convenient.

Alternatively, the charging blade 20 extends in the longitudinal direction and the transverse direction, and the charging blade 20 has a shape gradually contracting from the first end edge to the second end edge in a vertical section. For example, in the example shown in fig. 15, the charging blade 20 has a shape gradually shrinking to the edge of the charging blade 20 in the direction away from the holder 10a, that is, the charging blade 20 gradually shrinks from the upper end edge to the lower end edge. Therefore, two lateral surfaces of the charging blade 20 opposite in the transverse direction can be respectively configured into the first flow receiving surface 201 and the second flow receiving surface 202, the flow receiving area is larger, and the stability and the reliability are better.

In some embodiments, the cross-sectional area of the charging blade 20 decreases gradually toward at least one end in the longitudinal direction. In other words, as shown in fig. 16, at least one of both end portions of the charging blade 20 in the longitudinal direction may have a shape gradually contracted to the edge of the charging blade 20 in the longitudinal direction. For example, in the example shown in fig. 16, the cross-sectional area of the front end of the charging blade 20 gradually decreases forward, and the cross-sectional area of the rear end of the charging blade 20 gradually decreases rearward, i.e., the charging blade 20 is configured as a bidirectional wedge, and the double-sided contact collects current. Therefore, the guide slopes 2061 may be formed at the front and rear ends of the charging blade 20, and thus the guide slopes 2061 may serve as a guide for guiding the charging blade 20 into the slot 630.

The "bidirectional wedge shape" means a structure in which the charging blade 20 gradually changes from wide to narrow from the first end to the second end in a side view, and gradually changes from wide at the middle to narrow at both ends in a top view. Of course, the structure of the present invention is not limited thereto, and the charging blade 20 may also be configured in a shape in which the cross-section of the end first contacting the charging rail 300 is gradually reduced toward the cross-section.

It can be understood that, when rail vehicle marchd, the tip of sword 20 that charges earlier with the rail 300 contact that charges, through with the sword 20 design that charges for reducing gradually to the tip on vertical, can provide the guide effect, do benefit to sword 20 that charges and the smooth contact of rail 300 and cooperation, not only can alleviate the collision, reduce wearing and tearing, can improve the cooperation precision moreover, and then can provide the stability of charging.

According to some embodiments of the present invention, the charging blade 20 may be provided with a receiving groove 203 adapted to mount the wire lug 24, and the receiving groove 203 may be provided at a first end of the charging blade 20. Alternatively, the receiving groove 203 may extend to the first end of the charging blade 20 in the vertical direction. Alternatively, the accommodating groove 203 may penetrate the first flow receiving surface 201 and the second flow receiving surface 202 in the lateral direction. For example, as shown in fig. 12 to 16, the upper end of the charging blade 20 is provided with a receiving groove 203, the receiving groove 203 is configured as a three-sided opening groove extending vertically to the upper end surface of the charging blade 20 and extending laterally to the first and second

flow receiving surfaces

201 and 202, respectively, and the line nose 24 is mounted in the receiving groove 203. Therefore, the wire nose 24 is convenient to machine and manufacture, and the installation and the positioning of the wire nose are convenient to realize, the type is more compact, the current collection stability is good, the reliability is high, and the assembly efficiency is high.

According to some embodiments of the present invention, as shown in fig. 22, the charging blade 20 may include a connecting portion 205 and a body portion 206, a lower end of the connecting portion 205 is connected to the body portion 206, and an upper end of the connecting portion 205 is connected to the moving bar 21.

According to some embodiments of the present invention, the charging rail 300 is also optimally designed.

As shown in fig. 17 to 21, two surfaces of the groove 630 in the lateral direction form a first supply surface 61 and a second supply surface 62, respectively. That is, the groove 630 has two flow supply surfaces disposed opposite to each other.

Wherein the spacing between the first and second flow surfaces 61, 62 in the vertical direction gradually decreases from the first end to the second end. For example, in the example shown in fig. 17, the interval between the first and second flow supply surfaces 61 and 62 is gradually reduced from the upper end to the lower end. Alternatively, the distance between the first and second flow surfaces 61 and 62 may be gradually decreased from the lower end to the upper end.

From this, can utilize the first supply surface 61 and the second supply surface 62 of rail car that charges 300 and the sword 20 contact that charges of rail car, realize two-sided confession and flow, can increase the confession and flow the area, and, the interval between first supply surface 61 and the second supply surface 62 changes, can guarantee to have certain contact pressure between sword 20 and the cell body 630 charges, can improve the contact stability of rail 300 and the sword 20 that charges, thereby can improve charging stability, can reduce the probability that the electric spark appears, and the security also can improve.

According to some embodiments of the invention, the channel body 630 may be a resilient channel. That is, the groove 630 has a characteristic of being elastically deformed when being applied with a force, and is restored to its original shape when the external force is released. From this, when sword 20 charges and the contact of rail 300 that charges, the cooperation of sword 20 that charges to the cell body 630 in, at this moment, certain elastic deformation can take place for cell body 630 to can utilize self elastic restoring force to form "centre gripping" power to sword 20 charges, provide contact pressure for sword 20 charges from horizontal both sides, can further improve the stability of receiving a current of the contact surface that charges, optimize and receive a current quality.

In some embodiments, as shown in fig. 17 and 21, the charging rail 300 may further include: laterally opposite first and second

outer side panels

611 and 612. Wherein a first end (e.g., an upper end shown in fig. 13) of the first outer side plate 611 may be spaced apart from a first end (i.e., an upper end shown in fig. 17) of the second outer side plate 612, and a second end (i.e., a lower end shown in fig. 17) of the first outer side plate 611 is connected to a second end (i.e., a lower end shown in fig. 17) of the second outer side plate 612. The first charging plate 610 and the second charging plate 620 are positioned between the first outer side plate 611 and the second outer side plate 612, a first end of the first charging plate 610 is connected to a first end of the first outer side plate 611, a first end of the second charging plate 620 is connected to a first end of the second outer side plate 612, and the first charging plate 610 and the second charging plate 620 extend obliquely toward each other. Wherein the opposite surfaces of the first and

second charging plates

610 and 620 form the first and second current supply surfaces 61 and 62, respectively.

From this, can be with the rail 300 design of charging for hollow "shell form" type, construct the rail 300 that charges for semi-rigid rail 300 that charges, can not only alleviate the dead weight of rail 300 that charges, can optimize structure moreover, be convenient for manufacturing, can reduce cost. Compared with a rigid contact rail and a flexible contact network in the related art, the semi-rigid charging rail 300 can generate certain elastic deformation, so that contact pressure is provided by utilizing self elastic recovery clamping force, and stable current collection of a charging contact surface is ensured.

Alternatively, as shown in fig. 17 and 20, a portion of the first outer side plate 611 may be recessed toward the second outer side plate 612 to form the first groove 601, and a portion of the second outer side plate 612 may be recessed toward the first outer side plate 611 to form the second groove 602. Alternatively, the first and

second grooves

601 and 602 may be oppositely disposed. In this way, by designing the first and

second grooves

601 and 602, the strength of the first and second side plates may be enhanced, so that the strength of the charging rail 300 may be improved, and the first and

second grooves

601 and 602 may also facilitate the installation and positioning of the charging rail 300, which will be described in detail below in connection with specific embodiments.

Advantageously, the second end of the first charging plate 610 and the second end of the second charging plate 620 may be bent in directions away from each other. Specifically, in the example shown in fig. 17, the lower end of the first charging plate 610 is bent away from the second charging plate 620, and the lower end of the second charging plate 620 is bent away from the first charging plate 610. From this, the free end of first charging panel 610 and second charging panel 620 can be buckled respectively and form the inner hook, on the one hand, do benefit to and form smooth first supply surface 61 and second supply surface 62, make the structure of rail 300 that charges compacter, be convenient for charge sword 20 and the cooperation of cell body 630, on the other hand, can effectively avoid charging sword 20 and rail 300 that charges to take place the scraping, form promptly and prevent scraping inner hook 65, the wearing and tearing have been alleviateed, the noise reduction, and can also reduce the appearance of electric spark.

As shown in fig. 17 and 21, the second end of the first charging plate 610 may be spaced apart from the first groove 601 in the vertical direction, and the second end of the second charging plate 620 may be spaced apart from the second groove 602 in the vertical direction. In other words, in a projection in the longitudinal direction, the free end of the first charging plate 610 is disposed spaced apart from the first groove 601, and the free end of the second charging plate 620 is disposed spaced apart from the second groove 602. When charging sword 20 and cell body 630 contact charge, the sword 20 that charges contacts with first charging panel 610 and second charging panel 620 respectively, set up through the second section with first charging panel 610 and first recess 601 interval, and set up second end and the second recess 602 interval of second charging panel 620, can provide the space for the deformation of first charging panel 610 and second charging panel 620, avoid taking place to interfere, can make the elastic characteristic of rail 300 that charges effectively exert, do benefit to and realize stably receiving the current.

Alternatively, the charging rail 300 may be a symmetrical structure. Preferably, the charging rail 300 may be a metal piece formed integrally, that is, the first outer side plate 611, the second outer side plate 612, the first charging plate 610 and the second charging plate 620 may be formed integrally. For example, the charging rail 300 may be rolled from a thin sheet metal piece.

Therefore, the flow supply effect can be optimized, the processing is convenient, and the cost can be reduced. In addition, the metal piece has better rigidity and toughness, and the charging rail 300 can exert better elastic characteristics while the charging rail 300 has certain rigidity by matching with the shape of the charging rail 300, so that the effect of adding one to one and being more than two is realized, and the current collection quality and the charging stability are better.

In order to facilitate the drainage of rainwater and silt deposited in the trough 630, the charging rail 300 may be provided with a drainage hole 66 communicated with the trough 630. Advantageously, the drain hole 66 may be provided at the lowest surface in the gravity direction after the charging rail 300 is installed. Therefore, silt and rainwater accumulated in the groove body 630 can be automatically discharged from the sewage hole 66 under the action of gravity, manual operation is not needed, maintenance investment is reduced, and safety can be improved.

According to some embodiments of the present invention, as shown in fig. 18 and 19, the first and

second charging plates

610 and 620 located at the inlet and outlet ends 631 and 632 are bent toward a direction away from each other to be configured as the guide section 63, and it should be noted that the inlet and outlet ends 631 and 632 described herein may be understood as being determined according to a traveling direction of the rail vehicle. It will be appreciated that the rail vehicle may travel in a reverse direction, and that the inlet end 631 and outlet end 632 of the charging rail 300 are reversed when the rail vehicle is traveling in the reverse direction, as opposed to when the rail vehicle is traveling in the forward direction. The guide section 63 has a guide groove 64 communicating with the groove 630, and laterally opposite surfaces of the guide groove 64 are divergent in a direction away from the groove 630. In other words, in the traveling direction of the railway vehicle, one or both ends of the charging rail 300 are provided with the guide sections 63, the guide sections 63 have the guide grooves 64, the guide grooves 64 communicate with the groove body 630, and the lateral dimensions of the guide grooves 64 gradually increase in a direction away from the groove body 630.

Therefore, in the process of advancing the rail vehicle, the charging blade 20 moves synchronously with the vehicle body, and when the rail vehicle advances to a station area for charging, the charging blade 20 moves into the groove body 630 from one end and contacts with the charging rail 300. The guide section 63 is provided at the end of the charging rail 300, so that the charging blade 20 can be moved into the guide groove 64 and then into the slot body 630, and since the guide groove 64 is configured to be gradually enlarged away from the slot body 630, the guide groove 64 can provide a guide function for the charging blade 20, so that the charging blade 20 can smoothly transit from the non-charging rail 300 region to the charging rail 300 region. Thus, the charging blade 20 can be prevented from violently colliding with the charging rail 300, the probability of damage is reduced, and the service life can be prolonged.

The guiding section 63 forms a bifurcated guiding belt, and due to the existence of the side bifurcation, when the charging blade 20 slides into the charging rail 300, the contact force between the charging blade 20 and the contact surface of the charging rail 300 tends to be gradually increased, and when the charging blade 20 slides out of the charging rail 300, the contact force between the charging blade 20 and the contact surface of the charging rail 300 tends to be gradually decreased. Under the combined action of this contact force and the buffer 3, the charging blade 20 moves vertically toward the bracket 10a when the rail vehicle is approaching, and moves away from the bracket 10a when the rail vehicle is exiting.

Therefore, by monitoring the position change condition of the charging blade 20, the charging loop is communicated when the station-entering displacement is dynamic, and the charging loop is disconnected when the station-exiting displacement is dynamic, so that the purpose of 'rear path and front disconnection' can be achieved, and the occurrence of arcing possibly occurring at the moment of contact or disconnection between the collector shoe 100 and the charging rail 300 can be reduced. The term "rear contact, before disconnection" means that the charging circuit is turned on after the collector shoe 100 comes into contact with the charging rail 300, and the charging circuit is turned off just before the collector shoe 100 comes out of contact with the charging rail 300.

Alternatively, when the charging blade 20 contacts the slot 630, the first current receiving surface 201 of the charging blade 20 may contact the first current supplying surface 61 of the slot 630, and the second current receiving surface 202 of the charging blade 20 may contact the second current supplying surface 62 of the slot 630. That is, the charging blade 20 is in double-sided contact with the chute body 630. That is, the charging blade 20 and the trough 630 are charged by a double-sided current collection method, which is not only simple and compact in structure, but also high in current collection reliability and good in stability, compared with a top-bottom single-sided contact current collection method adopted in the prior art.

To ensure that the charging blade 20 maintains an optimal fit after contact with the channel 630, the charging blade 20 is interference fit with the channel 630. In other words, in the free state, the interval between the first and second flow supply surfaces 61 and 62 of the groove body 630 is smaller than the width of the charging blade 20 at the corresponding positions of the first and second

flow receiving surfaces

201 and 202. Or, an included angle formed between the first current receiving surface 201 and the second current receiving surface 202 of the charging blade 20 is not smaller than an included angle formed between the first current supplying surface 61 and the second current supplying surface 62 of the charging rail 300 in a free state. Accordingly, when the charging blade 20 slides in the slot 630, the first and second current receiving

surfaces

201 and 202 of the charging blade 20 stably press the first and second current supply surfaces 61 and 62 of the slot 630, and the current receiving stability can be improved.

According to some embodiments of the present invention, as shown in fig. 22-24, the charging rail 300 may further include a housing 640, the first charging plate 610 and the second charging plate 620 are both connected to the housing 640 by a connection assembly 650, and the first charging plate 610 and the second charging plate 620 are both movable relative to the housing 640. Thus, in one aspect, the connection assembly 650 may securely fix the first and

second charging plates

610 and 620 to the housing 640; on the other hand, the connection assembly 650 may provide a pushing force to the first and

second charging plates

610 and 620 to ensure reliability and stability of the electrical connection between the first and

second charging plates

610 and 620 and the charging blade 20.

When the charging blade 20 enters the chute 630, the charging blade 20 abuts against the first charging plate 610 and the second charging plate 620 so that the first charging plate 610 and the second charging plate 620 move in a direction away from each other, and when the charging blade 20 is detached from the chute 630, the first charging plate 610 and the second charging plate 620 move in a direction close to each other.

It should be noted that, as shown in fig. 22 to 24, when the charging blade 20 enters the chute body 630 from the inlet end 631, the first charging plate 610 and the second charging plate 620 both contact the charging blade 20 to achieve electrical connection, and at the same time, the charging blade 20 presses the first charging plate 610 and the second charging plate 620, so that the first charging plate 610 and the second charging plate 620 move away from each other; when the charging blade 20 is detached from the slot 630, the first charging plate 610 and the second charging plate 620 move toward a direction close to each other, and thus, when the charging blade 20 enters the slot 630, the first charging plate 610 and the second charging plate 620 tightly clamp the charging blade 20, and the reliability and stability of the electrical connection between the first charging plate 610 and the second charging plate 620 and the charging blade 20 can be improved. Furthermore, the closed clamping of the charging device 1000 is realized by controlling the movement of the first charging plate 610 and the second charging plate 620 through the connection assembly 650, and thus, the structure of the charging blade 20 can be simplified, the overall weight of the rail vehicle can be reduced, and the overall structure of the rail vehicle is simpler and lighter.

In some embodiments of the present invention, as shown in fig. 23 and 24, the connection assembly 650 may include: an outer barrel 651, an inner barrel 652 and a restoring member 653.

As shown in fig. 24, the outer cylinder 651 is connected to the housing 640. Thus, by providing the outer cylinder 651, the assembly connection between the connection assembly 650 and the housing 640 is facilitated. As shown in fig. 24, the outer cylinder 651 may be fixedly assembled with the housing 640 by bolts. The first end 6521 of the inner cylinder 652 is slidably received in the outer cylinder 651, and the second end 6522 of the inner cylinder 652 is connected to the first charging plate 610 or the second charging plate 620. Therefore, the first charging plate 610 or the second charging plate 620 can be moved by the relative sliding between the inner cylinder 652 and the outer cylinder 651. One end of the restoring member 653 is positioned on the outer cylinder 651, and the other end of the restoring member 653 is positioned on the corresponding first charging pad 610 or second charging pad 620. Thus, the inner cylinder 652 can be urged to return to the original position by the elastic restoring force of the restoring member 653.

As shown in fig. 22-24, when the charging blade 20 enters the slot 630, the charging blade 20 presses the first charging plate 610 and the second charging plate 620, so that the inner cylinder 652 slides along the second end 6522 towards the first end 6521, thereby moving the first charging plate 610 and the second charging plate 620 away from each other, and at this time, the first charging plate 610 or the second charging plate 620 presses the corresponding restoring member 653, so that the restoring member 653 is elastically deformed; when the charging blade 20 is separated from the slot body 630, under the elastic restoring force of the restoring member 653, the inner cylinder 652 slides along the first end 6521 towards the second end 6522, so that the first charging plate 610 and the second charging plate 620 move towards each other, so as to ensure that the first charging plate 610 and the second charging plate 620 can clamp the charging blade 20 when the charging blade 20 enters the slot body 630 next time, and the stability and reliability of the electrical connection between the first charging plate 610 and the second charging plate 620 and the charging blade 20 are improved.

According to some embodiments of the present invention, as shown in fig. 24, 37-39, the connection assembly 650 may further include a hinge assembly 660, one end of the hinge assembly 660 is connected to the first charging plate 610 or the second charging plate 620, the other end of the hinge assembly 660 is rotatably connected to the second end 6522 of the inner cylinder 652 by a pin 661, and the other end of the restoring member 653 is stopped against the hinge assembly 660.

In some embodiments of the invention, the restoring member 653 may be a spring, as shown in fig. 23, and in other embodiments of the invention, the restoring member 653 may also be a rubber or other elastic member.

It should be noted that, when the rail vehicle runs and drives the charging blade 20 to enter the trough body 630 from the inlet end 631, the charging blade 20 contacts the first charging plate 610 and the second charging plate 620 and generates an impact, and by providing the hinge assembly 660, the first charging plate 610 and the second charging plate 620 can rotate in a small range by using the pin 661 as a rotating shaft, so that the impact generated by the charging blade 20 on the charging rail 300 can be buffered and absorbed, and the noise can be reduced and the service life of the charging rail 300 can be prolonged.

In some embodiments of the present invention, as shown in FIG. 24, the coupling assembly 650 can further include a stop block 670, the stop block 670 coupled to the first end 6521 of the inner barrel 652. As shown in FIG. 24, the first end 6521 of the inner cylinder 652 has an open mouth, the inner circumferential wall of which can be internally threaded, and the stop block 670 extends into the open mouth and is threadedly coupled to the inner cylinder 652. Therefore, the firmness and reliability of fixing the limit block 670 and the inner cylinder 652 can be improved.

As shown in fig. 24, the stopper 670 has a positioning portion 671 located outside the outer cylinder 651, and the positioning portion 671 is adapted to abut against the outer cylinder 651 to limit the displacement of the inner cylinder 652. As shown in fig. 24, the diameter of the end of the stopper 670 is larger than the diameters of the rest positions to form a position stop portion 671, and the position stop portion 671 may be a bolt connected to the end of the stopper 670 or may be formed by extending a flange from the end of the stopper 670. The positioning portion 671 can restrict the movement distance of the inner cylinder 652. For example, when the inner cylinder 652 moves in a direction from the first end 6521 to the second end 6522, and after the inner cylinder 652 moves to a predetermined distance, the positioning portion 671 can abut against the end of the outer cylinder 651, so as to restrict further movement of the inner cylinder 652, thereby preventing the first charging plate 610 from colliding with the second charging plate 620 to generate noise and electric spark, and improving the stability of the operation of the charging rail 300.

Further, as shown in fig. 24, a buffer member 672 is provided between the positioning portion 671 and the outer cylinder 651. Therefore, when the inner cylinder 652 moves to the second end 6522 along the first end 6521 to a predetermined distance, the position stop portion 671 collides with the end of the outer cylinder 651 to stop, and the buffer member 672 can buffer and absorb the collision impact between the position stop portion 671 and the end of the outer cylinder 651, so that the noise of the charging rail 300 can be reduced, the collision damage of the components in the charging rail 300 can be effectively avoided, and the service life of the charging rail 300 is prolonged.

According to some embodiments of the present invention, as shown in fig. 24, the charging rail 300 may further include a shield 680, the housing 640 is provided with a telescopic hole 641, and the first end 6521 of the inner cylinder 652 penetrates through the telescopic hole 641 and is sleeved in the shield 680. From this, can improve casing 640 and the fastness and the reliability of coupling assembling 650 being connected, can play the insulating effect of isolation moreover, avoid charging rail 300 to have the electric leakage hidden danger. As shown in fig. 24, the shield 680 is inserted into the housing 640 and is stopped by the release member 672 and the housing 640, thereby improving the fixation between the inner cylinder 652 and the housing 640. The shield 680 may be an insulator to isolate the inner barrel 652 from the charging rail 300.

In some embodiments of the present invention, as shown in fig. 25, each of the first and

second charging plates

610 and 620 may include a multi-segment plate 600 sequentially connected in a traveling direction of the rail vehicle. Therefore, the first charging plate 610 and the second charging plate 620 are arranged into a plurality of sections which are connected in sequence, so that the contact distance between the charging blade 20 and the first charging plate 610 and the second charging plate 620 can be prolonged, and the rail vehicle can be charged with enough electric quantity to the energy storage device in the running process, so that the rail vehicle has enough energy to run for a longer distance.

Further, adjacent two segment plates 600 are removably electrically connected. As shown in fig. 25 and 26, the adjacent two segment plates 600 are electrically connected to each other through a cable connecting block 6003, so that the adjacent two segment plates 600 are connected in series. Moreover, a gap is formed at the joint between two adjacent segment plates 600, so that the two adjacent segment plates 600 can move relatively. 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 600 movably and electrically connected, the rail vehicle can smoothly transit at the connection between the adjacent segment plates 600, and the charging stability of the charging device 1000 is improved.

According to some embodiments of the present invention, as shown in fig. 25 to 32, one of the two adjacent segments 600 is provided with a first extension plate 6001, and the other is provided with a second extension plate 6002 disposed at a distance, the first extension plate 6001 and the second extension plate 6002 extend toward each other, and the first extension plate 6001 extends into between the second extension plates 6002 so as to movably connect the two adjacent segments 600. It should be noted that, as shown in fig. 28, the first extension plate 6001 extends into the gap between two second extension plates 6002 which are spaced apart from each other, and the first extension plate 6001 and the second extension plate 6002 have a gap therebetween without contacting each other, so that the adjacent two segment plates 600 can be moved relative to each other to facilitate the transition of the charging blade 20 between the adjacent two segment plates 600.

As shown in fig. 29, the rail vehicle normally runs and drives the charging plate to transit from the section plate 600 with the second extension plate 6002 arranged at intervals to the section plate 600 with the first extension plate 6001; as shown in fig. 30, when the rail vehicle is shifted toward the segment plate 600 in the drawing, the segment plate 600 having the second extension plate 6002 is pressed by the charging blade 20 to move away from the segment plate 600 having the first extension plate 6001, while the segment plate 600 having the first extension plate 6001, which is not in contact with the charging blade 20, is in the normal position, and the first extension plate 6001 may guide the charging blade 20 to smoothly transition from the segment plate 600 having the second extension plate 6002 to the segment plate 600 having the first extension plate 6001. When the charging blade 20 is transitioned to the segment plate 600 having the first extension plate 6001, the second extension plate 6002 is restored to the normal position by an elastic restoring force. Similarly, as shown in fig. 31, when the rail vehicle is shifted toward the other direction, the first extension plate 6001 and the second extension plate 6002 may also guide the smooth transition of the charging blade 20 between the adjacent segment plates 600, improving the charging stability and reliability of the charging device 1000.

According to other embodiments of the present invention, as shown in fig. 33 and 34, one of the two adjacent segment plates 600 is provided with a first extension plate 6001, and the other is provided with a second extension plate 6002, and the first extension plate 6001 and the second extension plate 6002 are provided at intervals in the up-down direction. As shown in fig. 33, the first extension plate 6001 and the second extension plate 6002 of two adjacent segment plates 600 may be inclined outward in the same direction, and the first extension plate 6001 and the second extension plate 6002 of a plurality of segment plates 600 may be inclined outward in different directions alternately.

In some embodiments of the present invention, the camber angle of the first charging plate 610 at the location of the inlet end 631 and the outlet end 632 is 7 ° to 13 °, where "camber angle" is understood to mean an angle between a free end of the first charging plate 610 and a direction of travel of the rail vehicle and away from the second charging plate 620. Similarly, the camber angle of the second charging plate 620 at the positions of the inlet end 631 and the outlet end 632 is 7 ° to 13 °, and the term "camber angle" as used herein is understood to mean an angle between the free end of the second charging plate 620 and the traveling direction of the rail vehicle and away from the first charging plate 610.

According to some embodiments of the present invention, as shown in fig. 40, at least one of the facing surfaces of the first charging plate 610 and the second charging plate 620 is provided with a flexible member 6004. That is, the flexible member 6004 may be provided on the surface of the first charging plate 610, the flexible member 6004 may be provided on the surface of the second charging plate 620, or the flexible member 6004 may be provided on both the surfaces of the first charging plate 610 and the second charging plate 620. The flexible member 6004 may be disposed near upper or lower edges of the first charging plate 610 and the second charging plate 620. Therefore, the flexible member 6004 is conveniently and fixedly connected to the first charging plate 610 and the second charging plate 620, and the flexible member 6004 is disposed near the upper edge or the lower edge of the first charging plate 610 and the second charging plate 620, so that the flexible member 6004 can be prevented from interfering with the electrical connection between the charging blade 20 and the first charging plate 610 and the second charging plate 620, and the charging stability and reliability of the charging rail 300 can be improved.

In some embodiments of the present invention, as shown in fig. 40, the flexible member 6004 may be plural, and the plural flexible members 6004 are provided at intervals in the traveling direction of the rail vehicle. Therefore, by arranging the plurality of flexible members 6004 at intervals in the traveling direction of the rail vehicle, the buffering noise reduction effect of the flexible members 6004 can be improved, and moreover, the material usage amount of the flexible members 6004 can be saved and the assembly labor of the flexible members 6004 and the first and

second charging plates

610 and 620 can be reduced, so that the production efficiency can be improved and the production cost can be reduced.

According to some embodiments of the present invention, as shown in fig. 40, a shielding portion 642 is disposed on the top of the housing 640 to prevent dust and impurities from entering the groove 630 to affect the normal operation of the charging rail 300, and the shielding portion 642 may be flexible bristles or the like.

In some embodiments of the present invention, as shown in fig. 41, a side of the outer cylinder 651 close to the restoring member 653 may be provided with a stopper 6511, and the stopper 6511 cooperates with the inner cylinder 652 to limit the displacement of the inner cylinder 652. Thus, damage to the charging rail 300 due to an excessive moving distance of the inner cylinder 652 can be prevented. As shown in fig. 41, when the inner cylinder 652 moves along the second end 6522 toward the first end 6521, the limit portion 6511 can stop against the restoring member 653 to limit further movement of the inner cylinder 652, so that damage to the charging rail 300 caused by an excessive moving distance of the inner cylinder 652 can be avoided.

According to some embodiments of the present invention, as shown in fig. 41, the charging slot rail 300 may further include a fixing plate 647, the fixing plate 647 is sleeved on the outer cylinder 651, and the fixing plate 647 is fixed on the housing 640. For example, the fixing plate 647 may be fixed to the housing 640 by bolts to improve the firmness and reliability of the fixation between the fixing plate 647 and the housing 640. As shown in fig. 41, the fixing plate 647 is sleeved on the outer portion 651, and the fixing plate 647 abuts against the limit portion 6511. This can improve the firmness and reliability between the outer cylinder 651 and the housing 640.

According to some embodiments of the present invention, as shown in fig. 42, the end portion of the first end 6521 of the inner cylinder 652 is provided with a stopper 6523, the stopper 6523 is stopped against the end portions of the outer cylinders 651, and a stopper 6524 is provided between the stopper 6523 and the end portion of the outer cylinder 651. Therefore, when the inner cylinder 652 moves a certain distance along the first end 6521 to the second end 6522, the stopper 6523 can stop against the end of the outer cylinder 651, so as to limit further movement of the inner cylinder 652, avoid the first charging plate 610 and the second charging plate 620 from colliding, and reduce the operation noise of the charging rail 300. Moreover, the stopping piece 6524 can absorb the collision between the buffer inner cylinder 652 and the outer cylinder 651, thereby further reducing the operation noise of the charging rail 300 and improving the operation stability and reliability of the charging rail 300.

In some embodiments of the present invention, as shown in fig. 42, the stop 6524 may be configured in a ring shape and the stop 6524 may be sleeved on the inner cylinder 652. Therefore, the processing and the manufacturing of the stopping piece 6524 are convenient, and the assembly of the stopping piece 6524 is convenient, so that the production efficiency can be improved, and the production cost can be reduced.

In some embodiments of the present invention, as shown in fig. 42, the protective cover 690 may be an insulating member, and the protective cover 690 fixes the housing 640 by the protective cover 680 to improve the insulation protection effect of the charging rail 300.

That is, the controller controls whether the power supply device supplies power according to whether the charging blade 20 and the slot body 630 are in contact. When the detection device detects that the charging knife 20 is not in contact with the slot body 630, the controller controls the power supply device not to supply power, and when the detection device detects that the charging knife 20 is in contact with the slot body 630, the controller controls the power supply device to supply power, so that a charging loop is switched on to charge the power storage device; when the detection device detects that the charging blade 20 is separated from the trough body 630, the control device controls the power supply device to stop supplying power, disconnects the charging loop and stops charging the power storage device.

That is, the contact path and the open circuit before disconnection can be realized according to the relative position of the charging knife 20 and the groove body 630, so that the arcing phenomenon can be effectively avoided, and the charging safety can be further improved.

Alternatively, the detection means may be a displacement sensor that detects a displacement between the charging blade 20 and the chute body 630, or the detection means may be a pressure sensor that detects a force applied to the chute body 630.

Specifically, the insulator 400 includes an insulating support 71 and an insulating pressing block 72, the insulating support 71 has a mounting groove 710, a portion of the charging rail 300 fits in the mounting groove 710, and the insulating pressing block 72 is fixed on the insulating support 71 by a bolt, wherein the insulating pressing block 72 extends out of the first groove 601 and the second groove 602 of the charging rail 300 and is pressed on the side surfaces of the first groove 601 and the second groove 602, so as to realize a fastening effect on the charging rail 300.

The charging rail 300 may be two symmetrical parts, and the figure illustrates a cross section of the charging rail 300, where each part includes the anti-scraping inner hook 65, the contact rail section, the rail top, the rail web, the groove bottom section, the groove oblique section, the rail seat straight section, the rail seat oblique section and the rail seat bottom section which are connected in sequence, and the rail seat bottom sections of the two parts are connected.

The railway vehicle has a collector shoe 100, and the collector shoe 100 is connected to an electric storage device in the vehicle body. Wherein, collector shoe 100 mainly includes: the sliding seat assembly 1, the bracket 10a, the charging blade 20, the elastic reset piece 5 and the buffer piece 3.

Wherein, sliding seat assembly 1 links firmly through the insulating seat 200 of fastener and automobile body, but support 10a and sliding seat assembly 1 realize translation through the dovetail groove cooperation mode and connect, but other subassemblies are all direct or indirect to be installed on support 10 a: including charging sword 20, carriage release lever 21 passes through the through-hole 101 on lantern ring 42 and the support 10a, and the periphery cover of carriage release lever 21 is equipped with bolster 3, and carriage release lever 21 lower extreme links to each other with charging sword 20, and the carriage release lever 21 upper end is fixed through stop nut, makes bolster 3 possess certain compressive capacity, prevents to break away from support 10a because of the spring action, and carriage release lever 21 passes through the fastener with charging sword 20 and links to each other.

In the free state of the charging knife 20, the buffer member 3 is in a compressed state, so that the charging knife 20 always keeps a downward movement trend, but keeps the original position due to the limiting action of the movable rod 21 and the limiting nut. In the process of running until the charging blade 20 is completely inserted into the groove 630 through the bifurcated guide belt, due to the action of the guide groove 64 and the existence of the contact surface inclination angle, the charging blade 20 is acted by a resultant force in the direction of the moving rod 21, and the resultant force overcomes the compression force of the buffer member 3 at the moment, so that the moving rod 21 moves upwards until the charging blade 20 is stably contacted with the charging rail 300.

Fig. 14-16 are three views of the charging blade 20. Because the current collection type that the side surface of the charging knife 20 is contacted is adopted, in order to ensure certain contact pressure, the knife-groove matching surfaces are inclined at a certain angle, the charging knife 20 is specially made into a wedge shape, the whole shape is that the width of the upper part is gradually narrowed downwards, and the front guide surface and the rear guide surface are gradually widened towards the middle part. Wherein, there is holding tank 203 in the middle part position of the sword 20 that charges, and this holding tank 203 size and line nose 24 size phase-match. Fig. 12 and 13 show the state of the wire lug 24 before and after installation, respectively, when the wire lug 24 is inserted into the corresponding position of the accommodating groove 203, and the stable connection between the wire lug 24 and the charging blade 20 is realized by using a hexagon socket head cap screw.

The elastic reset piece 5 comprises two symmetrically distributed springs, one end of each spring is pressed against the sliding seat assembly 1, the other end of each spring acts on the support 102 of the support 10a, each spring has a certain pre-pressing amount, the support 10a is provided with a containing groove 103 for installing the spring, and the spring is determined to be between the sliding seat assembly 1 and the support 10a and contained in the containing groove 103 so as to prevent the spring from jumping out and play a limiting role.

The offset compensation function is mainly realized by the sliding seat assembly 1, the bracket 10a and two springs. The sliding seat assembly 1 is matched with the bracket 10a through a trapezoidal groove, so that the bracket 10a can smoothly slide back and forth along the transverse direction relative to the sliding seat assembly 1; the two springs are symmetrically arranged under prepressing, one end of each spring acts on the fixedly connected sliding seat assembly 1, the other end of each spring acts on the slidable bracket 10a, and when the bracket 10a does not bear the acting force along the axial direction of the spring, the bracket 10a is in a middle initial position, namely a balance position, under the action of the symmetrical prepressing force; when the external force is applied, the balance relation of the two springs is broken, the support 10a starts to move towards the force-applying direction, and after the external force disappears, the support 10a returns to the balance position under the action of the pre-pressure.

Due to the existence of the support 102 of the bracket 10a, the bracket 10a cannot be assembled by using a manner of end sliding, in some embodiments, a lateral embedded assembly method may be adopted, and the sliding seat assembly 1 includes a first sliding seat 111 extending along the transverse direction and a second sliding seat 112 extending along the transverse direction, which are fixedly connected by bolts.

Wherein a trapezoidal groove is formed between the first slider seat 111 and the second slider seat 112, and the holder 10a is configured as a trapezoidal wedge. After assembly, the two springs are respectively located between the sliding seat assembly 1 and the bracket 10a and lie on the receiving groove 103. Because both springs are in a compressed state, the position of the spring can be limited by matching the sliding seat assembly 1 with a cover on the upper part of the accommodating groove 103. In addition, the sliding contact surface of the holder 10a is opened with an oil reservoir 12 in the sliding direction, so that the lubricating effect of the sliding contact surface is maintained as much as possible and friction is reduced.

Comparing fig. 10 and fig. 11, when the charging knife 20 is subjected to the left acting force, the bracket 10a will move along the trapezoidal groove to the force-receiving direction, the bias spring on the force-receiving side is compressed for the second time, the spring on the other side is relaxed, and the same applies to the right side when receiving the force; when the device is in a free state, the device is finally stabilized at the middle initial position under the action of the balance force of the two springs, and the offset compensation function can be realized.
