Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A charging device 100 for a rail vehicle according to an embodiment of the present invention, which charging device 100 can charge a rail vehicle, is described below with reference to fig. 1 to 16.

As shown in fig. 1 to 2, a charging device 100 for a rail vehicle according to an embodiment of the present invention includes: charging panel 1, link 2 and charging sword 3.

The charging panel 1 may be disposed in an escape space 200a of a track beam 200 of a railway vehicle, and the connecting frame 2 may be connected to the charging panel 1 to drive the charging panel 1 to move up and down relative to the track beam 200. Specifically, the connecting frame 2 can drive the charging plate 1 to move up and down, so that the relative height between the charging plate 1 and the charging blade 3 can be adjusted, and the collision between the charging blade 3 and the charging plate 1 can be reduced, so that the working noise of the charging device 100 can be reduced, and the service lives of the charging blade 3 and the charging plate 1 can be prolonged.

For example, when the distance between the charging blade 3 and the charging plate 1 in the vertical direction is small, the connecting frame 2 may drive the charging plate 1 to move upward to a set position. When the distance between the charging blade 3 and the charging plate 1 in the vertical direction is large, the connecting frame 2 can also drive the charging plate 1 to move downwards to the setting position. From this, through above-mentioned setting, the link 2 can just contact so that charging sword 3 and charging panel 1 through adjusting charging panel 1 position on the vertical direction, can play the dual function of alleviating the collision and noise reduction.

As shown in fig. 2, the charging blade 3 may include a charging blade 31 and a connecting assembly 32, both ends of the connecting assembly 32 may be connected to the car body of the railway vehicle and the charging blade 31, respectively, the charging blade 31 may be moved to a lower side of the charging plate 1 to be in contact with the bottom surface of the charging plate 1 to form an electrical connection, and the charging blade 31 may be rotated relative to the connecting assembly 32 to buffer the impact force. Specifically, the charging blade 3 may move synchronously with the car body, and when the rail car enters the station, the charging blade 31 may move to the bottom of the charging plate 1 and make an electrical connection with the charging plate 1. Wherein, the charging blade 31 may be provided with a charging cable, and the charging cable is electrically connected to the vehicle body, so that a charging loop may be formed among the charging plate 1, the charging blade 31, the charging cable and the vehicle body to charge the vehicle body.

Because the charging blade 31 is rotatable relative to the connecting assembly 32, when the charging blade 31 is slidably engaged with the charging plate 1, if the charging blade 31 encounters an obstacle, the charging blade 31 can rotate relative to the connecting assembly 32 in a direction away from the obstacle under the action of an impact force, so that the impact force between the obstacle and the charging blade 31 can be buffered, the charging blade 31 can be prevented from being deformed and broken by the force, and the service life of the charging blade 31 can be prolonged. It should be noted that the "obstacle" in the above description may be the charging plate 1, or may be foreign matter entering the track beam 200.

The charging device 100 for a rail vehicle according to the present invention is described in detail below with a specific embodiment.

The charging device 100 includes a charging panel 1, a connecting frame 2 and a charging blade 3, the charging panel 1 is disposed in an escape space 200a of a track beam 200 at a platform position, and the charging panel 1 is plural and spaced apart in a traveling direction of the rail vehicle. Every charging panel 1 all links to each other with the link 2 that corresponds, and link 2 can drive the relative track roof beam 200 of charging panel 1 that corresponds and reciprocate. The number of the charging blades 3 is multiple, and the plurality of the charging blades 3 are arranged at intervals in the length direction of the railway vehicle and are arranged in one-to-one correspondence with the plurality of the charging plates 1. Each charging blade 3 includes a charging blade 31 and a connecting assembly 32, and both ends of the connecting assembly 32 may be connected to the body of the rail vehicle and the charging blade 31, respectively. Each charging blade 31 is provided with a charging cable, and the charging cable is electrically connected with the vehicle body.

When the rail vehicle enters a station, the charging blade 3 positioned at the foremost side of the vehicle body is firstly contacted with the charging panel 1 at the rearmost side, the connecting frame 2 can adjust the position of the charging panel 1 in the vertical direction so that the charging blade 3 is just contacted with the charging panel 1, and the charging blade 31 is in sliding fit with the charging panel 1. Thus, when the rail vehicle travels to the charging position, the plurality of charging blades 31 correspond to the plurality of charging plates 1 one to one and move to the bottom of the corresponding charging plate 1, and the charging blades 31 are electrically connected to the corresponding charging plate 1 to charge the rail vehicle. Wherein, when rail vehicle drives the sword 3 that charges and removes to the position of charging, if the blade 31 that charges meets the obstacle and blocks, the blade 31 that charges can rotate towards the direction of keeping away from the obstacle by coupling assembling 32 relatively under the effect of collision force, can cushion the collision force between obstacle and the blade 31 that charges from this, can prevent to charge the blade 31 atress and take place to warp and break, and then can prolong the life of the blade 31 that charges.

According to the charging device 100 for the rail vehicle, the connecting frame 2 is arranged to drive the charging plate 1 to move up and down, so that the relative height between the charging plate 1 and the charging blade 3 can be conveniently adjusted to enable the charging blade 3 to be just contacted with the charging plate 1, and double effects of reducing collision and noise can be achieved. By arranging the charging blade 31 to be rotatable with respect to the connecting assembly 32, the collision force between the obstacle and the charging blade 31 can be buffered, and the charging blade 31 can be prevented from being deformed and broken after collision, so that the service life of the charging blade 31 can be prolonged.

As shown in fig. 4, according to some embodiments of the present invention, the charging device 100 may further include a positioning device 4, the positioning device 4 may include a first positioning member 41 and a second positioning member 42, the charging blade 31 may be provided with the first positioning member 41, the connecting assembly 32 may be provided with the second positioning member 42, and the positioning device 4 may be configured such that after the charging blade 31 rotates relative to the connecting assembly 32, the first positioning member 41 may cooperate with the second positioning member 42 to position the charging blade 31 at the current rotation position. Thus, with the above arrangement, the charging blade 31 can be prevented from rebounding after being rotated, and further, a secondary collision between the charging blade 31 and an obstacle can be prevented, and the collision loss of the charging blade 31 can be further reduced.

In some embodiments of the present invention, as shown in fig. 5, the first positioning member 41 may be one of a ratchet wheel 41a and a pawl 42a, the second positioning member 42 may be the other of the ratchet wheel 41a and the pawl 42a, and the pawl 42a and the ratchet wheel 41a are engaged. For example, the first positioning member 41 may be a ratchet wheel 41a, and the second positioning member 42 may be a pawl 42 a. For another example, the second positioning member 42 may be a ratchet wheel 41a, and the first positioning member 41 may be a pawl 42 a. It can be understood that the ratchet mechanism formed by the ratchet wheel 41a and the pawl 42a has a stable one-way rotation characteristic, so that the charging blade 31 can be ensured not to rebound, and the charging blade 31 can be protected. The ratchet mechanism is simple in arrangement mode and working principle, and is more convenient to operate.

As shown in fig. 6-7, in some embodiments of the present invention, the positioning devices 4 may be two and staggered in the up-down direction, the pawl 42a of only one of the positioning devices 4 may be engaged with the corresponding ratchet wheel 41a when the rail vehicle is running, and the two positioning devices 4 may be switched to be engaged when the rail vehicle is running in a reversing direction. Specifically, the charging device 100 may include two positioning devices 4 arranged at intervals in the up-down direction, and each positioning device 4 may include a ratchet wheel 41a and a pawl 42a, where the two ratchet wheels 41a are arranged at intervals in the up-down direction, and the two pawls 42a are arranged at intervals in the up-down direction. For example, when the rail vehicle is traveling in the forward direction, the ratchet wheel 41a located above and the pawl 42a located above engage. When the rail vehicle runs in reverse, the ratchet wheel 41a located below is engaged with the pawl 42a located below. From this, through above-mentioned setting, the blade 31 that charges all can rotate relative coupling assembling 32 when rail vehicle forward travel and backward travel, and positioner 4 all can fix a position the blade 31 that charges to can promote the safety in utilization of charging blade 31, can prevent that the blade 31 that charges from colliding the phenomenon that appears warping and breaking.

In the specific example shown in fig. 4-6, the connection assembly 32 further includes a rotation shaft 325, the rotation shaft 325 is disposed through the charging blade 31 and the connection assembly 32, and the charging blade 31 can rotate relative to the connection assembly 32 through the rotation shaft 325. The first positioning member 41 and the second positioning member 42 are both two, the first positioning member 41 is formed as a ratchet wheel 41a and is disposed on the charging blade 31, and the second positioning member 42 is formed as a pawl 42a and is disposed on the connecting assembly 32. The two ratchet wheels 41a are arranged at intervals in the vertical direction, the upper ratchet wheel 41a includes a first ratchet group 411 and a first escape portion 412, and the lower ratchet wheel 41a includes a second ratchet group 413 and a second escape portion 414.

The first ratchet group 411 is located directly above the second escape portion 414, and the second ratchet group 413 is located directly below the first escape portion 412. When the rail vehicle travels forward, the upper pawl 42a is engaged with the first pawl teeth 411, and the lower pawl 42a can extend into the escape space defined by the second escape portion 414. When the rail vehicle runs in the reverse direction, the lower pawl 42a is engaged with the second pawl group 413, and the upper pawl 42a can extend into the escape space defined by the first escape portion 412. Thus, with the above arrangement, positional interference between the two positioning devices 4 can be prevented, and the rotation of the charging blade 31 can be made smoother.

Alternatively, the first ratchet group 411 and the second ratchet group 413 may each include a plurality of ratchets, and the larger the number of ratchets, the larger the range of rotation angle of the charging blade 31 relative to the connecting assembly 32, and the arrangement may be selected according to actual use requirements, which is not particularly limited by the present invention.

As shown in fig. 5, in some embodiments of the present invention, the connecting assembly 32 may include a connecting rod 321 and a limiting rod 322, the connecting rod 321 may be connected to the vehicle body, the limiting rod 322 may be provided with the second positioning element 42, and the limiting rod 322 may be movably provided on the connecting rod 321 to drive the second positioning element 42 to disengage or cooperate with the first positioning element 41. Specifically, the stopper rod 322 may cooperate with the first positioning member 41 on the charging blade 31 through the second positioning member 42 to restrict the charging blade 31. When the rotation angle of the charging blade 31 with respect to the connecting assembly 32 is too large, the charging blade 31 needs to be reset to improve the charging efficiency. Because the limiting rod 322 is movable relative to the connecting rod 321, the limiting rod 322 can drive the second positioning element 42 to separate from the first positioning element 41, and the positioning device 4 loses the positioning function, so that the inclination angle between the charging blade 31 and the charging panel 1 can be conveniently adjusted. After the charging blade 31 is completely reset, the limiting rod 322 can drive the second positioning element 42 to move to a position matched with the first positioning element 41. Therefore, through the above arrangement, the limiting rod 322 is movable relative to the connecting rod 321, so that the rotation angle of the charging blade 31 can be conveniently adjusted, and the operation of the charging device 100 can be more convenient.

As shown in fig. 5, in some embodiments of the present invention, the connecting assembly 32 may further include a restoring member 323, the restoring member 323 may be respectively abutted against the limiting rod 322 and the connecting rod 321, and the restoring member 323 may be configured to normally drive the limiting rod 322 to move to enable the second positioning member 42 to be engaged with the first positioning member 41, so that the engaging structure between the first positioning member 41 and the second positioning member 42 may be more secure. It is understood that the reset member 323 can apply a driving force to the second positioning member 42 in a direction toward the first positioning member 41, and when the charging blade 31 is subjected to a small impact force, the reset member 323 can prevent the charging blade 31 from rotating relative to the connecting assembly 32. When the impact force applied to the charging blade 31 exceeds the yield limit of the deformation of the charging blade 31, the impact force can overcome the driving force of the reset member 323 to drive the charging blade 31 to rotate relative to the connecting assembly 32, so that the impact force can be buffered, and the charging blade 31 can be prevented from being deformed or broken.

When the interval between the charging pad 1 and the charging blade 31 is too small, the rotating lever 23 may rotate counterclockwise with respect to the first link 21 to move the charging pad 1 upward. When the distance between the charging pad 1 and the charging blade 31 is too large, the rotating lever 23 may rotate clockwise with respect to the first link 21 to move the charging pad 1 downward. Therefore, through the arrangement, the design form of the hinge mechanism 2a is simpler and the operation is smoother.

Alternatively, the rotating rod 23 may be formed as an insulating material, and the first connecting member 21 and the insulating cover plate 5 may be fixedly connected by a fixing member 6, wherein the fixing member 6 may be a bolt. It can be understood that, since the rotating rod 23 is an insulating material, the current in the charging plate 1 can be prevented from being transmitted to the fixing member 6 on the insulating cover plate 5 through the rotating rod 23, and thus the evacuee can be prevented from contacting the fixing member 6 to get an electric shock when escaping.

Alternatively, the rotating rod 23 may be formed as a metal member, the first connecting member 21 and the insulating cover plate 5 may be fixedly connected by the fixing member 6, and the charging device 100 may further include an insulating cover 7, and the insulating cover 7 may be covered on the fixing member 6 on the insulating cover plate 5.

It can be understood that, when the rail vehicle starts to be charged, since the charging blade 31 has a certain running speed, the charging blade 31 will give an upward driving force to the charging plate 1 when contacting the charging plate 1, and the driving member 24 can drive the rotating lever 23 to apply a downward driving force to the charging plate 1, thereby preventing the charging plate 1 from being separated from the charging blade 31.

Alternatively, the driving member 24 may be formed as a torsion spring 24a, the structural design of the torsion spring 24a is simpler, not only is installation convenient, but also the driving force of the torsion spring 24a is larger, and a better driving effect can be achieved.

Therefore, with the above arrangement, the guide section 12 can buffer the impact force between the charging blade 31 and the charging plate 1, and can simultaneously perform the buffer protection function on the charging blade 31 and the charging plate 1.

As shown in fig. 2, in some embodiments of the present invention, the charging plate 1 may further include first flanges 13, the first flanges 13 may be disposed at two ends of the horizontal section 11 in the width direction (perpendicular to the running direction of the charging blade 3) and are bent upward relative to the horizontal section 11, and the first flanges 13 may reinforce the horizontal section 11 and may prevent the horizontal section 11 from being deformed when the impact force is applied thereto.

When the rail vehicle runs in the forward direction, the pawl 42a located above is engaged with the first ratchet group 411, and the pawl 42a located below extends into the second escape portion 414 to define an escape space. When the rail vehicle runs in the reverse direction, the pawl 42a located below is engaged with the second pawl group 413, and the pawl 42a located above extends into the escape space defined by the first escape portion 412.

Specifically, when the rail vehicle enters a station, the charging blade 3 located at the foremost side of the vehicle body is first brought into contact with the charging pad 1 at the rearmost side, and the connecting frame 2 can adjust the position of the charging pad 1 in the vertical direction so that the charging blade 3 is just in contact with the charging pad 1, and the charging blade 31 is slidably engaged with the charging pad 1 and separated from the charging pad 1. Thus, when the rail vehicle travels to the charging position, the plurality of charging blades 31 correspond to the plurality of charging plates 1 one to one and move to the bottom of the corresponding charging plate 1, and the charging blades 31 are electrically connected to the corresponding charging plate 1 to charge the rail vehicle.

The reset member 323 can apply a driving force to the pawl 42a in a direction toward the ratchet wheel 41a, and when the charging blade 31 is subjected to a small impact force, the reset member 323 can prevent the charging blade 31 from rotating relative to the connecting assembly 32. When the impact force applied to the charging blade 31 exceeds the yield limit of the deformation of the charging blade 31, the impact force can overcome the driving force of the reset member 323 to rotate the charging blade 31 relative to the connecting assembly 32, so that the impact force can be buffered, and the charging blade 31 can be prevented from being deformed or broken.

When the rotation angle of the charging blade 31 with respect to the connecting assembly 32 is too large, the charging blade 31 needs to be reset to improve the charging efficiency. Because the limiting rod 322 is movable relative to the connecting rod 321, the adjusting member 324 can be pulled to make the limiting rod 322 drive the pawl 42a to separate from the ratchet 41a, and at this time, the positioning device 4 loses the positioning function, so that the inclination angle between the charging blade 31 and the charging plate 1 can be conveniently adjusted. When the reset of the charging blade 31 is completed, the reset member 323 can drive the pawl 42a to move to a position where it engages with the ratchet wheel 41 a.
