The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A charging slot assembly 100 and a charging device 700 of a railway vehicle and a control method thereof according to an embodiment of the present invention will be described with reference to fig. 1 to 13.

As shown in fig. 1 to 3, according to the charging chute assembly 100 of the embodiment of the present invention, the charging chute assembly 100 includes: the charging device comprises a shell 10, two charging plates 20, a connecting assembly 30 and an air pressure cavity 40.

Specifically, as shown in fig. 1 to 3, the casing 10 includes two spaced-apart protective casings 120. Two charging plates 20 are spaced apart within the housing 10 to define a slot 210. Thus, the case 10 can shield and protect the two charging plates 20. When it is desired to charge the vehicle, the charging blade 710 may extend into the cradle 210 to cooperate with the charging plate 20 to charge the vehicle.

Each charging plate 20 is movably engaged with the corresponding protective case 120 by the connection assembly 30. As shown in fig. 3, the two charging plates 20 are movably connected to the protective case 120 of the housing 10 by the connection assembly 30, respectively, and the two charging plates 20 can be moved toward or away from each other by the connection assembly 30. For example, when the charging blade 710 is inserted into the slot 210, the charging blade 710 presses the two charging plates 20 to move away from each other. This can buffer and absorb the impact of the charging blade 710 on the charging plate 20. When the charging blade 710 is separated from the slot 210, the two charging plates 20 may be restored to the original positions by the connection assembly 30.

As shown in fig. 3, each connecting assembly 30 includes a moving member 320, the moving member 320 is movably engaged with the protective shell 120, a first end of the moving member 320 extends out of the protective shell 120, and a second end of the moving member 320 is connected to the corresponding charging plate 20. Therefore, the moving member 320 can drive the charging plates 20 to move relative to the fixing portion 310 and the housing 10, so that the two charging plates 20 can be driven by the moving member 320 to move toward or away from each other.

At least one air pressure cavity 40 is correspondingly provided for each charging pad 20, that is, each charging pad 20 may be provided with one or more air pressure cavities 40. The air pressure chamber 40 is disposed on the stationary portion and defines an air pressure chamber 410. As shown in fig. 3 and 5, the air pressure chamber 410 has an air pressure control opening 411, and the first end of the moving member 320 is movably located in the air pressure chamber 410. It should be noted that, the air pressure control opening 411 may be used to pump air or inflate the air pressure chamber 410 to adjust the air pressure difference in the air pressure chamber 410, so as to change the pressure difference between the two ends of the moving member 320, and further control the movement of the moving member 320.

For example, when the air pressure chamber 410 is evacuated through the air pressure control port 411, the air pressure difference between the two ends of the moving member 320 drives the moving member 320 to drive the corresponding charging plate 20 to move toward a direction away from the other charging plate 20; when the air pressure chamber 410 is inflated through the air pressure control port 411, the air pressure difference between the two ends of the moving member 320 drives the moving member 320 to drive the corresponding charging plate 20 to move toward the direction close to the other charging plate 20.

As shown in fig. 5, when the air pressure chamber 410 is evacuated through the air pressure control port 411, the evacuation operation may be performed on a part of the air pressure chamber 410, or may be performed on all the air pressure chambers 410. The air pressure in the air pressure chamber 410 is gradually decreased. Under the action of the atmospheric pressure, the atmospheric pressure pushes the charging plate 20 and the moving member 320 to move toward the inside of the atmospheric pressure chamber 410, so that the two charging plates 20 can be moved away from each other. As shown in fig. 6, the gap between the two charging plates 20 is smaller than the thickness of the charging blade 710 before the air pressure chamber 410 is evacuated. When the air pressure chamber 410 is evacuated, the gap between the two charging plates 20 is greater than the thickness of the charging blade 710.

According to the charging slot assembly 100 of the embodiment of the invention, by arranging the air pressure cavity 40, when the vehicle is in a situation of not needing to be charged and rapidly getting over the station, the air pressure chamber 410 can be pumped, and under the action of the atmospheric pressure, the two charging plates 20 move towards the direction away from each other, so that the width of the slot body 210 is larger than that of the charging blade 710. At this time, the charging blade 710 does not contact and collide with the two charging plates 20 when it passes through the slot body 210, thereby reducing the vehicle running noise and improving the service life of the charging device 700 for the vehicle.

According to some embodiments of the invention, as shown in fig. 3, the connection assembly 30 further comprises: the fixing portion 310 is disposed on the corresponding protection shell 120, the moving member 320 is movably engaged with the fixing portion 310, a first end of the moving member 320 extends out of the fixing portion 310, one end of the elastic member 330 is abutted against the protection shell 120 or the fixing portion 310, and the other end of the elastic member 330 is abutted against the charging plate 20. Thus, when the two charging plates 20 move away from each other, the pressing elastic member 330 is elastically deformed, and the elastic member 330 may play a role of buffering. Also, the two charging plates 20 may be driven to move toward each other by the elastic restoring force of the elastic member 330.

In some embodiments of the present invention, the air pressure chamber 40 may be connected with the fixing portion 310; the pneumatic chamber 40 may also be connected to the connection portion 120. The air pressure chamber 410 may be defined solely by the air pressure cavity 40; the air pressure chamber 410 may also be defined by the air pressure cavity 40 and the fixing portion 310; the air pressure chamber 410 may also be defined by the air pressure cavity 40 in combination with the protective shell 120; the air pressure chamber 410 may also be defined by the air pressure chamber 40, the fixing portion 310 and the protective shell 120.

According to some embodiments of the present invention, as shown in fig. 2 to 4, the charging chute assembly 100 further includes a protective cover 50, the protective cover 50 is fixed on an outer sidewall of the protective shell 120, the fixing portion 310 and the moving portion 320 extend into the protective cover 50, an opening is formed on the protective cover 50, the air pressure chamber 40 is formed at the opening to close the opening, and a portion of the air pressure chamber 40 extending into the protective cover 50 is wrapped on the fixing portion 310.

As shown in fig. 4, the shield 50 has an opening through which one end of the air pressure chamber 40 passes and is fitted over the fixing portion 310. The outer peripheral wall of the portion of the air pressure chamber 40 extending into the opening is abutted against the shield 50, and the inner peripheral wall is abutted against the fixing portion 310. Therefore, the firmness and stability of the fixation of the air pressure cavity 40 are improved. Also, the sealability of the air pressure chamber 410 may be improved. In addition, the protection cover 50 can provide good shielding and protecting effects for the connecting component 30.

In some embodiments of the present invention, a portion of the air pressure chamber 40 is in contact with the outer sidewall of the shield 50. As shown in fig. 3 and 4, the portion of the air pressure chamber 40 extending into the shield 50 has an outer diameter smaller than the outer diameter of the exposed portion of the air pressure chamber 40. Thus, the shield 50 may rest on a step surface at the transition of the outer diameter of the pneumatic chamber 40. Thus, the firmness and reliability of the fit between the shield 50 and the air pressure chamber 40 can be improved.

According to some embodiments of the present invention, a seal 510 is provided between the air pressure chamber 40 and the outer sidewall of the shield 50. As shown in fig. 4, a sealing member 510 is provided between the pneumatic chamber 40 and the outer circumferential wall of the shield cap 50 at a step surface where the shield cap 50 is engaged with the pneumatic chamber 40, whereby the sealing property of the pneumatic chamber 410 can be improved. For example, the seal 510 may be a foam or gel, or the like.

In some embodiments of the present invention, as shown in fig. 3 and 4, a connector 412 is disposed at the air pressure control port 411, and the air pressure control device is matched with the connector 412 to pump the air pressure chamber 410. The connection between the pneumatic control device and the pneumatic chamber 40 is facilitated by the provision of the connector 412. For example, the connector 412 may be connected to a pneumatic control device via a conduit to perform a pumping operation on the pneumatic chamber 410.

According to some embodiments of the present invention, the air pressure chamber 40 is provided with an air outlet, which is communicated with the air pressure chamber 410, and has a state of opening or closing the air pressure chamber 410. Thus, when the exhaust port is closed and the air pressure chamber 410 is evacuated by the air pressure control device, the air pressure in the air pressure chamber 410 can be reduced. Under the action of the pressure difference between the two ends, the air pressure pushes the moving member 320 to move towards the air pressure chamber 410, so that the two charging plates 20 move away from each other. When the exhaust port is opened, the external air pressure can enter the air pressure chamber 410 from the exhaust port, and the air pressure difference between the two ends of the moving member 320 is gradually reduced. Under the action of the elastic member 330, the two charging plates 20 can be driven to move toward each other.

According to some embodiments of the present invention, as shown in fig. 3-5, the charging slot assembly 100 further includes a stopper 321, the stopper 321 is disposed on the first end of the moving member 320, and when the moving member 320 moves a set distance, the stopper 321 stops against the fixing portion 310 to limit the moving displacement of the moving member 320. As shown in FIG. 5, the outer diameter of the moving member 320 is smaller than the inner diameter of the fixing portion 310, and the moving member 320 is movably sleeved in the fixing portion 310. The first end of the moving member 320 passes through the fixing portion 310, the end of the first end is provided with a stopper 321, and the stopper 321 extends out of the outer peripheral wall of the moving member 320 along the radial direction of the moving member 320. Therefore, when the moving member 320 moves to a predetermined position, the stopper 321 may abut against the end of the fixing portion 310 to limit the movement of the moving member 320, so that the moving range of the two charging plates 20 may be effectively controlled.

In some embodiments of the present invention, as shown in fig. 3 to 5, an end surface of the limiting block 321 facing the fixing portion 310 is provided with a flexible buffer 322. It should be noted that, when the moving element 320 moves to a predetermined position relative to the fixing element 310, the stopper 321 stops against the fixing element 310 to limit the movement of the moving element 320. Through the arrangement of the flexible buffer 322, the impact between the limiting block 321 and the fixing portion 310 can be buffered and absorbed by the flexible buffer 322, so that the operation noise of the charging slot assembly 100 is reduced, and the operation stability of the charging slot assembly 100 is improved.

It should be noted that at least one of the limiting block 321 and the flexible buffer 322 may abut against the inner circumferential wall of the air pressure cavity 40. That is, the limiting block 321 may abut against the inner peripheral wall of the air pressure cavity 40, or the flexible buffer 322 may abut against the inner peripheral wall of the air pressure cavity 40; of course, the limiting block 321 and the flexible buffer 322 may be both abutted against the inner peripheral wall of the air pressure cavity 40. Therefore, the limiting block 321 and the flexible buffer 322 can seal the air pressure chamber 410, so that the moving member 320 and the air pressure chamber 40 form a piston structure, thereby improving the reliability and stability of the moving member 320 moving in the air pressure chamber 410.

According to some embodiments of the present invention, as shown in fig. 3 to 5, the outer circumferential wall of the fixing portion 310 is provided with a fixing plate 311, and the fixing plate 311 is fixed on the outer circumferential wall of the protective case 120. As shown in fig. 5, the fixing portion 310 may be configured in a cylindrical shape, and the fixing portion 310 has a fixing plate 311 extending in a radial direction on an outer circumferential wall thereof, and a bolt passes through the fixing plate 311 and the protective case 120 to fix the fixing portion 310 to the case 10.

In some embodiments of the present invention, one end of the elastic member 330 is stopped against the fixing plate 311. As shown in fig. 3 and 5, when the two charging plates 20 move in a direction away from each other, the elastic member 330 is pressed and elastically deformed. The elastic member 330 may drive the charging plate 20 to be reset to the initial position by the elastic restoring force of the elastic member 330.

According to some embodiments of the present invention, each charging plate 20 is rotatably provided on the corresponding moving member 320. As shown in fig. 3, the second end of the moving member 320 is connected to the charging plate 20 through a hinge assembly 340, the charging plate 20 is fixed to the hinge assembly 340, and the hinge assembly 340 is rotatably connected to the second section of the moving member 320 through a pin. This allows the charging plate 20 to rotate with respect to the mover 320. For example, when the charging blade 710 collides with the charging plate 20, the charging blade 710 impacts the charging plate 20, and the charging plate 20 can rotate relative to the moving member 320 through the hinge assembly 340 to buffer and absorb the impact of the charging blade 710 on the charging plate 20. Thus, the operation noise of the charging chute assembly 100 can be reduced, and the stability and reliability of the operation of the charging chute assembly 100 are improved.

In some embodiments of the present invention, as shown in fig. 6-9, the end faces of the two protective cases 120 facing each other are provided with a shield 60, the shield 60 is located above the charging board 20, and the shield 60 is a flexible piece. It can be understood that, by arranging the shielding object 60 above the charging panel 20, the shielding object 60 can play a role of shielding and protecting, and can effectively prevent dust and impurities from entering the slot body 210 to affect the charging performance of the charging slot assembly 100, even cause the hidden trouble of short circuit of the charging slot assembly 100, thereby improving the safety and reliability of the charging slot assembly 100. Moreover, the shielding object 60 is a flexible piece, when the charging knife 710 enters the slot body 210, the charging knife 710 can press the shielding object 60, and in the process that the charging knife 710 slides across the slot body 210, the shielding object 60 after the charging knife 710 slides across can be reset to the initial position to shield and protect the slot body 210.

According to some embodiments of the invention, as shown in fig. 8-11, the shroud 60 and the corresponding protective shell 120 are snap-fit. Thus, the fitting connection between the shutter 60 and the protective case 120 is facilitated, and moreover, the removal and replacement of the shutter 60 are facilitated.

As shown in fig. 10, the end of the shield 60 facing the protective shell 120 may be provided with an insertion groove 610, and the end of the protective shell 120 is inserted into the insertion groove 610. As shown in fig. 8 and 9, the shield 60 and the protective shell 120 may be riveted together by rivets. Thus, the firmness and reliability of the assembly between the shutter 60 and the housing 10 can be improved. As shown in fig. 11, a hook 620 may be disposed on the shielding object 60, a slot adapted to the hook 620 is disposed on the protective shell 120, and the shielding object 60 is assembled on the protective shell 120 by the engagement of the hook 620 and the slot. As shown in fig. 12, the blocking object 60 may be provided with an insertion block 630, and the protective shell 120 is provided with an insertion hole adapted to the insertion block 630. The fixed assembly between the shroud 60 and the protective shell 120 is achieved by inserting the inserts 630 into the corresponding receptacles.

In some embodiments of the present invention, each of the protective cases 120 is formed by splicing a plurality of sub-cases 110 along the length direction of the charging pad 20. As shown in fig. 1 and 2, one of the two adjacent sub-housings 110 is provided with a trapezoidal groove 111, and the other is provided with a trapezoidal protrusion 112 matching with the trapezoidal groove 111.
