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 device 100 for a vehicle and a rail transit system according to an embodiment of the present invention will be described with reference to fig. 1 to 5.
As shown in fig. 1 and 2, according to a charging device 100 of a vehicle according to an embodiment of the present invention, the charging device 100 includes: a tapping spout 10 and a charging blade 20.
Specifically, the intake chute 10 may be provided at the bottom of the vehicle, and the intake chute 10 has a chute body 111 extending in the longitudinal direction. The term "longitudinal" as used herein is to be understood as being parallel to the direction of travel of the vehicle. The tapping spout 10 is electrically connected to the energy storage means of the vehicle. The charging blade 20 is arranged on the track beam 50 of the vehicle, and when the charging blade 20 extends into the trough body 111, the charging blade 20 is electrically connected with the tapping trough 10 to charge the energy storage device.
It should be noted that, by providing the intake chute 10 extending in the longitudinal direction at the bottom of the vehicle, the intake chute 10 can be moved together when the vehicle is running. When the vehicle runs to the charging position, the taking groove 10 moves along with the vehicle, so that the charging blade 20 extends into the groove body 111. The charging knife 20 is connected with a power supply device, and the energy storage device can be charged after the charging knife 20 is electrically connected with the tapping groove 10.
It can be understood that, in the technical solution of disposing the charging blade 20 on the bottom of the vehicle, the charging blade 20 is easy to swing laterally along with the running of the vehicle. The "lateral direction" referred to herein may be understood as a direction perpendicular to the traveling direction of the vehicle. According to the charging device 100 of the vehicle, the tapping chute 10 is arranged at the bottom of the vehicle, and the charging blade 20 is arranged on the track beam 50, so that the problem that the charging blade 20 swings along with the running of the vehicle is effectively avoided, the insertion and matching of the charging blade 20 and the tapping chute 10 are facilitated, and the impact noise of the charging blade 20 and the tapping chute 10 is reduced. The tapping chute 10 can be provided relatively short so as to be adapted to be mounted on the bottom of the vehicle, so that the structure of the tapping chute 10 can be made compact, thereby simplifying the charging device 100 of the vehicle. When the vehicle runs to the charging position, the charging blade 20 can extend into the corresponding groove body 111, so that the charging blade 20 and the flow taking groove 10 are electrically connected to charge the energy storage device, and the charging device is simple in structure, stable and reliable in operation.
According to some embodiments of the invention, as shown in fig. 5, the catch basin 10 comprises: cover body 120 and two charging pieces 110, cover body 120 is the insulating part, and cover body 120 is connected with the vehicle. Therefore, by arranging the cover body 120, the cover body 120 can play a role in shielding and protecting the charging sheet 110, and the potential safety hazards of electric shock and the like caused by mistaken contact of personnel on the charging sheet 110 are effectively avoided.
The two charging sheets 110 are connected to the cover 120 through a connecting member 130, and the two charging sheets 110 are spaced apart from each other to form a slot 111. As shown in fig. 5, the two charging sheets 110 are configured in a plate shape, the two charging sheets 110 extend in a traveling direction of the vehicle, and the two charging sheets 110 are spaced apart to configure a slot 111. Thereby, the fitting between the charging blade 20 and the tapping chute 10 is facilitated. When the vehicle runs to the charging position, the charging blade 20 can conveniently extend into the corresponding flow taking groove 10.
As shown in fig. 5, in some embodiments of the present invention, the connection member 130 includes: an outer cylinder 131, an inner cylinder 132, an elastic member 133, and a hinge assembly 134. Wherein, the outer cylinder 131 is connected with the cover 120. Thus, by providing the outer cylinder 131, the fitting connection between the connector 130 and the cover 120 is facilitated. For example, the outer cylinder 131 and the cover 120 may be screw-fitted. A first end of the inner cylinder 132 is movably received in the outer cylinder 131, and a second end of the inner cylinder 132 is rotatably connected to the charging pad 110 by a hinge assembly 134.
Therefore, the inner cylinder 132 and the outer cylinder 131 can slide relative to each other to drive the corresponding charging sheet 110 to move, and the inner cylinder 132 is rotatably connected to the charging sheet 110 through the hinge assembly 134, so that the charging sheet 110 can rotate relative to the cover 120 to buffer and absorb the impact of the charging blade 20 on the tapping chute 10. The elastic member 133 is sleeved on the inner cylinder 132, one end of the elastic member 133 is positioned on the hinge assembly 134, and the other end of the elastic member 133 is positioned on the outer cylinder 131. Accordingly, the inner cylinder 132 can be driven to return to the original position by the elastic restoring force of the elastic member 133. Also, when the charging blade 20 is inserted into the intake chute 10, the elastic member 133 can absorb the impact of the charging blade 20 on the charging sheet 110.
In some embodiments of the present invention, as shown in FIG. 5, the hinge assembly 134 can be rotatably coupled to the second end of the inner barrel 132 by a pin. Therefore, the connection between the inner cylinder 132 and the hinge assembly 134 is facilitated, and the corresponding charging sheet 110 can rotate in a small range by taking the pin as a rotating shaft, so that the impact of the charging blade 20 on the tapping chute 10 can be buffered and absorbed, the noise can be reduced, and the service life of the tapping chute 10 can be prolonged.
According to some embodiments of the present invention, as shown in fig. 2, the sink 10 may include two charging sheets 110 disposed at intervals, and the two charging sheets 110 may define a trough 111. It should be noted that, as shown in fig. 1 and fig. 2, the bottom of the vehicle may be provided with two taking grooves 10, and the two taking grooves 10 may be respectively connected with the positive pole and the negative pole of the energy storage device. Accordingly, two charging knives 20 may be arranged on the track beam 50, and the two charging knives 20 should be adapted to the two take-up chutes 10 one by one. As shown in fig. 2, each of the intake chutes 10 may include two charging sheets 110 arranged in parallel, and the two charging sheets 110 define a chute body 111. When the tapping chute 10 moves to a charging position along with the vehicle, the charging blade 20 can extend into the corresponding tapping chute 10 to charge the energy storage device.
In some embodiments of the present invention, the charging blade 20 is movable in the lateral direction. It should be noted that the "lateral direction" described herein may be understood as a direction perpendicular to the traveling direction of the vehicle. When the vehicle is driven to the charging position, the tapping chute 10 and the charging blade 20 may not be aligned, for example, there may be a lateral displacement difference between the tapping chute 10 and the charging blade 20. The "lateral direction" referred to herein may be understood as a direction perpendicular to the traveling direction of the vehicle. Therefore, by arranging the charging blade 20 to be movable in a direction perpendicular to the driving direction of the vehicle, when there is a lateral displacement difference between the charging blade 20 and the flow taking groove 10, the flow taking groove 10 and the charging blade 20 can drive the charging blade 20 to move laterally after contacting, so that the charging blade 20 can be adjusted to a position just opposite to the flow taking groove 10, and the charging blade 20 can smoothly slide into the groove body 111. This reduces the impact between the charging blade 20 and the flow collection groove 10, and reduces the impact noise between the charging blade 20 and the flow collection groove 10.
As shown in fig. 2, at both ends of the groove body 111, the ends of the two charging sheets 110 of each of the tapping grooves 10 may be opened in a direction away from each other to form an opening angle of a predetermined angle. Therefore, the end of the charging sheet 110 has a guiding function, so that the charging blade 20 can slide into the groove body 111 conveniently, and the stability and reliability of the operation of the charging device 100 are improved.
According to some embodiments of the present invention, as shown in fig. 3 and 4, the charging blade 20 may include: a base 210, a support arm 220, and a take-off blade 230. Wherein, the base 210 can be fixed on the track beam 50, as shown in fig. 1, the base 210 can be disposed between two track beams 50. The base 210 and the track beam 50 may be connected by welding or bolts.
One end of the supporting arm 220 is slidably connected to the base 210, and as shown in fig. 3 and 4, the lower end of the supporting arm 220 can slide laterally with respect to the base 210. Therefore, when the charging blade 20 is not aligned with the tapping chute 10, the tapping chute 10 can drive the charging blade 20 to move transversely after being contacted with the charging blade 20 along with the running of the vehicle, so that the charging blade 20 can be adjusted to be aligned, and the charging blade 20 can smoothly slide into the tapping chute 10.
The current taking blade 230 is electrically connected with the power supply device, and the current taking blade 230 is fixedly connected with the other end of the supporting arm 220. As shown in fig. 3 and 4, the flow taking blade 230 is fixedly connected to the upper end of the support arm 220. The support arms 220 may be made of an insulating material, for example, the support arms 220 may be made of SMC composite material, which is mainly made of glass fiber reinforced plastic (frp) composed of GF (special yarn), MD (filler) and various additives. The SMC composite material has good corrosion resistance and can prolong the service life of the support arm 220.
According to some embodiments of the present invention, as shown in fig. 3 and 4, the supporting arm 220 may be provided with a buffer 221, and the buffer 221 is located between the flow taking blade 230 and the base 210. It is understood that the vehicle jounces in the up-down direction during traveling. When the vehicle is in different load-bearing states, the distance between the charging blade 20 and the tapping chute 10 in the vertical direction is different. By arranging the buffer member 221 between the flow taking blade 230 and the base 210, the impact of the charging blade 20 and the flow taking groove 10 in the vertical direction can be buffered and absorbed by the buffer member 221, so that the charging blade 20 and the flow taking groove 10 are effectively prevented from being damaged by collision, and the collision noise between the charging blade 20 and the flow taking groove 10 is reduced. The buffer 221 may be a rubber member or a spring.
In some embodiments of the present invention, as shown in fig. 3 and 4, the charging blade 20 may further include: a mounting slider 240, the mounting slider 240 being connected to one end of the supporting arm 220, the mounting slider 240 being slidably connected to the base 210. As shown in fig. 3 and 4, the mounting slider 240 has a fitting groove opened upward, and the lower end of the supporting arm 220 is inserted into the fitting groove and fixedly coupled by a bolt. Of course, the mounting slider 240 may be welded to the lower end of the supporting arm 220. The lower end of the mounting slide 240 is slidably connected to the base 210, whereby the support arm 220 carries the tapping blade 230 in a lateral direction when the mounting slide 240 slides within the base 210.
According to some embodiments of the present invention, one of the base 210 and the mounting slider 240 is provided with at least one guide groove 2110, and the other is provided with at least one guide block 241 adapted to the guide groove 2110. That is, as shown in fig. 3 and 4, a guide groove 2110 may be provided on the base 210, and a guide block 241 adapted to the guide groove 2110 may be provided on the mounting slider 240; of course, the guide block 241 may be provided on the base 210, and the guide groove 2110 adapted to the guide block 241 may be provided on the mounting slider 240. By arranging the guide block 241 and the guide groove 2110, the transverse movement of the charging blade 20 can be realized by the cooperation of the guide block 241 and the guide groove 2110, and the charging blade has a simple structure and is stable in operation.
According to some embodiments of the present invention, there is one guide groove 2110 and one guide block 241. It can be understood that the manufacturing cost of the charging blade 20 can be reduced by providing one guide groove 2110 and one guide block 241 to facilitate the processing and manufacturing of the charging blade 20. Moreover, the guide blocks 2110 and 241 are arranged in one guide groove 2110, so that the guide blocks 241 can be matched with the guide grooves 2110, and the problem that due to the fact that a plurality of guide grooves 2110 and a plurality of guide blocks 241 are arranged, the guide grooves 2110 and the guide blocks 241 are poor in adaptability can be solved.
In some embodiments of the present invention, the guide grooves 2110 and the guide blocks 241 are provided in plural numbers, the plural guide grooves 2110 are matched with the plural guide blocks 241 in a one-to-one correspondence, and the plural guide grooves 2110 and the plural guide blocks 241 are provided at intervals in the longitudinal direction. Therefore, the stability and reliability of the matching between the base 210 and the mounting slide 240 can be improved, and the phenomenon that the charging blade 20 swings back and forth is effectively avoided. As shown in fig. 3 and 4, two guide grooves 2110 may be provided at intervals in the traveling direction of the vehicle on the base 210, and accordingly, two guide blocks 241 adapted to the guide grooves 2110 are provided at the lower end of the mounting slider 240. As shown in fig. 4, the cross section of the guide groove 2110 may be gradually reduced from bottom to top. Accordingly, the cross section of the guide 241 is gradually increased from the top to the bottom. Therefore, the guide block 241 and the guide groove 2110 can be stopped and limited in the vertical direction, so that the guide block 241 is prevented from being separated from the guide groove 2110, and the stability and reliability of the movement of the charging blade 20 are improved.
According to some embodiments of the present invention, the width of the guide groove 2110 is gradually reduced along the bottom wall of the guide groove 2110 to the opening direction of the guide groove 2110. As shown in fig. 3 and 4, the width of the cross section of the guide groove 2110 is gradually reduced in a top-down direction. The guide blocks 241 are configured to be matched with the guide grooves 2110. Therefore, the guide block 241 can be prevented from being separated from the opening of the guide groove 2110, and the firmness and stability of the matching of the guide block 241 and the guide groove 2110 are improved. For example, the cross section of the guide groove 2110 may be trapezoidal, oval, or other shapes.
In some embodiments of the present invention, as shown in fig. 4, stream fetching blade 230 may include: the fixing portion 231 is connected with the support arm 220, the flow guiding portion 232 extends along the traveling direction of the vehicle, and the flow guiding portion 232 is connected with one end, far away from the support arm 220, of the fixing portion 231. As shown in fig. 4, the upper end of the support arm 220 may be provided with a fixing groove, and the flow taking blade 230 has a fixing portion 231 extending downward, and the fixing portion 231 extends into the fixing groove and is fixedly connected thereto by a bolt. Above the fixing portion 231 is a flow guide portion 232 extending in the vehicle traveling direction, and the flow guide portion 232 is formed in a shuttle structure having thin ends and thick middle.
