Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

In the embodiment of the vehicle with the vehicle-mounted bus device of the invention, as shown in fig. 3 to 7, the vehicle comprises a vehicle body 28, the vehicle-mounted bus device 27 is mounted on the top of the vehicle body 28, the vehicle-mounted bus device 27 comprises a base mounted on the top of the vehicle body 28, the base comprises a fixed base below and a rotary table 14 rotatably mounted on the fixed base, the fixed base comprises a base support 13, the base support 13 is fixedly mounted on the vehicle body through an insulator 11, a fixed disc 12 is fixedly mounted on the base support 13, and the rotary table 14 is rotatably mounted on the fixed disc 12 through a bearing structure.

The rotating platform 14 is fixedly provided with a pole plate mounting frame 20, the pole plate mounting frame 20 is provided with four vehicle-mounted pole plates 18, as can be seen from fig. 4, the four vehicle-mounted pole plates 18 extend along the front-back direction, and are divided into two vehicle-mounted pole plate groups arranged at intervals left and right, and each vehicle-mounted pole plate group comprises two vehicle-mounted pole plates 18 arranged at intervals along the front-back direction. As can be seen from fig. 4 and 5, a guide rail 22 extending in the front-rear direction is disposed on the pole plate mounting frame 20 corresponding to each vehicle-mounted pole plate 18, an insulating support 30 is fixedly disposed below the vehicle-mounted pole plate 18, a slider 31 is fixed at the bottom of the insulating support 30, and the front-rear movement of the vehicle-mounted pole plate 18 can be guided by the cooperation between the slider 31 and the guide rail 22. In this embodiment, the distance between two on-vehicle polar plates 18 in the same on-vehicle polar plate group is adjustable.

As shown in fig. 7, the housing 21 is fixedly attached to the turntable 14, the fixing plate 34 is provided in the housing 21, the turntable rotating motor 33 is fixedly attached to the fixing plate 34, and the motor case of the turntable rotating motor 33 is fixed to the fixing plate 34. The turntable 14 is provided with a through hole with a diameter larger than the outer diameter of the output rotating shaft of the turntable rotating motor 33, and the output rotating shaft of the turntable rotating motor 33 passes through the turntable 14 and is fixedly assembled with the fixed disc 12. When the rotating platform rotating motor 33 rotates, the motor shell of the rotating platform rotating motor 33 drives the rotating platform 14 to rotate, so that the vehicle-mounted polar plate 18 on the rotating platform 14 is perpendicular to the extension direction of the pantograph polar plate of the pantograph 26 on the charging pile 25, and the purpose of accurate butt-joint charging is achieved.

In the present embodiment, although the rotation of the turntable 14 makes it possible to make the on-vehicle pole plate 18 perpendicular to the extending direction of the pantograph pole plate in the pantograph 26, the on-vehicle pole plate 18 does not necessarily correspond to the pantograph pole plate in the butting direction, and the distance between two on-vehicle pole plates 18 in the same on-vehicle pole plate group does not meet the requirement of the butting charging. At this time, the distance between two on-board pole plates 18 in the same on-board pole plate group needs to be adjusted, for this reason, racks 23 are fixedly mounted on the insulating supports 30 below the on-board pole plates 18, the turntable 14 is provided with two driving motors 19, and the two driving motors 19 correspond to the respective on-board pole plate groups. A gear is rotatably arranged on an output rotating shaft of the driving motor 19, the gear is meshed with the rack 23, and the vehicle-mounted pole plate 18 can be driven to move back and forth through the driving motor 19. In this embodiment, the racks 23 on the two vehicle-mounted polar plates 18 in the same vehicle-mounted polar plate group are respectively located on the upper and lower sides of the corresponding gear and are all meshed with the gear, so that the two vehicle-mounted polar plates 18 can be driven to move relatively by the driving motor 19, and thus, the number of the driving motors 19 is saved, and the consistency of the position adjustment of the two vehicle-mounted polar plates 18 in the same vehicle-mounted polar plate group is ensured.

In practical use, the vehicle-mounted converging device 27 is exposed in the air, dust or other impurities inevitably fall on the upper end face (i.e., the charging butt joint face) of the vehicle-mounted polar plate 18, and if the impurities are not cleaned in time, the vehicle-mounted polar plate 18 cannot be in good contact with the pantograph 26 for conducting electricity, or even if the impurities can be in contact for conducting electricity, the impurities are easy to spontaneously combust in a high-temperature environment, so that safety accidents are easy to happen.

In order to solve the above problem, as shown in fig. 7, a cleaning brush rotating motor 32 is fixedly mounted in the housing 21, a motor housing of the cleaning brush rotating motor 32 is fixedly mounted on a fixing plate 34, an output rotating shaft of the cleaning brush rotating motor 32 penetrates through the housing 21, and a mounting plate 17 is mounted on the output rotating shaft. As shown in fig. 5 and 6, the mounting plate 17 is provided with a cleaning brush, the cleaning brush includes two cleaning brush supports 16 uniformly distributed on the mounting plate 17 along the circumferential direction, and the cleaning brush supports 16 are respectively provided with bristles 15. The lower ends of the bristles 15 are positioned on the upper end face of the vehicle-mounted polar plate 18, and the vehicle-mounted polar plate 18 can be cleaned in the rotating process. As can be seen from fig. 6, the axis of rotation of the sweeper brush is located at the center of the base, and the four vehicle-mounted pole plates 18 are circumferentially spaced around the mounting plate 17, so that the two sweeper brush supports 16 and the brush bristles 15 can be driven to rotate for sweeping through the rotation of the mounting plate 17.

The turntable 14 is further provided with a control box 24, and when the control box 24 rotates, the control box 24 rotates together with the turntable 14 and the motors, and the control box 24 is actually a motor controller and can control start and stop of the driving motor 19, the sweeping brush rotating motor 32 and the turntable rotating motor 33. The control box 24 is connected with a control device 29 on the vehicle instrument desk in a control mode, and the control device 29 controls the starting and stopping of each motor through the control box 24. Specifically, the control device 29 and the control box 24 are in the signal control mode.

The using process of the invention is as follows: when the vehicle needs to be charged, the driver stops the vehicle under the charging pile 25 with the pantograph 26 mounted thereon, and aligns or maintains the center of the on-vehicle bus device 27 with the center of the pantograph 26 within a certain deviation range.

If the extending directions of the vehicle-mounted polar plates 18 and the pantograph polar plates in the vehicle-mounted converging device 27 are vertical and the polar plate intervals are consistent, controlling the cleaning brush rotating motor 32 to drive the cleaning brush to rotate so as to clean the sundries on the vehicle-mounted polar plates 18, and triggering the pantograph 26 to fall to contact with the vehicle-mounted polar plates 18 of the vehicle-mounted converging device 27 for charging after cleaning;

if the extending directions of the vehicle-mounted polar plates 18 and the pantograph polar plates in the vehicle-mounted converging device 27 are vertical but do not correspond to each other in the vertical direction (i.e. the distance between two vehicle-mounted polar plates 18 in the same vehicle-mounted polar plate group is not consistent with the distance between two corresponding pantograph polar plates), the driving motor 19 is controlled to drive the corresponding vehicle-mounted polar plates 18 to move and adjust, so that the distance between two vehicle-mounted polar plates 18 is consistent with the distance between two pantograph polar plates in the pantograph 26, and then the polar plates are cleaned and charged.

If the distance between the vehicle-mounted plates 18 in the vehicle-mounted collecting device 27 is consistent with the distance between the pantograph plates, but the extending direction of the vehicle-mounted plates 18 is parallel to the extending direction of the pantograph plates, the operation control device 29 controls the rotary table rotating motor 33 in the vehicle-mounted collecting device 27 to be started, drives the rotary table 14 to rotate, enables the extending directions of the vehicle-mounted plates 18 in the vehicle-mounted collecting device 27 and the pantograph plates to be perpendicular and enables the positive and negative electrodes to correspond to each other, and then performs plate cleaning and charging operations.

If the extending direction of the vehicle-mounted polar plates 18 in the vehicle-mounted converging device 27 is parallel to the extending direction of the pantograph polar plates and the distance between the vehicle-mounted polar plates 18 is inconsistent, the operation control device 29 controls the rotary table rotating motor 33 in the vehicle-mounted converging device 27 to be started to drive the rotary table 14 to rotate, so that the vehicle-mounted polar plates 18 in the vehicle-mounted converging device 27 are perpendicular to the extending direction of the pantograph polar plates and the positive and negative poles of the vehicle-mounted polar plates correspond to each other, then controls the driving motor 19 to drive the corresponding vehicle-mounted polar plates 18 to move and adjust, and finally performs polar plate.

In this embodiment, the driving motor 19, the gear and the rack 23 constitute a movement driving mechanism, and the movement driving mechanism is used to drive the corresponding vehicle-mounted pole plate 18 to perform horizontal linear movement adjustment, and it should be noted that, for the purpose of horizontal movement adjustment of the vehicle-mounted pole plate 18, a mechanism capable of outputting a linear force, such as a hydraulic cylinder, a pneumatic cylinder, an electromagnetic push rod, an electric push rod, and the like, may be used to replace the driving motor 19, the gear and the rack 23. Alternatively, if cost is not a concern, a movement driving mechanism may be provided for each of the on-vehicle pole plates 18.

In the embodiment, the vehicle-mounted pole plate 18 is linearly and reciprocally movably assembled on the pole plate mounting frame 20 through the insulating support 30, the sliding block 31 and the guide rail 22, and in other embodiments, the insulating support and the sliding block may be an integrated structure; or, because the output action of the mobile driving mechanism is a linear output action, in other embodiments, the guide rail can be eliminated, and only the vehicle-mounted polar plate is placed on the polar plate mounting frame, and because the safety problem is involved, the insulating support still needs to be arranged below the vehicle-mounted polar plate.

In this embodiment, the cleaning brush rotating motor 32 constitutes a cleaning driving mechanism, and the cleaning brush is rotatably disposed on the base, while in other embodiments, the cleaning brush is linearly and reciprocally disposed on the base, and the above-mentioned moving driving mechanism can be adopted as the corresponding cleaning driving mechanism.
