Description

Vehicle with on-board merging device

Technical Field

The invention relates to a vehicle with an on-vehicle merging device.

Background Art

With the popularization and promotion of new energy vehicles by the country and the market's demand for rapid vehicle charging, high-current fast charging interfaces have become an industry development trend. With the continuous expansion of charging interfaces, charging automation, intelligence and diversity have become product highlights of automakers. The development of diversified charging interfaces has also caused incompatibility among charging interfaces of different automakers.

The existing charging system of electric vehicles is shown in FIG1, which includes a charging pile fixed on the ground, the charging pile includes a column 1 and a pantograph 3 correspondingly suspended and assembled through a telescopic frame 2, and the charging system also includes a vehicle-mounted merging device 4 fixedly mounted on the top of the vehicle body 5. The structure of the vehicle-mounted merging device is shown in FIG2, which includes a base, the base includes a base bracket 10 fixedly mounted on the vehicle body 5 through an insulator 9, and a plate mounting frame 7 is fixedly mounted on the base bracket 10 through a supporting column 8. The plate mounting frame 7 is fixedly provided with a vehicle-mounted plate 6, and the vehicle-mounted plate 6 is used to communicate with the pantograph plate on the pantograph to realize the charging operation. This type of charging system is relatively common, such as the charging system disclosed in the Chinese utility model patent with the authorization announcement number CN207311147U, which is the above-mentioned type.

In fact, from the current market research, the differences between the on-board convergence devices produced by different car companies are mainly concentrated in the length of the on-board plates, the direction and position of the plates relative to the vehicle body. There are large differences in the length, direction and position of the on-board plates of different vehicles, and the corresponding pantographs on the ground charging piles also have their own characteristics. The on-board convergence device fixed on the vehicle body is not easy to dock and charge on the pantographs of other car companies. For example, if the on-board plates in the on-board convergence device and the pantograph plates on the pantograph cannot correspond in the direction of the interval docking (generally the up and down direction), they cannot be accurately docked and charged. The diversity of on-board convergence devices and ground charging piles makes it inconvenient to charge electric vehicles, limiting the popularization and promotion of electric vehicles in the market.

DETAILED DESCRIPTION

The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

A specific embodiment of a vehicle with an on-board convergence device of the present invention is shown in Figures 3 to 7. The vehicle includes a vehicle body 28, and an on-board convergence device 27 is installed on the top of the vehicle body 28. The on-board convergence device 27 includes a base installed on the top of the vehicle body 28, and the base includes a fixed base below and a turntable 14 rotatably installed on the fixed base. The fixed base includes a base bracket 13, and the base bracket 13 is fixedly installed on the vehicle body through an insulator 11. A fixed plate 12 is fixedly installed on the base bracket 13, and a turntable 14 is rotatably installed on the fixed plate 12 through a bearing structure.

A plate mounting frame 20 is fixedly mounted on the turntable 14, and four vehicle-mounted plates 18 are mounted on the plate mounting frame 20. As can be seen from FIG4, the four vehicle-mounted plates 18 extend in the front-to-back direction and are divided into two vehicle-mounted plate groups arranged at intervals on the left and right. Each vehicle-mounted plate group includes two vehicle-mounted plates 18 arranged at intervals in the front-to-back direction. As can be seen from FIG4 and FIG5, a guide rail 22 extending in the front-to-back direction is provided on the plate mounting frame 20 corresponding to each vehicle-mounted plate 18, and an insulating bracket 30 is fixed below the vehicle-mounted plate 18. A slider 31 is fixed at the bottom of the insulating bracket 30, and the front-to-back movement of the vehicle-mounted plate 18 can be guided by the cooperation between the slider 31 and the guide rail 22. In this embodiment, the spacing between two vehicle-mounted plates 18 in the same vehicle-mounted plate group is adjustable.

As shown in FIG7 , a housing 21 is fixedly mounted on the turntable 14, a fixing plate 34 is provided inside the housing 21, a turntable rotating motor 33 is fixedly mounted on the fixing plate 34, and the motor housing of the turntable rotating motor 33 is fixed on the fixing plate 34. A through hole with a hole diameter larger than the outer diameter of the output shaft of the turntable rotating motor 33 is provided on the turntable 14, and the output shaft of the turntable rotating motor 33 passes through the turntable 14 and is fixedly assembled with the fixing plate 12. When the turntable rotating motor 33 rotates, the motor housing of the turntable rotating motor 33 drives the turntable 14 to rotate, so that the vehicle-mounted plate 18 on the turntable 14 is perpendicular to the extension direction of the pantograph plate of the pantograph 26 on the charging pile 25, so as to achieve the purpose of accurate docking and charging.

In this embodiment, although the rotation of the turntable 14 can realize that the vehicle-mounted plate 18 is perpendicular to the extension direction of the pantograph plate in the pantograph 26, the vehicle-mounted plate 18 may not correspond to the pantograph plate in the docking direction, and the distance between the two vehicle-mounted plates 18 in the same vehicle-mounted plate group does not meet the requirements of docking charging. At this time, it is necessary to adjust the distance between the two vehicle-mounted plates 18 in the same vehicle-mounted plate group. For this purpose, a rack 23 is fixedly installed on the insulating bracket 30 under each vehicle-mounted plate 18, and a drive motor 19 is arranged on the turntable 14. The number of the drive motors 19 is two, and the two drive motors 19 correspond to their respective vehicle-mounted plate groups. A gear is fixedly installed on the output shaft of the drive motor 19, and the gear is meshed with the rack 23. The vehicle-mounted plate 18 can be driven to move forward and backward through the drive motor 19. In this embodiment, the racks 23 on the two vehicle-mounted pole plates 18 in the same vehicle-mounted pole plate group are respectively located on the upper and lower sides of the corresponding gears and are meshed with the gears. Thus, the two vehicle-mounted pole plates 18 can be driven to move relative to each other through the driving motor 19. This not only saves the number of driving motors 19, but also helps to ensure the consistency of the position adjustment of the two vehicle-mounted pole plates 18 in the same vehicle-mounted pole plate group.

During actual use, the on-board convergence device 27 is exposed to the air, and dust or other debris will inevitably fall on the upper end surface of the on-board electrode 18 (i.e., the charging docking surface). If the debris is not cleaned up in time, the on-board electrode 18 will not be able to make good contact with the pantograph 26 for conductivity, or even if they can make good contact for conductivity, the debris is prone to spontaneous combustion in a high temperature environment, which may easily lead to safety accidents.

To solve the above problems, as shown in FIG7 , a cleaning brush rotating motor 32 is also fixedly installed in the housing 21, and the motor housing of the cleaning brush rotating motor 32 is fixedly installed on the fixing plate 34, and the output shaft of the cleaning brush rotating motor 32 passes through the housing 21, and a mounting plate 17 is installed on the output shaft. As shown in FIG5 and FIG6 , a cleaning brush is installed on the mounting plate 17, and the cleaning brush includes two cleaning brush brackets 16 uniformly distributed on the mounting plate 17 along the circumferential direction, and bristles 15 are respectively arranged on each cleaning brush bracket 16. The lower end of the bristle 15 is located at the upper end face of the vehicle-mounted electrode plate 18, and the vehicle-mounted electrode plate 18 can be cleaned during the rotation process. As can be seen from FIG6 , the rotation axis of the cleaning brush is located at the center of the base, and the four vehicle-mounted electrode plates 18 are arranged circumferentially around the mounting plate 17, so that the rotation of the mounting plate 17 can drive the two cleaning brush brackets 16 and the bristles 15 to rotate and clean.

A control box 24 is also provided on the turntable 14. When the turntable 14 rotates, the control box 24 rotates together with the turntable 14 and each motor. The control box 24 is actually a motor controller, which can control the start and stop of the drive motor 19, the cleaning brush rotating motor 32 and the turntable rotating motor 33. The control box 24 is connected to the control device 29 on the vehicle instrument panel, and the control device 29 controls the start and stop of each motor through the control box 24. Specifically, the control device 29 and the control box 24 are in a signal control mode.

The use process of the present invention is as follows: when the vehicle needs to be charged, the driver parks the vehicle under the charging pile 25 equipped with the pantograph 26, and aligns the center of the on-board merging device 27 with the center of the pantograph 26 or keeps them within a certain deviation range.

If the vehicle-mounted plate 18 and the pantograph plate in the vehicle-mounted merging device 27 extend in a perpendicular direction and the distance between the plates is consistent, the cleaning brush rotating motor 32 is controlled to drive the cleaning brush to rotate to clean the debris on the vehicle-mounted plate 18. After the cleaning is completed, the pantograph 26 is triggered to descend and contact the vehicle-mounted plate 18 of the vehicle-mounted merging device 27 for charging;

If the extension directions of the vehicle-mounted pole plate 18 and the pantograph pole plate in the vehicle-mounted convergence device 27 are perpendicular but do not correspond in the up and down directions (that is, the spacing between the two vehicle-mounted pole plates 18 in the same vehicle-mounted pole plate group is inconsistent with the spacing between the corresponding two pantograph pole plates), the control drive motor 19 drives the corresponding vehicle-mounted pole plate 18 to move and adjust so that the spacing between the two vehicle-mounted pole plates 18 is consistent with the spacing between the two pantograph pole plates in the pantograph 26, and then the plate cleaning and charging operations are performed.

If the spacing between the on-board plates 18 in the on-board convergence device 27 is consistent with the spacing between the pantograph plates, but the extension direction of the on-board plates 18 is parallel to the extension direction of the pantograph plates, the operation control device 29 controls the turntable rotating motor 33 in the on-board convergence device 27 to start, driving the turntable 14 to rotate, so that the on-board plates 18 in the on-board convergence device 27 are perpendicular to the extension direction of the pantograph plates and the positive and negative poles correspond, and then the plate cleaning and charging operations are performed.

If the extension direction of the vehicle-mounted plate 18 in the vehicle-mounted convergence device 27 is parallel to the extension direction of the pantograph plate, and the spacing between the vehicle-mounted plates 18 is also inconsistent, the operation control device 29 controls the turntable rotation motor 33 in the vehicle-mounted convergence device 27 to turn on, driving the turntable 14 to rotate, so that the extension directions of the vehicle-mounted plate 18 and the pantograph plate in the vehicle-mounted convergence device 27 are perpendicular and the positive and negative poles correspond, and then controls the drive motor 19 to drive the corresponding vehicle-mounted plate 18 to move and adjust, and finally performs the plate cleaning and charging operations.

In this embodiment, the driving motor 19, the gear and the rack 23 constitute a mobile driving mechanism, and the function of the mobile driving mechanism is to drive the corresponding vehicle-mounted plate 18 to perform horizontal linear movement adjustment. It should be noted that in order to achieve the purpose of horizontal movement adjustment of the vehicle-mounted plate 18, a mechanism with linear output such as a hydraulic cylinder, a pneumatic cylinder, an electromagnetic push rod, an electric push rod, etc. can be selected to replace the driving motor 19, the gear and the rack 23. Alternatively, if the cost issue is not considered, a mobile driving mechanism can be equipped for each vehicle-mounted plate 18.

In this embodiment, the vehicle-mounted plate 18 is assembled on the plate mounting frame 20 so as to be linearly movable and reciprocating through the insulating bracket 30, the slider 31 and the guide rail 22. In other embodiments, the insulating bracket and the slider can be an integrated structure; or, since the output action of the mobile drive mechanism is a linear output action, in other embodiments, the guide rail can be eliminated and only the vehicle-mounted plate can be placed on the plate mounting frame. Due to safety issues, an insulating bracket still needs to be provided under the vehicle-mounted plate.

In this embodiment, the cleaning brush rotating motor 32 constitutes a cleaning drive mechanism, and the cleaning brush is rotatably arranged on the base. In other embodiments, the cleaning brush can be arranged on the base in a linear reciprocating manner, and the corresponding cleaning drive mechanism can adopt the above-mentioned mobile drive mechanism. In this embodiment, the control box 24 constitutes a motor controller.
