Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the device comprises a tractor 1, a trailer hinge column 2, a trailer 3, a part to be charged (a battery) 4, a charging area 5, a sensing and positioning device 6, a device deformation power cabin 7 (located below the sensing and positioning device 6 or arranged inside the sensing and positioning device 6), a cross beam 8, a longitudinal beam 9 and a thrust rod 10. The perception positioning equipment 6 is located in the battery replacement platform.
The embodiment of the present application provides a parking positioning auxiliary system for swapping a power platform, as shown in fig. 1, a structural schematic diagram of a parking positioning auxiliary system for swapping a power platform in the embodiment of the present application is provided, and the system includes: the device comprises a resistance device (not shown, including but not limited to a structure formed by a device deformation power cabin 7, a cross beam 8, a longitudinal beam 9 and a thrust rod 10), and a sensing and positioning device 6, wherein the resistance device is connected with the sensing and positioning device 6.
In some embodiments, the resistance device and the sensing and positioning device may be designed integrally or in a split module, which is not specifically limited in the embodiments of the present application.
Before battery replacement, after a vehicle drives into the battery replacement platform and the sensing and positioning device 6 senses that a target wheel reaches a target position, corresponding resistance is provided for the wheel which does not reach the target position through the resistance device, so that the vehicle is braked, and a part to be replaced on the vehicle stops in a battery replacement area 5 of the battery replacement platform.
It should be noted that the "target position" is specifically the target position at which the resistance device begins to extend when the last pair of tractor wheels arrives, and is not the position at which the last pair of tractor wheels is located when the tractor is finally parked. After this position, the resistance device is still moving forward during extension. That is, the "target position" is not the last parking position, but the position that triggers the actuation of the resistance device.
In a specific implementation, the wheel position is sensed through the sensing and positioning device 6 during power change, for example, after it is sensed through the sensing and positioning device 6 (which may be an infrared sensor or a pressure sensor, and is not specifically limited in the embodiment of the present application) that a target wheel has reached the target position, the resistance device is activated to start and provide corresponding resistance to the wheel that has not reached the target position. It should be noted that, since the vehicle and the resistance device will move relatively at this time, when the speeds of the vehicle and the resistance device need to satisfy a certain condition, the resistance device can provide corresponding resistance to the wheel which does not reach the target position, and finally the vehicle is braked and the part to be charged on the vehicle stops in the charging area 5 of the charging platform, as shown in fig. 4.
It can be understood that both braking and stopping are required and the part to be charged needs to be stopped in the charging area 5 of the charging platform.
Further, excessive forward travel of the vehicle is prevented by the resistance device providing a corresponding resistance to the wheel not reaching the target position. Then the vehicle is braked, and a part to be charged on the vehicle stops in a charging area 5 of the charging platform.
Preferably, the tractor-trailer which is required to be switched before the vehicle is braked and the part to be switched on the vehicle stops at the power switching area of the power switching platform is switched on the power switching platform from the entrance slope of the power switching platform in an automatic driving or manual driving mode, and the tractor-trailer is already straight before the entrance slope of the power switching platform is switched on. I.e. no extra driving operations such as reversing, position selection etc. are required.
Preferably, the sensing and positioning equipment is arranged in the battery replacement platform, and the resistance equipment is in communication connection with the sensing and positioning equipment. It will be appreciated that the resistance device may apply a resistance to the vehicle in dependence upon the sensing of the location-sensing device. Meanwhile, the perception positioning device is hidden (can be arranged in the battery replacement platform through a transparent partition plate or in other modes).

As an alternative embodiment, when determining the target wheel, a pair of wheels at the end of the tractor is used as a reference object for determining the target position, that is, the sensing and positioning device 6 senses that the target wheel has reached the target position during the process of driving the vehicle into the battery replacement platform. When a pair of wheels at the tail end of the tractor reaches a target position, the system judges that the resistance equipment needs to be started.
It can be understood that if it can be determined in advance that the tractor needing to be subjected to battery replacement has several shafts, the geometric relationship between the several shafts of the tractor needing to be subjected to battery replacement can be known in advance. That is to say no matter which axle is perceived, as long as through the geometrical relation between tractor trailer and the trade electric platform, confirm that certain benchmark that satisfies the tractor is discerned, as the signal that resistance equipment opened, and the opening speed of resistance equipment and the speed of traveling of vehicle satisfy the faster requirement of the former, all belong to the scope of protection of this application.
