Description

Technical Field

[0001] The present invention belongs to the technical field of electric vehicle charging, and specifically relates to a mobile charging system for electric vehicles. Background Art

[0002] At present, the new energy vehicles in China are mainly pure electric vehicles and hybrid electric vehicles. The charging problems of these two types of vehicles have always been obstacles to the development of new energy vehicles. Currently, the charging of new energy vehicles mainly relies on charging piles. However, the current battery technology determines that there are great limitations in charging duration, cruising range, etc. when using charging piles for charging; another charging method by replacing the battery pack also cannot be widely promoted due to problems such as cost and occupied space. Summary of the Invention

[0003] In order to overcome the problems faced by the existing electric vehicle charging technology, the present invention discloses a mobile charging system for electric vehicles. The present invention can not only effectively alleviate the problems faced by the existing electric vehicle charging, but also greatly reduce the number of in-vehicle battery packs, effectively reduce the vehicle weight, and greatly improve the vehicle load.

[0004] The technical solution of the described mobile charging system for electric vehicles consists of a control system, a current stabilizing rectifier, a telescopic conductive rod, and a long-distance road slot power supply system. Its structural features are as follows: The mobile charging system for electric vehicles can select any pure electric vehicle or hybrid electric vehicle. A rear-mounted battery pack is provided inside the electric vehicle or hybrid electric vehicle, and a control system is set at the instrument panel of the front cab. The control system is built-in with an intelligent control module, a network module, and an intelligent electricity meter billing module. The intelligent control module has an intelligent recognition function. It intelligently recognizes and locates through a camera at the rear of the vehicle, controls the telescopic and steering of the telescopic conductive rod, so that the contactor at the end of the telescopic rod accurately contacts the intelligent switch in the long-distance road slot power supply system; the network module and the intelligent electricity meter billing module support IC cards or mobile payments, and integrate payment methods such as ETC.

[0005] The electric vehicle or hybrid electric vehicle is provided with a telescopic conductive rod. The telescopic conductive rod is arranged on a universal joint at the rear of the vehicle, is of a hollow structure, usually hidden inside the vehicle, and can be telescopically rotated under the control of the control system. One end of the charging wire and the control wire is connected to the contactor, and the other end is connected to the voltage stabilizing and rectifying device through a winding shaft.

[0006] The long-distance trough-type power supply system is constructed by digging a trough at the outermost marking line of the motor vehicle lane on the road surface, setting up a roller conveyor belt in the trough, laying a conductive cable on the conveyor belt and connecting it to the transmission cable, installing intelligent switches at certain intervals on the conductive cable for receiving vehicle information and controlling charging and powering off, installing four horizontal shifting blocks on the edge of the conveyor belt for shifting the roller shaft to control the reciprocating motion of the transmission cable, laying the charging cable under the conveyor belt and bypassing the roller shaft, and installing a push rod at the end and middle of the conveyor belt on both sides of the roller shaft, and laying a pipeline leading to the outside of the road every 400-500 meters for connecting to the city power to supply power to the transmission cable, while also having a drainage function.

[0007] The intelligent switch is connected to the charging line and control line of the vehicle contactor respectively. The switch has a built-in authentication system and controls the charging and disconnection of the vehicle by receiving authentication information from the vehicle control system.

[0008] The lateral shifting blocks are installed with four shifting blocks at equal distances in the direction of the wire rolling shaft on the conveyor belt, and are used to shift the wire rolling shaft so that it pushes the charging cable to move.

[0009] The rolling shaft and the rolling shaft stator are cross bars that can slide left and right. The charging cable passes around the rolling shaft rotor and is connected to the conductive cable. When the charging cable moves under the conveyor belt, the rolling shaft stator rolls forward under the push of the horizontal shift block, pushing the charging cable forward. When the charging cable moves above the conveyor belt, it drives the rolling shaft to roll backward.

[0010] The push rod is characterized in that: the two push rods are respectively installed at the end and the middle position of the conveyor belt, the push rod at the end position is flush with the side of the roller stator close to the conveyor belt, and the push rod at the middle position is flush with the side of the roller stator close to the groove wall. When the roller pushes the cable to the end of the conveyor belt, the push rod triggers the switch on the roller stator to retract it to avoid contact with the shift block during the return journey. When the cable drives the roller back to the middle position of the conveyor belt, the push rod activates the switch on the roller stator to make it pop out and contact with the shift block.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1 , the technical solution of the mobile charging system for the electric vehicle consists of a control system, a steady current rectifier, a telescopic conductive rod, and a long-distance trough power supply system on the road surface.

[0018] Please refer to Figure 4 , the control system is built-in with an intelligent control module, a network module, and an intelligent electricity meter billing module. The intelligent control module has an intelligent recognition function. It intelligently recognizes and locates through a camera at the rear of the vehicle, controls the telescopic rotation of the telescopic conductive rod and the clamping and releasing of the elastic clamp, so that the contactor accurately contacts or disengages from the intelligent switch in the long-distance trough power supply system on the road surface to realize power reception and disconnection; the network module and the intelligent electricity meter billing module can support IC cards or mobile payments, and integrate payment methods such as ETC.

[0019] Please refer to Figure 1 , Figure 2 , Figure 4 , the electric vehicle or hybrid vehicle is provided with a telescopic conductive rod. The telescopic conductive rod is arranged on the universal joint at the rear of the vehicle and is of a hollow structure. Usually, it is hidden in the vehicle and can be telescopically rotated under the control of the control system. One end of the charging wire and the control wire passes through the internal cavity of the rod and is connected to the contactor, and the other end is connected to the voltage stabilizing and rectifying device.

[0020] Please refer to Figure 2 , Figure 3When the car needs to be charged, the control system controls the retractable conductive rod to extend, so that the contactor contacts the intelligent switch on the conductive cable of the conveyor belt, and pulls the conveyor belt forward at the same time. The intelligent switch receives the vehicle authentication information transmitted by the control line on the contactor and connects the charging. When the transmission moves to the end, the contactor and the intelligent switch automatically disengage. When the charging cable is on the conveyor belt, the charging cable pulls the roller shaft to roll in the middle of the conveyor belt. When the charging cable moves to the bottom of the conveyor belt, the roller shaft is located in the middle of the conveyor belt. The push rod triggers the stator switch of the roller shaft, causing the stator to pop out inward, and the charging cable is driven to move to the end of the conveyor belt under the push of the shift block. When the roller shaft moves to the end of the conveyor belt, the charging cable has moved to the top of the conveyor belt. The push rod triggers the stator switch of the roller shaft, causing the stator to pop outward to prevent the shift block from blocking the return of the roller shaft, so that the charging cable can reciprocate normally.

[0021] See also Figure 4 At the outermost marking line of the motor vehicle lane on the road, a trench is dug, and a roller conveyor belt is set up in the trench. A conductive cable is laid on the conveyor belt and connected to the transmission cable. Intelligent switches are installed at a certain interval on the conductive cable to receive vehicle information and control charging and power off. Four horizontal shift blocks are installed on the edge of the conveyor belt to shift the roller shaft to control the reciprocating motion of the transmission cable. The charging cable is laid under the conveyor belt and bypasses the roller shaft, and a push rod is installed at the end and middle of the conveyor belt on both sides of the roller shaft. A pipeline leading to the outside of the road is laid every 400-500 meters to connect to the city power to power the transmission cable, and it also has a drainage function.

[0022] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
