Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging equipment technology, and in particular to an energy storage charging vehicle with an automatic cable retraction device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the application of energy storage charging vehicles is becoming increasingly widespread. These vehicles integrate energy storage batteries, charging guns, and other components onto autonomous vehicles, enabling them to flexibly provide charging services for new energy vehicles.

[0003] The charging guns of energy storage charging vehicles are typically connected to the energy storage batteries via long and bulky charging cables. These cables are equipped with automatic reel-up devices, which mainly use DC brushless motors, AC asynchronous motors, or open-loop stepper motors. The reel is driven to perform reel-up and unreel-down operations through simple start / stop binary control or manual jogging. This method cannot achieve precise reel-up stop control, and the charging cable may be over-reeled or under-reeled during reel-up, causing damage to the equipment or cables. Summary of the Invention

[0004] The technical problem this invention aims to solve is how to enable precise control of the reel-in and stop of an energy storage charging vehicle.

[0005] To solve the above-mentioned technical problems, the present invention provides an energy storage charging vehicle with an automatic cable retraction device, comprising: The vehicle body contains an energy storage battery. A cable outlet is provided on the vehicle body, and an annular baffle is provided inside the hole; The charging gun cable has one end connected to the energy storage battery and the other end passing through the annular baffle in the outlet hole to the outside of the vehicle body and connecting to the charging gun. An automatic cable retraction device, installed inside the vehicle body, is used to retract the charging gun cable. An annular post is fitted onto the part of the charging gun cable located outside the vehicle body and moves with the charging gun cable. The outer diameter of the annular post is larger than the inner diameter of the annular baffle and smaller than the diameter of the outlet hole. A micro switch, mounted on the annular baffle, is used to detect collisions with the annular post; An industrial control computer is communicatively connected to the automatic take-up device and the micro switch. When it receives a trigger signal from the micro switch, it controls the automatic take-up device to stop the take-up operation.

[0006] Furthermore, the automatic take-up device includes a take-up reel for receiving the charging gun cable and a motor for driving the take-up reel to rotate, and the industrial control computer communicates with the automatic take-up device specifically by communicating with its motor.

[0007] Furthermore, there are two or more micro switches, and the industrial control computer controls the automatic take-up device to stop the take-up operation when it receives a trigger signal from any of the micro switches.

[0008] Furthermore, the industrial control computer is connected to the automatic take-up device via an RS485 bus.

[0009] Furthermore, the contacts of the micro switch face outwards from the vehicle body.

[0010] The present invention has the following beneficial effects: During the automatic take-up device's take-up operation of the charging gun cable, the annular column will move along with the charging gun cable until it collides with the micro switch on the annular baffle. Then, the micro switch sends a trigger signal to the industrial control computer, causing the industrial control computer to control the automatic take-up device to stop the take-up operation, thereby achieving precise take-up stop control and avoiding damage to the equipment or cable caused by over- or under-take-up of the charging gun cable.

[0015] The present invention will be further described in detail below with reference to specific embodiments.

[0016] This embodiment provides an energy storage charging vehicle with an automatic cable retraction device, such as... Figure 1 , Figure 2 and Figure 3As shown, the energy storage charging vehicle includes a vehicle body 1. A cable outlet 2 is located at the front end of the vehicle body 1. An annular baffle 3 is installed inside the cable outlet 2, with its outer ring embedded within the outlet 2 and its inner ring replacing the outlet 2 to form the cable outlet channel. Inside the vehicle body 1 are an energy storage battery (not shown), a charging gun cable 4, and an automatic cable reel 5. One end of the charging gun cable 4 is connected to the energy storage battery, and the other end passes through the annular baffle 3 inside the outlet 2 to the outside of the vehicle body 1 and connects to the charging gun (not shown), thus transmitting power from the energy storage battery to the charging gun. The automatic cable reel 2 is used to unload or reel in the charging gun cable 4. Specifically, it includes a reel for storing the charging gun cable 4 and a brushless DC motor for driving the reel to rotate. The charging gun cable 4 is wound on the reel. When the brushless DC motor rotates forward, it drives the reel to rotate forward to release the charging gun cable 4; when the brushless DC motor rotates in reverse, it drives the reel to rotate in reverse to retract the charging gun cable 4. It should be noted that the forward rotation and reverse rotation described in this embodiment are only used to distinguish between two opposite rotation directions, and do not limit a specific rotation direction.

[0017] The charging cable 4 has an annular post 6, which fits around the part of the charging cable 4 outside the vehicle body 1 and moves with the charging cable 4. The outer diameter of the annular post 6 is larger than the inner diameter of the annular baffle 3 but smaller than the diameter of the outlet hole 2. During the winding process of the charging cable 4, the annular post 6 can move with the charging cable 4 and extend into the outlet hole 2, abutting against the annular baffle 3. Two microswitches 7 are installed on the annular baffle 3, with their contacts facing outward from the vehicle body 1. They are used to detect the collision of the annular post 6 during winding. When the annular post 6 abuts against the annular baffle 3 along with the charging cable 4, it will trigger the microswitches 7 on the annular baffle 3.

[0018] In this embodiment, the vehicle body 1 is also equipped with an industrial control computer (not shown in the figure). This industrial control computer is connected to the DC brushless motor of the automatic take-up device 5 and two microswitches 7 via an RS485 bus. The industrial control computer controls the automatic take-up device 5 to rotate and perform the take-up or put-down operation according to the user's input instructions. During the take-up process, when the annular post 6 follows the charging gun cable 4 and abuts against the annular baffle 3, it will collide and trigger the microswitches 7 on the annular baffle 3. The microswitches 7 send a trigger signal to the industrial control computer. When the industrial control computer receives the trigger signal from the microswitches 7, it sends a stop message to the DC brushless motor of the automatic take-up device 5, controlling the automatic take-up device 5 to stop the take-up operation, thus achieving precise take-up stop control and avoiding damage to the equipment or cable caused by over- or under-take-up of the charging gun cable 4. It should be noted that the microswitches 7 can be set to any number of two or more, as long as each microswitch 7 is triggered independently, so that the industrial control computer controls the automatic take-up device 5 to stop the take-up operation when it receives the trigger signal from any microswitch 7. In addition, the industrial control computer is equipped with an overtime protection function. When the winding time exceeds the preset value (e.g., 10 seconds), it automatically sends a stop message to the DC brushless motor of the automatic winding device 5 to control the automatic winding device 5 to stop the winding operation. The above are merely embodiments of the present invention and are not intended to limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
