Description

Technical Field

[0001] The utility model relates to the technical field of charging pile protection, in particular to an automatic wire-retracting charging pile. Background Art

[0002] Currently, a charging pile is a charging device that provides power for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in public buildings and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current. Due to the high value of charging piles, protection and optimization of charging piles is necessary.

[0003] For example, a Chinese utility model patent with announcement number CN215904339U discloses a new energy vehicle charging pile that prevents electric shock. Although the above-mentioned prior art is provided with a series of structures to prevent users from getting electric shock when using the device, when the charging pile is finished using, some people will simply unplug the charging cable and leave it alone for the sake of saving trouble. This will cause the charging cable to fall to the ground, which will not only affect the subsequent use of the vehicle, but even some of the charging cables on the ground will be crushed by the car and damaged. Therefore, it is necessary to design a charging pile that can automatically retract the cable. Utility Model Content

[0004] In order to solve the technical problem that a charging pile cannot automatically retract a charging line after a car is charged, the utility model provides an automatic retracting charging pile.

[0005] The utility model is implemented by the following technical scheme: an automatic wire-retracting charging pile, comprising a charging pile body, a charging wire is provided on one side of the charging pile body, a wire-retracting assembly capable of automatically retracting the charging wire is provided on one side of the charging pile body, a driving assembly for driving the wire-retracting assembly to retract the charging wire is provided on one side of the wire-retracting assembly, and the wire-retracting assembly comprises a first protective box fixedly mounted on one side of the charging pile body, a first wire-retracting plate arranged inside the first protective box, and a second wire-retracting plate arranged inside the first protective box.

[0006] Through the above technical solution, when the car is finished charging, the charging cable is unplugged, and the sensor on the charging head will sense that it has been separated, so that the charging pile body will issue a command to the drive component to drive the take-up component to retract the cable.

[0007] As a further improvement of the above scheme, a rotation groove is provided on one side of the first wire taking-up plate and one side of the second wire taking-up plate, and a rotation shaft is rotatably installed inside the two rotation grooves. Rolling cylinders are fixedly sleeved on the two rotation shafts, and limiting grooves adapted to the charging cable are provided on the circumferential surfaces of the two rolling cylinders.

[0008] Through the above technical solution, the first wire taking-up plate and the second wire taking-up plate slide, and the charging wire is pulled, thereby completing the taking-up of the charging wire.

[0009] As a further improvement of the above solution, one side of the two rolling columns is provided with a limiting plate fixedly mounted to the first wire take-up plate or the second wire take-up plate.

[0010] Through the above technical solution, the limiting plate can prevent the charging cable from separating from the rolling column.

[0011] As a further improvement of the above solution, one side of the first take-up plate and the second take-up plate both penetrate the first protection box and are fixedly mounted with a driving block, and the two driving blocks are both arranged in an "L" shape.

[0012] Through the above technical solution, the movement of the two driving blocks will drive the first take-up plate and the second take-up plate to move.

[0013] As a further improvement of the above solution, the driving assembly includes a servo motor arranged on one side of the charging pile body and a bidirectional threaded rod fixedly installed on the output end of the servo motor, and the two driving blocks are both threadedly matched with the bidirectional threaded rod.

[0014] Through the above technical solution, when the servo motor is started, the bidirectional threaded rod will rotate, thereby causing the two drive blocks to move.

[0015] As a further improvement of the above solution, a second protection box is provided outside the first protection box, the bidirectional threaded rod and the servo motor are both located inside the second protection box, and one end of the charging cable passes through the first protection box and the second protection box.

[0016] Through the above technical solution, the second protection box can have a protective effect on the driving component.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a wire-reeling assembly and a driving assembly. When the car is fully charged and the charging line is unplugged, the sensor on the charging head will sense that they have been separated, so that the charging pile body will issue a command to the driving assembly, and the driving assembly will drive the wire-reeling assembly to reel in the charging line. This arrangement can prevent the charging line from being thrown on the ground at will and causing damage after the car is fully charged. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 An automatic wire-retracting charging pile of the present embodiment includes a charging pile body 1, a charging wire 2 is provided on one side of the charging pile body 1, a wire-retracting assembly capable of automatically retracting the charging wire 2 is provided on one side of the charging pile body 1, a driving assembly for driving the wire-retracting assembly to retract the charging wire 2 is provided on one side of the wire-retracting assembly, and the wire-retracting assembly includes a first protective box 301 fixedly mounted on one side of the charging pile body 1, a first wire-retracting plate 302 arranged inside the first protective box 301, and a second wire-retracting plate 303 arranged inside the first protective box 301. When the charging of the car is finished, the charging wire 2 is unplugged, and the sensor on the charging head will sense that it has been separated, so that the charging pile body 1 sends a command to the driving assembly to drive the wire-retracting assembly to retract the wire.

[0026] Combination Figure 2 and Figure 3 A rotating groove is provided on one side of the first wire-taking plate 302 and one side of the second wire-taking plate 303, and a rotating shaft 5 is rotatably installed inside the two rotating grooves. A rolling column 6 is fixedly sleeved on the two rotating shafts 5, and a limiting groove adapted to the charging line 2 is provided on the circumferential surface of the two rolling columns 6. A limiting plate 7 fixedly installed with the first wire-taking plate 302 or the second wire-taking plate 303 is provided on one side of the two rolling columns 6. One side of the first wire-taking plate 302 and the second wire-taking plate 303 penetrates the first protective box 301 and is fixedly installed with a driving block 8. The two driving blocks 8 are both arranged in an "L" shape. When the first wire-taking plate 302 and the second wire-taking plate 303 slide, the charging line 2 will be pulled, thereby completing the winding of the charging line, and the limiting plate 7 will prevent the charging line 2 from separating from the rolling column 6.

[0027] Combination Figure 2The driving assembly includes a servo motor 401 arranged on one side of the charging pile body 1, and a bidirectional threaded rod 402 fixedly installed on the output end of the servo motor 401. The two driving blocks 8 are threadedly matched with the bidirectional threaded rod 402. A second protection box 9 is provided on the outside of the first protection box 301. The bidirectional threaded rod 402 and the servo motor 401 are both located inside the second protection box 9. One end of the charging line 2 passes through the first protection box 301 and the second protection box 9. When the servo motor 401 is started, the bidirectional threaded rod 402 will rotate, thereby causing the two driving blocks 8 to move. The movement of the two driving blocks 8 will drive the first take-up plate 302 and the second take-up plate 303 to move.

[0028] The implementation principle of an automatic wire-winding charging pile in the embodiment of the present application is as follows: a sensor is provided on the existing charging cable 2 plug to confirm whether the charging interface and the charging socket are connected. Before charging starts, the sensor detects the connection status between the plug and the socket to ensure that the charging process can be carried out safely and effectively. When the car is finished charging and the charging cable 2 plug is unplugged, the signal will be transmitted to the charging pile body 1, and the charging pile body 1 will start the servo motor 401 to rotate the bidirectional threaded rod 402, so that the two drive blocks 8 move in a direction close to each other, which will move the first wire-winding plate 302 and the second wire-winding plate 303, and the two rolling columns 6 will push the charging cable 2 to bend the charging cable 2 inside the first protective box 301. Since the charging cable 2 is installed on the charging pile body 1 One end of the charging pile 301 is fixed, so the external charging line 2 will be pulled into the inside of the first protective box 301, thereby completing the automatic winding of the charging line 2. When the charging line 2 is needed, after setting the charging time, the charging pile body 1 will start the servo motor 401 and let the bidirectional threaded rod 402 rotate in the opposite direction, so that the two drive blocks 8 move away from each other, and the limit plate 7 will move together with the first winding plate 302 and the second winding plate 303, thereby releasing the pulling restriction on the charging line 2, so that the charging line 2 can be pulled out of the first protective box 301, and the charging line 2 can be started after the plug of the charging line 2 is fixed to the car interface. There is a gap between the limit plate 7 and the charging line 2. The limit plate 7 only prevents the charging line 2 from separating from the rolling column 6. This setting can prevent the charging line 2 from being thrown on the ground at will and causing damage after the car charging is completed.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
