Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly relates to an expandable new energy charging pile and a protection method thereof. Background Art

[0002] As a key link in the new energy vehicle industry chain, new energy charging piles are of great significance for promoting green travel and driving the transformation of the energy structure. With the progress of technology and market demand, new energy charging piles will be more widely used and developed in depth in the future.

[0003] Chinese Patent with Publication No. CN117885574B discloses an expandable new energy charging pile and its working method, including a charging pile base, a charging pile column rod, a charging gun and a charging pile control cabinet. By sleeving a protective box body outside the charging pile control cabinet, the charging pile control cabinet enters the protective box body through a connecting groove, and drives two protective doors to rotate synchronously and close towards each other. The two protective doors and the protective box body protect the charging pile control cabinet, avoiding the charging pile control cabinet being exposed outside and damaged by collision, and at the same time avoiding the charging pile control cabinet from being exposed to wind, sun and rain, and improving the service life of the charging pile control cabinet.

[0004] However, the above disclosed solution has the following deficiencies: The charging gun and the cable connecting the charging gun are both directly exposed outside. Firstly, it affects the overall aesthetics. Secondly, the exposed cable may be damaged or the connection line may become loose due to the continuous change of the ambient temperature, animal biting and possible physical damage. The possibility of the charging gun getting water and dust is also greater. Especially for charging piles used in outdoor environments, the exposed charging gun and cable are more likely to be damaged. Summary of the Invention

Detailed implementation manners

[0036] In the first embodiment, as Figures 1-5 shown, a deployable new - energy charging pile proposed by the present invention includes a mounting post 1. The mounting post 1 is of a hollow structure. A fixed base 2 is provided at the bottom of the mounting post 1. Multiple vertical mounting holes are provided on the fixed base 2, and the fixed base 2 is fixedly installed by multiple bolts. A protective shell 3 is provided on the front surface of the mounting post 1. A charging pile body 4 is arranged inside the protective shell 3. A charging pile inlet wire 5 is arranged on the charging pile body 4. The charging pile inlet wire 5 extends into the mounting post 1 and is connected to an external circuit. A front cover 34 of the protective shell is provided at the front end of the protective shell 3. Opening the front cover 34 of the protective shell can repair the internal structure of the protective shell 3. The charging pile body 4 is wirelessly communicatively connected to the user's mobile phone, such as Bluetooth connection, and relevant charging operations are carried out through a mobile phone APP; further includes:

[0037] A cable winding disc 6, which is arranged on the inner wall of the rear side of the protective shell 3, and the charging pile body 4 is located inside the cable winding disc 6;

[0038] A rotating ring 7, which is rotatably arranged on the opening of the outer peripheral surface of the cable winding disc 6, and a wire passing opening 8 is arranged on the rotating ring 7;

[0039] The charging cable 10 has one end connected to the output end of the charging pile body 4, and the other end extends into the cable winding disc 6, passes through the wire routing opening 8, and is connected to a charging gun 11. In an optional embodiment, two rollers 9 are rotatably arranged in the wire routing opening 8. Annular grooves are arranged on the two rollers 9, and the two annular grooves face each other. The charging cable 10 passes through the two annular grooves, and the two rollers 9 provide protection for the charging cable 10 during winding and unwinding.

[0040] The foot pedal 20 is slidably arranged on the mounting post 1 in the vertical direction. The foot pedal 20 is arranged on the front of the mounting post 1 for easy foot operation. In an optional embodiment, a chute 21 is vertically arranged on the front of the mounting post 1. A slider is arranged on the foot pedal 20, and the slider cooperates with the chute 21 for sliding. A follow-up mechanism is arranged on the protective shell 3 and the mounting post 1. When the foot pedal 20 is depressed, the rotating ring 7 is driven to rotate through the follow-up mechanism. After the foot pedal 20 is depressed to the bottom, the charging cable 10 is automatically wound around the cable winding disc 6, which is convenient to use. When the charging cable 10 is pulled outwards, the foot pedal 20 slides upwards.

[0041] And a bottom unfolding mechanism is arranged at the bottom of the protective shell 3. An avoidance opening is arranged at the bottom of the protective shell 3. The bottom unfolding mechanism is used to store the charging gun 11 and can rotate to change the state. The bottom unfolding mechanism includes a charging state and a non-charging state. The avoidance opening is closed in both states. In the charging state, the charging gun 11 is pulled out, and in the non-charging state, the charging gun 11 is retracted into the protective shell 3.

[0042] Embodiment 2, as Figure 2 shown, a deployable new energy charging pile proposed by the present invention. Compared with Embodiment 1, this embodiment details the optimized wire routing method of the charging cable 10.

[0043] A limiting plate 12 is arranged on the inner wall of the protective shell 3. The limiting plate 12 is located in front of the cable winding disc 6. A lead hole 13 is arranged in the middle of the limiting plate 12. The charging cable 10 passes through the lead hole 13. In this embodiment, the limiting plate 12 is located at the middle position in front of the cable winding disc 6 and is horizontally arranged. The limiting plate 12 includes two splicing plates, and the two splicing plates are respectively installed on the left and right inner walls of the protective shell 3 through bolts. Semi-circular holes are arranged at the ends of the two splicing plates, and the two semi-circular holes form the lead hole 13. By arranging the lead hole 13 in the front to guide the wire routing of the charging cable 10, it is convenient to drive the rotating ring 7 to rotate smoothly when the charging cable 10 is pulled outwards, and avoid jamming due to angle problems.

[0044] Embodiment 3, as Figures 2-4 shown, a deployable new energy charging pile proposed by the present invention. Compared with Embodiment 1 or Embodiment 2, this embodiment details the structure of the follow-up mechanism.

[0045] The follower mechanism includes an annular gear 14 arranged on the outer periphery of the rotating ring 7, a wire winding wheel 16 rotatably arranged on the inner wall of the top of the mounting post 1, a gear a 15 arranged on the rotating shaft of the wire winding wheel 16 extending into the protective housing 3, and a pull rope 18 wound around the wire winding wheel 16. The gear a 15 meshes with the annular gear 14, and the bottom of the pull rope 18 passes through the front of the mounting post 1 and is connected to the foot pedal 20.

[0046] Furthermore, a support plate 17 is arranged on the inner wall of the top of the mounting post 1, and the wire winding wheel 16 is rotatably arranged on the support plate 17. The rotational connection method can be achieved by means of a bearing; a rain shield 19 is arranged on the front of the mounting post 1. The bottom of the rain shield 19 is open, and the position where the pull rope 18 passes through the mounting post 1 is located inside the rain shield 19. The rain shield 19 can prevent rainwater from entering the mounting post 1.

[0047] Embodiment 4, as Figures 6-7 shown, a deployable new energy charging pile proposed by the present invention. Compared with Embodiment 1, the structure of the bottom deployment mechanism is introduced in detail in this embodiment.

[0048] The bottom deployment mechanism includes a rotating shaft 22 rotatably arranged above the inner wall of the protective housing 3, a power assembly arranged on the inner wall of the protective housing 3 to drive the rotating shaft 22 to rotate at a fixed angle, a support frame 23 arranged on the rotating shaft 22 and passing through the avoidance opening, and an upper sealing plate 24 and a lower sealing plate 25 arranged on the support frame 23; the upper sealing plate 24 is located inside the protective housing 3, and the lower sealing plate 25 is located below the protective housing 3. In the charging state, the upper sealing plate 24 flips downward to close the avoidance opening. In the non-charging state, the charging gun 11 is placed on the lower sealing plate 25, and the lower sealing plate 25 flips upward to close the avoidance opening. A wire passing hole for the charging cable 10 to pass through is arranged on the upper sealing plate 24, and a guiding ring 26 for the charging cable 10 to pass through is arranged on the lower sealing plate 25; in order to enable the charging gun 11 to be stably placed on the lower sealing plate 25, a limiting block 28 is arranged on the charging gun 11, two limiting holes are opened on the limiting block 28, and two limiting rods 27 are arranged on the lower sealing plate 25. Aligning the limiting rods 27 to pass through the two limiting holes can simply fix the charging gun 11 and prevent the charging gun 11 from slipping off during the upward flipping process of the lower sealing plate 25.

[0049] Furthermore, the power assembly includes a motor 31 arranged on the inner wall of the protective housing 3 through a motor seat 32, a gear c 30 arranged on the output shaft of the motor 31, and a gear b 29 arranged on the rotating shaft 22. The gear b 29 and the gear c 30 mesh; a control system 33 is arranged on the inner wall of the protective housing 3. The control system 33 is connected to the motor 31 for control, and the control system 33 is wirelessly communicatively connected to the user's mobile phone. In this embodiment, the motor 31 is an encoder motor, which can accurately control the rotation angle. In the present invention, the rotation angle required for the rotating shaft 22 to change the state is 33 degrees.

[0050] Embodiment 5. A protection method for an expandable new energy charging pile proposed by the present invention uses the expandable new energy charging pile of Embodiment 4, and specifically includes the following steps:

[0051] S1. When charging is required, the user wirelessly connects to the control system 33 through the mobile phone, and controls the motor 31 to rotate counterclockwise by 33 degrees through the control system 33. The lower sealing plate 25 flips downward, and the upper sealing plate 24 flips downward to close the avoidance opening, realizing the sealing of the protective shell 3 in the charging state;

[0052] S2. The user picks up the charging gun 11 and pulls out the charging cable 10 outward. During the process of pulling out the charging cable 10 outward, the rotating ring 7 is driven to rotate. The rotating ring 7 drives the foot pedal 20 to move upward through the follower assembly. Specifically, the rotating ring 7 drives the annular gear 14 to rotate, the annular gear 14 drives the gear a15 to rotate, the gear a15 drives the wire winding wheel 16 to rotate, and the wire winding wheel 16 starts to wind the wire. Thus, the foot pedal 20 is driven to move upward through the pull rope 18. When the foot pedal 20 moves to the uppermost position, it indicates that the charging cable 10 has been pulled out to the maximum length and cannot be pulled out any further;

[0053] S3. After charging is completed, the user removes the charging gun 11 from the new energy vehicle and places the charging gun 11 on the lower sealing plate 25, and fixes the charging gun 11 through the limiting rod 27 and the limiting hole;

[0054] S4. Step on the foot pedal 20 to the bottom with the foot, drive the rotating ring 7 to rotate through the follower assembly, and complete the rapid winding of the charging cable 10. Specifically, the foot pedal 20 drives the wire winding wheel 16 to rotate through the pull rope 18, and the wire winding wheel drives the annular gear 14 to rotate through the gear a15. The annular gear 14 drives the rotating ring 7 to rotate. The rotating ring 7 rotates, while the cable winding disc 6 is fixed, so as to continuously wind the charging cable 10 on the cable winding disc 6;

[0055] S5. The user controls the motor 31 to work through the mobile phone, the rotating shaft 22 rotates counterclockwise to flip the lower sealing plate 25 upward, and while receiving the charging gun 11 into the protective shell 3, the avoidance opening is closed, realizing the sealing of the protective shell 3 in the non-charging state.

[0056] In summary, during charging of the present invention, the charging gun 11 is located outside the protective shell 3, and the avoidance opening at the bottom of the protective shell 3 is closed by the upper sealing plate 24, which can ensure the tightness of the protective shell 3 during the charging state and provide protection for the charging pile body 4. When not charging, the charging gun 11 and the charging cable 10 are all received inside the protective shell 3, and the avoidance opening is closed by the lower sealing plate 25, which also ensures the sealing of the protective shell 3 and provides protection for the charging gun 11 and the charging cable 10, preventing damage caused by the long-term exposure of the charging gun 11 and the charging cable 10, and extending the service life of the charging pile. Moreover, the cable winding disc 6 surrounds the outer periphery of the charging pile body 4, does not occupy much space, and has a relatively compact structural layout, which is beneficial to reducing the installation space. In addition, after charging is completed, the charging cable 10 can be neatly wound and stored quickly by stepping on the foot pedal 20 with the foot. Compared with the prior art of manually winding the charging cable 10 around the charging pile body 4, it is more convenient to use.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
