Description

Technical Field

[0001] The utility model relates to the technical field of intelligent charging piles, in particular to an intelligent charging pile which is convenient for storing cables. Background Art

[0002] With the popularity of electric vehicles, the charging pile industry has also developed rapidly. It is mainly used for charging electric vehicles. The charging pile mainly includes a main body and a charging gun connected to the main body through a cable. When charging, the charging gun is removed from the main body, and then the extendable cable is dragged to insert the charging gun into the charging port of the electric vehicle for charging. However, when using existing charging piles, the cables are usually wound into a circle and hung on the side of the main body, making it difficult to store longer cables. Long-term exposure to the air accelerates the aging of the cables. In addition, when charging, for better use, the cables of existing charging piles are often set longer. However, the longer cables will be dragged on the ground and rubbed against the ground, which can easily cause damage to the appearance of the cables. Moreover, due to the gravity and tension of the cables, the inventors have found that after the charging gun is used for a long time, the position where it is connected to the main body is prone to loosening. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a smart charging pile which is convenient for storing cables.

[0004] The technical solution of this utility model is as follows:

[0008] A sliding groove for the cable to move up and down is vertically opened on the side of the base.

[0009] In order to guide the cable, two guide wheels are arranged on one side of the first winding wheel close to the center of the base, and the two guide wheels are arranged vertically at intervals, and the cable passes between the two guide wheels.

[0010] In order to improve the guiding effect of the guiding wheel, the guiding wheel is arranged away from the center of the base relative to the connection position of the cable and the display end.

Detailed Embodiments

[0027] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings.

[0028] Embodiment

[0029] As mentioned in the background art, when charging an electric vehicle, a charging pile is required. The cables of existing charging piles are usually wound and hung outside the charging pile main body, which is prone to aging. Moreover, the cable 3 is often dragged on the ground during charging, and the outer surface is easily worn. Also, due to the gravity and tension of the cable 3, the insertion position of the charging gun 9 and the main body part is likely to become loose. Therefore, the inventor has improved on the existing charging pile and designed a charging pile that facilitates the storage of the cable 3. The following will be specifically described with reference to the drawings.

[0030] This embodiment provides an intelligent charging pile that facilitates cable storage. Combining Figure 1 , including a base 1, a display end 2 is provided on the base 1, and two cables 3 are provided inside the base 1. The cable 3 is electrically connected to the bottom of the display end 2. A charging device is provided inside the display end 2 and the base 1. The relevant electrical components are not shown in the figure. After being connected, the cable 3 can be powered on. Here, the existing technology can be adopted. The charging circuit is not designed in this solution, so no redundant description will be given.

[0031] In this embodiment, two first wire winding wheels 4 are arranged at the top inside the base 1. The positions of the first wire winding wheels 4 are fixed and rotatably connected. The two first wire winding wheels 4 are respectively arranged corresponding to two cables 3 and are respectively located on both sides of the top inside the base 1, symmetrically arranged. And an installation frame 5 is slidably arranged inside the base 1 below them. Installation frames 5 are correspondingly arranged below both of the two first wire winding wheels 4. The installation frame 5 can slide vertically along the side wall of the base 1 inside the base 1. And in order to improve the sliding stability, sliding grooves with the same width as the installation frame 5 can be opened on the side wall to limit the installation frame 5. And a return spring 6 is connected between the installation frame 5 and the bottom inside the base 1. The return spring 6 is a tension spring. When the installation frame 5 moves upward, the return spring 6 can be stretched. Secondly, a second wire winding wheel 7 and a third wire winding wheel 8 are installed at both ends of the installation frame 5. The second wire winding wheel 7 and the third wire winding wheel 8 are of the same size and are installed on the front end face of the installation frame 5 and are rotatably connected to the installation frame 5. The cable 3 sequentially passes around the third wire winding wheel 8, the first wire winding wheel 4 and the second wire winding wheel 7 from the display end 2 and then passes out of the base 1 and is connected to the charging gun 9. And the charging gun 9 is inserted into the side of the display end 2. Through the insertion of the charging gun 9 into the display end 2, the cable 3 can be fixed.

[0032] On the basis of the above structure, two guide wheels 11 are arranged on one side of the first wire winding wheel 4 close to the center of the base 1. And the two guide wheels 11 are arranged at a vertical interval. And two guide wheels 11 are correspondingly arranged on one side of each of the two first wire winding wheels 4. And the cable 3 passes between the two guide wheels 11. And the guide wheels 11 are arranged away from the center of the base 1 relative to the connection position of the cable 3 and the display end 2, so that the guide wheels 11 are located between the second wire winding wheel 7 and the position where the charging gun 9 is connected to the bottom of the display end 2. The minimum dimension between the two guide wheels 11 is the same as the diameter of the cable 3, which can guide and limit the cable 3.

[0033] Secondly, in order to enable the installation frame 5 to move upward along with the cable 3 when the cable 3 is pulled out, a sliding groove 10 for the up and down movement of the cable 3 is vertically opened on the side of the base 1. The cable 3 passes out of the base 1 at the sliding groove 10. And in order to limit the second wire winding wheel 7, one side of the second wire winding wheel 7 extends out of the base 1 through the sliding groove 10. And the width of the sliding groove 10 is slightly larger than the width of the second wire winding wheel 7. When the second wire winding wheel 7 moves up and down along with the installation frame 5, the second wire winding wheel 7 moves up and down along the sliding groove 10.

[0034] When charging is required, unplug the charging gun 9 on one side of the display end 2 and pull the cable 3 toward the side away from the base 1. While the cable 3 moves outward along the first cable reel 4, the second cable reel 7, and the third cable reel 8, the cable 3 can push the second cable reel 7 and the third cable reel 8 upward. Subsequently, the mounting bracket 5 slides upward inside the base 1, and the elastic force of the return spring 6 applies a downward force to the cable 3, keeping the cable 3 in a tensioned state and avoiding dragging on the ground until it is inserted into the charging port of the vehicle. After charging is completed, unplug the charging gun 9, hold the charging gun 9 and insert it into the display end 2, and the elastic force of the return spring 6 can push the cable 3 to retract.

[0035] In this embodiment, to solve the problem that the charging gun 9 is prone to looseness when plugged into the side of the display end 2, in combination with Figure 2 and Figure 3 , mounting seats 12 for plugging in the charging gun 9 are provided on both sides of the display end 2, and a fastener is connected between the charging gun 9 and the mounting seat 12 to strengthen the connection with the mounting seat 12. Specifically, U-shaped rods 13 are provided on both sides of the charging gun 9, and the opening faces the charging gun 9. Plugging seats 14 are provided on both sides of the mounting seat 12. One end of the U-shaped rod 13 is rotatably connected to the charging gun 9, and the other end can be inserted into the plugging seat 14. After being inserted into the plugging seat 14, the side of the charging gun 9 is connected and fixed to the side of the mounting seat 12. Moreover, two U-shaped rods 13 are respectively provided on both sides of the charging gun 9, and the number of plugging seats 14 is the same as that of the U-shaped rods 13, that is, two U-shaped rods 13 are provided on both sides of the charging gun 9 to be fixed to the mounting seat 12, improving the fastening property.

[0036] Moreover, to facilitate the insertion or extraction of the U-shaped rod 13 into or from the plugging seat 14, two design methods are provided in this solution. One is to make the U-shaped rod 13 of an elastic material. When the plugging seat 14 needs to be pulled out, pull the U-shaped rod 13 outward until the U-shaped rod 13 is separated from the plugging seat 14, and then unplug the charging gun 9. Secondly, another implementation method can also be adopted. Telescopic rods 15 are rotatably connected to both sides of the charging gun 9, and the U-shaped rod 13 is connected to the telescopic end of the telescopic rod 15. One end of the U-shaped rod 13 connected to the telescopic rod 15 can move along with the telescopic rod 15. And to improve the stability during fixation, the telescopic rod 15 can be of a damping type. When the charging gun 9 needs to be removed, pull the U-shaped rod 13 outward as a whole, so that the U-shaped rod 13 is separated from the plugging seat 14.

[0037] On the basis of the above structure, a plug rod 16 is provided at one end of the opening of the U-shaped rod 13 close to the telescopic rod 15, and a jack 17 is formed on the side of the charging gun 9, and the jack 17 is located on the rotation path of the plug rod 16 along with the rotation of the U-shaped rod 13. The design of the plug rod 16 is further designed on the basis of the design of the telescopic rod 15, so that after the U-shaped rod 13 is pulled out along with the telescopic rod 15, in order to prevent it from rotating randomly, the telescopic rod 15 is rotated around the rotation point until the plug rod 16 is aligned with the jack 17, and then the U-shaped rod 13 is pushed until the plug rod 16 enters the jack 17 to realize the fixation of the U-shaped rod 13.
