[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-4This utility model provides a technical solution: an electric opening and closing fully automatic cable reel charging station, including a cylindrical housing 1, a cable reel 4, a cable 6, and a charging gun 7. The housing 1 has a detachable front panel and a back panel 2 installed at its front and rear ends, respectively. The charging gun 7 is installed at the front end of the cable 6. The cable reel 4 is eccentrically installed inside the housing 1, and the tail end of the cable 6 is connected to the cable reel 4. A door opening 3 is provided on the side of the housing 1 for pulling out the cable 6 and the charging gun 7. The charging gun 7 can be pulled into the housing 1 through the door opening 3 for storage. The cable reel 4 is driven by a spiral spring 5 to achieve winding rotation. A radially penetrating pipe joint 17 is fixedly installed on the top of the housing 1. The pipe joint 17 is used for installing this device and for the entry and exit of the cable.

[0016] The take-up reel 4 has a circular mounting groove in the middle, and the spiral spring 5 is placed in the mounting groove. The outer end of the spiral spring 5 is connected to the mounting groove. The spiral spring 5 has a square shaft 16 in the middle. A radial baffle is fixedly installed on the outer side of the mounting groove. The square shaft 16 passes through the circular hole in the middle of the baffle. The outer end of the square shaft 16 is fixedly installed on the inner side of the panel. When the cable 6 is pulled out, the spiral spring 5 tightens. Two axial limiting plates 8 are fixedly installed on the back plate 2. The two limiting plates 8 are located on the upper and lower sides of the take-up reel 4, respectively. The limiting plates 8 are used to prevent the wound cable 6 from unwinding.

[0017] A rotatable arc-shaped door 9 is installed at the center of the back panel 2. A motor b14 is installed on the rear side of the back panel 2. The motor b14 drives the arc-shaped door 9 to rotate. When the arc-shaped door 9 rotates to the position of the door hole 3, it can cover and seal the door hole 3. After the cable is retracted, the charging gun 7 can be retracted into the housing 1. After the arc-shaped door 9 is closed, the housing 1 is a closed space, which helps to protect the charging gun 7. An electrical box 13 is fixedly installed on the rear side of the back panel 2. A circuit board is also installed on the rear side of the back panel 2. The electrical box 13 is used to cover the motor b14 and the circuit board, and serves a protective function. A Z-shaped support 10 (the support 10 is a bent sheet metal part) is installed on the inner side of the back plate 2. A motor a15 is installed on the rear side of the support 10, and a drive wheel 11 is installed on the front side of the support 10. The central shaft of the drive wheel 11 is connected to the output end of the motor a15. A swing arm is hinged to the front of the support 10. A tension wheel 12 is installed on the movable end of the swing arm. The swing arm is subjected to tension in the direction of the drive wheel 11 by a tension spring. The cable 6 passes between the drive wheel 11 and the tension wheel 12. The cable 6 is pressed between the drive wheel 11 and the tension wheel 12, which can increase the friction of the drive. Both the drive wheel 11 and the tension wheel 12 are provided with annular grooves on their outer sides. The annular grooves are used to fit and snap onto the cable.

[0018] Working principle: An arc-shaped door 9, rotating around a center, is installed inside the cavity of the housing 1. Winding the cable allows the charging gun 7 to be wound into the housing 1 along with the cable. The arc-shaped door 9, driven by a motor b14 on the back, rotates to the appropriate position to cover and seal the door opening 3. The charging gun 7 is placed in a sealed cavity, making it waterproof and moisture-proof. Forward rotation of the drive wheel 11 gradually feeds the cable 6 and charging gun 7 out of the door opening 3, while reverse rotation of the drive wheel 11 assists in winding and retracting the cable 6.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
