Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, specifically to an outdoor dustproof charging gun port. Background Technology

[0002] With the increasing popularity of electric vehicles, outdoor charging equipment is also becoming more widespread. Electric vehicles need to be charged using a charging gun. While home charging stations are usually installed at home, outdoor charging stations are generally exposed to the outside world, especially roadside charging stations. When charging a car, the charging gun needs to be taken out of the outdoor charging box and inserted into the car's charging port. At this time, the charging gun port of the outdoor charging box is exposed to the air. Due to factors such as vehicles driving on the roadside, dust can easily flow. Traditional outdoor charging boxes do not have a dustproof structure for the charging gun port, and flowing dust can easily enter the charging gun port when it is used, which can affect the service life of the charging gun in the long run. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an outdoor dustproof charging gun port to solve the problem mentioned in the background art that the traditional outdoor charging gun port is open and cannot prevent dust when the charging gun is in use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor dustproof charging gun port, comprising a charging port and a protective cover with an opening, the protective cover being disposed on the outside of the charging port, a fixing rod being disposed at the lower end of the opening of the protective cover, the fixing rod being fixedly connected to the protective cover, a rotating sleeve being sleeved on the fixing rod, a roller shutter being disposed on the rotating sleeve, one end of the roller shutter being fixedly connected to the rotating sleeve, and the other end being disposed of a sliding rod for sliding along the end face of the protective cover in the direction of the opening, a slide rail being disposed on the end face of the protective cover in the direction of the opening, after the sliding rod slides along the slide rail to the upper end of the opening of the protective cover, the roller shutter can cover the charging port.

[0005] As a further improvement of this utility model, a through hole is provided on both sides of the rotating sleeve, and the two through holes are arranged at the same horizontal line position.

[0006] As a further improvement of this utility model, an elastic strap is provided at each end of the fixing rod corresponding to each through hole. One end of the elastic strap is fixedly connected to the fixing rod, and the other end is tied in the through hole. After the rotating sleeve rotates, it can drive the elastic strap to wrap around the fixing rod.

[0007] As a further improvement of this utility model, a receiving section is provided between the rotating sleeve and the fixed rod, the through hole is provided at one end of the receiving section facing the rotating sleeve, and the elastic strap is provided at one end of the fixed rod near the other end of the receiving section, and the elastic strap can be wrapped around the receiving section.

[0008] As a further improvement of this utility model, a pull ring is provided at the upper end of the opening direction of the protective cover, and a hook is provided on the slide rod to cooperate with the pull ring to position the roller shutter. The hook can be connected to the pull ring.

[0009] As a further improvement of this utility model, a slider is provided on the slide rod at the position corresponding to the slide rail, and the slider slides in cooperation with the slide rail.

[0010] Compared with existing technologies, this utility model provides an outdoor dustproof charging port with the following advantages: By using a protective cover to provide basic protection for the charging port, and in conjunction with the coordinated structure of the roller shutter, rotating sleeve, sliding rod, and slide rail, it overcomes the problem of dust accumulation at the charging port in outdoor charging scenarios. The cooperation between the fixed rod and the rotating sleeve allows the roller shutter to be retracted and extended. When the sliding rod slides along the slide rail to the upper end of the protective cover opening, the roller shutter can cover the charging port, achieving dust protection and preventing dust from entering the charging port and affecting the stability of charging contact or damaging internal components. The overall structure is easy to operate; simply sliding the sliding rod is enough to switch between protection modes, making it suitable for complex outdoor environments.

[0017] As shown in the figure, to achieve the above-mentioned objective, this utility model provides an outdoor dustproof charging gun port, including a charging port 1 and a protective cover 2 with an opening. The protective cover 2 covers the outside of the charging port 1. A fixing rod 3 is provided at the lower end of the opening of the protective cover 2. The fixing rod 3 is fixedly connected to the protective cover 2. A rotating sleeve 4 is sleeved on the fixing rod 3. A roller shutter 5 is provided on the rotating sleeve 4. One end of the roller shutter 5 is fixedly connected to the rotating sleeve 4, and the other end is provided with a sliding rod 6 for sliding along the end face of the opening direction of the protective cover 2. A slide rail 7 is provided on the end face of the protective cover 2 in the opening direction. After the sliding rod 6 slides along the slide rail 7 to the upper end of the opening of the protective cover 2, the roller shutter 5 can cover the charging port 1.

[0018] In implementation, the protective cover 2 is a shell structure with one open end, covering the outside of the charging port 1. The opening of the protective cover 2 faces the direction that facilitates the insertion and removal of the charging gun. A fixing rod 3 is fixedly connected to the lower end of the opening of the protective cover 2. The extension direction of the fixing rod 3 is consistent with the width direction of the opening of the protective cover 2. A rotating sleeve 4 is movably fitted on the fixing rod 3, and the rotating sleeve 4 can rotate circumferentially along the axis of the fixing rod 3. One end of the roller shutter 5 is fixedly connected to the outer wall of the rotating sleeve 4, and the other end of the roller shutter 5 is fixedly connected to a sliding rod 6. The length of the sliding rod 6 is adapted to the width of the opening of the protective cover 2. On the inner side of the two end faces in the direction of the opening of the protective cover 2, a slide rail 7 is respectively opened. The two slide rails 7 are symmetrically and parallelly arranged. The two ends of the sliding rod 6 are respectively embedded in the corresponding slide rail 7, so that the sliding rod 6 can slide along the extension direction of the slide rail 7. When dust protection is required for charging port 1, the operator pulls the slide bar 6, causing it to slide upwards along the slide rail 7 from the lower end of the opening of the protective cover 2. Simultaneously, the roller shutter 5 unfolds with the movement of the slide bar 6. When the slide bar 6 slides to the upper end of the opening of the protective cover 2, the roller shutter 5 is fully unfolded and covers the charging port 1, achieving dust protection. When charging port 1 needs to be used, the slide bar 6 is pulled in the opposite direction, causing the roller shutter 5 to roll up onto the rotating sleeve 4.

[0019] As an improved specific implementation, a through hole 8 is provided on both sides of the rotating sleeve 4, and the two through holes 8 are arranged at the same horizontal line position.

[0020] In this implementation, a through hole 8 is made on each of the two end faces of the rotating sleeve 4. The two through holes 8 are located on the same horizontal line, and their axes are collinear, perpendicular to the central axis of the rotating sleeve 4. The inner diameter of the through hole 8 must meet the installation requirements of subsequent components, and the hole wall can be smooth to avoid excessive friction between the assembled components and the hole wall. The positions of the two through holes 8 must correspond to ensure they are on the same horizontal line, preventing the subsequent linkage structure from malfunctioning due to positional deviations of the through holes 8. During assembly, the rotating sleeve 4 remains movably fitted onto the fixed rod 3. The opening of the through holes 8 does not affect the circumferential rotation of the rotating sleeve 4 on the fixed rod 3, ensuring that the basic function of the rotating sleeve 4 is not affected, while providing stable structural support for the subsequent installation of the elastic strap 9.

[0021] As an improved specific implementation, an elastic strap 9 is provided at each end of the fixed rod 3 corresponding to each through hole 8. One end of the elastic strap 9 is fixedly connected to the fixed rod 3, and the other end is tied in the through hole. After the rotating sleeve 4 rotates, it can drive the elastic strap 9 to wrap around the fixed rod 3.

[0022] In this implementation, an elastic strap 9 is fixedly connected to both ends of the fixed rod 3, corresponding to the through holes 8 on both sides of the rotating sleeve 4. The elastic strap 9 can be implemented using either an elastic rope or an elastic band. The first implementation uses an elastic rope, with one end fixed to the end of the fixed rod 3 by knotting or gluing, and the other end passing through the corresponding through hole 8 and then secured at the through hole 8. The second implementation uses an elastic band, with one end fixed to the end of the fixed rod 3 by riveting, and the other end passing through the corresponding through hole 8 and then secured at the through hole 8 by a buckle. When the operator pulls the slide bar 6 to unfold the roller blind 5, the roller blind 5 will cause the rotating sleeve 4 to rotate circumferentially. During the rotation of the rotating sleeve 4, the perforation 8 will rotate synchronously, thereby pulling the elastic strap 9 to wrap around the fixed rod 3. At this time, the elastic strap 9 is in a stretched state, accumulating elastic restoring force. When it is necessary to retract the roller blind 5, the limit of the slide bar 6 is released, and the elastic restoring force of the elastic strap 9 will cause the rotating sleeve 4 to rotate in the opposite direction, thereby automatically retracting the roller blind 5 without manual operation, improving the convenience of operation.

[0023] As an improved specific implementation, a receiving section 10 is provided between the rotating sleeve 4 and the fixed rod 3. The through hole 8 is provided at one end of the receiving section 10 facing the rotating sleeve 4. The elastic strap 9 is connected to the fixed rod 3 at one end near the other end of the receiving section 10. The elastic strap 9 can be wrapped around the receiving section 10.

[0024] In this design, a receiving section 10 is provided between the rotating sleeve 4 and the fixed rod 3. The receiving section 10 is a smooth rod 6 on the fixed rod 3, and its length is adapted to the length of the rotating sleeve 4. In this design, the length of the receiving section 10 is sufficient for the elastic strap 9 to be wound around without insufficient space. The through holes 8 on both sides of the rotating sleeve 4 are provided at the ends of the receiving section 10 facing the rotating sleeve 4, ensuring that the positions of the through holes 8 and the receiving section 10 are aligned. The end of the elastic strap 9 that connects to the fixed rod 3 is located close to the other end of the receiving section 10, so that the installation position of the elastic strap 9 and the position of the through holes 8 are respectively at the two ends of the receiving section 10. As the rotating sleeve 4 rotates and drives the elastic strap 9 to wind, the elastic strap 9 will precisely wind around the rod body of the receiving section 10. The receiving section 10 provides a dedicated winding space for the elastic strap 9, preventing friction between the elastic strap 9 and the end face of the rotating sleeve 4 or other parts of the fixing rod 3, thus preventing damage to the elastic strap 9 due to friction and extending its service life. At the same time, the setting of the receiving section 10 makes the winding process of the elastic strap 9 more regular, preventing the elastic strap 9 from knotting or misaligning, ensuring that the elastic restoring force of the elastic strap 9 can be stably transmitted to the rotating sleeve 4, and ensuring the smoothness of the roller shutter 5's winding action.

[0025] As an improved embodiment, a pull ring 11 is provided at the upper end of the opening direction of the protective cover 2, and a hook 12 is provided on the slide rod 6 to cooperate with the pull ring 11 to position the roller shutter 5. The hook 12 can be connected to the pull ring 11.

[0026] In this implementation, a pull ring 11 is fixedly connected to the upper end of the opening of the protective cover 2. The pull ring 11 can be either a metal pull ring 11 or a plastic pull ring 11. This solution preferably uses a metal pull ring 11, which is fixed to the end face of the upper opening of the protective cover 2 by welding. The metal pull ring 11 has high strength and can adapt to complex outdoor environments.

[0027] As an improved embodiment, a slider 13 is provided on the slider 6 at the position corresponding to the slide rail 7, and the slider 13 slides in cooperation with the slide rail 7.

[0028] In this implementation, a slider 13 is fixedly connected to each end of the slide rod 6, corresponding to the position of the slide rail 7 on the opening end face of the protective cover 2. The shape of the slider 13 matches the shape of the slide rail 7. Metal sliders 13 are used and are fixed to the ends of the slide rod 6 by bolts. The metal sliders 13 have high strength, long service life, and can adapt to high-frequency sliding operations. The dimensions of the slider 13 must precisely match the dimensions of the slide rail 7, allowing the slider 13 to be embedded in the slide rail 7 and slide smoothly along the extension direction of the slide rail 7. The slider 13 and the slide rail 7 have a clearance fit, and the clearance size must be controlled within a reasonable range to ensure smooth sliding of the slider 13 while preventing it from wobbling within the slide rail 7. This sliding fit between the slider 13 and the slide rail 7 effectively improves the stability of the slide rod 6 during sliding, preventing it from falling off or jamming, and ensuring that the roller shutter 5 can be smoothly opened or rolled up.
