Description

Technical Field

[0001] This utility model relates to the field of electric charging pile technology, and in particular to a flip-top structure for an electric charging pile. Background Technology

[0002] The charging interface of a charging station is usually covered by a protective cover to prevent dust, rainwater and other foreign objects from entering, ensuring charging safety and service life.

[0003] Currently, charging station cover structures are mainly of two types: manual and electric. Manual covers require users to open and close them manually, which is inconvenient and they do not automatically reset if forgotten to be closed, posing a safety hazard.

[0004] Existing electric flip-top structures typically use a single motor in conjunction with a complex linkage or gear mechanism to achieve opening and closing. These structures are complex, occupy a large space, and are costly. Furthermore, they have many transmission links and a relatively high failure rate. In addition, traditional electric flip-top structures often rely on a stall signal from the motor to stop when the flip-top is fully open or closed. Over time, this can damage the motor and affect its service life.

[0005] Based on this, a flip-top structure for electric charging piles is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a flip-top structure for electric charging piles.

[0007] The technical solution to achieve the purpose of this utility model is: a flip-top structure for an electric charging pile, including a bracket, and further comprising; The pile body has an interface on one side; A fixed base, wherein a cover plate is rotatably connected to the inner wall of the fixed base, a sealing ring is fixedly connected to one side of the cover plate, a worm wheel is rotatably provided on the inner wall of the fixed base, and a worm is rotatably connected to the inner wall of the fixed base, the worm meshing with the worm wheel; A rotating shaft, the surface of which is fixedly connected to an abutment rod.

[0008] In some embodiments, the pile is fixedly mounted on one side of the bracket, and the rotating shaft is rotatably connected to the inner wall of the fixed seat.

[0009] In some embodiments, the worm gear is fixedly connected to the surface of the rotating shaft, a motor is fixedly mounted on one side of the fixed base, and the output end of the motor is fixedly connected to one end of the worm.

[0010] In some embodiments, a protective shell is fixedly connected to one side of the mounting base, and the motor is disposed inside the protective shell.

[0011] In some embodiments, a connecting arm is fixedly connected to the surface of the rotating shaft, the connecting arm is fixedly connected to one side of the cover plate, and the connecting arm is disposed inside the fixed base.

[0012] Compared with existing technologies, the significant advantages of this invention are: Firstly, this utility model uses a rotating shaft to drive the contact rod to rotate. When the cover plate is closed in place, the contact rod triggers the switch inside the fixed seat, thereby cutting off the motor power supply in time. This replaces the traditional control method that relies on the motor stall signal to stop the motor, avoiding problems such as overheating of the windings and shortened lifespan caused by long-term motor stall, and improving the safety and durability of the motor. Secondly, this utility model uses a worm gear as the core transmission component, which has a simple and compact structure and occupies little space. The worm gear transmission not only runs smoothly and has low noise, but also has a reverse self-locking characteristic, which can effectively prevent the cover from being accidentally opened or closed due to external force or vibration when not driven by a motor, ensuring the protection reliability of the charging interface and the stability of the overall structure.

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This utility model provides an improved hinged cover structure for an electric charging station. The technical solution of this utility model is as follows: like Figures 1-3As shown, a flip-top structure for an electric charging pile includes a bracket 1. The bracket 1 is preferably made of high-strength aluminum alloy or stainless steel sheet by stamping and bending, which has both structural strength and environmental corrosion resistance. It can be used to fix the entire charging pile to the ground or wall. It also includes: The pile body 2 contains electrical components such as a charging control module, and an interface 3 is provided on one side of the pile body 2. The fixing seat 6 is made of high-strength nylon material or die-cast aluminum alloy and is fixedly connected to the pile body 2 by bolts. The inner wall of the fixing seat 6 is rotatably connected to the rotating shaft 9 through bearings or bushings. The rotating shaft 9 can be made of stainless steel to ensure smooth rotation and wear resistance. The inner wall of the fixing seat 6 is rotatably connected to the cover plate 4. The cover plate 4 is fixedly connected to the rotating shaft 9 through the connecting arm 8. The connecting arm 8 and the rotating shaft 9 can transmit torque through keyway or interference fit. A sealing ring 5 is fixedly connected to one side of the cover plate 4. The sealing ring 5 is preferably made of rubber and its cross section can be designed as a hollow lip structure. When the cover plate 4 is closed, the sealing ring 5 can form a tight elastic contact with the mounting surface around the interface 3, thereby achieving excellent dustproof and waterproof sealing effect. The inner wall of the fixing seat 6 is rotatably provided with a worm gear 11 and a worm 13 is rotatably connected to the inner wall of the fixing seat 6. The worm 13 meshes with the worm gear 11. A rotating shaft 9 has a contact rod 10 fixedly connected to its surface.

[0017] like Figure 3 As shown, in one embodiment, the pile body 2 is fixedly installed on one side of the bracket 1, and the rotating shaft 9 is rotatably connected to the inner wall of the fixed seat 6.

[0018] The worm gear 11 is fixedly connected to the surface of the rotating shaft 9. A motor 12 is fixedly installed on one side of the fixed base 6. The motor 12 is preferably a low-noise, long-life DC geared motor 12. The output shaft of the motor 12 is fixedly connected to one end of the worm 13 through a coupling or directly to provide power to it. The output end of the motor 12 is fixedly connected to one end of the worm 13.

[0019] A protective shell 7 is fixedly connected to one side of the mounting base 6. The motor 12 is located inside the protective shell 7. In order to protect the motor 12 from the influence of the external environment (such as rain and dust), a protective shell 7 is also fixedly connected to the side of the mounting base 6 where the motor 12 is installed.

[0020] like Figure 2 As shown, in one embodiment, a connecting arm 8 is fixedly connected to the surface of the rotating shaft 9, and the connecting arm 8 is fixedly connected to one side of the cover plate 4. The connecting arm 8 is disposed inside the fixed base 6.

[0021] The specific working method is as follows: when it is necessary to open or close the cover plate 4, start the motor 12, the motor 12 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 11 that meshes with it to rotate, the worm wheel 11 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the cover plate 4 to rotate around the fixed seat 6 through the connecting arm 8, so as to realize the opening or closing of the cover plate 4. During the closing process of the cover plate 4, the rotating shaft 9 drives the contact rod 10 fixed on its surface to rotate synchronously. When the cover plate 4 is fully closed, the contact rod 10 rotates to contact the switch installed inside the fixed base 6, triggering the switch signal, thereby cutting off the power supply to the motor 12 and stopping the motor 12 from running. By using the cooperation of the contact rod 10 and the switch, automatic power-off control is achieved when the cover plate 4 is fully closed, avoiding damage to the motor 12 due to stalling, and improving the reliability and service life of the system.

[0022] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
