Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging equipment technology, specifically a mobile charging device. Background Technology

[0002] Charging piles can be divided into public charging piles and dedicated charging piles according to their installation location. Public charging piles are built in public parking lots and parking spaces to provide public charging services for vehicles. Dedicated charging piles are built in parking lots owned by the building unit and are used by the unit's internal staff. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] With the rapid development of the new energy vehicle industry, the demand for charging equipment, as a key infrastructure to ensure vehicle range, is increasing daily. However, while existing mobile charging equipment has a certain degree of mobility thanks to casters, it lacks an efficient and stable method of fixing itself in place once it reaches the designated location. Some devices rely solely on the caster's brakes, making them prone to displacement and tipping under external forces such as vehicle entry / exit or pedestrian movement. This not only affects the continuity and safety of the charging process but may also damage the charging interface and cause electrical faults due to equipment shaking. Therefore, those skilled in the art have provided a mobile charging device to solve the problems mentioned in the background art. Utility Model Content

Flexible Deployment and Stable Fixation: Equipped with casters, this device can be easily pushed to any desired location, adapting to different charging scenarios (such as different areas of a parking lot, temporary outdoor charging points, etc.). It eliminates the need for complex handling tools, greatly improving the flexibility of device deployment. At the same time, through the coordinated operation of servo motors, threaded rods, sliders, and lifting frames, this device can quickly lower the lifting frame to the ground. Combined with a retractable movable plate, it increases the contact area with the ground, effectively enhancing the stability of the device and preventing it from tipping over due to external forces (such as vehicle scratches or collisions with people) during charging, ensuring charging safety and the integrity of the device.

[0013] 2. Reduce space occupation: The lifting frame, moving plate and other components can be stored in the storage slot at the bottom of the charging equipment body. When not in use, they do not take up extra space, making the equipment look simple and neat.

[0014] 3. Anti-tipping reinforcement: The movable plate can expand the support range in both front and rear directions, significantly reducing the risk of the equipment tipping over; and the sliding connection between the movable plate and the lifting frame, and the cooperation between the protruding plate and the sliding rod, prevent the movable plate from falling off while expanding the support, thus building a solid safety barrier from the structural level.

[0023] The working principle of this utility model is as follows: First, the charging device can be moved to a designated position using the casters 4. Then, the servo motor 7 is started to drive the threaded rod 8 to rotate. The threaded rod 8 drives the slider 10 to move downwards along the slide groove 6. The slider 10 drives the lifting frame 9 downwards to contact the ground, thus fixing the charging device in the designated position. Finally, the push-pull groove 19 on the moving plate 13 is pulled outwards, causing the front and rear moving plates 13 to move forward and backward respectively. This extends the distance between the front and rear bottom of the lifting frame 9, thereby lowering the charging device. The protruding plate 14 is slidably connected to the slide rod 12 to prevent the moving plate 13 from detaching from the lifting frame 9. When repositioning is required, firstly, push the moving plate 13 inward to move the two moving plates 13 towards the middle, and then retract the moving plate 13 into the lifting frame 9. Then, start the servo motor 7 to make the threaded rod 8 drive the slider 10 to move upward. The slider 10 drives the lifting frame 9 to move upward into the storage slot 18, thus releasing the locking of the lifting frame 9 to the charging device. Finally, the universal wheel 4 can be used to push the charging device to a new usage position.
