Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and in particular relates to a portable charging pile supporting structure. Background Art

[0002] Charging piles are usually divided into fixed charging piles and mobile charging piles. 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. Mobile charging piles can be flexibly moved, providing convenience during use.

[0003] For example, Chinese utility model CN209719302U discloses a portable charging pile. A handle is provided on the top of the charging pile body, which is connected to the charging pile body by screws. Rollers are symmetrically provided on the bottom of the charging pile body, and the rollers are installed by screw connections. This structure facilitates the movement of the device.

[0004] However, in the above-mentioned prior art, the flexible movement of the charging pile is achieved by installing rollers. However, due to the installation of the rollers, the fixing effect of the charging pile itself is poor. For example, when the ground is uneven or when the wind is strong outdoors, the charging pile is very likely to change position, which can easily pull the wires, affecting charging or causing damage to the wires.

[0027] Embodiment 1

[0028] See also Figures 1 to 3As shown, the utility model is a portable charging pile support structure, including a charging pile body 1, two pairs of universal rollers 2 are installed at the bottom of the charging pile body 1, a push rod 3 is slidably connected to the bottom of the charging pile body 1, and the push rod 3 and the charging pile body 1 can be connected through a slide rail.

[0029] like Figure 4 and 5 As shown, or by opening two strip-shaped slots 304 in the push rod 3 along the length direction, the bottom of the charging pile body 1 is threadedly connected with a limit screw 305 that is in clearance with the strip slot 304, so that the push rod 3 can only move along the length direction, and a sliding connection is realized between the push rod 3 and the charging pile body 1. Among them, the limit screw 305 is sleeved with a bushing, and the outer wall of the bushing is in clearance with the strip slot 304. By adding the bushing, the wear on the screw can be reduced, which is convenient for subsequent replacement and maintenance.

[0030] The push rod 3 is located between two universal rollers 2 of one pair, one end of the push rod 3 extends to the outside of the charging pile body 1, and a pull handle 306 is fixedly connected to the end of the push rod 3.

[0031] The other end is vertically connected with a push plate 301, and both ends of the push plate 301 are provided with straight slots 302. The push plate 301 and the push rod 3 can be welded or formed into an integrated plate structure.

[0032] The two universal rollers 2 in a pair are connected to a lever 201 on one side close to the push rod 3, and the two levers 201 are respectively connected to pins 202 that cooperate with the straight slots 302 at both ends of the push plate 301, which are used to push and pull the push rod 3, and use the push plate 301 and the lever 201 to drive the two universal rollers 2 to rotate, so that the two universal rollers 2 can switch between being parallel to each other and forming an eight-shaped state with each other.

[0033] Specifically, Figure 2 and 5 As shown, when the two universal rollers 2 are in parallel, the charging pile body 1 can be flexibly moved. When the charging pile body 1 needs to be kept in a fixed position, the push rod 3 can be pushed by pulling the handle 306. At this time, the push plate 301 pushes the levers 201 on the universal rollers 2 on both sides through the pin 202, so that the two universal rollers 2 rotate in opposite directions.

[0034] like Figure 6 As shown, after the two universal rollers 2 rotate in opposite directions, the two universal rollers 2 rotate in an eight-shaped shape relative to each other, so that the charging pile body 1 cannot be moved by the universal rollers 2, so that the charging pile body 1 can maintain a fixed position, avoiding pulling on the wires, and ensuring the reliability of charging and the service life of the wires.

[0035] Embodiment 2

[0036] Based on the first embodiment, Figure 4 and 5 As shown, the bottom of the charging pile body 1 is threadedly connected or integrally formed with a connecting column 101 located on the side of the push rod 3, the connecting column 101 is sleeved with a torsion spring 102, and is rotatably connected to a strip plate 103, and the end of the strip plate 103 is connected to a follower roller 104.

[0037] The torsion spring 102 is connected to the strip plate 103, and is used to drive the strip plate 103 through the torsion spring 102, so that the follower roller 104 moves toward the push rod 3. A limiting notch 303 is provided on the side of the push rod 3, and the follower roller 104 cooperates with the limiting notch 303 to limit the position of the push rod 3, and when the push rod 3 is pushed to move, so that the limiting notch 303 cooperates with the follower roller 104, the corresponding two universal rollers 2 are in an eight-shaped state with each other, and the follower roller 104 is stuck in the limiting notch 303, thereby limiting the movement of the push rod 3, so that the position of the push rod 3 to be adjusted can be more accurately known, and the two universal rollers 2 can maintain the adjusted position state to ensure the overall reliability.

[0038] When it is necessary to move, the push rod 3 is directly pulled to squeeze and push the follower roller 104, so that the strip plate 103 rotates and the follower roller 104 slides out of the limit slot 303. Another limit slot 303 is opened on the side of the push rod 3, and when the push rod 3 is pulled so that the other limit slot 303 cooperates with the follower roller 104, the corresponding two universal rollers 2 are in a state of being parallel to each other, as shown in FIG. Figure 5 As shown, after the follower roller 104 is inserted into another limiting slot 303 , the push rod 3 is moved to a certain position, so that the two universal rollers 2 remain parallel to each other, which facilitates the position movement of the charging pile body 1 .

[0039] At the same time, in order to improve the effect of limiting the position of the push rod 3, connecting columns 101, torsion springs 102, strip plates 103 and follower rollers 104 can be set on both sides of the push rod 3, and two limiting slots 303 are also opened on the other side of the push rod 3. The follower rollers 104 on both sides cooperate with the limiting slots 303 to further limit the position of the push rod 3, thereby improving the overall reliability and stability of use.
