Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with high safety. Background Art

[0002] With the popularity of new energy vehicles, charging piles, as core supporting facilities, have attracted much attention for their safety and reliability. Traditional charging piles usually expose the charging gun head directly on the surface of the pile or hang it on an external bracket, which has the following safety hazards and usage defects:

[0003] Environmental exposure risk: The charging gun head is exposed to the outdoor environment for a long time, which is susceptible to rain erosion, dust accumulation and ultraviolet aging, resulting in reduced insulation performance and contact oxidation, which in turn causes short circuit or leakage accidents;

[0004] Hidden dangers of accidental touch and misappropriation: The external gun head may be plugged in and out at will by unauthorized personnel, especially in open scenes such as public parking lots, which may easily cause equipment damage or power theft.

[0005] In response to the above problems, some improvement plans have tried to add a protective cover or folding bracket to cover the gun head, but there are still obvious limitations. For example, some solutions use a sliding door to cover the charging port, but its mechanical structure is complex, it is easy to get stuck when opened and closed frequently, and it does not integrate the power linkage control function; other solutions use gravity sensing to determine whether the gun head has returned to its position, but it cannot physically isolate the environment from intrusion, and may misjudge the connection status in strong vibration scenarios, which is costly.

[0006] Therefore, how to achieve integrated control of storage space and electrical safety has become a key technical bottleneck in improving the safety level of charging piles. Summary of the invention

[0007] In order to solve the technical problems raised in the background technology, the present invention provides a charging pile with high safety.

[0008] The present invention is implemented by the following technical scheme: a charging pile with high safety, including a pile body, a front panel of the pile body being detachably connected to its main body, a notch being provided on the front panel, a rotating plate being movably installed at the notch, the front side of the rotating plate being used to fix a charging gun head, and a cable mechanism connecting the charging gun head being inserted into the pile body through the front panel.

[0009] A rotating drive mechanism for driving the rotating plate to rotate is provided at the bottom of the inner wall of the notch, so that the charging gun head can be located in the pile body when not in use; and the cable mechanism can adapt to the rotation of the rotating plate to ensure that its circuit is cut off or connected.

[0010] The rotating plate includes an upper plate and a lower plate that are movably connected, and a connecting mechanism connecting the upper plate and the lower plate. The rotating drive mechanism is arranged at the bottom of the notch. In the early stage of the operation of the rotating drive mechanism, the lower plate and the upper plate can move downward as a whole while rotating relative to each other. In the later stage of the operation of the rotating drive mechanism, the upper plate and the lower plate can rotate synchronously.

[0011] In this way, when the charging pile is not in use, the rotating plate rotates so that the side where the charging gun head is fixed is located inside the pile body, which can effectively play a protective role. Moreover, as the charging gun head rotates, when it is located inside the pile body, its power supply can be cut off, which is safer.

[0012] As a further improvement of the above scheme, the cable mechanism includes a sleeve fixed to the top of the rotating plate, connector 1 and connector 2 movably located in the sleeve, one end of connector 1 is connected to cable 1, one end of connector 2 is connected to cable 2, the end of cable 2 is connected to the charging gun head, and the end of cable 1 is connected to the power supply.

[0013] The detachable connector 1 and connector 2 can facilitate the on-off of the circuit on the one hand, and can prevent the cable from being twisted by the rotation of the rotating plate on the other hand, thereby ensuring the service life of the cable.

[0014] As a further improvement of the above solution, a rotation groove is provided in the front panel, the sleeve and the rotation groove are rotationally connected, and a cover connected to the inside of the sleeve is fixed on the outside of the sleeve, and the cable 2 can pass through the cover, which is convenient for laying cables and makes the lines more neat.

[0015] As a further improvement of the above scheme, the connecting mechanism includes a connecting shaft, a rotating groove is opened on the bottom surface of the upper plate, a spring is installed in the rotating groove, the bottom of the rotating groove is connected to the connecting shaft along its axial sliding, the top of the connecting shaft and the bottom of the spring are in contact, the bottom end of the connecting shaft is movably arranged in an annular groove opened on the lower plate, two arc-shaped movable sections are arranged in the annular groove, two protrusions are symmetrically fixed to the bottom end of the connecting shaft, the two protrusions are respectively movably located in the two movable sections, and the protrusions and the inner wall of the movable section are connected by a return spring, and a retaining ring is also fixed at the notch of the annular groove.

[0016] The above scheme enables the upper plate and the lower plate to rotate relative to each other within a certain range, so that when the joint 1 and the joint 2 are separated, the two can be moved away from each other first and then rotate relative to each other, making disassembly more convenient.

[0017] As a further improvement of the above solution, there is an operating gap between the upper plate and the lower plate;

[0018] The retaining ring is detachably connected to the annular groove, and the top of the annular groove is provided with a sink groove with a larger aperture, in which a positioning unit for positioning the retaining ring is installed;

[0019] Two groups of positioning units are symmetrically arranged, and the positioning units include a resistance rod rotatably connected to the inside of the sink, the bottom section of the resistance rod can resist the top surface of the retaining ring, and the top section of the resistance rod is located in the operating gap.

[0020] The above structure can facilitate installation and disassembly, and the operation is faster.

[0021] As a further improvement of the above solution, a slot corresponding to the positioning unit is provided on the inner wall of the sink, a magnet is installed in the slot, and a magnetic layer that is magnetically attracted to the magnet is provided in the middle of the abutment rod, so as to facilitate the installation and replacement of the magnet.

[0022] As a further improvement of the above scheme, the rotary drive mechanism includes an installation groove opened in the pile body, a rotary motor located in the installation groove and a pin shaft fixed to the bottom surface of the lower plate, the bottom surface of the pin shaft is provided with a pin groove, the motor shaft of the rotary motor and the pin groove are axially relatively slidably connected, the inner wall of the connecting groove is also provided with a spiral guide groove, and the outer wall of the pin shaft is fixed with a guide block that cooperates with the guide groove.

[0023] The spiral guide groove 27 can enable the rotating plate 3 to move vertically so as to separate the two joints.

[0024] As a further improvement of the above solution, a bayonet connected to the rotating groove is provided on the panel 4, and a movable block 12 is detachably installed at the bayonet. The inner side of the movable block 12 has a concave surface 14, and the concave surface 14 is coplanar with the annular inner wall of the rotating groove.

[0025] This facilitates the routing of cable one and cable two, the installation of connector one and connector two, and the subsequent maintenance and replacement of parts.

[0026] As a further improvement of the above scheme, a plurality of unit pressure rings 16 are movably arranged in the rotating groove. The unit pressure ring 16 is movably sleeved on the outside of the cable 10 and pressed above the connector 17. A cross bar is fixed on the concave surface 14 of the movable block 12. When the movable block 12 and the bayonet are docked and installed, the cross bar is pressed against the top surface of the uppermost unit pressure ring 16.

[0027] Through the cross bar, a certain pressure can be effectively applied to the joint 17 to prevent its position from moving.

[0028] As a further improvement of the above scheme, a U-shaped inner guard plate 2 is also installed in the pile body, and the inner guard plate 2 is used to separate the front panel 4 and other structures inside the pile body 1. A movable block 5 that cooperates with the rotating groove is detachably installed on the top of the front panel 4, and a threading hole 6 is provided on the movable block 5 and the inner guard plate 2 to facilitate the passage of the cable 10.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention provides a rotatable rotating plate on the front panel of the charging pile. The rotating plate adopts a split design and is composed of an upper plate and a lower plate. The charging gun head is fixed to the rotating plate by a fixed bracket or a gun groove. The rotating plate can be rotated when not in use, so that the rotating plate carrying the charging gun head is located in the pile body, which plays a good protective role. When the charging gun head is rotated and located in the pile body, the current of the cable structure can be automatically cut off, which has higher safety. When the charging pile needs to be used, the rotating plate is rotated so that the charging gun head is located on the outside. At this time, connectors one and two in the cut-off cable can be re-inserted to connect the current, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS
