Description
Technical Field
[0001] This invention relates to the field of charging pile technology, and in particular to a highly safe charging pile. Background Technology
[0002] With the increasing popularity of new energy vehicles, the safety and reliability of charging stations, as a core supporting facility, have become a major concern. Traditional charging stations typically expose the charging gun head directly on the surface of the station or suspend it on an external bracket, which presents the following safety hazards and usage defects:
[0003] Environmental exposure risks: The charging gun head is exposed to the outdoor environment for a long time, and is susceptible to rain erosion, dust accumulation and ultraviolet aging, which can lead to a decrease in insulation performance and oxidation of contacts, and thus cause short circuit or leakage accidents.
[0004] Potential risks of accidental contact and theft: The external nozzle may be plugged in or unplugged by unauthorized personnel, especially in open environments such as public parking lots, which could easily cause equipment damage or theft of electricity.
[0005] To address the aforementioned issues, some improvement solutions attempt to add protective covers or folding brackets to shield the charging nozzle, but these still have significant limitations. For example, some solutions use sliding doors to cover the charging interface, but their mechanical structure is complex, prone to jamming with frequent opening and closing, and lacks integrated power linkage control functions; other solutions use gravity sensors to determine whether the nozzle is in place, but this cannot physically isolate it from environmental intrusion, and may misjudge the connection status in strong vibration scenarios, while also incurring high costs.
[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] To address the technical problems mentioned in the background section, this invention provides a highly secure charging pile.
[0008] The present invention is achieved by the following technical solution: a high-safety charging pile, including a pile body, the front panel of the pile body is detachably connected to the main body of the pile body, a notch is opened on the front panel, a rotating plate is movably installed at the notch, the front of the rotating plate is used to fix the charging gun head, and the cable mechanism connecting the charging gun head passes through the front panel and enters the pile body.
[0009] The bottom of the inner wall of the notch is equipped with a rotary drive mechanism that drives the rotating plate to rotate, so that the charging gun head is located in the charging pile 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, as well as a connecting mechanism connecting the upper plate and the lower plate. The rotation drive mechanism is located at the bottom of the notch. In the early stage of operation, the rotation drive mechanism enables the lower plate and the upper plate to move downward as a whole while rotating relative to each other. In the later stage of operation, the rotation drive mechanism enables the upper plate and the lower plate to rotate synchronously.
[0011] When the charging station is not in use, the rotating plate rotates so that the side with the charging gun head is inside the station, which can effectively provide protection. Furthermore, as it rotates, when the charging gun head is inside the station, its power can be cut off, making it safer.
[0012] As a further improvement to the above solution, the cable mechanism includes a sleeve fixed to the top of the rotating plate, a connector one and a connector two movably located in the sleeve, one end of connector one being connected to cable one, one end of connector two being connected to cable two, the end of cable two being connected to the charging gun head, and the end of cable one being connected to the power source.
[0013] The detachable connectors 1 and 2 facilitate circuit switching and prevent cable twisting caused by the rotating plate, thus ensuring the cable's lifespan.
[0014] As a further improvement to the above solution, a rotating groove is provided inside the front panel, and the sleeve and the rotating groove are rotatably connected. A cover that communicates with the inside of the sleeve is fixed on the outside of the sleeve, allowing the second cable to pass through the cover. This facilitates cable routing and makes the wiring neater.
[0015] As a further improvement to the above solution, the connecting mechanism includes a connecting shaft. A rotary groove is provided on the bottom surface of the upper plate, and a spring is installed in the rotary groove. The bottom of the rotary groove is slidably connected to the connecting shaft along its axial direction. The top end of the connecting shaft abuts against the bottom end of the spring. The bottom end of the connecting shaft is movably located in an annular groove provided on the lower plate. Two arc-shaped movable sections are provided in the annular groove. Two protrusions are symmetrically fixed at 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 sections are connected by a return spring. A retaining ring is also fixed at the opening of the annular groove.
[0016] The above solution allows the upper and lower plates to rotate relative to each other within a certain range. This makes disassembly easier when joint one and joint two are separated, as they first move away from each other before rotating relative to each other.
[0017] As a further improvement to the above design, an operating gap is provided between the upper and lower plates;
[0018] The retaining ring is detachably connected to the annular groove, and the top of the annular groove has a larger aperture recess in which a positioning unit for positioning the retaining ring is installed.
[0019] Two sets of positioning units are symmetrically arranged, and each positioning unit includes an abutment rod rotatably connected inside the sink. The bottom section of the abutment rod can abut against the top surface of the retaining ring, and the top section of the abutment rod is located in the operating gap.
[0020] The above structure allows for easy installation and disassembly, making operation faster.
[0021] As a further improvement to the above solution, the inner wall of the settling tank is provided with a slot corresponding to the positioning unit, and a magnet is installed in the slot. A magnetic layer is provided in the middle of the contact rod to attract the magnet. This facilitates the installation and replacement of the magnet.
[0022] As a further improvement to 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 fixed to the bottom surface of the lower plate. The bottom surface of the pin is provided with a pin groove. The motor shaft of the rotary motor and the pin groove are axially slidably connected. A spiral guide groove is also provided on the inner wall of the connecting groove. A guide block that cooperates with the guide groove is fixed on the outer wall of the pin.
[0023] The spiral guide grooves described above allow the rotating plate to move vertically, facilitating the separation of the two joints.
[0024] As a further improvement to the above solution, a bayonet is provided on the panel that communicates with the rotating groove. A second movable block is detachably installed at the bayonet. The inner side of the second movable block has a concave surface, and the concave surface is coplanar with the annular inner wall of the rotating groove.
[0025] This facilitates the installation of cable one and cable two, the installation of connector one and connector two, and the replacement of parts during later maintenance.
[0026] As a further improvement to the above scheme, several unit pressure rings are also movably installed in the rotating groove. The unit pressure rings are movably sleeved on the outside of the first cable and pressed on the top of the first connector. A crossbar is fixed on the concave surface of the second movable block. When the second movable block and the bayonet are connected and installed, the crossbar is pressed tightly on the top surface of the uppermost unit pressure ring.
[0027] The crossbar effectively applies pressure to the connector, preventing it from shifting.
[0028] As a further improvement to the above scheme, a U-shaped inner protective plate is also installed inside the pile body. The inner protective plate is used to separate the front panel from other structures inside the pile body. A first movable block that cooperates with the rotating groove is detachably installed on the top of the front panel. Both the first movable block and the inner protective plate are provided with wire holes to facilitate the passage of cables.
[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0030] This invention features a rotatable rotating plate on the front panel of the charging pile. The rotating plate is a split design, consisting of an upper plate and a lower plate. The charging gun head is fixed to the rotating plate using a fixed bracket or gun slot. When not in use, the rotating plate can be rotated to position the charging gun head within the charging pile body, providing good protection. Furthermore, when the charging gun head is rotated and positioned within the charging pile body, the current to the cable structure can be automatically cut off, enhancing safety. When the charging pile needs to be used, the rotating plate rotates to position the charging gun head on the outside, at which point the disconnected connectors one and two in the cable can be reconnected to restore current, facilitating use.

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example
[0043] Reference Figures 1-9 This solution proposes a high-safety charging pile, including a pile body 1. The front panel 4 of the pile body 1 is detachably connected to the main body of the pile body 1. A notch 20 is provided on the front panel 4. The notch can be rectangular. A protective bristle can be provided on the inner side of the notch 20 to isolate it from the outside. A rotating plate 3 is movably installed at the notch 20. The front of the rotating plate 3 is used to fix the charging gun head 9. The cable mechanism connecting the charging gun head 9 passes through the front panel 4 and enters the pile body 1.
[0044] The bottom of the inner wall of the notch 20 is provided with a rotation drive mechanism that drives the rotating plate 3 to rotate, so that the charging gun head 9 is located inside the pile body 1 when not in use; and the cable mechanism can adapt to the rotation of the rotating plate 3 to ensure that its circuit is cut off or connected.
[0045] The rotating plate 3 includes an upper plate 301 and a lower plate 302 that are movably connected, as well as a connecting mechanism that connects the upper plate 301 and the lower plate 302. The rotation drive mechanism is located at the bottom of the notch 20. In the early stage of operation, the rotation drive mechanism enables the lower plate 302 and the upper plate 301 to move downward as a whole while rotating relative to each other. In the later stage of operation, the rotation drive mechanism enables the upper plate 301 and the lower plate 302 to rotate synchronously.
[0046] Through the above design, this solution allows the rotating plate 3 to rotate so that the side with the charging gun head 9 fixed is inside the pile body 1 when the charging pile is not in use, which can effectively play a protective role. Furthermore, as it rotates, when the charging gun head 9 is inside the pile body, its power can be cut off, making it safer.
[0047] As an optional embodiment of the present invention, the cable mechanism includes a sleeve 18 fixed to the top of the rotating plate 3, a connector 17 and a connector 23 movably located in the sleeve 18, one end of the connector 17 being connected to a cable 10, one end of the connector 23 being connected to a cable 8, the end of the cable 8 being connected to a charging gun head 9, and the end of the cable 10 being connected to a power source.
[0048] The detachable connectors 1 and 2 facilitate circuit switching and prevent the cable from twisting due to the rotation of the rotating plate 3, thus ensuring the cable's service life.
[0049] It should be noted that a rotating groove is provided inside the front panel 4, and the sleeve 18 is rotatably connected to the rotating groove. A cover 19 communicating with the inside is fixed on the outside of the sleeve 18, and the cable 8 can pass through the cover 19. This facilitates cable laying and makes the wiring neater.
[0050] Specifically, the sleeve and the inner wall of the rotating groove can be connected by existing bearings so that the sleeve can rotate in the rotating groove or move axially a certain distance inside it.
[0051] As an optional embodiment of the present invention, see below. Figure 6 and Figure 8 The connecting mechanism includes a connecting shaft 28. A rotary groove (not shown, but this does not affect the understanding of the solution by those skilled in the art) is provided on the bottom surface of the upper plate 301. A spring 29, a columnar spring, is installed in the rotary groove. The bottom of the rotary groove is slidably connected to the connecting shaft 28 along its axial direction. The top end of the connecting shaft 28 abuts against the bottom end of the spring 29. The bottom end of the connecting shaft 28 is movably disposed in an annular groove 40 provided on the lower plate 302. Two arc-shaped movable sections 39 are provided in the annular groove 40. Two protrusions 33 are symmetrically fixed to the bottom end of the connecting shaft 28. The two protrusions 33 are respectively movably located in the two movable sections 39, and the protrusions 33 and the inner walls of the movable sections 39 are connected by a return spring 32. A retaining ring 31 is also fixed at the opening of the annular groove 40. The return spring 32 provides a torsional restoring force.
[0052] The above solution enables the upper plate 301 and the lower plate 302 to rotate relative to each other within a certain range. This allows the two to move away from each other before rotating relative to each other when the first and second joints are separated, making disassembly easier.
[0053] To facilitate installation and disassembly, the upper plate 301 and the lower plate 302 of this solution have an operating gap, the width of which shall not be less than 1cm; the retaining ring 31 is detachably connected to the annular groove 40, and the top of the annular groove has a recess with a larger aperture, in which a positioning unit for positioning the retaining ring 31 is installed.
[0054] Two sets of positioning units are symmetrically arranged, and each positioning unit includes an abutment rod rotatably connected inside the sink. The bottom section 36 of the abutment rod can abut against the top surface of the retaining ring 31, and the top section 35 of the abutment rod is located in the operating gap, which facilitates installation and disassembly and makes operation faster.
[0055] It should be noted that in this embodiment, the inner wall of the settling tank has a slot 34 corresponding to the positioning unit, and a magnet 30 is installed in the slot 34. A magnetic layer, attracted to the magnet 30, is provided in the middle of the abutment rod. This facilitates the installation and replacement of the magnet. Figure 6 As shown, the magnet attracts the contact rod, causing its bottom section 36 to press against the top of the retaining ring 31, thereby fixing the position of the retaining ring and the connecting shaft 28.
[0056] In this plan, you can refer to Figure 7 and Figure 9 The rotary drive mechanism includes an installation groove 24 opened in the pile body 1, a rotary motor 21 located in the installation groove 24, and a pin 38 fixed on the bottom surface of the lower plate 302. The bottom surface of the pin 38 is provided with a pin groove 41. The motor shaft 25 of the rotary motor 21 and the pin groove 41 are axially slidably connected. The inner wall of the connecting groove 37 is also provided with a spiral guide groove 27. The outer wall of the pin 38 is fixed with a guide block 26 that cooperates with the guide groove 27.
[0057] The present invention enables the rotating plate 3 to move vertically through the spiral guide groove 27, so as to facilitate the separation of the two joints.
[0058] Please refer to Figure 4 As a further improvement to the above solution, panel 4 has a bayonet that communicates with the rotating groove. A second movable block 12 is detachably installed at the bayonet. The inner side of the second movable block 12 has a concave surface 14, and the concave surface 14 is coplanar with the annular inner wall of the rotating groove. Specifically, the inner wall of the rotating groove has a docking platform 11 that mates with the second movable block 12. The docking platform 11 has a docking hole 15, and the second movable block 12 has a through hole 13 corresponding to the docking hole 15. In this way, the second movable block 12 can be installed and removed by bolts.
[0059] To facilitate the installation of cable one and cable two, to make it easier to install connector one and connector two, and to facilitate the replacement of parts during later maintenance.
[0060] To ensure more stable and reliable operation, several unit pressure rings 16 are movably installed inside the rotating groove. These unit pressure rings 16 are movably sleeved on the outside of cable 10 and press against the top of connector 17. A crossbar (not shown in the figure, see reference) is fixed on the concave surface 14 of the second movable block 12. Figure 4Its structure on the concave surface is not shown. There may be two crossbars, located on both sides of cable 10 respectively. After the second movable block 12 and the bayonet are installed, the two crossbars are pressed against the top surface of the uppermost unit pressure ring 16.
[0061] The two crossbars can effectively apply pressure to connector 17, preventing it from shifting.
[0062] Reference Figure 1 The pile body is also equipped with a U-shaped inner protective plate 2, which is used to separate the front panel 4 from other internal structures of the pile body 1. A first movable block 5 that cooperates with the rotating groove is detachably installed on the top of the front panel 4. Both the first movable block 5 and the inner protective plate 2 are provided with wire holes 6 to facilitate the passage of cable 10. The edge of the inner protective plate 2 has a flange 7, and threaded holes can be opened on the flange 7 so as to fix it to the main body of the pile body 1 through the flange. The front panel and the inner protective plate 2 can also be connected by detachable screws or bolts.
[0063] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
