DETAILED DESCRIPTION In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 11, which is the first embodiment of the present invention, proposes a high-low voltage switching electric vehicle charging pile, including a shell 1, the shell 1 has a first cavity 101 inside; the whole line board 2 is arranged in the first cavity 101, and one end of the charging line 3 is arranged on the whole line board 2; the sliding steering block 4 is slidably arranged on the whole line board 2, the charging line 3 is wound around the sliding steering block 4, and the other end of the charging line 3 is connected to the first charging gun 5. After the first charging gun 5 moves away from or approaches the shell 1, the sliding steering block 4 slides; the two ends of the first elastic member 6 act on the sliding steering block 4 and the whole line board 2 respectively, and the first elastic member 6 is used to provide a force for resetting the sliding steering block 4.

[0024] In this embodiment, in order to solve the problem that the electric wires of the electric vehicle charging pile are exposed and often rubbed against the ground and easily damaged in the related art, a high-low voltage switching electric vehicle charging pile is designed, and its core components are located in the shell 1. There is a first cavity 101 in the shell 1, and a line board 2 is arranged in this cavity. One end of the charging line 3 is fixed on the line board 2, the middle part is wound on the sliding steering block 4, and the other end is connected to the first charging gun 5. The sliding steering block 4 can slide smoothly on the line board 2. For example, when the user unplugs the first charging gun 5 from the electric car and keeps it away from the shell 1, the charging line 3 will drive the sliding steering block 4 to slide on the line board 2. When the first charging gun 5 is close to the shell 1 after use, the first elastic member 6 will play a role. The two ends of the first elastic member 6 are respectively against the sliding steering block 4 and the line board 2, which will provide a reset force for the sliding steering block 4, so that the charging line 3 is restored to the initial state, which is convenient for the next use.

[0025] The advantage is that this design manages the expansion and contraction of the charging cable 3 through the cooperation of the sliding steering block 4 and the line board 2, avoiding its messy placement and facilitating user use and storage. At the same time, during the movement of the charging gun, the sliding of the sliding steering block 4 can reduce the pulling and friction of the charging cable 3, reduce the possibility of damage, and extend the service life. Moreover, the first elastic member 6 ensures that the charging cable 3 can be automatically reset when the charging gun is returned to its position, which improves the convenience of use and the overall aesthetics of the charging pile.

[0026] Furthermore, the side wall of the shell 1 has a plurality of grooves 102, and the charging cable 3 has a magnetic plug 301 at one end away from the whole line board 2, and also includes a second charging gun 7. The second charging gun 7 and the first charging gun 5 are respectively vertically arranged in different grooves 102, and the first charging gun 5 and the second charging gun 7 have a charging head 501 at one end and a magnetic socket 502 at the other end; the sliding frame 8 is slidably arranged in the first cavity 101, and the magnetic plug 301 is plugged into the sliding frame 8. After the sliding frame 8 slides, the sliding frame 8 is close to the first charging gun 5 or the second charging gun 7. After the magnetic plug 301 moves, the magnetic plug 301 is plugged or unplugged from the magnetic socket 502.

[0027] In this embodiment, a plurality of grooves 102 are provided on the side wall of the housing 1. The end of the charging cable 3 away from the whole line board 2 is equipped with a magnetic plug 301. The charging pile also includes a first charging gun 5 and a second charging gun 7, which are vertically placed in different grooves 102. The first charging gun 5 and the second charging gun 7 have a charging head 501 at one end and a magnetic socket 502 at the other end. A sliding frame 8 is also provided in the first cavity 101, and a first slideway 801 is provided on the sliding frame 8, and the magnetic plug 301 can slide in the first slideway 801. When charging with different voltages is required, the sliding frame 8 slides to make it close to the corresponding charging gun (the first charging gun 5 or the second charging gun 7), and the magnetic plug 301 is plugged or unplugged with the corresponding magnetic socket 502 during the sliding process. For example, when the vehicle needs high-voltage charging, the sliding frame 8 moves to plug the magnetic plug 301 with the magnetic socket 502 of the second charging gun 7.

[0028] The advantage is that, through the cooperation of the sliding frame 8 and the magnetic plug 301 with different charging guns, convenient switching between high and low voltage charging is achieved, meeting the charging needs of different electric vehicles. According to the voltage to be charged, the corresponding position is selected on the operating platform in advance, and the sliding frame 8 will slide under the corresponding charging gun. This design integrates charging guns of different voltages into the charging pile, and uses the groove 102 design to make the charging pile compact. While saving installation space, it can also prevent the charging gun from being exposed to rain and achieve a waterproof effect. In addition, the connection method between the magnetic plug 301 and the magnetic socket 502 is safer and more reliable than the traditional plug-in method, and can effectively prevent safety hazards such as electric sparks during the plug-in process.

[0029] Furthermore, the magnetic plug 301 has an abutment portion 3011 and also includes a traction sleeve 9, which is slidably set on the sliding frame 8. The traction sleeve 9 has a traction portion 901, and the abutment portion 3011 abuts against the traction sleeve 9. The magnetic plug 301 is inserted into the sliding frame 8 through the traction sleeve 9; the sliding member 10 is slidably set in the sliding frame 8 and is used to abut against the traction portion 901. After the sliding member 10 slides, it drives the traction sleeve 9 to slide.

[0030] In this embodiment, the magnetic plug 301 has an abutment portion 3011, and the charging pile further includes a traction sleeve 9 and a sliding member 10. The traction sleeve 9 has a traction portion 901, and the abutment portion 3011 is tightly abutted with the traction sleeve 9, so that the magnetic plug 301 slides in the first slideway 801 through the traction sleeve 9. The sliding member 10 slides in the sliding frame 8 and abuts against the traction portion 901. When it is necessary to control the sliding of the magnetic plug 301, the sliding member 10 is operated to slide, and the sliding member 10 drives the traction sleeve 9 to slide through the traction portion 901, thereby driving the magnetic plug 301 to move in the first slideway 801.

[0031] The advantage is that this structure can more accurately control the sliding position of the magnetic plug 301 through the transmission of the sliding member 10 and the traction sleeve 9, ensuring that it is accurately plugged in or separated from the magnetic socket 502 of the charging gun, thereby improving the reliability of the charging system. At the same time, it makes the sliding process of the magnetic plug 301 more stable, reduces the shaking or misalignment of the plug caused by external interference, and ensures the stability of the charging connection. Moreover, this design is easy to combine with an automated control system, and realizes the automated operation of the charging process by controlling the movement of the sliding member 10, thereby improving the intelligence level of the charging pile.

[0032] Furthermore, it also includes a flip door 11, which has a plurality of flip doors 11, and the plurality of flip doors 11 are rotatably arranged on the shell body 1, and are used to close or unseal the groove 102 after being flipped; one end of the first traction rope 12 is relatively connected to the flip door 11, and the other end of the first traction rope 12 has a limiting claw 1201, and the limiting claw 1201 has a limiting space, and the limiting claw 1201 is located in the first cavity 101. After the flip door 11 is flipped, the first traction rope 12 is driven to move; one end of the second traction rope 13 is connected to the sliding member 10, and the other end has a first ball head 1301, and the first ball head 1301 is located in the first cavity 101. After the sliding frame 8 slides horizontally, the first ball head 1301 enters the limiting space. After the first traction rope 12 moves, the limiting claw 1201 slides vertically, driving the second traction rope 13 to move, so that the sliding member 10 slides.

[0033] In this embodiment, the charging pile includes a plurality of flip doors 11, which are rotatably mounted on the housing 1 and are respectively located at the groove edges of a plurality of grooves 102. When the flip door 11 flips, the groove 102 can be closed or unsealed. One end of the first traction rope 12 is relatively connected to the flip door 11, and the other end has a limit claw 1201 with a limited space, and the limit claw 1201 is located in the first cavity 101. When the flip door 11 flips, it will drive the first traction rope 12 to move. At the same time, there is also a second traction rope 13, one end of which is connected to the sliding member 10, and the other end has a first ball head 1301, and the first ball head 1301 is also in the first cavity 101. When the sliding frame 8 slides to a suitable position, the first ball head 1301 will enter the limit space of the limit claw 1201. Afterwards, when the flip door 11 flips and drives the first traction rope 12 to move, it will pull the second traction rope 13 to move, thereby causing the sliding member 10 to slide. For example, in the process of opening or closing the flip door 11 , the sliding member 10 is controlled through the linkage mechanism, thereby controlling the plugging state of the magnetic plug 301 .

[0034] The advantage is that, through the linkage design of the flip door 11, the first traction rope 12 and the second traction rope 13, the door opening operation is linked to the charging gun connection operation, which realizes convenient integrated operation and improves the convenience of user use. When the flip door 11 closes the groove 102, it can prevent raindrops, dust, debris, etc. from entering the charging gun storage area. At the same time, it can also prevent people from accidentally touching the charging gun during the charging process, thereby improving the safety of the charging pile. Moreover, the use of mechanical linkage eliminates the need for complex electronic control equipment, making the structure of the entire charging pile more compact, reducing costs and failure rates.

[0035] Furthermore, a second elastic member 14 is included. Two ends of the second elastic member 14 are respectively connected to the sliding member 10 and the sliding frame 8 to provide a force for restoring the sliding member 10 .

[0036] In this embodiment, in the charging pile, the two ends of the second elastic member 14 are connected to the sliding member 10 and the sliding frame 8 respectively. When the sliding member 10 moves under the action of external force, the second elastic member 14 will undergo elastic deformation. For example, when the first traction rope 12 pulls the sliding member 10 to move through the second traction rope 13, the second elastic member 14 is stretched. When the external force disappears, the second elastic member 14 will use its own elastic restoring force to provide a reset force for the sliding member 10, so that the sliding member 10 returns to the initial position.

[0037] The advantage is that the second elastic member 14 can ensure that the sliding member 10 can automatically reset after the operation is completed, so that the entire charging system returns to the initial state and is ready for the next charging operation. It can reduce the possibility of the sliding member 10 position shifting due to external factors (such as vibration, etc.), and improve the stability and reliability of the charging system. In addition, it can also avoid the wear or damage of the sliding member 10 caused by being in an unnatural state for a long time, and extend the service life of the sliding member 10.

[0038] Furthermore, the inner wall of the groove 102 has a second slideway 1021 , and the limiting claw 1201 enters the first cavity 101 through the second slideway 1021 .

[0039] In this embodiment, a second slideway 1021 is designed on the inner wall of the groove 102 of the charging pile, and the limiting claw 1201 enters the first cavity 101 through the second slideway 1021. When the flip door 11 flips to drive the first traction rope 12 to move, the limiting claw 1201 slides smoothly between the inner wall of the groove 102 and the first cavity 101 along the second slideway 1021. For example, the surface of the second slideway 1021 is smooth, and its size matches the shape of the limiting claw 1201, ensuring that the limiting claw 1201 will not get stuck or fall off the track during the sliding process.

[0040] The advantage is that the second slideway 1021 provides a stable motion track for the limiting claw 1201, so that it can slide smoothly between the groove 102 and the first cavity 101, ensuring the normal operation of the first traction rope 12, and then ensuring the smooth linkage operation of the entire charging system. It can prevent the limiting claw 1201 from deflecting or shaking during the movement, avoid damage to the first traction rope 12 or charging system failure caused by abnormal movement of the limiting claw 1201, and improve the stability of the charging pile structure. At the same time, this design facilitates the installation and positioning of the limiting claw 1201, and it is also easier to check and repair possible problems during later maintenance.

[0041] Furthermore, the inner wall of the groove 102 also has a slide groove 1022, and the first traction rope 12 has a second ball head 1202 at one end close to the flip door 11, and the second ball head 1202 is slidably set in the slide groove 1022. It also includes a connecting rod 15, one end of the connecting rod 15 is hinged to the flip door 11, and the other end is slidably set in the slide groove 1022. After the flip door 11 rotates, the other end of the connecting rod 15 is driven to slide in the slide groove 1022, so that the other end of the connecting rod 15 is abutted or released from the abutment with the second ball head 1202, driving the second ball head 1202 to slide in the slide groove 1022, so that the first traction rope 12 moves.

[0042] In this embodiment, in addition to the second slide 1021, there is also a slide groove 1022 on the inner wall of the groove 102. The first traction rope 12 has a second ball head 1202 at one end close to the flip door 11, and the second ball head 1202 can slide in the slide groove 1022. One end of the linkage rod 15 is hinged to the flip door 11, and the other end slides in the slide groove 1022. When the flip door 11 rotates, it drives the other end of the linkage rod 15 to slide in the slide groove 1022. When the other end of the linkage rod 15 abuts against the second ball head 1202, it pushes the second ball head 1202 to slide in the slide groove 1022, thereby driving the first traction rope 12 to move. For example, in the process of opening or closing the flip door 11, the movement of the first traction rope 12 is accurately controlled by the transmission of the linkage rod 15.

[0043] The advantage is that, through the cooperation of the linkage rod 15 and the second ball head 1202 in the slide groove 1022, the rotation of the flip door 11 can be more accurately converted into the linear movement of the first traction rope 12, thereby improving the accuracy of the operation of the entire charging system. This design ensures the stability of the movement of the first traction rope 12, reduces the abnormal movement of the first traction rope 12 caused by the unstable rotation of the flip door 11 or other external factors, and ensures the reliable connection operation of the charging gun. In addition, the slide groove 1022 and the linkage rod 15 are set on the inner wall of the groove 102 by reasonable use of space, further optimizing the internal structure of the charging pile, making the linkage between the various components more compact and reasonable.

[0044] Furthermore, the side wall of the shell 1 also has a plurality of ventilation holes 103 and a swinging scraper 16. The swinging scraper 16 is relatively swingably arranged on the side wall of the shell 1, and after swinging, it scrapes through the plurality of ventilation holes 103 in sequence.

[0045] In this embodiment, in addition to the groove 102, there are also a plurality of ventilation holes 103 on the side wall of the housing 1. The swinging scraper 16 is mounted on the side wall of the housing 1 in a relatively swinging manner. For example, the swinging scraper 16 can achieve relative swinging through a simple pivot structure. During the operation of the charging pile, the swinging scraper 16 will swing continuously and scrape through a plurality of ventilation holes 103 in turn. When dust and debris accumulate around the ventilation holes 103, the swinging scraper 16 will scrape them off to keep the ventilation holes 103 unobstructed.

[0046] The advantage is that the swing of the swing scraper 16 can automatically remove dust and debris on the ventilation hole 103, ensure the ventilation effect of the ventilation hole 103, facilitate heat dissipation inside the charging pile, and improve the operational stability of the charging pile. This design does not require manual regular cleaning of the ventilation hole 103, reduces maintenance costs and workload, and improves the convenience of using the charging pile. Moreover, good ventilation conditions help reduce aging and damage of components inside the charging pile caused by overheating, and extend the overall service life of the charging pile.

[0047] Furthermore, it also includes a rotating shaft 17, which is rotatably arranged on the side wall of the housing 1, with one end of the rotating shaft 17 located in the first cavity 101, and the swing scraper 16 is swingably arranged on the side wall of the housing 1 through the other end of the rotating shaft 17; The rack 18 has one end connected to the sliding steering block 4, and the rack 18 is meshed with one end of the rotating shaft 17 located in the first cavity 101. After the sliding steering block 4 slides, the rack 18 is driven to slide, so that the rotating shaft 17 rotates.

[0048] In this embodiment, in the charging pile, the rotating shaft 17 is rotatably mounted on the side wall of the shell 1, and one end thereof is located in the first cavity 101. The swinging scraper 16 is swingably set on the side wall of the shell 1 through the other end of the rotating shaft 17. At the same time, there is also a rack 18, one end of which is connected to the sliding steering block 4, and is meshed with one end of the rotating shaft 17 located in the first cavity 101. When the charging gun is in use, when the sliding steering block 4 slides with the pulling of the charging line 3, it will drive the rack 18 to slide. The sliding of the rack 18 will cause the rotating shaft 17 to rotate, thereby driving the swinging scraper 16 to swing. For example, when the user plugs in and unplugs the charging gun, this linkage mechanism will be activated to clean the ventilation hole 103.

[0049] The advantage is that this design links the use process of the charging gun with the cleaning function of the ventilation hole 103, making full use of the action of the charging gun when plugging and unplugging, and realizing the swing of the swing scraper 16 without an additional power source, thereby improving the energy efficiency and overall functionality of the charging pile. Through this ingenious mechanical structure design, additional drive devices are reduced, making the internal structure of the charging pile more compact, reducing costs and failure rates. Moreover, it provides users with an intelligent use experience, automatically completing the maintenance function of the charging pile during normal charging operations, and improving user satisfaction.

[0050] Furthermore, it also includes a third elastic member 19, which is arranged in the second slide 1021, and two ends of the third elastic member 19 are respectively in contact with the limiting claw 1201 and the second slide 1021, so as to provide a force for the limiting claw 1201 to slide toward the first cavity 101.

[0051] In this embodiment, a third elastic member 19 is provided in the second slideway 1021 of the charging pile, and the two ends of the third elastic member 19 are respectively in contact with the limiting claw 1201 and the second slideway 1021. When the limiting claw 1201 moves in the second slideway 1021 under the pulling of the first traction rope 12 or the action of other external forces, the third elastic member 19 will undergo elastic deformation. For example, when the flip door 11 opens or closes to drive the limiting claw 1201 to move, the third elastic member 19 is compressed or stretched. When the external force disappears, the third elastic member 19 will use its own elastic restoring force to provide the limiting claw 1201 with a force to slide toward the first cavity 101, so that the limiting claw 1201 returns to the initial position or maintains a stable state.

[0052] The advantage is that the third elastic member 19 can ensure that the limiting claw 1201 can accurately return to the predetermined position after the operation is completed, ensuring the normal operation of the first traction rope 12 and the linkage stability of the entire charging system. It can reduce the possibility of abnormal position of the limiting claw 1201 due to external factors (such as vibration, etc.), and improve the reliability of the charging system during long-term use. In addition, it helps to absorb and buffer the impact force that the limiting claw 1201 may receive during the movement, protect the second slide 1021 and the limiting claw 1201 itself, and extend the service life of related components.

[0053] In actual application scenarios, when the vehicle is connected to the charging gun and starts charging, the DC relay starts. For the six charging modules using a ring connection, they form a stable power supply circuit to ensure stable transmission of power. For example, during the centralized charging period in a large parking lot, multiple vehicles are charged at the same time. This ring connection can effectively balance the load and avoid local overheating or overload problems. The other six independently connectable charging modules automatically allocate power according to the access status of each charging gun. Assuming that one of the charging guns is connected to a vehicle with extremely low power, the system will automatically allocate one or more of the six modules to provide the appropriate charging power for the charging gun. During the entire charging process, the automatic retrieval function monitors the charging status at all times. If a charging module is abnormal, the automatic debugging function will quickly adjust the power output of other modules to maintain the overall charging stability. The automatic detection function will perform real-time detection of the charging gun, charging module and connection line to ensure safety. Moreover, during centralized charging, facing the charging needs of different vehicles, the system can reasonably allocate grouped contactors to maximize economic benefits, such as reducing unnecessary power waste and improving the overall utilization of charging equipment.
