Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging pile technology, specifically to an electric vehicle charging pile with a sunken power supply structure. Background Technology

[0002] With the explosive growth of the global new energy vehicle industry, the construction scale of charging pile infrastructure has expanded exponentially. According to statistics from the International Energy Agency (IEA), the number of public charging piles worldwide exceeded 5 million in 2023, with China accounting for more than 60% of the market. However, traditional charging pile power systems have exposed a series of problems that urgently need to be solved in practical applications: First, ground-mounted power equipment occupies a large area, and in urban commercial areas and residential areas where land is scarce, the installation space for equipment is severely limited; Second, the power system generates a lot of heat when it is working, and fluctuations in ambient temperature can easily lead to a decrease in equipment efficiency or even failure, requiring additional complex heat dissipation devices; Third, traditional power systems adopt a fixed capacity power supply mode, which cannot dynamically adapt to changes in charging load, resulting in the dual problems of "overloading" or operating under excessive load, causing energy waste and shortening equipment life. According to industry data, the average energy efficiency loss of traditional charging pile power systems is as high as 15%-20%, which is particularly obvious during off-peak electricity periods.

[0003] To address the aforementioned industry pain points, this invention proposes an innovative integrated sunken intelligent power supply system for charging piles. Through disruptive structural design and intelligent control technology, it achieves a comprehensive improvement in space utilization, energy efficiency, and operational stability, providing a revolutionary solution for the construction of new energy charging infrastructure. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an electric vehicle charging pile with a sunken power supply structure, comprising a main housing, a heat sink fixedly connected to the side of the main housing, a protective cover fixedly connected to the side of the main housing below the heat sink, a charging gun fixedly connected to the side of the main housing below the protective cover, a movable component fixedly connected to the top of the inner wall of the main housing, a transformer penetrating and fixedly connected to the bottom of the inner wall of the main housing, and a fixing device fixedly connected to the bottom of the main housing;

[0005] The movable component includes a protective frame. A power supply device is fixedly connected to the top of the inner wall of the protective frame. A slider is fixedly connected to the top of the protective frame. A limit rail is fitted and slidably connected to the side of the slider. A connecting rod is rotatably connected to one side of the top of the inner wall of the protective frame via a rotating shaft. A rotating seat is rotatably connected to the end of the connecting rod away from the protective frame. The side of the rotating seat is fixedly connected to the movable part of the main housing. The top of the limit rail is fixedly connected to the top of the inner wall of the main housing. When the housing is opened, the door panel moves the rotating seat, which in turn moves the connecting rod, which in turn moves the protective frame. The protective frame slides along the limit rail under the combined action of the slider and the limit rail, thereby moving the protective frame out. This facilitates overall movement during maintenance, thereby moving the power supply device. Compared to the traditional fixing method of fixing it inside the housing, this increases the convenience of maintenance.

[0006] Preferably, the fixing device includes a fixing housing, a heat dissipation component is fixedly connected to the side of the fixing housing, a fixing component is fixedly connected to the bottom of the fixing housing, a driving component is fixedly connected to the bottom of the inner wall of the fixing housing, a support component is fixedly connected to the top of the driving component, the top of the fixing housing is fixedly connected to the bottom of the main housing, and the side of the heat dissipation component communicates with the side of the driving component.

[0007] Preferably, the heat dissipation assembly includes a heat dissipation frame, a limiting plate fixedly connected to the side of the heat dissipation frame, a heat dissipation pipe fixedly connected to the inner wall of the heat dissipation frame, a guide groove formed on the side of the heat dissipation frame, and the side of the heat dissipation frame fixedly connected to the side of the fixed housing. The heat dissipation pipe passes through the side of the fixed housing and is fixedly connected to the fixed housing. The transformer is placed between the fixed housing and the drive assembly, and cooling oil is directly added for heat conduction, thereby dissipating the heat of the transformer into the oil. The double-layer design of the fixed housing and the drive assembly increases the protection of the transformer. During the long-term operation of the transformer, the oil gradually cools and dissipates heat over time. The heat dissipation medium is designed to prevent complete replacement by separating the outer shell and drive components. The heat dissipation medium is transferred to the interior of the heat dissipation frame through the heat dissipation pipes, thereby transferring heat to the interior of the soil layer. The openings on the side of the heat dissipation frame increase the contact area with the soil layer. At the same time, the soil layer passes through the side of the heat dissipation frame, thereby increasing the stability of the heat dissipation frame. The guide groove design reduces the resistance when the entire heat dissipation frame descends during installation, making it easier to penetrate deeper into the soil layer. The setting of the limit plate limits the depth, thereby keeping multiple installation positions horizontal and making it easy for components to be kept in a horizontal position.

[0008] Preferably, the fixing component includes a fixing seat, a rotating base rotatably connected to the bottom of the fixing seat, a straight blade fixedly connected to the bottom of the rotating base, a helical blade fixedly connected to the bottom of the straight blade, and the top of the fixing seat fixedly connected to the bottom of the fixing housing.

[0009] Preferably, the drive assembly includes a drive housing, an output pipe connected to the top side of the drive housing, an input pipe connected to the bottom side of the drive housing, a drive motor fixedly connected to the top of the drive housing, a fan blade assembly sleeved and fixedly connected to the drive shaft of the drive motor, the bottom of the drive housing fixedly connected to the bottom of the inner wall of the fixed housing, the side of the output pipe connected to the input end of the heat sink, and the output end of the heat sink connected to the side of the input pipe.

[0010] Preferably, the fan blade assembly includes a fixed post, an upper blade rotatably connected to the side of the fixed post, an upper gear ring fixedly connected to the bottom of the upper blade, a reversing gear meshing with the bottom of the upper gear ring, a lower gear ring meshing with the bottom of the reversing gear, and a lower fan blade fixedly connected to the bottom of the lower gear ring. The bottom of the fixed post is fixedly connected to the bottom of the inner wall of the drive housing, and the drive shaft of the drive motor is fixedly connected to the top of the fixed post. The drive shaft of the drive motor drives the upper blade to rotate, the rotation of the upper blade drives the upper gear ring to rotate, the rotation of the upper gear ring drives the reversing gear to rotate, the rotation of the reversing gear drives the lower gear ring to rotate, and the rotation of the lower gear ring drives the lower fan blade to rotate. Thus, the rotation of the upper and lower fan blades drives the heat dissipation medium to move vertically, thereby circulating the heat dissipation medium. The combined action of the upper and lower blades counteracts the vibration of the upper and lower blades, thus preventing vibration from affecting the transformer's operation during heat dissipation and preventing any impact on the transformer's long-term operation. During transformer placement, the transformer's weight presses on the top of the support plate. As the support plate descends, the bottom of the transformer contacts the top of the fastening plate, causing the fastening plate to rotate along the fixed axis. This causes the fastening plate to fasten against the side of the transformer, ensuring the transformer's stability. The rotation angle of the fastening plate is limited by the limiting shaft, preventing excessive rotation under the force of the torsion spring, thereby increasing the transformer's stability and fixing the transformer above the drive housing. This facilitates the passage of the heat dissipation medium through the bottom of the transformer, promoting heat movement and dissipation.

[0011] Preferably, the support assembly includes a telescopic rod, the movable end of which is fixedly connected to a support plate, the top of which is rotatably connected to a fixed shaft, a torsion spring sleeved and fixedly connected to the side of the fixed shaft, a fastening plate sleeved and rotatably connected to the side of the torsion spring, a limit shaft fixedly connected to the bottom of the fastening plate, one end of the torsion spring fixedly connected to the fastening plate, the end of the torsion spring away from the fastening plate fixedly connected to the support plate, and the fixed end of the telescopic rod fixedly connected to the top of the drive housing.

[0012] This invention provides an electric vehicle charging pile with a sunken power supply structure. It has the following beneficial effects:

[0013] 1. This electric vehicle charging pile with a sunken power supply structure is equipped with a rotating seat. When the housing is opened, the door panel moves the rotating seat, which in turn moves the connecting rod. The connecting rod then moves the protective frame. The protective frame slides along the limiting rail under the cooperation of the slider and the limiting rail, thereby moving the protective frame out. This facilitates overall movement during maintenance, thereby moving the power supply device. Compared with the traditional fixing method that is fixed inside the housing, this method increases the convenience of maintenance.

[0014] 2. This electric vehicle charging pile with a sunken power supply structure is equipped with a fixed outer shell. The transformer is placed between the fixed outer shell and the drive assembly, and cooling oil is directly added for heat conduction, thereby dissipating the transformer's heat into the oil. The double-layer design of the fixed outer shell and drive assembly increases the protection of the transformer. During long-term operation of the transformer, the oil will deteriorate over time. The isolation design between the fixed outer shell and the drive assembly avoids the need to replace the entire cooling medium. The cooling medium is carried through the cooling pipes into the interior of the cooling frame, thereby transferring heat to the interior of the soil layer. The openings on the side of the cooling frame increase the contact area with the soil layer. At the same time, the soil layer passes through the side of the cooling frame, thereby increasing the stability of the cooling frame. The design of the guide groove reduces the resistance when the entire cooling frame descends during installation, making it easier to penetrate deeper into the soil layer. The setting of the limit plate limits the depth, thereby keeping multiple installation positions horizontal and ensuring that the components are kept in a horizontal position.

[0015] 3. This electric vehicle charging pile with a sunken power supply structure is equipped with a fixed base. When the fixed outer shell descends, the fixed outer shell drives the fixed base to descend, which in turn drives the rotating base to descend. The rotating base descends, which in turn drives the straight blades to descend, which in turn drives the spiral blades to descend. During the descent, the spiral blades move along the soil layer, thereby driving the spiral blades to rotate. The rotation of the spiral blades drives the straight blades to rotate, which in turn drives the rotating base to rotate along the fixed base, thereby increasing the fixation effect on the soil layer. The spiral design of the spiral blades increases the contact area with the soil layer, thereby increasing friction and improving the stability of the equipment. The drive motor is started, which drives the heat dissipation medium to move, and also drives the heat dissipation medium to move along the input pipe and output along the output pipe, thereby driving the heat dissipation medium to move along the heat dissipation pipe, moving the heat. The fan blade assembly drives the heat dissipation medium to move inside the drive shell, thereby increasing the heat dissipation efficiency through the combination of active and passive heat dissipation, thus controlling the transformer to be in the optimal temperature range.

[0016] 4. This electric vehicle charging pile with a sunken power supply structure is equipped with a drive motor. The drive shaft of the drive motor drives the upper blades to rotate, which in turn drives the upper gear ring to rotate. The upper gear ring then drives the reversing gear to rotate, which in turn drives the lower gear ring to rotate. The lower gear ring then drives the lower fan blades to rotate. This rotation of the upper and lower fan blades causes the heat dissipation medium to move vertically, thus circulating the medium. The combined action of the upper and lower fan blades counteracts their vibration, preventing vibration during heat dissipation from affecting the transformer's operation and thus preventing the transformer from failing over long periods of time. During operation, the transformer's weight presses down on the top of the support plate as it is placed. As the support plate descends, the bottom of the transformer contacts the top of the fastening plate, causing the fastening plate to rotate along the fixed axis. This causes the fastening plate to fasten against the side of the transformer, ensuring its stability. The rotation angle of the fastening plate is limited by the limiting shaft, preventing excessive rotation under the force of the torsion spring, thus increasing the transformer's stability and fixing it above the drive housing. This allows the heat dissipation medium to pass through the bottom of the transformer, facilitating heat movement and dissipation. Attached Figure Description

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figures 1-2The present invention provides a technical solution: an electric vehicle charging pile with a sunken power supply structure, including a main body 1, a heat sink 2 fixedly connected to the side of the main body 1, a protective cover 3 fixedly connected to the side of the main body 1 below the heat sink 2, a charging gun 4 fixedly connected to the side of the main body 1 below the protective cover 3, a movable component 5 fixedly connected to the top of the inner wall of the main body 1, a transformer 6 penetrating and fixedly connected to the bottom of the inner wall of the main body 1, and a fixing device 7 fixedly connected to the bottom of the main body 1.

[0028] The main housing 1 provides overall support for the equipment, the heat sink 2 dissipates heat from the internal space of the main housing 1, the protective cover 3 protects the charging gun 4 from rain, the moving component 5 moves the internal components, making it easy to remove the internal components during maintenance, thus facilitating maintenance. The transformer 6 is located between the underground and the interior of the main housing 1, and through contact with the fixing device 7, it releases heat into the ground, thus facilitating heat dissipation. The fixing device 7 fixes the main housing 1, thus facilitating stable installation of the housing. The components at the bottom of the fixing device 7 fix the main housing 1 to the ground, thus increasing the stability of the housing.

[0029] The movable component 5 includes a protective frame 501. A power supply device 502 is fixedly connected to the top of the inner wall of the protective frame 501. A slider 503 is fixedly connected to the top of the protective frame 501. A limit rail 504 is sleeved and slidably connected to the side of the slider 503. A connecting rod 505 is rotatably connected to one side of the top of the inner wall of the protective frame 501 via a rotating shaft. A rotating seat 506 is rotatably connected to the end of the connecting rod 505 away from the protective frame 501. The side of the rotating seat 506 is fixedly connected to the movable part of the main housing 1. The top of the limit rail 504 is fixedly connected to the top of the inner wall of the main housing 1.

[0030] When the enclosure is opened, the door panel moves the rotating seat 506, which in turn moves the connecting rod 505. The connecting rod 505 then moves the protective frame 501. Under the combined action of the slider 503 and the limiting slide rail 504, the protective frame 501 slides along the limiting slide rail 504, thereby allowing it to be moved out. This facilitates overall movement during maintenance, which in turn moves the power supply device 502. Compared to the traditional method of fixing the device inside the enclosure, this increases the convenience of maintenance.

[0031] Please see Figures 1-4The present invention provides a technical solution: the fixing device 7 includes a fixing shell 701, a heat dissipation component 702 is fixedly connected to the side of the fixing shell 701, a fixing component 703 is fixedly connected to the bottom of the fixing shell 701, a driving component 704 is fixedly connected to the bottom of the inner wall of the fixing shell 701, a support component 705 is fixedly connected to the top of the driving component 704, the top of the fixing shell 701 is fixedly connected to the bottom of the main housing 1, and the side of the heat dissipation component 702 communicates with the side of the driving component 704.

[0032] The heat dissipation assembly 702 includes a heat dissipation frame 7021, a limiting plate 7022 fixedly connected to the side of the heat dissipation frame 7021, a heat dissipation pipe 7023 fixedly connected to the inner wall of the heat dissipation frame 7021, a guide groove 7024 opened on the side of the heat dissipation frame 7021, the side of the heat dissipation frame 7021 fixedly connected to the side of the fixed housing 701, and the heat dissipation pipe 7023 passing through the side of the fixed housing 701 and fixedly connected to the fixed housing 701.

[0033] Transformer 6 is placed between the fixed housing 701 and the drive assembly 704, and heat dissipation oil is directly added for heat conduction, thereby dissipating the heat of transformer 6 into the oil. The double-layer design of the fixed housing 701 and the drive assembly 704 increases the protection of transformer 6. During the long-term operation of transformer 6, the oil will deteriorate over time. The isolation design between the fixed housing 701 and the drive assembly 704 avoids the need to replace the entire heat dissipation medium. The heat dissipation medium passes through the heat dissipation pipe 7023 and is circulated into the interior of the heat dissipation frame 7021, thereby transferring heat to the interior of the soil layer. The openings on the side of the heat dissipation frame 7021 increase the contact area with the soil layer. At the same time, the soil layer passes through the side of the heat dissipation frame 7021, thereby increasing the stability of the heat dissipation frame 7021. The design of the guide groove 7024 reduces the resistance when the entire heat dissipation frame 7021 descends during installation, making it easier to penetrate deeper into the soil layer. The setting of the limiting plate 7022 limits the depth, thereby keeping multiple installation positions horizontal and making it easier for components to be kept in a horizontal position.

[0034] Please see Figures 1-6 The present invention provides a technical solution: the fixing component 703 includes a fixing seat 7031, a rotating base 7032 is rotatably connected to the bottom of the fixing seat 7031, a straight blade 7033 is fixedly connected to the bottom of the rotating base 7032, a spiral blade 7034 is fixedly connected to the bottom of the straight blade 7033, and the top of the fixing seat 7031 is fixedly connected to the bottom of the fixing housing 701.

[0035] The drive assembly 704 includes a drive housing 7041. An output pipe 7042 is connected to the top side of the drive housing 7041, and an input pipe 7043 is connected to the bottom side of the drive housing 7041. A drive motor 7044 is fixedly connected to the top of the drive housing 7041. A fan blade assembly 7045 is sleeved and fixedly connected to the drive shaft of the drive motor 7044. The bottom of the drive housing 7041 is fixedly connected to the bottom of the inner wall of the fixed housing 701. The side of the output pipe 7042 is connected to the input end of the heat sink 7023, and the output end of the heat sink 7023 is connected to the side of the input pipe 7043.

[0036] When the fixed outer casing 701 descends, it drives the fixed base 7031 to descend, which in turn drives the rotating base 7032 to descend. The descending of the rotating base 7032 drives the straight blade 7033 to descend, which in turn drives the helical blade 7034 to descend. During this descent, the helical blade 7034 moves along the soil layer, thus rotating. This rotation of the helical blade 7034 drives the straight blade 7033 to rotate, which in turn drives the rotating base 7032 to rotate along the fixed base 7031. This increases the fixation effect on the soil layer, and through the screw... The spiral design of the blade 7034 increases the contact area with the soil layer, thereby increasing friction and improving the stability of the equipment. The drive motor 7044 is started, which drives the heat dissipation medium to move, and also drives the heat dissipation medium to move along the input pipe 7043 and output along the output pipe 7042, thereby driving the heat dissipation medium to move along the heat dissipation pipe 7023, carrying heat away, and through the fan blade assembly 7045, the heat dissipation medium moves inside the drive housing 7041, thereby increasing the heat dissipation efficiency through the combination of active and passive heat dissipation, thereby controlling the transformer 6 to be in the optimal temperature range.

[0037] Please see Figures 1-8 The present invention provides a technical solution: the fan blade assembly 7045 includes a fixing post 70451, an upper blade 70452 is sleeved and rotatably connected to the side of the fixing post 70451, an upper gear ring 70453 is fixedly connected to the bottom of the upper blade 70452, a reversing gear 70454 is meshed at the bottom of the upper gear ring 70453, a lower gear ring 70456 is meshed at the bottom of the reversing gear 70454, a lower fan blade 70457 is fixedly connected to the bottom of the lower gear ring 70456, the bottom of the fixing post 70451 is fixedly connected to the bottom of the inner wall of the drive housing 7041, and the drive shaft of the drive motor 7044 is fixedly connected to the top of the fixing post 70451.

[0038] The support assembly 705 includes a telescopic rod 7051, a support plate 7052 fixedly connected to the movable end of the telescopic rod 7051, a fixed shaft 7053 rotatably connected to the top of the support plate 7052, a torsion spring 7054 sleeved and fixedly connected to the side of the fixed shaft 7053, a fastening plate 7055 sleeved and rotatably connected to the side of the torsion spring 7054, a limit shaft 7056 fixedly connected to the bottom of the fastening plate 7055, one end of the torsion spring 7054 fixedly connected to the fastening plate 7055, and the end of the torsion spring 7054 away from the fastening plate 7055 fixedly connected to the support plate 7052. The fixed end of the telescopic rod 7051 is fixedly connected to the top of the drive housing 7041.

[0039] The drive shaft of the drive motor 7044 drives the upper blade 70452 to rotate. The rotation of the upper blade 70452 drives the upper gear ring 70453 to rotate, which in turn drives the reversing gear 70454 to rotate. The reversing gear 70454 then drives the lower gear ring 70456 to rotate, which in turn drives the lower fan blade 70457 to rotate. The rotation of the upper blade 70452 and the lower fan blade 70457 causes the heat dissipation medium to move vertically, thus circulating the medium. The combined action of the upper blade 70452 and the lower fan blade 70457 counteracts their vibration, preventing vibration during heat dissipation from affecting the operation of the transformer 6 and thus preventing the transformer 6 from operating under conditions of prolonged stress. During operation, when the transformer 6 is placed, its weight presses on the top of the support plate 7052. As the support plate 7052 descends, the bottom of the transformer 6 contacts the top of the fastening plate 7055, causing the fastening plate 7055 to rotate along the fixed shaft 7053. This causes the fastening plate 7055 to fasten the side of the transformer 6, ensuring the stability of the transformer 6. The rotation angle of the fastening plate 7055 is limited by the limiting shaft 7056, preventing the fastening plate 7055 from rotating excessively under the elastic force of the torsion spring 7054, thereby increasing the stability of the transformer 6 and fixing the transformer 6 above the drive housing 7041. This facilitates the passage of the heat dissipation medium through the bottom of the transformer 6, thus facilitating heat movement and dissipation.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
