Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a charging pile for new energy electric vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles have almost zero emissions during operation and can significantly reduce greenhouse gas and pollutant emissions.

[0003] New energy electric vehicle charging piles are special devices that provide electric power replenishment for electric vehicles. The improvement of new energy vehicle charging facilities directly eliminates the "range anxiety" of new energy vehicle users. At present, the charging guns of new energy vehicles are mainly stored in the side-mounted manner. When charging, the owner needs to drag the charging gun to the front of the vehicle, and the charging cable falls directly on the ground and is dragged and crushed, which also poses a risk of tripping pedestrians.

[0004] In view of this, the present invention provides a charging pile for new energy electric vehicles to solve the technical problems existing in the prior art. Summary of the Invention

[0005] Based on the technical problems existing in the background technology, the present invention proposes a charging pile for new energy electric vehicles.

[0006] This invention proposes a charging pile for new energy electric vehicles, comprising a base, a lower housing and a mounting frame fixedly installed on the top of the base, the mounting frame being disposed inside the lower housing, and a rotating mechanism extending to the outside of the lower housing being fixedly installed above the mounting frame, an upper housing being fixedly installed on the top of the rotating mechanism, a charging pile controller being fixedly installed on the side of the lower housing, an inwardly recessed mounting groove being provided on the front side of the lower housing, and a charging gun bracket being installed above the mounting groove, the mounting frame serving as the main support structure, and a charging output mechanism being fixedly installed inside the mounting frame, an output cable being fixedly installed at the output end of the charging output mechanism, and a charging gun being installed at the front end of the output cable, a telescopic wire mechanism being fixedly installed at one end of the upper housing, and a heat dissipation mechanism being fixedly installed on the rear side of the lower housing.

[0007] Preferably, in this invention, the rotating mechanism includes a support tube fixedly mounted on a mounting frame, with the top of the support tube rotatably connected to the upper housing. A transmission tube is rotatably mounted inside the support tube, with the top of the transmission tube fixedly connected to the upper housing. A reset motor that drives the transmission tube to rotate is fixedly mounted inside the mounting frame. A wire hole is provided on the top side of the transmission tube, and a protective sleeve is fitted on the outside of the support tube.

[0008] Preferably, in this invention, the heat dissipation mechanism is arranged in an L-shaped structure, with vertically distributed air inlet slots below the heat dissipation mechanism and a filter assembly installed inside the air inlet slots, and horizontally distributed air outlet slots above the heat dissipation mechanism, with an exhaust fan and a grille plate installed inside the air outlet slots in sequence, and multiple sets of downwardly inclined air guide plates arranged between the air inlet slots and the air outlet slots.

[0009] Preferably, in this invention, the filter assembly includes two vertically distributed conical filter bags, and a conical spring frame is fixedly installed on the outer side of the conical filter bags. A magnetic block is provided at the top of the conical spring frame. The filter assembly also includes two vertically distributed electric push rods, and an electromagnet corresponding to the magnetic block is installed at the bottom of the electric push rods.

[0010] Preferably, in this invention, the charging gun holder includes a bracket mounted on the lower housing, and the front end of the bracket is provided with a storage groove that cooperates with the charging gun, and the inside of the storage groove is provided with a plug protection groove.

[0011] Preferably, in this invention, a rotary motor is installed on the bottom of both sides of the bracket, and a movable cover is installed between the output shafts of the two rotary motors. A U-shaped wire groove is provided above the movable cover.

[0012] Preferably, in this invention, the telescopic wire mechanism includes a telescopic slot box installed inside the upper housing. Multiple telescopic tubes that are pluggable to each other are inserted into the front end of the telescopic slot box, and the front end of the telescopic tubes is provided with a J-shaped limiting head. An exhaust fan is installed on the top of the telescopic slot box, and heat dissipation vents are provided on the outside of the telescopic tubes.

[0013] Preferably, in this invention, the upper and lower surfaces of the telescopic tube are provided with racks, the upper and lower positions of the telescopic slot box are each equipped with a torsion spring shaft, and the output shaft end of the torsion spring shaft is equipped with an arc-shaped movable arm. The movable arms distributed vertically are arranged in a C-shape, and a take-up and release roller is rotatably installed between two adjacent movable arms. A motor that drives the take-up and release roller to rotate is installed on the outside of the movable arm.

[0014] Preferably, in this invention, the charging output mechanism includes a charging controller body mounted on a mounting bracket and a winding drum mounted inside the upper housing. The middle part of the output cable is wound around the outside of the winding drum, and a winding motor is provided at one end of the winding drum, while a cooling fan is installed at the other end of the winding drum.

[0015] Preferably, in this invention, the outer side of the output cable is fitted with a spring sheath, and the upper end of the spring sheath is fitted with a limiting ring that is fixedly engaged with the limiting head.

[0016] Compared with the prior art, the present invention provides a charging pile for new energy electric vehicles, which has the following beneficial effects: The output cable is suspended in the air by a telescopic tube. When the charging gun is picked up or put down, the telescopic tube can extend along the length of the output cable, allowing the charging gun to be transferred from the roof of the vehicle and the charging distance to be adjusted at will. This also avoids dragging and abrasion of the output cable on the ground. During charging, the exhaust fan blows air into the telescopic tube, and the cool air flows along the outer wall of the output cable, removing the surface temperature of the output cable and protecting the stability of the power transmission. Under the torque of the torsion spring shaft, the take-up and extend rollers are in close contact with the surface of the telescopic tube. As the take-up and extend rollers move, they drive the telescopic tube to extend forward or retract backward, achieving the effect of automatic delivery or retraction of the charging gun. In particular, after charging is completed, the telescopic tube automatically retracts and resets, preventing the charging gun from affecting the entry and exit of the vehicle and protecting the use of the charging gun.

[0017] Each telescopic tube is equipped with a distance sensor that detects the telescopic distance and direction. When the output cable is pulled outward, the signal of the telescopic tube expanding outward is transmitted to the winding motor, which drives the winding drum to rotate and perform the cable unwinding operation. Conversely, the winding motor drives the winding drum to wind up the cable, keeping the extension length of the output cable synchronized with the length of the telescopic tube. The cooling fan removes the heat from the wound output cable. The spring sleeve creates radial torque on the output cable at the top of the charging gun. When no external force is applied, the charging gun returns to the plug end facing the post direction through the torque of the spring sleeve. When the telescopic cable mechanism retracts and returns to the initial position, the plug end of the charging gun can face the charging gun bracket, and the charging gun can be pressed into the charging gun bracket for protection through the movable cover. At the same time, the spring sleeve enhances the bending resistance of the cable above the charging gun. Attached Figure Description

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] Reference Figures 1-9A new energy electric vehicle charging pile includes a base 1. A lower housing 2 and a mounting frame 12 are fixedly installed on the top of the base 1. The mounting frame 12 is located inside the lower housing 2, and a rotating mechanism 3 extending to the outside of the lower housing 2 is fixedly installed above the mounting frame 12. An upper housing 4 is fixedly installed on the top of the rotating mechanism 3. Both the lower housing 2 and the upper housing 4 are made of outdoor weather-resistant sheet metal. A charging pile controller 5 is fixedly installed on the side of the lower housing 2. The surface of the charging pile controller 5 is provided with a human-machine interactive touch screen and a card swiping recognition area. A recessed mounting groove 7 is provided on the front side of the lower housing 2, and a charging gun bracket 8 is installed above the mounting groove 7. The mounting frame 12 serves as the main support structure, and a charging output mechanism 10 is fixedly installed inside the mounting frame 12. A charging output mechanism 10 is provided at the bottom of the base 1. The charging output mechanism 10 has a strong and weak current separation input channel connected to the input terminal. The input port is equipped with a waterproof and dustproof sealing component. The output end of the charging output mechanism 10 is fixedly installed with an output cable 103. The front end of the output cable 103 is equipped with a charging gun 11. One end of the upper housing 4 is fixedly installed with a telescopic wire mechanism 9. The output cable 103 extends through the telescopic wire mechanism 9 to the outside of the upper housing 4. The rear side of the lower housing 2 is fixedly installed with a heat dissipation mechanism 6. The heat dissipation mechanism 6 corresponds to the inside of the mounting bracket 12. The heat dissipation mechanism 6 is provided with an L-shaped air duct. It draws in cold air from below and blows it onto the charging output mechanism 10, and then pulls it out horizontally from the top to avoid hot air backflow. The heat dissipation mechanism 6 also includes a temperature sensor installed inside the mounting bracket 12. The temperature sensor monitors the internal temperature of the charging pile in real time and controls the operating power of the heat dissipation mechanism 6.

[0022] Reference Figure 3 As a further embodiment of the present invention, the rotating mechanism 3 includes a support tube 31 fixedly mounted on the mounting frame 12, and the top of the support tube 31 is rotatably connected to the upper housing 4. A transmission tube 32 is rotatably mounted inside the support tube 31, and the top of the transmission tube 32 is fixedly connected to the upper housing 4. A reset motor 35 that drives the transmission tube 32 to rotate is fixedly mounted inside the mounting frame 12. A wire hole 33 is provided on the top side of the transmission tube 32, and the output cable 103 passes through the transmission tube 32 and enters the upper housing 4. A protective sleeve 34 is provided on the outside of the support tube 31. The lower housing 2, the mounting frame 12 and the upper housing 4 are connected by the rotating mechanism 3. When the charging gun 11 is picked up, the upper housing 4 swings with the movement of the charging gun 11. After charging is completed, the reset motor 35 drives the transmission tube 32 to rotate and reset, keeping the charging gun 11 aligned with the charging gun bracket 8, which facilitates the recycling operation of the charging gun 11. Reference Figure 4As a further embodiment of the present invention, the heat dissipation mechanism 6 is arranged in an L-shaped structure. A vertically distributed air inlet slot 61 is provided below the heat dissipation mechanism 6, and a filter component is installed inside the air inlet slot 61. A horizontally distributed air outlet slot 62 is provided above the heat dissipation mechanism 6, and an exhaust fan 64 and a grid plate 65 are installed in sequence inside the air outlet slot 62. Multiple sets of downwardly inclined air guide plates 63 are provided between the air inlet slot 61 and the air outlet slot 62. The air guide plates 63 are located on the side of the heat-generating part of the charging output mechanism 10, which disperses the cold air drawn in from below to the area around the heat-generating part of the charging output mechanism 10 and draws it out horizontally from above to prevent hot air backflow. The exhaust fan 64 is a brushless variable frequency axial flow fan. The fan speed is dynamically adjusted according to the internal temperature of the mounting bracket 12 and the load rate of the charging output mechanism 10 to achieve both efficient heat dissipation and low noise operation, thereby enhancing the protection effect. Reference Figure 4 and Figure 5 As a further embodiment of the present invention, the filter assembly includes two vertically distributed conical filter bags 66, and a conical spring frame 67 is fixedly installed on the outer side of the conical filter bags 66. A magnetic block 68 is provided on the top of the conical spring frame 67. The filter assembly also includes two vertically distributed electric push rods 69, and an electromagnet 610 corresponding to the magnetic block 68 is installed at the bottom of the electric push rod 69. The conical filter bags 66 intercept dust in the air. The electric push rods 69 and the electromagnet 610 start and stop at regular intervals. The electric push rods 69 drive the electromagnet 610 to move up and down. Then, through the change in magnetic force generated by the electromagnet 610, the magnetic block 68 is attracted or repelled. This generates an upward traction force or a downward pressure on the conical spring frame 67, causing the conical spring frame 67 and the conical filter bags 66 to stretch and vibrate, quickly cleaning the dust inside the conical filter bags 66, avoiding affecting the intake of cold air, and improving the protection effect of the charging pile. Reference Figure 6 As a further embodiment of the present invention, the charging gun holder 8 includes a bracket 81 mounted on the lower housing 2, and a storage groove 82 that cooperates with the charging gun 11 is provided at the front end of the bracket 81. A plug protection groove 83 is provided inside the storage groove 82. When the charging is finished, after the telescopic wire mechanism 9 rotates and resets, the telescopic wire mechanism 9 drags the output cable 103 and the charging gun 11 to the side of the charging gun holder 8, so that the charging gun 11 can be inserted into the storage groove 82 to complete the recycling operation of the charging gun 11. Rotary motors 84 are installed on both sides of the bottom of the bracket 81, and a movable cover 85 is installed between the output shafts of the two rotary motors 84. A U-shaped wire groove 86 is provided above the movable cover 85. The movable cover 85 can rotate 180-270° under the action of the rotary motors 84. After the charging gun 11 is stored, the movable cover 85 rotates outward from the mounting groove 7 to seal the opening of the bracket 81, thereby storing and protecting the charging gun 11 from rain and other influences. Reference Figure 7 and Figure 8 As a further embodiment of the present invention, the telescopic cable mechanism 9 includes a telescopic slot box 91 installed inside the upper housing 4. Multiple telescopic tubes 92 that are pluggable to each other are inserted into the front end of the telescopic slot box 91. The front end of the telescopic tubes 92 is provided with a J-shaped limiting head 93. An exhaust fan 94 is installed on the top of the telescopic slot box 91. Heat dissipation vents are provided on the outside of the telescopic tubes 92. The output cable 103 is inserted from one end of the telescopic slot box 91 and extends from one end of the limiting head 93. The output cable 103 is then suspended in the air by the telescopic tubes 92. When the charging gun 11 is picked up or put down, the telescopic tubes 92 can extend along the length of the output cable 103 to transfer the charging gun 11 from the roof of the vehicle, change the charging distance at will, and avoid dragging and abrading the output cable 103 on the ground. During the charging operation, the exhaust fan 94 blows air into the telescopic tubes 92. The cold air flows along the outer wall of the output cable 103, taking away the surface temperature of the output cable 103 and protecting the stability of the power transmission of the output cable 103. The telescopic tube 92 is provided with racks 95 on both the upper and lower surfaces. The telescopic slot box 91 is equipped with torsion spring shafts 96 at both the upper and lower positions. The output shaft end of the torsion spring shaft 96 is equipped with an arc-shaped movable arm 97. The movable arms 97 distributed vertically are arranged in a C-shape. A take-up and release roller 98 is rotatably installed between two adjacent movable arms 97. A motor 99 is installed on the outside of the movable arm 97 to drive the take-up and release roller 98 to rotate. The movable arms 97 are arranged in a C-shape at the upper and lower positions of the telescopic tube 92. Under the torque of the torsion spring shaft 96, the take-up and release roller 98 is in close contact with the surface of the telescopic tube 92. As the take-up and release roller 98 moves, it drives the telescopic tube 92 to extend forward or retract backward, achieving the effect of automatic delivery or retraction of the charging gun 11. Especially after the charging is completed, the telescopic tube 92 automatically retracts and resets, preventing the charging gun 11 from affecting the vehicle's entry and exit and protecting the use of the charging gun 11. Reference Figure 6As a further embodiment of the present invention, the charging output mechanism 10 includes a charging controller body 101 mounted on the mounting bracket 12 and a winding drum 102 mounted inside the upper housing 4. The middle part of the output cable 103 is wound around the outside of the winding drum 102, and a winding motor 104 is provided at one end of the winding drum 102. A cooling fan 105 is installed at the other end of the winding drum 102. A temperature sensor for monitoring the temperature of the output cable 103 is installed on the inner wall of the winding drum 102. A distance sensor for sensing the telescopic distance and telescopic direction is installed on each section of the telescopic tube 92. When the output cable 103 is pulled outward, the signal of the telescopic tube 92 expanding outward is transmitted to the winding motor 104. The winding motor 104 drives the winding drum 102 to rotate and perform the unwinding operation. Conversely, the winding motor 104 drives the winding drum 102 to wind up the cable, keeping the extension length of the output cable 103 synchronously changing with the length of the telescopic tube 92, and the cooling fan 105 removes the temperature of the wound output cable 103. A spring sheath 107 is fitted on the outer side of the output cable 103, and a limiting ring 106 that is fixedly engaged with the limiting head 93 is installed on the upper end of the spring sheath 107. The setting of the spring sheath 107 causes the output cable 103 part at the upper end of the charging gun 11 to generate radial torque. When there is no external force, the charging gun 11 is reset to the direction of the plug end over the pile body by the torque of the spring sheath 107. When the telescopic wire mechanism 9 retracts and resets to the initial position, the plug end of the charging gun 11 can face the charging gun bracket 8, and the charging gun 11 can be pressed into the charging gun bracket 8 for protection by the movable cover 85. At the same time, the spring sheath 107 enhances the anti-bending effect of the cable above the charging gun 11.

[0023] In use, the housing 2, mounting bracket 12, and upper housing 4 are connected by a rotating mechanism 3. When the charging gun 11 is picked up, the upper housing 4 swings along with the movement of the charging gun 11. The telescopic tube 92 suspends the output cable 103 in the air. When picking up or putting down the charging gun 11, the telescopic tube 92 can extend along with the length of the output cable 103, transferring the charging gun 11 from the roof of the vehicle, freely changing the charging distance, and avoiding dragging and abrasion of the output cable 103 on the ground. During charging, the exhaust fan 94 blows air into the telescopic tube 92, and the cold air flows along the outer wall of the output cable 103, carrying away the surface temperature of the output cable 103. Each section of the telescopic tube 92 is equipped with a distance sensor that senses the telescopic distance and telescopic direction. When the output cable 103 is pulled outward, the telescopic tube 92 extends outward. The extended signal is transmitted to the take-up motor 104, which drives the take-up drum 102 to rotate for unwinding. Conversely, the take-up motor 104 drives the take-up drum 102 to wind up the cable, keeping the extension length of the output cable 103 synchronized with the length of the telescopic tube 92. After charging is completed, the telescopic tube 92 automatically retracts and resets. Through the setting of the spring sleeve 107, the output cable 103 at the upper end of the charging gun 11 generates radial torque. When there is no external force, the charging gun 11 resets to the direction of the plug end over the post through the torque of the spring sleeve 107. When the telescopic cable mechanism 9 retracts and resets to the initial position, the plug end of the charging gun 11 can face the charging gun bracket 8, and the charging gun 11 can be pressed into the charging gun bracket 8 for protection through the movable cover 85.

[0024] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
