Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to a new energy vehicle charging pile. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. With the continuous progress of society, the development of new energy vehicles has entered a stage of rapid change, thus the electric vehicle power supply market has become huge, and the demand for the number of electric vehicle charging piles has also increased accordingly. In the prior art, patent CN222040254U discloses a new energy vehicle charging pile, including a box and a housing. A lifting mechanism is fixedly installed on the side wall of the box, and the lifting mechanism includes sliding plates fixedly installed on both sides of the housing. A cover mechanism is fixedly installed on the top of the housing, and the cover mechanism includes an electric telescopic rod. A charging pile mechanism is provided inside the housing, including a charging pile body fixedly installed on the bottom wall of the housing. A winding mechanism is fixedly installed on the front side of the charging pile mechanism, and the winding mechanism includes a winding roller. The above-mentioned new energy vehicle charging piles have some problems in actual use. When the single winding roller winds up the charging cable, there is no cable management structure. The winding and unwinding speed of the charging cable is determined by the motor speed. If the speed is constant, the cable may be wound up at the same position, and the cable is easy to tangle, resulting in discontinuous winding and unwinding operations. Therefore, we propose a new energy vehicle charging pile. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This embodiment provides a technical solution: a new energy vehicle charging pile, including a pile body 1. The pile body 1 has mounting slots 2 on its left and right sides respectively. The front side of the pile body 1 is provided with a controller 8. The input end of the controller 8 is electrically connected to an external power source, and the input end of the pile body 1 is electrically connected to the output end of the controller 8 (the communication module of the pile body 1 communicates with the vehicle's battery management system through the CAN bus or PWM signal in the charging gun; the power module of the pile body 1 is essentially a high-voltage relay, triggered by the control unit command). It also includes a cable winding mechanism 3 and a cable management mechanism 4. The left and right sides of the pile body 1 are respectively fixedly connected with sealing plates 6. When the vehicle charging pile is needed, the new energy vehicle can be parked around the charging pile, and a suitable charging gun 35 model can be selected (the charging gun 35 on the left side is a Type 1 interface, and the connector model is SAE J1772; the charging gun 35 on the right side is a Type 2 interface, and the Type 2 is a LY-EVAC series connector transmission connector). At this time, the charging cable 34 of a specified length can be pulled out according to the distance between the vehicle's charging port and the charging pile. The coiling mechanism 3 includes a rotating drum 31, a conductive ring 32, a spiral wire groove 33, a charging cable 34, and a charging gun 35. The rotating drum 31 is rotatably connected between the upper and lower inner walls of the two mounting grooves 2. The conductive ring 32 is fixedly connected to the upper side of the rotating drum 31. The fixed end of the left conductive ring 32 is fixedly connected to the upper side wall of the left mounting groove 2, and the fixed end of the right conductive ring 32 is fixedly connected to the upper side wall of the right mounting groove 2. (The conductive ring 32 is composed of a hollow rotor, an annular conductive ring, a fixed brush assembly, and an insulating layer. The hollow rotor is the core load-bearing component, with a through hole in the center, which is fixedly connected to the upper side of the outer arc surface of the rotating drum 31.) An annular conductive track is fixed to the inner wall of the hollow rotor, distributed along the circumference, and fixes the brush assembly. It is installed inside the housing and tightly adheres to the track via an elastic mechanism, connecting to the inner wall of the mounting groove 2. An insulating layer separates different tracks and simultaneously supports the relative rotation of the hollow rotor and the housing. When the rotating drum 31 rotates, driving the hollow rotor and the track to rotate, the brushes, fixed to the housing, remain stationary, generating low-friction sliding contact with the rotating track surface, achieving independent coordination of "mechanical rotation" and "electrical transmission." The outer arc surface of the rotating drum 31 is provided with spiral wire grooves 33, and each spiral wire groove 33 contains a charging wire 34 (the outer arc surface of the charging wire 34 is...). The upper side of the charging cable 34 is fixedly connected to the upper end of the rotating drum 31. Specifically, this can be achieved by wrapping wire around the outer surface of the rotating drum 31, pressing the upper end of the charging cable 34 against the upper side of the outer arc surface of the rotating drum 31, and then connecting the upper end of the charging cable 34 to the output end of the conductive ring 32. Alternatively, a groove can be made inside the rotating drum 31, with the charging cable 34 vertically passing through and fixed inside the groove. The upper end of the charging cable 34 is then connected to the output end of the conductive ring 32 (ensuring the charging cable 34 is fixedly attached to the upper side of the rotating drum 31 to prevent it from becoming loose). The ends of the two charging cables 34 are respectively fixedly connected to charging guns 35. The upper input end of the conductive ring 32 is electrically connected to the output end of the pile body 1, and the lower output ends of the two conductive rings 32 are electrically connected to the upper ends of the charging lines 34 corresponding to the vertical positions. The input ends of the two charging guns 35 are electrically connected to the output ends of the charging lines 34 located on the same side. The coiling mechanism 3 also includes slots 36 and sockets 37. The slots 36 are respectively opened on the upper side of the left side and the upper side of the right side of the pile body 1. The two slots 36 are respectively provided with sockets 37 inside (the socket type of the socket 37 is selected according to the socket type of the charging gun 35 to ensure that the charging gun 35 can be temporarily inserted into the socket 37 when it is not in use). Cable management mechanism 4: It is set inside the mounting groove 2. The cable management mechanism 4 includes a sliding groove 41, a slider 42, a screw 43, and a wire cylinder 44. The sliding grooves 41 are respectively opened on the rear side wall of the two mounting grooves 2. The sliders 42 are slidably connected inside the two sliding grooves 41 respectively. The wire cylinders 44 are fixedly connected to the front side of the two sliders 42 respectively. The screw 43 is rotatably connected between the upper and lower inner walls of the left sliding groove 41, and the screw 43 is also rotatably connected between the upper and lower inner walls of the right sliding groove 41. The threaded surfaces of the two screws 43 are respectively threadedly connected to the middle part of the slider 42 located in the same sliding groove 41 (the upper and lower surfaces of the slider 42 can be fitted with corrugated tubes. The upper end of the upper corrugated tube is fixedly connected to the upper side wall of the mounting groove 2, and the lower corrugated tube is fixedly connected to the upper side wall of the mounting groove 2). The lower end of the screw 43 is fixedly connected to the lower side wall of the mounting groove 2. The bellows is sleeved on the outside of the screw 43. At the same time, the bellows seals the external thread surface of the screw 43. As the slider 42 moves up and down, the bellows will adaptively expand and contract to protect the external thread surface of the screw 43 in real time and prevent the external thread surface of the screw 43 from being contaminated. The cable management mechanism 4 also includes a lower transmission mounting groove 45, a first gear 46 and a second gear 47. The lower sides of the two mounting grooves 2 are respectively provided with lower transmission mounting grooves 45. The lower sides of the two rotating drums 31 are respectively fixedly connected with the first gear 46. The lower ends of the two screws 43 are respectively fixedly connected with the second gear 47. The first gear 46 on the left is meshed with the second gear 47 on the left, and the first gear 46 on the right is meshed with the second gear 47 on the right. Gears 47 are meshed together. The first gear 46 and the second gear 47 on the left are located inside the lower transmission mounting groove 45 on the left side, and the first gear 46 and the second gear 47 on the right are located inside the lower transmission mounting groove 45 on the right side (here, the lead of the screw 43 is 1, that is, when the screw 43 rotates one revolution, the slider 42 moves up and down 1mm, and the transmission ratio of the first gear 46 to the second gear 47 is 10:1, that is, when the screw 43 rotates 10 revolutions, it drives the second gear 47 to rotate one revolution, which means that the slider 42 moves up and down 1cm, and the wire tube 44 rotates one revolution, releasing the charging cable 34 on the wire tube 44 one revolution, and the diameter of the wire tube 44 is 16cm, and the released charging cable 34 is 50cm). The upper left and upper right sides of the inside of the pile body 1 are respectively provided with Two motors 5 have their output ends fixedly connected to the upper ends of screws 43 in the vertical positions, respectively. The input ends of the two motors 5 are electrically connected to the output ends of controller 8. Two cable trays 7 are fixedly connected to the lower sides of the two sealing plates 6. The charging cable 34 on the left passes horizontally through the interior of the left cable tray 44 and the left cable tray 7 (the inside of the cable tray 7 has evenly distributed bead grooves, with iron beads rotating inside, allowing the outer arc surface of the iron beads to contact the outer surface of the charging cable 34, reducing friction and ensuring it can freely pass through the cable tray 7). The charging cable 34 on the right passes horizontally through the interior of the right cable tray 44 and the right cable tray 7. Controlling the controller 8 causes the corresponding motor 5 to operate, and the output shaft of the motor 5 rotates.This causes the screw 43 to rotate in both directions, which in turn causes the slider 42 to adjust its height within the groove 41. During this process, the second gear 47 rotates, which in turn causes the first gear 46 to rotate, which in turn causes the rotating drum 31 to rotate. The clockwise rotation of the rotating drum 31 directs the charging cable 34 within the spiral cable groove 33. Simultaneously, the slider 42 moves upward, causing the wire drum 44 to move upward as well. The height at which the charging cable 34 is released corresponds to the real-time height of the wire drum 44. The charging cable 34, originally wound within the spiral cable groove 33, is gradually released. These charging cables 34 are eventually led out of the charging pile along the wire drum 44 (at this point, the charging gun 35 needs to be manually guided and pulled) until the charging gun 35 is connected to the charging port of the new energy vehicle. Furthermore, after the communication module inside the charging pile 1 detects that the charging gun 35 is matched with the new energy vehicle, the motor 5 stops running, thereby stopping the cable laying operation. At this time, the controller 8 can be controlled to charge the new energy vehicle. (After the detection is successful, the charging pile 1 communicates with the vehicle's BMS to confirm the "capability matching" between the two parties. The charging pile 1 control unit instructs the "power module (contactor)" to close, connecting the AC circuit from the power grid to the charging gun 35. The AC power from the power grid is transmitted to the on-board charger inside the vehicle through the charging gun 35 and the vehicle's charging interface. Specifically, after the charging pile 1 is successfully matched with the vehicle, the charging pile 1 directly transmits the AC power from the power grid to the vehicle. The actual energy conversion is completed inside the vehicle. The "on-board charger (OBC)" in the vehicle converts the AC power into DC power, which is then controlled by the BMS to charge the battery.)

[0016] The working principle of the new energy vehicle charging pile provided by this utility model is as follows: When the charging pile is needed, the new energy vehicle can be parked around the charging pile. A suitable charging gun 35 model is selected (the charging gun 35 on the left is a Type 1 interface, and the charging gun 35 on the right is a Type 2 interface). Then, according to the distance between the vehicle's charging port and the charging pile, the charging cable 34 of the specified length can be pulled out. Specifically, the controller 8 is adjusted, and the corresponding motor 5 operates. The output shaft of the motor 5 rotates, thereby driving the screw 43 to rotate in both directions. This, in turn, drives the slider 42 to adjust its height within the groove 41. During this process, the second gear 47 rotates, which in turn drives the first gear 46 to rotate, thereby driving the rotating drum 31 to rotate. The clockwise rotation of the rotating drum 31 directs the charging cable 34 within the spiral cable groove 33. Simultaneously, slider 42 will also move upward, driving wire cylinder 44 to move upward at the same time. The height of the charging cable 34 is corresponding to the height of wire cylinder 44 in real time. The charging cable 34 originally wound in the spiral wire groove 33 is gradually released. These charging cables 34 are finally led out of the charging pile along wire cylinder 44 until the charging gun 35 is connected to the charging port of the new energy vehicle. After the communication module inside the pile body 1 detects that the charging gun 35 is matched with the new energy vehicle, the motor 5 stops running, thereby stopping the cable release operation. At this time, the controller 8 can be controlled to charge the new energy vehicle.

[0017] It is worth noting that the core chip of the controller 8 disclosed in the above embodiments is a microcontroller, specifically the STM32F207ZET. The charging pile 1, conductive ring 32, charging gun 35, and motor 5 can be freely configured according to the actual application scenario. It is recommended that the charging pile 1 be a new energy vehicle charging pile of model DQKC-60-120-240, the conductive ring 32 be a JST60135 standard through-hole conductive slip ring, and the motor 5 be a 130BL servo motor. The controller 8 controls the operation of the charging pile 1 and the motor 5 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
