Description

Technical Field

[0001] This application relates to the technical field of charging piles, and in particular to an outdoor charging pile for electric vehicles. Background Technology

[0002] In recent years, guided by national policies and with the broad participation of enterprises, the electric vehicle industry has developed rapidly, and the demand for corresponding supporting charging facilities is also increasing, especially outdoor charging piles for electric vehicles. Existing outdoor charging piles for electric vehicles are mainly composed of charging modules, monitoring modules, voltage stabilization modules, etc. Among them, the voltage stabilization module is mainly composed of a transformer, which protects the voltage and current inside the charging pile to prevent damage to the car battery caused by fluctuations in current.

[0003] Among existing outdoor charging stations for electric vehicles, a large number of charging stations have been disclosed. Chinese patent CN211519286U discloses a heat dissipation structure for a charging station, including the charging station itself. A heat dissipation device is installed at the bottom of the charging station, and a fan is installed inside the heat dissipation device. One end of a connecting rod is fixedly connected to a heat sink, and the fan has fan blades inside. This invention, by installing a heat dissipation device at the bottom of the charging station, with a cooling fan inside and heat sinks on the outer surface of the fan, significantly improves the heat dissipation efficiency of the charging station and reduces the failure rate caused by high temperatures. A rainproof eave is installed at the top of the charging station, and a rainproof groove is provided on the outer surface of the casing. Rainwater will fall directly to the ground along the rainproof eave, and the rainproof groove effectively protects the display screen and magnetic card sensor.

[0004] However, the aforementioned charging piles use ventilation openings and cooling fans to dissipate heat from their interiors. These fans can only effectively cool one side of the electronic components inside the charging pile, leaving heat from other directions undissipated. Furthermore, the cooling fans are located at the bottom of the charging pile, preventing effective cooling of the upper part of the internal components. This can cause the components to operate in high-temperature environments for extended periods, shortening their lifespan. In particular, if the transformer, which generates the most heat inside the charging pile, cannot be effectively cooled, it could even spontaneously combust.

[0005] Secondly, existing charging stations are generally equipped with transformers to ensure the circuitry of the charging station. When the transformer is hit, it will generate a large number of electrical sparks, which may cause the charging station to catch fire. However, existing charging stations are only protected by the outer shell. If a car accidentally steps on the brake or accelerator while reversing into a parking space to charge, it may cause the car to collide with the charging station, which may be dangerous.

[0013] Preferably, the sealing module includes hidden grooves on the left and right sides of the charging housing and located at the upper end of the square ventilation slot.

[0019] 3. The inductive levitation ball in the lifting mechanism actively lifts the charging shell by sensing the depth of rainwater to prevent the charging pile from being soaked in rainwater during heavy rain.

[0020] 4. By using electric fans in conjunction with cooling fans to dissipate heat over a large area inside the charging pile, the stability of the electronic components inside the charging pile is ensured, thereby greatly improving their service life.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0037] This application discloses an outdoor charging pile for electric vehicles. During the charging process, the charging pile can quickly dissipate heat inside the charging pile, reduce the temperature of the internal components, and improve their service life. Furthermore, this embodiment can protect the charging pile from accidents that may occur when the car is reversing into a parking space, causing the car to collide with the charging pile.

[0038] Example 1: See Figure 1 and Figure 2 As shown, this application discloses an outdoor charging pile for electric vehicles, which includes a charging shell 1 and a support base 2 for placing the lower end of the charging shell 1 on the ground. In actual outdoor charging piles for electric vehicles, the charging pile is placed on the ground by the support base 2, and the ground and the support base 2 support the charging shell 1 to ensure the stability of the charging shell 1 and its internal parts. The charging housing 1 is equipped with a fast heat sink 3 for dissipating heat from the electronic components inside the charging pile. When charging at an actual outdoor charging pile, a transformer is needed to ensure voltage stability, thereby enabling the charging pile to adjust the voltage for different fast and slow charging. The transformer will continuously generate heat during operation. In order to improve its heat dissipation efficiency, ensure its service life, and avoid it from working in a high-temperature environment for a long time, the fast heat sink 3 is used to dissipate heat, so that the inside of the charging housing 1 is always in a relatively constant environment. The outer side of the charging housing 1 is equipped with a lifting mechanism 4 to protect the charging pile. When the car needs to be charged, it will be driven into a professional charging parking space. Therefore, in order to prevent some drivers from reversing too fast and crashing into the charging pile due to anxiety about low battery, the lifting mechanism 4 is used to protect the main body of the charging pile and avoid damage to its internal parts, which could lead to leakage of high voltage and, in severe cases, cause the charging pile to explode and catch fire.

[0039] See Figure 2 As shown, after the internal components and wires of the charging housing 1 are installed, the charging pile can be installed on the ground to charge the electric vehicle. During the charging process, the charging housing 1 will generate a lot of heat. In order to improve the heat dissipation efficiency, this embodiment proposes a fast radiator 3. Specifically, the fast radiator 3 includes a cooling motor 30 fixedly installed on the rear side of the charging housing 1. The output end of the cooling motor 30 passes through the charging housing 1 through the bearing and is connected to the drive gear 31. When the operator drives the electric vehicle into the dedicated parking space and inserts the charging gun of the charging pile into the car for charging, the cooling motor 30 starts and drives the entire drive gear 31 to rotate.

[0040] A plurality of planetary gears 32 are evenly spaced along the circumferential direction on the outer side of the drive gear 31. A gear ring 33 is meshed on the outer side of the plurality of planetary gears 32. The gear ring 33 is fixedly mounted on the inner wall of the charging housing 1. The plurality of planetary gears 32 are interconnected by connecting rods. A transformer fixing module 34 is provided on the front side of the planetary gears 32. During the rotation of the drive gear 31, the four planetary gears 32 meshing with it are driven to rotate synchronously through the mutual cooperation of the drive gear 31 and the gear ring 33. During the rotation of the four planetary gears 32, the transformer fixed by the transformer fixing module 34 rotates 360 degrees in both directions. When the transformer fixing module 34 rotates back and forth, it provides rapid heat dissipation for the transformer that is in operation. At the same time, the reciprocating rotation of the transformer can prevent dust from accumulating on the surface of the transformer and ensure the cleanliness of the transformer.

[0041] See Figure 3 and Figure 4 As shown, the transformer fixing module 34 includes a clamping plate 340 fixedly installed on the front side of the planetary gear 32. The main function of the clamping plate 340 is to support the transformer. Each end of the clamping plate 340 near the drive gear 31 is fixedly installed with a limiting plate 341 that alternates with the heat sink on the transformer. Several heat sinks are evenly spaced on the outer side wall of the transformer. During the installation of the transformer, the operator alternately aligns and contacts the limiting plate 341 on the clamping plate 340 with the heat sink on the transformer. Then, the transformer is placed on the four clamping plates 340 to ensure that the transformer is limited and fixed by the clamping plates 340.

[0042] A fixing groove is provided on the outer wall of the clamping plate 340. A right-angle clamping block 343 for clamping the corners of the transformer is connected in the fixing groove through a fixing spring 342. A wire harness stabilizing component 35 is provided on the clamping plate 340 to fix the wires connected to the transformer. After the transformer is placed between the four clamping plates 340, the transformer needs to be further fixed to prevent the transformer's heat sink from being deformed due to excessive force. Therefore, the operator fixes the four corners of the transformer with the right-angle clamping block 343 while installing the transformer. The fixing spring 342 mainly plays the role of allowing the right-angle clamping block 343 to move within a small range, which can fix the position of the transformer and ensure the convenience of transformer installation.

[0043] See Figure 5 and Figure 6As shown, after the transformer is fixed between the clamping plates 340, it is necessary to connect the terminals on the transformer to other components inside the charging housing 1. Based on this, in this embodiment, the upper end of the clamping plate 340 is provided with a wire harness stabilizing component 35 for centralized fixing and limiting the wire harness. Specifically, the wire harness stabilizing component 35 includes a sliding groove on the outer wall of the gear ring 33. The sliding groove is an I-shaped structure. The wire harness assembly block 350 on the gear ring 33 is limited by the I-shaped sliding groove to prevent the wire harness assembly block 350 from falling off while rotating with the transformer.

[0044] A wire harness assembly block 350 is slidably connected in the sliding groove. The wire harness assembly block 350 is provided with several wire harness through holes 351 for fixing the wire harness, corresponding to the terminals on the transformer. The wire harness assembly block 350 is a hollow structure. A wire harness fixing block 352 is slidably connected in the stabilizing groove and above the wire harness through holes 351. A locking threaded rod 353 is provided on the upper end of the wire harness fixing block 352. The locking threaded rod 353 is installed on the wire harness assembly block 350 by threaded connection. The wire harness assembly block 350 and the clamping plate 340 are connected by a support rod 354.

[0045] Specifically, after the operator connects the wire to the terminal on the transformer, the other end of the wire is passed through the wire harness through hole 351 on the wire harness fixing block 352, and the wire between the transformer terminal and the wire harness through hole 351 is in a loose state. Then the operator rotates the locking thread rod 353, which drives the wire harness fixing block 352 to squeeze and fix the wire located inside the wire harness through hole 351, so as to prevent the transformer terminal from becoming loose and the wire from becoming loose during the process of the transformer rotating to dissipate heat. As the transformer rotates, the wire harness assembly block 350 and the clamping plate 340 are connected by a support rod 354, so the two can rotate synchronously. This ensures that the end of the transformer that is in contact with the wire remains relatively stationary, thereby avoiding poor contact between the transformer and the wire.

[0046] See Figure 5 , Figure 6 and Figure 7 As shown, a support shaft 11 is rotatably connected to the inner side of the charging housing 1 and above the wire harness assembly block 350 via a bracket 10. A winding roller 12 for winding the wire harness is fixedly connected to the support shaft 11. A spiral spring 13 is fixedly connected to the side end of the support shaft 11. One end of the spiral spring 13 is fixed to the bracket 10, and the other end of the spiral spring 13 is connected to the support shaft 11.

[0047] Specifically, after the wire harness is fixed on the wire harness assembly block 350, in the initial state, the wire harness assembly block 350 is located directly above the gear ring 33. The end of the wire harness away from the wire harness assembly block 350 is wound by winding each wire onto a corresponding winding roller 12. This maintains the aesthetics of the wires while ensuring that the wires can freely extend and retract. When the transformer rotates clockwise, the wire harness assembly block 350 pulls the wound wire harness out from the winding roller 12. When the transformer rotates in reverse, the pulled-out wire harness is automatically retracted by the elastic force of the spiral spring 13 until it returns to its initial state.

[0048] See Figure 8 As shown, square ventilation slots 14 are provided on both the left and right sides of the charging shell 1, and circular ventilation slots 15 are provided on both the top and bottom sides of the charging shell 1. Filter screens 16 for filtering dust are laid on both the circular ventilation slots 15 and the square ventilation slots 14. The two square ventilation slots 14 form a channel to ensure the ventilation of the protective shell. At the same time, the filter screens 16 at the top effectively block external dust and rainwater, preventing excessive dust accumulation inside the charging shell 1.

[0049] A cooling fan 17 is rotatably connected to a fan bracket in the circular ventilation slot 15 located on the lower side of the charging housing 1. Sealing modules 18 for preventing water ingress are installed in the square ventilation slots 14 located on the left and right sides of the charging housing 1. A triangular ventilation bracket 19 is fixed to the upper end of the charging housing 1. When the transformer rotates, the cooling fan 17 rotates rapidly, generating upward airflow. This airflow from the cooling fan 17 creates a rapid airflow inside the charging housing 1, ensuring the transformer's heat dissipation efficiency. Simultaneously, the reciprocating rotation of the transformer ensures that every surface of the transformer can contact the airflow from the cooling fan 17, greatly improving heat dissipation efficiency.

[0050] See Figure 9 , Figure 10 and Figure 11 As shown, in order to improve the heat dissipation efficiency of the charging shell 1, a large number of slots are provided on the charging shell 1 for heat dissipation and ventilation. When the charging pile is not in use, in order to ensure the integrity of the charging pile, the square ventilation slot 14 can be opened and closed in an active manner. Specifically, the sealing module 18 includes hidden grooves on the left and right sides of the charging shell 1 and located at the upper end of the square ventilation slot 14. A sealing plate 180 for sealing the square ventilation slot 14 is slidably connected in the hidden groove. The sealing plate 180 can be opened and closed. When the charging pile is not in use, the sealing plate 180 is in a closed state. When the charging pile needs to be used, the sealing plate 180 on the square ventilation slot 14 is opened. At this time, the heat dissipation efficiency is improved through the square ventilation slot 14.

[0051] An opening and closing bracket 181 is fixedly installed on the lower end of the inner side of the sealing plate 180. An opening and closing spring 182 is fixedly installed on the lower end of the opening and closing bracket 181. An opening and closing plate 183 is fixedly connected to the lower end of the opening and closing spring 182. The opening and closing plate 183 is hinged to the sealing plate 180. A movable groove is provided on the front side of the sealing plate 180. A triangular snap-fit ​​plate 185 is fixedly installed in the movable groove by a snap-fit ​​spring 184. A snap-fit ​​block 186 is fixed on the upper end of the hidden groove corresponding to one side of the triangular snap-fit ​​plate 185. An unlocking rod 187 is slidably arranged on the front side of the charging shell 1 corresponding to the position of the triangular snap-fit ​​plate 185. An actuator plate 188 is symmetrically arranged on the left and right sides of the wire harness assembly block 350 corresponding to the position of the opening and closing plate 183. Specifically, in the initial state, the sealing plate 180 closes the square ventilation slot 14. When the charging pile is needed, the wire harness assembly block 350 on the fast heat sink 3 starts to rotate clockwise. The actuator plates 188 on both sides of the wire harness assembly block 350 press against the opening and closing plate 183 on the left side of the charging housing 1. At the same time, the opening and closing plate 183 is subjected to an upward external force, which drives the sealing plate 180 to move upward along the hidden groove until the triangular snap-fit ​​plate 185 on the side of the opening and closing plate 183 is inserted into the snap-fit ​​block 186. At this time, the triangular snap-fit ​​plate 185 passes through the snap-fit ​​block 186. The end of the movable space pops out from the movable groove on the opening and closing plate 183. Just as the length of the execution plate 188 is insufficient to support the opening and closing plate 183, the sealing plate 180 loses external force. At the same time, the sealing plate 180 enters the hidden groove through the cooperation of the triangular snap-fit ​​plate 185 and the snap-fit ​​block 186. At this time, the square ventilation slot 14 opens. Then, the above operation is repeated. When the wire harness assembly block 350 on the fast heat sink 3 rotates counterclockwise, the sealing plate 180 on the right side of the charging shell 1 opens, thereby realizing air convection and ensuring the efficiency of transformer heat dissipation.

[0052] See Figure 12 As shown, two symmetrical fixed columns 100 are rotatably connected to the middle of the inner side of the charging housing 1 via bearings. An electric fan 101 is fixed on the opposite sides of the fixed columns 100. A reciprocating gear 102 is fixed on the fixed column 100 located on the rear side of the charging housing 1. A reciprocating rack 103 is meshed on the side end of the reciprocating gear 102. A pressing plate 104 is fixed to the lower end of the reciprocating rack 103. A reciprocating spring 105 is fixed to the upper end of the reciprocating rack 103. The reciprocating spring 105 is fixed to the inner wall of the charging housing 1 via a horizontal plate 106.

[0053] Specifically, when the actuator plate 188 reciprocates, it intermittently compresses the pressing plate 104 at the lower end of the reciprocating rack 103. When the reciprocating rack 103 is subjected to upward compressive force, it moves upward and drives the reciprocating spring 105 to compress. When the pressing plate 104 loses external force, the reciprocating rack 103 moves downward due to the elastic force of the reciprocating spring 105, and then moves up and down. Simultaneously, the reciprocating rack 103 drives the reciprocating plate 104 at the lower end of the reciprocating rack 103 to compress. The meshing reciprocating gear 102 rotates, and when the reciprocating gear 102 rotates, it drives the fixed column 100 and the electric fan 101 fixed on it to swing left and right. During the left and right swinging process, the electric fan 101 swings and blows air on other components inside the charging shell 1 and located at the top of the transformer. Although the heat dissipation of other components is small, the electric fan 101 can further enable the other components to dissipate heat quickly. At the same time, the electric fan 101 can blow air on the charging shell 1, reduce the accumulation of dust inside it, and improve the heat dissipation efficiency.

[0054] Example 2: Based on Example 1, in order to ensure that the charging pile can be self-protected and avoid damage to its internal components such as transformers caused by vehicle impacts, and in areas where heavy rains are prone to cause road flooding, to prevent accidents caused by water leakage due to the charging pile, a lifting mechanism 4 is proposed to protect the charging pile.

[0055] See Figure 13 and Figure 14 As shown, the lifting mechanism 4 includes a vertical support frame 40 fixedly installed on the ground. Two symmetrical I-shaped guide blocks 41 are fixedly installed on the inner side of the vertical support frame 40. A limit groove is opened on the rear side of the charging shell 1. The I-shaped guide blocks 41 are slidably disposed in the limit groove. An anti-collision module 42 is provided on the I-shaped guide blocks 41. The charging shell 1 is slidably disposed on the vertical support frame 40, and the support base 2 at the lower end of the charging shell 1 is placed on the ground, while the vertical support frame 40 is fixed in the soil.

[0056] The anti-collision module 42 includes two symmetrical drive shafts 420 connected to the inner side of the I-shaped guide block 41 by bearings. Each drive shaft 420 is equipped with a first sprocket 421, and a first chain 422 is meshed on both first sprockets 421. The first chain 422 drives the two first sprockets 421 to rotate in the same direction.

[0057] A steering gear 423 is fixed to the side end of the first sprocket 421 located below the I-shaped guide block 41. A second gear 424 is meshed on the steering gear 423. The function of the steering gear 423 and the second gear 424 is to change the rotation direction of the first chain 422 and the second chain 427 so that the two rotate in opposite directions, thereby achieving the function of lifting the charging shell 1.

[0058] A second sprocket 425 is fixed to the side end of the second gear 424. A third sprocket 426 is set at the front end of the second sprocket 425. The second sprocket 425 and the third sprocket 426 are connected by a second chain 427. Both the second sprocket 425 and the third sprocket 426 are rotatably mounted on a horizontal frame 428. The horizontal frame 428 is fixed to the side wall of the vertical support frame 40. Two left-right symmetrical third gears 429 are fixed on the third sprocket 426 through a connecting shaft. A right-angled trapezoidal block 430 is meshed on the third gear 429. The lower end of the right-angled trapezoidal block 430 is set on the ground through a support spring 431. When installing the charging pile, a pit for the telescopic right-angled trapezoidal block 430 is dug in the ground in advance to ensure the safe operation of the entire charging pile.

[0059] A first gear 432 is fixed to the side end of the first sprocket 421. A lifting rack 433 is meshed on the first gear 432 and is fixed to the rear side wall of the charging housing 1.

[0060] Specifically, when the driver finds the charging station while the car needs to be charged, the car needs to be parked in the parking space. During the process of reversing into the parking space, the rear wheels of the car will be against the corner of the inclined surface of the right-angled trapezoidal block 430. At this time, the operator will feel the resistance of the rear wheels and perform the parking operation. Then, the operator will get out of the car and take out the charging gun from the charging station to charge the car.

[0061] However, when the car's battery is dead, the driver becomes anxious. If a mistake is made during the reversing maneuver, causing the car to continue reversing after just touching the inclined surface of the right-angled trapezoid block 430, the right-angled trapezoid block 430 will move downwards until the weight of the car exceeds the spring supporting the spring 431. At this point, the right-angled trapezoid block 430 will begin to dent into the ground. As it moves downwards, it drives the third gear 429 to rotate. The third gear 429, through the interaction of the second sprocket 425, the third sprocket 426, and the second chain 427, causes the second gear 429 to rotate. 4. When the gear rotates clockwise, the steering gear 423 meshing with the second gear 424 rotates counterclockwise. At the same time, the steering gear 423 rotates counterclockwise, and through the cooperation between the first chain 422 and the first sprocket 421, the first gear 432 rotates counterclockwise synchronously. Then, the first gear 432 lifts the rack 433, which drives the entire charging shell 1 to move upward along the I-shaped guide block 41 until the charging shell 1 is raised to a certain height, so that the main body of the charging shell 1 can avoid direct contact with the car. And if the vertical support frame 40 is knocked off course, it will not damage the main body of the charging shell 1, which greatly reduces the safety hazard.

[0062] See Figure 13 and Figure 14 As shown, a lifting motor 411 is fixed to the side end of the I-shaped guide block 41. The output end of the lifting motor 411 rotates through the I-shaped guide block 41 and is connected to the drive shaft 420. A sensing suspension ball 412 for sensing water depth is provided on the side wall of the charging shell 1. The lower side of the sensing suspension ball 412 abuts against the support base 2.

[0063] When the charging housing 1 is raised, the lifting motor 411 starts. The torque of the lifting motor 411 keeps the charging housing 1 in a raised state, preventing the right-angled trapezoidal block 430 from falling directly when it loses external force, thus avoiding secondary damage. When the car charging station is not in an accident, but the area where the charging station is installed is in a rainstorm, the inductive levitation ball 412 is initially suspended in the air, and the height of the suspension is adjusted to prevent the internal components of the housing from coming into contact with rainwater. If the rainstorm causes water to accumulate on the ground, the inductive levitation ball 412 begins to float upwards and remains floating on the water surface. At this time, the lifting motor 411 starts actively, directly driving the first gear 432 to rotate counterclockwise, thereby raising the charging housing 1 until the entire charging housing 1 and the support base 2 are on the water surface. This prevents the circuit from failing to trip in time, which could cause the charging housing 1 to leak high voltage and lead to a safety accident. Through the cooperation of the active and passive safety of the lifting mechanism 4, the safety of the charging station is greatly improved.

[0064] The implementation principle of this embodiment is as follows: (1): The transformer is supported by the clamping plate 340, and the limiting plate 341 on the clamping plate 340 is alternately aligned with and in contact with the heat sink on the transformer. Then, the four corners of the transformer are fixed by the right angle clamping block 343.

[0065] (2): After the transformer is fixed, pass one end of the wire connected to the transformer through the wire harness through hole 351 on the wire harness fixing block 352, and rotate the locking thread rod 353 to squeeze and fix the wire inside the wire harness through hole 351, so as to avoid poor contact between the terminal and the wire at the upper end when the transformer rotates.

[0066] (3): After the internal components and wires of the charging housing 1 are installed, the electric vehicle can be charged. During the charging process, the four planetary gears 32 of the cooling motor 30 rotate synchronously. During the rotation of the four planetary gears 32, the transformer rotates 360 degrees in both directions. When the transformer fixing module 34 rotates back and forth, it quickly dissipates heat from the working transformer. At the same time, the air circulation formed by the cooling fan 17 improves the heat dissipation efficiency. Furthermore, the reciprocating rotation of the transformer can prevent dust from accumulating on the surface of the transformer, ensuring the cleanliness of the transformer.

[0067] (4): When the driver finds the charging station while the car needs to be charged, the car needs to be parked in the parking space. During the reversing process, the rear wheels of the car are against the corner of the inclined surface of the right-angled trapezoidal block 430. At this time, the operator feels the resistance of the rear wheels and performs the parking operation. If a mistake is made during the reversing process, the car will not stop and will continue to reverse. At this time, the right-angled trapezoidal block 430 will move downward until the weight of the car exceeds the spring of the support spring 431. Then the right-angled trapezoidal block 430 will start to sink into the ground. Then, through the cooperation between multiple gears and sprockets, the first gear 432 will rotate counterclockwise and drive the entire charging shell 1 to move upward along the I-shaped guide block 41 by lifting the rack 433 until the charging shell 1 is raised to a certain height to avoid direct contact between the main body of the charging shell 1 and the car.

[0068] (5): When the car charging pile is not in an accident, but the area where the charging pile is installed is in a rainstorm, the induction suspension ball 412 is initially suspended in the air. If the rainstorm causes water to accumulate on the ground, the induction suspension ball 412 will float upward after being exposed to the rainwater and will always float on the water surface. At this time, the lifting motor 411 will start actively. The lifting motor 411 will directly drive the first gear 432 to rotate counterclockwise, thereby lifting the charging shell 1 upward until the entire charging shell 1 and the support base 2 are on the water surface. This will prevent the circuit from tripping in time, which could cause the charging shell 1 to leak high voltage and thus cause a safety accident. Through the cooperation of the active safety and passive safety of the lifting mechanism 4, the safety of the charging pile is greatly improved.
