Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging piles, and specifically refers to a new energy vehicle charging pile. Background Art

[0002] A new energy vehicle charging pile is a device that provides electrical energy for electric vehicles. It is divided into two types: an AC charging pile and a DC charging pile. The AC charging pile has a low power and is suitable for home use or long-term parking scenarios. The DC charging pile has a high power and is suitable for rapid charging.

[0003] When using a charging pile to charge a vehicle, in order to facilitate inserting the charging head into the vehicle's charging slot, the charging cable is usually set to be relatively long, which inevitably causes the charging cable to fall on the ground. The rolling of the vehicle and the immersion of rainwater will reduce the service life of the charging cable. To solve this problem, in the prior art, a winding device is set to wind up the charging cable, or the charging cable is suspended in mid-air to solve the problem of reduced service life; When the charging pile is charging, since the charging power gradually increases, the temperature of the equipment inside the charging pile rises. Generally, a heat dissipation component is set inside the charging pile, and ventilation holes for ventilation need to be opened on the outside of the charging pile. A filter screen will be set on the ventilation holes to block dust.

[0004] When using the charging cable to charge, it is necessary to pull the charging cable to insert the charging head into the charging slot. At this time, the charging cable is suspended in mid-air. Compared with the charging cable on the ground, although it prevents the rolling of the vehicle and the immersion of rainwater, in the case of pedestrians walking carelessly and the vehicle starting without unplugging the charging head, it will drive the charging cable to move together, which may cause the charging head to disengage from the charging slot and even cause the charging cable to break; Most of the time, the charging pile is in a standby state. The continuous opening and closing of the ventilation holes easily cause a lot of dust to cover the surface of the filter screen, resulting in less air entering the charging pile and poor heat dissipation effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a new energy vehicle charging pile.

[0006] To solve the above technical problem, the technical solution provided by the present invention is: a new energy vehicle charging pile, including a charging pile, a charging cable is provided on one side of the charging pile, a charging head is provided at one end of the charging cable, a bracket is slidably provided on the charging pile, a guide roller is slidably provided on the bracket, the charging cable is arranged on the guide roller, a rotating rod is rotatably provided on the guide roller, an extension rod is slidably provided on the rotating rod, a connecting column is ball-jointed on the extension rod, a circular ring is provided on the charging cable, the other end of the connecting column is ball-jointed with the circular ring, and a control mechanism for controlling the sliding of the guide roller is provided on the bracket; A sliding rod is slidably arranged on the charging pile, and a transmission mechanism for driving the sliding rod to move upward when the bracket moves downward is arranged between the sliding rod and the bracket. A plurality of air inlets and air outlets are respectively arranged on both sides of the charging pile. A rotating shaft I and a rotating shaft II are respectively rotatably arranged on the air inlet and the air outlet. A filter screen is arranged on the rotating shaft I. A baffle I is slidably arranged on the charging pile at the air inlet. A baffle II is arranged on the rotating shaft II. The upward movement of the sliding rod drives the rotating shaft I and the rotating shaft II to rotate, thereby changing the opening and closing of the air inlet and the air outlet.

A first return spring is arranged between the plug post and the fixed block. The bracket includes a U-shaped rod slidably arranged on the charging pile. A sliding column is fixedly arranged on the U-shaped rod. The guide roller is slidably arranged on the sliding column, and a clamping groove is formed on the sliding column. The downward movement of the plug post can abut against the clamping groove to limit the movement of the guide roller.

[0008] As an improvement, the control mechanism further includes a driving block and an arc-shaped plate. The driving block slides radially on one side of the guide roller. The arc-shaped plate is hinged on the driving block, and the other end of the arc-shaped plate is hinged to the plug post. A pushing block is arranged on one side of the rotating rod. A rotating hole matching with the pushing block is arranged on the guide roller. Both ends of the pushing block are arc-shaped surfaces.

[0009] As an improvement, a triangular clamping block is arranged at one end of the plug post, and a triangular groove matching with the triangular clamping block is arranged in the clamping groove. Whether the triangular clamping block fits with the triangular groove controls the movement of the guide roller.

[0010] As an improvement, the transmission mechanism includes a sliding groove on the charging pile. The bracket and the sliding rod are respectively slidably arranged at the upper end and the lower end of the sliding groove. Transmission wheels are rotatably arranged at both ends of the sliding groove. A transmission belt is arranged between the two transmission wheels. The transmission belts on both sides of the transmission wheels are respectively fixedly connected with the bracket and the sliding rod.

[0011] As an improvement, a rotating mechanism for driving the rotating shaft I and the rotating shaft II to rotate when the sliding rod moves upward is arranged on one side of the charging pile. The rotating mechanism includes gears I arranged at the ends of the rotating shaft I and the rotating shaft II. Synchronous belts are wound around the gears I on the same side. A connecting rod is arranged on the sliding rod. A dial rod is rotatably arranged on the connecting rod, and a torsion spring is arranged on the rotating shaft of the dial rod. A fixing rod is arranged on the synchronous belt. The up and down movement of the dial rod abuts against the fixing rod to drive the fixing rod to move, and the dial rod can rotate over the fixing rod.

[0012] As an improvement, a cleaning mechanism for cleaning the surface of the filter screen is arranged on the charging pile. The cleaning mechanism includes a brush slidably arranged on the filter screen. A shielding plate is arranged above the air inlet on the charging pile. A driving rod is slidably arranged on the shielding plate. After the filter screen moves along the circumference of the rotating shaft I, it is clamped with the driving rod. The movement of the driving rod drives the brush to move on the filter screen.

[0013] As an improvement, a clamping plate is provided on the brush, an arc-shaped block is provided on the clamping plate, an arc-shaped groove cooperating with the arc-shaped block is provided on the driving rod, and a synchronizing rod is provided between adjacent driving rods.

[0014] As an improvement, a buffer block is slidably provided in the sliding groove, a spring is provided between the buffer block and the bottom surface of the sliding groove, a first rack is provided on the buffer block, a second gear meshing with the first rack is rotatably provided on the charging pile, an L-shaped rod is slidably provided on the charging pile, a connecting plate is provided between two adjacent first baffles, one end of the L-shaped rod is fixedly connected to one of the first baffles, and a second rack meshing with the second gear is provided at the other end of the L-shaped rod.

[0015] The advantages of the present invention compared with the prior art are as follows: 1. By providing a bracket, a sliding rod, a transmission mechanism and a guide roller, the charging cable can be placed on the guide roller so that the charging cable is always in the air. By providing a rotating rod, an extension rod, a connecting column and a ring, the control mechanism controls the sliding of the rotating rod and the extension rod, which can protect the charging cable and facilitate the adjustment of charging. When a pedestrian walks by, the pedestrian will contact the rotating rod and the extension rod. Since the rotating rod cannot move in the direction of the pedestrian, the charging cable can be prevented from moving. When the car starts without unplugging the charging head, the car drives the charging cable to move. When the extension rod slides to one end of the rotating rod, the extension rod no longer slides. When the car continues to move, the charging head will be detached from the charging slot, thus effectively protecting the charging cable and preventing the charging cable from disconnecting from the connection position with the charging pile. 2. By providing a first rotating shaft, a second rotating shaft, a first baffle, a second baffle and a filter screen, when not charging, the first baffle and the second baffle will block the air inlet and the air outlet. At this time, the filter screen is located outside the charging pile. By providing a shielding plate, dust in the air can be prevented from falling on the filter screen. 3. By providing a rotatable filter screen, when the charging pile is not dissipating heat, the filter screen is located outside. The cleaning mechanism can facilitate the cleaning of the surface of the filter screen. Since the filter screen is outside, the dust generated during the cleaning process will not enter the charging pile. The setting of the first baffle and the second baffle can prevent water vapor in a humid environment from entering the charging pile. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Combined with the attached Figure 1 , attached Figure 2 , attached Figure 3 As shown in the figures, a charging pile for a new energy vehicle includes a charging pile 1. One side of the charging pile 1 is provided with a charging cable 11, and one end of the charging cable 11 is provided with a charging head 12. A bracket 2 is slidably arranged on the charging pile 1. Two inclined plates 26 arranged obliquely are provided on the bracket 2 on one side of the charging pile 1. One ends of the two inclined plates 26 are fixedly connected. A guide roller 21 is slidably arranged on the bracket 2. The charging cable 11 is arranged on the guide roller 21. Two return springs II 28 are provided on the bracket 2 on both sides of the guide roller 21. One end of each return spring II 28 is provided with a sliding ring 29, and the sliding ring 29 abuts against the guide roller 21. A rotating rod 22 is rotatably arranged on the guide roller 21. An extension rod 23 is slidably arranged on the rotating rod 22. A connecting column 24 is ball-jointed on the extension rod 23. A ring 25 is arranged on the charging cable 11. The other end of the connecting column 24 is ball-jointed with the ring 25. A control mechanism 27 for controlling the sliding of the guide roller 21 is arranged on the bracket 2; A sliding rod 3 is slidably arranged on the charging pile 1. A transmission mechanism 4 for driving the sliding rod 3 to move upward when the bracket 2 moves downward is arranged between the sliding rod 3 and the bracket 2. A plurality of air inlets 5 and air outlets 6 are respectively arranged on both sides of the charging pile 1. A rotating shaft I 7 and a rotating shaft II 71 are respectively rotatably arranged on the air inlets 5 and the air outlets 6. A filter screen 73 is arranged on the rotating shaft I 7. A baffle I 72 is slidably arranged on the charging pile 1 at the air inlet 5. A baffle II 74 is arranged on the rotating shaft II 71. A magnetic attraction block 87 magnetically attracted to the baffle II 74 is arranged on the charging pile 1. The upward movement of the sliding rod 3 drives the rotating shaft I 7 and the rotating shaft II 71 to rotate, thereby changing the opening and closing of the air inlets 5 and the air outlets 6.

[0031] Working principle of the present invention: In the initial state, the second reset spring 28 is in a relaxed state. When charging the vehicle, hold the charging head 12 and then pull the charging cable 11 towards the vehicle. At this time, the charging cable 11 drives the bracket 2 to move downward. At the same time, the charging cable 11 changes from being perpendicular to the ground to having a certain angle with the ground, so that the rotating rod 22 rotates. Since the charging cable 11 is pulled, the charging cable 11 on the side of the charging head 12 becomes longer, thereby driving the extension rod 23 to slide on the rotating rod 22. The bracket 2 drives the sliding rod 3 to move upward through the transmission mechanism 4. The upward movement of the sliding rod 3 drives the rotating mechanism 8 and the cleaning mechanism 9. The rotating mechanism 8 drives the first rotating shaft 7 and the second rotating shaft 71 to rotate. The first rotating shaft 7 drives the filter screen 73 to rotate, and the first baffle 72 slides downward. After the rotation is completed, the filter screen 73 is located in the air inlet 5. The second rotating shaft 71 drives the second baffle 74 to rotate, and the second baffle 74 no longer blocks the air outlet 6. During the rotation of the rotating rod 22, the rotating rod 22 drives the control mechanism 27, and the control mechanism 27 releases the fixation of the guide roller 21. Therefore, when the charging cable 11 is pulled, the guide roller 21 will slide towards the vehicle charging slot. One of the second reset springs 28 is compressed, and then the control mechanism 27 fixes the guide roller 21. Then insert the charging head 12 into the charging slot to start charging; After charging is completed, unplug and release the charging head 12. The sliding rod 3 moves downward under the action of gravity. Through the transmission mechanism 4, the bracket 2 moves upward. The upward movement of the bracket 2 drives the charging cable 11 to move upward. The charging cable 11 changes from having a certain angle with the ground to being perpendicular to the ground under the action of gravity, thereby driving the rotating rod 22 to rotate. Since the charging cable 11 on the side of the charging head 12 becomes shorter, the extension rod 23 is driven to slide. The rotation of the rotating rod 22 drives the control mechanism 27, and the control mechanism 27 releases the fixation of the guide roller 21. The second reset spring 28 pushes the guide roller 21 to reset. The downward movement of the sliding rod 3 drives the rotating mechanism 8 and the cleaning mechanism 9. The rotating mechanism 8 rotates the first rotating shaft 7 and the second rotating shaft 71, the filter screen 73 rotates, the second baffle 74 blocks the air outlet 6, and the first baffle 72 slides to block the air inlet 5. The cleaning mechanism 9 can clean the dust on the surface of the filter screen 73.

[0032] Combined with attached Figure 3 、attached Figure 4 、attached Figure 5 、attached Figure 6 As shown in, the control mechanism 27 includes a fixing block 271 arranged on the guide roller 21 and a plug post 272 movably adjusted on the fixing block 271. A first reset spring 273 is arranged between the plug post 272 and the fixing block 271. The bracket 2 includes a U-shaped rod 211 slidably arranged on the charging pile 1. A sliding column 212 is fixedly arranged on the U-shaped rod 211. The guide roller 21 is slidably arranged on the sliding column 212, and a clamping groove 274 is formed on the sliding column 212. The downward movement of the plug post 272 can abut against the clamping groove 274 to limit the movement of the guide roller 21; The control mechanism 27 further includes a driving block 277 and an arc-shaped plate 278. The driving block 277 is slidably arranged on one side of the guiding roller 21. The arc-shaped plate 278 is hinged to the driving block 277, and the other end of the arc-shaped plate 278 is hinged to the inserting post 272. A pushing block 279 is arranged on one side of the rotating rod 22. A rotating hole cooperating with the pushing block 279 is arranged on the guiding roller 21. Both ends of the pushing block 279 are arc-shaped surfaces. One end of the inserting post 272 is provided with a triangular clamping block 275. A triangular groove 276 cooperating with the triangular clamping block 275 is arranged in the clamping groove 274. Whether the triangular clamping block 275 is in contact with the triangular groove 276 controls the movement of the guiding roller 21.

[0033] Working principle of the control mechanism 27: In the initial state, the first reset spring 273 is in a relaxed state. Pull the charging cable 11 to change the angle between the charging cable 11 and the ground from perpendicular to having a certain angle with the ground, so that the rotating rod 22 rotates. The rotating rod 22 drives the pushing block 279. The pushing block 279 moves along the rotating hole to contact the driving block 277 and drives the driving block 277 to slide radially. The sliding of the driving block 277 drives the arc-shaped plate 278 to rotate and move. The arc-shaped plate 278 drives the inserting post 272 to move. The inserting post 272 drives the triangular clamping block 275 to move away from the triangular groove 276, and the first reset spring 273 is compressed. At this time, the guiding roller 21 can slide. Without changing the angle between the charging cable 11 and the ground, pull the charging cable 11 until the guiding roller 21 slides to near the vehicle charging slot and then stop. Then continue to pull the charging cable 11 until the charging cable 11 is located at the vehicle charging slot. During the pulling process, the rotating rod 22 continues to rotate. When the pushing block 279 is no longer in contact with the driving block 277, the first reset spring 273 pushes the inserting post 272 to move. The inserting post 272 drives the triangular clamping block 275 to fit with the triangular groove 276, and the arc-shaped plate 278 and the driving block 277 are reset. At this time, the guiding roller 21 is fixed.

[0034] Combined with the attached Figure 2 、attached Figure 3 、attached Figure 7 As shown in the attached figures, the transmission mechanism 4 includes a sliding groove 41 on the charging pile 1. The bracket 2 and the sliding rod 3 are respectively slidably arranged at the upper end and the lower end of the sliding groove 41. Transmission wheels 42 are rotatably arranged at both ends of the sliding groove 41. A transmission belt 43 is arranged between the two transmission wheels 42. The transmission belts 43 on both sides of the transmission wheels 42 are respectively fixedly connected to the bracket 2 and the sliding rod 3.

[0035] Working principle of the transmission mechanism 4: Pull the charging cable 11. The charging cable 11 drives the bracket 2 to move downward. The downward movement of the bracket 2 drives the transmission belt 43 on one side to move downward. Under the action of the two transmission wheels 42, the downward movement of the transmission belt 43 on one side drives the transmission belt 43 on the other side to move upward, thereby driving the sliding rod 3 to move upward.

[0036] Combined with the attached Figure 3 、attached Figure 8 、attached Figure 9 、attachedFigure 10 As shown, a rotating mechanism 8 is provided on one side of the charging pile 1, which drives the rotation of the first rotating shaft 7 and the second rotating shaft 71 when the sliding rod 3 moves upward. The rotating mechanism 8 includes a first gear 81 provided at the ends of the first rotating shaft 7 and the second rotating shaft 71. A synchronous belt 82 is wound around the first gears 81 on the same side. A connecting rod 83 is provided on the sliding rod 3. A lever 84 is rotatably provided on the connecting rod 83, and a torsion spring 85 is provided on the rotating shaft of the lever 84. A fixing rod 86 is provided on the synchronous belt 82. The lever 84 moves up and down to abut against the fixing rod 86 to drive the fixing rod 86 to move, and the lever 84 can rotate over the fixing rod 86.

[0037] Working principle of the rotating mechanism 8: In the initial state, the torsion spring 85 is in a relaxed state. In order to make the first rotating shafts 7 and the second rotating shafts 71 rotate simultaneously, the first gears 81 and the synchronous belt 82 are provided. Thus, the movement of the fixing rod 86 drives the synchronous belt 82 to move, and the synchronous belt 82 drives multiple first gears 81 to rotate simultaneously. Since the first rotating shaft 7 and the second rotating shaft 71 need to rotate reciprocally, the synchronous belt 82 also needs to move up and down reciprocally. By providing a rotatable lever 84, it can rotate over the fixing rod 86 after driving the fixing rod 86 to move a certain distance. Specifically, the movement of the sliding rod 3 drives the lever 84. The lever 84 moves to contact the fixing rod 86, and then the lever 84 continues to move and drives the fixing rod 86 to move. The fixing rod 86 drives the synchronous belt 82 to move, and the synchronous belt 82 drives the first gears 81 to rotate. The first gears 81 respectively drive the first rotating shaft 7 and the second rotating shaft 71 to rotate, thereby driving the baffle 72 and the filter screen 73 on the first rotating shaft 7 and the baffle 74 on the second rotating shaft 71 to move along the circumference. The baffle 74 can be fixed by the magnetic attraction block 87. Then the sliding rod 3 continues to move. Since the fixing rod 86 no longer moves, it forces the lever 84 to rotate downward, and the torsion spring 85 twists. When the fixing rod 86 no longer contacts the lever 84, the torsion spring 85 drives the lever 84 to rotate and reset.

[0038] Combined with the attached Figure 3 、attached Figure 9 、attached Figure 10 、attached Figure 11 、attached Figure 12 As shown, a cleaning mechanism 9 for cleaning the surface of the filter screen 73 is provided on the charging pile 1. The cleaning mechanism 9 includes a brush 91 slidably arranged on the filter screen 73. A shielding plate 910 is provided on the charging pile 1 above the air inlet 5. A driving rod 93 is slidably arranged on the shielding plate 910. After the filter screen 73 moves along the circumference of the first rotating shaft 7, it is clamped with the driving rod 93. The movement of the driving rod 93 drives the brush 91 to move on the filter screen 73; A clamping plate 94 is provided on the brush 91, and an arc-shaped block 95 is provided on the clamping plate 94. An arc-shaped groove 96 cooperating with the arc-shaped block 95 is provided on the driving rod 93. A synchronous rod 97 is provided between adjacent driving rods 93.

[0039] Working principle of the cleaning mechanism 9: When the charging pile 1 is in an unused state and the filter screen 73 needs to be cleaned, since the brush 91 is slidably arranged on the filter screen 73 and the filter screen 73 is rotatable, in order to ensure that the brush 91 can be driven by the driving rod 93 after rotation, an arc-shaped block 95 and an arc-shaped groove 96 are provided. After the filter screen 73 rotates, the arc-shaped block 95 on it enters the arc-shaped groove 96, so that the driving rod 93 can drive the brush 91 to move and clean the dust on the surface of the filter screen 73. Specifically, when the charging pile 1 is in an unused state, at this time the filter screen 73 is in a horizontal state and the arc-shaped block 95 on the clamping plate 94 is located in the arc-shaped groove 96. Then, the synchronous rod 97 is pulled. The synchronous rod 97 drives the driving rod 93, and the driving rod 93 drives the brush 91 to move until the brush 91 disengages from the filter screen 73. At this time, the dust is swept off. Then, the synchronous rod 97 is pushed to reset the brush 91.

[0040] Combined with the attached Figure 3 、attached Figure 9 、attached Figure 10 As shown, a buffer block 99 is slidably arranged in the sliding groove 41 and a spring is provided between the buffer block 99 and the bottom surface of the sliding groove 41. A first rack 911 is provided on the buffer block 99. A second gear 912 meshing with the first rack 911 is rotatably arranged on the charging pile 1. An L-shaped rod 98 is slidably arranged on the charging pile 1. A connecting plate 92 is provided between two adjacent first baffles 72. One end of the L-shaped rod 98 is fixedly connected to one of the first baffles 72, and a second rack 913 meshing with the second gear 912 is provided at the other end of the L-shaped rod 98; The specific shape of the first baffle 72 is a vertically Z-shaped plate; A connecting column is provided under the sliding rod 3, and a counterweight is provided on the connecting column.

[0041] Working principle: To prevent the sliding rod 3 from hitting the inner wall of the sliding groove 41 too quickly when moving downward, a buffer block 99 and a spring are arranged in the sliding groove 41, so as to relieve the falling speed of the sliding rod 3. Since the buffer block 99 needs to move the first baffle 72 upward when moving downward, in order to move the first baffle 72 upward, a first rack 911, a second gear 912 and a second rack 913 are arranged. When the first rack 911 moves downward, driven by the second gear 912, the moving direction of the second rack 913 is upward. Since the filter screen 73 needs to rotate first, the fixing rod 86 is arranged above the buffer block 99. Specifically, when charging is required, the sliding rod 3 moves upward, the spring pushes the buffer block 99 upward, the buffer block 99 drives the first rack 911 upward, the first rack 911 drives the second gear 912 to rotate, the second gear 912 drives the second rack 913 to move downward, the second rack 913 drives the connecting plate 92 to move downward, the connecting plate 92 drives the first baffle 72 to move downward, and the first baffle 72 no longer blocks the air inlet 5. Then the sliding rod 3 drives the rotating mechanism 8, and the rotating mechanism 8 drives the filter screen 73 to rotate so that the filter screen 73 is located in the air inlet 5. When not charging, the sliding rod 3 first drives the rotating mechanism 8 to make the filter screen 73 no longer located in the air inlet 5, and then drives the buffer block 99 to move downward. The buffer block 99 drives the first baffle 72 to move upward through the first rack 911, the second gear 912 and the second rack 913 to block the air inlet 5; Since a part of the filter screen 73 will be located in the air inlet 5 when the filter screen 73 is in a horizontal state, in order to ensure that the first baffle 72 completely seals the air inlet 5, the first baffle 72 is set as a Z-shaped plate, and one end of the first baffle 72 abuts against the end of the filter screen 73.

[0042] In specific use, it is necessary to first pull the charging cable 11 to change its state from perpendicular to the ground to a certain angle, so as to release the fixation of the control mechanism 27 on the guide roller 21. Then, while maintaining the angle, pull the charging cable 11 to make the charging cable 11 close to the vehicle charging slot. After that, continue to pull the charging cable 11 to change the angle between the charging cable 11 and the ground to fix the control mechanism 27 on the guide roller 21. After charging is completed, just unplug the charging head 12 and release it. The cleaning mechanism 9 can be used regularly to clean the surface of the filter screen 73.
