Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging piles, and in particular to a new energy automobile charging pile. Background Art

[0002] New energy vehicle charging piles are devices that provide electricity for electric vehicles. They are divided into two types: AC charging piles and DC charging piles. AC charging piles have low power and are suitable for home or long-term parking scenarios. DC charging piles have high power and are suitable for quick charging.

[0003] When using a charging station to charge a car, the charging cable is usually set longer to facilitate the insertion of the charging head into the car's charging slot. This inevitably causes the charging cable to fall to the ground. The rolling of the car and the soaking of the charging cable by rain will shorten the service life of the charging cable. To solve this problem, the existing technology uses a winding device to wind up the charging cable, or suspends the charging cable so that it is in mid-air, thereby solving the problem of shortened service life.

[0004] When charging at a charging pile, the charging power gradually increases and the temperature of the equipment inside the charging pile rises. Generally, a heat dissipation component is installed inside the charging pile, and ventilation holes are required on the outside of the charging pile for ventilation. Filters are installed in the ventilation holes to block dust.

[0005] When charging with a charging cable, you need to pull the charging cable to insert the charging head into the charging slot. At this time, the charging cable is suspended in the air. Compared with the charging cable on the ground, although it prevents cars from running over it and soaking it in rain, if pedestrians walk carelessly or start the car with the charging head not unplugged, the charging cable will move with it, which may cause the charging head to fall out of the charging slot or even cause the charging cable to break.

[0006] The charging pile is in standby mode most of the time. If the ventilation holes are opened and closed all the time, the filter surface will be covered with a lot of dust, resulting in less air entering the charging pile and poor heat dissipation effect. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the above difficulties and provide a new energy vehicle charging pile.

[0008] To solve the above technical problems, the present invention provides a technical solution as follows: a new energy vehicle charging pile, comprising a charging pile, a charging cable provided on one side of the charging pile, a charging head provided at one end of the charging cable, a bracket provided on the charging pile for sliding movement, a guide roller provided on the bracket for sliding movement, the charging cable provided on the guide roller, a rotating rod provided on the guide roller for rotation, an extension rod provided on the rotating rod for sliding movement, a connecting column provided on a ball joint on the extension rod, a circular ring provided on the charging cable, the other end of the connecting column being spherically hinged with the circular ring, and a control mechanism for controlling the sliding movement of the guide roller provided on the bracket;

[0011] As an improvement, the control mechanism also includes a driving block and an arc plate. The driving block slides radially on one side of the guide roller. The arc plate is hinged on the driving block. The other end of the arc plate is hinged to the plug column. A push block is provided on one side of the rotating rod. A rotating hole that cooperates with the push block is provided on the guide roller. Both ends of the push block are arc surfaces.

[0012] As an improvement, a triangular clamping block is provided at one end of the plug post, and a triangular groove cooperating with the triangular clamping block is provided in the clamping slot. Whether the triangular clamping block fits with the triangular groove controls the movement of the guide roller.

[0013] As an improvement, the transmission mechanism includes a slide groove on the charging pile, and the bracket and the slide rod are respectively slidably arranged at the upper and lower ends of the slide groove. Transmission wheels are rotatably provided at both ends of the slide groove, and a transmission belt is provided between the two transmission wheels. The transmission belts located on both sides of the transmission wheel are fixedly connected to the bracket and the slide rod respectively.

[0014] As an improvement, a rotating mechanism is provided on one side of the charging pile, which drives the sliding rod to move upward to drive the rotating shaft one and the rotating shaft two to rotate. The rotating mechanism includes gear one arranged at the end of the rotating shaft one and the rotating shaft two, and a synchronous belt is wound around the gear one on the same side. A connecting rod is provided on the sliding rod, and a shift rod is provided on the connecting rod for rotation, and a torsion spring is provided on the rotating shaft of the shift rod. A fixed rod is provided on the synchronous belt, and the shift rod moves up and down to abut the fixed rod to drive the fixed rod to move, and the shift rod can rotate over the fixed rod.

[0015] As an improvement, the charging pile is provided with a cleaning mechanism for cleaning the surface of the filter, and the cleaning mechanism includes a brush slidably arranged on the filter. A baffle is provided on the charging pile above the air inlet, and a drive rod is slidably arranged on the baffle. The filter moves in a circle along the rotating shaft and then engages with the drive rod. The movement of the drive rod drives the brush to move on the filter.

[0016] As an improvement, the brush is provided with a clamping plate, the clamping plate is provided with an arc block, the driving rod is provided with an arc groove that matches the arc block, and a synchronization rod is provided between adjacent driving rods.

[0017] As an improvement, a buffer block is provided for sliding in the slide groove and a spring is provided between the buffer block and the bottom surface of the slide groove, a rack 1 is provided on the buffer block, a gear 2 is rotatably provided on the charging pile and meshes with the rack 1, an L-shaped rod is provided for sliding on the charging pile, a connecting plate is provided between two adjacent baffles 1, one end of the L-shaped rod is fixedly connected to one of the baffles 1, and the other end of the L-shaped rod is provided with a rack 2 meshing with the gear 2.

[0018] The advantages of the present invention compared with the prior art are:

[0019] 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, a control mechanism controls the sliding of the rotating rod and the extension rod, which can protect the charging cable while facilitating the adjustment of charging. When pedestrians walk by, they will come into contact with 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 charging head is not unplugged and the car is started, the car drives the charging cable to move. When the extension rod slides to one end of the rotating rod, the extension rod stops sliding. The continued movement of the car will cause the charging head to detach from the charging slot, thereby effectively protecting the charging cable and preventing the charging cable from being disconnected from the connection position with the charging pile.

[0020] By setting the rotating shaft 1, rotating shaft 2, baffle 1, baffle 2 and filter, when not charging, baffle 1 and baffle 2 will block the air inlet and outlet. At this time, the filter is located outside the charging pile. The baffle can prevent dust in the air from falling on the filter.

[0021] By setting a rotatable filter, when the charging pile is not dissipating heat, the filter is located on the outside. Setting a cleaning mechanism can facilitate cleaning of the filter surface. Since the filter is on the outside, dust generated during the cleaning process will not enter the charging pile. The setting of baffle one and baffle two can prevent water vapor in a humid environment from entering the charging pile. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A sliding rod 3 is provided on the charging pile 1 for sliding, and a transmission mechanism 4 is provided between the sliding rod 3 and the bracket 2 for sliding the bracket 2 down and driving the sliding rod 3 to move up. A plurality of air inlets 5 and air outlets 6 are provided on both sides of the charging pile 1, and a rotating shaft 1 7 and a rotating shaft 2 71 are respectively provided for rotating on the air inlet 5 and the air outlet 6, and a filter 73 is provided on the rotating shaft 1 7. A baffle 1 72 is provided for sliding at the air inlet 5 on the charging pile 1, and a baffle 2 74 is provided on the rotating shaft 2 71. A magnetic block 87 that is magnetically attracted to the baffle 2 74 is provided on the charging pile 1. The sliding rod 3 moves upward to drive the rotating shaft 1 7 and the rotating shaft 2 71 to rotate so that the air inlet 5 and the air outlet 6 are opened.

[0038] The working principle of the present invention is as follows: in the initial state, the return spring 28 is in a relaxed state. When the car needs to be charged, the charging head 12 is held and the charging line 11 is pulled toward the car. At this time, the charging line 11 drives the bracket 2 to move downward. At the same time, the charging line 11 changes from being perpendicular to the ground to having a certain angle with the ground, so that the rotating rod 22 rotates. Due to the pulling of the charging line 11, the charging line 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 slide rod 3 to move upward through the transmission mechanism 4. The upward movement of the slide rod 3 drives the rotating mechanism 8 and the cleaning mechanism 9. The rotating mechanism 8 drives the rotating shaft 1 7 and shaft 2 71 rotate, shaft 1 7 drives filter 73 to rotate, baffle 1 72 slides downward, after the rotation is completed, filter 73 is in air inlet 5, shaft 2 71 drives baffle 2 74 to rotate, baffle 2 74 no longer blocks air outlet 6, during the rotation of rotating rod 22, rotating rod 22 drives control mechanism 27, control mechanism 27 releases the fixation of guide roller 21, so that when charging line 11 is pulled, guide roller 21 will slide toward the direction of car charging slot, one of return springs 28 is compressed, and then control mechanism 27 fixes guide roller 21, and then charging head 12 is inserted into charging slot to start charging;

[0039] After charging is completed, unplug and release the charging head 12, and the slide bar 3 moves downward under the action of gravity, and the bracket 2 moves upward through the transmission mechanism 4. The upward movement of the bracket 2 drives the charging cable 11 to move upward. Under the action of gravity, the charging cable 11 changes from a certain angle to the ground to perpendicular to the ground, thereby driving the rotating rod 22 to rotate. Since the charging cable 11 on the side of the charging head 12 becomes shorter, it drives the extension rod 23 to slide, and the rotation of the rotating rod 22 drives the control mechanism 27. The control mechanism 27 releases the fixation of the guide roller 21, and the reset spring 28 pushes the guide roller 21 to reset. The slide bar 3 moves downward to drive the rotating mechanism 8 and the cleaning mechanism 9. The rotating mechanism 8 rotates the rotating shaft 7 and the rotating shaft 2 71, and the filter 73 rotates. The baffle 2 74 blocks the air outlet 6, and the baffle 1 72 slides to block the air inlet 5. The cleaning mechanism 9 can clean the dust on the surface of the filter 73.

[0040] Combined with attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 As shown, the control mechanism 27 includes a fixed block 271 provided on the guide roller 21 and a plug 272 movably adjusted on the fixed block 271. A return spring 273 is provided between the plug 272 and the fixed block 271. The bracket 2 includes a U-shaped rod 211 slidably provided on the charging pile 1. A sliding column 212 is fixedly provided on the U-shaped rod 211. The guide roller 21 is slidably provided on the sliding column 212, and a slot 274 is provided on the sliding column 212. When the plug 272 moves downward, it can abut against the slot 274, thereby limiting the movement of the guide roller 21.

[0041] 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 guide roller 21. The arc-shaped plate 278 is hinged on the driving block 277. The other end of the arc-shaped plate 278 is hinged to the plug post 272. A push block 279 is provided on one side of the rotating rod 22. A rotating hole that cooperates with the push block 279 is provided on the guide roller 21. Both ends of the push block 279 are arc-shaped surfaces.

[0042] A triangular block 275 is provided at one end of the plug post 272 , and a triangular groove 276 is provided in the groove 274 to cooperate with the triangular block 275 . Whether the triangular block 275 fits the triangular groove 276 controls the movement of the guide roller 21 .

[0043] Working principle of control mechanism 27: In the initial state, the return spring 273 is in a relaxed state, pulling the charging line 11, so that the charging line 11 changes from being perpendicular to the ground to having a certain angle with the ground, thereby rotating the rotating rod 22, and the rotating rod 22 drives the push block 279, which moves along the rotating hole and contacts the driving block 277 and drives the driving block 277 to slide radially. The sliding of the driving block 277 drives the arc plate 278 to rotate and move, and the arc plate 278 drives the plug 272 to move. The plug 272 drives the triangular block 275 away from the triangular groove 276, and the return spring 273 is compressed. At this time, the guide roller 21 can slide. Without changing the angle between the charging cable 11 and the ground, the charging cable 11 is pulled so that the guide roller 21 slides to the vicinity of the car charging slot and stops. Then, the charging cable 11 is continued to be pulled so that the charging cable 11 is located at the car charging slot. During the pulling process, the rotating rod 22 continues to rotate. At this time, when the push block 279 is no longer in contact with the driving block 277, the reset spring 273 pushes the plug post 272 to move. The plug post 272 drives the triangular clamping block 275 to fit with the triangular groove 276, and the arc plate 278 and the driving block 277 are reset. At this time, the guide roller 21 is fixed.

[0044] Combined with attachment Figure 2 , Attachment Figure 3 , Attachment Figure 7 As shown, the transmission mechanism 4 includes a slide groove 41 on the charging pile 1, and the bracket 2 and the slide rod 3 are respectively slidably arranged at the upper and lower ends of the slide groove 41. Transmission wheels 42 are rotatably provided at both ends of the slide groove 41, and a transmission belt 43 is provided between the two transmission wheels 42. The transmission belts 43 located on both sides of the transmission wheel 42 are fixedly connected to the bracket 2 and the slide rod 3 respectively.

[0045] The working principle of the transmission mechanism 4 is as follows: when the charging cable 11 is pulled, the charging cable 11 drives the bracket 2 to move downward, and 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 transmission belt 43 on one side moves downward, driving the transmission belt 43 on the other side to move upward, thereby driving the slide bar 3 to move upward.

[0046] Combined with attachment Figure 3 , Attachment Figure 8 , Attachment Figure 9 , Attachment Figure 10 As shown, a rotating mechanism 8 is provided on one side of the charging pile 1 for moving the slide bar 3 upward to drive the rotating shaft 1 7 and the rotating shaft 2 71 to rotate. The rotating mechanism 8 includes a gear 1 81 arranged at the ends of the rotating shaft 1 7 and the rotating shaft 2 71. A synchronous belt 82 is wound around the gear 1 81 on the same side. A connecting rod 83 is provided on the slide bar 3. A shift lever 84 is rotatably provided on the connecting rod 83, and a torsion spring 85 is provided on the rotating shaft of the shift lever 84. A fixed rod 86 is provided on the synchronous belt 82. The shift lever 84 moves up and down to abut against the fixed rod 86 to drive the fixed rod 86 to move, and the shift lever 84 can rotate over the fixed rod 86.

[0047] Working principle of the rotating mechanism 8: In the initial state, the torsion spring 85 is in a relaxed state. In order to make multiple rotating shafts 1 7 and 2 71 rotate at the same time, a gear 1 81 and a synchronous belt 82 are provided, so that the fixed rod 86 moves to drive the synchronous belt 82 to move, and the synchronous belt 82 drives multiple gears 1 81 to rotate at the same time. Since the rotating shaft 1 7 and the rotating shaft 2 71 need to rotate back and forth, the synchronous belt 82 also needs to move up and down. By providing a rotatable lever 84, the fixed rod 86 can be driven to move a certain distance and then pass over the fixed rod 86. Specifically, the sliding rod 3 moves to drive the lever 84, and the lever 84 moves to contact the fixed rod 86, and then The shift rod 84 continues to move and drives the fixed rod 86 to move, the fixed rod 86 drives the synchronous belt 82 to move, the movement of the synchronous belt 82 drives the gear 1 81 to rotate, the gear 1 81 drives the rotating shaft 1 7 and the rotating shaft 2 71 to rotate respectively, thereby driving the baffle 1 72 and the filter screen 73 on the rotating shaft 1 7 and the baffle 2 74 on the rotating shaft 2 71 to move along the circumference, and the baffle 2 74 can be fixed by the magnetic block 87, and then the slide bar 3 continues to move. Since the fixed rod 86 no longer moves, the shift rod 84 is forced to rotate downward, and the torsion spring 85 twists. When the fixed rod 86 no longer contacts the shift rod 84, the torsion spring 85 drives the shift rod 84 to rotate and reset.

[0048] Combined with attachment Figure 3 , Attachment Figure 9 , Attachment Figure 10 , Attachment Figure 11 , Attachment Figure 12 As shown, the charging pile 1 is provided with a cleaning mechanism 9 for cleaning the surface of the filter 73. The cleaning mechanism 9 includes a brush 91 slidably arranged on the filter 73. The charging pile 1 is provided with a shielding plate 910 above the air inlet 5. A driving rod 93 is slidably arranged on the shielding plate 910. The filter 73 moves in a circle along the rotating shaft 7 and then engages with the driving rod 93. The movement of the driving rod 93 drives the brush 91 to move on the filter 73.

[0049] The brush 91 is provided with a clamping plate 94 , the clamping plate 94 is provided with an arc block 95 , the driving rod 93 is provided with an arc groove 96 that cooperates with the arc block 95 , and a synchronization rod 97 is provided between adjacent driving rods 93 .

[0050] The working principle of the cleaning mechanism 9 is as follows: when the charging pile 1 is not in use and the filter 73 needs to be cleaned, since the brush 91 is slidably set on the filter 73, and the filter 73 is rotatable, in order to ensure that the brush 91 can be driven by the driving rod 93 after rotation, an arc block 95 and an arc groove 96 are provided. After the filter 73 rotates, the arc block 95 thereon enters the arc 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 73. Specifically, when the charging pile 1 is not in use, the filter 73 is in a horizontal state and the arc block 95 on the clamping plate 94 is located in the arc groove 96. Then the synchronization rod 97 is pulled, and the synchronization 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 73. At this time, the dust is swept off, and then the synchronization rod 97 is pushed to reset the brush 91.

[0051] Combined with attachment Figure 3 , Attachment Figure 9 , Attachment Figure 10 As shown, a buffer block 99 is slidably provided in the slide groove 41 and a spring is provided between the buffer block 99 and the bottom surface of the slide groove 41. A rack 1 911 is provided on the buffer block 99. A gear 2 912 is rotatably provided on the charging pile 1 and meshes with the rack 1 911. An L-shaped rod 98 is slidably provided on the charging pile 1. A connecting plate 92 is provided between two adjacent baffles 1 72. One end of the L-shaped rod 98 is fixedly connected to one of the baffles 1 72, and the other end of the L-shaped rod 98 is provided with a rack 2 913 meshing with the gear 2 912.

[0052] The baffle 1 72 is specifically shaped as a vertical Z-shaped plate;

[0053] A connecting column is provided under the slide rod 3, and a counterweight block is provided on the connecting column.

[0054] Working principle: In order to prevent the slide bar 3 from moving down too quickly and hitting the inner wall of the slide groove 41, a buffer block 99 and a spring are set in the slide groove 41, so as to reduce the falling speed of the slide bar 3. Since the baffle 1 72 needs to move up when the buffer block 99 moves down, in order to move the baffle 1 72 up, a rack 1 911, a gear 2 912 and a rack 2 913 are set. When the rack 1 911 moves down, the ventilation gear 2 912 is driven, and the rack 2 913 moves upward. Since the filter 73 needs to rotate first, the setting position of the fixed rod 86 should be located above the buffer block 99. Specifically, when charging is needed, the slide bar 3 moves up, the spring pushes the buffer block 99 to move up, and the buffer block 99 drives the rack 1 911 moves up, rack 1 911 drives gear 2 912 to rotate, gear 2 912 drives rack 2 913 to move down, rack 2 913 drives connecting plate 92 to move down, connecting plate 92 drives baffle 1 72 to move down, baffle 1 72 no longer blocks the air inlet 5, then the slide bar 3 drives the rotating mechanism 8, the rotating mechanism 8 drives the filter 73 to rotate, so that the filter 73 is located in the air inlet 5. When not charging, the slide bar 3 first drives the rotating mechanism 8 so that the filter 73 is no longer located in the air inlet 5, and then drives the buffer block 99 to move down, and the buffer block 99 drives baffle 1 72 to move up through rack 1 911, gear 2 912 and rack 2 913 to block the air inlet 5;

[0055] Since a portion of the filter 73 will be located inside the air inlet 5 when the filter 73 is in a horizontal state, in order to ensure that the baffle 1 72 completely blocks the air inlet 5, the baffle 1 72 is configured as a Z-shaped plate, with one end of the baffle 1 72 abutting against the end of the filter 73.

[0056] In actual use, it is necessary to first pull the charging cable 11 so that it changes from a perpendicular state to a certain angle with the ground, so that the control mechanism 27 can release the fixation of the guide roller 21, and then pull the charging cable 11 while maintaining the angle so that the charging cable 11 is close to the car charging slot, and then continue to pull the charging cable 11 to change the angle of the charging cable 11 with the ground, so that the control mechanism 27 fixes the guide roller 21. After charging is completed, unplug the charging head 12 and release it. The cleaning mechanism 9 can be used regularly to clean the surface of the filter 73.

[0057] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
