Description

Technical Field

[0001] The present invention relates to a new energy vehicle charging technology, in particular to an embedded lifting type charging pile for new energy vehicles and a charging method. Background Art

[0002] New energy vehicles refer to vehicles that use non-traditional fuels as a power source, mainly including electric vehicles, plug-in hybrid vehicles, fuel cell vehicles, etc. Compared with traditional internal combustion engine vehicles that rely on oil, the core advantage of new energy vehicles lies in reducing dependence on fossil fuels, reducing environmental pollution, and promoting sustainable development. Unlike traditional internal combustion engine vehicles, which generate power by burning gasoline or diesel, new energy vehicles are powered by electrical energy stored in batteries. Therefore, new energy vehicles need to be charged regularly to replenish the electrical energy in the battery to ensure that the vehicle can continue to operate normally. Charging piles for new energy vehicles are devices specifically used to provide electrical energy replenishment for electric vehicles. They help charge the vehicle by transmitting electricity from the power grid to the battery of the electric vehicle to ensure its normal operation.

[0003] At present, charging piles for new energy vehicles have charging facilities with lifting functions on the market in order to improve the convenience of use and space utilization efficiency of charging piles. Such charging piles are generally designed to be embedded in the ground or on the ground, and exposed to the ground or hidden underground as needed through a lifting mechanism. When the charging pile is needed, the charging pile can be automatically or manually lifted for charging; when not in use, it will be lowered underground or hidden under the ground, thereby saving space and avoiding obstruction of traffic or affecting the appearance; however, when the embedded lifting type charging pile for new energy vehicles is in use, in order to realize the lifting function of the charging pile, the charging gun is usually designed to be embedded inside the charging pile. The purpose of this design is to ensure that the charging gun does not interfere with the lifting process when the charging pile is raised. However, in actual use, when the charging gun needs to be pulled out, the charging gun is still fixed inside the charging pile. This structure makes it inconvenient to remove the charging gun, especially after the charging pile has been raised. The operator needs to use force to remove the charging gun from the charging pile. This process is not only cumbersome, but also causes inconvenience in operation, which in turn affects the use experience and efficiency of the charging pile. Summary of the invention

[0027] The two first conductive rollers, the two second conductive rollers and the third conductive roller are housed in the body of the pile body for W-shaped conduction of the cable.

[0028] The above-mentioned built-in lifting type charging pile for new energy vehicles: a slot for the charging gun to be extended and retracted is provided on one side of the pile body, a blocking plate is provided at the slot correspondingly, a rotating rod is fixedly connected to one end of the bottom of the blocking plate, and the rotating rod is rotatably connected to the pile body;

[0029] The rotating rod is provided with a slotted hole, and the slotted hole limits the rotating rod to rotate back and forth 90 degrees on the pile body.

[0030] The charging method using the above-mentioned built-in lifting type new energy vehicle charging pile includes the following steps:

[0031] Step 1: Scan the QR code on the top of the pile body. After the code is scanned and activated, the upper device starts the motor, and the motor drives the first screw rod to rotate, so that the pile body rises in the embedding chamber;

[0032] Step 2: When the pile body is raised to halfway, the side of the blocking plate loses its contact with the side wall of the embedded bin, and the blocking plate is rotated 90 degrees on one side of the pile body through the rotating rod to unfold. At this time, the first screw rod continues to rotate to make the pile body continue to rise, and the second screw rod will continue to lift up inside the first screw rod, and continue to drive the sleeve block to rise after the prismatic block abuts against the sleeve block;

[0033] Step 3: During the rising process of the sleeve block, the linkage drives the sliding frame to slide on the mounting frame toward the blocking plate, thereby driving the two transmission shafts to rotate synchronously, so that the lifting frame rises to below the sliding frame;

[0034] Step 4: At this time, the charging gun is exposed outside the pile body, and the cable is in a relaxed state and curled up inside the pile body. When pulling out the charging gun, the cable can be easily pulled out of the pile body to charge the new energy vehicle;

[0035] Step 5: After the charging gun is used, the upper device controls the overall reset, so that the charging gun and the cable are stored in the pile body, and the pile body is lowered and stored in the embedded bin.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] By reasonably designing the structural composition and connection relationship of the driving structure and the linkage storage structure, in the process of the pile body rising to the outside of the embedded bin, when the pile body rises to half of the predetermined height, the driving structure will cooperate with the linkage storage structure to push the charging gun out from the inside of the pile body. As the pile body further rises until it reaches the highest position, the charging gun is completely exposed on the outside of the pile body, and the cable is adjusted from a taut state to a relaxed state to facilitate the user to take and place the charging gun, thereby improving the user experience.

[0038] Specifically, the transmission mechanism is driven by the motor. When the pile body is raised to half of the predetermined height, the transmission mechanism will contact the linkage mechanism and drive the linkage mechanism to move up and down. When the linkage mechanism moves, it will drive the telescopic mechanism to move. The telescopic mechanism can control the telescopic state of the charging gun inside the pile body. When the telescopic mechanism moves, it will also drive the storage mechanism to operate. The storage mechanism is used to control the tightness of the cable. When the charging gun is extended outside the pile body, the cable is in a relaxed state on the storage mechanism. At this time, the user can easily extend the cable from the pile body by taking the charging gun.

[0039] After the charging gun is used, it is placed in place, and then the components are reset and moved. The telescopic mechanism carries the charging gun and is stored inside the pile body. When the telescopic mechanism is reset and moved, the storage mechanism will tighten the cable so that the stretched cable is stored inside the pile body again. When the pile body is lowered to the point where the blocking plate contacts the top of the embedding bin, the blocking plate will block the slot on the pile body. By providing a blocking plate at the slot of the pile body, when the charging pile is embedded underground and not in use, it can effectively prevent the missing slot on the pile body from entering humid gas, thereby improving the sealing effect inside the pile body.

DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0055] See also Figure 1 to Figure 3 In an embodiment of the present invention, an embedded lifting type charging pile for new energy vehicles comprises an embedded warehouse 1 installed on the ground, a pile body 2 arranged on the embedded warehouse 1, a cable 33 connected to the pile body 2, and a charging gun 32 connected to the cable 33. A driving structure is arranged in the cavity of the embedded warehouse 1, a linkage storage structure is arranged in the cavity of the pile body 2, the driving structure is connected to the linkage storage structure, and the linkage storage structure is connected to the charging gun 32 and the cable 33.

[0056] The driving structure includes a motor 5 installed in the cavity of the embedded bin 1 and a transmission mechanism arranged on the output end of the motor 5, and the transmission mechanism is connected to the linkage storage structure;

[0057] The linkage storage structure includes a telescopic mechanism connected to the charging gun 32, a storage mechanism connected to the cable 33 and linked to the telescopic mechanism, and a linkage mechanism for connecting the telescopic mechanism and the transmission mechanism;

[0058] When the motor 5 is working, it is used to drive the transmission mechanism to operate. When the transmission mechanism operates, it is used to drive the pile body 2 to move up and down on the embedded warehouse 1. When the pile body 2 moves up and down, the transmission mechanism drives the linkage mechanism to operate. The operation of the linkage mechanism drives the storage mechanism and the telescopic mechanism to operate. When the storage mechanism operates, it controls the tightness of the cable 33. When the telescopic mechanism operates, it controls the telescopic state of the charging gun 32 on the embedded warehouse 1.

[0059] In this embodiment, when the motor 5 is actuated, the transmission mechanism can be actuated, so that the pile body 2 can be raised and lowered in the cavity of the embedding bin 1. After the QR code on the top of the pile body 2 is scanned and activated, the motor 5 is controlled by the upper device to start, and the transmission mechanism can make the pile body 2 rise in the cavity of the embedding bin 1. When the pile body 2 rises to half the height, the transmission mechanism will abut against the linkage mechanism, so that the linkage mechanism will be actuated. When the linkage mechanism is actuated, the telescopic mechanism will be telescopically adjusted in the cavity of the pile body 2. When the pile body 2 is raised, the telescopic mechanism will move the charging gun 32 Extending out of the pile body 2, as the pile body 2 gradually rises, the charging gun 32 will gradually extend out of the pile body 2. When the pile body 2 is raised to the highest position, the charging gun 32 is completely exposed outside the pile body 2, and when the telescopic structure moves, the storage mechanism will be linked to operate. The storage mechanism is used to control the tension of the cable 33 in the pile body 2. When the charging gun 32 is extended outside the pile body 2, the cable 33 on the storage mechanism is in a relaxed state. By pulling the charging gun 32, the cable 33 can be pulled out of the pile body 2 to meet the charging needs.

[0060] See also Figure 4 , Figure 6 As a further solution of the present invention, an embedding hole 3 is provided at the bottom of the pile body 2, and a prismatic sliding groove 4 is provided on the pile body 2 at the location of the embedding hole 3.

[0061] The transmission mechanism comprises a first screw rod 6 coaxially fixed to the output shaft of the motor 5, a connecting plate 8 threadedly connected to the first screw rod 6, and a second screw rod 9 threadedly connected to the center of the first screw rod 6;

[0062] Two guide posts 7 are fixedly connected to both sides of the motor 5. The two guide posts 7 and the first screw rod 6 are arranged in an equilateral triangle. The two guide posts 7 are slidably inserted into the corresponding guide holes at the bottom of the pile body 2. The connecting plate 8 is fixedly connected to the embedding hole 3.

[0063] The thread directions of the first screw rod 6 and the second screw rod 9 are opposite. A prismatic block 10 is fixedly connected to the top of the second screw rod 9. A limiting groove 11 is provided on one side of the prismatic block 10. The prismatic block 10 is slidably connected to a prismatic sliding groove 4 provided on the pile body 2.

[0064] In this embodiment, since the thread directions of the first screw rod 6 and the second screw rod 9 are opposite, and the first screw rod 6 is threadedly connected to the connecting plate 8, the connecting plate 8 is fixedly connected to the embedding hole 3 at the bottom of the pile body 2, and the prismatic block 10 arranged on the top of the second screw rod 9 is slidably connected in the prismatic slide groove 4. Due to the restriction of the prismatic block 10, the second screw rod 9 can only be vertically lifted and lowered in the prismatic slide groove 4 and cannot rotate on its own. The second screw rod 9 is threadedly connected to the inside of the first screw rod 6. When the first screw rod 6 rotates to raise the pile body 2, the second screw rod 9 will rise inside the pile body 2, thereby satisfying the driving use of the linkage mechanism and ensuring the use effect. When the first screw rod 6 reverses to lower the pile body 2, the second screw rod 9 will move downward inside the first screw rod 6 to achieve a linkage driving effect.

[0065] See also Figure 8 , Fig. 9 As a further solution of the present invention, the linkage mechanism includes a sleeve block 12 slidably connected in the cavity of the pile body 2, a connection frame 13 fixedly connected to the sleeve block 12, a first gear 15 connected to the connection frame 13, and a connection assembly arranged inside the sleeve block 12;

[0066] The sleeve block 12 is provided with a slot hole matched with the prismatic block 10, and a first rack 14 is provided on one side of the inner wall of the connecting frame 13, and the first rack 14 is meshed with the first gear 15, and an arc-shaped protrusion is provided on one side of the first gear 15, and a first transmission wheel 16 is fixedly connected to the other side of the first gear 15;

[0067] A rotating shaft 17 is fixedly connected to the center of the first transmission wheel 16 . The rotating shaft 17 is rotatably connected to the cavity of the pile body 2 . A belt 25 is transmission-connected to the first transmission wheel 16 .

[0068] The connecting assembly includes a resisting block 18, two connecting frames 20 connected to the resisting block 18, and a limiting block 22 connected to the two connecting frames 20. The two connecting frames 20 are fixedly connected by a central shaft 21, and the central shaft 21 is rotatably connected to the sleeve block 12.

[0069] The abutment block 18 and the limit block 22 are respectively slidably connected to the corresponding slots on the sleeve block 12, and the first sliding roller 19 and the second sliding roller 23 are respectively fixedly connected to the two sides of the abutment block 18 and the limit block 22, and the connecting frame 20 is provided with a plurality of sliding grooves for realizing sliding connection in correspondence with the first sliding roller 19 and the second sliding roller 23;

[0070] Two springs 24 are symmetrically abutted on one side of the limit block 22 , and the other end of the spring 24 abuts on the sleeve block 12 . The limit block 22 is correspondingly engaged with the limit groove 11 , and the abutment block 18 abuts against the arc-shaped protrusion provided on the first gear 15 .

[0071] In this embodiment, the prismatic block 10 will continue to rise under the lifting of the second screw rod 9. Before the prismatic block 10 abuts against the sleeve block 12, the sleeve block 12 is in the lowest position. At this time, the abutment block 18 on the sleeve block 12 abuts against the arc-shaped protrusion provided on the first gear 15, so that the abutment block 18 slides and contracts toward the inside of the sleeve block 12, and with the cooperation of the first sliding roller 19, the connecting frame 20, the central axis 21 and the second sliding rod 23, the limiting block 22 slides toward the side of the abutment block 18, so that the spring 24 is compressed; when the prismatic block 10 abuts against the sleeve block 12, the prismatic block 10 drives the sleeve block 12 and the connecting frame 20 to move upward. When the frame 13 rises, the abutment block 18 loses its abutment with the arc-shaped protrusion provided on the first gear 15 and slides toward the outside of the sleeve block 12. At this time, the spring 24 which was originally in a contracted state rebounds, so that the limit block 22 slides to the side away from the abutment block 18 and is plugged and engaged with the limit groove 11 provided on the prismatic block 10. When the prismatic block 10 drives the sleeve block 12 and the connecting frame 13 to continue to rise, the first gear 15 rotates under the meshing action of the first gear 15 and the first rack 14 on the inner wall of the connecting frame 13, so that the first transmission wheel 16 fixedly connected thereto rotates synchronously, and then the belt 25 is driven.

[0072] When the prismatic block 10 descends, due to the snap-fit ​​connection between the limit groove 11 and the limit block 22, the sleeve block 12 will descend synchronously with the prismatic block 10. When the abutment block 18 abuts against the arc-shaped protrusion on one side of the first gear 15 again, the limit block 22 will be disengaged from the snap-fit ​​connection with the limit groove 11. At this time, the prismatic block 10 will be disengaged from the abutment with the sleeve block 12. When the prismatic block 10 continues to descend, the sleeve block 12 is in the lowest position and does not move, meeting the requirements of linkage use.

[0073] See also Fig.10 As a further solution of the present invention, the telescopic mechanism includes a mounting frame 28 mounted on the embedded bin 1, a sliding frame 29 slidably connected to the mounting frame 28, and a driving shaft 27 rotatably connected to the center bottom of the mounting frame 28;

[0074] One end of the driving shaft 27 is fixedly connected to a second transmission wheel 26, and the second transmission wheel 26 is in transmission connection with the belt 25. Second racks 30 are provided at the bottom of both sides of the sliding frame 29;

[0075] A socket 31 is fixedly connected to the center of the sliding frame 29, and the socket 31 is correspondingly plugged into the charging gun 32. A connecting block is fixedly connected to the bottom of the socket 31. A threaded groove is provided on the driving shaft 27, and the connecting block is threadedly slidably connected to the threaded groove.

[0076] In this embodiment, when the belt drives the second transmission wheel 26 to rotate, the drive shaft 27, one end of which is fixedly connected to the second transmission wheel 26, will rotate synchronously. At this time, since the drive shaft 27 is threadedly connected to the connection block at the bottom of the socket 31, the socket 31 is fixedly connected to the sliding frame 29, and the sliding frame 29 is slidably connected to the mounting frame 28, when the drive shaft 27 rotates, the socket 31 will move on the drive shaft 27, thereby driving the sliding frame 29 to slide on the mounting frame 28; and since the socket 31 is plugged with the charging gun 32, when the socket 31 moves on the drive shaft 27, it can control the telescopic adjustment of the charging gun 32 in the pile body 2. It can be seen that the telescopic mechanism can control the telescopic state of the charging gun 32, so that the charging gun 32 can be extended out of the body of the pile body 2 after the pile body 2 is raised and in place, so as to facilitate the charging gun 32 to be taken out.

[0077] See also Fig.11 , Fig.12 As a further solution of the present invention, the storage mechanism includes two transmission shafts 35 symmetrically connected to the pile body 2, a lifting frame 36 connected to the two transmission shafts 35 on both sides, and two second bevel gears 38 respectively arranged on the top of the two transmission shafts 35;

[0078] A first bevel gear 37 is fixedly connected to the top of the transmission shaft 35, and the first bevel gear 37 is meshed with the second bevel gear 38. A second gear 39 is fixedly connected to the center of the second bevel gear 38 away from the transmission shaft 35, and the second gear 39 is meshed with the second rack 30. The second gear 39 is rotatably connected in the cavity of the pile body 2.

[0079] The transmission shaft 35 is provided with a spiral groove, and the lifting frame 36 is provided with a semicircular protrusion slidably connected to the spiral groove.

[0080] A third conduction roller 3403 is rotatably connected to the pile body 2 between the tops of the two transmission shafts 35, two first conduction rollers 3401 are vertically symmetrically rotatably connected to the pile body 2 on one side of the third conduction roller 3403, and two second conduction rollers 3402 are symmetrically rotatably connected to the lifting frame 36;

[0081] The two first conducting rollers 3401 , the two second conducting rollers 3402 and the third conducting roller 3403 are housed in the pile body 2 to conduct the cable 33 in a W-shape.

[0082] In this embodiment, since the second gear 39 is meshed with the second racks 30 provided at the bottom of both sides of the sliding frame 29, the second gear 39 can be rotated when the sliding frame 29 moves; and the second gear 39 is fixedly connected with the second bevel gear 38 coaxially, and the first bevel gear 37 is meshed with the second bevel gear 38, so the rotation of the second gear 39 will drive the second bevel gear 38 to rotate synchronously, thereby driving the first bevel gear 37 to rotate, thereby driving the transmission shaft 35 fixedly connected with the first bevel gear 37 to rotate synchronously; and the transmission shaft 35 is provided with a spiral groove, and the inner wall of the connection between the two sides of the lifting frame 36 and the transmission shaft 35 is provided with a semicircular protrusion, and the semicircular protrusion abuts against the spiral groove, so when the transmission shaft 35 rotates, the lifting frame 36 can be driven to move up and down on the transmission shaft 35. Therefore, when the sliding frame 29 moves from one side to the other side on the mounting frame 28, the transmission shaft 35 can be driven to rotate through this design, thereby driving the lifting frame 36 to move up and down on the transmission shaft 35 by a stroke. It can be seen that when the charging gun 32 extends out of the pile body 2, the lifting frame 36 moves up a stroke on the transmission shaft 35 to one end close to the second bevel gear 38. At this time, with the cooperation of the lifting frame 36 and the two first conduction rollers 3401, the two second conduction rollers 3402 and the third conduction roller 3403, the cable 33 that was originally in a taut state can be adjusted to a relaxed state, so that when the charging gun 32 is taken out, the cable 33 can be pulled toward the outside of the pile body 2; and when the charging gun 32 is retracted into the body of the pile body 2, the lifting frame 36 moves down a stroke on the transmission shaft 35 to the bottom of the transmission shaft 35. At this time, with the cooperation of the lifting frame 36 and the two first conduction rollers 3401, the two second conduction rollers 3402 and the third conduction roller 3403, the cable 33 can be stored in a W shape, so that the cable 33 that was originally pulled out of the outside of the pile body 2 is stored into the body of the pile body 2, and the automatic storage of the cable 33 when the pile body 2 descends is realized. Through the coordinated design of the telescopic mechanism and the storage mechanism, the charging gun 32 and the cable 33 can be stored inside the pile body 2 when the pile body 2 descends, and will not block the descending stroke of the pile body 2 on the embedding chamber 1.

[0083] See also Fig.13 As a further solution of the present invention, a slot for the charging gun 32 to be extended and retracted is provided on one side of the pile body 2, a blocking plate 40 is provided corresponding to the slot, a rotating rod 41 is fixedly connected to one end of the bottom of the blocking plate 40, and the rotating rod 41 is rotatably connected to the pile body 2;

[0084] The rotating rod 41 is provided with a slotted hole, and the slotted hole limits the rotating rod 41 to rotate back and forth 90 degrees on the pile body 2 .

[0085] In this embodiment, when the pile body 2 is raised to halfway, the side of the blocking plate 40 loses contact with the inner wall of the embedding chamber 1. When the telescopic mechanism is in operation, the blocking plate 40 can be pushed out, so that the blocking plate 40 is deployed on the pile body 2 through a 90-degree rotation of the rotating rod 41. The slots provided on the rotating rod 41 can limit the 90-degree reciprocating rotation of the rotating rod 41. When the pile body 2 is lowered, the blocking plate 40 will contact the top of the embedding chamber 1, thereby forcing the blocking plate 40 to block the missing groove of the pile body 2. Through this design, the missing groove on the pile body 2 can be blocked, and when the pile body 2 is embedded in the ground and not in use, the missing groove on the pile body 2 is prevented from entering humid gas, thereby improving the sealing effect inside the pile body 2.

[0086] The charging method using the above-mentioned built-in lifting type new energy vehicle charging pile includes the following steps:

[0087] Step 1: Scan the QR code on the top of the pile body 2. After the code is scanned and activated, the upper device starts the motor 5, and the motor 5 drives the first screw 6 to rotate, so that the pile body 2 rises in the embedding chamber 1;

[0088] Step 2: When the pile body 2 is halfway raised, the side of the blocking plate 40 loses contact with the side wall of the embedding chamber 1, and the blocking plate 40 is rotated 90 degrees on one side of the pile body 2 by the rotating rod 41. At this time, the first screw rod 6 continues to rotate to make the pile body 2 continue to rise, and the second screw rod 9 will continue to rise inside the first screw rod 6, and after the prismatic block 10 abuts against the sleeve block 12, it continues to drive the sleeve block 12 to rise;

[0089] Step 3: During the rising process of the sleeve block 12, the linkage drives the sliding frame 29 to slide on the mounting frame 28 toward the blocking plate 40, thereby driving the two transmission shafts 35 to rotate synchronously, so that the lifting frame 36 rises to the bottom of the sliding frame 29;

[0090] Step 4: At this time, the charging gun 32 is exposed outside the pile body 2, and the cable 33 is in a relaxed state and curled up inside the pile body 2. When the charging gun 32 is pulled out, the cable 33 can be easily pulled out from the pile body 2 to charge the new energy vehicle;

[0091] Step 5: After the charging gun 32 is used, the upper device controls the overall reset, so that the charging gun 32 and the cable 33 are retracted into the pile body 2, and the pile body 2 is lowered and retracted into the body of the embedding bin 1.

[0092] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
