[0003] Chinese patent CN107745652B discloses a wall-mounted car charging pile for a parking shed, comprising a charging pile body, which is arranged on the upper end of a hollow cylindrical support column of the parking shed through a detachable fixing device. A cable device is provided inside the hollow cylindrical support column. The detachable fixing device is composed of a fixing circular hole, an arc-shaped fixing ring, a circular boss, a locking block, a threaded through hole, a locking screw, a locking nut, a rectangular groove and an inverted L-shaped hook. The cable device is composed of a fixed bearing, a fixed rotating shaft, a cross-shaped bracket, a hollow cylindrical fixing frame, a torsion spring, a charging cable, a power supply plug and a vehicle plug.

[0014] Preferably, the charging connection line passes through the position-limiting fixed housing and passes between the two position-limiting rotating wheels, and the position-limiting rotating wheels are slidably mounted inside the position-limiting fixed housing through the position-limiting movable housing;

[0022] A control method based on a wall-mounted charging pile uses the above-mentioned charging pile.

[0023] Compared with the prior art, the present invention provides a charging pile and a control method based on a wall-mounted charging pile, which has the following beneficial effects:

[0024] 1. This type of charging pile controls the bending state of the charging cable by the position of the cable limit rod, which can straighten and extend the charging cable inside the charging pile body during charging to facilitate charging of the car. After charging is completed, the cable limit rod bends the excess charging cable and stores it inside the charging pile body to prevent the excess charging cable from sagging to the ground and rubbing against the ground and being stepped on, affecting its service life.

[0025] 2. This type of charging pile limits the position of the charging cable by using two limit wheels. After the limit wheel clamps the charging cable, the movement of the charging cable can drive the limit wheel to rotate, and the rotation direction of the limit wheel is limited by the engagement between the limit ratchet and the ratchet block, so that the charging cable can only move from the inside of the charging pile body to the outside of the charging pile body, thereby preventing the cable recovery mechanism from tightening the charging cable during charging and causing damage to the charging gun.

[0026] 3. This type of charging pile limits the position of the connection between the first connecting rod and the second connecting rod by a limiting block and a limiting connecting spring, thereby controlling the angle between the first connecting rod and the second connecting rod. When the angle between the first connecting rod and the second connecting rod changes, the distance between the two limiting movable shells also changes accordingly, thereby being able to control the clamping and release state of the limiting wheel on the charging connection line.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a charging pile and a control method based on a wall-mounted charging pile.

[0040] Example 1

[0041] See also Figure 1 - Figure 10 A charging pile includes a charging pile body 1, a charging connection line 2 is connected to the interior of the charging pile body 1, the other end of the charging connection line 2 is connected to a charging gun 3, a cable recovery mechanism 4 is installed inside the charging pile body 1, a cable limiting mechanism 5 is installed inside the charging pile body 1, a transmission control mechanism 6 is installed outside the cable limiting mechanism 5, and a mounting partition plate 7 is installed inside the charging pile body 1;

[0042] One end of the charging cable 2 is connected to the inside of the charging pile body 1, and the other end of the charging cable 2 passes through the cable recovery mechanism 4 and the cable restriction mechanism 5 to connect to the charging gun 3. The charging gun 3 can be inserted into the side of the charging pile body 1;

[0043] The cable recovery mechanism 4 can bend and fold the charging connection cable 2 inside the charging pile body 1 layer by layer. The cable limiting mechanism 5 can clamp the charging connection cable 2 and limit the moving direction of the charging connection cable 2. When the end of the charging connection cable 2 connected to the charging gun 3 moves outward, the cable recovery mechanism 4 can be driven to move by the part connected to the cable recovery mechanism 4. After the cable recovery mechanism 4 moves, the charging connection cable 2 can be straightened inside the charging pile body 1. When the charging gun 3 is inserted into the side of the charging pile body 1, the cable limiting mechanism 5 can be driven to loosen the clamping of the charging connection cable 2 through the transmission control mechanism 6.

[0044] When charging the car, first remove the charging gun 3 from the charging pile body 1. At this time, the transmission control mechanism 6 can drive the cable limiting mechanism 5 to clamp the charging connection line 2. After clamping the charging connection line 2, the cable limiting mechanism 5 can make the charging connection line 2 only able to move from the inside of the charging pile body 1 to the outside of the charging pile body 1. At this time, when the charging gun 3 is moved and the charging gun 3 is plugged into the car, the charging connection line 2 inside the charging pile body 1 can be gradually straightened and moved to the outside of the charging pile body 1. When the charging connection line 2 inside the charging pile body 1 moves toward the outside of the charging pile body 1, the cable recovery mechanism 4 can be pulled, and the charging connection line 2 outside the charging pile body 1 moves toward the inside of the charging pile body 1 and is locked by the cable limiting mechanism 5, so that the charging connection line 2 and the cable recovery mechanism 4 cannot continue to move. After charging is completed After completion, the charging gun 3 is inserted back into the charging pile body 1. When the charging gun 3 is inserted back into the charging pile body 1, the transmission control mechanism 6 can drive the cable limiting mechanism 5 to move and release the clamping of the charging connection line 2. After the cable limiting mechanism 5 releases the restriction on the charging connection line 2, the cable recovery mechanism 4 rebounds and drives the charging connection line 2 outside the charging pile body 1 to move toward the inside of the charging pile body 1. Driven by the cable recovery mechanism 4, the charging connection line 2 inside the charging pile body 1 becomes a layer-by-layer bent and folded state. The charging connection line 2 is stretched by pulling it during charging to adapt to the distance between the charging pile and the car. After charging, the charging connection line 2 is driven by the cable recovery mechanism 4 to be retracted into the inside of the charging pile body 1, thereby preventing the charging connection line 2 from rubbing against the ground and being stepped on, affecting its service life.

[0045] Example 2

[0046] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10The cable recovery mechanism 4 includes a recovery chute 41. A plurality of recovery chutes 41 are provided inside the charging pile body 1. A recovery slider 43 is slidably installed inside the plurality of recovery chutes 41. The outside of the recovery slider 43 is connected to a recovery spring 42. A sliding baffle 44 is installed on the top of the recovery slider 43. A cable limiting rod 46 is connected to the top of the sliding baffle 44. A baffle chute 45 is installed above the recovery chute 41. The sliding baffle 44 is slidably installed inside the baffle chute 45.

[0047] Multiple recovery chutes 41 are evenly spaced inside the charging pile body 1. The structures inside two adjacent recovery chutes 41 are opposite. The outside of the recovery slider 43 is connected to the inside of the recovery chute 41 through the recovery spring 42.

[0048] When the recovery slider 43 moves inside the recovery chute 41 , it can drive the sliding baffle 44 to move into the baffle chute 45 . When the sliding baffle 44 moves into the baffle chute 45 , it can drive the cable limiting rod 46 to move synchronously.

[0049] The charging cable 2 passes around all the cable limit rods 46 in turn in sequence, and the charging cable 2 is arranged in a circle around the cable limit rod 46. When the charging cable 2 is stretched outward, it can drive the cable limit rod 46 to move toward the middle of the recovery chute 41. When the cable limit rod 46 moves toward the middle of the recovery chute 41, it can drive the recovery slider 43 to move toward the middle of the recovery chute 41 and compress the recovery spring 42. When the charging cable 2 is in a relaxed state, the recovery spring 42 rebounds and drives the cable limit rod 46 to move to both sides of the recovery chute 41.

[0050] In the normal storage state, the cable limiting rods 46 are staggered on both sides of the recovery chute 41, and the charging connection line 2 passes around all the cable limiting rods 46 in sequence. When the charging connection line 2 inside the charging pile body 1 moves toward the outside of the charging pile body 1, the charging connection line 2 inside the charging pile body 1 first gradually straightens from the bent state. When the charging connection line 2 is straightened, it can drive the cable limiting rods 46 to move from both sides of the recovery chute 41 to the middle of the recovery chute 41. During the movement of the cable limiting rods 46, the recovery slider 43 can be driven to move synchronously, and the sliding baffle 44 can be driven to slide toward the inside of the baffle chute 45. During the movement of the recovery slider 43 toward the middle of the recovery chute 41, the recovery spring 42 can be contracted. During the charging process, the cable limiting mechanism 5 can limit the charging connection line 2 to prevent the charging connection line 2 outside the charging pile body 1 from entering the inside of the charging pile body 1, so that the recovery spring 42 cannot rebound during charging. After charging is completed, the cable limiting mechanism 5 releases the restriction on the charging connection line 2. At this time, the recovery spring 42 rebounds and drives the recovery slider 43 to move to both sides of the recovery chute 41. During the movement of the recovery slider 43, the cable limiting rod 46 can drive the cable limiting rod 46 to move to both sides of the recovery chute 41, and during the movement of the cable limiting rod 46, the charging connection line 2 can be pulled to collect the charging connection line 2 outside the charging pile body 1 into the inside of the charging pile body 1. In the process of the cable limiting rod 46 pulling the charging connection line 2, the charging connection line 2 can also be restored to a bent state. The bending state of the charging connection line 2 is controlled by the position of the cable limiting rod 46. The charging connection line 2 can be extended during charging to facilitate charging of the car. After charging is completed, the cable limiting rod 46 bends the excess charging connection line 2 and stores it inside the charging pile body 1 to prevent the excess charging connection line 2 from sagging to the ground and rubbing against the ground and being stepped on, affecting its service life.

[0051] Example 3

[0052] The difference from the above embodiment is that, please refer to Figure 1 - Figure 10 The cable limiting mechanism 5 includes a fixed limiting shell 51, which is fixedly installed inside the charging pile body 1. Two movable limiting shells 52 are slidably installed inside the fixed limiting shell 51. A limiting shaft 53 is fixedly installed inside the two movable limiting shells 52. A limiting wheel 54 is rotatably installed outside the limiting shaft 53. The bottom of the limiting wheel 54 is connected to a limiting ratchet 55. A ratchet block 56 is installed at the bottom of the movable limiting shell 52.

[0053] The charging cable 2 passes through the position-limiting fixed housing 51 and passes between the two position-limiting rotating wheels 54 . The position-limiting rotating wheels 54 are slidably mounted inside the position-limiting fixed housing 51 through the position-limiting movable housing 52 .

[0054] When the two limiting wheels 54 clamp the charging connection cable 2, the charging connection cable 2 can drive the limiting wheels 54 to rotate when the charging connection cable 2 moves. When the limiting wheels 54 are not in contact with the charging connection cable 2, the charging connection cable 2 is in a relaxed state.

[0055] The limiting ratchet 55 is rotatably mounted on the outside of the limiting rotating shaft 53 via the limiting rotating wheel 54. The outsides of the two limiting ratchets 55 are both engaged with the ratchet block 56. The two limiting ratchets 55 rotate in opposite directions.

[0056] When the limiting ratchet 55 is engaged with the ratchet block 56 , the rotation direction of the limiting wheel 54 connected to the limiting ratchet 55 can be limited. When the rotation direction of the limiting wheel 54 is limited, the moving direction of the charging connection cable 2 can be limited.

[0057] The transmission control mechanism 6 includes a first connecting rod 61 and a second connecting rod 62, which are respectively installed on the top of the two limit movable shells 52. The first connecting rod 61 and the second connecting rod 62 are rotatably connected by a connecting shaft 63. The outside of the connecting shaft 63 is connected to a limit connecting spring 64. The top of the connecting shaft 63 is connected to a shaft connecting rod 65. The outside of the shaft connecting rod 65 is connected to a transmission connecting rod 66. A limit sliding groove 68 is provided inside the side wall of the charging pile body 1, and a limit block 67 is slidably installed inside the limit sliding groove 68.

[0058] The top of the rotating shaft connecting rod 65 passes through the mounting partition plate 7 and is connected to the transmission connecting rod 66. The rotating shaft connecting rod 65 and the limit block 67 are connected through the transmission connecting rod 66. When the charging gun 3 is inserted into the side of the charging pile body 1, it can drive the limit block 67 to slide downward inside the limit slide groove 68.

[0059] One end of the limit connecting spring 64 is connected to the connecting shaft 63, and the other end of the limit connecting spring 64 is connected to the limit fixed housing 51. The two limit movable housings 52 are connected by a first connecting rod 61 and a second connecting rod 62. When the angle between the first connecting rod 61 and the second connecting rod 62 changes, the distance between the two limit movable housings 52 also changes.

[0060] When the limiting block 67 slides downward, it can drive the shaft connecting rod 65 to slide downward through the transmission connecting rod 66. When the shaft connecting rod 65 slides downward, it can drive the connecting shaft 63 to move downward and compress the limiting connecting spring 64.

[0061] When charging the car, first remove the charging gun 3 from the charging pile body 1. At this time, the limiting connection spring 64 rebounds and drives the connecting shaft 63 to move upward. When the connecting shaft 63 moves upward, it can drive the shaft connecting rod 65 to move synchronously. When the shaft connecting rod 65 moves, it can drive the limiting block 67 to slide upward inside the limiting slide groove 68 through the transmission connecting rod 66. When the connecting shaft 63 moves upward, it can drive the two limiting movable shells 52 to slide inside the limiting fixed shell 51 and approach each other through the first connecting rod 61 and the second connecting rod 62. The two limiting movable shells 52 are When the charging cable 2 is close to each other, the two limiting wheels 54 can be driven to clamp the charging cable 2. After the limiting wheels 54 clamp the charging cable 2, the movement of the charging cable 2 can drive the limiting wheels 54 to rotate, and the rotation direction of the limiting wheels 54 is limited by the engagement of the limiting ratchet 55 with the ratchet block 56, so that the charging cable 2 can only move from the inside of the charging pile body 1 to the outside of the charging pile body 1. During the movement of the charging cable 2, the limiting wheels 54 can be driven to rotate. After charging is completed, the charging gun 3 is inserted back into the charging pile body 1. At this time, the charging gun 3 can drive the limiting block 67 to move in the limiting slide. The inside of the groove 68 slides downward, and when the limit block 67 slides downward, the transmission connecting rod 66 can drive the shaft connecting rod 65 to move downward synchronously. When the shaft connecting rod 65 moves downward, the connecting shaft 63 can drive the connection point of the first connecting rod 61 and the second connecting rod 62 to move downward. When the connecting shaft 63 moves downward, the limit connecting spring 64 can be compressed. When the connection point of the first connecting rod 61 and the second connecting rod 62 moves downward, the two limit movable shells 52 can be driven away from each other, thereby releasing the clamping of the limit wheel 54 on the charging connection line 2, and then the cable recovery mechanism 4 rebounds to retract the excess charging cable 2 into the interior of the charging pile body 1, and can limit the position of the limit block 67 when the charging gun 3 is taken out and placed. The limit block 67 and the limit connection spring 64 limit the position of the connection between the first connecting rod 61 and the second connecting rod 62, thereby controlling the angle between the first connecting rod 61 and the second connecting rod 62. When the angle between the first connecting rod 61 and the second connecting rod 62 changes, the distance between the two limit movable shells 52 also changes accordingly, thereby controlling the clamping and release state of the limit wheel 54 on the charging cable 2.

[0062] Example 4

[0063] A control method based on a wall-mounted charging pile, using a charging pile as described in Examples 1 to 3, includes the following steps:

[0064] When charging the car, the charging gun 3 is first removed from the charging pile body 1. When the charging gun 3 is removed from the charging pile body 1, the cable limiting mechanism 5 can be driven by the transmission control mechanism 6 to clamp the charging connection cable 2;

[0065] Then pull the charging cable 2 outward through the charging gun 3, and plug the charging gun 3 into the charging port of the car to start charging the car;

[0066] After charging is completed, the charging gun 3 is inserted back into the charging pile body 1. When the charging gun 3 is inserted back into the charging pile body 1, the cable limiting mechanism 5 can be driven by the transmission control mechanism 6 to loosen the clamping of the charging connection cable 2.

[0067] After the cable restraining mechanism 5 releases the grip on the charging cable 2 , the cable collecting mechanism 4 can collect the excess charging cable 2 into the interior of the charging pile body 1 .

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
