Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a modular intelligent dynamic power distribution charging pile. Background Art

[0002] With the development of electric vehicles, the total power consumption of charging piles is huge. More electric vehicle charging piles will be built in China. If so many electric vehicle charging stations are not uniformly dispatched and managed, a large number of charging stations will work arbitrarily and form impact loads, which will inevitably have a certain impact on the power grid. Therefore, through intelligent dynamic power distribution, the charging power can be adjusted in real time to meet the changing charging needs of electric vehicles and improve charging efficiency.

[0003] For example, a patent with a patent authorization publication number of CN220562566U and an announcement date of 2024-03-08 discloses a car charging device for a new energy charging pile, including a charging body and a protective shell, the upper surface of the charging body is fixedly connected to an inverted U-shaped support frame, and an inverted U-shaped cavity is opened inside the support frame, and the inner bottom wall of the cavity is fixedly inlaid with two first bearings, and the inner ring of each of the first bearings is fixedly connected to a threaded screw, and the inner top wall of the cavity is fixedly connected to a forward and reverse motor, and the top end of one of the threaded screws is fixedly connected to the output end of the forward and reverse motor, and the outer surface of each threaded screw is fixedly connected to a pulley. However, the above scheme still has certain shortcomings in actual use. For example, during use, the above device faces the problem of hanging the charging gun connecting line and protecting the charging interface. Since the charging gun of the charging pile needs to be connected to the car through a connecting line for charging, it is easy for the connecting line to be too long and dragged on the ground. Long-term friction can easily cause external damage to the connecting line, resulting in poor charging contact, and the user may forget to plug the charging gun back, which can easily cause the charging interface to be soaked in water or sand, causing damage and affecting subsequent use, especially in rainy, snowy or dusty environments.

[0004] Based on the above situation, the present invention proposes a modular intelligent dynamic power distribution charging pile. Summary of the invention

[0005] In order to overcome the shortcomings of lack of suspension of charging gun connecting wires and protection of charging interfaces, the present invention proposes a modular intelligent dynamic power distribution charging pile.

[0006] The technical solution of the present invention is: a modular intelligent dynamic power distribution charging pile, including a charging pile, a charging cable fixedly connected to the charging pile, a charging connector installed at the movable end of the charging cable, a locking piece fixedly connected to the outer side of the charging connector, a fixed frame fixedly connected to the side of the charging pile close to the charging cable, an electric slide rail installed on the fixed frame, a sliding block slidably connected to the electric slide rail, a rotating shaft rotatably connected to the sliding block, a conveying wheel fixedly connected to the side of the rotating shaft away from the fixed frame, a first straight gear fixedly connected to the side of the rotating shaft close to the sliding block, a first rack fixedly connected to the side of the fixed frame close to the electric slide rail, a protective shell fixedly connected to the side of the fixed frame close to the charging connector, and the charging cable passes through the top wall of the protective shell.

[0007] In one embodiment, the first rack meshes with the first spur gear.

[0008] In one of the embodiments, there is also a sealing mechanism for covering the charging connector to prevent water vapor in the air from entering therein, the sealing mechanism is arranged on the locking member, the sealing mechanism includes a first sliding frame, the first sliding frame is slidably connected to the locking member, a first spring is connected between the first sliding frame and the locking member, the first spring is wound on the first sliding frame, a symmetrically distributed second rack is fixedly connected to the first sliding frame, a rotating member is rotatably connected to a side of the locking member close to the first spring, a symmetrically distributed missing gear is fixedly connected to the rotating member, a sealing sleeve is fixedly connected to the rotating member, and the sealing sleeve is snap-fitted with the charging connector.

[0009] In one embodiment, the missing gear is meshed with the adjacent second rack.

[0010] In one of the embodiments, there is also an anti-collision mechanism for preventing the charging connector from colliding with the protective shell when the charging cable is transported. The anti-collision mechanism is arranged on the protective shell. The anti-collision mechanism includes a second sliding frame, which is slidably connected to the top wall of the protective shell. A symmetrically distributed second spring is connected between the second sliding frame and the protective shell. A first magnet evenly distributed along the circumferential direction is fixed to the bottom of the second sliding frame, and a second magnet is fixed to the top of the charging connector.

A second spur gear is fixedly connected to a side of the screw close to the third rack. A dryer is installed in the third sliding frame.

[0013] In one embodiment, the second spur gear meshes with the third rack.

DETAILED DESCRIPTION

[0029] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Embodiment 1: A modular intelligent dynamic power distribution charging pile, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a charging pile 1, a charging line 11 is fixedly connected to the middle of the front side of the charging pile 1, a charging connector 12 is installed at the movable end of the charging cable 11, a locking member 13 is fixedly connected to the outer side of the charging connector 12, a fixing frame 21 is fixedly connected to the right front side of the charging pile 1, an electric slide rail 2 is installed at the front of the fixing frame 21, a sliding block 22 is slidably connected to the electric slide rail 2, a rotating shaft 221 is rotatably connected to the sliding block 22, a conveying wheel 23 is fixedly connected to the left side of the rotating shaft 221, an arc-shaped sliding groove is opened on the conveying wheel 23 for facilitating the fitting with the charging line 11, a first straight gear 26 is fixedly connected to the right side of the rotating shaft 221, a first rack 25 is fixedly connected to the side of the fixing frame 21 close to the electric slide rail 2, a protective shell 24 is fixedly connected to the side of the fixing frame 21 close to the charging connector 12, the charging line 11 passes through the top wall of the protective shell 24, and the first rack 25 is meshed with the first straight gear 26.

[0031] like Figure 5 and Figure 6 As shown, it also includes a sealing mechanism for covering the charging connector 12 to prevent water vapor in the air from entering therein, the sealing mechanism is arranged on the locking member 13, and the sealing mechanism includes a first sliding frame 3, the first sliding frame 3 is slidably connected to the rear part of the locking member 13, a first spring 34 is connected between the first sliding frame 3 and the locking member 13, the first spring 34 is wound on the first sliding frame 3, the left and right sides of the first sliding frame 3 are fixedly connected with the second rack 33, the rear side of the locking member 13 is rotatably connected with a rotating member 31, the left and right sides of the rotating member 31 are fixedly connected with a missing gear 32, the rotating member 31 is fixedly connected with a sealing sleeve 35, the sealing sleeve 35 is snap-fitted with the lower part of the charging connector 12, and the missing gear 32 is meshed with the adjacent second rack 33.

[0032] When using the device, the owner can first control the electric slide rail 2 to drive the sliding block 22 to move downward, thereby driving the rotating shaft 221, the first spur gear 26, and the conveying wheel 23 to move downward together. Since the first spur gear 26 is meshed with the first rack 25, the first spur gear 26 will drive the conveying wheel 23 to rotate forward through the rotating shaft 221. The conveying wheel 23 rotating forward will convey the charging cable 11 forward, and the conveying wheel 23 will convey the charging cable 11 forward while moving downward. Under the action of the self-gravity of the charging cable 11 and the charging connector 12, the charging connector 12 will drive the charging cable 11, the locking member 13, the sealing sleeve 35, the first sliding frame 3, the second rack 33, etc. to move downward until they extend out of the protective shell 24.

[0033] At this time, the car owner can hold the charging connector 12 and insert it into the charging socket of the electric car, thereby driving the first sliding frame 3 to contact the charging socket, and the charging socket will resist the first sliding frame 3 to drive the second rack 33 to move upward, and the first spring 34 will be deformed. Since the second rack 33 is engaged with the missing gear 32, the missing gear 32 drives the rotating member 31 and the sealing sleeve 35 to flip and open backward, and the sealing sleeve 35 no longer covers the charging port of the charging connector 12. The charging connector 12 can be inserted into the charging socket for charging. When the electric car is charged, the charging connector 12 is first pulled out of the charging socket, and the charging socket no longer resists the first sliding frame 3. Under the elastic force of the first spring 34, the first sliding frame 3 will drive the second rack 33 to move downward and reset, so that the sealing sleeve 35 flips forward and closes to cover the charging port of the charging connector 12.

[0034] Then control the electric slide rail 2 to drive the sliding block 22 to move upward and reset. According to the previous steps, the conveying wheel 23 will rotate backward and move upward to reset. The conveying wheel 23 will convey the charging cable 11 backward, and the charging connector 12 will also return to the protective shell 24. In summary, first, through the cooperation of the second rack 33 and the missing gear 32, the sealing sleeve 35 can be automatically opened when the charging connector 12 is inserted into the charging socket, and automatically closed when the charging connector 12 is unplugged, so that the charging socket of the charging connector 12 can be in a protected state when not in use, effectively preventing external wind and sand from entering the charging port and protecting the charging interface from damage. Then, through the mutual cooperation of the electric slide rail 2, the sliding block 22, the first spur gear 26, and the first rack 25, the charging cable 11 can always be in a suspended state, the charging connector 12 will not contact the ground, the charging cable 11 is prevented from contacting the ground, and wear is reduced. At the same time, the charging connector 12 is prevented from entering water and sand, thereby extending the service life and improving the applicability and durability of the charging pile 1.

[0035] Embodiment 2: Based on embodiment 1, Figure 7 As shown, it also includes an anti-collision mechanism for preventing the charging connector 12 from colliding with the protective shell 24 when the charging cable 11 is transported. The anti-collision mechanism is arranged on the protective shell 24. The anti-collision mechanism includes a second sliding frame 4. The second sliding frame 4 is slidably connected to the top wall of the protective shell 24. A second spring 43 symmetrically distributed on the left and right is connected between the second sliding frame 4 and the protective shell 24. Three first magnets 41 uniformly distributed along the circumferential direction are fixedly connected to the bottom of the second sliding frame 4, and a second magnet 42 is fixedly connected to the top of the charging connector 12. The three first magnets 41 and the second magnet 42 are magnetically matched.

[0036] Initially, the second spring 43 is in a deformed state. When the charging connector 12 drives the charging line 11, the locking member 13, the sealing sleeve 35, the first sliding frame 3, the second rack 33, etc. to move downward until they extend out of the protective shell 24, the charging connector 12 will also drive the second sliding frame 4 to move downward together with the first magnet 41 through the second magnet 42. When the owner holds the charging connector 12 and inserts it into the charging socket, the second magnet 42 will separate from the first magnet 41. At the same time, under the elastic action of the second spring 43, the second sliding frame 4 will drive the first magnet 41 to stay at the lower opening of the protective shell 24. When the head 12 is pulled out from the charging socket and returned to the protective shell 24, according to the previous steps, the second magnet 42 on the charging connector 12 is attracted together with the first magnet 41. As the charging line 11 is transported backward, the charging connector 12 will drive the second sliding frame 4 to move upward and reset through the second magnet 42 and the first magnet 41, and the second spring 43 returns to the deformed state. In summary, through the magnetic attraction cooperation between the first magnet 41 and the second magnet 42, the charging connector 12 can move up and down in a straight line, avoiding damage caused by collision between the charging connector 12 and the inner wall of the protective shell 24, thereby improving the convenience and safety of use.

[0037] like Figure 8 and Fig. 9 As shown, it also includes a drying mechanism for keeping the charging connector 12 dry. The drying mechanism is arranged on the sliding block 22. The drying mechanism includes a fixing member 5. The fixing member 5 is fixedly connected to the front side of the sliding block 22. A third rack 51 is fixedly connected to the bottom of the fixing member 5. A guide frame 52 is fixedly connected to the front right side of the fixing frame 21. A screw rod 53 is rotatably connected to the right side of the protective shell 24. A third sliding frame 55 is threadedly connected to the screw rod 53. The third sliding frame 55 is slidably connected to the guide frame 52. A second spur gear 54 is fixedly connected to the left side of the screw rod 53. A dryer 56 is installed in the third sliding frame 55. The second spur gear 54 is meshed with the third rack 51. An arc-shaped slide groove is opened on the protective shell 24, and the third sliding frame 55 slides in the arc-shaped slide groove.

[0038] Initially, the third sliding frame 55 is located in the protective shell 24, and the dryer 56 keeps the charging connector 12 dry. When the sliding block 22 moves up and down, the sliding block 22 will drive the third rack 51 to move up and down through the fixing member 5. Since the third rack 51 is meshed with the second spur gear 54, the screw 53 is driven to rotate forward or reverse. When the screw 53 rotates forward, the third sliding frame 55 is driven to drive the dryer 56 to move right, and the third sliding frame 55 will move out of the protective shell 24. Conversely, when the screw 53 is reversed, the third sliding frame 55 is driven to drive the dryer 56 to move left into the protective shell 24. In summary, through the cooperation of the third rack 51, the second spur gear 54, and the screw 53, the dryer 56 can automatically enter and exit the protective shell 24 as needed, thereby preventing the charging connector 12 from being poorly charged or damaged due to moisture, further improving the practicality of the charging pile 1 and its adaptability to harsh environments.

[0039] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
