Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging piles, in particular to a fixed-point triggering mechanism for charging pack movement. Background Art

[0002] A charging pile is an energy supplement device that provides power for electric vehicles. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall and installed in public buildings and parking lots of residential communities. It can charge various models of electric vehicles by adjusting voltage and current.

[0003] The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Generally, the charging pile provides two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe on the human-machine interaction operation interface provided by the charging pile to perform corresponding charging operations and print fee data. The display screen of the charging pile can display data such as the charging amount, fee, and charging time.

[0004] After long-term development, the functions of the charging pile are more perfect, including the charging pack moving and rail-changing function. For example, the Chinese invention patent with the application number CN202310922077.3 can solve the problem that the charging head cannot be pulled to the vehicle position for charging due to the small number of fixed charging piles. Therefore, most of the existing rail-changing charging piles are suspended on the ceiling of the basement. When needed, the whole charging pack is moved to the parking position of the vehicle, and then the charging head in the charging pack is pulled out to charge the vehicle.

[0005] However, the charging pack in the existing mobile charging pile always needs to be connected to a wire, and the other end of the wire is connected to the mains power. Then, when the charging pack moves, it needs to drag the wire to move, which is very inconvenient and prone to accidents. Therefore, the utility model provides a fixed-point triggering mechanism for charging pack movement to solve the above problems. Content of the Utility Model

[0006] In view of the above situation, in order to overcome the deficiencies of the prior art, the utility model provides a fixed-point triggering mechanism for charging pack movement to solve the problem that it is very inconvenient and prone to accidents when the charging pack drags the wire to move.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A fixed-point triggering mechanism for charging pack movement, comprising a suspension rack, sockets and plugs. A charging pack slides back and forth within the suspension rack. Sockets are fixedly connected to both the front and rear sides of the charging pack. Plugs are fixedly connected to both the front and rear ends within the suspension rack. After the suspension rack moves forward, the front plug is inserted into the front socket. After the suspension rack moves backward, the rear plug is inserted into the rear socket.

[0009] Through the above technical solution, the wire of the external mains power supply is connected to the plug. When the charging pack moves into the end of the suspension rack, the plug is connected to the socket, thereby supplying power to the charging pack. The socket always moves with the charging pack, while the plug and the wire do not move with the charging pack and are only electrically connected when the charging pack enters the interior of the suspension rack. Therefore, there is no need to constantly drag the plug and the wire, which is convenient to use.

[0010] Preferably, the input end of the plug is electrically connected to the output end of the external mains power supply, and the output end of the socket is electrically connected to the input end of the charging pack.

[0011] Preferably, positioning frames are fixedly provided at both the front and rear ends on the upper side of the suspension rack. Sensors are fixedly connected at intervals on the upper side of the charging pack. When the plug is inserted into the socket, the positioning frame is located at the recognition end of the sensor.

[0012] Through the above technical solution, when the plug is inserted into the socket and the positioning frame is located at the recognition end of the sensor, after the sensor sends the information to the external control center, the staff can remotely know that the socket and the plug are in use, that is, there is a charging pack being used here.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The wire of the external mains power supply is connected to the plug. When the charging pack moves into the end of the suspension rack, the plug is connected to the socket, thereby supplying power to the charging pack. The socket always moves with the charging pack, while the plug and the wire do not move with the charging pack and are only electrically connected when the charging pack enters the interior of the suspension rack. Therefore, there is no need to constantly drag the plug and the wire, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] The following will Figures 1 to 19 describe the embodiments of the present utility model in detail with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0036] As shown in the Figure 1 - accompanying Figure 19 drawings, a fixed-point triggering mechanism for the movement of a charging pack includes a main ceiling track 1, a charging pack 6, a charging pack transmission device, a suspension bracket and a hanger.

[0037] The suspension bracket includes two support ribs 2 and two port brackets 3. The two port brackets 3 are both in a U shape and symmetrically arranged. The two support ribs 2 are respectively fixed between the ends of the two port brackets 3, making the whole suspension bracket rectangular. The two port brackets 3 are the front and back sides of the suspension bracket, and the two support ribs 2 are the left and right sides of the suspension bracket;

[0038] Inside the mutually approaching sides of the two support ribs 2, three fixing members 20 slide back and forth. To reduce friction, at one end of each fixing member 20, two second rollers 36 are rotatably connected through a rotating shaft, and the second rollers 36 roll inside the support ribs 2;

[0039] The ends of the two rear fixing members 20 are both fixedly connected with a first sliding frame 15. The ends of the two middle fixing members 20 are both fixedly connected with a second sliding frame 19. The ends of the two front fixing members 20 are both fixedly connected with a third sliding frame 23. Two inner through holes are provided in each of the first sliding frame 15, the second sliding frame 19 and the third sliding frame 23. A first telescopic rod 17 passes through one of the inner through holes of the first sliding frame 15 and the second sliding frame 19 back and forth. A second telescopic rod 21 passes through one of the inner through holes of the second sliding frame 19 and the third sliding frame 23 back and forth. The first telescopic rod 17 is aligned with the other inner through hole of the third sliding frame 23, and the second telescopic rod 21 is aligned with the other inner through hole of the first sliding frame 15. The first telescopic rod 17 and the second telescopic rod 21 are arranged in parallel, so that when the first sliding frame 15 and the second sliding frame 19 approach each other, the second telescopic rod 21 is inserted backward into the inner through hole of the first sliding frame 15, and when the third sliding frame 23 and the second sliding frame 19 approach each other, the first telescopic rod 17 is inserted forward into the inner through hole of the second sliding frame 19;

[0040] Protrusion parts 37 are provided at the front and rear ends of the first telescopic rod 17 and the front and rear ends of the second telescopic rod 21. The height of the protrusion parts 37 is greater than the height of the inner through hole of the second sliding frame 19, so that the protrusion parts 37 cannot pass through the inner through hole of the second sliding frame 19, ensuring that the first telescopic rod 17 and the second telescopic rod 21 are always connected to the second sliding frame 19. The height of the protrusion parts 37 is less than the height of the inner through holes of the first sliding frame 15 and the third sliding frame 23, so that the protrusion parts 37 can penetrate into or out of the first sliding frame 15 and the third sliding frame 23. After referring to the appendix Figure 14 and appendix Figure 15 , the front end of the rear protrusion part of the first telescopic rod 17 is located in the middle of the first telescopic rod 17, and the rear end of the front protrusion part of the second telescopic rod 21 is located in the middle of the second telescopic rod 21, so that the first sliding frame 15, the second sliding frame 19 and the third sliding frame 23 move to as shown in the appendix Figure 14In the b state and the c state shown, the second carriage 19 is located exactly in the middle of the first carriage 15 and the third carriage 23. Elastic rods 67 are fixedly connected to the upper ends of the first carriage 15 and the third carriage 23. The other ends of the elastic rods 67 are fixedly connected to card seats 68. A bayonet is provided at the lower end of the card seat 68. After the first telescopic rod 17 passes through the third carriage 23, the protruding portion 37 of the first telescopic rod 17 passes through the bayonet of the card seat 68. After the second telescopic rod 21 passes through the first carriage 15, the protruding portion 37 of the second telescopic rod 21 passes through the bayonet of the card seat 68. The elastic rod 67 presses down the card seat 68, and the card seat 68 is stuck on the vertical surface of the protruding portion 37, so that the card seat 68 downwardly holds the first telescopic rod 17 and the second telescopic rod 21, making the first telescopic rod 17 and the second telescopic rod 21 unable to move back and forth arbitrarily;

[0041] Ceiling main rails 1 are fixedly connected to both of the two support ribs 2. The two ceiling main rails 1 are on the same straight line. A secondary rail 18 is fixedly connected between the left and right fixing members 20, that is, there are three secondary rails 18 in total. The length of the secondary rail 18 is equal to the distance between the two ceiling main rails 1. A charging pack transmission device is installed between the front secondary rail 18 and the suspension bracket and between the rear secondary rail 18 and the suspension bracket. One of the charging pack transmission devices drives the front secondary rail 18 to move back and forth, and the other charging pack transmission device drives the rear secondary rail 18 to move back and forth, so that any one of the secondary rails 18 can move back and forth between the two ceiling main rails 1 or can also leave between the two ceiling main rails 1. The secondary rail 18 and the ceiling main rail 1 are both in the shape of a capital "I", so that rail grooves are formed inside the front and rear ends of the secondary rail 18 and the ceiling main rail 1. A hanger is slidably installed on the ceiling main rail 1 along the length direction. The number of hangers is not less than one. A charging pack 6 is fixedly connected to the lower end of each hanger. That is, the first carriage 15, the second carriage 19 and the third carriage 23 suspend the charging pack 6 through the secondary rail 18 and the hanger. The hanger moves between the secondary rail 18 and the ceiling main rail 1. Trapezoidal top blocks 11 are fixed to the front and rear ends on the upper side of each hanger. When the hanger reaches the secondary rail 18, the trapezoidal top block 11 upwardly pushes the card seat 68;

[0042] Refer to the appendix Figure 19 Inside the charging pack 6, an inner plate 79 is fixed, and a main control board 80 is fixed on the inner plate 79.

[0043] As shown in the appendix Figure 2As shown, a reel shaft 24 is fixedly connected inside the charging pack 6. A wire reel 26 is rotatably sleeved outside the reel shaft 24. Threading holes 25 are circularly arrayed at the rear side of the wire reel 26. A charging wire 27 is wound inside the wire reel 26. One end of the charging wire 27 movably passes through the threading hole 25 and is connected to the main control board. The other end of the charging wire 27 movably passes out of the front end of the wire reel 26 and is fixedly connected to a charging head 69. A charging head protective sleeve 7 passes through the lower end of the charging pack 6. The charging wire 27 movably passes through the charging head protective sleeve 7. The charging head 69 is located inside the charging head protective sleeve 7. A trigger switch 78 is fixed inside the charging head protective sleeve 7. When the charging head 69 is moved into the charging head protective sleeve 7, it touches the sensing end of the trigger switch 78. The trigger switch 78 is electrically connected to the output end of the main control board 80. When the sensing end of the trigger switch 78 is touched, a signal is sent to the main control board 80 to confirm that the charging head 69 has been retracted. A third power mechanism is installed inside the charging pack 6, and the third power mechanism drives the charging wire 27 to move in and out of the charging pack 6;

[0044] The working principle of winding the charging wire 27 is as follows: The third power mechanism drives the charging wire 27 to move in and out of the charging pack 6. When the charging wire 27 enters the charging pack 6, it will push the wire reel 26 to rotate forward, so that the charging wire 27 is regularly wound up instead of being randomly coiled. And the charging head 69 is hidden inside the charging head protective sleeve 7 to protect the charging head 69. When the charging wire 27 is discharged from the charging pack 6, the wire reel 26 rotates in the reverse direction, so that the charging wire 27 is pulled out. The charging head 69 drops down to the ground, and then the charging head 69 can be used.

[0045] As shown in the appended Figure 2 , the appended Figure 5 , the appended Figure 6 , the appended Figure 7 , and the appended Figure 13 As shown, the third power mechanism includes a spring 28, a wire clamping wheel 29, a rotating frame 31, a third power mechanism housing 33, a motor housing 34, a first screw 38, a third gear 39, a fourth gear 40, a fifth gear 41, a first motor 42, and a first power transmission component. The inside of the third power mechanism housing 33 and the motor housing 34 are in communication and are both fixed inside the charging pack 6. A first motor 42 is fixedly connected inside the motor housing 34. The input end of the first motor 42 is electrically connected to the output end of the main control board. The output end of the first motor 42 is fixedly connected to a first screw 38. The first screw 38 is meshed with the teeth of the third gear 39. The third gear 39 and the fourth gear 40 rotate coaxially and synchronously inside the third power mechanism housing 33. The pitch circle diameter of the third gear 39 is larger than the pitch circle diameter of the fourth gear 40, and the number of teeth of the third gear 39 is more than the number of teeth of the fourth gear 40. The fourth gear 40 is meshed with the teeth of the fifth gear 41. The pitch circle diameter of the fifth gear 41 is larger than the pitch circle diameter of the fourth gear 40, and the number of teeth of the fifth gear 41 is more than the number of teeth of the fourth gear 40. The fifth gear 41 rotates inside the third power mechanism housing 33 through a rotating shaft;

[0046] One end of the rotating frame 31 rotates on the side of the housing 33 of the third power mechanism through a rotating shaft. The other end of the rotating frame 31 is fixedly connected with a spring 28. The other end of the spring 28 is fixedly connected to one end of a support rod 35. The other end of the support rod 35 is fixedly connected to the housing 33 of the third power mechanism. Clamping wheels 29 are rotatably mounted on the side surfaces of both the rotating frame 31 and the housing 33 of the third power mechanism. The fifth gear 41 rotates coaxially and synchronously with the clamping wheel 29 on the housing 33 of the third power mechanism. A first power transmission assembly is installed between the fifth gear 41 and the clamping wheel 29 on the rotating frame 31. The fifth gear 41 drives the clamping wheel 29 on the rotating frame 31 to rotate through the first power transmission assembly. The charging cable 27 passes through the space between the two clamping wheels 29 movably;

[0047] The working principle of the third power mechanism is as follows: After the first motor 42 is powered on, it drives the first screw rod 38 to rotate. The first screw rod 38 drives the third gear 39 to rotate. The third gear 39 drives the fourth gear 40 to rotate. The fourth gear 40 drives the fifth gear 41 to rotate. On the one hand, the fifth gear 41 drives one of the clamping wheels 29 to rotate. On the other hand, the fifth gear 41 drives the other clamping wheel 29 to rotate through the first power transmission assembly. The two clamping wheels 29 drive the charging cable 27 to move together. And the spring 28 pulls the rotating frame 31, so that the two clamping wheels 29 approach each other. On the one hand, the charging cable 27 can be clamped firmly, ensuring that the frictional force between the clamping wheel 29 and the charging cable 27 is sufficient, and the clamping wheel 29 can stably drive the charging cable 27 to move without slipping. On the other hand, the distance between the two clamping wheels 29 is adjustable, so that the two clamping wheels 29 can clamp charging cables 27 of various thicknesses, and the applicable range is wide;

[0048] When the charging head 69 is inserted into the charging head protective sleeve 7 and touches the sensing end of the trigger switch 78, the trigger switch 78 sends a signal to the main control board 80, and the main control board 80 controls the first motor 42 to stop working, thereby stopping the winding of the charging cable 27;

[0049] As shown in the attached Figure 2 、attached Figure 5 、attached Figure 6 、attached Figure 7 and attached Figure 13As shown in the figure, the first power transmission component includes a first gear 30, a second gear 32, a sixth gear 43 and a twentieth gear 66. The twentieth gear 66 rotates within the housing 33 of the third power mechanism through a rotating shaft. The twentieth gear 66 meshes with the fifth gear 41 and the sixth gear 43. The sixth gear 43 rotates coaxially and synchronously with the second gear 32. The rotating shafts of the sixth gear 43 and the second gear 32 pass through the front side of the housing 33 of the third power mechanism and the rear side of the rotating frame 31, enabling the rotating frame 31 to rotate around the rotating shafts of the sixth gear 43 and the second gear 32. The second gear 32 meshes with the first gear 30. The first gear 30 is fixed to the end of the rotating shaft of the wire clamping wheel 29 located on the rotating frame 31. Additionally, the tooth number ratio of the first gear 30 to the second gear 32 is equal to the tooth number ratio of the sixth gear 43 to the fifth gear 41 to ensure that the rotational speeds of the two wire clamping wheels 29 are equal;

[0050] The working principle of the first power transmission component is as follows: When the fifth gear 41 rotates, it drives the twentieth gear 66 to rotate. The twentieth gear 66 drives the sixth gear 43 to rotate. The sixth gear 43 drives the second gear 32 to rotate. The second gear 32 drives the first gear 30 to rotate. The first gear 30 drives the wire clamping wheel 29 to rotate.

[0051] Refer to the appendix Figure 16 - appendix Figure 18 , the charger head 69 includes a charging insertion end 691, a hand-held vibration sensor 692, a charging signal feedback device 693, a button 694 and a charger head housing 695. The charging insertion end 691 is inserted through the end of the charger head housing 695. The hand-held vibration sensor 692 and the charging signal feedback device 693 are fixed within the charger head housing 695. Both the hand-held vibration sensor 692 and the charging signal feedback device 693 are electrically connected to the main control board 80 to detect the signals before and after charging and send them to the main control board 80 for control. A button 694 rotates within the upper end of the charger head housing 695 through a rotating shaft. One end of the button 694 abuts against the sensing end of the charging signal feedback device 693. A chamfered chuck 73 is integrally formed at the other end of the button 694 in the direction of the charging insertion end 691. A spring piece 76 is fixed within the charger head housing 695. One end of the spring piece 76 pushes up the end of the button 694 close to the charging signal feedback device 693;

[0052] After the end of the charging cable 27 penetrates into the charger head housing 695, it is electrically connected to the branch wire 75, and the branch wire 75 penetrates into the charging insertion end 691;

[0053] Inside the charging head housing 695, a coiling motor signaler is fixed. The coiling motor signaler is electrically connected to the main control board 80. The output end of the coiling motor signaler is electrically connected to the first motor. The coiling motor signaler is the first coiling motor signaler 74 or the second coiling motor signaler 77. When the coiling motor signaler is the first coiling motor signaler 74, the triggering end of the first coiling motor signaler 74 abuts against the lower side of the button 694, and the first coiling motor signaler 74 is electrically connected to the main control board 80. When the coiling motor signaler is the second coiling motor signaler 77, the second coiling motor signaler 77 is a signal board, and the second coiling motor signaler 77 is electrically connected to the main control board 80. When the coiling motor signaler receives a signal from the main control board 80, it can control the third power mechanism to take in or release the charging cable 27.

The lower side of the suspension frame 8 is fixed to the upper side of the charging pack 6. Four corners of the upper end of the suspension frame 8 are each rotatably provided with a first roller 9 through a rotating shaft. The front two first rollers 9 roll in the front track groove of the ceiling main track 1, and the rear two first rollers 9 roll in the rear track groove of the ceiling main track 1, so that the suspension frame 8 can be movably suspended below the ceiling main track 1 or below the auxiliary track 18. The second power mechanism is installed inside the suspension frame 8, and the second power mechanism drives the left two first rollers 9 to rotate;

[0055] The working principle of the suspension bracket is: the second power mechanism drives the first roller 9 to rotate forward and backward. The first roller 9 rolls in the ceiling main track 1 and the auxiliary track 18, thereby driving the suspension frame 8 to move along the ceiling main track 1 and the auxiliary track 18, and thereby driving the charging pack 6 to move.

The fourth power mechanism housing 44 is fixed to the hanger 8. A third motor 60 is fixedly connected inside the fourth power mechanism housing 44. The input end of the third motor 60 is electrically connected to the main control board 80. The output end of the third motor 60 is fixedly connected to a third screw 61. The third screw 61 is in meshing engagement with the sixteenth gear 62. The sixteenth gear 62 and the seventeenth gear 63 rotate coaxially and synchronously inside the fourth power mechanism housing 44. The seventeenth gear 63 is in meshing engagement with the eighteenth gear 64. The eighteenth gear 64 rotates coaxially and synchronously with one of the first rollers 9. A second power transmission assembly is installed between the eighteenth gear 64 and the other first roller 9, and they rotate synchronously through the power transmission of the second power transmission assembly;

[0057] The working principle of the second power mechanism is as follows: After the third motor 60 is powered on, it drives the third screw 61 to rotate. The third screw 61 drives the sixteenth gear 62 to rotate. The sixteenth gear 62 drives the seventeenth gear 63 to rotate. The seventeenth gear 63 drives the eighteenth gear 64 to rotate. The eighteenth gear 64 drives one of the first rollers 9 to rotate. The eighteenth gear 64 drives the other first roller 9 to rotate through the second power transmission assembly, so as to make the two first rollers 9 roll.

Both the seventh gear 46 and the eighth gear 47 are located inside the first power mechanism housing 10;

[0059] The tooth number ratio of the seventh gear 46 and the eighth gear 47 is equal to the tooth number ratio of the nineteenth gear 65 and the eighteenth gear 64, so that the rotational speeds of the front and rear first rollers 9 are equal;

[0060] The working principle of the second power transmission component is as follows: The eighteenth gear 64 drives the nineteenth gear 65 to rotate, the nineteenth gear 65 drives the through shaft 45 to rotate, the through shaft 45 drives the seventh gear 46 to rotate, the seventh gear 46 drives the eighth gear 47 to rotate, and the eighth gear 47 drives the first roller 9 to rotate.

[0061] As shown in the attached Figure 1 attachment, Figure 2 attachment, Figure 6 attachment, Figure 9 attachment, and Figure 10 attachment, the charging pack transmission device includes a power component, a transmission mechanism housing 22, a third power transmission component, a lead screw 16, and a nut 70. The lead screw 16 is fixed between two port brackets 3. The two ends of the lead screw 16 respectively pass through the two nuts 70 in a threaded manner. The two nuts 70 respectively rotate within the two transmission mechanism housings 22. The two transmission mechanism housings 22 are respectively fixedly connected to the upper sides of the front sub-rail 18 and the rear sub-rail 18.

[0062] The power component is installed on the upper side of the charging pack 6. When the charging pack 6 moves below the sub-rail 18, the output end of the power component is connected to the input end of the third power transmission component. The third power transmission component is installed within the transmission mechanism housing 22, and the output end of the third power transmission component drives the nut 70 to rotate.

[0063] The working principle of the charging pack transmission device is as follows: The power component drives the nut 70 to rotate forward and backward through the third power transmission component. Since the nut 70 is threadedly sleeved outside the lead screw 16, the nut 70 moves forward and backward while rotating forward and backward, causing the nut 70 to push the transmission mechanism housing 22 forward and backward, and the transmission mechanism housing 22 drives the sub-rail 18 to move forward and backward.

[0064] As shown in the attached Figure 1 attachment, Figure 2 attachment, Figure 6 attachment, Figure 9 attachment, and Figure 10As shown in the figure, the power assembly includes the housing 12 of the second power mechanism, the ninth gear 49, the tenth gear 50, the eleventh gear 51, the twelfth gear 52, the thirteenth gear 53, the second motor 54, the second screw 55 and the fourteenth gear 56. The housing 12 of the second power mechanism is fixed to the upper side of the charging pack 6. The second motor 54 is fixedly connected inside the housing 12 of the second power mechanism. The input end of the second motor 54 is electrically connected to the main control board 80. The output end of the second motor 54 is fixedly connected with the second screw 55. The second screw 55 is in meshing engagement with the fourteenth gear 56. The fourteenth gear 56 and the thirteenth gear 53 rotate coaxially and synchronously inside the housing 12 of the second power mechanism. The thirteenth gear 53 is in meshing engagement with the eleventh gear 51. The eleventh gear 51 and the twelfth gear 52 rotate coaxially and synchronously inside the housing 12 of the second power mechanism. The twelfth gear 52 is in meshing engagement with the tenth gear 50. The tenth gear 50 and the ninth gear 49 rotate coaxially and synchronously. The ninth gear 49 is the output end of the power assembly and is located outside the housing 12 of the second power mechanism. A gear notch 48 is provided on the side of the ninth gear 49;

[0065] The third power transmission assembly includes a first bevel gear 57, a second bevel gear 58 and a fifteenth gear 59. When the charging pack 6 moves below the secondary track 18, the ninth gear 49 moves below the fifteenth gear 59. Due to the gear notch 48 existing on the ninth gear 49, the ninth gear 49 is temporarily not in meshing engagement with the fifteenth gear 59, preventing the fifteenth gear 59 from blocking the ninth gear 49 when the ninth gear 49 moves left and right. When the ninth gear 49 rotates, the ninth gear 49 is in meshing engagement with the fifteenth gear 59. The fifteenth gear 59 and the second bevel gear 58 rotate coaxially and synchronously. The rotating shaft of the fifteenth gear 59 and the second bevel gear 58 passes through the transmission mechanism housing 22, such that the fifteenth gear 59 is located outside the transmission mechanism housing 22 while the second bevel gear 58 is located inside the transmission mechanism housing 22. The second bevel gear 58 is in meshing engagement with the first bevel gear 57. The first bevel gear 57 is fixedly sleeved outside the nut 70;

[0066] The working principle of the power assembly and the third power transmission assembly is as follows: After the second motor 54 is powered on, it drives the second screw 55. The second screw 55 drives the fourteenth gear 56 to rotate. The fourteenth gear 56 drives the thirteenth gear 53 to rotate. The thirteenth gear 53 drives the eleventh gear 51 to rotate. The eleventh gear 51 drives the twelfth gear 52 to rotate. The twelfth gear 52 drives the tenth gear 50 to rotate. The tenth gear 50 drives the ninth gear 49 to rotate. The ninth gear 49 drives the fifteenth gear 59 to rotate. The fifteenth gear 59 drives the second bevel gear 58 to rotate. The second bevel gear 58 drives the first bevel gear 57 to rotate. The first bevel gear 57 drives the nut 70 to rotate.

[0067] As shown in the appendix Figure 1 and appendix Figure 2 and appendixFigure 6 As shown in the figure, sockets 5 are fixedly connected to both the front and rear sides of the suspension bracket. Plugs 4 are fixedly connected inside both port brackets 3. After the suspension bracket moves forward, the front plug 4 is inserted into the front socket 5. After the suspension bracket moves backward, the rear plug 4 is inserted into the rear socket 5. The plug 4 is electrically connected to the main control board 80, and the socket 5 is electrically connected to the charging cable 27. The charging cable 27 is electrically connected to the main control board 80 through the socket 5 and the plug 4.

[0068] As attached Figure 1 As shown in the figure, a calibration rod 13 is fixedly connected to the upper side of the charging pack 6. A calibration ring 14 is integrally formed on the lower side of the port bracket 3. When the charging pack 6 moves to the lower side of the port bracket 3, the calibration rod 13 is movably inserted into the calibration ring 14. In order to facilitate the accurate and deviation-free insertion of the calibration rod 13 into the calibration ring 14, both the front and rear ends of the calibration rod 13 are in the shape of pointed cones.

[0069] As attached Figure 2 and attached Figure 6 and attached Figure 11 As shown in the figure, positioning brackets 71 are fixedly connected to both the front and rear ends of one of the support ribs 2. Sensors 72 are fixedly connected to the upper sides of the first sliding bracket 15 and the third sliding bracket 23. After the plug 4 and the socket 5 are plugged in, the sensor 72 moves directly below the positioning bracket 71.

[0070] The overall working principle is as follows:

[0071] The suspension bracket and the ceiling main track 1 are hung on the roof. The hanger drives the charging pack 6 to move left and right until the hanger and the charging pack 6 move directly below the suspension bracket. The hanger is on the secondary track 18. At this time, the output end of the power assembly is connected to the input end of the third power transmission assembly, that is, the ninth gear 49 is meshed with the fifteenth gear 59, so that the charging pack transmission device drives the secondary track 18 to move back and forth;

[0072] The initial state is state b;

[0073] Combined with reference to the attached Figure 14 , when the charging pack 6 is needed in the rear area of the suspension bracket, the hanger and the charging pack 6 move to the rear secondary track 18. The positions of the three secondary tracks 18 are switched from state b back to state c, that is, the rear secondary track 18 moves backward, driving the hanger and the charging pack 6 to move backward. The charging pack 6 charges the vehicle behind this device. And when the rear secondary track 18 moves backward, it will drive the front secondary track 18 and the third sliding bracket 23 to move backward together through the first telescopic rod 17 and the second telescopic rod 21 to reach state c. In addition, when in state b, the hanger can also directly move to the left ceiling main track 1 or the right ceiling main track 1 through the rear secondary track 18 to charge the vehicle on the left or right of this device;

[0074] Similarly, when the charging pack 6 is needed in the front area of the suspension rack, the hanger and the charging pack 6 move to the front auxiliary track 18, and the positions of the three auxiliary tracks 18 are changed from the c state to the a state, that is, the front auxiliary track 18 moves forward, and the middle auxiliary track 18 moves between the two ceiling main tracks 1, so that the front auxiliary track 18 drives the hanger and the charging pack 6 to move forward, and the charging pack 6 charges the vehicle in front of the device. At this time, the rear auxiliary track 18 and the first carriage 15 do not move and return to the a state. In addition, when in the c state, the hanger can also directly move to the left ceiling main track 1 or the right ceiling main track 1 through the auxiliary track 18 to charge the vehicle on the left or right side of the device;

[0075] Similarly, when there are vehicles using the charging pack 6 in both the front area and the rear area of the suspension rack, the positions of the three auxiliary tracks 18 are as shown in the a state, so that the hanger and the charging pack 6 can smoothly pass through the middle auxiliary track 18 and move to another ceiling main track 1 to charge the vehicle on the right or left side of the device;

[0076] In addition, based on the above, the working principles of the trapezoidal top block 11, the first telescopic rod 17, the second telescopic rod 21, the elastic rod 67 and the card seat 68 are explained:

[0077] When in the a state, the hanger smoothly passes through the middle auxiliary track 18;

[0078] When in the b state, the front end of the first telescopic rod 17 passes forward through the inner through hole of the third carriage 23, and the elastic rod 67 presses the card seat 68 downward, so that the card seat 68 downwardly clamps the convex portion 37 at the front end of the first telescopic rod 17. The rear end of the second telescopic rod 21 passes through the inner through hole of the first carriage 15, and the elastic rod 67 presses the card seat 68 downward, so that the card seat 68 downwardly clamps the convex portion 37 at the rear end of the second telescopic rod 21. When the hanger moves to the auxiliary track 18 on the first carriage 15, the trapezoidal top block 11 upwardly pushes the card seat 68 on the first carriage 15, so that the card seat 68 disengages from the rear end of the second telescopic rod 21;

[0079] When changing from the b state to the c state, the auxiliary track 18 on the first carriage 15 drives the hanger and the charging pack 6 to move backward, and at the same time, it drives the front auxiliary track 18 and the third carriage 23 to move backward together through the first telescopic rod 17 and the second telescopic rod 21, and pushes the second carriage 19 to move backward together until the auxiliary track 18 on the third carriage 23 moves between the two ceiling main tracks 1, that is, in the c state;

[0080] When in the c state, the next hanger drives the charging pack 6 to move rightward to the auxiliary track 18 on the third carriage 23. At this time, the trapezoidal top block 11 upwardly pushes the card seat 68 on the third carriage 23, so that the card seat 68 disengages from the front end of the first telescopic rod 17;

[0081] When there are hangers and charging packs 6 on both the secondary track 18 on the first carriage 15 and the secondary track 18 on the third carriage 18, the third carriage 23 and the front secondary track 18 move forward. It should be noted that the clamping seats 68 on both the first carriage 15 and the third carriage 23 are pushed upward. At this time, the first telescopic rod 17 can pass through the inner through-hole in the third carriage 23, and the second telescopic rod 21 can pass through the inner through-hole in the first carriage 21. Then, the rear end of the second telescopic rod 121 pulls the second carriage 19 forward to return to state a.
