Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging piles, and particularly relates to a suspension rack for moving a charging pack on a charging pile. Background Art

[0002] A charging pile is an energy replenishment 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 residential community parking lots. 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-computer 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 function of moving and changing tracks of the charging pack. For example, in the Chinese invention patent with the application number CN202310922077.3, it can solve the problem that the charging head cannot be pulled to the position of the vehicle for charging due to the small number of fixed charging piles. Therefore, most of the existing track-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.

[0005] However, the existing mobile charging piles are only provided with a steel frame for the charging pack to slide, resulting in instability of the charging pack during sliding. After sliding to the designated position, the charging pack is prone to skew relative to the designated position. Therefore, the utility model provides a suspension rack for moving a charging pack on a charging pile to solve the above problems. Content of the Utility Model

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a suspension rack for moving a charging pack on a charging pile to solve the problem of instability of the charging pack during sliding.

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

[0008] A suspension bracket for moving a charging pack on a charging pile, comprising two support ribs and two port brackets. Both port brackets are in a U-shape and are symmetrically arranged. A calibration ring is integrally formed on the lower side of the port bracket. The two support ribs are respectively fixed between the ends of the two port brackets. Three fixing members are slid back and forth inside the inner sides of the two support ribs close to each other. A charging pack is indirectly hung between the lower ends of the left and right fixing members. A calibration rod is fixedly connected to the upper side of the charging pack. When the charging pack moves to the lower part of the port bracket, the calibration rod is movably inserted into the calibration ring.

[0009] Through the above technical solution, the port bracket and the support ribs form a rectangular frame to support the fixing members and the charging pack. When the charging pack moves back and forth, the two support ribs limit the front and back movement trajectories of the fixing members and the charging pack, avoiding the charging pack from skewing. And after the charging pack moves back and forth to the lower part of the port bracket, the calibration rod is inserted into the calibration ring, further calibrating the position of the charging pack, preventing it from skewing, and preventing the charging pack from shaking left and right, making it more stable.

[0010] Preferably, two second rollers are rotatably arranged at the end of each fixing member through a rotating shaft, and the second rollers roll inside the support ribs.

[0011] Through the above technical solution, the second rollers reduce the friction between the fixing members and the support ribs, making the movement of the fixing members smoother.

[0012] Preferably, the front and rear ends of the calibration rod are both in a tapered shape.

[0013] Through the above technical solution, as long as the center of the calibration rod is located inside the calibration ring, the calibration rod can be accurately inserted into the calibration ring, that is, it is ensured that the calibration rod must be accurately inserted into the calibration ring.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In this device, the port bracket and the support ribs form a rectangular frame to support the fixing members and the charging pack. When the charging pack moves back and forth, the two support ribs limit the front and back movement trajectories of the fixing members and the charging pack, avoiding the charging pack from skewing. And after the charging pack moves back and forth to the lower part of the port bracket, the calibration rod is inserted into the calibration ring, further calibrating the position of the charging pack, preventing it from skewing, and preventing the charging pack from shaking left and right, making it more stable.

Detailed implementation manners

[0036] Next, each embodiment of the present utility model will be described in detail with reference to the reference appendices Figures 1 to 19 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.

[0037] As shown in the appendices Figure 1 - Appendices Figure 19 As shown, a suspension bracket for moving a charging pack on a charging pile includes a ceiling main track 1, a charging pack 6, a charging pack transmission device, a suspension bracket, and a hanger.

[0038] 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 rear sides of the suspension bracket, and the two support ribs 2 are the left and right sides of the suspension bracket;

[0039] 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;

[0040] The ends of the two fixing members 20 at the back are fixedly connected to a first sliding frame 15, the ends of the two middle fixing members 20 are fixedly connected to a second sliding frame 19, and the ends of the two fixing members 20 at the front are fixedly connected to 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;

[0041] 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 attached Figure 14 and attached 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 attached Figure 14In the state b and state c shown in the figure, the second slide 19 is located in the middle of the first slide 15 and the third slide 23. The upper ends of the first slide 15 and the third slide 23 are fixedly connected with elastic rods 67, and the other ends of the elastic rods 67 are fixedly connected with a holder 68. The lower end of the holder 68 is provided with a bayonet. After the first telescopic rod 17 moves through the third slide 23, the protrusion 37 of the first telescopic rod 17 moves through the bayonet of the holder 68. After the second telescopic rod 21 moves through the first slide 15, the protrusion 37 of the second telescopic rod 21 moves through the bayonet of the holder 68. The elastic rod 67 presses down the holder 68, and the holder 68 is clamped on the vertical surface of the protrusion 37, so that the holder 68 clamps the first telescopic rod 17 and the second telescopic rod 21 downward, so that the first telescopic rod 17 and the second telescopic rod 21 cannot move forward and backward at will.

[0042] The two supporting ribs 2 are fixedly connected with the main ceiling rails 1, and the two main ceiling rails 1 are in the same straight line. A sub-rail 18 is fixedly connected between the left and right fixing parts 20, that is, there are three sub-rails 18 in total, and the length of the sub-rail 18 is equal to the distance between the two main ceiling rails 1. Charging pack transmission devices are installed between the front sub-rail 18 and the suspension frame and between the rear sub-rail 18 and the suspension frame. One of the charging pack transmission devices drives the front sub-rail 18 to move forward and backward, and the other charging pack transmission device drives the rear sub-rail 18 to move forward and backward, so that any sub-rail 18 can move forward and backward between the two main ceiling rails 1, and can also move from the two The auxiliary rail 18 and the main rail 1 of the ceiling are both in an I-shape, so that rail grooves are formed in the front and rear ends of the auxiliary rail 18 and the main rail 1 of the ceiling. A hanger is slidably installed on the main rail 1 of the ceiling along the length direction. The number of hangers is not less than one. The lower end of each hanger is fixedly connected to a charging pack 6, that is, the first slide 15, the second slide 19 and the third slide 23 are used to hang the charging pack 6 through the auxiliary rail 18 and the hanger. The hanger moves between the auxiliary rail 18 and the main rail 1 of the ceiling. The upper front and rear ends of each hanger are fixed with a trapezoidal top block 11. When the hanger reaches the auxiliary rail 18, the trapezoidal top block 11 pushes the card seat 68 upward;

[0043] See attached Figure 19 An inner plate 79 is fixed inside the charging pack 6 , and a main control board 80 is fixed on the inner plate 79 .

[0044] As attached Figure 2As shown in the figure, 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 with 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 and sends a signal to the main control board 80 when the sensing end of the trigger switch 78 is touched 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;

[0045] 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. Moreover, 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.

[0046] As shown in the attached Figure 2 、attached Figure 5 、attached Figure 6 、attached Figure 7 and attached Figure 13 As shown in the attached figures, 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 assembly. The third power mechanism housing 33 and the motor housing 34 are internally connected 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 with a first screw 38. The first screw 38 is meshed with 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 that of the fourth gear 40, and the number of teeth of the third gear 39 is larger than that of the fourth gear 40. The fourth gear 40 is meshed with the fifth gear 41. The pitch circle diameter of the fifth gear 41 is larger than that of the fourth gear 40, and the number of teeth of the fifth gear 41 is larger than that of the fourth gear 40. The fifth gear 41 rotates inside the third power mechanism housing 33 through a rotating shaft;

[0047] One end of the rotating frame 31 rotates on the side of the third power mechanism housing 33 through a rotating shaft. The other end of the rotating frame 31 is fixedly connected to 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 third power mechanism housing 33. Clamping wheels 29 are rotatably arranged on the side surfaces of both the rotating frame 31 and the third power mechanism housing 33. The fifth gear 41 rotates coaxially and synchronously with the clamping wheel 29 on the third power mechanism housing 33. 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 movably passes between the two clamping wheels 29;

[0048] 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 together drive the charging cable 27 to move. And the spring 28 pulls the rotating frame 31, making the two clamping wheels 29 approach each other. On the one hand, it can firmly clamp the charging cable 27 to ensure that the friction 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, with a wide range of applications;

[0049] When the charging head 69 is moved 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. The main control board 80 controls the first motor 42 to stop working, thereby stopping the retraction of the charging cable 27;

[0050] 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 also meshes with the sixth gear 43. The sixth gear 43 and the second gear 32 rotate coaxially and synchronously. 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 at 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 rotation speeds of the two wire clamping wheels 29 are equal;

[0051] 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.

[0052] 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 through a rotating shaft within the upper end of the charger head housing 695. 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, and one end of the spring piece 76 upwardly pushes the end of the button 694 close to the charging signal feedback device 693;

[0053] 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;

[0054] A coiling motor signaler is fixed inside the charging head housing 695. The coiling motor signaler is electrically connected to the main control board 80, and 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 trigger 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 retract or release the charging cable 27.

The second power mechanism is installed inside the hanging bracket 8, and the second power mechanism drives the left two first rollers 9 to rotate;

[0056] The working principle of the suspension bracket is as follows: 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 secondary track 18, thereby driving the hanging bracket 8 to move along the ceiling main track 1 and the secondary 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 meshed 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.

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;

[0058] 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.

The first power mechanism housing 10 is fixed to the hanger 8. The through shaft 45 rotates through the side surface of the first power mechanism housing 10. Both the seventh gear 46 and the eighth gear 47 are located inside the first power mechanism housing 10;

[0060] 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;

[0061] 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.

[0062] As shown in the Figure 1 , Figure 2 , Figure 6 , Figure 9 , Figure 10 and the

[0063] shown in the attached drawings, 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 thread through the two nuts 70. 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 a front sub-rail 18 and a rear sub-rail 18.

[0064] 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. The output end of the third power transmission component drives the nut 70 to rotate.

[0065] As shown in the Figure 1 , Figure 2 , Figure 6 , Figure 9 , Figure 10As shown in the figure, the power assembly includes the second power mechanism housing 12, 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 second power mechanism housing 12 is fixed on the upper side of the charging pack 6. A second motor 54 is fixedly connected inside the second power mechanism housing 12. 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 to a second screw 55. The second screw 55 meshes with the fourteenth gear 56. The fourteenth gear 56 and the thirteenth gear 53 rotate coaxially and synchronously inside the second power mechanism housing 12. The thirteenth gear 53 meshes with the eleventh gear 51. The eleventh gear 51 and the twelfth gear 52 rotate coaxially and synchronously inside the second power mechanism housing 12. The twelfth gear 52 meshes 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 second power mechanism housing 12. A gear notch 48 is provided on the side of the ninth gear 49;

[0066] 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 on the ninth gear 49, the ninth gear 49 is temporarily not meshed with the fifteenth gear 59, avoiding the fifteenth gear 59 blocking the ninth gear 49 when the ninth gear 49 moves left and right. When the ninth gear 49 rotates, the ninth gear 49 meshes with the fifteenth gear 59. The fifteenth gear 59 and the second bevel gear 58 rotate coaxially and synchronously. The rotating shafts of the fifteenth gear 59 and the second bevel gear 58 pass 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 meshes with the first bevel gear 57. The first bevel gear 57 is fixedly sleeved outside the nut 70;

[0067] 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.

[0068] As shown in the appendix Figure 1 、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 to both of the two 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, the socket 5 is electrically connected to the charging cable 27, and the charging cable 27 is electrically connected to the main control board 80 through the socket 5 and the plug 4.

[0069] 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 a sharp cone.

[0070] 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.

[0071] The overall working principle is as follows:

[0072] Suspend the suspension bracket and the ceiling main track 1 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 meshes with the fifteenth gear 59, so that the charging pack transmission device drives the secondary track 18 to move back and forth;

[0073] The initial state is state b;

[0074] 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 the device. 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 side of the device;

[0075] Similarly, when the charging pack 6 is needed in the front area of the suspension rack, the hanger and the charging pack 6 move onto the front auxiliary track 18. The positions of the three auxiliary tracks 18 are switched 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 carries the hanger and the charging pack 6 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 remain stationary and return to the a state. Additionally, when in the c state, the hanger can also directly move onto 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;

[0076] Similarly, when there are vehicles using the charging pack 6 in both the front and rear areas of the suspension rack, the positions of the three auxiliary tracks 18 are as shown in the a state, enabling the hanger and the charging pack 6 to smoothly pass through the middle auxiliary track 18 and move onto another ceiling main track 1 to charge the vehicle on the right or left side of the device;

[0077] 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 clamping seat 68 are explained:

[0078] When in the a state, the hanger smoothly passes through the middle auxiliary track 18;

[0079] When in the b state, the front end of the first telescopic rod 17 passes forward through the inner perforation of the third carriage 23, and the elastic rod 67 presses the clamping seat 68 downward, causing the clamping seat 68 to clamp downward on the protruding 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 perforation of the first carriage 15, and the elastic rod 67 presses the clamping seat 68 downward, causing the clamping seat 68 to clamp downward on the protruding portion 37 at the rear end of the second telescopic rod 21. When the hanger moves onto the auxiliary track 18 on the first carriage 15, the trapezoidal top block 11 pushes the clamping seat 68 on the first carriage 15 upward, causing the clamping seat 68 to disengage from the rear end of the second telescopic rod 21;

[0080] When switching from the b state to the c state, the auxiliary track 18 on the first carriage 15 carries the hanger and the charging pack 6 and moves backward. 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;

[0081] When in the c state, the next hanger carries the charging pack 6 and moves rightward onto the auxiliary track 18 on the third carriage 23. At this time, the trapezoidal top block 11 pushes the clamping seat 68 on the third carriage 23 upward, causing the clamping seat 68 to disengage from the front end of the first telescopic rod 17;

[0082] 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 upwards. At this time, the first telescopic rod 17 can pass through the inner perforation in the third carriage 23, and the second telescopic rod 21 can pass through the inner perforation 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.
