Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle charging piles, and particularly relates to a multi-section variable-rail mobile charging pack hanger. 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 residential community parking lots. It can charge various models of electric vehicles by adjusting the 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 man-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 function of moving and changing the rail 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 charging piles and their fixed positions. 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, in the existing mobile charging piles, when the charging pack slides on the rail, it is easy to cause unstable movement. During sliding, the charging pack may deviate from the track or shake. The utility model provides a multi-section variable-rail mobile charging pack hanger to solve the above problems. Summary 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 multi-section variable-rail mobile charging pack hanger to solve the problem that the charging pack is prone to unstable movement when sliding on the rail.

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

[0008] A multi-section variable-rail mobile charging pack hanger includes a first sliding frame, a second sliding frame, and a third sliding frame;

[0009] A charging pack is indirectly hung below each of the first slide, the second slide and the third slide. Two inner through holes are arranged in each of the first slide, the second slide and the third slide. A first telescopic rod is movably passed through one of the inner through holes of the first slide and the second slide, and a second telescopic rod is movably passed through another inner through hole of the second slide and one of the inner through holes of the third slide. The first telescopic rod and the second telescopic rod are arranged in parallel.

[0010] Through the above technical solution, charging packs are indirectly hung underneath the first slide, the second slide and the third slide, which can drive multiple charging packs to move forward and backward respectively to achieve the purpose of track change movement, and when the first slide and the third slide move forward and backward, they are restricted by the first telescopic rod and the second telescopic rod, so that the first slide and the third slide can move forward and backward stably, avoiding deflection or shaking of the charging pack.

[0011] Preferably, the first telescopic rod is aligned with another inner through hole of the third slide, and the second telescopic rod is aligned with another inner through hole of the first slide;

[0012] With the above technical solution, the first telescopic rod can pass through the third slide when the first slide and the second slide are close to each other, and the second telescopic rod can pass through the first slide when the second slide and the third slide are close to each other.

[0013] Preferably, both ends of the first telescopic rod and both ends of the second telescopic rod are provided with protrusions;

[0014] Through the above technical solution, the provision of the protrusion can help to clamp the first telescopic rod and the second telescopic rod, thereby preventing the first telescopic rod and the second telescopic rod from being unable to be clamped due to smooth surfaces.

[0015] Preferably, the height of the protrusion is greater than the height of the inner through hole of the second slide, and the height of the protrusion is less than the height of the inner through holes of the first slide and the third slide;

[0016] The above technical solution can prevent the second slide from falling out of the first telescopic rod and the second telescopic rod, and will not hinder the first telescopic rod from entering and exiting the third slide, and will not hinder the second telescopic rod from entering and exiting the first slide.

[0017] Preferably, the front end of the raised portion at the rear of the first telescopic rod is located in the middle of the first telescopic rod, and the rear end of the raised portion at the front of the second telescopic rod is located in the middle of the second telescopic rod;

[0018] Through the above technical solution, when the first slide or the third slide moves between the two ceiling main rails, the second slide is located in the middle of the first slide and the third slide.

[0019] The beneficial effects of the utility model are:

[0020] Charging packs can be indirectly hung under the first slide, the second slide and the third slide, which can drive multiple charging packs to move forward and backward respectively to achieve the purpose of track change movement, and when the first slide and the third slide move forward and backward, they are restricted by the first telescopic rod and the second telescopic rod, so that the first slide and the third slide can move forward and backward stably, avoiding deflection or shaking of the charging pack.

Detailed implementation manners

[0041] The following will Figures 1 to 19 describe each embodiment of the present invention in detail. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0042] As shown in the Figure 1 - attached Figure 19 figure, a multi-stage variable-track mobile charging pack hanger includes a main ceiling track 1, a charging pack 6, a charging pack transmission device, a suspension frame and a hanger;

[0043] 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;

[0044] Inside the mutually close 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;

[0045] The ends of the two rear fixing members 20 are fixedly connected with a first sliding frame 15, the ends of the two middle fixing members 20 are fixedly connected with a second sliding frame 19, and the ends of the two front fixing members 20 are fixedly connected with a third sliding frame 23. Two inner through holes are provided inside 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;

[0046] 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 the appendix Figure 15 and 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.

[0047] 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;

[0048] 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 .

[0049] 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 holes 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;

[0050] 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, and the charging head 69 drops down to the ground, and then the charging head 69 can be used.

[0051] 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 component. The inside of 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 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 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 teeth of 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;

[0052] 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 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 third power mechanism housing 33. Thread clamping wheels 29 are rotatably arranged on the sides of both the rotating frame 31 and the third power mechanism housing 33. The fifth gear 41 rotates coaxially and synchronously with the thread clamping wheel 29 on the third power mechanism housing 33. A first power transmission assembly is installed between the fifth gear 41 and the thread clamping wheel 29 on the rotating frame 31. The fifth gear 41 drives the thread 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 thread clamping wheels 29;

[0053] 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 thread clamping wheels 29 to rotate. On the other hand, the fifth gear 41 drives the other thread clamping wheel 29 to rotate through the first power transmission assembly. The two thread clamping wheels 29 together drive the charging cable 27 to move. And the spring 28 pulls the rotating frame 31, so that the two thread clamping wheels 29 approach each other. On the one hand, the charging cable 27 can be firmly clamped, ensuring that the friction between the thread clamping wheel 29 and the charging cable 27 is sufficient, and the thread clamping wheel 29 can stably drive the charging cable 27 to move without slipping. On the other hand, the distance between the two thread clamping wheels 29 is adjustable, so that the two thread clamping wheels 29 can clamp charging cables 27 of various thicknesses, with a wide range of applications;

[0054] When the charging head 69 is moved into the charging head protective sleeve 7 and touches the induction 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, and then stops winding the charging cable 27;

[0055] 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 twentieth gear 66 meshes with 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 rotation speeds of the two wire clamping wheels 29 are equal;

[0056] 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.

[0057] Refer to the appendix Figure 16 - appendix Figure 18 , the charging 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 charging head housing 695. The charging insertion end 691 is inserted through the end of the charging head housing 695. The hand - held vibration sensor 692 and the charging signal feedback device 693 are fixed within the charging 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 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 charging 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. The other end of the button 694 is integrally formed with a chamfered chuck 73 in the direction of the charging insertion end 691. A spring piece 76 is fixed within the charging head housing 695. One end of the spring piece 76 upwardly pushes the end of the button 694 close to the charging signal feedback device 693;

[0058] After the end of the charging cable 27 penetrates into the charging head housing 695, it is electrically connected to the branch wire 75, and the branch wire 75 penetrates into the charging insertion end 691;

[0059] 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. 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. 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.

[0060] As shown in the attached Figure 1 attachment, Figure 2 attachment, Figure 6 attachment, Figure 8 attachment, Figure 11 and attachment Figure 12 As shown, the suspension bracket includes a hanging bracket 8, a first roller 9, and a second power mechanism. The lower side of the hanging bracket 8 is fixed to the upper side of the charging pack 6. At the four corners of the upper end of the hanging bracket 8, a first roller 9 is rotatably mounted 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, enabling the hanging bracket 8 to be movably suspended below the ceiling main track 1 or below the secondary track 18. 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;

[0061] 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.

[0062] As shown in the attached Figure 1 attachment, Figure 2 attachment, Figure 6 attachment, Figure 8 attachment, Figure 11 and attachment Figure 12As shown in the figure, the second power mechanism includes a fourth power mechanism housing 44, a third motor 60, a third screw 61, a sixteenth gear 62, a seventeenth gear 63, an eighteenth gear 64, and a second power transmission assembly. The fourth power mechanism housing 44 is fixed on 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;

[0063] 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.

[0064] As shown in the attached Figure 1 attachment Figure 2 attachment Figure 6 attachment Figure 8 attachment Figure 11 attachment Figure 12 As shown in the attached

[0065] 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;

[0066] 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.

[0070] , Figure 1 , Figure 2 , Figure 6 , Figure 9 , Figure 10 , 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.

[0068] 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.

[0069] 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 threaded over 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.

[0070] As shown in the appended Figure 1 , appended Figure 2 , appended Figure 6 , appended Figure 9 , and appended 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 to 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;

[0071] 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 in 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 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 is in meshing engagement with the first bevel gear 57. The first bevel gear 57 is fixedly sleeved outside the nut 70;

[0072] 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.

[0073] As shown in the appendix Figure 1 and appendix Figure 2 and appendixFigure 6 As shown, 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, 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.

[0074] As shown in the appendix Figure 1 As shown, a calibration rod 13 is fixedly connected to the upper side of the charging pack 6, and 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 sharp cones.

[0075] As shown in the appendix Figure 2 , as shown in the appendix Figure 6 and as shown in the appendix Figure 11 As shown, 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 together, the sensor 72 moves directly below the positioning bracket 71.

[0076] The overall working principle is as follows:

[0077] 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 meshes with the fifteenth gear 59, so that the charging pack transmission device drives the secondary track 18 to move back and forth;

[0078] The initial state is state b;

[0079] Refer to the appendix for combination 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. Also, 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;

[0080] 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 of the device;

[0081] 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 of the device;

[0082] 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:

[0083] When in the a state, the hanger smoothly passes through the middle auxiliary track 18;

[0084] 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 clamping seat 68 downward, so that the clamping 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 clamping seat 68 downward, so that the clamping 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 clamping seat 68 on the first carriage 15, so that the clamping seat 68 disengages from the rear end of the second telescopic rod 21;

[0085] When converting 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. At the same time, it will drive 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 push 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;

[0086] 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 clamping seat 68 on the third carriage 23, so that the clamping seat 68 disengages from the front end of the first telescopic rod 17;

[0087] When there are hangers and charging packs 6 on both the auxiliary tracks 18 on the first carriage 15 and the auxiliary tracks 18 on the third carriage 18, the third carriage 23 and the front auxiliary 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 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.
