Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging piles, and in particular to a mobile charging pile with a position adjustment function. Background Art

[0002] Charging pile is a charging device that provides power for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or wall and installed in public buildings and residential parking lots. It can charge various types of electric vehicles according to 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. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging operations and print cost data. The charging pile display can display data such as charging capacity, cost, and charging time;

[0004] After long-term development, the functions of charging piles have become more complete, including the function of moving the charging pack to change tracks. For example, the Chinese invention patent with application number CN202310922077.3 can solve the problem that the charging head cannot be pulled to the car position for charging due to the small number of charging piles and their immobility. Therefore, most of the existing track-changing charging piles are suspended on the ceiling of the basement. When needed, the charging pack is moved as a whole to the parking position of the car, and then the charging head in the charging pack is pulled out for charging;

[0005] However, when the existing mobile charging piles are transporting charging packs, multiple charging packs are easily blocked from each other. For example, when the charging pack on the left moves to the right, the charging pack on the right will block it, so the charging pack cannot reach the specified position. Therefore, the present invention provides a mobile charging pile with a position adjustment function to solve the above problem. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a mobile charging pile with a position adjustment function to solve the problem that multiple charging packs are easily blocked from each other when transporting charging packs in the above-mentioned existing mobile charging piles.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A mobile charging pile with a position adjustment function, comprising a ceiling main track, a charging pack, a charging pack transmission device, a suspension frame and a hanger;

[0009] Three fixing members are provided in opposite sides of the suspension frame for sliding forward and backward, the ends of the two rear fixing members are fixedly connected to the first slide, the ends of the two middle fixing members are fixedly connected to the second slide, and the ends of the two front fixing members are fixedly connected to the third slide, the first slide, the second slide and the third slide are each provided with two inner through holes, a first telescopic rod passes through one of the inner through holes of the first slide and the second slide and moves forward and backward, a second telescopic rod passes through another inner through hole of the second slide and one of the inner through holes of the third slide and moves forward and backward, the first telescopic rod is aligned with the other inner through hole of the third slide, and the second telescopic rod is aligned with the other inner through hole of the first slide;

[0010] The left and right sides of the suspension frame are fixedly connected with ceiling main rails, the two ceiling main rails are in the same straight line, a hanger is slidably installed on the ceiling main rail along the length direction, the number of the hangers is not less than one, the lower end of each hanger is fixedly connected with a charging pack, and a sub-rail is fixedly connected between the left and right fixing parts, the hanger moves between the sub-rail and the ceiling main rail, and a charging pack transmission device is installed between the front sub-rail and the rear sub-rail and the suspension frame. When the hanger reaches the sub-rail, the charging pack transmission device drives the sub-rail to move forward and backward. The length of the sub-rail is equal to the spacing between the two ceiling main rails. When the sub-rail moves between the two ceiling main rails, the suspension frame moves between the sub-rail and the two ceiling main rails;

[0011] Through the above technical solution, the hanger and the charging pack can move left and right along the main rail and the auxiliary rail of the ceiling to change the left and right position of the charging pack. When the hanger and the charging pack move to the auxiliary rail, the charging pack transmission device drives the auxiliary rail to move forward and backward, and then drives the charging pack to move forward and backward to change the front and rear position of the charging pack. When the charging pack transmission device drives one of the auxiliary rails to move forward and backward, the first slide, the second slide and the third slide are driven to move accordingly through the first telescopic rod and the second telescopic rod, so that the other auxiliary rails are moved between the two main rails of the ceiling to ensure that the movement of one of the charging packs forward and backward will not hinder the left and right movement of other charging packs.

[0012] Preferably, the charging pack transmission device comprises a power assembly, a transmission mechanism housing, a third power transmission assembly, a lead screw and a nut, wherein the lead screw is fixed between the two port frames, and the two ends of the lead screw are respectively threaded through two nuts, and the two nuts are respectively rotated in two transmission mechanism housings, and the two transmission mechanism housings are respectively fixedly connected to the upper sides of a front auxiliary track and a rear auxiliary track;

[0013] The power assembly is installed on the upper side of the charging pack, and the third power transmission assembly is installed in the transmission mechanism housing. When the charging pack and the hanger move to the secondary track, the output end of the power assembly is connected to the input end of the third power transmission assembly, and the output end of the third power transmission assembly drives the nut to rotate;

[0014] Through the above technical solution, when the hanger has not moved to the secondary track, the output end of the power assembly will not be connected to the input end of the third power transmission assembly, will not drive the nut to rotate, will not drive the transmission mechanism housing to move forward and backward, and will not drive the secondary track to move forward and backward. Only when the hanger moves to the secondary track will the output end of the power assembly be connected to the input end of the third power transmission assembly to drive the secondary track to move forward and backward. That is, the forward and backward movement of the charging pack and the hanger is controlled by the power assembly on itself, and the forward and backward movement of each charging pack and the hanger can be controlled individually.

[0015] Preferably, the upper ends of the first slide and the third slide are both fixedly connected with an elastic rod, the other ends of the elastic rod are fixedly connected with a holder, the lower end of the holder is provided with a bayonet, the front end of the first telescopic rod moves forward through the third slide and then moves through the bayonet of the holder, and the rear end of the second telescopic rod moves backward through the first slide and then moves through the bayonet of the holder;

[0016] Through the above technical solution, the elastic rod presses the socket downward, the socket on the third slide clamps the front end of the first telescopic rod, and the socket on the first slide clamps the rear end of the second telescopic rod, so that the third slide can be fixed to the first telescopic rod, and the first slide can be fixed to the second telescopic rod, so that the first slide, the second slide and the third slide can move forward and backward together.

[0017] Preferably, a trapezoidal top block is fixed to the front and rear ends of the upper side of each hanger, and when the hanger reaches the auxiliary track, the trapezoidal top block pushes the seat upward;

[0018] Through the above technical solution, when the hanger moves to the secondary track, the trapezoidal top block pushes the seat upward, allowing the first slide and the third slide to move freely forward and backward, so that the first slide, the second slide and the third slide can be separated.

[0019] Preferably, the auxiliary rail and the main ceiling rail are both in an I-shape, so that rail grooves are formed in the front and rear ends of the auxiliary rail and the main ceiling rail, and the hanger moves in the rail groove between the auxiliary rail and the main ceiling rail.

[0020] The beneficial effects of the present invention are:

[0021] 1. The hanger and the charging pack can move left and right along the main rail and the auxiliary rail of the ceiling to change the left and right position of the charging pack. When the hanger and the charging pack move to the auxiliary rail, the charging pack transmission device drives the auxiliary rail to move forward and backward, and then drives the charging pack to move forward and backward to change the front and rear position of the charging pack. When the charging pack transmission device drives one of the auxiliary rails to move forward and backward, the first slide, the second slide and the third slide are driven to move accordingly through the first telescopic rod and the second telescopic rod, so that the other auxiliary rails are moved between the two main rails of the ceiling to ensure that the movement of one charging pack forward and backward will not hinder the left and right movement of other charging packs.

[0022] 2. The elastic rod presses the seat downward, and the seat on the third slide clamps the front end of the first telescopic rod, and the seat on the first slide clamps the rear end of the second telescopic rod, so that the third slide can be fixed to the first telescopic rod, and the first slide can be fixed to the second telescopic rod, so that the first slide, the second slide and the third slide can move forward and backward together. When the hanger moves to the secondary track, the trapezoidal top block pushes the seat upward, so that the first slide and the third slide can move freely forward and backward, so that the first slide, the second slide and the third slide can be separated.

[0023] 3. In summary, the device can drive the charging pack to move left and right and forward and backward. When the charging pack moves left and right, other charging packs can move forward and backward to avoid hindering the left and right movement of the charging pack. When the charging pack moves forward and backward, other sub-rails can be moved between the two ceiling main rails to facilitate the left and right movement of other charging packs. In this way, the left and right movement and forward and backward movement of multiple charging packs will not interfere with each other. It is flexible to use and can control the separation and relative fixation of the first slide, the second slide and the third slide, that is, it can adjust different sub-rails to move between the two ceiling main rails.

[0044] The following will refer to the attached Figures 1 to 19 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0045] As attached Figure 1 -Attached Fig.19 As shown, a mobile charging pile with position adjustment function includes a ceiling main track 1, a charging pack 6, a charging pack transmission device, a suspension frame and a hanger;

[0046] The suspension frame includes two supporting ribs 2 and two port frames 3. The two port frames 3 are both in the shape of a square and are symmetrically arranged. The two supporting ribs 2 are respectively fixed between the ends of the two port frames 3, so that the entire suspension frame is rectangular. The two port frames 3 are the front and rear sides of the suspension frame, and the two supporting ribs 2 are the left and right sides of the suspension frame.

[0047] Three fixing members 20 are provided inside the side of the two supporting ribs 2 that are close to each other and slide forward and backward. In order to reduce friction, two second rollers 36 are provided at one end of each fixing member 20 and rotate through a rotating shaft. The second rollers 36 roll inside the supporting ribs 2.

[0048] The ends of the two rear fixing members 20 are fixedly connected to the first slide 15, the ends of the two middle fixing members 20 are fixedly connected to the second slide 19, and the ends of the two front fixing members 20 are fixedly connected to the third slide 23. The first slide 15, the second slide 19 and the third slide 23 are each provided with two inner through holes, and the first telescopic rod 17 is movably passed through one of the inner through holes of the first slide 15 and the second slide 19, and the other inner through hole of the second slide 19 and one of the inner through holes of the third slide 23 are connected to each other. A second telescopic rod 21 movably passes through the holes, the first telescopic rod 17 is aligned with another inner through hole of the third slide 23, the second telescopic rod 21 is aligned with another inner through hole of the first slide 15, the first telescopic rod 17 and the second telescopic rod 21 are arranged in parallel, so that when the first slide 15 and the second slide 19 are close to each other, the second telescopic rod 21 is inserted backward into the inner through hole of the first slide 15, so that when the third slide 23 and the second slide 19 are close to each other, the first telescopic rod 17 is inserted forward into the inner through hole of the second slide 19;

[0049] The front and rear ends of the first telescopic rod 17 and the front and rear ends of the second telescopic rod 21 are both provided with protrusions 37, and the height of the protrusions 37 is greater than the height of the inner through hole of the second slide 19, so that the protrusions 37 cannot pass through the inner through hole of the second slide 19, ensuring that the first telescopic rod 17 and the second telescopic rod 21 are always connected to the second slide 19, and the height of the protrusions 37 is less than the height of the inner through holes of the first slide 15 and the third slide 23, so that the protrusions 37 can pass into or out of the first slide 15 and the third slide 23, and then refer to the attached Fig.14 and attached Fig.15 The front end of the rear raised portion of the first telescopic rod 17 is located in the middle of the first telescopic rod 17, and the rear end of the front raised portion of the second telescopic rod 21 is located in the middle of the second telescopic rod 21, so that the first slide 15, the second slide 19 and the third slide 23 move to the positions shown in the attached figure. Fig.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.

[0050] 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;

[0051] See attached Fig.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 .

The trigger switch 78 is electrically connected to the output end of the main control board 80, and 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 in the charging bag 6, and the third power mechanism drives the charging line 27 to enter and exit the charging bag 6;

[0053] The working principle of the winding charging cable 27 is as follows: the third power mechanism drives the charging cable 27 in and out of the charging bag 6. When the charging cable 27 enters the charging bag 6, it pushes the winding wheel 26 to rotate forward, so that the charging cable 27 is regularly wound up instead of being randomly wound up, and the charging head 69 is hidden in the charging head protective cover 7 to protect the charging head 69. When the charging cable 27 is discharged from the charging bag 6, the winding wheel 26 rotates in the opposite direction, so that the charging cable 27 is pulled out, and the charging head 69 falls to the ground, and the charging head 69 can be used.

[0054] As attached Figure 2 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 and attached Fig.13 As shown, the third power mechanism includes a spring 28, a 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 third power mechanism housing 33 and the motor housing 34 are internally connected and are both fixed in the charging bag 6. The motor housing 34 is fixedly connected with the first motor 42. 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 the first screw 38. The first screw The third gear 38 is meshed with the third gear 39, the third gear 39 and the fourth gear 40 are coaxially rotated synchronously in the third power mechanism housing 33, the tooth top circle diameter of the third gear 39 is greater than the tooth top circle diameter of the fourth gear 40, and the number of teeth of the third gear 39 is greater than the number of teeth of the fourth gear 40, the fourth gear 40 is meshed with the fifth gear 41, the tooth top circle diameter of the fifth gear 41 is greater than the tooth top circle diameter of the fourth gear 40, and the number of teeth of the fifth gear 41 is greater than the number of teeth of the fourth gear 40, and the fifth gear 41 is rotated in the third power mechanism housing 33 through the rotating shaft;

The side of the rotating frame 31 and the side of the third power mechanism housing 33 are both rotated with a clamping wheel 29, and the fifth gear 41 and the clamping wheel 29 on the third power mechanism housing 33 rotate coaxially and synchronously. A first power transmission component is installed between the fifth gear 41 and the clamping wheel 29 on the rotating frame 31, and the fifth gear 41 drives the clamping wheel 29 on the rotating frame 31 to rotate through the first power transmission component, and the charging line 27 moves through the two clamping wheels 29;

[0056] The working principle of the third power mechanism is as follows: after the first motor 42 is energized, it drives the first screw 38 to rotate, the first screw 38 drives the third gear 39 to rotate, the third gear 39 drives the fourth gear 40 to rotate, and 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, and on the other hand, the fifth gear 41 drives the other clamping wheel 29 to rotate through the first power transmission component. The two clamping wheels 29 drive the charging line 27 to move together, and the spring 28 pulls the rotating frame 31, so that the two clamping wheels 29 are close to each other. On the one hand, the charging line 27 can be clamped forcefully to ensure that the friction between the clamping wheels 29 and the charging line 27 is sufficient, and the clamping wheels 29 stably drive the charging line 27 to move without slipping. On the other hand, the spacing between the two clamping wheels 29 is adjustable, so that the two clamping wheels 29 can clamp charging lines 27 of various thicknesses, and have a wide range of applications.

[0057] When the charging head 69 moves into the charging head protective cover 7 and contacts 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 reeling of the charging cable 27;

[0058] As attached Figure 2 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 and attached Fig.13As shown, the first power transmission assembly includes a first gear 30, a second gear 32, a sixth gear 43 and a twentieth gear 66, the twentieth gear 66 rotates in the third power mechanism housing 33 through a rotating shaft, the twentieth gear 66 is meshed with the fifth gear 41, the twentieth gear 66 is meshed with the sixth gear 43, the sixth gear 43 and the second gear 32 rotate synchronously on the same axis, the rotating shafts of the sixth gear 43 and the second gear 32 rotate through the front side of the third power mechanism housing 33 and the rear side of the rotating frame 31, so that the rotating frame 31 rotates around the rotating shafts of the sixth gear 43 and the second gear 32, the second gear 32 is meshed with the first gear 30, and the first gear 30 is fixed to the end of the rotating shaft of the clamping wheel 29 located on the rotating frame 31, in addition, the gear ratio of the first gear 30 to the second gear 32 is equal to the gear ratio of the sixth gear 43 to the fifth gear 41, so as to ensure that the rotation speeds of the two clamping wheels 29 are equal;

[0059] The working principle of the first power transmission component is: 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, and the first gear 30 drives the clamping wheel 29 to rotate.

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

[0064] The working principle of the suspension bracket is: the second power mechanism drives the first roller 9 to rotate forward and reversely, and the first roller 9 rolls in the main ceiling track 1 and the auxiliary track 18, thereby driving the hanger 8 to move along the main ceiling track 1 and the auxiliary track 18, thereby driving the charging pack 6 to move.

The third screw 61 is meshed with the sixteenth gear 62. The sixteenth gear 62 and the seventeenth gear 63 coaxially rotate synchronously in the fourth power mechanism housing 44. The seventeenth gear 63 is meshed with the eighteenth gear 64. The eighteenth gear 64 is coaxially rotated synchronously with one of the first rollers 9. The second power transmission component is installed between the eighteenth gear 64 and the other first roller 9 and rotates synchronously through the power transmission of the second power transmission component.

[0066] The working principle of the second power mechanism is: after the third motor 60 is energized, 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, and the eighteenth gear 64 drives the other first roller 9 to rotate through the second power transmission component, so as to make the two first rollers 9 roll.

[0068] The gear ratio of the seventh gear 46 to the eighth gear 47 is equal to the gear ratio of the nineteenth gear 65 to the eighteenth gear 64, so that the rotation speeds of the front and rear first rollers 9 are equal;

[0069] The working principle of the second power transmission component is: 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] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 , Attachment Fig. 9 and attached Fig.10 As shown, the charging pack transmission device includes a power assembly, a transmission mechanism housing 22, a third power transmission assembly, a lead screw 16 and a nut 70. The lead screw 16 is fixed between the two port frames 3. Both ends of the lead screw 16 are respectively threaded through the two nuts 70. The two nuts 70 are respectively rotated in the two transmission mechanism housings 22. The two transmission mechanism housings 22 are respectively fixedly connected to the upper sides of a front auxiliary track 18 and a rear auxiliary track 18.

[0071] The power assembly is installed on the upper side of the charging pack 6. When the charging pack 6 moves to the bottom of the auxiliary track 18, the output end of the power assembly is connected to the input end of the third power transmission assembly. The third power transmission assembly is installed in the transmission mechanism housing 22. The output end of the third power transmission assembly drives the nut 70 to rotate.

[0072] The working principle of the charging pack transmission device is as follows: the power component drives the nut 70 to rotate forward and reverse through the third power transmission component. Since the nut 70 is threadedly sleeved on the outside of the screw 16, the nut 70 rotates forward and reverse while moving forward and backward, so that the nut 70 pushes the transmission mechanism housing 22 forward and backward, and the transmission mechanism housing 22 drives the secondary track 18 to move forward and backward.

[0073] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 , Attachment Fig. 9 and attached Fig.10As shown, the power assembly includes a second power mechanism housing 12, a ninth gear 49, a tenth gear 50, an eleventh gear 51, a twelfth gear 52, a thirteenth gear 53, a second motor 54, a second screw 55 and a fourteenth gear 56. The second power mechanism housing 12 is fixed to the upper side of the charging pack 6. The second motor 54 is fixedly connected to 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 the second screw 55. The second screw 55 and the fourteenth gear 56 are connected to each other. The fourteenth gear 56 and the thirteenth gear 53 are coaxially and synchronously rotated in the second power mechanism housing 12, the thirteenth gear 53 and the eleventh gear 51 are meshed with each other, the eleventh gear 51 and the twelfth gear 52 are coaxially and synchronously rotated in the second power mechanism housing 12, the twelfth gear 52 and the tenth gear 50 are meshed with each other, the tenth gear 50 and the ninth gear 49 are coaxially and synchronously rotated, the ninth gear 49 is the output end of the power assembly and is located outside the second power mechanism housing 12, and a gear notch 48 is provided on the side of the ninth gear 49;

[0074] 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 to the bottom of the auxiliary track 18, the ninth gear 49 moves to the bottom of the fifteenth gear 59. Due to the gear notch 48 in the ninth gear 49, the ninth gear 49 is temporarily not meshed with the fifteenth gear 59, so as to avoid 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 rotates synchronously with the second bevel gear 58 on the same axis. The rotating shafts of the fifteenth gear 59 and the second bevel gear 58 rotate through the transmission mechanism housing 22, so that the fifteenth gear 59 is located outside the transmission mechanism housing 22 and 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, and the first bevel gear 57 is fixedly sleeved outside the nut 70.

[0075] The working principle of the power assembly and the third power transmission assembly is: after the second motor 54 is energized, 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, and the first bevel gear 57 drives the nut 70 to rotate.

[0076] As attached Figure 1 , Attachment Figure 2 and attached Figure 6 As shown, the front and rear sides of the suspension bracket are fixedly connected with sockets 5, and the two port brackets 3 are fixedly connected with plugs 4.

The plug 4 is electrically connected to the main control board 80, and the socket 5 is electrically connected to the charging line 27. The charging line 27 is electrically connected to the main control board 80 through the socket 5 and the plug 4.

[0077] As attached 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 frame 3. When the charging pack 6 moves to the bottom of the port frame 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, the front and rear ends of the calibration rod 13 are both cone-shaped.

[0078] As attached Figure 2 , Attachment Figure 6 and attached Fig.11 As shown, the front and rear ends of one of the support ribs 2 are fixedly connected to a positioning frame 71, the upper side of the first slide 15 and the upper side of the third slide 23 are fixedly connected to a sensor 72, and after the plug 4 and the socket 5 are plugged in, the sensor 72 moves to the bottom of the positioning frame 71.

[0079] The overall working principle is:

[0080] The hanger and the ceiling main track 1 are hung on the roof, and the hanger drives the charging pack 6 to move left and right until the hanger and the charging pack 6 move to the bottom of the hanger, and the hanger is on the auxiliary 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 and the fifteenth gear 59 are meshed, so that the charging pack transmission device drives the auxiliary track 18 to move forward and backward;

[0081] The initial state is state b;

[0082] Please refer to the attached Fig.14 When the charging pack 6 is needed in the rear area of ​​the suspension rack, the hanger and the charging pack 6 move to the rear auxiliary track 18, and the positions of the three auxiliary tracks 18 are converted from state b to state c, that is, the rear auxiliary track 18 moves backward, driving the hanger and the charging pack 6 to move backward, and the charging pack 6 charges the vehicle behind the device, and when the rear auxiliary track 18 moves backward, the front auxiliary track 18 and the third slide 23 are driven 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 move directly to the left ceiling main track 1 or the right ceiling main track 1 through the rear auxiliary track 18 to charge the vehicle on the left or right side of the device;

[0083] Similarly, when the charging pack 6 is needed in the front area of ​​the hanger, the hanger and the charging pack 6 are moved to the front auxiliary track 18, and the positions of the three auxiliary tracks 18 are converted from state c to state a, 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 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 slide 15 do not move and return to state a. In addition, when in state c, the hanger can also move directly 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;

[0084] Similarly, when there are vehicles using the charging pack 6 in the front and rear areas of the hanger, the positions of the three auxiliary tracks 18 are as shown in state a, 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 to the right or left of the device;

[0085] In addition, based on the above, the working principle of the trapezoidal top block 11, the first telescopic rod 17, the second telescopic rod 21, the elastic rod 67 and the holder 68 is explained:

[0086] When in state a, the hanger passes smoothly through the middle auxiliary track 18;

[0087] When in state b, the front end of the first telescopic rod 17 passes forward through the inner hole of the third slide 23, and the elastic rod 67 presses the holder 68 downward, so that the holder 68 clamps the protrusion 37 of the front end of the first telescopic rod 17 downward, and the rear end of the second telescopic rod 21 passes through the inner hole of the first slide 15, and the elastic rod 67 presses the holder 68 downward, so that the holder 68 clamps the protrusion 37 of the rear end of the second telescopic rod 21 downward, and when the hanger moves to the secondary track 18 on the first slide 15, the trapezoidal top block 11 pushes the holder 68 on the first slide 15 upward, so that the holder 68 is disengaged from the rear end of the second telescopic rod 21;

[0088] When switching from state b to state c, the auxiliary track 18 on the first slide 15 carries the hanger and the charging pack 6 to move backwards, and at the same time, the auxiliary track 18 and the third slide 23 in front are driven to move backwards together through the first telescopic rod 17 and the second telescopic rod 21, and the second slide 19 is pushed to move backwards together, until the auxiliary track 18 on the third slide 23 moves between the two ceiling main tracks 1, that is, it is in state c;

[0089] In state c, the next hanger carries the charging pack 6 and moves rightward to the secondary track 18 on the third slide 23. At this time, the trapezoidal top block 11 pushes up the holder 68 on the third slide 23, so that the holder 68 is disengaged from the front end of the first telescopic rod 17.

[0090] When the sub-rail 18 on the first slide 15 and the sub-rail 18 on the third slide 18 are both supported by the hanger and the charging pack 6, the third slide 23 and the front sub-rail 18 move forward. It is worth noting that the holders 68 on the first slide 15 and the third slide 23 are both pushed upward. At this time, the first telescopic rod 17 can pass through the inner hole in the third slide 23, and the second telescopic rod 21 can pass through the inner hole in the first slide 21. Then the rear end of the second telescopic rod 121 pulls the second slide 19 forward and returns to state a.
