Description

Technical Field

[0001] The present application belongs to the technical field of charging equipment, and in particular, relates to an adaptive charging bow and a charging device. Background Art

[0002] The charging device has a swing arm and a charging bow head, and the swing arm can swing to drive the charging bow head to contact or detach from the charging port on the charging vehicle.

[0049] Embodiment 1

[0050] See Figures 1 to 6 As shown, the adaptive pantograph head 4 provided in the embodiment of the present application includes: a main beam 41, two side arm assemblies, a plurality of limit members 44, and an elastic member 45. The two side arm assemblies are respectively arranged at both ends of the main beam 41. Each side arm assembly has two swing rods 42. The two swing rods 42 are both movably connected to the main beam 41. The two swing rods 42 extend towards both sides of the main beam 41 respectively. The swing rod 42 is connected with an insulator 43. Each of the limit members 44 is connected to the main beam 41. Each of the limit members 44 is in limit cooperation with each of the swing rods 42 to limit the swing angle of each of the swing rods 42. The elastic member 45 is connected to the main beam 41. The elastic member 45 abuts against the side of each swing rod 42 away from the insulator 43, so that each swing rod 42 has a tendency to tilt towards the insulator side.

[0051] When the charging vehicle in the present application parks on an uneven road surface or the tire pressures on both sides of the charging vehicle are inconsistent, resulting in the left and right sides of the charging port being tilted up and down, during the process of the adaptive pantograph head 4 approaching and connecting to the charging vehicle, the electrode on the insulator 43 of one swing rod 42 in the side arm assembly first contacts an interface of the charging vehicle, and the other swing rod 42 of the side arm assembly will tilt down until the electrode on the insulator 43 thereon contacts the other interface of the charging vehicle whose position becomes lower due to the tilt of the vehicle body. When the charging vehicle in the present application parks on an uneven road surface or the tire pressures on both sides of the charging vehicle are inconsistent, resulting in the tilt of the charging port, the pantograph head 4 can automatically tilt by a corresponding angle, so that the electrodes on each insulator 43 on the pantograph head 4 can respectively stably connect or contact with the corresponding interfaces on the charging port, the charging circuit is not easily disconnected, and the charging vehicle can be stably charged.

[0052] In a possible implementation, see Figure 5 As shown, the limit member 44 includes a first limit beam 441 and a second limit beam 442. The first limit beam 441 and the second limit beam 442 are respectively located on both sides of the corresponding swing rod 42 along the swing direction.

[0053] In this embodiment, the two limit beams can limit the swing angle of the swing rod 42, so that the swing rod 42 can move within the effective range. For example, the swing rod 42 can adjust the tilt angle within the range of ±2 to 3°, which is relatively small. When the tilt angle of the vehicle is within this range, the docking with the charging bow head 4 can be successfully completed. When the swing rod 42 swings to the extreme position, the limit beam can contact the swing rod 42, so that the electrode on the insulator 43 of the swing rod 42 can be stably docked with the charging port on the battery swap vehicle without being easily disengaged.

[0054] In a possible implementation, the two side end surfaces of the swing rod 42 along the swing direction are respectively provided with a first upper inclined surface 421 and a first lower inclined surface 422. The first limit beam 441 is provided with a second upper inclined surface on one side facing the swing rod 42, and the second limit beam 442 is provided with a second lower inclined surface on one side facing the swing rod 42. When the swing rod 42 swings to the first extreme position, the first upper inclined surface 421 and the second upper inclined surface are in contact with each other, and when the swing rod 42 swings to the second extreme position, the second lower inclined surface and the second lower inclined surface are in contact with each other.

[0055] In this embodiment, when the swing rod 42 swings to the extreme position, the inclined surface on the swing rod 42 and the inclined surface on the limiting beam can fit smoothly. This surface-to-surface fitting has good stability and reduces wear between the swing rod 42 and the limiting beam.

[0056] In one possible embodiment, see Figure 5 As shown, the position-limiting member 44 further includes a connecting beam 443 connecting the first position-limiting beam 441 and the second position-limiting beam 442. A ring body 46 is sleeved on the main beam 41. Extension rods are arranged on both sides of the ring body 46, and the extension rods are connected to the connecting beam 443. The ring body 46 is connected to the main beam 41, and the ring body 46 and the main beam 41 are limitedly matched, and the ring body 46 will not rotate relative to the main beam 41. An extension rod is arranged on both sides of a ring body 46 to respectively connect the connecting beams 443 on the position-limiting member 44 on both sides.

[0057] In a possible implementation, the elastic member 45 includes a spiral portion 451 and torsion arms 452 located at both ends of the spiral portion 451 , the spiral portion 451 is sleeved on the main beam 41 , and the two torsion arms 452 respectively abut against one end of the corresponding rocker 42 away from the insulator 43 .

[0058] The first limiting beam 441 is located at the top of the second limiting beam 442. In this embodiment, the two torsion arms 452 apply forces to the two swing rods 42 respectively, causing the two swing rods 42 to fit against the second limiting beam 442 on the corresponding limiting member 44 respectively. So that in the normal state, the two swing rods 42 are both stably supported on the second limiting beam 442 of the limiting member 44. When the top of the battery swapping vehicle is tilted and during the docking charging of the adaptive charging bow head 4 and the battery swapping vehicle, the two swing rods 42 can automatically adjust the tilt angle. The greater the tilt angle of the swing rod 42, the greater the elastic force received by the torsion arm 452, enabling the electrodes on the insulator 43 of the swing rod 42 to be more stably docked with the charging port and not easily disconnected.

[0059] In a possible embodiment, referring to Figure 5 as shown, the main beam 41 has a main shaft, a limiting section, an end shaft, and an anti - detachment sleeve 411. The limiting section is connected to the end of the main shaft, the end shaft is connected to the end of the limiting section, the anti - detachment sleeve 411 is fixedly sleeved on the end shaft. The cross - section of the limiting section can be non - circular, such as polygonal. The central hole of the toroidal body can also be a polygonal hole. The toroidal body is sleeved on this limiting section and will not rotate around the limiting section. The diameter of the end shaft is smaller than that of the limiting section and the main shaft. The anti - detachment sleeve 411 is sleeved on the end of the end shaft. The ends of the two swing rods 42 are rotatably sleeved on the end shaft. The swing rod 42 is limited between the limiting section and the anti - detachment sleeve 411. The spiral part 451 is sleeved on the anti - detachment sleeve 411. Among them, the anti - detachment sleeve 411 can be thread - connected to the end shaft.

[0060] In a possible embodiment, the adaptive charging bow head 4 includes a connecting seat 47. The insulator 43 is connected to the connecting seat 47, and the connecting seat 47 is hinged to the swing rod 42.

[0061] In this embodiment, the connecting seat 47 is hinged to the swing rod 42, enabling the connecting seat 47 to move freely, which is conducive to the adaptive adjustment of the position and the smooth docking with the charging port during the docking process of the charging bow head and the charging vehicle.

[0062] In a possible embodiment, the connecting seat 47 has a top surface and two lugs arranged on the top surface. The two lugs are respectively arranged on both sides of the swing rod 42, and both lugs are hinged to the swing rod 42. There is a gap between the top surface and the swing rod 42. In this way, the connecting seat 47 can have a larger free swing range. At the same time, under the action of gravity, the connecting seat 47 and the insulator will maintain a vertically downward state, which is conducive to the smooth docking of the electrode on the insulator 43 of the connecting seat 47 and the charging port on the charging vehicle during the downward movement of the adaptive charging bow head 4.

[0063] In a possible implementation, the adaptive pantograph head 4 further includes a pressure sensor 48, the pressure sensor 48 is connected to the connection seat 47, and the insulator 43 is connected to the pressure sensor 48.

[0064] In this implementation, by setting the pressure sensor 48 on the adaptive pantograph head 4. When the pantograph head starts to make contact with the charging vehicle end, if the pressure value detected by the pressure sensor 48 is less than the preset value, it indicates that the contact between the pantograph head 4 and the replacement vehicle is not fully and safely contacted, which is likely to cause an arc during the charging process. Therefore, it is necessary to control the pantograph head 4 to move further towards the charging vehicle. As the pantograph head 4 moves, the pressure detected by the pressure sensor 48 increases. When the detected pressure is greater than the preset value, it indicates that the full contact between the pantograph and the charging vehicle is completed, and then steps such as the power-on protocol handshake between the pantograph head 4 and the charging vehicle can be implemented.

[0065] In a possible implementation, the connection seat 47 has a threaded groove, the insulator 43 is provided with a threaded groove, the pressure sensor 48 has a sensor body and two stud bolts respectively arranged at both ends of the sensor body, and the two stud bolts are respectively threadedly connected to the two threaded grooves.

[0066] One end of the insulator 43 facing away from the connection seat 47 is provided with a connection hole, and the electrode is fixedly connected to the connection hole through a fastener.

[0070] The charging device of the present application has a swing frame, which can be folded onto the planar frame 7 after charging is completed to form a larger passing area at the bottom of the planar frame 7 to avoid passing vehicles.

[0071] In a possible implementation, a fourth motor 61 is provided on the translation seat 6, and the fourth motor 61 is in transmission connection with the swing frame to drive the swing frame to swing. The swing angle of the swing frame can be controlled by controlling the rotation angle of the fourth motor 61.

[0073] In this embodiment, the direction of power transmission of the fourth motor 61 is changed by means of a turbine and worm gear transmission mechanism. At the same time, the turbine and the worm gear have a self-locking effect. When the fourth motor 61 drives the swing frame to a certain angle and no longer drives, or when the power is suddenly cut off, the swing frame will not fall due to the self-locking principle of the turbine and the worm gear, but will maintain the swing angle unchanged.

[0074] In one possible embodiment, see Figure 1 As shown, the swing frame has two connecting walls 91, and the two connecting walls 91 are respectively connected to the two ends of the worm.

[0077] In this embodiment, the second translation drive member 2 is located higher, see Figure 4As shown, after the swing frame is folded, it is parallel to the second translation driving member 2, and the second translation driving member 2 serves to avoid the pantograph head 4. Optionally, the charging device includes a guide rail 5, the guide rail 5 is slidably connected to the planar frame 7, a fitting frame is provided on the guide rail 5, and a lead screw nut is provided on the fitting frame.

The pantograph head 4 has a plurality of insulators 43. The swing frame has a folded state, in which the swing frame is parallel to the planar frame 7, and the insulators are located on both sides of the second lead screw 22.

[0078] In a possible implementation, the swing frame includes a connecting frame 9 and a third translation driving member 3. The connecting frame 9 is swingably connected to the translation seat 6.

The third motor 31 is in transmission connection with the third lead screw 32 to drive the third lead screw 32 to rotate to drive the translation frame 33 to translate.

[0080] See Figure 3 and Figure 5 As shown, the third translation driving member 3 further includes a guide frame 8, the guide frame 8 is fixedly connected to the connecting frame 9, the guide frame 8 has a bottom end beam 83 and a plurality of guide beams 80, the guide beams 80 are parallel to the third lead screw 32, the bottom end beam 83 is connected to each of the guide beams 80, and the end of the third lead screw 32 is rotatably connected to the bottom end beam 83. For example, a third lead screw seat 82 is provided on the bottom end beam 83, and the end of the third lead screw 32 is rotatably connected to the third lead screw seat 82.

[0081] See Figure 1 and Figure 5As shown in the figure, the translation frame 33 has a mating beam 332 and a plurality of translation beams 330.

During the rotation of the third lead screw 32, the translation frame 33 can be driven to translate along the third lead screw 32, while the guiding frame 8 remains in place.

[0082] In a possible implementation, in the circumferential direction of the third lead screw 32, each of the translation beams 330 and the guiding beam 80 is arranged in a staggered manner.

[0083] In this implementation, the translation beam 330 and the guiding beam 80 are arranged in a staggered manner without interfering with each other. The whole structure is light, which is beneficial to reducing consumables, and the internal structure is clearly visible from the outside, facilitating inspection and maintenance operations.

[0084] In a possible implementation, a limiting block 81 is provided on the bottom end beam 83. The limiting block 81 has a limiting sliding groove. A convex rail 331 is provided on the translation beam 330. The convex rail 331 is slidably arranged through the limiting sliding groove.

[0085] The guiding frame 8 does not perform telescopic movement. The design of the limiting block 81 plays a role in limiting the translation frame 33, preventing the translation frame 33 from rotating, so that the translation frame 33 can only translate along the lead screw.

[0088] A plurality of connection holes can be provided on the connecting plate. Fasteners pass through the connection holes and are connected to the limiting block 81.

[0089] In a possible implementation, the swing frame further includes a bottom frame 10 and a fifth motor 101. The bottom frame 10 is connected to the translation frame 33. The fifth motor 101 is connected to the bottom frame 10. The fifth motor 101 has an output shaft, and the charging bow head 4 is connected to the output shaft. In this implementation, the design of the bottom frame 10 facilitates the installation of the fifth motor 101. The fifth motor 101 can rotationally adjust the angle of the charging bow head 4. When the charging vehicle is parked at a position that is tilted left and right relative to the standard position, there is an angular deviation between the charging bow head 4 and the charging port on the charging vehicle, making it impossible to achieve accurate alignment. In response to this situation, the fifth motor 101 can rotate the charging bow head 4 so that the charging bow head 4 rotates to match the left and right tilt angle of the charging vehicle, so that the charging bow head 4 can have the same angle as the charging port on the charging vehicle, ensuring the smooth docking of the charging bow head 4 and the charging port.

The third translation driving member 3 is drivingly connected to the charging bow head 4 to drive the charging bow head 4 to translate in the third direction.

The first motor 11 is disposed on the guide rail 5, and the first motor 11 and the first lead screw 12 are in transmission connection to drive the first lead screw 12 to rotate and drive the translation seat 6 to translate.

One end of the first lead screw 12 is in transmission connection with the first motor 11, and the other end of the first lead screw 12 is rotatably connected to the first lead screw seat 13. It should be noted that two first lead screw seats 13 can be provided, and the two first lead screw seats 13 are respectively disposed on the two movable seats 52. The first lead screw 12 is located between the two rail bars 51 and is parallel to the two rail bars. The first translation driving member 1 and the guide rail 5 are integrally arranged, with a compact structure and space saving.

[0099] In a possible implementation, the planar frame 7 has two second frame edges 72, the two second frame edges 72 are arranged at intervals in sequence in the second direction, and the second frame edges 72 are respectively vertically connected to the two first frame edges 71. The second translation driving member 2 is arranged on the second frame edge 72. In this implementation, the two first frame edges 71 and the two second frame edges 72 enclose a rectangular or square frame.

[0100] In a possible implementation, the second translation driving member 2 includes a second motor 21 and a second lead screw 22.

The second motor 21 is connected to the second frame edge 72, the second lead screw 22 passes through the lead screw nut, and the second lead screw 22 is in transmission connection with the second motor 21.

[0101] In this implementation, the second translation driving member 2 also adopts a lead screw drive, and the displacement of the translation seat 6 in the second direction can be accurately controlled by controlling the rotation angle of the second motor 21.

[0102] In a possible implementation manner, the charging device includes two mounting seats 24, the two mounting seats 24 are respectively arranged on the two second frame edges 72, the second motor 21 is arranged on one of the mounting seats 24, and a second lead screw seat 23 is arranged on the other mounting seat 24.

Among them, second lead screw seats 23 can be arranged on both of the two second frame edges 72, and the second lead screw is rotatably supported on the two second lead screw seats 23.

[0103] In this implementation, the two mounting seats 24 support the second motor 21 and the second lead screw seat 23, avoiding interference between the second lead screw 22 and the translation seat 6.

The third motor 31 is in transmission connection with the third lead screw 32, driving the third lead screw 32 to rotate to drive the translation frame 33 to translate. In this implementation, the third lead screw 32 can be perpendicular to the planar frame 7, or the third lead screw 32 can have different angles with the planar frame 7.

[0105] In a possible implementation, the translation base 6 is connected with a guiding frame 8. A limiting block 81 is arranged on the guiding frame 8, and the limiting block 81 has a limiting sliding groove. A convex rail 331 is arranged on the translation frame 33. The convex rail 331 extends along the length direction of the translation frame 33, and the convex rail 331 is slidably arranged through the limiting sliding groove. The guiding frame 8 does not perform telescopic movement. The design of the limiting block 81 limits the translation frame 33 and prevents the translation frame 33 from performing rotational movement, so that the translation frame 33 can only perform telescopic movement along the lead screw. Wherein, a third lead screw seat 82 is fixedly arranged at the end of the guiding frame 8, and the end of the third lead screw is rotatably connected to the third lead screw seat 82.

The third translation driving member 3 can drive the pantograph head 4 to move in a direction perpendicular to the plane frame 7. When the charging vehicle travels to a certain area range at the bottom of the charging device of the present application, first, the first translation driving member 1 and the second translation driving member 2 can drive the translation base 6 to move, so that the pantograph head 4 is aligned with the charging port on the charging vehicle. Then, as shown in Figure 2 shown, the third translation driving member 3 drives the pantograph head 4 to move downward, so that the pantograph head 4 is connected with the charging port, thereby charging the charging vehicle.

[0107] Embodiment Four

[0108] As shown in Figures 1 to 6 shown, the embodiment of the present application provides an illustration of the charging method for four pairs of charging devices. The charging device has a position detection device. The charging method includes:

[0109] When the charging vehicle travels to the charging area;

[0110] The position detection device detects the position information of the charging port on the charging vehicle;

[0111] The charging device adjusts the position of the pantograph head according to the position information, so that the position of the pantograph head is aligned with the position of the charging port on the charging vehicle. For example, the charging device first controls the first translation driving member and the second translation driving member to drive the translation base to move, so that the translation base is directly above the charging port, that is, the position of the pantograph head is vertically aligned with the position of the charging port on the charging vehicle. Then, the charging device controls the third translation driving member to drive the pantograph head to move downward until the pantograph head and the charging port are successfully docked.

[0112] The position detection device is arranged on any one of the plane frame, the translation base and the pantograph head.

[0113] The position detection device may include an image acquisition module (such as a camera). The position detection device obtains the position information of the charging port by acquiring images of the auxiliary identification of the charging port on the charging vehicle. The charging port and the auxiliary identification of the charging port are arranged on the top of the charging vehicle. The charging device may use image recognition and position deviation recognition algorithms to determine the position of the charging port. For example, sliding search and pixel ratio calculation may be used. The auxiliary identification of the charging port on the vehicle roof may be a white or pure black paper tape or paint, or a white LED, etc.

[0114] In a possible implementation, the multi-dimensional translation mechanism includes: a first translation driving member, a second translation driving member, and a third translation driving member. The first translation driving member is used to drive the charging bow head to translate in a first direction, the second translation driving member is used to drive the charging bow head to translate in a second direction, and the third translation driving member is used to drive the charging bow head to translate in a third direction.

[0115] The position information includes the first direction coordinate, the second direction coordinate, and the third direction coordinate of the charging port;

[0116] The multi-dimensional shifting mechanism controls the translation amounts of the first translation driving member, the second translation driving member, and the third translation driving member respectively according to the first direction coordinate, the second direction coordinate, and the third direction coordinate.

[0117] For safety reasons, the position detection device of the charging device in this application can use two cameras for measurement. One camera is installed on the translation seat, and the other is installed at the bottom end of the third translation driving member, that is, it can be set on the bottom frame or at the bottom of the translation frame. By setting two cameras for measurement, the position of the charging port can be known more accurately, ensuring that the charging device accurately executes the docking task of the charging bow head and the charging port.

[0118] During the process of the charging bow head contacting (docking) with the charging vehicle, the charging device obtains the pressure value detected by the pressure sensor in real time. If the pressure value is less than the set value, it is determined that the charging bow head and the replacement vehicle are not in full contact, and the charging device controls the charging bow head to approach the replacement vehicle (such as controlling the third translation driving member to drive the charging bow head to move up and down) until the pressure value detected by the pressure sensor is not less than the set value.

[0119] During the process of the charging bow head docking with the charging port on the charging vehicle to charge the charging vehicle, the charging device obtains the pressure value detected by the pressure sensor. If the pressure value is less than the set value, it is determined that the charging bow head and the replacement vehicle are separated, and the charging device controls the execution of the protection program. The protection program includes any one or both of controlling power off and controlling the recovery of the charging bow head (controlled by the third translation driving member)
