Description

Technical Field

[0001] The present application relates to the technical field of charging devices, and in particular to a foldable charging device. Background Art

[0002] Charging equipment has a charging bow head. Common charging bow heads have limited freedom of movement and cannot perform three-dimensional motion. When charging, the charging cart needs to be precisely positioned at the charging station on the device so that the charging bow head can align with the charging port and charge the cart. This increases the difficulty of driving and places high demands on the driver. Even slightly deviating from the charging station can cause the charging bow head to misalign with the charging port on the cart, resulting in a poor user experience.

[0003] In addition, after the vehicle is charged, it is usually necessary to retract the charging bow head to prevent the charging bow head from colliding with passing vehicles. However, if the charging equipment only adjusts the height of the charging bow head by telescoping it up and down, the charging bow head cannot be raised to the maximum extent due to the limited telescopic control length. When a taller vehicle passes by, there is still a risk of collision and interference.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0064] The foldable charging device of the present application has a swing frame, which can be folded into the plane frame 7 after charging is completed, so as to form a larger passing area at the bottom of the plane frame 7 to avoid passing vehicles.

[0065] In a possible embodiment, a fourth motor 61 is provided on the translation base 6, and the fourth motor 61 is in transmission connection with the swing frame to drive the swing frame to swing.

At the same time, the turbine and 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, due to the self-locking principle of the turbine and worm gear, the swing frame will not fall, but will maintain the swing angle unchanged.

Optionally, the foldable 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 first translation driving member 1 is disposed on the guide rail 5, and the first translation driving member 1 is in transmission connection with the translation seat 6 to drive the translation seat 6 to translate along the guide rail 5. The second translation driving member 2 has a second lead screw 22, the second lead screw 22 is perpendicular to the guide rail 5, and the second lead screw 22 is in threaded connection with the lead screw nut. 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.

[0072] In a possible embodiment, 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 translation driving member 3 is connected to the connecting frame 9, and the pantograph head 4 is connected to the third translation driving member 3.

[0073] The connecting frame 9 has the two connecting walls 91 as described above. The third translation driving member 3 includes a third motor 31, a third lead screw 32, and a translation frame 33. The third motor 31 is disposed on the connecting frame 9, the third lead screw 32 is in threaded connection with the translation frame 33, and the pantograph head 4 is connected to the translation frame 33. 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.

[0074] Refer to 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.

[0075] Refer to Figure 1 and Figure 5As shown, the translation frame 33 has a mating beam 332 and a plurality of translation beams 330. The mating beam 332 is threadedly connected to the third lead screw 32. Each translation beam 330 is connected to the mating beam 332. Each translation beam 330 is parallel to the third lead screw 32. The pantograph head 4 is connected to each translation beam 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.

[0076] 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 are arranged in a staggered manner.

[0077] In this implementation, the translation beams 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.

[0078] 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.

[0079] 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.

[0083] 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.

In this implementation, the design of the bottom frame 10 facilitates the installation of the fifth motor 101. The fifth motor 101 can rotate to 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.

[0085] See Figure 1 and Figure 2 As shown, the embodiments of the present application further elaborate on the charging device in detail. The charging device includes: a charging bow head 4, a planar translation mechanism, and a swing frame. The planar translation mechanism includes a first translation driving member 1 and a second translation driving member 2. The swing frame includes a third translation driving member 3.

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 a third direction. It should be noted that the term "driving connection" in the present application can be a direct connection or an indirect connection.

[0086] Among them, the first direction and the second direction are perpendicular to each other, and the third direction can change the angle according to the swing of the swing frame. The third direction can be perpendicular to the first direction and the second direction respectively.

The guide rails 5 are respectively slidably connected to the two first frame edges 71. The first translation driving member 1 is connected to the guide rails 5.

[0089] In this embodiment, the planar frame 7 is generally rectangular. The two ends of the guide rail 5 are respectively slidably connected to the two first frame edges 71, and the two first frame edges 71 play a role in stably supporting the guide rail 5.

[0090] In a possible embodiment, the first translation driving member 1 includes a first motor 11 and a first lead screw 12. The translation seat 6 has a threaded groove. The first lead screw 12 penetrates through the threaded groove. The first motor 11 is arranged 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.

[0091] In this embodiment, the first translation driving member 1 adopts a lead screw drive, and the displacement of the translation seat 6 in the first direction can be accurately controlled by controlling the rotation angle of the first motor 11.

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.

[0093] In a possible implementation, the planar frame 7 has two second frame edges 72 which are arranged at intervals in sequence in the second direction, and the two second frame edges 72 are respectively and perpendicularly 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.

[0094] In a possible implementation, the second translation driving member 2 includes a second motor 21 and a second lead screw 22. A mating frame is arranged on the guide rail 5, and a lead screw nut is arranged on the mating frame. 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.

[0095] 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.

[0096] In a possible implementation manner, the charging device includes two mounting seats 24 which 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. One end of the second lead screw 22 is in transmission connection with the second motor 21, and the other end of the second lead screw 22 is rotatably connected to the second lead screw seat 23. 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.

[0097] 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 spatial distance between the second lead screw 22 and the guide rail 5 needs to be sufficient for the translation seat 6 to translate through.

[0098] In a possible implementation, the third translation driving member 3 includes a third motor 31, a third lead screw 32 and a translation frame 33. The charging bow head 4 is connected to the translation frame 33. The third motor 31 is connected to the translation seat 6, and the third lead screw 32 is in threaded connection with the translation frame 33. 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 a different included angle with the planar frame 7.

[0099] In a possible embodiment, the translation seat 6 is connected to a guide frame 8, and a limit block 81 is provided on the guide frame 8, and the limit block 81 has a limit slide groove. A convex rail 331 is provided on the translation frame 33, and the convex rail 331 extends along the length direction of the translation frame 33. The convex rail 331 can slide through the limit slide groove. The guide frame 8 will not perform telescopic movement. The design of the limit block 81 serves to limit the translation frame 33, preventing the translation frame 33 from rotating, so that the translation frame 33 can only telescopic movement along the lead screw. Among them, a third lead screw seat 82 is also fixedly provided at the end of the guide frame 8, and the end of the third lead screw is rotatably connected to the third lead screw seat 82.

[0100] In the embodiment of the present application, the first translation drive 1 and the second translation drive 2 drive the translation seat 6 to move within the plane of the plane frame 7. The third translation drive 3 can drive the charging bow 4 to move in a direction perpendicular to the plane frame 7. When the charging vehicle moves to a certain area at the bottom of the charging device of the present application, the first translation drive 1 and the second translation drive 2 can first drive the translation seat 6 to move so that the charging bow 4 is aligned with the charging port on the charging vehicle, and then, see Figure 2 As shown, the third translation drive member 3 drives the charging bow head 4 to move downward, so that the charging bow head 4 is connected to the charging port, thereby charging the charging vehicle.

[0101] Example 3

[0102] See also Figure 5 and Figure 6 As shown, the present embodiment provides a detailed description of a charging bow head for a charging device. This charging bow head can be an adaptive charging bow head 4, comprising: a main beam 41, two side arm assemblies, multiple stoppers 44, and an elastic member 45.

The two swing arms 42 extend to either side of the main beam 41 and are connected to insulators 43. Each stopper 44 is connected to the main beam 41 and engages with each swing arm 42 to limit the swing angle of each swing arm 42. An elastic member 45 is connected to the main beam 41 and abuts against the side of each swing arm 42 facing away from the insulator 43, causing each swing arm 42 to tilt toward the insulator.

[0103] The adaptive charging bow head 4 of the present application can, when the charging vehicle stops 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 charging bow head 4 approaching and connecting to the charging vehicle, the electrode on the insulator 43 on one swing rod 42 in the side arm assembly first contacts one interface of the charging vehicle, and the other swing rod 42 of the side arm assembly will tilt downward 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. The adaptive charging bow head 4 of the present application can, when the charging vehicle stops on an uneven road surface or the charging port is tilted due to inconsistent tire pressures on both sides of the charging vehicle, the charging bow head 4 can automatically tilt by a corresponding angle, so that the electrodes on each insulator 43 on the charging bow head 4 can be stably connected or contacted with the corresponding interfaces on the charging port respectively, and the charging circuit is not easily disconnected, and the charging vehicle can be stably charged.

[0104] In a possible implementation, as shown in Figure 5 shown, the limiting member 44 includes a first limiting beam 441 and a second limiting beam 442, and the first limiting beam 441 and the second limiting beam 442 are respectively located on both sides of the corresponding swing rod 42 along the swinging direction.

[0105] In this implementation, the two limiting beams can limit the swinging angle of the swing rod 42, so that the swing rod 42 moves within an effective range. For example, the swing rod 42 can adjust the tilting angle within the range of ±2 to 3°, and this angle is relatively small. When the tilting 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 limit position, the limiting beam can contact the swing rod 42, so that the electrode on the insulator 43 on the swing rod 42 can be stably docked with the charging port on the battery swapping vehicle and is not easily disconnected.

[0106] In a possible implementation, first upper inclined surfaces 421 and first lower inclined surfaces 422 are respectively provided on both end faces of the swing rod 42 along the swinging direction. A second upper inclined surface is provided on the surface of the first limiting beam 441 facing the swing rod 42, and second lower inclined surfaces are provided on the surfaces of the second limiting beam 442 facing the swing rod 42. In the state where the swing rod 42 swings to the first limit position, the first upper inclined surface 421 and the second upper inclined surface are in contact with each other. In the state where the swing rod 42 swings to the second limit position, the second lower inclined surface and the second lower inclined surface are in contact with each other.

[0107] In this implementation, when the swing rod 42 swings to the limit position, the inclined surfaces on the swing rod 42 and the inclined surfaces on the limiting beam can be smoothly in contact with each other. This contact between surfaces has good stability and reduces the wear between the swing rod 42 and the limiting beam.

[0108] In a possible implementation, as shown in Figure 5As 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 circular ring 46 is sleeved on the main beam 41, and extension rods are provided on both sides of the circular ring 46, which are connected to the connecting beam 443. The circular ring 46 is connected to the main beam 41, and the circular ring 46 and the main beam 41 are limited in position and cannot rotate relative to the main beam 41. An extension rod is provided on each side of the circular ring 46 to connect the connecting beams 443 on the position-limiting member 44 on both sides.

[0109] In a possible embodiment, 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 press against the end of the corresponding rocker 42 away from the insulator 43.

[0110] 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 force to the two rocker arms 42 respectively, so that the two rocker arms 42 are respectively fitted to the second limiting beams 442 on the corresponding limiting parts 44, so that under normal conditions, the two rocker arms 42 are stably supported on the second limiting beams 442 of the limiting parts 44. When the top of the battery swapping vehicle is tilted, when the adaptive charging bow head 4 and the battery swapping vehicle are docked for charging, the two rocker arms 42 can automatically adjust the tilt angle. When the tilt angle of the rocker arm 42 is greater, the elastic force of the torsion arm 452 is greater, so that the electrode on the insulator 43 on the rocker arm 42 can be more stably docked with the charging port and will not be easily disconnected.

[0111] In one possible embodiment, see Figure 5 As shown, the main beam 41 has a main shaft, a limiting section, an end shaft and an anti-slip 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-slip sleeve 411 is fixedly sleeved on the end shaft, the cross section of the limiting section can be non-circular, such as polygonal, the center hole of the annulus can also be a polygonal hole, the annulus is sleeved on the limiting section and will not rotate around the limiting section, the diameter of the end shaft is smaller than the limiting section and the main shaft, the anti-slip sleeve 411 is sleeved on the end of the end shaft, the ends of two rocking rods 42 are rotatably sleeved on the end shaft, the rocking rod 42 is limited between the limiting section and the anti-slip sleeve 411, and the spiral portion 451 is sleeved on the anti-slip sleeve 411. Wherein, the anti-slip sleeve 411 can be threadedly connected to the end shaft.

[0112] In a possible implementation, 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 rocker 42 .

[0113] 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 self - adapting the position adjustment during the docking process of the pantograph head and the charging vehicle and smoothly docking with the charging port.

[0114] In a possible embodiment, the connecting seat 47 has a top surface and two lugs provided 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 relatively large 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 electrodes on the insulator 43 of the connecting seat 47 smoothly docking with the charging port on the charging vehicle during the downward movement of the self - adapting pantograph head 4.

[0115] In a possible embodiment, the self - adapting pantograph head 4 further includes a pressure sensor 48. The pressure sensor 48 is connected to the connecting seat 47, and the insulator 43 is connected to the pressure sensor 48.

[0116] In this embodiment, by setting the pressure sensor 48 on the self - adapting pantograph head 4. When the pantograph head starts to come into contact with the charging vehicle end for control, 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 does not reach a safe and sufficient contact, 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 pantograph and the charging vehicle have completed sufficient contact, and then steps such as the power - on protocol handshake between the pantograph head 4 and the charging vehicle can be implemented.

[0117] In a possible embodiment, the connecting 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 studs respectively arranged at both ends of the sensor body. The two studs are respectively threadedly connected to the two threaded grooves.

[0118] One end of the insulator 43 facing away from the connecting seat 47 is provided with a connection hole, and the electrode is fixedly connected to the connection hole through a fastener.

[0119] Embodiment Four

[0120] See Figures 1 to 6 As shown, the embodiments of the present application provide an explanation of the charging method for four pairs of charging devices. The charging device has a position detection device, and the charging method includes:

[0121] When the charging vehicle travels to the charging area;

[0122] The position detection device detects the position information of the charging port on the charging vehicle;

[0123] The charging device adjusts the position of the charging bow head according to the position information, so that the position of the charging bow 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 seat to move, so that the translation seat is directly above the charging port, that is, the position of the charging bow 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 charging bow head to move downward until the charging bow head and the charging port are successfully docked.

[0124] The position detection device is arranged on any one of the planar frame, the translation seat and the charging bow head.

[0125] 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 the image of the auxiliary mark of the charging port on the charging vehicle. A charging port and an auxiliary mark of the charging port are arranged on the top of the charging vehicle. The charging device can use image recognition and position deviation recognition algorithms to determine the position of the charging port. For example, sliding search and pixel ratio calculation can be used. The auxiliary mark of the charging port on the roof can be a white or pure black paper tape or paint, or a white LED, etc.

[0126] 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 along a first direction, the second translation driving member is used to drive the charging bow head to translate along a second direction, and the third translation driving member is used to drive the charging bow head to translate along a third direction.

[0127] The position information includes the first direction coordinate, the second direction coordinate and the third direction coordinate of the charging port;

[0128] 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.

[0129] For safety reasons, the position detection device of the charging device in this application can be measured by two cameras. 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 arranged 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.

[0130] During the process of the pantograph head contacting (docking) with the charging vehicle, the charging device continuously obtains the pressure value detected by the pressure sensor. If the pressure value is less than the set value, it is determined that the pantograph head and the replacement vehicle are not in full contact, and the charging device controls the pantograph head to approach the replacement vehicle (for example, controls the third translation drive to drive the pantograph head to move up and down) until the pressure value detected by the pressure sensor is not less than the set value.

[0131] During the process of the pantograph 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 pantograph head and the replacement vehicle are separated, and the charging device controls the execution of a protection program. The protection program includes any one or both of controlling power off and controlling the retraction of the pantograph head (controlled by the third translation drive).

[0132] The above are only the preferred embodiments of the present invention, and there is no any form of limitation to the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes.
