Description

Technical Field

[0001] This application relates to the field of new energy charging technology, and in particular to a charging alignment device. Background Technology

[0002] The robust growth of new energy vehicles has spurred a surge in charging demand. The supply of traditional charging stations struggles to keep pace with vehicle growth, resulting in charging pain points such as a lack of charging spaces in traditional parking lots, uneven distribution of charging stations, and long waiting times. A current technology separates the charging gun from the charging station. In this system, the charging station is fixed in the parking lot, while the charging gun is mounted on a vehicle carrier. After parking their vehicles on the carrier and inserting the charging gun into the charging port, a transport device moves the carrier to the charging spot. A camera on an alignment mechanism automatically identifies and corrects the QR code on the carrier, facilitating connection between the female connector on the carrier and the charging plug. However, this solution often suffers from errors in QR code recognition, making the alignment mechanism prone to malfunctions. Utility Model Content

Under the guidance of the guide cylinder, the charging plug and the charging female socket achieve precise docking. This application completely eliminates the dependence on camera recognition of QR codes, first achieving coarse alignment through the horizontal movement detection switch, and then achieving fine alignment through the mechanical cooperation of the guide cone and the guide cylinder.

[0035] The robust growth of China's new energy vehicle market has spurred a surge in charging demand. The supply of traditional charging stations struggles to keep pace with vehicle growth, resulting in charging pain points such as a lack of charging spaces in traditional parking lots, uneven distribution of charging stations, and long waiting times. Existing technology proposes a method that separates the charging gun from the charging station. In this method, the charging station is fixed in the parking lot, while the charging gun is mounted on a vehicle carrier. After the vehicle owner parks on the carrier and inserts the charging gun into the vehicle's charging port, a transport device moves the carrier to the charging spot. A camera mounted on an alignment mechanism automatically identifies and corrects the QR code on the carrier, facilitating connection between the female connector on the carrier and the charging plug. However, this solution often suffers from errors in QR code recognition, making the alignment mechanism prone to malfunctions.

[0036] Reference Figures 1 to 9 This application provides a charging alignment device that achieves precise docking between the charging plug 100 and the charging socket 400 through the mechanical cooperation between the guide cone 320 and the guide cylinder 340 and the sensing of the transverse detection switch 350.

[0037] Example 1

[0038] Reference Figures 1 to 5 , Figure 8 The charging alignment device in this embodiment includes a charging plug 100, a moving module 200, and an alignment module 300. The moving module 200 adopts a dual-axis linear motion structure, including a first linear guide rail 210, a first slide 220, a first drive component 230, a second linear guide rail 240, a second slide 250, and a second drive component 260. The first linear guide rail 210 extends along a first direction. The first slide 220 is slidably mounted on the first linear guide rail 210 via a linear bearing. The first drive component 230 adopts a stepper motor and ball screw transmission method. The stepper motor is installed at one end of the first linear guide rail 210, and the ball screw is threadedly connected to the first slide 220. The forward and reverse rotation of the stepper motor drives the first slide 220 to reciprocate along the first linear guide rail 210 in the first direction.

[0039] The second linear guide 240 is vertically fixed to the upper surface of the first slide 220, forming a perpendicular spatial arrangement with the first linear guide 210. The second slide 250 is slidably mounted on the second linear guide 240 via linear bearings. The second drive component 260 also employs a stepper motor and ball screw transmission method. The stepper motor is installed at one end of the second linear guide 240, and the ball screw is threadedly connected to the second slide 250. The forward and reverse rotation of the stepper motor drives the second slide 250 to reciprocate in the second direction on the second linear guide 240. This dual-axis linear motion structure enables the alignment module 300 mounted on the second slide 250 to move precisely in both the first and second directions, achieving precise positioning in a two-dimensional plane.

[0040] The first direction in this embodiment is Figure 1 The left and right directions are shown, and the second direction is... Figure 1 The front and back directions are shown.

[0041] The alignment module 300 is mounted on the second slide 250. The alignment module 300 includes a mounting base 310, a guide cone 320, a guide cone fixing plate 330, a guide cylinder 340, and a transverse movement detection switch 350. The mounting base 310 is fixed to the upper surface of the second slide 250 by bolts. The charging plug 100 is mounted in the center of the guide cone fixing plate 330, using a standard charging interface with multiple charging contact terminals. The guide cones 320 are located on the guide cone fixing plate 330 and distributed on both sides of the charging plug 100. Each guide cone 320 has a conical structure, made of stainless steel, and its surface is polished to reduce frictional resistance. The guide cones 320 are connected to the guide cone fixing plate 330 via connecting rods 321. The connecting rods 321 are cylindrical stainless steel rods and are vertically fixed to the guide cone fixing plate 330. The guide cones 320 and connecting rods 321 are coaxially arranged, with the axis of the guide cone 320 coinciding with the axis of the connecting rod 321.

[0042] The guide cone 320 extends along the insertion / removal direction of the charging plug 100 and the charging socket 400. Along this direction, the end of the guide cone 320 extends beyond the end face of the charging plug 100 by a certain distance; specifically, the top of the guide cone 320 extends 15-25 mm beyond the end face of the charging plug 100. Guide cylinders 340 are used on both sides of the charging socket 400. The guide cylinders 340 have a cylindrical structure, and their inner diameter is larger than the outer diameter of the guide cone 320, with an appropriate clearance between them. The gap ensures that the guide cone 320 can be smoothly inserted into the guide cylinder 340 while also ensuring a good guiding effect. Along the insertion and removal direction of the charging plug 100 and the charging socket 400, the side of the guide cylinder 340 facing the guide cone 320 extends beyond the end face of the charging socket 400 by a certain distance. Specifically, the side of the guide cylinder 340 facing the guide cone 320 extends beyond the end face of the charging socket 400 by 15-25 mm. This design ensures that the guide cone 320 can first contact the guide cylinder 340 during the alignment process, playing a preliminary guiding role.

[0043] The transverse movement detection switch 350 is located on one side of the mounting base 310. It is a diffuse reflection photoelectric switch with high-precision detection capability and good anti-interference performance. The transverse movement detection switch 350 is fixed to the side of the mounting base 310 by a bracket, with the detection surface facing the charging female connector 400. The transverse movement detection switch 350 is connected to the controller of the first drive component 230 via a signal line. When the moving module 200 drives the alignment module 300 to move until the transverse movement detection switch 350 senses the alignment detection point 500, the guide cone 320 aligns with the guide cylinder 340.

[0044] During operation, the moving module 200 first moves the alignment module 300 along the first direction, while the horizontal movement detection switch 350 continuously monitors the alignment detection point 500 on the side of the charging female connector 400. When the horizontal movement detection switch 350 senses the alignment detection point 500, it indicates that the alignment module 300 has moved to the correct horizontal position. At this time, the guide cone 320 and the guide cylinder 340 are initially aligned in the horizontal direction. Subsequently, the moving module 200 moves the alignment module 300 along the second direction, and the guide cone 320 gradually approaches and inserts into the guide cylinder 340. Under the guidance of the guide cylinder 340, the charging plug 100 and the charging female connector 400 achieve precise docking.

[0045] This device is actually used in a charging scenario for a vehicle carrier. Specifically, a storage box is installed on the side of the vehicle carrier, and a charging gun is placed inside the storage box. The charging socket 400 of the charging gun is located on the side of the storage box, and a rectangular through hole is provided on the side of the charging socket 400. This rectangular through hole is the alignment detection point 500. During the process of the first driving component 230 driving the first slide 220 to move along the first direction, the lateral movement detection switch 350 will continuously receive the blocking signal from the storage box. When the lateral movement detection switch 350 moves to the position of the rectangular through hole, it will lose the blocking signal. At this time, the lateral movement detection switch 350 will stop. When 0 is triggered, the horizontal movement detection switch 350 sends a signal to the controller of the first drive component 230. At this time, the first drive component 230 drives the first slide 220 to continue moving a predetermined distance and then stops. At this time, the guide cone 320 and the guide cylinder 340 of the alignment mechanism complete the initial positioning. Then, the second drive component 260 drives the second slide 250 to move along the second direction, so that the guide cone 320 and the guide cylinder 340 cooperate to achieve mechanical precision alignment. The second drive component 260 continues to drive, so that the charging plug 100 and the charging socket 400 can be precisely docked.

[0046] Example 2

[0047] In this embodiment, the movable module 200 also includes a first linear guide rail 210, a first slide 220, a first drive component 230, a second linear guide rail 240, a second slide 250, and a second drive component 260. However, the first linear guide rail 210 and the second linear guide rail 240 do not intersect perpendicularly, but are arranged at a 60-degree angle. This oblique design has better adaptability in certain specific installation environments, especially in space-constrained situations, where it can better utilize limited installation space.

[0048] The first drive component 230 employs a servo motor in conjunction with a rack and pinion transmission mechanism. The servo motor offers higher control precision and response speed. The gear is fixed to the output shaft of the servo motor, and the rack is fixedly connected to the first slide 220. Precise movement of the first slide 220 is achieved through the meshing transmission of the gear and rack. The second drive component 260 uses a linear motor drive. The stator of the linear motor is fixed to the second linear guide rail 240, and the mover is connected to the second slide 250. The second slide 250 is directly driven to move through electromagnetic principles, offering advantages such as fast response speed and high positioning accuracy.

[0049] Example 3

[0050] Reference Figure 8In this embodiment, a transverse movement device 360 ​​is provided between the guide cone fixing plate 330 and the mounting base 310. The transverse movement device 360 ​​includes a slide rail 361 and a slider 362. The slide rail 361 is a linear guide rail, fixed on the mounting base 310, and extends along the first direction. The slider 362 is slidably mounted on the slide rail 361 through a linear bearing, enabling smooth sliding movement on the slide rail 361. The slider 362 is connected to the guide cone fixing plate 330. The transverse movement device 360 ​​allows the guide cone fixing plate 330 to be finely adjusted in the first direction, further improving the alignment accuracy. When the moving module 200 drives the alignment module 300 to the approximate position, during the engagement of the guide cone 320 and the guide cylinder 340, the slider 362 of the transverse movement device 360 ​​can be finely adjusted along the first direction to ensure perfect alignment between the guide cone 320 and the guide cylinder 340.

[0051] Example 4

[0052] Reference Figures 6-8 In this embodiment, the charging plug 100 is provided with four rectangular arrayed connectors 110. Each connector 110 has a first through hole, which is circular. A first buffer structure 120 is provided between each connector 110 and the guide cone fixing plate 330. The first buffer structure 120 includes a first guide shaft 121 and a first compression spring 122. One end of the first guide shaft 121 is fixed to the guide cone fixing plate 330, and the other end passes through the first through hole. The diameter of the first through hole is larger than the diameter of the first guide shaft 121. A first guide shaft 121 is designed to move within the first through hole. A first limiting end plate 123 is provided on the end face of the first guide shaft 121 passing through the first through hole. The first limiting end plate 123 has a circular structure and is used to restrict the first guide shaft 121 from disengaging from the first through hole. A first compression spring 122 is sleeved on the first guide shaft 121 and located between the guide cone fixing plate 330 and the connecting seat 110. One end of the first compression spring 122 contacts the guide cone fixing plate 330, and the other end contacts the connecting seat 110. The design of the first buffer structure 120 allows the first compression spring 122 to absorb the impact force during the docking process of the charging plug 100 and the charging female seat 400, protecting the charging plug 100 and the charging female seat 400 from damage.

[0053] Of course, in other embodiments, three or five connectors 110 can be arrayed on the charging plug 100, and three or five first buffer structures 120 are also provided accordingly. It should be noted that when two connectors 110 are provided, the two connectors 110 are respectively provided on both sides of the charging plug 100, rather than on the same side.

[0054] Example 5

[0055] Reference Figure 6 , Figure 7 In this embodiment, four arrayed second buffer structures 370 are provided between the guide cone fixing plate 330 and the slider 362. The second buffer structure 370 includes a second guide shaft 371 and a second compression spring 372, and its structural principle is the same as that of the first buffer structure 120.

[0056] A second through hole is provided on the guide cone fixing plate 330 at the position corresponding to each of the second buffer structures 370. The second through hole is a circular hole. One end of the second guide shaft 371 is connected and fixed to the slider 362, and the other end passes through the corresponding second through hole. The diameter of the second through hole is larger than the shaft diameter of the second guide shaft 371. A second limiting end plate 373 is provided on the end face of the second guide shaft 371 that passes through the second through hole. The second limiting end plate 373 is used to restrict the second guide shaft 371 from disengaging from the second through hole. A second compression spring 372 is sleeved on the second guide shaft 371. One end of the second compression spring 372 is connected to the guide cone fixing plate 330, and the other end is connected to the slider 362. The second buffer structure 370 is provided to further absorb the impact force during the docking process and protect the charging plug 100 and the charging female socket 400 from damage.

[0057] Of course, in other embodiments, the second buffer structure 370 can also be arrayed with 6 or 8 according to actual usage requirements.

[0058] Example 6

[0059] In this embodiment, side plates 311 are provided on both sides of the mounting base 310. The side plates 311 have a rectangular plate structure and are distributed at both ends of the slide rail 361. The forward projection of the slide rail 361 along its length direction is within the range of the side plates 311. Two arrayed third buffer structures 380 are provided between the slider 362 and the side plates 311. The third buffer structure 380 includes a third guide shaft 381 and a third compression spring 382. A third through hole is provided on the side plate 311 corresponding to the position of each third buffer structure 380. One end of the third guide shaft 381 is fixedly connected to the slider 362, and the other end passes through the corresponding third through hole. The diameter of the third through hole is larger than the shaft diameter of the third guide shaft 381. A third limiting end plate 383 is provided on the end face of the third guide shaft 381 that passes through the third through hole. The third limiting end plate 383 is used to prevent the third guide shaft 381 from disengaging from the third through hole. One end of the third compression spring 382 is connected to the slider 362, and the other end is connected to the side plate 311. The third buffer structure 380 is configured to provide additional buffer protection for the slider 362 of the transverse moving device 360. When the slider 362 moves on the slide rail 361, the third buffer structure 380 can absorb the impact force, reduce vibration, and improve the stability and service life of the entire device. In addition, the side plates 311 on both sides of the mounting base 310 also serve to limit the slider 362 and prevent the slider 362 from disengaging from the slide rail 361.

[0061] In this embodiment, position detection switches 331 are provided on both sides of the charging plug 100. The position detection switches 331 are proximity switches, which have the characteristics of high precision and high reliability.

[0062] The positioning detection switch 331 is used to sense the positioning detection points on both sides of the charging female connector 400. When the charging plug 100 approaches the charging female connector 400 and reaches the predetermined position, the positioning detection switch 331 can accurately sense the positioning detection point and transmit the signal to the controller of the second drive component 260. After receiving the signal, the controller immediately stops the operation of the second drive component 260 to ensure that the charging plug 100 stops in the correct position.

[0063] A position detection switch mounting base 332 is installed on the guide cone fixing plate 330. The position detection switch mounting base 332 has an L-shaped structure, with the horizontal part fixed to the top of the guide cone fixing plate 330 and the vertical part used to install the position detection switch 331. The position detection switch 331 is fixed on the vertical part of the position detection switch mounting base 332, with the detection surface facing the charging female socket 400.

[0064] In addition, an alignment detection switch 312 is also provided on the mounting base 310. The alignment detection switch 312 is also a proximity switch. The alignment detection switch 312 is used to sense the alignment detection point 500 on the side of the charging female base 400. Its position is set on the extension line of the line connecting the ends of the two guide cones 320. The alignment detection switch 312 is connected to the controller of the second drive component 260.

[0065] Specifically, the alignment detection switch 312 is fixed to the guide cone fixing plate 330 by a straight rod 313. Along the insertion / removal direction of the charging plug 100 and the charging socket 400, during the process of the second drive component 260 driving the guide cone 320 to insert into the guide cylinder 340, the alignment detection switch 312 corresponds to the alignment detection point 500. In the embodiment of the vehicle carrier plate of this application, during the process of the guide cone 320 inserting into the guide cylinder 340, the alignment detection switch 312 corresponds to a rectangular through hole and therefore will not be blocked. Therefore, during the process of the guide cone 320 inserting into the guide cylinder 340, the alignment detection switch 312 will also enter the rectangular through hole on the storage box. If the alignment detection switch 312 encounters a blocking signal during the process of the guide cone 320 inserting into the guide cylinder 340, it indicates that the guide cone 320 and the guide cylinder 340 are not aligned, and the second drive component 260 will stop driving.

[0066] Example 8

[0067] In this embodiment, a shielding plate 390 is installed on the top of the guide cone fixing plate 330. The shielding plate 390 can cover the top of the guide cone fixing plate 330, the top of the position detection switch 331, and part of the top of the charging plug 100. The shielding plate 390 effectively prevents dust, water droplets, and other impurities from entering the precision components, improving the protection level of the entire device. The shielding plate 390 is fixed to the top of the guide cone fixing plate 330 with bolts, making it easy to install and remove, and facilitating later maintenance.

[0068] Example 9

[0069] In this embodiment, a servo motor is used as the first driving component 230 and the second driving component 260. The servo motor has the advantages of high precision, high response speed and low noise.

[0070] Each of the two servo motors is equipped with an independent controller, which has multiple control modes such as position control, speed control, and torque control.

[0071] This invention completely eliminates the reliance on camera-based QR code recognition. It first achieves coarse alignment through a horizontal movement detection switch 350, and then achieves fine alignment through the mechanical cooperation of the guide cone 320 and guide cylinder 340. Furthermore, throughout the alignment process between the guide cone 320 and guide cylinder 340, an alignment detection switch 312 monitors and senses the alignment, greatly improving the system's reliability and stability. The multi-level buffer structure design makes the entire alignment process smoother, effectively absorbing impact forces and protecting the charging plug 100 and charging socket 400 from damage, extending the equipment's lifespan. The horizontal movement device 360 ​​can adapt to minor changes in the position of the charging socket 400, improving the alignment success rate. The dual-axis moving module 200 design achieves precise positioning in a two-dimensional plane.

[0072] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
