Description

Technical Field

[0001] This invention relates to the field of AGV charging technology, and more particularly to an AGV charging pile. Background Technology

[0002] Most existing charging piles for AGV equipment have their charging connectors fixedly exposed outside the charging pile chassis. Due to long-term exposure to the external environment, the charging connectors are easily affected by external impacts or dust, which can cause corrosion and oxidation. They are also easily damaged or malfunctioned by external objects, which can reduce their service life. Similarly, the charging board that connects the AGV vehicle to the charging head is also exposed to the outside. During the operation of the vehicle, it can be covered by dust and other impurities in the air. When the charging board connects to the connector, the dust can cause poor contact or difficulty in connection, which may lead to charging interruption during the charging process. Meanwhile, existing charging connectors are mostly connected to the charging pile in a fixed manner. Therefore, the overall position and orientation angle of the charging connector are fixed. However, in actual production activities, due to the navigation and positioning errors of AGVs and the flatness of the processing and ground, there will be a certain positional deviation between the charging port at the end of the AGV and the charging head of the charging pile. These angular and positional deviations cannot be solved by the charging connectors and charging piles installed in the existing technology through a fixed connection. Therefore, in view of the problems existing in the above-mentioned prior art, this invention proposes an AGV charging pile to solve such problems. Summary of the Invention

[0005] As a preferred embodiment of the AGV charging pile of the present invention, wherein: a connecting block is provided at one end of the connecting rod that is inserted into the sleeve, a plug shaft is provided at the outer end of the connecting rod, and the plug shaft is inserted downward into the transfer ball; the structure of the second buffer component is exactly the same as that of the first buffer component, and the centers of the first buffer component and the second buffer component coincide, and the overlapping part of the two is fixedly connected to the fixed seat.

[0006] As a preferred embodiment of the AGV charging pile of the present invention, the portion of the transfer ball surrounded by the first buffer component and the second buffer component is a spherical structure, a clearance groove is provided inside the transfer ball, and one end of the charging component is installed in the clearance groove.

[0007] As a preferred embodiment of the AGV charging pile of the present invention, the mounting frame has a semi-circular mounting groove inside, and a side opening with a diameter smaller than that of the transfer ball is opened on the side of the mounting groove. The inner wall of the side opening is attached to the arc-shaped outer wall of the transfer ball, and the outer ends of the mounting frame have arc-shaped chamfers on both sides.

[0008] As a preferred embodiment of the AGV charging pile of the present invention, the pile body has a storage compartment inside, and the compensation unit is located in the storage compartment. Two sets of sealing components are symmetrically arranged on both sides of the storage compartment. The pile body has a telescopic component installed inside, and one end of the telescopic component is fixedly connected to the fixed base.

[0009] As a preferred embodiment of the AGV charging pile of the present invention, the sealing component includes a sealing plate located in the storage compartment, and the sealing plate has a triangular structure. The hypotenuse of the triangular structure abuts against the outer apex of the mounting frame, and a spring is disposed between the sealing plate and the storage compartment.

[0010] As a preferred embodiment of the AGV charging pile of the present invention, the driving component includes a driving shaft inserted into the pile body, a gear sleeved on the driving shaft, a limiting block disposed at the inner end of the driving shaft, the limiting block having a rectangular structure, two sets of spiral grooves spirally wound on the driving shaft, and two sets of balls symmetrically disposed on the inner side of the gear, the inner side of both sets of balls extending into the spiral groove, a limiting groove matching the balls being opened inside the pile body, the balls extending into the limiting groove, and a supporting spring being disposed in the limiting groove.

[0011] As a preferred embodiment of the AGV charging pile of the present invention, the meshing component includes a rack arranged laterally in the pile body, and the rack meshes with a gear, an extension shaft arranged vertically at one end of the rack, and a socket arranged at the top of the extension shaft, and a cleaning component is inserted laterally into the socket. The cleaning component includes a connecting rod inserted laterally into the socket, and the connecting rod extends outward to the outside of the pile body, and a cleaning brush arranged vertically at the outer end of the connecting rod.

[0013] The beneficial effects of the present invention are as follows: by setting the sealing component and the telescopic component to work together, the compensation unit can extend when it needs to be charged and retract into the pile body when it is not working. The sealing component isolates the compensation unit retracted into the pile body from the outside, avoiding the compensation unit being exposed to the outside for a long time, reducing the impact and damage of external factors on the compensation unit, ensuring its safety and extending its service life. By setting up the first buffer component, the second buffer component, and the charging component to work together, it is possible to move and twist in six directions: up, down, left, right, front, and back. This allows the compensation unit to adjust and compensate for the angle and position in six directions. The position error of the AGV equipment during charging can be offset by multi-directional and multi-angle movement adjustment and buffering, thereby ensuring the precise docking of the AGV equipment and the compensation unit and ensuring the charging effect. By setting up a cleaning unit to clean the charging board, when the AGV vehicle docks with the charging pile, the charging board comes into contact with the cleaning unit. The cleaning unit contacts the charging board through two sets of meshing parts. At the same time as contacting the charging board, the two sets of meshing parts move in opposite directions along the surface of the charging board. The meshing parts moving in opposite directions clean the surface of the charging board while moving, so that the charging board is connected to the charging component in a clean state, ensuring the docking and charging effect between the two.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Reference Figures 1 to 6 This invention provides an embodiment of an AGV charging pile, comprising a pile body 1, a compensation unit 2, and a cleaning unit 3. The compensation unit 2 includes a mounting frame 26 disposed within the pile body 1, a fixed seat 21 disposed within the mounting frame 26, a first buffer component 22 disposed on the side of the fixed seat 21, a second buffer component 23 disposed on the side of the fixed seat 21 and perpendicular to the first buffer component 22, a transfer ball 24 partially encircled by the first buffer component 22 and the second buffer component 23, and a charging component 25 disposed on one side of the transfer ball 24. The charging component 25 is the part that directly contacts the charging end of the AGV equipment. The first buffer component 22 and the second buffer component 23 are used to install and fix the transfer ball 24, and both keep the transfer ball 24 in a horizontal angle state at all times. Reference Figure 5The first buffer component 22 includes a sleeve 221 fixedly connected to the fixed base 21, two sets of connecting rods 222 symmetrically inserted at both ends of the sleeve 221, and the sleeve 221 and the two sets of connecting rods 222 are combined into an arc-shaped structure, and a second spring 223 located between the sleeve 221 and the connecting rods 222. The connecting rods 222 can slide and extend within the sleeve 221, while the second spring 223, through its own elastic support and the cooperation of the corresponding connecting rods 222, can keep the transfer ball 24 at a fixed angle, that is, keep the transfer ball 24 and the charging component 25 in a horizontally outward extended state. Reference Figure 7 The cleaning unit 3 includes a drive component 31 inserted into the pile body 1, two sets of engagement components 32 arranged laterally in the pile body 1, with the two sets of engagement components 32 being horizontally offset and parallel, and a cleaning component 33 inserted into each set of engagement components 32, with the outer end of the cleaning component 33 extending to the outside of the pile body 1, and one end of the drive component 31 extending to the outside of the pile body 1 and being on the same vertical line as the outer end of the cleaning component 33. When the AGV is being charged, the two will preferentially contact the AGV body and the charging base plate 4.

[0029] Among them, reference Figure 5 The charging component 25 includes a charging base 251 that is horizontally inserted into the transfer ball 24, a spring 252 disposed between the charging base 251 and the transfer ball 24, and a brush 253 disposed on the outside of the charging base 251. The spring 252, through elastic support, can keep the entire charging component 25 extended to the outside of the transfer ball 24. When the charging component 25 contacts the charging end of the AGV equipment, the spring 252 can achieve horizontal front-to-back position compensation adjustment through its own elastic contraction.

[0030] Furthermore, refer to Figure 5 The sleeve 221 is an internally hollow arc-shaped pipe, and one end of the connecting rod 222 extends into the sleeve 221. At the same time, the sleeve 221 and the connecting rod 222 are concentric, and the intermediate ball 24 is located at the concentric position of the two. The intermediate ball 24 is also concentric with the two, so the intermediate ball 24 will not separate from the two when rotating at any angle.

[0031] Furthermore, refer to Figure 5 A connecting block 224 is provided at one end of the connecting rod 222 that is inserted into the sleeve 221. A shaft 225 is provided at the outer end of the connecting rod 222, and the shaft 225 is inserted downward into the intermediate ball 24. The structure of the connecting block 224 matches the inner diameter of the sleeve 221, and the shaft 225 is rotatably connected to the intermediate ball 24.

[0032] Furthermore, refer to Figure 6The structure of the second buffer component 23 is exactly the same as that of the first buffer component 22, and the centers of the first buffer component 22 and the second buffer component 23 coincide. At the same time, the overlapping part of the two is fixedly connected to the fixed base 21. The second buffer component 23 works in the same way as the first buffer component 22, except that the second buffer component 23 performs vertical swing compensation.

[0033] Furthermore, refer to Figure 5 The portion of the transfer ball 24 surrounded by the first buffer component 22 and the second buffer component 23 is spherical. A clearance groove 241 is provided inside the transfer ball 24, and one end of the charging component 25 is installed in the clearance groove 241. The spherical transfer ball 24 can rotate over a wider range and at a wider angle.

[0034] Among them, reference Figure 4 The mounting bracket 26 has a semi-circular mounting groove 261 inside. The side of the mounting groove 261 has a side opening 262 with a diameter smaller than that of the transfer ball 24. The inner wall of the side opening 262 fits against the arc-shaped outer wall of the transfer ball 24. The outer ends of the mounting bracket 26 have arc-shaped chamfers on both sides. The side opening 262 with a diameter smaller than that of the transfer ball 24 can prevent the transfer ball 24 from falling off. The chamfered outer ends of the mounting bracket 26 make its contact with the sealing component 12 smoother.

[0035] Among them, reference Figure 2 The pile body 1 has a storage compartment 11 inside, and the compensation unit 2 is located inside the storage compartment 11. Two sets of sealing components 12 are symmetrically arranged on both sides of the inside of the storage compartment 11. The storage compartment 11 is used to store the compensation unit 2 and the sealing components 12.

[0036] Among them, reference Figure 2The sealing component 12 includes a sealing plate 121 located inside the storage compartment 11. The sealing plate 121 has a triangular structure, with the hypotenuse of the triangle abutting against the outer apex of the mounting bracket 26. A spring 122 is disposed between the sealing plate 121 and the storage compartment 11. The spring 122, through its elastic support, keeps the hypotenuse of the sealing plate 121 against the outer apex of the mounting bracket 26. Under normal conditions, the two sets of sealing components 12, through their respective springs 122, cause the two sets of sealing plates 121 to close together, thereby completely enclosing and isolating the compensation unit 2 within the storage compartment. Inside the storage compartment 11, to prevent the compensation unit 2 from being exposed to the outside for a long time, when the telescopic component 13 pushes the compensation unit 2 outward as a whole, the top corner of the outer wall of the mounting bracket 26 will push the inclined side of the sealing plate 121. As the compensation unit 2 continues to extend outward, the mounting bracket 26 will cooperate with the inclined side of the sealing plate 121, and finally the sealing plate 121 will squeeze the spring 122 and retract itself into the two sides of the storage compartment 11. When the compensation unit 2 retracts with the telescopic component 13, the spring 122 will return the sealing plate 121 to its original position through elastic rebound, and continue to block the channel of contact between the compensation unit 2 and the outside.

[0037] Among them, reference Figure 2 The pile body 1 is equipped with a telescopic component 13, and one end of the telescopic component 13 is fixedly connected to the fixed seat 21. The telescopic component 13 is a common telescopic structure in the prior art, which can realize the telescopic movement of the compensation unit 2 through actual control.

[0038] In summary, referring to Figure 5 and Figure 6During use, the charging component 25 abuts against the charging end of the AGV equipment. At this time, the charging component 25 is squeezed by the AGV equipment charging end. Through the elastic deformation of spring 252, the charging component 25 adjusts its position horizontally, forward, or backward according to the actual situation. When the AGV equipment charging end is tilted due to the unevenness of the ground, the charging end tilts horizontally to the left. Due to the contact between the AGV equipment charging end and the charging component 25, the pressure on the left side of the AGV equipment charging end is greater than that on the charging component 25. This causes the charging component 25 to drive the transfer ball 24 to deflect horizontally to the left. At this time, the connecting rod 222 on the left side of the transfer ball 24 compresses its corresponding spring 223, causing the left connecting rod 222 to retract into the sleeve 221, while the right connecting rod 222 extends outward from the sleeve 221. The transfer ball 24 as a whole tilts to the left relative to the matching angle of the AGV equipment charging end, thus causing the charging component 25 and the AGV equipment charging end to... The contact surface of the charging end is converted into a parallel and fitted posture to ensure precise docking between the two. Conversely, when the charging end of the AGV equipment tilts to the right, the right end of the first buffer component 22 will be driven to tilt to the right under its squeezing force, thereby keeping the charging component 25 and the charging end of the AGV equipment in a parallel posture to ensure accurate docking. The second buffer component 23 moves in the same way as the first buffer component 22, and can adjust and compensate for the vertical front and rear angle positions according to the actual angle of the charging end of the AGV equipment. Thus, by setting the first buffer component 22, the second buffer component 23 and the charging component 25 to work together, it is possible to achieve movement and twisting in six angles: up, down, left, right, front and back. This allows the compensation unit 2 to adjust and compensate for the angle and position in six directions, so that the position error of the AGV equipment during charging can be offset by multi-directional and multi-angle movement adjustment and buffering, thereby ensuring precise docking between the AGV equipment and the compensation unit 2 and ensuring the charging effect.

[0039] Furthermore, refer to Figure 8The driving component 31 includes a drive shaft 311 inserted into the pile body 1, a gear 312 sleeved on the drive shaft 311, a limiting block 313 disposed at the inner end of the drive shaft 311, and the limiting block 313 having a rectangular structure, two sets of spiral grooves 314 spirally wound on the drive shaft 311, and two sets of balls 315 symmetrically disposed inside the gear 312, with the inner sides of both sets of balls 315 extending into the spiral grooves 314. The pile body 1 has a limiting groove 341 inside that matches the balls 315, and the balls 315 extend into the limiting groove 341. The limiting groove 341 is also provided with... With a support spring 34, the drive component 31 is inserted into the limiting groove 341 through the limiting block 313 and is limited by the limiting groove 341, so it can only perform horizontal extension and retraction on the pile body 1. The support spring 34 pushes the drive component 31 outward through its own elasticity. The gear 312 is located inside the pile body 1 and cannot move inside the pile body 1. When the drive shaft 311 performs extension and retraction, the drive shaft 311 will drive the gear 312 to rotate in the pile body 1 with the cooperation of the spiral groove 314 and the ball 315.

[0040] Furthermore, refer to Figure 9 and Figure 11 The meshing component 32 includes a rack 321 horizontally disposed within the pile body 1, which meshes with a gear 312; an extension shaft 322 vertically disposed at one end of the rack 321; and a socket 323 disposed at the top of the extension shaft 322. A cleaning component 33 is horizontally inserted into the socket 323. The cleaning component 33 includes a connecting rod 331 horizontally inserted into the socket 323, extending outward to the outside of the pile body 1; and a cleaning brush 332 vertically disposed at the outer end of the connecting rod 331. A rectangular groove 333 corresponding to the connecting rod 331 is horizontally disposed on the outer wall of the pile body 1. The two sets of meshing components 32 each have corresponding teeth... The racks 321 are respectively engaged at the upper and lower ends of the gear 312, that is, the two sets of racks 321 are symmetrically positioned. Therefore, when the racks 321 rotate, the two sets of racks 321 will move in opposite directions. The two moving in opposite directions will correspondingly drive the two sets of cleaning components 33 installed on them to move closer or further away from each other. The connecting rod 331 can move along with the movement of the engaging component 32 through the connection with the socket 323. However, the connecting rod 331 can also slide horizontally on the socket 323. Therefore, the cleaning component 33 can move and extend simultaneously under the drive of the engaging component 32.

[0041] Furthermore, refer to Figure 10The pile body 1 has two sets of triangular grooves 35 inside, and the connecting rod 331 is inserted into the triangular groove 35. The triangular groove 35 is triangular in shape, and the hypotenuse of the triangular structure is connected to the end of the connecting rod 331. One end of the triangular groove 35 has a guide groove 351, and the rack 321 is located in the guide groove 351. The guide groove 351 can limit the movement direction of the rack 321, so that the rack 321 can slide and translate within the guide groove 351. One end of the connecting rod 331 abuts against the hypotenuse of the triangular groove 35. Therefore, when the connecting rod 331 moves within the triangular groove 35, it will extend and retract along the hypotenuse of the triangular groove 35.

[0042] During the docking process between the AGV and the charging component 25, combined with Figure 10 and Figure 11 The AGV (Automated Guided Vehicle) will first contact the drive component 31 and cleaning component 33 outside the charging pile 1, and the cleaning brush 332 will adhere to the charging base plate 4. As the AGV continues to approach the charging pile, the drive component 31 will be squeezed by the AGV and retract into the pile 1. The retracted drive component 31 will drive the gear 312 to rotate through the engagement of the spiral groove 314 and the ball 315. The rotating gear 312 will then mesh with the rack 321, driving the two sets of meshing components 32 to move their respective cleaning components 33 in opposite directions. During the movement of the cleaning components 33, the cleaning brush 332 will move horizontally along the outer wall of the charging base plate 4, and during the movement, the cleaning brush 332 will clean the charging base plate. 4. Wiping away dust adhering to the outer wall: The two sets of cleaning components 33 move synchronously, starting from the middle of the charging substrate 4, wiping away the dust adhering to the outer wall of the charging substrate 4 to both sides, so that the charging substrate 4 is in a clean state for subsequent charging docking operations. At the same time, when the connecting rod 331 moves with the cleaning component 33, it will be subjected to pressure transmitted from the charging substrate 4 and the cleaning brush 332, so that the connecting rod 331 will move along the inclined side of the triangular groove 35 during the translation process. As the cleaning brush 332 is translated, the connecting rod 331 will be driven to retract. The retraction method allows the cleaning component 33 to fit against the outer wall of the pile body 1 after cleaning the outer wall, without obstructing the docking between the charging substrate 4 and the charging component 25, facilitating subsequent charging operations.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
