[0040] The embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and should not be understood as a limitation to the present application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] like Figure 1 As shown, a Cartesian coordinate system is established. The length direction of the plug docking mechanism 1000 is defined to be parallel to the x-axis, the width direction to be parallel to the y-axis, and the height direction to be parallel to the z-axis. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the structures in the plug docking mechanism 1000 and should not be construed as limitations on this application.

[0046] A plug docking mechanism 1000 is provided in the embodiments, which can be used in a charging pile. The charging pile can be used to charge an AGV.

[0047] As shown in Figure 1 and Figure 2 , the plug docking mechanism 1000 can include a base 100, a guide unit 200, an elastic member 300, and a plug 400. The base 100 can be used as a mounting carrier in the plug docking mechanism 1000, and other structures in the plug docking mechanism 1000 can be mounted on the base 100. The base 100 can include a first end 101 and a second end 102 along the length direction of the plug docking mechanism 1000.

[0048] The guide unit 200 can include a guide seat 210 and a guide rod set 220. The guide seat 210 can be fixedly installed on the base 100 by screw connection, adhesion, clamping, or welding, and is arranged close to the first end 101 of the base 100. In addition, the guide seat 210 is also provided with a guide hole set 2105 extending in the first direction. The guide hole set 2105 can include an unlocking section and a guide section in communication, wherein the unlocking section is arranged close to the second end 102 relative to the guide section.

[0049] The guide rod set 220 can be movably inserted into the guide hole set 2105 and can slide in the guide hole set 2105 in the first direction to reciprocate between the unlocking section and the guide section. When the guide rod set 220 is located in the unlocking section, the guide rod set 220 can move in the second direction and the third direction in the guide hole set 2105. When the guide rod set 220 is located in the guide section, the guide section can provide a guide function for the guide rod set 220 in the second direction and the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. In some embodiments, the first direction can be parallel to the length direction of the plug docking mechanism 1000, the second direction can be parallel to the width direction of the plug docking mechanism 1000, and the third direction can be parallel to the height direction of the plug docking mechanism 1000.

[0050] The elastic member 300 can extend in the first direction. One end of the elastic member 300 can abut against the second end 102 of the base 100, and the other end of the elastic member 300 can abut against the guide rod set 220. When the guide rod set 220 is not subjected to external force, the elastic member 300 can be in a compressed or naturally elongated state. The plug 400 can be fixedly connected to the side of the guide rod set 220 away from the elastic member 300. The insertion direction of the plug 400 can be parallel to the first direction.

[0051] When the plug 400 of the plug docking mechanism 1000 is docked with the AGV, the plug 400 will be subjected to a pressure applied by the AGV in parallel with the first direction. During this process, the pressure applied to the plug 400 can be transmitted to the elastic member 300 through the guide rod set 220 in sequence, and the elastic member 300 is compressed and deformed. At the same time, the guide rod set 220 can be moved from the guide section to the unlocking section of the guide hole set 2105. When the guide rod set 220 is in the unlocking section, the guide rod set 220 can move in the second direction and the third direction, so that the position of the plug 400 in the second direction and the third direction can be adjusted to accurately dock the plug 400 with the AGV. When the pressure applied to the plug 400 is removed, the elastic member 300 can drive the guide rod set 220 to move from the unlocking section to the guide section of the guide hole set 2105 and reset. When the guide rod set 220 moves to the guide section, the guide section can guide the guide rod set 220 in the second direction and the third direction to ensure that the guide rod set 220 is accurately reset, thereby also ensuring that the plug 400 is accurately reset and centered in the second direction and the third direction, which can reduce the possibility of deviation of the plug 400 and ensure that the plug docking mechanism can be successfully connected with the AGV next time.

[0052] As shown in Figure 1 and Figure 2 , the base 100 can include a base body 110 and an abutting plate 120. The base body 110 can have a generally inverted U-shaped structure. The abutting plate 120 can be fixedly installed on one end of the base body 110 close to the second end 102 by welding, screw connection or clamping, etc. The guide seat 210 can be fixedly installed on one end of the base body 110 close to the first end 101. The abutting plate 120 can be spaced from the guide seat 210.

[0053] In some embodiments, the elastic member 300 can be a spring. The side of the abutting plate 120 close to the guide seat 210 can be provided with a second guide column 130. The second guide column 130 can be fixed to the abutting plate 120 by clamping, screw connection or welding, etc. The end of the elastic member 300 away from the guide rod set 220 can be sleeved on the second guide column 130 and abut against the side of the abutting plate 120 close to the guide seat 210, which can reduce the probability of the elastic member 300 being separated from the abutting plate 120. Of course, in some embodiments, the end of the elastic member 300 close to the abutting plate 120 can also be fixedly connected with the abutting plate 120 by bonding or welding, etc.

[0054] In other embodiments, the elastic member 300 can also be a flexible column or the like, and the end of the elastic member 300 close to the abutting plate 120 can be bonded to the side of the abutting plate 120 close to the guide seat 210.

[0055] As shown in Figure 1 and Figure 2As shown, the guide rod assembly 220 may include two sets of first guide rods 221 and second guide rods 222. Additionally, the guide rod assembly 220 includes a mounting block 223, which is generally cuboid in shape. The two first guide rods 221 and the two second guide rods 222 can be alternately and sequentially fixedly installed around the perimeter of the mounting block 223. Furthermore, the first guide rods 221 may be parallel to the height direction of the plug docking mechanism 1000, and the two first guide rods 221 are coaxial. The second guide rods 222 may be parallel to the width direction of the plug docking mechanism 1000, and the two second guide rods 222 are coaxial. Accordingly, the guide rod assembly 220 may be cross-shaped. In the embodiment, both the first guide rods 221 and the second guide rods 222 can be fixedly connected to the mounting block 223 by means of screw connection, bonding, snap-fit, or welding.

[0056] In this embodiment, the mounting block 223 may be opposite to the abutment plate 120. A first guide post 224 may protrude from the side of the mounting block 223 near the abutment plate 120. One end of the elastic member 300 near the guide rod assembly 220 may be sleeved on the first guide post 224 and abut against the side of the mounting block 223 near the abutment plate 120. This prevents misalignment between the elastic member 300 and the guide rod assembly 220, ensuring stable contact between the elastic member 300 and the guide rod assembly 220 and reducing the probability of the elastic member 300 detaching from the guide rod assembly 220. Of course, in some embodiments, the end of the elastic member 300 near the mounting block 223 may also be fixedly connected to the mounting block 223 by bonding or welding.

[0057] like Figure 2 and Figure 3 As shown, the guide seat 210 may include a first side plate 2101, a second side plate 2102, a third side plate 2103, and a fourth side plate 2104 connected in sequence. The first side plate 2101, the second side plate 2102, the third side plate 2103, and the fourth side plate 2104 can cooperate to form a closed frame. The cross-section of the guide seat 210 perpendicular to the first direction can be rectangular. Specifically, the first side plate 2101 and the third side plate 2103 can be perpendicular to the third direction, and the second side plate 2102 and the fourth side plate 2104 can be perpendicular to the second direction. The third side plate 2103 can be fixedly installed on the base body 110.

[0058] The guide seat 210 has two sets of first guide holes 211 and second guide holes 212. Both the first guide holes 211 and the second guide holes 212 extend along a first direction. One first guide hole 211 is formed on the first side plate 2101, and the other first guide hole 211 is formed on the third side plate 2103. The projection of the first guide hole 211 on the first side plate 2101 onto the third side plate 2103 can coincide with the first guide hole 211 on the third side plate 2103.

[0059] In addition, a second guide hole 212 can be formed on the second side plate 2102, and another second guide hole 212 can be formed on the fourth side plate 2104. The projection of the second guide hole 212 on the second side plate 2102 on the fourth side plate 2104 can coincide with the second guide hole 212 on the fourth side plate 2104.

[0060] Two first guide rods 221 can be correspondingly and movably inserted into the two first guide holes 211, and two second guide rods 222 can be correspondingly and movably inserted into the two second guide holes 212. In the embodiment, the base body 110 can be provided with an avoiding hole 111 opposite to and in communication with the first guide hole 211 on the third side plate 2103, so that the corresponding first guide rod 221 can be smoothly inserted into the first guide hole 211 on the third side plate 2103.

[0061] Further combined Figure 4 The first guide hole 211 can include a first unlocking section 2111, a first guide section 2112 and a first positioning section 2113 in sequence. The first unlocking section 2111 can be located at one end of the first guide section 2112 close to the second end 102. The first guide rod 221 is movably inserted into the first guide hole 211 and can move back and forth between the first unlocking section 2111, the first guide section 2112 and the first positioning section 2113.

[0062] In the embodiment, the size of the first unlocking section 2111 in the second direction can be greater than the diameter of the first guide rod 221. When the cross section of the first guide rod 221 is non-circular, the diameter of the first guide rod 221 can refer to the diameter of the largest circumscribed circle of the cross section of the first guide rod 221. Thus, when the first guide rod 221 is in the first unlocking section 2111, the first guide rod 221 can move in the first unlocking section 2111 along the second direction.

[0063] The size of the first positioning section 2113 in the second direction can be equal to or less than the diameter of the first guide rod 221. In some embodiments, the first positioning section 2113 can be substantially arc-shaped groove structure and face the first guide section 2112. When the first guide rod 221 moves to the first positioning section 2113, part of the first guide rod 221 can be accommodated in the first positioning section 2113, and the first positioning section 2113 can provide positioning for the first guide rod 221 in the second direction, preventing the first guide rod 221 from moving in the second direction.

[0064] The first guide segment 2112 extends from one end near the first unlocking segment 2111 to one end near the first positioning segment 2113, and its size can gradually decrease in the second direction. That is, the first guide segment 2112 can be approximately V-shaped and can connect the first unlocking segment 2111 and the first positioning segment 2113. Accordingly, when the first guide rod 221 is located in the first guide segment 2112 and gradually moves closer to the first positioning segment 2113, the first guide segment 2112 can provide a guiding function for the first guide rod 221 in the second direction, allowing the first guide rod 221 to gradually reset and center in the second direction.

[0065] like Figure 2 and Figure 3 As shown, the second guide hole 212 may include a second unlocking section 2121, a second guide section 2122, and a second positioning section 2123 connected in sequence. The second unlocking section 2121 may be located at the end of the second guide section 2122 near the second end 102. The second guide rod 222 is movably inserted into the second guide hole 212 and can move back and forth between the second unlocking section 2121, the second guide section 2122, and the second positioning section 2123.

[0066] In this embodiment, the dimension of the second unlocking segment 2121 in the third direction can be larger than the diameter of the second guide rod 222. When the cross-section of the second guide rod 222 is non-circular, the diameter of the second guide rod 222 can refer to the diameter of the maximum circumscribed circle of the cross-section of the second guide rod 222. Therefore, when the second guide rod 222 is in the second unlocking segment 2121, the second guide rod 222 can move in the first unlocking segment 2111 in the third direction.

[0067] The dimension of the second positioning segment 2123 in the third direction may be equal to or smaller than the diameter of the second guide rod 222. In some embodiments, the second positioning segment 2123 may be generally an arcuate groove structure and face the second guide segment 2122. When the second guide rod 222 moves to the second positioning segment 2123, a portion of the second guide rod 222 may be accommodated in the second positioning segment 2123, and the second positioning segment 2123 may provide positioning for the second guide rod 222 in the third direction, preventing the second guide rod 222 from moving in the third direction.

[0068] The second guiding section 2122 can gradually decrease in size in the third direction from the end close to the second unlocking section 2121 to the end close to the second positioning section 2123. That is, the second guiding section 2122 can be substantially V-shaped and connected between the second unlocking section 2121 and the second positioning section 2123. Accordingly, when the second guiding rod 222 is located in the second guiding section 2122 and gradually approaches the second positioning section 2123, the second guiding section 2122 can provide a guiding function in the third direction for the second guiding rod 222, so as to gradually reset the second guiding rod 222 in the second direction.

[0069] In the embodiment, when the guiding rod set 220 is not subjected to external force, the guiding rod set 220 can abut against the end of the guiding hole set 2105 away from the abutting plate 120 under the action of the elastic member 300. Specifically, the first guiding rod 221 can be positioned in the first positioning section 2113 and abut against the inner wall of the first positioning section 2113. The second guiding rod 222 can be positioned in the second positioning section 2123 and abut against the inner wall of the second positioning section 2123.

[0070] In other embodiments, the guiding rod set 220 can also include a set of first guiding rods 221 and second guiding rods 222. The guiding hole set 2105 can also include a set of first guiding holes 211 and second guiding holes 212.

[0071] As shown in FIGS. 1, 2 and 3, the plug connecting mechanism 1000 can further include a connecting rod 500. One end of the connecting rod 500 can be fixedly connected to the mounting block 223 by means of clamping, interference fit, bonding, welding or screw connection, etc. The connecting rod 500 protrudes from the side of the mounting block 223 away from the elastic member 300. In addition, the connecting rod 500 can be coaxial with the elastic member 300. In the embodiment, the plug 400 can be fixedly connected to the end of the connecting rod 500 away from the mounting block 223. Figure 1 Figure 2 As shown in FIGS. 1, 2 and 3, the plug connecting mechanism 1000 can further include a connecting rod 500. One end of the connecting rod 500 can be fixedly connected to the mounting block 223 by means of clamping, interference fit, bonding, welding or screw connection, etc. The connecting rod 500 protrudes from the side of the mounting block 223 away from the elastic member 300. In addition, the connecting rod 500 can be coaxial with the elastic member 300. In the embodiment, the plug 400 can be fixedly connected to the end of the connecting rod 500 away from the mounting block 223.

[0072] In the embodiment, the plug 400 can be fixedly installed on the end of the connecting rod 500 away from the mounting block 223 by means of the mounting seat 600. Specifically, the mounting seat 600 can be fixedly connected to the end of the connecting rod 500 away from the mounting block 223 by means of screw connection, bonding or clamping, etc., and the mounting seat 600 can be symmetrical about the connecting rod 500. The plug 400 can be fixedly installed on the end of the mounting seat 600 away from the connecting rod 500 by means of screw connection or clamping, etc., which can facilitate the relative plug-in connection between the plug 400 and the AGV vehicle.

[0073] ​In some embodiments, the plug docking mechanism 1000 further comprises four guide wheels 700, each of which is rotatably mounted to the mounting base 600 away from the side of the base 100. The rotation axis of the guide wheel 700 can be parallel to the height direction of the plug docking mechanism 1000. And the four guide wheels 700 can be symmetrically arranged on both sides of the mounting base 600, specifically, the four guide wheels 700 can be symmetrically arranged about the connecting rod 500. In addition, the guide wheel 700 can protrude relative to the side edge of the mounting base 600.

[0074] When the plug docking mechanism 1000 is plugged with the AGV trolley, the mounting base 600 can be inserted into the corresponding structure of the AGV trolley, and the guide wheel 700 can act on the corresponding structure in the AGV trolley to provide a guiding function, facilitating the accurate alignment of the plug 400 and the AGV trolley.

[0075] In other embodiments, the guide wheel 700 can also be arranged in one, two, or six, etc.

[0076] In other embodiments, the rotation axis of the guide wheel 700 can also be parallel to the width direction of the plug docking mechanism 1000.

[0077] When the plug docking mechanism 1000 is plugged with the AGV trolley, the AGV trolley will exert a pressure on the plug 400 and the mounting base 600 parallel to the first direction. The plug 400 and the mounting base 600 can transmit the pressure to the guide rod group 220 through the connecting rod 500, and the guide rod group 220 can move towards the abutting plate 120 and press the elastic member 300, which can store elastic potential energy under the action of extrusion. In this process, the first guide rod 221 can gradually move to the first unlocking section 2111, and the second guide rod 222 can move to the second unlocking section 2121, and the guide rod group 220 can move in the second direction and the third direction. Accordingly, the plug 400 can also adjust its position in the second direction and the third direction to adapt to the position of the AGV trolley, so that the plug 400 and the AGV trolley are accurately aligned and plugged.

[0078] When the plug 400 and the mounting base 600 are not subjected to external force, i.e. the AGV trolley is separated from the plug docking mechanism 1000, the guide rod group 220 can gradually move away from the abutting plate 120 under the action of the elastic member 300. When the guide rod group 220 moves to the guide section, i.e. the first guide rod 221 moves to the first guide section 2112, and the second guide rod 222 moves to the second guide section 2122, the guide section can provide the guide rod group 220 with a guide in the second direction and the third direction, so that the guide rod group 220 gradually resets and centers in the second direction, and the guide rod group 220 gradually resets and centers in the third direction. Thus, the plug 400 can also gradually reset and center in the second direction and the third direction for the next alignment and plugging with the AGV trolley.

[0079] Therefore, the plug docking mechanism 1000 provided by the application has simple structure and low cost. Meanwhile, the plug can be reset accurately after use, which can improve the safety and reliability of use.

[0080] In addition, the embodiment also provides a charging pile, which can include the plug docking mechanism 1000 provided by the embodiment.
