Description

Technical Field

[0001] The present invention relates to the field of automatic charging, and particularly to a charging pile. Background Art

[0002] At present, when an automatic guided vehicle (AGV) charges automatically, it will automatically move to the position of the charging pile to dock the charging port with the charging pile to supplement electric energy. Due to factors such as the running error of the AGV itself and the uneven ground, there will be a position deviation between the charging port of the AGV and the charging pile. The deviations include: left - right (X) deviation, front - back (Y) deviation, up - down (Z) deviation, as well as the torsional deviation with the X - direction as the rotation axis, the torsional deviation with the Y - direction as the rotation axis, and the torsional deviation with the Z - direction as the rotation axis.

[0020] The following will describe the embodiments of the present invention in detail with reference to the drawings.

[0021] It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a charging pile, including: a base 1, on which a first upright post 5 and a second upright post 6 are provided. The first upright post 5 and the second upright post 6 are arranged oppositely, and a cross bar 9 is connected between the first upright post 5 and the second upright post 6; an arm body 2 is provided between the first upright post 5 and the second upright post 6. A charging end 4 is connected to the first end of the arm body 2. A sliding hole 21 is formed in the arm body 2, and the arm body 2 is sleeved on the cross bar 9 through the sliding hole 21; a first elongated hole 51 is formed in the first upright post 5 along the height direction of the first upright post 5, and a second elongated hole is formed in the second upright post 6 along the height direction of the second upright post 6; the first end of the cross bar 9 is inserted into the first elongated hole 51, and the second end is inserted into the second elongated hole; a first elastic adjusting component for adjusting the height of the cross bar 9 is connected to the first end of the cross bar 9, and a second elastic adjusting component for adjusting the height of the cross bar is connected to the second end.

[0023] In this embodiment, the arm body 2 can slide along the cross bar 9 between the first upright post 5 and the second upright post 6, so that when the charging end 4 connected to the arm body 2 is docked with the charging port of the automatic guided vehicle, it can adapt to the deviation along the length direction of the cross bar 9; the cross bar 9 can slide along the height directions of the first upright post 5 and the second upright post 6. Therefore, the arm body 2 connected to the cross bar 9 can also move along the height directions of the first upright post 5 and the second upright post 6 with the cross bar 9, so that when the charging end 4 connected to the arm body 2 is docked, it can adapt to the deviation along the height directions of the first upright post 5 and the second upright post 6, improving the anti-deviation ability during charging docking of the existing charging pile. The first elastic adjusting component and the second elastic adjusting component can make the cross bar 9 return to the original position when the charging port is separated from the charging end 4, so that the arm body 2 connected to the cross bar 9 and the charging end 4 connected to the arm body 2 return to the original position.

[0024] Optionally, the first elastic adjusting component and the second elastic adjusting component can be any component with a reset function.

[0025] As Figure 2As shown, in an alternative embodiment of Embodiment 1 of the present invention, the first elastic adjustment component includes a first rod member 93 provided at the first end of the cross bar 9; a first support plate 12 is provided at the top of the first upright column 5, a first through hole is formed in the first support plate 12, the first end of the first rod member 93 is connected to the cross bar 9, and the second end passes through the first through hole and is connected to a first pressing plate 13. A first return spring 14 is sleeved on the first rod member 93 between the first pressing plate 13 and the first support plate 12; the second elastic adjustment component includes a second rod member provided at the second end of the cross bar; a second support plate is provided at the top of the second upright column, a second through hole is formed in the second support plate, the first end of the second rod member is connected to the cross bar, and the second end passes through the second through hole and is connected to a second pressing plate. A second return spring is sleeved on the second rod member between the second pressing plate and the second support plate.

[0026] In this embodiment, the first rod member 93 and the second rod member symmetrically arranged with respect to the cross bar 9 cooperate with the first through hole and the second through hole respectively, and can guide the cross bar 9 to slide along the height directions of the first upright column 5 and the second upright column 6, so that the arm body 2 connected to the cross bar 9 and the charging end 4 connected to the arm body 2 can adapt to the position deviation along the height directions of the first upright column 5 and the second upright column 6. When the charging port is separated from the charging end 4, under the action of the elastic forces of the first return spring 14 and the second return spring, the first rod member 93 and the second rod member can return to their original positions, so that the charging end 4 returns to its original position and waits for the next docking with the charging port.

[0027] As Figure 2 shown, in an alternative embodiment of Embodiment 1 of the present invention, a first nut 91 is connected to the first end of the cross bar 9, the first rod member 93 is a first screw rod 93, and the first end of the first screw rod 93 is threadedly connected to the first nut 91; a second nut is connected to the second end of the cross bar, the second rod member is a second screw rod, and the first end of the second screw rod is threadedly connected to the second nut.

[0028] In this embodiment, through the cooperation between the first screw rod 93 and the first nut 91, the second screw rod and the second nut provided at both ends of the cross bar 9, the cross bar 9 can be leveled, and when the charging end 4 cannot return to its original position due to the long-term use of the charging pile, an error compensation effect can be achieved.

[0029] As Figure 2 shown, in an alternative embodiment of Embodiment 1 of the present invention, a third return spring 7 is provided between the arm body 2 and the first upright column 5, and / or a fourth return spring 8 is provided between the arm body 2 and the second upright column 6.

[0030] In this embodiment, when there is a docking deviation between the charging end 4 and the charging port in the length direction of the cross bar 9, the arm body 2 can slide along the cross bar 9 after being stressed. After the charging port leaves the charging end 4, the third return spring 7 and / or the fourth return spring 8 can drive the arm body 2 to return to its original position and wait for the next docking with the charging port.

[0031] As Figure 2 shown, optionally, the third return spring 7 and / or the fourth return spring 8 is sleeved on the cross bar 9.

[0032] In this embodiment, the cross bar 9 has a guiding effect on the movement of the third return spring 7 and / or the fourth return spring 8.

[0033] As Figure 1 shown, in an alternative embodiment of the first embodiment of the present invention, the first end of the arm body 2 is connected to the charging end 4 through a flexible connector 3.

[0034] In this embodiment, the charging end 4 is connected to the arm body 2 through the flexible connector 3. When the charging end 4 is docked with the charging port of the automated guided vehicle, the flexible connector 3 with flexibility can adapt to the torsional deviation of the charging end 4 in the three coordinate axes directions of the space rectangular coordinate system, improving the anti-deviation ability during the charging docking of the existing charging piles.

[0035] As Figure 3 shown, in an alternative embodiment of the first embodiment of the present invention, the flexible connector 3 includes a first connecting plate 32 and a second connecting plate 31, which are arranged opposite to each other; the first connecting plate 32 is connected to the first end of the arm body 2, the second connecting plate 31 is connected to the charging end 4, and a flexible connecting member 33 is connected between the first connecting plate 32 and the second connecting plate 31.

[0036] In this embodiment, the arm body 2 and the charging end 4 are respectively connected to the flexible connecting member 33 through the first connecting plate 32 and the second connecting plate 31. The arrangement of the first connecting plate 32 and the second connecting plate 31 facilitates the connection between the arm body 2 and the charging end 4 and the flexible connecting member 33.

[0037] Optionally, the flexible connecting member 33 can be one or multiple.

[0038] As Figure 3 shown, in an alternative embodiment of the present invention, the flexible connecting member 33 includes a first flexible connecting member, a second flexible connecting member, and a third flexible connecting member; the first flexible connecting member, the second flexible connecting member, and the third flexible connecting member are arranged in a triangle between the first connecting plate 32 and the second connecting plate 31.

[0039] In this embodiment, since the flexible connecting member 33 is flexible, the first connecting member, the second connecting member, and the third connecting member are distributed in a triangle, which is beneficial to improving the stability of the flexible connector 3 itself.

[0040] Optionally, the flexible connecting member 33 can be made of a flexible material such as a spring or rubber.

[0041] As Figure 3 shown, in an alternative embodiment of the embodiment of the present invention, the flexible connecting member 33 is a spring.

[0042] In this embodiment, a spring is used as the flexible connecting member 33. A spring is a part made of an elastic material that deforms under an external force and returns to its original state after the external force is removed. When there is a deviation in the docking between the charging port and the charging end 4, the charging end 4 connected to the spring can undergo relative displacement under the action of an external force, thereby realizing the docking between the charging end 4 and the charging port. After charging is completed and the charging port leaves the charging end 4, the charging end 4 connected to the spring returns to its original state and waits for the next docking with the charging port.

[0043] As Figure 2 and Figure 4 shown, in an alternative embodiment of the embodiment of the present invention, a positioning post 11 is provided on the base 1; a third elongated hole 23 is formed at the second end of the arm body 2, and the positioning post 11 is located in the third elongated hole 23; the sliding hole 21 is an elongated hole, and the length direction of the sliding hole 21 is parallel to the length direction of the third elongated hole 23; a fifth return spring 10 is connected between the second end of the arm body 2 and the base 11.

[0044] In this embodiment, the positioning post 11 can limit the arm body 2 and prevent the arm body 2 from swinging freely. When there is a docking deviation between the charging port and the charging end 4 in the length direction of the third elongated hole 23, the arm body 2 can slide along the positioning post 11 through the third elongated hole 23, so as to adapt to the docking deviation in the length direction of the third elongated hole 23. After charging is completed and the charging port leaves the charging end 4, the fifth return spring 10 drives the arm body 2 to reset, so that the charging end 4 connected to the arm body 2 returns to its original state and waits for the next docking with the charging port.

[0045] As Figure 2 shown, optionally, the part of the positioning post 11 connected to the arm body 2 is cylindrical.

[0046] In this embodiment, when the part of the positioning post 11 connected to the arm body 2 is cylindrical, the arm body 2 can rotate around the positioning post 11, so as to adapt to the torsional deviation between the charging port and the charging end 4 along the height direction of the positioning post 11.

[0047] As Figure 2 shown, optionally, an anti - detachment gasket 111 is provided at one end of the positioning post 11 away from the base 1.

[0048] In this embodiment, the anti - detachment gasket 111 can prevent the arm body 2 from detaching from the positioning post 1 when moving, improving the reliability of the charging pile.

[0049] As Figure 2 shown, optionally, the positioning post 11 can be fixed to the base 1 through a fixed support shaft 112, and the positioning post 11 is detachably connected to the fixed support shaft 112.

[0050] In this embodiment, when the positioning post 11 is worn due to long - term use of the charging pile, the positioning post 11 can be removed and replaced with a new one, improving the service life of the charging pile.

[0051] As Figure 2 shown, optionally, a first wear - resistant pad is provided on the circumference of the positioning post 11.

[0052] In this embodiment, the positioning post 11 and the arm body 2 can slide relative to each other, and the first wear - resistant pad can reduce the wear of the positioning post 11, thereby improving the service life of the charging pile.

[0053] As Figure 4 shown, optionally, second wear - resistant pads 22 are provided on both sides of the sliding hole 21 or inside the sliding hole 21.

[0054] In this embodiment, as can be seen from the above - mentioned embodiment, since the cooperation between the sliding hole 21 and the cross bar 9 can adapt to deviations in multiple directions, the second wear - resistant pads 22 can reduce or delay the wear of the sliding hole 21, improving the service life of the charging pile.

[0055] The above - mentioned is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
