DETAILED DESCRIPTION

[0048] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0049] See also Figure 1 A floating charging base includes a base 3, a floating component 2 arranged on the base 3, and an electrical connector 1 arranged on the floating component 2.

[0050] The base 3 includes a frame 32 and a protection plate 31. The protection plate 31 and the frame 32 are fixedly connected to enclose a protection cavity 9 for the floating component 2 to move. The floating component 2 moves in the protection cavity 9 to compensate for displacement.

[0051] When the AGV approaches the floating charging seat, the protection plate 31 and the frame 32 can protect the floating component 2 to prevent the floating component 2 from being touched by the AGV or the cargo on the AGV, so that the floating component 2 can be displaced normally, which is beneficial to ensure that the electrical connector 1 on the floating component 2 is reliably electrically connected to the AGV.

[0052] The floating assembly 2 includes a frame 21 and a floating plate 22. The frame 21 is disposed on a frame 32, and the floating plate 22 is movably disposed between the frame 21 and the protection plate 31. The electrical connector 1 is fixed on the floating plate 22 and moves with the floating plate 22.

[0053] The floating plate 22 is located between the charging seat and the electrical connector 1, further enhancing the protection of the floating plate 22. When the AGV is connected to the floating charging seat, even if the goods on the AGV touch the frame 21 or the protection plate 31, the floating plate 22 can still drive the electrical connector 1 to float, thereby ensuring the matching connection between the electrical connector 1 and the AGV.

[0054] Specifically, the floating plate 22 is movably connected to the frame 21 .

[0055] In other embodiments, the floating plate 22 is movably connected to the protection plate 31 .

[0056] See also Figure 1-9 In this embodiment, the length direction of the protection plate 31 is the first direction, and the width direction of the protection plate 31 is the second direction. The floating plate 22 can move in a plane along the first direction and the second direction.

[0057] When the AGV is docked with the charging station, even if the AGV deviates from the plane of the floating plate 22, the floating plate 22 can adjust the plane position of the electrical connector 1 by moving in the first direction and the second direction, so that the electrical connector 1 is aligned with the AGV to ensure electrical connection.

[0058] The frame 21 is provided with a first reset member 4 connected to the floating plate 22. When the charging seat and the AGV are connected, the electric connector 1 is displaced by the force of the AGV, and the floating plate 22 moves accordingly. When the charging seat and the AGV are separated, the first reset member 4 drives the floating plate 22 to move, so that the electric connector 1 returns to the initial position.

[0059] Specifically, the first resetting member 4 is an elastic member. The floating plate 22 is connected to the frame 21 through the first resetting member 4. The first resetting member 4 can not only reset the floating plate 22, but also support the floating plate 22 to move between the frame 21 and the protection plate 31.

[0060] In this embodiment, a mounting portion 222 is provided on the side of the floating plate 22 facing away from the electrical connector 1, and the mounting portion 222 is located at the center of the surface of the floating plate 22. The first reset member 4 is a first reset spring 41. One end of the first reset spring 41 is fixed to the mounting portion 222, and the other end is fixed to the frame 21. When the force on the electrical connector 1 and the floating plate 22 disappears, the first reset spring 41 elastically recovers to drive the floating plate 22 and the electrical connector 1 to reset.

[0061] There are four first return springs 41 connected to four corners of the frame 21 respectively, so that the length directions of all the first return springs 41 are different. When the four first return springs 41 are in a force balance state, the floating plate 22 is located in the middle of the frame 21.

[0062] The frame 21 is provided with five through holes, namely through hole 1a, through hole 1b, through hole, through hole 1d, and through hole 1e. The ends of the four first return springs 41 away from the mounting portion 222 are fixed with hooks, namely hook 2a, hook 2b, hook 2c, and hook 2d. When the floating plate 22 is mounted to the frame 21, the hook 2a, hook 2b, hook 2c, and hook 2d are hooked on the through hole 1a, through hole 1b, through hole 1c, and through hole 1d, respectively, so that the first return springs 41 of the four different schemes are in a stretched state.

[0063] In other embodiments, the floating plate 22 is connected to the frame 21 only through the first return spring 41 , and the first return spring 41 is required to offset the gravity of the floating plate 22 and the electrical connector 1 .

[0064] In this embodiment, the frame 21 is provided with a support member 6 for offsetting the weight of the floating plate 22. The support member 6 offsets the weight of the floating plate 22, reducing the influence of the weight of the floating plate 22 on the floating and resetting of the floating plate 22, which is conducive to ensuring reliable electrical connection.

[0065] The support member 6 is a support spring 61 located directly above the floating plate 22. The upper end of the support spring 61 is fixed to the upper part of the frame 21, and the lower end of the support spring 61 is fixed to the mounting portion 222 of the floating plate 22.

[0066] The upper end of the support spring has a hook 2e, and when the floating plate 22 is installed on the frame 21, the hook 2e is hooked on the through hole 1e. The support spring offsets the gravity of the floating plate 22 and the electrical connector 1 by elastic force.

[0067] A groove 7 for accommodating the floating plate 22 is provided on one side of the frame 21 facing the protective plate 31, and the depth of the groove 7 is greater than the thickness of the floating plate 22. When the moving finger of the frame 21 contacts the protective plate 31, the groove 7 can completely accommodate the floating plate 22. The floating plate 22 can move in the groove 7, and compared with a frame 21 without the groove 7, the floating plate 22 can be prevented from lifting the frame 21, thereby reducing the possibility of erroneous displacement of the frame 21.

[0068] The length direction of the electrical connector 1 is the third direction. The frame 21 can move along the third direction and drive the floating plate 22 to approach or move away from the protection plate 31, thereby driving the electrical connector 1 to perform telescopic movement.

[0069] Specifically, a guide post 8 is disposed in the protection cavity 9 between the frame 32 and the protection plate 31. One end of the guide post 8 is fixed to the frame 32, and the other end is fixed to the protection plate 31. The frame 21 is slidably connected to the guide post 8.

[0070] In this embodiment, the guide column 8 is provided with a second reset member 5. When the external force acting on the floating mechanism disappears, the second reset member 5 pushes the frame 21 to move to the protection plate 31, and the floating plate 22 is clamped between the protection plate 31 and the frame 21.

[0071] In other embodiments, the second resetting member 5 is a cylinder, and the frame 21 is fixed on the cylinder and performs telescopic movement along the third direction with the cylinder.

[0072] In this embodiment, the frame 21 is slidably connected to the guide post 8 and can be tilted relative to the guide post 8. The axis of the guide post 8 is perpendicular to the plane of the protection plate 31. Therefore, the guide post 8 has an active angle relative to the plane of the protection plate 31.

[0073] Specifically, the frame 21 is provided with a sliding hole 211 for the guide column 8 to pass through, and the diameter of the sliding hole 211 is larger than the width of the guide column 8, so that there is a movable gap between the sliding hole 211 and the guide column 8.

[0074] When the deflection angle of the AGV joint relative to the plane of the protection plate 31 is less than 10 degrees, the electrical connector 1 needs to be deflected by a corresponding angle to ensure reliable electrical connection between the electrical connector 1 and the AGV.

[0075] The sliding hole 211 and the guide column 8 have a movable gap, and the frame 21 can be tilted relative to the plane of the protection plate 31. The frame 21 drives the floating plate 22 to tilt, and then drives the electrical connector 1 to deflect a corresponding angle, so that the electrical connector 1 and the AGV can be docked smoothly.

[0076] Specifically, there are two racks 32, which are respectively fixed to the upper part and the lower part of the protection plate 31 and are located on the same surface of the protection plate 31. Two guide posts 8 are fixed between the single frame 21 and the protection plate 31.

[0077] The frame 32 includes a limiting rod 321 , two fixing rods 323 , and two connecting rods 322 .

[0078] The frame 32 is in an “n” shape and is an integrally formed structure. Two connecting rods 322 fix two ends of the limiting rod 321 respectively, and two fixing rods 323 are fixed on the protection plate 31 and connect the two connecting rods 322 respectively.

[0079] The limiting rod 321 is located at a side away from the protection plate 31. The guide column 8 is fixed on the limiting rod 321 to ensure that the guide column 8 has a sufficient length, which is conducive to increasing the movable distance of the frame 21 in the third direction.

[0080] The second return spring 51 is sleeved on the guide post 8 , one end of the second return spring 51 abuts against the frame 21 , and the other end of the second return spring 51 abuts against the limit rod 321 , so as to press the frame 21 onto the protection plate 31 .

[0081] When no external force acts on the electrical connector 1, the frame 21 is acted upon by the second return spring 51 to press against the protective plate 31, and the floating plate 22 is accommodated in the groove 7; the floating plate 22 is acted upon by the first return spring 41 and the supporting spring to overcome the self-gravity of the floating plate 22, so that the electrical connector 1 on the floating plate 22 stops at the center of the protective plate 31.

[0082] A window 311 is formed on the surface of the protection plate 31 . The width of the window 311 is greater than the width of the electrical connector 1 so that the electrical connector 1 on the floating plate 22 can extend out of the window 311 .

[0083] The floating plate 22 has a protruding boss 221 on its surface for fixing the electrical connector 1. The boss 221 extends out of the window 311, and the side wall of the boss 221 is used to abut against the edge of the window 311. The boss 221 abuts against the edge of the window 311 to limit the range of planar movement of the floating plate 22, thereby limiting the range of planar movement of the electrical connector 1, which helps to ensure that the electrical connector 1 floats within a specified range. In addition, compared with the side wall of the electrical connector 1 abutting against the edge of the window 311 for position limiting, the boss 221 can reduce the wear of the side wall of the electrical connector 1, thereby improving the reliability of the electrical connector 1.

[0084] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
