Description

Technical Field

[0001] The utility model relates to a control mechanism, in particular to a charging control mechanism for an AGV vehicle, belonging to the technical field of AGV vehicle warehousing logistics. Background Art

[0002] As the core equipment of automated logistics, AGV storage trolleys play a crucial role in multiple industries such as automobiles, electronics, and food processing with their efficient, flexible, and intelligent characteristics. Through advanced navigation technologies such as magnetic navigation and visual navigation, they achieve precise positioning and autonomous navigation in complex warehouse environments. Promoting the standardized development of AGV storage trolleys and their charging equipment and improving the compatibility and interchangeability of equipment are important directions for the future development of AGV vehicle warehousing logistics technology.

[0003] Currently, the charging method of AGV storage trolleys generally adopts manual operation, and the charging port is docked by collision. This approach has two major problems: one is that the charging process is not intelligent enough and the efficiency is low, which does not conform to the development trend of AGV technology; the other is that the collision-based docking operation lacks flexibility. In addition, most telescopic mechanism type charging piles are not fully designed considering safety, resulting in waste of resources during the charging process and reducing the overall safety factor. Therefore, a charging control mechanism for an AGV vehicle is proposed. Summary of the Utility Model

[0004] In view of this, the utility model provides a charging control mechanism for an AGV vehicle to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

[0005] The technical solution of the embodiment of the utility model is realized as follows: A charging control mechanism for an AGV vehicle includes a first control component, and a second control component is arranged above the first control component. The first control component includes a control motor, a support seat, a first in-place sensor, a charging pile electrode, a charging pile electrode mounting seat, and a charging pile bellows cover. A control motor is arranged on one side of the support seat, the signal input end of the control motor is in signal connection with the signal output end of the first in-place sensor, a charging pile electrode is installed on the top of the charging pile electrode mounting seat, and a charging pile bellows cover is fixedly connected to the top of the charging pile electrode mounting seat.

[0006] The second control component includes a second in-place sensor, a sliding block gland, and a sliding block. The first in-place sensor and the second in-place sensor are installed on one side of the sliding block gland, and a sliding block is slidably connected to the inner side wall of the sliding block gland.

[0007] Further preferably: An oil-free bushing is slidably connected to the inner side wall of the sliding block.

[0008] Further preferably, two charging electrode springs are symmetrically and fixedly connected to the bottom of the sliding block.

[0009] Further preferably, an AGV vehicle-mounted charging electrode is installed at the bottom end of the charging electrode spring.

[0010] Further preferably, a motor bracket is fixedly connected to one side of the control motor, and the motor bracket is fixedly connected to one side of the support seat.

[0011] Further preferably, an eccentric shaft bearing is provided on the inner side wall of the support seat.

[0012] Further preferably, a bearing cover is fixedly connected to one side of the support seat.

[0013] Further preferably, an eccentric shaft is rotatably connected inside the eccentric shaft bearing, one end of the eccentric shaft is fixedly connected to the output shaft of the control motor, and the oil-free bushing is sleeved on the outer side wall of the eccentric shaft.

[0014] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0015] First, the present invention drives the slider to move by the operation of the control motor, so that the AGV vehicle-mounted charging electrode contacts the charging pile electrode to complete automatic charging. The control method of using an eccentric shaft plus a motor enables the motor to only run one circle within a controllable range, thereby ensuring the safety of the motor. The travel of the AGV vehicle charging electrode can not only ensure reliable contact with the charging pile electrode, but also enable the charging pile electrode to be reliably disconnected after charging is completed.

[0016] Second, the present invention can protect the charging electrode. The AGV vehicle-mounted charging electrode is in an uncharged state before contacting the charging pile electrode, preventing the generation of electric arcs and reducing the wear of the electrode.

[0017] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the above-described illustrative aspects, embodiments, and features, other aspects, embodiments, and features of the present invention will be readily apparent by reference to the drawings and the following detailed description.

Detailed implementation manners

[0023] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0024] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0025] As Figures 1 - 3 shown, an AGV vehicle charging control mechanism provided by an embodiment of the present utility model includes a first control component 10, and a second control component 20 is disposed above the first control component 10. The first control component 10 includes a control motor 11, a support seat 12, a first in-place sensor 13, a charging pile electrode 14, a charging pile electrode mounting seat 15, and a charging pile bellows cover 16; a control motor 11 is disposed on one side of the support seat 12, a signal input end of the control motor 11 is in signal connection with a signal output end of the first in-place sensor 13, a charging pile electrode 14 is mounted on the top of the charging pile electrode mounting seat 15, and the charging pile electrode mounting seat 15 is fixedly connected to the charging pile bellows cover 16 at the top;

[0026] The second control component 20 includes a second in-place sensor 21, a slider gland 22, and a slider 23; the first in-place sensor 13 and the second in-place sensor 21 are mounted on one side of the slider gland 22, the inner side wall of the slider gland 22 is slidably connected to the slider 23, and the first in-place sensor 13 and the second in-place sensor 21 are used to detect the position of the slider 23 and send signals to the control motor 11.

[0027] In this embodiment, specifically: an oil-free bushing 24 is slidably connected to the inner side wall of the slider 23.

[0028] In this embodiment, specifically: Two charging electrode springs 26 are symmetrically and fixedly connected to the bottom of the sliding block 23. The charging electrode springs 26 can enhance the contact stability between the electrodes, thereby enabling more stable charging.

[0029] In this embodiment, specifically: An AGV vehicle-mounted charging electrode 25 is installed at the bottom end of the charging electrode spring 26. The AGV vehicle-mounted charging electrode 25 contacts the charging pile electrode 14 and receives the power from the charging pile, and the AGV cart starts charging.

[0030] In this embodiment, specifically: A motor bracket 210 is fixedly connected to one side of the control motor 11. The motor bracket 210 is fixedly connected to one side of the support seat 12, and the motor bracket 210 is used to install the control motor 11.

[0031] In this embodiment, specifically: An eccentric shaft bearing 28 is provided on the inner side wall of the support seat 12. The eccentric shaft bearing 28 can reduce the wear of the control motor 11.

[0032] In this embodiment, specifically: A bearing cover 29 is fixedly connected to one side of the support seat 12. The bearing cover 29 is used to fix the eccentric shaft bearing 28.

[0033] In this embodiment, specifically: An eccentric shaft 27 is rotatably connected inside the eccentric shaft bearing 28. One end of the eccentric shaft 27 is fixedly connected to the output shaft of the control motor 11. An oil-free bushing 24 is sleeved on the outer side wall of the eccentric shaft 27. The eccentric shaft 27 rotates, causing the oil-free bushing 24 to slide in the groove of the sliding block 23, driving the sliding block 23 to move up and down.

[0034] When the utility model is working: after the AGV vehicle charging control mechanism reaches the charging position, the AGV vehicle controller sends a signal to the control motor 11, and the control motor 11 starts to work, driving the eccentric shaft 27 to rotate, causing the oil-free bushing 24 to slide in the groove of the sliding block 23, driving the sliding block 23 to move downward. When the sliding block 23 reaches the position of the second in-place sensor 21, the control motor 11 stops rotating, so that the charging electrode 25 on the AGV vehicle contacts the charging pile electrode 14, and the AGV vehicle starts to charge. The charging electrode spring 26 can enhance the contact stability between the electrodes, so that the charging is carried out more stably. The eccentric shaft bearing 28 can reduce the wear of the control motor 11. When the AGV vehicle charging control mechanism finishes charging the AGV vehicle, the AGV vehicle controller sends a signal to the control motor 11, and the control motor 11 starts to reverse, driving the eccentric shaft 27 to rotate, causing the oil-free bushing 24 to slide in the groove of the sliding block 23, driving the sliding block 23 to move upward. When it reaches the first in-place sensor 13, the control motor 11 stops rotating, separating the charging electrode 25 on the AGV vehicle from the charging pile electrode 14, and the AGV vehicle is powered off, ensuring that the charging electrode 25 on the AGV vehicle does not contact the charging pile electrode 14 for a long time, avoiding overcharging and overheating problems.

[0035] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
