Description

Technical Field

[0001] This utility model relates to the field of intelligent charging technology for AGVs, specifically an adaptive charging floating mechanism. Background Technology

[0002] AGVs (Automated Guided Vehicles) have been widely used and developed in recent years as an advanced logistics and manufacturing automation solution. AGVs have not only improved production efficiency and reduced labor costs, but have also played an important role in hazardous environments.

[0003] Currently, there are roughly two methods for charging AGVs:

[0004] 1. Cable type: The AGV is guided to the charging interface by its automatic guidance function. Then, the plug cable on the AGV is pulled by the user to complete the charging action.

[0005] 2. Adaptive plug-in type, which means that the AGV is guided to the charging pile through its automatic guidance function, and then the charging interface is aligned with the charging connector of the charging pile through its own control, and then the forward movement is performed to complete the charging action.

[0006] However, during the adaptive charging process of AGV, the charging interface of AGV and the charging connector of charging pile are often not completely sealed due to the working environment (mainly the uneven road surface on which AGV travels). If AGV continues to perform forward charging action at this time, it is very easy to damage the plug.

[0007] Therefore, there is an urgent need for an adaptive charging floating mechanism to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide an adaptive charging floating mechanism that improves the ability to correct deviations when the AGV is docking with the charging pile, making the docking of the AGV with the charging pile smoother.

[0009] To achieve the above objectives, this utility model employs the following technical solution:

[0010] The main structure includes left and right floating components, with front and rear floating components on the sides of the left and right floating components, and an adaptive connection component at the end of the front and rear floating components, and a charging pile male connector component at the end of the adaptive connection component.

[0011] Preferably, the left and right floating components include a floating mechanism mounting plate, at least one optical axis is provided between the two side walls of the floating mechanism mounting plate, a floating slider is sleeved on the at least one optical axis, and a first compression spring is sleeved between the floating slider and the two side walls of the floating mechanism mounting plate; a mounting seat is provided on the floating slider, and a front and rear floating component is mounted on the mounting seat.

[0012] Preferably, the mounting base is a U-shaped mounting plate, with floating baffles installed at both ends of the U-shaped mounting plate, and a through hole provided in the middle of the floating baffle. The front and rear floating components pass through the through hole of the floating baffle and are mounted on the U-shaped mounting plate.

[0013] Preferably, linear bearings are provided on both sides of the floating slider, and a first compression spring is sleeved between the linear bearings and the two side walls of the floating mechanism mounting plate.

[0014] Preferably, the front and rear floating components include at least one telescopic connecting rod, and a second compression spring is sleeved on the outer peripheral wall of each of the at least one telescopic connecting rod. One end of the at least one telescopic connecting rod is connected to the adaptive connecting component, and the ends of the two telescopic connecting rods away from the adaptive connecting component pass through the through hole of the floating cover and are rigidly connected to the mounting base.

[0015] Preferably, the adaptive connection assembly includes a front flexible connection plate, a rear flexible connection plate, and a buffer. The front flexible connection plate and the rear flexible connection plate are connected by the buffer. The rear flexible connection plate is connected to two telescopic connection rods. The front flexible connection plate is connected to the male connector assembly of the charging pile.

[0016] Preferably, the buffer is a flexible rubber component.

[0017] Preferably, pulleys are provided on both sides of the end of the male charging pile assembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] When docking with an AGV for charging, the system improves the ability to correct deviations, making the docking smoother. When a deviation occurs during docking, the adaptive connection component first absorbs the impact from the AGV and then transfers it to the front-to-back floating component and the left-to-right floating component. These components then buffer and dampen the impact on the front-to-back and left-to-right sides, respectively, thus improving the ability to correct deviations. Attached Figure Description

[0030] Example:

[0031] like Figure 1-2As shown, this embodiment provides an adaptive charging floating mechanism, including a left and right floating component 4, a front and rear floating component 3 is provided on the side of the left and right floating component 4, an adaptive connecting component 2 is provided at the end of the front and rear floating component 3, a charging pile male connector component 1 is provided at the end of the adaptive connecting component 2, and pulleys are provided on both sides of the end of the charging pile male connector component 1.

[0032] like Figure 3 As shown, the left and right floating components 4 include a rectangular plate-shaped floating shield 4-1. A through hole is provided through the center of the floating shield 4-1. A floating mechanism mounting plate 4-2 is provided on one side of the floating shield 4-1. The floating mechanism mounting plate 4-2 is a U-shaped plate structure. Two optical axes 4-5 are provided between the two side walls of the floating mechanism mounting plate 4-2. Left and right floating sliders 4-4 are sleeved on the two optical axes 4-5. The left and right floating sliders 4-4 are hollow rectangular blocks, and linear bearings 4-6 are provided on both sides of each slider. Four first compression springs 4-3 are sleeved on the two optical axes 4-5. They are respectively provided between the two linear bearings 4-6 and the two side walls of the floating mechanism mounting plate 4-2. The two optical axes 4-5 are located on the same vertical plane and are distributed one above the other. The floating shield 4-1 is located on the side closer to the floating slider and is fixedly connected to the floating slider.

[0033] The front and rear floating components 3 include two telescopic connecting rods. A second compression spring 4-3 is sleeved on the outer peripheral wall of the two telescopic connecting rods. One end of the two telescopic connecting rods is connected to the adaptive connecting component 2. The end of the two telescopic connecting rods away from the adaptive connecting component 2 passes through the through hole of the moving cover plate and is connected to the mounting base.

[0034] like Figure 4 As shown, the adaptive connection component 2 includes a front flexible connection plate 2-1, a rear flexible connection plate 2-3, and a rubber flexible component 2-2. The front flexible connection plate 2-1 and the rear flexible connection plate 2-3 are connected by the rubber flexible component 2-2. The rear flexible connection plate 2-3 is connected to two telescopic connection rods. The front flexible connection plate 2-1 is connected to the male connector component 1 of the charging pile. The rubber flexible component 2-2 is a galvanized metal part with environmentally friendly materials inside and selected rubber material on the outside. It has high elasticity, high strength, and excellent shock absorption and buffering effect.

[0035] like Figure 5 The diagram shown is a schematic of the adaptive charging floating mechanism provided in this embodiment installed on a charging pile. Its working principle is as follows:

[0036] After precise measurement, the charging interface on the AGV and the male connector assembly 1 of the charging pile are set at the same height. When the AGV needs to perform a charging operation, the AGV drives itself to the charging pile. As the AGV charging interface gets closer to the male connector assembly 1, uneven ground may cause a deviation in the left and right directions between the AGV charging interface and the male connector assembly 1. At this time, one side of the male connector assembly enters the charging interface, while the other side is blocked. The AGV continues to move and triggers the adaptive connection component 2 and the front and rear floating components 3. The adaptive connection component 2 and the front and rear floating components 3 provide elastic buffer for the blocked side. At the same time, the pulley at the end of the male connector assembly 1 (the pulley on one side inside the charging interface) slides along the charging interface, which can drive the left and right floating components 4 to make fine adjustments in the left and right directions, realize the correction of the left and right deviation, complete the fit between the male connector assembly 1 and the AGV charging interface, and thus protect the charging pile and the AGV charging components.

[0037] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described.
