[0005] To address the shortcomings of existing technologies, this utility model provides an AGV vehicle charging control mechanism that solves the problem of inconvenience in protecting the charging brush when charging stops, making the charging brush susceptible to damage from impacts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an AGV vehicle charging control mechanism, including a charging pile, a drive motor connected to the bottom of the charging pile, a drive shaft connected to the output shaft of the drive motor, an active cone wheel connected to one end of the drive shaft, two driven cone wheels connected to the surface of the active cone wheel, and a lead screw connected to the side of the two driven cone wheels that are far apart from each other;

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 In one embodiment of this utility model, an AGV vehicle charging control mechanism includes a charging pile 1, a drive motor 2 connected to the bottom of the charging pile 1, a drive shaft 3 connected to the output shaft of the drive motor 2, an active cone wheel 4 connected to one end of the drive shaft 3, two driven cone wheels 5 connected to the surface of the active cone wheel 4, and a lead screw 6 connected to the side of the two driven cone wheels 5 that are far apart from each other.

[0024] The specific problem addressed by this embodiment is to solve the issue of inconvenience in protecting the charging brush when charging is stopped, making the charging brush susceptible to damage from impacts. This invention utilizes an active conical wheel 4 and a driven conical wheel 5 for driving, a cylindrical gear 13 for rotation, and a protective plate 9 and a protective block 16 for shielding, achieving automatic protection and automatic opening functions. Ultimately, this solves the problem of damage easily caused by impacts and effectively improves safety during use.

[0025] A support rod 7 is connected to the surface of the lead screw 6, a support shaft 8 is connected to the top of the support rod 7, a protective plate 9 is connected to the surface of the support shaft 8, a protective block 16 that cooperates with the charging brush on the surface of the charging pile 1 is connected to the inner surface of the protective plate 9, a slider 10 and a cylindrical gear 13 are connected to the top of the support shaft 8 through the protective plate 9, a fixing rod 11 is connected to the inner wall of the slider 10, and a support block 12 is connected to one end of the fixing rod 11 that is far apart from each other. In this specific embodiment, a support frame 14 is connected to the surface of the charging pile 1 outside the cylindrical gear 13, and two equally spaced tooth blocks 15 are provided on the inner wall of the support frame 14, which cooperate with the cylindrical gear 13. The protective plate 9 and protective block 16 provided by this utility model can effectively shield the charging brush, thereby protecting the charging brush when charging stops. This effectively solves the problem of the charging brush being damaged by collisions with external objects. Furthermore, the protective plate 9 is driven to slide by the lead screw 6 and rotated by the cylindrical gear 13, which automatically opens the charging brush, improving the convenience of operation. After being rotated, the protective plate 9 can be used for clamping and positioning during the charging process of the AGV vehicle, improving the stability of the AGV vehicle charging and solving the problem of disconnection caused by shaking during the charging of the AGV vehicle.

[0026] In this specific embodiment, a gap is provided between the tooth blocks 15, and the gap is greater than the gap between the two cylindrical gears 13;

[0027] By setting the spacing to be greater than the spacing between the two cylindrical gears 13, the cylindrical gears 13 will not rotate during the initial sliding, so that the protective plate 9 can move the protective block 16 away from the charging brush before the flipping function is realized.

[0028] In this specific embodiment, the fixing rod 11 has a smooth surface, and the slider 10 is slidably connected to the fixing rod 11;

[0029] By using a smooth surface, the fixing rod 11 can effectively guide the sliding of the slider 10.

[0030] In this specific embodiment, the support frame 14 is distributed in a "C" shape, and the inner walls of both ends of the support frame 14 are provided with a distance from the two side surfaces of the charging pile 1.

[0031] The support frame 14 has a distance between its inner walls at both ends and the two side surfaces of the charging pile 1, allowing the protective plate 9 to slide to the outermost sides of the charging pile 1 while still ensuring the flipping operation.

[0032] In this specific embodiment, the threads on the outer walls of the two lead screws 6 are distributed in the same direction, and the support rod 7 is threadedly connected to the lead screw 6 through a nut provided on the inner wall;

[0033] The threads on the outer walls of the two lead screws 6 are distributed in the same direction, so that when the driving cone wheel 4 drives the two driven cone wheels 5 to rotate in opposite directions, the lead screws 6 with the same thread drive the support rods 7 to slide in opposite directions or in opposite directions.

[0034] Working principle: The drive motor 2 drives the drive shaft 3 to rotate, which in turn drives the active cone wheel 4 to rotate. The active cone wheel 4 drives the two driven cone wheels 5 to rotate in opposite directions. The two driven cone wheels 5 drive the support rod 7 to slide in opposite directions via the lead screw 6. The support rod 7 drives the protective plate 9 to slide in opposite directions via the support shaft 8. The protective plate 9 drives the protective block 16 to release the protection of the charging brush. After the protective plate 9 slides a certain distance, the cylindrical gear 13 will contact the tooth block 15. The cylindrical gear 13 will slide and rotate at the same time, thereby driving the protective plate 9 to flip through the support shaft 8. When the two protective plates 9 are flipped to 90°, they will be parallel to each other, which can clamp and position the AGV vehicle during charging, thereby improving the stability of the AGV vehicle during charging.
