The ratchet wheel 301 is meshed with each other, thereby fixing the ratchet wheel 301, preventing the ratchet wheel 301 from rotating counterclockwise and causing the flow-receiving slide plate 103 to slide out. When the flow-receiving slide plate 103 needs to be disassembled again, the paddle 3021 is pushed outward to drive the pawl 302 to disengage from the ratchet wheel 301, thereby realizing the counterclockwise rotation of the rotating rod 204, and then through the meshing between the ratchet wheel 301 and the pawl 302 in the locking assembly 3, the baffle 201 is automatically locked and fixed to the flow-receiving slide plate 103 after limiting the position, thereby ensuring the stability of the baffle 201 after closing.

[0029] Reference Figure 1-7 , the mounting frame 102 is provided with three, and a buffer assembly 4 is installed between two adjacent mounting frames 102, and the buffer assembly 4 includes a first movable rod 401, one end of the first movable rod 401 is rotatably connected to one mounting frame 102, the other end of the first movable rod 401 is rotatably connected to the second movable rod 402, and the end of the second movable rod 402 away from the first movable rod 401 is rotatably connected to the other mounting frame 102, the first movable rod 401 and the second movable rod 402 are equal in length, and the tops of the first movable rod 401 and the second movable rod 402 are both provided with a limiting slide groove 403, and a slider 404 is slidably connected inside the limiting slide groove 403, and a stabilizing rod 405 is rotatably connected between the two sliders 404, and a compression spring 406 is elastically connected between the limiting slide groove 403 and the slider 404, and a limiting block 407 is fixedly provided at the bottom of the slider 404, and the cross section of the limiting block 407 is T-shaped, and a limiting groove 4071 for the limiting block 407 to slide is provided inside the first movable rod 401; When the APM vehicle is impacted, the first movable rod 401 and the second movable rod 402 are brought closer together, driving the stabilizing rod 405 and the slider 404 to slide upward inside the limiting slide groove 403, and compressing the compression spring 406 to deformation, so as to buffer a certain impact force, and then through the compression of the compression spring 406 by the limiting slide groove 403 in the buffer assembly 4, the impact force on the flow receiving slide plate 103 when the APM vehicle is impacted is effectively reduced, thereby improving the stability of the flow receiving slide plate 103 when in contact with the track, and ensuring the quality of flow receiving.

[0030] Working principle: First, when installing the current collecting slide plate 103, place the current collecting slide plate 103 inside the mounting frame 102, and then limit the two ends and one side of the current collecting slide plate 103 through the mounting frame 102, and then manually rotate the turntable 2041 clockwise, and the rotation of the turntable 2041 drives the rotating rod 204, the third gear 2042, the first gear 2032, the second gear 20331 and the second bevel gear 20332 to rotate in turn, and the transmission between the second bevel gear 20332 and the first bevel gear 202 drives the first bevel gear 20331 to rotate. 02. The rotating shaft 2011 and the baffle plate 201 are rotated toward the position of the flow receiving slide plate 103 until one side of the baffle plate 201 is abutted against one side of the flow receiving slide plate 103, so that the flow receiving slide plate 103 can be installed. Then, the turntable 2041 in the installation mechanism 2 transmits the third gear 2042, so that the baffle plate 201 can be automatically opened and closed and the flow receiving slide plate 103 can be limited, thereby realizing the rapid installation and disassembly of the flow receiving slide plate 103, reducing the labor intensity of the staff when frequently replacing the flow receiving slide plate, and improving the efficiency of replacing the flow receiving slide plate.

[0031] Then, when the baffle 201 is automatically locked, as the baffle 201 gradually closes to the position of the current receiving slide 103, as the rotating rod 204 rotates clockwise, the ratchet 301 is synchronously driven to rotate clockwise, and through the meshing between the ratchet 301 and the pawl 302, when the ratchet 301 rotates, the pawl 302 is driven to swing in place, and the pawl 302 is reset by the reset spring 303, and this is repeated until the baffle 201 is completely in contact with the current receiving slide 103, and the pawl 302 is again engaged with the ratchet 301. The ratchet 301 is engaged with each other, thereby fixing the ratchet 301, preventing the ratchet 301 from rotating counterclockwise and causing the flow-receiving slide 103 to slide out. When the flow-receiving slide 103 needs to be disassembled again, the paddle 3021 is pushed outward to drive the pawl 302 to disengage from the ratchet 301, thereby realizing the counterclockwise rotation of the rotating rod 204, and then through the engagement between the ratchet 301 and the pawl 302 in the locking assembly 3, the baffle 201 is automatically locked and fixed to the flow-receiving slide 103 after limiting the position, thereby ensuring the stability of the baffle 201 after closing.

[0032] Finally, when the APM vehicle has an impact, the first movable rod 401 and the second movable rod 402 are brought closer together, driving the stabilizing rod 405 and the slider 404 to slide upward inside the limiting slide groove 403, and compressing the compression spring 406 to deformation, thereby buffering a certain impact force, and then through the compression of the compression spring 406 by the limiting slide groove 403 in the buffer assembly 4, the impact force on the flow receiving slide plate 103 when the APM vehicle has an impact is effectively reduced, thereby improving the stability of the flow receiving slide plate 103 when it contacts the track and ensuring the quality of flow receiving.
