[0039] like Figure 1-7 As shown, this utility model provides a quick connection mechanism for loading racks on AGVs, which includes: multiple connecting structure units 100, which are respectively embedded in the housing 200 of the AGV chassis.

[0040] The connecting structure unit 100 mainly includes: bracket 110, connecting rod 120, motor 130, turntable 140, pressure column 150 and drive connecting plate 160.

[0041] The bracket 110 is disposed within the housing 200 of the AGV chassis, and the bottom of the bracket 100 is fixedly connected to the vehicle frame (not shown in the figure); wherein the vehicle frame is disposed within the housing 200. The top of the bracket 100 abuts against the inner wall of the top plate of the housing 200 of the AGV chassis.

[0042] The connecting rod 120 is perpendicular to the top plate of the housing 200. The lower end of the connecting rod 120 is connected to the bottom of the bracket 110 via a spring 121, and the upper end can axially move through the top of the bracket 110. The top plate of the housing 200 has a through hole 201 corresponding to the connecting rod 120, allowing the connecting rod 120 to move from the through hole 201 to above the top plate of the housing 200. The AGV upper loading rack (not shown in the figure) has a groove matching the connecting rod 120. The connecting rod 120 can rise and insert into the groove of the AGV upper loading rack to connect with it, thereby enabling the AGV upper loading rack to be mounted on the AGV chassis (housing 200).

[0043] The motor 130 is fixedly mounted on the bracket 110, and the output shaft of the motor 130 is parallel to the top plate of the housing 200. The turntable 140 is coaxially fixedly connected to the output shaft of the motor 130; the pressure column 150 is cylindrical, with one end connected to the turntable 140 and positioned near the edge of the turntable 140; the axis of the pressure column 150 is arranged along the axial direction of the turntable 140. A drive connecting plate 160 is provided on the connecting rod 120, and the cylindrical surface of the pressure column 150 contacts the upper surface of the drive connecting plate 160; when the motor 130 rotates, it can drive the drive connecting plate 160 to move up and down through the pressure column 150, causing the connecting rod 120 to extend above the top plate of the housing 200 or retract into the housing 200.

[0044] As a preferred embodiment, the pressure column 150 is rotatably connected to the turntable 140, so that the cylindrical surface of the pressure column 150 can rotate relative to the drive connecting plate 160, making the movement of the connecting column 120 smoother.

[0045] In this embodiment, a guide sleeve 170 is installed on the bracket 110, and the connecting rod 120 is coaxially matched and installed in the guide sleeve 170. By installing the guide sleeve 170, the linear movement of the connecting rod 120 can be guaranteed, and the deviation of the connecting rod 120 during movement can be avoided.

[0046] In this embodiment, the support 110 includes: a first flat plate 111, a second flat plate 112, a first upright plate 113, and a second upright plate 114.

[0047] The first plate 111 and the second plate 112 are spaced apart and are both parallel to the top plate of the housing 200. The first plate 111 abuts against the inner wall of the top plate of the housing 200, and the second plate 112 is fixedly connected to the frame. The first upright plate 113 and the second upright plate 114 are symmetrically fixedly connected between the first plate 111 and the second plate 112, and the first plate 111 and the second plate 112 are both perpendicular to the top plate of the housing. The first plate 111, the second plate 112, the first upright plate 113 and the second upright plate 114 form a rectangular frame structure. In this embodiment, the first plate 111, the first upright plate 113 and the second upright plate 114 are integrally formed structures, and the first plate 111, the first upright plate 113 and the second upright plate 114 form a U-shaped structure (opening downwards). The lower ends of the first upright plate 113 and the second upright plate 114 are respectively fixed to the second plate 112 by bolts.

[0048] The motor 130 is fixedly installed on the outside of the first upright plate 113, and the output shaft of the motor 130 is rotatably extended through the first upright plate 113 to the space between the first upright plate 113 and the second upright plate 114.

[0049] A first flange 122 is provided at one end (lower end) of the connecting rod 120, and the drive connecting plate 160 is fixedly connected to the first flange 122.

[0050] The lower end of the connecting rod 120, which connects to the first flange 122, has an axially oriented groove 123. The upper end of the spring 121 extends into the groove 123 and connects to the connecting rod 120. A spring guide post 112a is fixedly mounted on the second plate 112. The spring guide post 112a is coaxially arranged with the connecting rod 120, and the lower end of the spring 121 is sleeved on the spring guide post 112a.

[0051] A second flange 171 is provided on the top of the guide sleeve 170, and the guide sleeve 170 is fixed to the first plate 111 through the second flange 171. The top of the first plate 111 is provided with a guide hole 111a, through which the main body of the guide sleeve 170 passes. The size of the second flange 171 is larger than the size of the guide hole 111a. The second flange 171 is located on the first plate 111 and is fixedly connected to the first plate 111 by bolts.

[0052] In this embodiment, the second flange 171 is embedded in the through hole 201, and the upper surface of the second flange 171 is flush with the upper surface of the housing 200.

[0053] A long through groove 114a is provided on the second upright plate 114 along the axial direction of the connecting rod 120, and a measuring rod 161 is fixedly connected to one end of the drive connecting plate 160. The measuring rod 161 passes through the long through groove 114a and extends to the outside of the second upright plate 114.

[0054] Two photoelectric sensors 180 are fixed on the outer side of the second upright plate 114 and are respectively set near the two ends of the long through groove 114a to detect the position of the measuring rod 161.

[0055] Preferably, the photoelectric sensor 180 is a slot-type photoelectric sensor. When one end of the positioning rod 161 passes through the photoelectric slot of the photoelectric sensor 180, the position of the positioning rod 161 is determined. Thus, the lifting height of the connecting rod 120 is determined based on the position of the positioning rod 161.

[0056] As a preferred embodiment, the second upright plate 114 has a guide groove 114b, the length of which is aligned with the axial direction of the connecting rod 120. A guide roller 190 is mounted on the drive connecting plate 160, the guide roller 190 being disposed within the guide groove 114b and capable of moving along its length. The guide roller 190 employs a roller bearing, the outer circumference of which contacts the guide groove 114b; as the guide groove 114b moves, the guide roller 190 rolls relative to it, thereby ensuring the stability of the drive connecting plate 160's movement.

[0057] like Figure 1-2 As shown, in this embodiment, four connecting structural units 100 are provided, respectively located near the four apex corners of the AGV chassis housing; correspondingly, four grooves are provided on the rack (bottom) to correspond one-to-one with the connecting rods 120 of the connecting structural units 100. A stable connection between the rack and the chassis can be achieved through the four connecting structural units 100.

[0058] During use, if the rack is not to be installed, the motor 130 drives the connecting rod 120 to move to the lower stop point (near the photoelectric sensor 180 at the lower end of the long through groove 114a) via the turntable 140 and the pressure column 150. This causes the connecting rod to retract into the housing 200 (guide sleeve 170), ensuring that the connecting rod 120 does not exceed the chassis surface and does not affect the goods directly placed on the chassis. During the descent of the connecting rod 120, the spring 121 is in a compressed state. If the rack needs to be installed, the rack is placed on the AGV chassis. After positioning, the motor 130 drives the turntable 140 to rotate, causing the pressure column 150 to move upward. Under the restoring force of the spring 121, the connecting rod 120 rises to the upper stop point (near the photoelectric sensor 180 at the upper end of the long through groove 114a) and enters the corresponding groove in the rack, thus connecting and fixing it to the rack.

[0059] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
