[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] like Figure 1-14 As shown, the lightweight multifunctional intelligent AGV of the present invention comprises a walking unit 2 and a carrier unit 1 installed above the walking unit 2, wherein the walking unit and the carrier unit are detachable; wherein the carrier unit comprises a push module 3 and a cargo receiving roller module 4, wherein the push module comprises a frame-type push rod, two linear guides 17 for horizontal movement of the push rod, the linear guides are connected to a slider 16, the slider 16 is fixed to the bottom of the push rod, a screw rod 15 and a screw motor 20 for driving the horizontal reciprocating movement of the push rod, the screw motor 20 is installed on the chassis of the trolley, and is connected to the screw rod 15 through a gear rack, specifically, an output gear 22 is installed on the output shaft of the screw motor, and is connected to the gear 23 on the screw rod through a chain (not shown). When goods are placed on the carrier unit, the goods are sent out or received through the cooperation of the push module and the receiving rollers of the cargo receiving roller module 4.

[0033] Preferably, the push rod is a frame structure, fixedly connected to the slider on the linear guide rail, the screw rod is arranged between the two linear guide rails, and is transmission-connected to the screw motor arranged on one side to realize the reciprocating movement of the push rod.

[0034] Specifically, the push rod 3 includes a cylindrical rod at the upper end and two vertical plates connected to the two ends of the cylindrical rod. The bottom of the vertical plate is rotatably connected to the base body connected to the screw nut and can be rotated 90 degrees to achieve uprightness or horizontal placement.

[0035] A driving arm 12 is arranged on the outer side of the vertical plate, and a matching guide rail 13 (guide groove) is arranged on the outer side of the driving arm. The driving arm cooperates with the guide rail to control the rotation of the vertical plate when the driving arm enters and exits the guide groove of the guide rail, so that the push rod stands up vertically or falls down horizontally.

[0036] Among them, the pushing rod 3 is driven by the screw rod to move forward horizontally. When the connected driving arm 12 is separated from the guide rail 13, it will fall down by gravity, so that the goods can be completely pushed out of the trolley. When it returns to the initial position, it enters the guide rail 13 through the driving arm, and utilizes the special shape of the guide rail to change from a horizontal state to an upright state.

[0037] The cargo receiving roller module includes two groups of receiving rollers, which are symmetrically arranged on both sides of the push module to form two groups, and cooperate with the push module to realize the receiving and delivery of cargo. When receiving cargo, the receiving rollers rotate counterclockwise, and the push rod is at the far left. When sending cargo out, the receiving rollers rotate clockwise, and the push rod moves horizontally to the right to push the cargo out together.

[0038] Preferably, the pick-up rollers are driven to rotate by a motor, such as through a chain and gear transmission mechanism, and the drive motor rotates forward and reversely to realize the pick-up and delivery of goods. Specifically, the plurality of pick-up rollers arranged in parallel are equipped with gears 14 and chains (not shown) at the ends to form a synchronous transmission connection structure, and one pick-up roller is connected to a gear 19 (arranged at both ends) on the drive shaft of the drive motor 18 on the chassis of the trolley through a chain, thereby forming a transmission structure to realize the synchronous rotation of the pick-up rollers to transport goods.

[0039] Wherein, the gear transmission mechanism and the corresponding driving motor are placed on the trolley chassis of the walking unit.

[0040] Furthermore, the three upper side surfaces of the carrier unit form limiting vertical frames, and the other side is open to form a cargo entrance and exit.

[0041] Furthermore, a plurality of supporting connectors 24 are provided on the chassis of the walking unit, and the supporting connectors are connected to the carrier unit by fasteners and are detachable.

[0042] Preferably, the supporting connecting member is an L-shaped member, which is in multiple numbers and symmetrically arranged to form two groups, and is respectively fixedly connected to the chassis of the carrier unit by bolts.

[0043] In the present invention, the walking unit adopts a two-wheel differential drive trolley chassis, including a floating differential shock-absorbing wheel assembly 5, a load-bearing universal wheel 6, an identification module 9, a central processing unit 8, a battery pack 7, and a laser radar 10, which are installed on the rectangular shape of the walking unit.

[0044] There are four load-bearing universal wheels 6 arranged near the four corners, two floating differential damping wheel assemblies arranged symmetrically, including differential drive wheels and damping springs 20, etc., the battery pack 7 supplies power to the electrical equipment, the identification module 8 includes a camera for identifying the two-dimensional code coordinate signal on the ground, so as to determine the position of the AGV according to the identified signal (correspondingly, a avoidance hole is provided on the chassis of the trolley, so that the signal identification module 8 can scan and identify the two-dimensional code mark on the ground), and two laser radars 10 are arranged symmetrically for identifying the faults on the road surface of the trolley. Correspondingly, avoidance holes are formed on the chassis of the trolley, so that the laser radar 10 can identify whether there is a roadblock on the ground. The central processor 7 is used to determine the position of the trolley according to the identification of the identification module, and determine whether there is a roadblock according to the signal of the laser radar, so as to control the trolley to move forward to the corresponding position. When there is a roadblock, the alarm stops, and the trolley moves forward again after the roadblock is cleared, and the moving distance is controlled according to the two-dimensional code mark.

[0045] It should be noted that, in the present invention, the walking unit may also be implemented by using the walking mechanism of an existing AGV vehicle, and is not limited to the above-mentioned embodiment.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
