[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] A specific embodiment of this utility model provides a novel AGV for automotive chassis assembly lines, combined with attached... Figure 1-3As shown, the main components include a frame body 1, a drive mechanism, a swing mechanism 8, a lifting device 9, and an electrical control mechanism. The frame body 1 is a rectangular frame, with several support rods 2 arranged in a "well" shape inside, and its open spaces are used for the installation of various equipment. The drive mechanism includes a first drive group 3, a second drive group 4, a third drive group 5, and a fourth drive group 6, which are located at the four corners of the frame body 1. There is a gap between the first drive group 3, the second drive group 4, and the frame body 1. The first drive group 3 and the second drive group 4 are connected by a crossbeam 7. The swing mechanism 8 is located at the center between the frame body 1 and the crossbeam 7, and is bolted to the frame body 1 and the crossbeam 7. The lifting device 9 is located between the frame bodies 1 and is bolted to the support rods 2. The electrical control mechanism includes a battery 10 and a control panel, which is built into a control box 11 located on the side of the frame body 1. The battery 10 is electrically connected to the drive mechanism and the control panel.

[0033] Specifically, the first drive group 3, the second drive group 4, the third drive group 5, and the fourth drive group 6 are all equipped with a base AGV 12 and a support column 13. The base AGV 12 is equipped with a drive unit 121, a protective radar 122, and a clearing brush 123. The drive unit 121 is located inside the bottom of the base AGV 12 and is in contact with the ground, which can drive the equipment to move and turn. The protective radar 122 is located on the outer side of the base AGV 12 and can receive the position information of the road surface or objects within the detection range. This information can be transmitted to the control panel for system processing via electrical signals. The processed information is then transmitted to the base AGV 12 via electrical signals to prevent the base AGV 12 from colliding during movement or turning. The clearing brush 123 is located on the bottom outer side of the base AGV 12 and can clean up road debris during the movement of the base AGV 12, preventing debris from being rolled into the drive unit 121 and causing uneven driving.

[0034] Specifically, the support column 13 and the top of the base AGV 12 are vertically connected and fixed. An emergency stop button 132 and an indicator light 133 are provided on one side of the support column 13. The indicator light 133 is located above the emergency stop button 132. The emergency stop button 132 can be used to stop the operation of the base AGV 12 in an emergency. The indicator light 133 uses different bright colors to indicate the operating status of the base AGV 12. If the indicator light 133 shows blue, it means that the base AGV 12 is operating normally without fault. If the indicator light 133 shows red, it means that the base AGV 12 is not operating normally and has a fault. The emergency stop button 132 needs to be activated to stop the operation of the base AGV 12 and carry out maintenance. An HMI panel 131 is provided on the support column 13 of the third drive group 5. The HMI panel 131 is a touch panel used to display the real-time operating status of the equipment and can realize touch operation.

[0035] Specifically, such as Figure 4 and Figure 5 As shown, the support columns 13 of the first drive group 3 and the second drive group 4 are located on the same side of the bottom of the frame body 1 and are connected by a crossbeam 7. A swing mechanism 8 is set at the center between the crossbeam 7 and the crossbar on the side of the frame body 1. A floating space A is set between the top of the two support columns 13 and the bottom of the frame body 1. The crossbar 7 makes lever movement with the swing mechanism 8 as the base point. The support columns 13 of the first drive group 3 and the second drive group 4 at both ends of the crossbar 7 can float up and down. When the base AGV encounters an uneven road surface, a height difference is generated during the movement. The support columns 13 move up or down, driving the crossbar 7. The crossbar 7 swings with the swing mechanism 8 as the base point to ensure that the frame body 1 and the ground remain parallel.

[0036] Specifically, such as Figure 5 As shown, two sets of anti-bending arms 14 are provided at both ends of the frame body 1 and the crossbar 7. In this embodiment, the anti-bending arms 14 include a transmission frame 141 and several universal ball bearings 142. The transmission frame 141 is divided into an upper part and a lower part. The upper part is set as a cubic hollow frame. The side of the frame body 1 is set in the cubic hollow frame. The universal ball bearings 142 pass through the cubic hollow frame, and the spherical surface of the universal ball bearings 142 is in close contact with the side of the frame body 1. The lower part of the transmission frame 141 is bolted to the crossbar 7. If a collision occurs during the movement of the base AGV12, the resistance is transmitted from the support column to the frame body 1. If the frame body 1 is subjected to this resistance, it will affect the adjustment shaft 81 of the swing mechanism. Therefore, the resistance is transmitted to the crossbeam 7 through the universal ball bearings 142 of the transmission frame 141, reducing the resistance of the shaft 81 of the swing mechanism 8 and improving the durability of the equipment.

[0037] Specifically, an integrated industrial control computer 15 is symmetrically arranged on both sides of the main frame 1. The integrated industrial control computer 15 is connected to the control panel, the hoist 9, the air supply equipment 16 and the lighting equipment 17, and is used to control the start and stop of each device and display real-time information through software. The integrated industrial control computer 15 is set in a vertical position, which is convenient for workers at the workstation to observe and operate. The air supply equipment 16 and the lighting equipment 17 are set on the inner side of the main frame 1, and the lighting equipment 17 is set above the air supply equipment 16, providing air supply and lighting for the workstation respectively.

[0038] The advantage of this embodiment is that:

[0039] This embodiment of the equipment is a novel conveying carrier proposed for automobile chassis assembly lines. The AGV features a novel structure, consisting of four sets of driven support columns and a top frame, and is equipped with a lifting device for transporting vehicle bodies. Two sets of support columns are connected to a swinging structure, allowing the AGV to swing around a hinge point relative to the top frame to adapt to uneven ground. It also includes a ventilation system, lighting system, and an integrated industrial control unit. This equipment eliminates the need for steel structure installation and has no requirements on factory load-bearing capacity, reducing steel structure costs, factory construction costs, and on-site construction time. Furthermore, this conveying method offers significant flexibility, greatly facilitating future line modifications.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
