[0025] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The present application embodiment discloses a concave explosion-proof AGV body structure, such as Figure 1 As shown, it includes a vehicle body 1.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a groove is provided in the middle of the upper surface of the vehicle body 1, so that the vehicle body 1 forms a concave structure in the middle. Such a structure can reduce the center of mass height when loading products, so that the operation can be more stable. A drive unit mounting plate 5 is provided inside the vehicle body, and the drive unit mounting plate 5 is used to install the wheel set 8. The wheel set 8 is placed on both sides of the vehicle body 1, so that a large diameter wheel set can be placed, and patterned steel plates are added on both sides of the upper surface of the vehicle body 1 as a platform, which makes it more convenient for workers to operate.

[0028] The vehicle body 1 forms a platform at both sides of the groove, and the platform surface can be used as a working platform for workers after being covered with patterned steel plates. The platform position of the vehicle body 1 is formed by a platform bracket 4, and the platform bracket 4 is connected to a drive unit mounting plate 5, and a wheel set 8 is rotatably connected to the drive unit mounting plate 5.

[0029] like Figure 2 and Figure 4As shown, in order to bear the load, a crossbeam 2 is fixed at the bottom of the groove of the vehicle body 1, and a linear guide 16 is fixed on the crossbeam. The posture adjustment mechanism is slidably connected with the linear guide 16, so that the posture adjustment mechanism can move along the linear guide 16 on the vehicle body 1. The vehicle body 1 is provided with an installation groove downward at the bottom of the groove, and an explosion-proof partition 7 is arranged at the bottom and around the installation groove to play an explosion-proof role. An electric control unit installation plate 6 is arranged in the installation groove, and the electric control unit installation plate 6 is arranged inside the space formed by the explosion-proof partition 7. The electric control unit installation plate 6 is provided with installation holes for installing the electric control unit 14, and these installation holes can also serve as heat dissipation. A cover plate 3 is installed at the bottom of the groove of the vehicle body 1, and the cover plate 3 covers the top opening of the installation groove.

[0030] A tilt sensor 9 is arranged on one side of the upper surface of the vehicle body 1 to measure the levelness of the entire vehicle body.

[0031] like Figure 5 As shown, four sets of lifting foot assemblies 10 are arranged at the four corners of the bottom of the vehicle body 1, which can automatically level the vehicle body. The lifting foot assembly 10 includes a lifting foot 10-1, a connecting plate 10-2, a pressure sensor 10-3, a floating ball head 10-4 and a floating support 10-5; the lifting foot 10-1 includes a frame and an extension rod, the frame is fixedly connected to the connecting plate 10-2, the frame is connected to the vehicle body 1 through the connecting plate 10-2, one end of the extension rod extends into the frame, and the extension rod is slidably connected to the frame, and the other end of the extension rod is fixedly connected to the pressure sensor 10-3. The floating ball head 10-4 includes a mounting portion and a ball head, the ball head is fixedly connected to the mounting portion, and the mounting portion is fixedly connected to the side of the pressure sensor 10-3 away from the extension rod. One end of the floating support 10-5 is provided with a ball socket, and the other end is a flared cone in a direction away from the ball socket. The ball head of the floating ball head 10-4 is placed in the ball socket of the floating support 10-5. The floating ball head 10-4 rotates in the ball socket to adapt to small angle adjustments. The flared cone end of the floating support 10-5 is used to contact the ground.

[0032] Before the AGV performs high-precision work, the motor controls the legs to extend. When the legs touch the ground, the floating support can adapt to uneven ground. The horizontal state of the vehicle body is measured by the inclination sensor and the data is fed back to the electronic control system. The control system controls each leg to adjust the telescopic height so that the vehicle body reaches a level state. At this time, the pressure sensor transmits data to the control system to confirm that each leg is in a compacted stress state. If the force on the leg pressure sensor is 0, the control system controls the leg to continue to extend, and the inclination sensor continues to work until it is leveled. Through the leveling system, the leveling accuracy can reach 0.05mm.

[0033] In summary, this patent considers lowering the center of mass height when carrying products when laying out the vehicle body, so it is designed into a concave structure, so that both sides can meet the needs of installing large-diameter wheel assemblies and can also be used as working platforms for workers. In order to be more suitable for workers to work, patterned steel plates are laid on the working platforms on both sides, which can improve safety during work;

[0034] Make full use of the vehicle body structure and set the platform bracket 4, which is both a wheel assembly mounting bracket and a platform load-bearing structure; after laying the patterned steel plate, it becomes the platform 1, which can be used as a working platform for workers to increase safety during work; the vehicle body direction reinforcement ribs are machined into a plane, which can be used for laying guide rails and racks;

[0035] The bottom of the entire concave frame of the vehicle body is set as an explosion-proof control box through an explosion-proof partition 7. Through the structural design that meets the explosion-proof requirements, the drive unit mounting plate 5 and the electronic control unit mounting plate 6 are set, and the controller mounting hole is opened to form a whole explosion-proof control box, which saves the box space. The explosion-proof partition 7 can also be used as a vehicle body reinforcement rib to increase the strength of the vehicle body.
