[0035] With the above structure, the bottom plate 41, the top plate 42 and the two side plates 43 are used to form a cavity structure, and the strength is enhanced by the reinforcing plate 44, so the overall structural strength is high.

[0036] With the above structure, the bottom plate 41, the top plate 42, the side plate 43 and the reinforcing plate can all be made by milling or die-casting, with low single processing cost and conducive to mass production. They are fixed with bolts and have high assembly efficiency.

[0037] In order to realize that the frame structure can realize the steering of the load in the load scenario, such as Figure 1 , 2 As shown in FIG. 4 , the component mounting hole includes a first mounting hole 451 disposed on the top plate 42 for mounting the drive motor, and the frame structure also includes a rotating plate 46 disposed above the first mounting hole.

[0038] Since the first mounting hole 451 is disposed on the top plate, in order to achieve waterproofing and protect the components in the frame, the top plate 42 and the rotating plate 46 are provided with a circle of first grooves 471 for accommodating needle bearings and at least one circle of second grooves 472 for accommodating sealing rings around the first mounting hole 451.

[0039] The second groove 472 can be provided with one circle or two circles. When provided with one circle, the second groove 472 is provided outside the first groove 471. In order to further improve the waterproof performance, the second groove 472 is preferably provided with two circles, and is respectively provided inside and outside the first groove 471.

[0040] In order to facilitate the detection of the rotation angle of the rotating plate 46 to realize steering detection, the component mounting hole includes a second mounting hole 452 arranged on the top plate 42 for mounting a proximity switch, and a third groove 473 less than one circle is arranged on the rotating plate 46 at a position corresponding to the second mounting hole 452.

[0041] like Figure 4 As shown, a half-circle third groove 473 is provided to realize the detection of the rotating plate 46 rotating 180 degrees, so as to facilitate the detection of the loading and unloading status.

[0042] In order to improve the stability of the goods, limit plates 461 are provided on both sides of the rotating plate 46. In order to facilitate processing, the limit plates 461 and the rotating plate 46 are fixed with bolts.

[0043] In order to facilitate the installation of related components, such as Figure 5 As shown, the bottom plate 41 is in a "cross" shape.

[0044] As described above, the reinforcing plate 44 is connected and fixed according to the strength requirement, and is connected to the bottom plate 41 and the two side plates 43 at the same time to further enhance the strength. A plurality of reinforcing plates 44 may also be provided, such as Figure 3 The following is an example of setting 2.

[0045] In order to facilitate automatic tracking and automatic charging in the loading scene, Figure 5 As shown, the component mounting holes include at least one third mounting hole 453 for mounting a sensor and a fourth mounting hole 454 for mounting a charging interface, which are arranged on the bottom plate 41 .

[0046] The second aspect of the utility model discloses an AGV vehicle, such as Figure 6 As shown, it includes a frame, and the frame is a frame structure described in the first aspect and any possible design thereof.

The bottom plate 41, top plate 42, side plate 43 and reinforcement plate are made by milling or die casting. Screw holes are processed in the relevant connection parts, and bolts are used to achieve detachable connection. The component mounting holes can also be directly processed by milling or die casting, which is convenient and quick to process.

[0048] like Figure 6 As shown, it is an overall structural diagram of an AGV vehicle, the driving motor 51 is fixed on the inner side of the top plate, the output shaft is fixed to the rotating plate 46, and the needle bearing 52 and the sealing ring 53 are respectively installed in the first groove 471 and the second groove 472 on the rotating plate 46 and the top plate.

[0049] The bottom plate fixes the reinforcement plate, side plates and corresponding components to support the weight of the vehicle. The side plates fix the lifting wheel system and corresponding components to bear the support force of the wheel system. The reinforcement block connects the bottom plate and the side plates to strengthen the lateral strength and prevent lateral bending. The top plate fixes the drive motor and the rotating plate and corresponding components to support the materials on the rotating plate. The rotating plate supports and fixes the materials.

[0050] A complete frame structure is formed by splicing several boards. It has a simple structure, is easy to process, and has good overall strength.
