[0009] Preferably, the two support bars are fixedly connected to one end of the four sliding seats away from each other, and the one end of the four sliding seats away from each other are rotatably matched with four rotating frames. The installation of the sliding seats facilitates the sliding of the four electric push rods.

[0010] Preferably: the four sliding seats are fixedly connected to four electric push rods respectively, and the tops of the four rotating bars are fixedly installed with sliding rods that are slidably matched with the sliding seats. The installation of the sliding rods can guide the rotating bars during the sliding process, so that the sliding of the rotating bars is smoother.

[0011] Preferably, the four rotating frames are all L-shaped structures, and the upper surfaces of the four universal wheels are fixedly connected to the lower surfaces of the four rotating frames respectively.

[0014] 2. The utility model can drive the telescopic component to extend and retract and drive the two support bars to slide away from each other through the installation of a motor. After the two support bars slide away from each other, the two support bars can be supported on both sides of the goods. Because they can be supported on both sides of the goods, the goods are not easy to tip over.

DETAILED DESCRIPTION

[0024] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6As shown, an embodiment of the utility model provides an AGV transport vehicle chassis structure, including: an outer shell 1, a motor 2 is fixedly installed inside the outer shell 1, and four telescopic components 3 are rotatably arranged, and the ends of the four telescopic components 3 close to each other are fixedly installed with synchronous pulleys 4, and the circumferential sides of the four synchronous pulleys 4 are meshed with two synchronous belts 5, two of which are fixedly connected to the output ends of the motor 2, and two support bars 6 are fixedly installed on the four telescopic components 3, a rotating frame 7 is rotatably arranged on the telescopic components 3, and an electric push rod 8 is fixedly installed, and a fixed seat 9 is fixedly installed on the output end of the electric push rod 8, a rotating bar 10 is rotatably arranged between the fixed seat 9 and the rotating frame 7, and a universal wheel 11 is fixedly installed on the rotating frame 7.

[0027] In this embodiment, specifically: the telescopic component 3 includes a threaded rod 13 fixedly connected to the synchronous pulley 4, a sliding seat 14 threadedly matched with the threaded rod 13, and a guide block 15 fixedly connected to the sliding seat 14. The installation of the guide block 15 can guide the sliding seat 14 during the sliding process, so that the sliding seat 14 can slide more smoothly.

[0028] In this embodiment, specifically: four guide grooves are opened on the inner bottom wall of the shell 1, and four guide blocks 15 are respectively slidably arranged inside the four guide grooves. A cover plate 12 is fixedly installed on the upper surface of the shell 1, and a protrusion is arranged inside the shell 1. A rotating rod 16 fixedly connected to two of the synchronous pulleys 4 is rotatably arranged inside the protrusion. The installation of the cover plate 12 facilitates the sealing of the shell 1.

[0029] In this embodiment, specifically: the two support bars 6 are fixedly connected to the ends of the four sliding seats 14 that are away from each other, and the ends of the four sliding seats 14 that are away from each other are rotatably matched with the four rotating frames 7. The installation of the sliding seats 14 facilitates the sliding of the universal wheels 11.

[0030] In this embodiment, specifically: four sliding seats 14 are fixedly connected to four electric push rods 8 respectively, and the tops of the four rotating bars 10 are fixedly installed with sliding rods 17 that are slidably matched with the sliding seats 14. The installation of the rotating bars 10 facilitates the rotation of the rotating frame 7.

[0031] In this embodiment, specifically: the four rotating frames 7 are all L-shaped structures, the upper surfaces of the four universal wheels 11 are fixedly connected to the lower surfaces of the four rotating frames 7 respectively, and the installation of the universal wheels 11 facilitates the support of the goods.

[0032] When the utility model is working: when the rotating frame 7 and the universal wheel 11 need to rotate, the electric push rod 8 is turned on, and the turning of the electric push rod 8 drives the fixed seat 9 and the rotating bar 10 to slide, and the sliding of the fixed seat 9 drives the rotating frame 7, the rotating bar 10, and the universal wheel 11 to rotate. When the universal wheel 11 rotates, the universal wheel 11 contacts the ground. When the universal wheel 11 contacts the ground, the contact area between the transport vehicle and the ground increases.

[0033] When the two support bars 6 slide away from each other, the motor 2 is turned on. The turning on of the motor 2 drives the synchronous pulley 4 and the synchronous belt 5 to rotate. The rotation of the synchronous pulley 4 drives the telescopic component 3 to extend and retract. When the telescopic component 3 is extended, the two support bars 6 slide away from each other. After the two support bars 6 slide away from each other, the two support bars 6 support the two sides of the goods.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
