The first mounting base 110 includes a first fixing plate 111, first uprights 112, a first crossbeam 113, and a first longitudinal beam 114. Specifically, the first fixing plate 111 has a square structure with a positioning hole 1111 at each of its four corners and a clearance hole 1112 in the center. There are four first uprights 112, each fixedly connected to one of the four corners of the first fixing plate 111 at its upper part. There are two first crossbeams 113, each fixedly connected to the bottom of opposite sides of the first fixing plate 111 at its top.

Specifically, the second fixed plate 121 has a square structure, and its plane is lower than the plane of the first fixed plate 111 by a first preset height. There are two second crossbeams 122, with their bottom ends fixedly connected to the tops of opposite sides of the second fixed plate 121, and one end fixedly connected to the middle of the two first columns 112 located at one end of the first fixed plate 111.

[0047] In this embodiment, the first mounting base 110 can serve as the mounting base for the drive mechanism of the submerged AGV, and the positioning hole 1111 on the first fixing plate 111 can be used as a motor mounting hole. The clearance hole 1112 allows the motor housing to pass through. The second mounting base 120 can serve as the mounting base for the electrical cabinet of the submerged AGV. The second fixing plate 121 serves as the support plate for the electrical cabinet, and its plane is lower than the plane of the first fixing plate 111 by a first preset height, specifically, the first preset height is 5-10cm, allowing the electrical cabinet to be installed in a recessed manner. The overall layout is relatively compact and reasonable, and the overall height of the submerged AGV in the vertical direction is relatively low. The first mounting base 110 is composed of the first fixing plate 111, the first column 112, the first crossbeam 113, and the first longitudinal beam 114, and the second mounting base 120 is composed of the second fixing plate 121 and the second crossbeam 122. Among them, the first column 112, the first crossbeam 113, the first longitudinal beam 114 and the second crossbeam 122 are all standard parts. Compared with the traditional form of the AGV frame which is composed of irregular sheet metal parts, the assembly difficulty of the AGV frame is greatly reduced, which effectively reduces the manufacturing difficulty of the AGV frame, thereby effectively improving the manufacturing efficiency and reducing labor, raw material and process costs.

[0048] In a specific embodiment of the present invention, the first column 112, the first horizontal beam 113, the first longitudinal beam 114, the second column 134, the second horizontal beam 122, the second longitudinal beam 133, the third horizontal beam 132, the fourth horizontal beam 135, the fifth horizontal beam 142, the sixth horizontal beam 151, the first connecting beam 152, the second connecting beam 153, the third connecting beam 154, and the fourth connecting beam 155 are all long, hollow structures, that is, the first column 112, the first horizontal beam 113, the first longitudinal beam 114, the second column 134, the second horizontal beam 122, the second longitudinal beam 133, the third horizontal beam 132, the fourth horizontal beam 135, the fifth horizontal beam 142, the sixth horizontal beam 151, the first connecting beam 152, the second connecting beam 153, the third connecting beam 154, and the fourth connecting beam 155 are all long, hollow structures. 4. The second upright 134, the second crossbeam 122, the second longitudinal beam 133, the third crossbeam 132, the fourth crossbeam 135, the fifth crossbeam 142, the sixth crossbeam 151, the first connecting beam 152, the second connecting beam 153, the third connecting beam 154, and the fourth connecting beam 155 are all standard parts that can be directly cut from square hollow tubes. This not only makes the components that make up the frame easier to obtain, but also makes the frame assembly easier, greatly improving manufacturing efficiency and reducing manufacturing costs.

[0049] In a specific embodiment of the present invention, the chassis of the concealed AGV further includes a third mounting base 130, which serves as a mounting base for the battery and RFID reader of the concealed AGV. The third mounting base 130 is integrally located at the other end of the first fixing plate 111 and includes a third fixing plate 131, a third crossbeam 132, a second longitudinal beam 133, a second column 134, a fourth crossbeam 135, and a partition plate 136. The third fixing plate 131 has a square structure, and its plane is lower than the plane of the first fixing plate 111 by a second preset height, specifically, the second preset height is 10-15 cm. The third fixing plate 131 serves as a support plate for the battery and RFID reader, allowing for a recessed installation of the battery and RFID reader, thus reducing the overall vertical height of the concealed AGV. A light-transmitting hole 1311 is provided in the middle of the third fixing plate 131, directly facing the RFID reader to facilitate the RFID reader reading the RFID electronic tag. There are two third crossbeams 132, each fixedly connected at its bottom to the top of opposite sides of the third fixing plate 131, and at one end fixedly connected to both ends of the same first longitudinal beam 114. There is one second longitudinal beam 133, with both ends fixedly connected to the ends of the two third crossbeams 132 furthest from the first longitudinal beam 114. There are two second columns 134, each fixedly connected at its bottom to both ends of the second longitudinal beam 133. There are two fourth crossbeams 135, one of which is fixedly connected at one end to the upper part of one first column 112 and at the other end to the upper part of one second column 134; the other is fixedly connected at one end to the upper part of another first column 112 and at the other end to the upper part of another second column 134. The two fourth crossbeams 135 provide protection for the battery and RFID reader on the third fixing plate 131. There are two partitions 136, both square in structure, with their planes perpendicular to the plane of the third fixed plate 131. One partition has its two ends fixedly connected to two first columns 112 located at the other end of the first fixed plate 111, and the other has its two ends fixedly connected to two second columns 134. The two partitions 136 isolate the electrical components on the chassis from each other, improving the safety and stability of the AGV during operation. Overall, this design facilitates chassis assembly and improves manufacturing efficiency.

[0050] In one specific embodiment of the present invention, the submerged AGV frame further includes a fourth mounting base 140 and a support base 150. The fourth mounting base 140 is integrally located at the end of the third mounting base 130 away from the first fixing plate 111, and includes a fourth fixing plate 141 and a fifth crossbeam 142. The fourth fixing plate 141 has a square structure, and its plane is lower than the plane of the first fixing plate 111 by a third preset height, specifically, the third preset height is 5-10 cm. A through hole 1411 is provided in the middle of the fourth fixing plate 141. There are two fifth crossbeams 142, whose bottoms are fixedly connected to the tops of opposite sides of the fourth fixing plate 141, and one end is fixedly connected to the middle of two second columns 134. The support base 150 is integrally located directly above the first mounting base 110 and the third mounting base 130. One end of the support base 150 extends beyond the first mounting base 110 by a first predetermined length, specifically 5-10 cm, to support and fix the traction mechanism of the submerged AGV. The other end of the support base 150 extends beyond the third mounting base 130 by a second predetermined length, specifically 5-10 cm, to protect the electrical components on the fourth fixing plate 141. The support base 150 includes a sixth crossbeam 151, a first connecting beam 152, a second connecting beam 153, a third connecting beam 154, and a fourth connecting beam 155. There are two sixth crossbeams 151. The bottom of one sixth crossbeam 151 is fixedly connected to the top of one first crossbeam 113 and the top of one fourth crossbeam 135. The bottom of the other sixth crossbeam 151 is fixedly connected to the top of another first crossbeam 113 and the top of another fourth crossbeam 135. The first connecting beam 152 is a single beam located directly above the second fixing plate 121, with both ends fixedly connected to one end of each of the two sixth crossbeams 151. The second connecting beam 153 is a single beam located directly above one end of the first fixing plate 111, with both ends fixedly connected to the middle of each of the two sixth crossbeams 151. The third connecting beam 154 is a single beam located directly above the other end of the first fixing plate 111, with both ends fixedly connected to the middle of each of the two sixth crossbeams 151. The fourth connecting beam 155 is a single beam located directly above the end of the third fixing plate 131 furthest from the first fixing plate 111, with both ends fixedly connected to the other ends of each of the two sixth crossbeams 151. Overall, the first mounting base 110, second mounting base 120, third mounting base 130, fourth mounting base 140, and support base 150 are not easily deformed, resulting in lower manufacturing costs and higher manufacturing efficiency.

[0051] In one specific embodiment of the present invention, each of the sixth crossbeams 151 has a side guide wheel receiving groove 1511 at both ends, and each side guide wheel receiving groove 1511 can accommodate one side guide wheel. In this way, the overall space occupied by the AGV is smaller, which is conducive to the miniaturization of the AGV and its more flexible movement.

[0052] In one specific embodiment of the present invention, the first mounting base 110, the second mounting base 120, the third mounting base 130, the fourth mounting base 140, and the support base 150 are all made of steel. This makes the frame less prone to deformation and extends its service life.

[0053] In a specific embodiment of the present invention, the first column 112 is connected to the first fixing plate 111, the first crossbeam 113 is connected to the first fixing plate 111, the first crossbeam 113 is connected to the first column 112, the first longitudinal beam 114 is connected to the first column 112, the second crossbeam 122 is connected to the first column 112, the second crossbeam 122 is connected to the second fixing plate 121, the third crossbeam 132 is connected to the third fixing plate 131, the third crossbeam 132 is connected to the first longitudinal beam 114, the second longitudinal beam 133 is connected to the third crossbeam 132, the second column 134 is connected to the second longitudinal beam 133, and the fourth crossbeam 135 is connected to the first column 111. 2. The fourth crossbeam 135 and the second column 134, the partition 136 and the first column 112, the partition 136 and the second column 134, the fifth crossbeam 142 and the fourth fixing plate 141, the fifth crossbeam 142 and the second column 134, the sixth crossbeam 151 and the first crossbeam 113, the sixth crossbeam 151 and the fourth crossbeam 135, the first connecting beam 152 and the sixth crossbeam 151, the second connecting beam 153 and the sixth crossbeam 151, the third connecting beam 154 and the sixth crossbeam 151, and the fourth connecting beam 155 and the sixth crossbeam 151 are all connected by welding. This further improves the overall stability of the frame structure, making the frame more impact-resistant, less prone to deformation, and effectively extending the service life of the submersible AGV. Overall, compared to the traditional method of welding irregularly shaped sheet metal parts, the welding difficulty of the AGV chassis is reduced, which effectively reduces the manufacturing difficulty of the AGV chassis, thereby greatly improving manufacturing efficiency and reducing labor, raw material and process costs.
