[0036] The present utility model provides an AGV mobile transportation device 100, as Figure 1 and Figure 2 shown, which includes: a driving mechanism 1 and a chassis 2. The driving mechanism 1 includes a driving wheel 11, a support member 14, a driving member 13, a transmission assembly 10, and heat dissipation fins 18. The first end of the support member 14 is mounted on the chassis 2, the driving member 13 is mounted on the second end of the support member 14, the transmission assembly 10 is rotatably arranged on the support member 14, and the transmission assembly 10 is connected to the output end of the driving member 13. The driving wheel 11 is in transmission cooperation with the first end of the transmission assembly 10, and the heat dissipation fins 18 are in transmission cooperation with the second end of the transmission assembly 10; the heat dissipation fins 18 are arranged close to the driving member 13. Specifically, the driving member 13 drives the driving wheel 11 to rotate through the transmission assembly 10, thereby driving the chassis 2 to move; the driving member 13 also drives the heat dissipation fins 18 to rotate through the transmission assembly 10. Moreover, the heat dissipation fins 18 are arranged close to the driving member 13. When the heat dissipation fins 18 rotate, the air flow near the driving member 13 will be accelerated, so that the heat generated by the driving member 13 is carried away by the flowing air, realizing heat exchange. In this way, the phenomenon that the driving member 13 overheats due to long-term operation can be avoided, and the service life of the driving member 13 can be effectively improved. Moreover, by using one driving member 13 to transmit power through the transmission assembly 10 and simultaneously driving the driving wheel 11 and the heat dissipation fins 18 to rotate and operate, the number of driving members 13 used is saved, and the production cost is reduced.

[0037] In some embodiments, as Figure 2As shown, the transmission assembly 10 includes a first rotating shaft 15, a second rotating shaft 19, a first gear 16 and a second gear 17. The first end of the first rotating shaft 15 is mounted on the output end of the driving member 13. The first gear 16 is sleeved outside the first rotating shaft 15. The heat dissipation fins 18 are mounted on the second end of the first rotating shaft 15. The heat dissipation fins 18 are disposed opposite to the driving member 13. The second rotating shaft 19 is rotatably disposed on the support member 14. The first end of the second rotating shaft 19 is fixed to the driving wheel 11. The second gear 17 is fixed to the second end of the second rotating shaft 19. The second gear 17 meshes with the first gear 16. Specifically, the driving member 13 is used to drive the first rotating shaft 15 to rotate, thereby driving the first gear 16 and the heat dissipation fins 18 to rotate. The rotation of the heat dissipation fins 18 accelerates the air flow in the vicinity and blows the air flow toward the driving member 13, reducing the temperature near the driving member 13. Since the first gear 16 meshes with the second gear 17, the first gear 16 will drive the second gear 17 to rotate. The second gear 17 drives the second rotating shaft 19 to rotate. The second rotating shaft 19 drives the driving wheel 11 to rotate. The driving wheel 11 moves on the ground to drive the AGV mobile transportation device 100 to travel. By the meshing of the first gear 16 and the second gear 17, the driving member 13 transmits power to the second rotating shaft 19, so that the same driving member 13 drives the driving wheel 11 and the heat dissipation fins 18 to rotate simultaneously. By setting the transmission ratio between the first gear 16 and the second gear 17, the rotation speed and torque of the driving wheel 11 can be changed.

[0038] In other embodiments, the heat dissipation fins 18 can also be disposed between the driving member 13 and the first gear 16, so that the heat dissipation fins 18 are disposed closer to the driving member 13.

[0039] In some embodiments, as Figure 3 shown, the support member 14 includes a support body 141, a bearing seat 142, and at least one support column 143. The support body 141 has a shaft hole 144. The bearing seat 142 is mounted in the shaft hole 144. One end of the second rotating shaft 19 passes through the shaft hole 144, so that the second rotating shaft 19 is rotatably matched with the bearing seat 142. The first end of the support column 143 is mounted on the support body 141. The driving member 13 is mounted on the second end of the support column 143. Specifically, the support body 141 is used to support the bearing seat 142, so that the second rotating shaft 19 is rotatably matched with the bearing seat 142. There is a bearing in the bearing seat 142. The bearing is used to reduce the frictional resistance when the second rotating shaft 19 is rotatably matched with the support body 141. At the same time, the support column 143 is used to fix the driving member 13, so that the driving member 13 is disposed on the support member 14, improving the stability of the driving member 13 on the support member 14.

[0040] In some embodiments, as Figure 3As shown, there are multiple support columns 143. The multiple support columns 143 are arranged at intervals, and there is a heat dissipation gap between two adjacent support columns 143. Specifically, the driving member 13 is supported by the multiple support columns 143, improving the stability of the driving member 13 on the support body 141. Moreover, there is a heat dissipation gap between two support columns 143, and the heat of the driving member 13 will be transferred through the support columns 143, thereby performing heat exchange with the air at the heat dissipation gap, further reducing the temperature of the driving member 13 during operation.

[0041] In some embodiments, as Figure 2 shown, the AGV mobile transportation device 100 further has a suspension assembly 12. The first end of the suspension assembly 12 is installed on the support member 14, and the second end of the suspension assembly 12 is installed under the chassis 2; the support member 14 is flexibly matched with the chassis 2 through the suspension assembly 12. Specifically, by providing the suspension assembly 12, the suspension assembly 12 is used to absorb the vibration potential energy between the chassis 2 and the support member 14, thereby improving the stability of the AGV mobile transportation device 100 during movement. The suspension assembly 12 includes an independent suspension, a double-wishbone independent suspension, a multi-link independent suspension, an air suspension, and there is no special limitation here.

[0042] Preferably, as Figure 2 shown, the suspension assembly 12 includes an air pipe 121, a compressor 122, a telescopic member 123, a sensor, and a solenoid valve. The compressor 122 and the telescopic member 123 are both installed on the support member 14. The first end of the air pipe 121 is communicated with the compressor 122, and the second end of the air pipe 121 is communicated with the telescopic member 123; the air pipe 121 has an exhaust port, and the solenoid valve is installed at the exhaust port (not shown in the figure), and the sensor is installed on the telescopic member 123 (not shown in the figure). The sensor is electrically connected to the compressor 122 and the solenoid valve respectively, and the sensor controls the compressor 122 and the solenoid valve through a control circuit respectively. Specifically, the telescopic member 123 is used for telescoping up and down and adjusting the height of the chassis 2. The sensor is used to sense the height from the ground. The sensor can send the height distance of the chassis 2 to the operation console. The compressor 122 transports gas to the telescopic member 123 through the air pipe 121, thereby adjusting the telescopic height of the telescopic member 123. When the height of the chassis 2 is relatively low, the operation console obtains the sensing threshold of the sensor, and thus controls the start or stop of the compressor 122 and the opening or closing of the solenoid valve through the control circuit, realizing the adjustment of the telescopic height of the telescopic member 123. There is a shock-absorbing spring in the telescopic member 123, and the shock-absorbing spring is further used to absorb the vibration potential energy between the chassis 2 and the support member 14. This suspension assembly 12 can adopt the prior art, such as Chinese Patent No. CN109551985B, which discloses an air spring assembly and an air suspension system, and will not be elaborated here one by one.

[0043] Preferably, as Figure 1As shown, the driving mechanism 1 further has a moving wheel set 3, and the moving wheel set 3 includes at least two moving wheels. The moving wheels are rotatably mounted under the chassis 2, and the driving wheel 11 and the moving wheels are arranged on the same horizontal plane. Specifically, the chassis 2 rolls on the ground through the moving wheels, and the driving wheel 11 pushes the chassis 2 to move when moving. The moving wheels also play a role in supporting the chassis 2, reducing the pressure exerted by the chassis 2 on the driving wheel 11 and reducing the frictional resistance between the driving wheel 11 and the ground.

[0044] In some embodiments, as Figure 1 and Figure 4 shown, the AGV mobile transportation device 100 further has a carrier 4 and a lifting assembly 5. The carrier 4 includes a first support plate 41 and a second support plate 42. Both ends of the lifting assembly 5 are respectively mounted on the first support plate 41 and the second support plate 42. The lifting assembly 5 is arranged between the first support plate 41 and the second support plate 42, and the second support plate 42 is mounted on the chassis 2. Specifically, the first support plate 41 is used to support the lifting assembly 5, improving the stability of the lifting assembly 5 on the chassis 2; the second support plate 42 is used to place the materials to be transported. The AGV mobile transportation device 100 transports the materials to a preset position, and the lifting assembly 5 is used to lift the second support plate 42, transporting the materials vertically and transporting the materials to a specified height position.

[0045] Preferably, as Figure 4 shown, the lifting assembly 5 includes a first cylinder 51, a first support rod 52, and a second support rod 53. The first ends of both the first support rod 52 and the second support rod 53 are rotatably connected to the second support plate 42, and the second ends of both the first support rod 52 and the second support rod 53 are rotatably connected to the first support plate 41; the first support rod 52 and the second support rod 53 are cross - arranged, and the middle sections of the first support rod 52 and the second support rod 53 are rotatably connected by a pin shaft; the first cylinder 51 is mounted on the chassis 2, and the first support rod 52 is fixed to the output end of the first cylinder 51. Specifically, the first cylinder 51 is used to push the first support rod 52 to move, so that the two ends of the first support rod 52 are respectively rotationally matched with the first support plate 41 and the second support plate 42, the two ends of the second support rod 53 are respectively rotationally matched with the first support plate 41 and the second support plate 42, and the middle section of the first support rod 52 is rotationally matched with the middle section of the second support rod 53. As the first support rod 52 and the second support rod 53 rotate, the first support plate 41 moves up or down, further realizing the transportation of the materials to a specified height position.

[0046] Preferably, there are two sets of lifting assemblies 5, and the two sets of lifting assemblies 5 are respectively arranged on both sides of the carrier 4. Specifically, two sets of lifting assemblies 5 are used to drive the first support plate 41 to move up or down simultaneously, improving the driving force of the first support plate 41, so that the carrier 4 can lift heavier materials.

[0047] It should be noted that in the AGV mobile transportation device 100, by arranging the heat dissipation fins 18 close to the driving member 13, and moreover, the driving member 13 drives the heat dissipation fins 18 and the driving wheel 11 to rotate simultaneously through the transmission assembly 10, so as to realize that the AGV mobile transportation device 100 uses one driving member 13 to realize the movement and heat dissipation of the device. In other AGV mobile transportation devices 100, the method of using the same driving member 13 to drive the driving wheel 11 to move and dissipate heat from the driving member 13 through the transmission assembly 10 is within the protection scope of this application.

[0048] When referring to the drawings for explanation, it is to explain the newly emerged features; in order to avoid the description being not concise enough due to repeated reference to the drawings, for the features that have been described clearly, the drawings are not cited one by one.
