[0041] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0042] The following is combined with Figures 1 to 7The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a heavy-duty AGV is provided, comprising: a vehicle body 1; two sets of drive mechanisms 2, spaced apart along the length direction of the vehicle body 1 at the bottom of the vehicle body 1; each drive mechanism 2 includes a first steering component 21 and a drive component 22; the first steering component 21 is connected to the vehicle body 1; the drive component 22 is connected to the output end of the first steering component 21 and is used to drive the vehicle body 1 to move; the first steering component 21 is used to drive the drive component 22 to rotate; two sets of steering mechanisms 3, spaced apart along the width direction of the vehicle body 1 at the bottom of the vehicle body 1 and located between the two sets of drive mechanisms 2; each steering mechanism 3 includes a second steering component 31, a first support portion 32 and a first moving wheel 33; the second steering component 31 is connected to the vehicle body 1; the output end of the second steering component 31 is connected to the first support portion 32 and is used to drive the first support portion 32 to rotate; the first moving wheel 33 is disposed on the first support portion 32 and is used to support the movement of the vehicle body 1.

[0044] It should be noted that there are two first moving wheels 33, which are located on both sides of the first support part 32.

[0045] In this embodiment, by arranging two sets of drive mechanisms 2 along the length of the vehicle body 1 and two sets of steering mechanisms 3 along the width of the vehicle body 1, the drive unit in the drive mechanism 2 provides driving force to drive the vehicle body 1 to move. The two sets of drive mechanisms 2 and the two sets of steering mechanisms 3 are arranged in a cross shape to ensure the stability of the vehicle body 1 during movement, so that the overall width of the vehicle body 1 can be set to a narrower structure. The steering mechanism 3 only includes a second steering component 31, a first support component 32 and a first moving wheel 33. The structure is simple and does not include components such as drive motors and reducers. The size is small, further reducing the overall size. It only serves to support and rotate through the second steering component 31 in conjunction with the first steering component 21. This can reduce the turning radius of the vehicle body 1, improve the flexibility and passability of the vehicle body 1 during movement, meet the application requirements of heavy-duty AGVs that require the size to be as small as possible, and has a wide range of applications.

[0046] In one embodiment, such as Figure 3 As shown, the first steering component 21 includes: a first fixed part 211, which is connected to the vehicle body 1; a first rotating part 212, which is rotatably connected to the bottom of the first fixed part 211 and whose bottom is connected to the driving component 22; and a first driving member 213, which is disposed on the first rotating part 212 and whose output end is drivenly connected to the first fixed part 211 for driving the first rotating part 212 to rotate.

[0047] In this embodiment, when the vehicle body 1 turns, the first rotating part 212 is driven to rotate by the first driving member 213, and then the first rotating part 212 drives the driving component 22 to rotate, changing the direction of the driving component 22. At the same time, the first supporting part 32 is driven by the second steering component 31 to drive the first moving wheel 33 to turn synchronously, thereby realizing rotation, reducing the turning radius, and improving flexibility.

[0048] In one embodiment, such as Figure 3 As shown, the bottom of the first rotating part 212 is provided with a plurality of first guide posts 214 in the vertical direction, and the first guide posts 214 are slidably inserted into the driving component 22; a first elastic element 215 is provided between the first rotating part 212 and the driving component 22.

[0049] In this embodiment, the bottom of the first rotating part 212 slides in a vertical direction with the driving component 22 through the first guide post 214. At the same time, a first elastic element 215 is provided between the first rotating part 212 and the driving component 22, which plays a buffering role when passing through uneven road surfaces. When the driving component 22 passes through a concave surface, the elastic force of the first elastic element 215 presses down on the driving component 22, keeping the driving component 22 in contact with the concave surface, ensuring the overall passability and improving the stability during movement.

[0050] Specifically, such as Figure 3 As shown, the first elastic element 215 can be selected as a spring, and the number of springs can be selected according to actual needs. In this embodiment, two springs are preferably provided.

[0051] In one embodiment, such as Figure 3 As shown, the first driving component 213 is a first driving motor, which is mounted on the first rotating part 212; the first fixed part 211 has a first gear on its periphery around the axial direction of the first rotating part 212, and the output end of the first driving motor has a second gear, which meshes with the first gear and the second gear.

[0052] It should be noted that the axial direction of the second gear is parallel to the axial direction of the first gear.

[0053] In this embodiment, when it is necessary to adjust the steering of the drive component 22, the first drive motor drives the first gear to rotate, and then the first gear rotates around the second gear, thereby driving the first rotating part 212 to rotate.

[0054] In one embodiment, such as Figure 4 As shown, the drive component 22 includes: a second support portion 221, which is connected to the output end of the first steering component 21; a second moving wheel 222, which is rotatably connected to the second support portion 221 and is used to support the movement of the vehicle body 1; and a second drive member 223, which is disposed on the second support portion 221 and is used to drive the second moving wheel 222 to rotate.

[0055] It should be noted that the second support part 221 is provided with second moving wheels 222 on both sides.

[0056] In this embodiment, the second moving wheel 222 is driven to rotate by the second driving member 223, thereby driving the vehicle body 1 to move. During the movement, the second support part 221 is driven to rotate by the first steering member 21, thereby achieving steering.

[0057] Specifically, the first guide post 214 is slidably inserted into the second support part 221.

[0058] In one embodiment, such as Figure 4 As shown, the second driving component 223 is a second driving motor, a third gear is coaxially mounted on the second moving wheel 222, and a fourth gear is mounted on the output end of the second driving motor; the third gear is driven by the fourth gear through a chain.

[0059] It should be noted that the axial direction of the third gear is parallel to the axial direction of the fourth gear.

[0060] In this embodiment, the second driving component 223 adopts a second driving motor. The output end of the second driving motor drives the third gear to rotate, and then the third gear drives the fourth gear to rotate through the chain, which in turn drives the second moving wheel 222 to rotate.

[0061] Specifically, such as Figure 4 As shown, each second moving wheel 222 is provided with a corresponding second driving component 223 to improve driving force.

[0062] In one embodiment, such as Figure 5 and Figure 6 As shown, the second steering component 31 includes: a second fixed part 311, which is connected to the vehicle body 1; a second rotating part 312, which is rotatably connected to the bottom of the second fixed part 311 and whose bottom is connected to the first support part 32; and a third driving member 313, which is disposed on the second fixed part 311 and whose output end is drivenly connected to the second rotating part 312 for driving the second rotating part 312 to rotate.

[0063] In this embodiment, when the vehicle body 1 turns, the second rotating part 312 is driven to rotate synchronously by the third driving component 313, and then the second rotating part 312 drives the first support part 32 to rotate, changing the direction of the first moving wheel 33, and rotating synchronously with the driving component 22, reducing the turning radius and improving flexibility.

[0064] In one embodiment, such as Figure 6 As shown, the bottom of the second rotating part 312 is provided with a plurality of second guide posts 314 in the vertical direction, and the second guide posts 314 are slidably inserted into the first support part 32; a second elastic member 315 is provided between the second rotating part 312 and the first support part 32.

[0065] In this embodiment, the bottom of the second rotating part 312 slides vertically with the first support part 32 through the second guide post 314. At the same time, a second elastic element 315 is provided between the second rotating part 312 and the first support part 32, which plays a buffering role when passing through uneven road surfaces. When the first moving wheel 33 passes through the concave surface, the elastic force of the second elastic element 315 presses down on the first support part 32, driving the first moving wheel 33 to press down and keep the first moving wheel 33 in contact with the concave surface, ensuring the overall passability and improving the stability during movement.

[0066] Specifically, such as Figure 6 As shown, the second elastic element 315 can be a spring, and the number of springs can be selected according to actual needs. In this embodiment, two springs are preferably provided.

[0067] In one embodiment, such as Figure 6 As shown, the third driving component 313 is a third driving motor, which is mounted on the second fixed part 311; the second rotating part 312 has a fifth gear around its axial direction on its periphery, and the output end of the third driving motor has a sixth gear, with the fifth gear and the sixth gear meshing.

[0068] It should be noted that the axis of the fifth gear is parallel to the axis of the sixth gear.

[0069] In this embodiment, when it is necessary to adjust the direction of the first moving wheel 33, the sixth gear is driven to rotate by the third drive motor, and then the sixth gear rotates around the fifth gear, which in turn drives the second rotating part 312 and the first support part 32 to rotate, thereby realizing the direction of the first moving wheel 33.

[0070] The specific working principle of the heavy-duty AGV provided in this embodiment is as follows: Two sets of drive mechanisms 2 and two sets of steering mechanisms 3 are arranged in a cross shape to ensure the stability of the vehicle body 1 during movement. The steering mechanism 3 only includes a second steering component 31, a first support 32, and a first moving wheel 33. Its simple structure does not include drive motors, reducers, or other components, resulting in a smaller overall size. It only serves to support the vehicle and rotate via the second steering component 31 in conjunction with the first steering component 21, allowing the overall width of the vehicle body 1 to be set to a narrower structure. During operation, movement is achieved by driving the second moving wheel 222 to rotate via the second drive component 223. When turning, the first drive component 213 and the third drive component 313 work together to synchronously rotate the first moving wheel 33. The steering of the second moving wheel 222 can reduce the turning radius of the vehicle body 1, improve the flexibility and passability of the vehicle body 1 during movement, meet the application requirements of heavy-duty AGVs that require the smallest possible size, and has a wide range of applications. In addition, when traveling on uneven ground, if the ground in contact with a certain drive mechanism 2 or a certain steering mechanism 3 is concave, the second support part 221 or the first support part 32 at this position is pressed down under the action of the spring, so that the first moving wheel 33 or the second moving wheel 222 can maintain contact with the ground, ensuring that the vehicle body 1 can still travel normally. This solves the problem that the existing heavy-duty AGVs are large in overall size, and in actual use they cannot meet the application requirements of many heavy-duty AGVs that require the smallest possible size, thus limiting their applicability.

[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
