Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of intelligent transportation equipment, in particular to an anti-collision device and an intelligent transportation vehicle. Background Art
[0002] In machinery production, intelligent transport vehicles (such as AGVs or RGVs) are often used to transport equipment parts. Intelligent transport vehicles can automatically guide delivery, reducing labor costs and improving delivery efficiency.
[0003] When using intelligent transport vehicles, workers often occupy the transport route while carrying equipment, or multiple transport routes intersect, causing the intelligent transport vehicle to collide with other equipment or workers. In the prior art, a buffer device is often installed on the front side of the intelligent transport vehicle. When the intelligent transport vehicle collides with an obstacle, the buffer device can reduce the running speed of the intelligent transport vehicle, thereby reducing the impact force between the intelligent transport vehicle and the obstacle, and preventing the intelligent transport vehicle from being damaged by the collision. However, this method only reduces the impact force on the intelligent transport vehicle. The intelligent transport vehicle will still collide with obstacles, and long-term use will still damage the intelligent transport vehicle. In addition, after the intelligent transport vehicle collides with an obstacle, the parts transported by the intelligent transport vehicle will shake, and in serious cases, the parts will be damaged, increasing production costs.

[0036] Example 1
[0037] This embodiment provides an anti-collision device, which is configured to be installed on the front side of the intelligent transport vehicle. Figures 1 to 4 As shown, the intelligent transport vehicle can be prevented from colliding with obstacles, thereby avoiding damage to the intelligent transport vehicle and extending its service life. It can also prevent the transported parts from shaking due to collision and avoid damage to the parts.
[0038] like Figure 1 and Figure 2 As shown, the anti-collision device includes a base 1, a top plate 2, a rotation module 3, a measuring module 4 and a control module. Among them, the base 1 is arranged on the body of the intelligent transport vehicle. Along the front and rear directions of the vehicle body, the top plate 2 and the base 1 are spaced apart. The rotation module 3 is arranged between the base 1 and the top plate 2, and at least one rotation module 3 is provided. The rotation module 3 includes a first connecting member 31 and a second connecting member 32, one end of the first connecting member 31 is rotatably connected to the base 1, and the other end is rotatably connected to the second connecting member 32, and the end of the second connecting member 32 away from the first connecting member 31 rotates with the top plate 2. The first connecting member 31 is provided with a socket 311, and the second connecting member 32 is provided with a piece to be measured 321, and the piece to be measured 321 can be rotatably inserted into the socket 311. When the top plate 2 is compressed, it pushes the second connector 32 to rotate about the connection point between the first connector 31 and the second connector 32, and drives the first connector 31 to rotate about the connection point between the first connector 31 and the base 1, causing the second connector 32 to gradually approach the first connector 31. During this process, the second connector 32 drives the test piece 321 to rotate and approach the first connector 31 until the test piece 321 is inserted into the socket 311. The detection module 4 is disposed on the first connector 31 and is used to detect whether the test piece 321 is inserted into the socket 311. The control module is communicatively connected to the detection module 4 and the intelligent transport vehicle and is used to control the intelligent transport vehicle to dock or operate.
[0039] When an obstacle appears on the running route of the intelligent transport vehicle, the obstacle will squeeze the top plate 2. After being compressed, the top plate 2 will push the second connecting member 32 to rotate around the connection point of the first connecting member 31 and the second connecting member 32, so that the second connecting member 32 has a movement trend close to the first connecting member 31. At the same time, the second connecting member 32 will drive the first connecting member 31 to rotate around the connection point between the first connecting member 31 and the base 1, so that the first connecting member 31 and the second connecting member 32 are both rotated close to the base 1, thereby causing the anti-collision device to fold and compress. During this process, the second connecting member 32 will drive the piece to be tested 321 to rotate in the direction close to the first connecting member 31 until the piece to be tested 321 is inserted into the socket 311. At this time, the object measuring module 4 detects that the piece to be tested 321 is inserted into the socket 311, and sends a signal to the control module, so that the control module controls the intelligent transport vehicle to stop.
[0040] When an obstacle blocks the intelligent transport vehicle, the obstacle will first contact the top plate 2 of the anti-collision device and squeeze the top plate 2, causing the anti-collision device to fold and compress. As the anti-collision device continues to fold, the part to be tested 321 will be inserted into the socket 311, which is detected by the object measurement module 4, and the control module controls the intelligent transport vehicle to stop in time, which can prevent the intelligent transport vehicle from colliding with the obstacle, avoid damage to the intelligent transport vehicle, and extend its service life. It can also prevent the carried parts from shaking due to collision, avoid damage to the parts.
[0041] In this embodiment, two rotation modules 3 are provided, and the two rotation modules 3 are symmetrically arranged. In other embodiments, one or more rotation modules 3 may be provided as needed, and this is not limited here. When multiple rotation modules 3 are provided, the multiple rotation modules 3 are spaced apart along the width of the vehicle body. The provision of multiple rotation modules 3 can improve the support stability of the anti-collision device.
[0042] Illustratively, the object detection module 4 includes a U-shaped photoelectric sensor. The U-shaped photoelectric sensor is disposed on the first connector 31, with the U-shaped opening aligned with the insertion hole 311. When the object to be detected 321 is inserted into the insertion hole 311, the U-shaped photoelectric sensor's signal receiving and signal transmitting ends are blocked, preventing the U-shaped photoelectric sensor's signal receiving end from receiving signals, thereby detecting that the object to be detected 321 is inserted into the insertion hole 311. In other embodiments, a through-beam photoelectric sensor or the like may be selected as the object detection module 4, depending on actual needs, and this is not limited here.
[0043] Alternatively, as Figure 1 and Figure 2As shown, the rotation module 3 also includes a first shaft reset assembly 33 and a second shaft reset assembly 34. The first shaft reset assembly 33 is arranged between the first connecting member 31 and the base 1, and the second shaft reset assembly 34 is arranged between the first connecting member 31 and the second connecting member 32. When the test piece 321 is inserted into the socket 311, the intelligent transport vehicle will stop, and then the moving direction of the intelligent transport vehicle will be changed to separate the obstacle from the top plate 2 of the anti-collision device. The first shaft reset assembly 33 will drive the first connecting member 31 to rotate around the connection point between the first connecting member 31 and the base 1 and move away from the base 1. The second shaft reset assembly 34 will drive the second connecting member 32 to rotate around the connection point between the first connecting member 31 and the second connecting member 32 and move away from the first connecting member 31, thereby causing the top plate 2 to move along the front-to-back direction of the vehicle body and continuously move away from the base 1 until the top plate 2 moves to an un-pressed state. At this time, the test piece 321 rotates out of the socket 311 so that the anti-collision device can squeeze the obstacle again.
[0044] Alternatively, as Figure 1 、 Figure 2 and Figure 3 As shown, both the first rotation shaft reset assembly 33 and the second rotation shaft reset assembly 34 include a first rotation shaft 331, a first reset member 332, and a first stop member 333. The first reset member 332 is sleeved onto the first rotation shaft 331. The first rotation shaft 331 of the first rotation shaft reset assembly 33 passes through the base 1 and the first connecting member 31 and is locked with the first stop member 333, allowing the first connecting member 31 to rotate about the first rotation shaft 331. The first rotation shaft 331 of the second rotation shaft reset assembly 34 passes through the first connecting member 31 and the second connecting member 32 and is locked with the first stop member 333, allowing the first connecting member 31 and the second connecting member 32 to rotate about the first rotation shaft 331.
[0045] When the top plate 2 of the anti-collision device separates from the obstacle, the first reset member 332 of the first rotation axis reset assembly 33 pushes the first connecting member 31 to rotate around the first rotation axis 331 of the first rotation axis reset assembly 33 and moves the first connecting member 31 away from the base 1. The first reset member 332 of the second rotation axis reset assembly 34 pushes the second connecting member 32 to rotate around the first rotation axis 331 of the second rotation axis reset assembly 34 and moves the second connecting member 32 away from the first connecting member 31. That is, the top plate 2 moves along the front-to-back direction of the vehicle body and gradually moves away from the base 1, thereby moving the top plate 2 to the initial position. At this time, the test piece 321 rotates out of the socket 311. In addition, by providing the first limiting member 333, the first rotation axis 331 can be axially limited to prevent the first rotation axis 331 of the first rotation axis reset assembly 33 from being separated from the first connecting member 31 and the base 1, and to prevent the first rotation axis 331 of the second rotation axis reset assembly 34 from being separated from the second connecting member 32 and the first connecting member 31.
[0046] Illustratively, the first restoring member 332 includes a spring, and the first limiting member 333 includes a snap ring.
[0047] Alternatively, as Figure 1 and Figure 2 As shown, the base 1 includes a base plate 11 and a mounting base 12. The base plate 11 is connected to the front side of the vehicle body, and the mounting base 12 is located on the side of the base plate 11 facing away from the vehicle body. The first connector 31 is rotatably connected to the mounting base 12. The base plate 11 allows the anti-collision device to be installed on the vehicle body according to the shape of the intelligent transport vehicle, providing a mounting base for the anti-collision device. The mounting base 12 provides a rotational connection base for the first connector 31, facilitating its rotation around the mounting base 12.
[0048] Alternatively, as Figure 1 and Figure 2 As shown, the rotation module 3 also includes a second stopper 35. The top plate 2 defines a through-hole 1 21, and the mounting base 12 defines a through-hole 2 121. The second stopper 35 has two ends connected to the through-hole 1 21 and the through-hole 2 121, respectively. The second stopper 35 has a tensioned state and a relaxed state. When an obstacle presses against the top plate 2, the top plate 2 moves toward the base 1, causing the second stopper 35 to switch from the tensioned state to the relaxed state. As the top plate 2 moves closer to the base 1, the anti-collision device is partially folded. When the obstacle is separated from the top plate 2, the first shaft reset assembly 33 and the second shaft reset assembly 34 drive the top plate 2 to move in the direction away from the base 1 until the second limit member 35 is tightened, that is, the second limit member 35 is switched from a relaxed state to a tightened state. At this time, the second limit member 35 will tighten the top plate 2, so that the top plate 2 cannot move again, thereby limiting the top plate 2 in the front and rear directions of the vehicle body, preventing the top plate 2 from moving forward too much and causing the anti-collision device to fail, ensuring that the anti-collision device returns to its initial state, so that the anti-collision device can interact with the obstacle again.
[0049] In an exemplary embodiment, the second limiting member 35 includes a chain. In other embodiments, a rope or the like can be selected as the second limiting member 35 according to actual needs, which is not limited here.
[0050] Alternatively, as Figure 1 、 Figure 2 and Figure 4 As shown, the rotation module 3 includes a second rotation axis 36 and a third stopper 37. The second rotation axis 36 vertically passes through the top plate 2 and is locked with the third stopper 37. The second connecting member 32 is rotatably mounted on the second rotation axis 36. The provision of the second rotation axis 36 allows the second connecting member 32 to rotate about the second rotation axis 36, thereby strengthening the connection between the second connecting member 32 and the top plate 2, allowing the second connecting member 32 to rotate smoothly and ensuring the overall stability of the anti-collision device.
[0051] Optionally, the anti-collision device further includes a second reset member. One end of the second reset member is connected to the top plate 2, and the other end is connected to the base 1. When an obstacle presses against the top plate 2, the top plate 2 gradually approaches the base 1, partially collapsing the anti-collision device. During this process, the second reset member is continuously compressed. When the top plate 2 separates from the obstacle, the second reset member moves the top plate 2 away from the base 1 until it returns to its initial state, facilitating the anti-collision device's interaction with the obstacle.
[0052] Exemplarily, the second return member includes a spring.
[0053] Optionally, the anti-collision device further includes a protective member, which is disposed on the side of the top plate 2 facing away from the base 1. When an obstacle presses against the anti-collision device, the obstacle first contacts the protective member, thereby preventing the obstacle from directly rubbing against the top plate 2 and preventing damage to the top plate 2 due to the obstacle being too sharp, thereby ensuring the normal use of the anti-collision device.
[0054] Exemplarily, the protective member includes a sponge layer. In other embodiments, silicone or rubber can be selected as the protective member according to actual needs, which is not limited here.
[0055] Example 2
[0056] This embodiment provides an intelligent transport vehicle, comprising a vehicle body and the anti-collision device described above. The vehicle body comprises a frame and at least two running wheels disposed on the frame, the running wheels being disposed on opposite sides of the frame, and a base plate 11 of the anti-collision device being disposed on the front side of the frame. Parts are placed on the intelligent transport vehicle, and the parts can be transported to a target location by driving the running wheels to roll. The intelligent transport vehicle is also provided with an anti-collision device, which can prevent the intelligent transport vehicle from colliding with obstacles, thereby avoiding damage to the intelligent transport vehicle and extending its service life. It can also prevent the transported parts from shaking due to collisions, thereby avoiding damage to the parts.
[0057] Exemplarily, 2, 4, or 6 running wheels are provided. In other embodiments, other numbers of running wheels can also be provided according to actual needs, which is not limited here.
[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
