Description

Technical Field

[0001] This utility model relates to the field of automated guided vehicle technology, specifically to an AGV intelligent transport vehicle with an anti-collision structure. Background Technology

[0002] Automated Guided Vehicles (AGVs), also known as automated guided vehicles or automated guided transport vehicles, are industrial vehicles that load goods automatically or manually, travel automatically along a set route or tow a cargo trolley to a designated location, and then load the goods automatically or manually.

[0003] In some application scenarios, such as working in narrow passageways or transporting heavy objects in factory environments, AGV intelligent transport vehicles need to be equipped with anti-collision buffer structures to reduce damage to the AGV intelligent transport vehicles caused by collisions.

[0004] In existing technologies, some AGV intelligent transport vehicles are equipped with anti-collision structures. However, most existing AGV intelligent transport vehicles suffer from problems such as complex installation of the anti-collision structure or poor anti-collision sensitivity. For example, a utility model patent with authorization announcement number CN222589848U and patent name "Anti-collision Structure for Industrial Robots" uses a sliding embedding installation method to install and fix the anti-collision plate on the front and rear sides. Since the anti-collision plate is a metal structure and is also equipped with guide rods and sensors, the sliding embedding installation structure must have considerable stability, which inevitably leads to a relatively complex sliding embedding structure. In addition, the sensors in this solution are installed on the inside of the anti-collision plate through sensor fixing components. Within the impact range where the anti-collision plate collides but does not deform, it is difficult to detect the impact and brake the AGV intelligent transport vehicle in time. Utility Model Content

[0005] To address the problems of complex installation structure and poor sensitivity of existing AGV intelligent transport vehicles, this utility model provides an AGV intelligent transport vehicle with an anti-collision structure.

[0006] To solve the above-mentioned technical problems, this utility model provides an AGV intelligent transport vehicle with an anti-collision structure, including an AGV intelligent transport vehicle body and anti-collision devices respectively disposed on the front and rear sides of the AGV intelligent transport vehicle body. The anti-collision devices include an anti-collision beam, a mounting bracket, a proximity sensor, a detection plate, a connecting rod, and an elastic element. The mounting bracket is fixedly installed on the front or rear side of the AGV intelligent transport vehicle body. The end of the connecting rod is slidably installed on the mounting bracket, and the head end of the connecting rod is fixedly connected to the anti-collision beam. The elastic element is fitted onto the outer circumference of the connecting rod, and the front and rear ends of the elastic element respectively abut against the anti-collision beam and the mounting bracket. The detection plate is fixedly installed on the end of the connecting rod, and the proximity sensor is fixedly installed on the mounting bracket. The proximity sensor is disposed on the side of the detection plate adjacent to the anti-collision beam.

[0007] In an embodiment of this utility model, the mounting bracket is provided with a sliding sleeve arranged along the axial direction of the connecting rod, and the connecting rod is slidably installed in the sliding sleeve.

[0008] In an embodiment of this utility model, a pin is also included. An installation seat is installed on the inner side wall of the anti-collision beam. The installation seat has an installation groove and a pin hole that runs vertically through the rod. The first end of the connecting rod has a connecting hole that runs vertically through the rod. The first end of the connecting rod is installed in the installation groove by a pin that passes vertically through the pin hole and the connecting hole.

[0009] In an embodiment of this utility model, a gasket is also included. The gasket is installed at the beginning of the connecting rod. The diameter of the gasket is larger than the upper and lower openings of the mounting groove. One end of the elastic element is installed against the side of the gasket.

[0010] In an embodiment of this utility model, the end of the connecting rod has a threaded portion, and the detection plate is locked onto the threaded portion by a locking nut.

[0011] In an embodiment of this utility model, the elastic element is a compression helical spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By adopting the aforementioned AGV intelligent transport vehicle with an anti-collision structure, the anti-collision beam and the mounting bracket are connected by a connecting rod. The first end of the connecting rod is mounted on the anti-collision beam by a pin, and the second end is locked onto the mounting bracket by a lock nut. This connection method is simple in structure and facilitates the installation and disassembly of the anti-collision beam and the mounting bracket on the connecting rod, solving the problem of complex installation structure in existing AGV intelligent transport vehicles. Furthermore, the second end of the connecting rod forms a sliding connection with the mounting bracket, and a detection plate is fixedly installed at the second end of the connecting rod. Thus, when the front or rear of the AGV intelligent transport vehicle is impacted, the anti-collision beam stops moving due to the collision with the impacting object. Meanwhile, the AGV intelligent transport vehicle continues to move forward due to inertia. At this time, the mounting bracket moves along the connecting rod towards the anti-collision beam, and simultaneously moves the proximity switch away from the detection plate. When the proximity switch no longer detects the detection plate, it sends a control signal to the AGV intelligent transport vehicle, causing the AGV intelligent transport vehicle to stop moving and avoid further increasing the impact force. Because the proximity switch can move synchronously with the mounting bracket in the event of an impact, it can detect the impact in the first instance and control the AGV intelligent transport vehicle to stop moving in time. Therefore, the AGV intelligent transport vehicle has extremely high sensitivity, solving the problem of poor sensitivity in existing AGV intelligent transport vehicles. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] Please refer to the appendix. Figure 1 and appendix Figure 2 As shown, this embodiment provides an AGV intelligent transport vehicle 10 with an anti-collision structure, including an AGV intelligent transport vehicle body 100 and anti-collision devices 200 respectively disposed on the front and rear sides of the AGV intelligent transport vehicle body 100.

[0028] Combined with reference to the appendix Figure 1 To be continued Figure 5 As shown, the anti-collision device 200 includes an anti-collision beam 201, a mounting bracket 202, a proximity sensor 209, a detection plate 208, a connecting rod 206, and an elastic element 207. The mounting bracket 202 is fixedly connected to the front or rear side of the AGV intelligent transport vehicle body 100, for example, by welding or bolting, and the mounting bracket 202 is horizontally fixed to the front or rear side of the AGV intelligent transport vehicle body 100.

[0029] For ease of description, only the anti-collision device 200 installed on the front side of the AGV intelligent transport vehicle body 100 will be described below.

[0030] The anti-collision beam 201 is arranged on the front side of the AGV intelligent transport vehicle body 100. The anti-collision beam 201 is arranged parallel to the mounting bracket 202. The anti-collision beam 201 and the mounting bracket 202 are connected by connecting rods 206. There can be a pair of connecting rods 206, and the pair of connecting rods 206 are symmetrically arranged on the left and right sides of the AGV intelligent transport vehicle body 100.

[0031] See attached document Figure 4 and attached Figure 5 As shown, specifically, a mounting base 203 is fixedly installed on the inner side wall of the anti-collision beam 201. The mounting base 203 has a mounting groove 2031 and a pin hole 2032 that runs vertically through the base. The connecting rod 206 has two opposite ends, namely, a head end and a tail end. The head end of the connecting rod 206 extends into the mounting groove 2031, and the head end of the connecting rod 206 has a connecting hole 2061 that runs vertically through the base.

[0032] When the connecting rod 206 is installed in the mounting base 203, the first end of the connecting rod 206 extends into the mounting groove 2031. The pin 205 is inserted into the mounting groove 2031 from top to bottom. The pin 205 is inserted from the pin hole 2032 on the top surface of the mounting base 203 and passes through the connecting hole 2061 at the first end of the connecting rod 206 and the pin hole 2032 on the bottom surface of the mounting base 203 in sequence. Finally, a pin is inserted into the bottom end of the pin 205 so that the first end of the connecting rod 206 is installed in the mounting groove 2031.

[0033] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, a threaded portion 2062 is formed at the end of the connecting rod 206, and a smooth mounting hole 2021 is formed on the mounting bracket 202. The end of the connecting rod 206 passes through the mounting hole 2021 and is mounted on the mounting bracket 202 by a locking nut 210. The opening size of the mounting hole 2021 is larger than the diameter of the connecting rod 206, so that the mounting bracket 202 can slide smoothly along the connecting rod 206. The locking nut 210 is threaded onto the end of the connecting rod 206, which ensures that the connecting rod 206 will not fall off the mounting bracket 202.

[0034] The anti-collision beam 201 and the mounting bracket 202 are connected by a connecting rod 206. The first end of the connecting rod 206 is mounted on the anti-collision beam 201 by means of a pin 205, and the end of the connecting rod 206 is mounted on the mounting bracket 202 by means of a locking nut 210. This connection method has a simple structure and facilitates the installation and disassembly of the anti-collision beam 201 and the mounting bracket 202 on the connecting rod 206, thus solving the problem of complex installation structure of existing AGV intelligent transport vehicles.

[0035] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, the elastic element 207 is fitted onto the outer circumferential surface of the connecting rod 206, and its two ends respectively abut against the inner side wall of the anti-collision beam 201 and the outer side wall of the mounting bracket 202. The function of the elastic element 207 is that when the anti-collision beam 201 is impacted, the elastic element 207 compresses and deforms, thereby buffering the impact. In some embodiments, the elastic element 207 is a compression coil spring.

[0036] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, due to the presence of the mounting groove 2031 on the mounting base 203, in order to prevent the elastic element 207 from getting stuck in the mounting groove 2031, a gasket 204 is installed at the head end of the connecting rod 206. The diameter of the gasket 204 is larger than the upper and lower opening sizes of the mounting groove 2031. One end of the elastic element 207 is installed against the side of the gasket 204. The setting of the gasket 204 prevents the front end of the elastic element 207 from getting stuck in the mounting groove 2031.

[0037] Continue to refer to the appendix Figure 4 and attached Figure 5 As shown, the detection plate 208 is installed at the end of the connecting rod 206. Specifically, the detection plate 208 has a threaded hole, and the detection plate 208 is fixedly installed on the threaded portion 2062 at the end of the connecting rod 206 through this threaded hole. (See attached diagram.) Figure 5 As shown, to prevent the detection plate 208 from moving on the connecting rod 206, the diameter of the threaded portion 2062 at the end of the connecting rod 206 is smaller than the diameter of other parts of the connecting rod 206. That is, a step is formed at the threaded portion 2062 at the end of the connecting rod 206. After the detection plate 208 is installed in place on the threaded portion 2062, a locking nut 210 is screwed on the end of the threaded portion 2062 to press the detection plate 208 tightly against the step. Therefore, the detection plate 208 cannot move back and forth along the axial direction of the connecting rod 206, thus ensuring the accuracy of the installation position of the detection plate 208 on the connecting rod 206. In subsequent use, the detection plate 208 can move synchronously with the connecting rod 206, which is beneficial to improving the coordination sensitivity between the detection plate 208 and the proximity sensor 209.

[0038] See attached document Figure 4 and attached Figure 5As shown, the proximity sensor 209 is fixedly mounted on the mounting bracket 202. The proximity sensor 209 is positioned adjacent to the anti-collision beam 201 on the detection plate 208. The proximity sensor 209 works in conjunction with the detection plate 208 to sense the gap between itself and the detection plate 208. The proximity sensor 209 is communicatively connected to the AGV intelligent transport vehicle body 100, sending control signals to the control mainboard within the AGV intelligent transport vehicle body 100 to stop its movement. Specifically, when the proximity sensor 209 detects a gap distance between itself and the detection plate 208 greater than its minimum detection threshold, it sends a control signal to the control mainboard within the AGV intelligent transport vehicle body 100, causing the AGV intelligent transport vehicle body 100 to stop moving. It is understood that the proximity sensor 209 is purchased directly from the market, and the communication line connection between the proximity sensor 209 and the control mainboard within the AGV intelligent transport vehicle body 100 is existing technology, which will not be elaborated upon here.

[0039] In some embodiments, in order to improve the smooth sliding between the mounting bracket 202 and the connecting rod 206, a copper sliding sleeve is installed in the mounting hole 2021 of the mounting bracket 202, and the end of the connecting rod 206 passes through the sliding sleeve. In this way, the mounting bracket 202 slides between the sliding sleeve and the connecting rod 206, reducing the resistance when the mounting bracket 202 slides, which is beneficial to improving the reaction sensitivity of the AGV intelligent transport vehicle when a collision occurs.

[0040] See attached document Figure 6 and attached Figure 7 As shown, when the AGV intelligent transport vehicle collides, the anti-collision beam 201 stops moving due to the collision with the impacting object, while the AGV intelligent transport vehicle body 100 continues to move forward due to inertia. At this time, the mounting bracket 202 moves along the connecting rod 206 towards the anti-collision beam 201, compressing the elastic element 207. The elastic frame, deformed by the compression, applies a reaction force to buffer the impact force during the collision. Simultaneously, the connecting rod 206 drives the proximity switch away from the detection plate 208. When the proximity switch does not detect the detection plate 208, it sends a control signal to the AGV intelligent transport vehicle, causing the AGV intelligent transport vehicle to stop moving and avoid further increasing the impact force. Since the proximity switch can move synchronously with the mounting bracket 202 when impacted, it can detect the impact in the first time and control the AGV intelligent transport vehicle to stop moving in time. Therefore, the AGV intelligent transport vehicle has extremely high sensitivity, solving the problem of poor sensitivity in existing AGV intelligent transport vehicles.
