DETAILED DESCRIPTION

[0019] Example

[0020] See also Figure 1-5 , the utility model provides a technical solution:

[0021] An unmanned automated guided vehicle, wherein an anti-collision mechanism 2 is fixedly connected to the surface of an AGV body 1, and the anti-collision mechanism 2 is installed on the outside of the AGV body 1. The anti-collision mechanism 2 can be used to provide anti-collision protection for the outside of the AGV body 1, thereby preventing the AGV body 1 from colliding with obstacles during operation, thereby preventing the body from being damaged.

[0022] The anti-collision mechanism 2 is provided in four groups, and the four groups of anti-collision mechanisms 2 are respectively installed at the four corners of the AGV body 1, so as to further protect the corners and sides of the AGV body 1. Two groups of fixing modules are provided on each group of anti-collision mechanisms 2, and the two groups of fixing modules are installed on two adjacent sides of the AGV body 1. A shock absorbing module is installed between the two groups of fixing modules, so as to further protect the corners and sides of the AGV body 1 from collision.

[0023] The fixing module includes a fixing base 201 installed on the side of the AGV body 1. The fixing base 201 is set in an "L" shape. A vertical slot 202 is set inside the fixing base 201. Two groups of limit rods 203 are fixedly connected to the inner wall of the slot 202. The surfaces of the two groups of limit rods 203 are sleeved with clamps 204. At the same time, the upper end surface of the fixing base 201 is provided with a threaded hole and a fixing bolt 205 is inserted into the threaded hole. The lower end of the fixing bolt 205 abuts against the surface of the clamp 204. After the fixing base 201 is placed on the side of the AGV body 1, the lower end surface of the fixing base 201 abuts against the lower end surface of the AGV body 1, and the fixing bolt 205 is further tightened in the threaded hole, and the clamp 204 is controlled to be pressed against the upper end surface of the AGV body 1, so that the fixing module can be clamped and fixed on the AGV body 1.

[0024] The shock absorbing module includes a sleeve 206 installed on the surface of the fixed base 201, a rod 207 is inserted inside the sleeve 206, a fixed shaft 208 is fixedly connected to the outer end surface of the rod 207, a hinge block 209 is hinged on the surface of the fixed shaft 208, and a bumper plate 210 is fixedly connected to the surface of the hinge block 209. At the same time, a spring 218 is fixedly connected to one end of the rod 207 inserted inside the sleeve 206, and the other end of the spring 218 is connected to the inner wall of the sleeve 206. When the AGV body 1 collides with an obstacle at one end, the obstacle is blocked by the bumper plate 210, further avoiding direct contact between the obstacle and the AGV body 1. When the anti-collision plate 210 is hit by an external force, the anti-collision plate 210 will push the insertion rod 207 to slide into the sleeve 206 and squeeze the spring 218, so that the elastic force of the spring 218 can further buffer the collision force on the anti-collision plate 210, further avoiding collision damage to the AGV body 1.

[0025] A mounting shaft 211 is inserted on one side of the anti-collision plate 210, and a connecting plate A212 and a connecting plate B213 are installed between the two groups of shock absorbing modules on both sides of the corners of the AGV body 1. The connecting plates A212 and B213 are respectively hinged on the mounting shafts 211 set on the surfaces of the two groups of anti-collision plates 210. The connecting plate A212 is set as a "T"-shaped structure, and the connecting plate B213 is set as a "U"-shaped structure. The connecting plate A212 is inserted into the connecting plate B213 in a matching manner. At the same time, the upper and lower surfaces of the connecting plate A212 are connected to the limiting strips 214. The inner wall of the connecting plate B213 is provided with a limiting slide groove 215. The limiting strip 214 is inserted into the limiting slide groove 215 in a matching manner, and the sliding connection between the connecting plate A212 and the connecting plate B213 is further controlled. The two adjacent sets of mounting shafts 211 can be connected together by connecting plates A212 and B213, further effectively protecting the corners of the AGV body 1. When a collision occurs at any position of the corners of the AGV body 1, the AGV body 1 can be effectively buffered. The two sets of anti-collision plates 210 are connected by connecting plates A212 and B213, so that the gap between the two sets of anti-collision plates 210 can also be blocked. When the connecting plates A212 and B213 are collided, the two sets of anti-collision plates 210 will be pulled toward the center, and during the rotation process, the plug rod 207 is pushed to insert into the sleeve 206 to squeeze the spring 218, so that the shock absorbing module can fully protect the corners of the AGV body 1.

[0026] At the same time, two sets of stabilizing mechanisms 3 are installed on the side of the AGV body 1, and the two sets of stabilizing mechanisms 3 are symmetrically distributed. When the AGV body 1 collides, the collision force is buffered by the anti-collision mechanism 2, and the anti-collision mechanism 2 drives the two sets of stabilizing mechanisms 3 to operate, so that the two sets of stabilizing mechanisms 3 can further clamp and stabilize the goods placed on the surface of the AGV body 1, so as to prevent the goods from falling and being damaged due to the shaking of the AGV body 1 during the collision.

[0027] The stabilizing mechanism 3 includes a fixed tube 301 installed between two groups of sleeves 206, the lower end of the fixed tube 301 is set as a "T" structure, and the upper end of the fixed tube 301 is set as an "L" structure. Two groups of piston blocks A302 are inserted inside the lower end of the fixed tube 301, and a piston block B303 is inserted inside the upper end of the fixed tube 301. Compressed air is filled between the piston blocks A302 and B303. At the same time, a pressure rod 304 is fixedly connected to the surface of the piston block B303, one end of the pressure rod 304 passes through the outside of the fixed tube 301 and is fixedly connected to a pressure plate 305, and the two groups of pressure plates 305 are relatively arranged on the upper surface of the AGV body 1. A push rod 306 is fixedly connected to the surface of the piston block A302, and a connecting rod 307 is hinged to the rear end of the push rod 306. A slot 308 is provided on the surface of the fixed tube 301. One end of the connecting rod 307 passes through the slot 308 and is hinged to a protrusion 216 provided on the surface of the anti-collision plate 210. A connecting shaft 217 is fixedly connected to the surface of the protrusion 216, and one end of the slot 308 is sleeved on the connecting shaft 217.

[0028] When the AGV body 1 collides and shakes, the anti-collision mechanism 2 is used for anti-collision buffering. At the same time, when the anti-collision mechanism 2 is hit, it will control the anti-collision plate 210 to move, further control the anti-collision plate 210 to push the connecting rod 307 to rotate, and control the connecting rod 307 to push the push rod 306 to slide, so that the push rod 306 pushes the piston block A302 to squeeze the compressed air in the fixed tube 301, further pushes the piston block B303 connected to the pressure rod 304 to slide outward, and controls the distance between the two sets of pressure plates 305 to decrease, further clamps the goods to prevent the goods from falling due to shaking. When the anti-collision plate 210 is in the initial state, it is pushed outward to the farthest end under the elastic force of the spring 218. The surface of one end of the insertion rod 207 inserted in the sleeve 206 is fixedly connected to the limiting block 220. The surface of the sleeve 206 is provided with a matching limiting groove 219. The limiting block 220 is matched and inserted in the limiting groove 219. The sliding of the insertion rod 207 is further limited by the limiting block 220, so that the insertion rod 207 cannot be pushed outward, and the connecting rod 307 is further controlled to be unable to pull the push rod 306 to slide outward, resulting in an increase in the distance between the two sets of pressure plates 305, thereby ensuring the stability of the clamping of the goods by the stabilizing mechanism 3.
