[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 The present invention provides an embodiment of a logistics AGV (Automated Guided Vehicle), comprising a transport vehicle 1 for carrying goods for transportation. The transport vehicle 1 has a clamping adjustment mechanism 2 on its inner wall, which adjusts the clamping of goods to accommodate different sizes. A fixing mechanism 3 is provided on the side wall of the transport vehicle 1. The clamping adjustment mechanism 2 includes a bidirectional screw 211, both ends of which are rotatably connected to the inner wall of the transport vehicle 1. The bidirectional screw 211 is driven to rotate by a motor 224 to achieve subsequent adjustment. A screw hole seat 212 is threadedly connected to the outer wall of the bidirectional screw 211. The screw hole seat 212 moves along its outer wall when the bidirectional screw 211 rotates. A hinged connecting rod 213 is hinged to the inner wall of the screw hole seat 212. The hinged connecting rod 213 pushes other components through the hinge action when the screw hole seat 212 moves. A hinged seat 214 is hinged to the other end of the hinged connecting rod 213. Driven by 3, the support plate 215 moves. The support plate 215 is fixedly connected to the side wall of the hinge seat 214. The outer wall of the support plate 215 is slidably connected to the inner wall of the transport vehicle 1. The support plate 215 slides on the inner wall of the transport vehicle 1 under the drive of the hinge seat 214. A clamping frame 216 is provided on the top of the support plate 215. The clamping frame 216 is used to clamp the goods. A lifting groove 217 is opened on the inner wall of the clamping frame 216. The lifting groove 217 provides a space for the lifting plate 219 and the adjusting screw 218. The adjusting screw 218 is rotatably connected to the top of the inner wall of the lifting groove 217. The adjusting screw 218 is rotated by the knob 221 to adjust the height of the lifting plate 219. The lifting plate 219 is threadedly connected to the outer wall of the adjusting screw 218. The lifting plate 219 rises or falls when the adjusting screw 218 rotates. A clamping plate 220 is fixedly connected to the top of the lifting plate 219. The clamping plate 220 moves with the lifting plate 219 to adapt to the height of the goods.

[0032] Reference Figures 1-3The clamping and adjusting mechanism 2 also includes a knob 221, the top of which is fixedly connected to the bottom of the adjusting screw 218. Manual rotation of the knob 221 drives the adjusting screw 218 to rotate. The clamping and adjusting mechanism 2 also includes a limiting rod 222, both ends of which are fixedly connected to the inner wall of the lifting groove 217. The limiting rod 222 limits the lifting plate 219, allowing it to slide only along its outer wall. The outer wall of the limiting rod 222 is slidably connected to the inner wall of the lifting plate 219. The clamping and adjusting mechanism 2 also... The clamping and adjusting mechanism 2 includes a limiting groove 223, which is formed on the inner wall of the carrier 1. The limiting groove 223 limits the screw hole seat 212, so that the screw hole seat 212 can only slide on its inner wall. The bottom outer wall of the screw hole seat 212 is slidably connected to the inner wall of the limiting groove 223. The clamping and adjusting mechanism 2 also includes a motor 224, whose outer wall is fixedly connected to the outer wall of the carrier 1. The output end of the motor 224 is fixedly connected to one end of the bidirectional screw 211, and the motor 224 provides power for the rotation of the bidirectional screw 211.

[0033] Reference Figure 3 , Figure 4 The fixing mechanism 3 includes a fixing block 311, the outer wall of which is fixedly connected to the side wall of the clamping frame 216. The fixing block 311 is used to connect the clamping frame 216 and the support plate 215. The fixing mechanism 3 also includes a positioning hole 312, which is opened on the outer wall of the fixing block 311. The positioning hole 312 provides an installation position for the positioning screw 313. The fixing mechanism 3 also includes a positioning screw 313, the inner wall of which is threadedly connected to the inner wall of the support plate 215. The positioning screw 313 fixes the fixing block 311 to the support plate 215 through the threaded connection. The clamping frame 216 is detachably connected to the top of the support plate 215 through the fixing block 311, the positioning hole 312 and the positioning screw 313, which facilitates the replacement or maintenance of the clamping frame 216.

[0034] Working principle: When the transport vehicle 1 needs to transport oversized goods, the motor 224 is started, causing the output end of the motor 224 to drive the fixedly connected bidirectional screw 211 to rotate, thereby driving the threaded hole seat 212 connected to the outer wall of the bidirectional screw 211 to move. This causes the bottom end of the threaded hole seat 212 to slide on the inner wall of the limiting groove 223, thus limiting the threaded hole seat 212. The two threaded hole seats 212 drive the hinged connecting rod 213 on the inner wall to move closer to each other. Under the hinge action of the hinge connecting rod 213, the hinge seat 214 and the support plate 215 are pushed to move. The support plate 215 then drives the clamping frame 216 to move, thereby adjusting the distance between the two clamping frames 216 according to the width of the goods, so as to place the goods on the top of the transport vehicle 1.

[0035] By manually rotating knob 221, the knob 221 drives the fixedly connected adjusting screw 218 to rotate. Under the limiting action of limit rod 222, the lifting plate 219, which is threadedly connected to the outer wall of the adjusting screw 218, rises. The lifting plate 219 then drives the clamping plate 220 to rise on the inner wall of the lifting groove 217, so that the height can be adjusted according to the height of the goods. Subsequently, the motor 224 can be rotated in the opposite direction, and the two clamping frames 216 and the clamping plate 220 move closer to each other, so that the goods can be clamped for subsequent transportation.

[0036] When the clamping frame 216 and clamping plate 220 are damaged or require maintenance, the positioning screw 313 on the fixing block 311 can be removed so that the positioning screw 313 is no longer threaded to the inner wall of the support plate 215. This will eliminate the limiting fixation between the fixing block 311 and the support plate 215, making it easier to remove and replace or maintain the clamping frame 216 and clamping plate 220 on the top of the support plate 215.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
