[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Second, the "one embodiment" or "embodiment" mentioned herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0030] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions of length, width, and depth should be included.

[0031] Embodiment 1, referring to Figure 1-Figure 4 , a material cart for workshop transportation is provided, including a fixing frame 100 with a first loading part 101 inside and a second loading part 102 located below the first loading part 101; a locking component 200 including a moving part 201 and a rotating part 202, both of which are arranged on the second loading part 102; wherein, the second loading part 102 can be pulled out from the fixing frame 100.

[0032] The fixing frame 100 is integrally in a "U" shape, with the first loading part 101 fixedly arranged at its upper end. Inside the fixing frame 100 and below the first loading part 101, there is a second loading part 102 which can be pulled out from one side of the fixing frame 100. Installation plates are fixedly arranged on both sides of the fixing frame 100, enabling the fixing frame 100 to be fixed on an AGV trolley, so that the AGV trolley can transport materials through the device. A locking component 200 is arranged at the top of the second loading part 102, and it is fixed to the first loading part 101 through the locking component 200, so that the second loading part 102 can be stored in the fixing frame 100 during daily transportation for convenient material transportation. When taking and placing materials, the locking component 200 can be pulled to disengage from the first loading part 101, enabling the second loading part 102 to be pulled out of the fixing frame 100 for convenient operation of staff to take and place materials.

[0033] Furthermore, the first loading part 101 includes a first bottom plate 101a arranged inside the fixing frame 100; the second loading part 102 includes a second bottom plate 102a arranged inside the fixing frame 100 and a top frame 102b arranged on the top of the second bottom plate 102a; wherein, the second bottom plate 102a can slide inside the fixing frame 100.

[0034] The first bottom plate 101a is fixedly arranged on the inner side of the fixed frame 100, and a frame member 101b is fixedly arranged on the top thereof for conveying materials. A support rod 102d is fixedly arranged between the second bottom plate 102a and the top frame 102b, so that the three of them form a conveying frame for conveying materials. The second bottom plate 102a is rotatably connected to rollers 102e on both sides, and the inner walls on both sides of the fixed frame 100 are provided with track grooves 103 corresponding to the rollers 102e, and both ends of the track grooves 103 do not penetrate the fixed frame. On both sides of the frame 100, the roller 102e is prevented from being separated from the fixed frame 100, so that the second loading part 102 is slidably connected to the fixed frame 100, and it can move more smoothly when being pulled out of the fixed frame 100. The locking component 200 is arranged on the top frame 102b. In daily transportation, the second loading part 102 can be fixed in position. Multiple groups of positioning columns are fixed on the top of the first bottom plate 101a and the second bottom plate 102a, so that the materials can be limited by the positioning columns during the movement.

[0035] Further, the moving member 201 is slidably arranged in the top frame 102b; the rotating member 202 includes a fan-shaped plate 202a rotatably connected to the top frame 102b, and a guide groove 202b provided in the fan-shaped plate 202a; wherein the moving member 201 can be plugged into the first bottom plate 101a, the top frame 102b is provided with a through groove 102c corresponding to the moving member 201, the fan-shaped plate 202a is sleeved with the moving member 201 through the guide groove 202b, and the guide groove 202b is provided with an oblique portion 202b-1; the through groove 102c penetrates the top frame 102b At the top, the moving part 201 includes a locking block 201a slidably arranged in the through slot 102c, and a fixing column 201b fixedly arranged on one side of the locking block 201a. A lifting spring 203 is fixedly arranged in the through slot 102c, and the top of the lifting spring 203 is fixedly connected with the locking block 201a. The lifting spring 203 pushes the locking block 201a to be plugged into the first bottom plate 101a. The first bottom plate 101a is provided with a locking groove 101c corresponding to the locking block 201a. The plugging of the locking block 201a and the first bottom plate 101a can fix the position of the second loading part 102.

[0036] The top of the locking block 201a is provided with an inclined surface. When the second loading part 102 moves to the fixed frame 100 to reset, the inclined surface can contact the first bottom plate 101a, so that the locking block 201a slides downward and shrinks. When it moves to correspond to the locking groove 101c, it is ejected by the lifting spring 203 and plugged into the first bottom plate 101a. The fan-shaped plate 202a is connected to a fixed shaft 202c, and a hinge seat is fixedly provided at the bottom of the top frame 102b. The fixed shaft 202c is rotatably connected to the hinge seat. The fan-shaped plate 202a is rotatably connected to the bottom of the top frame 102b, and a guide groove 202b is opened in the fan-shaped plate 202a. An inclined portion 202b-1 is provided in the guide groove 202b. One end of the inclined portion 202b-1 is close to the fixed shaft 202c, and the other end is far away from the fixed shaft 202c, so that the whole is inclined. A handle 204 is connected to the end of the fixed shaft 202c, and the fixed shaft 202c can be rotated by the handle 204, thereby driving the fan-shaped plate 202a to rotate.

[0037] In the initial state, when the second loading part 102 is fixed, the fixing column 201b is located at the end of the oblique part 202b-1 farther from the fixing axis 202c, and the locking block 201a is plugged into the first bottom plate 101a; when the second loading part 102 needs to be pulled out from the fixing frame 100, the handle 204 is held and rotated in the first direction, and the first direction is Figure 4 After the sector plate 202a is driven to rotate in the direction indicated by the middle arrow, the fixed column 201b moves to the end of the oblique portion 202b-1 that is closer to the fixed axis 202c. Due to the limitation of the locking block 201a by the through slot 102c, the locking block 201a moves downward and disengages from the locking slot 101c. At this time, the second loading portion 102 can be pulled outward to facilitate the placement of materials. When the second loading portion 102 needs to be reset, it can be pushed toward the fixed frame 100. The inclined surface on the top of the locking block 201a causes it to slide after being resisted, and is pushed out by the lifting spring 203 to plug into the first bottom plate 101a.

[0038] The sliding setting of the second loading part 102 allows the second loading part 102 to be pulled out of the fixing frame 100 when needed, and the feeding frame at the lower layer can have sufficient loading and unloading space, thereby ensuring the transportation efficiency and facilitating the workers to load and unload the materials.

[0039] In Example 2, since the AGV has a certain height, after the second loading part 102 is pulled out of the fixing frame 100, one end is suspended in the air without support, which causes the center of gravity of the entire device to shift, resulting in poor overall stability of the device.

[0040] Reference Figure 1-Figure 8This embodiment is different from the first embodiment in that it also includes a supporting component 300, which is arranged on one side of the second bottom plate 102a, and can support the second loading part 102 that slides out of the fixing frame 100; a connecting component 400, which is arranged between the supporting component 300 and the rotating member 202; the connecting component 400 is connected to the fixed shaft 202c, and when the fixed shaft 202c rotates to unlock the second loading part 102, the supporting component 300 can be driven to rotate through the connecting component 400, so that when the second loading part 102 slides out of the fixing frame 100, the supporting component 300 can support the second loading part 102 away from the fixing frame 100, thereby improving the overall stability of the device.

[0041] Furthermore, the guide groove 202b is provided with a positive arc portion 202b-2, which is connected to the end of the oblique portion 202b-1; in this embodiment, the end of the oblique portion 202b-1 away from the fixed shaft 202c is connected to the positive arc portion 202b-2, and the positive arc portion 202b-2 is a positive arc with the fixed shaft 202c as the center. When the locking block 201a is inserted into the first bottom plate 101a, the fixing column 201b is located at the end of the positive arc portion 202b-2. When the second loading part 102 is unlocked by rotating the fixed shaft 202c through the handle 204, the fixed shaft 202c has a rotation stroke, and during the rotation stroke, the fixed shaft 202c drives the supporting part 300 to rotate through the connecting part 400, so that the supporting part 300 is supported on the ground before the second loading part 102 is unlocked, thereby ensuring that the second loading part 102 can move smoothly and avoiding the device from tilting due to the second loading part 102 being pulled out of the fixing frame 100.

[0042] Furthermore, the supporting component 300 includes a rotating frame 301 arranged on one side of the second base plate 102a, and a universal wheel 302 arranged at the bottom end of the rotating frame 301; wherein, after the rotating frame 301 rotates, the universal wheel 302 can contact the ground; the connecting component 400 includes a follower 401, which is connected to the rotating member 202 and the rotating frame 301; wherein, the rotating member 202 drives the rotating frame 301 to rotate through the follower 401; the second base plate 102a is rotatably connected to the rotating frame 301 on the same side as the handle 204, and the universal wheel 302 is connected to the bottom of the rotating frame 301.

[0043] The follower 401 includes a first long rod 401a fixedly arranged on the outside of the fixed shaft 202c, and the two groups of rotating frames 301 are rotatably connected with a connecting rod 401c on the opposite side. The ends of the two groups of connecting rods 401c are rotatably connected through a limiter 402, and the connection between the two groups of connecting rods 401c is rotatably connected with a second long rod 401b, and the end of the second long rod 401b is rotatably connected with the first long rod 401a.

[0044] The limiting member 402 includes a long column 402a arranged at the end of the second long rod 401b, the ends of the two sets of connecting rods 401c are rotatably connected to the long column 402a, a long plate 402b is fixedly provided on one side of the second bottom plate 102a, a vertical groove 402c is opened in the long plate 402b, and the long column 402a is plugged into the vertical groove 402c.

[0045] When the second loading part 102 is fixed, the long column 402a is located at the top of the vertical slot 402c, and the ends of the two sets of rotating frames 301 are inclined toward each other, so that the universal wheels 302 are retracted and the rotating frames 301 are folded on one side of the second bottom plate 102a.

[0046] When the second loading part 102 is unlocked, the handle 204 is pulled to rotate in the first direction. At this time, the fixed column 201b moves in the arc portion 202b-2, and the rotating shaft drives the first long rod 401a to rotate, so that the second long rod 401b is driven to rotate. Since the end of the second long rod 401b is limited, the long column 402a moves downward, and the two sets of connecting rods 401c are driven to rotate to make the two sets of rotating frames 301 rotate, and then drive the universal wheel 302 to contact the ground to support one side of the second loading part 102. At this time, the fixed column 201b corresponds to the oblique portion 202b-1. The second loading part 102 can be unlocked by continuously rotating the fixed shaft 202c in the first direction.

[0047] Furthermore, it also includes a positioning component 500, which is connected to the rotating member 202 and can limit the rotation direction of the rotating member 202; the positioning component 500 is connected to the fixed shaft 202c, and since it can limit the rotation direction of the fixed shaft 202c, it can only rotate in the first direction, thereby ensuring that the supporting component 300 can be stably supported after rotation.

[0048] Furthermore, the supporting component 300 also includes a reset member 303 arranged on the rotating frame 301; a reset member 303 is provided between the rotating frame 301 and the second bottom plate 102a. In the present embodiment, the reset member 303 is a tension spring, and the two ends of the tension spring are respectively connected to the rotating frame 301 and the second bottom plate 102a. When the universal wheel 302 is supported by the ground, the tension spring is stretched. When the fixed shaft 202c is unlocked, the tension spring can pull the rotating frame 301 to rotate and reset, and then push the rotating shaft to reset through the follower 401.

[0049] The rest of the structure is the same as that of Example 1.

[0050] By setting the support component 300 to open first, the second loading part 102 can be stably supported when moving, avoiding the tilting of the device due to the movement of the second loading part 102. At the same time, the foldability of the support component 300 will not affect the transportation of the AGV cart, and can also reduce the wear of the universal wheel 302.

[0051] Example 3, reference Figure 1-Figure 10 This embodiment is different from the above embodiments in that: the positioning component 500 includes an adjusting portion 501 disposed on the rotating member 202, and a stopping portion 502 that abuts against the adjusting portion 501; wherein the stopping portion 502 limits the adjusting portion 501 to rotate only in the first direction.

[0052] In this embodiment, the adjusting portion 501 is a ratchet gear, which is arranged at the end of the fixed shaft 202c away from the handle 204. A hinge seat is provided at the bottom of the top frame 102b. The stop portion 502 includes a connecting shaft 502a rotatably connected to the hinge seat. A rotating tooth 502b is fixedly connected to the connecting shaft 502a. The rotating tooth 502b is arranged on one side of the adjusting portion 501. Due to the engagement between the rotating tooth 502b and the adjusting portion 501, the adjusting portion 501 can only rotate in the first direction, that is, the fixed shaft 202c can only rotate in the first direction. A spring sheet 502c is fixedly provided on the hinge seat. The spring sheet 502c resists the engagement between the rotating tooth 502b and the adjusting portion 501. Through the cooperation between the rotating tooth 502b and the adjusting portion 501, the support component 300 can be fixed after being opened.

[0053] At the same time, in the present embodiment, the adjusting portion 501 is sleeved with the fixed shaft 202c through the pressing member 600, the pressing member 600 includes a limiting rod 601 slidably provided in the fixed shaft 202c, and the limiting rod 601 extends out of the outside of the handle 204, one end of the limiting rod 601 away from the handle 204 is fixedly connected to the adjusting portion 501, the fixed shaft 202c is provided with a limiting groove 202d corresponding to the limiting rod 601, and the limiting groove 202d extends to the inside of the handle 204, one end of the limiting rod 601 away from the adjusting portion 501 is fixedly connected with a button cover 602, a long groove corresponding to the button cover 602 is provided in the handle 204, and the long groove leaves a margin for the button cover 602 to slide, a resistance spring 603 is sleeved on the outside of the limiting rod 601, the resistance spring 603 is located in the button cover 602, and its two ends respectively resist the inner wall of the button cover 602 and the end wall of the long groove.

[0054] When the second loading part 102 needs to be folded up, the button cover 602 is pressed to allow the limiting rod 601 to drive the adjusting part 501 to slide and disengage from the rotating tooth 502b. At this time, since the fixed shaft 202c loses its limit, the two sets of reset parts 303 instantly pull the rotating frame 301 to rotate and reset. At the same time, the fixed shaft 202c rotates and resets, and the locking block 201a extends out of the through slot 102c. At this time, the two sets of supporting parts 300 are folded on the side of the second bottom plate 102a.

[0055] In this embodiment, the guide groove 202b is also provided with a straight portion 202b-3, the top end of which corresponds to the arc portion 202b-2, so that when the locking block 201a is located at the end of the arc portion 202b-2, it has a downward movement stroke. When the supporting component 300 is retracted, it continues to push the second loading part 102 to move toward the fixed frame 100. Due to the setting of the straight portion 202b-3, the locking block 201a can still be resisted by the first base plate 101a and plugged into it, thereby completing the fixation of the second loading part 102.

[0056] The rest of the structure is the same as that of Example 2.

[0057] By disposing the positioning component 500 and the pressing component 600 , the supporting component 300 can be locked and unlocked, so that the supporting component 300 can play a more stable supporting effect.
