DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The trolley adopts a relatively mature trolley in the prior art, and its shape is similar to that in the present application, wherein the charging port of the trolley is arranged at the front and rear ends. The principle of the trolley will not be described in detail later. In order to facilitate the AGV trolley body 1 to transport objects more stably, a loading tray 2 is detachably arranged at the upper end of the AGV trolley body 1. The front and rear ends of the loading tray 2 are symmetrically slidably connected with two groups of first sliders 4, a total of four, two first sliders 4 at the front and rear ends, and the two first sliders 4 are connected to each other. An elastic plate 23 is fixedly connected thereto, and the elastic plate 23 can be bent to the extent shown in the figure. The front and rear ends of the loading tray 2 can be raised and lowered with baffles 35. After the elastic plate 23 is hit or hits the wall, the baffle 35 will be driven to rise synchronously, even if the distance of the inertial movement of the goods is blocked. In order not to block the charging port, the elastic plate 23 can be stored to further store space. A driving mechanism is provided in the loading tray 2 for driving the first slider 4 to slide toward the center of the loading tray 2. In addition, the driving mechanism can lock the loading tray 2 on the AGV trolley body 1.

In order to ensure that the second ball 29 can move in a straight line toward the center of the AGV trolley body 1, the first rectangular frame 26 and the second rectangular frame 27 are slidably connected to the front and rear ends of the loading plate 2 at one end away from the first ball 25. Through this setting, no matter in which direction the elastic plate 23 is impacted and squeezed, it can drive the first rectangular frame 26 or the second rectangular frame 27 to move, and drive the second ball 29 to move, thereby driving the baffle 35 to rise, thereby blocking the goods on the AGV trolley body 1.

[0032] Specific, combined Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the upper and lower end surfaces of the second rectangular frame 27 are fitted with a U-shaped rod 30, the U-shaped rod 30 is placed horizontally, and the ends of the U-shaped rod 30 are rollingly connected to the upper and lower halves of the second ball 29, the upper and lower halves of the second ball 29 pass through the ends of the U-shaped rod 30 and roll in the second ball groove 28 set in the first rectangular frame 26, in order to ensure the stability between the first rectangular frame 26, the second rectangular frame 27 and the U-shaped rod 30, the upper and lower end surfaces of the U-shaped rod 30 are respectively fitted with the upper and lower end surfaces of the inner side of the first rectangular frame 26, and the upper and lower end surfaces of the inner side of the U-shaped rod 30 are respectively fitted with the upper and lower end surfaces of the second rectangular frame 27, to ensure that the force of the elastic plate 23 after being hit can be stably transmitted, One end of the U-shaped rod 30 away from the first ball 25 is slidably connected to a second rectangular groove 32 opened in the front-to-rear direction of the end of the loading tray 2 and a wedge-shaped plate 34 is fixedly connected to the end. The inclined surface of the wedge-shaped plate 34 at one end of the U-shaped rod 30 is higher than that of the other end and the upper inclined surface of the wedge-shaped plate 34 always fits the lower end of the baffle 35. A tension spring 36 is fixedly connected between the lower end of the baffle 35 and the loading tray 2. The wedge-shaped plate 34 moves toward the center of the loading tray 2 to drive the baffle 35 to rise, and is used to drive the baffle 35 to fall under the action of the tension spring 36, so that the surface of the loading tray 2 is flat when loading, which is convenient for manual or machine loading, but the loaded goods cannot exceed the position of the two baffles 35.

[0033] Specific, combined Figure 2 As shown, a mounting groove 5 is opened in the loading plate 2, a mounting rod 6 is fixedly connected to the middle of the mounting groove 5, a transmission rod 7 is fixedly connected to the inner side surface of the first slider 4, and a second circular plate 22 is fixedly connected to the end of the transmission rod 7 away from the first slider 4, wherein the second circular plates 22 at the ends of the four transmission rods 7 are rotatably connected to the outer side surface of the mounting rod 6 in sequence from top to bottom without interfering with each other's rotation.

[0034] Specific, combined Figure 2 , Figure 4 and Figure 5 As shown, the driving mechanism includes:

[0035] A pull rod 9 is slidably connected to the left and right sides of the loading tray 2 in the left and right directions. A rectangular through hole is provided in the loading tray 2, and the pull rod 9 is slidably connected in the rectangular through hole;

[0036] The connecting rod 8 connected to the end of the pull rod 9 toward the installation rod 6 is rotated, and the end of the connecting rod 8 away from the pull rod 9 is rotated and connected to the surface of the transmission rod 7;

[0037] A driving component is used to drive the pull rod 9 to slide, wherein the driving component can drive the pull rod 9 to move back to the mounting rod 6, and the driving component drive is divided into two sections in total. The first section is used to drive the first slider 4 to move toward the middle of the loading tray 2, and the second section is used to unlock the loading tray 2 and the AGV trolley body 1.

[0038] Specific, combined Figure 4 and Figure 5 As shown, in order to realize the installation of the first threaded rod 10, a first rectangular groove 11 is longitudinally opened at the end of the pull rod 9 away from the mounting rod 6, and a rectangular block 12 is fixedly connected to the loading plate 2 in the first rectangular groove 11. The rectangular block 12 is located in the first rectangular groove 11 and does not interfere with the movement of the pull rod 9. A mounting shaft 13 is fixedly connected to the side of the rectangular block 12 away from the mounting rod 6. The first threaded rod 10 is rotatably connected to the outer side surface of the mounting shaft 13, and the outer side surface of the first threaded rod 10 is threadedly connected to the inner side surface of the pull rod 9 to realize the driving sliding of the pull rod 9.

[0039] Specific, combined Figure 2 , Figure 4 and Figure 5 As shown, the drive assembly includes:

[0040] The motor 14 is fixedly connected to the left and right sides of the loading tray 2. In order to save space, notches 21 are provided on the left and right sides of the loading tray 2 for installing the motor 14. The motor 14 adopts a servo motor, and the movement of the pull rod 9 is conveniently controlled by controlling the number of rotations.

[0041] The second threaded rod 15 fixedly connected to the output shaft of the motor 14 has the same thread and rotation direction as the first threaded rod 10, and can be considered as a threaded rod with a section removed from the middle to form the first threaded rod 10 and the second threaded rod 15;

[0042] An internal threaded rod 17 is threadedly connected to the outer side of the first threaded rod 10 and the second threaded rod 15, and the internal threaded rod 17 is driven and moved by thread transmission;

[0043] The middle part of the inner side surface of the internal threaded rod 17 is rotatably connected with the first circular plate 19, so that the internal threaded rod 17 does not interfere with the rotation of the first circular plate 19 when moving;

[0044] The polygonal rod 18 is fixedly connected to the middle of the first circular plate 19. When the first circular plate 19 can rotate, it does not interfere with the rotation of the polygonal rod 18. Then, the movement of the internal threaded rod 17 can also drive the movement of the polygonal rod 18.

[0045] The first threaded rod 10 and the second threaded rod 15 have opposite ends symmetrically provided with polygonal grooves 16 for inserting the polygonal rod 18, so that the polygonal rod 18 can move in the polygonal grooves 16. It should be noted that the polygonal rod 18 is always located in the polygonal grooves 16 provided in the second threaded rod 15, wherein the end of the polygonal rod 18 facing the mounting rod 6 is chamfered to facilitate the polygonal rod 18 to reset the internal threaded rod 17, and the chamfered end is longer than the end face of the internal threaded rod 17, so that the internal threaded rod 17 is first disengaged from the meshing with the first threaded rod 10, and then the polygonal rod 18 then disengages from the cooperation with the polygonal groove 16 on the first threaded rod 10. It should be noted that when the polygonal rod 18 disengages from the polygonal groove 16 on the first threaded rod 10 again, the pull rod 9 is not limited by the loading plate 2 and the rectangular block 12, that is, when the first threaded rod 10 is rotated, the pull rod 9 can also be driven to move. The purpose of such a setting is that when the polygonal rod 18 disengages from the polygonal groove 16 on the first threaded rod 10 again, the first slider 4 can already pull the elastic plate 23 to a position closer to the loading plate 2, but not the extreme position.

[0046] Specific, combined Figure 6 As shown, in order to realize the easy fixation of the loading tray 2 on the AGV trolley body 1, a plug plate 20 is fixedly connected to the lower end of the internal threaded rod 17, and the plug plate 20 is L-shaped. Plug holes for plugging in the plug plate 20 are provided on the left and right sides of the AGV trolley body 1, that is, when the driving component drives the pull rod 9 to move, it is used to unlock and lock the loading tray 2 on the AGV trolley body 1, and a positioning block 39 is fixedly connected to the lower end of the loading tray 2, and a positioning hole for plugging in the positioning block 39 is provided on the upper end of the AGV trolley body 1.

[0047] Specific, combined Figure 2 and Figure 4 As shown, a rack 33 is fixedly connected to one side of the U-shaped rod 30, and a gear 38 is rotatably connected to the lower end of the mounting rod 6. The gear 38 and the rack 33 are meshed, so that the baffles 35 at the front and rear ends of the AGV body 1 can be lifted and lowered simultaneously when the front end is hit.

[0048] Specific, combined Figure 2 As shown, rectangular slide grooves 37 are symmetrically opened at the front and rear ends of the loading plate 2, and a second slider 31 is slidably connected in the rectangular slide groove 37. The ends of the first rectangular frame 26 and the second rectangular frame 27 away from the first ball 25 are respectively rotatably connected to the corresponding second slider 31, so as to achieve stability of the first rectangular frame 26 and the second rectangular frame 27 when moving.

[0049] Working principle: When installing the loading plate 2, first insert the positioning block 39 into the positioning hole, then control the motor 14 to rotate forward, drive the second threaded rod 15 to rotate, the second threaded rod 15 drives the internal threaded rod 17 to move, the internal threaded rod 17 drives the plug plate 20 to insert into the plug hole, and at the same time drives the polygonal rod 18 to insert into the polygonal groove 16 in the first threaded rod 10, so that the motor 14 drives the second threaded rod 15 and the first threaded rod 10 to rotate synchronously, and then drives the pull rod 9 to move toward the installation rod 6, and the connecting rod 8 will push the transmission rod 7 to move, so that the second circular plate 22 rotates along the axis of the installation rod 6, and then squeezes the elastic plate 23 to Figure 1 Figure 4 The status shown in ;

[0050] When the elastic plate 23 is hit, it can drive both ends of the first rectangular frame 26 or the second rectangular frame 27 to slide simultaneously, and push the second ball 29 and the U-shaped rod 30 to move toward the mounting rod 6, so that the inclined surface of the wedge plate 34 pushes the baffle 35 to move upward, and at the same time the rack 33 will drive the gear 38 to rotate, so that the baffle 35 at the other end moves upward at the same time to block the goods on the loading tray 2. When the elastic plate 23 is restored, the baffle 35 will automatically slide down under the action of the tension spring 36, so as to facilitate the subsequent transportation or resetting of the goods.
