[0025] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0026] See also Figure 1-6 The utility model provides a technical solution: an unmanned vehicle grabbing and delivering mechanism, comprising a main body 1, and two box doors 2 are slidably installed on one side of the main body 1.

[0027] Specifically, the outer surface of the main body 1 is provided with second grooves 18 on both upper and lower sides. The side walls of the door 2 are fixed with slide bars on both upper and lower sides, and the slide bars are slidably installed in the second grooves 18.

[0028] A movable plate 17 is slidably provided at the inner bottom end of the main body 1 .

[0029] Specifically, first grooves 4 are formed on both sides of the inner bottom surface of the main body 1 , and connecting blocks are fixedly connected to both sides of the lower end surface of the movable plate 17 , and the connecting blocks are slidably installed inside the first grooves 4 .

[0030] A linkage assembly is provided between the movable plate 17 and the door 2 .

[0031] The linkage assembly includes a first screw rod 5, a first gear 6, a first motor 15, and a second rack 19. The first screw rod 5 is rotatably mounted within the first groove 4 and is threadedly connected to the connecting block. The first motor 15 is fixedly mounted within the first groove 4 on the side away from the door 2. The output shaft of the first motor 15 is fixedly connected to the first screw rod 5. The second rack 19 is fixedly mounted to the side wall of the door 2. The first gear 6 is fixedly mounted on the end of the first screw rod 5 facing away from the first motor 15, and the first gear 6 meshes with the second rack 19.

[0032] A second sliding groove 14 is formed on the movable plate 17 . Moving blocks are slidably mounted on both sides of the second sliding groove 14 . Support blocks 16 are fixed to the moving blocks.

[0033] The first grabbing claws 7 are fixedly connected to the ends of the opposite surfaces of the two support blocks 16 away from the second sliding slot 14 .

[0034] The support blocks 16 are each provided with a first sliding groove 9 .

[0035] Slide blocks 11 are slidably mounted inside the first sliding grooves 9 , and second grabbing claws 10 are movably mounted on the slide blocks 11 .

[0036] Specifically, a second screw rod 8 is rotatably mounted within the first chute 9 and is threadedly connected to the slider 11. A slide rod 22 is slidably mounted on each slider 11 and extends through the slider 11. One end of the slide rod 22 is fixedly connected to the second grabbing claw 10. A spring 23 is fixedly connected to the opposing surface of the slider 11 and the second grabbing claw 10 and is sleeved on the outside of the slide rod 22.

[0037] The support blocks 16 are each provided with a driving assembly for driving the slider 11 to move.

[0038] The driving assembly includes a second gear 12 and a first rack 13 . The first rack 13 is fixedly mounted on the side wall of the movable plate 17 . The second gear 12 is fixedly mounted on one end of the second screw rod 8 . The second gear 12 is meshed with the first rack 13 .

[0039] In order to drive the two support blocks 16 to move, a second motor 20 is fixedly installed on the side wall of the movable plate 17, and a third screw rod 21 is rotatably installed inside the second slide groove 14. The outer surface of the third screw rod 21 has threads with opposite rotation directions on both sides, and the movable blocks on the two support blocks 16 are respectively threadedly connected to the two sides of the third screw rod 21.

[0040] Working principle:

[0041] During use, when the main body 1 needs to transport items, the items to be transported are placed in a certain area, the main body 1 moves to the vicinity of the items to be transported, the first motor 15 is started, the output shaft of the first motor 15 rotates the first screw rod 5, the first screw rod 5 rotates the first gear 6, and the first gear 6 engages with the second rack 19 to move the box door 2.

[0042] It should be noted that the output shafts of the two first motors 15 rotate in opposite directions, causing the two first screw rods 5 to rotate in opposite directions, and thus the two first gears 6 to rotate in opposite directions, causing the two doors 2 to move away from each other. The threads in the two connecting blocks rotate in opposite directions, causing the rotation of the two first screw rods 5 to drive the two connecting blocks to move synchronously in the same direction.

[0043] The first screw rod 5 drives the movable plate 17 to move along the first groove 4 through the connecting block, and further drives the supporting block 16 to move so that the first grabbing claw 7 and the second grabbing claw 10 move outward from the main body 1 to prepare for grabbing materials.

[0044] The second motor 20 is started, and the output shaft of the second motor 20 rotates the third screw rod 21. The rotation of the third screw rod 21 drives the two support blocks 16 to move toward each other through the two moving blocks, so that the first grabbing claw 7 and the second grabbing claw 10 approach the object. When the support block 16 moves, it drives the second gear 12 to move. The second gear 12 engages with the first rack 13, thereby causing the second screw rod 8 to rotate. The second screw rod 8 causes the slider 11 to approach the first grabbing claw 7 along the first slide groove 9. The movement of the slider 11 drives the second grabbing claw 10 to move, thereby grabbing the object.

[0045] By setting the slide rod 22 and the spring 23, when the first grabbing claw 7 and the second grabbing claw 10 clamp an object, the spring 23 contracts and causes the slide rod 22 to slide on the slider 11, so that the clamping process has a buffering effect, avoiding damage to the object caused by excessive clamping force.

[0046] After the first grabbing claw 7 and the second grabbing claw 10 grab an item, the first motor 15 is started, and the output shaft of the first motor 15 rotates in reverse, causing the first screw 5 to drive the movable plate 17 to move along the first groove 4. The movable plate 17 drives the support block 16 to move, thereby facilitating the first grabbing claw 7 and the second grabbing claw 10 to move into the main body 1. The first screw 5 rotates the first gear 6, which engages with the second rack 19 to move the door 2 closer to the main body 1, thereby closing the door 2.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
