Description

Technical Field

[0001] The utility model relates to the technical field of automatic guided vehicles, in particular to an intelligent AGV vehicle. Background Art

[0002] AGV is an automatic guided vehicle, also called an automatic guided transporter or automatic guided carrier. It is an industrial vehicle that loads goods automatically or manually, and automatically drives or tows a cargo trolley to a designated location along a set route, and then loads and unloads goods automatically or manually. It is usually powered by batteries.

[0003] However, when the existing intelligent AGV cart is in use, when cargo that exceeds the cart's carrying weight is placed on the cart, the cart cannot know whether the cargo is overweight, so the cart runs in an overloaded state for a long time, which can easily shorten the service life of the cart. In addition, the existing carts are usually flatbed carts, and when high cargo is stacked on the top of the cart, the cargo is more likely to tilt forward or slide backward due to the sudden braking of the cart during the travel of the cart, causing the cargo loaded on the cart to fall off during the transportation process, which is not conducive to keeping the cargo on the cart in a stable state during the transportation process of the cart. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent AGV vehicle to solve the problems raised in the above background technology.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4As shown, the intelligent AGV trolley of this embodiment includes a side box 1, a groove 3 is opened at the top of the side box 1, a clamping rod 9 is arranged inside the groove 3, a first flap 2 is fixedly connected to the middle of the clamping rod 9, a bracket 4 is fixedly connected to one side wall of the side box 1, a flat plate 5 is arranged on the top of the bracket 4, a pressure rod 18 is fixedly connected to the middle of the bottom end of the flat plate 5, a spring 17 is arranged on the outer movable sleeve of the pressure rod 18, a button switch 20 is arranged at the bottom of the pressure rod 18, contact blocks 21 are fixedly connected to both sides of the bottom end of the flat plate 5, driving wheels 16 are installed on both sides of the bottom end of the bracket 4, a rotating rod 6 is arranged on one side of the bracket 4, a second flap 7 is fixedly connected to the middle of the rotating rod 6, an auxiliary wheel 14 is installed at the bottom end of the side box 1, a lithium battery 15 is clamped at the bottom of the inner side of the side box 1, and rubber pads 8 are fixedly connected to the tops of the first flap 2 and the second flap 7.

[0024] Specifically, the interior of the side box 1 is also equipped with an automatic guiding system and various sensors and other electrical components required for the normal operation of the intelligent trolley. The groove 3 can store and store the unused first flap 2 to improve the flexibility of the first flap 2 when in use. The card rod 9 can drive the first flap 2 to flip up from the groove 3, thereby achieving the fit of the goods on the trolley to increase the stability of the goods on the trolley. The bracket 4 is divided into two parts, with a gap in the middle, which is convenient for placing the goods on the bracket 4. The top of the flat plate 5 is higher than the top of the bracket 4, so that when the goods are placed on the bracket 4, they will first contact the flat plate 5, so that the flat plate 5 can be pressed down by the goods, causing the pressure rod 18 and the spring 17 on the outer wall of the pressure rod 18 to deform, thereby achieving the pressure rod 18 to touch the button switch 20, which is beneficial to timely power off the trolley when it is overloaded, and reducing the probability of the trolley running overloaded for a long time. The pressure rod 18 is located directly above the button switch 20 and can be between the flat plate 5 and the spring 17 Under the action, the button switch 20 is pressed. The function of the spring 17 is mainly to bear the downward force of the flat plate 5, so that the flat plate 5 can be reset when no force is applied. The bottom surface of the contact block 21 is an arc surface, and the radius of the arc surface is the same as the radius of the driving wheel 16, so that after the flat plate 5 is pressed down to a suitable position, the contact block 21 will be tightly attached to the top surface of the driving wheel 16, and the driving wheel 16 will be locked, so that the trolley remains stationary after the power is cut off, thereby prompting the staff to unload the overloaded goods from the trolley, and the second flap 7 can support the surface of the goods on the trolley, reduce the probability of the goods on the trolley sliding back when the trolley brakes suddenly, thereby increasing the stability of the goods on the trolley during transportation. The driving wheel 16 is an electric wheel driven by electricity, which can rotate automatically after power is turned on. The auxiliary wheel 14 makes the trolley more stable when moving forward, and the rubber pad 8 is a silicone pad 8 with a rough surface, so that the first flap 2 and the second flap 7 can fit more closely with the goods stacked on the trolley.

[0025] Furthermore, a first sprocket 10 is sleeved on one end of the clamping rod 9, a chain 11 is meshed on the outside of the first sprocket 10, a second sprocket 12 is meshed on the inside of the chain 11, a first motor 13 is installed inside the side box 1, and the first sprocket 10 is driven by the first motor 13, so that the clamping rod 9 can drive the first flap 2 to flip up or down in the groove 3, thereby facilitating user operation.

[0026] Furthermore, the second sprocket 12 is sleeved and connected with the output end of the first motor 13, and the clamping rod 9 is rotatably connected with the groove 3 through the first sprocket 10 and the second sprocket 12. The second sprocket 12 enables the first sprocket 10 to be linked with the output end of the first motor 13, thereby realizing the driving of the first flap 2 by the clamping rod 9, so that the first flap 2 can be smoothly rotated to a position that fits the goods.

[0027] Furthermore, a cavity is opened in the middle of the bracket 4, and an inner box 19 is fixedly connected to the bottom of the inner side of the cavity. The bottom end of the spring 17 is fixedly connected to the top of the inner box 19. The interior of the inner box 19 is hollow, and the inner box 19 can protect the internal button switch 20.

[0028] Furthermore, the pressure rod 18 is movably connected to the inner box 19, and the flat plate 5 is movably connected to the bracket 4 through the spring 17 and the pressure rod 18. The flat plate 5 can contact the goods before the bracket 4, so that the weight of the goods can be pressed on the flat plate 5, which is beneficial for the flat plate 5 to press the weight of the goods that exceeds the bearing range of the trolley on the pressure rod 18, thereby realizing the triggering of the button switch 20 by the pressure rod 18.

[0029] Furthermore, a second motor 22 is fixedly installed inside the bracket 4, and the output end of the second motor 22 is engaged with one end of the rotating rod 6. The rotating rod 6 is rotatably connected to the bracket 4 through the second motor 22. The second motor 22 will drive the rotating rod 6 to rotate after the power is turned on, so that the second flap 7 can be rotated from a horizontal state to a vertical state, thereby facilitating the second flap 7 to fit the cargo on the trolley.

[0030] Furthermore, the lithium battery 15 is electrically connected to the button switch 20, the first motor 13 and the second motor 22 respectively. The button switch 20 is fixedly installed inside the inner box 19. The lithium battery 15 also supplies power to the drive wheel 16, so that the drive wheel 16 remains stationary after power failure, so that the trolley stays in place after placing overweight cargo, which can prompt the operator to move the overweight cargo off the top of the trolley.

[0031] The method of using this embodiment is as follows: when placing goods on the intelligent AGV trolley, the bottom of the goods will first contact the flat plate 5 on the bracket 4. At this time, the flat plate 5 will bear the weight of the goods, so that the flat plate 5 slides down along the top of the bracket 4, driving the pressure rod 18 in the middle of the bottom end of the flat plate 5 to slide down, and at the same time, the spring 17 on the outside of the pressure rod 18 will be compressed, and when the weight of the placed goods exceeds the carrying capacity of the trolley, the bottom end of the pressure rod 18 will slide into the inner box 19 and trigger the button switch 20 in the inner box 19, so that the button switch 20 cuts off the power supply of the lithium battery 15, so that the lithium battery 15 stops supplying power to the driving wheel 16, and at the same time, the contact block 21 at the bottom end of the flat plate 5 will contact and fit with the top surface of the driving wheel 16, so that the driving wheel 16 remains stationary. At this time, the trolley will stop in place and will not move. When the heavy cargo is moved away from the top of the trolley, the pressure rod 18 and the contact block 21 at the bottom of the flat plate 5 will be separated from the button switch 20 and the driving wheel 16 respectively, so that the lithium battery 15 can supply power to the driving wheel 16 again. At this time, the trolley returns to normal. When the weight of the placed cargo does not cause the pressure rod 18 to touch the button switch 20, the first motor 13 and the second motor 22 can be started, so that the first motor 13 drives the first sprocket 10 and the second sprocket 12 to rotate, and drives the clamping rod 9 to rotate, so that the first flap 2 is flipped out from the groove 3 at the top of the side box 1, so that the first flap 2 is attached to the front of the cargo. At the same time, the second motor 22 will drive the rotating rod 6 to rotate the second flap 7 to a vertical position, so that the second flap 7 is attached to the back of the cargo, so that the higher stacked cargo can be stably clamped during the transportation of the trolley.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
