Description

Technical Field

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

[0002] In the existing technology, AGV mobile guided vehicles are widely used in mechanical equipment, underwater exploration, warehousing and logistics, pipeline cleaning and catering industries. In the existing technology, AGV carts are guided by optical or electromagnetic processing equipment to follow a specified path. The software facilities inside the AGV cart usually need to include a camera component for collecting images, a drive component, an antenna receiving and transmitting component, a drive component and a sensor component.

[0003] For example, the technical solution with the publication (announcement) number CN104787016A discloses “an automatic guided vehicle”, which includes a vehicle head, a first sensor, a second sensor, and a control system, and mainly relies on the sensor sensing distance to realize the automatic guidance function.

[0004] Although existing automated guided vehicles can travel along designated routes, they may often be blocked by obstacles, resulting in collisions. Therefore, most automated guided vehicles are also equipped with anti-collision mechanisms on the vehicle body. However, existing anti-collision mechanisms are usually fixed to the vehicle body and cannot be removed. Once the anti-collision mechanism is damaged by a collision, it is usually not replaceable, resulting in inconvenience in subsequent use.

[0005] Therefore, in order to solve the above problems, it is necessary to develop an AGV automatic guided vehicle with a reasonable anti-collision mechanism design and a corresponding replaceable anti-collision mechanism. Summary of the Invention

[0006] The purpose of this utility model is to provide an AGV automatic guided vehicle to address the shortcomings of the existing technology; its technical solution is as follows:

[0007] An AGV (Automated Guided Vehicle) includes a frame, in which a signal receiving and transmitting antenna, a camera mechanism, a drive mechanism, a sensor, and an automatic guidance processor are installed; the frame is also equipped with an anti-collision mechanism, which includes an inner groove provided on the side wall of the frame, the inner groove being arranged transversely and correspondingly recessed toward the interior of the frame, and the inner grooves being evenly spaced on the side wall of the frame;

[0008] A detachable inner rod is installed in each inner groove, and a mounting seat is provided at the other end of the inner rod. The mounting seat is located on the outside of the frame, and a divergent petal-shaped anti-collision strip is installed on each mounting seat through a spring hinge assembly. When the anti-collision strip collides with foreign objects, it can be squeezed inward and reset under the action of the spring hinge assembly.

[0009] Furthermore, the inner rod and the inner groove are arranged to be detachably mounted by threads; the inner rod and the inner groove are designed to be detachable structures, and threaded connection is usually a relatively common detachable connection structure in the prior art. Therefore, the connection method can be designed to be a threaded connection; however, this method takes a long time to tighten when replacing, which is time-consuming.

[0010] Furthermore, a semicircular slot is provided on the sidewall of the inner groove; a corresponding semicircular block is provided on the inner rod, and the inner rod is detachably mounted via the slot and block. This device also provides a structural combination of the slot and block to achieve detachable connection. Because both the slot and block are designed in a semicircular shape, the inner rod can be pulled out by applying external force from the outside, making replacement more convenient and quick.

[0011] Furthermore, the frame includes an upper frame and a lower frame, both of which are arranged as circular frame structures, the upper frame and the lower frame are detachable and installable, and the inner groove is arranged on the side wall of the lower frame; the device designs the frame as an upper and lower frame structure, which is convenient for subsequent disassembly, installation, maintenance, etc. of the trolley, which is very convenient.

[0012] Furthermore, there are six inner grooves evenly spaced on the side wall of the lower frame; the location of the anti-collision strip needs to be reasonably designed, and the spacing cannot be too large, otherwise there is still a risk of collision. Therefore, six inner grooves are designed to be more reasonable and effective in preventing collisions.

[0013] Furthermore, five anti-collision bars are installed on each mounting seat, and the installation angles of the five anti-collision bars on the mounting seat are the same, and the anti-collision bars are configured as rubber strips or plastic strip structures; the anti-collision bars on the mounting seat are petal-shaped structures, and the overall structure is a divergent structure, which can better protect the frame.

[0014] Furthermore, a downwardly recessed spring groove is provided at the upper end of the upper frame of the frame, and a loading plate is provided above the upper frame. A limiting cylinder is provided at the lower end of the loading plate, and the lower end of the limiting cylinder is open and extends into the spring groove accordingly, and a buffer spring is also installed between the bottom of the spring groove and the lower end surface of the loading plate; the spring groove and spring part designed in this device are mainly used to eliminate the buffer force, and the designed limiting cylinder is used for limiting protection.

[0015] Furthermore, there are three spring grooves on the upper frame that are evenly distributed in the circumferential direction, and the loading plate is configured as a circular plate structure, and a fence is also provided at the edge of the loading plate; the loading plate designed in this device is mainly used for transporting items, and items can be directly placed on the loading plate, and a fence is provided at the edge to prevent items from falling.

[0016] Beneficial effects: The utility model has the following beneficial effects:

[0017] 1) Specifically, the device is designed with an inwardly concave inner groove on the frame, an inner rod is installed in the inner groove, a mounting seat is provided on the inner rod, and the anti-collision strip is correspondingly provided on the mounting seat, and the inner rod is correspondingly provided with a detachable structure. With this design, each inner rod and the corresponding anti-collision strip can be removed and replaced to prevent damage and irreplaceability, thereby affecting the anti-collision effect. In addition, the inner rod of the device can be designed to be disassembled in two ways: one is a threaded connection, and the other is a slot and strip connection, which can be installed according to actual usage.

[0018] 2) The anti-collision bar in this device is specifically set on the mounting base via a spring hinge assembly. The spring hinge assembly is elastic, and the anti-collision bar is squeezed inward after hitting an object, but can also be reset under the action of the spring hinge assembly. The structure of the spring hinge assembly is prior art, and therefore its structure is not described in detail. The anti-collision bar in this device is arranged in a circular manner, shaped like petals, and is arranged at an angle, which can effectively prevent collisions, is more structurally reasonable, and is easy to use.

[0019] 3) In this device, the overall frame is divided into an upper frame and a lower frame. The upper and lower frames are detachable and a loading plate is provided above the upper frame. The loading plate can be used to place items. The lower frame is also provided with a downwardly concave spring groove. A buffer spring is installed in the spring groove. The buffer spring is installed upward in correspondence with the lower frame. The buffer spring can effectively offset the shaking of the trolley during movement and the shaking caused by emergency stop. A limiting cylinder is also provided downward on the loading plate, which extends into the spring groove to prevent the loading plate itself from moving, thereby playing a limiting role and making the structure more reasonable.
