Description

Technical Field

[0001] The utility model relates to the technical field of AGV, and more specifically, to a highly stable AGV vehicle navigation frame. Background Art

[0002] It is known that the navigation sensor is the "eye" of the AGV body, and its operation accuracy directly affects the positioning of the AGV body and the accuracy of the running trajectory, so this component is an important part of the AGV body; in view of the importance of this component, the prior art often provides a bracket to support and protect the navigation sensor; among them, the existing navigation bracket usually has two layout modes: one is to be designed on the gantry and connected to the gantry; the other is to be set at the front of the body and separated from the gantry; because the navigation sensor has a certain height requirement, in order to reduce the occlusion of the navigation laser scanning when the navigation sensor is running, the navigation bracket needs to be made very long, and some supporting columns are made of a single rectangular tube, and the electrical accessories are placed on the top, and the wiring harness passes through the rectangular tube; it can be seen that the existing technical scheme has the following problems: 1. If the navigation bracket is connected to the top of the gantry, when the forklift is lifted, lowered or unloaded, the gantry will produce a large shake because it is the lifting mechanism of the goods, thereby affecting the navigation sensor located at the high part of the gantry, and the greater the shaking amplitude, the inaccurate positioning of the vehicle body will be caused, and the running trajectory of the vehicle body will be distorted;

[0003] 2. If the navigation bracket is set at the front of the vehicle, when the vehicle starts, stops or avoids obstacles in an emergency, the navigation bracket is too long and the rigidity of the single rectangular tube as the support column is insufficient, so the electrical accessories placed on the top of the support column will easily shake greatly, affecting the actual effect of the navigation sensor;

[0004] 3. If a single rectangular tube is used as the navigation bracket, multiple wire harnesses can only pass through the single rectangular tube, making it difficult to produce, debug and repair the wire harnesses. Too many electrical accessories are placed on the vehicle body. When facing the diverse needs of different customer groups and the customer's demand for expanded electrical accessories, the entire bracket needs to be replaced. It can be seen that the existing navigation brackets have poor product compatibility and are not flexible enough.

[0005] Therefore, in order to solve the problem that the navigation bracket is easily shaken by the movement of the vehicle body, a highly stable AGV vehicle navigation bracket is proposed as a further improvement. Utility Model Content

[0011] Furthermore, the shapes of the front and back sides of the bracket assembly are both set to be isosceles triangle shapes, and the navigation lower cover assembly is fixedly installed at the apex angle of the isosceles triangle of the bracket assembly.

[0012] Furthermore, the electrical box assembly includes: a wire dust ring, an electrical fixing box, a wireless antenna, an antenna insulation plate, a display screen fixing plate, a display screen and electrical control buttons;
