Description
Technical Field
[0001] This application relates to a mobile robot chassis, belonging to the field of vehicle engineering technology, and particularly to an all-terrain chassis load-bearing body. Background Technology
[0002] All-terrain mobile robots are a type of robot capable of moving freely across various complex terrains, demonstrating strong potential in many application scenarios. Currently, wheeled mobile robot chassis include monocoque and non-monocoque designs. Monocoque designs integrate the body and chassis, while non-monocoque designs mount the body on a separate frame. These two designs each have their own characteristics and are suitable for different types of vehicles and applications.
[0003] Unibody construction offers relatively light weight, high space utilization, and good handling, but it also has high manufacturing and maintenance costs, poor off-road performance, lower rigidity, and a higher degree of customization. Body-on-frame construction, on the other hand, is robust and durable, easy to maintain, and has strong off-road performance, but it is heavier, less economical, and has lower space utilization.
[0004] Therefore, there is an urgent need for a load-bearing body with high rigidity, relatively light weight, high space utilization, and easy maintenance. Utility Model Content
[0005] This application provides an all-terrain chassis monocoque body. Based on the working conditions of lightweight mobile chassis, a monocoque body with high space utilization and relatively light weight is selected.

[0012] The four flanges of the vehicle body and the rivet nuts of the central reinforcing rib plate together fix the load-bearing cover plate to the vehicle body.
[0013] The side panels of the vehicle body are also welded with side ribs to support the force distributed by the load-bearing cover to the surrounding flanges of the vehicle body.
[0014] Sensor holes are also provided around the body of the vehicle.
[0015] Optionally, the steering wheel module has four flanges, which are welded into holes formed by the combination of a base plate and a reinforcing thin plate.
[0016] Preferably, to ensure that the four steering wheel module flanges are on the same horizontal plane to guarantee the motion accuracy of the chassis, the mounting surface of the steering wheel flange module is milled as a whole after welding.
[0017] Optionally, the charging pad bracket adopts a split design, with one part being a bracket for connecting the contact charging pad and the other part being a flange for connecting the vehicle body. The two parts are fixedly connected by bolts. This reduces costs and manufacturing difficulty.
[0018] Optionally, both the battery compartment and the battery compartment cover are made of sheet metal bent into shape.
[0019] Optionally, the vehicle body is also equipped with sensors and other components that are located inside the vehicle body;
[0020] The sensors and other components include: main radar, indicator lights, charging interface, speaker, expansion interface, emergency stop switch, antenna, camera, and ultrasonic radar;
[0021] The main radar and camera are fixedly connected to the vehicle body through an integrated frame. The main radar bracket can be moved back and forth through the waist hole so that the camera can be embedded in the front hole.
[0022] The indicator lights, emergency stop switch, and antenna are all rigidly connected to the four corners of the side plate by bolts.
