Electronic cabin of an underwater robot with a stacked assembly structure

Abstract

The invention belongs to the field of underwater robots, in particular to an electronic cabin of an underwater robot suitable for a stacked assembly structure of a miniature underwater robot. The electronic cabin of the underwater robot with a stacked assembly structure is composed of three parts: the pressure-bearing shell assembly, the electronic fixing frame, and the electronic module assembly. The pressure-bearing shell is installed on the underwater robot and has a raised platform inside; Stainless steel screws, nuts, and spring washers are used to fix the circular bakelite board. The stainless steel screw protrudes outside the front panel and is used to fix the end surface with the inner protrusion of the pressure-bearing shell; multiple electronic modules are on the electronic fixing frame. The upper adopts a stacked assembly structure, and the normal direction of the module circuit board is parallel to the axial direction of the pressure-bearing shell. The propeller motor driver adopts a modular structure and is electrically connected in the form of a bus. Compact structure, high space utilization. There is little restriction on the height of the stack structure. Wiring is easy. Easy maintenance and replacement. Modular design, good interchangeability.

Description

technical field [0001] The invention belongs to the field of underwater robots, in particular to an electronic cabin of an underwater robot suitable for a stacked assembly structure of a miniature underwater robot. Background technique [0002] As an important detection system in the ocean, the micro underwater robot has the characteristics of small size, light weight, low noise and good concealment, and has played an important role in the maintenance of marine rights and interests and marine development. The underwater robot electronic cabin is an important part of the underwater robot. It is used to withstand the external seawater pressure and provide a dry airtight cabin to protect various electronic modules such as the main control unit, motor driver, and signal conversion board installed inside. Will fail or be damaged due to seawater pressure and seawater corrosion. Based on factors such as fluid movement resistance, internal space efficiency, manufacturing difficulty...

AI Technical Summary

Problems solved by technology

This installation method can realize the reliable fixation and connection of each electronic module inside the electronic cabin, but there are the following problems: the arc space around the partial stack cannot be effectively used, and the closer the width of the electronic module is to the inner diameter of the electronic cabin, the smaller the partial stack can be. The fewer electronic modules are installed, the local stack height is limited, and the space utilization rate is low, which will easily lead to insufficient installation space inside the electronic cabin (such as the attached figure 2 shown); the overall wiring inside the electronic cabin is difficult

Therefore, the above-mentioned patent can obtain good application effects on underwater robots with large diameter electronic cabins, but it is not applicable to micro-sized underwater robots.
