As long as you think that a person skilled in the art can understand your technical content based on the attached drawings, then assembly drawings, parts drawings, and structural drawings are all acceptable (if you think that the text of the instruction manual alone can If you can explain it completely clearly, you don’t even need to submit drawings, of course this is an extreme situation).
Note: As long as it can help explain the technical content, don't make a bunch of irrelevant and complicated diagrams. Of course, you must also pay attention to the sense of proportion, because you must know that if you want to add drawings in the subsequent procedures, it is generally very, very difficult (unless it is a drawing of background technology).
For specific instructions and drawing requirements, you can refer to the documents provided on the website of the State Intellectual Property Office, which is very detailed.
