Expansion structure of pivot assembly and application pivot assembly

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a pivot assembly, and more particularly to a pivot assembly having a rotational resistance that is different from the reverse rotational resistance and an expansion structure of the application pivot assembly.

The central processing unit (CPU) of the mainframe uses a random access memory (RAM) as a data storage area. The calculation results and program instructions of the central processing unit are placed in the random access memory. When the program needs to be executed, the data in the storage area can be accessed.

However, the functions of computer mainframes are becoming more and more powerful, and the demand for data processing speed and data volume is relatively increased. Therefore, users often want to increase the number of memory slots to expand the capacity of the memory. At present, the industry is to insert a memory expansion structure with a plurality of memory expansion slots on the memory slot of the motherboard to expand the memory of the computer mainframe. In order to increase the number of memory expansion slots, designers will increase the density of memory expansion slots. The memory expansion structure generally includes a dual expansion substrate And double pivoting components. The dual expansion substrate can be relatively closed or unfolded through the dual pivot assembly. When the memory expansion structure is expanded or closed, the memory located on the opposite expansion substrate is more likely to interfere with each other due to the dense arrangement of the memory. As a result, it will cause inconvenience to the assembler.

The invention provides an expansion structure of a pivot assembly and an application pivot assembly, thereby improving the memory of the expansion substrate when the memory expansion structure is unfolded or closed, and the memory of the relative expansion substrate is more likely to interfere with each other due to the dense arrangement of the memory.

The expansion structure disclosed in the present invention comprises a first expansion component, a second expansion component and a pivot component. The pivoting assembly includes a first pivoting member, a second pivoting member and a third pivoting member. The first pivoting member is coupled to the first expansion assembly. The second pivoting member is coupled to the second expansion assembly. The first pivoting member and the second pivoting member each have a shaft hole and a plurality of recesses on an inner wall surface of the shaft hole. Each recess has a first surface and a second surface opposite to each other. The angle between each of the first faces and the inner wall faces is different from the angle between each of the second faces and the inner wall faces. The opposite sides of the third pivoting member respectively comprise a shaft portion and a convex portion on the shaft portion. The two shaft portions are respectively pivoted on the two shaft holes, and the two convex portions are respectively located in one of the concave portions of the first pivoting portion and one of the concave portions of the second pivoting portion.

The pivot assembly disclosed in the present invention comprises a fourth pivoting member and a fifth pivoting member. The fourth pivoting member includes a shaft portion and a convex portion. The shaft portion has an outer wall surface. The convex portion is provided on the outer wall surface. The fifth pivoting member has a shaft hole and is located A plurality of recesses forming an inner wall surface of one of the shaft holes. Each of the recesses has a first side and a second side. The first surface and the second surface are staggered in a direction of rotation in which the central axis of the shaft hole is an axis of rotation, and the angle between each of the first surface and the inner wall surface is different from each of the second surface and the inner surface. The angle between the walls. The shaft holes are respectively pivoted to the shaft holes, and the convex portions are engaged with one of the concave portions.

According to the pivot structure of the present invention and the expansion structure of the application pivot assembly, the first angle and the second angle are both less than 90 degrees, and the first angle is different from the second angle. Therefore, when the two shaft portions pivot relative to the shaft hole, the rotation resistance in the clockwise rotation direction is different from the counterclockwise rotation resistance, so that the pivot speeds of the first expansion unit and the second expansion unit are inconsistent to avoid insertion in the pivotal speed of the second expansion unit. The memory of the first expansion component interferes with the memory inserted in the second expansion component.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the invention, and to provide a further explanation of the scope of the invention.
