More specifically, the end face is located at one end of the first cylinder 210A away from the upper casing 200. The groove 211 is recessed on the end surface, and the positioning protrusion 311 is inserted therein. On the other hand, the end surface of the first cylinder 210A directly abuts against the surface of the curved hole 430 of the bending lug 420. The chance of the positioning projection 311 being disengaged from the groove 211 of the first cylinder 210A and the bending lug 420 of the carrier 400 can be reduced.

In this embodiment, the groove 211 and the positioning protrusion 311 are not limited to each other, as long as the positioning protrusion 311 can be accommodated in the restriction groove 211.

However, if the limiting groove 211 is further matched with the positioning protrusion 311, the positioning protrusion 311 and the groove 211 may have a cylindrical shape, a dome shape, a triangular column shape or a star shape. . However, the invention is not limited to this.

Thus, the recess 211 of the first cylinder 210A can just cover the positioning protrusion 311 by the positioning protrusion 311 being complementarily fitted to the groove 211 of the first cylinder 210A, so as to reduce the positioning bump 311 due to shaking. The opportunity to detach from the groove 211 of the first cylinder 210A and the bending lug 420 of the carrier 400.

In another embodiment, please refer to Figure 5. Figure 5 is a cross-sectional view showing another embodiment of the notebook computer 100' according to the present invention.

The first cylinder 210B is in the form of a sheet, such as a rib, and has an end surface that does not have a groove 211 and abuts against the surface of one of the bent holes 430 of the bent lug 420. In this way, since the first cylinder 210B is in the form of a sheet, it does not occupy too much space of the upper casing 200, so that a small arrangement space of the upper casing 200 can be saved to remove more use space.

In summary, the assembly structure of the notebook computer of the present invention can not only reduce the original design of the carrier without changing the internal device, but also reduce or even completely eliminate the use of bolts to fix the internal device on the casing, thereby reducing the use of bolts. At the cost of the cost, the steps to simplify the assembly of the notebook can be achieved.
