Description

Technical Field

[0001] The present application relates to the technical field of notebook hinges, and in particular to a dustproof rotating support frame for a notebook computer. Background Art

[0002] The screen hinge structure is used to connect the display and keyboard of the notebook computer, and the display is hinged on the keyboard to realize the flipping of the display. There is a large gap between the existing rotating frame and the base of the notebook computer, which is easy to accumulate dust in the gap, and dust can easily enter the computer, affecting the normal operation of the computer.

[0003] In this regard, China's patent application number is CN202021171866.6, which discloses a rotating bracket for a laptop computer. This solution mainly arranges a layer of sealant between the sleeve and the mounting hole to achieve sealing.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] Since the sleeve needs to be inserted into the mounting hole, in order to prevent the sealant layer from being scraped off by the mounting hole, an appropriate gap must be left between the mounting hole and the sleeve. This results in an excessively large assembly gap, and the liquid elastomer sealant has a certain softness, which makes it impossible to achieve a stable connection between the sleeve and the mounting hole, resulting in a small amount of shaking between the screen and the base, and even a situation where they cannot be closed together, affecting the user experience.

In this embodiment, the inner sleeve and the expansion bars are integrally formed.

[0012] In a specific embodiment, the tensioning member includes a pull rod, the pull rod movably passes through the rotating shaft, and the inner end of the pull rod is rotatably connected to the expansion core.

[0013] In the above implementation process, the pull rod is used to pull the internal expansion core from the outside to move axially, and the pull rod does not rotate with the expansion core.

In this embodiment, six threaded through holes are provided, and seven pin holes are provided on the riveted part. In this way, each time the nut rotates a small angle, there is a threaded through hole corresponding to the pin hole, so that the nut is kept at a suitable torque.

Among them, the outer sleeve 41 and the inner sleeve 42 use the self-centering function of the conical surface connection to improve the assembly accuracy, improve the connection stability, and effectively reduce the shaking, and the tensioning member 60 is used to cooperate with the tensioning member 50 to achieve locking from the outside, so that the mounting hole 20 can be completely closed, and the dust is prevented from entering the computer from the gap of the shaft sleeve 40.

[0029] See also Figure 1-Figure 3 The outer end of the rotating shaft 30 is riveted to the support frame 10 to form a riveted portion 70. The outer end of the rotating shaft 30 is directly riveted to the support frame 10, and the connection strength is high.

[0030] See also Figure 1-Figure 4 The tensioning member 50 includes an expansion bar 51 and an expansion core 52. The expansion bars 51 are arranged in a circumferential array on the outer circle of the inner sleeve 42, and the expansion core 52 is located inside the expansion bars 51. All the expansion bars 51 are movably attached to the expansion core 52. When inserted, all the expansion bars 51 are attached to the expansion core 52 inwardly. When fixed, the expansion core 52 is pulled outward by the tensioning member 60, and the expansion core 52 pushes all the expansion bars 51 to expand outward and abut against the conical surface in the mounting hole 20, thereby achieving the fixation of the inner sleeve 42 and the mounting hole 20. In this embodiment, the inner sleeve 42 and the expansion bars 51 are integrally formed.

[0031] See also Figure 1-Figure 4 The tensioning member 60 includes a pull rod 61, which movably passes through the rotating shaft 30, and the inner end of the pull rod 61 is rotatably connected to the expansion core 52. The pull rod 61 is used to pull the internal expansion core 52 from the outside to move axially, and the pull rod 61 does not rotate with the expansion core 52.

The tensioning member 60 also includes a nut 62, which is threadedly connected to the outer end of the pull rod 61, and the nut 62 is tightened on the end surface of the riveted portion 70. The pull rod 61 is circumferentially fixed to the rotating shaft 30 by means of a hexagonal shape, and the nut 62 can be directly rotated and tightened, and the pull rod 61 is pulled outward by threading.

[0033] See also Figure 2-Figure 3, a threaded through hole is provided on the nut 62, a pin hole is provided on the end surface of the riveted part 70, and a top screw 63 is screwed into the threaded through hole and pinned to the pin hole.

In this embodiment, six threaded through holes are provided, and seven pin holes are provided on the riveted part 70. In this way, each time the nut 62 rotates a small angle, there is a threaded through hole corresponding to the pin hole, so that the nut 62 is kept under a suitable torque.

[0034] The working principle of the dustproof rotating support for laptop computers is as follows: when inserted, all expansion bars 51 are fitted inwardly onto the expansion core 52, and the rotating shaft 30 is inserted into the mounting hole 20 until the conical surface of the outer sleeve 41 is fitted onto the outer side of the mounting hole 20. At this time, the nut 62 is screwed to the outer end of the pull rod 61 and tightened. During the tightening process, the pull rod 61 is pulled outward, while carrying the expansion core 52 to move axially outward. The expansion core 52 pushes all expansion bars 51 to expand outward and rest against the conical surface in the mounting hole 20, thereby achieving the fixation of the inner sleeve 42 and the mounting hole 20, thereby fixing the entire bearing in the mounting hole 20. In summary, the outer sleeve 41 and the inner sleeve 42 use the self-centering function of the conical surface connection to improve the assembly accuracy, improve the connection stability, and effectively reduce the shaking, and use the tensioning piece 60 to cooperate with the tensioning piece 50 to achieve locking from the outside, so that the mounting hole 20 can be completely closed, thereby preventing dust from entering the computer from the gap in the shaft sleeve 40.
