Fan and terminal device

Abstract

This application provides a fan, including a base, a bearing, and a rotating shaft. The base has a receiving cavity and a first bottom wall; the bearing is located in the receiving cavity; the rotating shaft is located in the receiving cavity and passes through the bearing, the rotating shaft being used to rotate relative to the bearing; wherein, the base further includes a protrusion extending from the first bottom wall toward the receiving cavity, the protrusion contacting an end of the rotating shaft. This application also provides a terminal device.

Claims

1. A fan, improved in that it includes: The base has a receiving cavity and a first bottom wall; The bearing is located in the receiving cavity; The base also includes a rotating shaft located within the receiving cavity and passing through the bearing, the rotating shaft being used to rotate relative to the bearing; wherein the base further includes a protrusion extending from the first bottom wall toward the receiving cavity, the protrusion contacting the end of the rotating shaft.

2. The fan as described in claim 1, wherein, The base includes a first bottom wall, a first side wall, a second bottom wall, and a second side wall, which together form the receiving cavity. The receiving cavity includes a first mounting groove and a second mounting groove, with the second mounting groove surrounding the first mounting groove. The first bottom wall and the first side wall form the first mounting groove, and the second bottom wall and the second side wall form the second mounting groove. The bearing is located in the second mounting groove, and the rotating shaft is located in the first mounting groove.

3. The fan as described in claim 2, wherein, The surface of the rotating shaft that contacts the first bottom wall is an arc surface.

4. The fan as described in claim 2, wherein, The surface of the rotating shaft that contacts the first bottom wall is a plane.

5. The fan as described in claim 1, wherein, The fan also includes a coil, a magnetic component, a magnet, and a housing. The magnetic component is fixed to the base. The coil is wound around the magnetic component. The rotating shaft and the magnet are both fixed to the housing. The magnet and the magnetic component are spaced apart. The magnetic component is located within the magnetic field range of the magnet, and the magnet is used to attract the magnetic component.

6. The fan as described in claim 5, wherein, The housing includes a body and an extension. The rotation axis is located at the center of the body and extends toward the base. The extension is located at the end of the body and extends toward the base relative to the body.

7. The fan as described in claim 6, wherein, The fan also includes fan blades, which are fixed to the housing.

8. An improvement of a fan, comprising: The base has a receiving cavity and a first bottom wall; The bearing is located in the receiving cavity; A rotating shaft is located in the receiving cavity and passes through the bearing, the rotating shaft being used to rotate relative to the bearing; wherein, the end of the rotating shaft includes a protrusion that protrudes toward the first bottom wall and contacts the first bottom wall.

9. The fan as described in claim 8, wherein, The first bottom wall is a plane.

10. A terminal device, improved in that the terminal device includes a fan as described in any one of claims 1 to 9.
