The subject matter herein generally relates to adjusting modules for adjusting airflow through electronic devices.
A personal computer or server generates a lot of heat during operation. A fan is usually used to dissipate the heat, and an adjusting module is provided to adjust air to flow through the fan.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.
Several definitions that apply throughout this disclosure will now be presented. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.
The adjusting module 200 can comprise a motor 20 secured in the housing 110, a blade 10 configured to be rotated by the motor 20, and a reset component 30. The reset component 30 is configured to set the blade in a first position when the motor is not working.
The motor 20 can comprise a shaft 201. The shaft 201 can be rotated by the motor 20.
The reset component 30 can comprise a body 301, a first pin 302, and a second pin 303.
In one embodiment, the body 301 is installed on the shaft 201, the first pin 302 is configured to be secured to the housing 110 and the second pin 303 is configured to be secured to the blade 10.
When the motor 20 is in working, the blade 10 is rotated by the motor 20 with the shaft 201. The reset component 30 is resiliently deformed. The first pin 302 and the second pin 303 can press against the housing 110 and the blade 10.
When the motor 20 is not working and the blade 10 is stopped in a second position (shown in
In one embodiment, when the blade 10 is in the first position, a maximum airflow can pass through the blade 10. The electronic device 100 therefore retains good efficiency for heat dissipation.
In one embodiment, the adjusting module 200 can further comprise a mounting plate 40. The motor 20 can be fixed on the mounting plate 40 by at least one or more locking members 50. The locking members 50 may be screws, rivets, and so on. The mounting plate 40 defines a first through hole 401, a second through hole 402, a third through hole 403, and a fourth through hole 404.
The blade 10 can defines a fifth through hole 101 and a sixth through hole 102. The first pin 302 of the reset component 30 is secured in the fourth through hole 404. The second pin 303 of the reset component 30 is secured in the sixth through hole 102.
The shaft 201 passes through the first through hole 401 and the fifth through hole 101. The two locking members 50 are locked in the second through hole 402 and the third through hole 403 to secure the motor 20 to the mounting plate 40.
The shaft 201 comprises a first shaft part 201a and a second shaft part 201b. A shape of the first shaft part 201a is different from a shape of the second shaft part 201b. A cross section of the first shaft part 201a is matched with the first through hole 401, and a cross section of the second shaft part 201b is matched with the fifth through hole 101.
In one embodiment, the shape of the first shaft part 201a can be cylindrical, and the shape of the second shaft part 201b can be cuboid. The first through hole 401 can be circular, and the fifth through hole 101 can be rectangular.
In one embodiment, the reset component 30 can be a torsion spring.
In one embodiment, the adjusting module 200 can comprise two or more blades 10, and the reset component 30 can comprise two or more torsion springs. When the motor 20 is not working, one or more torsion springs can rotate the blades 10 to the first position.
