Description

Radiator fan and notebook computer thereof

Technical field

This utility model relates to a kind of radiator fan for notebook computer, particularly relates to radiator fan and the notebook computer thereof of the anti-weight of a kind of energy.

Background technology

Nowadays the lightening design of electronic product is more and more general, especially in notebook computer product, which results in each parts in notebook computer and is intended to be adapted to the lightening design of notebook computer, just so, the inner space narrow and small in order to adapt to frivolous notebook computer, the spatial margin between each parts of radiator fan is caused to diminish, and the spatial margin between radiator fan and notebook computer casing or other parts diminishes, it is well known that, in prior art, the one end that radiator fan general structure is (referring to Fig. 5) central shaft for notebook computer arranges flabellum body 21, and flabellum body 21 be arranged above air inlet 11, its other end and stator module pivot joint, certain deformation can be produced when the shell of notebook computer is subject to the pressure from outside, the flabellum of radiator fan will be made to be squeezed when deformation quantity arrives after to a certain degree, thus have impact on the normal operation of radiator fan.

In prior art, in order to reach better radiating effect, generally the air inlet 11 of radiator fan arranges down and leaves certain interval with the base plate of notebook computer, but, in order to solve the extruded problem of radiator fan, the attitude of radiator fan is generally turned upside down by prior art, namely air inlet 11 is upward, but this mounting means, influences whether the intake at air inlet 11 place, thus reduce the radiating effect of radiator fan.

As preferably, described support member is tubular structure, and described bearing is located on the inwall of described support member to form pivot joint with described central shaft.

As preferably, the upper surface of described support member is provided with rubber blanket.

As preferably, described central shaft being arranged with two spacing back-up rings, and is laid in the two ends up and down of described bearing respectively.

As preferably, the upper surface of described housing has air inlet, and described support member protrudes the upper surface of described housing by described air inlet.

As preferably, described stator module has positioning sleeve, the lower end of described central shaft and described positioning sleeve pivot joint, and the induction coil of described stator module is laid in the periphery of described positioning sleeve.

As preferably, the central part of described fan is downward opening tubular structure, and a ringshaped magnet matched with described induction coil is fixed on the inwall of described tubular structure.

A kind of notebook computer, including as above any one described radiator fan.

Compared with prior art, the beneficial effects of the utility model are in that: its central shaft is protruded from radiator fan by the radiator fan that this utility model provides, and it is provided with the support member of the anti-weight of energy, support member is in order to keep out the pressure produced from the deformation of notebook computer casing, and, support member and central shaft adopt bearing fit to install, thus avoiding the harmful effect owing to the normal operation of radiator fan is brought by the deformation of notebook computer casing.

Detailed description of the invention

For making those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, this utility model is elaborated.

As it is shown in figure 1, a kind of radiator fan that this utility model provides, being applied on notebook computer, including housing 1, stator module and rotor assembly, in conjunction with corresponding accompanying drawing, those skilled in the art easily learn, also include air inlet 11 and air outlet 6. In the present embodiment, rotor assembly includes the central shaft 22 of flabellum body 21 and lower end and stator module pivot joint; The upper end of central shaft 22 is articulated with a support member 4 by bearing 7, to bear outside that central shaft 22 is axial pressure; Due to radiator fan of the prior art, when the shell at notebook computer is subject to the extruding generation deformation in the external world, the normal operation understood the direct or indirect flabellum body 21 touching radiator fan and have influence on radiator fan; So, this utility model provides a kind of radiator fan, is additionally arranged support member 4, when the shell of notebook computer is subject to extraneous compressional deformation, owing to the stop of support member 4 prevents computer casing from touching flabellum body 21, thus ensure that the normal operation of radiator fan.

As shown in Figure 4, the induction coil 32 of stator module is laid in the periphery of positioning sleeve 31, the central part of fan is downward opening tubular structure, one ringshaped magnet 23 matched with induction coil 32 is fixed on the inwall of tubular structure, under the interaction of induction coil 32 and ringshaped magnet 23, rotor assembly rotates around its central shaft 22.

Concrete, referring to Fig. 3 and Fig. 4, support member 4 is tubular structure, and bearing 7 is located on the inwall of support member 4 to form pivot joint with central shaft 22, and then ensure that when support member 4 is subject to notebook computer casing touching, will not hinder the normal rotation of central shaft 22, when the shell of notebook computer, under the effect of external pressure, sharply deformation occurs, for compensator or trimmer pressure, the upper surface of support member 4 is provided with rubber blanket 41, due in the embodiment that this utility model provides, certain interval is left between rubber blanket 41 and the shell of notebook computer on support member 4, in radiator fan work process, cause that support member 4 can rotate together with central shaft 22 owing to the bearing 7 between central shaft 22 with support member 4 exists minor rotation resistance, when the shell of notebook computer touches support member 4, owing to the effect support member 4 of inertia force will not stop operating immediately, and relatively rotate generation abnormal sound between support member 4 and notebook computer casing rubbing surface, thus reducing Consumer's Experience, set up rubber blanket 41 and too increase the frictional force between support member 4 and notebook computer casing while playing cushioning effect, can effectively stop being rotated further of support member 4, and then avoid the generation of abnormal sound. when support member 4 is subject to from the bigger pressure of the shell of notebook computer, slides axially along rotating axle for limiting bearing 7 further, central shaft 22 is arranged with two spacing back-up rings 5, and is laid in the two ends up and down of bearing 7 respectively.

When actually used, the position deformed upon due to the shell of notebook computer not can determine that, support member 4 protrudes the upper surface of housing 1 by the air inlet 11 on housing 1, to prevent the deformation of notebook computer casing from making the housing 1 of radiator fan be squeezed, and then have influence on the normal rotation of flabellum body 21.

Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model, and protection domain of the present utility model is defined by the claims. This utility model in essence of the present utility model and protection domain, can be made various amendment or equivalent replacement by those skilled in the art, and this amendment or equivalent replacement also should be regarded as dropping in protection domain of the present utility model.
