Abstract
The utility model relates to a shock-absorbing unit structure, which is mainly characterized in that a shock-absorbing unit is arranged between the bearing support and the coil holder of the fan; the shaking because of the high speed rotating absorbing fan touching the bearing support is cushioned by the shock-absorbing unit, which reduces the over-noisy sound generated from the bearing support impacting the coil holder and also prevents the increasing offset of the fan from affecting the air speed.
Description
Technical field
The utility model relates to a kind of modified model fan shock-absorbing unit structure, particularly a kind of radiation fan that is configured on the electronic equipment.
Background technique
The fan 10 that is used for the contour arithmetic element of microprocessor at present, cause is along with arithmetic speed day by day improves, the rotating speed of fan 10 also improves thereupon, but, fan 10 improves because of rotating speed, cause the number of times of fan 10 rotating shafts 16 impact groove bearings 12 to increase relatively, rock when touching coil base 13 at axle bed, promptly can produce the noise of bump, and fan 10 can be offset more under excessively rocking because of flabellum 11, cause rotating shaft 16 to reduce its working life with bearing support 12 excessive wears, in addition, fan 10 more directly influences its rotating speed and air quantity thereof because of drift rate is excessive, and the more direct fan 10 available radiating efficiencys that allow greatly reduce.
For improving above-mentioned shortcoming, related domain is in order to reduce the problem of rocking of fan 10 at present, as shown in Figure 1, it is a sheathed shock-absorbing unit 18 in the rotating shaft 16 of fan 10, when bearing support 12 is put in rotating shaft 16, shock-absorbing unit 18 fills up residue bearing support 12 spaces immediately, and when magnet 111 on the fan 10 and coil base 13 produces power rotating shaft 16 rotated rapidly, directly draw shaking force by shock-absorbing unit 18, with the problem of avoiding fan 10 to rock, but, 16 of rotating shafts are as the purpose that reaches high speed rotating, and bearing support 12 must be reserved appropriate space for rotating shaft 16 assemblings, but since shock-absorbing unit 18 must fill up whole space and can reach shock-absorbing effect, limiting rotating shaft 16 so on the contrary rotates, and fan 10 available wind speed can't significantly be promoted, the microprocessor that corresponding arithmetic speed at present day by day raises can not satisfy use at all, even it is lubricated to be preset with petroleum province 15 in the bearing support 12, but the improvement meaning that can show and little; Moreover, 16 of rotating shafts are with end configuration shock-absorbing unit 18, this balance mode is inexcellent, in addition, the fan 10 actual noises that produce not are the collision that is rotating shaft 16 and bearing support 12, but be that coil base 13 and bearing support 12 are subjected to rotating shaft 16 interlocks and produce, but above-mentioned shock-absorbing unit 18 only can slightly reduce rotating shaft 16 and the wear problem that bearing support 12 excessively touches, and then can't improve fully for the actual noise problem that should solve.
Summary of the invention
Main purpose of the present utility model, be to solve the aforesaid drawbacks, avoid the existence of shortcoming, the utility model mainly disposes a shock-absorbing unit between the bearing support by fan and the coil base, provide a buffering to absorb the fan shaft high speed rotating by this shock-absorbing unit and touch rocking that bearing support produces, cause the problem of excessive noise in order to reduce bearing support bump coil base, and avoid the fan side-play amount to increase and influence its wind speed.
Relevant detailed description of the present utility model and technology contents, existing as follows with regard to accompanying drawings:
Description of drawings
Fig. 1 is existing fan cross-sectional view;
Fig. 2 is a cross-sectional view of the present utility model;
Fig. 3 is another an embodiment's of the present utility model cross-sectional view.
Embodiment
See also Fig. 2, it is cross-sectional view of the present utility model, as shown in the figure: the utility model is to dispose a shock-absorbing unit 14a, 14b between the bearing support 12 of fan 10 and coil base 13, absorb fan 10 rotating shafts 16 high speed rotating by this shock-absorbing unit 14a, 14b and touch rocking that bearing support 12 produced, cause the problem of excessive noise to reduce bearing support 12 bump coil bases 13, and avoid fan 10 side-play amounts to increase and influence its wind speed.
By can obviously finding out among the figure, when utilizing on it magnet 111, fan 10 flabellums 11 produce electromagnetism and when rotating in coil base 13 energisings, rotating shaft 16 is subjected to the aforementioned electromagnetic driving and rotates at bearing support 12, because it is lubricated that general axis bearing 12 is equipped with petroleum province 15, so rotating shaft 16 can be avoided over worn situation (aforementioned fan 10 drive manners are prior aries, below repeat no more) when bearing support 12 rotates.And the utility model mainly utilizes these bearing support 12 outer peripherys to be provided with one for shock-absorbing unit 14a, the annular groove 121 of 14b configuration, when rotating shaft 16 is rotated rapidly, being subjected to centrifugal force involves, must collide bearing support 12 generations rocks, at this moment, by shock-absorbing unit 14a, 14b spacing shaft bearing 12 and coil base 13, and this shock-absorbing unit 14a, 14b is rubber or other soft material, when bearing support 12 rocks, by shock-absorbing unit 14a, the buffer function of 14b, make the dynamics of rocking of bearing support 12 can be by shock-absorbing unit 14a, the 14b appropriateness absorbs, and bearing support 12 can not touch coil base 13 and noise problem can effectively avoid fan 10 to rotate the time, and fan 10 is at shock-absorbing unit 14a, when 14b slows down bearing support 12 shaking degree, rotating shaft 16 is kept to run well and maintenance fan 10, in addition, shock-absorbing of the present utility model unit 14a, 14b respectively disposes one with rotating shaft 16 two ends, the balance of whole fan 10 absorbing forces of impact degree can be provided, in order to the heat dissipation of fan 10 maximums to be provided, and effectively to the heat radiation purpose is provided by radiator.
See also Fig. 3, it is another embodiment's of the present utility model cross-sectional view, wherein, this shock-absorbing unit 17 is extensible an inner edge portion 171, make shock-absorbing unit 17 be set in bearing support 12 upper ends, and this inner edge portion 171 is not to fill up the remaining space of bearing support 12 fully, but leave a fixed gap and avoid influencing rotating shaft 16 and rotate, the main purpose of this inner edge portion 171 is that rotating shaft 16 produces when being offset than wide-angle because of improper excessively rocking, and inner edge portion 171 can provide rotating shaft 16 to revise in real time and absorb the dynamics that rotating shaft 16 is touched suddenly.
The above, it is preferred embodiment of the present utility model, can not be in order to limit the scope that the utility model is implemented, i.e. equivalent substitutions and modifications of being done according to the utility model claim generally all should still belong in the scope that the utility model contains.
