Embodiment
Embodiment
The preferred embodiment of fan base 1 of the present utility model is as shown in Figure 3, and it comprises a fan base 10, and these fan base 10 inner containing spaces 120 that form for installing one fan blade and motor (not mark), and by revolution, drive blade performance heat radiation function; This fan base 10 is to connect with an assembling surface 100 to put on the engaging surface 106 of a casing of electronic apparatus 105, and four angle edge on this assembling surface 100 are to be formed with respectively and fan base 10 integrated engagement portions, comprise first engagement portion 101 that is positioned at these fan base 10 upper corners edge and second engagement portion 102 that is positioned at relative following end corner brim, wherein, this first engagement portion 101 is one and protrudes in this assembling surface 100, and assemble surperficial 100 vertical engagement portions, groove type plane 101 with this, 102 of this second engagement portions are to protrude in this assembling surface 100, and be formed at the hook type engagement portion 102 on this assembling surface 100, it is respectively the moulding with the edge plate stamping bending of this fan base 10.
In addition, this fan base 1 comprises that in addition one is installed with the snap-on spare 103 in this containing space 120, one-body molded with the plastic materials of these fan base 10 casings, the one end is to be fixed on the inserting and putting in the groove 104a of this fan base 10 sides, and its on-fixed end is a vertical bending shape, to form a pressure surface 103b, simultaneously, be formed with a buckling part 103a who protrudes in this assembling surface 100 on this snap-on spare 103 in addition, except that the buckling part 103a that exposes outside this assembling surface 100, this snap-on spare 100 all ranks in this containing space 120; Simultaneously, when this pressure surface 103b pressurized, this snap-on spare 100 will be a fulcrum with its fixed end, in this containing space 120, swing towards direction away from this engaging surface 106, and after pressure obtains discharging,, and make this buckling part 103a expose once more and protrude in outside this assembling surperficial 100 to the origin-location by the spring return of this snap-on spare 100; Wherein, the end face both sides of this fan base 10 can be offered an opening slot 104 respectively, borrow the position of this opening slot 104 in this containing space 120, to define the swing space of this snap-on spare 103, and make the user directly push this pressure surface 103b so that this snap-on spare 103 is exerted pressure by this opening slot 104.
This fan base 10 can be assembled in one for example on the casing 105 of electronic equipment such as computer main by this fan base 1, this casing 105 is as shown in Figure 4, has an engaging surface 106, this fan base 10 can be connect and put on it, and with its assembling surface 100 in abutting connection with this engaging surface 106, it on this engaging surface 106 the corresponding card complex hole that offers with respect to this engagement portion, comprise the first card complex hole 105a and the second card complex hole 105b that correspond respectively to this first engagement portion 101 and second engagement portion 102, the open surfaces of this first card complex hole 105a is slightly perpendicular to this engaging surface 106, plug for this first engagement portion 101, fixing, this second card complex hole 105b is opened on this engaging surface 106, buckles on it for this second engagement portion 105b; In addition, on the engaging surface 106 of this casing 105, with respect to the position of the buckling part 103a of this snap-on spare 103, other offers a fastening hole 105c, its size just can protrude in the buckling part 103a of the snap-on body on assembling surface 100 by ccontaining this, can be in it be fastened on, and this fan base 10 is fixed on this casing 106.
Therefore, when the user will be when this fan base 1 be assembled in this fan base 10 on this casing 105, can be earlier first engagement portion 101 of this fan base 10 be hooked in the first card complex hole 105a of this casing engaging surface 106, make this fan base 10 be positioned on the assembling position of this casing 105, then, the user can insert second engagement portion 102 of this fan base 10 in the second card complex hole 105b on these engaging surfaces 106 along its position, and four angle edge locating buttons on the assembling surface 100 of this fan base 10 are connected on this assembling position; At this moment, this fan base 10 is just finished its location snapping, but does not engage securely as yet, and it may drop under pressure or handling process.Therefore, the snap-on spare 103 of recycling fan base of user 1 design, press on this snap-on spare pressurized plane 103b by above-mentioned opening slot 104 positions, this direction of exerting pressure is the direction that cooperates this pressurized plane 103b, make it in this containing space 120, swing towards direction away from this composition plane 106, and the swing after borrowing this to exert pressure, make this snap-on spare 103 have an elastic force, this moment, this protruded in the buckling part 103a outside the assembling surface 100 originally, and the back pendulum is entered in this containing space 120; Therefore, when the pressure that is applied on this snap-on spare 103 obtains discharging, this snap-on spare 103 can be because of its elastic force, return to the not preceding position of pressurized of script, and make this buckling part 103a recover to protrude in the assembling surface 100 of this fan base 10, by its first engagement portion 101 and second engagement portion 102 be positioned at the engaging surface 106 of this casing 105 on owing to this fan base 10 this moment, so this buckling part 103a that returns to the origin-location can buckle the fastening hole 105c at relative position place on this engaging surface 106, and firmly fixing this fan base 10 whereby, it is exactly by this two first engagement portion 101, second engagement portion 102 is finished fixing with five point locations of the buckling part 103a of snap-on spare 103.
Above-mentioned assembly process operation is very easy and laborsaving, the while accurate positioning, deviation can not take place, this only needs can finish by the location action of simple engaging and fastening, more convenient than prior art, save trouble, and its integrated design also can not cause the loss of parts such as screw, also can not make this engagement portion or buckling part burst apart because of material engages with stress is concentrated; In addition, in the time of carrying out the dismounting of this fan base 10, only need to get final product by this fan base 1 reverse operating, have easy equally and the labour-saving effect according to identical step.
Fig. 5 shows the schematic representation after this fan base 10 is assembled in this casing 105, and it is the back side from Fig. 4, just the schematic representation looked of the opposing side of the engaging surface 106 of this casing 105.As seen from Figure 5, the buckling part 103a of this first engagement portion 101, second engagement portion 102 and snap-on spare 103 locatees the situation of this fan base 10 on this engaging surface 106.
Shown in Figure 6 is that the utility model will be at the quantity schematic representation of the increase fan base 10 on the same casing 105.Can on the engaging surface 106 of this casing 105, offer many group card complex holes and fastening hole, look user demand a plurality of fan bases 10 are installed on.Wherein, each fan base unit 10 all is the buckling parts with the first designed engagement portion, second engagement portion and snap-on spare, and is adjacent and connect and be positioned on the precalculated position, and all can bring into play dismounting and be easy to effect; Simultaneously, because it is minimum that this collocation method can make the span of each adjacent fans seat 10 reduce to, and the side of each fan base 10 is a plane, can fully reduce this space of fan base 10 in computer main or casing of electronic apparatus, also can be according to what of the inner heat that produces of this casing, look the fan base quantity that the demand adjustment is installed, make the increase and decrease of its assembling, dismounting and quantity have more simplicity and elasticity in casing inside.
In sum, fan base of the present utility model has the effect of quick and simple easy assembly and deassembly really, because it is one-body molded design, and does not use screw, reduces assembly cost and number of spare parts, also can reduce the space that takies in the casing simultaneously.
