Specific embodiment
In order to be best understood from the purpose of the present invention, structure and function, 1-9 with reference to the accompanying drawing, the understanding of the present invention.
Using program setting and structure cooperation inside existing electric fan, it fan head may be implemented can control to shake the head, it is this to match
When the driven gear installation that conjunction left and right is shaken the head is fixed, the mode for mostly using pure screw fixed, it is inconvenient to assemble, and expends working hour；And nothing
Method realizes multi-purpose content.
And a kind of driven gear component that the present invention designs, innovative point of the present invention are: by designing a kind of driven tooth
Wheel assembly 3, so that the driven gear component 3 can both be connected with support tube 4, while can also be with fan head components
Electric machine support 5 connects, and realizes multi-purpose content；Driven gear component 3 and support tube 4 are fixed using buckle plus a screw, driven
Gear assembly 3 and electric machine support 5 are fixed using the linking of pure buckle, are arranged and fixed conveniently.
As shown in Figs 1-4, the line excessively including electric machine support 5,5 lower end of electric machine support for fan head assembly to be fixedly mounted
What pipe 501 relatively rotated is plugged in support tube 4, is equipped on electric machine support 5 for the electronic of driving fan head assembly swing
Machine 1, motor 1 output shaft be connected with driving gear 2；The interference fit of driving gear 2 is connected on the output shaft of motor 1
Face, driving gear 2 and the engagement of 3 tooth position of driven gear, the top of driven gear 3 are equipped with arc teeth；Driving gear 2 is nibbled around it
The driven gear component 3 of conjunction rotates, to realize that fan head assembly is swung around support tube 4；When motor 1 drives driving gear
2 rotations, since driven gear component 3 is in stationary state, at this point, driving gear 2 can be with driven gear component 3 for center pitch of the laps
Rotation, so that motor 1, fan head assembly, electric machine support 5 are together by the wire-passing tube 501 of lower end in support tube 4
Rotation, to realize the swing of fan head assembly.
It is stepper motor that above-mentioned motor 1, which can be selected, the power take-off mechanism shaken the head as complete machine or so；Walk motor
A support plate 6 is set below and is used to support stepper motor, and stepper motor and support plate 6 are fixed on together on electric machine support 5.Motor
The rotation of wire-passing tube 501 of 5 lower end of bracket is plugged in driven gear component 3 after vestibule, and 3 outer wall of driven gear component is fixed again to be inserted
It is connected in support tube 4.Conducting wire via hole effect of the wire-passing tube 501 for interspersed internal electric device.
Such as Fig. 3, driven gear component 3 is the cavity tubular structure that top has teeth, and driven gear component 3 passes through card
The mode of connecing is removably mounted in support tube 4.
The buckle limit offered such as Fig. 3,5,9, the buckle 301 and 4 side wall of support tube of 3 lateral wall of driven gear component connection
Position 402 Elastic buckle of hole connects and limits and freely up and down spend.It is preferred that the wedge cleaving type structure that buckle 301 is at least two, and buckle
It is symmetrical arranged between 301, realizes stress equalization, clamping is firm.
Advanced optimize design, 4 side wall of the first screw hole 302 and support tube that 3 lateral wall of driven gear component also opens up
It is connected by screw between the second screw hole 401 opened up and limits and freely up and down spend, so that limiting up and down more stable.In order to fixed
Position rotation direction freedom degree, the limit rib 304 and 4 sidewall upper edge of support tube that 3 upper side wall of driven gear component is additionally provided with are opened
If spacing breach 404 match, to limit the rotational freedom that driven gear component 3 detours on support tube 4.
Such as Fig. 3 and 4, the matching of positioning bar 305 that 3 lateral wall of driven gear component is also set up snaps onto 4 side wall of support tube and opens
If locating notch 403 in realize assembly positioning, by such positioning, the dislocation waited during installation can be prevented so that assembly
More precisely contraposition.
Further, the snap-on linking notch 502 and driven gear that 501 outer wall of wire-passing tube of 5 lower end of electric machine support opens up
The lateral wall of component 3 is connected with snap-on 303 and is fitted into, so that the freely up and down degree to driven gear component 3 limits.Snap-on 303
Inner sidewall is provided with protrusion, which snaps onto snap-on linking notch 502, so that the wire-passing tube 501 of 5 lower end of electric machine support
It freely up and down spends and is limited, can only realize rotation, to realize that the cooperation of fan is shaken the head.
Such as Fig. 1 and 2, the kind driven gear component that the present invention is designed is used in existing fan, and fan includes fan
Pedestal and fan head assembly, fan head assembly are driven by driving gear 2 and above-mentioned driven gear component cooperative movement realization
Movable pendulum head.
In specific implementation step:
Step 1: the connection of the interference fit of driving gear 2 or pin key are connected to above the output shaft of stepper motor 1；
Step 2: stepper motor 1 and support plate 6 are fixed on above electric machine support 5 by two screws；
Step 3: driven gear 3 by the spacing breach 403 above positioning bar 305 and support tube 4 match realization from
The assembly of moving gear 3 positions；Two buckles 301 above driven gear 3 and two buckle limit holes 402 above support tube 4
Match the limit up and down of driven gear 3；Screw hole 302 above driven gear 3 and the screw hole above support tube 401 are opposite
It answers, makes a call to moving forward and backward for the fixed limitation driven gear 3 of a screw；On limit rib 304 and support tube 4 above driven gear 3
Two spacing breach 404 in face match the left and right displacement of limitation driven gear 3；
Match step 4: electric machine support 5 is connected two snap-ons 303 above notch 502 and driven gear 3 by snap-on
It closes, forms the limit up and down to driven gear 3.
