Description
Technical field
The present invention relates to household appliance technical field, more particularly to base assembly and the fan with the base assembly.
Background technology
Fan generally comprises fan head assembly and the base assembly for supporting fan head assembly, in order to expand the air-supply model of fan
Enclose, being generally provided with fan can realize in the oscillating mechanism of automatic left and right oscillating function, conventional art, and oscillating mechanism is general
All in the fan head assembly of fan, this setup is taken to cause the build for fanning head assembly than larger, and product is outer
Shape aesthetic property is poor.
The problem of in order to solve above-mentioned conventional fan, prior art proposes the side in base assembly by oscillating mechanism
Case.Existing that oscillating mechanism is located in the fan in base assembly, the base shell of base assembly mainly includes chassis and support
Seat two parts, oscillating mechanism is arranged on support base and chassis is enclosed in the cavity to be formed, and support base rotates with chassis and is connected and props up
Support seat is used to be connected with fan head assembly.Wherein, the implementation that is rotatably assorted between support base and chassis is：In chassis outer ring peace
A circular slip ring is filled, several positioning beads are installed in support base, can so make support base and fan head assembly left on chassis
When the right side is shaken the head positioning bead withstands on slip ring and slided, it is achieved thereby that support base and chassis are rotatably assorted.Support base and chassis
Between axial limiting mode be：One steel shaft is set in the mounting bracket bottom of oscillating mechanism, one is increased in the bottom on chassis
The axle sleeve coordinated with steel shaft, and axial limit is carried out to the axle sleeve being enclosed in steel shaft by installing a jump ring in the bottom of steel shaft
Position.During specific installation, first chassis and axle sleeve are placed in steel shaft successively, then loading onto jump ring in the bottom of steel shaft again is limited
Position, so, passes through the position-limiting action of jump ring so that axle sleeve and will not be slipped with chassis from steel shaft.Existing this head-shaking machine
Structure is arranged on the fan in base assembly, and following weak point is still suffered from a particular application：
1) mounting means of this oscillating mechanism adds slip ring, positioning bead, axle sleeve, jump ring these tiny assemblings zero
Part, so, on the one hand because assembling amount of parts is too many, therefore its mounting process is complicated, has had a strong impact on fan production effect
The raising of rate；And the accumulation of each parts foozle, the complication of fan mounting process can be further resulted in, while easily leading
Fan is caused to occur shaking the head when shaking the head operation the phenomenon of unstable interim card of shaking the head.
2) connection on support base and chassis installed in the jump ring in support steel shaft of shaking the head only by being locked, due to steel shaft
Diameter dimension is limited, and support base can be rotated relative to chassis, so causing other neighboring areas beyond jump ring fixation not have
There is any locking connection, along with the gap between each parts mutually moved so that support base and the peripheral clearance on chassis
It is uneven, so as to cause fan that abnormal sound of shaking the head occurs when shaking the head, while so that positioning bead is easily from support base and bottom
Disk in larger gap than dropping out, so as to have a strong impact on product reliability of operation.
3) in this existing scheme, chassis is on the ground, and support base is with respect to chassis or so yaw motion, and power line is peace
On the side wall on chassis, be then attached on the automatically controlled electrical part above support base, so, during shaking the head, chassis with
The power line connected between support base can constantly be swung, and easily make the power line fatigue break of inside.

Embodiment one：
As shown in figures 1 to 6, the base assembly 100 that the embodiment of the present invention one is provided, including base shell 1 and outside base
The oscillating mechanism 2 waved for driving fan head assembly 200 in shell 1, base shell 1 include fixed underpan part 11 and with fixation
Chassis portion 11, which rotates to connect, is simultaneously used for the rotation disc portion 12 for connecting fan head assembly 200, and fixed underpan part 11 is provided with the
One leads rotation structure and the first back-off structure, rotates disc portion 12 and is provided with lead that rotation structure is rotatably assorted with first second and leads and turns knot
Structure and the second back-off structure that coordinates with the first back-off structure back-off and can be slided with the first back-off structure opposing arcuate.
Specifically, fixed underpan part 11 can be positioned on ground or on table top or be installed on wall, rotation dish
Part 12 can drive fan head assembly 200 to be relatively fixed chassis portion 11 under the driving of oscillating mechanism 2 and carry out yaw motion.The
One back-off structure is rotatably assorted with the second back-off structure, refers specifically to：First, which leads rotation structure and second, leads rotation structure assembly connection
Relative rotary motion can be still carried out after together.In the present embodiment, first, which leads rotation structure and second, leads the cooperation of rotation structure, mainly
For limiting the relative radial motion between rotation disc portion 12 and fixed underpan part 11；First back-off structure and the second back-off
The cooperation of structure, on the one hand can limit the relative axial movement rotated between disc portion 12 and fixed underpan part 11；Separately
On the one hand it may also function as the work that limitation to a certain extent rotates relative radial motion between disc portion 12 and fixed underpan part 11
With, so, by first lead rotation structure with second lead rotation structure coordinate, the first back-off structure and being total to that the second back-off structure coordinates
Same-action, may be such that and the relative motion that rotates in a circumferential direction only is carried out between rotation disc portion 12 and fixed underpan part 11.This implementation
Being rotatably assorted and locking for the base assembly 100 that example is provided, fixed underpan part 11 and rotation disc portion 12 coordinates all directly logical
The respective outer side edges crossed fixed underpan part 11 and rotated on disc portion 12 are realized, without the other tiny assemblings of additional designs
Parts, so, on the one hand effectively reduce the amount of parts that base assembly 100 needs to assemble, so as to simplify base group
The mounting process of part 100, beneficial to improve fan production efficiency, and avoid due to assembling amount of parts it is excessive, each zero
The accumulation of part foozle causes fan to occur unstable, interim card of shaking the head phenomenon generation of shaking the head when shaking the head operation；On the other hand
It realizes locking positioning by the back-off of the first back-off structure and the second back-off structure, and its convenient disassembly, fastening are reliable, and due to
First back-off structure and the second back-off structure can opposing arcuate slide, therefore the back-off of the first back-off structure and the second back-off structure is matched somebody with somebody
Close not interfering with and rotate disc portion 12 and the relative rotary motion of fixed underpan part 11, and the first back-off structure and the second back-off
Structure is not in dropout phenomenon during the shaking the head of fan, and has fully ensured that the reliability of fan operation.
