Description
Technical field
It the utility model is related 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 is used to support the base assembly of fan head assembly, in order to expand the air-supply model of fan
Enclose, be generally provided with the oscillating mechanism that can realize automatic left and right oscillating function on fan, in conventional art, oscillating mechanism is general
All in the fan head assembly of fan, take this setup that the build for fanning head assembly can be caused bigger, and product is outer
Shape aesthetics is poor.
In order to solve the problems, such as above-mentioned conventional fan, the prior art, which proposes, is arranged on oscillating mechanism the side in base assembly
Case.Existing that oscillating mechanism is arranged in the fan in base assembly, the base shell of base assembly mainly includes chassis and support
Seat two parts, in the cavity that support base and chassis are enclosed, support base is rotatablely connected and props up with chassis oscillating mechanism
Support seat is used to be connected with fan head assembly.Wherein, the implementation that is rotatably assorted between support base and chassis is：Pacify in chassis outer ring
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
Positioning bead withstands on slip ring and slides when the right side is shaken the head, 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, increases by one in the bottom on chassis
The axle sleeve coordinated with steel shaft, and axial limit is carried out to the axle sleeve being sleeved in steel shaft by installing a clamp spring in the bottom of steel shaft
Position.During specific installation, first chassis and axle sleeve are placed in steel shaft successively, then loading onto clamp spring in the bottom of steel shaft again is limited
Position, in this way, the position-limiting action for passing through clamp spring so that axle sleeve and will not be slipped with chassis from steel shaft.Existing this head-shaking machine
Structure is installed on the fan in base assembly, still suffers from following shortcoming in a particular application：

The raising of rate；And the accumulation of each parts foozle, the complication of fan mounting process can be further resulted in, while easily lead
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 clamp spring in stent 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 clamp spring 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 cause positioning bead easily from support base and bottom
Disk drops out in bigger gap, so as to seriously affect product reliability of operation.
3) in this existing scheme, chassis is put on the ground, and support base is with respect to chassis or so yaw motion, and power cord is peace
On the side wall on chassis, be then attached on the automatically controlled electrical part above support base, in this way, during shaking the head, chassis with
The power cord connected between support base can constantly be swung, and easily make the power cord fatigue break of inside.

Embodiment one：
As shown in figures 1 to 6, the base assembly 100 that the utility model embodiment one provides, including the base shell 1 and bottom of arranged on
For the oscillating mechanism 2 that waves of driving fan head assembly 200 in seat shell 1, base shell 1 include fixed underpan part 11 and with
Fixed underpan part 11 is rotatablely connected and the rotation disc portion 12 of head assembly 200 is fanned for connecting, and is set on fixed underpan part 11
There is first to lead rotation structure and the first back-off structure, rotate disc portion 12 and be equipped with lead that rotation structure is rotatably assorted with first second and lead
Rotation structure and the second back-off structure that coordinates with the back-off of the first back-off structure and can be slided with the first back-off structure opposing arcuate.
Specifically, fixed underpan part 11 can be positioned on ground and either on table top or be installed on wall, rotating disc
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 rotated between 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 between limitation rotation 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 in this way, being led by first, rotation structure leads rotation structure cooperation with second, the first back-off structure is total to what the second back-off structure coordinated
Same-action, may be such that and rotate the only opposite movement that rotates in a circumferential direction of progress between disc portion 12 and fixed underpan part 11.This implementation
Example provide base assembly 100, fixed underpan part 11 and rotate disc portion 12 be rotatably assorted and lock cooperation all directly lead to
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, in this way, the amount of parts that base assembly 100 needs to assemble on the one hand is effectively reduced, so as to simplify base group
The mounting process of part 100, beneficial to the production efficiency of raising fan, and avoids since assembling amount of parts is excessive, zero each
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, its is convenient for disassembly and assembly, fastening is 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.
Preferably, with reference to shown in Fig. 2-5, the first back-off structure is the first cam being convexly equipped on fixed underpan part 11
