Description
Technical field
The utility model is related to a kind of onboard fans, refer in particular to the head oscillating structure of fan.
Background technology
The head-shaking device of onboard fan generally comprises head-shaking motor, crank and connecting rod, head-shaking motor drive crank and
Connecting rod drives fan head to swing；Due to automobile cab narrow space, fan head is easy to be obstructed or artificially push by force
Fan head turns to, and the drive shaft for all be easy to causeing head-shaking motor in this way twists off or transmission gear damage, influences the normal of fan
It works and shortens the working life.
Utility model content
In view of this, the utility model provides a kind of onboard fan head oscillating structure, plays protection motor, promotes fan operation
The effect of stability.
In order to achieve the above object, the technical solution of the utility model is：A kind of onboard fan head oscillating structure, includes fixation
Seat, rotating seat and driving rotating seat are relatively fixed the tumbler of seat rotation, and the tumbler includes head-shaking motor, song
Handle, crank set and connecting rod, head-shaking motor are mounted on rotating seat, and one end of crank passes through the driving of crank set and head-shaking motor
Axis connection, the other end connect composition linkage with the connecting rod for being articulated in fixed seat, and the crank set is fixed on the driving of head-shaking motor
On axis, which puts on one tank of forming, the inner wall of the tank circumferentially several arc grooves of ring cloth；The crank is in correspondence
The position that crank covers arc groove is equipped with steel ball and spring, and it is recessed which holds the arc covered in crank under the action of the spring
On slot.
The crank is pivotally connected with crank set, which puts on equipped with a connecting shaft, and crank is equipped with to be coordinated with the connecting shaft
Axis hole.
The crank is equipped with the slot of accommodating steel ball and spring.
The other end of the crank is equipped with the spindle being pivotally connected with connecting rod.
Steel ball and spring on the crank are symmetrical arranged using two groups.
Using the above structure, when the rotation of the utility model fan head is obstructed arc is covered with crank using the steel ball and spring of crank
Connected in star coordinates, and head-shaking motor is made to dally, and plays the effect of protecting motor, effectively promotes the stability of fan operation and uses the longevity
Life.

Fig. 5 is the assembled sectional view of Fig. 4.
Specific implementation mode
It elaborates to the utility model below in conjunction with attached drawing and specific implementation.
As shown in Figures 1 to 5, the utility model onboard fan head oscillating structure, include fixed seat 1, rotating seat 2 and
Driving rotating seat 2 be relatively fixed seat 1 rotation tumbler 3, the tumbler 3 mainly include head-shaking motor 31, crank 32,
Crank set 33 and connecting rod 34, head-shaking motor 31 are mounted on rotating seat 2, and power, one end of crank 32 are provided for tumbler 3
It is connect with the drive shaft 311 of head-shaking motor 31 by crank set 33, the other end connect group with the connecting rod 34 being articulated in fixed seat 1
At linkage.The crank set 33 is fixedly mounted in the drive shaft 311 of head-shaking motor, and crank set 33 is equipped with a tank 331,
Center is arranged a connecting shaft 332, the inner wall of the tank 331 circumferentially several arc grooves 333 of ring cloth；The crank 32
One end be articulated in crank set connecting shaft 332 on, the crank 32 be equipped with crank set connecting shaft 332 coordinate axis hole 321,
Specifically the crank 32 is covered in corresponding crank is equipped with steel ball 322 and spring 323, the crank 32 on the position of arc groove 333
It is equipped with the slot 324 of accommodating steel ball 322 and spring 323, steel ball 322 partly protrudes the top of slot 324 under the action of spring 323
It holds on the arc groove 333 that crank covers 331 inner wall of tank, plays positioning；The other end of the crank 32 be equipped with
The spindle 325 that connecting rod 34 is pivotally connected.
To ensure that the stabilization of crank 32 and 33 cooperation of crank set, the steel ball 322 and spring 323 are symmetrical arranged using two groups.
Above structure, when fan runs well, 31 drive shaft 311 of head-shaking motor drives 33 rotation of crank set, due to crank
32 steel ball 322 is held under the action of spring 323 on the arc groove 333 that crank covers 331 inner wall of tank, and head-shaking motor drives
The power of moving axis 311 is transmitted to by steel ball 322 and spring 323 on crank 32, so that crank 32 is rotated and is driven connecting rod 34, is driven
Rotating seat 2 is relatively fixed the rotation of seat 1, and fan head normally swings work；When external force blocks the swing of fan head, electricity of shaking the head at this time
Machine 31 keeps normal work, drive shaft 311 to drive crank set 33 that the resistance between steel ball 322 and spring 323 is overcome to be rotated further,
Idle running is formed, crank 32 and connecting rod 34 remain stationary as at this time, i.e., rotating seat 2 is motionless, can play protection head-shaking motor 31 in this way,
The effect for avoiding drive shaft 311 from twisting off.
The above, the only preferred embodiment of the utility model are not used for limiting the utility model implementation
Range.Therefore any changes or modifications made in the claims and specifications of the utility model, it should all belong to the utility model
Within the scope of patent covers.
