An oscillating head driving mechanism, a fan oscillating mechanism and a fan

Abstract

An oscillating drive mechanism disclosed in an embodiment of the present invention includes: a telescopic drive rod and a support rod; a connecting transmission part used to connect with the tail gear box pull rod of the fan oscillating mechanism, and the telescopic driving rod and the support rod are connected to the connecting transmission part , so that when the telescopic drive rod telescopically moves, the connecting transmission part drives the tail gear box pull rod to move up and down. The oscillating drive mechanism provided by the present invention is applied to a fan with a tail gear box. A telescopic drive rod, a support rod and a connecting transmission part are added to the fan. Both the telescopic drive rod and the support rod are connected with the connecting transmission part. During the telescopic movement, the connecting transmission part drives the tail gear box pull rod to move up and down, so as to realize the fan shaking or stop shaking the head. The telescopic driving rod can be realized by electric drive or electromagnetic drive. Compared with the traditional four-bar linkage mechanism driven by a stepping motor, it avoids occupying too much space and reduces the cost. The invention also discloses a fan shaking mechanism and a fan.

Description

technical field [0001] The invention relates to the technical field of fans, and more specifically, to an oscillating drive mechanism, a fan oscillating mechanism and a fan. Background technique [0002] The mechanical fan head shaking mechanism in the prior art utilizes the structure of the tail gear box to realize the fan head shaking. When the pull rod of the tail gear box falls, the gears in the tail gear box are disconnected, and the fan stops shaking its head. However, the mechanical fan oscillating mechanism needs to manually push and pull the tail gear box lever to move, and cannot realize automatic control. [0003] In order to meet the requirements of automatic control, there is also an electronic fan oscillating mechanism in the prior art, and the electronic fan oscillating mechanism adopts a synchronous motor to turn on and off the power to realize the fan oscillating. When the synchronous motor is powered on, the synchronous motor is used to drive the four-bar...

Problems solved by technology

[0004] However, the cost of using the synchronous motor to turn on and off the fan head is high, and the synchronous motor takes up a lot of space. It is necessary to increase the fixing bracket of the synchronous motor. While increasing the materials, the assembly time and labor are relatively increased.

[0005] Therefore, how to avoid taking up too much space and reduce costs while satisfying automatic control has become a technical problem to be solved urgently by those skilled in the art.
