Description

Spreading fin structure

This creation is about a kind of spread-wing fan structure, especially a kind of so-called blade that can achieve the synchronous unfolding action, so as to reduce the occurrence of fault damage, and extend the service life thereof, and more practical effect in its overall implementation. Innovative designer of the characteristic wing-wing structure.

According to the recent changes in the environment, people are paying more and more attention. Due to the influence of the greenhouse effect, the global temperature is increasing year by year, and the impact on people's daily life is increasing with the increase of temperature, not only in summer. The temperature is often unbearable, and even in winter, the temperature is often as high as 27-28 degrees, and the buildings in which people live and work are generally hot and not ventilated. The state makes it easier for people to feel uncomfortable in such an environment. Therefore, all kinds of heat-dissipating and cooling products that make people feel cool and comfortable can be said to be one of the essential items in daily life. .

For the general purpose of the fan, please refer to M387920, "Synchronized Folding and Folding Structure of the Folding Fan" on September 1, 1999, which includes a driving device, a plurality of casings, a plurality of connecting rods and a plurality of links. The fan blade is composed of: the driving device is provided with a plurality of supporting frames, and the supporting frame is provided with a pivot column; the housing is provided with a pivot hole for pivoting the pivot column; the connecting rod is respectively pivoted at both ends The two adjacent housings; the fan blade is provided with a set of combined portions for the housing at one end thereof, and the combined portion is provided with a through hole for pivoting the pivot; accordingly, the housings are synchronized by the connecting rod The support frame pivots while the fan blade and the housing are in a synchronously unfolded or collapsed state.

However, the above-mentioned "synchronized unfolding and folding structure of the spreading fins" can achieve the intended effect of being unfolded when not in use, and is also used for its deployment, but it is also found in its actual implementation that the structure is driven by the driving device. The support frame rotates, so that each blade and the casing are pivoted relative to the support frame by centrifugal force, and the adjacent fan blades are driven synchronously through the connecting rod and the casing, so that the fan blades are synchronously unfolded or folded, resulting in long After the time is used, there will be a phenomenon of dust accumulation or rust between the connecting rod and the casing, which may result in the fact that the fan blades cannot be unfolded or folded synchronously, which may affect the service life of the fan. There is still room for improvement in the overall structural design.

The reason is that, in view of this, the creators have been researching and improving the existing structures and defects by providing rich experience in design and development and actual production of the relevant industries for many years, and to provide a structure for spreading wings and fins in order to achieve better practical value.

The main purpose of the present invention is to provide a propeller fan structure, which is mainly characterized in that the driving device uses the annular tooth portion to synchronously drive the rotation of the toothed discs of the respective blades, so that the blades can reach the synchronous unfolding action, so as to reduce the occurrence of fault damage. , with extended service life, and more practical performance characteristics in its overall implementation.

The main purpose and effect of the wing structure of this creation are achieved by the following specific technical means:

It mainly consists of a drive unit and several blades;

The driving device is provided with a rotating power source, and the rotating power source is connected to the rotating disk, and the rotating disk is provided with an annular tooth portion, and the rotating disk has a plurality of fans on the outer edge of the corresponding annular tooth portion. The blade is provided with a toothed disc between each of the blades and the rotating disc, and the fan blade is combined with the toothed disc, so that the toothed disc is pivotally mounted on the rotating disc, so that the toothed disc can rotate on the rotating disc, and The toothed disc is engaged with the annular tooth portion, and a reset elastic member is disposed on the toothed disc, and the other end of the return elastic member is fixed on the rotating disc.

In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings:

First, please refer to the schematic diagram of the three-dimensional exploded structure of the first figure. The creation mainly includes a driving device (1) and a plurality of blades (2); wherein:

The driving device (1) is provided with a rotating power source (11), and the rotating power source (11) is assembled with a rotating disk (12), and the rotating disk (12) is provided with an annular tooth portion ( 13) a plurality of blades (2) are disposed on the outer edge of the corresponding annular tooth portion (13) on the rotating disk (12), and a toothed disk (21) is disposed between each of the fan blades (2) and the rotating disk (12). The fan blade (2) is assembled with the toothed disc (21), and the toothed disc (21) is pivoted on the rotating disc (12) with a pivot (22), so that the toothed disc (21) can be rotated on the disc (12) rotating upward, and the toothed disc (21) is engaged with the annular tooth portion (13), and a reset elastic member (23) is provided on the toothed disc (21), and the return elastic member (23) is further The end is fixed to the rotating disk (12).

In this way, when the creation is in a static state, each of the blades (2) is in an inwardly folded state [please refer to the second diagram of the creation of the creation state diagram of the creation], and when used When the rotary power source (11) of the driving device (1) is activated, please refer to the third figure, which is shown in the schematic diagram of the local operation state of the creation, that is, the rotating power source (11) can drive the rotating disk ( 12) rotating, and during the rotation of the rotating disc (12), engaging the toothed disc (21) of each vane (2) by the annular tooth portion (13) on the rotating disc (12) to pass the ring The toothed portion (13) drives the toothed disc (21) to rotate, and at the same time cooperates with the centrifugal force to allow the respective blades (2) to rotate synchronously outwardly [please refer to the fourth figure for the fan blade unfolding state of the present invention. Fig. 5 and Fig. 5 are schematic views showing the unfolded state of the fan blade of the present invention]; when the user turns off the rotary power source (11) of the driving device (1), the teeth of each blade (2) can be utilized. The reset elastic member (23) provided on the disk (21) is pulled, and the toothed disk (21) drives the fan blade (2) to rotate back and then enters the inwardly folded state.

According to the above description, the composition of the creation structure and the implementation description can be seen that, compared with the existing structure, the creation is mainly based on the fact that the driving device uses the annular tooth portion to synchronously drive the rotation of the toothed disc of each blade. Each blade can achieve synchronous unfolding action, so as to reduce the occurrence of fault damage, and to extend its service life, and to increase the utility performance characteristics in its overall implementation.
