Description

Lightweight electric umbrella

The invention relates to a lightweight electric umbrella, in particular to a method that not only enables a user to control the umbrella bone unfolding or collapsing of the umbrella by electricity, but also can control the unfolding of the umbrella bone of the umbrella according to different use needs. The angle makes it easier and more convenient in the process of operation and use, and it has more practical features in its overall implementation and use.

Press, in the outdoor environment with strong sunlight, in order to protect the skin, prevent skin tanning and sunburn, and at the same time avoid direct sunlight to the human body to generate high temperature and heat, so parasols will be used to block direct sunlight to the human body; In addition, in In rainy days, in order to avoid getting wet by rain during outdoor activities, umbrellas are often used to block rain from getting wet.

Regardless of whether it is a parasol or an umbrella, etc., its structural design is generally a mechanical structure design, which requires the user to push and pull the umbrella bone to expand and collapse the umbrella bone. However, since this type of umbrella requires the user to force the operation to unfold and collapse the umbrella bone, causing inconvenience in use, it has also been studied by industry players. Automatically controlled umbrellas are issued so that the umbrella bones of the umbrellas can be automatically unfolded and closed by using keys.

However, although the above-mentioned umbrellas with automatic control can achieve the expected effect of automatically expanding and collapsing the umbrella bones with the control of buttons, it has also been found in the overall practical use that these types of structures are designed for mechanical structures and can only be used. Simply controlling the umbrella bone to directly expand and collapse does not allow the user to slowly expand and collapse the umbrella bone with one hand according to different use requirements, site constraints, and other factors, resulting in inconvenience in the operation and use process. As a result, there is still room for improvement in the overall structural design.

The reason is that the inventor has taken this into consideration, and with many years of rich design, development, and actual production experience in the relevant industry, he researched and improved the existing structure and defects, and provided a lightweight electric umbrella to achieve better practical value.
