Air-free automatic drive structure for sunshade

The invention relates to a power-free automatic driving structure, in particular to a power-free automatic driving structure of a sunshade.

Press; people usually move indoors, and some indoor activities do not need too much sunlight, so people usually add sunshade in the windows of the building to block the sun from entering the building, and block the sunlight from entering the room. It can have "insulation function" and adjust the indoor temperature and lower the room temperature, thereby reducing the chance of opening the air-conditioning and reducing the cost of electricity. It has the effect of "saving energy".

At present, electric curtains are sold on the market, but the use of plug-in method causes a lot of energy waste, is very environmentally friendly, and supplies high-power servo motors, which are quite expensive in price; in addition, there are related intelligent electric curtain control systems. Most of them are provided by European and American manufacturers. The cost of the system is about to be completed at a price of 30,000 to 400,000. This is a place where the average consumer is discouraged.

In addition, although there are curtains that use the energy generated by the conversion of solar energy as a source of power for the body and can be automatically turned on or off, the user does not have to pay extra electricity, but it still has a complicated structure and high price.

Therefore, the current automatic sunshade construction is still not ideal, and based on the "section" If you can design a kind of environmental protection concept that does not need to use solar energy to generate electricity, it can automatically drive the structure of the sunshade completely without electricity, and it can effectively achieve the perfect effect of free electricity, automatic and environmental protection, and the manufacturing cost is low. It can also increase consumers' desire to buy.

Therefore, the inventor's concept of continuous improvement and innovation based on products is based on years of practical experience in product design and development, as well as active research and development thinking, through numerous practical design experiments, resulting in the invention.

The object of the present invention is to provide a shape in which the memory elastic body is deformed by the sunlight to cause the memory elastic body to be deformed to drive the related mechanism to pull down the sheet of the sunshade, thereby automatically changing the angle of the sunshade sheet. The electric power automatic drive structure of the sunshade.

For the purpose of the present invention, the present invention comprises a linkage body, a memory elastic body, a concentrating body, a driving body, and a rotating shaft, wherein the memory elastic body is connected to one side of the linking body at one side, and the memory elasticity is The body is selected from a material that is heated to a predetermined temperature to produce a shape change; the concentrator is selected from the group consisting of a concentrating material, the concentrating body is disposed at a position corresponding to the memory elastic body; and the side of the driving body is coupled to the conjugate body The rotating shaft is coupled to the driving body in a coordinated manner, and the rotating shaft is coupled to the sheet pulling rope of the sunshade in a coordinated manner.

When the sunlight is irradiated to bring the memory elastic body to a predetermined temperature, the memory elastic body is deformed to drive the linkage body, the driving body and the rotating shaft, so that the sheet of the sunshade is pulled up and pulled, and the sheet of the sunshade automatically changes angle. Actions (such as opening or closing a page) have the characteristics of power-free, automatic, environmental protection, temperature control, and low manufacturing cost.

Referring to Figures 1 to 7, the present invention is applied to a sunshade 90, which includes a plurality of sheets 91 and two sheets attached to the sheet 91 and which can be pulled up and down to change the angle of the sheet 91. The sheet pull cord 92 (such as a sheet open or closed) is a conventional structure and will not be described herein. The preferred embodiment of the present invention comprises a linkage body 10, a memory elastic body 20, a concentrating body 30, a driving body 40, and a rotating shaft 50, which are described in detail below.

The linkage body 10 is formed in a link shape; the linkage body 10 is pivotally connected to a bracket 11 for forming The bracket 11 is connected to a fixing member 12, and the fixing member 12 is disposed on the window glass 80 of the building. The fixing member 12 is selected from the double-sided adhesive body.

The memory elastic body 20 is connected to one side of the interlocking body 10, and the memory elastic body 20 is selected from a material which is heated to a predetermined temperature to cause a shape change. The memory elastic body 20 is selected from a memory metal spring; the memory elastic body 20 has one side. A hook portion 21 is provided for hooking the side connected to the linkage body 10.

The concentrating body 30 is selected from a concentrating material, the concentrating body 30 is disposed at a position corresponding to the memory elastic body 20, and the concentrating body 30 is disposed on the window glass 80 of the building.

The driving body 40 is connected to the other side of the linking body 10; the driving body 40 is an inverted U-shaped rack; and the side of the driving body 40 is connected to the other side of the linking body 10 by a flexible body 41 such as a wire; A weight unit 42 is connected to one side of the body 40 for applying gravity to assist in enhancing the driving force of the driving body 40.

The rotating shaft 50 is coupled to the driving body 40 in a coordinated manner, and the rotating shaft 50 is coupled to the sheet pulling rope 92 of the sunshade 90 in a coordinated manner; the rotating shaft 50 includes a driving wheel 51, and the driving wheel 51 is a gear, so that the driving wheel The main shaft 52 is disposed on a side of the main body 52, and a convex body 53 is disposed on the side of the main body 52. The convex body 53 is slidably assembled to the driving wheel 51 for assembling the main body 52 and the driving wheel 51. The separation is configured to form a driving power clutch to control whether the sheet pulling rope 92 is automatically driven. The rotating shaft 50 is further disposed on a fixing base 60 for being disposed on the sunshade 90 by the fixing base 60.

Referring to Figures 8 through 11, when the sunlight illuminates the window glass 80 of the building, the present invention concentrates the sunlight by the concentrating body 30 and illuminates the memory elastic body 20, when the memory elastic body 20 is brought to a predetermined state. When the temperature rises, the memory elastic body 20 will deform upward with the rising temperature, and at the same time, the other side of the linkage body 10 is moved downward to pull the driving body 40 downward to drive The body 40 drives the rotating shaft 50 to rotate, and the rotating shaft 50 rotates to pull up the sheet pulling rope 92 of the sunshade 90, and the sunshade 90 sheet 91 automatically changes the angle of the movement, such as the sheet 91 is closed, so as to block the sunlight from entering the room and having " The heat insulation function can automatically adjust the indoor temperature, which helps to lower the room temperature, and has the characteristics of electricity-free, automatic, environmental protection, temperature control, and low manufacturing cost.

Similarly, when the sunlight is weak and the temperature of the memory elastic body 20 is lowered, the memory elastic body 20 will return to the original state as the temperature is lowered, and the sheet 91 of the sunshade 90 is automatically opened.

Referring to FIG. 12 and FIG. 13 , in an embodiment of the present invention, when the body 52 of the rotating shaft 50 is moved away from the driving wheel 51, the convex body 53 is separated from the driving wheel 51 to form a driving power separation. According to this, the rotating shaft 50 cannot drive the sheet pulling rope 92 of the sunshade 90, and the user can also manually control the sheet pulling rope 92 of the sunshade 90. Therefore, the present invention can be used without changing the sunshade mechanism. Applicable to general sunshade, its practicality is wide.
