Description

a smart umbrella

technical field

The invention relates to the technical field of the umbrella manufacturing industry, and in particular provides an intelligent umbrella.

Background technique

Umbrella is a kind of instrument of covering rain and snow, props on the top of people's head position in rainy or snowy weather, prevents people from being drenched by rain or snow. In China, the umbrella was invented by Lu Ban's wife in 1000 BC, and it was not until the 18th century in England that umbrellas began to be used. For thousands of years, the design and manufacture of umbrellas have been continuously improving. From the structural design of umbrellas, it includes straight umbrellas, two-fold umbrellas, three-fold umbrellas, hand-open umbrellas, automatic umbrellas, etc.; , oil paper umbrella, cloth umbrella, nylon umbrella, etc.; from the appearance design, there are more types. So far, the development of umbrellas is still progressing along the traditional direction, and its purpose is to improve the convenience, multi-purpose and attractive appearance of umbrellas.

When using an umbrella, due to the limitation of the umbrella's rain-shielding area, the person holding the umbrella often needs to adjust the direction and position of the umbrella in his hand according to the rainy conditions to avoid being wet by the rain, especially when the umbrella area is relatively small and there is wind Even more so. In rainy and windy weather, the rain often does not fall vertically from the sky to the ground, but falls obliquely to the ground, so it is called floating wind and rain. In this case, the rain falls in real time with the change of wind direction Change, the wind blows from east to west, and the rain will also fall from east to west. At the same time, the rain also changes in the direction of falling with the change of wind force. In the state of light wind, the rain is only slightly shifted from the vertical direction. When rain falls, the rain will be blown more vertically by the wind.

Usually in the case of wind and rain, even if a person holds an umbrella, the rain may fall on the person's body, because the umbrella cannot completely cover the rain coming from the side, so the person holding the umbrella may be rained, especially the head For the following parts of the body, the natural reaction at this time is to slightly tilt the umbrella at an angle, hoping that the center of the umbrella is facing the direction of rain falling, so that you will not be drenched by the rain. However, often this manual adjustment cannot completely cover the rain falling on the person's body. One reason is that the person may not be able to make a correct judgment on the direction of the rain when he is under the umbrella, or even make a judgment in the opposite direction, which will lead to Another reason is that even if the direction of the rain is correctly judged, the actual offset direction of the umbrella cannot be completely consistent with the direction of the rain, resulting in the inability to completely block the wind and rain situation. Moreover, the wind can not only change the direction of the rain, but also blow the direction of the umbrella, causing the rain to fall in the same direction as the umbrella's deviation. body position.

So if there is a device that automatically adjusts the direction and position of the umbrella surface according to the direction of the rain in the umbrella, the umbrella can more avoid people from being drenched by wind and rain.

In recent years, the whole world has been entering the intelligent world. Many tools in life and work have intelligent needs, hoping to bring better experience and convenience to users. However, the intelligent arming of umbrellas is relatively slow at present.

As shown in Figure 1, the embodiment of the present invention includes:

An intelligent umbrella includes an umbrella surface 1, an umbrella frame 2 and an umbrella handle 3. The umbrella surface 1 is arranged on the upper end of the umbrella handle 3 through the umbrella frame 2, and also includes a wind speed and direction sensor 4, a controller 5 and an umbrella handle rotation execution Mechanism 6, the wind speed and wind direction sensor 4 is arranged on the top of the umbrella surface 1, and the umbrella handle rotation actuator 6 is arranged on the umbrella handle 3 to divide the umbrella handle 3 into an upper umbrella handle 31 and a lower umbrella handle 32, The controller 5 is arranged above the umbrella handle rotation actuator 6, and the umbrella handle rotation actuator 6 controls the upper umbrella handle 31 to automatically rotate an angle, so that the upper umbrella handle 31 is in the same direction as the rain falling direction, so that the umbrella handle Surface 1 is at a perpendicular angle to the rain falling direction. Wherein, the length of the upper umbrella handle 31 is smaller than the length of the lower umbrella handle 32 .

In the above, the wind speed and direction sensors include but are not limited to ultrasonic vortex wind speed sensors, propeller wind speed sensors, hot wire wind speed sensors and hot film wind speed sensors.

Further, the smart umbrella also includes a rain speed gear selection device 7 and a signal line 8, the rain speed gear selection device 7 is arranged on the lower umbrella handle 32, the wind speed and direction sensor 4, the controller 5. The umbrella handle rotary actuator 6 and the rain speed gear selection device 7 are connected through a signal line 8 .

Specifically, the wind speed and direction sensor 4 is located on the top of the umbrella, outside the umbrella surface 1, so that the wind speed and wind direction can be more accurately measured, and the controller 5 and the umbrella handle rotary actuator 6 are located in the middle of the umbrella handle 3, and they can be It can be integrated or separately implanted into the umbrella handle 3 . The communication between the wind speed and direction sensor 4 and the controller 5 is carried out through the signal line 8 , and the signal line 8 is located inside the umbrella handle 3 . In addition, as described above: the three levels of rain speed need to be adjusted according to the subjective judgment of the umbrella user on the rainfall intensity, and then this judgment information is transmitted to the controller 5, so that the controller 5 can calculate the angle , so a button with three gear selections (rain speed gear selection device 7) can be set at the umbrella handle 3 below the umbrella, for example, "high" means heavy rain, "medium" means moderate rain, and "low" means light rain , allowing the user to make a selection. According to the user's gear selection, the controller 5 can calculate the rotation angle of the umbrella handle according to the corresponding preset rain speed. And the user can change the gear at any time according to the size of the rain to control the change of the umbrella offset angle. When two direction variables and After obtaining all, just can operate the upper umbrella handle 31 to rotate by the umbrella handle rotation actuator 6. Here, the umbrella handle rotation actuator 6 can use the most conventional angular displacement control equipment to control rotating equipment such as universal joints to drive the rotation of the upper umbrella handle 31 direction.

In the present invention, the smart umbrella can determine the falling direction of the wind and rain in rainy days according to the current wind speed, and determine the direction and angle that the umbrella needs to shift in order to block the wind and rain, and carry out the umbrella surface adjustment according to the size and direction of the wind and rain. Mechanism for orientation adjustment. The main idea is that the umbrella can automatically adjust the direction of the umbrella handle and the umbrella surface according to the direction of the wind and rain, so that it is aligned with the direction of the wind and rain, so as to minimize the chance of the umbrella holder being drenched by the rain and better achieve the effect of blocking the rain. function, such an intelligent umbrella invented an intelligent umbrella control system based on wind speed and direction sensors and universal controllers.

First of all, you need to understand that the formation of wind and rain is directly related to wind direction and wind speed. When the wind blows to the north, the rain will float to the north. The greater the angle of inclination deviates from the vertical. Then there is a relationship between the wind speed and the angle of inclination of the wind and rain. To make the umbrella cover the wind and rain, the angle of inclination of the umbrella (or the angle of inclination of the umbrella handle) must be consistent with the angle of departure of the rain, so the wind speed There is the same relationship with the angle of inclination of the umbrella handle. The following description is to obtain the inclination angle of the wind and rain through the wind speed and wind direction, so as to use this angle to drive the umbrella handle to automatically tilt, so that the umbrella surface is facing the direction of rain falling, that is, the direction of rain falling is in the same direction as the umbrella handle.

Umbrellas are usually made of an umbrella cover, an umbrella frame, an umbrella handle, an umbrella handle and a deployment device, wherein the deployment device includes both manual and automatic forms. Umbrella cover is made of materials such as cloth, plastics or nylon, and its shape comprises triangle, circular arc surface shape etc., but the plane that the umbrella cover bottom forms and umbrella handle are generally in vertical relationship. The umbrella handle rotary actuator 6 designed by the present invention is placed on the umbrella handle 3, and the umbrella handle rotary actuator 6 divides the umbrella handle 3 into upper and lower parts, so the part above the umbrella handle rotary actuator 6 includes the upper umbrella handle 31 , the umbrella surface 1 and the umbrella frame 2, the umbrella handle rotation actuator 6 controls the upper half of the umbrella to automatically rotate an angle according to the direction and speed of the wind, and this angle is the direction of rain falling, so that the upper half of the umbrella handle and the direction of rain falling The same direction, so that the umbrella surface is at a perpendicular angle to the rain falling direction, so as to achieve the function of blocking the wind and rain, and its function realization method is shown in Figure 2.

In this smart umbrella, the control system is its core part, and its system diagram is shown in Figure 3. A simple open-loop control is completely sufficient for this control system.

The system diagram includes three parts: wind speed and direction sensor 4, controller 5 and umbrella handle rotary actuator 6. Arrows indicate input and output variables. Input and output may contain multiple variables or only one variable, so they are represented by thick arrows. The input of the whole system is air pressure or wind force, which depends on the type of wind speed and direction sensor used. At present, wind force and direction sensors include ultrasonic vortex wind speed sensor, propeller wind speed sensor, hot wire wind speed sensor and hot film wind speed sensor, etc. These The sensors measure wind speed and wind direction by measuring data such as ultrasonic time difference, air pressure difference, and heat transfer. Their input quantities may be different, but they all output two variables of wind direction and wind speed. The present invention does not limit the selection and selection of wind speed and wind sensors use.

After obtaining the wind speed and wind direction variables, the next step is to change them into direction information through the controller to control the adjustment of the umbrella handle and the direction of the umbrella surface. This step is completed by using the algorithm of the controller. Calculating angle and orientation information from wind direction information is an important step in this patent. On a rainy day with no wind, the rain falls vertically to the ground. Usually, the rain falls from a height of about 2000 meters. During the fall, it is subjected to the combined force of gravity and air resistance, and the acceleration drops to a uniform drop, so the raindrops finally fall to the ground. It falls at a constant speed, and the speed of falling is related to the size of the raindrops, which is also related to the intensity of the rainfall. The raindrops of drizzle are small in size, so the falling speed is slow, while the raindrops of showers are large in size, and the falling speed is relatively fast. Like a downpour, raindrops are correspondingly larger and therefore fall the fastest. The speed at which rain finally lands is usually called the ending speed of raindrops. There have been related physical theories to describe this problem [1, 2]. Through empirical analysis, the ending speed of raindrops depends on the size of the rain. Roughly in the range of 4m/s-10m/s. The above falling speed of raindrops is the vertical falling speed under no wind conditions.

In the case of wind, the wind force will give the raindrops a horizontal speed, so the speed at which the rain falls is the sum of the vertical speed and the horizontal speed, and the falling direction of the raindrops is also determined by the speed of the two directions. Assuming that the wind speed in the horizontal direction is v1, and the vertical falling speed of rainwater is v2, then the final synthetic speed of rainwater and the angle from the vertical They are:

(1-1),

(1-2),

angle It is through the intelligent umbrella system of the present invention that one of the directions of the umbrella needs to be automatically adjusted, that is, the angle of the upper half of the umbrella handle deviated from the vertical direction. In the process _of calculating this angle, _two speeds v1 and v2 need to be known. _The wind speed v1 in the horizontal direction can be obtained through the wind speed and direction sensor, while the rain speed v2 in the _vertical direction is not so easy to obtain, especially Because the rain itself is wind and rain in a non-vertical direction, it is difficult to accurately calculate the rain speed in the vertical direction.

For the present invention, the rain speed in the vertical direction can be estimated according to the intensity of the rain, and represented by three grades, 4m/s represents the rain speed in light rain, 7m/s represents the rain speed in moderate rain, 10m/s represents the rain speed during heavy rain, use these rain speeds to synthesize with the current wind speed, and obtain the angle that the umbrella needs to deviate from . In a coordinate axis composed of x, y, and z axes (Figure 4), the deviation angle It is the angle between the z-axis and the rain falling process, and the automatic actuator on the umbrella handle needs to adjust the offset direction of the umbrella handle, and it is also necessary to know which direction the umbrella handle deviates from on the xy plane Angle, so it is necessary to obtain the horizontal direction of the wind and rain, and this direction is exactly the direction of the wind. Use to represent the angle between the wind direction and the x-axis.

In summary, using the information from the wind speed and direction sensor and the rain speed subjectively estimated by the umbrella user, two directional variables about the direction of rain falling can be obtained and , and then the controller operates the rotation direction of the umbrella handle according to these two variables.

The traditional umbrella is intelligently optimized, so that this common tool that is necessary for life can bring users a better effect of covering rain and snow on rainy days. The intelligent umbrella of the invention can automatically adjust the direction of the umbrella surface according to the falling direction of the wind and rain, which overcomes the disadvantage that the traditional umbrella cannot completely block the rain under the wind and rain.

To sum up, the smart umbrella of the present invention can use the wind speed and direction sensor to obtain wind speed and wind direction in real time in bad rainy days, especially windy weather, and then calculate the falling direction of the rain, and control the rotation of the umbrella handle according to the direction , so that the umbrella can automatically adjust the direction of the umbrella handle and the umbrella surface according to the falling direction of the rain, so that the umbrella surface is aligned with the falling direction of the raindrops, and better protects the user from the rain.

The above descriptions are only examples of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the description of the present invention, or directly or indirectly used in other related technical fields, shall be The same reasoning is included in the patent protection scope of the present invention.
