Description

Technical Field

[0001] This invention belongs to the field of umbrellas, specifically relating to a self-regulating intelligent adaptive umbrella based on hybrid energy technology. Background Technology

[0002] Rainy days cause visibility to be significantly reduced due to rainwater splashing through the windshields and rearview mirrors of vehicles, and the reflection of light from wet pavement further diminishes visibility. This poses a safety hazard to pedestrians, necessitating an umbrella with warning capabilities to alert passersby and vehicles to avoid the area. Existing umbrellas often fail to provide complete protection from rain, a problem that this invention aims to address. Furthermore, this umbrella can also be used as a sunshade on sunny days.

[0003] Previous researchers invented warning umbrellas powered by pressure sensors and batteries, which have a good warning function for rainy days and other weather with poor visibility. However, they still have problems such as inaccurate measurement of rainfall levels, inability to achieve self-powering, and cumbersome battery replacement.

[0004] The piezoelectric effect refers to the polarization that occurs when certain dielectric materials are deformed by an external force in a certain direction, resulting in opposite charges appearing on their two opposing surfaces. Therefore, piezoelectric patches can be used to collect the energy generated by raindrops vibrating on the surface of an umbrella.

[0005] Flexible photovoltaic panels have the advantages of being foldable and easy to carry compared to traditional photovoltaic panels. Therefore, in this invention, flexible photovoltaic panels are attached to the surface of umbrellas to serve as a source of solar energy absorption on sunny days.

[0006] Current current control methods in constant-frequency switching converters or switch-mode power converters typically provide output regulation through duty cycle control. This means adjusting the ratio of the on-time to the off-time of the power switching device to respond to changes in input or output voltage. In this respect, commonly used duty cycle control and current-mode control are similar; both achieve output regulation by adjusting the duty cycle. However, they differ in that commonly used duty cycle control can only adjust the duty cycle based on changes in output voltage, while current-mode control adjusts the duty cycle based on changes in the main (power) inductor current.

[0007] Compared to existing warning umbrellas, this invention utilizes the piezoelectric effect, employing piezoelectric patches to collect the vibrational energy of rainwater. An energy regulation chip adjusts the unstable current to a more stable one, and an energy analysis chip determines the rainfall level based on the current magnitude. Furthermore, based on the rainfall intensity, wind and rain angle, ultraviolet radiation intensity, and solar radiation angle analyzed by the energy analysis chip, this invention intelligently adjusts the electrically rotating telescopic rod, altering the umbrella's appearance to achieve sun and rain protection. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, this invention provides a self-regulating intelligent adaptive umbrella technology based on hybrid energy technology.

[0009] A self-adjusting intelligent adaptive umbrella based on hybrid energy technology includes an umbrella body, which includes an umbrella handle, umbrella ribs mounted on the umbrella handle, and an umbrella canopy mounted on the umbrella ribs. A piezoelectric patch is disposed on the inner side of the umbrella canopy, and the piezoelectric patch generates electrical energy through deformation. A battery is disposed on the umbrella body to store the electrical energy generated by the piezoelectric patch.

[0010] Furthermore, a piezoelectric patch is circumferentially arranged on the inner side of the umbrella canopy, and the piezoelectric patch is connected to the umbrella frame.

[0011] Furthermore, a flexible photovoltaic panel is provided on the outer side of the umbrella canopy, which generates photovoltaic power and stores the electrical energy in a battery.

[0012] Furthermore, an ultraviolet sensor is provided on the outer side of the umbrella canopy to detect ultraviolet rays.

[0013] Furthermore, an energy analysis module is provided on the umbrella body, which receives and analyzes current information.

[0014] Furthermore, the umbrella body is equipped with a smart display and a warning light.

[0015] Furthermore, it also includes an umbrella canopy telescopic assembly, which includes a telescopic umbrella fabric and several electric telescopic rods. The telescopic umbrella fabric has a ring structure, with the side closer to the umbrella canopy connected to the umbrella surface and the side farther from the umbrella canopy connected to the electric telescopic rods. Several electric telescopic rods are arranged around the edge of the umbrella surface and connected to the umbrella ribs, which are used to drive the telescopic umbrella fabric to unfold and retract.

[0016] Furthermore, the umbrella canopy telescopic assembly has two parts, one for sunny weather with a sunshade telescopic umbrella fabric, and the other for rainy weather with a rain-proof telescopic umbrella fabric.

[0017] Furthermore, it also includes several rotary motor assemblies arranged around the edge of the umbrella canopy and connected to the umbrella ribs. The rotary motor assemblies are used to drive the umbrella canopy telescopic assembly to rotate, so as to adjust the tilt angle of the umbrella canopy telescopic assembly.

[0018] The outer side of the umbrella canopy is equipped with a flexible photovoltaic panel, which generates photovoltaic power and stores the electrical energy in a battery.

[0019] The inner side of the umbrella canopy is uniformly covered with piezoelectric patches;

[0020] The outer side of the umbrella canopy is uniformly covered with ultraviolet sensors, which are used to detect ultraviolet rays.

[0021] An energy analysis module is installed on the umbrella body, and the energy analysis module receives and analyzes current information.

[0022] The umbrella body is equipped with a smart display and a warning light;

[0023] It also includes an umbrella telescopic assembly, which includes a telescopic umbrella fabric and several electric telescopic rods. The telescopic umbrella fabric has a ring structure, with the side closer to the umbrella cane connected to the umbrella surface and the side farther from the umbrella cane connected to the electric telescopic rods. Several electric telescopic rods are arranged around the edge of the umbrella surface and connected to the umbrella ribs, which are used to drive the telescopic umbrella fabric to unfold and retract.

[0024] The umbrella canopy telescopic assembly has two parts, one for sunny days and the other for rainy days. The latter has the other part for rainy days and the other part for rain protection.

[0025] When rain falls on the umbrella surface, the piezoelectric patch generates current due to vibration. The energy analysis chip analyzes the rainfall intensity and the angle of the raindrops falling, and outputs the shape parameters that the umbrella surface telescopic component needs to change in rainy weather to the smart display. The umbrella surface telescopic component changes its length and angle to unfold the rain-proof telescopic umbrella fabric so that the umbrella holder can both avoid the rain and see the road ahead. At the same time, the smart display controls the warning light to turn on.

[0026] When it is sunny, the flexible photovoltaic panel absorbs solar energy, and the ultraviolet sensor transmits the ultraviolet intensity data to the smart display. The smart display outputs the shape parameters that the umbrella canopy telescopic component needs to change on sunny days. The umbrella canopy telescopic component changes its length and angle to unfold the umbrella canopy to provide shade for the person holding the umbrella.

[0027] The beneficial effects of this invention are:

[0028] Based on the piezoelectric effect, this invention uses piezoelectric patches to collect the vibration energy of rainwater. The unstable current is regulated into a more stable current in the energy regulation chip. The rainfall level can be determined based on the magnitude of the current in the energy analysis chip. Based on the rainfall intensity and slant angle, ultraviolet intensity and sun irradiation angle obtained from the energy analysis chip, this invention can intelligently adjust the umbrella canopy extension component to change the appearance of the umbrella to achieve the function of sunshade and rain protection.

Detailed Implementation

[0036] In the description of this invention, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] Please see Figures 1-6 A self-regulating intelligent adaptive umbrella based on hybrid energy technology includes an umbrella body, which comprises an umbrella handle 3, several umbrella ribs 2 arranged around the upper end of the umbrella handle 3, and an umbrella canopy 1 laid on the umbrella ribs 2. Several piezoelectric patches 5 are evenly arranged around the inner side of the umbrella canopy 1. The outer side of the umbrella canopy 1 is the side used for sun and rain protection, and the inner side is the side not used for sun and rain protection. The piezoelectric patches 5 are correspondingly connected to the umbrella ribs 2. When raindrops fall onto the umbrella canopy 1, they vibrate, and the piezoelectric patches 5 attached to the umbrella canopy 1 generate current due to deformation. A battery 10 is installed inside the umbrella handle 3 to store the electrical energy generated by the piezoelectric patches 5.

[0039] Among them, the piezoelectric patch 5 is installed on the inner side of the umbrella canopy 1. At the same time, several rectangular areas are cut on the umbrella canopy 1 so that some of the piezoelectric patch 5 can extend from the rectangular areas and be attached to the outer side of the umbrella canopy 1. Waterproof adhesive is then applied to the rectangular areas to ensure that the piezoelectric patch 5 is tightly attached to the umbrella canopy 1.

[0040] Furthermore, a flexible photovoltaic panel 8 and a warning light 4 are installed on the outer side of the umbrella canopy 1. The flexible photovoltaic panel 8 consists of one or more panels arranged in a uniform ring. Multiple warning lights 4 are arranged in a ring around the outer side of the umbrella canopy 1 and connected to the umbrella ribs 2. A row of ultraviolet sensors 7 is installed in the middle of each flexible photovoltaic panel 8. An energy analysis module 9 is installed inside the umbrella handle 3, which receives and analyzes current information. Additionally, a sunny-day umbrella canopy extension assembly and a rainy-day umbrella canopy extension assembly are installed on the outer edge of the umbrella canopy 1. A rotary motor assembly 15 is installed at the end of the umbrella ribs 2 furthest from the umbrella handle 3.

[0041] Among them, multiple sets of piezoelectric patches 5 generate current due to deformation after raindrops fall onto the umbrella surface 1. The current is transmitted to the energy analysis chip 9 via wire. The unstable current is adjusted into a more stable current in the energy analysis chip 9 and then stored in the battery 10 for later use. The chip also analyzes the amount of rainfall, analyzes which part of the umbrella surface receives more rainfall and the distribution of rainfall locations based on the strength of the piezoelectric signal, and analyzes the extension length and rotation angle of the electric telescopic rod.

[0042] Among them, multiple sets of flexible photovoltaic panels 8 are installed on the umbrella surface 1, which absorb solar energy and convert it into electrical energy, which is transmitted to the energy analysis chip 9 to generate a relatively stable output current, which is then stored in the battery 10 for later use.

[0043] The intelligent display 6 is installed on the outer periphery of the middle part of the umbrella cane 3. It has the functions of displaying, analyzing and calculating, and operating, and serves to show the umbrella holder the rainfall situation and intelligently adjust the length and rotation angle of the electric telescopic pole. Each umbrella rib 2 is equipped with a set of warning lights 4, which serves to warn pedestrians and vehicles in low visibility conditions during rainy days.

[0044] Among them, the ultraviolet sensor 7 is installed in the middle of the flexible photovoltaic panel 8 of each part of the umbrella surface 1 to detect the ultraviolet intensity. Based on the ultraviolet intensity on different umbrella surfaces, the surface of the umbrella being irradiated is analyzed to obtain the angle of sunlight at this time, and the ultraviolet intensity and the angle of sunlight are transmitted to the smart display 6.

[0045] The rotating motor assembly 15 comprises multiple units arranged in a ring around the umbrella cane 3. The housing of the rotating motor assembly 15 contains two micro-motors, one above the other. Both the sunny-day and rainy-day umbrella canopy telescopic components are installed and adjusted via the rotating motor assembly 15. Specifically, the sunny-day umbrella canopy telescopic component includes a sunny-day telescopic umbrella fabric 13 and several sunny-day electric telescopic rods 16. The sunny-day telescopic umbrella fabric 13 is a ring-shaped structure made of black rubber material. Its side closer to the umbrella cane 3 connects to the umbrella surface 1, while its side further away from the umbrella cane 3 connects to the sunny-day electric telescopic rods 16. Several sunny-day electric telescopic rods 16 are arranged around the edge of the umbrella surface 1 and connected to the output shaft of the micro-motor located at the upper end of the rotating motor assembly 15. The sunny-day electric telescopic rods 16 are used to drive the sunny-day telescopic umbrella fabric 13 to unfold and retract, and the rotating motor assembly 15 is used to drive the sunny-day umbrella canopy telescopic component to adjust its tilt angle. The rain-day umbrella retractable assembly is located at the lower end of the sunny-day umbrella retractable assembly. It includes a rain-day retractable umbrella fabric 12 and several rain-day electric retractable rods 11. The rain-day retractable umbrella fabric 12 has a ring structure and is made of transparent plastic material. The side of the fabric closer to the umbrella cane 3 is connected to the umbrella surface 1, and the side away from the umbrella cane 3 is connected to the rain-day electric retractable rods 11. Several rain-day electric retractable rods 11 are arranged around the edge of the umbrella surface 1 and are connected to the output shaft of the micro motor located at the lower end of the rotary motor assembly 15. The rain-day electric retractable rods 11 are used to drive the sunny-day retractable umbrella fabric 13 to unfold and retract. The rotary motor assembly 15 is used to drive the rain-day umbrella retractable assembly to adjust the tilt angle.

[0046] This invention adjusts the telescopic umbrella assembly based on the ultraviolet intensity and solar irradiation angle obtained from the energy analysis chip 9 and the ultraviolet sensor 7, thus unfolding the telescopic umbrella fabric 13 for sunny weather. The umbrella holder can adjust the length and angle of the electric telescopic pole 16 for sunny weather on the smart display 6, or the smart display 6 can automatically adjust it according to the actual situation.

[0047] This invention adjusts the umbrella canopy telescopic assembly based on the rainfall intensity and oblique wind and rain angle obtained from the energy analysis chip 9, thus unfolding the telescopic umbrella fabric 12. The umbrella holder can adjust the length and angle of the electric telescopic pole 11 on the smart display 6, or the smart display 6 can automatically adjust it according to the actual situation.

[0048] like Figure 4 As shown, the present invention mainly consists of two main circuits. The first circuit is composed of a piezoelectric patch 5, an energy analysis chip 9, a storage battery 10, a smart display 6, a warning light 4, a rotary motor 15, and a rain-day electric telescopic pole 11, which is mainly suitable for rainy days. The second circuit is composed of a flexible solar panel 8, an energy analysis chip 9, a storage battery 10, a smart display 6, an ultraviolet sensor 7, a rotary motor 15, and a sunny-day electric telescopic pole 16, which is mainly suitable for sunny days.

[0049] Working principle of the invention:

[0050] When rain falls on the umbrella canopy 2, the piezoelectric patch 5 generates current due to vibration. The energy analysis chip 9 analyzes the rainfall intensity and the position of the rain on the umbrella canopy. The intelligent display 6 outputs the shape parameters that the umbrella canopy telescopic component needs to change in rainy weather. The umbrella canopy telescopic component changes its length and angle, unfolding the rain-proof telescopic umbrella fabric 12 so that the umbrella holder can both avoid the rain and see the road ahead. At the same time, the intelligent display 6 controls the warning light 4 to turn on.

[0051] When it is sunny, the flexible photovoltaic panel 8 absorbs solar energy, and the ultraviolet sensor 7 transmits the ultraviolet intensity data to the smart display 6. The smart display 6 outputs the shape parameters that the umbrella canopy telescopic component needs to change on sunny days. The umbrella canopy telescopic component changes its length and angle, and unfolds the umbrella canopy 1 to provide shade for the umbrella holder.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
