[0002] In recent years, with the rise of smart homes, smart clothes drying racks, as a home product, have officially carried a new concept of life and represent the arrival of the smart era of balcony homes. The clothes drying racks based on indoor balconies have been greatly improved. Indoor clothes drying racks have become smarter, faster and more practical, but the clothes drying racks based on outdoor carriers have not improved much. Most of the outdoor clothes drying racks currently used by people are traditional clothes drying racks that cannot automatically shrink with changes in the external environment. If it rains, fogs, is cloudy, at night, is windy or hot and hot weather, traditional clothes drying racks cannot protect clothes hung outdoors from rain, dew, sun exposure and falling off. The outdoor smart clothes drying racks on the market are costly, not highly intelligent and inconvenient to operate, so outdoor smart clothes drying racks have not been widely used.

[0008] Furthermore, a slide groove is provided on the fixing plate, one end of the driving rod of the scissor-type telescopic frame 2 is slidably connected to the slide groove through a pin, and the other end is connected to the nut.

[0009] Furthermore, a plurality of pulleys are installed on the rainproof shield rod, one end of the steel wire rope is fixed on the guide rod, the steel wire rope passes around the plurality of pulleys in sequence in the middle, and the other end is wound on the winding wheel.

[0010] Furthermore, the transmission ratio i of the driving gear and the sixth driven gear is 1 =100; the transmission ratio i of the driving gear and the eighth driven gear 2 =1.

[0011] Furthermore, the speed n of the first motor is 1 =300r / min.

[0012] Furthermore, the rainproof shield rod is an arched circular tube.

[0013] Furthermore, the reel comprises a reel for reeling up the rainproof cloth and a clockwork spring arranged at the end of the reel.

[0014] Furthermore, a control system of an intelligent outdoor clothes drying rack includes a temperature sensor for collecting temperature signals of the external environment, a humidity sensor for collecting humidity signals of the external environment, a photosensor for collecting light intensity signals of the external environment, a photoelectric three-cup wind sensor for collecting wind intensity signals in the external environment, and a controller; the controller receives and analyzes the temperature signal, humidity signal, light intensity signal, and wind intensity signal; when the temperature signal value is greater than a set temperature threshold and / or the humidity signal value is greater than a set humidity threshold and / or the light intensity signal value is less than a set light threshold and / or the wind intensity signal value is greater than a set wind threshold, the controller sends instructions to the first motor and the second motor, so that the first motor drives the rainproof side panel to close and the winding wheel to retract the wire rope, and the second motor drives the scissors-type telescopic frame to retract.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1-Figure 2 As shown, a specific embodiment of an intelligent outdoor clothes drying rack of the present invention includes a fixing plate 1 fixed on a wall, a scissors-type telescopic frame 2 and a driving mechanism 3 for driving the scissors-type telescopic frame 2 to extend and retract are connected to the fixing plate 1; the driving mechanism 3 includes a lead screw 31 coaxially mounted with the output shaft of a second motor 34, and a nut 32 sleeved on the lead screw 31, the nut 32 is connected to the driving rod of the scissors-type telescopic frame 2, when the second motor 34 receives an extension or retraction command, one end of the driving rod of the scissors-type telescopic frame 2 slides up and down on the fixing plate 1 through a pin, and the other end moves forward and backward following the nut 32.

[0030] like Figure 1-Figure 4As shown, a rain shield mechanism is installed on the fixed plate 1, and the rain shield mechanism includes rain shield side plates 4 vertically hinged at the left and right ends of the fixed plate 1, rain shield rods 5 arranged at the left and right ends of the front side of the fixed plate 1 and adapted to the rain shield side plates 4, a reel 6 arranged at the lower end of the rain shield rod 5, a guide rod 7 installed across the two rain shield rods 5, a rain shield cloth 8 with two ends respectively installed on the reel 66 and the guide rod 7, a guide wheel 9 installed on the guide rod 7 and rolling along the rain shield rod 5, a first motor 10 installed on the fixed plate 1, a driving gear 11 coaxially connected to the first motor 10, a first driven gear 12 externally meshed with the driving gear 11, a second driven gear 13 coaxially connected to the first driven gear 12, and a third driven gear 14 externally meshed with the second driven gear 14. The driven gear 14 and the fourth driven gear 15, the fifth driven gear 16 coaxially connected to the third driven gear 14, the sixth driven gear 17 externally meshed with the fifth driven gear 16, the first bevel gear 20 coaxially connected to the fourth driven gear 15, the second bevel gear 21 externally meshed with the first bevel gear 20, the seventh driven gear 18 coaxially connected to the second bevel gear 21, the eighth driven gear 19 externally meshed with the seventh driven gear 18, the winding wheel 22 coaxially connected to the eighth driven gear 19, the wire rope connected to the guide rod 7 and the winding wheel 22 at both ends, the first connecting rod 23 fixedly mounted on the sixth driven gear 17, the second connecting rod 24 hinged to the first connecting rod 23; the second connecting rod 24 is rotatably connected to the rainproof side plate 4. According to the design requirements, the output shaft of the first motor 10 is coaxially connected to the driving gear 11, and the transmission ratio i between the driving gear 11 and the sixth driven gear 17 is set. 1 =100, the transmission ratio i between the driving gear 11 and the eighth driven gear 19 2 =1, and the operating speed of the first motor 10 is set to n 1 =300r / min, where the speed n of the sixth driven gear 17 is 6 =3r / min, the speed n of the eighth driven gear 19 8 =300r / min, to fully unfold the rainproof cloth, the winding wheel 22 needs to pull the wire rope 25 times, and the opening and closing of the rainproof side plate 4 causes the sixth driven gear 17 connected to the first connecting rod 23 to rotate 1 / 4 circle. The design length of the first connecting rod 23 is 80mm, and the design length of the second connecting rod 24 is 50mm, thereby ensuring that the rainproof side plate 4 and the rainproof cloth 8 play a role in rainproofing at the same time, and the whole process is completed within 5 seconds.

[0031] See also Figures 1 to 5When the weather changes, the temperature sensor 28 for collecting the temperature signal of the external environment, the humidity sensor 27 for collecting the humidity signal of the external environment, the photosensitive sensor 30 for collecting the light intensity signal of the external environment, and the photoelectric three-cup wind sensor 29 for collecting the wind intensity signal in the external environment are used to collect the external environment signal, and then the external environment signal is transmitted to the controller 35. The controller 35 receives the temperature signal, humidity signal, light intensity signal and wind intensity signal and analyzes them. When the temperature signal value is greater than the set temperature threshold and / or the humidity signal value is greater than the set humidity threshold and / or the light intensity signal value is less than the set light threshold and / or the wind intensity signal value is greater than the set wind threshold, the controller 35 sends instructions to the first motor 10 and the second motor 34, so that the first motor 10 drives the rainproof side plate 4 to close and the winding wheel 22 to retract the wire rope, and the second motor 34 drives the scissors-type telescopic frame 2 to retract. When the external environment is suitable for drying clothes, the humidity sensor 27 collects the humidity signal of the external environment, the light intensity signal of the external environment collected by the photosensor 30, and the wind intensity signal of the external environment collected by the photoelectric three-cup wind sensor 29, and the controller 35 processes and feeds back to the first motor 10 and the second motor 34, thereby realizing automatic drying of clothes. The humidity sensor model used in the embodiment of the present invention is DHT11, the temperature sensor model is PT100, and the photosensor model is OMRON-EESX771.

[0032] This design adopts an infrared control module. The device used in the infrared remote control module is an infrared integrated receiving probe VS1838B. The infrared receiver receives the infrared signal generated by the remote control. The controller 35 receives the carrier signal and responds to the received signal according to the set program to control the movement of the first motor 10 and the second motor 34. Therefore, the user can control the clothes drying rack through the remote control and choose whether to collect clothes or set the time for drying clothes.

[0033] like Figure 1-Figure 7As shown, the control system of the intelligent outdoor clothes drying rack, when the clothes are collected manually, the controller 35 receives the infrared remote control signal. At this time, if the scissor-type telescopic frame 2 is in the unfolded state, the controller 35 sends an instruction to the second motor 34, so that the second motor 34 reverses and retracts the scissor-type telescopic frame 2, and completes the manual collection of clothes. When the humidity sensor 27 detects that the external environment is raining or / and foggy or / and the humidity is heavy, the controller 35 sends to the second motor 34 and the first motor 10, so that the scissor-type telescopic frame 2 is retracted and the rain shielding mechanism is unfolded, so as to realize the rain protection of clothes. When there is no rain or foggy or heavy humidity in the external environment, when the light intensity signal of the external environment detected by the photosensitive sensor 30 and the temperature signal of the external environment detected by the temperature sensor 28 are too high, the controller 35 can be sent to the second motor 34 and the first motor 10 according to the time set by the user, so as to drive the scissor-type telescopic frame 2 to retract and the rain shielding mechanism to unfold, thereby realizing the protection of clothes from the sun. When the detected external temperature signal is too small and / or the light intensity is too weak, the scissor-type telescopic frame 2 is retracted and the rain shielding mechanism is unfolded, so as to realize the function of automatically collecting clothes when it is dark. When the wind strength signal collected by the photoelectric three-cup wind sensor 29 is too strong, the controller 35 sends a command to retract the scissor-type telescopic frame 2 and unfold the rain shield mechanism to prevent the clothes from falling off. When the external environment signals detected by the temperature sensor 28, the humidity sensor 27, and the photosensor 30 are suitable for drying clothes, the controller 35 sends a command to the first motor 10 and the second motor 34, and the first motor 10 and the second motor 34 reverse to unfold the rain shield mechanism and the scissor-type telescopic frame 2, thereby realizing the automatic drying function.

[0034] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
