[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] Example 1: A remote control structure for a double single-pole clothes drying rack includes a remote controller, a signal receiving module 1, a first main control module 2, a second main control module 3, a power supply module, and two action modules. The remote controller and the signal receiving module 1 are connected wirelessly via signal transmission. The signal receiving module 1 is also electrically connected to the first main control module 2. The first main control module 2 is electrically connected to the second main control module 3 and one of the action modules, which controls the raising and lowering of one clothes drying pole in the double single-pole clothes drying rack. The second main control module 3 is electrically connected to the other action module, which controls the raising and lowering of the other clothes drying pole in the double single-pole clothes drying rack. The power supply module is electrically connected to the signal receiving module 1, the first main control module 2, the second main control module 3, and the two action modules. The first main control module 2 receives signals from the signal receiving module 1 and controls the connected action module to perform actions based on the signal content, or transmits the signals to the second main control module 3, which then controls the connected action module to perform actions. This achieves individual control of the two connected single-pole clothes drying racks and avoids interference between remote control signals. It should be noted that in this example, the method used by the first main control module 2 to control the action module or transmit the signals to the second main control module 3 after receiving the signals is an existing method, such as adding identifiers to the radio frequency signals to distinguish the action mechanisms. Furthermore, the methods used by the first main control module 2 and the second main control module 3 to control the action modules are also existing control methods, such as using existing chips to drive DC motors. This example describes the use of two single-pole clothes drying racks together. In some special cases, the connection between the first main control module 2 and the second main control module 3 can be disconnected, allowing one single-pole clothes drying rack to be used independently, achieving a flexible combination effect.

[0020] The signal receiving module 1 includes a receiving module based on a 315MHz or 433MHz remote control frequency; in this example, a remote control method based on a 433MHz frequency signal is used. Compared with the 315MHz band, this frequency band has stronger penetration and anti-interference capabilities, and is less likely to be affected by the obstruction of damp clothing.

[0021] The receiving module includes a receiving chip U1; the VDD pin of chip U1 is the power input pin, connected to the power supply VCC through resistor R2. The two ends of resistor R2 are also grounded through capacitors C3, C4, and C5, respectively, with capacitors C3 and C4 connected in parallel at the end of resistor R2 closest to the VDD pin of chip U1; the XIN pin of chip U1 is the frequency reference pin for an external crystal oscillator, connected to crystal oscillator X1, which is also grounded; the VSS pin of chip U1 is the ground pin; the ANT pin of chip U1 is the signal input pin, connected to antenna E1 through inductor L2. Inductor L2 is used to increase the capacitive reactance of antenna E1 and optimize signal reception performance. The two ends of inductor L2 are also grounded through inductors L1 and L3, respectively; antenna E1 is also grounded through capacitor C1; the DO pin of chip U1 is used as the modulation signal output pin and connected to connector CN1, which is connected to the first main control module 2. The CTH pin of chip U1 is grounded through capacitor C7; the VREG pin of chip U1 is grounded through capacitor C2; and the EN pin of chip U1 is connected to the power supply VCC. The receiver chip U1 can be an existing XC4366A RF receiver chip. The first main control module 2 includes connector CN2, a first control chip U2, a first communication transceiver chip U3, and connector CN3. Connector CN2 is connected to pin 433 of the first control chip U2, which is responsible for receiving and modulating signals. The first control chip U2 is also connected to the first communication transceiver chip U3. The first communication transceiver chip U3 is connected to connector CN3, which is used to connect to the second control module. The second main control module 3 includes connector CN4, a second control chip U4, and a second communication transceiver chip U5. Connector CN4 is used to connect to connector CN3 in the first main control module 2. It should be noted that connector CN4 is not directly connected to connector CN3, but is connected through external wiring. In this example, both the first communication transceiver chip U3 and the second communication transceiver chip U5 are communication chips based on the RS485 protocol, so the two connectors are connected through a communication line based on the RS485 protocol. Connector CN4 is also connected to the second communication transceiver chip U5. The second communication transceiver chip U5 is also connected to the second control chip U4.

[0022] The action module includes an action motor and an LED light group; the action motor and LED light group in the two action modules are electrically connected to the control chip U2 in the first main control module 2 and the control chip U4 in the second main control module 3, respectively; on the one hand, it realizes the action control of the clothes drying pole in a single-pole clothes drying machine, and on the other hand, it can also realize the lighting, which facilitates the operation of drying or collecting clothes.

[0023] A clothes drying rack includes the aforementioned control structure, two clothes drying rods, and two housings. A signal receiving module 1, a first main control module 2, a power supply module, and an action module are housed within one of the housings. A second main control module 3 and another action module are housed within the other housing. The action modules within both housings are connected to the two clothes drying rods via ropes to control the raising and lowering of the clothes drying rods. One end of one housing houses the signal receiving module 1, which contains the first main control module 2, a power supply module, and an action module. The other housing houses the second main control module 3, a power supply module, and an action module. The first and second main control modules 2 and 3 are connected via a 485 communication line 4. It should be noted that the housing corresponding to the second main control module 3 does not contain the signal receiving module 1.

[0024] During remote control operation, signal receiving module 1 receives the remote control signal via antenna E1. After data processing by chip U1, the signal is transmitted to connector CN2 via connector CN1. Communication between connector CN1 and connector CN2 is established via... Figure 1 The signal is connected via connector CN2 and sent to the first control chip U2 for analysis. If the target of the signal is the first single-pole clothes drying rack where the first control chip U2 is located, it is directly sent to the corresponding action module to execute the remote control command. If the target of the signal is the second single-pole clothes drying rack, it is sent to connector CN4 via connector CN3. Connectors CN3 and CN4 communicate via... Figure 1 The 485 communication line 4 is connected, and then the connector CN4 sends the data to the second control chip U4. The second control chip U4 then sends the data to the corresponding action module, so as to ensure that the double single-pole clothes drying racks can operate synchronously while the clothes drying racks can also operate independently.
