Description

Technical Field

[0001] This utility model relates to the technical field of clothes drying, and in particular to a clothes rack structure. Background Technology

[0002] Because drying clothes is a slow process, and people can't stay home all day or watch over their clothes for a long time, and the weather changes frequently, or in some coastal areas where the weather changes quickly, clothes drying at home may get wet. Therefore, there is a need for devices that can automatically dry or collect clothes.

[0003] An existing solar-powered automatic lifting clothes drying rack for balconies, patent number CN201420783887.1, includes multiple mounting brackets, clothes hanging rods, a control box, a rotary motor, a solar panel mounting bracket, clothes hanging holes, a battery, a retractable drum, a telescopic cord, a hand crank, a gimbal, a solar panel, and a light intensity sensor. The control box contains a control circuit board, which integrates control circuitry including an MSP430 microcontroller, a voltage conversion circuit module, a crystal oscillator circuit module, a reset circuit module, a data storage circuit module, automatic and manual control buttons, a clothes rack raising button, a clothes rack lowering button, a signal processing circuit module, a charging control circuit, a motor driver, and a gimbal driver.

[0004] However, the clothes rack mentioned above only controls the raising and lowering of clothes, but cannot control the forward and backward movement of clothes. Whether the clothes are raised or lowered, they are placed in an unshaded environment, so further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a clothes drying rack structure to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clothes drying rack structure includes a parallel frame, a base plate, and a support rod. A controller is installed at one end of the base plate, and a motor is installed inside the controller. The controller is electrically connected to the motor to control the forward and reverse rotation and start and stop of the motor. A drive shaft is rotatably connected to the base plate, and the output end of the motor is drivenly connected to the drive shaft. The bottom end of the support rod is fixedly connected to the drive shaft. The parallel frame is mounted on top of the base plate via the support rod. A photosensitive sensor for generating a photoelectric effect is fixedly installed on one side of the parallel frame, and the photosensitive sensor is electrically connected to the controller.

[0008] To elaborate further, the upper surface of the controller is equipped with control buttons, which are used to control the swing of the support rod in manual mode.

[0009] To elaborate further, a triangular block is fixedly installed on the inside of the parallel frame, which is used to stabilize the strength of the parallel frame.

[0010] To elaborate further, the support rod includes a pair of active rods and a pair of driven rods. The pair of active rods and the pair of driven rods are symmetrically arranged on both sides of the parallel frame. The top ends of the active rods and the driven rods are rotatably connected to the parallel frame. The bottom end of the active rod is sleeved on both ends of the transmission shaft, and the bottom end of the active rod is fixedly connected to the transmission shaft.

[0011] To elaborate further, the controller also includes a transmission box, with a bearing installed at the end of the transmission box. The transmission shaft passes through the bearing and is rotatably connected to the transmission box via the bearing. Gears are hinged inside the transmission box, including a driven gear, a driving gear, and a transmission gear. The driving gear is fixedly connected to the output end of the motor. The driven gear is sleeved on the transmission shaft and is fixedly connected to the transmission shaft. The transmission gear meshes with both the driven gear and the driving gear.

[0012] To elaborate further, a pair of connecting frames are provided on the base plate, and the connecting frames are fixedly connected to the controller. A limit bar is fixedly installed between the connecting frames. The limit bar is arranged between the drive shaft and the controller. A pair of limit pins are also fixedly installed on the side wall of the drive shaft. A retraction stop button is fixedly installed on the limit bar.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0024] like Figure 1-2As shown, this embodiment provides a clothes rack structure, including a parallel frame 2, a base plate 5, and a support rod. A controller 6 is provided at one end of the base plate 5, and a motor 8 is provided inside the controller 6. The controller 6 is electrically connected to the motor 8 to control the forward and reverse rotation and start and stop of the motor 8. The motor 8 mainly controls the swing of the support rod to achieve the forward and backward movement of clothes. A drive shaft 1 is rotatably connected to the base plate 5. The output end of the motor 8 is connected to the drive shaft 1. The bottom end of the support rod is fixedly connected to the drive shaft 1. Specifically, the active rod 3 (mentioned below) in the support rod is sleeved on the drive shaft 1 and fixed. Therefore, when the drive shaft 1 rotates, it can control the deflection of the support rod. The parallel frame 2 is mounted above the base plate 5 through the support rod, so the deflection of the support rod can control the parallel frame 2 to translate relative to the base plate 5. A photosensitive sensor 9 for generating the photoelectric effect is fixedly installed on one side of the parallel frame 2. The photosensitive sensor 9 is electrically connected to the controller 6. Ambient light is collected by the photosensitive sensor 9 and, through the photoelectric effect, emits an electrical signal to the controller 6. The controller 6 then controls the motor 8 to rotate forward or reverse, or stop at its designated position. The photosensitive sensor 9 is a sensor with an internal photosensitive element that converts light signals into electrical signals. Its sensitive wavelength is near the visible light wavelength, including infrared and ultraviolet wavelengths. The photosensitive sensor converts light energy into electrical signals through the photoelectric effect. The core process is: light irradiation – photoelectric conversion – electrical signal output – signal processing. The photosensitive sensor 9 can be from the Risym 5506 series.

[0025] In this embodiment, the upper surface of the controller 6 is provided with a control button 10, which is used to control the swing of the support rod in manual mode. Because if there is still light after the clothes are dry, it may not be possible to retract them, so button 10 is added. Pressing the up button will cause the motor 8 to reverse 45 degrees, retracting the clothes rack and ending the program. Therefore, in addition to automatic drying and retraction, a manual retraction function is added, which is the manual mode mentioned above. In manual mode, the signal input of the photosensitive sensor 9 will be disconnected.

[0026] In automatic mode, the forward or reverse rotation of motor 8 is determined by the magnitude of ambient light collected by photosensitive sensor 9, which outputs an electrical signal to controller 6. Controller 6 controls the rotation of motor 8 based on the input electrical signal, and controls the swing of support rod to achieve the forward and backward translation of parallel frame 2.

[0027] When the photosensitive sensor 9 detects strong ambient light (sunlight), the motor 8 rotates forward, causing the support rod to extend. One of the driving rods 3 and one of the driven rods 4 are assembled with the base plate 5 and the parallel frame 2 respectively to form an approximate parallelogram. Using the mechanical principle of the instability of the parallelogram, the clothes rack extends. When the photosensitive sensor 9 detects weak ambient light (night, cloudy day, or rainy day), the motor 8 rotates in reverse, causing the support rod to move (causing the clothes rack to retract).

[0028] In this embodiment, a triangular block is fixedly provided on the inner side of the parallel frame 2, and the triangular block is used to stabilize the strength of the parallel frame 2.

[0029] In this embodiment, the support rod includes a pair of active rods 3 and a pair of driven rods 4. The active rods 3 and driven rods 4 are symmetrically arranged on both sides of the parallel frame 2. The top ends of the active rods 3 and driven rods 4 are rotatably connected to the parallel frame 2. The bottom ends of the active rods 3 are sleeved on both ends of the transmission shaft 1, and the bottom ends of the active rods 3 are fixedly connected to the transmission shaft 1. The bottom ends of the driven rods 4 are rotatably connected to the base plate 5. When the motor 8 rotates, it controls the active rods 3 to move the parallel frame 2. Because the active rods 3 are fixed to the transmission shaft 1, the driven rods 4 oscillate passively as the parallel frame 2 moves, thus providing support for the parallel frame 2.

[0030] In this embodiment, the controller 6 also includes a transmission box 7. A bearing is installed at the end of the transmission box 7. The transmission shaft 1 passes through the bearing and is rotatably connected to the transmission box 7 through the bearing. Gears are hinged inside the transmission box 7. The gears include a driven gear, a driving gear, and a transmission gear. The driving gear is fixedly connected to the output end of the motor 8. The driven gear is sleeved on the transmission shaft 1 and is fixedly connected to the transmission shaft 1. The transmission gear meshes with the driven gear and the driving gear respectively.

[0031] The following details the limiting conditions of parallel frame 2 in each state:

[0032] A pair of connecting frames are fixedly extended on the base plate 5, and a limiting crossbar 11 is fixedly installed between the connecting frames. The connecting frames are fixedly connected to the controller 6. Specifically, the limiting crossbar 11 is arranged between the drive shaft 1 and the controller 6. At the same time, a pair of limiting pins 12 are also fixedly installed on the side wall of the drive shaft 1. When the photosensitive sensor 9 detects low ambient light (night, cloudy day, or rainy day), the motor 8 reverses and drives the support rod to move, causing the clothes rack to retract. The aforementioned pair of limiting pins 12 will move along with the drive shaft. The reverse rotation of shaft 1 gradually approaches the limit bar 11 until it abuts against the retraction stop button 13 on the limit bar 11. The retraction stop button 13 is embedded and fixed on the side wall of the limit bar 11. The retraction stop button 13 is electrically connected to the controller 6. The limit stop pin 12 can press the retraction stop button 13 to stop the continuous reverse rotation of motor 8, and the limit stop pin 12 deflects and abuts against the limit bar 11; the parallel frame 2 also achieves the effect of stable limit during retraction. The parallel frame 2 is located above the base plate 5.

[0033] An upwardly extending limiting frame is fixedly installed at the front end of the base plate 5. The limiting frame is provided with a pair of limiting rods 14 extending outward at both ends. One of the limiting rods 14 has an extension stop button 15 on its surface. When the extension is in place, the driven rod 4 will flip outward and finally abut against the extension stop button 15 of the limiting rod 14. This extension stop button 15 is electrically connected to the internal controller 6. When the extension stop button 15 is pressed by the driven rod 4, it can stop the continuous forward rotation of the motor 8. At the same time, the limiting rod 14 can provide a stable limit for the driven rod, and the parallel frame 2 can be stably kept in the extended state for drying.

[0034] For the stability of this utility model, the base plate 5 should be fixed to the place where it is used during actual use.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
