Description

Technical Field

[0001] The present invention belongs to the technical field of electric curtain rods, and in particular relates to a magnetic trackless electric curtain rod with a built-in motor and a method for using the same. Background Art

[0002] Electric curtain rods upgrade traditional manual curtain operation to electric control. Driven by a built-in motor, they utilize a transmission mechanism to move the curtains along a track, enabling automatic opening, closing, and adjustment, providing a convenient and intelligent home experience. Users can easily control the opening and closing of curtains using a remote control, mobile app, or smart home system, meeting lighting and privacy requirements in various scenarios.

[0003] Currently, most electric curtain rods on the market use a track design, relying on fixed tracks to guide the movement of the curtains. This makes installation relatively complex and space-intensive. Furthermore, the motor of existing electric curtain rods is tightly connected to the transmission system. If a motor malfunctions, such as damage, a short circuit, or a malfunctioning control system, the entire transmission system loses power, rendering the curtains inoperable. This not only creates inconvenience for users but also disrupts their daily lives and experience by preventing them from operating the curtains in an emergency, such as when shading or protecting privacy is a necessity.

[0009] Furthermore, the driven component includes a fixed tube, which is installed at the other end inside the curtain rod. A second U-shaped fixing frame is provided in the driven component.

[0014] This solution also discloses a method for using a magnetic trackless electric curtain rod with a built-in motor, which mainly includes the following steps: Step 1: Put the curtain on the curtain rod, with the first bevel gear and the second bevel gear between the curtain ring. When the user pulls the curtain open, the third ring magnet is on the right side of the second ring magnet. The curtain ring is used to push the third ring magnet to move to the left, and the third ring magnet is used to push the second ring magnet to move to the left until the fourth ring magnet moves to the left side of the first ring magnet. The movement of the second ring magnet drives the plastic sleeve to move, and the movement of the plastic sleeve drives the synchronous belt transmission, thereby driving the second synchronous pulley and the third synchronous pulley to rotate. The rotation of the third synchronous pulley drives the third rotating shaft to rotate. The rotation of the third rotating shaft drives the light-sensing turntable to rotate. The rotation of the light-sensing turntable triggers the photoelectric sensor. The photoelectric sensor is connected to the motor. The output end of the motor rotates to drive The second bevel gear rotates, and the second bevel gear rotates to drive the first bevel gear to rotate. The first bevel gear rotates to drive the first rotating shaft to rotate. The first rotating shaft rotates to drive the first gear to rotate. The first gear rotates to drive the second gear to rotate. The second gear rotates to drive the second rotating shaft to rotate. The second rotating shaft rotates to squeeze the magnetic beads out of the first groove, and the magnetic beads are stuck in the second groove through the circular hole. At this time, the fixing pin moves to the end of the slot, so that the second rotating shaft rotates to drive the sleeve to rotate. The sleeve rotation drives the second synchronous pulley to rotate. The second synchronous pulley rotates to drive the synchronous belt transmission. The synchronous belt transmission drives the second ring magnet to move to the left, and the first ring magnet is used to push the fourth ring magnet to move to the left, so that the third ring magnet is used to push the curtain ring to open the curtain; Step 2: When the user pulls up the curtain, the fourth ring magnet is on the left side of the first ring magnet, and the curtain ring is used to push the third ring magnet to move to the right, and the fourth ring magnet pushes the first ring magnet to move to the right until the third ring magnet moves to the right side of the second ring magnet. The movement of the second ring magnet drives the plastic cover to move, and the movement of the plastic cover drives the synchronous belt transmission, thereby driving the second synchronous pulley and the third synchronous pulley to rotate. The rotation of the third synchronous pulley drives the third rotating shaft to rotate, and the rotation of the third rotating shaft drives the light-sensing turntable to rotate. The rotation of the light-sensing turntable triggers the photoelectric sensor. The photoelectric sensor is connected to the motor. The output end of the motor rotates in the opposite direction to drive the second bevel gear to rotate, and the second bevel gear rotates The first bevel gear is driven to rotate, and the rotation of the first bevel gear drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft squeezes the magnetic beads out of the first groove, and the magnetic beads are stuck in the second groove through the circular hole. At this time, the fixing pin moves to the end of the slot, so that the second rotating shaft rotates to drive the sleeve to rotate, and the rotation of the sleeve drives the second synchronous pulley to rotate. The rotation of the second synchronous pulley drives the synchronous belt transmission. The synchronous belt transmission drives the second ring magnet to move to the right, and the second ring magnet is used to push the third ring magnet to move to the right, so that the fourth ring magnet is used to push the curtain ring to pull the curtain up.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: The present invention provides a magnetic trackless electric curtain rod with a built-in motor, which achieves the following beneficial effects: (1) The motor is built into the curtain rod, which improves the appearance of the curtain rod.

[0016] (2) The setting of the synchronous component. When the power is off, the curtains can be opened and closed manually. When the motor is stationary, the second synchronous pulley can rotate left and right at will. The rotation of the motor output end drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first bevel gear to rotate. The rotation of the first bevel gear drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the second rotating shaft to rotate. The rotation of the second rotating shaft squeezes the magnetic beads out of the first groove.
