Description

Technical Field

[0001] The invention relates to the technical field of curtains, in particular to a sunshade curtain with a bottom-mounted driving mechanism. Background Art

[0002] Traditional electric honeycomb blinds must be connected to an external 24V or 220V power supply. However, most Chinese families are currently in the process of improving their housing conditions. A considerable number of people do not reserve power interfaces when designing interior decoration, and can only use manually driven products, which greatly reduces the user experience.

[0003] With the development of the smart home environment, indoor products are moving towards intelligence. Some motor manufacturers have made lithium battery power supply solutions inside the motor, which solves the problem of no reserved power interface in the home. However, the service life of lithium batteries will shorten over time, and users need to charge and replace lithium batteries. Since existing products install batteries and motors above the window, it is necessary to climb above the window when replacing batteries or performing maintenance, which brings great inconvenience and safety hazards to users.

After transmitting it to the second gear 72 on the last second axle, the last second axle transmits the power direction back to the first second axle through the third gear 77, so that the power transmission is more stable, and the second axle pulling the cable 8 can provide a more stable pulling force.

[0039] The first base 5, the first honeycomb curtain 2, and the second base 3 are connected in sequence from top to bottom; the first gear 71 rotates synchronously with the first axle, the second gear 72 and the third gear 77 rotate synchronously with the second axle, there are multiple second axles, each second axle is provided with a second gear 72 and a third gear 77, all the second gears 72 are meshed in sequence, all the third gears 77 are meshed in sequence, and the first gear 71 is meshed with any second gear 72; the battery 9 is electrically connected to the motor 6, one end of the cable 8 is connected to the second axle, and the other end of the cable 8 passes through the diverter 10 and is connected to the first base 5. A through hole is provided on the circumferential side of the second axle, the lower end of the cable 8 passes through the through hole and is tied to the second axle, and the second axle is indirectly driven to rotate by the motor 6, so that the second axle can wind or release the cable 8, so that the second base 3 approaches or moves away from the first base 5, and the first honeycomb curtain is opened and closed.

[0040] Specifically, in one embodiment, a plurality of cables 8 may be provided, and different cables 8 are respectively wound on different second axles, and the plurality of second axles correspond to the plurality of cables 8 one by one, so as to prevent the cables 8 from being entangled with each other.

[0057] The working process of the present invention is:

[0058] Only the first honeycomb curtain is set: the first base 5 is directly mounted on the wall. When shading is not required, the motor 6 is rotated by remote control so that the motor 6 drives the second axle to wind the cable 8, so that the honeycomb curtain shrinks upward, and the second base 3 drives the motor 6, the battery 9, etc. to move upward. When shading is required or the battery 9 needs to be replaced or maintenance is required, the motor 6 is rotated by remote control so that the motor 6 drives the second axle to release the cable 8, so that under the action of its own gravity and the gravity of the second base 3, the first honeycomb curtain 2 stretches downward, and the second base 3 drives the motor 6, the battery 9, etc. to move downward. When the second base 3 moves to the lower end of the window, the second sealing cover 34 is removed, the battery 9 automatically pops out, and then a new battery 9 is replaced. When maintenance is required, the bottom plate 33 can be removed from the second shell 31 to maintain the motor 6 and the battery 9.

[0059] The first honeycomb curtain and the second honeycomb curtain are set at the same time: when the second honeycomb curtain 4 and the first honeycomb curtain 2 are both in the folded state (initial state), the second honeycomb curtain 4 and the first honeycomb curtain 2 are all folded up, and the cables 8 are all wound around the second axle. Fig. 9 shown.

[0060] The motor 6 is powered on and starts working, the second wheel shaft releases the cable 8, and the first honeycomb curtain 2 and the second base 3 fall freely under the action of gravity until the cable 8 is completely released and the second honeycomb curtain 4 is fully opened. Fig.10 shown.

[0061] The motor 6 continues the work of the previous process, and the tension cable 8 is retracted to the second wheel shaft in the opposite direction. Since the deadweight of the second base 3 is greater than the deadweight of the third base 1 and the first honeycomb curtain 2, the first honeycomb curtain 2 and the third base 1 rise under the pulling force of the second wheel shaft until the tension cable 8 is completely retracted, the second honeycomb curtain 4 is closed, and the first honeycomb curtain 2 is fully opened. Fig.11 shown.

[0062] The motor 6 works in the reverse direction, the cable 8 is released from the second wheel shaft, and the second honeycomb curtain 4 and the third base 1 fall freely under the action of their own weight until the cable 8 is completely released and the second honeycomb curtain 4 is fully opened. Fig.10 shown.

[0063] The motor 6 continues to work in the reverse direction, and the cable 8 is retracted into the second wheel shaft in the reverse direction. The first honeycomb shade 2 and the second base 3 rise under the action of the cable 8 until the cable 8 is completely retracted into the second wheel shaft, and the second honeycomb shade 4 and the first honeycomb shade 2 are completely retracted to restore the initial state. Fig. 9 shown.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
