DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1 - Figure 3 The utility model discloses an intelligent curtain lifting drive structure, including a shell 1, a working chamber 2 is arranged in the hollow interior of the shell 1, a driving shaft 3 for retracting and releasing curtain cloth is rotatably connected in the working chamber 2, one end of the driving shaft 3 passes through the shell 1 and is connected to a driving mechanism 4, an avoidance groove 5 connected to the working chamber 2 is arranged at the bottom of the shell 1, an auxiliary roller 6 for assisting curtain cloth retraction and release is rotatably connected to the working chamber 2 above the avoidance groove 5, and a connecting component 7 is arranged at the bottom of the shell 1 on the side of the avoidance groove 5 away from the driving shaft 3.

[0023] In this embodiment, when it is necessary to control the curtain to be lowered, the controller sends a signal to the signal receiver 44, so that the signal receiver 44 controls the motor 41 to run, and then the motor 41 drives the worm 43 to rotate, so that the worm wheel 42 rotates and drives the drive shaft 3 to rotate. At this time, the drive shaft 3 puts down the curtain to complete the lowering of the curtain.

[0024] While the curtain passes through the avoidance groove 5 and descends, the curtain will first contact the auxiliary roller 6, and the auxiliary roller 6 is arranged above the avoidance groove 5, so that the curtain can avoid the inner wall of the avoidance groove 5 during the falling process, thereby avoiding contact between the curtain and the shell 1, which can effectively reduce the noise generated by friction. At the same time, the contactless curtain retraction and release method can reduce the wear of the curtain during use and extend the service life of the curtain.

[0025] When the curtain needs to be rolled up, the controller also sends a signal to the signal receiver 44, so that the signal receiver 44 controls the motor 41 to reverse and drive the drive shaft 3 to reverse and roll up the curtain. During the rising process of the curtain, it will also be restricted by the auxiliary roller 6 to prevent the curtain from contacting the inner wall of the avoidance groove 5 during the rising process.

[0026] In a further preferred embodiment of the present invention, Figure 2As shown, the driving mechanism 4 includes a motor 41, a worm wheel 42, a worm 43, a signal receiver 44 and a driving box 45, one side of the driving box 45 is fixedly connected to the housing 1, the internal rotation of the driving box 45 is provided with a worm wheel 42 fixedly connected to the driving shaft 3, the bottom of the driving box 45 is fixedly connected to the motor 41, the output shaft of the motor 41 is fixedly connected to the worm 43 meshing with the worm wheel 42, and the inner wall of the driving box 45 is fixedly connected to the signal receiver 44 for controlling the motor 41.

[0027] In this embodiment, because the motor 41 generates slight noise during operation, and the gear collision sound of the transmission part during operation also generates noise, the superposition of noises will make the smart curtain lifting drive mechanism appear very noisy during use, affecting the user experience. Therefore, by arranging a worm wheel 42 and a worm 43 as transmission parts, the use noise of the smart curtain lifting drive mechanism can be reduced by utilizing the characteristics of smooth transmission and low noise, thereby improving the user experience.

[0028] In a further preferred embodiment of the present invention, Figure 3 As shown, a heat dissipation hole 8 is provided on the outer wall of the driving box 45 near the signal receiver 44 .

[0029] In this embodiment, because the signal receiver 44 is arranged in the driving box 45, the heat generated by the signal receiver 44 during operation is difficult to dissipate, which will affect the operating stability of the signal receiver 44 and reduce the life of the signal receiver 44. Therefore, a heat dissipation hole 8 is provided on the side of the driving box 45 close to the signal receiver 44 to avoid overheating of the signal receiver 44 and affect the operating stability, thereby extending the service life of the signal receiver 44.

[0030] At the same time, the setting of the heat dissipation holes 8 can also reduce the obstacles when the signal receiver 44 receives signals, improve the sensitivity of the signal receiver 44, and further improve the user experience of the smart curtains.

[0031] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the inner wall of the driving box 45 is adhered with a sound-absorbing cotton 9 , and the sound-absorbing cotton 9 is away from the signal receiver 44 .

[0032] In this embodiment, by adhering silencer cotton 9 inside the drive box 45, the noise generated during the operation of the drive mechanism 4 can be further reduced, giving the user a better experience. The provision of silencer cotton 9 will also affect the dissipation of heat. Therefore, silencer cotton 9 is not provided at the signal receiver 44 to prevent the silencer cotton 9 from affecting the heat dissipation of the signal receiver 44.

[0033] In a further preferred embodiment of the present invention, Figure 2As shown, the connecting assembly 7 includes a connecting rail 71, a connecting slider 72 and a counterweight 73. The top of the connecting rail 71 is fixedly connected to the shell 1, and the bottom of the connecting rail 71 is provided with a sliding groove and is slidably connected with a connecting slider 72 for clamping the curtain. The counterweight 73 is arranged below the shell 1.

[0034] In this embodiment, by clamping the connecting slider 72 at the free end of the curtain and then inserting the connecting slider 72 into the connecting track 71, the curtain is folded when in use, which can further improve the light-shielding property of the curtain.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, the counterweight member 73 is composed of a counterweight roller 731 and a connecting plate 732. Two connecting plates 732 are provided, and two counterweight rollers 731 are rotatably connected between the two connecting plates 732. A gap is reserved between the two counterweight rollers 731 for the curtain to pass through.

[0036] In this embodiment, the counterweight 73 is provided to apply a downward pulling force to the curtain, which can be used to ensure the stability of the curtain when it is retracted and released, and avoid wrinkles on the curtain when it is retracted and released.

[0037] At the same time, the setting of the counterweight 73 can also make the bottom end of the curtain located between the connecting track 71 and the auxiliary roller 6, which can avoid the curtain from contacting the inner wall of the side of the avoidance groove 5 away from the auxiliary roller 6, and further ensure that the curtain will not make noise due to friction during use.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
