DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 5 As shown, a multi-layer energy-saving curtain wall includes a window frame, an outer curtain wall 2, and an inner curtain wall 3. The outer curtain wall 2, the inner curtain wall 3, and a sunshade mechanism are installed on the window frame from the outside to the inside. The sunshade mechanism includes a first sunshade roller blind 41 and a second sunshade roller blind 42. The window frame includes an upper frame box 51 and a lower frame box 52. A first motor 43 and a second motor are installed in the upper frame box 51. The first motor 43 is connected to a first sunshade shaft 431 in a transmission manner, and the first sunshade roller blind 41 is wound on the first sunshade shaft 431. The second motor is connected to a second sunshade shaft 432 in a transmission manner, and the second sunshade roller blind 42 is wound on the second sunshade shaft 432. The lower frame box 52 is connected to a first sunshade shaft 431 in a transmission manner, and the second sunshade roller blind 42 is wound on the second sunshade shaft 432. It has steps, and the steps include a first step surface 521 and a second step surface 522. The height of the first step surface 521 is higher than that of the second step surface 522. Two clamping angles 6 are symmetrically installed on the first step surface 521, and two clamping angles 6 are also symmetrically installed on the second step surface 522. A first limiting plate 411 is also installed on one side of the first sunshade roller blind 41, and the first limiting plate 411 is aligned with the two clamping angles 6 with higher heights and clamped and limited thereto. A second limiting plate 421 is also installed on one side of the second sunshade roller blind 42, and the second limiting plate 421 is aligned with the two clamping angles 6 with lower heights and clamped and limited thereto.

[0020] The first sunshade roller blind 41 in the present invention is a prior art sunshade roller blind of darker color, and the second sunshade roller blind 42 is a prior art sunshade roller blind of lighter color.

[0021] When the first sunshade roller curtain 41 is moved downwards, the sunshade shaft 431 is rotated to move the first motor 43 to the first sunshade shaft 431, and the first motor 43 drives the first sunshade roller curtain 41 on the first sunshade shaft 431 to be lowered. When the first limiting plate 411 is lowered and close to the two clamping angles 6 directly below, the operator can manually clamp the first limiting plate between the two clamping angles 6, which is conducive to completely shading and fixing the first sunshade roller curtain 41 when it is spread downwards, and prevents the first sunshade roller curtain 41 from leaking light into the room, which is conducive to a good sunshade effect. Similarly, the sunshade effect can also be achieved through the second sunshade roller curtain 42, and the color of the second sunshade roller curtain 42 is lighter. When the sunlight intensity is low, the second sunshade roller curtain 42 can be used. This can not only provide good sunshade, but also avoid the indoor opacity and poor light caused by the overly dark color of the sunshade. The first sunshade roller curtain 41 and the second sunshade roller curtain 42 can be flexibly switched, which is highly practical.

[0022] like Figures 1 to 5 As shown, the clamping angle 6 includes a first button 61, a pressure rod 63, a first groove 64, and a first clamping groove 65. The clamping angle 6 is provided with a first groove 64, and the first clamping groove 65 is provided on the first groove 64 of the clamping angle 6. Elastic limiting members are installed on both ends of the first limiting plate 411 and the second limiting plate 421. The elastic limiting member is limitedly connected with the first clamping groove 65. The clamping angle 6 also has a first channel 66 connected to the first groove 64. A pressure rod 63 is installed on the first button 61. The pressure rod 63 passes through the first channel 66 and abuts against the elastic limiting member.

[0023] During use, the elastic limit members of the first sunshade roller curtain 41 and the second sunshade roller curtain 42 are limitedly clamped in the first groove 64 of the clamping angle 6. If the operator wants to rewind them, he can first press the first button 61 on the side of the clamping angle 6. The first button 61 drives the pressure rod 63 to be pressed in the direction of the elastic limit member until the elastic limit member is pushed out of the first groove 64 by the thrust of the pressure rod 63, and then rewinded to the original rewinding position through the first motor 43. The setting of this structure is conducive to facilitating the rewinding or lowering and fixing of the first sunshade roller curtain 41 and the second sunshade roller curtain 42, and has a simple structure and is easy to operate.

[0024] The first spring 661 in the present invention is prior art.

[0025] like Figures 1 to 5As shown, a plurality of first springs 661 are installed in the first channel 66, and the button also has a first stopper, which is connected to the first spring 661 and is used to restore the button to its original state after being pressed. Through the first spring 661 and the first stopper, the first button 61 can be restored to its original position by the elastic potential energy of the first spring 661 itself after being pressed, which is convenient for the next use and has strong practicality.

[0026] like Figures 1 to 5 As shown, a second clamping groove 67 is further provided at the bottom of the first groove 64 of the clamping angle 6, and the bottoms of the first limiting plate 411 and the second limiting plate 421 both have a clamping portion 422, and the clamping portion 422 is clamped and limited with the second clamping groove 67.

[0027] The clamping and limiting of the clamping portion 422 and the second clamping groove 67 facilitates better insertion of the first sunshade roller curtain 41 and the second sunshade roller curtain 42 into the two second clamping grooves 65 of the clamping corners 6 located directly below them, and the structure is stable.

[0028] like Figures 1 to 5 As shown, the elastic limiting component includes a second spring 71 and a second limiting block 72. Second grooves are provided at both ends of the first limiting plate 411 and the second limiting plate 421. The second spring 71 is installed in the second grooves of the first limiting plate 411 and the second limiting plate 421. The second limiting block 72 is fixedly connected to the second spring 71. The second limiting block 72 is limitedly connected to the first clamping groove 65 and abuts against the pressure rod 63.

[0029] The second limit block 72 abuts against the pressure rod 63. When the button is pushed toward the elastic limit member, the pressure rod 63 presses the second limit block 72 out of the first groove 64, and presses the second limit block 72 into the second grooves at both ends of the first limit plate 411 and the second limit plate 421. The second spring 71 contracts, which is convenient for converting the first sunshade roller curtain 41 or the second sunshade roller curtain 42 from a fixed locked state to a retractable state. The structure is simple and the operation is convenient.

[0030] like Figures 1 to 5 As shown, a control button 8 is installed on the upper frame box 51, which is used to start the first sunshade roller blind 41 and the second sunshade roller blind 42. Through the control button 8, the first motor 43 and the second motor can be started to drive the first sunshade roller blind 41 and the second sunshade roller blind 42 to roll up or unfold and lower the sunshade, which is conducive to convenient operation.
