Technical Field
[0001] This utility model belongs to the field of double-window louver technology, and particularly relates to a double-window linkage louver device. Background Technology
[0002] Venetian blinds are windows that use slats that can be rotated to adjust the amount of light entering the room, thus achieving a balance between light control and ventilation. Venetian blinds usually use a single-pane structure, but for some large windows, a double-pane structure is used to meet the needs due to material performance and adaptability to the external environment.
[0003] Common double-pane venetian blinds often feature a double-window structure. The drive mechanism uses electric technology combined with gear transmission to drive the venetian blinds to deflect. However, due to the complex external environment, the venetian blind blades need to have strong structural stability to withstand the complex external environment. The conventional drive mechanism in a single-pane structure cannot meet the structural stability requirements of the double-window linkage structure during the deflection process. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0028] This utility model embodiment provides a double-window linkage louver device, such as Figures 1-6 As shown, the double-window linkage louver device includes:
[0029] An outer frame 100 has a middle frame in the middle, which divides the outer frame 100 into two independent areas;
[0030] The first louver assembly 210 and the second louver assembly 220 are located in different independent areas. The first louver assembly 210 and the second louver assembly 220 are driven synchronously by a drive unit located inside the middle frame.
[0031] The first louver assembly 210 includes an active blade 211 and several sets of driven blades 212. A connecting rod 230 connects the active blade 211 and the driven blades 212. The connecting rod 230 includes a main rod 231 and several sets of support rods 232. The support rods 232 are hinged to the main rod 231. The support rods 232 are fixedly connected to the active blade 211 and several sets of driven blades 212 respectively. The driven blades 212 will rotate synchronously with the deflection of the active blades 211.
[0032] The middle frame is equipped with a drive unit, which includes a drive motor 310, a transmission worm gear 320 and a transmission worm 330. The drive motor 310 is connected to the transmission worm 330. The transmission worm gear 320 includes a shaft 321 and a worm wheel 322 mounted on the shaft 321. The shaft 321 has shaft hole fixing seats 324 at both ends. The first louver assembly 210 and the second louver assembly 220 are respectively connected to different shaft hole fixing seats 324.
[0033] In this embodiment, the worm gear structure is used as the main driving mechanism to drive the deflection of the active blade 211. The self-locking stability principle of the worm gear reduces the fluctuations generated by the active blade 211 and the driven blade 212 when affected by external factors, and at the same time reduces the torque generated by the fluctuations on the motor, thus reducing the damage to the motor. In addition, the transmission worm gear 320 adopts a dual-axis output structure to provide support for the first louver assembly 210 and the second louver assembly 220. The worm gear structure design can meet the stability requirements of the double-sided structure and reduce the impact of the external environment on the overall structural stability of the double louvers.
[0034] As a preferred embodiment of this invention, the outer frame 100 is mainly composed of crossbeams and uprights. In this application, the rectangular area formed between the crossbeams and uprights in the outer frame 100 is divided into two areas by the middle frame. A first louver assembly 210 and a second louver assembly 220 are respectively provided in the different areas. The first louver assembly 210 and the second louver assembly 220 have the same structure.
[0035] Taking the arrangement of the first louver assembly 210 area as an example, the active blade 211 is provided with a deflection shaft 2111 and a rotation shaft 2112 at both ends, and the driven blade 212 is only provided with a rotation shaft 2112 at both ends. The upright and the middle frame are provided with several sets of shaft holes or bearing seats that can be assembled with the rotation shaft 2112, providing a fulcrum for the rotation connection of the rotation shaft 2112. The deflection shaft 2111 at one end of the active blade 211 needs to be inserted into the shaft hole fixing seat 324 with a drive unit inside the middle frame, and the drive unit drives the active blade 211 to rotate.
[0036] In this embodiment, the deflection shaft 2111 must adopt an irregular structure. The deflection shaft 2111 is structurally compatible with the shaft hole fixing seat 324. When the shaft hole fixing seat 324 rotates with the shaft 321, the deflection shaft 2111 rotates under the action of the irregular structure. The rotating shaft 2112 can adopt a common cylindrical structure, as long as the rotating shaft 2112 rotates along with it.
[0037] In this embodiment, the active blade 211 and the driven blade 212 are connected by a connecting rod 230. The connecting rod 230 includes a main rod 231 and several sets of support rods 232. The support rods 232 are hinged to the main rod 231. The support rods 232 are fixedly connected to the active blade 211 and several sets of driven blades 212 respectively. The support rods 232 and the active blade 211 and the support rods 232 and the driven blades 212 are both inclined. The inclination angle between the support rods 232 and the active blade 211 and the inclination angle between the support rods 232 and the driven blades 212 are the same. The linkage principle of the connecting rod 230 is based on the prior art. The main principle is not described in detail here, but can be referred to the existing technical means.
[0038] In a preferred embodiment of this invention, the middle frame is provided with a rotating hole communicating with the outside. The rotating hole mainly accommodates the deflection shaft 2111 extending into it. A mounting bearing 340 is provided inside the rotating hole, and the shaft hole fixing seat 324 is mounted on the inner edge of the mounting bearing 340. The shaft hole fixing seat 324 is rotatably connected to the middle frame body through the mounting bearing 340.
[0039] In this embodiment, the inner frame is hollow, and the rotation hole is opened in the side wall of the shell of the inner frame. The drive motor 310 is fixedly assembled on the inner wall of the inner frame, and the transmission worm gear 320 is assembled and connected to the inner frame through the assembly bearing 340; the corresponding support structure is simplified. Here, the drive motor 310 is equipped with a corresponding controller and control motherboard, and its principle is the same as the control principle of electric louvers in the prior art. The controller can be set on the outer frame 100 with a panel structure or can be implemented by wireless remote control. Here, the electronic control technology refers to the technical principle of existing electric louvers.
[0040] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
