Description

Technical Field

[0001] This utility model relates to electric curtains, and more particularly to a drive device for an electric vertical curtain, and an electric vertical curtain using the drive device. Background Technology

[0002] Motorized vertical blinds employ a Venetian blind structure, allowing the slats to move left and right for opening and closing, and also to rotate to change the direction of light transmission. Vertical blinds are increasingly widely used because they can regulate indoor light, provide ventilation, and offer sun shading. The term "vertical blind" as used here includes common vertical blinds, as well as decorative vertical blinds with added sheer curtains, or motorized blinds that differ only in the material of the blind body. Throughout this text, "vertical blind" has the same meaning.

[0003] Vertical blinds use a motor-driven mechanical transmission to control light adjustment and opening / closing. A rotating drive bar (for light adjustment) and a translating drive bar are housed within ball bearings (sliders). These ball bearings slide within a track driven by the transmission mechanism. Hooks are located at the bottom of the ball bearings, and the curtain slats are fixed to these hooks. The translating drive bar controls the opening and closing of the curtain slats; this transmission can be either ball bearings or a synchronous belt. The rotating drive bar rotates the hooks on the ball bearings, controlling the direction of the curtain slats and adjusting the amount of light blocking. This transmission typically uses polygonal drive bars (primarily hexagonal). Because two separate drives are needed to control opening / closing and light adjustment, vertical blind motors generally employ dual-motor drives or a single motor with a clutch switching function.

[0004] Existing vertical blinds, such as the dual-power structure disclosed in Chinese Patent Application No. 202122410472.2, include an opening and closing drive component and a dimming drive component. The opening and closing drive component includes an opening and closing motor assembly and an opening and closing transmission gear set connected to each other. The dimming drive component includes a dimming motor assembly and a dimming transmission gear set connected to each other. The opening and closing motor assembly is generally linear and parallel to the blind track, and the dimming motor assembly is generally linear and perpendicular to the blind track. The opening and closing motor assembly and the dimming motor assembly are arranged in an L-shape at the same end of the blind track. The output end of the opening and closing transmission gear set is connected to the drive pulley of the transmission belt that rotates in the horizontal direction, and the output end of the dimming transmission gear set is connected to the transmission rod.

[0005] In the aforementioned existing technology, transmission components such as gears are directly installed inside the transmission box, which is inconvenient for installation and positioning, and may affect normal operation. Utility Model Content

[0016] Furthermore, the structure of the positioning transmission unit is such that the support base has a second positioning groove for positioning each transmission shaft and a third positioning groove for positioning each bevel gear and the drive gear.

[0017] Furthermore, to facilitate the installation of the drive unit and the transmission unit, the support base includes a first base body and a second base body that are interlocked vertically.

[0031] See Figures 1-5 An electric vertical blind includes a track 100 and a drive unit. The drive unit includes a drive section 200, a transmission section, a first housing 300, and a second housing 400. The first housing 300 may have an L-shaped cross-section and includes a first portion 301 and a second portion 302 that are perpendicular to each other. The first portion 301 is disposed on the side of the track 100 and arranged parallel to the track 100. The second portion 302 is located at one end of the track 100, and the second housing 400 is disposed at the other end of the track 100. The first portion 301 and the second portion 302 are internally interconnected. The first portion 301 of the first housing 300 constitutes a drive housing, and the second portion 302 and the fourth housing 400 constitute a transmission housing. The first housing 300 includes a first half-shell 303 and a second half-shell 304 that interlock vertically to facilitate the installation of internal components.

[0032] The drive unit 200 includes a first drive mechanism 1 and a second drive mechanism 2. Preferably, both drive mechanisms are tubular motors, and the axial directions of the two tubular motors are parallel to each other and parallel to the length direction of the track 100. The first drive mechanism 1 and the second drive mechanism 2 are mainly disposed within the first part 301 of the first housing 300. The first drive mechanism 1 has a first output end with a first bevel tooth 11 disposed thereon, and the second drive mechanism 2 has a second output end with a second bevel tooth 21 disposed thereon.

[0033] The transmission unit includes a driving transmission mechanism and a driven transmission mechanism. The driving transmission mechanism is mainly located in the second part 302 of the first housing 300, and includes a first transmission shaft 31, a second transmission shaft 32, a third transmission shaft 33, a fourth transmission shaft 34, a third bevel gear 35, a fourth bevel gear 36, a fifth bevel gear 37, and a sixth bevel gear 38. The axial directions of the first transmission shaft 31, the second transmission shaft 32, and the third transmission shaft 33 are perpendicular to the axial directions of each driving mechanism, while the axial direction of the fourth transmission shaft 34 is parallel to the axial directions of each driving mechanism.

[0034] The third bevel tooth 35 is fixedly disposed on the outer periphery of the first drive shaft 31, so that the two are coaxial and can rotate synchronously. The first bevel tooth 11 on the first drive mechanism 1 meshes with the third bevel tooth 35, thereby driving the first drive shaft 31 to rotate around its own axis.

[0035] The second drive shaft 32 and the third drive shaft 33 are coaxially arranged and rotate synchronously. They can be integrally formed or separate structures connected to each other (such as keyway fit for synchronous rotation). The fourth bevel gear 36 is fixedly arranged on the outer periphery of the second drive shaft 32, so that the two can rotate synchronously; the fifth bevel gear 37 is fixedly arranged on the outer periphery of the third drive shaft 33, so that the two are coaxial and can rotate synchronously. In this embodiment, the fourth bevel gear 36 is preferably arranged at the end of the second drive shaft 32 away from the third drive shaft 33, and the fifth bevel gear 37 is preferably arranged at the end of the third drive shaft 33 away from the second drive shaft 32. The second bevel gear 21 on the second drive mechanism 2 meshes with the fourth bevel gear 36 on the second drive shaft 32, thereby realizing motion steering. The sixth bevel gear 38 is fixedly arranged on the outer periphery of the fourth drive shaft 33, so that the two are coaxial and can rotate synchronously, and the fifth bevel gear 37 and the sixth bevel gear 38 mesh. The second drive mechanism 2 drives the fourth drive shaft 34 to rotate around its own axis via the second bevel gear 21, the fourth bevel gear 36, the second drive shaft 32, the third drive shaft 33, the fifth bevel gear 37, and the sixth bevel gear 38. The second drive shaft 32 and / or the third drive shaft 33 pass through the first drive shaft 31 and are rotatable relative to the first drive shaft 31.

[0036] The arrangement of the aforementioned drive unit 200 (the first drive mechanism 1 and the second drive mechanism 2 are arranged side by side) and the active transmission mechanism (each drive shaft and bevel gear) reduces the size of the drive device located at the end of the track 100. This size refers to the length dimension along the length direction of the track 100, i.e., as shown below. Figure 3 The dimensions shown in the left-right direction reduce the space occupied.

[0037] The active transmission mechanism also includes an active gear 39, which is fixedly disposed on the outer periphery of the first transmission shaft 31, so that the two can rotate synchronously. The driven transmission mechanism includes a driven gear (not shown) disposed in the second housing 400 and a synchronous belt (not shown) passing around the active gear 39 and the driven gear. The synchronous belt meshes with the active gear 39 and the driven gear respectively. The engagement method of the synchronous belt, the active gear 39 and the driven gear is the same as that of the prior art, and will not be described in detail here.

[0038] A hollow support base 500 is provided inside the first housing 300. The support base 500 contains first positioning grooves 501 for positioning the first drive mechanism 1 and the second drive mechanism 2 of the drive unit 200, second positioning grooves 502 for positioning each transmission shaft, and third positioning grooves 503 for accommodating each bevel gear and the drive gear 39. There are two first positioning grooves 501, which respectively match the first drive mechanism 1 and the second drive mechanism 2. The number and position of the second positioning grooves 502 match each transmission shaft, and the number and position of the third positioning grooves 503 match each bevel gear and the drive gear 39. Alternatively, when the drive unit 200 adopts a scheme with only one drive mechanism (this is prior art), there is also only one first positioning groove 501.

[0039] The first positioning groove 501 and the second positioning groove 502 can each be cylindrical in shape, thereby rotatably supporting the corresponding drive mechanism or transmission shaft. The space of the third positioning groove 503 needs to be larger than the corresponding bevel gears and drive gears 39. For ease of assembly, the support base 500 includes a first base 504 and a second base 505 that interlock vertically, thereby each base forming a semi-cylindrical positioning groove. The semi-cylindrical fit of the two bases results in a cylindrical positioning groove. The first base 504 can be fixed to the first half-shell 303 to form an integral unit, and the second base 505 can be fixed to the second half-shell 304 to form an integral unit.

[0040] The cross-section (horizontal section under normal installation state) of the support base 500 is L-shaped, with one part corresponding to the side of the track 100 and the other part corresponding to the end of the track 100, which is adapted to the distribution of the drive unit 200 and the transmission mechanism.

[0041] During installation, the drive unit 200 and the transmission mechanism simply need to be placed in their corresponding positioning slots. The transmission mechanism can be lubricated, thus facilitating assembly, and the structure is very simple.
