Detailed Implementation Methods

[0035] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] like Figures 1-6 As shown, this utility model embodiment provides a telescopic plate drive assembly 100, including: a fixed base 1, a drive mechanism 2, a gearbox 3, a gear transmission mechanism 4, and a chain transmission mechanism 5.

[0037] The mounting base 1 has a receiving space for accommodating the drive mechanism 2 and for mounting the fixed gearbox 3. The drive mechanism 2 is fixed inside the mounting base 1. The gearbox 3 is fixed on opposite sides of the mounting base 1; the gear transmission mechanism 4 is fixed between the two gearboxes 3, and the input end of the gear transmission mechanism 4 is connected to the drive mechanism 2. The drive mechanism 2 drives the gear transmission mechanism 4. A chain transmission mechanism 5 is connected to the output end of the gear transmission mechanism 4. By installing the telescopic plate drive assembly 100 inside the movable screen, after pushing the movable screen to a designated position, the drive mechanism 2 is activated to drive the gear transmission mechanism 4, which in turn drives the chain transmission mechanism 5 to telescopically extend and retract, thereby locking or unlocking the movable screen. For example, when the movable screen is in a spacious environment, by fixing the telescopic plate drive assembly 100 above and / or below the movable screen, activating the telescopic plate drive assembly 100 to telescopically extend and retract achieves bidirectional contact and fixation between the ceiling and the floor, thus securing the movable screen. When it's time to release, simply retract the telescopic plate drive assembly 100 to its original position to unlock it, then remove the movable screen. This automatic fixing via the telescopic plate drive assembly 100 makes installation convenient. Simultaneously, it minimizes the impact of installation on the drive mechanism's performance and prevents damage to the telescopic plate drive assembly 100 if improperly installed.

[0038] In this embodiment, the chain drive mechanism 5 includes a sprocket 51, a sprocket rail 52 fixed to the gearbox 3, a support frame 53, and a chain 54 disposed on the support frame 53.

The sprocket rail 52 is used to guide the chain 54. The chain 54 is connected to a telescopic plate, and the drive mechanism 2 drives the sprocket 51 to rotate, thereby adjusting the movement of the chain 54 to achieve the telescopic and fixed effect of the movable screen.

Meanwhile, the first arc-shaped portion 524 is also used to house a sprocket 51, which facilitates the sprocket 51 and the first arc-shaped portion 524 to limit the chain 54 passing between them, prevent the chain 54 from moving or deviating, and achieve high transmission efficiency.

The opposite ends of the fixing rods 531 are respectively fixed to the two gearboxes 3. The two ends of the concave arc portion 534 are respectively fixed to one end of the first support plate 532 and one end of the second support plate 533.

The outer periphery of the sprocket 51 is directly opposite the concave arc portion 534. The inner side of the chain 54 is respectively disposed on the first support plate 532, the raised arc portion 535, and the second support plate 533. The first support plate 532 and the second support plate 533 facilitate support for the chain 54. The first support plate 532 is disposed on the side close to the base 521, and the second support plate 533 is disposed on the side away from the base 521.

[0041] In this embodiment, the drive mechanism 2 includes a motor 21 fixed to the fixed base 1 and a worm gear 22 sleeved and fixed to the output shaft of the motor 21; the worm gear 22 is connected to the input end of the gear transmission mechanism 4. The motor 21 drives the worm gear 22 to rotate, thereby driving the gear transmission mechanism 4 to move, and the gear transmission mechanism 4 drives the chain transmission mechanism 5 to achieve telescopic movement.

[0042] In this embodiment, the gear transmission mechanism 4 includes a first-stage gear 41, a second-stage gear 42, a third-stage gear 43, a fourth-stage gear 44, and a transmission shaft 45, which are respectively installed on the gearbox 3.

[0043] The input end of the first-stage gear 41 is connected to the worm gear 22, the output end of the first-stage gear 41 is connected to the input end of the second-stage gear 42, the output end of the second-stage gear 42 is connected to the input end of the third-stage gear 43, and the output end of the third-stage gear 43 is connected to the fourth-stage gear 44. One end of the drive shaft 45 is fixed to the fourth-stage gear 44, and the sprocket 51 is sleeved and fixed to the end of the drive shaft 45 away from the fourth-stage gear 44. The motor 21 drives the worm gear 22 to drive the first-stage gear 41 to rotate, which in turn drives the second-stage gear 42 to rotate, which in turn drives the third-stage gear 43 to rotate, which in turn drives the fourth-stage gear 44 to rotate. The rotation of the fourth-stage gear 44 drives the drive shaft 45 to rotate, which in turn drives the sprocket 51 to rotate, thus achieving the movement of the chain 54.

[0044] In this embodiment, the first stage gear 41 includes a first rotating shaft 413, a turbine 412 and a first gear 411 sleeved and fixed to the first rotating shaft 413; the first rotating shaft 413 is rotatably connected to the gearbox 3, and the turbine 412 meshes with the worm gear 22.

[0045] The second stage gear 42 includes a second rotating shaft 423, and a second gear 421 and a third gear 422 sleeved and fixed to the second rotating shaft 423; the second gear 421 meshes with the first gear 411.

[0046] The third-stage gear 43 includes a third rotating shaft 433, and a fourth gear 431 and a fifth gear 432 sleeved and fixed to the third rotating shaft 433, wherein the third gear 422 meshes with the fourth gear 431.

[0048] In this embodiment, the first gear 411 moves coaxially with the turbine, the second gear 421 moves coaxially with the third gear 422, the fourth gear 431 moves coaxially with the fifth gear 432, and the sixth gear 441 moves coaxially with the sprocket 51. The diameters of the first gear 411, the third gear 422, the fifth gear 432, the second gear 421, the fourth gear 431, and the sixth gear 441 increase sequentially. The first gear 411 drives the second gear 421 and the third gear 422 to move coaxially, the third gear 422 drives the fourth gear 431 and the fifth gear 432 to move coaxially, and the fifth gear 432 drives the sixth gear 441. This achieves multi-stage gear motion, resulting in good chain drive effect and stable performance. The first gear 411 drives the second gear 421 to rotate, thereby reducing the speed of the second gear 421. At the same time, the large tooth of the second gear 421 rotates coaxially with the third gear 422, and the small tooth of the third gear 422 also rotates slowly. The third gear 422 then meshes with the large tooth of the fourth gear 431, causing the large tooth to decelerate again, thus achieving multi-stage deceleration. Moreover, the fixed combination of the size of each gear can make full use of space, resulting in a small overall volume.

[0049] In this embodiment, the fixing base 1 includes a profile housing 11, a drive plate 12 fixed to the side of the profile housing 11 away from the gear transmission mechanism 4, and a rear cover plate 13 fixed to the drive plate 12 away from the drive mechanism 2; the drive mechanism 2 is located inside the profile housing 11 and fixed to the drive plate 12.

[0051] In this embodiment, the gearbox 3 and the fixed base 1 are fixedly connected by bolts 6, making it convenient to install the gearbox 3 and the fixed base 1.
