Description

Technical Field

[0001] This utility model relates to the field of Venetian blind technology, specifically to an ultra-short motor structure for driving Venetian blinds. Background Technology

[0002] Motorized Venetian blinds are frequently used in office spaces. They replace the manual pulling method of traditional blinds by using a DC motor to raise and lower the slats. Made of materials such as aluminum, wood, or PVC, the slats have an automatic tilting function, allowing for more precise adjustment of natural light levels and achieving optimal visual comfort. Common Venetian blinds are dual-axis, with the motor mounted in the center driving a winding mechanism. However, this requires larger blinds to accommodate the motor, and some single-axis motors also waste space. Furthermore, the way the power cord is wound in the motor design often occupies significant space during assembly, leading to wasted space. Therefore, improving existing motor structures and designing a new, ultra-compact motor structure to drive Venetian blinds to address these technical shortcomings and improve the overall practicality of the motor structure is particularly important. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-short motor structure for driving Venetian blinds, which solves the problem that the existing motor power cord winding method occupies a lot of space and causes waste during structural assembly.

The first mounting plate is connected to the fixing seat through the first screw.

[0007] As a preferred embodiment of this utility model, the brake has multiple sets of positioning grooves at one end near the outer shell, and two sets of positioning blocks are fixedly connected to the ends of both the outer shell and the fixed shell near the brake. Both the outer shell and the fixed shell are connected to the positioning grooves through the positioning blocks.

[0008] In a preferred embodiment of this utility model, the sleeve is connected to the brake via a second screw, and both the brake and the gearbox are installed inside the sleeve.

[0009] As a preferred embodiment of this utility model, the rear end of the gearbox is fixedly connected to multiple sets of fixing slots, and the end of the second mounting plate near the gearbox is fixedly connected to multiple sets of fixing blocks. The second mounting plate is connected to the fixing slots through the fixing blocks.

[0010] As a preferred embodiment of this utility model, the brake and gearbox are connected to each other by two sets of first buckles and two sets of first blocks. Two sets of second blocks are fixedly connected to the front end of the outer side of the fixed shell. The outer shell is connected to the two sets of second blocks by two sets of second buckles.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, through overall design, the motor structure solves the problem of large space occupation of traditional venetian blind motors by compact design. The outer shell, brake, and gearbox are precisely connected to the positioning block and positioning groove, and quick locking is achieved by buckle. The sleeve wraps the core components and is fixed by the second lateral screw, avoiding the increase of axial length. The power cord and antenna share the same connection groove, reducing the occupation of the opening. The lateral screw and hidden buckle design avoid axial extension, and the motor length is significantly shortened. By using buckle and screw cooperation and the narrowing process of steel pipe, the space generated by the screw hole seat required for the whole machine assembly is reduced.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-6 This utility model provides a technical solution:

[0024] An ultra-small motor structure for driving Venetian blinds includes an outer shell 1, a brake 2 at the front end of the outer shell 1, a gearbox 3 fixedly connected to the end of the brake 2 away from the outer shell 1, a motor 4 fixedly connected to the front end inside the outer shell 1, a PCBA board 5 fixedly connected to the rear end inside the outer shell 1, a fixing shell 6 on the outer side of the outer shell 1, the outer shell 1 and the outer side of the fixing shell 6 being connected by a sleeve 7, a first mounting plate 8 fixedly connected to the rear end of the outer shell 1, and a second mounting plate 9 at the front end of the gearbox 3.

[0025] Furthermore, the first mounting plate 8 is provided with a first screw 10 inside. A fixing seat 11 is fixedly connected to the rear end of the fixing shell 6 and outside the first screw 10. The first mounting plate 8 is connected to the fixing seat 11 through the first screw 10, so that the fixing shell 6 and the outer shell 1 are connected, and the fixing seat 11 is moved to the inside of the outer shell 1. The first screw 10 is threaded into the inside of the fixing seat 11 and is limited to the fixing shell 6, so that the fixing shell 6 can be limited to the first mounting plate 8, thereby installing the fixing shell 6 on the outside of the outer shell 1.

[0026] The brake 2 has multiple sets of positioning grooves 12 at one end near the outer shell 1. Both the outer shell 1 and the fixed shell 6 have two sets of positioning blocks 13 fixedly connected at one end near the brake 2. The outer shell 1 and the fixed shell 6 are connected to the positioning grooves 12 through the positioning blocks 13. By connecting the multiple sets of positioning blocks 13 to the multiple sets of positioning grooves 12, the outer shell 1 and the fixed shell 6 can be connected to the brake 2. When assembling the outer shell 1 and the fixed shell 6, the outer shell 1 and the fixed shell 6 can be assembled on the outside of the brake 2.

[0027] Secondly, the sleeve 7 is connected to the brake 2 by the second screw 14. Both the brake 2 and the gearbox 3 are installed inside the sleeve 7. The sleeve 7 is installed on the outside of the outer shell 1, the brake 2, the gearbox 3 and the fixed shell 6, so that they can be protected. The second screw 14 is connected to the brake 2, so that the position of the sleeve 7 can be fixed. The screw in the middle can prevent the internal parts from coming loose from the left and right sides, without increasing the length of the dimensions.

[0028] Furthermore, the rear end of the gearbox 3 is fixedly connected to multiple sets of fixing slots 15, and the end of the second mounting plate 9 near the gearbox 3 is fixedly connected to multiple sets of fixing blocks 16. The second mounting plate 9 is connected to the fixing slots 15 through the fixing blocks 16, and the fixing blocks 16 are moved into the inside of the fixing slots 15, so that the second mounting plate 9 can be moved into the inside of the gearbox 3, thereby installing the second mounting plate 9 inside the gearbox 3.

[0029] Furthermore, the brake 2 and gearbox 3 are interconnected via two sets of first latches 17 and two sets of first latch blocks 18. Two sets of second latch blocks 19 are fixedly connected to the front end of the outer side of the fixed housing 6. The outer housing 1 is connected to the two sets of second latch blocks 19 via two sets of second latches 20. Two sets of embedded latch blocks 21 are fixedly connected to the rear end of the outer side of the outer housing 1. The fixed housing 6 is connected to the embedded latch blocks 21 via a third latch 22, bringing the brake 2 and gearbox 3 into contact, thus interconnecting the two sets of first latches 17 and the two sets of first latch blocks 18. The positions of brake 2 and gearbox 3 are limited, so that brake 2 and gearbox 3 can be installed together. When the fixed shell 6 is installed with the outer shell 1, the design of the second locking block 19, the second buckle 20, the embedded locking block 21 and the third buckle 22 can increase the stability of the installation of the fixed shell 6 and the outer shell 1 and prevent loosening. The embedded locking block 21 is hidden in the buckle design, which not only ensures that the appearance is not affected, but also has a stronger locking ability. The first buckle 17 can support the motor 4.

[0030] Furthermore, a button 23 is provided at the rear end of the outer side of the outer casing 1, an antenna 24 is provided inside the outer casing 1, a power cord 25 is fixedly connected to the outer side of the motor 4, and two sets of guide plates 26 are fixedly connected to the rear end inside the outer casing 1. The two sets of guide plates 26 are respectively provided with connecting slots 27 between the outer casing 1 and the fixed shell 6. The power cord 25 extends to the outer side of the outer casing 1 through the connecting slots 27. By passing the power cord 25 through the two sets of connecting slots 27, the power cord 25 and the antenna 24 can come out from the same hole, and the path through the PCBA board 5 can make the power cord 25 firmly fixed inside, protecting the solder joints of the power cord 25 and preventing the solder joints from falling off and being damaged when pulled out from the outside. At the same time, it does not occupy space in the length direction of the motor.

[0031] In this embodiment, the specific implementation scenario is as follows: In actual use, the fixed shell 6 and the outer shell 1 are connected, causing the fixed seat 11 to move into the interior of the outer shell 1. The first screw 10 is threaded into the interior of the fixed seat 11, forming a limiting connection with the fixed shell 6, so that the fixed shell 6 can be limited to the first mounting plate 8, thereby installing the fixed shell 6 on the outside of the outer shell 1. Multiple sets of positioning blocks 13 are connected to multiple sets of positioning grooves 12, so that the outer shell 1 and the fixed shell 6 can be connected to the brake 2. During the assembly of the outer shell 1 and the fixed shell 6... The outer shell 1 and the fixed shell 6 can be assembled on the outside of the brake 2. The fixing block 16 is moved into the inside of the fixing groove 15, so that the second mounting plate 9 can be moved into the inside of the gearbox 3. The second mounting plate 9 is then installed inside the gearbox 3, bringing the brake 2 and the gearbox 3 into contact. This allows the two sets of first latches 17 and two sets of first latch blocks 18 to connect with each other, limiting the position of the brake 2 and the gearbox 3. This allows the brake 2 and the gearbox 3 to be installed together. When the fixed shell 6 is installed with the outer shell 1, the second latch block 19 and the second latch 20... The design of the embedded locking block 21 and the third latch 22 increases the stability of the installation of the fixing shell 6 and the outer shell 1, preventing loosening. The embedded locking block 21 is hidden in the internal latch design, ensuring that the appearance is not affected and providing stronger locking ability. The first latch 17 can support the motor 4, and the power cable 25 is passed through the two sets of connecting slots 27, so that the power cable 25 and the antenna 24 can come out from the same hole. The path through the PCBA board 5 can firmly secure the power cable 25, protecting the solder joints of the power cable 25. To prevent damage to the weld points caused by external pulling, and without occupying space along the length of the motor, the sleeve 7 is installed on the outside of the outer shell 1, brake 2, gearbox 3, and fixed shell 6, providing protection for them. The second screw 14 is connected to the brake 2 to fix the position of the sleeve 7. The middle screw prevents the internal parts from loosening from the left and right sides without increasing the length. Compared with the existing motor structure, this utility model improves the overall practicality of the motor structure through design.
