Description
Technical Field
[0001] This utility model relates to the field of curtains, and in particular to a snap-fit installation and fixing structure for a curtain motor gearbox. Background Technology
[0002] With the development of science and technology, smart curtains are gradually entering thousands of households. Smart curtains mainly consist of a smart curtain motor, curtain track, and curtain fabric. The smart curtain motor mainly comprises a DC motor, gearbox, clutch, circuit board, and other components. The gearbox needs to be installed within a fixed structure. Currently, most manufacturers use screws to connect the gearbox to the fixed structure, resulting in a time-consuming, labor-intensive, and costly assembly process (due to the added screws and other parts). Furthermore, some designs use the gearbox gear ring as a load-bearing fixing component, which can cause gear ring deformation, affecting transmission efficiency and increasing noise.
[0003] Therefore, it is necessary to develop a snap-fit installation and fixing structure for the curtain motor gearbox to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to design a snap-fit installation and fixing structure for a curtain motor gearbox in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A snap-fit mounting structure for a curtain motor gearbox is used for mounting the gearbox. The mounting structure includes:
[0007] The fixed frame is formed into a barrel-shaped structure; a mounting hole is provided at the center of the bottom of the fixed frame; the gearbox is inserted into the fixed frame, and the bottom of the gearbox is placed on the bottom of the fixed frame; the rotating shaft of the curtain motor passes upward through the mounting hole and connects to the gearbox.
[0008] The mounting flange is installed on top of the mounting bracket; an annular support is formed on the inner side of the mounting flange, and multiple bosses are provided on the top of the annular support, with grooves formed between adjacent bosses; the mounting flange is installed in a fixed position.
[0009] Connecting ring; The connecting ring is set on the upper outer side wall of the gearbox; Multiple locking teeth are provided on the outer side wall of the connecting ring, and some of the locking teeth are set into multiple grooves for circumferential limiting of the gearbox;
[0010] At least two clips for axial positioning of the gearbox; at least two notches are provided on the inside of the mounting flange, each notch housing a clip, and at least two locking teeth engage with the clips.
[0011] The beneficial effects of this utility model are as follows:
[0012] In this application, a groove is used to engage with a portion of the locking teeth to prevent the gearbox from rotating circumferentially, and a buckle is used to engage with another portion of the locking teeth to limit the gearbox axially, thereby fixing the gearbox and making the installation efficiency of the gearbox higher; and the gearbox is placed in a barrel-shaped fixing frame, which can reduce the noise generated by the gearbox to a certain extent.

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] like Figure 1-5 As shown, a snap-fit mounting structure for a curtain motor gearbox is used for mounting the gearbox 4. The mounting structure includes:
[0027] Fixed frame 2; Fixed frame 2 is formed into a barrel-shaped structure; A mounting hole 9 is provided at the center of the bottom of the fixed frame 2; The gearbox 4 is inserted into the fixed frame 2, and the bottom of the gearbox 4 is placed on the bottom of the fixed frame 2; The rotating shaft of the curtain motor 1 passes through the mounting hole 9 upward and is connected to the gearbox 4.
[0028] Mounting flange 3; Mounting flange 3 is installed on the top of the fixing frame 2; An annular bearing platform 10 is formed on the inner side of mounting flange 3, and multiple bosses 11 are provided on the top of the annular bearing platform 10, with grooves 7 formed between adjacent bosses 11; Mounting flange 3 is fixedly installed.
[0029] Connecting ring 5; Connecting ring 5 is set on the upper outer side wall of gearbox 4; Multiple locking teeth 6 are provided on the outer side wall of connecting ring 5, and some locking teeth 6 are set into multiple grooves 7 for circumferential limiting of gearbox 4.
[0030] Three clips 8 are used for axial positioning of the gearbox 4; three notches 12 are provided on the inner side of the mounting flange 3, and a clip 8 is installed in each notch 12, and three locking teeth 6 are engaged with the clips 8.
[0031] In some embodiments, such as Figure 1 and 2 As shown, the mounting flange 3 has two mounting holes 9. The mounting flange 3 is fixedly installed on the other structural components after the bolts pass through the mounting holes 9.
[0032] In some embodiments, such as Figure 5 As shown, a mounting base 13 is installed at the bottom of the mounting bracket 2, and the bottom of the gearbox 4 is placed on the mounting base 13. It should be noted that when the locking teeth 6 and the buckles 8 are engaged, some of the locking teeth 6 simultaneously engage with multiple grooves 7, and the bottom of the mounting bracket 2 is placed on the mounting base 13.
[0033] In some embodiments, such as Figure 2 As shown, at least two buckles 8 are evenly distributed around the axis of the fixing frame 2.
[0034] In some embodiments, such as Figure 2 As shown, multiple locking teeth 6 are evenly distributed around the axis of the fixing frame 2.
[0035] In this application, the gearbox 4 is installed inside the fixing frame 2. The lower end of the fixing frame 2 is connected to the curtain motor 1 by screws (the bottom of the fixing frame 2 has multiple countersunk holes, and the bolts pass through the countersunk holes and are screwed into the screw holes on the curtain motor 1 to complete the connection and installation). Multiple teeth 6 and multiple grooves 7 on the connecting ring 5 cooperate to prevent the gearbox 4 from rotating circumferentially. At the same time, the gearbox 4 is axially limited by the engagement of the buckle 8 with the teeth 6, thereby achieving the purpose of fixing the gearbox 4. At the same time, since the buckle 8 is relatively shallow, if there is a problem with the gearbox 4, it needs to be disassembled. The gearbox 4 can be removed by slightly prying up the buckle 8 with a flathead screwdriver, which is convenient for repairing the gearbox 4. Also, because of the use of the buckle 8, a click sound can be heard when the gearbox 4 is installed in place, which makes it easy for the operator to judge whether the installation is in place.
[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
