Description

Technical Field

[0001] This utility model belongs to the field of curtain equipment technology, specifically relating to a torque transmission structure between a motor and a transmission box. Background Technology

[0002] Electric curtains mainly consist of a motor, a transmission box, and a track. Among them, concealed electric curtains are becoming increasingly popular because they save space and do not disrupt the style of home decoration. Concealed electric curtains are installed by creating grooves in the ceiling or suspended ceiling where the curtains will be installed, and then embedding the curtain track and transmission box into these grooves. However, these concealed electric curtains still use relatively large motors. When the motor is installed parallel to the track, a large groove needs to be created in the ceiling or suspended ceiling. When the motor is installed vertically perpendicular to the curtain track, it is still exposed on the outside of the installation groove. This results in a less aesthetically pleasing appearance, a larger footprint, and a less compact structure, which to some extent hinders the popularization and promotion of concealed electric curtains.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1-6 As shown, a torque transmission structure between a motor and a transmission box includes a transmission box 1, a drive pulley 11 rotatably mounted inside the transmission box 1, and a drive box 2 connected to one end of the transmission box 1 and arranged adjacent to it in the same direction. The transmission box 1 and the drive box 2 are detachably connected and flush on their sides. The drive box 2 and the transmission box 1 are arranged adjacent to each other in the same direction and their shapes match to form an internally connected box, resulting in a high aesthetic appeal.

[0026] In this embodiment, a drive motor 3 is installed inside the drive housing 2, and a transmission seat 4 is provided at one end of the drive motor 3. The transmission seat 4 has a gear set 5 connected to the motor shaft of the drive motor 3. The drive pulley 11 is connected to a pulley gear 12, which meshes with a transmission gear 6 located outside the transmission seat 4 and connected to the gear set 5. That is, by placing the drive motor 3 inside the drive housing 2, the torque of the drive motor 3 is transmitted to the synchronous pulley inside the transmission housing 1 step by step through the gear set 5, the transmission gear 6, and the pulley gear 12. This results in a compact structure and a small footprint.

[0027] The transmission housing 1 has a pulley cavity 13, and the pulley cavity 13 is equipped with a vertically arranged pulley mounting shaft 14. The drive pulley 11 is rotatably mounted on the pulley mounting shaft 14 via a pulley bearing 15. The pulley gear 12 is coaxial and integrally formed on the upper end of the drive pulley 11. The end of the transmission housing 1 near the drive housing 2 has a transmission notch 16. The pulley gear 12 extends outward from the transmission notch 16 into the drive housing 2 and meshes with the transmission gear 6. By rotatably mounting the integrally connected pulley gear 12 and drive pulley 11 in the pulley cavity 13 via the pulley bearing 15, and simultaneously extending the pulley gear 12 into the drive housing 2 and meshing with the transmission gear 6, the transmission housing 11 achieves this configuration.

[0028] Furthermore, the gear set 5 here includes a large gear 51 rotatably disposed within the transmission base 4. The large gear 51 is connected to the motor shaft of the drive motor 3 via a worm gear transmission assembly, and the large gear 51 is connected to the transmission gear 6 disposed on the outer side of the upper end of the transmission base 4 via a one-way transmission assembly. Preferably, the worm gear transmission assembly here includes a transmission base opening 52 disposed at one end of the transmission base 4 near the drive motor 3. The motor shaft of the drive motor 3 passes through the transmission base opening 52, and a worm 53 is disposed on the motor shaft. A worm wheel 54 is disposed on one side of the worm 53 and meshes with it. A small gear 55 is coaxially connected to the lower end of the worm wheel 54 and meshes with the large gear 51. The one-way transmission assembly is a one-way clutch 56 disposed on the outer side of the upper end of the transmission base 4 and connected to the large gear 51. The one-way clutch 56 is connected to the transmission gear 6 in a one-way transmission, and a gear bearing 57 is disposed on the outer side of the lower end of the transmission gear 6.

[0029] The one-way clutch here uses a clutch similar to that in the existing patent CN101871493B. That is, the worm gear 53 drives the worm wheel 54 to rotate, thereby enabling the small gear 55 to drive the large gear 51 to rotate. The large gear 51 can drive the transmission gear 6 to rotate through the one-way clutch 56. Then, the transmission gear 6 drives the pulley gear 12 and the drive pulley 11 to rotate together. When the curtain needs to be pulled manually, when the trolley drives the synchronous belt to rotate, the drive pulley 11 can rotate and drive the pulley gear 12 and the transmission gear 6 to rotate together. However, due to the action of the one-way clutch 56, the large gear 51 here will not rotate with the transmission gear 6.

[0030] Furthermore, the drive housing 2 here is provided with a vertically arranged motor mounting plate 21. The drive motor 3 is located in the motor mounting cavity 22 on one side of the motor mounting plate 21, and one end of the drive motor 3 is fixedly mounted on one side of the motor mounting plate 21. The transmission seat 4 is set on the other side of the motor mounting plate 21 through the transmission seat mounting structure 7. Preferably, the transmission seat 4 is a split structure, and the transmission seat 4 is assembled from two upper and lower halves 41. The transmission seat mounting structure 7 here includes a snap-fit ​​fixing component set between the transmission seat 4 and the motor mounting plate 21, and a mounting fixing component set between the transmission seat 4 and the drive housing 2.

[0031] Preferably, the snap-fit ​​fixing assembly includes a snap-fit ​​body 71 disposed on the outer side of one end of the transmission seat 4, and a snap-fit ​​seat 72 disposed on one side of the motor mounting plate 21, the snap-fit ​​seat 72 having a snap-fit ​​groove 73 for engaging with the snap-fit ​​body 71; the mounting fixing assembly includes a mounting seat 74 disposed on the outer periphery of the transmission seat 4, the mounting seat 74 being connected to a positioning post 75 disposed within the drive housing 2 by mounting bolts. Clearly, the snap-fit ​​fixing assembly and the mounting fixing assembly ensure a secure connection between the transmission seat 4 and the motor mounting plate 21, while simultaneously ensuring that the transmission seat 4 is securely installed within the drive housing 2.

[0032] The principle of this embodiment is as follows: by embedding the drive motor 3 inside the drive housing 2, the drive housing 2 and the transmission housing 1 are arranged adjacent to each other in the same direction and their shapes match to form an internally connected housing. This improves the overall coordination and makes the entire transmission system more compact. When the curtains are opened or closed electrically, the motor shaft of the drive motor 3 drives the worm gear 53 to rotate, and the worm gear 53 drives the worm wheel 54 to rotate, thereby enabling the small gear 55 to drive the large gear 51 to rotate. The large gear 51 can drive the transmission gear 6 to rotate through the one-way clutch 56. Then, the transmission gear 6 drives the pulley gear 12 and the drive pulley 11 to rotate together. When the curtain needs to be pulled manually, the trolley drives the synchronous belt to rotate, and the drive pulley 11 can rotate, driving the pulley gear 12 and the transmission gear 6 to rotate together. However, due to the action of the one-way clutch 56, the large gear 51 will not rotate with the transmission gear 6, thus preventing the motor shaft from rotating.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
