Description

Technical Field

[0001] This utility model relates to the field of electric curtain accessories, and in particular to a motor installation and drive structure for opening and closing curtains. Background Technology

[0002] Currently, the drive structure of most curtain opening and closing mechanisms consists of a housing, a rotary drive mechanism, and a transmission box for driving a synchronous belt (the curtain is connected to the synchronous belt, and the synchronous belt is connected to the transmission component in the transmission box). The rotary drive mechanism is located in the housing, with its rotary drive end extending out of the housing. The housing is detachably mounted on the transmission box, and the rotary drive end of the rotary drive mechanism is connected to the transmission component in the transmission box. Power is output through the rotary drive mechanism, which sequentially drives the transmission component in the transmission box and the synchronous belt, thereby causing the curtain to open and close.

[0003] While this design can meet the driving requirements of small curtains, the increasing size of existing curtains means that the reaction force that the curtain's driving structure needs to withstand also increases with the size of the curtain. In other words, the reaction force on the housing increases with the size of the curtain. However, existing housings still use a conventional assembly structure, specifically two outer shells fastened together with screws. Although such housings can withstand a certain amount of reaction force, they are very prone to deformation and damage as the reaction force increases, which seriously affects the performance and lifespan of the driving structure.

[0004] Therefore, it is essential to design a highly stable motor mounting and drive structure for opening and closing curtains to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a high-stability curtain motor mounting and driving structure. This high-stability curtain motor mounting and driving structure not only ensures a relatively simple overall structure, but also effectively improves the performance against reaction forces. It can be used for a long time under greater reaction forces without deformation or damage, and it has very high stability and reliability, as well as better performance and a longer service life.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A high-stability curtain motor mounting and driving structure includes an upper shell, a lower shell, and a rotary drive mechanism. The upper shell and the lower shell are fastened together, forming an installation cavity between them. The rotary drive mechanism is disposed in the installation cavity. The structure is characterized by further including a sleeve shell with one open side. One end of the upper shell has a locking notch, through which the power output end of the rotary drive mechanism passes. The sleeve shell is simultaneously fitted onto the other end of the upper shell and the corresponding end of the lower shell.

[0008] Preferably, the inner walls around the ports of the housing are provided with fastening protrusions, and fastening grooves are provided on the outer walls of the upper shell, the lower shell, and the outer walls at the fastening points of the upper and lower shells. The number of fastening grooves is equal to the number of fastening protrusions, and each fastening protrusion is fastened into each fastening groove.

[0009] Preferably, the end face of the fastening protrusion facing the opening of the housing is a guide slope that slopes inward toward the housing.

[0010] Preferably, the high-stability curtain motor mounting drive structure further includes a transmission box. The mounting notch is longitudinally opened through the upper shell. At least one vertical positioning strip with an L-shaped cross-section is provided on the vertical wall of the mounting notch. A hook assembly that can be pressed and released is provided on the lower wall of the mounting notch. One end of the transmission box is embedded in the mounting notch and is fitted onto the vertical positioning strip. The transmission box is also hung by the hook assembly. The power output end of the rotary drive mechanism is vertically placed on the lower wall of the mounting notch and is driven and connected to the power output end of the rotary drive mechanism.

[0011] Preferably, the hook assembly includes a hook block and at least one spring. A clearance notch is provided on the lower edge of the mounting notch away from its vertical opening wall. The hook block is laterally slidable in the mounting cavity. The spring is laterally arranged in the mounting cavity and acts elastically on the hook block, also pushing the hook block away from the vertical opening wall of the mounting notch. The hook end of the hook block extends from the clearance notch into the mounting notch, and the hook end is positioned away from the vertical opening wall of the mounting notch. The hook end is hooked onto the transmission box. The hook block has a pressing part placed in the clearance notch.

[0012] Preferably, at least one hanging hole is provided on the front and rear top surfaces of the transmission box, and a detachable curtain hook is hung on one of the hanging holes.

[0013] Preferably, the curtain hook includes a vertical strip, a hanging ring, and a hook body. The hook body and the hanging ring are respectively disposed on the upper and lower ends of the vertical strip. The hook body includes a hanging piece and a hook piece. One end of the hanging piece is connected to the upper end of the vertical strip, and the hook piece is disposed on the bottom surface of the other end of the hanging piece, so that the hanging piece gradually approaches the vertical strip from top to bottom. The hanging piece overlaps the top surface of the transmission box, and the hook piece is inserted into the hanging hole.

[0014] Preferably, a button switch is provided on the bottom surface of the end of the lower shell that is not fitted with the outer shell.

[0015] Preferably, a power supply interface is provided on the bottom surface of the end of the lower shell that is fitted by the sleeve shell, and a limiting hole is provided on the outer wall of the sleeve shell that extends through the power supply interface.

[0016] The beneficial effects of this utility model are as follows: In this high-stability curtain motor installation and drive structure, a sleeve is simultaneously fitted onto the other end of the upper shell and the corresponding end of the lower shell. This sleeve effectively enhances the fastening strength of the upper and lower shells. This structure not only ensures a relatively simple overall structure but also significantly improves the anti-reaction force performance of the upper and lower shells. It can be used for a long time under greater forces without deformation or damage, exhibiting very high stability and reliability, resulting in better performance and a longer service life. A locking notch is provided, and the power output end of the rotary drive mechanism is placed within it. This notch enables locking and positioning, which not only improves the accuracy and stability of the combination with the transmission box but also facilitates a more stable and reliable transmission connection between the power output end of the rotary drive mechanism and the transmission box, thus contributing to improved transmission stability and accuracy.

[0026] like Figures 1 to 6 As shown, the high-stability curtain motor installation and drive structure of this utility model includes an upper shell 1, a lower shell 2, and a rotary drive mechanism 3. The upper shell 1 and the lower shell 2 are fastened together, and an installation cavity 10 is formed between the upper shell 1 and the lower shell 2. The rotary drive mechanism 3 is disposed in the installation cavity 10. To achieve the purpose of this utility model, it also includes a sleeve shell 4 with one side open. A snap-fit ​​notch 20 is opened on one of the left or right ends of the upper shell 1, and the power output end of the rotary drive mechanism 3 passes through the snap-fit ​​notch 20. The sleeve shell 4 is simultaneously fitted onto the other end of the upper shell 1 and the corresponding end of the lower shell 2.

[0027] In this high-stability curtain motor installation drive structure, a sleeve shell 4 is simultaneously fitted onto the other end of the upper shell 1 and the corresponding end of the lower shell 2. This sleeve shell 4 effectively enhances the fastening strength of the upper shell 1 and the lower shell 2. This structure not only ensures a relatively simple overall structure, but also significantly improves the resistance of the upper shell 1 and the lower shell 2 to reaction forces. It can be used for a long time under greater forces without deformation or damage, and it has very high stability and reliability, resulting in better performance and a longer service life.

[0028] A mounting notch 20 is made, and the power output end of the rotary drive mechanism 3 is placed in the mounting notch 20. This can achieve the purpose of mounting and positioning using the mounting notch 20. This not only helps to improve the accuracy and stability of the combination with the transmission box, but also helps to achieve a more stable and reliable transmission connection between the power output end of the rotary drive mechanism 3 and the transmission box. This helps to improve the stability and accuracy of the transmission.

[0029] The upper shell 1 and the lower shell 2 are fastened together and locked with screws; the set shell 4 not only helps to enhance the assembly strength, but also improves the quality.

[0030] like Figures 1 to 6As shown, the inner walls around the ports of the housing 4 are provided with fastening protrusions 41. Fastening grooves 30 are respectively formed on the outer walls of the upper shell 1, the lower shell 2, and the outer walls at the fastening points of the upper shell 1 and lower shell 2. The number of fastening grooves 30 is equal to the number of fastening protrusions 41, and each fastening protrusion 41 is fastened into its respective fastening groove 30. This effectively enhances the accuracy and reliability of the housing 4 assembly, enabling the housing 4 to perform a more stable and reliable limiting and reinforcing function. Furthermore, it allows the upper shell 1 and lower shell 2 to exhibit a more stable and reliable resistance to reaction forces, which helps to further improve the reliability and applicability of the high-stability curtain motor installation drive structure.

[0031] like Figure 5 As shown, the end face of the fastening protrusion 41 facing the opening of the housing 4 is a guide slope 411 that slopes inward toward the housing 4. This helps to improve the smoothness and convenience of assembling the housing 4, thereby improving the convenience and efficiency of assembly.

[0032] like Figures 1 to 7 As shown, the high-stability curtain motor mounting drive structure also includes a transmission box 5. The mounting notch 20 extends longitudinally through the upper shell 1. At least one L-shaped vertical positioning strip 201 is provided on the vertical wall of the mounting notch 20. A hook assembly 6, capable of being pressed and released, is provided on the lower wall of the mounting notch 20. One end of the transmission box 5 is embedded in the mounting notch 20, and the transmission box 5 is secured to the vertical positioning strip 201 and hung by the hook assembly 6. The power output end of the rotary drive mechanism 3 is vertically positioned on the lower wall of the mounting notch 20, and the transmission box 5 is driven and connected to the power output end of the rotary drive mechanism 3. This facilitates the quick, accurate, and stable assembly of the transmission box 5 and the upper shell 1, ensuring accurate and stable transmission connection between the transmission box 5 and the rotary drive mechanism 3, thereby further improving reliability and applicability.

[0033] Both the transmission box 5 and the rotary drive mechanism 3 adopt existing structures, and the transmission connection between them also adopts existing structures, which can meet the needs of actual manufacturing and use.

[0034] like Figure 3 , Figure 5 , Figure 6 and Figure 9As shown, the hook assembly 6 includes a hook block 61 and at least one spring 62. The mounting notch 20 has a clearance notch 202 on its lower edge away from its vertical opening wall. The hook block 61 is slidably disposed in the mounting cavity 10. The spring 62 is arranged laterally in the mounting cavity 10 and acts elastically on the hook block 61. The spring 62 can also push the hook block 61 away from the vertical opening wall of the mounting notch 20. The hook end 611 of the hook block 61 passes through the clearance notch 202 into the mounting notch 20. The hook end 611 is positioned away from the vertical opening wall of the mounting notch 20. The hook end 611 is hooked onto the transmission box 5. The hook block 61 has a pressing part 612 placed in the clearance notch 202. The pressing part 612 is designed for manual pressing, which disengages the hook assembly 6 from the transmission box 5, facilitating quick disassembly. The spring 62 not only provides automatic, accurate, and stable reset but also ensures a stable and reliable hooking effect for the hook block 61, thus providing stable and reliable positioning for the transmission box 5 and improving assembly reliability. This hook assembly 6 not only provides accurate and stable hooking but also facilitates easy assembly and disassembly, further enhancing reliability and applicability.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, at least one hanging hole 51 is provided on the front and rear top surfaces of the transmission box 5, and a detachable curtain hook 7 is hung on one of the hanging holes 51. The curtain hook 7 can facilitate the quick, accurate and stable positioning of the curtain end; the hanging holes 51 at the front and rear can be interchanged to meet the installation requirements, thus facilitating different usage needs and further improving applicability.

[0036] like Figure 3 and Figure 8 As shown, the curtain hook 7 includes a vertical strip 71, a hanging ring portion 72, and a hook body portion 73. The hook body portion 73 and the hanging ring portion 72 are respectively disposed on the upper and lower ends of the vertical strip 71. The hook body portion 73 includes a hanging piece portion 731 and a hook piece portion 732. One end of the hanging piece portion 731 is connected to the upper end of the vertical strip 71, and the hook piece portion 732 is disposed on the bottom surface of the other end of the hanging piece portion 731, so that the hanging piece portion 731 gradually approaches the vertical strip 71 from top to bottom. The hanging piece portion 731 overlaps the top surface of the transmission box 5, and the hook piece portion 732 is inserted into the hanging hole 51. Such a curtain hook 7 is very simple and reliable, which not only facilitates extremely stable and reliable installation and positioning, but also helps to ensure that the curtain installation is very stable and reliable, thereby helping to further improve reliability and applicability.

[0037] like Figure 2 As shown, a push-button switch 8 is provided on the bottom surface of the end of the lower shell 2 that is not fitted with the outer shell 4. This not only prevents the outer shell 4 from affecting the switch operation, but also makes the switch very convenient, thereby helping to further improve its applicability.

[0038] like Figure 4 and Figure 6 As shown, a power supply interface 9 is provided on the bottom surface of the end of the lower shell 2 that is fitted by the sleeve shell 4. A limiting hole 42 is provided on the outer wall of the sleeve shell 4, which extends through the power supply interface 9. This not only enhances the structural strength of the power supply interface 9 using the sleeve shell 4, but also uses the limiting hole 42 to limit the connection, so that the power supply line can be connected to the power supply interface 9 more stably and accurately, thereby helping to further improve reliability and applicability.
