Description

Technical Field

[0001] The utility model relates to the field of curtain accessories, in particular to a curtain motor terminal structure. Background Art

[0002] The patent document with Chinese authorization publication number CN220342168U discloses a technical solution entitled "A Curtain Motor Device" (the technical solution disclosed in the patent document was designed by the applicant and a patent application was filed). The technical solution includes the following technical features: it includes a motor body and a transmission box, wherein a convex shell portion is provided on the motor body, and the power output end of the motor body is placed on the convex shell portion; a positioning groove is provided on the transmission box, and the power input end of the transmission box is placed in the positioning groove; the convex shell portion can be detachably embedded in the positioning groove, and the power input end of the transmission box is driven and connected to the power output end of the motor body; the convex shell portion is rotatably snapped into the positioning groove; the motor body is provided with an elastic telescopic part arranged side by side with the convex shell portion, and the elastic telescopic part is inserted into the transmission box.

[0003] To facilitate the installation of the convex shell and its rotation within the positioning slot, a relatively large gap is typically created between the convex shell and the positioning slot during actual manufacturing. Furthermore, the elastic telescopic member is limited in position only by inserting the transmission box. Consequently, the stability of the assembly between the motor body and the transmission box is limited, making it prone to movement of the motor body relative to the transmission box. Since curtains are generally heavy, the motor body must generate a significant force to open and close the curtains during use. This results in a significant force between the motor body and the transmission box, which can easily cause significant vibrations in the motor body. Furthermore, the relative movement of the motor body relative to the transmission box not only generates significant noise but also affects the stability of power transmission between the motor body and the transmission box, thereby impacting the performance and service life of the curtain motor.

[0004] Therefore, it is very necessary to design a curtain motor end structure to solve the above technical problems. Utility Model Content

[0027] like Figures 1 to 3 As shown, the curtain motor terminal structure described in the present invention includes a terminal body 1, an elastic plug-in mechanism 2 is provided on the terminal body 1, and a nested connecting portion 3 is also provided on the terminal body 1.

[0028] In the curtain motor terminal structure, by respectively arranging an elastic plug-in mechanism 2 and a nested connecting portion 3 on the terminal body 1, the elastic plug-in mechanism 2 can be utilized to realize the requirement of elastic plug-in of the motor body, and the nested connecting portion 3 can be nested with the motor body; in this way, the elastic plug-in of the elastic plug-in mechanism 2 can be utilized to play an elastic limiting and reinforcing role, which can help improve the stability of the assembly between the motor body and the terminal body 1, and avoid the motor body from moving relative to the terminal body 1. This not only helps to reduce noise, but also makes power transmission very accurate and stable, thereby helping to improve the performance and service life of the curtain motor.

[0029] like Figure 3 and Figure 4 As shown, the elastic plug-and-hang mechanism 2 includes a plug-and-hang hook body 21 and an elastic member 22. The plug-and-hang hook body 21 is horizontally slidably mounted on the terminal body 1. The elastic member 22 is mounted on the terminal body 1 and elastically acts on the plug-and-hang hook body 21. This elastic plug-and-hang mechanism 2 is very simple and reliable, which not only facilitates manufacturing but also provides a very stable and reliable elastic plug-and-hang effect, thereby helping to further improve the reliability and applicability of the curtain motor terminal structure.

[0030] like Figures 3 to 6 As shown, the hook body 21 includes a sliding portion 211 and at least one hook 212. A horizontally extending guide slot 11 is defined on the terminal body 1. The sliding portion 211 is slidably mounted within the guide slot 11. The hook 212 is disposed on the sliding portion 211. The elastic member 22 elastically acts on the sliding portion 211 and / or the hook 212. This not only improves the stability and reliability of the installation and positioning of the hook body 21, but also enhances the smooth sliding of the hook body 21, thereby further enhancing the reliability of the curtain motor terminal structure.

[0031] like Figures 1 to 6As shown, the guide slot 11 is formed within the terminal body 1, the elastic member 22 is located within the terminal body 1, and the sliding portion 211 is provided with at least one toggle portion 213, which is positioned outside the terminal body 1. The hook 212 is also positioned outside the terminal body 1. This not only shields and protects the sliding portion 211 and the elastic member 22, but also prevents them from pinching your hands. Furthermore, the interior of the terminal body 1 can be used to further limit the sliding portion 211 and the elastic member 22. This not only facilitates a more stable and reliable limiting and guiding function, but also improves safety and performance in use.

[0032] like Figures 1 to 6 As shown, there are two plug hooks 212, which are arranged side by side on the sliding portion 211 and extend below the end body 1. There are two toggle parts 213, which are respectively arranged on the front and rear ends of the sliding portion 211 and extend to the front and rear outer walls of the end body 1. The guide slot 11 is a transverse guide slot. The elastic member 22 is a spring arranged transversely within the end body 1, with the two ends of the elastic member 22 elastically pressing against the end body 1 and the middle portion of the sliding portion 211. This not only helps to improve the stability and accuracy of the installation and positioning of the elastic plug-in mechanism 2, but also helps to improve the accuracy and stability of the sliding of the elastic plug-in mechanism 2, and enables the elastic plug-in mechanism 2 to achieve a more stable and reliable plug-in effect. In addition, this also facilitates the toggle of the elastic plug-in mechanism 2, thereby improving the convenience and stability of use.

[0033] like Figure 6 As shown, in actual manufacturing, each hook 212 can be mounted on the same metal sheet 214, and each hook 212 and the metal sheet 214 can be formed into an integral metal structure (e.g., stainless steel). The sliding portion 211 and the toggle portion 213 can be formed into an integral plastic component, and the metal sheet 214 can be embedded in the sliding portion 211. This not only reduces manufacturing costs but also improves the structural strength and durability of the hook 212, thereby further enhancing the reliability and applicability of the curtain motor terminal structure.

[0034] like Figure 6 As shown, the metal sheet 214 can not only be clamped and positioned by the inner wall of the end body 1 and the sliding part 211, but also the metal sheet 214 and the sliding part 211 can be bonded and fixed together, and the sliding part 211 can be injection molded on the metal sheet 214. In this way, the sliding part 211 can stably drive the metal sheet 214 to slide, thereby stably driving the plug hook 212 to slide, and thus can well meet the needs of actual use.

[0035] like Figures 1 to 3 As shown, the terminal body 1 includes a housing 12 and a drive wheel 13. The drive wheel 13 is rotatably disposed within the housing 12. A limit slot 121 is provided on the outer wall of the housing 12. A spline-shaped transmission shaft 131 is provided on the end face of the drive wheel 13, and the transmission shaft 131 is inserted into the limit slot 121. A clearance hole 122 is provided on the side wall of the housing 12. The limit slot 121 can be embedded in the insertion position of the power output shaft on the motor body. The use of the spline-shaped transmission shaft 131 can achieve a stable power transmission effect using the spline structure, thereby achieving a more stable and reliable connection between the motor body and the curtain motor terminal structure. The provision of the clearance hole 122 can facilitate the insertion of the traction belt, thereby helping to further improve the reliability and applicability of the curtain motor terminal structure.

[0036] like Figure 10 As shown, a transmission groove 102 that matches the transmission shaft 131 is formed on the end surface of the power output shaft 101 of the motor body 10. The power output shaft 101 is inserted into the motor body 10 with an outwardly protruding convex ring portion 103. During installation, the convex ring portion 103 is embedded in the limiting groove 121, and the transmission groove 102 is fitted onto the transmission shaft 131, thus meeting the power transmission requirements.

[0037] like Figure 3 As shown, the driving wheel 13 is a toothed pulley, and the clearance hole 122 is for the traction toothed belt to pass through and out, so as to meet the demand of driving the curtain through the engagement of the traction toothed belt and the driving wheel 13. This part of the driving structure directly adopts the existing structure, which can meet the actual manufacturing and use requirements.

[0038] like Figure 1 and Figure 3 As shown, the housing 12 includes a bottom-opening housing 123 and a cover 124. The drive wheel 13 and the elastic plug-and-hang mechanism 2 are both disposed within the housing 123. The cover 124 covers the opening of the housing 123, allowing the plug-and-hang portion of the elastic plug-and-hang mechanism 2 to protrude outside the cover 124. The nested connecting portion 3 is disposed on the bottom surface of the cover 124, and the clearance hole 122 is formed in the side wall of the housing 123. This enables the housing 12 to have a simple and reliable structure, which not only facilitates the manufacture of the housing 12 but also facilitates the installation of related components, thereby further improving the applicability of the curtain motor terminal structure.

[0039] like Figures 1 to 3As shown, a mounting notch 125 is formed on the lower wall of the clearance hole 122 and extends through the bottom surface of the housing 123. A clamping mechanism 4 for clamping the curtain rail is mounted in the mounting notch 125. The provision of mounting notch 125 not only facilitates the installation and adjustment of the clamping mechanism 4 but also allows for a better fit with the curtain rail. The clamping mechanism 4 facilitates a stable connection between the curtain motor terminal structure and the curtain rail, thereby further improving the applicability of the curtain motor terminal structure.

[0040] like Figures 1 to 3 、 Figure 7 and Figure 8 As shown, the bottom surface of the housing 123 is provided with a positioning groove 127 formed by a raised ring 126. The mounting notch 125 extends through the positioning groove 127. The clamping mechanism 4 includes a positioning block 41, a clamping block 42, an arched block 43, and a locking screw 44. The positioning block 41 is embedded in the positioning groove 127. The clamping block 42 is arranged in the clearance hole 122. A clamping gap 45 is reserved between the clamping block 42 and the lower wall of the clearance hole 122. The arched block 43 is arranged on the top surface of the clamping block 42, with both ends of the arched block 43 pressing against the top surface of the clamping block 42. The threaded end of the locking screw 44 passes upward through the positioning block 41, the mounting notch 125, and the clamping block 42, and then is screwed onto the middle portion of the arched block 43. This clamping mechanism 4 can provide a very stable and reliable clamping effect on the curtain rail, thereby further improving the applicability of the curtain motor terminal structure. The clearance hole 122 can be used for inserting a curtain rail (not shown in the figure, which adopts the existing structure). Since there is also a gap on the bottom surface of the curtain rail, it just matches the clamping mechanism 4, thereby meeting the demand for stably clamping the curtain rail.

[0041] like Figures 1 to 3 、 Figure 7 and Figure 8 As shown, the clamping block 42 has reinforcing protrusions 421 on its upper and lower surfaces at the end facing the opening of the clearance hole 122. The positioning block 41 has upwardly projecting tabs 411 at both the end near the opening of the clearance hole 122 and the end away from the opening of the clearance hole 122. The two tabs 411 pass through the mounting notch 125 and are then placed in the clearance hole 122. Furthermore, the tab 411 near the opening of the clearance hole 122 is inserted into the clamping block 42, while the tab 411 away from the opening of the clearance hole 122 is positioned to the side of the clamping block 42 away from the opening of the clearance hole 122. This provides a more stable and reliable structure for the clamping mechanism 4, thereby further improving the reliability of the curtain motor terminal structure.

[0042] like Figure 1As shown, the nesting connection portion 3 is a boss portion or a groove portion (not shown). Such a nesting connection portion 3 is very simple and reliable, which not only facilitates manufacturing but also facilitates a reliable nesting connection. When the nesting connection portion 3 is a boss portion or a groove portion, a matching groove or boss portion is correspondingly formed on the motor body to meet the nesting connection requirements.

[0043] like Figure 1 、 Figure 9 and Figure 10 As shown, in actual use, the curtain motor end structure is used in conjunction with the motor body 10, and the top surface of the motor body 10 is provided with plug-in holes 104 whose number is equal to the plug-in hooks 212 and whose positions correspond one to one. The top surface of the motor body 10 is provided with a positioning groove 105 for embedding the convex column part, and the top surface of the motor body 10 is provided with a makeshift groove 106 corresponding to the position of the convex ring 126. When installing the motor body 10, the installer first applies manual pressure to the elastic plug-in mechanism 2 to maintain the plug hook 212 in the unlocked position. The installer then aligns the plug-in hole 104, positioning groove 105, and clearance groove 106 on the motor body 10 with the plug hook 212, the column portion, and the convex ring portion 103, respectively. The plug-in hole 104 covers the plug-in hook 212, the positioning groove 105 fits over the column portion, and the clearance groove 106 covers the convex ring portion 103. The installer then releases the force exerted on the elastic plug-in mechanism 2. The elastic force of the elastic member 22 then pushes the plug hook 212 into the plug-in hole 104, while also achieving an elastic compressive force. This ensures a highly stable assembly of the curtain motor end structure and the motor body 10, preventing relative movement between the curtain motor end structure and the motor body 10. This not only reduces noise but also ensures very stable power transmission, thereby improving the performance and service life of the curtain motor.
