In one embodiment of the present invention, referring to fig. 1 and 2, a hitch mechanism 300 is provided for use in a window covering opener.

Referring to fig. 1 and 2, the hooking mechanism 300 includes a connection base 350, a bracket 310, a moving assembly 320, and a loading plate 400. The first end of the bracket 310 is inserted into the connecting base 350, the second end of the bracket 310 extends out of the connecting base 350, and the moving component 320 is mounted at the second end of the bracket 310 and is used for movably hanging on the curtain guide 10.

Referring to fig. 1 and 2, the carrier plate 400 is used to carry the curtain suspension ring 20. The supporting plate 400 is elongated, a first end of the supporting plate 400 is connected to a second end of the bracket 310, and the supporting plate 400 is parallel to the moving direction of the moving assembly 320 and is adjacent to the guide 10 when being mounted. The second end of the loading plate 400 is provided with a first inclined surface 420 and a convex portion 430 in sequence from the outside to the inside.

Referring to fig. 1 and 2, when the window covering is closed, the bearing plate 400 drives the plurality of hanging rings 20 located on the guide 10 to sequentially move along the first inclined surface 420 and pass through the protruding portion 430 to be closed and arranged on the bearing plate 400; when the window covering is unfolded, the carrying board 400 drives the plurality of hanging rings 20 thereon to sequentially pass over the protruding portion 430 and move along the first inclined surface 420 to be dispersedly arranged on the guide 10.

Specifically, compared with the prior art, the hanging mechanism provided by the embodiment of the invention has one of the following technical effects:

the hanging mechanism 300 is used in a curtain opener, and when the curtain opener is operated, the main body 200 of the curtain opener drives the moving component 320 and the bearing plate 400 to move along the curtain guide 10.

When the window curtain is furled, the bearing plate 400 moves along the guide 10, the first inclined surface 420 of the bearing plate 400 is inserted into the inner hole of the hanging ring 20, and the hanging ring 20 is driven to move along the first inclined surface 420 and move to the bearing plate 400 over the convex part 430 under the continuous movement of the bearing plate 400, so that the plurality of hanging rings 20 on the guide 10 are sequentially furled on the bearing plate 400 in the process that the bearing plate 400 moves along the guide 10, thereby furling the window curtain; as can be seen from the above, in the process of drawing the curtain, the bearing plate 400 drives the hanging ring 20 to move onto the bearing plate 400 and bear the hanging ring 20 and the curtain to move, so as to reduce the sliding friction between the hanging ring 20 and the guide 10, so that the hanging mechanism 300 drives the hanging ring 20 and the curtain to move smoothly, and the curtain moves smoothly when being drawn.

When the curtain is unfolded, the plurality of hanging rings 20 are folded and arranged on the bearing plate 400, and one end of the curtain close to the end part of the guide 10 is fixed on the guide 10; the carrying board 400 drives the plurality of hanging rings 20 to move along the guide 10, and when each hanging ring 20 moves to the maximum or near the maximum stroke along the carrying board 400, the plurality of hanging rings 20 sequentially cross the convex portion 430 and move along the first inclined surface 420 to slide on the guide 10, so that the plurality of hanging rings 20 on the carrying board 400 are dispersedly arranged on the guide 10 during the movement of the carrying board 400 along the guide 10, thereby realizing the unfolding of the curtain; as can be seen from the above, in the process of unfolding the curtain, the bearing plate 400 bears the movement of the hanging ring 20 and slides on the guide 10 when the hanging ring 20 moves to the maximum or close to the maximum stroke, so as to reduce the sliding friction between the hanging ring 20 and the guide 10, so that the hanging mechanism 300 drives the hanging ring 20 and the curtain to move smoothly, and the curtain moves smoothly when being unfolded.

In the prior art, when the curtain is unfolded, the main machine 200 pushes the hanging ring 20 to move, and because the hanging ring 20 is easy to incline, the sliding friction force generated between the hanging ring 20 and the guide 10 is greater than the thrust force of the main machine, so that the hanging ring 20 cannot move to the maximum stroke, and the curtain is not completely unfolded. It can be understood that, in this embodiment, the supporting board 400 drives the hanging ring 20 to move along with the supporting board 400, and the above-mentioned protruding portion 430 is provided, the protruding portion 430 has a certain blocking effect on the hanging ring 20, so that the hanging ring 20 will pass over the protruding portion 430 and slide down on the guiding element 10 when moving to the maximum or near the maximum stroke, and the hanging ring 430 moves so that the curtain at the section corresponding to the hanging ring 20 is also in the unfolded state, and the above-mentioned protruding portion 430 can prevent the hanging ring 20 from falling off from the supporting board 400 when not moving to the maximum or near the maximum stroke along with the supporting board 400, and the curtain at the section corresponding to the hanging ring 20 is in the unfolded or partially unfolded state, and the hanging ring 20 will slide along the guiding element 10 under the pulling of the main machine of the curtain opener so as to.

In summary, in the process of driving the hanging ring 20 to move by the hanging mechanism 300 of the present invention, not only the sliding friction between the hanging ring 20 and the guide 10 is reduced, but also the power required by the main machine 200 of the curtain opening and closing device to drive the curtain to fold or unfold is reduced, so that the energy consumption of the main machine 200 can be reduced, which is beneficial to energy saving.

Further, referring to fig. 1, 2 and 3, the opposite sides of the protrusion 430 are respectively provided with a second inclined surface 431 and a third inclined surface 432, and the lower end of the second inclined surface 431 is connected to the upper end of the first inclined surface 420. The first inclined surface 420 and the second inclined surface 431 play a guiding role, and under the driving of the bearing plate 400, the hanging ring 20 on the guide 10 easily moves along the first inclined surface 420 and the second inclined surface 431 and moves onto the bearing plate 400 over the convex part 430, so that the resistance is small, the movement is smooth, and the locking is avoided.

Similarly, referring to fig. 1, 2 and 3, the third inclined surface 432 plays a guiding role, and under the driving of the bearing plate 400, the lifting ring 20 on the bearing plate 400 easily moves along the third inclined surface 432 to get over the protrusion 430 and sequentially moves along the second inclined surface 431 and the first inclined surface 420 to the guide 10, so that the resistance is small, the movement is smooth, and the locking is avoided.

Specifically, referring to fig. 1, 2 and 3, the angle between the first inclined surface 420 and the moving direction of the moving assembly 320 is 5 ° to 20 °. The angle may be 5 ° or 20 °, more preferably 15 °, and the slope of the first inclined surface 420 is small, which facilitates the hanging ring 20 to slide onto the loading plate 400 along the first inclined surface 420 and the second inclined surface 431.

Preferably, referring to fig. 1, 2 and 3, the lower end of the first inclined surface 420 is adjacent to the outer wall of the guide 10, which facilitates the insertion of the first inclined surface 420 into the inner hole of the lifting ring 20 during the movement of the carrying plate 400, so that the lifting ring 20 can be easily moved onto the carrying plate 400.

In another embodiment of the present invention, referring to fig. 1, 2 and 6, the second end of the bracket 310 is bent to form a bent end 312. The curved end 312 is in the shape of an inverted "V". The moving assembly 320 includes a first roller 321 and a second roller 322. The first roller 321 and the second roller 322 are rotatably connected to the bending end 312, and the first roller 321 and the second roller 322 are disposed in an inverted "V" shape. When the curtain guide 10 is installed, the curtain guide 10 is clamped between the first roller 321, the second roller 322 and the driving wheel 220 of the main machine 200, and the first roller 321 and the second roller 322 move (roll) along the curtain guide 10 under the driving of the driving wheel 220. The first roller 321 and the second roller 322 are arranged in an inverted V shape, so that the first roller 321 and the second roller 322 can be suitable for being hung on different types and sizes of guide members 10, and the adaptability is high.

Preferably, referring to fig. 1, 2 and 6, an included angle between an axis of the first roller 321 and an axis of the second roller 322 is 90 ° to 110 °, the included angle may be 90 ° or 110 °, and more preferably 95 °, so that the first roller 321 and the second roller 322 can be stably hung on the curtain guide 10, the curtain guide 10 having a stepped telescopic type can easily roll over without rotating around the guide 10, and the included angle is appropriate in size, so that the first roller 321 and the second roller 322 cannot slip out of the guide 10 during the movement of the curtain opener along the guide 10, and the structure is stable.

Further, referring to fig. 1, 2 and 6, the bracket 310 further has an arc-shaped section 314, both ends of the arc-shaped section 314 are respectively connected with the bent end 312 and the vertical end 311, the bent end 312 and the arc-shaped section 314 are substantially hook-shaped, so that the first roller 321 and the second roller 322 are hung on the guide 10, and meanwhile, the arc-shaped section 314 provides an escape space for the guide 10 so that the bracket 310 does not interfere with the guide 10.

Further, in some embodiments, a protective shell (not shown) is further disposed on the bent end 312, the protective shell is in an inverted "V" shape, two clearance grooves are formed in the protective shell in a penetrating manner, the first roller 321 and the second roller 322 are respectively movably accommodated in the two clearance grooves, and one sides of the first roller 321 and the second roller 322 close to the guide 10 respectively extend out of the two clearance grooves, so that the first roller 321 and the second roller 322 can abut against the guide 10. In the process that the first roller 321 and the second roller 322 drive the hanging ring or the hook to move along the guide 10, the first roller 321 and the second roller 322 are protected by the protective shell, and the hanging ring, the hook and the curtain are not easy to touch the first roller 321 and the second roller 322, so that the roller is prevented from being clamped.

Further, referring to fig. 1, 2 and 6, the first end of the bearing plate 400 is provided with a connecting portion 440, the connecting portion 440 is fixedly mounted on the bending end 312 between the first roller 321 and the second roller 322, and the bearing plate 400 is located right above the guide 10, so that the bearing plate 400 bears and drives the hanging ring 20 to move with uniform stress, good motion balance and less inclination.

It is understood that the protective shell may be connected to the connecting portion 440 by means of adhesion, some other fixing connection, a detachable connection, etc., without any limitation.

In another embodiment of the present invention, referring to fig. 1 and 6, the hitch mechanism further includes a constant force spring 330. The constant force spring 330 is installed in the connecting base 350 and can rotate around its axis to extend and retract, and the first end of the bracket 310 is connected to the constant force spring 330. The support 310 can move up and down with respect to the connection base 350. Namely, the external force pulls the bracket 310 to move upwards, the constant force spring 330 will be stretched; after the external force is removed, the constant force spring 330 will elastically return to contract, thereby moving the support 310 downward.

In use, referring to fig. 1 and 6, the hanging mechanism 300 is mounted on the curtain opener, and the constant force spring provides an acting force to clamp the curtain guide 10 between the moving assembly 320 and the main frame 200 of the curtain opener. The main body 200 drives the moving component 320 to move along the guide 10, thereby driving the curtain on the guide 10 to fold or unfold during the movement, and realizing the opening or closing of the curtain.

It will be appreciated that the constant force spring 330 is a mature existing part, such as: constant force spring, constant force spring member, etc. all refer to the constant force spring 330 described in the application.

The constant force described in the application does not mean that the force magnitude does not change a little in an ideal state, but means that the force magnitude changes in a small range and is substantially close to constant, and the performance of the constant force spring 330 is related to the processing precision and the processing technology thereof.

For the thick or thin guide piece 10, when the height position of the moving component 320 is adjusted by pulling the bracket 310, the acting force of the constant force spring 330 on the moving component 320 is kept constant, when the hanging mechanism 300 is hung on the guide pieces 10 with different thicknesses, the acting force (clamping force) of the hanging mechanism 300 hung on the guide pieces 10 is kept constant, and the phenomenon that the acting force (clamping force) is too large or too small can not occur, so that the hanging mechanism 300 can be well adapted to the guide pieces 10 with different thicknesses, and the high adaptability is realized.

Referring to fig. 1 and 6, one end of the constant force spring 330 is wound into a coil 331, and the other end of the constant force spring 330 is a connection end 332.

Referring to fig. 1 and 6, a constant force spring installation cavity 360 is formed in the connection base 350, and the retractable coil 331 is horizontally installed in the constant force spring installation cavity 360.
