Description

Technical Field

[0001] This utility model belongs to the field of curtain head technology, and more specifically, relates to a cordless steel belt stabilization system. Background Technology

[0002] The steel strip head of the roller blind is usually installed on the roller blind. It is mainly used to provide upward pulling force on the curtain to balance the weight of the curtain. The more the curtain is pulled down, the more the steel strip deforms to balance the weight so that the curtain can be pulled and stopped at will.

[0003] The existing roller blind steel strip head assembly uses the following method: the steel strip, which tends to flatten, is wound into a loop. The outer end of the steel strip is fixed to the head assembly housing, and the inner end is fixed to a rotatable shaft. When the roller blind is pulled, the shaft rotates, causing the steel strip to roll inward. However, this arrangement has the following problems: Because the steel roll is made by winding a naturally straight steel strip, the steel strip itself has a tendency to flatten, providing an initial tension on the curtain. This necessitates a counterweight in the roller blind to balance this pre-set tension. However, without a counterweight, the initial pull of the roller blind will feel too heavy. It will also cause the roller blind to be pulled upwards a short distance after being pulled, meaning it cannot stop immediately after being pulled. Furthermore, as the curtain corresponding to this steel strip head is pulled downwards, the center of the steel roll tightens, resulting in uneven tension. This is especially problematic in double-layer roller blinds, causing the inner and outer layers of curtain to not align properly, thus failing to achieve complete blackout. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Compared to existing designs where the diameter of the wound steel strip is close to that of the outer diameter of the housing, the diameter of the winding shaft in this patent is significantly smaller than that of the housing. The housing rotates once, and the length of the steel strip required is shorter, thus reducing the utilization rate of the steel strip.

[0016] 2. The steel belt is naturally in a wound state, so it is unwound and stretched or wound back under the action of the transmission component. When the user pulls the curtain, there is no need to overcome the initial tension of the steel belt, so the force required is small and it is easy to pull. The tension required during the process of pulling the steel belt is the same at each stage, so there is no situation where the required tension increases as you pull, resulting in a better user experience. Since the tension generated by the steel belt changes evenly, the curtain will not bounce back upward due to excessive tension when you stop pulling it. Attached Figure Description

Detailed Implementation

[0019] Specific Implementation Example 1: Please refer to... Figures 1-10 A cordless steel belt stabilization system is used to control the opening and closing of curtains; it includes a housing 1, a transmission assembly 2 and a steel belt 3, the transmission assembly 2 is installed in the internal cavity of the housing 1, and the steel belt 3 is wound and unwound through the transmission assembly 2.

[0020] The housing 1 includes a gear housing 11, a steel coil housing 12, a mounting base 13, a cover 14, and an inner liner 16. The cover 14, the steel coil housing 12, the gear housing 11, and the mounting base 13 are connected end to end in sequence to form a chamber for accommodating the transmission assembly 2.

[0021] The mounting base 13 has a through mounting hole 131 at its center.

[0022] The gear housing 11 abuts against the end face of the mounting base 13 and is locked in place by screws 15. A planetary shaft hole 112 and a planetary shaft hole 113 are formed on the end face of the gear housing 11 away from the mounting base 13. A slot is formed on the side of the gear housing 11 near the mounting base 13, and the inner liner 16 is fitted into the slot for anti-rotation and limiting. The inner liner 16 and the inner wall of the gear housing 11 form a transmission chamber. The end face of the inner liner 16 facing the mounting base 13 abuts against the mounting base 13. A first inner liner hole 161 and a second inner liner hole 162 are formed on the end face of the inner liner 16 near the mounting base 13; the first inner liner hole 161 is coaxial with the planetary shaft hole 112 and the mounting hole 131; the second inner liner hole 162 is coaxial with the planetary shaft hole 113.

[0023] Two limiting protrusions 111 are symmetrically arranged on the outer peripheral surfaces of both sides of the gear housing 11. Mounting ears 121 are symmetrically arranged on the outer peripheral surfaces of both sides of the steel coil housing 12, extending axially toward the gear housing 11. The end faces of the gear housing 11 and the steel coil housing 12 are fitted together by a convex-concave fit, and the side of the gear housing 11 also has a groove for the mounting ears 121 to slide into for this fitting. The mounting ears 121 engage with the limiting protrusions 111 to fix the steel coil housing 12 to the gear housing 11.

[0024] The steel coil shell 12 has an unwinding shaft hole 122 and a winding shaft hole 123 on the end face near the gear shell 11. The winding shaft hole 123 is coaxially arranged with the planetary shaft hole 113 and the second inner liner hole 162.

[0025] The end faces of the cover 14 and the steel coil shell 12 are positioned by a convex-concave fit and are fixed by screws 15. A steel strip chamber is formed between the inner walls of the cover 14 and the steel coil shell 12. The upper and lower sides of the steel strip chamber are open. Two limiting protrusions 111 are symmetrically arranged on the outer circumferential surfaces of both sides of the cover 14. The cover 14 has a first cover hole and a second cover hole, respectively. The first cover hole is coaxial with the unwinding shaft hole 122; the second cover hole is coaxial with the take-up shaft hole 123; the first cover hole is symmetrical with respect to the axis and the second cover hole; the unwinding shaft hole 122 is symmetrical with respect to the axis and the take-up shaft hole 123.

[0026] The transmission assembly 2 includes a star axis 21, a planetary axis 22, a take-up shaft 23, and an unwind shaft 24.

[0027] The star shaft 21 passes sequentially through the mounting hole 131, the first inner liner hole 161, and the star shaft hole 112. One end of the star shaft 21 has a gear portion with a star gear 211, and the other end has a limiting portion with a diameter larger than the gear portion. The gear portion is located within the transmission chamber, and the limiting portion is located within the mounting hole 131. The stepped surface between the gear portion and the limiting portion abuts against the end face of the inner liner 16. A bearing 25 is sleeved on the outer periphery of the limiting portion, and the outer ring of the bearing 25 is embedded in the inner wall of the mounting hole 131, allowing the housing 1 to rotate relative to the star shaft 21. Limiting steps are raised on both the outer periphery of the limiting portion and the inner wall of the housing 1. The inner and outer rings of the bearing 25 abut against the limiting steps of the star shaft 21 and the housing 1, respectively, for axial limiting. A cross-shaped notch is provided at the tail end of the star shaft 21 for connection with a bracket for fixed installation of an external device, making the star shaft 21 a fixed component. In other feasible embodiments, the outer peripheral surface of the star shaft 21 directly contacts the inner wall of the mounting hole 131.

[0028] Planetary shaft 22 is located in the transmission chamber and is positioned outside the star shaft 21. The two ends of planetary shaft 22 pass through the second inner liner hole 162 and the planetary shaft hole 113, respectively, and are capable of rotation. A planetary gear 221 is fixedly mounted on the outside of planetary shaft 22. The planetary gear 221 meshes with the star gear 211, allowing it to rotate on its own axis while being driven to revolve around the star gear 211 due to the rotation of the housing 1.

[0029] Both the take-up shaft 23 and the unwind shaft 24 are axially stepped and positioned within the steel strip cavity. One end of the take-up shaft 23 has an anti-rotation hole, and the outer side of the planetary shaft 22 near the take-up shaft has an anti-rotation surface, allowing the take-up shaft 23 to be fitted onto the outer side of one end of the planetary shaft 22 and pass through the take-up shaft hole 123. The other end of the take-up shaft 23 is positioned within the second cover hole and has an anti-rotation surface that mates with the anti-rotation hole, allowing the planetary shaft 22 to drive the take-up shaft 23 to revolve around the star axis 21 while simultaneously rotating on its own axis. The unwind shaft 24 maintains a distance from the take-up shaft 23, with both ends passing through the unwind shaft hole 122 and the first cover hole, respectively, to enable rotation. It should be noted that the end of the unwind shaft 24 located within the first cover hole does not completely occupy the first cover hole, but only occupies half of it.

[0030] The steel strip 3 is naturally coiled, not straight, and naturally winds into a cylinder, fitting around the outer circumference of the unwinding shaft 24. A limiting block 231 is fixedly installed on the outer circumference of the unwinding shaft 24, and a limiting notch 31 is formed on the free end of the steel strip 3 on the outer side. The limiting notch 31 and the limiting block 231 engage with each other to connect the steel strip 3 and the unwinding shaft 24. After the steel strip 3 is installed, it can be observed from the opening of the steel strip chamber.

[0031] Working principle: During installation, the aforementioned cordless steel strap stabilization system is embedded into the curtain sleeve. The outer side of the sleeve is connected to the curtain fabric, and the sleeve can rotate to roll up or release the curtain. The star axis 21 is fixedly connected to the wall via an external bracket.

[0032] When the curtain is pulled down or moved up, the sleeve rotates, causing the housing 1 to rotate. Since the star axis 21 is fixed, the planetary axis 22 is driven by the housing 1 to revolve around the star axis 21. Simultaneously, due to the meshing relationship between the two, the planetary axis 22 also rotates on its own axis. The rotation of the planetary axis 22 also drives the rotation of the take-up shaft 23. The direction of the planetary axis 22's rotation determines the winding or unwinding of the steel belt 3. When the curtain is pulled down, as the planetary axis 22 rotates in the forward direction, the take-up shaft 23 rotates and pulls out the steel belt 3, causing it to rewind on the take-up shaft 23. Since the steel belt 3 itself has a winding tendency, the more the steel belt 3 is wound on the take-up shaft 23, the greater the pulling force generated by the steel belt 3, and the more effectively it can pull the pulled-down curtain, preventing the curtain from falling due to its own weight.

[0033] Since the steel belt 3 is naturally rolled up, the elastic force generated by the steel belt 3 increases evenly during the process of pulling down the curtain. The elastic force will not increase as it is pulled, thus avoiding the problem that the curtain will move upward due to excessive tension of the steel belt 3 and cannot be stopped.

[0034] Furthermore, since the steel strip 3 is continuously wound around the take-up shaft 23, and the outer diameter of the take-up shaft 23 is significantly smaller than the outer diameter of the sleeve and the housing 1, the steel strip 3 required for the same length of curtain will be much shorter. For example, if the curtain needs to be fully pulled down and the housing 1 needs to be turned 30 times, then the take-up shaft 23 also needs to be turned 30 times. However, due to its smaller outer diameter, the length of the steel strip 3 is shorter when it is turned 30 times.

[0035] Additionally, when the curtain fabric is too long, the number of steel strips 3 can be increased. Specifically, a steel roll shell 12, steel strips 3, a winding shaft 23, an unwinding shaft 24, and a cover 14 are added axially towards the center of the curtain fabric on the end face of the cover 14. The added winding shaft 23 is integrated with the original winding shaft 23 to prevent rotation. One end of the added unwinding shaft 24 is located in the first cover hole of the original cover 14, and the other end is located in the first cover hole of the added cover 14. The added steel roll shell 12 can also be integrated with the cover 14 by engaging with the limiting protrusion 111 via the mounting ear 121.
