[0055] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0056] Example 1:

[0057] An electrically operated curtain system. For example... Figure 1As shown, the system includes a curtain assembly 1, a pull cord mechanism 2, a drive assembly 3, and a guide mechanism 4. The pull cord mechanism 2 connects to both the drive assembly 3 and the guide mechanism 4, and the guide mechanism 4 connects to the curtain assembly 1. Under the action of the drive assembly 3, the pull cord mechanism 2 drives the guide mechanism 4 to reciprocate, and this reciprocating motion of the guide mechanism 4 enables the curtain assembly 1 to unfold and retract. This electric curtain system is suitable for installation in scenarios requiring light blocking, meeting user needs for comfort, privacy, sun shading, and UV protection, and is particularly suitable for installation on car side windows.

[0058] Example 2:

[0059] Based on Example 1, such as Figure 1 , Figure 3 and Figure 4 As shown, the curtain assembly 1 includes a pull plate 1-1, a curtain 1-2, an inner tube assembly 1-3, and an outer tube assembly 1-4. The curtain 1-2 is connected to and wound around the inner tube assembly 1-3. The inner tube assembly 1-3 is located inside the outer tube assembly 1-4, and the gap between the inner tube assembly 1-3 and the outer tube assembly 1-4 can accommodate the wound curtain 1-2. A slot is formed on the surface of the outer tube assembly 1-4 along the axial direction. The curtain 1-2 passes through the slot and connects to the pull plate 1-1. The pull plate 1-1 is connected to a guide mechanism 4. The inner tube assembly 1-3 and the outer tube assembly 1-4 are coaxially arranged, which facilitates the stability of the curtain 1-2 during unfolding and retraction. When the curtain 1-2 is retracted, it is wound inside the inner tube assembly 1-3, occupying little space. Preferably, the curtain 1-2 is made of perforated yarn fabric. Preferably, a power component is provided inside the inner tube assembly 1-3 so that the curtain 1-2 is in a state of being wound on the inner tube assembly 1-3 when it is not subjected to the force of the pull mechanism 2 and the guide mechanism 4.

[0060] Example 3:

[0061] Based on Example 1 or 2, such as Figures 2 to 5 as well as Figures 8 to 11As shown, the pull wire mechanism 2 includes a first pull wire 2-2, a second pull wire 2-3, a fixed pull wheel 2-5, and a slider assembly 2-4; one end of the first pull wire 2-2 is wound around the drive assembly 3, and the other end is connected to one end of the slider assembly 2-4; one end of the second pull wire 2-3 is wound around the drive assembly 3, and the other end passes over the fixed pull wheel 2-5 and is connected to the other end of the slider assembly 2-4; the slider assembly 2-4 is mounted on the guide mechanism 4 and can slide along the guide mechanism 4; the fixed pull wheel 2-5 is mounted on the guide mechanism 4. The slider assembly 2-4 includes a wire tolerance adjuster and a slider 5-2; the wire tolerance adjuster is disposed on the slider 5-2, and the slider 5-2 is slidably connected to the guide mechanism; the wire tolerance adjuster includes a spring 5-3, a first adapter 5-1, and a second adapter 5-4; the two ends of the spring 5-3 are respectively connected to the first adapter 5-1 and the second adapter 5-4; the first adapter 5-1 and the second adapter 5-4 are respectively connected to the second wire 2-3 and the first wire 2-2.

[0062] To ensure system stability, the pull wires of the pull mechanism 2 need to be kept taut. However, due to tolerances in the mating components, ensuring the first pull wire 2-2 and the second pull wire 2-3 are taut during installation is challenging. To address this difficulty and improve efficiency, a pull wire tolerance adjuster is installed on the slider assembly 2-4. The spring 5-3 in the adjuster simplifies installation, improves efficiency, and ensures the pull wires remain taut, thus ensuring stable operation of the electric curtain system. Furthermore, the pull wire material shrinks under different ambient temperatures, affecting the pull wire tension and consequently operational stability. The pull wire tolerance adjuster effectively compensates for these environmental influences.

[0063] Example 4:

[0064] Based on embodiment 3, the pull-wire mechanism 2 further includes a silent sliding angle 2-1, such as... Figure 6 and Figure 7 As shown, the silent sliding angle 2-1 is located at the connection between the slider assembly 2-4 and the guide mechanism 4, and a noise-reducing groove is provided on the contact surface between the silent sliding angle 2-1 and the guide mechanism 4.

[0065] The slider assembly 2-4 slides along the guide rail 4-2 of the guide mechanism 4 via the action of the pull wire mechanism 2. A silent sliding angle 2-1 is provided at the connection between the slider assembly 2-4 and the guide rail 4-2. This increases the base area of ​​the slider assembly 2-4 and the guide rail 4-2, making the sliding process stable and ensuring the smooth operation of the curtain assembly 1 during unfolding and retraction. Furthermore, a sound-absorbing groove is provided on the contact surface between the silent sliding angle 2-1 and the guide rail 4-2 to reduce noise during operation. In addition, the pull wire mechanism 2 has fewer metal parts, reducing friction noise between metal parts during operation and significantly lowering the overall noise level.

[0066] Example 5:

[0067] Based on Examples 1, 2, or 3, such as Figure 1 , Figure 2 and Figure 5 As shown, the drive assembly 3 includes a drive motor 3-1 and a winding reel 3-2; the drive motor 3-1 is connected to the winding reel 3-2 and can drive the winding reel 3-2 to rotate; the winding reel 3-2 is wound with the pull wire of the pull wire mechanism. The drive assembly 3 also includes a worm gear reducer. Figure 1 , Figures 3 to 5 , Figure 10-12 As shown, the guiding mechanism 4 includes a guide rail 4-2, a support rod 4-1, a front stop limiting block 4-4, and a rear stop limiting block 4-5. The support rod 4-1 is disposed within the guide rail 4-2 and can move along the guide rail 4-2. One end of the support rod 4-1 is connected to the pull plate 1-1 of the curtain assembly 1, and the other end is connected to the slider assembly 2-4 of the pull cord mechanism 2. The front stop limiting block 4-4 and the rear stop limiting block 4-5 are both disposed on the guide rail 4-2 and can limit the slider assembly 2-4 of the pull cord mechanism 2. The other end of the support rod 4-1 is provided with a rotating head 5-5, and the support rod 4-1 is connected to the slider assembly 2-4 of the pull cord mechanism 2 through the rotating head 5-5.

[0068] The drive motor 3-1 rotates forward or reverse, driving the slider assembly 2-4 of the cable pulling mechanism 2 to push the support rod 4-1, thereby unfolding or retracting the curtain 1-2 of the curtain assembly 1. When the slider assembly 2-4 moves to the position of the front stop block 4-4, the curtain 1-2 has reached its maximum unfolding stroke; when the slider assembly moves to the position of the rear stop block 4-5, the curtain 1-2 is completely retracted into the outer tube assembly 1-4 and wound onto the inner tube assembly 1-3. The front stop block 4-4 and the rear stop block 4-5 ensure that the slider assembly 2-4 does not detach from the guide rail 4-2, guaranteeing operational stability.

[0069] The support rod 4-1 is connected to the slider assembly 2-4 of the pull-wire mechanism 2 via the rotating head 5-5. When the curtain 1-2 of the curtain assembly 1 is unfolded, the support rod 4-1 pushes the curtain 1-2 to unfold. Due to the retraction force of the curtain 1-2, the support rod 4-1 will bend and deform. By setting the rotating head 5-5, the degree of freedom of movement of the support rod 4-1 is increased, which effectively improves the bending state of the support rod 4-1 during the unfolding of the curtain 1-2 and straightens the support rod 4-1.

[0070] Example 6:

[0071] Figure 1 This is the fully extended state of the electric curtain system 1. Its overall structure includes: curtain assembly 1, pull cord mechanism 2, drive assembly 3, and guide mechanism 4. The pull cord mechanism 2 is driven by a drive motor 3-1 to drive the winding wheel 3-2. The forward and reverse rotation of the drive motor controls the tightening and releasing of the first pull cord 2-2 and the second pull cord 2-3, which in turn pulls the slider assembly 2-4 and the support rod 4-1 to move along the guide rail 4-2, thereby realizing the opening and closing of the curtain 1-2.

[0072] Figure 2 The drive assembly 3, with drive motor 3-1 preferably being a micro DC motor, incorporates a worm gear reducer to provide high torque output. It connects to the winding wheel 3-2 via gears, fixing one end of the first pull cable 2-2 to the slot of the winding wheel 3-2 and correctly winding the cable into the cable guide groove. The other end is fixed to the slider assembly 2-4. One end of the second pull cable 2-3 is fixed to the slot of the winding wheel 3-2, and the other end passes over the fixed cable wheel 2-5 and is fixed to the slider assembly 2-4, forming a closed loop for the pull cable. The forward and reverse rotation of the drive motor 3-1 controls the release and retraction of the pull cable.

[0073] Figure 3 It is a curtain assembly 1, which includes a pull plate 1-1, a curtain 1-2, an inner tube assembly 1-3, and an outer tube assembly 1-4. The curtain 1-2 is preferably a perforated yarn fabric, and the inner tube assembly 1-3 provides power for the winding of the curtain 1-2. Driven by the drive assembly 3, the motor 3-1 reverses (counterclockwise), releasing the second pull cable 2-3 and tightening the first pull cable 2-2. The slider assembly 2-4 drives the support rod 4-1 to move along the guide rail 4-2. One end of the support rod 4-1 is fixed to the pull plate 1-1, and the other end is fixed to the slider assembly 2-4. The slider assembly 2-4 moves to the front limit stop 4-4, which is the maximum stroke of the curtain 1-2. Driven by the drive motor 3-1, the second pull cable 2-3 tightens, releasing the first pull cable 2-2. The slider assembly 2-4 drives the support rod 4-1 to move along the guide rail 4-2. The slider assembly 2-4 moves to the rear limit stop 4-5, and the curtain 1-2 retracts (closes). This is one cycle of the curtain 1-2 unfolding and retracting.

[0074] Figure 4When the curtain 1-2 is unfolded, the state of the pull cable mechanism 2 is such that the drive assembly 3 controls the pull cable, the support rod 4-1 and the slider assembly 2-4 to move along the guide rail 4-2 to the front limit stop 4-4. At this time, the curtain is fully unfolded, which is the maximum stroke of the curtain. Figure 5 When the curtain 1-2 is retracted (wound), the state of the pull cable mechanism 2 is controlled by the drive assembly 3. The pull cable, support rod 4-1 and slider assembly 2-4 move along the guide rail 4-2 to the rear stop limit block 4-5. At this time, the curtain is completely closed, which is the closing point of the curtain.

[0075] Figure 6 To determine the running posture of the slider assembly 2-4 within the guide rail 4-2, the first pull wire 2-2 and the second pull wire 2-3 are used to cause the slider assembly 2-4 to move along the guide rail 4-2. For example... Figure 7 As shown, by increasing the silent sliding angle 2-1, the contact area between the slider assembly 2-4 and the guide rail 4-2 is increased, making the curtain unfolding and retracting operation smoother. By adding some noise-absorbing grooves to the contact surface between the silent sliding angle 2-1 and the guide rail 4-2, the silent sliding angle 2-1 is free from friction noise during the unfolding and retracting operation of the curtain 1-2, thereby reducing noise.

[0076] Figure 8 The draw wire tolerance adjuster, located on the slider assembly 2-4, includes a first adapter 5-1, a second adapter 5-4, and a spring 5-3. The draw wire tolerance adjuster is mounted on the slider 5-2 of the slider assembly 2-4. The purpose of the draw wire tolerance adjuster is to facilitate the assembly of the draw wire, such as... Figure 9 As shown, since the first pull wire 2-2 and the second pull wire 2-3 are tightly fitted with the winding wheel 3-2, and the related mating parts have certain tolerance errors, they are difficult to install under normal conditions. This design effectively improves assembly efficiency. The second purpose of the pull wire tolerance adjuster is to adjust the dimensional tolerance of the pull wire mechanism 2. Materials have a certain degree of shrinkage under different environmental temperatures, which affects the dimensions of product components and can lead to product failure. This design can effectively compensate for dimensional tolerance losses due to environmental factors.

[0077] Figure 10 and 11 This is a strut travel adjuster, comprising a rotating head 5-5, a strut 4-1, and a slider 5-2. Its purpose is to adjust the strut travel when the curtain 1-2 is being lifted. The strut 4-1 pushes the curtain 1-2 to rise, and due to the reaction force of the curtain 1-2's retraction, the strut 4-1 may bend and deform. Figure 12 As shown in the image of strut 4-1 (bent state after lifting), by adding a rotating head 5-5, the degree of freedom of movement of strut 4-1 is increased, effectively improving the lifting state of strut 4-1. Figure 12 The middle strut 4-1 (normal state after lifting) is shown.

[0078] The technical solution of this utility model features a pull-cord mechanism 2 with fewer metal parts, eliminating friction noise between metal parts and significantly reducing overall noise. Because the pull-cord mechanism 2 drives the curtain 1-2, the overall weight of the product is significantly reduced compared to competing products. By setting the front stop limit 4-4 and the rear stop limit block 4-5, the travel trajectory of the curtain 1-2 can be effectively set. The opening and closing of the curtain 1-2 is a hard stop (mechanical stop), preventing structural damage caused by exceeding the travel limit and improving stability. The addition of a silent sliding angle 2-1 ensures that the guide rail 4-2 and slider 5-2 operate without noise. The addition of a pull-cord tolerance adjuster effectively coordinates dimensional errors of different materials, facilitating installation and improving operational stability. The addition of a support rod adjuster effectively adjusts the lifting state of the support rod 4-1 when the curtain 1-2 is opened.

[0079] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
