[0042] Example 1

[0043] The blind is used in the interior of the car and can provide a shielding function for the rear storage space in the car, combining beauty and practicality. Its structure mainly consists of installing a curtain in a shaft tube with a retractor inside. The curtain can be pulled out of the shaft tube and unfolded to provide a shielding function for the rear storage space of the car, and the retractor can be used to automatically retract the curtain into the shaft tube for easy storage. However, since the length of the shaft tube usually matches the length of the two side walls of the car body in the rear storage space of the car, the blind is still long after being rolled up, which makes it inconvenient to store. At present, some blinds are set in a foldable form. However, the folding and unfolding operation of such blinds is complicated, and the folding joint is unstable. When the blind is unfolded, the curtain may produce wavy wrinkles and easily shake and deform.

[0044] In order to solve the above problems, Figures 1-6As shown, this embodiment provides a foldable screen curtain, which includes a first curtain assembly 1, a second curtain assembly 2, a first locking structure 3 and a second locking structure 4. The first curtain assembly 1 is provided with a first mounting member 11 and a second mounting member 12 at opposite ends thereof, and a third mounting member 21 and a fourth mounting member 22 are provided with a third mounting member 21 and a fourth mounting member 22 at opposite ends thereof. The first mounting member 11 and the third mounting member 21 are pivotally connected by a first rotating shaft 61 to form a first rotating structure, and the second mounting member 12 and the fourth mounting member 22 are pivotally connected by a second rotating shaft 62 to form a second rotating structure; the first locking structure 3 includes a first locking buckle 31 and a first slider 32, the first locking buckle 31 can limit the relative position of the first curtain assembly 1 and the second curtain assembly 2, the first slider 32 includes a sliding portion 321 and a covering portion 322 arranged at an angle, the covering portion 322 is covered on the first locking buckle 31, and the sliding portion 321 is slidably provided on the side wall of the first rotating structure; the second locking structure 4 includes a second locking buckle 41, and the second locking buckle 41 can limit the relative position of the first curtain assembly 1 and the second curtain assembly 2.

[0045] The first curtain assembly 1 and the second curtain assembly 2 are pivotally connected at opposite ends by a first rotating shaft 61 and a second rotating shaft 62, and the first curtain assembly 1 and the second curtain assembly 2 can be switched between the unfolded state and the folded state by rotating the first rotating shaft 61 and the second rotating shaft 62. Figure 1 As shown, when the foldable curtain is needed, the first curtain assembly 1 and the second curtain assembly 2 are rotated so that the two are arranged horizontally. At this time, the foldable curtain is in the unfolded state and can be normally used in the rear storage space to cover items; Figure 4 As shown, when the foldable curtain is not in use, the first curtain assembly 1 and the second curtain assembly 2 are rotated so that they are folded in half. At this time, the foldable curtain is in a folded state and can be easily stored, greatly saving storage space. The first locking buckle 31 and the second locking buckle 41 can jointly limit the relative position of the first curtain assembly 1 and the second curtain assembly 2 at opposite ends of the foldable curtain, so that the foldable curtain can remain in the unfolded state. The positioning of the foldable curtain in two directions can ensure its stability in the unfolded state. In addition, the first slider 32 includes a sliding portion 321 and a cover portion 322 arranged at an angle, which can strengthen the first rotating structure from two directions, making the joint between the first mounting member 11 and the third mounting member 21 stable and not easily shaken or deformed. In addition, the foldable curtain is not prone to wave wrinkles, ensuring good flatness of the foldable curtain.

[0046] It should be noted that the first curtain assembly 1 and the second curtain assembly 2 in this embodiment have the same structure, specifically including a curtain fabric and an outer tube and a handle provided at opposite ends of the curtain fabric. A retractor is provided in the outer tube so that the curtain fabric can be rolled up in the outer tube, and the curtain fabric can be easily pulled out and unfolded by pulling the handle. In this embodiment, the first mounting member 11 and the third mounting member 21 are outer tubes, and the second mounting member 12 and the fourth mounting member 22 are handles, that is, the first locking structure 3 is used to limit the relative position of the two outer tubes, and the second locking structure 4 is used to limit the relative position of the two handles. It should be noted that for the sake of brevity, the specific structure and implementation principle of the first curtain assembly 1 and the second curtain assembly 2 are not described in detail herein, and reference is made to the specific structure and implementation principle of common screen curtains in the prior art.

[0047] Specifically, if Figure 1 、 Figure 2 As shown, the first locking structure 3 also includes a first elastic member 33, the first locking buckle 31 is rotatably arranged on the first mounting member 11, the first end of the first locking buckle 31 has a first locking tongue 311, the third mounting member 21 is protruding with a first locking portion 211, and a first elastic member 33 is arranged between the second end of the first locking buckle 31 and the first mounting member 11. The first elastic member 33 is configured to drive the first locking tongue 311 to abut against the first locking portion 211.

[0048] like Figure 1 、 Figure 2 As shown, the first elastic member 33 applies a continuous driving force to the first locking buckle 31 to push the first locking buckle 31 to rotate until it abuts the first locking portion 211, thereby fixing the first mounting member 11 and the third mounting member 21, thereby limiting the relative position of the first curtain assembly 1 and the second curtain assembly 2, and maintaining the foldable curtain in the deployed state. The cooperation between the first locking buckle 31 and the first locking portion 211 effectively limits the relative position of the first curtain assembly 1 and the second curtain assembly 2, ensuring that the first curtain assembly 1 and the second curtain assembly 2 remain stable in the deployed state, preventing the foldable curtain from suddenly folding or shifting during use, thereby improving its reliability. The configuration of the first elastic member 33 makes the locking process simple and quick. The user only needs to rotate the first curtain assembly 1 and the second curtain assembly 2 to the deployed state, and the first locking buckle 31 automatically locks under the drive of the first elastic member 33, reducing operational complexity and improving user experience.

[0049] Specifically, the first elastic member 33 in this embodiment is a compression spring. It should be noted that other elastic structures in the prior art that can drive the first locking tongue 311 to abut against the first locking portion 211 can also be used as the first elastic member 33 in this embodiment, and this embodiment does not limit this.

[0050] In this embodiment, if Figure 1 、 Figure 2As shown, the first mounting member 11 has a first mounting wall 111, on which a third rotating shaft 63 is disposed. The third rotating shaft 63 and the first rotating shaft 61 extend in the same direction, and the first locking buckle 31 is rotatably mounted on the third rotating shaft 63. The first locking buckle 31 is rotatably mounted on the third rotating shaft 63, so that the first locking buckle 31 can maintain a stable trajectory during rotation, avoiding structural instability caused by shaking or deviation, which affects the locking and unlocking effects.

[0051] Specifically, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the end of the cover portion 322, which is away from the second end of the first locking buckle 31, is provided with a first abutting portion 3221. The second end of the first locking buckle 31 is provided with a first pressing protrusion 312. The first abutting portion 3221 can abut the first pressing protrusion 312 to drive the first locking tongue 311 away from the first locking portion 211. When the foldable curtain needs to be folded, the first slider 32 is slid to move the first abutting portion 3221 toward the first pressing protrusion 312. The first abutting portion 3221 abuts the first pressing protrusion 312, thereby driving the first locking buckle 31 to rotate, thereby moving the first locking tongue 311 away from the first locking portion 211 to unlock the curtain. After unlocking, the first curtain assembly 1 and the second curtain assembly 2 are rotated to fold them in half, completing the stowage of the foldable curtain. Unlocking can be achieved by pushing the first slider 32 without directly acting on the first locking buckle 31, simplifying the operation process and improving the user experience. When the foldable curtain needs to be unfolded, the first curtain assembly 1 and the second curtain assembly 2 are first rotated to a horizontal position when the first abutting portion 3221 abuts against the first pressing protrusion 312, and then the first slider 32 is slid to make the first abutting portion 3221 move in a direction away from the first pressing protrusion 312. The first locking buckle 31 is reset to the state where the first locking tongue 311 abuts against the first locking portion 211 under the action of the first elastic member 33 to achieve fixed locking.

[0052] Specifically, a limiting protrusion 51 is provided on one of the sidewalls of the first rotating structure and the sliding portion 321, while a sliding groove 52 is provided on the other side, extending along the length of the first rotating structure. The limiting protrusion 51 slidably engages with the sliding groove 52. The sliding engagement between the limiting protrusion 51 and the sliding groove 52 ensures the stable movement of the first slider 32 on the first rotating structure, allowing it to move only along the length of the first rotating structure, preventing it from deflecting or shaking during movement. By providing the limiting protrusion 51 and the sliding groove 52, the movement range of the first slider 32 can be precisely controlled to prevent it from sliding excessively.

[0053] In this embodiment, if Figure 1 、 Figure 2As shown, a limiting protrusion 51 is provided on the first rotating structure, more specifically, on the first mounting member 11, and a sliding groove 52 is provided on the sliding portion 321. Specifically, the leftward limit position of the first slider 32 is when the first slider 32 is exactly in the middle of the first rotating structure, thereby reinforcing the first rotating structure in two directions and preventing the first mounting member 11 and the third mounting member 21 from shaking. The rightward limit position of the first slider 32 is when the first abutting portion 3221 of the first slider 32 exactly abuts the first pressing protrusion 312.

[0054] In other embodiments, the limiting protrusion 51 is provided on the first slider 32, and the sliding groove 52 is provided on the first rotating structure. It should be noted that the specific configuration is determined according to actual needs and is not limited in this embodiment.

[0055] Specifically, if Figure 1 、 Figure 3 As shown, the second locking structure 4 further includes a second elastic member 42, a second locking buckle 41 is rotatably provided on the second mounting member 12, a first end of the second locking buckle 41 has a second locking tongue 411, the fourth mounting member 22 is convexly provided with a second locking portion 221, and a second elastic member 42 is provided between the second end of the second locking buckle 41 and the second mounting member 12, and the second elastic member 42 is configured to drive the second locking tongue 411 to abut against the second locking portion 221. The second elastic member 42 applies a continuous driving force to the second locking buckle 41, pushing the second locking buckle 41 to rotate until it abuts against the second locking portion 221, thereby fixing the second mounting member 12 and the fourth mounting member 22 to limit the relative position of the first curtain assembly 1 and the second curtain assembly 2, so that the foldable curtain remains in the unfolded state. Through the cooperation of the second locking buckle 41 and the second locking portion 221, the relative position of the first curtain assembly 1 and the second curtain assembly 2 can be effectively limited, ensuring that they remain stable in the unfolded state, preventing the folding curtain from suddenly folding or shifting in unexpected situations, thereby improving reliability; the configuration of the first elastic member 33 makes the locking process simple and quick. The user only needs to rotate the first curtain assembly 1 and the second curtain assembly 2 to the unfolded state, and the second locking buckle 41 will automatically lock under the drive of the second elastic member 42, reducing the complexity of operation and improving the user experience.

[0056] Specifically, the second elastic member 42 in this embodiment is a compression spring. It should be noted that other elastic structures in the prior art that can drive the second locking tongue 411 to abut against the second locking portion 221 can also be used as the second elastic member 42 in this embodiment, and this embodiment is not limited to this.

[0057] Specifically, if Figure 3 、 Figure 6As shown, the second mounting member 12 has a second mounting wall 121, on which a fourth rotating shaft 64 is disposed. The fourth rotating shaft 64 and the second rotating shaft 62 extend in the same direction, and the second locking buckle 41 is rotatably mounted on the fourth rotating shaft 64. The second locking buckle 41 is rotatably mounted on the fourth rotating shaft 64, so that the second locking buckle 41 can maintain a stable trajectory during rotation, avoiding structural instability caused by shaking or deviation, which affects the locking and unlocking effects.

[0058] Specifically, if Figure 3 、 Figure 6 As shown, the second end of the second locking buckle 41 is provided with a second pressing protrusion 412. Pressing the second pressing protrusion 412 drives the second locking tongue 411 away from the second locking portion 221. When the foldable curtain needs to be folded, the second pressing protrusion 412 is directly pressed to rotate the second locking buckle 41, thereby moving the second locking tongue 411 away from the second locking portion 221 to unlock the curtain. After unlocking, the first curtain assembly 1 and the second curtain assembly 2 are rotated to fold them in half, completing the stowage of the foldable curtain. The second pressing protrusion 412 can be directly pressed manually to unlock the second locking structure 4, allowing the user to complete the unlocking operation more quickly. When the foldable curtain needs to be unfolded, the second pressing protrusion 412 is pressed while the first curtain assembly 1 and the second curtain assembly 2 are rotated to a horizontal position. The second pressing protrusion 412 is then released. The second locking buckle 41, under the action of the second elastic member 42, returns to a position where the second locking tongue 411 abuts the second locking portion 221, achieving a secure lock.

[0059] Specifically, the second mounting member 12 and the fourth mounting member 22 are matched in concave and convex manner. By matching the second mounting member 12 and the fourth mounting member 22 in concave and convex manner, the second mounting member 12 and the fourth mounting member 22 can be more accurately positioned and docked together, while improving the stability of the docking.

[0060] Example 2

[0061] A foldable screen curtain is provided in this embodiment. The structure of the foldable screen curtain provided in this embodiment is substantially similar to that of the foldable screen curtain provided in the first embodiment, except that the second locking structure 4 of the foldable screen curtain provided in this embodiment further includes a second slider 43 .

[0062] like Figure 7 、 Figure 8As shown, the second slider 43 is mounted on the second locking buckle 41. A second abutting portion 431 is protruded from one end of the second slider 43, which is away from the second end of the second locking buckle 41. The second abutting portion 431 can press against the second pressing protrusion 412 to drive the second locking tongue 411 away from the second locking portion 221. When the foldable curtain needs to be folded, the second slider 43 is slid to move the second abutting portion 431 toward the second pressing protrusion 412. This causes the second abutting portion 431 to abut against the second pressing protrusion 412, thereby driving the second locking buckle 41 to rotate, thereby moving the second locking tongue 411 away from the second locking portion 221 to unlock the curtain. After unlocking, the first curtain assembly 1 and the second curtain assembly 2 are rotated to fold them in half, completing the stowage of the foldable curtain. Unlocking can be achieved by pushing the second slider 43 without directly acting on the second locking buckle 41 itself, simplifying the operation process and improving the user experience. When the foldable curtain needs to be unfolded, the first curtain assembly 1 and the second curtain assembly 2 are first rotated to a horizontal position when the second abutting portion 431 abuts against the second pressing protrusion 412, and then the second slider 43 is slid to make the second abutting portion 431 move in a direction away from the second pressing protrusion 412. The second locking buckle 41 is reset to the state where the second locking tongue 411 abuts against the second locking portion 221 under the action of the second elastic member 42 to achieve fixed locking.

[0063] In this embodiment, if Figure 7 、 Figure 8 As shown, a third elastic member 44 is disposed between the second slider 43 and the second mounting wall 121. The third elastic member 44 is configured to drive the second abutment portion 431 to move away from the second pressing protrusion 412. The second slider 43 is elastically connected to the second mounting member 12 via the third elastic member 44. When the foldable curtain is to be unfolded, the second slider 43 is moved away from the second pressing protrusion 412 by the third elastic member 44, eliminating the need for manual sliding, making the operation simple and quick, and improving the user experience.

[0064] In this embodiment, the third elastic member 44 is a tension spring. It should be noted that other elastic structures in the prior art that can drive the second abutting portion 431 to move away from the second pressing protrusion 412 can also be used as the third elastic member 44 in this embodiment, and this embodiment is not limited to this.
