Technical Field
[0001] This utility model relates to the field of curtain technology, specifically to a curtain blackout component and a curtain. Background Technology
[0002] Curtains are decorative items made of fabric or other materials used to cover windows. They can be used to adjust the brightness of indoor light and privacy, while also serving a decorative purpose. Roller blinds are a type of blind that is raised and lowered using a roller system. They are typically made of a long strip of curtain fabric or material, and the roller system allows the blind to be easily rolled up or pulled down to adjust the light and privacy of the window.
[0003] CN116464380A discloses a roller blind, comprising: a roller tube, a blind body, a first power assembly, and a second power assembly; the roller tube has a first end and a second end opposite to each other; both the first power assembly and the second power assembly are disposed at the ends of the roller tube, the first power assembly having a motor, a transmission component, and a clutch, the transmission component being connected to the roller tube, and the clutch being connected to the motor and the transmission component and adapted to switch between linkage and non-linkage between the two; the second power assembly has multiple main controllers connected in series, each main controller including a housing, a main shaft, a spring, and an adjusting component, the housing being connected to the roller tube, the main shaft passing through the housing and having a first plug-in end and a second plug-in end for plugging and cooperating with adjacent main controllers, the spring being disposed within the housing, and the adjusting component being adapted to adjust the spring force of the spring. This extends the service life of the motor, reduces energy consumption, enables switching between electric and manual operation of the blind, has a low failure rate, and can accurately match the driving requirements of different blinds during winding.
[0004] Due to structural limitations, the aforementioned technical solution results in the curtain not fitting snugly against the window, leading to light leakage on both sides. To avoid this, blackout grooves, as disclosed in patent CN203252420U, are typically installed on the walls on both sides of the curtain, with the curtain sides embedded into these grooves. However, to allow the roller to rotate, both ends of the roller must have a first power component and a second power component to enable rotation. This means the curtain fabric cannot completely cover the roller. Even with the addition of blackout grooves, the presence of the first and second power components creates gaps below them. Increasing the length of the blackout grooves would also interfere with the normal opening and closing of the curtain. Therefore, complete blackout cannot be achieved. Utility Model Content
[0005] The purpose of this utility model is to solve the above-mentioned problems and provide a curtain blackout component. This blackout component adds a blackout component to the blackout groove, and the end of the blackout component extends into the curtain shell and is located on the front and / or back side of the curtain fabric. In addition, this utility model also provides a curtain that, under the action of the blackout component, can effectively fill the gap between the transmission component at the end of the roller and the blackout groove, thereby improving the blackout effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1
[0021] refer to Figures 1-5 A curtain blackout component 2, wherein one end of the blackout component 2 is connected to the top of an external blackout groove 1, and the external blackout groove 1 is symmetrically arranged on a wall 8 and located below the external curtain shell 4, and the other end of the blackout component 2 extends into the curtain shell 4, and the blackout component 2 is located on the front and / or back side of the curtain fabric 6.
[0022] In this design, when installing the curtains, space needs to be reserved to install the blackout groove 1 on the walls 8 on both sides of the curtain. In order to ensure that the two sides of the curtain fabric 6 do not leak light, the two sides of the curtain fabric 6 need to be embedded in the blackout groove 1. Without the blackout component 2, there will be a gap between the curtain fabric 6 and the wall 8, that is, between the drive and transmission components of the external curtain and the blackout groove 1. When looking directly at the curtain, this gap is not easy to see. Of course, the "direct view" mentioned here refers to a viewing angle that is completely horizontal with respect to the gap. However, the height of the curtain installation is generally close to the ceiling of the room, so the staff in the room can see it clearly from an upward angle, which means that the curtain leaks light. By adding the blackout component 2 to the blackout groove 1, the end of the blackout component 2 extends towards the curtain shell 4 and is located on the front and / or back side of the curtain fabric 6.
[0023] Preferably, the light-blocking assembly 2 includes a connector 21 and a light-blocking plate 22. The connector 21 has a through groove 23 that matches the light-blocking groove 1. The horizontal cross-section of the connector 21 is U-shaped. The connector 21 is movably connected to the light-blocking groove 1. The top of the connector 21 contacts the bottom of the external curtain shell 4. The light-blocking plate 22 is connected to one or both sides of the top of the connector 21. The free end of the light-blocking plate 22 is located inside the curtain shell 4. The curtain fabric 6 is located inside the through groove 23.
[0024] In practical use, the flexible connection between the connector 21 and the light-blocking groove 1 can be increased. This is because the installation height of each curtain shell 4 is not uniform, and the installation height of various driving components inside the curtain shell 4 is also not uniform. If only the light-blocking groove 1 is used to achieve light blocking, not only is height control processing required, but also the top of the light-blocking groove 1 needs to be processed to match the structure of the driving components and transmission components on the curtain. This will undoubtedly take more time and cost.
[0025] By using connector 21, a through groove 23 matching the light-blocking groove 1 is provided inside connector 21, and the horizontal cross section of connector 21 is U-shaped, that is, the general shape of connector 21 matches the light-blocking groove 1. This ensures the flexibility of the light-blocking plate 22 without affecting the raising and lowering of the curtain. Moreover, the vertical position of the light-blocking plate 22 can be adjusted according to the height of the drive and transmission components inside the curtain. Even if the top of the light-blocking groove 1 cannot contact the bottom of the curtain shell 4, the top of connector 21 can be adjusted to contact the bottom of the curtain shell 4 to ensure the best light-blocking effect.
[0026] Furthermore, the light-blocking plate 22 can be located on one or both sides of the top of the connector 21. In this embodiment, based on the premise of cost-effective light blocking, the light-blocking plate 22 is selected to be located on one side of the top of the connector 21, and preferably on the back side of the curtain fabric 6, to ensure the aesthetics of the curtain.
[0027] More preferably, the side of the light-blocking plate 22 closest to the curtain fabric 6 is curved. By setting the curved surface, the horizontal cross-section of the light-blocking plate 22 decreases continuously from the bottom to the top of the light-blocking plate 22, which provides a guiding surface for the curtain fabric 6, ensuring that the curtain fabric 6 will not detach from the light-blocking groove 1 when the curtain fabric 6 is raised to its highest position.
[0028] Furthermore, the free end of the light-blocking plate 22 extends away from the curtain fabric 6. The light-blocking plate 22 can also be configured such that its free end extends away from the curtain fabric 6, that is, the light-blocking plate 22 is bent away from the curtain fabric 6. In order to ensure the stability of the curtain fabric 6, a counterweight is usually provided at the lower end of the curtain fabric 6. The description of the counterweight has been disclosed in Chinese patent CN110644914A, so it will not be described in detail here. The thickness of the counterweight is generally greater than that of the curtain fabric 6. Therefore, after the light-blocking plate 22 is bent away from the curtain fabric 6, it can achieve the function of widening, which makes it easier to guide the counterweight back into the light-blocking groove 1 when the curtain fabric 6 is raised to the highest point.
[0029] In this embodiment, the connector 21 includes a horizontally arranged first U-shaped plate 211, a second U-shaped plate 212 connected to the bottom of the first U-shaped plate 211, and a connecting plate 213 connected to the bottom of the first U-shaped plate 211 and located on both sides of the second U-shaped plate 212. The opening of the first U-shaped plate 211 and the opening of the second U-shaped plate 212 form the through groove 23. The light-shielding plate 22 is connected to the top of the first U-shaped plate 211. A side-open U-shaped groove 214 is formed between the second U-shaped plate 212 and the connecting plate 213, and is movably connected to the light-shielding groove 1 through the U-shaped groove 214.
[0030] Specifically, through the cooperation of the first U-shaped plate 211 and the second U-shaped plate 212, the openings of the first U-shaped plate 211 and the second U-shaped plate 212 form a through groove 23 that cooperates with the light-blocking groove 1. Furthermore, the cooperation of the second U-shaped plate 212 and the connecting plate 213 forms a U-shaped groove 214 with one side open. The connector 21 can be movably connected to the light-blocking groove 1 through the U-shaped groove 214, thereby allowing the connector 21 to adjust its position along the length of the light-blocking groove 1. Since the side of the light-blocking groove 1 away from the curtain fabric 6 is in contact with the inner side of the external curtain shell 4, one side of the U-shaped groove 214 is set to be open, so that the movement of the connector 21 will not be affected by the contact between the light-blocking groove 1 and the inner side of the external curtain shell 4.
[0031] Preferably, the first U-shaped plate 211 and the light-shielding plate 22 are integrally formed. Integral forming can reduce the number of parts required in the assembly process, thereby reducing assembly time and cost. Since the integrally formed parts are a whole, the connection points between parts can be reduced, improving stability and reliability.
[0032] Example 2
[0033] refer to Figure 6 The light-blocking component 2 is a vertically arranged plate 3, which is connected to one or both sides of the light-blocking groove 1. Unlike embodiment 1, the light-blocking component 2 is a vertically arranged plate 3, and the plate 3 can be connected to one or both sides of the light-blocking groove 1. However, in this embodiment, based on cost and light-blocking performance, it is chosen to be connected to one side of the light-blocking groove 1. Moreover, to ensure aesthetics, the plate 3 is located on the back side of the curtain fabric 6.
[0034] Preferably, the free end of the plate 3 extends away from the curtain fabric 6. The plate 3 and the light-blocking groove 1 are integrally formed. The structure of the plate 3 is the same as the function of the light-blocking plate 22 in Embodiment 1, so it will not be described in detail here. Although the installation is convenient by setting the integrally formed plate 3 on the light-blocking groove 1, the position cannot be adjusted. Therefore, the method used in this embodiment requires ensuring that the top of the light-blocking groove 1 contacts the bottom of the curtain shell 4, and the dimensions need to be accurate.
[0035] Example 3
[0036] refer to Figure 7 and Figure 8 A curtain includes a housing 4 connected to a wall 8, light-blocking grooves 1 symmetrically arranged below the housing 4, a roller 5 connected inside the housing 4, curtain fabric 6 wound on the roller 5, and a drive mechanism 7 for driving the roller 5 to rotate. It also includes a curtain light-blocking assembly 2 as described above, wherein the curtain fabric 6 is embedded in the light-blocking grooves 1, the light-blocking assembly 2 extends towards the end of the roller 5, and the drive mechanism 7 is a drive motor or a pull cord.
[0037] Under this design, during installation, the outer casing 4 needs to be installed on the wall 8 first, then the roller 5 and the drive mechanism 7 are installed on the outer casing 4, and finally the light-blocking groove 1 is installed on the wall 8. The two sides of the curtain fabric 6 are then embedded in the light-blocking groove 1. Under the action of the light-blocking component 2, the gap between the drive mechanism 7 at the end of the roller 5 and the light-blocking groove 1 can be filled well, thus improving the light-blocking effect.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
