Description

Technical Field

[0001] This utility model relates to the field of window sash shading technology, specifically, to an adjustable window sash shading component. Background Technology

[0002] Brackets play a crucial role in supporting and fixing numerous mechanical structures and engineering facilities, and welding is the primary process for firmly connecting their various components. During welding, the appropriate welding method must be selected based on the bracket material (such as carbon steel, stainless steel, etc.). For example, manual arc welding is suitable for various scenarios, while gas shielded welding can achieve a superior weld appearance and performance. Simultaneously, welding parameters, including current, voltage, and welding speed, must be strictly controlled to ensure weld quality and avoid defects such as porosity and cracks. Welding positioning is a critical step in ensuring the welding accuracy of the bracket. By designing reasonable positioning fixtures and utilizing components such as positioning pins and stops, the relative positions between components can be accurately determined, ensuring that the bracket assembly dimensions meet design requirements before welding. Positioning fixtures also improve welding efficiency, reduce the time spent on repeated manual adjustments, and ensure the consistency of brackets in mass production. Precise welding positioning is the foundation for obtaining high-quality bracket welds and is of great significance for improving the overall product performance and reliability. However, how to quickly turn the bracket according to the welding surface and how to improve the stability of bracket welding positioning are currently urgent problems to be solved.

[0003] A search revealed that CN221879263U discloses a top-hung window with shading louvers, comprising a window frame main assembly and a glass sash driving assembly. The top end of the glass sash driving assembly is movably mounted on the window frame main assembly. The glass sash driving assembly is made of double-glazed glass, and a shading louver opening and closing assembly is installed inside the double-glazed glass. The glass sash driving assembly also has a control component for controlling the movement of the shading louver opening and closing assembly. The advantages of this invention are: the glass sash has built-in louvers, which provide shading without affecting ventilation, saves space, and is convenient to use.

[0004] The problem with the above-mentioned top-hung window with blackout louvers is that: 1. This design uses a magnetic base-metal block adsorption method, sliding on the outside of the glass to control the internal Venetian blinds. This is a manual, open-loop control method, which cannot precisely control the opening angle of the blinds and relies entirely on the user's feel. Over time, the magnetic force may weaken, leading to control failure.

[0005] Second, the Venetian blinds in this design lack an effective mechanical locking mechanism after being adjusted to a certain position. When subjected to wind, vibration, or the impact of opening and closing the window sash, the position of the Venetian blinds is easily changed, making it impossible to stably maintain the expected light-blocking or light-transmitting state, requiring frequent readjustment by the user. Utility Model Content

[0006] This utility model proposes an adjustable sunshade component for window sashes, which solves the problems of existing technologies where the adjustment method relies on external magnetic force, which is inconvenient to operate and has low precision and reliability, and where the louvers are fixed in state, have no self-locking function, and are easily affected by external forces.

[0007] The technical solution of this utility model is as follows: an adjustable window sash sunshade component, including a main component, the main component including a window sash body and a slide rail seat fixedly connected to the bottom of the window sash body; The slope formed on the front of the slide rail seat; A drive assembly disposed inside the window sash body; A sliding locking assembly is disposed inside the slide rail seat; The sliding locking assembly includes a slide that can slide horizontally as the drive assembly operates; A sunshade opening and closing assembly is provided at equal intervals in the upper part of the window sash body and can slide and rotate with the slide block to lock in order to complete the opening and closing of the sunshade.

[0008] Preferably, the driving component further includes: A support frame that is symmetrically and fixedly connected to the inside of the window sash body; A positive and negative motor is fixedly installed on the outside of a set of support frames.

[0009] Preferably, the driving component further includes: A first rotating shaft is rotatably connected in the middle of the two sets of support frames; The first rotating shaft is fixedly connected to the output end of the forward and reverse motors; A worm gear is fixedly connected to the outside of the first rotating shaft.

[0010] Preferably, the driving component further includes: A second pivot is rotatably connected to the inner side of the window sash body; A worm gear fixedly connected to the outside of the second rotating shaft; The worm gear is in contact with the worm and is connected in a meshing rotational manner.

[0011] Preferably, the sliding locking assembly further includes: Rotate the threaded rod connected to the inside of the slide rail seat; One end of the threaded rod is fixedly connected to the second rotating shaft; The threaded rod is threaded onto the inside of the slide.

[0012] Preferably, the sliding locking assembly further includes: The tooth grooves are evenly distributed on the side of the slide.

[0013] Preferably, the sunshade opening and closing assembly includes: Couplings that are rotatably connected at equal intervals to the inside of the window sash body; Each coupling corresponds to the position of each gear set.

[0014] Preferably, the sunshade opening and closing assembly further includes: A toothed column fixedly connected to the lower outer side of each of the couplings; Each of the toothed columns corresponds to the position of each toothed groove group and is in meshing contact connection.

[0015] Preferably, the sunshade opening and closing assembly further includes: Sunshade window slats are fixedly connected to the outside of each of the aforementioned couplings.

[0016] Preferably, the sunshade opening and closing assembly further includes: Rubber pads are distributed on the sides of each of the aforementioned sunshade window slats; The rubber pads on the sides of the two adjacent sets of sunshade window slats are in contact.

[0017] The beneficial effects of this utility model are as follows: Improvement 1: Adopting a closed-loop transmission system driven by an electric motor to achieve precise, electric, and integrated adjustment. This patented solution: This patent designs a precision mechanical transmission chain consisting of a forward and reverse motor -> worm gear -> threaded rod.

[0018] Innovation advantages: Electrification and integration: Users can precisely adjust the shading status by controlling the motor, which is convenient and labor-saving. All drive components are integrated inside the window sash body, resulting in a simple appearance that does not compromise the overall integrity of the window.

[0019] Precise and controllable: The rotation of the motor is converted into linear displacement through the screw and nut mechanism and the slide. The amount of displacement is strictly proportional to the number of motor revolutions, so the stroke of the slide can be precisely controlled, and thus the rotation angle of each sunshade slat can be precisely controlled, achieving stepless adjustment from fully open to fully closed.

[0020] Improvement point two: Design a double mechanical self-locking structure to ensure stable and reliable shading. This patented solution cleverly utilizes the inherent characteristics of the transmission system to achieve dual self-locking: The first layer of self-locking worm gear: Utilizing the inherent reverse self-locking characteristic of the worm gear transmission pair, that is, only the worm can drive the worm wheel, and the worm wheel cannot drive the worm in the reverse direction, it effectively locks the power source at the motor input end and prevents it from reversing.

[0021] The second self-locking threaded rod: The screw and nut mechanism formed by the threaded rod and the slide also has good self-locking properties. Especially under static conditions, without a huge external force, it is impossible to push the slide to move and drive the threaded rod to rotate.

[0022] Innovation advantages: Superior anti-interference capability: These two self-locking mechanisms ensure that once the motor stops working, the entire system (from the motor to the sunshade blades) is firmly locked in its current position. Neither wind, vibration, nor accidental impact can easily alter the opening angle of the sunshade blades, resulting in excellent stability.

[0023] Safe and reliable: The mechanical self-locking mechanism does not rely on electricity, and the shading state remains unchanged even when the power is off. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] For examples, please refer to Figures 1-4 The present invention provides a technical solution: an adjustable window sash sunshade component, including a main component 1, the main component 1 including a window sash body 11, and a slide rail seat 12 fixedly connected to the bottom of the window sash body 11. A slope 121 is formed on the front of the slide rail seat 12; A drive assembly 2 is installed inside the window sash body 11; A sliding locking assembly 3 is provided inside the slide rail seat 12; The sliding locking assembly 3 includes a slide 32 that can slide horizontally as the drive assembly 2 operates; A shading opening and closing component 4 is provided at equal intervals in the upper part of the window sash body 11 and can slide and rotate with the slide block 32 to lock in order to complete the shading opening and closing. This design achieves electric, precise control and stable maintenance of the opening and closing angle of the sunshade window slats through the coordinated action of the drive component, the sliding locking component and the sunshade opening and closing component.

[0028] Driver component 2 also includes: A support frame 21 is symmetrically and fixedly connected to the inside of the window sash body 11; A forward and reverse motor 22 is fixedly installed on the outside of a set of support frames 21.

[0029] Driver component 2 also includes: The first rotating shaft 23 is rotatably connected to the middle of the two sets of support frames 21; The first rotating shaft 23 is fixedly connected to the output end of the forward and reverse motor 22; The worm gear 231 is fixedly connected to the outside of the first rotating shaft 23.

[0030] Driver component 2 also includes: The second pivot 24 is rotatably connected to the inner side of the window sash body 11; A worm gear 241 is fixedly connected to the outside of the second rotating shaft 24; The worm gear 241 is in contact with the worm 231 and is in a meshing rotational connection.

[0031] Through the above-mentioned worm gear transmission design, not only is power transmission achieved, but also, due to its inherent transmission characteristics, it plays the role of first-stage speed reduction and torque increase and reverse self-locking, making the system run smoothly and able to resist unexpected reversal caused by external forces.

[0032] The sliding locking component 3 also includes: Rotary connection of threaded rod 31 to the inner side of slide rail seat 12; One end of the threaded rod 31 is fixedly connected to the second rotating shaft 24; The threaded rod 31 is threadedly connected to the inside of the slide 32.

[0033] The threaded transmission mechanism converts the rotational motion of the second shaft 24 into the precise linear motion of the slide 32. It also has good self-locking performance, forming a double guarantee with the aforementioned worm gear self-locking, thus constituting the second-level locking mechanism of the system.

[0034] The sliding locking component 3 also includes: The tooth groove group 321 is evenly distributed on the side of the slide 32.

[0035] The sunshade opening and closing component 4 includes: Couplings 41 are rotatably connected to the inner side of the window sash body 11 at equal intervals; Each coupling 41 corresponds to each gear set 321.

[0036] The sunshade opening and closing assembly 4 also includes: A gear post 411 is fixedly connected to the lower outer side of each coupling 41; Each tooth post 411 is positioned corresponding to each tooth groove group 321 and is in meshing contact connection.

[0037] The meshing design of the toothed groove and toothed column synchronously and equidistantly converts the horizontal linear displacement of the slide 32 into the rotational motion of all couplings 41, ensuring the uniformity and consistency of the movement of all sunshade window slats 42, and avoiding interference or light leakage caused by asynchrony.

[0038] The sunshade opening and closing assembly 4 also includes: Sunshade window slats 42 are fixedly connected to the outside of each coupling 41.

[0039] The sunshade opening and closing assembly 4 also includes: Rubber pads 421 are distributed on the sides of each sunshade window slat 42; The rubber pads 421 on the sides of two adjacent sets of sunshade window slats 42 are in contact; The design of the rubber pad 421 allows it to be squeezed together to form a soft seal when the sunshade window slats 42 are closed, effectively reducing light penetration from the gaps between the slats and improving the shading effect. It also plays a role in shock absorption and noise reduction.

[0040] When it is necessary to shade the window sash body 11, the forward and reverse motor 22 can be started. The motor drives the first rotating shaft 23 and the worm gear 231 to rotate, and after being meshed and transmitted by the worm wheel 241, it drives the second rotating shaft 24 to rotate. The second rotating shaft 24 drives the threaded rod 31 to rotate synchronously, forcing the slide block 32, which is threaded with it, to slide horizontally along the inner side of the slide rail seat 12.

[0041] The benefits of this drive process are: it enables centralized drive of a single motor to control the synchronous and precise movement of all sunshade slats, making operation simple and convenient, and avoiding the control complexity and increased costs associated with multiple drive sources.

[0042] When the slide block 32 slides, the toothed groove group 321 on its side meshes with the toothed column 411 fixed to the lower part of each coupling 41. The toothed column 411 drives the coupling 41 to rotate, and finally the sunshade window slat 42 fixed on the coupling 41 rotates accordingly. When the sunshade window slat 42 rotates to a horizontal state inside the window sash body 11, the slats overlap each other to complete the sunshade closure.

[0043] The beneficial effects of this transmission process are: through simple mechanical meshing, a linear motion source is reliably converted into multiple rotary motion outputs, ensuring absolute synchronization of all blade angles and realizing linear stepless adjustment of the shading area, allowing users to precisely control the amount of light entering the room as needed.

[0044] In particular, the meshing transmission pair of worm 231 and worm wheel 241, and the threaded transmission pair of threaded rod 31 and slide 32 used in this design, all have natural dual mechanical self-locking characteristics.

[0045] The core benefit of this dual self-locking design is that the entire transmission system is firmly locked once the motor stops supplying power. The angle of the sunshade slats is strictly fixed and will not change due to wind, window vibration, or accidental contact, greatly improving the long-term stability and reliability of the sunshade state and reducing maintenance requirements.

[0046] Specifically, this design features a slope 121 on the front of the slide rail seat 12.

[0047] The beneficial effects of this structure are: guiding rainwater or condensate to flow away along the slope, preventing liquid from accumulating on the surface of the slide rail seat 12 or in the mating gap with the slide seat 32, effectively preventing problems such as corrosion, freezing or increased movement resistance caused by water accumulation, and improving the durability and reliability of the components in humid environments.

[0048] Specifically, this design includes rubber pads 421 on the sides of each sunshade window slat 42.

[0049] The beneficial effects of this design are: when the sunshade slats 42 are closed, the rubber pads 421 are squeezed and deformed, which not only effectively seals the gaps between the slats and enhances the light-blocking airtightness, but also avoids the noise and wear caused by direct collision of hard slats due to their soft contact characteristics, thus improving the user experience and lifespan of the product.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
