Description

Technical Field

[0001] This utility model belongs to the field of building shading technology, and in particular relates to a building shading device based on environmental adaptive adjustment. Background Technology

[0002] Architectural shading refers to the use of various design and technical means to reduce the amount of direct solar radiation entering a building, thereby lowering indoor temperature, improving comfort, and saving energy.

[0003] A conventional patent, CN214532706U, discloses a building shading device, which includes a drive device mounted on a steel structure column and a shading device. The shading device includes two sets of slide rails fixedly mounted on the steel structure column, several rollers slidably mounted within the slide rails, and several sets of shading components positioned between adjacent rollers. The shading components are foldable and are driven by the drive device to slide the rollers upwards along the slide rails, folding together. Each shading component includes a first connecting rod hinged to the rollers and a second connecting rod hinged to the end of the first connecting rod away from the rollers. A curtain is fixedly mounted on the first and second connecting rods. This application has the effect of folding and storing the curtain, reducing the space occupied by the shading components.

[0004] However, existing technologies have some problems: traditional devices only have a light-blocking effect, blocking sunlight when it is too strong, which will reduce the indoor light intensity and thus reduce indoor visibility. If a device with good light transmission is selected, it cannot meet the required conditions when viewing a projector lamp in an environment that requires low light intensity. Therefore, we propose an environmentally adaptive building shading device. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a building shading device based on environmental adaptive adjustment.

[0006] This utility model is implemented as follows: a building sunshade device based on environmental adaptive adjustment includes an upper shell and a lower shell for fixing to a wall. Two lower shells are provided, fixed to the lower sides of the upper shell. A plurality of curtain slats are rotatably installed between the two lower shells. A flipping assembly is fixedly installed inside the lower shell. The flipping assembly includes a toothed plate, which is slidably installed inside the lower shell.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown in the figure, the present invention provides an environmentally adaptive building shading device, including an upper shell 1 and a lower shell 2 for fixing to a wall. There are two lower shells 2, which are fixed to the lower parts of both sides of the upper shell 1. A plurality of curtain slats 3 are rotatably installed between the two lower shells 2. A flipping assembly 5 is fixedly installed inside the lower shell 2. The flipping assembly 5 includes a toothed plate 503, which is slidably installed inside the lower shell 2. The toothed plate 503 is meshed with a right angle gear 504. A groove is opened on one side of the right angle gear 504. A slider 505 is slidably connected inside the groove of the gear. A rotating rod 506 is fixedly connected to the end of the slider 505 away from the gear. A clamping plate 508 is fixedly connected to the end of the rotating rod 506 away from the slider 505 through the lower shell 2. The curtain slats 3 are clamped and installed inside the two clamping plates 508. The curtain slats 3 are driven by the toothed plate 503 to perform angle adjustment.

[0025] The aforementioned building shading device based on environmental adaptive adjustment has a lower housing 2 located on both sides of an upper housing 1, with multiple rotatable curtain slats 3 installed between the two lower housings 2. Each curtain slat 3 is fixed by a clamping plate 508, which is driven by a rotating rod 506. The rotating rod 506 is connected to a toothed plate 503 via a slider 505, and the toothed plate 503 controls the rotation angle of the curtain slat 3 by meshing with a right-angle gear 504. The sliding of the toothed plate 503 changes the angle of the curtain slat 3, and when the toothed plate 503 moves, it drives the right-angle gear 504 to rotate, thereby adjusting the curtain slat 3 to different angles. The flipping assembly 5 contains a drive unit that can work with a photosensitive unit for adaptive adjustment. The photosensitive unit can detect the ambient light intensity and feed the data back to the drive unit. According to preset light conditions, the drive unit adjusts the position of the toothed plate 503, thereby automatically adjusting the angle of the curtain slat 3.

[0026] Full shading mode: When the photosensitive unit detects that the outdoor light intensity is too strong, the drive unit is activated, pushing the toothed plate 503 to rotate the curtain 3 to the angle that completely blocks the sunlight, which is suitable for projection or low-light scenarios.

[0027] Partial shading mode: When the light is moderate and natural light is needed but direct sunlight is not desired, the slat angle 3 will automatically adjust to partial shading mode.

[0028] Maximum Lighting Mode: When sunlight needs to be maximized, the curtain slats are adjusted to angle 3 to be parallel to the light source, ensuring that the room receives as much sunlight as possible.

[0029] The photosensitive unit automatically detects ambient light and adjusts the angle of the curtain slats 3 according to the light intensity, eliminating the need for manual operation and greatly improving ease of use. The curtain slats 3 can intelligently manage sunlight through precise angle adjustment, avoiding the problem of traditional shading devices that only provide light blocking and cause reduced indoor visibility under strong light conditions. The device can flexibly adjust according to light requirements, ensuring shading effectiveness without affecting indoor lighting.

[0030] In this embodiment, a connecting rod 511 is fixedly connected between adjacent toothed plates 503, and multiple toothed plates 503 cooperate with multiple connecting rods 511 to perform synchronous angle adjustment actions on multiple curtain slats 3. An electric actuator 501 is fixedly installed on the upper part of the lower housing 2, and a linkage plate 502 is fixedly connected to the lower part of the electric actuator 501. The lower part of the linkage plate 502 is fixedly connected to the toothed plate 503 located at the top.

[0031] When the electric actuator 501 receives a control signal, it extends and retracts vertically, pushing the linkage plate 502 up and down. The lower part of the linkage plate 502 is fixedly connected to the uppermost toothed plate 503, so when the electric actuator 501 pushes the linkage plate 502 to move, the uppermost toothed plate 503 also moves up and down. Adjacent toothed plates 503 are fixedly connected by a connecting rod 511. When the uppermost toothed plate 503 moves, the connecting rod 511 transmits force, causing all toothed plates 503 to move synchronously. The synchronous movement of multiple toothed plates 503 causes their meshing gears to rotate simultaneously, thereby driving the connected curtain slats 3 to perform synchronous angle adjustment. With the movement of the electric actuator 501, the displacement of the toothed plates 503 is transmitted to the rotating rod 506 that holds the curtain slats 3 through the gears. The rotating rod 506 rotates under the push of the toothed plates 503, driving the curtain slats 3 to adjust their angle, thus achieving precise control of light.

[0032] In this embodiment, a sliding plate 507 corresponding to the number of curtain slats 3 is also slidably installed inside the lower housing 2. A rotating rod 506 is rotatably installed inside the sliding plate 507. A thread 509 is opened inside the sliding plate 507. The same screw 405 is screwed into each sliding plate 507. The screw 405 is rotatably installed inside the upper housing 1. The curtain slats 3 are controlled by the screw 405 to move up and down.

[0033] The screw 405 is fixedly installed inside the upper housing 1. Through rotation, the screw 405 can rotate along its length. The screw 405 is threaded to the slide plate 507 via a thread 509. When the screw 405 rotates, it drives the slide plate 507 to move up and down along the direction of the screw 405. Each slide plate 507 has a rotating rod 506 installed inside, which is connected to the slat 3. When the screw 405 rotates, the thread 509 causes the slide plate 507 to slide up and down, and the rotating rod 506 moves accordingly, driving the connected slat 3 to achieve up and down movement. Since the screw 405 controls multiple slide plates 507 simultaneously, and the number of slide plates 507 corresponds to the number of slats 3, when the screw 405 rotates, all slide plates 507 move synchronously, achieving synchronous up and down movement of all slats 3.

[0034] In this embodiment, the upper part of the upper housing 1 is also provided with a drive assembly 4, which includes a motor 401. The motor 401 is fixedly installed on one side of the upper housing 1. First helical gears 402 are rotatably installed inside the two sides of the upper housing 1 respectively. A linkage rod 404 is fixedly connected between the two first helical gears 402. Second helical gears 403 are also rotatably installed inside the two sides of the upper housing 1. Each first helical gear 402 is meshed with the second helical gear 403. The lower part of the second helical gear 403 is fixedly connected with a screw 405. The curtain slats 3 are driven by the motor 401 to stack and store on the side of the lower housing 2 close to the upper housing 1. The lower housing 2 is provided with a slide rail corresponding to the tooth groove of the right angle gear 504. The slider 505 moves from the slide rail to the groove of the designated gear.

[0035] The drive assembly 4 is driven by a motor 401. The motor 401 is fixedly mounted on one side of the upper housing 1, and power is output through the rotation of the motor 401. First helical gears 402 are installed inside both sides of the upper housing 1. When the motor 401 starts, it drives the linkage rod 404 to rotate. The linkage rod 404 is connected to the first helical gears 402 on both sides to ensure that the first helical gears 402 on both sides rotate synchronously.

[0036] Each first helical gear 402 meshes with a second helical gear 403 inside both sides of the upper housing 1. When the first helical gear 402 rotates, it drives the second helical gear 403 to rotate synchronously. The lower part of the second helical gear 403 is fixedly connected to a screw 405, so as the second helical gear 403 rotates, the screw 405 also begins to rotate.

[0037] The rotation of the screw 405 causes the slide plate 507, which is screwed to it, to move up and down along the direction of the screw 405. A slider 505 is fixedly connected to the slide plate 507, and the slider 505 has a corresponding slide rail in the lower housing 2. As the screw 405 rotates, the slide plate 507 drives the slider 505 to slide within the slide rail.

[0038] The slide rail is designed with a path corresponding to the tooth groove of the right-angle gear 504. When the slider 505 moves to a specific position in the slide rail, it enters the tooth groove of the right-angle gear 504. At this time, the slider 505 moves from the slide rail to the groove of the designated gear, forming an engaged state. Once the slider 505 enters the tooth groove of the right-angle gear 504, the motor 401 continues to drive the screw 405 to rotate while the right-angle gear 504 begins to rotate. The rotation of the gear drives the curtain slat 3 to rotate through the meshing toothed plate 503, thereby adjusting the angle of the curtain slat 3.

[0039] In this embodiment, a spring clip 6 is also fixedly installed inside the upper housing 1. A baffle 7 is fixedly connected to the output end of the spring clip 6. In the initial state, the baffle 7 is located at the bottommost slide plate 507 and its adjacent slide plate 507 respectively. The bottommost slide plate 507 is screwed to the upper part of the screw 405. The adjacent slide plate 507 of the bottommost slide plate 507 is slidably connected to the screw 405. A traction rope 510 is fixedly connected between the two adjacent slide plates 507.

[0040] A spring clip 6 is fixedly installed inside the upper housing 1, and the spring clip 6 is connected to the baffle 7 through elastic action. In the initial state, the baffle 7 is located between the lowest slide plate 507 and its adjacent slide plate 507, which serves as an initial limit. At this time, the lowest slide plate 507 is screwed to the screw 405, while the adjacent slide plate 507 is in a sliding connection with the screw 405.

[0041] When the curtain slat 3 needs to be unfolded, the lowest slide plate 507 moves downwards along with its adjacent slide plates 507 via the traction rope 510. At this time, the spring clip 6 and the baffle 7 ensure that each slide plate 507 is screwed onto the screw 405 layer by layer, maintaining an equidistant distribution between the slide plates 507. This ensures that the curtain slat 3 can unfold layer by layer with sufficient space for rotation. Specifically, each slide plate 507, under the action of the screw 405, moves sequentially to the position without threads 509 and contacts the screw 405 layer by layer through the pushing action of the traction rope 510. Adjacent slide plates 507 are limited and controlled by the spring clip 6 and the baffle 7, ensuring that each slide plate 507 is screwed onto the screw 405 at the appropriate time.

[0042] During storage, driven by screw 405, the bottom slide plate 507 begins to move upward. When the bottom slide plate 507 moves to the part of screw 405 without threads 509, due to the limiting effect of baffle 7, the bottom slide plate 507 is pushed out of the sliding position, and the slide plate 507 is unscrewed from the threads 509 of screw 405. At this time, the slide plate 507 moves into the space of the storage curtain 3. As the bottom slide plate 507 enters the storage space, the next adjacent slide plate 507 is pushed up by the traction rope 510 and screwed into screw 405. The traction rope 510 connects two adjacent slide plates 507, so when one slide plate 507 moves upward, the traction rope 510 pulls the next slide plate 507 to keep them moving synchronously. Storage is complete.

[0043] The working principle of this utility model:

[0044] In use, the toothed plate 503 controls the rotation angle of the curtain slat 3 by meshing with the right-angle gear 504. The sliding of the toothed plate 503 changes the angle of the curtain slat 3; when the toothed plate 503 moves, it drives the right-angle gear 504 to rotate, thus adjusting the curtain slat 3 to different angles. The flipping assembly 5 contains a photosensitive unit and a drive unit. The photosensitive unit detects the ambient light intensity and feeds the data back to the drive unit. Based on preset lighting conditions, the drive unit adjusts the position of the toothed plate 503, thereby automatically adjusting the angle of the curtain slat 3.
