Description

Technical Field

[0001] This invention relates to the field of partition wall technology, specifically to a partition wall structure with adjustable light transmittance. Background Technology

[0002] Adjustable light transmittance glass partitions are widely used in offices, homes, and commercial spaces, offering multiple advantages such as space division, lighting adjustment, privacy protection, and aesthetic appeal. Compared to traditional fixed partitions, they allow for flexible adjustment of light transmittance based on ambient light levels and usage requirements, making them more adaptable and practical. Currently, most mainstream adjustable light transmittance partitions utilize double-glazed glass with built-in louvers. The louver angle is controlled manually via magnetic adjustment, altering the light-transmitting area and thus adjusting the light transmittance. Due to their simple structure, convenient operation, lack of exposed transmission components, and excellent sealing, they have been widely adopted.

[0003] Existing glass partition walls with dimming louvers generally employ a magnetic manual adjustment structure. This involves the magnetic coupling of inner and outer magnets, allowing the rotation of an external handle to rotate the inner louver blades, thereby adjusting the wall's light transmittance. However, current dimming partition wall technologies typically use a single magnet for single-point attraction and coupling, resulting in poor resistance to displacement during rotation. The inner and outer magnets are prone to relative slippage, leading to idle travel during handle rotation and lag in blade rotation angle. Summary of the Invention

[0004] The purpose of this invention is to provide a partition wall structure with adjustable light transmittance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a partition wall structure with adjustable light transmittance, comprising: The frame consists of two horizontal beams and two vertical beams forming a rectangular frame. Glass panels are mounted on the front and back sides of the frame, and the glass panels and the frame together form a hollow cavity. The vertical beams are hollow cavity structures. The louvers are arranged inside the cavity and the light transmittance of the partition wall is adjusted by changing the deflection angle of the louvers. An adjustment mechanism, installed in the middle of one of the vertical beams, includes an inner magnetic unit, an outer magnetic unit, and a transmission unit. The inner magnetic unit has a first turntable, and the outer magnetic unit has a second turntable. The first and second turntables are located on opposite sides of the cavity of the vertical beam, facing each other. Multiple inner and outer magnetic strips are embedded on the opposite end faces of the first and second turntables. The inner magnetic strips are arranged in a circular array along the end face of the first turntable. Each outer magnetic strip corresponds to one of the inner magnetic strips, with the paired outer and inner magnetic strips having opposite magnetic poles. The vertical beam is rotated... The second turntable on the outer side can synchronously drive the first turntable on the inner side of the vertical beam to rotate through magnetic attraction. The exposed magnetic poles of the adjacent inner magnetic strips are arranged alternately. When the rotation of the first turntable is slightly misaligned, the adjacent outer magnetic strips and inner magnetic strips corresponding to the misalignment position will form a composite corrective torque of opposite pole attraction and like pole repulsion, which automatically corrects the relative offset of the inner and outer magnetic units and continuously constrains the first and second turntables to rotate synchronously. The transmission unit is connected between the first turntable and the louvers and is used to transmit the rotational power of the first turntable to the louvers to drive the louver blades to flip and adjust the angle.

[0006] As a further preferred embodiment of this technical solution, the transmission unit includes a transmission shaft, a first helical gear, and a second helical gear. The transmission shaft is disposed inside the cavity of the vertical beam, with one end rotatably connected to the inner wall of the cavity of the vertical beam and the other end fixedly connected to the shaft end of one blade of the louver. The first helical gear is fixedly sleeved on the transmission shaft, and the second helical gear meshes with the first helical gear, with its shaft end fixedly connected to the shaft end of the first turntable.

[0007] As a further preferred embodiment of this technical solution, the inner magnetic unit further includes a first housing, which is fixedly disposed on the inner wall of the vertical beam cavity. A first cavity and a second cavity are sequentially formed inside the first housing along the direction away from the outer magnetic unit. The first turntable is disposed at the axis of the first cavity. The first rotating disk, the rotating plate, and the second helical gear are coaxially disposed. The axes of the first rotating disk, the rotating plate, and the second helical gear are fixedly connected by a connecting shaft.

[0008] As a further preferred embodiment of this technical solution, a first bearing is provided at the annular gap between the first turntable and the first cavity, and a rotating plate is provided inside the second cavity. The rotating plate is a circular plate and is adapted to the second cavity.

[0009] As a further preferred embodiment of this technical solution, the external magnetic unit further includes a second housing, which is fixedly mounted on the outer wall of the vertical beam. The interior of the second housing has a third cavity and a fourth cavity sequentially opened in the direction away from the internal magnetic unit. The second turntable is located in the third cavity, and a positioning plate is provided in the fourth cavity. An adjustment plate is provided at the end of the second housing. The second turntable, the positioning plate, and the adjustment plate are coaxially arranged, and the axis of the second turntable, the positioning plate, and the adjustment plate are fixedly connected by a connecting shaft.

[0010] As a further preferred embodiment of this technical solution, a second bearing is provided at the annular gap between the second turntable and the third cavity, the positioning plate is a circular plate, and the positioning plate is adapted to the fourth cavity.

[0011] As a further preferred embodiment of this technical solution, the annular inner wall of the fourth cavity is provided with a plurality of slots, which are arranged in a ring array, and the annular outer wall of the second turntable is provided with ball bearings.

[0012] As a further preferred embodiment of this technical solution, a radial groove is formed inside the second turntable, and a connecting hole is formed between the annular outer wall of the second turntable and the groove. A mounting seat is slidably provided in the groove, and a spring is fixedly provided at the bottom of the groove and one end of the mounting seat. A spherical groove is formed at the other end of the mounting seat, and the ball is rotatably disposed in the spherical groove. The exposed end of the ball extends out of the groove and inserts into the slot, and the slot and the exposed end of the ball are mutually adapted.

[0013] This invention provides a partition wall structure with adjustable light transmittance, which has the following beneficial effects: This invention features an inner magnetic strip arranged in a ring array with alternating positive and negative magnetic poles on the end face of the first turntable. These inner magnetic strips are magnetically paired with the outer magnetic strips one by one. Compared to the traditional single-point magnetic attraction structure, this creates a bidirectional composite correction torque of opposite pole adsorption and like pole repulsion. This automatically corrects the rotational offset of the inner and outer turntables, solving the problems of handle free travel, blade angle lag, and magnet slippage that exist in traditional magnetic attraction adjustment. This effectively ensures the accuracy of louver blade angle adjustment and improves the synchronization and stability of dimming operation. At the same time, the combination of ball bearings, springs, and annular grooves forms a damping gear locking structure, which can adaptively limit and decelerate the rotation speed of the adjustment plate. This avoids the defect of the magnetic pole correction structure not responding in time due to excessively fast adjustment. It can achieve precise segmented positioning of light transmittance and can stably lock the blade angle after adjustment, preventing the blade from spontaneously deflecting due to gravity and airflow, thus ensuring a constant light transmittance of the partition wall.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides a technical solution: such as Figure 1 As shown in this embodiment, an adjustable light transmittance partition wall structure includes: a frame 100, louvers 200, and an adjustment mechanism 300. The frame 100 is a rectangular frame formed by two horizontal beams 110 and two vertical beams 120. Glass panels are mounted on the front and back sides of the frame 100, forming a hollow cavity with the glass panels. The vertical beams 120 are hollow cavity structures. The louvers 200 are arranged inside the cavities. The light transmittance of the partition wall is adjusted by changing the deflection angle of the louvers. The louvers 200 are a conventional technology, and their working principle is not described in detail. The louvers 200 can freely rotate within a range of 0° to 90°. When the louvers are fully closed, they can achieve complete shading; when the louvers are fully open, they can maximize light transmission; and when the louvers are at an intermediate angle, they achieve a semi-transparent state. By changing the deflection angle of the louvers, the light penetration area is changed, thereby adjusting the overall light transmittance of the partition wall to adapt to different lighting and privacy protection needs. The adjustment mechanism 300 is installed in the middle of one of the vertical beams 120. Figure 3As shown, it includes an inner magnetic unit 310, an outer magnetic unit 320, and a transmission unit 330, as follows: Figure 4 As shown, the inner magnetic unit 310 is provided with a first turntable 313, and the outer magnetic unit 320 is provided with a second turntable 323. The first turntable 313 and the second turntable 323 are respectively located on the inner and outer sides of the cavity of the vertical beam 120 and face each other. Multiple inner magnetic strips 314 and outer magnetic strips 329 are respectively embedded on the opposite end faces of the first turntable 313 and the second turntable 323. The inner magnetic strips 314 are arranged in a circular array along the end face of the first turntable 313. Each outer magnetic strip 329 is arranged in a one-to-one correspondence with the inner magnetic strip 314. The magnetic poles of the paired outer magnetic strips 329 and the inner magnetic strips 314 are opposite. Rotating the second turntable 323 on the outer side of the vertical beam 120 can synchronously drive it through magnetic attraction. The first turntable 313 inside the vertical beam 120 rotates, and the exposed magnetic poles of the adjacent inner magnetic strips 314 are arranged alternately. When the rotation of the first turntable 313 is slightly misaligned, the adjacent outer magnetic strips 329 and inner magnetic strips 314 at the misaligned position will form a composite corrective torque of opposite pole attraction and like pole repulsion, which automatically corrects the relative offset between the outer magnetic strips 329 and inner magnetic strips 314 and continuously constrains the first turntable 313 and the second turntable 323 to rotate synchronously. The transmission unit 330 is connected between the first turntable 313 and the louver 200 and is used to transmit the rotational power of the first turntable 313 to the louver 200 to drive the louver 200 blades to flip and adjust the angle.

[0018] The ring-shaped alternating positive and negative magnetic pole layout differs from the traditional single-point magnetic attraction structure. When there is a slight deviation in the rotation angle of the inner first turntable 313 relative to the outer second turntable 323, the adjacent magnetic poles in the misaligned area form a bidirectional composite correction torque of "opposite pole attraction and traction, and like pole repulsion and correction", which automatically corrects the offset and always locks the rotation angle of the inner and outer turntables to be consistent, thereby avoiding the slippage, empty travel and rotation angle lag problems of the traditional magnetic attraction structure.

[0019] like Figure 4 As shown, the transmission unit 330 includes a transmission shaft 331, a first helical gear 332, and a second helical gear 333. The transmission shaft 331 is located inside the cavity of the vertical beam 120. One end of the shaft is rotatably connected to the inner wall of the cavity of the vertical beam 120, and the other end is fixedly connected to the shaft end of one blade of the louver 200. The first helical gear 332 is fixedly sleeved on the transmission shaft 331. The second helical gear 333 meshes with the first helical gear 332, and its shaft end is fixedly connected to the shaft end of the first turntable 313. The rotation axis of the inner and outer magnetic turntables is perpendicular to the front-back direction of the glass, while the rotation axis of the louver 200 blades is parallel to the left-right direction of the glass. The two sets of helical gears mesh perpendicularly to each other, which can transmit the horizontal front-back rotation torque of the first turntable 313 by 90° to the transmission shaft 331.

[0020] like Figure 5 and Figure 6As shown, the inner magnetic unit 310 also includes a first housing 311, which serves as a fixed base for the inner magnetic unit 310 and is fixedly mounted on the inner wall of the cavity of the vertical beam 120. A first cavity 3111 and a second cavity 3112 are sequentially formed inside the first housing 311 along a direction away from the outer magnetic unit 320. A first turntable 313 is located at the axis of the first cavity 3111. The first turntable 313, the rotating plate 315, and the second helical gear 333 are coaxially arranged. The two are fixedly connected at the axis by a connecting shaft. A first bearing 312 is provided in the annular gap between the first turntable 313 and the first cavity 3111. The first bearing 312 can greatly reduce the frictional resistance between the first turntable 313 and the housing when rotating. A rotating plate 315 is provided inside the second cavity 3112. The rotating plate 315 is a circular plate. The rotating plate 315 and the second cavity 3112 are adapted to each other and can radially limit the rotation assembly, avoid radial shaking and eccentric offset during the rotation of the turntable, and improve the overall rotational stability and coaxiality.

[0021] like Figure 7 and Figure 8 As shown, the external magnetic unit 320 also includes a second housing 321. The second housing 321 provides an external mounting carrier for the adjustment structure of the external magnetic unit 320 and is fixedly mounted on the outer wall of the vertical beam 120. The interior of the second housing 321 has a third cavity 3211 and a fourth cavity 3212 sequentially formed along the direction away from the inner magnetic unit 310. The second turntable 323 is located in the third cavity 3211, and the fourth cavity 3212 is provided with a positioning plate 324. An adjustment plate 32 is provided at the end of the second housing 321. 5. The second turntable 323, the positioning plate 324, and the adjusting plate 325 are coaxially arranged. The axis of the second turntable 323, the positioning plate 324, and the adjusting plate 325 are fixedly connected by a connecting shaft. When the user rotates the adjusting plate 325, the positioning plate 324 and the second turntable 323 can be rotated synchronously. A second bearing 322 is provided in the annular gap between the second turntable 323 and the third cavity 3211. The positioning plate 324 is a circular plate and is compatible with the fourth cavity 3212.

[0022] When the adjusting plate 325 is rotated, if the rotation speed of the external second turntable 323 is too fast, the misaligned area caused by the "annular alternating positive and negative magnetic pole layout" will form a bidirectional composite corrective torque of "opposite pole attraction and traction, like pole repulsion and correction" between adjacent magnetic poles. This torque cannot promptly correct the slight deviation in the rotation angle of the second turntable 323, resulting in the louver 200 blade adjustment angle not keeping up with the rotation angle of the adjusting plate 325. To avoid this problem, the following design is implemented: Figure 6 As shown, several slots 32121 are formed on the annular inner wall of cavity 3212, and the slots 32121 are arranged in a ring array, such as... Figure 5As shown, a ball bearing 326 is provided on the annular outer wall of the positioning plate 324. A sliding groove 3241 is radially provided inside the positioning plate 324. A connecting hole is provided between the annular outer wall of the positioning plate 324 and the sliding groove 3241. A mounting seat 327 is slidably provided in the sliding groove 3241. A spring 328 is fixedly provided at the bottom of the sliding groove 3241 and one end of the mounting seat 327. A spherical groove 3271 is provided at the other end of the mounting seat 327. The ball bearing 326 is rotatably disposed in the spherical groove 3271. The exposed end of the ball bearing 326 extends out of the sliding groove 3241 and inserts into the slot 32121. The slot 32121 and the exposed end of the ball bearing 326 are mutually adapted.

[0023] The circular array of slots 32121 and balls 326 together form the basic structure for gear positioning. By engaging the balls 326 with different slots 32121, segmented positioning of the adjustment angle can be achieved. Specifically, during rotation adjustment, the side wall of the slot 32121 squeezes the balls 326, pushing the mounting base 327 to compress the spring 328, causing the balls 326 to automatically retract and disengage from the current slot 32121, achieving smooth gear shifting. After rotation stops, the spring 328 rebounds and pushes the balls 326 into the corresponding slot 32121, forming a stable damping lock. This damping lock ensures that the user is forced to slow down when rotating the adjustment plate 325, ensuring that the bidirectional composite correction torque of "opposite pole adsorption traction and like pole repulsion push correction" can promptly correct the slight deviation in the rotation angle of the second turntable 323.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
