Description

Technical Field

[0001] The invention relates to the technical field of blinds, and in particular to a single-side controlled hollow glass built-in blind. Background Art

[0002] Insulating glass built-in blinds refer to windows that are set in a face-to-face state and sealed on all sides with blinds that can be raised and lowered as needed inside two glasses (inner glass and outer glass, also called front glass and rear glass) that are sealed on all sides. They belong to the category of sunshade insulating glass products. There are two types of control modes for insulating glass built-in blinds: one is single-operator control; the other is double-operator control. Single-operator control refers to the cooperation of an outer operator and an inner operator to realize the flipping of the blinds and the lifting of the blinds. Double-operator control refers to the control of the flipping of the blinds and the lifting of the blinds by two inner operators and two outer operators respectively.

[0003] In the related art, application number CN202020992647.8 discloses a venetian blind control device and a hollow glass built-in venetian blind. It includes an integral plug angle of a connecting seat, a flip transmission member rotatably arranged thereon, a flip limiter driven by the flip transmission member, and a flip limiter connecting member driven by the flip limiter, and a lifting rope pulley installed therein. The present invention centrally arranges the driving device of the flip axis in the entire venetian blind in the integral plug angle of the connecting seat above the window body, and drives the flip limiter connecting member to rotate the flip axis of the venetian blind according to the traction of the flip traction rope through the flip limiter.

[0004] However, the above structure still has the following problems:

[0005] 1. The connection between the connecting seat and the plug angle body is respectively provided with a first supporting hole of the transmission wheel shaft, a second supporting hole of the transmission wheel shaft and a supporting hole of the flip shaft fixing column, a flip transmission wheel cavity is formed between the first supporting hole of the transmission wheel shaft and the second supporting hole of the transmission wheel shaft, and a flip limiter cavity is formed between the second supporting hole of the transmission wheel shaft and the supporting hole of the flip shaft fixing column; the connecting seat comprises: a connecting seat body, which is arranged in the middle of the connecting seat; a flip transmission wheel cavity and a flip limiter cavity, which are arranged on the upper part of the connecting seat body and are used to assemble a flip transmission member, a flip limiter of the limiter body and a flip limiter connecting member; during frequent flipping operations, the flip transmission member, the flip limiter of the limiter body and the flip limiter connecting member are easily disengaged from the first supporting hole of the transmission wheel shaft, the second supporting hole of the transmission wheel shaft and the supporting hole of the flip shaft fixing column, which has the disadvantages of poor stability and inconvenient disassembly and assembly.

[0006] 2. The flip limiter can be configured to include a limiter body and a stopper installed on the limiter body: the limiter body is fixed on the outer periphery of the flip transmission member, and the stopper includes a first stopper and a second stopper respectively distributed along the circumferential direction of the limiter body. The limiter body can be specifically configured to be a metal strip wound around the middle of the flip transmission member, and its two ends are fixed to the flip transmission member and configured to protrude radially outward, and the two stoppers can respectively abut on both sides of the stopper block to limit the rotation angle of the flip transmission member. Since the limiter body is configured to be a metal strip wound around the middle of the flip transmission member, there is a disadvantage of being troublesome to disassemble and assemble. In addition, when the stopper of the metal strip is supported by the stopper block, due to the large contact area between the flip transmission member and the metal strip, when the inner and outer operators are used to lift the venetian blind, the flip transmission member needs to overcome a large friction force to rotate relative to the metal strip, which also increases the magnetic attraction force required by the inner and outer operators, and requires a large force to smoothly complete the lifting operation. At the same time, it also causes the inner and outer operators to be provided with more magnetic blocks, which increases the production cost. Summary of the invention

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The transmission mechanism of the present invention uses the design of the corner structure and the flip axis to raise and lower the venetian blinds through the traction mechanism and flip the blades of the venetian blinds through the flip mechanism. The user only needs to operate on one side to achieve the raising and lowering of the venetian blinds and the adjustment of the blade angles, which greatly facilitates the use and improves the user experience. The upper mounting seat and the lower mounting seat are detachably connected, so that the user can easily disassemble the two for maintenance, replacement or cleaning when necessary. At the same time, the second mounting cavity provides a closed installation environment for the flip mechanism, which can effectively prevent the flip mechanism from falling out due to external force or vibration during operation, thereby ensuring the stable operation of the blinds.

[0036] 2. According to the corner structure of the shutter of the present invention, during the actual working process, in the initial state, the paddle partially extends into the accommodating space between two adjacent convex teeth on the flip wheel under the action of the elastic reset member. When the flip wheel rotates in one direction driven by the flip rope, the convex teeth thereon will contact the paddle. The driving force of the convex teeth causes the paddle to start rotating, thereby driving the flip transmission seat (if not restricted by the anti-rotation structure) or only the paddle itself to rotate (if restricted by the anti-rotation structure). After the convex teeth are separated from the paddle, the paddle begins to reset under the action of the elastic reset member. As the flip wheel rotates continuously, the paddle will continuously contact the convex teeth, rotate, separate and reset. This process realizes the continuous transmission and reset of the flip transmission seat (before being restricted by the anti-rotation structure) or the paddle itself (after being restricted by the anti-rotation structure). In this way, this embodiment, through the cooperation of the toggle assembly and the elastic return member, enables the flip transmission seat to automatically rebound during the rotation process, thereby ensuring good contact between the flip wheel and the paddle, ensuring effective transmission between the flip transmission seat and the flip wheel, and realizing smooth flipping operation; in addition, since the contact area between the convex teeth of the flip wheel and the paddle is small, the friction force generated is also relatively small. When the flip transmission seat is limited by the anti-rotation structure, the flip wheel can still continue to rotate, and only needs to overcome the smaller friction force that drives the paddle to rotate, thereby realizing smooth lifting and lowering operations.

[0037] 3. The present invention uses the design of the U-shaped elastic member to effectively reset the paddle when rotating in both directions. This improves the stability and reliability of the flip mechanism. The contact area between the paddle and the U-shaped elastic arm is relatively small, so the friction generated is also small, which helps to further reduce wear and extend the service life of the flip mechanism. Since the paddle can be quickly reset and ready to contact the next convex tooth, the transmission efficiency of the flip mechanism is improved, which makes the raising and lowering operation of the blinds smoother and more efficient.

[0038] 4. The present invention realizes stable rotation control of the flip transmission seat by using the triangular structure and long hypotenuse design of the paddle to enable the paddle to effectively contact with the convex teeth on the flip wheel and transmit power.

[0039] 5. The present invention reduces the friction between the flip transmission seat and the inner wall of the second mounting cavity during the rotation process through the design of the bearing. This not only improves the rotation efficiency, but also prolongs the service life of the flip transmission seat and the bearing. The bearing provides a stable support and rotation axis for the flip transmission seat. This ensures the stability and reliability of the blinds during the flipping process and avoids failures caused by poor rotation or jamming. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Example:

[0057] Please refer to Figure 1-11 As shown, this embodiment provides a single-side controlled hollow glass built-in blinds, including a frame 200 with a blind cavity 210 in the middle, a blind 300 arranged in the blind cavity 210 of the frame 200, two rope ladder fixing devices 400 arranged in the frame 200, and a transmission mechanism respectively connected to the two rope ladder fixing devices 400, and the blinds are respectively connected to the two rope ladder fixing devices;

[0058] The transmission mechanism includes a corner structure 100 and a flip axis 500 installed in the frame 200;

[0059] The corner structure 100 includes a corner mounting seat 10, a traction mechanism 20 and a flipping mechanism 30;

[0060] The corner mounting seat 10 includes an upper mounting seat 101 and a lower mounting seat 102, and the upper mounting seat 101 and the lower mounting seat 102 are connected in a detachable manner; a first mounting cavity 11 is formed on the lower mounting seat 102, and a second mounting cavity 12 is enclosed between the upper mounting seat 101 and the lower mounting seat 102; specifically, the upper mounting seat 101 and the lower mounting seat 102 are connected in a snap-fit ​​manner.

[0061] The traction mechanism 20 includes a traction rope reversing wheel 21, which is rotatably installed in the first installation cavity 11;

[0062] The flip mechanism 30 is rotatably installed in the second installation cavity 12;

[0063] One end of the turning shaft 500 is drivingly connected to the turning mechanism 30 , and the other end thereof is drivingly connected to the two rope ladder fixing devices 400 .

[0064] On the basis of the above structure, the transmission mechanism of the present invention, through the design of the corner structure 100 and the flip shaft 500, raises and lowers the venetian blinds through the traction mechanism, and flips the blades of the venetian blinds through the flip mechanism. The user only needs to operate on one side to achieve the raising and lowering of the venetian blinds and the adjustment of the blade angle, which greatly facilitates the use and improves the user experience. The upper mounting seat and the lower mounting seat are detachably connected, so that the user can easily disassemble the two for maintenance, replacement or cleaning when necessary. At the same time, the second mounting cavity provides a closed installation environment for the flip mechanism, which can effectively prevent the flip mechanism from falling out due to external force or vibration during operation, thereby ensuring the stable operation of the blinds.

[0065] The transmission mechanism also includes a traction rope 800, a flip rope 700, and an inner controller 600; the two ends of the flip rope 700 are respectively connected to the two ends of the inner controller to form a closed loop; the flip rope is also connected to the flip mechanism, and the flip rope is used to drive the flip mechanism to rotate, so as to drive the blades of the blinds to flip; one end of the traction rope 800 is connected to the inner controller, and the other end is connected to the blinds through the traction rope reversing wheel and the rope ladder fixing device in sequence, and the traction rope 800 is used to drive the blinds to rise and fall. It also includes an outer controller, which is connected to the inner controller 600 in a magnetic way.

[0066] In this embodiment, the rope ladder fixing device, the venetian blind, the external operator and the internal operator can all adopt conventional structures, and can refer to the application number CN202011182858.6, and the name is a corner connection structure and venetian blinds.

[0067] Preferably, the flip mechanism 30 includes a flip wheel 31, a flip transmission member 32, a toggle assembly 33, an elastic reset member 34 and a rotation-stopping structure 35;

[0068] The flip transmission member 32 includes a flip transmission seat 321 rotatably mounted in the second mounting cavity 12, a flip shaft connecting tube 322 is disposed at one end of the flip transmission seat 321, and a flip synchronization shaft 323 is disposed at the other end thereof; a mounting hole 3211 is disposed on the flip transmission seat 321;

[0069] The flip wheel 31 is mounted on the flip synchronization shaft 323. A plurality of convex teeth 311 evenly distributed along the circumference of the flip wheel 31 are arranged on the side surface of the flip wheel 31. An accommodating space 312 is formed between any two adjacent convex teeth 311.

[0070] The paddle assembly 33 includes a paddle 331 and a hinge shaft 332. The paddle 331 is rotatably mounted in the mounting hole 3211 via the hinge shaft 332. A portion of the paddle 331 extends into the accommodation space 312 between two adjacent protruding teeth 311.

[0071] The elastic reset member 34 is mounted on the flip transmission seat 321, and the elastic reset member 34 is used to reset the paddle 331 so that a portion of the paddle 331 always extends into the accommodation space 312 between two adjacent protruding teeth 311;

[0072] The anti-rotation structure 35 is located in the second installation cavity 12 , and is used to limit the rotation range of the flip transmission seat 321 .

[0073] According to the corner structure of the venetian blind of the present invention, in the actual working process, in the initial state, the paddle 331 partially extends into the accommodation space 312 between two adjacent convex teeth 311 on the flip wheel 31 under the action of the elastic reset member 34. When the flip wheel 31 rotates in one direction driven by the flip rope, the convex teeth 311 thereon will contact the paddle 331. The driving force of the convex teeth 311 causes the paddle 331 to start rotating, thereby driving the flip transmission seat 321 (if not restricted by the anti-rotation structure 35) or only the paddle 331 itself to rotate (if restricted by the anti-rotation structure 35). After the convex teeth 311 separate from the paddle 331, the paddle 331 starts to reset under the action of the elastic reset member 34. As the flip wheel 31 rotates continuously, the paddle 331 will continuously contact the convex teeth 311, rotate, separate and reset. This process realizes the continuous transmission and reset of the flip transmission seat 321 (before being restricted by the anti-rotation structure 35) or the paddle 331 itself (after being restricted by the anti-rotation structure 35). In this way, the present embodiment, through the cooperation of the toggle assembly 33 and the elastic reset member 34, enables the flip transmission seat 321 to automatically rebound during the rotation process, thereby ensuring good contact between the flip wheel 31 and the paddle 331, ensuring effective transmission between the flip transmission seat 321 and the flip wheel 31, and realizing smooth flipping operation; in addition, since the contact area between the convex teeth 311 of the flip wheel 31 and the paddle 331 is small, the friction force generated is also relatively small. When the flip transmission seat 321 is limited by the anti-rotation structure 35, the flip wheel 31 can still continue to rotate, and only needs to overcome the small friction force that drives the paddle 331 to rotate, thereby realizing smooth lifting and lowering operation.

[0074] In a preferred embodiment of the present invention, a mounting groove 3212 is provided on the side of the flip transmission seat 321 located on one side of the flip synchronization shaft 323;

[0075] The elastic reset member 34 is a U-shaped elastic member, which is installed in the installation groove 3212; the U-shaped elastic member includes a first elastic arm 341 and a second elastic arm 342, and the paddle 331 is located between the first elastic arm 341 and the second elastic arm 342; when the paddle 331 rotates to contact with the first elastic arm 341, it is reset by the first elastic arm 341, and when the paddle 331 rotates in the opposite direction to contact with the second elastic arm 342, it is reset by the second elastic arm 342.

[0076] On the basis of the above structure, in the initial state, the paddle 331 is located between the first elastic arm 341 and the second elastic arm 342 of the U-shaped elastic member, and is in a relatively balanced position. The elastic force of the U-shaped elastic member keeps the paddle 331 in this position, ready to contact the convex teeth 311 of the flip wheel 31. When the flip wheel 31 rotates driven by the flip rope, the convex teeth 311 thereon will contact the paddle 331. The driving force of the convex teeth 311 causes the paddle 331 to start rotating, thereby driving the flip transmission seat 321 (if not restricted by the anti-rotation structure 35) or only the paddle 331 itself to rotate (if restricted by the anti-rotation structure 35). After the convex teeth 311 separate from the paddle 331, the paddle 331 starts to reset under the action of the U-shaped elastic member. If the paddle 331 rotates in one direction before, it will contact the first elastic arm 341 and rebound to the initial position under the elastic force of the first elastic arm 341. If the paddle 331 rotates in the opposite direction, it will contact the second elastic arm 342 and rebound to the initial position under the elastic force of the second elastic arm 342. As the flip wheel 31 rotates continuously, the paddle 331 will continuously contact, rotate, separate and reset with the convex tooth 311. This process realizes the continuous transmission and reset of the flip transmission seat 321 (before being restricted by the anti-rotation structure 35) or the paddle 331 itself (after being restricted by the anti-rotation structure 35). In this way, the present embodiment can effectively reset the paddle 331 when rotating in both directions through the design of the U-shaped elastic member. This improves the stability and reliability of the flip mechanism 30. The contact area between the paddle 331 and the U-shaped elastic arm is relatively small, so the friction force generated is also small, which helps to further reduce wear and extend the service life of the flip mechanism 30. Since the paddle 331 can be quickly reset and ready to contact the next convex tooth 311, the transmission efficiency of the flip mechanism 30 is improved, which makes the lifting and lowering operation of the blinds smoother and more efficient.

[0077] In a preferred embodiment of the present invention, the mounting hole 3211 is a square through hole that penetrates the flip transmission seat 321 along the circumferential direction, and the paddle 331 is in the shape of a triangular structure, which includes two long hypotenuses and one short hypotenuse, and the corner portion between the two long hypotenuses extends into the accommodating space 312 between the two adjacent protruding teeth 311.

[0078] On the basis of the above structure, in the initial state, the corner portion between the two long hypotenuses of the paddle 331 extends into the accommodation space 312 between the two adjacent convex teeth 311. This design ensures that the paddle 331 maintains effective contact with the convex teeth 311 in the initial position. When the flip wheel 31 rotates driven by the flip rope, the convex teeth 311 thereon will contact the long hypotenuse of the paddle 331. The driving force of the convex teeth 311 causes the paddle 331 to start rotating, thereby driving the flip transmission seat 321 (if it is not restricted by the anti-rotation structure 35) or only the paddle 331 itself to rotate (if it is restricted by the anti-rotation structure 35). In this way, the triangular structure and long hypotenuse design of the paddle 331 in this embodiment enable the paddle 331 to effectively contact and transmit power with the convex teeth 311 on the flip wheel 31, thereby realizing stable rotation control of the flip transmission seat 321.

[0079] In a preferred embodiment of the present invention, a bearing 36 is further included which is installed on the flip shaft connecting tube 322 . The inner ring of the bearing 36 is tightly matched with the flip shaft connecting tube 322 , and the outer ring thereof is in contact with the inner wall of the second installation cavity 12 .

[0080] On the basis of the above structure, the design of the bearing 36 enables the flip transmission seat 321 to reduce the friction with the inner wall of the second installation cavity 12 during the rotation process. This not only improves the rotation efficiency, but also prolongs the service life of the flip transmission seat 321 and the bearing 36. The bearing 36 provides a stable support and a rotation axis for the flip transmission seat 321. This ensures the stability and reliability of the shutter during the flipping process and avoids failures caused by poor rotation or jamming.

[0081] In a preferred embodiment of the present invention, the number of convex teeth 311 is four to eight. On the basis of the above structure, the increase in the number of convex teeth 311 can improve the transmission efficiency, because more convex teeth 311 means that during the process of one rotation of the flip wheel 31, the paddle 331 contacts the convex teeth 311 more times, and the transmission is more continuous and smooth. However, too many convex teeth 311 will also increase the complexity of the structure and the manufacturing cost, and may cause interference and noise problems during the transmission process. The number of convex teeth 311 is usually selected between four and eight. This range not only ensures the transmission efficiency, but also avoids the complexity of the structure, excessive noise and increased cost caused by too many convex teeth 311.

[0082] More preferably, the number of the protruding teeth 311 is six. In the range of four to eight, six protruding teeth 311 are generally considered to be a more preferred number because it can achieve a good balance between transmission efficiency, control accuracy, structural simplicity and noise control.

[0083] In a preferred embodiment of the present invention, the stop structure 35 includes a stop protrusion 351 arranged on the flip transmission seat 321, and a first stop portion 352 and a second stop portion 353, the first stop portion 352 and the second stop portion 353 are respectively symmetrically arranged in the second mounting cavity 12 along the vertical direction, and the first stop portion 352 and the second stop portion 353 are respectively arranged at the front and rear sides of the flip transmission seat 321; the flip transmission seat 321 drives the stop protrusion 351 to rotate, and when the stop protrusion 351 rotates to contact with the first stop portion 352, it is limited by the first stop portion 352, and when the stop protrusion 351 rotates to contact with the second stop portion 353, it is limited by the second stop portion 353.

[0084] In actual operation, when the flip wheel 31 rotates in one direction driven by the flip rope, a convex tooth 311 on the flip wheel 31 contacts the paddle 331 and drives the paddle 331 to rotate. The paddle 331 squeezes the elastic reset member 34 during the rotation process, and the paddle 331 drives the flip transmission seat 321 and the anti-rotation protrusion 351 thereon to rotate together. When the anti-rotation protrusion 351 rotates to contact the first stopper 352, the first stopper 352 limits the flip transmission seat 321 to prevent it from continuing to rotate; similarly, when the anti-rotation protrusion 351 rotates to contact the second stopper 353, the second stopper 353 also limits the flip transmission seat 321. In this way, the rotation range of the flip transmission seat 321 is limited between the first stopper 352 and the second stopper 353. In this way, the anti-rotation structure 35 of this embodiment includes a anti-rotation protrusion 351, a first stop portion 352 and a second stop portion 353, which effectively limits the rotation range of the flip transmission seat 321, improves the stability and reliability of the corner structure, is easy to manufacture and install, and reduces production costs and difficulty.

[0085] In a preferred embodiment of the present invention, the corner mounting seat 10 is further provided with a longitudinal connecting channel 121 and a transverse connecting channel 122 respectively connected to the second mounting cavity 12; the longitudinal connecting channel 121 has an inlet 1211 for the turning rope to pass through, and the transverse connecting channel 122 has an insertion port 1221 for the turning shaft to pass through;

[0086] The corner mounting seat 10 is also provided with a longitudinal rope inlet channel 111 and a transverse rope outlet channel 112 which are respectively connected to the first mounting cavity 11; the longitudinal rope inlet channel 111 has a rope inlet opening 1111 for the traction rope to pass through, and the transverse rope outlet channel 112 has a rope outlet opening 1121 for the traction rope to pass through.

[0087] On the basis of the above structure, the flip rope enters the second installation cavity 12 through the longitudinal connecting channel 121 and is connected to the flip wheel 31, thereby driving the flip wheel 31 to rotate; and the flip shaft is connected to the flip shaft connecting tube 322 through the transverse connecting channel 122 to achieve stable transmission of power. The traction rope enters the first installation cavity 11 through the longitudinal rope inlet channel 111 and is connected to the traction rope reversing wheel 21 to achieve transmission and reversal of traction force. The traction rope leaves the first installation cavity 11 through the transverse rope outlet channel 112 and continues to transmit power to other parts of the blinds. In this way, the flip rope and traction rope of this embodiment can be accurately guided and transmitted in the corner mounting seat 10, avoiding the entanglement and knotting of the rope, and ensuring the smoothness and accuracy of the lifting or flipping action of the blinds blades.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
