Description

Technical Field

[0001] The invention relates to the technical field of blinds, in particular to a hollow blind. Background Art

[0002] Venetian blinds, also known as sunshades or leaf windows, are a common type of window used to adjust indoor light and protect privacy. Venetian blinds consist of multiple horizontally arranged blades (or louvers), which can be fixed to the window frame or movable, allowing users to adjust by rotating or pulling. By adjusting the angle of the louver blades, the amount of light entering the room can be controlled, thereby achieving indoor light regulation, and there are gaps between the blades of the louver to maintain indoor air circulation.

[0003] Unlike conventional blinds, blinds installed in hollow glass are in a closed environment. In order to improve the sound insulation and heat insulation effect of double-layer glass and reduce the resistance encountered when adjusting the blinds, the inside of the glass is usually vacuumed when double-layer glass is installed, which means that hollow blinds are in a negative pressure environment for a long time.

[0004] However, during the use of glass windows, people's activities and collisions with glass windows when carrying objects may cause the glass to shatter. Since glass repair takes a certain amount of time, especially when the outer glass is damaged and waiting for repair, the blinds are exposed and constantly swing back and forth under the action of wind, making noise, affecting the work of people in the office. In addition, when the blades of conventional blinds fit together for shading, there are gaps between adjacent blades, resulting in limited shading effect of the blinds.

[0005] Therefore, a hollow shutter is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a hollow Venetian blind, which can sense the change in environmental pressure after the glass is broken and start accordingly, so that the blades have no gaps and are tightly fitted. This solves the problem that the Venetian blind swings back and forth under the action of wind after the glass is broken, causing noise and the limited shading effect in daily use. The Venetian blind has the effect of forming a windshield structure after the glass is broken, avoiding swinging back and forth and improving the shading degree in daily use.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] There are differences between the blinds used in daily life and the hollow blinds used in hollow glass. Under normal circumstances, in order to improve the sound insulation and heat insulation effect of the hollow glass, the inside of the hollow glass is usually vacuumed. The vacuuming operation can also reduce the resistance encountered when the hollow blinds are turned over. In order to ensure the ventilation effect of conventional blinds, adjacent blades cannot be completely fitted together when shading. When conventional blinds are used in hollow glass, the shading effect will be affected by the unnecessary ventilation effect. For this reason, this technical solution optimizes the shading effect of vacuum blinds without ensuring the ventilation effect.

[0009] A hollow shutter comprises a top frame, a vertical plate, and also comprises a shading adjustment component, a glass detection component, a winding and releasing component, a connecting wire, a blade, a first arc-shaped piece, a second arc-shaped piece, a thin rope, and a bottom plate. The shading adjustment component and the winding and releasing component are both installed between the side walls of the vertical plate, and the shading adjustment component is located above the winding and releasing component, the glass detection component is suspended on the inner side of the top frame, the connecting wires are distributed in a rectangular shape and fit at both ends of the shading adjustment component, the blades are arranged at equal intervals, the first arc-shaped piece and the second arc-shaped piece are respectively fitted on both sides of the blade, and the first arc-shaped piece and the second arc-shaped piece are installed between the connecting wires, the top of the thin rope is connected to the winding and releasing component, and the bottom of the thin rope passes through under the blade, and the bottom plate is installed at the bottom of the thin rope. When the glass is broken, the glass detection component connects the shading adjustment component and the winding and releasing component to the power supply through the glass detection component, and the winding and releasing component releases the thin rope. After the thin rope is completely released, the shading adjustment component drives the blade to rotate and the first arc-shaped piece and the second arc-shaped piece are staggered and fitted.

[0010] As mentioned above, when the glass is not broken, the glass detection component is in a negative pressure environment and is compressed. When the glass is broken, the glass detection component is in the atmospheric environment and recovers to its original volume due to the elasticity of the material, thereby identifying the glass breakage, and then turning on the power of the shading adjustment component and the winding and releasing component. According to the set procedure, the blades are first completely released through the winding and releasing component, and then the shading adjustment component is used to flip the blades, so that the first arc-shaped piece and the second arc-shaped piece are misaligned and tightly fitted, and the blinds are in a closed state, thereby forming a closed shielding; in addition, the connecting wire can not only act as a "trapezoidal belt" connecting the blades, but also can transmit electricity when the window is broken.

[0011] Preferably, the shading adjustment assembly includes a motor frame, a reciprocating motor, a worm, a worm wheel, an adjustment shaft and an adjustment block. The motor frame is fittedly mounted on the inner wall of the top frame, the reciprocating motor is mounted on the inner side of the motor frame, the worm wheel is mounted on the output shaft of the reciprocating motor, the adjustment blocks are rotatably connected to the vertical plates respectively, the adjustment shaft is installed between the ends of the adjustment blocks, the worm wheel is sleeved in the middle position of the adjustment shaft, and the worm wheel is meshed with the worm wheel.

[0012] As mentioned above, the output shaft of the reciprocating motor controls the rotation of the adjustment shaft and the adjustment block through the cooperation of the worm gear and the worm. When the adjustment block rotates to either side, the connecting wire on the other side will move toward the rotating side, thereby lifting the connecting wire on that side and quickly changing the light transmission area of ​​the blinds.

[0013] Preferably, the first arc-shaped piece and the second arc-shaped piece have the same curvature radius, the first arc-shaped piece and the second arc-shaped piece are both provided with a straight groove on their edges, and the first electromagnet bar and the second electromagnet bar are respectively installed in the straight grooves of the first arc-shaped piece and the second arc-shaped piece, the first electromagnet bar and the second electromagnet bar are both electrically connected to the connecting wire, and an extension strip is fitted on the inner circumference of the second arc-shaped piece.

[0014] As mentioned above, after the glass detection component expands, the power of the first electromagnet bar and the second electromagnet bar is turned on through the glass detection component and the connecting wire. When the first arc-shaped piece and the second arc-shaped piece are deflected and fitted together, the magnetic adsorption effect of the first electromagnet bar and the second electromagnet bar can be used to effectively enhance the fitting effect of adjacent blades, effectively avoiding gaps between the blades caused by wind and noise when swinging.

[0015] Preferably, arc-shaped grooves are formed on the outer circumferences of the first arc-shaped piece and the second arc-shaped piece.

[0016] As mentioned above, by utilizing the design of the arc groove, when the blades are deflected, the connecting wires between the adjacent first arc pieces and the second arc pieces follow the arc groove to fit with the arc portions of the first arc pieces and the second arc pieces, causing the lower blades to move slightly upward as a whole when shading is performed, to ensure that the edge of the first arc piece and the edge of the second arc piece fit together. Compared with traditional blinds, gaps between adjacent blades can be avoided, thereby greatly improving the shading effect of the hollow blinds.

[0017] Preferably, a rope groove for the thin rope to pass through is opened on the surface of the blade, and a symmetrically arranged light-blocking curtain is fitted in the rope groove.

[0018] As described above, when the thin rope swings along the rope groove, the light-blocking curtain can be continuously reset, thereby preventing a large area of ​​the rope groove from being exposed, thereby further improving the light-blocking effect of the hollow blinds.

[0019] Preferably, the glass detection assembly includes an airbag bag, a sealing block, a first conduction rod, and a second conduction rod. The sealing block is installed on both sides of the airbag bag, and the first conduction rod and the second conduction rod are respectively installed on the inner walls of the sealing block, and the first conduction rod and the second conduction rod are distributed in an X shape. When the glass breaks, the airbag bag expands to drive the first conduction rod and the second conduction rod to fit together.

[0020] As mentioned above, when the glass is broken, the air pressure of the environment in which the airbag bag is located changes, and the corresponding state is quickly executed by utilizing the air pressure change, without the need to use intelligent sensors to monitor the damage of the glass, thereby reducing the manufacturing cost of the present technical solution.

[0021] Preferably, the glass detection assembly further comprises a limiting rod and a limiting cylinder, the limiting cylinder is attached to the inner wall of the airbag bag, and the limiting rod is slidably installed inside the limiting cylinder.

[0022] As described above, the cooperation of the limiting rod and the limiting cylinder can ensure that the shape of the airbag bag remains relatively unchanged in a negative pressure environment, and prevent the first conduction rod and the second conduction rod from sticking to each other and connecting the power of the shading adjustment component and the winding and releasing component.

[0023] Preferably, the winding and releasing assembly includes a servo motor, a connecting shaft and a winding drum, the servo motor is installed on the side wall of the vertical plate, the connecting shaft is connected to the servo motor output shaft, the winding drum is installed at the end of the connecting shaft, and the outer periphery of the winding drum is fixedly fitted with the end of the thin rope.

[0024] As described above, a servo motor is used to control the winding and releasing of the thin rope. After the servo motor is powered off, the self-locking function of the servo motor is utilized to prevent the thin rope from being freely released.

[0025] Preferably, a docking groove adapted to the first arc-shaped piece is provided between the edge of the second arc-shaped piece and the extension strip.

[0026] As mentioned above, after the blade drives the first arc-shaped piece and the second arc-shaped piece to flip, the edge of the first arc-shaped piece can be inserted into the docking groove, thereby avoiding the existence of a light-transmitting gap between the first arc-shaped piece and the second arc-shaped piece, thereby further improving the shading effect of the hollow blinds.

[0027] Preferably, a photosensitive sensor is installed on the outer wall of the top frame, and an intelligent controller is installed on the inner wall of the top frame, and the intelligent controller is electrically connected to the photosensitive sensor, the shading adjustment component and the winding and releasing component respectively.

[0028] As described above, under the action of the photosensitive sensor and the intelligent controller, the intelligent mode can be set during daily use. When the outdoor light intensity is high, the monitoring of the photosensitive sensor can be used to achieve intelligent control, thereby improving the intelligent effect of the hollow blinds.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Through the glass detection component set up, for the environmental scene of hollow Venetian blinds, the volume of the airbag bag is changed by the change of air pressure when the glass is broken, and the power of the shading adjustment component and the winding and releasing component is turned on accordingly. After the blades are rotated, the first arc piece and the second arc piece are fitted together. Combined with the adsorption effect of the electromagnet bar, the Venetian blinds can be prevented from shaking and making noise due to the action of wind during glass repair.

[0031] 2. By setting the blades, the first arc-shaped piece, the second arc-shaped piece, the extension bar, the connecting wire, the first electromagnet bar and the second electromagnet bar, when the blades are flipped for shading and complete shading is required, the edge of the first arc-shaped piece can be fitted with the edge of the second arc-shaped piece and the extension bar, thereby avoiding the existence of light-transmitting gaps between adjacent blades when complete shading is performed, thereby further improving the shading effect. In addition, through the adsorption effect of the electromagnet bar, the stability between adjacent blades can be effectively enhanced, effectively preventing the blinds from shaking due to wind.

[0032] 3. By setting the first arc-shaped piece, the second arc-shaped piece and the connecting wire, when the blade is flipped, the local position of the connecting wire will be affected by the arc-shaped parts of the first arc-shaped piece and the second arc-shaped piece, causing the first arc-shaped piece and the second arc-shaped piece to move slightly upward, ensuring the fit of the first arc-shaped piece and the second arc-shaped piece. In addition, when there is no need for shading and the blades need to be hung down, the distance between adjacent blades can be effectively increased, thereby ensuring the lighting effect.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 8 The present invention provides a hollow shutter, and the technical solution is as follows:

[0044] Reference Figures 1 to 3A hollow Venetian blind comprises a top frame 1 and a vertical plate 3. The vertical plates 3 are two in number. A through slot is provided on the top of the top frame 1 for easy maintenance. The vertical plates 3 are symmetrically mounted on the inner top surface of the top frame 1 about the through slot. The hollow Venetian blind comprises a shading adjustment component 2, a glass detection component 4, a winding and releasing component 5, a connecting wire 6, a blade 7, a first arc-shaped piece 8, a second arc-shaped piece 9, a thin rope 10, and a bottom plate 11. The shading adjustment component 2 and the winding and releasing component 5 are both mounted between the side walls of the vertical plate 3, and the shading adjustment component 2 is located above the winding and releasing component 5. The working principles of the shading adjustment component 2 and the winding and releasing component 5 are the same as those of traditional Venetian blinds. The glass detection component 4 is suspended. Hanging on the inner side of the top frame 1, when any one or two of the two side glasses of the hollow blinds are broken at the same time, the air pressure of the environment in which the glass detection component 4 is located changes. When the glass detection component 4 transitions from the negative pressure environment to the atmospheric environment, the volume of the glass detection component 4 will increase accordingly, thereby performing the corresponding operation; the connecting wires 6 are distributed in a rectangular shape and fit at both ends of the shading adjustment component 2. The number of the connecting wires 6 is four. The connecting wires 6 are connected to the glass detection component 4. After the glass detection component 4 is started, a current loop is formed between the connecting wires 6. When the glass detection component 4 is not started, the connecting wires 6 are in a non-charged state. In addition, since the connecting wires 6 are " The role of the "trapezoidal belt" requires that the connecting wire 6 has a certain connection strength. Therefore, the connecting wire 6 is a single-strand TRVV cable with good bending and stretch resistance. The blades 7 are arranged at equal intervals. The first arc piece 8 and the second arc piece 9 are respectively installed on both sides of the blade 7, and the first arc piece 8 and the second arc piece 9 are installed between the connecting wire 6. The contact part between the connecting wire 6 and the first arc piece 8 and the second arc piece 9 is fixedly connected. The top of the thin rope 10 is connected to the winding and releasing component 5, and the bottom of the thin rope 10 passes through the bottom of the blade 7. The bottom plate 11 is installed at the bottom of the thin rope 10. When the winding and releasing component 5 rolls up the thin rope 10, the bottom plate will be lifted first. 11. As the bottom plate 11 continues to move upward, the multiple blades 7 will be driven to move upward slowly until the multiple blades 7 are stored inside the top frame 1. When the glass is broken, the glass detection component 4 connects the power of the shading adjustment component 2 and the winding and releasing component 5 through the glass detection component 4, and the winding and releasing component 5 releases the thin rope 10. After the thin rope 10 is completely released, the shading adjustment component 2 drives the blades 7 to rotate and the first arc-shaped piece 8 and the second arc-shaped piece 9 are staggered and fitted. A photosensor 12 is installed on the outer wall of the top frame 1, and an intelligent controller 13 is installed on the inner wall of the top frame 1. The intelligent controller 13 is electrically connected to the photosensor 12, the shading adjustment component 2 and the winding and releasing component 5 respectively.

[0045] Reference Figure 4As an implementation scheme of the present technical scheme, specifically, the shading adjustment component 2 includes a motor frame 21, a reciprocating motor 22, a worm 23, a worm gear 24, an adjustment shaft 25 and an adjustment block 26. The motor frame 21 is fitted on the inner wall of the top frame 1, the reciprocating motor 22 is installed on the inner side of the motor frame 21, the worm 23 is installed on the output shaft of the reciprocating motor 22, the adjustment blocks 26 are respectively connected to the vertical plates 3 for rotation, the adjustment shaft 25 is installed between the ends of the adjustment blocks 26, the worm gear 24 is sleeved in the middle position of the adjustment shaft 25, and the worm gear 24 is meshed with the worm 23; when the reciprocating motor 22 drives the worm 23 to rotate, the adjustment shaft 25 and the adjustment block 26 at the end of the adjustment shaft 25 are driven to rotate through the cooperation of the worm 23 and the worm gear 24, thereby causing the connecting wires 6 on both sides of the adjustment block 26 to move up and down respectively, so that the height difference between the first arc-shaped piece 8 and the second arc-shaped piece 9 is further changed, thereby changing the horizontal angle of the blade 7, thereby achieving different degrees of shading requirements of the blinds.

[0046] Reference Figure 5 As an implementation scheme of the present technical scheme, specifically, the first arc-shaped piece 8 and the second arc-shaped piece 9 have the same curvature radius, and the first arc-shaped piece 8 and the second arc-shaped piece 9 have the same shape and size. The first arc-shaped piece 8 and the second arc-shaped piece 9 have a straight groove 81 at their edges, and the first electromagnet bar 82 and the second electromagnet bar 84 are respectively fitted and installed in the straight groove 81 of the first arc-shaped piece 8 and the second arc-shaped piece 9. The power-connecting ends of the first electromagnet bar 82 and the second electromagnet bar 84 are connected to the connecting wire 6 at the same end of the corresponding side of the blade 7, and the connecting wire 6 at this end is the live wire, and the connecting wire 6 at the other end is the neutral wire. The first electromagnet bar 82 and the second electromagnet bar 84 are both electrically connected to the connecting wire 6. Considering the maintenance of the glass The maintenance time is usually about several hours. When it is close to the end of get off work, you need to wait until the next day to go to work before replacing the glass. At this time, the maintenance time is relatively long. Although people do not need to go to work at night, after the glass is broken, a pressure difference will be formed inside and outside the window due to the strong wind. Under the action of the pressure difference, it is easy to cause the paper documents in the office to be sucked out of the window. Therefore, it is necessary to control the first electromagnet bar 82 and the second electromagnet bar 84 to be continuously energized. For this reason, the first electromagnet bar 82 and the second electromagnet bar 84 are selected from electromagnet bars that can be energized for a long time. The long-term energization design is used to ensure that the heat rise of the coil and the iron core is within a safe range during continuous work. The inner circumference of the second arc-shaped piece 9 is attached with an extension strip 91; when the edges of the first arc-shaped piece 8 and the second arc-shaped piece 9 are attached to each other, refer to the attached Figure 6As shown, the connecting wire 6 that replaces the "trapezoidal belt" in the traditional blinds can transmit electricity. Under the action of the intelligent controller 13 equipped in the present application, the power supply of the first electromagnet bar 82 and the second electromagnet bar 84 is connected through the matching circuit board, and the first electromagnet bar 82 and the second electromagnet bar 84 are attracted to each other by the difference in magnetism of the adjacent sides, thereby improving the stability between the blades 7, and the blinds have a strong wind resistance and anti-swing effect; the outer periphery of the first arc piece 8 and the second arc piece 9 are provided with an arc groove 83, and the arc groove 83 can accommodate a certain length of the connecting wire 6, thereby avoiding that the relative spacing of the blades 7 after flipping is greatly affected by the thickness of the first arc piece 8 and the second arc piece 9; a docking groove adapted to the first arc piece 8 is provided between the edge of the second arc piece 9 and the extension strip 91; the first arc piece 8 and the second arc piece 9 are flipped at the same time, and when the first arc piece 8 and the second arc piece 9 are flipped and docked, the edge of the first arc piece 8 can be inserted into the docking groove between the second arc piece 9 and the extension strip 91.

[0047] Reference Figure 5 As an implementation scheme of the present technical solution, specifically, a rope groove 71 is provided on the surface of the blade 7 for the thin rope 10 to pass through, and a symmetrically arranged light-blocking curtain 72 is fitted in the rope groove 71. When the blade 7 is deflected, the thin rope 10 swings in the rope groove 71. During the swing, the light-blocking curtain 72 that is not pushed open by the thin rope 10 returns to its original position to cover the rope groove 71, thereby greatly improving the light-blocking effect of the blade 7.

[0048] Reference Figure 7As an implementation of the present technical solution, specifically, the glass detection assembly 4 includes an airbag bag 41, a sealing block 42, a first conductive rod 43, and a second conductive rod 44. The sealing block 42 is installed on both sides of the airbag bag 41, and the first conductive rod 43 and the second conductive rod 44 are respectively installed on the inner wall of the sealing block 42, and the first conductive rod 43 and the second conductive rod 44 are distributed in an X shape. When the glass is broken, the airbag bag 41 expands and drives the first conductive rod 43 and the second conductive rod 44 to fit together. A U-shaped groove is opened in the middle part of the first conductive rod 43, and the second conductive rod 44 passes through the U-shaped groove and does not contact the first conductive rod 43. Therefore, when the airbag bag 41 is in a negative pressure environment, the wire formed by the first conductive rod 43 and the second conductive rod 44 is in a broken state. state, and when the airbag bag 41 is converted from a negative pressure environment to an atmospheric environment, the airbag bag 41 expands, and the first conduction rod 43 and the second conduction rod 44 move away from each other so that the first conduction rod 43 and the second conduction rod 44 are in contact, thereby connecting the standby circuits of the shading adjustment component 2 and the winding and releasing component 5, so that the shading adjustment component 2 and the winding and releasing component 5 perform operations pre-set according to the program under the action of the intelligent controller 13; the glass detection component 4 also includes a limit rod 45 and a limit cylinder 46, the limit cylinder 46 is attached to the inner wall of the airbag bag 41, and the limit rod 45 is slidably installed between the inside of the limit cylinder 46, and the limit rod 45 and the limit cylinder 46 are limited by the cooperation, so that the shape of the airbag bag 41 in the negative pressure environment remains relatively unchanged.

[0049] Reference Figure 8 As an implementation scheme of the present technical solution, specifically, the winding and releasing assembly 5 includes a servo motor 51, a connecting shaft 52 and a winding drum 53. The servo motor 51 is installed on the side wall of the vertical plate 3, the connecting shaft 52 is connected to the output shaft of the servo motor 51, and the winding drum 53 is installed at the end of the connecting shaft 52. The outer periphery of the winding drum 53 is fixedly fitted with the end of the thin rope 10; when the servo motor 51 drives the connecting shaft 52 and the winding drum 53 to rotate in the corresponding direction, the thin rope 10 will be wound around the outer periphery of the winding drum 53 or the thin rope 10 will be released from the outer periphery of the winding drum 53, thereby changing the height of the bottom plate 11 and the drooping range of the blade 7.

[0050] Working principle: When the glass on the outside of the hollow blinds is broken, the volume change caused by the change in the pressure of the environment in which the airbag bag 41 is located quickly performs the wind-proof and noise-reducing operation. First, the winding and releasing component 5 releases the thin rope 10 to hang down all the blades 7, and then the shading adjustment component 2 drives the blades 7 to deflect to the corresponding side, so that the edges of the first arc-shaped piece 8 and the second arc-shaped piece 9 fit together, and finally the power supply of the first electromagnet bar 82 and the second electromagnet bar 84 is turned on to improve the fitting effect of the first arc-shaped piece 8 and the second arc-shaped piece 9;

[0051] Specifically, when the glass is shattered by external factors, the airbag bag 41 is converted from a negative pressure environment to an atmospheric environment and expands, and the first conduction rod 43 and the second conduction rod 44 move away from each other. When the first conduction rod 43 and the second conduction rod 44 contact, the standby circuits of the shading adjustment component 2 and the winding and releasing component 5 are connected, so that the shading adjustment component 2 and the winding and releasing component 5 perform operations pre-set according to the program under the action of the intelligent controller 13. First, the servo motor 51 rotates to release the thin rope 10, so that all the blades 7 droop, and the connecting wire 6 is in a vertical state at this time; then the reciprocating motor 22 drives the worm 23 to rotate, and the worm 23 and the worm wheel 24 cooperate to drive the adjusting shaft 25 and the adjusting block 26 to rotate at the same time, so that the connecting wire 6 on the side of the first arc-shaped piece 8 moves up and the second arc-shaped piece 8 moves down. The connecting wire 6 on the side of 9 moves downward, the height difference between the first arc piece 8 and the second arc piece 9 changes further, and the horizontal angle of the blade 7 changes accordingly, until the edge of the first arc piece 8 fits with the edge of the second arc piece 9. During the rotation of the blade 7, the connecting wire 6, under the action of the arc portion of the first arc piece 8 and the second arc piece 9, reduces the height difference between the first arc piece 8 and the second arc piece 9, so that the first arc piece 8 and the second arc piece 9 are misaligned and fit together. Finally, the intelligent controller 13 turns on the front-end circuit of the connecting wire 6, thereby turning on the power supply of the first electromagnet bar 82 and the second electromagnet bar 84. The adjacent sides of the first electromagnet bar 82 and the second electromagnet bar 84 have opposite magnetic properties, thereby forming a tight adsorption, ensuring the connection stability between adjacent blades 7, and preventing the blades 7 from generating gaps and emitting noise when the wind blows.
