Description

Remote control type magnetic drive hollow glass built-in shutter

Technical Field

The invention belongs to the technical field of sun-shading hollow glass products, and particularly relates to a remote control type magnetic drive hollow glass built-in shutter.

Background

The hollow glass built-in blind described above mainly refers to, but is not absolutely limited to, a double-layer hollow glass built-in blind (hereinafter the same), for example, there are also a plurality of layers such as three-glass two-chamber hollow glass built-in blind as in chinese patents CN105041268B and CN 10504169B. The hollow glass built-in shutter has the following advantages: the heat insulation performance is good, so that the energy conservation of the building can be embodied; excellent sound insulation performance to avoid the disturbance of external noise; the condensation and frost prevention can ensure sufficient indoor light and show expected bright effect; the required indoor lighting requirement is obtained and the privacy is protected by adjusting the deflection angle, namely the turning angle, of the curtain sheet of the blind; the shutter curtain sheet (the habit is called as the 'curtain sheet' for short) is prevented from being polluted by dust, so that the excellent cleaning-free effect is embodied; the decorative board has ideal decorative property for buildings so as to improve the grade of the buildings; strong impact resistance, good safety and long service life, thereby meeting the installation requirements of high-rise buildings and the extremely long-term use and maintenance-free requirements, and the like.

Technical information on a hollow glass built-in louver is not disclosed in the published Chinese and foreign patent documents, such as CN2564720Y (hollow glass with built-in louver), CN2767624Y (louver in hollow glass), CN2767625Y (louver in hollow glass with improved structure), CN2756796Y (louver in hollow glass), CN2232968Y (integral door and window sash with transverse louver in double glass), CN2297952Y (magnetically driven laminated retractable curtain), CN2326718Y (fully enclosed louver), CN100535378C (louver in hollow glass with improved structure), CN102444372A (a built-in sun-shading hollow louver), CN105064896B (single-control double-layer hollow glass built-in louver), CN105041168B (energy-saving multilayer hollow glass louver with simplified structure), CN105041170B (non-magnet driven double-layer hollow glass built-in louver), CN105041172B (bead chain double-layer hollow glass built-in louver), CN109538096A (double-control hollow glass built-in louver with louver cavity balanced with external pressure), CN109538097A (blind anti-slipping device for hollow glass built-in blind), CN109441323A (single-control hollow glass built-in blind capable of preventing blind slipping down) and CN109488189A (single-control hollow glass built-in blind capable of preventing inner absorption of glass), foreign patents such as US20021897681A, 1US2004211528A, US2015159431a1, GB671685A, EP2369121a2, EP1542054a1 and W003071082A, and the like.

Common features of the hollow glass built-in blind, not limited to the above examples, are: the turnover of the curtain sheet and the lifting of the blind are realized by hand driving operation, namely, the turnover of the curtain sheet and the lifting of the blind are realized by manual operation of a manual operation mechanism. The components of the structural system of the manual operating mechanism comprise an inner manipulator and an outer manipulator, the outer manipulator which is arranged on one side of the inner glass back to the outer glass in a vertically moving mode is magnetically attracted together with the inner manipulator arranged between the inner glass and the outer glass through the inner glass, a turnover shaft driving device corresponding to the upper part of the inner manipulator is connected with a turnover shaft of the structural system of the curtain turnover and shutter lifting actuating mechanism, a curtain turnover traction rope is connected with a rope winding wheel of the structural system of the inner manipulator and the turnover shaft driving device and a curtain turnover traction rope tensioning device corresponding to the lower part of the inner manipulator, so that when a user moves the outer manipulator upwards or downwards, the outer manipulator drives the inner manipulator to correspondingly move upwards and downwards, the inner manipulator drives the curtain turnover traction rope, and the curtain turnover traction rope drives the rope winding wheel of the structural system of the turnover shaft driving device, because the turning shaft is fixedly inserted with the rope winding wheel, the rope winding wheel drives the curtain piece to turn and the shutter lifting actuating mechanism to move, so that the curtain piece can be turned as required or the shutter can be lifted as required.

From the above description, it can be seen that: if the blind slats are turned over a certain angle to meet the lighting requirement in a room and the blind slats are raised or lowered as required, the blind slats must be raised or lowered by a user by dialing up or down the aforementioned external controller, and the operation mode of the structure becomes a mode generally acquiescent and accepted by a large number of users, but the operation mode has at least the following technical problems objectively: first, if the aforementioned inner and outer manipulators are mismatched with each other in terms of attraction force for attracting each other across the inner glass and the mass (weight) of the blind between the inner and outer glasses, for example, the attraction force is too small, abnormal sliding occurs and the blind cannot be reliably maintained at the desired raised position, whereas the operation is laborious and the cost of the inner and outer manipulators is increased blindly, since increasing the number of permanent magnets, which are relatively expensive, and/or increasing the volume of the permanent magnets inevitably increases the cost significantly; secondly, as long as the situation that the outer controller is manually moved is existed, the manual operation is relatively laborious, especially, the larger the breadth width of the blind is, the heavier the whole weight of the blind is, the stronger the magnetic attraction force of the mutual attraction of the inner controller and the outer controller is, which is very embarrassing or called as difficult for the weak such as minors and old people; thirdly, once the inner manipulator has the situation of affecting sliding such as displacement, deformation and clamping stagnation, the repair is quite troublesome, the inner manipulator needs to be repaired by a manufacturer or an original installer or a professional, the repair usually needs to remove the inner glass, the work load is large, the time is long, the payment cost is high, and in consideration of the factors, a user is usually unwilling to maintain and use the inner manipulator, so that the inner manipulator is placed and even burdensome; fourthly, since a sliding channel needs to be provided for the inner manipulator, the lighting area is affected to a certain extent.

The 'electric rotary magnetic transmission built-in sunshade hollow glass' recommended by the Chinese invention patent application publication No. CN110513023A can make up for the above-mentioned deficiencies of the applicant to a certain extent due to the adoption of an external magnetic transmission electric manipulator and a driven magnetic transmission piece in a cavity, but the patent application still has the following disadvantages: firstly, since this patent teaches in paragraph 0029 that the motor is provided with special positioning grooves and ribs to position the motor in the housing (referred to as "housing seat"), the structure of the motor is relatively complicated, which is troublesome for the manufacturer of the motor and the manufacturer of the hollow built-in louver, and the complexity of the structure of the motor increases the cost of the motor; secondly, because no suggestion is given on how to reasonably fix the shell with the motor, the non-metallic separator, the magnetic column and the like which are installed in the shell and the inner glass of the hollow glass built-in shutter under the use state, the magnetic attraction of the magnetic column (namely the outer magnetic column) of the external magnetic-driven electric controller on the magnetic column (namely the inner magnetic column) of the structural system corresponding to the driven magnetic transmission part in the cavity is not perfect enough, for example, once the external magnetic controller is impacted or collided by abnormal external factors to cause deviation or even fall off, the re-matching effect of the external magnetic controller and the inner magnetic column can be influenced, and especially for users, the problem of taking measures is often generated; third, although the patent in paragraph 0028 mentions the content of the power line connecting the power source, it also does not teach how to make the motor work, such as how to supply power to the motor, how to operate the indispensable components of the motor, how to arrange the housing with the motor, etc. In view of the foregoing, there is a need for improvement, and the technical solutions described below are made in this context.

In the same way, specifically, when the corresponding arrow on the wireless remote control signal transmitter 30 is operated, such as a downward arrow or a prompted chinese message, the wireless signal receiving controller 6 receives a signal to make the operation direction of the tubular motor 2 opposite to the operation direction, i.e. in the counterclockwise operation state, so as to realize the lowering of the blind 8 or the outward turning of the blind 84. The indicator lamps 613 can display three states: the green light flashes, representing normal operation; the yellow light flashes to represent that the remote controller and the control circuit board 61 are in code matching; the red light is on, representing an operational failure.

The applicant needs to state that: if the cross-sectional shape of the actuator acting shaft fitting hole 9221 is changed to a pentagon or octagon of equal side lengths or the like and the cross-sectional shape of the actuator acting shaft 10 is adaptively changed, it should be regarded as not to depart from the technical scope of the present disclosure.

The applicant needs to state that: if the pair of screw rods 932 are combined into one, i.e. become one screw rod 932, and the screw rod bearing 931 is omitted, the form should be regarded as a non-essential change and still fall into the technical meaning and scope of the present disclosure, because the technical means, the purpose, the technical effect, etc. are still basically the same; alternatively, when the pair of lead screws 932 is changed to one, the lead screw thread may be eliminated at the middle in the longitudinal direction and at a position corresponding to the lead screw support 931 to constitute a section of a polished rod where the lead screw 932 is rotatably supported on the lead screw support 931 by a bearing or the like.

As mentioned above, the reel 92 is driven by the actuator shaft 10, since there is a driving gear 923 at each end of the reel 92, when the reel 92 rotates, the driving gear 923 rotates accordingly, the two driving gears 923 drive a pair of driven gears 934 synchronously, the pair of driven gears 934 drive a pair of screw rods 932, the pair of screw rods 932 drive a cord-arranging movable socket 933 in threaded engagement with the screw rods 932, and the movement of the cord-arranging movable socket 933 causes a pair of blind lifting/pulling cords 81 to be orderly and uniformly arranged on the reel 92, for which reference is made to the schematic diagrams of fig. 1 and 6.

The driving gear 923 may be directly fixed to both ends of the drum 92, or the driving gear 923 may be formed in the middle of a driving gear shaft, one end of the driving gear shaft is tightly inserted into the end of the drum 92 (because the drum 92 is hollow), and the other end of the driving gear shaft is fixedly inserted into the drum end pivot support bearing 9131, in which case the actuator acting shaft fitting hole 9221 is shifted to the axial center of the driving gear shaft.

Preferably, a pair of key projections 918 (i.e., "key projections") may be formed in the longitudinal direction of the spool 92, and the key projections 918 are spaced apart by 180 ° around the circumferential direction of the spool 92, i.e., in a face-to-face positional relationship. The pair of key protrusions 918 has a good anti-floating function for the pair of blind lifting pulling ropes 81, and provides a condition for realizing key fixation for the driving gear 923 (see fig. 5 in particular).

As shown in fig. 5 and 6, a supporting blind lifting cord guide pulley 916 is rotatably provided below the pair of reel supporting bases 91 corresponding to the screw end supporting bearing insertion hole 914.

As shown in fig. 5, a screw rod supporting seat hole 9311 penetrating from one side to the other side of the screw rod supporting seat 931 or being partitioned in the middle is formed in the upper portion of the screw rod supporting seat 931, opposite ends of the pair of screw rods 932 are rotatably supported in the screw rod supporting seat hole 9311, and the bottom of the screw rod supporting seat 931 is fixed to the middle of the length direction of the lower connecting fixing plate 912 of the supporting seat through a screw rod supporting seat fixing screw 9312; the screw threads of the pair of screw rods 932 are formed in opposite directions to each other.

Since the width of the blind 8 shown in fig. 1 is relatively small, i.e. narrow, it has already been mentioned above that: two blind lifting pulling ropes 81 are provided, namely, a pair (two in total) of winding drum supporting seats 91, one winding drum 92, two rope arranging devices 93 are provided, namely, a pair, two blind turning ladder ropes 82 are provided, and a pair of blind turning devices 93 are provided. With respect to the above-mentioned positioning of the pair of reel supporting seats 91, the positioning can be performed by means of the supporting seat frame fixing slots 915, and specifically, if the supporting seat frame fixing slots 915 are only provided on the rear sides of the pair of reel supporting seats 91, during assembly, an assembly worker needs to carefully align the side having the supporting seat frame fixing slots 915 with the above-mentioned protruding strips (not shown in the figure) on the rear wall plate of the upper cross frame strip 74, so as to ensure that the supporting seat frame fixing slots 915 on the pair of reel supporting seats 91 are in clamping fit with the protruding strips on the rear wall plate of the upper cross frame strip 74; because the reel supporting seat 91 can be installed by rotating 180 degrees (installed in a front-back exchange way), the supporting seat frame fixing clamping groove 915 at the front side of the reel supporting seat 91 can be clamped and matched with the convex strip on the rear wall plate of the upper cross frame strip 74, so that the problem of installation direction or azimuth error of a pair of reel supporting seats 91 possibly occurring in the assembling process can be avoided. Of course, if the cover 7411 also has a protrusion at a position corresponding to the support frame fixing groove 915 on the front side of the pair of reel supports 91, the support frame fixing groove 915 on the front side of the pair of reel supports 91 can be engaged with a protrusion (not shown) on the cover 7411 for shielding the upper horizontal frame cavity 741, so that the pair of reel supports 91 can be engaged in the front and rear direction, in which case, the front and rear sides of the pair of reel supports 91 must have the support frame fixing grooves 915. As can be seen from the foregoing, at least one side of the pair of reel supporting bases 91 is provided with a supporting base frame fixing groove 915.

A locking protrusion 9417 is formed at the bottom of the base 941, and a locking protrusion slot 94171 is formed around the locking protrusion 9417, and the locking protrusion slot 94171 is locked with the bottom wall of the upper cross frame strip cavity 741.

Continuing to refer to fig. 8 and 9, a pair of half-sectional walls 9412 corresponding to each other are formed at a lower portion of the base 941, a steered wheel shaft head support groove 94121 is formed at each of opposite sides of the half-sectional walls 9412 and at positions corresponding to each other, and the shaft head of the steered wheel shaft 9431 is supported in the steered wheel shaft head support groove 94121; a direction-changing wheel bearing cavity 9432 is formed at each end of the direction-changing wheel 943 of the blind lifting traction rope, a direction-changing wheel rotating support bearing 94321 is arranged in the direction-changing wheel bearing cavity 9432, and the non-rotating inner ring of the direction-changing wheel rotating support bearing 94321 is sleeved and fixed on the direction-changing wheel shaft 9431; a pair of base engaging grooves 9413 are formed in the front middle and rear middle of the base 941 in the height direction and at positions corresponding to each other; a traction rope passing hole 9414 is formed at a lower portion of the base 941 and on a wall between the pair of half walls 9412, and the traction rope passing hole 9414 corresponds to the above-mentioned blind lifting traction rope bend wheel 943; a wheel axle head support cavity 9415 is formed on each of walls on both sides (i.e., left and right sides in the position shown in fig. 8 and 9) corresponding to the upper portion of the base 941, and the axle head 94212 of the wheel axle 9421 of the ladder rope overturning wheel 942 is rotatably supported in the wheel axle head support cavity 9415; a pair of limit seat engaging leg engaging grooves 9416 are formed at the top of each of the opposite sides of the base 941, and a pair of limit seat engaging legs 9441 are formed at each of the opposite sides of the limit seat 944 of the ladder rope winding wheel and at positions corresponding to the pair of limit seat engaging leg engaging grooves 9416, respectively, and the pair of limit seat engaging legs 9441 are engaged with the pair of limit seat engaging leg engaging grooves 9416; a pair of stopper claws 9442 for preventing the curtain slat overturning ladder cord from being biased extend downward on both sides of the ladder cord overturning wheel stopper 944.

With continued reference to fig. 8 and 9 in conjunction with fig. 1, the applicant does not repeat the description since the pair of base engaging grooves 9413 mentioned above function exactly the same as the support base frame securing grooves 915 mentioned above. When the pair of curtain sheet turnover devices 94 are disposed in the upper cross frame bar cavity 741 of the upper cross frame bar 74 shown in fig. 1, as described above, the locking protrusion grooves 94171 formed on both sides of the locking protrusion 9417 at the bottom of the base 941 are engaged with the bayonet formed on the bottom wall of the upper cross frame bar cavity 741. The pair of blind lifting pulling ropes 81 pass through the pulling rope through holes 9414 and the blind lifting pulling rope direction-changing wheels 943 and then reach the supporting seat blind lifting pulling rope guide wheels 916. Since the blind lifting/lowering traction rope bend wheel 943 is rotatably supported on the bend wheel shaft 9431 by the pair of bend wheel rotation support bearings 94321, the blind lifting/lowering traction rope bend wheel 943 can freely rotate, so that the resistance is remarkably reduced, the severe friction between the pair of blind lifting/lowering traction ropes 81 and the blind lifting/lowering traction rope bend wheel 943 can be avoided, and the advantages of small operation resistance and high speed can be realized during manual operation or during the motor driving operation.

The structural system of the lifting and turning actuating mechanism 9 of the venetian blind adopts the winding drum 92 and the rope guiding device 93, and the advantages thereof are at least as follows: one is that the rope arrangement device 93 driven by the winding drum 92 is helpful to wind the pair of blind lifting pulling ropes 81 on the winding drum 92 or exit from the winding drum 92 in an active manner, so as to avoid rope mess, rope biting and even knotting; secondly, the stability and consistency of the rope winding and unwinding of the pair of lifting traction ropes 81 of the blind curtain can be ensured, so that the situation that the curtain sheet 84 of the blind curtain 8 jumps can be avoided; thirdly, the friction degree of the pair of blind lifting traction ropes 81 in the rope winding and unwinding process is obviously reduced, so that the expected service life is ensured; fourthly, because the curtain turning device 94 is additionally provided with the ladder rope turning wheel limiting seat 944, the escape of the ladder rope turning wheel 942 can be avoided, and the hanging reliability of the pair of curtain turning ladder ropes 82 in the use state is ensured; fifthly, because the middle part of the front side and the middle part of the rear side of the base 941 in the height direction and the corresponding positions respectively form a pair of base clamp grooves 9413, the base 941 can be matched with the raised strips on the rear wall plate of the upper cross frame strip 74 of the window body 7 in a use state, the stability of the base 941 is ensured, and the front, rear, left and right deviation and up and down flutter are avoided; sixth, since the blind lifting/lowering traction rope bend wheel 943 is rotatably mounted on the base 941 via the bend wheel rotation support bearing 94321 and the bend wheel shaft 9431, the blind lifting/lowering traction rope bend wheel 943 can rotate freely, friction between the pair of blind lifting/lowering traction ropes 81 and the bend wheel shaft can be significantly reduced, and not only the operation resistance is small, but also the life of both can be effectively prolonged.

As can be seen from the above description, the actuating shaft 10 is driven by the driven transmission mechanism 5 of the magnetic column disposed at the right end of the upper horizontal frame 74, the rope-turning wheel 942 is driven by the actuating shaft 10, so that the curtain 84 is turned by the pair of curtain-turning ropes 82, and similarly, the drum 92 is driven by the actuating shaft 10, the pair of driven gears 934 is driven by the driving gear 923 at the two ends of the drum 92, the pair of screw rods 932 is driven by the pair of driven gears 934, the pair of rope-guiding movable screw sockets 933 are driven by the pair of screw rods 932, because the pair of blind lifting traction ropes 81 pass through the rope-arranging moving screw sleeve blind lifting traction rope guide wheels 9331 arranged on the pair of rope-arranging moving screw sleeve seats 933 respectively and then the end parts of the blind lifting traction ropes are fixed with the fixer fixing lugs 9211 of the fixer 921 of the blind lifting traction rope end, so that the blind lifting rope 81 can be wound on the winding drum 92 or withdrawn from the winding drum 92 as required.

The housing 1 of the present invention is hung on the upper right of the inner glass 72 by the hanging plate 141 and the magnetic column driving transmission mechanism 3 disposed in the housing cavity 11 corresponds to the magnetic column driven transmission mechanism 5, and the housing magnetic through groove 13 corresponds to the support magnetic through groove 42, so that the two driving magnetic columns of the structural system of the magnetic column driven transmission mechanism 5 are magnetically engaged (magnetic attraction) with the two driven magnetic columns, i.e., the left magnetic column 52 and the right magnetic column 53, of the structural system of the magnetic column driven transmission mechanism 5. As mentioned above, when the tubular motor 2 is operated by the wireless signal receiving controller 6 after receiving the signal from the wireless remote control signal transmitter 30 and the magnetic column driving transmission mechanism 3 is driven by the tubular motor shaft 21, the magnetic column driving transmission mechanism 3 drives the magnetic column driven transmission mechanism 5, and finally the shutter 8 is lifted and the shutter piece 84 is turned over as required by the aforementioned actuating mechanism acting shaft 10. The operating power supply of the wireless signal reception controller 6 is supplied from the battery 201 of the power supply support mechanism 20. When the storage battery 201 is short of charge, the charging socket 202 charges the storage battery, and the charging socket 202 provides charging power through a charging connector connected with the power supply. The working power supply of the wireless remote control signal transmitter 30 adopts a dry battery (the action mechanism is as that of a television or an air conditioner remote controller seen in daily life).

Since the solar photovoltaic power generation apparatus 2031 is used in this embodiment, the charging socket 202 can be eliminated, and the charging socket mating hole 171 is changed to a solar photovoltaic power generation apparatus line inlet through which the line 20311 passes. The rest is the same as described in example 1.
