Description

Magnetic transmission manual driving device for 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 magnetic transmission manual driving device for a shutter built in hollow glass.
Background
The aforementioned hollow glass built-in louver mainly refers to, but is not absolutely limited to, a double-layer hollow glass built-in louver (hereinafter the same applies), and for example, there are also a plurality of layers such as three-glass two-chamber hollow glass built-in louver. 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 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 known 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), 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 for the weak such as the young and the old; 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 together with the motor, the non-metallic isolator, 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 piece in the cavity is not perfect enough, for example, once the external magnetic controller is subjected to impact or collision 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 a user, the problem of taking measures is often generated; thirdly, although the patent in paragraph 0028 mentions the content of the power line connecting the power source, it also does not give any hint 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 indispensable components in the housing along with the motor, etc.; fourthly, according to the information of the motor mentioned in the specification, the driving mode of the patent is required to depend on a power supply, thereby causing the structure to be complicated, increasing the cost and increasing the maintenance difficulty in daily use, for example, as a user can not objectively perform substantive repair on a controller for controlling the operation of the motor and the motor itself; when the width of the venetian blind is large, especially the window width (also called "window width") of modern buildings is relatively large and tends to increase continuously, so that the width (also called "door width") of the venetian blind matched with the venetian blind is correspondingly increased, and therefore, the motor volume and the power of the structural system of the external electro-dynamic magnetic controller called in the patent are necessarily increased, and the diameter and the number of the magnetic columns are simultaneously increased under the condition of increasing the motor and the power, so that the volume of the whole external magnetic transmission motor controller is increased, and the manufacturing cost is obviously increased, and the economy is lost.
The bead chain driven double-layer hollow glass built-in shutter provided by the Chinese invention patent CN105041172B reasonably makes up the defects of the hollow glass built-in shutter in the prior art summarized in the background field of the specification, and objectively realizes the four advantages stated in the technical effect field of the specification. However, the patent has the disadvantage of relatively complicated structure due to many links in motion transmission, and also has the fear that the limbs of people, especially the neck of the young people, may be tied due to the free swinging of the long and ring-shaped bead chain rope (commonly called as "bead chain", the same shall apply hereinafter). In addition, as for national standard requirements, the annular curtain pull rope (including the pull bead chain) is not allowed to freely float (shake) in a non-positioning mode so as to ensure safety.
In view of the above-mentioned prior art, there is a need for improvement, for which the applicant has made an active and advantageous design, against the background of which the solution to be described below is made.

Referring to fig. 6 in conjunction with fig. 1, since the structure of the magnetic pole driving transmission mechanism 3 is the same as that of the magnetic pole driven transmission mechanism 5, the applicant only describes the structure of the magnetic pole driven transmission mechanism 5 in detail below, and in this embodiment, the magnetic pole direction deflection angle of the magnetic pole driven transmission mechanism 5 is different from the magnetic pole direction deflection angle of the magnetic pole driving transmission mechanism 3, and the difference in the deflection angles is to ensure that the magnetic pole polarities between the magnetic pole driving transmission mechanism 3 and the magnetic pole driven transmission mechanism 5, such as the N pole and the S pole, are attracted or the S pole and the N pole are the same.

In the present embodiment, the blind acting shaft 30 illustrated in fig. 7 and 8 is fitted into the blind acting shaft insertion hole 5411, and if the entire magnetic pole driven transmission mechanism 5 is turned down by 180 °, the blind acting shaft 30 is fitted into the blind acting shaft insertion hole 5511.
The applicant needs to state that: if, in a form-only and insubstantial variation, the power axle torque multiplying mechanism 2 (actually, a "speed reducing mechanism") is transferred to the left end of the aforementioned magnetic cylinder driven transmission mechanism 5, i.e., disposed in the magnetic cylinder driven transmission mechanism accommodating chamber 41 at a position corresponding to the left side of the aforementioned left support axle seat fixing base 541, and the aforementioned regular polygon connector 2713 is inserted into the actuator acting shaft insertion hole 5411, the blind acting shaft 30 is inserted into the transition connection axle hole 2313, and the aforementioned transition connection axle 20 is inserted into the pull bead chain drive axle connection hole 731, it should be regarded as an equivalent technical means. Since the technical effect brought about by this variation is the same, in particular: due to the increase of the output torque, the volume and the number of the magnetic columns can be reduced under the condition of the blind 8 with the same breadth, and the blind 8 with a larger breadth, namely a larger width, can be driven under the condition of the same volume and number of the magnetic columns. As is clear from the above description, when the width of the blind 8 is not changed, the output torque is significantly increased as compared with the case where there is no speed reducer, that is, as compared with the case where there is no power-wheel-shaft-torque-increasing mechanism 2, and thus a magnetic pole having a correspondingly reduced volume can be applied.

And because the diameters of the left support bearing 56 and the right support bearing 57 are larger than the diameter of the magnetic column sleeve 51, on one hand, the whole magnetic column driven transmission mechanism 5 can be sufficiently positioned in the magnetic column driven transmission mechanism accommodating cavity 41, and on the other hand, the magnetic column sleeve 51 can be prevented from being in friction or contact with the cavity wall of the magnetic column driven transmission mechanism accommodating cavity 41, namely, a reasonable gap is kept between the magnetic column sleeve 51 and the cavity wall of the magnetic column driven transmission mechanism accommodating cavity 41.

The supporting seat 4 of the present invention is disposed at the right end of the upper horizontal frame cavity of the upper horizontal frame of the frame 101, the magnetic column driven transmission mechanism 5 in the supporting seat drives the blind acting shaft 30, and the blind acting shaft 30 drives the blind turning and blind lifting actuator 102, so as to turn the blind of the blind 8 shown in fig. 7 or lift the blind 8 as required. The housing 1 is hung on the upper right of the inner glass 103 through the hanging plate 141, the magnetic column driving transmission mechanism 3 arranged 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 respectively in magnetic fit (magnetic attraction) with the two driven magnetic columns, namely the left magnetic column 52 and the right magnetic column 53, of the structural system of the magnetic column driven transmission mechanism 5. Also shown in fig. 7 is a blind lift cord arranger 1021 of the structural architecture of the blind blade flipping and blind lift actuator 102 and a locking mechanism 6 (also referred to as a "clutch mechanism", the same applies hereinafter).
Referring to fig. 8 in combination with fig. 7, the locking mechanism 6 is disposed near the left end of the rectangular frame 101, i.e. at the left end of the blind turning and blind lifting actuator 102, the locking mechanism 6 includes a magnet block seat 61, a magnet block 62 and a spline 63, a magnet block seat sliding slot 611 is formed at each of the front side and the rear side of the lower portion of the magnet block seat 61, the magnet block seat sliding slot 611 is slidably engaged with the bottom plate of the upper cross frame cavity of the upper cross frame of the frame 101, specifically, a sliding cavity is formed on the bottom plate of the upper cross frame cavity, the magnet block seat sliding slot 611 of the magnet block seat 61 is slidably engaged with the corresponding cavity wall of the sliding cavity, the blind turning and blind lifting actuator 102 is also disposed in the upper cross frame cavity of the upper cross frame and is sealed by a frame cavity sealing sheet 1011, a magnet block seat locking column 612 extends from the center position of the left side of the magnet block seat 61, a locking column spline hole 6121 is arranged at the axial center of the magnet block seat locking column 612, the magnet block 62 is embedded in the magnet block seat cavity of the magnet block seat 61, a magnet block hole (not shown in the figure) penetrating from the left side to the right side of the magnet block 62 is formed on the magnet block 62 and at the position corresponding to the locking column spline hole 6121, the magnet block hole corresponds to a shutter curtain acting shaft abdicating hole (not shown in the figure) arranged at the central position of the right side of the magnet block seat 61, and the spline 63 is fixed at the left end of the shutter curtain acting shaft 30, specifically: the left end of the blind acting shaft 30 sequentially passes through the blind acting shaft abdicating hole, the magnet block hole and the locking column spline hole 6121 in the central position of the right side surface of the magnet block seat 61 from right to left and extends towards the direction of the spline 63, so that the spline 63 and the end part of the left end are fixed. In fig. 8, a spline fixing head 631 is shown at the left end of the spline, and a locking screw hole 6311 is formed in the spline fixing head 631, and a locking screw 63111 is screwed into the locking screw hole 6311 to lock the left end of the shutter action shaft 30 inserted into the spline 63, that is, to fix the spline 63 to the left end of the shutter action shaft 30.
As can be seen from the above configuration, when the magnet block 62 and the magnet block holder 61 move in the direction toward the spline 63 and move to the extent that the locking cylindrical spline hole 6121 and the spline 63 are engaged with each other, the shutter operation shaft 30 is in the locked state, and when the magnet block 62 and the magnet block holder 61 move in the direction away from the spline 63 and move to the extent that the locking cylindrical spline hole 6121 and the spline 63 are disengaged from each other, the shutter operation shaft 30 is in the unlocked state.
The applicant needs to state that: since the width or breadth of the blind 8 shown in fig. 7 is relatively small or narrow, only one blind lifting/lowering rope guider 1021 of the structural system of the blind blade turning and blind lifting actuator 102 is used, and the locking mechanism 6 is disposed at the left end of the upper cross bar. However, if the window 10 is large in size, the width of the rectangular frame 101 and the blind 8 is increased accordingly, and the number of the blind lifting rope winding devices 1021 is increased to two, in this case, the locking mechanism 6 is shifted to the middle of the upper frame bar, i.e., between the two blind lifting rope winding devices 1021, so as to lock the two blind lifting rope winding devices 10121 at the same time.
After the installation of the blind 8 is completed, i.e., the entire window 10 is completed, the blind 8 needs to be lifted (retracted) upward according to the manufacturing and repair specifications, and the flow is allowed to proceed to the next process. Therefore, after the blind 8 is installed, if it is required to ensure its retracted state, the on-line operator holds (holds) a locking magnet and aligns the magnet block 62 with the inner glass 103, and pulls the magnet block 62 and the entire magnet block holder 61 to the left by the locking magnet, so that the spline hole 6121 of the locking cylinder is engaged with the spline 63. Since the shutter shaft 30 is substantially locked in this state, the shutter 8 does not fall down abnormally, and the description thereof is omitted. In a further case, when the maintenance personnel are going to the user for repair, it is also necessary to first bring the blind 8 into the upward-raised state and lock the blind action shaft 30 in the same manner as described above. In another case, the blind 8 is also required to be in an upward retracted state during the transportation of the product, so as not to be damaged by shaking.
The applicant has briefly described the working conditions of the invention with reference to fig. 1 to 8, and in normal use, the locking mechanism 6 shown in fig. 7 and 8 is in the unlocked (unlocked) condition of the blind action shaft 30. The user pulls the pull bead chain 71 of the structural system of the bead chain manual operation mechanism 7, the pull bead chain driving wheel 72 is driven by the pull bead chain driving wheel 71, the pull bead chain driving wheel shaft 73 is driven by the pull bead chain driving wheel shaft 73, the power output gear shaft 271 (essentially, "power input gear shaft") is driven by the pull bead chain driving wheel shaft 73, the power output gear shaft 271 drives the reduction gear shaft pinion 26 through the power output gear 27, the reduction gear shaft 24 is driven by the reduction gear shaft, the driving gear 23 is driven by the reduction gear shaft bull gear 25, the driving gear shaft 231 is driven by the driving gear shaft 231, the transition connecting shaft 20 connected with the transition connecting shaft hole 2313 is driven by the driving gear shaft 20, the magnetic column driving transmission mechanism 3 rotates, the magnetic column driven transmission mechanism 3 magnetically attracts the magnetic column driven transmission mechanism 5, the magnetic column driven transmission mechanism 5 drives the blind sheet turnover and blind lifting actuator 102 through the blind acting shaft 30, thereby realizing the lifting of the blind 8 or the turning of the blind sheet. The raising or lowering of the blind 8 depends on the operator pulling clockwise or counterclockwise the pull-bead chain 71.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
