Description

Technical Field

[0001] The utility model relates to the technical field of sunshade devices, in particular to a magnetic transmission device and a hollow built-in louver glass. Background Art

[0002] Hollow built-in blinds are products used in door, window and curtain wall shading. They have the characteristics of high cost performance, good sunshade and energy saving effect and long service life. There are two types of hollow built-in magnetic blinds and hollow built-in electric blinds on the market. The hollow magnetic control blinds use magnetic control sliders to realize the lifting and turning of the blinds. The hollow built-in blinds are driven by a motor to drive the corner seat to drive the belt to run, the belt drives the external operating magnet, and the external operating magnet drives the internal operating magnet of the hollow blinds to run to realize the lifting and turning of the blinds, thereby realizing the adjustment of indoor light through lifting and turning.

[0003] Traditional hollow built-in blinds seal the motor together inside the hollow glass. Among them, the motor of the hollow built-in electric blinds is a built-in motor, that is, the motor is inside the hollow cavity. In summer, the temperature inside the hollow cavity of the curtain wall glass can reach 85°C. The thermal protection of the motor itself will stop working at 70°C, which makes the hollow blinds unusable in the hottest weather. In addition, the built-in motor is prone to aging in the hollow cavity over time. The hollow cavity is sealed and it is not convenient to replace, which makes the replacement cost high, causing some users to worry about maintenance issues.

[0004] Therefore, external motor systems began to appear, but the existing external motors used a large number of magnets, which resulted in high costs and uneven transmission between the external motor and the internal mechanism. Utility Model Content

[0049] The active mechanism 100 and the passive mechanism 200 are symmetrically arranged on both sides of the glass 300, and the central axis of the active mechanism 100 and the central axis of the passive mechanism 200 do not coincide with the central axis of the glass 300;

[0050] The motor 102 drives the first magnetic member 600 to rotate, and the first magnetic member 600 forms a magnetic fit with the second magnetic member 700 through the glass 300 .

[0051] This embodiment provides a magnetic transmission device, which adopts parallel transmission between an active mechanism 100 and a passive mechanism 200, and has a simpler structure. In addition, the magnetic transmission device adopts an eccentric structure, and the number of magnetic pole elements is not affected by the cavity size of the insulating glass, so the number of magnetic pole elements used is smaller.

[0052] In this embodiment, if Figure 3 As shown, the active mechanism 100 also includes an outer magnet sleeve 101, a first frame 103, a motor bracket 104 and a first end cover 106.

The first main axis passes through a channel formed by splicing the first magnetic pole element 601 and the second magnetic pole element 602.

[0056] The first magnetic pole element 601 is an S pole, and the second magnetic pole element 602 is an N pole, or the first magnetic pole element 601 is an N pole, and the second magnetic pole element 602 is an S pole.

The second frame 201 and the second end cover 202 form a second installation space, and the second magnetic member 700 is disposed in the second installation space.

[0058] The passive mechanism 200 further includes a first gear and a second gear (not shown in the figure) that are meshed and transmitted. One end of the second magnetic member 700 is connected to the first gear, and one end of the reducer 203 is connected to the second gear.

[0059] Specifically, the second magnetic member 700 includes a second main axis (not shown in the figure) and an arc-shaped third magnetic pole element 701 and an arc-shaped fourth magnetic pole element 702 arranged around the second main axis. The third magnetic pole element 701 and the fourth magnetic pole element 702 are spliced ​​into an annular magnetic member, and the two sides of the third magnetic pole element 701 are in contact with the fourth magnetic pole element 702. Figure 5 As shown, there are two third magnetic pole elements 701 and two fourth magnetic pole elements 702. The two side surfaces of the third magnetic pole element 701 are respectively fitted with the side surfaces of the fourth magnetic pole element 702. The second main axis passes through a channel formed by splicing the third magnetic pole element 701 and the fourth magnetic pole element 702.

[0060] The third magnetic pole element 701 is an S pole, and the fourth magnetic pole element 702 is an N pole, or the third magnetic pole element 701 is an N pole, and the fourth magnetic pole element 702 is an S pole.

[0061] As can be seen from the above, the magnetic pole element in this embodiment adopts a spliced ​​ring structure, the magnetic poles are densely packed and in the same direction, and the transmission is more stable.

[0064] Embodiment 2

[0065] The difference from the first embodiment lies in the number of reducers 203 .

It should be noted that the central axis of the active mechanism 100 and the central axis of the passive mechanism 200 still do not coincide with the central axis of the glass 300.

[0067] It can be seen from the above that the second magnetic component 700 can be used for single output or dual output, and of course can also be used in combination.

[0068] The working principle of this embodiment is basically the same as that of the first embodiment, and will not be described in detail here.
