Description

Technical Field

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

[0002] Today's large commercial buildings mostly use transparent enclosure structures such as glass curtain walls. Although this type of enclosure structure allows sufficient sunlight into the room, it is not conducive to the privacy protection of people indoors due to the large light-transmitting area, and too much sunlight can easily cause glare and other discomfort to people indoors.

[0003] In order to enhance privacy protection and reduce discomfort such as glare, people generally choose to apply film on transparent enclosure structures or use blinds that can adjust the light intensity to block the light.

[0004] However, on the one hand, the traditional method of sticking film on the bottom of the transparent enclosure structure can achieve the purpose of reducing glare and protecting privacy, but it cannot flexibly adjust the indoor lighting; on the other hand, most of the blinds on the market are of the retractable type with the top fixed and the bottom lifted, and generally speaking, the reflected light from the ground is stronger. This type of blinds with the top fixed and the bottom lifted can block the reflected light from the ground only when the transparent enclosure structure is completely blocked, but this will affect the visual effect. While maintaining a good visual effect, it cannot effectively block the reflected light from the ground, and discomfort phenomena such as glare are not effectively reduced. Summary of the invention

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, the present invention provides an embodiment of a rising type blind, comprising a fixed frame 1, a lifting and pulling mechanism 2 and a blind 3, Figure 3 The fixed frame 1 is provided with a first accommodating cavity, in which a rack 4 and a sliding rail 5 are arranged in parallel, and the sliding rail 5 is connected to an external power supply; the lifting and traction mechanism 2 includes a driving motor 6 and a slider 7, combined with Figure 4 The slider 7 is provided with a pressure wheel 8, a gear 9 and a conductive component, combined with Figure 5-8 One end of the conductive component is in contact with the sliding rail 5, and the other end is connected to the driving motor 6; the pressure wheel 8 is against the back of the rack 4, the gear 9 is meshed with the rack 4, and the rotating shaft 61 on the driving motor 6 drives the gear 9 to rotate and drives the slider 7 and the driving motor 6 to rise and fall along the rack 4; the venetian blind 3 is arranged in the first accommodating cavity, and its top is connected to the lifting traction mechanism 2, and the lifting traction mechanism 2 pulls the venetian blind 3 to rise and fall along the rack 4.

[0037] In this embodiment, a sliding rail 5 and a rack 4 are arranged in parallel in the first accommodating cavity of the fixed frame 1, and the conductive component of the slider 7 in the lifting and traction mechanism 2 is connected to the driving motor 6 and abuts against the sliding rail 5 to supply power to the driving motor 6 in real time; at the same time, the pressure wheel 8 in the slider 7 presses the rack 4 on the gear 9 to make the gear 9 mesh with the rack 4, and the rotating shaft 61 of the driving motor 6 drives the gear 9 to rotate, so that the lifting and traction mechanism 2 is lifted and lowered as a whole along the rack 4, and the lifting and traction mechanism 2 drives the blinds 3 at the bottom thereof to unfold upward when the lifting and traction mechanism 2 rises, and drives the blinds 3 at the bottom thereof to fold downward when the lifting and traction mechanism 2 descends. The indoor lighting can be flexibly adjusted, and since the lifting and traction mechanism 2 drives the top of the venetian blind 3 to lift and lower, the height of the top of the venetian blind 3 is mainly adjusted during lifting and lowering, and the bottom of the venetian blind 3 always plays a role in blocking the reflected light from the ground. While maintaining a good visual effect, it can protect the privacy of people indoors and avoid glare and other discomforts. In addition, the present embodiment uses a drive motor 6 to realize the lifting and flipping of the venetian blind 3. Its structure is simple, and the drive motor 6 is powered by the conductive component in the slider 7 and the sliding rail 5. The power supply method of the drive motor 6 is stable, and the working reliability of the venetian blind 3 is high.

[0038] The driving motor 6 of this embodiment is a motor with current limiting control function, that is, when the lifting and traction mechanism 2 is lifted and lowered into place, the current of the driving motor 6 increases sharply. When the current exceeds the limit value, the driving motor 6 stops moving. At this time, due to the friction between the rack 4 and the pressure wheel 8 and the gear 9, the lifting and traction mechanism 2 stays in this position.

[0039] Specifically, the fixed frame 1 of this embodiment includes a top frame 11, a bottom frame 12, a side frame 13 and a corner connector 14, one end of the corner connector 14 is provided with a first pin 141, the other end of the corner connector 14 is provided with a second pin 142, the two ends of the top frame 11 and the bottom frame 12 are respectively provided with first slots 111 and 121 adapted to the first pin 141, and the two ends of the side frame 13 are respectively provided with second slots 131 adapted to the second pin 142.

[0040] The sliding rail 5 of this embodiment specifically includes a sliding rail body 51 and a conductive strip 52.

The conductive strip 52 is clamped in the sliding rail body 51, and the conductive strip 52 is connected to an external power supply. A guide groove 132 is provided in the side frame 13, and the sliding rail body 51 is arranged at the bottom of the guide groove 132. A pressing block 141 is provided on the corner connector 14, and the two ends of the rack 4 are fixed to the corner connector 14 through the pressing block 141.

[0041] The lifting and traction mechanism 2 also includes a mounting seat 21 and a slot cover plate 22. The mounting seat 21 cooperates with the slot cover plate 22 to form a second accommodating chamber. The drive motor 6 is arranged in the second accommodating chamber, and the slider 7 is arranged at both ends of the second accommodating chamber. The conductive components in the slider 7 of this embodiment specifically include a conductive rod 01 and a compression spring 02. The slider 7 is provided with a slide groove 71 and a compression spring accommodating groove 72. The slide groove 71 runs through the slider 7 and communicates with the compression spring accommodating groove 72. The conductive rod 01 is slidably arranged in the slide groove 71. One end of the conductive rod 01 is in sliding contact with the slide rail 5, and the other end is connected to the drive motor 6. The compression spring 02 is sleeved outside the conductive rod 01 and is arranged in the compression spring accommodating groove 72. The end of the compression spring 02 close to the drive motor 6 abuts against the compression spring accommodating groove 72, and the end away from the drive motor 6 abuts against the conductive rod 01. In order to reduce the resistance of the lifting and traction mechanism 2 during the lifting process, a conductive pulley 03 is preferably provided at one end of the conductive rod 01 in this embodiment that is in sliding contact with the sliding wire rail 5. Under the tension of the compression spring 02, during the lifting and traction mechanism 2 is lifted and lowered in the side frame 13, the wheel surface of the conductive pulley 03 and the surface of the sliding wire rail 5 in the side frame 13 always maintain conductive contact, thereby providing stable power supply to the drive motor 6 and making the lifting and traction mechanism 2 more continuous and stable in lifting and lowering movement.

[0042] In order to make the lifting and traction mechanism 2 more stable in the lifting and lowering of the side frame 13 , the slider 7 of this embodiment is provided with rollers 73 , and the rollers 73 are respectively in contact with the inner walls of both sides of the guide groove 132 .

[0043] The venetian blind 3 of this embodiment includes a blind slat 31 and a ladder rope 32. The rotating shaft 61 is provided with a flap wheel 611. The top of the ladder rope 32 is connected to the flap wheel 611. The blind slat 31 is mounted on the ladder rope 32, and the two ends of the blind slat 31 extend into the guide groove 132. In addition, the venetian blind 3 also includes a guide rope 33 for providing positioning for the blind slat 31. The blind slat 31 is provided with a through hole 311, and the slider 7 is provided with a wire groove 74. The bottom of the guide rope 33 is fixed to the corner connector 14 of the bottom frame 12, and the top of the guide rope passes through the through hole 311 of the blind slat 31 and the wire groove 74 in sequence, and is fixed to the corner connector 14 of the top frame 11. Fig. 9 In order to reduce the resistance of the lifting and traction mechanism 2 during the lifting process, a guide wheel 75 is provided at the corner of the wire groove 74, and the guide rope 33 contacts the surface of the guide wheel 75.

[0044] In order to avoid light leakage caused by the through holes 311 on the curtain piece 31, in this embodiment, the through holes 311 are set at the two ends of the curtain piece 31 extending into the guide groove 132. The through holes 311 are just blocked by the side frames 13. When the curtain piece 31 is flipped to the closed state, indoor and outdoor light will not directly pass through the through holes 311.

[0045] In summary, the implementation of the present invention has the following beneficial effects:

[0046] 1. When the lifting and traction mechanism 2 rises, it drives the blinds 3 at the bottom to unfold upwards, and when the lifting and traction mechanism 2 falls, it drives the blinds 3 at the bottom to fold downwards, so that the indoor lighting can be flexibly adjusted. Since the lifting and traction mechanism 2 drives the top of the blinds 3 to move up and down, the height of the top of the blinds 3 is mainly adjusted during the lifting and lowering. The bottom of the blinds 3 always plays a role in shielding the reflected light from the ground, which can protect the privacy of people indoors and avoid glare and other discomforts while maintaining a good visual effect.

[0047] 2. The sliding wire rail 5 is connected to an external power supply. The sliding wire rail 5 and the rack 4 are arranged in parallel. During the lifting and lowering process of the lifting and traction mechanism 2, the conductive components in the slider 7 cooperate with the sliding wire rail 5 to provide real-time power supply to the drive motor 6. The power supply mode of the drive motor 6 is stable, and the working reliability of the venetian blind 3 is high;

[0048] 3. The structure is simple, and one driving motor 6 can realize the lifting and flipping of the blind 3;

[0049] 4. The through holes 311 of the curtain piece 31 are arranged at the two ends of the curtain piece 31 extending into the guide groove 132 of the side frame 13, which can completely solve the light leakage problem of the through holes 311, and the light shielding effect and privacy protection effect are better.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention.
