Description

Technical Field

[0001] The present application relates to the field of curtains, and in particular to an electric honeycomb curtain with adjustable shielding position. Background Art

[0002] Honeycomb blinds are also called accordion blinds. They are shaped like an organ and can be opened or folded. They are called honeycomb blinds because the cross-sectional shape of a single tube imitates the hexagonal structure of a honeycomb in nature.

[0003] Honeycomb blinds are widely used in interior decoration because of their good thermal insulation and sound insulation effects. Common honeycomb blinds are divided into two categories: manual and electric. Electric honeycomb blinds are provided with a window frame, in which the honeycomb blinds are installed. A motor is provided in the window frame, which drives the curtain chain of the honeycomb blinds to rotate and then drives the honeycomb blinds to open or lower.

[0004] The upper end of common electric honeycomb blinds is fixed. When the user needs lighting through the window, if only lighting is needed below the window, only part of the curtain can be raised. However, when lighting is needed above the window, the curtain needs to be raised to above the window to achieve lighting on the upper part of the window. The requirement of lighting only the upper part of the window while the lower part is still blocked cannot be achieved. Summary of the invention

[0005] In order to solve the problem that the conventional electric honeycomb blind is rolled up from bottom to top, resulting in a single window shielding mode, the present application provides an electric honeycomb blind with adjustable shielding position.

[0006] The present application provides an electric honeycomb blind with adjustable shielding position, which adopts the following technical solution:

[0007] An electric honeycomb curtain with adjustable shielding position comprises a rectangular frame and a honeycomb curtain, wherein a first positioning rod and a second positioning rod are slidably installed in the frame along the length direction of the frame, the first positioning rod and the second positioning rod are parallel to each other, and two ends of the honeycomb curtain are respectively connected to the first positioning rod and the second positioning rod, and when the honeycomb curtain is unfolded, the honeycomb curtain shields the inner frame of the frame, and two groups of roller groups are arranged in the frame, each group of roller groups has two rollers, and the two rollers are connected by a pull rope transmission, the pull rope of one roller group is connected to the first positioning rod, and the pull rope of the other roller group is connected to the second positioning rod, and a driving mechanism is arranged in the frame, and the driving mechanism is used to drive the two groups of roller groups to move, and a resistance member for stopping the rollers from rotating is arranged on the frame.

[0008] By adopting the above technical solution, the positions of the two ends of the honeycomb curtain are adjusted by the first positioning rod and the second positioning rod, so that any position of the frame in the vertical direction along its installation direction can be shielded by adjusting the first positioning rod and the second positioning rod, thereby meeting the buyer's requirements for shielding specified positions and areas.

[0009] Optionally, the driving mechanism includes a driving motor, which is installed on the frame, a connecting rod is horizontally slidably installed in the frame, and the connecting rod is rotatably installed on the frame, the driving motor is transmission-connected to the connecting rod, the connecting rod is coaxial with two opposite rollers located on both sides of the frame, and two rollers in the two roller groups that are coaxial with the connecting rod are provided with connecting pieces for connecting to the connecting rod, the connecting rod can slide to one end thereof and connect to one of the connecting pieces, and at this time the other end of the connecting rod is separated from the other connecting piece, and the frame is also provided with a driving piece for driving the connecting rod to move.

[0010] By adopting the above technical solution, when the driving motor is started, if the driving motor is running in the forward direction, the driving member drives the connecting rod to be connected to the roller transmission of the roller group used to drive the first positioning rod to slide. At this time, the driving motor is used to drive the first positioning rod to slide, and then to drive the upper end of the honeycomb curtain to move. Conversely, it is used to drive the second positioning rod to slide, and then to drive the lower end of the honeycomb curtain to move.

[0011] Optionally, the driving member includes a first magnet installed at both ends of the connecting rod, and an electromagnet is installed on the frame at the two rollers, and the connecting rod is driven to slide through the cooperation between the electromagnet and the first magnet.

[0012] By adopting the above technical solution, the connecting rod is driven to slide by the cooperation between the electromagnet and the first magnet. The installation space required for the driving part is small and the response is more timely. Compared with the drive achieved through mechanical transmission, the operating experience is improved.

[0013] Optionally, the connecting member includes a connecting tube coaxially installed on an end face of the roller facing the connecting rod, the inner hole of the connecting tube is a regular polygon, and a regular polygonal mounting tube slidably matched with the inner hole of the connecting tube is coaxially arranged on both ends of the connecting rod, the two first magnets are respectively installed in the two mounting tubes, and a chamfer is provided on the inner edge of the port of the connecting tube away from the roller, and a chamfer is also provided on the outer edge of the end face of the mounting tube away from the connecting rod.

[0014] By adopting the above technical solution, after the installation cylinder slides and is inserted into the connecting cylinder under the mutual cooperation between the first magnet and the electromagnet, the transmission connection between the roller and the connecting rod can be realized, and due to the relatively simple structure, it is not easy to get stuck.

[0015] Optionally, a sleeve is rotatably installed in the frame, the connecting rod is slidably installed in the sleeve, the connecting rod is installed on the frame through the sleeve, and the sleeve is transmission-connected to the drive motor through a gear.

[0016] By adopting the above technical solution, the connecting rod is connected to the driving motor through the sleeve, the connecting rod slides, and the sleeve rotates, so that the rotation and sliding actions are independent of each other, and thus the gears of the gear set used for transmission connection sleeve and driving motor will not have relative slippage due to the sliding of the connecting rod, and the gears of the gear set will not have additional wear due to relative sliding, thereby extending the service life of the gears and reducing noise during use.

[0017] Optionally, a limiting groove is provided on the inner wall of the sleeve, and the length direction of the limiting groove is arranged along the axis of the sleeve. A limiting block is arranged on the side wall of the connecting rod, and the limiting block is located in the limiting groove. Along the axial direction of the sleeve, the width of the limiting groove is greater than the width of the limiting block, and the connecting rod is rotatably matched with the sleeve.

[0018] By adopting the above technical scheme, the sleeve and the connecting rod are fixed in the circumferential direction and slide in the axial direction through the cooperation between the limit groove and the limit block. At the same time, since the width of the limit groove is greater than the width of the limit block, the connecting rod and the sleeve can be rotated relative to each other to a limited extent. Under the action of the electromagnet and the first magnet, when the mounting tube is slidably installed in the connecting tube, it can be adaptively rotated, so that the mounting tube can be inserted into the connecting tube more smoothly, and at the same time, the impact force when the mounting tube is inserted into the connecting tube is reduced, thereby making the first magnet in the mounting tube less prone to damage.

[0019] Optionally, the limit groove passes through the side wall of the sleeve, and the limit block is detachably mounted on the connecting rod. When one end of the mounting tube is slidably inserted into the connecting tube and there is a gap between the insertion end surface of the mounting tube and the bottom of the connecting tube, the limit block presses against one end of the limit groove in the length direction.

[0020] By adopting the above technical solution, the sliding stroke of the connecting rod is limited by the cooperation between the limit block and the limit groove. Since there is no contact between the bottom of the connecting cylinder and the end face of the mounting cylinder, no collision will occur and vibration will not be generated. Therefore, the first magnet in the mounting cylinder will not be broken due to vibration. At the same time, since there is no collision, there is no need to install an anti-collision layer on the end face of the mounting cylinder, so that there are fewer obstacles between the first magnet and the electromagnet and the magnetic force between the two is stronger.

[0021] Optionally, shock-absorbing layers are provided on both side walls of the limiting block along the length direction of the limiting groove.

[0022] By adopting the above technical solution, the shock-absorbing layer is used to protect the limit block and the limit groove, so that the limit block and the limit groove are not easily damaged due to frequent impacts.

[0023] Optionally, a wire groove is provided on the side wall of the roller, the pull rope is embedded in the wire groove, and the side wall of the pull rope is in close contact with the groove wall of the wire groove, the resistance member includes a spring installed on the frame, a second magnet is arranged on the spring, one end of the spring is connected to the frame, and the other end of the spring faces an end surface of the roller provided with the electromagnet, and the spring and the connecting rod are respectively located on both sides of the roller, and a damping block is arranged on the end of the spring facing the roller, the spring pushes the damping block to fit in close contact with an end surface of the roller away from the connecting rod to stop the roller from rotating, and when the electromagnet of the roller is activated, the electromagnet pushes the second magnet away from the roller, thereby separating the damping block from the roller.

[0024] By adopting the above technical solution, when the electromagnet at the roller is working, it will push the second magnet to compress the spring, so that the damping block is separated from the roller, and the roller can rotate freely. When the electromagnet loses power and stops working, under the action of the spring, the damping block will fit tightly against the roller to stop the roller from rotating. Since the damping block is pressed against or separated from the roller by the electromagnet, and the connection between the roller and the connecting rod is also controlled by the same electromagnet, the damping block can stop the roller from rotating in a timely manner and is less prone to errors. At the same time, when there is a power outage, since the damping block is used to stop the roller from rotating, the honeycomb curtain can also be manually pulled forcibly to block the light.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The positions of both ends of the honeycomb curtain are adjusted by the first positioning rod and the second positioning rod, so that any position of the frame in the vertical direction of its installation direction can be shielded by adjusting the first positioning rod and the second positioning rod, which can meet the buyer's requirements for shielding the designated position and area;

[0027] 2. The sliding drive of the connecting rod is performed by the mutual cooperation between the electromagnet and the first magnet. The installation space required for the driving part is small and the response is more timely. Compared with the drive realized by mechanical transmission, the operation experience is improved. The connecting rod is connected to the driving motor through the sleeve. The connecting rod slides and the sleeve rotates, so that the rotation and sliding actions are independent of each other, so that the gears of the gear set used for the transmission connection sleeve and the driving motor will not slide relative to each other due to the sliding of the connecting rod, so that the gears of the gear set will not have additional wear due to the relative sliding, thereby extending the service life of the gears and reducing the noise during use;

[0028] 3. The sleeve and the connecting rod are fixed in the circumferential direction and slide in the axial direction through the cooperation between the limit groove and the limit block. At the same time, since the width of the limit groove is greater than the width of the limit block, the connecting rod and the sleeve can be rotated relative to each other to a limited extent. Under the action of the electromagnet and the first magnet, when the mounting tube is slidably installed in the connecting tube, it can be adaptively rotated, so that the mounting tube can be inserted into the connecting tube more smoothly, and at the same time, the impact force when the mounting tube is inserted into the connecting tube is reduced, thereby making the first magnet in the mounting tube less prone to damage.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0035] Reference Figure 1 and Figure 2 Two roller groups 5 are arranged on the frame 1, each roller group 5 includes two rollers 51, a wire groove 52 in the form of an annular groove is opened in the middle of the side wall of the roller 51, and the cross section of the wire groove 52 is fan-shaped. The two rollers 51 are connected by a pull rope 6, and the pull rope 6 is embedded in the wire groove 52. A resistance member 8 is also arranged on the frame 1 to stop the roller 51 from rotating.

[0036] Reference Figure 1 and Figure 2 The pull rope 6 of one group of roller groups 5 passes through the first positioning rod 3 and is fixedly connected to the first positioning rod 3, and the pull rope 6 of the remaining group of roller groups 5 passes through the second positioning rod 4 and is fixedly connected to the second positioning rod 4. The rotation of the rollers 51 of the two roller groups 5 drives the two pull ropes 6 to move, thereby driving the sliding of the first positioning rod 3 and the sliding of the second positioning rod 4, and finally driving the honeycomb curtain 2 to freely cover the inner frame of the frame body 1.

[0037] Reference Figure 1 and Figure 2 A driving mechanism 7 is provided on the frame 1 for driving the two groups of roller groups 5 to move. The driving mechanism 7 includes a driving motor 71, a cylindrical connecting rod 72 and a sleeve 73. The sleeve 73 is horizontally rotatably mounted on the upper end of the frame 1, and the two ends of the sleeve 73 are respectively coaxial with the two rollers 51 on both sides of the frame 1, and the connecting rod 72 is slidably mounted in the sleeve 73.

[0038] Reference Figure 1 and Figure 2A limiting groove 731 is provided on the side wall of the sleeve 73, and the length direction of the limiting groove 731 is parallel to the axis of the sleeve 73. A cylindrical limiting block 721 is threadedly installed on the side wall of the connecting rod 72, and the diameter of the limiting block 721 is smaller than the width of the limiting groove 731. Through the cooperation of the limiting block 721 and the limiting groove 731, the connecting rod 72 can be driven to rotate when the sleeve 73 rotates. A gear 74 is coaxially fixedly installed on the side wall of the sleeve 73, and the driving motor 71 is fixedly installed on the frame 1, and a gear 74 is coaxially fixedly installed on the output shaft of the driving motor 71, and the two gears 74 are meshed with each other. The driving motor 71 drives the gear 74 to rotate, thereby driving the gear 74 on the sleeve 73 and the sleeve 73 to rotate, thereby driving the connecting rod 72 to rotate.

[0039] Reference Figure 1 and Figure 2 The driving mechanism 7 also includes two connecting members 9, which include a connecting tube 91 coaxially fixedly installed on one end face of the roller 51 facing the connecting rod 72, the inner hole of the connecting tube 91 is a regular octagon, and two mounting tubes 92 with regular octagonal cross sections are coaxially fixedly installed on both ends of the connecting rod 72. The sliding connecting rod 72 can slide one of the mounting tubes 92 on it into the mounting tube 92 to complete the connection between the connecting rod 72 and the roller 51.

[0040] Reference Figure 1 and Figure 2 A driving member 10 for driving the connecting rod 72 to move is provided on the frame 1. The driving member 10 includes an electromagnet 102 fixedly mounted on the frame 1 on the side of the roller 51 away from the connecting cylinder 91. A first magnet 101 is fixedly mounted in the mounting cylinder 92. When the electromagnet 102 is started, the first magnet 101 is attracted to the electromagnet 102, thereby driving the connecting rod 72 to slide to the mounting cylinder 92 and slide into the connecting cylinder 91.

[0041] Reference Figure 1 and Figure 2 When the connection tube 91 slides to the point where the distance between the bottom of the connection tube 91 and the end face of the installation tube 92 facing away from the connection rod 72 is a gap, the limit block 721 presses against one end of the limit groove 731, and the collision between the limit block 721 and the end face of the limit groove 731 replaces the collision between the connection tube 91 and the installation tube 92, so that the first magnet 101 in the installation tube 92 is not easily damaged by the vibration caused by the collision. A rubber shock-absorbing layer 722 is fixedly installed on the two opposite side walls of the limit block 721 along the length direction of the limit groove 731 for buffering, further reducing vibration.

[0042] Reference Figure 1 and Figure 2, two resistance members 8 are provided to respectively stop the rollers 51 of the two roller groups 5 from rotating. Two mounting tubes are integrally provided on the frame 1, and the two mounting tubes are respectively provided with two electromagnets 102 fixedly installed in the two mounting tubes, and two springs 81 are respectively sleeved on the two mounting tubes. One end of the spring 81 is fixedly connected to the frame 1, and a ring-shaped damping block 83 is fixedly installed on the other end of the spring 81. Under the elastic force of the spring 81, the damping block 83 is pressed against the end face of the roller 51 away from the connecting rod 72 to stop the roller 51 from rotating.

[0043] Reference Figure 1 and Figure 2 A second magnet 82 is also fixedly mounted on the spring 81. The magnetic poles of the second magnet 82 are the same as the magnetic poles of the first magnet 101 on the same side. When the electromagnet 102 is started, the electromagnet 102 exerts a repulsive force on the second magnet 82, thereby pushing the spring 81 to compress and separate the damping block 83 from the roller 51, so as to drive the motor 71 to drive the roller 51 to rotate.

[0044] The implementation principle of an electric honeycomb blind with adjustable shielding position in the embodiment of the present application is:

[0045] When the upper end of the honeycomb curtain 2 needs to be lowered, the electromagnet 102 at the roller 51 connected to the first positioning rod 3 is started, and the connecting rod 72 is attracted to be connected to the roller 51 through the connecting tube 91 and the mounting tube 92. At this time, under the magnetic force of the electromagnet 102, the second magnet 82 drives the spring 81 to be compressed, so that the damping block 83 is separated from the roller 51. At this time, the driving motor 71 is started to drive the roller 51 to rotate, and then the upper end of the honeycomb curtain 2 is driven to descend or rise through the sliding of the first positioning rod 3. When the upper end of the honeycomb curtain 2 is at the target position, the driving motor 71 stops, the electromagnet 102 stops, and the spring 81 pushes the damping block 83 to press against the roller 51 to stop the roller 51 from rotating.

[0046] When the lower end position of the honeycomb curtain 2 needs to be adjusted, the other end of the connecting rod 72 is connected to another roller 51 , and the above process is repeated to adjust the lower end position of the honeycomb curtain 2 .

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
