Referring to fig. 1, a blind dimmer in one embodiment is used to control a control rod 10 of a blind. Referring to fig. 2, the blind dimmer includes a housing 100, a clamping mechanism 200, a driving mechanism 300, and a mounting mechanism 400, wherein the mounting mechanism 400 includes a mounting base 410 and a connecting member 420, the connecting member 420 is connected between the mounting base 410 and the housing 100, and the housing 100 is disposed on a mounting surface through the mounting base 410. The clamping mechanism 200 is clamped on the operating rod 10 and is rotatably arranged in the shell 100, and the driving mechanism 300 is in transmission connection with the clamping mechanism 200; the driving mechanism 300 is used to drive the clamping mechanism 200 to rotate and drive the operating rod 10 to rotate.

Referring to fig. 1 and 2, the window blind includes a curtain rod 20 and a plurality of vanes (not shown) mounted to the curtain rod 20. The driving mechanism 300 drives the clamping mechanism 200 to rotate, and drives the operating rod 10 to rotate so as to open and close the plurality of blades, thereby opening and closing the blind.

In the shutter dimmer, the housing 100 is arranged on the mounting surface through the mounting mechanism 400, so that the mounting and dismounting are convenient; the clamping mechanism 200 is clamped on the operating rod 10, so that the operating rod 10 on the blind window can be conveniently driven to rotate, and the opening and closing of the blades of the blind window can be well controlled.

Here, the installation surface may be a curtain rod 20 of a blind, a wall or a window wall, or the like. One end of the mounting mechanism 400 is mounted on the mounting surface, and the other end of the mounting mechanism 400 is connected to the housing 100 of the blind dimmer. In this way, the housing 100 of the blind dimmer is attached to the blind rod 20 of the blind via the attachment mechanism 400, and the clamping mechanism 200 of the blind dimmer is clamped to the operating rod 10, thereby achieving the attachment of the blind dimmer without interfering with the rotation of the operating rod 10.

In this embodiment, the mounting mechanism 400 and the housing 100 are a separate structure and are detachably connected. In other embodiments, the mounting mechanism 400 and the housing 100 can be integrally formed, and have good integrity and high mechanical strength.

In this embodiment, the mounting base 410 is fixed to the mounting surface by screws or bolts or glue. In other embodiments, the mounting 410 may be hung on the curtain rod 20 of the blind or otherwise support the entire housing 100.

Referring to fig. 1 and 2, the housing 100 includes a first housing 110 and a second housing 120 connected to each other, the second housing 120 includes a main body 121 and an opening/closing portion 122, the opening/closing portion 122 is connected to the main body 121 and forms a cavity 120a, and the main body 121 is connected to the first housing 110. The clamping mechanism 200 is rotatably disposed in the receiving cavity 120a, and the driving mechanism 300 is disposed inside the first housing 110.

Thus, the open-close portion 122 and the body 121 are separated or rotated relatively to open the cavity 120a, so as to be adapted to different clamping mechanisms 200. Different clamping mechanisms 200 are used to adapt to different specifications of operating rods 10, facilitating the adaptation of the blind dimmer to various specifications of blinds.

Here, the first casing 110 and the second casing 120 may be an integrally formed structure, that is, the first casing 110 and the second casing 120 are different parts of the same outer shell 100. Alternatively, the first housing 110 and the second housing 120 may be a split structure, that is, the first housing 110 and the second housing 120 are separately processed components.

Further, the clamping mechanism 200 is removably mounted within the housing 120a, thus facilitating quick replacement or maintenance of the clamping mechanism 200 within the housing 120a by a user.

In this embodiment, the body 121 and the first housing 110 are integrally formed, and have good integrity and high mechanical strength. In other embodiments, the body 121 and the first housing 110 may also be a split structure.

According to some embodiments of the present application, the body 121 and the opening/closing portion 122 are of a split structure and are rotatably connected.

Specifically, in an embodiment, referring to fig. 2 and fig. 3, one end of the opening/closing portion 122 is pivotally connected to one end of the main body 121, and the other end of the opening/closing portion 122 is locked to the other end of the main body 121 by a locking member, where the locking member includes a first locking portion 131 disposed on the opening/closing portion 122 and a second locking portion 132 disposed on the main body 121. When the first locking portion 131 and the second locking portion 132 are in the locked state, the body 121 and the opening/closing portion 122 are locked with each other; when the first locking portion 131 and the second locking portion 132 are in the unlocked state, the opening/closing portion 122 can rotate relative to the body 121 to open the cavity 120a. Thus, the first locking portion 131 and the second locking portion 132 are matched with each other, so that the cavity 120a can be switched between the open state and the closed state, and the operation is convenient.

In this embodiment, referring to fig. 3 and 5, one of the opening/closing portion 122 and the main body 121 is provided with a rotating shaft, the other of the opening/closing portion 122 and the main body 121 is provided with a rotating hole 122a, and the rotating shaft is rotatably provided in the rotating hole 122a, so that one end of the opening/closing portion 122 is pivotally connected to one end of the main body 121. In other embodiments, the opening/closing portion 122 and the body 121 may be pivoted by a ball hinge or a hinge.

Further, referring to fig. 3, the second housing 120 further includes a locking plate 123 having a second locking portion 132, and the locking plate 123 is movably disposed on the body 121 to make the first locking portion 131 and the second locking portion 132 dislocate during the locking process or the unlocking process.

Thus, the first locking portion 131 and the second locking portion 132 are dislocated in the locking process or the unlocking process, which is convenient for the locking or unlocking of the first locking portion 131 and the second locking portion 132; or the second housing 120 further includes a locking piece 123 having a first locking portion 131, and the locking piece 123 is movably disposed on the opening/closing portion 122 to be dislocated during the locking process or the unlocking process of the first locking portion 131 and the second locking portion 132.

In this embodiment, the movable direction of the locking plate 123 is perpendicular to the opening direction of the opening and closing part 122, for example, the locking plate 123 can move up and down, and then the opening and closing part 122 can be opened along the left and right directions, so that the dislocation direction is more reasonable, and the opening and closing control is smoother.

For example, when the second housing 120 includes the locking piece 123 having the second locking portion 132, the locking piece 123 is movably disposed on the body 121, and the first locking portion 131 is disposed on the opening/closing portion 122. When the first locking portion 131 and the second locking portion 132 are switched from the locked state to the unlocked state, moving the locking plate 123 upward relative to the body 121 will drive the second locking portion 132 to move upward, and at this time, the second locking portion 132 can be disengaged from the first locking portion 131. Moving the locking plate 123 downward will drive the second locking portion 132 to move downward, at this time, the second locking portion 132 can be engaged with the first locking portion 131, and the first locking portion 131 and the second locking portion 132 are switched from the unlocked state to the locked state again.

Optionally, both the first locking portion 131 and the second locking portion 132 are provided with a snap. When the locking device is in a locking state, the two buckles are in a buckling state; when in the unblock state, two buckles are in the disconnect-type state.

In the present embodiment, the number of the snaps is not limited to two, and when the first locking portion is at least two in number or the second locking portion 132 is at least two in number, the snaps can be arranged side by side at an interval in the vertical direction. Here, the number of the snaps is not particularly limited.

In this embodiment, the two buckles are both in a hook shape for being engaged with each other, and in other embodiments, the buckles may also be in other shapes, which is not limited herein.

Optionally, one of the first locking portion 131 and the second locking portion 132 is a locking slot, and the other of the first locking portion 131 and the second locking portion 132 is a buckle. When the locking device is in a locking state, the buckle is clamped in the clamping groove; when in the unlocking state, the buckle is separated from the clamping groove.

In this embodiment, the quantity of buckle and draw-in groove is all not limited to one, and when the quantity of buckle and draw-in groove was at least two, each buckle and draw-in groove can be followed vertical direction interval and set up side by side. Here, the number of the engaging pieces and the engaging grooves is not particularly limited.

In this embodiment, the buckle is the rectangle piece, and the draw-in groove also is the rectangle in order with the buckle adaptation. Correspondingly, the buckle can also be in a round block shape or other shapes, and the clamping groove can also be in a round shape or other shapes. Here, the shapes of the clip and the clip groove are not particularly limited.

In this embodiment, the locking piece 123 may have a long bar shape, a round shape, or other shapes. Here, the shape of the locking piece 123 is not particularly limited.

Further, referring to fig. 3, an elastic member 124 is disposed between the locking piece 123 and the body 121 or between the locking piece 123 and the opening/closing portion 122, and the elastic member 124 is used for resetting the locking piece 123 after the second locking portion 132 and the first locking portion 131 are locked and/or unlocked.

For example, when the second housing 120 includes the locking piece 123 having the second locking portion 132, the locking piece 123 is movably disposed on the body 121, the first locking portion 131 is disposed on the opening/closing portion 122, and the elastic member 124 is disposed between the locking piece 123 and the body 121 for restoring the locking piece 123.

Optionally, the elastic member 124 is a spring.

For example, in one embodiment, the elastic member 124 is a compression spring, and when the first locking portion 131 and the second locking portion 132 are in the locked state, the elastic member 124 is in a slightly compressed state or a normal state; when the first locking portion 131 and the second locking portion 132 are switched from the locked state to the unlocked state (for example, when the second housing 120 needs to be opened), the locking plate 123 is moved upward relative to the body 121 by a hand, the second locking portion 132 is driven to move upward, the second locking portion 132 can be separated from the first locking portion 131, the elastic member 124 is further compressed, and after the hand is released, the locking plate 123 is automatically reset by the restoring force of the elastic member 124, so that the need of manual reset or loosening is avoided.

For another example, in another embodiment, the elastic member 124 is a tension spring, when the first locking portion 131 and the second locking portion 132 are in the locked state, the elastic member 124 is in a slightly stretched state or a normal state, when the locking piece 123 is moved up relative to the body 121 by a hand, the elastic member 124 is stretched, and after the hand is released, the locking piece 123 is automatically reset by the restoring force of the elastic member 124.

Further, referring to fig. 3 and fig. 6, the first locking portion 131 or the second locking portion 132 is provided with a guiding surface 125, and the first locking portion 131 and the second locking portion 132 are locked by the guiding surface 125.

In this embodiment, the guiding surface 125 is an inclined surface, which can play a guiding role during the locking or unlocking process of the first locking portion 131 and the second locking portion 132, so as to facilitate quick locking or unlocking.

Specifically, in another embodiment, referring to fig. 1, the opening/closing portion 122 is covered on the body 121, and the opening/closing portion 122 is covered on or separated from the body 121 to open or close the cavity 120a. Thus, when the opening-closing portion 122 covers the body 121, the cavity 120a is in a closed state; when the opening and closing part 122 is detached from the body 121, the receiving cavity 120a is in an open state.

In this embodiment, when the opening/closing portion 122 covers the body 121, the opening/closing portion 122 and the body 121 are in interference fit to close the cavity 120a.

Specifically, referring to fig. 3 and 7, the clamping mechanism 200 includes at least two clamping portions 210 installed in the cavity 120a, and all the clamping portions 210 clamp the operating rod 10 together.

Here, the shapes of all the clamping portions 210 may or may not be completely the same. For example, all of the clamping portions 210 may have at least one of an elongated shape, a semi-cylindrical shape, or a wavy shape. Here, the shape of the clamping portion 210 is not particularly limited.

Referring to fig. 7, at least one clamping portion 210 can move or rotate to disengage the operating rod 10 from the clamping mechanism 200. In this way, the clamping mechanism 200 can be adapted to different operating levers 10 and is easy to quickly disassemble and assemble.

When one clamping portion 210 is rotatable, the clamping portion 210 has a rotating shaft, and the other clamping portion 210 has a rotating slot, the rotating shaft is rotatably disposed in the rotating slot and detachably connected to the rotating slot, so that one end of one clamping portion 210 is rotatably connected to one end of the other clamping portion 210, and the clamping portion 210 is convenient to assemble.

Here, the at least one clamping portion 210 may be movable or rotatable, which may be understood as that only one clamping portion 210 may be movable or rotatable, or that at least two clamping portions 210 may be movable or rotatable.

More specifically, referring to fig. 7, the clamping mechanism 200 has a clamping cavity 201 for clamping the operating rod 10 therein, and the clamping mechanism 200 further includes a bushing 220, wherein the bushing 220 is detachably disposed in the clamping cavity 201 and fixed to the outer circumference of the operating rod 10. The bushing 220 may be of unitary or split construction.

In this way, the operating rod 10 with different specifications (different diameters) can be matched by replacing the bushing 220 with different thicknesses, so that the clamping mechanism 200 does not need to be replaced, and the cost is saved. In other embodiments, which do not require the use of a bushing 220, the clamping mechanism 200 can be removably attached by direct replacement to accommodate an irregular operating rod.

Here, the bushing 220 may be detachably disposed in the clamping cavity 201 by a plug-in or snap-in manner. The material of the bushing 220 may be a plastic material to increase the friction between the bushing 220 and the operating rod 10, so as to prevent the operating rod 10 from being separated from the clamping cavity 201 during the rotation process.

Referring to fig. 8 and 9, the connecting member 420 is an integral or split structure with adjustable length, so that the distance between the housing 100 and the mounting seat 410 in the height direction is adjustable.

It is understood that when the blind dimmer is clamped at different height positions of the operating rod 10, the distance between the blind dimmer and the curtain rod 20 in the height direction is adjustable. By making the connection member 420 have an integral or separate structure with an adjustable length, the connection member 420 is adjustable in length in the height direction, so that the distance between the housing 100 and the mounting seat 410 in the height direction is adjustable.

For example, referring to fig. 9, the connecting member 420 is a split structure and includes a plurality of connecting rods 421 inserted into each other, a plurality of inserting holes are formed in the connecting rods 421 in the height direction, an inserting block of an adjacent connecting rod 421 is inserted into one of the inserting holes, and the length of the connecting rod 421 in the height direction is adjusted by adapting to the inserting holes with different heights.

Alternatively, the knob 434 and the rotating portion 433 may be separate structures, and the knob 434 may be detachably connected to the rotating portion 433.

Referring to fig. 3 and 4, the blind light modulator further includes a transmission mechanism 500 and a clutch mechanism 600, the transmission mechanism 500 is connected to the clamping mechanism 200 and the driving mechanism 300, and the clutch mechanism 600 is drivingly connected to or disconnected from the transmission mechanism 500.

Here, the clutch mechanism 600 is mounted inside the first case 110 of the housing 100.

Specifically, when the clutch mechanism 600 is in the engaged state, the output power of the driving mechanism 300 is transmitted to the transmission mechanism 500 through the clutch mechanism 600, and the transmission mechanism 500 drives the clamping mechanism 200 to rotate and drives the operating rod 10 to rotate; when the clutch mechanism 600 is in the disengaged state, the clutch mechanism 600 is disengaged from the transmission mechanism 500, and the operation lever 10 is manually rotated. Thus, the blind can be electrically opened and closed through the blind dimmer, and meanwhile, the blind can be manually opened and closed, so that the integrated design requirements of electric opening and closing and manual opening and closing of the blind are met.

For example, when the blind needs to be opened and closed electrically, the clutch mechanism 600 is in the engaged state, and the driving mechanism 300, the clutch mechanism 600 and the transmission mechanism 500 can drive the clamping mechanism 200 to rotate; when the shutter needs to be opened or closed manually, the clutch mechanism 600 may be in the disengaged state.

Referring to fig. 4, the transmission mechanism 500 includes a driving wheel 510 and a driven wheel 520 engaged with each other, the clutch mechanism 600 is disposed in the driving wheel 510, the driven wheel 520 is fixed to or integrally formed with the clamping mechanism 200, and the driving wheel 510 is connected to the driving mechanism 300.

In this embodiment, when the driven wheel 520 is integrally formed on the clamping mechanism 200, one end of the clamping mechanism 200 can be used as the driven wheel 510 to be engaged with the driving wheel 520, and in other embodiments, both ends of the clamping mechanism 200 can be used as the driven wheel 510 to be engaged with the driving wheel 520, so as to facilitate the installation of the clamping mechanism 200 in the cavity 120a of the second housing 120.

Under the driving of the driving mechanism 300, the driving wheel 510 rotates around the first direction or the second direction of the housing 100, and the driven wheel 520 rotates around the first direction of the housing 100, wherein the first direction is perpendicular to or oblique to the second direction.

Here, referring to fig. 3 and 4, when the driving wheel 510 and the driven wheel 520 rotate around the first direction, the driving wheel 510 and the driven wheel 520 are engaged laterally; referring to fig. 10, when the driving wheel 510 rotates in the second direction and the driven wheel 520 rotates in the first direction, the driving wheel 510 and the driven wheel 520 are engaged longitudinally.

It should be noted that the first direction is an axial direction of the operation rod 10, i.e., an X direction shown in fig. 3; the second direction is the Y direction shown in fig. 3.

Specifically, referring to fig. 3 and 10, the axis of the driving wheel 510 is perpendicular to or parallel to the axis of the driven wheel 520.

Referring to fig. 4, the clutch mechanism 600 includes an absorbing plate 610 and a movable block 620, the absorbing plate 610 is installed in the driving wheel 510, the movable block 620 is movably disposed in the driving wheel 510 and can magnetically absorb the absorbing plate 610, the driving mechanism 300 includes a driving element 310 and a swinging element 320 connected to each other, and a limiting groove 511 is formed in the driving wheel 510 along a radial direction thereof.

When the clutch mechanism 600 is in the engaged state, the driving member 310 drives the oscillating member 320 to rotate, and after the oscillating member 320 pushes the movable block 620 to move and clamp the limiting groove 511, the movable block 620 is continuously pushed to drive the driving wheel 510 to rotate, and the driven wheel 520 and the clamping mechanism 200 are driven to rotate, so as to drive the operating rod 10 to rotate; when the clutch mechanism 600 is in the disengaged state, the movable block 620 is disengaged from the stopper groove 511, and the operation lever 10 is manually rotated.

It can be understood that the driving mechanism 300 is used for driving the swinging member 320 to rotate, the swinging member 320 is used for pushing the movable block 620 when rotating, and pushing the movable block 620 into the limiting groove 511, and the limiting groove 511 is configured such that the movable block 620 can be separated from the limiting groove 511 when the swinging member 320 does not push the movable block 620 and the driving wheel 510 rotates under the external force. Specifically, the depth of the limiting groove 511 is smaller than the radial dimension of the movable block 620, the movable block 620 is cylindrical, and the groove wall of the limiting groove 511 is arc-shaped.

When the clutch mechanism 600 is in the engaged state, referring to fig. 4 and fig. 3, the driving mechanism 300 drives the swinging member 320 to rotate, the swinging member 320 pushes the movable block 620 to move, the pushing force of the swinging member 320 makes the movable block 620 overcome the adsorption force of the adsorption plate 610, and pushes the movable block 620 to be clamped in the limit groove 511, and then the swinging member 320 continues to push the movable block 620 to drive the driving wheel 510 to rotate, and drive the driven wheel 520 and the clamping mechanism 200 to rotate, thereby implementing the electric control of the window blind.

When the clutch mechanism 600 is in the disengaged state, please refer to fig. 3 and fig. 4, the operating rod 10 is manually rotated, at this time, the operating rod 10 rotates to drive the clamping mechanism 200 to rotate, the clamping mechanism 200 drives the driven wheel 520 and the driving wheel 510 to rotate, the movable block 620 is not pressed in the limiting groove 511 by the thrust of the swinging member 320, along with the continuous rotation of the driving wheel 510, the groove wall of the limiting groove 511 pushes the movable block 620, and the movable block 620 is subjected to the adsorption force of the adsorption plate 610, i.e., is subjected to the resistance of the adsorption plate 610, so, along with the movement of the driving wheel 510, the movable block 620 moves towards the notch and along the arc-shaped groove wall of the limiting groove 511. And because the depth of the limiting groove 511 is smaller than the radius of the movable block 620, at this time, the movable block 620 can be separated from the limiting groove 511 under the pushing of the limiting groove 511, and the rotation of the driving wheel 510 is not hindered by the blocking effect of the swinging piece 320 on the movable block 620, so that the manual operation can be realized.

Alternatively, the adsorption plate 610 is an iron sheet, and the movable block 620 is a magnet; alternatively, the adsorption plate 610 is a magnet and the movable block 620 is an iron block.
