[0022] The best embodiment of this utility model

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Referring to Figures 1, 2 and 3, a hand-flash integrated roller blind of this embodiment includes a bracket 1, a roller blind assembly 2 is provided on the bracket 1, the roller blind assembly 2 includes a roller 21 and a curtain 22, one end of the curtain 22 is connected to the roller 21, and the other end of the curtain 22 is connected to a tail plate 23.

[0025] The drum 21 is equipped with a power mechanism, which includes a spiral spring energy storage component 3, a tubular motor 4, and a mechanical clutch assembly 5. The tubular motor 4 is connected to the drum 21 through the mechanical clutch assembly 5. The output end of the mechanical clutch assembly 5 is connected to the drum 21 through a rotating wheel. The output end of the mechanical clutch assembly 5 is fixedly connected to the rotating wheel. The rotating wheel is engaged with the drum 21. The spiral spring energy storage component 3 is connected to the drum 21 through a drive mechanism.

[0026] Among them, the outer rotating frame on the spiral spring energy storage component 3 is fixedly connected to the drum 21. When the drum 21 rotates, the torque of the spiral spring energy storage component 3 can be stored or released simultaneously, so that the curtain 22 can stop at any position.

[0027] Among them, the torque of the spiral spring energy storage component 3 located in the roller blind assembly 2 can be balanced by the combined gravity of the curtain 22 and the tail plate 23.

[0028] The mechanical clutch assembly 5 allows the curtain 22 to descend or rise when the user manually pulls down or pushes up the tail plate 23. At the same time, the drum 21 will rotate, and under the action of the spiral spring energy storage component 3, it can stop at any position. During the rotation of the drum 21, the mechanical clutch assembly 5 will be activated and disengaged, so that the output shaft of the motor will not rotate, thereby protecting the motor.

[0029] When the motor rotates, the mechanical clutch assembly 5 engages, thereby transmitting the output power to the drum 21, thus realizing the electric control of the raising and lowering of the curtain 22.

[0030] The mechanical clutch assembly 5 is either built into or external to the tubular motor 4. The mechanical clutch assembly 5 can be installed inside the tubular motor 4, thus forming an integral part with the tubular motor 4.

[0031] The mechanical clutch assembly 5 can be installed outside the tubular motor 4. Preferably, the mechanical clutch assembly 5 can be installed in conjunction with the rotary wheel to reduce the space occupied by the mechanical clutch assembly 5.

[0032] Referring to Figures 3 and 4, the mechanical clutch assembly 5 includes an output component 51 and a clutch part 52, and the tubular motor 4 includes a motor assembly, which includes a motor. Generally, a reducer can be connected to the output end of the motor, and the output end of the reducer is the output end of the motor assembly.

[0033] The output component 51 is connected to the drive drum 21. The clutch part 52 is provided at the output end of the output component 51 and the motor assembly. The clutch part 52 is used to realize the engagement and disengagement between the output component 51 and the output end of the motor assembly.

[0034] Compared with electromagnetic clutch, mechanical clutch assembly 5 does not require the design of a control board, thus reducing the use of a control board.

[0035] Referring to Figures 4 and 5, the clutch part 52 includes an iron part 521, a clutch part 522, and a magnetic bead 523. The magnetic bead 523 is attracted to the iron part 521 and is located on opposite sides of the clutch part 522. The clutch part 522 is fixedly connected to the output end of the motor assembly. Two grooves 511 that cooperate with the magnetic bead 523 are provided in the output part 51. The iron part 521 is fixedly connected to the tubular motor 4, and the output end of the motor assembly passes through the iron part 521.

[0036] When the tubular motor 4 is working, the motor assembly will drive the clutch 522 to rotate simultaneously. The rotation of the clutch 522 will push the magnetic bead 523 to move toward the corresponding groove 511, so that the magnetic bead 523 is engaged between the corresponding groove 511 and the clutch 522, thereby driving the output part 51 to rotate, causing the drum 21 to rotate.

[0037] When the user manually pulls the curtain 22, the roller 21 will rotate. At this time, under the action of the wheel, the torque of the spiral spring energy storage component 3 can be stored or released simultaneously, the output component 51 will rotate, the magnetic bead 523, the clutch component 522 and the groove 511 will be in a disengaged state, the magnetic bead 523 will be attracted to the iron part 521 due to the attraction force, so it will not affect the motor, thus protecting the motor.

[0038] Referring to Figure 3, the iron part 521 is fixedly connected to the end cap 41 of the tubular motor 4, the motor assembly, or the outer tube 43 of the tubular motor 4.

[0039] When the iron part 521 is fixedly connected to the end cover 41 of the tubular motor 4, the mechanical clutch assembly 5 is placed outside the tubular motor 4, the end cover 41 of the tubular motor 4 is fixedly connected to the outer tube 43, and the iron part 521 can be fixedly connected to the end face of the end cover 41.

[0040] When the iron part 521 is fixedly connected to the outer tube 43 of the motor assembly or the tubular motor 4, the mechanical clutch assembly 5 is built into the tubular motor 4.

[0041] Among them, the end of the reducer on the motor assembly is fixedly connected to the iron part 521, and the output end of the reducer passes through the iron part 521 without interfering with the iron part 521.

[0042] When the iron piece 521 is fixedly connected to the outer tube 43 of the tubular motor 4, the iron piece 521 is located inside the outer tube 43 of the tubular motor 4, and a fixed connection is formed between it and the inner wall of the outer tube 43.

[0043] A first bearing 42 is connected between the output component 51 and the end cover 41 of the tubular motor 4, which can increase the coaxiality between the output component 51 and the output end of the motor assembly. In this scheme, the mechanical clutch assembly 5 is built into the tubular motor 4.

[0044] The clutch part 52 also includes an input part 53, and the iron part 521 is fixedly connected to the input part 53. The input part 53 is fixedly connected to the end cover 41 of the tubular motor 4, the outer tube 43 of the tubular motor 4, or the motor assembly.

[0045] When the input component 53 is installed on the motor assembly, the input component 53 can be installed on the housing of the reducer, and the iron part 521 can be fixedly connected to the input component 53, which can avoid the situation of insufficient space on the housing of the reducer.

[0046] A gap is formed between the input component 53 and the clutch component 522. One end of the iron component 521 is inserted into the gap and is circumferentially limited between it and the input component 53. The iron component 521 includes an extension section that extends into the gap, thereby positioning the iron component 521 and facilitating its installation.

[0047] The side of the extension of the iron part 521 is provided with at least one first plane, and the input part 53 is provided with a second plane that cooperates with the first plane, thereby restricting the circumferential rotation of the iron part 521. The iron part 521 will not rotate with the rotation of the output end of the tubular motor 4.

[0048] The input component 53 can also be set on the end cover 41 of the tubular motor 4. The iron part 521 is fixedly connected to the input component 53. When the mechanical clutch assembly 5 is external, the insufficient space on the end cover 41 of the tubular motor 4 can be avoided.

[0049] The input component 53 can also be set on the outer tube 43 of the tubular motor 4. In this case, the input component 53 is located inside the outer tube 43 of the tubular motor 4 and is fixedly connected to the inner wall of the outer tube 43.

[0050] The output component 51 and the input component 53 are rotatably connected, wherein a second bearing can be connected between the output component 51 and the input component 53, so that the central axis of the output component 51 can coincide with the central axis of the input component 53.

[0051] Referring to Figure 3, the tubular motor 4 has a built-in lithium battery 44 or an external power cord. Preferably, the tubular motor 4 has an external power cord. Since the tubular motor 4 in the roller blind assembly 2 does not lift or lower, its height position is fixed, and the power cord can provide power for a long time.

[0052] A lithium battery 44 can also be used to adapt to installation locations without a socket.

[0053] The bracket 1 has a receiving cavity for accommodating the roller blind assembly 2. When the curtain 22 is rolled up, the roller blind assembly 2 can be hidden in the receiving cavity and cannot be observed by the user from the outside, which is aesthetically pleasing. In addition, the tail plate 23 can be exposed on the bracket 1, and the user can see the position of the tail plate 23 directly and then manually pull the tail plate 23.

[0054] Of course, depending on the needs, the tailgate 23 can also be designed to be hidden.

[0055] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
