It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] Reference Figure 1 , Figure 2 and Figure 3 As shown, a flashlight integrated roller blind of this embodiment includes a bracket 1, a roller blind assembly 2 is arranged on the bracket 1, and 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;

[0024] A power mechanism is arranged inside the reel 21, and the power mechanism includes a scroll spring energy storage member 3, a tubular motor 4 and a mechanical clutch assembly 5. The tubular motor 4 is connected to the reel 21 through the mechanical clutch assembly 5, and the output end of the mechanical clutch assembly 5 is connected to the reel 21 through a rotating wheel. The output end of the mechanical clutch assembly 5 is fixedly connected to the rotating wheel, and the rotating wheel is clamped to the reel 21. The scroll spring energy storage member 3 is connected to the reel 21 through a rotating wheel.

[0025] The outer rotating frame on the scroll spring energy storage member 3 is fixedly connected to the drum 21. When the drum 21 rotates, the torsion of the scroll spring energy storage member 3 can be stored or released at the same time, so that the curtain 22 can stop at any position.

[0026] The torsion of the spiral spring energy storage member 3 in the rolling curtain assembly 2 can achieve balance with the gravity of the curtain fabric 22 and the tail plate 23;

[0027] The arrangement of the mechanical clutch assembly 5 enables the curtain 22 to drop or rise when the user manually pulls down or pushes up the tail plate 23. At this time, the reel 21 rotates at the same time and can stop at any position under the action of the spiral spring energy storage member 3. During the rotation of the reel 21, the mechanical clutch assembly 5 works and disengages, so that the output shaft of the motor does not rotate, thereby protecting the motor.

[0028] When the motor rotates, the mechanical clutch assembly 5 will be engaged, thereby transmitting the output power to the winding drum 21, thereby realizing the electric control of the rise and fall of the curtain 22.

[0029] The mechanical clutch assembly 5 is built-in or external to the tubular motor 4. The mechanical clutch assembly 5 can be arranged inside the tubular motor 4, so as to form an integral body with the tubular motor 4.

[0030] The mechanical clutch assembly 5 may be arranged outside the tubular motor 4 , wherein preferably, the mechanical clutch assembly 5 may be arranged in cooperation with the rotating wheel, so as to reduce the space occupied by the mechanical clutch assembly 5 .

[0031] Reference Figure 3 and Figure 4 As shown, the mechanical clutch assembly 5 includes an output member 51 and a clutch portion 52, the tubular motor 4 includes a motor assembly, the motor assembly includes a motor, and 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;

[0032] The output member 51 is in transmission connection with the reel 21, and the clutch part 52 is provided between the output member 51 and the output end of the motor assembly, and the clutch part 52 is used to realize the clutch between the output member 51 and the output end of the motor assembly;

[0033] Compared with the electromagnetic clutch, the mechanical clutch assembly 5 does not need to design a control board, thereby reducing the use of control boards.

[0034] Reference Figure 4 and Figure 5 As shown, the clutch part 52 includes an iron piece 521, a clutch piece 522 and a magnetic bead 523. The magnetic bead 523 is adsorbed on the iron piece 521 and is located on two opposite sides of the clutch piece 522. The clutch piece 522 is fixedly connected to the output end of the motor assembly. Two grooves 511 cooperating with the magnetic bead 523 are provided in the output piece 51. The iron piece 521 is fixedly connected to the tubular motor 4, and the output end of the motor assembly passes through the iron piece 521.

[0035] When the tubular motor 4 is working, the motor assembly drives the clutch 522 to rotate at the same time. The rotation of the clutch 522 pushes the magnetic beads 523 to move toward the corresponding groove 511, so that the magnetic beads 523 are engaged between the corresponding groove 511 and the clutch 522, thereby driving the output member 51 to rotate, so that the reel 21 rotates;

[0036] When the user manually pulls the curtain 22, the reel 21 will rotate. At this time, under the action of the rotating wheel, the torsional energy of the spiral spring energy storage component 3 can store or release energy at the same time, the output component 51 will rotate, and the magnetic bead 523, the clutch component 522 and the groove 511 are in a disengaged state. The magnetic bead 523 will be adsorbed on the iron component 521 due to the adsorption force. Therefore, it will not affect the motor, thereby protecting the motor.

[0037] Reference Figure 3 As shown, the iron piece 521 is fixedly connected to the end cover 41 of the tubular motor 4 , the motor assembly or the outer tube 43 of the tubular motor 4 .

[0038] When the iron piece 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 piece 521 can be fixedly connected to the end surface of the end cover 41;

[0039] When the iron piece 521 is fixedly connected to the motor assembly or the outer tube 43 of the tubular motor 4, the mechanical clutch assembly 5 is built into the tubular motor 4;

[0040] The end of the reducer on the motor assembly is fixedly connected to the iron piece 521, and the output end of the reducer passes through the iron piece 521 without interfering with the iron piece 521;

[0041] 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 is fixed to the inner wall of the outer tube 43 .

[0042] A first bearing 42 is connected between the output member 51 and the end cover 41 of the tubular motor 4 , which can increase the coaxiality between the output member 51 and the output end of the motor assembly. In this solution, the mechanical clutch assembly 5 is built into the tubular motor 4 .

[0043] The clutch part 52 further includes an input member 53, the iron member 521 is fixedly connected to the input member 53, and the input member 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;

[0044] When the input member 53 is disposed on the motor assembly, the input member 53 can be disposed on the housing of the reducer, and the iron member 521 can be fixedly connected to the input member 53, thereby avoiding the situation where there is insufficient space on the housing of the reducer;

[0045] A gap is formed between the input member 53 and the clutch member 522. One end of the iron member 521 is inserted into the gap and is circumferentially limited between the input member 53. The iron member 521 includes an extension section, which extends into the gap, thereby positioning the iron member 521 and facilitating the installation of the iron member 521.

[0046] At least one first plane is formed on the side of the extension section of the iron piece 521 , and a second plane matching the first plane is formed at the input piece 53 , thereby limiting the circumferential rotation of the iron piece 521 , and the iron piece 521 will not rotate with the rotation of the output end of the tubular motor 4 .

[0047] The input member 53 may also be arranged on the end cover 41 of the tubular motor 4, and the iron member 521 is fixedly connected to the input member 53. When the mechanical clutch assembly 5 is externally arranged, the situation of insufficient space on the end cover 41 of the tubular motor 4 can be avoided;

[0048] The input member 53 may also be disposed on the outer tube 43 of the tubular motor 4 . In this case, the input member 53 is located inside the outer tube 43 of the tubular motor 4 and is fixedly connected between the inner walls of the outer tube 43 .

[0049] The output member 51 is rotationally connected to the input member 53 , wherein a second bearing may be connected between the output member 51 and the input member 53 , so that the central axis of the output member 51 can coincide with the central axis of the input member 53 .

[0050] Reference Figure 3 As shown, the tubular motor 4 has a built-in lithium battery 44 or an external power cord. Preferably, the tubular motor 4 is externally connected to the power cord. Since the tubular motor 4 in the roller shutter assembly 2 does not move up or down, its height position is constant, and the power cord can provide long-term power supply.

[0051] A lithium battery 44 may also be used to fit an installation location that does not have a socket.

[0052] A receiving cavity is formed in the bracket 1, and the receiving cavity is used to receive the rolling shutter assembly 2. When the curtain 22 is retracted, the rolling shutter assembly 2 can be hidden in the receiving cavity, and the user cannot observe it from the outside, which has a good appearance. In addition, the tail plate 23 can be exposed from the bracket 1, and the user can intuitively see the position of the tail plate 23, so as to manually pull the tail plate 23.

[0053] Of course, as required, the tail plate 23 can be designed to be hidden.
