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.

[0026] Reference Figure 1 , Figure 2 and Figure 3As shown, a flashlight integrated day and night rolling curtain of the present embodiment comprises an upper bracket 1 and a lower bracket 2, a first rolling curtain assembly 3 is arranged on the upper bracket 1, and a second rolling curtain assembly 4 is arranged on the lower bracket 2, the first rolling curtain assembly 3 comprises a first roller 31 and a first curtain 32, one end of the first curtain 32 is connected to the first roller 31, and the other end of the first curtain 32 is detachably connected to the lower bracket 2, the second rolling curtain assembly 4 comprises a second roller 41 and a second curtain 42, one end of the second curtain 42 is connected to the second roller 41, and the other end of the second curtain 42 is connected to the tail plate 5, wherein one of the first curtain 32 and the second curtain 42 is a day curtain, and the other is a night curtain, and the day curtain has a different light transmittance than the night curtain; the first curtain 32 can be set as a day curtain, and the second curtain 42 can be set as a night curtain, that is, the day curtain is above the night curtain;

[0027] A power mechanism is provided in each of the first reel 31 and the second reel 41. The power mechanism includes a scroll spring energy storage member 6, a tubular motor 7 and a mechanical clutch assembly 8. The tubular motor 7 is transmission-connected to the corresponding first reel 31 and the second reel 41 through the mechanical clutch assembly 8. The output end of the mechanical clutch assembly 8 is transmission-connected to the corresponding first reel 31 and the second reel 41 through a rotating wheel. The output end of the mechanical clutch assembly 8 is fixedly connected to the rotating wheel, and the rotating wheel is clamped to the corresponding first reel 31 and the second reel 41. The scroll spring energy storage member 6 is transmission-connected to the corresponding first reel 31 and the second reel 41.

[0028] The outer rotating frame on the spiral spring energy storage member 6 is fixedly connected to the corresponding first drum 31 and the second drum 41. Taking the first drum 31 as an example, when the first drum 31 rotates, the torsion of the spiral spring energy storage member 6 can be stored or released at the same time, so that the first curtain 32 can stop at any position.

[0029] The torsion of the spiral spring energy storage member 6 in the first rolling curtain assembly 3 can be balanced with the common gravity of the first curtain fabric 32, the lower bracket 2, the tail plate 5 and the second rolling curtain assembly 4;

[0030] The torsion of the spiral spring energy storage member 6 in the second rolling curtain assembly 4 can be balanced with the common gravity of the second curtain fabric 42 and the tail plate 5 .

[0031] The arrangement of the mechanical clutch assembly 8 enables the first curtain 32 to descend or ascend when the user manually pulls downward or pushes upward the lower bracket 2. At this time, the first reel 31 rotates at the same time and can stop at any position under the action of the spiral spring energy storage member 6. During the rotation of the first reel 31, the mechanical clutch assembly 8 works and disengages, so that the output shaft of the motor does not rotate, thereby protecting the motor.

[0032] When the motor rotates, the mechanical clutch assembly 8 will be engaged, thereby transmitting the output power to the first reel 31, thereby electrically controlling the rise and fall of the first curtain 32;

[0033] Similarly, when the user manually pulls downward to push the tail plate 5 upward, the second curtain 42 will drop or rise, and the second roller 41 will rotate at the same time. Under the action of the volute spring energy storage member 6 at the second rolling curtain assembly 4, the second curtain 42 can stop at any position;

[0034] The first curtain 32 and the second curtain 42 can be stopped at any position, so as to adjust different light transmission ranges to meet different needs of customers.

[0035] Reference Figure 4 and Figure 5 As shown, the mechanical clutch assembly 8 is built-in or external to the tubular motor 7. The mechanical clutch assembly 8 can be arranged inside the tubular motor 7, thereby forming an integral body with the tubular motor 7;

[0036] The mechanical clutch assembly 8 may be arranged outside the tubular motor 7 , wherein preferably, the mechanical clutch assembly 8 may be arranged in cooperation with the rotating wheel, so as to reduce the space occupied by the mechanical clutch assembly 8 .

[0037] Reference Figure 5 As shown, the mechanical clutch assembly 8 includes an output member 81 and a clutch portion 82, the tubular motor 7 includes a motor assembly, the motor assembly includes a motor, generally, a reducer can be connected to the output end of the motor, the output end of the reducer is the output end of the motor assembly, the output member 81 is drivingly connected with the corresponding first reel 31 and second reel 41, the clutch portion 82 is arranged between the output member 81 and the output end of the motor assembly, and the clutch portion 82 is used to achieve the clutch between the output member 81 and the output end of the motor assembly;

[0038] Compared with the electromagnetic clutch, the mechanical clutch assembly 8 does not require the design of a control board, thereby reducing the use of control boards.

[0039] Reference Figure 5 As shown, the clutch part 82 includes an iron piece 821, a clutch piece 822 and a magnetic bead 823. The magnetic bead 823 is adsorbed on the iron piece 821 and is located on two opposite sides of the clutch piece 822. The clutch piece 822 is fixedly connected to the output end of the motor assembly. Two grooves matching the magnetic bead 823 are provided in the output piece 81. The iron piece 821 is fixedly connected to the tubular motor 7, and the output end of the motor assembly passes through the iron piece.

[0040] When the tubular motor 7 is working, the motor assembly drives the clutch 822 to rotate at the same time. The rotation of the clutch 822 pushes the magnetic beads 823 to move toward the corresponding grooves, so that the magnetic beads 823 are engaged between the corresponding grooves and the clutch 822, thereby driving the output member 81 to rotate, so that the corresponding first reel 31 and the second reel 41 rotate;

[0041] When the user manually pulls the second curtain 42, the second reel 41 will rotate. At this time, under the action of the rotating wheel, the torsional energy of the spiral spring energy storage member 6 can store or release energy at the same time, the output member 81 will rotate, and the magnetic bead 823, the clutch member 822 and the groove are in a disengaged state. The magnetic bead 823 will be adsorbed on the iron member 821 due to the adsorption force. Therefore, it will not affect the motor, thereby protecting the motor.

[0042] Reference Figure 5 As shown, the iron piece 821 is fixedly connected to the end cover of the tubular motor 7, the motor assembly or the outer tube of the tubular motor.

[0043] When the iron piece 821 is fixedly connected to the end cover of the tubular motor 7, the mechanical clutch assembly 8 is placed outside the tubular motor 7, the end cover of the tubular motor 7 is fixedly connected to the outer tube, and the iron piece can be fixedly connected to the end surface of the end cover;

[0044] When the iron piece 821 is fixedly connected to the motor assembly or the outer tube of the tubular motor, the mechanical clutch assembly is built into the tubular motor;

[0045] Among them, the end of the reducer on the motor assembly is fixedly connected to the iron piece, and the output end of the reducer passes through the iron sheet and will not interfere with the iron sheet.

[0046] When the iron piece is fixedly connected to the outer tube of the tubular motor, the iron piece is located inside the outer tube of the tubular motor and is fixed to the inner wall of the outer tube.

[0047] A first bearing 811 is connected between the output member 81 and the end cover of the tubular motor 7 , which can increase the coaxiality between the output member 81 and the output end of the motor assembly. In this solution, the mechanical clutch assembly 8 is built into the tubular motor 7 .

[0048] The clutch part 82 further includes an input member 824, the iron member 821 is fixedly connected to the input member 824, and the input member 824 is fixedly connected to the end cover of the tubular motor 7, the outer tube of the tubular motor or the motor assembly;

[0049] When the input member 824 is disposed on the motor assembly, the input member 824 can be disposed on the housing of the reducer, and the iron member 821 can be fixedly connected to the input member 824, thereby avoiding the situation where there is insufficient space on the housing of the reducer;

[0050] Preferably, there is a gap between the input member 824 and the clutch member 822, and the iron member 821 includes an extension section, which extends into the gap, thereby forming a positioning of the iron member 821, which is convenient for the installation of the iron member 821;

[0051] At least one first plane is formed on the side of the extension section of the iron piece 821, and a second plane matching the first plane is formed at the input piece 824, thereby limiting the circumferential rotation of the iron piece 821, and the iron piece 821 will not rotate with the rotation of the output end of the tubular motor 7.

[0052] The input member 824 can also be arranged on the end cover of the tubular motor 7. The iron member 821 is fixedly connected to the input member 824. When the mechanical clutch assembly 8 is externally arranged, insufficient space on the end cover of the tubular motor 7 can be avoided.

[0053] The input member 824 may also be disposed on the outer tube of the tubular motor. In this case, the input member 824 is located inside the outer tube of the tubular motor 7 and is fixedly connected to the inner wall of the outer tube.

[0054] The output member 81 is rotationally connected to the input member 824 , wherein a second bearing may be connected between the output member 81 and the input member 824 , so that the central axis of the output member 81 can coincide with the central axis of the input member 824 .

[0055] Reference Figure 4 As shown, the tubular motor 7 has a built-in lithium battery 9 or an external power cord. Preferably, the tubular motor 7 located in the first rolling curtain assembly 3 is connected to an external power cord. Since the tubular motor 7 in the first rolling curtain assembly 3 does not move up or down, its height position is constant, and the power cord can provide long-term power supply.

[0056] The tubular motor 7 located in the second roller blind assembly 4 has a built-in lithium battery 9, which can be charged through a charging interface. Since the position height of the tubular motor 7 in the second roller blind assembly 4 is uncertain, it will rise and fall simultaneously with the rise and fall of the first curtain 32, so the design of a built-in lithium battery 9 is more suitable, wherein the charging interface of the tubular motor 7 exposes the second roller 41 for easy charging.

[0057] An accommodating cavity 11 is formed in the upper bracket 1, and the accommodating cavity 11 is used to accommodate the first rolling curtain assembly 3, the second rolling curtain assembly 4 and the lower bracket 2. When the first curtain 32 and the second curtain 42 are both retracted, the first rolling curtain assembly 3, the second rolling curtain assembly 4 and the lower bracket 2 can be hidden in the accommodating cavity 11, and the user cannot observe them from the outside, which has a good aesthetics. In addition, the tail plate 5 can be exposed from the upper bracket 1, and the user can intuitively see the position of the tail plate 5, so as to manually pull the tail plate 5;

[0058] Of course, as required, the tail plate 5 can be designed to be hidden.

[0059] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
