[0025] The best embodiment of this utility model

[0026] 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.

[0027] Referring to Figures 1, 2, and 3, this embodiment of a flashlight-integrated day and night roller blind includes an upper support 1 and a lower support 2. A first roller blind assembly 3 is mounted on the upper support 1, and a second roller blind assembly 4 is mounted on the lower support 2. The first roller blind assembly 3 includes 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 is detachably connected to the lower support 2. The second roller blind assembly 4 includes 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 is connected to a tail plate 5. One of the first curtain 32 and the second curtain 42 is a day blind, and the other is a night blind. The day blind and the night blind have different light transmittance. The first curtain 32 can be set as a day blind, and the second curtain 42 can be set as a night blind, i.e., the day blind is above the night blind.

[0028] Both the first drum 31 and the second drum 41 are equipped with a power mechanism, which includes a spiral spring energy storage component 6, a tubular motor 7, and a mechanical clutch assembly 8. The tubular motor 7 is connected to the corresponding first drum 31 and the corresponding second drum 41 through the mechanical clutch assembly 8. The output end of the mechanical clutch assembly 8 is connected to the corresponding first drum 31 and the corresponding second drum 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 engaged with the corresponding first drum 31 and the corresponding second drum 41. The spiral spring energy storage component 6 is connected to the corresponding first drum 31 and the corresponding second drum 41.

[0029] Among them, the outer rotating frame on the spiral spring energy storage component 6 is fixedly connected to the corresponding first drum 31 and second drum 41. Taking the first drum 31 as an example: when the first drum 31 rotates, the torque of the spiral spring energy storage component 6 can be stored or released simultaneously, so that the first curtain 32 can stop at any position.

[0030] Among them, the torque of the spiral spring energy storage component 6 located in the first roller blind assembly 3 can be balanced with the combined gravity of the first curtain 32, the lower bracket 2, the tail plate 5 and the second roller blind assembly 4.

[0031] The torque of the spiral spring energy storage component 6 located in the second roller blind assembly 4 can be balanced with the combined gravity of the second curtain fabric 42 and the tail plate 5.

[0032] The mechanical clutch assembly 8 is designed so that when the user manually pulls down or pushes up the lower bracket 2, the first curtain 32 will descend or rise. At this time, the first drum 31 will rotate simultaneously, and under the action of the spiral spring energy storage component 6, it can stop at any position. During the rotation of the first drum 31, the mechanical clutch assembly 8 will be activated and disengaged, so that the output shaft of the motor will not rotate, thereby protecting the motor.

[0033] When the motor rotates, the mechanical clutch assembly 8 engages, thereby transmitting the output power to the first drum 31, thus realizing the electric control of the raising and lowering of the first curtain 32;

[0034] Similarly, when the user manually pulls down and pushes the tail plate 5 upward, the second curtain 42 will descend or rise, and the second roller 41 will rotate at the same time. Under the action of the spiral spring energy storage component 6 at the second roller blind assembly 4, the second curtain 42 can stop at any position.

[0035] This allows both the first curtain 32 and the second curtain 42 to be stopped at any position, thereby adjusting different light transmission ranges to meet different customer needs.

[0036] Referring to Figures 4 and 5, the mechanical clutch assembly 8 can be built into or external to the tubular motor 7. The mechanical clutch assembly 8 can be set inside the tubular motor 7, thus forming an integral part with the tubular motor 7.

[0037] The mechanical clutch assembly 8 can be installed outside the tubular motor 7. Preferably, the mechanical clutch assembly 8 can be installed in conjunction with the rotary wheel to reduce the space occupied by the mechanical clutch assembly 8.

[0038] Referring to Figure 5, the mechanical clutch assembly 8 includes an output component 81 and a clutch part 82. The tubular motor 7 includes a motor assembly, which 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 component 81 is connected to the corresponding first drum 31 and second drum 41. The clutch part 82 is disposed between the output component 81 and the output end of the motor assembly. The clutch part 82 is used to realize the engagement and disengagement between the output component 81 and the output end of the motor assembly.

[0039] Compared to electromagnetic clutches, mechanical clutch assembly 8 eliminates the need for a control board, thus reducing the use of control boards.

[0040] Referring to FIG5, the clutch part 82 includes an iron part 821, a clutch part 822, and a magnetic bead 823. The magnetic bead 823 is attracted to the iron part 821 and is located on opposite sides of the clutch part 822. The clutch part 822 is fixedly connected to the output end of the motor assembly. Two grooves that cooperate with the magnetic bead 823 are provided in the output part 81. The iron part 821 is fixedly connected to the tubular motor 7, and the output end of the motor assembly passes through the iron part.

[0041] When the tubular motor 7 is working, the motor assembly will drive the clutch 822 to rotate simultaneously. The rotation of the clutch 822 will push the magnetic bead 823 to move toward the corresponding groove, so that the magnetic bead 823 is engaged between the corresponding groove and the clutch 822, thereby driving the output component 81 to rotate, so that the corresponding first drum 31 and second drum 41 rotate.

[0042] When the user manually pulls the second curtain 42, the second drum 41 will rotate. At this time, under the action of the rotating wheel, the torque of the spiral spring energy storage component 6 can be stored or released simultaneously, the output component 81 will rotate, the magnetic bead 823, the clutch component 822 and the groove are in a disengaged state, the magnetic bead 823 will be attracted to the iron part 821 due to the attraction force, so it will not affect the motor, thus protecting the motor.

[0043] Referring to Figure 5, the iron part 821 is fixedly connected to the end cap, motor assembly, or outer tube of the tubular motor 7.

[0044] When the iron part 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 part can be fixedly connected to the end face of the end cover.

[0045] When the iron part 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;

[0046] In this motor assembly, the end of the reducer is fixedly connected to the iron piece, and the output end of the reducer passes through the iron piece without interfering with it.

[0047] When the iron part is fixedly connected to the outer tube of the tubular motor, the iron part is located inside the outer tube of the tubular motor, and a fixed connection is formed between it and the inner wall of the outer tube.

[0048] A first bearing 811 is connected between the output component 81 and the end cover of the tubular motor 7, which can increase the coaxiality between the output component 81 and the output end of the motor assembly. In this scheme, the mechanical clutch assembly 8 is built into the tubular motor 7.

[0049] The clutch part 82 also includes an input part 824. The iron part 821 is fixedly connected to the input part 824. The input part 824 is fixedly connected to the end cover of the tubular motor 7, the outer tube of the tubular motor, or the motor assembly.

[0050] When the input component 824 is installed on the motor assembly, the input component 824 can be installed on the housing of the reducer, and the iron part 821 can be fixedly connected to the input component 824, which can avoid the situation of insufficient space on the housing of the reducer.

[0051] Preferably, there is a gap between the input component 824 and the clutch component 822, and the iron component 821 includes an extension section that extends into the gap, thereby positioning the iron component 821 and facilitating the installation of the iron component 821.

[0052] The side of the extension of the iron part 821 is provided with at least one first plane, and the input part 824 is provided with a second plane that cooperates with the first plane, thereby restricting the circumferential rotation of the iron part 821. The iron part 821 will not rotate with the rotation of the output end of the tubular motor 7.

[0053] The input component 824 can also be set on the end cover of the tubular motor 7. The iron part 821 is fixedly connected to the input component 824. When the mechanical clutch assembly 8 is external, the insufficient space on the end cover of the tubular motor 7 can be avoided.

[0054] The input component 824 can also be set on the outer tube of the tubular motor. In this case, the input component 824 is located inside the outer tube of the tubular motor 7 and is fixedly connected to the inner wall of the outer tube.

[0055] The output component 81 and the input component 824 are rotatably connected, wherein a second bearing can be connected between the output component 81 and the input component 824, so that the central axis of the output component 81 can coincide with the central axis of the input component 824.

[0056] Referring to Figure 4, 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 roller blind assembly 3 has an external power cord. Since the tubular motor 7 in the first roller blind assembly 3 does not lift or lower, its height position is fixed, and the power cord can provide power for a long time.

[0057] The tubular motor 7 located in the second roller blind assembly 4 has a built-in lithium battery 9, which can be charged through the charging interface. Since the position and height of the tubular motor 7 in the second roller blind assembly 4 are not fixed, it will rise and fall simultaneously with the rise and fall of the first curtain 32, making the design of the built-in lithium battery 9 more suitable. The charging interface of the tubular motor 7 is exposed on the second roller 41 for easy charging.

[0058] The upper support 1 has a receiving cavity 11, which is used to accommodate the first roller blind assembly 3, the second roller blind assembly 4 and the lower support 2. When the first curtain 32 and the second curtain 42 are both retracted, the first roller blind assembly 3, the second roller blind assembly 4 and the lower support 2 can be hidden in the receiving cavity 11, and the user cannot see them from the outside, which is aesthetically pleasing. In addition, the tail plate 5 can be exposed on the upper support 1, and the user can see the position of the tail plate 5 directly, so as to manually pull the tail plate 5.

[0059] Of course, depending on the needs, the tailgate 5 can also be designed to be hidden.

[0060] 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.
