Description

Technical Field

[0001] This application relates to the technical field of tubular motors, and more particularly to a tubular motor with a power supply module. Background Technology

[0002] Generally, tubular motors are used in motorized curtains, motorized honeycomb blinds, motorized screens, etc.

[0003] Among the related technologies, there is a curtain tubular motor, which mainly includes a motor, a circuit board and a lithium battery. The circuit board has circuit components that are connected to the motor to control the motor's switching and forward / reverse rotation. The lithium battery powers the motor and the circuit board and has a charging port for charging, allowing the lithium battery to be used repeatedly.

[0004] Regarding the aforementioned technologies, lithium batteries have a limited capacity and need to be charged after a few weeks or months of use. Users insert the charging cable into the charging port of the lithium battery. However, tubular motors are usually located at the top of the curtains, which is relatively high. Each time a charge is needed, users have to climb stairs to reach the charging port, which is quite inconvenient. Utility Model Content

[0005] To facilitate users in charging lithium batteries, this application provides a tubular motor with a power supply module.

[0006] This application provides a tubular motor with a power supply module, which adopts the following technical solution: A tubular motor with a power supply module includes a motor, a circuit controller electrically connected to the motor, and a power supply module connected to the circuit controller. The power supply module includes a pull cord switch, a wire, and a lithium battery. One end of the wire is flexibly connected to the circuit controller, and the other end is connected to the lithium battery. The pull cord switch includes a switch body and a pull wire. The switch body is connected to the circuit controller, and one end of the pull wire is connected to the switch body, while the other end is connected to the lithium battery. The lithium battery has a charging port.

[0007] By adopting the above technical solution, the lithium battery hangs down via a wire, and the height of the lithium battery is adjustable via the wire, making it convenient for users to charge the lithium battery through the charging port.

[0008] Optionally, the switch body includes a housing, a support shaft installed in the housing, a polygonal wheel rotatably sleeved on the support shaft, a dial ring rotatably sleeved on the support shaft and driving the polygonal wheel to rotate, and an elastic conductive sheet abutting against the polygonal wheel. The polygonal wheel has multiple abutting surfaces that abut against the elastic conductive sheet. The multiple abutting surfaces are spaced apart with electrically conductive sheets that can abut against the elastic conductive sheet. The pull wire is connected to the dial ring, and the support shaft is provided with a torsion spring that drives the dial ring to reset.

[0009] By adopting the above technical solution, when the tubular motor is started, the user grasps the pull cable and moves it downwards, thereby causing the pull cable to drive the dial ring to rotate. The rotating dial ring drives the polygonal wheel to rotate, causing the elastic conductive sheet to come into contact with the electrical conductive sheet, thus completing the circuit and starting the tubular motor.

[0010] Optionally, a transmission block is provided on the side of the dial ring near the polygonal rotating wheel, and the polygonal rotating wheel is provided with a transmission groove for the transmission block to enter.

[0011] By adopting the above technical solution, the transmission block abuts against the groove wall of the transmission groove, so that the dial ring can drive the polygonal wheel to rotate when it rotates, thereby making the elastic conductive sheet contact different support surfaces.

[0012] Optionally, the transmission block has a guide ramp that facilitates sliding out of the transmission groove.

[0013] By adopting the above technical solution, the guide slope makes it easier for the transmission block to slide out of the transmission groove when the circlip is reset.

[0014] Optionally, some of the described wires may overlap with the pull wire.

[0015] By adopting the above technical solution, the pull cord and the power cord partially overlap, and the overlapping part can be made into a wire harness to improve the overall aesthetics. At the same time, the user can also control the switch body by grabbing and pulling the lithium battery, which makes it more convenient for the user to pull the pull cord to a certain extent.

[0016] Optionally, the lithium battery has an outer casing, and the charging port is disposed on the casing.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. The lithium battery hangs down via a wire, which allows the height of the lithium battery to be adjusted, making it convenient for users to charge the lithium battery through the charging port; 2. When the tubular motor starts, the user grasps the lithium battery and pulls the cable downwards, which in turn causes the pull cable to rotate the dial. The rotating dial causes the polygonal wheel to rotate, causing the elastic conductive plate to come into contact with the conductive plate, thus completing the circuit and starting the tubular motor.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a tubular motor with a power supply module.

[0028] Reference Figure 1 and Figure 2 The tubular motor includes a motor 1, a circuit controller 2 electrically connected to the motor 1, and a power supply module 3. The circuit controller 2 has a circuit board and electronic components, and the circuit controller 2 is connected to the motor 1 through a line. The power supply module 3 is connected to the circuit controller 2 and provides power to the circuit controller 2 through the power supply module 3.

[0029] The power supply module 3 includes a pull-cord switch 31, a wire 32, and a lithium battery 33. The pull-cord switch 31 is connected to the circuit controller 2 and controls the start and stop of the motor 1. One end of the wire 32 is flexibly connected to the circuit controller 2, and the other end is connected to the lithium battery 33, providing power to the circuit controller 2 through the lithium battery 33. In actual use, the wire 32 is external and hangs down, allowing the height of the lithium battery 33 to be adjusted for easy charging by the user. In this embodiment, the flexible connection means that the end of the wire 32 near the circuit controller 2 has a slack, so that the end of the wire 32 will not disconnect from the circuit controller 2 after moving a certain distance.

[0030] See Figure 3The pull cord switch 31 includes a switch body 311 and a pull cord 312. The pull cord 312 is connected to the switch body 311, and the switch body 311 is opened or closed by pulling the pull cord 312. The pull cord 312 is external and hangs down, making it convenient for the user to pull the cord 312. The pull cord 312 and the wire 32 partially overlap, and the overlapping part can be made into a wire harness to improve the overall aesthetics. At the same time, the user can also pull the switch body 311 by grasping and pulling the lithium battery 33, which makes it more convenient for the user to pull the cord 312. Of course, in actual use, the lithium battery 33 will be wrapped with an insulating layer to prevent electric shock when the user comes into contact with the lithium battery 33.

[0031] See Figure 4 and Figure 5 The switch body 311 includes a housing 313, a support shaft 314, a polygonal rotating wheel 315, and a dial ring 316. The support shaft 314 is fixedly installed inside the housing 313. The polygonal rotating wheel 315 and the dial ring 316 are rotatably connected to the support shaft 314 and abut against each other. One end of the pull wire 312 is connected to the dial ring 316, and the other end hangs down. The pull wire 312 pulls the dial ring 316, and the dial ring 316 then drives the polygonal rotating wheel 315 to rotate.

[0032] The polygonal wheel 315 has multiple support surfaces 317, and in this embodiment, six support surfaces are provided. Conductive plates 318 are mounted on the multiple support surfaces 317, and in this embodiment, three conductive plates 318 are provided, spaced equidistantly on the six support surfaces 317. A metal plate 3131 is connected to the housing 313 by screws. The metal plate 3131 abuts against the conductive plates 318, allowing the metal plate 3131 and the conductive plates 318 to conduct current to each other.

[0033] The switch body 311 also includes an elastic conductive sheet 319, which, along with the metal sheet 3131, is connected to the circuit controller 2 via wiring. One end of the elastic conductive sheet 319 is connected to the housing 313 by a screw, and the other end elastically abuts against the support surface 317, allowing the elastic conductive sheet 319 to contact different support surfaces 317 when the polygonal rotating wheel 315 rotates. Furthermore, the elastic conductive sheet 319 can contact the conductive sheet 318, enabling current to be conducted between the elastic conductive sheet 319 and the conductive sheet 318, thereby allowing current to flow between the metal sheet 3131 and the elastic conductive sheet 319.

[0034] In order to enable the derailleur 316 to return to its original position after being pulled by the cable 312, a torsion spring 3141 is sleeved on the support shaft 314. One end of the torsion spring 3141 is fixedly connected to the housing 313 or the support shaft 314, and the other end is fixedly connected to the derailleur 316. The torsion spring 3141 enables the derailleur 316 to return to its original position after rotating on the support shaft 314.

[0035] See Figure 6 and Figure 7 To enable the dial ring 316 to drive the polygonal wheel 315 to rotate, a transmission block 3161 is integrally provided on the side of the dial ring 316 near the polygonal wheel 315. The polygonal wheel 315 has a transmission groove 3151 for the transmission block 3161 to enter. Under normal conditions, the transmission block 3161 is located in the transmission groove 3151. The transmission block 3161 abuts against the groove wall of the transmission groove 3151, so that the dial ring 316 can drive the polygonal wheel 315 to rotate when it rotates, thereby making the elastic conductive sheet 319 contact with different support surfaces 317.

[0036] To facilitate the sliding of the transmission block 3161 out of the transmission groove 3151, the transmission block 3161 has an inclined guide slope 3162. The guide slope 3162 makes it easier for the transmission block 3161 to slide out of the transmission groove 3151 when the dart ring 316 is reset.

[0037] The implementation principle of a tubular motor with a power supply module in this application embodiment is as follows: When the tubular motor is started, the user grasps the lithium battery 33 and moves the pull cable 312 downward, thereby causing the pull cable 312 to drive the dial ring 316 to rotate. The rotating dial ring 316 drives the polygonal wheel to rotate 315, so that the elastic conductive sheet 319 abuts against the electrical conductive sheet 318, the circuit is connected, and the tubular motor is started; when shutting down, the pull cable 312 is pulled again, and the elastic conductive sheet 319 contacts the surface 317 without the electrical conductive sheet 318, and the circuit is disconnected.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
