[0002] Currently, the main type of cord winding device used in electrical appliances such as air conditioners is the disc winding method. A coil spring is installed inside the disc to wind the wire outward from the center, thus achieving the purpose of winding up the wire. However, the length of wire that can be collected by this method is limited by the radius of the coil, and the rotational torque as the wire bundle is wound also puts a significant strain on the coil spring.

[0015] In a preferred embodiment of the present invention, a second spur gear is disposed near the first spur gear, the second spur gear meshes with the first spur gear, and the rotation of the first spur gear drives the second spur gear to rotate.

[0016] In a preferred embodiment of the present invention, the power module further includes a second lead screw, a second spur gear is sleeved on the second lead screw, and a first lead screw nut is connected to the end face of the second spur gear, the first lead screw nut being sleeved on the second lead screw.

[0037] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0038] Example 1

[0039] like Figure 1 , Figure 8 and Figure 9 As shown, this embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley group on which a wire 3 is wound. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first direction and the second direction intersect.

[0040] Preferably, the first direction and the second direction are perpendicular to each other. After the take-up module 1 is installed, as the take-up module 1 moves toward the power module 2 in the second direction, the wire 3 wound on the movable pulley block changes from moving toward the first direction to moving toward the second direction after passing through the steering mechanism.

[0041] Driven by the power module 2, the take-up module 1 moves in the first direction and retracts the wire 3 in the second direction, so that the take-up module 1 can move and retract the wire 3 at the same time.

[0042] like Figure 4 As shown, the movable pulley assembly includes a movable pulley 9 and a sliding pin 24, with the movable pulley 9 fitted onto the sliding pin 24. Preferably, a baffle is provided at the top of the sliding pin 24 to axially limit the movable pulley 9 and prevent it from moving axially. In this embodiment, the movable pulley assembly includes two movable pulleys 9. The movable pulley 9 rotates around the central axis of the sliding pin 24, reducing the force on the wire 3 wound on the movable pulley 9 to half of its original value, thus reducing the torque required when winding the wire.

[0043] After passing through two movable pulleys 9, the wire 3 is turned by a steering mechanism, dividing it into multiple segments of equal length. When the take-up module 1 moves in the first direction, its displacement in the first direction is four times the take-up length of the movable pulleys 9 in the second direction.

[0044] By setting a first direction and a second direction, the movement direction of the take-up module 1 is separated from the retraction direction of the wire 3, which greatly reduces the space required by the take-up device and solves the problem that the existing power take-up device is constrained by space size.

[0045] This embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley system with a wire 3 wound on it. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first and second directions intersect. The power module 2 drives the take-up module 1 to move in the first direction, and the movable pulley system moves along with the take-up module 1 in the first direction. Under the action of the steering mechanism, the movement direction of the wire 3 is adjusted from the first direction to the second direction, causing the wire 3 wound on the movable pulley system to move in the second direction. During the movement of the take-up module 1 driven by the power module 2, the wire 3 is retracted in the second direction. The above-mentioned take-up device separates the movement direction of the take-up module 1 from the retraction direction of the wire 3, making full use of the space of the take-up device, reducing the size requirements of the take-up device, and solving the problem of the large space constraints of existing power supply take-up devices. It can achieve the retraction of the wire 3 in a small space. With the help of the movable pulley system, the take-up module 1 can retract the wire 3 while moving, and can also reduce the torque required for take-up.

[0046] Example 2

[0047] like Figure 1 , Figure 8 and Figure 9As shown, this embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley group on which a wire 3 is wound. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first direction and the second direction intersect.

[0048] like Figures 2-4 As shown, the take-up module 1 also includes a slider 5 and a first lead screw 6. The slider 5 has a through hole 7, and the first lead screw 6 is inserted into the through hole 7. When the first lead screw 6 rotates, it drives the slider 5 to move towards or away from the power module 2.

[0049] The winding device also includes a lampshade 4, on which a slide rail 8 is provided. The slider 5 is inserted into the slide rail 8, and the slide rail 8 is used to guide the slider 5.

[0050] The steering mechanism includes a fixed pulley assembly, which is located on the side of the lamp cover 4 away from the power module 2. The fixed pulley assembly is used to change the direction of movement of the wire 3.

[0051] The fixed pulley block and the power module 2 are respectively located on opposite sides of the lampshade 4. The movable pulley block is located on top of the slider 5. When the slider 5 moves on the slide rail 8, the movable pulley block moves along with the slider 5 on the slide rail 8. For example, when the wire 3 is being retrieved, the slider 5 is initially positioned on the side of the slide rail 8 closest to the fixed pulley block. The first lead screw 6 rotates clockwise, causing the slider 5 to move towards the power module 2. During the movement of the slider 5, the wire 3 is continuously retrieved until the slider 5 moves to the side of the slide rail 8 closest to the power module 2. When the wire 3 is being released, the slider 5 is initially positioned on the side of the slide rail 8 closest to the power module 2. The first lead screw 6 rotates counterclockwise, causing the slide rail 8 to move away from the power module 2. During the movement of the slider 5, the wire 3 is continuously released until the slider 5 moves to the side of the slide rail 8 closest to the fixed pulley block.

[0052] like Figures 2-3 As shown, flanges 23 are provided on both sides of the slide rail 8. The flanges 23 are lowered relative to the plane of the lamp cover 4 where the fixed pulley group is located, so that after the slider 5 is inserted into the slide rail 8, the movable pulley group on the slider 5 and the fixed pulley group on the lamp cover 4 are in the same horizontal plane, thereby keeping the wire 3 wound on the fixed pulley 10 and the wire 3 wound on the movable pulley 9 moving in the same horizontal plane.

[0053] like Figures 2-4As shown, a second lead screw nut is installed in the through hole 7 of the slider 5. The first lead screw 6 passes through the slider 5, so that the second lead screw nut is sleeved on the first lead screw 6. The slider 5 is mounted on the slide rail 8 and can only move along the extension direction of the slide rail 8. When the first lead screw 6 rotates, it drives the second lead screw nut to rotate through sliding friction, thereby driving the slider 5 to move in the second direction or the fourth direction, where the fourth direction is the opposite direction of the second direction.

[0054] The fixed pulley system can change the direction of movement of the wire 3. Under the action of the fixed pulley system, the wire 3, which was originally moving in the first direction, is changed to move in the second direction, and the wire 3 is retrieved in the second direction.

[0055] The winding device in this embodiment also includes a lampshade 4, on which a slide rail 8 is provided. The slider 5 is inserted into the slide rail 8, which guides the slider 5. When the winding device winds up the wire, the power module 2 drives the first lead screw 6 to rotate clockwise. Under the guidance of the slide rail 8, the first lead screw 6 drives the slider 5 to move towards the direction closer to the power module 2, i.e., the second direction. During the movement of the slider 5, the wire 3 is retrieved through a movable pulley system. By using a fixed pulley system to change the direction of movement of the wire 3, the retrieval direction of the wire 3 is separated from the direction of movement of the winding device, making full use of the space of the winding device and reducing the size requirements of the winding device. The movable pulley system has the characteristic of saving effort, and using a movable pulley system can reduce the torque required for winding up the wire.

[0056] Example 3

[0057] like Figure 1 As shown, this embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley group on which a wire 3 is wound. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first direction and the second direction intersect.

[0058] like Figures 2-4 As shown, the take-up module 1 also includes a slider 5 and a first lead screw 6. The slider 5 has a through hole 7, and the first lead screw 6 is inserted into the through hole 7. When the first lead screw 6 rotates, it drives the slider 5 to move towards or away from the power module 2.

[0059] The winding device also includes a lampshade 4, on which a slide rail 8 is provided. The slider 5 is inserted into the slide rail 8, and the slide rail 8 is used to guide the slider 5.

[0060] The steering mechanism includes a fixed pulley assembly, which is located on the side of the lamp cover 4 away from the power module 2. The fixed pulley assembly is used to change the direction of movement of the wire 3.

[0061] The movable pulley group includes several movable pulleys 9, and the fixed pulley group includes several fixed pulleys 10. The wire 3 is alternately wound around the movable pulleys 9 and the fixed pulleys 10.

[0062] The lampshade 4 has a mounting hole 11 on the side near the fixed pulley group. The first end of the first lead screw 6 is installed in the mounting hole 11, and the second end of the first lead screw 6 is connected to the power module 2.

[0063] This embodiment uses a movable pulley system comprising two movable pulleys 9 and a fixed pulley system comprising three fixed pulleys 10 as an example. The wire 3 is introduced from one side of the fixed pulley system via a fixed pulley 10, and is alternately wound around the fixed pulleys 10 and 9, finally exiting from the other side of the fixed pulley system via a fixed pulley 10. Combining the movable and fixed pulley systems, the length of the lampshade 4 moving along the first direction is divided into four segments along the second direction by the three fixed pulleys 10. Therefore, the speed at which the lampshade 4 moves along the first direction is four times the speed at which the wire 3 is retrieved along the second direction, and the total length of the wire retrieved along the second direction is equal to the distance the lampshade 4 moves along the first direction.

[0064] Using three fixed pulleys 10 can change the direction of movement of the wire 3. According to the principle that the movable pulley 9 saves effort but increases the length of the wire, the force on each segment of the wire 3 on the two movable pulleys 9 is one-quarter of the thrust of the first lead screw 6 in the second direction. The sum of the lengths of the wires wound by the two movable pulleys 9 is four times the displacement of the slider 5 in the second direction.

[0065] like Figure 3 and Figure 9 As shown, the first end of the first lead screw 6 is inserted into the mounting hole 11, and the mounting hole 11 axially limits the first lead screw 6. The power module 2 drives the first lead screw 6 to rotate clockwise or counterclockwise, thereby driving the slider 5 and the movable pulley group to move in the second or fourth direction, wherein the fourth direction is opposite to the second direction.

[0066] The movable pulley group in this embodiment includes several movable pulleys 9, and the fixed pulley group includes several fixed pulleys 10. The wire 3 is alternately wound around the movable pulleys 9 and the fixed pulleys 10. The take-up module 1 uses two movable pulleys 9 combined with three fixed pulleys 10. Utilizing the principle that the fixed pulleys 10 change the direction of force and the movable pulleys 9 can save effort, the power module 2 drives the first lead screw 6 to rotate, thereby driving the slider 5 and the movable pulleys 9 to move in the second or fourth direction. When the slider 5 moves in the second direction, the take-up module 1 retracts the wire 3; when the slider 5 moves in the fourth direction, the take-up module 1 releases the wire 3. Using the movable pulleys 9 allows for simultaneous movement and take-up, and also reduces the torque required for take-up.

[0067] Example 4

[0068] like Figure 1 , Figure 8 and Figure 9 As shown, this embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley group on which a wire 3 is wound. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first direction and the second direction intersect.

[0069] like Figures 2-4 As shown, the take-up module 1 also includes a slider 5 and a first lead screw 6. The slider 5 has a through hole 7, and the first lead screw 6 is inserted into the through hole 7. When the first lead screw 6 rotates, it drives the slider 5 to move towards or away from the power module 2.

[0070] The winding device also includes a lampshade 4, on which a slide rail 8 is provided. The slider 5 is inserted into the slide rail 8, and the slide rail 8 is used to guide the slider 5.

[0071] like Figures 5-6 As shown, the power module 2 includes a first bevel gear 12, and the second end of the first lead screw 6 is connected to the first bevel gear 12. When the first bevel gear 12 rotates, it drives the first lead screw 6 to rotate.

[0072] The power module 2 also includes a motor 13, on which a first spur gear 14 and a second bevel gear 15 are mounted. When the drive shaft rotates, it drives the first spur gear 14 and the second bevel gear 15 to rotate.

[0073] The winding device is powered by the power module 2. The motor 13 provides power to the entire power module 2. When the motor 13 is started, the power module 2 begins to work.

[0074] The second bevel gear 15 is positioned close to the first bevel gear 12, and a first spur gear 14 is positioned between the second bevel gear 15 and the motor 13. The drive shaft drives the first spur gear 14 and the second bevel gear 15 to rotate counterclockwise synchronously. The second bevel gear 15 meshes with the first bevel gear 12, and the counterclockwise rotation of the second bevel gear 15 drives the first bevel gear 12 to rotate clockwise, thereby driving the first lead screw 6 to rotate clockwise. The first lead screw 6 drives the slider 5 to move within the slide rail 8 in the direction closer to the power module 2, i.e., the second direction. During the movement of the slider 5 in the second direction, the wire 3 is retracted.

[0075] When the take-up device releases the lead wire 3, the drive shaft of the motor 13 rotates clockwise, driving the first spur gear 14 and the second bevel gear 15 to rotate clockwise simultaneously. The second bevel gear 15 meshes with the first bevel gear 12, and the clockwise rotation of the second bevel gear 15 drives the first bevel gear 12 to rotate counterclockwise, thereby causing the first bevel gear 12 to rotate counterclockwise. The first lead screw 6 drives the slider 5 to move within the slide rail 8 in the fourth direction away from the power module 2, releasing the lead wire 3 during the movement of the slider 5 in the fourth direction.

[0076] In this embodiment, the first bevel gear 12 and the second bevel gear 15 mesh. When the take-up device retracts the wire 3, the motor 13 drives the second bevel gear 15 to rotate counterclockwise, which in turn drives the first bevel gear 12 to rotate clockwise, thereby causing the first lead screw 6 to rotate clockwise. The first lead screw 6 drives the slider 5 to move towards the power module 2, so that the slider 5 retracts the wire 3 during the movement.

[0077] Example 5

[0078] like Figure 1 , Figure 8 and Figure 9 As shown, this embodiment provides a wire take-up device, including a take-up module 1 and a power module 2. The take-up module 1 includes a movable pulley group on which a wire 3 is wound. The take-up module 1 and the power module 2 are connected. The power module 2 drives the take-up module 1 to move in a first direction. A steering mechanism adjusts the movement direction of the wire 3 from the first direction to a second direction to retract the wire 3. The first direction and the second direction intersect.

[0079] like Figure 2 As shown, the power module 2 includes a first bevel gear 12, and the second end of the first lead screw 6 is connected to the first bevel gear 12. When the first bevel gear 12 rotates, it drives the first lead screw 6 to rotate.

[0080] like Figure 5As shown, the power module 2 also includes a motor 13, on which a first spur gear 14 and a second bevel gear 15 are mounted. When the drive shaft rotates, it drives the first spur gear 14 and the second bevel gear 15 to rotate.

[0081] A second spur gear 16 is disposed near the first spur gear 14. The second spur gear 16 meshes with the first spur gear 14. When the first spur gear 14 rotates, it drives the second spur gear 16 to rotate.

[0082] The power module 2 also includes a second lead screw 17, a second spur gear 16 is sleeved on the second lead screw 17, and a first lead screw nut 18 is connected to the end face of the second spur gear 16. The first lead screw nut 18 is sleeved on the second lead screw 17.

[0083] like Figures 5-7 As shown, the power module 2 also includes a protective cover 19, in which the first spur gear 14 and the second spur gear 16 are disposed; the protective cover 19 is connected to the first lead screw nut 18, and the side of the protective cover 19 adjacent to the first lead screw nut 18 is connected to the lamp cover 4.

[0084] like Figure 2 and Figure 5 As shown, a first lead screw nut 18 is provided on the end face of the second spur gear 16, and the first lead screw nut 18 is located below the second bevel gear 15. When the wire 3 is retracted, the drive shaft of the motor 13 rotates counterclockwise, the first spur gear 14 rotates counterclockwise, the second spur gear 16 meshes with the first spur gear 14, the second spur gear 16 rotates clockwise, and the first lead screw nut 18 rotates clockwise, thereby driving the lampshade 4 to move in the fifth direction. When the wire 3 is released, the drive shaft of the motor 13 rotates clockwise, the first spur gear 14 rotates clockwise, the second spur gear 16 meshes with the first spur gear 14, the second spur gear 16 rotates counterclockwise, and the first lead screw nut 18 rotates counterclockwise, thereby driving the lampshade 4 to move in the sixth direction, which is opposite to the fifth direction.

[0085] The sliding of slider 5 on slide rail 8 and the movement of lampshade 4 are independent of each other, and their movements do not affect each other because they use the same power source. Therefore, the speed relationship between the two depends on the gear ratio of the second bevel gear 15 and the first bevel gear 12. In this embodiment, the transmission ratio of the second bevel gear 15 to the first bevel gear 12 is 1:4, and the gear ratio of the second bevel gear 15 to the first bevel gear 12 is 4:1.

[0086] When retrieving wire 3, the take-up device... Figure 8 Position A in the middle moves to Figure 9 Position B in the middle; when the conductor 3 is released, the take-up device from Figure 9 Position B in the middle moves to Figure 8 Position A in the middle.

[0087] The protective cover 19 includes a motor cover 20 and a spur gear cover 21. The motor 13 is housed inside the motor cover 20, which protects the motor 13. The spur gear cover 21 has a ring-shaped structure, and a first spur gear 14 and a second spur gear 16 are housed inside the spur gear cover 21, which also protects the first spur gear 14 and the second spur gear 16. A limiting block 22 is also provided inside the motor cover 20 to fix the motor 13.

[0088] The first lead screw nut 18 is disposed inside the spur gear cover 21 and is connected to the spur gear cover 21. Rotating the first lead screw nut 18 clockwise or counterclockwise converts its circular motion into linear motion of the spur gear cover 21 on the second lead screw 17. The spur gear cover 21 is connected to or integrally formed with the motor cover 20. Screws are used to install the motor cover 20 and / or the spur gear cover 21 onto the lampshade 4. The spur gear cover 21 drives the motor cover 20 to move horizontally on the second lead screw 17, thereby causing the lampshade 4 to move along a first or third direction.

[0089] This embodiment also provides an air conditioner, including the winding device described in any one of embodiments 1-5.

[0090] like Figure 10 As shown, this embodiment also provides a method for designing cable take-up parameters. Based on the above-mentioned air conditioner, the method includes:

[0091] S1: Obtain the length L of the indoor unit evaporator of the air conditioner.

[0092] S2: Determine the number N of movable pulleys on the slider.

[0093] S3: Set the slide rail length to L / 2N.

[0094] S4: Set the transmission ratio of the first bevel gear and the second bevel gear to 4:1.

[0095] S5: Set the transmission ratio of the first spur gear and the second spur gear to 1:1; wherein the transmission ratio of the second bevel gear and the first spur gear is 1:1.

[0096] The length of the slide rail is directly proportional to the length L of the indoor unit evaporator and inversely proportional to the number of movable pulleys N. The transmission ratio of the first bevel gear 12 to the second bevel gear 15 is 2N:1, the transmission ratio of the first spur gear 14 to the second spur gear 16 is 1:1, and the transmission ratio of the second bevel gear 15 to the first spur gear 14 is 1:1. In this embodiment, taking a movable pulley count N of 2 as an example, the slide rail length is 1 / 4 of the length of the indoor unit evaporator, the tooth ratio of the first bevel gear 12 to the second bevel gear 15 is 1:4, the tooth ratio of the first spur gear 14 to the second spur gear 16 is 1:1, and the tooth ratio of the second bevel gear 15 to the first spur gear 14 is 1:1.

[0097] The length L of the indoor unit evaporator is the length of the winding device from... Figure 8 Point A moves along the first direction to Figure 9 The distance traveled at point B in the diagram.

[0098] In this embodiment, a second spur gear 16 is disposed near the first spur gear 14. The second spur gear 16 meshes with the first spur gear 14, and the rotation of the first spur gear 14 drives the second spur gear 16 to rotate. A first lead screw nut 18 is disposed inside the spur gear cover 21 and is connected to the spur gear cover 21. The first lead screw nut 18 rotates clockwise or counterclockwise, converting the circular motion of the first lead screw nut 18 into linear motion of the spur gear cover 21 on the second lead screw 17. The spur gear cover 21 drives the motor cover 20 to move horizontally on the second lead screw 17, thereby driving the lamp cover 4 to move in a first direction or a third direction.
