Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field, and in particular to a cleaning component and cleaning equipment. Background Technology
[0002] In cleaning equipment such as robotic vacuum cleaners, the mop disc rotates at a relatively low speed, while the motor driving the mop disc rotates at a relatively high speed. Therefore, related technologies often incorporate a multi-stage cylindrical gear reduction mechanism as a transmission mechanism between the motor and the mop disc to achieve speed reduction transmission from the motor to the mop disc. However, multi-stage cylindrical gear reduction mechanisms are often quite large, occupying a significant amount of internal installation space in the cleaning equipment, thus hindering the internal spatial layout of the cleaning device.

While achieving the same transmission ratio as the cylindrical gear reduction mechanism, the planetary gear mechanism has a smaller radial dimension. Therefore, this disclosure can reduce the size of the transmission mechanism to reduce the space occupied by the transmission mechanism inside the cleaning equipment.

[0036] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.
[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] This disclosure provides a cleaning component, such as... Figure 1 As shown, the cleaning assembly includes a drive mechanism 1, a transmission mechanism 2, and a mop tray 3. Combined with... Figure 2 As shown, the transmission mechanism 2 includes a first planetary gear mechanism 21 and a second planetary gear mechanism 22. The input end of the first planetary gear mechanism 21 is connected to the drive mechanism 1, the output end of the first planetary gear mechanism 21 is connected to the input end of the second planetary gear mechanism 22, and the output end of the second planetary gear mechanism 22 is connected to the wiping disc 3.
[0039] In this embodiment, a planetary gear mechanism is used as the transmission mechanism 2. Since the input and output ends of the planetary gear mechanism are coaxial, its overall structure is relatively compact. In contrast, the multiple gears of the cylindrical gear reduction mechanism are all parallel shafts, and its overall structure has a relatively large radial dimension. Therefore, while achieving the same transmission ratio as the cylindrical gear reduction mechanism, the planetary gear mechanism has a smaller radial dimension, which can reduce the size of the transmission mechanism 2 and thus reduce the space occupied by the transmission mechanism 2 in the internal installation space of the cleaning equipment.
[0040] Optionally, the transmission mechanism 2 may further include a third planetary gear mechanism, the input end of which is connected to the output end of the second planetary gear mechanism 22, and the output end of which is connected to the wiping disc 3. Similarly, the transmission mechanism 2 may include more stages of planetary gear mechanisms; this embodiment does not limit this.
[0041] In some embodiments, the drive mechanism 1 is a motor.
[0042] Among them, the motor is used as the drive mechanism 1. On the one hand, the motor has low noise during use, which can reduce the noise generated by the cleaning component during use. On the other hand, the motor has excellent speed regulation performance and controllability, so the cleaning component can be controlled relatively conveniently.
[0043] The drive mechanism 1 can be, for example, but not limited to, a brushless motor, a brushed motor, or a roller motor, and the embodiments disclosed herein do not impose any restrictions on this.
[0044] In some embodiments, the first planetary gear mechanism 21 and the second planetary gear mechanism 22 have the same structure.
[0045] Thus, when producing the first planetary gear mechanism 21 and the second planetary gear mechanism 22, the same parts are used for both, which can prevent the parts of the first planetary gear mechanism 21 and the second planetary gear mechanism 22 from being mixed up, thereby reducing the assembly difficulty of the cleaning components and improving the assembly efficiency of the cleaning components.
[0046] In some embodiments, such as Figure 2 As shown, the first planetary gear mechanism 21 includes a first sun gear 211, a first planet gear 212, a first planet carrier 213, and a fixed first gear ring 214. The first sun gear 211 is coaxial with the first planet carrier 213 and is connected to the drive mechanism 1. The first planet gear 212 is fixedly connected to the first planet carrier 213 and meshes with the first sun gear 211 and the first gear ring 214, respectively. The second planetary gear mechanism 22 includes a second sun gear 221, a second planet gear 222, a second planet carrier 223, and a fixed second gear ring 224. The second sun gear 221 is coaxial with the first planet carrier 213 and the second planet carrier 223 and is fixedly connected to the first planet carrier 213. The second planet gear 222 is fixedly connected to the second planet carrier 223 and meshes with the second sun gear 221 and the second gear ring 224, respectively. The second planet carrier 223 is connected to the wiping disc 3.
[0047] Combination Figure 3 , Figure 4 As shown, the first sun gear 211 is sleeved on the outside of the rotating shaft 1a of the drive mechanism 1, the first planet gear 212 is fixedly connected to the first planet carrier 213 through the first connecting shaft 215, the first planet carrier 213 has a first output shaft 213a on the side away from the first planet gear 212, the second sun gear 221 is sleeved on the outside of the first output shaft 213a, the second planet gear 222 is fixedly connected to the second planet carrier 223 through the second connecting shaft 225, the second planet carrier 223 has a second output shaft 223a on the side away from the second planet gear 222, and the second output shaft 223a is connected to the wiping disc 3 in a transmission connection.
[0048] When the shaft 1a of the drive mechanism 1 rotates, the first sun gear 211 rotates synchronously with the shaft 1a and drives the first planet gear 212 meshing with it to rotate around the fixed first gear ring 214. The first planet gear 212 drives the first planet carrier 213 to rotate, and the first planet carrier 213 outputs power through the first output shaft 213a. Thus, the transmission process of the first planetary gear mechanism 21 can be realized.
[0049] When the first planetary carrier 213 rotates, the second sun gear 221 rotates synchronously with the first output shaft 213a and drives the second planetary gear 222 meshing with it to rotate around the fixed second gear ring 224. The second planetary gear 222 drives the second planetary carrier 223 to rotate, and the second planetary carrier 223 outputs power through the second output shaft 223a. Thus, the transmission process of the second planetary gear mechanism 22 can be realized.
[0050] like Figure 4 As shown, the first planetary gear mechanism 21 includes three first planetary gears 212, which surround the sun gear. This allows the load on each individual first planetary gear 212 to be distributed, enabling the transmission of greater torque through the first planetary gear mechanism 21. Furthermore, the movement of the first planetary gears 212 will not be eccentric due to force, thereby improving the stability of the first planetary gear mechanism 21 and reducing the noise generated during its operation.
[0051] like Figure 4 As shown, the second planetary gear mechanism 22 includes three second planetary gears 222, which surround the sun gear. This disperses the load on each individual second planetary gear 222, allowing for the transmission of greater torque through the second planetary gear mechanism 22. Furthermore, the movement of the second planetary gears 222 will not be eccentric due to force, thereby improving the stability of the second planetary gear mechanism 22's operation and reducing the noise generated during its operation.
[0052] In some embodiments, the first sun gear 211 has 13-14 teeth.
[0053] Setting the number of teeth of the first sun gear 211 to 13 or 14 serves two purposes. First, it controls the number of teeth of the first gear ring 214 within a reasonable range to prevent the size of the first gear ring 214 from being too large, which would lead to an excessively large size of the transmission mechanism 2. Second, when the number of teeth of the first sun gear 211 is 13, the vibration order of the first planetary gear mechanism 21 is 1 and 13. When the number of teeth of the first sun gear 211 is 14, the vibration order of the first planetary gear mechanism 21 is 1, 2, 7, and 14. This avoids the first planetary gear mechanism 21 generating too many vibration orders, thus facilitating noise reduction of the first planetary gear.
[0054] In some embodiments, the second sun gear 221 has 13-14 teeth.
[0055] In this way, the number of teeth of the first gear ring 214 can be controlled within a reasonable range to prevent the size of the first gear ring 214 from being too large, which would result in the size of the transmission mechanism 2 being too large.
[0056] In some embodiments, the transmission ratio of the first planetary gear mechanism 21 is 6-11.
[0057] If the transmission ratio of the first planetary gear mechanism 21 is less than 6, the transmission ratio is too small, resulting in poor deceleration. If the transmission ratio is greater than 11, on the one hand, the size of the first planetary gear mechanism 21 may be too large, which may lead to the transmission mechanism 2 occupying too much space; on the other hand, it may lead to excessive deceleration, resulting in the final rotational speed of the mop disc 3 not meeting the usage requirements. Setting the transmission ratio of the first planetary gear mechanism 21 to 6-11 can ensure that the first planetary gear mechanism 21 has a good deceleration effect while avoiding the situation of the first planetary gear mechanism 21 being too large or excessive deceleration.
[0058] The transmission ratio of the first planetary gear mechanism 21 is mainly affected by the number of teeth of the first sun gear 211 and the first ring gear 214, and the transmission ratio of the first planetary gear mechanism 21 can be finely adjusted by adjusting the tooth profile of the first sun gear 211 and the first ring gear 214.
[0059] In some embodiments, the transmission ratio of the second planetary gear mechanism 22 is 6-11.
[0060] If the transmission ratio of the second planetary gear mechanism 22 is less than 6, the transmission ratio is too small, resulting in poor deceleration. If the transmission ratio is greater than 11, on the one hand, the size of the second planetary gear mechanism 22 may be too large, which may lead to the transmission mechanism 2 occupying too much space; on the other hand, it may lead to excessive deceleration, resulting in the final rotational speed of the mop disc 3 not meeting the usage requirements. Setting the transmission ratio of the second planetary gear mechanism 22 to 6-11 can ensure that the second planetary gear mechanism 22 has a good deceleration effect while avoiding the situation of the second planetary gear mechanism 22 being too large or excessively decelerating.
[0061] The transmission ratio of the second planetary gear mechanism 22 is mainly affected by the number of teeth of the second sun gear 221 and the second ring gear 224, and can be finely adjusted by adjusting the tooth profile of the second sun gear 221 and the second ring gear 224.
[0062] In some embodiments, such as Figure 3 As shown, the transmission mechanism 2 also includes a housing 24, which is fixedly connected to the outer shell of the drive mechanism 1 and accommodates at least a portion of the first planetary gear mechanism 21 and the second planetary gear mechanism 22.
[0063] The transmission mechanism 2 is fixedly connected to the housing of the drive mechanism 1 via the housing 24, thereby forming an integral structure with the drive mechanism 1. This enhances the stability and rigidity of the cleaning assembly. Furthermore, during the operation of the drive mechanism 1, it reduces the relative displacement between the transmission mechanism 2 and the drive mechanism 1 caused by vibration or external forces, thus maintaining the stable operation of the cleaning assembly.
[0064] Wherein, “the housing 24 accommodates at least a portion of the first planetary gear mechanism 21 and the second planetary gear mechanism 22” means that the housing 24 accommodates the entire first planetary gear mechanism 21 and at least a portion of the second planetary gear mechanism 22.
[0065] Optionally, the housing 24 is provided with grease to lubricate the movement of the first planetary gear mechanism 21 and the second planetary gear mechanism 22.
[0066] In some embodiments, such as Figure 3 As shown, the housing 24 includes a first cylindrical body 241 and a second cylindrical body 242. The opening of one of the first cylindrical body 241 and the second cylindrical body 242 abuts against the bottom wall of the other. The inner side wall of the first cylindrical body 241 is fixedly connected to the first toothed ring 214, and the inner side wall of the second cylindrical body 242 is fixedly connected to the second toothed ring 224.
[0067] Thus, by placing the first gear ring 214 and the second gear ring 224 inside the first cylinder 241 and the second cylinder 242 respectively, the first planetary gear mechanism 21 and the second planetary gear mechanism 22 can be separated by the bottom wall of one of the first cylinder 241 and the second cylinder 242, thereby reducing the possibility of interference between the two during operation.
[0068] Optionally, the first gear ring 214 is interference-fitted to the inner wall of the first cylinder 241, and the second gear ring 224 is interference-fitted to the inner wall of the second cylinder 242.
[0069] In some embodiments, the housing 24 further includes a first connecting plate 243, a connector 244, and a second connecting plate 245. The first connecting plate 243 is fixedly connected to the housing of the drive mechanism 1, and the first connecting plate 243 is fixedly connected to the second connecting plate 245 through the connector 244 passing through the first cylinder 241 and the second cylinder 242.
[0070] Thus, the second connecting plate 245 is fixedly connected to the first connecting plate 243 through the connector 244, thereby enabling the fixation of the first cylinder 241 and the second cylinder 242, and ensuring that the openings of the first cylinder 241 and the second cylinder 242 are in a basically closed state, so as to reduce the interference of the external environment on the transmission mechanism 2, thereby ensuring the transmission stability of the transmission mechanism 2.
[0071] Optionally, connector 244 is a long bolt.
[0072] Optionally, the first connecting plate 243 is fixedly connected to the housing of the drive mechanism 1 by a fastener 246, which may be a short bolt.
[0073] In some embodiments, the transmission mechanism 2 further includes a bevel gear mechanism 23, the input end of which is connected to the output end of the second planetary gear mechanism 22, and the output end of which is connected to the wiping disc 3.
[0074] Thus, after the first planetary gear mechanism 21 and the second planetary gear mechanism 22 reduce speed, the overall transmission ratio of the transmission mechanism 2 can be adjusted through the bevel gear mechanism 23 to ensure that the final output speed of the transmission mechanism 2 meets the usage requirements.
[0075] In some embodiments, the bevel gear mechanism 23 includes a first bevel gear 231 and a second bevel gear 232 that mesh with each other. The first bevel gear 231 is coaxial with and fixedly connected to the output end of the second planetary gear mechanism 22, and the second bevel gear 232 is coaxial with and fixedly connected to the wiping disc 3.
[0076] Thus, the first planetary gear mechanism 21, the second planetary gear mechanism 22, and the first bevel gear 231 are all coaxially arranged, while the second bevel gear 232 meshes with the first bevel gear 231. The angle between the output shafts of the second bevel gear 232 and the first bevel gear 231 is 90 degrees, which can change the direction of the torque output by the transmission mechanism 2. The second bevel gear 232 is coaxial with the wiping disc 3; therefore, the angle between the rotation axis of the wiping disc 3 and the output shaft of the first planetary gear mechanism 21 is 90 degrees. This prevents the problem of excessively large axial dimensions of both the transmission mechanism 2 and the wiping disc 3 in the first planetary gear mechanism 21 due to the coaxiality of the wiping disc 3 and the first planetary gear mechanism 21, thereby optimizing the spatial layout of the cleaning components within the cleaning equipment.
[0077] The table below provides specific parameters of the transmission mechanism of a cleaning component provided in an embodiment of this disclosure.
[0078] Table 1 Transmission Mechanism Parameter Table
[0079]
[0080] As shown in Table 1, in this example, the transmission ratios of the first planetary gear mechanism 21 and the second planetary gear mechanism 22 are both approximately 6.46, and the transmission ratio of the bevel gear mechanism 23 is approximately 1.077. Therefore, the final transmission ratio of the transmission mechanism 2 is approximately 6.64 * 6.64 * 1.077 ≈ 44.40. Thus, through this transmission mechanism 2, the 7000 rpm output speed of the drive mechanism 1 can be reduced to 157.66 rpm. Furthermore, it can be seen from the table that the first planetary gear mechanism 21, the second planetary gear mechanism 22, and the bevel gear mechanism 23 have fewer vibration orders and lower noise. Therefore, the transmission mechanism 2 provided in this embodiment has advantages such as a large transmission ratio, small size, and low noise.
[0081] Based on the same concept, this disclosure also provides a cleaning device, which includes the cleaning components mentioned above.
[0082] Alternatively, the cleaning equipment may be a robotic vacuum cleaner.
[0083] The cleaning equipment also includes a power module, a control module, a sensor module, a navigation and positioning module, a communication module, and an interaction module. The power module is mainly used to provide power and manage the overall power supply of the robot vacuum. The control module is responsible for overall control and coordination of the work of each module. The sensor module is used to detect obstacles, measure distances, and prevent falls. The navigation and positioning module is used to build maps, plan cleaning paths, and locate its own position. The communication module allows users to remotely control the robot vacuum, view the cleaning status, and receive reminders. The interaction module provides an interface for interaction between the user and the robot vacuum.
