[0024] The inventors discovered that existing automatic pool cleaning devices are limited by size, weight, and production costs, and their battery capacity is relatively low. Battery life is a crucial performance factor for any product. Therefore, a vital research question is how to minimize the load on the battery from the drive mechanism and roller brush, given a fixed battery capacity, in order to improve battery life.

[0025] To remedy the defect of the existing automatic pool cleaning device, which has a relatively short battery life and is difficult to keep operating underwater for extended periods, the present utility model proposes a drive mechanism, a drive mechanism for an automatic pool cleaning device, and an automatic pool cleaning device.

[0026] Fig. Figures 1A-1B schematically show the appearance of an automatic pool cleaning device 100 according to an embodiment of the present disclosure. The automatic pool cleaning device 100 can be used as needed to perform cleaning on the floor, walls, and in and on the water of the pool (e.g., swimming pool), such as removing debris in the water, on the water bottom and on the water surface, and removing dirt from the bottom and walls of the pool.

[0028] Fig. Figures 2-3 schematically show the structure of the gear mechanism of the automatic basin cleaning device according to an embodiment of the present disclosure, which is exposed after removal of the side end cover of the drive mechanism.

[0029] As in Fig. As shown in Figures 2-3, the driving mechanism can comprise a driving wheel 20, a driven wheel 21 and a crawler chain 23 connecting the driving wheel 20 and the driven wheel 21, wherein the driving wheel 20 can drive the driven wheel 21 via the crawler chain 23.

[0030] As in Fig. As shown in 2-3, the first gear mechanism can include a drive power transmission gear 10.

[0031] As in Fig. As shown further in 2-3, the first gear mechanism may also include: a first gear 11 and a second gear 30, wherein the second gear 30 is connected to the rotating shaft of the first cleaning component (e.g. the one in Fig. 1A shown first cleaning component 120) is connected; the second gear 30 engages in the first gear 11, and the first gear 11 engages in the drive transmission gear 10, and the drive transmission gear 10 drives the first cleaning component to rotation via the first gear 11 and the second gear 30.

[0032] As in Fig. As shown in Figures 2-3, wheel teeth are provided on the inner circumferential side of the wheel rim of the driving wheel 20 and wheel teeth are provided on the outer circumferential side of the wheel rim of the power transmission wheel 10, and the power transmission wheel 10 engages with the driving wheel 20.

[0033] Optional, as in Fig. As shown in 2-3, in the automatic basin cleaning device described above, the wheel diameter of the driving wheel 20 is larger than the wheel diameter of the drive power transmission gear 10.

[0034] Optional are, as in Fig. As shown in Figures 2-3, in the automatic basin cleaning device described above, the first gear 11, the second gear 12 and the drive power transmission gear 10 are arranged such that they are located in the area of ​​the wheel rim of the driving wheel 20.

[0035] Optionally, the automatic basin cleaning device described above has a first gear ratio between the driving wheel and the drive power transmission gear; there is a second gear ratio between the first gear wheel and the drive power transmission gear, the second gear ratio being different from the first gear ratio.

[0036] Optionally, the automatic basin cleaning device described above also includes a second gear mechanism.

[0037] As in Fig. As shown in 2-3, the second gear mechanism comprises a third gear 22 and a fourth gear 12 which engages with the third gear 22, the third gear 22 and the driven wheel 21 rotating synchronously.

[0038] Optionally, the automatic pool cleaning device described above includes, as in Fig. 2-3 further shown, the second gear mechanism is a fifth gear 31 which engages with the fourth gear 12.

[0039] Optionally, the at least one cleaning component in the automatic pool cleaning device described above also includes a second cleaning component, such as the one described in Fig. Figure 1B shows the second cleaning component 130, and the fifth gear 31 is connected to the rotating shaft of the second cleaning component. The driven gear 21 thus drives the second cleaning component to rotation via the second gear mechanism.

[0040] Optionally, the first cleaning component and the second cleaning component include roller brushes in the automatic basin cleaning device described above.

[0041] Optionally, the automatic basin cleaning device in the automatic basin cleaning device described above also includes a drive mechanism to provide the drive force to the drive force transmission gear.

[0042] Optionally, the drive mechanism includes a motor in the automatic pool cleaning device described above.

[0043] In one embodiment, a drive mechanism comprises a driving element and two first driven elements, wherein the driving element outputs a rotary driving force, the driving element has an output end, the output end drives each of the two first driven elements, and the two first driven elements rotate under the drive of the output end. Thus, the one driving element can drive two first driven elements to rotation via its output end, and compared to a gear mode in which two driving elements each drive two first driven elements, the drive mode in the present embodiment is more energy-efficient, so that the motor shaft in the drive mechanism is subjected to a balanced force while achieving maximum gear efficiency.The drive mechanism of the present embodiment is applied to an automatic pool cleaning device, and the two first driven elements are the drive mechanism and the roller brush of the automatic pool cleaning device, respectively. This allows not only the movement of the automatic pool cleaning device and the rolling of the roller brush to complete the cleaning of the pool floor and walls, but also reduces energy consumption. Despite a relatively small battery capacity in the automatic pool cleaning device, a relatively good battery life and extended underwater operation can be maintained, thus improving the user experience.

[0044] In other embodiments, the drive mechanism can include three or even more first driven elements, depending on the various application scenarios, and the single driving element can drive three or even more first driven elements to rotate via its output end, further reducing energy consumption. Different gear ratios between the output end and its various first driven elements can be designed according to actual requirements.

[0045] In one embodiment, the driving element comprises a drive gear 10 and a drive source (e.g., a motor), wherein the drive source drives the drive gear 10 to rotate along its axial direction, and each first driven element engages in drive engagement with the drive gear 10. In another embodiment, each first driven element is arranged on and engages in different areas along the circumference of the drive gear 10's teeth, and each first driven element engages in drive engagement with the teeth of different areas, thereby avoiding mutual interference between different first driven elements.It is understood that one first driven element can be a gear with an internal ring of teeth, and the drive gear 10 engages in its internal ring of teeth; the other first driven element can be a gear with an external ring of teeth, and the drive gear 10 engages in its external ring of teeth. In other embodiments, each first driven element engages the gear teeth on the drive gear 10 in different regions along its axial direction, which can also prevent mutual interference between a plurality of first driven elements, thus ensuring that a plurality of first driven elements can rotate freely under the drive of the drive gear 10.At this point, the number of teeth or the diameter of the gear teeth on the drive transmission gear 10 can be adjusted in different areas along its axial direction as required.

[0046] In one embodiment, the output end comprises individual gear rings on the drive gear 10, which are arranged offset along its axial direction, and each first driven element engages in drive engagement with one of the individual gear rings. Different individual gear rings drive different first driven elements to rotation without interfering with each other. By changing the number of teeth and the diameter of the individual gear rings, the transmission ratio of the drive gear 10 to different first driven elements can be more easily changed to meet different transmission requirements.

[0047] In one embodiment, the drive mechanism further comprises at least one second driven element, wherein at least the second driven element is geared to the first driven element, such that the single driving element can directly drive at least two first driven elements and indirectly drive at least one second driven element to rotation, thereby further reducing energy consumption. In addition, the drive mechanism comprises a pair of second driven elements, wherein one of the second driven elements is geared to the first driven element, and the pair of second driven elements is geared to each other. Thus, the single driving element can directly drive at least two first driven elements and indirectly drive two second driven elements to rotation, resulting in improved energy savings.

[0048] In one embodiment, the drive mechanism further comprises a gear wheel arranged between the first driven element and the driving element, which can change the direction of rotation of the first driven element as well as the gear ratio between the driving element and the first driven element, and can be adapted to a wider range of application scenarios. In addition, a gear wheel is also arranged between a pair of second driven elements and is used to change the direction of rotation of the second driven elements as well as the gear ratio between the pair of second driven elements, thereby further improving the applicable scenarios of the drive mechanism and facilitating its application and widespread use.

[0049] In one embodiment as in Fig. As shown in Figures 2-3, a drive mechanism for an automatic basin cleaning device comprises a drive source (e.g., a motor, not shown), a drive transmission gear 10, a driving gear 20, and a second gear 30. The drive source drives the drive transmission gear 10 to rotate along its axial direction. The drive transmission gear 10 is motiveally connected to both the driving gear 20 and the second gear 30. The driving gear 20 and the second gear 30 rotate under the drive of the drive transmission gear 10. The driving gear 20 can drive the automatic basin cleaning device to move. The second gear 30 can drive the at least one cleaning component to rotate, so that the drive transmission gear 10 can synchronously drive the automatic basin cleaning device to move and the at least one cleaning component to rotate.In comparison to a drive mechanism that requires two drive sources, one to move the automatic pool cleaning device and the other to rotate the at least one cleaning component, the drive mechanism of the automatic pool cleaning device of the present embodiment is more energy-efficient and can still maintain a relatively good battery life in the case of a relatively small battery capacity of the automatic pool cleaning device, maintain underwater operation for a long period of time and improve the user experience, which corresponds to the synchronous drive of the second gear 30 by driving the driving wheel 20 or the synchronous drive of the driving wheel 20 by driving the second gear 30, so that the force on the shaft of the drive source is balanced and at the same time maximum transmission efficiency is achieved.

[0050] In one embodiment, one side of the drive force transmission gear 10 is connected to the driving wheel 20, and the other side is connected to the second gear 30, thereby avoiding mutual interference between the driving wheel 20 and the second gear 30.

[0051] In one embodiment, gears of the drive power transmission gear 10 are connected at different positions along its axial direction to the driving wheel 20 and the cleaning roller brush, i.e.The length of the drive gear 10 along its axial direction is longer than the axial length of the driving gear 20 and the second gear 30, and the driving gear 20 and the second gear 30 are nested in the axial direction of the drive gear 10, so that mutual interference between the driving gear 20 and the second gear 30 can be avoided, the distance between the driving gear 20 and the second gear 30 is increased, and the difficulty of installation is reduced, which is conducive to separate maintenance or separate replacement of the driving gear 20 or the second gear 30 at a later time.

[0052] For example, the drive power transmission gear 10 can comprise a double gear structure, as in Fig. 4A shown.

[0053] In one embodiment, two individual gear rings are arranged offset on the drive gear 10 along its axial direction, and the driving gear 20 and the second gear 30 each engage with one of the individual gear rings. The different individual gear rings drive the driving gear 20 and the second gear 30 respectively, and the gear ratios of the two do not affect each other. By changing the number of teeth, the diameter, etc., of the different individual gear rings, the gear ratio of the drive gear 10 to the driving gear 20 and to the second gear 30 can be more easily changed to meet different gear requirements.

[0054] For example, as in Fig. As shown in Figure 4B, the driving wheel 20 is provided with wheel teeth along the outside of the circumference of its axle opening.

[0055] Fig. Figure 5 shows the engagement structure of the drive power transmission gear 10, which uses a double gear structure, with the driving gear 20 and the first transmission gear 11. As in Fig. As shown in Figure 5, the driving wheel 20 is provided with gear teeth along the outside of the circumference of its shaft bore, and the drive power transmission gear 10 is a double gear structure, wherein the first gear of the double gear structure engages with the gear teeth provided on the outside of the circumference of the shaft bore of the driving wheel 20, and the second gear of the double gear structure engages with the first gear 11. It should be noted that, although in Fig. Figure 5 shows that the first gear 11 engages with the second gear 30 via an intermediate gear 15, but it is also possible to do without the intermediate gear 15 and to allow the first gear 11 to engage directly with the second gear 30.

[0056] In one embodiment, an inner surface of the driving wheel 20 is provided with a first internal toothed ring that engages with the drive transmission gear 10, and the second gear 30 engages with the drive transmission gear 10, so that the drive transmission gear 10 can drive the driving wheel 20 to rotate in the same direction, and at the same time the drive transmission gear 10 can also drive the second gear 30 to rotate in the opposite direction, so that one drive source can synchronously drive the automatic basin cleaning device to move and the at least one cleaning component to rotate, thereby reducing energy consumption, extending the battery life of the automatic basin cleaning device and improving the user experience.Furthermore, the drive mechanism of the automatic basin cleaning device in the present embodiment has a simpler structure, which simplifies the transmission process and reduces production costs; the drive mechanism is integrated, thus eliminating the need for two independent drive sources and drive force transmission gears 10, which makes the overall structure more compact and takes up less space inside the automatic basin cleaning device, so that more other functional modules can be installed inside the automatic basin cleaning device.

[0057] In one embodiment, the gear ratio of the drive gear 10 to the driving gear 20 is greater than the gear ratio of the drive gear 10 to the second gear 30. The gear ratio refers to the ratio between the rotational speed of the input gear and that of the output gear; that is, the ratio between the rotational speed of the drive gear 10 and that of the driving gear 20 is greater than the ratio between the rotational speed of the drive gear 10 and that of the second gear 30. In other words, under the gear ratio...In the transmission of the drive gear 10, the rotational speed of the second gear 30 is greater than that of the driving gear 20, so that when the driving gear 20 drives the automatic basin cleaning device to move at a speed appropriate to the requirements, a faster rotational speed of the second gear 30 can drive the at least one cleaning component to repeatedly stir the dirt on the bottom and walls of the basin until the dirt is loosened, thereby improving the cleaning power and cleaning efficiency of the at least one cleaning component.

[0058] In one embodiment as in Fig. As shown in Figures 2-3, the drive mechanism of the automatic basin cleaning device further comprises a first gear 11, and the drive force transmission gear 10, the first gear 11 and the second gear 30 engage successively with each other.The first gear 11 can change the rolling direction of the second gear 30, so that the second gear 30 rotates in the same direction as the driving wheel 20, that is, the direction of rotation of the at least one cleaning component is the same as the direction of movement of the automatic basin cleaning device, so that the dirt stirred up by the at least one cleaning component can be pushed by the at least one cleaning component to the water inlet in the middle bottom of the automatic basin cleaning device, so that the water inlet can draw in the dirt and collect the dirt through a waste filter box communicating with the water inlet, thereby improving the cleaning efficiency of the automatic basin cleaning device.In addition, the first gear 11 can also change the gear ratio between the drive transmission gear 10 and the second gear 30, thus changing the speed of at least one cleaning component, so that different speeds of the roller brush can be selected for swimming pools with different types and structural surfaces of dirt, resulting in a better cleaning effect and higher cleaning efficiency.

[0059] In one embodiment, the drive mechanism of the automatic basin cleaning device comprises a plurality of first gears 11, wherein the plurality of first gears 11 are adjacent in pairs, the adjacent two first gears 11 mesh with each other, and the first and last two first gears 11 each mesh with the drive gear 10 and the second gear 30, respectively. The gear ratio can be changed independently by each first gear 11, and the plurality of first gears 11 allows the gear ratio to be changed over a wider range, thus providing greater flexibility and enabling the fulfillment of more diverse cleaning requirements.

[0060] In one embodiment, the number of first gear teeth 11 is even, so that the direction of rotation of the second gear tooth 30 is opposite to that of the drive force transmission gear 10, that is, the direction of rotation of the at least one cleaning component is opposite to the direction of movement of the automatic pool cleaning device, and on the one hand, in this arrangement, the reaction force caused by the forward movement of the robot can be used to push away the dirt that is more easily detached from the bottom and walls of the pool, thereby reducing the work intensity and energy consumption of the at least one cleaning component itself, and on the other hand, the at least one cleaning component, after it has stirred up the debris on the bottom and walls of the pool, can push it away, thereby reducing its obstruction of the movement of the automatic pool cleaning device.

[0061] In one embodiment, the drive mechanism of the automatic pool cleaning device further comprises a crawler chain 23 and a driven wheel 21, wherein the crawler chain 23 is tensioned between the driving wheel 20 and the driven wheel 21, so that the driven wheel 21 can rotate synchronously under drive by the driving wheel 20, and the automatic pool cleaning device is driven to move with the driving wheel 20.

[0062] In one embodiment, the drive mechanism of the automatic basin cleaning device further comprises a fifth gear 31. The driven gear 21 is drivenly connected to the fifth gear 31. The drive force transmission gear 10 drives the fifth gear 31 to rotate across the distance between the driving gear 20 and the driven gear 21. The fifth gear 31 drives the second cleaning component (e.g., the roller brush) to rotate, thus enabling the automatic basin cleaning device to achieve improved energy-saving and cleaning performance. Specifically, the driven gear 21 can be coaxially and rigidly connected to the third gear 22, and the fifth gear 31 engages with the third gear 22.The fifth gear 31 is used to drive the second roller brush into rotation, so that the driven wheel 21 drives the third gear 22 into synchronous rotation, and then the third gear 22 drives the fifth gear 31 into rotation, and the fifth gear 31 drives the second roller brush into rotation, causing the debris on the bottom and walls of the swimming pool to fall off, thus further improving the cleaning capability and efficiency of the automatic pool cleaning device. The driven wheel 21 and the driving wheel 20 together drive the automatic pool cleaning device into motion, while the first cleaning component and the second cleaning component work together to clean the dirt on the bottom and walls of the swimming pool.The movement of the four components is driven synchronously by a single power source, which further reduces energy consumption, ensures the battery life of the automatic pool cleaning device, and improves ease of use.

[0063] In one embodiment as in Fig.As shown in Figures 2-3, the drive mechanism further comprises a fourth gear 12, wherein the third gear 22, the fourth gear 12, and the fifth gear 31 mesh sequentially. The fourth gear 12 can also serve to change the direction of rotation of the fifth gear 31, so that the direction of rotation of the second roller brush is the same as the direction of travel of the driven wheel 21, allowing the second roller brush, after stirring up the debris on the floor and walls of the basin, to push it away, thereby reducing its obstruction to the movement of the automatic basin cleaning device.In addition, the fourth gear 12 can also change the gear ratio between the third gear 22 and the fifth gear 31, thereby changing the speed of the second roller brush to adapt it to the different types of dirt in the swimming pool and to improve its cleaning effect.

[0064] In other embodiments, it is also possible to provide a plurality of fourth gears 12, wherein the plurality of fourth gears 12 are arranged in adjacent pairs, and the adjacent two fourth gears 12 mesh with each other, and the first and last two fourth gears 12 each mesh with the third gear 22 and the fifth gear 31, respectively. The plurality of fourth gears 12 allows the gear ratio between the third gear and the fifth gear 31 to be changed more flexibly to meet a wider range of cleaning requirements. If the number of fourth gears 12 is odd, the direction of rotation of the second roller brush is the same as the direction of travel of the driven wheel 21. After stirring up the debris on the bottom and walls of the basin, the second roller brush can push it away.If the number of fourth gears 12 is even, the direction of rotation of the second roller brush is opposite to the direction of movement of the driven wheel 21, so that the debris stirred up by the second roller brush can be pushed by the second roller brush to the water inlet in the middle bottom of the automatic pool cleaning device, so that the water inlet can suck up the dirt and collect the dirt through a debris filter box communicating with the water inlet, thereby improving the cleaning efficiency of the automatic pool cleaning device.

[0065] In one embodiment, the drive mechanism of the automatic pool cleaning device further comprises a driven wheel, a fifth gear, and a tracked chain, the tracked chain being tensioned between the driving wheel and the driven wheel so that the driven wheel can rotate synchronously under the drive of the driving wheel, and the automatic pool cleaning device is driven to move synchronously with the driving wheel. A second inner ring gear is provided on the inside of the driven wheel, and the fifth gear engages with this second inner ring gear. The fifth gear is used to drive the second roller brush to rotation.The driven wheel can, via its second inner gear ring, drive the fifth gear wheel for synchronous rotation. The fifth gear wheel then drives the second roller brush wheel for rotation, thereby agitating debris on the bottom and walls of the swimming pool, thus further improving the cleaning capability and efficiency of the automatic pool cleaning device. In the present embodiment, the third gear wheel 22 can be omitted, resulting in a simpler overall structure, lower costs, a more compact design, and a smaller footprint. In other embodiments, the fifth gear wheel can also mesh with the second inner gear ring via sixth gear wheels (not shown) for transmission, and the number of sixth gear wheels can be either odd or even.In other words, the fifth gear that drives the roller brush and the second inner ring gear of the driven wheel can mesh with each other via at least one transition gear.

[0066] In one embodiment, an outer toothed ring is provided on the outer circumference of both the driving wheel 20 and the driven wheel 21, and the inner surface of the crawler track 23 is provided with a plurality of first belt teeth adapted to the outer toothed ring. When the crawler track 23 is tensioned on the driving wheel 20 and the driven wheel 21, the first belt teeth engage with the outer toothed rings on the outer circumference of the driving wheel 20 and the driven wheel 21, so that the belt can be tightly tensioned on the driving wheel 20 and the driven wheel 21, enabling the driving wheel 20 to drive the driven wheel 21 more reliably to synchronous rotation, thus ensuring that the swimming pool cleaning machine can move stably.

[0067] In one embodiment, the outer surface of the crawler track 23 is further provided with a plurality of second belt teeth 24, which enable the crawler track 23 to grip the floor and walls of the swimming pool more securely, thereby improving the grip and wall-climbing ability of the automatic pool cleaning device and further ensuring that the swimming pool cleaning machine can move stably.

[0068] In one embodiment, the automatic basin cleaning device comprises a pair of drive mechanisms, each arranged on either side of the base body. Each pair of drive mechanisms drives a pair of drive gears 10 and a pair of driven gears 21 to rotation. If the pair of drive gears 10 move at the same speed and in the same direction, the automatic basin cleaning device can be moved forward or backward. If the pair of drive gears 10 move at different speeds or in opposite directions, the automatic basin cleaning device can be reversed.

[0069] In one embodiment, the automatic basin cleaning device further comprises two roller brushes, each being a first roller brush and a second roller brush. The drive gear 10 drives the second gear 30 to rotate, and the second gear 30 drives the first roller brush to rotate. The drive gear 10 drives the fifth gear 31 to rotate via the distance between the driving gear 20 and the driven gear 21, and the fifth gear 31 drives the second roller brush to rotate. That is, the drive of the first roller brush is not subject to the driving gear, so that the drive force of the first roller brush is transmitted more directly and easily, thereby reducing the power conversion between multiple mechanisms and improving transmission efficiency.
