Swimming pool cleaning devices are a type of cleaning device developed to meet the needs of swimming pool cleaning. They can repeatedly clean the pool bottom and pool walls and filter the water in the pool.

[0003] The swimming pool cleaning device has a built-in power system. During the operation of the swimming pool cleaning device, the stored electric energy is used to power the swimming pool cleaning device and the roller brush respectively, so that the swimming pool cleaning device can move on the bottom and wall of the swimming pool, and the roller brush can roll at the same time, so as to clean the pollutants on the bottom and wall of the swimming pool.

[0004] However, the existing pool cleaning devices have relatively small battery capacities due to the limitations of volume, weight and production costs. Battery life is a performance that a product must pursue, so it is necessary to study how to minimize the load of the mobile mechanism and roller brush on the battery under the premise of a given battery capacity, so as to improve battery life. Utility Model Content

[0005] In order to solve the defects of the existing swimming pool cleaning device, that is, the endurance is relatively poor and it is difficult to maintain long-term underwater work, the utility model provides a driving mechanism of the swimming pool cleaning device and the swimming pool cleaning device.

[0006] The technical solution adopted by the utility model is a driving mechanism, comprising: an active member, the active member having an output end for outputting rotational power; at least two first driven members, each of which is drivingly connected to the output end and driven to rotate.

[0007] In one embodiment, the active member includes an output gear and a driving source that drives the output gear to rotate along its axial direction, the output end is gear teeth in different circumferential and / or axial regions on the output gear, and each of the first driven members is respectively meshed with gear teeth in different regions.

[0008] In one embodiment, the active member includes an output gear and a driving source that drives the output gear to rotate along its axial direction, the output end is a gear ring unit that is staggered along its axial direction on the output gear, and each of the first driven members is respectively in driving engagement with one of the gear ring units.

[0009] In one embodiment, the output gear has different transmission ratios to the plurality of first driven members.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model.

[0026] In one embodiment, a driving mechanism includes an active member and two first driven members. The active member outputs rotational power. The active member has an output end. The output ends drive and connect the two first driven members respectively. The two first driven members rotate under the drive of the output end. Thus, one active member can drive the two first driven members to rotate through its output end. Compared with the transmission method in which two active members drive the two first driven members respectively, the driving method in this embodiment is more energy-saving, so that the force of the motor shaft in the driving mechanism is balanced while also achieving the maximum transmission efficiency. The driving mechanism in this embodiment is applied to a swimming pool cleaning device. The two first driven members are respectively the moving mechanism and the roller brush of the swimming pool cleaning device, so that the movement of the swimming pool cleaning device and the rolling of the roller brush can be realized, and the bottom and wall of the swimming pool can be cleaned, and energy consumption can be saved. When the battery capacity of the swimming pool cleaning device is relatively small, it can still maintain a better endurance and maintain long-term underwater work, thereby improving the user experience.

[0027] In other embodiments, depending on the application scenario, the driving mechanism may include three or more first driven members, and one active member may drive three or more first driven members to rotate through its output end, further saving energy consumption. Different transmission ratios may be designed between the output end and its different first driven members according to actual needs.

[0028] In one embodiment, the active member includes an output gear 10 and a driving source, the driving source drives the output gear 10 to rotate along its axial direction, and each first follower is respectively in transmission meshing with the output gear 10. In one embodiment, each first follower is correspondingly arranged at the gear teeth of different regions along its circumference on the output gear 10 and meshed therewith, and each first follower is respectively in transmission meshing with the gear teeth of different regions, which can avoid mutual interference between different first followers. It can be understood that one first follower can be a gear with an inner gear ring, and the output gear 10 is meshed with its inner gear ring; another first follower is a gear with an outer gear ring, and the output gear 10 is meshed with its outer gear ring. In other embodiments, each first follower is correspondingly meshed with the gear teeth of different regions along its axial direction on the output gear 10, which can also play the effect of avoiding mutual interference between multiple first followers, ensuring that multiple first followers can rotate freely under the drive of the output gear 10, and at this time, the number of teeth or diameter of the gear teeth of different regions along its axial direction on the output gear 10 can be set as needed.

[0029] In one embodiment, the output end is a gear ring monomer arranged staggered along the axial direction of the output gear 10, and each first driven member is respectively in transmission meshing with one of the gear ring monomers. Different gear ring monomers drive different first driven members to rotate without interfering with each other. By changing the number of teeth and diameter of different gear ring monomers, the transmission ratio of the output gear 10 to different first driven members can be more conveniently changed to meet different transmission requirements.

[0030] In one embodiment, the driving mechanism further includes a second follower, which is transmission-connected to a first follower, so that one active member can directly drive at least two first followers, and indirectly drive one second follower to rotate, further saving energy consumption. Further, the driving mechanism includes a pair of second followers, one second follower is transmission-connected to a first follower, and the pair of second followers are transmission-connected to each other. Thus, one active member can directly drive at least two first followers, and indirectly drive two second followers to rotate, with better energy saving effect.

[0031] In one embodiment, the driving mechanism further includes a transition gear, which is disposed between the first driven member and the driving member. The transition gear can change the rotation direction of the first driven member and the transmission ratio between the driving member and the first driven member, and can be applied to more application scenarios. Furthermore, the transition gear is also disposed between a pair of second driven members, and is used to change the rotation direction of the second driven member and the transmission ratio between the pair of second driven members, further improving the applicable scenarios of the driving mechanism and facilitating promotion and application.

[0032] In one embodiment, Figure 1-2 As shown, a driving mechanism of a swimming pool cleaning device includes a driving source, an output gear 10, a walking wheel 20 and a first roller brush gear 30. The driving source drives the output gear 10 to rotate along its axial direction. The output gear 10 is driven and connected to the walking wheel 20 and the first roller brush gear 30 respectively. The walking wheel 20 and the first roller brush gear 30 rotate under the drive of the output gear 10. The walking wheel 20 can drive the swimming pool cleaning device to move, and the first roller brush gear 30 can drive the first roller brush to rotate, so that one output gear 10 can synchronously drive the swimming pool cleaning device to move and the first roller brush to rotate. Compared with a driving mechanism that requires two driving sources to respectively drive the swimming pool cleaning device to move and the first roller brush to rotate, the driving mechanism of the swimming pool cleaning device of this embodiment is more energy-saving. When the battery capacity of the swimming pool cleaning device is relatively small, it can still maintain a better endurance and maintain long-term underwater work, thereby improving user experience. It is equivalent to synchronously driving the first roller brush gear 30 by driving the walking wheel 20, or synchronously driving the walking wheel 20 by driving the first roller brush gear 30. The shaft force of the driving source is balanced and the maximum transmission effect is also achieved.

[0033] In one embodiment, one side of the output gear 10 is drivingly connected to the travel wheel 20 , and the other side is drivingly connected to the first roller brush gear 30 , thereby avoiding mutual interference between the travel wheel 20 and the first roller brush gear 30 .

[0034] In one embodiment, gears at different axial positions of the output gear 10 respectively drive and connect the travel wheel 20 and the cleaning roller brush, that is, the axial length of the output gear 10 is longer than the axial length of the travel wheel 20 and the first roller brush gear 30, and the travel wheel 20 and the first roller brush gear 30 are staggered in the axial direction of the output gear 10, thereby avoiding mutual interference between the travel wheel 20 and the first roller brush gear 30, increasing the distance between the travel wheel 20 and the first roller brush gear 30, reducing the difficulty of installation, and facilitating the subsequent separate maintenance or replacement of the travel wheel 20 or the first roller brush gear 30.

[0035] In one embodiment, two gear ring units are staggered along the axial direction of the output gear 10, and the travel wheel 20 and the first roller brush gear 30 are respectively engaged with one of the gear ring units, and different gear ring units drive the travel wheel 20 and the first roller brush gear 30 respectively, and the transmission of the two does not affect each other. By changing the number of teeth, diameter, etc. of different gear ring units, the transmission ratio of the output gear 10 to the travel wheel 20 and the first roller brush gear 30 can be more conveniently changed to meet different transmission requirements.

[0036] In one embodiment, a first inner gear ring meshing with the output gear 10 is provided on the inner side of the traveling wheel 20, and the first roller brush gear 30 meshes with the output gear 10, so that the output gear 10 can drive the traveling wheel 20 to rotate in the same direction. At the same time, the output gear 10 can also drive the first roller brush gear 30 to rotate in the opposite direction, so that one driving source can synchronously drive the swimming pool cleaning device to move and the first roller brush to rotate, saving energy consumption, improving the endurance of the swimming pool cleaning device, and improving the user experience. In addition, the driving mechanism structure of the swimming pool cleaning device of this embodiment is more concise, the transmission method is simplified, and the production cost is reduced; the driving mechanism is integrated, and there is no need for two independent driving sources and output gears 10, the overall structure is more compact, and the internal space of the swimming pool cleaning device is smaller, and more other functional modules can be installed inside the swimming pool cleaning device.

[0037] In one embodiment, the transmission ratio of the output gear 10 to the walking wheel 20 is greater than the transmission ratio of the output gear 10 to the first roller brush gear 30. The transmission ratio refers to the ratio of the rotational speed of the input gear to the rotational speed of the output gear 10, that is, the ratio of the rotational speed of the output gear 10 to the rotational speed of the walking wheel 20 is greater than the ratio of the rotational speed of the output gear 10 to the rotational speed of the first roller brush gear 30. That is, under the transmission of the output gear 10, the rotational speed of the first roller brush gear 30 is greater than that of the walking wheel 20. Therefore, when the walking wheel 20 drives the swimming pool cleaning device to move at a required moving speed, the faster rotational speed of the first roller brush gear 30 can drive the first roller brush to repeatedly stir the dirt on the bottom and wall of the pool until the dirt falls off, thereby improving the cleaning force and cleaning efficiency of the first roller brush.

[0038] In one embodiment, the driving mechanism of the swimming pool cleaning device further includes a first transition gear 11, and the output gear 10, the first transition gear 11 and the first roller brush gear 30 are meshed in sequence. A first transition gear 11 can change the rolling direction of the first roller brush gear 30, so that the first roller brush gear 30 rotates in the same direction as the walking wheel 20, that is, the rotation direction of the first roller brush is the same as the forward direction of the swimming pool cleaning device, so that the dirt stirred and detached by the first roller brush can be pushed to the water inlet in the middle of the lower part of the swimming pool cleaning device by the first roller brush, so that the water inlet sucks the dirt and collects the dirt through the garbage filter box connected to the water inlet, thereby improving the cleaning efficiency of the swimming pool cleaning device. In addition, the first transition gear 11 can also change the transmission ratio between the output gear 10 and the first roller brush gear 30, thereby changing the rotation speed of the first roller brush. For swimming pools with different dirt types and structural surfaces, different roller brush rotation speeds can be selected in a targeted manner, and the cleaning effect is better and the cleaning efficiency is higher.

[0039] In one embodiment, the driving mechanism of the swimming pool cleaning device includes a plurality of first transition gears 11, wherein the plurality of first transition gears 11 are adjacent to each other, and two adjacent first transition gears 11 are meshed with each other, and the first and last first transition gears 11 are respectively meshed with the output gear 10 and the first roller brush gear 30. Each first transition gear 11 can independently change the transmission ratio, and the plurality of first transition gears 11 can change the transmission ratio in a wider range, with higher flexibility, and can meet more different cleaning needs.

[0040] In one embodiment, the number of first transition gears 11 is an even number. At this time, the rotation direction of the first roller brush gear 30 is opposite to that of the output gear 10, that is, the rotation direction of the first roller brush is opposite to the forward direction of the swimming pool cleaning device. On the one hand, this setting can use the reaction force brought by the robot's forward movement to help push the dirt, and the dirt is easier to peel off from the bottom and wall of the pool, thereby reducing the working intensity and energy consumption of the first roller brush itself. On the other hand, the first roller brush can push away the garbage on the bottom and wall of the pool after stirring it down, thereby reducing its hindrance to the movement of the swimming pool cleaning device.

[0041] In one embodiment, the driving mechanism of the swimming pool cleaning device further includes a track 23 and a driven wheel 21, wherein the track 23 is tensioned on the running wheel 20 and the driven wheel 21, so that the driven wheel 21 can rotate synchronously with the running wheel 20 and synchronously drive the swimming pool cleaning device to move with the running wheel 20.

[0042] In one embodiment, the driving mechanism of the swimming pool cleaning device further includes a second roller brush gear 31, the driven wheel 21 is driven to connect to the second roller brush gear 31, the output gear 10 drives the second roller brush gear 31 to rotate through the spacing between the running wheel 20 and the driven wheel 21, and the second roller brush gear 31 drives the second roller brush to rotate, so that the energy saving effect and cleaning effect of the swimming pool cleaning device are better. Specifically, the driven wheel 21 is coaxially fixedly connected to the concentric wheel 22, and the second roller brush gear 31 is meshed with the concentric wheel 22. The second roller brush gear 31 is used to drive the second roller brush to rotate, so that the driven wheel 21 drives the concentric wheel 22 to rotate synchronously, and then the concentric wheel 22 drives the second roller brush gear 31 to rotate, and the second roller brush gear 31 drives the second roller brush to rotate, so as to stir up the garbage on the bottom and wall of the swimming pool, thereby further improving the cleaning ability and cleaning efficiency of the swimming pool cleaning device. The driven wheel 21 and the walking wheel 20 jointly drive the swimming pool cleaning device to move, and at the same time, the first roller and the second roller jointly clean the dirt on the bottom and wall of the swimming pool. The movement of the four components is synchronously driven by a driving source, which further saves energy consumption, ensures the endurance of the swimming pool cleaning device, and improves the user experience.

[0043] In one embodiment, the second transition gear 12 is further included, and the concentric wheel 22, the second transition gear 12 and the second roller brush gear 31 are meshed in sequence. The second transition gear 12 can also change the rotation direction of the second roller brush gear 31, so that the rotation direction of the second roller brush is the same as the forward direction of the driven wheel 21, so that the second roller brush can push away the garbage on the bottom and wall of the pool after stirring it down, reducing the obstruction to the movement of the swimming pool cleaning device. In addition, the second transition gear 12 can also change the transmission ratio between the concentric wheel 22 and the second roller brush gear 31, thereby changing the rotation speed of the second roller brush to adapt to different dirt in the swimming pool and improve its cleaning effect.

[0044] In other embodiments, multiple second transition gears 12 may be provided, and the multiple second transition gears 12 are adjacent to each other, and the two adjacent second transition gears 12 are meshed with each other, and the first and last second transition gears 12 are respectively meshed with the concentric wheel 22 and the second roller brush gear 31. The multiple second transition gears 12 can more flexibly change the transmission ratio between the second driven gear and the second roller brush gear 31 to meet more different cleaning requirements. When the number of the second transition gears 12 is an odd number, the rotation direction of the second roller brush is the same as the forward direction of the driven wheel 21, and the second roller brush can push away the garbage on the bottom and wall of the pool after stirring it down. When the number of the second transition gears 12 is an even number, the rotation direction of the second roller brush is opposite to the jacking direction of the driven wheel 21, so that the garbage stirred down by the second roller brush can be pushed to the water inlet at the middle of the lower part of the swimming pool cleaning device by the second roller brush, so that the water inlet can suck the dirt, and collect the dirt through the garbage filter box connected to the water inlet, thereby improving the cleaning efficiency of the swimming pool cleaning device.

[0045] In one embodiment, the driving mechanism of the swimming pool cleaning device further includes a driven wheel, a second roller brush gear and a track, and the track is tensioned on the running wheel and the driven wheel, so that the driven wheel can rotate synchronously under the drive of the running wheel, and synchronously drive the swimming pool cleaning device to move with the running wheel. A second inner gear ring is provided on the inner side of the driven wheel, and the second roller brush gear is meshed with the second inner gear ring. The second roller brush gear is used to drive the second roller brush to rotate. The concentric wheel can drive the second roller brush gear to rotate synchronously through its second inner gear ring, and then the second roller brush gear drives the second roller brush to rotate, stirring up the garbage on the bottom and wall of the swimming pool, further improving the cleaning ability and cleaning efficiency of the swimming pool cleaning device. In this embodiment, there is no need for a concentric wheel, and the overall structure is simpler, the cost is lower, the structure is more compact, and the space occupancy is smaller. In other embodiments, the second roller brush gear and the second inner gear ring can also be meshed and driven by a third transition gear, and the number of the third transition gears can be an odd number or an even number.

[0046] In one embodiment, outer ring gears are provided on the peripheries of the traveling wheel 20 and the driven wheel 21, and a plurality of first belt teeth matching the outer ring gears are provided on the inner surface of the track 23. When the track 23 is tensioned on the traveling wheel 20 and the driven wheel 21, the first belt teeth are respectively meshed with the outer ring gears on the peripheries of the traveling wheel 20 and the driven wheel 21, so that the belt can be firmly tensioned on the traveling wheel 20 and the driven wheel 21, and the traveling wheel 20 can more reliably drive the driven wheel 21 to rotate synchronously, thereby ensuring that the swimming pool cleaning machine device can move stably.

[0047] In one embodiment, the outer surface of the track 23 is further provided with a plurality of second belt teeth 24, which enable the track 23 to more securely grip the bottom and walls of the swimming pool, thereby improving the grip and wall climbing ability of the swimming pool cleaning device, and further ensuring that the swimming pool cleaning machine device can move stably.

[0048] In one embodiment, the swimming pool cleaning device includes a pair of driving mechanisms for the swimming pool cleaning device, and the pair of driving mechanisms for the swimming pool cleaning device are respectively arranged on both sides of the main body. The pair of driving sources respectively drive the pair of output gears 10 and the pair of driven wheels 21 to rotate. When the pair of output gears 10 move at the same speed and in the same direction, the swimming pool cleaning device can move forward or backward. When the pair of output gears 10 move at different speeds or in opposite directions, the swimming pool cleaning device can turn.

[0049] In one embodiment, the swimming pool cleaning device further includes two roller brushes, namely a first roller brush and a second roller brush. The output gear 10 drives the first roller brush gear 30 to rotate, and the first roller brush gear 30 drives the first roller brush to rotate; the output gear 10 drives the second roller brush gear 31 to rotate through the distance between the running wheel 20 and the driven wheel 21, and the second roller brush gear 31 drives the second roller brush to rotate, that is, the driving force of the first roller brush does not pass through the running wheel, and the driving force transmission of the first roller brush is more direct and simple, reducing the power conversion between multiple machines, and the transmission efficiency is higher.
