It will be apparent, however, to those skilled in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0045] It should be noted that the terms used herein are only used to describe specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0046] Exemplary embodiments according to the present application will now be described in detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to the embodiments set forth herein. It should be understood that the embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0047] As shown in FIGS. 1-12, embodiments of the first aspect of the present application provide a transmission device 100, embodiments of the second aspect of the present application provide a cleaning module 200, and embodiments of the third aspect of the present application provide a cleaning device, wherein the transmission device 100 is applied to the cleaning module 200, the cleaning module 200 is applied to the cleaning device, and the cleaning device can be a robot vacuum cleaner, a sweeping and mopping integrated machine, or other cleaning robot that meets the requirements.

[0048] Specifically, the cleaning device includes but is not limited to a machine body, a cleaning system, a driving system, etc. The above-mentioned systems cooperate with each other to enable the cleaning device to move autonomously to achieve cleaning functions. The functional elements that constitute the above-mentioned systems in the cleaning device are integrally arranged in the machine body. It can be understood that the cleaning device can be a self-moving cleaning device, wherein the self-moving cleaning device is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation.

[0049] The machine body includes a front portion and a rear portion, and has an approximately circular shape or other shapes, including but not limited to an approximately D-shaped with a front and a rear circle, and a rectangular or square shape with a front and a rear.

[0050] The cleaning system includes a dry cleaning system, i.e., the cleaning device can be a robot vacuum cleaner, or the cleaning system includes a wet cleaning system and a dry cleaning system, i.e., the cleaning device can be a sweeping and mopping integrated machine.

[0051] The dry cleaning system can include a rolling brush, a dust box, and a dust suction fan. The rolling brush with a certain interference with the ground sweeps the garbage on the ground and brings it to the front of the dust suction port between the rolling brush and the dust box, and then the garbage is sucked into the dust box by the suction gas generated by the dust suction fan.

[0052] Further, the cleaning device provided by the embodiments of the present application, the cleaning system can further include a side brush assembly 210, the side brush assembly 210 is rotatably connected with the machine body, and is used to move the debris and other sundries outside the rolling brush area to the rolling brush area of the cleaning system.

[0053] At present, the transmission device of the side brush assembly in the related art is simple in design and single in function, and can only drive the side brush assembly to rotate for cleaning, so that the position of the side brush assembly is relatively fixed, resulting in a small cleaning range. For example, the current side brush assembly is located below the machine body, and most of the side brush assemblies are located inside the machine body in the horizontal direction, and only a small part of the side brush assemblies are located outside the machine body in the horizontal direction, such as only part of the bristles of the side brush assembly is located outside the machine body in the horizontal direction. Due to the limitation of the machine body, the current cleaning device cannot clean the surface to be cleaned in the corner, which affects the cleaning effect.

[0054] Therefore, as shown in FIG. 1, FIG. 2 and FIG. 3, the embodiment of the first aspect of the present application provides a transmission device 100 applied to a cleaning device, the cleaning device comprising a machine body and a brush assembly 210, the transmission device 100 comprising: a rotating body 120, a swing arm 130 and an elastic member 140, the rotating body 120 being arranged to rotate relative to the machine body, the elastic member 140 connecting the rotating body 120 and the swing arm 130, and the elastic member 140 being configured to keep the rotating body 120 and the swing arm 130 in a relatively static position, the brush assembly 210 being arranged on the swing arm 130, wherein the rotating body 120 rotates to drive the brush assembly 210 to switch between a first operating position and a second operating position through the swing arm 130.

[0055] The transmission device 100 provided by the embodiment can make the rotating body 120 rotate relative to the machine body according to the cleaning range requirement of the cleaning device, drive the brush assembly 210 to switch between the first operating position and the second operating position through the swing arm 130, move the brush assembly 210 to the operating position meeting the corresponding cleaning range requirement, meet the requirement of different cleaning ranges, expand the cleaning range of the brush assembly 210, and be beneficial to improving the cleaning effect and improving the cleaning experience of the user.

[0056] In the above embodiment, it should be noted that the elastic member 140 connecting the rotating body 120 and the swing arm 130 can be that the elastic member 140 is directly connected with the rotating body 120 or the swing arm 130, or the elastic member 140 is indirectly connected with the rotating body 120 or the swing arm 130 through other components. Since the elastic member 140 connects the rotating body 120 and the swing arm 130, when the brush assembly 210 collides with an obstacle and is subjected to a force, the elastic member 140 can play a good buffering effect, reduce the influence of the obstacle on the brush assembly 210, the swing arm 130 and the rotating body 120, and be beneficial to improving the reliability of the brush assembly 210 and the transmission device 100.

[0057] The elastic member 140 is configured to keep the rotating body 120 and the swing arm 130 in a relatively static position. The rotating body 120 and the swing arm 130 can be kept relatively static under the action of the elastic member 140, or the rotating body 120 and the swing arm 130 can be kept relatively static under the cooperation of the elastic member 140 and other structures. The rotating body 120 and the swing arm 130 being kept relatively static means that the rotating body 120 and the swing arm 130 can move as a whole. Therefore, when the rotating body 120 is driven to rotate relative to the machine body, the swing arm 130 can rotate synchronously with the rotating body 120, and then drive the side brush assembly 210 arranged on the swing arm 130 to rotate, so as to switch the side brush assembly 210 between the first operating position and the second operating position, so as to meet the needs of different cleaning ranges and expand the cleaning range of the side brush assembly 210. This kind of transmission arrangement is simple in structure and convenient in transmission, and the elastic member 140 is low in cost and small in size, which can meet the design requirements of low cost and compact structure of the transmission device 100.

[0058] The side brush assembly 210 in the first operating position and the second operating position is located at different positions of the machine body in the horizontal direction, that is, the orthographic projection of the side brush assembly 210 in the first operating position and the second operating position on the horizontal plane is located at different positions of the orthographic projection area of the machine body on the horizontal plane. Specifically, at least part of the side brush assembly 210 in the first operating position is located inside the machine body in the horizontal direction, at least part of the side brush assembly 210 in the second operating position is located outside the machine body in the horizontal direction, and the area of the side brush assembly 210 in the second operating position outside the machine body in the horizontal direction is greater than the area of the side brush assembly 210 in the first operating position outside the machine body in the horizontal direction.

[0059] That is, the edge brush assembly 210 in the first operating position can have a horizontal plane projection that is entirely within the horizontal plane projection area of the machine body, or the edge brush assembly 210 in the first operating position can have a horizontal plane projection that is partially within the horizontal plane projection area of the machine body and partially outside the horizontal plane projection area of the machine body. The edge brush assembly 210 in the second operating position can have a horizontal plane projection that is entirely outside the horizontal plane projection area of the machine body, or the edge brush assembly 210 in the second operating position can have a horizontal plane projection that is partially within the horizontal plane projection area of the machine body and partially outside the horizontal plane projection area of the machine body. Moreover, the area of the horizontal plane projection of the edge brush assembly 210 in the second operating position that is outside the horizontal plane projection area of the machine body is greater than the area of the horizontal plane projection of the edge brush assembly 210 in the first operating position that is outside the horizontal plane projection area of the machine body, that is, the area of the edge brush assembly 210 in the second operating position that is outside the machine body is greater than the area of the edge brush assembly 210 in the first operating position that is outside the machine body, so that the edge brush assembly 210 in the second operating position can be in contact with more surfaces to be cleaned outside the machine body, thereby increasing the cleaning range of the edge brush assembly 210 and enabling auxiliary cleaning operation in the corner area. Thus, the edge brush assembly 210 can be driven to switch between the first operating position and the second operating position according to the cleaning range requirement of the cleaning device, specifically according to the cleaning range requirement of the edge brush assembly 210, so as to move the edge brush assembly 210 to an operating position that meets the corresponding cleaning range requirement, that is, the edge brush assembly 210 can perform auxiliary cleaning operation in the first operating position, and the edge brush assembly 210 can also perform auxiliary cleaning operation in the second operating position to meet the requirement of different cleaning ranges, thereby expanding the auxiliary cleaning range, i.e., expanding the cleaning range of the cleaning device, improving the cleaning effect, and improving the user's cleaning experience.

[0060] It should be noted that when the edge brush assembly 210 in the first operating position is entirely within the machine body in the horizontal direction, the area of the edge brush assembly 210 in the first operating position that is outside the machine body in the horizontal direction is zero, and at this time, the area of the edge brush assembly 210 in the second operating position that is outside the machine body in the horizontal direction is still greater than the area of the edge brush assembly 210 in the first operating position that is outside the machine body in the horizontal direction.

[0061] At least part of the side brush assembly 210 in the second operating position is located outside the machine body in the horizontal direction, and the area of the side brush assembly 210 in the second operating position outside the machine body is larger than the area of the side brush assembly 210 in the first operating position outside the machine body in the horizontal direction, so that the cleaning range of the side brush assembly 210 in the second operating position can exceed the edge of the machine body walking range, and the area exposed outside the machine body is larger compared with the side brush assembly 210 in the first operating position, so that comprehensive cleaning of the corner position that cannot be attached to the machine body can be realized, thereby improving the cleaning range of the side brush assembly 210 and improving the cleaning effect of the cleaning equipment.

[0062] Specifically, when the side brush assembly 210 is in the first operating position, in the horizontal direction, the side brush assembly 210 can be located entirely inside the machine body, or most of the side brush assembly 210 is located inside the machine body and a small part of the side brush assembly 210 is located outside the machine body. At this time, the side brush assembly 210 can be understood as being retracted into the machine body, and the side brush assembly 210 can be used for regular cleaning operation. When the side brush assembly 210 is in the second operating position, in the horizontal direction, the side brush assembly 210 can be located entirely outside the machine body, or most of the side brush assembly 210 is located outside the machine body and a small part of the side brush assembly 210 is located inside the machine body. At this time, the side brush assembly 210 can be understood as being extended outside the machine body, and the side brush assembly 210 can be used for corner cleaning operation.

[0063] Further, the side brush assembly 210 can be selectively driven to switch between the first operating position and the second operating position according to the need of the cleaning equipment to perform corner cleaning, such as moving the side brush assembly 210 to the first operating position for regular cleaning operation and moving the side brush assembly 210 to the second operating position for corner cleaning operation, thereby meeting different functional requirements of the cleaning equipment and improving the intelligence of the automatic cleaning equipment.

[0064] In some possible implementation embodiments provided in the present application, the rotating direction of the swing arm 130 during switching of the side brush assembly 210 from the first operating position to the second operating position is the first direction, and the swing arm 130 is configured to rotate relative to the rotating body 120 in the first direction from the relatively static position under the action of an external force, so that the elastic member 140 is deformed to accumulate elastic potential energy.

[0065] The rotating direction of the swing arm 130 during switching of the side brush assembly 210 from the first operating position to the second operating position can be as shown by the arrow X in FIG. 4, that is, the first direction can be as shown by the arrow X. The rotating direction of the swing arm 130 during switching of the side brush assembly 210 from the second operating position to the first operating position can be as shown by the arrow Y in FIG. 4, that is, the second direction can be as shown by the arrow X.

[0066] Since the brush assembly 210 is located outside the machine body in the horizontal direction during the operation of the cleaning device, the brush assembly 210 can collide with an obstacle during the operation of the cleaning device, in particular, the brush assembly 210 can collide with an obstacle located in front of the machine body during the operation of the cleaning device. In the embodiment, the swing arm 130 is configured to rotate relative to the rotating body 120 in the first direction from the relatively static position under the action of an external force, that is, when the brush assembly 210 collides with an obstacle located in front of the machine body during the operation of the cleaning device, the swing arm 130 can be driven to continue to rotate relative to the rotating body 120 in the first direction from the relatively static position, and the process can make the elastic member 140 deform to accumulate elastic potential energy. Thus, the elastic member 140 can play a good buffering role on the brush assembly 210 that encounters an obstacle, reduce the damage of the obstacle to the brush assembly 210, and be beneficial to improving the reliability of the brush assembly 210 and prolonging the service life of the cleaning device.

[0067] In some possible implementation embodiments provided in the present application, a limiting portion is arranged on the rotating body 120 and / or the swing arm 130, and the elastic member 140 cooperates with the limiting portion to keep the rotating body 120 and the swing arm 130 in the relatively static position.

[0068] That is, in the embodiment, the limiting portion arranged on the rotating body 120 and / or the swing arm 130 cooperates with the elastic member 140 to stably keep the rotating body 120 and the swing arm 130 in the relatively static position, so that the rotating body 120 and the swing arm 130 can move as a whole to rotate the rotating body 120, and the swing arm 130 synchronously drives the brush assembly 210 arranged on the swing arm 130 to rotate, so as to switch the brush assembly 210 between the first operating position and the second operating position.

[0069] The limiting portion can be arranged on the rotating body 120, or the limiting portion can be arranged on the swing arm 130, or the limiting portion can be arranged on both the rotating body 120 and the swing arm 130. It can be understood that the relatively static position of the rotating body 120 and the swing arm 130 can be destroyed under the action of an external force on the brush assembly 210, and at this time, the buffering effect of the elastic member 140 can play a good protection role on the rotating body 120, the swing arm 130 and the brush assembly 210.

[0070] In some possible implementation embodiments provided in the present application, the elastic member 140 releases elastic potential energy to drive the swing arm 130 to rotate in the second direction opposite to the first direction, so that the swing arm 130 is capable of returning to the relatively static position under the action of the elastic member 140. In the process of releasing the elastic potential energy, the elastic member 140 is capable of pushing or bouncing away the obstacle near the front of the brush assembly 210 in the second direction, so as to realize the cleaning operation on the obstacle, thereby improving the cleaning effect of the brush assembly 210 and the cleaning effect of the cleaning device.

[0071] Specifically, when the swing arm 130 does not encounter the obstacle, the swing arm 130 and the rotating body 120 are kept in the relatively static position under the action of the elastic member 140 and the limiting portion, and the rotating torque of the rotating body 120 acting on the swing arm 130 is constant. When the brush assembly 210 in the second operating position encounters the obstacle, specifically, the brush assembly 210 collides with the obstacle in front of the cleaning device in the advancing direction, so that the swing arm 130 is forced to continue to rotate relative to the rotating body 120 in the first direction from the relatively static position, which deforms the elastic member 140 to accumulate elastic potential energy, so that the rotating torque of the rotating body 120 acting on the swing arm 130 increases, that is, the rotating torque of the rotating body 120 acting on the swing arm 130 changes from weak to strong, so that the brush assembly 210 is capable of passing over the obstacle or bouncing the obstacle away, thereby improving the cleaning effect of the brush assembly 210.

[0072] It can be understood that, due to different forces of the obstacle acting on the brush assembly 210, the elastic member 140 accumulates different forces, and thus the rotating torque of the rotating body 120 acting on the swing arm 130 is different, so that the rotating torque of the rotating body 120 acting on the swing arm 130 changes according to the gravity of the obstacle. Meanwhile, when the cleaning device continues to advance, the force of the same obstacle acting on the brush assembly 210 changes, and under the action of the elastic member 140, the rotating torque of the rotating body 120 acting on the swing arm 130 also changes, so that the swing arm 130 is capable of rotating with variable torque to pass over the obstacle or bounce the obstacle away.

[0073] It can be understood that, for the obstacle such as clothes or books, the force acting on the brush assembly 210 is small, and the angle of the brush assembly 210 continuing to rotate relative to the rotating body 120 in the first direction from the relatively static position is small. In the process of the elastic member 140 releasing the elastic potential energy, the brush assembly 210 is capable of pushing or bouncing away the obstacle with small gravity, so as to realize the cleaning on the obstacle and improve the cleaning effect. For the obstacle such as tables and chairs, when the brush assembly 210 encounters the obstacle, the angle of the swing arm 130 continuing to rotate relative to the rotating body 120 in the first direction from the relatively static position is large. In this process, the brush assembly 210 is capable of passing over or avoiding the obstacle with large gravity, so as to realize the obstacle avoidance operation.

[0074] In some possible implementation examples provided by the present application, the rotation direction of the swing arm 130 during switching of the side brush assembly 210 from the second operating position to the first operating position is the second direction, and the elastic member 140 and the limiting portion are further used to hinder the swing arm 130 from rotating relative to the rotating body 120 along the second direction from the relative static position.

[0075] That is, under the action of the elastic member 140 and the limiting portion, for the swing arm 130 and the rotating body 120 in the relative static position, the swing arm 130 can rotate relative to the rotating body 120 along the first direction under the action of an external force, and the swing arm 130 cannot rotate relative to the rotating body 120 along the second direction under the action of an external force, thereby limiting the rotation range of the swing arm 130 relative to the rotating body 120, avoiding the possibility that the swing arm 130 rotates relative to the rotating body 120 along the second direction under the action of an external force and collides with other structures of the transmission device 100 or other structures of the cleaning equipment to be damaged, and further playing a good protection role on the swing arm 130, other structures of the transmission device 100, and other structures of the cleaning equipment, which is beneficial to prolong the service life of the swing arm 130, improve the reliability of the transmission device 100, and improve the reliability of the cleaning equipment.

[0076] As shown in FIGS. 1, 2, 9 and 10, in some possible implementation examples provided by the present application, the elastic member 140 is a torsion spring, the torsion spring is sleeved on the rotating shaft of the swing arm 130 or the rotating shaft of the rotating body 120, the first torsion arm 141 of the torsion spring is connected with the swing arm 130, and the second torsion arm 142 of the torsion spring is connected with the rotating body 120, so that the swing arm 130 and the rotating body 120 can be reliably and stably kept in the relative static position through the torsion spring and the limiting portion arranged on the swing arm 130 and / or the rotating body 120, so that the first driving assembly 110 can smoothly and accurately make the side brush assembly 210 switch before the first operating position and the second operating position, to ensure the effectiveness and accuracy of transmission. At the same time, after the side brush assembly 210 collides with an obstacle, the torsion spring has a good buffering effect, so as to prolong the service life of the side brush assembly 210 and can bounce or avoid the obstacle.

[0077] The torsion spring has the advantages of high torsional stiffness and good torsional stability, so that the transmission accuracy and stability can be ensured, and the torsion spring has the advantages of small size and light weight, which can meet the design requirements of compact structure, small size and light weight of the transmission device 100, and is suitable for popularization and application.

[0078] As shown in FIG. 4, FIG. 5, FIG. 6 and FIG. 9, in some possible implementation embodiments provided by the present application, the transmission device 100 further comprises a connecting shaft 150, the connecting shaft 150 is fixedly arranged relative to the machine body, the swing arm 130 and the rotating body 120 are coaxially arranged with the connecting shaft 150 as the rotation axis, and the torsional spring is sleeved on the connecting shaft 150.

[0079] Therefore, the coaxial arrangement of the swing arm 130 and the rotating body 120 is realized through the connecting shaft 150, and the mounting position of the torsional spring is provided, and the layout of the swing arm 130, the rotating body 120 and the elastic member 140 is compact, which can meet the design requirements of compact structure and small volume of the transmission device 100, reduce the space occupied by the transmission device 100, and meet the design requirements of compact structure and small volume of the cleaning equipment.

[0080] It should be noted that the connecting shaft 150 is fixedly arranged relative to the machine body, which can be that the connecting shaft 150 is directly fixed on the machine body, or other components are fixedly connected with the machine body, and the connecting shaft 150 is fixed on the other components to indirectly fix the connecting shaft 150 on the machine body.

[0081] Among them, the swing arm 130 and the rotating body 120 are coaxially arranged with the connecting shaft 150 as the rotation center, which can be that one end of the swing arm 130 is sleeved on the outside of the connecting shaft 150, the other end of the swing arm 130 is distributed on part of the circumference of the connecting shaft 150; one end of the rotating body 120 is sleeved on the outside of the connecting shaft 150, and the other end of the rotating body 120 is distributed on another part of the circumference of the connecting shaft 150, that is, the other end of the swing arm 130 and the other end of the rotating body 120 are distributed at different positions along the circumference of the connecting shaft 150.

[0082] As shown in FIG. 1, FIG. 7 and FIG. 8, in some possible implementation embodiments provided by the present application, the rotating body 120 is arranged in a fan-shaped structure, thereby providing arrangement space for the swing arm 130 arranged on the circumference of the connecting shaft 150, so that the rotating body 120 and the swing arm 130 can be coaxially arranged with the connecting shaft 150 as the rotation center.

[0083] In the above embodiment, the number of torsional springs is at least one, that is, the number of torsional springs can be one, two, three, four or more. It can be understood that the number of torsional springs can be reasonably set according to the stability of synchronous motion of the swing arm 130 and the rotating body 120 and cost requirements. Among them, the more the number of torsional springs, the higher the cost, and the higher the stability of synchronous motion of the swing arm 130 and the rotating body 120.

[0084] As shown in FIG. 9 and FIG. 10, in some possible implementation embodiments provided by the present application, the limiting part includes a first slot arranged on the swing arm 130, and the first torsion arm 141 is inserted into the first slot. Thus, the movement range of the first torsion arm 141 is limited by the first slot, and the torsion of the torsion spring is limited.

[0085] As shown in FIG. 8 and FIG. 9, in some possible implementation embodiments provided by the present application, the limiting part includes a second slot 121 arranged on the rotating body 120, and the second torsion arm 142 is inserted into the second slot 121. Thus, the movement range of the second torsion arm 142 is limited by the second slot 121, and the torsion of the torsion spring is limited.

[0086] Thus, as shown in FIG. 4, FIG. 5 and FIG. 6, the rotating body 120 and the swing arm 130 are kept in the relatively static position by the cooperation of the first slot and the first torsion arm 141 and the cooperation of the second slot 121 and the second torsion arm 142, and the swing arm 130 can be prevented from rotating relative to the rotating body 120 along the second direction from the relatively static position. Under the action of an external force, the swing arm 130 can rotate relative to the rotating body 120 along the first direction from the relatively static position.

[0087] As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 5, FIG. 6, FIG. 11 and FIG. 12, in some possible implementation embodiments provided by the present application, the transmission device 100 further includes a first driving assembly 110, the first driving assembly 110 being configured to drive the rotating body 120 to rotate; a housing 160, the housing 160 being connected with a machine body, one side of the housing 160 being provided with an opening 161, the first driving assembly 110, the rotating body 120 and the elastic member 140 being installed inside the housing 160, the rotating body 120 being rotationally arranged relative to the housing 160, the swing arm 130 being arranged through the opening 161 and rotationally arranged relative to the housing 160, and the shape of the opening 161 being matched with the movement space of the swing arm 130.

[0088] In the embodiment, the first driving assembly 110 provides power for the rotation of the rotating body 120, the shell 160 provides a mounting space for the first driving assembly 110, the rotating body 120, the elastic member 140 and the partial swing arm 130, and the arrangement of the shell 160 plays a good protection role for the first driving assembly 110, the rotating body 120, the elastic member 140 and the partial swing arm 130 mounted in the shell 160, which is conducive to prolonging the service life of the first driving assembly 110, the rotating body 120, the elastic member 140 and the swing arm 130. The shell 160 is connected with the machine body, the entire transmission device 100 can be fixed on the machine body, and the operation is simple and convenient to disassemble and assemble. Since the shell 160 is connected with the machine body, the rotating body 120 and the swing arm 130 are arranged to rotate relative to the shell 160, so that the rotating body 120 and the swing arm 130 are arranged to rotate relative to the machine body. The swing arm 130 is arranged in the opening 161, so that a part of the swing arm 130 can be connected with the elastic member 140 located in the shell 160, and another part of the swing arm 130 is located outside the shell 160 to connect the edge brush assembly 210. The shape of the opening 161 matches the movement space of the swing arm 130, so that the opening 161 of the shell 160 does not hinder or interfere with the movement of the swing arm 130, so that the swing arm 130 can smoothly move between the openings 161 to ensure that the edge brush assembly 210 can be smoothly switched between the first operating position and the second operating position, and after the edge brush assembly 210 collides with the obstacle, the swing arm 130 can be smoothly rotated without interfering with the shell 160.

[0089] Specifically, the shell 160 can be detachably connected with the machine body by at least one of a bolt structure, a clamping structure, a mortise and tenon structure, a plug-in structure and a magnetic attraction structure, so as to facilitate disassembly and assembly of the entire transmission device 100 and the machine body, and facilitate maintenance and maintenance.

[0090] Further, as shown in FIGS. 5 and 6, the connecting shaft 150 can be mounted on the shell 160, and since the shell 160 is fixedly connected with the machine body, the relative fixed arrangement of the connecting shaft 150 and the machine body is realized.

[0091] As shown in FIGS. 4 and 5, in some possible implemented embodiments provided in the application, the first driving assembly 110 includes a first driving part 111 and a first transmission part 112, and the first transmission part 112 is in transmission connection with the first driving part 111 and the rotating body 120. Thus, the first driving part 111 works, and the rotating body 120 can be driven to rotate through the first transmission part 112.

[0092] Specifically, the first driving part 111 can be an electric motor, and the first transmission part 112 can be at least one of a gear transmission, a chain transmission, and a belt transmission. As shown in FIG. 5, the first transmission part 112 is a gear, and the rotating body 120 is provided with a tooth portion 122 engaged with the gear to realize power transmission. It can be understood that the first driving part 111 can realize rotation in two directions, such as an electric motor that can realize forward rotation and reverse rotation, so that the rotating body 120 can rotate in different directions to realize switching of the side brush assembly 210 between the first operating position and the second operating position through the swing arm 130.

[0093] As shown in FIGS. 4, 5, 6, 11, and 12, in some possible implemented embodiments provided in the present application, the housing 160 of the transmission device 100 is provided with a first installation space 163 and a second installation space 164 connected through an avoiding opening 162, the first driving part 111 is located in the first installation space 163, the rotating body 120 and the elastic member 140 are located in the second installation space 164, the first transmission part 112 connects the first driving part 111 and the rotating body 120 through the avoiding opening 162, and the opening 161 of the housing 160 is connected with the second installation space 164.

[0094] In the embodiment, the first driving part 111 is arranged in the first installation space 163 alone, and the rotating body 120, the elastic member 140, and part of the rotating body 120 are arranged in the second installation space 164. Since the opening 161 of the housing 160 is connected with the second installation space 164, the swing arm 130 can move in the second installation space 164, thereby avoiding the arrangement of the first driving part 111 and the swing arm 130 in the same installation space, so that the swing arm 130 will not directly hit the first driving part 111 in the process of rotation to damage the first driving part 111 and / or the swing arm 130, thereby greatly improving the reliability of the first driving part 111, prolonging the service life of the first driving part, and improving the reliability of the transmission device 100.

[0095] As shown in FIG. 5, the first installation space 163 can pass through the top and bottom of the housing 160, that is, the first installation space 163 can be understood as an installation channel passing through the housing 160 in the direction from the top to the bottom of the housing 160. This arrangement is conducive to disassembly and assembly of the first driving part 111, thereby facilitating maintenance and replacement of the first driving part 111, and at the same time, is conducive to ventilation and heat dissipation of the first driving part 111, further improving the service life of the first driving part 111.

[0096] As shown in FIG. 1, FIG. 2 and FIG. 6, in some possible implementation embodiments provided by the present application, the transmission device 100 further comprises a second driving assembly 170, the second driving assembly 170 is installed on the swing arm 130, and the second driving assembly 170 is used to be connected with the brush assembly 210 to drive the brush assembly 210 to rotate relative to the swing arm 130, so that the brush assembly 210 interferes with the surface to be cleaned to realize the auxiliary cleaning function.

[0097] As shown in FIG. 1, FIG. 2 and FIG. 6, in some possible implementation embodiments provided by the present application, the second driving assembly 170 and the brush assembly 210 are located on the swing arm 130 outside the housing 160 of the transmission device 100. In this way, the disassembly and assembly of the second driving assembly 170 and the swing arm 130, and the disassembly and assembly of the brush assembly 210 and the swing arm 130 are facilitated, and the installation efficiency and the maintenance efficiency of the second driving assembly 170 and the brush assembly 210 are improved. At the same time, the brush assembly 210 is arranged outside the housing 160 to facilitate the interference between the brush assembly 210 and the surface to be cleaned to realize the cleaning operation.

[0098] Specifically, the shell of the second driving assembly 170 can be detachably connected with the swing arm 130 through at least one of a bolt structure, a clamping structure, a plug-in structure, a mortise and tenon structure, and a magnetic attraction structure.

[0099] It can be understood that the brush assembly 210 as a whole can be movably arranged on the swing arm 130, for example, the brush assembly 210 can be directly power-connected with the second driving assembly 170, so that the second driving assembly 170 drives the brush assembly 210 to rotate relative to the swing arm 130 to realize the cleaning operation. In this example, the brush assembly 210 and the second driving assembly 170 can be detachably connected through at least one of a bolt structure, a clamping structure, a plug-in structure, a mortise and tenon structure, and a magnetic attraction structure.

[0100] Alternatively, the brush assembly 210 comprises a mounting seat fixedly connected with the swing arm 130, and a brush disc movably arranged relative to the mounting seat, the brush disc is connected with the second driving assembly 170, so that the second driving assembly 170 drives the brush disc to rotate relative to the swing arm 130 to realize the cleaning operation. In this example, the brush disc of the brush assembly 210 can be detachably connected with the swing arm 130 through at least one of a bolt structure, a clamping structure, a plug-in structure, a mortise and tenon structure, and a magnetic attraction structure.

[0101] As shown in FIG. 6, in some possible implementation embodiments provided by the present application, the second driving assembly 170 comprises a second driving part 171 and a second transmission part 172, the second driving part 171 and the brush assembly 210 are located on both sides of the swing arm 130, and the second transmission part 172 is located in the swing arm 130.

[0102] In this embodiment, since the side brush assembly 210 needs to interfere with the surface to be cleaned to realize the cleaning operation, the side brush assembly 210 is usually arranged at the bottom of the swing arm 130. By arranging the second driving part 171 and the side brush assembly 210 on both sides of the swing arm 130 and arranging the second driving part 171 at the top of the swing arm 130, the problem that the second driving part 171 arranged at the bottom of the swing arm 130 interferes with the surface to be cleaned and affects the interference of the side brush assembly 210 with the surface to be cleaned can be avoided, and at the same time, the swing arm 130 can provide good and stable support for the second driving part 171, so as to improve the reliability and stability of the connection between the second driving part 171 and the swing arm 130. By arranging the second transmission part 172 inside the swing arm 130, the swing arm 130 can provide good protection for the second transmission part 172, which is conducive to prolonging the service life of the second transmission part 172 and improving the overall reliability of the transmission device 100.

[0103] Specifically, the second driving part 171 can be a motor, and the second transmission part 172 can be at least one of a gear transmission, a chain transmission, and a belt transmission. As shown in FIG. 6, the second transmission part 172 is a gear mechanism, and the output shaft of the gear mechanism is connected with the side brush assembly 210.

[0104] As shown in FIG. 3, in some possible implemented embodiments provided in the present application, the transmission device 100 further comprises a position detection device 180, which is configured to detect the rotation position of the rotating body 120, and the first driving assembly 110 stops rotating or rotates according to the detection result of the position detection device 180.

[0105] The position detection device 180 can detect the rotation position of the rotating body 120, and thus the rotation position of the swing arm 130 can be known. Therefore, when the swing arm 130 rotates to a suitable position, such as when the swing arm 130 drives the side brush assembly 210 to move to the first operation position or the second operation position, the first driving assembly 110 can stop rotating according to the detection result of the position detection device 180 at this time, so that the side brush assembly 210 can be kept in the first operation position or the second operation position, thereby realizing accurate switching of the first operation position or the second operation position. It can be understood that when the rotating body 120 rotates and the swing arm 130 drives the side brush assembly 210 to move to the first operation position or the second operation position, the first driving assembly 110 can continue to rotate according to the detection result of the position detection device 180 at this time, so as to drive the side brush assembly 210 to continue to move towards the target operation position, such as the first operation position or the second operation position.

[0106] The position detection device 180 can include a photoelectric switch, a mechanical switch, or other detection mechanisms that meet the requirements.

[0107] As shown in FIG. 3, FIG. 6, FIG. 7 and FIG. 8, in some possible implementation embodiments provided by the present application, the position detection device 180 comprises a first position switch 181 and a second position switch 182 distributed around the rotating body 120, and the rotating body 120 is provided with a first acting part 183 and a second acting part 184, the first acting part 183 is adapted to trigger the first position switch 181 to change the detection signal, and the second acting part 184 is adapted to trigger the second position switch 182 to change the detection signal.

[0108] In this embodiment, the first position switch 181 and the second position switch 182 are arranged at intervals around the rotating body 120, so as to respectively detect the position of the brush assembly 210 reaching the first operating position and the second operating position by using the two position switches, thereby improving the accuracy of detecting whether the brush assembly 210 reaches the target operating position.

[0109] In this embodiment, the first acting part 183 and the second acting part 184 are arranged on the rotating body 120, so that the rotation of the rotating body 120 can drive the first acting part 183 and the second acting part 184 to rotate synchronously, and since the first acting part 183 and the second acting part 184 are arranged at intervals along the rotation direction of the rotating body 120, when the rotating body 120 rotates to a suitable position, the first acting part 183 acts on the first position switch 181 to make the first position switch 181 change the detection signal. For example, when the first position switch 181 is a first photoelectric switch, the first acting part 183 is located between the light emitting part and the light receiving part of the first photoelectric switch to prevent the light receiving part from receiving the light signal emitted by the light emitting part, so that the first photoelectric switch changes the detection signal, indicating that the rotating body 120 rotates to the suitable position and the brush assembly 210 is located at the first operating position. At this time, the first driving part 111 of the first driving assembly 110 can stop rotating according to the detection signal of the first position switch 181, so as to maintain the brush assembly 210 at the first operating position.

[0110] When the rotating body 120 rotates to a suitable position, the second acting part 184 acts on the second position switch 182 to make the second position switch 182 change the detection signal. For example, when the second position switch 182 is a second photoelectric switch, the second acting part 184 is located between the light emitting part and the light receiving part of the second photoelectric switch to prevent the light receiving part from receiving the light signal emitted by the light emitting part, so that the second photoelectric switch changes the detection signal, indicating that the rotating body 120 rotates to the suitable position and the brush assembly 210 is located at the second operating position. At this time, the first driving part 111 of the first driving assembly 110 can stop rotating according to the detection signal of the second position switch 182, so as to maintain the brush assembly 210 at the second operating position.

[0111] Specifically, as shown in FIG. 7, the first acting part 183 and the second acting part 184 can be baffles arranged on the outer wall of the rotating body 120, and the first acting part 183 and the second acting part 184 are arranged in the rotation direction of the rotating body 120 and staggered in the axial direction of the rotating body 120.

[0112] As shown in FIGS. 11 and 12, in some possible implementation embodiments provided in the present application, the housing 160 of the transmission device 100 is provided with detection openings 165, and the first position switch 181 and the second position switch 182 are arranged outside the housing 160, and part of the first position switch 181 and part of the second position switch 182 extend into the interior of the housing 160 through the detection openings 165.

[0113] Therefore, the part of the first position switch 181 located in the housing 160 cooperates with the first acting part 183, and the part of the second position switch 182 located in the housing 160 cooperates with the second acting part 184, so that the rotation position of the rotating body 120 can be reliably detected, and the working state of the first driving part 111 of the first driving assembly 110 can be accurately adjusted, so that the brush assembly 210 can be reliably and stably switched to the first operation position and the second operation position. Meanwhile, the first position switch 181 and the second position switch 182 are arranged outside the housing 160, which facilitates the disassembly of the first position switch 181 and the second position switch 182 from the housing 160, and when the first position switch 181 and the second position switch 182 need to be repaired, the rotating body 120, the swing arm 130, etc. in the housing 160 do not need to be disassembled, and the first position switch 181 and the second position switch 182 can be disassembled and replaced outside the housing 160, which is simple to operate and greatly improves the maintenance efficiency of the first position switch 181 and the second position switch 182.

[0114] It can be understood that the number of detection openings 165 is two, and the two detection openings 165 are respectively opposite to the first position switch 181 and the second position switch 182.

[0115] As shown in FIGS. 11 and 12, in the above embodiment, the interior of the housing 160 is provided with an annular groove 166 for avoiding the first acting part 183 and the second acting part 184, the detection openings 165 are located at the groove bottom of the annular groove 166, the exterior of the housing 160 is formed with recesses 167 on both sides of the annular groove 166, and the recesses 167 are provided with connecting parts 168 connected with the first position switch 181 and the second position switch 182.

[0116] Thus, when the first position switch 181 and the second position switch 182 are fixed outside the shell 160 through the connecting portions 168 in the recesses 167, the distance between the first position switch 181 and the shell 160 and the distance between the second position switch 182 and the shell 160 can be reduced, so that part of the first position switch 181 and part of the second position switch 182 can smoothly extend to the inside of the shell 160 through the detection opening 165. Since the first acting portion 183 and the second acting portion 184 protrude from the side wall of the rotating body 120, and the annular groove 166 in the inside of the shell 160 is used to avoid the first acting portion 183 and the second acting portion 184, the distance between the side wall of the rotating body 120 and the shell 160 is small. Thus, the layout of the first position switch 181, the second position switch 182, the shell 160, and the rotating body 120 is compact, the space occupied by the transmission device 100 is reduced, the design requirements of compact structure and small volume of the transmission device 100 can be met, and the design requirements of compact structure and small volume of the cleaning equipment can be met, which is suitable for popularization and application.

[0117] Specifically, the connecting portion 168 can be a connecting column, and the first position switch 181 and the second position switch 182 can be detachably connected to the shell 160 by being connected to the connecting column through bolts. Specifically, the recess 167 is located on both sides of the annular groove 166, and the connecting portion 168 is located in the recess 167. Thus, the first position switch 181 can be fixed on the shell 160 from both sides through the connecting portion 168 in the recess 167 on both sides of the annular groove 166, and the second position switch 182 can be fixed on the shell 160 from both sides, so as to ensure the reliability and stability of the connection between the first position switch 181, the second position switch 182, and the shell 160, and improve the accuracy of the rotating position detection of the rotating body 120.

[0118] As shown in FIG. 1, FIG. 1, and FIG. 3, the embodiment of the application also provides a cleaning module 200 applied to a cleaning equipment, the cleaning module 200 comprising: a brush assembly 210, and the transmission device 100 of any one of the first aspect. Specifically, the transmission device 100 further comprises a second driving assembly 170 arranged on the swing arm 130, and the brush assembly 210 is connected to the second driving assembly 170 to drive the brush assembly 210 to rotate, so as to realize the cleaning operation on the surface to be cleaned.

[0119] In the embodiment, the transmission device 100 and the side brush assembly 210 are modularly designed by arranging the side brush assembly 210 on the swing arm 130 of the transmission device 100. Therefore, the cleaning module 200 can be selectively installed on the machine body according to the design requirements of the cleaning equipment. For example, when the design of the cleaning equipment has the requirement of increasing the cleaning range by using the side brush assembly 210 to clean the corners, the cleaning module 200 provided in the embodiment can be installed on the machine body. When the design of the cleaning equipment has the requirement of using the side brush assembly 210 to perform the conventional cleaning operation, the conventional side brush assembly 210 and the transmission device 100 can be installed on the machine body. The operation is simple, the installation is convenient, the practicability is strong, and the use range is wide.

[0120] It can be understood that the transmission device 100 and the side brush assembly 210 are modularly designed. Before the cleaning module 200 is installed on the machine body, the transmission device 100 can be debugged and detected. For example, the swing arm 130 of the transmission device 100, the switching of the operating position of the side brush assembly 210, the rotation of the side brush assembly 210, and the like are debugged and detected by using an external power supply and the control program of the cleaning equipment. If the detection is unqualified, the adjustment can be directly performed. Compared with the situation that the cleaning module 200 is installed on the machine body, the swing arm 130 is rotated, the operating position of the side brush assembly 210 is switched, the rotation of the side brush assembly 210 is debugged and detected, and the like are debugged and detected after the whole machine is debugged. If the detection is unqualified, the cleaning module 200 needs to be disassembled from the machine body.
