Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically, it is an external swing gearbox for cleaning equipment. Background Technology

[0002] The "side mop" function of cleaning equipment is a specially optimized design for "blind spots" in home cleaning scenarios. Its core value lies in solving the cleaning problems of areas such as walls and around furniture legs that are difficult to reach with traditional mopping functions. Traditional side mops are generally fixed in place on the machine body, and then a lifting function is added to achieve the cleaning effect.

[0003] Most cleaning equipment on the market today features a side mop. In this system, one motor drives the mop to rotate and lift, cleaning corner areas, while another motor drives the main drive gearbox to swing outwards relative to the cleaning equipment, covering areas beyond the main body and thus increasing the cleaning range and allowing the mop to reach hard-to-reach corners. However, this design results in a complex gear transmission assembly and a large number of motors, increasing both the production cost and the overall size and weight of the cleaning equipment.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cleaning equipment external swing gearbox that can realize side-dragging rotation, lifting, and external swinging movements while reducing the number of motors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An external gearbox for a cleaning device includes a housing, a drive component disposed outside the housing, a first gear transmission assembly disposed inside the housing and connected to the drive component, a first output gear and a second output gear meshing with the first gear transmission assembly, a second gear transmission assembly disposed between the first gear transmission assembly and the second output gear, a clutch mechanism disposed on the second gear transmission assembly, and a gear disengagement mechanism disposed on the second output gear.

[0007] As a further embodiment of this utility model, the first gear transmission assembly includes a driving gear driven by the driving member, a first double gear meshing with the driving gear, a first gear meshing with the first double gear, and a second double gear meshing with the first gear.

[0008] As a further embodiment of this utility model, the second gear transmission assembly includes a second gear meshing with the second double gear, a third double gear meshing with the second gear, and a third gear meshing with the third double gear and movably meshing with the second output gear.

[0009] As a further embodiment of this utility model, a clutch mechanism is provided between the third double gear and the third gear. The clutch mechanism includes a bracket, a rotating shaft and a first spring. The rotating shaft is rotatably mounted on the bracket, and the third gear is mounted on the rotating shaft. The first spring is sleeved on the rotating shaft between the bracket and the third gear. A stop block that cooperates with the bracket is provided on the inner wall of the housing.

[0010] As a further embodiment of this utility model, the gear disengagement mechanism includes a column that slides along an arcuate groove on the second output gear and a guide rod mounted on the column via a rod head. The guide rod is movably inserted into the gap of at least one limiting block, and a second spring is sleeved on the guide rod between the limiting block and the rod head.

[0011] As a further embodiment of this utility model, the side wall of the housing is provided with a first stop position and a second stop position that cooperate with the second output gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Due to the aforementioned structural design—that is, a drive unit is installed outside the housing and a first gear transmission assembly, a first output gear, and a second output gear are installed inside the housing; a second gear transmission assembly is installed between the first gear transmission assembly and the second output gear; a clutch mechanism is installed on the second gear transmission assembly; and a gear disengagement mechanism is installed on the second output gear—the drive unit can drive the side trailer to rotate and lift, as well as drive the side trailer to swing, expanding the side trailer's range of motion. Furthermore, the above functions are achieved through a single drive unit, eliminating the need for multiple motors and reducing production costs. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings: The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0016] In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. Example

[0018] like Figure 1 and Figure 2 As shown, this application discloses a side brush swing gearbox, comprising a housing 10, a drive component 20 disposed outside the housing 10 (the drive component 20 being a motor), a first gear transmission assembly 30 disposed inside the housing 10 and connected to the drive component 20, a first output gear 40 and a second output gear 50 meshing with the first gear transmission assembly 30, a second gear transmission assembly 60 disposed between the first gear transmission assembly 30 and the second output gear 50, a clutch mechanism 70 disposed on the second gear transmission assembly, and a gear disengagement mechanism 80 disposed on the second output gear 50. Through the above structural design, the drive component drives the first and second output gears via the first gear transmission assembly. The first output gear transmits the power of the drive component, driving the side brush to rotate and lift, while the second output gear transmits the power of the drive component, driving the side brush to swing. That is, through the first and second output gears, the drive component enables the side brush not only to rotate and clean the floor but also to swing outward relative to the main body of the cleaning robot, thereby allowing the side brush to penetrate into dead-end areas for cleaning.

[0019] like Figure 6 and Figure 7 As shown, the housing 10 includes a first housing and a second housing that can be detachably connected.

[0020] like Figure 2 As shown, the side drag is coaxially arranged with the first output gear and is located outside the housing. Under the drive of the drive unit, the side drag can swing outward relative to the main body of the cleaning robot.

[0021] Specifically, such as Figure 3 As shown, the first gear transmission assembly 30 includes a drive gear 31 mounted on the motor output shaft, a first double gear 32 meshing with the drive gear 31, a first gear 33 meshing with the first double gear 32, and a second double gear 34 meshing with the first gear 33. The motor drives the drive gear, and the drive gear drives the first gear and the second double gear through the first double gear. The first double gear, the first gear, and the second double gear all rotate around their mounting shaft.

[0022] Specifically, such as Figure 3 As shown, the second gear transmission assembly 60 includes a second gear 61 that meshes with the second double gear 34, a third double gear 62 that meshes with the second gear 61, and a third gear 63 that meshes with the third double gear 62 and is movably meshed with the second output gear 50. The second double gear drives the second gear and the third double gear, and the third double gear drives the second output gear through the third gear.

[0023] Specifically, such as Figure 5 and Figure 7 As shown, a clutch mechanism 70 is provided between the third double gear 62 and the third gear 63. The clutch mechanism 70 includes a bracket 71, a rotating shaft 72, and a first spring 73. One end of the bracket is coaxially arranged with the mounting shaft of the third double gear 62, and the other end of the bracket is rotatably mounted with the rotating shaft 72. The third gear 63 is mounted on the rotating shaft 72. The first spring 73 is sleeved on the rotating shaft 72 between the bracket 71 and the third gear 63. A stop block 11 that cooperates with the bracket 71 is provided on the inner wall of the housing 10. The gear disengagement mechanism 80 includes a column 81 that slides along the arc groove 51 on the second output gear 50 and a guide rod 82 that is mounted on the column 81 through a rod head. The guide rod 82 is movably inserted into the gap between two limiting blocks 83. A second spring 84 is sleeved on the guide rod 82 between the limiting blocks 83 and the rod head.

[0024] During operation, when the drive unit rotates forward to unfold, the first output gear 40 is responsible for the rotation and descent of the mop, achieving the cleaning function. The mounting shaft of the second output gear is connected to the main body of the cleaning device. When the unfolding action begins, the sector teeth of the second output gear 50 are located at the initial unfolding position near the first stop 12. As the third double gear 62 drives the third gear 63 to mesh with the second output gear 50, the sector teeth of the second output gear move away from the first stop until the second output gear 50 reaches its maximum boundary point. At this time, the second spring 84 is in its maximum compression state. Under the torque and rotational inertia of the last tooth of the sector gear 50, the mop moves to near the second stop position and stops at the second stop position 13, where it is in a fully extended state. At this time, the third gear 63 disengages from the second output gear 50. When the mop encounters an obstacle, it will reverse at a certain angle and compress the spring. When it does not reach the maximum boundary point of the cam, it will return to the second stop position after the obstacle disappears due to the spring force. When the reversal angle is large and exceeds the maximum boundary point of the cam, the third gear 63 will re-mesh with the second output gear 50 and repeat the extension action. When the drive unit reverses and folds, the first output gear 40 is responsible for the rotation and lifting of the mop. When the folding action begins, the sector teeth of the second output gear 50 are located at the initial folding position near the second stop 13. As the third double gear 62 drives the third gear 63 to mesh with the second output gear 50, the sector teeth of the second output gear 50 move away from the second stop until they reach the maximum boundary point of the second output gear 50. At this time, the second spring 84 is in the maximum compression state. Under the action of the torque and rotational inertia of the last tooth of the sector teeth of the second output gear, it moves to the position near the first stop, stops at the first stop 12, and is in a fully folded state. At this time, the third gear 63 disengages from the second output gear 50. When the mop is rotated in the unfolding direction by external force, the spring will be compressed. When the maximum boundary point of the second output gear is not reached, the external force disappears due to the elasticity of the second spring and the mop will return to the first stop. When the rotation angle is large and exceeds the maximum boundary point of the second output gear, the third gear will re-mesh with the second output gear 50. At this time, the motor will execute the folding command again to start the folding action.

[0025] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, low cost, and strong practicality.
