Description

Technical Field

[0001] The utility model relates to the field of mopping machines, in particular to a mopping cloth outward swing lifting mechanism and the mopping machine. Background Art

[0002] With the improvement of people's living standards, smart appliances are becoming more and more widely integrated into people's lives and work environments. Among them, sweeping robots are one of the most widely used ones. They can intelligently perform activities such as sweeping the floor, greatly reducing people's labor intensity and saving labor costs.

[0003] In a sweeping machine, one of the core modules is its mopping module. The mopping module is a device that performs mopping. In existing mopping machine products, the mopping module is usually set at an inner position at the bottom of the mopping machine. When the mopping machine is mopping, when the mopping machine encounters a mopping position at a corner, due to the spatial obstruction of the main shell of the mopping machine, the mopping module usually finds it difficult to reach the mopping position at the corner, resulting in difficulty in achieving the automatic mopping function at the corner. In order to solve this problem, some mopping machine products have added a function for swinging the mopping module outward, so that the mopping machine swings its mopping module outward when encountering a corner, and then uses the outward-swinging mopping module to mop the corner. However, due to structural and design limitations, the external swing mechanism of existing mopping machines generally adopts a rotary external swing mechanism. This type of rotary external swing mechanism has the problem of occupying a large space, easily forming position interference with other components, and is inconvenient to use. In addition, the existing rotary external swing mechanism has the problems of complex structure, insufficient performance reliability and stability, high implementation cost, and poor user experience.

[0004] Therefore, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0044] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present utility model can be combined interactively without conflicting with each other, refer to Figures 1-13 .

[0045] A mop cloth outward swing lifting mechanism for a mopping machine includes a floating mounting seat 91, an outward swing guide groove 911 is provided on the floating mounting seat 91, an outward swing mounting plate 92 that can move in the outward swing guide groove 911 is provided in the outward swing guide groove 911, an outward swing mounting plate 92 is provided with an outward swing rack 93, an outward swing drive motor 94 is provided on the floating mounting seat 91, an outward swing gear 95 is provided at the output end of the outward swing drive motor 94, and the outward swing gear 95 is connected to the outward swing rack 93. They are meshed with each other, and a plurality of floating mounting holes 912 are provided on the floating mounting seat 91. A buffer spring mounting hole 913 is provided at the outer end of the floating mounting seat 91. A buffer spring is provided in the buffer spring mounting hole 913. A mop lifting module is provided on the outward swing mounting plate 92. The outward swing drive motor 94 can drive the outward swing mounting plate 92 to move in the outward swing guide groove 911 through the outward swing gear 95 and the outward swing rack 93 and synchronously drive the mop lifting module to perform outward swing movement.

[0046] In actual use, when the mopping machine needs to mop corners, the outward swing drive motor 94 drives the outward swing gear 95 to rotate. The outward swing gear 95 drives the outward swing mounting plate 92 to slide in the outward swing guide groove 911 through the outward swing rack 93 and drives the mop lifting module on the outward swing mounting plate 92 to swing outward. When the mop lifting module is driven outward to a preset position, the outward swing drive motor 95 stops rotating. At this time, the mop lifting module lifts and lowers the mop to mop the floor, which can be used to mop corners. This outward swing mechanism has a simple structure, low implementation cost, more stable performance, more reliable operation, and occupies less space. The floating mounting seat 91 is connected to the housing of the mopping machine by screws passing through its floating mounting hole 913. The screw only limits the position of the floating mount 91 along its axis. The floating mount 91 is movable along the length of the floating mounting slot 913, providing a horizontal floating function. This floating function prevents the swing mechanism from colliding with obstacles during the swing process, thereby protecting the mop and the obstacle. Furthermore, the buffer spring provides an elastic buffer against obstacles, further mitigating impact forces and protecting the product.

[0047] In this embodiment, a middle slot 910 is provided in the middle position of the floating mounting seat 91, and the outward swing guide slot 911 is provided on the inner side wall of the middle slot 910; the middle slot 910 is provided for the mop lifting module to lift and lower the mop floor, providing an air avoidance function.

[0048] In this embodiment, the floating mounting hole 912 is an elongated mounting hole; the output shaft of the outward swing drive motor 94 is provided with a reducer 96, and the outward swing gear 95 is provided on the output shaft of the reducer 96; the outward swing rack 93 and the outward swing mounting plate 92 are an integrally formed part. In some other embodiments, the outward swing rack 93 and the outward swing mounting plate 92 may also adopt a split structure.

[0049] In some embodiments, the mop lifting module includes a gear box 1 and a drive motor 2, and a first intermediate rotating shaft 31, a second intermediate rotating shaft 32 and a drive shaft 33 are installed inside the gear box 1, a first rotating gear 311 and a second rotating gear 312 are provided on the first intermediate rotating shaft 31, a third rotating gear 321 and a fourth rotating gear 322 are provided on the second intermediate rotating shaft 32, a drive gear 331 is provided on the drive shaft 33, and an output gear 21 is provided on the output shaft of the drive motor 2, the output gear 21 and the first rotating gear 311 are meshed with each other, the second rotating gear 312 and the third rotating gear 321 are meshed with each other, and the fourth rotating gear 322 and the drive gear 331 are meshed with each other. The drive motor 2 can be engaged with the output gear 21, the first rotating gear 311, The second rotating gear 312, the third rotating gear 321, the fourth rotating gear 322 and the driving gear 331 drive the driving shaft 33 to rotate. A damping sleeve 4 is provided at the bottom of the gear box 1. A lifting sleeve 5 is provided inside the damping sleeve 4. The outer wall of the lifting sleeve 5 is in contact with the damping sleeve 4. The lifting sleeve 5 is used to connect the mop. An internal threaded sleeve 6 is fixedly provided inside the lifting sleeve 5. The inner wall of the internal threaded sleeve 6 is provided with an internal thread 61. A lifting drive sleeve 7 is provided at the lower end of the driving shaft 33. The lower end of the lifting drive sleeve 7 extends into the interior of the internal threaded sleeve 6 and the outer wall of the part extending into the interior of the internal threaded sleeve 6 is provided with an external thread 71. The external thread 71 cooperates with the internal thread 61 and makes the internal thread sleeve 6 and the lifting drive sleeve 7 threadedly connected.

[0050] Specifically, when in use, the lifting sleeve 5 is used to connect the mop. After the sweeper starts working, when it is necessary to perform the lifting task of the mop, the driving motor 2 drives the first rotating gear 311 to rotate through the output gear 21, the first rotating gear 311 drives the second rotating gear 312 to rotate, the second rotating gear 312 drives the third rotating gear 321 to rotate, the third rotating gear 322 drives the fourth rotating gear 322 to rotate, the fourth rotating gear 322 drives the driving gear 331 to rotate, the driving gear 331 drives the driving shaft 33 to rotate, and the driving shaft 33 drives the lifting driving sleeve 7 to rotate. There is a damping effect between the damping sleeve 4 and the lifting sleeve 5. Therefore, when the lifting drive sleeve 7 is rotating, the lifting sleeve 5 does not rotate synchronously with the lifting drive sleeve 7. There is relative rotation between the two. At this time, through the matching structure of the external thread 71 and the internal thread 61, the relative lifting movement of the internal thread sleeve 6 and the lifting drive sleeve 7 can be achieved. Since the internal thread sleeve 6 is fixedly installed inside the lifting sleeve 5, when the internal thread sleeve 6 is lifted and moved, the lifting sleeve 5 is lifted and moved synchronously, so the mop connected to the lifting sleeve 5 is also lifted and moved.

[0051] In some embodiments, the internally threaded sleeve 6 is provided with an internally threaded stopper 62 on its inner wall. The internally threaded stopper 62 is used to limit the rotation of the external thread 71 within the internally threaded sleeve 61. When the lifting sleeve 5 descends to a preset position, the internally threaded stopper 62 and one end of the external thread 71 mutually limit each other to limit relative rotation between the internally threaded sleeve 6 and the lifting drive sleeve 7. At this time, the lifting sleeve 5 descends to its lowest point, and the mop is at the mopping height. Due to the limiting effect of the internally threaded stopper 62, the lifting drive sleeve 7 is fixed to the lifting sleeve 5 and the internally threaded sleeve 6 and prevents relative rotation. At this time, the drive shaft 32 continues to drive the lifting drive sleeve 7 to rotate, and the lifting drive sleeve 7 drives the internally threaded sleeve 6 and the lifting sleeve 5 to rotate after overcoming the damping effect of the damping sleeve 4. During the rotation, the lifting sleeve 5 drives the mop to rotate, thereby achieving the mopping function.

[0052] In some embodiments, a rising position limit block 54 is provided at the bottom of the interior of the lifting sleeve 5, and a bottom limit block 72 is provided at the bottom of the lifting drive sleeve 7. The bottom limit block 72 is adapted to the rising position limit block 54. When the lifting sleeve 5 rises to a preset position, the rising position limit block 54 and the bottom limit block 72 are mutually limited to restrict relative rotation between the lifting sleeve 5 and the lifting drive sleeve 7. Due to the mutual limiting effect of the bottom limit block 72 and the rising position limit block 54, after the lifting sleeve 5 rises to the highest position, the mop rises to a position off the ground, and the lifting drive sleeve 7 and the lifting sleeve 5 are fixed to each other and do not rotate relative to each other. At this time, the drive shaft 32 continues to drive the lifting drive sleeve 7 to rotate, and the lifting drive sleeve 7 drives the lifting sleeve 5 to rotate after overcoming the damping effect of the damping sleeve 4.

[0053] In some embodiments, a through slot 41 extending from inside to outside is provided on the side of the damping sleeve 4. A damping spring 42 is provided in the through slot 41. The inner wall of the damping spring 42 is in frictional contact with the outer wall of the lifting sleeve 5 and forms a damping force on the lifting sleeve 5. Specifically, in this embodiment, the damping spring 42 includes a central contact portion and elastic portions on both sides. The contact portion contacts the outer wall of the lifting sleeve 5. The elastic portion provides a tensioning elastic force to the contact portion. By adjusting the elastic force of the elastic portion, the contact pressure between the contact portion and the lifting sleeve 5 can be adjusted, and thus the damping value can be adjusted. In specific implementation, a suitable damping value can be set as needed. In this embodiment, the damping sleeve 4 and the outward swing mounting plate 92 are integrally formed. In other embodiments, the damping sleeve 4 and the outward swing mounting plate 92 can also be designed as a split part.

[0054] In some embodiments, a damping sleeve connecting buckle 43 is provided on the damping sleeve 4, and a damping sleeve connecting card 13 adapted for the damping sleeve connecting buckle 43 is provided on the gear box 1. The damping sleeve connecting buckle 43 is buckled on the damping sleeve connecting card 13 and the damping sleeve 4 is fixedly installed on the bottom of the gear box 1; the gear box 1 includes an upper box body 11 and a lower box body 12, and the outer wall of the upper box body 11 is provided with a gear box connecting buckle 111, and the outer wall of the lower box body 12 is provided with a gear box connecting card 121 that cooperates with the gear box connecting buckle 111, and the gear box connecting card 121 is clamped on the gear box connecting buckle 111 and the upper box body 11 and the lower box body 12 are fixedly connected to form the gear box 1. The gearbox 1 formed by the upper box body 11 and the lower box body 12 has a gearbox inner cavity, and the output gear 21, the first rotating gear 311, the second rotating gear 312, the third rotating gear 321, the fourth rotating gear 322, the driving gear 331, the first intermediate rotating shaft 31, the second intermediate rotating shaft 32 and the driving shaft 33 are all arranged in the gearbox inner cavity.

[0055] In some embodiments, the lifting sleeve 5 includes an outer sleeve 51 and an inner sleeve 52 disposed within the outer sleeve 51. The outer sleeve 51 and the inner sleeve 52 are connected at the bottom via a bottom connecting plate 53. A sandwich cavity 50 is formed between the inner wall of the outer sleeve 51 and the outer wall of the inner sleeve 52. The internally threaded sleeve 6 is disposed on the inner wall of the outer sleeve 51. The lower portion of the lifting drive sleeve 7 extends into the sandwich cavity 50, and the inner sleeve 52 extends into the lower cavity of the lifting drive sleeve 7. Specifically, the inner sleeve 52 has an internal connecting hole 59 for connecting to the mounting rod of the mop.
