[0002] With the development of social economy and the improvement of family living standards, household cleaning equipment has gradually entered the era of intelligence and mechanization. Cleaning robots represented by sweeping robots can effectively reduce people's workload in household cleaning, free people from heavy housework and improve their quality of life.
[0003] In order to expand the cleaning range of the sweeping robot, when the sweeping robot is cleaning, the driving motor rotates forward to swing out the cleaning disc for cleaning, and after cleaning, the driving motor rotates reversely to retract the cleaning disc. In order to simplify the internal structure of the existing sweeping robots, the cleaning disc is driven by the same driving source for swinging out, retracting and rotating for cleaning. That is to say, when the cleaning disc is swung outward, the cleaning disc rotates forward, and when the cleaning disc is retracted, the cleaning disc rotates reversely. This results in the direction of the cleaning disc switching between the swinging out and the retracted state. However, there will be a sense of frustration or even jamming when the cleaning disc switches between forward and reverse rotation, and the cleaning disc cannot rotate continuously and stably, affecting the cleaning effect and the service life of the product.

[0027] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.
[0028] Embodiment 1:
[0029] Reference Figure 1 , Figure 1The schematic diagram of the structure of the bidirectional input and unidirectional output mechanism in the first embodiment is shown in FIG. The bidirectional input and unidirectional output mechanism in the present embodiment comprises a driving member 1, a rotating shaft member 2, two unidirectional rotating members 3, a reversing member 4 and an output member 5. The driving end of the driving member 1 is connected to the rotating shaft member 2. The two unidirectional rotating members 3 are respectively connected to the rotating shaft member 2, and the locking rotation directions of the two unidirectional rotating members 3 are opposite. The reversing member 4 is in transmission connection with one of the unidirectional rotating members 3, and the output member 5 is in transmission connection with the reversing member 4 and the other unidirectional rotating member 3. The driving member 1 drives the rotating shaft member 2 to rotate forward in the forward direction, and the rotating shaft member 2 rotates forward to drive the other unidirectional rotating member 3 to rotate forward, and the other unidirectional rotating member 3 rotates forward to drive the output member 5 to rotate in the first direction. The driving member 1 drives the rotating shaft member 2 to rotate in the reverse direction, and the rotating shaft member 2 rotates in the reverse direction to drive one of the unidirectional rotating members 3 to rotate in the reverse direction, and the one of the unidirectional rotating members 3 rotates in the reverse direction through the reversing member 4 to drive the output member 5 to rotate in the first direction.
[0030] The bidirectional input and unidirectional output mechanism in this embodiment can be applied to a sweeping robot, where the cleaning turntable is connected to the output member 5, and the output member 5 rotates to drive the cleaning turntable to rotate in the same direction for cleaning. The driving member 1 is also connected to the external swing mechanism. When the driving member 1 is driven in the forward direction, the external swing mechanism swings the cleaning turntable outward to the outside of the housing of the sweeping robot for cleaning. When the driving member 1 is driven in the reverse direction, the external swing mechanism retracts the cleaning turntable into the housing of the sweeping robot. That is, when the driving member 1 is driven in the forward direction, the driving member 1 drives the rotating shaft member 2 to rotate forward, and the forward rotation of the rotating shaft member 2 drives the other unidirectional rotating member 3 to rotate forward. At this time, one of the unidirectional rotating members 3 does not rotate forward synchronously with the rotating shaft member 2, and the forward rotation of the other unidirectional rotating member 3 drives the output member 5 to rotate in the first direction through the reversing member 4, and the output member 5 drives the cleaning turntable to rotate in the first direction. When the driving member 1 is driven in reverse, the driving member 1 drives the rotating shaft member 2 to rotate in reverse, and the reverse rotation of the rotating shaft member 2 drives one of the one-way rotating members 3 to rotate in reverse. At this time, the other one-way rotating member 3 does not rotate in reverse synchronously with the rotating shaft member 2. The reverse rotation of one of the one-way rotating members 3 drives the output member 5 to rotate in the first direction. That is to say, no matter whether the driving member 1 is driven forward or reverse, the output member 5 finally rotates in the first direction, that is, the cleaning turntable rotates in the first direction. In this way, when the driving member 1 switches between forward drive and reverse drive, the output member 5 can always keep rotating in one direction, and the rotation output by the output member 5 is continuous and stable. At the same time, when the driving member 1 switches between forward and reverse directions, the output member 5 rotates smoothly without any sense of jerkiness, thereby improving the cleaning effect of the sweeping robot.
[0031] Re-reference Figure 1Preferably, the one-way rotating member 3 includes a one-way bearing and a rotating gear, the one-way bearing is sleeved outside the rotating shaft member 2, the rotating gear is fixedly sleeved outside the one-way bearing, the locking rotation directions of the two one-way bearings are opposite, one of the rotating gears is meshed and connected with the reversing member 4, and the other rotating gear is meshed and connected with the output member 5. In specific application, the rotating shaft member 2 in this embodiment is a rotating shaft 21, the inner rings of the two one-way bearings are fixedly sleeved outside the rotating shaft 21, and the rotating gears are fixedly sleeved outside the outer rings of the one-way bearings. It can be understood that when the driving member 1 is driven in the forward direction: the driving member 1 drives the rotating shaft member 2 to rotate in the forward direction, and because the locking rotation directions of the two one-way bearings are opposite, when the rotating shaft member 2 rotates in the forward direction, the inner ring and outer ring of the other one-way bearing both rotate in the forward direction following the rotating shaft member 2, and the inner ring of one of the one-way bearings rotates in the forward direction following the rotating shaft member 2, and the outer ring of one of the one-way bearings does not rotate in the forward direction following the rotating shaft member 2, that is, one of the one-way bearings is idling at this time. When the other one-way bearing rotates forward, the rotating gear fixed to its outer ring can drive the output member 5 to rotate in the opposite direction, and the output member 5 rotates in the opposite direction to drive the reversing member 4 to rotate forward. In this embodiment, the reversing member 4 is a reversing gear. The forward rotation of the reversing member 4 will drive the outer ring of one of the one-way bearings and the rotating gear fixed outside the outer ring to rotate in the opposite direction. At this time, it does not affect the idling of one of the one-way bearings. The output member 5 rotates in the opposite direction to drive the cleaning turntable to rotate and clean. When the driving member 1 drives in the opposite direction: the driving member 1 drives the rotating shaft member 2 to rotate in the opposite direction, the inner ring and outer ring of one of the one-way bearings both rotate in the opposite direction with the rotating shaft member 2, and the inner ring of the other one-way bearing rotates in the opposite direction with the rotating shaft member 2, and the outer ring of the other one-way bearing does not rotate in the opposite direction with the rotating shaft member 2, that is, the other one-way shaft is idling at this time. When one of the one-way bearings rotates in the reverse direction, the rotating gear fixed to its outer ring can drive the reversing member 4 to rotate in the forward direction, and the forward rotation of the reversing member 4 drives the output member 5 to rotate in the reverse direction, and the reverse rotation of the output member 5 drives the cleaning turntable to rotate and clean, and the reverse rotation of the output member 5 will drive the outer ring of the other one-way bearing and the rotating gear fixed outside the outer ring to rotate in the forward direction, and at this time, it does not affect the idling of the other one-way bearing. It can be seen that no matter whether the driving member 1 is driven in the forward direction or the reverse direction, the power output by the output member 5 is in the same direction, that is, the first direction described in the present application, and the first direction in this embodiment is the reverse rotation direction. Of course, in other embodiments, the first direction can also be the forward rotation direction, which can be achieved by setting two reversing members 4 between the output member 5 and one of the one-way rotating members 3, and setting one reversing member 4 between the output member 5 and the other one-way rotating member 3. Of course, the number of reversing members 4 can also be set according to actual needs. Specifically, the central axes of the two one-way bearings are arranged colinearly with the axis of the rotating shaft 2, that is, the two one-way bearings are arranged coaxially and are arranged on the same rotating shaft 21, which improves the accuracy and stability of the transmission. Of course, in other embodiments, the one-way rotating member 3 can also be other structures such as a one-way locking mechanism, which will not be repeated here.
[0032] Re-reference Figure 1 Preferably, the bidirectional input and unidirectional output mechanism further includes a transmission member 6, and the driving member 1 drives the rotating shaft member 2 to rotate through the transmission member 6. In specific applications, the transmission member 6 includes a transmission shaft 61 and a transmission gear 62, the transmission shaft 61 is connected to the driving end of the driving member 1, and the transmission gear 62 is fixedly sleeved outside the transmission shaft 61, and the rotating shaft member 2 further includes a rotating shaft gear 22, the rotating shaft gear 22 is fixedly sleeved outside the rotating shaft 21, and the transmission gear 62 is meshed and connected with the rotating shaft gear 22. It should be specially noted that the forward and reverse directions described in the present application have no specific limiting function, and are only used to express whether the rotation directions of the two are in the same direction or in the opposite direction. Specifically, when the number of transmission gears 62 is one, the forward driving of the driving member 1 through the transmission member 6 will cause the rotating shaft member 2 to rotate in the opposite direction. When a transmission member 6 is provided with two mutually meshing transmission gears 62, that is, a gear set is formed, at this time, the forward driving of the driving member 1 through the transmission member 6 will cause the rotating shaft member 2 to rotate forward, that is, the transmission member 6 is equivalent to a transmission gear set, which can be set according to actual needs, so as to adjust the rotation direction of the rotating shaft member 2, and accelerate or decelerate the rotation speed of the driving member 1. Specifically, the driving member 1 is a motor. The axis of the driving shaft of the driving member 1 is parallel to the axis of the rotating shaft 21.
[0033] Re-reference Figure 1 Preferably, the output member 5 includes an output shaft 51 and a gear shaft 52, the gear shaft 52 is meshed with the reversing member 4 and the rotating gear outside the other one-way bearing, respectively, and the output shaft 51 is connected to the gear shaft 52. Through the setting of the gear shaft 52, the gear shaft 52 can be meshed with the reversing member 4 and the rotating gear outside the other one-way bearing at the same time, so that the meshing between the gears is tighter, the continuity and stability of the power output are improved, and at the same time, it is smoother when switching between forward and reverse rotation without frustration. Further, the output member 5 also includes an output transmission member 55, and the output transmission member 55 is connected to the output shaft 51. In specific application, the output transmission member 55 is connected to the cleaning turntable, and the output shaft 51 rotates through the output transmission member 55 for power transmission, thereby driving the cleaning turntable to rotate. In this embodiment, the output transmission member 55 is a transmission gear set, which can be set according to actual needs to adjust the speed or position of the cleaning turntable. Of course, in other embodiments, the output transmission member 55 can also be not set, and the cleaning turntable can be directly fixedly sleeved outside the output shaft 51.
[0034] Embodiment 2:
[0035] Reference Figure 2 , Figure 2The schematic diagram of the structure of the bidirectional input and unidirectional output mechanism in the second embodiment is that the bidirectional input and unidirectional output mechanism in this embodiment is different from that in the first embodiment in that the output member 5 in this embodiment includes an output shaft 51, a first output wheel 53 and a second output wheel 54, the first output wheel 53 and the second output wheel 54 are respectively fixedly sleeved outside the output shaft 51, the first output wheel 53 is meshedly connected with the reversing member 4, and the second output wheel 54 is meshedly connected with the rotating gear outside another one-way bearing. That is, two output wheels are used in this embodiment to replace the gear shaft 52 in the first embodiment, and the volume of the output wheel is smaller than that of the gear shaft 52, which is convenient for the internal layout of the sweeping robot and reduces the manufacturing cost.
[0036] Embodiment three:
[0037] Reference Figure 3 , Figure 3 This is a structural diagram of the bidirectional input and unidirectional output mechanism in Example 3. The difference between the bidirectional input and unidirectional output mechanism in this embodiment and that in Example 1 is that the axis of the driving shaft of the driving member 1 in this embodiment is colinear with the axis of the rotating shaft member 2. That is to say, this embodiment does not have a transmission member 6, but directly connects the rotating shaft 21 to the driving shaft of the motor, that is, at this time, the rotating shaft 21 is equivalent to the driving shaft of the motor, which further simplifies the internal structure, makes the structural design more flexible, and facilitates the layout optimization of the overall internal structural design of the sweeping robot.
[0038] Embodiment 4:
[0039] Reference Figure 4 , Figure 4 : is a structural diagram of the bidirectional input and unidirectional output mechanism in the fourth embodiment. The difference between the bidirectional input and unidirectional output mechanism in this embodiment and that in the first embodiment is that the axis of the driving shaft of the driving member 1 in this embodiment is perpendicular to the axis of the rotating shaft member 2. In this embodiment, the transmission gear 62 of the transmission member 6 is a bevel gear, and the rotating shaft gear 22 is also a bevel gear, so that the driving shaft of the driving member 1 and the rotating shaft member 2 can be arranged vertically to adapt to the layout requirements of different internal structures of the sweeping robot, and the structural design is more flexible.
[0040] Embodiment five:
[0041] Reference Figure 5 , Figure 5The schematic diagram of the structure of the bidirectional input and unidirectional output mechanism in the fifth embodiment is shown in FIG. The bidirectional input and unidirectional output mechanism in the present embodiment comprises a driving member 1, a rotating shaft member 2, two unidirectional rotating members 3, a reversing member 4 and an output member 5. The driving end of the driving member 1 is connected to the rotating shaft member 2. The rotating shaft member 2 is respectively connected to the reversing member 4 and one of the unidirectional rotating members 3 in a transmission connection. The reversing member 4 is connected to the other unidirectional rotating member 3 in a transmission connection. The two unidirectional rotating members 3 are respectively connected to the output member 5, and the locking rotation directions of the two unidirectional rotating members 3 are the same. The driving member 1 drives the rotating shaft member 2 to rotate forward in a forward direction. The rotating shaft member 2 rotates forward to drive one of the unidirectional rotating members 3 to rotate in the reverse direction. The reverse rotation of the one unidirectional rotating member 3 drives the output member 5 to rotate in the first direction. The driving member 1 drives the rotating shaft member 2 to rotate in the reverse direction. The reverse rotation of the rotating shaft member 2 drives the other unidirectional rotating member 3 to rotate in the reverse direction through the reversing member 4. The reverse rotation of the other unidirectional rotating member 3 drives the output member 5 to rotate in the first direction. In specific applications, the one-way rotating member 3 in this embodiment is the same as the one-way rotating member 3 in embodiment 1. The rotating shaft member 2 in this embodiment includes a rotating shaft 21 and two rotating shaft gears 22, one of which is meshedly connected to the reversing member 4, and the other rotating shaft gear 22 is meshedly connected to one of the one-way rotating members 3. When the driving member 1 is driven in the forward direction, the driving member 1 drives the rotating shaft 21 and the two rotating shaft gears 22 to rotate in the forward direction, and the other rotating shaft gear 22 rotates in the forward direction to drive the outer ring, inner ring and rotating gear fixedly sleeved outside the outer ring of one of its one-way bearings to rotate in the reverse direction, thereby driving the output member 5 to rotate in the reverse direction, and the output member 5 rotates in the reverse direction to drive the inner ring of the other one-way bearing to rotate in the reverse direction, but does not drive the outer ring of the other one-way bearing to rotate in the reverse direction, that is, the inner ring of the other one-way bearing rotates idly at this time, and at this time, since the forward rotation of one of its rotating shaft gears 22 drives the reversing member 4 to rotate in the reverse direction, the reversing member 4 rotates in the reverse direction to drive the outer ring of the other one-way bearing and the rotating gear fixedly sleeved outside the outer ring to rotate in the forward direction, in short, when the driving member 1 is driven in the forward direction, the power is transmitted to the output member 5 through one of its one-way bearings, and the other one-way bearing rotates idly. The process and principle of the reverse drive of the driving member 1 are similar to those of the forward drive, and will not be repeated here.
[0042] In summary, when the driving member is driven in the forward direction, the driving member drives the shaft member to rotate in the forward direction, and the forward rotation of the shaft member drives the other one-way rotating member to rotate in the forward direction. At this time, one of the one-way rotating members does not rotate synchronously with the shaft member in the forward direction, and the forward rotation of the other one-way rotating member drives the output member to rotate in the first direction through the reversing member, and the output member rotates in the first direction to output power. When the driving member is driven in the reverse direction, the driving member drives the shaft member to rotate in the reverse direction, and the reverse rotation of the shaft member drives one of the one-way rotating members to rotate in the reverse direction. At this time, the other one-way rotating member does not rotate synchronously with the shaft member in the reverse direction, and the reverse rotation of the one-way rotating member drives the output member to rotate in the first direction, and the output member still rotates in the first direction to output power. In this way, no matter whether the driving member is driven forward or reverse, the output member will finally rotate in the first direction to output power, and when the driving member switches between forward drive and reverse drive, the output member can always keep rotating in the first direction. The rotational force output by the output member is continuous and stable, and the output member rotates smoothly without any lag when the driving member switches between forward and reverse directions, thereby improving the cleaning effect of the sweeping robot, reducing component damage caused by switching jams, and extending the service life.
