Instruction Manual Pages 4 / 9 6 CN 121465442 A

[0034] Example 1 Please refer to Figure 1. A preferred embodiment of the present invention shows a cleaning mechanism suitable for installation on the body of a cleaning device to move with the body and clean the surface to be cleaned. In this embodiment, the cleaning device can be a sweeper, mop, sweeper-mop combo, floor scrubber, etc., and the surface to be cleaned can be a floor, wall, tabletop, sofa, shop window, etc.

[0035] The cleaning mechanism includes a base 1 connected to the body, a cleaning component 3 connected to the base 1, and a second drive component 5 connected to the cleaning component 3. When the cleaning device cleans the surface to be cleaned, the second drive component 5 drives the cleaning component 3 to rotate to clean the surface to be cleaned, and the cleaning device moves to drive the body and the cleaning component 3 to move, thereby realizing the movable cleaning of the surface to be cleaned.

[0036] In the prior art, the cleaning component 100 on the cleaning equipment is usually fixed in position relative to the machine body. Due to the limitations of the machine body, the cleaning component 100 has certain area limitations when performing cleaning work. For example, the cleaning component 100 cannot clean the corners of the surface to be cleaned, resulting in poor cleaning effect.

[0037] In order to solve the above problems, in this embodiment, please refer to FIG1. ​​The cleaning component 3 includes the cleaning component 100. The cleaning mechanism also includes a first driving component 4. The first driving component 4 is adapted to drive the cleaning component 100 to rotate relative to the base 1, so that the cleaning component 100 has an inward position or an outward position, thereby achieving a better cleaning effect of the cleaning component 100.

[0038] Specifically, the first driving component 4 includes a first driving component 43, a transmission component 41 connected to the first driving component 43, a swing component 42 cooperating with the transmission component 41, and an actuator 421 rotatably disposed on the rotating shaft 2. Among them, the first driving component 43 is adapted to drive the cleaning component 100 to rotate relative to the base 1, so that the cleaning component 100 has an inward position or an outward position, thereby achieving a better cleaning effect of the cleaning component 100.The first driving member 43 can rotate in a first direction or a second direction according to the control signal. The swing member 42 is rotatably mounted on the base 1, and the cleaning member 100 is rotatably connected to the swing member 42 via the rotating shaft 2 and the base 1. The swing member 42 is connected to the cleaning member, and the two ends of the actuator 421 act on the swing member 42 and the transmission member 41 respectively. When the swing member 42 cooperates with the transmission member 41, it is driven by the transmission member 41 to rotate, thereby driving the cleaning member 100 to switch between the inward position (see Figure 3) and the outward position (see Figure 2). When the cleaning member 100 is in normal cleaning operation (no need to clean the corners), the cleaning member 100 can clean the surface to be cleaned simply by being in the inward position. When the cleaning equipment needs to clean the corners of the surface to be cleaned, the cleaning member 100 needs to move from the inward position to the outward position to realize the cleaning equipment's treatment of the corners of the surface to be cleaned. It should be noted that in this embodiment, the cleaning component 100 is a wiping cloth tray, and the edge of the wiping cloth tray protrudes beyond the edge of the swing component 42 to achieve a better cleaning effect on the surface to be cleaned.

[0039] In one case, the transmission component 41 transmits the driving force of the first driving component 43 toward the first direction to the actuator 421, so that the transmission component 421 rotates to drive the swing component 42 to rotate, thereby causing the cleaning component 100 to follow the swing component 42 to rotate toward the second direction, and then move from the inward position to the outward position. It should be noted that in this embodiment, during the process of the cleaning component switching from the inward position to the outward position, the actuator 421 stores energy under the driving force of the transmission component 41 and drives the swing component 42 to rotate; when the driving force applied to the transmission component 41 is removed, the actuator 421 releases the stored energy to drive the swing component 42 to continue swinging toward the outward position.

[0040] Specifically, the actuator 421 includes a sleeve portion 4211 sleeved on the rotating shaft 2 and a first abutting end 4212 and a second abutting end 4213 disposed around the sleeve portion 4211. The first abutting end 4212 abuts against the transmission member 41, and the second abutting end 4213 abuts against the swing member 42, so that the first abutting end 4212 can rotate around the sleeve portion 4211 under the driving force of the transmission member 41 in the second direction, thereby allowing the second abutting end 4213 to abut against the rotation of the swing member 42, and thus allowing the cleaning member to move from the inward position to the outward position.

[0041] More specifically, the transmission member 41 is provided with a retaining groove 411. The swing member 42 also includes a first pressing portion 4221. The first abutting end 4212 is adapted to be retained in the retaining groove 41, and the second abutting end 4213 cooperates with the first pressing portion 4221 to abut. When the first driving member 43 rotates in the first direction, the first driving member 43 drives the transmission member 41 to rotate in the second direction. (See instruction manual, page 5 / 9, CN 121465442 A)The groove 411 abuts against the first abutting end 4212, thereby driving the second abutting end 4213 to rotate in the second direction, so that the second abutting end 4213 abuts against the first pressing part 4221, thereby driving the entire swing member 42 to rotate in the second direction, and then driving the cleaning member to move from the inward position to the outward position.

[0042] As described above, referring to FIG9 and FIG10, the swing member 42 also includes a second pressing part 4222 and a support part 4223 respectively disposed on both sides of the first pressing part 4221. The cleaning member 100 is located below the support part 4223 and is connected to the support part 4223. The transmission member 41 also includes a stop portion 44 that abuts against the second stop portion 4222. When the transmission member 41 is driven by the first driving member 43 in the second direction, it rotates in the first direction, thereby driving the stop portion 44 to rotate around the rotating shaft 2 in the first direction, so as to support the second stop portion 4222 and drive the swing member 42 to rotate, so that the cleaning member moves from the outward expansion position to the inward contraction position. It is worth noting that in this embodiment, whether the cleaning member moves from the outward expansion position to the inward contraction position or from the inward contraction position to the outward expansion position, the second stop portion 4222 always abuts against the stop portion 44.

[0043] It should be noted that in this embodiment, the actuator 421 is an elastic member, preferably a torsion spring. The torsion spring can maintain the stability of the transmission member 41 and the swing member 42 when the cleaning member 100 switches between the outward expansion position and the inward contraction position. In this embodiment, there is one torsion spring. In other embodiments, the torsion spring can also be set to other numbers, such as two torsion springs. In this embodiment, the torsion spring has an open end and a closed end. The open end serves as the first abutment end 4212, which is held in the holding groove 411. The closed end serves as the second abutment end 4213, which cooperates with the first pressing part 4221 of the swing member. This allows the transmission member 41 to transmit the driving force of the first driving member 43 to the first abutment end 4212. When the first driving member 43 overcomes the elastic force of the torsion spring, it drives the closed end to rotate around the rotating shaft 2 and press against the first pressing part 4221 of the swing member 42, causing the swing member 42 to drive the cleaning member 100 to rotate. In other embodiments, the actuator 421 can also be configured with other structures, such as a structure consisting of two connecting plates connected and rotating around the rotating shaft 2. As long as the above effect can be achieved, its specific structure is not specifically limited here.

[0044] In this embodiment, the purpose of setting the actuator 421 as an elastic element is as follows: On the one hand, during the operation of the cleaning mechanism following the machine body, the cleaning mechanism may be subjected to external forces. For example, when the cleaning mechanism is squeezed by an obstacle in the outward expansion position or the position between the inward expansion position and the outward expansion position, the elastic element can play a certain buffering role for the cleaning component 3, preventing the cleaning component 3 from colliding with the base 1 and causing damage when subjected to external forces; at the same time, due to the setting of the elastic element, the elasticityThe force will always resist the first pressing part, so that the entire cleaning part 100 can always resist the corner and complete the cleaning of the corner, without the cleaning part 100 changing to the inward position after being squeezed by external force; on the other hand, whether the cleaning part 100 rotates from the outward position to the inward position or from the inward position to the outward position, the cleaning part 100 is subjected to frictional force opposite to the rotation direction of the swinging part during the transmission process. The elastic force of the elastic member can offset part of the frictional force generated by the cleaning part 100 when rotating, so as to improve the stability of the cleaning mechanism.

[0045] Please refer to Figures 5 and 7. In this embodiment, the transmission member 41 further includes a gear part 412 and a connecting part 413 connected to the gear part 412. The gear part 412 is adapted to be connected to the first driving member 43. The abutting part 44 is disposed on the connecting part 413. The first driving member 43 drives the gear part 412 to rotate, thereby driving the connecting part 413 to rotate and driving the first abutting end 4212 to rotate, so that the cleaning member 100 switches from the inward position to the outward position, or drives the connecting part 413 to rotate and drives the abutting part 44 to rotate.

[0046] When the first driving member 43 drives the gear part 412 to rotate, it can drive the connecting part 413 to rotate, thereby driving the first abutting end 4212 to rotate, thereby driving the second abutting end 4213 to press against the first pressing part 4221, and then driving the cleaning member 100 to move from the outward expansion position to the inward contraction position; or, when the first driving member 43 drives the gear part 412 to rotate, it can drive the connecting part 413 to rotate, thereby driving the abutting part 44 to rotate, so that the abutting part 44 abuts against the second pressing part 4222, thereby driving the entire swing member 42 to rotate, and then driving the cleaning member to move from the inward contraction position to the outward expansion position.

[0047] Further, the transmission member 41 also includes a first gear 414 connected to the first driving member 43 and a second gear 415 meshing with the first gear 414. The second gear 415 includes the aforementioned gear part 412, connecting part 413 and abutting part 44. In this embodiment, the second gear 415 is an incomplete gear, and its circumference is set only to ensure that the cleaning component 100 can switch between the inward and outward positions. The purpose of setting the second gear 415 as an incomplete gear is to reduce the space occupied by the second gear 415. In other embodiments, the second gear 415 can also be set as a complete gear, which is not specifically limited here.

[0048] As described above, in order to make reasonable use of space and reduce the volume of the entire cleaning mechanism, in this embodiment, referring to FIG4 and FIG8, the sleeve part 421 includes an upper half end 4214, a lower half end 4215 connected to the upper half end 4214, and a space formed between the upper half end 4214 and the lower half end 4215; the swinging component 42 includes an upper end end 4224 and a lower end end 4225 connected to the upper end end 4224, so thatThe upper half 4214 and lower half 4215 of the actuator 421 are staggered with the upper end 4224 and lower end 4225 of the swing member 42, so that the actuator 421 and the swing member 42 can be stably connected by the rotating shaft 2, and the structure of the actuator 421, the swing member 42 and the base 1 can be more compact.

[0049] Referring to FIG4, in this application, the cleaning mechanism also includes a bearing 54 disposed between the swing member 42 and the rotating shaft 2, and a bushing 55 disposed outside the bearing 54. The main function of the bushing 55 is to reduce the wear generated by the connecting part 413 of the second gear 415 when rotating around the rotating shaft 2, while the bearing 54 can reduce the friction generated by the swing member 42 when rotating around the rotating shaft 2, so as to achieve the effect of saving effort for the first driving member 43.

[0050] Referring to FIG4, the cleaning mechanism also includes a fixing component 6, which is adapted to fix the rotating shaft 2 and the base 1. In this embodiment, the fixing component 6 includes a first fixing member 61 and a second fixing member 62 respectively disposed at both ends of the rotating shaft 2. The base 1 is provided with a first groove 11 and a second groove 12 adapted to the first fixing member 61 and the second fixing member 62 respectively above and below. The two ends of the rotating shaft 2 extend into the first groove 11 and the second groove 12 respectively, and the two ends of the rotating shaft 2 pass through the through holes of the first fixing member 61 and the second fixing member 62, so that the first fixing member 61 and the second fixing member 62 are respectively embedded in the first groove 11 and the second groove 12, fixing the rotating shaft 2 to the base 1. In this embodiment, the first fixing member 61 is a nut embedded in the first groove 11.

[0051] In order to improve the stability of the rotating shaft 2 and the base 1, in this embodiment, a first step 21 flush with the bottom of the first groove 11 is provided above the rotating shaft 2. After the first fixing member 61 is embedded in the first groove 11, the bottom of the first fixing member 61 presses against the first step 21. The rotating shaft 2 is also provided with a second step 22 that is flush with the bottom of the second groove 12; the second fixing member 62 includes a cover plate 622 disposed in the second groove 12 and a screw 621 that passes through the cover plate 622 and connects to the rotating shaft 2. At least part of the cover plate 622 is embedded in the second groove 12, so that the first protrusion 6221 of the cover plate 622 abuts against the second step 22, and after the second protrusion 6222 of the cover plate 622 abuts against the end of the screw, the screw 621 passes through the cover plate 622 and abuts against the lower end of the second protrusion 6222 and then enters into the rotating shaft 2 to lock the rotating shaft 2 and the base 1.

[0052] In this embodiment, the cleaning mechanism also includes a second driving component 5. The second driving component 5 and the cleaning component 100 are respectively disposed above and below the support 312, and the second driving component 5 is connected to the cleaning component 100 to provide driving force for the cleaning component 100, thereby realizing the rotation of the cleaning component 100.

[0053] More specifically, please refer to Figures 6 and 7. The second drive assembly 5 includes a second drive element 51 and a drive element 52 connected to the second drive element 51.The third gear 52 is connected to the fourth gear 53, which meshes with the third gear 52. The fourth gear 53 is connected to the cleaning component 100 so that the driving force generated by the second driving component 51 can be transmitted to the third gear 52 and then to the fourth gear 53, thereby driving the cleaning component 100 to rotate. It is worth noting that since the entire second driving component 51 can rotate with the swing component 42, in this embodiment, when the cleaning component 100 moves in any position between the inward and outward positions, or between the inward and outward positions, the second driving component 51 will move with the swing component 42 within the accommodating space of the base 1. The purpose of this arrangement is that the second driving component 5 and the cleaning component 100 are arranged vertically on both sides of the swing component 42, and the second driving component 5 does not interfere with the position of the base 1 when it moves, making this part of the structure compact and making reasonable use of space.

[0054] Referring to Figure 11, the cleaning mechanism also includes a first detection component 7 connected to the electronic control unit. The first detection component 7 detects the state of the outward expansion position of the cleaning component 100 by detecting the position of the connecting part 413. That is, the first detection component 7 is adapted to detect whether the cleaning component 100 has reached the outward expansion position when it moves from the inward position to the outward expansion position. During the process of the cleaning component 100 moving from the inward position to the outward expansion position, the first detection component 7 is adapted to emit a first arrival signal. When the electronic control unit receives the first arrival signal, it indicates that the cleaning component 100 has reached the outward expansion position. The electronic control unit controls the first driving component 43 to stop running according to the first arrival signal, that is, the first driving component 43 stops rotating in the first direction.

[0055] It is worth noting that in this embodiment, since the second gear 415 is driven by an external force to rotate the swinging component, the cleaning component 100 connected to the swinging component 42 moves between the outward expansion position and the inward position. Therefore, in this embodiment, the first detection component 7 detects the state of the cleaning component in the outward expansion position or the inward expansion position by detecting the position state of the connecting part 413. In this embodiment, the first detection component 7 is specifically configured as follows: The first detection component 7 includes a first transmitter 71 and a first receiver 72 that cooperates with the first transmitter 71. The first transmitter 71 is disposed on one of the side wall of the connecting portion 413 of the second gear 415 and the inner side wall of the base 1, and the first receiver 72 is disposed on the other side wall of the connecting portion 413 of the second gear 415 and the inner side wall of the base 1. When the first driving member 43 drives the first gear 414 to rotate in the first direction, the gear portion 412 of the second gear 415 drives the connecting portion 413 to rotate in the second direction, thereby driving the cleaning member 100 to move from the inward position to the outward position. At the same time, when the first transmitter 71 or the first receiver 72 disposed on the side wall of the connecting portion 413 rotates to the outward position, the first transmitter 71 will transmit a first arrival signal to the first receiver 72, and the first receiver 72 will transmit the first arrival signal to...The electrical control unit controls the first driving member 43 to stop operating; conversely, if the first receiving member 72 cannot receive the first positioning signal emitted by the first transmitting member 71, it indicates that the cleaning member 100 is not in the outward expansion position, and the first driving member 43 will continue to move in the first direction. It should be noted that in this embodiment, the photoelectric switch positioning detection is preferred, which has higher reliability than other continuous switches.

[0056] Similarly, please refer to FIG12, the cleaning mechanism also includes a second detection component 8 connected to the electrical control unit. The second detection component 8 is adapted to detect the state of the inward position of the cleaning member 100 by detecting the position of the detection connection part 413, that is, the second detection component 8 is adapted to detect whether the cleaning member 100 has reached the inward position during the process of the cleaning member 100 moving from the outward expansion position to the inward position. When the cleaning member 100 moves from the outward expansion position to the inward position, the second detection component 8 is adapted to emit a second positioning signal to the electrical control unit, and the electrical control unit controls the first driving member 43 to stop operating according to the second positioning signal, that is, the first driving member 43 stops rotating in the second direction.

[0057] In this embodiment, the second detection component 8 also detects whether the cleaning component 100 is in an outward or inward position by detecting the position of the connecting part 413. In this embodiment, the second detection component 8 is specifically configured as follows: the second detection component 8 includes a second transmitter 81 and a second receiver 82 that cooperates with the second transmitter 81. The second transmitter 81 is disposed on one of the bottom of the connecting part 413 and the inner bottom wall of the base 1, and the second receiver 82 is disposed on the other of the bottom of the connecting part 413 and the inner bottom wall of the base 1. When the first driving member 43 drives the first gear 414 to rotate in the second direction, the gear portion 412 of the second gear 415 removes the driving force applied to the actuator 421. Under the action of its elastic force and the external force of the obstacle, the actuator 421 changes from the outward expansion position to the inward retraction position. At the same time, the second transmitter 81 or the second receiver 82 provided on the bottom of the connecting portion 413 also rotates to the inward retraction position. The second transmitter 81 will emit a second positioning signal to the second receiver 82, and the second receiver 82 will transmit the second positioning signal to the electronic control unit. The electronic control unit controls the first driving member 43 to stop running. Conversely, if the second receiver 82 cannot receive the second positioning signal emitted by the second transmitter 81, it indicates that the cleaning member 100 is not in the inward retraction position, and the first driving member 43 will continue to rotate in the second direction. Similarly, in this embodiment, photoelectric switch positioning detection is preferred, which has higher reliability than other continuous switches. It is worth noting that in this embodiment, the control logic between the outward expansion position (page 8 / 9 of the specification, CN 121465442 A) and the inward retraction position of the cleaning component is as follows: When the cleaning component moves toward the outward expansion position, the first driving component 43 rotates to drive the transmission component 41 and the swing component 42 to rotate. At this time, the first detection component 7 is adapted to detect the position of the transmission component 41.The first drive component 43 stops rotating when the transmission component 41 reaches a preset position, i.e., when the cleaning component reaches the outward expansion position. Since a torsion spring is installed between the swing component 42 and the transmission component 41, the torsion spring also drives the cleaning component to swing outward. The outward swing angle of the cleaning component is uncertain, depending on whether the cleaning component is affected by external obstacles or walls, and is related to the force on the torsion spring. When the cleaning component moves towards the inward position, theoretically, the time required for the first drive component 43 to drive the cleaning component to swing inward by A° is t1. However, in reality, due to the tolerance in the transmission process of the first and second gears, the actual driving time of the motor during inward control is t1 + t2. During t2, the cleaning component continues to retract, which can offset the tolerance of the first and second gear transmission. During the inward retraction process, the second detection component detects the position of the transmission component 41. Since the transmission component and the swing component 42 are in hard contact, when the second detection component detects that the cleaning component is in the inward state, the first drive component 43 will continue to run for t2 hours. At the end of t2 hours, the first drive component 43 stops rotating. (That is, the retracted position is detected first, and then the motor continues to rotate for a duration of t2). In this embodiment, t2 = 0-5 seconds, preferably 2 seconds. In this application, please refer to Figures 1 and 6. The cleaning mechanism also includes a first shock-absorbing component 9, which is adapted to prevent the cleaning component 3 from colliding with the base 1 when rotating from the outward expansion position to the retracted position. Specifically, the first shock-absorbing component 9 includes a first shock absorber 91 disposed on the second drive component 5, and the base 1 includes a first abutment portion 13. When the cleaning component 100 is in the retracted position, the first shock absorber 91 contacts the first abutment portion 13, and there is a gap between the cleaning component 3 and the base 1 in the horizontal direction. It can also be understood that when the cleaning component 100 is in the retracted position, only the first shock absorber 91 contacts the base 1, and other parts do not contact the base 1, so as to prevent the cleaning mechanism from colliding with the base 1.

[0058] The cleaning mechanism also includes a second shock-absorbing component 10, which is adapted to prevent the cleaning component 3 from colliding with the base 1 when rotating from the inward position to the outward position. Specifically, the second shock-absorbing component 10 includes a second shock absorber 101 disposed on the second drive component 5, and the base 1 includes a second abutment portion 14 disposed on the inner wall. When the cleaning component 100 is in the outward position, the second shock absorber 101 contacts the second abutment portion 14, and there is a gap between the cleaning component 3 and the inner wall of the base 1 in the horizontal direction. It can also be understood that when the cleaning component 100 is in the outward position, only the second shock absorber 101 contacts the inner wall of the base 1, and other parts do not contact the base 1, preventing the cleaning mechanism from colliding with the inner wall of the base 1. It should be noted that in this embodiment, the first shock absorber 91 and the second shock absorber 101 are both made of silicone.
