Description

Technical Field

[0001] This application relates to the field of cleaning robot technology, specifically to a lifting drive component, a cleaning device, and a cleaning equipment. Background Technology

[0002] With the development of technology, cleaning devices have gradually become indispensable tools for daily cleaning. For example, sweeping machines, floor scrubbers, mops, and window cleaners are becoming increasingly popular. Cleaning devices often have multiple cleaning components with different functions, such as dry vacuuming components, wet mopping components, and drying components. When these cleaning components are working, they need to be in close contact with the surface to be cleaned. When these components are not working, they often need to be removed from the surface. For example, when the device needs to cross obstacles such as steps, the cleaning components often need to be lifted off the ground. Similarly, when the device is working on carpets or wooden floors, the wet mopping component often needs to be lifted off the ground. In related technologies, the lifting and lowering of different cleaning components is often controlled by independent drive devices, requiring each cleaning component to have its own independent lifting drive device, resulting in high costs and large space requirements. Therefore, a new lifting drive method is needed, which can use a single drive system to control the lifting and lowering of multiple different cleaning components. Utility Model Content

Figure 1 and Figure 2 The cleaning device 100 may have a direction of travel F, and may clean the surface to be cleaned by using at least one of a plurality of cleaning components such as dry cleaning component 102, first cleaning component 103, second cleaning component 104 and third cleaning component 105 in the direction of travel F.

[0059] The main body 101 may be a shell structure or a frame structure. In some embodiments, the main body 101 may have a walking mechanism such as pulleys, and thus may have a forward direction F. Of course, in other embodiments, the walking mechanism may not be part of the main body 101. In some embodiments, the dry cleaning component 102 may also be part of the main body 101.

[0060] The second cleaning component 104 can be mounted on the main body 101 and positioned behind (to the rear) of the dry cleaning component 102 in the direction of travel F, so as to clean at least part of the area on the surface to be cleaned that has been cleaned by the dry cleaning component 102. In some embodiments, the second cleaning component 104 may also be part of the main body 101.

Furthermore, the dry cleaning component 102 can be slidably positioned in the cleaning position to clean the surface to be cleaned, or slidably positioned in the storage position to be stored on the main body 101, or slidably positioned between the cleaning and storage positions. In a further embodiment, the dry cleaning component 102 can be driven to rise and fall by the lifting drive component 106. The cooperation and connection methods between the lifting drive component 106 and the dry cleaning component 102 can be found in the cooperation and connection methods between the lifting drive component 106 and the first cleaning component 103, the second cleaning component 104, or the third cleaning component 105, which will not be elaborated further.

[0062] The first cleaning component 103 can be mounted on the main body 101 and positioned behind the second cleaning component 104 in the direction of travel F, so as to clean at least a portion of the area on the surface to be cleaned that has been cleaned by the second cleaning component 104. That is, the second cleaning component 104 can be located between the dry cleaning component 102 and the first cleaning component 103. In some embodiments, the first cleaning component 103 can also be part of the main body 101. In some embodiments, the first cleaning component 103 can be slidably connected to the main body 101 through a slide rail, slide groove, connecting rod, or other structure.

[0064] The third cleaning component 105 may be located on one or both sides of the second cleaning component 104 in a first direction intersecting with the direction of travel F, or on one or both sides of the first cleaning component 103 in the first direction, or on one or both sides of the dry cleaning component 102 in the first direction.

[0065] In some embodiments, in the direction of travel F, the third cleaning component 105 is closer to the second cleaning component 104 or the dry cleaning component 102 than the first cleaning component 103.

[0066] Of course, in other embodiments, the third cleaning component 105 may be mounted on the main body 101 and may be located behind the first cleaning component 103 in the direction of travel F, so as to clean at least part of the area on the surface to be cleaned that has been cleaned by the first cleaning component 103. That is, the first cleaning component 103 may be located between the second cleaning component 104 and the third cleaning component 105.

[0067] In some embodiments, the third cleaning component 105 can be slidably connected to the main body 101 via a slide rail, slide groove, connecting rod, or other structure. Of course, other structures known to those skilled in the art can also be used for slidable connection with the main body 101, which will not be elaborated further.

[0069] In some embodiments, the cleaning device 100 may have a first operating mode, in which the first cleaning component 103 is in a cleaning position, and the second cleaning component 104 and the third cleaning component 105 are in a storage position. In some embodiments, in the first operating mode, the direction of travel F may be a straight direction of travel or a turning direction of travel.

[0070] In some embodiments, the cleaning device 100 may have a second operating mode, in which the first cleaning component 103 and the second cleaning component 104 are in the cleaning position, and the third cleaning component 105 is in the storage position.

However, in order to raise and lower the dry cleaning component 102, the first cleaning component 103, the second cleaning component 104 and / or the third cleaning component 105, it is not necessary to use a sliding connection. A rotating connection can also be used to allow the dry cleaning component 102, the first cleaning component 103, the second cleaning component 104 and / or the third cleaning component 105 to swing around an axis to achieve raising and lowering. Other methods that can achieve raising and lowering and are well known to those skilled in the art can also be used, which will not be elaborated here.

The transmission assembly 20 may be connected to the first cleaning assembly 103 and the second cleaning assembly 104. The transmission assembly 20 can control the lifting and lowering of the first cleaning assembly 103 and the second cleaning assembly 104. In some embodiments, the transmission assembly 20 may also be connected to a third cleaning assembly 105. The transmission assembly 20 can also control the lifting and lowering of the third cleaning assembly 105. In some embodiments, the transmission assembly 20 may also be connected to a dry cleaning assembly 102, thereby controlling the lifting and lowering of the dry cleaning assembly 102. For details on the connection and cooperation between the transmission component 20 and the dry cleaning component 102, please refer to the connection and cooperation between the transmission component 20 and the first cleaning component 103, the second cleaning component 104 and / or the third cleaning component 105, which will not be elaborated here.

[0074] Please see Figure 5 , Figure 5 for Figure 3 The illustrated embodiment shows a schematic diagram of the drive motor 10. In some embodiments, the drive motor 10 may be a servo motor. Since the lifting strokes of the first cleaning component 103, the second cleaning component 104, and the third cleaning component 105 are relatively small, using a servo motor for drive can achieve precise control while reducing costs and simplifying the structure and control complexity. In some embodiments, the drive motor 10 may also be a conventionally designed motor, a stepper motor, or other types of motors, which will not be elaborated further. The drive motor 10 may have an output shaft 11 that is connected to the transmission component 20.

The transmission assembly 20 may include a mounting base 21 and a transmission mechanism rotatably connected to the mounting base 21. The transmission mechanism may include a first transmission mechanism 22 rotatably connected to the mounting base 21, a second transmission mechanism 23 rotatably connected to the mounting base 21, and a third transmission mechanism 24 rotatably connected to the mounting base 21.

[0076] Mounting base 21 can be used to support and mount transmission mechanisms such as first transmission mechanism 22, second transmission mechanism 23, third transmission mechanism 24, etc. These transmission mechanisms, such as first transmission mechanism 22, second transmission mechanism 23, and third transmission mechanism 24, can be connected to the drive motor 10. Each transmission mechanism can be connected to a cleaning component. For example, first transmission mechanism 22 can be connected to first cleaning component 103. For example, second transmission mechanism 23 can be connected to second cleaning component 104. For example, third transmission mechanism 24 can be connected to third cleaning component 105. For example, one transmission mechanism can be connected to dry cleaning component 102.

[0077] In some embodiments, when the drive motor 10 rotates in the first rotation direction, it drives the first transmission mechanism 22 and the second transmission mechanism 23 in sequence, causing the first cleaning component 103 to descend first, followed by the second cleaning component 104.

[0078] In some embodiments, when the drive motor 10 rotates in the second rotation direction, it drives the first transmission mechanism 22 and the second transmission mechanism 23 in sequence, causing the second cleaning component 104 to rise first and the first cleaning component 103 to rise later.

[0079] This application improves the standby time and intelligence of the cleaning device 100 by raising unused cleaning components so that cleaning components suitable for the current cleaning task can be lowered.

[0080] In some embodiments, the first cleaning component 103 performs the main cleaning task, while the second cleaning component 104 assists the first cleaning component 103 in cleaning. Then, the drive motor 10 can rotate in the first rotation direction to drive the first transmission mechanism 22, causing the first cleaning component 103 to descend first for cleaning.

[0081] When the second cleaning component 104 is needed to assist the first cleaning component 103, the drive motor 10 can continue to rotate in the first rotation direction, driving the first transmission mechanism 22 and the second transmission mechanism 23 in turn, which in turn drives the second cleaning component 104 to descend and perform cleaning.

[0082] Then, when the second cleaning component 104 is not needed to assist the first cleaning component 103, the drive motor 10 can continue to rotate in the second rotation direction, driving the first transmission mechanism 22 and the second transmission mechanism 23 in turn, thereby raising the second cleaning component 104 and ensuring that the first cleaning component 103 is cleaned.

[0083] Finally, when the first cleaning component 103 is no longer needed, the drive motor 10 rotates in the second rotation direction, driving the first transmission mechanism 22 and causing the first cleaning component 103 to rise.

[0084] This application achieves the sequential lifting and lowering of multiple cleaning components using a single drive motor. Compared to setting a drive motor for each cleaning component, this application has a simpler overall structure and occupies less space. Compared to a single motor driving multiple cleaning components to rise or fall together, this application makes it easier to achieve independent lifting and lowering control of the cleaning components, select the cleaning component that is more suitable for the current cleaning task, and improve the level of intelligence and standby time.

[0085] In some embodiments, when the drive motor 10 rotates in the first rotation direction, it drives the first transmission mechanism 22, the second transmission mechanism 23 and the third transmission mechanism 24 in sequence, causing the first cleaning component 103 to descend first, the second cleaning component 104 to descend next, and the third cleaning component 105 to descend last.

[0086] In some embodiments, when the drive motor 10 rotates in the second rotation direction, it sequentially drives the third transmission mechanism 24, the second transmission mechanism 23, and the first transmission mechanism 22, causing the third cleaning component 105 to rise first, the second cleaning component 104 to rise next, and the first cleaning component 103 to rise last. The first rotation direction is opposite to the second rotation direction.

[0087] In some embodiments, when the drive motor 10 rotates in the first rotation direction, it drives the transmission mechanism, the first transmission mechanism 22, the second transmission mechanism 23 and the third transmission mechanism 24 in sequence, causing the dry cleaning component 102 to descend first, the first cleaning component 103 to descend next, the second cleaning component 104 to descend next, and the third cleaning component 105 to descend next.

[0088] In some embodiments, when the drive motor 10 rotates in the second rotation direction, it drives the third transmission mechanism 24, the second transmission mechanism 23, the first transmission mechanism 22 and the transmission mechanism in sequence, causing the third cleaning component 105 to rise first, the second cleaning component 104 to rise next, the first cleaning component 103 to rise next, and the dry cleaning component 102 to rise next.

[0089] In some embodiments, the first transmission mechanism 22 may be omitted, the second transmission mechanism 23 may be referred to as the first transmission mechanism, and the third transmission mechanism 24 may be referred to as the second transmission mechanism.

[0090] In some embodiments, the second transmission mechanism 23 may be omitted, and the third transmission mechanism 24 may be referred to as the second transmission mechanism.

[0091] In some embodiments, the transmission mechanism connected to the dry cleaning assembly 102 may be referred to as the first transmission mechanism. In a further embodiment, the first transmission mechanism 22 or the third transmission mechanism 24 may be referred to as the second transmission mechanism.

[0092] The mounting base 21 may have a frame structure. A rotating shaft 211 may be provided on the mounting base 21 to cooperate with a transmission mechanism. In some embodiments, the rotating shaft 211 may be rotatably mounted or fixedly mounted.

[0093] In some embodiments, multiple transmission mechanisms can be cascaded. For example, the first transmission mechanism 22 and the second transmission mechanism 23 can be cascaded. For example, the first transmission mechanism 22, the second transmission mechanism 23, and the third transmission mechanism 24 can be cascaded. For example, a single transmission mechanism, the first transmission mechanism 22, the second transmission mechanism 23, and the third transmission mechanism 24 can be cascaded.

[0094] Please see Figure 7 and Figure 8 The first transmission mechanism 22 may include a first transmission wheel 221 rotatably connected to the mounting base 21, for example, a rotating shaft 211, and a first cable 31 connected to the first transmission wheel 221. Alternatively, the first transmission wheel 221 may not be rotatably connected to the mounting base 21 via the rotating shaft 211, but may be rotatably connected to the mounting base 21 in other ways, which will not be elaborated further. In some embodiments, the first transmission wheel 221 may be directly connected to the drive motor 10, for example, an output shaft 11. In some embodiments, the first transmission wheel 221 may be connected to the drive motor 10, for example, an output shaft 11, via the rotating shaft 211. For example, the first transmission wheel 221 may be mounted on the rotating shaft 211, and the rotating shaft 211 may be connected to the drive motor 10, for example, an output shaft 11.

[0095] In some embodiments, the first cable 31 may be part of the traction assembly 30, but not part of the transmission assembly 20. That is, the traction assembly 30 may include the first cable 31. In a further embodiment, the first cable 31 may be connected to the transmission assembly 20 and / or the first cleaning assembly 103 by snap-fit, screw-fit, welding, bonding, or other connection methods well known to those skilled in the art, such that the transmission assembly 20 may pull the first cleaning assembly 103 via the first cable 31 for lifting and lowering. In some embodiments, the first cable 31 may be detachably connected to the transmission assembly 20 and / or the first cleaning assembly 103.

[0096] Please see Figure 4 and Figure 9 , Figure 9 for Figure 3 The illustrated embodiment shows a schematic diagram of the connection between the first cable 31 and the first cleaning component 103. A first limiting block 311 may be provided at one end of the first cable 31 connected to the first cleaning component 103. The first cleaning component 103 may be provided with a first slot 1031 and a first curved groove 1032. The first curved groove 1032 can connect the inside and outside of the first slot 1031. The first cable 31 passes through the first curved groove 1032, and the first limiting block 311 is limited within the first slot 1031 to achieve a detachable connection between the first cable 31 and the first cleaning component 103. Specifically, the first curved groove 1032 is provided on the side wall and / or bottom wall of the first slot 1031.

[0097] During installation, the first limiting block 311 extends into the first slot 1031 from its opening, while the other parts of the first pull cable 31, excluding the first limiting block 311, extend into the first curved groove 1032 from its opening. The pull cable 31 then exerts traction force towards the outside of the first slot 1031. Because the first limiting block 311 cannot enter the first curved groove 1032, it remains confined within the slot and cannot slide out, thus connecting the first pull cable 31 to the first cleaning component 103. Furthermore, the tortuous design of the first curved groove 1032 also prevents the other parts of the first pull cable 31, excluding the first limiting block 311, from sliding towards the opening of the groove, ensuring the reliability of the connection between the first pull cable 31 and the first cleaning component 103.

[0098] Please see Figure 4 The first transmission mechanism 22 can be connected to the first cleaning component 103 via a traction component 30, such as a first cable 31. In some embodiments, the connection between the first transmission mechanism 22 and the first cleaning component 103 is not limited to the traction component 30, but can also be achieved through a gear, slide bar, or other structures known to those skilled in the art to realize the raising and lowering of the first cleaning component 103.

The first limiting block 311 on the end of the first cable 31 that is connected to the first drive wheel 221 can extend into the first locking groove 222 and be limited within the first locking groove 222 to achieve connection.

[0102] In some embodiments, the traction component 30, such as the first cable 31, may be wound around the first transmission mechanism 22, such as the first transmission wheel 221. In some embodiments, the side circumferential surface of the first transmission wheel 221 is provided with a first winding groove 223 so that the traction component 30, such as the first cable 31, is wound around the first winding groove 223. In some embodiments, the first winding groove 223 communicates with the first locking groove 222.

Of course, the second transmission wheel 231 may also be rotatably connected to the mounting base 21 in other ways than via the rotating shaft 211, which will not be elaborated further. In some embodiments, the second transmission wheel 231 and the first transmission wheel 221 may also be non-coaxial. In some embodiments, the second transmission mechanism 23 may be drive-connected to the first transmission wheel 221 to achieve a cascaded transmission connection.

[0104] In some embodiments, the second cable 32 may be part of the traction assembly 30, but not part of the transmission assembly 20. That is, the traction assembly 30 may include the second cable 32. The second cable 32 may be connected to the transmission assembly 20 and / or the second cleaning assembly 104 by snap-fitting, screwing, welding, bonding, or other connection methods well known to those skilled in the art, so that the transmission assembly 20 may pull the second cleaning assembly 104 via the second cable 32 for lifting and lowering.

The second cleaning component 104 may be provided with a second slot 1041 and a second curved groove 1042. The second curved groove 1042 connects the inside and outside of the second slot 1041. The second cable 32 passes through the second curved groove 1042, and the second limiting block 321 is positioned within the second slot 1041 to achieve a detachable connection between the second cable 32 and the second cleaning component 104. Specifically, the second curved groove 1042 is provided on the side wall and / or bottom wall of the second slot 1041.

[0107] During installation, the second limiting block 321 extends into the second slot 1041 from its opening, while the other parts of the second cable 32, excluding the second limiting block 321, extend into the second curved groove 1042 from its opening. The second cable 32 then exerts traction force towards the outside of the second slot 1041. Because the second limiting block 321 cannot enter the second curved groove 1042, it remains confined within the slot and cannot slide out, thus connecting the second cable 32 to the second cleaning component 104. Furthermore, the tortuous design of the second curved groove 1042 also prevents the other parts of the second cable 32, excluding the second limiting block 321, from sliding towards the opening of the groove, ensuring the reliable connection between the second cable 32 and the second cleaning component 104.

[0112] In some embodiments, the traction component 30, such as the second cable 32, may be wound around the second transmission mechanism 23, such as the second transmission wheel 231. In some embodiments, the side circumferential surface of the second transmission wheel 231 is provided with a second winding groove 233 so that the traction component 30, such as the second cable 32, is wound around the second winding groove 233. In some embodiments, the second winding groove 233 communicates with the second locking groove 232.

[0117] During installation, the third limiting block 331 extends into the third slot 1051 from its opening, while the other parts of the third cable 33, excluding the third limiting block 331, extend into the third curved groove 1052 from its opening. The third cable 33 then exerts traction force towards the outside of the third slot 1051. Because the third limiting block 331 cannot enter the third curved groove 1052, it remains confined within the slot and cannot slide out, thus connecting the third cable 33 to the third cleaning component 105. Furthermore, the tortuous design of the third curved groove 1052 also prevents the other parts of the third cable 33, excluding the third limiting block 331, from sliding towards the opening of the groove, ensuring the reliable connection between the third cable 33 and the third cleaning component 105.

[0118] Please see Figure 4 The third transmission mechanism 24 can be connected to the third cleaning component 105 via a traction component 30, such as a third cable 33. In some embodiments, the third cable 33 may be part of the third transmission mechanism 24.

[0123] In some embodiments, the mounting base 21 may be omitted, and the rotating shaft 211 may be replaced by a drive motor 10, such as the output shaft 11, to achieve a cascaded transmission connection of multiple transmission mechanisms.

[0124] In some embodiments, the drive motor 10 may also be fixed on the mounting base 21.

[0125] In some embodiments, the first drive wheel 221 is provided with a first clutch portion 224. The second drive wheel 231 is provided with a second clutch portion 234. The first drive wheel 221 and the second drive wheel 231 can be connected in a cascade transmission manner through the cooperation of the first clutch portion 224 and the second clutch portion 234.

[0126] The first transmission wheel 221 and the second transmission wheel 231 rotate relative to each other, and can rotate to the position where the first clutch part 224 and the second clutch part 234 are connected and engaged, or can rotate to the position where the first clutch part 224 and the second clutch part 234 are separated and disengaged.

[0127] For example, when the first clutch part 224 and the second clutch part 234 are disengaged, the first transmission wheel 221 can rotate in the first rotation direction until it reaches the position where the first clutch part 224 and the second clutch part 234 are engaged, so as to drive the second transmission wheel 231. If the first transmission wheel 221 continues to rotate in the first rotation direction, it can drive the second transmission wheel 231 to rotate. If the first transmission wheel 221 rotates in the second rotation direction, it can cause the first clutch part 224 and the second clutch part 234 to disengage.

[0128] For example, when the first clutch part 224 and the second clutch part 234 are disengaged, the first transmission wheel 221 can rotate in the second rotation direction until it reaches the position where the first clutch part 224 and the second clutch part 234 are engaged, so as to drive the second transmission wheel 231. If the first transmission wheel 221 continues to rotate in the second rotation direction, it can drive the second transmission wheel 231 to rotate. If the first transmission wheel 221 rotates in the first rotation direction, it can cause the first clutch part 224 and the second clutch part 234 to disengage.

[0129] In some embodiments, the engagement of the first clutch portion 224 and the second clutch portion 234 can be a engagement of a protrusion and a structure with a groove, a engagement of a slider and a stop, a engagement of a slide rail and a slider, or even other structures that enable the engagement of the first clutch portion 224 and the second clutch portion 234. In some embodiments, the second clutch portion 234, for example, has a protrusion that extends into a groove in the first clutch portion 224, for example, a structure with a groove, so that the protrusion slides within the groove. In some embodiments, the first clutch portion 224, for example, has a slider that slides between two stops in the second clutch portion 234. In some embodiments, the second clutch portion 234, for example, has a slider that is slidably connected to the first clutch portion 224, for example, a slide rail, so that the slider slides on the slide rail.

[0130] In some embodiments, the first clutch portion 224 and the second clutch portion 234 are disposed opposite to each other. In some embodiments, the first drive wheel 221 and the second drive wheel 231 are coaxially disposed such that the first clutch portion 224 is disposed on the side of the first drive wheel 221 near the second drive wheel 231, and the second clutch portion 234 is disposed on the side of the second drive wheel 231 near the first drive wheel 221.

[0131] In some embodiments, one of the first clutch portion 224 and the second clutch portion 234 is provided with a groove, such as a transmission groove, and the other includes a slider, such as a transmission pin. The transmission groove is distributed within a preset angle, such as a first preset angle, in the circumference of the first transmission wheel 221 or the second transmission wheel 231, and the transmission pin can pass through the transmission groove. In some embodiments, the preset angle, such as the first preset angle, can be 10-360°. In some embodiments, the preset angle, such as the first preset angle, can be 45-135°. In some embodiments, the preset angle, such as the first preset angle, can be 90°. In some embodiments, when the transmission pin abuts against the end of the transmission groove, the first clutch portion 224 and the second clutch portion 234 are connected; when the transmission pin does not abut against the end of the transmission groove, the first clutch portion 224 and the second clutch portion 234 are separated.

[0132] In some embodiments, the second drive wheel 231 is provided with a third clutch portion 235. The third drive wheel 241 is provided with a fourth clutch portion 244. The second drive wheel 231 and the third drive wheel 241 can achieve a cascaded transmission connection through the cooperation of the third clutch portion 235 and the fourth clutch portion 244.

[0133] The second drive wheel 231 and the third drive wheel 241 rotate relative to each other, and can rotate to the position where the third clutch part 235 and the fourth clutch part 244 are connected and engaged, or can rotate to the position where the third clutch part 235 and the fourth clutch part 244 are disengaged.

[0134] For example, when the third clutch part 235 and the fourth clutch part 244 are disengaged, the second drive wheel 231 can rotate in the first rotation direction until it reaches the position where the third clutch part 235 and the fourth clutch part 244 are engaged, so as to drive the third drive wheel 241. If the second drive wheel 231 continues to rotate in the first rotation direction, it can drive the third drive wheel 241 to rotate. If the second drive wheel 231 rotates in the second rotation direction, it can cause the third clutch part 235 and the fourth clutch part 244 to disengage.

[0135] For example, when the third clutch part 235 and the fourth clutch part 244 are disengaged, the second drive wheel 231 can rotate in the second rotation direction until it reaches the position where the third clutch part 235 and the fourth clutch part 244 are engaged, so as to drive the third drive wheel 241. If the second drive wheel 231 continues to rotate in the second rotation direction, it can drive the third drive wheel 241 to rotate. If the second drive wheel 231 rotates in the first rotation direction, it can cause the third clutch part 235 and the fourth clutch part 244 to disengage.

[0136] In some embodiments, the engagement of the third clutch portion 235 and the fourth clutch portion 244 can be a engagement of a protrusion and a structure with a groove, a engagement of a slider and a stop, a engagement of a slide rail and a slider, or even other structures that enable the engagement of the third clutch portion 235 and the fourth clutch portion 244. In some embodiments, the fourth clutch portion 244, for example, has a protrusion that extends into a groove in the third clutch portion 235, for example, a structure with a groove, so that the protrusion slides within the groove. In some embodiments, the third clutch portion 235, for example, has a slider that slides between two stops in the fourth clutch portion 244. In some embodiments, the fourth clutch portion 244, for example, has a slider that is slidably connected to the third clutch portion 235, for example, a slide rail, so that the slider slides on the slide rail.

[0137] In some embodiments, the third clutch portion 235 and the fourth clutch portion 244 are disposed opposite to each other. In some embodiments, the second drive wheel 231 and the third drive wheel 241 are coaxially disposed such that the third clutch portion 235 is disposed on the side of the second drive wheel 231 near the third drive wheel 241, and the fourth clutch portion 244 is disposed on the side of the third drive wheel 241 near the second drive wheel 231.

[0138] In some embodiments, one of the third clutch portion 235 and the fourth clutch portion 244 is provided with a groove, such as a transmission groove, and the other includes a slider, such as a transmission pin. The transmission groove is distributed within a preset angle, such as a second preset angle, in the circumference of the second transmission wheel 231 or the third transmission wheel 241, and the transmission pin can pass through the transmission groove.
