Description

Technical Field

[0001] This application relates to the field of automatic cleaning technology, and in particular to a ramp, base station, and cleaning system. Background Technology

[0002] With the development of cleaning technology, various intelligent robots have emerged as cleaning devices, such as robotic vacuum cleaners, robotic mops, and vacuum cleaners. These cleaning devices can automatically move and perform cleaning or tidying operations in a specific area without user intervention. After completing their cleaning tasks, the devices connect to a base station and utilize the base station for dust removal and cleaning to maintain optimal cleaning performance.

[0003] Inside the cleaning device, to prevent dust and debris from entering the suction fan during vacuuming, a filter is typically installed between the dust collection chamber and the suction fan, keeping dust and debris trapped in the dust collection chamber. In existing base stations, when the cleaning device collects dust, the negative pressure flow generated by the base station collects the debris from the dust collection chamber into components such as the base station's dust collection bag. However, a large amount of debris often remains in the filter, causing it to become clogged, thus affecting the cleaning effect and reducing the user experience. Utility Model Content

[0004] This application discloses a ramp, a base station, and a cleaning system for improving the cleaning effect of the filter and reducing filter clogging.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] In a first aspect, this application provides a ramp slab, which includes a support and an inclined plate fixedly connected to the support;

[0007] The ramp plate has a first notch, and a sealing plate is provided at the first notch; the sealing plate covers the first notch in the first position state; the sealing plate is used to cover the main brush port of the cleaning device in the second position state.

[0008] The ramp plate of this application is located at the bottom of the base station and can serve as the base plate of the base station. Since the sealing plate covers the first notch in the first position and covers the main brush opening of the cleaning device in the second position, when the base station assembled using this ramp plate is connected to the base station, the sealing plate can be used to block the main brush opening of the cleaning device. Then, when the base station collects dust from the cleaning device, the dust-collecting airflow can enter the dust collection chamber from the dust removal fan side of the cleaning device. Relative to the dust removal airflow of the cleaning device, this dust collection process is equivalent to applying a reverse airflow to the filter screen. That is, after the main brush opening of the cleaning device is blocked by the sealing plate, the dust-collecting airflow will pass through the filter screen and enter the dust collection chamber from the dust removal fan side, thereby carrying away the debris adhering to the filter screen, thus improving the cleaning effect of the filter screen and reducing filter screen clogging.

[0009] In one implementation, the ramp slab further includes at least one drive mechanism connected to the sealing plate, for driving the sealing plate to switch between a first position state and a second position state. By using the drive mechanism to drive the sealing plate to switch between the first and second position states, automated control is achieved.

[0010] In one implementation, the driving mechanism includes a driving unit, the output end of which is rotatably connected to the sealing plate. Since the ramp plate is an inclined plate, the sealing plate can be in an inclined state when covering the first notch, and in a horizontal state when covering the main brush opening of the cleaning device. Therefore, by using a rotating configuration, the sealing plate can achieve a higher degree of fit with the first notch and the main brush opening.

[0011] In one implementation, the driving mechanism includes a driving unit and a driving rod connected to the output end of the driving unit; the driving unit is capable of driving the driving rod to rotate relative to the bracket. Automatic control can be achieved by using the driving unit to drive the sealing plate to rotate. As an example, the driving unit can be one of a cylinder, a hydraulic cylinder, or a motor. The output shaft of the cylinder, hydraulic cylinder, or motor can be directly connected to the sealing plate, thereby driving the sealing plate to rotate.

[0012] In one implementation, the first end of the drive rod is fixedly connected to the sealing plate, and the second end of the drive rod is rotatably connected to the bracket. The drive unit can drive the drive rod to rotate around the second end. By using the rotatable connection between the drive rod and the bracket to form a first rotation center, the convenience of the connection position of the drive mechanism can be increased.

[0013] In one implementation, the angle between the extension direction of the drive rod and the surface of the sealing plate is less than 90°. The angle between the drive rod and the sealing plate is the same as or similar to the slope of the ramp, for example, the angle difference can be controlled within 10°, 5°, or 3°. Since the sealing plate needs to cooperate with the ramp when it is on the ramp to avoid affecting the movement of the cleaning device, the inclined connection between the drive rod and the sealing plate facilitates the setting of the drive mechanism and simplifies its structure.

[0014] In one implementation, along the extension direction of the drive rod, the connection point between the drive part and the drive rod is located between the first end and the second end of the drive rod; and / or, along the extension direction of the drive rod, the distance between the connection point of the drive part and the drive rod and the first end is greater than the distance between the connection point and the second end. The drive part is connected to the middle portion of the drive rod for driving the drive rod to rotate, which can reduce the driving torque.

[0015] In one implementation, the drive rod has a second notch for connecting to the output end of the drive unit. In another implementation, the drive rod includes a first rod body and a second rod body fixedly connected, the first rod body being connected to the sealing plate, and the second rod body being rotatably connected to the bracket. The second notch is located on the second rod body.

[0016] The connection point between the drive unit and the drive rod is located on the second rod body, which is close to the rotation fulcrum of the drive rod. Therefore, according to the lever principle, when the drive unit undergoes a small displacement, the first end of the drive rod can generate a large displacement, thereby allowing the sealing plate to obtain a large rotational stroke. This arrangement reduces the size of the drive unit, making it easier to integrate into the ramp plate.

[0017] In one implementation, the second notch is a groove or a through hole, the opening direction of which is away from the cleaning device.

[0018] Since the drive unit generates an upward driving force on the drive rod, that is, a driving force towards the cleaning device, when the second notch is a groove, the opening of the groove is set downward, that is, set away from the direction of the cleaning device, so as to ensure the stability of the connection between the drive unit and the drive rod and prevent the drive unit from coming out of the groove.

[0019] In one implementation, the first rod and the second rod are offset along the extension direction of the drive rod, and a first reinforcing plate is provided between the first rod and the second rod.

[0020] By setting a first reinforcing plate, the connection strength between the first rod and the second rod can be improved, preventing the second rod from breaking when subjected to force.

[0021] In one implementation, the drive unit includes a linkage assembly, one end of which is an output end rotatably connected to the drive rod, and the other end is suspended in the air.

[0022] One suspended end of the linkage assembly can serve as a pressure-sensitive end. When the pressure-sensitive end is pressed and moves along a first direction, the output end of the linkage assembly can move in the opposite direction of the first direction. By using the linkage assembly as the driving unit, the structure of the driving unit can be reduced, and the driving rod can be driven only through structural components, thus reducing the use of electrical driving components.

[0023] In one implementation, one end of the linkage assembly is located in the second notch of the drive rod, and the other end is provided with a pressing element. In another implementation, the pressing element includes a roller, which is rotatably connected to the other end of the connecting assembly.

[0024] In one implementation, the linkage assembly includes a first link and a second link; the first link and the second link are configured in an L-shape. A first end of the first link is rotatably connected to the drive rod, and a second end of the first link is rotatably connected to the first end of the second link; the second end of the second link is the pressing end. The pressing element can be located at the pressing end. The linkage assembly consisting of the first link and the second link can realize the function of the drive unit, resulting in a simpler drive structure.

[0025] When the pressure-sensitive element is in a free state, the sealing plate covers the first notch; when the pressure-sensitive element is under pressure, the driving mechanism drives the sealing plate to cover the main brush opening of the cleaning device. The driving unit is activated by pressure, thereby switching the sealing plate between two position states.

[0026] In one implementation, the first link includes a third link and a fourth link fixedly connected, the third link being inserted into the second notch of the drive rod, and the fourth link being rotatably connected to the second link. An L-shaped structure is configured between the first link and the second link to simplify the structural arrangement of the drive assembly.

[0027] In one implementation, a second reinforcing plate is provided between the third rod and the fourth rod. By providing the second reinforcing plate, the connection strength between the third rod and the fourth rod can be improved, preventing the third rod and the fourth rod from breaking under stress.

[0028] In one implementation, the roller is rotatably connected to the second connecting rod. By setting a roller as a pressure element at the second end of the second connecting rod, friction between the drive wheel of the cleaning device and the pressure element can be reduced, thereby improving the service life of the drive mechanism.

[0029] In one implementation, a groove is provided at the second end of the second connecting rod, and the roller is disposed in the groove. By providing a groove at the second end of the second connecting rod, i.e., the contact end, the stability of the roller connection can be increased.

[0030] In one implementation, a third notch is provided at the top of the ramp, and the pressure-sensitive element is located at the third notch, protruding from the third notch. In another implementation, the third notch is positioned corresponding to the location of the drive wheel when the cleaning device is parked on the ramp. The third notch's location corresponding to the drive wheel allows pressure to be applied to the pressure-sensitive element using the drive wheel.

[0031] In one implementation, anti-slip parts are provided on both sides of the slope surface of the ramp, and the sealing plate is disposed between the anti-slip parts.

[0032] In one implementation, the ramp slab has two sets of drive mechanisms, each set corresponding to one of the anti-slip parts. By using two sets of drive mechanisms, the lifting and lowering of the sealing plate can be made smoother and more reliable.

[0033] In one implementation, the sealing plate has a sealing strip on its covering surface, which is the side of the sealing plate facing the cleaning device. By providing the sealing strip, the sealing effect of the sealing plate on the main brush opening can be further improved.

[0034] In one implementation, a reset member is provided between the sealing plate and the bracket. When the sealing plate is in the first state, the reset member is in a storage state to provide the sealing plate with a restoring force to return to the second state.

[0035] Secondly, this application provides a base station, which includes a base station body and a ramp plate disposed within the base station body.

[0036] The ramp can be installed at the bottom of the base station, serving as its base plate. The ramp can be fixedly connected to the base station body or detachably connected.

[0037] Thirdly, this application provides a cleaning system, which includes a cleaning device and a base station of this application; the cleaning device is placed inside the base station.

[0038] In one implementation, the bottom of the cleaning device is provided with a drive wheel and a main brush port; when the drive wheel of the cleaning device is in a preset position of the ramp plate, the sealing plate seals the main brush port of the cleaning device.

[0039] In one implementation, when the cleaning device is placed on the base station, the drive wheel is positioned at the third notch of the ramp plate, and the drive wheel applies pressure to the contact element of the ramp plate; after the contact element is pressed, the drive mechanism drives the sealing plate to cover the main brush opening;

[0040] After the drive wheel leaves the third notch, the pressing element pops up, and the sealing plate returns to its original position to cover the first notch.

[0041] The second and third aspects of this application can achieve the same effect as the first aspect of this application, and will not be repeated here. Attached Figure Description

[0068] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] Figure 1 This is a schematic diagram of a cleaning system. Figure 1As shown, the automated cleaning system 1000 may include a cleaning device 200 and a base station 100. The cleaning device 200 is mainly used to clean debris from surfaces such as floors and carpets. After cleaning, the cleaning device 200 moves to the base station 100 and docks for subsequent maintenance. The base station 100 collects the debris collected by the cleaning device 200 during the cleaning process and charges the cleaning device 200. The cleaning device 200 is a self-moving intelligent cleaning device, such as a robotic vacuum cleaner or a robotic mop. For ease of description, this application uses a robotic vacuum cleaner as an example to describe the technical solution.

[0070] In embodiments of this application, the sweeping robot may include: a robot body, a return-to-base signal receiving device, a control module, a drive component, a dust removal component, a power component, and a human-machine interaction component. These components coordinate with each other, enabling the sweeping robot to move autonomously to achieve its cleaning function. The functional elements constituting the aforementioned components are integrated into the robot body.

[0071] Figure 2 This is a schematic diagram of the internal structure of a robotic vacuum cleaner according to one embodiment. Figure 3 This is a schematic diagram of the bottom structure of a robotic vacuum cleaner according to one embodiment. Figure 2 and Figure 3 As shown, inside the robotic vacuum cleaner, the dust removal components may include a dust removal fan 202, a filter 203, a dustbin 204, and a main brush 205. The main brush 205 is located at the main brush inlet 206 on the robot's chassis. The dustbin 204 forms the robot's dust collection chamber, and the filter 203 can be positioned between the dust removal fan 202 and the dustbin 204. When collecting dust and debris, a negative pressure is created in the path between the main brush inlet 206 and the dust removal fan 202. Under this negative pressure, dust and debris on the ground can enter the dust collection chamber through the main brush inlet 206. The airflow created by the dust removal fan 202 inside the robotic vacuum cleaner... Figure 2 As shown by dashed line A in the diagram. Gas flowing from the dust collection chamber passes through the filter and dust removal fan, and can then be discharged through the vent 207 of the cleaning equipment. The vent 207 serves as the exhaust port for the dust removal fan 202. Due to the interception by the filter 203, most debris is collected in the dust collection chamber, while a small amount of dust and debris may adhere to the filter 203.

[0072] Continue to refer to Figure 2 When the robotic vacuum cleaner docks with the base station and uses the base station to collect dust, the airflow generated by the base station's dust collection fan inside the robotic vacuum cleaner also enters through the brush inlet 206, passes through the dust collection chamber, and then enters the dust collection bag and other dust collection components of the base station through the adjacent dust exhaust pipe. The airflow path created by the negative pressure generated by the base station's dust collection fan inside the robotic vacuum cleaner is as follows: Figure 2As shown by the dashed line B in the diagram.

[0073] During the dust collection process of the robot vacuum cleaner, the dust and debris in the filter 203 cannot be effectively removed. Over time, the filter will become clogged, which will affect the cleaning effect of the robot vacuum cleaner. Therefore, users need to clean or replace the filter 203 frequently.

[0074] Therefore, this application provides a ramp, a base station, a cleaning system, and a dust collection method, so that when the base station collects dust from the cleaning device 200, it changes the airflow path within the cleaning device 200, thereby achieving cleaning of the filter 203.

[0075] Figure 4 This is a schematic diagram of a ramp slab structure. (Example) Figure 4 As shown, the ramp slab 10 includes a support 11, a ramp slab 12, and a sealing plate 20. Combined with... Figure 1 In base station 100, ramp 10 can be installed at the bottom of base station 100 as a base for supporting cleaning device 200. Support 11 can be divided into a cleaning section 111 and a ramp support section 112. The cleaning section 111 can be used to form a cleaning tank. The ramp support section 112 is used to support ramp 12.

[0076] The connection between the cleaning section 111 and the ramp support section 112 can be either detachable or non-detachable, and no specific limitation is made here. The cleaning tank formed by the cleaning section 111 can be used to clean the wiping part of the cleaning device 200.

[0077] The ramp 12 is fixedly connected to the bracket 11. The slope surface of the ramp 12 forms the slope surface of the ramp slab. When the cleaning device 200 docks with the base station 100, the cleaning device 200 travels from the ramp 12 to the cleaning tank and then stops. Afterwards, it can dock with the base station and use the base station to clean the cleaning device 200.

[0078] Reference Figure 4 The ramp 12 has anti-slip sections 121 on both sides of its slope surface. When the cleaning device 200 moves along the ramp 12, its drive wheel 201 can travel along the anti-slip sections 121, which prevent the cleaning device 200 from slipping. Figure 4 In the structure shown, there are two anti-slip parts 121, which are respectively located on both sides of the ramp 12.

[0079] Among them, reference Figure 4 The ramp slab 12 has a first notch 122, and the sealing plate 20 is disposed at the first notch 122. In the ramp slab of this application embodiment, the sealing plate 20 can exist in two position states, namely a first position state and a second position state. Figure 4The first position state of the sealing plate 20 is shown, in which the sealing plate 20 covers the first notch 122. Figure 5 This is a schematic diagram showing the sealing plate in its second position. (Refer to...) Figure 3 and Figure 5 In the second position, the sealing plate 20 covers the main brush port 206 of the cleaning device 200.

[0080] Among them, refer to Figure 3 and Figure 5 The sealing plate is in Figure 5 In the indicated state, the sealing plate 20, in its second position, will cover the main brush opening 206 of the cleaning device 200, completely sealing the main brush opening 206. Therefore, the outline of the sealing plate 20 should match the shape of the main brush opening 206, for example, it can be rectangular. For ease of description, the surface of the sealing plate 20 facing the cleaning device 200 and used to cover the main brush opening 206 is called the top surface, which is the covering surface of the sealing plate. The surface of the sealing plate 20 facing away from the cleaning device 200 is called the bottom surface. The covering surface of the sealing plate 20 can be curved, and its central area can have a recessed area to form a relief groove for the main brush, preventing damage to the main brush 205 when it is covered by the main brush opening 206.

[0081] In one embodiment, a sealing strip may be provided on the covering surface of the sealing plate 20. When the sealing plate covers the main brush opening 206 of the cleaning device 200, the sealing strip is arranged around the main brush opening 206. By providing a sealing strip, the sealing effect of the sealing plate on the main brush opening can be further improved.

[0082] Reference Figures 1 to 5 Because the sealing plate 20 covers the first notch 122 in the first position and covers the main brush port 206 of the cleaning device 200 in the second position, the base station assembled using this ramp can use the sealing plate 20 to block the main brush port 206 of the cleaning device 200 after the cleaning device 200 is connected to the base station 100. Then, when the base station 100 collects dust from the cleaning device 200, the dust collection airflow can flow to the dust collection component of the base station after passing through the filter screen 203 of the cleaning device. For example, the dust collection airflow can enter the dust collection chamber from the dust removal fan 202 side of the cleaning device 200 through the filter screen 203, such as... Figure 2 As shown by the dashed line C in the diagram. The dust removal airflow relative to the cleaning device 200 (e.g., ... Figure 2As shown by the dashed line A, this dust collection process is equivalent to applying a reverse airflow to the filter 203. That is, after the main brush opening 206 of the cleaning device 200 is sealed by the sealing plate 20, the dust-collecting airflow passes through the filter 203 and is blown into the dust box from the side of the dust collector fan 202, thereby carrying away the debris adhering to the filter 203. This improves the cleaning effect of the filter 203 and reduces clogging. In one embodiment, the airflow blown into the dust collection chamber through the filter can enter through the vent 207 of the cleaning device. Alternatively, the gas can also enter through other through-holes connected to the dust collector fan 202.

[0083] Reference Figure 4 and Figure 5 The slope plate 12 has anti-slip parts 121 on both sides of the slope surface. In one embodiment, the sealing plate 20 can be disposed between the two anti-slip parts 121.

[0084] In this embodiment, the ramp 10 further includes at least one set of driving mechanisms. In one embodiment, the ramp 10 has two sets of driving mechanisms, each set corresponding to one of the anti-slip parts. By providing two sets of driving mechanisms, the lifting and lowering of the sealing plate can be made smoother and more reliable.

[0085] Figure 6 This is a schematic diagram of the connection structure between the drive mechanism and the sealing plate in one embodiment. Figure 6 As shown, the driving mechanism 30 is connected to the sealing plate 20 and is used to drive the sealing plate 20 to switch between the first position state and the second position state. Wherein, Figure 6 (a) is a structural schematic diagram of the sealing plate 20 in the first position state. Figure 6 (b) is a schematic diagram of the sealing plate 20 in the second position state. The sealing plate 20 is switched between the first and second position states by the drive mechanism 30, thereby realizing automatic control.

[0086] Among them, reference Figure 6 The driving mechanism 30 may be provided with a first rotation center G1, and the sealing plate 20 can rotate around the first rotation center G1 to switch between the first position state and the second position state. (See also...) Figures 3 to 6 Since the ramp plate 10 is an inclined plate, the sealing plate 20 can be in an inclined state when it covers the first notch 122, and in a horizontal or nearly horizontal state when it covers the main brush port 206 of the cleaning device 200. The specific design can be made according to the structure of the main brush port. Therefore, by using a rotating setting, the sealing plate 20 can achieve a higher degree of coverage with the first notch and the main brush port.

[0087] Continue to refer to Figure 6The driving mechanism 30 may include a driving unit 301, and the sealing plate 20 is rotatably connected to the output end of the driving unit 301 to form the first rotation center G1. Automatic control can be achieved by driving the sealing plate 20 to rotate using the driving unit 301. As an example, the driving unit 301 may be a cylinder, a hydraulic cylinder, or a motor. The output shaft of the cylinder, hydraulic cylinder, or motor may be directly connected to the sealing plate 20, thereby driving the sealing plate to rotate.

[0088] When the drive unit 301 is a power source driver such as a cylinder, hydraulic cylinder, or motor, the drive rod of the aforementioned driver can be directly connected to the sealing plate. Taking a hydraulic cylinder as an example, the hydraulic rod can be connected to the sealing plate. The aforementioned driver can be fixedly connected to the bracket below the ramp plate, thereby driving the sealing plate to move.

[0089] Figure 7 This is a schematic diagram of the drive mechanism according to another embodiment. Figure 7 As shown, the driving mechanism 30 includes a driving part 301 and a driving rod 31 connected to the output end of the driving part 301. The driving part 301 can drive the driving rod 31 to rotate relative to the bracket. The driving rod 31 can be rotatably connected to the bracket, and the rotatable connection point between the driving rod 31 and the bracket can be a first rotation center G1. The driving part 301 is connected to the driving rod 31, and the driving rod 31 is fixedly connected to the sealing plate 20. The driving part 301 drives the driving rod 31 to rotate around the first rotation center G1. Using the driving rod 31 to form the first rotation center G1 increases the convenience of the connection position of the driving mechanism 301.

[0090] like Figure 7 As shown, in one embodiment, the first end of the drive rod 31 is fixedly connected to the sealing plate 20, and the second end of the drive rod 31 is rotatably connected to a bracket (not shown) to form the first rotation center G1. The rotation of the drive rod 31 drives the sealing plate 20 to rotate.

[0091] In one embodiment, such as Figure 7 As shown, along the extending direction of the drive rod 31, the connection point between the drive part 301 and the drive rod 31 is located between the first end and the second end of the drive rod 31, that is, the connection point between the drive part 301 and the drive rod 31 is located in the middle region of the drive rod 31. The drive part 301 is connected to the middle part of the drive rod 31 to drive the drive rod 31 to rotate, which can reduce the driving torque.

[0092] The first end of the drive rod 31 is connected to the sealing plate 20, and when the drive rod 31 moves, it can drive the sealing plate 20 to move. The second end of the drive rod 31 is rotatably connected to the bracket (not shown in the figure). The point of this rotatable connection, namely the first rotation center G1, can serve as the rotation fulcrum of the drive rod 31, thereby causing the drive rod 31 to drive the sealing plate 20 to rotate around the rotation fulcrum. In one embodiment, along the extension direction of the drive rod 31, the distance between the connection point of the drive part 301 and the drive rod 31 and the first end is greater than the distance between the connection point and the second end.

[0093] Figure 8 This is a schematic diagram of a drive rod structure. Figure 8 In one embodiment, the drive rod 31 is provided with a second notch 314, which is used to connect to the output end of the drive unit 301.

[0094] Reference Figure 8 For example, along the extension direction of the drive rod 31, i.e., along the x-direction shown in the figure, the drive rod 31 includes a first rod body 311 and a second rod body 312 fixedly connected. The first rod body 311 and the second rod body 312 may be an integrally connected structure. The first rod body 311 is connected to the sealing plate 20, and the second rod body 312 is rotatably connected to the bracket 11 to form a first rotation center G1. A second notch 314 is provided in the second rod body 312.

[0095] The connection point between the drive unit and the drive rod 31 is located on the second rod body 312, which is close to the first rotation center G1. Therefore, according to the lever principle, when the drive unit undergoes a small displacement, the first end of the drive rod 31 can generate a large displacement, thereby allowing the sealing plate 20 to obtain a large rotation stroke. This arrangement can reduce the size of the drive unit, thus facilitating its integration into the ramp plate.

[0096] Among them, reference Figure 8 The second notch 314 can be a groove or a through hole. The opening direction of the groove is away from the direction of the cleaning device, that is, the opening of the groove can be set downwards. In order to enable the first connecting rod 32 to generate an upward driving force on the driving rod 31, that is, a driving force towards the cleaning device, when the second notch 314 is a groove, the opening of the groove is set downwards, that is, away from the direction of the cleaning device, so as to ensure the stability of the connection between the first connecting rod 32 and the driving rod 31 and prevent the first connecting rod 32 from coming out of the groove. When the second notch 314 is a groove, the second notch 314 can be a semi-circular notch or an arc-shaped notch with the opening facing downwards.

[0097] Continue to refer to Figure 8 In one embodiment, along Figure 8In the vertical direction z shown, the surface of the second rod 312 facing the cleaning device, i.e., the upper surface, is higher than the upper surface of the first rod 311, to provide space for the setting of the second notch 314.

[0098] In the arrangement direction of the two sets of drive mechanisms 30, that is, along Figure 8 In the y-direction shown, the first rod 311 and the second rod 312 of each drive rod 31 are offset. Since the second rod 312 requires a second notch 314 for the first connecting rod 32 to pass through, the second rod 312 and the first rod 311 are offset to reserve space for the second railing in the y-direction. Between the two drive rods 31 of the two sets of drive mechanisms 30, in the y-direction, the distance between the outer surfaces of the two second rods 312 is greater than the distance between the outer surfaces of the two first rods 311.

[0099] To ensure a high connection strength between the first rod 311 and the second rod 312, a first reinforcing plate 313 is provided between the first rod 311 and the second rod 312. The first reinforcing plate 313 can be disposed on the upper surface of the second rod 312 and extend to the edge of the upper surface of the first rod 311, connecting with the first rod 311.

[0100] By setting the first reinforcing plate 313, the connection strength between the first rod 311 and the second rod 312 can be improved, preventing the second rod 312 from breaking when subjected to force.

[0101] Figure 9 A side view schematic diagram of the connection structure between the drive rod and the sealing plate is shown. (Refer to...) Figure 9 The first end of the drive rod 31 is inclinedly connected to the surface of the sealing plate 20, that is, the angle α between the extension direction of the drive rod 31 and the surface of the sealing plate 20 is less than 90°.

[0102] Refer to together Figures 3 to 9 When the sealing plate 20 is in the first position, i.e., when it is covering the first notch 122, its covering surface needs to mate with the ramp 12 to avoid affecting the movement of the cleaning device 200. Therefore, the sealing plate 20 needs to be tilted when it is covering the first notch 122. Thus, the angle α between the drive rod 31 and the sealing plate 20 is the same as or similar to the slope of the ramp 12, such as the angle difference being controlled within 10°, 5°, or 3°. Therefore, the tilted connection between the drive rod 31 and the sealing plate 20 facilitates the setting of the drive mechanism 30 and simplifies its structure.

[0103] Figure 10 This is a schematic diagram of the drive rod and drive unit according to one embodiment. Figure 11 This is a schematic diagram of the structure of the drive unit according to one embodiment. Figure 10 and Figure 11 As shown, in one embodiment, the drive unit 301 further includes a linkage assembly. One end of the linkage assembly can serve as an output end and is rotatably connected to the drive rod 31. The other end of the linkage assembly is suspended and can serve as a contact end M of the drive assembly. When the contact end M is pressed and moves along a first direction, the output end of the linkage assembly can move in the opposite direction of the first direction. The linkage assembly has a second rotation center G2. When the contact end M of the linkage assembly is pressed and moves along the first direction, the linkage assembly can rotate around the second rotation center G2 and drive the output end to move in the opposite direction of the first direction. By using the linkage assembly as the drive unit, the structure of the drive unit can be reduced, and the drive rod can be driven only through structural components, reducing the use of electrical drive components.

[0104] In this embodiment, one end of the linkage assembly is located in the second notch 314 of the drive rod 31, and the other end is provided with a pressing member 34. In one embodiment, the pressing member 34 includes a roller 35, which is rotatably connected to the other end of the linkage assembly.

[0105] For example, the following combination Figure 10 and Figure 11 The linkage assembly of this application will be described in further detail. For example... Figure 10 and Figure 11 As shown, in one embodiment, the linkage assembly in the drive unit 301 includes a first linkage 32 and a second linkage 33. The first end of the first linkage 32 serves as the output end and is rotatably connected to the drive rod 31. The second end of the first linkage 32 and the first end of the second linkage 33 are rotatably connected to form the second rotation center G2. The second end of the second linkage 33 is the contact end M. The linkage assembly consisting of the first linkage 32 and the second linkage 33 can realize the function of the drive unit, resulting in a simpler drive structure.

[0106] Reference Figure 10 and Figure 11 The first end of the first link 32 is connected to the middle region of the drive rod 31 and can drive the drive rod 31 to rotate around the first rotation center G1. The second end of the first link 32 is rotatably connected to the first end of the second link 33.

[0107] The first end of the first connecting rod 32 is connected to the middle part of the drive rod 31, and the first end of the first connecting rod 32 can be used to drive the drive rod 31 to rotate. The second end of the first connecting rod 32 is connected to the first end of the second connecting rod 33, and the second end of the second connecting rod 33 is the contact end M. When the contact end M is subjected to force, the second connecting rod 33 can drive the first connecting rod 32 to move, the first connecting rod 32 drives the drive rod 31 to move, and the drive rod 31 drives the sealing plate 20 to move.

[0108] By using the drive rod 31, the first connecting rod 32 and the second connecting rod 33 to form the drive mechanism 30, and the second end of the second connecting rod 33 as the pressing end M, the structural setting of the drive mechanism 30 can be simplified. The linkage can be achieved by applying pressure to the pressing member 34, thereby driving the sealing plate 20 to move.

[0109] Continue to refer to Figure 10 and Figure 11 In one implementation, the first link 32 includes a third link 321 and a fourth link 322 fixedly connected. The third link 321 and the fourth link 322 form an L-shaped structure. The third link 321 is inserted into the second notch 314, and the fourth link 322 is rotatably connected to the second link 33. The third link 321 may be a cylindrical link, allowing it to rotate relative to the second link 312 when inserted into the second notch 314.

[0110] The first link 32 serves as the transmission link between the drive link 31 and the second link 33. It is configured as an L-shaped structure, which simplifies the structural setup of the drive assembly.

[0111] Similarly, a second reinforcing plate 323 can be provided between the third rod 321 and the fourth rod 322. By providing the second reinforcing plate 323, the connection strength between the third rod 321 and the fourth rod 322 can be improved, preventing the third rod 321 and the fourth rod 322 from breaking when subjected to force.

[0112] The connection point formed by the rotatable connection between the fourth rod 322 and the second connecting rod 33 is the second rotation center G2, which is not connected to other components. When the second connecting rod 33 is subjected to force and moves downward, the position of the second rotation center G2 can change accordingly, driving the third rod 321 to move upward, thereby causing the drive rod 31 to rotate.

[0113] Continue to refer to Figure 10 and Figure 11 In one embodiment, the second end of the second connecting rod 33, i.e., the pressing end M, is provided with a pressing member 34. When the pressing member 34 is in a free state, i.e., without pressure, the sealing plate 20 is in a first position state, covering the first notch. When the pressing member 34 is pressed, the driving mechanism drives the sealing plate 20 to cover the main brush port of the cleaning device. The driving part is activated by pressing, thereby driving the sealing plate to switch between two position states.

[0114] Reference Figure 4 and Figure 5Since the driving mechanism is located at the bottom of the ramp plate 12, in order to achieve the pressing of the pressing member 34, in one embodiment, a third notch 123 is provided at the top of the ramp plate 12. The pressing member 34 may be located at the third notch 123. Figure 12 In one embodiment, the contact element in the ramp slab ( Figure 4 A magnified structural diagram of point D in the middle. Figure 12 As shown, the pressure-sensitive element 34 protrudes from the third notch 123. The third notch 123 is positioned corresponding to the location of the drive wheel when the cleaning device is parked on the ramp. Because the third notch 123 corresponds to the drive wheel, when the drive wheel of the cleaning device reaches the position of the pressure-sensitive element 34, the drive mechanism is triggered, and pressure is applied to the pressure-sensitive element 34 by the drive wheel.

[0115] The second end of the second link 33 can protrude from the third notch 123 to form a pressing element 34.

[0116] Refer to together Figures 10 to 12 In one embodiment, the pressure member 34 includes a roller 35, which is rotatably connected to the second connecting rod 33. The roller 35 protrudes from the third notch 123 to form the pressure member 34. By providing the roller 35 as the pressure member 34 at the second end of the second connecting rod 33, the friction between the drive wheel of the cleaning device and the pressure member 34 can be reduced, thereby improving the service life of the drive mechanism.

[0117] To facilitate the installation of the roller 35, in one embodiment, a groove can be provided at the second end of the second connecting rod 33, and the roller 35 is disposed in the groove. By providing the groove, clamping portions can be added on both sides of the roller 35 in the axial direction, thereby increasing the stability of the roller 35 connection.

[0118] Because the roller 35 rotates relative to the drive wheel 201 of the cleaning device 200 when it comes into contact, the friction between the drive wheel 201 and the pressure member 34 can be reduced.

[0119] Refer to together Figures 1 to 12 In the base station assembled using the ramp plate of this application embodiment, when the drive wheel 201 of the cleaning device 200 travels to the position of the third notch 123, the drive wheel 201 applies pressure to the contact pressing member 34. After the contact pressing member 34 is pressed, the drive mechanism 30 drives the sealing plate 20 to move towards the cleaning device 200, such as... Figure 5 As shown. When the drive wheel 201 of the cleaning device 200 leaves the position of the third notch 123, and the pressing member 34 returns to its free state, the sealing plate 20 covers the first notch 122, as shown. Figure 4 As shown.

[0120] In this embodiment, the sealing plate 20 can return to its first position state using its own gravity. To ensure that the sealing plate 20 can smoothly return to its first position state after the cleaning device leaves, a reset member can be provided between the sealing plate 20 and the bracket located at the bottom of the sealing plate, or a reset member, such as a return spring, can be provided between the drive rod and the bracket located at the bottom of the drive rod. When the sealing plate 20 is in the first state, the reset member is in a stored state to provide a restoring force for the sealing plate to return to the second state.

[0121] For the same technical purpose, embodiments of this application also provide a base station. Figure 13 This is a schematic diagram of a base station structure. (Example) Figure 13 As shown, the base station 100 includes a base station body 101 and a ramp 10 of this application disposed within the base station body 101. The ramp 10 is located at the bottom of the base station body 101 and can serve as the base of the base station. The ramp 10 can be fixedly connected to the base station body 101 or detachably connected to the base station body 101.

[0122] For the same technical purpose, embodiments of this application provide a cleaning system, referring to... Figure 1 The cleaning system includes a cleaning device 200 and a base station 100 as described in this application. The cleaning device 200 is placed inside the base station 100.

[0123] Refer to together Figures 1 to 5 The bottom of the cleaning device 200 is equipped with a drive wheel 201 and a main brush port 206. When the cleaning device 200 is placed on the base station 100, the drive wheel 201 stops at the third notch 123 of the ramp plate 10 and applies pressure to the contact member 34; after the contact member 34 is pressed, the drive assembly drives the sealing plate 20 to move closer to the cleaning device 200 and cover the main brush port 206. After the drive wheel 201 leaves the third notch 123, the contact member 34 bounces up, and the sealing plate 20 returns to the first position under its own gravity, covering the first notch 122.

[0124] In one embodiment, the sealing plate 20 has a curved surface structure, and the edge of the sealing plate 20 can cover the main brush opening 206. The middle area of ​​the top surface of the sealing plate 20 can be a recessed area to prevent damage to the main brush 205 when the main brush opening 206 is fastened.

[0125] For the same technical purpose, this application provides a dust collection method, referring to... Figures 1 to 12This dust collection method is used for a cleaning device 200 and a base station 100. The base station 100 is used to park the cleaning device 200 and includes a ramp 10 with a sealing plate 20 on it. The dust collection method includes: when the drive wheel 201 of the cleaning device 200 is in a preset position on the ramp 10, the sealing plate 20 seals the main brush port 206 of the cleaning device 200. In some embodiments, the preset position may be a charging position, a self-cleaning position, or a dust collection position of the cleaning device, etc.

[0126] The ramp 10 has a pressure-sensitive element 34 at a preset position. When the drive wheel 201 applies pressure to the pressure-sensitive element 34, the sealing plate 20 seals the main brush port 206 of the cleaning device 200. When the drive wheel 201 leaves the preset position, the sealing plate 20 returns to the ramp 10.

[0127] In one embodiment, after the sealing plate 20 seals the main brush port 206 of the cleaning device 200, the dust collection method further includes: starting the dust collection fan of the base station 100, the dust collection fan forming a dust collection airflow in the cleaning device 200, the dust collection airflow passing through the filter screen 203 of the cleaning device and then flowing to the dust collection component of the base station 100.

[0128] In one embodiment, using the cleaning system to collect dust from the cleaning device may include: after the sealing plate 20 covers the main brush port 206 of the cleaning device 200, starting the dust collection fan of the base station 100, the dust collection fan forming a dust collection airflow within the cleaning device 200, the dust collection airflow flowing from the suction fan 202 side of the cleaning device 200 through the filter screen 203 and dust box 204 of the cleaning device before flowing to the dust collection component of the base station 100.

[0129] For example, the above dust collection may include the following steps:

[0130] Place the cleaning device 200 inside the base station, so that the drive wheel 201 presses down on the contact element 34, and the sealing plate 20 covers the main brush port 206; start the dust collection fan inside the base station 100, and the dust collection fan and the dust collection chamber of the cleaning device are in an air circuit connection state, and dust collection is achieved by the dust collection airflow formed by the dust collection fan in the cleaning device 200.

[0131] The dust-collecting airflow flows from the vent 207 of the cleaning device 200, sequentially passing through the vacuum fan, the filter 203, and the dust collection chamber within the cleaning device 200, before flowing to the dust collection component of the base station. The vent 207 of the cleaning device serves as the exhaust port for the vacuum fan. During the vacuuming process of the cleaning device 200, the airflow within the cleaning device 200 is discharged through the vent 207.

[0132] The dust collection fan can be started manually or automatically. For example, it can start automatically after the cleaning device is connected to the base station.
