Description

Technical Field

[0001] The present application relates to the technical field of lawn mowing equipment, and in particular to a lawn mower base station. Background Art

[0002] With the development of smart device technology, smart lawn mowers have gradually been widely used. Lawn mowers can replace manual labor to trim and cut the lawn in a predetermined area. The lawn mower can autonomously control the walking route and working area. Usually, in order to facilitate the docking and charging of the lawn mower, a lawn mower base station will be set up. The lawn mower can automatically enter or leave the lawn mower base station. In order to meet different application scenarios and add practical functions, the lawn mower is provided with sensors, such as camera modules. However, since lawn mowers are usually used in outdoor environments, objects such as dust, grass clippings, and mud will cover the outer surface of the sensor during the use of the lawn mower. When the accumulation of these objects is large, the working performance of the sensor will be significantly reduced, thereby affecting the normal operation of the sensor.

[0003] The Chinese utility model patent application number 202222059102.3 discloses a self-moving system with a nozzle, which is provided with a first nozzle assembly and a second nozzle assembly on a base station. The first nozzle assembly and the second nozzle assembly are used to spray cleaning liquid on the lens of the self-moving device to clean the lens. For the application scenario of the lawn mower, the above structure has the following defects: (1) The cleaning liquid will remain on the surface of the lens. Before the cleaning liquid on the lens surface is completely evaporated, it will affect the clarity of the lens field of view, and the lawn mower cannot work normally, affecting the working efficiency of the lawn mower. (2) The working environment of the lawn mower is outdoor grass. During the operation, the mud splashed onto the surface of the lens and mixed with rainwater will firmly adhere to the surface of the lens. It is difficult to separate the mud from the lens by a single spraying method, or a large amount of spraying is required to remove the mud from the surface of the lens.

[0004] The Chinese utility model patent with application number 202221914801.5 discloses a self-cleaning structure of a lawn mower and its visual system, wherein the visual system includes a camera system and a lens transparent plate, and a cleaning device is installed on the lawn mower and the housing, and the lens transparent plate is cleaned by moving the cleaning device on the lens transparent plate. The above structure has the following defects: the cleaning device is fixedly installed on the housing, and after a certain length of time of cleaning work, the surface of the cleaning device will be contaminated by dirt, affecting the cleaning effect. When cleaning the cleaning device, the cleaning device needs to be removed from the housing, and the cleaning and disassembly work is complicated.

[0005] In summary, in the prior art, for cleaning the lens of a lawn mower, there are problems such as poor cleaning effect, affecting the working efficiency of the lawn mower, and being unable to clean the cleaning device immediately. Utility Model Content

[0006] The embodiment of the present application provides a lawn mower base station, which can be helpful for cleaning the sensor so that the sensor maintains good working performance.

[0007] In a first aspect, an embodiment of the present application provides a lawn mower base station for docking a lawn mower. The lawn mower base station includes a base station body and a cleaning device.

[0008] The base station body includes a lawn mower parking position. The cleaning device is arranged on the base station body. The cleaning device includes a driver, a wiping assembly, and a medium supply unit. The driver is connected to the base station body. The wiping assembly is connected to the driver.

[0010] The medium supply unit of the embodiment of the present application can be used to perform at least two actions of spraying the target to be cleaned, wetting the wiping unit, drying the target to be cleaned, and drying the wiping unit. Specifically, it includes:

[0011] The first action mode: the medium supply unit can perform two actions: spraying the target to be cleaned and wetting the wiping unit; first, when the lawn mower enters the lawn mower base station, the medium supply unit sprays the surface of the sensor (target to be cleaned) to wash away the dirt on the sensor surface that is easy to wash away, and wets the dirt that is difficult to wash away; then, while spraying the sensor, the medium supply unit wets the wiping unit, and wipes the sprayed sensor with the wetted wiping unit to wipe away the dirt on the sensor surface that is difficult to wash away; then, the sensor is sprayed again to wash away the sewage remaining on the sensor surface after wiping; finally, after the lawn mower leaves the lawn mower base station, the medium supply unit wets and rinses the wiping unit separately to keep the surface of the wiping unit clean and prepare for the next cleaning work.

[0012] This mode has the following technical effects: the medium supply part and the wiping part work together to clean the sensor by wet wiping and spraying, which can greatly improve the cleaning effect and cleaning efficiency of the sensor compared to the single spray cleaning method; in addition, since the cleaning device is arranged on the lawn mower base station, after the lawn mower leaves the lawn mower base station, the wiping part can be cleaned separately without affecting the operation of the lawn mower, thereby keeping the wiping part in a clean state at all times and improving the cleaning effect.

[0013] The second action mode: the medium supply unit can perform two actions: drying the target to be cleaned and drying the wiping unit; first, in a rainy environment or other harsh working environment, the lawn mower returns to the lawn mower base station, and the wiping unit wipes the water stains on the surface of the sensor, removing most of the water stains on the surface of the sensor; then, the medium supply unit dries the surface of the sensor to completely remove the water stains on the surface of the sensor; finally, the wiping unit is dried to keep the surface of the wiping unit dry and ready for the next cleaning work.

[0029] In some achievable embodiments, the wiping assembly includes a receiving space, the receiving space has a first opening, the first opening is arranged facing the parking position of the lawn mower, and the wiping portion is arranged in the receiving space.

[0030] The wiping assembly includes a accommodating space, and the wiping part is arranged in the accommodating space. The shape of the wiping part is adapted to the shape of the accommodating space, and the thickness of each part of the wiping part can be kept uniform, thereby improving the wetting, cleaning and drying effects of the wiping part, thereby improving the cleaning effect of the wiping part on the sensor.

[0031] In some achievable ways, the wiping assembly includes a supporting member and a wiping member. The supporting member is connected to the driver. The supporting member has a containing space. The wiping member is connected to the supporting member. The wiping member has a wiping portion.

[0032] The support member can be a rigid structural member, so that it has good mechanical strength and is not easily deformed when subjected to force. During the wiping and cleaning process, the support member can provide good support for the wiping member to ensure that the wiping member always maintains a good fit and contact with the outer surface of the sensor protruding housing, thereby reducing the possibility of poor wiping and cleaning effects due to poor fit between the wiping member and the outer surface of the sensor protruding housing.

[0033] In some achievable embodiments, the medium supply unit includes a medium introduction pipe for introducing liquid medium and / or gaseous medium to perform at least two actions of spraying the target to be cleaned, wetting the wiping unit, drying the target to be cleaned, and drying the wiping unit.

[0034] Liquid medium and / or gaseous medium can be introduced through one medium introduction pipe, which is beneficial to reducing the number of medium introduction pipes to be set, reducing the difficulty of installing the medium introduction pipe on the base station body and reducing costs.

[0035] In some practicable ways, the medium introduction pipe is connected to the water supply mechanism. The medium supply part is used to perform two actions: spraying the target to be cleaned and wetting the wiping part.

[0036] The medium supply part can spray liquid on the surface of the sensor to remove the stains on the sensor surface that are easy to wash, and the wiping part supplies liquid to wet the wiping part, so that the wiping part is in a wet state. After the wiping part is humidified, the driver is started. The driver drives the wiping part in a wet state to wipe and clean the outer surface of the sensor protruding from the housing, thereby improving the cleaning efficiency and cleaning effect.

[0037] After the wiping assembly finishes cleaning the sensor, the mower leaves the mower base station. The medium supply unit can supply an appropriate amount of liquid to the wiping unit to rinse and clean the wiping unit, thereby removing dirt on the wiping unit, and the driver can drive the wiping unit to move and spin dry the wiping unit, so that the wiping unit itself maintains a good cleanliness.

[0038] In some achievable embodiments, the water supply mechanism is disposed inside the base station body. The water supply mechanism includes a liquid storage tank and a liquid supply pipeline. The liquid supply pipeline connects the liquid storage tank and the medium introduction pipeline.

[0042] In some practicable manners, the medium introduction pipeline is connected to the air source supply mechanism. The medium supply unit is used to perform two actions: drying the object to be cleaned and drying the wiping unit.

[0043] The medium supply part can blow hot air to the wiping part and the outer surface of the sensor protruding shell. When oil and other dirt are adhered to the outer surface of the sensor protruding shell, the hot air blown by the medium supply part can heat the oil and other dirt on the outer surface of the sensor protruding shell to improve the fluidity of the oil and other dirt, thereby reducing the difficulty of the wiping member to wipe off the oil and other dirt, and improving the cleaning efficiency and cleaning effect.

[0044] After the wiping assembly finishes cleaning the sensor, the medium supply unit can blow hot air to the wiping unit to heat the wiping unit, thereby drying the wiping unit and keeping the wiping unit dry, which is beneficial to reduce the possibility of the wiping unit becoming moldy and producing odor due to the wiping unit being in a wet state.

[0045] After the wiping assembly finishes cleaning the sensor, the medium supply unit can blow hot air toward the sensor to dry the outer surface of the sensor, thereby preventing residual liquid on the outer surface of the sensor from affecting the normal operation of the sensor.

[0046] In some achievable ways, the air supply mechanism is arranged inside the base station body. The air supply mechanism includes a fan and a ventilation duct. The ventilation duct is connected to the medium introduction duct, and the fan is arranged in the ventilation duct.

At least a part of the channel holes are connected to the corresponding flow channel holes, and the channel holes are evenly distributed on the surface of the support member, and the flow channel holes are evenly distributed on the surface of the flow channel hole.

[0051] The connected channel holes and flow channel holes can simultaneously allow liquid and / or gas to flow through the channel holes and the flow channel holes, and can be discharged from the flow channel holes, so that the medium supply part can perform at least two actions of wetting the wiper, drying the wiper, spraying the sensor, and drying the sensor. In addition, the flow channel holes and the channel holes are arranged on the support member and the wiping part, and liquid can be sprayed onto the surface of the sensor from various angles, thereby improving the efficiency of spray cleaning.

[0052] In some achievable embodiments, the adapter mechanism includes a sleeve. The sleeve has a cavity. The medium introduction pipe is connected to the sleeve. The medium introduction pipe is connected to the cavity. The wiping assembly also includes an adapter shaft. The adapter shaft is connected to the support member.

[0053] In some achievable modes, the medium introduction pipe is sealedly connected to the sleeve, the adapter shaft is sealedly connected to the sleeve, and the adapter shaft is sealedly connected to the support member.

[0054] The medium introduction pipe is sealed and connected to the sleeve, which is conducive to avoiding the problem of liquid leakage or gas leakage between the medium introduction pipe and the sleeve. The adapter shaft is sealed and connected to the sleeve, which is conducive to avoiding the problem of liquid leakage or gas leakage between the adapter shaft and the sleeve. The adapter shaft is sealed and connected to the support, which is conducive to avoiding the problem of liquid leakage or gas leakage between the adapter shaft and the support.

[0055] In some possible implementations, the number of the channel holes is greater than the number of the flow channel holes.

[0056] A portion of the channel holes are connected to the corresponding flow channel holes, and another portion of the channel holes are blocked and covered by the wiper.

[0057] The connected channel holes and flow channel holes can simultaneously allow liquid and / or gas to flow through the channel holes and the flow channel holes, and be discharged from the flow channel holes into the accommodation space. For example, the liquid discharged from the flow channel holes can spray the sensor. At the same time, the liquid or gas can be directly transported to the wiper through the channel holes covered by the wiper to wet the wiper or dry the wiper. Therefore, the cleaning device can simultaneously realize the function of spraying the sensor and the function of wetting the wiper.

[0058] In some achievable manners, each flow channel hole is connected to the channel hole. Each flow channel hole can be used to realize the function of spraying or drying the sensor.

[0059] In some achievable embodiments, the number of the channel holes is less than or equal to the number of the flow channel holes. The diameter of the flow channel hole is greater than the diameter of the channel hole. The entire area of ​​each channel hole is connected to the flow channel hole.

[0060] In a manner where the diameter of the flow channel hole is larger than the diameter of the channel hole, the cleaning device can perform the function of spraying the sensor and the function of drying the sensor. The liquid discharged from the channel hole may not wet the wiper.

[0061] In some achievable embodiments, the diameter of the flow channel hole is smaller than or equal to the diameter of the channel hole.

[0062] In such a way that the diameter of the flow channel hole is smaller than or equal to the diameter of the channel hole, the cleaning device can realize the function of the spray sensor and the function of the wetting wiper.

[0064] In some achievable ways, the support member includes a cover body, the cover body is connected to the driver, the cover body has a receiving space, and the wiper is arranged on the cover body.

[0065] The part of the sensor located inside the cover can be shielded by the cover. When the driver drives the cover and the wiping piece to rotate, the wiping part of the wiping piece can wipe and clean the part of the sensor located inside the cover.

[0066] In some feasible embodiments, the wiper is located in the accommodating space.

[0067] In some practicable embodiments, the wiper and the cover body are detachably connected to facilitate maintenance or replacement of the wiper.

[0072] The middle area of ​​the arc-shaped support arm is connected to the drive.

[0073] In some practicable embodiments, the wiper is a flexible structural member.

[0074] The wiping piece is compressed and deformed under the action of the squeezing force, so that the wiping piece can maintain a good fit with the outer surface of the sensor protruding shell, to ensure that the wiping piece can effectively wipe and clean the outer surface of the sensor protruding shell.

[0075] The wiping piece is a flexible structural piece, so that when the wiping piece wipes and cleans the outer surface of the sensor protruding housing, the wiping piece is not likely to scratch the outer surface of the sensor protruding housing.

[0076] In some practicable embodiments, the wiper is a water-absorbing structure.

[0077] Before the wiper wipes and cleans the sensor, the wiper can be humidified with water to make the wiper itself wet.

[0131] Figure 1 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 2 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 1 and Figure 2 As shown, the lawn mower base station 10 of the embodiment of the present application can be used for the lawn mower to dock. After completing the corresponding mowing task, the lawn mower can automatically return to the lawn mower base station 10 for docking. When the lawn mower is needed to perform the mowing task again, the lawn mower can automatically leave the lawn mower base station 10.

[0132] In some achievable ways, the lawn mower base station 10 of the embodiment of the present application can be used to charge and replenish the lawn mower so that the power of the lawn mower itself is maintained within a reasonable range. When the power of the lawn mower itself is lower than the threshold, the lawn mower can automatically enter the lawn mower base station 10 for charging. After charging is completed, the lawn mower can automatically leave the lawn mower base station 10. Therefore, during the process of charging using the lawn mower base station 10, the lawn mower is relatively less dependent on manual operation, and does not require excessive manual intervention, which effectively improves the convenience of using the lawn mower.

[0133] The lawn mower base station 10 of the embodiment of the present application may include a base station body 20. The base station body 20 includes a lawn mower parking position 20a. The lawn mower parking position 20a of the base station body 20 is used to facilitate the lawn mower to enter or leave the lawn mower base station 10. For example, when the lawn mower base station 10 is used to charge and replenish energy for the lawn mower, when the lawn mower needs to return to the lawn mower base station 10 for charging, the lawn mower enters the lawn mower parking position 20a. After the lawn mower travels a predetermined distance, the charging electrode of the lawn mower contacts the docking electrode of the lawn mower base station 10. After the charging electrode and the docking electrode are docked, the docking electrode is powered on, thereby outputting electrical energy to the charging electrode. After the lawn mower completes charging, the lawn mower leaves the lawn mower parking position 20a and drives out of the lawn mower base station 10.

[0134] Figure 3 The partial structure of a lawn mower 100 according to an embodiment of the present application is schematically shown. Figure 3 As shown, the lawn mower 100 of the embodiment of the present application may include a housing 110 and a sensor 120. The sensor 120 is disposed on the housing 110. The housing 110 includes a top surface 111 and a side surface 112. The sensor 120 has an outer surface protruding from the housing 110. The outer surface of the sensor 120 refers to a surface on the sensor 120 that protrudes from the housing 110 and is in a visible state.

[0135] In some examples, the sensor 120 may include a light-transmitting portion 121. The light-transmitting portion 121 of the sensor 120 is exposed to the housing 110, so that the housing 110 does not block the light-transmitting portion 121, so as to ensure that the light-transmitting portion 121 has good light transmittance. The outer surface of the light-transmitting portion 121 may be the outer surface of the sensor 120 protruding from the housing 110. The outer surface of the light-transmitting portion 121 faces the external environment. The light-transmitting portion 121 has a light-transmitting function and can provide protection for other light receiving components in the sensor 120.

[0136] In some achievable ways, the light-transmitting portion 121 may be disposed on the top surface 111 of the housing 110. In the vertical direction, the light-transmitting portion 121 is disposed on the upward surface of the housing 110. Alternatively, the light-transmitting portion 121 may be disposed on the side surface 112 of the housing 110. The side surface 112 of the housing 110 refers to a surface that intersects with the vertical direction but is not perpendicular to each other. The side surface 112 of the housing 110 may be connected to the top surface 111 of the housing 110.

[0137] In some achievable ways, the light-transmitting portion 121 may be a transparent structural member, which is helpful to ensure that the light-transmitting portion 121 has good light transmittance. In some examples, the material of the light-transmitting portion 121 may be, but is not limited to, plastic or glass. The outer surface of the light-transmitting portion 121 facing the external environment may be protruding from the outer surface of the housing 110.

[0138] In some achievable ways, the sensor 120 may include at least one of a camera module, an optical distance sensor, and a light sensor. The camera module is used to collect images of the external environment so that the lawn mower 100 can sense the external environment through the camera module. For example, the lawn mower 100 can perform obstacle avoidance actions or route planning through the images obtained by the camera module. The optical distance sensor is used to detect the distance between the lawn mower 100 and the surrounding objects. For example, when the lawn mower 100 returns to the lawn mower base station 10, the lawn mower 100 can detect the distance between the lawn mower 100 and the lawn mower base station 10 through the optical distance sensor to ensure that the lawn mower 100 accurately reaches the predetermined parking position, which is conducive to avoiding a collision between the lawn mower 100 and the lawn mower base station 10. The light sensor is used to detect changes in brightness of the external environment. For example, the lawn mower 100 can determine the weather conditions of the current external environment through the light sensor to choose to execute the mowing task or standby according to the current weather conditions. In the embodiment of the present application, the sensor 120 may also be other devices besides the devices listed above, and the embodiment of the present application does not limit the specific type of the sensor 120.

[0139] Since the working environment of the lawn mower 100 is usually an outdoor environment, the outer surface of the sensor 120 protruding from the housing 110 is directly exposed to the external environment. During the use of the lawn mower 100, dust or oil from the external environment, grass clippings generated during mowing, or mud mixed in rainy and snowy days will fall on the outer surface of the sensor 120 protruding from the housing 110 and adhere to the outer surface of the sensor 120 protruding from the housing 110, thereby blocking the outer surface of the sensor 120 protruding from the housing 110, thereby affecting the normal operation of the sensor 120.

[0140] Figure 4 The partial structure of the lawn mower 100 docked at the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figures 2 to 4As shown, the base station of the embodiment of the present application also includes a cleaning device 30. The cleaning device 30 is arranged on the base station body 20. The cleaning device 30 includes a driver 40 and a wiping assembly 50. The driver 40 is connected to the base station body 20. The wiping assembly 50 is connected to the driver 40. The wiping assembly 50 includes a wiping portion 50a. The wiping portion 50a itself has a wiping concave surface. The wiping concave surface can be a curved surface, for example, the wiping concave surface can be a spherical surface. The wiping portion 50a in the wiping cleaning position is arranged with the wiping concave surface facing the lawn mower parking position 20a. The wiping concave surface of the wiping portion 50a can be adapted to the shape of the outer surface of the sensor 120 protruding from the shell 110, so that when the wiping concave surface is in contact with the outer surface of the sensor 120 protruding from the shell 110, the wiping concave surface can be well fitted with the outer surface of the sensor 120 protruding from the shell 110. The driver 40 is used to drive the wiping assembly 50 to move, so that the wiping portion 50 a of the wiping assembly 50 performs a wiping cleaning action to clean the target to be cleaned. The target to be cleaned may refer to the sensor 120 of the lawn mower 100 .

[0141] When the outer surface of the sensor 120 protruding from the housing 110 is blocked by dirt, the lawn mower 100 can return to the lawn mower base station 10. The lawn mower 100 enters the lawn mower parking position 20a. After the lawn mower 100 moves to the predetermined position, the lawn mower 100 stops moving. The wiping portion 50a of the wiping assembly 50 can be set corresponding to the sensor 120. Exemplarily, the wiping portion 50a of the wiping assembly 50 can refer to a portion used to fit and contact with the outer surface of the sensor 120 protruding from the housing 110.

[0142] The wiping portion 50a in the wiping and cleaning position can maintain a close contact state with the outer surface of the sensor 120 protruding from the housing 110. The driver 40 is started, and the wiping assembly 50 moves relative to the sensor 120 under the drive of the driver 40. The wiping portion 50a of the wiping assembly 50 can wipe and clean the sensor 120 to clean dust, grass clippings, mud and other dirt attached to the outer surface of the sensor 120 protruding from the housing 110, so that the outer surface of the sensor 120 protruding from the housing 110 is kept clean, thereby ensuring the normal operation of the sensor 120. After the sensor 120 of the lawn mower 100 is cleaned, the lawn mower 100 can leave the lawn mower parking position 20 to perform related tasks.

[0143] The lawn mower base station 10 of the embodiment of the present application can be used for the lawn mower 100 to dock. The lawn mower base station 10 includes a cleaning device 30. When the lawn mower 100 is in use, if the sensor 120 is contaminated and the working performance is reduced, the lawn mower 100 can be docked at the lawn mower parking position 20a. Then, the cleaning device 30 on the lawn mower base station 10 can be used to clean the sensor 120 on the lawn mower 100. The wiping concave surface of the wiping portion 50a can be in contact with the outer surface of the protruding housing 110 of the sensor 120 to wipe and remove the dirt on the sensor 120, so that the sensor 120 is kept clean to maintain good working performance. Therefore, the lawn mower base station 10 of the embodiment of the present application can clean the sensor 120 on the lawn mower 100 to ensure that the sensor 120 of the lawn mower 100 works normally.

[0144] In the present application examples, see Figures 2 to 4 As shown, the wiping assembly 50 may include a receiving space 50b. The receiving space 50b has a first opening. When the wiping assembly 50 is in the wiping cleaning position, the first opening of the receiving space 50b can be arranged facing the lawn mower parking position 20a. The wiping concave surface of the wiping portion 50a can be arranged facing the lawn mower parking position 20a. The wiping portion 50a is arranged in the receiving space 50b. In some embodiments, at least part of the wiping portion 50a can be located in the receiving space 50b. The wiping concave surface of the wiping portion 50a can be located in the receiving space 50b.

[0145] In some embodiments, the sensor 120 includes a light-transmitting portion 121. The light-transmitting portion 121 of the sensor 120 in the lawn mower 100 is disposed protruding from the housing 110. The protruding light-transmitting portion 121 can have a relatively large light-entering area, so that the light-transmitting portion 121 can obtain a higher amount of light entering, and it is also helpful to reduce the possibility of the light-transmitting portion 121 being completely blocked.

[0146] In some embodiments, the shape of the sensor 120 protruding from the outer surface of the housing 110 can be hemispherical, which is not specifically limited in the embodiments of the present application.

[0147] The accommodating space 50b of the wiping assembly 50 can be used to accommodate the outer surface of the sensor 120 protruding from the housing 110. When the wiping assembly 50 is in the wiping and cleaning position, the sensor 120 can enter the accommodating space 50b of the wiping assembly 50. The wiping concave surface of the wiping portion 50a can fit and contact with the outer surface of the sensor 120 protruding from the housing 110. When the wiping portion 50a fits and contacts with the outer surface of the sensor 120 protruding from the housing 110, the shape of the wiping portion 50a can match the outer shape of the outer surface of the sensor 120 protruding from the housing 110, thereby facilitating the increase of the contact area between the wiping portion 50a and the outer surface of the sensor 120 protruding from the housing 110, and then the wiping portion 50a can clean a larger area of ​​the outer surface of the sensor 120 protruding from the housing 110, which is conducive to improving the cleaning efficiency.

[0148] In some examples, the driver 40 may drive the wiper 50a to rotate or swing around the rotation axis S. When the shape of the sensor 120 protruding from the outer surface of the housing 110 is hemispherical, the rotation axis S of the wiper 50a may pass through the center of the sphere where the sensor 120 protrudes from the outer surface of the housing 110 .

[0149] In the embodiment of the present application, the wiping portion 50a in the wiping and cleaning position is arranged facing the lawn mower parking position 20a. In some embodiments, the wiping portion 50a in the wiping and cleaning position is located on the moving path of the sensor 120. After the lawn mower 100 enters the lawn mower parking position 20a, the sensor 120 on the lawn mower 100 can move toward the wiping portion 50a in the wiping and cleaning position. During the movement of the lawn mower 100, the sensor 120 can gradually approach the wiping portion 50a in the wiping and cleaning position. The lawn mower 100 continues to move, and the sensor 120 can gradually enter the accommodating space 50b from the first opening of the accommodating space 50b. After the lawn mower 100 travels to the predetermined position, the lawn mower 100 stops moving. At this time, at least part of the sensor 120 is located in the accommodating space 50b, and the outer surface of the sensor 120 protruding from the housing 110 is in contact with the wiping concave surface of the wiping portion 50a. The driver 40 is started, and the driver 40 drives the wiping assembly 50 to move relative to the sensor 120 to wipe and clean the outer surface of the sensor 120 protruding from the housing 110 .

[0150] In some embodiments, Figure 5 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 6 The partial structure of the lawn mower 100 docked at the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 5 and Figure 6As shown, the driver 40 can be mounted and fixed to the base station body 20. The position of the driver 40 relative to the base station body 20 is fixed. The wiping assembly 50 connected to the driver 40 is fixed relative to the base station body 20. The wiping assembly 50 is in a wiping and cleaning position. The wiping portion 50a of the wiping assembly 50 is located outside the base station body 20. Exemplarily, the wiping portion 50a of the wiping assembly 50 can be in a visible state.

[0151] The base station body 20 may include a side support portion 21 and a top support portion 22. The top support portion 22 is connected to the side support portion 21. The side support portion 21 is arranged corresponding to the lawn mower parking position 20a. The top support portion 22 is located above the lawn mower parking position 20a. The side support portion 21 is provided with a cleaning device 30. The housing 110 of the lawn mower 100 has a top surface 111 and a side surface 112. The side surface 112 of the housing 110 is provided with a sensor 120. The sensor 120 protrudes from the side surface 112 of the housing 110. After the lawn mower 100 enters the lawn mower parking position 20a and drives to a predetermined position, the lawn mower 100 stops moving. At least part of the sensor 120 is located in the accommodating space 50b formed by the support member, and the outer surface of the sensor 120 protruding from the housing 110 is in contact with the wiping concave surface of the wiping portion 50a. The driver 40 is started, and the driver 40 drives the wiping assembly 50 to move relative to the sensor 120 to wipe and clean the sensor 120 .

[0152] In other embodiments, Figure 7 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 8 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Figure 7 and Figure 8 As shown, the mower base station 10 may include a telescopic device 200. The driver 40 is disposed on the telescopic device 200. The telescopic device 200 can drive the driver 40 and the wiping assembly 50 to move relative to the base station body 20. For example, when the wiping assembly 50 is in a non-working state, the driver 40 and the wiping assembly 50 can be located inside the base station body 20. When the wiping assembly 50 is required to perform a wiping and cleaning action, the telescopic device 200 drives the driver 40 and the wiping assembly 50 to move so that the wiping assembly 50 extends out of the base station body 20 and finally reaches the wiping and cleaning position. After the wiping and cleaning work is completed, the telescopic device 200 drives the driver 40 and the wiping assembly 50 to move so that the wiping assembly 50 retreats to the inside of the base station body 20.

[0153] In some examples, the telescopic device 200 may be an electric cylinder or a pneumatic cylinder.

[0154] In some examples, before the lawn mower 100 enters the lawn mower parking position 20a, the wiping assembly 50 is moved to the wiping and cleaning position by the telescopic device 200. Then, the lawn mower 100 enters the lawn mower parking position 20a. The sensor 120 on the lawn mower 100 is docked with the wiping assembly 50, so that the outer surface of the sensor 120 protruding from the housing 110 is in contact with the wiping concave surface of the wiping portion 50a.

[0155] In other examples, the lawn mower 100 enters the lawn mower parking position 20a and completes the parking action. Then, the wiping assembly 50 is pushed out to the wiping cleaning position by the telescopic device 200. The wiping assembly 50 is docked with the sensor 120 on the lawn mower 100, so that the outer surface of the sensor 120 protruding from the housing 110 is in contact with the wiping concave surface of the wiping portion 50a.

[0156] In some possible implementations, see Figure 5 and Figure 6 As shown, the wiping assembly 50 includes a support member 51 and a wiping member 52. The support member 51 is connected to the driver 40. The support member 51 has a accommodating space 50b. The wiping member 52 is connected to the support member 51. The wiping member 52 has a wiping portion 50a. The wiping portion 50a of the wiping member 52 may refer to a portion used for fitting and contacting with the outer surface of the sensor 120 protruding from the housing 110. The support member 51 may be a rigid structural member, so that it has good mechanical strength and is not easily deformed when subjected to force. During the wiping and cleaning process, the support member 51 can provide good support for the wiping member 52 to ensure that the wiping member 52 always maintains a good fitting and contacting state with the outer surface of the sensor 120 protruding from the housing 110, thereby reducing the possibility of poor wiping and cleaning effects due to poor fitting between the wiping member 52 and the outer surface of the sensor 120 protruding from the housing 110.

[0157] In some embodiments, the support member 51 can be detachably connected to the driver 40, so as to facilitate disassembly, replacement or maintenance of the wiping assembly 50. The wiping member 52 can be detachably connected to the support member 51, so as to facilitate disassembly, replacement or maintenance of the wiping member 52.

[0173] In some examples, the shape of the arc-shaped support arm 512 may be adapted to the outer shape of the sensor 120 protruding from the outer surface of the housing 110. For example, the outer surface of the sensor 120 protruding from the housing 110 may be hemispherical. The shape of the arc-shaped support arm 512 may be an arc.

[0174] For example, see Fig.11 As shown, the middle area of ​​the arc-shaped support arm 512 can be connected to the driver 40. Exemplarily, the shape of the arc-shaped support arm 512 can be an arc with a central angle equal to 180°.

[0175] Exemplarily, one end of the arc-shaped support arm 512 is connected to the driver 40. The rotation axis S of the arc-shaped support arm 512 passes through the center of the arc-shaped support arm 512. Exemplarily, Fig.12 The partial structure of the wiping assembly 50 according to an embodiment of the present application is schematically shown. Fig.12 As shown, the shape of the arc-shaped support arm 512 can be an arc with a central angle equal to 90°.

[0176] In some achievable ways, the wiper 52 is a flexible structural member. The wiper 52 itself is flexible, and when subjected to a squeezing force, the wiper 52 itself can be compressed and deformed. For example, when the outer surface of the sensor 120 protruding from the housing 110 is in a state of fitting contact with the wiper 52, the sensor 120 and the support member 51 can jointly squeeze the wiper 52. The wiper 52 is compressed and deformed under the action of the squeezing force, so that the wiper 52 can maintain a good fit with the outer surface of the sensor 120 protruding from the housing 110, so as to ensure that the wiper 52 can effectively wipe and clean the outer surface of the sensor 120 protruding from the housing 110.

[0177] The wiping member 52 is a flexible structural member, so that when the wiping member 52 wipes and cleans the outer surface of the sensor 120 protruding from the housing 110 , the wiping member 52 is not likely to scratch the outer surface of the sensor 120 protruding from the housing 110 .

[0178] In some embodiments, the material of the wiper 52 may include at least one of leather, sponge, textile, fluff, paper, soft glue, synthetic fiber, and plant fiber. The present application embodiment does not specifically limit the material of the wiper 52. In some examples, the textile may be cloth. The soft glue may be rubber or silicone. The synthetic fiber may be synthetic wool.

[0179] In some embodiments, see Fig.11 or Fig.12 As shown, the support member 51 is an arc-shaped support arm 512. The flexible wiper 52 can be connected to the arc-shaped support arm 512. The sensor 120 can squeeze the flexible wiper 52 to deform the wiper 52, so that the wiper 52 is matched with the outer shape of the sensor 120 protruding from the outer surface of the housing 110.

[0180] In some achievable ways, the wiping member 52 is a flexible structural member. At the same time, the wiping member 52 is a water-absorbing structural member. The wiping member 52 is flexible and water-absorbing. Before the wiping member 52 wipes and cleans the sensor 120, the wiping member 52 can be humidified with water so that the wiping member 52 itself is in a wet state. When the wiping member 52 in a wet state wipes and cleans the sensor 120, the wiping member 52 can relatively easily wipe and remove the dirt on the outer surface of the sensor 120 protruding from the housing 110, which is conducive to improving the cleaning effect of the wiping member 52.

[0181] In some embodiments, the material of the wiper 52 may include at least one of sponge, textile, fluff, paper, synthetic fiber, and plant fiber. In some examples, the textile may be cloth. The synthetic fiber may be synthetic wool.

[0182] In some achievable ways, Fig.13 The partial structure of the wiping assembly 50 according to an embodiment of the present application is schematically shown. Fig.13 As shown, the wiping member 52 covers at least a portion of the supporting member 51. The wiping member 52 covers the supporting member 51 in such a manner that when the wiping member 52 is in close contact with the outer surface of the sensor 120 protruding from the housing 110, the wiping member 52 can isolate the supporting member 51 and the sensor 120, thereby reducing the possibility that the supporting member 51 directly contacts the sensor 120 and causes the supporting member 51 to scratch the outer surface of the sensor 120 protruding from the housing 110.

[0183] In some embodiments, the support member 51 includes an inner wall for cooperating with the outer surface of the sensor 120 protruding from the housing 110 and a side wall connected to the inner wall. The wiping portion 50a of the wiping member 52 is arranged corresponding to the inner wall. When the wiping assembly 50 is docked with the sensor 120, the outer surface of the sensor 120 protruding from the housing 110 and the inner wall of the support member 51 jointly squeeze the wiping member 52, so that the wiping portion 50a and the outer surface of the sensor 120 protruding from the housing 110 are in close contact. The side wall of the support member 51 is close to the sensor 120. The wiping member 52 can cover the inner wall of the support member 51 and the side wall of the support member 51, reducing the possibility that the side wall of the support member 51 contacts the sensor 120 and causes the support member 51 to scratch the outer surface of the sensor 120 protruding from the housing 110.

[0184] In some embodiments, Fig.14 The partial structure of the wiping assembly 50 according to an embodiment of the present application is schematically shown. Fig.14 As shown, the wiping member 52 can cover the entire supporting member 51, so that when the wiping member 52 is in close contact with the outer surface of the sensor 120 protruding from the shell 110, the wiping member 52 can effectively isolate the supporting member 51 and the sensor 120, further reducing the possibility of the supporting member 51 directly contacting the sensor 120 and causing the supporting member 51 to scratch the outer surface of the sensor 120 protruding from the shell 110.

[0185] In some embodiments, the driver 40 includes a motor. The wiping assembly 50 is connected to the output shaft of the motor. The motor drives the wiping assembly 50 to rotate around the axis of the output shaft through the output shaft, so that the wiping portion 50a performs a wiping and cleaning action. The rotation axis S of the wiping assembly 50 can coincide with the axis of the output shaft of the motor.

[0186] In the embodiment of the present application, Fig.15 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.15 As shown, the cleaning device 30 further includes a medium supply unit. The medium supply unit is disposed on the base station body 20. The medium supply unit is used to perform at least two actions of spraying the target to be cleaned, wetting the wiping unit 50a, drying the target to be cleaned, and drying the wiping unit 50a. The medium supply unit has a medium outlet. The medium outlet is oriented toward at least one of the wiping unit 50a and the lawn mower parking position 20a.

[0187] In some achievable embodiments, the medium supply unit includes a medium introduction pipe 300. The medium introduction pipe 300 is used to introduce liquid medium and / or gaseous medium to perform at least two actions of spraying the target to be cleaned, wetting the wiping portion 50a, drying the target to be cleaned, and drying the wiping portion 50a. Liquid medium and / or gaseous medium can be introduced through one medium introduction pipe 300, which is conducive to reducing the number of medium introduction pipes 300 to be set, and is conducive to reducing the difficulty of installing the medium introduction pipe 300 on the base station body.

[0188] In some practicable embodiments, the medium outlet of the medium supply unit is directed toward the wiping unit 50a and the target to be cleaned. The target to be cleaned may be the sensor 120 of the lawn mower 100. The medium supply unit may spray liquid to the sensor 120 to humidify the sensor 120. Then, the driver 40 is started, and the driver 40 drives the wiping unit 50a to wipe and clean the outer surface of the sensor 120 protruding from the housing 110 in a wet state, thereby improving the cleaning efficiency and cleaning effect.

[0189] The medium supply unit can supply liquid to the wiping portion 50a to wet the wiping portion 50a, so that the wiping portion 50a is in a wet state. After the wiping portion 50a is humidified, the driver 40 is started. The driver 40 drives the wiping portion 50a in a wet state to wipe and clean the outer surface of the sensor 120 protruding from the housing 110, thereby improving the cleaning efficiency and cleaning effect.

[0190] The medium supply unit can deliver liquid of a certain pressure, i.e., high-pressure liquid, to the sensor 120, and the high-pressure liquid can be used to wash away the dirt on the surface of the sensor 120 that is difficult to clean. Then, the driver 40 is started, and the driver 40 drives the wiping unit 50a to wipe and clean the outer surface of the sensor 120 protruding from the housing 110 in a wet state, thereby improving the cleaning efficiency and cleaning effect.

[0191] After the wiping assembly 50 finishes cleaning the sensor 120, the lawn mower 100 drives away from the lawn mower base station 10. The medium supply unit can supply an appropriate amount of liquid to the wiping portion 50a to rinse and clean the wiping portion 50a, thereby removing dirt on the wiping portion 50a, so that the wiping portion 50a itself maintains good cleanliness.

[0192] In some achievable embodiments, the medium outlet of the medium supply unit is directed toward the wiping unit 50a and the target to be cleaned. The target to be cleaned may be the sensor 120 of the lawn mower 100. The medium supply unit may blow hot air toward the wiping unit 50a and the outer surface of the sensor 120 protruding from the housing 110. In the case where dirt such as oil is adhered to the outer surface of the sensor 120 protruding from the housing 110, the hot air blown by the medium supply unit may heat the dirt such as oil on the outer surface of the sensor 120 protruding from the housing 110 to improve the fluidity of the dirt such as oil, thereby reducing the difficulty of the wiping member 52 in wiping off dirt such as oil, and improving the cleaning efficiency and cleaning effect.

[0193] After the wiping assembly 50 finishes cleaning the sensor 120, the medium supply unit can blow hot air to the wiping portion 50a to heat the wiping portion 50a, thereby drying the wiping portion 50a and keeping the wiping portion 50a dry, which is beneficial to reduce the possibility of the wiping portion 50a becoming moldy or producing odor due to the wiping portion 50a being in a wet state.

[0194] After the wiping assembly 50 finishes cleaning the sensor 120 , the medium supply unit may blow hot air toward the sensor 120 to dry the outer surface of the sensor 120 , thereby preventing residual liquid on the outer surface of the sensor 120 from affecting the normal operation of the sensor 120 .

[0195] In some embodiments, see Fig.15 As shown, the medium supply unit further includes a water supply mechanism 60, an air supply mechanism 80 and a conversion valve 90. The medium introduction pipeline 300 is connected to the conversion valve 90. The conversion valve 90 is connected to the water supply mechanism 60. The conversion valve 90 is connected to the air supply mechanism 80. The conversion valve 90 is used to control the connection or isolation between the medium introduction pipeline 300 and the water supply mechanism 60 or the medium introduction pipeline 300 and the air supply mechanism 80.

[0196] Exemplarily, the water supply mechanism 60 may be disposed in the base station body 20. The air supply mechanism 80 may be disposed in the base station body 20. The conversion valve 90 may be a solenoid valve or a hydraulic valve.

[0197] When the switching valve 90 controls the medium introduction pipeline 300 to communicate with the water source supply mechanism 60, the medium introduction pipeline 300 is isolated from the air source supply mechanism 80. The water source supply mechanism 60 can supply an appropriate amount of water to the wiping portion 50a and / or the sensor 120 through the medium introduction pipeline 300 to wet the wiping portion 50a and / or the sensor 120.

[0198] By setting the conversion valve 90, the medium supply unit can switch between the four actions of spraying the target to be cleaned, wetting the wiping part 50a, drying the target to be cleaned, and drying the wiping part 50a. After the wiping component 50 completes the cleaning of the sensor 120, the lawn mower 100 drives away from the lawn mower base station 10. The water source supply mechanism 60 can supply an appropriate amount of water to the wiping part 50a through the medium introduction pipe 300 to rinse and clean the wiping part 50a, thereby removing the dirt on the wiping part 50a, so that the wiping part 50a itself maintains a good cleanliness. Exemplarily, the flushing and cleaning time of the wiping part 50a by the water source supply mechanism 60 can be 30 seconds to 90 seconds. When the wiping part 50a is rinsed and cleaned, the lawn mower 100 has already driven away from the lawn mower base station 10, so in the process of rinsing and cleaning the wiping part 50a, the dirt dropped from the wiping part 50a will not cause secondary pollution to the lawn mower 100.

[0199] In some embodiments, see Fig.15 As shown, the water source supply mechanism 60 includes a liquid storage tank 61, a booster pump 62 and a liquid supply pipeline 63. The liquid storage tank 61 is connected to the booster pump 62. The booster pump 62 is connected to the liquid supply pipeline 63. The liquid storage tank 61 is used to store liquid to be used, for example, the liquid can be water or the liquid can include water and detergent. The booster pump 62 can extract liquid from the liquid storage tank 61 and pump the liquid to the liquid supply pipeline 63. The liquid supply pipeline 63 is connected to the conversion valve 90. The high-pressure liquid pressurized by the booster pump 62 can pass through the liquid supply pipeline 63, the conversion valve 90 and the medium introduction pipeline 300, and finally be discharged from the medium outlet of the medium introduction pipeline 300.

[0200] In some examples, the water supply mechanism 60 is disposed inside the base station body 20. The liquid storage tank 61 and the booster pump 62 are both disposed inside the base station body 20. The liquid supply pipeline 63 can be disposed inside the base station body 20. The base station body 20 can provide protection for the liquid storage tank 61, the booster pump 62, and the liquid supply pipeline 63. At the same time, the arrangement of the liquid storage tank 61, the booster pump 62, and the liquid supply pipeline 63 will not affect the appearance of the base station body 20.

[0201] In some embodiments, Fig.16 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.16 As shown, the lawn mower base station 10 further includes a detection sensor 70. The detection sensor 70 is disposed on the base station body 20. The detection sensor 70 is disposed corresponding to the lawn mower parking position 20a. The detection sensor 70 is in communication connection with the cleaning device 30. The detection sensor 70 is used to detect the arrival or departure of the lawn mower 100. When the detection sensor 70 detects that the lawn mower 100 has docked at the station, the lawn mower base station 10 can control the cleaning device 30 to start, so as to wipe and clean the outer surface of the sensor 120 protruding from the housing 110.

[0202] In some examples, the detection sensor 70 may be disposed on the side support portion 21 of the base station body 20 .

[0203] In some examples, the medium supply unit further includes a water supply mechanism 60. When the detection sensor 70 detects that the lawn mower 100 has docked at the station, the lawn mower base station 10 can control the water supply mechanism 60 to humidify the wiping portion 50a and / or the sensor 120. After the detection sensor 70 detects that the lawn mower 100 has exited the station from the base station body 20, the lawn mower base station 10 can control the water supply mechanism 60 to rinse and clean the wiping portion 50a.

[0204] In some examples, the detection sensor 70 includes at least one of a touch switch, a photoelectric sensor, and a Hall sensor.

[0205] The touch switch may be a physical switch. When the lawn mower 100 stops at a station, the lawn mower 100 may press the touch switch to turn on the touch switch. After the lawn mower 100 leaves the station, the lawn mower 100 may release the touch switch to turn off the touch switch.

[0206] The photoelectric sensor may be an infrared sensor. The photoelectric sensor may determine whether the lawn mower 100 has docked at a station or left the station from the base station body 20 by sensing the distance of the lawn mower 100 .

[0207] A magnet may be provided on the lawn mower 100. The Hall sensor may determine whether the lawn mower 100 has docked at the station or exited the base station body 20 by sensing the change in the magnetic field strength of the magnet on the lawn mower 100. When the lawn mower 100 approaches the Hall sensor, the Hall sensor detects that the magnetic field strength of the magnet of the lawn mower 100 gradually increases. When the lawn mower 100 docks at the station, the Hall sensor detects that the magnetic field strength of the magnet of the lawn mower 100 no longer changes. When the lawn mower 100 exits the station, the lawn mower 100 moves away from the Hall sensor. The Hall sensor detects that the magnetic field strength of the magnet of the lawn mower 100 gradually decreases.

[0208] In some embodiments, when the switching valve 90 controls the medium introduction pipeline 300 to communicate with the air source supply mechanism 80, the medium introduction pipeline 300 is isolated from the water source supply mechanism 60. The air source supply mechanism 80 can supply hot air to the wiping portion 50a and / or the sensor 120 through the medium introduction pipeline 300 to dry the wiping portion 50a and / or the sensor 120.

[0209] In some embodiments, see Fig.15As shown, the air source supply mechanism 80 includes a heater 81, a fan 82, a connecting pipe 83 and a ventilation duct 84. The fan 82 is arranged in the ventilation duct 84. The fan 82 and the heater 81 are connected by the connecting pipe 83. The ventilation duct 84 is connected to the connecting pipe 83. The ventilation duct 84 is connected to the conversion valve 90. The fan 82 is used to convey the hot air generated by the heater 81 to the ventilation duct 84. The fan 82 can pressurize the gas so that the gas flowing through the fan 82 is a gas with a higher pressure. The heater 81 can heat the gas. The fan 82 can convey the heated gas to the ventilation duct 84. The ventilation duct 84 is connected to the conversion valve 90. The gas can pass through the fan 82, the ventilation duct 84 and the medium introduction duct 300, and finally be discharged from the medium outlet of the medium introduction duct 300.

[0210] In some embodiments, the air supply mechanism 80 is disposed inside the base station body 20. The fan 82 and the heater 81 are both disposed inside the base station body 20. The base station body 20 can provide protection for the fan 82, the heater 81, and the ventilation duct 84. At the same time, the arrangement of the fan 82, the heater 81, and the ventilation duct 84 will not affect the appearance of the base station body 20.

[0211] In some examples, the heater 81 may include at least one of a ceramic heating element, a resistance heating wire, an electric heating tube, and an electric heating film.

[0212] In some achievable ways, Fig.17 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.17 As shown, the medium supply unit includes a water supply mechanism 60. The medium supply unit is used to perform two actions of spraying the sensor 120 and wetting the wiping unit 50a. The water supply mechanism 60 may include a liquid supply pipeline 63. The liquid supply pipeline 63 is connected to the medium introduction pipeline 300.

[0213] In some achievable ways, Fig.18 The partial structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.18 As shown, the medium supply unit includes an air supply mechanism 80. The medium supply unit is used to perform two actions of drying the sensor 120 and drying the wiping unit 50a. The air supply mechanism 80 may include a ventilation duct 84. The ventilation duct 84 is connected to the medium introduction duct 300.

[0214] In some embodiments, Fig.19 The partial cross-sectional structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.19As shown, the support member 51 includes a connected inner cavity 51a and a channel hole 51b. The channel hole 51b is connected to the accommodating space 50b. The medium introduction pipeline 300 is connected to the inner cavity 51a through a switching mechanism. The wiper 52 is provided with a flow channel hole 52a that penetrates. At least a part of the channel holes 51b are connected to the corresponding flow channel holes 52a. The connected channel holes 51b and the flow channel holes 52a can simultaneously supply liquid and / or gas to flow through the channel holes 51b and the flow channel holes 52a, and can be discharged from the flow channel holes 52a, so that the medium supply part can perform at least two actions of wetting the wiper 52, drying the wiper 52, spraying sensor 120, and drying sensor 120.

[0215] In some embodiments, the switching mechanism includes a sleeve 85. The sleeve 85 has a cavity 851. The medium introduction pipe 300 is connected to the sleeve 85. The medium introduction pipe 300 is connected to the cavity 851. The wiping assembly 50 also includes a switching shaft 53. The switching shaft 53 is connected to the support member 51. The switching shaft 53 is connected to the driver 40. The support member 51 includes a connected inner cavity 51a and a channel hole 51b. The channel hole 51b is connected to the accommodating space 50b. The switching shaft 53 includes a medium conveying channel 53a. The switching shaft 53 is penetrated by the sleeve 85. The medium conveying channel 53a is connected to the cavity 851 of the sleeve 85. When the driver 40 drives the switching shaft 53 to rotate, the switching shaft 53 rotates relative to the sleeve 85, and the sleeve 85 is in a stationary state. Exemplarily, the sleeve 85 can be connected to the base station body 20.

[0216] In some examples, the medium introduction pipe 300 is sealed and connected to the sleeve 85, which is conducive to avoiding the problem of liquid leakage or gas leakage between the medium introduction pipe 300 and the sleeve 85. The adapter shaft 53 is sealed and connected to the sleeve 85, which is conducive to avoiding the problem of liquid leakage or gas leakage between the adapter shaft 53 and the sleeve 85. The adapter shaft 53 is sealed and connected to the support member 51, which is conducive to avoiding the problem of liquid leakage or gas leakage between the adapter shaft 53 and the support member 51.

[0217] For some examples, see Fig.19 As shown, the number of channel holes 51b can be equal to the number of flow channel holes 52a. For example, 100 channel holes 51b can be provided on the support member 51. 100 flow channel holes 52a can be provided on the wiper 52. The 100 channel holes 51b on the support member 51 are correspondingly connected to the 100 flow channel holes 52a on the wiper 52.

[0218] In some examples, Fig. 20 The partial cross-sectional structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig. 20As shown, the number of channel holes 51 b may be greater than the number of flow channel holes 52 a. A portion of the channel holes 51 b are connected to the corresponding flow channel holes 52 a, and another portion of the channel holes 51 b are blocked and covered by the wiper 52.

[0219] The connected channel hole 51b and the flow channel hole 52a can simultaneously allow liquid and / or gas to flow through the channel hole 51b and the flow channel hole 52a, and be discharged from the flow channel hole 52a into the accommodation space 50b. For example, the liquid discharged from the flow channel hole 52a can spray the sensor 120. At the same time, the liquid or gas can be directly transported to the wiping member 52 through the channel hole 51b blocked and covered by the wiping member 52 to wet the wiping member 52 or dry the wiping member 52. Therefore, the cleaning device 30 can simultaneously realize the function of spraying the sensor 120 and the function of wetting the wiping member 52.

[0220] Exemplarily, each flow channel hole 52a is connected to the channel hole 51b. For example, each flow channel hole 52a can be used to realize the function of spraying or drying the sensor 120. For example, 100 channel holes 51b can be provided on the support member 51. 50 flow channel holes 52a can be provided on the wiper 52. The 50 channel holes 51b on the support member 51 are correspondingly connected to the 50 flow channel holes 52a on the wiper 52. The remaining 50 channel holes 51b on the support member 51 are blocked and covered by the wiper 52.

[0221] For example, see Fig. 20 As shown, the diameter of the flow channel hole 52a is equal to the diameter of the channel hole 51b. When the wiper 52 is arranged on the support member 51, the axis of the flow channel hole 52a can coincide with the axis of the channel hole 51b. The area where the flow channel hole 52a is formed on the wiper 52 is closer to the outlet of the channel hole 51b. The liquid and / or gas discharged from the channel hole 51b can be transported to the wiper 52 more quickly to humidify or dry the wiper 52.

[0222] Exemplarily, in such a manner that the diameter of the flow channel hole 52 a is equal to the diameter of the channel hole 51 b , the cleaning device 30 can realize the function of the spray sensor 120 and the function of the wet wiper 52 .

[0223] In some examples, Fig.21 The partial cross-sectional structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.21 As shown, the number of channel holes 51b can be less than the number of flow channel holes 52a. For example, 50 channel holes 51b can be provided on the support member 51. 100 flow channel holes 52a can be provided on the wiper 52. The 50 channel holes 51b on the support member 51 are correspondingly connected to the 50 flow channel holes 52a on the wiper 52. The remaining 50 flow channel holes 52a on the wiper 52 are blocked and covered by the support member 51.

[0224] The connected channel holes 51b and flow holes 52a can simultaneously allow liquid and / or gas to flow through the channel holes 51b and the flow holes 52a, and be discharged from the flow holes 52a into the accommodating space 50b. After the wiper 52 absorbs the liquid, the liquid can flow to the flow holes 52a covered by the support member 51 and flow out from the corresponding flow holes 52a to humidify the wiper 52 and / or the sensor 120. When drying the wiper 52, water vapor can be quickly dissipated from the flow holes 52a covered by the support member 51, which is conducive to improving the drying efficiency.

[0225] For example, see Fig.21 As shown, the diameter of the flow channel hole 52a is larger than the diameter of the channel hole 51b. The entire area of ​​each channel hole 51b is connected to the flow channel hole 52a. When the wiper 52 is set on the support member 51, the axis of the flow channel hole 52a can coincide with the axis of the channel hole 51b, or it can not coincide with the axis of the channel hole 51b. In the case where the axis of the flow channel hole 52a does not coincide with the axis of the channel hole 51b, since the diameter of the flow channel hole 52a is larger than the diameter of the channel hole 51b, it is still possible to make it difficult for the wiper 52 to block the channel hole 51b, so as to ensure that the transition between the channel hole 51b and the flow channel hole 52a is smooth. In addition, the liquid and / or gas discharged from the channel hole 51b can flow smoothly through the flow channel hole 52a, and is not easily blocked by the wiper 52, which is conducive to reducing the flow resistance of the liquid and / or gas.

[0226] Exemplarily, in a manner where the diameter of the flow channel hole 52a is greater than the diameter of the channel hole 51b, the cleaning device 30 can perform the functions of the spray sensor 120 and the drying sensor 120. The liquid discharged from the channel hole 51b may not wet the wiper 52.

[0227] In some examples, Fig. 22 The partial cross-sectional structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig. 22 As shown, the number of channel holes 51b may be equal to the number of flow channel holes 52a. The diameter of the flow channel hole 52a is greater than the diameter of the channel hole 51b.

[0228] In some examples, Fig.23 The partial cross-sectional structure of the lawn mower base station 10 according to an embodiment of the present application is schematically shown. Fig.23 As shown, the diameter of the flow channel hole 52a is smaller than the diameter of the channel hole 51b. The wiping member 52 blocks the channel hole 51b.
