The embodiment of the utility model provides a walking device 1000, the walking device 1000 includes a fuselage 200, a mounting body 10 and a control assembly 20, and the mounting body 10 is mounted on the fuselage 200. The control assembly 20 is mounted on the mounting body 10. The control assembly 20 includes at least two of a height adjustment member 21, a function control member 22 and a visual member 23. In this embodiment, by setting at least two of the height adjustment member 21, the function control member 22 and the visual member 23 on the mounting body 10, the integration of the walking device 1000 is greatly improved through a modular design, the structural complexity of the walking device 1000 is reduced, and the installation and maintenance difficulty of the walking device 1000 is reduced. Exemplarily, in this embodiment, the height adjustment member 21, the function control member 22 and the visual member 23 are all mounted on the mounting body 10, which further improves the integration of each control component in the walking device 1000.

[0025] Among them, the walking device 1000 can be a mowing device, a four-wheel walking device, a pesticide spraying device, a crop harvesting device, a sweeping device, etc. Exemplarily, the walking device 1000 can be configured as a mowing device, and the walking device 1000 also includes a knife disc arranged on the fuselage 200, and the knife disc is used to trim the lawn. Among them, the height adjustment member 21 is used to adjust the lifting height of the knife disc of the walking device 1000. The function control member 22 is used to control the working state of the walking device 1000, for example, to control the walking device 1000 to be in a mowing state, a driving state, a stop state, etc. The visual member 23 is used to obtain the picture information on the traveling direction of the walking device 1000. The controller of the walking device 1000 judges the current road condition according to the picture information obtained by the visual member 23, so as to regulate the traveling direction and working state of the walking device 1000. In some embodiments, the walking device 1000 can also be configured as a sweeping device, and the height adjustment member 21 can be used to adjust the height of the cleaning brush.

[0026] For a clearer description, in the present utility model, the X-axis direction is defined as the width direction of the walking device 1000, the Y-axis direction is defined as the front-to-back direction of the walking device 1000, and the Z-axis direction is defined as the height direction of the walking device 1000. The length direction, width direction, and height direction of the walking device 1000 are perpendicular to each other. Among them, the positive direction of the Y-axis is the front end direction of the walking device 1000, and the reverse direction of the Y-axis is the rear end direction of the walking device 1000. The traveling direction of the walking device 1000 is parallel to the Y-axis direction. When the walking device 1000 is working, traveling along the positive direction of the Y-axis is forward, and traveling along the reverse direction of the Y-axis is backward. For the convenience of description, the up and down, left and right, front and back directions in the present utility model are relative positions and do not constitute a limitation to the implementation. The front and back directions, width directions, and height directions of the walking device 1000 can be customized according to the specific structure of the product and the perspective of the drawings, and the present utility model does not make specific limitations.

[0027] Along the front-to-back direction Y of the walking device 1000, the function control component 22 is located between the height adjustment component 21 and the visual component 23. The visual component 23 is installed at the end of the installation body 10 close to the front end of the walking device 1000, so that the visual component 23 can better obtain the picture information in the moving direction of the walking device 1000. Among them, the height adjustment component 21 is usually not adjusted after the adjustment is completed, and the frequency of use of the height adjustment component 21 is low. The user's frequency of use of the function control component 22 is higher than the frequency of use of the height adjustment component 21. In this embodiment, by setting the function control component 22 at a position close to the front end of the height adjustment component 21 near the fuselage 200, the user's convenience in controlling the walking device 1000 can be improved, thereby enhancing the user experience.

[0028] The height adjustment member 21, the function control member 22 and the visual member 23 may be arranged along the front-rear direction Y of the walking device 1000. In some embodiments, the height adjustment member 21, the function control member 22 and the visual member 23 may also be arranged in other ways, such as in a triangular arrangement, along the width direction X of the walking device 1000, etc.

[0029] At least one of the height adjustment member 21, the function control member 22, and the visual member 23 is detachably connected to the installation body 10. For example, in this embodiment, the height adjustment member 21, the function control member 22, and the visual member 23 are detachably connected to the installation body 10, respectively. When one or more of the height adjustment member 21, the function control member 22, and the visual member 23 fails, the height adjustment member 21, the function control member 22, and the visual member 23 can be individually disassembled and assembled, thereby reducing the difficulty of installation and maintenance of the walking device 1000.

[0030] The installation body 10 is detachably connected to the fuselage 200. Compared with the existing walking device, the installation body 10 in this embodiment is detachably arranged relative to the fuselage 200. When one or more of the height adjustment member 21, the function control member 22 and the visual member 23 are damaged, the installation body 10 can be disassembled from the fuselage 200 as a whole, thereby facilitating the inspection and repair of the control assembly 20 on the installation body 10, and reducing the maintenance difficulty of the walking device 1000.

[0031] The mounting body 10 includes a mounting plate 11, a connecting plate 12 and a fixing plate 13. The connecting plate 12 is connected to the peripheral side of the mounting plate 11. The fixing plate 13 is connected to one end of the connecting plate 12 away from the mounting plate 11. The fixing plate 13 is used to connect with the fuselage 200. The height adjustment member 21 and the function control member 22 are respectively mounted on the mounting plate 11. The visual member 23 is located on the side of the connecting plate 12 close to the front end of the fuselage 200. The mounting plate 11 is extended along the front-to-back direction Y of the walking device 1000. The mounting plate 11 is arranged higher than the fuselage 200 in the height direction Z of the walking device 1000 to facilitate the user to operate the height adjustment member 21 and the function control member 22 on the mounting plate 11.

[0032] The connecting plate 12 is arranged around the mounting plate 11. One end of the connecting plate 12 away from the fuselage 200 protrudes from the fuselage 200, and the mounting plate 11 is connected to the end of the connecting plate 12 away from the fuselage 200. Among them, a mounting opening is provided on the fuselage 200, and the connecting plate 12 is inserted into the mounting opening. The mounting plate 11 and the connecting plate 12 are enclosed to form a accommodating space, and the part of the functional control part 22 located in the fuselage 200 can be at least partially accommodated in the accommodating space. In this embodiment, the connecting plate 12 is protruded relative to the fuselage 200, so that the heat generated by the functional control part 22 during operation can be promptly dissipated to the outside of the walking device 1000 through the part of the connecting plate 12 located outside the fuselage 200, thereby improving the heat dissipation capacity.

[0033] The connecting plate 12 includes a first connecting plate 121 and a second connecting plate 122 connected to the first connecting plate 121. The first connecting plate 121 is connected to both sides of the mounting plate 11 along the width direction X of the walking device 1000. The second connecting plate 122 is connected to a side of the mounting plate 11 close to the front end of the walking device 1000. Exemplarily, the first connecting plate 121 is extended along the height direction Z of the walking device 1000. The second connecting plate 122 is tilted relative to the mounting plate 11 toward the front end of the walking device 1000. The second connecting plate 122 is at an obtuse angle to the mounting plate 11. The visual member 23 is adjacent to the second connecting plate 122. The visual member 23 is arranged at an angle with the height direction of the walking device 1000 on one side of the second connecting plate 122 and cooperates with the second connecting plate 122. A rear cover is provided on the side of the visual member 23 facing the second connecting plate 122, and the rear cover and the housing of the visual member 23 are enclosed to form a receiving space for receiving a camera. The second connecting plate 122 is tilted toward the front end of the walking device 1000, so that when moisture enters the position between the visual component 23 and the second connecting plate 122, the moisture can flow away quickly and be located on the side of the rear cover of the visual component 23 facing the ground, thereby preventing the moisture from flowing upward into the receiving space of the visual component 23, thereby improving the waterproof ability of the visual component 23.

[0034] The fixing plate 13 is extended along the front-rear direction Y and the width direction X of the walking device 1000. The fixing plate 13 is arranged around the connecting plate 12. After the installation body 10 is installed on the fuselage 200, the fixing plate 13 is located inside the fuselage 200. In some embodiments, the fixing plate 13 can also be arranged outside the fuselage 200.

[0035] The mounting plate 11 is bent or tilted toward the ground, and / or the fixing plate 13 is bent or tilted toward the ground. In this embodiment, the side of the fuselage 200 away from the ground is bent or tilted toward the ground. The mounting plate 11 is bent or tilted toward the ground, which is conducive to the moisture and debris from the mounting plate 11 to slide off when the external moisture and debris fall onto the mounting plate 11, and avoids the moisture and debris from accumulating on the mounting plate 11. Among them, along the front and rear direction of the walking device 1000, the height of the mounting plate 11 from the ground on the side close to the front end of the walking device 1000 is less than the height of the mounting plate 11 from the ground on the side close to the rear end of the walking device 1000. In some embodiments, the surface of the side of the mounting plate 11 facing away from the ground can be constructed as a plane, and the mounting plate 11 is tilted toward the ground. In some embodiments, the surface of the side of the mounting plate 11 facing away from the ground can be constructed as a curved surface. For example, the mounting plate 11 is bent toward the ground. In some embodiments, the mounting plate 11 can also be set horizontally relative to the ground.

[0036] In this embodiment, the fixing plate 13 cooperates with the side of the fuselage 200 away from the ground. The fixing plate 13 is bent or tilted in the direction toward the ground so that moisture can flow away quickly under the guiding effect of the fixing plate 13, avoiding moisture accumulation at the connection between the fixing plate 13 and the fuselage 200, and reducing the air resistance of the walking device 1000 when traveling. Among them, the surface of the side of the fuselage 200 away from the ground is arranged in an arc shape and bent in the direction of the ground. The side of the fixing plate 13 facing the ground is bent in the direction of the ground. In some embodiments, the surface of the side of the fuselage 200 away from the ground can be arranged in a plane and tilted in the direction of the ground. The side of the fixing plate 13 facing the ground is tilted in the direction of the ground. In some embodiments, the fixing plate 13 can also be arranged horizontally relative to the ground.

[0037] In some embodiments, the installation body 10 further includes an extension plate 14. The extension plate 14 is connected to one end of the fixing plate 13 away from the connecting plate 12. The extension plate 14 is extended from the fixing plate 13 in a direction away from the installation plate 11. A sinking groove is provided at a position of the fixing plate 13 near the extension plate 14, and a fixing groove for matching with a fixing structure on the fuselage 200 is provided in the sinking groove. In some embodiments, a fixing protrusion for matching with a fixing structure on the fuselage 200 may also be provided in the sinking groove. The installation body 10 and the fuselage 200 may be fixedly connected together by fasteners such as screws.

[0038] In this embodiment, the visual component 23 includes a front camera 231 and a rear camera 232. The front camera 231 is located on the side of the visual component 23 close to the front end of the fuselage 200, and the rear camera 232 is located on the side of the visual component 23 away from the ground. The front camera 231 is set toward the front end of the walking device 1000, and is used to obtain the picture information located in front of the walking device 1000. The rear camera 232 is set toward the oblique rear of the walking device 1000, and is used to obtain the picture information located obliquely behind the walking device 1000. Among them, when a thief steals the walking device 1000, the rear camera 232 can image the thief and provide the user with the appearance information of the thief, so that the user can recover the walking device 1000 in time, thereby improving the anti-theft ability of the walking device 1000.

[0039] In some embodiments, two front cameras 231 are provided, and the walking device 1000 can obtain distance information of obstacles located in front of the walking device 1000 through the imaging of the two front cameras 231, so as to better regulate the working state and travel route of the walking device 1000. In some embodiments, the visual component 23 may not include the rear camera 232 to reduce the manufacturing cost of the walking device 1000.

[0040] In some embodiments, the visual component 23 further includes a shielding member 233. The shielding member 233 is arranged on the side of the housing of the visual component 23 away from the ground along the height direction Z of the walking device 1000. The shielding member 233 is used to shield the sunlight, thereby reducing the internal temperature increase of the visual component 23 caused by the sunlight irradiating the housing of the visual component 23, slowing down the aging problem of the housing of the visual component 23 due to the sunlight irradiation, improving the service life of the visual component 23, and protecting the housing of the visual component 23 to prevent external debris from directly falling on the housing, causing damage to the housing. In some embodiments, the visual component 23 further includes a visual fixing portion 234 arranged on the side of the housing along the width direction X of the walking device 1000. The visual fixing portion 234 is used to be fixedly connected to the fixing plate 13. The visual fixing portion 234 is extended along the width direction X of the walking device 1000 to increase the contact area between the housing of the visual component 23 and the fixing plate 13, thereby improving the connection stability of the visual component 23 and the fixing plate 13.

[0041] The height adjustment member 21 includes a rotating portion 211, a pointer portion 212 and an indicating portion 213. The pointer portion 212 is arranged on the rotating portion 211. The indicating portion 213 is arranged on the mounting plate 11. The indicating portion 213 includes a plurality of height gears arranged around the rotating portion 211. The pointer portion 212 is used to indicate the height gear corresponding to the rotating portion 211. Among them, different height gears are used to indicate different lifting heights of the cutter disc of the walking device 1000. In some embodiments, an anti-slip structure is arranged on the rotating portion 211 to increase the friction between the user's hand and the rotating portion 211, so that the user can better rotate the rotating portion 211. Among them, the anti-slip structure can be constructed as an anti-slip groove opened on the rotating portion 211, or an anti-slip protrusion convexly arranged on the rotating portion 211.

[0042] In some embodiments, the function control element 22 includes an emergency stop element 221, which is used to control the walking device 1000 to stop the current working task and be in a stopped state. For example, when an emergency occurs in the walking device 1000, the user can press the emergency stop element 221 to immediately stop the walking device 1000 from working.

[0043] In some embodiments, the function control member 22 also includes a starter 222, which is used to turn on the walking device 1000. Among them, the starter 222 can be configured as a start key of the walking device 1000. The starter 222 is pluggable relative to the installation body 10. When the walking device 1000 does not detect the insertion of the starter 222, the walking device 1000 is in a stopped state, and at this time, the walking device 1000 cannot work. For example, when the walking device 1000 is not used for a long time, the user can take out the starter 222 to avoid the walking device 1000 from being mistakenly started, or to avoid the walking device 1000 from being stolen by a thief. After the walking device 1000 detects the insertion of the starter 222, the walking device 1000 is in a workable state, and the user can control the walking device 1000 to perform various work tasks.

[0044] Exemplarily, the emergency stop member 221 is provided with a plug-in slot for cooperating with the starter 222. After the starter 222 is inserted into the plug-in slot on the emergency stop member 221, the walking device 1000 can be in an operable state. The starter 222 and the emergency stop member 221 can share a sensor setting to reduce the manufacturing cost of the walking device 1000.

[0045] In some embodiments, the function control component 22 also includes a liquid detection component 223. The liquid detection component 223 is used to detect whether there is liquid on the mounting plate 11. For example, when it rains, the liquid detection component 223 can detect rainwater falling on the mounting plate 11. When the controller of the walking device 1000 receives a signal that the liquid detection component 223 detects moisture, it controls the walking device 1000 to return to the warehouse. Among them, the liquid detection component 223 is arranged adjacent to the visual component 23. The liquid detection component 223 is located at a position of the mounting plate 11 close to the front end of the walking device 1000, so that the moisture falling on the mounting plate 11 flows more quickly to the liquid detection component 223, thereby improving the detection effect of the liquid detection component 223. Exemplarily, the liquid detection component 223 includes a water collection tank and two sensing electrodes arranged in the water collection tank. When moisture accumulates in the water collection tank, the moisture conducts the two sensing electrodes, thereby realizing the detection of moisture. Among them, a plurality of protrusions can be arranged in the water collection tank, and the protrusions are used to destroy the surface tension of the water in the water collection tank, so that the water flowing into the water collection tank can be quickly spread out and spread on the bottom of the water collection tank, and connect the two sensing electrodes.

[0046] The function control part 22 also includes a function button 224, which is used to control the working state of the walking device 1000. The function control part 22 may include one or more of a return button, a shutdown button, a mowing button, a start button, etc. Among them, the return button is used to return the walking device 1000 to the warehouse. The shutdown button is used to turn off the walking device 1000. The mowing button is used to make the walking device 1000 perform a mowing task. The start button is used to start the current working task of the walking device 1000.

[0047] The function control part 22 also includes a signal light 225, which is used to indicate the status information of the walking device 1000. Exemplarily, the signal light 225 can be used to indicate the remaining power of the walking device 1000. Among them, the signal light 225 can be set to multiple, and the number of signal lights 225 in the lit state can indicate the remaining power of the walking device 1000. In some embodiments, the signal light 225 can also be used to indicate the signal connection status of the walking device 1000. For example, the walking device 1000 can be set to be networked, and the signal light 225 is used to indicate the signal connection strength between the walking device 1000 and the base station.

[0048] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
