[0030] The following description of various embodiments of the present invention is based on the accompanying drawings.

[0031] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" means that the components are connected to each other and their relative positional relationship remains unchanged after connection. "Rotary connection" means that the components are connected to each other and can rotate relative to each other after connection. The term "integral molding" means that during the formation of one of a plurality of components, that component is connected to the other components without requiring further processing (such as bonding, welding, snap-fit ​​connection, screw connection) to connect the two components together. The directional terms mentioned in the embodiments of this utility model, such as "top," "bottom," "inner," "outer," and "side," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. The term “and / or” as used in this invention refers to any combination of one or more of the associated listed items, as well as all possible combinations, and includes such combinations.

[0032] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a partial structure of the walking device 100 provided in this embodiment of the utility model; Figure 2 yes Figure 1 The image shows a first-view cross-sectional view of a mobile device 100. The mobile device 100 includes a housing 30, a chassis 10, a surrounding plate 40, and multiple stop members 50. The housing 30 is located above the chassis 10. The surrounding plate 40 is fixedly connected to at least one of the chassis 10 and the housing 30. The surrounding plate 40 is located between the chassis 10 and the housing 30, and together with the chassis 10 and the housing 30, forms a sealed cavity 101. The multiple stop members 50 are fixedly connected to at least one of the chassis 10 and the housing 30. The multiple stop members 50 are spaced apart around the perimeter of the surrounding plate 40 and are used to resist deformation of the surrounding plate 40.

[0033] The walking device 100 provided in this embodiment of the utility model has two advantages. First, it forms a sealed cavity 101 by enclosing the enclosure 40, the housing 30, and the chassis 10. This sealed cavity 101 can act as a barrier against substances such as water or dust, protecting the internal components of the sealed cavity 101 and improving the alignment and assembly efficiency and yield of the housing 30 and the chassis 10. Second, it has multiple stop members 50 spaced around the perimeter of the enclosure 40 to resist deformation of the enclosure 40, thereby preventing excessive deformation of the enclosure 40 and improving the sealing performance between the enclosure 40, the chassis 10, and the housing 30. This avoids the problem of the walking device 100 malfunctioning when the internal components of the sealed cavity 101 are damp or water-infiltrated, and extends the service life of the walking device 100.

[0034] The walking device 100 may include, but is not limited to, hand-held devices, riding devices, and fully automatic intelligent devices, etc., and this utility model does not limit it in this regard. The walking device 100 can move on the ground. For example, the walking device 100 can move on the ground by being pushed by a user. Or, for example, the walking device 100 has its own mobility. Specifically, the walking device 100 includes drive wheels, and the walking device 100 can move automatically on the ground through the drive wheels. The walking device 100 can be configured as, but is not limited to, cleaning equipment, lawn mowing equipment, crop harvesting equipment, etc., and this utility model embodiment does not limit it.

[0035] For example, in this embodiment, the walking device 100 further includes electrical components 20. The electrical components 20 are disposed within the sealed cavity 101, thereby preventing substances such as water or dust in the environment from affecting the performance of the electrical components 20 and extending their service life. The electrical components 20 include, but are not limited to, batteries, drive motors, circuit boards, detectors, and connection structures. It should be noted that the electrical components 20 refer to the basic components constituting the electrical system of the walking device 100. They play different roles in the circuit; for example, the electrical components 20 can realize functions such as power transmission, distribution, control, protection, and signal processing.

[0036] The walking device 100 also includes a plurality of walking wheels 110. Exemplarily, in this embodiment, the number of walking wheels 110 is set to four, namely two first wheels and two second wheels. The two first wheels are rotatably disposed at the front end of the chassis 10 in the length direction X of the walking device 100 and located on both sides of the chassis 10 in the width direction Y of the walking device 100. The two second wheels are rotatably disposed at the rear end of the chassis 10 in the length direction X of the walking device 100 and located on both sides of the chassis 10 in the width direction Y of the walking device 100.

[0037] The housing 30 is detachably mounted on the chassis 10, facilitating the maintenance, replacement, and cleaning of the internal parts of the mobile equipment 100. This allows for the separate transport of the chassis 10, housing 30, and internal parts, improving transportation and installation convenience. Exemplarily, in this embodiment, the housing 30 and chassis 10 are detachably fixedly connected by screws. Of course, in other embodiments, the housing 30 and chassis 10 may also be detachably fixedly connected by a snap-fit ​​structure or other structures; this embodiment does not impose specific limitations.

[0038] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1 For reference, the term "length direction X" can refer to the forward or backward direction of the walking device 100; or, the arrangement direction of the first and second wheels in the walking device 100, i.e., the front-back direction (where the positive X-axis is forward). The term "width direction Y" refers to the arrangement direction of the two first wheels or two second wheels in the walking device 100, i.e., the left-right direction (where the positive Y-axis is right). The term "height direction Z" refers to the direction perpendicular to the support plane of the walking device 100, i.e., the up-down direction (where the positive Z-axis is up). The length direction X, width direction Y, and height direction Z together constitute the three orthogonal directions of the walking device 100. For ease of description, the up-down, left-right, and front-back orientations in this embodiment are relative positions and do not constitute a limitation. The length direction X, width direction Y, and height direction Z of the walking device 100 can be customized according to the specific structure of the product and the perspective presented in the accompanying drawings; this invention does not impose specific limitations.

[0039] Please refer to the following: Figure 2 and Figure 3 , Figure 3 yes Figure 1A schematic diagram of the chassis 10 of the walking device 100. Exemplarily, in this embodiment, a plurality of stop members 50 are connected to the enclosure 40 to form an integral structure. Therefore, on the one hand, since the stop member 50 is fixedly connected to the housing 30 or the chassis 10, when the enclosure 40 is subjected to an inward mechanical force, the stop member 50 can prevent the enclosure 40 from deforming towards the inside of the sealed cavity 101. Furthermore, when the electrical components 20 inside the sealed cavity 101 operate, causing a large temperature difference between the inside and outside of the sealed cavity 101, and the air pressure generated inside the sealed cavity 101 causes the enclosure 40 to expand outward, the stop member 50 can also prevent the enclosure 40 from deforming towards the outside of the sealed cavity 101. This improves the sealing performance between the enclosure 40 and the chassis 10 and the housing 30, preventing the traveling equipment 100 from malfunctioning due to moisture or water ingress into the internal components of the sealed cavity 101, and extending the service life of the traveling equipment 100. On the other hand, since multiple stop members 50 are integrally formed with the enclosure 40, assembly efficiency and structural strength of the enclosure 40 are improved.

[0040] Of course, in some embodiments, multiple stop members 50 are independently arranged with the surrounding plate 40 and abut against or near the outer wall of the surrounding plate 40. Therefore, by independently arranging multiple stop members 50 with the surrounding plate 40, on the one hand, the processing difficulty is reduced, and the replacement and maintenance of the stop members 50 are facilitated; on the other hand, since the stop members 50 are abut against or near the surrounding plate 40, they can prevent the surrounding plate 40 from deforming towards the outside of the sealing cavity 101, thereby improving the sealing performance between the surrounding plate 40 and the chassis 10 and the housing 30, preventing the internal components of the sealing cavity 101 from becoming damp or infiltrated, thus extending the service life of the traveling equipment 100.

[0041] Understandably, the existing walking device 100's sealed cavity 101 lacks an additional protective structure. The operation of the electrical components 20 within the sealed cavity 101 causes a significant temperature difference between its interior and exterior, resulting in a pressure difference between the internal and external environments. Therefore, when the internal air pressure of the sealed cavity 101 reaches a preset value, it forces the enclosure 40 to expand outwards, causing deformation and opening the sealed cavity 101 to the outside air. Exemplarily, in this embodiment, multiple stoppers 50 are used to block the enclosure 40 when the air pressure in the sealed cavity 101 is greater than or equal to a preset threshold. This prevents the enclosure 40 from deforming outwards, improving the sealing performance between the enclosure 40 and the chassis 10 and housing 30. This avoids the walking device 100 malfunctioning due to moisture or water ingress into the internal components of the sealed cavity 101, extending the service life of the walking device 100. It should be noted that the preset threshold refers to the minimum air pressure inside the sealed cavity 101 that causes deformation of the enclosure 40. The preset threshold can be set based on factors such as the thickness, material, setting method, and connection method of the enclosure 40, and this embodiment of the utility model does not impose specific limitations.

[0042] Please refer to the following: Figure 2 and Figure 4 , Figure 4 yes Figure 2This is an enlarged view of the first embodiment of part I of the walking device 100. In this embodiment, the number of enclosure plates 40 is set to two. The two enclosure plates 40 are defined as a first enclosure plate 410 and a second enclosure plate 420, respectively. The first enclosure plate 410 is fixedly connected to the chassis 10. The second enclosure plate 420 is fixedly connected to the housing 30. One of the first enclosure plate 410 and the second enclosure plate 420 is provided with a snap-fit ​​groove 401, and the other of the first enclosure plate 410 and the second enclosure plate 420 is sealed and inserted into the snap-fit ​​groove 401. Therefore, on the one hand, the engaging groove 401 cooperates with the first enclosure plate 410 or the second enclosure plate 420, so that the groove wall of the engaging groove 401 can resist the enclosure plate 40 when the air pressure in the sealed cavity 101 is greater than a preset threshold, thereby improving the sealing performance between the enclosure plate 40 and the housing 30, and improving the alignment and assembly efficiency and assembly yield of the housing 30 and the chassis 10; on the other hand, based on the setting of the first enclosure plate 410 or the second enclosure plate 420 inserted into the engaging groove 401, the alignment and assembly efficiency and assembly yield of the housing 30 and the chassis 10 are improved, and the groove sidewall of the engaging groove 401 resists the first enclosure plate 410 or the second enclosure plate 420. The plate 420 forms a U-shaped wrap, so that the first enclosure plate 410 or the second enclosure plate 420 can apply pressure in multiple directions, improving the effective sealing path between the snap-fit ​​groove 401 and the first enclosure plate 410 or the second enclosure plate 420; on the other hand, the first enclosure plate 410 and the second enclosure plate 420 are respectively fixedly connected to the chassis 10 and the housing 30, which facilitates the processing and forming of the first enclosure plate 410 or the second enclosure plate 420 and the abutment groove. The insertion depth of the first enclosure plate 410 or the second enclosure plate 420 can be flexibly set, and the problem of reducing the structural strength by directly setting the snap-fit ​​groove 401 on the chassis 10 or the housing 30 is avoided.

[0043] Specifically, the second enclosure 420 is provided with a snap-fit ​​groove 401, and the first enclosure 410 is sealed and inserted into the snap-fit ​​groove 401, so that dust or water and other substances can fall out of the snap-fit ​​groove 401 under the influence of gravity, reducing the cleaning difficulty of the walking device 100. Of course, in some embodiments, the first enclosure 410 is provided with a snap-fit ​​groove 401, and the second enclosure 420 is sealed and inserted into the snap-fit ​​groove 401; this embodiment of the present invention does not impose a specific limitation.

[0044] Please refer to the following: Figure 4 and Figure 5 , Figure 5 yes Figure 2This is an enlarged view of a second embodiment of part I of the walking device 100. In the second embodiment, the first enclosure 410 includes a connecting plate 411 and a plug-in plate 412. The connecting plate 411 is connected between the plug-in plate 412 and the housing 30. The plug-in plate 412 protrudes from the end of the connecting plate 411 facing away from the housing 30 and is sealed and inserted into the snap-fit ​​groove 401. The thickness of the connecting plate 411 is greater than the thickness of the plug-in plate 412. Therefore, by setting the thickness of the connecting plate 411 to be greater than the thickness of the plug-in plate 412, the connection strength between the root of the connecting plate 411 and the housing 30 is enhanced, thereby preventing deformation of the first enclosure 410. Of course, in some embodiments, the thickness of the connecting plate 411 may also be equal to the thickness of the plug-in plate 412.

[0045] In some embodiments, the number of enclosure panels 40 is set to one, and it is fixedly connected to the housing 30. The chassis 10 is provided with a snap-fit ​​groove 401, and the enclosure panel 40 is sealed and inserted into the snap-fit ​​groove 401; or, the number of enclosure panels 40 is set to one, and it is fixedly connected to the chassis 10. The housing 30 is provided with a snap-fit ​​groove 401, and the enclosure panel 40 is sealed and inserted into the snap-fit ​​groove 401. Thus, by directly providing the snap-fit ​​groove 401 on the chassis 10 or the housing 30, material is saved and processing is convenient.

[0046] In some embodiments, the enclosure 40 is connected to the housing 30 or chassis 10 to form an integral structure, thereby enhancing the connection strength and sealing between the enclosure 40 and the housing 30 or chassis 10, and improving the assembly efficiency between the enclosure 40 and the housing 30 or chassis 10. Of course, in some embodiments, the enclosure 40 and the housing 30 or chassis 10 can also be sealed and fixedly connected by means of mounting structures, snap-fit ​​structures, etc., and the embodiments of this utility model do not make specific limitations.

[0047] In some embodiments, the walking device 100 further includes a seal 430, which is disposed within a snap-fit ​​groove 401 and sandwiched between the enclosure plate 40 and the bottom wall of the snap-fit ​​groove 401. Thus, the seal 430 improves the sealing performance between the snap-fit ​​member and the enclosure plate 40, thereby enhancing the sealing effect of the sealing cavity 101. The material of the seal 430 may include, but is not limited to, at least one of plastics, thermoplastic elastomers, and engineering plastics.

[0048] Please refer to the following: Figure 3 , Figure 4 and Figure 6 , Figure 6 yes Figure 1A schematic diagram of the structure of the housing 30 of the walking device 100 is shown. Exemplarily, in this embodiment, the plurality of stop members 50 include a plurality of first stop bodies 51 and a plurality of second stop bodies 52. The plurality of first stop bodies 51 are fixedly connected to the chassis 10. The plurality of second stop bodies 52 are fixedly connected to the housing 30. The plurality of first stop bodies 51 and the plurality of second stop bodies 52 are arranged in a one-to-one correspondence and are detachably fixedly connected. Therefore, based on the fixed connection of the first stop bodies 51 and the second stop bodies 52, the preload between the enclosure 40 and the housing 30 or chassis 10 is increased, thereby improving the sealing effect of the sealing cavity 101.

[0049] Of course, in some embodiments, the plurality of stop members 50 may also include only a plurality of first stop bodies 51 or a plurality of second stop bodies 52. For example, when the plurality of stop members 50 may also include only a plurality of first stop bodies 51, the plurality of first stop bodies 51 are directly fixedly connected to the housing 30 by a locking structure. When the plurality of stop members 50 may also include only a plurality of second stop bodies 52, the plurality of second stop bodies 52 are directly fixedly connected to the chassis 10 by a locking structure.

[0050] Specifically, in this embodiment, the stop member 50 is configured as a cylindrical structure, thereby ensuring uniform stress distribution throughout the overall structure of the stop member 50 and improving its torsional resistance. Of course, in some embodiments, the stop member 50 may also be configured as at least one of a frustum-shaped structure, a prism-shaped structure, and a combination thereof.

[0051] For example, in this embodiment, one of the first stop body 51 and the second stop body 52 is provided with a positioning groove 501, and the other of the first stop body 51 and the second stop body 52 is disposed within the positioning groove 501. Therefore, the positioning groove 501 facilitates the alignment and assembly of the first stop body 51 and the second stop body 52, preventing the housing 30 from rotating relative to the chassis 10 in the circumferential direction; and improving the stability and sealing of the connection between the housing 30 and the chassis 10. Of course, in some embodiments, the other of the first stop body 51 and the second stop body 52 may also be provided with a positioning protrusion that cooperates with and is fixed to the positioning groove 501.

[0052] For example, in this embodiment, the stop 50 and the surrounding plate 40 are located on the same side of the engaging groove 401, and the stop 50 is higher than the surrounding plate 40 in the height direction Z of the traveling device 100. Therefore, the stop 50 can limit the depth to which the surrounding plate 40 is inserted into the engaging groove 401, improving the assembly yield between the housing 30 and the chassis 10. Specifically, the first stop 51 is located on the same side as the surrounding plate 40, and the second stop 52 is located on the same side as the engaging groove 401. The first stop 51 is lower than the surrounding plate 40 in the height direction Z of the traveling device 100, and the second stop 52 is higher than the opening of the engaging groove 401 in the height direction Z of the traveling device 100.

[0053] Of course, in some embodiments, the first stop 51 is located on the same side as the surrounding plate 40, and the second stop 52 is located on the same side as the engaging groove 401. The first stop 51 is lower than the surrounding plate 40 in the height direction Z of the traveling device 100, and the second stop 52 is higher than the opening of the engaging groove 401 in the height direction Z of the traveling device 100. In other embodiments, the first stop 51 is flush with the surrounding plate 40 in the height direction Z of the traveling device 100, and the second stop 52 is flush with the opening of the engaging groove 401 in the height direction Z of the traveling device 100. The stop member 50 may also include only the first stop 51 or the second stop 52.

[0054] In this embodiment, the enclosure 40 is arranged in a closed loop and configured as an irregularly shaped plate. Thus, on the one hand, the enclosure 40 can be configured as an irregularly shaped plate according to the arrangement of the internal components of the mobile device 100, so that the enclosure 40 can flexibly wrap, support and isolate the various internal components of the mobile device 100; on the other hand, the irregularly shaped plate can provide cushioning and support for protruding parts, avoid protruding parts becoming the point of impact concentration, and prevent the mobile device 100 from being damaged due to uneven force during transportation or operation.

[0055] Of course, in some embodiments, the enclosure 40 can also be configured as a non-irregularly shaped panel. It should be noted that an irregularly shaped panel refers to the enclosure 40 having an irregular shape, while a non-irregularly shaped panel refers to the enclosure 40 having a regular shape. For example, a non-irregularly shaped panel can be, but is not limited to, a rectangular panel, a square panel, a circular panel, a triangular panel, a trapezoidal panel, and a polygonal panel. Irregularly shaped panels can include combinations of panels with different regular shapes; or combinations of panels with different irregular shapes; or combinations of panels with both regular and irregular shapes. Regularly shaped panels include, but are not limited to, combinations of regular patterns such as rectangular panels, square panels, semi-circular panels, circular panels, triangular panels, trapezoidal panels, and polygonal panels.

[0056] Exemplarily, in this embodiment, the enclosure 40 includes a plurality of first enclosure segments 41 and a plurality of second enclosure segments 42. Each second enclosure segment 42 is sealingly connected between two adjacent first enclosure segments 41. The curvature of the first enclosure segments 41 is less than the curvature of the second enclosure segments 42. A portion of a plurality of stops 50 is disposed at a position between two ends of the first enclosure segments 41 in the extending direction of the enclosure 40. The remaining portions of the plurality of stops 50 are disposed at the connection position between the first enclosure segments 41 and the second enclosure segments 42 or at the corner position of the second enclosure segments 42. Therefore, on the one hand, since the curvature of the first enclosure section 41 is less than that of the second enclosure section 42, when the pressure difference between the inside and outside of the sealed cavity 101 is greater than a preset value, the first enclosure section 41 intersecting the second enclosure section 42 is more likely to deform under the action of internal pressure. Therefore, a portion of the stop 50 is set at the position between the two ends of the first enclosure section 41 in the extension direction of the enclosure plate 40. Thus, the stop 50 can provide lateral support for the first enclosure section 41 at the position where the lateral deformation is large, reducing the risk of the first enclosure section 41 expanding and deforming relative to the chassis 10 and avoiding the problem of reduced sealing between the housing 30 and the chassis 10 due to the deformation of the first enclosure section 41. On the other hand, since the curvature of the second enclosure section 42 is greater than that of the first enclosure section 41, the structural stress of the second enclosure section 42 is relatively concentrated, which makes it easier to deform or break when subjected to external force, thereby affecting the sealing effect of the sealed cavity 101. Therefore, the first enclosure section 41 and the second enclosure section 42 are more likely to deform under the action of internal pressure. Stoppers 50 are also provided at the connection points of section 42 or at the corners of the second enclosing section 42. These stoppers 50 provide stable preload at stress concentration points on the side walls of the sealing cavity 101, and also provide lateral support for the second enclosing section 42 at locations with large lateral deformation, improving the sealing performance of the sealing cavity 101. Furthermore, since the curvature of the second enclosing section 42 is greater than that of the first enclosing section 41, during the demolding process of the stoppers 50, the second enclosing section 42... The structural precision of section 2 is lower than that of the first enclosure section 41, resulting in poor sealing between the second enclosure section 42 and the housing 30 and chassis 10. Therefore, a stop 50 is also provided at the connection position between the first enclosure section 41 and the second enclosure section 42 or at the corner position of the second enclosure section 42. The stop 50 can provide a stable pre-tightening force at the stress concentration point on the side wall of the sealing cavity 101 to press the housing 30 and chassis 10 tightly together, thereby improving the sealing performance of the sealing cavity 101.

[0057] In some embodiments, the walking device 100 further includes a plurality of reinforcing ribs 450. The plurality of reinforcing ribs 450 are fixedly connected to the surrounding plate 40 and the chassis 10 or housing 30, and are located outside the sealed cavity 101. Thus, the arrangement of the reinforcing ribs 450 provides lateral support to the surrounding plate 40, thereby improving the structural strength of the surrounding plate 40 and preventing deformation of the surrounding plate 40 from reducing the seal between the housing 30 and the chassis 10. Exemplarily, in this embodiment, a plurality of reinforcing base plates are fixed to the surrounding plate 40 and the base. The extending direction of the plurality of reinforcing ribs 450 intersects with the extending direction of the surrounding plate 40. Of course, in some embodiments, the extending direction of some reinforcing ribs 450 intersects with the extending direction of the surrounding plate 40, while the extending direction of the remaining reinforcing ribs 450 is parallel to the extending direction of the surrounding plate 40, i.e., the plurality of reinforcing ribs 450 are arranged in a crisscross pattern, thereby improving the structural strength of the reinforcing ribs 450 and the surrounding plate 40 and preventing deformation of the surrounding plate 40.

[0058] Please refer to the following: Figure 3 and Figure 7 , Figure 7 yes Figure 1 The image shows a top view of the chassis 10 of the walking device 100. In this embodiment, the enclosure 40 has a geometric center O, and the distance between the geometric center O and the enclosure 40 is defined as the center distance D. The maximum value of the center distance D is greater than or equal to 20 cm. Therefore, by setting the distance between the enclosure 40 and its geometric center O within a suitable range, the sealed cavity 101 can provide sufficient installation space for the electrical components 20, while avoiding the problem of excessively rapid temperature rise due to insufficient internal space in the sealed cavity 101, or even deformation of the enclosure 40. For example, the maximum value of the center distance D can be greater than or equal to, but is not limited to, 25 cm, 30 cm, 35 cm, 40 cm, 55 cm, or 60 cm; this embodiment of the invention does not specify a particular value.

[0059] It should be noted that the geometric center O of the enclosure 40 refers to the most central position of the enclosure 40. Specifically, the geometric center O of the enclosure 40 is the intersection of the first center line L1 of the enclosure 40 in the length direction X of the traveling device 100 and the second center line L2 of the enclosure 40 in the width direction Y of the traveling device 100. In this embodiment, the enclosure 40 is configured with a symmetrical structure, and the axis of symmetry of the enclosure 40 passes through the geometric center O of the enclosure 40.

[0060] For example, in this embodiment, the volume of the sealed cavity 101 is greater than or equal to 1000 cubic centimeters. Therefore, by setting the volume of the sealed cavity 101 to a suitable size, the sealed cavity 101 can provide sufficient installation space for the electrical components 20, while avoiding the problem of excessively rapid temperature rise due to insufficient internal space, or even deformation of the enclosure 40. For example, the volume of the sealed cavity 101 can be greater than or equal to, but not limited to, 1200 cubic centimeters, 1400 cubic centimeters, 1600 cubic centimeters, 1800 cubic centimeters, 2000 cubic centimeters, 2200 cubic centimeters, 2400 cubic centimeters, 2800 cubic centimeters, 3000 cubic centimeters, 3500 cubic centimeters, or 4000 cubic centimeters, etc., and this embodiment of the present invention does not specify a particular volume.

[0061] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, the walking device 100 further includes a stress buffer 60 and a connecting cable 70. The enclosure 40 is provided with a wiring interface 102, which communicates with the sealed cavity 101 and the external environment, and is located between two adjacent stop members 50. The stress buffer 60 is disposed within the wiring interface 102 and sealed between the connecting cable 70 and the enclosure 40. Thus, on the one hand, the electrical components 20 of the walking device 100 can be connected to the cable 70 to achieve electrical connection with an external power source or functional components, enriching the functionality of the walking device 100 and improving the overall sealing performance of the sealed cavity 101.

[0062] Please refer to the following: Figure 1 , Figure 3 and Figure 8 , Figure 8 yes Figure 1 The image shows a cross-sectional view of the walking device 100 from a second perspective. In some embodiments, the walking device 100 further includes a cutting mechanism 80 and a telescopic waterproof component 90. The chassis 10 is provided with a through hole 103. The through hole 103 communicates with the sealed cavity 101 and the external environment. The telescopic waterproof component 90 is disposed within the through hole 103 and seals between the cutting mechanism 80 and the chassis 10. Thus, the provision of the telescopic waterproof component 90 enables the cutting mechanism 80 to maintain the sealing of the sealed cavity 101 during the height adjustment process.

[0063] Specifically, the cutting mechanism 80 includes a cutting motor 81, a mounting bracket 82, and a cutting disc 83. The cutting motor 81 is mounted on the mounting bracket 82 and is connected to the cutting disc 83 via a transmission connection, thereby enabling the cutting motor 81 to drive the cutting disc 83 to rotate, thus realizing the mowing operation of the walking device 100. The mounting bracket 82 is sealed and fixedly mounted on the chassis 10, thereby achieving the sealing of the sealed cavity 101 and preventing grass clippings cut by the cutting disc 83 from entering the sealed cavity 101. One end of the telescopic waterproof component 90 is sealed to the chassis 10, and the other end of the telescopic waterproof component 90 is sealed to the mounting bracket 82, thereby preventing sewage or grass clippings from entering the sealed cavity 101 during the cleaning process of the cutting disc 83.

[0064] For example, in this embodiment, the number of cutting mechanisms 80 is set to two. Of course, in some embodiments, the number of cutting mechanisms 80 may also be set to one, three, four or more, and this embodiment of the present invention does not make a specific limitation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
