Description

Technical Field

[0001] The present application relates to the technical field of lawn mowers, and in particular to a visual component of a lawn mower and a lawn mower. Background Art

[0002] A lawn mower is a tool that automatically mows the lawn, replacing manual labor. It typically includes a vision module, which senses the operating environment, identifies obstacles, and dynamically plans and navigates the path. However, because lawn mowers operate outdoors for extended periods, water can easily seep into the vision module's cavity. This heat, generated by the operation of the mower, vaporizes the water inside the module, causing the camera to fog and affecting its proper function. Utility Model Content

[0003] The present application provides a visual component of a lawn mower and the lawn mower.

[0004] In a first aspect, the present application provides a visual component for a lawn mower, comprising a housing, a rear cover, a camera, a circuit board, and an electrolytic humidity control valve. The rear cover is configured to enclose the housing to form a receiving chamber. The housing comprises a first side panel, the first side panel and the rear cover being arranged relative to each other along a first direction, the first side panel comprising a camera hole, and the camera hole extending through the first side panel along the first direction. The camera and the circuit board are received within the receiving chamber, and the camera and the camera hole are aligned along the first direction. The electrolytic humidity control valve is fixed to the housing or the rear cover, comprises a cathode plate and an anode plate, the cathode plate and the anode plate being received within the receiving chamber, the cathode plate and the anode plate being electrically connected to the circuit board, and the electrolytic humidity control valve is configured to electrolyze water vapor within the receiving chamber.

[0005] In an embodiment of the present application, the first side panel includes a camera hole, which passes through the first side panel along a first direction, so that the field of view of the camera aligned with the camera hole is not blocked by the first side panel, allowing the camera to normally survey the working environment. The camera and the circuit board are accommodated in the accommodating chamber. During the operation of the lawn mower, the water in the visual component evaporates due to heat to form water vapor, which causes the mirror of the camera to fog, thereby hindering the normal operation of the camera. An electrolytic humidity control valve is fixed to the shell or the back cover, and the cathode and anode of the electrolytic humidity control valve are accommodated in the accommodating chamber. The cathode and anode are electrically connected to the circuit board, so that the circuit board in the visual component can provide current to the electrolytic humidity control valve, so that the electrolytic humidity control valve can work to electrolyze the water vapor in the accommodating chamber and discharge the particles formed by the electrolysis into the accommodating chamber, thereby reducing the water vapor in the accommodating chamber, thereby avoiding fogging of the camera and ensuring the normal operation of the visual component.

[0006] In one embodiment, the back cover includes a first opening, and the electrolytic humidity control valve also includes a valve shell, which is used to fix the cathode plate and the anode plate. The valve shell is passed through the first opening, and the cathode plate and the anode plate protrude from the valve shell toward the interior of the accommodating cavity.

[0007] In an embodiment of the present application, the rear cover includes a first opening, which provides an installation space for the valve housing of the electrolytic humidity control valve, so that the electrolytic humidity control valve can be installed on the rear cover.

[0008] In an embodiment of the present application, the cathode plate and the anode plate protrude from the valve shell toward the interior of the accommodating cavity, so that the anode plate and the cathode plate can be electrically connected to the circuit board in the accommodating cavity, so that the current can be transmitted to the electrolytic humidity control valve through the circuit board, so that the electrolytic humidity control valve can work, electrolyze the water vapor in the accommodating cavity and discharge it from the accommodating cavity, reduce the water vapor in the accommodating cavity, and keep the air in the accommodating cavity dry, thereby reducing the fogging of the camera and ensuring the normal operation of the visual component.

[0009] In one embodiment, the circuit board and the back cover are arranged opposite to each other along a first direction, the thickness direction of the circuit board is parallel to the first direction, and the cathode plate and the anode plate protrude from the valve housing toward the circuit board.

[0010] In an embodiment of the present application, the circuit board and the back cover are arranged relative to each other along a first direction, the thickness direction of the circuit board is parallel to the first direction, and the valve shell of the electrolytic humidity control valve is passed through the first opening of the back cover, so that the circuit board and the electrolytic humidity control valve are arranged relative to each other along the first direction, and the cathode plate and the anode plate protrude from the valve shell toward the circuit board, which facilitates the electrical connection between the cathode plate and the anode plate and the circuit board, and is conducive to shortening the electrical connection path between the electrolytic humidity control valve and the circuit board, and simplifying the cable arrangement in the visual component.

[0011] In one embodiment, the back cover also includes a first groove, the groove opening of the first groove faces away from the first side plate along the first direction, the first opening passes through the bottom of the first groove along the first direction, and the valve housing includes a mounting surface fixed to the bottom of the first groove.

[0012] In the embodiment of the present application, the notch of the first groove is oriented away from the first side plate along the first direction, thereby making the process of installing the valve housing of the electrolytic humidity control valve in the first groove of the back cover smoother. The first opening passes through the bottom of the first groove along the first direction, and the valve housing includes a mounting surface, which is fixed to the bottom of the first groove. This allows the valve housing to not only be passed through the first opening and installed in the back cover, but also to be fixed to the back cover through the first groove. This makes the valve housing of the electrolytic humidity control valve more firmly fixed, thereby making the electrical connection between the cathode and anode plates fixed by the valve housing and the circuit board more stable, which is conducive to ensuring the normal dehumidification work of the electrolytic humidity control valve, thereby keeping the accommodating cavity dry and preventing the camera from fogging.

[0013] In one embodiment, the housing includes a first protrusion, the first protrusion extending in a first direction away from the housing opening and away from the first side plate protrusion, and the first protrusion is used to secure the housing of the lawn mower. The distance between an end of the first protrusion facing away from the first side plate and the housing opening in the first direction is greater than the distance between an end of the electrolytic humidity control valve facing away from the first side plate and the housing opening.

[0014] In an embodiment of the present application, the first protrusion protrudes from the first side panel along the first direction from the opening of the shell, so that the visual component can be fixed to the housing of the lawn mower at the rear opposite to the camera along the first direction, and can enable the camera to always remain in front of the direction of movement of the lawn mower.

[0015] In an embodiment of the present application, a first protrusion is used to secure the housing of the lawn mower. Along a first direction, the distance between the end of the first protrusion facing away from the first side plate and the opening of the housing is greater than the distance between the end of the electrolytic humidity control valve facing away from the first side plate and the opening of the housing. This creates a gap between the electrolytic humidity control valve and the housing, ensuring that the discharge path of particles after electrolysis of water vapor in the accommodating chamber is not blocked. This allows the particles after electrolysis by the electrolytic humidity control valve to be smoothly discharged from the accommodating chamber into the gap between the electrolytic humidity control valve and the housing, and then out of the lawn mower. Along a first direction, the distance between the end of the first protrusion facing away from the first side plate and the opening of the housing is greater than the distance between the end of the electrolytic humidity control valve facing away from the first side plate and the opening of the housing. Furthermore, in the height direction of the lawn mower, the first protrusion shields the electrolytic humidity control valve, thereby reducing the flow of water above the lawn mower into the accommodating chamber through the installation gap between the electrolytic humidity control valve and the rear cover. This helps maintain a dry environment within the accommodating chamber, reduces fogging of the camera, and facilitates the normal operation of the visual component.

[0016] In one embodiment, the housing further comprises two second side panels, the two second side panels being arranged relative to each other along a second direction perpendicular to the first direction. One of the second side panels comprises a second opening extending through the second side panel along the second direction. The electrolytic humidity control valve further comprises a valve housing, which is used to secure the cathode and anode panels. The valve housing extends through the second opening, and the cathode and anode panels protrude from the valve housing toward the interior of the accommodating cavity. The second opening is arranged along the first direction between the circuit board and the rear cover.

[0017] In the embodiment of the present application, a second side plate includes a second opening, and the second opening passes through the second side plate along the second direction, thereby providing space for the valve housing to pass through the second side plate.

[0018] In an embodiment of the present application, the valve shell is used to fix the cathode plate and the anode plate. The valve shell is penetrated by the second opening, and the cathode plate and the anode plate protrude from the valve shell toward the interior of the accommodating cavity, so that the anode plate and the cathode plate can be electrically connected to the circuit board in the accommodating cavity, so that the current on the circuit board can be transmitted to the electrolytic humidity control valve, so that the electrolytic humidity control valve works, electrolyzes the water vapor in the accommodating cavity and discharges it out of the accommodating cavity, thereby reducing the water vapor in the accommodating cavity and keeping the air in the accommodating cavity dry, thereby reducing the fogging of the camera and ensuring the normal operation of the visual component.

[0019] In an embodiment of the present application, the second opening is arranged between the circuit board and the back cover along the first direction, so that the valve shell passing through the second opening will not interfere with the circuit board in the accommodating cavity, which is conducive to a more reasonable and regular arrangement of components in the visual assembly.

[0020] In one embodiment, a second side plate further includes a second protrusion, which protrudes from a second side plate away from the accommodating cavity along a second direction, and the length direction of the second protrusion intersects with the first direction. The shell further includes a top plate and a bottom plate, and the top plate and the bottom plate are arranged relative to each other along a third direction, and the third direction is perpendicular to the first direction and the second direction. Along the third direction, the bottom plate, the second opening, and the second protrusion are arranged in sequence.

[0021] In an embodiment of the present application, the second protrusion extends from a second side plate away from the accommodating cavity protrusion along a second direction, and the length direction of the second protrusion intersects the first direction, so that the second protrusion can be arranged at an angle on a second side plate, which is beneficial for draining water that falls from the top plate of the lawn mower and reducing water accumulation on the visual component housing. Along the third direction, the bottom plate, the second opening, and the second protrusion are arranged in sequence, so that along the third direction, the second protrusion can block the second opening. The valve housing is provided through the second opening, so that along the third direction, the second protrusion can block the electrolytic humidity control valve, thereby reducing water on the top plate of the lawn mower from flowing into the accommodating cavity through the installation gap between the electrolytic humidity control valve and a second side plate. This helps maintain a dry environment in the accommodating cavity, reduces fogging of the camera, and promotes the normal operation of the visual component.

[0022] In one embodiment, the visual component also includes an adapter, a portion of which is accommodated in the accommodating cavity, and the adapter is electrically connected to the cathode and anode plates of the electrolytic humidity control valve through a circuit board. The shell also includes a top plate and a bottom plate, and the top plate and the bottom plate are arranged relative to each other along a third direction. The bottom plate includes a third opening, and the third opening passes through the bottom plate along the third direction. The third opening is used to pass the adapter.

[0023] In an embodiment of the present application, a portion of the adapter is accommodated in the accommodating cavity, which facilitates the electrical connection between the adapter and the circuit board in the accommodating cavity. The adapter is electrically connected to the cathode and anode plates of the electrolytic humidity control valve through the circuit board, so that the current transmitted by the adapter can provide current to the anode and cathode plates of the electrolytic humidity control valve, so that the electrolytic humidity control valve performs water vapor electrolysis, thereby reducing water vapor in the accommodating cavity, maintaining a dry environment in the accommodating cavity, and reducing fogging of the camera.

[0024] In this embodiment of the present application, the base plate includes a third opening extending through the base plate in a third direction, providing space for the adapter to be inserted through the third opening. Furthermore, the base plate of the vision assembly is secured to the housing of the lawn mower, thereby shielding the adapter from exposure to the outside of the lawn mower, facilitating proper operation of the adapter. The third opening is used to insert the adapter, allowing it to electrically connect to the vision mainboard within the housing after the vision assembly is installed, thereby transmitting information collected by the camera.

[0025] In one embodiment, the electrolytic humidity control valve further includes a valve housing, a waterproof and breathable membrane, and an electrolyte membrane. The valve housing includes a central hole and a placement slot. The central hole is located in the center of the valve housing, and the placement slot is located on the side of the valve housing facing away from the accommodating cavity. The waterproof and breathable membrane is positioned within the placement slot and aligned with the central hole. The cathode plate, electrolyte membrane, and anode plate are sequentially installed within the valve housing.

[0026] In an embodiment of the present application, the valve housing includes a middle hole and a placement groove. The middle hole is opened in the middle of the valve housing. The middle hole provides a channel for the particles generated by electrolysis in the electrolytic humidity control valve to be discharged from the receiving cavity. After the cathode and anode plates are energized, the electrolyte membrane sandwiched between the cathode and anode plates can be made to work, decomposing the water vapor in the receiving cavity into hydrogen ions and oxygen. Under the action of the current of the cathode and anode plates, the hydrogen ions move to the side of the electrolyte membrane away from the receiving cavity along the first direction, so that the hydrogen ions can undergo an oxidation reaction with the external oxygen to regenerate water molecules and dissipate into the external environment, achieving a one-way irreversible dehumidification effect. The oxygen molecules in the receiving cavity can be discharged from the receiving cavity through the middle hole and the waterproof and breathable membrane arranged in the placement groove, maintaining the air pressure balance in the receiving cavity.

[0027] In a second aspect, the present application provides a lawn mower, which includes a housing and a visual component as described in the first aspect. The visual component is fixed to the housing, and a circuit board of the visual component is used to be electrically connected to a visual mainboard in the housing.

[0028] The visual component in the embodiment of the present application is provided with an electrolytic humidity control valve, which is arranged on the shell or back cover of the visual component. The cathode and anode plates of the electrolytic humidity control valve are accommodated in the accommodating cavity and electrically connected to the circuit board in the accommodating cavity, so that the circuit board can provide current to the electrolytic humidity control valve, so that the electrolytic humidity control valve can carry out electrolysis, electrolyze the water vapor in the accommodating cavity and discharge it from the accommodating cavity, thereby reducing the water vapor in the accommodating cavity, avoiding fogging of the camera, and ensuring the normal operation of the visual component.

[0041] In addition, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the structure.

[0042] An embodiment of the present application provides a visual component of a lawn mower, which includes a housing, a back cover, a camera, a circuit board, and an electrolytic humidity control valve. The back cover is used to enclose the housing to form a storage chamber, and the housing includes a first side panel, and the first side panel and the back cover are arranged relative to each other along a first direction. The first side panel includes a camera hole, and the camera hole passes through the first side panel along the first direction. The camera and the circuit board are accommodated in the storage chamber, and the camera and the camera hole are aligned along the first direction. The electrolytic humidity control valve is fixed to the housing or the back cover, and includes a cathode plate and an anode plate, which are accommodated in the storage chamber, and the cathode plate and the anode plate are electrically connected to the circuit board. The electrolytic humidity control valve is used to electrolyze water vapor in the storage chamber.

[0043] The present application arranges an electrolytic humidity control valve on the shell or back cover of the visual component. The cathode and anode plates of the electrolytic humidity control valve are accommodated in a receiving cavity and electrically connected to the circuit board in the receiving cavity, so that the circuit board can provide current to the electrolytic humidity control valve, so that the electrolytic humidity control valve carries out electrolysis, electrolyzes the water vapor in the receiving cavity and discharges it from the receiving cavity, thereby reducing the water vapor in the receiving cavity, avoiding fogging of the camera, and ensuring the normal operation of the visual component.

[0044] The visual component provided in the embodiment of the present application is applied to a lawn mower to improve the overall performance of the lawn mower.

[0045] Figure 1 It is a schematic diagram of the lawn mower 1 provided in an embodiment of the present application.

[0046] In one embodiment, the lawn mower 1 includes a visual component 10, a housing 20 and a running device 30. Figure 1 As shown, the visual component 10 is fixed to the upper portion of the housing 20 , and the visual component 10 is electrically connected to a visual mainboard (not shown) in the housing 20 .

[0047] In the embodiment of the present application, the vision component 10 receives power from the vision mainboard and transmits information collected by the vision component 10 to the vision mainboard. The walking device 30 is used to drive the lawn mower 1 to move.

[0048] If a lawn mower is operated outdoors for a long time, water will seep into the visual component. In addition, a large amount of heat will be generated during the operation of the lawn mower, causing the water in the visual component's accommodating cavity to evaporate and form water vapor. The camera is accommodated in the accommodating cavity, causing the camera's mirror to fog up, hindering the normal operation of the camera.

[0049] In this application, an electrolytic humidity control valve is installed on the shell of the visual component. By energizing the cathode and anode plates of the electrolytic humidity control valve, the electrolytic humidity control valve performs electrolysis, electrolyzes the water vapor in the accommodating cavity of the visual component into particles and discharges them out of the accommodating cavity, thereby reducing the water vapor in the accommodating cavity, avoiding fogging of the camera, and ensuring the normal operation of the visual component.

[0050] Figure 2 is a schematic diagram of the visual component 10 provided in an embodiment of the present application, Figure 3 This is an exploded view of the visual component 10 provided in an embodiment of the present application. Figure 4 This is another exploded view of the visual component 10 provided in an embodiment of the present application. Figure 5 is a schematic diagram of the housing 100 provided in an embodiment of the present application. Figure 6 It is an exploded diagram of the electrolytic humidity control valve 500 provided in an embodiment of the present application.

[0051] In one embodiment, a visual component 10 of a lawn mower 1 includes a housing 100, a rear cover 200, a camera 300, a circuit board 400, and an electrolytic humidity control valve 500. Figures 2 to 5 As shown, the back cover 200 is used to enclose the housing 100 to form a receiving cavity 600. The housing 100 includes a first side plate 110. The first side plate 110 and the back cover 200 are arranged relative to each other along the first direction Y. The first side plate 110 includes a camera hole 111. The camera hole 111 passes through the first side plate 110 along the first direction Y. The camera 300 and the circuit board 400 are accommodated in the receiving cavity 600. The camera 300 is aligned with the camera hole 111 along the first direction Y. The electrolytic humidity control valve 500 is fixed to the housing 100 or the back cover 200, as shown in FIG. Figure 6 As shown, the electrolytic humidity control valve 500 includes a cathode plate 510 and an anode plate 520, which are accommodated in a receiving cavity 600. The cathode plate 510 and the anode plate 520 are electrically connected to the circuit board 400. The electrolytic humidity control valve 500 is used to electrolyze the water vapor in the receiving cavity 600 and discharge the particles formed by electrolysis out of the receiving cavity 600.

[0052] In an embodiment of the present application, the first side panel 110 includes a camera hole 111, which passes through the first side panel 110 along the first direction Y, so that the field of view of the camera 300 aligned with the camera hole 111 is not blocked by the first side panel 110, so that the camera 300 can normally survey the working environment. The camera 300 and the circuit board 400 are accommodated in the accommodating cavity 600. During the operation of the lawn mower 1, the water in the visual component 10 evaporates due to heat to form water vapor, which will cause the mirror of the camera 300 to fog, thereby hindering the normal operation of the camera 300. An electrolytic humidity control valve 500 is set and fixed to the shell 100 or the back cover 200, and the cathode plate 510 and the anode plate 520 of the electrolytic humidity control valve 500 are accommodated in the accommodating cavity 600. The cathode plate 510 and the anode plate 520 are electrically connected to the circuit board 400, so that the circuit board 400 in the visual component 10 can provide current to the electrolytic humidity control valve 500, so that the electrolytic humidity control valve 500 can work to electrolyze the water vapor in the accommodating cavity 600 and discharge the particles formed by electrolysis out of the accommodating cavity 600, thereby reducing the water vapor in the accommodating cavity 600, thereby avoiding fogging of the camera 300 and ensuring the normal operation of the visual component 10.

[0053] In one embodiment, if Figure 3 As shown, the visual assembly 10 further includes a lens transparent plate 700 , which is disposed on a side of the first side plate 110 of the housing 100 facing away from the accommodating cavity 600 . The first side plate 110 and the back cover 200 are arranged opposite each other along the first direction Y. The projection of the lens transparent plate 700 along the first direction Y covers the camera hole 111 .

[0054] In the embodiment of the present application, the lens transparent plate 700 can protect the camera 300 without affecting the normal operation of the camera 300.

[0055] In one embodiment, if Figure 4 and Figure 6 As shown, the rear cover 200 includes a first opening 201, and the electrolytic humidity control valve 500 further includes a valve housing 530. The valve housing 530 is used to fix the cathode plate 510 and the anode plate 520. The valve housing 530 is provided through the first opening 201. Figure 3 As shown, the cathode plate 510 and the anode plate 520 protrude from the valve housing 530 toward the interior of the accommodating chamber 600 .

[0056] In the embodiment of the present application, the rear cover 200 includes a first opening 201 , which provides an installation space for the valve housing 530 of the electrolytic humidity control valve 500 , so that the electrolytic humidity control valve 500 can be installed on the rear cover 200 .

[0057] In an embodiment of the present application, the cathode plate 510 and the anode plate 520 protrude from the valve housing 530 toward the interior of the accommodating cavity 600, so that the anode plate 520 and the cathode plate 510 can be electrically connected to the circuit board 400 in the accommodating cavity 600, so that current can be transmitted to the electrolytic humidity control valve 500, so that the electrolytic humidity control valve 500 works, electrolyzes the water vapor in the accommodating cavity 600 and discharges it out of the accommodating cavity 600, reduces the water vapor in the accommodating cavity 600, and keeps the air in the accommodating cavity 600 dry, thereby reducing the fogging of the camera 300 and ensuring the normal operation of the visual component 10.

[0058] In one embodiment, if Figure 4 and Figure 5 As shown, the circuit board 400 and the back cover 200 are arranged opposite to each other along the first direction Y, the thickness direction of the circuit board 400 is parallel to the first direction Y, and the cathode plate 510 and the anode plate 520 protrude from the valve housing 530 toward the circuit board 400.

[0059] In an embodiment of the present application, the circuit board 400 and the back cover 200 are arranged relative to each other along a first direction Y, the thickness direction of the circuit board 400 is parallel to the first direction Y, and the valve shell 530 of the electrolytic humidity control valve 500 is passed through the first opening 201 of the back cover 200, so that the circuit board 400 and the electrolytic humidity control valve 500 are arranged relative to each other along the first direction Y, and the cathode plate 510 and the anode plate 520 protrude from the valve shell 530 toward the circuit board 400, which facilitates the electrical connection between the cathode plate 510 and the anode plate 520 and the circuit board 400, which is beneficial to shortening the electrical connection path between the electrolytic humidity control valve 500 and the circuit board 400, and simplifying the cable arrangement in the visual component 10.

[0060] In one embodiment, if Figure 4 and Figure 5 As shown, the circuit board 400 includes a surface 410 facing the back cover 200 . The surface 410 includes two connecting terminals (not shown). The two connecting terminals are electrically connected to the cathode plate 510 and the anode plate 520 respectively.

[0061] In one embodiment, the back cover 200 further includes a first groove 202. Figure 4 As shown, the notch of the first groove 202 faces away from the first side plate 110 along the first direction Y, and the first opening 201 passes through the bottom of the first groove 202 along the first direction Y, as shown in FIG. Figure 6 As shown, the valve housing 530 includes a mounting surface 531 , which is fixed to the bottom of the first groove 202 .

[0062] In the embodiment of the present application, the notch of the first groove 202 is oriented away from the first side plate 110 along the first direction Y, thereby facilitating smoother installation of the valve housing 530 of the electrolytic humidity control valve 500 within the first groove 202 of the rear cover 200. The first opening 201 extends through the bottom of the first groove 202 along the first direction Y. The valve housing 530 includes a mounting surface 531 that is secured to the bottom of the first groove 202. This allows the valve housing 530 to be not only inserted through the first opening 201 but also secured to the rear cover 200 via the first groove 202. This provides for a more secure fixation of the valve housing 530 of the electrolytic humidity control valve 500, thereby further strengthening the electrical connection between the cathode and anode plates 510 and 520 secured by the valve housing 530 and the circuit board 400. This helps ensure the proper dehumidification of the electrolytic humidity control valve 500, thereby keeping the interior of the accommodating chamber 600 dry and preventing fogging of the camera 300.

[0063] In one embodiment, along the first direction Y, the depth of the first groove 202 is less than the thickness of the back cover 200 , so that the first groove 202 does not affect the overall strength of the back cover 200 when it is formed in the back cover 200 .

[0064] Figure 7 This is another schematic diagram of the visual component 10 provided in an embodiment of the present application.

[0065] In one embodiment, the housing 100 includes a first protrusion 120, such as Figure 5 and Figure 7 As shown, the first protrusion 120 protrudes from the opening 101 of the housing 100 away from the first side plate 110 along the first direction Y. The first protrusion 120 is used to fix the housing 20 of the lawn mower 1. In the first direction Y, the distance between the end of the first protrusion 120 away from the first side plate 110 and the opening 101 of the housing 100 is greater than the distance between the end of the electrolytic humidity control valve 500 away from the first side plate 110 and the opening 101 of the housing 100.

[0066] In an embodiment of the present application, the first protrusion 120 protrudes from the opening 101 of the shell 100 away from the first side panel 110 along the first direction Y, so that the visual component 10 can be fixed to the housing 20 of the lawn mower 1 at the rear opposite to the camera 300 along the first direction Y, and can enable the camera 300 to always remain in front of the movement direction of the lawn mower 1.

[0067] In the embodiments of this application, Figure 7As shown, the distance between the end of the first protrusion 120 away from the first side plate 110 and the opening 101 of the shell 100 along the first direction Y is recorded as L1, and the distance between the end of the electrolytic humidity control valve 500 away from the first side plate 110 and the opening 101 of the shell 100 is recorded as L2. The first protrusion 120 is used to fix the shell 20 of the lawn mower 1. L1>L2, so that there is a gap between the electrolytic humidity control valve 500 and the shell 20, ensuring that the discharge path of the particles after the electrolysis of water vapor in the accommodating chamber 600 is not blocked, so that the particles after electrolysis of the electrolytic humidity control valve 500 can be smoothly discharged from the accommodating chamber 600 to the gap between the electrolytic humidity control valve 500 and the shell 20, and then discharged from the lawn mower 1. L1>L2, and also makes it possible for the first protrusion 120 to shield the electrolytic humidity control valve 500 in the height direction of the lawn mower 1, thereby reducing the water above the lawn mower 1 from flowing into the accommodating cavity 600 through the installation gap between the electrolytic humidity control valve 500 and the back cover 200, which is beneficial to maintaining a dry environment in the accommodating cavity 600, reducing fogging of the camera 300, and facilitating the normal operation of the visual component 10.

[0068] Figure 8 It is a schematic diagram of a visual component 100 provided in another embodiment of the present application.

[0069] In one embodiment, if Figure 8 As shown, the housing 100 further includes two second side panels 130, which are arranged opposite to each other along a second direction X, and the second direction X is perpendicular to the first direction Y. One of the second side panels 130 includes a second opening 131, and the second opening 131 passes through the second side panel 130 along the second direction X. Figure 6 and Figure 8 As shown, the electrolytic humidity control valve 500 further includes a valve housing 530, which is used to fix the cathode plate 510 and the anode plate 520. The valve housing 530 is provided through the second opening 131, and the cathode plate 510 and the anode plate 520 protrude from the valve housing 530 toward the interior of the accommodating cavity 600. Figure 5 and Figure 8 As shown, the second openings 131 are arranged between the circuit board 400 and the back cover 200 along the first direction Y.

[0070] In the embodiment of the present application, a second side plate 130 includes a second opening 131 , and the second opening 131 penetrates the second side plate 130 along the second direction X, thereby providing space for the valve housing 530 to pass through the second side plate 130 .

[0071] In an embodiment of the present application, the valve housing 530 is used to fix the cathode plate 510 and the anode plate 520. The valve housing 530 is passed through the second opening 131. The cathode plate 510 and the anode plate 520 protrude from the valve housing 530 toward the interior of the accommodating cavity 600, so that the anode plate 520 and the cathode plate 510 can be electrically connected to the circuit board 400 in the accommodating cavity 600, so that current can be transmitted to the electrolytic humidity control valve 500, so that the electrolytic humidity control valve 500 works, electrolyzes the water vapor in the accommodating cavity 600 and discharges it from the accommodating cavity 600, thereby reducing the water vapor in the accommodating cavity 600 and keeping the air in the accommodating cavity 600 dry, thereby reducing the fogging of the camera 300 and ensuring the normal operation of the visual component 10.

[0072] In the embodiment of the present application, the second opening 131 is arranged between the circuit board 400 and the back cover 200 along the first direction Y, so that the valve shell 530 passing through the second opening 131 will not interfere with the circuit board 400 in the accommodating cavity 600, which is conducive to a more reasonable and regular arrangement of components in the visual component 10.

[0073] In one embodiment, a second side plate 130 further includes a second groove 133, such as Figure 6 and Figure 8 As shown, the notch of the second groove 133 faces away from the accommodating chamber 600 along the second direction X, and the second opening 131 passes through the bottom of the second groove 133. The second groove 133 is used to accommodate the mounting surface 531 of the fixed valve housing 530, and the second opening 131 is used to penetrate the cathode plate 510 and the anode plate 520 of the electrolytic humidity control valve 500.

[0074] In the embodiment of the present application, the notch of the second groove 133 faces away from the accommodating chamber 600 along the second direction X, thereby facilitating smoother installation of the valve housing 530 of the electrolytic humidity control valve 500 in the second groove 133 of a second side plate 130. The second opening 131 extends through the bottom of the second groove 133. The second groove 133 is used to accommodate the mounting surface 531 for fixing the valve housing 530. This allows the valve housing 530 to not only be installed on a second side plate 130 through the second opening 131, but also to be fixed to a second side plate 130 through the second groove 133. This makes the valve housing 530 of the electrolytic humidity control valve 500 more securely fixed, thereby further strengthening the electrical connection between the cathode plate 510 and the anode plate 520 fixed by the valve housing 530 and the circuit board 400. This helps ensure the normal dehumidification operation of the electrolytic humidity control valve 500, thereby ensuring dryness within the accommodating chamber 600 and preventing fogging of the camera 300.

[0075] In one embodiment, a second side plate 130 further includes a second protrusion 132, such as Figure 8As shown, the second protrusion 132 protrudes from a second side plate 130 away from the accommodating cavity 600 along the second direction X, and the length direction A of the second protrusion 132 intersects with the first direction Y. The shell 100 also includes a top plate 140 and a bottom plate 150. The top plate 140 and the bottom plate 150 are arranged relative to each other along a third direction Z. The third direction Z is perpendicular to the first direction Y and the second direction X. Along the third direction Z, the bottom plate 150, the second opening 131, and the second protrusion 132 are arranged in sequence.

[0076] In the embodiment of the present application, the second protrusion 132 protrudes from a second side plate 130 away from the accommodating cavity 600 along the second direction X, and the length direction A of the second protrusion 132 intersects with the first direction Y, so that the second protrusion 132 can be arranged at an angle on a second side plate 130, which is conducive to draining water falling from the top plate 140 of the lawn mower 1 and reducing water accumulation on the housing 100 of the visual component 10. Along the third direction Z, the bottom plate 150, the second opening 131, and the second protrusion 132 are arranged in sequence, so that along the third direction Z, the second protrusion 132 can block the second opening 131, and the valve housing 530 is penetrated through the second opening 131, so that along the third direction Z, the second protrusion 132 can block the electrolytic humidity control valve 500, thereby reducing the water on the top plate 140 of the lawn mower 1 from flowing into the accommodating cavity 600 through the installation gap between the electrolytic humidity control valve 500 and a second side plate 130, which is beneficial to maintaining a dry environment in the accommodating cavity 600, reducing fogging of the camera 300, and facilitating the normal operation of the visual component 10.

[0077] In one embodiment, the second protrusion 132 separates the second side plate 130 into two parts 134 and 135 along the third direction Z. Figure 8 As shown, a portion 134 of a second side plate 130, a second protrusion 132, and another portion 135 of a second side plate 130 are sequentially arranged along the third direction Z. The area of ​​the other portion 135 of a second side plate 130 is larger than the area of ​​the portion 134 of a second side plate 130. Along the second direction X, the projection of the other portion 135 of a second side plate 130 overlaps the projection of the electrolytic humidity control valve 500. This leaves more space in the other portion 135 of the second side plate 130 for installing and arranging the electrolytic humidity control valve 500.

[0078] In one embodiment, the second protrusion 132 is used to fix the housing 20 of the lawn mower 1 .

[0079] Figure 9 This is another schematic diagram of the visual component 10 provided in an embodiment of the present application.

[0080] In one embodiment, the visual assembly 10 further includes an adapter 800, such as Figure 5 and Figure 9As shown, a portion of the adapter 800 is accommodated in the accommodating cavity 600, and the adapter 800 is electrically connected to the cathode plate 510 and the anode plate 520 of the electrolytic humidity control valve 500 through the circuit board 400. The shell 100 also includes a top plate 140 and a bottom plate 150. The top plate 140 and the bottom plate 150 are arranged relatively to each other along the third direction Z. The bottom plate 150 includes a third opening 151. The third opening 151 passes through the bottom plate 150 along the third direction Z. The third opening 151 is used to pass the adapter 800.

[0081] In an embodiment of the present application, a portion of the adapter 800 is accommodated in the accommodating cavity 600, which facilitates the electrical connection between the adapter 800 and the circuit board 400 in the accommodating cavity 600. The adapter 800 is electrically connected to the cathode plate 510 and the anode plate 520 of the electrolytic humidity control valve 500 through the circuit board 400, so that the current transmitted by the adapter 800 can provide current to the anode plate 520 and the cathode plate 510 of the electrolytic humidity control valve 500, so that the electrolytic humidity control valve 500 performs water vapor electrolysis, thereby reducing the water vapor in the accommodating cavity 600, maintaining a dry environment in the accommodating cavity 600, and reducing the fogging of the camera 300.

[0082] In the embodiment of the present application, the base plate 150 includes a third opening 151 that extends through the base plate 150 along the third direction Z, providing space for the adapter 800 to be inserted through the third opening 151. Furthermore, the base plate 150 of the vision assembly 10 is fixed to the housing 20 of the lawn mower 1, thereby preventing the adapter 800 from being exposed outside the lawn mower 1, facilitating the normal operation of the adapter 800. The third opening 151 is used to insert the adapter 800, allowing the adapter 800 to be electrically connected to the vision mainboard within the housing 20 after the vision assembly 10 is installed, thereby transmitting information collected by the camera 300.

[0083] In one embodiment, if Figure 6 As shown, the electrolytic humidity control valve 500 further includes a valve housing 530, a waterproof and breathable membrane 540, and an electrolyte membrane 550. The valve housing 530 includes a central hole 532 and a placement groove 533. The central hole 532 is located in the center of the valve housing 530, and the placement groove 533 is located on the side of the valve housing 530 facing away from the accommodating chamber 600. The waterproof and breathable membrane 540 is disposed within the placement groove 533 and aligned with the central hole 532. The cathode plate 510, electrolyte membrane 550, and anode plate 520 are sequentially installed within the valve housing 530.

[0084] In this embodiment of the present application, the valve housing 530 includes a central hole 532 and a placement groove 533. The central hole 532 is located in the middle of the valve housing 530 and provides a passage for particles generated by electrolysis in the electrolytic humidity control valve 500 to exit the receiving chamber 600. When the cathode plate 510 and the anode plate 520 are energized, the electrolyte membrane 550 sandwiched between the cathode plate 510 and the anode plate 520 can be activated to decompose the water vapor in the receiving chamber 600 into hydrogen ions and oxygen. Under the action of the current flowing through the cathode plate 510 and the anode plate 520, the hydrogen ions move to the side of the electrolyte membrane 550 facing away from the receiving chamber 600 along the first direction Y. There, the hydrogen ions can undergo an oxidation reaction with external oxygen to regenerate water molecules, which are then dissipated into the external environment, achieving a one-way, irreversible dehumidification effect. The oxygen molecules in the receiving chamber 600 can then exit the receiving chamber 600 through the central hole 532 and the waterproof and breathable membrane 540 disposed within the placement groove 533, maintaining the air pressure balance within the receiving chamber 600.

[0085] In one embodiment, the cathode sheet 510 includes a main body 511 and a connecting portion 512, and the anode sheet 520 includes a main body 521 and a connecting portion 522. The main body 511 of the cathode sheet 510, the electrolyte membrane 550, and the main body 521 of the anode sheet 520 are stacked and installed in sequence in the valve housing 530. The connecting portion 512 of the cathode sheet 510 and the connecting portion 522 of the anode sheet 520 protrude toward the accommodating cavity 600, providing a connection portion for the cathode sheet 510 and the anode sheet 520 to be connected to the circuit board 400, which is conducive to the electrical connection between the cathode sheet 510 and the anode sheet 520 and the circuit board 400 in the accommodating cavity 600.

[0086] In one embodiment, the electrolyte membrane 550 is composed of carbon paper, a proton exchange membrane, PTFE, a metal mesh and a catalyst. It has a front and a back side. The catalyst side is the front side, which is the wet side and faces the inside of the accommodating cavity 600. The carbon paper side is the back side, which is the dehumidification side and faces away from the accommodating cavity 600. It mainly decomposes water molecules and conducts hydrogen ions. The hydrogen ions move from the wet side to the dehumidification side.

[0087] In one embodiment, the electrolyte membrane 550 has a length of 7.1 mm and a width of 7.1 mm.

[0088] In one embodiment, the electrolytic humidity control valve 500 further includes buffer silica gel (not shown), and the buffer silica gel, the cathode plate 510 , the electrolyte membrane 550 and the anode plate 520 are sequentially installed in the valve housing 530 .

[0089] In one embodiment, the electrolytic moisture control valve 500 also includes a sealing ring 560, which is arranged on the side of the valve shell 530 facing the accommodating cavity 600. The sealing ring 560 is used to make the installation and fixation of the mounting surface 531 of the valve shell 530 and the shell 100 more sealed, thereby reducing the water vapor outside the visual component 10 from penetrating into the accommodating cavity 600 through the installation gap between the valve shell 530 and the shell 100.

[0090] In one embodiment, the vision assembly 10 further includes a plastic gland 570, which is located outside the cathode plate 510. The valve housing 530 further includes a buckle 534. The plastic gland 570 includes a slide 571 and a clamping groove 572. The slide 571 is formed on the side wall of the plastic gland 570 and is slidably connected to the buckle 534. The slide 571 and the clamping groove 572 are connected, and the clamping groove 572 is detachably connected to the buckle 534, so that the buckle 534 can fix or remove the plastic gland 570 from the valve housing 530.

[0091] In one embodiment, the vision assembly 10 further includes a humidity sensor (not shown) configured to detect the humidity of the air within the housing chamber 600 of the vision assembly 10. When the humidity sensor detects that the humidity within the housing chamber 600 exceeds a preset threshold, it transmits a detection signal to the vision mainboard of the vision assembly 10 via the circuit board 400. Upon receiving the excessive humidity detection signal, the vision mainboard supplies power to the electrolytic humidity control valve 500 via the circuit board 400, causing the electrolytic humidity control valve 500 to begin electrolysis. When the humidity detected by the temperature sensor falls below a preset threshold, the electrolytic humidity control valve 500 ceases operation.
