Technical Field
[0001] This application relates to the technical field, and in particular to a vision component for a lawnmower. Background Technology
[0002] A lawnmower is a tool that automates lawn mowing, replacing manual labor. Lawnmowers typically include a vision module, which senses the environment within the work area, identifies obstacles, and performs dynamic path planning and navigation. However, because lawnmowers operate outdoors for extended periods, water from outside can easily seep into the vision module's cavity. The lawnmower generates a significant amount of heat during operation, causing the water inside the vision module to vaporize and condense on the camera components, thus affecting the module's normal operation. Utility Model Content
[0003] This application provides a vision component for a lawnmower.
[0004] This application provides a vision component for a lawnmower. The vision component includes a housing, a rear cover, a camera assembly, a humidity control valve, and a dehumidifier. The rear cover is used to enclose a cavity with the housing. The housing includes a first side plate, which is arranged opposite to the rear cover along a first direction. The first side plate includes a camera hole that penetrates the first side plate along the first direction. The camera assembly is housed within the cavity, and the camera assembly and camera hole are arranged along the first direction. The humidity control valve is used to balance the pressure difference between the cavity and the external environment. The dehumidifier absorbs moisture from the cavity and is housed within it. The humidity control valve and the dehumidifier are spaced apart from the camera assembly. The dehumidifier and the humidity control valve are fixed to the side wall of the housing or the rear cover.
[0005] In this embodiment, the first side plate includes a camera hole that extends through the first side plate along a first direction, so that the field of view of the camera component aligned with the camera hole is not blocked by the first side plate, allowing the camera component to normally survey the working environment.
[0006] In this embodiment, the humidity control valve and dehumidifier are spaced apart from the camera assembly, ensuring that their arrangement does not interfere with the camera assembly. The spaced arrangement also prevents moisture absorbed by the dehumidifier from condensing on the camera assembly after being released due to temperature increases.
[0007] In this embodiment, the humidity control valve is fixed to the side wall or rear cover of the housing, which reduces the inflow of water from the external environment into the receiving cavity through the gap between the humidity control valve and the first side plate. Fixing the dehumidifier to the side wall or rear cover of the housing eliminates the need to consider whether the dehumidifier's placement interferes with the camera hole on the first side plate, thus affecting the normal operation of the camera assembly. Fixing the dehumidifier to the first side plate would trap it between the camera assembly and the first side plate, making it difficult to replace.
[0008] In this embodiment, the camera component is housed within a cavity. During operation, water inside the vision component evaporates due to heat, forming water vapor that can cause fogging and hinder normal operation. A humidity control valve allows air and some water vapor to escape from the cavity when the water expands due to heat, increasing the internal pressure. This reduces the water vapor content and the probability of condensation, promoting normal operation. The valve also allows for ventilation only when the external pressure is higher than the cavity pressure, reducing the frequency of air exchange and minimizing the amount of moisture entering the cavity. Furthermore, a dehumidifier absorbs moisture that cannot escape through the valve, further reducing condensation and ensuring proper functioning of the vision component.
[0009] In one embodiment, the humidity control valve is fixed to the rear cover, and the humidity control valve, the camera assembly, and the first side plate are arranged sequentially at intervals along the first direction.
[0010] In this embodiment, the humidity control valve is fixed to the rear cover, which reduces the seepage of water from the external environment into the receiving cavity through the installation gap between the humidity control valve and the rear cover. The humidity control valve, camera assembly, and first side plate are arranged sequentially at intervals, so that the setting of the humidity control valve will not affect the arrangement of the camera assembly, which is conducive to the orderly arrangement of the vision components.
[0011] In one embodiment, the housing includes an opening for enclosing a rear cover and forming a receiving cavity with the housing. A dehumidifying plate is fixed to the side wall of the housing. A humidity control valve, the dehumidifying plate, and a camera assembly are arranged at intervals along a first direction. Along the first direction, the distance between the dehumidifying plate and the opening is less than the distance between the dehumidifying plate and the camera assembly.
[0012] In this embodiment, the dehumidifier is fixed to the side wall of the housing, and the humidity control valve, the dehumidifier, and the camera assembly are arranged at intervals along the first direction, so that the water vapor entering the containment cavity through the humidity control valve can be dehumidified by the dehumidifier before contacting the camera assembly, thereby reducing the probability of condensation on the camera assembly.
[0013] In this embodiment of the application, along the first direction, the distance between the dehumidifying plate and the opening is less than the distance between the dehumidifying plate and the camera assembly, so that the dehumidifying plate is positioned closer to the opening of the housing, thereby allowing water that seeps into the receiving cavity from the gap between the rear cover and the housing to be absorbed by the dehumidifying plate more quickly, reducing the humidity in the receiving cavity, which helps to reduce the probability of condensation on the camera assembly, extend the service life of the vision assembly and improve its operational safety.
[0014] In one embodiment, the housing includes an opening for enclosing the rear cover and the housing to form a receiving cavity, a dehumidifying plate is fixed to the inner wall of the rear cover and close to the opening, and the dehumidifying plate is spaced apart from the humidity control valve.
[0015] In this embodiment, the dehumidifier is fixed to the inner wall of the back cover. When the dehumidifier needs to be replaced, simply open the back cover; the operation is simple. The dehumidifier is spaced apart from the humidity control valve, ensuring that the dehumidifier does not affect the ventilation of the humidity control valve. This allows the humidity control valve to promptly balance the pressure difference between the cavity containing the vision component and the external environment.
[0016] In this embodiment, the dehumidifying plate is arranged near the opening of the housing, which allows water that seeps in from the opening of the housing to be absorbed by the dehumidifying plate more quickly, reducing the humidity in the housing cavity. This helps to reduce the probability of condensation on the camera component, extend the service life of the vision component, and improve its operational safety.
[0017] In one embodiment, the humidity control valve is fixed to the side wall of the housing, and the rear cover, humidity control valve, and camera assembly are arranged at intervals along the first direction.
[0018] In this embodiment, the humidity control valve is fixed to the side wall of the housing, so that the arrangement of the humidity control valve will not affect the arrangement of the camera assembly on the first side plate, and it is also convenient for the humidity control valve to be installed and removed directly from the side wall of the housing.
[0019] In this embodiment, the rear cover, humidity control valve, and camera assembly are arranged at intervals along the first direction, so that the arrangement of the humidity control valve and the camera assembly will not interfere with each other, and the arrangement of the devices in the cavity of the vision assembly is reasonable and orderly.
[0020] In one embodiment, the dehumidifying sheet is fixed to the side wall or rear cover of the housing, and the rear cover, the dehumidifying sheet and the camera assembly are arranged at intervals along a first direction.
[0021] In this embodiment, the dehumidifier absorbs water from the cavity. The back cover, the dehumidifier, and the camera assembly are arranged at intervals along the first direction, so that there is a certain distance between the dehumidifier and the camera assembly. This prevents the water vapor released by the dehumidifier due to temperature rise from quickly condensing on the camera assembly, reducing the probability of condensation on the camera assembly and ensuring the normal operation of the vision assembly.
[0022] In one embodiment, the housing includes an opening for enclosing a rear cover and housing to form a receiving cavity, wherein a dehumidifying plate, a humidity control valve, and a camera assembly are spaced apart along a first direction. Along the first direction, the distance between the dehumidifying plate and the opening is less than the distance between the dehumidifying plate and the humidity control valve.
[0023] In this embodiment, the dehumidifying sheet, the humidity control valve, and the camera assembly are arranged at intervals along the first direction, so that the dehumidifying sheet can not only quickly absorb the water vapor that enters the receiving cavity through the humidity control valve, but also quickly absorb the water from the external environment that seeps in from the opening of the housing, thereby reducing the humidity in the receiving cavity and thus helping to reduce the probability of condensation on the camera assembly.
[0024] In this embodiment, along the first direction, the distance between the dehumidifying plate and the opening is less than the distance between the dehumidifying plate and the humidity control valve, so that the dehumidifying plate is arranged closer to the opening, which is conducive to the dehumidifying plate absorbing water that seeps into the receiving cavity from the opening of the housing more quickly, thereby helping to reduce the humidity in the receiving cavity and reduce the probability of condensation on the camera component.
[0025] In one embodiment, the housing further includes an opening and a first protrusion. The opening is used to enclose the rear cover and the housing to form a receiving cavity. The first protrusion protrudes from the opening away from the first side plate along a first direction and is used to fix the housing of the lawnmower. The distance between the end of the first protrusion away from the first side plate and the opening along the first direction is greater than the distance between the end of the humidity control valve away from the first side plate and the opening.
[0026] In this embodiment of the application, the first protrusion protrudes from the opening away from the first side plate along the first direction, so that the vision component can be fixed to the housing of the lawnmower at the rear opposite to the camera component along the first direction, and the camera component can always be kept in front of the lawnmower in the direction of movement.
[0027] In this embodiment, the distance between the end of the first protrusion facing away from the first side plate and the opening along the first direction is greater than the distance between the end of the humidity control valve facing away from the first side plate and the opening. This creates a gap between the humidity control valve and the housing, allowing the humidity control valve to ventilate with the external environment to balance the pressure difference between the receiving cavity and the external environment. The greater distance between the end of the first protrusion facing away from the first side plate and the opening along the first direction also allows the first protrusion to shield the humidity control valve in the height direction of the lawnmower. This reduces the amount of water flowing into the receiving cavity from above the lawnmower through the installation gap between the humidity control valve and the rear cover, helping to maintain a dry environment inside the receiving cavity, reducing camera fogging, and facilitating the normal operation of the vision components.
[0028] In one embodiment, one of the sidewalls of the housing and the rear cover includes a first opening, and the humidity control valve includes a pressure control element and a vent connected to each other, the vent passing through the first opening, and the pressure control element located on an inner side facing the receiving cavity.
[0029] In this embodiment, one of the side wall and the rear cover of the housing includes a first opening, allowing the humidity control valve to be installed and fixed to the side wall or the rear cover of the housing.
[0030] In this embodiment, a vent is inserted through the first opening, allowing the vent to connect the receiving cavity to the external environment, thus enabling the humidity control valve to balance the pressure difference between the receiving cavity and the external environment. A pressure control element is located on the inner side facing the receiving cavity, allowing it to contact the gas inside the cavity. The cooperation between the pressure control element and the vent allows gas to be discharged from the receiving cavity when the pressure inside the cavity is higher than that of the external environment, and also allows outside air to be introduced into the receiving cavity when the pressure inside the cavity is lower than that of the external environment, thereby balancing the pressure difference between the receiving cavity and the external environment.
[0031] In one embodiment, the humidity control valve further includes a pressure control element, a venting section, and a waterproof and breathable membrane. The waterproof and breathable membrane is disposed on the side of the venting section away from the receiving cavity, and the pressure control element is disposed on the side of the venting section facing the receiving cavity. The waterproof and breathable membrane, the venting section, the pressure control element, and the camera assembly are spaced apart.
[0032] In this embodiment, the waterproof and breathable membrane can reduce the humidity of the containment cavity by allowing moisture from the external environment to enter through the humidity control valve, thereby reducing the intake of moisture and the amount of moisture in the containment cavity.

[0044] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0045] In this document, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.
[0046] Furthermore, in this article, directional terms such as "upper" and "lower" are defined relative to the orientation of the structure as shown in the attached drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the structure.
[0047] This application provides a vision component for a lawnmower, including a housing, a rear cover, a camera assembly, a humidity control valve, and a dehumidifier plate. The rear cover is used to enclose a receiving cavity with the housing. The housing includes a first side plate, which is arranged opposite to the rear cover along a first direction. The first side plate includes a camera hole that penetrates through the first side plate along the first direction. The camera assembly is housed within the receiving cavity, and the camera assembly and camera hole are arranged along the first direction. The humidity control valve is used to balance the internal and external pressure difference between the receiving cavity and the external environment. The dehumidifier plate is used to absorb moisture in the receiving cavity and is housed within the receiving cavity. The humidity control valve and the dehumidifier plate are spaced apart from the camera assembly, and the dehumidifier plate and the humidity control valve are fixed to the side wall of the housing or the rear cover.
[0048] This application fixes the dehumidifier and humidity control valve to the side wall or rear cover of the housing. The humidity control valve balances the air pressure inside the vision component's housing with the external air pressure. The valve is designed to open only when the external pressure is higher than the internal pressure, allowing humid air to enter and reducing the frequency of air exchange. This reduces the amount of moisture entering the vision component's housing. The dehumidifier absorbs this moisture, further reducing the probability of condensation on the camera module. This extends the lifespan of the vision component and improves operational safety.
[0049] The vision component provided in this application embodiment is applied to a lawnmower to improve the overall performance of the lawnmower.
[0050] Figure 1 This is a schematic diagram of a lawnmower 1 provided in an embodiment of this application.
[0051] In one embodiment, a lawnmower 1 includes a housing 10, a vision component 20, and a walking mechanism 30, such as... Figure 1 As shown, the vision component 20 is fixed to the top of the housing 10, and the walking device 30 is used to drive the lawnmower 1 to move.
[0052] When lawnmowers operate outdoors for extended periods, water can seep into the vision components. Furthermore, the large amount of heat generated during lawnmower operation causes the water inside the vision component's housing to evaporate, forming water vapor. Since the camera is housed in the housing, this causes the camera lens to fog up, hindering the camera's normal operation.
[0053] The vision component in this application fixes the dehumidifying sheet and the humidity control valve to the side wall or rear cover of the housing. The humidity control valve balances the air pressure inside the housing cavity of the vision component with the air pressure of the external environment, which helps to keep the housing cavity a sealed space and reduce the inflow of water from the external environment into the housing cavity of the vision component. The dehumidifying sheet absorbs the moisture inside the vision component, so that the moisture will not condense on the camera component, which helps to extend the service life of the vision component and improve its operational safety.
[0054] Figure 2 This is a schematic diagram of a vision component 20 provided in an embodiment of this application. Figure 3 This is an exploded view of the visual component 20 provided in an embodiment of this application. Figure 4 This is another exploded view of the visual component 20 provided in the embodiments of this application.
[0055] In one embodiment, such as Figures 2 to 4 As shown, a vision component 20 of a lawnmower 1 includes a housing 100, a rear cover 200, a camera component 300, a humidity control valve 400, and a dehumidifier 500. The rear cover 200 is used to enclose a receiving cavity 600 with the housing 100. The housing 100 includes a first side plate 110, and the first side plate 110 and the rear cover 200 are arranged opposite each other along a first direction Y. The first side plate 110 includes a camera hole 111, which penetrates the first side plate 110 along the first direction Y. The camera component 300 is housed within the receiving cavity 600, and the camera component 300 and the camera hole 111 are arranged along the first direction Y. The humidity control valve 400 is used to balance the internal and external pressure difference between the housing 600 and the external environment. The dehumidification plate 500 is used to absorb water vapor in the housing 600. The dehumidification plate 500 is housed in the housing 600. The humidity control valve 400 and the dehumidification plate 500 are spaced apart from the camera assembly 300. The dehumidification plate 500 and the humidity control valve 400 are fixed to the side wall 120 or the rear cover 200 of the housing 100.
[0056] In this embodiment of the application, the first side plate 110 includes a camera hole 111, which penetrates the first side plate 110 along the first direction Y, so that the field of view of the camera component 300 aligned with the camera hole 111 is not blocked by the first side plate 110, and the camera component 300 can normally survey the working environment.
[0057] In this embodiment, the humidity control valve 400 and the dehumidifying plate 500 are spaced apart from the camera assembly 300, ensuring that their arrangement does not interfere with the camera assembly 300. The spaced-apart arrangement of the dehumidifying plate 500 from the camera assembly 300 also prevents moisture absorbed by the dehumidifying plate 500 from condensing on the camera assembly 300 after being released due to temperature increases.
[0058] In this embodiment, the humidity control valve 400 is fixed to the side wall 120 or the rear cover 200 of the housing 100, which can reduce the inflow of water from the external environment into the receiving cavity 600 through the gap between the humidity control valve 400 and the first side plate 110. The dehumidifier 500 is fixed to the side wall 120 or the rear cover 200 of the housing 100, eliminating the need to consider whether the dehumidifier 500's placement interferes with the camera hole 111 on the first side plate 110, thus affecting the normal operation of the camera assembly 300. If the dehumidifier 500 is fixed to the first side plate 110, it would be sandwiched between the camera assembly 300 and the first side plate 110, making replacement of the dehumidifier 500 difficult.
[0059] In this embodiment, the camera component 300 is housed within the housing cavity 600. During the operation of the lawnmower 1, the water in the vision component 20 evaporates due to heat, forming water vapor, which can cause fogging of the camera component 300, thus hindering its normal operation. The humidity control valve 400 can discharge the air and some water vapor from the housing cavity 600 through the humidity control valve 400 when the water expands due to heat, causing the air pressure inside the housing cavity 600 to be greater than the external ambient air pressure. This reduces the water vapor content inside the housing cavity 600, thereby reducing the probability of condensation on the camera component 300 and facilitating its normal operation. The humidity control valve 400 is designed to open only when the external ambient pressure is higher than the pressure inside the containment cavity 600, allowing humid air to enter. This reduces the frequency of air exchange, thereby reducing the amount of moisture entering the containment cavity 600 of the vision component 20 and reducing the amount of moisture inside the containment cavity 600. The dehumidifying plate 500 absorbs moisture that cannot be discharged from the containment cavity 600 through the humidity control valve 400, further reducing the amount of moisture inside the containment cavity 600. This reduces the probability of condensation on the camera component 300 and ensures the normal operation of the vision component 20.
[0060] It should be noted that the first side plate 110 is part of the side wall 120 of the housing 100. The camera assembly 300 is partially fixed to the first side plate 110. If the humidity control valve 400 is fixed to the first side plate 110, the water vapor entering the humidity control valve 400 can easily condense directly on the camera assembly 300. Therefore, it is clearly not feasible to fix the humidity control valve 400 to the first side plate 110.
[0061] In one embodiment, the dehumidifier 500 is glued to the side wall 120 or the rear cover 200 of the housing 100. The number of dehumidifiers 500 may be one or more.
[0062] In one embodiment, the dehumidifier 500 can be made of synthetic rubber, flame-retardant and high-temperature resistant non-woven fabric, activated carbon, calcium chloride, graphene, silicone, etc. During the operation of the lawnmower 1, a large amount of heat is generated, causing the temperature of the vision component 20 to rise. The water in the receiving cavity 600 evaporates into water vapor, making the pressure inside the receiving cavity 600 higher than the external ambient pressure. The humidity control valve 400 opens, allowing air and some water vapor inside the receiving cavity 600 to be discharged. When the temperature inside the receiving cavity 600 reaches above 40 degrees Celsius, approximately 10% of the water vapor contained in the dehumidifier 500 can evaporate and be released. The moisture absorbed by the dehumidifier 500 is then discharged through the humidity control valve 400, thereby extending the service life of the dehumidifier 500 and reducing its replacement frequency.
[0063] In one embodiment, such as Figure 3 As shown, the vision assembly 20 also includes a lens transparent plate 700, which is disposed on the side of the first side plate 110 of the housing 100 opposite to the receiving cavity 600. The first side plate 110 and the rear 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.
[0064] In this embodiment, the lens transparent plate 700 can protect the camera component 300 without affecting its normal operation.
[0065] In one embodiment, such as Figure 3 and Figure 4 The humidity control valve 400 is fixed to the rear cover 200, and along the first direction Y, the humidity control valve 400, the camera assembly 300, and the first side plate 110 are arranged in sequence at intervals.
[0066] In this embodiment, the humidity control valve 400 is fixed to the rear cover 200, which can reduce the seepage of water from the external environment into the receiving cavity 600 through the installation gap between the humidity control valve 400 and the rear cover 200. The humidity control valve 400, the camera assembly 300, and the first side plate 110 are arranged sequentially at intervals, so that the setting of the humidity control valve 400 will not affect the arrangement of the camera assembly 300, which is conducive to the orderly arrangement of the vision assembly 20.
[0067] Figure 5 This is a schematic diagram of a housing 100 provided in an embodiment of this application.
[0068] In one embodiment, such as Figure 3 and Figure 5 As shown, the housing 100 includes an opening 130, which encloses the rear cover 200 and the housing 100 to form a receiving cavity 600. A dehumidifying plate 500 is fixed to the side wall 120 of the housing 100. Along the first direction Y, the humidity control valve 400, the dehumidifying plate 500, and the camera assembly 300 are arranged at intervals. Along the first direction Y, the distance between the dehumidifying plate 500 and the opening 130 is less than the distance between the dehumidifying plate 500 and the camera assembly 300.
[0069] In this embodiment, the dehumidifier 500 is fixed to the side wall 120 of the housing 100. The humidity control valve 400, the dehumidifier 500 and the camera assembly 300 are arranged at intervals along the first direction Y, so that the water vapor entering the receiving cavity 600 through the humidity control valve 400 can be dehumidified by the dehumidifier 500 before contacting the camera assembly 300, thereby reducing the probability of condensation on the camera assembly 300.
[0070] In this embodiment, along the first direction Y, the distance between the dehumidifying plate 500 and the opening 130 is less than the distance between the dehumidifying plate 500 and the camera assembly 300. This allows the dehumidifying plate 500 to be positioned closer to the opening 130 of the housing 100, thereby enabling water that seeps into the receiving cavity 600 from the gap between the rear cover 200 and the housing 100 to be absorbed by the dehumidifying plate 500 more quickly. This reduces the humidity inside the receiving cavity 600, thereby reducing the probability of condensation on the camera assembly 300 and extending the service life and operational safety of the vision assembly 20.
[0071] In one embodiment, a sealing ring is provided at the opening 130 of the housing 100, the sealing ring being used to seal the receiving cavity 600.
[0072] Figure 6 This is a schematic diagram of the structure of the back cover 200 provided in the embodiment of this application.
[0073] In one embodiment, such as Figure 4 and Figure 6As shown, the dehumidifier 500 is fixed to the inner wall of the rear cover 200 and close to the opening 130, and the dehumidifier 500 is spaced apart from the humidity control valve 400.
[0074] In this embodiment, the dehumidifier 500 is fixed to the inner wall of the rear cover 200. If the moisture absorbed by the dehumidifier 500 cannot be discharged from the vision component 20 due to the increase in temperature within the receiving cavity 600, resulting in a decrease in the water absorption capacity of the dehumidifier 500, replacing the dehumidifier 500 only requires opening the rear cover 200, making the operation simple. The dehumidifier 500 is spaced apart from the humidity control valve 400, ensuring that the dehumidifier 500 does not affect the ventilation of the humidity control valve 400, allowing the humidity control valve 400 to promptly balance the pressure difference between the receiving cavity 600 of the vision component 20 and the external environment.
[0075] In this embodiment, placing the dehumidifying plate 500 closer to the opening 130 of the housing 100 allows water seeping into the housing 100 from the opening 130 to be absorbed by the dehumidifying plate 500 more quickly, reducing the humidity in the receiving cavity 600. This helps to reduce the probability of condensation on the camera component 300, extend the service life of the vision component 20, and improve its operational safety.
[0076] Figure 7 This is another exploded view of the visual component 20 provided in the embodiments of this application.
[0077] In one embodiment, such as Figure 7 As shown, the dehumidifying plate 500 surrounds the humidity control valve 400, and the dehumidifying plate 500 is positioned near the opening 130 of the housing 100.
[0078] In this embodiment, the dehumidifying plate 500 surrounds the humidity control valve 400, so that the moisture entering the receiving cavity 600 through the humidity control valve 400 can be quickly absorbed by the dehumidifying plate 500 surrounding the periphery. It can also absorb water seeping in from the installation gap between the humidity control valve 400 and the rear cover 200 in a timely manner, reduce the humidity in the receiving cavity 600, reduce the probability of condensation on the camera component 300, and facilitate the normal operation of the vision component 20.
[0079] In this embodiment, the dehumidifier 500 is arranged close to the opening 130 of the housing 100, which allows water that seeps into the housing 100 through the opening 130 to be absorbed by the dehumidifier 500 more quickly, reducing the humidity in the receiving cavity 600. This helps to reduce the probability of condensation on the camera component 300, extend the service life of the vision component 20 and improve its operational safety.
[0080] Figure 8 This is another schematic diagram of the visual component 20 provided in the embodiments of this application.
[0081] In one embodiment, such as Figure 5 and Figure 8 As shown, the humidity control valve 400 is fixed to the side wall 120 of the housing 100, and the rear cover 200, the humidity control valve 400, and the camera assembly 300 are arranged at intervals along the first direction Y.
[0082] In this embodiment, the humidity control valve 400 is fixed to the side wall 120 of the housing 100, so that the arrangement of the humidity control valve 400 will not affect the arrangement of the camera assembly 300 on the first side plate 110, and it is also convenient for the humidity control valve 400 to be installed and removed directly from the other side wall 120 of the housing 100.
[0083] In this embodiment, the rear cover 200, the humidity control valve 400, and the camera assembly 300 are arranged at intervals along the first direction Y, so that the arrangement of the humidity control valve 400 and the camera assembly 300 will not interfere with each other, and the device arrangement in the receiving cavity 600 of the vision assembly 20 is reasonable and orderly.
[0084] In one embodiment, such as Figure 5 and Figure 8 As shown, the dehumidifying plate 500 is fixed to the side wall 120 of the housing 100 or the rear cover 200. The rear cover 200, the dehumidifying plate 500 and the camera assembly 300 are arranged at intervals along the first direction Y.
[0085] In this embodiment, the dehumidifier 500 absorbs moisture from the cavity 600. The rear cover 200, the dehumidifier 500, and the camera assembly 300 are arranged at intervals along the first direction Y, so that there is a certain distance between the dehumidifier 500 and the camera assembly 300. This prevents the moisture released by the dehumidifier 500 due to temperature rise from quickly condensing on the camera assembly 300, reducing the probability of condensation on the camera assembly 300 and ensuring the normal operation of the vision assembly 20.
[0086] In one embodiment, such as Figure 5 and Figure 8 As shown, the dehumidifier 500, the humidity control valve 400, and the camera assembly 300 are arranged at intervals along the first direction Y. Along the first direction Y, the distance between the dehumidifier 500 and the opening 130 is less than the distance between the dehumidifier 500 and the humidity control valve 400.
[0087] In this embodiment, the dehumidifier 500, the humidity control valve 400, and the camera assembly 300 are arranged at intervals along the first direction Y, so that the dehumidifier 500 can not only quickly absorb the water vapor that enters the receiving cavity 600 through the humidity control valve 400, but also quickly absorb the water from the external environment that seeps in from the opening 130 of the housing 100, thereby reducing the humidity in the receiving cavity 600 and thus helping to reduce the probability of condensation on the camera assembly 300.
[0088] In this embodiment, along the first direction Y, the distance between the dehumidifying plate 500 and the opening 130 is less than the distance between the dehumidifying plate 500 and the humidity control valve 400, so that the dehumidifying plate 500 is arranged closer to the opening 130, which is conducive to the dehumidifying plate 500 absorbing water that seeps into the receiving cavity 600 from the opening 130 of the housing 100 more quickly, thereby helping to reduce the humidity in the receiving cavity 600 and reduce the probability of condensation in the camera component 300.
[0089] Figure 9 This is another schematic diagram of the visual component 20 provided in the embodiments of this application.
[0090] In one embodiment, such as Figure 4 and Figure 9 As shown, the housing 100 also includes a first protrusion 140, which protrudes from the opening 130 away from the first side plate 110 along the first direction Y. The first protrusion 140 is used to fix the housing 10 of the lawnmower 1. The distance between the end of the first protrusion 140 away from the first side plate 110 and the opening 130 along the first direction Y is greater than the distance between the end of the humidity control valve 400 away from the first side plate 110 and the opening 130.
[0091] In this embodiment of the application, the first protrusion 140 protrudes from the opening 130 away from the first side plate 110 along the first direction Y, so that the vision component 20 can be fixed to the housing 10 of the lawnmower 1 behind the camera component 300 along the first direction Y, and the camera component 300 can always be kept in front of the lawnmower 1 in the direction of movement.
[0092] In the embodiments of this application, such as Figure 9 As shown, the distance between the end of the first protrusion 140 facing away from the first side plate 110 and the opening 130 along the first direction Y is denoted as L1, and the distance between the end of the humidity control valve 400 facing away from the first side plate 110 and the opening 130 is denoted as L2. L1 > L2, which creates a gap between the humidity control valve 400 and the housing 10, allowing the humidity control valve 400 to ventilate with the external environment to balance the pressure between the receiving cavity 600 and the external environment. L1 > L2 also allows the first protrusion 140 to shield the humidity control valve 400 in the height direction of the lawnmower 1, thereby reducing the amount of water flowing into the receiving cavity 600 from above the lawnmower 1 through the installation gap between the humidity control valve 400 and the rear cover 200. This helps maintain a dry environment inside the receiving cavity 600, reduces camera fogging, and facilitates the normal operation of the vision component 20.
[0093] In one embodiment, such as Figure 5 and Figure 8As shown, the sidewall 120 of the housing 100 includes a second protrusion 121, which protrudes away from the receiving cavity 600. The length direction A of the second protrusion 121 intersects with the first direction Y. The housing 100 also includes a top plate 150 and a bottom plate 160, which are arranged opposite each other along the second direction Z. The second direction Z is perpendicular to the first direction Y. Along the second direction Z, the bottom plate 160, the humidity control valve 400, and the second protrusion 121 are arranged in sequence.
[0094] In this embodiment, the second protrusion 121 is raised away from the receiving cavity 600. The length direction A of the second protrusion 121 intersects with the first direction Y, so that the second protrusion 121 can be arranged obliquely on the other side wall 120 of the housing 100, which is beneficial to drain the water falling on the top plate 150 of the lawnmower 1 and reduce the water accumulation on the housing 100 of the vision component 20.
[0095] In this embodiment, along the second direction Z, the base plate 160, the humidity control valve 400, and the second protrusion 121 are arranged in sequence, so that the second protrusion 121 along the second direction Z can shield the humidity control valve 400, thereby reducing the amount of water on the top plate 150 of the lawnmower 1 flowing into the receiving cavity 600 through the installation gap between the humidity control valve 400 and the other side walls 120 of the housing 100. This helps to maintain a dry environment in the receiving cavity 600, reduces the probability of condensation on the camera component 300, and facilitates the normal operation of the vision component 20.
[0096] Figure 10 This is a schematic diagram of a humidity control valve 400 provided in an embodiment of this application.
[0097] In one embodiment, such as Figure 7 , Figure 8 and Figure 10 As shown, one of the side wall 120 and the rear cover 200 of the housing 100 includes a first opening 201. The humidity control valve 400 includes a pressure control member 410 and a vent 420 connected to each other. The vent 420 passes through the first opening 201. The pressure control member 410 is located on the inner side of one of the side wall 120 and the rear cover 200 of the housing 100 facing the receiving cavity 600.
[0098] In this embodiment of the application, one of the side wall 120 and the rear cover 200 of the housing 100 includes a first opening 201, so that the humidity control valve 400 can be installed and fixed on the side wall 120 or the rear cover 200 of the housing 100.
[0099] In this embodiment, the vent 420 passes through the first opening 201, allowing the vent 420 to connect the receiving cavity 600 to the external environment, enabling the humidity control valve 400 to balance the pressure difference between the receiving cavity 600 and the external environment. The pressure control member 410 is located on the inner side facing the receiving cavity 600, allowing the pressure control member 410 to contact the gas inside the receiving cavity 600. The cooperation between the pressure control member 410 and the vent 420 allows gas to be discharged from the receiving cavity 600 when the air pressure inside the receiving cavity 600 is higher than that of the external environment, and also allows outside air to be introduced into the receiving cavity 600 when the air pressure inside the receiving cavity 600 is lower than that of the external environment, thus balancing the pressure difference between the receiving cavity 600 and the external environment.
[0100] In one embodiment, such as Figure 7 and Figure 10 As shown, the humidity control valve 400 also includes a connecting part 430, which is used to fix the pressure control member 410 to the venting part 420. The connecting part 430 protrudes from the venting part 420 toward the receiving cavity 600.
[0101] In one embodiment, such as Figure 7 , Figure 8 and Figure 10 As shown, one of the sidewall 120 of the housing 100 and the rear cover 200 also includes a first groove 202. The opening of the first groove 202 faces away from the receiving cavity 600. The first opening 201 penetrates the bottom of the first groove 202. The vent 420 includes a mounting surface 421, which is fixed to the bottom of the first groove 202.
[0102] In this embodiment, the opening of the first groove 202 faces away from the receiving cavity 600, making the installation of the vent 420 of the humidity control valve 400 in the first groove 202 smoother. The first opening 201 penetrates the bottom of the first groove 202. The vent 420 includes a mounting surface 421, which is fixed to the bottom of the first groove 202. This allows the vent 420 to not only pass through the first opening 201 into one of the side wall 120 and the rear cover 200 of the housing 100, but also to be fixed to one of the side wall 120 and the rear cover 200 of the housing 100 through the first groove 202. This makes the vent 420 of the humidity control valve 400 more securely fixed, thereby helping to ensure the normal operation of the humidity control valve 400 and balance the pressure difference between the receiving cavity 600 and the external environment.
[0103] In one embodiment, the ratio of the volume of the dehumidifying plate 500 to the volume of the receiving cavity 600 is greater than or equal to 1:2000 and less than or equal to 1:200.
[0104] In this embodiment, the volume of the dehumidifier 500 is sufficient to meet the dewatering requirements of the receiving cavity 600, and it does not occupy too much space in the receiving cavity 600.
[0105] In one embodiment, such as Figure 7 and Figure 10 As shown, the humidity control valve 400 also includes a pressure control element 410, a venting portion 420, and a waterproof and breathable membrane. The waterproof and breathable membrane is disposed on the side of the venting portion 420 facing away from the receiving cavity 600, and the pressure control element 410 is disposed on the side of the venting portion 420 facing the receiving cavity 600. The waterproof and breathable membrane, the venting portion 420, the pressure control element 410, and the camera assembly 300 are spaced apart.
[0106] In this embodiment, the waterproof and breathable membrane can reduce the humidity of the moisture in the external environment that the humidity control valve 400 introduces into the receiving cavity 600, thereby reducing the intake of moisture and reducing the moisture in the receiving cavity 600.
[0107] In one embodiment, the vent 420 and the connecting portion 430 include vent holes for communicating with the external environment and the receiving cavity 600. The pressure control component 410 includes a mounting hole, an air inlet, and an air outlet. The mounting hole is connected to the vent holes, and the connecting portion 430 is inserted into the mounting hole. The air inlet includes a first valve flap for closing or opening the mounting hole. The air outlet is provided with an air outlet and at least one second valve flap. The air outlet communicates with the vent holes, and each second valve flap is disposed on the inner surface of the air outlet, for opening or closing the air outlet.
[0108] In one embodiment, the humidity control valve 400 further includes a pressure cap with a venting groove. The venting groove is disposed opposite to the vent hole, and the pressure cap is fixedly connected to the side of the vent 420 away from the receiving cavity 600.
[0109] In one embodiment, under normal operating conditions, i.e., when the air pressure in the receiving cavity 600 is the same as that in the external environment, the mounting hole and the vent are normally closed, effectively preventing moisture from entering and providing a dry working environment for the camera component 300 inside the receiving cavity 600, thereby helping to extend the service life of the camera component 300. When the air pressure in the receiving cavity 600 is greater than the external air pressure, the second valve disc deforms under the pressure of the air pressure, opening the vent channel, allowing the gas inside the cavity to flow out and releasing pressure to balance the pressure difference between the receiving cavity 600 and the external environment. When the air pressure in the receiving cavity 600 is less than the external environment air pressure, the first valve disc deforms, opening the mounting hole channel, allowing external gas to enter the receiving cavity 600, balancing the internal and external pressure difference between the receiving cavity 600 and the external environment.
[0110] In one embodiment, when the pressure difference between the accommodating cavity 600 and the external environment is 2-4 kPa, the humidity control valve 400 opens the air outlet or installation channel.
[0111] In one embodiment, the humidity control valve 400 will open the installation channel when the pressure difference between the containment cavity 600 and the external environment reaches a preset threshold, allowing external air to enter the containment cavity 600. This reduces the frequency of external air entering, thereby reducing the entry of moisture and helping to keep the containment cavity 600 dry, thus reducing the probability of condensation on the camera component 300.
