Description

Technical Field

[0001] This utility model relates to the field of garden tools technology, and in particular to a lawnmower. Background Technology

[0002] A lawnmower is a device used to mow lawns in yards, gardens, and large lawns. Current smart lawnmowers, which use vision sensors or cameras, generate heat during operation due to sensor activity. A common cooling method is to expose the sensors directly to the outside air, relying on natural airflow for heat dissipation. However, in hot environments, exposed sensors also absorb radiant heat from the sun, reducing overall heat dissipation efficiency, affecting the lawnmower's continuous operation, and even causing overheating and shutdown. Furthermore, some products use fans; however, introducing fans not only requires internal space, increasing the device's size and weight, but also incurs additional manufacturing costs and energy consumption. Summary of the Invention

[0022] See Figure 1 Figure 1 shows an exploded structural diagram of an intelligent lawnmower according to an embodiment of the present invention. The intelligent lawnmower provided in an embodiment of the present invention includes a main body 10, a walking component 20, a mowing component 22, and a power supply component 30.

[0023] The main body 10 further includes an outer shell 11 and a bottom shell 12 arranged vertically, the outer shell 11 and the bottom shell 12 being connected to each other to form a receiving space. A walking assembly 20 is disposed on the main body 10 and is used to drive the main body 10 to move. The walking assembly 20 further includes walking wheels 21 and a drive motor. In some embodiments, the walking wheels 21 include drive wheels 211 and steering wheels 212. The power supply assembly 30 is disposed within the receiving space of the main body 10 and includes a battery compartment 31 and a battery pack 32, used to supply power to the walking assembly 20 and the lawnmower assembly 22, etc.

[0024] Combination Figures 2 to 3 As shown, the intelligent lawnmower further includes: a camera assembly 13, a vision processing module 14, and a heat sink 15, which are respectively disposed within the accommodating space of the main body 10.

[0025] The camera assembly 13 is used to collect visual information around the lawnmower; the vision processing module 14 is used to receive and process the visual information. A heat sink 15, in contact with the vision processing module 14, is used to dissipate heat from the vision processing module 14 to reduce its temperature and ensure normal operation. Specifically, the heat sink 15 is made of metal; in some embodiments, it is made of aluminum or copper. The heat sink 15 includes a base 151 and a heat dissipation column 152. The base 151 has a contact surface that contacts the vision processing module 14; the heat dissipation column 152 is located on the side of the base 151 opposite to the vision processing module 14, corresponding to the contact surface. The heat dissipation column 152 extends downwards along the vertical direction of the smart lawnmower until it contacts the bottom shell 12. Correspondingly, the bottom shell 12 has an opening 121, allowing the heat dissipation column 152 to contact the air, thus better conducting heat to the outside and reducing the temperature of the vision processing module 14. Furthermore, the heat dissipation column 152 has a hollow structure with a hollow channel 1521. One end of the channel is the base 151 of the heat sink 15, and the other end of the channel is connected to the opening 121 on the bottom shell 12. The air flowing through the hollow channel 1521 continuously exchanges heat with the base 151 to achieve the purpose of heat dissipation.

[0026] In some real-time examples, the heat sink 15 also includes heat dissipation fins 153, which are fixedly connected to the base 151, positioned corresponding to the contact surface and located on the side of the base 151 opposite to the vision processing module 14. Multiple heat dissipation fins 153 are arranged at intervals, which helps to increase the heat dissipation area and improve the heat dissipation effect. Some heat dissipation fins 153 are located within the hollow channel 1521, which can also improve the heat exchange efficiency within the hollow channel 1521.

[0027] In some embodiments, an elastic element 154 is provided between the heat dissipation column 152 and the bottom shell 12 for sealing. Specifically, the elastic element 154 is a silicone pad, thereby sealing the accommodating space. In addition, a thermally conductive silicone 155 is provided between the base 151 and the vision processing module 14. The thermally conductive silicone 155 has good thermal conductivity and can improve thermal conductivity efficiency.

[0028] Combination Figure 4 As shown, Figure 4A three-dimensional structural diagram of an intelligent lawnmower according to an embodiment of this application is shown (the outer shell 11 is omitted in the figure). In some embodiments, the intelligent lawnmower also includes a middle shell 16, which divides the accommodating space into a first space and a second space arranged vertically. The middle shell 16 is snapped into the bottom shell 12 to form the first space, which houses the vision processing module 14, the drive motor 22, and the power supply component 30, etc.; the middle shell 16 is snapped into the outer shell 11 to form the second space, which houses the camera component 13, etc. In this way, the middle shell 16 divides the accommodating space into two, which serves as an isolation layer, preventing moisture from entering the first space and improving the airtightness of the first space.

[0029] In some embodiments, to further improve the airtightness of the first space, the middle shell 16 includes a first surface 161 and a drainage channel. The first surface 161 is an inclined surface that is higher at the rear and lower at the front along the front-rear direction of the lawnmower. The drainage channel is disposed on the first surface 161 and extends from the rear to the front. A downstream drain outlet 163 is provided at the front end of the lawnmower. Optionally, there may be one or two first drain outlets. In some embodiments, an upstream drain outlet 164 is also provided at each of the left and right ends of the first surface 161. In this way, liquid entering the second space can be discharged through the drainage channel from the first drain outlet 163 and / or the second drain outlet 164 without seeping into the first space, thereby improving the airtightness of the first space.

[0030] In addition, one or more mounting bases for mounting electronic components are provided on the first surface 161. The mounting bases are surrounded by sidewalls protruding from the first plane, which can prevent water from entering the mounting bases and thus avoid short circuits in the electronic components due to water stains. Specifically, the electronic components can be display components used to display the status of the lawnmower, battery level, etc.

[0031] In some embodiments, a lighting module 165 is disposed on the first surface 161, comprising: a base 1651 mounted on the first surface 161; a lampshade 1652; and an LED light (not shown) housed within the space formed by the base and the lampshade. If the light is turned on at night, it may attract phototactic insects into the lampshade. To prevent this and enhance the airtightness of the lampshade, the lighting module further includes sealing cotton 1653, disposed between the contact surfaces of the lampshade and the base, thereby filling the gap between the base and the lampshade to prevent insects from entering the lampshade through this gap.

[0032] In some embodiments, the presence of a second drain outlet 164 on the middle shell 16 allows insects to enter the second space between the outer shell 11 and the middle shell 16. Therefore, to prevent insects from entering the lawnmower, an insect-proof structure 166 is provided at the second drain outlet 164 to prevent insects from entering the machine through the upstream drain outlet. Specifically, the insect-proof structure 166 consists of two layers of staggered baffles arranged at the upstream drain outlet. The gaps between the baffles allow water to flow through while preventing insects from entering, thereby preventing insects from entering the machine.

[0033] Combination Figure 5 As shown in Figure 5, an exploded view of the camera assembly 13 provided in one embodiment of this application is presented. In some embodiments, the camera assembly 13 is mounted on a mounting base of the middle shell 16. The camera assembly 13 includes a camera 131, a housing 132, and a front cover 133. The front cover 133 and the housing 132 are connected to form a receiving cavity. The front cover has a shooting window that allows the camera to be exposed for shooting. To protect the camera from moisture, dust, etc., the camera assembly 13 also includes a first elastic sealing ring 134 and a second elastic sealing ring 135. The first elastic sealing ring 134 is disposed between the front cover 133 and the housing 132 to seal the gap between the front cover 133 and the housing 132.

[0034] In some embodiments, the housing 132 further includes a first housing 1321 and a second housing 1322. The first housing 1321 and the second housing 1322 can be assembled from left and right sides to form the housing 132. In order to prevent gaps between the first housing 1321 and the second housing 1322, a sealing strip 136 is provided between the first housing 1321 and the second housing 1322 to seal the gap between the first housing 1321 and the second housing 1322, so as to prevent external moisture and dust and other debris from entering the gap and contaminating the camera.

[0035] In addition, combined Figure 2 As shown, the intelligent lawnmower also includes an RTK antenna 17, used to receive signals from navigation satellites to locate the intelligent lawnmower. To ensure accurate signal reception, the RTK antenna 17 is positioned at the center above the steering wheel 212 on the front side of the second space of the main body 10, reducing the influence of surrounding structures on the signal. Because the intelligent lawnmower has a compact structure and the various electronic modules are close together, which could affect signal stability, the RTK antenna 17 is positioned at a distance of at least 30 mm from the camera 131 and at least 40 mm from the vision processing module 14. This reduces interference and influence from other modules on the signal reception of the RTK antenna 17, improving its stability.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
