[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.
[0022] In a first embodiment of this utility model, an intelligent lawnmower is provided, including an optical detection device 1, a body 2, a decorative cover 3, a blower 4, an opening 201, and a guide section. The body 2 has a mounting base 21 for mounting the optical detection device 1. The decorative cover 3 is connected to the mounting base 21 and / or the body 2, and together with the mounting base 21, forms a mounting cavity for accommodating the optical detection device 1. The decorative cover 3 has an opening for the probe portion 11 of the optical detection device 1 to extend out. The blower 4 is used to blow air onto the surface of the probe portion 11. Preferably, the blower 4 is disposed within the mounting cavity. The opening 201 is disposed on the body 2 and / or the mounting base 21, and the opening 201 connects the mounting cavity and the external space. The opening 201 is configured as a handle for gripping the intelligent lawnmower. The guide section is disposed within the mounting cavity and connects to the opening 201. The guide section forms a liquid flow path connecting the opening on the decorative cover 3 and the opening 201.
[0023] In the above embodiment, the blowing device 4 installed in the mounting cavity generates airflow when the optical detection device 1 is working and blows it onto the surface of the probe part 11. This prevents the optical detection device 1 from being interfered with by grass clippings, dust, and other debris during operation, avoiding misjudgments caused by grass clippings and dust obscuring the optical detection device 1 during operation, thus preventing the entire machine from malfunctioning. Furthermore, through the opening 201 provided on the body 2 and / or mounting base 21, air can enter from the opening 201 on the rear side of the intelligent lawnmower and then be blown out from the probe part 11 of the optical detection device 1 via the blowing device 4. The mounting cavity not only serves as an independent chamber for installing the optical detection device 1 and the blowing device 4, but also as an air duct 400 for air intake. On one hand, it provides an air source for the blowing device 4; on the other hand, it serves as a heat dissipation air duct 400 for cooling the blowing device 4 and other electronic components inside the body 2. This eliminates the need for an additional cooling fan, thereby simplifying the structure, reducing the complexity, size, and power consumption of the entire machine, and facilitating cost reduction and product miniaturization. Furthermore, the opening 201 can also serve as a handle, making it convenient to grab the smart lawnmower and move it around.
[0024] Furthermore, the opening 201 also serves as a drainage structure, draining accumulated water from inside the machine body 2. Through the provided guide section, rainwater entering the mounting cavity from the opening is guided to the opening 201 and promptly discharged, preventing rainwater accumulation inside the machine and its impact on normal operation and lifespan. The guide section and opening 201 not only directly guide and discharge liquid to the outside of the machine body 2, achieving drainage from the outer side, but also, during outdoor operation, sunlight heats the machine body 2, further promoting internal moisture evaporation. This moisture can also be discharged through the guide section and opening 201, effectively preventing damage to electronic components from accumulated water and humidity. In this application, the opening 201 serves multiple purposes—air intake, drainage, and a handle—making it more versatile and functional.
[0025] Based on the above embodiments, as a further defined embodiment, the opening area of the opening 201 is larger than the set area. By setting the opening area of the opening 201 to be larger, not only can the heat dissipation efficiency be improved, but it can also serve as a handle for easy lifting, transfer, and handling by the staff. Preferably, the length of the opening 201 is greater than four fingers and the width is greater than one finger, so that the staff can insert four fingers into the opening 201 to lift and transfer the smart lawnmower, making operation convenient.
[0026] Based on the above embodiments, as a further defined embodiment, the optical detection device 1 includes, but is not limited to, lasers and panoramic cameras. Preferably, the optical detection device 1 is a radar, and more preferably, it is a lidar. The mounting base 21 is integrally formed with the body 2. The mounting base 21 has a mounting groove with a top opening. The decorative cover 3 is a cover structure, covering the optical detection device 1. The decorative cover is detachably connected to the mounting base 21 and / or the body 2. Optionally, the decorative cover is snap-fitted to the mounting base 21. The optical detection device 1 includes a main body and a probe part 11 disposed on the top of the main body. Preferably, the main body is columnar, and the probe part 11 is hemispherical. The top of the decorative cover 3 has an opening for the probe part 11 of the optical detection device 1 to extend out. The main body is located inside the mounting cavity, and the probe part 11 is located outside the mounting cavity, extending out of the body 2.
[0027] In one optional embodiment, the blower 4 includes an airflow drive 41 and an air duct 400. The airflow drive 41 is disposed within the mounting cavity. The air duct 400 has an air duct inlet 401 and an air duct outlet 402. The air duct outlet 402 surrounds the outer periphery of the probe portion 11 and communicates with an opening. The airflow drive 41 is disposed at the air duct inlet 401 and is adapted to drive airflow from the air duct inlet 401 into the air duct 400 and blow it onto the surface of the probe portion 11 through the air duct outlet 402. A drain outlet 403 is provided on the bottom wall of the air duct 400. The guide portion includes a first drainage channel connecting the air duct outlet 402 and the drain outlet 403. The first drainage channel is formed by at least a portion of the air duct 400.
[0028] In the above embodiment, the air duct 400 directs the airflow generated by the airflow drive 41 to the surface of the probe portion 11. Furthermore, the design of the air duct outlet 402 surrounding the probe portion 11 allows the airflow from the outlet 402 to blow across the entire surface of the probe portion 11, creating a 360° airflow with no blind spots and better protection against obstructions. The drain outlet 403 on the bottom wall of the air duct 400 and the first drainage channel formed within the air duct 400 allow rainwater and debris entering the air duct 400 from the outlet 402 to flow out of the air duct 400 along the first drainage channel, preventing debris and rainwater from accumulating inside the air duct 400 and affecting the overall lifespan of the device.
[0029] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 includes, but is not limited to, a fan, blower, impeller, blower, and air compressor. The air outlet of the airflow drive component 41 is sealed and connected to the air duct inlet 401. The air duct outlet 402 can be an integral annular opening, or it can be a plurality of openings 201 spaced apart circumferentially along the probe portion 11. Preferably, the air duct outlet 402 is an integral annular opening.
[0030] In one alternative embodiment, the flow guide further includes a first flow guide surface, wherein the bottom wall of the air duct 400 slopes downward toward the drain outlet 403 to form the first flow guide surface. By constructing the bottom wall of the air duct 400 as a first flow guide surface that slopes downward toward the drain outlet 403, a flow guide function can be achieved, allowing the accumulated water entering the air duct 400 to be discharged more thoroughly and improving the water discharge efficiency.
[0031] Based on the above embodiments, as a further defined embodiment, along the traveling direction of the intelligent lawnmower, the intelligent lawnmower has a windward side and a leeward side, with the opening 201 located on the leeward side; the drain outlet 403 is located on the bottom wall of the air duct 400 near the leeward side, and the bottom wall of the air duct 400 gradually slopes downward from the windward side to the leeward side. An air inlet 301 is provided on the decorative cover 3 located on the windward side, and an opening 201 is provided on the mounting base 21 located on the leeward side. Both the air inlet 301 and the opening 201 connect the mounting cavity and the external space. In the above embodiment, by placing the opening 201 on the leeward side of the smart lawnmower, the user cannot see the opening 201 from the front, thus improving the aesthetics of the smart lawnmower. By placing the drain outlet 403 on the bottom wall of the air duct 400 near the leeward side, and by setting the bottom wall of the air duct 400 to gradually slope downward from the windward side to the leeward side, rainwater and debris entering the air duct 400 are directed as far as possible towards the drain outlet 403 on the leeward side, and then discharged to the outside of the machine through the opening 201 on the leeward side, preventing them from flowing towards the airflow drive component 41. Furthermore, the air inlet 301 provided on the decorative cover 3 on the windward side can further increase the air intake volume.
[0032] In an optional embodiment, the guide portion further includes a second drainage channel communicating between the drain outlet 403 and the opening 201, the second drainage channel being formed by a portion of the inner cavity of the mounting base 21. Through the aforementioned second drainage channel, accumulated water can be drained from the drain outlet 403 into the mounting cavity, then directed along the second drainage channel to the opening 201, and finally discharged from the opening 201 into the external environment.
[0033] In one optional embodiment, the mounting base 21 includes a leeward sidewall located on the leeward side; the opening 201 is a notch structure provided on the leeward sidewall, and the notch structure penetrates the top and bottom surfaces of the leeward sidewall. The guide portion includes a second guide surface, and the bottom wall of the mounting base 21 is inclined downward toward the opening 201 to form the second guide surface.
[0034] In the above embodiment, the opening 201, with its notch structure design, is easy to manufacture and can also serve as a handle, making it convenient for users to move and transport the smart lawnmower. Furthermore, by setting the notch structure to penetrate the top and bottom surfaces of the leeward sidewall, the bottom edge of the opening 201 extends to the bottom wall of the mounting cavity. When rainwater enters the mounting cavity, it can drain directly through the opening 201 without being blocked by its bottom edge, resulting in more efficient and thorough drainage. Moreover, by constructing the bottom wall of the mounting base 21 as a second guide surface that slopes downwards towards the opening 201, the efficiency of water drainage can be further improved, preventing rainwater from accumulating inside the mounting cavity.
[0035] Based on the above embodiments, as a further defined embodiment, the leeward sidewall constitutes the rear wall of the body 2. Along the length direction of the leeward sidewall, a notch is provided in the middle part of the leeward sidewall to form an opening 201. The shape of the opening 201 is adapted to the shape of the bottom wall of the mounting base 21. The bottom edge of the opening 201 is at the same horizontal plane as the bottom wall of the mounting base 21, and will not obstruct the mounting cavity. The length of the notch structure is greater than half the length of the leeward sidewall. Preferably, the length of the notch structure is greater than four fingers, and the width of the notch structure is the same as the height of the leeward sidewall.
[0036] In one alternative embodiment, the air inlet side of the decorative cover 3 is provided with an air inlet area; the air inlet area is provided with a plurality of grilles at intervals, and the gaps between the grilles form an air inlet 301.
[0037] In the above embodiment, by setting a grille and using the grille gap as an air inlet 301, foreign objects can be blocked, preventing large impurities from entering the installation cavity from the air inlet 301.
[0038] Based on the above embodiments, as a further defined embodiment, the grille and the decorative cover 3 are integrally formed, and the grille is an arc shape that is recessed into the mounting cavity.
[0039] In one alternative embodiment, the bottom wall of the air duct 400 is provided with a drain hole 404 on the side near the windward side.
[0040] In the above embodiment, by providing a drainage hole 404 on the windward side of the air duct 400, debris and rainwater entering the air duct 400 can be quickly discharged to the outside through the drainage hole 404 and the drain outlet 403, thereby further improving the drainage efficiency of the air duct 400 and avoiding the problem that the water in the air duct 400 cannot be discharged in time when the amount of rainwater is too large or too fast, which may cause related safety hazards.
[0041] In one optional embodiment, the air duct inlet 401 is located on the bottom wall of the air duct 400 and on the side closer to the windward side; a baffle 421 is also provided on the bottom wall of the air duct 400, and the baffle 421 is disposed between the air duct inlet 401 and the drain hole 404. In the above embodiment, by setting the air duct inlet 401 on the side close to the windward side, it is convenient to install the airflow drive component 41 on the side close to the air inlet 301. Furthermore, by setting the baffle 421 between the air duct inlet 401 and the drain hole 404, it is convenient for the accumulated impurities to flow along the baffle 421 to the drain hole 404 and be discharged. In addition, the baffle 421 can also guide the airflow, so that the air entering from the air duct inlet 401 can be directed to the air duct outlet 402, avoiding the phenomenon that the air entering from the air duct inlet 401 is directly discharged from the drain hole 404.
[0042] Based on the above embodiments, as a further defined embodiment, the drain hole 404 is correspondingly located below the air duct outlet 402, the air duct inlet 401 is located on the side of the drain hole 404 away from the optical detection device 1, and the air duct inlet 401 is away from the air duct outlet 402. This design allows rainwater, impurities and other accumulated materials entering from the air duct outlet 402 to flow directly downwards and be discharged from the drain hole 404.
[0043] Based on the above implementation method, as a further defined implementation method, the side wall of the baffle 421 near the air duct inlet 401 is an inclined air guide surface, which can guide the air upward and blow it out from the air duct outlet 402.
[0044] Based on the above embodiments, as a further defined embodiment, the blower 4 also includes a filter screen, which is disposed between the air duct inlet 401 and the air duct outlet 402. The filter screen can intercept impurities and effectively prevent impurities entering from the air duct inlet 401 from flowing to the airflow drive component 41 and causing related safety hazards.
[0045] Based on the above embodiments, as a further defined embodiment, the filter screen is disposed in the air duct 400 near the windward side. Preferably, the filter screen is installed on the baffle 421, which has an L-shaped mounting body with a longitudinal cross section. The bottom of the filter screen is supported and installed in the mounting groove formed in the mounting body, which provides higher stability. The top of the filter screen extends to a position that abuts against the inner wall surface of the outer side wall of the air duct 400, which can effectively intercept foreign objects.
[0046] Based on the above embodiments, as a further defined embodiment, the filter screen and the baffle 421 are snap-fitted together for easy disassembly and secure fixation. As an alternative embodiment, the filter screen is interference-fitted between the baffle 421 and the air duct 400.
[0047] In one alternative implementation, the airflow drive 41 is waterproof; optionally, the airflow drive 41 is a waterproof fan.
[0048] In one alternative implementation, such as Figure 1 and 2 As shown, the airflow drive component 41 is disposed on the side of the mounting cavity near the windward side; the air outlet of the airflow drive component 41 is connected to the air duct inlet 401, and the air inlet of the airflow drive component 41 is connected to the mounting cavity.
[0049] In the above embodiment, the airflow drive component 41 is disposed on the side of the mounting cavity near the windward side, which facilitates the airflow drive component 41 to take in air. At the same time, the air entering the mounting cavity from the air inlet 301 of the decorative cover 3 can also pass through the airflow drive component 41 first, resulting in a better cooling and heat dissipation effect on the airflow drive component 41.
[0050] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 is a fan, and the air outlet duct inlet 401 of the airflow drive component 41 is sealed and connected.
[0051] In an alternative implementation, such as Figure 6 and Figure 7 As shown, the airflow drive 41 can also be disposed on the side of the mounting cavity near the leeward side. Alternatively, in other embodiments, the airflow drive 41 can also be disposed on the side of the smart lawnmower.
[0052] In an alternative embodiment, the blower 4 further includes a fixed bracket 43, on which the airflow drive 41 is detachably mounted, and the fixed bracket 43 is fixed to the mounting base 21.
[0053] In the above embodiment, the fixed bracket 43 facilitates the installation of the airflow drive component 41.
[0054] Based on the above embodiments, as a further defined embodiment, the airflow drive component 41 is provided with positioning holes, the fixed bracket 43 is provided with positioning ribs, and the fixed bracket 43 is also provided with buckles. During assembly, positioning is achieved by the insertion and cooperation of the positioning ribs and positioning holes, and then the airflow drive component 41 is secured by the buckles on the fixed bracket 43, so that the fixed bracket 43 and the airflow drive component 41 are fixed together, and then the two are installed together in the mounting base 21 of the body 2. Optionally, the fixed bracket 43 and the mounting base 21 are fixed with screws.
[0055] In one alternative embodiment, the air duct 400 has an annular air duct housing 42, which is fitted over the optical detection device 1; the air duct outlet 402 is an annular opening provided on the top of the air duct housing 42, and the annular air duct outlet 402 extends obliquely toward the center of the probe portion 11.
[0056] In the above embodiment, the air duct 400 adopts the design of the air duct shell 42 and is wrapped around the optical detection device 1. This not only makes the overall structure more compact, but also forms a fully enclosed surrounding air outlet effect on the outer periphery of the optical detection device 1. Moreover, the air duct outlet 402 extends obliquely towards the center of the probe part 11, so that the air coming out of the air duct outlet 402 can blow onto the entire outer surface of the probe part 11.
[0057] In one alternative embodiment, the duct housing 42 includes an inner wall, an outer wall, and a bottom wall connecting the inner wall and the outer wall; the outer wall is tapered from bottom to top, and there is an annular gap between the top edge of the outer wall and the top edge of the inner wall, the annular gap forming the duct outlet 402.
[0058] In the above embodiment, the outer wall adopts a design that gradually narrows from bottom to top, which makes the flow surface of the entire air duct 400 cavity gradually decrease from the air duct inlet 401 to the air duct outlet 402, thereby increasing the pressure at the air duct outlet 402 and increasing the air outlet speed. The air duct outlet 402 is formed by the annular gap between the top edge of the outer wall and the top edge of the inner wall of the air duct housing 42, without the need for additional openings.
[0059] Based on the above implementation method, as a further limiting implementation method, the annular gap is less than 2mm. This design can effectively prevent large impurities from entering the air duct 400.
[0060] Based on the above embodiments, as a further defined embodiment, both the inner and outer sidewalls are annular, and the top edges of the annular inner and outer sidewalls extend inclined toward the center to form an air duct outlet 402 that is inclined toward the center of the probe portion 11.
[0061] In one alternative embodiment, the outer periphery of the duct housing 42 is provided with an outward protrusion 422, the outward protrusion 422 is located on the side closer to the windward side, and the duct inlet 401 is provided on the bottom wall of the outward protrusion 422.
[0062] In the above embodiment, the external protrusion 422 is provided, and the air duct inlet 401 is provided on the bottom wall of the external protrusion 422, which facilitates the installation of the airflow drive component 41.
[0063] In one alternative embodiment, the outlet end of the air duct 400 extends between the opening of the decorative cover 3 and the probe portion 11, and is snapped and fixed to the decorative cover 3. In the above embodiment, the air duct outlet 402 extends into the gap between the opening of the decorative cover 3 and the probe part 11, which facilitates blowing air into the probe part 11. Furthermore, by snapping the outlet end of the air duct 400 to the decorative cover 3, the stability of the structure of the air duct 400 and the decorative cover 3 can be further improved.
[0064] In one alternative embodiment, the smart lawnmower also includes a radar mount 5, an optical detection device 1 detachably mounted on the radar mount 5, the radar mount 5 being fixed within the mounting base 21, and an air duct 400 detachably mounted on the radar mount 5.
[0065] In the above embodiment, the radar mounting base 5 facilitates the installation of the optical detection device 1, and the air duct 400 is detachably installed on the radar mounting base 5 so that the air duct 400, the radar mounting base 5, and the optical detection device 1 are assembled as one unit, which facilitates the overall disassembly and maintenance.
[0066] Based on the above embodiments, as a further defined embodiment, the intelligent lawnmower also includes a radar pad 6, and the optical detection device 1 is mounted on the radar mounting base 5 through the radar pad 6, which reduces wear between the optical detection device 1 and the radar mounting base 5, and at the same time can reduce vibration.
[0067] Based on the above embodiments, as a further defined embodiment, the bottom of the air duct 400 is fixed to the radar mounting base 5 by screws, and the optical detection device 1 is also fixed to the radar mounting base 5 by screws.
[0068] The specific structure, working principle, and assembly process of the intelligent lawnmower provided in this embodiment are as follows: In this embodiment, the airflow drive component 41 is fixed to the main unit via a mounting bracket 43. Simultaneously, the optical detection device 1 is fixed to the radar mounting base 5 via a radar pad 6 using four screws. The air duct housing 42 is also fixed to the radar mounting base 5 with screws, thus fixing the relative positions of the lidar and the air duct housing 42. Finally, the radar mounting base 5 is also fixed to the main unit with screws, thus fixing the relative positions of the airflow drive component 41, the air duct housing 42, and the optical detection device 1.
[0069] The specific assembly process is as follows: the airflow drive component 41 and the fixed bracket 43 are positioned through the positioning holes on the airflow drive component 41, and the fixed bracket 43 is fastened to the airflow drive component 41 with a buckle, and then they are installed together on the body 2; the optical detection device 1 and the radar pad 6 are fixed to the radar mounting base 5 with screws at the bottom, and they are fixed together on the body 2, and their relative positions with the airflow drive component 41 and the fixed bracket 43 are fixed; then the air duct housing 42 is assembled, and the air duct housing 42 is fixed to the radar mounting base 5 with screws; finally, the decorative cover 3 is assembled on the body 2 and together with the air duct housing 42 forms the air duct 400. The decorative cover 3 forms a protective cover, and the side of the decorative cover 3 covering the optical detection device 1 is provided with an air inlet 301. When the machine starts, the airflow drive 41 delivers air to the surface of the optical detection device 1 through the duct housing 42. This prevents grass clippings and dust from falling onto the lidar during operation, which could interfere with the machine's recognition and cause it to stop, thus halting the operation of the airflow drive 41. In this application, the duct housing 42 adopts a front-high-rear-low design, allowing incoming rainwater and debris to flow backward as much as possible, preventing them from flowing towards the front airflow drive 41. Simultaneously, the duct housing 42 has a drain outlet 403 at both the front and rear, allowing debris and rainwater to flow out through the leeward side opening 201, preventing their accumulation. Furthermore, a filter screen intercepts impurities, effectively preventing grass clippings and dust from falling onto the optical detection device 1 during operation and causing it to malfunction.
[0070] This application adds an independent airflow drive component 41 and an air duct 400 inside the body 2. When the optical detection device 1 is working, the airflow drive component 41 is energized to generate air, which is delivered to the surface of the optical detection device 1 through the air duct 400, so that the optical detection device 1 is not disturbed by grass clippings and dust when it is working.
[0071] In a second embodiment of this utility model, an intelligent lawnmower is provided, comprising: an optical detection device 1, a body 2, a decorative cover 3, a blower 4, an opening 201, and a flow guide. The body 2 has a mounting base 21 for mounting the optical detection device 1. The decorative cover 3 is connected to the mounting base 21 and / or the body 2, and together with the mounting base 21, forms a mounting cavity for accommodating the optical detection device 1. The decorative cover 3 has an opening for the probe portion 11 of the optical detection device 1 to extend out. The blower 4 is used to blow air onto the surface of the probe portion 11. The opening 201 is disposed on the outer side of the body 2, and the opening 201 connects the mounting cavity and the external space. The flow guide is disposed in the mounting cavity and connects to the opening 201, and the flow guide forms a liquid flow path connecting the opening on the decorative cover 3 and the opening 201.
[0072] In the above embodiments, the opening 201 provided on the outer side of the body 2 not only allows liquid to be directly guided and discharged to the outside of the body 2, thus achieving drainage from the outer side of the body 2, but also, when the lawnmower is operating outdoors, the sunlight causes the body 2 to heat up, which can further promote the evaporation of internal moisture. Water vapor can also be discharged from the guide section and the opening 201, thereby effectively avoiding damage to electronic components caused by water accumulation and moisture.
[0073] Specifically, in this embodiment, unlike the first embodiment, the opening 201 is located on the outer side of the body 2 and must be exposed, such as on the rear outer side or the left and right outer sides of the body 2.
[0074] It should be explained that, in the intelligent lawnmower provided in the second embodiment of this application, except for the position and specific setting of the opening 201, the other structures are the same as those provided in the first aspect. Other specific structures of the intelligent lawnmower in this embodiment will not be described in detail here.
[0075] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
