[0003] This utility model belongs to the field of power tool technology, specifically relating to an intelligent lawnmower. Background Technology
[0004] Lawn mowing, as a fundamental task in lawn maintenance, requires the use of simple and efficient mowing machinery to complete the task with both quality and quantity. Lawn mowers are widely popular in the market due to their ease of operation and high mowing efficiency, allowing people to complete lawn mowing tasks, trim lawns, and maintain their neatness.
[0005] Early lawnmowers on the market were walk-behind models, requiring manual pulling to control their direction and cut the grass. However, these mowers had low levels of automation and required manual intervention. With the development of intelligent technology, smart lawnmowers began to emerge and replace walk-behind models. Smart lawnmowers can automatically cut grass without human intervention, thus saving labor costs. Sensors are a crucial component of smart lawnmowers, enabling them to detect and automatically cut grass.
[0006] To further improve the intelligence of lawnmowers, current lawnmowers mostly use multiple sensors for detection, including multiple sensors for navigation, obstacle avoidance, and weather detection. Multiple sensors lead to a more complex structure and increased cost for intelligent lawnmowers.
[0007] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an intelligent lawnmower. Utility Model Content

[0116] The obstacle avoidance unit is integrated on the integrated sensing device 2 for obstacle avoidance of the intelligent mower.
[0117] The weather detection unit is integrated on the integrated sensing device 2 for weather detection.
[0118] When the integrated sensing device 2 includes at least two of the navigation unit, the obstacle avoidance unit and the weather detection unit, the intelligent mower of the present application has the corresponding functions, that is, the integrated sensing device integrates the corresponding functions, improves the functional integration of the integrated sensing device 2, simplifies the hardware structure, and also overcomes the problem of complex control system caused by using multiple external sensors in the prior art.

[0121] AsFigures 1 to 5 As shown, the intelligent lawnmower also includes a mounting plate 11 set on the support member, and the mounting plate 11 has a sensor mounting part 111, on which an integrated sensor 2 is mounted.
[0122] In this configuration, along the direction of travel of the smart lawnmower, the rear end of the sensor mounting section 111 is higher than the front end of the sensor mounting section 111, so that along the direction of travel of the smart lawnmower, the rear end of the integrated sensor 2 is higher than the front end of the integrated sensor 2, thereby forming a sensor mounting section 111 that is inclined relative to the horizontal plane along the direction of travel of the smart lawnmower, and thus ensuring that the integrated sensor 2 is also in an inclined state when it is mounted on the sensor mounting section 111.
[0123] It should be noted that the direction of travel of a smart lawnmower can be along its length, i.e. Figure 1 in the Y direction.
[0124] Specifically, the lawnmower also includes a housing 1, with the housing 1 serving as the support component. The integrated sensing device 2 is fixedly connected to the housing 1 of the smart lawnmower via a mounting plate 11, which helps to enhance the stability of the installation of the integrated sensing device.
[0125] Furthermore, such as Figure 1 As shown, in this embodiment, the tilt angle between the sensor mounting portion 111 and the horizontal plane is α, and the range of α is 10°-60°. Preferably, the tilt angle α between the sensor mounting portion 111 and the horizontal plane is 20°.
[0126] Furthermore, the tilt angle α between the sensor mounting portion 111 and the horizontal plane can be 15°, or it can be within the range of 18°, or it can be within the range of 28°. The range of the tilt angle α between the sensor mounting portion 111 and the horizontal plane is not limited to the listed values; other unlisted values within the range are also applicable.
[0127] It should be noted that the mounting plate 11 may be a convex slope, a concave slope, an irregular slope, or an inclined plane, etc. Since the integrated sensor 2 is fixedly installed on the mounting plate 11, and the integrated sensor 2 is also inclined, when the range of the tilt angle α between the sensor mounting part 111 and the horizontal plane is too small, the distance between the detection range of the integrated sensor 2 and the edge of the machine body is large, and the resulting blind spot in front is also large; when the range of the tilt angle α between the sensor mounting part 111 and the horizontal plane is too large, the integrated sensor 2 cannot detect the high places in front of the lawnmower, which is not conducive to obstacle avoidance.
[0128] Further, when the remaining parameters are determined, the inclination angle a between the sensor device mounting portion 111 and the horizontal plane in the embodiment is 20°, which can facilitate controlling the distance between the detection area of the radar body 21 and the edge of the machine to be less than or equal to 0.2 m. When the inclination angle a between the sensor device mounting portion 111 and the horizontal plane in the embodiment is 20°, the influence of the machine shell 1 on the detection area of the radar body 21 is effectively reduced, the detection range of the radar body 21 is larger, the blind area of the edge of the machine body is greatly reduced, and the detection efficiency of the intelligent mower is improved, which is conducive to improving the accuracy of navigation and obstacle avoidance of the intelligent mower.
[0129] In the embodiment, the front end region of the top of the machine shell 1 has a groove structure, and the groove structure has a support surface extending downwardly and obliquely toward the front side of the machine shell 1, and the support surface is connected with the mounting plate 11.

The first sensor device heat sink 31 is used for heat dissipation of the integrated sensor device 2.
[0131] Specifically, the heat generated by the integrated sensor device 2 is transferred through the mounting plate and the first sensor device heat sink 31 to achieve the effect of assisting the heat dissipation of the integrated sensor device 2.
[0132] Further, the first sensor device heat sink 31 comprises a plurality of first heat dissipation fins 311, and the plurality of first heat dissipation fins 311 are arranged at intervals, wherein a heat dissipation gap is formed between the plurality of first heat dissipation fins 311 arranged at intervals, thereby increasing the contact area with air to improve the heat dissipation effect.
[0133] In the embodiment, the first sensor device heat sink 31 and the mounting plate 11 are integrally arranged, which is conducive to heat transfer and also strengthens the overall strength of the first sensor device heat sink 31 and the mounting plate, thereby improving the durability.
[0134] For example, the first sensor device heat sink 31 and the mounting plate 11 can be an integral aluminum casting, which can improve the heat dissipation effect and simplify the overall structure and assembly.
[0135] As shown in Figures 1 to 9 , the mounting plate 11 is also used for heat conduction, and the intelligent mower further comprises a sensor device heat conduction member 6, which is arranged between the integrated sensor device 2 and the mounting plate 11.

[0136] Further, the intelligent mower further comprises a sensing device damping member 7, which is arranged between the integrated sensing device 2 and the mounting plate 11, so that the sensing device damping member 7 can damp the integrated sensing device 2, thereby reducing the vibration and noise of the intelligent mower.
[0137] Further, the sensing device damping member 7 is provided with a mounting hole 71 matched with the sensing device heat conduction member 6, the mounting hole 71 is arranged through the sensing device damping member 7, and the sensing device heat conduction member 6 is arranged in the mounting hole 71, so that the structural compactness can be improved. The sensing device heat conduction member 6 is a heat-conducting silica gel column or a heat-conducting silica gel pad.
[0138] Specifically, the sensing device damping member 7 is elastically connected between the sensing device damping member 7 and the mounting plate 11; the sensing device damping member 7 is used to buffer the vibration force of the integrated sensing device 2 to achieve the function of reducing noise, and has the functions of protecting the integrated sensing device 2 and reducing noise, effectively improving the stability of the installation of the integrated sensing device 2.
[0139] The front end area of the top of the casing 1 provides a groove structure for mounting the integrated sensing device 2, and the groove structure provides a support surface matched with the mounting plate 11 to position the integrated sensing device 2 by positioning the mounting plate 11.
[0140] Further, the inside of the groove structure has a first mounting portion, and the casing 1 has a second mounting portion, in one specific embodiment of the present embodiment, the mounting plate 11 is clamped with the first mounting portion and the second mounting portion to be positioned and installed by clamping, and specifically the first mounting portion and the second mounting portion can be one of a buckle and a clamping groove, and the other of the buckle and the clamping groove is arranged on the mounting plate 11 in a position.
[0141] In another specific embodiment of the present embodiment, the intelligent mower further comprises a fastener, and the mounting plate 11 is connected with the second mounting portion and the second mounting portion by the fastener, and the mounting plate 11 is fixed by the fastener such as a screw.
[0142] In the present embodiment, the first mounting portion is arranged on the groove bottom surface, the mounting plate 11 has a first plate segment, an inclined plate segment and a second plate segment connected in sequence, the first plate segment is abutted with the groove bottom surface and connected with the first mounting portion, the inclined plate segment is abutted with the support surface, and the second plate segment is abutted with the casing 1 and connected with the second mounting portion.
[0143] The mounting plate 11 with a three-segment structure is respectively abutted and fixed with the groove bottom surface, the support surface and the top surface of the casing 1, further improving the stability of the installation of the mounting plate 11.
[0144] It should be noted that the top of the shell 1 of the embodiment has a front end region and a rear end region, wherein the front end region and the rear end region are oppositely arranged along the advancing direction of the intelligent mower, and the front end region is the region on one side of the advancing direction when the intelligent mower is in the working state.
[0145] In the embodiment, the intelligent mower further comprises a cover plate 4, the cover plate 4 is arranged on the support, a sensor device accommodating space is formed between the cover plate 4 and the support, the integrated sensor device 2 is at least partially accommodated in the sensor device accommodating space, the cover plate 4 has a through port 41, and the integrated sensor device 2 is exposed through the through port 41.
[0146] The intelligent mower further comprises a ring-shaped sleeve 5, the ring-shaped sleeve 5 is fixedly connected with the cover plate 4 at the through port 41, the ring-shaped sleeve 5 is provided with a sensor device outlet 51 matched with the integrated sensor device 2, and the integrated sensor device 2 at least partially extends outward from the sensor device outlet 51.
[0147] Further, the ring-shaped sleeve 5 is arranged at the through port 41 and abuts against the outer circumferential surface of the integrated sensor device 2, the ring-shaped sleeve 5 has at least one first heat dissipation port 52, the first heat dissipation port 52 can communicate the sensor device accommodating space and an external space, so that the heat of the integrated sensor device 2 is dissipated. The first heat dissipation port 52 is arranged along the circumference of the ring-shaped sleeve 5 to form an arc-shaped heat dissipation port structure, and the ring-shaped sleeve 5 plays a role of protection and decoration.
[0148] Further, a heat dissipation gap can be further formed between the cover plate 4 and the support in advance, so that the heat of the integrated sensor device 2 is taken away by airflow when passing through, so as to dissipate heat.
[0149] In the embodiment, the cover plate 4 and the support have at least one second heat dissipation port 42, the second heat dissipation port 42 can communicate the sensor device accommodating space and an external space, so that the heat of the integrated sensor device 2 is dissipated.
[0150] Further, the support has the second heat dissipation port 42, the second heat dissipation port 42 is a long strip-shaped hole structure to facilitate ventilation and heat dissipation in the working state of the intelligent mower. The second heat dissipation port 42 can be arranged on the front side of the support to improve the heat dissipation effect.
[0151] In the embodiment, the intelligent mower further comprises a shell 1, and the support is the shell 1. It should be noted that the support can also be a mounting structure arranged on the shell 1, and the integrated sensor device 2 is mounted on the shell 1 through the mounting structure. It should be further explained that the integrated sensor device 2 can be directly mounted on the shell 1, or mounted on the shell 1 through the support having a supporting effect.
[0152] The housing 1 in the embodiment includes oppositely arranged front and rear covers, oppositely arranged first and second side covers, and a top cover connected with the rear cover, the first side cover, and the second side cover. The front cover is connected with the top cover through a mounting plate 11. The front cover, the mounting plate 11, the rear cover, the first side cover, the second side cover, and the top cover enclose a closed cavity. The integrated sensing device 2 is arranged outside the closed cavity.
[0153] In the embodiment, the integrated sensing device 2 is a laser radar. The laser radar emits a laser beam to a target, compares a received signal reflected from the target with a transmitted signal, and obtains relevant information of the target, such as target distance, direction, height, and other parameters, after appropriate processing, so as to detect, track, and identify the target. During the working process of the mower, the terrain in front of the mower needs to be accurately detected to prevent the mower from damaging or endangering the surrounding environment. In the embodiment, a laser radar is arranged in the front of the housing 1 to change the angle of the laser beam emitted by the laser radar, increase the sensing range of the environment in front of the mower, reduce the blind area range, and detect and map the terrain in real time, so as to avoid obstacles and accurately work.
[0154] In the embodiment, the integrated sensing device 2 can be at least partially arranged to protrude from the housing 1. In this way, the integrated sensing device 2 can better perform navigation, obstacle avoidance, and weather detection, such as facilitating the integrated sensing device 2 to detect obstacles in front of and around the housing 1, and facilitating the integrated sensing device 2 to detect the weather, such as rain detection.
[0155] In some specific embodiments, the integrated sensing device 2 is arranged on the housing 1.
[0156] Of course, in an unillustrated specific embodiment, the integrated sensing device 2 can also be placed in a light-transmitting cover to protect the integrated sensing device 2 through the transparent cover, and the arrangement of the transparent cover does not affect the integrated sensing device 2 to perform obstacle avoidance detection, navigation, and weather detection.
[0157] As shown in FIGS. Figure 1 and Figure 2 The integrated sensing device 2 is arranged at the front end region of the top of the support at an angle to the horizontal plane.
[0158] The support is the housing 1, and the integrated sensing device 2 is arranged at the front end region of the top of the housing 1 at an angle to the horizontal plane.
[0159] Specifically, the integrated sensing device 2 is arranged on the housing 1 at an angle to the horizontal plane, so that the front end blind area of the intelligent mower can be reduced to the greatest extent. It should be noted that the integrated sensing device 2 is arranged at the front end region of the top of the housing 1 to monitor the environment in the area in front of the intelligent mower.
[0160] As Figures 1 to 9 shown, in order to reduce the blind area, the laser radar in the embodiment includes a radar body 21, and a horizontal distance L between a laser emitting part of the radar body 21 and a front end of the intelligent mower along a traveling direction is greater than or equal to 30 mm.
[0161] It should be noted that the closer the laser emitting part of the radar body 21 is to the front end of the intelligent mower along the traveling direction, the larger the machine blind area will be, and therefore the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the intelligent mower along the traveling direction needs to be controlled in a range greater than 30 mm.
[0162] Preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the intelligent mower along the traveling direction is 35 mm, preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the intelligent mower along the traveling direction is 38 mm, and preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the intelligent mower along the traveling direction is 40 mm. The horizontal distance L between the laser emitting part of the radar body 21 and the front end of the intelligent mower along the traveling direction is not limited to the listed values, and other values not listed in the range are also applicable.
[0163] Further, when the remaining parameters are determined, when the horizontal distance L between the radar body 21 and the front end of the intelligent mower along the traveling direction is set to be within a range of 40 mm-180 mm, the distance between the detection area of the radar body 21 and the edge of the machine can be controlled to be within a range less than or equal to 0.2 m. When the horizontal distance L between the radar body 21 and the front end of the intelligent mower along the traveling direction is set to be within a range of 40 mm-180 mm, the influence of the machine shell 1 on the detection area of the radar body 21 is effectively reduced, the detection range of the radar body 21 is larger, the blind area of the edge of the machine body is greatly reduced, and the detection efficiency of the intelligent mower is improved, which is beneficial to improve the navigation and obstacle avoidance accuracy of the intelligent mower.
[0164] As Figure 2 shown, the support in the embodiment is the machine shell 1, and along the width direction of the support, i.e., along the width direction of the machine shell 1, the machine shell 1 has oppositely arranged first and second end sides, the first side cover has the first end side, and the second side cover has the second end side. Since the width of the mower body will affect the detection range of the laser radar, when the distance W between the front end of the first end side and the front end of the second end side along the width direction of the machine shell 1 is less than or equal to 600 mm, it can be prevented that the laser radar arranged on the mounting plate 11 cannot detect the environment and terrain on both sides of the machine body.
[0165] In the embodiment, the integrated sensing device is arranged at the front end region of the top of the machine shell 1 at an angle to the horizontal plane.
[0166] Further, the laser radar further comprises a second sensor device heat dissipation piece 22, the second sensor device heat dissipation piece 22 is arranged on the side of the laser radar, and the second sensor device heat dissipation piece 22 is used for dissipating heat of the laser radar.
[0167] In the embodiment, the second sensor device heat dissipation piece 22 is used as a heat dissipation piece of the laser radar itself, and the second sensor device heat dissipation piece 22 comprises a plurality of second heat dissipation fins 221, the plurality of second heat dissipation fins 221 are arranged at intervals, and the heat generated by the laser radar can be dissipated through the design of the second heat dissipation fins 221.
[0168] In the embodiment, the number of the integrated sensor device 2 is only one, and the integrated sensor device 2 is arranged at the front end region of the top of the intelligent mower in the advancing direction.
[0169] In the embodiment, the laser radar can be a semi-solid laser radar, and specifically, the laser radar can be a 3D laser radar.
[0170] The integrated sensor device 2 is a laser radar, the horizontal field of view angle of the laser radar is greater than or equal to 180°, and the vertical field of view angle of the laser radar is greater than or equal to 30°.
[0171] As shown in FIGS. 1, 2 and 3, the integrated sensor device 2 is arranged on the top of the intelligent mower in the advancing direction. Figure 1 and Figure 8 As shown in FIGS. 1, 2 and 3, the integrated sensor device 2 is arranged on the top of the intelligent mower in the advancing direction.
[0172] Preferably, the vertical field of view angle of the laser radar is 40°, preferably, the vertical field of view angle of the laser radar is 50°, and preferably, the vertical field of view angle of the laser radar is 59°. The vertical field of view angle of the laser radar is not limited to the listed values, and other values not listed in the value range are also applicable.
[0173] It should be noted that the greater the vertical field of view angle, the greater the range that can be detected by the laser radar, and the smaller the distance between the area that can be detected by the laser radar and the edge of the machine, and the smaller the blind area. When the laser radar with a vertical field of view angle greater than or equal to 30° is used, and the installation position on the mower is determined by the above-mentioned parameters, the detection range can be improved, and the distance between the detection range of the laser radar and the edge of the machine is reduced, thereby achieving the technical effect of reducing the blind area.
[0174] Further, the mower can detect and map the terrain in real time by arranging one integrated sensor device 2, thereby avoiding obstacles and accurately working, so that the operation of the mower is more stable and safe, and the field of view angle of the integrated sensor device 2 arranged in the application can see the nearest point of the front end, the left end and the right end of the machine, thereby further improving the safety of the operation of the mower.
[0175] In this embodiment, the smart lawnmower does not include other sensors for navigation, obstacle avoidance, and weather detection. This application only needs to set up an integrated sensing device 2 to realize the functions of navigation, obstacle avoidance, and weather detection.
[0176] Specifically, the smart lawnmower does not include any other sensors used for navigation;
[0177] Specifically, the smart lawnmower does not include any other sensors used for obstacle avoidance;
[0178] Specifically, the smart lawnmower does not include any other sensors used for weather detection;
[0179] like Figures 2 to 8 As shown, the center of the lidar in this embodiment is located on the centerline of the width direction of the housing 1. It can be understood that since the housing 1 of the lawnmower is symmetrically designed along the width direction, placing the lidar on the centerline of the housing 1 along the width direction is beneficial for accurately detecting the left and right ends of the front of the machine, and also facilitates obstacle avoidance in the lawnmower.
[0180] The lidar is not limited to the arrangement structure in the above embodiments. It can also be that the center of the lidar is located beside the centerline in the width direction of the housing 1, and the technical effect of detecting terrain and avoiding obstacles can also be achieved by tilting the lidar.
[0181] In some more specific embodiments, only one integrated sensing device 2 for navigation, obstacle avoidance and weather detection of the smart lawnmower is provided. That is, only one integrated sensing device 2 integrating multiple functions of navigation, obstacle avoidance and weather detection is provided, and it is a 3D LiDAR. The 3D LiDAR is located on the center line of the width direction of the housing 1 and on the front end area of the top of the housing 1. The horizontal field of view of the 3D LiDAR is 360° and the vertical field of view is 50°.
[0182] The lawnmower of this invention has only one integrated sensor device 2 on its casing 1. By setting up an integrated sensor device 2, navigation, obstacle avoidance and weather detection functions are realized, which simplifies the hardware structure and overcomes the problem of complex control system caused by the use of multiple external sensors in the prior art. This application saves costs by using only one integrated sensor device 2 and improves the user experience of the product.
[0183] The lawnmower of this utility model can detect and map the terrain in real time by setting an integrated sensor device 2, thereby avoiding obstacles and operating accurately, making the lawnmower more stable and safer to operate. Furthermore, by setting an integrated sensor device 2, the field of view of this application can see the nearest points of the front, left and right ends of the machine, which further improves the safety of the lawnmower operation.

[0267] In the present embodiment, the number of laser radars integrated with the navigation, obstacle avoidance and weather detection functions of the intelligent mower is only one.
[0268] Specifically, only one laser radar is arranged on the casing 1 of the mower, and the functions of navigation, obstacle avoidance and weather detection are realized by arranging one laser radar, thereby improving the functional integration of the laser radar, simplifying the hardware structure, and overcoming the problem of complex control system caused by using multiple external sensors in the prior art. The present application saves cost and improves product experience by using only one laser radar.
[0269] Further, the mower can detect the terrain in real time and build a map by arranging one laser radar, thereby avoiding obstacles and precise operation, so that the operation of the mower is more stable and safe, and the present application can see the nearest point of the front end, left end and right end of the machine by arranging the field of view angle of the laser radar, thereby further improving the safety of the operation of the mower.
[0270] It should be noted that the intelligent mower of the present embodiment does not include other sensors for one of navigation, obstacle avoidance and weather detection, and the present application only needs to arrange one laser radar to realize the functions of navigation, obstacle avoidance and weather detection.
[0271] In some embodiments, the intelligent mower does not include any other sensor for navigation.
[0272] In other embodiments, the intelligent mower does not include any other sensor for obstacle avoidance.
[0273] In other embodiments, the intelligent mower does not include any other sensor for weather detection.
[0274] In the present embodiment, the laser radar position can be arranged protruding from the casing 1, so that better navigation, obstacle avoidance and weather detection can be performed, such as facilitating the laser radar to detect obstacles in front of and around the casing 1, and facilitating the laser radar to detect the weather, such as rain detection.
[0275] In some specific embodiments, the laser radar is arranged on the casing 1.
[0276] Of course, in a specific embodiment not shown, the laser radar can also be placed in the light-transmitting cover to protect the laser radar by the transparent cover, and the arrangement of the transparent cover does not affect the laser radar to detect obstacles, navigate and detect weather.
[0277] As shown in Figures 1 to 3 and Figures 8 to 11 , the laser radar is arranged at an angle at the front end region of the top of the support.
[0278] The support is the machine shell 1, and the laser radar is arranged at the front end region of the top of the machine shell 1 at an angle with the horizontal plane.
[0279] Specifically, the laser radar is arranged on the machine shell 1 at an angle with the horizontal plane, so that the front end blind area of the intelligent mower can be reduced to the maximum. It should be noted that the laser radar is arranged at the front end region of the top of the machine shell 1 to monitor the environment of the area in the forward direction of the intelligent mower.
[0280] Further, as shown in Figure 1 the inclination angle a between the mounting plane of the laser radar and the horizontal plane in the embodiment ranges from 10° to 60°.
[0281] Preferably, the inclination angle a between the mounting plane of the laser radar and the horizontal plane is 15°, preferably, the inclination angle a between the mounting plane of the laser radar and the horizontal plane ranges from 18°, and preferably, the inclination angle a between the mounting plane of the laser radar and the horizontal plane ranges from 28°. The inclination angle a between the mounting plane of the laser radar and the horizontal plane is not limited to the listed values, and other values not listed in the value range are also applicable.
[0282] It should be noted that the mounting plate 11 can be a convex slope, a concave slope, a heterogeneous slope or an inclined plane, etc. Since the laser radar is fixedly mounted on the mounting plate 11, the laser radar is also arranged at an angle. When the inclination angle a between the mounting plane of the laser radar and the horizontal plane is too small, the distance between the detection range of the laser radar and the edge of the machine body is large, and the blind area formed is also large. When the inclination angle a between the mounting plane of the laser radar and the horizontal plane is too large, the laser radar cannot detect the rear side of the mower, which is not conducive to obstacle avoidance.
[0283] Further, when the remaining parameters are determined, the inclination angle a between the mounting plane of the laser radar and the horizontal plane in the embodiment is 20°, which can facilitate controlling the distance between the detection area of the radar body 21 and the edge of the machine within a range of less than or equal to 0.2m. When the inclination angle a between the mounting plane of the laser radar and the horizontal plane in the embodiment is 20°, the influence of the machine shell 1 on the detection area of the radar body 21 is effectively reduced, the detection range of the radar body 21 is larger, the blind area of the edge of the machine body is greatly reduced, and the detection efficiency of the intelligent mower is improved, which is conducive to improving the navigation and obstacle avoidance accuracy of the intelligent mower.

[0285] Further, the intelligent mower further comprises a shock pad arranged between the laser radar and the mounting plate 11. The shock pad is mounted on the mounting plate 11 by means of a fastener such as a screw or a bolt. The shock pad is used to buffer the vibration force of the laser radar to achieve the function of reducing noise, and has the functions of protecting the laser radar and reducing noise, effectively improving the stability of the installation of the laser radar.
[0286] The top of the casing 1 has a groove structure for mounting the laser radar, and the groove structure improves the support surface cooperating with the mounting plate 11 to position the laser radar by positioning the mounting plate 11.
[0287] Further, the inside of the groove structure has a first mounting portion, and the casing 1 has a second mounting portion. In one specific embodiment of the embodiment, the mounting plate 11 is clamped with the first mounting portion and the second mounting portion to be positioned and installed by clamping. Specifically, the first mounting portion and the second mounting portion can be one of a buckle and a clamping groove, and the other of the buckle and the clamping groove is arranged at the corresponding position on the mounting plate 11.
[0288] In another specific embodiment of the embodiment, the intelligent mower further comprises a fastener, and the mounting plate 11 is connected with the second mounting portion and the second mounting portion by means of the fastener, and the mounting plate 11 is fixed by means of the fastener such as a screw.
[0289] In the embodiment, the first mounting portion is arranged on the groove bottom surface, the mounting plate 11 has a first plate segment, an inclined plate segment and a second plate segment connected in sequence, the first plate segment abuts against the groove bottom surface and is connected with the first mounting portion, the inclined plate segment abuts against the support surface, and the second plate segment abuts against the casing 1 and is connected with the second mounting portion.
[0290] The mounting plate 11 with the three-segment structure abuts against and is fixed with the groove bottom surface, the support surface and the top surface of the casing 1, respectively, further improving the stability of the installation of the mounting plate 11.
[0291] It should be noted that the top of the casing 1 of the embodiment has a front end region and a rear end region, wherein the front end region and the rear end region are oppositely arranged in the direction of travel of the intelligent mower, and the front end region is the region on one side of the forward direction of the intelligent mower in the working state.
[0292] As Figures 1 to 3 andFigures 8 to 11 As shown, the center of the laser radar in the embodiment is located on the middle line of the support in the width direction. It can be understood that, since the support of the mower is designed symmetrically along the width direction, the laser radar is arranged on the middle line of the support in the width direction, that is, the machine shell 1, so that the laser radar arranged on the middle line of the machine shell 1 in the width direction is beneficial to accurately detecting the left and right ends of the front part of the machine, and meanwhile, it is convenient for the obstacle avoidance processing in the mower.
[0293] In an embodiment not shown in the figure, the center of the laser radar is located on the side of the middle line of the machine shell 1 in the width direction, and the technical effect of detecting the terrain and avoiding obstacles by the laser radar arranged obliquely can also be achieved.
[0294] As shown in the figure, in order to reduce the blind area, the laser radar in the embodiment includes a radar body 21, and the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is greater than or equal to 30 mm. Figure 1
[0295] It should be noted that, the closer the laser emitting part of the radar body 21 is to the front end of the machine shell 1, the larger the blind area of the machine will be, and therefore, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 needs to be controlled in the range of greater than 30 mm.
[0296] Preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is 35 mm, preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is 38 mm, and preferably, the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is 40 mm. The horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is not limited to the listed values, and other values not listed in the range are also applicable.
[0297] Further, when the remaining parameters are determined, when the horizontal distance L between the radar body 21 and the front end of the machine shell 1 is set in the range of 40 mm-180 mm, it is convenient to control the distance between the detection area of the radar body 21 and the edge of the machine in the range of less than or equal to 0.2 m. When the horizontal distance L between the radar body 21 and the front end of the machine shell 1 is set in the range of 40 mm-180 mm, the influence of the machine shell 1 on the detection area of the radar body 21 is effectively reduced, the detection range of the radar body 21 is larger, the blind area of the edge of the machine body is greatly reduced, and the detection efficiency of the intelligent mower is improved, which is beneficial to improve the accuracy of navigation and obstacle avoidance of the intelligent mower.
[0298] As shown in the figure, in order to reduce the blind area, the laser radar in the embodiment includes a radar body 21, and the horizontal distance L between the laser emitting part of the radar body 21 and the front end of the machine shell 1 is greater than or equal to 30 mm. Figure 2 As shown, since the width of the mower body will affect the detection range of the laser radar, when the distance W between the front end of the first side cover and the front end of the second side cover in the width direction of the machine shell 1 is less than or equal to 600mm, it can be prevented that the laser radar arranged on the mounting plate 11 cannot detect the environment and terrain on both sides of the body.
[0299] In this embodiment, as shown in the figure, Figure 8 The horizontal field of view angle A of the laser radar is 360°, as shown in the figure, Figure 1 The vertical field of view angle B is greater than or equal to 30°.
[0300] Preferably, the vertical field of view angle of the laser radar is 40°, preferably, the vertical field of view angle of the laser radar is 50°, preferably, the vertical field of view angle of the laser radar is 59°. The vertical field of view angle of the laser radar is not limited to the listed values, and other values not listed in the value range are also applicable.
[0301] It should be noted that the larger the vertical field of view angle, the larger the range that can be detected by the laser radar, and the smaller the distance between the area that can be detected by the laser radar and the edge of the machine, and the smaller the blind area. When using a laser radar with a vertical field of view angle greater than or equal to 30° and determining the installation position on the mower according to the above parameters, the detection range can be improved while reducing the distance between the detection range of the laser radar and the edge thereof, thereby achieving the technical effect of reducing the blind area.
[0302] From the above technical solutions, the present application has the following beneficial effects:
[0303] The intelligent mower of the present application comprises a first heat dissipation device 3 for cooling the laser radar, which realizes heat dissipation of the laser radar and avoids the heat generated during operation of the laser radar from affecting the detection accuracy of the laser radar.
