Through the above structure, the intelligent mower 100 can be controlled by the control module, and can walk and turn on the working surface flexibly. When walking normally, the two walking motors output the same rotating speed, directly drive or indirectly drive the intelligent mower 100 to move through the transmission structure such as gear or belt, and the auxiliary wheels 22 also roll; when turning, the two walking motors output different rotating speeds, and the intelligent mower 100 turns to the side of the driving wheel 21 with lower rotating speed, or the side of the driving wheel 21 corresponding to the direction of retreat.
[0039] The cutting module (not shown) at least includes a cutting member for cutting grass and a cutting motor for driving the cutting member to move. Specifically, the cutting motor is installed on the base 11 of the shell 1, the cutting motor is electrically connected with the control module, the control module can control the start and stop of the cutting motor and adjust the rotating speed of the cutting motor; the cutting motor is accommodated in a motor cylinder, and a four-bar linkage structure is further arranged between the motor cylinder and the base 11, and the four-bar linkage structure is rotationally connected with the motor cylinder and the base 11, so that when the intelligent mower 100 encounters obstacles such as stones and low shrubs during walking, the cutting member will not collide with the obstacles, but will be pushed by the obstacles and drive the motor cylinder to move in the height direction, so that on the one hand, the cutting member can be prevented from being damaged by hard collision with the obstacles; on the other hand, the obstacle crossing ability of the intelligent mower 100 is improved. It should be noted that the cutting member can be a cutting disc and a plurality of cutting blades installed on the cutting disc, or can be a single cutting blade, which is not limited here.
[0040] The control module is used to control the automatic walking and working of the intelligent mower 100, and the functions executed include controlling the cutting module to start or stop working, generating a walking path and controlling the walking module 2 to walk according to the walking path, receiving the environmental signals detected by the intelligent mower 100, judging the power of the energy module and timely controlling the intelligent mower 100 to return to the parking station to automatically dock and charge and the like.
[0041] For the convenience of understanding, in the utility model, the horizontal working surface walked through when the intelligent mower 100 carries out cutting operation is taken as the reference object, the plane parallel to the horizontal working surface is taken as the horizontal plane, the direction perpendicular to the horizontal working surface is taken as the height direction of the intelligent mower 100, the advancing and retreating direction of the intelligent mower 100 is taken as the front and back direction of the intelligent mower 100, and the left and right direction of the intelligent mower 100 is perpendicular to the front and back direction of the intelligent mower 100.
[0042] The intelligent mower 100 comprises a radar module 3 and a metal heat dissipation seat 4 for dissipating heat for the radar module 3.
[0043] The intelligent mower 100 further comprises a heat dissipation piece 5 arranged in the shell 1, the heat dissipation piece 5 comprises a semiconductor refrigeration part 51 and a wire 52 connected with the semiconductor refrigeration part 51, the semiconductor refrigeration part 51 is arranged between the radar module 3 and the metal heat dissipation seat 4, and the wire 52 is electrically connected with the control module.
[0044] The metal heat dissipation seat 4 further comprises a seat body 41 mounted on the shell 1 and a containing groove 42 formed on the seat body 41, and the semiconductor refrigeration part 51 is mounted on the containing groove 42. Specifically, the containing groove 42 is formed by downwardly recessing the upper surface of the seat body 41, and the size and shape of the containing groove 42 are adapted to the semiconductor refrigeration part 51 configured in a sheet shape to accommodate and fix the semiconductor refrigeration part 51. In an embodiment of the present application, the thickness of the semiconductor refrigeration part 51 is not less than the depth of the containing groove 42. In this way, on the one hand, the semiconductor refrigeration part 51 can be stably mounted in the containing groove 42; on the other hand, the part of the semiconductor refrigeration part 51 protruding from the containing groove 42 can be in sufficient contact with the radar module 3 to further quickly conduct heat.
[0045] Further, the metal heat dissipation seat 4 further comprises heat dissipation fins (not shown) formed on the seat body 41, and at least part of the heat dissipation fins surrounds the radar module 3. In this way, on the one hand, the heat dissipation fins further improve the heat transfer speed of the metal heat dissipation seat 4 and improve the heat dissipation effect; on the other hand, the heat dissipation fins surrounding the radar module 3 can protect the radar module 3 in the circumferential direction.
[0046] The first chamber 14 and the second chamber 15 are spatially separated, and the metal heat dissipation seat 4 and the radar module 3 are arranged in the second chamber 15. Specifically, the second chamber 15 is a non-closed chamber, and the radar module 3 and the metal heat dissipation seat 4 are mounted in the second chamber 15. In this way, during the running of the intelligent mower 100, the heat dissipation airflow of the external environment can flow into the second chamber 15 and pass through the metal heat dissipation seat 4, thereby improving the heat dissipation effect of the metal heat dissipation seat 4 and the radar module 3. The first chamber 14 and the second chamber 15 are spatially separated. In this way, the first chamber 14 configured as a closed chamber can accommodate and install a control module with high waterproof requirement without considering the influence of the second chamber 15.
[0047] Further, the decorative cover 13 comprises an air inlet 16 located in front of the radar module 3, and the connection part of the decorative cover 13, the upper cover 12 and / or the base 11 forms an air outlet 17 located behind the radar module 3. In this way, when the intelligent mower 100 is in a working state, the heat generated by the working of the radar module 3 is quickly transferred to the metal heat dissipation seat 4 through the semiconductor heat dissipation part 51. When the intelligent mower advances, the airflow of the external environment flows into the second chamber 15 through the air inlet 16 and passes through the radar module 3 and the metal heat dissipation seat 4, and at the same time, the heat transferred by the metal heat dissipation seat 4 to the air is taken away, and the airflow with heat quickly leaves the second chamber 15 through the air outlet 17. In this way, the heat dissipation effect of the radar module 3 is further improved, and the service life of the radar module 3 is prolonged.
[0048] The utility model is not limited to the above specific embodiment. The person skilled in the art can easily understand that the intelligent mower has many other alternative solutions without departing from the principles and categories of the utility model.
