[0002] A smart lawn mower typically consists of a housing, a mobile device, a cutting mechanism, and a battery pack, which provides the necessary power for the mobile device and cutting mechanism. To use the mower, a pre-set area is set up on the lawn for the mower to cut, and a charging station is placed within the area. If the mower detects a low battery level, it automatically returns to the charging station and docks with the charging terminals to recharge the battery pack. If the battery level subsequently determines it meets operational requirements, it automatically leaves the charging station and continues mowing the lawn in the area.

[0003] There are many ways to implement recharging guidance for smart lawn mowers on the market.

[0054] The terms used in this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention.

Therefore, they should not be construed as limiting the invention.

[0055] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of this specification, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in an appropriate manner.

[0056] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. For example, terms such as "upper," "lower," "front," and "rear" indicating orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the disclosure. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the disclosure.

[0057] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] 1 to 4 , which illustrate an automatic operating system according to an embodiment of the present invention, including an intelligent lawn mower 100 and a charging station 200 for docking and charging the intelligent lawn mower 100 .

[0059] Among them, the smart lawn mower 100 moves and mows grass autonomously in the working area, including a shell 1, a walking module 2 for supporting the movement of the shell 1, a cutting module 3 arranged at the bottom of the shell 1, a control module 4 arranged in the shell 1 for controlling the automatic operation of the walking module 2 and the automatic operation of the cutting module 3, and an energy module 5 for supplying energy to the smart lawn mower 100.

[0060] Referring to Figure 3 , the housing 1 includes a first housing 11 and a second housing 12 connected to the first housing 11. The first housing 11 houses functional mechanisms and modules such as the travel module 2, cutting module 3, control module 4, and energy module 5. The second housing 12 at least partially covers the first housing 11, primarily enhancing the aesthetics and recognition of the smart lawn mower 100.

[0061] It should be noted that the first shell 11 is used as a base to install various functional mechanisms and functional modules, and the second shell 12 is used as an upper cover. This is only an optional embodiment of the present invention. In other embodiments, the second shell 12 can also be used as the base and the first shell 11 can be used as the upper cover.

[0062] The travel module 2 is used to drive the intelligent lawn mower 100 within its working area and includes a drive wheel 21 and auxiliary wheels 22 mounted on the housing 1. Specifically, there are two drive wheels 21, each connected to a corresponding travel motor (not shown). The travel motor drives the drive wheels 21 to rotate, enabling the intelligent lawn mower 100 to move automatically. The auxiliary wheels 22, one or two in number, are located at the front of the intelligent lawn mower 100 and serve primarily as auxiliary support. Although not connected to the travel motor, the auxiliary wheels 22 are driven to roll when supporting the intelligent lawn mower 100.

[0063] With this structural arrangement, the intelligent lawn mower 100 can be controlled by the control module 4 to flexibly move and turn on the work surface. During normal movement, the two travel motors output the same rotational speed, directly driving the intelligent lawn mower 100 or indirectly driving it through a transmission structure such as gears or belts, while the auxiliary wheels 22 also roll accordingly. During turning, the two travel motors output different rotational speeds, causing the intelligent lawn mower 100 to turn toward the drive wheel 21 with the lower rotational speed, or toward the drive wheel 21 that is moving in the reverse direction.

[0064] The cutting module 3 includes at least a cutting element 31 for cutting grass and a cutting motor 32 that drives the cutting element 31. Specifically, the cutting motor 32 is mounted on the first housing 11 of the casing 1 and is electrically connected to the control module 4. The control module 4 can control the start and stop of the cutting motor 32 and adjust the speed of the cutting motor 32. The cutting motor 32 is housed in a motor housing 33. A four-bar linkage is provided between the motor housing 33 and the first housing 11, and the four-bar linkage rotationally connects the motor housing 33 and the first housing 11.

[0065] In this embodiment, when the smart lawn mower 100 encounters obstacles such as rocks and low shrubs while moving, the cutting element 31 does not collide with the obstacle. Instead, it is pushed by the obstacle and drives the motor drum 33 to move in the vertical direction. This prevents damage to the cutting element 31 caused by a hard collision with the obstacle and improves the obstacle-crossing capability of the smart lawn mower 100. It should be noted that the cutting element 31 can be a cutting disc and multiple cutting blades mounted on the cutting disc, or a single cutting blade, without limitation.

[0066] The control module 4 is used to control the automatic movement and operation of the smart lawn mower 100. The functions it performs include controlling the cutting module 3 to start or stop working, generating a walking path and controlling the walking module 2 to walk accordingly, receiving environmental signals detected by the smart lawn mower 100, judging the power level of the energy module 5 and promptly controlling the smart lawn mower 100 to return to the charging station 200 for automatic docking and charging, etc.

[0067] The energy module 5 is used to power the intelligent lawn mower 100 and is mounted within the housing 1. Specifically, the energy module 5 is constructed as a battery pack. The first housing 11 includes a battery pack compartment (not shown) into which the battery pack is removably mounted. The battery pack is electrically connected to the compartment, and wires (not shown) extend from the compartment for electrical connection to the travel module 2, cutting module 3, and control module 4, thereby powering the aforementioned functional modules.

[0068] For ease of understanding, in the present invention, the horizontal working surface that the smart lawn mower 100 passes through during the cutting operation is used as a reference object, the plane parallel to the horizontal working surface is used as the horizontal plane, the direction perpendicular to the horizontal working surface is used as the height direction of the smart lawn mower 100, and the direction in which the smart lawn mower 100 enters the charging station 200 is used as the forward direction.

[0069] The smart lawn mower 100 is provided with a charging terminal 7 electrically connected to the battery pack. Correspondingly, the charging station 200 is provided with a docking terminal (not shown). When the smart lawn mower 100 is docked with the charging station 200, the docking terminal of the charging station 200 is connected to the charging terminal 7 of the smart lawn mower 100 to charge the battery pack.

[0070] The charging station 200 has a flat plate for the smart lawn mower 100 to dock on, which is flat on the ground. When the smart lawn mower 100 is positioned on the flat plate, it can prevent the smart lawn mower 100 from tilting due to uneven ground, thereby preventing the docking terminal 7 from docking with the charging terminal 7.

[0071] The smart lawn mower 100 also includes an infrared sensor 6 that guides the smart lawn mower 100 back to the charging station 200. Specifically, the infrared sensor 6 of the smart lawn mower 100 is configured as an infrared receiver for receiving infrared signals. Correspondingly, the charging station 200 is also equipped with an infrared transmitter (not shown) for transmitting infrared signals. This infrared transmitter cooperates with the infrared receiver to guide the smart lawn mower 100 back to the charging station 200.

[0072] Among them, during the process of recharging and docking the smart lawn mower 100 with the charging station 200, the control module 4 of the smart lawn mower 100 can determine the direction of the smart lawn mower 100 based on the received infrared signal, and can continuously adjust its direction according to the location of the charging station 200 until the smart lawn mower 100 is facing the charging station 200. The control module 4 controls the smart lawn mower 100 to move in the direction facing the charging station 200 until it docks with the charging station 200.

[0073] The housing 1 further includes a terminal base 14 that carries the charging terminal 7, and the infrared sensor device 6 is mounted on the terminal base 14. Specifically, the terminal base 14 is mounted on the first housing 11, and the charging terminal 7 is fixedly mounted on the terminal base 14, and the fixed mounting method includes but is not limited to welding or injection molding.

[0074] In this embodiment, the infrared sensor device 6 for implementing recharging guidance is fixedly installed on the terminal seat 14, so that the infrared sensor device 6 does not need additional materials for support and fixation, thereby reducing the manufacturing cost and making the intelligent lawn mower 100 more compact.

[0075] 3 , the second housing 12 is disposed above the first housing 11 , and the first housing 11 and the second housing 12 are connected to define a first cavity 15 , the terminal block 14 is connected to the first housing 11 and defines a second cavity 16 , and the first cavity 15 and the second cavity 16 are in communication.

[0076] Specifically, a first sealing member 81 is provided at the connection between the first housing 11 and the second housing 12 , a second sealing member 82 is provided at the connection between the first housing 11 and the terminal base 14 , and the infrared sensor device 6 is installed in the second cavity 16 .

[0077] In this embodiment, by providing a first sealing member 81 and a second sealing member 82, the first cavity 15 and the second cavity 16 are fluidically connected to each other, but isolated from the external environment. In this way, on the one hand, the infrared sensing device 6 accommodated in the second cavity 16 is isolated from the external environment, and the waterproof sealing effect is good, thereby extending the service life of the infrared sensing device. On the other hand, compared with additionally designing a fixing seat to install the infrared sensing device 6, the waterproof sealing of the infrared sensing device 6 in this embodiment is achieved through the sealing between the terminal seat 14 and the first shell 11, without the need for additional sealing devices, the structure is simple, and the cost is reduced.

[0078] Furthermore, the charging terminal 7 includes a first electrode 71 and a second electrode 72 . The first electrode 71 and the second electrode 72 are respectively accommodated in the second cavity 16 , and the infrared sensor device 6 is installed between the first electrode 71 and the second electrode 72 .

[0079] In this embodiment, by installing the infrared sensor device 6 between the first electrode 71 and the second electrode 72, the space between the first electrode 71 and the second electrode 72 is rationally utilized, making the terminal seat 14 more compact, and further making the intelligent lawn mower 100 more compact.

[0080] The first housing 11 includes a first opening 111 that communicates with the first cavity 15, and the terminal block 14 includes a second opening 141 that communicates with the second cavity 16. The first opening 111 and the second opening 141 are in communication. Specifically, the charging terminal 7 is electrically connected to the control module 4 or the battery pack via a second wire 92. The second wire 92 extends from the electrical connection portion of the charging terminal 7 in the second cavity 16, through the first opening 111 and the second opening 141, into the first cavity 15, and connects to the control module 4.

[0081] Furthermore, the control module 4 and the infrared sensor device 6 are electrically connected through the first wire 91. The control module 4 is at least partially disposed in the first cavity 15, and the infrared sensor device 6 is disposed in the second cavity 16. The above-mentioned first wire 91 extends from the second cavity 16 through the first opening 111 and the second opening 141 to the first cavity 15, thereby realizing the electrical connection between the control module 4 and the infrared sensor device 6.

[0082] Thus, in this embodiment, the interconnected first opening 111 and second opening 141 establish communication between the first cavity 15 and the second cavity 16. The first wire 91 for electrically connecting the infrared sensor device 6 to the control module 4 and the second wire 92 for electrically connecting the charging terminal 7 to the control module 4 or the battery pack are both routed through the first opening 111 and the second opening 141. This simplifies the wiring layout of the intelligent lawn mower and facilitates waterproof sealing. Furthermore, compared to designing an additional mounting base for the infrared sensor device 6, the infrared sensor device 6 and the charging terminal 7 in this embodiment share a wiring channel, which reduces costs and simplifies the structure of the intelligent lawn mower 100.

[0083] Furthermore, the terminal block 14 also includes a third opening 142 communicating with the second cavity 16 and a light-transmitting sheet 143 for external light to pass through. The light-transmitting sheet 143 is mounted in the third opening 142 and cooperates with the third opening 142 to close the third opening 142. Specifically, the infrared sensor device 6 is mounted in the second cavity 16, and the terminal block 14 is provided with the third opening 142. The third opening 142 is located in front of the infrared sensor device 6, and external light can enter the second cavity 16 through the third opening 142. In this way, the infrared sensor device 6 can receive external light through the third opening 142.

[0084] Optionally, in this embodiment, a light-transmitting sheet 143 is also installed at the third opening 142. The light-transmitting sheet 143 covers the third opening 142 and closes the third opening 142. The third opening 142 and the light-transmitting sheet 143 can be connected by gluing or injection molding, thereby improving the sealing of the terminal seat 14.

[0085] Furthermore, the first opening 111 opens downward along the height of the intelligent lawn mower 100, and the second opening 141 opens upward along the height of the intelligent lawn mower 100. Specifically, the interconnected first opening 111 and second opening 141 open opposite each other along the height of the intelligent lawn mower 100. Therefore, when the first and second wires 91 and 92 extend from the second cavity 16 through the first and second openings 111 and 141 and into the first cavity 15, they do not need to bend or adjust their routing, further simplifying the wiring layout of the intelligent lawn mower 100.

[0086] The housing 1 also includes a light shield 18 that is at least partially disposed in front of the terminal seat 14. The light shield 18 is connected to the first housing 11 and / or the second housing 12 and defines a third cavity 17. The terminal seat 14 is accommodated in the above-mentioned third cavity 17. Specifically, the light shield 18 is partially disposed in front of the terminal seat 14 and partially disposed above the terminal seat 14 to cover the terminal seat 14. The light shield 18 is connected to the first housing 11 and defines the third cavity 17 for accommodating the terminal seat 14.

[0087] Therefore, when the smart lawn mower 100 is mowing in an outdoor environment, sunlight and other ambient light are blocked by the light shield 18 and are difficult to illuminate the infrared receiving device 6 hidden deep inside the shell 1. As a result, the infrared receiving device 6 will not be mistakenly triggered by the infrared light in sunlight and other ambient light. The smart lawn mower 100 can accurately perform the recharging action without being affected by the ambient light.

[0088] Furthermore, the infrared sensor device 6 of the intelligent lawn mower 100 is disposed inside the housing 1 to prevent direct exposure to external light. Specifically, the light shield 18 is further provided with a light-transmitting opening 13, through which the infrared sensor device 6 receives external light only. The horizontal distance between the installation position of the infrared sensor device 6 and the light-transmitting opening 13 is no less than 30 mm.

[0089] Therefore, when the smart lawn mower 100 is mowing in an outdoor environment, sunlight and other ambient light are difficult to illuminate the infrared sensor device 6 hidden deep inside the shell 1, so that the infrared sensor device 6 will not be mistakenly triggered by the infrared light in sunlight and other ambient light. The smart lawn mower 100 can accurately perform the recharging action without being affected by the ambient light.

[0090] The infrared sensor device 6 includes a circuit board 61 and a lamp 62 mounted thereon. External light passes through the light-transmitting opening 13 and is irradiated onto the lamp 62. Specifically, the light-transmitting opening 13 includes a first opening wall 131 and a second opening wall 132 disposed below the first opening wall 131. In the height direction of the intelligent lawn mower 100, the lamp 62 is mounted between the first opening wall 131 and the second opening wall 132.

[0091] Therefore, the infrared emitting device of the charging station 200 can be set directly opposite the infrared sensing device 6 of the smart lawn mower 100. When recharging and docking, the infrared light beam emitted by the infrared emitting device can quickly pass through the above-mentioned light-transmitting port 13 to be received by the lamp bead 62, thereby facilitating the recharging and docking between the smart lawn mower 100 and the charging station 200 and improving the recharging and docking efficiency.

[0092] Furthermore, the above-mentioned light-transmitting opening 13 also includes a light entrance point 133, which is arranged at the lower end of the first opening wall 131 and located at the front end of the first opening wall 131. The angle between the connecting line L1 between the light entrance point 133 and the center point of the lamp bead 62 and the horizontal line L2 is not greater than 15 degrees.

[0093] In this embodiment, the size of the light-transmitting opening 13 and the horizontal distance between the lamp bead 62 and the light-transmitting opening 13 are comprehensively designed so that sunlight in most time periods is blocked by the above-mentioned first opening wall 131 and cannot pass through the light-transmitting opening 13 to illuminate the lamp bead 62. In this way, the influence of ambient light such as sunlight on the infrared recharging docking between the smart lawn mower 100 and the charging station 200 is further reduced, thereby improving the recharging docking efficiency.

[0094] The present invention is not limited to the above-described specific embodiments. Those skilled in the art will readily appreciate that many alternatives to the intelligent lawn mower of the present invention exist without departing from the principles and scope of the present invention. The scope of protection of the present invention shall be determined by the claims.
