[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0024] In the description of the present application, it should be understood that the terms "upper", "lower" and the like indicate the orientation or positional relationship based on the orientation or positional relationship when the product is normally used.

[0025] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one feature. The drawing 5 of the embodiment of the present application is provided with a coordinate system XYZ, wherein the positive direction of the X axis represents the left direction, the negative direction of the X axis represents the right direction, the positive direction of the Y axis represents the front direction, the negative direction of the Y axis represents the rear direction, the positive direction of the Z axis represents the upper direction, and the negative direction of the Z axis represents the lower direction.

[0026] The embodiment of the present application provides a NFC grass cutting robot, which is shown in combination with FIGS. 1 to 7, comprising a grass cutting machine body 1, an NFC terminal and an NFC inductor 11 arranged on the grass cutting machine body 1, the NFC terminal is suitable for sensing cooperation with the NFC inductor 11, the grass cutting machine body 1 is provided with a main control board 12 and an NFC controller which are electrically connected to each other, the NFC inductor 11 is electrically connected with the NFC controller; when the NFC terminal is close to the NFC inductor 11, after the NFC inductor 11 senses the signal on the NFC terminal, the main control board 12 controls the grass cutting machine body 1 to start or stop.

[0027] The NFC terminal (not shown) is usually a card with NFC function or an electronic terminal with NFC function, the NFC terminal is held by a user, and the NFC controller (not shown) is usually a chip or a sensor. The user can bring the NFC terminal close to the NFC inductor 11 until electromagnetic induction is generated between the NFC terminal and the NFC inductor 11, and a wireless signal connection is established. At this time, the NFC terminal transmits a start signal or a stop signal to the NFC inductor 11, after the NFC inductor 11 receives the signal, the signal is processed and transmitted to the NFC controller, the NFC controller transmits the signal to the main control board 12 after processing, and the main control board 12 controls the start or stop of the grass cutting machine body 1.

[0028] This setup is simple and convenient, saving time. Compared to the traditional button control mode, users do not need to perform complicated password operations, and each adjustment operation is reduced by 5-10 seconds, effectively improving operating efficiency and user experience.

[0029] It is worth noting that during signal transmission, the signals transmitted between the NFC sensor 11, the NFC controller, and the main control board 12 are not necessarily exactly the same. Signal processing and manipulation are existing technologies and will not be described in detail here.

[0030] The NFC sensor 11 is located on the outer surface of the lawnmower body 1. The NFC sensor 11 can also be located at any position on the outer surface of the lawnmower body 1, such as next to the emergency stop button 16, at the front of the lawnmower body 1, at the front left of the lawnmower body 1, at the front right of the lawnmower body 1, or at the rear of the lawnmower body 1. This arrangement makes it easy for users to locate the NFC sensor 11 and facilitates its sensing.

[0031] As shown in Figure 2, the NFC sensor 11 can be set in front of the lawnmower body 1. The lawnmower body 1 includes a casing, and there is a relatively large space in front of the casing. When the NFC sensor 11 is set in front, the size of the NFC sensor 11 can be made larger to facilitate the user to use the NFC terminal for sensing.

[0032] Furthermore, as shown in Figure 4, the NFC sensor 11 can be located on the front side of the lawnmower body 1, allowing users to use the NFC terminal to sense objects on the side of the lawnmower body 1, making the operation more user-friendly.

[0033] As shown in Figures 5 and 6, the lawnmower body 1 has an opening 14 suitable for mounting the NFC sensor 11. The NFC sensor 11 can be positioned on the outer surface of the lawnmower body 1 through the opening 14.

[0034] A sealing ring 141 is provided in the opening 14. The sealing ring 141 is arranged around the NFC sensor 11 and simultaneously abuts against and connects the NFC sensor 11 and the opening 14.

[0035] The NFC sensor 11 protrudes from the surface of the opening 14, facilitating the user to establish a wireless connection by electromagnetic induction between the NFC terminal and the NFC sensor 11. When the NFC sensor 11 is located on the outer surface of the lawnmower body 1, the sealing ring 141 and the NFC sensor 11 are sealed together, thereby preventing rainwater from seeping into the lawnmower body 1 and causing damage to the components.

[0036] As shown in Figure 5, the lawnmower body 1 is provided with a battery compartment 13 and a cover 131 covering the battery compartment 13. The NFC controller and the main control board 12 are both housed in the battery compartment 13.

[0037] The battery compartment 13 houses the battery. In this embodiment, the battery compartment 13 is located at the rear of the lawnmower body 1, and the NFC sensor 11 is located on the upper surface of the battery compartment 13. This arrangement allows the NFC controller, the main control board 12, and the battery to be concentrated in the battery compartment 13, avoiding the formation of multiple mounting cavities inside the lawnmower body 1, resulting in a more compact structure and lower manufacturing costs. At the same time, the circuit harnesses of the NFC sensor 11, the main control board 12, and the battery can be concentrated together, facilitating wiring and installation during production, and also facilitating subsequent maintenance of the lawnmower body 1.

[0038] As shown in Figure 1, the NFC sensor 11 is housed in the battery compartment 13, and the compartment cover 131 is provided with an NFC indicator area 15 for indicating the position of the NFC sensor 11, and the NFC indicator area 15 is located above the NFC sensor 11.

[0039] Because the NFC terminal and the NFC sensor 11 can establish a wireless connection through electromagnetic induction even over a short distance through the casing, it is not necessary to open the cover 131 for sensing. Therefore, without affecting functionality and ease of operation, the NFC sensor 11 can be housed in the battery compartment 13. This arrangement reduces wear and tear on the NFC sensor 11 caused by external factors such as rain, dust, and impacts, thereby increasing the lifespan of the NFC sensor 11.

[0040] When the NFC sensor 11 is located in the battery compartment 13, it becomes difficult for the user to locate it. Therefore, an NFC indicator area 15 can be created using a clearly identifiable object such as colored plastic or a sticker. The NFC indicator area 15 is located on the cover 131 at a position corresponding to the NFC sensor 11.

[0041] In another embodiment, the NFC sensor 11 can also be located next to the battery compartment 13, rather than directly inside the battery compartment 13. This arrangement keeps the NFC sensor 11, the NFC controller, and the main control board 12 close together, allowing the wiring harness to be grouped together for easier wiring and installation during production.

[0042] The number of NFC sensors 11 is two, namely the first NFC sensor and the second NFC sensor; when both the first NFC sensor and the second NFC sensor detect a signal, the lawnmower body 1 starts or stops.

[0043] Furthermore, when the lawnmower body 1 is paused and the second NFC sensor detects a signal, the lawnmower body 1 restarts; when the lawnmower body 1 malfunctions or reports an error, and both the first NFC sensor and the second NFC sensor detect a signal, the lawnmower body 1 starts up.

[0044] Preferably, because safety requirements in the lawnmower industry dictate that machine control should ideally be accomplished through two actions, the first NFC sensor and the second NFC sensor are used to simultaneously control the start and stop of the lawnmower body 1. Using two NFC sensors 11 to control the lawnmower body 1 reduces the possibility of accidental user touches and also facilitates various control logic implementations. Ideally, the control logic of the two NFC sensors can have four states: "on + on", "off + off", "on + off", and "off + on", each state performing a specific function. "On" indicates that the NFC sensor 11 has detected a signal, and "on" indicates that the NFC sensor 11 has not detected a signal.

[0045] Furthermore, two NFC sensors 11 can be configured to control different functions respectively. For example, one NFC sensor 11 can be used to sense signals controlling the switch of the lawnmower body 1, while the other NFC sensor 11 can be used to sense signals controlling the lawnmower body 1 to pause or restart, etc.

[0046] As shown in Figure 5, the lawnmower body 1 is provided with a first protrusion 17 and a second protrusion 18. The first NFC sensor is located on the upper surface of the first protrusion 17, and the second NFC sensor is located on the upper surface of the second protrusion 18.

[0047] The protruding first protrusion 17 and second protrusion 18 make it easier for users to locate the first NFC sensor and the second NFC sensor. Furthermore, there is a vertical distance between the first protrusion 17 and the second protrusion 18, and / or, there is a horizontal distance between the first protrusion 17 and the second protrusion 18.

[0048] When the distance between the first protrusion 17 and the second protrusion 18 is set closer to facilitate user sensing, to avoid false sensing by the user, the first protrusion 17 is set higher than the second protrusion 18, creating a vertical height difference between the first and second NFC sensors. Furthermore, a horizontal distance difference can also exist between the first protrusion 17 and the second protrusion 18. This way, when the user performs a sensing operation using the NFC terminal, both NFC sensors 11 will not be sensed simultaneously, thus preventing malfunction of the lawnmower body 1.

[0049] Preferably, the first protrusion 17 and the second protrusion 18 can be symmetrically arranged on the left and right sides of the lawnmower body 1. This arrangement is more aesthetically pleasing and avoids the possibility of the user accidentally sensing the NFC sensor when the two NFC sensors 11 are too close together.

[0050] Preferably, the lawnmower body 1 is equipped with a Bluetooth module (not shown). The Bluetooth module is used to wirelessly connect with an external electronic terminal via Bluetooth signal. The Bluetooth module is electrically connected to the main control board 12. When the Bluetooth module establishes a wireless connection with the electronic terminal, the NFC sensor 11 can sense and cooperate with the NFC terminal.

[0051] In this embodiment, a Bluetooth connection needs to be established before the NFC sensor 11 can be activated. The electronic terminal is an electronic product with Bluetooth functionality, such as a mobile phone, tablet, or computer.

[0052] Furthermore, a separate NFC sensor 11 can also be set up to control the Bluetooth connection, that is, after the user senses the NFC terminal and the NFC sensor 11, the Bluetooth connection will be automatically established.

[0053] As shown in Figures 1 to 4, an emergency stop button 16 is provided on the outer surface of the lawnmower body 1, and the emergency stop button 16 is electrically connected to the main control board 12. When the user needs to pause the lawnmower body 1, they can press the emergency stop button 16, at which point the lawnmower body 1 enters a stopped state. When the user needs to restart the lawnmower body 1, they need to place the NFC terminal above the NFC sensor 11 for sensing. Furthermore, the NFC sensor 11 can be located next to the emergency stop button 16, thereby facilitating the user's control of the start and stop of the lawnmower body 1.

[0054] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
