In other embodiments, the traveling assembly 20 may also be a crawler chassis, which is not specifically limited in this embodiment of the present application.

[0036] In this embodiment, the control unit 30 may be a programmable controller (PLC). The control unit 30 is disposed on the machine body 10 and is electrically connected to the travel assembly 20 and the cutting drive assembly 50. In other embodiments, the control unit 30 may also be a central processing unit (CPU), a microprocessor, a digital processing chip, or any other processor chip capable of performing data processing functions. The control unit 30 may also be disposed on the swing arm assembly 40 or elsewhere, and this embodiment of the present application is not specifically limited thereto.

[0037] In this embodiment, the swing arm assembly 40 and the cutting drive assembly 50 are both located at the bottom of the machine body 10. When the swing arm assembly 40 drives the cutting drive assembly 50 to move to the first mowing position or the second mowing position, the distance between the installed first cutting head 61 or the second cutting head 62 and the ground is reduced, thereby facilitating the first cutting head 61 and the second cutting head 62 to cut the lawn.

[0038] In this embodiment, the swing arm assembly 40 includes a swing arm 41, which includes a first section 411 and a second section 412. The first section 411 is rotatably connected to the body 10, and the second section 412 is hinged to the first section 411. The cutting drive assembly 50 is located at the end of the second section 412 away from the first section 411. This facilitates the swing arm assembly 40 to drive the cutting drive assembly 50 to the first mowing position or the second mowing position, and facilitates adjustment of the height of the cutting drive assembly 50.

[0039] In some other embodiments, the swing arm assembly 40 may further include a swing drive member (not shown), which may be a motor or a telescopic cylinder. The swing drive member is disposed on the body 10 and connected to the swing arm 41, thereby driving the swing arm 41 to swing, thereby enabling the swing arm assembly 40 to automatically drive the cutting drive assembly 50 to move to the first mowing position or the second mowing position.

[0040] In this embodiment, the cutting drive assembly 50 also includes a rotating drive member 51, which is arranged at the end of the second section 412 of the swing arm 41 away from the first section 411. The rotating drive member 51 can be a motor, and the mounting joint 52 is connected to the rotating drive member 51. The rotating drive member 51 drives the mounting joint 52 to rotate, and the mounting joint 52 drives the first cutting head 61 or the second cutting head 62 to rotate to cut the lawn.

[0041] Please refer to Figure 4 and Figure 5 In this embodiment, both the first cutting head 61 and the second cutting head 62 include a connector 611. A slot 521 is defined on the mounting joint 52, and a hook 6111 is disposed on the connector 611 to engage with the slot 521. When connecting the first cutting head 61 or the second cutting head 62 to the mounting joint 52, simply engage the hook 6111 with the slot 521, thereby improving the convenience and efficiency of installing the first cutting head 61 or the second cutting head 62.

[0042] In some other embodiments, the slot 521 may also be provided on the connector 611 , and correspondingly, a hook 6111 engaged with the slot 521 may be provided on the mounting connector 52 . This embodiment of the present application does not specifically limit this.

[0043] In this embodiment, there are multiple slots 521 and hooks 6111, and the multiple slots 521 correspond to the multiple hooks 6111. This improves the firmness and stability of the connection between the first cutting head 61 or the second cutting head 62 and the mounting joint 52.

[0044] In this embodiment, the mounting joint 52 is provided with a positioning groove 5221, and the connecting member 611 is provided with a positioning protrusion 6112 that plugs into the positioning groove 5221. When the first cutting head 61 or the second cutting head 62 is connected to the mounting joint 52, the positioning protrusion 6112 plugs into the positioning groove 5221 to maintain positioning, thereby improving the accuracy of the installation of the first cutting head 61 and the second cutting head 62.

[0045] In some other embodiments, the positioning groove 5221 may also be provided on the connector 611 , and correspondingly, a positioning protrusion 6112 that plugs into and engages with the positioning groove 5221 may be provided on the mounting joint 52 . This embodiment of the present application does not specifically limit this.

[0046] In this embodiment, there are multiple positioning protrusions 6112 and multiple positioning grooves 5221, and the multiple positioning protrusions 6112 correspond one-to-one to the multiple positioning grooves 5221. In this way, the accuracy of installing the first cutting head 61 and the second cutting head 62 is further improved.

[0047] In this embodiment, the connecting member 611 further defines a limiting groove 6113, and a plurality of positioning protrusions 6112 are spaced apart at the bottom of the limiting groove 6113. The mounting joint 52 further defines a limiting portion 522 that engages with the limiting groove 6113, and a plurality of positioning grooves 5221 are defined within the limiting portion 522. Thus, when the first cutting head 61 or the second cutting head 62 is connected to the mounting joint 52, the limiting portion 522 is inserted into the limiting groove 6113 for rough positioning, and the plurality of positioning protrusions 6112 are respectively inserted into the corresponding positioning grooves 5221 for fine positioning, thereby further improving the accuracy of mounting the first cutting head 61 or the second cutting head 62.

[0048] Of course, in some other embodiments, when the positioning groove 5221 is opened on the connecting member 611 and the positioning protrusion 6112 is set on the mounting joint 52, the limiting groove 6113 is opened on the mounting joint 52, and multiple positioning protrusions 6112 are spaced apart at the bottom of the limiting groove 6113, the limiting portion 522 is set on the connecting member 611, the limiting portion 522 is plugged into the limiting groove 6113, and multiple positioning grooves 5221 are opened in the limiting portion 522.

[0049] In this embodiment, the cross-section of the limiting groove 6113 is circular, and the limiting portion 522 is cylindrical. In other embodiments, the cross-section of the limiting groove 6113 may also be triangular, square, or the like, and the shape of the limiting portion 522 may be adapted to the shape of the limiting groove 6113. This embodiment of the present application does not specifically limit this.

[0050] In this embodiment, a plurality of positioning protrusions 6112 are evenly arranged along the circumference of the limiting groove 6113 at the bottom of the limiting groove 6113, and a plurality of positioning grooves 5221 are evenly arranged along the circumference of the limiting portion 522 on the side of the limiting portion 522 facing away from the rotary drive member 51. This facilitates the connection of the first cutting head 61 or the second cutting head 62 to the mounting joint 52 and improves the stability of the first cutting head 61 or the second cutting head 62 after connection to the mounting joint 52.

[0051] In this embodiment, the hook 6111 is arranged at the notch of the limiting groove 6113, and the groove 521 is opened on the peripheral side wall of the mounting joint 52, so that when multiple positioning protrusions 6112 are respectively inserted into the corresponding positioning grooves 5221 for precise positioning, the hook 6111 and the groove 521 can be accurately engaged.

[0052] In this embodiment, the mounting connector 52 is provided with a magnetic portion 5222, and the connector 611 is provided with a magnet 6114 corresponding to the magnetic portion 5222. When the first cutting head 61 or the second cutting head 62 is connected to the mounting connector 52, the magnet 6114 is magnetically attracted to the magnetic portion 5222, thereby improving the firmness and stability of the connection between the first cutting head 61 or the second cutting head 62 and the mounting connector 52.

[0053] In some other embodiments, the magnetic attraction portion 5222 may also be provided on the connector 611 , and correspondingly, the magnet 6114 is provided on the mounting connector 52 . This embodiment of the present application does not specifically limit this.

[0054] In this embodiment, the magnetic portion 5222 is disposed in the positioning groove 5221, and the magnet 6114 is disposed in the positioning protrusion 6112. In this way, the attraction generated by the magnetic portion 5222 and the magnet 6114 can quickly align the positioning protrusion 6112 with the positioning groove 5221, thereby improving the convenience and efficiency of installing the first cutting head 61 and the second cutting head 62.

[0055] In this embodiment, the magnetic attraction portion 5222 is disposed at the bottom of the positioning groove 5221 , and the magnet 6114 is disposed at the top of the positioning protrusion 6112 , thereby further improving the convenience and efficiency of installing the first cutting head 61 and the second cutting head 62 .

[0056] In some other embodiments, the magnetic attraction portion 5222 may also be provided on the groove wall of the positioning groove 5221 , and correspondingly, the magnet 6114 is provided on the side wall of the positioning protrusion 6112 . This embodiment of the present application does not specifically limit this.

[0057] In this embodiment, there are multiple magnetic attraction parts 5222 and multiple magnets 6114. The multiple magnetic attraction parts 5222 are respectively disposed in the multiple positioning grooves 5221, and the multiple magnets 6114 are respectively disposed in the multiple positioning protrusions 6112.

[0058] In this embodiment, the mounting connector 52 is made of a magnetic material such as iron or magnetic steel, and the magnetic portion 5222 is the portion of the mounting connector 52 located at the bottom of the positioning groove 5221. In other embodiments, only the portion of the mounting connector 52 located at the bottom of the positioning groove 5221 may be made of a magnetic material, and this embodiment of the present application is not specifically limited to this.

[0059] Please refer to Figure 6 In this embodiment, a push piece 53 and an unlocking piece 54 are also provided on the mounting joint 52. The push piece 53 is slidably inserted into the mounting joint 52 and corresponds to the hook 6111. The unlocking piece 54 is provided on the mounting joint 52 and connected to the push piece 53. The unlocking piece 54 is used to drive the push piece 53 to push against the hook 6111 so that the hook 6111 is disengaged from the slot 521.

[0060] When it is necessary to disassemble the first cutting head 61 or the second cutting head 62, it is only necessary to make the unlocking member 54 drive the pushing member 53 to push against the hook 6111, so that the hook 6111 is disengaged from the slot 521, thereby improving the efficiency and convenience of disassembling the first cutting head 61 and the second cutting head 62.

[0061] In other embodiments, when the slot 521 is formed on the connecting member 611 and the hook 6111 is provided on the mounting joint 52, the abutting member 53 and the unlocking member 54 are provided on the connecting member 611, the abutting member 53 is slidably inserted into the connecting member 611 and corresponds to the hook 6111, and the unlocking member 54 is provided on the connecting member 611 and connected to the abutting member 53, and the unlocking member 54 is used to drive the abutting member 53 to abut the hook 6111, so that the hook 6111 is disengaged from the slot 521. This embodiment of the present application is not specifically limited to this.

[0062] In this embodiment, the unlocking member 54 is a button. A mounting groove 523 is defined on the side of the mounting joint 52 facing away from the rotary drive member 51. A sliding hole 524 is also defined on the peripheral sidewall of the mounting member, communicating with the mounting groove 523. The sliding hole 524 is located on the side of the slot 521 facing away from the rotary drive member 51. The unlocking member 54 is movably disposed in the mounting groove 523 and protrudes from the side of the mounting joint 52 facing away from the rotary drive member 51. The abutting member 53 is slidably disposed in the sliding hole 524. The abutting member 53 is made of an elastic material, and an acute angle is formed between the extending direction of the abutting member 53 and the pressing direction of the unlocking member 54. When the unlocking member 54 is pressed, the unlocking member 54 drives the abutting member 53 toward the rotary drive member 51. The abutting member 53 is deformed by the pressure of the inner wall of the sliding hole 524 and extends out of the sliding hole 524, thereby abutting the hook 6111, causing the hook 6111 to disengage from the slot 521.

[0063] In this embodiment, the unlocking member 54 and the abutting member 53 are an integral structure. Of course, in other embodiments, the unlocking member 54 and the abutting member 53 may also be separate structures, which is not specifically limited in this embodiment of the present application.

[0064] In this embodiment, the cutting drive assembly 50 further includes an elastic member 55, which can be a spring. The elastic member 55 is disposed in the mounting groove 523, and the two ends of the elastic member 55 are respectively connected to the bottom of the mounting groove 523 and the unlocking member 54. This facilitates the reset of the unlocking member 54 and the abutting member 53.

[0065] In some other embodiments, the unlocking member 54 can also be a power member such as a telescopic cylinder, an electric push rod, etc., and the push member 53 can be a push pin. The unlocking member 54 provides power to drive the push member 53 to move so that the push member 53 pushes against the hook 6111. The embodiments of the present application do not make specific limitations on this.

[0066] In this embodiment, the connecting member 611 is provided with an escape hole 6115, which is specifically formed at the bottom of the limiting groove 6113. When the first cutting head 61 or the second cutting head 62 is connected to the mounting joint 52, the unlocking member 54 passes through the escape hole 6115 and extends to the side of the connecting member 611 facing away from the mounting joint 52, making it easier for the user to press the unlocking member 54.

[0067] Please refer again Figure 4 In this embodiment, the first cutting head 61 further includes a first cutting member 612, which is a metal blade. Since the first cutting head 61 is connected to the mounting joint 52 when the mowing robot 100 is in the first mowing mode, the cutting efficiency of the mowing robot 100 is improved by configuring the first cutting member 612 as a metal blade.

[0068] In this embodiment, there are multiple first cutting members 612 , and the multiple first cutting members 612 are evenly installed around the connecting member 611 of the first cutting head 61 .

[0069] Please refer again Figure 5 In this embodiment, the second cutting head 62 includes a second cutting member 621, which is a plastic blade or a mowing rope. Since the second cutting head 62 is attached to the mounting connector 52 when the mowing robot 100 is in the second mowing mode, the plastic blade or mowing rope reduces the risk of the second cutting member 621 causing harm to the user, small animals, and children.

[0070] In this embodiment, there are multiple second cutting members 621 , and the multiple second cutting members 621 are evenly installed around the connecting member 611 of the second cutting head 62 .

[0071] In summary, the lawn mower robot 100 of the present embodiment comprises a body 10, a travel assembly 20, a control unit 30, a swing arm assembly 40, a cutting drive assembly 50, a first cutting head 61, and a second cutting head 62. In a first mowing mode, the cutting drive assembly 50 drives the first cutting head 61 to rotate, forming a first cutting range located inside the outer contour of the body 10. In a second mowing mode, the cutting drive assembly 50 drives the second cutting head 62 to rotate, forming a second cutting range located outside the outer contour of the body 10. This expands the cutting range of the lawn mower robot 100, enabling the lawn mower robot 100 to effectively cut both the main portion and the edges of the lawn, thereby reducing the user's workload.
