DETAILED DESCRIPTION

[0030] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0031] It should be understood that the terms used herein, such as "upper", "above", "lower", "below", etc., indicating spatial relative positions, are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0032] An embodiment of the utility model provides a lawn mowing robot which improves the maintenance efficiency of electrical components and user experience.

[0033] This embodiment provides a lawn mowing robot 100, which can mow grass on a lawn. Figure 1 As shown, the mowing body 60 , the electrical component 301 and the vehicle body shell include a first shell 10 and a second shell 20 . The first shell 10 encloses at least a part of the vehicle body space 101 , and the mowing body 60 is accommodated in the vehicle body space 101 .

[0034] The mowing body 60 may include a motor, a main control board, a battery pack, and various wiring harnesses, such as wires connecting the main control board and the battery pack, and wires connecting the main control board and various electrical components.

[0035] In addition, the lawn mower robot 100 further includes a base 70 , which is fixedly connected to the first shell 10 . The base 70 and the first shell 10 enclose a vehicle body space 101 . When it is necessary to remove components of the lawn mower body 60 , the base 70 and the first shell 10 need to be disassembled.

[0036] like Figure 1 and 2 As shown, the first housing 10 and the second housing 20 of this embodiment enclose a maintenance space 201, the electrical component 301 is at least partially accommodated in the maintenance space 201, and the second housing 20 is detachably connected to the first housing 10. When the second housing 20 is removed, the electrical component 301 can be separated from the mowing robot 100. By designing the detachable second housing 20, when it is necessary to disassemble the electrical component 301, only the second housing 20 needs to be disassembled, without opening the base 70, and without involving those components of the mowing body 60, which simplifies the maintenance process.

[0037] As described in the background technology, when the existing electrical components 301 are repaired, on the one hand, it is necessary to remove the complex wiring inside the lawn mower robot 100, which involves the plugging and unplugging of these wiring harnesses 90; on the other hand, it is necessary to take out a large number of parts inside the lawn mower robot 100. When the electrical components 301 in this embodiment are repaired, the electrical components 301 can be disassembled by simply opening the second shell 20, without involving the structure of the lawn mower body. In other words, the problems in the background technology can be avoided. After removing the second shell 20, the electrical components 301 can be easily separated from the lawn mower robot 100, thereby significantly improving the convenience and efficiency of maintenance and reducing maintenance time and operation complexity.

[0038] Furthermore, if Figure 2 As shown, the first shell 10 includes a wiring hole 11, the vehicle body space 101 and the maintenance space 201 are connected through the wiring hole 11, and the lawn mowing robot 100 also includes a wiring harness 90, which passes through the wiring hole 11 and connects the lawn mowing body 60 and the electrical component 301 respectively.

[0039] The wiring harness 90 here can be connected to the main control board in the mowing body 60 at one end and connected to the main bus harness 90 of each electrical component 301 in the maintenance space 201 at the other end. By setting a wiring hole 11 on the first shell 10, the vehicle body space 101 and the maintenance space 201 are connected, and the wiring harness 90 is used to connect the electrical component 301 and the mowing body 60. This design does not involve disassembly and assembly of the main control board during maintenance, and only requires disconnecting the wiring harness 90 from the electrical components, ensuring that the wiring harness 90 does not need to completely remove other components when replacing the electrical component 301, further simplifying the operation process and improving maintenance efficiency.

[0040] like Figure 3 As shown, the second shell 20 can be used as a decorative shell and is arranged on the outer surface of the lawn mowing robot 100. Based on this, the requirements for the appearance aesthetics and processing precision of the first shell 10 can be reduced. This embodiment separates the components that realize the function from the components that realize the appearance, and can be produced in a manner that is more suitable for the characteristics of both, thereby improving the flexibility of processing.

[0041] In addition, since the maintenance space 201 enclosed by the second shell 20 and the first shell 10 only serves to accommodate some components, and the vehicle body space 101 enclosed by the first shell 10 and the base 70 accommodates the mowing body 60, the volume of the maintenance space 201 can be much smaller than that of the vehicle body space 101.

[0042] Furthermore, the second shell 20 is detachably connected to the first shell 10 via a snap-fit ​​member and / or a second connecting member 82 .

[0043] The second housing 20 and the first housing 10 can be connected and assembled by means of buckles, bolts, etc. In this embodiment, Figure 4 As shown, the base 70 is arranged on a side of the first shell 10 away from the second shell 20, and the second connecting member 82 passes through the base 70 and the first shell 10 in sequence to be detachably connected to the second shell 20. When the second shell 20 needs to be removed, the second connecting member 82 connected to the second shell 20 is removed from the positions of the plurality of through holes 71 of the base 70, and then the second shell 20 is separated from the buckle connected to the first shell 10, so that the second shell 20 can be removed. The state after the second shell 20 is removed is as shown in FIG. Figure 5 shown.

[0044] In order to clearly express the position and direction described in this embodiment, in this embodiment, the up and down are defined as the direction when the mowing robot 100 is placed on the horizontal ground in a normal mowing posture, that is, the up and down are defined with reference to the direction of gravity, the normal forward direction of the mowing robot 100 is the front, and the reverse direction is the back. The base 70 of this embodiment is located below the first shell 10, and the second shell 20 is located above the first shell 10. In addition, the two sides of the plane where the up and down front and back are located are the left side and the right side, respectively.

[0045] The electrical component 301 of this embodiment may be a component that is easily damaged on the lawn mower robot 100, that is, during the life cycle of the lawn mower robot 100, those components that are more likely to break are placed in the maintenance space 201, while the less damaged structures are placed in the vehicle body space 101. In this way, opening the second shell 20 can meet the needs of replacing most parts of the lawn mower robot 100.

[0046] Below, the electrical component 301 is explained by taking the panel assembly 30, the camera assembly 50 and the distance measuring assembly 40 as examples.

[0047] like Figure 5 and 6 As shown, the electrical component 301 includes a panel assembly 30 , and the second shell 20 includes an opening 21 . At least a portion of the panel assembly 30 is exposed through the opening 21 for operation. The panel assembly 30 is fixedly connected to the first shell 10 and / or the second shell 20 in the maintenance space 201 .

[0048] In this embodiment, the panel assembly 30 is disposed on the top of the lawn mower robot 100 and is exposed from the top of the lawn mower robot 100 through the opening 21. Figure 1 , 2 As shown in FIGS. 3 and 5 , the user can operate the lawn mower robot 100 from the top of the lawn mower robot 100 , and can also conveniently operate the panel assembly 30 after removing the second shell 20 from the top. This design allows the user to conveniently operate and replace the panel assembly 30 , thereby improving the user experience and the convenience of operation.

[0049] The panel assembly 30 includes a control panel 32 and a panel housing 31. The control panel 32 is fixedly connected to the panel housing 31. An interaction portion 3111 may be provided on the panel housing 31, i.e., a component for a user to interact with the lawn mower robot 100, such as a button, a display, etc., and the interaction is exposed from the opening 21 and arranged upward. The control panel 32 may be a circuit board for controlling the lawn mower robot 100. The control panel 32 may be connected to the first housing 10 or the second housing 20 by screws, buckles, etc. Figure 5 In the figure, a connecting portion 314 is provided on the panel shell 31 , and the connecting portion 314 can be in the form of a through hole 71 . A threaded hole is provided on the first shell 10 , and the first connecting member 81 is provided as a bolt. The panel shell 31 is fixedly connected to the first shell 10 through the first connecting member 81 .

[0050] like Figure 6 As shown, the wiring harness 90 includes a panel connection line 91 , which is connected to the panel assembly 30 , and the panel assembly 30 can be separated from the panel connection line 91 when the second housing 20 is removed.

[0051] The panel connection line 91 may include a plug-in terminal connected to the end, and a plug-in port is provided on the control panel 32. During installation and disassembly, it is only necessary to insert or unplug the plug-in terminal into or out of the plug-in port, so that the panel connection line 91 can be easily separated and replaced from the control panel 32, thereby improving the convenience of production and maintenance operations.

[0052] Furthermore, if Figure 2 As shown, the second shell 20 also includes a peripheral edge 211 surrounding the opening 21. The peripheral edge 211 extends into the maintenance space 201 and fixes the panel shell 31. In this embodiment, the opening 21 is exposed upward, and the peripheral edge 211 extends downward. The peripheral edge 211 can strengthen the fixation and stability of the panel assembly 30, which not only improves the structural strength, but also ensures that the control panel 32 will not easily loosen or shift during use, thereby improving the overall durability.

[0053] That is to say, the control panel 32 can be fixedly connected to the first shell 10 or the second shell 20 by bolts, or a limiting structure can be provided on the first shell 10 or the second shell 20 to clamp the panel shell 31 for fixation.

[0054] like Figure 5 and 6 As shown, the panel housing 31 includes a drainage groove 313 , and the peripheral edge 211 is aligned with the drainage groove 313 . The drainage groove 313 is used to guide the liquid away from the position where the wiring harness 90 is connected to the electrical component 301 .

[0055] This liquid is the liquid splashed on the lawn mowing robot 100, and can also be rainwater. Generally, the purpose is to prevent rainwater. The drainage groove 313 can be connected to the drainage outlet 3131. Figure 6 The middle drainage outlets 3131 are arranged one on the left and one on the right. The drainage outlets 3131 face the first shell 10 . The liquid can be guided to the surface of the first shell 10 through the drainage groove 313 and then flow out along the drainage structure on the first shell 10 .

[0056] The cooperation between the drainage groove 313 and the peripheral edge 211 enables the liquid to be guided to a position away from the wiring harness 90 and the electrical component 301, effectively preventing rainwater from damaging the electrical component 301 and enhancing the protection capability and service life of the equipment.

[0057] In addition, taking the camera assembly 50 as an example, the electrical component 301 further includes the camera assembly 50. The lens of the camera assembly 50 can be directed toward the front of the lawn mowing robot 100. Figure 5 The camera assembly 50 is fixedly connected in the maintenance space 201 . When the camera assembly 50 needs to be removed, similar to the panel assembly 30 , the camera assembly 50 can be removed by opening the second housing 20 to expose the maintenance space 201 inside.

[0058] like Figure 5 As shown, the wiring harness 90 includes a camera connection line 93, and the connection position between the camera assembly 50 and the camera connection line 93 is located in the maintenance space 201. The end of the camera connection line 93 can also be provided with a plug-in terminal, and the camera assembly 50 includes a plug-in port. When installing and disassembling, it is only necessary to insert or unplug the plug-in terminal into or out of the plug-in port, so that the camera connection line 93 can be easily separated from the camera assembly 50 and replaced, thereby improving the convenience of production and maintenance operations.

[0059] In addition, taking the distance measuring component 40 as an example, the electrical component 301 also includes the distance measuring component 40, and the distance measuring component 40 is fixedly connected in the maintenance space 201. Figure 3 and 5As shown, the distance measuring assembly 40 includes a distance measuring head 41, and the first housing 10 or the second housing 20 includes a distance measuring opening 22, through which the distance measuring head 41 is exposed. When the distance measuring assembly 40 needs to be removed, similar to the panel assembly 30, the distance measuring assembly 40 can be removed by opening the second housing 20 to expose the internal maintenance space 201.

[0060] The distance measuring component 40 can be a structure of ultrasonic distance measuring, binocular camera distance measuring, infrared distance measuring, laser distance measuring, etc. In this embodiment, a group of ultrasonic distance measuring components 40 are arranged on the left and right of the lawn mowing robot 100, and the distance measuring head 41 of the distance measuring component 40, that is, the ultrasonic distance measuring head 41 is arranged forward, and the distance measuring opening 22 is also arranged to face forward. The design improves the convenience of installation and maintenance of the distance measuring component 40, and ensures the normal operation and accuracy of the distance measuring function.

[0061] like Figure 5 As shown, the wiring harness 90 includes a distance measuring connection line 92, and the connection position between the distance measuring component 40 and the distance measuring connection line 92 is located in the maintenance space 201. The end of the distance measuring connection line 92 can also be provided with a plug-in terminal, and the distance measuring component 40 includes a plug-in port. When installing and disassembling, it is only necessary to insert or unplug the plug-in terminal into or out of the plug-in port, so that the distance measuring connection line 92 can be easily separated from the distance measuring component 40 and replaced, thereby improving the convenience of production and maintenance operations.

[0062] Compared with the prior art, this embodiment has the following beneficial effects:

[0063] The lawn mower robot 100 uses an innovatively designed second shell 20 that cooperates with the first shell 10 to install the vulnerable electrical components 301 in the maintenance space 201 enclosed by the first shell 10 and the second shell 20, and accommodate the lawn mower body 60 in the first shell 10, so that during maintenance, only the second shell 20 needs to be disassembled, and the faulty electrical components 301 can be replaced and maintained without disassembling the entire lawn mower robot 100. This design greatly simplifies the operating steps, reduces maintenance time and difficulty, and improves maintenance efficiency. In addition, it avoids the plugging and unplugging of a large number of wiring harnesses 90 inside the lawn mower robot 100, reducing the risk of failure caused by improper operation of the wiring harness 90. Therefore, by simplifying the replacement process of the electrical components 301, the maintenance convenience and reliability of the lawn mower robot 100 are improved, and the user experience is significantly improved.
