[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 2 A high-precision intelligent lawn mowing robot includes a lawn mowing robot body 1. A protective shell 2 is fixedly connected to one side of the lawn mowing robot body 1. An adjustment component 4 is set inside the protective shell 2. The adjustment component 4 includes a connecting seat 401, a connecting rod 402, a connecting plate 403, a connecting rod 404, a gear 405, a connecting seat 406, a reinforcing rope 407, and a drive motor 408. The connecting seat 401 is set on the inner wall of the protective shell 2. The connecting rod 402 is set inside the connecting seat 401. A connecting plate 403 is set on both sides of one end of the connecting rod 402. A connecting rod 404 is set at the bottom of the connecting plate 403. A gear 405 is set at one end of both the connecting rod 402 and the connecting rod 404. A connecting seat 406 is set at one end of the connecting rod 404. A reinforcing rope 407 is set on one side of both the connecting rod 402 and the connecting rod 404. A drive motor 408 is set on one side of the connecting seat 401.

[0026] The mowing robot's cutting height can be adjusted by setting the adjustment component 4 to adapt to different cutting height requirements. By starting the drive motor 408, it works with the first connecting rod 402, the connecting plate 403, the second connecting rod 404, the gear 405, and the second connecting seat 406 to drive the mounting plate 5 and the mowing device 3 to move up and down, thereby adjusting the cutting height of the mowing device 3.

[0027] Please see Figures 1 to 2 Connecting seat 401 is fixedly connected to the inner wall of protective shell 2. One end of connecting rod 402 is rotatably connected to the inside of connecting seat 401. Connecting plate 403 is rotatably connected to the outside of connecting rod 402. Connecting rod 404 is rotatably connected to connecting plate 403. Two gears 405 are fixedly connected to connecting rod 402 and connecting rod 404 respectively, and the two gears 405 mesh with each other. Connecting seat 406 is fixedly connected to the top of mounting plate 5, and one end of connecting seat 406 is rotatably connected to connecting rod 404. Drive motor 408 is fixedly connected to one side of connecting seat 401, and the output shaft is fixedly connected to connecting rod 402.

[0028] By starting the drive motor 408, the first connecting rod 402 is driven to rotate. During the rotation of the first connecting rod 402, the second connecting rod 404 can be driven to rotate synchronously through the two gears 405, so that the first connecting rod 402 and the second connecting rod 404 can expand or contract with each other, thereby driving the second connecting seat 406 to move up and down, and at the same time driving the mounting plate 5 and the mowing device 3 to move up and down.

[0029] Please see Figures 1 to 3 The bottom of the main body 1 of the lawnmower robot is equipped with a control box 7. The bottom of the connecting seat 406 is fixedly connected to the mounting plate 5. The bottom of the mounting plate 5 is equipped with a lawnmower device 3. The lawnmower device 3 includes a drive box 301 and a cutting blade 302. The bottom of the mounting plate 5 is equipped with the drive box 301. Both ends of the bottom of the drive box 301 are rotatably connected to the cutting blade 302.

[0030] The cutting blade 302 is driven to rotate by the drive box 301 to cut the lawn. The GPS transceiver module and control module used for navigation are both located in the control box 7. Therefore, the GPS signal is less affected by the electromagnetic interference of the motor in the drive device during transmission, which greatly improves the sensitivity of navigation.

[0031] Please see Figures 1 to 5 An installation assembly 6 is provided between the mounting plate 5 and the mowing device 3. The installation assembly 6 includes a fixing ring 601, a fixing rod 602, a slider 603, a spring 604, a snap-fit ​​block 605, a snap-fit ​​ring 606, and a snap-fit ​​groove 607. The top of the mounting plate 5 is fixedly connected to the fixing ring 601. The inner wall of the fixing ring 601 is fixedly connected to the fixing rod 602. Both ends of the surface of the fixing rod 602 are slidably connected to the slider 603. The spring 604 is fixedly connected between the two sliders 603. The snap-fit ​​block 605 is fixedly connected to one side of the slider 603. The top of the drive box 301 is fixedly connected to the snap-fit ​​ring 606. The snap-fit ​​groove 607 is opened on both sides of the snap-fit ​​ring 606, and the snap-fit ​​block 605 is located inside the snap-fit ​​groove 607.

[0032] With the installation component 6, the mowing device 3 can be installed and disassembled by snap-fit. The split design makes it convenient for personnel to repair or maintain the mowing device 3. When disassembling, simply press the two sliders 603 to disengage the snap-fit ​​block 605 from the snap-fit ​​groove 607, break the snap-fit ​​relationship, and disassemble the mowing device 3.

[0033] In this invention, the working principle of the device is as follows:

[0034] In use, the drive box 301 drives the cutting blade 302 to rotate and cut the lawn. When the cutting height needs to be adjusted, the drive motor 408 is started to rotate, which drives the first connecting rod 402 to rotate. During the rotation of the first connecting rod 402, the two gears 405 drive the second connecting rod 404 to rotate synchronously, so that the first connecting rod 402 and the second connecting rod 404 can expand or contract with each other, thereby driving the second connecting seat 406 to move up and down. At the same time, the mounting plate 5 and the lawn mowing device 3 can move up and down, thereby adjusting the cutting height of the lawn mowing device 3. When the first connecting rod 402 and the second connecting rod 404 move, the reinforcement rope 407 can increase the stability.

[0035] When the mowing device 3 needs repair or maintenance, move the mowing device 3 to a suitable height, and simultaneously press the two sliders 603. This causes the bottom of the sliders 603 to slide on the fixed rods 602, bringing the two fixed rods 602 closer together. This compresses the spring 604, causing the locking block 605 to disengage from the locking groove 607, breaking the locking relationship. Then, the locking ring 606 can be pulled out from the fixed ring 601 to disassemble the mowing device 3. This allows for repair or maintenance of the mowing device 3, making it easy for personnel to operate and understand. Conversely, inserting the locking ring 606 into the fixed ring 601 allows the locking block 605 to enter the locking groove 607 for locking, thus re-fixing the mowing device 3.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
