[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 efforts are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1 and Figure 2 As shown, this embodiment 1 discloses a garden trimming robot. The robot has a single-layer structure and specifically includes a shell component, a cutting motor component 2, a drive component 3, a collection component 4, a solar device 5, a charging device 6 and a control component.

[0042] like Figure 1 As shown, the housing assembly includes an outer shell (not shown) and a base 12. The outer shell and base 12 are connected by bolts. The robot of Example 1 is designed to be low-lying to meet market demand, with the outer shell positioned low and the base 12 as close to the ground as possible. The robot's width does not exceed 60 cm, and its height does not exceed 40 cm. Side panels 13 are provided on both sides of the base 12 to prevent splashing of grass clippings or other cut plants.

[0043] like Figure 3 and Figure 4 As shown, the cutting motor assembly 2 includes a motor 21, a detachable assembly 22 and a cutting assembly 23. The detachable assembly 22 includes a sleeve fixing seat 221, a sleeve cover 222 and an elastic washer 223. 2 to 3 mounting blocks are evenly arranged on the outside of the bottom of the sleeve fixing seat 221, a mounting hole is provided in the middle of the mounting block, and corresponding matching holes are also provided on the base 12. The mounting blocks and the base 12 are connected by bolts and nuts. The elastic washer 223 is placed at the bottom of the inner side of the sleeve fixing seat 221, and the motor 21 is placed above the elastic washer 223. The upper part of the sleeve fixing seat 221 is provided with 2 to 3 slots to provide ample space for the insertion of the motor 21. The outer wall of the sleeve fixing seat 221 is provided with a thread connected to the sleeve cover 222, and the inner wall of the sleeve cover 222 is provided with an internal thread. When the motor 21 is placed in the sleeve fixing seat 221, the sleeve cover 222 is inserted into the sleeve fixing seat 221 from above the motor 21 and gradually tightened; at the same time, a pressure cover extends from the top of the sleeve cover 222 to press the top of the motor 21. The top of the sleeve cover 222 also extends with a rotating grip portion that facilitates the user to exert force. The inner diameter of the lower part of the sleeve fixing seat 221 is smaller than the inner diameter of the upper part of the sleeve, so that the lower part of the sleeve fixing seat 221 can clamp the motor 21, ensuring that the motor 21 does not shake when working.

[0044] like Figure 3 and Figure 5 As shown, the cutting assembly 23 includes a threaded sleeve 234, a cutting element 232, and a threaded base 235. One end of the threaded sleeve 234 is connected to the output shaft of the motor 21, and the other end is threadedly mounted on the threaded base 235. The threaded base 235 is provided with an annular body 236, the outer wall of which is threaded for connection with the threaded sleeve 234. The annular body 236 is provided with a pair of mounting grooves 237. The cutting element 232 of this embodiment 1 preferably uses a nylon rope as the cutter head. One end of the nylon rope is passed through the mounting grooves 237 on both sides in sequence, so that the nylon rope is fixed in the mounting grooves 237. Of course, the cutting element 232 includes but is not limited to nylon rope, and can also be a disc-shaped blade, a long strip blade, etc. The threaded sleeve 234 corresponding to the cutting assembly 23 can be 6 cm, 8 cm, or 10 cm, etc., to meet different height requirements for cutting grass or plants. The cutting assembly 23 is pre-installed at the bottom of the motor 21 and can be installed or removed from the robot base 12 together with the motor 21 via the detachable assembly 22. When the user needs to adjust the height of the grass or plants being cut, they only need to disassemble the motor 21 with the cutting assembly 23, adjust the height of the cutting element 232 of the cutting assembly 23, and then reinstall it. This cutting motor assembly 2 is simple, convenient, fast, energy-saving, and low-cost.

[0045] like Figure 1 As shown, the robot has a drive assembly 3, one on each left and right side. Each drive assembly 3 includes a drive motor 31, a drive wheel 32, a driven wheel 33, and a track 34. The left and right drive motors 31 are fixedly mounted on the rear of the base 12. The left and right drive wheels 32 are fixedly connected to the output shafts of the corresponding drive motors 31, and the left and right driven wheels 33 are rotatably mounted on the front of the base 12. The track 34 is mounted on the drive wheel 32 and the driven wheel 33. Both the drive wheel 32 and the driven wheel 33 have latches that engage with the tooth holes in the track 34 to ensure its tracking. The driven wheel 33 assists in rotation, supporting and tensioning the track 34. Compared to tires, the use of tracks 34 significantly enhances the robot's off-road capabilities. Furthermore, because the track 34 has a larger contact area with the ground than the tire, the pressure exerted by the track 34 on the grass or other plant surface is less than that exerted by the tire, preventing the track from damaging the grass or other plant surface and leaving a trail. During travel, two drive motors 31 control the forward and reverse rotation of the tracks 34 located on the left and right sides of the base 12, respectively, to achieve left and right turns and U-turns. The drive motor 31 used in this embodiment 1 includes a reducer; the total power of the selected drive motor 31 must be at least 600W. The tracks 34 are concealed within the outer casing, with only the bottom of the tracks 34 exposed, protecting them and extending their service life. The parallel installation of the tracks 34 reduces their height compared to a triangular installation, giving the robot a lower overall posture and a more low-lying style.

[0046] like Figure 2 As shown, the collecting assembly 4 includes a collecting rake 41 that can rotate around the base 12. The collecting rake 41 is hinged to the rear of the base 12, and is vertically suspended at the rear of the base 12 with the assistance of gravity or damping, forming a collecting bin 42 with the base 12 and the side panels 13. The grass clippings or other plants broken by the cutting assembly 23 will be collected by the collecting rake 41 in the collecting bin 42. When the collection volume is full, the collecting rake will be opened, and the grass clippings or other plants will flow out from the bottom of the opened rake to form a haystack. Specifically, the collecting rake 41 is composed of a plurality of metal rods welded to a rectangular baffle. The bottom of the metal rods is exposed on the rectangular baffle and is bent toward the collecting bin 42. This structure facilitates the collection of grass clippings or other plants.

[0047] like Figure 1 and Figure 6 As shown, the solar device 5 is mounted on the upper surface of the robot base 12. The solar device 5 includes a solar box 51, which houses a battery 52, an inverter 53, a DC load 54, an AC load 55, a solar power controller 56, and a solar panel assembly 57. The solar panel assembly 57 is mounted at the top of the solar box 51 and covers the outer shell of the robot, converting solar energy into electrical energy and storing it in the battery 52. ​​The solar panel used in this embodiment 1 is 2 mm thick and can be bent in one direction, which not only increases the absorption area but also allows it to absorb sunlight from different directions. The battery pack in the battery 52 uses four 12V batteries. In this embodiment 1, the battery 52, DC load 54, and solar panel assembly 57 are electrically connected to the solar power controller 56, the inverter 53 is electrically connected to the battery 52, and the AC load 55 is electrically connected to the inverter 53.

[0048] like Figure 1 and Figure 7 As shown, the charging device 6 includes a charging port 61 on the robot and a charging pile 8. In this embodiment 1, the charging port on the robot is a concave charging interface, and the charging pile is a male charging plug. The charging port 61 is located in front of the base 12 of the robot. The charging pile 8 includes a charging pile column 81 and a charging parking seat 82. The charging pile column 81 is provided with a male charging plug 83. The charging parking seat includes a parking area 84 and an entrance and exit area 85. The area of ​​the entrance and exit area 85 is larger than that of the parking area 84, which facilitates the robot to enter the charging pile. After entering, the male charging plug 83 directly docks with the concave charging interface for charging. The charging process of the charging device 6 is fully automatically controlled and does not require human intervention.

[0049] The control assembly includes a control panel and a control board (not shown). The control panel and control board are integrated and mounted on the upper surface of the housing. The control panel displays information such as battery level and maintenance deadline. The control assembly also includes an emergency stop button, which is located on the housing surface.

[0050] The implementation process of this embodiment 1 is as follows:

[0051] Before use, install the cutting assembly 23 according to the desired mowing height. First, assemble the cutting assembly 23. Select threaded sleeves 234 of varying heights based on the desired mowing height. This embodiment ships with at least three threaded sleeves 234 in varying heights. Install the nylon cord onto the threaded base 235. Then, gradually rotate the threaded base 235 from the bottom to the top of the threaded sleeve 234. Once installed, rotate the threaded sleeve 234 so that the motor 21 mounting hole is aligned with the motor 21 output shaft. The second step is to install the motor 21. First, install the sleeve fixing seat 221 on the base 12 of the robot with bolts, then place the elastic washer 223 on the bottom of the sleeve fixing seat 221, and then put the motor 21 with the cutting assembly 23 into the sleeve fixing seat 221. Finally, put the sleeve cover 222 in and tighten the sleeve cover 222. During the tightening process of the sleeve cover 222, the inner diameter of the sleeve fixing seat 221 will shrink and clamp the motor 21 to ensure that the motor 21 will not shake when working, and the sleeve cover 222 will press the top of the motor 21 to achieve quick installation.

[0052] When working, use the control panel or mobile phone to command the robot to work. At this time, the drive motor 31 of the drive component 3 rotates, driving the drive wheel 32, the driven wheel 33, and the track 34 to rotate. The track 34 can ensure the robot's climbing ability on slopes. When mowing, the grass or other plants broken by the cutting component 23 will be collected and raked into the collection bin 42. When the collection bin 42 is full, the collection rake will be pushed open, and the grass will flow out from the bottom of the rake, forming a pile, which is convenient for the user to collect later. During operation, the robot's electrical energy comes from the electricity converted from solar energy and the electricity provided by the charging pile to the battery 52. ​​When the device power drops to the set line during operation, for example, the power is less than 10%, the control module will control the robot to automatically track back to the charging pile, accurately connect the charging port 61 to the charging pile for charging, and automatically stop charging when the charge reaches the set value.

[0053] If the desired height of grass or other plants needs to be cut differently during the next operation, the operator can adjust the height of the cutting element 232 by rotating the threaded base 235 to disengage the threaded sleeve 234. The operator then unscrews the threaded sleeve 234 at the end of the motor 21 and replaces it with a different length. Finally, the operator reinstalls the threaded sleeve 234 and tightens the threaded base 235. After adjustments are complete, the operator reinstalls the motor 21 and cutting element 23. Removing the motor 21 and cutting element 23 as a whole to adjust the height of the cutting element 232 eliminates the inconvenience of manually adjusting the height of the cutting element 232 from beneath the robot base 12.

[0054] Example 2

[0055] like Figure 8 As shown, the difference between this embodiment 2 and embodiment 1 is that the composition of the detachable component 22 in the cutting motor assembly 2 is different. The detachable component 22 of this embodiment 2 includes a frame fixing seat 24, a frame 25 and an inner hole locker 26. The frame fixing seat 24 includes a frame fixing section 241 and a robot fixing section 242 connected in sequence. A fixing column 243 is provided on the frame fixing section 241, and the function of the fixing column 243 is to achieve longitudinal positioning and connection with the frame 25. The bottom of the robot fixing section 242 is welded to the robot. The wall surface of the robot fixing section 242 is provided with a first side hole 244 for achieving lateral positioning and connection with the frame 25. The frame 25 includes a fixed column connecting section 251, a fixed seat connecting section 252 and a motor mounting section 253 connected in sequence: the fixed column connecting section 251 is provided with a fixing hole 254 that cooperates with the fixed column 243; the wall surface of the fixed seat connecting section 252 is provided with a second side hole 255 that realizes a lateral positioning connection with the frame fixing seat 24; the inner hole locker 26 passes through the first side hole 244 and the second side hole 255 in sequence to lock the frame fixing seat 24 and the frame 25 laterally; the motor mounting section 253 is used to install the motor 21.

[0056] The internal bore clamp consists of a clamp body and an adjustment ring (not shown). The clamp body has a threaded section with a number of retractable balls arranged around the end of the clamp body. The adjustment ring has internal threads and fits over the threaded section. The adjustment ring is adapted to reciprocate along the threaded section to adjust the distance between the adjustment ring and the balls, which is used to clamp the robot's fixed section and the fixed base connection section. The internal bore clamp, also known as the internal bore automatic tensioning fixture, is a commercially available part with an optimized adjustment ring. The internal bore clamp can also be replaced with other quick-fix fixtures.

[0057] Example 3

[0058] like Figure 9As shown, the difference between this embodiment 3 and embodiment 1 is that the cutting assembly 23 is different. The cutting assembly 23 includes a bolt column 231, a cutting piece 232 and a cutter disc 233. One end of the threaded column is fixedly connected to the output shaft of the motor 21, and the other end is installed with the cutting piece 232. The fixation of the nylon rope can be reinforced by knotting or using other auxiliary parts. When using a nylon rope, a pair of through holes are opened on the disk surface of the two cutter discs 233, and a nylon rope passes through the pair of through holes. The cutter disc 233 is composed of two clamping blocks, the inner wall of the clamping block is provided with a thread, and the clamping block is sleeved on the bolt column 231. Tighten the clamping block to clamp the nylon rope between the two.

[0059] The operating principle of this embodiment 3 is as follows:

[0060] First, assemble the cutting assembly 23. Install the cutting piece 232 on the clamping blocks. Install one of the clamping blocks on the bolt column 231. Install it to the position corresponding to the bolt column 231 according to the required height of the grass or other plants to be cut. Then install the other clamping block on the bolt column 231. Finally, rotate and adjust the positions of the two clamping blocks to clamp the cutting piece 232. When the height of the cutting piece 232 needs to be adjusted, the operation can be performed on the disassembled motor 21 and cutting assembly 23. First, rotate one of the clamping blocks to loosen the clamping force on the cutting piece 232, adjust it to the required height, and finally readjust the positions of the two clamping blocks to clamp the cutting piece 232.

[0061] Example 4

[0062] like Figure 10 As shown, this embodiment 4 differs from embodiment 1 in that the drive assembly 3 is different. A set of drive assemblies 3 is provided on each left and right side of the robot. Each set of drive assemblies 3 includes a drive motor 31, a first synchronous pulley 35, a second synchronous pulley 36, two support wheels 37, and a synchronous belt 38. The left and right drive motors 31 are fixedly mounted on the rear of the base 12. The left and right first synchronous pulleys 35 are fixedly connected to the output shafts of the corresponding drive motors 31. The left and right second synchronous pulleys 36 are rotatably mounted on the front of the base 12. The synchronous belt 38 is sleeved around the outer sides of the first and second synchronous pulleys 35, 36.
