Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a detachable cutting motor component. Background Art

[0002] Lawns are an integral part of home gardens and urban greening. Regular mowing is a crucial aspect of lawn care. Mowing controls grass height, maintaining it at a consistent height, allowing sunlight to reach the grass base, extending the lawn's green life, and reducing and inhibiting the occurrence of pests and diseases. Generally speaking, robotic mowing requires determining the mowing height based on factors such as grass height, type, growing season, and mowing frequency. Therefore, it's essential for robots to be able to adjust their mowing height.

[0003] Patent publication number CN117016169A discloses an intelligent robot cutterhead lifting device, comprising a frame mounted on the robot body, a cutterhead base mounted vertically on the frame, a mowing disc mounted rotatably on the cutterhead base, and a movable mechanism for driving the mounting frame. The movable mechanism comprises a lifting slider and a drive assembly. The patent utilizes the drive assembly to activate the lifting slider to move vertically, which in turn drives the cutterhead base. This movement of the cutterhead base adjusts the cutting height of the mowing disc, thereby enabling the mowing disc to mow lawns of varying lengths.

[0004] The above technology has the following defects: According to actual surveys, home users or gardeners rarely adjust the mowing height or almost never adjust the mowing height. They regularly use a certain mowing height for mowing operations. Therefore, the utilization rate of the automatic adjustment system with a moving mechanism is extremely low. In addition, this type of automatic robot usually has a high market price due to the high cost of parts and few buyers. Utility Model Content

[0005] The purpose of the utility model is to provide a detachable cutting motor assembly to solve the problems existing in the prior art.

[0023] By adopting the above technical solution, an implementation solution using hole and column matching connection is provided for the detachable components, ensuring the rapid installation of the assembly consisting of the motor and the cutting component on the robot.

[0024] Furthermore, the inner hole locker includes a locker body and an adjustment ring, the locker body is provided with a threaded section, a plurality of balls are provided in a circle at the end of the locker body, the adjustment ring is provided with an internal thread, the adjustment ring is sleeved on the threaded section, the adjustment ring is suitable for reciprocating rotation along the threaded section and adjusting the distance between the adjustment ring and the balls, and the distance is suitable for clamping the robot fixing section and the fixing seat connecting section.

[0025] By adopting the above technical solution, after the inner hole locker is inserted into the first side hole and the second side hole, the rotating adjustment ring can further clamp the robot fixing section and the fixing seat connecting section.

[0026] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention realizes manual adjustment of the cutting piece through the bolt column, cutting piece and cutter disc, and has the advantages of simple structure, low cost, convenient operation of adjusting the height of the cutting piece, convenient replacement of damaged cutting piece, and reusable other accessories with less waste of resources.

DETAILED DESCRIPTION

[0037] 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.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, this embodiment 1 discloses a quickly removable cutting motor assembly, comprising a motor 1, a removable assembly 2, and a cutting assembly 3. The cutting assembly 3 is pre-installed at the bottom of the motor 1 and can be installed or removed from the robot's baseplate along with the motor 1 via the removable assembly 2. To adjust the height of grass or other cut plants, the user simply removes the motor 1 with the cutting assembly 3, adjusts the height of the cutting element 32 of the cutting assembly 3, and then reinstalls it. This cutting motor assembly is simple, convenient, fast, energy-efficient, and low-cost.

[0040] like Figure 2As shown, the removable assembly 2 includes a sleeve fixing seat 21, a sleeve cover 22, and an elastic washer 23. Two to three mounting blocks 211 are evenly distributed on the outside of the bottom of the sleeve fixing seat 21. Mounting holes are provided in the middle of the mounting blocks 211 for connection to the robot's base plate via bolts and nuts. The elastic washer 23 is placed at the bottom of the inner side of the sleeve fixing seat 21, and the motor 1 is placed above the elastic washer 23. One to four notches 212 are provided on the upper portion of the sleeve fixing seat 21, giving the sleeve fixing seat 21 a certain degree of deformation capability and providing ample space for inserting the motor 1. The outer wall of the sleeve fixing seat 21 is provided with a thread for connecting with the sleeve cover 22, and the inner wall of the sleeve cover 22 is provided with an internal thread for connecting with the sleeve fixing seat 21. When the motor 1 is placed in the sleeve fixing seat 21, the sleeve cover 22 is inserted into the sleeve fixing seat 21 from above the motor 1 and gradually tightened; at the same time, a pressure cover 221 extending from the top of the sleeve cover 22 toward the central axis of the sleeve cover 22 is provided. Figure 7 As shown, the pressure cover 221 will press the top of the motor 1. In order to facilitate the user to rotate the sleeve cover 22, a plum blossom petal-shaped rotating grip 222 extends from the top of the sleeve cover 22 away from its axis. The rotating grip 222 includes but is not limited to plum blossom petals, and can also be other shapes that are easy to hold. Finally, the inner diameter of the lower part of the sleeve fixing seat 21 is smaller than the inner diameter of the upper part of the tube, so that the lower part of the sleeve fixing seat 21 can clamp the motor 1 to ensure that the motor 1 does not shake when working.

[0041] like Figure 3 As shown, the cutting assembly 3 comprises a threaded sleeve 34, a threaded base 35, and a cutting element 32. The upper end of the threaded sleeve 34 is provided with a motor mounting hole 341 for threaded connection to the output shaft of the motor 1. The threaded sleeve 34 is hollow and has threads on its inner wall. The threaded base 35 is provided with a protruding annular body 351 with threads on its exterior for connection to the threaded sleeve 34. The annular body 351 is formed with a pair of mounting slots 352 for mounting the cutting element 32. The cutting element 32 of this embodiment 1 preferably utilizes two nylon ropes, which are characterized by their high strength, wear resistance, and impact resistance. One end of the nylon rope is threaded through the two mounting slots 352, and the nylon rope is mounted on the threaded base 35. The threaded base 35 is then gradually rotated upward from the lower portion of the threaded sleeve 34. As the threaded base 35 is secured, the nylon rope is also clamped. Of course, the cutting element 32 includes, but is not limited to, nylon ropes; it can also be a disc-shaped blade, a long blade, or the like.

[0042] The operating principle of this embodiment 1 is as follows: During installation, first assemble the cutting assembly 3. Select threaded sleeves 34 of different heights based on the desired height of the grass or other plants being cut. This embodiment provides users with at least three different threaded sleeve 34 heights. Install the nylon rope onto the threaded base 35. Then, gradually rotate the threaded base 35 from the bottom to the top of the threaded sleeve 34 to install it. After installation, finally rotate the motor mounting hole 341 of the threaded sleeve 34 toward the motor output shaft. Next, install the motor 1. First, bolt the sleeve mount 21 to the robot's base plate. Then, place the elastic washer 23 at the bottom of the sleeve mount 21. Next, insert the motor 1 with the cutting assembly 3 into the sleeve mount 21. Finally, insert the sleeve cover 22 and tighten it. During the tightening process, the inner diameter of the sleeve mount 21 shrinks, clamping the motor 1 tightly to prevent it from shaking during operation. The sleeve cover 22 also compresses the top of the motor 1, allowing for quick installation. When disassembly is required, first unscrew the sleeve cover 22, and the user holds the motor 1 from the slot of the sleeve fixing seat 21, applies force, and takes out the motor 1 and the cutting assembly 3 as a whole to achieve quick disassembly. When the height of the cutting piece 32 needs to be adjusted, the operation can be performed on the removed motor 1 and cutting assembly 3. First, rotate the threaded base 35 and disengage the threaded sleeve 34, then unscrew the threaded sleeve 34 at the end of the motor 1, replace the threaded sleeve 34 with a different length, and finally readjust the threaded sleeve 34 and tighten the threaded base 35. After adjustment, reinstall the motor 1 and cutting assembly 3 according to the steps during installation. Removing the motor 1 and cutting assembly 3 as a whole to adjust the height of the cutting piece 32 solves the inconvenience of the user manually adjusting the height of the cutting piece 32 under the bottom plate of the robot.

[0043] Example 2

The shape of the fixing columns 243 can be circular or rectangular, etc. The function of the fixing columns 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, and 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 laterally lock the frame fixing seat 24 and the frame 25; the motor mounting section 253 is used to install the motor 1.

[0045] The internal bore locker 26 includes a locker body and an adjustment ring (not shown in the figure). The locker body has a threaded section, and a plurality of retractable balls are arranged around the end of the locker body. The adjustment ring has an internal thread and is mounted on 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. This distance is used to clamp the robot's fixed section 242 and the fixed seat connecting section. The internal bore locker 26, also known as the internal bore automatic tensioning fixture, is a commercially available part with only the adjustment ring optimized. The internal bore locker 26 can also be replaced with other quick-fix fixtures.

[0046] The operating principle of this embodiment 2 is as follows:

[0047] The frame mount 24 is pre-welded to the robot's base plate, and the motor 1 is vertically bolted to the motor mounting section 253 of the frame 25, forming a fixed unit. During installation, the motor 1 and frame 25 are installed vertically downward, with the mounting holes 254 of the frame 25 resting on the mounting posts 243 of the frame mount 24. At this point, the motor 1 and frame 25 are fixed in five degrees of freedom: top, bottom, front, back, and one side. Finally, the inner-hole locker 26 is installed in the first and second side holes 244, 255 on the other side, securing the sixth degree of freedom and completing the motor 1's securement, enabling quick installation. For removal, the inner-hole locker 26 is pressed and removed from the first and second side holes 244, 255. The motor 1 and frame 25 unit can then be removed from the frame mount 24, enabling quick removal of the motor 1.

[0048] Example 3

[0049] like Figure 6 and Figure 8 As shown, the difference between this embodiment 3 and embodiment 1 is that the cutting assembly 3 is different. The cutting assembly 3 includes a bolt column 31, a cutting piece 32 and a cutter disc 33. One end of the threaded column is fixedly connected to the output shaft of the motor 1, and the cutting piece 32 is installed on the other end. The nylon rope mowing head is strong, wear-resistant and impact-resistant, which can reduce the risk of other cutting pieces breaking and splashing. The nylon rope can be fixed by knotting or using other auxiliary parts. When using nylon rope, a pair of through holes are opened on the disc surface of the two cutter discs, and a nylon rope passes through the pair of through holes. The cutter disc 33 is 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 31. Tighten the clamping block to clamp the nylon rope between the two.

[0050] The operating principle of this embodiment 3 is as follows:

[0051] First, assemble the cutting assembly 3. Install the cutting piece 32 on the clamping blocks. Install one of the clamping blocks on the bolt column 31 first. Install it to the position corresponding to the bolt column 31 according to the required mowing height. Then install the other clamping block on the bolt column 31. Finally, rotate and adjust the positions of the two clamping blocks to clamp the cutting piece 32. When the height of the cutting piece 32 needs to be adjusted, the operation can be performed on the disassembled motor 1 and cutting assembly 3. First, rotate one of the clamping blocks to loosen the clamping force on the cutting piece 32, adjust it to the required height, and finally readjust the positions of the two clamping blocks to clamp the cutting piece 32.

[0052] Regarding the motor 1 of Examples 1 to 3, a motor 1 with a power of 300W and a rated voltage of 24V can meet the robot usage conditions.

[0053] The utility model can be applied not only to lawn mowing robots, but also to other garden repair robots.
