[0025] Garden robots are widely used in home lawn management due to their intelligent and automated features. Among them, the mowing module, as one of the core operating mechanisms, is responsible for lawn mowing, especially for trimming grass in boundary areas. The mowing module typically includes a mounting plate and mowing ropes, which are connected to the garden robot's body via a swing arm, allowing it to swing within a certain range to cover irregular areas.

[0026] To conduct systematic and quantifiable aging tests on swing arms, some testing devices use general motor fatigue platforms or manual loading methods to verify the lifespan of the swing arms. For example, some organizations use servo motors to drive single-degree-of-freedom swing arms for single-axis reciprocating fatigue tests, but these usually only support horizontal reciprocating motion at a fixed frequency, making it difficult to simulate the actual operating conditions of garden robots under various terrains and working conditions.

[0027] In addition, some testing devices use linear drive devices to drive the load to slide in order to form periodic impacts, but they cannot achieve coordinated control between the actual swing angle, vertical height and end load.

[0028] In summary, these types of testing devices generally suffer from problems such as limited functionality, restricted degrees of freedom, and inability to simulate actual coupled operation processes, making it difficult to fully reflect the fatigue characteristics and failure mechanisms of the swing arm under complex working conditions.

[0029] Example To address the aforementioned technical issues, this embodiment provides a swing arm aging test device, specifically a grass trimming module swing arm aging test device, used to perform aging tests on the swing arm.

[0030] In related technologies, part of the structure of the swing arm 500 under test is as follows: Figure 1 As shown, the system includes a second connector 510, a third connector 520, a boom 530, and a mounting frame 540. The second connector 510 is fixedly connected to the body of the garden robot, and the third connector 520 is rotatably connected to the second connector 510 about the vertical direction. One end of the boom 530 is rotatably connected to the third connector 520 about the horizontal direction, and the other end of the boom 530 is rotatably connected to the mounting frame 540 about the horizontal direction. The mounting plate of the mowing module is fixed on the mounting frame 540.

[0031] During operation, the third connecting member 520 rotates back and forth vertically relative to the second connecting member 510, which in turn drives the boom 530, mounting frame 540, and the entire mowing module to swing in direction. The boom 530 rotates back and forth horizontally relative to the third connecting member 520, which in turn drives the mounting frame 540 and the entire mowing module to adjust their pitch. During pitch adjustment, the mounting frame 540 and the mowing module remain horizontal at all times.

[0032] Please refer to the following: Figure 2 and Figure 3 The swing arm aging test device includes a test bench 100, a load component 200, a yaw swing component 300, and a pitch swing component 400.

[0033] The test bench 100 is used to mount the swing arm 500 to be tested, and the load 200 is used to connect to the end of the swing arm 500 to be tested that is away from the test bench 100.

[0034] In addition, the yaw swing assembly 300 is used to drive the swing arm 500 under test to swing horizontally, and the pitch swing assembly 400 abuts against the bottom surface of the load member 200 to drive the swing arm 500 under test to swing vertically.

[0035] Understandably, when the pitch swing assembly 400 presses against the bottom surface of the load member 200, the load member 200 moves upward, causing the swing arm 500 under test to swing vertically upward. When the pitch swing assembly 400 moves downward, the load member 200 and the swing arm 500 under test reset downward under their own gravity, that is, the swing arm 500 under test swings vertically downward.

[0036] When testing the swing arm 500 under test using the aforementioned swing arm aging test device, the swing arm 500 is first mounted on the test bench 100 to simulate the state of the swing arm 500 mounted on the body of the garden robot; and the load is connected to the end of the swing arm 500 away from the test bench 100 to simulate the mowing module installed at the end of the swing arm 500. Subsequently, the swing arm 500 is driven to swing horizontally by the yaw swing component 300 and to swing vertically by the pitch swing component 400. This can simulate the working state of the swing arm 500 during the mowing process, that is, simulate the actual coupled operation process of the swing arm 500. The test results are more accurate, the functions are more diverse, the degree of freedom is higher, and it can better reflect the fatigue characteristics and failure mechanism of the swing arm 500 under complex working conditions.

[0037] Please see Figure 4 In some embodiments, the test bench 100 includes a frame body 110 and a mounting plate 120. The frame body 110 is arranged in a cuboid shape. The mounting plate 120 is disposed on the top of the frame body 110 and is used to mount the swing arm 500 to be tested.

[0038] Understandably, the frame body 110 has a hollow structure, consisting of four vertical edges and eight horizontal edges, which can reduce its own weight while providing rigid support. The mounting plate 120 facilitates the installation of the swing arm 500 to be tested, specifically by installing and fixing the aforementioned second connector 510 on the mounting plate 120.

[0039] Furthermore, in some embodiments, the test bench 100 also includes a reinforcing rod 130. The reinforcing rod 130 is disposed on at least one side of the frame body 110, and its two ends are respectively connected to the side frame of the respective side.

[0040] During testing, the reinforcing rod 130 can improve the bending stiffness of the frame body 110 and prevent the frame body 110 from vibrating and deforming.

[0041] For example, the pitch swing assembly 400 is located on the front of the frame body 110, and the left side, right side and back side of the frame body 110 are provided with reinforcing rods 130, with each reinforcing rod 130 having two ends connected to two vertical edges of the surface on which it is located.

[0042] Furthermore, in some embodiments, the test bench 100 also includes a support frame 140. The support frame 140 is horizontally arranged, and the support frames 140 are arranged in pairs on both sides of the frame body 110 and connected to the bottom of the frame body 110.

[0043] During testing, the support frame 140 can increase the contact area between the entire test bench 100 and the ground, thereby better resisting the inertial swing force, which is the reaction force exerted on the test bench 100 by the swing arm 500 during the swing process.

[0044] For example, the support frame 140 adopts a triangular frame, and the support frame 140 is respectively set at the bottom of the left side and the right side of the frame body 110.

[0045] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the heading oscillation assembly 300 includes a first linear drive 310, a first rotation axis 320, a transmission element 330, and a second rotation axis 340.

[0046] The driving end of the first linear drive 310 is rotatably connected to one end of the transmission 330 via the first rotating shaft 320.

[0047] The transmission component 330 is rotatably connected to the test bench 100 via the second rotating shaft 340, and the other end of the transmission component 330 is connected to the swing arm 500 to be tested.

[0048] The axis of the second rotation axis 340 coincides with the axis of the horizontal swing of the swing arm 500 under test.

[0049] Furthermore, the axis of the first rotation axis 320 is parallel to the axis of the second rotation axis 340.

[0050] During testing, the driving end of the first linear drive 310 translates, causing the transmission component 330 to rotate around the axis of the second rotating shaft 340. Since the end of the transmission component 330 away from the first linear drive 310 is connected to the swing arm 500 under test, and the axis of the second rotating shaft 340 coincides with the axis of the horizontal swing of the swing arm 500 under test, the transmission component 330 can drive the swing arm 500 under test to reciprocate in the horizontal direction around the axis of the second rotating shaft 340, simulating the actual working condition of the grass-cutting module sweeping left and right in grass-cutting operations.

[0051] During this process, the driving ends of the transmission component 330 and the first linear drive component 310 rotate relative to each other around the axis of the first rotating shaft 320, and the transmission component 330 converts the linear displacement of the first linear drive component 310 into the angular displacement of the swing arm 500 to be measured.

[0052] It should be noted that the other end of the transmission component 330 is connected to the swing arm 500 under test, specifically, the transmission component 330 is fixedly connected to the third connecting component 520. Furthermore, the axis of horizontal swing of the swing arm 500 under test specifically refers to the axis of rotation of the third connecting component 520 relative to the second connecting component 510 when the third connecting component 520 is rotatably connected to the second connecting component 510 in the vertical direction.

[0053] In this embodiment, the second rotating shaft 340 is sequentially arranged vertically through the transmission member 330, the third connecting member 520, and the second connecting member 510. On one hand, the third connecting member 520 is rotatably connected to the second connecting member 510 via the second rotating shaft 340. On the other hand, the transmission member 330 is rotatably connected to the second connecting member 510 via the second rotating shaft 340, and the second connecting member 510 is mounted and fixed on the mounting plate 120. Therefore, the transmission member 330 can be indirectly rotatably connected to the test bench 100 via the second rotating shaft 340, while ensuring that the axis of the second rotating shaft 340 coincides with the axis of horizontal swing of the swing arm 500 under test.

[0054] For example, the first linear drive 310 may be an electric actuator or a linear servo module.

[0055] For example, the transmission member 330 is arranged in the shape of a rod. One end of the transmission member 330 along its own length direction is rotatably connected to the driving end of the first linear drive member 310 through the first rotating shaft 320. The other end of the transmission member 330 along its own length direction is fixedly connected to the third connecting member 520. The middle part of the transmission member 330 is rotatably connected to the test bench 100 through the second rotating shaft 340.

[0056] For example, the heading swing component 300 controls the swing arm 500 under test to swing back and forth within a range of ±45°, and the control frequency simulates the actual grass-cutting frequency, such as 1-2Hz, and the cyclic load forms a fatigue condition.

[0057] Furthermore, in some embodiments, the test bench 100 (see reference) Figure 2 The first mounting base 150 is provided on the first linear drive member 310, and the end of the first linear drive member 310 away from the first rotating shaft 320 is rotatably connected to the first mounting base 150.

[0058] In other words, the entire yaw swing assembly 300 is mounted on the test bench 100.

[0059] Furthermore, when the first linear drive member 310 drives the transmission member 330 to rotate around the axis of the second rotating shaft 340, the vertical distance between the first linear drive member 310 and the axis of the second rotating shaft 340 changes continuously. Therefore, the first linear drive member 310 needs to be rotatably mounted on the first mounting base 150 so that the first linear drive member 310 can swing horizontally adaptively.

[0060] For example, the first mounting base 150 is disposed on the mounting plate 120.

[0061] Furthermore, a second mounting base 160 is provided on the test bench 100, which is used to mount the swing arm 500 to be tested.

[0062] Specifically, the second connector 510 is installed and fixed on the second mounting base 160.

[0063] In addition, the yaw oscillation assembly 300 also includes a first connector 350 and an elastic buffer 360. The first connector 350 is connected to the second mounting base 160. One end of the elastic buffer 360 is connected to the first connector 350, and the other end is connected to the transmission member 330.

[0064] It should be noted that you should refer to this again. Figure 1 The second connector 510 is typically equipped with a buffer structure 511, which is located on both sides of the third connector 520. When the third connector 520 swings horizontally relative to the second connector 510 to its extreme position, the third connector 520 abuts against the second connector 510 through the buffer structure 511. At this time, the buffer structure 511 can effectively absorb and disperse the impact force, protecting the second connector 510 and the third connector 520 from damage, while also playing a shock-absorbing role, reducing vibration and noise.

[0065] Based on this, in order to simulate the working condition of the swing arm 500 under test being buffered during horizontal swing, an elastic buffer 360 is set between the transmission component 330 and the test stand 100, so as to more realistically simulate the working state of the swing arm 500 under test swinging in the direction of grass cutting.

[0066] The second connector 510 is connected to the second mounting base 160, thereby being installed and fixed on the test bench 100, and is used to install the elastic buffer 360.

[0067] Please see Figure 6 For example, the second mounting base 160 is disposed on the mounting plate 120. The first connector 350 is directly connected to the second connector 510, and indirectly connected to the second mounting base 160 through the second connector 510. Both the first connector 350 and the second connector 510 remain stationary during testing.

[0068] Alternatively, the first connector 350 can be directly fixed to the second mounting base 160, but this embodiment does not limit this.

[0069] For example, the elastic buffer 360 uses a spring.

[0070] Please refer to it again. Figure 2 and Figure 3 In some embodiments, the load member 200 is arranged in a disk shape. The axis of the load member 200 is vertical, and the load member 200 is rotatably connected to the swing arm 500 to be measured about its own axis.

[0071] During the test, the load component 200 remains horizontal and can rotate relative to the swing arm 500 under test, thereby simulating the centrifugal load or friction load of a real grass-cutting module and further improving the accuracy of the test results.

[0072] For example, the load member 200 is rotatably connected to the mounting bracket 540 about its own axis.

[0073] Please see Figure 7 In some embodiments, the pitch oscillation assembly 400 includes a base 410 and a second linear drive 420. The second linear drive 420 is disposed on the base 410, and the drive end of the second linear drive 420 abuts against the bottom surface of the load member 200.

[0074] Specifically, when the driving end of the second linear drive 420 abuts against the bottom surface of the load 200, the load 200 moves upward, causing the boom 530 to swing upward. When the driving end of the second linear drive 420 moves downward, the load 200 and the boom 530 return to their original position under their own gravity. During this process, the load 200 remains horizontal, simulating the mowing module sweeping flat on the ground, and the load 200 moves up and down relative to the swing arm 500 under test, thereby simulating the pitch angle change between the swing arm 500 under test and the load 200.

[0075] For example, the second linear drive 420 can be an electric actuator or a linear servo module. In addition, a pitch fixing block 411 is provided on the base 410, and the second linear drive 420 is fixedly mounted on the pitch fixing block 411.

[0076] For example, the pitch swing assembly 400 can control the load member 200 to be at a constant height, simulating a flat lawn area. In this case, the load member 200 always maintains a specific distance from the ground, such as 35mm.

[0077] Alternatively, the pitch swing component 400 can also control the periodic change in the height of the load component 200 to simulate regular terrain undulations (such as slopes or gentle rises) and adjust the height of the mowing module up and down at a specific frequency.

[0078] Furthermore, in some embodiments, the base 410 includes a base plate 412 and a buffer pad 413. A second linear drive member 420 is disposed on the base plate 412, and the buffer pad 413 is disposed on the bottom surface of the base plate 412.

[0079] In addition, the pitch fixing block 411 is set on the top surface of the base plate 412.

[0080] During testing, the buffer pad 413 absorbs the impact caused by the pitching motion of the load member 200, protecting the second linear drive member 420.

[0081] For example, four cushioning pads 413 are provided, each located at the top corner of the bottom surface of the base plate 412.

[0082] In summary, when testing the swing arm 500 under test using the aforementioned swing arm aging test device, the swing arm 500 is first mounted on the test bench 100 to simulate the state of the swing arm 500 mounted on the body of the garden robot; and the load is connected to the end of the swing arm 500 away from the test bench 100 to simulate the mowing module installed at the end of the swing arm 500. Subsequently, the swing arm 500 is driven to swing horizontally by the yaw swing component 300 and to swing vertically by the pitch swing component 400. This can simulate the working state of the swing arm 500 during the mowing process, namely, simulating the actual coupled operation process of the swing arm 500. The test results are more accurate, the functions are more diverse, the degree of freedom is higher, and it can better reflect the fatigue characteristics and failure mechanism of the swing arm 500 under complex working conditions.

[0083] The aforementioned swing arm aging test device possesses dual degrees of freedom for yaw and pitch adjustment, supports closed-loop control of swing frequency and angle, and features end-effector load simulation and structural stability. It can achieve a comprehensive, systematic, and engineering-oriented evaluation of the fatigue life, connection reliability, and structural deformation behavior of the swing arm of a garden robot under various working conditions. Its structure is reasonable, and it offers diverse testing methods, including but not limited to single-axis fatigue testing, coupled fatigue testing, and stress superposition testing.

[0084] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0085] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0086] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
