[0039] With the continuous development of artificial intelligence technology, more and more smart home devices are emerging, among which smart cleaning equipment is becoming increasingly widely used. Taking a robotic vacuum cleaner (or simply a sweeper) as an example, during the cleaning process, the sweeper moves across the surface to be cleaned, removing dirt and impurities. After completing the cleaning task, the sweeper moves to a base station to perform self-cleaning. To ensure the quality of the sweeper, it undergoes functional testing before leaving the factory.

[0040] To improve testing efficiency, this invention improves the treadmill testing device 100 for cleaning equipment. The treadmill testing device 100 will be described in detail below with reference to the accompanying drawings.

[0041] Please see Figures 1 to 3 The runway testing equipment 100 is used for runway testing of cleaning equipment. The runway testing equipment 100 includes multiple test benches 1, which are arranged side by side at intervals in the height direction. In this way, one runway testing equipment 100 can simultaneously test multiple cleaning devices, saving testing time and improving mass production testing efficiency.

[0042] The upper surface of the test bench 1 forms a test surface, and multiple enclosures 2 are installed on it to enclose and form a treadmill channel 3. The treadmill channel 3 includes a first test section 31, a second test section 32, a third test section 33, a fourth test section 34, and a fifth test section 35, which are connected in sequence by bending. The end of the first test section 31 forms a test inlet 36. Before testing, the user places the cleaning equipment to be tested in the test inlet 36.

[0043] During testing, the cleaning equipment will move from test inlet 36 along the first test section 31. When the cleaning equipment encounters step 4 near test inlet 36, its anti-collision function can be tested. After completing the anti-collision test, the cleaning equipment can retreat a predetermined distance towards test inlet 36. At this time, the cleaning equipment can rotate 180° forward and backward to acquire images of the surrounding environment. Subsequently, the cleaning equipment continues to move along the first test section 31 and performs a lifting test at step 4 to test its obstacle-crossing function, enabling the cleaning equipment to step onto step 4.

[0044] The cleaning equipment travels along the first test section 31 to the cleaning area and cleans the carpet 5 in the cleaning area to test the cleaning function of the cleaning equipment. After completing the cleaning test, the cleaning equipment turns and travels along the second test section 32 to the base station 6 at its end, and completes actions such as main unit fan pressurization, recharging, cloth cleaning, cloth removal and charging in the base station 6.

[0045] After completing the predetermined tests within base station 6, the cleaning equipment turns and enters the third test section 33, where it undergoes cliff testing in cliff test area 37. The test examines whether the machine can promptly identify and trigger a stop or turn when encountering cliff scenarios such as steps 4 or slopes, preventing falls and damage. Simultaneously, a checkerboard pattern 7 is installed on the enclosure 2 of cliff test area 37, allowing the cleaning equipment to perform binocular testing. This is used to calibrate binocular camera parameters, verify stereo vision accuracy, and optimize obstacle avoidance algorithms.

[0046] After completing the cliff test, the cleaning equipment continued along the third test section 33, the fourth test section 34, and the fifth test section 35. Upon reaching test exit 38, the cleaning equipment completed the second cliff test at test exit 38. The cleaning equipment completed all functional tests and stopped running.

[0047] In other words, after passing through the first test section 31, the second test section 32, the third test section 33, the fourth test section 34, and the fifth test section 35 in sequence, the cleaning equipment under test can complete basic functional tests such as collision avoidance test, lifting test, cleaning test, recharging and self-cleaning test, binocular test, and cliff test. This creates a smooth test route, shortening the testing time and improving testing efficiency while completing basic functional tests.

[0048] Multiple test benches 1, stacked in a single configuration, are supported and connected by vertical aluminum profiles 8, with multiple aluminum profiles 8 in total. Each test bench 1 has multiple surrounding panels 2, with adjacent panels 2 connected by aluminum profiles 8. To prevent the metal surface and gaps in the aluminum profiles 8 from interfering with the cleaning equipment, in one embodiment, the periphery of the aluminum profiles 8 is covered with a light-colored insulating layer. Preferably, the periphery of the aluminum profiles 8 is covered with a light-colored velvet cloth. This prevents light reflection from the metal surface and light transmission through the gaps in the body from interfering with the testing of the cleaning equipment, thus improving the testing results.

[0049] In this invention, the height between two adjacent test platforms 1 is set to 0.33m to 0.38m. For cleaning equipment, taking a sweeping robot as an example, its body height is typically 8-15cm. Considering the operating space during testing (e.g., the lifting action during a lifting test), setting the distance between the test platforms 1 to 0.33m to 0.38m ensures that the top of the lower machine does not collide with the bottom of the upper platform, thus not affecting the machine's normal movement and turning. Simultaneously, the working distance of the sweeping robot's lidar and vision sensors is mostly between 0.1m and 0.5m. Setting the distance between the test platforms 1 to 0.33m to 0.38m ensures that the detection signals from the upper and lower machines do not overlap, preventing situations where the upper machine's sensor misidentifies the lower machine or platform, or the lower machine misjudges the upper edge as a cliff.

[0050] In this invention, the thickness of the test platform 1 is set to 0.8mm to 1.5mm. This ensures the stability of the test platform 1 during the cleaning equipment's operation.

[0051] In this invention, the test platform 1 uses at least one of the following materials for its test surface: ceramic tile, wood flooring, or artificial leather. The reflectivity of ceramic tiles, wood flooring, and artificial leather (typically 30%–80%) falls within the detection range of the robot vacuum's laser and vision sensors. This prevents the sensors from becoming blind due to excessively low reflectivity, or from causing glare interference due to excessively high reflectivity (like a mirror). Furthermore, these three materials are the mainstream types of household flooring. Using them for the test surface simulates the actual user environment, making the test results for cleaning efficiency, path planning, and material adaptability closer to the real user experience.

[0052] It should be noted that the above three technical features can be selected as one, two, or simultaneously. Specifically, in one embodiment, the above three technical features are simultaneously provided.

[0053] Specifically, the test surface of the test platform 1 can be ceramic tile, wood flooring, or artificial leather. The test surface of the test platform 1 cannot be black. Black surfaces have extremely low reflectivity (usually ≤30%), which can easily be misjudged as cliffs by cliff sensors or prevent visual sensors from recognizing environmental boundaries. Excluding black surfaces can directly avoid such false triggers and ensure the authenticity of test data such as path planning and obstacle avoidance.

[0054] The cleaning equipment travels along the first test section 31 to the cleaning area and cleans the carpet 5.

[0055] In this utility model, the carpet 5 is configured as a gray short-pile carpet 5, and the material of the carpet 5 is set as one of nylon, polyester or polypropylene.

[0056] In this utility model, the two adjacent edges of the carpet 5 are attached to the two adjacent side panels 2 at the corner, and the size of the carpet 5 is set to 0.55m×0.55m~0.5m×0.5m.

[0057] It should be noted that the above two technical features can be set individually or simultaneously. Specifically, in one embodiment, both technical features are set simultaneously.

[0058] After completing the cleaning test, the cleaning equipment needs to get off the carpet 5 and walk along the second test section 32 to the base station 6.

[0059] To further ensure smooth testing of the cleaning equipment, in one embodiment, the central axis of the carpet 5 is collinear with the center of the base station 6 in the extension direction of the second test segment 32.

[0060] The co-line setup eliminates the variable interference of the relative positions of carpet 5 and base station 6. When multiple machines or different batches are tested, they all travel back and forth between base station 6 and carpet 5 along the same straight path. The data benchmarks such as cleaning coverage and recharge path length are consistent, and there will be no comparison error caused by different machine walking routes due to placement offset.

[0061] Meanwhile, when the robot vacuum returns to its charging station, it relies on the infrared and visual signals of the base station 6 for positioning. The collinear setting allows the machine to receive a stable signal along a straight line when returning to the base station 6 from the center of the carpet 5, reducing signal attenuation and positioning deviation caused by angular offset, and avoiding misjudgment of the charging point or charging failure.

[0062] Furthermore, between the carpet 5 and the base station 6, the test surface of the second test segment 32 in this area is continuously arranged.

[0063] Understandably, gaps in the machine's construction can cause the wheels to jam, the side brushes to become tangled, or the mop to get stuck in the gaps, directly interrupting the testing process and increasing rework costs. Setting up continuous test surfaces allows the machine to maintain a stable movement posture, avoiding bumps and steering deviations caused by crossing gaps, and ensuring that testing processes such as cleaning, recharging, and path planning are not interfered with by external structures.

[0064] Meanwhile, gaps between sections can alter parameters such as surface flatness and friction, causing abnormalities in suction adjustment, movement speed, and energy consumption data at these gaps, which do not match the actual operating conditions on a continuous household floor. The continuous test surface setup ensures uniform floor conditions in the second test section 32. When testing multiple machines or different batches, data is obtained using the same floor benchmark, avoiding comparison errors caused by gap variables and making indicators such as cleaning efficiency and battery life more reliable.

[0065] Meanwhile, the floor between base station 6 and carpet 5 in the home (such as tile or wood flooring) is mostly designed to be continuous without gaps, so the test surface remains continuous and can accurately simulate the user's actual usage environment.

[0066] In some application scenarios, it may be necessary to set up splicing positions on the second test segment 32. The splicing positions can be hidden under the carpet 5 or in the base station 6 area. And the splicing gap between the boards must be less than 1mm.

[0067] After the base station 6 completes the predetermined action, the cleaning equipment comes down from the base station 6, rotates 90° and walks a predetermined distance along the third test section 33, then rotates 90° and is set facing the cliff test area 37.

[0068] Please see Figure 1The test surface of the third test section 33 is partially bent outward and extends to form a sunken step structure 371, which forms the cliff test area 37; the outer periphery of the step structure 371 is sealed by the enclosure plate 2. The cleaning equipment performs the cliff test at the step structure 371.

[0069] To ensure testing accuracy, the panel at step structure 371 uses one of the following materials: acrylic, wood, or sheet metal. A black sticker or velvet cloth is affixed to the upper surface of step structure 371, ensuring it is applied horizontally and vertically. It is understood that the black sticker and velvet cloth have extremely low reflectivity (typically ≤30%). By using the black sticker or velvet cloth, step structure 371 more easily approximates the light reflection state of the cliff below where there is no ground, allowing the cliff sensor to quickly identify the absence of ground and accurately trigger the fall prevention command.

[0070] Meanwhile, compared to the inconsistent testing standards caused by the differences in color and material of natural ground, using black stickers or velvet cloth results in stable reflectivity and consistent optical performance across different batches and testing scenarios, thereby improving test consistency and repeatability.

[0071] Specifically, the plurality of enclosures 2 sealing the stepped structure 371 include opposing first and second enclosures. The stepped structure 371 is adjacent to the first test section 31 and the two are separated by the first enclosure; the checkerboard pattern 7 is provided on the side surface of the second enclosure facing the first enclosure.

[0072] A checkerboard grid 7 is set up using the enclosure 2 at step structure 371 to perform binocular testing on the cleaning equipment. There is no need to build a separate binocular vision calibration platform. This allows the sweeping robot to simultaneously complete the depth perception and edge recognition calibration of the binocular camera while verifying the anti-fall function, reducing the number of test platforms 1 and the space occupied.

[0073] Meanwhile, the checkerboard pattern 7 of the stepped enclosure serves as a standardized reference for clearly defined height differences when superimposed on a vertical plane. The binocular camera can calculate the distance to enclosure 2 and the height of step 4 through the corner points of checkerboard pattern 7, verifying its depth perception accuracy for vertical edges and height differences.

[0074] Furthermore, under the same testing environment, the data from the robot vacuum cleaner's cliff sensor trigger (anti-fall) and binocular vision recognition (chessboard pattern on the enclosure) can corroborate each other. For example, whether the height of step 4 recognized by the binocular vision is consistent with the actual height of step 4, and whether the cliff trigger distance matches the safe distance perceived by the binocular vision, provides more comprehensive correlation data for product optimization.

[0075] More specifically, the plurality of enclosures 2 sealing the stepped structure 371 also include a third enclosure opposite to the third test section 33. The third enclosure extends along the height direction and connects to the plurality of test platforms 1, and is covered with a black adhesive layer 9. Similarly, the black adhesive layer 9 has extremely low reflectivity (typically ≤30%). By using the black adhesive layer 9, the stepped structure 371 more easily approximates the light reflection state of the cliff below where there is no ground, allowing the cliff sensor to quickly identify the absence of ground feedback and accurately trigger the fall prevention command.

[0076] In this invention, the sinking height of the stepped structure 371 is 0.08m to 0.13m. Preferably, the depth of the stepped structure 371 is set to 0.1m.

[0077] In this invention, the length of the stepped structure 371 in the direction away from the third test section 33 is 0.5m to 0.55m.

[0078] In this invention, the width of the stepped structure 371 in the direction parallel to the third test section 33 is 0.4m to 0.45m.

[0079] It should be noted that the above three technical features can be selected as one, two, or simultaneously. Specifically, in one embodiment, the above three technical features are simultaneously provided.

[0080] Following the above, before testing, the user places the cleaning equipment at test inlet 36. As the cleaning equipment moves along the first test section 31 from test inlet 36, it encounters step 4, requiring a lifting test at step 4. The lifting test involves testing the cleaning equipment's downward-looking Dtof (Time-of-Flight) sensor and obstacle-crossing wheels. Specifically, it verifies the accuracy of the downward-looking Dtof's recognition of the ground at the test platform 1 inlet, including the accuracy of ground flatness and distance measurements of minor height differences. When the Dtof detects a change in the ground at the inlet (e.g., encountering step 4), it checks whether the obstacle-crossing wheels can adjust their posture in time (e.g., lifting, conforming) to ensure the machine smoothly enters test platform 1 without jamming, bumping, or misjudgment.

[0081] To ensure the accuracy of the test, a white film layer is attached to the first test section 31 at the test inlet 36.

[0082] In one embodiment, the surface of the white film layer is set to a matte or frosted surface. The reflectivity of the matte or frosted white film layer is typically 60% to 80%, which is within the optimal detection range of the downward-looking Dtof (Time-of-Flight) sensor. This reflectivity can stably reflect the infrared signal emitted by the Dtof, ensuring accurate distance measurement and avoiding signal attenuation or interference caused by ground material reflection or excessively dark colors.

[0083] In one embodiment, one edge of the white film layer is flush with the edge of the test inlet 36, and the other edge adjacent to it is flush with one side panel 2.

[0084] To ensure test stability, the overall support of the treadmill testing equipment 100 is made of high-quality aluminum profile 8, and the levelness of the test surface of the test bench 1 is set to ±0.3°.

[0085] To ensure the accuracy of the test, in one embodiment, a shielding area is provided around the outer periphery of the treadmill testing device 100 to block non-testing cleaning equipment, and the distance between the outer edge of the shielding area and the outer side of the treadmill testing device 100 is greater than 2m.

[0086] In this embodiment, no cleaning equipment should be powered on within a 2-meter radius of the treadmill testing equipment 100. Infrared light from sensors such as cameras and DFOF devices not used for testing the cleaning equipment should be avoided from scanning the treadmill testing equipment 100, thereby preventing interference with the cleaning equipment being tested.

[0087] Furthermore, no obstacles should be within 30cm of the cliff at test exit 38, to prevent obstacles from affecting the adjustment of the cleaning equipment's status when it travels to test exit 38.

[0088] In one embodiment, please refer to Figure 1 The treadmill testing equipment 100 also includes a base A, the bottom of which is placed on the ground, and multiple test benches 1 are stacked on the upper surface of the base A. The height of the base A from the ground is typically set to 0.25m to 0.3m.

[0089] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
