Technical Field
[0001] This invention relates to the field of smartwatch testing technology, and more particularly to a smartwatch testing device. Background Technology
[0002] As a portable electronic device integrating health monitoring, information interaction, and other functions, the stability of smartwatches directly affects the user experience and functional reliability. The issue of watches easily falling off is one of the core pain points in current product design and testing. With the rapid development of the smartwatch market, users' requirements for product fit and scenario adaptability are increasing, necessitating standardized testing methods to verify the wearing performance of these products.
[0003] In existing technologies, the stability testing of smartwatches largely relies on subjective judgment through manual trial wearing or static testing using a simple simulated wrist, which has several drawbacks: First, manual trial wearing is greatly affected by individual differences, and the test results lack a unified standard, making it impossible to achieve quantitative judgment and reproduce the risk of falling off under different wearing tightness and activity intensities; Second, the existing detection devices use a single method to simulate the fit, mostly using fixed fitting pressure, which cannot accurately reproduce different fit states such as "too loose, moderate, or too tight" when the user wears the watch, resulting in a large deviation between the testing scenario and the actual usage scenario; Third, there is a lack of simulation of special environments such as sweating. When the human body moves, sweat reduces the friction coefficient between the watch and the skin, significantly increasing the risk of falling off, and existing devices do not effectively combine the sweat environment with dynamic activity detection, resulting in insufficient authenticity of the test results.
[0004] Therefore, a smartwatch detection device needs to be designed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smartwatch testing device. This invention achieves standardized and scenario-based testing of smartwatch wearing stability through integrated dynamic driving, multi-gradient fit adjustment, sweat environment simulation, precise anti-rotation alignment, and quantitative displacement detection functions, overcoming the problems of subjective testing, low scenario reproduction, data distortion, and poor adaptability in existing testing methods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smartwatch testing device includes a mounting frame with a top plate fixedly connected to its upper end. A dynamic drive assembly is mounted on the mounting frame, comprising a servo motor, a main arm, and a secondary arm. The servo motor is mounted on the top plate. Multiple main arms are rotatably connected to the lower end of the top plate. A transmission rod is mounted on the top plate and is connected to the multiple main arms via a transmission assembly. The lower end of each main arm is rotatably connected to a secondary arm, which drives the secondary arm to swing left and right. A hydraulic cylinder is rotatably connected to each main arm, with its extension and retraction ends rotatably connected to the secondary arm. The extension and retraction of the hydraulic cylinder drives the secondary arm to swing up and down. An elliptical block is fixedly connected to the end of the secondary arm furthest from the main arm. During testing, the smartwatch is placed in the middle of the elliptical block. The detection component includes a connecting frame and an infrared sensor. The infrared sensor is mounted on the connecting frame, and the displacement distance of the smartwatch is determined by the electrical signal generated by the infrared sensor.
[0007] Preferably, each of the elliptical blocks is provided with a fit adjustment component. The fit adjustment component includes a rectangular groove, an electromagnet, and an inner support block disposed at the upper and lower ends of the elliptical block. The electromagnet is disposed on the inner wall of the rectangular groove on the side away from the groove opening. The inner support block is slidably connected in the rectangular groove. A permanent magnet adapted to the electromagnet is embedded in the inner side of the inner support block. The outer side of the inner support block is covered with a flexible bonding layer. The adjacent side of the inner support block and the electromagnet is elastically connected by a second spring.
[0008] Preferably, each of the auxiliary arms is equipped with an anti-rotation alignment component, which includes a slide rail, a first cylinder, a mounting bracket, a fixing ring, and a circular ring. The slide rail is mounted on the auxiliary arm, and a slider is slidably connected to the slide rail. The first cylinder is fixedly connected to the slider. The mounting bracket is fixedly connected to the telescopic end of the first cylinder. The fixing ring is fixedly connected to the mounting bracket. The circular ring is located below the fixing ring, and the inner wall of the circular ring has two grooves, the positions of which correspond to the buttons on the edge of the smartwatch.
[0009] Preferably, the device further includes a rotation adjustment assembly, which includes a toothed ring rotatably connected to the lower end of the fixed ring. The lower end of the toothed ring is fixedly connected to a plurality of vertical rods, which are fixedly connected to a circular ring. A mounting plate is mounted on the mounting bracket, and a second cylinder is fixedly connected to the mounting plate. The telescopic end of the second cylinder is fixedly connected to a rack that meshes with the toothed ring. A fixing frame is fixedly connected to the upper end of the fixed ring, and a camera is mounted on the inner top of the fixing frame.
[0010] Preferably, each slide rail is fixedly connected to baffles on both the left and right sides, and the connecting frame is fixedly connected to the corresponding baffles to convert the displacement of the smartwatch into the displacement of the slider.
[0011] Preferably, a sweat simulation component is installed on the front auxiliary arm. The sweat simulation component includes multiple arc-shaped blocks, each of which has multiple water outlets on its front side. A pump body is installed on the auxiliary arm, and the water outlet of the pump body is connected to the multiple arc-shaped blocks through a connecting pipe, which is a flexible hose.
[0012] Preferably, the arc-shaped blocks on the left and right sides are fixedly connected to the elliptical blocks, the arc-shaped blocks on the upper and lower sides are closely attached to the corresponding inner support blocks, two L-shaped plates are symmetrically fixedly connected to the auxiliary arm, and guide rods are fixedly connected to the adjacent sides of the upper and lower arc-shaped blocks. The guide rods pass through the corresponding L-shaped plates, and the upper and lower arc-shaped blocks are elastically connected to the corresponding L-shaped plates by a first spring.
[0013] The present invention has the following beneficial effects: 1. Compared with the prior art, the present invention uses a composite dynamic drive structure composed of a servo motor, main arm, auxiliary arm and hydraulic cylinder to accurately simulate the composite activity trajectory of the human arm swinging left and right and the wrist bending up and down, restore the real force state when the watch is worn, and significantly improve the fit of the detection scene. 2. Compared with the prior art, the present invention, by using the repulsive force adjustment of electromagnet and permanent magnet and the elastic cooperation of second spring, can flexibly realize the simulation of multiple gradient fit of "too loose, moderate, and too tight", accurately reproduce the wearing state of different users, and improve the adaptability of detection scenarios. 3. Compared with the prior art, the present invention integrates a sweat simulation component, which delivers simulated sweat between the watch and the contact surface through a pump body, connecting pipe and water outlet, to reproduce the wearing scenario under sweating conditions, effectively filling the gap of existing devices lacking simulation of special environments, and making the test results closer to actual use needs. 4. Compared with the prior art, the present invention uses a camera to capture images of the watch button positions and automatically recognizes them. It then uses a cylinder-rack-gear ring transmission structure to drive the ring to rotate and adjust, ensuring that the ring groove is precisely aligned with the watch button. This avoids the situation where the watch rotates circumferentially during the testing process, which could lead to poor fit and affect the testing results.
[0014] In summary, this invention features a reasonable structural design and high functional integration. Through the integrated design of dynamic driving, multi-gradient fit adjustment, sweat environment simulation, automatic anti-rotation alignment, and quantitative detection, it effectively solves the problems of subjective testing, low scene reproduction, data distortion, and poor adaptability in existing smartwatch wearing stability testing. The test results are accurate and reliable, and it has strong practicality and promotional value. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0018] Reference Figures 1-5 A smartwatch testing device includes a mounting frame 1, with a top plate 2 fixedly connected to the upper end of the mounting frame 1. A dynamic drive assembly is mounted on the mounting frame 1, comprising a servo motor 3, main arms 4, and auxiliary arms 5. The servo motor 3 is mounted on the top plate 2. The three main arms 4 are triangularly symmetrically distributed, and their upper ends are rotatably connected to the lower end face of the top plate 2 via rotating shafts. A transmission rod 33 is mounted on the top plate 2, and the transmission rod 33 is connected to the multiple main arms 4 via a transmission assembly 12. The transmission assembly 12 consists of four sprockets and a chain. The four sprockets are sleeved on the three main arms and the transmission rod 33. The lower end of the main arm 4 is connected to the auxiliary arm 5 by a hinge. When the main arm 4 rotates around its upper pivot, it can drive the auxiliary arm 5 to swing left and right in sync. The main arm 4 is connected to a hydraulic cylinder 6 by an ear seat. The extension and retraction end of the hydraulic cylinder 6 is connected to the auxiliary arm 5 by a ball joint. The extension and retraction of the hydraulic cylinder 6 drives the auxiliary arm 5 to swing up and down, thereby simulating the complex movement trajectory of the human wrist. An elliptical block 7 is fixedly connected to the end of the auxiliary arm 5 away from the main arm 4. The outline of the elliptical block 7 is adapted to the cross-section of the human wrist. During testing, the smart watch is placed in the middle of the elliptical block 7 so that the watch strap fits the outer surface of the elliptical block 7. The detection component includes a connecting frame 35 and an infrared sensor 36. The infrared sensor 36 is mounted on the connecting frame 35. The detection direction of the infrared sensor 36 is consistent with the length direction of the slide rail 8. The infrared sensor 36 detects the change in distance between itself and the slider in real time, converts the distance change into an electrical signal, and then determines the displacement amount and displacement trend of the smartwatch.
[0019] Each elliptical block 7 is equipped with a fit adjustment component, which includes a rectangular groove 11 at the upper and lower ends of the elliptical block 7, an electromagnet 25, and an inner support block 10. The electromagnet 25 is located on the inner wall of the rectangular groove away from the groove opening. The inner support block 10 is slidably connected to the rectangular groove 11. A permanent magnet adapted to the electromagnet 25 is embedded in the inner side of the inner support block 10. When the electromagnet 25 is energized, it generates a magnetic field force opposite to the same magnetic pole of the permanent magnet. The outer side of the inner support block 10 is covered with a flexible bonding layer. The surface of the flexible bonding layer has an anti-slip texture, which can avoid damage to the watch strap and improve the realism of the fit simulation. The adjacent sides of the inner support block 10 and the electromagnet 25 are elastically connected by a second spring 32. The second spring 32 is sleeved on the outside of the electromagnet 25. In the initial state, the second spring 32 is in a naturally extended state, so that the inner support block 10 is kept in the initial contracted position.
[0020] Each auxiliary arm 5 is equipped with an anti-rotation alignment component, which includes a slide rail 8, a first cylinder 9, a mounting bracket 14, a fixing ring 15, and a circular ring 18. The slide rail 8 is mounted on the auxiliary arm 5, and a slider is slidably connected to the slide rail 8. The first cylinder 9 is fixedly connected to the slider. The mounting bracket 14 is fixedly connected to the telescopic end of the first cylinder 9. The fixing ring 15 is fixedly connected to the mounting bracket 14. The circular ring 18 is located below the fixing ring 15. The inner wall of the circular ring 18 has two grooves 19, and the positions of the two grooves 19 correspond to the buttons on the edge of the smartwatch. Each slide rail 8 has baffles 34 fixedly connected to its left and right sides, and a connecting bracket 35 is fixedly connected to the corresponding baffles 34 to convert the displacement of the smartwatch into the displacement of the slider.
[0021] The system also includes a rotation adjustment assembly, which includes a toothed ring 16 rotatably connected to the lower end of the fixed ring 15. Multiple vertical rods 17 are fixedly connected to the lower end of the toothed ring 16 and are fixedly connected to the circular ring 18. A mounting plate 22 is mounted on the mounting bracket 14, and a second cylinder 23 is fixedly connected to the mounting plate 22. A rack 24 meshing with the toothed ring 16 is fixedly connected to the telescopic end of the second cylinder 23. The tooth pitch of the rack 24 is perfectly matched to the tooth pitch of the toothed ring 16. The telescopic movement of the second cylinder 23 can drive the rack 24 to move linearly, thereby driving the toothed ring 16 to rotate. A fixed frame 20 is fixedly connected to the upper end of the fixed ring 15. A camera 21 is mounted on the inner top of the fixed frame 20. The camera 21 shoots vertically downwards, and its shooting range covers the circular ring 18 and the smartwatch button area below it, used to collect images of the smartwatch button positions. All components in the rotation adjustment assembly and the anti-rotation alignment assembly are made of plastic, reducing the impact of the weight of each component on the detection.
[0022] The auxiliary arm 5 located at the front is equipped with a sweat simulation component, which includes multiple arc-shaped blocks 26. Each arc-shaped block 26 has multiple water outlets 28 on its front side. A pump body 13 is installed on the auxiliary arm 5. The inlet end of the pump body 13 is connected to a storage tank (not shown in the figure), which contains a saline solution simulating the composition of human sweat. The outlet end of the pump body 13 is connected to the multiple arc-shaped blocks 26 through a connecting pipe 27. The connecting pipe 27 is a flexible tube that can accommodate the swinging of the auxiliary arm 5 and the displacement of the arc-shaped blocks 26. The arc-shaped blocks 26 located on the left and right sides are fixedly connected to the elliptical blocks 7, and the upper and lower arc-shaped blocks 26 are fixedly connected to the elliptical blocks 7. The arc-shaped block 26 on the side is closely attached to the corresponding inner support block 10. Two L-shaped plates 29 are symmetrically fixedly connected to the auxiliary arm 5. Guide rods 30 are fixedly connected to the adjacent sides of the upper and lower arc-shaped blocks 26. The guide rods 30 pass through the corresponding L-shaped plates 29, allowing the arc-shaped blocks 26 to move axially along the guide rods 30. The upper and lower arc-shaped blocks 26 and the corresponding L-shaped plates 29 are elastically connected by the first spring 31. The first spring 31 provides a preload force to the upper and lower arc-shaped blocks 26 toward the inner support block 10, ensuring that the arc-shaped blocks 26 are always tightly attached to the inner support block 10 and move synchronously with the extension and retraction of the inner support block 10.
[0023] The functional principle of this invention can be explained through the following operation: In the initial testing stage, three smartwatches of identical specifications are respectively placed in the middle of the three elliptical blocks 7, ensuring that the watch strap is tightly fitted to the flexible adhesive layer on the outside of the elliptical block 7 and the inner support block 10. The fit adjustment stage has specifically set parameters: the fit adjustment components of the left and front elliptical blocks 7 are synchronized. By controlling the current intensity of the electromagnet 25, the inner support block 10 is kept at the same extension range under the combined action of the repulsive force between the electromagnet 25 and the permanent magnet, and the elastic tension of the second spring 32, simulating a "moderate" wearing fit. The current of the electromagnet 25 on the right elliptical block 7 is adjusted to change the extension state of the inner support block 10, simulating a "too loose" or "too tight" fit, providing variable conditions for subsequent fit comparison testing. Simultaneously, simulated sweat is injected into the pump body 13 corresponding to the front elliptical block 7, ensuring smooth communication between the connecting tube 27 and each arc-shaped block 26. The sweat simulation components of the left and right elliptical blocks 7 remain closed.
[0024] The anti-rotation alignment operation is performed synchronously on the anti-rotation alignment components corresponding to the three elliptical blocks 7: The camera 21 at the top inside the fixing frame 20 is activated to take a picture of the button position on the edge of the smartwatch. The image is analyzed by the built-in image recognition system to determine whether the groove 19 on the ring 18 is on the same side as the watch button. If the groove 19 is not on the same side as the watch button, the second cylinder 23 is immediately controlled to retract, driving the rack 24 to move linearly. The rack 24 meshes with the gear ring 16, driving the gear ring 16 to drive the vertical rod 17 and the ring 18 to rotate 180 degrees synchronously until the groove 19 is precisely aligned with the watch button. If the image recognition result shows that the groove 19 and the watch button are on the same side, the second cylinder 23 remains stationary and does not work. Once the position of the ring 18 is determined, the first cylinder 9 is controlled to retract, causing the mounting bracket 14, the fixing ring 15, and the ring 18 to move down synchronously, so that the ring 18 is precisely fitted onto the outside of the watch. The watch is circumferentially fixed by the engagement of the groove 19 with the watch button. At the same time, the linkage between the watch and the slider is established, laying the foundation for subsequent displacement transmission. This avoids data distortion caused by the watch rotating or disengaging from the linkage during the testing process, ensuring the fairness and accuracy of the comparative test.
[0025] In the dynamic driving stage, the servo motor 3 on the top plate 2 is started. The servo motor 3 drives the three main arms 4 to rotate synchronously through the transmission rod 33 and the transmission component 12, realizing the "arm swinging left and right" action. At the same time, the three hydraulic cylinders 6 are controlled to extend and retract synchronously, pushing the auxiliary arm 5 to swing up and down relative to the main arm 4, simulating the composite dynamic trajectory of "wrist bending up and down". The movement frequency and bending angle of the three auxiliary arms 5 are strictly kept consistent, completely eliminating the interference of motion parameter differences on the detection results.
[0026] During the testing process, the sweat simulation component corresponding to the front elliptical block 7 is activated simultaneously: the simulated sweat in the pump body 13 is delivered to each arc-shaped block 26 through the connecting pipe 27, and evenly sprayed onto the contact surface of the watch, inner support block 10, and elliptical block 7 through the outlet 28, reducing the friction coefficient of the contact surface and realistically reproducing the wearing scenario under sweating conditions; the arc-shaped blocks 26 on the upper and lower sides are tightly attached to the inner support block 10 under the elastic action of the first spring 31, and can move synchronously with the extension and retraction state of the inner support block 10. The guide rod 30 and the L-shaped plate 29 cooperate to ensure that the arc-shaped blocks 26 move smoothly, ensuring that the sweat spray range always covers the contact surface. The left and right elliptical blocks 7 only follow the dynamic drive component to simulate movement.
[0027] In the displacement detection stage, the detection components corresponding to the three elliptical blocks 7 collect data in real time: the connecting frame 35 is fixed on the baffles 34 on both sides of the slide rail 8, and the infrared sensor 36 is installed on the connecting frame 35. When the watch becomes loose or displaced during dynamic activities, the mounting frame 14, the first cylinder 9, and the slider will move synchronously along the slide rail 8 through the outer ring 18. The infrared sensor 36 generates an electrical signal by sensing the displacement of the slider, accurately converting the displacement of the smartwatch into the displacement of the slider, thus achieving quantitative detection. After the detection is completed, by comparing the data of the infrared sensor 36 corresponding to the left and right elliptical blocks 7, the displacement difference of the watch under the same dynamic activities under different fit can be clearly analyzed, clarifying the impact of fit on wearing stability; by comparing the detection data of the left and front elliptical blocks 7, the impact of the sweat environment on the wearing stability of the watch under the same fit and dynamic activity conditions can be accurately determined. Finally, through the two sets of comparison results, the wearing stability performance of the smartwatch can be comprehensively and objectively quantified.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
