Abstract
Description
Technical Field
[0001] This invention belongs to the field of door and window testing technology, specifically relating to a door and window hardware motion simulation testing system with adaptive passive following and omnidirectional adjustment functions. Background Technology
[0002] Motion mechanics simulation testing of doors, windows, and their associated hardware is a core step in evaluating product reliability and safety. To improve the iterative advancement of hardware structural components and safety parts, the industry typically uses mechanized methods to simulate daily opening, closing, and tilting movements. By collecting mechanical parameters during these movements, objective data is provided to support product design optimization. Currently, automated equipment used for motion simulation testing of door and window hardware mainly relies on two technical approaches: one is to use multi-degree-of-freedom industrial robots to reproduce the motion trajectory of doors and windows through teach programming; the other is to use actuators with preset rigid trajectories, driven by rigid components such as cylinders and connecting rods to simulate door and window actions.
[0003] However, existing equipment uses pre-set rigid motion trajectories. However, during the later stages of long-term fatigue testing, door and window hardware may experience slight deviations in their actual motion trajectory due to wear, deformation, and other factors. Since existing equipment cannot detect and follow this deviation, its end effector forces the door and window sash to move along the original trajectory, resulting in abnormal parasitic stress at the connection between the handle and the hardware. This additional stress severely distorts the test data and fails to accurately reflect the natural fatigue life of the hardware. In real doors and windows, especially when the sash sags due to installation errors or hardware wear, the plane of rotation is not strictly vertical but rather exhibits a slight angular wobble.
[0004] Furthermore, the actuators of existing equipment can typically only provide horizontal following within a fixed plane, and cannot adaptively compensate for the angular displacement components generated during the opening and closing of doors and windows. When there is an angular deviation between the movement trajectory of the door or window and the movement plane set by the equipment, forced lateral stress will also be generated at the handle connection, further exacerbating the distortion of the test results.
[0005] Meanwhile, tilting inwards is a complex motion with a spatial tilt angle. As the door and window sash tilts inwards, the movement trajectory of its handle exhibits nonlinear displacement components in both the horizontal and vertical dimensions. Traditional rigid linkage mechanisms, limited by their planar kinematic pairs, struggle to reproduce this spatial motion trajectory. While industrial robots can simulate this trajectory, as mentioned earlier, their rigid position control cannot adapt to trajectory changes caused by wear on the hardware, easily leading to abnormal mechanical damage during testing or rendering the test data unusable.
[0006] To address the aforementioned issues, this application proposes a motion simulation testing system for door and window hardware that can eliminate the forced trajectory constraints on door and window sashes, adaptively compensate for the angular sway of door and window sashes, be compatible with both casement and tilt-and-turn modes, and be easy to debug. This system features adaptive passive following and omnidirectional adjustment functions. Summary of the Invention
[0007] The purpose of this invention is to address the above-mentioned problems by providing a motion simulation testing system for door and window hardware with strong compatibility, good trajectory constraint effect, and adaptive passive following and omnidirectional adjustment functions.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a door and window hardware motion simulation test system with adaptive passive following and universal adjustment functions, comprising a support frame, a non-powered horizontal guide rail movably mounted on the support frame, and a freely sliding sliding mounting seat mounted on the non-powered horizontal guide rail; a swing drive motor is mounted on the support frame to drive the non-powered horizontal guide rail to swing relative to it, and a rotary drive motor is mounted on the sliding mounting seat. The output shaft of the rotary drive motor is connected to the handle operating clamp through a universal transmission assembly, allowing an angle between the two axes while transmitting rotational torque; when the opening and closing action of the door and window sash causes the handle to produce horizontal displacement, the sliding mounting seat passively slides on the non-powered horizontal guide rail following the displacement.
[0009] The core architecture of this system is a two-layer adaptive decoupling mechanism. The first layer of decoupling is achieved by a non-powered horizontal guide rail and a sliding mounting base: when the door or window sash opens or closes, the movement trajectory of the handle is not a simple arc; its radial displacement component relative to the door frame is absorbed by the free sliding of the sliding mounting base, thus completely eliminating the forced trajectory constraint of traditional rigid testing equipment on the door or window sash. The second layer of decoupling is achieved by a swing drive motor: due to installation errors or wear of hardware, the rotation plane of a real door or window may have a slight angular wobble. The swing motor drives the entire non-powered horizontal guide rail to swing adaptively with the wobble direction of the door or window sash, ensuring that the passive sliding direction always matches the actual displacement direction of the door or window sash. The universal transmission component provides a third dimension of flexible compensation, allowing a spatial angle between the output shaft of the rotary drive motor and the axis of the handle operating fixture, providing kinematic margin for subsequent complex movements such as tilting inward.
[0010] The three decoupling mechanisms described above work together to enable the end clamp of the test system to act like a zero-stiffness follower, transmitting only rotational operating torque without adding any abnormal pulling, pushing, or bending moments to the door or window sash.
[0011] In the aforementioned door and window hardware motion simulation testing system with adaptive passive following and omnidirectional adjustment functions, a multi-dimensional positioning adjustment device is installed on the support frame. This device includes a horizontal adjustment mechanism and a vertical adjustment mechanism, which are used to drive the unpowered horizontal guide rail and its mounted components to move horizontally along the Y-axis and rise and fall along the Z-axis, respectively. The multi-dimensional positioning adjustment device enables rapid physical alignment between the testing system and doors and windows of different specifications. In traditional solutions, changing the door or window under test often requires reprogramming or replacing the tooling fixtures. This solution, however, uses the Y-axis horizontal adjustment mechanism and the Z-axis vertical lifting mechanism to adjust the spatial position of the entire follow-up execution unit, equipped with a rotary drive motor, omnidirectional transmission components, and handle operating fixture, as a whole, quickly aligning it with the handle of the door or window under test, eliminating the need for cumbersome software parameter settings.
[0012] The swing drive motor, the rotary drive motor, and the multi-dimensional positioning adjustment device together constitute a complete motion control system from coarse positioning to fine following: the adjustment device is responsible for static alignment before testing, while the swing drive motor and the unpowered horizontal guide rail are responsible for dynamic following during testing.
[0013] In the aforementioned door and window hardware motion simulation testing system with adaptive passive following and omnidirectional adjustment functions, the horizontal adjustment mechanism includes an adjustment frame slidably mounted on a slide rail, with the adjustment frame and slide rail locked in their Y-axis orientation by a screw. The vertical adjustment mechanism includes a hand-cranked screw lifting structure fixedly mounted on the adjustment frame, which drives the unpowered horizontal guide rail and all components mounted on it to move up and down relative to the adjustment frame along the Z-axis. Both the horizontal and vertical adjustment schemes are purely mechanical structures, independent of any electrical drive or control program, resulting in high structural reliability and immunity to electromagnetic interference or software failures. Furthermore, operation is intuitive and simple; operators only need to crank a handle to complete the alignment, minimizing the learning curve. The locked structure has sufficient rigidity to ensure that positional drift does not occur due to vibration during long-term fatigue testing, ensuring consistent test conditions.
[0014] In the aforementioned door and window hardware motion simulation test system with adaptive passive following and omnidirectional adjustment functions, the sliding mounting seat is coupled to a non-powered horizontal guide rail via a low-friction rolling bearing. When the door or window sash opens and closes, the horizontal force transmitted from the handle to the handle operating clamp is usually small. If the frictional resistance of the guide rail pair is too high, the sliding mounting seat cannot respond to displacement changes in time, resulting in jamming or lag. This introduces additional constraint force at the handle connection, undermining the design intent of adaptive following. In this solution, the rolling bearing converts sliding friction into rolling friction, reducing both starting friction and dynamic friction to extremely low levels. This ensures that the sliding mounting seat has high follow-up sensitivity to the displacement of the door or window sash, truly achieving zero-interference following.
[0015] In the aforementioned door and window hardware motion simulation test system with adaptive passive following and omnidirectional adjustment functions, the handle operating fixture or its transmission chain integrates an angle sensor for detecting the handle rotation angle, a torque sensor for detecting the output torque of the rotary drive motor, and a tension sensor for detecting the tension and pressure during the opening and closing of the door and window; the system also includes a dynamic drop displacement sensor for detecting the drop displacement of the door and window sash caused by fatigue deformation of the hardware.
[0016] The aforementioned sensor configuration covers three core monitoring dimensions for door and window hardware motion simulation. The first dimension is kinematic parameters: angle sensors record the handle rotation angle to verify whether the opening and closing action reaches the designed stroke and to monitor for stroke attenuation during fatigue testing. The second dimension is mechanical parameters: torque and tension sensors monitor operating torque and tensile / compressive forces during opening and closing, respectively. The former reflects the friction and wear state of the hardware transmission system, while the latter reflects the resistance to lock release and changes in sealing strip reaction force. The third dimension is fatigue degradation parameters: dynamic drop displacement sensors are specifically used to capture the amount of sash drop caused by hardware, especially hinge wear or plastic deformation. This is a key indicator for measuring the long-term load-bearing capacity and structural integrity of door and window hardware, and a monitoring gap generally overlooked by traditional testing equipment. In addition, the swing drive motor is also equipped with corresponding angle or torque sensors to achieve real-time motion monitoring and ensure stable feedback control.
[0017] The aforementioned door and window hardware motion simulation testing system with adaptive passive following and omnidirectional adjustment functions also includes a central processing controller and a display terminal. The central processing controller receives detection signals from each sensor, dynamically plots the mechanical and motion curves during the test process on the display terminal, and issues an alarm and stops the system when any sensor value exceeds a preset peak value. The central processing controller not only handles data acquisition and visualization but also incorporates anomaly detection and protection logic. In actual testing, hardware failure often manifests as a sudden increase in torque, abnormal fluctuations in tensile force, or accelerated growth in downward displacement. By comparing sensor values with preset peak thresholds in real time, the controller can stop the system in time before the hardware breaks or is severely damaged, protecting the testing equipment from accidental impacts and fully recording key data of the failure process, providing a basis for subsequent failure analysis. The dynamic curve plotting function allows testers to intuitively grasp the performance degradation trend of the hardware, rather than simply obtaining a binary judgment result of pass or fail.
[0018] In the aforementioned door and window hardware motion simulation test system with adaptive passive following and omnidirectional adjustment functions, this system has a casement test mode and an inward tilt test mode.
[0019] In the casement test mode, the rotary drive motor drives the handle to rotate through the universal transmission assembly. The radial displacement generated during the opening of the door and window sash is compensated by the passive sliding of the sliding mounting base on the unpowered horizontal guide rail. The kinematic nature of the casement mode is planar rotation. The motion of the door and window sash handle can be decomposed into tangential displacement and radial displacement around the hinge axis. The radial displacement component is passively absorbed by the unpowered horizontal guide rail. The system only needs to actively provide the handle rotation torque.
[0020] In the inward tilt test mode, when the handle is in the vertically upward position, the rotary drive motor first performs an axial pull-out action. After passing the tension critical point, it reverses and outputs thrust, using the spatial rotation characteristics of the universal joint to guide the door / window sash to tilt inward, thus simulating the inward tilting action. The kinematic essence of the inward tilt mode is a spatial composite motion. The door / window sash tilts inward around the bottom hinge, and the handle end generates an arc-shaped displacement in the vertical plane, while simultaneously generating a displacement component inward in the horizontal plane. This solution utilizes the spatial rotation characteristics of the universal joint to adapt to this composite motion: the rotary drive motor first applies axial tension through the universal joint, causing the door / window sash to overcome the resistance of the sealing strip and detach from the frame; after passing the critical point, the motor reverses and outputs thrust. When transmitting thrust, the universal joint allows the handle end to change its posture with the spatial tilt of the door / window sash, thus completely replicating the inward tilting action without adding additional mechanical degrees of freedom, relying solely on the inherent flexibility of the universal joint in the transmission chain.
[0021] In the aforementioned door and window hardware motion simulation testing system with adaptive passive following and omnidirectional adjustment functions, the pull-out action and reverse twisting in the tilt-in test mode are controlled by a central processing controller through program control. The pull-out, critical judgment, and reverse push-in timing of the tilt-in action are programmed by the central processing controller, and its control logic can be flexibly adjusted according to the characteristics of different door and window hardware. In practical applications, the rebound force of the sealing strip and the critical force of the locking point disengagement vary among different specifications of doors and windows. By setting the pull-out displacement, critical force threshold, and reverse push-in curve through software parameters, it can be adapted to various products without replacing any mechanical hardware, thus balancing the fidelity of motion simulation and the versatility of the equipment in various testing scenarios.
[0022] In the aforementioned door and window hardware motion simulation test system with adaptive passive following and universal adjustment functions, the universal transmission component is a universal joint, which not only meets the compensation requirements for axial deviation in the casement mode, but also provides kinematic margin for the spatial angle changes caused by the tilting of the door and window sash in the tilt-in mode.
[0023] In the aforementioned door and window hardware motion simulation test system with adaptive passive following and omnidirectional adjustment functions, the handle operating fixture is a replaceable end clamp. During actual testing, the handles come in various shapes, including fork-type, knob-type, and lever-type, with significant differences in the cross-sectional shape and size of their gripping parts. Through a combination of standardized fixture interfaces and customized clamping surfaces, operators only need to replace the end clamp to switch between different handle types without adjusting or replacing the upstream omnidirectional transmission components and drive motor, maximizing the system's versatility and changeover efficiency.
[0024] Compared with existing technologies, the advantages of this invention are as follows: By using passive sliding, swing following, and universal compensation three-layer adaptive decoupling, the forced trajectory constraints and parasitic stress are completely eliminated, and the test data truly restores the physical state of the doors and windows; a multi-dimensional manual adjustment device is used for rapid physical alignment, and no software programming is required to replace the doors and windows under test, thus shortening the debugging time; by utilizing the spatial rotation characteristics of the universal joint, a single device can be compatible with fatigue simulation testing of two complex movements: casement and tilt-and-turn; the swing drive motor drives the guide rail to swing as a whole, which solves the problem of forced lateral constraints caused by the traditional equipment when the rotating plane of the door and window sash wobbles due to wear or installation errors.

[0029] Figure 5 This is an operation flowchart of the present invention;
[0030] In the figure, the components are: support frame 1, adjustment frame 11, slide rail 12, screw 13, hand crank lifting structure 14, non-powered horizontal guide rail 2, sliding mounting base 3, swing drive motor 4, rotary drive motor 5, universal transmission assembly 6, handle operating fixture 7, central processing controller 8, and display terminal 9. Detailed Implementation
[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0032] Example 1
[0033] like Figure 1-5As shown, this embodiment is used for repeated opening and closing fatigue testing of standard casement window hardware, simulating the opening → closing process. First, the door / window sample to be tested is fixed to the adjustment frame 11 of the support frame 1. The operator uses the horizontal adjustment mechanism of the multi-dimensional positioning adjustment device and the hand-cranked screw lifting structure 14 to quickly and physically align the handle operating clamp 7 with the door / window handle, and uses the multi-point screw 13 to lock the Y-axis position of the adjustment frame 11 on the slide rail 12. An end clamp adapted to the shape of the handle to be tested is selected and reliably connected to the handle.
[0034] After activating the hinged test mode, the rotary drive motor 5 drives the handle to rotate via the universal transmission assembly 6, simulating the action of a human hand opening a door or window. When the door or window sash rotates around the hinge axis, the radial displacement generated at the handle end pushes the sliding mounting base 3 to passively slide backward on the unpowered horizontal guide rail 2; when closing the door or window sash, the door or window sash returns to its original position, and the sliding mounting base 3 passively slides forward accordingly. Throughout the process, the swing drive motor 4 is in a follow-up release state, sensing any slight angular sway that the door or window sash may have in real time and driving the unpowered horizontal guide rail 2 to swing accordingly, ensuring that the passive sliding direction is always consistent with the actual displacement direction of the door or window sash.
[0035] The central processing controller 8 collects signals from the angle sensor, torque sensor, and tension sensor throughout the process, dynamically plots the operating torque-angle curve and tension / compression change curve on the display terminal 9, and automatically cycles at a set frequency until the specified number of cycles is completed or the sensor values exceed the limits and the machine stops.
[0036] Example 2
[0037] The structure, principle, and steps of this embodiment are similar to those of Embodiment 1. It achieves fatigue testing of the inward opening and inward tilting composite mode through mode switching, reflecting the functional complexity of the system and realizing a complete simulation of opening → closing → tilting → closing.
[0038] Specifically, after completing a set of swing test cycles in Example 1, the door and window sashes are in a closed and locked state. No hardware replacement is required. The operator switches to the inward-opening and inward-tilting composite test mode on the central processing controller 8. At this time, the test program adds an inward-tilting action to the locked state, based on the completed inward swing cycle: the rotary drive motor 5 of the handle operating fixture 7 drives the handle to continue rotating to the 180-degree inward-tilting position. Simultaneously, the swing drive motor 4 drives the unpowered horizontal guide rail 2 to perform a slight fan-shaped swing. The universal transmission component 6 of the handle operating fixture 7 then sways, and the sliding mounting base 3 passively slides slightly on the unpowered horizontal guide rail 2, thereby causing the door and window sashes to perform the inward-tilting action. During the inward-tilting process, after the door and window sashes cross the gravity equilibrium point, the system's tension is converted into thrust, ensuring smooth power transmission and effectively preventing the mechanism from jamming.
[0039] During the aforementioned inward tilting action, when the tension sensor detects a tension or force exceeding a preset critical threshold, the central processing controller 8 determines that the door / window sash has detached from the frame sealing surface and then controls the rotary drive motor 5 to reverse and output thrust. The door / window sash tilts inward around the bottom hinge, and the spatial movement trajectory of the handle end generates nonlinear displacement components in both the horizontal and vertical directions. The universal transmission component 6 utilizes its own spatial rotation characteristics to allow the handle operating clamp 7 to change its posture as the door / window sash tilts while transmitting thrust. The sliding mounting base 3 passively compensates for the horizontal displacement component on the unpowered horizontal guide rail 2, thereby completely reproducing the inward tilting action and achieving seamless connection testing of the two complex actions of opening and tilting.
[0040] Example 3
[0041] This embodiment uses a swing drive motor 4 to simulate the tilting of the rotation plane caused by improper installation or long-term use of the hinges of doors and windows.
[0042] In actual engineering projects, due to installation errors, the rotation plane of some doors and windows is not perfectly vertical, but has a slight tilt. After long-term operation, uneven wear of the hinges will further aggravate the tilt. To evaluate the durability of the hardware under such non-ideal working conditions, before the test begins, the central processing controller 8 presets a fixed yaw angle to the swing drive motor 4, so that the unpowered horizontal guide rail 2 forms a slight angle with the theoretical horizontal plane.
[0043] In subsequent test cycles of opening or tilting inwards, the swing drive motor 4 maintains a constant yaw angle, simulating the rotation of the door / window sash within an inclined plane. The sliding mounting base 3 passively slides on the inclined, unpowered horizontal guide rail 2, and sensors record the changes in operating torque, tension / compression, and downward displacement under this skewed condition. By comparing the test data from standard and skewed conditions, the tolerance of hardware to installation errors and structural deformation can be quantitatively assessed, providing a reliability reference for product design under extreme conditions.
[0044] Example 4
[0045] This embodiment demonstrates the collaborative operation of the dynamic fall displacement sensor and the central processing controller 8, as well as the early warning logic based on the fall trend.
[0046] Before the test begins, a dynamic drop displacement sensor is installed at the bottom edge of the door / window sash. Its measurement reference is fixed to the support frame 1 or the ground, and the measuring end points towards the bottom edge of the door / window sash. In each cycle of the casement or tilt-in fatigue test, the central processing controller 8 triggers a drop displacement sampling when the door / window sash is in the closed position, and records the height deviation of the bottom edge of the door / window sash relative to the initial position at that moment.
[0047] As the number of test cycles increases, the central processing controller 8 dynamically plots a drop-cycle trend curve on the display terminal 9. When the central processing controller 8 detects that the rate of increase in drop exceeds a preset slope threshold, even if the total drop has not yet reached the limit value, the system will issue a yellow warning signal to remind the tester to pay attention to the accelerated degradation trend of the hardware. When the absolute value of the drop exceeds a preset peak value, the system issues a red alarm and automatically shuts down, fully retaining all data before and after the failure.
[0048] Example 5
[0049] This embodiment demonstrates the replaceability and adaptability of the handle operating fixture 7, and shows that the system has good versatility in multi-variety testing scenarios.
[0050] For fork-type handles, an end clamp with a rectangular groove on the inner wall matching the cross-section of the fork is selected and fastened to the standard interface of the handle operation clamp 7 by bolts; for knob-type handles, a cylindrical clamping head with anti-slip texture on the inner hole is replaced; for lever-type handles, a claw-type end clamp with an arc-shaped clamping surface and an adjustable clamping screw is replaced.
[0051] All end clamps use a unified quick-change interface, and the time to replace a single clamp is no more than one minute. After replacement, there is no need to recalibrate the coaxiality of the handle operating clamp 7 and the universal transmission assembly 6, thus maintaining the system's ability to quickly change between multiple test tasks.
[0052] Example 6
[0053] This embodiment is mainly applied to the testing of other types of opening and closing structures. First, the hardware of the cabinet door or sliding door to be tested is installed on the simulated cabinet frame. The multi-dimensional positioning adjustment device is adjusted so that the handle operating clamp 7 is aligned with the cabinet door handle or sliding door handle.
[0054] For hinged cabinet doors, the testing process is similar to that in Example 1. The rotary drive motor 5 drives the handle through the universal transmission assembly 6, and the sliding mounting base 3 passively follows the displacement generated by the opening and closing of the cabinet door on the unpowered horizontal guide rail 2.
[0055] For the sliding door system, the control mode of the rotary drive motor 5 is adjusted to linear analog mode. The rotary drive motor 5 does not output continuous rotational motion, but under the program control of the central processing controller 8, it swings back and forth in a set angle increment, and drives the sliding door to move back and forth along the guide rail through the universal transmission assembly 6 and the handle operating clamp 7.
[0056] At this point, the passive sliding function of the unpowered horizontal guide rail 2 compensates for the slight lateral offset that may occur during the movement of the sliding door, while the universal drive assembly 6 absorbs the angular deviation caused by the transmission axis not being completely parallel to the direction of movement of the sliding door due to installation errors. Torque and tension sensors monitor the moving resistance and operating force, respectively, while the dynamic drop displacement sensor monitors the sinking trend of the sliding door panel, thus comprehensively evaluating the durability of the sliding door hardware system.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
