Description

Technical Field

[0001] This invention relates to the field of smart door lock testing technology, specifically to a device and method for testing the static tensile force and torsional strength of a smart door lock handle. Background Technology

[0002] The static tensile force and torsional resistance tests of smart door lock handles must be conducted in accordance with the test methods specified in clauses 5.4.9 and 5.4.17 of GB 21556-2008. Currently, the laboratory conducts static tensile force and torque tests on different test devices.

[0003] Currently, the smart door lock is mounted on a tensile testing machine using a clamp. A specified tension is applied to the handle and held for 30 seconds. After unloading, the handle is checked for deformation and whether its operation is normal. Next, the smart door lock is mounted on a test bench using another set of clamps, so that the handle is in the extreme state of locking or opening. A specified torque is applied to the handle using a torque wrench and held for 30 seconds. After unloading, the handle is checked for deformation and whether its operation is normal.

[0004] The above process requires disassembling and assembling the smart lock at least twice. The assembly process is cumbersome and inefficient. Moreover, the applied load lacks monitoring, which affects the reliability of the results. Based on the problems of low efficiency and lack of load detection in the current test method, this application proposes a test device and method for static tensile force and torsion resistance of smart lock handles. Summary of the Invention

[0010] The load application assembly includes a mounting bracket, a transfer platform, a splined shaft, a rotary disk, a static tension application module, and a torque application module. The mounting bracket is located beside the positioning assembly, and the transfer platform is mounted on the mounting bracket. The splined shaft has a working end and a connecting end. The working end of the splined shaft is equipped with a connecting fixture, and the connecting fixture has a connecting groove for the smart lock handle to pass through. The rotary disk is located on the transfer platform, and the connecting end of the splined shaft is key-connected to the rotary disk and passes through the transfer platform. The splined shaft can move axially under the drive of the static tension application module to apply static tension to the smart lock handle, and the rotary disk can drive the splined shaft to rotate under the drive of the torque application module to apply torque to the smart lock handle.

[0011] According to a specific embodiment of the present invention, the transfer platform is provided with a transmission module connected to the rotating disk.

One end of the torque sensor is connected to the output shaft of the servo motor through a first coupling, and the other end of the torque sensor is connected to the transmission module through a second coupling.

[0012] Furthermore, the transmission module is a gear transmission module, which includes a drive gear and a driven gear ring that mesh with each other. The drive gear is driven and connected to the second coupling, and the driven gear ring is fixedly connected to the rotating disk.

[0013] According to a specific embodiment of the present invention, the static tension application module includes a guide wheel, a steel wire rope and a counterweight. The guide wheel is rotatably mounted on the mounting frame. One end of the steel wire rope is connected to the counterweight, and the other end of the steel wire rope passes around the guide wheel and is connected to the spline shaft through a rotary connector module.

[0014] Furthermore, the rotary connector module includes a connector body, a retaining ring, and a connecting post. The connector body is slidably mounted on the mounting bracket and connected to the wire rope, while the connecting post is mounted on the spline shaft. The connector body, retaining ring, and connecting post are connected together in sequence. The connecting post is stepped, and the retaining ring is fitted onto the connecting post and rotates with it.

[0015] Furthermore, the static tension application module further includes a movable pusher, on which the connector body is slidably mounted; wherein, a stop boss is provided on the side of the movable pusher near the transfer platform on the connector body, and when the movable pusher moves toward the transfer platform under the drive of the push-pull module, it abuts against the stop boss and can pull the connector body to release the static tension applied to the spline shaft by the counterweight through the connector body.

[0016] Furthermore, the rotary connector module further includes a connecting disc and a tension sensor, which are sequentially arranged between the retaining ring and the stop boss. The tension sensor is used to detect the applied static tension value.

[0017] According to a specific embodiment of the present invention, the positioning component includes a horizontal slide rail and a test push plate.

[0035] To better understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description with reference to embodiments in order to provide a thorough understanding of the present invention; however, it should be understood that the following embodiments and detailed descriptions are for illustrative purposes only and do not limit the scope of protection of the present invention.

[0036] The intelligent door lock handle static tensile force and torsional resistance testing device of the present invention is as follows: Figure 1 As shown, the device includes a fixing fixture 10, a positioning component 20, and a load application component 30. The fixing fixture 10 is mainly used to fix the smart lock, and the positioning component 20 is mainly used to position the fixing fixture 10. The fixing fixture 10 has a placement position for fixing the smart lock, which is preferably accommodating different types of locks to achieve versatility and compatibility in the test. The load application component 30 is located beside the positioning component 20 and is mainly used to apply static tension and torque to the smart lock fixed by the fixing fixture 10.

[0037] like Figures 2-4 As shown, the load application assembly 30 includes a mounting bracket 31, a transfer platform 32, a spline shaft 33, a rotary disk 34, a static tension application module 35, and a torque application module 36.

[0038] The mounting bracket 31 is located beside the positioning component 20, specifically on the front side of the smart door lock installed on the fixing fixture 10; the transfer platform 32 is installed on the mounting bracket 31, specifically in a vertical form. The transfer platform 32 is mainly used to provide structural space for force transmission for the static tension application module 35 and the torque application module 36.

[0039] The splined shaft 33 has a working end and a connecting end. The working end of the splined shaft 33 is provided with a connecting fixture 37. The connecting fixture 37 has a connecting groove 371 for the smart lock handle to pass through. The connecting groove 371 is, for example, a square groove. The size of the connecting groove 371 exceeds the outer contour of the smart lock handle to allow the smart lock handle to pass through the connecting groove 371 and contact and engage with the groove wall of the connecting groove 371. Thus, the connecting fixture 37 drives the smart lock handle to be pulled or twisted. Furthermore, the connecting fixture 37 is preferably installed on the splined shaft 33 in a detachable manner, for example, by means of a quick-release pin 372.

[0040] The rotating disk 34 is mounted on the transfer platform 32, specifically on the side of the transfer platform 32 facing the fixed fixture 10. The connecting end of the spline shaft 33 is keyed to the rotating disk 34 and passes through the transfer platform 32. The keyed connection forms two non-interfering transmission connections between the spline shaft 33 and the rotating disk 34. On the one hand, it realizes the sliding connection between the spline shaft 33 and the rotating disk 34. On the other hand, it realizes the synchronous rotational connection between the spline shaft 33 and the rotating disk 34. This allows the spline shaft 33 to move axially under the drive of the static tension application module 35 to apply static tension to the smart door lock handle. It also allows the rotating disk 34 to drive the spline shaft 33 to rotate under the drive of the torque application module 36 to apply torque to the smart door lock handle.

[0041] Please see Figures 2-3 The torque application module 36 includes a torque sensor 361 and a servo motor 362. The transfer platform 32 is equipped with a transmission module connected to the rotating disk 34. The servo motor 362 is mounted on the mounting bracket 31. One end of the torque sensor 361 is connected to the output shaft of the servo motor 362 through a first coupling 363, and the other end of the torque sensor 361 is connected to the transmission module through a second coupling 364.

[0042] For example, the transmission module is a gear transmission module, which includes a meshing drive gear and a driven gear ring. The drive gear is drivenly connected to the second coupling 364, and the driven gear ring is fixedly connected to the rotating disk 34. During the test, the torque application module 36 drives the driven gear ring and the rotating disk 34 to rotate by controlling the rotation of the drive gear. In other embodiments, the transmission module can also be a sprocket transmission module, a belt transmission module, etc., as long as it can drive the rotation of the rotating disk 34.

[0043] In this embodiment, the torque application module 36 applies torque to the smart door lock handle as follows: The servo motor 362 is started, and the servo motor 362 rotates and drives the drive gear in the transfer platform 32 to rotate in sequence through the first coupling 363, the torque sensor 361, and the second coupling 364. The rotation of the drive gear drives the driven gear ring and the rotating disk 34 to rotate in sequence. The key fit between the rotating disk 34 and the spline shaft 33 drives the spline shaft 33 and the connecting fixture 37 to apply torque to the smart door lock handle. At the same time, the torque sensor 361 monitors the applied torque value in real time.

[0044] Please continue reading. Figures 2-4 The static tension application module 35 includes a guide wheel 351, a steel wire rope 352, and a counterweight 353. The guide wheel 351 is rotatably mounted on the mounting frame 31. One end of the steel wire rope 352 is connected to the counterweight 353, and the other end of the steel wire rope 352 passes around the guide wheel 351 and is connected to the spline shaft 33 through the rotary connector module 38. In this embodiment, the counterweight 353 is a combined counterweight, which can be selected and adapted according to the weight required for the actual test.

[0045] The rotary connector module 38 includes a connector body 381, a retaining ring 382, ​​and a connecting post 383. The connector body 381 is slidably mounted on the mounting bracket 31 and connected to the wire rope 352. The connecting post 383 is mounted on the spline shaft 33. The connector body 381, retaining ring 382, ​​and connecting post 383 are sequentially connected together. The connecting post 383 is stepped, and the retaining ring 382 is fitted onto the connecting post 383 and rotatably engages with it. In this embodiment, the interlocking design between the connecting post 383 and the retaining ring 382 allows the connecting post 383 to rotate within the retaining groove of the retaining ring 382. Therefore, when the spline shaft 33 drives the connecting post 383 to rotate, the retaining ring 382 is unaffected by the rotation.

[0046] Optionally, the static tension application module 35 further includes a movable pusher 354, which is mainly used to cooperate with the push-pull module 39 to release the applied static tension. Please refer again. Figures 3-4 The connector body 381 is slidably mounted on the movable pusher 354. A stop boss 384 is provided on the side of the movable pusher 354 near the transfer platform 32. When the movable pusher 354 moves towards the transfer platform 32 under the drive of the push-pull module 39, it abuts against the stop boss 384, thereby pulling the connector body 381 to release the static tension exerted by the counterweight 353 on the spline shaft 33 through the connector body 381. For example, the push-pull module 39 is a cylinder.

[0047] The rotary connector module 38 also includes a connecting disk 385 and a tension sensor 386, such as Figure 4As shown, the connecting plate 385 and the tension sensor 386 are sequentially arranged between the buckle 382 and the stop boss 384. The tension sensor 386 is used to detect the applied static tension value.

[0048] In this embodiment, the static tension application module 35 applies torque to the smart door lock handle as follows: The weight of the counterweight 353 is the applied static tension. The counterweight 353 is transmitted to the connector body 381 via the steel wire rope 352. The connector body 381 transmits the static tension to the spline shaft 33 sequentially via the tension sensor 386, the connecting plate 385, the buckle 382, ​​and the connecting post 383. The spline shaft 33 then applies static tension to the smart door lock handle via the connecting fixture 37. Simultaneously, the tension sensor 386 monitors the magnitude of the applied static tension in real time. Next, when the static tension needs to be released after the test, the push-pull module 39 drives the movable push bracket 354 to slide, causing the movable push bracket 354 to abut against the stop boss 384 to apply a pushing force until the applied pushing force is equal to the static tension generated by the counterweight 353. At this point, the static tension applied to the spline shaft 33 is released.

[0049] like Figures 5-7 As shown, the positioning component 20 includes a horizontal slide rail 21 and a test push plate 22. The test push plate 22 is slidably mounted on the horizontal slide rail 21 and its position can be locked by the locking component 23. The fixing fixture 10 is detachably mounted on the test push plate 22. Specifically, there are two horizontal slide rails 21, and a slide table 24 is provided on the horizontal slide rail 21. The test push plate 22 is mounted on the slide table 24. To facilitate the sliding of the slide table 24, a handle 25 is provided on the slide table 24. The operator pulls the slide table 24 on the horizontal slide rail 21 by holding the handle 25.

[0050] The locking assembly 23 of the embodiment includes a base 231, a locking shaft 232, and a positioning block 233. The locking shaft 232 is movably mounted on the base 231, and the positioning block 233 is mounted on the side wall of the slide 24. The positioning block 233 is provided with a positioning groove 234, which is, for example, a V-shaped groove. When the locking shaft 232 extends out, it extends into the positioning groove 234 to lock and position the positioning block 233 and the slide 24.

[0051] For example, the locking shaft 232 is driven and controlled by the handle 235. A positioning roller 236 is provided at the front end of the locking shaft 232. The positioning roller 236 abuts against the groove wall of the positioning groove 234 to form a locking and limiting fit. Correspondingly, the base 231 is provided with a position sensor 237 for detecting whether the locking shaft 232 is in the working position. The position sensor 237 is, for example, a photoelectric sensor.

[0052] Furthermore, the positioning component 20 in this embodiment also includes a plurality of pre-calibration brackets 26 arranged at intervals. An installation cylinder 27 is installed inside each pre-calibration bracket 26, and a calibration ball 28 is installed inside the installation cylinder 27 via a spring. A ball groove 238 that mates with the calibration ball 28 is provided on one side of the positioning block 233. Specifically, as... Figure 6 The calibration ball 28 in the middle of the pre-calibration bracket 26 at the position shown abuts against the ball groove 238 on the positioning block 233. This position is the test station. Correspondingly, the pre-calibration brackets 26 on both sides are used to determine whether the fixing fixture 10 is in the waiting test station or the test completion station.

[0053] This invention also provides a method for testing the static tensile force and torsion resistance of a smart door lock handle, applicable to the aforementioned smart door lock handle static tensile force and torsion resistance testing device, comprising the following steps:

[0054] S1) The operator installs the smart door lock into the fixing fixture 10;

[0055] S2) The positioning component 20 positions the fixed fixture 10 at the test station, and the locking component 23 locks the fixed fixture 10 at the test station.

[0056] S3) Pass the smart door lock handle through the connecting groove 371 of the connecting fixture 37, and make the smart door lock handle and the connecting groove 371 make contact and fit.

[0057] S4) Start the test. The static tension application module 35 applies static tension to the smart door lock handle through the spline shaft 33 and the connecting fixture 37 for 30 seconds. After the static tension test is completed, the application of static tension is released.

[0058] S5) The torque application module 36 is activated, and the spline shaft 33 and the connecting fixture 37 are rotated by the rotating disk 34 to apply torque to the smart door lock handle for 30 seconds. After the torque test is completed, the torque application is released.

[0059] Although the present invention has been described above by way of embodiments, the above embodiments are only used to exemplify possible implementations of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent substitutions or changes made by those skilled in the art in accordance with the present invention should also be covered by the scope of protection defined by the claims of the present invention.
