Description

Technical Field

[0001] This application relates to the field of lock body testing technology, specifically to a testing device. Background Technology

[0002] When using a smart lock, an unlock signal is sent by entering a password or fingerprint. The motor inside the smart lock drives the main bolt switch to rotate, unlocking the main bolt. Then, turning the smart lock handle drives the latch bolt to retract into the lock body, and pulling the handle completes the door opening action. When the user returns inside, turning the safety bolt switch extends the safety bolt out of the lock body and inserts it into the corresponding groove in the door frame, enhancing security.

[0003] Smart locks need to be tested before leaving the factory. The lifespan test of various lock tongues of smart locks usually requires tens of thousands or even hundreds of thousands of tests. If the test is carried out manually, the testing efficiency is low and the labor cost is high.

[0004] In related technologies, one device is used to test one type of lock tongue. After the test is completed, the lock body needs to be manually installed on another testing device to test other lock tongues. Each device can only test one type of lock tongue, and the lock body needs to be manually replaced in the middle, resulting in low testing efficiency. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] When using a smart lock, an unlock signal is sent by entering a password or fingerprint. The motor inside the smart lock drives the main bolt switch to rotate, unlocking the main bolt. Then, turning the smart lock handle drives the latch bolt to retract into the lock body, and pulling the handle completes the door opening action. When the user returns inside, turning the safety bolt switch extends the safety bolt out of the lock body and inserts it into the corresponding groove in the door frame, enhancing security.

[0038] Smart locks need to be tested before leaving the factory. The lifespan test of various lock tongues of smart locks usually requires tens of thousands or even hundreds of thousands of tests. If the test is carried out manually, the testing efficiency is low and the labor cost is high.

[0039] In related technologies, one device is used to test one type of lock tongue. After the test is completed, the lock body needs to be manually installed on another testing device to test other lock tongues. Each device can only test one type of lock tongue, and the lock body needs to be manually replaced in between, resulting in low testing efficiency. To solve or improve the problem of low lock body testing efficiency, this application provides a testing device.

[0040] The following is combined with Figures 1 to 8 This describes an embodiment of the present application.

[0041] According to an embodiment of this application, a testing device is provided for testing a lock body 20, which has a slanted bolt keyhole 12, a main bolt keyhole 13, a safety bolt keyhole 14, and a trigger bolt 15.

[0042] The testing device includes: mounting plate 1, first testing mechanism 2, second testing mechanism 3, third testing mechanism 4, testing cylinder 5, and controller.

[0043] Specifically, such as Figure 1 and Figure 8 As shown, the mounting plate 1 has a lock body positioning groove 101; the first testing mechanism 2 is mounted on the mounting plate 1, and the testing end of the first testing mechanism 2 is used to insert into the key hole 12 of the oblique lock tongue and drive the oblique lock tongue 21 of the lock body 20 to move telescopically; the second testing mechanism 3 is mounted on the mounting plate 1, and the testing end of the second testing mechanism 3 is used to insert into the key hole 13 of the main lock tongue and drive the main lock tongue 22 of the lock body 20 to move telescopically; the third testing mechanism 4 is mounted on the mounting plate 1, and the testing end of the third testing mechanism 4 is used to insert into the key hole 14 of the safety tongue and drive the safety tongue 23 of the lock body 20 to move telescopically; the testing cylinder 5 is mounted on the mounting plate 1, and the testing cylinder 5 is used to press the trigger tongue 15; the controller is electrically connected to the first testing mechanism 2, the second testing mechanism 3, the third testing mechanism 4 and the testing cylinder 5 respectively.

[0044] In this embodiment, such as Figure 1 and Figure 8 As shown, the lock body 20 needs to be tested before leaving the factory. The lock body 20 is snapped into the lock body positioning groove 101, so that the oblique lock tongue keyhole 12, the main lock tongue keyhole 13 and the safety tongue keyhole 14 provided on the lock body 20 are respectively inserted into the test end of the first test mechanism 2, the test end of the second test mechanism 3 and the test end of the third test mechanism 4. At the same time, the test cylinder 5 is arranged correspondingly to the trigger tongue 15. The controller controls the test end of the first test mechanism 2, the test end of the second test mechanism 3 and the test end of the third test mechanism 4 to drive the oblique lock tongue 21, the main lock tongue 22 and the safety tongue 23 to extend and retract, so as to test the oblique lock tongue 21, the main lock tongue 22 and the safety tongue 23. The test cylinder 5 reciprocates to press the trigger tongue 15 to test the trigger tongue 15.

[0045] The controller records the number of tests performed on the oblique locking bolt 21, main locking bolt 22, safety bolt 23, and trigger bolt 15. The controller controls the first testing mechanism 2, the second testing mechanism 3, the third testing mechanism 4, and the testing cylinder 5 to drive the locking bolt to move. After the preset number of tests is reached, the lock body 20 can operate normally and the test ends. The testing device provided in this application can simultaneously test the oblique locking bolt 21, main locking bolt 22, safety bolt 23, and trigger bolt 15, thereby improving the testing efficiency of the lock body 20.

[0046] Specifically, such as Figure 8 As shown, a connecting plate 24 is provided on the lock body 20, and the connecting plate 24 is snapped into the lock body positioning groove 101.

[0047] Specifically, the controller is a PLC controller.

[0048] In one embodiment, such as Figure 1 and Figure 8 As shown, it also includes a distance detection mechanism 6, which is mounted on the mounting plate 1. The distance detection mechanism 6 is used to detect the distance that the safety tongue 23 extends out of the lock body 20. The distance detection mechanism 6 is electrically connected to the controller.

[0049] In this embodiment, the controller controls the distance detection mechanism 6 to measure the distance that the safety tongue 23 extends out of the lock body 20, and transmits the measurement result to the controller. The controller records the measurement result and analyzes the measurement result. When the measurement result is different from the preset distance, it is determined that the safety tongue 23 has failed the test.

[0050] Specifically, the distance detection mechanism 6 can be either a distance sensor or a proximity switch, with the proximity switch model being SN04-N.

[0051] In one embodiment, such as Figure 3 and Figure 4 As shown, the first testing mechanism 2 includes: a first motor 201 and a slanted locking tongue key 202. The first motor 201 is mounted on the mounting plate 1 and is equipped with a first torque monitoring module. The slanted locking tongue key 202 is mounted on the output shaft of the first motor 201. The slanted locking tongue key 202 is used to insert into the slanted locking tongue keyhole 12 and drive the slanted locking tongue 21 of the lock body 20 to extend and retract. The first motor 201 and the first torque monitoring module are electrically connected to the controller.

[0052] In this embodiment, the output shaft of the first motor 201 is connected to the angled locking key 202. The angled locking key 202 is inserted into the angled locking key hole 12. The first motor 201 drives the angled locking key 202 to rotate, thereby driving the angled locking tongue 21 to extend and retract, and testing the angled locking tongue 21. At the same time, the first torque monitoring module can measure the torque required by the angled locking key 202 during the extension and retraction of the angled locking tongue 21.

[0053] It should be noted that the first torque monitoring module transmits the first torque value of the oblique locking tongue key 202 during the process of driving the oblique locking tongue 21 to extend and retract to the controller. The controller compares the first torque value with the first preset torque value. If the first torque value is less than or equal to the first preset torque value, the oblique locking tongue 21 is determined to have passed the test. If the first torque value is greater than the first preset torque value, the oblique locking tongue 21 is determined to have failed the test.

[0054] Specifically, the first motor 201 uses a servo motor. The brand and model of the servo motor is Huichuan MS1H4-40B30CB-T331R. The servo motor is electrically connected to the servo driver, and the servo driver is electrically connected to the controller to transmit torque values ​​to the controller. The model of the servo driver is SV630NS2R8I.

[0055] Specifically, the first preset torque value is 3 N·m.

[0056] In one embodiment, such as Figure 3 and Figure 4 As shown, the angled locking tongue key 202 includes a first connecting post 2021 and a drive shaft 2022. One end of the first connecting post 2021 has a first connecting groove along its axial direction, and the other end is coaxially connected to the drive shaft 2022. The first connecting groove is inserted into the output shaft of the first motor 201. The side wall of the output shaft of the first motor 201 has a first keyway 2011, and the inner wall of the first connecting groove has a second keyway. The first keyway 2011 and the second keyway are connected by a first connecting key. The drive shaft 2022 is used to insert into the angled locking tongue keyhole 12.

[0057] In this embodiment, the first connecting slot is inserted into the output shaft of the first motor 201, and the relative movement of the first connecting post 2021 and the output shaft of the first motor 201 in their rotation direction is restricted by the first connecting key. The structure is simpler and easier to install.

[0058] Specifically, such as Figure 4 As shown, the drive shaft 2022 is a square shaft. In practical applications, when the lock body 20 is installed on the door panel, the square shaft is connected to the handle. Turning the handle drives the oblique locking tongue 21 to extend or retract through the transmission structure inside the lock body 20, thereby opening or locking the door.

[0059] In one embodiment, such as Figure 3 and Figure 5As shown, the second testing mechanism 3 includes a second motor 301 and a main lock tongue key 302. The second motor 301 is mounted on the mounting plate 1 and is equipped with a second torque monitoring module. The main lock tongue key 302 is mounted on the output shaft of the second motor 301. The main lock tongue key 302 is used to insert into the main lock tongue keyhole 13 and drive the main lock tongue 22 of the lock body 20 to extend and retract. The second motor 301 and the second torque monitoring module are electrically connected to the controller.

[0060] In this embodiment, such as Figure 3 and Figure 5 As shown, the output shaft of the second motor 301 is connected to the main lock tongue key 302. The main lock tongue key 302 is inserted into the main lock tongue keyhole 13. The output shaft of the second motor 301 drives the main lock tongue key 302 to rotate, driving the main lock tongue 22 to extend and retract, and testing the main lock tongue 22. At the same time, the second torque monitoring module can measure the torque required by the main lock tongue key 302 during the extension and retraction of the main lock tongue 22.

[0061] It should be noted that, as Figure 3 and Figure 5 As shown, the second torque monitoring module transmits the second torque value of the main locking tongue key 302 during the process of driving the main locking tongue 22 to extend and retract to the controller. The controller compares the second torque value with the second preset torque value. If the second torque value is less than or equal to the second preset torque value, the test of the main locking tongue 22 is determined to be passed. If the second torque value is greater than the second preset torque value, the test of the main locking tongue 22 is determined to be failed.

[0062] Specifically, the second motor 301 is a servo motor. The brand and model of the servo motor is Huichuan MS1H4-40B30CB-T331R. The servo motor is electrically connected to the servo driver, and the servo driver is electrically connected to the controller to transmit torque values ​​to the controller. The model of the servo driver is SV630NS2R8I.

[0063] Specifically, the second preset torque value is 1.5 N·m.

[0064] In one embodiment, such as Figure 3 and Figure 5 As shown, the main lock tongue key 302 includes a second connecting post 3021 and a lever 3022. One end of the second connecting post 3021 has a second connecting groove along its axial direction. The second connecting groove is inserted into the output shaft of the second motor 301. The side wall of the output shaft of the second motor 301 has a third keyway 3011. The inner wall of the second connecting groove has a fourth keyway. The third keyway 3011 and the fourth keyway are connected by a second connecting key. The lever 3022 is connected to the side wall of the second connecting post 3021. The lever 3022 and the second connecting post 3021 are used to insert into the main lock tongue keyhole 13.

[0065] In this embodiment, the second connecting slot is inserted into the output shaft of the second motor 301, and the relative movement of the second connecting post 3021 and the output shaft of the second motor 301 in their rotation direction is restricted by the second connecting key. The structure is simpler and easier to install.

[0066] It should be noted that, as Figure 3 , Figure 5 and Figure 8 As shown, in daily life, when a key is inserted into the lock cylinder and turned, it drives the lever on the lock cylinder to rotate, which in turn drives the main bolt 22 to extend and retract through the transmission structure inside the lock body 20. The second connecting shaft is equivalent to the key, and the lever 3022 is equivalent to the lever. The second motor 301 drives the second connecting shaft to rotate, which in turn drives the lever 3022 to rotate, and the rotation of the lever 3022 drives the main bolt 22 to extend and retract.

[0067] In one embodiment, such as Figure 3 and Figure 6 As shown, the third testing mechanism 4 includes a third motor 401 and a safety tongue key 402. The third motor 401 is mounted on the mounting plate 1 and is equipped with a third torque monitoring module. The safety tongue key 402 is mounted on the output shaft of the third motor 401. The safety tongue key 402 is used to insert into the safety tongue keyhole 14 and drive the safety tongue 23 of the lock body 20 to move telescopically. The third motor 401 and the third torque monitoring module are electrically connected to the controller.

[0068] In this embodiment, such as Figure 3 and Figure 6 As shown, the output shaft of the third motor 401 is connected to the safety tongue key 402. The safety tongue key 402 is inserted into the safety tongue key hole 14. The output shaft of the third motor 401 drives the safety tongue key 402 to rotate, driving the safety tongue 23 to extend and retract, and testing the safety tongue 23. At the same time, the third torque monitoring module can measure the torque required by the safety tongue key 402 during the extension and retraction of the safety tongue 23.

[0069] It should be noted that the third torque monitoring module transmits the third torque value of the safety tongue key 402 during the process of driving the safety tongue 23 to the controller. The controller compares the third torque value with the third preset torque value. If the third torque value is less than or equal to the third preset torque value, the test of the safety tongue 23 is determined to be passed. If the third torque value is greater than the third preset torque value, the test of the safety tongue 23 is determined to be failed.

[0070] Specifically, the third motor 401 is a servo motor. The brand and model of the servo motor is Huichuan MS1H1-10B30CB-T330Z. The servo motor is electrically connected to the servo driver, and the servo driver is electrically connected to the controller to transmit torque values ​​to the controller. The model of the servo driver is SV630NS1R6I.

[0071] Specifically, the third preset torque value is 1.5 N·m.

[0072] In one embodiment, such as Figure 3 and Figure 6 As shown, the safety latch key 402 includes a third connecting post 4021 and an insert plate 4022. One end of the third connecting post 4021 has a third connecting groove along its axial direction. The third connecting groove is inserted into the output shaft of the third motor 401. The side wall of the output shaft of the third motor 401 has a fifth keyway 4011. The inner wall of the third connecting groove has a sixth keyway. The fifth keyway 4011 and the sixth keyway are connected by a third connecting key. The insert plate 4022 is connected to the end of the third connecting post 4021 and is used to insert into the safety latch key hole 14.

[0073] It should be noted that, as Figure 3 , Figure 6 and Figure 8 As shown, in daily life, the safety latch 23 knob is inserted into the safety latch keyhole 14. Rotating the safety latch 23 knob drives the safety latch 23 to extend and retract through the transmission structure inside the lock body 20. The insert plate 4022 is equivalent to the safety latch 23 knob. The third motor 401 drives the insert plate 4022 to rotate, thereby driving the safety latch 23 to extend and retract.

[0074] In this embodiment, such as Figure 1 and Figure 7 As shown, it also includes a test box 19. One side plate of the test box 19 is set as a mounting plate 1. The first test mechanism 2, the second test mechanism 3, the third test mechanism 4 and the controller are located inside the test box 19. The mounting plate 1 is provided with three through holes 7. The test ends of the first test mechanism 2, the second test mechanism 3 and the third test mechanism 4 pass through the three through holes 7 respectively.

[0075] In this embodiment, such as Figure 1 and Figure 7As shown, the first testing mechanism 2, the second testing mechanism 3, the third testing mechanism 4, and the controller are located inside the testing box 19, resulting in a more compact structure. The drive shaft 2022, the paddle 3022, and the insert plate 4022 pass through the three through holes 7. When the lock body 20 is positioned on the lock body positioning groove 101, the drive shaft 2022, the paddle 3022, and the insert plate 4022 are respectively inserted into the oblique lock tongue keyhole 12, the main lock tongue keyhole 13, and the safety tongue keyhole 14. Furthermore, the testing cylinder 5 corresponds to the trigger tongue 15. Additionally, the distance detection mechanism 6 corresponds to the safety tongue 23.

[0076] In one embodiment, such as Figure 1 As shown, it also includes a touch screen 8, which is electrically connected to the controller;

[0077] And / or, it also includes multiple indicator lights 9, each of which is electrically connected to the controller.

[0078] Specifically, the multiple indicator lights 9 include alarm indicator light 901, qualified indicator light 902, and unqualified indicator light 903.

[0079] The following is an example, combined with Figures 1 to 8 A comprehensive explanation of all the above-mentioned plans is provided.

[0080] The operator installs the lock body 20 onto the lock body positioning groove 101. The drive shaft 2022, the paddle 3022, and the insert plate 4022 are respectively inserted into the oblique bolt keyhole 12, the main bolt keyhole 13, and the safety bolt keyhole 14. The test cylinder 5 corresponds to the trigger bolt 15, and the distance detection mechanism 6 corresponds to the safety bolt 23. Each extension or retraction of the oblique bolt 21, the main bolt 22, the safety bolt 23, and the trigger bolt 15 triggers the corresponding sensing module. Each sensing module is connected to the controller via a transmission line.

[0081] The operator uses the touchscreen 8 to set the number of tests for the angled latch 21 and a first preset torque value. The test count is 3 times. The controller controls the first motor 201 to drive the angled latch key 202 to rotate, which in turn drives the angled latch 21 to extend and retract through the transmission structure inside the lock body 20, thus testing the angled latch 21. Each time the angled latch 21 extends or retracts, the corresponding sensing module sends a test signal to the controller until the set number of tests for the angled latch 21 is reached. The controller combines the first torque value from each test by the first torque monitoring module to determine whether the test for the angled latch 21 has passed. If it passes, the pass indicator 902 illuminates and the trigger tongue 15 is tested. If it fails, the fail indicator 903 and the alarm indicator 901 illuminate, and the test stops.

[0082] The operator sets the number of tests for the trigger tongue 15 to 3 via the touchscreen 8. The controller then controls the test cylinder 5 to drive the trigger tongue 15 to extend and retract, testing it. Each extension and retraction of the trigger tongue 15 sends a test signal to the controller via the corresponding sensing module, continuing until the set number of tests is reached. If the controller receives the test signals from the sensing module at regular intervals, it indicates that the trigger tongue 15 did not jam during the test, and the trigger tongue 15 is considered to have passed the test. The pass indicator 902 illuminates, and the main lock tongue 22 is then tested. If the controller receives test signals from the sensing module at inconsistent intervals or if the intervals are interrupted, it indicates that the trigger tongue 15 jammed during the test, and the trigger tongue 15 is considered to have failed the test. The fail indicator 903 and the alarm indicator 901 illuminate, and the test is stopped.

[0083] The operator uses the touchscreen 8 to set the number of tests for the main bolt 22 and a second preset torque value in the controller. The test count is 20 times. The controller controls the second motor 301 to drive the main bolt key 302 to rotate, which in turn drives the main bolt 22 to extend and retract through the transmission structure inside the lock body 20, thus testing the main bolt 22. Each time the main bolt 22 extends or retracts, the corresponding sensing module sends a test signal to the controller until the set number of tests for the main bolt 22 is reached. The controller combines the second torque value from each test by the second torque monitoring module to determine whether the main bolt 22 has passed the test. If it passes, the pass indicator 902 illuminates and the safety bolt 23 is tested. If it fails, the fail indicator 903 and the alarm indicator 901 illuminate, and the test stops.

[0084] The operator uses the touchscreen 8 to set the number of tests for the safety latch 23, the third preset torque value, and the preset distance for the safety latch 23 to extend out of the lock body 20. The number of tests is set to 3, and the preset distance is 15mm to 25mm. The controller controls the third motor 401 to drive the safety latch key 402 to rotate, which in turn drives the safety latch 23 to extend and retract through the transmission structure inside the lock body 20, thus testing the safety latch 23. Each time the safety latch 23 extends or retracts, the corresponding sensing module sends a test signal to the controller until the set number of tests for the safety latch 23 is reached. The controller combines the third torque value measured by the third torque monitoring module each time with the distance the safety latch 23 extends out of the lock body 20 measured by the detection mechanism 6 to determine whether the test for the safety latch 23 has passed. If the set number of tests for the safety tongue 23 is reached, and the third torque value measured each time is less than or equal to the third preset torque value, and the distance the safety tongue 23 extends out of the lock body 20 each time meets the preset distance for the safety tongue 23 extending out of the lock body 20, then it is determined whether the test of the safety tongue 23 has passed, and the qualified indicator light 902 will light up. If any of the above conditions are met, then it is determined that the test has failed, and the unqualified indicator light 903 and the alarm indicator light 901 will light up, and the test will stop.

[0085] After the lock body 20 test is completed, the staff will remove the lock body 20 and install the lock body 20 that was not tested on the lock body positioning groove 101.

[0086] A boom 18 is connected to the side wall of the test chamber 19, and a touch screen 8 is connected to the boom 18.

[0087] The test box 19 is equipped with a pass indicator light 902, a fail indicator light 903, an alarm indicator light 901, a start button 16, a stop button 17, a power indicator light 10, and an emergency stop button 11, all of which are electrically connected to the controller. The controller adopts the EtherCAT bus technology of the PLC, which improves the testing efficiency of the servo motor and the accuracy of interactive data. Automatic testing of a single lock body 20 takes 20 seconds, which is 66% more efficient than manual testing.

[0088] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
