Description

Technical Field

[0001] The present application relates to the technical field of lock body detection, and in particular to a multifunctional lock body quality and life detection device. Background Art

[0002] When using a smart lock, you enter a password or fingerprint to provide an unlock signal. The motor inside the smart lock drives the main lock tongue switch to rotate, unlocking the main lock tongue. Then, the handle of the smart lock is rotated forward a certain angle, driving the inclined lock tongue to retract into the lock body. Pulling the handle completes the door opening action. However, the lifespan of the lock tongue of a smart lock usually requires tens of thousands or even hundreds of thousands of tests. If this is done manually, the inspection efficiency is low and the labor cost is high.

[0003] The smart lock is also equipped with an induction lock tongue, an induction element and an induction motor. The induction lock tongue is pushed into the lock body. The induction element receives the induction signal, controls the rotation of the induction motor, and unlocks the oblique lock tongue, allowing the oblique lock tongue to move telescopically.

[0004] In the related art, a driving device is used to drive the main lock tongue switch to rotate, causing the main lock tongue to extend and retract to detect the service life of the smart lock. However, simply driving the main lock tongue switch to rotate cannot accurately detect the main lock tongue, and the length of the main lock tongue extending out of the lock body cannot be accurately measured, which reduces the accuracy of the detection. Utility Model Content

[0005] In view of this, the present application provides a multifunctional lock body quality and life detection device to solve or improve the problem of being unable to accurately measure the extended length of the main lock tongue.

[0010] The controller is communicatively connected with the driving mechanism and the first distance sensor respectively.

[0011] Beneficial effect: The driving mechanism drives the main lock tongue switch to rotate, thereby driving the main lock tongue to extend out of the lock body. The first distance sensor detects the length of the main lock tongue extending out of the lock body and transmits the data information to the controller. The controller determines whether the length standard of the main lock tongue extension is met. It can accurately detect whether the main lock tongue is stuck and then determine the service life of the lock body. Compared with the prior art, which can only determine whether the main lock tongue extends out of the lock body but cannot determine whether the length of the extension reaches the standard, the solution of this application has higher accuracy in lock body life detection.

The first connecting section is provided with a connecting hole, and the mounting plate is provided with a threaded hole corresponding to the connecting hole. The adjusting bolt passes through the connecting hole and is screwed to the threaded hole, and the first cylinder and the second cylinder are both connected to the second connecting section.

[0017] In an optional embodiment, the connecting hole is a waist-shaped hole, and the connecting hole is arranged along the extension and contraction direction of the oblique lock tongue to adjust the distance between the cylinder positioning plate and the lock body.

[0018] In an optional embodiment, a positioning member is further included, which is used to connect with the lock body. A positioning hole is opened on the positioning member, and a mounting hole is opened on the mounting plate corresponding to the positioning hole. The positioning bolt passes through the positioning hole and the mounting hole in sequence and is connected to the positioning nut.

[0019] In an optional embodiment, the mounting hole is an oblong hole, which is arranged along the extension and contraction direction of the vertical oblique lock tongue, and the position of the lock body is adjusted so that the first cylinder and the second cylinder correspond to the oblique lock tongue and the induction lock tongue respectively.

[0020] In an optional embodiment, a locking member is further included, which is mounted on the mounting plate and is used to lock the lock body and the mounting plate.

[0021] In an optional embodiment, two second distance sensors are further included. The second distance sensors are installed on the mounting plate corresponding to the top and bottom hooks of the lock body to detect the length of the top and bottom hooks of the lock body extending out of the lock body. The two second distance sensors are respectively connected to the controller for communication.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0033] The smart lock is also provided with an induction lock tongue 20, an induction element and an induction motor. A limit slot is provided on the oblique lock tongue 18, and a limit plate is connected to the output shaft of the induction motor. When the induction lock tongue 20 extends out of the lock body 2, the limit plate is inserted into the limit slot to limit the telescopic movement of the oblique lock tongue 18. The induction lock tongue 20 is pushed into the lock body 2, and the induction element receives the induction signal to control the rotation of the induction motor. The limit plate is away from the limit slot, so that the oblique lock tongue 18 can be telescopically moved.

[0034] The following combination Figures 1 to 5 , describing the embodiments of the present application.

[0035] According to an embodiment of the present application, a multifunctional lock body quality and life detection device is provided, comprising: a mounting plate 1, a drive mechanism, a first distance sensor 4, and a controller 5;

[0036] Specifically, the mounting plate 1 is used to install the lock body 2; the driving mechanism is installed on the mounting plate 1, and the driving end of the driving mechanism is used to drive the main lock tongue switch 3 of the lock body 2 to rotate; the first distance sensor 4 is installed on the mounting plate 1 and is used to be arranged corresponding to the main lock tongue 19 of the lock body 2 to detect the length of the main lock tongue 19 extending out of the lock body 2; the controller 5 is respectively communicated with the driving mechanism and the first distance sensor 4.

[0037] The driving mechanism drives the main lock tongue switch 3 to rotate, thereby driving the main lock tongue 19 to extend out of the lock body 2. The first distance sensor 4 detects the length of the main lock tongue 19 extending out of the lock body 2, and transmits the data information to the controller 5. The controller 5 determines whether the length standard of the main lock tongue 19 is reached. It can accurately detect whether the main lock tongue 19 is stuck, and then determine the service life of the lock body 2. Compared with the prior art, which can only determine whether the main lock tongue 19 extends out of the lock body 2 but cannot determine whether the length of the extension from the lock body 2 meets the standard, the solution of this application has higher accuracy in detecting the life of the lock body 2.

[0038] The multifunctional lock body quality and life detection device provided in the present application can detect the oblique lock tongue 18, the main lock tongue 19 and the induction lock tongue 20, and detect the quality and service life of the lock body 2.

[0039] In a specific embodiment, Figure 3As shown, the adjusting plate 21 is further provided with an elongated hole 22, which is arranged along the extension and retraction direction of the main lock tongue 19. The mounting plate 1 is provided with a threaded hole corresponding to the elongated hole 22, through which a screw 26 is threadedly connected, thereby securing the adjusting plate 21 to the mounting plate 1. The first distance sensor 4 is mounted on the adjusting plate 21. By adjusting the corresponding positions of the threaded hole and the elongated hole 22, the distance between the first distance sensor 4 and the main lock tongue 19 is adjusted, thereby enabling detection of the main lock tongue 19 on different lock bodies 2.

[0040] It should be noted that the number of main lock tongues 19 provided on different lock bodies 2 is different, and the number of first distance sensors 4 can be multiple, and they correspond one-to-one to the multiple main lock tongues 19 .

[0041] In a more preferred embodiment, an alarm is installed on the mounting plate 1, and the alarm is communicated with the controller 5. When the first distance sensor 4 detects that the extended length of the main lock tongue 19 does not meet the requirement, the signal is transmitted to the controller 5. The controller 5 controls the alarm to sound an alarm to remind the staff that the main lock tongue 19 is damaged at this time.

[0042] In one embodiment, Figure 1 and Figure 2 As shown, it also includes:

[0043] The first cylinder 6 is mounted on the mounting plate 1, and the piston rod of the first cylinder 6 is used to be arranged corresponding to the oblique lock tongue 18 of the lock body 2;

[0044] The second cylinder 7 is mounted on the mounting plate 1, and the piston rod of the second cylinder 7 is used to be arranged corresponding to the induction lock tongue 20 of the lock body 2;

[0045] The first cylinder 6 and the second cylinder 7 are respectively connected to the controller 5 for communication.

[0046] The second cylinder 7 pushes the induction lock tongue 20 and pushes it into the lock body 2. The induction element receives the induction signal and controls the rotation of the induction motor. The limit plate moves away from the limit slot, so that the oblique lock tongue 18 can be telescopically moved. The first cylinder 6 pushes the oblique lock tongue 18 to move and can push the oblique lock tongue 18 into the lock body 2, which proves that the oblique lock tongue 18, the induction lock tongue 20 and the induction motor are working normally. The first cylinder 6 and the second cylinder 7 work together to detect the oblique lock tongue 18, the induction lock tongue 20 and the induction motor.

[0047] In one embodiment, Figure 2 As shown, it also includes a cylinder positioning plate 8, which is provided with a first connecting section and a second connecting section. The first connecting section is provided with a connecting hole 9, and the mounting plate 1 is provided with a threaded fixing hole corresponding to the connecting hole 9. The adjusting bolt 10 passes through the connecting hole 9 and is screwed to the threaded fixing hole. The first cylinder 6 and the second cylinder 7 are both connected to the second connecting section.

[0048] In one embodiment, Figure 2 As shown, the connecting hole 9 is a waist-shaped hole and is arranged along the extension and contraction direction of the oblique lock tongue 18 to adjust the distance between the cylinder positioning plate 8 and the lock body 2. The adjusting bolt 10 passes through the connecting hole 9 and is connected to the threaded fixing hole. Before locking the first connecting section to the mounting plate 1, the adjusting bolt 10 adjusts the distance between the connecting hole 9 and the threaded fixing hole, thereby adjusting the distance between the first gas rod and the second cylinder 7 and the oblique lock tongue 18 and the induction lock tongue 20 respectively, so that different lock bodies 2 can be used.

[0049] It needs to be further explained that, Figure 2 As shown, the positioning plate is an L-shaped plate, the first connecting section is the horizontal plate of the L-shaped plate, and the second connecting section is the longitudinal plate of the L-shaped plate. Two through-holes are provided on the longitudinal plate, and the cylinder barrels of the first cylinder 6 and the second cylinder 7 are fixedly connected to the two through-holes respectively.

[0050] In one embodiment, Figure 4 As shown, it also includes a positioning member 11, which is used to connect with the lock body 2. A positioning hole is opened on the positioning member 11, and a mounting hole 12 is opened on the mounting plate 1 corresponding to the positioning hole. The positioning bolt 13 passes through the positioning hole and the mounting hole 12 in sequence and is connected with the positioning nut.

[0051] It should be explained that the positioning member 11 is a positioning plate.

[0052] In one embodiment, Figure 4 As shown, the mounting hole 12 is an oblong hole and is arranged along the extension and contraction direction of the oblique lock tongue 18. The position of the lock body 2 is adjusted so that the first cylinder 6 and the second cylinder 7 correspond to the oblique lock tongue 18 and the sensing lock tongue 20, respectively. The positioning bolt 13 passes through the positioning hole and the mounting hole 12 and is connected to the positioning nut. Before the positioning bolt 13 and the positioning nut lock the positioning member 11 to the mounting plate 1, the position of the positioning member 11 is adjusted along the extension and contraction direction of the oblique lock tongue 18, so that the first cylinder 6 and the second cylinder 7 are aligned with the oblique lock tongue 18 and the sensing lock tongue 20, respectively.

[0053] In one embodiment, Figure 1 As shown, a locking member 14 is also included. The locking member 14 is installed on the mounting plate 1 and is used to lock the lock body 2 and the mounting plate 1 .

[0054] It is further explained that the locking member 14 includes a U-shaped plate, a locking wrench and a U-shaped rod. The top plate of the U-shaped plate is fixed on the mounting plate 1. The two ends of the U-shaped rod are rotatably connected to the two side plates of the U-shaped plate. The locking wrench is rotatably connected to the two side plates of the U-shaped plate. A connecting column 25 is fixedly connected to the lock body 2. The U-shaped rod is sleeved on the connecting column 25. When the locking wrench is pulled, the locking wrench abuts against the U-shaped rod, so that the U-shaped rod is pressed against the lock body 2.

[0055] As further explained, the locking member 14 may be implemented as an adjustable clamp 304 .

[0056] In one embodiment, Figure 1 As shown, two second distance sensors 15 are also included. The second distance sensors 15 are mounted on the mounting plate 1 corresponding to the top and bottom hooks 16 of the lock body 2 to detect the length of the top and bottom hooks 16 extending from the lock body 2. The two second distance sensors 15 are respectively in communication with the controller 5. The main lock tongue switch 3 can simultaneously drive the top and bottom hooks 16 to extend and retract. The two second distance sensors 15 respectively detect the length of the top and bottom hooks 16 extending from the lock body 2. When the extended length is different from the set length, the alarm sounds.

[0057] Specifically, the first distance sensor 4 and the second distance sensor 15 can be ultrasonic ranging sensors, laser ranging sensors, infrared ranging sensors and radar sensors.

[0058] In one embodiment, Figure 1 As shown, a counterweight 17 is also included, which is connected to the top and bottom hooks 16 of the lock body 2 to simulate a real unlocking environment.

[0059] It is further explained that the top and bottom hooks 16 are lock tongues installed on the top, bottom and edge of the door to enhance the anti-theft performance and increase the difficulty of prying the door.

[0060] In one embodiment, the driving mechanism is a first motor, which is mounted on the mounting plate 1 and is connected to the main deadbolt switch 3 through a transmission assembly. The first motor is in communication with the controller 5 .

[0061] The first motor drives the main lock tongue 19 to rotate, thereby controlling the extension and retraction of the main lock tongue 19 and detecting the main lock tongue 19; the second motor drives the handle to rotate, thereby controlling the extension and retraction of the oblique lock tongue 18 and detecting the oblique lock tongue 18. The controller 5 drives the main lock tongue switch 3 and the handle to rotate respectively through the first motor and the second motor, thereby improving the degree of automation.

[0062] Further explanation is that, Figure 5 As shown, a wheel disc 23 is mounted on the output shaft of the first motor, and a connecting column 25 is fixed to the edge of the wheel disc 23. The connecting column 25 is connected to the rotation of the connecting rod 24. The other end of the connecting rod 24 is connected to the main lock tongue switch 3 for rotation. When the wheel disc 23 rotates, the main lock tongue switch 3 is driven to rotate back and forth through the connecting rod 24.

[0063] It is further explained that a second motor is also included, and a pulley is installed on the output shaft of the second motor. The pulley is connected to the rotating shaft of the handle through a belt, and the second motor drives the rotating shaft of the handle to rotate back and forth.

[0064] Below is an embodiment, combined with Figures 1 to 5A comprehensive explanation of all the above plans is given.

[0065] Install the lock body 2 on the mounting plate 1, and connect the positioning bolt 13 with the positioning nut through the positioning hole and the mounting hole 12. Before the positioning bolt 13 and the positioning nut lock the positioning piece 11 on the mounting plate 1, adjust the position of the positioning piece 11 along the extension and contraction direction of the vertical oblique lock tongue 18 so that the first cylinder 6 and the second cylinder 7 are aligned with the oblique lock tongue 18 and the induction lock tongue 20 respectively; then pull the locking wrench, and the locking wrench abuts against the U-shaped rod so that the U-shaped rod is pressed against the lock body 2; the adjusting bolt 10 passes through the connecting hole 9 and is connected to the threaded fixing hole. Before locking the first connecting section with the mounting plate 1, adjust the connecting hole 9 and the adjusting bolt 10 so that the connecting hole 9 and the induction lock tongue 20 are aligned. The distance between the threaded fixing holes is adjusted, and then the distance between the first gas rod and the second cylinder 7 and the oblique lock tongue 18 and the induction lock tongue 20 are adjusted respectively; the counterweight block is connected to the top and bottom hooks 16 to simulate the real unlocking environment; the first motor is turned on, and the first motor drives the wheel 23 to rotate, and the wheel 23 drives the connecting rod 24 to reciprocate, and the main lock tongue switch 3 is driven to rotate back and forth through the connecting rod 24, driving the main lock tongue 19 to move telescopically, and the first distance sensor 4 detects whether the extended length of the main lock tongue 19 meets the preset value. When it does not meet the preset value, it means that the main lock tongue 19 may be damaged inside, and the alarm sounds, prompting the staff to check.

[0066] The second motor is turned on, and the second motor drives the pulley to rotate. The pulley is connected to the rotating shaft of the handle through a belt, driving the rotating shaft of the handle to rotate back and forth, and driving the oblique lock tongue 18 to move telescopically.

[0067] Turn off the second motor, and the second cylinder 7 pushes the sensing lock tongue 20 and pushes it into the lock body 2. The sensing element receives the sensing signal, controls the induction motor to rotate, and the limit plate moves away from the limit slot, so that the oblique lock tongue 18 can be telescopically moved. The first cylinder 6 pushes the oblique lock tongue 18 to move and can push the oblique lock tongue 18 into the lock body 2, which proves that the oblique lock tongue 18, the sensing lock tongue 20 and the induction motor are working normally. The first cylinder 6 and the second cylinder 7 work together to detect the oblique lock tongue 18, the sensing lock tongue 20 and the induction motor.

[0068] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the accompanying application.
