[0053] See also Figures 1 to 10 The present invention provides a door lock 200, which includes a first panel 130, a handle 25, a square shaft 28 and a first lock body 46, or includes a first panel 130, a handle 25, a square shaft 28 and a second lock body 49. The first panel 130 is provided with a accommodating chamber 10, and the accommodating chamber 10 is provided with a fixing portion 13 for installing a first motor 40. The first panel 130 is provided with a through hole 22 connected to the accommodating chamber 10, and the through hole 22 is used for allowing the connecting member 37 of the first lock core 31 to pass through so that the connecting member 37 is connected to the first motor 40. The handle 25 is rotatably mounted on the first panel 130. The square shaft 28 is connected to the handle 25 and can rotate as the handle 25 rotates. The first lock body 46 includes a first lock tongue 52, wherein the first motor 40 is used to drive the first lock core 31 to move through the connecting member 37 to drive the first lock tongue 52 to extend and retract. The second lock body 49 includes a second lock tongue 55 and a second motor 43 . The second motor 43 is used to connect to the second lock core 34 and drive the second lock core 34 to move so as to drive the second lock tongue 55 to extend and retract.

[0054] In the above-mentioned door lock 200, the first panel 130 is provided with a fixing portion 13 for mounting the first motor 40 and a through hole 22 for the connecting member 37 to pass through, so that the door lock 200 can be compatible with the model in which the first panel 130 has the first motor 40 and the model in which the lock body has the second motor 43.

[0055] Specifically, please combine Figure 1 、 Figure 3 and Figure 5 In models where the first panel 130 includes the first motor 40, a housing 10 is defined within the first panel 130. A fixing portion 13 for mounting the first motor 40 is defined within the housing 10. The first motor 40 is mounted on the fixing portion 13 within the housing 10. The connector 37 of the first lock core 31 passes through the through hole 22 and connects to the first motor 40. When the first motor 40 receives a control signal and begins operating, the first motor 40 drives the first lock core 31 to move via the connector 37, thereby causing the first lock tongue 52 to extend and retract.

[0056] Please combine Figure 2 、 Figure 4 and Figure 6 In the model with a second motor 43 in the lock body, the second motor 43 is disposed in the second lock body 49 and is connected to the second lock core 34. When the second motor 43 receives a control signal and starts working, it drives the second lock core 34 to move, thereby driving the second lock tongue 55 to extend and retract.

[0057] In the related art, for fully automatic smart door locks, there are generally two motor placement methods: one is rear-mounted on the panel, and the other is built into the lock body. Both motor placement methods have corresponding advantages and disadvantages.

[0058] The rear-panel motor arrangement, with the motor located on the rear panel, is larger and provides greater driving force, adapting to a wider range of lock types and more complex lock body structures, such as lock locks with a top and bottom hook, further enhancing door lock security. However, due to the long transmission mechanism connecting the motor to the lock tongue, unlocking speed is relatively slow, and the larger motor and transmission mechanism may generate more noise during operation, especially when transmitting torque between metal parts.

[0059] With a motor positioned directly inside the lock body, the motor is located a short distance from the lock tongue, enabling quick response and unlocking. Furthermore, since the motor is closer to the door and typically uses a smaller motor, the compact structure produces relatively low noise levels during operation. However, the motor's small size limits its driving force, making it difficult to operate a wider range of locks and more complex lock body structures, such as a lock with a top and bottom hook, potentially compromising the overall security of the door lock.

[0060] Therefore, when users purchase fully automatic smart door locks, after selecting the style they like, they may choose to return or exchange the entire product because their requirements for unlocking speed, unlocking sound, and driving the top and bottom hooks are not met.

[0061] In the embodiment of the present invention, the user unlocking operation remains unchanged, the first panel 130 and the second panel 150 of the door lock 200 do not need to be replaced, and the opening size remains unchanged. By replacing the first lock cylinder 31 and the second lock cylinder 34, the first motor 40 and the second motor 43, and the first lock body 46 and the second lock body 49 and other accessories, the two layouts of the motor inside the lock body and the motor behind the panel can be changed. Specifically, the first panel 130 is provided with a fixing portion 13 for mounting the first motor 40 and a through hole 22 for the connector 37 to pass through, making the door lock 200 compatible with models with the first panel 130 having the first motor 40 and models with the lock body having the second motor 43.

[0062] In one embodiment, when the model in which the first panel 130 is provided with a first motor 40 is changed to a model in which the lock body is provided with a second motor 43, the first panel 130 and the second panel 150 of the door lock 200 do not need to be replaced, the opening size remains unchanged, the first lock core 31 with the connecting piece 37 can be replaced with the second lock core 34, the first motor 40 is removed, and the first lock body 46 is replaced with the second lock body 49 with the second motor 43 built in.

[0063] In one embodiment, for a model in which the lock body has a second motor 43 and is changed to a model in which the first panel 130 has a first motor 40, the first panel 130 and the second panel 150 of the door lock 200 do not need to be replaced, the opening size remains unchanged, the second lock core 34 can be replaced with a first lock core 31 with a connecting piece 37, the first motor 40 is installed in the accommodating space 10 in the first panel 130, the first motor 40 is connected to the first lock core 31 through the connecting piece 37, and the second lock body 49 with the built-in second motor 43 is replaced with the first lock body 46.

[0064] After purchasing a door lock product according to the present invention, users can contact the product manufacturer or a third-party service provider to schedule a professional installation service. The installer will assess the installation conditions on-site and provide installation or replacement services as needed. Users with sufficient technical knowledge and hands-on skills may also consider replacing the internal door lock components themselves, such as changing the door lock type. Users may choose to retain the replaced door lock components for future use, such as backup or repair. If the replaced door lock components meet the return requirements, users may also consider returning them to the manufacturer.

[0065] Please combine Figures 1 to 6 The handle 25 is located on the side of the first panel 130 facing the interior of the room and is a component that the user can grasp and operate. The user can easily unlock or lock the door by turning the handle 28. The handle 25 is provided with a square groove, and one end of the square shaft 28 is embedded in the square groove. The size and shape of the square groove match the size and shape of the end of the square shaft 28 embedded in the square groove, ensuring that the square shaft 28 is firmly embedded in the square groove, allowing the square shaft 28 to rotate with the rotation of the handle 25. The other end of the square shaft 28 is connected to the first lock body 46 or the second lock body 49. When the user turns the handle 25, the square shaft 28 transmits this movement to the lock tongue within the lock body, thereby unlocking and locking the door.

[0066] Optionally, combine Figure 5 and Figure 7 First lock body 46 also includes a beveled bolt 106. When locked, beveled bolt 106 extends in conjunction with first lock bolt 52, forming an oblique angle with the door frame to securely engage with the door frame's locking slot. Beveled bolt 106 is typically used as a secondary locking point for the door, working in conjunction with first lock bolt 52 to further enhance the security of door lock 200.

[0067] Please combine Figure 6 and Figure 8 Second lock body 49 also includes a scissor tongue 108. When locked, scissor tongue 108 extends in conjunction with second lock tongue 55. Scissor tongue 108 consists of two intersecting lock tongues, capable of simultaneously locking with two different lock slots in the door frame. Scissor tongue 108 is typically used as a secondary locking point for the door, working in conjunction with second lock tongue 55 to further enhance the security of door lock 200.

[0068] Figure 11 This is a diagram showing the dimensions of the mounting holes for door lock 200 on door panel 110. The diagram indicates the relative positions and specific dimensions of the mounting holes for door lock 200 on door panel 110 to ensure proper installation. When the door lock 200 is upgraded, the dimensions of the mounting holes remain unchanged, preserving the structural integrity and aesthetics of door panel 110. It also allows for quick replacement of door lock 200 parts, simplifying installation.

[0069] In certain embodiments, the power of the first motor 40 is greater than the power of the second motor 43 .

[0070] In this way, the first motor 40 and the second motor 43 can flexibly adapt to different actual needs and improve the user experience to a certain extent.

[0071] Specifically, please combine Figure 1 、 Figure 3 and Figure 5 In models where the first panel 130 includes the first motor 40, a larger housing cavity 10 can be provided on the first panel 130 to accommodate the larger first motor 40, thereby being housed within the housing cavity 10 within the first panel 130. The first motor 40 drives the first lock cylinder 31 via the connector 37, which in turn drives the first lock tongue 52 to extend and retract, thereby opening and closing the door lock 200. The high power of the first motor 40 provides a strong driving force, making it suitable for other types of locks, including but not limited to top and bottom hooks, or more complex lock body structures, further enhancing the security of the door lock 200.

[0072] Please combine Figure 2 、 Figure 4 and Figure 6 In models where the lock body includes a second motor 43, the second motor 43 is relatively small and therefore accommodated within the second lock body 49. The second motor 43 is connected to the second lock cylinder 43, driving the second lock cylinder 43 to extend and retract the second lock tongue 55, thereby opening and closing the door lock 200. Because the second motor 43 is located directly within the second lock body 49 and a short distance from the second lock tongue 55, it enables rapid response and unlocking. Furthermore, the second motor 43's small size and proximity to the door panel 110 produce relatively little noise during operation.

[0073] In summary, the door lock 200 in the embodiment of the present invention is compatible with models in which the first panel 130 is equipped with a first motor 40 and models in which the lock body is equipped with a second motor 43. The first motor 40 or the second motor 43 can be flexibly selected according to actual needs, thereby improving the user experience to a certain extent.

[0074] In some embodiments, the fixing portion 13 is provided with a first mounting hole 16 , and the first motor 40 is provided with a second mounting hole 19 . The first motor 40 is mounted on the fixing portion 13 by fasteners passing through the first mounting hole 16 and the second mounting hole 19 .

[0075] In this way, the first motor 40 can be installed on the fixing portion 13 to work stably, thereby reducing wear and malfunction caused by movement or shaking.

[0076] Specifically, please combine Figure 5 and Figure 6 The fixing portion 13 includes a mounting post having a first mounting hole 16 formed therein, and the first motor 40 having a second mounting hole 19 formed therein. When installing the first motor 40, the mounting post is provided with the second mounting hole 19 so that the first motor 40 is positioned on the fixing portion 13, ensuring that the first mounting hole 16 and the second mounting hole 19 can be accurately aligned to avoid offset. The fasteners are provided through the first mounting hole 16 and the second mounting hole 19 to secure the first motor 40 to the fixing portion, thereby reducing wear and failure caused by movement or shaking of the first motor 40 during operation. Optionally, the fasteners include, but are not limited to, screws, pins, and the like.

[0077] The number of the first mounting holes 16 and the second mounting holes 19 can be specifically limited according to actual conditions, and the present invention does not make any specific restrictions on this. Figure 5 and Figure 6 The number of the first mounting holes 16 and the number of the second mounting holes 19 are both 3, and one first mounting hole 16 corresponds to one second mounting hole 19.

[0078] In some embodiments, the first motor 40 includes an output shaft 58 , the output shaft 58 is provided with a socket 61 , and one end of the connecting member 37 is embedded in the socket 61 so that the connecting member 37 rotates with the rotation of the output shaft 58 .

[0079] In this way, when the first motor 40 is working, it can drive the first lock core 31 to drive the first lock tongue 52 to extend and retract, thereby improving the convenience and efficiency of opening and closing the door lock 200 to a certain extent.

[0080] Specifically, please combine Figure 5One end of the connector 37 is embedded in the socket 61, and the size and shape of the socket 61 match the size and shape of the end of the connector 37 embedded in the socket 61, ensuring that the connector 37 can be firmly embedded in the socket 61. The other end of the connector 37 is connected to the body of the first lock core 31. When the first motor 40 receives the control signal and starts working, it generates rotational power and transmits it to the output shaft 58. Since one end of the connector 37 is already embedded in the socket 61 of the output shaft 58, the connector 58 will rotate as the output shaft 58 rotates. This rotation is transmitted to the body of the first lock core 31 through the connector 37, driving the first lock core 31 to drive the first lock tongue 52 to retract and retract, thereby realizing the opening and closing of the door lock 200, and improving the convenience and efficiency of opening and closing the door lock 200 to a certain extent.

[0081] Optionally, the connecting member 37 may be a square shaft, and the insertion hole 61 may be a square hole.

[0082] In certain embodiments, the first motor 40 includes a motor body 64 including a drive shaft and a reduction assembly connecting the drive shaft to the output shaft 58 .

[0083] In this way, through the cooperation of the motor body 64 and the deceleration assembly, it is ensured to a certain extent that the movement of driving the first lock core 31 to drive the first lock tongue 52 to extend and retract is smooth and accurate, thereby realizing the opening and closing of the door lock 200.

[0084] Specifically, please combine Figure 5 The first motor includes a motor body 64 and a reduction assembly 67. Optionally, the first motor 40 can be a DC motor. It is understood that in other embodiments, the first motor 64 can also be a stepper motor, a servo motor, etc.

[0085] When the first motor 40 receives the control signal and is powered on, the stator coil in the first motor 40 generates a magnetic field, converting electrical energy into mechanical energy through electromagnetic induction, causing the drive shaft to start rotating, and the rotational power of the drive shaft is transmitted to the reduction assembly connected to the drive shaft. The reduction assembly 67 reduces the speed of the drive shaft through its internal mechanical structure (such as gear reduction, worm gear reduction, etc.) and increases the torque output accordingly. The decelerated power is transmitted to the output shaft 58 connected to the reduction assembly 67 through the reduction assembly 67, driving the first lock core 31 connected to the output shaft 58 through the connector 37 to move, so that the first lock core 31 drives the first lock tongue 52 to extend and retract, ensuring that the entire process is smooth and accurate to a certain extent, and realizing the opening and closing of the door lock 200.

[0086] The appropriate motor and reduction assembly can be selected according to the specific requirements of the door lock 200 (such as unlocking speed, noise level, power consumption, etc.), and the present invention does not make specific limitations on this.

[0087] In some embodiments, the first lock body 46 includes a reverse locking tongue 70 , and a reverse locking operating member 73 is provided on the first panel 130 . The reverse locking operating member 73 is configured to cause the reverse locking tongue 70 to extend and retract when operated.

[0088] In this way, an additional locking function can be provided to further enhance the safety of the door lock 200 .

[0089] Specifically, the anti-lock tongue 70 is used to provide an additional locking function. When the anti-lock tongue 70 is extended, it will cooperate with the corresponding door frame lock slot to prevent the door from opening even if the door lock has been opened. Figures 1 to 6 The first panel 130 is provided with a reverse locking member 73 for convenient operation by the user from indoors. The reverse locking member 73 is connected to the reverse locking tongue 70 via a mechanical member including but not limited to a connecting rod, a gear or a transmission shaft, so that when the reverse locking member 73 is operated, the reverse locking tongue 70 can be extended or retracted.

[0090] When the anti-lock function is to be activated, the user operates the anti-lock operating member 73, causing the anti-lock operating member 73 to extend the anti-lock tongue 70, causing the anti-lock tongue 70 to lock into the lock slot of the door frame. When the anti-lock function is to be deactivated, the user operates the anti-lock operating member 73, causing the anti-lock operating member 73 to retract the anti-lock tongue 70, allowing the door to be opened normally. The anti-lock function improves the security of the door lock 200 to a certain extent, allowing the door lock 200 to be closed when necessary to prevent unauthorized entry.
