Description

Technical Field

[0001] This application relates to the field of smart door locks, and in particular to smart lock bodies. Background Technology

[0002] Smart locks are improved versions of traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. Smart locks are the locking mechanisms in access control systems.

[0003] The lock body is a crucial component of smart locks. Existing smart lock bodies are derived from traditional mechanical lock bodies. Smart lock bodies typically use a stepped transmission method to extend the latch and outer bolt. In a mechanical lock body, a first and second limiting groove are provided. When the lock cylinder rotates and aligns with the first limiting groove, the latch extends out of the lock body. When the lock cylinder rotates and aligns with the second limiting groove, both the latch and outer bolt extend out simultaneously. However, in existing smart locks, the lock cylinder is driven by a motor. After the motor drives the lock cylinder to rotate, it may become stuck in the first limiting groove, unable to move further to the second limiting groove. This can result in the lock body failing to lock completely, and may even cause the motor to burn out during the continuous rotation towards the second limiting groove. Summary of the Invention

[0052] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in 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, and 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.

[0053] Existing technologies often suffer from lock bodies that can jam, resulting in the inability to lock completely.

[0054] Therefore, this application provides a smart lock body, wherein the smart lock body includes,

[0055] Lock case;

[0056] A lock cylinder assembly, comprising a lock cylinder body and a first driving member, wherein the first driving member is disposed within the lock cylinder body, and the lock cylinder body drives the first driving member to rotate a fixed angle by an electric means;

[0057] A locking tongue assembly, the locking tongue assembly including a slanted tongue member movable in a first direction and an outer locking tongue member;

[0059] The transmission assembly includes a first transmission member, an intermediate transmission member, and a second transmission member. The first transmission member is connected to the first driving member, the second transmission member is connected to the inclined tongue member, and the intermediate transmission member is connected to the outer locking tongue member. The intermediate transmission member is disposed between the first transmission member and the second transmission member, and the intermediate transmission member forms a gear transmission connection with the first transmission member and the second transmission member. The inclined tongue member and the outer locking tongue member can extend out of the side strip plate along the first direction in the driving member of the lock cylinder body.

[0060] Example 1:

[0061] In existing technology, smart locks refer to locks that are improved upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. Smart locks are the locking actuators in access control systems.

[0062] The lock body is a crucial component of smart locks. Existing smart lock bodies are derived from traditional mechanical lock bodies. Smart lock bodies typically use a stepped transmission method to extend the latch and outer bolt. In a mechanical lock body, a first and second limiting groove are provided. When the lock cylinder rotates and aligns with the first limiting groove, the latch extends out of the lock body. When the lock cylinder rotates and aligns with the second limiting groove, both the latch and outer bolt extend out simultaneously. However, in existing smart locks, the lock cylinder is driven by a motor. After the motor drives the lock cylinder to rotate, it may become stuck in the first limiting groove, unable to move further to the second limiting groove. This can result in the lock body failing to lock completely, and may even cause the motor to burn out during the continuous rotation towards the second limiting groove.

[0063] Please refer to the attached document. Figure 1 To be continued Figure 6 As shown, the first direction X of this application refers to the height direction of the smart lock body 10, that is, the direction from top to bottom or from bottom to top of the smart lock body 10. The transmission component 500 is positioned higher than the side strip 400, and the side strip 400 is positioned lower than the transmission component 500. The second direction Y of this application refers to the length direction of the smart lock body 10. The inclined bolt 310 is positioned to the left of the inner locking bolt 340, and the inner locking bolt 340 is positioned to the right of the inclined bolt 310. The third direction Z of this application refers to the width direction of the smart lock body 10, that is, the direction from front to back or from back to front of the smart lock body 10. The second housing 120 is positioned forward of the first housing 110, and the first housing 110 is positioned backward of the second housing 120.

[0064] Appendix Figure 1 This is a structural schematic diagram of the smart lock body 10 of this application. Please refer to the attached diagram. Figure 1 As shown, the smart lock body 10 of this application includes a lock shell 100. All other components of the smart lock body 10 except the lock shell 100 are disposed inside the lock shell 100 to protect the smart lock body 10.

[0065] In one embodiment, the lock housing 100 includes a first housing 110 and a second housing 120 disposed along a third direction Z. The first housing 110 is connected to the second housing 120 by a fastener 130. The fastener 130 is disposed along a third direction Z and passes through the transmission assembly 500 to restrict other components of the smart lock body 10, excluding the lock housing 100, within the receiving cavity of the lock housing 100.

[0066] Please refer to the attached document. Figure 1As shown, the smart lock body 10 of this application also includes a lock cylinder assembly 200. The lock cylinder assembly 200 of this application achieves a fixed-angle rotation by electric means, thereby realizing precise control of the extension of the bolt in the smart lock body 10. Therefore, it is not necessary to further set corresponding limiting grooves in the smart lock body to achieve corresponding limiting. Furthermore, the lock cylinder assembly 200 of this application can also be rotated manually.

[0067] Please refer to the attached document. Figure 1 As shown, the smart lock body 10 of this application also includes a latch assembly 300. The latch assembly 300 includes a slanted latch 310 and an outer latch 320 that can move along the first direction X. When the slanted latch 310 and the outer latch 320 move outward along the first direction X, they can lock. When the slanted latch 310 and the outer latch move inward along the first direction X, they can unlock. Under the drive of the transmission assembly 500 of this application, the slanted latch 310 can be locked or the slanted latch 310 and the outer latch 320 can be locked simultaneously.

[0068] In one embodiment, the outer locking tongue 320 includes a first outer locking tongue 321 and a second outer locking tongue 322 spaced apart along the second direction Y. Furthermore, the first outer locking tongue 321 is provided with second outer locking tongues 322 spaced apart on both sides along the second direction Y. The multiple arrangements of the outer locking tongue 320 can further enhance the locking capability.

[0069] In one embodiment, the latch assembly 300 of this application further includes an inner latch 340, which is disposed along a first direction X and is used to achieve internal locking of the smart lock body 10. The inner latch 340 is driven from one end in the direction X, and the outer latch 320 is driven from the other end in the direction X. That is, the difference between the inner latch and the outer latch 320 of this application lies in the different directions of locking and unlocking. The inner latch 340 achieves locking and unlocking from the inside, while the outer latch 320 achieves locking and unlocking from the outside.

[0070] Please refer to the attached document. Figure 1 As shown, the smart lock body 10 of this application also includes a side strip plate 400. The side strip plate 400 is used to connect with the door body. The side strip plate 400 is arranged along the second direction Y, and the lock cylinder assembly 200 and the transmission assembly 500 are both arranged on one side of the side strip plate 400 along the second direction Y. The lock shell 100 of this application has an opening on one side along the first direction X. The side strip plate 400 is arranged at the opening of the lock shell 100 to restrict the lock cylinder assembly 200 and the transmission assembly 500 within the lock shell 100, allowing only a portion of the bolt assembly 300 to extend out of the side strip plate 400. Furthermore, most of the structure of the bolt assembly 300 is still arranged on one side of the side strip plate 400 along the second direction Y, and only a portion of the structure can extend out of the side strip plate 400 to achieve locking.

[0071] Please refer to the attached document. Figure 1 As shown, the smart lock body 10 of this application also includes a transmission assembly 500. The transmission assembly 500 transmits power via gears, thereby reducing transmission torque and making the transmission smoother, and preventing the motor from locking due to the limiting groove during transmission. The transmission assembly 500 of this application is used to transmit power from the lock cylinder assembly 200 to the bolt assembly 300 to achieve locking and unlocking of the smart lock body 10 of this application.

[0072] Appendix Figure 2 This is a schematic diagram of the structure of the smart lock body 10 after removing the lock shell 100. (Attached) Figure 3 This is a schematic diagram of an alternative structure of the smart lock body 10 after removing the lock shell 100. (Attached) Figure 2 and appendix Figure 3 Only for the appendix Figure 1 Further explanation of the middle part of the structure is attached. Figure 2 and appendix Figure 3 Middle and Appendix Figure 1 The same parts will not be repeated. Please refer to the appendix. Figure 2 and appendix Figure 3 As shown, the transmission assembly 500 of this application includes a first transmission member 510, an intermediate transmission member 520 and a second transmission member 530. The first transmission member 510 is connected to the first driving member 220 in the lock cylinder assembly 200. The second transmission member 530 is connected to the inclined tongue member 310. The intermediate transmission member 520 is connected to the outer locking tongue member 320. The intermediate transmission member 520 is disposed between the first transmission member 510 and the second transmission member 530. The intermediate transmission member 520 forms a gear transmission connection with the first transmission member 510 and the second transmission member 530. Under the drive of the lock cylinder body 210, the inclined tongue member 310 and the outer locking tongue can extend the side strip plate 400 along the first direction X.

[0073] The latch assembly 300 also includes a first connecting plate 330, which is arranged along the second direction Y. The outer latch 320 includes a first outer latch 321 and a second outer latch 322 arranged at intervals along the second direction Y. The second outer latch 322 is provided in two sets, respectively arranged on both sides of the first outer latch 321 along the second direction Y. The first outer latch 321 is directly connected to the intermediate transmission member 520. The first connecting plate 330 is connected to the second outer latch 322 and the intermediate transmission member 520 respectively. Under the drive of the lock cylinder assembly 200, the first outer latch 321 and the second outer latch 322 extend out of the side strip plate 400 synchronously along the first direction X. Of course, the first outer latch 321 and the second outer latch 322 can also be retracted and unlocked at the same time. Therefore, the first outer locking tongue 321 of this application directly locks and unlocks through the intermediate transmission member 520, while the second outer locking tongue 322 is locked and unlocked by the first connecting plate 330 transmitting kinetic energy to the second outer locking tongue 322.

The first driving member 220 is disposed inside the lock cylinder body 210. The lock cylinder body 210 is connected to a drive motor, thereby facilitating the lock cylinder body 210 to drive the first driving member 220 to rotate by electric drive.

[0076] In one embodiment, the main body of the first driving member 220 is located inside the lock cylinder body 210, and under the movement of the first driving member 220, part of the first driving member 220 can extend out of the lock cylinder body 210, thereby forming contact with the first transmission member 510 in different directions and realizing the rotation of the first transmission member 510 in different directions.

The second drive rod 312 is arranged along the first direction X, and the locking inclined tongue 311 is provided at the bottom of the second drive rod 312 along the first direction X. When the second drive rod 312 moves along the first direction X, it can control the locking inclined tongue 311 to extend or retract from the side strip plate 400. The limiting plate 313 is connected to the second drive rod 312, and the limiting plate 313 has a fourth limiting groove. The second transmission member 530 is partially located in the fourth limiting groove. The limiting plate 313 is spaced apart from the side strip plate 400 along the first direction X, thereby ensuring that the second drive rod 312 can drive the second transmission member 530 to move while moving. The first elastic element 314 is located between the limiting plate 313 and the side strip plate 400 to drive the second drive rod 312 to move upward and ensure that the second transmission element 530 always abuts against the first drive rod 525, so that the first drive rod 525 can realize the synchronous movement of the oblique tongue 310 when it moves.

[0084] Appendix Figure 5 This is a structural schematic diagram of the second limiting member 527 of this application. Please refer to the attached diagram. Figure 5 As shown, the second intermediate member 524 of this application is disposed along the first direction X. The second intermediate member 524 is disposed on one side of the first intermediate structure 523-1 along the third direction Z. The second intermediate member 524 is provided with a third limiting groove 524-1 along the first direction X. The first central shaft 521 extends along the first direction X into the third limiting groove 524-1 to limit the movement path of the second intermediate member 524. The intermediate transmission member 520 also includes a second limiting member 527.

That is, the two ends of the second limiting groove 527-1 along the first direction X have the third limiting surface 527-11 and the fourth limiting surface 527-12. The second limiting groove 527-1 also includes a second idle position 527-13 located between the third limiting surface 527-11 and the fourth limiting surface 527-12. That is, when the second limiting rod 527-2 is not in contact with the third limiting surface 527-11 or the fourth limiting surface 527-12, it is in the second idle position 527-13. The second limiting rod 527-2 is connected to the first intermediate structure 523-1. The second limiting rod 527-2 extends along the third direction Z into the second limiting groove 527-1, so the second limiting rod 527-2 can rotate synchronously with the first intermediate structure 523-1. Furthermore, when the second limiting rod 527-2 abuts against the third limiting surface 527-11 and the fourth limiting surface 527-12 under the rotation of the first intermediate structure 523-1, the first intermediate structure 523-1 and the second intermediate member 524 rotate synchronously, thereby achieving synchronous movement of the inclined tongue member 310 and the outer locking tongue member 320. Further, when the second limiting rod 527-2 is located in the second idle position 527-13, the first intermediate structure 523-1 rotates independently, at which time the inclined tongue member 310 moves independently. The difference between the second limiting rod 527-2 contacting the third limiting surface 527-11 or the fourth limiting surface 527-12 in this application lies in the different directions of driving the second intermediate member 524 to move.

[0086] Appendix Figure 6 This is a structural schematic diagram of the first limiting member 526 of this application. Please refer to the attached diagram. Figure 6As shown, the intermediate transmission component 520 of this application further includes a first limiting component 526. The first limiting component 526 includes a first limiting groove 526-1 and a first limiting rod 526-2. The first limiting groove 526-1 is disposed on the first drive gear 522 and is disposed along the rotation trajectory of the first drive gear 522, that is, the first limiting groove 526-1 is an arc-shaped groove. The first limiting groove 526-1 includes a first limiting surface 526-11 and a second limiting surface 526-12 arranged at both ends of the rotation trajectory of the first drive gear 522. The first limiting groove 526-1 also includes a first idle position 526-13 located between the first limiting surface 526-11 and the second limiting surface 526-12, that is, when the first limiting rod 526-2 is not in contact with the first limiting surface 526-11 or the second limiting surface 526-12, it is in the first idle position 526-13. The first limiting rod 526-2 is connected to the first intermediate structure 523-1. The first limiting rod 526-2 extends along the third direction Z into the first limiting groove 526-1, so the first intermediate structure 523-1 can move synchronously with the first limiting rod 526-2. Furthermore, when the first driving gear 522 rotates, and the first limiting rod 526-2 abuts against the first limiting surface 526-11 and the second limiting surface 526-12, the first driving gear 522 and the first intermediate structure 523-1 rotate synchronously. At this time, the oblique tongue 310 is driven to move synchronously by the first driving gear 522 and the first intermediate structure 523-1. When the limiting rod is located in the first idle position 526-13, the first driving gear 522 rotates independently, and the oblique tongue 310 is driven to move independently by the first driving gear 522. The difference between the first limiting rod 526-2 contacting the first limiting surface 526-11 or contacting the second limiting surface 526-12 in this application lies in the different directions of driving the first intermediate structure 523-1 to move.

[0087] Furthermore, during this movement, the first limiting groove 526-1 located on the first drive gear 522 is the driving member, while the first limiting rod 526-2 located on the first intermediate structure 523-1 is the driven member.
