Technical Field

[0001] The utility model relates to the field of smart locks, and in particular to a handle mechanism for smart locks and a smart lock. Background Art

[0002] As people's security awareness gradually increases, convenient and easy-to-use smart locks are gradually entering people's lives, and smart locks are gradually being used in residential areas and factories to replace traditional door locks. Existing smart locks are generally equipped with fingerprint recognition systems or password lock systems. Users do not need to carry traditional keys, and can lock and unlock the door without keys.

[0003] If you encounter a technical failure or special situation, you can use a special unlocking method to unlock the door, such as violent unlocking or technical unlocking. This will increase security risks to some extent. Therefore, in order to further improve the security of smart locks, it is necessary to continue to update and iterate the product in the direction of anti-violent opening and / or anti-technical opening.

[0004] Violent unlocking refers to the process of forcibly pressing down on the handle through a sleeve to open the door lock; technical unlocking refers to the process of holding the door handle with force so that the handle and the square rod are separated from their original axial position, and then quickly pressing down on the handle to open the door lock.

[0005] From the above, it can be seen that the smart locks in the prior art have the problem of low security. Utility Model Content

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0034] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0035] In order to solve the problem of low security of smart locks in the prior art, the utility model provides a handle mechanism for a smart lock and a smart lock. Among them, the following smart lock includes the following handle mechanism for a smart lock.

[0036] like Figures 1 to 5As shown, the handle mechanism for the smart lock includes a clutch assembly 10, a handle body 20, a transmission rod 30 and a locking assembly 40. The clutch assembly 10 includes a flexibly connected clutch seat 11 and a clutch rotating block 12. One end of the clutch seat 11 away from the clutch rotating block 12 is connected to the handle body 20. The transmission rod 30 is connected to one end of the clutch rotating block 12 away from the clutch seat 11, and the transmission rod 30, the clutch seat 11 and the clutch rotating block 12 are coaxially arranged. The locking assembly 40 is movably arranged on the clutch seat 11 to lock or disengage with the clutch rotating block 12.

[0037] By flexibly connecting the clutch seat 11 and the clutch rotating block 12 in the clutch assembly 10, the rigid connection structure originally integrally connected from the handle body 20 to the transmission rod 30 is replaced by the clutch assembly 10, so that the handle mechanism of the utility model has the function of preventing technical opening, thereby improving the safety of the smart lock.

[0038] In the process of using the smart lock of the utility model, if the user uses a legal identity recognition method to open the smart lock, the locking assembly 40 moves to lock the clutch rotating block 12 and the clutch seat 11 together, so that the action of the handle body 20 can be transmitted to the transmission rod 30 through the clutch assembly 10 to achieve unlocking. If the user uses an illegal method, such as a technical unlocking method (that is, wanting to unlock without verifying the legal identity), the locking assembly 40 will not lock the clutch rotating block 12 and the clutch seat 11 together. At this time, the flexible connection between the clutch seat 11 and the clutch rotating block 12 will make it impossible for the force applied to the handle body 20 to be transmitted to the transmission rod 30 through the clutch seat 11 and the clutch rotating block 12 in turn, that is, the smart lock cannot be opened.

[0039] Therefore, the present application provides a clutch assembly 10 and flexibly connects the clutch seat 11 and the clutch rotating block 12, thereby effectively reducing the risk of technical unlocking, thereby solving the problem of low security of smart locks in the prior art.

[0040] like Figure 1 to Figure 2 as well as Figures 5 and 6 As shown, the clutch assembly 10 also includes a flexible connector 13, and the clutch seat 11 is flexibly connected to the clutch rotating block 12 through the flexible connector 13. By setting the flexible connector 13, a flexible connection between two rigid connection structures can be achieved, which is simple, easy to implement, and easy to install. Of course, it is also possible to change the structure or material of the clutch seat 11 and the clutch rotating block 12 themselves so that the two can be directly connected and have a flexible connection effect at the connection point, rather than setting an additional flexible connector 13 separately. Therefore, as long as the connection strength between the two can be effectively reduced compared to the rigid connection, this handle mechanism has a certain effect of preventing technical unlocking.

[0041] Specifically, the flexible connector 13, the clutch seat 11 and the clutch rotating block 12 are coaxially arranged; at least one of the clutch seat 11 and the clutch rotating block 12 is provided with a receiving cavity adapted to the flexible connector 13, thereby ensuring that there is space for arranging the flexible connector 13. In addition, it is also necessary to ensure that the flexible connector 13 can be reliably connected to the clutch seat 11 and the clutch rotating block 12.

[0042] It should be noted that, in order to ensure the force transmission effect, it is necessary to ensure that the clutch seat 11 and the clutch rotating block 12 are coaxially arranged, but the flexible connector 13 does not need to ensure that it must be coaxial with the clutch seat 11 and the clutch rotating block 12. When there is one flexible connector 13, it is easier to achieve the coaxial arrangement of the flexible connector 13, the clutch seat 11 and the clutch rotating block 12. If there are multiple flexible connectors 13, multiple flexible connectors 13 are arranged at intervals and supported between the clutch seat 11 and the clutch rotating block 12. At this time, the multiple flexible connectors 13 cannot and do not need to be coaxially arranged with the clutch seat 11 and the clutch rotating block 12.

[0043] In one embodiment, the flexible connector 13 is fixedly connected to the clutch rotating block 12. This is conducive to the fixation of the flexible connector 13, ensuring that the flexible connection between the clutch seat 11 and the clutch rotating block 12 is not prone to failure.

[0044] In this embodiment, the flexible connecting member 13 includes a spring, and two ends of the spring are respectively in contact with the clutch seat 11 and the clutch rotating block 12 .

[0045] Specifically, after the smart lock is installed, the flexible connector 13 has a certain amount of compression in the extension direction of the transmission rod 30, so that the clutch rotating block 12 is applied with a thrust in the direction away from the clutch seat 11. At this time, if there is no locking assembly 40 to lock the clutch seat 11 and the clutch rotating block 12, the clutch seat 11 and the clutch rotating block 12 cannot be rigidly connected together, and the action of the locking assembly 40 needs to be authorized by a legitimate user to be opened, that is, only in the normal unlocking state, the locking assembly 40 will act to lock the clutch seat 11 and the clutch rotating block 12. If there is no authorization from a legitimate user, the clutch seat 11 and the clutch rotating block 12 will be affected by the flexible connector 13, thereby having a flexible connection effect.

[0046] like Figure 6 As shown, a locking groove 122 is provided on the clutch rotating block 12, and a movable locking assembly 40 is provided on the connecting disk 111 of the clutch seat 11, and the locking groove 122 and the locking assembly 40 at least partially overlap in the axial direction of the locking assembly 40 to ensure that the locking assembly 40 can extend into the locking groove 122, so as to lock the clutch seat 11 and the clutch rotating block 12 together through the locking assembly 40.

[0047] like Figure 1 to Figure 2As shown, the clutch assembly 10 also includes a clutch pressure cover 14, which is connected to the side of the clutch seat 11 close to the transmission rod 30 and forms a space therebetween for accommodating the clutch rotating block 12, and the clutch pressure cover 14 has a through hole 141 for avoiding the clutch rotating block 12 and the transmission rod 30.

[0048] Specifically, a threaded hole is provided on the connecting disk 111, and the clutch pressure cover 14 is connected to the clutch seat 11 by screws. A raised structure is provided on the cover body of the clutch pressure cover 14, and the edge of the clutch pressure cover 14 is connected to the clutch seat 11. The setting of the raised structure can prevent the clutch pressure cover 14 from directly pressing the clutch rotating block 12 on the clutch seat 11, causing the anti-technical opening failure.

[0049] Furthermore, a step structure is provided on the clutch rotating block 12 , and the through hole 141 of the clutch pressure cover 14 is adapted to the shaft section with a smaller diameter of the clutch rotating block 12 , and abuts against the step surface of the step structure to limit the clutch rotating block 12 .

[0050] In this embodiment, at least a portion of the clutch rotating block 12 can extend into the through hole 141 , that is, a shaft section of the clutch rotating block 12 with a smaller diameter is disposed in the through hole 141 .

[0051] exist Figure 1 In the specific embodiment shown, the outer circumference of the clutch rotating block 12 is composed of at least one arc segment and at least one plane segment. That is, the through hole 141 is a circular hole, while the outer circumference of the clutch rotating block 12 is not a cylindrical surface.

[0052] Specifically, in this embodiment, a portion of the clutch rotating block 12 extends out of the clutch pressure cover 14, and a connecting hole 123 ( Figure 6 The transmission rod 30 is provided with a connecting block 31 ( Figure 5 As shown in FIG. 1 , the transmission rod 30 partially extends into the clutch rotating block 12 and is connected to the connecting hole 123 through the connecting block 31, thereby locking the transmission rod 30 and the clutch rotating block 12.

[0053] Optionally, the connection block 31 is telescopically arranged on the transmission rod 30. During installation, the connection block 31 is pressed into the transmission rod 30, and after the end of the transmission rod 30 is inserted into a preset position in the clutch rotating block 12, the connection block 31 extends to the outer surface of the transmission rod 30 and enters the connection hole 123, connecting the transmission rod 30 and the clutch rotating block 12 into a whole.

[0054] exist Figure 1In the illustrated embodiment, the clutch swivel block 12 has a receiving groove for receiving the end of the transmission rod 30, and the receiving groove is adapted to the shape of the outer peripheral surface of the end of the transmission rod 30. In addition, the arc surface of the clutch swivel block 12 is adapted to the shape of the hole wall surface of the through hole 141, so that the axis of the clutch swivel block 12 and the through hole 141 coincide, preventing the clutch swivel block 12 from deviating from the axis and causing the transmission rod 30 to get stuck.

[0055] like Figures 1 to 4 As shown, the handle mechanism also includes a housing portion 50 and a limiter 60. The housing portion 50 has an accommodating space, in which at least a portion of the clutch assembly 10 and the locking assembly 40 are both located, at least a portion of the transmission rod 30 extends into the accommodating space, and the handle body 20 is located outside the housing portion 50. The limiter 60 is disposed on the clutch seat 11 and is offset from the rotation center of the clutch seat 11, and a limiter structure 51 cooperating with the limiter 60 is also disposed on the housing portion 50, so that after the handle body 20 and the clutch seat 11 rotate to a preset angle, the limiter 60 contacts the limiter structure 51, so that the limiter structure 51 stops the limiter 60. At the same time, by designing the material or structure of the clutch seat 11, and by increasing the cooperation between the limiter 60 and the limiter structure 51, the handle mechanism of the present application can have the function of preventing violent opening.

[0056] Specifically, a portion of the transmission rod 30 in the clutch assembly 10 is accommodated in the accommodation space, and the other end of the transmission rod 30 extends out of the housing portion 50. A portion of the clutch seat 11 also extends out of the housing portion 50 and is connected to the handle body 20. Therefore, when the operator applies force to the handle body 20 to drive the clutch seat 11 to rotate, the limiting member 60 disposed on the clutch seat 11 will also rotate with the clutch seat 11. At this time, the limiting member 60 will gradually approach the limiting structure 51 of the housing portion 50, and may contact the limiting structure 51 to achieve a limiting stop.

[0057] It should be noted that, during the normal unlocking process, when the user unlocks the door with legal authorization, the locking assembly 40 will lock the clutch seat 11 and the clutch rotating block 12. At this time, only a small rotation angle is required to transfer the rotation of one side of the handle body 20 to the transmission rod 30, thereby unlocking the lock body assembly. In this process, although the limiter 60 rotates with the clutch seat 11, the unlocking action has been achieved before the limiter 60 touches the limit structure 51. Therefore, the spacing angle between the limiter 60 and the limit structure 51 in the rotation direction needs to be specially considered. That is, the spacing angle between the limiter 60 and the limit structure 51 in the rotation direction should be greater than the rotation angle of the transmission rod 30 during normal unlocking, so as not to mistakenly start the limit function in advance.

[0058] In the case of anti-violent opening, that is, when the user cannot unlock the door through legal authorization, the locking assembly 40 will not lock the clutch seat 11 and the clutch rotating block 12. By rotating the handle body 20, the handle body 20 drives the clutch seat 11 to rotate, and the limit member 60 also rotates with the clutch seat 11 and gradually approaches the limit structure 51. At this time, since the clutch seat 11 and the clutch rotating block 12 are flexibly connected, the rotation amplitude of the clutch seat 11 cannot be completely transmitted to the clutch rotating block 12. At this time, the clutch seat 11 cannot drive the clutch rotating block 12 to rotate synchronously, so the limit member 60 will eventually touch the limit structure 51 and realize the limit stop of the two. Therefore, the force of the handle body 20 will mainly act on the clutch seat 11, and if the torsional force that the clutch seat 11 needs to bear is too large, it may cause damage to the clutch seat 11, thereby realizing the function of anti-violent opening.

[0059] That is to say, the limiting structure 51 can limit the rotation of the clutch seat 11. The clutch seat 11 can rotate freely within a preset range. When it exceeds the preset range, the limiting member 60 on the clutch seat 11 contacts the limiting structure 51 to stop, and the user can feel that the limiting member 60 is stopped through the handle body 20.

[0060] In this embodiment, the yield strength of the clutch seat 11 is less than the yield strength of the limiting structure 51 and the limiting member 60. Specifically, when the handle is opened by force, the limiting structure 51 and the limiting member 60 cooperate, and the handle body 20 continues to rotate, and the clutch seat 11 drives the limiting member 60 to continue to rotate. Since the yield strength of the limiting member 60 and the limiting structure 51 is greater than the yield strength of the clutch seat 11, when the handle body 20 continues to rotate, the clutch seat 11 breaks, so that the force on the handle body 20 cannot be transmitted to the clutch rotating block 12, and anti-violent opening is achieved.

[0061] like Figures 1 to 3 As shown, the housing 50 includes a lock housing 52 and a lock cover plate 53. The lock cover plate 53 is connected to the lock housing 52 to form an accommodation space therebetween, the handle body 20 is located on a side of the lock housing 52 away from the lock cover plate 53, the transmission rod 30 extends outward from the lock cover plate 53, the limiting structure 51 is disposed on the lock cover plate 53, and the limiting member 60 extends toward the lock cover plate 53. In addition, the handle body 20 is pivotally connected to the lock housing 52 via a bearing 70.

[0062] Specifically, the lock cover plate 53 is provided with a cover plate through hole for avoiding the transmission rod 30, and the diameter of the transmission rod 30 is smaller than the diameter of the cover plate through hole. The limiting structure 51 is arranged at a position deviated from the geometric center of the lock cover plate 53, and the cover plate through hole is located at the geometric center of the lock cover plate 53. That is, the limiting structure 51 is arranged eccentrically relative to the cover plate through hole.

[0063] like Figure 1As shown, there is one limiting structure 51. The limiting member 60 is detachably connected to the clutch seat 11.

[0064] In this embodiment, the angular difference between the limiting structure 51 and the limiting member 60 in the rotation direction of the clutch seat 11 is greater than 40 degrees. Of course, the angular difference between the two can be adjusted and set according to actual needs.

[0065] exist Figure 1 In the direction shown, the limiting structure 51 is arranged above the cover plate through hole on the lock cover plate 53, and the limiting member 60 is arranged at a direction greater than 90 degrees relative to the center line of the limiting structure 51. Through this arrangement, after the clutch seat 11 and the clutch rotating block 12 are locked by the locking assembly 40, the transmission rod 30 is driven to rotate to complete the unlocking process, and the limiting member 60 will not contact the limiting structure 51, thereby achieving a normal and legal unlocking process.

[0066] In this embodiment, the limiting structure 51 is a protrusion extending from the lock cover plate 53 toward the clutch seat 11, and the protrusion is arc-shaped, and the end of the arc-shaped protrusion is used to limit and stop with the limiting member 60. Such a protrusion can be formed on the lock cover plate 53 by stamping, which is simple and easy to implement and has good structural strength.

[0067] like Figure 3 As shown, the lock cover plate 53 is further provided with identification holes 531 , and two identification holes 531 are spaced apart and arranged on both sides of the limiting structure 51 .

[0068] Specifically, the overall structure of the limiting structure 51 is a crescent-shaped groove-like structure, and the bottom of the groove protrudes toward the direction close to the clutch seat 11 to form a protrusion. Openings are provided at both ends of the bottom of the limiting structure 51, which cooperate with the limiting member 60 through the opening surface, and a part of the limiting member 60 can cooperate with the edge of the opening.

[0069] Optionally, a portion of the limiting member 60 can extend into the end of the limiting structure 51 through the opening, and the limiting structure 51 is symmetrically arranged on the longitudinal center line of the lock cover plate 53 (eg, Figure 3 The lock cover plate 53 is provided with two identification holes 531, which are symmetrically arranged relative to the limiting structure 51. The identification holes 531 are respectively provided with identifications L and R, which are used to distinguish whether the smart lock opens the door in a left-hand opening mode or a right-hand opening mode.

[0070] like Figure 2 as well as Figures 4 to 5 As shown, the clutch seat 11 includes a connecting shaft 112 and a connecting disk 111 connected in sequence, the connecting shaft 112 is connected to the handle body 20, the connecting disk 111 is arranged toward the clutch rotating block 12, the limit member 60 is arranged on the connecting disk 111, and the connecting disk 111 is also provided with a guide groove 1111 for guiding the movement of the locking assembly 40.

[0071] Specifically, the locking assembly 40 is disposed on the connecting disk 111 and cooperates with the guide groove 1111. The limiting member 60 is threadedly connected to the connecting disk 111 or is integrally formed. In addition, the locking assembly 40 includes a locking member 41 and an elastic member 42.

[0072] The utility model also provides a smart lock, comprising the above-mentioned handle mechanism for the smart lock.

[0073] Specifically, the smart lock also includes a motor and a lock body assembly, the motor is used to drive the locking assembly 40, and the transmission rod 30 is connected to the lock body assembly.

[0074] The working process of this application is described in detail below using the smart lock using the right-opening door method.

[0075] When unlocking normally, by inputting the correct password, the motor moves the locking member 41 along the guide groove 1111 on the connecting plate 111 and moves into the locking groove 122 of the clutch rotating block 12, so that the clutch seat 11 and the clutch rotating block 12 are connected. At this time, by pressing down the handle body 20, the clutch seat 11 is driven to rotate 30° to 40°, so that the lock tongue of the lock body assembly is separated from the lock groove of the door frame, and the smart lock is opened normally. In this process, the limit member 60 does not contact the limit structure 51. After the handle body 20 is released, under the action of the elastic member 42, the locking member 41 is pushed along the guide groove 1111 away from the locking groove 122, the clutch seat 11 and the clutch rotating block 12 are unlocked, and the smart lock is locked again.

[0076] When the sleeve is used for violent unlocking, the motor does not push the locking member 41 into the locking groove 122, and the clutch seat 11 and the clutch rotating block 12 are not connected as a whole. At this time, if the handle body 20 is lifted, the transmission rod 30 will be reversed through the one side of the arc groove of the clutch seat 11 and the protrusion 121 of the clutch rotating block 12, and the lock tongue of the lock body assembly moves toward the lock groove of the door frame, and it cannot be unlocked. If the downward pressure method is adopted, the clutch seat 11 rotates but the clutch rotating block 12 does not rotate, and the limit member 60 contacts the limit structure 51. If the handle body 20 continues to be rotated, the other side of the arc groove does not drive the protrusion 121, and the clutch seat 11 breaks, that is, the lock body cannot be separated from the lock groove, and the smart lock completes the anti-violent opening.

[0077] When using technical unlocking, the motor does not push the locking piece 41 into the locking groove 122, the clutch seat 11 and the clutch rotating block 12 are not connected as a whole, and due to the action of the flexible connecting piece 13, the clutch rotating block 12 and the clutch seat 11 cannot form a rigid whole, thereby failing to drive the transmission rod 30 to move, that is, the lock tongue of the lock body assembly cannot be separated from the lock groove of the door frame, and the smart lock achieves anti-technical unlocking.
