Description

Technical Field

[0001] The present invention belongs to the technical field of locks, and in particular relates to a lock clutch mechanism and a lock. Background Art

[0002] Smart door locks have been constantly innovating their appearance to meet the demands of the times. Recently, in particular, with the popularity of minimalist styles, there are as few decorative elements on the door as possible. Consequently, the lock that requires a mechanical key to be integrated into the handle, leaving only a handle and a card recognition area or password input area on the outside of the door.

[0003] However, door panels have varying thicknesses in different application scenarios. Existing lock designs, where the lock head is integrated into the handle, are not well suited to installation and commissioning for doors of varying thicknesses. For example, patent CN210714149U discloses a smart door lock that connects the lock tongue and clutch assembly via a square steel bar. However, this structure requires adjusting the length of the square steel bar and lock tongue during installation for door panels of varying thicknesses, increasing commissioning difficulty and cost.

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0066] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment, the lock includes a housing 100 for installation in a door panel 200, and a front handle assembly 4 and a rear handle assembly 8 respectively installed on the front and rear sides of the door panel 200; an identification assembly 6 may also be installed on the door panel 200; a lock head 413 opened by a mechanical key may be integrated on the front handle assembly 4.

[0067] The housing 100 may include a box body 101 and a cover 102 covering an opening of the box body 101 .

[0068] The housing 100 is provided with a lock clutch mechanism 1 , a lock tongue 2 , an unlocking mechanism 3 , a drive module 7 and the like.

[0069] See also Figure 2 、 Figures 4 to 8 , the lock clutch mechanism may include:

[0070] The sleeve 11 is used to drive the unlocking mechanism 3 for controlling the movement of the lock tongue 2; a first through hole 111 is provided in the middle of the sleeve 11, and a first slot 112 is provided on the side wall of the sleeve 11 to communicate with the first through hole 111;

[0071] The front clutch member 12 has an insertion portion 121 at one end that is inserted into the front end of the first through hole 111, and a connecting portion 122 at the other end that is connected to the front handle assembly 4 via a first connecting sleeve 123. A first spring pin 1211 is disposed within the insertion portion 121. The connecting portion 122 can be plugged into the first connecting sleeve 123, and the plug hole on the connecting portion 122 can be adapted to the outer shape of the first connecting sleeve 123, so that the first connecting sleeve 123 can drive the front clutch member 12 to rotate.

[0072] The cylindrical lever 13 is disposed within the first connecting sleeve 123. The interior of the first connecting sleeve 123 may be a circular through hole, allowing the cylindrical lever 13 to rotate about its axis. The front end of the lever 13 is used to connect with the lock head 413 located within the front handle assembly 4. When the lock head 413 rotates, it can drive the lever 13 to rotate. The lever 13 is provided with a circular notch 131 extending along its length.

[0073] For details, see Figure 7 The notch 131 may be a residue left after a portion of the cylindrical rod is removed, and the resulting notch may accommodate the inner end of the first spring pin 1211;

[0074] When the lever 13 is in the first state, the lever 13 at least sequentially passes through the first connecting sleeve 123, the front clutch member 12, and the sleeve 11; the inner end of the first spring pin 1211 is accommodated in the notch of the circular portion 131, and the outer end is accommodated in the body of the front clutch member 12, that is, the sleeve 11 and the front clutch member 12 are in a separated state; and

[0075] When the lock head 413 drives the lever 13 to rotate to the second state, the notch portion 131 pushes the inner end of the first spring pin 1211 to push the outer end of the first spring pin 1211 into the first slot 112 of the sleeve 11, that is, the sleeve 11 and the front clutch member 12 are in a linkage state.

[0076] Specifically, the front end of the sleeve 11 is equipped with a front clutch 12, and the insertion portion 121 of the front clutch 12 is inserted into the first through hole 111 of the sleeve 11 and can rotate relative to the first through hole 111; a first spring pin 1211 is provided on the insertion portion 121; in the "off" state, the first spring pin 1211 does not extend into the first slot 112, that is, the sleeve 11 and the front clutch 12 are in a separated state. At this time, twisting the front handle assembly 4 can only drive the front clutch 12 to rotate idly, and cannot drive the sleeve 11 to rotate, that is, it cannot drive the unlocking mechanism 3 to operate; in the "on" state, the first spring pin 1211 is pushed by the notch 131 and inserted into the first slot 112, that is, the sleeve 11 and the front clutch 12 are in a linked state. At this time, twisting the front handle assembly 4 can drive the front clutch 12 and the sleeve 11 to rotate at the same time, that is, simultaneously drive the unlocking mechanism 3 to operate.

[0077] In this embodiment, the unlocking mechanism 3 can optionally be a connecting rod with one end rotatably disposed within the box body 101 and the other end cooperating with the lock tongue 2. The side of the sleeve 11 can be provided with a protrusion for pushing the unlocking mechanism 3, so that when the sleeve 11 rotates, it can push the unlocking mechanism 3, thereby pulling the lock tongue 2 into the box body 101 to achieve unlocking. Of course, the coordination of the sleeve 11, the unlocking mechanism 3, and the lock tongue 2 can also be achieved using existing technology, and only the linkage of the three can be achieved.

[0078] As a preferred implementation of this embodiment, see Figure 7 The entire lever 13 is cylindrical and can rotate around its axis; a notch 131 can be provided in the middle front portion of the lever 13; because the length of the lever 13 extending into the door panel is different in application scenarios with different door panel thicknesses, in order to adapt to application scenarios with different door panel thicknesses, the notch 131 can be extended a certain distance along the length direction of the lever 13, so that without debugging, the length of the notch 131 can cover the position of the first spring pin 1211 and effectively cooperate with the first spring pin 1211.

[0079] Optionally, the length of the notch portion 131 is 30-50 mm. Preferably, the length of the notch portion 131 is 35-40 mm.

[0080] Preferably, see Figure 7 In the BB cross section, the thickness of the circular portion 131 is smaller than the radius of the lever 13.

[0081] It can be understood that the lever 13 rotates around its axis, so the longer the inner end of the first spring pin 1211 penetrates into the outer circumference of the lever 13, the more the notch 131 can completely push the inner end of the first spring pin 1211 out of the range of the outer circumference of the lever 13, thereby making the displacement of the first spring pin 1211 longer, and thus the length of the first spring pin 1211 penetrating into the first slot 112 can be long enough, so that the front clutch 12 and the sleeve 11 are more stable when rotating together, thereby ensuring the success rate of unlocking.

[0082] In this embodiment, preferably, the lock clutch mechanism also includes a rear clutch 14, one end of which is installed at the rear end of the first through hole 111, and the other end is connected to the rear handle assembly 8 through a second connecting sleeve 141; after the rear clutch 14 is assembled with the sleeve 11, the rear handle assembly 8 is twisted, and the rear clutch 14 and the sleeve 11 can be driven to rotate simultaneously through the second connecting sleeve 141, thereby driving the lock tongue 2 to move through the unlocking mechanism 3.

[0083] Optionally, the outer shape of the first connecting sleeve 123 and the second connecting sleeve 141 can be a triangle, a quadrilateral or other polygon, and a circular hole for accommodating the shift rod 13 can be provided inside; the second connecting sleeve 141 can also be plug-connected to the rear clutch 14.

[0084] In this embodiment, preferably, see Figures 5 to 7 When the lever 13 is in the first state, the rear end of the lever 13 extends into the second connecting sleeve 141. In this embodiment, because the lever 13 needs to rotate about its axis, when the front end of the lever 13 is located in the first connecting sleeve 123 and the rear end is located in the second connecting sleeve 141, the lever 13 can be effectively limited and supported in the radial direction, making the rotation more stable.

[0085] See also Figure 7 The rear end of the lever 13 has a circular segment cross-section (CC cross-section) and a thickness no less than the radius of the lever 13, allowing the rear end of the lever 13 to rotate stably within the second connecting sleeve 141. It is understood that if the thickness of the CC cross-section is less than the radius of the lever 13, the second connecting sleeve 141 will not be able to effectively limit the radial position of the rear end of the lever 13, and it will easily wobble.

[0086] Of course, in other embodiments, the cross-section of the rear end of the lever 13 may be the same as the notch 131. In some scenarios where the door panel is thicker, when the lever 13 is in the first state, the rear end of the lever 13 may not extend into the second connecting sleeve 141.

[0087] It is understandable that the length of the lever 13 can be designed to be at least the length of the first connecting sleeve 123 plus the second connecting sleeve 141. Therefore, a circular notch 131 of sufficient length can be set on the rod body of the lever 13 as needed to adapt to application scenarios with thicker door panels on the market.

[0088] Optional, see Figure 7 A guide slope 132 may be provided on the side of the rear end of the shift rod 13 facing the first spring pin 1211 to facilitate the insertion and extraction of the shift rod 13 during assembly.

[0089] Furthermore, a second slot 113 connected to the first through hole 111 is provided on the side wall of the sleeve 11, and a second spring pin 1131 is provided in the second slot 113; a third slot 124 is provided on the side wall of the insertion portion 121 of the front clutch 12; the second spring pin 1131 is used to be driven by the driving module 7 to be inserted into the third slot 124, so as to connect the sleeve 11 and the front clutch 12 in a linkage state.

[0090] In this embodiment, the drive module 7 may be, but is not limited to, a motor, and may be electrically connected to the control module. After receiving the unlocking instruction, the control module may control the drive module 7 to drive the second spring pin 1131 to insert into the third slot 124, thereby connecting the sleeve 11 to the front clutch member 12.

[0091] See also Figure 8 As an optional embodiment of the front handle assembly 4, the front handle assembly 4 includes: a front handle 41, which includes a handle portion 411 and a rotating shaft portion 412; a lock head 413 connected to the shift rod 13 is provided on the front side of the rotating shaft portion 412; a receiving cavity 414 for accommodating the first connecting sleeve 123 is provided on the rear side of the rotating shaft portion 412; a first spring 415 is provided in the receiving cavity 414, one end of which rests on the front end of the first connecting sleeve 123, and the other end rests on the step on the inner wall of the receiving cavity 414.

[0092] In this embodiment, the cross-sectional shape of the accommodating cavity 414 can match the outer shape of the first connecting sleeve 123 , for example, both are square, so that when the rotating shaft portion 412 rotates, it can drive the first connecting sleeve 123 to rotate.

[0093] In this embodiment, when facing different door panel thicknesses, the first spring 415 can always press the first connecting sleeve 123 against the front clutch member 12, which can adapt to scenarios with different door thicknesses.

[0094] Similarly, the handle of the rear handle assembly 8 may also include a handle portion 411 and a rotating shaft portion 412. A accommodating cavity 414 for accommodating the second connecting sleeve 141 is provided inside the rotating shaft portion 412. A first spring 415 is provided in the accommodating cavity 414, one end of which rests against the rear end of the second connecting sleeve 141, and the other end rests against the inner wall of the accommodating cavity 414.

[0095] Similarly, when facing different door panel thicknesses, the first spring 415 can always press the second connecting sleeve 141 against the rear clutch member 14, which can adapt to scenarios with different door thicknesses.

[0096] In some application scenarios, such as Figure 5 As shown, if the notch 131 is always between the first spring pin 1211 and the inner wall of the first through hole 111, mistaken unlocking may occur in some cases, that is, the lever 13 rotates when unlocking is not required, so that the notch 131 drives the first spring pin 1211 to move.

[0097] Based on this, see Figures 9 to 12 Preferably, the lock head 413 is connected to the lever 13 through the lever retraction mechanism 5; when the lever 13 is in the third state, the front end of the lever 13 is located in the first connecting sleeve 123; the lever retraction mechanism 5 is used to drive the lever 13 from the third state to the first state, and from the first state to the second state under the drive of the lock head 413.

[0098] In this embodiment, the entire unlocking process of the lever 13 goes through the third state, the first state and the second state; and when the lever 13 is in the third state, the front end of the lever 13 is located in the first connecting sleeve 123, and the notch 131 is not between the first spring pin 1211 and the inner wall of the first through hole 111. Therefore, taking the third state as the normal state can greatly reduce the occurrence of accidental unlocking, thereby improving the safety of the lock.

[0099] Specifically, as a preferred embodiment of the lever retracting mechanism 5, the lever retracting mechanism 5 includes:

[0100] The inner cylinder 51 is fixedly connected to the rear end of the lock head 413; a spiral hole 511 is provided on the wall of the inner cylinder 51; the number of the spiral holes 511 can be two;

[0101] The outer cylinder 52 is fixedly mounted within the rotating shaft portion 412 and sleeved around the outer circumference of the inner cylinder 51. The inner cylinder 51 can rotate within the outer cylinder 52. An L-shaped hole is provided on the side wall of the outer cylinder 52. The L-shaped hole includes a longitudinal hole 521 extending from front to rear and a transverse hole 522 communicating with the rear end of the longitudinal hole 521. There can be two L-shaped holes.

[0102] A crossbar 53 connected to the front end of the lever 13; the end of the crossbar 53 is accommodated in the spiral hole 511 and the L-shaped hole; and

[0103] The second spring 54 has two ends respectively against the end of the lock head 413 and the end of the lever 13;

[0104] See also Figure 12 When the lever 13 is in the third state, the end of the crossbar 53 is located at the front end of the spiral hole 511 and the front end of the longitudinal hole 521;

[0105] When the lock head 413 drives the inner cylinder 51 to rotate through the first preset angle, the end of the crossbar 53 moves to the rear end of the longitudinal hole 521 through the engagement of the spiral hole 511 and the longitudinal hole 521. At this time, the lever 13 is in the first state.

[0106] When the lock head 413 continues to drive the inner cylinder 51 to rotate past the second preset angle, the end of the cross bar 53 is driven by the inner cylinder 51 to move along the transverse hole 522 , and at this time, the lever 13 is in the second state.

[0107] Optionally, in some application scenarios, the first preset angle can be 180°; after the lock head 413 drives the inner cylinder 51 to rotate 180°, the lever 13 can move 5 mm, so that the notch 131 is between the first spring pin 1211 and the inner wall of the first through hole 111; the second preset angle can be 90° or 180°, and the notch 131 drives the first spring pin 1211 to unlock.

[0108] Optionally, the rear end of the lever 13 may be as follows Figure 11 As shown, its cross section can be the same as that of the notch portion 131, so as to facilitate insertion when the notch portion 131 moves longitudinally.

[0109] Of course, in other embodiments, the rear end of the lever 13 may also be Figure 7 As shown, the guide slope 132 facilitates the insertion of the notched portion 131 during longitudinal movement. Of course, in this case, the rear end of the lever 13 is prevented from contacting the first spring pin 1211, or the outer end of the first spring pin 1211 is prevented from extending into the first slot 112 due to contact between the rear end of the lever 13 and the first spring pin 1211.

[0110] In this embodiment, optionally, the lock can have a smart lock function, and the lock also includes: a control module; an identification component 6, which is electrically connected to the control module and is used to obtain an unlocking instruction; and a drive module 7, which is electrically connected to the control module; wherein after the control module obtains the unlocking instruction in the identification component 6, the control module controls the drive module 7 to drive the second spring pin 1131 to be inserted into the third slot 124, so as to connect the sleeve 11 and the front clutch 12 in a linkage state.

[0111] Optionally, the identification component 6 may be, but is not limited to, a biometric identification component, such as a fingerprint, iris, lip print, face recognition module, etc.; the identification component 6 may also be an RFID radio frequency card reader module, etc.
