Description

Technical Field

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

[0002] At present, when installing a door lock, the handle direction of the lock structure needs to be installed according to the opening direction of the building door. Most of the lock bodies on the market currently do not have the function of free commutation. Usually, they are divided into left-opening door locks and right-opening door locks according to the left or right opening direction of the door, and are installed respectively according to the corresponding opening directions. Therefore, during production and processing, it is necessary to produce and process lock bodies with two opening directions, resulting in high costs for production, processing, logistics, and warehousing. Moreover, it is very inconvenient for customers to replace them after incorrect purchase, affecting the customer experience. Of course, there are also some lock bodies on the market that can be freely commutated, but when commuting, the lock needs to be disassembled, adjusted, and reinstalled to achieve the commutation function, which consumes the user's energy and affects the stability of the lock body after adjustment, increasing the manufacturer's cost, and there may also be secondary quality accidents due to improper assembly of the lock body by non-professional personnel. Therefore, how to achieve a lock body mechanism with free commutation, a simple and reasonable structure, and a simple and convenient commutation operation is a technical problem urgently to be solved in the industry.

[0003] Chinese Patent Document CN210316847U discloses a lock body mechanism with free commutation, including: a lock box, a free-rotation fork, an upper shaft head, and a lower shaft head; a first accommodation hole penetrates through the upper surface of the lock box, and a second accommodation hole penetrates through the lower surface; the free-rotation fork is arranged in the lock box, and the free-rotation fork penetrates through an accommodation groove; the side wall of the accommodation groove is provided with a pair of first arc grooves and a pair of second arc grooves, and the inner side wall of the accommodation groove is provided with a pair of slots, and the pair of slots are symmetrically distributed about the axis of the free-rotation fork, and the slots communicate with the first arc grooves and the second arc grooves; the upper shaft head extends towards the accommodation groove with a pair of first driving parts, and when the upper shaft head rotates, the upper shaft head drives the free-rotation fork to rotate through the first driving parts. The lower shaft head is rotatably arranged in the second accommodation hole, and a convex platform extends from the upper surface of the lower shaft head into the accommodation groove. A pair of limiting grooves for inserting or pulling out a driving shaft are concavely arranged on the side wall of the convex platform. A pair of second driving parts symmetrically extending about the axis of the convex platform are arranged on the side wall of the convex platform, and the second driving parts are arranged in the second arc grooves. When the driving shaft is inserted into the limiting grooves, when the lower shaft head rotates, the lower shaft head drives the free-rotation fork to rotate through the driving shaft; when the driving shaft is not inserted into the limiting grooves, when the lower shaft head rotates, the second driving parts slide along the second arc grooves, and when the lower shaft head rotates to the edge of the second arc groove, the free-rotation fork can be driven to rotate. The upper shaft head is placed inside the door, and the lower shaft head is placed outside the door. When commutation is required, the upper shaft head and the lower shaft head are taken out, their positions are swapped, and then they are re-attached. However, this technical solution still requires a certain amount of disassembly and assembly work during use, and it is still difficult for ordinary users to install it by themselves.

[0034] Optionally, the biasing force applied to the clutch pin is exerted by a clutch pin spring installed between the clutch pin and the clutch seat, and the clutch pin spring is sleeved on the clutch pin.

[0035] In a second aspect, the present invention provides a lock body, which includes the clutch reversing mechanism according to any one of the foregoing embodiments.

[0036] The technical solution of the present invention has the following advantages:

[0037] 1. In this embodiment, the clutch pin can be externally connected to a motor. When the intelligent lock is successfully verified, the clutch pin can move towards the shaft hole under the drive of the motor so that the clutch pin is inserted into the two clutch grooves, and at the same time, the clutch pin spring is compressed and deformed; after the clutch pin is inserted into the two clutch grooves, an in-rotatable connection is formed between the clutch seat and the transmission component through the clutch pin. By rotating the outer handle fixedly connected to the reversing component, the transmission component and the clutch seat can be driven to rotate, and the rotation of the clutch seat can further drive the lock body to open and close. When the intelligent lock is on standby or the verification is unsuccessful, the clutch pin can extend and reset under the action of the self-elastic force of the clutch pin spring, and drive the clutch pin to move away from the shaft hole so that the clutch pin disengages from the two clutch grooves.

[0038] When the commutation component is moved to the first position corresponding to the first transmission component, the commutation component can be in limit cooperation with the first transmission component, so that the clutch seat is fixedly connected to the first transmission component through the commutation component, and at the same time, the commutation component is disconnected from the second transmission component. At this time, the handle fixedly installed on the first transmission component becomes the inner handle, and the handle fixedly installed on the second transmission component becomes the outer handle. By rotating the inner handle, the first transmission component can be driven to rotate, so as to drive the clutch seat fixedly connected to the first transmission component to rotate, and then the lock body can be driven to open; when the outer handle is rotated, since the commutation component is not connected to the second transmission component, it is also necessary to connect to the second transmission component after the intelligent lock is successfully verified and the clutch pin is inserted into the two clutch grooves before the clutch seat can be driven to rotate by rotating the outer handle, and then the lock body is driven to open; if the intelligent lock is in standby or the verification is unsuccessful, the clutch pin is disengaged from the clutch groove on the second transmission component. At this time, when the outer handle is rotated, the second transmission component can only rotate idly relative to the clutch seat and cannot drive the lock body to open.

[0039] When commutation is required, only need to move the commutation component to the second position corresponding to the second transmission component, the commutation component can be in limit cooperation with the second transmission component, so that the clutch seat is fixedly connected to the second transmission component through the commutation component, and at the same time, the commutation component is disconnected from the first transmission component. At this time, the handle installed on the first transmission component becomes the outer handle, and the handle installed on the second transmission component becomes the inner handle, and the commutation is convenient and fast, without the need for disassembly and assembly.

[0040] 2. The transmission component in the embodiment of the present invention includes a transmission part and a shift shaft that are fixedly installed separately. A clutch groove is formed on the transmission part, and a commutation groove is formed on the shift shaft. The clutch groove and the commutation groove are formed on different parts respectively. Compared with the integral forming method of the transmission component, the processing difficulty can be reduced, the processing rejection rate can be reduced, and thus the production cost can be reduced; in addition, during the use process, when one of the transmission part and the shift shaft is damaged, it can be replaced separately, reducing the maintenance cost.

[0060] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0061] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0062] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0064] As Figures 1 to 7 shown, it should be noted that Figure 5 the arrow direction in the figure is the moving direction of the commutation assembly. An embodiment of the present invention provides a clutch commutation mechanism, which includes a clutch seat 1, a clutch pin 2, two sets of transmission assemblies 3, and a commutation assembly 4.

[0065] The clutch seat 1 is formed with a shaft hole 11 and a pin hole 12 that communicate with each other and form a preset angle; optionally, the pin hole 12 extends along the radial direction of the shaft hole 11.

[0066] The clutch pin 2 is telescopically and movably arranged in the pin hole 12 and is subjected to a biasing force tending to deviate from the shaft hole 11; optionally, the biasing force applied to the clutch pin 2 is applied by a clutch pin spring 6 installed between the clutch pin 2 and the clutch seat 1, and the clutch pin spring 6 is sleeved on the clutch pin 2. The clutch pin 2 is in a stepped column shape along the length direction, and a positioning step is integrally formed on the clutch pin 2. One end of the clutch pin spring 6 abuts against the positioning step, and the other end abuts against the clutch seat 1; a sealing piece 7 for preventing the clutch pin 2 from coming out is arranged at the pin hole 12 of the clutch seat 1. When the clutch pin 2 moves to the limit position in the direction away from the shaft hole 11 under the elastic action of the clutch pin spring 6, the positioning step on the clutch pin 2 can abut against the bottom wall of the sealing piece 7 to limit the clutch pin 2 from continuing to move upward and coming out of the pin hole 12.

[0067] The two sets of transmission components 3 include a first transmission component 301 and a second transmission component 302 respectively available for installing a handle. The two sets of transmission components 3 are installed side by side in the axial direction in the shaft hole 11 of the clutch seat 1 and can both rotate relative to the clutch seat 1; clutch grooves 311 for the clutch pin 2 to insert or disengage are formed on the two sets of transmission components 3; during the telescopic movement of the clutch pin 2, it can insert into or disengage from the two clutch grooves 311 simultaneously.

[0068] The reversing component 4 is movably arranged on the clutch seat 1. The reversing component 4 moves between the positions corresponding to different transmission components 3 and is in limit cooperation with the transmission component 3 at the corresponding position, so as to fix the clutch seat 1 to one of the two sets of transmission components 3.

[0069] In this embodiment, the clutch pin 2 can be externally connected to a motor (not shown in the figure). After the intelligent lock is successfully verified, the clutch pin 2 can move in the direction close to the shaft hole 11 under the drive of the motor so that the clutch pin 2 inserts into the two clutch grooves 311, and at the same time, the clutch pin spring 6 is compressed and deformed; after the clutch pin 2 inserts into the two clutch grooves 311, an in-rotatable connection is formed between the clutch seat 1 and the transmission component 3 through the clutch pin 2. By rotating the outer handle fixedly connected to the reversing component 4, the transmission component 3 and the clutch seat 1 can be driven to rotate, and the rotation of the clutch seat 1 can further drive the lock body to open and close. When the intelligent lock is in standby or the verification is unsuccessful, the clutch pin 2 can reset and extend under the action of the self-elastic force of the clutch pin spring 6, and drive the clutch pin 2 to move in the direction away from the shaft hole 11 so that the clutch pin 2 disengages from the two clutch grooves 311.

[0070] As Figure 6As shown in the figure, when the reversing component 4 is moved to the first position corresponding to the first transmission component 301, the reversing component 4 can be in limit cooperation with the first transmission component 301, so that the clutch seat 1 is fixedly connected to the first transmission component 301 through the reversing component 4, and at the same time, the reversing component 4 is disconnected from the second transmission component 302. At this time, the handle fixedly installed on the first transmission component 301 becomes the inner handle, and the handle fixedly installed on the second transmission component 302 becomes the outer handle. When opening the door by rotating the inner handle, the inner handle can drive the first transmission component 301 to rotate, so as to drive the clutch seat 1 fixedly connected to the first transmission component 301 to rotate, and then the lock body can be driven to open; when opening the door by rotating the outer handle, since the reversing component 4 is not connected to the second transmission component 302, if the intelligent lock is in standby or the verification is unsuccessful, the clutch pin 2 and the clutch groove 311 on the second transmission component 302 are in a disengaged state. At this time, when the outer handle is rotated, the second transmission component 302 can only rotate idly relative to the clutch seat 1 and cannot drive the lock body to open; if the intelligent lock is successfully verified, the clutch pin 2 is inserted into the two clutch grooves 311 and then connected to the second transmission component 302. At this time, the clutch seat 1 can be driven to rotate by rotating the outer handle, and then the lock body can be driven to open.

[0071] When reversing is needed, only the reversing component 4 needs to be moved to the second position corresponding to the second transmission component 302, as Figure 7 shown in the figure, the reversing component 4 can be in limit cooperation with the second transmission component 302, so that the clutch seat 1 is fixedly connected to the second transmission component 302 through the reversing component 4, and at the same time, the reversing component 4 is disconnected from the first transmission component 301. At this time, the handle installed on the first transmission component 301 becomes the outer handle, and the handle installed on the second transmission component 302 becomes the inner handle. The reversing is convenient and fast, and there is no need for disassembly and assembly.

[0072] In this embodiment, the reversing component 4 is axially slidably installed and connected to the clutch seat 1, and has a first position and a second position corresponding to the two groups of transmission components 3 respectively. The reversing component 4 is slidably arranged between the first position and the second position; when the reversing component 4 is in the first position or the second position, it is non-rotatably connected to the corresponding transmission component 3, so as to fix the clutch seat 1 and the transmission component 3 together.

[0073] In this embodiment, the reversing component 4 includes a reversing member 41 and a locking member installed on the reversing member 41.

[0074] The reversing member 41 is slidably mounted in the slideway 13 on the clutch seat 1. Two sets of transmission assemblies 3 are respectively formed with reversing grooves 321 into which the reversing member 41 can be inserted or withdrawn. During the sliding process of the reversing assembly 4 between the first position and the second position, the reversing member 41 can be inserted into the reversing groove 321 on the corresponding transmission assembly 3 and withdrawn from the reversing groove 321 of the other transmission assembly 3. The reversing assembly 4 and the transmission assembly 3 are non-rotatably connected through the cooperation between the reversing member 41 and the reversing groove 321. As Figure 6 and Figure 7 shown, when reversing is required during actual use, a thin rod or other tool can be inserted into the slideway 13 on the clutch seat 1 from either side in the axial direction and act on the reversing member 41 to push the reversing member 41 to slide between the first position and the second position.

[0075] A locking structure 14 is provided on the clutch seat 1. The locking member can be locked or disengaged from the transmission assembly 3 through cooperation with the locking structure 14, so as to limit the reversing member 41 by the locking member to restrict the sliding of the reversing member 41 or release the limit on the reversing member 41. Optionally, the locking member is a locking ball 42 elastically and telescopically mounted on the reversing member 41; the locking structure 14 is a positioning hole formed on the outer peripheral side wall of the clutch seat 1. The positioning hole is communicated with the slideway 13 and cooperates with the locking ball 42. During the sliding process of the reversing assembly 4 between the first position and the second position, the locking ball 42 restricts the reversing member 41 by extending into or withdrawing from the positioning hole, or restricts the reversing member 41 to the first position or the second position. Optionally, the locking ball 42 is elastically connected to the reversing member 41 through a spring 43, and the locking ball 42 is subjected to a biasing force tending to the positioning hole applied by the spring 43.

[0076] Optionally, the slideway 13 is a through groove axially formed on the clutch seat 1, and the reversing groove 321 is a key groove communicated with the through groove and circumferentially limitedly cooperating with the reversing member 41; the distance between the reversing groove 321 on one transmission assembly 3 and the reversing groove 321 on the other transmission assembly 3 is greater than the length of the reversing member 41 in its sliding direction.

[0077] In this embodiment, the two sets of transmission assemblies 3 have the same structure and both include a transmission member 31 and a shift shaft 32. The transmission member 31 is rotatably arranged in the shaft hole 11 of the clutch seat 1; the shift shaft 32 and the transmission member 31 are non-rotatably connected through a non-circular fitting structure 33 and are suitable for installing a handle. The transmission assembly 3 in this embodiment includes a transmission member 31 and a shift shaft 32 that are fixedly installed separately. During use, when one of the transmission member 31 and the shift shaft 32 is damaged, it can be replaced separately, reducing the maintenance cost.

[0078] Optionally, on the circumferential side wall at one end of each of the two transmission members 31, a clutch groove 311 corresponding to the pin hole 12 is formed, and the two clutch grooves 311 are connected to form a pin slot; during the telescopic movement of the clutch pin 2, it can be inserted into or disengaged from the pin slot to achieve simultaneous insertion into or simultaneous disengagement from the two clutch grooves 311. Optionally, the reversing groove 321 is formed on the outer peripheral wall of the shifting shaft 32. In this embodiment, the transmission assembly 3 is installed in a split manner, and the clutch groove 311 is formed on the transmission member 31, and the reversing groove 321 is formed on the shifting shaft 32. The clutch groove 311 and the reversing groove 321 are formed on different parts respectively. Compared with the integral forming method of the transmission assembly 3, the processing difficulty can be reduced, the processing scrap rate can be reduced, and thus the production cost can be reduced.

[0079] Optionally, the shifting shaft 32 is formed with a non-circular fitting portion for fixedly installing the handle rotating shaft; optionally, the non-circular fitting portion is a fitting groove 322 formed on the shifting shaft 32, and the inner cavity cross-section of the fitting groove 322 is non-circular. The rotating shaft of the handle is inserted and fitted into the fitting groove 322 on the shifting shaft 32 to form a non-rotatable connection between the two.

[0080] Optionally, a bearing 5 is provided between the transmission assembly 3 and the clutch seat 1; the inner ring of the bearing 5 is installed on the outer peripheral wall of the non-circular fitting structure 33, and the outer ring of the bearing 5 is installed on the inner peripheral wall of the shaft hole 11 of the clutch seat 1.

[0081] In the second embodiment as Figures 8 to 9 shown, the transmission assembly 3 is an integrally formed structure. A bearing 5 is provided between the outer peripheral wall of the transmission assembly 3 and the inner wall of the shaft hole 11 of the clutch seat 1; a positioning step suitable for axially positioning the bearing 5 is formed on the inner wall of the shaft hole 11 of the clutch seat 1. Along the length direction of the shaft hole 11, the bearing 5 abuts between the positioning step and the side wall of the transmission assembly 3 facing the positioning step.

[0082] The embodiment of the present invention also provides a lock body, and this lock body includes the clutch reversing mechanism in any one of the foregoing embodiments. The lock body provided by the present invention includes the foregoing clutch reversing mechanism. Among them, the technical advantages and effects achieved by this lock body also include the technical advantages and effects achieved by the clutch reversing mechanism, which will not be elaborated here.

[0083] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
