Description

Technical Field

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

[0002] Electronic locks generally use a clutch mechanism to unlock and lock the lock. However, when the electronic lock is subjected to vibration or knocked from bottom to top, the clutch pin in the electronic lock may be affected by the impact and move upward and lock with the handle connection seat and clutch core. If the handle is turned at this time, it can be unlocked. If the knocking frequency is increased, the probability of unlocking is higher, resulting in the risk of illegal unlocking of the electronic lock. Summary of the invention

[0003] The embodiment of the present application discloses a clutch mechanism and a lock, which can keep the handle connecting seat and the clutch core in a separated state when the lock is vibrated or knocked, thereby effectively preventing the risk of illegal unlocking.

[0004] In order to achieve the above-mentioned purpose, in a first aspect, the present application discloses a clutch mechanism, which is applied to a lock having a lock core, and the clutch mechanism comprises:

[0005] A handle connection base, wherein the handle connection base has an installation space, and the installation space has a first opening;

[0006] A clutch core, the clutch core is disposed around at least a portion of the outer periphery of the handle connection seat, the clutch core has a slide groove portion, the slide groove portion has a second opening, the second opening is connected to the first opening in a first direction, and the clutch core is configured to be transmission-connected to the lock core;

[0007] A first engaging member, wherein the first engaging member is movably disposed in the installation space along the first direction;

[0008] a second engaging member, the second engaging member being movably disposed on the slide groove portion along the first direction, and the second engaging member and the first engaging member being spaced apart in the first direction;

[0009] A driving member, the driving member is arranged on a side of the second engaging member away from the first engaging member, the driving member is used to drive the second engaging member to enter the installation space through the first opening to engage with the first engaging member;

[0010] The first engaging member has an engaged state and a free state;

[0011] In the engaged state, the second engaging member enters the installation space through the first opening and engages with the first engaging member, so that the handle connecting seat and the clutch core are coupled;

[0012] In the free state, the first engaging member moves away from the first opening along the first direction, the second engaging member enters the installation space through the first opening, and the first engaging member and the second engaging member are spaced apart in the first direction.

[0013] In the clutch mechanism provided in the present application, the handle connection seat is provided with an installation space having a first opening, and the clutch core is provided with a slide groove portion having a second opening, and the first opening and the second opening are connected in the first direction. A first bite member movable along the first direction is provided in the installation space, and a second bite member movable along the first direction is provided in the slide groove portion, and the second bite member is also spaced apart from the first bite member in the first direction, and a driving member is provided on the side of the second bite member away from the first bite member, and the driving member is used to drive the second bite member to move toward the first bite member. The first bite member has an engaged state and a free state. In the engaged state, the driving member drives the first bite member to move along the first direction and engage with the second bite member, thereby coupling the handle connection seat and the clutch core, so that the clutch core cannot rotate relative to the handle connection seat. At this time, rotating the handle connection seat can drive the lock core to unlock. In the free state, the first bite member moves away from the first opening along the first direction. When the second bite member enters the installation space, the second bite member and the first bite member are spaced apart in the first direction, so that the second bite member cannot engage with the first bite member. At this time, rotating the handle connecting seat cannot drive the clutch core to rotate, and the lock core cannot be driven, and thus the lock cannot be unlocked. In this way, when the driving member of the lock equipped with the clutch mechanism does not work and is vibrated or knocked, the first bite member is in the free state, and the first bite member and the second bite member are spaced apart, so that the handle connecting seat and the clutch core cannot be coupled, so that vibration or knocking cannot be achieved to unlock, which can effectively prevent the risk of illegal unlocking.

[0014] As an optional embodiment, the handle connecting seat includes a first bottom wall portion and a first side wall portion, the first side wall portion is enclosed and connected to the first bottom wall portion to enclose the installation space between the first bottom wall portion, and the first side wall portion is provided with the first opening;

[0015] The first bottom wall portion is provided with a first limiting portion and a second limiting portion which are arranged opposite to and spaced from each other along the second direction, a movable position is constructed between the first limiting portion and the second limiting portion, and the first engaging member is movably arranged at the movable position, so that the first engaging member can move relative to the first limiting portion and the second limiting portion along the first direction;

[0016] The second direction is perpendicular to the first direction.

[0017] By arranging the first limiting portion and the second limiting portion on the first bottom wall portion along the second direction at intervals, and using the first limiting portion and the second limiting portion to construct an active position, the first engaging member is located in the active position constructed by the first limiting portion and the second limiting portion, and the first limiting portion and the second limiting portion can be used to limit the first engaging member in the second direction to ensure that the first engaging member and the second engaging member can be aligned in the second direction, thereby ensuring that the first engaging member and the second engaging member can engage normally when the lock is normally unlocked.

[0018] As an optional implementation, in the second direction, the first side wall portion is provided with a first protruding portion protruding from the first limiting portion, and a second protruding portion protruding from the second limiting portion;

[0019] The first protrusion and the second protrusion are arranged at intervals to form the first opening;

[0020] In the second direction, a first stop portion is provided on one side of the first bite member, and a second stop portion is provided on the other side of the first bite member, and the first protrusion and the second protrusion are used to cooperate with the first stop portion and the second stop portion to prevent the first bite member from leaving the active position.

[0021] By arranging the first protrusion and the second protrusion which are spaced along the second direction and constitute the first opening on the second side wall portion, and respectively corresponding the first stop portion and the second stop portion on both sides of the first engaging part along the second direction, the first protrusion and the second protrusion cooperate with the first stop portion and the second stop portion to prevent the first engaging part from being separated from the active position at the first opening and engaging with the second engaging part, thereby avoiding unexpected unlocking.

[0022] As an optional embodiment, the handle connecting seat further comprises an annular wall portion provided on the first bottom wall portion and located in the installation space, the annular wall portion and the first opening are arranged opposite to each other in the first direction, the first limiting portion and the second limiting portion are located at the outer periphery of the annular wall portion, and the first limiting portion and the second limiting portion are connected to the annular wall portion, and the active position is constructed between the first limiting portion, the second limiting portion and the annular wall portion;

[0023] The clutch mechanism further includes a first elastic member, which is disposed between the annular wall portion and the first engaging member. When the first engaging member moves along the first direction to deform the first elastic member, the first elastic member applies a reverse force to the first engaging member.

[0024] When the lock is struck or vibrated, causing the first engaging member to move in the first direction, the first engaging member moves to press against the first elastic member, causing the first elastic member to be compressed. When the impact of the strike or vibration disappears, the first elastic member applies an elastic force to the first engaging member, causing the first engaging member to reset. Thus, the elastic member can be used to automatically reset the first engaging member without manual reset, and the reset method is simpler and more effective.

[0025] As an optional embodiment, the first elastic member is a spring sheet, which has a first side and a second side relative to each other along the thickness direction, the first limiting portion is provided with a first bearing surface, and the second limiting portion is provided with a second bearing surface, the first side abuts against the first bearing surface and the second bearing surface, and the second side faces the annular wall portion.

[0026] The first elastic member is set as a spring sheet, and the first and second bearing surfaces are respectively provided on the first limiting portion and the second limiting portion to support the spring sheet, so that the size of the clutch mechanism in the first direction can be reduced. At the same time, the spring sheet is limited by the annular wall portion and the two bearing surfaces, which can simplify the overall structure of the clutch mechanism, facilitate assembly, and reduce production costs.

[0027] As an optional embodiment, the first engaging member has a first end and a second end opposite to each other along the first direction, the first end is provided with an engaging portion, the engaging portion is used to engage with the second engaging member, and the second end has an end surface facing the annular wall portion, and the end surface is recessed toward the first end.

[0028] By making the end surface of the second end of the first bite member concave toward the first end, so that the second end of the first bite member forms protrusions on both sides along the second direction, when the first bite member moves along the first direction and presses the spring sheet, because the second side of the spring sheet faces and abuts the annular wall portion, the protrusions on both sides of the second end of the first bite member can drive the spring sheet to bend, so that the spring sheet stores elastic potential energy and provides a reset elastic force for the first bite member to reset. At the same time, the concave at the second end of the first bite member can be nested with the annular wall portion, which can reduce the size of the clutch mechanism in the first direction, and help to achieve a miniaturized design of the clutch mechanism.

[0029] As an optional implementation, there are two installation spaces, two first openings and two first engaging parts, the two installation spaces and the two first openings are symmetrically arranged along the first direction, and the two first engaging parts are symmetrically arranged along the first direction and are arranged one by one in the two installation spaces.

[0030] By setting the number of installation spaces, the first opening and the first engaging parts to two, and the two installation spaces, the two first openings and the two first engaging parts are symmetrically arranged, when the clutch mechanism is applied to doors and windows of different directions (left opening, right opening), it is only necessary to rotate the second engaging part to cooperate with different first engaging parts to meet the needs of doors and windows of different directions.

[0031] As an optional embodiment, the clutch mechanism also includes a second elastic member, the clutch core is provided with a third limiting portion spaced apart from the second engaging member, the second engaging member is provided with a fourth limiting portion, the third limiting portion and the fourth limiting portion are spaced apart along the first direction, the second elastic member is located between the third limiting portion and the fourth limiting portion, one end of the second elastic member abuts against the third limiting portion, and the other end of the second elastic member abuts against the fourth limiting portion; the second elastic member is used to provide a reset elastic force to the second engaging member when the second engaging member moves toward the first engaging member.

[0032] By arranging a third limit portion on the clutch core, arranging a fourth limit portion on the second bite member, the third limit portion and the fourth limit portion are arranged at intervals along the first direction, and arranging a second elastic member between the third limit portion and the fourth limit portion, when the user unlocks the lock, the second bite member moves along the first direction and compresses the second elastic member, and when the user completes the unlocking, the elastic force of the second elastic member drives the second bite member to reset, so that the lock can automatically complete the locking. In addition, when the impact on the lock makes the force of the second bite member on the second elastic member smaller than the elastic force of the second elastic member, the second elastic member can also prevent vibration unlocking.

[0033] In a second aspect, the present application provides a clutch mechanism, which is applied to a lock having a lock core, and the clutch mechanism includes:

[0034] A handle connection base, wherein the handle connection base has an installation space, and the installation space has a first opening;

[0035] A clutch core, the clutch core is arranged around at least a portion of the outer periphery of the handle connecting seat, the clutch core has a slide groove portion, the slide groove portion has a second opening, and the second opening is connected to the first opening; the clutch core is transmission-connected to the lock core;

[0036] A first engaging member, wherein the first engaging member is movably disposed in the installation space along a first direction;

[0037] A second engaging member, the second engaging member being movably disposed on the slide groove portion along the first direction;

[0038] A driving member is arranged on a side of the second engaging member away from the first engaging member, and is used to drive the second engaging member to enter the installation space through the first opening and engage with the first engaging member, so as to couple the handle connecting seat and the clutch core.

[0039] The handle connection seat is provided with an installation space having a first opening, and the clutch core is provided with a slide groove portion having a second opening, and the first opening is communicated with the second opening. A first bite member movable along a first direction is provided in the installation space, and a second bite member movable along a first direction is provided in the slide groove portion, and a driving member is provided on a side of the second bite member away from the first bite member, and the driving member is used to drive the second bite member to move toward the first bite member. When the user unlocks the lock, the driving member can move the second bite member along the first direction until it is engaged with the second bite member, and at this time, the handle connection seat is coupled with the clutch core, and the user can complete the unlocking by turning the handle connection seat. When the lock is knocked or vibrated, the first bite member and the second bite member are both impacted and move synchronously along the first direction, so that the first bite member and the second bite member remain separated, and at this time, the handle connection seat and the clutch core remain separated, and even if the handle connection seat is turned, the lock cannot be unlocked, thereby preventing the lock from being illegally unlocked when it is vibrated or impacted.

[0040] In a second aspect, the present application discloses an electronic lock, which includes any one of the above-mentioned clutch mechanisms.

[0041] Compared with the prior art, the beneficial effects of this application are:

[0042] In the clutch mechanism provided in the present application, the handle connection seat is provided with an installation space having a first opening, and the clutch core is provided with a slide groove portion having a second opening, and the first opening and the second opening are connected in the first direction.

The first bite member has an engaged state and a free state. In the engaged state, the driving member drives the first bite member to move along the first direction and engage with the second bite member, thereby coupling the handle connection seat and the clutch core, so that the clutch core cannot rotate relative to the handle connection seat. At this time, rotating the handle connection seat can drive the lock core to unlock. In the free state, the first bite member moves away from the first opening along the first direction. When the second bite member enters the installation space, the second bite member and the first bite member are spaced apart in the first direction, so that the second bite member cannot engage with the first bite member. At this time, rotating the handle connecting seat cannot drive the clutch core to rotate, and the lock core cannot be driven, and thus the lock cannot be unlocked. In this way, when the driving member of the lock equipped with the clutch mechanism does not work and is vibrated or knocked, the first bite member is in the free state, and the first bite member and the second bite member are spaced apart, so that the handle connecting seat and the clutch core cannot be coupled, so that vibration or knocking cannot be achieved to unlock, which can effectively prevent the risk of illegal unlocking.

[0072] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0073] In the present application, the directions or positional relationships indicated by the terms "upper", "front", "back", "top", "inner", "outer", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0074] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0075] In addition, the term "disposed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0076] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0077] In the electronic lock, the handle connection seat of the clutch mechanism is connected to the handle on one side and arranged opposite to the clutch core on the other side. The clutch core can rotate relative to the handle connection seat, and the clutch core is provided with a square rod that cooperates with the lock body and the lock tongue. A clutch pin and a motor for driving the clutch pin to move are arranged below the handle connection seat. When the motor is not working, the clutch pin is separated from the handle connection seat and the clutch core. At this time, when the handle is turned, the handle connection seat rotates relative to the clutch core, that is, it is idle, and the lock cannot be unlocked. When an electronic key (such as fingerprint, password, face, iris, etc.) or a rotating mechanical key is used to drive the motor, the clutch pin is driven to move upward through the push rod of the motor, so that the clutch pin cooperates with the handle connection seat and the clutch core to lock, the clutch core and the handle are linked, and the handle is turned. The clutch core can be driven to rotate through the handle, so that the square rod drives the lock body and the lock tongue to achieve unlocking. When the lock is closed, the push rod of the motor and the clutch pin are reset, and the handle connection seat and the clutch core are no longer linked. However, if a wooden hammer or other tool is used to knock on the motor lock, the clutch pin may move upward under the action of the knock, causing the handle connecting seat and the clutch core to lock together. If the handle connecting seat is turned at this time, the lock can be unlocked, that is, the existing electronic lock is at risk of being illegally unlocked.

[0078] In order to solve the potential risk of illegal unlocking of the electronic lock, the inventor sets a connecting component between the motor and the clutch pin to connect the motor drive shaft and the clutch pin. The motor drive shaft drives the clutch pin to move to the handle connection seat to lock by lifting the connecting component. When the electronic lock is knocked, the clutch pin is restricted by the connecting component and cannot move to the handle connection seat. In order for the handle connection seat to rotate normally, the clutch pin needs to be able to rotate a certain range relative to the connecting component, which makes the structure of the connecting component more complicated and larger in size, resulting in a complex structure of the electronic lock, high manufacturing cost, large size, and limited application scenarios.

[0079] In view of the defects that still exist in the related designs of electronic locks, the present application provides a clutch mechanism, which is applied to a lock with a lock core, wherein the handle connection seat of the clutch mechanism is provided with an installation space having a first opening, and the clutch core is provided with a slide groove portion having a second opening, and the first opening and the second opening are connected. A first bite member that can move along a first direction is provided in the installation space, a second bite member that can move along the first direction is provided in the slide groove portion, and a driving member is provided on the side of the second bite member away from the first bite member, and the driving member is used to drive the second bite member to move toward the first bite member. The first bite member has an engaged state and a free state. In the engaged state, the driving member drives the first bite member to move along the first direction and engage with the second bite member, thereby coupling the handle connection seat and the clutch core, so that the clutch core cannot rotate relative to the handle connection seat. At this time, rotating the handle connection seat can drive the lock core to unlock. In the free state, the first engaging member moves away from the first opening in the first direction, and the second engaging member cannot engage with the first engaging member when entering the installation space. At this time, rotating the handle connecting seat cannot drive the clutch core to rotate, and thus cannot drive the lock core, and thus cannot unlock. In this way, when the driving member of the lock equipped with the clutch mechanism does not work and is vibrated or knocked, the first engaging member is in the free state, and the first engaging member and the second engaging member are spaced apart, so that the handle connecting seat and the clutch core cannot be coupled, and thus vibration or knocking unlocking cannot be achieved, which can effectively prevent the risk of illegal unlocking.

[0080] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0081] See also Figures 1 to 7 , Figure 1 is a three-dimensional structural schematic diagram of the clutch mechanism of an embodiment of the present application, Figure 2 is a schematic diagram of a state in which the first engaging member is in a separated state in an embodiment of the present application, Figure 3 is a schematic diagram of the state when the first engaging member is in the engaged state in the embodiment of the present application, Figure 4 is a schematic diagram of the state when the first engaging member is in a free state in the embodiment of the present application, Figure 5 is a schematic diagram of the structure explosion of the clutch mechanism disclosed in this embodiment, Figure 6 is a schematic diagram of the internal structure assembly of the handle connecting base disclosed in this embodiment, Figure 7 It is a schematic diagram of the three-dimensional structure of the handle connecting seat disclosed in the embodiment of the present application.

[0082] The clutch mechanism 1 of the embodiment of the present application includes: a handle connecting seat 11, a clutch core 12, a first bite member 13, a second bite member 14 and a driving member 15.

[0083] The handle connecting base 11 has an installation space 111 . The installation space 111 has a first opening 111 a . The first engaging member 13 is movably disposed in the installation space 111 along the first direction P1 .

[0084] The clutch core 12 is disposed around at least part of the outer periphery of the handle connection base 11, and has a slide groove portion 121, and the slide groove portion 121 has a second opening 121a connected to the first opening 111a in the first direction P1, and the second engaging member 14 is movably disposed in the slide groove portion 121 along the first direction P1, and is spaced apart from the first engaging member 13 in the first direction P1. In addition, the clutch core 12 is drivingly connected to the lock core of the lock.

[0085] The driving member 15 is disposed on a side of the second engaging member 14 away from the first engaging member 13 . The driving member 15 is used to drive the second engaging member 14 to enter the installation space 111 from the first opening 111 a and engage with the first engaging member 13 , so that the handle connecting seat 11 and the clutch core 12 are coupled.

[0086] When the handle connecting base 11 and the clutch core 12 are coupled, the handle connecting base 11 is rotated, and the handle connecting base 11 drives the clutch core 12 to rotate through the first bite member 13 and the second bite member 14, and then the clutch core 12 drives the lock core to move, so that the lock can be unlocked.

[0087] When the first bite member 13 and the second bite member 14 are separated, the handle connecting seat 11 and the clutch core 12 are decoupled. If the handle connecting seat 11 is rotated, the rotation of the handle connecting seat 11 cannot be transmitted to the clutch core 12 due to the separation of the first bite member 13 and the second bite member 14, so that the clutch core 12 remains relatively still. At this time, the handle connecting seat 11 is idling and the lock cannot be unlocked.

[0088] When the first bite member 13 and the second bite member 14 are separated, if the lock is struck with a hammer or other tool, the first bite member 13 and the second bite member 14 are subjected to the impact of the strike or vibration, and move along the first direction P1, so that the first bite member 13 and the second bite member 14 remain separated, and the handle connecting seat 11 and the clutch core 12 remain in a decoupled state. If the handle connecting seat 11 is rotated, the clutch core 12 cannot be driven to rotate synchronously, and the lock cannot be unlocked. It can be seen that the lock using the clutch mechanism 1 provided by the present application can remain locked when struck or vibrated, effectively preventing the risk of illegal unlocking.

[0089] It can be seen that the first bite member 13 has different states, such as the separated state when the first bite member 13 and the second bite member 14 remain separated and are both at rest, the engaged state when the first bite member 13 and the second bite member 14 are engaged, and the free state when the first bite member 13 and the second bite member 14 remain separated during movement.

[0090] Normally, the first engaging member 13 is in a separated state, for example Figure 5 As shown, the first bite member 13 and the second bite member 14 are separated from each other and are in a stationary state, that is, although the first bite member 13 is arranged close to the first opening 111a at this time, the second bite member 14 has not entered the first opening 111a, and therefore the two do not bite each other. At this time, the lock is in a locked state. When the user needs to unlock the lock, a specific key (such as fingerprint, password, face, iris, mechanical key, etc.) can be used to trigger the driving member 15, so that the driving member 15 drives the second bite member 14 to move along the first direction P1, and successively passes through the second opening 121a and the first opening 111a and enters the installation space 111. The second bite member 14 moves to bite with the first bite member 13, as shown in FIG. Figure 6 At this time, the first engaging member 13 is in an engaged state, and the user rotates the handle connecting seat 11 to enable the clutch core 12 to drive the lock core to unlock the lock.

[0091] When the first engaging member 13 and the second engaging member 14 are separated from each other, that is, when the lock is in a locked state, if a hammer or other heavy object is used to hit the lock, then at this time, the first engaging member 13 and the second engaging member 14 are both moved along the first direction P1 by the impact, that is, the first engaging member 13 moves along the first direction P1 to move away from the first opening 111a, and even if the second engaging member 14 is forced to enter the first opening 111a, the first engaging member 13 is far away from the first opening 111a, so that the second engaging member 14 and the first engaging member 13 cannot engage, that is, the two remain separated. For example, Figure 7 As shown, at this time, the first engaging member 13 is in a free state. If the user rotates the handle connecting seat 11 at this time, the clutch core 12 will not be rotated by the handle connecting seat 11, thereby preventing illegal unlocking.

[0092] Optionally, the first direction P1 may be any direction. The following description will be given by taking the first direction P1 as a height direction as an example, but it does not mean that the following settings are only applicable to this example.

[0093] The specific structure of the clutch mechanism will be described in detail below with respect to different states of the first engaging member and the second engaging member.

[0094] In some embodiments, the first engaging member 13 and the second engaging member 14 can both be configured as block-shaped members or strip-shaped members, and the engagement between the two can be achieved through matching grooves and protrusions.

[0095] In some embodiments, in order to make the first engaging member 13 more easily enter the free state when the lock is vibrated or knocked, the first engaging member 13 can be set as a member with a relatively small weight, for example, the first engaging member 13 can be set as a plastic member. In this way, since the density of plastic is relatively small, it has a relatively small weight under the condition of equal volume. When the lock is vibrated or knocked, the first engaging member 13 can move along the first direction P1 under a relatively small impact, thereby remaining separated from the second engaging member 14.

[0096] In some embodiments, in order to keep the second engaging member 14 separated from the first engaging member 13 when the lock is vibrated or knocked, the second engaging member 14 can be set as a heavy component. For example, the second engaging member 14 can be set as a metal component such as steel, copper, or a high-density alloy material component such as stainless steel, so that the second engaging member 14 can move along the first direction P1 only when the impact is large enough.

[0097] The specific structure of the handle connecting seat is introduced below.

[0098] In some embodiments, the handle connecting base 11 may include a rotating base 112 and a connecting rod 113. The rotating base 112 is sleeved with the clutch core 12, and the connecting rod 113 is connected to the rotating base 112. The connecting rod 113 is used to connect to the handle of the lock. The user rotates the handle of the lock to drive the connecting rod 113 to rotate, so that the connecting rod 113 can drive the rotating base 112 to rotate, thereby realizing the unlocking action.

[0099] In some embodiments, the rotating seat 112 is generally cylindrical, and the connecting rod 113 can be coaxially fixedly connected to the rotating seat 112. Optionally, the rotating seat 112 can be integrally provided with the connecting rod 113, and the rotating seat 112 can also be fixedly connected to the connecting rod 113 by welding, screwing, clamping, etc.

[0100] Optionally, the rotating seat 112 may be a cylindrical open shell, and the connecting rod 113 may be disposed on a side of the rotating seat 112 away from the opening thereof, that is, the connecting rod 113 is located in the external space of the rotating seat 112 .

[0101] Please also see Figure 8 and Fig. 9 , Figure 8 is a front view schematic diagram of the handle connecting base in the embodiment of the present application, Fig. 9 It is a schematic diagram of the assembly of the first elastic member in the embodiment of the present application.

[0102] In some embodiments, the rotating seat 112 includes a first bottom wall portion 114 and a first side wall portion 115, and the first side wall portion 115 is disposed around the first bottom wall portion 114 and connected to the first bottom wall portion 114. The first bottom wall portion 114 and the first side wall portion 115 together form an installation space 111, and the first side wall portion 115 is provided with the first opening 111a.

[0103] In some embodiments, the first bottom wall portion 114 can be a circular plate-shaped component, and the first side wall portion 115 is arranged around the circular contour and connected to the first bottom wall portion 114. Since the first side wall portion 115 is provided with a first opening 111a, the first bottom wall portion 114 and the first side wall portion 115 construct a cylindrical trough body with the first opening 111a.

[0104] In some embodiments, the first bottom wall portion 114 is provided with a first limiting portion 114a and a second limiting portion 114b that are opposite and spaced apart along the second direction P2, a movable position 114c is formed between the first limiting portion 114a and the second limiting portion 114b, and the first engaging member 13 is movably disposed at the movable position 114c relative to the first limiting portion 114a and the second limiting portion 114b along the first direction P1. The second direction P2 is perpendicular to the first direction P1. With such arrangement, the first limiting portion 114a and the second limiting portion 114b can be used to limit the first engaging member 13 in the second direction P2, so that the first engaging member 13 cannot move in the second direction P2 relative to the first limiting portion 114a and / or the second limiting portion 114b, thereby avoiding misalignment of the first engaging member 13 and the second engaging member 14 in the second direction P2, ensuring that the first engaging member 13 and the second engaging member 14 can be aligned in the second direction P2, thereby ensuring that the first engaging member 13 and the second engaging member 14 can engage normally during normal unlocking.

[0105] It can be understood that when the first direction P1 is a height direction, the second direction P2 is a horizontal direction.

[0106] The first position-limiting portion 114a and the second position-limiting portion 114b may be constructed as a protruding structure protruding from the surface of the first bottom wall portion 114, similar to the first side wall portion 115. The first position-limiting portion 114a and the second position-limiting portion 114b are located in the space surrounded by the first side wall portion 115, and the first position-limiting portion 114a and the second position-limiting portion 114b at least have a portion extending along the first direction P1. In this way, in the second direction P2, the interval between the first position-limiting portion 114a and the second position-limiting portion 114b may form the above-mentioned active position 114c.

[0107] In addition, the structure of the handle connecting base 11 can be strengthened by using the first limiting portion 114 a and the second limiting portion 114 b , so that the handle connecting base 11 has sufficient structural strength.

[0108] In some embodiments, the first side wall portion 115 is connected to the first limiting portion 114a and the second limiting portion 114b, so that the first bottom wall portion 114, the first limiting portion 114a, the second limiting portion 114b and the first side wall portion 115 together form an active position 114c.

[0109] Optionally, the first bottom wall portion 114, the first position limiting portion 114a, the second position limiting portion 114b and the first side wall portion 115 may be independent components or integrally formed components, or part of the first bottom wall portion 114, the first position limiting portion 114a, the second position limiting portion 114b and the first side wall portion 115 may be independent components and part of them may be integral components. The following description will be made by taking the first bottom wall portion 114, the first position limiting portion 114a, the second position limiting portion 114b and the first side wall portion 115 as an integral component as an example, but it does not mean that the following configuration is only applicable to this example.

[0110] In some embodiments, in the second direction P2, the first side wall portion 115 is provided with a first protrusion 115a protruding from the first limiting portion 114a, and a second protrusion 115b protruding from the second limiting portion 114b, and the first protrusion 115a and the second protrusion 115b are arranged at intervals to construct the above-mentioned first opening 111a.

[0111] It can be understood that the distance between the first limiting portion 114a and the second limiting portion 114b in the second direction P2 is greater than the distance between the first protruding portion 115a and the second protruding portion 115b in the second direction P2. That is, the first opening 111a is retracted relative to the active position 114c in the second direction P2. The first protruding portion 115a and the second protruding portion 115b can prevent the first engaging member 13 from escaping from the active position 114c from the first opening 111a, thereby preventing the clutch mechanism 1 from failing.

[0112] In some embodiments, in the second direction P2, a first stopper 131 is disposed on one side of the first engaging member 13, and a second stopper 132 is disposed on the other side of the first engaging member 13, and the first stopper 131 and the second stopper 132 protrude from the surface of the remaining portion of the first engaging member 13 in the second direction P2. That is, the distance between the surface of the first stopper 131 and the surface of the second stopper 132 in the second direction P2 is greater than the distance between the two side surfaces of the remaining portion of the first engaging member 13 in the second direction P2.

[0113] It can be understood that the first stop portion 131 and the first protrusion 115a are correspondingly arranged, and the second stop portion 132 and the second protrusion 115b are correspondingly arranged. When the first bite member 13 moves along the first direction P1 toward the first opening 111a, the first protrusion 115a abuts against the first stop portion 131, and the second protrusion 115b abuts against the second stop portion 132, so that the first bite member 13 cannot be separated from the active position 114c through the first opening 111a, thereby preventing the first bite member 13 from separating from the active position 114c from the first opening 111a and engaging with the second bite member 14, thereby avoiding unexpected unlocking.

[0114] In some embodiments, the size of the portion of the first engaging member 13 provided with the first stopper 131 and the second stopper 132 in the second direction P2 is equal to or slightly smaller than the size of the active position 114c in the second direction P2, and the size of the portion of the first engaging member 13 not provided with the first stopper 131 and the second stopper 132 in the second direction P2 is equal to or slightly smaller than the size of the first opening 111a in the second direction P2. In this way, the portion of the first engaging member 13 not provided with the first stopper 131 and the second stopper 132 can move to the first opening 111a to reduce the distance that the second engaging member 14 moves to engage with the first engaging member 13 after passing through the first opening 111a.

[0115] In some embodiments, when the first stopper 131 and the second stopper 132 are respectively in contact with the first protrusion 115 a and the second protrusion 115 b , the end of the first engaging member 13 facing the second engaging member 14 may be flush with the outer contour of the first bottom wall 114 .

[0116] It is understandable that the first stop portion 131 and the second stop portion 132 can both be convex strips or convex blocks protruding from the first engaging member 13 .

[0117] Please see again Figure 8 In some embodiments, the handle connecting seat 11 also includes an annular wall portion 116 arranged on the first bottom wall portion 114 and located in the installation space 111, the annular wall portion 116 and the first opening 111a are arranged opposite to each other in the first direction P1, the first limiting portion 114a and the second limiting portion 114b are located on the outer periphery of the annular wall portion 116, and the first limiting portion 114a and the second limiting portion 114b are connected to the annular wall portion 116, and an active position 114c is constructed between the first limiting portion 114a, the second limiting portion 114b and the annular wall portion 116.

[0118] It can be understood that when the first bottom wall portion 114 can be set as a circular plate, the annular wall portion 116 can be set concentrically with the first bottom wall portion 114, that is, the positive projection of the annular wall portion 116 on the first bottom wall portion 114 is a circle, and is concentric with the contour of the first bottom wall portion 114.

[0119] It can be understood that the annular wall portion 116 can be provided corresponding to the connecting rod 113 , that is, a through hole penetrating to the annular wall portion 116 can be provided on the connecting rod 113 , so that the through hole can be connected to the corresponding through hole on the clutch core 12 .

[0120] Please see again Fig. 9 , Fig. 9 It is a schematic diagram of the three-dimensional structure of the first engaging member in an embodiment of the present application.

[0121] In some embodiments, the clutch mechanism 1 further includes a first elastic member 16, which is disposed between the annular wall portion 116 and the first bite member 13. When the first bite member 13 moves along the first direction P1 to deform the first elastic member 16, the first elastic member 16 applies an elastic force to the first bite member 13. When the lock is affected by knocking or vibration, causing the first bite member 13 to move along the first direction P1, the first bite member 13 moves to press against the first elastic member 16, causing the first elastic member 16 to be compressed. When the knocking or vibration effect disappears, the first elastic member 16 applies an elastic force to the first bite member 13, causing the first bite member 13 to reset.

[0122] In some embodiments, the first elastic member 16 may be a spring, one end of which is connected to the annular wall portion 116, and the other end is a free end, and when the first engaging member 13 moves to abut against the free end of the spring, the spring may be compressed if the first engaging member 13 continues to move. Of course, the free end of the spring may also be connected to the first engaging member 13, and in the natural state or stretched state of the spring, the first engaging member 13 is in a position where the first stop portion 131 and the second stop portion 132 abut against the first protruding portion 115a and the second protruding portion 115b, respectively.

[0123] In some other embodiments, the first elastic member 16 may also be a spring sheet, which has a first side and a second side opposite to each other along its thickness direction, the first limiting portion 114a is provided with a first bearing surface 114d, the second limiting portion 114b is provided with a second bearing surface 114e, the first side of the spring sheet abuts against the first bearing surface 114d and the second bearing surface 114e, and the second side faces the annular wall portion 116. When the first engaging member 13 moves along the first direction P1 to abut against the spring sheet, the first engaging member 13 bends the spring sheet to store elastic potential energy, and the spring sheet applies elastic force to the first engaging member 13 when it returns to its original state.

[0124] It can be understood that the thickness direction of the spring piece is the same as the first direction P1. In this way, the size of the clutch mechanism 1 in the first direction P1 can be reduced. At the same time, the use of the annular wall portion 116 and the two bearing surfaces to limit the spring piece can simplify the overall structure of the clutch mechanism 1, facilitate assembly, and reduce production costs.

[0125] Please also see Fig.10 , Fig.10 It is a schematic diagram of the three-dimensional structure of the first engaging member in an embodiment of the present application.

[0126] In some embodiments, when the first elastic member 16 is a spring sheet, the first engaging member 13 has a first end and a second end opposite to each other along the first direction P1, the first end is provided with an engaging portion 133, the engaging portion 133 is used to engage with the second engaging member 14, and the second end has an end face 134 facing the annular wall portion 116, and the end face 134 is recessed toward the first end. By making the end face 134 of the second end of the first engaging member 13 recessed toward the first end, bulges are formed on both sides of the second end of the first engaging member 13 along the second direction P2. When the first engaging member 13 moves along the first direction P1 and presses against the spring sheet, since the second side of the spring sheet faces and abuts against the annular wall portion 116, the bulges on both sides of the second end of the first engaging member 13 can drive the spring sheet to bend, so that the spring sheet stores elastic potential energy, and provides a restoring elastic force for the restoration of the first engaging member 13. At the same time, the recess at the second end of the first engaging member 13 can be nested with the annular wall portion 116 , which can reduce the size of the clutch mechanism 1 in the first direction P1 and help achieve a miniaturized design of the clutch mechanism 1 .

[0127] Please also see Fig.11 and Fig.12 , Fig.11 is a schematic diagram of the assembly of the first pressing plate in the embodiment of the present application, Fig.12 It is a schematic diagram of the structural explosion of the clutch mechanism with a first pressure plate in an embodiment of the present application.

[0128] In some embodiments, the handle connection base 11 is further provided with a first pressing plate 17, which is connected to the first limiting portion 114a and the second limiting portion 114b, and the first pressing plate 17 is arranged opposite to the first bottom wall 114. That is, the first bottom wall 114, the first limiting portion 114a, the second limiting portion 114b and the first pressing plate 17 form an active position 114c, and the first bottom wall 114, the first protruding portion 115a, the second protruding portion 115b and the first pressing plate 17 form the first opening 111a. By providing the first pressing plate 17, the first engaging member 13 and the first elastic member 16 can be restricted in the installation space 111.

[0129] Optionally, the first pressing plate 17 may be detachably connected to the first limiting portion 114a and the second limiting portion 114b by means of screw connection, plug connection, clamping connection, bonding or welding.

[0130] The structure of the clutch core will be introduced in detail below.

[0131] Please also see Fig.13 , Fig.13It is a schematic diagram of the internal structure and assembly of the clutch core disclosed in the embodiment of the present application.

[0132] In some embodiments, the clutch core 12 is arranged corresponding to the open side of the rotating seat 112, that is, when the clutch core 12 is sleeved on the outer periphery of the rotating seat 112, the clutch core 12 can roughly cover a portion of the opening of the rotating seat 112. Specifically, the clutch core 12 may include a sleeve portion 122, the sleeve portion 122 is connected to the slide groove portion 121, and the sleeve portion 122 is arranged around the outer periphery of a portion of the rotating seat 112. When the first bite member 13 and the second bite member 14 are separated from each other, the sleeve portion 122 can rotate relative to the rotating seat 112. When the first bite member 13 and the second bite member 14 are engaged with each other, the sleeve portion 122 can rotate synchronously with the rotating seat 112 driven by the rotating seat 112.

[0133] In some embodiments, the sleeve portion 122 has a second bottom wall portion 122a and a second side wall portion 122b. The second bottom wall portion 122a can be semicircular. The second side wall portion 122b is arranged along the arc edge of the second bottom wall portion 122a and is connected to the second bottom wall portion 122a. The second side wall portion 122b is not arranged at a position other than the arc edge of the second bottom wall portion 122a, so that the sleeve portion 122 forms a semicircular shell shape, and the rotating seat 112 is partially located in the semicircular shell.

[0134] Of course, the second bottom wall portion 122a may also be non-circular, and may be specifically configured according to actual conditions, which will not be described in detail herein. The sleeve portion 122 may also be transmission-connected to the lock core.

[0135] Optionally, the slide groove portion 121 can be arranged on the second side wall portion 122b, and the slide groove portion 121 can extend along the radial direction of the second bottom wall portion 122a. The slide groove portion 121 can be a protrusion protruding on the second side wall 122b, and the slide groove portion 121 also has a slide groove 121b extending along the first direction P1. The slide groove 121b is connected to the second opening 121a, and the second engaging member 14 is located in the slide groove 121b and can move along the first direction P1 in the slide groove 121b.

[0136] Please also see Fig.14 and Fig.15 , Fig.14 is a schematic diagram of the assembly of the second elastic member in the embodiment of the present application, Fig.15 It is a schematic diagram of the structural explosion of the clutch mechanism with a second elastic member in an embodiment of the present application.

[0137] In some embodiments, the clutch mechanism 1 further includes a second elastic member 18, the clutch core 12 is provided with a third limit portion 123 spaced apart from the second bite member 14, the second bite member 14 is provided with a fourth limit portion 141, the third limit portion 123 and the fourth limit portion 141 are spaced apart along the first direction P1, the second elastic member 18 is located between the third limit portion 123 and the fourth limit portion 141, one end of the second elastic member 18 abuts against the third limit portion 123, and the other end of the second elastic member 18 abuts against the fourth limit portion 141. The second elastic member 18 is used to provide a resetting elastic force to the second bite member 14 when the second bite member 14 moves toward the first bite member 13. In this way, when the user unlocks the lock, the second bite member 14 moves along the first direction P1 and compresses the second elastic member 18. When the user completes unlocking, the elastic force of the second elastic member 18 drives the second bite member 14 to reset, so that the lock can automatically complete the locking. Furthermore, when the impact on the lock makes the force of the second engaging member 14 on the second elastic member 18 smaller than the elastic force of the second elastic member 18 , the second elastic member 18 can also prevent the lock from being unlocked by vibration.

[0138] In some embodiments, the second elastic member 18 is a spring, which is sleeved on the outer periphery of the second bite member 14. At this time, the third limiter 123 can be an annular structure arranged around the outer periphery of the second bite member 14, or a plurality of structures arranged at intervals around the outer periphery of the second bite member 14, and the fourth limiter 141 can be an annular protrusion arranged around the outer periphery of the second bite member 14, or a plurality of protrusions arranged at intervals around the outer periphery of the second bite member 14, one end of the spring abuts against the third limiter 123, and the other end abuts against the fourth limiter 141.

[0139] In some embodiments, the third limiting portion 123 is symmetrically arranged on two opposite sides of the second bite member 14 along the second direction P2, and the fourth limiting portion 141 is also symmetrically arranged on two opposite sides of the second bite member 14 along the second direction P2. Two second elastic members 18 are provided, and the two second elastic members 18 are arranged at intervals along the second direction P2, and are respectively arranged corresponding to the two fourth limiting portions 141. By providing two third limiting portions 123, the fourth limiting portion 141, and the second elastic member 18, and the third limiting portion 123, the fourth limiting portion 141, and the second elastic member 18 are correspondingly and symmetrically arranged on two opposite sides of the second bite member 14 in the second direction P2, the second bite member 14 can be subjected to balanced force and move more smoothly.

[0140] In some embodiments, the first elastic member 16 and the second elastic member 18 can be set such that the stiffness coefficient of the first elastic member 16 is smaller than that of the second elastic member 18. In other words, the first elastic member 16 and the second elastic member 18 can be set such that, under the same impact, the first elastic member 16 is easier to deform than the second elastic member 18. In this way, when the lock is subjected to vibration or knocking, the first bite member 13 moves upward along the first direction P1, and because the first elastic member 16 is easier to deform, while the second elastic member 18 has a greater hardness, the first elastic member 16 is deformed under the action of the first bite member 13, so that the first bite member 13 moves further upward, while the second elastic member 18 is less deformed, and the second bite member 14 is difficult to overcome the elastic force of the second elastic member 18, and the upward movement is smaller, so that the distance between the first bite member 13 and the second bite member 14 is larger.

[0141] Please see again Fig.15 In some embodiments, the clutch mechanism 1 further includes a second pressure plate 19 , which is connected to the slide groove portion 121 . By providing the second pressure plate 19 , the second engaging member 14 and the second elastic member 18 can be restricted in the slide groove portion 121 .

[0142] Optionally, the second pressing plate 19 may be detachably connected to the slide groove portion 121 by means of screwing, plugging, clamping, bonding or welding.

[0143] See again Fig.15 In some embodiments, two installation spaces 111 are provided on the handle connection base 11, and two first openings 111a are formed on the second side wall portion 115. There are two first engaging members 13, and the two first engaging members 13 are provided in the two installation spaces in a one-to-one correspondence. In this way, when the clutch mechanism 1 is applied to doors and windows of different directions (left opening, right opening), the requirements of doors and windows of different directions can be met by simply rotating the second engaging member 14 to be able to cooperate with different first engaging members 13.

[0144] It can be understood that one of the first engaging member 13 and the second engaging member 14 is provided with a slot, and the other is provided with a latch. The engagement of the first engaging member 13 and the second engaging member 14 is achieved by inserting the latch into the slot. That is, the engaging portion 133 of the first engaging member 13 can be a slot or a latch. When the engaging portion 133 is a slot, the second engaging member 14 is provided with a latch that matches the slot, or the second engaging member 14 itself is a latch. When the engaging portion 133 is a latch, the second engaging member 14 is provided with a slot that matches the latch.

[0145] Please also see Fig.16 , Fig.16 It is a schematic diagram of the internal structure of a lock in an embodiment of the present application.
