Description
Technical Field
[0001] The utility model relates to the technical field of locks, and in particular to a handle clutch mechanism and a lock. Background Art
[0002] In some lock products with different functional bolts (such as oblique bolts, square bolts, etc.), in order to facilitate the user to operate the lock, the handle will be set to cooperate with the bolts with different functions, so that the handle can control the corresponding bolts through different operation methods to achieve the switch between different states of the lock. For example, when the handle is in forward motion, the handle will be linked with the oblique bolt to retract the oblique bolt into the lock to achieve the basic unlocking function of the lock, and when the handle is in reverse motion, the handle will be linked with the square bolt to extend the square bolt out of the lock to achieve the reverse locking function of the lock.

[0037] In addition, since the handle assembly only needs to be rotated in the same direction in different states of the lock, it also avoids the situation where the handle assembly needs to be rotated in different directions to operate the lock to switch between different states, which may cause interference with external environmental characteristics (such as door frames). This ensures that the lock can switch normally between different states while allowing the door body where the lock is located to open and close normally, meeting user needs and improving the user experience.

DETAILED DESCRIPTION
[0053] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0054] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0055] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0056] A lock refers to a device that performs a sealing function, which includes a lock, a key, and its accessories. In some lock products with lock tongues with different functions (such as an oblique tongue, a square tongue, etc.), in order to facilitate the user's operation of the lock, the handle will be set to cooperate with the lock tongues with different functions, so that the handle can control the corresponding lock tongue through different operating methods, thereby realizing the switching of the lock between different states.
[0057] For example, when the handle moves forward, the handle will work with the oblique tongue to retract the oblique tongue into the lock, thereby realizing the basic unlocking function of the lock. When the handle moves backward, the handle will work with the square tongue to extend the square tongue out of the lock, thereby realizing the reverse locking function of the lock.
[0058] For example, in a method in which the handle (door handle) can drive the inclined bolt to retract the lock by rotating in the positive direction to achieve the basic unlocking function of the lock, the user rotates the handle in the positive direction (usually clockwise, but it depends on the design and installation direction of the lock), and the rotation of the handle is transmitted through the transmission mechanism inside the lock (such as square rods, gears, transmission racks, etc.), so that the rotation of the handle can be converted into linear motion of the inclined bolt, and finally the inclined bolt slides along the corresponding lock hole of the lock and retracts, so that the locked state between the door leaf and the door frame is successfully released.
[0059] In the method in which the handle can drive the square tongue to extend out of the lock by reverse rotation, thereby realizing the anti-locking function of the lock, the user rotates the handle in the opposite direction (usually counterclockwise). Similar to the forward rotation process, the rotation of the handle is transmitted through the transmission mechanism inside the lock. In this process, the connection between the transmission mechanism and the square tongue is activated. As the handle continues to rotate, the transmission mechanism transmits the rotational force to the square tongue and drives the square tongue to extend out of the lock. The extension of the square tongue can create an interference relationship between the door leaf and the door frame, thereby preventing the door leaf from closing, or locking the door leaf to the door frame, that is, the anti-locking state.
[0060] From the background technology, it can be seen that although the above-mentioned method improves the structural compactness of the lock and reduces the number of components on the lock, the handle needs to be rotated in different directions to switch the lock state accordingly, and the operation method of switching the lock between different states is also relatively cumbersome. In addition, after the handle is rotated in different directions, the handle may interfere with components such as the door frame. For example, taking the method in which the handle is arranged along the vertical direction of the door leaf in the initial state, and when the handle is rotated in the forward direction to unlock, the handle rotates toward the door axis as an example, during the process of the handle rotating in the reverse direction, the handle will move toward the door edge (the side of the door leaf away from the door axis) and protrude from the door edge. In this state, it will affect the normal opening and closing of the door leaf, and ultimately reduce the user experience.
[0061] In view of this, the present embodiment provides a handle clutch mechanism, which provides a clutch mechanism-like structure on the handle assembly 10 to change the transmission relationship between the handle assembly 10 and different lock tongues when the clutch mechanism is in different position states, thereby solving a series of problems such as the poor convenience of lock operation and the possibility of interference between the handle and external features.
[0062] Please refer to the attached Figure 2-Figure 13 , the handle clutch mechanism comprises:
[0063] The handle assembly 10 is the part of the lock system that is directly operated by the user to open or close the lock. The handle assembly 10 can be made of, but is not limited to, materials such as metal or plastic, and its shape and structure can also be adjusted accordingly based on the design requirements of the lock product and user needs. This embodiment does not have any specific and strict restrictions on this.
[0064] In actual application scenarios, the handle assembly 10 will form a transmission coordination relationship with the internal components of the lock, so that when the user operates the handle assembly 10, the internal components of the lock are driven to move in conjunction, and ultimately the lock core is controlled to achieve the opening and closing of the lock.
[0065] In the present embodiment, a limiting through hole 11 is provided in the handle assembly 10, and the opposite ends of the limiting through hole 11 respectively correspond to and pass through the opposite ends of the handle assembly 10, and when the handle assembly 10 is in the application state of the lock, one end of the limiting through hole 11 is connected to one end of the handle assembly 10 that can be used by the user for operation, and the other end thereof is connected to the inside of the lock.
[0066] Exemplarily, taking the case where the handle assembly 10 is installed on the lock housing 50 in a manner that it can rotate relative to the lock housing 50 of the lock as an example, the center axis of the limiting through hole 11 is set to coincide with or nearly coincide with the rotation axis of the handle assembly 10. In this way, when the handle assembly 10 is rotated by the user, the limiting through hole 11 will not have a large radial displacement in the handle assembly 10, ensuring that the components assembled in the limiting through hole 11 and the internal parts of the lock maintain a relatively stable transmission matching relationship. It should be understood that the rotation axis formed by the handle assembly 10 on the lock housing 50 of the lock in this embodiment includes, but is not limited to, being set perpendicular to the panel 52 of the lock and parallel to the panel 52 of the lock.
[0067] Please refer to the attached Figure 1 It should be explained that the panel 52 of the lock mentioned above refers to the plate-like parts of the lock shell 50 of the lock, which are located on the outside and inside of the door leaf, respectively. It not only protects the lock core and the internal mechanical structure, but also has a certain decorative effect. Generally, the surface of the panel 52 of the lock is set to be parallel to the surface of the door leaf.
[0068] The transmission member 20 is a transmission member used to transmit the torque of the handle assembly 10 in a certain use state of the handle clutch mechanism. In the application scenario of the lock, the transmission member 20 is used to be movably mounted on the lock housing 50 of the lock. When the operating part 311 changes its corresponding position state, the matching relationship between the transmission member 20 and the handle assembly 10 and / or the operating assembly 30 will also change accordingly. In order to facilitate the understanding of the scheme, the matching relationship and transmission process between the transmission member 20 and the handle assembly 10 and / or the operating assembly 30 in different position states will be further explained in the subsequent implementation of the structure and function of the operating assembly 30.
[0069] The operating component 30 is movably arranged in the limiting through hole 11 along the extension direction of the limiting through hole 11. It can be understood from the above content that since the limiting through hole 11 passes through the opposite ends of the handle component 10, the opposite ends of the operating component 30 will also be respectively exposed to the outside of the opposite ends of the handle component 10 through the opposite ends of the limiting through hole 11, that is, one end of the operating component 30 will be exposed to the end of the handle component 10 that can be operated and controlled by the user through one end of the limiting through hole 11. In actual application scenarios, this end of the operating component 30 also generally provides the user with an operating position for operation and control, and the other end of the operating component 30 will be exposed to the inside of the lock shell 50 of the lock through the other end of the limiting through hole 11, so as to form a transmission matching relationship with the different mechanical structures of the handle component 10 inside the lock in actual application scenarios.
[0070] It should be understood that, in addition to being set as a straight through hole (set along the rotation axis 131 of the handle assembly 10) as mentioned above, the position-limiting through hole 11 in the handle assembly 10 can also be set as a different structural form. For example, the position-limiting through hole 11 in the handle assembly 10 can also be set as a structure of multiple sections connected in sequence, and any two adjacent sections of holes can be connected at an angle. It only needs to ensure that both ends of the position-limiting through hole 11 pass through the handle assembly 10 respectively, and when the operating assembly 30 is set in the position-limiting through hole 11, the operating assembly 30 can be controlled accordingly at the other end by the user's operation on one end.
[0071] Exemplarily, taking the implementation in which the above-mentioned limiting through hole 11 is arranged along the rotation axis of the handle assembly 10 as an example, the moving direction of the operating component 30 in the limiting through hole 11 is also parallel to the rotation axis of the handle assembly 10, and the opposite ends of the operating component 30 are respectively exposed to the outside of the lock and the inside of the lock (the lock shell 50) through the opposite ends of the limiting through hole 11, and when the user operates the end exposed to the outside of the lock, the end of the operating component 30 located inside the lock (the lock shell 50) can change the matching relationship between it and the handle assembly 10 and the transmission member 20, thereby achieving the purpose of switching the operation mode of the lock for different lock tongues.
[0072] To facilitate the understanding of the scheme, the present embodiment roughly defines the position state of the operating component 30 in the limiting through hole 11 as a transmission position and a release position. In actual application scenarios, the operating component 30 can be operated by the user (by pressing, pulling, etc.) to perform telescopic movement along the limiting through hole 11 relative to the handle component 10 between the transmission position and the release position.
[0073] When the operating assembly 30 is in the transmission position, the transmission member 20 is connected to the handle assembly 10 and the operating assembly 30 respectively, so that the handle assembly 10 can drive the operating assembly 30 through the transmission member 20 and make the operating assembly 30 and the handle assembly 10 rotate in opposite directions.
[0074] When the operating assembly 30 is in the released position, the transmission relationship between the transmission member 20 and the handle assembly 10 and / or the operating assembly 30 changes:
[0075] 1. The transmission member 20 and the handle assembly 10 are out of the transmission matching relationship (the transmission member 20 releases the handle assembly 10). In this way, when the user operates the handle assembly 10, the handle assembly 10 cannot drive the transmission member 20 to move, that is, the transmission member 20 will not drive the operating assembly 30 to perform a corresponding action;
[0076] Second, the transmission member 20 and the operating assembly 30 are disconnected from the transmission matching relationship (the transmission member 20 releases the operating assembly 30). In this way, when the user operates the handle assembly 10, although the handle assembly 10 and the transmission member 20 maintain the transmission matching relationship, the operating assembly 30 and the transmission member 20 are disconnected from the matching relationship. Therefore, the handle assembly 10 cannot be driven to move by the transmission member 20 during the operation of the handle assembly 10;
[0077] 3. The transmission member 20, the handle assembly 10 and the operating assembly 30 are all out of the transmission matching relationship.
[0078] When the operating assembly 30 is in the transmission position, the operating assembly 30 and the handle assembly 10 are fixed along the circumferential direction, so that the handle assembly 10 can drive the operating assembly 30 to rotate in the same direction as the handle assembly 10 .
[0079] In order to have a more comprehensive understanding of this implementation, the following is a further explanation and description of this solution by taking the actual application scenario of the handle clutch mechanism in a lock as an example:
[0080] In the embodiment where the lock also includes an inclined tongue and a square tongue, generally, the inclined tongue forms a transmission matching relationship with the handle assembly 10, and the user can operate and control (such as forward rotation) the handle assembly 10 to drive the inclined tongue to extend and retract into the lock housing 50 of the lock, thereby realizing the basic opening and closing of the lock. The square tongue forms a transmission matching relationship with the operating assembly 30, and the user can operate and control (such as reverse rotation) the operating assembly 30 through the handle assembly 10, so that the operating assembly 30 drives the square tongue to extend out of the lock housing 50 of the lock, and then the operating assembly 30 can be operated and controlled (such as forward rotation in the opposite direction of reverse rotation) through the handle assembly 10, so that the operating assembly 30 drives the square tongue to retract from the state of extending out of the lock housing 50 into the lock housing 50.
[0081] It should be understood that the inclined bolt is a common type of bolt in the lock, which is responsible for retracting and retracting in the normal closing and opening operations. Generally speaking, one side of the inclined bolt is a plane, and the other opposite side is an inclined surface. According to the opening and closing direction of the door leaf, the plane of the inclined bolt is generally located on the side of the door leaf opening direction, so that the inclined bolt can cooperate with the door frame lock hole through its plane to lock the lock together with the door leaf in a closed state, and through the guiding cooperation between the inclined bolt and the door frame, the inclined bolt can be retracted into the lock under the action of the door frame. The opposite sides of the square tongue are both planes, that is, when the door leaf is in a closed state, when the square tongue extends out of the lock, the square tongue can restrict the lock together with the door leaf from opening, and when the door leaf is in an open state, when the square tongue extends out of the lock, the square tongue will interfere with the door frame, making it impossible for the door leaf to be closed.
[0082] Through the above arrangement, when the operating component 30 is in the release position, the handle assembly 10 can normally drive the inclined tongue by forward rotation. Since the operating component 30 rotates in the same direction as the handle assembly 10, the square tongue will not be stimulated by the operating component 30 at this time, so that the lock can drive the inclined tongue to retract into the lock and keep the square tongue in the state of being retracted into the lock, thereby realizing normal opening of the lock; and when the operating component 30 is in the transmission position, since the operating component 30 forms a transmission relationship with the handle assembly 10 through the transmission assembly, the handle assembly 10 can still drive the operating component 30 to rotate in the opposite direction through the transmission member 20 by forward rotation. During this process, although the inclined tongue is still driven by the handle assembly 10 and moves in the direction of being retracted into the lock, since the operating component 30 is driven by the transmission assembly and rotates in the opposite direction, the square tongue is also stimulated and moves in the direction of extending out of the lock, thereby achieving the purpose of realizing the locking function of the lock.
[0083] That is to say, no matter the user wishes to operate only the oblique tongue to open the lock, or wishes to operate the square tongue to lock the lock, he can achieve different effects by operating the handle assembly 10 to rotate in the same direction (such as the forward direction described above). The process only needs to control the operating assembly 30 to change its position state. The operating logic and method are simpler, making the lock easier to operate and reducing the learning cost required to operate the lock. At the same time, since the handle assembly 10 only needs to rotate in the same direction in different states of the lock, in the actual application of the lock, the direction of the handle assembly 10 to operate the lock to open and the direction of the lock to lock can also be set to rotate in the direction of the door axis, thereby avoiding the situation where the handle assembly 10 needs to rotate in different directions to operate the lock to switch between different states, which causes interference with external environmental characteristics (such as door frames). While ensuring that the lock can switch normally between different states, the door body where the lock is located can also be opened and closed normally, meeting user needs and improving the user experience.
[0084] Of course, the operation mode of the handle clutch mechanism on the square tongue in the application of the lock is not limited to this. Since the operating component 30 can rotate in the same direction as the handle component 10 in the transmission position state, the user can also drive the operating component 30 to stimulate the square tongue by operating the handle component 10 to rotate in the opposite direction when the operating component 30 is in the transmission position, so that the handle clutch mechanism can be driven to lock in the application of the lock in the existing lock operation mode, so as to provide more operation modes for users to choose and meet the usage requirements of different users.
[0085] It should be noted that in order to enable the transmission member 20 to drive the operating assembly 30 to rotate in the opposite direction through the handle assembly 10 when the operating assembly 30 is in the transmission position, the transmission member 20 may apply a torque in the opposite direction of the handle assembly 10 to the operating assembly 30 in the following manners, but not limited to:
[0086] In addition to setting a lever between component 1 and component 2, there are many other ways to make them rotate in opposite directions. The following are some common methods:
[0087] 1. Lever mechanism transmission, the transmission member 20 is rotatably connected to the lock of the lock housing 50 to determine the fulcrum of the lever mechanism, and its opposite ends are respectively connected to the operating assembly 30 by connecting the handle assembly 10. When the handle assembly 10 drives the transmission member 20 to rotate in the positive direction, the end of the transmission member 20 connected to the handle assembly 10 will move with the handle assembly 10 around its fulcrum, and the end of the transmission member 20 connected to the operating assembly 30 will rotate in the opposite direction around its fulcrum, thereby applying a torque opposite to the movement direction of the handle assembly 10 to the operating assembly 30, thereby driving the operating assembly 30 to rotate in the opposite direction to the handle assembly 10;
[0088] 2. Gear transmission. The transmission member 20 can be configured as at least three gears meshing with each other, one of which is rotatably mounted on the lock housing 50, and the other two gears are rotatably mounted on the handle assembly 10 and the operating assembly 30, respectively. When one of the gears moves with the handle assembly 10, it drives the gear rotatably mounted on the lock housing 50 to rotate, and allows the gear to drive the gear on the operating assembly 30 to rotate in the opposite direction, thereby finally driving the operating assembly 30 to rotate in the opposite direction to the handle assembly 10.
[0089] Of course, since the rotation center of the gear disposed on the lock housing 50 is staggered from the rotation center of the handle assembly 10 and the operating assembly 30, in order to ensure that the gears can maintain a meshing state during the relative movement of the handle assembly 10 and the operating assembly 30, the handle assembly 10 and the operating assembly 30 may further be provided with a plurality of gears arranged around the gear disposed on the lock housing 50 at intervals, so that the transmission stability of the handle assembly 10 and the operating assembly 30 is ensured by the plurality of gears being sequentially meshed with the gear disposed on the lock housing 50;
[0090] 3. Belt or chain transmission, which is similar to the above-mentioned gear transmission principle, uses pulleys or sprockets to be respectively arranged on the operating assembly 30, the lock housing 50 and the operating assembly 30, and allows the pulleys or sprockets to be driven by corresponding belts and chains, so that the handle assembly 10 can drive the operating assembly 30 to rotate in the opposite direction through the transmission member 20 realized by the above-mentioned principle;
[0091] 4. Friction wheel transmission. Its transmission structure and principle are similar to the above-mentioned gear transmission method, and this embodiment will not be described in detail.
[0092] 5. Reverse clutch transmission: the transmission member 20 is set as a reverse clutch, so that the transmission member 20 can transmit the torque applied by the handle assembly 10 to the operating assembly 30 in the opposite direction.
[0093] Please continue to refer to the attached Figure 4-Figure 5 In order to facilitate the description of this embodiment, this embodiment sets one end of the limiting through hole 11 as the operating end 111, and the other end of the limiting through hole 11 is set as the transmission end 112. Further explanation is given in combination with the above embodiment. In actual application scenarios, the limiting through hole 11 is connected to the external environment of the lock through the operating end 111, so that the operating component 30 is exposed to the handle assembly 10 for user operation. The limiting through hole 11 is connected to the internal environment of the lock through the transmission end 112, so that the operating component 30 can be exposed inside the lock through the transmission end 112 and form a transmission matching relationship with the handle assembly 10 or the transmission member 20 to achieve switching between different position states.
[0094] Correspondingly, the operating component 30 is provided with an operating part 311 exposed through the operating end 111, and a clutch part 321 that can be extended from the transmission end 112. The operating part 311 and the clutch part 321 are relatively fixed along the axial direction of the limiting through hole 11 to maintain the matching relationship between the two parts in their movement directions, so that the user can drive the clutch part 321 to move along the direction of the limiting through hole 11 through the operating part 311, which is specifically used to control the clutch part 321 to extend from the transmission end 112 to operate and switch the position state of the operating component 30.
[0095] According to the above embodiment, it can be understood that the operating portion 311 of the operating component 30 provides a corresponding operating position for the user, and the operating component 30 forms a matching relationship or a disengagement relationship with the transmission member 20 through its clutch portion 321. According to the movement mode of the operating component 30 in the limit through hole 11, when the operating component 30 is in the transmission position, the operating portion 311 moves in the direction of retracting into the operating end 111 under the operation of the user, and drives the clutch portion 321 to move in the direction of extending out of the transmission end 112, so that the clutch portion 321 and the transmission member 20 can form a matching relationship, that is, the operating component 30 is connected to the transmission member 20 through the clutch portion 321. When the operating component 30 is in the released position, the operating part 311 can move in the direction of extending out of the operating end 111 under the drive of the user or the internal mechanical structure of the lock, and at least part of the operating part 311 extends out of the operating end 111 to provide an operable position for the user. The clutch part 321 moves in the direction of retracting into the transmission end 112 along with the operating part 311 and disengages from the transmission member 20 and is circumferentially fixed to the handle assembly 10.
[0096] By defining the operating end 111 and the transmission end 112 of the limit through hole 11, and defining the operating part 311 and the clutch part 321 of the operating component 30 through the above-mentioned implementation method, the technicians in this field can more clearly understand the relative position relationship between the operating component 30 and the limit through hole 11 and the transmission member 20 in different position states, so as to at least ensure that the operating component 30 can provide an operable position for the user through the operating part 311 in the release position, and how to maintain a good matching relationship with the transmission member 20 in the transmission position, so as to make the overall operation logic of the handle clutch mechanism clearer, reduce the research and development cost of the mechanism, and correspondingly reduce the difficulty of subsequent production and assembly. In addition, through the definition and description of the corresponding features, the subsequent technical solutions of this implementation method can also be easier to understand.
[0097] Please refer to the attached Figure 2-Figure 13 Taking the lever mechanism transmission method mentioned above as an example, in this embodiment, the transmission member 20 is set as a lever, and the lever can be adaptively adjusted according to the design requirements of the handle clutch mechanism and the structure of the handle assembly 10 and the operating assembly 30 to ensure that it can form a corresponding matching relationship with the handle assembly 10 and the operating assembly 30 when the operating assembly 30 is in different position states, thereby ensuring that the handle clutch mechanism can provide the corresponding function normally.
[0098] Specifically, it can be preliminarily understood from the above content that in actual application scenarios, the lever needs to be rotatably mounted on the lock housing 50 of the lock to ensure the fulcrum of the lever mechanism, and the opposite ends of the lever are respectively provided with a toggle portion 21 and a drive portion 22, and the lever can be movably connected to the handle assembly 10 through the toggle portion 21, and can be movably connected to the operating assembly 30 through the drive portion 22. That is, when the operating assembly 30 is in the transmission position, the toggle portion 21 and the drive portion 22 of the lever are respectively connected to the handle assembly 10 and / or the operating assembly 30 to transfer the torque therebetween. When the operating assembly 30 is in the release position, the toggle portion 21 and the drive portion 22 of the lever are respectively separated from the handle assembly 10 and / or the operating assembly 30, thereby avoiding the situation where the handle assembly 10 transfers its torque to the operating assembly 30 through the lever.
[0099] According to the lever principle, the fulcrum of the lever mechanism needs to be located between two components that need to transmit opposite torques. Therefore, this embodiment sets the fulcrum between the toggle portion 21 and the driving portion 22. Specifically, the toggle lever is further provided with a rotating portion 23 rotatably mounted on the lock housing 50 of the lock through the toggle portion 21 and the driving portion 22, so as to define the fulcrum of the entire lever mechanism through the rotational connection relationship between the rotating portion 23 and the lock housing 50 of the lock.
[0100] It should be explained that the lever uses its rotating portion 23 as a fulcrum and the forces acting on its toggle portion 21 and the driving portion 22 to establish a corresponding transmission relationship between the handle assembly 10 and the operating assembly 30. In order to adjust the spacing between the rotating portion 23 and the toggle portion 21 and the driving portion 22 respectively according to the angle of rotation required for the handle assembly 10 to drive the oblique tongue and the angle of rotation required for the operating assembly 30 to drive the square tongue, thereby ensuring that the transmission member 20 can stably realize the transmission between the two, in some embodiments, the torque applied by the handle assembly 10 to it can also be amplified, thereby saving the force and rotation distance required by the user when operating the square tongue through the operating assembly 30. In order to enable the lever to drive the operating assembly 30 to rotate in the direction opposite to the rotation direction of the handle assembly 10, when the operating assembly 30 is in the transmission position, the undulating section and the driving end of the lever must be connected to the handle assembly 10 and the operating assembly 30, and the connection method needs to be able to generate opposite torques. However, this does not mean that the two ends of the lever must be strictly connected to the same semicircle of the handle assembly 10 and the operating assembly 30, but the connection method must be able to ensure that when one end of the lever applies a forward rotation force, the other end can apply a reverse rotation force.
[0101] Furthermore, the design of the lever can be varied as long as it can meet the above torque requirements. For example, one end of the lever can be connected to one semicircle of the handle assembly 10, and the other end can be connected to the other semicircle of the operating assembly 30 through a transmission mechanism (such as a gear, chain or belt) to achieve reverse rotation.
[0102] The operation assembly 30 is driven by the clutch mechanism principle to realize the formation and release of the above-mentioned lever mechanism. In addition to being able to realize the same-direction rotation and reverse rotation of the operation assembly 30 and the handle assembly 10, these two sets of simple machines can also realize the transmission mode of the two in different states in the most direct way. There is no need to add additional mechanical structure between the handle assembly 10 and the operation assembly 30, thereby simplifying the structure of the handle clutch mechanism. In addition, through the direct transmission of the lever, the energy loss in the transmission process is also reduced, and the transmission efficiency between the handle assembly 10 and the operation assembly 30 is improved. The compact lever mechanism design helps to reduce space occupation, making the entire transmission system more compact and efficient.
[0103] When the user uses the lock, he only needs to simply rotate the handle assembly 10, and rotate the handle assembly 10 in the same direction while controlling the operating assembly 30. Thanks to the simple mechanical structure of the clutch mechanism and the lever mechanism, the control logic is simplified and the complexity of the transmission structure is reduced.
[0104] It is also worth mentioning that, since the operating component 30 maintains a circumferentially fixed relationship with the handle component 10 in the released position, the relative relationship between the operating component 30 and the handle component 10 is also maintained when they are not linked by the transmission member 20 (shift rod). That is, the position of the handle component 10 for connection with the shift rod and the position of the operating component 30 for connection with the shift rod remain unchanged. In this way, when the operating component 30 is switched from the released position to the transmission position, the handle component 10, the operating component 30 and the shift rod can cooperate accurately to enable subsequent operations to be smoothly implemented.
[0105] Based on the above-mentioned embodiment in which the transmission member 20 is a lever, Figure 6-Figure 13 As shown, the clutch portion 321 mentioned above is protruding from one end of the operating component 30 for connecting with the transmission member 20, and the clutch portion 321 is eccentrically arranged with respect to the rotation center of the operating component 30. Thus, when the clutch portion 321 is connected to the transmission member 20, the clutch portion 321 can exert a force on the operating component 30 to rotate around its rotation axis under the action of the transmission member 20.
[0106] Correspondingly, the driving part 22 is configured as a shifting groove opened at the end of the shifting rod (driving part 22), the shifting groove is an open structure and the notch is located on the side of the shifting groove away from the driving part 22, so that the operating component 30 can cooperate and separate with the shifting groove through the clutch part 321 during the switching process between the transmission position and the release position.
[0107] It should be noted that, since the rotation center of the lever is eccentrically arranged with respect to the rotation center of the handle assembly 10 and the operating assembly 30, when the handle assembly 10 is driven by the lever to rotate in the opposite direction, the clutch portion 321 on the operating assembly 30 will move in a direction gradually approaching or away from the rotating portion 23 of the lever. Therefore, in order to avoid the clutch portion 321 being stuck in the lever groove, the lever groove is arranged to be a structure extending along the length direction of the lever, so that the clutch portion 321 can move relative to the lever along the direction in which the lever groove is opened during the above process, and it is also ensured that the lever groove can apply a torque in the corresponding direction to the operating assembly 30 by pressing the clutch portion 321 through its groove wall.
[0108] It should be noted that when the operating component 30 is switched between the transmission position and the release position, the clutch part 321 is not engaged with or separated from the shift groove through the above-mentioned open notch of the shift groove, but is inserted into or disengaged from the shift groove from an opening on one side of the shift groove by moving in a direction parallel to the rotation axis of the shift lever. The main purpose of forming the above-mentioned notch is to make one end of the shift groove an open structure so that the groove walls on both sides of the shift groove have a certain degree of freedom (through material plastic deformation, etc.), thereby reducing the interference between the groove walls on both sides of the shift groove and the clutch part 321, resulting in jamming.
[0109] Please continue to refer to the attached Figure 6-Figure 13 One end of the handle assembly 10 for connecting with the transmission member 20 is provided with a rotating shaft 131, and the rotating shaft 131 and the limiting through hole 11 are also eccentrically arranged.
[0110] Correspondingly, the toggle portion 21 is configured as an axial hole opened at the end of the toggle rod, and the axial hole is rotatably inserted and matched with the rotating shaft 131. In this example, the handle assembly 10 is configured so that the operating assembly 30 is connected to the transmission member 20 in both the transmission position and the release position, which can also reduce the difficulty of operating the handle clutch mechanism. The handle assembly 10 will not produce relative displacement with the lock housing 50 of the lock in the axial direction, ensuring that the user only needs to operate the operating assembly 30 when driving different lock tongues to extend and retract, thereby improving the stability of the handle assembly 10 on the lock housing 50. For this reason, in this embodiment, the handle assembly 10 is configured to be rotatably matched with the transmission member 20 through the axial hole, so that the handle assembly 10 and the toggle rod maintain a stable transmission relationship.
[0111] In the normal state of the handle assembly 10, the shaft 131, the rotating portion 23 of the lever, the clutch portion 321, and the rotation centers of the handle assembly 10 and the operating assembly 30 are all on the same straight line. In this way, the lever is also a straight rod body, so that when it is connected to the clutch portion 321 and the shaft 131 respectively through the toggle portion 21 and the driving portion 22, the lever can stably transmit the torque between the handle assembly 10 and the operating assembly 30, and when the spacing between the rotating portion 23 and the clutch portion 321 and the shaft 131 is equal, when the handle assembly 10 rotates forward by a preset angle, the operating assembly 30 can also rotate in the opposite direction by a corresponding angle. Regardless of whether the user operates the oblique tongue to unlock or the square tongue to unlock through the handle assembly 10, the rotation angle of the rotating handle assembly 10 is consistent, so as to improve the consistency of user operations in the two position states and enhance the user experience. Of course, when the user wishes to operate the square tongue when the operating assembly 30 is in the released position, the user reversely rotates the handle assembly 10 from the normal state to drive the operating assembly 30 to reverse the rotation angle required to operate the square tongue, which is consistent with the rotation angle required for the handle assembly 10 to rotate forward from the normal state to operate the inclined tongue, which is also helpful in reducing the difficulty of operating the lock.
[0112] Of course, in other embodiments, when the handle assembly 10 is in a normal state, the rotation centers of the rotating shaft 131, the rotating portion 23 of the lever, the clutch portion 321, and the handle assembly 10 and the operating assembly 30 may also be arranged to be not on the same straight line. In this case, the lever structure needs to be adaptively adjusted according to the connection line between the above-mentioned features to ensure that the lever shifting portion 21 and the driving portion 22 can respectively correspond to the connection between the clutch portion 321 and the rotating shaft 131.
[0113] In this example, the clutch part 321 and the rotating shaft 131 can both be set as a frustum structure, so that the rotating shaft 131 and the shaft hole, as well as the clutch part 321 and the shifting groove can maintain smoothness during relative rotation, reducing the jamming during the operation of the handle clutch mechanism and improving the user experience.
[0114] It needs to be explained that the normal state of the handle assembly 10 refers to a state in which the handle is not affected by external force. In a specific application scenario and the handle assembly 10 is in the normal state, the oblique tongue controlled by the handle assembly 10 is in a state of extending out of the lock shell 50 of the lock, and the square tongue indirectly controlled by the handle assembly 10 is also in a state of retracting into the lock shell 50 of the lock, that is, in this state, the lock can be normally closed to the door frame along with the door leaf.
[0115] According to the technical solution described in any of the above embodiments, in order to allow the operating assembly 30 to form a circumferentially fixed matching relationship with the handle assembly 10 in the state of the release position, so that the handle assembly 10 can drive the operating assembly 30 to rotate in the same direction as it, such as Figure 6-Figure 13 As shown, the operating assembly 30 and the handle assembly 10 are respectively provided with a first stop portion 322 and a second stop portion 132 with structural matching. The first stop portion 322 and the second stop portion 132 can move away from or approach each other along the axial direction of the limiting through hole 11 (i.e., the direction of movement between the release position and the transmission position of the operating assembly 30).
[0116] As further explanation based on the above structure, when the operating component 30 is in the transmission position, the first stop portion 322 and the second stop portion 132 are axially separated and disengaged from each other, so that the operating component 30 can rotate relative to the handle component 10, and on the basis that both the operating component 30 and the handle component 10 are connected to the transmission member 20, the handle component 10 can smoothly apply a torque in the opposite direction of its rotation to the operating component 30 through the transmission member 20; when the operating component 30 is in the release position, the first stop portion 322 and the second stop portion 132 are axially close to each other, and at this time, the operating component 30 and the transmission member 20 also correspondingly disengage from the mating relationship, so that the handle component 10 and the handle component 10 are circumferentially fixed.
[0117] In the embodiment in which the operating assembly 30 is in the released state and the operating assembly 30 and the transmission member 20 are out of the matching relationship, it can be understood from the above content that the second anti-rotation portion 132 located on the handle assembly 10 and the portion of the transmission member 20 used to match the operating assembly 30 (driving portion 22) are respectively arranged on opposite sides of the movement direction of the operating assembly 30. In this way, when the operating assembly 30 moves in the first direction (such as in the direction of extending the transmission end 112 of the limit through hole 11), the first anti-rotation portion 322 can move in the direction away from the second anti-rotation portion 132 and disengage from the second anti-rotation portion 132, and the clutch portion 321 can move in the direction close to the driving portion 22 and achieve matching with the transmission member 20. While when the operating component 30 moves in the second direction (such as in the direction of retracting the transmission end 112 of the limit through hole 11), the first stop portion 322 can move in the direction close to the second stop portion 132 and form a stop fit with the second stop portion 132, and the clutch portion 321 can move in the direction away from the driving portion 22 and disengage from the transmission member 20, ensuring that the operating component 30 can respectively form a fit with the handle assembly 10 or the transmission member 20 through different parts in the two position states, while also avoiding interference with parts that do not need to be linked in the corresponding position states, thereby affecting the operation of the lock.
[0118] Exemplarily, the first anti-rotation part 322 and the second anti-rotation part 132 can be specifically configured as a protrusion and a groove with matching structures. The protrusion and the groove should be configured to deviate from the rotation center of the handle assembly 10 and the operating assembly 30, so as to constrain the relative rotation of the handle assembly 10 and the operating assembly 30 when the protrusion and the groove are matched. In addition to realizing the anti-rotation of the two by matching the protrusion and the groove, a variety of structures can be used between the first anti-rotation part 322 and the second anti-rotation part 132 to constrain the relative rotation relationship between the handle assembly 10 and the operating assembly 30. For example, they can also be constrained by a buckle structure, through elastic buckles and slots that can match each other, so that the relative rotation of the handle assembly 10 and the operating assembly 30 is constrained when the two are in a mutually engaged state, and the two can be disengaged under a certain external force to unlock the circumferential constraint of the handle assembly 10 and the operating assembly 30.
[0119] Please refer to the attached Figure 6-Figure 13 An elastic reset member 40 is also provided between the operating assembly 30 and the handle assembly 10. The elastic reset member 40 acts on the operating assembly 30 and the handle assembly 10 respectively, and continuously applies an elastic force from the transmission position to the release position to the operating assembly 30, so that the operating assembly 30 has a tendency to move from the transmission position to the release position.
[0120] Such a configuration allows the operating assembly 30 to remain in the release position when it is not acted upon by other external forces, so that the user does not need to operate the operating assembly 30 when opening and closing the lock (the oblique tongue) in normal operation, thereby facilitating the user to quickly open and close the door and improving the user's operating convenience. When the user needs to unlock the lock (the square tongue) by operating the operating assembly 30, the user only needs to apply a force sufficient to overcome the elastic force of the elastic reset member 40 to the operating assembly 30, so that the operating assembly 30 can be moved from the release position to the transmission position, so that the subsequent rotation of the handle assembly 10 can drive the operating assembly 30 to move through the transmission member 20, and after performing the corresponding operation, the user releases the operating assembly 30, so that the elastic reset member 40 can drive the operating assembly 30 to reset from the transmission position to the release position, so as to facilitate the next lock opening operation.
[0121] It should be understood that in order to allow the operating component 30 to be maintained in the release position by the elastic return member 40 when not acted upon by other external forces, and to ensure that the operating component 30 can be stably in the transmission position under the operation of the user, an axial limiting structure that can limit the axial relative movement of the two should also be provided between the handle assembly 10 and the operating component 30, so as to ensure that the operating component 30 can only move axially relative to the handle assembly 10 between the release position and the transmission position.
[0122] Based on any of the above implementations, please refer to the attached Figure 6-Figure 13, as a specific structural form of the handle clutch mechanism, is as follows:
[0123] The handle assembly 10 includes a handle component 12 and a handle turntable 13. The handle component 12 is a component of the handle assembly 10 that can be operated by the user. In the specific application scenario of the handle clutch mechanism, most of the structure of the handle component 12 is arranged outside the lock shell 50 of the lock, and the remaining part of the handle component 12 is inserted into the lock shell 50 through the opening opened on the lock shell 50 of the lock. The handle turntable 13 is used to be rotatably arranged on the lock shell 50 of the lock (specifically located in the lock shell 50) and to cooperate with the square steel shaft of the lock. The handle component 12 is installed on the handle turntable 13, and the part of the handle component 12 connected to the handle turntable 13 is coaxially connected to the handle turntable 13, so that the handle component 12 can drive the handle turntable 13 to rotate under external force operation, and the limit through hole 11 passes through the handle component 12 and the handle turntable 13 in sequence, so as to provide the operation component 30 with connection and cooperation.
[0124] The operating assembly 30 includes a button 31 and a free turntable 32. The button 31 is arranged in the handle component 12 (in the corresponding limiting through hole 11). When the operating assembly 30 is in the release position, the button 31 at least partially extends out of the limiting through hole 11 (the operating end 111) to provide an operating position (the operating part 311 mentioned above) for the user to operate the operating assembly 30. The free turntable 32 is axially fixed to the button 31 and arranged in the handle turntable 13 (in the corresponding limiting through hole 11). The free turntable 32 is used to cooperate with the square steel shaft transmission. In the transmission position, the free turntable 32 is connected to the square steel shaft, so that the square steel shaft is driven to rotate coaxially with the free turntable 32 under the drive of the handle turntable 13; and in the release position, the free turntable 32 is separated from the square steel shaft, and the square steel shaft is connected to the handle turntable 13, so that the square steel shaft can rotate with the handle turntable 13.
[0125] According to the above, when the operating assembly 30 is in the transmission position, the free turntable 32 and the handle turntable 13 are connected to the transmission member 20 and can rotate relatively.
[0126] When the operating assembly 30 is in the released position, the free turntable 32 is separated from the transmission member 20 and is circumferentially fixed to the handle turntable 13 .
[0127] In the embodiment where the two opposite ends of the above-mentioned limiting through hole 11 are respectively set as the operating end 111 and the transmission end 112, the end of the limiting through hole 11 located in the handle component 12 away from the handle rotating disk 13 is the operating end 111, and the end of the limiting through hole 11 located in the handle rotating disk 13 away from the handle component 12 is the transmission end 112. Correspondingly, the part of the button 31 provided in the handle component 12 exposed outside the handle component 12 through the limiting through hole 11 forms the operating part 311, and the clutch part 321 is provided on the free rotating disk 32.
[0128] The handle assembly 10 and the operating assembly 30 in this embodiment can effectively reduce the difficulty of processing and assembling the handle assembly 10 and the operating assembly 30 through modular design, and it is worth mentioning that the handle component 12, the handle turntable 13, the button 31 and the free turntable 32 can also be further designed in a modular way to further reduce the difficulty of processing and assembling each component.
[0129] Based on the above embodiment, as a further solution, a connecting rod 33 is further provided between the button 31 and the free rotating disk 32, and the button 31 and the free rotating disk 32 are axially fixed by the connecting rod 33, wherein the connecting rod 33 and the free rotating disk 32 can be matched in the following manner:
[0130] 1. The connecting rod 33 is connected to the limiting through hole 11, and the handle component 12 can drive the connecting rod 33 to move around its rotation axis. One end of the connecting rod 33 is directly or indirectly rotatably connected to the free rotating disk 32;
[0131] 2. The connecting rod 33 is rotatably connected to the limiting through hole 11 and is coaxially connected to the free rotating disk 32.
[0132] This embodiment takes the embodiment in which the free turntable 32 can move (rotate) relative to the connecting rod 33 (the above-mentioned embodiment 1) as an example, the connecting rod 33 and the free turntable 32 are connected by a connecting shaft 34, one end of the connecting rod 33 is connected to the connecting shaft 34 by a relatively common matching method in the mechanical field such as snapping and clamping, and is circumferentially fixed to the connecting shaft 34, and the connecting shaft 34 is rotatably connected to the free turntable 32. In addition, in order to ensure that the axial force between the button 31 and the free turntable 32 can be transmitted through the connecting rod 33 and the connecting shaft 34, the connecting shaft 34 and the free turntable 32 should be set to an axially fixed matching form.
[0133] In addition, an elastic reset member 40 is provided between the button 31 and the handle component 12 . The elastic reset member 40 can be provided as a spring, and acts on the handle component 12 and the button 31 by being sleeved on the connecting rod 33 .
[0134] In one embodiment, a limit countersunk hole is provided at a position of the handle component 12 near the button 31 , and the connecting rod is extended from the limit countersunk hole when it is connected to the handle component 12 to allow the elastic reset member 40 to be mounted thereon.
[0135] In addition, in the embodiment in which the connecting rod 33 and the limiting hole of the handle part 12 are fixed to the handle part 12 in the circumferential direction, in order to ensure the stability of the torque transmission between the button 31 and the free turntable 32, the connecting rod 33 is set to more than two, and is arranged around the rotation axis of the handle part 12 in an equidistant manner. For example, in the case of two connecting rods 33 in this embodiment, the two connecting rods 33 are placed on opposite sides of the rotation axis of the handle part 12, and one end of the two connecting rods 33 acts on the opposite sides of the button 31 respectively, and the other ends of the two connecting rods 33 are fixed to the opposite sides of the connecting shaft 34 respectively, and the two connecting rods 33 are provided with elastic reset members 40, so that the elastic force of the elastic reset member 40 acting on the button 31 is also more stable. In this way, the portion of the limiting through hole 11 located in the handle part 12 for the connecting rod 33 to pass through can be correspondingly set to two or more, which is conducive to improving the structural strength of the handle part 12.
[0136] In the embodiment where the operating assembly 30 and the handle assembly 10 are respectively provided with the first stop portion 322 and the second stop portion 132 , the first stop portion 322 and the second stop portion 132 are respectively provided as a limiting protrusion located on the handle turntable 13 and a limiting groove located on the free turntable 32 .
[0137] Furthermore, in order to further improve the stability between the free turntable 32 and the handle turntable 13 when the operating assembly 30 is in the released position, a positioning groove 133 whose structure is adapted to the free turntable 32 is further provided on the surface of the handle turntable 13 on one side close to the transmission member 20, so that the free turntable 32 can be at least partially accommodated in the positioning groove 133, and the free turntable 32 and the handle turntable 13 can be stopped by the cooperation of the first stop portion 322 and the second stop portion 132. That is to say, the first stop portion 322 and the second stop portion 132 can be respectively arranged on the portion of the free turntable 32 accommodated in the positioning groove 133 and the groove wall of the positioning groove 133.
[0138] Please refer to the attached Figure 1-Figure 3The present embodiment also provides a lock, which, on the basis of adopting the handle clutch mechanism described in any of the above embodiments, also includes a lock shell 50, which defines a hollow installation cavity 51 inside, and the handle clutch mechanism is partially arranged outside the lock shell 50, and part of the handle component 12 and part of the button 31 are exposed outside the lock shell 50 for user operation, and the other part of the handle clutch mechanism is arranged in the installation cavity 51, and the handle dial 13, the free dial 32 and the transmission member 20 are arranged in the installation cavity 51, so that the handle clutch mechanism can realize the switching of the position state and control the corresponding lock tongue through the handle dial 13 and the free dial 32.
[0139] To sum up, the lock adopts the above-mentioned handle clutch mechanism, so that the user can change the operating state of the lock by simply operating the operating component 30 during the operation of the lock, so that the lock can be controlled by rotating the handle component 10 in the same direction regardless of whether it is controlling the oblique tongue or the square tongue, which greatly reduces the user's operating difficulty and avoids the situation where the handle component 10 needs to be rotated in different directions to control different tongues, causing the handle component 10 to interfere with external features such as the door frame, so that the lock can adapt to different usage scenarios.
