Description

Technical Field

[0001] This invention relates to the field of lock technology, specifically to an electromechanical separation lock body and lock. Background Technology

[0002] To achieve automated opening and closing of the lock body and remote intelligent control, current electronic locks typically incorporate a motor assembly. Specifically, the motor's output gear meshes with the main bolt transmission assembly, thereby driving the bolt to automatically lock and unlock, replacing the traditional manual mechanical unlocking method and improving the ease of use and intelligent security level of the lock.

[0003] However, since the motor output gear and the main locking bolt transmission assembly always maintain rigid meshing, when the motor malfunctions and jams or operates abnormally, the main locking bolt transmission assembly is prone to locking, causing the mechanical emergency unlocking to fail to operate normally. This poses safety risks such as users being trapped indoors or emergency unlocking failing, reducing the safety and emergency reliability of the electronic lock. Summary of the Invention

[0004] This invention provides an electromechanical separation lock body and lock to solve the problem that mechanical emergency unlocking cannot operate normally in existing electronic lock bodies due to motor failure.

[0005] In a first aspect, the present invention provides an electromechanical separation lock body, comprising: Lock case; The transmission assembly is disposed within the lock housing; A linkage plate and an elastic reset member are disposed inside the lock housing. One end of the elastic reset member is connected to the lock housing, and the other end is connected to the linkage plate. The linkage plate is connected to the transmission assembly to move along a first direction under the drive of the transmission assembly and to reset in the opposite direction under the action of the elastic reset member. A motor assembly is disposed within the lock housing. The motor assembly includes a motor, a drive gear, and a driven gear meshing with the drive gear. The drive gear is connected to the output end of the motor. The electromechanical separation lock body has a mechanical locking state and a mechanical unlocking state. During the switching process between the mechanical locking state and the mechanical unlocking state, the linkage plate is driven by the transmission component to move along the first direction, and drives the driving gear to disengage from the driven gear.

[0006] Beneficial effects: This invention, by setting a linkage plate within the lock housing, and relying on a transmission component to drive the linkage plate to move in a specific direction, can actively cause the driving gear and driven gear to disengage during the switching between mechanical locking and unlocking states of the mechanical lock body. This avoids interference and locking of the mechanical transmission path in the event of motor failure, jamming, or stalling, ensuring that the mechanical emergency unlocking structure can independently and smoothly complete the unlocking action, thus improving the safety and emergency reliability of the lock body. Secondly, by setting an elastic reset component connecting the inner wall of the lock housing and the linkage plate within the lock housing, the linkage plate can be driven to reverse and reset after the mechanical unlocking or mechanical locking action is completed, allowing the driving gear and driven gear to re-engage stably, restoring the electric unlocking and electric locking functions. This achieves automatic and smooth switching between mechanical and electric modes without manual intervention, while also reducing wear caused by long-term continuous meshing of motor gears, further improving the operational stability and service life of the lock body.

[0007] In one alternative embodiment, the driven gear is rotatably mounted on the lock housing; the motor assembly further includes a motor housing for mounting the driving gear and the motor, wherein, as the connecting plate moves along the first direction, the connecting plate pushes the motor housing to move away from the driven gear.

[0008] Beneficial effects: Compared to directly driving the drive gear, this invention mounts the drive gear and motor onto the motor housing, forming an integral motion unit. The driven gear, on the other hand, is independently rotated and fixed in a lock housing position. Thus, under the pushing action of the connecting plate, the drive gear and driven gear can be quickly separated by moving the entire motor housing, eliminating the need for a separate, complex gear shifting structure. Furthermore, the overall movement of the motor housing offers better guidance and stability, ensuring the reliability of the disengagement action between the drive gear motor and the driven gear.

[0009] In one optional embodiment, the linkage plate is provided with a first slider, the motor housing is provided with a transmission plate, and the transmission plate is provided with a first sliding groove that slides in cooperation with the first slider. The first sliding groove includes a first sub-groove and a second sub-groove. The first sub-groove is arranged at an angle, one end of the first sub-groove is connected to the second sub-groove, and the other end is away from the second sub-groove and the driven gear. The second sub-groove extends along the first direction. During the movement of the linkage plate along the first direction, the first slider slides from the first sub-groove into the second sub-groove and pushes the transmission plate to move away from the driven gear.

[0010] Beneficial Effects: This invention, by setting a first slider on the connecting plate and opening a first groove on the transmission plate of the motor housing, consisting of an inclined first sub-groove and a second sub-groove extending along a first direction, enables the linear movement of the connecting plate along the first direction. The sliding cooperation between the slider and the groove smoothly transforms this linear movement into movement of the transmission plate and the motor housing away from the driven gear, achieving reliable separation of the driving and driven gears. Furthermore, the inclined first sub-groove provides gradual guidance and buffering during the initial stage of movement, preventing impact and jamming. The second sub-groove extending along the first direction positions and limits the motor housing after separation, ensuring a stable separation position. The overall structure is simple, the transmission is smooth, and the guidance is precise, ensuring thorough and reliable electromechanical separation while improving the structural stability and service life.

[0011] In one optional embodiment, the motor housing and / or the transmission plate are slidably connected to the lock housing; the motor housing and / or the transmission plate are provided with a first sliding member, and the lock housing is provided with a first sliding engagement member that slidably engages with the first sliding member; one of the first sliding member and the first sliding engagement member is a second slider, and the other is a second sliding groove; the inclination direction of the second sliding groove is consistent with the direction in which the first slider applies a force to the first sub-groove when the connecting plate moves along the first direction.

[0012] Beneficial effects: This invention achieves a sliding fit between the motor housing and / or transmission plate and the lock housing. Utilizing the guiding and limiting structure of the second slider and the second sliding groove, combined with the inclined arrangement of the second sliding groove to adapt to the force direction, the movement trajectory of the motor housing can be constrained and smoothly guided. Under the transmission action of the first slider and the inclined first sub-groove, the motor housing can smoothly slide along a preset direction, effectively counteracting the lateral force during transmission and preventing the motor housing from shifting, tilting, or jamming, thus making the gear disengagement action smoother. Simultaneously, this sliding guiding structure reduces frictional resistance between components, lowers the risk of motion interference, improves the motion accuracy and linkage stability of the electromechanical separation process, and ensures reliable overall structural fit, further guaranteeing the sensitivity and durability of the lock body's engagement and disengagement actions.

[0013] In one optional embodiment, the linkage plate is slidably connected to the lock housing, the linkage plate is provided with a plurality of second sliding members, and the lock housing is provided with a plurality of second sliding engagement members. One of the second sliding members and the second sliding engagement members is a third slider, and the other is a third sliding groove. The plurality of third sliding grooves extend along the first direction and are not collinear. At least one third slider is provided in any third sliding groove for sliding engagement.

[0014] Beneficial effects: This invention establishes a sliding connection between the connecting plate and the lock housing, and correspondingly sets multiple non-collinear third sliders and third grooves extending along the first direction on both the connecting plate and the lock housing. Through multi-point, non-collinear sliding cooperation, a stable directional constraint and support are formed for the connecting plate, effectively preventing swaying, wobble, jamming, or erratic movement of the connecting plate during its movement along the first direction, ensuring precise and consistent movement trajectory. Furthermore, multiple sliding points can distribute the force, improving the structural stability and load-bearing capacity of the connecting plate, ensuring smooth and reliable clutch transmission, thereby improving the accuracy and consistency of the separation and reset of the driving gear and driven gear, and extending the overall service life of the lock body.

[0015] In one optional embodiment, the transmission assembly includes a first transmission member that engages with the lock cylinder of the lock to drive the transmission. The first transmission member includes a first push plate and a second push plate, both of which are slidably connected to the lock housing. During the process of switching from the mechanical locking state to the mechanical unlocking state, the lock cylinder of the lock abuts against the first push plate and pushes it to slide along the first direction, thereby driving the linkage plate to move along the first direction; During the process of switching from the mechanical unlocking state to the mechanical locking state, the lock cylinder of the lock abuts against the second push plate and pushes it to slide along the first direction, thereby driving the linkage plate to move along the first direction.

[0016] Beneficial effects: In this invention, the first and second push plates slide along a first direction based on the rotation of the lock cylinder, corresponding to both mechanical unlocking and mechanical locking operation conditions. They can stably drive the connecting plate to move in either direction when the key is turned forward or backward, thereby triggering the disengagement of the driving gear and the driven gear. Furthermore, the sliding connection between the first and second push plates and the lock housing effectively reduces transmission friction and the risk of movement jamming.

[0017] In one optional embodiment, the transmission assembly further includes a second transmission member that engages with the handle of the lock. The second transmission member includes a rotating shaft and a gear set. The rotating shaft is connected to the handle of the lock to rotate relative to the lock housing under the drive of the handle. The gear set includes a locking gear and a locking gear paddle. The locking gear is sleeved on the rotating shaft, and the locking gear paddle is rotatably connected to the lock housing. The locking gear paddle has meshing teeth that engage with the locking gear. The locking gear paddle also has a driving end that abuts against the connecting plate. During the process of switching from the mechanical unlocking state to the mechanical locking state, the lock handle drives the rotating shaft, the locking gear, and the locking gear paddle to rotate. The driving end of the locking gear paddle abuts against the connecting plate and drives the connecting plate to move along the first direction.

[0018] Beneficial Effects: This invention, by setting a second transmission component that works in conjunction with the lock handle, utilizes a rotating shaft, a locking gear, and a locking gear lever to form the transmission path for driving the handle. When the handle performs a mechanical locking operation, the rotational motion of the handle is converted into the rotation of the locking gear lever. This rotation, through the drive end, stably pushes the connecting plate to move along the first direction, ensuring reliable separation of the driving gear and driven gear during the handle locking process. This achieves effective linkage between handle operation and the electromechanical separation mechanism. Furthermore, this structure allows handle locking and key operation to share the same clutch trigger mechanism, resulting in a simple transmission path and synchronized action response. It ensures thorough and interference-free electromechanical separation in handle mode, simplifies the internal layout of the lock body, and improves the versatility and operational stability of multi-mode mechanical unlocking.

[0019] In one optional embodiment, the first push plate is further provided with a rotating paddle hinged to the first push plate, and the rotating paddle is sleeved on the rotating shaft. During the process of switching from the mechanical locking state to the mechanical unlocking state, the lock handle drives the rotating paddle to rotate, and simultaneously drives the first push plate and the connecting plate to slide along the first direction.

[0020] Beneficial effects: By setting a rotating paddle on the first push plate and sleeved with the rotating shaft, the present invention enables the handle to synchronously drive the rotating paddle to rotate when the handle performs mechanical unlocking operation. This, in turn, causes the first push plate and the connecting plate to slide along a first direction, realizing direct linkage between the handle unlocking and the electromechanical separation mechanism. Furthermore, this structure allows key unlocking and handle unlocking to share the transmission path of the first push plate and the connecting plate, eliminating the need for a separate clutch drive structure for the handle. This effectively simplifies the internal components of the lock body, reduces the overall size, and ensures that the motor gear can quickly and reliably disengage during handle unlocking, improving the consistency and operational stability of multi-mode mechanical unlocking.

[0021] In one optional embodiment, the first push plate and the second push plate are provided with a plurality of third sliding members, and the lock housing is provided with a plurality of third sliding engagement members. One of the third sliding members and the third sliding engagement members is a fourth slider, and the other is a fourth sliding groove. The fourth sliding groove extends along the first direction, and at least one fourth slider is provided in each of the fourth sliding grooves for sliding engagement.

[0022] Beneficial effects: By setting multiple third sliding parts on the first and second push plates and multiple third sliding mating parts on the lock housing, the present invention enables the first and second push plates to form a multi-point sliding mating with the lock housing, which can form a stable directional constraint on the first and second push plates, effectively avoiding the first and second push plates from swaying, shaking or jamming during the sliding process, and ensuring the transmission accuracy and smooth operation when the lock cylinder drives the first or second push plate.

[0023] Secondly, the present invention also provides a lock, comprising: The aforementioned electromechanical separation lock body, wherein the transmission assembly includes a first transmission component and a second transmission component; The lock cylinder has a key slot for inserting a key, the lock cylinder is located inside the lock housing, and the lock cylinder has a lock cylinder dial at one end near the first transmission member; The handle is connected to the second transmission component inside the lock housing. During the switching process between the mechanical locking state and the mechanical unlocking state, the lock cylinder dial is driven by the key to abut against the first transmission member, and drives the connecting plate to move along the first direction, so as to disengage the driving gear from the driven gear. Alternatively, during the switching process between the mechanical locking state and the mechanical unlocking state, the second transmission member is driven by the handle to drive the connecting plate to move along the first direction and cause the driving gear to disengage from the driven gear.

[0024] Beneficial Effects: The lock provided by this invention offers three operating modes: key, handle, and motor. By integrating the aforementioned electromechanical separation lock body, when the key or handle performs the mechanical locking action, the lock cylinder drives the first transmission component or the handle drives the second transmission component, respectively. This causes the linkage plate to move in a specific direction and promptly disengages the driving gear from the driven gear, achieving physical isolation between mechanical and motor transmission. In this way, regardless of whether the motor malfunctions, experiences a power outage, or jams, the user can independently unlock the lock using the key or handle in an emergency, preventing mechanical unlocking failures or user entrapment. While retaining the ease of use of the intelligent motor, it effectively improves the product's safety and emergency reliability. In other words, the lock provided by this invention allows for seamless switching between the three operating modes—key, handle, and motor—without interference. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The following is combined with Figures 1 to 23 The following describes embodiments of the present invention.

[0030] According to embodiments of the present invention, in one aspect, such as Figure 1 , Figure 2 as well as Figure 4 As shown, an electromechanical separation lock body is provided, including: a lock shell 1, a transmission assembly, a connecting plate 2, an elastic reset member 9, and a motor assembly 3.

[0031] Specifically, the transmission assembly is disposed within the lock housing 1; the linkage plate 2 and the elastic reset member 9 are disposed within the lock housing 1, with one end of the elastic reset member 9 connected to the lock housing 1 and the other end connected to the linkage plate 2; the linkage plate 2 is connected to the transmission assembly for transmission, so as to move along the first direction under the drive of the transmission assembly and to reset in the opposite direction under the action of the elastic reset member 9; the motor assembly 3 is disposed within the lock housing 1, and the motor assembly 3 includes a motor, a drive gear 301, and a driven gear 302 meshing with the drive gear 301, with the drive gear 301 connected to the output end of the motor; the electromechanical separation lock body has a mechanical locking state and a mechanical unlocking state. During the switching process between the mechanical locking state and the mechanical unlocking state, the linkage plate 2 is driven by the transmission assembly to move along the first direction, and drives the drive gear 301 to disengage from the driven gear 302.

[0032] This invention, through the installation of a linkage plate 2 within the lock housing 1, allows for directional movement of the linkage plate 2 driven by a transmission component. This proactively disengages the drive gear 301 and driven gear 302 during the switching between locking and unlocking states of the mechanical lock body. This prevents interference and locking of the mechanical transmission path in case of motor failure, jamming, or stalling, ensuring the mechanical emergency unlocking structure can independently and smoothly complete the unlocking action, thus improving the lock body's safety and emergency reliability. Furthermore, by providing an elastic reset component 9 connecting the inner wall of the lock housing 1 to the linkage plate 2, the linkage plate 2 can be driven to reverse and reset after the mechanical unlocking or locking action is completed. This allows the drive gear 301 and driven gear 302 to re-engage stably, restoring the electric unlocking and electric locking functions. This achieves automatic and smooth switching between mechanical and electric modes without manual intervention, while also reducing wear caused by long-term continuous meshing of the motor gears, further improving the lock body's operational stability and service life.

[0033] Specifically, in this embodiment, the mechanical locking state and mechanical unlocking state of the electromechanical separation lock body refer to the working state of locking or unlocking by using the lock key or lock handle to drive the main bolt assembly 11 inside the lock shell 1 to extend or retract through a purely mechanical transmission method. This process does not rely on motor drive.

[0034] Specifically, in this embodiment, the first direction can be the length direction, width direction, or thickness direction of the electromechanical separation lock body, as long as it can meet the motion requirements of the linkage plate 2 moving in a direction under the drive of the transmission component and driving the motor assembly 3 to reliably disengage the drive gear 301 and the driven gear 302. This invention does not limit this.

[0035] Preferably, the first direction is the length direction of the electromechanical separation lock body. Compared with the width or thickness direction, the lock housing 1 has more internal space in the length direction, which can better accommodate the movement stroke of components such as the linkage plate 2, motor assembly 3, and transmission plate 304. This can not only avoid interference between moving parts, but also optimize the layout dimensions of the linkage mechanism, making the overall structure more compact and reasonable. At the same time, it ensures smoother and more stable movement of the linkage plate 2 and motor assembly 3, and improves the reliability of electromechanical separation and reset actions.

[0036] Specifically, in this embodiment, the resetting operation of the linkage plate 2 under the action of the elastic reset member 9 is performed after the main bolt assembly 11 has completed the extension (corresponding to mechanical locking) or retraction (corresponding to mechanical unlocking) operation. That is, when the key or handle drives the transmission assembly to complete the locking and unlocking action, and the main bolt assembly 11 is in place, the driving force of the transmission assembly on the linkage plate 2 disappears. At this time, the elastic reset member 9 releases elastic potential energy, driving the linkage plate 2 to reset in the opposite direction of the first direction, thereby pushing the motor housing 303 to move back, so that the driving gear 301 and the driven gear 302 re-mesh, restoring the electric operation function of the lock body, ensuring a smooth connection between mechanical operation and electric operation, and completing the mode switching without manual intervention, thus improving the ease of use of the lock body.

[0037] For example, the elastic reset component 9 can be, but is not limited to, an elastic component with elastic deformation and automatic reset capability, such as a spring, elastic rubber column, torsion spring, or sheet spring. Such a component can generate elastic deformation and store potential energy when the linkage plate 2 is displaced. After the external force is removed, it can rely on its own elasticity to recover the deformation and drive the linkage plate 2 to automatically return to its position. The structure is flexible and diverse, and can be adapted to different installation spaces and assembly requirements.

[0038] It should be noted that in this embodiment, the driven gear 302 is a structure that is in transmission cooperation with the main bolt assembly 11. Specifically, the motor drives the driven gear to rotate through the driving gear 301, which in turn drives the main bolt assembly 11 to complete the extension and retraction movement, thereby realizing the electric locking and unlocking of the lock. In this way, users can trigger the electric lock operation through intelligent methods such as fingerprint, password, and remote APP, enriching the usage modes of the lock and improving the convenience of daily opening and closing operations; at the same time, under mechanical operation conditions, the driving gear 301 and the driven gear 302 can disengage in time, isolating the motor transmission load and ensuring that the mechanical emergency opening and closing is not affected by the motor status.

[0039] Furthermore, such as Figure 1 , Figure 2 as well as Figure 6As shown, the driven gear 302 is rotatably mounted on the lock housing 1. The motor assembly 3 also includes a motor housing 303 for mounting the drive gear 301 and the motor. During the movement of the connecting plate 2 along the first direction, the connecting plate 2 pushes the motor housing 303 to move away from the driven gear 302. It can be understood that, compared to directly driving the drive gear 301, this embodiment of the invention mounts the drive gear 301 and the motor on the motor housing 303, making the motor and drive gear 301 form an integral motion unit, while the driven gear 302 is independently rotated and mounted in a fixed position on the lock housing 1. Thus, under the pushing action of the connecting plate 2, the drive gear 301 and driven gear 302 can be quickly separated by moving the motor housing 303 as a whole, without the need for a separate complex gear shifting structure. At the same time, the overall movement of the motor housing 303 has better guidance and stability, ensuring the reliability of the disengagement action between the drive gear 301, the motor, and the driven gear.

[0040] It should be noted that in this embodiment, the driven gear 302 is rotatably mounted on the lock housing 1, so that the driven gear 302 can rotate in the forward or reverse direction under the drive of the driving gear 301. In this way, the main bolt assembly 11 can be stably driven to extend or retract by the forward and reverse rotational motion, thereby completing the electric locking and unlocking actions of the lock respectively.

[0041] For example, when the safety component 18 of the electromechanical separation lock body is not engaged, the driven gear 302 rotates counterclockwise, causing the main bolt assembly 11 to extend out of the lock housing 1 in the second direction, thereby achieving locking. Conversely, when the safety component 18 of the electromechanical separation lock body is not engaged, the driven gear 302 rotates clockwise, causing the main bolt assembly 11 to retract into the lock housing 1 in the second direction, thereby achieving locking.

[0042] It should be noted that the fact that the safety component 18 of the aforementioned electromechanical separation lock body is not opened means that the safety structure inside the lock body is in a non-locked state with the limit released. The safety component 18 does not obstruct or constrain the main bolt assembly 11 or the mechanical transmission mechanism. The key and handle can normally perform mechanical locking and unlocking operations. The transmission assembly, linkage plate 2 and electromechanical separation mechanism can work together normally without being interfered with or restricted by the safety component 18.

[0043] Furthermore, the aforementioned second direction can be the length direction, width direction, or thickness direction of the electromechanical separation lock body. Preferably, the second direction is the width direction of the lock body.

[0044] Furthermore, such as Figure 5 and Figure 6As shown, the linkage plate 2 is provided with a first slider 201, and the motor housing 303 is provided with a transmission plate 304. The transmission plate 304 is provided with a first sliding groove 3041 that slides with the first slider 201. The first sliding groove 3041 includes a first sub-groove 30411 and a second sub-groove 30412. The first sub-groove 30411 is arranged at an angle. One end of the first sub-groove 30411 is connected to the second sub-groove 30412, and the other end is away from the second sub-groove 30412 and the driven gear 302. The second sub-groove 30412 extends along a first direction. During the movement of the linkage plate 2 along the first direction, the first slider 201 slides from the first sub-groove 30411 into the second sub-groove 30412 and pushes the transmission plate 304 to move away from the driven gear 302.

[0045] This invention, through the provision of a first slider 201 on the connecting plate 2 and a first groove 3041 formed by an inclined first sub-groove 30411 and a second sub-groove 30412 extending along a first direction on the transmission plate 304 of the motor housing 303, enables the linear movement of the connecting plate 2 along the first direction to be smoothly converted into the movement of the transmission plate 304 and the motor housing 303 away from the driven gear 302 through the sliding cooperation of the slider and the groove, thus achieving reliable separation of the driving gear 301 and the driven gear. Furthermore, the inclined first sub-groove 30411 provides gradual guidance and buffering in the initial stage of movement, avoiding impact and jamming. The second sub-groove 30412 extending along the first direction can position and limit the motor housing 303 after separation, ensuring stable separation. The overall structure is simple, the transmission is smooth, and the guidance is precise, ensuring thorough and reliable electromechanical separation while improving the operational stability and service life of the structure.

[0046] Specifically, in this embodiment, the first slider 201 can be a protruding structure such as a rivet, a protrusion, or an integrally formed limiting rib on the connecting plate 2, as long as it meets the requirements of sliding guidance and limiting cooperation. This embodiment does not limit the specific structural form of the first slider 201. Preferably, the first slider 201 is a rivet that can be detachably set on the connecting plate 2, which facilitates assembly and subsequent replacement and maintenance.

[0047] Specifically, in this embodiment, the first groove 3041 can be a groove extending along the first direction, or it can be a through hole extending along the first direction through the transmission plate 304.

[0048] Furthermore, such as Figure 3 and Figure 6As shown, the motor housing 303 and / or transmission plate 304 are slidably connected to the lock housing 1; the motor housing 303 and / or transmission plate 304 are provided with a first sliding member, and the lock housing 1 is provided with a first sliding engagement member that slides with the first sliding member. One of the first sliding member and the first sliding engagement member is a second slider 3031, and the other is a second slide groove 101. The inclination direction of the second slide groove 101 is consistent with the direction of the force applied by the first slider 201 to the first sub-groove 30411 when the connecting plate 2 moves along the first direction.

[0049] In this embodiment of the invention, the motor housing 303 and / or transmission plate 304 form a sliding fit with the lock housing 1. Utilizing the guiding and limiting structure of the second slider 3031 and the second slide groove 101, combined with the inclined arrangement of the second slide groove 101 to adapt to the force direction, the movement trajectory of the motor housing 303 can be constrained and smoothly guided. Under the transmission action of the first slider 201 and the inclined first sub-slot 30411, the motor housing 303 can smoothly slide along a preset direction, effectively counteracting the lateral force during transmission and preventing the motor housing 303 from shifting, tilting, or jamming, thus making the gear disengagement action smoother and more stable. Simultaneously, this sliding guiding structure reduces frictional resistance between components, lowers the risk of motion interference, improves the motion accuracy and linkage stability of the electromechanical separation process, and ensures reliable overall structural fit, further guaranteeing the sensitivity and durability of the lock body's clutch action.

[0050] It is understood that when both the motor housing 303 and the transmission plate 304 are slidably connected to the lock housing 1, the motor housing 303 and the transmission plate 304 are respectively provided with first sliding members, and the lock housing 1 is matched with a first sliding engagement member. By sliding and adapting the second slider 3031 to the inclined second slide groove 101, the movement trajectories of the motor housing 303 and the transmission plate 304 can be independently guided and limited, so that the two can slide smoothly in sync with the displacement of the connecting plate 2.

[0051] In one example, such as Figure 3 and Figure 6 As shown, the lock housing 1 is provided with a pair of second sliding grooves 101. The motor housing 303 and the transmission plate 304 are respectively fitted with slidingly fitted second sliders 3031, and each second slider 3031 is embedded in the second sliding groove 101. The second sliding groove 101 is a strip-shaped hole provided on the lock housing 1, and the second slider 3031 is a strip-shaped protrusion adapted to the second sliding groove 101.

[0052] It should be noted that the number of the second slide groove 101 and the second slider 3031 is not limited to two; it can also be one or more.

[0053] In some embodiments, such as Figure 1 , Figure 3 as well as Figure 4 As shown, the linkage plate 2 is slidably connected to the lock housing 1. The linkage plate 2 is provided with a plurality of second sliding members, and the lock housing 1 is provided with a plurality of second sliding engagement members. One of the second sliding members and the second sliding engagement members is a third slider 102, and the other is a third slide groove 202. The plurality of third slide grooves 202 extend along the first direction and are not collinear. At least one third slider 102 is provided in any third slide groove 202 for sliding engagement with it.

[0054] In this embodiment of the invention, the connecting plate 2 and the lock housing 1 are slidably connected. Multiple third sliders 102 and third grooves 202, extending along a first direction and not collinear, are correspondingly provided on the connecting plate 2 and the lock housing 1. Through multi-point, non-collinear sliding cooperation, a stable directional constraint and support are formed on the connecting plate 2, effectively preventing swaying, deflection, jamming, or erratic movement of the connecting plate 2 during its movement along the first direction, ensuring precise and consistent movement trajectory. Furthermore, multiple sliding points can distribute the force, improving the structural stability and load-bearing capacity of the connecting plate 2, ensuring smooth and reliable clutch transmission, thereby improving the accuracy and consistency of the separation and resetting of the driving gear 301 and the driven gear 302, and extending the overall service life of the lock body.

[0055] Specifically, in this embodiment, the third slider 102 can be a protruding structure such as a rivet, a protrusion, or a limiting rib, as long as it meets the requirements of sliding guidance and limiting cooperation. This embodiment does not limit the specific structural form of the third slider 102.

[0056] Specifically, in this embodiment, the third groove 202 can be a groove extending in the first direction or a through hole extending in the first direction through the connecting plate 2.

[0057] In one example, the third slider 102 is a rivet detachably mounted on the lock housing 1, and the third slide groove 202 is a through hole extending along the first direction on the connecting plate 2.

[0058] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, the transmission assembly includes a first transmission component that cooperates with the lock cylinder of the lock. The first transmission component includes a first push plate 4 and a second push plate 5, both of which are slidably connected to the lock housing 1. During the process of switching from a mechanical locking state to a mechanical unlocking state, the lock cylinder of the lock abuts against the first push plate 4 and pushes it to slide along a first direction, thereby driving the linkage plate 2 to move along the first direction. During the process of switching from a mechanical unlocking state to a mechanical locking state, the lock cylinder of the lock abuts against the second push plate 5 and pushes it to slide along the first direction, thereby driving the linkage plate 2 to move along the first direction.

[0059] In this embodiment of the invention, the first push plate 4 and the second push plate 5 slide along the first direction based on the rotation of the lock cylinder, corresponding to two operating conditions: mechanical unlocking and mechanical locking, respectively. They can stably drive the connecting plate 2 to move in either direction when the key is turned forward or backward, thereby triggering the disengagement of the driving gear 301 and the driven gear 302. Furthermore, the first push plate 4 and the second push plate 5 are slidably connected to the lock housing 1, which effectively reduces transmission friction and the risk of movement jamming.

[0060] Specifically, in this embodiment, the first push plate 4 and the second push plate 5 can be offset from the connecting plate 2 along the thickness direction of the electromechanical separation lock body. Rivets, columnar protrusions, or other protruding structures are provided on the side of the first push plate 4 and the second push plate 5 near the connecting plate 2, and these protruding structures abut against the peripheral sidewall of the connecting plate 2. In this way, on the one hand, the offset layout in the thickness direction makes the internal space arrangement of the lock body more compact and reasonable, thereby reducing the overall space occupied by the electromechanical separation lock body; on the other hand, when the first push plate 4 or the second push plate 5 moves, the protruding structures on it can effectively transmit the force to the connecting plate 2, pushing the connecting plate 2 to slide smoothly on the lock shell 1, achieving the required transmission function.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figure 9 as well as Figure 10 As shown, the transmission assembly also includes a second transmission component that cooperates with the handle of the lock. The second transmission component includes a rotating shaft 6 and a gear set 7. The rotating shaft 6 is connected to the handle of the lock so that it rotates relative to the lock housing 1 under the drive of the handle of the lock. The gear set 7 includes a locking gear 701 and a locking gear paddle 702. The locking gear 701 is sleeved on the rotating shaft 6, and the locking gear paddle 702 is rotatably connected to the lock housing 1. The locking gear paddle 702 has meshing teeth 7021 that mesh with the locking gear 701. The locking gear paddle 702 also has a driving end 7022 that abuts against the connecting plate 2. During the process of switching from the mechanical unlocking state to the mechanical locking state, the lock handle drives the rotating shaft 6, the locking gear 701 and the locking gear paddle 702 to rotate. The driving end 7022 of the locking gear paddle 702 abuts against the connecting plate 2 and drives the connecting plate 2 to move in the first direction.

[0062] This invention, through the provision of a second transmission component that works in conjunction with the lock handle, utilizes a rotating shaft 6, a locking gear 701, and a locking gear lever 702 to form the transmission path for driving the handle. This allows the handle's rotational motion to be converted into the rotation of the locking gear lever 702 during mechanical locking, and the drive end 7022 stably pushes the connecting plate 2 to move along a first direction. This ensures reliable separation of the driving gear 301 and the driven gear 302 during the handle locking process, achieving effective linkage between handle operation and the electromechanical separation mechanism. Furthermore, this structure allows handle locking and key operation to share the same clutch trigger mechanism, resulting in a simple transmission path and synchronized action response. It ensures thorough and interference-free electromechanical separation in handle mode, simplifies the internal layout of the lock body, and improves the versatility and operational stability of multi-mode mechanical unlocking.

[0063] Specifically, in this embodiment, such as Figure 2 , Figure 9 as well as Figure 10 As shown, the locking gear 701 and the locking gear paddle 702 are provided with meshing teeth 7021 only on the side closest to each other. In this way, meshing transmission can only be achieved when the two rotate to the position where the teeth are opposite. When the two rotate relative to each other and are misaligned, the teeth will separate and the meshing relationship will be released.

[0064] Specifically, in this embodiment, the locking gear lever 702 and the linkage plate 2 can be misaligned along the thickness direction of the electromechanical separation lock body. For example, as shown... Figure 2 As shown, the locking gear lever 702 is located on the side of the connecting plate 2 away from the first push plate 4. Furthermore, the driving end 7022 of the locking gear lever 702 can abut against the connecting plate 2 because the connecting plate 2 has a protruding structure that abuts against the driving end 7022 of the locking gear lever. For example, the protruding structure can be an integrally stamped bulge or a welded and fixed limiting rivet.

[0065] Furthermore, such as Figure 2 and Figure 7 As shown, the first push plate 4 is also provided with a rotating paddle 401 hinged to the first push plate 4, and the rotating paddle 401 is sleeved on the rotating shaft 6; during the process of switching from the mechanical locking state to the mechanical unlocking state, the lock handle drives the rotating paddle 401 to rotate, and at the same time drives the first push plate 4 and the connecting plate 2 to slide along the first direction.

[0066] In this embodiment of the invention, a rotating paddle 401, sleeved with a rotating shaft 6, is provided on the first push plate 4. When the handle performs a mechanical unlocking operation, the rotating paddle 401 is synchronously driven to rotate by the handle, thereby causing the first push plate 4 and the connecting plate 2 to slide along a first direction, achieving direct linkage between the handle unlocking and the electromechanical separation mechanism. Furthermore, this structure allows key unlocking and handle unlocking to share the transmission path of the first push plate 4 and the connecting plate 2, eliminating the need for a separate clutch drive structure for the handle. This effectively simplifies the internal components of the lock body, reduces the overall size, and ensures that the motor gear can quickly and reliably disengage during handle unlocking, improving the consistency and operational stability of multi-mode mechanical unlocking.

[0067] In some embodiments, such as Figure 1 , Figure 2 , Figure 7 as well as Figure 8 As shown, the first push plate 4 and the second push plate 5 are provided with a plurality of third sliding members, and the lock housing 1 is provided with a plurality of third sliding engagement members. One of the third sliding members and the third sliding engagement members is a fourth slider 103, and the other is a fourth slide groove 402. The fourth slide groove 402 extends along the first direction, and at least one fourth slider 103 is provided in any fourth slide groove 402 for sliding engagement with it.

[0068] The embodiments of the present invention provide multiple third sliding members on the first push plate 4 and the second push plate 5, and multiple third sliding mating members on the lock housing 1. This enables the first push plate 4 and the second push plate 5 to form a multi-point sliding mating with the lock housing 1, thereby providing a stable directional constraint on the first push plate 4 and the second push plate 5. This effectively prevents the first push plate 4 and the second push plate 5 from swaying, shaking, or jamming during the sliding process, ensuring the transmission accuracy and smooth operation when the lock cylinder drives the first push plate 4 or the second push plate 5.

[0069] Specifically, in this embodiment, the fourth slider 103 can be a protruding structure such as a rivet, a protrusion, or a limiting rib, as long as it meets the requirements of sliding guidance and limiting cooperation. This embodiment does not limit the specific structural form of the fourth slider 103.

[0070] Specifically, in this embodiment, the fourth groove 402 can be a groove extending along the first direction, or a through hole extending along the first direction formed through the first push plate 4, the second push plate 5, or the lock shell 1.

[0071] Preferably, the lock housing 1 is provided with a plurality of fourth sliders 103, and the first push plate 4 and the second push plate 5 are respectively provided with two fourth sliding grooves 402.

[0072] According to an embodiment of the present invention, another aspect provides a lock, including: the above-described electromechanically separate lock body, lock cylinder, and handle.

[0073] Specifically, such as Figure 1 As shown, the transmission assembly includes a first transmission component and a second transmission component; the lock cylinder has a key slot for key insertion, the lock cylinder is located inside the lock housing 1, and a lock cylinder dial 8 is provided at one end of the lock cylinder near the first transmission component; the handle is connected to the second transmission component inside the lock housing 1; during the switching process between the mechanical locking state and the mechanical unlocking state, the lock cylinder dial 8 is driven by the key to abut against the first transmission component, and drives the connecting plate 2 to move along the first direction, so as to disengage the driving gear 301 from the driven gear 302; or, during the switching process between the mechanical locking state and the mechanical unlocking state, the second transmission component is driven by the handle to drive the connecting plate 2 to move along the first direction, and drives the driving gear 301 from the driven gear 302 to disengage.

[0074] The lock provided in this invention has three operating modes: key, handle, and motor. By integrating the aforementioned electromechanical separation lock body, when the key or handle performs the mechanical locking action, the lock cylinder drives the first transmission component or the handle drives the second transmission component, respectively. This causes the linkage plate 2 to move in a specific direction and promptly disengages the driving gear 301 from the driven gear 302, achieving physical isolation between mechanical and motor transmission. In this way, regardless of whether the motor malfunctions, experiences a power outage, or jams, the user can independently unlock the lock using the key or handle in an emergency, preventing mechanical unlocking failures or user entrapment. While retaining the ease of use of the intelligent motor, it effectively improves the product's safety and emergency reliability. In other words, the lock provided by this invention allows for seamless switching between the three operating modes—key, handle, and motor—without interference.

[0075] Specifically, in this embodiment, the first transmission component includes the first push plate 4 and the second push plate 5 mentioned above, and the second transmission component includes the rotating shaft 6 and the gear set 7 mentioned above.

[0076] The following describes the three operating logics for opening and closing the lock in the embodiments of the present invention.

[0077] It should be noted in advance that, if Figures 11 to 21 As shown, the electromechanical separation lock body also includes a main bolt turntable 10, a main bolt assembly 11, a handle dial 12, a handle linkage plate 13, a handle turntable 14, a motor linkage plate 15, a latch bolt 16, and a latch bolt lever 17.

[0078] Scenario 1: Under the premise of using the key to unlock and the safety component 18 is not activated.

[0079] like Figure 2As shown, after the key is inserted into the key slot of the lock cylinder, the key drives the lock cylinder dial 8 to rotate clockwise. During the rotation of the lock cylinder dial 8, the first push plate 4 is pushed simultaneously, causing the first push plate 4 to slide along the first direction with the help of the fourth slider 103 and the fourth slide groove 402. Then, the protrusion structure on the first push plate 4 pushes the connecting plate 2, causing the connecting plate 2 to slide along the first direction with the help of the third slide groove 202 and the third slider 102. Then, the first slider 201 on the connecting plate 2 slides from the first sub-slot 30411 of the transmission plate 304 to the second sub-slot 30412 of the transmission plate 304, so as to push the motor housing 303 and the transmission plate 304 to move a certain distance along the second slide groove 101 on the lock housing 1, thereby disengaging the driving gear 301 and the driven gear 302.

[0080] like Figure 1 , Figure 2 , Figure 12 as well as Figure 14 As shown, after the driving gear 301 and the driven gear 302 disengage, the first push plate 4 continues to move along the first direction and abuts against the first rivet 1001 on the main bolt turntable 10, causing the main bolt turntable 10 to rotate clockwise. This causes the second rivet 1002 on the main bolt turntable 10 to drive the guide groove of the main bolt assembly 11, causing the main bolt assembly 11 to retract into the lock housing 1. At the same time, the rotating paddle 401 on the first push plate 4 rotates, causing the tongue 16 to retract into the lock housing 1, thereby unlocking.

[0081] Scenario 2: When the key is used to lock the car and the safety component 18 is not activated.

[0082] like Figure 2 As shown, after the key is inserted into the key slot of the lock cylinder, the key drives the lock cylinder dial 8 to rotate counterclockwise. During the rotation of the lock cylinder dial 8, the second push plate 5 is pushed simultaneously, causing the second push plate 5 to slide along the first direction with the help of the fourth slider 103 and the fourth slide groove 402. Then, the protrusion structure on the second push plate 5 pushes the connecting plate 2, causing the connecting plate 2 to slide along the first direction with the help of the third slide groove 202 and the third slider 102. Then, the first slider 201 on the connecting plate 2 slides from the first sub-slot 30411 of the transmission plate 304 to the second sub-slot 30412 of the transmission plate 304, so as to push the motor housing 303 and the transmission plate 304 to move a certain distance along the second slide groove 101 on the lock housing 1, thereby disengaging the driving gear 301 and the driven gear 302.

[0083] like Figure 1 , Figure 2 , Figure 12 as well as Figure 14As shown, after the driving gear 301 and the driven gear 302 disengage, the second push plate 5 will continue to move along the first direction and abut against the third rivet 1003 on the main bolt turntable 10, causing the main bolt turntable 10 to rotate counterclockwise. This causes the second rivet 1002 on the main bolt turntable 10 to drive the guide groove of the main bolt assembly 11, causing the main bolt assembly 11 to extend out of the lock case 1, thereby achieving locking.

[0084] Scenario 3: When using a key to unlock the door and the safety component 18 is not activated.

[0085] like Figure 2 As shown, when the handle is rotated clockwise, that is, when the rotating shaft 6 rotates clockwise, the rotating shaft 6 will drive the rotating paddle 401 on the first push plate 4 to rotate, and at the same time drive the first push plate 4 to slide along the first direction. Then, the protruding structure on the first push plate 4 will push the connecting plate 2, so that the connecting plate 2 slides along the first direction with the help of the third slide groove 202 and the third slider 102. Then, the first slider 201 on the connecting plate 2 will slide from the first sub-slot 30411 of the transmission plate 304 to the second sub-slot 30412 of the transmission plate 304, so as to push the motor housing 303 and the transmission plate 304 to move a certain distance along the second slide groove 101 on the lock housing 1, thereby disengaging the driving gear 301 and the driven gear 302.

[0086] like Figure 1 , Figure 2 , Figure 12 as well as Figure 14 As shown, after the driving gear 301 and the driven gear 302 disengage, the first push plate 4 continues to move in the first direction and abuts against the first rivet 1001 on the main bolt turntable 10, causing the main bolt turntable 10 to rotate clockwise. This causes the second rivet 1002 on the main bolt turntable 10 to drive the guide groove 1101 of the main bolt assembly 11, causing the main bolt assembly 11 to retract into the lock housing 1. At the same time, the rotating paddle 401 on the first push plate 4 rotates, causing the tongue 16 to retract into the lock housing 1, thereby unlocking.

[0087] Scenario 4: When the key is used to lock the car and the safety component 18 is not activated.

[0088] like Figure 2As shown, when the handle is rotated counterclockwise, that is, when the rotating shaft 6 rotates counterclockwise, the rotating shaft 6 drives the locking gear 701, and the locking gear 701 drives the locking gear paddle 702 to rotate clockwise. The driving end 7022 of the locking gear paddle 702 actuates the protruding structure on the connecting plate 2, so that the connecting plate 2 slides along the first direction by means of the third slide groove 202 and the third slider 102. Then, the first slider 201 on the connecting plate 2 will slide from the first sub-slot 30411 of the transmission plate 304 to the second sub-slot 30412 of the transmission plate 304, so as to push the motor housing 303 and the transmission plate 304 to move a certain distance along the second slide groove 101 on the lock housing 1, thereby disengaging the driving gear 301 and the driven gear 302.

[0089] At this time, the handle dial 12 sleeved on the rotating shaft 6 will drive the handle linkage plate 13 set on the housing to rotate clockwise, and the handle linkage plate 13 will drive the handle turntable 14 on the same axis. Specifically, the slider 1401 on the handle turntable 14 and the guide groove 1301 on the handle linkage plate 13 will drive the handle turntable 14 to rotate clockwise. At the same time, the handle turntable 14 will drive the main bolt turntable 10 to rotate counterclockwise, so that the second rivet 1002 on the main bolt turntable 10 will drive the guide groove 1101 of the main bolt assembly 11 to extend the main bolt assembly 11 out of the lock case 1, thereby realizing locking.

[0090] Scenario 5: Under the premise of unlocking by using the motor and the safety component 18 not being opened.

[0091] like Figure 1 , Figure 12 , Figure 14 , Figure 22 as well as Figure 23 As shown, the drive gear 301 rotates counterclockwise, driving the driven gear 302 to rotate clockwise, which in turn drives the motor linkage plate 15 located inside the lock housing 1 to rotate counterclockwise. The motor linkage plate 15 abuts against the protruding structure on the handle linkage plate 13, causing the handle turntable 14 to rotate counterclockwise. Since the handle turntable 14 and the main bolt turntable 10 are driven by gear meshing, the handle turntable 14 will drive the main bolt turntable 10 to rotate clockwise, thereby causing the second rivet 1002 on the main bolt turntable 10 to drive the guide groove 1101 of the main bolt assembly 11 to retract the main bolt assembly 11 into the lock housing 1. Meanwhile, since the lock housing 1 is also equipped with a motor linkage plate 15 that meshes with the driven gear 302, when the driven gear 302 rotates clockwise, the motor linkage plate 15 will rotate counterclockwise, and drive the tongue lever 17 sleeved on the rotating shaft 6 to rotate clockwise. The tongue lever 17 drives the tongue 16 to retract into the lock housing 1, thereby unlocking.

[0092] Situation 6: When the motor is locked and the safety component 18 is not activated.

[0093] like Figure 1 , Figure 12 , Figure 14 , Figure 22 as well as Figure 23 As shown, the driving gear 301 rotates clockwise, driving the driven gear 302 to rotate counterclockwise, which in turn drives the motor connecting plate 15 located inside the lock housing 1 to rotate clockwise. The motor connecting plate 15 abuts against the protruding structure on the handle connecting plate 13, driving the handle turntable 14 to rotate clockwise. At the same time, the handle turntable 14 drives the main bolt turntable 10 to rotate counterclockwise, thereby causing the second rivet 1002 on the main bolt turntable 10 to drive the guide groove 1101 of the main bolt assembly 11 to extend the main bolt assembly 11 out of the lock housing 1, thus achieving locking.

[0094] It should be noted that the rotation directions of the lock cylinder, handle, and drive gear described above do not correspond uniquely to the unlocking and locking actions of the lock. They are merely exemplary rotational engagement methods listed in this embodiment in conjunction with a specific structural layout. In different lock body structures, component arrangements, and transmission paths, the rotation directions of each driving component can be flexibly changed by adjusting the gear meshing method, the paddle installation angle, the engagement position of the connecting plate, and other structural designs, all of which can achieve the same unlocking and locking functions. This should not be used to limit the scope of protection of this invention.

[0095] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
