Description

Technical Field

[0001] This application belongs to the field of security product technology, specifically relating to a lock. Background Technology

[0002] As user demands increase, users are becoming more security-conscious. More and more users are upgrading the locks installed in their homes. The related technology involves locks equipped with electric drive mechanisms. In this mode, the electric drive mechanism moves the lock cylinder, thus opening and closing the lock. Of course, to allow for flexible use, these locks also include manual drive mechanisms, which can also move the lock cylinder and thus open and close the lock in the same way.

[0003] During the manual operation of the lock cylinder, the manual drive mechanism needs to overcome the transmission resistance from the electric drive mechanism, which makes manual operation feel strenuous for the user. This not only affects the efficiency of the manual drive but also provides a poor user experience. Summary of the Invention

[0004] This invention discloses a lock to solve the problem of laborious manual operation of locks.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] This application provides a lock, including an electric drive mechanism, a manual knob, and a lock cylinder. The electric drive mechanism has a power-engaged state and a power-disengaged state. The manual knob is connected to the lock cylinder, wherein:

[0007] When the electric drive mechanism is in the power engagement state, the electric drive mechanism is connected to the lock cylinder drive, and the electric drive mechanism can drive the lock cylinder to move;

[0008] When the electric drive mechanism is in the power-disengaged state, the electric drive mechanism is power-disengaged from the lock cylinder, and the movement of the manual knob can drive the lock cylinder to move.

[0009] The technical solution adopted in this invention can achieve the following technical effects:

[0010] In the lock disclosed in this application embodiment, when the electric drive mechanism is in a powered engagement state, it can drive the lock cylinder to move, thereby locking or unlocking the lock. When the electric drive mechanism is in a powered disengaged state, the power transmission between it and the lock cylinder is cut off. At this time, the lock cylinder can be driven by a manual knob, thereby locking or unlocking the lock. Based on this setting, the lock in this application embodiment can achieve power disengagement from the lock cylinder when the electric drive mechanism malfunctions, so that the electric drive mechanism will not obstruct the movement of the lock cylinder. Therefore, when the lock cylinder is driven by the manual knob, there will be no transmission resistance from the electric drive mechanism, allowing users to more easily lock or unlock manually, thus improving the user experience.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Please refer to Figures 1 to 10 This application discloses a lock, which includes an electric drive mechanism 100, a manual knob 200, and a lock cylinder 300. The electric drive mechanism 100 and the manual knob 200 can serve as power components for the movement of the lock cylinder 300, so as to lock or unlock the lock.

[0029] The electric drive mechanism 100 has a power-engaged state and a power-disengaged state, and can switch between the two states. When in the power-engaged state, the electric drive mechanism 100 can transmit driving force to the lock cylinder 300 to drive the lock cylinder 300 to move; when in the power-disengaged state, the electric drive mechanism 100 cannot transmit driving force to the lock cylinder 300.

[0030] The manual knob 200 is connected to the lock cylinder 300. The manual knob 200 can drive the lock cylinder 300 to move, so that the lock can be locked or unlocked manually.

[0031] Based on the above configuration, when the electric drive mechanism 100 is in the power-engaged state, the electric drive mechanism 100 is connected to the lock cylinder 300, and the electric drive mechanism 100 can drive the lock cylinder 300 to move, so as to lock or unlock the lock in an electric manner; when the electric drive mechanism 100 is in the power-disengaged state, the electric drive mechanism 100 is disconnected from the lock cylinder 300, and at this time, the lock cylinder 300 can be driven to move by the movement of the manual knob 200, so as to lock or unlock the lock in a manual manner.

[0032] In this embodiment, the lock can disconnect the power transmission between itself and the lock cylinder 300 by switching to a power separation state when the electric drive mechanism 100 malfunctions. This prevents the electric drive mechanism 100 from obstructing the movement of the lock cylinder 300, and ensures that the lock cylinder 300 is not subjected to transmission resistance from the electric drive mechanism 100 when the manual knob 200 drives it. This allows users to more easily lock or unlock the lock, improving the user experience.

[0033] refer to Figures 1 to 6 In some embodiments, the electric drive mechanism 100 may include a power source 110, a first transmission member 120, and a second transmission member 130. The power source 110 is connected to the first transmission member 120, and the second transmission member 130 is movably disposed on the lock cylinder 300 and can switch between a first position and a second position relative to the lock cylinder 300. Based on this, in the first position, the second transmission member 130 is connected to the first transmission member 120, so that the electric drive mechanism 100 is in a powered engagement state. At this time, the power source 110 can sequentially drive the lock cylinder 300 to move via the first transmission member 120 and the second transmission member 130. In the second position, the second transmission member 130 is separated from the first transmission member 120, so that the electric drive mechanism 100 is in a powered disengaged state.

[0034] For example, such as Figure 1 and Figure 5 As shown, the power source 110 may include a drive motor and a gear mechanism 140. The gear mechanism 140 includes a gear carrier 141 and a gear set 142. The gear set 142 is rotatably mounted on the gear carrier 141 and is stably installed through the gear carrier 141. The power input gear in the gear set 142 is connected to the drive motor for transmission, so as to drive the gear set 142 to rotate relative to the gear carrier 141 through the drive motor.

[0035] Furthermore, in order to transmit power to the first transmission member 120, the first transmission member 120 may have a first gear 122, which meshes with the power output gear in the gear set 142. In this way, the drive motor can transmit power to the first gear 122 through the gear set 142, thereby driving the first transmission member 120 to rotate.

[0036] When the second transmission component 130 is in the first position, it is connected to the first transmission component 120, so that the second transmission component 130 can be rotated under the drive of the drive motor, and then the electric lock cylinder 300 can be rotated through the second transmission component 130 to lock or unlock the lock.

[0037] Based on the above settings, this application embodiment realizes the clutch of the electric drive mechanism 100 within this application by switching the clutch state between the first transmission member 120 and the second transmission member 130. This clutch method is relatively easy to implement, has a relatively simple structure, and has relatively high reliability.

[0038] Of course, other clutch methods can also be used. In other embodiments, the clutch state can be switched between the electric drive mechanism 100 and the lock cylinder 300. Specifically, in the power engagement state, the output end of the electric drive mechanism 100 is connected to the lock cylinder 300 to drive the lock cylinder 300 to move; in the power disengagement state, the output end of the electric drive mechanism 100 is separated from the lock cylinder 300 so that the lock cylinder 300 can be driven manually in the future.

[0039] In some embodiments, the first transmission member 120 may be a cylindrical transmission member, which is sleeved on the lock cylinder 300. Exemplarily, the first transmission member 120 may have a cylindrical structure with an inner cavity, which provides housing space for the lock cylinder 300 and also protects the lock cylinder 300. This effectively reduces the size of the lock and prevents the lock cylinder 300 from malfunctioning due to external environmental influences. Of course, the first transmission member 120 may also have other cylindrical shapes; the specific shape is not limited.

[0040] The second transmission member 130 can be a sliding member, which is movably disposed in the lock cylinder 300 so as to move and switch between the first position and the second position by sliding.

[0041] refer to Figure 2 and Figure 6In order to realize the connection between the second transmission component 130 and the first transmission component 120, the inner wall of the cylindrical transmission component can be provided with a connecting groove 121, and the sliding component can be correspondingly set with the connecting groove 121. By moving the sliding component between the first position and the second position, the relative relationship between the sliding component and the connecting groove 121 can be changed, thereby switching the connection state between the first transmission component 120 and the second transmission component 130.

[0042] For example, the inner wall of the cylindrical transmission member may be provided with a plurality of connecting grooves 121, which are arranged at intervals around the circumference of the cylindrical transmission member. Based on this, when the cylindrical transmission member is rotated, the sliding member can be made to cooperate with any of the connecting grooves 121, thereby shortening the time interval between the relative misalignment of the sliding member and the connecting groove 121, and thus improving the engagement speed between the first transmission member 120 and the second transmission member 130.

[0043] In the first position, at least a portion of the sliding member is inserted into the connecting groove 121 and can drive the lock cylinder 300 to rotate with the rotation of the cylindrical transmission member. In the second position, the sliding member is separated from the connecting groove 121, and the manual knob 200 can drive the lock cylinder 300 and the sliding member to rotate relative to the cylindrical transmission member. Based on this, the embodiments of this application use a method of mutual insertion between the sliding member and the connecting groove 121 to achieve engagement or separation. This plug-in structure is relatively simple, easy to implement, and has good engagement stability and reliability.

[0044] Of course, other methods can also be used to achieve the combination or separation. In other embodiments, the first transmission member 120 and the second transmission member 130 can also be combined and separated by magnetic attraction. Specifically, when combination is required, the first transmission member 120 and the second transmission member 130 can be magnetically attracted to ensure that they can move synchronously; when separation is required, the magnetic attraction between the first transmission member 120 and the second transmission member 130 can be eliminated to separate their transmission. For example, one of the first transmission member 120 and the second transmission member 130 is an electromagnet and the other is an iron block. Alternatively, both can be electromagnets, and the combination or separation state between the first transmission member 120 and the second transmission member 130 can be switched by changing the energizing state.

[0045] Continue to refer to Figure 2 and Figure 6 To ensure that the sliding member switches between the first and second positions according to a preset trajectory, the lock cylinder 300 may be provided with a guide space 301. The sliding member is guided and cooperates with the guide space 301. This can improve the stability and accuracy of sliding, ensure that the sliding member can be precisely cooperated with the connecting groove 121, and also improve the torsional torque borne by the sliding member, so as to ensure that a stable transmission connection is formed between the first transmission member 120 and the second transmission member 130.

[0046] For example, the lock cylinder 300 may have two spaced-apart guide blocks 303, forming a guide space 301 between the two guide blocks 303. In other embodiments, the lock cylinder 300 may also have a guide groove recessed into the surface of the lock cylinder 300, in which case the space enclosed by the guide groove is the guide space 301. Of course, it can also be any other structure with a guiding function, which is not specifically limited here.

[0047] To switch between the engaged and disengaged states of the first transmission component 120 and the second transmission component 130, the second transmission component 130 can be disengaged from the first transmission component 120 by manually rotating the knob 200. Of course, the engagement of the second transmission component 130 with the first transmission component 120 can also be driven by the manual knob 200, or other driving methods can be used, such as elastic driving method, magnetic driving method, etc.

[0048] refer to Figure 3 and Figure 4 In some embodiments, the manual knob 200 may include a toggle protrusion 210, and correspondingly, the slider may include a mating protrusion 131. The mating protrusion 131 slides in conjunction with the toggle protrusion 210. The slider can slide from a first position to a second position and drive the lock cylinder 300 to rotate as the manual knob 200 rotates through the sliding engagement of the mating protrusion 131 and the toggle protrusion 210.

[0049] Specifically, when the electric drive mechanism 100 is in normal condition, the sliding member is engaged with the connecting groove 121. In this case, the first transmission member 120 can transmit the power of the power source 110 to the second transmission member 130 through the connecting groove 121, thereby driving the lock cylinder 300 to rotate through the second transmission member 130 to lock or unlock the lock.

[0050] When the electric drive mechanism 100 malfunctions, to prevent it from obstructing the rotation of the lock cylinder 300, the manual knob 200 can be turned. When the protrusion 210 is turned, it exerts a force on the mating protrusion 131, causing the sliding member to move from the first position to the second position. This disengages the sliding member from the connecting groove 121, thereby achieving power separation between the first transmission member 120 and the second transmission member 130. Thus, as the manual knob 200 rotates, the lock cylinder 300 rotates. The second transmission member 130 can rotate with the lock cylinder 300, while the first transmission member 120 and even the power source 110 connected to the first transmission member 120 cannot receive power from the second transmission member 130 and will not move. In other words, the manual knob 200 can easily drive the lock cylinder 300 to rotate, thus greatly reducing the driving force required for the lock cylinder 300 to rotate, making the locking or unlocking process of the lock easier and improving the user experience.

[0051] Based on the above settings, the embodiment of this application can achieve both power separation and drive the lock cylinder 300 to rotate through the manual knob 200, achieving the effect of dual use in one device. This can improve the ease of operation to a certain extent and make the structure simpler.

[0052] In other embodiments, the sliding member can be moved and switched between the first position and the second position using other driving methods, such as: using a linear motor driving method, using a button pressing driving method, using a wrench pulling driving method, using a cam driving method, etc., and the specific driving method is not limited.

[0053] Continue to refer to Figure 3 and Figure 4 In some embodiments, the actuating protrusion 210 may be an annular protrusion, with the mating protrusion 131 extending into the space enclosed by the actuating protrusion 210 and slidably contacting the inner wall of the space enclosing the actuating protrusion 210. This arrangement ensures that the mating protrusion 131 is always within the closed space enclosed by the annular protrusion, thereby preventing the actuating protrusion 210 from separating from the mating protrusion 131 and thus preventing the inability to switch the position of the sliding member.

[0054] For example, the annular protrusion may include a first abutting wall and a second abutting wall, wherein the first abutting wall and the second abutting wall are connected and set at an included angle, and the mating protrusion 131 is located within the included angle formed by the first abutting wall and the second abutting wall and is close to the connecting area. When the manual knob 200 is turned clockwise, the second abutting wall can press the mating protrusion 131, causing the sliding member to move from the first position to the second position; when the manual knob 200 is turned counterclockwise, the first abutting wall can press the mating protrusion 131, causing the sliding member to move from the first position to the second position. Based on this, the power separation of the first transmission member 120 and the second transmission member 130 can be realized during the locking or unlocking process, thereby allowing for easy manual locking or unlocking. It should be noted here that one of the clockwise or counterclockwise rotation of the manual knob 200 is the locking process, and the other is the unlocking process.

[0055] In order for the slider to move from the second position to the first position, the lock may further include a first resilient reset member 410, such as Figure 3 and Figure 4As shown, the first elastic reset member 410 connects the lock cylinder 300 and the sliding member, and the first elastic reset member 410 can deform as the sliding member rotates with the manual knob 200. The first elastic reset member 410 is used to drive the sliding member from the second position to the first position. Based on this, when the toggle protrusion 210 of the manual knob 200 releases its action on the mating protrusion 131, the sliding member moves under the elastic force of the first elastic reset member 410 and returns from the second position to the first position, and engages with the connecting groove 121, thereby realizing the power connection between the first transmission member 120 and the second transmission member 130 again. It should be noted that after locking or unlocking by the manual knob 200, the manual knob 200 can be reset, thereby releasing its action on the mating protrusion 131. In this way, the sliding member can also be reset under the elastic force of the first elastic reset member 410.

[0056] For example, the first elastic reset member 410 can be a spring, including tension springs, compression springs, torsion springs, etc. Of course, other methods can also be used to reset the sliding member, such as: using a linear motor drive, a button press drive, a wrench pull drive, a cam drive, etc., and the specific drive method is not limited. Alternatively, the first elastic reset member 410 can be omitted, and reset can be performed manually.

[0057] To achieve the reset of the manual knob 200, the lock may also include a second resilient reset element 420, such as... Figure 3 and Figure 4 As shown, the manual knob 200 rotatably engages with the lock cylinder 300. A second elastic reset member 420 connects the lock cylinder 300 and the manual knob 200. This second elastic reset member 420 can deform as the manual knob 200 rotates, driving the manual knob 200 to reset. Therefore, when the manual knob 200 is released, the elastic force of the second elastic reset member 420 causes the manual knob 200 to rotate a certain angle relative to the lock cylinder 300, thus achieving the reset of the manual knob 200.

[0058] Considering that the direction of rotation of the manual knob 200 may be opposite during the locking and unlocking processes, in order to enable the manual knob 200 to be reset during the locking and unlocking processes respectively, two sets of second elastic reset members 420 can be set to reset the manual knob 200 during the locking and unlocking processes respectively.

[0059] For example, the second elastic reset member 420 can be a spring, including tension springs, compression springs, torsion springs, etc. Of course, other methods can also be used to reset the sliding member, such as: using a linear motor drive, using a button press drive, using a wrench pull drive, using a cam drive, etc., and the specific drive method is not limited.

[0060] It should be noted that, in order to prevent the electric drive mechanism 100 from hindering the rotation of the lock cylinder 300, the separation action of the first transmission member 120 and the second transmission member 130 can be made to occur before the rotation action of the lock cylinder 300. Based on this, when turning the manual knob 200, the protrusion 210 is first used to act on the mating protrusion 131 to drive the sliding member to slide out of the connecting groove 121. During this process, the manual knob 200 does not drive the lock cylinder 300 to rotate, so that the power separation is achieved first and the lock cylinder 300 is rotated later, thereby avoiding the electric drive mechanism 100 from hindering the rotation of the lock cylinder 300.

[0061] In some embodiments, the lock cylinder 300 may be provided with a limiting groove, and correspondingly, the manual knob 200 may be provided with a limiting block. The limiting member is slidably disposed in the limiting groove, and the second elastic reset member 420 may connect the limiting block and the limiting groove. Specifically, along the rotation direction of the manual knob 200, the two ends of the limiting groove are respectively provided with a first limiting surface and a second limiting surface. One of the second elastic reset members 420 is connected between the first limiting surface and one side of the limiting block, and the other second elastic reset member 420 is connected between the second limiting surface and the other side of the limiting block. Based on this, during the process of the manual knob 200 rotating and the sliding member sliding out of the connecting groove 121 by the action of the toggle protrusion 210 and the engagement protrusion 131, one of the second elastic reset members 420 is compressed. As the manual knob 200 continues to rotate, when a certain degree is reached, the limiting block will press the first limiting surface or the second limiting surface through the second elastic reset member 420, thereby causing the lock cylinder 300 to start rotating with the manual knob 200, so as to realize locking or unlocking.

[0062] Of course, other implementation methods can also be adopted. Specifically, the second elastic reset member 420 is independent of the limiting block and the limiting groove. In this case, when the limiting block slides in the limiting groove and touches the first limiting surface or the second limiting surface, the lock cylinder 300 can be rotated by the manual knob 200.

[0063] When the manual knob 200 is released, the second elastic reset member 420 will cause the manual knob 200 to rotate relative to the lock cylinder 300, thereby resetting the manual knob 200.

[0064] refer to Figures 5 to 10 In order to achieve power separation between the first transmission member 120 and the second transmission member 130, in some embodiments, the manual knob 200 may include a first sub-knob 201, which is movably engaged with the lock cylinder 300, and the rotation of the first sub-knob 201 can drive the lock cylinder 300 to rotate. The sliding member is engaged with the first sub-knob 201, and the movement of the first sub-knob 201 can drive the sliding member to move from a first position to a second position.

[0065] When the lock cylinder 300 needs to be manually turned, the user can apply force to the first sub-knob 201, causing the first sub-knob 201 to move relative to the lock cylinder 300. During the movement, the first sub-knob 201 drives the sliding member to slide out of the connecting groove 121, that is, drives the sliding member to move from the first position to the second position, thereby realizing the power separation between the first transmission member 120 and the second transmission member 130. Then, as the manual knob 200 is turned, the locking rotation is driven without being hindered by the electric drive mechanism 100.

[0066] For example, the first sub-knob 201 can directly press the slider by one side, or the first sub-knob 201 can be provided with a guide hole, and the slider can extend at least partially into the guide hole to achieve engagement. Of course, there can be other methods, which are not specifically limited here.

[0067] Based on the above settings, the sliding member can be moved by moving at least part of the structure of the manual knob 200, thereby achieving power separation of the electric drive mechanism 100. Furthermore, the manual knob 200 can also open and close the lock cylinder 300, achieving a dual-purpose effect.

[0068] In addition, when the first sub-knob 201 releases its effect on the slider, the slider can be reset. The slider can be elastically reset by the first elastic reset member 410. It can also be driven by a linear motor, by pressing a button, by pulling a wrench, by a cam, manually, etc. The specific driving method is not limited.

[0069] refer to Figure 9 and Figure 10 In other embodiments, the manual knob 200 may further include a second sub-knob 202 and a connecting rod 203. The second sub-knob 202 is movably engaged with the lock cylinder 300 and includes a push protrusion 2021. The connecting rod 203 is rotatably mounted on the lock cylinder 300, with its first end rotatably connected to a sliding member, and its second end opposite to the push protrusion 2021. Therefore, when the second sub-knob 202 moves, it can drive the push protrusion 2021 to rotate the second end of the connecting rod 203, and the rotation of the first end of the connecting rod 203 will cause the sliding member to move from a first position to a second position.

[0070] When the lock cylinder 300 needs to be manually turned, the user can apply force to the second sub-knob 202, causing the second sub-knob 202 to move relative to the lock cylinder 300. This allows the power to push the protrusion 2021 to be transmitted to the sliding member through the connecting rod 203, causing the sliding member to slide out of the connection. That is, it drives the sliding member to move from the first position to the second position, thereby achieving power separation between the first transmission member 120 and the second transmission member 130. Then, as the manual knob 200 is turned, the locking rotation is driven without being hindered by the electric drive mechanism 100.

[0071] In some embodiments, the slider may include a rotatable connecting protrusion 132. Correspondingly, the first end of the connecting rod 203 may be provided with a slotted hole 2031. The rotatable connecting protrusion 132 extends into the slotted hole 2031 and rotates and slides with the slotted hole 2031. Based on this, as the connecting rod 203 rotates relative to the lock cylinder 300 under the pushing action of the pushing protrusion 2021, the connecting rod 203 acts as a lever. The rotatable connecting protrusion 132 can be squeezed through the hole wall of the slotted hole 2031, so that the slider moves towards the second position. At the same time, the rotatable connecting protrusion 132 can also float in the slotted hole 2031 to avoid motion interference.

[0072] To facilitate the user in applying force to the manual knob 200, such as by squeezing the manual knob 200, the manual knob 200 may also include a first sub-knob 201 and a second sub-knob 202, which can move towards or away from the lock cylinder 300. When the first knob and the second sub-knob 202 move towards each other, the first sub-knob 201 can press the sliding member towards the second position. At the same time, the second sub-knob 202 can press the sliding member towards the second position through the connecting rod 203, thereby enabling the sliding member to move from the first position to the second position.

[0073] Based on the above configuration, the user can easily grip the manual knob 200. By pinching the first sub-knob 201 and the second sub-knob 202 from both sides, the sliding component can be disengaged from the connecting groove 121, achieving power separation. Then, a turning force can be applied to rotate the lock cylinder 300 through the manual knob 200, thereby locking or unlocking. Compared to using only the first sub-knob 201 or the second sub-knob 202, this method can apply force from two directions, making it easier for the user to grip and operate. At the same time, it can also prevent the first sub-knob 201 or the second sub-knob 202 from moving excessively.

[0074] To facilitate the separate reset of the first sub-knob 201 and the second sub-knob 202, the manual knob 200 may also include a third elastic reset element 204, such as... Figure 8As shown, the third elastic reset member 204 is disposed between the first sub-knob 201 and the second sub-knob 202. The third elastic reset member 204 is used to drive the first sub-knob 201 and the second sub-knob 202 away from each other. Based on this, after the user locks or unlocks and releases the manual knob 200, the first sub-knob 201 and the second sub-knob 202 move away from each other under the elastic force of the third elastic reset member 204, thereby facilitating their reset so that they can be gripped and pressed by the user next time.

[0075] For example, the third elastic reset member 204 can be an elastic component such as a compression spring, a spring sheet, or a rubber block, as long as it can separate the first sub-knob 201 from the second sub-knob 202. The specific method is not limited.

[0076] In other embodiments, the third elastic reset member 204 may not be provided, and the separation of the first sub-knob 201 and the second sub-knob 202 may be achieved by manual tossing.

[0077] In addition, when the first sub-knob 201 and the second sub-knob 202 are reset and the action on the slider is released, the slider can be reset. The slider can be elastically reset by the first elastic reset member 410. It can also be driven by a linear motor, by pressing a button, by pulling a wrench, by a cam, etc. The specific driving method is not limited.

[0078] refer to Figure 8 In some embodiments, the manual knob 200 may further include a third sub-knob 205, which covers the end of the lock cylinder 300 and is connected to the lock cylinder 300. Rotation of the third sub-knob 205 can drive the lock cylinder 300 to rotate, while the first sub-knob 201 and the second sub-knob 202 are movably disposed on the third sub-knob 205. By providing the third sub-knob 205, the lock cylinder 300 can be shielded, thereby effectively preventing external dust, impurities, water, etc. from entering the interior of the lock cylinder 300 and causing damage to the lock cylinder 300, and also improving the appearance and assemblability of the lock; in addition, the third sub-knob 205 can also serve to support and install the first sub-knob 201 and the second sub-knob 202.

[0079] To improve the smoothness of the movement of the first sub-knob 201 relative to the third sub-knob 205, a U-shaped equalizer 206 can be provided inside the first sub-knob 201, such as... Figure 8As shown, the bottom of the U-shaped equalizer 206 is rotatably mounted on the third sub-knob 205, and the top of the U-shaped equalizer 206 is connected to the first sub-knob 201 and can swing as the first sub-knob 201 moves. The first end of the U-shaped equalizer 206 is located at the first end of the first sub-knob 201, and the second end of the U-shaped equalizer 206 is located at the second end of the first sub-knob 201. This arrangement improves the balance of both ends of the first sub-knob 201, making the forces on both ends of the first sub-knob 201 more balanced. This effectively alleviates the problem of the other end of the first sub-knob 201 tilting when one end is being operated, thereby improving the smoothness of the movement of the first sub-knob 201 relative to the third sub-knob 205.

[0080] Similarly, to improve the smoothness of the movement of the second sub-knob 202 relative to the third sub-knob 205, a U-shaped equalizer 206 can also be provided inside the second sub-knob 202. The bottom of the U-shaped equalizer 206 is rotatably disposed on the third sub-knob 205, and the top of the U-shaped equalizer 206 is connected to the second sub-knob 202 and can swing with the movement of the second sub-knob 202. The first end of the U-shaped equalizer 206 is located at the first end of the second sub-knob 202, and the second end of the U-shaped equalizer 206 is located at the second end of the second sub-knob 202. This arrangement improves the balance of the two ends of the second sub-knob 202, making the force on both ends of the second sub-knob 202 more balanced. This effectively alleviates the problem of the other end of the second sub-knob 202 tilting when one end is being operated, thereby improving the smoothness of the movement of the second sub-knob 202 relative to the third sub-knob 205.

[0081] To determine the rotation status of the lock cylinder 300, the lock may also include an angle detection mechanism 500, such as... Figure 1 and Figure 5 As shown, the angle detection mechanism 500 is connected to the lock cylinder 300 and can rotate with the lock cylinder 300 to obtain the rotation angle of the lock cylinder 300.

[0082] For example, the angle detection mechanism 500 may include an angle sensor 510 and a third gear 520. The input end of the angle sensor 510 is connected to the third gear 520 for transmission. Correspondingly, the lock cylinder 300 may also include a second gear 302, which meshes with the third gear 520. Thus, during the rotation of the lock cylinder 300, the second gear 302 will rotate, driving the third gear 520 to rotate synchronously. This allows the input end of the angle sensor 510 to rotate through the third gear 520, thereby determining the rotation angle of the lock cylinder 300. It should be noted that the specific structure and working principle of the angle sensor 510 can be found in related technologies and will not be elaborated here.

[0083] Furthermore, the lock may also include a controller, which is electrically connected to the angle detection mechanism 500 and the electric drive mechanism 100 respectively. In this way, when the angle detected by the angle detection mechanism 500 reaches the preset angle threshold, the controller controls the electric drive mechanism 100 to stop. At this time, it is determined that the lock cylinder 300 has rotated to the locked or unlocked position, thereby determining the state of the lock.

[0084] In addition, the lock may also include a circuit board 600, in which electrical components such as the controller and the angle detection mechanism 500 can be electrically connected to the circuit board 600.

[0085] In summary, the lock in this embodiment can disconnect the transmission connection between the electric drive mechanism 100 and the lock cylinder 300 when the electric drive mechanism 100 malfunctions, so that the electric drive mechanism 100 will not obstruct the movement of the lock cylinder 300. Thus, when the manual knob 200 drives the lock cylinder 300, there is no transmission resistance caused by the electric drive mechanism 100, which allows the user to lock or unlock more easily and improves the user experience.

As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these modifications are within the protection scope of the present invention.
