Description

Technical Field

[0001] This application relates to the field of Type-C cylindrical lock technology, and specifically to a Type-C cylindrical lock. Background Technology

[0002] With the continuous development of science and technology, people have increasingly higher demands for the intelligence and security of cylindrical locks. Especially for products required by banks, extremely high security and reliability are needed, but existing electronic cylindrical locks cannot record the lock's status. Utility Model Content

[0003] In view of the above problems, this application provides a Type-C cylindrical lock that can transmit the status information of the Type-C cylindrical lock to an electronic key for recording via a Type-C interface.

[0004] This application provides a Type-C cylindrical lock, including:

[0005] The lock body is cylindrical with a hollow interior and a limit groove on the inner wall.

[0006] A lock cylinder, located inside the lock body, includes a Type-C interface, a main control board, a drive assembly, and a bolt. The Type-C interface is exposed outside the lock body and can be connected to the electronic key. The main control board is electrically connected to both the Type-C interface and the drive assembly.

[0007] The main control board is used to control the drive assembly to limit and lock the bolt, so that the bolt extends into the limiting groove; the main control board is also used to control the drive assembly to release the limiting lock on the bolt, and when the lock cylinder is unlocked and rotated, the inner wall of the lock body squeezes the bolt to make it disengage from the limiting groove.

[0008] The Type-C cylindrical lock of this application embodiment has a Type-C interface on the lock cylinder. When the Type-C interface is connected to a compatible electronic key, the electronic key authorizes the Type-C cylindrical lock, and the drive component releases the locking mechanism of the bolt. At this time, the lock cylinder can rotate relative to the lock body. When the lock cylinder rotates to the unlocked or locked position, the bolt will extend into the limiting groove. If the connection between the Type-C interface and the electronic key is disconnected at this time, ending the authorization of the electronic key, the drive component can lock the bolt, preventing the lock cylinder from rotating relative to the lock body, thereby fixing the lock cylinder in the unlocked or locked position, and thus maintaining the Type-C cylindrical lock in the unlocked or locked state. In addition, due to the connection between the Type-C interface and the electronic key, the status information of the Type-C cylindrical lock can be transmitted to the electronic key for recording through the Type-C interface.

[0009] In some embodiments, the lock cylinder further includes a lock cylinder body and a first elastic element. The lock cylinder body is rotatably connected to the lock body, and the type-c interface is disposed on the lock cylinder body. The bolt is movably disposed on the lock cylinder body, and the bolt has a bolt locking position and a bolt unlocking position.

[0010] In the locked position, the bolt extends out of the lock cylinder body and into the limiting groove; in the unlocked position, the bolt retracts into the lock cylinder body to disengage from the limiting groove.

[0011] The drive assembly is disposed within the lock cylinder body;

[0012] The first elastic element is elastically connected between the lock cylinder body and the bolt, and is used to drive the bolt to move from the bolt unlock position to the bolt lock position.

[0013] In the above scheme, the rotation of the lock cylinder relative to the lock body is controlled by moving the bolt between the bolt locking position and the bolt unlocking position. Specifically, when the bolt moves to the bolt locking position, it prevents the rotation of the lock cylinder relative to the lock body, temporarily fixing the lock cylinder in the unlocked or locked position. At the same time, the bolt can be limited and locked by the drive component to lock the bolt in the bolt locking position. When the lock cylinder is rotating, the drive component can release the bolt limiting lock, allowing the bolt to move to the bolt unlocking position to ensure the rotation of the lock cylinder relative to the lock body. In addition, by elastically connecting the first elastic element between the lock cylinder body and the bolt, when the lock cylinder body rotates to the unlocked or locked position, the elastic force of the first elastic element drives the bolt to move from the bolt unlocking position to the bolt locking position, fixing the lock cylinder body in the unlocked or locked position.

[0014] In some embodiments, the lock cylinder body has an unlocked position and a locked position;

[0015] The lock body is provided with a first limiting part and a second limiting part, and both the first limiting part and the second limiting part are provided with the limiting groove;

[0016] In the unlocked position, the latch moves to the latch locked position and engages with the limiting groove of the first limiting part; in the locked position, the latch moves to the latch locked position and engages with the limiting groove of the second limiting part.

[0017] In the above scheme, when the lock cylinder body rotates to the unlocked position, the lock cylinder body is prevented from continuing to rotate relative to the lock body by the engagement of the bolt with the limiting groove of the first limiting part and the limiting lock of the bolt by the drive component after the electronic key authorization ends, thus fixing the lock cylinder body in the unlocked position. When the lock cylinder body rotates to the locked position, the lock cylinder body is prevented from continuing to rotate relative to the lock body by the engagement of the bolt with the limiting groove of the second limiting part and the limiting lock of the bolt by the drive component after the electronic key authorization ends, thus fixing the lock cylinder body in the locked position.

[0018] In some embodiments, the lock body is further provided with a rotating hole; the lock cylinder body is rotatably installed in the rotating hole;

[0019] The first limiting part and the second limiting part are provided on the hole wall of the rotating hole;

[0020] The lock cylinder body is provided with a limiting hole and an assembly hole. The limiting hole communicates with the rotating hole through the assembly hole. The lock tongue is slidably connected to the assembly hole in a direction intersecting the axial direction of the lock cylinder. The drive assembly is installed in the limiting hole.

[0021] In the above solution, the lock cylinder body is rotatably installed in the rotating hole of the lock body, and the first and second limiting parts are provided on the hole wall of the rotating hole, so that when the lock cylinder body rotates to the unlocked or locked position, the bolt installed on the lock cylinder body can engage with the first or second limiting part. Furthermore, the bolt is slidably connected to the mounting hole of the lock cylinder body in a direction intersecting the axial direction of the lock cylinder body, and the drive assembly is installed in the limiting hole of the lock cylinder body, thus achieving the installation of the bolt and drive assembly on the lock cylinder body.

[0022] In some embodiments, the extending direction of the limiting hole is parallel to the axial direction of the lock cylinder body; the extending direction of the assembly hole is perpendicular to the extending direction of the limiting hole, thus forming the lock cylinder body.

[0023] In the above scheme, since the extension direction of the limiting hole is parallel to the axial direction of the lock cylinder body and the extension direction of the mounting hole is perpendicular to the extension direction of the limiting hole, the extension direction of the mounting hole can be made parallel to the radial direction of the lock cylinder body. In this way, the direction of the force of the bolt against the lock body can be parallel to the radial direction of the lock cylinder body. At this time, the bolt can more stably fix the lock cylinder body in the unlocked or locked position.

[0024] In some embodiments, the drive assembly includes a solenoid drive, an iron core, and a second elastic element; the iron core has a first position for limiting and locking the latch and a second position for releasing the limiting and locking of the latch;

[0025] The solenoid driver is electrically connected to the type-c interface, and the solenoid driver is used to drive the iron core to move from the first position to the second position when the electronic key is connected to the type-c interface;

[0026] The second elastic element is elastically connected between the iron core and the solenoid drive, and the second elastic element is used to drive the iron core to move from the second position to the first position when the type-c interface is disconnected from the electronic key.

[0027] In the above scheme, when the lock cylinder body is moving from the unlocked position to the locked position, or from the locked position to the unlocked position, the solenoid drive can move the iron core from the first position to the second position to release the locking of the bolt, allowing the bolt to move to the unlocked position and ensuring the rotation of the lock cylinder body relative to the lock body. When the lock cylinder body rotates to the unlocked or locked position and the electronic key authorization ends, the second elastic element can drive the iron core from the second position to the first position to lock the bolt in the locked position, fixing the lock cylinder body in the unlocked or locked position.

[0028] In some embodiments, the type-c cylindrical lock further includes a detection component, a first sensor, and a second sensor. The detection component is installed on the lock cylinder body and is communicatively connected to the type-c interface. The first sensor and the second sensor are installed on the lock body.

[0029] In the unlocked position, the detection component can detect the first sensor; in the locked position, the detection component can detect the second sensor.

[0030] In the above scheme, when the lock cylinder body rotates to the unlocked position, the detection component can detect the first sensor to obtain the unlocked status information of the Type-C cylindrical lock; when the lock cylinder body rotates to the locked position, the detection component can detect the second sensor to obtain the locked status information of the Type-C cylindrical lock. By sensing different sensors, the detection component obtains the corresponding status information of the Type-C cylindrical lock. Simultaneously, through the communication connection between the detection component and the Type-C interface, the obtained status information can be transmitted to the electronic key for recording via the Type-C interface.

[0031] In some embodiments, the cylindrical lock further includes a locking assembly, a baffle, and a baffle mounting assembly. The locking assembly is mounted on the lock body and can cooperate with the lock body to install the type-c cylindrical lock on the door panel of the device to be locked.

[0032] The baffle mounting assembly is disposed on the lock cylinder, the baffle is mounted on the baffle mounting assembly, and can rotate synchronously with the lock cylinder through the baffle mounting assembly;

[0033] In the locked position, the baffle can engage with the housing of the device to be locked; in the unlocked position, the baffle is released from engagement with the housing of the device to be locked.

[0034] In the above solution, a locking component is installed on the lock body to facilitate the installation of the Type-C cylindrical lock onto the door panel of the device to be locked. Simultaneously, a retaining plate is installed on the lock cylinder via a retaining plate mounting component, allowing the retaining plate to move via the lock cylinder. When the retaining plate engages with the housing of the device to be locked, it locks the door panel of the device to the housing; when the retaining plate disengages from the housing, the door panel of the device to be locked unlocks from the housing, allowing the door panel to be opened.

[0035] In some embodiments, the baffle mounting assembly includes a connecting plate, a flat shaft, and a fixing member. The connecting plate is mounted on the lock cylinder, and a rotation limiting structure is provided between the connecting plate and the lock body. The rotation limiting structure is used to limit the rotation angle of the connecting plate relative to the lock body.

[0036] The flat shaft is mounted on the connecting plate and protrudes from the lock body, and the flat shaft is adapted to be inserted into the baffle plate;

[0037] The fastener is installed on the flat shaft to fix the baffle between the fastener and the connecting plate.

[0038] In the above solution, the baffle mounting assembly consists of a connecting plate, a flat shaft, and a fixing component. The connecting plate enables the mounting connection between the baffle mounting assembly and the lock cylinder. Simultaneously, the rotation angle of the connecting plate and the lock cylinder relative to the lock body is limited by the rotation-limiting structure between the connecting plate and the lock body. Furthermore, the installation of the baffle is achieved through the cooperation between the connecting plate, the flat shaft, and the fixing component.

[0039] In some embodiments, the lock body includes a first locking segment and a second locking segment connected to the first locking segment, wherein the cross-sectional area of ​​the first locking segment is larger than the cross-sectional area of ​​the second locking segment, and a bearing surface is formed at the position where the first locking segment and the second locking segment are connected;

[0040] The locking assembly includes a locking washer and a locking nut. The locking washer is sleeved on the second locking segment. The locking nut is threadedly connected to the second locking segment and is located on the side of the locking washer facing away from the first locking segment.

[0041] A clamping gap suitable for assembling with a door panel of a lock-to-be-installed device can be formed between the abutting surface and the locking washer.

[0042] In the above solution, a support surface is formed on the outer wall of the lock body. Through the cooperation of the support surface with the locking washer and the locking nut, the door panel of the device to be locked can be clamped in the clamping gap, thereby realizing the installation and connection of the type-c cylindrical lock and the device to be locked.

In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0062] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0063] According to some embodiments of this application, refer to Figures 1-6This application provides a Type-C cylindrical lock, including a lock body 1 and a lock cylinder 2. The lock body 1 is cylindrical and hollow inside. The inner wall of the lock body 1 has a limiting groove (see...). Figure 3 and Figure 3 The first limiting part 11 and the second limiting part 12 in the middle).

[0064] The lock cylinder 2 is located inside the lock body 1 and includes a Type-C interface 214, a main control board (not shown), a drive assembly 23, and a bolt 22. The Type-C interface 214 protrudes from the lock body 1 and can be connected to the electronic key. The main control board is electrically connected to both the Type-C interface 214 and the drive assembly 23. The Type-C interface 214 is a male Type-C connector.

[0065] The main control board is used to control the drive assembly 23 to limit and lock the bolt 22, so that the bolt 22 extends into the limiting groove. The main control board is also used to control the drive assembly 23 to release the limiting lock on the bolt 22. When the lock cylinder 2 is unlocked and rotated, the inner wall of the lock body 1 presses the bolt 22 to disengage it from the limiting groove.

[0066] In this embodiment of the Type-C cylindrical lock, a Type-C interface 214 is provided in the lock cylinder 2. When the Type-C interface 214 is connected to the compatible electronic key, the electronic key authorizes the Type-C cylindrical lock, and the drive assembly 23 releases the limiting lock on the bolt 22. At this time, the lock cylinder 2 can rotate relative to the lock body 1. When the lock cylinder 2 rotates to the unlocked or locked position, the bolt 22 will extend into the limiting groove. If the connection between the Type-C interface 214 and the electronic key is disconnected at this time, ending the authorization of the electronic key, the drive assembly 23 can limit the locking of the bolt 22, preventing the lock cylinder 2 from rotating relative to the lock body 1, thereby fixing the lock cylinder 2 in the unlocked or locked position, and thus maintaining the Type-C cylindrical lock in the unlocked or locked state. In addition, due to the connection between the Type-C interface 214 and the electronic key, the status information of the Type-C cylindrical lock can be transmitted to the electronic key for recording through the Type-C interface 214.

[0067] According to some embodiments of this application, refer to Figures 3-4 The lock cylinder 2 also includes a lock cylinder body 21. The lock cylinder body 21 is rotatably mounted on the lock body 1, and the lock cylinder body 21 has an unlocked position and a locked position. A type-C interface 214 is provided on the lock cylinder body 21. The type-C interface 214 is used to connect a compatible electronic key, and can drive the lock cylinder body 21 to rotate relative to the lock body 1 under the action of the electronic key, so that the lock cylinder body 21 reciprocates between the unlocked position and the locked position.

[0068] The bolt 22 is movably mounted on the lock cylinder body 21, and the bolt 22 has a bolt locking position (see reference). Figure 3 The position of the latch 22 shown) and the unlocked position of the latch (refer to) Figure 4 (The position of the bolt 22 is shown). In the unlocked or locked position, refer to... Figure 3 When the lock cylinder body 21 is in the unlocked or locked position, the bolt 22 extends out of the lock cylinder body 21 and into the limiting groove, causing the bolt 22 to move to the bolt locking position, preventing the lock cylinder body 21 from rotating relative to the lock body 1. When the lock cylinder body 21 moves between the unlocked and locked positions, refer to... Figure 4 The bolt 22 retracts into the lock cylinder body 21 to disengage from the limiting groove, allowing the bolt 22 to move to the bolt unlock position, thus enabling the lock cylinder body 21 to rotate relative to the lock body 1.

[0069] The drive assembly 23 is disposed within the lock cylinder body 21. When an electronic key is connected to the Type-C interface 214, the drive assembly 23 can release the limiting lock on the bolt 22, allowing the bolt 22 to retract into the lock cylinder body 21 and move to the bolt unlock position. The drive assembly 23 can also limit the bolt 22 when the connection to the electronic key is disconnected from the Type-C interface 214, locking the bolt 22 in the bolt locked position.

[0070] In the above scheme, the rotation of the lock cylinder 2 relative to the lock body 1 is controlled by moving the bolt 22 between the bolt locking position and the bolt unlocking position. Specifically, when the lock cylinder 2 rotates to the unlocking position or the locked position, the bolt 22 can be moved to the bolt locking position to prevent the rotation of the lock cylinder 2 relative to the lock body 1, temporarily fixing the lock cylinder 2 in the unlocking or locked position. At the same time, the bolt 22 can be limited and locked by the drive assembly 23 to lock the bolt 22 in the bolt locking position. When the lock cylinder 2 is in the process of moving from the unlocking position to the locked position, or from the locked position to the unlocking position, the drive assembly 23 can release the limited locking of the bolt 22, thereby allowing the bolt 22 to move to the bolt unlocking position to avoid obstructing the rotation of the lock cylinder 2 and to ensure the rotation of the lock cylinder 2 relative to the lock body 1.

[0071] According to some embodiments of this application, refer to Figures 3-4 The lock cylinder 2 also includes a first elastic element 24, which is elastically connected between the lock cylinder body 21 and the bolt 22, and is used to drive the bolt 22 to move from the bolt unlock position to the bolt lock position.

[0072] In the above solution, by elastically connecting the first elastic element 24 between the lock cylinder body 21 and the bolt 22, when the lock cylinder body 21 is rotated to the unlock position or the locked position, the bolt 22 is driven to move from the unlock position to the locked position by the elastic force of the first elastic element 24, thereby fixing the lock cylinder body 21 in the unlock position or the locked position.

[0073] According to some embodiments of this application, refer to Figures 3-5 The lock body 1 is provided with a first limiting part 11 and a second limiting part 12, and both the first limiting part 11 and the second limiting part 12 are provided with the limiting groove.

[0074] In the unlocked position, the latch 22 moves to the latch locked position and engages with the limiting groove of the first limiting part 11. In the locked position, the latch 22 moves to the latch locked position and engages with the limiting groove of the second limiting part 12.

[0075] In the above scheme, when the lock cylinder body 21 rotates to the unlocked position, the lock cylinder body 21 is prevented from continuing to rotate relative to the lock body 1 by the engagement of the bolt 22 with the limiting groove of the first limiting part 11 and the limiting lock of the bolt 22 by the drive component 23 after the electronic key authorization ends, thereby fixing the lock cylinder 21 in the unlocked position. When the lock cylinder body 21 rotates to the locked position, the lock cylinder body 21 is prevented from continuing to rotate relative to the lock body 1 by the engagement of the bolt 22 with the limiting groove of the second limiting part 12 and the release of the limiting lock of the bolt 22 by the drive component 23 after the electronic key authorization ends, thereby fixing the lock cylinder body 21 in the locked position.

[0076] According to some embodiments of this application, refer to Figures 3-4 The lock body 1 is also provided with a rotating hole 13. The lock cylinder body 21 is rotatably installed in the rotating hole 13.

[0077] The first limiting part 11 and the second limiting part 12 are provided on the wall of the rotating hole 13.

[0078] The lock cylinder body 21 is provided with a limiting hole 211 and an assembly hole 212. The limiting hole 211 is connected to the rotating hole 13 through the assembly hole 212. The lock tongue 22 is slidably connected to the assembly hole 212 in a direction intersecting with the axial direction of the lock cylinder 2. The drive assembly 23 is installed in the limiting hole 211.

[0079] The axial direction of lock cylinder 2 is parallel to the extension direction of the rotation axis of lock cylinder 2.

[0080] In the above solution, the lock cylinder body 21 is rotatably installed in the rotation hole 13 of the lock body 1, and the first limiting part 11 and the second limiting part 12 are provided on the hole wall of the rotation hole 13, so that when the lock cylinder body 21 is rotated to the unlocked position or the locked position, the bolt 22 installed on the lock cylinder body 21 can engage with the first limiting part 11 or the second limiting part 12. In addition, the bolt 22 is slidably connected to the mounting hole 212 of the lock cylinder body 21 in a direction intersecting with the axial direction of the lock cylinder body 21, and the drive assembly 23 is installed in the limiting hole 211 of the lock cylinder body 21, thereby realizing the installation of the bolt 22 and the drive assembly 23 on the lock cylinder body 21.

[0081] According to some embodiments of this application, refer to Figures 3-4 The assembly hole 212 includes a first hole segment 2121 and a second hole segment 2122. The second hole segment 2122 connects the first hole segment 2121 and the limiting hole 211. The diameter of the first hole segment 2121 is larger than the diameter of the second hole segment 2122. A first step surface is formed at the position where the first hole segment 2121 and the second hole segment 2122 connect.

[0082] The latch 22 includes a first latch segment 221 and a second latch segment 222 connected to the first latch segment 221. The cross-sectional area of ​​the first latch segment 221 is larger than the cross-sectional area of ​​the second latch segment 222. A second stepped surface is formed at the position where the first latch segment 221 and the second latch segment 222 are connected.

[0083] The second locking tongue segment 222 passes through the first elastic member 24 and is slidably connected to the second hole segment 2122. The first elastic member 24 is housed in the first hole segment 2121 and is elastically supported between the first step surface and the second step surface.

[0084] In the above scheme, the structure of the mounting hole 212 and the structure of the latch 22 are refined. The second latch segment 222 of the latch 22 is slidably connected to the second hole segment 2122 through the first elastic member 24, and the first elastic member 24 is elastically supported between the first step surface and the second step surface, so as to realize the installation of the latch 22 and the first elastic member 24 on the lock cylinder body 21.

[0085] According to some embodiments of this application, refer to Figures 1-6 The extending direction of the limiting hole 211 is parallel to the axial direction of the lock cylinder body 21. The extending direction of the assembly hole 212 is perpendicular to the extending direction of the limiting hole 211, thus forming the lock cylinder body 21.

[0086] Furthermore, the axial direction of the lock cylinder body 21 is parallel to the axial direction of the lock cylinder 2.

[0087] In the above scheme, since the extension direction of the limiting hole 211 is parallel to the axial direction of the lock cylinder body 21 and the extension direction of the mounting hole 212 is perpendicular to the extension direction of the limiting hole 211, the extension direction of the mounting hole 212 can be parallel to the radial direction of the lock cylinder body 21. In this way, the direction of the force of the bolt 22 against the lock body 1 can be parallel to the radial direction of the lock cylinder body 21. At this time, the bolt 22 can more stably fix the lock cylinder body 21 in the unlocked or locked position.

[0088] According to some embodiments of this application, refer to Figures 3-4 The drive assembly 23 includes a solenoid drive element 231, an iron core 232, and a second elastic element 233. The iron core 232 has a first position for limiting and locking the locking tongue 22 (see reference). Figure 3 The position of the iron core 232 shown) and the second position (refer to) where the locking bolt 22 is released from its limiting lock. Figure 4 (The position of the iron core 232 is shown).

[0089] The solenoid drive 231 is electrically connected to the type-c interface 214. The solenoid drive 231 is used to drive the iron core 232 from the first position to the second position when the electronic key is connected to the type-c interface 214.

[0090] The second elastic element 233 is elastically connected between the iron core 232 and the solenoid drive element 231. The second elastic element 233 is used to drive the iron core 232 to move from the second position to the first position when the type-c interface 214 is disconnected from the electronic key.

[0091] In the above scheme, when the lock cylinder body 21 is in the process of moving from the unlocked position to the locked position, or in the process of moving from the locked position to the unlocked position, refer to Figure 4 The solenoid drive 231 can drive the iron core 232 from the first position to the second position to release the limiting lock on the bolt 22, allowing the bolt 22 to move to the unlocked position and ensuring the rotation of the lock cylinder body 21 relative to the lock body 1. When the lock cylinder body 21 rotates to the unlocked or locked position and the electronic key authorization ends, refer to... Figure 3 The second elastic element 233 can drive the iron core 232 to move from the second position to the first position, so as to limit and lock the bolt 22 in the bolt locking position and fix the lock cylinder body 21 in the unlocked position or the locked position.

When the lock cylinder body 21 rotates to the locked position, the detection component 3 can detect the second sensor 5 to obtain the locked status information of the Type-C cylindrical lock. By sensing different sensors, the detection component 3 obtains the corresponding status information of the Type-C cylindrical lock. At the same time, through the communication connection between the detection component 3 and the Type-C interface 214, the obtained status information can be transmitted to the electronic key for recording via the Type-C interface 214.
