Technical Field
[0001] This invention relates to the field of lock technology, specifically to a lock cylinder, a door lock, and a security door. Background Technology
[0002] A door lock is a device used to protect property, premises, or information security. To prevent the lock from becoming unusable due to a depleted battery, most smart locks in current technology are equipped with an emergency charging port and a key-operated lock cylinder. However, this results in a large number of openings on the lock surface, significantly impacting the lock's waterproof and dustproof performance and also detracting from its aesthetics. Summary of the Invention
[0003] In view of this, the present invention provides a lock cylinder, a door lock, and a security door to solve the problems of door locks in the prior art.
[0004] In a first aspect, the present invention provides a lock cylinder, comprising:
[0005] The lock cylinder has a keyhole at one end and a lever at the other end.
[0006] The lock case is arranged around the outside of the lock cylinder;
[0007] The charging socket is located inside the keyhole and is suitable for sliding along the depth direction of the keyhole. It is suitable for connecting the charging circuit of the door lock. The charging socket has a charging position and a clearance position. In the charging position, the charging socket is located at the end of the keyhole away from the lever. In the clearance position, the charging socket is located at the end of the keyhole close to the connecting lever.
[0008] The first elastic support is disposed inside the keyhole and supported at one end of the charging socket near the lever.
[0009] Beneficial effects:
[0010] The lock cylinder of this invention has a charging socket inside the keyhole. When the operator needs to unlock the lock with the key, the operator can insert the key into the keyhole and compress the first elastic support member with the key, driving the charging socket to slide along the depth direction of the keyhole to switch the charging socket to the avoidance position. After unlocking, the operator can pull the key out of the keyhole, and the charging socket can return to the charging position under the elastic restoring force of the first elastic support member.
[0011] When the door lock's battery runs out and it cannot be unlocked, the operator can plug the male charging connector into the female charging socket and use a power bank or mobile phone to power the door lock to resolve the abnormal situation. The first elastic support provides support to the female charging socket and prevents the female charging socket from retracting into the keyhole under the push of the male charging connector.
[0012] Therefore, the keyhole and charging socket of the lock cylinder of the present invention can share a common opening, thereby reducing the number of openings on the surface of the door lock, improving the waterproof and dustproof performance of the lock, and helping to improve the aesthetics of the door lock.
[0013] In one alternative implementation, the lock cylinder includes:
[0014] The first and second half cylinders are adapted to be joined together to form a columnar lock cylinder, with the keyhole formed between the first and second half cylinders.
[0015] In one alternative implementation, the charging female connector includes:
[0016] Mother base body;
[0017] The positive and negative pins are connected to the two sides of the female connector body, respectively.
[0018] The lock cylinder also includes:
[0019] The first conductive sheet is disposed on the inner peripheral wall of the lock housing and located on one side of the keyhole, and is adapted to be connected to the charging circuit of the door lock through the first wire.
[0020] The second conductive plate is disposed on the inner peripheral wall of the lock housing and located on the other side of the keyhole. It is suitable for connecting the door lock's charging circuit through the second wire. When the charging socket is in the charging position, the positive pin is connected to the first conductive plate and the negative pin is connected to the second conductive plate.
[0021] Beneficial effects:
[0022] When the charging socket is in the charging position, the positive pin is connected to the first conductive plate and the negative pin is connected to the second conductive plate, allowing the operator to power the door lock using the charging socket.
[0023] When the operator uses the key to unlock, the charging socket can be separated from the first and second conductive plates without interfering with the unlocking process.
[0024] In one alternative embodiment, a slide rail extending along the depth direction of the keyhole is formed on one of the walls of the female body and the keyhole, and a limiting buckle is formed on the other of the female body and the keyhole, the limiting buckle being adapted to slide along the slide rail.
[0025] Beneficial effects:
[0026] The limiting buckle works in conjunction with the slide rail to ensure that the female seat body can only move along the extension direction of the slide rail, making the movement of the female seat body more stable.
[0027] In one alternative implementation, the lock cylinder further includes:
[0028] Multiple lock case pin holes are formed on the lock case;
[0029] Multiple tumbler holes are formed on the tumbler and are set one-to-one with the tumbler holes on the lock case;
[0030] Multiple sets of pins, each set of pins including a first pin and a second pin that are sequentially inserted into the pin holes of the lock case and the lock cylinder;
[0031] The second elastic support is disposed in the lock case pin hole and is adapted to support the end of the first pin away from the second pin.
[0032] The pins, under the action of the second elastic support, can be locked between the cylinder and the lock case to prevent the cylinder from rotating relative to the lock case. When the operator inserts a key that matches the lock cylinder into the keyhole, the gap between the first and second pins can be aligned with the gap between the lock case and the cylinder, allowing the operator to rotate the cylinder and use a lever to unlock it.
[0033] In one alternative implementation, the charging port is a USB-C port.
[0034] Beneficial effects:
[0035] Because the male and female connectors of the USB-C interface are designed with a symmetrical structure, the insertion effect is the same on both sides, regardless of the insertion direction, allowing for blind insertion and making it more convenient to use.
[0036] In one alternative embodiment, the charging female connector is adapted to be inserted into the charging head, and the thickness of the keyhole is less than the thickness of the charging head's outer shell; and / or,
[0037] The female charging socket is designed to be plugged into the charging head, and the width of the keyhole is smaller than the width of the charging head's outer shell.
[0038] Beneficial effects:
[0039] With this design, when the operator inserts the charging head into the keyhole, the male charging head can connect with the female charging socket, and the outer shell can abut against the end face of the lock cylinder where the keyhole is located, thereby preventing the charging head from being inserted too deeply and causing the female charging socket to retract.
[0040] In one alternative implementation, the charging socket is adapted to connect to the reset circuit of the door lock's control device.
[0041] Beneficial effects:
[0042] When the door lock cannot be unlocked due to abnormal conditions such as microcontroller malfunction, the operator can connect the male charging connector to the female charging socket and use a power bank or mobile phone to provide power input to the door lock, thereby resetting the circuit and resolving the abnormal situation.
[0043] Secondly, the present invention also provides a door lock, including the lock cylinder provided in the first aspect of the present invention.
[0044] Beneficial effects:
[0045] The door lock of the second aspect of the present invention includes or uses the lock cylinder provided in the first aspect of the present invention, and thus has the beneficial effect that the keyhole and the charging socket can share a common opening, thereby reducing the number of openings on the door lock surface, improving the waterproof and dustproof performance of the lock, and helping to improve the aesthetics of the door lock.
[0046] Secondly, the present invention also provides a security door, including the door lock provided in the second aspect of the present invention.
[0047] Beneficial effects:
[0048] The security door of the third aspect of the present invention includes or uses the door lock provided in the second aspect of the present invention, and thus has the beneficial effect that the keyhole and the charging socket can share a common opening, thereby reducing the number of openings on the surface of the door lock, improving the waterproof and dustproof performance of the lock, and helping to improve the aesthetics of the door lock.

[0066] 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.
[0067] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.
[0068] According to an embodiment of the present invention, a lock cylinder is provided, comprising a lock cylinder, a lock shell 2, a charging socket 3, and a first elastic support 4. The lock cylinder has a keyhole 101 at its first end and a second end adapted to connect a lever 7. The lock shell 2 is disposed around the lock cylinder. The charging socket 3 is disposed within the keyhole 101, adapted to slide along the depth direction of the keyhole 101, and adapted to connect to the charging circuit of the lock. The charging socket 3 has a charging position and a recusal position. In the charging position, the charging socket 3 is located at the end of the keyhole 101 away from the lever 7; in the recusal position, the charging socket 3 is located at the end of the keyhole 101 close to the connecting lever 7. The first elastic support 4 is disposed within the keyhole 101 and supported by the end of the charging socket 3 close to the lever 7.
[0069] The lock cylinder of this invention has a charging socket 3 provided in the keyhole 101. When the operator needs to unlock the lock using the key 8, the operator can insert the key 8 into the keyhole 101 and compress the first elastic support 4 with the key 8, driving the charging socket 3 to slide along the depth direction of the keyhole 101 to switch the charging socket 3 to the avoidance position. After unlocking is completed, the operator pulls the key 8 out of the keyhole 101, and the charging socket 3 can return to the charging position under the elastic restoring force of the first elastic support 4.
[0070] When the door lock's battery is depleted, rendering it unable to unlock, the operator can connect the charging head 9 to the charging socket 3 and use a power bank or mobile phone to power the door lock to resolve the abnormal situation. The first elastic support 4 provides support to the charging socket 3 and prevents the charging socket 3 from retracting into the lock hole under the push of the charging head 9.
[0071] Therefore, the keyhole 101 and the charging socket 3 of the lock cylinder of the present invention can share a single opening, thereby reducing the number of openings on the surface of the door lock, improving the waterproof and dustproof performance of the lock, and helping to enhance the aesthetics of the door lock.
[0072] The first elastic support 4 is preferably, but not limited to, a spring or an elastic rubber plug. The charging female connector 3 is preferably, but not limited to, a USB-C female connector, a Lightning female connector, or a micro USB female connector.
[0073] For example, in this embodiment, the charging female connector 3 is a widely used USB-C female connector. Since the male and female connectors of the USB-C interface are designed with a symmetrical structure, the insertion effect is the same on both sides. There is no need to worry about the insertion direction, and it can be blindly inserted, making it more convenient to use.
[0074] In one embodiment, such as Figure 2 As shown, the lock cylinder includes a first half-cylinder 102 and a second half-cylinder 103. The first half-cylinder 102 and the second half-cylinder 103 are adapted to be joined together to form a cylindrical lock cylinder. A keyhole 101 is formed between the first half-cylinder 102 and the second half-cylinder 103.
[0075] As a variable implementation method, the lock cylinder is an integral cylindrical structure.
[0076] In one embodiment, the charging female connector 3 includes a female connector body 301, a positive pin 302, and a negative pin 303. The lock cylinder also includes a first conductive plate 501 and a second conductive plate 502. The positive pin 302 and the negative pin 303 are respectively connected to both sides of the female connector body 301.
[0077] The lock cylinder also includes a first conductive plate 501 and a second conductive plate 502. The first conductive plate 501 is disposed on the inner peripheral wall of the lock housing 2 and located on one side of the keyhole 101, and is adapted to be connected to the charging circuit of the lock via a first wire 503. The second conductive plate 502 is disposed on the inner peripheral wall of the lock housing 2 and located on the other side of the keyhole 101, and is adapted to be connected to the charging circuit of the lock via a second wire 504. When the charging socket 3 is in the charging position, the positive pin 302 is connected to the first conductive plate 501, and the negative pin 303 is connected to the second conductive plate 502.
[0078] This allows the positive pin 302 to be connected to the first conductive plate 501 and the negative pin 303 to be connected to the second conductive plate 502 when the charging socket 3 is in the charging position, enabling the operator to power the door lock using the charging socket 3.
[0079] When the operator uses key 8 to unlock, the charging socket 3 can be separated from the first conductive piece 501 and the second conductive piece 502, without interfering with the unlocking process.
[0080] In this embodiment, the first conductive plate 501 and the second conductive plate 502 may be disposed only at the end of the lock housing 2 away from the lever 7. In this case, the positive pin 302 is connected to the first conductive plate 501 and the negative pin 303 is connected to the second conductive plate 502 only when the charging socket 3 is in the charging position. The first wire 503 and the second wire 504 may be led outward from the gap between the lock cylinder and the lock housing 2. As an alternative embodiment, a through hole is formed on the lock housing 2, through which the first wire 503 and the second wire 504 are led outward.
[0081] As a possible implementation, the first conductive sheet 501 and the second conductive sheet 502 extend from the charging position to the avoidance position.
[0082] In one embodiment, a slide rail 104 extending along the depth direction of the keyhole 101 is formed on one of the walls of the female body 301 and the keyhole 101. A limiting buckle 304 is formed on the other of the female body 301 and the keyhole 101. The limiting buckle 304 is adapted to slide along the slide rail 104. The limiting buckle 304 cooperates with the slide groove to ensure that the female body 301 can only move along the extension direction of the slide rail 104, making the movement of the female body 301 more stable.
[0083] For example, in such Figure 2 In the illustrated embodiment, a groove is formed on each side of the keyhole 101 along its width direction. For example... Figure 4As shown, limit buckles 304 are respectively provided on both sides of the female connector body 301. The limit buckles 304 are adapted to slide along the slide groove. Preferably, an anti-detachment wall is also formed at the end of the slide groove away from the paddle 7. When the charging female connector 3 is in the charging position under the action of the first elastic support 4, the anti-detachment wall can abut against the limit buckles 304 to prevent the charging female connector 3 from disengaging from the keyhole 101.
[0084] In one embodiment, the lock cylinder further includes a plurality of lock case pin holes 201, a plurality of lock cylinder pin holes 105, a plurality of sets of pins, and a second elastic support member 603. The plurality of lock case pin holes 201 are formed on the lock case 2. The plurality of lock cylinder pin holes 105 are formed on the lock cylinder and are correspondingly arranged one-to-one with the lock case pin holes 201. Each set of pins includes a first pin 601 and a second pin 602 that are sequentially inserted into the lock case pin holes 201 and the lock cylinder pin holes 105. The second elastic support member 603 is disposed within the lock case pin holes 201 and is adapted to support the end of the first pin 601 away from the second pin 602.
[0085] The pins can be engaged in the gap between the lock cylinder and the lock housing 2 under the action of the second elastic support 603, so as to prevent the lock cylinder from rotating relative to the lock housing 2. When the operator inserts the key 8 that matches the lock cylinder into the keyhole 101, the gap between the first pin 601 and the second pin 602 can be aligned with the gap between the lock housing 2 and the lock cylinder, so as to allow the operator to rotate the lock cylinder and use the lever 7 to rotate and unlock.
[0086] The second elastic support 603 is preferably, but not limited to, a spring or an elastic plunger.
[0087] As an optional implementation method, such as Figure 3 As shown, the lock cylinder is directly connected to the lever 7. When the operator inserts the key 8 that matches the lock cylinder into the keyhole 101, the lock cylinder can be rotated, and the lock cylinder can rotate with the lever 7 to unlock.
[0088] As an alternative implementation, a linkage structure is provided between the lock cylinder and the lever 7. When the key 8 is fully inserted, it can push the linkage structure, which can link the lock cylinder and the lever 7 together. At this time, the operator can rotate the lock cylinder and unlock the lock by rotating the lever 7 through the lock cylinder. This is well known to those skilled in the art, so it will not be described in detail here.
[0089] In one embodiment, such as Figure 6 As shown, the charging female connector 3 is adapted to be inserted into the charging head 9, and the thickness of the keyhole 101 is less than the thickness of the outer shell 901 of the charging head 9; and / or,
[0090] The charging female socket 3 is suitable for plugging into the charging head 9, and the width of the keyhole 101 is smaller than the width of the outer shell 901 of the charging head 9.
[0091] With this configuration, when the operator inserts the charging head 9 into the keyhole 101, the male charging head 902 of the charging head 9 can be connected to the female charging socket 3, and the outer shell 901 can abut against the end face of the lock cylinder where the keyhole 101 is located, thereby preventing the charging head 9 from being inserted too deeply, which would cause the female charging socket 3 to retract.
[0092] Preferably, such as Figure 5 As shown, the width of the key handle is set to be greater than the width of the keyhole 101; and / or, the thickness of the key handle is set to be greater than the thickness of the keyhole 101, thereby preventing the key 8 from being inserted too deeply and causing damage to the charging socket 3.
[0093] In one embodiment, the charging socket 3 is adapted to connect to the reset circuit of the door lock's control device. The control device may include a programmable logic controller (PLC or CPU), a memory, and electronic components connected to the PLC, which are well-known to those skilled in the art and will not be described in detail here. As an optional implementation, the control device is a microcontroller. When the door lock cannot be unlocked due to an abnormality such as a microcontroller crash, the operator can plug the charging head 9 into the charging socket 3 and use a power bank or mobile phone to provide a 5V power input to the door lock, resetting the circuit and resolving the abnormality.
[0094] According to an embodiment of the present invention, in another aspect, a door lock is also provided, including the lock cylinder provided in the first aspect of the present invention.
[0095] The door lock of the second aspect of the present invention includes or uses the lock cylinder provided in the first aspect of the present invention, and thus has the beneficial effect that the keyhole 101 and the charging female socket 3 can share a common opening, thereby reducing the number of openings on the surface of the door lock, improving the waterproof and dustproof performance of the lock, and helping to improve the aesthetics of the door lock.
[0096] The following describes how to use the door lock of this invention:
[0097] When the door lock needs to be charged, first insert the USB charging head 9 into the keyhole 101. Since the size of the outer shell 901 of the USB charging head 9 is larger than the size of the keyhole, only the male charging head 902 can be inserted into the keyhole 101 and connect with the female charging connector 3, thereby charging the battery or resetting the circuit. After charging is complete, the operator removes the USB charging head 9.
[0098] When it is necessary to use key 8 to unlock, the operator can insert key 8 into keyhole 101. The size of key 8 is smaller than the size of keyhole 101, so key 8 can be inserted into lock cylinder to allow the operator to turn lever 7 to unlock.
[0099] After unlocking is complete, the operator removes the key 8, and the first elastic support 4 drives the charging socket 3 to reset through its own elastic restoring force.
[0100] According to an embodiment of the present invention, in another aspect, a security door is also provided, including the door lock provided in the second aspect of the present invention. The security door of the third aspect of the present invention includes or uses the door lock provided in the second aspect of the present invention, and therefore has the beneficial effect that the keyhole 101 and the charging socket 3 can share a common opening, thereby reducing the number of openings on the surface of the door lock, improving the waterproof and dustproof performance of the lock, and helping to improve the aesthetics of the door lock.
[0101] 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.
