Description
Technical Field

[0002] U-shaped locks are one of the commonly used locks. With the advancement of technology, the structure of U-shaped locks has been continuously improved. However, most U-shaped locks still use a structure in which a key is inserted into the lock cylinder and rotated to lock or unlock. When using a U-shaped lock with this structure, the key needs to be aligned with the keyhole in the lock body and inserted into the specified position before the lock cylinder can be rotated. Otherwise, the lock cylinder will become stuck, which may easily cause the lock body and the lock beam to be unable to connect, lock, or disconnect, and the unlocking and locking operations are also relatively complicated.
[0003] To address this issue, some U-shaped locks have been designed that are intelligently controlled by electronic devices. Although these new electronic U-shaped locks can provide some convenience, if the electronic device-controlled U-shaped lock is not equipped with a corresponding backup lock structure to cope with the above emergency situations due to insufficient power or device failure, the electronic U-shaped lock cannot be unlocked or locked, and the working stability of the lock body structure still needs to be improved.

[0029] The utility model discloses a U-shaped lock body structure, such as Figures 1 to 4 As shown in combination, the lock body structure includes a shell 1, both sides of the shell 1 are provided with connecting holes 11 for inserting the lock beam of the U-shaped lock, a sliding channel 12 connected to the connecting hole 11 is provided in the shell 1, and a first slide bar 2 and a second slide bar 3 are respectively provided in the sliding channel 12, the middle part of the first slide bar 2 is provided with a connecting column 21, the outer side of the connecting column 21 is sleeved with a spring, and the end of the second slide bar 3 is provided with a protrusion 31, one end of the spring abuts against the protrusion 31, a first matching cavity 13 is provided in the shell 1 outside the sliding channel 12, a driving device 4 is provided in the first matching cavity 13, a second matching cavity 14 is provided in the shell 1 outside the driving device 4, and a spare lock core 5 is provided in the second matching cavity 14, the spare lock core 5 and the driving device 4 are used to drive the first slide bar 2 and the second slide bar 3 to move at both ends of the sliding channel 12 and in the connecting hole 11 respectively, and a switch device 6 electrically connected to the driving device 4 is provided on the surface of the shell 1.
[0030] It should be noted that: if both the first slide bar 2 and the second slide bar 3 are completely in the sliding channel 12, the lock body structure is in the unlocked state, and the spring in the extended state will push the part with the protrusion 31 on the second slide bar 3, and then use the effect of the first slide bar 2 of the spring itself to make the first slide bar 2 and the second slide bar 3 close to the driving device 4. If it is necessary to lock the lock beam of the U-shaped lock inserted into the connecting hole 11 at this time, the driving device 4 is controlled to work through the switch device 6. After the driving device 4 is started, a force is applied to the spring, causing the spring, which was originally in the extended state, to be compressed, and the sliding channels 12 of the first slide bar 2 and the second slide bar 3 to move outward, so that the first slide bar 2 and the second slide bar 3 are locked. The ends of the two slide bars 3 move from the sliding channel 12 into the connecting hole 11 and are clamped on the lock beam, thereby fixing the lock beam in the connecting hole 11, and then realizing the connection between the lock body and the lock beam. At this time, the U-shaped lock is in a locked state; and when unlocking the U-shaped lock, it is only necessary to operate the switch device 6 again; the lock body structure uses the switch device 6 to control the drive device 4 to drive the first slide bar 2 and the second slide bar 3 to move. It replaces the traditional lock body's manual control of the first slide bar 2 and the second slide bar 3 by a key to move into or out of the connecting hole 11, achieving the effect of intelligently controlling the locking and unlocking between the lock body and the lock beam, making the opening and locking operations of the lock easier.
[0031] In addition, the lock body structure also has a spare lock core 5. When the drive device 4 cannot be used normally, the lock body can be locked and unlocked on the lock beam by manual operation of the key, thereby increasing the working stability of the lock body.
[0032] It needs to be further explained that, Figures 3 to 7 As shown in combination, the driving device 4 includes a motor 41 and a first rotating end 42, the motor 41 is fitted in the first fitting cavity 13, the shell 1 outside the first fitting cavity 13 is provided with a first fitting hole 15, the output end of the motor 41 extends into the first fitting hole 15 and is connected to the first rotating end 42, the surface of the first slide bar 2 is provided with a first protrusion 22, the surface of the second slide bar 3 is provided with a second protrusion 32, the protrusion 31 is located at the end of the second protrusion 32, the first rotating end 42 is circumferentially provided with at least two first protrusions 421 away from the end connected to the output end of the motor 41, and the first protrusion 421 extends into the sliding channel 12 for rotation.
[0033] Among them, after the switch device 6 controls the driving device 4 to start, the motor 41 works and drives the first rotating end 42 to rotate. If the first sliding rod 2 and the second sliding rod 3 are both completely in the sliding channel 12 at this time, the first boss 421 will abut the side walls of the first protrusion 22 and the second protrusion 32. When the first boss 421 rotates with the first rotating end 42, the spring will be compressed to cause the second protrusion 32 to move toward the first rotating end 42; at the same time, due to the rotation of the first boss 421, the first protrusion 22 will be pushed by the first boss 421 and move to the position where one of the connecting holes 11 is located, so that the second sliding rod 3 moves out of the sliding channel 12, and the second protrusion 3 2 will also be pushed by the rotating first protrusion 421 to move toward the position where the other connecting hole 11 is located, so that the first sliding bar 2 moves out of the sliding channel 12; after the ends of the first sliding bar 2 and the second sliding bar 3 move out of the sliding channel 12 and enter the connecting hole 11, the ends of the first sliding bar 2 and the second sliding bar 3 will be engaged with the engaging parts on the lock beam, thereby locking the lock beam and putting the U-shaped lock into a locked state; and when the U-shaped lock is unlocked, the switch device 6 controls the drive device 4 to work, so that the first sliding bar 2 and the second sliding bar 3 move in the opposite directions so that the ends of the two no longer lock the lock beam of the U-shaped lock, thereby putting the U-shaped lock into an unlocked state.
[0034] Specifically, if Figure 3 、 Figure 5 and Figure 8 As shown in the combination, the first matching hole 15 is stepped, the cross-section of the first matching hole 15 close to the motor 41 is U-shaped, and the first rotating end 42 close to the motor 41 is provided with a first limit block 422, and the end of the first limit block 422 is a right angle 423, and the right angle 423 moves in the space with a U-shaped cross-section in the first matching hole 15.
[0035] Since the driving device 4 drives the first slide bar 2 and the second slide bar 3 to move by the output end of the motor 41 in a two-way motion, and it is necessary to use a limiting structure to limit the unidirectional rotation stroke of the output end of the motor 41 to ensure that the motor 41 does not overtravel; therefore, the first limit block 422 set on the first rotating end 42 and the contour of the first matching hole 15 are combined to limit the rotation action of the first rotating end 42 when the motor 41 drives the first rotating end 42 to rotate, the right angle 423 on the first limit block 422 is abutted against the wall surface of the first matching hole 15 to limit the rotation action of the first rotating end 42. When the output end of the motor 41 overtravels, it will be unable to move due to the restriction of the first matching hole 15 to avoid the end ends of the first slide bar 2 and the second slide bar 3 being damaged due to hard extrusion with the lock beam, and the movement range of the right angle 423 when the first rotating end 42 rotates is within the space with a U-shaped cross-section in the first matching hole 15, which will not affect the action of the motor 41 driving the first rotating end 42 to rotate.
[0036] It needs to be further explained that, Figure 3 、 Figure 9 、 Figure 10 and Figure 11 As shown in the figure, the spare lock cylinder 5 includes a socket 51 and a second rotating end 52. The socket 51 is matched in the second matching cavity 14. One end of the socket 51 is provided with a socket 511 for inserting a key. The housing 1 outside the second matching cavity 14 is provided with a second matching hole 16. The other end of the socket 51 extends into the second matching hole 16 and is connected to the second rotating end 52. The surface of the first slide bar 2 is provided with a third protrusion 23, and the surface of the second slide bar 3 is provided with a fourth protrusion 33. The second rotating end 52 is circumferentially provided with at least two second protrusions 521 away from the end connected to the socket 51. The second protrusion 521 extends into the sliding channel 12 for rotation.
[0037] When the spare lock cylinder 5 needs to be used, the key can be inserted into the socket 511 of the socket 51 through the second matching cavity 14, and the socket 51 can be controlled to rotate by twisting the key, and the second rotating end 52 rotates with the socket 51; if the first slide bar 2 and the second slide bar 3 are both completely in the sliding channel 12 at this time, the second protrusion 521 will abut against the side walls of the third protrusion 23 and the fourth protrusion 33, and when the second protrusion 521 rotates with the second rotating end 52, the spring will be compressed to make the fourth protrusion 33 move toward the second rotating end 52; at the same time, due to the rotation of the second protrusion 521, the third protrusion 23 will be pushed by the second protrusion 521 and move to the position where one of the connecting holes 11 is located, so that the second slide bar 2 and the second slide bar 3 are completely in the sliding channel 12 When the U-shaped lock is unlocked, the driving device 4 is controlled to work so that the first slide bar 2 and the second slide bar 3 move in opposite directions so that the ends of the two slide bars no longer lock the lock beam of the U-shaped lock, thereby achieving the unlocked state of the U-shaped lock.
[0038] Specifically, if Figure 3 、 Figure 9 and Figure 12 As shown in the figure, the inner wall of the shell 1 outside the second matching hole 16 is provided with a limiting groove 17 with a fan-shaped cross-section and connected to the second matching hole 16, and the side wall of the second rotating end 52 is provided with a second limiting block 522 extending away from the center of the second rotating end 52, and the second limiting block 522 is located in the limiting groove 17.
[0039] In order to make the spare lock cylinder 5 reciprocate and achieve the purpose of controlling the two-way movement of the first slide bar 2 and the second slide bar 3, the second limit block 522 set on the second rotating end 52 moves in the limit groove 17 to limit the rotation stroke of the second rotating end 52, thereby limiting the rotation range of the second rotating end 52 to the central angle range of the limit groove 17, thereby preventing the spare lock cylinder 5 from over-forming, and avoiding the ends of the first slide bar 2 and the second slide bar 3 from being damaged due to hard squeezing with the lock beam, which is beneficial for the spare lock cylinder 5 to maintain a stable state so that the lock can be opened normally in an emergency.
[0040] It needs to be further explained that, Figure 13As shown, a circuit board 7 is provided in the shell 1 outside the switch device 6, and a battery 71 is provided on the surface of the circuit board 7 away from the first matching cavity 13. The shell 1 outside the battery 71 is provided with a panel 8, and a display screen 81 is provided on the surface of the panel 8. The battery 71 is electrically connected to the switch device 6 and the display screen 81 respectively.
[0041] The battery 71 provides power for the operation of the driving device 4 and the display screen 81 , and the display screen 81 can display the current power level of the battery 71 , so that the user can clearly understand whether the current power level of the battery 71 is sufficient.
[0042] Specifically, if Figure 3 As shown, a USB interface 9 is provided in the housing 1 outside the circuit board 7 , and the USB interface 9 is electrically connected to the circuit board 7 .
[0043] The external power source is connected to the USB interface 9 via a power transmission line to replenish power to the battery 71 to maintain the normal operation of the lock body.
[0044] More specifically, if Figure 3 As shown, the housing 1 outside the USB interface 9 and the second matching cavity 14 is provided with a matching groove 18 , and a sealing plug 91 is matched in the matching groove 18 .
[0045] Among them, by fitting the sealing plug 91 in the fitting groove 18, the ports of both the USB interface 9 and the second fitting cavity 14 can be sealed, thereby preventing foreign objects from entering the space of the shell 1 where the two are located when charging is not needed and the spare lock cylinder 5 is in use, causing damage to the USB interface 9 and the spare lock cylinder 5.
[0046] It needs to be further explained that, Figure 2 As shown, a sealing groove 19 is provided on the wall surface of the housing 1 outside the two ends of the sliding channel 12 , and a sealing ring 10 is fitted in the sealing groove 19 .
[0047] The sealing rings 10 are arranged at both ends of the sliding channel 12 to prevent foreign objects from entering the sliding channel 12 from both ends, causing the first sliding bar 2 and the second sliding bar 3 to be unable to move normally or to be damaged.
[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
