When the vibration switch 11 detects that the body vibrates in a set state, an alarm is issued. The set state can be selected but not limited to the body of the two-wheeled vehicle is in an unactivated locked state. When the body is illegally touched, the body vibrates. When the vibration switch 11 detects the vibration of the body, it sends a detection signal to the controller in the lock body. After receiving the signal, the controller controls the speaker 12 to alarm; or when the vibration switch 11 detects the vibration of the body, it directly triggers the switch connected to the speaker 12 to turn on, so that the speaker 12 starts to alarm. The speaker 12 is preferably integrated in the lock body, so that there is no need to set up an additional speaker 12 and wiring, reducing the complexity of installation.

[0032] Thus, the utility model provides a multifunctional composite lock which, in addition to having a locking function, also integrates an alarm function. The alarm on the vehicle body is integrated into the lock body, which can well optimize the cost of the entire vehicle.

[0033] The multifunctional compound lock can be any lock on the vehicle body. Preferably, the multifunctional compound lock is used as a seat bucket lock of a two-wheeled vehicle, and is used in conjunction with a seat cushion above the seat bucket to lock the seat cushion and prevent the items in the seat bucket from being stolen.

[0034] Furthermore, the lock body is installed in the seat bucket, and the lock body includes a lock hook 31 for locking with the buckle under the seat cushion. The lock body is also integrated with a seat bucket light 13, and the lock body is also provided with a detection switch 14 for detecting the state of the lock body. The seat bucket light 13 is set toward the seat bucket. When the detection switch 14 detects that the lock body is in the unlocked state, that is, the seat cushion is out of the lock and ready to be opened, the seat bucket light 13 is turned on for lighting, which is convenient for taking and placing items in the seat bucket; when the detection switch 14 detects that the lock body is in the locked state, that is, the seat cushion is closed and locked, the seat bucket light 13 is automatically turned off. The detection switch 14 is preferably a position switch for detecting the position of the lock hook 31, such as a micro switch, a proximity switch or a photoelectric switch. Since the positions of the lock hook 31 are different in the unlocked state and the locked state, the position of the lock hook 31 can be detected by the position switch, thereby indirectly judging the state of the lock body, that is, when the lock hook 31 is in the unlocked position, the bucket light 13 is turned on; when the lock hook 31 is in the locked position, the bucket light 13 is turned off.

[0035] The vibration switch 11, the horn 12 and the bucket light 13 of the utility model are all integrated on the PCB board 16. The PCB board 16 is arranged on the front side of the lock body. The rear side of the lock body is provided with a locking assembly 3 and an unlocking assembly 4. The locking assembly 3 includes a lock tongue 32 in addition to the aforementioned lock hook 31. The lock tongue 32 limits the lock hook 31 through a limiting portion 33. The lock tongue 32 and the lock hook 31 are both hingedly installed and can rotate around the hinge axis. The unlocking assembly 4 is used to unlock the locking assembly 3, specifically by driving the lock tongue 32 to rotate in the unlocking direction. In this way, the utility model sets the PCB board 16 on the entire front of the lock body, so that the size of the PCB board 16 can be designed to be larger, and the above components can be configured. In addition, it can also have other functions, such as a radio frequency antenna 15 that supports 315MHz, 433MHz, and 2.4G; a Bluetooth module is provided to realize communication with terminals such as mobile phones; a communication port is provided to support K-line communication, 485 communication, CAN bus communication, one-line communication, serial communication, etc.

[0036] The seat bucket lock in the prior art is generally made of metal, which makes it difficult to process and has an unsightly appearance. The utility model provides a metal lock plate 21 in the lock body, on which the lock hook 31 and the lock tongue 32 are hingedly provided to ensure strength. The metal lock plate 21 is also provided with a mounting seat 211, which can be installed on the vehicle body; a plastic shell 22 is also wrapped around the metal lock plate 21, which is convenient for processing and structural layout, and the appearance of the product is also optimized.

[0037] The plastic shell 22 includes a front panel 221 and a rear panel 222 arranged front and rear, the front panel 221 correspondingly covers the PCB board 16, the front panel 221 is provided with a sound hole 2211 corresponding to the speaker 12, and is provided with a light-transmitting opening 2212 or a transparent area corresponding to the bucket light 13; the rear panel 222 correspondingly covers the locking component 3 and the unlocking component 4.

[0038] The unlocking assembly 4 includes a driving motor 41, a worm gear 42, a gear set 43, a rack 44 and an output rod 45. A worm gear is arranged at the output end of the driving motor 41, and the worm gear is meshed with a worm to form a worm gear 42. The worm gear 42, the gear set 43 and the rack 44 are meshed in sequence, and the rack 44 can slide along a slideway arranged in the plastic shell 22; an insertion portion 451 is formed at one end of the output rod 45 to be slidably inserted into the rack 44, and the insertion portion 451 includes two limit blocks 452 arranged relatively along the moving direction of the output rod 45, and an opening 441 is formed in the rack 44, and a movable member is inserted into the opening 441. The movable spring 46, the two ends of the movable spring 46 are respectively inserted into the two limit blocks 452, and the two ends of the movable spring 46 are both against the output rod 45 and the rack 44, specifically, one end of the movable spring 46 is against the root end plane of one of the limit blocks 452 on the output rod 45 and one of the inner side walls of the opening 441 of the rack 44, and the other end of the movable spring 46 is against the root end plane of another limit block 452 on the output rod 45 and the other opposite inner side wall of the opening 441 of the rack 44. When the rack 44 moves, the movable spring 46 can be compressed first, and the movable spring 46 can push the output rod 45 to move after accumulating force. In this way, the flexible transmission of force is realized by designing the movable spring 46. Even if an extreme situation is encountered, the lock hook 31 and the lock tongue 32 are stuck, and the output force of the drive motor 41 will be stored in the movable spring 46, and the drive motor 41 and the gear set 43 will not be blocked, thereby protecting the drive motor 41 and the gear, and greatly improving the reliability of the whole machine. In addition to realizing electronic unlocking through the driving motor 41 , the unlocking assembly 4 also includes a pull wire 47 for manual unlocking, and the inner end of the pull wire 47 is connected to the lock tongue 32 .

[0039] In the prior art, a torsion spring is generally provided on the lock hook 31 and the lock tongue 32, respectively, or a tension spring is provided between the two to provide the reset force of the two. In the present utility model, only a reset torsion spring 311 is provided on the lock hook 31, and the reset force and the limiting force of the lock tongue 32 are provided by the movable spring 46. Specifically, the output rod 45 is provided with a dialing hole 453 that can cover the unlocking end of the lock tongue 32. The dialing hole 453 is preferably C-shaped, which can drive the lock tongue 32 to move in two directions and is convenient to install. When unlocking, the output rod 45 first drives the lock tongue 32 to rotate in the unlocking direction through one side of the dialing hole 453 to unlock, and then the output rod 45 moves in the opposite direction through the other side of the dialing hole 453 to drive the lock tongue 32 to rotate in the opposite direction. After the seat cushion is lowered and locked, the lock tongue 32 is reset under the action of the movable spring 46, and the lock hook 31 is limited by the limiting part 33. At this time, the movable spring 46 is in a compressed state, and its pressure is much greater than the torsion spring used in the prior art, and its force arm for moving the lock tongue 32 is also longer, so it can prevent the lock from being unlocked under the action of a large external force.

[0040] The multifunctional composite lock of the utility model can be used as a seat bucket lock of a two-wheeled vehicle. When the vehicle owner closes the seat cushion, the lock hook 31 is forced to rotate, the lock tongue 32 limits the lock hook 31, and the lock is automatically closed. The unlocking methods include electronic unlocking and manual unlocking.

[0041] Among them, when electronic unlocking is controlled by a mobile phone app or a remote control key, after the drive motor 41 receives the unlocking command, it first rotates in the unlocking direction, for example, in the clockwise direction, and the worm gear 42 and the gear set 43 also rotate accordingly. The torque can be amplified by the worm gear 42 and the gear set 43, and the rack 44 cooperates with the last gear of the gear set 43, so that the rack 44 can move in a straight line; when the rack 44 moves in a straight line, the active spring 46 inside it is first compressed, so that the active spring 46 deforms and stores energy, and then the active spring 46 will apply force to the output rod 45, driving the output rod 45 to move, and the output rod 45 drives the lock tongue 32 to rotate in the unlocking direction, releasing the limit of the lock tongue 32 on the lock hook 31, and the lock hook 31 is unlocked under the action of the reset torsion spring 311.

[0042] Then the driving motor 41 rotates in the opposite direction, the worm gear 42, the gear set 43 and the rack 44 all move in the opposite direction, the rack 44 moves in the opposite direction to the initial position, and the output rod 45 drives the locking tongue 32 to rotate in the opposite direction by a certain angle; at this time, it is still in the unlocked state, the locking tongue 32 does not limit the lock hook 31, and the movable spring 46 is also in a compressed state. When the lock hook 31 returns to the locked state under the downward pressure of the seat cushion, the movable spring 46 releases a certain deformation force to push the locking tongue 32 to the limited state of the lock hook 31 to achieve reset.

[0043] The manual unlocking is performed by rotating the mechanical key to pull the pull wire 47, thereby driving the lock tongue 32 to rotate to unlock.

[0044] From the above content, it can be seen that the utility model provides a multifunctional composite lock, which is fixedly installed on the vehicle body. When the vehicle body is illegally touched, the vibration switch integrated in the multifunctional composite lock can detect the vibration of the vehicle body and issue an alarm, thereby expanding the function of the lock and optimizing the cost of the entire vehicle.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
