[0035] like Figure 1-7As shown, the present embodiment provides a seat lock for locking a seat on a two-wheeled vehicle, the seat lock is integrated with a light-emitting module 11 and a detection module 12, wherein the light-emitting module 11 is a module capable of generating light, and the generated light can be used for lighting, prompting or decoration, etc.; the detection module 12 is a position switch capable of detecting the state of the seat lock, which can be specifically selected but not limited to a micro switch, a proximity switch, etc. Specifically, a lock hook 41 is provided in the seat lock for locking in cooperation with a lock buckle under the seat, when the seat is pressed down to lock and when the seat is unlocked and opened, the lock hook 41 is in different position states, and a position switch is provided near the lock hook 41 to detect the state of the lock hook 41, so that it can be determined whether the seat lock is in a locked state or an unlocked state, when it is detected that the lock hook 41 is in the unlocked position, it indicates that the seat lock is in an unlocked state, and the light-emitting module 11 is lit, and when it is detected that the lock hook 41 is in a locked state, it indicates that the seat lock is in a locked state, and the light-emitting module 11 is extinguished.

[0036] Alternatively, in other embodiments, the detection module 12 can also be a position switch for detecting the position of the seat cushion, which can be specifically selected but not limited to a distance switch, a proximity switch, etc. When the seat cushion is opened and closed, the distance between it and the seat cushion lock changes. When the seat cushion is opened to a first preset position, the light-emitting module 11 is turned on, and when the seat cushion is lowered to a second set position, the light-emitting module 11 is turned off. The first preset position and the second preset position can be set as needed.

[0037] In this way, the cushion lock provided in this embodiment integrates a light-emitting module 11 and a detection module 12. The cushion lock is generally installed in a storage bin below the cushion through a mounting portion 21. The light-emitting module 11 is preferably a lighting lamp facing the storage bin, so that when the cushion is opened at night or in dim light, the storage bin can be illuminated to facilitate the taking and placing of items. Moreover, the lighting function is directly integrated into the cushion lock, without the need for additional lamps and wiring, thereby reducing the complexity of installation and control. Of course, in other embodiments, the light-emitting module 11 can also be a flashing light for prompting or a running light for decoration, etc., to increase the function of the cushion lock and enhance the intelligence of the cushion lock.

[0038] Furthermore, in this embodiment, a vibration switch 13 and a speaker 14 are integrated on the seat lock. The seat lock is fixedly installed in the storage compartment under the seat of the vehicle body. When the vibration switch 13 detects that the vehicle body vibrates under a preset state, the speaker 14 is triggered to alarm. The preset state can be selected but not limited to the vehicle being in an unstarted parking state. When the vehicle is illegally touched, an alarm is sounded. In this way, the alarm function is further integrated on the seat lock, further increasing the function of the seat lock. Moreover, the seat lock and the alarm, which are both anti-theft components, are integrated into one product, which can eliminate the original alarm of the vehicle and optimize the cost of the vehicle.

[0039] The seat lock of this embodiment is also provided with a circuit board 1, on which the light module 11, the vibration switch 13 and the speaker 14 are arranged, and the circuit board 1 is arranged on the front of the seat lock. The seat lock also includes a locking component 4 and an unlocking component 5, and the locking component 4 and the unlocking component 5 are arranged on the back of the seat lock. In this embodiment, the locking component 4 and the unlocking component 5 are both arranged on the back, and the layout is reasonable and compact. The size of the circuit board 1 can be designed to be larger, which is convenient for setting the light module 11, the vibration switch 13 and the speaker 14, and more functions can be integrated on the circuit board 1. For example, a communication interface is also provided on the circuit board 1, which can support one-line communication, K-line communication, serial communication, 485 communication and CAN bus communication, etc. according to needs; a radio frequency antenna 15 is also provided on the circuit board 1, which can cooperate with the remote control key and support 315MHz, 433MHz and 2.4G radio frequencies; a Bluetooth module can also be provided on the circuit board 1 to connect to a mobile phone app.

[0040] The seat lock of this embodiment includes a plastic shell 3 and a metal lock plate 2 located in the middle of the plastic shell 3, and a locking assembly 4 is arranged on the metal lock plate 2. In this way, the appearance of the seat lock is greatly optimized while ensuring the strength through the design of plastic parts encapsulating metal parts. Furthermore, the plastic shell 3 includes a first cover plate 31 and a second cover plate 32 located on the front and rear sides. The first cover plate 31 is provided with a sound-transmitting hole 311 corresponding to the speaker 14, and a light-transmitting port 312 or a transparent area capable of transmitting light corresponding to the light-emitting module 11; the second cover plate 32 covers the locking assembly 4 accordingly.

[0041] Furthermore, the locking assembly 4 includes a rotatable lock hook 41 and a lock tongue 42, which cooperate to lock, and a clamping portion 43 is formed between the lock hook 41 and the lock tongue 42. Reset torsion springs can be respectively provided on the lock hook 41 and the lock tongue 42, or a reset tension spring can be provided between the lock hook 41 and the lock tongue 42. When the seat lock is in a locked state, the lock tongue 42 clamps the lock hook 41 through the clamping portion 43 under the action of elastic force to prevent the lock hook 41 from resetting under the action of the elastic force; when unlocking is required, the lock tongue 42 rotates to release the clamping of the lock hook 41, and the lock hook 41 can be reset under the action of the elastic force to achieve unlocking.

[0042] The unlocking assembly 5 includes a driving module 51 and a driving rod 52. The driving module 51 drives the lock tongue 42 to move to unlock through the driving rod 52. Specifically, the driving module 51 includes a driving motor 511, a worm gear 512, a gear set 513 and a rack 514. The output end of the driving motor 511 is provided with a worm gear 512. The worm gear 512, the gear set 513 and the rack 514 are meshed in sequence. The driving motor 511 drives the rack 514 to move through the worm gear 512 including a worm and a worm wheel and the gear set 513. A slide groove can be provided in the plastic housing 3 to facilitate the sliding of the rack 514. The driving rod 52 slides through the rack 514, and the driving rod 52 is located at the rack The portion inside the rack 514 is provided with two anti-slip blocks 521 which are arranged opposite to each other along the movement direction of the driving rod 52. An opening 5141 is also provided on the rack 514 corresponding to the insertion portion of the driving rod 52. A transmission spring 53 is also provided in the rack 514. The transmission spring 53 is inserted into the opening 5141. Its two ends are respectively sleeved on the two anti-slip blocks 521, and its two ends both abut against the rack 514 and the driving rod 52, specifically, one end abuts against the first inner side wall of the opening 5141 of the rack 514 and the root of one of the anti-slip blocks 521 of the driving rod 52, and the other end abuts against the other relative inner side wall of the opening 5141 of the rack 514 and the root of the other anti-slip block 521 of the driving rod 52. In this way, through the design of the transmission spring 53, flexible transmission of force between the rack 514 and the drive rod 52 is achieved. Even in extreme situations, the lock hook 41 and the lock tongue 42 are stuck, and the output force of the drive motor 511 will be stored in the transmission spring 53, and the drive motor 511 and the gear set 513 will not be blocked, thereby protecting the drive motor 511 and the gear set 513, thereby greatly improving the reliability of the seat lock product itself.

[0043] Furthermore, in this embodiment, an elastic reset member 411 is provided on the lock hook 41, which can be, but not limited to, a torsion spring. However, the elastic reset member 411 is not provided on the lock tongue 42, but the transmission spring 53 is used to provide a reset force. Specifically, a hoop 522 capable of clamping the lock tongue 42 is provided on the end of the driving rod 52 close to the lock tongue 42, that is, the driving rod 52 can drive the lock tongue 42 to move in two directions, and the hoop 522 can be, but not limited to, C-shaped, U-shaped, square or circular. When unlocking, the driving motor 511 rotates clockwise, and the driving force is transmitted to the rack 514. The transmission spring 53 pushes the driving rod 52, and the lock tongue 42 is first driven to move in the unlocking direction through one side of the hoop 522 of the driving rod 52, that is, ( Figure 6 The lock tongue 42 is driven to rotate in the opposite direction (i.e., the lock tongue 42 rotates in the opposite direction) through the other side of the hoop 522 of the drive rod 52, and then the drive motor 511 rotates counterclockwise, and the transmission spring 53 pushes the drive rod 52 in the opposite direction. Figure 6The transmission spring 53 provides a reset force, and when the owner of the car closes the seat cushion after using it, the lock hook 41 on the seat cushion lock is automatically locked by force. At this time, under the action of the transmission spring 53, the lock tongue 42 is also completely reset to engage the lock hook 41. In this way, the reset piece of the lock tongue 42 can be omitted, and the transmission spring 53 is in a compressed state, and its elastic force is much greater than the torsion of the torsion spring used in the prior art, and the force arm of the driving rod 52 pushing the lock tongue 42 is also longer. In this way, through the connection design of the lock tongue 42 and the driving rod 52, the hidden danger of the seat cushion lock being forcibly unlocked under the action of a large external force on the market can be solved, and the reliability of the seat cushion lock when locked can be greatly improved.

[0044] Furthermore, the unlocking assembly 5 also includes a pull rope 54, which is connected to the lock tongue 42, and can be manually unlocked by pulling the lock tongue 42 with the help of the pull rope 54 using a mechanical key.

[0045] The seat lock provided in this embodiment is automatically locked by force when the owner closes the seat. When unlocking is required, the lock can be manually unlocked by pulling the lock tongue 42 by pulling the pull rope 54, or electronic unlocking can be achieved by remote control, mobile phone app, etc. When electronic unlocking is performed, the drive motor 511 first rotates clockwise to drive the worm gear 512 to rotate, and the worm gear 512 drives the gear set 513 to move, amplifying the torque of the drive motor 511, and then the last gear and rack 514 cooperate to convert the rotational motion into linear motion. The rack 514 then compresses the internal transmission spring 53, and the transmission spring 53 accumulates force through deformation, thereby pushing the drive rod 52 to move, and the drive rod 52 drives the lock tongue 42 to rotate in the unlocking direction, thereby releasing the locking limit of the lock tongue 42 on the lock hook 41, and the lock hook 41 acts on the elastic reset member 411. The worm gear 512 and the gear set 513 rotate in the opposite direction, and the rack 514 moves in the opposite direction to the initial position. At this time, the driving rod 52 and the lock tongue 42 are connected, driving the lock tongue 42 to rotate in the opposite direction by a certain angle. Since it is still in the unlocked state at this time, the lock tongue 42 is not engaged with the lock hook 41, and the transmission spring 53 is in a state of deformation and force storage. When the lock hook 41 is pressed back to the locked state under the seat cushion, the transmission spring 53 releases a certain deformation force to push the lock tongue 42 to the limit state of the lock hook 41 to achieve reset.

[0046] From the above content, it can be seen that the seat cushion lock provided in this embodiment integrates a light-emitting module and a detection module, so that the seat cushion lock also has functions such as lighting, thereby improving the intelligence level of the seat cushion lock and improving the convenience during use.

[0047] 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.
