Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a first locking mechanism is provided on the lid 2 corresponding to the box body 1. The first locking mechanism includes a cover hook 21 installed on the lid 2 and a lock hook 11 located inside the box body 1 corresponding to the cover hook 21. The cover hook and lock hook are made of high-strength aluminum alloy or engineering plastic and are coated with an anti-rust coating to improve service life. A second locking mechanism is provided on the contact surface of the cover hook 21 and the lock hook 11 to provide secondary fixation and prevent accidental opening when the first locking mechanism fails, ensuring the stability of the lock body under bumpy conditions. A layer is provided on the inner side of the front wall of the box body 1, and the lock hook 11 is installed in the layer. A rotating shaft 12 is provided at the bottom of the lock hook 11, and a servo motor is connected to the rear of the rotating shaft 12. An intelligent control module 6 and a status feedback module 7 are provided on the surface of the front wall of the box body 1. The double locking mechanism improves the reliability of the locking structure through the elastic locking tongue structure on the cover hook, ensuring the stability of the lock body under bumpy conditions. It integrates fingerprint recognition or Bluetooth control to adapt to multiple scenario needs and improve anti-theft performance.

[0021] A locking detection sensor 3 is installed inside the interlayer of the housing 1. The top of the locking detection sensor 3 is connected to an elastic pressure plate 31 located below the cover hook 21. A detection contact 32 is provided between the elastic pressure plate 31 and the locking detection sensor 3. When the housing is closed, the cover hook abuts against the elastic pressure plate. After the elastic pressure plate deforms, it abuts against the detection contact, transmitting a locking signal.

[0022] A first limiting block 4 is provided on the side of the locking hook 11 close to the locking detection sensor 3, and a second limiting block 5 is provided on the side of the locking hook 11 away from the locking detection sensor 3, providing front and rear limits for the locking hook.

[0023] The second locking mechanism includes at least two sets of latches 211 disposed on the contact surface of the cover hook 21. A guide rod 212 embedded in the cover hook 21 is connected to the bottom of each latch 211. A spring structure 213 connecting the bottom of the latch 211 to the contact surface of the cover hook 21 is disposed on the outside of the guide rod 212. A first groove 111 is formed on the contact surface of the cover hook 11. A unidirectional second groove 112 is formed above the first groove 111. A matching through hole is formed in the first groove 111 corresponding to the position of the latch 211. The bottom of the through hole is chamfered to facilitate the latch's smooth exit from the through hole. A sliding rod 113 is movably installed in the second groove 112. The end of the sliding rod 113... The connecting plate is connected to the output end of the electric push rod 114 installed on the top of the lock hook 11, driving the slide rod 113 to slide in the second slide groove 112. In the locked state, the electric push rod pushes the slide rod out of the second slide groove, exposing two sets of through holes. When the lock hook and the cover hook are in place, the lock tongue passes through the through hole and enters the second slide groove, providing secondary fixation for the lock body. When unlocking is required, the electric push rod, which is electrically connected to the intelligent control module, drives the slide rod to move towards the cover hook after receiving the information matching signal. The compression spring structure causes the lock tongue to enter the through hole. At the same time, the lock hook is driven to rotate by the servo motor, which pulls the lock tongue out of the through hole and separates it along the first slide groove.

[0024] In this embodiment, the intelligent control module 6 adopts a fingerprint recognition module, which unlocks the storage box by fingerprint verification. The fingerprint sensor is exposed on the surface of the box. The status feedback module 7 includes an LED indicator 71 and a buzzer 72 set on the surface of the box. The LED indicator is set to two sets, a red indicator and a green indicator, which correspond to the locked and opened states of the storage box, respectively. The LED indicator and the buzzer indicate the locked state. When three consecutive incorrect fingerprints or external force prying are detected, the buzzer sounds continuously and sends an alarm to the vehicle system, realizing the alarm is triggered when abnormal operation occurs.

[0025] The surface of the housing 1 corresponding to the pivot 12 is provided with an emergency mechanical keyhole 8 with a built-in hidden key slot, which is used for unlocking in case of power failure. The lock hook can be manually turned by the mechanical key. The surface of the emergency mechanical keyhole 8 is provided with a movable cover to prevent debris from entering and blocking the keyhole.

[0026] The difference between Embodiment 2 and Embodiment 1 is that the intelligent control module adopts a Bluetooth or NFC module, and the fingerprint recognition device is replaced by a Bluetooth transmission module or an NFC sensing module. The Bluetooth transmission module or NFC sensing module is hidden in the interlayer, supporting wireless control of mobile phones or vehicle systems.

[0027] How this application works:

[0028] Locking: When the lock hook abuts against the second limit block, the storage box lid closes. The lid hook compresses the elastic plate and abuts against the detection contact. The resulting locking signal drives the servo motor to rotate the lock hook counterclockwise until it abuts against the first limit block and the lid hook contact surface. The servo motor then locks the lock hook. During the rotation of the lock hook, the electric push rod simultaneously pushes the slide rod out of the second slide groove, exposing two sets of through holes. When the lock hook and the lid hook are in contact, the lock tongue enters the second slide groove from the through hole. The pressure sensor on the spring structure detects the position. Once in position, a signal is triggered, and the red LED indicator light illuminates, completing the locking.

[0029] Unlocking: After successful fingerprint verification / Bluetooth signal matching / NFC signal matching, the electric push rod retracts, and the end of the slide rod with the rounded head moves towards the cover hook, pressing the rounded bolt in the second slide groove into the through hole. The servo motor drives the lock hook to rotate clockwise to the second limit block. During the rotation of the lock hook, the bolt exits from the bottom chamfer of the through hole and slides along the first slide groove until it separates from the lock hook. The cover hook rebounds away from the box body through the elastic structure at the rotating part of the box cover, and the green LED indicator light illuminates, completing the unlocking process.

[0030] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections.
