Description

Technical Field

[0001] This invention belongs to the field of lock technology, specifically relating to an integrated smart electronically controlled titanium wire lock and combination lock. Background Technology

[0002] Currently, intelligent electronic locks have become a mainstream component in two-wheeled electric vehicles, motorcycles, toolboxes, logistics boxes, power distribution cabinets, and various light-duty enclosed equipment, used to achieve functions such as automatic locking, electronic unlocking, and security against theft. Existing intelligent electronic locks on the market generally use electromagnet drive structures or micro-motor drive structures as their core actuators. Their working principle is to use electromagnetic attraction or motor gear transmission to drive the lock tongue and lock hook to complete the locking and unlocking actions.

[0003] In long-term use and mass application, these traditional electric locks have complex structures and numerous parts. Traditional electric locks require components such as electromagnet coils, iron cores, return springs, gear sets, reduction mechanisms, and transmission linkages. The overall structure is cumbersome, requires high processing precision, and has complex assembly processes, which directly leads to high manufacturing costs and is not conducive to large-scale popularization and application. Electromagnets and motors require continuous power supply to maintain operation, resulting in high operating current and high energy consumption. Long-term operation can easily lead to faults such as coil overheating, burnout, and jamming. In environments such as low temperature, humidity, and water exposure, the insulation performance deteriorates, making it prone to failure and insufficient stability. Therefore, it is necessary to design an integrated smart electronically controlled titanium wire lock and combination lock to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated smart electronically controlled titanium wire lock and combination lock to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated smart electronically controlled titanium wire lock and combination lock, comprising a base, a cover plate, a titanium wire drive assembly, a bolt mechanism, a combination lock assembly, and a micro switch; The titanium wire drive assembly includes a titanium wire, titanium wire terminal A, titanium wire terminal B, a connecting block, a fixing block, a resistor, and a ceramic ring; the two ends of the titanium wire are fixed to the connecting block and the fixing block respectively through titanium wire terminal A and titanium wire terminal B, the titanium wire passes around the ceramic ring, and the resistor is connected in series in the power supply circuit of the titanium wire; The locking mechanism includes a locking hook, a locking hook spring, a locking tongue, and a locking tongue spring; the locking hook is linked with the connecting block, the locking hook spring provides a restoring force, the locking tongue can spring back to its original position under the action of the locking tongue spring, and the locking tongue can be pressed down to lock freely when locked; The combination lock assembly is connected to the connecting block via a pull wire, enabling mechanical emergency unlocking; The micro switch is located on the movement path of the locking tongue. When the locking tongue is unlocked to the position, the micro switch is triggered and the power supply is cut off.

[0006] Preferably, the titanium wire is made of shape memory alloy, which shrinks when heated by electricity and returns to its original length when cooled by power-off, and is used to drive the lock hook to complete the unlocking action.

[0007] Preferably, the power supply voltage is compatible with multiple specifications such as DC1.5V, 3V, 5V, 12V, and 24V, and can be compatible with different power systems without changing the core structure.

[0008] Preferably, the electronic unlocking and the password mechanical unlocking are two independent drive paths, and either mode can be used to unlock independently without interfering with each other.

[0009] Preferably, when unlocking, the locking tongue triggers a micro switch to provide an unlocking signal feedback and automatically disconnect the power supply to the titanium wire, thus forming an energy-saving and protection mechanism.

[0010] Preferably, the locking method is a purely mechanical pressing type, where the bolt can be directly pressed down on the locking tongue to automatically engage and lock, without the need for electricity or additional operation.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention eliminates the complex components of traditional locks, such as electromagnets, coils, motors, gear sets, and reduction mechanisms. It consists of only a few parts, such as titanium wire drive components, lock hooks, lock tongues, combination locks, and micro switches. The overall structure is simplified, the processing precision requirements are low, the assembly process is few, the yield rate is high, the raw material cost and manufacturing cost are reduced, and it is suitable for mass production.

[0012] 2. Using shape memory alloy titanium wire as the driving element, it generates a very small current when it is heated and contracted instantaneously upon power-on, requiring no continuous power supply. Its operating current is lower than that of electromagnets and motors, resulting in low heat generation, no coil burnout, and no jamming. Combined with a micro-switch automatic power-off design, it further avoids unnecessary power consumption and extends the power supply's lifespan, making it suitable for low-power applications such as electric vehicles and battery-powered boxes.

[0013] 3. The titanium wire drive assembly can be easily adjusted to adapt to a full range of DC 1.5V / 3V / 5V / 12V / 24V voltages. It can be compatible with different equipment power systems without changing the core structure. It is suitable for a variety of equipment such as two-wheeled electric vehicles, motorcycles, logistics boxes, toolboxes, storage cabinets, and power distribution cabinets. It is versatile, highly interchangeable, and reduces the R&D costs of enterprises for multiple specifications.

[0014] 4. This invention has two independent unlocking methods: electronic intelligent unlocking and password mechanical backup unlocking. When the power supply is normal, the electronic unlocking is fast, convenient and efficient. When the vehicle is powered off, the power is exhausted, or there is a circuit fault, the lock can be opened mechanically in an emergency without relying on electricity, avoiding the risk of being locked out and unusable, thus improving security and availability.

[0016] 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, and 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.

[0017] Please see Figures 1 to 2 The present invention provides a technical solution: an integrated smart electronic control titanium wire lock and combination lock box lock, the whole body is composed of a base 1 and a cover plate 16 forming the outer shell, and the titanium wire drive assembly, the lock tongue mechanism, the combination lock assembly and the micro switch 19 are installed inside.

[0018] One end of the shape memory alloy titanium wire 12 is fixed to the connecting block 2 through titanium wire terminal A7, and the other end is fixed to the fixing block 13 through titanium wire terminal B11; the titanium wire 12 passes around the ceramic ring 18 to avoid friction damage; the resistor 15 is connected in series in the power supply circuit of the titanium wire 12 through the resistor terminal 14 to limit the current and protect the titanium wire 12; the wire terminal 5 is used to connect to an external DC 1.5V-24V power supply.

[0019] The locking hook 3 is rotatably mounted on the base 1 and is linked with the connecting block 2; one end of the locking hook spring 6 abuts against the locking hook 3 and the other end abuts against the base 1, and is used to drive the locking hook 3 to reset after power failure; the locking tongue 8 is slidably mounted in the base 1, and the locking tongue spring 9 is located below the locking tongue 8 to provide reset elasticity; when locking, the external bolt can directly press down on the locking tongue 8 to achieve automatic locking.

[0020] The combination lock 20 is fixed on the base 1 or the outer casing. The actuator of the combination lock 20 is connected to the connecting block 2 via the pull wire 21. When the correct password is entered and the button is pressed, the pull wire 21 pulls the connecting block 2 to move, realizing a purely mechanical emergency unlocking.

[0021] The micro switch 19 is fixed on the base 1 and located below the movement path of the locking tongue 8. When the locking tongue 8 is unlocked and springs back into place, it presses down to activate the micro switch 19. The micro switch 19 outputs an unlocking feedback signal and controls the drive circuit to immediately cut off the power supply to the titanium wire 12.

[0022] The electric unlocking process involves external power supply through wire terminal 5 → titanium wire 12 is energized and heated to rapidly retract → pulling the connecting block 2 to move → driving the lock hook 3 to rotate and release the lock tongue 8 → the lock tongue 8 rebounds under the action of the lock tongue spring 9 to complete the unlocking → the lock tongue 8 presses down the micro switch 19 → the system receives a feedback signal and immediately cuts off the power → titanium wire 12 cools down and returns to its original length → the lock hook spring 6 drives the lock hook 3 to reset, waiting for the next locking.

[0023] When the vehicle loses power, experiences a wiring fault, or the control system fails, the emergency unlocking process involves operating the combination lock 20, entering the correct password, and pressing the execute button. This pulls the cable 21, causing the connecting block 2 to move, which in turn drives the lock hook 3 to rotate. The lock tongue 8 then rebounds under the action of the lock tongue spring 9, unlocking the vehicle and achieving purely mechanical emergency unlocking.

[0024] The locking process does not require electricity. Simply press the external bolt down on the latch 8 → the latch 8 moves down against the spring force of the latch spring 9 → the lock hook 3 is engaged in the slot of the latch 8 under the action of the lock hook spring 6 → automatic locking is completed, and the operation is simple and quick.

[0025] This invention integrates titanium wire electronic drive with password mechanical unlocking, while maintaining low power consumption, high reliability, and long lifespan. It solves the problems of complex structure, high power consumption, easy failure, and inability to unlock when a single titanium wire lock is out of power. It is suitable for various scenarios such as vehicles and boxes, and has high practical value and market prospects.
