Technical Field
[0001] The utility model relates to the technical field of seat belts, in particular to an intelligent unlocking seat belt buckle assembly based on temperature and voice signals. Background Art
[0002] As a primary means of transportation in modern times, automobile safety remains a key concern. Seatbelts, essential equipment for protecting drivers and passengers, play a crucial role in minimizing injuries in various traffic accidents, effectively reducing the risk of casualties. Traditional seatbelt buckles rely on manual unlocking. Under normal circumstances, drivers can easily release the seatbelt by pressing a button.
[0003] However, when a vehicle encounters an unexpected situation, such as a fire or a battery short-circuit fire after a collision, the temperature inside the vehicle can rise dramatically in a short period of time. Traditional manual seatbelt release buckles face numerous challenges. For example, in an emergency, drivers and passengers may be unable to accurately and forcefully operate the manual release button immediately due to panic or physical injuries. Heat-release seatbelts can be combined with voice control and intelligent seatbelt release, enabling both manual and automatic release. Statistics show that many casualties in accidents involving vehicle fires are related to the inability to release seatbelts in a timely manner, highlighting the limitations of traditional manual release seatbelt buckles in extreme heat conditions.

[0033] The working principle of this utility model:
[0034] Locking principle of buckle 1: When fastening the seat belt, insert the lock tongue of the seat belt into the lock body assembly 12 from the socket of buckle 1. The downward insertion of the lock tongue will push the slide 127. The slide 127 slides downward through the hook plate 124, driving the spring 123 to bend. Under the elastic force of the spring 123, the hook plate 124 rotates. The hook plate 124 pushes the pin 126 to slide to the top of the slide groove 125, allowing the lock hook 128 to pass through the opening on the lock tongue and enter the fixed lock hole 129, thereby locking the seat belt.
[0035] Principle of manual unlocking of buckle 1: Press button switch 13, which presses pin 126 downward through levers 14 on both sides. Pin 126 slides to the bottom of slot 125, and hook plate 124 rotates under force, driving slide 127 to rise while lock hook 128 returns to its original position, completing manual unlocking.
[0036] The intelligent unlocking principle of buckle 1: the acquisition module collects the temperature, voice, and ECU signals received by the temperature sensor 24, microphone 210, and vehicle ECU (electronic control unit). The processing module processes, outputs, and makes decisions on the collected temperature, voice, and ECU signals. Then, the drive module controls the motor 25 to drive the recovery disk 26 to tighten the thin rope 27, thereby pulling the button switch 13 through the thin rope 27 to open the buckle 1.
[0037] It should be noted that in the drawings provided by the present invention, the buckle 1 is in a locked state.
[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
