Description

Technical Field

[0001] This utility model relates to the field of automotive electromechanical locking equipment technology, and in particular to an electromechanical integrated secondary opening central locking mechanism. Background Technology

[0002] With the rapid development of the automotive industry, consumers' demands for vehicle safety, convenience, and intelligence are increasing. As a core component ensuring driving safety and user experience, the completeness of the vehicle's functions and its adaptability have become important indicators for measuring vehicle quality. Currently, traditional vehicle locking mechanisms on the market generally suffer from problems such as limited functionality, insufficient expandability, and limited adaptability to different scenarios. Most products can only achieve basic locking and unlocking functions and lack the ability to respond to complex usage scenarios. In family car scenarios, they are unable to meet the needs of child safety and emergency escape, and in commercial vehicles, they cannot meet the requirements of intelligent control and status visualization. At the same time, traditional mechanisms mostly adopt an integrated structural design, which requires overall redevelopment to adapt to different vehicle models or user needs, resulting in long R&D cycles, high costs, and difficulty in quickly responding to diverse market demands.

[0003] Against this backdrop, the secondary-opening central locking mechanism was developed. As a new mechatronic product integrating mechanical structure and electronic control technology, its core design concept lies in achieving flexible functional expansion and efficient adaptation through a modular architecture. Specifically, the product standardizes the core locking execution module, sensor detection module, electronic control module, and functional expansion interface. Each module can operate independently or work collaboratively through a unified interface. The basic functional modules ensure locking reliability and ease of operation during daily vehicle use, covering full locking, semi-locking, internal or external opening, internal locking or unlocking, and external locking. The core functions include unlocking, preventing accidental locking, and indicating lock / unlock and lock / open signals. The extended function modules are specially developed for diverse scenarios. The secondary internal opening function effectively prevents the risk of children or accidental touches from opening the car from inside through dual operation logic. The tension lock function can automatically trigger rapid unlocking in the event of a collision, ensuring that the escape route for passengers is unobstructed. The self-closing lock function enables the door to automatically lock after being lightly closed, improving the convenience of operation and the sealing of the door. The electric unlocking function supports remote control or linkage with intelligent interaction systems, adapting to the development trend of intelligent vehicles. Utility Model Content

The opening connecting buckle 17 is installed on the external opening arm 16 and is connected to the customer's external handle via a pull rod or pull cable. The opening connecting arm 18 is a lever structure, with one end connected to the external opening arm 16 and the other end connected to the internal opening arm 23, realizing the internal / external opening of the locking mechanism. The locking / unlocking mechanism 15 is divided into an electrically controlled locking / unlocking mechanism and a mechanical external locking / unlocking mechanism. The electrically controlled locking / unlocking mechanism includes a motor, a worm gear, and a worm wheel. The worm gear is connected to the motor shaft through a D-slot. When the motor is energized, it drives the worm gear to rotate. The worm gear drives the worm wheel through tooth meshing, which realizes the electric locking and unlocking functions of the locking mechanism. Also known as an electronically controlled lock, the mechanical external locking and unlocking mechanism includes an external locking arm 19 and an external locking connecting buckle 20.

The internal opening arm 23 is connected to the customer's internal handle via a pull cable. The locking mechanism can be opened by pulling twice, i.e., the secondary opening function. The internal locking and unlocking mechanism 22 includes an internal locking arm 25 and an eccentric torsion spring 26. It realizes the internal locking and unlocking function by connecting to the safety arm on the fixed base assembly 2. Furthermore, with the car locking mechanism in the closed and locked state, the inner opening arm 23 is connected to the inner handle via a cable, and the inner locking arm 25 is in the locked position. Figure 2 When the inner handle is pulled to open, the inner opening arm 23 rotates, and the flanged boss 27 pushes the inner locking arm 25, causing the inner locking arm 25 to move to the unlocked position. Figure 3 After releasing the inner handle, pull the inner handle again to open it. The inner opening arm 23 pushes the opening mechanism to open the locking mechanism. That is, pulling the inner opening arm 23 once moves the car locking mechanism from the locked position to the unlocked position. Pulling the inner opening arm 23 a second time moves the inner opening arm 23 directly to the open position, realizing the secondary inner opening function of the car locking mechanism.
