Description

A motor vehicle lock with a connecting rod structure to prevent motor stalling Technical Field

[0001] The invention relates to a caravan lock, in particular to a caravan lock with a connecting rod structure to prevent motor stalling. Background Art

[0002] Currently, the global RV market continues to expand, resulting in strong market demand. In addition to traditional mechanical locks, as electronic technology continues to mature, smart RV locks and high-tech products are gradually being accepted by the market. At the same time, with the development and popularization of intelligent technology, smart RV locks will become increasingly intelligent in the future. Smart door locks generally use a variety of methods such as passwords, fingerprints, and facial recognition to open, and functions such as automatic unlocking are gradually becoming a trend, which can effectively enhance the user experience. For example, the invention disclosed in the Chinese patent document is application number 202110934901.8, the authorization announcement date is 2022.06.14, and the invention name is "A waterproof and shockproof electronic smart RV lock." The first locking structure of the RV lock includes an outer handle, a first lock core assembly mounted on the outer handle, and a switch lock tongue; the switch lock tongue is mounted in the mounting cavity, the outer handle is mounted on the front of the base, and the outer handle and the inner handle control the opening and closing of the switch lock tongue; the second locking structure includes a second lock core assembly, a safety lock tongue, a connecting assembly, and an electronic locking device; the safety lock tongue and the connecting assembly are arranged in the mounting cavity, the unlocking knob is mounted on the back of the inner plate, the connecting assembly connects the second lock core assembly, the safety lock tongue, and the unlocking knob, and the unlocking knob and the second lock core assembly control the opening and closing of the safety lock tongue through the connecting assembly; the worm gear drives the connecting sleeve to rotate through static friction, which is converted into linear motion of the safety lock tongue. However, the above-mentioned product and similar products have an anti-slip friction structure to prevent the lock tongue from retracting after unlocking, a connecting rod structure to prevent the lock tongue from retracting after unlocking, and an unlocking method for both internal and external unlocking, which all belong to existing conventional technologies. Meanwhile, some RV locks currently utilize a hasp lock mechanism. There are two main types of hasp locks on the market: 1. A friction-driven locking mechanism, where spring pressure drives a connecting rod. This friction-driven mechanism consumes significant power; 2. A dual-link mechanism achieves a locked position, allowing for opening and closing. Both of these unlocking methods suffer from complex structures and difficulty controlling frictional drag. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the present invention aims to provide a motor-stall-proof linkage-structured RV lock. This solution addresses the technical issues of existing similar products, such as the relatively simple clutch mechanism, the lack of a brake structure, and the lack of a geared clutch mechanism. Furthermore, the worm clutch mechanism suffers from a suboptimal friction structure between the worm wheel and worm, resulting in a complex structure, inconvenient production and assembly, and high power consumption during unlocking.
