Abstract

The invention discloses a rapid-locking mechanism of a vehicle-mounted terminal. The rapid-locking mechanism comprises a first shell, a second shell matched with the first shell and a locking part, acavity is formed between the first shell and the second shell and used for containing the vehicle-mounted terminal, inlets are formed in one end of the first shell and one end of the second shell, wherein the vehicle-mounted terminal is inserted into the inlets, a ratchet wheel and a pawl matched with the ratchet wheel are arranged on the first shell, a first retainer spring matched with the pawlis further arranged on the first shell, the locking part comprises a fixing plate, an insertion pin, an insertion plate and a locking plate are arranged at the bottom of the fixing plate, a gear rackmatched with the ratchet wheel is arranged on the locking plate, the insertion pin is matched with an installation hole in the vehicle-mounted terminal, a second retainer spring matched with the insertion plate is arranged on the first shell, and an unlocking button matched with the pawl is further arranged on the first shell. With the rapid-locking mechanism, the problems that in the prior art, screws are adopted for fastening the vehicle-mounted terminal, so that detaching and installing are complex in operation, and efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical assembly, in particular to a quick lock mechanism for a vehicle-mounted terminal. Background technique [0002] The vehicle-mounted terminal is the front-end device of the vehicle monitoring and management system, and it can also be called the vehicle dispatching and monitoring terminal (TCU terminal). The vehicle-mounted terminal is one of the essential components of the vehicle. [0003] The connection method between the vehicle-mounted terminal and the vehicle affects the convenience of installation and disassembly of the vehicle-mounted terminal. The installation of the existing vehicle-mounted terminal is fastened with screws, and it needs to be assembled and disassembled with a tool screwdriver for fastening and loosening, which does not have a fast and convenient method. characteristics, and does not meet the requirements of rapid assembly and disassembly during wartime, the efficiency i...
