Problems solved by technology

This type of housing fastener has disadvantages: on the one hand, welding, buckle, screw, etc. are non-removable or can only be disassembled for a limited number of times, making maintenance difficult and costly. If one of the small parts is damaged, the entire battery must be replaced. control unit, resulting in waste; on the other hand, the separate structure of the positioning structure and the locking structure causes a waste of mechanical design space, which is contrary to the current trend of lightweight and energy-saving automobiles

Abstract

The invention provides a locking device and a shell with the locking device. The locking device comprises a sliding lock and an interlocking assembly, wherein the interlocking assembly includes a first locking element and a second locking element; the axial opposite surfaces of the first locking element and the second locking element are respectively provided with a positioning rib and a positioning groove; the radial opposite surfaces of the first locking element and the second locking element are respectively provided with a first locking groove and a second locking groove; when the first locking element and the second locking element are assembled together, the positioning rib and the positioning groove are mutually matched to limit the radial displacement of the interlocking assembly; the first locking groove and the second locking groove are spliced to form a locking cavity, the axial displacement of the interlocking assembly is limited when the sliding lock is inserted into the locking cavity, thereby fixing and locking an interlocking device. The locking device realizes the fixing and locking functions through the above configuration. Meanwhile, the locking device has the advantages of simple structure, small occupied space, easy disassembly, convenient maintenance and low maintenance cost.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a locking device and a casing with the locking device. Background technique [0002] In recent years, with the rapid growth of social economy, China's car ownership is getting higher and higher. With the development of automobile technology and the substantial increase in the number of automobiles, people have put forward higher and higher requirements for the intelligence and electronics of automobiles. Traditional mechanical parts and accessories in automobiles are gradually replaced by electronic parts and accessories. [0003] In order to drive and control the car more conveniently, safely and comfortably, and use the interior space of the car, the car is equipped with multiple electronic control units. In order to protect the electronic components inside the casing, the casings need to be well positioned and locked to avoid dust entry and vibration damage. [0004] The existing sh...
