Problems solved by technology
[0004] In the prior art, the lock body bracket and the steering column seat of the electronic steering column lock are an integral structure. In order to withstand large twisting forces without damage, they are generally metal die-casting parts. However, the lock body bracket is used as an electronic steering column lock. The main carrier of the parts of the column locking device has a complex structure, which leads to a complex mold structure of the die-casting lock body bracket. In this way, in industrial production, the product defect rate is relatively high, processing is difficult, and the manufacturing cost is increased. At the same time, the electronic steering column lock Because the whole device is a metal die-casting part, its weight is too heavy, and it will cause a lot of inconvenience during transportation
[0005] The diameters of existing vehicle steering column columns are different, and the common ones are divided into two diameters of 45mm and 48.8mm, but because the lock body bracket and steering column seat of the electronic steering column lock in the prior art are an integral
During production, it is necessary to make molds for the entire steering column lock structure for different steering column diameters, which increases the cost, and if the structure of the lock body bracket is partially changed in subsequent improvements, the entire mold needs to be remade , also increases the cost of improving

Abstract
The invention relates to an electronic locking device of a vehicle steering system, and in particular to a base of an electronic locking device of the vehicle steering system as well as an installation method of the base. The invention aims to provide a base of an electronic steering column locking device and an installation of the base. The base adopts a split structure, is simple in structure, light in weight, easy to improve, low in manufacturing cost, and simple in installation. The base of the electronic steering column locking device comprises a steering column seat and a lock body bracket, wherein the lock body bracket is provided with a mounting bracket for mounting a motor, a worm, a bevel wheel, a guide rod, a PCB (Printed Circuit Board) and a locking block; the lock body bracket is fixed to the steering column seat.
Description
technical field [0001] The invention relates to an electronic locking device of a steering system of a motor vehicle, in particular to a base of an electronic locking device of a steering system of a motor vehicle and an installation method thereof. Background technique [0002] The electronic steering column lock (Electronic Steering Column Lock, ESCL) device is a device used to lock the steering system of a motor vehicle, and is a safety component for realizing anti-theft measures for motor vehicles. [0003] The electronic steering column lock controls the internal motor to drive the mechanical rotating structure to complete the locking and unlocking actions according to external signals (such as driver's driving commands, etc.). Among them, the common mechanical transmission structures are divided into: gear transmission, worm gear transmission, screw transmission, cam structure transmission, linkage transmission and so on. In the prior art, the end of the transmission ...
