[0002] The accuracy and speed of the steering response of a car's steering gear directly affect the driving safety of drivers and passengers, and sensors are important components that affect the above two factors.

[0003] After searching, the Chinese patent authorization announcement number CN219714422U discloses a steering gear sensor quick positioning mechanism, including a base plate, a pillar, a sliding assembly, an L-shaped mounting plate, a sensor positioning block, a bracket, and a quick plug-in pin. The sliding assembly is installed on the base plate with a pillar, and the movable end of the sliding assembly is connected to the bottom of the long side of the L-shaped mounting plate. The sensor positioning block is installed at the end of the long side of the L-shaped mounting plate. The quick plug-in pin is installed on the base plate with a bracket, and the quick plug-in pin is inserted into the short side of the L-shaped mounting plate or separated from the short side. Compared with the prior art, the utility model designs a steering gear sensor quick positioning mechanism, which can achieve rapid positioning in specific workstations such as space limitations, avoid the problem of swinging and rotation of the steering gear sensor during the performance test process affecting the quality of product performance, and meet the performance test requirements. The utility model has the advantages of low price and easy operation.

[0004] However, although the above-mentioned patent can avoid the problem of rotation and deflection of the steering gear sensor during testing, the L-shaped plate provided therein needs to be manually driven to reset after the steering gear sensor is released from its position, which is relatively inconvenient in overall operation and requires repeated pulling of the handle latch and sliding of the L-shaped plate to release the steering gear sensor; the latch device provided therein uses friction to fix the L-shaped plate, but the fixing effect of the L-shaped plate by relying on friction is relatively poor.

The sensor 9 is positioned by using the sensor positioning block 7 in conjunction with the positioning lug 8, and the L-shaped plate body 4 is fixed by using the socket 51 and the fixing rod 57.

[0057] After the sensor 9 is positioned, when the sensor 9 does not need to be positioned for use in the future, the pull handle 53 can be used to apply an upward force to the pull rod 52, and the force acts on the compression spring 55 to move the fixing rod 57 upward, and after being separated from the inside of the insertion hole 51, the reset spring 35 restores the deformation and applies a reverse force to the L-shaped plate body 4, so that the L-shaped plate body 4 can be reset to its original position autonomously;

[0058] This solution saves time and effort, is conducive to subsequent positioning use, meets usage needs, and improves usage effects
