[0023] See also Figure 1-5 , a technical solution provided by the utility model:

[0024] Example 1:

[0025] A detection mechanism for a power steering controller includes a detection bracket 1, an electric slide rail 2 is installed inside the detection bracket 1, the output end of the electric slide rail 2 is fixedly connected to a base 3, the top of the base 3 is fixedly connected to a seat 4, a cross bar 5 is slidably installed on the inner wall of the detection bracket 1, a stabilizing component 6 is slidably installed on the outer wall of the cross bar 5, a turntable 7 is installed on one side of the detection bracket 1, a mounting frame 8 is fixedly connected to the top of the turntable 7, a push block 9 is fixedly connected to the outer wall of the turntable 7, a ranging rod 10 is slidably installed on one side of the detection bracket 1, and a simulation component 11 is installed on the top of the detection bracket 1.

[0026] The above structure uses the simulation component 11 on the detection bracket 1 and the pressure spring 1101 to simulate the steering pressure encountered by the steering wheel during the left and right steering process, thereby simulating the steering angle of the steering wheel with or without road pressure. In addition, the pin 1103 is passed through the push plate 1102 to the position of the limit hole above the detection bracket 1 to simulate flat road conditions. Release the push plate 1102 to simulate the pressure state, making the device more practical.

[0027] Furthermore, the interior of the stabilization component 6 includes a limiter 601, a limit block 602, a movable bracket 603, an electric push rod 604, a connecting rod 605, a limit cover 606, a linkage disk 607 and a steering angle detector 608. The outer wall of the cross bar 5 is provided with a limiter 601, the outer wall of the limiter 601 is fixedly connected to the limit block 602, the outer wall rotation shaft of the limit block 602 is connected to the movable bracket 603, one end of the movable bracket 603 is fixedly connected to the electric push rod 604, the output end rotation shaft of the electric push rod 604 is connected to the connecting rod 605, the other end of the connecting rod 605 is fixedly connected to the limit cover 606, the inner wall of the limit cover 606 is slidably installed with a linkage disk 607, and the top of the linkage disk 607 is fixedly connected to the steering angle detector 608.

[0028] The above structure stabilizes and limits the main frame of the power controller through the stabilizing component 6. During the detection process, the steering angle is monitored by the steering angle detector 608, and the position is corrected by the scale on the outer wall of the limit cover 606 and the groove on the linkage plate 607, which can intuitively show the left and right rotation angle deviation of the steering wheel.

[0029] Furthermore, the limiter 601 is divided into a sleeve and a bolt, and the groove of the limit block 602 has an inclined angle with the detection bracket 1, the movable bracket 603 and the electric push rod 604 are perpendicular to each other, the diameter of the limit cover 606 expands from top to bottom, the bottom of the linkage disk 607 is set as a suction cup, the outer wall of the limit cover 606 is set with a scale, and grooves are symmetrically set on both sides of the return position of the linkage disk 607.

[0030] The above structure can fix the steering wheel through the suction cup, and it can rotate normally during the detection process.

[0031] Furthermore, the interior of the simulation component 11 includes a pressure spring 1101, a push plate 1102 and a latch 1103. The inner wall of the detection bracket 1 is fixedly connected to the pressure spring 1101, and the other end of the pressure spring 1101 is fixedly connected to the push plate 1102. A latch 1103 is provided on one side of the push plate 1102. A limiting hole is provided on the top of the detection bracket 1, and the latch 1103 corresponds to the limiting hole. The simulation component 11 is located on both sides of the turntable 7.

[0032] The above structure can simulate the steering pressure of road conditions in two different states through the limitation of the latch 1103.

[0033] Furthermore, the ranging rod 10 is located in front of the push block 9, and several push blocks 9 correspond to the ranging rod 10, and the ranging rod 10 slides along the slot on one side of the detection bracket 1, and the top of the mounting frame 8 is provided with a bolt and a sleeve.

[0034] The above structure drives the push block 9 to rotate by rotating, and pushes the ranging rod 10 outward. By monitoring the extended length of the ranging rod 10 and observing the left and right steering difference, adjustment can be made.

[0035] Working principle: When in use, first, the seat 4 and the stabilizing component 6 can both be adjusted in position. The electric slide rail 2 can drive the seat 4 to adjust its front and rear position. The detection mechanism can be adjusted according to the user's habits during the detection process to reduce the impact of human operation. The stabilizing component 6 is provided to stabilize the position of the steering frame at the bottom of the power steering controller, and the limiter 601 is used to limit the steering column at the bottom of the steering wheel. The limit cover 606 is aligned with the steering wheel and buckled. The internal suction cup of the linkage plate 607 is used to fix it. While keeping the bottom stable, the steering wheel can be rotated normally.

[0036] Secondly, during the detection process, the steering angle is monitored using the steering angle detector 608, and the position is corrected using the scale on the outer wall of the limit cover 606 and the groove on the linkage plate 607. This can intuitively show the left and right rotation angle deviation of the steering wheel. At the same time, when the steering wheel rotates, the steering wheel is driven to steer. The steering gear is connected to the mounting frame 8, and the steering angle is simulated using the turntable 7. The push block 9 is rotated by rotation, and the distance measuring rod 10 is extrapolated. By monitoring the extended length of the distance measuring rod 10, the left and right steering difference is observed, and adjustments can be made.

[0037] Finally, the simulation component 11 set on the detection bracket 1 uses a pressure spring 1101 to simulate the steering pressure encountered by the steering wheel during left and right steering, thereby simulating the steering angle of the steering wheel with or without road pressure. In addition, the pin 1103 is passed through the push plate 1102 to the position of the limit hole above the detection bracket 1 to simulate flat road conditions. Loosening the push plate 1102 can simulate the pressure state, making the device more practical.
