[0002] With the rapid development of the automobile industry and the continuous improvement of people's living conditions, cars have become one of the indispensable means of transportation for people to travel. In order to improve people's riding experience, cars are now equipped with air conditioners. Therefore, air outlets are generally installed on the center console of cars now, and each air outlet is equipped with blades for changing the direction and amount of air outlet.

[0003] In order to ensure the control of air outlet direction and air volume, the blades in the air outlet of each car must be inspected to ensure that the number and position of the blades are installed accurately.

[0004] The existing method of blade inspection is usually manual inspection, but manual inspection is inefficient and has poor detection accuracy, so it is impossible to accurately control the quality of the car. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle center console air outlet blade detection device and method, which can improve the detection efficiency and detection accuracy of the air outlet blades.

[0015] Further, the mounting bracket includes four cylinder mounting columns, which are arranged in a rectangular shape, and have two mutually parallel first reinforcing beams installed at their upper ends, and four second reinforcing beams installed at their lower ends, and all the cylinder mounting columns are connected in pairs through all the second reinforcing beams;

[0016] A horizontal cylinder mounting crossbeam and a horizontal cylinder fixing plate parallel to each other are installed in the middle of all the cylinder mounting columns, and the horizontal cylinder mounting crossbeam and the horizontal cylinder fixing plate are perpendicular to the first reinforcement crossbeam;

[0017] One end of the horizontal cylinder is fixedly installed in the middle of the horizontal cylinder mounting beam, and the other end is fixedly installed in the middle of the horizontal cylinder fixing plate. After the end of the horizontal piston rod passes through the horizontal cylinder fixing plate, a horizontal cylinder end connecting plate is installed.

[0018] Furthermore, horizontal guide rods parallel to the horizontal piston rod are respectively provided on both sides of the horizontal piston rod. After the horizontal guide rods pass through the horizontal cylinder fixing plate, they are fixedly connected to the horizontal cylinder end connecting plate.

[0019] Furthermore, the horizontal cylinder end connecting plate is fixedly connected to the vertical cylinder, the end of the vertical piston rod is equipped with a vertical cylinder end connecting plate, and the vertical cylinder end connecting plate is fixedly connected to the middle of the first sensor mounting cross bar;

[0020] Vertical guide rods parallel to the vertical piston rod are respectively arranged on both sides of the vertical piston rod.

[0022] The horizontal cylinder end connection plate is connected to one end of a horizontal drag chain, and the other end of the horizontal drag chain is connected to the mounting bracket.

[0023] The key to the vehicle center console air outlet blade detection method is to include the following steps:

[0024] S1: The horizontal cylinder, the vertical cylinder, the two first laser displacement sensors, the camera, and the four second laser displacement sensors are all connected to the processor.

[0025] S2: The processor controls the horizontal piston rod to extend, driving the vertical piston rod and the sensor mounting bracket to reach the top of the center console air outlet;

[0026] S3: The processor controls the vertical piston rod to extend, the sensor mounting bracket to descend, the two first laser displacement sensors and the camera are located on the left side of the air outlet of the vehicle center console, and face the left and right sweeping blades in the air outlet, and the four second laser displacement sensors are located on the right side of the air outlet of the center console, and face the upper and lower sweeping blades in the air outlet;

[0027] S4: The processor controls the two first laser displacement sensors to aim at the middle of the left and right wind sweep blades to emit horizontal laser signals, the two second laser displacement sensors to aim at the upper part of the upper and lower wind sweep blades to emit laser signals, and the other two second laser displacement sensors to aim at the lower part of the upper and lower wind sweep blades to emit laser signals, and sends the reflected left and right wind sweep blade detection signals and the upper and lower wind sweep blade detection signals to the processor; at the same time, when the first laser displacement sensor and the second laser displacement sensor emit lasers, the camera starts to record the blade detection video;

[0028] S5: The processor determines whether the air outlet blades are qualified;

[0029] If the left and right sweep blade detection signals are within the ±5% range of the left and right sweep blade standard detection signals, and the upper and lower sweep blade detection signals are within the ±5% range of the left and right sweep blade standard detection signals, the outlet blade detection is qualified;

[0030] Otherwise, it is unqualified;

[0031] S6: The processor saves the left and right wind sweeping blade detection signals, the upper and lower wind sweeping blade detection signals, the detection results and the blade detection video.

[0032] The laser displacement sensor emits laser to any point on the blade and receives the laser reflection signal. The laser reflection signal value corresponds one-to-one with the distance between any point on the blade and the laser displacement sensor, thereby determining whether the blade rotation angle range meets the factory requirements.

[0033] The start and end of camera recording are controlled by the processor. After the processor starts the detection program, it also controls the camera to start recording video. After the blade detection is completed, the end recording command is sent and the camera stops recording the blade detection video, thereby reducing video memory and facilitating long-term video storage. At the same time, the video is named and saved according to the barcode information of the tested center console. Each center console barcode is unique, which makes it convenient to find the corresponding center console detection video according to the center console barcode in the later stage, thereby facilitating quality traceability.

[0034] Beneficial effects: 1. The vehicle center console air outlet blade detection device can improve the detection efficiency and detection accuracy of the air outlet blades.

[0035] 2. The laser displacement sensor emits laser to any point on the blade and receives the laser reflection signal. The laser reflection signal value corresponds to the distance between any point on the blade and the laser displacement sensor, thereby determining whether the blade rotation angle range meets the factory requirements.

[0036] The camera will record the blade inspection process during the inspection. When the inspection is completed, the camera will immediately end the video recording, thereby reducing the video memory and facilitating long-term video storage. At the same time, the video is named and saved according to the barcode information of the tested center console. Each center console barcode is unique, so it is convenient to find the inspection video of the corresponding center console according to the center console barcode in the future, thereby facilitating quality traceability.
