[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Example:

[0018] like Figure 1 As shown, this utility model provides an exterior mirror torsion torque detection device.

[0019] The device includes a pneumatic mechanism 1, a pressure plate 2, a fixing frame 3, a fixing rod 4, and a detection mechanism. The pneumatic mechanism 1 is mounted on the fixing frame 3. The pressure plate 2 is connected to the output end of the pneumatic mechanism 1. A bracket 5 is provided on one side of the fixing frame 3. The fixing rod 4 is vertically mounted on the surface of the bracket 5. The fixing rod 4 is configured in two sets, spaced apart, forming a clamping space between the two sets. One end of the exterior mirror toggle 6 is placed on the surface of the fixing frame 3, and the other end is located in the clamping space. The two sets of fixing rods 4 are used to limit the two side walls of the other end of the exterior mirror toggle 6. The detection mechanism is mounted on the surface of the pressure plate 2 and is used to detect the torque of the exterior mirror toggle 6.

[0020] The pneumatic mechanism 1 of this application provides power for the test, the pressure plate 2 is used to transmit power to the exterior mirror support 6, the fixing frame 3 provides a supporting foundation for the entire device, the fixing rod 4 is used to stabilize and fix the exterior mirror support 6, and the test mechanism realizes the torque test function. All components work together to ensure that the device can successfully complete the torque test task of the exterior mirror support 6.

[0021] A bracket 5 is provided on one side of the fixed frame 3, and two sets of vertically arranged and spaced fixed rods 4 form a clamping space. One end of the external mirror rotator 6 is placed on the surface of the fixed frame 3, and the other end is located in the clamping space. The two sets of fixed rods 4 limit the two side walls of the other end of the external mirror rotator 6, which can effectively prevent the external mirror rotator 6 from shaking or shifting during the test, ensuring the stability of the external mirror rotator 6 during the test, thereby improving the accuracy of torque detection.

[0022] The detection mechanism is set on the surface of the pressure plate 2, so that when the pneumatic mechanism 1 drives the pressure plate 2 to apply force to the external mirror rotator 6, the detection mechanism can directly detect the torque change of the external mirror rotator 6 during the force process, ensuring the real-time performance and accuracy of the detection data.

[0023] Optionally, the detection mechanism includes a torque sensor 7 and a data processing module. The torque sensor 7 is disposed on the surface of the pressure plate 2, and the detection end of the torque sensor 7 is in contact with the detection part of the exterior mirror mount 6. The data processing module is electrically connected to the torque sensor 7 and is used to receive and process the torque data detected by the torque sensor 7.

[0024] The testing mechanism includes a torque sensor 7 and a data processing module. The torque sensor 7 is set on the surface of the pressure plate 2 and its detection end is in contact with the detection part of the exterior mirror support 6. It can directly and accurately measure the torque of the exterior mirror support 6 when it is under force. The data processing module is electrically connected to the torque sensor 7 and receives and processes the detected torque data, which further improves the accuracy and reliability of torque detection and provides reliable data support for subsequent quality assessment and process improvement.

[0025] The application of the data processing module enables intelligent processing of torque detection data. It can not only display the detection data in real time, but also perform operations such as storage, analysis and statistics. By analyzing a large amount of detection data, abnormalities in the torque of the external mirror can be detected in a timely manner, providing a scientific basis for quality control in the production process and helping to improve product quality and production efficiency.

[0026] Common torque sensors 7 include strain gauge type and magnetoelectric type. In this application, a strain gauge type torque sensor 7 is used as an example. It works based on the strain effect. When the sensor is subjected to torque, its internal elastic element will undergo slight deformation, and the resistance value of the strain gauge attached to the elastic element will change. The torque sensor 7 is installed on the surface of the pressure plate 2 and fixed with bolts or other fasteners to ensure that the sensor is firmly connected to the pressure plate 2 and will not loosen during the detection process. At the same time, it is necessary to ensure that the detection end of the torque sensor 7 can accurately contact the detection part of the external mirror jack 6. For example, the external mirror jack 6 has a specific detection shaft. The detection end of the torque sensor 7 is designed to match the shape of the detection shaft, such as a sleeve structure with an inner hole. During detection, the detection shaft is inserted into the inner hole of the detection end of the torque sensor 7 so that the two fit tightly. In this way, when the external mirror jack 6 is subjected to force and rotates, the torque can be accurately transmitted to the torque sensor 7.

[0027] When the pneumatic mechanism 1 drives the pressure plate 2 to apply force to the outer sight mirror 6, the outer sight mirror 6 is subjected to torque and begins to rotate. Since the torque sensor 7 is in close contact with the detection part of the outer sight mirror 6, the torque of the outer sight mirror 6 will be transmitted to the inside of the torque sensor 7 through the detection end.

[0028] When torque causes the elastic element to deform, the resistance of the strain gauge changes. According to the Wheatstone bridge principle, four strain gauges are combined to form a bridge circuit. When the resistance changes, the output voltage of the bridge also changes. This output voltage is proportional to the torque applied to the sensor. By measuring the magnitude of the output voltage, the value of the torque can be obtained. For example, when the external mirror rotor 6 is subjected to a small torque, the strain gauge deformation is small, and the bridge output voltage is low; when the torque increases, the strain gauge deformation increases, and the bridge output voltage also increases.

[0029] The data processing module is electrically connected to the torque sensor 7 via a signal line. The signal line transmits the electrical signal, such as a voltage signal, output by the torque sensor 7 to the data processing module. For example, using a shielded signal line can effectively reduce the impact of external electromagnetic interference on signal transmission and ensure that the transmitted signal is accurate.

[0030] The data processing module has a dedicated signal acquisition circuit that can sample and quantize the input electrical signal. Sampling discretizes the continuous analog signal in time, while quantization converts the amplitude value of the sampled signal into a digital value. For example, the sampling frequency is set to 1000 times per second, meaning that the output signal of the torque sensor 7 is sampled 1000 times per second. Then, the voltage value of each sampling point is converted into a corresponding digital code for subsequent processing.

[0031] During actual testing, various noises, such as power supply noise and electromagnetic interference, may interfere with the collected torque data, causing fluctuations. The data processing module will filter the collected data. Commonly used filtering algorithms include mean filtering and median filtering. Taking mean filtering as an example, it averages multiple consecutive sampled data and uses the average value to replace the current sampled value, thereby reducing the influence of random noise. For example, averaging the data from 5 consecutive sampled points yields a smoother torque value.

[0032] The data processing module can analyze and calculate the filtered torque data according to a preset algorithm. For example, it can calculate the average, maximum, and minimum values ​​of the torque to evaluate the overall performance of the torque of the exterior mirror rotor 6. It can also analyze the trend of torque change based on the torque change curve over time to determine whether there are any abnormalities in the rotation of the exterior mirror rotor 6, such as a sudden increase or decrease in torque.

[0033] The processed torque data can be displayed in real time on the screen for operators to observe. At the same time, the data processing module can also store the data in the internal memory or external storage devices such as USB flash drives or hard drives for subsequent traceability and analysis. For example, the torque data of each external mirror torsion beam test can be classified and stored according to information such as date and batch, which facilitates quality management personnel to track and evaluate product quality over a long period of time.

[0034] Suppose that torque detection is required for the exterior mirror mount 6 on an automotive parts production line. First, the exterior mirror mount 6 is placed in a fixed position on the detection device, so that the detection end of the torque sensor 7 is tightly fitted with the detection shaft of the exterior mirror mount 6. Then, the pneumatic mechanism 1 is activated, and the cylinder drives the pressure plate 2 to apply force to the exterior mirror mount 6. The exterior mirror mount 6 begins to rotate, and the torque sensor 7 detects the torque in real time and transmits the electrical signal to the data processing module through the signal line.

[0035] After receiving the signal, the data processing module first performs filtering to remove noise interference. Then, it calculates the average, maximum, and minimum torque values ​​and displays the results on the screen. For example, it displays the current average torque of the exterior mirror tow rest 6 as 5 N·m, the maximum as 5.2 N·m, and the minimum as 4.8 N·m. Simultaneously, the data processing module stores the detected data in a database for subsequent quality traceability and statistical analysis. If the detected torque value exceeds the preset acceptable range, the data processing module will issue an alarm signal, prompting the operator that the torque of the exterior mirror tow rest 6 is unacceptable and requires further processing.

[0036] Optionally, the pneumatic mechanism 1 includes a cylinder and a pneumatic control valve. The cylinder is fixedly mounted on the fixed frame 3, and the pneumatic control valve is connected to the cylinder to control the extension and retraction of the cylinder. The piston rod of the cylinder is connected to the pressure plate 2 as the output end of the pneumatic mechanism 1.

[0037] The pneumatic mechanism 1 includes a cylinder and a pneumatic control valve. The cylinder is fixedly mounted on the fixed frame 3, and the pneumatic control valve is connected to the cylinder to control the extension and retraction of the cylinder. The pneumatic control valve can precisely control the intake and exhaust volume of the cylinder, thereby achieving precise adjustment of the extension and retraction speed and force of the cylinder piston rod. This ensures that the pneumatic mechanism 1 can stably and reliably provide power to the pressure plate 2, guaranteeing the stability of the force applied to the external sight mirror rotor 6 during the detection process, and thus improving the accuracy of torque detection.

[0038] Optionally, the surface of the fixing rod 4 is provided with an elastic buffer layer, which wraps around the surface of the fixing rod 4 that contacts the exterior mirror support 6, and is used to buffer the collision force between the exterior mirror support 6 and the fixing rod 4 during the limiting process.

[0039] An elastic buffer layer is provided on the surface of the fixing rod 4 and wraps around the surface that contacts the exterior mirror support 6. During the limiting process, it can effectively buffer the collision force between the exterior mirror support 6 and the fixing rod 4. When the exterior mirror support 6 is subjected to external force during the inspection process and causes slight shaking or contact with the fixing rod 4, the elastic buffer layer can absorb and disperse the collision energy, prevent the exterior mirror support 6 from being damaged by the collision, reduce the product defect rate, and improve production efficiency.

[0040] Optionally, the fixing rod 4 and the bracket 5 are integrally formed, or the fixing rod 4 is fixedly welded to the surface of the bracket 5.

[0041] This application establishes a compact and easy-to-operate torque detection device by setting up a pneumatic mechanism 1, a pressure plate 2, a fixing frame 3, a fixing rod 4, and a detection mechanism. The pneumatic mechanism 1 provides power, and the pressure plate 2 applies pressure to the exterior mirror mount 6. The fixing rod 4 limits the movement of the exterior mirror mount 6 to ensure stability during the detection process. The detection mechanism includes a torque sensor 7 and a data processing module. The torque sensor 7 can directly contact the detection part of the exterior mirror mount 6 to detect torque data in real time and accurately. The data processing module is responsible for receiving and processing this data to provide users with clear detection results, which helps to accurately evaluate the torque performance of the exterior mirror mount 6.
