Description

Technical Field

[0001] The utility model relates to the technical field of automobile door hinge torque detection, and more specifically, to an automobile door hinge torque detection device. Background Technique

[0002] An automobile door hinge is an important component connecting the automobile body and the door. Its main function is to support the door, enable the door to be firmly hung on the vehicle body, and realize the opening and closing movement of the door. An automobile door hinge torque detection device is a device used to detect the torque value of an automobile door hinge. By detecting the torque of the automobile door hinge, the comfort when the door is opened, as well as the performance and reliability of the hinge can be ensured, which is very important for the safety and long-term use of the automobile.

[0003] However, most of the current traditional detection methods use a lever structure for testing. This method has many significant defects and deficiencies. Firstly, it performs poorly in terms of operation test accuracy. Due to the limitations of its structure and working principle, it is difficult to achieve high-precision torque measurement, and the measurement results often have large errors, unable to meet the increasingly strict accuracy requirements for automobile door hinge torque detection. Secondly, the test speed and efficiency are relatively slow. The operation process of the lever structure is relatively cumbersome and takes a lot of time to complete a test. In the scenarios of large-scale production and quality inspection, this will seriously affect the production progress and detection efficiency. Moreover, the commonality of the fixture is extremely single. Automobile door hinges of different models and specifications often require specially designed and manufactured corresponding fixtures, which not only increases the detection cost but also makes the management and maintenance of the fixtures complicated. In particular, it should be pointed out that in the process of converting torque with this lever structure, torque loss will inevitably occur, which means that there is a deviation between the actually measured torque value and the torque actually borne by the hinge, thus affecting the accuracy and reliability of the detection results.

[0004] In view of this, we propose an automobile door hinge torque detection device. Content of the Utility Model
