Description
Technical Field
[0001] This utility model relates to the field of automotive rearview mirror technology, and in particular to a testing device for automotive rearview mirror folding motors. Background Technology
[0002] With the development of the automotive rearview mirror industry, automotive rearview mirror modules are becoming increasingly integrated. Rearview mirror folding has now become the most basic function. The smooth operation of the folding motor is an important factor in ensuring the overall quality of the rearview mirror folding. Therefore, excessive decibels, noises, and wavy sounds that indicate a smooth operation need to be checked before shipment to prevent them from reaching customers and thus improve the customer's user experience.
[0003] In related technologies, abnormal sounds such as excessive decibels (>60 decibels), noises, and wave sounds generated when the folding motor is in operation need to be manually checked. However, manual checking depends entirely on personal subjective judgment, which is not only time-consuming and laborious, but also cannot guarantee the consistency of judgment, and is prone to misjudgment.

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0041] See Figure 1 , Figure 1A schematic diagram of the structure of a detection device for a folding motor of a car rearview mirror is shown in one embodiment of this application. The detection device for a folding motor of a car rearview mirror provided in one embodiment of this application includes a soundproof box 1, a bottom bracket 2, a lifting door 3, a connector 4, a grating 5, an integrated industrial control display screen 8, a controller 9, a moving wheel 10, an internal detection mechanism, a visual detection mechanism, a noise detection mechanism 18, and an environmental adjustment mechanism.
[0042] In some embodiments, the soundproof enclosure 1 is a single-sided open enclosure structure designed to isolate external noise and ensure the accuracy of the testing environment.
[0043] Furthermore, a lifting door 3 is provided on the opening side. The two sides of the lifting door 3 are connected to the drive cylinder through the connecting parts 4, and the drive cylinder drives it to rise and fall.
[0044] Furthermore, to ensure the accurate closing of the lifting door 3, a light grating 5 is installed on its descent path. The light grating 5 is used to detect the descent status of the lifting door 3. When the lifting door 3 descends to the preset position, the light grating 5 sends a signal to ensure the airtightness of the soundproof enclosure 1.
[0045] In some embodiments, an internal testing mechanism is disposed inside the soundproof enclosure 1 for fixing and testing the folding motor. Specifically, the internal testing mechanism includes a fixture fixing block 11, a folding motor fixing fixture 12, and a folding motor bottom support 13. The folding motor is fixed by the folding motor fixing fixture 12 and the folding motor bottom support 13, ensuring the stability of the motor during testing. The bottom of the fixture fixing block 11 also cooperates with the fixture fixing block slide rail 14, allowing the folding motor fixing fixture 12 to slide along the length of the slide rail, thereby adjusting the position of the motor to meet the testing requirements of folding motors of different models or sizes.
[0046] Furthermore, the folding motor fixing fixture 12 includes a fixing component mounting plate 121 and a fixing component 122. The fixing component 122 is mounted on the fixing component mounting plate 121, and the fixing component mounting plate 121 is fixedly connected to the fixture fixing block 11.
[0047] See Figure 3 The diagram shows a schematic representation of the fixing component 122 of this invention. Specifically, the fixing component 122 includes a fixing motor assembly block 1221, on which a fixing motor 1222 is mounted. A gripper 1223 is mounted at the output end of the fixing motor 1222. When it is necessary to fix the folding motor, the fixing motor 1222 drives the gripper 1223 to advance along the direction of the folding motor, thereby fixing the motor. After the detection is completed, the gripper 1223 retracts, releasing the motor. The entire process is quick and convenient.
[0048] See Figure 2 As shown, Figure 2 A schematic diagram of the internal structure of a folding motor for a car rearview mirror is shown in one embodiment of this application.
[0049] In some embodiments, a visual inspection mechanism is also disposed inside the soundproof enclosure 1, used to capture an image pattern of the folding motor and compare it with a standard template to determine whether the image is qualified. Specifically, the visual inspection mechanism includes a first support 15, a second support 19, an IV3 camera 17, a visual camera 21, and a camera imaging display screen 20;
[0050] The first bracket 15 is provided with a first bracket extension 16. The IV3 camera 17 is mounted on the first bracket extension 16 and faces the folding motor to capture the image pattern of the motor. After the IV3 camera 17 is decoded by the decoder, the image pattern is displayed on the camera image display screen 20. The camera image display screen 20 is mounted on the second bracket 19, and the vision camera 21 faces the camera image display screen 20 to further observe and analyze the image pattern.
[0051] In some embodiments, the noise detection mechanism 18 is mounted at the end of the first bracket extension 16 and located directly above the folding motor, and includes at least one stereo microphone. The stereo microphone is used to detect the noise generated by the folding motor and can filter out noise to ensure the accuracy of the detection results.
[0052] In some embodiments, an environmental control mechanism is mounted on the soundproof enclosure 1 to regulate the working environment. Specifically, the environmental control mechanism includes a fan 6 mounted on top of the lifting door 3, a lighting lamp 7 mounted below the fan 6, and an integrated industrial control display screen 8 mounted below the lighting lamp 7.
[0053] The fan 6 has its air outlet facing the worker's standing position, and is used to adjust the airflow to the worker to provide a comfortable working environment; the lighting 7 provides stable lighting conditions to ensure the accuracy of visual inspection; the industrial control integrated display screen 8 is used to display the status of the folding motor inside the soundproof enclosure 1 and the noise decibel value detected by the noise detection mechanism 18, providing the operator with intuitive detection feedback.
[0054] In some embodiments, a controller 9 is provided on the bottom support 2. The controller 9 controls the operation of the drive cylinder, the internal detection mechanism, the visual inspection mechanism, the noise detection mechanism 18 and the environmental adjustment mechanism through a preset program, thereby realizing the automation and intelligence of the detection process.
[0055] In some embodiments, the bottom support 2 rests against the ground via the casters 10, making the entire testing device easy to move and position, facilitating flexible transfer between different production or testing areas.
[0056] This invention provides a testing device for folding motors of automotive rearview mirrors. It isolates external noise through a soundproof enclosure 1, stabilizes and tests the folding motor within an internal testing mechanism, and comprehensively evaluates the condition and noise of the folding motor using a visual testing mechanism and a noise testing mechanism 18. An environmental adjustment mechanism optimizes the working environment and improves operator comfort. Furthermore, it provides convenient mobility through a bottom bracket 2 and casters 10. Therefore, this invention offers technical advantages such as comprehensive, efficient, accurate, intelligent, and convenient mobility, helping to improve the testing efficiency and consistency of automotive rearview mirror folding motors, reduce production costs, and enhance product quality.
[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
