Description

Technical Field

[0001] This utility model belongs to the technical field of sunshade quality inspection equipment, and relates to a sunshade light detection device. Background Technology

[0002] In the automotive interior manufacturing industry, the sun visor is a key component that ensures driving visibility and passenger comfort. Its integrated lighting function must strictly comply with industry safety standards and user needs. After the sun visor frame and cover are assembled, the on / off logic of the internal lights must be precisely tested. Specifically, when the cover is opened to a preset angle, the bulb should be powered on immediately to provide clear illumination for the user; when the cover is rotated in the opposite direction to close, the bulb should be powered off simultaneously when the rotation angle reaches a specific threshold to avoid energy waste and potential safety hazards. This testing process directly determines the functional integrity and reliability of the sun visor and is a core quality control point before the product leaves the factory.

[0003] However, the current industry standard for this testing requirement generally relies on manual operation: workers manually open and close the sun visor cover, relying on visual observation of light changes and subjective judgment of whether the on / off timing meets the standards. This not only results in low testing efficiency and high labor costs, but also leads to inconsistent test results and difficulty in guaranteeing accuracy due to individual operational differences (such as deviations in opening / closing speed and angle judgment) and visual errors, failing to meet the quality control requirements of large-scale production. Furthermore, there is a lack of standardized equipment on the market that can simulate actual usage scenarios and automatically complete the simultaneous testing of sun visor opening / closing and light on / off. This makes it impossible to achieve quantitative recording and data traceability of the testing process, and it is also difficult to adapt to the testing needs of different specifications of sun visors, severely restricting the standardization and efficiency of the sun visor production process. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a sunshade light detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sun visor light detection device includes a base, on which a sun visor frame fixing mechanism and a sun visor cover opening and closing mechanism are provided. The sun visor cover opening and closing mechanism includes a servo motor disposed on the side of the sun visor frame fixing mechanism. The servo motor is connected to a swing arm through a reducer. A cover suction cup assembly is disposed at the end of the swing arm away from the reducer. A light detection mechanism is also provided on the upper side of the sun visor frame fixing mechanism. The device also includes an angle detection module for detecting the opening and closing angle between the cover and the frame when the cover is opened and closed, and a microcontroller. The servo motor, the light detection mechanism, and the angle detection module are all connected to the microcontroller.

[0007] The microcontroller can record the opening and closing angle of the mirror cover detected by the angle detection module when the light detection mechanism detects a change in the light on the sun visor.

[0008] In the aforementioned sunshade light detection device, the angle detection module includes a motor encoder mounted on the servo motor.

[0009] In the aforementioned sunshade light detection device, the light detection mechanism includes a first mounting rod vertically fixed on a base, an adjustable seat fixedly connected to the top of the first mounting rod, a second mounting rod horizontally arranged on the adjustable seat, and a light sensor with the light detection direction pointing downwards connected to the end of the second mounting rod via a clamping plate structure.

[0010] In the aforementioned sunshade light detection device, the adjustable seat includes two mounting rod fixing plates connected by a first fixing bolt, and the second mounting rod is disposed between the two mounting rod fixing plates.

[0011] In the aforementioned sunshade light detection device, the clamping structure includes two clamping plates symmetrically arranged at the ends of the second mounting rod, the light sensor is fixed between the two clamping plates, and a second fixing bolt is provided between the two clamping plates.

[0012] In the aforementioned sun visor light detection device, the mirror cover suction cup assembly includes a suction cup mounting rod horizontally fixed to the end of the swing arm away from the reducer. The end of the suction cup mounting rod is fixedly connected to a suction cup mounting seat, and the suction cup mounting seat is fixedly connected to a mirror cover suction cup that is connected to a negative pressure pump via a flexible hose.

[0013] In the aforementioned sun visor light detection device, the sun visor frame fixing mechanism includes a fixing base, the top of which is recessed inward to provide a sun visor mounting groove, and a frame positioning seat protruding from the sun visor mounting groove. A frame slot is formed between the outer edge of the frame positioning seat and the sun visor mounting groove.

[0014] In the aforementioned sun visor light detection device, the depth of the sun visor mounting groove is less than the height of the sun visor frame.

[0015] In the aforementioned sunshade light detection device, a first opening for taking out and putting in materials is provided on the front side of the sunshade mounting groove.

[0016] In the aforementioned sun visor light detection device, a second opening for rotating the mirror cover is provided on the rear side of the sun visor mounting groove.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] 1. By coordinating the sun visor frame fixing mechanism and the visor cover opening and closing mechanism, the automatic opening and closing operation of the visor cover is realized; the light detection mechanism and the angle detection module work together, and under the control of the microcontroller, the opening and closing angle of the visor cover when the light changes. This design solves the problems of subjectivity and inaccuracy of manual detection, realizes the standardized and automated detection of the on / off state of the sun visor light, and improves detection efficiency and accuracy.

[0019] 2. The angle detection module uses a motor encoder mounted on the servo motor to directly acquire the motor rotation angle, thereby accurately calculating the opening and closing angle of the mirror cover. This structure solves the problems of complexity and insufficient accuracy in traditional angle detection methods, ensuring the real-time performance and accuracy of mirror cover angle detection, and providing reliable data support for determining the on / off standard of the lights.

[0020] 3. The light detection mechanism, through the cooperation of the first mounting rod, the adjustable base, and the second mounting rod, enables multi-dimensional position adjustment of the light sensor, ensuring its detection direction is precisely aligned with the light area of ​​the sun visor.

[0025] like Figures 1-3As shown, a sun visor light detection device includes a base 1, on which a sun visor frame fixing mechanism 2 and a sun visor cover opening and closing mechanism 3 are mounted. The sun visor cover opening and closing mechanism 3 includes a servo motor 4 disposed on the side of the sun visor frame fixing mechanism 2. The servo motor 4 is connected to a swing arm 5 via a reducer. A cover suction cup assembly 6 is disposed at the end of the swing arm 5 away from the reducer. A light detection mechanism 7 is also disposed on the upper side of the sun visor frame fixing mechanism 2. The device also includes an angle detection module 8 for detecting the opening and closing angle between the cover and the frame when the cover is opened and closed, and a microcontroller 26. The servo motor 4, the light detection mechanism 7, and the angle detection module 8 are all connected to the microcontroller 26. The microcontroller 26 can record the opening and closing angle of the cover detected by the angle detection module 8 when the light detection mechanism 7 detects a change in the sun visor light.

[0026] In this invention, the automatic opening and closing operation of the mirror cover is achieved through the cooperation of the sun visor frame fixing mechanism and the mirror cover opening and closing mechanism; the light detection mechanism and the angle detection module work together, and under the control of the microcontroller, the opening and closing angle of the mirror cover when the light changes. This design solves the problems of subjectivity and inaccuracy of manual detection, realizes the standardized and automated detection of the on / off state of the sun visor light, and improves detection efficiency and accuracy.

[0027] Specifically, the angle detection module 8 includes a motor encoder 9 mounted on the servo motor 4. The angle detection module uses a motor encoder mounted on the servo motor to directly acquire the motor rotation angle, and then accurately calculate the opening and closing angle of the mirror cover. This structure solves the problems of complexity and insufficient accuracy in traditional angle detection methods, ensuring the real-time performance and accuracy of mirror cover angle detection, and providing reliable data support for determining the on / off standard of the lights.

[0028] Specifically, the light detection mechanism 7 includes a first mounting rod 10 vertically fixed to the base 1. An adjustable seat 11 is fixedly connected to the top of the first mounting rod 10, and a second mounting rod 12 is horizontally mounted on the adjustable seat 11. The end of the second mounting rod 12 is connected to a light sensor 13 with a downward light detection direction via a clamping structure. Through the cooperation of the first mounting rod, the adjustable seat, and the second mounting rod, the light detection mechanism achieves multi-dimensional position adjustment of the light sensor, ensuring that its detection direction is accurately aligned with the light area of ​​the sun visor. This design solves the problem of difficulty in adapting the sensor position when detecting light on sun visors of different specifications, ensuring that the light sensor can stably and accurately detect changes in light, and improving the versatility of the device.

[0029] Those skilled in the art will understand that the optical sensor can be a photoresistor or a photodiode.

[0030] Specifically, the adjustable base 11 includes two mounting rod fixing plates 14 connected by first fixing bolts (not shown in the figure), and the second mounting rod 12 is disposed between the two mounting rod fixing plates 14. The adjustable base uses two mounting rod fixing plates connected by first fixing bolts, allowing the installation height and angle of the second mounting rod to be flexibly adjusted and securely fixed. This structure solves the problem of inflexible adjustment in traditional fixed installation methods, ensuring that the optical sensor can be accurately positioned according to different detection requirements, and enhancing the adjustment convenience and stability of the device.

[0031] Specifically, the clamping structure includes two clamping plates 15 symmetrically arranged at the ends of the second mounting rod 12. The light sensor 13 is fixed between the two clamping plates 15, and a second fixing bolt 16 is provided between the two clamping plates 15. The clamping structure, through the cooperation of the two clamping plates and the second fixing bolt, achieves stable installation and fine-tuning of the light sensor's angle. This design solves the problem of unstable installation or difficulty in precise angle adjustment of the light sensor, ensuring the sensor remains stable during detection and improving the accuracy and reliability of light detection.

[0032] Specifically, the lens cover suction cup assembly 6 includes a suction cup mounting rod 17 horizontally fixed to the end of the swing arm 5 away from the reducer. A suction cup mounting seat 18 is fixedly connected to the end of the suction cup mounting rod 17, and a lens cover suction cup 19 connected to the suction cup mounting seat 18 via a flexible hose and a negative pressure pump (not shown in the figure) is fixedly connected to the suction cup mounting seat 18. Through the cooperation of the suction cup mounting rod, the suction cup mounting seat, and the lens cover suction cup, the lens cover assembly uses negative pressure to firmly adhere the lens cover, achieving smooth opening and closing of the lens cover under the action of the swing arm. This structure solves the problem of easy damage to the lens cover caused by traditional mechanical clamping methods, while ensuring uniform force and smooth movement of the lens cover during opening and closing, thus guaranteeing the stability of the testing process.

[0033] Specifically, the sun visor frame fixing mechanism 2 includes a fixing base 20. The top of the fixing base 20 is recessed inwards, providing a sun visor mounting groove 21. A frame positioning seat 22 protrudes from the sun visor mounting groove 21. A frame locking groove 23 is formed between the outer edge of the frame positioning seat 22 and the sun visor mounting groove 21. The sun visor frame fixing mechanism achieves rapid positioning and stable installation of the sun visor frame through the sun visor mounting groove on the fixing base and the frame positioning seat forming the frame locking groove. This design solves the problems of cumbersome operation and inaccurate positioning in traditional fixing methods, ensuring that the sun visor does not shift during testing and providing a fundamental guarantee for the accuracy of the test.

[0034] Specifically, the depth of the sun visor mounting groove 21 is less than the height of the sun visor frame. This design ensures the top of the frame is exposed within the groove, preventing interference with the opening and closing of the lens cover. This solves the problem of obstructed rotation of the lens cover after frame installation, ensuring smooth opening and closing of the lens cover and guaranteeing the smooth progress of the testing process.

[0035] Specifically, the sunshade mounting slot 21 has a first opening 24 on its front side for loading and unloading materials. This first opening facilitates quick loading and unloading of the sunshade, simplifying the loading and unloading operations. This design solves the problem of inconvenient material loading and unloading in traditional enclosed installation structures, shortens auxiliary inspection time, and improves inspection efficiency.

[0036] Specifically, a second opening 25 for rotating the lens cover is provided on the rear side of the sun visor mounting groove 21. This second opening provides ample space for the lens cover to rotate, preventing collisions between the lens cover and the mounting groove during rotation. This design solves the problem of limited rotation range of the lens cover, ensuring that the lens cover can fully simulate the actual opening and closing process, thus guaranteeing the comprehensiveness and authenticity of the testing.
