Description

Technical Field

[0001] This utility model relates to the field of skylight sunshade detection technology, and in particular to a laser rangefinder. Background Technology

[0002] The sunroof sunshade sag test is a key quality control item for automotive sunroof sunshades. Its core function is to measure the amount of sagging deformation that occurs when the sunshade is in its unfolded state, due to factors such as material properties, installation precision, and structural design. During testing, it is typically necessary to simulate actual usage scenarios (such as fully unfolded and subjected to a certain ambient temperature) and use professional measuring tools (such as high-precision laser rangefinders and displacement sensors) to quantitatively collect data on the vertical distance deviation between key positions such as the center and edges of the sunshade and a standard reference plane. The test results are directly related to the sunshade's appearance flatness, operational stability, and lifespan. Excessive sag not only affects the visual aesthetics of the vehicle interior but may also cause the sunshade to jam, rub against the sunroof frame with abnormal noise, and even exacerbate deformation due to vibration during vehicle operation, reducing its sunshade and heat insulation effects. Therefore, it is one of the important indicators for factory quality inspection and after-sales quality assessment of sunroof sunshades.

[0003] Therefore, we propose a laser rangefinder to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a laser rangefinder that addresses the significant shortcomings of existing technologies for testing sunroof sunshades: on the one hand, existing testing procedures are cumbersome and time-consuming, resulting in low testing efficiency and making it difficult to meet the needs of mass production or rapid quality inspection; on the other hand, conventional testing methods are limited by technical principles and cannot perform high-precision quantitative measurement of key indicators such as the sag of sunroof sunshades, which easily leads to data deviations and makes it difficult to accurately assess whether the product quality meets the standards, thus creating potential problems for subsequent use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A laser rangefinder includes a movable frame, on the top of which a limiting mechanism for fixing a skylight sunshade is fixedly installed, and on the top of which a plurality of laser rangefinders for detecting the droop of the skylight sunshade are also fixedly installed.

[0006] As a preferred embodiment of the above technical solution, the limiting mechanism includes several first support seats. There are four first support seats, and the four first support seats are symmetrically distributed in pairs on the top of the movable frame. Each first support seat is fixedly installed with a handheld self-locking pressing clamp on its top. Each handheld self-locking pressing clamp has a limiting opening on its surface for limiting the protrusions on the surface of the sunroof curtain.

[0007] As a preferred embodiment of the above technical solution, the limiting mechanism further includes two second support seats, which are symmetrically fixedly installed on the top of the movable frame on both sides, and each second support seat is located between two adjacent first support seats. Each second support seat is rotatably connected to a lower pressure plate by bolts.

[0008] As a preferred embodiment of the above technical solution, brackets are symmetrically fixedly installed on both sides of the top of the mobile frame, and a skylight sunshade is placed on the upper surface of the two brackets, with the lower surfaces of the two lower pressure plates pressing against the upper surface of the skylight sunshade.

[0009] As a preferred embodiment of the above technical solution, the limiting mechanism further includes several third support seats, the surface of the sunroof shading curtain is provided with openings, each of the third support seats is provided with a positioning pin, and each positioning pin passes through the corresponding opening.

[0010] As a preferred embodiment of the above technical solution, the laser ranging mechanism includes several high-precision laser measuring instruments, each of which is fixedly installed on the top of the mobile frame in an orderly manner, and each of which is located at the bottom of the skylight sunshade. A display screen is fixedly installed on the surface of each of the high-precision laser measuring instruments.

[0011] This utility model has at least the following beneficial effects: A multi-dimensional fixing system is constructed through a limiting mechanism. The self-locking clamp of the first support seat precisely matches the sunshade protrusion through the limiting port. The lower pressure plate of the second support seat abuts against the surface to form pressure constraint. The positioning pin of the third support seat achieves rigid limiting through the pin hole. The three work together to eliminate displacement interference in the measurement of the sunshade. With the high-precision laser measuring instruments arranged in an orderly manner at the bottom, the vertical incidence of the laser beam reduces propagation deviation. Combined with the high-sensitivity signal capture capability, the sag data at each point can be accurately obtained.

[0012] This utility model also has the following beneficial effects: High-precision laser measuring instruments are arranged in an orderly manner according to the area of ​​the sunshade to be tested, and can simultaneously cover multiple key points such as the edges and the middle, realizing all-round detection of the overall drooping state of the sunshade. Compared with single-point measurement methods, it can more comprehensively reflect the drooping distribution characteristics of the sunshade, providing more complete data support for quality assessment.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Reference Figure 1-5 A laser rangefinder includes a movable frame 1, a limiting mechanism 2 for fixing a skylight sunshade 10 is fixedly installed on the top of the movable frame 1, and several laser rangefinders 3 for detecting the droop of the skylight sunshade 10 are also fixedly installed on the top of the movable frame 1.

[0018] Furthermore, the limiting mechanism 2 includes several first support seats 4. There are four first support seats 4, and the four first support seats 4 are symmetrically distributed in pairs on the top of the movable frame 1. Each first support seat 4 is fixedly installed with a handheld self-locking pressing clamp 5. Each handheld self-locking pressing clamp 5 has a limiting opening 6 on its surface for limiting the protrusions on the surface of the sunshade 10. Specifically, the shape and size of the limiting opening 6 are precisely designed to perfectly fit the protrusions on the surface of the sunshade 10. When the protrusions are embedded in the limiting opening 6, it can not only limit the movement of the sunshade in the horizontal direction, but also play a certain role in constraining the vertical position of the sunshade, so as to prevent the sunshade from shifting during the fixing process and ensure the accuracy of the initial fixing position of the sunshade.

[0019] Furthermore, the limiting mechanism 2 also includes two second support seats 7, which are symmetrically fixedly installed on the top of the movable frame 1 on both sides. Each second support seat 7 is located between two adjacent first support seats 4. Each second support seat 7 is rotatably connected to a lower pressure plate 8 by bolts. Specifically, the bolt connection method not only ensures the connection strength between the lower pressure plate 8 and the second support seat 7, but also allows the lower pressure plate 8 to rotate flexibly around the bolts. The operator can adjust the rotation angle of the lower pressure plate 8 according to the installation of the sunshade curtain, so that the lower pressure plate 8 can contact the surface of the sunshade curtain at a suitable angle, so as to achieve a better pressing and fixing effect later.

[0020] Furthermore, brackets 9 are symmetrically fixed on both sides of the top of the movable frame 1. A skylight sunshade 10 is placed on the upper surface of the two brackets 9. The lower surfaces of the two lower pressure plates 8 are pressed against the upper surface of the skylight sunshade 10. Specifically, after the lower pressure plate 8 is adjusted to a suitable angle, the operator presses down on the lower pressure plate 8 so that the lower surface of the lower pressure plate 8 is in close contact with the upper surface of the sunshade and generates a certain pressure. Through the pressure, the vertical displacement of the sunshade is further restricted, preventing the sunshade from warping or sliding due to its own weight or slight external interference during the measurement process. It forms a coordinated fixing effect with the clamp on the first support 4.

[0021] Furthermore, the limiting mechanism 2 also includes several third support seats 11. The surface of the sunshade curtain 10 is provided with openings 12. Each third support seat 11 is provided with a positioning pin 13. Each positioning pin 13 passes through the corresponding opening 12. Specifically, after the positioning pin 13 is inserted from the surface of the third support seat 11 and passes through the opening 12 of the sunshade curtain, the positioning pin 13 can form a rigid constraint on the sunshade curtain from the position of the opening 12, limiting the horizontal and vertical displacement of the sunshade curtain. Together with the handheld self-locking pressure clamp 5 and the pressure plate 8, it forms a multi-directional and three-dimensional fixing system, which maximizes the positional stability of the sunshade curtain during measurement.

[0022] Furthermore, the laser ranging mechanism 3 includes several high-precision laser measuring instruments 14. Each high-precision laser measuring instrument 14 is fixedly installed on the top of the mobile frame 1 in an orderly manner, and each high-precision laser measuring instrument 14 is located at the bottom of the skylight sunshade 10. Each high-precision laser measuring instrument 14 has a display screen 15 fixedly installed on its surface. Specifically, the display screen 15 adopts a clear and easy-to-read display design, which can intuitively present the distance data, deviation value and other information obtained by the instrument in real time, making it convenient for operators to observe and record the measurement results at any time without the need to connect other display devices, thus simplifying the operation process.

[0023] In summary: the laser rangefinder provides stable overall support through the moving frame 1, and achieves multi-dimensional precise fixation of the sunshade 10 through the limiting mechanism 2. The handheld self-locking pressure clamp 5 engages with the sunshade protrusion through the limiting port 6, the pressure plate 8 presses against the surface of the sunshade, and the positioning pin 13 penetrates through the opening 12 of the sunshade. The three work together to effectively limit the displacement of the sunshade in all directions and ensure the stability of the sunshade position during the measurement process. The laser rangefinder 3 uses a high-precision laser measuring instrument 14, which is arranged in an orderly manner at the bottom of the sunshade and emits lasers. The distance is calculated by detecting the laser reflection signal, and the data is displayed in real time on the display screen 15 to accurately obtain the sag of the sunshade at each point. The overall equipment has a reasonable structural design, with clear division of labor and efficient collaboration among its various mechanisms. It can quickly and accurately complete the detection of the sag of the skylight sunshade 10, providing reliable data support for the quality inspection, installation and commissioning of the skylight sunshade 10. It is suitable for various scenarios that require detection of the sag status of the skylight sunshade 10, and has strong practicality and ease of operation.
