Description

Technical Field

[0001] This invention relates to the field of cosmetic testing technology, and in particular to a cosmetic anti-wrinkle performance testing device that facilitates three-dimensional benchmarking. Background Technology

[0002] In the field of testing the anti-wrinkle performance of cosmetics, existing technologies mostly employ optical imaging equipment to acquire images of human facial skin in order to analyze the anti-wrinkle effects of cosmetics. For example, a testing system similar to the one shown in the image acquires a three-dimensional image of the face through an optical scanning device, and then uses computer software to process and analyze the image to quantify relevant wrinkle parameters. While these systems have achieved a certain degree of detection of the anti-wrinkle performance of cosmetics, they have shortcomings in terms of structural design and optical illumination. In existing testing, the subject places their head on a fixation device with a chin rest. The head position is fixed by adjusting the height of the chin rest, ensuring the face is within the effective range of the detection device. The device can perform multi-directional scanning of the face without requiring manual movement from the subject. The device adjusts through its own optical system to detect different areas of the face, and finally transmits the acquired images to a computer for analysis to evaluate the anti-wrinkle performance of cosmetics. Traditional cosmetic anti-wrinkle performance testing systems rely on a single point on the support plate to bear the pressure on the subject's chin. This localized pressure can easily exceed the human comfort threshold, leading to discomfort during prolonged testing and affecting the continuity and accuracy of the data. Furthermore, in the concave area where the chin connects to the cheek, traditional designs are prone to creating shadows due to head obstruction of light, obscuring details such as skin texture and chin contour. This results in a lack of clarity in the analysis of 3D images, ultimately leading to biased assessments of the cosmetic's anti-wrinkle performance.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0004] This invention provides a cosmetic anti-wrinkle performance testing device that facilitates three-dimensional benchmarking, thereby solving the problems of traditional cosmetic anti-wrinkle testing systems, such as single-point bearing on the chin causing discomfort to the experimenter and affecting data, shadows in the chin and cheek depression areas, unclear details leading to deviations in anti-wrinkle assessment.

[0005] This invention employs the following technical solution: a cosmetic anti-wrinkle performance testing device that facilitates three-dimensional benchmarking. It includes a placement platform; a control component disposed on the placement platform, used to perform three-dimensional scanning of the subject's face to provide data support for cosmetic anti-wrinkle performance analysis; a support component disposed on the control component, used to adapt to different facial contours, dispersing chin pressure and improving comfort; an adjustment component disposed on the support component, used to flexibly adjust the contact position according to the chin width of different subjects; a lighting component disposed on the adjustment component, used to illuminate the concave area where the chin and cheek connect; and a cleaning component disposed on the adjustment component, including components for cleaning the contact area with the subject.

[0006] Furthermore, the control component includes an arc-shaped support platform fixed to the placement platform. A semi-circular track is fixed on the support platform.

Two sets of symmetrically arranged arc-shaped parts are fixed on the contact portion. A sliding buckle plate is slidably disposed at the upper center of the contact portion. A through-type open slide groove for the sliding buckle plate to slide is opened on the contact portion. A limiting groove is connected to the open slide groove. A limiting block for use with the limiting groove is fixed on the bottom surface of the sliding buckle plate near one end.

[0010] Furthermore, the adjustment component includes movable arc blocks with sliding fasteners on two sets of arc-shaped parts. A flexible pad one is provided on the movable arc block, and a flexible pad two is provided on the sliding fastener plate. The flexible pad one and the flexible pad two are made of skin-friendly material and form a continuous support surface by overlapping and cooperating. The flexible pad one on the movable arc block partially extends into the flexible pad two from the side. An anti-slip convex pad is integrally provided with an upward-facing anti-slip convex pad at one end of the flexible pad two. The anti-slip convex pad increases the friction for hand operation. Opening slots are provided on both sides of the flexible pad two for placing the flexible pad one. An elastic support pad is hinged to one end of the movable arc block by a torsion spring. A contact member is fixed on the mounting base to push the elastic support pad to rotate along the hinge point with the movable arc block.

[0011] Furthermore, a concave frame is fixed to the bottom surface of the contact portion. A positive and negative threaded rod is connected to the inner bearing of the concave frame. One end of the positive and negative threaded rod passes through the concave frame and is fixed to a rotating wheel. Two sets of slides are threaded onto the positive and negative threaded rods. A support rod is vertically and movably installed on one side of the slide. One end of the support rod passes through the concave frame. A groove is opened on the bottom surface of the concave frame for the support rod to move. A support block is fixed to one end of the support rod. The support block is connected to the side of the movable arc block. A tension spring is sleeved on the support rod. One end of the tension spring is connected to the bottom surface of the support block, and the other end is connected to the upper surface of the slide, forming an elastic tension structure.

[0012] Furthermore, the light and shadow assembly includes a bracket fixed to the bottom surface of the movable arc block. One end of the bracket is hinged to a mounting shell via a torsion spring. A light strip is embedded in the mounting shell. A T-shaped groove is formed on the side of the mounting shell. A slider is slidably arranged in the T-shaped groove. A spring is fixed to the side of the slider. One end of the spring is connected to one end of the inner wall of the T-shaped groove. Switches are fixed at both ends of the inner wall of the T-shaped groove. A set of switches is located at the center of the spring.

[0013] Furthermore, a pull rope is connected to the slider via a hanging ring, and a connector that connects to the other end of the pull rope is fixed to the bottom surface of the elastic support.

[0014] Furthermore, the cleaning assembly includes a second concave frame fixed to one side of the concave frame. A second lead screw is connected to the second concave frame via a bearing. One end of the second lead screw passes through the second concave frame and is fixed to a second rotating wheel. A translation block is threaded onto the second lead screw. A vertical rod is vertically inserted through the translation block near one side. One end of the vertical rod is fixed to a mounting rod by fasteners. A wiping sponge is provided on the bottom surface of the mounting rod. The wiping sponge directly contacts the movable arc block and the surface of the elastic support pad. The mounting rod is located in an open sliding groove and its upper surface contacts the bottom surface of the sliding plate. A fourth spring is sleeved on the vertical rod. The two ends of the fourth spring are respectively connected to the upper surface of the translation block and the lower surface of the mounting rod. The fourth spring provides an upward elastic force to the mounting rod.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: A cosmetic anti-wrinkle performance testing device that facilitates 3D benchmarking features a multi-layered adaptive support structure formed by a support component and an adjustment component. The support component utilizes an elastic forehead fitting and a multi-area contact design with the chin. The adjustment component, through sliding movable arc blocks and symmetrical adjustment with forward and reverse screws, can flexibly adapt to the width and height of the chin according to the facial contours of different subjects. Combined with a flexible pad, it forms a continuous support surface, transforming the traditional single-point bearing of the tray into multi-area distributed bearing, reducing local pressure and minimizing discomfort for test subjects during prolonged testing. On the other hand, the light and shadow component, through a light strip structure linked to the elastic support pad, can automatically illuminate the chin and cheek depressions at a 45° angle, eliminating shadows caused by head obstruction and clearly presenting the skin texture and chin contour details in this area. This provides high-quality image data for the 3D scanning of the adjustment component, avoiding deviations in the evaluation of cosmetic anti-wrinkle performance due to insufficient 3D image analysis accuracy. At the same time, the cleaning component can clean the contact areas in a timely manner, further ensuring the cleanliness of the testing environment and the accuracy of the data.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3 As shown, this embodiment of the invention provides a cosmetic anti-wrinkle performance testing device that facilitates three-dimensional benchmarking. It includes a placement platform 1, on which a control component 2 is mounted. The control component 2 includes an arc-shaped support platform 21 fixed to the placement platform 1, and a semi-circular track 22 fixed on the support platform 21. The semi-circular design of the track 22 adapts to the curvature of the facial contour, providing a path for the circular movement of the sliding block 23. The sliding block 23 is slidably mounted on the track 22 via multiple symmetrically arranged pulleys 231. These pulleys 231 reduce friction between the sliding block 23 and the track 22, ensuring the smoothness and stability of the sliding block 23 as it slides along the track 22. Furthermore, a horizontal vertical support is provided on the sliding block 23. The first moving module 24 is perpendicular to the track 22. The first moving module 24 includes a concave support frame 241 fixed on the sliding block 23. A lead screw 242 is mounted on the support frame 241. One end of the lead screw 242 passes through the support frame 241 and is fixed to a turntable 245. The turntable 245 allows the operator to manually rotate the lead screw 242, which drives the sliding seat 244 to move through the threaded transmission. The sliding seat 244 is threadedly connected to the lead screw 242. Guide rods 243 are fixed on the support frame 241 on both sides of the lead screw 242. The sliding seat 244 is simultaneously movably sleeved on the two sets of guide rods 243 to linearly limit the movement of the sliding seat 244.

[0021] Furthermore, a second moving module 25 is provided on the sliding seat 244. The second moving module 25 has a similar structure to the first moving module 24, and the second moving module 25 is vertically distributed with the first moving module 24, which is suitable for cooperating with the first moving module 24 to achieve two-dimensional position adjustment in the plane. Here, the sliding seat 244 of the second moving module 25 is defined as the second moving module 251. At the same time, a third moving module 26 is provided on the second moving module 251. The third moving module 26 has a similar structure to the first moving module 24, and the third moving module 26 is set vertically to adapt to different facial heights of the test subjects. Here, the sliding seat 244 of the third moving module 26 is defined as the third moving module 261. A horizontally set detection device 27 is fixed on the third moving module 261. The detection device 27, as the core detection component, performs three-dimensional scanning of the test subject's face through its built-in optical imaging system, capturing detailed information such as skin wrinkles and textures, and providing raw image data for the analysis of the anti-wrinkle performance of cosmetics.

[0022] like Figure 2 and Figures 4-5 As shown, a support assembly 3 is provided on the support platform 21. The support assembly 3 includes a mounting base 31 fixed on the support platform 21, and a fixing frame 32 fixed on both sides of the mounting base 31. The fixing frame 32 is arc-shaped to adapt to the forehead contour and is used to position the sides of the subject's forehead and limit the left and right swaying of the head. The two ends of the fixing frame 32 are used to contact the sides of the subject's forehead, and a fitting member 34 is movably inserted into one end of the fixing frame 32. The fitting member 34 has an extension shaft. The fitting member 34 is movably inserted into one end of the fixing frame 32 through the extension shaft, and a spring 33 is sleeved on the extension shaft. The two ends of the spring 33 are respectively connected to the side of the fitting member 34 and one end of the fixing frame 32. The fitting member 34 can adaptively fit the forehead shape of different subjects through the elastic action of the spring 33, thereby enhancing wearing comfort and positioning accuracy.

[0023] Furthermore, a support column 35 is movably inserted into the mounting base 31. One end of the support column 35 has a contact portion 36, and a second spring 351 is sleeved on the support column 35. The two ends of the second spring 351 are respectively connected to the bottom surface of the contact portion 36 and the upper surface of the mounting base 31 to provide initial support for the contact portion 36. The support column 35, in conjunction with the second spring 351, enables the elastic raising and lowering of the contact portion 36 to accommodate the chin height of different subjects. Two sets of symmetrically arranged arc-shaped members 37 are fixed on the contact portion 36, and are centered on the upper part of the contact portion 36. A sliding buckle plate 38 is provided, and a through-type open slide groove 361 for sliding the buckle plate 38 is provided on the contact part 36. A limiting groove 362 is connected to the open slide groove 361. At the same time, a limiting block (not shown in the figure) is fixed on the bottom surface of the buckle plate 38 near one end, which is used with the limiting groove 362. In actual use, a part of the subject's chin contacts the contact part 36 and a part of the subject's chin contacts the two sets of arc-shaped parts 37, forming a multi-area contact structure, increasing the contact area with the subject's chin, dispersing pressure and avoiding single-point pressure.

[0024] like Figures 6-7 and Figure 9As shown, an adjustment component 5 slides on the arc-shaped component 37. The adjustment component 5 includes movable arc blocks 51 with sliding fasteners on two sets of arc-shaped components 37. The movable arc blocks 51 are adapted to slide along the curvature of the arc-shaped component 37 to adjust according to the chin width of different subjects. A flexible pad one (not shown in the figure) is provided on the movable arc block 51, and a flexible pad two 54 is provided on the sliding fastener plate 38. The flexible pad one and the flexible pad two 54 are made of skin-friendly material and form a continuous support surface by overlapping and cooperating to disperse chin pressure and avoid local compression. Initially, the flexible pad one on the movable arc block 51 partially extends into the flexible pad two 54 from the side, and is integrally set upward at one end of the flexible pad two 54. There is an anti-slip raised pad 55, which increases the friction of hand operation. Opening slots (not shown in the figure) are provided on both sides of the flexible pad 2 54 for placing the flexible pad 1. So when the movable arc block 51 slides along the arc of the arc member 37, the flexible pad 1 partially slides out of the opening slot, but still supports the subject's chin in conjunction with the flexible pad 2 54. An elastic support pad 52 is hinged to one end of the movable arc block 51 by a torsion spring. At the same time, a contact member 511 is fixed on the mounting base 31, which is suitable for pushing the elastic support pad 52 to rotate along the hinge point with the movable arc block 51. The contact member 511 guides the elastic support pad 52 to fit the cheek area through contact with the elastic support pad 52, which can reduce the pressure on the chin.

[0025] Furthermore, a concave frame 58 is fixed to the bottom surface of the contact part 36. A forward and reverse threaded rod 591 is connected to the bearing inside the concave frame 58. One end of the forward and reverse threaded rod 591 passes through the concave frame 58 and is fixed to a rotating wheel 59. Two sets of slide blocks 510 are threaded onto the forward and reverse threaded rod 591. The forward and reverse threaded rod 591 drives the two sets of slide blocks 510 to move synchronously in opposite directions through rotation, achieving symmetrical adjustment of the movable arc block 51 to accommodate chins of different widths. A support rod 57 is vertically and movably installed on one side of the slide block 510, with one end of the support rod 57 passing through the concave frame 36. A concave frame 58 is provided, and a groove (not shown in the figure) is provided on the bottom surface of the concave frame 58 for the support rod 57 to move. A support block 56 is fixed at one end of the support rod 57. The support block 56 is connected to the side of the movable arc block 51. At the same time, a tension spring (not shown in the figure) is sleeved on the support rod 57. One end of the tension spring is connected to the bottom surface of the support block 56, and the other end is connected to the upper surface of the slide block 510. The tension spring forms an elastic tension structure by connecting the bottom surface of the support block 56 and the upper surface of the slide block 510 at both ends, and adapts to the movement adjustment of the movable arc block 51.

[0026] like Figures 8-10As shown, a light and shadow component 4 is provided on the bottom surface of both sets of movable arc blocks 51. The light and shadow component 4 includes a bracket 42 fixed to the bottom surface of the movable arc block 51, and a mounting shell 43 is hinged to one end of the bracket 42 by a torsion spring. A light strip 45 is embedded in the mounting shell 43. The light strip 45 is suitable for providing 45° side lighting to the chin and cheek hollow areas to eliminate shadows and clearly present skin texture details. A T-shaped groove (not shown in the figure) is opened on the side of the mounting shell 43, and a slider 46 is slidably arranged in the T-shaped groove. A spring 48 is fixed on the side of the slider 46. One end of spring 48 is connected to one end of the inner wall of the T-shaped groove. At the same time, switches 49 are fixed at both ends of the inner wall of the T-shaped groove. One set of switches 49 is located at the center of spring 48. This set of switches 49 is used to control the opening of the light strip 45, and the other set of switches 49 is used to control the closing of the light strip 45. Meanwhile, a pull rope 410 is connected to the slider 46 through a hanging ring 47, and a connector 41 connected to the other end of the pull rope 410 is fixed on the bottom surface of the elastic support 52. The pull rope 410 is used to convert the rotation of the elastic support 52 into the sliding motion of the slider 46, so as to realize the linkage control of the light strip 45.

[0027] In actual use, when the subject's chin is placed on the placement area consisting of two sets of movable arc blocks 51 and flexible pad 54, the spring 351 is compressed downward. At this time, the adjustment component 5 moves downward synchronously with the contact part 36. The elastic support pad 52 gradually contacts the contact member 511. The contact member 511 pushes the elastic support pad 52 to rotate around the hinge, triggering the pulling action of the pull rope 410 to push the elastic support pad 52 to rotate around the hinge, thereby driving the pull rope 410 to pull the slider 46 and simultaneously squeeze the spring 48 until the elastic support pad 52 is rotated into place. At this time, the mounting shell 43 drives the light strip 45 to lift upward, and the slider 46 simultaneously presses the switch 49. At this time, the light strip 45 is turned on. After the light strip 45 is lifted, it illuminates the chin and cheek depression area at a 45° angle, supplementing the light from both sides of the shadow and illuminating the depression area where the chin and cheek connect, so that the details such as the chin contour and skin texture are clearly presented.

[0028] like Figures 11-12As shown, a cleaning component 6 is provided on the side of the concave frame 58 for cleaning the surfaces of the movable arc block 51 and the elastic support pad 52 in the default state. The cleaning component 6 includes a concave frame 61 fixed to the side of the concave frame 58, and a lead screw 62 is connected to the concave frame 61 by a bearing. One end of the lead screw 62 passes through the concave frame 61 and is fixed to a rotating wheel 65. A translation block 63 is threaded onto the lead screw 62, and a vertical rod 64 is vertically installed on the translation block 63 near one side. One end of the vertical rod 64 is fixed to a mounting rod 67 by a fastener. The vertical rod 64 serves as a support component for the mounting rod 67 and cooperates with a spring 64. 6. The mounting rod 67 is elastically raised and lowered to adapt to cleaning surfaces of different heights. The bottom surface of the mounting rod 67 is provided with a wiping sponge (not shown in the figure). The wiping sponge can directly contact the surfaces of the movable arc block 51 and the elastic support pad 52 to remove residual skin oil or cosmetic residue. The mounting rod 67 is located in the open slide groove 361 and its upper surface is in contact with the bottom surface of the sliding plate 38. At the same time, a spring 66 is sleeved on the vertical rod 64. The two ends of the spring 66 are respectively connected to the upper surface of the translation block 63 and the lower surface of the mounting rod 67. The spring 66 provides an upward elastic force to the mounting rod 67, ensuring that the wiping sponge fits tightly with the cleaning surface and improving the cleaning effect.

[0029] In actual use, the sliding plate 38 is slid to open the sliding groove 361. Then, the vertical rod 64 is lifted to pull the sliding plate 38 out of the sliding groove 361. After the sliding groove 361 is opened, it provides space for the installation rod 67 to move, avoiding interference with the sliding plate 38 during cleaning. Then, the sliding plate 38 is reset. After that, the installation rod 67 is driven to clean the surface of the movable arc block 51 and the elastic support pad 52 in the default state by holding the rotating wheel 65. The rotation of the rotating wheel 65 drives the lead screw 62 to rotate, so that the translation block 63 drives the installation rod 67 to move back and forth, so as to achieve a comprehensive cleaning of the surface of the movable arc block 51 and the elastic support pad 52, ensuring the cleanliness of the support components before each test.

[0030] Working principle: First, the subject places their head on the support component 3, with both sides of the forehead contacting the fitting parts 34 of the fixed frame 32. The fitting parts 34 adapt to the forehead contour through the elasticity of spring 33, achieving initial head positioning. Simultaneously, the chin is placed in the support area formed by the contact part 36, the arc-shaped part 37, and the flexible pad 54. The movable arc block 51 can slide along the arc-shaped part 37, and with the superimposed support of the flexible pads 54, the pressure on the chin is distributed. The operator can rotate the rotating wheel 59, driving the forward and reverse threaded rods 591 to rotate, causing the two sets of slides 510 to move synchronously in opposite directions, thus adapting the movable arc block 51 to the chin width of different subjects. If further adjustment of the support height is needed, the elasticity of spring 351 can be used to make the contact part 36 adaptively rise and fall with the chin height.

[0031] Then, the control component 2 begins to operate: the operator can push the sliding block 23 to slide along the semi-circular track 22, and the pulley 231 reduces the sliding resistance, allowing the detection device 27 to adjust the detection angle around the face. At the same time, the turntable 245 is rotated, driving the lead screw 242 to rotate, causing the sliding seat 244 to move linearly along the guide rod 243, realizing the fine adjustment of the position of the detection device 27 in the first direction. Similarly, through the cooperation of the lead screws and sliding seats of the second moving module 25 and the third moving module 26, the position adjustment of the detection device 27 in the horizontal second direction and the vertical direction is completed respectively, ultimately making the detection lens of the detection device 27 precisely aligned with the facial area to be tested (such as wrinkles around the eyes).

[0032] At the same time, when the face presses down on the contact part 36, the elastic support pad 52 contacts the contact part 511 and rotates around the hinge. The pull rope 410 pulls the slider 46, compresses the spring 48 and triggers the switch 49, so that the light strip 45 is automatically turned on, illuminating the chin and cheek depression area with a 45° side light, eliminating shadows and clearly presenting skin texture details, providing sufficient and uniform lighting conditions for the three-dimensional scanning of the detection device 27.

[0033] After the testing device 27 is started, it performs a three-dimensional scan of the facial area to be tested using its built-in optical imaging system, capturing detailed information such as the depth, volume, and texture of skin wrinkles, and transmitting the image data to the accompanying analysis software. The software processes the image, quantifies various parameters of the wrinkles, and compares the scan data before and after the use of cosmetics to analyze the anti-wrinkle performance of the cosmetics and generate an objective test report.

[0034] After the test is completed, the operator slides the sliding plate 38 to open the opening groove 361, lifts the vertical rod 64 to disengage the sliding plate 38, and then resets the sliding plate 38. Then, the operator rotates the second rotating wheel 65, driving the second lead screw 62 to rotate, causing the translation block 63 to move the mounting rod 67 back and forth along the surface of the movable arc block 51 and the elastic support pad 52.
