Description

Technical Field

[0001] This utility model relates to the field of auxiliary accessories for beauty instruments, and in particular to an adjustable chin support. Background Technology

[0002] In the field of facial beauty and skin health assessment, in order to accurately analyze the user's facial skin condition (such as moisture content, pigmentation, texture characteristics, etc.), it is often necessary to use professional facial skin detection instruments to collect images from multiple angles and analyze data, and to formulate personalized beauty treatment plans based on the test results. Existing instruments are usually equipped with a chin rest to fix the user's head position and ensure a consistent shooting reference. When it is necessary to collect images of the face from three angles—front, left, and right—in sequence according to the standard procedure, the user needs to manually adjust the head turning posture after each angle is captured to adapt to the next shooting angle. However, during repeated adjustments, the contact point and pressure between the chin and the support plate change with head rotation, making it difficult to maintain a precise consistency in the relative position and angle between the face and the lens. Furthermore, multiple adjustments can lead to human error, which directly results in deviations in the coordinate system, focal length, and lighting conditions between multiple shots. This leads to poor consistency and reduced comparability of image data, ultimately affecting the accuracy and reliability of skin condition analysis. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable chin support that can guide the user's head movement angle and reduce deviations in the relative position and angle of the face.

[0004] The technical solution adopted by the adjustable chin support disclosed in this utility model is as follows: The device includes a base and a connecting plate, the connecting plate being rotatably connected to the base. The top of the connecting plate has a contact portion, and the base has a groove. A limiting post extends from the connecting plate and moves within the groove. The groove constrains the rotation angle of the connecting plate. A first limiting groove and multiple second limiting grooves are formed within the groove, with the multiple second limiting grooves located on either side of the first limiting groove. Both the first and second limiting grooves are arranged along the moving path of the limiting post. The limiting post has an elastic component that can selectively engage with either the first or second limiting groove. Both the first and second limiting grooves are used to position the rotation angle of the connecting plate.

[0005] As a preferred embodiment, the limiting post is provided with an installation hole, and the elastic component includes an elastic element and a limiting element. Both the elastic element and the limiting element are placed in the installation hole, and the elastic element pushes the limiting element to selectively engage with the first limiting groove or the second limiting groove.

[0006] As a preferred embodiment, the groove is arc-shaped, and the center of the groove is located at the connection between the base and the connecting plate.

[0007] As a preferred embodiment, a sliding column extends from the base, and a sliding groove is provided on the connecting plate. The sliding groove is arc-shaped, and the center of the sliding groove is located at the connection between the base and the connecting plate.

[0008] The beneficial effects of the adjustable chin support disclosed in this utility model are: Install the base inside the skin detection instrument. When in use, rotate the connecting plate to reset it, so that the limiting post is positioned in the center of the groove. At the same time, the elastic component is inserted into the first limiting groove to achieve centered alignment of the contact part. The user places the chin on the contact part to complete the frontal facial image acquisition. The user then adjusts the head angle to capture the left side of the face. The chin rotates the connecting plate through the contact part, causing the elastic component to disengage from the first limiting groove and engage with the second limiting groove on one side of the first limiting groove, thereby positioning the head rotation angle and completing the capture of the left side of the face. When the head angle is adjusted to capture the right side of the face, the elastic component disengages from the current second limiting groove again and gets into the second limiting groove on the other side of the first limiting groove to position the head rotation angle, thereby completing the capture of the right side of the face. By using the rotating structure of the connecting plate on the base, the user can adjust the head angle horizontally, and guide the angle adjustment with the engagement mechanism of the elastic component and the first or second limiting groove, effectively reducing the position and angle error of facial acquisition.

[0014] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figures 1-4.

[0015] The present invention discloses an adjustable chin support, comprising a base 1 and a connecting plate 2; In this embodiment, the preferred base 1 includes a bracket 12 and a connecting plate 13. The connecting plate 13 is fixedly connected to the bracket 12 by bolts, and the bracket 12 is fixedly installed in the preset position of the skin detection instrument.

[0016] The connecting plate 2 is rotatably connected to the connecting plate 13 of the base 1. Three nuts 22 are embedded in the bottom of the connecting plate 2. The bottom of the connecting plate 13 is provided with a first screw. The first screw passes through the connecting plate 13 and is connected to one of the nuts 22. The connecting plate 2 is constrained to the connecting plate 13 and rotated by the first screw. Furthermore, by adjusting the tightness of the connection between the first screw and one of the nuts 22, the user can more easily adjust the head angle.

[0017] A groove 131 is provided on the base 1. The groove 131 is located on the top of the connecting plate 13. In this embodiment, the groove 131 is preferably arc-shaped, and the center of the groove 131 is located at the connection between the base 1 and the connecting plate 2. Furthermore, a limiting post 211 extends from the bottom of the connecting plate 2, and the limiting post 211 is placed in the groove 131; when the connecting plate 2 rotates on the connecting plate 13, it drives the limiting post 211 to move along the groove 131, and the groove 131 is used to constrain the maximum rotation angle of the connecting plate 2. Furthermore, a sliding column 132 extends from the base 1 and is located at the top of the connecting plate 13; a sliding groove 212 is provided at the bottom of the connecting plate 2. In this embodiment, the sliding groove 212 is preferably arc-shaped, and the center of the sliding groove 212 is located at the connection between the base 1 and the connecting plate 2; when the connecting plate 2 rotates on the connecting plate 13, it drives the sliding column 132 to move along the sliding groove 212, so as to keep the connecting plate 2 stable during rotation.

[0018] The groove 131 is provided with a first limiting groove 133 and a plurality of second limiting grooves 134. In this embodiment, it is preferred that there are two second limiting grooves 134, which are respectively located on both sides of the first limiting groove 133. The first limiting groove 133 and the second limiting groove 134 are arranged along the moving path of the limiting post 211. The second limiting groove 134 and the first limiting groove 133 form a 30° angle around the connection point between the base 1 and the connecting plate 2. Furthermore, in this embodiment, the cross-sections of the first limiting groove 133 and the second limiting groove 134 are preferably arc-shaped. This design can reduce the resistance to the release of the limiting member 24 when it is inserted into the first limiting groove 133 or the second limiting groove 134, but also allows the user to feel the segmentation of the limiting member 24 being inserted into the first limiting groove 133 or the second limiting groove 134. Furthermore, the limiting post 211 is provided with an elastic component, which can be selectively engaged in the first limiting groove 133 or the second limiting groove 134. Furthermore, the limiting post 211 is provided with a mounting hole, and the elastic component includes an elastic element 23 and a limiting element 24; both the elastic element 23 and the limiting element 24 are placed in the mounting hole, and the two ends of the elastic element 23 respectively abut against the bottom of the mounting hole and the limiting element 24. In this embodiment, the elastic element 23 is preferably made of silicone elastic material, so that the elastic element 23 can push the limiting element 24 to selectively engage in the first limiting groove 133 or the second limiting groove 134. The first limiting groove 133 and the second limiting groove 134 are both used to position the rotation angle of the connecting plate 2, and a positioning feedback is triggered once every 30° rotation. In this embodiment, the limiting element 24 is preferably spherical, which further reduces the resistance of the limiting element 24 when disengaging from the first limiting groove 133 or the second limiting groove 134, but also allows the user to feel the segmented feeling of the spherical limiting element 24 engaging in the first limiting groove 133 or the second limiting groove 134.

[0019] The top of the connecting plate 2 is provided with a contact part 3. In this embodiment, the contact part 3 preferably includes a connecting block 31 and a silicone pad 32. The top of the connecting block 31 is provided with two second screws. The two second screws pass through the connecting block 31 and are connected with two other nuts 22, thereby fixing the connecting block 31 to the top of the connecting plate 2. Furthermore, the silicone pad 32 is fitted onto the outside of the connecting block 31, and the user's chin contacts the silicone pad 32, avoiding direct contact between the connecting block 31 and the user's chin, thus reducing user discomfort during use.

[0020] Please refer to Figures 1-5 .

[0021] Before use, the connecting plate 2 needs to be rotated to reset so that the limiting post 211 is positioned in the center of the groove 131. At the same time, the elastic member 23 pushes the limiting member 24 into the first limiting groove 133 to achieve the center alignment of the contact part 3. During use, the user places their chin on the silicone pad 32, and the skin detection instrument completes the frontal facial image collection. Subsequently, the user adjusts the head angle to capture the left side of the face. The chin drives the connecting plate 2 to rotate through the contact part 3, and the limiting member 24 compresses the elastic member 23 and disengages from the first limiting groove 133. When the connecting plate 2 rotates to one side 30°, the elastic member 23 pushes the limiting member 24 into the second limiting groove 134 on one side of the first limiting groove 133. The tactile feedback when the limiting member 24 is engaged indicates that the angle adjustment is in place, and the skin detection instrument then captures the left side of the face. As the head angle is adjusted to capture the right side of the face, the limiting member 24 compresses the elastic member 23 again and disengages from the current second limiting groove 134. When the connecting plate 2 rotates to the other side 60°, the elastic member 23 pushes the limiting member 24 into the second limiting groove 134 on the other side of the first limiting groove 133. Similarly, the user is prompted to adjust to the correct position through a segmented feedback, and the skin detection instrument captures the right side of the face.

[0022] Continue adjusting the head angle. The lower jaw drives the connecting plate 2 to rotate to one side by 30° through the contact part 3, so that the connecting plate 2 is reset. The limiting member 24 is pushed into the first limiting groove 133 again under the push of the elastic member 23, completing the acquisition of the front, left and right sides of the face.

[0023] This utility model provides an adjustable chin support. The base is installed inside a skin detection instrument. When in use, the connecting plate is rotated and reset, so that the limiting post is positioned in the center of the groove. At the same time, the elastic component is inserted into the first limiting groove to achieve centered alignment of the contact part. The user places the chin on the contact part to complete the frontal facial image collection. The user then adjusts the head angle to capture the left side of the face. The chin rotates the connecting plate through the contact part, causing the elastic component to disengage from the first limiting groove and engage with the second limiting groove on one side of the first limiting groove, thereby positioning the head rotation angle and completing the capture of the left side of the face. When the head angle is adjusted to capture the right side of the face, the elastic component disengages from the current second limiting groove again and gets into the second limiting groove on the other side of the first limiting groove to position the head rotation angle, thereby completing the capture of the right side of the face. By using the rotating structure of the connecting plate on the base, the user can adjust the head angle horizontally, and guide the angle adjustment with the engagement mechanism of the elastic component and the first or second limiting groove, effectively reducing the position and angle error of facial acquisition.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
