Fig.16A schematic diagram of the three-dimensional structure of a third device for visual identification provided by an embodiment of the present disclosure is shown. The device for visual identification includes a base 1 and a movable member 2. The base 1 has a first pattern surface, and the movable member 2 has a second pattern surface. The movable member 2 can be movably arranged on the base 1, and the movable member 2 can move relative to the base 1 to adjust the relative position of the first pattern surface and the second pattern surface, so that the first pattern surface and the second pattern surface constitute different identification patterns. The device for visual identification provided by an embodiment of the present disclosure can flexibly form a variety of different identification patterns through one device by adjusting the position of the movable member 2, which is convenient for use and also saves materials.

[0035] In some embodiments of the present disclosure, see Figure 3 , Fig.10 and Fig.16 As shown, a receiving groove 122 is provided on the first pattern surface, and the movable member 2 can be movably provided in the receiving groove 122, and the movable member 2 has a second pattern surface exposed in the receiving groove 122. The movable member 2 can move in the receiving groove 122 to adjust the relative position of the second pattern surface and the first pattern surface, so that the first pattern surface and the second pattern surface form different identification patterns. The receiving groove 122 limits the range of movement of the movable member 2, so that the movable member 2 can only move in the receiving groove 122. It should be noted that Figure 3 In the embodiment, the movable member 2 at least covers a portion of the receiving groove 122 on the base 1 .

[0036] In an alternative embodiment, see Figure 3 and Fig.10 As shown, one surface of the base 1 along the thickness direction is the bottom surface, and the other surface of the base 1 along the thickness direction is the first pattern surface. Optionally, the first pattern surface at least includes an outer surface of the base 1 that is higher than the receiving groove 122, such as Figure 3 As shown. The identification surface is composed of at least the outer surface and the second pattern surface. Fig.10 As shown, the first pattern surface includes both the outer surface of the base 1 that is higher than the receiving groove 122 and the bottom surface of the receiving groove 122, that is, both the outer surface and the bottom surface have patterns. The identification pattern is composed of the outer surface, the second pattern surface and the exposed surface of the bottom wall that is not blocked by the movable part 2.

[0037] In some embodiments of the present disclosure, Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.11 , Fig.12 , Fig.15 , Fig.17 and Fig.18As shown, a plurality of first magnetic components a are arranged on the base 1, and at least one second magnetic component b is arranged on the movable member 2. When the movable member 2 moves to a plurality of designated positions in the receiving groove 122, the second magnetic component b is attracted to the first magnetic component a to form different identification patterns. When the movable member 2 moves to any designated position in the receiving groove 122, the second magnetic component b is magnetically positioned opposite to the first magnetic component a, and the first magnetic component a and the second magnetic component b are magnetically attracted to fix the position of the movable member 2, so that the device for visual identification can present a preset identification pattern. Moreover, the identification pattern formed can remain stable, and the identification pattern will not be changed due to the displacement of the movable member 2.

[0038] In some embodiments of the present disclosure, Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.11 , Fig.12 , Fig.15 , Fig.17 and Fig.18 As shown, the base 1 includes a bottom plate component 11 and a top plate component 12 that fit together. The top plate component 12 is formed with a slot 121. The slot 121 and the surface of the bottom plate component 11 close to the top plate component 12 form a receiving groove 122. A plurality of first magnetic components a are arranged on one of the bottom plate component 11 and the top plate component 12.

[0039] The bottom plate component 11 closes one end of the slot hole 121, so that a portion of the surface of the bottom plate component 11 close to the top plate component 12 constitutes the bottom surface of the receiving groove 122. Thus, the first pattern surface can be formed by at least one side of the top plate component 12 facing away from the bottom plate component 11 and the surface of the bottom end of the slot hole 121 on the bottom plate component 11.

[0040] Optionally, the first magnetic component a can be arranged on the top plate assembly 12. Each designated position of the receiving groove 122 can be located at a peripheral edge of the receiving groove 122, and each first magnetic component a can be arranged in sequence along the edge of the slot hole 121, respectively located at or close to the corresponding designated position. When the movable part 2 moves to any designated position, the second magnetic component b on the movable part 2 is magnetically attracted to the corresponding first magnetic component a on the top plate assembly 12. Alternatively, the first magnetic component a can also be arranged on the bottom plate assembly 11. Each first magnetic component a can be located in an area corresponding to the slot hole 121 on the bottom plate assembly 11, and each first magnetic component a is arranged in sequence along the circumference of the slot hole 121, respectively located at or close to the corresponding designated position. When the movable part 2 moves to any designated position, the second magnetic component b on the movable part 2 is magnetically attracted to the corresponding first magnetic component a on the bottom plate assembly 11.

[0041] In some embodiments of the present disclosure, Figure 4 , Fig. 9 and Fig.15 As shown, the bottom plate assembly 11 includes a bottom lower plate 111, a bottom upper plate 112 and a bottom middle plate 113. The bottom middle plate 113 is provided with a first through slot 1131, and the first through slot 1131 is used to accommodate the first magnetic component a. The bottom lower plate 111 and the bottom upper plate 112 are respectively arranged on both sides of the bottom middle plate 113 to enclose the first magnetic component a in the first through slot 1131. The first magnetic component a is located inside the bottom plate assembly 11 and is not exposed.

[0042] The bottom plate 111, the bottom upper plate 112 and the bottom middle plate 113 are stacked in sequence along the thickness direction, and the three form a sandwich structure, and the first magnetic component a is hidden in the bottom middle plate 113, which is conducive to the fixation of the first magnetic component a and also conducive to the appearance. The adjacent two of the bottom plate 111, the bottom upper plate 112 and the bottom middle plate 113 can be connected and fixed by any one of the following methods: clamping, bonding and fastener connection.

[0043] In some embodiments of the present disclosure, the cross section of the first through slot 1131 may be circular, and the cross section of the first magnetic component a is circular. Optionally, the outer diameter of the first magnetic component a matches the inner diameter of the first through slot 1131, and when the first magnetic component a is embedded in the first through slot 1131, the position is fixed and will not move along the radial direction of the first through slot 1131.

[0044] Optionally, the top plate assembly 12 covers the bottom upper plate 112. The outer diameter of the top plate assembly 12 and the outer diameter of the bottom upper plate 112 can be equal to completely cover the bottom upper plate 112; or, the outer diameter of the top plate assembly 12 and the outer diameter of the bottom upper plate 112 can also be different. The top plate assembly 12 can be a single-layer plate structure. The top plate assembly 12 and the bottom upper plate 112 can be connected and fixed by any one of the methods of clamping, bonding and fastener connection.

[0045] In some embodiments of the present disclosure, the surface of the bottom upper plate 112 is covered with a smooth coating, and the movable part 2 moves along the coating in the receiving groove 122. By providing a smooth coating on the surface of the bottom upper plate 112, the friction resistance of the movable part 2 when sliding is reduced, and the user can easily turn or push the movable part 2. Optionally, the bottom upper plate 112 can be made of white cardboard with a UV matte oil on the surface.

[0046] In some embodiments of the present disclosure, the bottom plate assembly 11 may not be provided with the bottom lower plate 111, that is, the bottom plate assembly 11 only includes the bottom upper plate 112 and the bottom middle plate 113, and the bottom middle plate 113 is provided with a receiving groove, and the receiving groove is used to accommodate the first magnetic component a. The bottom upper plate 112 covers the side of the bottom middle plate 113 close to the top plate assembly 12, and is used to support the movable part 2. Optionally, the receiving groove can be a blind groove, and the bottom upper plate 112 covers the notch of the upper surface of the bottom middle plate 113 that can close the blind groove. The receiving groove can also be a through groove, and the first magnetic component a can be bonded and fixed in the through groove.

[0047] In some embodiments of the present disclosure, Figure 4 , Fig. 9 and Fig.15 As shown, the movable member 2 includes a movable lower plate 21, a movable upper plate 22 and a movable middle plate 23. The movable middle plate 23 is provided with a second through groove 231, and the second through groove 231 is used to accommodate the second magnetic component b. The movable lower plate 21 and the movable upper plate 22 are respectively arranged on both sides of the movable middle plate 23 to enclose the second magnetic component b in the second through groove 231. The second magnetic component b is located inside the bottom plate assembly 11 and is not exposed. The movable lower plate 21, the movable upper plate 22 and the movable middle plate 23 are stacked in sequence along the thickness direction. The three are a sandwich structure, and the second magnetic component b is hidden in the movable middle plate 23. It is conducive to the fixation of the second magnetic component b and at the same time makes the appearance beautiful.

[0048] Optionally, any two adjacent ones of the movable lower plate 21 , the movable upper plate 22 and the movable middle plate 23 may be connected and fixed by any one of snap connection, bonding and fastener connection.

[0049] Optionally, the side of the movable upper plate 22 facing away from the movable lower plate 21 is a second pattern surface, and the second pattern surface is exposed in the receiving groove 122. The movable lower plate 21 is in contact with the bottom upper plate 112, and the surface of the movable lower plate 21 can be covered with a smooth coating. The movable part 2 moves along the bottom upper plate 112 in the receiving groove 122. By providing a smooth coating on the surface of the movable lower plate 21, the friction resistance of the movable part 2 when sliding is reduced, and the user can easily rotate or push the movable part 2. Preferably, the movable lower plate 21 can be made of white cardboard with UV matte oil on the surface.

[0050] In some embodiments of the present disclosure, the cross section of the second through slot 231 may be circular, and the cross section of the second magnetic component b is circular. Optionally, the outer diameter of the second magnetic component b matches the inner diameter of the second through slot 231, and when the second magnetic component b is embedded in the first through slot 1131, the position is fixed and will not move along the radial direction of the second through slot 231.

[0051] In some embodiments of the present disclosure, the movable member 2 may not be provided with a movable lower plate 21, that is, the movable member 2 only includes a movable upper plate 22 and a movable middle plate 23, and the movable upper plate 23 is provided with a receiving groove, and the receiving groove is used to accommodate the second magnetic component b. The movable upper plate 22 covers the upper surface of the movable middle plate 23. Optionally, the receiving groove can be a blind groove, and the movable upper plate 22 covers the notch of the movable middle plate 23 that can close the blind groove. Alternatively, the receiving groove can also be a through groove, and the second magnetic component b can be adhesively fixed in the through groove. The movable middle plate 23 is directly supported on the bottom upper plate 112. The cancellation of the movable lower plate 21 can reduce the magnetic force attenuation of the second magnetic component b, so that the magnetic force between the second magnetic component b and the first magnetic component a is greater.

[0052] In some embodiments of the present disclosure, Figures 1 to 6 As shown, the movable member 2 is rotatably disposed in the receiving groove 122, and the movable member 2 covers at least a portion of the receiving groove 122. The relative angle between the second pattern surface and the first pattern surface is adjusted by rotating the movable member 2 to form the different identification patterns. Optionally, the movable member 2 can rotate 360° in the receiving groove 122, while the base 1 is fixed. When the movable member 2 rotates at any angle, the second pattern surface on the movable member 2 and the first pattern surface on the base 1 can form different identification patterns.

[0053] In some embodiments of the present disclosure, the movable member 2 can rotate around the rotation axis in the receiving groove 122 to adjust the angle relative to the base 1, and the second pattern surface on the movable member 2 cooperates with the first pattern surface of the base 1 to form different identification patterns. Figure 3 shown.

[0054] Optionally, the movable member 2 may only cover a portion of the movable groove, and the first pattern surface also includes a portion of the groove bottom surface of the receiving groove 122 that is not blocked by the movable member 2. Alternatively, the movable member 2 may also completely cover the receiving groove 122.

[0055] In some embodiments of the present disclosure, the receiving groove 122 is a circular groove, and the movable member 2 is a circular sheet. Optionally, the outer diameter of the movable member 2 matches the outer diameter of the receiving groove 122, and the movable member 2 is embedded in the receiving groove 122. The receiving groove 122 has no exposed area, has a smooth and beautiful appearance, and is not easy to enter impurities and dirt.

[0056] In some embodiments of the present disclosure, Figure 4 , Figure 5 and Figure 6As shown, when the scheme of forming different identification patterns by rotating the movable part 2 is adopted, the first magnetic component a includes a first central magnetic component a1 and a plurality of first satellite magnetic components a2, the first central magnetic component a1 is located on the rotation axis of the movable part 2, and the first satellite magnetic components a2 are arranged equidistantly in sequence around the circumference of the first central magnetic component a1. The second magnetic component b includes a second central magnetic component b1 and a plurality of second satellite magnetic components b2, and the second satellite magnetic components b2 are arranged equidistantly in sequence around the circumference of the second central magnetic component b1, and the first central magnetic component a1 and the second central magnetic component b1 are positioned opposite to each other and magnetically attracted to each other. The connecting line of the first central magnetic component a1 and the second central magnetic component b1 is the rotation axis of the movable part 2, and the rotation axis is perpendicular to the bottom bracket 1. The first central magnetic component and the second magnetic component b are magnetically attracted to each other, and the magnetic attraction of the first central magnetic component and the second magnetic component b are used to enable the movable part 2 to rotate smoothly around the rotation axis without being easily deviated.

[0057] Alternatively, if Figure 5 and Figure 6 As shown, the first central magnetic component a1 is larger than each first satellite magnetic component a2. The second central magnetic component b1 is larger than each second satellite magnetic component b2. In this way, the magnetic attraction between the first central magnetic component a1 and the second central magnetic component b1 is greater than the magnetic attraction between the first satellite magnetic component a2 and the second satellite magnetic component b2. The movable component 2 is similar to a turntable, which uses the larger central magnetic component in the middle to rotate the axis, and uses the small satellite magnetic components around the central magnetic component to accurately position the turntable at different angles. When the movable component 2 rotates to a specified angle, at least part of the first satellite magnetic component a2 and the corresponding second satellite magnetic component b2 are opposite to each other and magnetically attracted to each other.

[0058] In some possible implementation schemes, the number of the first satellite magnetic parts a2 and the number of the second satellite magnetic parts b2 are not equal. That is, the number of the first satellite magnetic parts a2 and the number of the second satellite magnetic parts b2 are different. For example, when the number of the first satellite magnetic parts a2 is less than the second satellite magnetic parts b2, when the movable part 2 is rotated to a specified angle position, each second satellite magnetic part b2 is respectively opposite to a corresponding first satellite magnetic part a2, and is magnetically attracted to each other. By setting the number of the first satellite magnetic parts a2 and the number of the second satellite magnetic parts b2 to be different, the magnetic attraction between the movable part 2 and the base 1 can be appropriately reduced, the sliding resistance of the movable part 2 can be reduced, and the user can easily rotate the movable part 2. Optionally, the number of the first satellite magnetic parts a2 and the second satellite magnetic parts b2 can also be equal. Thereby, the movable part 2 can be more firmly stayed at the specified angle position on the base 1.

[0059] In some possible implementations, such as Figures 7 to 18As shown, the movable member 2 is movably disposed in the receiving groove 122, and the movable member 2 covers a portion of the receiving groove 122. By moving the movable member 2, the relative position of the second pattern surface and the first pattern surface can be adjusted to form the different identification patterns. The movable member 2 can slide in the receiving groove 122 to generate displacement, and by changing the position of the movable member 2 relative to the base 1, a variety of different identification patterns can be formed.

[0060] In some optional embodiments, the first pattern surface includes both the outer surface of the base 1 that is higher than the receiving groove 122 and the bottom surface of the receiving groove 122, that is, the first pattern surface is formed by the outer surface and the bottom surface of the groove. Optionally, both the outer surface and the bottom surface of the groove have patterns. The identification pattern is composed of the outer surface, the second pattern surface, and the exposed surface of the bottom surface of the groove that is not blocked by the movable part 2.

[0061] In some possible implementations, such as Fig.10 As shown, the receiving groove 122 has a plurality of limiting parts 1211, and the movable member 2 has a limiting matching part 24. The movable member 2 can move to any limiting part 1211 in the receiving groove 122. When the movable member 2 moves to each limiting part 1211, the limiting part 1211 and the limiting matching part 24 are limited and matched. At this time, the second pattern surface on the movable member 2 and the first pattern surface on the base 1 form an identification pattern. Under the cooperation of the limiting matching part and the limiting part, the movable member 2 will not be easily displaced, and the identification pattern is effective for a long time.

[0062] Optionally, a plurality of limiting fitting parts 24 can be provided along the circumferential direction of the movable part 2. When the movable part 2 is moved to any designated position, there is a limiting fitting part 24 on the movable part 2 that cooperates with a corresponding limiting part 1211 on the accommodating groove 122 to stably limit the movable part 2 at the designated position.

[0063] Optionally, the movable member 2 can be freely disposed in the receiving groove 122, so that the movable member 2 can translate and rotate in the receiving groove 122 to move to different areas. When the movable member 2 moves to any specified position, the movable member 2 and the corresponding limiting portion 1211 are limited and matched, and the movable member 2 is in a limited state. In this limited state, the position of the movable member 2 relative to the base 1 is unique, and the first pattern surface and the second pattern surface can form a unique identification pattern in combination.

[0064] In some possible implementations, such as Fig.10 As shown, the limiting portion 1211 may include at least one pair of adjacent limiting edges 1211a, and an angle is formed between the adjacent limiting edges 1211a; the limiting matching portion 24 may include at least one pair of adjacent limiting matching edges 241, and an angle is formed between the adjacent limiting matching edges 241; when the limiting portion 1211 and the limiting matching portion 24 are in the limiting matching state, the limiting matching edges 241 and the limiting edges 1211a are fitted together.

[0065] In the above embodiment, the angle between a pair of limiting edges 1211a of each limiting portion 1211 in the receiving groove 122 is equal to the angle between a pair of adjacent limiting matching edges 241 of the upper limiting matching portion 24 of the movable member 2. Thus, the movable member 2 can be stably limited at a specified position.

[0066] In some possible implementations, such as Fig.11 , Fig.12 , Fig.17 and Figure 8 As shown, a corresponding first magnetic component a is respectively provided on the base 1 corresponding to each limiting portion 1211. A second magnetic component b is provided on the movable member 2. When the movable member 2 moves to any limiting portion 1211, the magnetic component on the movable member 2 is magnetically attracted to the magnetic component corresponding to the limiting portion 1211 to fix the position of the movable member 2, prevent the movable member 2 from moving relative to the base 1, and make the current recognition pattern remain valid for a long time.

[0067] Optionally, the second magnetic component b can be located at the center of the movable part 2. A plurality of first magnetic components a are provided on the bottom of the receiving groove 122 on the bottom bracket 1, and each first magnetic component a is located at the bottom of the corresponding designated position. When the movable part 2 moves to the designated position, the position-limiting matching portion 24 on the movable part 2 is position-limited with the position-limiting portion 1211 on the receiving groove 122, and at the same time, the second magnetic component b on the movable part 2 and the corresponding first magnetic component a on the bottom bracket 1 are positioned opposite to each other and magnetically attracted to each other.

[0068] Fig.10 The structural diagram of a triangular device for visual identification is shown. The receiving slot 122 of the triangular device can be hexagonal.
