[0049] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0050] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0051] The accessory body 1 and accessories disclosed herein can be applied to various scenarios. In some embodiments, the accessory body 1 and accessories disclosed herein are applied to extended reality (XR) scenarios. Extended reality refers to all real and virtual combined environments and human-computer interactions generated by computer technology and wearable devices, including virtual reality (VR), augmented reality (AR), and mixed reality (MR) and other forms. This disclosure can be used in conjunction with extended reality head-mounted devices in extended reality scenarios.

[0052] like Figures 1 to 2 As shown, this disclosure provides an accessory body 1, the height of which is less than the outline diameter of the projection surface. The projection of the accessory body 1 onto a plane perpendicular to the height direction of the accessory body 1 is the projection surface. The accessory body 1 has at least one first light-emitting element 101, and the light from the first light-emitting element 101 is emitted from the outer peripheral side of the accessory body 1.

[0053] Understandably, by setting the height of the accessory body 1 to be less than the outline diameter of the projection surface, the accessory body 1 has a flat structure, which facilitates the wearing of the accessory body 1. Furthermore, the accessory body 1 has at least one first light-emitting element 101. The light emitted by the first light-emitting element 101 is emitted from the outer periphery of the accessory body 1, which facilitates the tracking and positioning of the accessory body 1 by the light emitted by the first light-emitting element 101. Especially when the accessory body 1 is worn at a position far away from the head-mounted device and is attached to a certain part of the limb or at a special angle relative to the head-mounted device, the camera on the head-mounted device can still collect the light spot on the outer periphery of the accessory body 1 and track the position of the accessory body 1, thereby improving the accuracy of positioning and enhancing the user experience.

[0054] It should be noted that the first light-emitting element 101 can emit visible or invisible light to form a light spot or pattern. After the camera on the head-mounted device collects the light spot or pattern formed by the first light-emitting element 101, it can identify the relative position and / or posture of the accessory body 1 according to the relevant algorithm, thereby realizing the tracking of the accessory body 1.

[0055] Furthermore, the main body 1 of the accessory is equipped with an IMU sensor. The IMU sensor is mainly used to detect and measure acceleration and rotational motion. IMU stands for Inertial Measurement Unit. The IMU sensor works in conjunction with the first light-emitting element 101 to achieve more accurate tracking from data from the optical and inertial measurement units.

[0056] For example, in one specific implementation, refer to Figure 1 The main body of the accessory 1 is a disc-shaped structure, and the height of the main body of the accessory 1 is smaller than the diameter of the projected surface. This design makes the main body of the accessory 1 easy to wear and also aesthetically pleasing.

[0057] like Figure 2 As shown, in some embodiments, a first light-concentrating element 13 is provided on the accessory body 1 corresponding to each first light-emitting element 101, and the first light-concentrating element 13 has a light-concentrating cavity for light concentration.

[0058] Understandably, the first light-emitting element 101 is disposed in the focusing cavity of the first light-concentrating element 13. The light emitted by the first light-emitting element 101 can be focused through the focusing cavity, so as to avoid the light spot formed by the first light-emitting element 101 being too large and affecting the tracking and positioning, which is conducive to improving the accuracy of tracking and positioning through the first light-emitting element 101.

[0059] For example, in one specific implementation, the first light-concentrating element 13 may be selected as a foam with grooves.

[0060] In some embodiments, the accessory body 1 includes a body structure 11, wherein at least one first light-emitting element 101 is disposed on the top edge of the body structure 11, and the direction of light emission is inclined towards the outer periphery of the accessory body 1 relative to the height direction of the accessory body 1. And / or, wherein at least one first light-emitting element 101 is disposed on the outer periphery of the body structure 11.

[0061] In other words, there are three different forms of the arrangement of the first light-emitting element 101. One is that all the first light-emitting elements 101 are arranged on the top edge of the main body structure 11, and the light emission direction of the first light-emitting element 101 is inclined towards the outer periphery of the accessory body 1 relative to the height direction of the accessory body 1. Another is that all the first light-emitting elements 101 are arranged on the outer periphery of the main body structure 11. The third is that at least one first light-emitting element 101 is arranged on the top edge of the main body structure 11, and at least one first light-emitting element 101 is arranged on the outer periphery of the main body structure 11.

[0062] Understandably, when the first light-emitting element 101 is disposed on the top edge of the body structure 11, the light emitted by the first light-emitting element 101 can be captured not only on the top of the accessory body 1, but also on the outer periphery of the accessory body 1, thus providing a wider tracking range.

[0063] For example, in one specific implementation, refer to Figure 2 A first light-emitting element 101 is provided on the top edge of the main body structure 11, and a first light-emitting element 101 is also provided on the outer periphery of the main body structure 11. This arrangement, with the first light-emitting element 101 offset in the height direction of the main body structure 11, helps to increase the probability of tracking the light of the first light-emitting element 101, thereby improving the accuracy of tracking and positioning the accessory body 1.

[0064] like Figure 1 and Figure 2 As shown, the main body 1 of the above-mentioned accessory also includes a light-transmitting cover 12, which covers the main body structure 11.

[0065] Understandably, by providing a light-transmitting cover 12, the first light-emitting element 101 on the main body structure 11 can be protected without affecting the light emitted by the first light-emitting element 101.

[0066] For example, in one specific implementation, the first light-emitting element 101 is an infrared lamp, and the light-transmitting cover 12 allows infrared light to pass through. Alternatively, the light emitted by the first light-emitting element 101 may also be visible light, or invisible light other than infrared light, such as near-infrared light, in which case the light-transmitting cover 12 is configured accordingly based on the characteristics of the light emitted by the first light-emitting element 101.

[0067] In some embodiments, the shape of the first polygon formed by the lines connecting any three adjacent first light-emitting elements 101 is different. This facilitates the identification of the accessory body 1 and the determination of the pose of the accessory body 1 by the first polygon, especially when the accessory body 1 is used alone.

[0068] It should be noted that at least three adjacent first light-emitting elements 101 can be seen from any angle along the circumference of the accessory body 1. That is to say, at least three first light-emitting elements 101 can be seen from any angle along the circumference of the accessory body 1. Moreover, since the first polygons formed by any three adjacent first light-emitting elements 101 are all different, it is convenient to track and locate the accessory body 1 and determine the pose of the accessory body 1 through the first polygons.

[0069] The first light-emitting element 101 is configured as at least three adjacent elements forming the first polygon because at least three light-emitting elements 101 are required to calculate the relative pose of the accessory body 1 relative to the head-mounted device. Therefore, the first polygon is at least triangular.

[0070] In other embodiments, the accessory body 1 is used to connect with the accessory base 2. When the accessory body 1 is connected to the accessory base 2, the first polygonal shape formed by the lines connecting any three adjacent first light-emitting elements 101 is different.

[0071] Understandably, when the accessory body 1 and accessory base 2 are connected and used as a whole, the accessory base 2 may partially obscure the first light-emitting element 101. Therefore, the first polygon formed by the lines connecting any three adjacent first light-emitting elements 101 exposed at this time will have different shapes, thus enabling the tracking and positioning of the accessory body 1, and determining the pose of the accessory body 1 through the first polygon.

[0072] For example, in one specific implementation, refer to Figure 2The main body structure 11 is provided with eight first light-emitting elements 101, and the triangles formed by connecting any three adjacent first light-emitting elements 101 are all different in shape.

[0073] Understandably, the tracking and positioning of the accessory body 1 is performed by three adjacent first light-emitting elements 101. The three first light-emitting elements 101 can form three light spots, which are distributed in a triangular pattern. Since the shapes of the triangles formed by any three adjacent light spots are different, the position and pose of the accessory body 1 can be determined by recognizing the shape of the triangle.

[0074] For example, in one specific implementation, refer to Figure 3 The diameter of the main body structure 11 is 38mm. Eight first light-emitting elements 101 are provided on the main body structure 11. Five of the first light-emitting elements 101 are provided on the top edge of the main body structure 11, and the remaining three first light-emitting elements 101 are provided on the circumferential side of the main body structure 11. The projections of the eight first light-emitting elements 101 on the plane perpendicular to the central axis of the accessory body 1 do not overlap.

[0075] Specifically, refer to Figures 3 to 6 For ease of description, the eight first light-emitting elements 101 are respectively defined as light-emitting element one 1011, light-emitting element two 1012, light-emitting element three 1013, light-emitting element four 1014, light-emitting element five 1015, light-emitting element six 1016, light-emitting element seven 1017, and light-emitting element eight 1018. Among them, light-emitting elements one 1011, light-emitting element two 1012, light-emitting element three 1013, light-emitting element four 1014, and light-emitting element five 1015 are disposed on the top edge of the main body structure 11, light-emitting elements six 1016, light-emitting element seven 1017, and light-emitting element eight 1018 are disposed on the circumferential side of the main body structure 11, with light-emitting element six 1016 located between light-emitting elements one 1011 and light-emitting element two 1012, light-emitting element seven 1017 located between light-emitting elements one 1011 and light-emitting element five 1015, and light-emitting element eight 1018 located between light-emitting elements two 1012 and light-emitting element three 1013.

[0076] Reference Figure 3The length of the line connecting light-emitting element 1011 and light-emitting element 2012 is 22.52 mm, the length of the line connecting light-emitting element 2012 and light-emitting element 3013 is 20.72 mm, the length of the line connecting light-emitting element 3013 and light-emitting element 4014 is 13.32 mm, the length of the line connecting light-emitting element 4014 and light-emitting element 51015 is 13.32 mm, and the length of the line connecting light-emitting element 51015 and light-emitting element 1011 is 22.52 mm. The angle formed by the line connecting light-emitting element 1011 and light-emitting element 2012 and the line connecting light-emitting element 2012 and light-emitting element 3013 is 94.43°. The angle formed by the line connecting light-emitting element 2012 and light-emitting element 3013 and the line connecting light-emitting element 3013 and light-emitting element 4014 is 114.72°. The angle formed by the line connecting light-emitting element 3013 and light-emitting element 4014 and the line connecting light-emitting element 4014 and light-emitting element 5015 is 130.57°. The angle formed by the line connecting light-emitting element 4014 and light-emitting element 5015 and the line connecting light-emitting element 5015 and light-emitting element 1011 is 110.29°. The angle formed by the line connecting light-emitting element 5015 and light-emitting element 1011 and the line connecting light-emitting element 1011 and light-emitting element 2012 is 90°.

[0077] Reference Figure 4 The length of the line connecting light-emitting element 1011 and light-emitting element 6 1016 is 12.03 mm, and the length of the line connecting light-emitting element 6 1016 and light-emitting element 2 1012 is 14.81 mm. The angle formed by the line connecting light-emitting element 1011 and light-emitting element 6 1016 and the line connecting light-emitting element 1011 and light-emitting element 2 1012 is 37.02°, the angle formed by the line connecting light-emitting element 1011 and light-emitting element 6 1016 and the line connecting light-emitting element 6 1016 and light-emitting element 2 1012 is 113.71°, and the angle formed by the line connecting light-emitting element 6 1016 and light-emitting element 2 1012 and the line connecting light-emitting element 1011 and light-emitting element 2 1012 is 29.27°.

[0078] Reference Figure 5The length of the line connecting light-emitting element 5 (1015) and light-emitting element 7 (1017) is 14.81 mm, and the length of the line connecting light-emitting element 1 (1011) and light-emitting element 7 (1017) is 12.03 mm. The angle formed by the line connecting light-emitting element 5 (1015) and light-emitting element 7 (1017) and light-emitting element 7 (1017) and light-emitting element 1 (1011) is 113.71°; the angle formed by the line connecting light-emitting element 1 (1011) and light-emitting element 7 (1017) and light-emitting element 1 (1011) and light-emitting element 5 (1015) is 37.02°; the angle formed by the line connecting light-emitting element 5 (1015) and light-emitting element 6 (1016) and light-emitting element 5 (1015) and light-emitting element 1 (1011) is 29.27°.

[0079] It should be noted that although the triangle formed by light-emitting elements 1011, 1012, and 1016 has three sides of 22.52mm, 14.81mm, and 12.03mm respectively, the triangles formed by light-emitting elements 1015, 1017, and 1011 are in different positions when viewed from the same angle, and therefore the two triangles are not the same.

[0080] Reference Figure 6 The length of the line connecting light-emitting element 2 (1012) and light-emitting element 8 (1018) is 12.30 mm, and the length of the line connecting light-emitting element 8 (1018) and light-emitting element 3 (1013) is 12.30 mm. The angle formed by the line connecting light-emitting element 2 (1012) and light-emitting element 8 (1018) and the line connecting light-emitting element 8 (1018) and light-emitting element 3 (1013) is 114.73°; ​​the angle formed by the line connecting light-emitting element 2 (1012) and light-emitting element 8 (1018) and the line connecting light-emitting element 2 (1012) and light-emitting element 3 (1013) is 32.64°; the angle formed by the line connecting light-emitting element 8 (1018) and light-emitting element 3 (1013) and the line connecting light-emitting element 3 (1013) and light-emitting element 2 (1012) is 32.64°.

[0081] In summary, the arrangement of the eight first light-emitting elements 101 on the main body structure 11 ensures that at least three adjacent first light-emitting elements 101 are visible from any angle, whether viewed circumferentially or from above, and the triangles formed by any three adjacent first light-emitting elements 101 are all different. Of course, the arrangement of the eight first light-emitting elements 101 can be adjusted according to actual needs.

[0082] like Figure 7 and Figure 8 As shown in the present disclosure, an accessory is also provided, which includes the accessory body 1 and the accessory base 2.

[0083] Reference Figure 8 In some embodiments, the accessory base 2 is connected to the accessory body 1, and at least one second light-emitting element 202 is provided on the accessory base 2. The at least one second light-emitting element 202 and at least one first light-emitting element 101 are connected to form a second polygon.

[0084] Understandably, by setting a second light-emitting element 202 on the accessory base 2, at least one second light-emitting element 202 and at least one first light-emitting element 101 are connected to form a second polygon, so that when the accessory base 2 and the accessory body 1 are connected, the accessory can be tracked and positioned by the first light-emitting element 101 on the accessory body 1 and the second light-emitting element 202 on the accessory base 2.

[0085] In some embodiments, the accessory base 2 has at least a first side and a second side, which are arranged opposite to each other, and each of the first and second sides has at least one second light-emitting element 202. The line connecting at least one second light-emitting element 202 on the first side and at least one first light-emitting element 101 forms a second polygon, and the line connecting at least one second light-emitting element 202 on the second side and at least one first light-emitting element 101 forms a second polygon. The two second polygons are the same in size and shape.

[0086] In other words, on the first and second sides of the accessory base 2, the second light-emitting element 202 on the accessory base 2 and the first light-emitting element 101 on the accessory body 1 can form two second polygons of the same size and shape. This allows for various wearing methods of the accessory, and tracking and positioning of the accessory can be achieved on both the first and second sides of the accessory base 2. In other words, there are two directions; the user does not need to worry about the installation orientation of the accessory body 1 and / or the accessory base 2. Regardless of how the accessory body 1 and accessory base 2 are installed, two identical second polygons can be formed on the first and second sides, thus the tracking algorithm for the accessory remains the same.

[0087] For example, in one specific implementation, at least two second light-emitting elements 202 on the first side of the accessory base 2 and one first light-emitting element 101 form a second polygon. By using only one first light-emitting element 101, the distance between two adjacent second light-emitting elements 202 on the accessory base 2 can be increased, making the shortest side of the second polygon larger than the longest side of any first polygon. In this way, the second light-emitting elements 202 on the accessory base 2 and the first light-emitting element 101 on the accessory body 1 can be used to achieve long-distance tracking and positioning of the accessory; and the first light-emitting element 101 on the accessory body 1 can be used to achieve short-distance tracking and positioning, improving the problem of light spot adhesion when the accessory performs long-distance tracking and positioning.

[0088] For example, in one specific implementation, refer to Figure 7The accessory base 2 has two second light-emitting elements 202 on both the first and second sides. The triangle formed by the two second light-emitting elements 202 on the first side and one first light-emitting element 101 is the same in size and shape as the triangle formed by the two second light-emitting elements 202 on the second side and one first light-emitting element 101.

[0089] Understandably, the two second light-emitting elements 202 on the first side and the two second light-emitting elements 202 on the second side of the accessory base 2 are symmetrically arranged about a reference plane, and the two first light-emitting elements 101 that participate in forming the second polygon are also symmetrically arranged about the aforementioned reference plane, so that the two second polygons formed are the same in size and shape.

[0090] It should be noted that the above-mentioned light-emitting element 2 1012 and light-emitting element 5 1015 are symmetrically arranged on the main body structure 11. The light-emitting element 5 1015 and the two second light-emitting elements 202 on the first side of the accessory base 2 form a triangle, and the light-emitting element 2 1012 and the two second light-emitting elements 202 on the second side of the accessory base 2 form a triangle. The shape and size of these two triangles are the same.

[0091] Reference Figure 7 In some embodiments, a second light-concentrating element 26 is provided on the accessory base 2 for each second light-emitting element 202, and the second light-concentrating element 26 has a light-concentrating cavity for concentrating light.

[0092] Understandably, the second light-emitting element 202 is disposed in the focusing cavity of the second light-concentrating element 26. The light emitted by the second light-emitting element 202 can be focused through the focusing cavity, so as to avoid the light spot formed by the second light-emitting element 202 being too large and affecting the tracking and positioning, which is conducive to improving the accuracy of the second light-emitting element 202 in tracking and positioning.

[0093] For example, in one specific implementation, the second focusing element 26 may be selected as a foam with grooves.

[0094] For example, in one specific implementation, the accessory can be a wearable device, such as a body tracker. The accessory body 1 is provided with a first light-emitting element 101, and the accessory base 2 is provided with a second light-emitting element 202. The accessory body 1 and the accessory base 2 can be used together to be strapped to the user's legs, waist, arms, etc. The accessory body 1 can also be used independently as a gaming peripheral on equipment such as baseball bats and ping-pong paddles.

[0095] like Figure 8 and Figure 9 As shown, in some embodiments, the accessory base 2 includes a connected outer shell 211 and an inner shell 212, with a mounting cavity 201 formed between the outer shell 211 and the inner shell 212, and the second light-emitting element 202 located in the mounting cavity 201.

[0096] Specifically, the outer shell 211 has a U-shaped structure. The two sides of the U-shaped structure in the width direction are the first side and the second side of the accessory base 2, respectively. The two second light-emitting elements 202 on the first side and the second side are respectively arranged at both ends in the length direction of the U-shaped structure. The second light-emitting elements 202 on the first side and the second side are symmetrically arranged in the width direction of the U-shaped structure. This helps to ensure the consistency of the second polygon formed by the second light-emitting elements 202 on the first side and the second side and the first light-emitting element 101 on the accessory body 1.

[0097] Furthermore, the inner shell 212 also has a U-shaped structure. The inner shell 212 and the outer shell 211 are fastened together to form the aforementioned accessory base 2, and the aforementioned mounting cavity 201 is formed between the inner shell 212 and the outer shell 211.

[0098] It should be noted that the second light-emitting element 202 and the second light-concentrating element 26 are both mounted on the outer shell 211, and the inner shell 212 allows the light emitted by the second light-emitting element 202 to pass through.

[0099] For example, in one specific implementation, the second light-emitting element 202 is an infrared lamp, in which case the inner shell 212 allows infrared light to pass through. Alternatively, the light emitted by the second light-emitting element 202 may also be visible light, or invisible light other than infrared light, such as near-infrared light, in which case the inner shell 212 is configured accordingly based on the characteristics of the light emitted by the second light-emitting element 202.

[0100] In some embodiments, the accessory body 1 and the accessory base 2 are detachably connected, and at least a portion of the outer peripheral side of the accessory body 1 is exposed. Thus, after the accessory base 2 and the accessory body 1 are connected, it facilitates the emission of light from the first light-emitting element 101, preventing the accessory base 2 from blocking the light emitted by the first light-emitting element 101.

[0101] It should be noted that the accessory body 1 and accessory base 2 can be detachably connected in various ways, such as by screw connection, magnetic connection, snap-fit ​​connection, etc.

[0102] like Figures 8 to 11 As shown, in some embodiments, the accessory body 1 is provided with a first plug-in member 111 and a first snap-fit ​​member 121; the accessory base 2 includes a base body 21, a second plug-in member 22, and a snap-fit ​​structure 23. The second plug-in member 22 is rotatably disposed on the base body 21 and can be plugged into the first plug-in member 111. The snap-fit ​​structure 23 can snap into or disengage from the first snap-fit ​​member 121. When the first plug-in member 111 and the second plug-in member 22 are plugged in, the accessory body 1 is pressed, causing the second plug-in member 22 to rotate so that the first snap-fit ​​member 121 snaps into the snap-fit ​​structure 23.

[0103] It is understood that by providing a first connector 111 and a first snap-fit ​​121 on the accessory body 1, the accessory base 2 includes a second connector 22 rotatably mounted on the base body 21 and a snap-fit ​​structure 23 capable of engaging or disengaging from the first snap-fit ​​121. When the first connector 111 and the second connector 22 are inserted, the accessory body 1 is pressed, causing the second connector 22 to rotate so that the first snap-fit ​​121 engages with the snap-fit ​​structure 23. This allows the accessory body 1 and the accessory base 2 to be connected as a single unit through insertion and snap-fit. Furthermore, the accessory body 1 and the accessory base 2 can be disengaged by the first snap-fit ​​121 and the snap-fit ​​structure 23, and the accessory body 1 and the accessory base 2 can be disassembled by detaching the first connector 111 and the second connector 22, thereby allowing the accessory body 1 to be used independently and expanding its application scenarios.

[0104] In some embodiments, the first connector 111 and the second connector 22 are both electrical connectors, which are used to realize signal transmission and / or electrical transmission between the accessory body 1 and the accessory base 2.

[0105] The first connector 111 and the second connector 22 described above can be male and female connectors that can simultaneously achieve electrical connection, such as USB and Type-C connectors. Alternatively, the first connector 111 and the second connector 22 can also be male and female connectors that can achieve electrical connection, such as Anderson connectors.

[0106] For example, in one specific implementation, refer to Figure 9 and Figure 10 Alternatively, the second connector 22 can be an electrical connector, such as a Type-C male connector, and the first connector 111 can also be an electrical connector, such as a Type-C female connector. When the first connector 111 and the second connector 22 are connected, not only is the main body 1 and the base 2 of the accessory connected, but electrical and signal transmission between them is also achieved. Alternatively, the first connector 111 can be a Type-C male connector, and the second connector 22 can be a Type-C female connector.

[0107] For example, in one specific implementation, when the first connector 111 and the second connector 22 are electrical connectors, the first light-emitting element 101 or the second light-emitting element 202 is electrically transmitted by the electrical connectors. This eliminates the need for additional wiring and simplifies the structure of the accessory body 1 and the accessory base 2.

[0108] Optionally, in other embodiments, connectors 25 are provided on both the accessory base 2 and the accessory body 1. When the first snap-fit ​​member 121 and the snap-fit ​​structure 23 are snapped together, the two connectors 25 are connected to realize signal transmission and / or electrical transmission between the accessory base 2 and the accessory body 1.

[0109] The connector 25 described above can be a wired or wireless transmission structure capable of signal transmission. Wired transmission structures include Pogo Pin, while wireless transmission structures include NFC, RFID, and Bluetooth. Alternatively, the connector 25 can also be a structure capable of electrical transmission, such as a wired electrical connection or wireless charging.

[0110] For example, in one specific implementation, the first light-emitting element 101 or the second light-emitting element 202 can be electrically powered by the connector 25. Furthermore, in this case, the first connector 111 and the second connector 22 can only achieve the insertion of the accessory body 1 and the accessory base 2, without the functions of electrical and signal transmission. For instance, one of the first connector 111 and the second connector 22 may be a plug-in post, and the other a plug-in hole; in this case, the insertion of the first connector 111 and the second connector 22 only achieves a structural connection. Alternatively, the first connector 111 and the second connector 22 may also have the functions of electrical and / or signal transmission.

[0111] For example, in another specific implementation, the first light-emitting element 101 and / or the second light-emitting element 202 may be electrically transmitted by the first connector 111 and the second connector 22, while the connector 25 may or may not have the functions of electrical transmission and signal transmission.

[0112] Understandably, when the first connector 111 and the second connector 22 are engaged and the connector 25 are present, the electrical and / or signal transmission between the accessory body 1 and the accessory base 2 can be more flexible, and a connection method with better electrical characteristics can be selected.

[0113] For example, in one specific implementation, refer to Figure 9 The connector 25 on the main body 1 is located on the bottom surface of the main body 1, that is, the surface of the main body 1 that contacts the base body 21 when the first snap-fit ​​member 121 and the snap-fit ​​structure 23 are snapped together. The connector 25 on the base 2 is positioned corresponding to the connector 25 on the main body 1. In this way, after the main body 1 and the base 2 are assembled, the two connectors 25 are connected, which is convenient for operation. The main body 1 and the base 2 can also shield the two connectors 25 to provide protection for them.

[0114] In some embodiments, at least one of the accessory body 1 and the accessory base 2 is provided with a power supply capable of supplying power to the first light-emitting element 101 and the second light-emitting element 202.

[0115] In one specific implementation, a power supply component can be provided on the accessory base 2. When the first latching member 121 and the second latching member 231 are engaged, the power supply component and the first light-emitting element 101 are connected, and the power supply component supplies power to the first light-emitting element 101. Alternatively, a power supply component can be provided on the accessory body 1. When the first latching member 121 and the second latching member 231 are engaged, the power supply component and the second light-emitting element 202 are connected, and the power supply component supplies power to the second light-emitting element 202. Alternatively, power supply components can be provided on both the accessory body 1 and the accessory base 2, wherein the power supply component on the accessory body 1 supplies power to the first light-emitting element 101, and the power supply component on the accessory base 2 supplies power to the second light-emitting element 202.

[0116] It should be noted that either the first snap-fit ​​element 121 or the snap-fit ​​structure 23 can be a snap-fit ​​protrusion and a snap-fit ​​hole, respectively. When the main body 1 of the accessory is pressed, the snap-fit ​​protrusion can deform and insert into the snap-fit ​​hole. Alternatively, both the first snap-fit ​​element 121 and the snap-fit ​​structure 23 can be snap-fit ​​protrusions, and at least one of the two snap-fit ​​protrusions can undergo elastic deformation to achieve snap-fit ​​or disengagement.

[0117] like Figures 9 to 11 In some embodiments, the snap-fit ​​structure 23 includes a second snap-fit ​​member 231 and a driving component. The second snap-fit ​​member 231 is slidably disposed on the base body 21. The second snap-fit ​​member 231 has a snap-fit ​​position that can snap-fit ​​with the first snap-fit ​​member 121 and an unlock position that can disengage from the first snap-fit ​​member 121. The driving component can drive the first snap-fit ​​member 121 to switch between the snap-fit ​​position and the unlock position.

[0118] Understandably, the engagement or disengagement of the second connector 231 with the first connector 121 can be achieved through the cooperation of the drive component and the second connector 231, thereby enabling the accessory body 1 to be detached from the accessory base 2 for separate use.

[0119] In some embodiments, the drive component includes a first elastic member 232, one end of which is connected to the base body 21 and the other end is connected to a second snap-fit ​​member 231. In its natural state, the second snap-fit ​​member 231 is in the snap-fit ​​position.

[0120] Understandably, in its natural state, the second snap-fit ​​component 231 is in the snap-fit ​​position, that is, when the accessory body 1 and the accessory base 2 are connected as one unit, the second snap-fit ​​component 231 and the first snap-fit ​​component 121 are in a snap-fit ​​state. By providing the first elastic element 232, a force can be applied to the second snap-fit ​​component 231, so that the first snap-fit ​​component 121 and the second snap-fit ​​component 231 are stably snapped together.

[0121] Furthermore, the first snap-fit ​​component 121 or the second snap-fit ​​component 231 is provided with a guide arc surface. When the accessory body 1 is pressed, the accessory body 1 can pass over the second snap-fit ​​component 231 through the guide arc surface and snap into the second snap-fit ​​component 231.

[0122] In other words, by setting a guide arc surface, the accessory body 1 can slide along the guide arc surface when pressed, reducing friction and facilitating the accessory to pass over the second locking member 231. Furthermore, during the sliding of the accessory body 1 along the guide arc surface, the second locking member 231 compresses the first elastic member 232. Thus, after the accessory body 1 passes over the guide arc surface, the force of the first elastic member 232 restoring its original shape pushes the second locking member 231 against the first locking member 121, achieving the locking of the first locking member 121 and the second locking member 231. Therefore, after the accessory body 1 and the accessory base 2 are connected by the first insertion member 111 and the second insertion member 22, simply pressing the accessory body 1 and moving it through the first elastic member 232 is sufficient to achieve the locking of the accessory body 1 and the accessory base 2, without any additional operation.

[0123] For example, in one specific implementation, refer to Figure 10 and Figure 11 The second snap-fit ​​component 231 is provided with a guide arc surface. When the accessory body 1 is pressed, the accessory body 1 slides along the guide arc surface on the second snap-fit ​​component 231 and pushes the second snap-fit ​​component 231 to compress the first elastic component 232.

[0124] For example, in one specific implementation, refer to Figure 8 , Figure 10 and Figure 11 The first snap-fit ​​component 121 is a snap-fit ​​hole. When the first snap-fit ​​component 121 and the second snap-fit ​​component 231 snap-fit ​​together, the second snap-fit ​​component 231 extends into the snap-fit ​​hole. Alternatively, the first snap-fit ​​component 121 can also be a protrusion provided on the accessory body 1.

[0125] In addition, it should be noted that the aforementioned card holes are located on the light-transmitting cover 12.

[0126] Furthermore, the drive assembly also includes a drive member 233, which has a first inclined surface, and a second snap-fit ​​member 231 has a second inclined surface that fits against the first inclined surface; when the drive member 233 moves down along the second inclined surface, it can drive the second snap-fit ​​member 231 to move from the snap-fit ​​position to the unlock position and compress the first elastic member 232.

[0127] In other words, when the first latching member 121 and the second latching member 231 are latched, the second latching member 231 is in the latched position. If it is necessary to disassemble the accessory body 1 and the accessory base 2, the driving member 233 can be driven to move downward along the second inclined plane, thereby driving the second latching member 231 from the latched position to the unlocked position and compressing the first elastic member 232. After the second latching member 231 disengages from the first latching member 121, the accessory body 1 can be disassembled. After the driving member 233 loses its external force, the force of the first elastic member 232 returning to its original state will drive the second latching member 231 from the unlocked position to the latched position. During this process, the driving member 233 moves upward along the second inclined plane.

[0128] It should be noted that, in order to improve the snapping effect of the first snap-fit ​​member 121 and the second snap-fit ​​member 231, the first elastic member 232 can be set to be in a compressed state when the second snap-fit ​​member 231 is in the snap-fit ​​position. In this way, the elastic force of the first elastic member 232 can be used to enhance the force between the second snap-fit ​​member 231 and the first snap-fit ​​member 121, thereby improving the snap-fit ​​stability.

[0129] Furthermore, such as Figure 10 and Figure 11 As shown, the base body 21 has a mounting cavity 201, the first elastic member 232 is located in the mounting cavity 201, the driving member 233 has one end of the first inclined surface located in the mounting cavity 201 and the other end located outside the mounting cavity 201, and the second inclined surface on the second snap-fit ​​member 231 is located in the mounting cavity 201.

[0130] In other words, when it is necessary to disassemble the accessory body 1 and the accessory base 2, pressing the end of the drive member 233 located outside the mounting cavity 201 causes the drive member 233 to move down along the second inclined surface, which drives the second snap-fit ​​member 231 to move inside the mounting cavity 201 from the snap-fit ​​position to the unlock position, making it easy to operate.

[0131] Lord Figure 10 and Figure 11 As shown, in some embodiments, the base body 21 has a receiving cavity 2121 capable of accommodating the accessory body 1. A portion of the second insert 22 is located within the receiving cavity 2121, and when the second snap-fit ​​231 is in the snap-fit ​​position, a portion of the second snap-fit ​​231 is located within the receiving cavity 2121. By providing the receiving cavity 2121, protection can be provided for the accessory body 1, and the overall thickness of the accessory can be reduced to a certain extent, which is beneficial for the miniaturization design of the accessory.

[0132] Specifically, the guide arc surface on the second snap-fit ​​member 231 is located inside the receiving cavity 2121 when the second snap-fit ​​member 231 is in the snap-fit ​​position.

[0133] For example, in one specific implementation, the depth of the receiving cavity 2121 can be set to be less than the height of the accessory body 1. This allows the top of the accessory body 1 to protrude from the accessory base 2, facilitating the tracking of the light-emitting part inside the accessory body 1 and making it easier to grasp the accessory body 1 when disassembling the accessory body 1 and accessory base 2. Furthermore, having the top of the accessory body 1 protruding from the accessory base 2 also facilitates cleaning of the accessory body 1. Alternatively, the depth of the receiving cavity 2121 can also be set to be equal to the height of the accessory body 1, thus fully enclosing the sides of the accessory body 1 and improving the protection of the accessory body 1.

[0134] In some embodiments, in the height direction of the accessory body 1, the heights of the first plug-in member 111 and the first snap-fit ​​member 121 are both less than half the height of the accessory body 1.

[0135] In other words, both the first connector 111 and the first snap-fit ​​connector 121 are located below half the height of the accessory body 1. This allows the depth of the receiving cavity 2121 to be less than the height of the accessory body 1, so that the upper part is exposed after the accessory body 1 and the accessory base 2 are connected. This makes it easier to hold the upper part of the accessory body 1 for insertion or disassembly, saves on the installation material of the accessory base 2, and facilitates the exposure of the first light-emitting element 101 on the accessory body 1, so as to track the first light-emitting element 101 on the accessory body 1.

[0136] like Figure 8 , Figure 10 and Figure 11 As shown, the inner shell 212 of the base body 21 has the aforementioned receiving cavity 2121, and the inner shell 212 is provided with a first through hole for the second plug-in member 22 to pass through and a second through hole for the second snap-fit ​​member 231 to pass through.

[0137] In other words, the base body 21 is composed of an outer shell 211 and an inner shell 212, with the inner shell 212 having the aforementioned receiving cavity 2121. Furthermore, the aforementioned mounting cavity 201 is formed between the outer shell 211 and the inner shell 212, thereby providing mounting space for the snap-fit ​​structure 23.

[0138] It should be noted that, in this case, when the accessory body 1 and the accessory base 2 are connected by the connector 25, the connector 25 is disposed on the outer shell 211, and the inner shell 212 has a hole for the connector 25 located on the accessory body 1 to pass through, or the connector 25 on the accessory base 2 to extend into the receiving cavity 2121. In this way, after the accessory body 1 and the accessory base 2 are assembled, the two connectors 25 can be avoided from being exposed, which is not only aesthetically pleasing, but also protects the connectors 25.

[0139] like Figures 9 to 11As shown, in some embodiments, the accessory base 2 further includes a second elastic element 24, which deforms and provides a lifting force for the second connector 22 to rotate and lift the accessory body 1 away from the accessory base 2.

[0140] In other words, when the first snap-fit ​​connector 121 and the second snap-fit ​​connector 231 disengage, under the action of the second elastic member 24, the second plug-in connector 22 will lift the accessory body 1 away from the accessory base 2. Thus, when disassembling the accessory body 1 and the accessory base 2, after the first snap-fit ​​connector 121 and the second snap-fit ​​connector 231 disengage, the accessory body 1 is lifted by the second plug-in connector 22, which makes it easier to disengage the accessory body 1 and the accessory base 2, and in other words, it makes it easier to remove the accessory body 1 from the second plug-in connector 22.

[0141] Furthermore, the second connector 22 is rotatably connected to the base body 21 via a pivot.

[0142] For example, in one specific implementation, the second elastic element 24 is selected as a torsion spring. The second elastic element 24 is sleeved on the rotating shaft, and the two free ends of the torsion spring are respectively connected to or abut against the second connector 22 and the base body 21. During the assembly of the accessory body 1 and the accessory base 2, when the accessory body 1 is pressed and the second connector 22 rotates, the second elastic element 24 undergoes elastic deformation. When the first latching member 121 and the second latching member 231 disengage, the force of the second elastic element 24 restoring its original shape drives the second connector 22 to rotate in the opposite direction, lifting the accessory body 1 away from the accessory base 2.

[0143] For example, in another specific implementation, the second elastic element 24 can also be a column spring, with one end connected to the base body 21 and the other end connected to the second connector 22. When the second latching member 231 and the first latching member 121 are engaged, the column spring is stretched. When the second latching member 231 disengages from the first latching member 121, the force of the column spring restoring its original shape causes the second connector 22 to rotate and lift the accessory body 1.

[0144] It should be noted that the second connector 22 has a first position and a second position under the action of the second elastic member 24. In its natural state, the second connector 22 is located in the first position. When the second latching member 231 disengages from the first latching member 121, the second connector 22 moves from the second position to the first position under the action of the second elastic member 24, thereby lifting the accessory body 1. When the second connector 22 is located in the first position and is inserted with the first connector 111, pressing the accessory body 1 towards the accessory base 2 causes the second connector 22 to rotate, causing the second latching member 231 and the first latching member 121 to engage. At this time, the second connector 22 is located in the second position, and the second elastic member 24 deforms, generating a force that can drive the second connector 22 to move from the second position to the first position.

[0145] Specifically, refer to Figure 10 The second latching member 231 engages with the first latching member 121. That is, when the second latching member 231 is in the latching position, the second inserting member 22 is in the second position, at which time the second inserting member 22 forms a first preset angle with the bottom surface of the receiving cavity 2121. (Refer to...) Figure 11 When the second connector 22 is in the first position, the second connector 22 and the bottom surface of the receiving cavity 2121 have a second preset angle, which is greater than the first preset angle.

[0146] For example, in one specific implementation, the first preset angle is 0°, meaning that when the second connector 22 is in the first position, it is parallel to the bottom surface of the receiving cavity 2121. The second preset angle is greater than 0° and less than 90°, so that when the second connector 22 is in the second position, it is convenient for the first connector 111 on the accessory body 1 to be inserted into or detached from the second connector 22.

[0147] Furthermore, referring to Figure 10 The second connector 22 is provided with a limiting part 221, and the base body 21 is provided with a limiting surface 2111. The limiting surface 2111 is used to limit the limiting part 221 when the second connector 22 lifts the accessory body 1.

[0148] In other words, when the second connector 22 lifts the main body 1 of the accessory under the action of the second elastic member 24, the limiting part 221 and the limiting surface 2111 cooperate to limit the position of the second connector 22. Specifically, when the second connector 22 is in the first position, the limiting part 221 and the limiting surface 2111 abut, that is, the limiting surface 2111 and the limiting part 221 cooperate to make the second connector 22 rotate to the first position and then stop rotating under the action of the second elastic member 24.

[0149] It should be noted that the aforementioned limiting surface 2111 is provided on the outer shell 211 and is located inside the outer shell 211.

[0150] In summary, the specific disassembly and assembly process of this component is explained in detail:

[0151] When the accessory body 1 and accessory base 2 are not installed, that is, when the accessory body 1 and accessory base 2 are in their natural state, the second plug 22 is in the first position, the second snap-fit ​​231 is in the snap-fit ​​position, and the limiting part 221 on the second plug 22 abuts against the limiting surface 2111.

[0152] 1. When installing the main body of accessory 1, first connect the second connector 22 and the first connector 111. At this time, the second connector 22 is in the first position and supports the main body of accessory 1, such as... Figure 11 As shown. Then, press the accessory body 1 towards the accessory base 2 to rotate the second connector 22 until the accessory body 1 contacts the guide arc surface of the second snap-fit ​​connector 231; continue pressing the accessory body 1 so that it passes over the guide arc surface and the second snap-fit ​​connector 231 engages with the first snap-fit ​​connector 121. At this point, the second connector 22 is in the second position, and the second snap-fit ​​connector 231 is in the snap-fit ​​position, thus achieving the installation of the accessory body 1, as shown. Figure 10 As shown.

[0153] It should be noted that during the sliding of the accessory body 1 along the guide arc surface, the second locking member 231 moves outward from the receiving cavity 2121 and compresses the first elastic member 232. After the accessory body 1 passes the guide arc surface, the first elastic member 232 pushes the second locking member 231 inward from the receiving cavity 2121, causing the second locking member 231 to press against the first locking member 121. During the process of pressing the accessory body 1 to rotate the second insertion member 22, the second elastic member 24 deforms and generates a force that drives the second insertion member 22 to move from the second position to the first position.

[0154] 2. When disassembling the main body 1 of the accessory, press the driving component 233, causing it to move downwards along the second inclined surface, driving the second latching component 231 from the latching position to the unlocking position. After the second latching component 231 and the first latching component 121 disengage, the second insertion component 22, under the action of the second elastic component 24, rotates from the second position to the first position to lift the main body 1 of the accessory away from the accessory base 2, until the second insertion component 22 moves to the first position, such as... Figure 11 As shown.

[0155] When the second connector 22 is rotated to the first position, the accessory body 1 is removed from the second connector 22, thus achieving the disassembly of the accessory body 1.

[0156] It should be noted that during the process of the driving member 233 driving the second latching member 231 to move from the latching position to the unlocking position, the second latching member 231 compresses the first elastic member 232. When the driving member 233 loses external force, the second latching member 231 returns to the latching position under the action of the first elastic member 232. During this process, the driving member 233 moves upward along the second inclined surface. When the second insertion member 22 rotates to the first position, the limiting part 221 on the second insertion member 22 abuts against the limiting surface 2111.
