[0049] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0051] The accessory body 1 and accessories disclosed in the present invention can be applied to various scenarios. In some embodiments, the accessory body 1 and accessories disclosed in the present invention 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, which include virtual reality VR, augmented reality AR, and mixed reality MR. The present invention can be used in conjunction with an extended reality head-mounted device in an extended reality scenario.

[0052] like Figure 1 to Figure 2 As shown, the present disclosure provides an accessory body 1, the height of the accessory body 1 is smaller than the contour diameter of the projection surface, the projection of the accessory body 1 on 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 of the first light-emitting element 101 is emitted from the outer peripheral side of the accessory body 1.

[0053] It can be understood that by setting the height of the accessory body 1 to be smaller than the outline diameter of the projection surface, the accessory body 1 has a flat structure, which is convenient for wearing the accessory body 1, and the accessory body 1 has at least one first light-emitting element 101, and the light of the first light-emitting element 101 is emitted from the outer peripheral side of the accessory body 1, which is convenient for tracking and positioning the accessory body 1 through the light of 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 fits to a certain part of the limbs or has a special angle relative to the head-mounted device, the camera on the head-mounted device can still capture the light spot on the outer peripheral side of the accessory body 1 and track the position of the accessory body 1, thereby improving the accuracy of positioning and improving the user experience.

[0054] It should be noted that the above-mentioned 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 with the accessory body 1 according to the relevant algorithm, and then realize the tracking of the accessory body 1.

[0055] Furthermore, the accessory body 1 is provided with an IMU sensor. The IMU sensor is a sensor mainly used to detect and measure acceleration and rotational motion. The full name of IMU is Inertial Measurement Unit. The IMU sensor cooperates with the above-mentioned first light-emitting element 101 to perform more accurate tracking from the data of the optical and inertial measurement units.

[0056] For example, in a specific implementation, referring to Figure 1 The accessory body 1 is a round pancake structure, and the height of the accessory body 1 is less than the diameter of the projection surface. This arrangement makes the accessory body 1 easy to wear and beautiful.

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

[0058] It can be understood that the first light-emitting element 101 is arranged in the focusing cavity of the first focusing member 13, and the focusing cavity can gather the light emitted by the first light-emitting element 101 to avoid the light spot formed by the first light-emitting element 101 being too large to affect the tracking and positioning, which is beneficial to improving the accuracy of tracking and positioning through the first light-emitting element 101.

[0059] For example, in a specific implementation, the first focusing element 13 may be selected to be 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 emission direction of the light is inclined toward 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] That is to say, there are three different forms of the setting position of the first light-emitting element 101. One is that the first light-emitting elements 101 are all set at the top edge of the main body structure 11, and the light emission direction of the first light-emitting element 101 is inclined toward the outer periphery of the accessory body 1 relative to the height direction of the accessory body 1; one is that the first light-emitting elements 101 are all set on the outer periphery of the main body structure 11; one is that at least one first light-emitting element 101 is set on the top edge of the main body structure 11, and at least one first light-emitting element 101 is set on the outer periphery of the main body structure 11.

[0062] It can be understood that when the first light-emitting element 101 is arranged at the top edge of the main structure 11, the light emitted by the first light-emitting element 101 can be captured not only at the top of the accessory body 1, but also at the outer peripheral side of the accessory body 1, and the tracking range is larger.

[0063] For example, in a specific implementation, referring to Figure 2 The top edge of the main body structure 11 is provided with a first light emitting element 101, and the outer peripheral side of the main body structure 11 is also provided with a first light emitting element 101. In this way, the first light emitting element 101 is staggered in the height direction of the main body structure 11, which is conducive to improving the probability of tracking the light of the first light emitting element 101, thereby facilitating improving the accuracy of tracking and positioning the accessory body 1.

[0064] like Figure 1 and Figure 2 As shown, the accessory body 1 further includes a light-transmitting cover 12 , and the light-transmitting cover 12 is covered on the main body structure 11 .

[0065] It is understandable that by providing the light-transmitting cover 12 , the first light-emitting element 101 on the main structure 11 can be protected without affecting the light emission of the first light-emitting element 101 .

[0066] For example, in a 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, etc. In this case, the light-transmitting cover 12 is set accordingly according to the characteristics of the light emitted by the first light emitting element 101.

[0067] In some embodiments, the first polygonal shapes formed by connecting any three adjacent first light emitting elements 101 are different. This facilitates identification of the accessory body 1 and determines the position of the accessory body 1 through 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 viewing angle on the circumference of the accessory body 1. In other words, at least three first light-emitting elements 101 can be seen from any viewing angle on the circumference of the accessory body 1, and since the first polygons formed by any at least three adjacent first light-emitting elements 101 are different, it is convenient to track and locate the accessory body 1, and determine the position and posture of the accessory body 1 through the first polygon.

[0069] The first light-emitting elements 101 are arranged to form at least three adjacent first light-emitting elements 101 to form a first polygon because the light spots or patterns formed by at least three first light-emitting elements 101 are required to calculate the relative position of the accessory body 1 relative to the head-mounted device. Therefore, the first polygon is at least a triangle.

[0070] In other embodiments, the accessory body 1 is used to connect to the accessory base 2. When the accessory body 1 is connected to the accessory base 2, the first polygonal shapes formed by the connecting lines of any adjacent at least three first light-emitting elements 101 exposed outside are different.

[0071] Understandably, when the accessory body 1 and the accessory base 2 are connected and used as a whole, the accessory base 2 may block part of the first light-emitting element 101. Therefore, the first polygonal shapes formed by the connecting lines of any three adjacent first light-emitting elements 101 exposed at this time are different, so that the tracking and positioning of the accessory body 1 can also be achieved, and the posture of the accessory body 1 can be determined by the first polygon.

[0072] For example, in a specific implementation, referring to Figure 2Eight first light-emitting elements 101 are arranged on the main body structure 11, and the triangle shapes formed by connecting any three adjacent first light-emitting elements 101 are different.

[0073] It can be understood that the tracking and positioning of the accessory body 1 is carried out through three adjacent first light-emitting elements. The three first light-emitting elements 101 can form three light spots. The three light spots are distributed in a triangular shape. Since the shapes of the triangles formed by any three adjacent light spots are different, the posture of the accessory body 1 can be determined by identifying the shape of the triangle.

[0074] For example, in a specific implementation, referring to Figure 3 The diameter of the main body structure 11 is 38 mm, and eight first light-emitting elements 101 are arranged on the main body structure 11, wherein five first light-emitting elements 101 are arranged at the top edge of the main body structure 11, and the remaining three first light-emitting elements 101 are arranged at the circumferential side of the main body structure 11, and 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 with each other.

[0075] Specifically, refer to Figures 3 to 6 For the convenience of description, the eight first light-emitting elements 101 are respectively defined as light-emitting element 1 1011, light-emitting element 2 1012, light-emitting element 3 1013, light-emitting element 4 1014, light-emitting element 5 1015, light-emitting element 6 1016, light-emitting element 7 1017 and light-emitting element 8 1018. Among them, light-emitting element 1 1011, light-emitting element 2 1012, light-emitting element 3 1013, light-emitting element 4 1014 and light-emitting element 5 1015 are arranged at the top edge of the main structure 11, light-emitting element 6 1016, light-emitting element 7 1017 and light-emitting element 8 1018 are arranged at the circumferential side of the main structure 11, and light-emitting element 6 1016 is located between light-emitting element 1 1011 and light-emitting element 2 1012, light-emitting element 7 1017 is located between light-emitting element 1 1011 and light-emitting element 5 1015, and light-emitting element 8 1018 is located between light-emitting element 2 1012 and light-emitting element 3 1013.

The angle formed by the connection line between the light emitting element 1011 and the light emitting element 6 1016 and the connection line between the light emitting element 1011 and the light emitting element 2 1012 is 37.02°, the angle formed by the connection line between the light emitting element 1011 and the light emitting element 6 1016 and the connection line between the light emitting element 6 1016 and the light emitting element 2 1012 is 113.71°, and the angle formed by the connection line between the light emitting element 6 1016 and the light emitting element 2 1012 and the connection line between the light emitting element 1011 and the light emitting element 2 1012 is 29.27°.

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

[0079] It should be noted that, although the lengths of the three sides of the triangle formed by light-emitting element one 1011, light-emitting element two 1012 and light-emitting element six 1016 and the triangle formed by light-emitting element five 1015, light-emitting element seven 1017 and light-emitting element one 1011 are 22.52 mm, 14.81 mm and 12.03 mm respectively, from the same viewing angle, the positions of the two triangles are different, and therefore the two triangles are not the same.

[0080] Reference Figure 6 , the length of the connection line between the second light emitting element 1012 and the eighth light emitting element 1018 is 12.30 mm, and the length of the connection line between the eighth light emitting element 1018 and the third light emitting element 1013 is 12.30 mm. The angle formed by the connection line between the second light emitting element 1012 and the eighth light emitting element 1018 and the connection line between the eighth light emitting element 1018 and the third light emitting element 1013 is 114.73°; ​​the angle formed by the connection line between the second light emitting element 1012 and the eighth light emitting element 1018 and the connection line between the second light emitting element 1012 and the third light emitting element 1013 is 32.64°; the angle formed by the connection line between the eighth light emitting element 1018 and the third light emitting element 1013 and the connection line between the third light emitting element 1013 and the second light emitting element 1012 is 32.64°.

[0081] In summary, the eight first light-emitting elements 101 are arranged on the main body structure 11 so that at least three adjacent first light-emitting elements 101 can be seen from any viewing angle in the circumferential direction or when viewed from above the main body structure 11, and the triangles formed by any three adjacent first light-emitting elements 101 are different. Of course, the arrangement of the above eight first light-emitting elements 101 can also be adjusted according to actual needs.

[0082] like Figure 7 and Figure 8 As shown, an embodiment of the present disclosure further provides an accessory, which includes the above-mentioned accessory body 1 and 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 disposed on the accessory base 2. The at least one second light-emitting element 202 and the at least one first light-emitting element 101 are connected to form a second polygon.

[0084] It can be understood that by setting the 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, the first side and the second side are arranged opposite to each other, and each of the first side and the second side corresponds to at least one second light-emitting element 202. The line connecting the at least one second light-emitting element 202 on the first side and the at least one first light-emitting element 101 forms a second polygon, and the line connecting the at least one second light-emitting element 202 on the second side and the at least one first light-emitting element 101 forms a second polygon, and the two second polygons have the same size and shape.

[0086] That is, on the first side and the second side 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, so that the accessory can be worn in various ways, and the tracking and positioning of the accessory can be achieved on the first side and the second side of the accessory base 2. That is to say, there are two directions, and the user does not need to care about the installation direction of the accessory body 1 and / or the accessory base 2. No matter how the accessory body 1 and the accessory base 2 are installed, they can form two identical second polygons on the first side and the second side, so the algorithm for tracking the accessory is the same.

[0087] For example, in a 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, so that the shortest side of the second polygon is greater than the longest side of any first polygon, so that the second light-emitting element 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; the first light-emitting element 101 on the accessory body 1 can be used to achieve short-distance tracking and positioning, and improve the problem of light spot adhesion when the accessory is performing long-distance tracking and positioning.

[0088] For example, in a specific implementation, referring to Figure 7Two second light-emitting elements 202 are provided on the first side and the second side of the accessory base 2, and the triangle formed by the two second light-emitting elements 202 on the first side and the one first light-emitting element 101 and the triangle formed by the two second light-emitting elements 202 on the second side and the one first light-emitting element 101 are of the same size and shape.

[0089] It can be understood that the two second light-emitting elements 202 on the first side of the accessory base 2 and the two second light-emitting elements 202 on the second side are symmetrically arranged with respect to a reference plane, and the two first light-emitting elements 101 participating in forming the second polygon are also symmetrically arranged with respect to the above-mentioned reference plane, so that the two second polygons formed have the same 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 structure 11, wherein 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, and the two triangles have the same shape and size.

[0091] Reference Figure 7 In some embodiments, a second light focusing member 26 is disposed on the accessory base 2 corresponding to each second light emitting element 202 , and the second light focusing member 26 has a light focusing cavity for focusing light.

[0092] It can be understood that the second light-emitting element 202 is arranged in the focusing cavity of the second focusing member 26. The focusing cavity can focus the light emitted by the second light-emitting element 202 to avoid the light spot formed by the second light-emitting element 202 being too large and affecting the tracking and positioning, which is beneficial to improving the accuracy of the tracking and positioning of the second light-emitting element 202.

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

[0094] For example, in a specific implementation, the accessory can be a wearable device, such as a body tracker, with a first light-emitting element 101 disposed on the accessory body 1, and a second light-emitting element 202 disposed on the accessory base 2. The accessory body 1 and the accessory base 2 can be used in combination to be tied to the user's legs, waist, arms, etc. The accessory body 1 can also be used alone as a gaming peripheral on equipment such as a baseball bat and a table tennis racket.

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

[0096] Specifically, the shell 211 is a U-shaped structure, and the two sides of the U-shaped structure in the width direction are respectively the first side and the second side of the accessory base 2, and the two second light-emitting elements 202 on the first side and the second side are respectively arranged at the two ends in the length direction of the U-shaped structure, and 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, which is conducive to ensuring 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 is also a U-shaped structure, and the inner shell 212 and the outer shell 211 are snap-fitted and connected to form the accessory base 2 , and the installation 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 focusing member 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 a specific implementation, the second light emitting element 202 is an infrared lamp, and 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, etc. In this case, the inner shell 212 is set accordingly according to 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 part of the peripheral side of the accessory body 1 is exposed. In this way, after the accessory base 2 and the accessory body 1 are connected, it is convenient for the light of the first light-emitting element 101 to be emitted, and the accessory base 2 is prevented from blocking the light emitted by the first light-emitting element 101.

[0101] It should be noted that there are various ways to achieve detachable connection between the accessory body 1 and the accessory base 2, such as screw connection, magnetic connection, snap connection, etc.

[0102] like Figures 8 to 11 As shown, in some embodiments, the accessory body 1 is provided with a first plug connector 111 and a first clamping member 121; the accessory base 2 includes a base body 21, a second plug connector 22 and a clamping structure 23, the second plug connector 22 is rotatably provided on the base body 21, and can be plugged and connected with the first plug connector 111, and the clamping structure 23 can be clamped or disengaged with the first clamping member 121. When the first plug connector 111 and the second plug connector 22 are plugged, the accessory body 1 is pressed to drive the second plug connector 22 to rotate so that the first clamping member 121 is clamped with the clamping structure 23.

[0103] It can be understood that, by providing the first plug connector 111 and the first clamping connector 121 on the accessory body 1, the accessory base 2 includes a second plug connector 22 rotatably provided on the base body 21 and a clamping structure 23 capable of being clamped or disengaged with the first clamping connector 121. When the first plug connector 111 and the second plug connector 22 are plugged in, the accessory body 1 is pressed to drive the second plug connector 22 to rotate so that the first clamping connector 121 is clamped with the clamping structure 23, so that the accessory body 1 and the accessory base 2 are connected as a whole through plugging and clamping, and the first clamping connector 121 and the clamping structure 23 can be disengaged, and the first plug connector 111 and the second plug connector 22 can be disengaged to disassemble the accessory body 1 and the accessory base 2, so that the accessory body 1 can be used alone, expanding the application scenario.

[0104] In some embodiments, the first connector 111 and the second connector 22 are both electrical connectors, and the electrical connectors are used to achieve 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 may be connectors that can distinguish between male and female and can achieve electrical connection at the same time, such as USB, Type-C, etc. Alternatively, the first connector 111 and the second connector 22 may also be connectors that can not distinguish between male and female but can achieve electrical connection, such as Anderson plugs, etc.

[0106] For example, in a specific implementation, referring to Fig. 9 and Fig.10 , the second connector 22 may be an electrical connector, such as a Type-C male connector, and the first connector 111 may also be an electrical connector, such as a Type-C female connector. After the first connector 111 and the second connector 22 are plugged in, not only the plug-in connection between the accessory body 1 and the accessory base 2 is realized, but also the electrical transmission and signal transmission between the accessory body 1 and the accessory base 2 is realized. Alternatively, the first connector 111 may be a Type-C male connector, and the second connector 22 may be a Type-C female connector.

[0107] For example, in a 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 connected to each other. This can save the need for additional wiring and simplify 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, and when the first clamping member 121 and the clamping structure 23 are clamped, 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 may be a wired transmission structure or a wireless transmission structure capable of signal transmission, such as a pogo pin, or a wireless transmission structure such as NFC, RFID, Bluetooth, etc. Alternatively, the connector 25 may be a structure capable of electrical transmission, such as a wired electrical connection or wireless charging.

[0110] For example, in a specific implementation, the first light-emitting element 101 or the second light-emitting element 202 can realize electrical transmission through the connector 25 to supply power to the first light-emitting element 101 and / or the second light-emitting element 202. Moreover, in this case, the first connector 111 and the second connector 22 can cooperate to only realize the plug-in connection between the accessory body 1 and the accessory base 2, but do not have the functions of electrical transmission and signal transmission. For example, one of the first connector 111 and the second connector 22 is a plug-in column and the other is a plug-in hole. At this time, when the first connector 111 and the second connector 22 are plugged in, only structural plug-in connection is realized. Alternatively, the first connector 111 and the second connector 22 also have the functions of electrical transmission and / or signal transmission.

[0111] Exemplarily, in another specific implementation, the first light-emitting element 101 and / or the second light-emitting element 202 can realize electrical transmission by the first connector 111 and the second connector 22, while the connector 25 does not have the function of electrical transmission and signal transmission or has the function of electrical transmission and / or signal transmission.

[0112] It is understandable that when the first connector 111 and the second connector 22 cooperate with the connector 25, the electrical transmission and / or signal transmission between the accessory body 1 and the accessory base 2 can be made more flexible, and a connection method with better electrical characteristics can be selected.

[0113] For example, in a specific implementation, referring to Fig. 9 The connector 25 on the accessory body 1 is located on the bottom surface of the accessory body 1, that is, on the side of the accessory body 1 that contacts the base body 21 when the first clamping member 121 and the clamping structure 23 are clamped. The connector 25 on the accessory base 2 is arranged corresponding to the position of the connector 25 on the accessory body 1, so that after the accessory body 1 and the accessory base 2 are assembled in place, the two connectors 25 are connected, which is convenient for operation, and the accessory body 1 and the accessory base 2 can cover the two connectors 25 to provide protection for the connectors 25.

[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 a specific implementation, a power supply may be provided on the accessory base 2. When the first clamping member 121 and the second clamping member 231 are clamped, the power supply and the first light-emitting element 101 are turned on, and the power supply supplies power to the first light-emitting element 101. Alternatively, a power supply may be provided on the accessory body 1. When the first clamping member 121 and the second clamping member 231 are clamped, the power supply and the second light-emitting element 202 are turned on, and the power supply supplies power to the second light-emitting element 202. Alternatively, power supplies may be provided on both the accessory body 1 and the accessory base 2, wherein the power supply on the accessory body 1 supplies power to the first light-emitting element 101, and the power supply on the accessory base 2 supplies power to the second light-emitting element 202.

[0116] It should be noted that one of the first clamping member 121 and the clamping structure 23 may be a clamping protrusion, and the other may be a clamping hole, and when the accessory body 1 is pressed, the clamping protrusion may be deformed and inserted into the clamping hole. Alternatively, both the first clamping member 121 and the clamping structure 23 may be clamping protrusions, and at least one of the two clamping protrusions may be elastically deformed to achieve clamping or disengagement.

[0117] like Figures 9 to 11 In some embodiments, the clamping structure 23 includes a second clamping member 231 and a driving assembly. The second clamping member 231 is slidably disposed on the base body 21. The second clamping member 231 has a clamping position capable of being clamped with the first clamping member 121 and an unlocking position capable of being disengaged from the first clamping member 121. The driving assembly can drive the first clamping member 121 to switch between the clamping position and the unlocking position.

[0118] Understandably, the second clamping member 231 can be engaged or disengaged from the first clamping member 121 through the cooperation between the driving assembly and the second clamping member 231 , thereby enabling the accessory body 1 to be removed from the accessory base 2 and used separately.

[0119] In some embodiments, the driving assembly includes a first elastic member 232 , one end of the first elastic member 232 is connected to the base body 21 , and the other end is connected to the second clamping member 231 . In a natural state, the second clamping member 231 is located at a clamping position.

[0120] Understandably, in the natural state, the second clamping member 231 is located at the clamping position, that is, when the accessory body 1 and the accessory base 2 are connected as one, the second clamping member 231 and the first clamping member 121 are in a clamping state. By providing the first elastic member 232, a force can be applied to the second clamping member 231, so that the first clamping member 121 and the second clamping member 231 are stably clamped.

[0121] Furthermore, a guiding arc surface is provided on the first clamping member 121 or the second clamping member 231 , and when the accessory body 1 is pressed, the accessory body 1 can pass over the second clamping member 231 through the guiding arc surface and be clamped on the second clamping member 231 .

[0122] That is to say, by providing the guide arc surface, the accessory body 1 can slide along the guide arc surface when pressed, reducing friction, making it easier for the accessory to pass over the second clamping member 231, and in the process of the accessory body 1 sliding along the guide arc surface, the second clamping member 231 compresses the first elastic member 232, so that after the accessory body 1 passes over the guide arc surface, the force of the first elastic member 232 to restore the original state pushes the second clamping member 231 to press against the first clamping member 121, thereby achieving the clamping of the first clamping member 121 and the second clamping member 231. Therefore, after the accessory body 1 and the accessory base 2 are plugged in through the first plug-in member 111 and the second plug-in member 22, the accessory body 1 and the accessory base 2 can be clamped in only by pressing the accessory body 1 through the movement of the first elastic member 232, without additional operation.

[0123] For example, in a specific implementation, referring to Fig.10 and Fig.11 A guide arc surface is provided on the second clamping member 231 . When the accessory body 1 is pressed, the accessory body 1 slides along the guide arc surface on the second clamping member 231 and pushes the second clamping member 231 to compress the first elastic member 232 .

[0124] For example, in a specific implementation, referring to Figure 8 , Fig.10 and Fig.11 The first clamping member 121 is a clamping hole. When the first clamping member 121 is clamped with the second clamping member 231, the second clamping member 231 extends into the clamping hole. Alternatively, the first clamping member 121 can also be a protrusion provided on the accessory body 1.

[0125] In addition, it should be noted that the above-mentioned clamping hole is arranged on the light-transmitting cover body 12 .

[0126] Furthermore, the driving assembly also includes a driving member 233, the driving member 233 has a first inclined surface, and the second clamping member 231 has a second inclined surface that fits the first inclined surface; when the driving member 233 moves downward along the second inclined surface, it can drive the second clamping member 231 to move from the clamping position to the unlocking position and compress the first elastic member 232.

[0127] That is to say, when the first clamping member 121 and the second clamping member 231 are clamped, the second clamping member 231 is at the clamping position. If the accessory body 1 and the accessory base 2 need to be disassembled, the driving member 233 can be driven to move downward along the second inclined plane to drive the second clamping member 231 to move from the clamping position to the unlocking position and compress the first elastic member 232. When the second clamping member 231 is disengaged from the first clamping member 121, the accessory body 1 can be disassembled, and after the driving member 233 loses the external force, the force of the first elastic member 232 to restore the original state will drive the second clamping member 231 to move from the unlocking position to the clamping position. In this process, the driving member 233 moves up along the second inclined plane.

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

[0129] Furthermore, if Fig.10 and Fig.11 As shown, the base body 21 has an installation cavity 201, the first elastic member 232 is located in the installation cavity 201, the driving member 233 has one end with a first inclined surface located in the installation cavity 201, and the other end is located outside the installation cavity 201, and the second inclined surface on the second clamping member 231 is located in the installation cavity 201.

[0130] That is to say, when the accessory body 1 and the accessory base 2 need to be disassembled, pressing the end of the driving member 233 located outside the installation cavity 201 causes the driving member 233 to move downward along the second inclined surface, thereby driving the second clamping member 231 to move in the installation cavity 201 from the clamping position to the unlocking position, which is convenient for operation.

[0131] Lord Fig.10 and Fig.11 As shown, in some embodiments, the base body 21 has a receiving cavity 2121 capable of receiving the accessory body 1, a portion of the second plug connector 22 is located in the receiving cavity 2121, and when the second clamping member 231 is located in the clamping position, a portion of the second clamping member 231 is located in the receiving cavity 2121. By providing the receiving cavity 2121, the accessory body 1 can be protected, and the overall thickness of the accessory can be reduced to a certain extent, which is conducive to the miniaturization design of the accessory.

[0132] Specifically, the guiding arc surface on the second clamping member 231 is located in the accommodating cavity 2121 when the second clamping member 231 is located at the clamping position.

[0133] For example, in a specific implementation, the depth of the accommodating cavity 2121 can be set to be less than the height of the accessory body 1. In this way, the accessory base 2 can be exposed from the top of the accessory body 1, which is convenient for tracking the light-emitting part in the accessory body 1 and for grabbing the accessory body 1 when disassembling the accessory body 1 and the accessory base 2. In addition, the top of the accessory body 1 is exposed from the accessory base 2, which is also convenient for cleaning the accessory body 1. Alternatively, the depth of the accommodating cavity 2121 can also be set to be equal to the height of the accessory body 1, so that the side of the accessory body 1 is fully wrapped, thereby improving the protection effect of the accessory body 1.

[0134] In some embodiments, in the height direction of the accessory body 1 , the heights of the first plug connector 111 and the first clip connector 121 are both less than half of the height of the accessory body 1 .

[0135] That is to say, the first plug connector 111 and the first clip connector 121 are both below half the height of the accessory body 1, which is conducive to setting the depth of the accommodating cavity 2121 to be less than the height of the accessory body 1, so that the upper half is exposed after the accessory body 1 and the accessory base 2 are connected. This makes it convenient to hold the upper half of the accessory body 1 for plugging or disassembly, saves installation materials for 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 , Fig.10 and Fig.11 As shown, the inner shell 212 of the base body 21 has the above-mentioned accommodating cavity 2121, and the inner shell 212 is provided with a first through hole for the second plug connector 22 to pass through and a second through hole for the second clamping connector 231 to pass through.

[0137] That is, the base body 21 is composed of an outer shell 211 and an inner shell 212, and the inner shell 212 has the above-mentioned accommodating cavity 2121. In addition, the above-mentioned installation cavity 201 is formed between the outer shell 211 and the inner shell 212, thereby providing an installation space for the clamping structure 23.

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

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

[0140] That is to say, when the first clamping member 121 and the second clamping member 231 are disengaged, under the action of the second elastic member 24, the second plug-in member 22 will lift the accessory body 1 away from the accessory base 2, so that when the accessory body 1 and the accessory base 2 are disassembled, after the first clamping member 121 and the second clamping member 231 are disengaged, the accessory body 1 is lifted by the second plug-in member 22, which facilitates the disengagement of the accessory body 1 and the accessory base 2, that is, facilitates the removal of the accessory body 1 from the second plug-in member 22.

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

[0142] For example, in a specific implementation, the second elastic member 24 is selected as a torsion spring, the second elastic member 24 is sleeved on the rotating shaft, and the two free ends of the torsion spring are respectively connected or abutted against the second plug-in connector 22 and the base body 21. During the assembly process of the accessory body 1 and the accessory base 2, when the accessory body 1 is pressed to drive the second plug-in connector 22 to rotate, the second elastic member 24 is elastically deformed. When the first clamping member 121 and the second clamping member 231 are disengaged, the force of the second elastic member 24 to restore the original state drives the second plug-in connector 22 to rotate in the opposite direction to lift the accessory body 1 away from the accessory base 2.

[0143] For example, in another specific implementation, the second elastic member 24 can also be selected as a column spring, one end of which is connected to the base body 21, and the other end is connected to the second plug-in connector 22. When the second clip 231 is engaged with the first clip 121, the column spring is stretched. When the second clip 231 is disengaged from the first clip 121, the force of the column spring to restore the original state causes the second plug-in 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 the natural state, the second connector 22 is located at the first position. When the second clamping member 231 is disengaged from the first clamping member 121, the second connector 22 moves from the second position to the first position under the action of the second elastic member 24 to lift the accessory body 1. When the second connector 22 is located at the first position and is plugged with the first connector 111, the accessory body 1 is pressed toward the accessory base 2 to rotate the second connector 22, so that the second clamping member 231 and the first clamping member 121 are plugged. At this time, the second connector 22 is located at the second position, and the second elastic member 24 is deformed to generate a force that can drive the second connector 22 to move from the second position to the first position.

[0145] Specifically, refer to Fig.10 , the second clamping member 231 is clamped with the first clamping member 121, that is, when the second clamping member 231 is in the clamping position, the second plug-in member 22 is in the second position, and at this time, the second plug-in member 22 and the bottom surface of the accommodating cavity 2121 form a first preset angle. Fig.11 When the second connector 22 is located at the first position, the second connector 22 and the bottom surface of the accommodating cavity 2121 have a second preset angle, and the second preset angle is greater than the first preset angle.

[0146] For example, in a specific implementation, the first preset angle is 0°, that is, when the second connector 22 is in the first position, it is parallel to the bottom surface of the accommodating 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 plugged in or out of the second connector 22.

[0147] Further, refer to Fig.10 A limiting portion 221 is provided on the second connector 22 , and a limiting surface 2111 is provided on the base body 21 . The limiting surface 2111 is used to limit the limiting portion 221 when the second connector 22 lifts the accessory body 1 .

[0148] That is, when the second connector 22 lifts the accessory body 1 under the action of the second elastic member 24, the limiting portion 221 and the limiting surface 2111 cooperate to limit the position of the second connector 22. Specifically, when the second connector 22 is located at the first position, the limiting portion 221 abuts against the limiting surface 2111, that is, the limiting surface 2111 cooperates with the limiting portion 221 so that the second connector 22 rotates to the first position under the action of the second elastic member 24, and then stops rotating.

[0149] It should be noted that the limiting surface 2111 is disposed on the outer shell 211 and is located on the inner side of the outer shell 211 .

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

[0151] When the accessory body 1 and the accessory base 2 are not installed, that is, when the accessory body 1 and the accessory base 2 are each in a natural state, the second connector 22 is located at the first position, the second clamping member 231 is located at the clamping position, and the limiting portion 221 on the second connector 22 abuts against the limiting surface 2111.

[0152] 1. When installing the accessory body 1, first plug the second connector 22 and the first connector 111 together. At this time, the second connector 22 is located at the first position and supports the accessory body 1. Fig.11 Then, the accessory body 1 is pressed toward the accessory base 2 to rotate the second connector 22 until the accessory body 1 contacts the guide arc surface of the second clamping member 231; the accessory body 1 is pressed continuously to make the accessory body 1 pass over the guide arc surface and the second clamping member 231 clamps with the first clamping member 121. At this time, the second connector 22 is located at the second position and the second clamping member 231 is located at the clamping position, so that the accessory body 1 is installed. Fig.10 shown.

[0153] It should be noted that, when the accessory body 1 slides along the guide arc surface, the second clamping member 231 moves toward the outside of the accommodating cavity 2121 and compresses the first elastic member 232. After the accessory body 1 passes over the guide arc surface, the first elastic member 232 pushes the second clamping member 231 to move toward the inside of the accommodating cavity 2121 so that the second clamping member 231 is pressed against the first clamping member 121. When the accessory body 1 is pressed to rotate the second plug-in member 22, the second elastic member 24 is deformed and generates a force that drives the second plug-in member 22 to move from the second position to the first position.

[0154] 2. When removing the accessory body 1, press the driving member 233 so that the driving member 233 moves downward along the second inclined surface to drive the second clamping member 231 to move from the clamping position to the unlocking position. After the second clamping member 231 and the first clamping member 121 are disengaged, the second plug-in member 22 rotates from the second position to the first position under the action of the second elastic member 24 to lift the accessory body 1 away from the accessory base 2 until the second plug-in member 22 moves to the first position. Fig.11 shown.

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

[0156] It should be noted that, in the process of the driving member 233 driving the second clamping member 231 to move from the clamping position to the unlocking position, the second clamping member 231 compresses the first elastic member 232. When the driving member 233 loses the external force, the second clamping member 231 returns to the clamping position under the action of the first elastic member 232, and in this process, the driving member 233 moves up along the second inclined surface. When the second plug-in member 22 rotates to the first position, the limiting portion 221 on the second plug-in member 22 abuts against the limiting surface 2111.
