[0048] 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 therein can be combined with each other in the absence of conflict.

[0049] 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.

[0050] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art:

[0051] By setting the height of the accessory body to be smaller than the outline diameter of the projection surface, the accessory body has a flat structure, which is convenient for wearing the accessory body, and the accessory body has at least one first light-emitting element, and the light of the first light-emitting element is emitted from the outer peripheral side of the accessory body, which is convenient for tracking and positioning the accessory body through the light of the first light-emitting element. Especially when the accessory body is worn at a position far away from the head-mounted device and fits to a certain part of the limb 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 and track the position of the accessory body, thereby improving the accuracy of positioning and improving the user experience.

[0052] The accessory body 1 and accessories disclosed herein can be used in various scenarios. In some embodiments, the accessory body 1 and accessories disclosed herein are used in extended reality (XR) scenarios. Extended reality refers to all real and virtual environments and human-computer interactions generated by computer technology and wearable devices, including virtual reality (VR), augmented reality (AR), and mixed reality (MR). In extended reality scenarios, the present disclosure can be used in conjunction with an extended reality headset.

[0053] As shown in Figures 1 to 2, 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.

[0054] 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 limb 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.

[0055] 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 based on the relevant algorithm, and then realize the tracking of the accessory body 1.

[0056] Furthermore, accessory body 1 is equipped with an IMU sensor. An IMU sensor is primarily 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 provide more accurate tracking using both optical and inertial measurement unit data.

[0057] For example, in a specific implementation, referring to Figure 1 , the accessory body 1 is a round pancake-shaped structure, and the height of the accessory body 1 is smaller than the diameter of the projection surface. This arrangement makes the accessory body 1 easy to wear and aesthetically pleasing.

[0058] As shown in FIG. 2 , in some embodiments, a first light concentrator 13 is provided 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.

[0059] It can be understood that the first light-emitting element 101 is arranged in the focusing cavity of the first focusing member 13. The focusing cavity can focus the light emitted by the first light-emitting element 101, thereby preventing the light spot formed by the first light-emitting element 101 from being too large and affecting the tracking and positioning, which is beneficial to improving the accuracy of tracking and positioning through the first light-emitting element 101.

[0060] For example, in a specific implementation, the first light concentrating member 13 may be selected to be foam with grooves.

[0061] In some embodiments, the accessory body 1 includes a main structure 11, wherein at least one first light-emitting element 101 is disposed on the top edge of the main structure 11, and the light emission direction is inclined toward the outer periphery of the accessory body 1 relative to the height direction of the accessory body 1. And / or, at least one first light-emitting element 101 is disposed on the outer periphery of the main structure 11.

[0062] 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 peripheral side 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 peripheral side of the main body structure 11; one is that at least one first light-emitting element 101 is set at the top edge of the main body structure 11, and at least one first light-emitting element 101 is set on the outer peripheral side of the main body structure 11.

[0063] 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.

[0064] For example, in one specific implementation, referring to FIG2 , a first light-emitting element 101 is provided at the top edge of the main body structure 11, and also at the outer periphery of the main body structure 11. This arrangement, staggering the first light-emitting elements 101 in the height direction of the main body structure 11, increases the probability of tracking light rays from the first light-emitting elements 101, thereby improving the accuracy of tracking and positioning the accessory body 1.

[0065] As shown in FIG. 1 and FIG. 2 , the accessory body 1 further includes a light-transmitting cover 12 , which covers the main body structure 11 .

[0066] It is understandable that by providing the transparent 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 .

[0067] 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 can also be visible light, or invisible light other than infrared light, such as near-infrared light. In this case, the light-transmitting cover 12 is configured accordingly based on the characteristics of the light emitted by the first light-emitting element 101.

[0068] In some embodiments, the first polygons formed by connecting any three adjacent first light-emitting elements 101 are different in shape. This facilitates identification of the accessory body 1 and determination of its position and posture based on the first polygons, especially when the accessory body 1 is used alone.

[0069] It should be noted that at least three adjacent first light-emitting elements 101 can be seen from any viewing angle along 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 along the circumference of the accessory body 1. Moreover, because the first polygons formed by any at least three adjacent first light-emitting elements 101 are different, this facilitates tracking and positioning of the accessory body 1, and allows the position of the accessory body 1 to be determined based on the first polygons.

[0070] The first light-emitting elements 101 are arranged in at least three adjacent shapes 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.

[0071] 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.

[0072] Understandably, when the accessory body 1 and the accessory base 2 are connected and used as a whole, the accessory base 2 may partially obstruct the first light-emitting elements 101. Therefore, the first polygons formed by the lines connecting any three adjacent first light-emitting elements 101 exposed at this time have different shapes. This still enables tracking and positioning of the accessory body 1, and the position of the accessory body 1 can be determined based on the first polygons.

[0073] For example, in a specific implementation, referring to FIG. 2 , eight first light-emitting elements 101 are provided on the main body structure 11 , and the shapes of triangles formed by connecting any three adjacent first light-emitting elements 101 are different.

[0074] 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, and 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 judged by identifying the shape of the triangle.

[0075] 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.

[0076] 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 element one 1011, light-emitting element two 1012, light-emitting element three 1013, light-emitting element four 1014 and light-emitting element five 1015 are arranged on the top edge of the main body structure 11, light-emitting element six 1016, light-emitting element seven 1017 and light-emitting element eight 1018 are arranged on the circumferential side of the main body structure 11, and light-emitting element six 1016 is located between light-emitting element one 1011 and light-emitting element two 1012, light-emitting element seven 1017 is located between light-emitting element one 1011 and light-emitting element five 1015, and light-emitting element eight 1018 is located between light-emitting element two 1012 and light-emitting element three 1013.

[0078] 4 , the length of the line between light-emitting element 1011 and light-emitting element 1016 is 12.03 mm, and the length of the line between light-emitting element 1016 and light-emitting element 2 is 14.81 mm. The angle formed by the line between light-emitting element 1011 and light-emitting element 1016 and the line between light-emitting element 1011 and light-emitting element 2 is 37.02°, the angle formed by the line between light-emitting element 1011 and light-emitting element 1016 and the line between light-emitting element 1016 and light-emitting element 2 is 113.71°, and the angle formed by the line between light-emitting element 1016 and light-emitting element 2 is 29.27°.

[0080] 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, the positions of the two triangles are different when viewed from the same perspective, and therefore the two triangles are not the same.

[0081] 6 , the length of the line between the second light-emitting element 1012 and the eighth light-emitting element 1018 is 12.30 mm, and the length of the line between the eighth light-emitting element 1018 and the third light-emitting element 1013 is 12.30 mm.

Of course, the arrangement of the eight first light-emitting elements 101 can be adjusted based on actual needs.

[0083] As shown in FIG. 7 and FIG. 8 , an embodiment of the present disclosure further provides an accessory, which includes the above-mentioned accessory body 1 and accessory base 2 .

[0084] 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 the at least one first light-emitting element 101 are connected to form a second polygon.

[0085] It can be understood that 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.

[0086] In some embodiments, the accessory base 2 has at least a first side and a second side, the first side and the second side being disposed opposite each other, and each side corresponding to at least one second light-emitting element 202. A 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 a 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.

[0087] That is, 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 identical size and shape. This allows the accessory to be tracked and positioned on both the first and second sides of the accessory base 2, regardless of how it is worn. This means that there are two orientations, and the user doesn't need to worry about the orientation of the accessory body 1 and / or base 2. Regardless of how the accessory body 1 and base 2 are installed, they will form two identical second polygons on the first and second sides, allowing the algorithm for tracking the accessory to remain the same.

[0088] 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. Using only one first light-emitting element 101 increases the distance between two adjacent second light-emitting elements 202 on the accessory base 2, making the shortest side of the second polygon greater than the longest side of any first polygon. This allows the second light-emitting elements 202 on the accessory base 2 and the first light-emitting element 101 on the accessory body 1 to work together to achieve long-range tracking and positioning of the accessory. The first light-emitting element 101 on the accessory body 1 can also be used to achieve short-range tracking and positioning, improving the problem of light spot adhesion during long-range tracking and positioning.

[0089] For example, in a specific implementation, referring to Figure 7, two 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 the same in size and shape.

[0090] 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 about a reference plane, and the two first light-emitting elements 101 participating in forming the second polygon are also symmetrically arranged about the above-mentioned reference plane, so that the two second polygons formed have the same size and shape.

[0091] 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.

[0092] 7 , in some embodiments, a second light concentrator 26 is provided on the accessory base 2 corresponding to each second light emitting element 202 , and the second light concentrator 26 has a light concentrating cavity for concentrating light.

[0093] 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 converge the light emitted by the second light-emitting element 202, avoiding 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.

[0094] For example, in a specific implementation, the second focusing member 26 may be selected to be foam with grooves.

[0095] 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 attached to a user's leg, waist, or arm. The accessory body 1 can also be used independently as a gaming peripheral for equipment such as a baseball bat or table tennis racket.

[0096] As shown in FIG8 and FIG9 , 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 .

[0097] 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.

[0098] Furthermore, the inner shell 212 is also a U-shaped structure. The inner shell 212 and the outer shell 211 are snap-fitted together to form the accessory base 2 , and the mounting cavity 201 is formed between the inner shell 212 and the outer shell 211 .

[0099] It should be noted that the second light emitting element 202 and the second light concentrating 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.

[0100] For example, in one specific implementation, if the second light-emitting element 202 is an infrared lamp, the inner housing 212 allows infrared light to pass through. Alternatively, the light emitted by the second light-emitting element 202 may be visible light or invisible light other than infrared light, such as near-infrared light. In this case, the inner housing 212 is configured accordingly based on the characteristics of the light emitted by the second light-emitting element 202.

[0101] In some embodiments, the accessory body 1 and the accessory base 2 are detachably connected, with at least a portion of the outer peripheral side of the accessory body 1 exposed. This facilitates the emission of light from the first light-emitting element 101 after the accessory base 2 and the accessory body 1 are connected, preventing the accessory base 2 from blocking the light emitted by the first light-emitting element 101.

[0102] 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.

[0103] As shown in Figures 8 to 11, 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 mounted on the base body 21 and can be plugged into and connected with the first plug connector 111. The clamping structure 23 can be engaged or disengaged with the first clamping member 121. When the first plug connector 111 and the second plug connector 22 are plugged into each other, the accessory body 1 is pressed, driving the second plug connector 22 to rotate so that the first clamping member 121 is engaged with the clamping structure 23.

[0104] It is understandable 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 engaged 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 and drives the second plug connector 22 to rotate so that the first clamping connector 121 is engaged 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. Moreover, the accessory body 1 and the accessory base 2 can be disassembled by disengaging the first clamping connector 121 and the clamping structure 23, and by disengaging the first plug connector 111 and the second plug connector 22, so that the accessory body 1 can be used alone, expanding the application scenarios.

[0105] In some embodiments, the first connector 111 and the second connector 22 are both electrical connectors, which are used to achieve signal transmission and / or electrical transmission between the accessory body 1 and the accessory base 2 .

[0106] The first connector 111 and the second connector 22 can be male-female connectors that can be electrically connected to each other, such as USB, Type-C, etc. Alternatively, the first connector 111 and the second connector 22 can be male-female connectors that can be electrically connected to each other, such as Anderson plugs.

[0107] For example, in a specific implementation, referring to Figures 9 and 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. When the first connector 111 and the second connector 22 are plugged together, not only does the plug-in connection between the accessory body 1 and the accessory base 2 occur, but also electrical and signal transmission between the accessory body 1 and the accessory base 2 is achieved. Alternatively, the first connector 111 may be a Type-C male connector, and the second connector 22 may be a Type-C female connector.

[0108] 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 can be electrically connected via the electrical connectors. This eliminates the need for additional wiring and simplifies the structure of the accessory body 1 and the accessory base 2.

[0109] Optionally, in other embodiments, connectors 25 are provided on both the accessory base 2 and the accessory body 1. 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.

[0110] 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.

[0111] For example, in a specific implementation, the first light-emitting element 101 or the second light-emitting element 202 can be electrically connected via the connector 25 to supply power to the first light-emitting element 101 and / or the second light-emitting element 202. Furthermore, in this case, the first connector 111 and the second connector 22 can cooperate to merely connect the accessory body 1 and the accessory base 2, without providing electrical or signal transmission functions. For example, if one of the first connector 111 and the second connector 22 is a plug-in post and the other is a plug-in hole, then only structural connection is achieved when the first connector 111 and the second connector 22 are connected. Alternatively, the first connector 111 and the second connector 22 can also provide electrical and / or signal transmission functions.

[0112] For example, in another specific implementation, the first light-emitting element 101 and / or the second light-emitting element 202 can be electrically transmitted 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.

[0113] It is understandable that when the first connector 111 and the second connector 22 are matched 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.

[0114] For example, in one specific implementation, referring to FIG9 , the connector 25 on the accessory body 1 is located on the bottom surface of the accessory body 1, i.e., the surface of the accessory body 1 that contacts the base body 21 when the first engaging member 121 engages the engaging structure 23. The connector 25 on the accessory base 2 is positioned to correspond to the position of the connector 25 on the accessory body 1. This allows the two connectors 25 to be connected when the accessory body 1 and the accessory base 2 are assembled, facilitating operation. Furthermore, the accessory body 1 and the accessory base 2 shield and protect the two connectors 25.

[0115] 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 .

[0116] In one 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 engaged, the power supply and the first light-emitting element 101 are electrically connected, and the power supply provides 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 engaged, the power supply and the second light-emitting element 202 are electrically connected, and the power supply provides 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, with the power supply on the accessory body 1 providing power to the first light-emitting element 101 and the power supply on the accessory base 2 providing power to the second light-emitting element 202.

[0117] It should be noted that one of the first engaging member 121 and the engaging structure 23 may be a engaging protrusion, and the other may be a engaging hole. When the accessory body 1 is pressed, the engaging protrusion may deform and insert into the engaging hole. Alternatively, both the first engaging member 121 and the engaging structure 23 may be engaging protrusions, and at least one of the two engaging protrusions may be elastically deformed to achieve engagement or disengagement.

[0118] As shown in 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 arranged on the base body 21. The second clamping member 231 has a clamping position that can be clamped with the first clamping member 121 and an unlocking position that is 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.

[0119] Understandably, the cooperation between the driving assembly and the second clamping member 231 can realize the clamping or disengagement of the second clamping member 231 and the first clamping member 121, thereby realizing that the accessory body 1 can be removed from the accessory base 2 and used separately.

[0120] 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 in a clamping position.

[0121] Understandably, in its natural state, the second clamping member 231 is in the engaged position, that is, when the accessory body 1 and the accessory base 2 are connected as one, the second clamping member 231 is in an engaged state with the first clamping member 121. By providing the first elastic member 232, a force can be applied to the second clamping member 231, ensuring a stable engagement between the first clamping member 121 and the second clamping member 231.

[0122] Furthermore, a guide arc surface is provided on the first clamping member 121 or the second clamping member 231 . When the accessory body 1 is pressed, the accessory body 1 can pass over the second clamping member 231 through the guide arc surface and be clamped to the second clamping member 231 .

[0123] In other words, by providing the 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 clamping member 231. Furthermore, as the accessory body 1 slides along the guide arc surface, the second clamping member 231 compresses the first elastic member 232. Thus, after the accessory body 1 passes over the guide arc surface, the force exerted by the first elastic member 232 to restore its original shape pushes the second clamping member 231 against the first clamping member 121, achieving the clamping connection between the first clamping member 121 and the second clamping member 231. Therefore, after the accessory body 1 and the accessory base 2 are connected via the first plug-in connector 111 and the second plug-in connector 22, the clamping connection between the accessory body 1 and the accessory base 2 can be achieved simply by pressing the accessory body 1 to allow the first elastic member 232 to move, without requiring any additional operation.

[0124] For example, in a specific implementation, referring to Figures 10 and 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.

[0125] For example, in a specific implementation, referring to Figures 8, 10, and 11, the first engaging member 121 is a locking hole. When the first engaging member 121 is engaged with the second engaging member 231, the second engaging member 231 extends into the locking hole. Alternatively, the first engaging member 121 may be a protrusion provided on the accessory body 1.

[0126] In addition, it should be noted that the above-mentioned latching hole is provided on the light-transmitting cover 12 .

[0127] 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.

[0128] That is, when the first clamping member 121 and the second clamping member 231 are engaged, the second clamping member 231 is in the engaged 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 surface to drive the second clamping member 231 from the engaged position to the unlocked position, thereby compressing 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. After the driving member 233 loses the external force, the force of the first elastic member 232 to restore its original state drives the second clamping member 231 from the unlocked position to the engaged position. During this process, the driving member 233 moves upward along the second inclined surface.

[0129] It should be noted that in order to improve the clamping effect of the first clamping member 121 and the second clamping member 231, the first elastic member 232 can be set to be in a compressed state when the second clamping member 231 is in the clamping position. In this way, the elastic force of the first elastic member 232 can be used to enhance the force between the second clamping member 231 and the first clamping member 121, thereby improving the clamping stability.

[0130] Further, as shown in Figures 10 and 11, 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 of the 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.

[0131] 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 so that the driving member 233 moves downward along the second inclined surface can drive 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.

[0132] As shown in Figures 10 and 11, in some embodiments, the base body 21 has an accommodating cavity 2121 capable of accommodating the accessory body 1. A portion of the second plug connector 22 is located within the accommodating cavity 2121. When the second clamping member 231 is in the engaged position, a portion of the second clamping member 231 is located within the accommodating cavity 2121. The provision of the accommodating cavity 2121 can provide protection for the accessory body 1 and can reduce the overall thickness of the accessory to a certain extent, thereby facilitating a miniaturized design of the accessory.

[0133] 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.

[0134] For example, in one specific implementation, the depth of the accommodating 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 be exposed above the accessory base 2, facilitating tracking of the light-emitting portion within the accessory body 1 and making it easier to grasp the accessory body 1 when removing the accessory body 1 and the accessory base 2. Furthermore, the top of the accessory body 1 exposed above the accessory base 2 facilitates cleaning of the accessory body 1. Alternatively, the depth of the accommodating cavity 2121 can be set to equal the height of the accessory body 1, thereby fully enclosing the sides of the accessory body 1 and providing enhanced protection.

[0135] 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 the height of the accessory body 1 .

[0136] 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.

[0137] As shown in FIG8 , FIG10 and FIG11 , the inner shell 212 of the base body 21 has the aforementioned accommodating cavity 2121 , and the inner shell 212 is provided with a first through hole for the second connector 22 to pass through and a second through hole for the second clamping member 231 to pass through.

[0138] 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 aforementioned accommodating cavity 2121. In addition, the aforementioned mounting cavity 201 is formed between the outer shell 211 and the inner shell 212, thereby providing a mounting space for the snap-fit ​​structure 23.

[0139] 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 the inner shell 212 has a hole for the connector 25 on the accessory body 1 to pass through, or the connector 25 on the accessory base 2 to extend into the accommodating cavity 2121. This prevents the two connectors 25 from being exposed after the accessory body 1 and the accessory base 2 are assembled, which not only improves appearance but also protects the connectors 25.

[0140] As shown in Figures 9 to 11, in some embodiments, the accessory base 2 further includes a second elastic member 24, which deforms and provides a lifting force for the second connector 22 to rotate to lift the accessory body 1 away from the accessory base 2.

[0141] 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.

[0142] Furthermore, the second connector 22 is rotatably connected to the base body 21 via a rotating shaft.

[0143] For example, in a specific implementation, the second elastic member 24 is selected to be a torsion spring, which is sleeved on the rotating shaft, and the two free ends of the torsion spring are respectively connected to or abut 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 and the second plug-in connector 22 rotates, the second elastic member 24 undergoes elastic deformation. When the first clamping member 121 and the second clamping member 231 are disengaged, the force of the second elastic member 24 to restore its original state drives the second plug-in connector 22 to rotate in the opposite direction, lifting the accessory body 1 away from the accessory base 2.

[0144] For example, in another specific implementation, the second elastic member 24 can also be 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 returning to its original state causes the second plug-in connector 22 to rotate and lift the accessory body 1.

[0145] 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 in the first position. When the second latching member 231 is disengaged 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 in the first position and plugged into the first connector 111, pressing the accessory body 1 toward the accessory base 2 causes the second connector 22 to rotate, causing the second latching member 231 to engage with the first latching member 121. At this point, the second connector 22 is in the second position, and the second elastic member 24 deforms, generating a force that drives the second connector 22 from the second position to the first position.

[0146] Specifically, referring to Figure 10 , when the second clamping member 231 is clamped to the first clamping member 121, that is, when the second clamping member 231 is in the clamping position, the second plug-in connector 22 is in the second position. At this time, the second plug-in connector 22 forms a first preset angle with the bottom surface of the accommodating cavity 2121. Referring to Figure 11 , when the second plug-in connector 22 is in the first position, the second plug-in connector 22 forms a second preset angle with the bottom surface of the accommodating cavity 2121, and the second preset angle is greater than the first preset angle.

[0147] 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 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 easier for the first connector 111 on the accessory body 1 to connect or disconnect with the second connector 22.

[0148] Further, referring 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 .

[0149] 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 in the first position, the limiting portion 221 and the limiting surface 2111 abut against each other. That is, the limiting surface 2111 and the limiting portion 221 cooperate to allow the second connector 22 to rotate to the first position under the action of the second elastic member 24 and then stop rotating.

[0150] It should be noted that the limiting surface 2111 is provided on the housing 211 and is located on the inner side of the housing 211 .

[0151] In summary, the specific disassembly and assembly process of this accessory is described in detail:

[0152] 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 in the first position, the second clamping member 231 is located in the clamping position, and the limiting portion 221 on the second connector 22 abuts against the limiting surface 2111.

[0153] 1. When installing the accessory body 1, first connect the second connector 22 to the first connector 111. At this point, the second connector 22 is in the first position and supports the accessory body 1, as shown in Figure 11. Then, press the accessory body 1 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. Continue pressing the accessory body 1 until the accessory body 1 passes over the guide arc surface and the second clamping member 231 engages with the first clamping member 121. At this point, the second connector 22 is in the second position, and the second clamping member 231 is in the clamping position, completing the installation of the accessory body 1, as shown in Figure 10.

[0154] It should be noted that as the accessory body 1 slides along the guide arc, the second clip 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, the first elastic member 232 pushes the second clip 231 toward the inside of the accommodating cavity 2121, causing the second clip 231 to abut against the first clip 121. Furthermore, as the accessory body 1 is pressed to rotate the second connector 22, the second elastic member 24 deforms and generates a force that drives the second connector 22 from the second position to the first position.

[0155] 2. To remove the accessory body 1, press the driver 233, causing it to move downward along the second inclined surface, driving the second latch 231 from the engaged position to the unlocked position. After the second latch 231 and the first latch 121 are disengaged, the second connector 22, under the action of the second elastic member 24, rotates from the second position to the first position, lifting the accessory body 1 away from the accessory base 2, until the second connector 22 moves to the first position, as shown in Figure 11.

[0156] 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.

[0157] It should be noted that when the driver 233 drives the second engaging member 231 from the engaged position to the unlocked position, the second engaging member 231 compresses the first elastic member 232. When the driver 233 loses the external force, the second engaging member 231 returns to the engaged position under the action of the first elastic member 232. During this process, the driver 233 moves upward along the second inclined surface. When the second connector 22 rotates to the first position, the stopper 221 on the second connector 22 abuts the stopper surface 2111.
