[0067] Combine the following Figures 1 to 21 A camera module 100 and an intelligent electronic device according to an embodiment of the present application are described.

[0068] like Figures 1 to 10 As shown, according to some embodiments of the present application, a camera module 100 is provided, which is applied to a head-mounted device 200, including: a bracket assembly and a camera assembly, the bracket assembly includes a first bracket 1 and a second bracket 2, the first bracket 1 is movably connected to the second bracket 2, the second bracket 2 can be movably connected to the head-mounted device 200, so that the second bracket 2 has at least two degrees of freedom in two directions relative to the head-mounted device 200; the camera assembly includes a camera 6, the camera 6 is fixed to the first bracket 1, and is used to obtain image information, and the camera assembly can transmit the image information to the head-mounted device 200.

[0069] Specifically, in this embodiment, the provided camera module 100 can be applied to the head mounted device 200 to obtain image information. Among them, the camera 6 can be used to capture image information such as facial features of the user 300, and can transmit the captured information to the head mounted device 200. The head mounted device 200 can judge the facial expression of the user 300 based on the image information, so that the head mounted device 200 can better serve the user 300 in scenes such as meetings and virtual games. Of course, the camera 6 can also obtain image information of other positions of the user 300, or obtain environmental information of the user 300, etc., which is selected according to actual needs, and this application does not limit this.

[0070] In practical applications, the present application fixes a camera 6 for capturing image information on a first bracket 1, and enables the bracket to be movably connected to a second bracket 2, and the second bracket 2 can be movably connected to a head-mounted device 200, so that the camera 6 can achieve freedom of movement in at least one direction relative to the head-mounted device 200 through the movement of the first bracket 1 relative to the second bracket 2, and the camera 6 can also achieve freedom of movement in another direction through the movement of the second bracket 2 relative to the head-mounted device 200, thereby improving the angle adjustment range of the camera 6.

[0071] like Fig. 9 As shown, the funnel shape in the figure is a schematic diagram of the capture range of the camera 6. It can be seen that the shooting angle of the camera 6 is widened by rotating the first bracket 1 relative to the second bracket 2, thereby achieving different needs of different groups of people, such as recognition and acquisition of facial information of different groups of people, and achieving the best capture effect, so that the head-mounted device 200 can meet the needs of different users 300. Among them, the information transmission between the camera 6 and the head-mounted device 200 can be transmitted by wired means such as wires or flexible circuit boards, or by wireless means such as Bluetooth modules and NFC, and this application does not limit this.

[0072] In the above embodiment, the first bracket 1 and the second bracket 2, on the one hand, can serve as supporting structures to fix and carry the entire camera assembly, and on the other hand, can realize independent activities of the camera 6 fixed on the first bracket 1, such as rotation or movement, through a movable connection, which not only ensures the stability of the entire camera module 100 when applied to the head-mounted device 200, but also ensures the adjustability of the capture range of the camera 6, improves the accuracy of the camera 6 in acquiring image information, and at the same time reduces the overall volume of the camera 6 module to avoid affecting the function of the head-mounted device 200 itself.

[0073] Among them, the first bracket 1 and the second bracket 2 can be connected by movable parts such as a connecting shaft, a movable guide rail assembly, and a magnetic suction assembly, and the second bracket 2 and the head-mounted device 200 can also be connected by the above-mentioned movable parts. The matching design is specifically performed according to the adjustment requirements of the camera 6 or the requirements of the head-mounted device 200, and the present application does not impose any restrictions on this.

[0074] The above-mentioned camera module 100 provided in the present application has a simple structure, a small size, and is easy to install. Through the adjustment of its internal connection relationship and the connection relationship with the external smart products such as the head-mounted device 200, it can adapt to different user 300 needs and achieve the optimal facial information capture effect of the camera 6 by widening the shooting angle of the camera 6 when acquiring information, such as capturing the facial information of the user 300, thereby improving the user 300 experience and being suitable for mass production.

[0075] Alternatively, if Fig. 9 , Fig.16 , Fig.17 and Fig.18 As shown, the bracket assembly also includes a first connecting member and a second connecting member 5; the second bracket 2 can be connected to the head-mounted device 200 through the second connecting member 5, and the second connecting member 5 extends along the first direction (X direction in the figure), so that the second bracket 2 can move along the first direction relative to the head-mounted device 200, and can rotate around the first direction; the first bracket 1 is connected to the second bracket 2 through the first connecting member, so that the first bracket 1 can rotate around the second direction relative to the second bracket 2, and the extension direction of the first connecting member is the second direction (Y direction in the figure); wherein the lens direction of the camera 6 (Z direction in the figure) is perpendicular to the second direction, and the second direction is perpendicular to the first direction. wherein, rotating around the first direction or the second direction refers to rotating with the first direction or the second direction as the rotation axis.

[0076] Specifically, in this embodiment, by limiting the movable direction of the second bracket 2 relative to the head-mounted device 200, and limiting the movable direction of the first bracket 1 relative to the second bracket 2, the camera module 100 can have three degrees of freedom of movement in three directions when applied to the head-mounted device 200. The lens orientation of the camera 6 determines the image quality of the image captured by the camera 6. The angle adjustment of the camera 6 in three different directions makes the image quality obtained clearer and more accurate. Among them, the movable connecting parts on the first bracket 1 and the second bracket 2 can be movably connected by a rotating shaft to achieve rotation or movement in different directions.

[0077] For example, in one embodiment, the camera module 100 is applied to smart glasses. The camera module 100 can be movably assembled at the bottom of the frame 8 of the smart glasses, and is movably connected to the frame 8 and the first bracket 1 respectively through the second bracket 2, so that the camera 6 can rotate around the second direction with the first bracket 1 relative to the second bracket 2, or rotate around the first direction or move along the first direction with the second bracket 2 relative to the smart glasses, so that the camera 6 can swing in the front-to-back direction (when the user 300 wears it, the direction of the user 300 is used as the basis), move left-right, or swing up and down relative to the smart glasses to adjust the distance between the camera 6 and the face of the user 300, or the distance between the camera 6 and various parts of the facial features of the user 300, etc., refer to Fig. 9 , Fig.15 and Fig.21 .

[0078] In the above embodiment, if the camera 6 needs to obtain the facial information of the user 300, the lens of the camera 6 needs to be oriented roughly toward the face of the user 300. When designing the first bracket 1 and the second bracket 2, the camera 6 can be placed at a certain distance from the face of the user 300 to avoid the camera 6 being too close to the face of the user 300, resulting in unclear images, or causing interference between the camera 6 and the face of the user 300, thereby further improving the user experience. In actual applications, the first direction is set to the left and right direction of the user 300, so that the camera module 100 can obtain the most suitable camera 6 angle and the best image quality effect with fewer activity plans.

[0079] In one embodiment, the first bracket 1 and the second bracket 2 are connected to each other by a first connecting member, and the camera 6 is fixed to the first bracket 1, so that the camera 6 can rotate around the first connecting member as a rotation axis along with the first bracket 1 relative to the second bracket 2; the second bracket 2 can be movably connected to the head-mounted device 200 through the second connecting member 5, so that the camera 6 can also move along the first direction and rotate around the first direction. Fig.10 As shown, this connection method is simple and reliable, simplifies the assembly relationship of the bracket assembly, and reduces the connection cost. In addition, the lens of the camera 6 is perpendicular to the second direction, so that when the camera 6 rotates around the second direction, it will not interfere with other structural parts.

[0080] like Fig. 9As shown, Figure b is a schematic diagram of the relative position relationship between the camera 6 and the first bracket 1 and the second bracket 2 at the initial position. The lens of the camera 6 faces upward, and it can rotate counterclockwise or clockwise around the second direction with the first bracket 1, which not only realizes the adjustment of the angle of the camera 6, but also avoids the interference or restriction of the camera 6 by the first bracket 1 or the second bracket 2 during the rotation process, which is convenient for the user 300 to operate. Among them, Figure a shows the position of the camera 6 after rotating a certain angle counterclockwise around the second direction with the first bracket 1. It can be seen that the capture range of the camera 6 is significantly expanded to the left range; Figure c shows the camera 6 rotates a certain angle clockwise around the second direction with the first bracket 1. It can be seen that the capture range of the camera 6 is significantly expanded to the right range.

[0081] Fig. 9 The funnel-shaped shape at the lens of each camera 6 illustrates the approximate capture range of the camera 6. When the camera module 100 is mounted on the head-mounted device 200, if the second direction is the front-back direction, it can be clearly seen that it expands the acquisition of facial information of the camera 6 at the left and right positions of the user 300. Among them, the counterclockwise or clockwise rotation range or angle of the first bracket 1 around the second direction can be adjusted according to actual needs, and this application does not limit this.

[0082] Alternatively, if Figure 2 , Figure 3 and Figure 8 As shown, the first connecting member includes a first magnetic body 3 and a second magnetic body 4. The first magnetic body 3 and the second magnetic body 4 are respectively assembled on the first bracket 1 and the second bracket 2. The first bracket 1 and the second bracket 2 are adsorbed and connected by the first magnetic body 3 and the second magnetic body 4.

[0083] Specifically, in this embodiment, the first connecting member is two magnetic bodies, and the two magnetic bodies are respectively assembled on the mating surfaces of the first bracket 1 and the second bracket 2. In practical applications, the first bracket 1 and the second bracket 2 can be adsorbed together by the first magnetic body 3 and the second magnetic body 4, and the connection relationship between the first bracket 1 and the second bracket 2 is realized, and the requirement that the first bracket can rotate relative to the second bracket 2 around the second direction is met, and the adsorption and separation of the magnetic bodies are simple and easy to operate, and the cost is low.

[0084] In the above embodiment, a groove can be provided on the mating surface of the first bracket 1 and the second bracket 2, so that the first magnetic body 3 and the second magnetic body 4 are embedded and fixed in the groove, and the first magnetic body 3 and the second magnetic body 4 can be designed to be cylindrical, which is convenient for positioning, assembly and rotation. In addition, the magnetic connection makes the first bracket 1 and the second bracket 2 detachable, which is convenient for subsequent replacement and repair of parts.

[0085] Alternatively, if Figures 6 to 9As shown, a first limiting groove 11 and a limiting rib 21 are respectively provided on the mating surfaces of the first bracket 1 and the second bracket 2; the limiting rib 21 is located in the first limiting groove 11, and the first limiting groove 11 can limit the rotation angle of the first bracket 1 relative to the second bracket 2 in the second direction.

[0086] Specifically, in this embodiment, a first limiting groove 11 and a limiting rib 21 are respectively provided on the first bracket 1 and the second bracket 2, so that when the first bracket 1 and the second bracket 2 are movably connected together through a connecting piece, the limiting rib 21 can be located in the first limiting groove 11. Through the restrictions of the shape and angle of the first limiting groove 11, the first bracket 1 can be limited within a set angle range when rotating relative to the second bracket 2 around the second direction to meet specific functional requirements.

[0087] like Figure 8 As shown, a first limiting groove 11 is provided on the first bracket 1, and a limiting rib 21 matching the first limiting groove 11 is provided on the docking surface of the second bracket 2. The first limiting groove 11 is distributed on both sides of the first connecting member, and the limiting rib 21 is also distributed on both sides of the first connecting member, so that during the rotation process, the rotation angle and rotation range of both sides are roughly equivalent, which is convenient for the angle adjustment of the first bracket 1. In practical applications, the first bracket 1 can be rotated 20° to 30° relative to the second bracket 2, which can basically meet the use requirements of different users 300. In addition, the first limiting groove 11 and the limiting rib 21 are respectively provided on one of the first bracket 1 and the second bracket 2, that is, the first limiting groove 11 is provided on the first bracket 1, and the limiting rib 21 is provided on the second bracket 2. If the first limiting groove 11 is provided on the second bracket 2, the limiting rib 21 is provided on the first bracket 1, and the present application does not limit this.

[0088] Alternatively, if Figures 6 to 8 As shown, the first limiting groove 11 includes a plurality of limiting portions, which are radially arranged with the first connecting member as the center; the limiting rib 21 is located in one of the limiting portions, and can be moved to another limiting portion under the action of external force to adjust the rotation angle of the first bracket 1 relative to the second bracket 2 in the second direction.

[0089] Specifically, in actual applications, the first limiting groove 11 is set to a plurality of limiting portions arranged radially with the first connecting member, and each limiting portion is symmetrically distributed relative to the first connecting member, so that the two parts of the reinforcing rib are respectively located in a limiting portion on one side, so that the first bracket 1 can be limited to a fixed position relative to the second bracket 2.

[0090] like Figure 6As shown, three limiting parts are respectively provided on both sides of the first connecting member, and one limiting rib 21 is respectively provided on both sides of the first connecting member. In the initial state of the camera 6, the two limiting ribs 21 can be respectively located at the limiting part II 112 and the limiting part opposite to the limiting part II 112. At this time, the positional relationship between the first bracket 1, the camera 6 and the second bracket 2 is as shown in FIG. Fig. 9 b in the figure. When the first bracket 1 needs to be rotated clockwise, the two reinforcing ribs can be located at the limiting portion III 113 and the limiting portion diagonally opposite to the limiting portion III 113, respectively. At this time, the position between the first bracket 1, the second bracket 2 and the camera 6 is referenced Fig. 9 When the first bracket 1 needs to be rotated counterclockwise, the two reinforcing ribs can be located at the limiting portion Ⅰ111 and the limiting portion diagonally opposite to the limiting portion Ⅰ111. At this time, the position reference between the first bracket 1, the second bracket 2 and the camera 6 is Fig. 9 a in.

[0091] It can be seen that, in this embodiment, by designing the shape and position of the first limiting groove 11, the first bracket 1 can be rotated and fixed at a certain angle relative to the second bracket 2 to meet the position requirements of the camera 6. Among them, when the first connecting member adopts the first magnetic member and the second magnetic member, if the first bracket 1 needs to be rotated, the first bracket 1 can be first moved in the second direction away from the second bracket 2, and then rotated to a suitable position, and then the first bracket 1 is released to be adsorbed on the second bracket 2, so that the angle of the camera 6 is simple and easy to operate.

[0092] Alternatively, if Fig.14 and Fig.16 As shown, in the first direction, the width of the second bracket 2 is smaller than the length of the second connecting member 5 , so that the second bracket 2 can move relative to the second connecting member 5 in the first direction.

[0093] Specifically, in this embodiment, the width of the second bracket 2 is smaller than the length of the second connecting member 5, so that the second bracket 2 can move along the first direction relative to the second connecting member 5, thereby realizing the freedom of the camera 6 in the first direction. Fig.15 and Fig.16 As shown, when the second bracket 2 is movably connected to the smart glasses through the second connecting member 5, there is a certain gap between the two sides of the second bracket 2 and the smart glasses. When the second bracket 2 moves along the first direction relative to the second connecting member 5, the sizes of the gaps d and e on both sides will increase or decrease, so that the camera 6 has different positions relative to the head-mounted device 200 in the first direction.

[0094] In the above embodiment, the second bracket 2 and the second connecting member 5 can be fastened together so that the second bracket 2 can stop at a suitable position when moving along the first direction or rotating around the first direction. For example, an elastic member is clamped in the contact area between the second bracket 2 and the second connecting member 5, which can meet the needs of rotation or movement and the purpose of hovering. When the smart glasses are worn on the head of the user 300, the movement of the camera 6 in the first direction is the movement in the left and right directions relative to the user 300, and the rotation around the first direction is the swing close to or away from the face of the user 300, which realizes the accurate acquisition of facial information of different areas of the face of different users 300.

[0095] Alternatively, if Fig.14 and Fig.16 As shown, the second connecting member 5 is a spring ear.

[0096] Specifically, in practical applications, the second connecting member 5 is a spring ear, which can facilitate the assembly and connection of the camera module 100 and the head-mounted device 200, and is also convenient for disassembly at any time, thereby improving the usability of the camera module 100. Among them, the spring ear is a connecting member commonly used in the watch industry to connect the watch strap and the watch body, and the two ends can be controllably extended and retracted under the action of external force, and the cost is relatively low.

[0097] Optionally, the first bracket 1 is detachably and movably connected to the second bracket 2; and / or, the second bracket 2 can be detachably and movably connected to the head-mounted device 200.

[0098] In actual applications, the first bracket 1 and the second bracket 2 are designed to be detachably connected, and the second bracket 2 and the head-mounted device 200 are designed to be detachably connected. On the one hand, it is convenient for the user 300 to store and use, and on the other hand, it is also convenient for disassembly and maintenance, thereby reducing the cost of replacing parts.

The present application uses FPC 7 to connect the camera 6 and the head-mounted device 200. On the one hand, it can ensure the reliability of information transmission between the two. On the other hand, FPC 7 is relatively soft. When the first bracket 1 moves relative to the second bracket 2, it can achieve a certain degree of bending or twisting and other deformations to adjust the position of the camera 6. In addition, FPC 7 is connected to the head-mounted device 200 along the second bracket 2, which improves the neatness of the camera module 100 and prevents it from interfering with other devices or users 300 during activities.

[0103] Alternatively, if Figures 1 to 5 As shown, the first bracket 1 is provided with a first groove 12 , and the camera 6 is fixed in the first groove 12 ; the second bracket 2 is provided with a second groove 22 , and at least a part of the FPC 7 is fixed in the second groove 22 .

[0104] Specifically, in this embodiment, the first groove 12 provided on the first bracket 1 is used to fix the camera 6, and the second groove 22 on the second bracket 2 is used to fix the FPC 7, which further improves the connection reliability and integrity of the camera assembly and the bracket assembly, and also facilitates the positioning of the two components during the assembly process. In practical applications, the camera 6 and the FPC 7 can be bonded and fixed in the first groove 12 and the second groove 22, respectively. The depth and shape of the first groove 12 and the second groove 22 can be adaptively adjusted according to the specific structures of the camera 6 and the FPC 7, respectively.

[0105] Second, as Figures 10 to 21As shown, according to an embodiment of the present application, a smart electronic device is provided, comprising: a head-mounted device 200 and a camera module 100 of the first aspect; the camera module 100 is movably connected to the head-mounted device 200 through a bracket assembly, so that the camera module 100 can move along a first direction relative to the head-mounted device 200, and can rotate around the first direction; wherein the first direction is the left and right direction of the user 300.

[0108] Specifically, in the present embodiment, the camera module 100 and the head mounted device 200 are two different components. When the camera module 100 is movably connected to the head mounted device 200, it protrudes from the head mounted device 200 instead of being mounted inside or on the inner side of the head mounted device 200. This ensures the breadth and diversity of the camera module 100 in acquiring image information on the one hand, and can also be separated from the head mounted device 200 to adapt to other possible smart devices on the other hand, thereby improving the wide application of the camera module 100.

[0109] In some embodiments, the head-mounted device 200 generally has a main body and a wearing part, the main body is generally used to realize the functions of the head-mounted device 200, and the wearing part is generally used to fix the main body on the head of the user 300.

[0111] Specifically, in the present embodiment, the second limiting groove 81 is provided to protect the second connecting member 5 and improve the reliability of the connection between the camera module 100 and the head-mounted device 200. On the other hand, the shape of the second limiting groove 81 is designed to limit the rotation angle of the second bracket 2 when rotating around the first direction to meet the angle adjustment requirements of the camera 6. At the same time, it also avoids the camera module 100 from colliding with the face of the user 300 when the angle is rotated too much during actual use. Fig.17 As shown, the second limiting groove 81 can limit the camera module 100 from swinging between positions f to h.

[0113] Specifically, in this embodiment, the elastic protrusion 82 in the second limiting groove 81 can be adapted to the third limiting groove 23 provided on the second bracket 2. When it is necessary to adjust the swing angle of the camera 6 around the first direction, the elastic protrusion 82 is located in any third limiting groove 23, so that the camera module 100 can be fixed at a specific position. When it is necessary to adjust the angle of the camera 6, it only needs to be pushed by a force greater than the friction force between the two. When the external force is stopped, the bracket assembly can stay in the current position.

[0114] like Fig.18 As shown, the second end of the second bracket 2 is provided with three third limiting grooves 23 extending along the first direction. The initial position of the second bracket 2 can be set to the position of the third limiting groove 23 in the middle where the elastic protrusion is located in FIG. When the camera 6 needs to be moved to the position on the left side of the figure, the second bracket 2 is pushed to rotate toward the left side until the elastic protrusion 82 is located in the third limiting groove 23 on the far left. Fig.18In the figure i, when the camera 6 needs to be moved to the right side of the figure, the second bracket 2 is pushed to rotate to the right until the elastic protrusion 82 is located in the third limiting groove 23 on the far right, refer to Fig.18 The k-graph in .

[0115] The structure adopted in this embodiment allows the user 300 to simply push the camera module 100 to adjust the position of the camera 6 during the process of adjusting the camera module 100. The operation is relatively simple, the structure is simple, and the cost is low.
