[0052] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0057] Head-mounted devices, that is, devices worn on the user's head for use, include VR devices (virtual reality devices) and AR devices (augmented reality devices). In the process of continuous updating of head-mounted devices, it is found that more head-mounted devices need to be provided with cameras on the outer surface to shoot the outside of the head-mounted devices. However, there is a disadvantage in the use of head-mounted devices at this time. That is, since the camera is exposed at this time, the camera on the head-mounted device may be hit by a collision or hit by the ground when the device falls during the use of the head-mounted device, thereby causing damage to the camera. In other words, this type of head-mounted device has poor protection for the exposed camera. In the current industry, there are also some measures to protect the exposed camera on the head-mounted device, such as: adding an enclosure plate to the periphery of the camera to protect the camera through the enclosure plate. At this time, although the protective effect of the camera can be improved, the shooting angle of the camera will be blocked by the enclosure plate at the periphery, which affects the shooting angle of the camera and affects the subsequent shooting effect.

[0058] Therefore, based on the above considerations, on the basis of ensuring that the camera has a good shooting angle, in order to improve the protection of the camera, this application proposes a new camera module. The camera module innovatively sets the camera to be driven by a driving mechanism to have an extended and retracted state, and then when the head-mounted device does not need to use the camera, the camera can be retracted into the shell of the head-mounted device to protect the camera through the shell of the head-mounted device. When the head-mounted device needs to use the camera, the camera can be extended from the exposure hole on the shell of the head-mounted device to achieve the extension of the camera and have a larger shooting angle.

[0059] Next, the specific structure of the camera module proposed in this application is explained in a specific embodiment. In one embodiment of this application, please refer to Figures 1 to 4The camera 15 module proposed in the present application is applied to a head mounted device 100, the head mounted device 100 comprises a shell 30, the shell 30 is provided with an exposure hole 31 connecting the inside and the outside thereof, the camera 15 module comprises a carrier 11, a driving mechanism 13 and a camera 15; the carrier 11 is used to be arranged in the shell 30; the driving mechanism 13 is arranged on the carrier 11; the camera 15 is connected to the driving mechanism 13, and the driving mechanism 13 can drive the camera 15 to slide so that the camera 15 extends out and retracts from the exposure hole 31.

[0060] As described above, the head mounted device 100 can be a VR device, and of course, it can also be an AR device, as long as it is worn on the user's head. The head mounted device 100 includes a shell 30, and the shell 30 can be used to install the main part of the head mounted device 100. For example: when the head mounted device 100 is a VR device or an AR device, the shell 30 is used to install a display body for displaying a virtual display screen or an augmented reality screen. The exposure hole 31 on the shell 30 can be used for the camera 15 to extend and retract, so the exposure hole 31 can be adaptively set according to the number of cameras 15 that need to be exposed by the head mounted device 100, ensuring that one exposure hole 31 corresponds to one camera 15.

[0061] The carrier 11 can be used to be arranged on the inner side of the shell 30 of the head-mounted device 100, and provide an installation position to install the bearing drive mechanism 13, etc. Among them, the carrier 11 can form an integral structure with the shell 30 in the head-mounted device 100. Of course, the carrier 11 can also be arranged in a separate structure with the shell 30 in the head-mounted device 100, so that the drive mechanism 13 and other components in the camera 15 module can be first installed on the carrier 11 with a relatively small volume and a relatively simple structure, and then the camera 15 module that is also combined to form a whole can be installed on the shell 30 of the head-mounted device 100 at one time to improve the convenience of its installation on the shell 30 of the head-mounted device 100. In addition, the carrier 11 can be any structural form such as a block, a plate or a column.

[0062] The driving mechanism 13 can be used to provide a driving force to drive the camera 15 to slide, so that the camera 15 can be extended from the exposure hole 31 when shooting is required. Figure 1 As shown; when there is no need to shoot, it can be retracted from the exposure hole 31. The drive mechanism 13 can be a combination of a rotating drive member 131 and a transmission assembly 132 as described below. Of course, the drive mechanism 13 can also only include linear drive members such as linear cylinders or linear motors. The present application does not limit the specific structural type of the drive mechanism 13, and it is sufficient to ensure that it can be used to provide a driving force to drive the camera 15 to slide.

[0063] The camera 15 can be used for shooting. The number of the camera 15 can be one, or at least two. At this time, the at least two cameras 15 can be driven separately by at least two driving mechanisms 13, or synchronously by one driving mechanism 13. In addition, when the camera 15 is extended by the driving mechanism 13, only the end of the camera 15 used for shooting can be extended from the exposure hole 31, or the entire camera 15 can be extended from the exposure hole 31. Similarly, when the camera 15 is driven to retract by the driving mechanism 13, the camera 15 can be completely retracted into the shell 30, or part of the camera 15 can be retracted into the shell 30, and the other part can be retracted into the exposure hole 31.

[0064] When the camera 15 module in the technical solution of the present application is applied to the head mounted device 100, the driving mechanism 13 arranged on the carrier 11 can drive the camera 15 to slide, so that the camera 15 can be extended and retracted from the exposure hole 31 on the shell 30 of the head mounted device 100. Therefore, when the head mounted device 100 needs to use the camera 15, the camera 15 can be driven to extend so that the camera 15 can normally shoot the outside of the head mounted device 100. When the head mounted device 100 does not need to use the camera 15, the camera 15 can be driven to retract so that the shell 30 of the head mounted device 100 can be used to store and protect it. At this time, the possibility of the camera 15 being damaged by collision with foreign objects or the ground can be reduced, which is conducive to improving the protection of the camera 15. Moreover, since the camera 15 is protected by retraction, it can be extended from the exposure hole 31 when it needs to work, so that the protective structure formed by the head mounted device 100 for the camera 15 will not block the shooting angle of the camera 15 when it is working. That is, the camera 15 has a larger shooting angle of view because it is exposed when working, which is beneficial to improving the shooting effect of the camera 15 when working.

[0065] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the driving mechanism 13 includes a rotating driving member 131 and a transmission assembly 132, and the rotation axis of the rotating driving member 131 and the sliding direction of the camera 15 are arranged to intersect; the transmission assembly 132 is connected to the rotating driving member 131 and the camera 15, so that the rotating driving member 131 drives the camera 15 to slide through the transmission assembly 132.

[0066] The rotary drive member 131 can be used to provide a rotary driving force, which can be a motor, or of course a rotary cylinder. This application does not limit this, and it is sufficient to ensure that it can be used to provide a rotary driving force. In addition, the rotary drive member 131 can be detachably connected to the carrier 11, so that the rotary drive member 131 can be disassembled, repaired or replaced when damaged, thereby improving the convenience of repairing or replacing the rotary drive member 131. At this time, the rotary drive member 131 can be connected by screws, or snap connections, or magnetic connections, etc., to simplify the disassembly and assembly process and improve the convenience of its disassembly and assembly. Of course, in other embodiments, the rotary drive member 131 can also be fixedly connected to the carrier 11. The transmission assembly 132 can be used to transmit the rotational motion of the rotary drive member 131 to the camera 15, and convert it into a linear sliding of the camera 15. Among them, the transmission assembly 132 can be a combination of a screw rod 133 and a sleeve 134 as described below, or a combination of a first connecting rod 137 and a second connecting rod 138, or a combination of a gear 139 and a rack 140. The present application does not limit the specific structural form of the transmission assembly 132, and it is sufficient to ensure that the rotational motion of the rotating drive member 131 can be converted into linear sliding of the camera 15.

[0067] In this embodiment, the driving mechanism 13 is configured as a combination of a rotating driving member 131 and a transmission assembly 132, and the rotation axis of the rotating driving member 131 and the sliding direction of the camera 15 are arranged to intersect, so that the power source-rotating driving member 131 does not need to be arranged along the sliding direction of the camera 15, but can be arranged along the direction intersecting with the sliding direction of the camera 15. That is, at this time, the direction mutually opposite to the sliding direction of the camera 15 can be fully utilized, for example: when the camera 15 slides in the front-to-back direction, the camera 15 can be arranged in the left-right direction to improve the compactness of the camera 15 and the driving mechanism 13, which is conducive to reducing the overall volume of the camera 15 module, so as to improve the convenience of its subsequent installation in the limited space on the shell 30 of the head-mounted device 100.

[0068] Please refer to Figures 3 to 5In one embodiment of the present application, the transmission assembly 132 includes a screw rod 133 and a sleeve 134, the screw rod 133 is connected to the rotating drive member 131; an outer side of one end of the sleeve 134 is provided with a meshing tooth 135, and the meshing tooth 135 meshes with the screw rod 133; the camera 15 is accommodated in the sleeve 134, and a side circumference of the camera 15 is convexly provided with an abutment column 151; the side circumference of the sleeve 134 is provided with a pass hole 136, and the pass hole 136 extends from one end of the sleeve 134 close to the screw rod 133 to the end away from the screw rod 133 to form an arc structure, and the abutment column 151 extends into the pass hole 136. When the sleeve 134 rotates, the camera 15 can be driven to slide through the abutment cooperation between the hole wall of the pass hole 136 and the abutment column 151.

[0069] The screw rod 133 can be used to connect the rotary drive member 131, so that it can be driven to rotate by the rotary drive member 131. At the same time, the screw rod 133 can also be used to mesh with the meshing teeth 135 on the sleeve 134, so that the sleeve 134 can be driven to rotate when rotating. In order to simplify the installation of the screw rod 133, the screw rod 133 can be arranged in an integral structure with the output shaft of the rotary drive member 131. The sleeve 134 can be used to accommodate and install the camera 15, and abut and cooperate with the abutment column 151 protruding on the side surface of the camera 15 through the hole 136 set on the side circumference. In this way, when the rotary drive member 131 drives the sleeve 134 to rotate in one direction through the screw rod 133, the rotating sleeve 134 can continuously abut and squeeze the abutment column 151 through the hole 136 on the side circumference, so that the abutment column 151 can slide in a direction away from the screw rod 133, thereby realizing the extension of the camera 15 from the exposure hole 31. When the rotating driving member 131 drives the sleeve 134 to rotate in the opposite direction through the screw rod 133, the rotating sleeve 134 can continuously abut and squeeze the abutment column 151 through the hole 136 on the side circumference, so that the abutment column 151 can slide in the direction close to the screw rod 133, thereby realizing the retraction of the camera 15 from the exposure hole 31. Among them, the sleeve 134 can be a cylindrical structure with only one end open. At this time, the camera 15 can at least partially extend from the opening of one end of the sleeve 134 into the sleeve 134 for accommodation and installation, so as to be positioned by the inner wall surface of the sleeve 134 facing the opening, and the meshing teeth 135 are arranged at the end of the sleeve 134 away from the opening. Of course, the sleeve 134 can also be arranged with openings at both ends.

[0070] In this embodiment, the transmission assembly 132 is set as a combination of a screw rod 133 and a sleeve 134. On the one hand, the transmission assembly 132 can be relatively stably engaged through the meshing teeth 135 on the screw rod 133 and the sleeve 134, so as to achieve stable driving of the camera 15. On the other hand, the screw rod 133 and the sleeve 134 can be distributed very compactly at this time, and at the same time, because the camera 15 is also accommodated in the sleeve 134, the distribution between the camera 15 and the sleeve 134 can also be very compact. Therefore, the compactness of the distribution between the rotating drive member 131, the screw rod 133, the sleeve 134 and the camera 15 can be greatly improved, which is conducive to further reducing the overall volume of the camera 15 module, so as to further improve the convenience of its subsequent installation in the limited space on the housing 30 of the head-mounted device 100.

[0071] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the carrier 11 is provided with a guide groove 111 , and the guide groove 111 is extended along the sliding direction of the camera 15 , and one end of the abutment column 151 passes through the hole 136 and extends into the guide groove 111 .

[0072] In this embodiment, by providing the guide groove 111, when the abutting column 151 is abutted and driven by the passing hole 136 on the rotating sleeve 134, the guide groove 111 can guide the abutting column 151, so that it can only slide along the extension direction of the guide groove 111, thereby guiding the sliding of the camera 15, and achieving accurate and stable extension and retraction of the camera 15. Of course, in other embodiments, when the camera 15 is a square column structure or other non-circular column structure, it is also possible that the bearing member 11 is not provided with the guide groove 111, and the bearing member 11 and the bearing member 11 or other wall surfaces are abutted and limited to prevent self-rotation.

[0073] Please refer to Figure 3 and Figure 4 In one embodiment of the present application, the supporting member 11 is provided with a mounting hole 112, and the mounting hole 112 passes through two surfaces of the supporting member 11 facing each other in the sliding direction of the camera 15; the sleeve 134 is provided with a portion of the hole 136 which can be rotatably passed through the mounting hole 112, and the hole wall of the mounting hole 112 is provided with a guide groove 111.

[0074] In this embodiment, by providing a mounting hole 112 on the carrier 11, a mounting position can be provided through the mounting hole 112 so as to install a rotatable sleeve 134. At this time, the structure of the mounting hole 112 is relatively simple, and it can have a large contact area with the sleeve 134, which is conducive to improving the convenience and stability of installing the sleeve 134. On the other hand, it is also possible to directly provide a guide groove 111 on the hole wall of the mounting hole 112, which is conducive to improving the convenience of processing and forming the guide groove 111. Among them, one end of the sleeve 134 provided with the meshing tooth 135 can extend from the orifice of one end of the mounting hole 112, so as to mesh with the screw rod 133 provided on the side of the carrier 11 facing the meshing tooth 135, and the camera 15 accommodated and installed in the sleeve 134 can extend from the orifice of the other end of the mounting hole 112. In this way, the space on the back of the carrier 11 on both sides can be fully utilized, which is conducive to reducing the overall volume of the camera 15 module. Of course, in other embodiments, the meshing teeth 135 may be disposed at the end of the sleeve 134 from which the camera 15 extends. In this case, the screw rod 133 and the rotary drive member 131 are also located at the end of the carrier 11 from which the camera 15 extends.

[0075] Please refer to Figure 6 and Figure 7 In one embodiment of the present application, the transmission assembly 132 includes a first connecting rod 137 and a second connecting rod 138. One end of the first connecting rod 137 is connected to the rotating driving member 131; one end of the second connecting rod 138 is rotatably connected to an end of the first connecting rod 137 away from the rotating driving member 131, and the other end is rotatably connected to the camera 15. The second connecting rod 138 can drive the camera 15 to slide when the first connecting rod 137 is driven to rotate.

[0076] The first connecting rod 137 can be driven to rotate by the rotating driving member 131, and the opposite ends of the second connecting rod 138 are respectively connected to the first connecting rod 137 and the camera 15. Therefore, when the first connecting rod 137 is driven to rotate in one direction by the rotating driving member 131, the first connecting rod 137 can push the second connecting rod 138, and then the camera 15 is pushed by the second connecting rod 138 to achieve the extension of the camera 15 from the exposure hole 31.
