For the sake of easy understanding, only the parts related to the present utility model are shown in the figure.

[0025] From Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 it can be seen that the head-mounted device of the present utility model includes a housing 11 and a main board (not shown in the figure) disposed inside the housing 11. The housing 11 is provided with a through hole 12, and further includes a support structure 20 disposed inside the housing 11, a camera module 30 slidably mounted between the support structure 20 and the through hole 12, a sliding drive mechanism for driving the camera module 30 to extend out of the housing 11 through the through hole 12 and retract from outside the housing 11 into the housing 11. An extension limiting structure is provided between the camera module 30 and the housing 11 on the circumferential side of the through hole 12, and a retraction limiting structure is provided between the camera module 30 and the support structure 20. The camera module 30 and the sliding drive mechanism are respectively electrically connected to the main board.

[0026] Specifically, the head-mounted device further includes a lens barrel module disposed inside the housing 11, a display module electrically connected to the main board, and a headband connected to the housing 11. The head-mounted device is worn on the user's head through the headband.

[0027] When the head-mounted device is not in use, the camera module 30 is located inside the housing 11, and the camera module 30 is limited inside the housing 11 under the limiting action of the retraction limiting structure, as shown in Figure 1 , Figure 2 and Figure 3 ; when the head-mounted device is in use, the camera module 30 is driven by the sliding drive mechanism to extend out of the housing 11 through the through hole 12, as shown in Figure 4 and Figure 5As shown, the camera module 30 is limited at the through hole 12 by the limitation of the protruding limiting structure, so that the camera module 30 remains in the protruding state, which can avoid the shaking between the camera module 30 and the housing 11 and affect the shooting. When in use, the camera module 30 can extend through the through hole 12 to the outside of the housing 11, and when not in use, the camera module 30 can retract into the housing 11 to avoid damaging the camera module 30. The head-mounted device of the present utility model solves the problem that the camera of the existing head-mounted device protrudes from the housing and is easily damaged, and can improve the user experience.

[0028] In the present utility model, the camera module 30 includes a carrier plate 31 and a camera 32 fixed to the carrier plate 31. The through hole 12 is correspondingly arranged with the camera 32. For example, two cameras 32 are arranged at intervals, and two through holes 12 are correspondingly arranged; a sliding connection structure is provided between the carrier plate 31 and the support structure 20 or between the carrier plate 31 and the housing 11.

[0029] Specifically, the sliding driving mechanism includes a motor 40 fixed to the support structure 20. The output shaft of the motor 40 is provided with a threaded portion, and further includes a threaded sleeve fixed to the camera module 30. The threaded portion is in threaded transmission connection with the threaded sleeve. When the motor 40 works, the output shaft rotates. Under the limitation of the sliding connection structure, relative rotation cannot occur between the carrier plate 31 and the support structure 20, and the carrier plate 31 can be driven to slide through the threaded transmission between the threaded portion and the threaded sleeve. Of course, a threaded rod coaxially arranged with the output shaft of the motor 40 can also be fixed.

[0030] The sliding connection structure includes columns 80 fixed to the support structure 20 at intervals. Mounting holes are provided on the carrier plate 31 corresponding to the columns 80. Usually, two columns 80 are provided, and two corresponding mounting holes are provided.

[0031] In order to facilitate the sliding of the camera module 30 to be more stable and avoid the camera module 30 from being skewed during sliding, resulting in the camera module 30 being stuck and unable to extend to the outside of the housing 11, sliding driving mechanisms are respectively provided on the opposite sides of the camera module 30. Usually, the two sliding driving mechanisms are respectively arranged corresponding to the two columns 80.

[0032] For the convenience of installation, a mounting plate 33 is provided on the side of the carrier plate 31, and the threaded sleeve is fixed to the mounting plate 33.

[0033] Of course, a set of sliding driving mechanisms can also be provided and correspondingly arranged at the middle parts of the support structure 20 and the carrier plate 31, which can avoid the camera module 30 from being skewed.

[0034] In some other embodiments, the sliding driving mechanism can also be set as a linear motor or an electric push rod, and the output part of the linear motor or the electric push rod is fixedly connected to the carrier plate 31.

[0035] In the present utility model, the extending limiting structure is an extending magnetic attraction structure, and the retracting limiting structure is a retracting magnetic attraction structure. When the head-mounted device is not in use, the camera module 30 can be limited inside the housing 11 through the retracting magnetic attraction structure. When the head-mounted device is in use, the camera module 30 can be limited at the through hole 12 through the extending magnetic attraction structure, so that the camera module 30 maintains an extended state.

[0036] As Figure 2 shown, an electromagnet 50 electrically connected to the main board is fixed on the carrier board 31, an extending magnetic attraction member 70 corresponding to the electromagnet 50 is fixed on the housing 11 on one side of the through hole 12, and a retracting magnetic attraction member 60 corresponding to the electromagnet 50 is fixed on the support structure 20. An extending magnetic attraction structure is formed between the electromagnet 50 and the extending magnetic attraction member 70, and a retracting magnetic attraction structure is formed between the electromagnet 50 and the retracting magnetic attraction member 60. Usually, in order to enhance the magnetic attraction force, the electromagnet 50 penetrates through the carrier board 31.

[0037] As Figure 3 shown, another implementation manner of the extending magnetic attraction structure and the retracting magnetic attraction structure is shown in the figure. Among them, the extending magnetic attraction structure includes a first carrier board magnetic attraction member 51 fixed on the carrier board 31 and an extending magnetic attraction member 70 fixed on the housing 11 on one side provided with the through hole 12. When the camera module 30 passes through the through hole 12 and extends outside the housing 11, the camera module 30 can be fixed at the through hole 12 through the magnetic attraction force between the first carrier board magnetic attraction member 51 and the extending magnetic attraction member 70; the retracting magnetic attraction structure includes a second carrier board magnetic attraction member 52 fixed on the carrier board 31 and a retracting magnetic attraction member 60 fixed on the support structure 20. When the camera module 30 retracts into the housing 11, the camera module 30 can be fixed at the support structure 20 through the magnetic attraction force between the second carrier board magnetic attraction member 52 and the retracting magnetic attraction member 60.

[0038] Specifically, the extending magnetic attraction member 70 and the retracting magnetic attraction member 60 are respectively iron sheets. Of course, the extending magnetic attraction member 70 and the retracting magnetic attraction member 60 can also be set as magnets.

[0039] In order to facilitate the fixation of the camera module 30, two groups of spaced extending limiting structures are provided between the camera module 30 and the housing 11 on one side provided with the through hole 12, and two groups of spaced retracting limiting structures are provided between the camera module 30 and the support structure 20.

[0040] Of course, the first carrier board magnetic attraction member 51 and the second carrier board magnetic attraction member 52 can also be set as electromagnets respectively electrically connected to the main board, and the corresponding extending magnetic attraction member 70 and retracting magnetic attraction member 60 are set as iron sheets or magnets.

[0041] In some other embodiments, the first carrier magnetic member 51 and the second carrier magnetic member 52 can also be directly set as magnets, and the extending magnetic member 70 and the retracting magnetic member 60 are respectively iron sheets or magnets. When the camera module 30 extends, the driving force of the sliding driving mechanism overcomes the magnetic attraction force between the second carrier magnetic member 52 and the retracting magnetic member 60, and then the two are separated, so that the camera module 30 can be continuously driven to slide; when the camera module 30 retracts, the driving force of the sliding driving mechanism overcomes the magnetic attraction force between the first carrier magnetic member 51 and the extending magnetic member 70, and then the two are separated, so that the camera module 30 can be continuously driven to slide.

[0042] In the present utility model, in order to further improve the user experience, a detection device (not shown in the figure) electrically connected to the main board is provided on the side of the housing 11 close to the user's head. After the user wears the head-mounted device, the detection device is triggered, and an electrical signal is sent from the detection device to the main board. The main board controls the electromagnet 50 to cut off the power, and the sliding driving mechanism starts to act. After the electromagnet 50 cuts off the power, the magnetic attraction force of the retraction limiting structure disappears. When the sliding driving mechanism acts, it can drive the camera module 30 to slide towards the through hole 12 until the camera module 30 passes through the through hole 12 and extends out of the housing 11. The sliding driving mechanism stops acting, and then the main board controls the electromagnet 50 to be powered on according to the delay signal or the signal that the sliding driving mechanism stops acting, so that the extending limiting structure generates a magnetic attraction force to fix the camera module 30 at the through hole 12.

[0043] Specifically, a power controller connected in series with the electromagnet 50 is provided on the main board, and the power on and off of the electromagnet 50 is controlled through the power controller. Of course, it can also be controlled through an electromagnetic switch.

[0044] Generally, the detection device is a proximity sensor, an optical fiber sensor, etc.

[0045] In some other embodiments, a control switch electrically connected to the main board can also be installed on the housing 11 for manual control by the user.

[0046] In the present utility model, the support structure 20 and the housing 11 are of a split structure and are fixed inside the housing 11. Generally, the support structure 20 is a support plate.

[0047] In some other embodiments, the support structure 20 and the housing 11 are integrally connected.

[0048] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
