For ease of explanation, only the parts relevant to the present invention are shown in the figure.

[0031] It should be noted that the directional indications (e.g., up, down, forward, backward, etc.) involved in this invention are only used to explain the relative positional relationship between the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. If the descriptions of "first", "second", etc. involved in this invention are used for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0032] Depend on Figures 1 to 8 As can be seen, the head-mounted device of the present invention includes a housing 10, a vent 11 on the housing 10, a breathable and light-blocking structure 20 disposed at the vent 11, a baffle 30 for blocking the vent 11, and an adjustment structure 40 installed on the housing 10 for driving the baffle 30 to block the vent 11 / remove from the vent 11.

[0033] In the initial state, the baffle 30 is sealed at the vent 11. When the user's face feels stuffy, the baffle 30 is driven to detach from the vent 11 by the adjustment structure 40, which can form a heat dissipation channel at the vent 11 and the breathable light-blocking structure 20, thus dissipating heat from the enclosed space formed on the user's face. Moreover, the breathable light-blocking structure 20 at the vent 11 can block light at the vent 11 while achieving heat dissipation, thereby ensuring the sealing performance of the enclosed space formed on the user's face. The head-mounted device of this embodiment solves the problem of stuffiness on the user's face when wearing a head-mounted device, and can improve the wearing experience and comfort.

[0034] In this embodiment of the invention, in order to facilitate installation, an installation plate 50 is slidably installed inside the cavity formed by the outer shell 10, and a transmission mechanism is provided between the adjustment structure 40 and the installation plate 50; the baffle 30 is fixedly connected to the installation plate 50.

[0035] Specifically, the adjustment structure 40 is a knob that is rotatably mounted on the housing 10; the transmission mechanism includes a gear 61 that is coaxially arranged and fixedly connected to the knob, and a rack 62 that is arranged on the mounting plate 50.

[0036] In some other embodiments, the transmission mechanism may also be configured as follows: a driving pulley coaxially and fixedly connected to the knob, a driven pulley spaced apart from the driving pulley, and a transmission belt surrounding the driving pulley and the driven pulley, wherein the mounting plate 50 is fixedly connected to the transmission belt.

[0037] In this embodiment of the invention, a limiting plate 70 is provided on the side of the mounting plate 50 away from the vent 11, and is fixedly installed inside the cavity enclosed by the outer shell 10. At least two elastic telescopic structures 80 are provided between the mounting plate 50 and the limiting plate 70, spaced apart along the sliding direction of the mounting plate 50. The at least two elastic telescopic structures 80 are fixedly connected to the mounting plate 50 or the limiting plate 70. The elastic force of the at least two elastic telescopic structures 80 can make the baffle 30 fit tightly against the inner wall of the outer shell 10, which can keep the baffle 30 in the adjusted position and prevent the mounting plate 50 and the baffle 30 from shaking.

[0038] Depend on Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 It is known that a guide structure is provided between the mounting plate 50 and the outer shell 10 along the sliding direction of the mounting plate 50, which plays a guiding role when the mounting plate 50 and the baffle 30 slide.

[0039] Specifically, the guide structure includes a groove 12 provided on the inner wall of the housing 10 and a sliding structure fixedly connected to the mounting plate 50, the sliding structure being inserted into the groove 12. Typically, the groove 12 is a groove protruding from the inner wall of the housing 10; however, the groove 12 can also be a recess provided on the inner wall of the housing 10.

[0040] Specifically, the sliding structure includes at least two guide posts 51 spaced apart along the sliding direction of the mounting plate 50, and the at least two guide posts 51 are fixedly connected to the mounting plate 50 respectively.

[0041] Furthermore, the breathable and light-shielding structure 20 is disposed on the outside of the outer shell 10 and covers the vent 11. The shape of the baffle 30 is adapted to the shape of the vent 11. A receiving groove 13 is provided on the bottom of the groove 12 corresponding to each guide post 51. The groove wall of the receiving groove 13 is set in an inclined shape. When the baffle 30 slides to the position directly opposite the vent 11, at least two guide posts 51 are aligned with the corresponding receiving grooves 13. Under the elastic force of the elastic telescopic structure 80, at least two guide posts 51 are respectively inserted into the corresponding receiving grooves 13 and the baffle 30 is inserted into the vent 11. It can enhance the sealing effect of the vent 11. The baffle 30 can be inserted into the vent 11 to support the ventilated light-blocking structure 20 and prevent it from being crushed. When ventilation and heat dissipation are needed, the knob can be turned. Through the cooperation of gear 61 and rack 62, the mounting plate 50 can be driven to slide. When the mounting plate 50 slides, at least two guide posts 51 slide synchronously. Since the groove wall of the receiving groove 13 is set to be inclined, when at least two guide posts 51 slide out of the receiving groove 13, they can push the mounting plate 50 to move towards the side closer to the limiting plate 70, and drive the baffle 30 to disengage from the vent 11.

[0042] Specifically, there are three guide posts 51; there are three corresponding receiving slots 13, and two of the receiving slots 13 are respectively located on opposite sides of the vent 11.

[0045] Specifically, for ease of installation, the elastic telescopic structure 80 also includes a sleeve 83. The plunger rod 81 is slidably installed inside the sleeve 83, and an elastic element is disposed between the end of the plunger rod 81 located inside the sleeve 83 and the bottom of the sleeve 83. The sleeve 83 is fixedly installed inside the pipe body 52. ​​To prevent the plunger rod 81 from coming out of the sleeve 83, a limiting ring is provided at the opening of the sleeve 83, and the end of the plunger rod 81 located inside the sleeve 83 is shaped like a dome.

[0046] Typically, the baffle 30 is located on one side of the mounting plate 50, and a support plate 53 is connected between the mounting plate 50 and the baffle 30. The slide groove 12 is located on the side of the vent 11 to avoid interference between the slide groove 12 and the vent 11.

[0047] In this embodiment of the invention, the vent 11 is an elongated through hole, and the breathable and light-shielding structure 20 is a mesh layer attached to the outer side of the outer shell 10.

[0048] Specifically, a recessed area is provided on the outer side of the outer shell 10 around the vent 11, and the mesh layer is fixedly installed inside the recessed area.

[0049] Typically, the mesh layer is fixed by means of bonding, hot pressing, etc.
