Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of electronic devices, and more specifically, to head-mounted devices. Background Art

[0002] For near-eye display devices such as head-mounted devices (for example, virtual reality (VR) glasses), efficient heat dissipation is required while taking into account wearing comfort. For the requirement of efficient heat dissipation, head-mounted devices usually adopt air-cooling heat dissipation solutions. Due to the action of the fan sucking in air, the pre-designed heat dissipation holes (for example, air inlets) will suck in air from the outside of the device, which will also cause the gap between the lens barrel and the shell to inhale air. This will then cause the flowing airflow to pass through or blow towards the eyes (because the human eye is located directly above the lens barrel), causing the wearer's eyes to become dry and uncomfortable, ultimately resulting in a reduced wearing experience. In addition, the gap between the lens barrel and the shell will also cause debris and dust to be sucked in, causing damage to the internal electrical parts. Therefore, further improvements in this regard are expected. Summary of the invention

[0003] This summary is provided to introduce concepts in a brief form that will be described in detail in the detailed description below. This summary is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0004] To solve the above problems, an embodiment of the present disclosure provides a head-mounted device, comprising: a shell; a heat dissipation port, which is arranged on the shell; a first lens barrel and a second lens barrel, wherein the shell comprises an opening for installing the first lens barrel and the second lens barrel, and the opening is larger than the outer diameter of the first lens barrel and the second lens barrel, so that the first lens barrel and the second lens barrel are allowed to move in the opening, and the distance between the first lens barrel and the second lens barrel is adjustable; an elastic material is arranged in parts of the opening between the first lens barrel and the shell and between the second lens barrel and the shell, and seals the opening between the first lens barrel and the shell and between the second lens barrel and the shell.

[0005] By inserting elastic material into the openings between the first lens barrel and the shell and between the second lens barrel and the shell for sealing, on the one hand, the flow of air generated by the fan sucking in air in the openings is blocked, eliminating the discomfort to the eyes caused by the movement of air flow; on the other hand, it will not affect the adjustment of the first lens barrel and the second lens barrel, and can achieve good sealing throughout the whole process.

[0016] Figure 1 A schematic diagram of air flow for air cooling and heat dissipation according to some embodiments is shown. Figure 2 1 shows a schematic diagram of a portion of a head mounted device according to some embodiments. Figure 1 and Figure 2 As shown, the head mounted device includes a housing 10, a heat dissipation port (not shown), a first lens barrel 11 and a second lens barrel 12, and an elastic material 14. In some embodiments, the heat dissipation port is provided on the housing to facilitate internal heat dissipation of the head mounted device. Typically, the heat dissipation port is provided on both sides of the head mounted device (e.g., the left and right sides in the wearing state) to facilitate the inflow and outflow of air, the inflow of fresh air, and the outflow of air with the dissipated heat.

[0017] like Figure 1 and Figure 2 As shown, in some embodiments, the housing 10 includes an opening 13 for mounting the first lens barrel 11 and the second lens barrel 12, and the opening 13 is larger than the outer diameter of the first lens barrel 11 and the second lens barrel 12, so that the first lens barrel 11 and the second lens barrel 12 are allowed to move in the opening 13, and the distance between the first lens barrel 11 and the second lens barrel 12 is adjustable to accommodate different pupil distances of different users. In some embodiments, the first lens barrel 11 and the second lens barrel 12 are embedded or snapped onto the housing 10, and the distance between the first lens barrel 11 and the second lens barrel 12 is adjusted using an adjustment component.

[0018] like Figure 1 As shown, due to the air cooling of the head mounted device, there is air flow in the opening 13, which can easily cause dry eyes and affect the user experience. Figure 2 As shown, the elastic material 14 is disposed in the portion of the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10 to seal the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10. In this way, on the one hand, the flow airflow generated by the air sucked in by the fan in the opening is blocked, eliminating the discomfort to the eyes caused by the airflow movement; on the other hand, it will not affect the adjustment of the first lens barrel and the second lens barrel, and can achieve good sealing of the whole process.

[0019] In some embodiments, Figure 3As shown, when the first lens barrel 11 and the second lens barrel 12 are centered, the portions of the opening 13 located between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10 are both annular, and the width of the annular shape is 3 mm to 5 mm. In some embodiments, the distance between the first lens barrel 11 and the second lens barrel 12 can be adjusted by moving the first lens barrel 11 and the second lens barrel 12 toward or away from each other from the centered state by a maximum distance of 2.5 mm to 4.5 mm, as shown in FIG. Figure 4 and Figure 5 For example, when the first lens barrel 11 and the second lens barrel 12 are moved toward each other by 3.5 mm from the centered state, the distance between the first lens barrel 11 and the second lens barrel 12 can be reduced by 7 mm; when the first lens barrel 11 and the second lens barrel 12 are moved away from each other by 3.5 mm from the centered state, the distance between the first lens barrel 11 and the second lens barrel 12 can be increased by 7 mm.

[0020] In some embodiments, during the adjustment of the first lens barrel 11 and the second lens barrel 12, the elastic material 14 keeps sealing the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10, thereby preventing airflow from passing through the opening 13. In some embodiments, the elastic material 14 is in a ring shape around the first lens barrel 11 or the second lens barrel 12, and the initial thickness of the elastic material 14 is greater than or equal to the thickness of the opening 13 between the first lens barrel 11 and the housing 10 or between the second lens barrel 12 and the housing 10 plus the maximum distance moved by the first lens barrel 11 or the second lens barrel 12 from the centered state. In this way, when the first lens barrel 11 or the second lens barrel 12 moves the maximum distance from the centered state (for example, toward the middle), the elastic material 14 near the middle is in an extreme compression state, and the elastic material 14 on the opposite side (outer side) is in a slightly compressed state to ensure good sealing of the opening 13 (that is, good fit between the first lens barrel 11, the second lens barrel 12 and the elastic material 14).

[0021] In some embodiments, the elastic material 14 includes a foam material, for example, a foam material from Nitto or Rogers, but the present disclosure is not limited thereto. In some embodiments, when the compression rate is in the range of 20% to 80%, the compression hardness of the elastic material 14 is 0.3 N / cm 2 Up to 2N / cm 2 If the compression hardness of the elastic material 14 is too small, it is not conducive to promoting a better sealing of the opening 13; if the compression hardness of the elastic material 14 is too large, the resistance during the adjustment of the first lens barrel 11 and the second lens barrel 12 is too large, which is not conducive to improving the control experience. In some embodiments, when the compression rate is in the range of 25% to 50%, the compression hardness of the elastic material 14 is 0.33N / cm 2 Up to 0.45N / cm 2In this way, good sealing of the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10 can be achieved, and the adjustment and control of the first lens barrel 11 and the second lens barrel 12 are facilitated.

[0022] In some embodiments, the elongation at break of the elastic material 14 is 400% to 500%. By adopting the elastic material 14 with the elongation at break of 400% to 500%, during the adjustment operation of the first lens barrel 11 and the second lens barrel 12, the elastic material 14 can achieve good resilience, thereby facilitating good sealing of the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10.

[0023] In some embodiments, the tensile strength of the elastic material 14 is 7 N / cm 2 Up to 9N / cm 2 By adopting a tensile strength of 7N / cm 2 Up to 9N / cm 2 The elastic material 14 can achieve good rebound during the adjustment and manipulation of the first lens barrel 11 and the second lens barrel 12, thereby facilitating good sealing of the opening 13 between the first lens barrel 11 and the housing 10 and between the second lens barrel 12 and the housing 10.

[0024] In some embodiments, the density of the elastic material 14 is 0.1 g / cm 3 Up to 0.2g / cm 3 This is conducive to the lightweight design of head-mounted devices.
