Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of head-mounted smart devices, particularly to a gravity compensation mechanism adapted to a head-mounted smart device and a head-mounted smart device. STATE OF THE ART

[0002] Currently, most existing head-mounted smart devices such as VR headsets are heavy. The weight is concentrated in front of the user's head and is generally fixed to the user's head by multiple bandages. The weight of the entire head-mounted smart device is borne by the user's head. Therefore, prolonged use will cause facial discomfort, neck pain, and other unpleasant experiences for the user. Head-mounted smart devices with concentrated weight, such as VR headsets, have large inertia when the user turns their head. Since there is no external force to drive and support them, the user experience is also poor.

[0003] In addition, the Chinese patent (announcement number: CN213957751U) provides a headset wherein a spring arm on the user's head is added to the headset body. The spring arm has a front segment and a rear segment connected in series. The front segment is connected to the top of the body and extends above the body, and the rear segment extends from the end of the front segment to the rear of the body. A support pad is arranged on the inside of the front segment, raised toward the rear of the body. A counterweight block is arranged on the rear segment and is movable in the longitudinal direction of the spring arm. The body, the spring arm, the support pad, and the counterweight block correspond to a lever, and the support pad is the fulcrum. The spring arms on both sides of the support pad are force arms and resistance arms, respectively.The inherent gravity of the counterweight block and the body is the force or resistance. According to the lever principle, an upward force is exerted on the body, which can reduce pressure on the bridge of the nose and eyes and improve the wearer's comfort. CONTENT OF THE PRESENT INVENTIONTechnical Problems

[0004] The above solution reduces the pressure of the headset on the bridge of the nose and eyes by adjusting the spring arm and supporting the spring arm above the head. However, this reduction effect is very limited and further increases the pressure on the head, which also causes discomfort to the user, resulting in a poor user experience and is not conducive to the promotion and use of head-mounted smart devices.

[0005] The information disclosed in the prior art serves only as a background for understanding the inventive concept and may therefore contain information that does not form part of the prior art. Technical solutions

[0006] In view of the above problems or one of the above problems, the purpose I of the present invention is to provide a gravity compensation mechanism adapted to a head-mounted smart device so that support and adjustment can be actively provided according to the usage status of the head-mounted smart device.

[0007] In view of the above-mentioned problems or one of the above-mentioned problems, the purpose II of the present invention is to provide a gravity compensation mechanism adapted to a head-mounted smart device. The first support member and the second support member are arranged such that the weight of the head-mounted smart device is transferred to the user's body or to objects around the user to reduce or completely counteract the weight borne by the user's head, thus realizing gravity compensation of the head-mounted smart device.The connecting piece is arranged so that the first support member and the second support member can be relatively rotated, so that the head-mounted smart device can move with the movement of the user's head, which has a simple structure and a practical and practicable solution.

[0008] In view of the above-mentioned problems or one of the above-mentioned problems, the purpose III of the present invention is to provide a gravity compensation mechanism adapted to a head-mounted smart device and a head-mounted smart device. The first support member, the second support member, and the associated connecting pieces are arranged to compensate for the gravity of the head-mounted smart device on the one hand, and to realize the position and attitude change of the head-mounted smart device on the other. This alleviates or prevents problems with poor user experience such as head and facial discomfort and cervical vertebrae pain caused by users wearing head-mounted smart devices for a long time.The user's head can be rotated freely without restrictions, thereby improving the user's experience in using head-mounted smart devices, which is conducive to the promotion and use of head-mounted smart devices.
