Description

Technical Field

[0001] The utility model relates to the technical field of head-mounted intelligent equipment, and in particular to a gravity compensation component with a counterweight and a head-mounted device without a sense of biased weight. Background Art

[0002] At present, most of the existing head-mounted smart devices such as VR glasses are heavy, and the weight is concentrated in front of the user's head. They are generally fixed to the user's head by multiple bandages, relying on the user's head to bear the weight of the entire head-mounted smart device. Therefore, after long-term use, it will bring uncomfortable experience to the user such as head discomfort and neck pain, and will have a strong sense of heaviness or heaviness, which will cause user disgust, resulting in poor user experience, and is not conducive to the promotion and use of head-mounted smart devices.

[0003] Furthermore, for head-mounted smart devices with concentrated weight, such as VR glasses, the device has large inertia when the user turns the head. Since there is no external force to drive and support, the user experience is also poor.

[0004] The information disclosed in this background art is only for understanding the background of the concept of the present invention and therefore it may include information that does not constitute the prior art. Utility Model Content

[0005] In response to the above problem or one of the above problems, an object of the present utility model is to provide a gravity compensation component with a counterweight and a head-mounted device without a sense of weight imbalance. By providing the counterweight, the unoffset weight of the head-mounted smart device is prevented from being concentrated in the front or side of the user's head, thereby effectively preventing the user from having a sense of weight imbalance or heaviness when using the head-mounted smart device; at the same time, the inertia of the device can be effectively reduced, so that the user can more flexibly adjust the posture of the head-mounted smart device, so that the user has a better user experience, which is conducive to the promotion and use of head-mounted smart devices.

[0006] In response to the above problem or one of the above problems, the second purpose of the utility model is to provide a gravity compensation component with a counterweight, which transfers the weight of the head-mounted smart device to the user or surrounding objects by setting a first support member and a second support member to reduce or completely offset the weight that the user's head needs to bear, thereby achieving gravity compensation for the head-mounted smart device, thereby effectively solving the problems of poor user experience such as head and facial discomfort and cervical pain caused by long-term wearing of head-mounted smart devices.
