Description

Gravity compensation assembly with counterweight and head-mounted device without weight bias Technical Field

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

[0002] At present, most 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 cause users to have uncomfortable head discomfort, neck pain and other uncomfortable user experiences, and will have a strong sense of heaviness or heaviness, which will cause user disgust and lead to poor user experience, which 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 it, 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 prior art. Technical Solutions

[0005] In response to the above problem or one of the above problems, one purpose of the present invention 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 sinking when using the head-mounted smart device; at the same time, it can effectively reduce the inertia of the device, allowing the user to 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 present 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 of 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.

[0014] Furthermore, when the first support member and the second support member cannot completely offset the gravity and pressure that the user's head needs to bear, the utility model arranges a counterweight member on the second support member to balance the force of the entire structure, which can effectively avoid the unoffset or uncompensated weight of the head-mounted smart device from being concentrated in front of the user's head, thereby avoiding the user from feeling heavy or sinking when using or wearing the relevant smart device; at the same time, it can effectively reduce the inertia of the device, allowing the user to 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.

[0015] Furthermore, in order to cooperate with the rotation of the user's head, the utility model adds a horizontal movable shaft for active cooperation driving, so that the user's head can rotate freely without being restricted, thereby further improving the user's experience of using the head-mounted smart device.
