Description

Technical Field

[0001] The utility model relates to the technical field of head-mounted intelligent equipment, and in particular to a gravity compensation mechanism adapted to the head-mounted equipment and a head-mounted intelligent device. 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 usually fixed to the user's head by multiple bandages, and rely 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 user experience such as facial discomfort and neck pain. In addition, head-mounted smart devices with concentrated weight, such as VR glasses, have large inertia when the user turns his head, and the user experience is also poor due to the lack of external force driving support.

[0003] Furthermore, the Chinese patent (publication number: CN213957751U) provides a head-mounted device, in which an elastic arm located on the user's head is added to the main body of the head-mounted device, and the elastic arm includes a front section and a rear section connected in sequence, the front section is connected to the top of the main body and extends upward from the main body, and the rear section extends from the end of the front section to the rear of the main body. A support pad protruding toward the rear of the main body is provided on the inner side of the front section, and a counterweight block movable along the length direction of the elastic arm is provided on the rear section. The main body, elastic arm, support pad and counterweight block are equivalent to a lever, the support pad is a fulcrum, the elastic arms on both sides of the support pad are respectively a power arm and a resistance arm, and the self-gravity of the counterweight block and the main body are respectively a power and a resistance. According to the principle of the lever, an upward force will be applied to the main body, thereby reducing the pressure on the bridge of the nose and the eyes, and improving the comfort of the user's wearing.

[0004] The above scheme reduces the pressure of the head-mounted device on the bridge of the nose and the eyes by setting up an elastic arm and using the top of the head to support the elastic arm, but this reduction effect is very limited, and the increased pressure on the top of the head will also cause discomfort to the user, resulting in a poor user experience, which is not conducive to the promotion and use of head-mounted smart devices.

[0005] 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

[0006] 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 mechanism adapted to a head-mounted smart device, which can actively provide support and adjustment according to the usage status of the head-mounted smart device.

[0007] 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 mechanism adapted for a head-mounted smart device, by setting a first support member and a second support member to transfer the weight of the head-mounted smart device to the user or surrounding objects, so as to reduce or completely offset the weight that the user's head needs to bear, thereby realizing gravity compensation of the head-mounted smart device; and a connecting member is set so that the first support member and the second support member can rotate relative to each other, so that the head-mounted smart device can move with the movement of the user's head. The structure is simple and practical, and the solution is feasible.

[0008] In response to the above problem or one of the above problems, the third purpose of the utility model is to provide a gravity compensation mechanism and a head-mounted smart device adapted for a head-mounted smart device. Through a first support member, a second support member and related connecting members, on the one hand, the gravity of the head-mounted smart device can be compensated, and on the other hand, the position and posture of the head-mounted smart device can be changed, so that users can alleviate or avoid 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; and the user's head can be freely rotated without being restricted, thereby improving the user's user experience of the head-mounted smart device and facilitating the promotion and use of head-mounted smart devices.

[0009] To achieve one of the above purposes, the first technical solution of the utility model is:

[0010] A gravity compensation mechanism adapted for a head-mounted smart device, comprising:

[0015] Furthermore, the driving unit described in the present application provides a vertical driving force for the head-mounted smart device, which does not mean that the driving unit can only provide a vertical driving force, but that the power provided by the driving unit can be decomposed into a vertical driving force, that is, in some scenarios, it can also include driving forces in other directions. For example, the power provided by the driving unit can be an upward inclined driving force, thereby allowing the head-mounted smart device to produce an upward inclined movement, and thus the vertical movement trend can be decomposed.

[0016] Similarly, the vertical rotation tendency of the user's head described in the present application does not mean that the head moves only in the vertical direction, but means that the movement direction of the head can be decomposed into vertical displacement, such as when the user raises his head.

[0116] A head-mounted smart device with a gravity compensation effect comprises a head-mounted smart device, a first support member that can be fixed on a user 10 or an object around the user 10, and a second support member that can compensate for the gravity of the head-mounted smart device; the head-mounted smart device is connected to the second support member; the first support member and the second support member are relatively movably connected via a connecting member, so as to cooperate with the movement of the user 10's head.

[0117] The first support member is a first support rod 1, the upper end of which is connected to the second support member, and the lower end of which is provided with a belt structure for binding on the user 10; the second support member is an L-shaped support rod 2 that can be wrapped around the head of the user 10, and the transverse part of which is connected to the head-mounted smart device, and the connecting member is a universal joint with damping.

[0118] When in use, the first support rod 1 is fixed to the user 10 through the belt structure. The user 10 wears the head-mounted smart device. The weight of the head-mounted smart device is transferred to the user 10 through the second support rod 6 and the first support rod 1 to reduce or offset the weight that the user 10 head needs to bear, thereby realizing gravity compensation of the head-mounted smart device 9.

[0119] When the user 10 needs to turn his head or raise or lower his head, the second support member is driven to overcome the resistance of the universal joint, so that the second support member produces a corresponding action on the first support member, thereby realizing the arbitrary posture change of the head-mounted smart device. The solution is easy to use and manufacture.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
