Description

A gravity compensation mechanism adapted for head-mounted equipment and a head-mounted intelligent device Technical Field

[0001] The present invention relates to the technical field of head-mounted intelligent devices, and in particular to a gravity compensation mechanism adapted for head-mounted devices and a head-mounted intelligent device. Background Art

[0002] Currently, most existing head-mounted smart devices, such as VR glasses, are heavy, with the weight concentrated in front of the user's head. These devices are typically secured to the user's head with multiple bandages, relying on the user's head to bear the entire weight. Consequently, prolonged use can cause discomfort, such as facial discomfort and neck pain. Furthermore, with concentrated weight like VR glasses, the device experiences significant inertia when the user turns their head, and without external driving force, the user experience is poor.

[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. 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 of the elastic arm is provided on the rear section. The main body, elastic arm, support pad and counterweight block are equivalent to levers, with the support pad as the fulcrum, the elastic arms on both sides of the support pad being the power arm and the resistance arm respectively, and the counterweight block and the main body's own gravity being the power and resistance respectively. According to the principle of leverage, 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 user's wearing comfort. Technical issues

[0004] The above solution reduces the pressure of the head-mounted device on the nose bridge and eyes by setting up elastic arms and using the top of the head to support the elastic arms, 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 present inventive concept and therefore it may include information that does not constitute prior art. Technical Solutions

[0006] In response to the above problem or one of the above problems, an object of the present invention 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 conditions of the head-mounted smart device.

[0007] In response to the above problem or one of the above problems, the second object of the present invention is to provide a gravity compensation mechanism adapted for a head-mounted smart device, 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; and setting a connecting member 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 object of the present invention 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 the user 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 the head-mounted smart device; and the user's head can be freely rotated without being restricted, thereby improving the user's experience of the head-mounted smart device and facilitating the promotion and use of the head-mounted smart device.

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

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

[0011] A first support member is used to be fixed on the user or on objects around the user;

[0012] a second support member, configured to be movably connected to the first support member and cooperate with the first support member to provide a support force for the head-mounted smart device to overcome gravity;

[0013] A driving unit, disposed between the first support member and the second support member, or disposed on the second support member; configured to cooperate with the vertical rotation of the user's head to provide a vertical driving force for the head-mounted smart device;

[0014] And / or, a horizontal movable rotating shaft is arranged between or within the first support member and / or the second support member; it is used to enable the second support member to rotate relative to the first support member following the rotation of the user's head when the user's head rotates horizontally.

[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 rather 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 generate 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. The word "between" in the present application should be understood as among or in the middle or in a certain spatial area or the connection between two objects; the word "within" in the present application should be understood as inside thereof. Therefore, the horizontal movable shaft of the present application can be provided at a certain part or a certain spatial area or inside of the first support member, or at a certain part or a certain spatial area or inside of the second support member, or at the connection between the first support member and the second support member. In the present application, the phrase "the second support member can rotate relative to the first support member following the rotation of the user's head" should be understood as: part or all of the second support member can rotate relative to the first support member following the rotation of the user's head.

[0017] As preferred technical measures:

[0018] The first support member includes a first support rod that can be vertically fixed to the user, and the second support member includes an L-shaped support rod or an arc-shaped support rod that can be located near the user's head;

[0020] When one end of the L-shaped support rod or the arc-shaped support rod is directly connected to the head-mounted smart device, the head-mounted smart device can be directly driven by the driving unit to swing, thereby supporting and adjusting the head-mounted smart device and improving the user experience.

[0021] Or the driving unit drives the traction rope through the winding wheel, thereby indirectly driving the head-mounted smart device; one end of the traction rope is directly connected to the driving unit, and the other end is directly connected to the head-mounted smart device; or, a guide component is provided along the traction rope or at a bend along the way, and the guide component is a pulley and / or a slideway and / or a through hole and / or a limiting protrusion and / or a groove; the driving unit is an elastic driving mechanism or a motor that can achieve force control.

[0024] As preferred technical measures:

[0025] The first support member includes a third support rod that can be vertically fixed on a chair where the user sits or on a table next to the user or a surrounding fixed object, and the second support member includes a fourth support rod that can be set above the user's head.

[0026] In this technical solution, the first support member and the second support member can be placed on a table or chair next to the user, so that the user does not have to bear the weight of the head-mounted smart device, and the user experience is better.

[0027] One end of the fourth support rod is movably connected to the third support rod, the driving unit is fixed to the fourth support rod or the third support rod, and the driving unit is connected to the head-mounted smart device by rotating the traction rope to retract and release it; the horizontal movable shaft is provided on the third support rod or the fourth support rod;

[0028] The traction rope driven by the driving unit is directly connected to the driving unit at one end and directly connected to the head-mounted smart device at the other end; or a guide component is provided along the traction rope or at a bend along the traction rope, and the guide component is a pulley and / or a slideway and / or a through hole and / or a limiting protrusion and / or a groove;

[0029] The driving unit is an elastic driving mechanism or a motor capable of realizing force control.

[0030] To achieve one of the above purposes, the second technical solution of the present invention is:

[0031] A gravity compensation mechanism adapted for a head-mounted smart device includes a first support member that can be fixed to a user or an object around the user, and a second support member that can compensate for the gravity of the head-mounted smart device;

[0032] The first support member and the second support member are relatively movably connected via a connecting member to cooperate with the movement of the user's head.

[0033] After continuous exploration and experimentation, the present invention sets 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 sets a connecting member 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, practical, and the solution is feasible.

[0034] Furthermore, the present invention can compensate for the gravity of the head-mounted smart device on the one hand by providing a first support member, a second support member and related connecting members, and can realize the change of the position and posture of the head-mounted smart device on the other hand, so that the user 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 the head-mounted smart device; and can realize the user's head to be able to rotate freely without being restricted, thereby improving the user's experience of using the head-mounted smart device and facilitating the promotion and use of the head-mounted smart device.

[0035] As preferred technical measures:

[0036] Either the first support member or the second support member is equipped with a drive unit for adjusting the vertical position and / or posture of the head-mounted smart device;

[0037] The drive unit includes one or more rotary motors, and controls the position and / or posture of the head-mounted smart device through a connecting rod or a traction rope; or, the drive unit includes at least one hydraulic rod or pneumatic rod or linear motor, and controls the position and / or posture of the head-mounted smart device through a connecting rod or a traction rope.

[0038] Preferably, the driving unit is a rotating motor, which can reduce manufacturing costs and make the structure simple and compact.

[0039] As preferred technical measures:

[0040] The first support member is a first support rod or two second support rods that can be vertically fixed to the user, or a support frame that can be placed on a surrounding object, or a ring or a belt-like structure or a hook or a suction cup or a magnetic component or a telescopic rod that can be sleeved on the user;

[0041] Preferably, the first support member is a telescopic rod, which facilitates adjustment of the vertical extension length of the first support member to suit users of different heights.

[0042] And / or, the second support member is an L-shaped support rod that can be arranged around the user's head, or two arc-shaped support rods that can be symmetrically arranged on both sides of the user's head, or an N-shaped rod, or an N-shaped bracket, or a fork-shaped structure, or a Y-shaped bracket that can be placed on the user's chest, or a rod-shaped structure, or a telescopic structure;

[0043] Preferably, the second support member is a telescopic structure, which facilitates adjustment of the lateral extension length of the second support member to suit users of different weights.

[0044] And / or, the connecting member is a hinge or a hinge or a horizontal movable shaft or a universal joint or a limiting member that enables the first support member and the second support member to rotate horizontally or a swing member with damping.

[0045] As preferred technical measures:

[0046] The first support member is a first support rod, the upper end of which is connected to the second support member, and the lower end of which is provided with a belt-like structure for being tied to the user;

[0047] The second support member is an L-shaped support rod that can be placed around the user's head, and its horizontal portion is connected to the head-mounted smart device;

[0048] The connecting member is a limiting member that enables the first supporting member and the second supporting member to rotate horizontally;

[0049] Either the first support member or the second support member is equipped with a drive unit for adjusting the vertical position of the head-mounted smart device, the drive unit including a rotary motor and a traction rope;

[0050] During use, the first support rod is fixed to the user through the belt structure. The user wears the head-mounted smart device. The weight of the head-mounted smart device is transferred to the user through the traction rope, the second support rod, and the first support rod in sequence, so as to reduce or offset the weight that the user's head needs to bear, thereby achieving gravity compensation for the head-mounted smart device.

[0051] When the user needs to turn his head, the second support member is driven to rotate on the first support member, thereby changing the horizontal position of the head-mounted smart device;

[0052] When the user needs to raise or lower his head, the traction rope moves up or down. The rotating motor senses the change of the traction rope and winds or releases the traction rope. While realizing the arbitrary posture change of the head-mounted smart device, it can also compensate for the gravity of the head-mounted smart device in time.

[0053] To achieve one of the above purposes, the third technical solution of the present invention is:

[0054] A head-mounted smart device with a gravity compensation effect includes a head-mounted smart device, a first support member that can be fixed to a user or an object around the user, 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;

[0055] The first support member and the second support member are relatively movably connected via a connecting member to cooperate with the movement of the user's head.

[0056] The present invention provides a first support member, a second support member and related connecting members, which can, on the one hand, compensate for the gravity of the head-mounted smart device, and on the other hand, realize the change of the position and posture of the head-mounted smart device, thereby allowing the user to alleviate or avoid the problems of poor user experience such as head and facial discomfort and cervical pain caused by long-term wearing of the head-mounted smart device; and can realize the user's head can rotate freely without being restricted, thereby improving the user experience of the head-mounted smart device and facilitating the promotion and use of the head-mounted smart device.

[0057] As preferred technical measures:

[0058] The first support member is a first support rod, the upper end of which is connected to the second support member, and the lower end of which is provided with a belt-like structure for being tied to the user;

[0059] The second support member is an L-shaped support rod that can be placed around the user's head, and its horizontal portion is connected to the head-mounted smart device;

[0060] The connecting member is a universal joint with damping;

[0061] When in use, the first support rod is fixed to the user through the belt structure. The user wears the head-mounted smart device. The weight of the head-mounted smart device is transferred to the user through the second support rod and the first support rod, thereby reducing or offsetting the weight that the user's head needs to bear, thereby achieving gravity compensation for the head-mounted smart device.

[0062] When the user 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, and the damping is used to position the second support member on the first support member, so that the head-mounted smart device can be changed in position at will. The solution is easy to use and manufacture. Beneficial effects

[0063] After continuous exploration and experimentation, the present invention sets 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 sets a connecting member 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, practical, and the solution is feasible.

[0064] Furthermore, the present invention provides a gravity compensation mechanism for a head-mounted smart device. This mechanism supports the head-mounted smart device by providing a first support member and a second support member. A drive unit is used to adjust the height of the head-mounted smart device, thereby alleviating the poor user experience associated with long-term wear of the head-mounted smart device, such as head and facial discomfort and cervical pain. Furthermore, to accommodate the user's head rotation, a horizontal movable shaft is added for active driving, allowing the user's head to rotate freely without restriction. This gravity compensation mechanism enhances the user's experience with the head-mounted smart device.

[0065] Furthermore, the present invention, by providing a first support member, a second support member and related connecting members, can, on the one hand, compensate for the gravity of the head-mounted smart device, and on the other hand, can realize the change of the position and posture of the head-mounted smart device, thereby allowing the user to alleviate or avoid the poor user experience such as head and facial discomfort and cervical pain caused by long-term wearing of the head-mounted smart device; and can realize the user's head to be able to rotate freely without being restricted, thereby improving the user's experience of using the head-mounted smart device and facilitating the promotion and use of the head-mounted smart device.

[0106] An eighth specific embodiment of the gravity compensation mechanism adapted for a head-mounted smart device according to the present invention:

[0107] A gravity compensation mechanism adapted for a head-mounted smart device includes a first support member that can be fixed to 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 9; the first support member and the second support member are relatively movably connected by a connecting member to cooperate with the movement of the user 10's head.

The weight of the head-mounted smart device 9 is transferred to the user 10 through the traction rope 12, the second support rod 6 and the first support rod 1 in turn, so as 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.

[0111] When the user 10 needs to turn his head, the second support member is driven to rotate on the first support member, thereby changing the horizontal position of the head-mounted smart device 9.

[0112] When the user 10 needs to raise or lower his head, the traction rope 12 is driven to move up or down, and the rotating motor senses the change of the traction rope 12 and winds or releases the traction rope. While realizing the arbitrary posture change of the head-mounted smart device 9, the gravity of the head-mounted smart device 9 can be compensated in time.

[0114] A head-mounted smart device with a gravity compensation effect includes a head-mounted smart device, a first support member that can be fixed to 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, and are used to cooperate with the movement of the user 10's head.

[0115] 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 its transverse part is connected to the head-mounted smart device, and the connecting member is a universal joint with damping.

[0116] During use, the first support rod 1 is fixed to the user 10 through the belt structure, and 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.

[0117] 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 easy to produce.

[0118] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
