Description

[Technical Field]

[0001] The present invention relates to the technical field of head-mounted smart devices, and more particularly to a gravity compensation mechanism adapted for head-mounted devices and a head-mounted smart device. [Background technology]

[0002] Currently, conventional head-mounted smart devices such as VR glasses are usually heavy and concentrated on the front of the user's head. They are generally secured to the user's head with multiple straps, and the user's head bears the entire weight of the head-mounted smart device. Therefore, after prolonged use, the user may experience discomfort in the face, neck pain, and other unpleasant experiences. Furthermore, when a user rotates their head with a head-mounted smart device such as VR glasses, the device's inertia is large and there is no external force to drive or support it, resulting in a poor experience.

[0003] Furthermore, a Chinese patent (publication number: CN213957751U) provides a head-mounted device, in which the main body of the head-mounted device is further provided with an elastic arm that is placed on the user's head. The elastic arm includes a front segment and a rear segment connected in sequence. The front segment is connected to the top of the main body and extends upward toward the main body, and the rear segment extends from the end of the front segment toward the rear of the main body. A support pad is provided on the inside of the front segment, protruding toward the rear of the main body, and a weight block is provided on the rear segment, which is movable along the length of the elastic arm. The main body, elastic arm, support pad, and weight block correspond to a lever, with the support pad as the fulcrum, the elastic arms on both sides of the support pad as the power arm and the resistance arm, respectively, and the gravity of the weight block and the main body itself as the power arm and resistance arm, respectively. Based on the lever principle, an upward acting force is applied to the main body, thereby reducing pressure on the bridge of the nose and eyes and improving user comfort. Summary of the Invention [Problem to be solved by the invention]

[0004] In the above solution, an elastic arm is provided, and support for the elastic arm above the head is provided to reduce the pressure on the bridge of the nose and eyes of the head-mounted device. However, the reduction effect is very limited and further increases the pressure above the head, causing discomfort to the user, resulting in a poor user experience and being detrimental to the widespread use of head-mounted smart devices.

[0005] The information disclosed in this Background Art section is merely used to understand the background of the concept of the present invention and may include information that does not constitute prior art.

[0006] To address the above problem or one of the above problems, the present invention aims to provide a gravity compensation mechanism adapted to a head-mounted smart device, which can provide support and adjustment automatically based on the usage situation of the head-mounted smart device.

[0007] To address the above problems or one of the above problems, the present invention aims to provide a gravity compensation mechanism suitable for head-mounted smart devices. By arranging a first support member and a second support member, the weight of the head-mounted smart device can be transferred to the user's body or surrounding objects, thereby reducing or completely canceling the weight that needs to be borne by the user's head, thereby realizing gravity compensation for the head-mounted smart device. Furthermore, by arranging a connecting member, the first support member and the second support member can be rotated relative to each other, allowing the head-mounted smart device to move along with the movement of the user's head. The structure is simple and practical, and the solution can be implemented appropriately.

[0008] To address the above problems or one of the above problems, the present invention aims to provide a gravity compensation mechanism and a head-mounted smart device suitable for head-mounted smart devices, which can compensate for the gravity of the head-mounted smart device through the first support member, the second support member and the related connecting member, while realizing the change of the position and posture of the head-mounted smart device, so that users can alleviate or avoid the problems of poor experience such as discomfort in the head and face and pain in the cervical spine caused by wearing a head-mounted smart device for a long period of time, and the user's head can be rotated freely without being restricted, improving the user's experience with head-mounted smart devices and contributing to the widespread use of head-mounted smart devices. [Means for solving the problem]

[0009] In order to achieve one of the above objectives, the first technical solution of the present invention is as follows: A gravity compensation mechanism adapted for a head-mounted smart device, comprising: a first support member that is fixed to the user's body or an object around the user; a second support member movably connected to the first support member relative to the first support member and cooperating with the first support member to provide a support force for overcoming gravity to the head-mounted smart device; a drive unit provided between the first support member and the second support member or on the second support member, which cooperates with the vertical rotation of the user's head to provide a vertical driving force to the head-mounted smart device; and / or a horizontally movable rotation axis provided between or within the first support member and / or the second support member, which, when the user's head rotates horizontally, enables the second support member to rotate relative to the first support member in accordance with the rotation of the user's head.

[0010] Furthermore, the fact that the driving unit described in this application provides a vertical driving force to the head-mounted smart device does not mean that the driving unit can only provide a vertical driving force, but that the vertical driving force can be resolved from the force provided by the driving unit, that is, in some scenes, driving forces in other directions may be included, for example, the force provided by the driving unit may be a driving force to tilt upward, thereby causing the head-mounted smart device to generate an upward tilting motion and further resolve the vertical motion tendency.

[0011] Similarly, the vertical rotation tendency of the user's head described herein does not mean that the head moves only vertically, but that vertical displacement can be resolved from the direction of head movement, such as when the user looks up. The term "between" in this application should be understood as "inside," "middle," "middle," "a spatial region," or "the connection point between two objects," and the term "inside" in this application should be understood as "inside." Therefore, the horizontally movable rotation axis in this application may be located at a certain portion, a certain spatial region, or the interior of the first support member, or at a certain portion, a certain spatial region, or the interior of the second support member, or at the connection point between the first and second support members. In this application, "the second support member is rotatable relative to the first support member as the user's head rotates" means that a part or the entire second support member is rotatable relative to the first support member as the user's head rotates.

[0012] Suitable technical measures include: The first support member includes a first support rod that can be fixed to the user's body in a vertical direction, and the second support member includes an L-shaped support rod or an arc-shaped support rod that can be positioned near the user's head, One end of the L-shaped support rod or arc-shaped support rod is directly or indirectly connected to the head-mounted smart device, and the other end is connected to the first support rod by the driving unit, and the indirect connection between the L-shaped support rod or arc-shaped support rod and the head-mounted smart device is an indirect connection via a flexible material or a towing rope.

[0013] When one end of the L-shaped support rod or arc-shaped support rod is directly connected to the head-mounted smart device, the head-mounted smart device is directly driven by the driving unit to swing, thereby supporting and adjusting the head-mounted smart device and improving the user experience.

[0014] Alternatively, the driving unit drives the towing rope through a reel to indirectly drive the head-mounted smart device, one end of the towing rope is directly connected to the driving unit and the other end is directly connected to the head-mounted smart device, or the towing rope is provided with a guide module at the middle or at the bending point along the way, the guide module being a pulley, or / and a sliding rail, or / and a through hole, or / and a position limiting protrusion, or / and a groove, and the driving unit is an elastic driving mechanism or a motor capable of realizing force control.

[0016] Suitable technical measures include: The first support member is vertical and includes a third support rod that can be fixed to the chair on which the user is sitting, or to a table next to the user, or to a fixed object in the vicinity, and the second support member includes a fourth support rod that can be positioned above the user's head.

[0017] In this technical solution, the first support member and the second support member are placed on a table or chair next to the user, so that the user himself does not bear the weight of the head-mounted smart device, improving the user's experience.

[0018] 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, the driving unit is connected to the head-mounted smart device by winding and releasing a towing rope to rotate, and the horizontally movable rotation axis is provided on the third support rod or the fourth support rod; The towing rope driven by the driving unit has one end directly connected to the driving unit and the other end directly connected to the head-mounted smart device, or the towing rope is provided with a guide module at the midpoint or at the bending point, and the guide module is a pulley, or / and a sliding rail, or / and a through hole, or / and a position limiting protrusion, or / and a recess; The drive unit is an elastic drive mechanism or a motor capable of realizing force control.

The structure is simple and practical, and the solution can be implemented appropriately.

[0021] Furthermore, in this invention, by arranging the first support member, the second support member and the related connecting member, the gravity of the head-mounted smart device can be compensated for, while the position and posture of the head-mounted smart device can be changed, so that the user can alleviate or avoid problems such as discomfort in the head and face and pain in the cervical spine caused by wearing the head-mounted smart device for a long period of time, and the user's head can be rotated freely without being restricted, improving the user's experience with the head-mounted smart device and contributing to the widespread use of head-mounted smart devices.

[0026] And / or, the connecting member is a hinge, or a hinged part, or a horizontally movable rotation axis, or a universal joint, or a position limiting member that allows the first support member and the second support member to rotate horizontally, or a swing member with damping.

The weight of the head-mounted smart device is transmitted to the user's body through the towing rope, the second support rod, and the first support rod in sequence, thereby reducing or offsetting the weight that needs to be borne by the user's head and realizing gravity compensation for the head-mounted smart device; When the user needs to turn around, the second support member is rotated relative to the first support member to change the horizontal position of the head-mounted smart device; When the user needs to look up or down, the tow rope moves up or down, and the rotary motor detects the change in the tow rope and winds or releases the tow rope, thereby realizing any change in the posture of the head-mounted smart device and instantly compensating for the gravity of the head-mounted smart device.

[0028] In order to achieve one of the above objectives, the third technical solution of the present invention is as follows: A head-mounted smart device with gravity compensation effect, comprising: a head-mounted smart device; a first support member that can be fixed to a user's body or an object around the user; and a second support member that can compensate for gravity of the head-mounted smart device, the first support member being connected to the head-mounted smart device and the second support member; The first support member and the second support member are connected by a connecting member so as to be relatively movable, and cooperate with each other in the movement of the user's head.

[0029] In this invention, by arranging the first support member, the second support member and the related connecting member, the gravity of the head-mounted smart device can be compensated for, while the position and posture of the head-mounted smart device can be changed, so that the user can alleviate or avoid problems such as discomfort in the head and face and pain in the cervical spine caused by wearing the head-mounted smart device for a long time, and the user's head can be rotated freely without being restricted, improving the user's experience with the head-mounted smart device and contributing to the widespread use of head-mounted smart devices.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated items.

[0039] As shown in FIGS. 1 and 2, a first specific embodiment of the gravity compensation mechanism adapted to the head-mounted smart device of the present invention is as follows: The gravity compensation mechanism is adapted for a head-mounted smart device and includes a first support member, a second support member, a drive unit (3), and a horizontally movable rotation shaft (4).

[0040] The first support member is fixed to the body of the user 10 or an object around the user 10, and the second support member is movably connected to the first support member relative to the first support member and cooperates with the first support member to provide the head-mounted smart device 9 with a supporting force that overcomes gravity.

[0041] The drive unit 3 is disposed between the first support member and the second support member, and provides a vertical driving force to the head-mounted smart device 9 based on the tendency of the user's 10 head to rotate vertically.

[0042] The horizontally movable rotation shaft 4 is provided on the second support member, and when the head of the user 10 rotates in the horizontal direction, the second support member rotates relative to the first support member in conjunction with the rotation of the head of the user 10.

[0043] The first support member includes a first support rod 1 fixed vertically to the body of the user 10, and the second support member includes an L-shaped support rod 2 provided above the head of the user 10, one end of the L-shaped support rod 2 being connected to a head-mounted smart device 9 and the other end being connected to the first support rod 1.

[0044] In this embodiment, the present invention adjusts the height of the head-mounted smart device 9 by directly driving the second support member with the driving unit 3 or by using a traction rope module, thereby improving the experience of the user 10.

In this embodiment, the third support rod 7 and the fourth support rod 8 are placed on the table next to the user 10, so that the weight of the head-mounted smart device 9 is not supported by the user 10 himself, which improves the experience of the user 10.

[0051] As shown in FIG. 8, the sixth specific embodiment of the gravity compensation mechanism adapted to the head-mounted smart device of the present invention is as follows: The main differences between this embodiment and the fifth specific embodiment are as follows: the horizontally movable rotation shaft 4 is mounted on the third support rod 7, and the drive unit 3 is mounted on the end of the fourth support rod 8. One end of the fourth support rod 8 is rotatably connected to the third support rod 7, and the drive unit 3 is mounted on the other end.

[0052] As shown in FIG. 9, the seventh specific embodiment of the gravity compensation mechanism adapted to the head-mounted smart device of the present invention is as follows: The gravity compensation mechanism is adapted for a head-mounted smart device and includes a first support member, a second support member, a drive unit (3), and a horizontally movable rotation shaft (4).

[0053] The first support member is a back fixed rod 13, which is fixed to the body of the user 10 by a belt-like structure 15, and the second support member is an output swing arm 14, which is relatively movably connected to the back fixed rod 13 and cooperates with the back fixed rod 13 to provide a supporting force for the head-mounted smart device 9 to overcome gravity.

[0055] The horizontally movable rotation axis 4 is provided on the output swing arm 14, and when the head of the user 10 rotates horizontally, the output swing arm 14 rotates relative to the back fixed rod 13 in conjunction with the rotation of the head of the user 10.

[0056] By forming the output swing arm 14 into a fork-shaped structure or a substantially Y-shaped structure, the structural strength of the output swing arm 14 can be increased, and the head-mounted smart device 9 can be supported effectively.

[0057] An eighth specific embodiment of the gravity compensation mechanism adapted to the head-mounted smart device of the present invention is as follows: A gravity compensation mechanism adapted for a head-mounted smart device, comprising a first support member that can be fixed to the body of 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 being connected by a connecting member so as to be relatively movably connected to each other and cooperate with the movement of the head of the user (10).

The weight of the head-mounted smart device 9 is transmitted to the body of the user 10 sequentially via the towing rope 12, the second support rod 6 and the first support rod 1, thereby reducing or offsetting the weight that needs to be borne by the head of the user 10 and realizing gravity compensation for the head-mounted smart device 9.

[0060] When the user 10 needs to turn around, the second support member is rotated to the first support member, thereby changing the horizontal position of the head-mounted smart device 9.

[0061] When the user 10 needs to look up or down, he or she moves the towing rope 12 up or down, and the rotary motor detects the change in the towing rope 12 and winds or releases the towing rope, thereby realizing any change in the posture of the head-mounted smart device 9 and instantly compensating for the gravity of the head-mounted smart device 9.

[0062] Specific examples of head-mounted smart devices that use the gravity compensation mechanism of the present invention are as follows: A head-mounted smart device with gravity compensation effect includes a head-mounted smart device, a first support member that can be fixed to the body of a user 10 or an object around the user 10, and a second support member that can compensate for gravity of the head-mounted smart device, wherein the head-mounted smart device is connected to the second support member, and the first support member and the second support member are connected by a connecting member so as to be relatively movably connected to each other and cooperate with the movement of the head of the user 10.

[0063] The first support member is a first support rod 1, the upper end of which is connected to a second support member, and the lower end of which is provided with a belt-like structure that is tied to the body of the user 10, and the second support member is an L-shaped support rod 2 that can be placed around the head of the user 10, the lateral part of which is connected to a head-mounted smart device, and the connecting member is a universal joint with damping.

[0064] When in use, the first support rod 1 is fixed to the body of the user 10 by the belt-like structure, and the user 10 wears the head-mounted smart device. The weight of the head-mounted smart device is transmitted to the body of the user 10 via the second support rod 6 and the first support rod 1, thereby reducing or offsetting the weight that needs to be borne by the head of the user 10 and realizing gravity compensation for the head-mounted smart device 9.

[0065] When the user 10 needs to turn around, look up, or look down, the second support member is driven to overcome the resistance of the universal joint, causing the second support member to move correspondingly to the first support member, thereby realizing any change in the posture of the head-mounted smart device, which is easy to use and manufacture.

[0066] Finally, the above examples are used for illustration purposes only, rather than for limiting the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above examples, those skilled in the art will understand that amendments or equivalent replacements may still be made to the specific embodiments of the present invention, and any amendments or equivalent replacements that do not depart from the spirit and scope of the present invention should fall within the protection scope of the claims of the present invention.
