Description

Technical Field

[0001] This invention relates to the field of massage equipment, and in particular to a rotating headgear. Background Technology

[0002] To enhance the privacy of massage chairs, the demand for headrest covers is increasing. Currently, most massage chair headrest covers are manually adjustable by flipping them, which is inconvenient. While electric direct-drive headrest covers require significant torque due to their weight, the limited space in a massage chair often doesn't allow for the torque necessary for stable headrest flipping. Therefore, electric direct-drive headrest covers offer compromised safety and stability. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a flip-up hood that improves the stability and safety of the hood when flipped.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A flip-up head cover includes a head cover body mounted on the upper end of a massage chair back frame, a drive mechanism, a guide member, and a hinge frame connected to the head cover body.

[0006] Both the guide and the drive mechanism are mounted on the upper end of the massage chair back frame, and the guide and the drive mechanism are arranged to cross each other.

[0007] The first end of the hinge frame is hinged to the movable end of the drive mechanism, and the second end of the hinge frame is slidably and rotatably connected to the guide member. The first end and the second end are spaced apart from each other.

[0008] When the first end of the articulated frame rises and falls with the moving end of the drive mechanism, the second end of the articulated frame slides and rotates relative to the guide member following the movement of the first end, causing the headgear body to rotate relative to the back frame.

[0009] The beneficial effects of the present invention are as follows: the guide member guides the articulated frame while serving as the rotation fulcrum of the articulated frame, thereby improving the stability of the headgear body when the articulated frame drives the headgear body to flip, reducing the torque required by the drive mechanism to drive the headgear body to flip, ensuring that the drive mechanism can stably and reliably control the headgear body to flip, and improving the safety and stability of the headgear body.

[0021] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figures 1-4 A flip-up head cover includes a head cover body mounted on the upper end of a massage chair back frame, a drive mechanism, a guide member, and a hinge frame connected to the head cover body.

[0023] Both the guide components and the drive mechanism are mounted on the upper end of the massage chair back frame, and the guide components and the drive mechanism are arranged in a crisscrossing manner.

[0024] The first end of the hinge frame is hinged to the movable end of the drive mechanism, and the second end of the hinge frame can slide and rotate along the guide member to be connected to the guide member. The first end and the second end are spaced apart from each other.

[0025] When the first end of the articulated frame rises and falls with the moving end of the drive mechanism, the second end of the articulated frame slides and rotates relative to the guide member following the movement of the first end, causing the headgear body to rotate relative to the back frame.

[0026] The working principle of this invention is as follows:

[0027] The guide component guides the articulated frame while also serving as a fulcrum for its rotation, providing support for the stability of the articulated frame under the drive mechanism.

[0028] As can be seen from the above description, the beneficial effects of the present invention are as follows: the guide member guides the articulated frame while serving as the rotation fulcrum of the articulated frame, thereby improving the stability of the articulated frame when it drives the headgear body to flip, reducing the torque required by the drive mechanism to drive the headgear body to flip, ensuring that the drive mechanism can stably and reliably control the headgear body to flip, and improving the safety and stability of the headgear body.

[0029] Furthermore, the drive mechanism is positioned close to the backrest, and the guide includes a sliding section that extends away from the massage chair backrest and the drive mechanism, such that when the head cover body rotates relative to the massage chair backrest, the second end rotates or slides within the sliding section.

[0030] As described above, the sliding section of the guide is arranged perpendicularly to or intersecting with the massage chair back frame and the drive mechanism, and the sliding section extends away from the massage chair back frame and the drive mechanism, so that when the head cover body rotates relative to the massage chair back frame, it provides clearance space for the hinge frame to flip, so that the hinge frame can flip stably.

[0031] Furthermore, the direction of movement of the drive mechanism is parallel to that of the massage chair backrest.

[0032] As described above, the direction of the drive mechanism is parallel to the backrest of the massage chair, which reduces the space occupied by the drive mechanism and provides the maximum driving force to the first end of the hinge frame.

[0033] Furthermore, a roller is installed at the second end of the hinge frame, and the roller is slidably embedded in the guide member.

[0034] As described above, the rollers improve the smoothness of the sliding of the articulated frame and the headgear body relative to the guide.

[0035] Furthermore, the hinge frame includes a horizontal part and a vertical part that are perpendicular to each other, with the first end of the hinge frame located at the horizontal part and the second end of the hinge frame located at the intersection of the horizontal part and the vertical part.

[0036] As described above, by taking the intersection of the horizontal and vertical parts as the second end of the hinge frame, the turning radius of the hinge frame is maximized, thereby maximizing the accommodation space between the head cover body and the upper end of the massage chair back frame.

[0037] Furthermore, the length of the horizontal section is greater than the length of the vertical section.

[0038] As described above, the length of the horizontal part is greater than the length of the vertical part, which maximizes the space between the head cover body and the upper end of the massage chair back frame, ensuring safety and improving user experience.

[0039] Furthermore, it also includes a first connector;

[0040] The first connector is mounted perpendicularly to the horizontal part on the side of the horizontal part away from the vertical part, and the first end of the hinge frame is located on the first connector.

[0041] Furthermore, it also includes a second connector;

[0042] The second connector is installed at one end of the horizontal part near the vertical part and is perpendicular to the vertical part. The second end of the hinge frame is located on the second connector.

[0043] As described above, the first and second connectors are designed to increase the rotation radius of the hood body and improve the smoothness of its rotation while ensuring stable rotation of the hood body.

[0044] Furthermore, the guide is located between the two ends of the drive mechanism.

[0045] As can be seen from the above description, the guide is located between the two ends of the drive mechanism, which can avoid motion interference.

[0046] Furthermore, the angle between the horizontal part of the hinge frame and the guide is 10° to 60°.

[0047] As described above, the angle between the horizontal part of the articulated frame and the guide component can achieve stable and smooth rotation of the headgear body within this angle range, ensuring the safety and stability of the headgear body.

[0048] Please refer to Figures 1-4 Embodiment 1 of the present invention is as follows:

[0049] A flip-up headgear includes a headgear body 2 mounted on the upper end of a massage chair backrest 1, a drive mechanism 3, a guide member 4, and a hinge frame 5 connected to the headgear body 2. The guide member 4 and the drive mechanism 3 are both mounted on the upper end of the massage chair backrest 1, and the guide member 4 and the drive mechanism 3 are arranged intersecting each other. The first end 51 of the hinge frame 5 is hinged to the movable end of the drive mechanism 3, and the second end 52 of the hinge frame 5 is slidably and rotatably connected to the guide member 4. The first end 51 and the second end 52 are spaced apart from each other. When the first end 51 of the hinge frame 5 rises and falls with the movable end of the drive mechanism 3, the second end 52 of the hinge frame 5 slides and rotates relative to the guide member 4 following the movement of the first end 51, so that the headgear body 2 rotates relative to the backrest.

[0050] In this embodiment, the drive mechanism 3 is positioned close to the massage chair backrest 1, and the guide member 4 includes a sliding section that extends away from the backrest and drive mechanism 3, such that when the headrest body 2 rotates relative to the backrest, the second end 52 rotates or slides within the sliding section. Preferably, the sliding direction of the second end 52 within the sliding section is perpendicular to the direction of movement of the drive mechanism 3.

[0051] In this embodiment, the direction of movement of the drive mechanism 3 is parallel to that of the massage chair back frame 1.

[0052] In this embodiment, the second end 52 of the hinge frame 5 is equipped with a roller 53, which is slidably embedded in the guide member 4.

[0053] In this embodiment, the hinge frame 5 includes a horizontal portion 54 and a vertical portion 55 that are perpendicular to each other. The first end 51 of the hinge frame 5 is located at the horizontal portion 54, and the second end 52 of the hinge frame 5 is located at the intersection of the horizontal portion 54 and the vertical portion 55. Preferably, the length of the horizontal portion 54 is greater than the length of the vertical portion 55.

[0054] In this embodiment, a first connector 6 is also included; the first connector 6 is mounted perpendicularly to the horizontal part 54 on the side of the horizontal part 54 away from the vertical part 55, and the first end 51 of the hinge frame 5 is located on the first connector 6.

[0055] In this embodiment, a second connecting member 7 is also included. The second connecting member 7 is mounted on the end of the horizontal portion 54 near the vertical portion 55 and is perpendicular to the vertical portion 55. The second end 52 of the hinge frame 5 is located on the second connecting member 7. Preferably, a roller 53 is mounted on the end of the second connecting member 7 near the vertical portion 55 to improve the stability of the headgear body 2 during rotation. Specifically, the roller 53 is rotatably connected to the second connecting member 7 via a pivot.

[0056] In this embodiment, the drive mechanism 3 includes a linear push rod 31 and a slider 32; the slider 32 is connected to the linear push rod 31 in a transmission manner, and the first end 51 of the hinge frame 5 is hinged to the slider 32.

[0057] In this embodiment, the guide member 4 is located between the two ends of the drive mechanism 3. Optionally, the included angle α between the horizontal part 54 of the hinge frame 5 and the guide member 4 is 10° to 60°. Specifically, when the hinge frame 5 is in a fully lowered state, the included angle α between the horizontal part 54 and the guide member 4 is 17°. In order to lower the head cover body 2 to the maximum extent, the included angle α can be reduced to 11°, 13°, 15° or 16°. When the hinge frame 5 is in a fully raised state, the included angle α between the horizontal part 54 and the guide member 4 is 51°. In order to give the head cover body 2 a larger unfolding angle, the included angle α when the hinge frame 5 is in a fully raised state can reach 55°, 56°, 57° or 58°.

[0058] The working principle of this embodiment is as follows:

[0059] When the head cover body 2 is in a fully lowered state, the linear push rod 31 pushes the slider 32 to move towards the upper end of the linear push rod 31. At the same time, the roller 53 rotates relative to the guide 4 and slides along the guide 4 away from the massage chair back frame 1 until the slider 32 moves to the end of the stroke of the linear push rod 31, at which point the head cover body 2 is in a fully raised state. Conversely, it pushes the slider 32 to move towards the lower end of the linear push rod 31.

[0060] In summary, the present invention provides a flip-up hood that, through the cooperation of rollers and guide members, forms a movable hinge point on the guide member for the hinge frame. While guiding the second end of the hinge frame, it also causes the second end of the hinge frame to gradually tilt along the side where the guide member is located. This reduces the torque requirements of the drive mechanism during the flip-up of the hood body, improves the stability of the hood body flip-up, and expands the unfolding angle of the hood body, reducing the probability of collision when the user sits down and improving safety.
