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 first connecting rod, and a hinge frame connected to the head cover body.

[0006] The drive mechanism is mounted on the upper end of the massage chair back frame, and the drive mechanism is arranged along the vertical direction of the massage chair back frame;

[0007] The first end of the hinge frame is hinged to the movable end of the drive mechanism via the first connecting rod, and the second end of the hinge frame is hinged to the first end of the massage chair back frame. The first end and the second end of the hinge frame are spaced apart from each other.

[0008] When the first end of the hinge frame rises and falls with the moving end of the drive mechanism, the hinge frame rotates around the first end of the massage chair back frame.

[0009] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0010] 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 first connecting rod, a hinge frame connected to the head cover body, a second connecting rod, and a third connecting rod.

[0011] The drive mechanism is installed at the upper end of the massage chair back frame, and the drive mechanism is arranged along the vertical direction of the massage chair back frame.

[0012] The first end of the hinge frame is hinged to the movable end of the drive mechanism via the first connecting rod, and the second end of the hinge frame is hinged to the first end of the massage chair back frame. The first end and the second end of the hinge frame are spaced apart from each other.

[0013] When the first end of the hinge frame rises and falls with the movable end of the drive mechanism, the hinge frame rotates relative to the upper end of the massage chair back frame.

[0014] The second end of the hinge frame is hinged to the first end of the massage chair back frame via the second connecting rod, and the third end of the hinge frame is hinged to the second end of the massage chair back frame via the third connecting rod.

[0015] The first end and the third end of the hinge frame are both located in the horizontal part of the hinge frame, and the second end of the hinge frame is located in the vertical part of the hinge frame.

[0016] The beneficial effects of this invention are as follows: the hinge frame is driven to rotate around the massage chair back frame by the drive mechanism and the first connecting rod, thereby achieving stable rotation of the head cover body. Due to the arrangement of the first connecting rod, the second connecting rod, and the third connecting rod, multi-point support is provided for the head cover body, reducing the torque required for the drive mechanism to rotate the head cover body and improving the safety and stability of the head cover body during rotation.

[0034] 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.

[0035] Please refer to Figures 1-10 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 first connecting rod, and a hinge frame connected to the head cover body.

[0036] The drive mechanism is installed at the upper end of the massage chair back frame, and the drive mechanism is set along the vertical direction of the massage chair back frame;

[0037] The first end of the hinge frame is hinged to the movable end of the drive mechanism via the first connecting rod, and the second end of the hinge frame is hinged to the first end of the massage chair back frame. The first end and the second end of the hinge frame are spaced apart from each other.

[0038] As the first end of the hinge frame rises and falls with the moving end of the drive mechanism, the hinge frame rotates around the first end of the massage chair back frame.

[0039] The working principle of this invention is as follows: the hinge frame is hinged to the drive mechanism through the first connecting rod, and the hinge frame is hinged to the massage chair back frame, providing support for the flipping of the hinge frame and dispersing the gravity of the head cover body and the hinge frame.

[0040] As can be seen from the above description, the beneficial effects of the present invention are as follows: the hinge frame is driven to rotate around the massage chair back frame by the drive mechanism and the first connecting rod, thereby achieving stable rotation of the head cover body. Due to the arrangement of the first connecting rod, multi-point support is provided for the head cover body, reducing the torque required for the drive mechanism to rotate the head cover body.

[0041] Furthermore, both the first and second ends of the hinge frame are located below the movable end of the drive mechanism.

[0042] As described above, the first end of the articulated frame is located below the movable end of the drive mechanism to expand the rotation range of the headgear body and the articulated frame, while the second end of the articulated frame is used to provide support for the articulated frame, so that when the drive mechanism moves, it drives the horizontal section of the articulated frame to rise or fall, thereby improving the reliability of the movement.

[0043] Furthermore, the first end of the hinge frame is located on the side of the drive mechanism closer to the massage chair back, and the second end of the hinge frame is located on the side of the drive mechanism away from the massage chair back.

[0044] As described above, the first and second ends of the articulated frame are located on both sides of the drive mechanism, forming two hinge points. This provides good support for the tilting of the articulated frame and improves the tilting reliability of the articulated frame and the headgear body.

[0045] Furthermore, the hinge frame includes a horizontal portion and a vertical portion that are perpendicular to each other, with the first end of the hinge frame located in the horizontal portion and the second end of the hinge frame located in the vertical portion near the horizontal portion.

[0046] As described above, the first end is located in the horizontal part and is used to provide driving force to the horizontal part of the articulated frame when the drive mechanism moves, while the second end is located in the vertical part near the horizontal part to serve as a flip support point for the articulated frame and improve the flip stability of the articulated frame and the flip hood.

[0047] Furthermore, one end of the first connecting rod is hinged to the hinge frame, and the other end of the first connecting rod is hinged to the drive mechanism.

[0048] As can be seen from the above description, the first connecting rod is designed to create a buffer space between the drive mechanism and the articulated frame, thereby reducing the torque requirements of the drive mechanism when the articulated frame flips.

[0049] 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 first connecting rod, a hinge frame connected to the head cover body, a second connecting rod, and a third connecting rod.

[0050] The drive mechanism is installed at the upper end of the massage chair back frame, and the drive mechanism is set along the vertical direction of the massage chair back frame.

[0051] The first end of the hinge frame is hinged to the movable end of the drive mechanism via the first connecting rod, and the second end of the hinge frame is hinged to the first end of the massage chair back frame. The first end and the second end of the hinge frame are spaced apart from each other.

[0052] When the first end of the hinge frame rises and falls with the moving end of the drive mechanism, the hinge frame rotates relative to the upper end of the massage chair back frame.

[0053] The second end of the hinge frame is hinged to the first end of the massage chair back frame via the second connecting rod, and the third end of the hinge frame is hinged to the second end of the massage chair back frame via the third connecting rod.

[0054] The first and third ends of the hinge frame are located in the horizontal part of the hinge frame, and the second end of the hinge frame is located in the vertical part of the hinge frame.

[0055] As described above, the hinge frame is driven to rotate around the massage chair back frame via a drive mechanism and a first connecting rod, achieving stable rotation of the head cover body. Due to the first connecting rod, multi-point support is provided for the head cover body, reducing the torque required for the drive mechanism to rotate the head cover body.

[0056] Furthermore, it also includes a first extension;

[0057] The first extension is mounted perpendicularly to the horizontal part of the hinge frame on the horizontal part of the hinge frame;

[0058] The first connecting rod is hinged to the first extension.

[0059] Furthermore, it also includes a second extension;

[0060] The second extension is mounted perpendicularly to the horizontal part of the hinge frame, and the second connecting rod is hinged to the second extension.

[0061] The first extension and the second extension are arranged sequentially along the direction that gradually moves away from the vertical part of the hinge frame.

[0062] Furthermore, the length of the first extension is greater than the length of the second extension.

[0063] As described above, the first and second extension members are designed to extend the lever arm length, providing ample clearance for the movement of the second and third connecting rods, and ensuring the rotational stability of the articulated frame and the headgear body.

[0064] Furthermore, when the vertical part of the hinge frame is parallel to the drive mechanism, the first end of the massage chair back frame and the second end of the hinge frame are located on both sides of the vertical part of the hinge frame.

[0065] As described above, the first and second ends of the massage chair backrest are located on both sides of the vertical part, providing ample space for the second connecting rod to move and avoid interference.

[0066] Furthermore, the second end of the hinge frame is located on the side of the drive mechanism away from the massage chair back, while the first end and the third end of the hinge frame are located on the side of the drive mechanism closer to the massage chair back.

[0067] As described above, the second and third ends of the articulated frame are located on both sides of the drive mechanism to form a lever arm of optimal length, ensuring that the drive mechanism can provide good driving force to the vertical and horizontal parts of the articulated frame and improve the stability of the headgear body.

[0068] Please refer to Figures 1-4 Embodiment 1 of the present invention is as follows:

[0069] A flip-up headrest includes a headrest body 2 mounted on the upper end of a massage chair backrest 1, a drive mechanism 3, a first connecting rod 4, and a hinge frame 5 connected to the headrest body 2. The drive mechanism 3 is mounted on the upper end of the massage chair backrest 1 and is arranged along the vertical direction of the massage chair backrest 1. The first end 51 of the hinge frame is hinged to the movable end of the drive mechanism 3 through the first connecting rod 4, and the second end 52 of the hinge frame is hinged to the first end of the massage chair backrest 1. The first end 51 and the second end of the hinge frame are spaced apart from each other. When the first end 51 of the hinge frame rises and falls with the movable end of the drive mechanism 3, the hinge frame 5 rotates around the first end of the massage chair backrest 1.

[0070] In this embodiment, both the first end 51 and the second end of the hinge frame are located below the movable end of the drive mechanism 3.

[0071] In this embodiment, the first end 51 of the hinge frame is located on the side of the drive mechanism 3 near the massage chair back frame 1, and the second end 52 of the hinge frame is located on the side of the drive mechanism 3 away from the massage chair back frame 1.

[0072] 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 is located on the horizontal portion 54, and the second end 52 of the hinge frame is located on the vertical portion 55 near the horizontal portion 54. The first connecting rod 4 forms a first angle α with the horizontal portion 54, and the first angle α is located on the side of the first connecting rod 4 near the vertical portion 55. As the hinge frame 5 moves from a fully raised state to a fully lowered state, the angle α gradually decreases, and the maximum value of the first angle α is less than 180°. Furthermore, the first end 51 of the hinge frame is hinged to the horizontal portion 54. To avoid the first connecting rod 4 being too long and to ensure that the drive mechanism 3 can apply a stable driving force to the hinge frame 5 through the first connecting rod 4, the distance from the first end 51 of the hinge frame to the vertical portion 55 is less than the distance of the first connecting rod 4.

[0073] In this embodiment, one end of the first connecting rod 4 is hinged to the hinge frame 5, and the other end of the first connecting rod 4 is hinged to the drive mechanism 3.

[0074] 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 is hinged to the slider 32 through the first connecting rod 4.

[0075] The working principle of this embodiment is as follows:

[0076] When the headgear body 2 and the hinge frame 5 are in the fully raised state, the angle α of the first included angle is at its maximum value. At this time, the slider 32 is at the upper end of the linear push rod 31. In order to make the headgear body 2 enter the fully lowered state, that is, to completely cover the human head inside the headgear body 2, the linear push rod 31 drives the slider 32 to move down. The headgear body 2 rotates around the second end 52 of the hinge frame and gradually sinks until the slider 32 moves to the lower end of the linear push rod 31 and stops. If the headgear body 2 is to enter the fully raised state, the slider 32 moves in the opposite direction.

[0077] Please refer to Figures 6-10 Embodiment two of the present invention is as follows:

[0078] A flip-up headrest includes a headrest body 2 mounted on the upper end of a massage chair backrest 1, a drive mechanism 3, a first connecting rod 4, a hinge frame 5 connected to the headrest body 2, a second connecting rod 6, and a third connecting rod 7. The drive mechanism 3 is mounted on the upper end of the massage chair backrest 1 and is arranged along the vertical direction of the massage chair backrest 1. The first end 51 of the hinge frame is hinged to the movable end of the drive mechanism 3 via the first connecting rod 4, and the second end 52 of the hinge frame is hinged to the first end of the massage chair backrest 1. The first end 51 of the hinge frame is connected to the hinge frame. The second ends 52 of the hinge frame are spaced apart from each other; when the first end 51 of the hinge frame rises and falls with the moving end of the drive mechanism 3, the hinge frame 5 rotates relative to the upper end of the massage chair back frame 1; the second end 52 of the hinge frame is hinged to the first end of the massage chair back frame 1 through the second connecting rod 6, and the third end 53 of the hinge frame is hinged to the second end of the massage chair back frame 1 through the third connecting rod 7; the first end 51 and the third end 53 of the hinge frame are both located in the horizontal part 54 of the hinge frame 5, and the second end 52 of the hinge frame is located in the vertical part 55 of the hinge frame 5. The first end of the massage chair back frame 1 is located on the extension rod 11 of the massage chair back frame 1. The four-bar linkage mechanism, consisting of the drive mechanism 3, the first connecting rod 4, the second connecting rod 6, and the third connecting rod 7, has multiple hinge points to drive the hinge frame 5 and the flip head cover to rotate stably relative to the upper end of the massage chair back frame 1. During this process, due to the length limitations of the first connecting rod 4 and the third connecting rod 7, the head cover body 2 rotates within a specified range, which can both achieve stable rotation and avoid collision with the human head.

[0079] In this embodiment, a first extension member 8 is also included; the first extension member 8 is mounted perpendicularly to the horizontal portion 54 of the hinge frame 5 on the horizontal portion 54 of the hinge frame 5; the first connecting rod 4 is hinged to the first extension member 8.

[0080] In this embodiment, a second extension member 9 is also included; the second extension member 9 is mounted perpendicularly to the horizontal portion 54 of the hinge frame 5 and is hinged to the second extension member 9; the first extension member 8 and the second extension member 9 are arranged sequentially along the direction gradually away from the vertical portion 55 of the hinge frame 5.

[0081] In this embodiment, the length of the first extension member 8 is greater than the length of the second extension member 9.

[0082] In this embodiment, when the vertical portion 55 of the hinge frame 5 is parallel to the drive mechanism 3, the first end of the massage chair back frame 1 and the second end 52 of the hinge frame are located on both sides of the vertical portion 55 of the hinge frame 5.

[0083] In this embodiment, the second end 52 of the hinge frame is located on the side of the drive mechanism 3 away from the massage chair back frame 1, while the first end 51 and the third end 53 of the hinge frame are located on the side of the drive mechanism 3 closer to the massage chair back frame 1. The first connecting rod 4 and the first extension 8 form a second included angle β, and the second included angle β is located on the side of the first connecting rod 4 closer to the vertical part 55. During the process of the hinge frame 5 moving from a fully raised state to a fully lowered state, the angle of the second included angle β gradually increases, and the angle of the second included angle β is between 40° and 130°. The third connecting rod 7 and the second extension 9 form a third included angle λ, and the third included angle λ is located on the side of the second extension 9 closer to the vertical part 55. During the process of the hinge frame 5 moving from a fully raised state to a fully lowered state, the angle of the third included angle λ gradually increases. The angle gradually increases, and the angle of the third included angle λ is greater than or equal to 60° and less than 90°. When the head cover body 2 is fully raised, the angle value of the third included angle λ is the smallest, and when the head cover body 2 is fully lowered, the angle value of the third included angle λ is the largest. The second connecting rod 6 and the extension rod 11 form a fourth included angle θ, and the fourth included angle θ is located on the side of the third connecting rod 7 away from the vertical part 55. During the process of the hinge frame 5 from the fully raised state to the fully lowered state, the angle of the fourth included angle θ gradually decreases, and the angle of the fourth included angle θ is greater than or equal to 60° and less than 170°.

[0084] To improve the stability of the head cover body 2 during rotation, a second connecting rod 6 and a third connecting rod 7 are respectively provided on both sides of the massage chair back frame 1 in the width direction.

[0085] The working principle of this embodiment is as follows:

[0086] When the headgear body 2 and the hinge frame 5 are in the fully raised state, the angle of the second included angle β is at least 115°, the angle of the third included angle λ is 60°, the angle of the fourth included angle θ is 160°, and the slider 32 is located at the upper end of the linear push rod 31.

[0087] When the head cover body 2 and the hinge frame 5 enter the sinking state, the slider 32 moves towards the lower end of the linear push rod 31 under the drive of the linear push rod 31. The hinge frame 5 rotates relative to the upper end of the massage chair back frame 1, and the horizontal part 54 of the hinge frame 5 gradually sinks under the combined action of the first connecting rod 4 and the third connecting rod 7, while the vertical part 55 of the hinge frame 5 gradually rises under the drive of the second connecting rod 6. Specifically, during the process of the horizontal section of the hinge frame 5 gradually sinking, the first connecting rod 4 rotates around the first extension 8 toward the side where the vertical part 55 is located, the second connecting rod 6 gradually rotates closer to the drive mechanism 3, and the end of the third connecting rod 7 away from the second extension 9 gradually rises and rotates.

[0088] It is worth noting that the terms "upper" and "lower" in this invention refer to... Figure 2 and Figure 7 The direction indicated by the middle arrow.

[0089] In summary, the present invention provides a flip-up headgear, in which one end of the hinge frame is hinged to the backrest of a massage chair, and a new lever arm is formed by the drive mechanism and the first connecting rod, reducing the torque required for the headgear body to flip. The drive mechanism, together with the first, second, and third connecting rods, forms a four-bar linkage mechanism, which uses multiple hinge points to control the hinge frame and the headgear body, reducing the torque required for the headgear to flip and improving the stability of the headgear body during the flipping process. The first, second, and third connecting rods limit the rotation range of the headgear body, so that a stable accommodating space is formed between the headgear body and the front side of the massage chair backrest, ensuring the safety of the human head.

[0090] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
