Description

Technical Field

[0001] The utility model relates to a damping connection structure of a massage chair light-shielding cover. Background Art

[0002] At present, some massage chairs on the market are equipped with light-shielding covers. The light-shielding covers can block the user's head and isolate the glaring lights, which can improve the use experience of the massage chair. For the current damping connection structure of the massage chair light-shielding cover, the light-shielding cover is usually rotatably arranged on the massage chair. It can be rotated according to the needs of the user to adjust the angle of the light-shielding cover, and it can also be retracted by rotation when the light-shielding cover is not in use.

[0003] After the light-shielding cover is rotated, it needs to be positioned. Currently, for the rotation positioning of the light-shielding cover on the market, it usually relies on a damper at the shaft connection. The damper usually includes two relatively rotatable support components and an adjusting nut arranged at the axial end position. There is a certain damping between the relative rotation of the two support components. By rotating the adjusting nut, the damping magnitude during the relative rotation of the two support components can be adjusted. During assembly, the two support components are respectively connected and fixed to the massage chair main body and the light-shielding cover, which can realize the rotational connection between the massage chair main body and the light-shielding cover and provide damping for their relative rotation, realizing the self-positioning of the light-shielding cover after rotating relative to the massage chair main body, and preventing the light-shielding cover from rotating automatically under the action of gravity and due to the vibration of the massage chair during operation.

[0004] Currently, the dampers adopted by the connection structures between the existing massage chair main body and the light-shielding cover are usually directly purchased from the market. When specifically applied, it is necessary to conduct targeted design for the connection structures among the massage chair main body, the light-shielding cover, and the damper. The dampers at the connection structures between the existing massage chair main body and the light-shielding cover are usually simply fixed together by screws, and the connection reliability is poor, which has higher requirements for the strength of plastic parts. In addition, the damper can be observed from the outside, and the aesthetics needs to be improved. Moreover, the components of the connection structure between the existing massage chair main body and the light-shielding cover need to be installed on the massage chair main body one by one in sequence before the overall connection structure can be formed, and the assembly process is relatively cumbersome. Additionally, due to the existence of connection holes among components such as the damper of the connection structure, it is necessary to align the holes for installation, and it is very easy to have problems such as misalignment of the hole positions and misinstallation during installation. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a damping connection structure of a massage chair light-shielding cover, which includes a damper that can position the rotation of the massage chair main body and the light-shielding cover, and has the advantages of compact structure, beautiful appearance, and strong connection reliability.

The damper is a rotary damper. The damper includes a first support member and a second support member. The first support member and the second support member are respectively connected and matched with the first base and the second base. A damped rotational connection and cooperation is formed between the first support member and the second support member. A rotational connection and cooperation is formed between the first base and the second base through the damper. One end of the first base includes a first plane and a first pit arranged on the first plane. The first support member of the damper is fixedly installed by being embedded in the first pit. One end of the second base includes a second plane and a second pit arranged on the second plane. The second support member of the damper is fixedly installed by being embedded in the second pit. The first plane of the first base and the second plane of the second base are arranged in parallel. Through holes for inserting adjusting nuts of the damper are also arranged in the first pit / second pit. The arrangement of the first pit and the second pit can improve the fixed installation effect on the first support member and the second support member, enable the first support member and the second support member to be embedded into the interiors of the first base and the second base, enable the adjusting nuts to be embedded into the interior of the first base / second base, make the overall connection structure more compact, the first plane and the second plane are arranged in parallel, and the gap at the rotational connection of the first base and the second base is more uniform and beautiful, and the presence of the damper is not easily visible from the outside of the gap, which can further improve the aesthetics.
