Description

Technical Field

[0001] The utility model relates to a flexible rack installation structure of a massage mechanism, belonging to the technical field of massage equipment. Background Art

[0002] Most cinema chairs are made up of four parts: seat, backrest, armrest and footrest. In general, the footrest and armrest are integrated into a firmly installed armrest frame. The structure is generally steel-wood structure or steel-plastic structure. Cinema chairs are usually used in auditoriums, theaters, meeting halls, lecture halls and other places, and should have a good sight line when holding meetings and watching performances.

[0003] Traditional cinema massage seats do not have massage functions. In order to enhance the user's massage experience, we have developed and designed flexible massage cushions that can be installed on traditional cinema seats.

[0004] Since the flexible massage cushion is required to bend its running track, i.e., the rack, according to the changes in the user's back posture when working, how to ensure that the driving gear in the running mechanism and the running track, i.e., the rack, maintain stable meshing is crucial to the comfort and stability of the product. This patent publicly applies for a stable and reliable flexible rack mounting structure that can be applied to the flexible massage cushion. Utility Model Content

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] See also Figure 1-4A flexible rack installation structure of a massage mechanism includes at least one flexible rack 10 and a walking mechanism 20 installed on the flexible rack 10. A driving gear 30 for driving the flexible rack 10 is arranged in the walking mechanism 20. When working, the motor built into the walking mechanism 20 is used as a power source. After the reduction transmission by the reduction gear group, the driving gear 30 is driven to rotate, thereby realizing the movement of the walking mechanism 20 on the flexible rack 10 for massage. In this embodiment, two parallel flexible racks 10 are used, and the upper and lower ends of the flexible racks 10 are connected to form a flexible rectangular frame. The flexible rectangular frame adapts to bending according to the changes in the user's back posture when working. In actual application, there is at least one flexible rack 10, and the remaining racks can also be replaced by flexible tracks of other structures.

[0023] The upper surface and / or lower surface of the flexible rack 10 is provided with a groove structure or a ridge structure, the groove structure can improve the flexibility of the flexible rack 10, and the ridge structure can increase the toughness of the flexible rack 10. The groove structure can be used when the base thickness of the flexible rack 10 is thicker, and the ridge structure can be used when it is thinner.

[0024] The walking mechanism 20 is provided with a transverse constraint structure 70, which abuts against the outer side of the flexible rack 10 so that the inner side thereof is kept in close mesh with the driving gear 30; specifically, a mounting groove is provided on the outer surface wall of the outer shell of the walking mechanism 20, and the mounting groove is an open step groove 40 formed on the outer surface wall of the outer shell of the walking mechanism 20, and a cover plate 50 is provided on the longitudinal open side of the step groove 40. In actual application, the semi-enclosed installation space formed by the step groove 40 and the cover plate 50 can also be replaced by a fully-enclosed installation space of a groove plus a cover plate;

[0025] A lateral constraint structure 70 is arranged on the laterally open side, and the lateral constraint structure 70 is a limiting boss or a vertical roller; compared with the limiting boss, the structure of the vertical roller is more conducive to reducing the resistance and wear caused by the relative movement of the structure; one lateral side of the step groove 40 is the driving gear 30 extending out of the outer shell of the walking mechanism 20, and the other lateral side of the step groove 40 is the lateral constraint structure 70, that is, the limiting boss or the vertical roller.

[0026] The lateral restraint structure abuts against the outer side of the flexible rack 10 to keep the inner side of the flexible rack 10 in close mesh with the driving gear 30, thereby ensuring that the rack and the movement running mechanism can be stably meshed and transmitted.

[0027] Example 2

[0028] On the basis of the structure of Example 1, since the gap between the cover plate 50 and the mounting groove of the walking mechanism 20 is determined by the installation tightness of the cover plate 50, in order to smooth the flexible rack 10 in the mounting groove so that it can mesh more smoothly, and at the same time prevent the drive gear 30 and the flexible rack 10 from being misaligned and failing. In this embodiment, a longitudinal constraint structure is also provided on the walking mechanism 20. The longitudinal constraint structure is a ridge 51 provided on the inner side of the cover plate 50 and a boss structure 60 provided on the surface of the step groove 40. The boss structure 60 is a fixed arc protrusion, an embedded mounted roller or a roller mounted roller. The boss structure 60 mainly plays a supporting role to reduce the friction contact surface between the flexible rack 10 and the mounting groove. The ridge 51 structure mainly eliminates the gap between the cover plate to ensure that the flexible rack 10 can be stably pressed.

[0029] The longitudinal constraint structure constrains the height position of the flexible rack 10 relative to the movement running mechanism from the upper and lower sides, that is, the upper and lower positions of the flexible rack 10 relative to the driving gear 30 are constrained, thereby avoiding meshing failure caused by upper and lower misalignment.
