Description

Technical Field

[0001] This utility model relates to the field of massagers, and in particular to a telescopic swing mechanism structure. Background Technology

[0002] Existing massagers generally use a telescopic structure, such as a cam working in conjunction with a rotating device to achieve reciprocating oscillation. Their movements are relatively simple, so the massage points are mainly applied to localized areas, which affects the user experience.

[0003] Of course, there are other telescopic structures, such as Chinese Patent 202510059533.5, which uses a reciprocating lead screw structure. However, this structure is complex, and its massage is relatively simple, mainly acting on local areas. Utility Model Content

[0004] The main purpose of this invention is to propose a telescopic swing mechanism structure, which aims to improve the existing mechanism structure and achieve swinging and telescopic movement through a single drive structure. At the same time, its structure is simple and its layout is ingenious.

[0005] To achieve the above objectives, this utility model proposes a telescopic swing mechanism structure, comprising:

[0006] The driving device includes a rotating device, a rotating seat connected to the rotating device, a guide seat disposed on the outer wall of the rotating seat, and a telescopic seat slidably mounted on the guide seat.

[0007] The guide seat is fixedly mounted on the rotating device. The outer peripheral wall of the rotating seat is provided with a closed-loop drive groove that is not on the same plane. The drive groove is provided with a drive component.

[0008] The guide seat is vertically provided with a guide groove, and the drive component passes through the guide groove and is partially locked into the telescopic seat;

[0009] A telescopic shell, wherein a drive cavity is provided in the middle of the telescopic shell, and the telescopic shell is connected to a telescopic seat;

[0010] A swing shaft, the rear end of which swings on a guide seat, the middle part of which is connected to a telescopic shell, and the end of which extends out of the outer wall of the telescopic shell.

[0011] In the actual design, a hollow telescopic shell is used, and the swing shaft is installed inside the telescopic shell. Therefore, when the rotating device drives the rotating seat to rotate, the telescopic seat realizes the reciprocating movement of the telescopic seat through the relative movement of the driving groove and the guide groove by the driving component, which in turn drives the telescopic shell to reciprocate. The reciprocating swing is realized through the fulcrum of the swing shaft and the telescopic shell. The spatial layout realizes bidirectional massage, that is, massage of the swing shaft and the telescopic shell. Attached Figure Description

[0029] The guide seat 12 is fixedly mounted on the rotating device 10. The outer peripheral wall of the rotating seat 11 is provided with a closed-loop drive groove 21 (extending in a curved shape) that is not on the same plane. The drive groove 21 is provided with a drive component 2.

[0030] The guide seat 12 is vertically provided with a guide groove 22, and the drive member 2 passes through the guide groove 22 and is partially locked in the telescopic seat 13;

[0031] Telescopic shell 3, the telescopic shell 3 is provided with a drive cavity 31 in the middle, and the telescopic shell 3 is connected to the telescopic seat 13;

[0032] The swing shaft 4 has its rear end swinging on the guide seat 12, its middle part connected to the telescopic shell 3, and its end 8 extending out of the outer wall of the telescopic shell 3.

[0033] In the actual design, a hollow telescopic shell 3 is adopted, and the swing shaft 4 is installed inside the telescopic shell 3. Therefore, when the rotating device 10 drives the rotating seat 11 to rotate, the telescopic seat 13 achieves reciprocating movement of the telescopic seat 13 through the relative movement of the driving groove 21 and the guide groove 22 by the driving member 2, which in turn drives the telescopic shell 3 to reciprocate. The reciprocating swing is achieved through the fulcrum of the swing shaft 4 and the telescopic shell 3. The spatial layout realizes bidirectional massage, that is, massage of the swing shaft 4 and the telescopic shell 3.

[0034] Specifically, the telescopic seat 13 is provided with a through guide cavity 30, and the guide seat 12 is located in the guide cavity 30, thereby realizing reciprocating sliding and facilitating the positioning and installation of the rear end of the swing shaft 4.

[0035] In this embodiment of the invention, the driving component 2 is a positioning pin or a ball bearing.

[0036] The telescopic seat 13 is provided with a slot 14, and the ball bearing is partially engaged in the slot 14 and partially engaged in the drive groove 21, thereby realizing the reciprocating movement of the telescopic seat 13.

[0037] Specifically, the inner wall of the guide cavity 30 is hexagonal or circular (or other shapes), thereby achieving mutual fitting with the guide seat 12.

[0038] In this embodiment of the utility model, the top wall of the guide seat 12 is provided with an upwardly extending support arm 40, the upper end of which passes through the guide cavity 30.

[0039] The upper end of the support arm 40 is provided with a pivot part 41, the pivot part 41 is provided with a first rotating shaft 42, and the swing shaft 4 is provided with a strip groove 52 that cooperates with the first rotating shaft 42, thereby realizing the limiting of the rear end of the swing shaft 4.

[0040] Specifically, the support arm 40 is offset from the axis position. Through the misalignment, the swing shaft 4 can be set in a smaller drive cavity 31.

[0041] In this embodiment of the utility model, the driving cavity 31 is provided with a second rotating shaft 43, and the swing shaft 4 is provided with a shaft hole 51 that cooperates with the second rotating shaft 43, thereby driving it to swing back and forth with the shaft hole 51 as the fulcrum.

[0042] Specifically, the outer wall of the telescopic seat 13 is provided with an outwardly extending locking part 61, and the telescopic shell 3 is provided with a positioning groove 62 that cooperates with the locking part 61, thereby realizing the cooperation between the telescopic seat 13 and the telescopic shell 3.

[0043] In this embodiment of the utility model, the telescopic shell 3 is provided with a recessed clearance groove 7 at the position where the swing shaft 4 extends. Of course, the specific clearance groove 7 may not be recessed, but a recessed structure can allow the end of the swing shaft 4 to extend a greater length, thereby improving the massage effect.

[0044] Specifically, the end of the swing shaft 4 is widened from the end of the swing shaft to facilitate its fit with or installation and fixation with the massage layer structure.

[0045] The guide seat 12 can be fixedly installed on the telescopic motor or on the housing or other locations.

[0046] The telescopic shell consists of two half-shells.
