Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a double-shaft massager. Background Art

[0002] At present, the motion structures of common massage products are mostly divided into two categories. The first category uses a motor with an output shaft extending from one side, and the second category uses a motor with an output shaft extending from both sides. In actual applications, R&D personnel usually select different types of motion structures based on the space limitations of different appearances. Among them, the motion structure with a motor with an output shaft extending from both sides increases the dimension of the output shaft and combines transmission components such as eccentric shafts and connecting rods to achieve more diverse and refined massage movements, greatly improving the user experience. However, in the transmission module with a motor with an output shaft extending from both sides, the motor output shaft, eccentric shaft and connecting rod are usually connected in the form of a longitudinal connection, which leads to the problem of low internal space utilization of massage products.

[0003] In summary, how to improve the space utilization rate inside the double-axis massager is a technical problem that needs to be solved urgently in the field of massager technology. Utility Model Content

Among them, the motor output shaft A11 is longitudinally connected to the eccentric shaft A2, and the eccentric shaft A2 is longitudinally connected to the end portion A31 of the connecting rod. In the traditional massage motion structure, the motor output shaft A11, the eccentric shaft A2, and the end portion A31 of the connecting rod are longitudinally arranged and connected in sequence, resulting in waste of space inside the massage product and the problem of low space utilization rate.

[0033] The present utility model provides a dual-output shaft massager.

[0034] Please refer to Figure 2 , in the first embodiment of the present utility model, the dual-output shaft massager includes:

[0035] A transmission module 10 that is mirror-symmetrical;

[0036] The transmission module 10 includes a motor output shaft 101, an eccentric shaft 102, and an end portion 103 of the connecting rod. The eccentric shaft 102 is respectively transversely connected to the motor output shaft 101 and the end portion 103 of the connecting rod.

[0037] The dual-output shaft massager includes two mirror-symmetrical transmission modules 10. Any one of the transmission modules 10 includes a motor output shaft 101, an eccentric shaft 102, and an end portion 103 of the connecting rod. Among them, the eccentric shaft 102 is transversely arranged and connected to the motor output shaft 101, and the eccentric shaft 102 is transversely arranged and connected to the end portion 103 of the connecting rod.

[0038] Furthermore, referring to Figure 3 , the dual-output shaft massager further includes:

[0039] The connecting rod 20, the connecting rod 20 includes a piston 201 and the connecting rod end 103, with the horizontal line where the piston 201 is located as the central axis, and mirror-symmetrical transmission modules 10 are arranged on both sides of the central axis;

[0040] A connecting rod end 103 is provided at each end of the connecting rod 20, and the connecting rod 20 includes a piston 201. With the horizontal line where the piston 201 is located as the central axis, mirror-symmetrical transmission modules 10 are arranged on both sides of the central axis.

[0041] Thus, the present utility model provides a double-output shaft massager. The double-output shaft massager includes mirror-symmetrical transmission modules. The transmission module includes a motor output shaft, an eccentric shaft, and the end of the connecting rod, and the eccentric shaft is horizontally connected to the motor output shaft and the end of the connecting rod respectively. Thus, compared with the traditional way of longitudinally connecting the motor output shaft, the eccentric shaft, and the connecting rod, the present application improves the space utilization rate inside the massage product by horizontally connecting these three components.

[0042] Further, referring to Figure 4 , in the second embodiment of the present utility model, the eccentric shaft 102 is arranged on both sides of the motor output shaft 101 and is used to drive the connecting rod 20 to make a reciprocating motion based on the power transmitted by the motor output shaft 101.

[0043] The eccentric shaft 102 is arranged on both sides of the motor output shaft 101, and the eccentric shaft 102 can drive the connecting rod 20 to make a reciprocating motion based on the power transmitted by the motor output shaft 101.

[0044] In this embodiment, the connecting rod end 103 is provided with a groove matching the shape of the eccentric shaft 102, and the eccentric shaft 102 is embedded in the groove.

[0045] The connecting rod end 103 is provided with a groove matching the shape of the eccentric shaft 102, and the eccentric shaft 102 is cut into the groove for connecting the eccentric shaft 102 with the connecting rod end 103.

[0046] In this embodiment, the connecting rod end 103 includes a bearing 1031. The bearing 1031 is arranged on both sides of the eccentric shaft 102 and is used to fix and support the eccentric shaft 102;

[0047] The connecting rod end 103 is horizontally connected to the eccentric shaft 102 through the bearing 1031.

[0048] The connecting rod end 103 includes a bearing 1031. The bearing 1031 is arranged on the left and right sides of the eccentric shaft 102 and is used to fix and support the eccentric shaft 102. The connecting rod end 103 is horizontally connected to the eccentric shaft 102 through the bearing 1031.

[0049] In this embodiment, the double-output shaft massager further includes a motor 30 for providing a power source for the double-output shaft massager.

[0050] A motor 30 is provided in the double-output shaft massager, and the motor 30 provides a power source for the massaging action of the double-output shaft massager.

[0051] In this embodiment, the motor output shaft 101 is disposed at an end of the motor 30. The motor 30 is connected to the eccentric shaft 102 through the motor output shaft 101. The motor output shaft 101 is configured to drive the eccentric shaft 102 to perform a rotational motion when the motor 30 operates.

[0052] The motor output shaft 101 is disposed at an end of the motor 30, that is, a motor output shaft 101 is provided at each of the upper and lower ends of the motor 30. The motor 30 is connected to the eccentric shaft 102 through the motor output shaft 101. Since the motor 30 drives the motor output shaft 101 to move when it operates, the motor output shaft 101 can drive the eccentric shaft 102 to perform a rotational motion when the motor 30 operates.

[0053] In this embodiment, the bearing 1031 is further configured to convert the circumferential force generated by the rotational motion of the eccentric shaft 102 into a linear force for the eccentric shaft 102 to drive the connecting rod 20 to perform a reciprocating motion when performing a rotational motion.

[0054] It should be noted that the axis of the eccentric shaft 102 does not coincide with its geometric center but deviates by a certain distance, and this distance is called the eccentricity. This design enables a certain point (usually the eccentric point) on the outer circle of the eccentric shaft 102 to move along a circular trajectory when the eccentric shaft 102 rotates, and generates a circumferential force on the connecting rod 20 connected thereto. However, since the end 103 of the connecting rod is transversely connected to the eccentric shaft 102 through the bearing 1031, and the bearing 1031 is provided to convert the circumferential force generated by the rotational motion of the eccentric shaft 102 into a linear force for the eccentric shaft 102 to drive the connecting rod 20 to perform a reciprocating motion when performing a rotational motion.

[0055] In this embodiment, the eccentric shaft 102 is configured to drive the piston 201 to perform a reciprocating motion based on the power provided by the motor output shaft 101.

[0056] Since the connecting rod 20 includes the piston 201, when the eccentric shaft 102 performs a rotational motion based on the power provided by the motor output shaft 101 and drives the connecting rod 20 to perform a reciprocating motion under the action of the bearing 1031, the piston 201 on the connecting rod 20 is driven to perform a reciprocating motion accordingly.

[0057] In this embodiment, the double-output shaft massager further includes:

[0058] The silica gel sheath 40 is nested and connected with the piston 201, and is used to reciprocate based on the reciprocating motion of the piston 201 to generate a sucking feeling.

[0059] The double-output shaft massager further includes a silica gel sheath 40. The silica gel sheath 40 is nested and connected with the piston 201 on the connecting rod 20. The silica gel sheath 40 can reciprocate following the reciprocating motion of the piston 201, thereby generating a sucking feeling and achieving a massage effect.

[0060] In addition, it should be noted that the double-output shaft massager further includes a plastic housing 50. Among them, the plastic housing 50 is connected to the silica gel sheath 40 to jointly form the outer surface of the double-output shaft massager.

[0061] In this way, in the embodiment of the present application, the motor output shaft 101, the eccentric shaft 102 and the end of the connecting rod 103 are horizontally connected. And since the widths of the horizontally connected transmission components are less than or equal to the width of the motor 30, compared with the way of vertically connecting the transmission components, the horizontal connection method provided in the embodiment of the present application can improve the space utilization rate inside the double-output shaft massager, and shorten the longitudinal dimension of the massager, realizing the miniaturization of the product and meeting the user's requirements for the portability of the product.

[0062] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
