[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] See attached Figure 1 -Attached Figure 2 The present embodiment discloses a driving mechanism, which includes a motor 5, a mounting box 4, a transmission rod 6 and two driven components 7; a housing chamber 40 and a through hole 41 are provided in the mounting box 4, the motor 5 is installed in the housing chamber 40, and the output shaft of the motor 5 is placed outside the mounting box 4, and a driving wheel 50 is provided on the output shaft of the motor 5; the transmission rod 6 is rotatably installed in the through hole 41, and the axis of the transmission rod 6 is parallel to the axis of the output shaft of the motor 5; both ends of the transmission rod 6 pass through the through holes 41 and are respectively connected to the two driven components 7 for driving; a driven wheel 60 is fixed on the transmission rod 6, and the driven wheel 60 is meshed with the driving wheel 50.

[0026] Specifically, the motor 5 and the transmission rod 6 are integrated into the installation box 4, so that the structure of the drive mechanism is more compact and smaller in size, and can be used in massagers of various sizes, which is conducive to the promotion of the drive mechanism. In the present embodiment, the motor 5 is preferably a brushed motor, which is convenient for adjusting the speed of the motor 5; in order to facilitate the driving of the driven components 7 on both sides, in the present embodiment, both ends of the transmission rod 6 pass through the installation box 4, and the diameter of the driving wheel 50 is set to be smaller than the diameter of the driven wheel 60, and the transmission ratio of the two is 2 / 1, thereby increasing the torque of the transmission rod 6, so as to drive the driven components 7 on both sides to operate at the same time, and by amplifying the torque of the motor 5, the effect of the original multiple motors is achieved, so that the torque provided by the drive mechanism remains unchanged while the number of motors 5 is reduced. In general, the drive mechanism is miniaturized by integrating the motor 5 and the transmission rod 6 into the installation box 4, and realizes the simultaneous driving of multiple driven components 7 through gear transmission, which meets the needs of various massagers on the market and is conducive to promoting the drive mechanism for assembly and use on various massagers, so that the massagers using the drive mechanism can be smaller in size and lighter in weight, which is conducive to production and sale.

[0027] See attached Figure 2The driven assembly 7 includes a fixed seat 70 and a driven rod 71, and the driven rod 71 is rotatably mounted on the fixed seat 70; a driven bevel gear 72 is provided on the driven rod 71, and a transmission bevel gear 61 is provided at the end of the transmission rod 6, and the driven bevel gear 72 is meshed with the transmission bevel gear 61. Since the driven rod 71 and the transmission rod 6 are in a mutually perpendicular distribution relationship, the power is converted from the transmission rod 6 to the driven rod 71 in the form of meshing transmission of the two bevel gears, and then the massage assembly is driven to operate normally through the driven rod 71. In order to further increase the extrusion force of the massage assembly and improve the extrusion massage effect on the user, in this embodiment, the diameter of the transmission bevel gear 61 is smaller than the diameter of the driven bevel gear 72, and the transmission ratio is 2 / 1, so as to increase the torsion of the driven rod 71. In addition, the rotation speed of the driven rod 71 can be further reduced, so that when the driving mechanism is used in the massage instrument to drive the massage head to swing, the massage head will not swing rapidly, thereby avoiding discomfort to the human body caused by the rapid swing of the massage head.

[0028] As described above, the driving mechanism realizes primary torque amplification through the driving wheel 50 and the driven wheel 60, and realizes secondary torque amplification through the transmission bevel gear 61 and the driven bevel gear 72, thereby providing the massage component with four times the torque when the motor 5 is output. After the driving mechanism is applied to the massager, a single motor 5 can achieve the driving effect of multiple motors 5, and the overall weight of the massager can be lighter and the size can be smaller, which is convenient for users to use and carry.

[0029] It should also be noted that in order to avoid power loss during the transmission process, multiple bearings are installed on the transmission rod 6 and the driven rod 71 for support and limitation to improve the power transmission efficiency. In particular, the fixed seat 70 of the driven component 7 can be opened with two, and the two bearings on the driven rod 71 are connected to the side wall close to the two fixed seats 70, thereby realizing the axial limitation of the driven rod 71 and improving the stability of the overall structure.

[0030] In order to facilitate the installation of the motor 5 and the transmission rod 6, the installation box 4 includes two shells, each of which is provided with a connecting ear. The two shells are coaxially connected and fixed by the connecting ear. The shells are provided with grooves and through holes. After the two shells are connected, the grooves on the two shells form a accommodating cavity 40, and the through holes form a through hole 41. During actual installation, the motor 5 and the transmission rod 6 are wrapped by the two shells and fixed by screws penetrating the connecting ears on the two cylindrical shells.

[0031] The present application also provides a massager, comprising the above-mentioned driving mechanism.

[0032] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents.
