The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] See also Figure 1-4As shown, the embodiment of the present application provides a massager, which includes a driving mechanism 1 and two massage combination mechanisms 2, wherein the driving mechanism 1 is connected to the two massage combination mechanisms 2 respectively, and each massage combination mechanism 2 includes a shoulder and neck massage mechanism 21 and a back massage mechanism 22; wherein the shoulder and neck massage mechanism 21 includes a shoulder and neck massage head 211, an eccentric wheel assembly 213 and a shoulder and neck transmission assembly 212, and the driving mechanism 1, the eccentric wheel assembly 213, the shoulder and neck transmission assembly 212 and the shoulder and neck massage head 211 are connected in sequence so that the shoulder and neck massage head 211 performs a spatial swing motion and enables The two shoulder and neck massage heads 211 can move closer to or farther away from each other while swinging in space; the back massage mechanism 22 includes a back massage head 221 and a back transmission assembly 222, one transmission end of the back transmission assembly 222 is connected to the eccentric wheel assembly 213, and the other transmission end of the back transmission assembly 222 is movably connected to the back massage head 221; the back massage head 221 is also movably connected to the shoulder and neck transmission assembly 212, so that the back massage head 221 can move toward or away from the corresponding shoulder and neck massage head 211 while following the shoulder and neck massage head 211 swinging in space.

[0034] The driving mechanism 1 is the power source of the massager. Exemplarily, the driving mechanism 1 may include a driver 11, which may be a motor, a hydraulic device or the like. The driving mechanism 1 is used to transmit motion, and the driving mechanism 1 is respectively connected to the two massage combination mechanisms 2. Therefore, it can be understood that the driving mechanism 1 has two power output ends, and the power output ends are used to output rotational force. The two driving ends are respectively connected to the two massage combination mechanisms 2 to transmit power to the two massage combination mechanisms 2.

[0035] Combination Figure 2 As shown, the two massage combination mechanisms 2 can be symmetrically arranged on both sides of the driving mechanism 1 to form a symmetrical left-right massage structure; of course, the two massage combination mechanisms 2 can also be designed asymmetrically on both sides of the driving mechanism 1, which can be designed according to needs.

[0036] Each massage combination mechanism 2 includes a shoulder and neck massage mechanism 21 and a back massage mechanism 22, wherein the shoulder and neck massage mechanism 21 is mainly used to massage the neck and shoulders of the human body. Therefore, it can be known that the shoulder and neck massage mechanism 21 must have a shoulder and neck massage head 211 that can abut against the neck or shoulders of the human body. The shoulder and neck massage head 211 can abut against the neck or shoulders of the human body respectively, or the shoulder and neck massage head 211 can abut against the neck or shoulders of the human body at the same time.

[0037] The driving mechanism 1, the eccentric wheel assembly 213, the shoulder and neck transmission assembly 212 and the shoulder and neck massage head 211 are connected in sequence, which means that the power output end (or driving end) of the driving mechanism 1 is connected to the eccentric wheel assembly 213 to drive the eccentric wheel assembly 213 to rotate eccentrically, and the eccentric wheel assembly 213 is further connected to the shoulder and neck transmission assembly 212, so that the shoulder and neck transmission assembly 212 can generate eccentric swing, and the eccentric swing can refer to the reciprocating swing of the shoulder and neck transmission assembly 212 in the swing plane perpendicular to the central axis of the eccentric wheel assembly 213, and can also refer to the reciprocating swing of the neck and shoulder transmission assembly in the swing plane perpendicular to the central axis of the eccentric wheel assembly 213 and the neck and shoulder transmission assembly deviating from the swing plane. The reciprocating swing is combined with spatial motion within the shoulder and neck transmission component 212, so, in this embodiment, it can be known that the eccentric swing of the shoulder and neck transmission component 212 is a spatial swinging motion; the shoulder and neck massage head 211 can be fixedly mounted on the shoulder and neck transmission component 212, so, it can be understood that the shoulder and neck massage head 211 can also perform spatial swinging motion; the shoulder and neck massage head 211 is a structure that directly abuts against the neck or shoulder of the human body, so, it can be known that the shoulder and neck massage head 211 can move to multiple positions in space, so that the shoulder and neck massage head 211 can form more contact positions with the neck and shoulders, increasing the massage area. In addition, the spatial swinging motion of the shoulder and neck massage head 211 can enhance the comfort of massage.

[0038] Exemplarily, the two massage combination mechanisms 2 are symmetrically arranged on both sides of the driving mechanism 1. Then, while the two shoulder and neck massage heads 211 are performing spatial swinging motion respectively, the two shoulder and neck massage heads 211 can form a swinging motion state of approaching or moving away from each other in the spacing direction, so that the two shoulder and neck massage heads 211 can form a clamping pressing pressure on the neck. Combined with the spatial swinging motion, the two shoulder and neck massage heads 211 can form a massage method that imitates human hands, thereby enhancing the comfort of massage.

[0039] The back massage head 221 can abut against a partial area of ​​the human back, so it can be known that the back massage head 221 can support the upper shoulder and neck massage mechanism 21. The back massage head 221 and the shoulder and neck massage head 211 both form abutment areas with the human body, so that the entire massager forms a larger support area with the human body, which is beneficial to improving the stability or stability of the massager during the working process.

[0040] When the massager is in use, the back massage head 221 is located below the shoulder and neck massage head 211, the shoulder and neck massage head 211 abuts against the neck or shoulder of the human body, and the back massage head 221 abuts against the back of the human body. The back massage head 221 forms a support at the bottom, so that the shoulder and neck massage mechanism 21 can be supported on the neck without relying on the shoulder to reduce the pressure on the shoulder.

[0041] The back massage head 221 is connected to the eccentric wheel assembly 213 through the back transmission assembly 222. The eccentric wheel assembly 213 may be provided with an eccentric shaft hole, the central axis of the eccentric shaft hole is the eccentric axis, and the eccentric axis refers to the actual rotation axis that deviates from the central axis of the geometric center of the eccentric wheel. The power output end of the driving mechanism 1 may be a driving shaft or a transmission shaft, and the power output end is inserted into the eccentric shaft hole so that the eccentric wheel assembly 213 rotates eccentrically; the eccentric wheel assembly 213 may have one or more eccentric wheels, and the back transmission assembly 222 and the shoulder and neck transmission assembly 212 may be connected to an eccentric wheel on the eccentric wheel assembly 213, or the back transmission assembly 222 and the shoulder and neck transmission assembly 212 may also be connected to different eccentric wheels on the eccentric wheel assembly 213.

[0042] The eccentric wheel assembly 213 rotates to drive the back transmission assembly 222 to move, so that the back massage head 221 connected to the back transmission assembly 222 performs spatial swinging motion; in addition, since the back massage head 221 is also movably connected to the shoulder and neck transmission assembly 212, the spatial swinging motion of the shoulder and neck transmission assembly 212 can also drive the back massage head 221 to perform a pendulum motion in a direction toward or away from the shoulder and neck massage head 211; when the two back massage heads 221 are moving, they can also form a movement form of approaching or moving away from each other, so as to achieve a clamping and kneading massage method for the back, achieving an effect of imitating human hand massage.

[0043] Therefore, when the massager is working as a whole, the driving mechanism 1 is started, so that the massage combination mechanisms 2 on both sides work together, and the movement transmission of the eccentric wheel assembly 213 and the shoulder and neck transmission assembly 212 enables each shoulder and neck massage head 211 to perform a spatial swinging motion, and the shoulder and neck massage heads 211 on both sides can form a movement form of approaching or moving away from each other during the movement process, so as to form a clamping and kneading massage method for the neck, thereby achieving an effect of imitating human hand massage; in addition, through the movement transmission process of the eccentric wheel assembly 213 and the back transmission assembly 222, the back massage head 221 can also perform a spatial swinging motion, and at the same time, the movement of the shoulder and neck transmission assembly 212 and the back massage head 221 Dynamic transmission enables the back massage head 221 to move toward or away from the shoulder and neck massage head 211. Therefore, it can be seen that during the clamping and kneading process of the shoulder and neck massage head 211, the back massage head 221 is in contact with the back on the one hand, playing a role of supporting together with the neck massage head, thereby improving the stability of the movement of the shoulder and neck massage mechanism 21; in addition, the back massage head 221 can also swing in space and swing up and down relative to the neck massage head, thereby also achieving the effects of clamping and massaging the back and kneading up and down. The combination of the shoulder and neck massage mechanism 21 and the back massage mechanism 22 can achieve the effect of kneading by imitating the thumb and the other four fingers of a human hand, thereby achieving the purpose of improving the comfort of massage.

[0044] In this embodiment, the massager is provided with a shoulder and neck massage mechanism 21 on the one hand, and the shoulder and neck massage head 211 is made to swing in space, thereby achieving a clamping and kneading massage of the shoulder and neck in a manner imitating human hands, thereby improving the massage comfort of the shoulder and neck position; in addition, while providing the shoulder and neck massage mechanism 21, a back massage mechanism 22 is also provided, and the back massage head 221 is in contact with the back, which is beneficial to enhancing the working stability of the entire massager; the back massage head 221 is movably connected with the back transmission component 222 and the shoulder and neck transmission component 212 at the same time, so that the back massage head 221 can swing in space and can also swing toward or away from the shoulder and neck massage head 211, thereby achieving a clamping and up and down kneading massage of the back in a manner imitating human hands, thereby further improving the massage comfort.

[0045] In one embodiment, referring to Figure 3 and Figure 4 As shown, the eccentric wheel assembly 213 includes a first eccentric wheel 2131 and a second eccentric wheel 2132 connected to the first eccentric wheel 2131. The eccentric axis of the first eccentric wheel 2131 is parallel to the eccentric axis of the second eccentric wheel 2132 and is staggered. The eccentric axis of the first eccentric wheel 2131 is set as the first eccentric axis 21311, and the eccentric axis of the second eccentric wheel 2132 is set as the second eccentric axis 21321. In other words, the first eccentric axis 21311 is parallel to the second eccentric axis 21321 and is staggered; the shoulder and neck transmission assembly 212 is connected to the first eccentric wheel 2131, and the back transmission assembly 222 is connected to the second eccentric wheel 2132; in addition, the first eccentric axis 21311 and the second eccentric axis 21321 can also be arranged at an angle with the output axis 122 of the driving mechanism 1, and the angle is the matching angle a described below.

[0047] For example, refer to Figure 3 and Figure 4 As shown, the eccentric wheel assembly 213 is an integrally formed structure, and the eccentric wheel assembly 213 includes a first eccentric wheel 2131 and a second eccentric wheel 2132. The diameter of the first eccentric wheel 2131 and the diameter of the second eccentric wheel 2132 can be the same or different, and the thickness of the two eccentric wheels (referring to the first eccentric wheel 2131 and the second eccentric wheel 2132) along the eccentric axis direction can be the same or different.

[0048] The first eccentric axis 21311 and the second eccentric axis 21321 are arranged in parallel, and the first eccentric axis 21311 and the second eccentric axis 21321 are staggered or spaced apart in a direction perpendicular to the eccentric axis, so that the first eccentric wheel 2131 and the second eccentric wheel 2132 form a staggered structure.

[0049] In addition, in this embodiment, referring to Figure 4 As shown, a mounting hole is provided on the eccentric wheel assembly 213, and the mounting hole is used to be connected and fixed with the transmission output shaft 121 (or power output shaft) of the driving mechanism 1. The transmission output shaft 121 or the power output shaft can be referred to as the output shaft, and the central axis of the output shaft of the driving mechanism 1 is set as the output axis 122; the central axis of the mounting hole is offset and misaligned with the central axis of the geometric center of the first eccentric wheel 2131 and the central axis of the geometric center of the second eccentric wheel 2132, so that after the transmission output shaft 121 is inserted into the mounting hole, the first eccentric wheel 2131 and the second eccentric wheel 2132 can rotate eccentrically, thereby making The shoulder and neck massage head 211 and the back massage head 221 perform telescopic reciprocating motion forward and backward; the central axis of the mounting hole (i.e., the output axis 122) is also respectively arranged at a matching angle a with the first eccentric axis 21311 and the second eccentric axis 21321, and the matching angle a ranges from 0° to 45°. The above arrangement enables the shoulder and neck transmission assembly 212 connected to the first eccentric wheel 2131 and the back transmission assembly 222 connected to the second eccentric wheel 2132 to perform spatial swinging motion, and the spatial swinging motion of the shoulder and neck transmission assembly 212 and the back transmission assembly 222 can perform an "O"-shaped circular motion in space.
