[0002] In order to meet people's needs to relieve physical fatigue, there are currently many forms of massagers on the market, including multi-point massagers that can achieve multi-point compound stimulation on the user's body. However, some existing multi-point massagers use complex mechanical structures, such as using multiple drivers to drive each impact massage head separately, or designing a complex transmission mechanism so that each impact massage head can move independently, which not only increases the manufacturing cost, but also is not conducive to the miniaturization of the overall volume of the massager. As shown in CN214550220U, the return of its massage head needs to be returned by an elastic member, which has a high manufacturing cost and is not conducive to the miniaturization of the overall volume of the massager.

[0029] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0030] like Figure 1-2 As shown, the embodiment of the utility model provides a multi-point alternating impact massage device, including an impact massage head 1, a mounting box 2, a motion shaft 3, a rotating shaft member 4, a cover plate 5 and a motor 6; wherein the impact massage head 1 has a plurality of impact massage heads, and the plurality of impact massage heads 1 alternately impact the user's body to achieve a massage effect; the mounting box 2 is hollow, and one end of the mounting box 2 is closed by installing a cover plate 5; a rotatable rotating shaft member 4 is installed in the middle of the mounting box 2, and a plurality of motion shafts 3 are installed around the rotating shaft member 4 in the mounting box 2, and the rotation axis of the rotating shaft member 4 is aligned with the rotation axis of the rotating shaft member 4. The axis line of the moving shaft 3 is parallel; a plurality of impact massage heads 1 inserted into the inside of the mounting box 2 are installed at the end of the mounting box 2 opposite to the cover plate 5, and the impact massage heads 1 are connected to the moving shaft 3 (that is, the impact massage heads 1 and the moving shaft 3 correspond one to one); the end of the rotating shaft 4 away from the impact massage head 1 is connected to the motor 6; the motor 6 drives the rotating shaft 4 to rotate, and the rotating shaft 4 cooperates with the moving shaft 3, and the rotation of the rotating shaft 4 drives each moving shaft 3 to reciprocate along the direction of its own axis line, thereby realizing that multiple heads impact the user's body in turn for massage.

[0031] Specifically, Figure 3As shown, in the embodiment of the utility model, a plurality of hollow insert tubes 21 are arranged around the inner wall of the installation box 2 in close contact with the inner wall, the axis of the insert tube 21 is parallel to the rotation axis of the rotating shaft 4, and corresponding through holes are provided on the bottom wall of the installation box 2 to be connected with the hollow channels of each insert tube 21; each insert tube 21 is provided with a slide groove 211 on one side facing the center of the installation box 2, and the slide groove 211 extends along the direction of the axis of the insert tube 21.

[0032] like Figure 4 As shown, the motion shaft 3 includes a shaft body 31, which can be inserted into the aforementioned inserting tube 21, and one end of the shaft body 31 has a blind hole 311, and one end of the aforementioned impact massage head 1 passes through the through hole of the bottom wall of the installation box 2 and is inserted into the blind hole 311 to achieve connection with the motion shaft 3; the side of the motion shaft 3 has a contact piece, and the contact piece includes a radially protruding mounting handle 32 arranged on the outer side of the shaft body 31, and further, the contact piece includes a follower 33 installed on the mounting handle 32, and the follower 33 can rotate around the mounting handle 32, and the follower 33 is preferably a bearing roller. When the shaft body 31 is inserted into the aforementioned inserting tube 21, the mounting handle 32 penetrates into the slide groove 211 to be lifted and lowered along the slide groove 211, retaining the axial linear freedom of the shaft body 31 while limiting its axial rotational freedom.

[0033] The rotating shaft 4 includes a connecting rod 41. Figure 5 In one embodiment shown, the rotating shaft 4 further includes a column 42 formed on the connecting rod 41; the column 42 is provided with a closed-loop limiting groove 421 extending along the circumference direction of the connecting rod 41, and the limiting groove 421 is inclined to the axis of the connecting rod 41. By designing the limiting groove 421 as a closed-loop groove, the connecting rod 41 can be driven to rotate in one direction to realize the reciprocating lifting and lowering of the plurality of moving shafts 3.

[0034] Figure 6 The assembly relationship between the impact massage head 1, the motion shaft 3 and the rotating shaft member 4 in this embodiment is demonstrated, and also the working principle of the utility model embodiment that can realize multi-head alternating massage is demonstrated: the motion shaft 3 is restricted by the insert cylinder 21, and has a linear degree of freedom along the direction of its own axis, and the impact massage head 1 is installed on the motion shaft 3; at the same time, since the follower 33 is embedded in the limiting groove 421, during the rotation of the connecting rod 41, the follower 33 is pushed by the column 42, so that the shaft body 31 performs reciprocating linear motion along the direction of its own axis; in the utility model embodiment, since a plurality of motion shafts 3 are installed around the rotating shaft member 4, and the limiting groove 421 is inclined to the axis of the connecting rod 41, each motion shaft 3 will be alternately pushed by the column 42, that is, a plurality of motion shafts 3 are alternately reciprocating linear motion along the direction of the rotation axis of the rotating shaft member 4 (the rotation axis of the rotating shaft member 4 is parallel to the axis of the motion shaft 3), thereby realizing the massage function.

[0035] In addition, the limit groove 421 can be designed as an open-loop spiral structure, and the motor 6 can be set to a cyclic forward and reverse driving form, that is, the limit groove 421 adopts a spiral groove with unconnected ends of the groove, so that the connecting rod 41 can drive several moving shafts 3 to reciprocate and rise and fall in the forward and reverse rotation, and the alternating movement effect of multiple moving shafts 3 can also be achieved. However, this forward and reverse rotation method is better suitable for low-speed rotation.

[0036] The multi-point alternating impact massage device provided by the utility model has a moving shaft arranged around a rotating shaft, and the axis of the moving shaft is parallel to the rotation axis of the rotating shaft, and the rotation of a single rotating shaft can drive multiple moving shafts to reciprocate. Firstly, compared with the existing massagers, the utility model greatly simplifies the structure, reduces the use of parts, and reduces the manufacturing cost; secondly, compared with the existing massagers, the volume is greatly reduced, making it more compact and portable, which better meets the current consumer demand for miniaturization and portability of products; finally, compared with the existing massagers, each impact massage head of the utility model is driven by the same rotating shaft, so the consistency of the movement of each impact massage head can be guaranteed, thereby improving the massage effect.

[0037] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
