[0002] With the development of technology, in daily work, study or leisure and entertainment activities, people often experience discomfort in the muscles or bones of the body due to maintaining an improper posture for a long time, and in severe cases, even diseases will occur, thus affecting people's normal life. In order to alleviate the discomfort in the muscles or bones, various types of massage equipment have appeared on the market, such as neck massagers. The neck massager usually includes an elastic bracket and a clamping mechanism, wherein the elastic bracket is used to be worn on the neck, and the clamping mechanism is provided with two massage heads, and the two massage heads can be close to or away from each other, so as to pinch and massage the neck. However, when the massage heads apply a pinching operation to the neck, the neck will generate a reaction force, which will cause the two massage heads to have a tendency to slide away from the back of the neck, resulting in the massage heads being unable to stably pinch the neck.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. 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.

[0043] Please refer to Figures 1 to 3The present application provides a massage device 100, which can also be referred to as a massager, massage equipment, etc. The massage device 100 is used to massage a part to be massaged, which can be, but not limited to, the neck, legs, arms, etc. Accordingly, the massage device 100 can be, but not limited to, a neck massager, a leg massager, an arm massager, etc. The present application only takes the human neck as an example of the part to be massaged.

[0044] The massage device 100 includes an elastic support 10 and a clamping mechanism 20. The following is a detailed description with reference to the accompanying drawings.

[0045] Among them, the elastic bracket 10 is used to be worn on the neck of the user. The elastic bracket 10 includes a first elastic arm 11, a second elastic arm 12, and an intermediate bracket 13. The first elastic arm 11 and the second elastic arm 12 are arranged opposite to each other and are respectively connected to the opposite ends of the intermediate bracket 13, that is, the first elastic arm 11, the intermediate bracket 13, and the second elastic arm 12 are connected in sequence and the first elastic arm 11 and the second elastic arm 12 are opposite to each other. The end of the first elastic arm 11 and the second elastic arm 12 away from the intermediate bracket 13 is the abutment end 14. The first elastic arm 11, the intermediate bracket 13 and the second elastic arm 12 are jointly surrounded to form a wearing space X1.

[0046] The elastic bracket 10 has a certain elasticity. The elasticity referred to here means that when an external force acts on the first elastic arm 11 or the second elastic arm 12 so that the first elastic arm 11 and the second elastic arm 12 move away from each other, the first elastic arm 11 and the second elastic arm 12 have a tendency to move closer to each other. When the external force is removed, the first elastic arm 11 and the second elastic arm 12 can automatically move closer to each other. It can be understood that the elastic property of the elastic bracket 10 can make the massage device 100 more stably worn on the neck and not easy to fall off. The first elastic arm 11, the middle bracket 13, and the second elastic arm 12 of the elastic bracket 10 can be an integrated structure or a split structure, which is not limited here.

[0047] When the massage device 100 is in a non-use state, the abutting end 14 of the first elastic arm 11 and the abutting end 14 of the second elastic arm 12 may contact each other or be spaced apart. When the massage device 100 is in a use state, the abutting end 14 of the first elastic arm 11 and the abutting end 14 of the second elastic arm 12 may contact each other or be spaced apart. The use state refers to the state of the massage device 100 when it is worn on the human body, and correspondingly, the non-use state refers to the state of the massage device 100 when it is not worn on the human body.

[0048] Among them, the pinching mechanism 20 is used to massage the user's neck. The pinching mechanism 20 is arranged in the wearing space X1. The pinching mechanism 20 includes a shell 21, an airbag 22, a first massage head 23 and a second massage head 24. The shell 21 is mounted on the intermediate bracket 13. The first massage head 23 and the second massage head 24 are both movably connected to the shell 21. The airbag 22 is arranged in the shell 21. The airbag 22 will expand when inflated and will shrink when deflated. The airbag 22 can expand or shrink to enable the first massage head 23 and the second massage head 24 to move closer to or farther from each other to perform pinching massage on the massaged part. When the airbag 22 expands, the first massage head 23 and the second massage head 24 move closer to each other to pinch the massaged part. When the airbag 22 shrinks, the first massage head 23 and the second massage head 24 move away from each other. That is, the first massage head 23 and the second massage head 24 can move toward or away from each other by the expansion or contraction of the airbag 22, and a massage effect is formed when the moving first massage head 23 and the second massage head 24 act on the human body. When the airbag 22 expands or contracts cyclically, the first massage head 23 and the second massage head 24 can form a reciprocating motion, thereby obtaining a continuous massage effect.

[0049] When the first massage head 23 and the second massage head 24 are acted upon by the part to be massaged and move in the first preset direction Y1, the abutting end 14 is configured to abut the part to be massaged, and pull the intermediate bracket 13 through the first elastic arm 11 and the second elastic arm 12, so that the intermediate bracket 13 drives the clamping mechanism 20 to move in the second preset direction Y2. The first preset direction Y1 and the second preset direction Y2 are opposite directions to each other. That is, during the process of the first massage head 23 and the second massage head 24 massaging the part to be massaged, the first massage head 23 and the second massage head 24 will be acted upon by the part to be massaged, so that the entire massage device 100 moves in the first preset direction Y1. When the massage device 100 moves along the first preset direction Y1, the part to be massaged will abut against the abutting end 14 of the elastic bracket 10, and the abutting end 14 will transmit the abutting effect to the intermediate bracket 13, and the intermediate bracket 13 will then push the clamping mechanism 20 to move in the second preset direction Y2 opposite to the first preset direction Y1, thereby preventing the massage device 100 from moving in the first preset direction Y1.

[0050] Please refer to further Figure 4 It should be noted that Figure 4The massage device 100 shown hides some structural lines and parts to facilitate the understanding of the drawings. The massage part to be massaged is the neck for exemplary description: when the massage device 100 is worn on the neck, the first elastic arm 11, the middle bracket 13 and the second elastic arm 12 surround the neck. Among them, the middle bracket 13 is located at the back of the neck, the first elastic arm 11 and the second elastic arm 12 face the left and right sides of the neck respectively, the abutting end 14 of the first elastic arm 11 is located in front of the neck or the left front, the abutting end 14 of the second elastic arm 12 is located in front of the neck or the right front, and the distance between the abutting end 14 of the first elastic arm 11 and the abutting end 14 of the second elastic arm 12 is less than the radial dimension of the left and right sides of the neck, so that the massage device 100 can be stably worn on the neck. Among them, the back of the neck refers to the neck position away from the human face (or the neck position close to the back of the human body), and the front of the neck refers to the neck position away from the back of the human head (or the neck position close to the chest of the human body). Furthermore, the first massage head 23 and the second massage head 24 are respectively located on the left and right sides of the neck to cyclically apply pinching massage actions to the left and right sides of the neck. Since the neck will generate an oblique first force F1 on the first massage head 23 and the second massage head 24 respectively when the first massage head 23 and the second massage head 24 apply pinching actions to the neck, the first force F1 can be decomposed into a first component force F11 and a second component force F12, wherein the direction of the first component force F11 is parallel to the first preset direction Y1, and the direction of the second component force F12 is parallel to the relative direction of the first massage head 23 and the second massage head 24. The first resultant force Fh1 from the neck received by the pinching mechanism 20 in the first preset direction Y1 is twice the first component force F11, that is, Fh1=2*F11. It is understandable that the first combined force Fh1 will cause the first massage head 23 and the second massage head 24 to have a tendency to slide away from the back of the neck, that is, the massage device 100 will have a tendency to move from the front of the neck to the back of the neck (hereinafter referred to as backward movement), which may further cause the first massage head 23 and the second massage head 24 to be separated from the left and right sides of the neck and fail to continuously and stably massage the neck. In addition, in the related art, the first massage head 23 and the second massage head 24 are driven by a motor as a power source, and multiple transmission components need to be set between the motor and the two massage heads, which results in a larger weight of the clamping mechanism 20, thereby further increasing the backward movement tendency of the massage device 100.

[0051] In the present application, the first massage head 23 and the second massage head 24 are driven by the airbag 22. Compared with the motor drive, the weight of the clamping mechanism 20 is reduced, which can weaken the backward movement tendency of the massage device 100. In addition, when the first massage head 23 and the second massage head 24 move backward along the neck, the first elastic arm 11 and the second elastic arm 12 will also move backward. Since the distance between the abutting end 14 of the first elastic arm 11 and the abutting end 14 of the second elastic arm 12 is smaller than the size of the neck, during the backward movement, the neck will generate an oblique second force F2 on the abutting end 14 of the first elastic arm 11 and the abutting end 14 of the second elastic arm 12. The second force F2 can be decomposed into a third component F21 and a fourth component F22, wherein the direction of the third component F21 is parallel to the second preset direction Y2, and the direction of the fourth component F22 is parallel to the relative direction of the first elastic arm 11 and the second elastic arm 12. It is understandable that the third force component F21 received by the abutting end 14 of the first elastic arm 11 will be transmitted to the intermediate bracket 13 through the first elastic arm 11, and the third force component F21 received by the abutting end 14 of the second elastic arm 12 will be transmitted to the intermediate bracket 13 through the second elastic arm 12, so that the second resultant force Fh2 received by the intermediate bracket 13 from the abutting end 14 in the second preset direction Y2 is twice the third force component F21, that is, Fh2 = 2*F21. It is understandable that the second resultant force Fh2 received by the intermediate bracket 13 will be transmitted to the clamping mechanism 20, so that the clamping mechanism 20 has a tendency to move from the back of the neck to the front of the neck, so that the above-mentioned backward movement tendency can be prevented or weakened. In other words, the pinching mechanism 20 will eventually be subjected to the first combined force Fh1 and the second combined force Fh2, and the second combined force Fh2 will offset at least part of the first combined force Fh1. In this way, the pinching mechanism 20 can be prevented from moving backward or weakened, thereby ensuring as much as possible that the first massage head 23 and the second massage head 24 can stably perform pinching massage on the neck.

[0052] In summary, the massage device 100 provided in the present application is provided with an elastic bracket 10 and a clamping mechanism 20, wherein the elastic bracket 10 is used to be worn on the user's part to be massaged, and the clamping mechanism 20 is used to massage the user's part to be massaged. When the first massage head 23 and the second massage head 24 of the clamping mechanism 20 are acted upon by the part to be massaged and move along the first preset direction Y1, the abutting end 14 of the elastic bracket 10 can abut against the part to be massaged, and transmit the effect of the part to be massaged to the middle bracket 13 through the first elastic arm 11 and the second elastic arm 12, so that the middle bracket 13 pushes the clamping mechanism 20 along the second preset direction Y2 opposite to the first preset direction Y1, so that the movement of the clamping mechanism 20 along the first preset direction Y1 can be prevented or weakened, so that the first massage head 23 and the second massage head 24 can stably perform a clamping massage on the part to be massaged. In addition, the first massage head 23 and the second massage head 24 are driven by the airbag 22. Compared with the use of motor drive, the weight of the clamping mechanism 20 driven by the airbag 22 is reduced, which can also weaken the tendency of the massage device 100 to move in the first preset direction Y1, and can also reduce the pressure of the clamping mechanism 20 on the massage area.

[0053] Please refer to Figure 1 The massage device 100 further includes an air control component 30, which includes an air pump 31 and an air inlet pipe 32. The air pump 31 is used to inflate the airbag 22. The air pump 31 is disposed at the abutting end 14 of the first elastic arm 11 or the abutting end 14 of the second elastic arm 12. The air inlet pipe 32 is connected between the air pump 31 and the airbag 22 to communicate with the air pump 31 and the airbag 22. It is understandable that if the air pump 31 is installed on the intermediate bracket 13, the overall weight of the intermediate bracket 13 will increase, thereby exerting a stronger pressure on the back neck, and it is not conducive for the intermediate bracket 13 to drive the clamping mechanism 20 to approach the abutting end 14 through the deformation band. In this embodiment, since the air pump 31 is disposed at the abutting end 14, the overall mass of the intermediate bracket 13 is reduced, so that the pressure of the intermediate bracket 13 on the back neck can be reduced, and it is conducive to the intermediate bracket 13 to push the clamping mechanism 20.

[0054] Please refer to Figure 4, the extension direction of the shell 21 is the relative direction of the first elastic arm 11 and the second elastic arm 12. One end of the shell 21 extends and abuts the connection between the intermediate bracket 13 and the first elastic arm 11 to form a first fulcrum Z1. The intermediate bracket 13 and the first elastic arm 11 form a lever based on the first fulcrum Z1. The other end of the shell 21 extends and abuts the connection between the intermediate bracket 13 and the second elastic arm 12 to form a second fulcrum Z2. The intermediate bracket 13 and the second elastic arm 12 form a lever based on the second fulcrum Z2. When the first massage head 23 and the second massage head 24 are close to each other to pinch and massage the massaged area, the first elastic arm 11 and the second elastic arm 12 are configured to open outward based on the first fulcrum Z1 and the second fulcrum Z2, so that the intermediate bracket 13 is deformed and drives the pinching mechanism 20 to move in the second preset direction Y2.

[0055] In this embodiment, the two opposite ends of the shell 21 extend to the connection between the intermediate bracket 13 and the first elastic arm 11 and to the connection between the intermediate bracket 13 and the second elastic arm 12, respectively, which is conducive to increasing the lateral length of the shell 21 (the size of the shell 21 in the extension direction), so that a larger airbag 22 can be placed in the shell 21, which can ensure that the airbag 22 has a larger driving force, thereby increasing the massage strength of the first massage head 23 and the second massage head 24, and achieving strong pinching. At the same time, through the abutment of the shell 21, the intermediate bracket 13 and the first elastic arm 11 form a lever based on the first fulcrum Z1, and the intermediate bracket 13 and the second elastic arm 12 form a lever based on the second fulcrum Z2, so that when the first elastic arm 11 and the second elastic arm 12 are extended, the intermediate bracket 13 can be better moved toward the abutting end 14, so that the first massage head 23 and the second massage head 24 are not easy to move backward relative to the neck.

[0056] by Figure 4Take an example to illustrate: It can be understood that under the action of the fourth component force F22, the first elastic arm 11 will be elastically deformed and move away from the second elastic arm 12, and the second elastic arm 12 will also be elastically deformed and move away from the first elastic arm 11, that is, the first elastic arm 11 and the second elastic arm 12 will move away from each other and open. Since the intermediate bracket 13 and the first elastic arm 11 form a lever based on the first fulcrum Z1, when the first elastic arm 11 is elastically deformed and moves away from the second elastic arm 12, the intermediate bracket 13 will apply a third force F3 to the clamping mechanism 20. Similarly, the intermediate bracket 13 and the second elastic arm 12 form a lever based on the second fulcrum Z2. Therefore, when the second elastic arm 12 is elastically deformed and moves away from the first elastic arm 11, the intermediate bracket 13 will apply a fourth force F4 to the clamping mechanism 20. The third force F3 and the fourth force F4 are superimposed on the clamping mechanism 20 to form a third combined force Fh3. At least part of the component of the third combined force Fh3 is directed toward the second preset direction Y2, causing the intermediate bracket 13 to deform toward the second preset direction Y2. Therefore, the third combined force Fh3 will offset at least part of the first combined force Fh1. In this way, the backward movement of the clamping mechanism 20 can be weakened, thereby ensuring as much as possible that the first massage head 23 and the second massage head 24 can stably perform pinching massage on the neck.

[0057] Please refer to Figure 5 The intermediate bracket 13 includes a bracket body 133, a first abutting protrusion 131 and a second abutting protrusion 132. The opposite ends of the bracket body 133 are respectively connected to the first elastic arm 11 and the second elastic arm 12. The first abutting protrusion 131 and the second abutting protrusion 132 are connected to the intermediate bracket 13 and are arranged at intervals along the extension direction of the intermediate bracket 13. The first abutting protrusion 131 and the second abutting protrusion 132 are convexly arranged on the side of the bracket body 133 facing the shell 21, that is, the first abutting protrusion 131 and the second abutting protrusion 132 are both convex structures and both protrude toward the shell 21. The first abutting protrusion 131 and the second abutting protrusion 132 are fixedly connected to the shell 21 to realize the installation of the clamping mechanism 20 on the intermediate bracket 13. The connection method of the first abutting protrusion 131, the second abutting protrusion 132 and the shell 21 can be, but is not limited to, welding, bonding or connection through screws (such as bolts). It is understandable that the first supporting protrusion 131 and the second supporting protrusion 132 adopt a convex structure, which can prevent the strength of the intermediate bracket 13 from being weakened, so that the intermediate bracket 13 can always stably support the clamping mechanism 20.

[0058] Further, the first abutting protrusion 131 is closer to the middle part of the intermediate bracket 13 relative to the first fulcrum Z1. The second abutting protrusion 132 is closer to the middle part of the intermediate bracket 13 relative to the second fulcrum Z2. In other words, the middle position of the bracket body 133 in the extension direction is closer to the first abutting protrusion 131 and the second abutting protrusion 132. When the first elastic arm 11 and the second elastic arm 12 are opened outward, the first abutting protrusion 131 and the second abutting protrusion 132 push the clamping mechanism 20 to move in the second preset direction Y2, thereby eliminating at least part of the backward movement of the massage device 100. In this embodiment, the middle position of the bracket body 133 in the extension direction is closer to the first abutting protrusion 131 and the second abutting protrusion 132. Such a configuration can ensure that the first elastic arm 11 and the second elastic arm 12 can smoothly pry the intermediate bracket 13 through the lever structure when they are opened outward, so that the intermediate bracket 13 pushes the clamping mechanism 20 toward the abutting end 14.

[0059] Please refer to Figure 4 and Figure 5 , a cavity X2 is formed between the bracket body 133 of the intermediate bracket 13 and the shell 21, and the cavity X2 is located between the first abutting protrusion 131 and the second abutting protrusion 132. That is to say, at least part of the bracket body 133 is spaced apart from the shell 21 to form a spacing space, and the spacing space constitutes the above-mentioned cavity X2. For example, the shell 21 is provided with a recessed structure recessed toward the abutting end 14, and the bracket body 133 is covered at the opening of the recessed structure, and a cavity X2 is formed between the recessed structure and the bracket body 133. In this embodiment, by providing the cavity X2, the intermediate bracket 13 can be facilitated to bend and deform. When the intermediate bracket 13 is bent and deformed, the two abutting protrusions will generate a larger resistance force, thereby effectively reducing the backward displacement of the massage device 100 and ensuring that the first massage head 23 and the second massage head 24 clamp the neck.

[0060] Please refer to Figure 6 and Figure 7 The pinching mechanism 20 also includes a linkage assembly 25. The shell 21 has a housing cavity X4. The airbag 22 and the linkage assembly 25 are both arranged in the housing cavity X4. When the airbag 22 expands or contracts, the linkage assembly 25 can move in the housing cavity X4, so that the first massage head 23 and the second massage head 24 can be close to or away from each other, wherein the linkage assembly 25 can play a role in transmitting power, which can transmit the power from the expansion of the airbag 22 to the first massage head 23 and the second massage head 24, so that the first massage head 23 and the second massage head 24 can perform a pinching massage on the neck. The two ends of the shell 21 in the extension direction protrude toward the intermediate bracket 13 to abut against the intermediate bracket 13 and form an active cavity X3. The active cavity X3 is connected to the housing cavity X4 so that the linkage assembly 25 can move in the active cavity X3.

[0061] Specifically, the shell 21 can be divided into a first convex section A1, a main body section A2, and a second convex section A3. The first convex section A1 and the second convex section A3 are respectively connected to the opposite ends of the main body section A2, that is, the arrangement direction of the first convex section A1, the main body section A2, and the second convex section A3 is the extension direction of the shell 21. Among them, the main body section A2 has a receiving cavity X4, which is used to receive the airbag 22 and at least part of the linkage assembly 25, so that the airbag 22 and the linkage assembly 25 can move in the receiving cavity X4. The first convex section A1 and the second convex section A3 both have an active cavity X3, and the two active cavities X3 are connected to the receiving cavity X4. The active cavity X3 is used to receive at least part of the linkage assembly 25, so that at least part of the linkage assembly 25 can move in the active cavity X3. In addition, the first convex section A1 abuts against the connection between the intermediate bracket 13 and the first elastic arm 11 to form the above-mentioned first fulcrum Z1. The second outwardly protruding section A3 abuts against the connection between the intermediate bracket 13 and the second elastic arm 12 to form the second fulcrum Z2 mentioned above.

[0062] In this embodiment, by protruding the shell 21 toward the intermediate bracket 13 (first protruding section A1, second protruding section A3), the protrusion can form a fulcrum with the intermediate bracket 13, which is beneficial for the intermediate bracket 13 to push back the clamping mechanism 20 when deformed, making it difficult for it to move backward, and the shell 21 protrudes to form an active cavity X3, which can provide a larger activity space for the linkage component 25.

[0063] Please refer to Figure 6 The shell 21 includes a resisting shell 211 and a supporting shell 212 which are jointly arranged to form a containing cavity X4. The resisting shell 211 is connected to the intermediate bracket 13. The supporting shell 212 is located on the side of the resisting shell 211 which is away from the intermediate bracket 13. The opposite sides of the airbag 22 are respectively connected to the supporting shell 212 and the linkage assembly 25, so that the linkage assembly 25 can move in the containing cavity X4 when expanding or contracting. An air receiving portion 221 is provided on the side of the airbag 22 which is away from the resisting shell 211, and the airbag 22 can be inflated and deflated through the air receiving portion 221 to achieve expansion or contraction. The air receiving portion 221 passes through the supporting shell 212.

[0064] Specifically, when the airbag 22 is inflated, the airbag 22 expands toward the direction of the support shell 212 toward the resisting shell 211, thereby pushing the linkage assembly 25 to approach the resisting shell 211, and the linkage assembly 25 drives the first massage head 23 and the second massage head 24 to approach each other. When the airbag 22 is deflated, the airbag 22 shrinks toward the direction of the resisting shell 211 toward the support shell 212, and the first massage head 23 and the second massage head 24 automatically reset and move away from each other, thereby driving the linkage assembly 25 to follow the movement of the airbag 22 and approach the support shell 212, so that the first massage head 23 and the second massage head 24 complete a reciprocating motion process. Among them, the airbag 22 includes a capsule 222 and an air receiving portion 221. The capsule 222 is arranged between the linkage assembly 25 and the support shell 212. The air receiving portion 221 is connected to the capsule 222, so that the capsule 222 can be inflated and deflated through the air receiving portion 221. Furthermore, the air receiving portion 221 is connected to a side of the bladder body 222 close to the supporting shell 212 and passes through the supporting shell 212. Such a configuration can prevent the air receiving portion 221 from occupying the accommodating cavity X4, thereby preventing the air receiving portion 221 from interfering with the movement of the airbag 22.

[0065] Furthermore, the pinching mechanism 20 may also include a first elastic component 26 and a second elastic component 27. At least one first elastic component 26 elastically abuts between the first massage head 23 and the housing 21. When the airbag 22 expands to drive the first massage head 23 to gradually approach the second massage head 24, the elastic potential energy of the first elastic component 26 between the first massage head 23 and the housing 21 gradually increases, that is, the elastic abutment effect of the first elastic component 26 on the first massage head 23 and the housing 21 gradually increases. When the airbag 22 contracts, the first elastic component 26 releases the elastic potential energy, so that the first massage head 23 automatically resets, that is, the first elastic component 26 drives the first massage head 23 to gradually move away from the second massage head 24 through elastic action. Similarly, at least one second elastic component 27 elastically abuts between the second massage head 24 and the housing 21. When the airbag 22 expands to drive the second massage head 24 to gradually approach the second massage head 24, the elastic potential energy of the second elastic component 27 between the second massage head 24 and the housing 21 gradually increases, that is, the elastic contact effect of the second elastic component 27 on the second massage head 24 and the housing 21 gradually increases. When the airbag 22 contracts, the second elastic component 27 releases the elastic potential energy, so that the second massage head 24 automatically resets, that is, the second elastic component 27 drives the second massage head 24 to gradually move away from the second massage head 24 through elastic action.

[0066] Please refer to Figure 6 and Figure 7The clamping mechanism 20 also includes a linkage assembly 25, which includes a force plate 251 and a first transmission arm 252. The force plate 251 is connected to the airbag 22 and can move closer to or farther from the intermediate bracket 13 (or closer to or farther from the support shell 212) along the first direction Y3 during the expansion or contraction of the airbag 22. The first direction Y3 is the arrangement direction of the force plate 251 and the airbag 22. A first guide portion 2511 is provided at one end of the force plate 251. The first transmission arm 252 has a first end D1 and a second end D2. The first end D1 is slidably connected to the first guide portion 2511. The second end D2 is connected to the first massage head 23. When the force plate 251 moves along the first direction Y3, the first transmission arm 252 moves along the first direction Y3 under the restriction of the first guide portion 2511, and slides along the second direction Y4 relative to the first guide portion 2511. The first transmission arm 252 performs a combined rotational motion in the first direction Y3 and the second direction Y4 , thereby making the first massage head 23 approach to or move away from the second massage head 24 .

[0067] Specifically, the force-bearing plate 251 includes a plate body 2513 and a first guide portion 2511. The plate body 2513 is in the shape of a flat plate or a substantially flat plate, and its extension direction is the same as the extension direction of the housing 21. The plate body 2513 is connected to the side of the airbag 22 away from the support shell 212. When the airbag 22 expands, the airbag 22 drives the force-bearing plate 251 to move in the direction of the airbag 22 toward the force-bearing plate 251. When the airbag 22 contracts, the first elastic member and the second elastic member drive the force-bearing plate 251 to move in the direction of the force-bearing plate 251 toward the airbag 22. The orthographic projection of the plate body 2513 on the airbag 22 can all fall within the range of the airbag 22, so that the airbag 22 can ensure that the plate body 2513 is evenly applied with force, so that the plate body 2513 moves more smoothly without being skewed. The first guide portion 2511 is connected to one end of the plate body 2513 in the extension direction, and moves synchronously with the plate body 2513. The first guide portion 2511 and the plate body 2513 may be an integrated structure or a separate structure.

[0068] Furthermore, the first transmission arm 252 is a connecting rod, which is connected between the first guide portion 2511 and the first massage head 23, and the first transmission arm 252 is slidably connected to the first guide portion 2511, and the first transmission arm 252 is fixedly connected to the first massage head 23. Since the airbag 22 expands or contracts, the force-bearing plate 251 can move along the first direction Y3, so the first transmission arm 252 will also move in the first direction Y3 under the restriction of the first guide portion 2511. At the same time, since the first transmission arm 252 is slidably connected to the first guide portion 2511, the first transmission arm 252 will also slide relative to the first guide portion 2511, and the sliding direction is the second direction Y4, and the first direction Y3 and the second direction Y4 are inclined to each other. Since the first transmission arm 252 moves in both the first direction Y3 and the second direction Y4, it is compounded into a rotational motion, that is, the first transmission arm 252 rotates relative to the first guide portion 2511, so that the first massage head 23 can approach or move away from the second massage head 24. Furthermore, since the first transmission arm 252 can both slide and rotate relative to the first guide portion 2511, the first transmission arm 252 and the first guide portion 2511 can be matched in a shaft-slot manner. Figure 7 As shown, a slide groove is provided on the first guide portion 2511, and the slide groove extends along the second direction Y4, and a cylindrical matching shaft is provided on the first transmission arm 252, and the matching shaft is inserted into the slide groove. Of course, the setting positions of the slide groove and the matching shaft can also be interchanged, that is, the cylindrical matching shaft is provided on the first guide portion 2511, and the slide groove extending along the second direction Y4 is provided on the first transmission arm 252.

[0069] In this embodiment, when the airbag 22 drives the force plate 251 to move in the first direction Y3, the force plate 251 can not only drive the first transmission arm 252 to move in the first direction Y3, but also enable the first transmission arm 252 to be displaced in the second direction Y4, so that the first transmission arm 252 can achieve a combined rotational motion in the first direction Y3 and the second direction Y4. In this way, the first transmission arm 252 can rotate smoothly without getting stuck and can also have a large rotation range, which is beneficial to enhance the massage strength of the first massage head 23 and achieve a high-intensity massage.

[0070] Please refer to Figures 8 to 9Optionally, the linkage assembly 25 further includes a second transmission arm 253. The force plate 251 is connected to the airbag 22 and can move closer to or farther from the intermediate bracket 13 along the first direction Y3 during the expansion or contraction of the airbag 22. The end of the force plate 251 away from the first guide portion 2511 is provided with a second guide portion 2512. The second transmission arm 253 has a third end D3 and a fourth end D4. The third end D3 is slidably connected to the second guide portion 2512. The fourth end D4 is connected to the second massage head 24. When the force plate 251 moves along the first direction Y3, the second transmission arm 253 moves along the first direction Y3 under the restriction of the second guide portion 2512, and slides along the third direction Y5 relative to the second guide portion 2512. The second transmission arm 253 combines the first direction Y3 and the third direction Y5 into a rotational motion, thereby enabling the second massage head 24 to move closer to or farther from the first massage head 23. Among them, the first direction Y3, the second direction Y4, and the third direction Y5 are inclined to each other.

[0071] Please refer to Fig. 9 The two opposite ends of the first guide portion 2511 are defined as a first guide end portion 2511a and a second guide end portion 2511b, respectively. The first guide end portion 2511a is closer to the second transmission arm 253 than the second guide end portion 2511b, and the relative direction of the first guide end portion 2511a and the second guide end portion 2511b is the second direction Y4. The two opposite ends of the second guide portion 2512 are defined as a third guide end portion 2512a and a fourth guide end portion 2512b, respectively. The third guide end portion 2512a is closer to the first transmission arm 252 than the fourth guide end portion 2512b, and the relative direction of the third guide end portion 2512a and the fourth guide end portion 2512b is the third direction Y5. Furthermore, when the airbag 22 expands, the force plate 251 approaches the middle bracket 13, the first end D1 of the first transmission arm 252 moves along the first guide end 2511a toward the second guide end 2511b, and the first massage head 23 approaches the second massage head 24; the third end D3 of the second transmission arm 253 moves along the third guide end 2512a toward the fourth guide end 2512b, and the second massage head 24 approaches the first massage head 23. Conversely, when the airbag 22 contracts, the force plate 251 moves away from the middle bracket 13, the first end D1 of the first transmission arm 252 moves along the second guide end 2511b toward the first guide end 2511a, and the first massage head 23 moves away from the second massage head 24; the third end D3 of the second transmission arm 253 moves along the fourth guide end 2512b toward the third guide end 2512a, and the second massage head 24 moves away from the first massage head 23.

[0072] In this embodiment, the first transmission arm 252 and the second transmission arm 253, as well as the first guide portion 2511 and the second guide portion 2512 can be symmetrically arranged, so that the first massage head 23 and the second massage head 24 can have the same swing amplitude, thereby providing the same massage intensity. For the details of the second transmission arm 253, the second guide portion 2512, and the second massage head 24, please refer to the above description of the first transmission arm 252, the first guide portion 2511, and the first massage head 23, which will not be repeated here.

[0073] Please refer to Fig. 9 , the first transmission arm 252 has a first inclined surface 2521. The first inclined surface 2521 faces the connection between the first elastic arm 11 and the intermediate bracket 13. The first inclined surface 2521 is arranged to be inclined relative to the first direction Y3. It can be understood that since the first transmission arm 252 is rotatable, a certain range of rotation space is required. In this embodiment, the first inclined surface 2521 is arranged to be inclined relative to the first direction Y3, so as to provide a larger space for the rotation of the first transmission arm 252, avoid hitting the housing 21 during the rotation process, and enable the first massage head 23 to have a sufficient swing amplitude to provide a strong massage effect to the neck.

[0074] Optionally, the second transmission arm 253 has a second inclined surface 2531. The second inclined surface 2531 faces the connection between the second elastic arm 12 and the intermediate bracket 13. The second inclined surface 2531 is inclined relative to the second direction Y4. In this way, a larger space can be provided for the rotation of the second transmission arm 253, so that the second massage head 24 has a sufficient swing amplitude to provide a strong massage effect to the neck.

[0075] Please refer to Fig. 9 , the angle α1 formed by the first direction Y3 and the second direction Y4 satisfies: 0°<α1≤60°. Among them, α1 can be 0°, 15°, 20°, 21°, 26°, 30°, 35°, 39°, 40°, 45°, 50°, 53°, 56°, 60°, etc. In this way, the force-bearing plate 251 can apply a larger oblique force component to the first end D1 of the first transmission arm 252, so that the first end D1 moves in the second direction Y4, thereby easily driving the first transmission arm 252 to rotate, so that the first massage head 23 can output a larger massage force.

[0076] Please refer to Fig. 9Optionally, the angle α2 formed by the first direction Y3 and the third direction Y5 satisfies: 0°<α2≤60°. Among them, α1 can be 0°, 15°, 20°, 21°, 26°, 30°, 35°, 39°, 40°, 45°, 50°, 53°, 56°, 60°, etc. In this way, the force-bearing plate 251 can apply a larger oblique force component to the third end D3 of the second transmission arm 253 so that the third end D3 moves in the third direction Y5, thereby easily driving the second transmission arm 253 to rotate, so that the second massage head 24 can output a larger massage force.

[0077] Please refer to Figure 8 The shell 21 includes a support shell 212 and a resisting shell 211, and a force plate 251 is arranged between the support shell 212 and the resisting shell 211. The opposite sides of the airbag 22 are connected to the force plate 251 and the support shell 212 respectively. The maximum displacement of the force plate 251 in the first direction Y3 is less than the maximum telescopic height of the airbag 22 in the natural state, so that the airbag 22 can be pressed between the force plate 251 and the support shell 212 when the airbag 22 is kept in the inflated state. Among them, the maximum displacement of the force plate 251 in the first direction Y3 refers to the displacement required for the force plate 251 to move from the position closest to the support shell 212 to the position farthest from the support shell 212 along the first direction Y3. The maximum telescopic height of the airbag 22 in the natural state refers to the maximum expandable size of the airbag 22 in the first direction Y3 when it is not restricted by the outside world. Therefore, the airbag 22 located in the accommodating space cannot expand to the maximum telescopic height in the first direction Y3. It can be understood that when the airbag 22 located in the accommodating space has not reached the maximum telescopic height, the resisting shell 211 can resist the force plate 251, and the opposite sides of the airbag 22 can be tightly abutted against the force plate 251 and the supporting shell 212. At this time, the force plate 251 can maintain stability under the action of the airbag 22 and the resisting shell 211, so that the first massage head 23 and the second massage head 24 can always reach the minimum distance during multiple cycles of massage, thereby maintaining a stable massage force.

[0078] Please refer to Figure 8Optionally, the telescopic stroke of the airbag 22 in the first direction Y3 within a preset time is a. The movement stroke of the first massage head 23 driven by the airbag 22 in the massage direction Y6 within a preset time is b. That is to say, if the telescopic stroke of the airbag 22 in the first direction Y3 is a, the movement stroke of the first massage head 23 in the massage direction Y6 is b. The telescopic stroke a and the movement stroke b have the following relationship: 1 / 3≤a / b≤2 / 3, and the specific value of a / b can be but is not limited to 1 / 3, 0.4, 1 / 2, 0.6, 2 / 3, etc. Among them, the first direction Y3 is the relative direction of the intermediate bracket 13 and the clamping mechanism 20. The massage direction Y6 is the relative direction of the first elastic arm 11 and the second elastic arm 12, or the massage direction Y6 is the relative direction of the first massage head 23 and the second massage head 24. It is understandable that if the value of a / b is less than 1 / 3, it means that the value of b is relatively large, that is, the first massage head 23 can generate a large movement stroke in the massage direction Y6, which will cause the massage head strength of the first massage head 23 in the massage direction Y6 to be too large. If the value of a / b is greater than 2 / 3, it means that the value of b is relatively small, that is, the first massage head 23 can generate a small movement stroke in the massage direction Y6, which will cause the massage head strength of the first massage head 23 in the massage direction Y6 to be too small. The value of a / b is greater than 2 / 3, which also means that the value of a is relatively large, that is, the airbag 22 needs to generate a large telescopic stroke in the first direction Y3, which will cause the required accommodation space of the airbag 22 in the first direction Y3 to be too large, thereby causing the massage device 100 to be too large. In this embodiment, the value of a / b is limited to 1 / 3 to 2 / 3, so that the values ​​of a and b are appropriate, so that the airbag 22 can drive the first massage head 23 to produce a larger movement stroke within a smaller telescopic stroke range, thereby ensuring that the first massage head 23 can provide sufficient massage force without injuring the user, and also avoiding the massage device 100 from being too large.

[0079] Please refer to Figure 8Optionally, the telescopic stroke of the airbag 22 in the first direction Y3 within a preset time is a. The movement stroke of the second massage head 24 driven by the airbag 22 in the massage direction Y6 within a preset time is c. That is to say, if the telescopic stroke of the airbag 22 in the first direction Y3 is a, the movement stroke of the second massage head 24 in the massage direction Y6 is c. The telescopic stroke a and the movement stroke c have the following relationship: wherein 1 / 3≤a / c≤2 / 3. The specific value of a / c can be, but is not limited to, 1 / 3, 0.4, 1 / 2, 0.6, 2 / 3, etc. wherein the first direction Y3 is the relative direction between the intermediate bracket 13 and the clamping mechanism 20. The massage direction Y6 is the relative direction between the first elastic arm 11 and the second elastic arm 12, or the massage direction Y6 is the relative direction between the first massage head 23 and the second massage head 24. It is understandable that if the value of a / c is less than 1 / 3, it means that the value of c is relatively large, that is, the second massage head 24 can generate a large movement stroke in the massage direction Y6, which will cause the massage head strength of the second massage head 24 in the massage direction Y6 to be too large. If the value of a / c is greater than 2 / 3, it means that the value of c is relatively small, that is, the second massage head 24 can generate a small movement stroke in the massage direction Y6, which will cause the massage head strength of the second massage head 24 in the massage direction Y6 to be too small. The value of a / c is greater than 2 / 3, which also means that the value of a is relatively large, that is, the airbag 22 needs to generate a large telescopic stroke in the first direction Y3, which will cause the airbag 22 to require too much accommodation space in the first direction Y3, thereby causing the massage device 100 to be too large. In this embodiment, the value of a / c is limited to 1 / 3 to 2 / 3, so that the values ​​of a and c can be appropriate, so that the airbag 22 can drive the second massage head 24 to produce a larger movement stroke within a smaller telescopic stroke range, thereby ensuring that the second massage head 24 can provide sufficient massage force without injuring the user, and also avoiding the massage device 100 from being too large.

[0080] It should be noted that in the above embodiment, the telescopic stroke of the airbag 22 refers to the sum of the expansion stroke and the contraction stroke of the airbag 22 in the first direction Y3, that is, the telescopic stroke is the sum of the expansion size change (expansion amount) and the contraction size change (contraction amount) of the airbag 22 in the first direction Y3. For example, the expansion amount of the airbag 22 in the first direction Y3 is x, and the contraction amount is 0. Therefore, the telescopic stroke is a=x (that is, a=x+0). For another example, the expansion amount of the airbag 22 in the first direction Y3 is x, and the contraction amount is x. Therefore, the telescopic stroke is a=2*x (that is, a=x+x). Similarly, the moving stroke of the first massage head 23 refers to the sum of the moving stroke of the first massage head 23 in the first sub-direction and the moving stroke in the second sub-direction, that is, the sum of the movement amounts of the first massage head 23 in the first sub-direction and the second sub-direction, wherein the first sub-direction is the direction of the first massage head 23 toward the second massage head 24, and the second sub-direction is the opposite direction of the first sub-direction. For example, the moving stroke of the first massage head 23 in the first sub-direction is 0, and the moving stroke in the second sub-direction is y, therefore, the moving stroke b of the first massage head 23 is y (that is, b=0+y). For another example, the moving stroke of the first massage head 23 in the first sub-direction is y, and the moving stroke in the second sub-direction is y, therefore, the moving stroke b of the first massage head 23 is 2*y (that is, b=y+y). Similarly, the moving stroke of the second massage head 24 refers to the sum of the moving stroke of the second massage head 24 in the first sub-direction and the moving stroke in the second sub-direction, that is, the sum of the movement amounts of the second massage head 24 in the first sub-direction and the second sub-direction, wherein the first sub-direction is the direction of the first massage head 23 toward the second massage head 24, and the second sub-direction is the opposite direction of the first sub-direction. For example, the moving stroke of the second massage head 24 in the first sub-direction is 0, and the moving stroke in the second sub-direction is z. Therefore, the moving stroke c of the second massage head 24 is z (that is, c=0+z). For another example, the moving stroke of the second massage head 24 in the first sub-direction is z, and the moving stroke in the second sub-direction is z. Therefore, the moving stroke c of the second massage head 24 is 2*z (that is, c=z+z).

[0081] Please refer to Figure 8 , the maximum telescopic height h of the airbag 22 in the housing 21 satisfies: h≤13mm. The value of h can be, but is not limited to, 13mm, 12.5mm, 12mm, 11.6mm, 11.3mm, 10mm, etc. The maximum telescopic height refers to the maximum dimensional change of the airbag 22 in the first direction Y3. In this embodiment, the maximum telescopic height h of the airbag 22 is limited to less than or equal to 13mm, so that the first massage head 23 and the second massage head 24 can output sufficient massage force, and the telescopic height of the airbag 22 is not too high, thereby avoiding the massage device 100 from being too large.
