Description

Technical Field

[0001] This utility model relates to the field of massage technology, and in particular to a waist massage mechanism and massage belt. Background Technology

[0002] Prolonged exercise, standing, or desk work can cause fatigue in certain parts of the body, and in severe cases, injury. The lower back is one of the areas most prone to fatigue and injury. To alleviate lower back fatigue and injury, designers have created lower back massage devices that allow users to massage their lower back, thereby reducing lumbar muscle strain. The massage mechanism inside these devices is a key factor in improving the massage effect and comfort.

[0003] However, the massage mechanisms in related technologies usually lack elasticity or folding structures, and their contact with the human waist is a hard contact. They cannot adapt well to the curves of the human waist, resulting in a poor fit between the massage heads on the massage mechanism and the human waist, which in turn leads to poor massage effect and comfort.

[0014] As an optional implementation, in an embodiment of the first aspect of the present invention, the first baffle plate has an arc-shaped structure surrounding the worm gear.

[0015] As an optional implementation, in an embodiment of the first aspect of this utility model, both the first housing assembly and the second housing assembly include an inner housing, a middle housing, and an outer housing arranged along the thickness direction of the housing structure.

[0016] As an optional implementation, in an embodiment of the first aspect of the present invention, in the direction from the housing structure to the massage structure, the skin-proximal surface of the first shield is lower than the skin-proximal surface of the first housing assembly or the second housing assembly to form a first stepped structure.

[0020] Secondly, this utility model discloses a massage waist belt, which includes a waist belt body and a waist massage mechanism as described in the first aspect above.

[0021] As an optional implementation, in an embodiment of the second aspect of this utility model, the waist belt body includes a first belt body and a second belt body.

The first belt body and the second belt body are connected to bind the waist massage mechanism to the waist of the human body. When the massage waist belt is bound to the waist of the human body, the first housing assembly and the second housing assembly rotate under the drive of the first belt body and the second belt body to adapt to the shape of the human waist; or,

[0022] The waist belt body is connected to the distal surface of the first housing assembly and the second housing assembly respectively, and the two ends of the waist belt body are connected to bind the waist massage mechanism to the waist of the human body. When the massage waist belt is bound to the waist of the human body, the first housing assembly and the second housing assembly rotate under the drive of the waist belt body to adapt to the shape of the human waist.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] The waist massage mechanism and massage belt provided in this embodiment of the utility model are configured by setting a first transmission group inside the first housing assembly and a second transmission group inside the second housing assembly, and movably passing the worm gear of the motor through the first shaft connection of the first housing assembly and the second shaft connection of the second housing assembly. At the same time, a hollow part is provided in the first shaft connection to expose the spiral teeth of the worm gear, so that the two sides of the worm gear can be connected to the first transmission wheel group and the second transmission wheel group respectively. On the one hand, the same worm gear can drive the first and second transmission wheel sets to rotate, eliminating the need for multiple motors or worm gears at both ends of the same motor to drive the first and second transmission wheel sets. This reduces the number of components, lowers the weight of the waist massage mechanism, simplifies the motor structure, and reduces the space occupied by the motor within the housing structure. This allows for a lightweight and miniaturized design of the waist massage mechanism, reducing the burden on the user's waist and improving massage comfort. On the other hand, since the motor's worm gear rotatably passes through the first and second shaft connections, it can also serve as the pivot of the first and second housing components. This reuse of the worm gear as a pivot further reduces the number of components, thereby further reducing the weight and structural complexity of the waist massage mechanism.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first housing assembly may be referred to as a second housing assembly, and similarly, a second housing assembly may be referred to as a first housing assembly. Both the first housing assembly and the second housing assembly are housing assemblies, but they are not the same housing assembly.

[0046] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0047] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0048] It is well known that prolonged sitting can easily cause the lumbar muscles to be in a state of high tension for extended periods, damaging their health and leading to lumbar muscle strain. However, manual lumbar massage is not only time-consuming and laborious, making it difficult to maintain for long periods, but also results in poor massage effects due to limitations in technique and strength control. To meet market demand, electric massage belts for lumbar massage have emerged. These belts can be worn on the waist without being handheld, automatically massaging the lower back through massage heads to relieve fatigue and injury. The internal massage mechanism of the belt is the key factor in improving the massage effect and comfort.

[0049] However, in related technologies, in order to better support and fix the massage head, drive device and other structures, the shell structure of the waist massage mechanism is generally a rigid shell, and usually does not have an elastic or folding structure. As a result, the shell structure cannot adapt to the curve changes of the human waist, resulting in a poor fit between the massage head and the human waist. Consequently, the massage effect and comfort of the waist massage mechanism are also relatively poor.

[0050] While there are existing technologies that design the housing structure to include a first housing component and a second housing component that can rotate relative to each other, allowing the housing structure to adapt to the curves of the human waist, it usually requires separate drive devices inside the first and second housing components to drive the massage heads on the first and second housing components to perform massage movements. This increases the structural complexity of the waist massage mechanism, leading to increased costs and weight. It also increases the load on the waist massage mechanism when worn on the human waist, resulting in a poor massage experience for the user.

[0051] In view of this, the present application provides a waist massage mechanism that can adapt to the curve changes of the human waist to better fit the human waist and is lightweight, thereby reducing the burden on the human waist when the waist massage mechanism is worn, and improving massage comfort and massage effect.

[0052] Specifically, please refer to Figure 1The lumbar massage mechanism 10 provided in this embodiment includes a housing structure 11, a massage structure 12, and a motor 13. The housing structure 11 includes a first housing assembly 11a and a second housing assembly 11b. The massage structure 12 is movably disposed on the housing structure 11 and located on the skin-proximal side of the housing structure 11. Therefore, when the lumbar massage mechanism 10 is worn on the waist, the massage mechanism is not obstructed by the housing structure 11 and can contact the waist, thereby massaging the waist to relieve fatigue and injury. Furthermore, the massage structure 12 includes a first massage group 121 and a second massage group 122. The first massage group 121 is movably disposed on the first housing assembly 11a, and the second massage group 122 is movably disposed on the second housing assembly 11b.

[0053] Please see Figure 2 and Figure 3 In this application, the first housing assembly 11a is provided with a first shaft connection portion 111, and the second housing assembly 11b is provided with a second shaft connection portion 112. The second shaft connection portion 112 is rotatably connected to the first shaft connection portion 111, so that the first housing assembly 11a and the second housing assembly 11b can rotate relative to each other. That is, when the waist massage mechanism 10 is worn on the waist of the human body for massage, the first housing assembly 11a and the second housing assembly 11b can deflect and move closer to each other according to the waist curve of the user, adjusting the folding angle between the first housing assembly 11a and the second housing assembly 11b. The first housing assembly 11a is provided with a first transmission wheel set 14, and the second housing assembly 11b is provided with a second transmission wheel set 15. The first massage group 121 is connected to the first transmission wheel set 14 for mounting on the first housing assembly 11a, and the second massage group 122 is connected to the second transmission wheel set 15 for mounting on the second housing assembly 11b.

[0054] Please see Figure 3 and Figure 4In this application, the motor 13 is fixed to the housing structure 11, and the output shaft of the motor 13 is connected to a worm gear 131, which is rotatably inserted through the first shaft joint 111 and the second shaft joint 112. The first shaft connection 111 has a hollow portion 113 for receiving the helical teeth 132 of the worm gear 131, and the first shaft connection 111 also has a hollow portion 114 to expose the helical teeth 132 of the worm gear 131, so that the two sides of the worm gear 131 can be connected to the first transmission wheel set 14 and the second transmission wheel set 15 respectively. Thus, when the motor 13 drives the worm gear 131 to rotate, the worm gear 131 synchronously drives the first transmission wheel set 14 and the second transmission wheel set 15 to rotate. This allows the first massage group 121 to perform at least one of rotational motion, oscillating motion or linear motion under the rotation of the first transmission wheel set 14, and the second massage group 122 to perform at least one of rotational motion, oscillating motion or linear motion under the rotation of the second transmission wheel set 15, thereby achieving the effect of massaging the waist of the human body.

[0055] In the above design, on the one hand, the rotational motion of the first transmission wheel set 14 and the second transmission wheel set 15 can be driven by the same worm gear 131. This eliminates the need for multiple motors 13, and also eliminates the need for worm gears 131 at both ends of the same motor 13 to drive the first transmission wheel set 14 and the second transmission wheel set 15 through different worm gears 131. This reduces the number of components used, lowers the weight of the waist massage mechanism 10, simplifies the structure of the motor 13, and reduces the space occupied by the motor 13 within the housing structure 11, thus enabling the waist massager to function properly. The lightweight and miniaturized design of the core 10 helps to reduce the burden on the waist when the waist massage core 10 is worn, thus improving the massage comfort of the waist massage core 10. On the other hand, since the worm gear 131 of the motor 13 is rotatably passed through the first shaft joint 111 and the second shaft joint 112, the worm gear 131 can be used as the pivot of the first housing assembly 11a and the second housing assembly 11b. This allows the worm gear 131 to be reused as a pivot, further reducing the number of parts used, thereby further reducing the weight and structural complexity of the waist massage core 10.

[0056] In addition, the first shaft connection 111 of the first housing assembly 11a and the second shaft connection 112 of the second housing assembly 11b are rotatably connected by a worm gear 131, so that the first massage group 121 on the first housing assembly 11a and the second massage group 122 on the second housing assembly 11b can deflect and move closer to each other. Thus, during massage, the folding angle of the waist massage mechanism 10 can be automatically adjusted according to the user's waist curve. That is, the first housing assembly 11a and the second housing assembly 11b can be adaptively rotated and adjusted according to the shape or position of the human waist, so that the first massage group 121 on the first housing assembly 11a and the second massage group 122 on the second housing assembly 11b can fit the human waist better, thereby improving the fit and adaptability of the waist massage mechanism 10 to the human waist and enhancing the massage experience of the waist massage mechanism 10.

[0057] However, in the above design, the applicant discovered through research that although the hollowed-out portion 114 allows the spiral teeth 132 of the worm gear 131 to be exposed on the first shaft connection portion 111 so that the two sides of the worm gear 131 can be connected to the first transmission wheel set 14 and the second transmission wheel set 15 respectively, foreign objects can also enter the worm gear 131 through the hollowed-out portion 114, and even the user's clothes can be caught in the worm gear 131 through the hollowed-out portion 114, which will affect the rotation of the worm gear 131, and in turn affect the movement of the first massage group 121 and the second massage group 122, thus affecting the massage effect of the first massage group 121 and the second massage group 122.

[0058] In this regard, such as Figure 4 , Figure 5 and Figure 6 As shown, in this application, a first shielding plate 115 is provided on the skin-proximal side of one of the first housing assembly 11a and the second housing assembly 11b, and the other of the first housing assembly 11a and the second housing assembly 11b is provided with a first clearance space 116 to avoid the first shielding plate 115. The first shielding plate 115 can rotate and be embedded in the first clearance space 116 with the first housing assembly 11a or the second housing assembly 11b. That is, when the first shielding plate 115 is provided on the skin-proximal side of the first housing assembly 11a, the second housing assembly 11b is provided with a first clearance space 116 to avoid the first shielding plate 115, and the first shielding plate 115 can rotate and be embedded in the first clearance space 116 with the first housing assembly 11a; and when the first shielding plate 115 is provided on the skin-proximal side of the second housing assembly 11b, the first housing assembly 11a is provided with a first clearance space 116 to avoid the first shielding plate 115, and the first shielding plate 115 can rotate and be embedded in the first clearance space 116 with the second housing assembly 11b. Furthermore, when the angle between the first housing assembly 11a and the second housing assembly 11b is at its maximum, the first shielding plate 115 completely blocks the helical teeth 132 on the side of the housing structure 11 near the skin surface.

[0059] This application provides a first baffle 115 in one of the first housing assembly 11a and the second housing assembly 11b, and a first clearance space 116 in the other. This allows the first baffle 115 to rotate with the first housing assembly 11a or the second housing assembly 11b and be embedded in the first clearance space 116, so as not to affect the rotation of the first housing assembly 11a and the second housing assembly 11b. At the same time, the first baffle 115 can also block the helical teeth 132 of the worm gear 131 to prevent foreign objects from entering the worm gear 131 and causing the worm gear 131 to not rotate properly. This ensures that the worm gear 131 can smoothly drive the massage structure 12 to move, thereby ensuring the massage effect of the massage structure 12.

[0060] The maximum angle between the first housing assembly 11a and the second housing assembly 11b can be understood as follows: when the first housing assembly 11a cannot approach the distal skin side of the second housing assembly 11b, and the second housing assembly 11b cannot approach the distal skin side of the first housing assembly 11a, the angle between the first housing assembly 11a and the second housing assembly 11b is usually the angle between the first housing assembly 11a and the second housing assembly 11b when the first housing assembly 11a and the second housing assembly 11b are flat, for example, about 180°.

[0061] As one example, such as Figure 3 and Figure 4 As shown, the first shaft connection 111 includes a first sub-shaft connection 111a and a second sub-shaft connection 111b. The first sub-shaft connection 111a and the second sub-shaft connection 111b are respectively located on both sides of the hollow portion 114 in the axial direction of the worm 131. The second shaft connection 112 is located between the first sub-shaft connection 111a and the second sub-shaft connection 111b. One end of the worm 131 is rotatably inserted into the first sub-shaft connection 111a, and the other end of the worm 131 is rotatably inserted into the second sub-shaft connection 111b.

[0062] The applicant discovered through research that if only one end of the worm gear 131 is rotatably connected to the first shaft connection 111, the other end of the worm gear 131 is essentially suspended in the air. This would result in insufficient structural stability of the worm gear 131, affecting the movement stability of the first massage group 121 and the second massage group 122. Furthermore, the force is concentrated at one end of the worm gear 131, which could easily affect its service life. Therefore, this application addresses this issue by placing the hollow portion 114 at the middle position of the first shaft connection 111 along the axial direction of the worm gear 131, so that the two ends of the first shaft connection 111 along the axial direction of the worm gear 131 are respectively... The formation of a first sub-shaft connector 111a and a second sub-shaft connector 111b allows both ends of the worm gear 131 to be rotatably connected to a sub-shaft connector. This enables the first sub-shaft connector 111a and the second sub-shaft connector 111b to constrain and support both ends of the worm gear 131, respectively. Meanwhile, compared to the second shaft connector 112 being located on the side of the first sub-shaft connector 111a away from the second sub-shaft connector 111b, the second shaft connector 112 being located between the first sub-shaft connector 111a and the second sub-shaft connector 111b allows for a more compact structure of the waist massage mechanism 10, achieving a miniaturized design.

[0063] As one example, such as Figure 3 and Figure 4 As shown, the first shaft connection 111 further includes a third sub-shaft connection 111c disposed between the first sub-shaft connection 111a and the second sub-shaft connection 111b, wherein the hollow portion 113 is divided into a first sub-hollow portion 113a and a second sub-hollow portion 113b by the third sub-shaft connection 111c, and the second shaft connection 112 is located in the second sub-hollow portion 113b. The worm gear 131 includes a worm main shaft 131a and a rotating connecting shaft 131b. A helical tooth 132 is formed on the worm main shaft 131a. The worm main shaft 131a is located in the first sub-hollow portion 113a. One end of the worm main shaft 131a is rotatably inserted through the first sub-shaft joint 111a, and the other end of the worm main shaft 131a is rotatably inserted through the third sub-shaft joint 111c. The rotating connecting shaft 131b is rotatably inserted through the second shaft joint 112. One end of the rotating connecting shaft 131b is connected to the other end of the worm main shaft 131a, and the other end of the rotating connecting shaft 131b is rotatably inserted through the third sub-shaft joint 111c.

[0064] Compared to using a single, longer worm gear 131, the worm gear 131 uses a split worm gear main shaft 131a and a rotating connecting shaft 131b. The lengths of both the worm gear main shaft 131a and the rotating connecting shaft 131b are relatively short, shorter than those of a single, longer worm gear 131. This makes them easier to manufacture and reduces the manufacturing difficulty, thereby reducing the difficulty in obtaining the components of the waist massage mechanism 10 and lowering the manufacturing cost of the waist massage mechanism 10.

[0065] In this application, one end of the worm gear spindle 131a is connected to the output shaft of the motor 13, so that the worm gear spindle 131a can rotate relative to the first sub-shaft joint 111a and the third sub-shaft joint 111c under the drive of the output shaft of the motor 13, and the active connecting shaft will rotate relative to the second shaft joint 112 and the second sub-shaft joint 111b as the worm gear spindle 131a rotates.

[0066] An exemplary combination Figures 7 to 9 As shown, the worm gear main shaft 131a can extend from the third sub-shaft connection 111c and pass through the second shaft connection 112. In this case, the rotating connecting shaft 131b can pass through the worm gear main shaft 131a, so as to indirectly pass through the second shaft connection 112 through the worm gear main shaft 131a. Alternatively, the rotating connecting shaft 131b can extend from the second shaft connection 112 and pass through the third sub-shaft connection 111c. In this case, the worm gear main shaft 131a can pass through the rotating connecting shaft 131b, so as to indirectly pass through the third sub-shaft connection 111c through the rotating connecting shaft 131b. Using these two methods increases the contact area between the worm gear main shaft 131a and the rotating connecting shaft 131b, thereby improving the connection stability between them.

[0067] Understandably, in other embodiments, the worm gear spindle 131a may be connected in contact with the axial end face of the rotating connecting shaft 131b to achieve the connection between the two.

[0068] As one example, such as Figure 3 and Figure 4 As shown, the first baffle plate 115 can extend to the location of the rotating connecting shaft 131b to block the rotating connecting shaft 131b. Since the gap between the first housing assembly 11a and the second housing assembly 11b is needed as the rotation space for the rotating connecting shaft 131b to rotate, extending the first baffle plate 115 to the location of the rotating connecting shaft 131b to block the rotating connecting shaft 131b can block the gap between the first housing assembly 11a and the second housing assembly 11b at the location of the rotating connecting shaft 131b, thereby better blocking debris to prevent debris from entering the worm gear 131 and affecting the rotation of the worm gear 131. This ensures that the worm gear 131 can drive the first massage group 121 and the second massage group 122 to move more smoothly, further ensuring the massage effect of the first massage group 121 and the second massage group 122.

[0069] As one example, such as Figure 5 and Figure 6As shown, the first baffle plate 115 can be an arc-shaped structure surrounding the worm gear 131. Since the worm gear 131 is cylindrical, setting the first baffle plate 115 to an arc-shaped structure surrounding the worm gear 131 can better shield the worm gear 131. When the first baffle plate 115 rotates with the first housing assembly 11a or the second housing assembly 11b, it can always wrap around the outside of the worm gear 131, thereby achieving a better shielding effect and better preventing foreign objects from entering the worm gear 131 and affecting its rotation. This ensures that the worm gear 131 can more smoothly drive the first massage group 121 and the second massage group 122 to move, further ensuring the massage effect of the first massage group 121 and the second massage group 122.

[0070] As one example, such as Figure 5 and Figure 6 As shown, both the first housing assembly 11a and the second housing assembly 11b include an inner housing 11a1, a middle housing 11a2, and an outer housing 11a3 arranged along the thickness direction of the housing structure 11. The middle housing 11a2 is connected between the inner housing 11a1 and the outer housing 11a3. The massage structure 12 is located on the skin-proximal side of the inner housing 11a1. The first baffle 115 is disposed on one of the inner housings 11a1 and between the other inner housing 11a1 and the middle housing 11a2. A first clearance space 116 is formed, that is, when the first baffle 115 is disposed on the inner shell 11a1 of the first shell assembly 11a, a first clearance space 116 is formed between the inner shell 11a1 and the intermediate shell 11a2 of the second shell assembly 11b; and when the first baffle 115 is disposed on the inner shell 11a1 of the second shell assembly 11b, a first clearance space 116 is formed between the inner shell 11a1 and the intermediate shell 11a2 of the first shell assembly 11a. The first shaft connection portion 111 and the second shaft connection portion 112 are respectively disposed on the two intermediate shells 11a2. The first transmission wheel set 14 is disposed in the space formed between the intermediate shell 11a2 and the outer shell 11a3 in the first shell assembly 11a, and the second transmission wheel set 15 is disposed in the space formed between the intermediate shell 11a2 and the outer shell 11a3 in the second shell assembly 11b.

[0071] This application designs the first housing assembly 11a and the second housing assembly 11b as a stacked three-layer housing structure 11, which ensures the structural strength of the first housing assembly 11a and the second housing assembly 11b. This ensures that the first housing assembly 11a and the second housing assembly 11b have sufficient strength to set and install the transmission wheel set (i.e., the first transmission wheel set 14 and the second transmission wheel set 15), the motor 13, and the massage structure 12, etc. In addition, this application also sets the first baffle plate 115 on the inner housing 11a1, so that the first baffle plate 115 can be as close as possible to the skin side of the first housing assembly 11a or the second housing assembly 11b. Compared with the first baffle plate 115 being set on the middle housing 11a2 or the outer housing 11a3, the first baffle plate 115 being set on the inner housing 11a1 can also cover the gap at the connection between the inner housing 11a1 and the middle housing 11a2. This can maximize the prevention of foreign objects from entering the gap between the first housing assembly 11a or the second housing assembly 11b, thereby preventing them from affecting the rotation of the worm gear 131.

[0072] As one example, such as Figure 7 As shown, in the direction from the housing structure 11 to the massage structure 12, the skin-proximal surface of the first baffle 115 is lower than the skin-proximal surface of the first housing assembly 11a or the second housing assembly 11b to form a first stepped structure 1151. This first stepped structure 1151 is used to abut against the first housing assembly 11a or the second housing assembly 11b. That is, when the skin-proximal surface of the first baffle 115 is lower than the skin-proximal surface of the first housing assembly 11a to form the first stepped structure 1151, the first stepped structure 1151 is used to contact the second housing assembly 11b, for example, the inner shell of the second housing assembly 11b. The body 11a1 abuts against the side of the first housing assembly 11a to limit the rotational travel of the first housing assembly 11a and the skin-proximal sides of the second housing assembly 11b when they approach each other; and when the skin-proximal surface of the first baffle 115 is lower than the skin-proximal surface of the second housing assembly 11b to form a first stepped structure 1151, the first stepped structure 1151 is used to abut against the side of the first housing assembly 11a, for example, the inner housing 11a1 of the first housing assembly 11a, to limit the rotational travel of the first housing assembly 11a and the skin-proximal sides of the second housing assembly 11b when they approach each other.

[0073] Therefore, when the first housing assembly 11a and the second housing assembly 11b rotate relative to each other and their skin-like sides approach each other, that is, when the first housing assembly 11a and the second housing assembly 11b are closed, a blocking structure can be formed at the first stepped structure 1151 to block the first housing assembly 11a or the second housing assembly 11b, so that the first housing assembly 11a and the second housing assembly 11b cannot continue to rotate relative to each other, thus limiting the folding range of the first housing assembly 11a and the second housing assembly 11b.

[0074] As one example, such as Figure 5 and Figure 6 As shown, a second shielding plate 117 is provided on the distal skin side of one of the first housing assembly 11a and the second housing assembly 11b, and the other of the first housing assembly 11a and the second housing assembly 11b is provided with a second clearance space 118 to avoid the second shielding plate 117. The second shielding plate 117 can rotate and be embedded in the second clearance space 118 with the first housing assembly 11a or the second housing assembly 11b. That is, when the second shielding plate 117 is provided on the distal skin side of the first housing assembly 11a, the second housing assembly 11b is provided with a second clearance space 118 to avoid the second shielding plate 117, and the second shielding plate 117 can rotate and be embedded in the second clearance space 118 with the first housing assembly 11a; and when the second shielding plate 117 is provided on the distal skin side of the second housing assembly 11b, the first housing assembly 11a is provided with a second clearance space 118 to avoid the second shielding plate 117, and the second shielding plate 117 can rotate and be embedded in the second clearance space 118 with the second housing assembly 11b. Furthermore, when the angle between the first housing assembly 11a and the second housing assembly 11b is at its minimum, the second shielding plate 117 completely blocks the helical teeth 132 on the side where the far surface of the housing structure 11 is located.

[0075] In this way, when the first and second housing assemblies are folded together, especially when they are fully folded, i.e., when the first housing assembly 11a cannot approach the skin-distal side of the second housing assembly 11b and the second housing assembly 11b cannot approach the skin-distal side of the first housing assembly 11a, the second baffle 117 can completely block the worm gear 131 to prevent debris from entering the worm gear 131, thereby avoiding any impact on the rotation of the worm gear 131. This ensures that the worm gear 131 can smoothly drive the first massage group 121 and the second massage group 122 to move, thereby ensuring the massage effect of the first massage group 121 and the second massage group 122.

[0076] The minimum angle between the first housing assembly 11a and the second housing assembly 11b can be understood as the angle between the first housing assembly 11a and the second housing assembly 11b when the first housing assembly 11a cannot approach the skin-proximal side of the second housing assembly 11b, and the second housing assembly 11b cannot approach the skin-proximal side of the first housing assembly 11a.

[0077] As one embodiment, the second baffle 117 can be an arc-shaped structure surrounding the worm gear 131. Since the worm gear 131 is cylindrical, setting the second baffle 117 to an arc-shaped structure surrounding the worm gear 131 can better shield the worm gear 131. When the second baffle 117 rotates with the first housing assembly 11a or the second housing assembly 11b, it can always wrap around the outside of the worm gear 131, thereby achieving a better shielding effect and better preventing debris from entering the worm gear 131 and affecting its rotation. This ensures that the worm gear 131 can more smoothly drive the first massage group 121 and the second massage group 122 to move, further ensuring the massage effect of the first massage group 121 and the second massage group 122.

[0078] For example, when both the first housing assembly 11a and the second housing assembly 11b include an inner housing 11a1, a middle housing 11a2, and an outer housing 11a3 arranged along the thickness direction of the housing structure 11, the second baffle 117 is disposed on one of the inner housings 11a1, and a second clearance space 118 is formed between the other inner housing 11a1 and the middle housing 11a2. That is, when the second baffle 117 is disposed on the inner housing 11a1 of the first housing assembly 11a, a second clearance space 118 is formed between the inner housing 11a1 and the middle housing 11a2 of the second housing assembly 11b; and when the second baffle 117 is disposed on the inner housing 11a1 of the second housing assembly 11b, a second clearance space 118 is formed between the inner housing 11a1 and the middle housing 11a2 of the second housing assembly 11b.

[0079] As one example, such as Figure 10 and Figure 11As shown, in the direction from the massage structure 12 to the housing structure 11, the distal surface of the second baffle 117 is lower than the distal surface of the first housing assembly 11a or the second housing assembly 11b to form a second stepped structure 1171. This second stepped structure 1171 is used to abut against the first housing assembly 11a or the second housing assembly 11b. That is, when the proximal surface of the second baffle 117 is lower than the distal surface of the first housing assembly 11a to form the second stepped structure 1171, the second stepped structure 1171 is used to abut against the second housing assembly 11b, for example, the side of the outer housing 11a3 of the second housing assembly 11b near the first housing assembly 11a, to limit the contact between the first housing assembly 11a and the second housing assembly 11b. The rotational travel of the near-skin surfaces of 1b when they move away from each other is also limited to the rotational travel of the far-skin surfaces of the first housing assembly 11a and the second housing assembly 11b when they move closer to each other. When the far-skin surface of the second baffle 117 is lower than the far-skin surface of the second housing assembly 11b to form a second stepped structure 1171, the second stepped structure 1171 is used to abut against the side of the first housing assembly 11a, for example, the outer shell side housing 11a3 of the first housing assembly 11a, near the side of the first housing assembly 11a, to limit the rotational travel of the near-skin surfaces of the first housing assembly 11a and the second housing assembly 11b when they move away from each other, that is, to limit the rotational travel of the far-skin surfaces of the first housing assembly 11a and the second housing assembly 11b when they move closer to each other.

[0080] Therefore, when the first housing assembly 11a and the second housing assembly 11b rotate relative to each other and their distal sides approach each other, that is, when the first housing assembly 11a and the second housing assembly 11b open, a blocking structure can be formed at the second stepped structure to block the first housing assembly 11a or the second housing assembly 11b and limit the opening range of the first housing assembly 11a and the second housing assembly 11b. This ensures that the first housing assembly 11a and the second housing assembly 11b are maintained at the maximum angle between them. For example, it can ensure that the first housing assembly 11a and the second housing assembly 11b are maintained in a state where they are flattened relative to each other.

[0081] Please see Figure 12 and Figure 13 This application also discloses a massage waist belt 100, which includes a waist belt body 20 and a waist massage mechanism 10 as described in any of the foregoing embodiments. The waist massage mechanism 10 is connected to the waist belt body 20, specifically by a housing structure 11 connected to the waist belt body 20, so that the waist belt body 20 can be used to wear the waist massage mechanism 10 on the waist of the human body, freeing the hands during massage and improving the convenience and comfort of using the massage waist belt 100.

[0082] As one embodiment, the waist belt body 20 includes a first belt body 21 and a second belt body 22. The waist belt body 20 is composed of at least a first belt body 21 and a second belt body 22, which are separately set. The first belt body 21 is connected to the end of the first housing assembly 11a away from the second housing assembly 11b, and the second belt body 22 is connected to the end of the second housing assembly 11b away from the first housing assembly 11a. The first belt body 21 and the second belt body 22 are connected to bind the waist massage core 10 to the waist of the human body. When the massage waist belt 100 is bound to the waist of the human body, the first housing assembly 11a and the second housing assembly 11b rotate under the drive of the first belt body 21 and the second belt body 22 to adapt to the shape of the human waist. Therefore, when the first belt body 21 and the second belt body 22 are attached to the waist of the human body, the first shell assembly 11a and the second shell assembly 11b can rotate around the waist under the drive of the first belt body 21 and the second belt body 22 to adapt to the shape of the waist, so as to better fit the curve of the human waist and better fit the human waist. This makes the massage belt 100 have the characteristics of high massage comfort and good massage effect, thereby enhancing the massage experience of the massage belt 100.

[0083] In another embodiment, the waist belt body 20 is an integral structure. The waist belt body 20 is connected to the distal surfaces of the first housing assembly 11a and the second housing assembly 11b, respectively, and both ends of the waist belt body 20 are connected to secure the waist massage mechanism 10 to the human waist. When the massage waist belt 100 is secured to the human waist, the first housing assembly 11a and the second housing assembly 11b rotate under the action of the waist belt body 20 to adapt to the shape of the human waist. Thus, when the waist belt body 20 is fixedly connected to the distal surfaces of the first housing assembly 11a and the second housing assembly 11b, under the action of the waist belt body 20, the first housing assembly 11a and the second housing assembly 11b can be better pushed to rotate to a suitable angle to better adapt to the shape of the human waist, thereby better conforming to the curve of the human waist and providing a better fit. This results in the massage waist belt 100 having high massage comfort and good massage effect, thus enhancing the massage experience.
