Description

Technical Field

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

[0002] Prolonged sitting can cause the lumbar muscles to be in a state of high tension for a long time, which can damage the health of the lumbar muscles and lead to lumbar muscle strain. Massage belts can massage the lumbar region and have a soothing effect, which is why they are popular.

[0003] Massage belts in related technologies typically include a belt body and a massage head. The massage head is fixed to the belt body and worn on the waist. However, the massage head cannot automatically adapt and deform to the contours of the waist, resulting in poor fit between the massage head and the waist, thus leading to poor massage effect and comfort. Summary of the Invention

[0004] This invention discloses a massage mechanism and a massage waist belt. The massage mechanism can improve the fit between the massage head and the skin of the waist, and has the advantages of good fit and good massage effect, thereby improving the comfort of the massage waist belt.

[0005] To achieve the above objectives, in a first aspect, the present invention discloses a massage mechanism, the massage mechanism comprising:

[0006] chassis;

[0007] A power mechanism, which is mounted on the housing; and

[0008] A massage component is connected to the power mechanism and located on the skin-proximal side of the housing. The massage component includes multiple massage heads arranged along the length of the housing. Under the driving action of the power mechanism, two adjacent massage heads move closer or further apart along the length of the housing. Each massage head extends along the width of the housing and includes multiple main body parts and at least one elastic connecting part arranged along the width of the housing. Any two adjacent main body parts are connected by an elastic connecting part. The elastic deformation capacity of the elastic connecting part is greater than that of the main body parts, so that the main body parts can float when subjected to force to press against the massage area.

[0009] As an optional implementation, in an embodiment of the first aspect of the present invention, each of the massage heads includes three main body portions and two elastic connecting portions. The three main body portions include a first main body portion and a second main body portion and a third main body portion symmetrically arranged about the first main body portion.

[0013] As an optional implementation, in an embodiment of the first aspect of the present invention, a groove is provided on the outer peripheral surface of the main body, and the edge of the flexible sleeve is bent toward the main body to form a snap-fit ​​portion, the snap-fit ​​portion being interference-fitted into the groove to restrict the flexible sleeve from detaching from the main body.

[0014] As an optional implementation, in an embodiment of the first aspect of the present invention, at least two adjacent massage heads are designated as a first sub-massage head and a second sub-massage head. The sides of the first and second sub-massage heads that are close to each other are each configured as a first side, and the sides of the first and second sub-massage heads that are far from each other are each configured as a second side. In the width direction of the housing, the width of the first side of the first sub-massage head is smaller than the width of the second side of the first sub-massage head, and the width of the first side of the second sub-massage head is smaller than the width of the second side of the second sub-massage head.

[0015] As an optional implementation, in an embodiment of the first aspect of the present invention, the plurality of massage heads are divided into two massage groups, which are respectively located on two opposite sides of the power mechanism along the length of the housing. The number of massage heads in each massage group is even, and two massage heads in each massage group form a pair of massage heads. The two massage heads in the pair of massage heads move closer to or further away from each other along the length of the housing under the driving action of the power mechanism.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The massage mechanism and massage belt provided in this invention have the following advantages: the massage head includes multiple main bodies arranged along the width of the massage belt and at least one elastic connecting part. Any two adjacent main bodies are connected by an elastic connecting part, so that the main bodies can float when subjected to force. Therefore, when the massage mechanism is worn on the waist, the main body can float with the adjacent main body as a fulcrum when subjected to the force of the waist, and bend towards the skin side of the housing. This allows the massage head to better fit the waist shape and better conform to the curve of the waist, resulting in a better massage effect and improved user massage comfort.

[0035] 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.

[0037] It is understood that the terms "first," "second," etc., used in this application may be used herein 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 body portion may be referred to as a second body portion, and similarly, a second body portion may be referred to as a first body portion. Both the first body portion and the second body portion are body portions, but they are not the same body portion.

[0038] 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.

[0039] 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 terms such as “comprising / including” or “having” 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. Furthermore, the term “and / or” as used in this specification is merely a description of the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. That is, the term “and / or” as used in this specification includes any and all combinations of the related listed items.

[0040] It is well known that prolonged sitting can 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 eliminate the need for manual massage; instead, they are fixed to the lumbar region and automatically massage the lower back, providing a soothing effect and reducing the occurrence of lumbar muscle strain.

[0041] In related technologies, massage belts mainly consist of a belt body and a massage head. The massage head is fixed to the belt body and worn on the waist. However, the massage head provided in related technologies cannot automatically adapt and deform to the contour of the waist, resulting in poor fit between the massage head and the waist, thus leading to poor massage effect and comfort.

[0042] In view of this, the present application provides a massage mechanism that, when applied to a massage waist belt and worn on the waist, allows the massage head to adapt to the shape of the waist and fit better against the waist, improving the fit between the massage head and the skin of the waist. This provides advantages such as good fit and good massage effect, thereby improving the comfort of the massage waist belt.

[0043] The technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0044] Please see Figure 1 , Figure 1 This is a structural schematic diagram from one side view of one implementation of the massage waist belt in this application. An embodiment of this application provides a massage waist belt 100, which includes a massage mechanism 10 and a waist belt body 20. The massage mechanism 10 is connected to the waist belt body 20 so that the waist belt body 20 can be used to wear the massage mechanism 10 on the waist of a person. This allows the massage mechanism 10 to be worn on the waist of a person through the waist belt body 20, thereby freeing the hands when the massage mechanism 10 massages the waist, improving the convenience and comfort of using the massage waist belt 100.

[0045] The massage belt 100 has a first direction f1, a second direction f2, and a third direction f3. When the massage belt 100 is in a flattened state, for example... Figure 1In the illustrated state, the first direction f1, the second direction f2, and the third direction f3 of the massage belt 100 are perpendicular to each other. When the massage belt 100 is worn on the waist, the first direction f1 of the massage belt 100 extends around the waist, the second direction f2 of the massage belt 100 extends along the direction of the spine, and the third direction f3 of the massage belt 100 is configured to point from the massage belt 100 towards the waist.

[0046] An example, such as Figure 1 As shown, the main body 20 of the waist belt can be an integral strip-shaped component, and the main body 20 of the waist belt extends along the first direction f1 of the massage waist belt 100. The massage mechanism 10 is approximately located at the middle position of the main body 20 of the waist belt in the first direction f1 of the massage waist belt 100. The massage mechanism 10 can be located inside the main body 20 of the waist belt or outside the main body 20 of the waist belt. The two ends of the main body 20 of the waist belt in the first direction f1 of the massage waist belt 100 can be connected by Velcro, D-ring buckle, etc., to fix it to the waist of the human body.

[0047] Another example, such as Figure 2 As shown, the main body 20 of the waist belt may include a first waist belt 21 and a second waist belt 22 that are separately arranged. The massage mechanism 10 is connected between the first waist belt 21 and the second waist belt 22. The first waist belt 21, the massage mechanism 10 and the second waist belt 22 are arranged sequentially along the first direction f1 of the massage waist belt 100. The first waist belt 21 and the second waist belt 22 are both strip-shaped structures extending along the first direction of the massage waist belt 100. The end of the first waist belt 21 away from the massage mechanism 10 and the end of the second waist belt 22 away from the massage mechanism 10 can be connected by Velcro, D-ring buckle or the like to fix it to the waist of the human body.

[0048] Please see Figure 2 and Figure 3 , Figure 3 This is a structural schematic diagram from one side view of one implementation of the massage mechanism in this application. The massage mechanism 10 provided in the embodiment of this application includes a housing 11, a power mechanism 12, and a massage element 13.

[0049] In this application, the housing 11 is connected to the waist belt body 20, and the housing 11 has a length direction f4, a width direction f5 and a thickness direction f6. The length direction f4 of the housing 11 extends along the first direction f1 of the massage waist belt 100, the width direction f5 of the housing 11 extends along the second direction f2 of the massage waist belt 100, and the thickness direction f6 of the housing 11 extends along the third direction f3 of the massage waist belt 100.

[0050] In this application, the power mechanism 12 is mounted on the housing 11. The power mechanism 12 can be located either outside or inside the housing 11. When the power mechanism 12 is located inside the housing 11, a portion of the power mechanism 12 is exposed outside the housing 11 to facilitate connection between the power mechanism 12 and the massage element 13.

[0051] In this application, as Figure 3 and Figure 4 As shown, the massage element 13 is connected to the power mechanism 12 and located on the skin-proximal side of the housing 11. The massage element 13 includes a plurality of massage heads 13a arranged along the length direction f4 of the housing 11. Under the driving action of the power mechanism 12, two adjacent massage heads 13a move closer or further apart along the length direction f4 of the housing 11 to achieve a massage effect on the massage area. Each massage head 13a extends along the width direction f5 of the housing 11, and each massage head 13a includes a plurality of main body parts 131 arranged along the width direction f5 of the housing 11 and at least one elastic connecting part 132. Any two adjacent main body parts 131 are connected by an elastic connecting part 132. The elastic deformation capacity of the elastic connecting part 132 is greater than that of the main body parts 131, so that the main body parts 131 can float when subjected to force to press against the massage area.

[0052] In the above design, when the massage mechanism 10 of this application is worn and fixed on the waist of the human body through the waist belt body, since the two adjacent main body parts 131 are connected by the elastic connecting part 132, and the elastic deformation capacity of the elastic connecting part 132 is greater than the elastic deformation capacity of the main body part 131, the main body part 131 can float with the other adjacent main body part 131 as the fulcrum when subjected to the force of the human waist, so as to bend towards the skin side of the housing 11. This allows the massage head 13a to better adapt to the shape of the waist and better fit the curve of the human waist. That is, it can improve the floating and skin-fitting ability of the massage head 13a, have better conformal deformation ability, and make the massage head 13a fit the waist of the human body better, so as to achieve a better massage effect and improve the user's massage comfort.

[0053] In this application, in order for the power mechanism 12 to drive the massage head 13a to move linearly along the length direction f4 of the housing 11, so that two adjacent massage heads 13a can move closer or further apart along the length direction f4 of the housing 11, the power mechanism 12 may include a mechanism that outputs linear motion, such as a hydraulic cylinder or a pneumatic cylinder, or it may include a motor that outputs rotary motion. When the power mechanism 12 includes a motor, it typically also includes gears and a limiting mechanism (such as a limiting groove) to convert the rotary motion output by the motor into linear motion through the cooperation of the gears and the limiting mechanism; or, the power mechanism 12 may also include a rack to convert the rotary motion output by the motor into linear motion.

[0054] In this application, the main body portion 131 on each massage head 13a may be two, three, four or five, etc. Any two adjacent main body portions 131 are connected by an elastic connecting portion 132. Correspondingly, the elastic connecting portion 132 on each massage head 13a may be one, two, three or four, etc.

[0055] For example, such as Figure 4 As shown, each massage head 13a includes three main body portions 131 and two elastic connecting portions 132. The three main body portions 131 include a first main body portion 131a and a second main body portion 131b and a third main body portion 131c symmetrically arranged about the first main body portion 131a. The two elastic connecting portions 132 include a first elastic connecting portion 1321 and a second elastic connecting portion 1322. The first elastic connecting portion 1321 is connected between the first main body portion 131a and the second main body portion 131b, and the second elastic connecting portion 1322 is connected between the first main body portion 131a and the third elastic connecting portion 132.

[0056] Since the side profile of the human waist is roughly C-shaped, the massage head 13a includes three main body parts 131 and two elastic connecting parts 132. The second main body part 131b and the third main body part 131c are symmetrically arranged about the first main body part 131a. The first elastic connecting part 1321 connects the first main body part 131a and the second main body part 131b, and the second elastic connecting part 1322 connects the first main body part 131a and the third elastic connecting part 132. Therefore, when the massage mechanism 10 of this application is worn on the human waist via the waistband body, the first main body part 131a abuts against the middle of the waist, while the second main body part 131b and the third main body part 131c abut against the upper and lower parts of the waist, respectively. The main body 131a is subjected to the force from the middle of the waist, while the second main body 131b and the third main body 131c are subjected to the forces from the upper and lower parts of the waist, respectively. This causes the second main body 131b and the third main body 131c to float with the first main body 131a as the fulcrum. Consequently, the second main body 131b and the third main body 131c bend towards the skin-proximity side of the housing 11, allowing the massage head 13a to better adapt to the shape of the waist and better conform to the curve of the human waist. This further enhances the floating and skin-contact ability of the massage head 13a, giving it better conformal deformation capabilities and allowing the massage head 13a to better fit the human waist, resulting in a better massage effect and further improving the user's massage comfort.

[0057] In this application, the material of the elastic connection part 132 may be, but is not limited to, silicone, plastic, rubber, foam, sponge, etc.

[0058] As an optional embodiment, the elastic connecting part 132 is a flexible colloid, and the elastic connecting part 132 and multiple main body parts 131 are integrally formed. The elastic connecting part 132 and the main body parts 131 of the massage component 13 adopt an integrally formed structure. The integrally formed elastic connecting part 132 and the main body parts 131 have strong connection strength, thereby ensuring good connectivity between the elastic connecting part 132 and the main body parts 131. This ensures the deformation performance of the elastic connecting part 132 when the main body parts 131 are subjected to force, allowing the main body parts 131 to float better, so that the main body parts 131 can float to conform to the waist, thereby further improving the floating and skin-fitting ability of the massage head 13a. The flexible colloid can be flexible silicone, flexible plastic, or other flexible materials.

[0059] As another alternative embodiment, the elastic connecting portion 132 and the main body portion 131 are connected by a threaded component or a snap-fit ​​component. The elastic connecting portion 132 and the main body portion 131 of the massage member 13 are fixedly connected by a threaded component or snap-fit ​​component, thereby ensuring the deformation performance of the elastic connecting portion 132 when the main body portion 131 is subjected to force, so that the main body portion 131 can float to conform to the waist. The threaded component can be a screw or bolt, etc.

[0060] As one embodiment, each main body 131 can be made of a rigid material, and along the direction in which the massage member 13 protrudes relative to the housing 11, for example, Figure 3 In the upward direction, the skin-proximal surface of each main body 131 is higher than the skin-proximal surface of the elastic connecting part 132. By setting the main body 131 of the massage head 13a to a rigid structure and making the skin-proximal surface of the main body 131 higher than the skin-proximal surface of the elastic connecting part 132, the part of the massage head 13a that contacts the waist has a certain degree of rigidity, so as to ensure the massage strength of the massage head 13a on the waist, thereby ensuring that the massage mechanism 10 has a better massage feel; at the same time, it can reduce the contact friction between the elastic connecting part 132 and the waist, reduce the resistance of the waist to the deformation of the elastic connecting part 132, facilitate the elastic deformation of the elastic connecting part 132, and thus facilitate the floating of the main body 131 to conform to the waist.

[0061] As one example, such as Figure 3 As shown, the elastic connecting part 132 can be a plate-like structure extending along the width direction f5 of the housing 11. The side of the elastic connecting part 132 facing the housing 11 is connected to the power mechanism. Multiple main body parts 131 are disposed on the side of the elastic connecting part 132 facing away from the housing 11, and each of the multiple main body parts 131 is configured as an arc-shaped protrusion protruding from the elastic connecting part 132 in a direction away from the housing 11. In this way, the arc-shaped protrusion can act like human fingers, allowing the massage head 13a to mimic the pinching and massaging action of a human hand on the waist. This massage action is comfortable, and the massage method is more in line with the symmetrical characteristics of the muscles and structures on both sides of the human lumbar spine, better meeting the user's waist massage needs.

[0062] As one example, such as Figure 5As shown, each main body 131 is fitted with a flexible rubber sleeve 14 around its outer periphery. The flexible rubber sleeve 14 is connected to the main body 131 and / or the elastic connecting part 132. Fitting the flexible rubber sleeve 14 onto the main body 131 increases the surface softness of the main body 131, much like a human finger. That is, the main body 131 is similar to the bone of a finger, while the flexible rubber sleeve 14 is similar to the flesh surrounding the finger bone. This allows the massage head 13a to better mimic the pinching and massaging motions of a human hand on the waist. It possesses both sufficient firmness to ensure the massage intensity of the massage head 13a and sufficient softness to ensure massage comfort, thus making it more comfortable to wear and improving the user's massage comfort.

[0063] Optionally, the flexible sleeve 14 may be made of, but is not limited to, silicone, plastic or rubber.

[0064] As one embodiment, a slot (not shown) may be formed on the outer peripheral surface of the main body 131, and the edge of the flexible sleeve 14 may be bent toward the main body 131 to form a snap-fit ​​portion (not shown). The snap-fit ​​portion is interference-fitted into the slot to restrict the flexible sleeve 14 from detaching from the main body 131. This allows the flexible sleeve 14 to use its own elasticity to fix the snap-fit ​​portion in the slot, thus preventing the flexible sleeve 14 from detaching from the slot and avoiding detachment from the main body 131. This fixing method, combined with the flexible material's deformable design, allows the snap-fit ​​portion to be interference-fitted into the slot, resulting in better connection stability between the flexible sleeve 14 and the main body 131. Furthermore, the fixing method is relatively simple and easy to implement.

[0065] Please see Figure 6 and Figure 7In one embodiment, there are at least two adjacent massage heads 13a, namely a first sub-massage head 13a1 and a second sub-massage head 13a2. The sides of the first sub-massage head 13a1 and the second sub-massage head 13a2 that are close to each other are both configured as the first side 13a3, and the sides of the first sub-massage head 13a1 and the second sub-massage head 13a2 that are far from each other are both configured as the second side 13a4. In the width direction f5 of the housing 11, the width d1 of the first side 13a3 of the first sub-massage head 13a1 is smaller than the width d2 of the second side 13a4 of the first sub-massage head 13a1, and the width d3 of the first side 13a3 of the second sub-massage head 13a2 is smaller than the width d4 of the second side 13a4 of the second sub-massage head 13a2. In this way, when at least two adjacent massage heads 13a move closer to each other, they can provide a massage sensation in the same massage area where the contact area between the massage head 13a and the massage area gradually increases. At the same time, when the two adjacent massage heads 13a move further apart, they can provide a massage sensation in the same massage area where the contact area between the massage head 13a and the massage area gradually decreases. This can improve the massage effect of the massage mechanism 10.

[0066] As one embodiment, multiple massage heads 13a can be divided into two massage groups. The two massage groups are located on opposite sides of the power mechanism 12 along the length direction f4 of the housing 11. The number of massage heads 13a in each massage group is even, and two massage heads 13a in each massage group form a pair of massage heads 13a. Under the driving action of the power mechanism 12, the two massage heads 13a in the pair of massage heads 13a move closer or further apart from each other along the length direction f4 of the housing 11.

[0067] When the massage mechanism 10 of this application is worn on the waist, one of the two massage groups is located on the left side of the spine and the other on the right side. Because the two massage heads 13a on the left side can move closer or further apart along the length direction f4 under the drive of the power mechanism 12, they can provide a pinching massage effect on the erector spinae muscles on the left side of the spine. Similarly, because the two massage heads 13a on the right side can move closer or further apart along the length direction f4 under the drive of the power mechanism 12, they can provide a pinching massage effect on the erector spinae muscles on the right side of the spine. Thus, the two massage groups can mimic the pinching massage action of a human hand on the erector spinae muscles on both sides of the spine. This massage action is comfortable, and the massage method better conforms to the symmetrical characteristics of the erector spinae muscles and structures on both sides of the human lumbar spine, better meeting the user's waist massage needs.

[0068] It should be noted that in this application Figure 6 and Figure 7This application exemplifies the use of a pair of massage heads 13a spaced apart along the length f1 of the housing 11 in each group of massage heads 13a as an example, and does not limit each group of massage heads 13a to only one pair spaced apart along the length f1 of the housing 11. In other implementations of this application, each group of massage heads 13a may include two, three, or more pairs of massage heads 13a spaced apart along the length f1 of the housing 11. This application does not specifically limit this.

[0069] As one embodiment, when two adjacent massage heads 13a are brought close to each other to their minimum distance, the minimum distance L between the two adjacent massage heads 13a is greater than 10mm. Exemplarily, the minimum distance L between any two adjacent first massage heads 13a in the longitudinal direction f4 of the mechanism housing can be 10.1mm, 10.2mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. By controlling the minimum distance L between two adjacent massage heads 13a to be greater than 10mm, pinching of the skin can be avoided to prevent discomfort or pain, or even injury, thereby improving the comfort of massage use.

[0070] As one embodiment, the edges of adjacent massage heads 13a that are close to each other are covered with a flexible material (not shown). This flexible material can be, but is not limited to, soft silicone, rubber, plastic, foam, or sponge, etc. By covering the edges of adjacent massage heads 13a with a flexible material, these massage heads 13a have an elastic cushioning and restoring effect, deforming according to the curve of the massage position, allowing the massage heads 13a to better conform to the human body's contours and achieve a better massage effect; at the same time, it also avoids the massage heads 13a pressing hard against muscles and preventing pinching, reducing pain and discomfort during the massage process, thereby helping to improve the comfort of massage use.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the content of this specification should not be construed as a limitation of this application, and the protection scope of this application should be determined by the appended claims.
