Description

Technical Field

[0001] This invention relates to the field of massage technology, and more particularly to a massage mechanism and a waist massager. Background Technology

[0002] Standing or sitting for long periods can put a lot of pressure on the lower back. Without exercise to strengthen the lower back muscles, it can easily lead to lower back pain and strain. Lower back massage devices, which can be worn on the lower back to massage it and relax the lower back muscles, can relieve lower back fatigue to some extent. As a result, lower back massage devices are becoming increasingly popular among users.

[0003] However, the waist massage devices in related technologies usually only use simple pressing or pounding to achieve massage. Such waist massage devices can usually only press or pound the waist in one direction, resulting in poor massage effect and a weak massage experience. Summary of the Invention

[0004] This invention discloses a massage mechanism and a waist massager that can provide both pinching and pushing massage to the waist, thereby effectively improving the massage effect and enhancing the user's massage experience.

In the same massage head, along the preset direction, the first side is closer to the first end than the second side.

[0018] In at least one pair of adjacent massage heads, the first side of each massage head is provided with a protrusion that protrudes in a direction away from the first side, and / or the second side of each massage head is provided with a protrusion that protrudes in a direction away from the second side.

[0019] As an optional implementation, in an embodiment of the first aspect of the present invention, the direction from the housing to the massage head is configured as a first direction, and the direction perpendicular to the preset direction and the first direction is configured as a second direction, wherein the protrusion is a strip-shaped structure extending along the second direction.

[0020] 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, the two massage groups are respectively located on two opposite sides of the driving device in the preset direction, the number of massage heads in each massage group is even, and the 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 preset direction under the driving action of the driving device.

[0021] As an optional implementation, in an embodiment of the first aspect of the present invention, the direction from the housing to the massage head is configured as a first direction, and the direction perpendicular to the preset direction and the first direction is configured as a second direction.

[0046] 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.

[0047] 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.

[0048] 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 side may be referred to as a second side, and similarly, a second side may be referred to as a first side. Both the first side and the second side are sides, but they are not the same side.

[0049] 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.

[0050] 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.

[0051] 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 lumbar massagers have emerged. These massagers can be worn on the lower back via a belt, eliminating the need for handheld use. The massage heads on the massage mechanism automatically massage the lower back, thereby relieving lumbar fatigue and injury.

[0052] However, in the massage mechanism of the relevant technology, the massage head can usually only perform planar rotational movement in a plane parallel to the skin surface of the massage mechanism. Under this massage method, the massage head cannot pinch the muscles of the massage area, making it difficult to effectively massage the waist, resulting in an unsatisfactory massage effect, which is even worse than manual kneading massage by non-professionals.

[0053] In view of this, the present application provides a massage mechanism that can provide pinching massage and oblique pushing massage to the waist, thereby effectively improving the massage effect of the waist massager and enhancing the user's massage experience.

[0054] The technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0055] Please see Figure 1 , Figure 1 This is a structural schematic diagram from one side view of one implementation of the waist massager in this application. This application discloses a waist massager 100, which includes a massage mechanism 10 and a wearing piece 20. The massage mechanism 10 is connected to the wearing piece 20, which can be worn and fixed to the waist of a person. This allows the massage mechanism 10 to be worn on the waist via the wearing piece 20, freeing the user's hands when massaging the waist, thereby improving the convenience and comfort of using the waist massager 100.

[0056] An example, such as Figure 1 As shown, the wearable component 20 can be a single, elongated strip-shaped part with an extending direction, for example... Figure 1 In the left-right direction, the massage mechanism 10 is approximately positioned at the middle of the wearing piece 20 in its extending direction, and the massage mechanism 10 can be located inside or outside the wearing piece 20. The two ends of the wearing piece 20 in its extending direction can be connected by Velcro, D-rings, etc., to fix it to the waist of the human body.

[0057] Another example, such as Figure 2 As shown, the wearable device 20 may include a separate first waist belt 21 and a second waist belt 22, with a massage mechanism 10 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 in a preset direction (e.g., Figure 2 The first waist belt 21 and the second waist belt 22 are arranged in sequence in the left and right directions. Both of them are strip-shaped structures that extend along the preset arrangement direction. 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, etc. to fix it on the waist of the human body.

[0058] Please see Figure 3 The massage mechanism 10 provided in this application embodiment includes a housing 11, a drive device 12, and a plurality of massage heads 13.

[0059] The drive device 12 in this application is mounted on the housing 11. The drive device 12 can be located outside the housing 11 or inside the housing 11. When the drive device 12 is located inside the housing 11, a portion of the drive device 12 is exposed outside the housing 11 to facilitate connection between the drive device 12 and the multiple massage heads 13.

[0060] Optionally, the number of massage heads 13 in this application can be two, three, four, five, six, etc. It is understood that the number of massage heads 13 can be determined according to actual needs, and this application does not impose specific limitations. It should be noted that, as shown in this application... Figures 1 to 4 In this application, only two massage heads 13 are used as examples for illustrative purposes, and the following are shown in the illustration. Figures 4 to 9 This application uses four massage heads 13 as an example for illustration only, and does not limit the number of massage heads 13 to only two or four. In other implementations of this application, the number of massage heads 13 may also be three, five, six, eight, etc. This application does not make any specific limitation in this regard.

[0061] Furthermore, in this application, multiple massage heads 13 are arranged at intervals along a preset direction f1 on the skin-proximity surface of the housing 11 to avoid the housing 11 obstructing the multiple massage heads 13, thereby facilitating contact between the multiple massage heads 13 and the human waist for massage. Each massage head 13 is connected to a drive device 12, so that under the drive of the drive device 12, adjacent massage heads 13 can move closer to or further away from each other in the preset direction f1. When adjacent massage heads 13 move closer to each other, they can provide a pinching massage effect on the waist, mimicking the pinching massage effect of a human hand on the waist, making the massage effect close to that of a professional manual kneading massage, thus enhancing the massage effect.

[0062] When the wearable component is an integral long strip, the preset direction f1 can be extended along the extension direction of the wearable component; and when the wearable component includes a first waist belt and a second waist belt that are separately arranged, the preset direction f1 can be extended along the preset arrangement direction of the first waist belt, the massage mechanism 10 and the second waist belt.

[0063] Please see Figure 4 In this application, at least two adjacent massage heads 13 each include a base 131 connected to the drive device 12 and an upper end portion 132 extending from the base 131 in a direction away from the housing 11. In at least two adjacent massage heads 13, along a preset direction f1, the distance between the nearest ends of the two bases 131 is L1, and the distance between the nearest ends of the two upper end portions 132 is L2, where L2 > L1.

[0064] In the above design, by using the drive device 12 to drive two adjacent massage heads 13 to move towards each other or away from each other, when the two adjacent massage heads 13 move towards each other, they can provide a pinching massage effect on the waist, mimicking the pinching massage effect of a human hand on the waist. This makes the massage effect close to that of a professional manual kneading massage. At the same time, by making the distance L2 between the nearest ends of the upper ends 132 of at least one pair of adjacent massage heads 13 greater than the distance L1 between the nearest ends of the bases 131 of the two adjacent massage heads 13, when the two adjacent massage heads 13 move closer to each other to act on the waist, they can provide a mimicking effect of a human palm pushing and massaging the waist at an angle. Thus, when the two adjacent massage heads 13 move closer to each other, they can provide a pinching massage effect on the muscles on both sides of the waist, which can improve the soothing effect on the waist and greatly improve the user experience and the massage effect of the waist massager.

[0065] Alternatively, it can be as follows Figure 4 and Figure 5 As shown, the distance L2 between the nearest ends of the upper ends 132 of any two adjacent massage heads 13 is greater than the distance L1 between the nearest ends of the bases 131 of the two adjacent massage heads 13; alternatively, the distance L2 between the upper ends 132 of some adjacent massage heads 13 may be greater than the distance L1 between the bases 131 of the two adjacent massage heads 13, for example, as Figure 6 and Figure 7 As shown, the distance L2 between the nearest ends of the upper ends 132 of two adjacent massage heads 13 is greater than the distance L1 between the nearest ends of the bases 131 of the two adjacent massage heads 13.

[0066] In one exemplary embodiment, the massage head 13 can be driven by the drive device 12 to move linearly along a preset direction f1, so that two adjacent massage heads 13 can move closer to or further away from each other along the preset direction f1. In this exemplary embodiment, the drive device 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 drive device 12 includes a motor that outputs rotary motion, 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 drive device 12 may also include a rack to convert the rotary motion output by the motor into linear motion.

[0067] In another exemplary embodiment, the massage head 13 can be driven by the drive device 12 to swing at least along a preset direction f1, so that two adjacent massage heads 13 can move closer to or further away from each other along the preset direction f1. In this exemplary embodiment, the drive device 12 may include a power mechanism and a swing mechanism. The swing mechanism is movably connected to the housing 11 and connected to the massage head 13. The power mechanism is connected to the swing mechanism and is used to drive the swing mechanism to swing relative to the housing 11 at least along the preset direction f1, thereby causing the massage head 13 to swing at least along the preset direction f1, and thus allowing two adjacent massage heads 13 to move closer to or further away from each other along the preset direction f1. The power mechanism may include a hydraulic cylinder, a pneumatic cylinder, or other mechanism that outputs linear motion, or it may include a motor that outputs rotary motion.

[0068] In this application, for ease of description, the direction from the housing 11 to the massage head 13 is designated as the first direction f2, and the direction perpendicular to the preset direction f1 and the first direction f2 is designated as the second direction f3. It is understood that the above configuration definitions are merely limitations made for the purpose of describing this application and should not be used to limit the scope of protection of this application.

[0069] Please see Figure 6 and Figure 7 The housing 11 in this application has a first end 11a and a second end 11b opposite to each other in a preset direction f1. Each massage head 13 has a first side 133 and a second side 134 opposite to each other in a preset direction f1. In the same massage head 13, the first side 133 is closer to the first end 11a than the second side 134 in the preset direction f1. In the multiple massage heads 13, the first side 133 and the second side 134 are arranged alternately in sequence. In at least one pair of adjacent massage heads 13, along a preset direction f1, the massage head 13 closer to the first end 11a is configured as the first sub-massage head 13a, and the massage head 13 closer to the second end 11b is configured as the second sub-massage head 13b. In a first direction f2, the second side surface 134 of the first sub-massage head 13a may be gradually inclined from its side near the housing 11 toward the direction away from the second sub-massage head 13b, and / or, the first side surface 133 of the second sub-massage head 13b may be gradually inclined from its side near the housing 11 toward the direction away from the first sub-massage head 13a, so that the distance L2 between the nearest ends of the upper ends 132 of the first sub-massage head 13a and the second sub-massage head 13b is greater than the distance L1 between the nearest ends of the bases 131 of the first sub-massage head 13a and the second sub-massage head 13b.

[0070] As one embodiment, in at least one pair of adjacent massage heads 13, the adjacent first side 133 and second side 134 are planar, for example, both adjacent first side 133 and second side 134 are inclined planes. Since the surface of the human palm is roughly planar, designing at least one pair of adjacent first side 133 and second side 134 as planar allows at least one pair of adjacent massage heads 13 to better mimic the oblique pushing massage motion of the human palm on the waist. This massage motion is comfortable, and the massage method can better meet the user's needs for waist massage.

[0071] Optionally, the plane is covered with a flexible material (not shown), that is, in at least one pair of adjacent massage heads 13, the adjacent first side 133 and second side 134 are covered with a flexible material. By covering the planar first side 133 and second side 134 with a flexible material, the oblique pushing and pinching massage action of the human palm on the waist can be imitated, while further imitating the softness of the human palm surface. This avoids the massage head 13 pressing hard against the muscles and avoids pinching the flesh, reducing pain and discomfort during the massage process, thus making the massage more comfortable, improving the comfort of oblique pushing massage, and enhancing the user's massage comfort.

[0072] As one example, combined with Figures 7 to 9 As shown, a protrusion 135 protrudes from the plane in a direction away from the plane. By providing the protrusion 135 on the first side 133 and the second side 134, which are designed as planes, the protrusion can be better embedded in the skin during oblique massage, so that at least one adjacent massage head 13 can lift the muscles during the movement, thereby enhancing the tactile richness of the massage when at least one adjacent massage head 13 is performing oblique massage and improving the massage effect.

[0073] Optionally, the protrusion 135 is a strip-shaped structure extending along the second direction f3. By designing the protrusion 135 as a strip extending along the second direction f3, when at least one adjacent massage head 13 performs an oblique pushing massage on the waist, the strip-shaped protrusion 135 can play the role of pushing and scraping the massage area, thus further enhancing the massage effect.

[0074] As one example, such as Figure 7As shown, in at least one pair of adjacent massage heads 13, along the preset direction f1, the distance between the farthest ends of the two bases 131 is L3, and the distance between the farthest ends of the two upper ends 132 is L4, where L4 < L3. When the relationship defined by the above formula is satisfied, during the movement of at least one pair of adjacent massage heads 13 moving away from each other, the first side 133 of the massage head 13 closer to the first end 11a and the second side 134 of the massage head 13 closer to the second end 11b can also play the role of mimicking the effect of the human palm to perform oblique pushing massage on the massage area, thereby improving the massage effect of the massage mechanism 10.

[0075] Alternatively, in some alternative embodiments, L4 = L2.

[0076] For example, in at least two adjacent massage heads 13, along a preset direction f1, the massage head 13 closer to the first end 11a is configured as the first sub-massage head 13a, and the massage head 13 closer to the second end 11b is configured as the second sub-massage head 13b. In the first direction f2, the first side surface 133 of the first sub-massage head 13a may be gradually inclined from its side near the housing 11 toward the direction near the second sub-massage head 13b, and / or, the second side surface 134 of the second sub-massage head 13b may be gradually inclined from its side near the housing 11 toward the direction near the first sub-massage head 13b. The direction of 13a is gradually tilted so that the distance L4 between the farthest ends 132 of the upper parts 132 of the first sub-massage head 13a and the second sub-massage head 13b is less than the distance L3 between the farthest ends 131 of the bases 131 of the first sub-massage head 13a and the second sub-massage head 13b. Therefore, even when the first sub-massage head 13a and the second sub-massage head 13b are moving away from each other, the first side 133 of the first sub-massage head 13a and the second side 134 of the second sub-massage head 13b can still mimic the effect of a human palm pushing the massage area at an angle, thus enhancing the massage effect of the massage mechanism 10. This ensures that whether the first sub-massage head 13a and the second sub-massage head 13b are close to each other or moving away from each other, the first sub-massage head 13a and the second sub-massage head 13b can mimic the effect of a human palm pushing the massage area at an angle, effectively enhancing the massage effect of the massage mechanism 10.

[0077] As one embodiment, in at least two adjacent massage heads 13, the first side 133 and the second side 134 of each massage head 13 are planar, and / or the first side 133 and the second side 134 of each massage head 13 are covered with a flexible material.

[0078] Since the surface of the human palm is roughly flat, the first side 133 and the second side 134 of each of at least two adjacent massage heads 13 are set to be flat. In this way, when at least two adjacent massage heads 13 are close to each other, the two adjacent massage heads 13 can better imitate the oblique pushing massage action of the human palm on the waist, and when the two adjacent massage heads 13 are far apart, the two adjacent massage heads 13 can also better imitate the oblique pushing massage action of the human palm on the waist. The above massage action is comfortable and the massage method can better meet the user's needs for waist massage.

[0079] By covering the first side 133 and the second side 134 of each of at least two adjacent massage heads 13 with a flexible material, it is possible to mimic the oblique pushing massage action of the human palm on the waist, while further mimicking the softness of the human palm surface. Whether the two adjacent massage heads 13 are close to each other or far apart, it can avoid the first side 133 and the second side 134 from pressing hard against the muscles and avoid pinching the flesh, reducing the pain and discomfort during the massage process, thus making the massage more comfortable, improving the comfort of oblique pushing massage, and enhancing the user's massage comfort.

[0080] As one example, combined with Figure 10 , Figure 11 and Figure 12 As shown, in at least one pair of adjacent massage heads 13, each massage head 13 has a first side 133 with a protrusion 135 protruding in a direction away from the first side 133, and / or, each massage head 13 has a second side 134 with a protrusion 135 protruding in a direction away from the second side 134.

[0081] By providing protrusions 135 on the first side 133 and the second side 134 of each of at least two adjacent massage heads 13, they can be better embedded in the skin during oblique push massage. This allows the two adjacent massage heads 13 to lift the muscles during movement, whether they are close to each other or far apart, thereby enhancing the tactile richness of the massage and improving the massage effect.

[0082] Optionally, the protrusion 135 is a strip-shaped structure extending along the second direction f3. By designing the protrusion 135 as a strip extending along the second direction f3, when the two adjacent massage heads 13 perform oblique pushing massage on the waist, the strip-shaped protrusion 135 can play the role of pushing and scraping the massage area, thus further enhancing the massage effect.

[0083] As one embodiment, multiple massage heads 13 are divided into two massage groups, which are located on opposite sides of the driving device 12 in a preset direction f1. Each massage group contains an even number of massage heads 13, and two massage heads 13 in each group form a pair. Under the driving action of the driving device 12, the two massage heads 13 in a pair move closer to or further away from each other along the preset direction f1. For example, as... Figure 12 As shown, there are four massage heads 13, located in... Figure 12 The two massage heads 13 on the left side of the middle form a pair of massage heads 13, while the one located on the left side of the middle forms a pair of massage heads 13. Figure 12 The two massage heads 13 on the right side form a pair of massage heads 13.

[0084] When the massage mechanism 10 of this application is worn on the waist, one massage group is located on the left side of the spine and the other massage group is located on the right side of the spine. Since the two massage heads 13 on the left side can move closer or further apart from each other along a preset direction f1 under the driving action of the driving device 12, they can exert an oblique pushing and pinching massage effect on the erector spinae muscles on the left side of the spine. At the same time, since the two massage heads 13 on the right side can move closer or further apart from each other along a preset direction f1 under the driving action of the driving device 12, they can exert an oblique pushing and pinching massage effect on the erector spinae muscles on the right side of the spine. In this way, the two massage groups on the left and right sides can imitate the oblique pushing and pinching massage action of the human hand on the erector spinae muscles on the left and right sides of the spine respectively. This massage action is comfortable and the massage method is more in line with the symmetrical characteristics of the erector spinae muscles and structures on the left and right sides of the human lumbar spine, better meeting the user's waist massage needs.

[0085] As one example, such as Figure 12 As shown, each massage head 13 is a strip-shaped structure extending along the second direction f3, and the length L of each massage head 13 in the second direction f3 is 5cm-15cm. For example, the length L of each massage head 13 in the second direction f3 is 5cm, 5.5cm, 6cm, 6.5cm, 7cm, 7.5cm, 8cm, 9cm, 10cm, 11cm, 12cm, 12.5cm, 13cm, 13.5cm, 14cm, 14.5cm, or 15cm, etc. Setting the length range of each massage head 13 to 5cm-15cm is close to the width of a human palm, thus better mimicking the effect of a diagonal massage by the palm.

[0086] In this application, for ease of description, the plane perpendicular to the second direction f3 is configured as the first plane. It is understood that the above configuration definition is merely a limitation for the purpose of describing this application and should not be used to limit the scope of protection of this application.

[0087] As one example, such as Figure 13As shown, in at least one pair of adjacent massage heads 13, the cross-sectional profile of each massage head 13 cut by the first plane is triangular, the base of the triangle is configured as the cross-sectional profile of the base 131 facing the bottom surface of the housing 11 cut by the first plane, and the triangle is an acute triangle with rounded transitions at the three included angles of the triangle.

[0088] Each massage head 13 has a triangular cross-sectional profile obtained by the plane perpendicular to the second direction f3. This provides stable support for the massage head 13 while it is performing an oblique push massage on the waist, thus improving the stability of the massage. At the same time, the three corners of the triangle are rounded to simulate the smooth transition of the edge of the human palm, avoiding the formation of sharp corners and reducing pain and discomfort during the massage process, thereby improving the comfort of the massage.

[0089] 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.

[0090] 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.
