Description

Active massage module and massage device including the same

[0001] The present invention relates to an active massage module and a massage device including the same, and more particularly, to an active massage module that performs active up-and-down movements in real time according to the user's body shape using an elastic member, and a massage device including the same.

[0002] Recently, various types of massage devices have become widespread. In particular, bed-type massage devices are becoming more widespread for user convenience and relaxation.

[0003] These massage devices have a massage module that includes acupressure elements that apply pressure to the user's body. These massage modules are typically arranged in parallel with two acupressure elements with a space between them so that the user's spine is centered.

[0004] So, when the user lies on the bed, the massage module moves along the user's spine, repeatedly raising and lowering each acupressure member according to the shape of the user's back or spine, thereby providing a more accurate and sophisticated massage effect to the user's back and spine area.

[0005] In this case, the massage module uses a motor to raise or lower the acupressure element. Specifically, the rotation of the motor is used to control the height at which the acupressure element is raised or lowered. However, the complexity of the mechanical structure connecting the motor and the acupressure element, coupled with design difficulties, poses a significant challenge in the time and cost involved in manufacturing the massage device.

[0006] Additionally, there was a problem that the vibration of the massage module reduced the durability of the components inside the module and did not provide a comfortable experience to the user.

[0007] Moreover, the massage module must move up and down in real time to fit the user's body shape, but when the motor is used to perform the up and down movement, the response speed is slow, which is a problem in that it cannot move up and down quickly to fit the shape of the user's back or spine.

[0008] The present invention aims to solve the above-mentioned problems.

[0009] The purpose of the present invention is to provide an active massage module including a pad that can move up and down in real time according to the user's body shape without relying on a motor, and a massage device including the same.

[0036] Hereinafter, a massage device including an active massage module according to one embodiment of the present invention will be described with reference to FIG. 1.

[0037] FIG. 1 is a drawing showing a massage device (100) including an active massage module according to one embodiment of the present invention.

[0038] A massage device (100) including an active massage module according to one embodiment of the present invention includes a housing (110), a bed (120), at least two massage modules (1100, 1200), and a moving part (101).

[0039] The housing (110) has a receiving space formed inside.

[0040] The bed (120) can be slidably connected to the upper part of the housing (110). The bed (120) can be slidably moved on the upper part of the housing (110) according to the height of the user who wants to use the massage device (100), and can have the effect of extending the overall length of the massage device (100).

[0041] Additionally, the moving part (101) can move the massage modules (1100, 1200) in the longitudinal direction of the housing or in the direction in which the bed slides.

[0042] For this purpose, the moving part (101) may include a driving motor (130), a driving band (140), a guide rail (150), a driving chain (160), and a driving gear (170), as shown in FIG. 1.

[0043] The driving motor (130) generates a driving force that enables the massage modules (1100, 1200) to move and may be a commonly used electric motor type.

[0044] The drive band (140) is connected to the drive motor (130) and the drive gear (170) on both sides, respectively, and transmits the driving force, i.e., the rotational force, generated from the drive motor (130) to the drive gear (170).

[0045] At least two guide rails (150) may be installed inside the housing (110) to guide the movement direction of the massage modules (1100, 1200). As shown in FIG. 1, one may be installed on the right side of the second massage module (1200), and although it is difficult to confirm in FIG. 1, one may also be installed on the left side of the first massage module (1100). However, this is not limited thereto, and at least two guide rails may be installed on the bottom surface of the housing.

[0046] The drive chain (160) is coupled to the side of the massage modules (1100, 1200) and can adjust the distance that the housing of the massage modules (1100, 1200) moves in the longitudinal direction or in the direction in which the bed slides.

[0047] The drive gear (170) can also control the movement speed of the massage modules (1100, 1200), and converts the rotational force generated by the drive motor (130) into linear motion energy through the drive chain (160) so that the massage modules (1100, 1200) can move forward and backward along the length direction of the housing (110).

[0048] Meanwhile, the moving part (101) and the massage modules (1100, 1200) are all arranged inside the housing (110), as illustrated in FIG. 1. In particular, the massage modules (1100, 1200) are configured to partially protrude from the upper surface of the housing (110) or the bed (120) when the massage device user lies down on the bed (120), thereby applying pressure to the muscles of the user's back or spine.

[0049] An active massage module according to one embodiment of the present invention will be described with reference to FIGS. 2 to 6.

[0050] FIG. 2 is a drawing showing one active massage module according to one embodiment of the present invention, and FIG. 3 is a drawing showing a detailed configuration of one active massage module according to one embodiment of the present invention, expanded vertically. FIG. 4 is a drawing showing a detailed configuration of a pad and a pad frame part according to one embodiment of the present invention, and FIG. 5 is a drawing showing a plan view of part V shown in FIG. 4. In addition, FIG. 6 is a drawing showing a plan view of part VI shown in FIG. 4.

[0051] First, referring to FIG. 2, it can be seen that an active massage module (1100) according to one embodiment of the present invention is configured such that a pad (11110) and a pad frame (11120) are coupled to the upper surface of at least one height adjustment part (11200), and a lower surface of the height adjustment part (11200) is coupled to a first base frame (11300).

[0052] In addition, the rotation motor part (11400) is mounted on the lower part of the first base frame (11300), and the support frame (11500) is configured to be positioned between the first base frame (11300) and the pad frame (11120).

[0053] Meanwhile, a second base frame (11600) can be coupled to the lower surface of the first base frame (11300). The second base frame (11600) can support a rotation motor unit (11400) and various PCBs or circuit boards can be mounted thereon.

[0054] Additionally, at least one anti-vibration member (11701, 11702) may be placed between the first base frame (11300) and the second base frame (11600).

[0055] These anti-vibration members (11701, 11702) may have soundproofing and anti-vibration functions to prevent noise or a decrease in durability of the active massage module (1100) by affecting the mechanical configuration and connection, such as by causing interference or friction between the first base frame (11300) and the second base frame (11600) due to vibrations generated by the rotation of the rotation motor unit (11400) and the rotation shaft (11410).

[0056] Therefore, it is preferable that the vibration-proof members (11701, 11702) be formed of rubber material.

[0057] In addition, as shown in FIG. 3, the vibration-proof members (11701, 11702) have a shape similar to an inverted bowl, and are arranged so that the side with a wider cross-sectional area contacts the second base frame (11600) and the side with a narrower cross-sectional area contacts the first base frame (11300), which is preferable for minimizing vibration and noise generated by the rotation of the rotation motor unit (11400) and the rotation shaft (11410).

[0058] Referring to FIG. 3, one active massage module (1100) according to one embodiment of the present invention may include a cover (11010), a pad (11110), a pad frame (11120), a first height adjustment unit (11201), a second height adjustment unit (11202), a first base frame (11300), a connecting shaft (11130), a rotation motor unit (11400), and a support frame (11500).

[0059] As shown in FIG. 3, the cover (11010) has a space formed therein that can accommodate a pad (11110) and a pad frame (11120), and is formed so that the pad (11110) and the pad frame (11120) can protrude upward.

[0060] In addition, the cover (11010) is preferably formed of a rubber material to reduce vibrations or noises that may occur when the pad (11110) and pad frame (11120) move up and down.

[0061] The pad (11110) and pad frame (11120) can vibrate left, right, forward, and backward to some extent in addition to the up and down movement. In order to protect other parts from the shock and friction generated from the vibrational movement of the pad (11110) and pad frame (11120) and to suppress noise generated from the vibrational movement, it is preferable that the cover (11010) itself be made of a rubber material.

[0062] The pad (11110) is a part that can come into direct contact with the user's back or spine, and is a part that applies pressure to the user's body through the up-and-down movement of the height adjustment part (11200) described later.

[0063] Meanwhile, referring to FIG. 4, the upper part of the pad frame (11120) is connected to the lower part of the pad (11110), and the lower part or side of the pad frame (11120) is connected to the height adjustment part (11200). The upper part of the pad frame (11120) can be divided into a first pad frame (11121), and the lower part of the pad frame (11120) can be divided into a second pad frame (11122).

[0064] The first pad frame (11121) and the second pad frame (11122) can be assembled and fixedly connected and configured to move together.

[0065] The first pad frame (11121) may further include a first protruding connecting portion (11123) formed on the left side of the first pad frame (11121) and a second protruding connecting portion (11124) formed on the right side, as illustrated in FIG. 4.

[0066] In this case, the first height adjustment part (11201) can be connected to the lower part of the first protruding connection part (11123), and the second height adjustment part (11202) can be connected to the lower part of the second protruding connection part (11124).

[0067] Meanwhile, the first protruding connecting portion (11123) may be provided with a durability improvement member. For example, in the first protruding connecting portion (11123), a durability improvement member may be provided on the surface where the first protruding connecting portion (11123) and the first height adjustment portion (11201) come into contact.

[0068] Additionally, a durability improvement member may be provided on the second protruding connection portion (11124). For example, in the second protruding connection portion (11124), a durability improvement member may be provided on the surface where the second protruding connection portion (11124) and the second height adjustment portion (11202) come into contact.

[0069] The durability-enhancing member may be composed of a tactile guide material. Furthermore, the durability-enhancing member may be comprised of various materials, such as metal or special reinforced plastic, to enhance durability and reduce friction.

[0070] This is to reduce or prevent friction damage caused by the first protruding connection part (11123) and the second protruding connection part (11124) being connected to the first height adjustment part (11201) and the second height adjustment part (11202), respectively.

[0071] The first protruding connection part (11123) and the second protruding connection part (11124) are connected to the first height adjustment part (11201) and the second height adjustment part (11202), respectively. As will be described later, the second pad frame (11122) vibrates due to the eccentric central protrusion (11125), so the first protruding connection part (11123) and the second protruding connection part (11124) formed integrally with the second pad frame (11122) can also vibrate. In this case, friction may occur at the portion where the first height adjustment part (11201) and the second height adjustment part (11202) are connected to the first protruding connection part (11123) and the second protruding connection part (11124). Therefore, a bearing made of a guide material or the like is attached or coated to the first protruding connection part (11123) and the second protruding connection part (11124).

[0072] Accordingly, when the first height adjustment unit (11201) and the second height adjustment unit (11202) move up and down, the first pad frame (11121) also moves up and down, and the pad (11110) on the upper surface of the first pad frame (11121) also moves up and down.

[0073] Continuing with reference to FIG. 4, the lower portion of the second pad frame (11122) is coupled to the upper surface of the connecting frame (11140).

[0074] The connecting frame (11140) includes a through hole (11141) that can accommodate the upper portion of the connecting shaft (11130), and as a result, the connecting shaft (11130) has the effect of being connected to the second pad frame (11122) due to the through hole (11141) formed in the connecting frame (11140).

[0075] Meanwhile, the planar shape of these through holes (11141) can be confirmed in detail in Fig. 5.

[0076] Referring to FIG. 5, the plane shape of the through hole (11141) formed in the center of the connecting frame (11140) is oval and has a size and width sufficient to accommodate the upper portion of the connecting shaft (11130).

[0077] However, the planar shape of the through hole (11141) is not necessarily limited to an ellipse, and may include a D-cut shape with one side of a circle cut off, an I-cut or T-cut shape with both sides of a circle cut off, a triangle, a square, or other polygonal shapes such as a pentagon, hexagon, or octagon.

[0078] Referring again to FIG. 4, the connecting shaft (11130) may be formed in two parts such that the upper part (11130a) has a larger area than the lower part (11130b). However, even if it is formed in two parts, the lower part (11130b) and the upper part (11130a), it may not be formed so that the two parts are separable.

[0079] A groove having a D-cut cross-sectional shape is formed inside the connecting shaft (11130) as shown in part 11130b of FIG. 4, and a rotary shaft (11410) to be described later is inserted into this groove.

[0080] Meanwhile, the planar shape of the upper portion (11130a) of the connecting shaft (11130) is oval as shown in part 11130a of FIG. 4, and this shape is formed in the same shape as the planar shape of the through hole (11141) described above.

[0081] However, the characteristic is that the width of the through hole (11141) is formed to be slightly larger than the width of the upper portion (11130a) of the connecting shaft (11130), so that the upper portion (11130a) of the connecting shaft (11130) can be inserted into the through hole (11141).

[0082] In addition, the reason why the upper portion (11130a) of the through hole (11141) and the connecting shaft (11130) are formed in an elliptical shape is that the connecting shaft (11130) also rotates or vibrates due to the rotation of the rotary shaft (11410) described later. At this time, the upper portion (11130a) of the connecting shaft (11130) must be formed in an elliptical shape to maximize the stress caused by contact with the through hole (11141), thereby preventing cracks from occurring in the through hole (11141) and enhancing the durability of the active massage module overall.

[0083] Referring again to FIG. 3, the rotary motor unit (11400) may further include a rotary shaft (11410) protruding upwards so as to be inserted and coupled into a groove having a D-cut cross-sectional shape formed in the connecting shaft (11130).

[0084] The cross-sectional shape of the upper surface (11411) of this rotating shaft is circular, and the rotating shaft (11410) having such a circular cross-sectional shape is inserted and connected into the groove of the connecting shaft (11130) having a D-cut cross-sectional shape, so that the connecting shaft (11130) can be rotated or vibrated according to the rotation of the motor of the rotating motor unit (11400).

[0085] To explain this process in more detail, when a rotary shaft (11410) having a circular cross-section shape is coupled to a groove having a D-cut cross-section shape inside a connecting shaft (11130) and the rotary shaft (11410) rotates by a rotational force generated from a rotating motor unit (11400), the connecting shaft (11130) rotates or vibrates due to a difference in the cross-section shape of the rotary shaft (11410) and the cross-section shape of the groove of the connecting shaft (11130).

[0086] Meanwhile, the support frame (11500) located between the rotation motor unit (11400) and the second pad frame (11122) has an upper surface in contact with the lower surface of the connecting shaft (11130), and the lower surface of the support frame (11500) is connected to the upper surface of the first base frame (11300). At this time, a hole through which the rotation shaft (11410) can pass is formed in the center.

[0087] The rotating shaft (11410) is connected to the connecting shaft (11130) by penetrating a hole formed in the center of the support frame (11500), so that the support frame (11500) prevents the rotating shaft (11410) from shaking due to vibrations occurring while rotating, and allows the rotating shaft (11410) to rotate while maintaining a constant rotating axis.

[0088] Ultimately, the support frame (11500) has the effect of preventing stress accumulation in the rotating shaft (11410) while enhancing the durability of the rotating shaft (11410).

[0089] Referring again to FIG. 4, the second pad frame (11122) further includes a central protrusion (11125) that protrudes upwardly convexly from the inner center, and the central protrusion (11125) is formed to protrude eccentrically from the center or centerline of the second pad frame (11122).

[0090] The fact that the central protrusion (11125) is formed eccentrically can be more accurately confirmed with reference to Fig. 6. Referring to Fig. 6, the central protrusion (11125) is formed eccentrically by moving a certain distance to the right from the center or exact center of the second pad frame (11122). However, it is not limited to being eccentric to the right, and it can also be formed eccentrically to the left, upper side, or lower side.

[0091] The reason why the central protrusion (11125) is formed eccentrically from the center or center of the second pad frame (11122) is to increase the size of the vibration generated when the second pad frame (11122) rotates due to the rotation of the connecting shaft (11130).

[0092] Meanwhile, a weighted portion (11126) is formed in the direction opposite to the direction in which the central protrusion (11125) is eccentric.

[0093] Referring to FIG. 6, the central protrusion (11125) is formed eccentrically by moving a certain distance to the right from the center or center of the second pad frame (11122), while the weighting portion (11126) is formed to contact the left end surface from the center or center of the second pad frame (11122).

[0094] The weighting member (11126) may also be generally referred to as a weight or a weight, and serves to add weight to the second pad frame (11122).

[0095] In addition, the weighting member (11126) adds weight to one side of the second pad frame (11122) when the second pad frame (11122) vibrates due to the eccentric configuration of the central protrusion (11125), thereby making the vibration width of the second pad frame (11122) constant. Therefore, the user can feel a stable feeling of use when using the massage device.

[0096] Hereinafter, a height adjustment unit (11200) according to an embodiment of the present invention will be described with reference to FIGS. 3 and 7. FIG. 3 is a drawing vertically unfolding a detailed configuration of one active massage module according to an embodiment of the present invention, and FIG. 7 is a cross-sectional view showing structural changes according to the driving state of a first height adjustment unit according to an embodiment of the present invention.

[0097] First, referring to FIG. 3, an embodiment can be seen in which two height adjusting parts, a first height adjusting part (11201) and a second height adjusting part (11202), are configured to adjust the protruding height of a pad (11110).

[0098] For convenience of explanation, the configuration of the first height adjustment unit (11201) is described as an example here.

[0099] The first height adjustment unit (11201) may include an adjustment shaft (11211), a stopper (11211a) formed integrally with the adjustment shaft (11211), a spring (11221), and a fixing bracket (11231). Meanwhile, since the configurations of the first height adjustment unit (11201) and the second height adjustment unit (11202) are the same, the second height adjustment unit (11202) may also include an adjustment shaft (11212), a stopper (11211a) formed integrally with the adjustment shaft (11211), a spring (11222), and a fixing bracket (11232).

[0100] The adjustment shaft (11211) actively moves up and down in real time by gravity and the elasticity of the spring (11221) according to the body shape of the user of the massage device, thereby adjusting the height of the first pad frame (11121).

[0101] Adjusting the height of the first pad frame (11121) means that the height of the pad (11110) coupled to the upper surface of the first pad frame (11121) is also adjusted, and ultimately, the up-and-down movement of the adjustment shaft (11211) is the same as adjusting the protruding height of the pad (11110).

[0102] As shown in FIGS. 3 and 7, the spring (11221) is coupled to the outside of the adjustment shaft (11211) so as to have the same central axis as the adjustment shaft (11211), and for this coupling, it is preferable that the diameter of the spring (11221) be larger than the diameter of the adjustment shaft (11211). However, the coupling structure of the spring (11221) and the adjustment shaft (11211) is not necessarily limited thereto.

[0103] The stopper (11211a) allows the adjustment shaft (11211) to move up and down within a certain range.

[0104] Referring to (a) of FIG. 7, the stopper (11211a) can be raised by the increasing force of the spring (11221) so that the adjusting shaft (11211) rises until it comes into contact with the fixed bracket (11232).

[0105] Conversely, referring to (b) of FIG. 7, when the pad (11110), the first pad frame (11121), and the second pad frame (11122) are pressed by the user's body shape to lower the adjustment shaft (11211), the stopper (11211a) can apply pressure to the spring (11221) to lower the adjustment shaft (11211) until it comes into contact with the first base frame (11300).

[0106] As shown in Fig. 7, the fixed bracket (11232) is fixedly connected to the first base frame (11300) via a screw or the like to limit the upward movement of the spring (11221), and prevents the upward movement of the stopper (11211a) so that the adjustment shaft (11211) can rise only to a certain height (h).

[0107] Hereinafter, with reference to FIG. 7, a method for adjusting the height of the first pad frame (11121) by the first height adjustment unit (11201) will be described.

[0108] Referring to (a) of Fig. 7, the first height adjustment part (11201) is in a state where the first height adjustment part (11201) protrudes toward the upper surface of the bed (120) and makes the height of the first pad frame (11121) the highest.

[0109] In this case, the user can generally view the massage device (100) as being in an idle state, and the first pad frame (11121) and the pad (11110) may be in the most protruding state.

[0110] At this time, the adjustment shaft (11211) of the first height adjustment unit (11201) is raised as high as possible, and the first protruding connection unit (11123) connected to the upper end of the adjustment shaft (11211) is pushed up, so that the first pad frame (11121) is raised.

[0111] On the other hand, referring to (b) of FIG. 7, the first height adjustment part (11201) is inserted into the housing (110) toward the lower surface of the bed (120), and the first height adjustment part (11201) makes the height of the first pad frame (11121) the lowest.

[0112] In this case, it can be generally viewed as an operation state in which the user uses the massage device (100), and the first pad frame (11121) and the pad (11110) may be inserted into the housing (110) due to the user's body shape and weight.

[0113] At this time, the adjustment shaft (11211) of the first height adjustment unit (11201) is lowered as much as possible, and the first protruding connection unit (11123) connected to the upper end of the adjustment shaft (11211) is made to be able to descend. Accordingly, the first pad frame (11121) is lowered.

[0114] In this way, the active massage module (1100) according to the present invention and the massage device (100) including the same can move up and down in real time according to the user's body shape without relying on a motor, so the structure is simplified, thereby reducing time and cost in production and manufacturing.

[0115] In addition, the active massage module (1100) according to the present invention has the advantage of having a simple yet efficient structure and thus its durability does not easily decrease even with repeated operations.

[0116] The above detailed description should not be construed as limiting in any respect, but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the scope of equivalents of the claims are intended to be included within the scope of the present invention.
