Description

Technical Field

[0001] This utility model relates to massage chair armrests and massage chairs. Background Technology

[0002] Existing massage chairs typically include control panels and other control components to allow users to switch between massage modes while seated in the chair.

[0003] However, in existing massage chairs, the control unit remains mounted on the upper surface of the armrest when not in use, which can easily obstruct the view or movement of the person receiving the massage. Utility Model Content

[0004] This utility model was made in view of the above-mentioned problems, and its purpose is to provide a massage chair armrest and a massage chair, so as to avoid the control parts on the upper surface of the armrest body from becoming obstacles to the view or movement of the person receiving treatment when not in use.

[0005] To achieve the above objectives, this utility model provides a massage chair armrest, comprising: an armrest body; a rotating body disposed on the upper surface of the armrest body and connected to the armrest body in a manner that allows it to rotate around a first axis and stand upright or lie down relative to the upper surface; and a driving mechanism that drives the rotating body to rotate, wherein when the rotating body lies down relative to the upper surface, the main body of the rotating body does not overlap with the driving mechanism when viewed from above.

[0006] According to the massage chair armrest of this utility model, the rotating body is connected to the armrest body in a manner that allows it to rotate around a first axis and stand upright or lie down relative to the upper surface of the armrest body. Therefore, when the rotating body is, for example, a control unit, by rotating the rotating body to lie down relative to the upper surface of the armrest body, it is possible to avoid the control unit or the like becoming an obstacle to the user's vision or movement when not in use. Furthermore, when the rotating body lies down relative to the upper surface of the armrest body, the main body of the rotating body does not overlap with the drive mechanism when viewed from above. Therefore, the space where the armrest body and the main body of the rotating body overlap when lying down can be fully utilized, for example, by providing a storage slot.

[0007] Furthermore, in the massage chair armrest of this utility model, the driving mechanism includes a connecting rod and a driving part. One end of the connecting rod is connected to the rotating body in a manner that allows it to rotate about a second axis parallel to the first axis. The driving part is connected to the other end of the connecting rod through a ball joint to drive the connecting rod to rotate.

[0008] According to the massage chair armrest of this utility model, the drive unit and the other end of the connecting rod are connected by a ball joint. Therefore, when the drive unit drives the connecting rod to rotate, jamming can be avoided.

[0009] Furthermore, in the massage chair armrest of this utility model, the driving part includes: a motor; a lead screw that extends in a direction intersecting the first axis and is driven to rotate by the motor; and a slider that is threadedly connected to the lead screw and connected to the other end of the connecting rod via the ball joint.

[0010] According to this utility model, the massage chair armrest utilizes a lead screw and slider mechanism to drive the connecting rod to rotate, which can reduce the design space of the drive unit to fit the limited space of the massage chair armrest; and the rotation action is electrically controlled by driving the connecting rod to rotate through a motor.

[0011] Furthermore, in the massage chair armrest of this utility model, the slider includes a first sliding member and a second sliding member, the first sliding member and the second sliding member are spliced ​​together to form a ball socket, and at least one of them is threadedly connected to the lead screw, and one end of the connecting rod is formed with a ball head that engages with the ball socket.

[0012] The massage chair armrest of this utility model allows for a more suitable size for the ball socket and ball head, thereby making the operation of the drive mechanism more stable and preventing it from loosening during operation.

[0013] Furthermore, in the massage chair armrest of this utility model, a code disk is integrally formed on the lead screw, and the drive unit also includes a detector that detects the starting position of the slider and the rotation of the code disk.

[0014] According to the present invention, the encoder and lead screw of the massage chair armrest are integrated, with good synchronization. Therefore, the detector can more accurately detect the rotation of the lead screw to obtain the movement stroke of the slider, thereby controlling the rotation of the rotating body more precisely. In addition, the integration of multiple components can reduce the size of the mechanism, thus adapting to the design requirements of the limited space of the massage chair armrest.

[0015] Furthermore, in the massage chair armrest of this utility model, a mounting base is fixed inside the armrest body, and the drive unit is supported on the mounting base.

[0016] According to the present invention, the massage chair armrest can support the drive unit on the mounting base and then fix it inside the armrest body, thus facilitating assembly; and by assembling the drive unit with the mounting base as a reference, assembly position errors are reduced; for example, the detection unit and the code disk are easier to align.

[0017] Furthermore, in the massage chair armrest of this utility model, the mounting base has: a fixing wall for fixing the motor; and a support wall for supporting the slider and restricting the slider's rotation.

[0018] According to the present invention, the massage chair armrest strengthens the structural strength of the drive mechanism by setting a support wall on the mounting base to support the slider.

[0019] Furthermore, in the massage chair armrest of this utility model, a storage groove is provided at the position of the armrest body below the rotating body for storing the rotating body when lying down.

[0020] According to the present invention, the armrest of the massage chair can be rotated to act as a cover for the storage compartment when the chair is reclined, so as to prevent dust from falling into the storage compartment.

[0021] Furthermore, in the massage chair armrest of this utility model, the rotating body is a control unit or a support seat.

[0022] Here, the support is, for example, a charging dock or a hand controller bracket.

[0023] Furthermore, in the massage chair armrest of this utility model, the rotating body has a flat plate portion, a rotating fulcrum portion, and a connecting ear portion. The rotating fulcrum portion is located near one end of the flat plate portion and is supported on the armrest body in a manner that allows it to rotate around the first axis. The connecting ear portion is located near one end of the flat plate portion and is connected to one end of the connecting rod in a manner that allows it to rotate around the second axis. When viewed from the side, the second axis is farther away from the flat plate portion than the first axis. When viewed from the side, the line connecting the first axis and the second axis is perpendicular to the flat plate portion.

[0024] According to the massage chair armrest of this utility model, when the rotating body is reclined, the rotation center of the rotating fulcrum and the rotation center of one end of the connecting rod are located at the same position in the front-back direction. Therefore, it can maximize the preservation that "the main body of the rotating body when reclining relative to the upper surface does not overlap with the drive mechanism when viewed from above".

[0025] In addition, to achieve the above objectives, this utility model provides a massage chair, including the massage chair armrests of any of the above-mentioned types. Attached Figure Description

[0073] Below, in conjunction with Figures 1 to 8 This invention describes a massage chair with armrests that utilize the embodiments of the present invention.

[0074] For ease of explanation, the orientation of the massage chair's structure is described using the perspective of the person receiving the massage while seated. For example, the front side (front view) of the person receiving the massage is referred to as "front" or "forefront," the back side (back view) as "back" or "rear," the upper side (head side) as "upper" or "above," the lower side (foot side) as "lower" or "below," the right side as "right" or "right side," and the left side as "left" or "left side."

[0075] (The overall structure of the massage chair)

[0076] like Figure 1 As shown, the massage chair 1 includes a base 10, a seat 20, a backrest 30, a leg support 40, and armrests 50. The base 10 is placed on the ground. The seat 20 is supported from below by the base 10. The backrest 30 extends backward and upward from the seat 20. The leg support 40 extends forward and downward from the seat 20. The armrests 50 are located on the left and right sides of the seat 20.

[0077] (Massage chair armrests)

[0078] like Figures 2 to 4 As shown, the massage chair armrest 50 includes an armrest body 51, a rotating body 52, and a drive mechanism 53. The rotating body 52 is disposed on the upper surface 5111 of the armrest body 51, and is capable of rotating around a first axis AX1 (see reference). Figure 5 In the example shown, (parallel to the left and right direction) rotates and stands upright relative to the upper surface 5111 (see reference). Figure 3 ) or lie down (see reference) Figure 2 The rotating body 52 is connected to the armrest body 51 in a manner that allows it to rotate. The drive mechanism 53 drives the rotating body 52 to rotate. When the rotating body 52 is lying down relative to the upper surface 51, it does not overlap with the drive mechanism 53 when viewed from above.

[0079] Here, as Figure 2 As shown, the rotating body 52 and the driving mechanism 53 are located on the left handrail body 51, but they can also be located on the right handrail body 51.

[0080] In addition, such as Figures 2 to 4 As shown, the handrail body 51 includes a long strip-shaped top plate 511 extending in the front-to-back direction. The top plate 511 has an upper surface 5111. A through hole 5112 is provided at the midpoint of the length direction of the top plate 511. The through hole 5112 penetrates the top plate 511 in the vertical direction. The sidewall of the through hole 5112 is provided with a groove that is recessed or penetrates along the rotation axis (i.e., the first axis AX1) of the rotating body 52.

[0081] In addition, such as Figures 2 to 4As shown, the rotating body 52 is disposed above the top plate 511. Furthermore, the rotating body 52 is located midway along the length of the top plate 511. When lying down, the rotating body 52 is stacked on top of the upper surface 5111 from above. Also, the rotating body 52 protrudes from the upper surface 5111 when lying down relative to it.

[0082] In addition, such as Figures 2 to 4 As shown, the main body of the drive mechanism 53 is located below the top plate 511 and at the rear end of the top plate 511 (in other possible embodiments, it may also be located on the side of the top plate 511).

[0083] In addition, such as Figure 4 As shown, a mounting base 54 is fixed inside the handrail body 51. The mounting base 54 supports the drive mechanism 53.

[0084] (Rotating body)

[0085] like Figures 2 to 5 As shown, the rotating body 52 is in the shape of a cuboid.

[0086] Here, as Figure 4 and Figure 5As shown, the rotating body 52 is the control unit, including a control terminal 521 and a bracket 522. The control terminal 521 is, for example, a hand controller. The bracket 522 has a flat plate portion 5221, a bent portion 5222, a pivot point portion 5223, and a connecting ear portion 5224. The flat plate portion 5221 has a generally rectangular planar shape and supports the back of the control terminal 521. The bent portion 5222 bends from both ends of the flat plate portion 5221 along the length direction toward the same side, clamping the control terminal 521 from both sides. The pivot point portion 5223 protrudes from near one end of the flat plate portion 5221 along the length direction toward the side opposite to the bent portion 5222, and a pair are provided at intervals along the width direction of the flat plate portion 5221 (in the illustrated example, consistent with the extension direction of the first axis AX1). The pivot point 5223 has a shaft portion centered on the rotation axis of the rotating body 52 (i.e., the first axis AX1), which is embedded in a slot in the side wall of the through hole 5112 of the top plate 511. The connecting ear 5224 protrudes from near one end of the flat plate 5221 in the longitudinal direction toward the side opposite to the bent portion 5222, and the protrusion is greater than the protrusion of the pivot point 5223 from the flat plate 5221. A pair of connecting ears 5224 are spaced apart in the width direction of the flat plate 5221, and are located between the pair of pivot points 5223 in the width direction of the flat plate 5221. The front end of the connecting ear 5224 has a through hole centered on the second axis AX2 described below. When viewed from the side (along the left-right direction), the center of the through hole of the connecting ear 5224 (corresponding to the rotation center of the second axis AX2 and one end of the connecting rod 531 described below) is farther from the plate portion 5221 than the rotation center of the rotation fulcrum portion 5223 (corresponding to the first axis AX1); and the line connecting the rotation center of the rotation fulcrum portion 5223 and the center of the through hole of the connecting ear 5224 is perpendicular to the plate portion 5221. Therefore, the connecting ear 5224 can adapt to the thickness of the top plate 511, and when the rotating body 52 is laid down, the rotation center of the rotation fulcrum portion 5223 and the center of the through hole of the connecting ear 5224 are located at the same position in the front-rear direction, so that the drive mechanism 53 can be completely placed on one side of the rotating body 52 (the rear side in the illustrated example).

[0087] (Drive mechanism)

[0088] like Figure 4 and Figure 5 As shown, the drive mechanism 53 includes a connecting rod 531 and a drive unit 532.

[0089] Here, as Figure 4 and Figure 5 As shown, connecting rod 531 passes through through hole 5112 in top plate 511. One end of connecting rod 531 is parallel to a second axis AX2 (refer to) that is parallel to the axis of rotation of rotating body 52 (i.e., the first axis AX1). Figure 5The connecting rod 531, located near the first axis AX1 but further away from the back of the flat plate 5221 than the first axis AX1, is connected to the rotating body 52 by means of rotation. The other end of the connecting rod 531 is connected to the drive unit 532 via a ball joint. Specifically, when viewed in the left-right direction, the connecting rod 531 is approximately Z-shaped. One end of the connecting rod 531 has a protrusion extending along the rotation axis of the rotating body 52 (i.e., the first axis AX1), which can be rotatably inserted into the through hole at the front end of the connecting ear 5224. The other end of the connecting rod 531 has a ball head.

[0090] In addition, such as Figures 5 to 8 As shown, the drive unit 532 includes a motor 5321, a lead screw 5322, and a slider 5323. The lead screw 5322 extends in a direction intersecting (perpendicular to) the rotation axis (i.e., the first axis AX1) of the rotating body 52, and is driven to rotate by the motor 5321. The slider 5323 is threadedly connected to the lead screw 5322 and connected to the other end of the connecting rod 531 via a ball joint. Specifically, the housing of the motor 5321 is fixed to the mounting base 54 by screws or the like, and the shaft of the motor 5321 is connected to one end of the lead screw 5322. An encoder disk 5324 is integrally formed on the lead screw 5322. The encoder disk 5324 is disc-shaped, extending radially outward from the lead screw 5322; and light-shielding parts and light-receiving parts are arranged circumferentially. The slider 5323 is supported on the mounting base 54 in a manner that allows it to slide along the lead screw 5322, and is penetrated by the lead screw 5322. The slider 5323 includes a first slider P1 and a second slider P2. The first slider P1 and the second slider P2 are joined together to form a ball joint, and at least one (both in the illustrated example) is threadedly connected to the lead screw 5322. The ball joint formed by the first slider P1 and the second slider P2, joined by screws or clips, engages with a ball head at the other end of the connecting rod 531, thus forming a ball joint. The first slider P1 and the second slider P2 are each generally rectangular parallelepipeds. The second slider P2 is further away from the motor 5321 than the first slider P1 and has a notch P21 through which the other end of the connecting rod 531 can move. Figure 6 In the middle, the first slider P1 has a protrusion P11 on the side facing the motor 5321. The protrusion P11 is used to detect whether the slider 5323 is in the initial position using the detector 5325.

[0091] In addition, such as Figure 6 and Figure 8As shown, the drive unit 532 also includes a detector 5325. The detector 5325 detects the rotation of the code disk 5324 and whether the slider 5323 is in its initial position. Specifically, the detector 5325 is, for example, an optical detector, having a first detection port OP1 and a second detection port OP2. The first detection port OP1 clamps a portion of the light-shielding part and a light-receiving part of the code disk 5324 in the circumferential direction on both sides of the lead screw 5322. The second detection port OP2 is located in a direction intersecting the length direction of the lead screw 5322 (…). Figure 6 The detector 5325 is fixed to the mounting base 54. In other words, the detector 5325 uses the first detection port OP1 and the second detection port OP2 to detect the initial position of the slider 5323 and the rotation angle of the lead screw 5322, respectively, thereby enabling more accurate detection of the slider 5323's travel distance, and thus allowing the drive mechanism 53 to more accurately control the flip angle of the rotating body 52.

[0092] (Mounting base)

[0093] like Figure 4 As shown, the mounting base 54 is fixed to the top plate 511.

[0094] Here, as Figure 4 and Figure 6 As shown, the mounting base 54 has a fixed wall 541 and a support wall 542. The fixed wall 541 is fixed to the motor 5321. The support wall 542 supports the slider 5323 and restricts the rotation of the slider 5323. Specifically, the support wall 542 has a bottom wall and a surrounding wall, wherein the bottom wall is parallel to the lead screw 5322 and is used to fix the detector 5325, and the surrounding wall is located on the end of the bottom wall away from the motor 5321 and surrounds the slider 5323. The fixed wall 541 rises from the end of the bottom wall of the support wall 542 near the motor 5321 and is fixed to the housing of the motor 5321. This ensures that the detector 5325 is fixed to the support wall 542 of the mounting base 54; the motor 5321 is fixed to the fixing wall 541 of the mounting base 54, and the output end of the motor 5321 is connected to the lead screw 5322. This makes the assembly position of the code disk 5324, which is integrally formed with the lead screw 5322, and the detector 5325 fixed and clear, and also makes the assembly position of the detector 5325 and the slider 5323, which is threaded onto the lead screw 5322, fixed and clear. This ensures that all components of the drive unit 532 (such as the alignment of the first detection port OP1 of the detector 5325 and the light-shielding and light-receiving parts of the code disk 5324, and the alignment of the second detection port OP2 and the protrusion P11 of the slider 5323 when the slider 5323 is in the initial position) are assembled with the mounting base 54 as the reference, thereby reducing the assembly position error.

[0095] According to the massage chair 1 of this embodiment, the rotating body 52 is connected to the armrest body 51 in such a way that it can rotate around the first axis AX1 and stand up or lie down relative to the upper surface 5111 of the armrest body 51. Therefore, when the rotating body 52 is, for example, a control unit, by rotating the rotating body 52 to lie down relative to the upper surface 5111 of the armrest body 51, it can be conveniently laid down when not in use, thereby avoiding the control unit or the like from becoming an obstacle to the user's vision or movement.

[0096] Furthermore, according to the massage chair 1 of this embodiment, when the rotating body 52 is reclined relative to the upper surface 5111 of the armrest body 51, the main body of the rotating body 52 does not overlap with the drive mechanism 53 when viewed from above. Therefore, the space where the armrest body 51 overlaps with the main body of the rotating body 52 when reclined from above can be fully utilized, for example, by providing a storage slot.

[0097] Furthermore, in the massage chair 1 according to this embodiment, the drive unit 532 is connected to the other end of the connecting rod 531 by a ball joint, so that jamming can be avoided when the drive unit 532 drives the connecting rod 531 to rotate.

[0098] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above embodiments.

[0099] For example, in the above embodiment, the rotating body 52 includes a control terminal 521 and a bracket 522, but is not limited to this, such as... Figure 9 As shown, the rotating body 52 can also be constituted solely by the control terminal 521, or, as... Figure 10 As shown, the rotating body 52 may also be a support such as a charging base that supports the control unit.

[0100] Furthermore, in the above embodiment, the rotating body 52 protrudes from the upper surface 5111 when lying down relative to the upper surface 5111, but it is not limited to this. Alternatively, the rotating body 52 when lying down relative to the upper surface 5111 may be flush with the upper surface 5111.

[0101] In addition, in the above embodiments, a storage groove for storing the rotating body 52 can be provided on the armrest body 51 at a position below the rotating body 52 for reclining.

[0102] It should be understood that within the scope of this utility model, the various parts in the embodiments can be freely combined, or the various parts in the embodiments can be appropriately modified or omitted.
