Description

Technical Field

[0001] The present invention relates to the technical field of massage equipment, and in particular to an intelligent massage chair. Background Art

[0002] In recent years, with the accelerating pace of life, sub-health issues have become increasingly prominent, and people's demand for massage has also been increasing. Traditional massage is difficult to develop rapidly due to limitations in venues, costs, and professional level of personnel. Smart massage chairs are increasingly recognized by the public because they can utilize fragmented time, can be used at home, and are relatively low in cost.

[0003] The existing smart massage chairs on the market are usually three-sided wrapped structures, that is, the smart massage chair includes a chair frame with a backrest and armrests installed on the left and right sides of the chair frame. The backrest of the chair frame is set behind the user to support the user's body, and the armrests are set on the left and right sides of the user to support the user's arms; the backrest and the two armrests are usually high, so that the massage chair needs to be sat in from the front when using it. However, the existing smart massage chairs are usually also equipped with a leg massage device on the front, which is used to massage the user's calves. In this way, for users with inconvenient legs and feet, there are certain obstacles when sitting in the massage chair from the front. In response to this problem, some solutions have emerged in this field in recent years.

[0004] For example, in the massage chair disclosed in the Japanese patent document with the publication number JP 2013-212349A, the leg massage device can be stored under the seat in the chair frame to avoid the leg massage device from causing obstacles when the user sits in the massage chair from the front, thereby facilitating the user to sit in the massage chair from the front. However, because the height and depth of the seat are limited by reasonable ergonomic values, and the leg massage device must be stored under the seat, the size of the leg massage device is greatly limited, and the leg massage device can only be made relatively small. However, under the premise that massage devices and functions are increasingly abundant today, leg massage devices with smaller sizes can no longer meet the needs of the public.

[0005] Another example: In the massage chair disclosed in the Chinese patent document with publication number CN107693297A, the armrest is configured to be able to be opened from the side of the chair frame. The chair frame includes a base (i.e., a seat) and a backrest. The rear side of the armrest is rotatably connected to the backrest, and the front side of the armrest is connected to the base through a snap that can be opened and closed. In this way, the armrest can be rotated 0-90° outward around the vertical axis, so that it is convenient for the user to sit on the massage chair from the side. However, since the armrest is opened outward, sufficient space must be reserved on the outside of the massage chair during the process of opening the armrest, which is not conducive to placing the massage chair in a smaller space; and after the user sits on the massage chair from the side, the user needs to turn sideways to pull the armrest inward, which is inconvenient in use. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an intelligent massage chair, which is convenient for users to sit in the massage chair and can reduce the occupied space.

[0007] To achieve the above object, the present invention provides an intelligent massage chair, comprising a chair frame and armrests installed on the left and right sides of the chair frame, at least one of the armrests is connected to the chair frame through a flip device, the flip device comprises a base installed on the chair frame, and a flip fixing seat rotatably installed on the base around a rotation axis extending left and right, and the flip fixing seat is fixed to the armrest;

[0008] When the flipping device flips the armrest to a set position, the chair frame has a side seat opening on the armrest side.

[0009] Furthermore, the intelligent massage chair also includes a connecting rod connected between the chair frame and the flip device, the chair frame includes a backrest frame and a seat frame that are rotatably connected, the base is hinged to the backrest frame and one end of the connecting rod, and the other end of the connecting rod is hinged to the seat frame.

[0013] Furthermore, the flipping device also includes a base shaft extending axially along the rotation axis, a rotating base sleeve threadedly connected to the outer periphery of the base shaft, a driving source fixed to the base, and a transmission unit. The driving source is connected to the rotating base sleeve through the transmission unit to drive the rotating base sleeve to rotate, the base shaft is fixedly connected to the base, and the rotating base sleeve is fixed to the flipping fixed seat.

[0014] Furthermore, the flipping device also includes a flipping connecting sleeve sleeved on the outer periphery of the rotating base sleeve, one end of the flipping connecting sleeve is provided with a limiting flange portion fixedly connected to the flip fixing seat, the limiting flange portion is located between the flip fixing seat and the base shaft in the axial direction of the base shaft and can abut and cooperate with the base shaft, and the other end of the flipping connecting sleeve is fixedly connected to the rotating base sleeve.

[0020] Furthermore, a limiting boss is fixed on the armrest, and a limiting groove is provided in the chair frame;

[0021] When the armrest is not turned over to block the side seat entrance, the limiting boss is located in the limiting groove.

[0022] As described above, the intelligent massage chair according to the present invention has the following beneficial effects:

[0023] In the present application, when the flip fixed seat in the flip device rotates around the rotating axis extending left and right, it drives the armrest fixedly connected to the flip fixed seat to flip up and down, and the armrest is rotated open from the side to form a side entry for the user to sit in the massage chair from the left and right sides, which is convenient for the user to sit in the massage chair; and, because the armrest is rotated open by flipping up and down, rather than flipping open outward around the vertically extending axis as in the prior art, there is no need to reserve a large space on the left and right sides of the massage chair in the process of forming the side entry by flipping the armrest, thereby reducing the space occupied by the massage chair, facilitating the placement of the massage chair in a smaller space, and ultimately greatly improving the convenience of using the massage chair.

[0066] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0067] It should be noted that the structures, proportions, sizes, etc. drawn in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0068] The present application provides a smart massage chair, referred to as a massage chair. Figure 1 and Figure 2 As shown, the massage chair includes a chair frame 10 and armrests 20 installed on the left and right sides of the chair frame 10; in particular, as shown in FIG. Figure 5 As shown, at least one armrest 20 is rotatably connected to the chair frame 10 via a flip device 30. In this way, only the left armrest 20 may be connected to the chair frame 10 via the flip device 30, or only the right armrest 20 may be connected to the chair frame 10 via the flip device 30, or both the left and right armrests 20 may be connected to the chair frame 10 via the flip device 30. In this embodiment, both the left and right armrests 20 are connected to the chair frame 10 via a flip device 30, and the connection structure between the chair frame 10 and the left armrest 20 and the connection structure between the chair frame 10 and the right armrest 20 are bilaterally symmetrical. The following takes the right armrest 20 of the massage chair as an example to describe the preferred connection structure between the armrest 20 and the chair frame 10.

[0069] like Figure 5 As shown, the flip device 30 includes a base 31 installed on the right side of the chair frame 10, and a flip fixed seat 32 that can be rotatably installed on the base 31 around a rotation axis extending left and right, and the flip fixed seat 32 is fixed to the armrest 20. Therefore, when the flip fixed seat 32 rotates around the rotation axis extending left and right, the flip fixed seat 32 drives the armrest 20 to rotate together, that is, the armrest 20 is flipped up and down. In this way, when the user needs to sit in the massage chair, the flip fixed seat 32 in the flip device 30 can be rotated, and the flip fixed seat 32 drives the armrest 20 to flip up to a set position, or flip down to a set position. Figure 2In the view shown, the armrest 20 is flipped from the normal massage position W1 to the set position W2, thereby rotating and opening the armrest 20 from the side. The armrest 20 is also in an open state, so that a side entrance 40 is formed on the right side of the chair frame 10 for the user to sit in the massage chair from this side, thereby making it convenient for the user to sit in the massage chair, especially for users with mobility impairments to sit in the massage chair; and, because the armrest 20 is rotated and opened by flipping up and down, rather than flipping outward around a vertically extending axis as in the prior art, there is no need to reserve a large space on the left and right sides of the massage chair in the process of forming the side entrance 40 by flipping the armrest 20, thereby reducing the space occupied by the massage chair, facilitating the placement of the massage chair in a smaller venue, and ultimately greatly improving the convenience of using the massage chair. After the user sits in the massage chair from the side, the flip fixing seat 32 in the flip device 30 rotates in the opposite direction and resets, driving the armrest 20 to flip in the opposite direction and reset. The armrest 20 is in a closed state, and the massage chair can be used normally afterwards. This eliminates the need for the user to manually buckle the armrest 20 after sitting in the massage chair in the prior art, thereby improving the convenience of operating the massage chair and, on the other hand, improving the convenience of using the massage chair.

[0070] Furthermore, the fixing method between the armrest 20 and the flip fixing seat 32 is preferably: Figure 5 As shown, a flip connecting plate 23 is provided on the inner side surface (i.e., the left side) of the armrest 20 facing the chair frame 10, and a fixing groove 21 is provided on the flip connecting plate 23. The contour shape of the fixing groove 21 is adapted to the contour shape of the flip fixing seat 32, and both are elliptical. The flip fixing seat 32 is tightly installed in the fixing groove 21, thereby realizing the fixed connection between the flip fixing seat 32 and the armrest 20. Preferably, matching positioning grooves and positioning columns 321 are respectively provided on the armrest 20 and the flip fixing seat 32, which can realize the positioning of the armrest 20 and the flip fixing seat 32 when they are fixedly connected, and can also improve the reliability of the fixed connection between the armrest 20 and the flip fixing seat 32. Based on this, as Figure 5 As shown, the armrest 20 is fixed with a positioning column 321 in the fixing groove 21; Fig.10 and Fig.11 As shown, a positioning groove which is tightly matched with the positioning column 321 is provided on the outer side surface (i.e., the right side surface) of the flip fixing seat 32 facing the bottom of the fixing groove 21. Fig.10 and Fig.11 As shown, a positioning column 321 is integrally provided on the outer side surface of the flip fixing seat 32 , and a positioning groove tightly matched with the positioning column 321 is formed at the bottom of the fixing groove 21 of the armrest 20 .

[0071] Furthermore, if Figure 1 and Figure 2As shown, the chair frame 10 includes a backrest frame 101 for supporting the user's back, and a seat frame 102 for supporting the user's buttocks and thighs. The backrest frame 101 and the seat frame 102 can be fixedly connected or rotatably connected via a rotating shaft. The massage chair also includes a leg massage device 60 for massaging the user's calves. The leg massage device 60 is arranged on the front side of the seat frame 102 and is rotatably connected to the seat frame 102 via a rotating shaft. Preferably, as Figure 3 and Figure 4 As shown, a limiting boss 22 is fixed to the bottom of the front side of the armrest 20, and a limiting groove 104 is provided in the seat frame 102 of the chair frame 10; when the user sits in the massage chair from the side seat opening 40 on the side of the chair frame 10, the armrest 20 is flipped upward and is in an open state, as shown in FIG. Figure 3 As shown, the limiting boss 22 is separated from the limiting groove 104; when the user sits in the massage chair for normal use, the armrest 20 is not flipped upward and is in a closed state, such as Figure 4 As shown, the armrest 20 blocks the side seat opening 40, and the limiting boss 22 is inserted into the limiting groove 104 to limit the left and right swing of the front end of the armrest 20, thereby increasing the stability of the armrest 20 when the massage chair is in normal use.

[0072] Furthermore, in the present embodiment, the backrest frame 101 and the seat frame 102 of the chair frame 10 are rotatably connected, so that the backrest frame 101 of the chair frame 10 can be in a lying state, thereby improving the comfort of use of the massage chair. The rotation of the backrest frame 101 and the flipping of the armrest 20 may be linked or not: when the two are not linked, the position angle of the armrest 20 in the massage chair will not change when the backrest frame 101 lies down, which means that the user's arm position relative to the seat frame 102 will not change. At this time, the base 31 of the flipping device 30 is fixedly connected to the chair frame 10 by several screws; when the two are linked, the angle of the armrest 20 in the massage chair will change when the backrest frame 101 lies down, which means that the user's arm position relative to the seat frame 102 will change, further improving the comfort of the massage chair. At this time, the smart massage chair also includes a connecting rod 50 connected between the backrest frame 101 and the flipping device 30 of the chair frame 10, and the angle of the armrest 20 in the massage chair is adjusted by the connecting rod 50.

[0073] Specifically, if Figures 5 to 7As shown, the base 31 and the backrest frame 101 are hinged via a first pin fixed on the backrest frame 101, the base 31 and the rear end of the connecting rod 50 are hinged via a second pin fixed on the base 31, and the front end of the connecting rod 50 and the seat frame 102 are hinged via a third pin fixed on the seat frame 102; thus, the base 31 and the backrest frame are both provided with a first axial hole 311 for rotational cooperation at the first pin, the base 31 and the rear end of the connecting rod 50 are both provided with a second axial hole 313 for rotational cooperation at the second pin, the front end of the connecting rod 50 and the seat frame 102 are both provided with a third axial hole for rotational cooperation at the third pin, and the first pin and the second pin are staggered. When the angle between the backrest frame 101 and the seat frame 102 changes, the angle of the base 31 is changed through the connecting rod 50, thereby changing the angle of the flip device 30 as a whole relative to the backrest frame 101, and thus changing the angle of the armrest 20 fixed to the flip device 30 relative to the backrest frame 101, or in other words, the angle of the armrest 20 relative to the backrest frame 101 is adapted to the angle of the backrest frame 101 relative to the seat frame 102, so as to avoid a significant change in the relative position of the armrest 20 and the backrest frame 101. For example, when the backrest frame 101 rotates backward relative to the seat frame 102, the user will fall backward; at the same time, the flip device 30 drives the armrest 20 to move backward relative to the seat frame 102, and thus drives the arm to move backward, thereby ensuring that the position of the user's arm will not change significantly, and the user is more comfortable to use.

[0074] Preferably, a sleeve is fixed in the first shaft hole 311 of the base 31, and the first pin is rotatably inserted into the sleeve to ensure lubricity when the base 31 rotates relative to the first pin. Figure 7 As shown, a pulley 103 is installed on the backrest frame 101, and a slide groove 312 is opened in the base 31. The pulley 103 is located in the slide groove 312, and the two are guided and matched. The guiding cooperation between the pulley 103 and the slide groove 312 can prevent the flipping device 30 from swinging randomly when the angle changes, thereby ensuring the stability of the overall mechanism when the angle between the backrest frame 101 and the seat frame 102 changes, and the angle of the flipping device 30 and the armrest 20 changes accordingly.

[0075] Furthermore, the central axis of the first axial hole 311 on the base 31 may be parallel to or not parallel to the rotation axis of the flip fixing seat 32. In this embodiment, the central axis of the first axial hole 311 on the base 31 is not parallel to the rotation axis of the flip fixing seat 32, that is, an angle is formed between the central axis of the first axial hole 311 on the base 31 and the rotation axis of the flip fixing seat 32; in this way, when the angle between the backrest frame 101 and the seat frame 102 changes, when the flip device 30 drives the armrest 20 to change position in the front-to-back direction, the flip device 30 will also drive the armrest 20 to flip at a certain angle with the front side of the chair frame 10, providing greater freedom of space for the massage chair.

[0076] Further, in the flip device 30, the flip fixing seat 32 can only rotate around its rotation axis, in which case the flip fixing seat 32 can only drive the armrest 20 to flip up and down; or, the flip fixing seat 32 can move around its rotation axis while rotating, in which case the flip fixing seat 32 drives the armrest 20 to flip up and down while also driving the armrest 20 to move left and right; for example: when the flip fixing seat 32 drives the armrest 20 to flip up and open, it also drives the armrest 20 to move to the outside away from the chair frame 10, and when the flip fixing seat 32 drives the armrest 20 to flip down and close, it also drives the armrest 20 to move to the inside close to the chair frame 10. In this embodiment, the flip fixing seat 32 can be rotatably and movably installed on the base 31 around its rotation axis. Based on this, the preferred embodiment of the flip device 30 is described as follows.

[0077] like Figure 8 and Fig. 9 As shown, the flipping device 30 includes three parts: a base 31, a flipping structure and a driving structure. The base 31 is used to connect with the backrest frame 101 of the chair frame 10, so that the flipping device 30 is installed on the backrest frame 101 of the chair frame 10 as a whole; the flipping structure and the driving structure are both installed on the base 31. The flipping fixed seat 32 is a component in the flipping structure. Fig.10 and Fig.11 is a schematic diagram of the structure of the flipping structure and the driving structure in the flipping device 30, Fig.12 for Fig.10 A cross-sectional view along the rotation axis of the flip mount 32, Fig.13 for Fig.10 A cross-sectional view along the rotation axis of the flip mount 32. And, Fig.10 and Fig.12 In the embodiment, the flip fixing seat 32 is in the initial position, and the armrest 20 is in the unflipped and closed state; Fig.11 and Fig.13 In the embodiment, the flip fixing seat 32 is in the flipped position, and the armrest 20 is in the flipped-up and opened state.

[0078] like Figures 8 to 13 As shown, the flip structure of the flip device 30 includes a flip fixing seat 32, a base shaft 33, a rotating base sleeve 34, a flip connecting sleeve 36, and a turbine sleeve 38. The base shaft 33 extends axially along the rotation axis of the flip fixing seat 32, and the rotation axis of the flip fixing seat 32 is also the central axis of the base shaft 33. The left end of the base 31 is fixedly connected to the base 31 by a plurality of screws, so the left end of the base 31 is provided with a fixing hole, such as Fig. 9As shown. The rotating base sleeve 34 is threadedly connected to the outer periphery of the base shaft 33, so the outer periphery of the base shaft 33 is tapped with threads, and the inner periphery of the rotating base sleeve 34 is also tapped with threads; the flip connection sleeve 36 is sleeved on the outer periphery of the right section of the base shaft 33, and the turbine sleeve 38 is sleeved on the outer periphery of the left section of the base shaft 33. The outer periphery of the rotating base sleeve 34 is provided with an intermediate connection flange 342, and the left end of the flip connection sleeve 36 is provided with an outer connection flange 362 located outside the intermediate connection flange 342, and the right end of the turbine sleeve 38 is provided with an inner connection flange 382 located inside the intermediate connection flange 342. The outer connection flange 362, the intermediate connection flange 342 and the inner connection flange 382 are fixedly connected by a number of screws, thereby fixing the rotating base sleeve 34, the flip connection sleeve 36 and the turbine sleeve 38 together. The right end of the flip connection sleeve 36 is integrally provided with a limiting flange portion 361, which is located between the flip fixing seat 32 and the base shaft 33 in the axial direction of the base shaft 33, and the limiting flange portion 361 and the flip fixing seat 32 are fixedly connected by a plurality of screws, thereby fixing the flip connection sleeve 36 and the flip fixing seat 32. The driving structure is used to drive the turbine sleeve 38 to rotate.

[0079] When a user with mobility impairment needs to sit in the massage chair from the side, the driving structure in the flip device 30 is activated to drive the turbine sleeve 38 to rotate, and the turbine sleeve 38 drives the rotating base sleeve 34, the flip connecting sleeve 36 and the flip fixing seat 32 to rotate together. The rotating base sleeve 34 rotates relative to the base 31 and also moves axially relative to the base shaft 33, thereby driving the flip connecting sleeve 36 and the flip fixing seat 32 to move left and right together. Therefore, the flip fixing seat 32 moves in the left and right directions while rotating, driving the right armrest 20 to move to the right when it is flipped up to open, and to move to the left when it is flipped down to close. After the armrest 20 moves to the left to reset, the limiting flange 361 at the right end of the flip connecting sleeve 36 abuts against the right end of the base shaft 33, playing a limiting role during reset. Preferably, as Fig.13 As shown, an oil groove 341 is provided on the inner circumferential surface of the rotating base sleeve 34 , and grease is stored in the oil groove 341 to ensure smooth movement of the rotating base sleeve 34 .

[0080] Furthermore, if Fig.10 and Fig.11As shown, the driving structure of the flip device 30 includes a driving source 35 fixed to the base 31, a worm shaft 39 driven to rotate by the driving source 35, a transmission worm 37 rotatably supported in the base 31 by bearings 70 at both ends, and a transmission turbine 310 fixed to the transmission worm 37 by elastic pins, the worm shaft 39 and the transmission turbine 310 are transmission-matched; a turbine sleeve 38 is provided with a turbine part 381, which spirally extends and is transmission-matched with the transmission worm 37. In this way, when the driving source 35 drives the worm shaft 39 to rotate, the transmission worm 37 is driven to rotate by the engagement between the worm shaft 39 and the transmission turbine 310, thereby driving the turbine sleeve 38 to rotate, and the turbine sleeve 38 drives the rotating base sleeve 34 to rotate together. Therefore, the worm shaft 39, the transmission turbine 310, the transmission worm 37 and the turbine sleeve 38 constitute a transmission unit connected between the driving source 35 and the rotating base sleeve 34, and the driving source 35 is connected to the rotating base sleeve 34 through the transmission unit to drive the rotating base sleeve 34 to rotate. Preferably, the driving source 35 is a motor, and the worm shaft 39 can be fixedly connected to the motor shaft of the motor through a coupling, or the worm shaft 39 can be an extension of the motor shaft of the motor.

[0081] Furthermore, the intelligent massage chair also includes a controller and a current detector. The current detector is used to detect the current of the driving source 35. The current detector and the driving source 35 are both connected to the controller. The rotation of the motor can be controlled by the controller. Therefore, when the user sits in the massage chair, the controller can be used to drive the motor to rotate, so that the armrest 20 flips upward and opens the side seat opening 40, which is convenient for the user to enter the massage chair from the side seat opening 40; after that, the user uses the controller to drive the motor to rotate in the opposite direction, so that the armrest 20 flips downward to its original position and closes the side seat opening 40, thereby improving the intelligence of the massage chair. In particular, the present application detects the current of the motor through the current detector. When the current of the motor exceeds the normal value, the controller controls the motor to stop suddenly or move in the opposite direction to avoid human or mechanical interference in the movement path of the armrest 20, thereby causing people to be pinched or the mechanical structure to be damaged. The current detector can be a sensor.

[0082] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
