Description

Technical Field

[0001] The present invention relates to the field of seats, and in particular to a flexibly adjustable massage support device and seat. Background Art

[0002] As people's living standards continue to improve, their pursuit of life has gradually shifted from material pursuits to spiritual pursuits. Massage chairs are a popular piece of home and office furniture. When people sit in a fixed position for extended periods, they become fatigued, sore, and weak. Massage chairs can provide a relaxing massage.

[0003] Massage chairs currently on the market typically have a massage mechanism with a massage head installed inside the backrest. By controlling the massage mechanism, the user can relax their back by leaning back on the chair. However, a problem with existing massage chairs is that the massage head of the massage mechanism protrudes from the backrest, and the user can always feel the massage head as long as they lie on the backrest. While this can achieve the effect of massaging the back, lying on the backrest for a long time will cause back pain and discomfort, which violates the design concept of providing user comfort. In addition, the massage head is very conspicuous when exposed outside the chair back, making the chair back unsightly. In summary, when massage is not needed, the massage head of existing massage chairs is still on the backrest, making the chair very uncomfortable to sit on and cannot be used as an ordinary chair. The structure is also very unsightly.

[0004] Chinese utility model patent CN201620940770.9 discloses a "lifting massage mechanism" comprising a massage mechanism, a drive mechanism, and a vertical lift mechanism. One end of the vertical lift mechanism is linked to the drive mechanism, and the other end is linked to the massage mechanism. The vertical lift mechanism drives the massage mechanism to raise or lower in a direction perpendicular to the plane in which the massage mechanism resides. When the massage mechanism is raised to a high position, it enters a massage mode; when it is lowered to a low position, it enters a hidden storage mode. This lifting massage mechanism controls the extension and retraction of the vertical lift mechanism to enable the use or concealment of the massage mechanism. However, when this massage mechanism is specifically applied to a seat back, the seat back requires sufficient front-to-back space to accommodate the extension and retraction of the vertical lift mechanism. Since the seat back itself requires the massage mechanism, and further space is reserved for its front-to-back extension and retraction, the resulting seat back is undoubtedly thicker. However, existing seat designs pursue a thin and lightweight design, which undoubtedly conflicts with this thin and lightweight design.

[0005] The Chinese invention patent CN202110177811.9 discloses a "massage chair with kneading and percussion massage functions", which includes a backrest assembly and a seat assembly. The backrest assembly includes a backrest frame, a guide rail frame and a backrest frame. The guide rail frame is equipped with a massage movement. The guide rail frame and the backrest frame are fixed to the backrest frame through fixing parts. The massage movement moves with the guide rail assembly and can massage the human body that is attached to the outside of the massage surface. A standby cavity is provided at the lower part of the backrest frame and the guide rail frame; when the user turns off the massage operation, the massage movement returns to the standby cavity; the seat assembly, the backrest assembly can be adjusted and moved relative to the seat assembly, so that the angle between the backrest assembly and the seat assembly can be adjusted between 80°-150°. This invention provides a standby cavity beneath the backrest frame and the guide rail frame. When the massage function is not in use, the massage mechanism returns to the standby cavity, thereby eliminating the massage mechanism's function. While the massage chair can be switched between massage and normal use, the need for a separate standby cavity to accommodate the massage mechanism undoubtedly requires consideration of the entire backrest assembly design, adding to the design complexity. Furthermore, when the massage function is turned off, the massage mechanism is hidden in the standby cavity, making the massage component's function very limited, serving only as a massage seat.

[0006] In order to solve the above problems, the existing massage components designed on the chair back and having hidden functions have the disadvantages of occupying a large space and having a single function. Summary of the Invention

[0007] The present invention overcomes the deficiencies in the above-mentioned prior art and provides a flexibly adjustable massage support device; by controlling the rotation of the massage manipulator, the massage manipulator can be hidden in the frame base to realize the hidden design of the massage manipulator; it can also be extended outside the frame base to realize the massage function; and through the linkage between the support panel and the massage manipulator, in the hidden state, the support panel can be located in front of the massage manipulator to support the user, so that the massage support device can still provide support; and in the use state, the support panel can move accordingly to avoid the massage manipulator from extending; thereby, the massage support device can be flexibly switched between the two use states, and the structural design is very clever.

[0008] Then, a seat is provided, in which the massage support device is arranged on a backrest frame of the seat; and the massage support device can be used as a headrest or waist support component for supporting the user; then, in a hidden state, the support panel can support the user's waist or headrest; and in a use state, the massage manipulator is extended to massage the user's head or waist; so that the massage support device can not only have a massage effect, but also serve as a support component for supporting the user when it is not needed for massage; and has richer usage functions.

[0009] The technical solution of the present invention is achieved as follows:

[0010] A flexibly adjustable massage support device, comprising:

[0011] The massage assembly is arranged on the frame base; the massage assembly includes a longitudinally arranged massage manipulator, the upper end of which has a massage head; and the massage manipulator is configured to be able to rotate forward and backward relative to the frame base;

[0012] a support panel movably disposed at a front end of the frame base; the support panel is longitudinally disposed and configured to form a support surface at the front end of the frame base; the massage assembly is surrounded by the frame base and the support panel; and the support panel is capable of moving in a vertical direction relative to the frame base in response to a rotational movement of the massage manipulator;

[0013] The massage manipulator has a hidden state and a use state; in the hidden state, the massage manipulator is longitudinally retracted between the frame base and the support panel, the massage manipulator tends to be in a vertical upright posture, and the support panel is located directly in front of the massage manipulator to form a shielding surface; in the use state, the massage manipulator rotates to an inclined state relative to the frame base, the support panel moves synchronously to avoid the rotation of the massage manipulator, and the massage head extends forward outside the frame base.

[0014] Preferably, the device further includes a control assembly disposed below the massage assembly; the control assembly includes a main drive shaft disposed in a left-right direction below the massage assembly. Rotation of the main drive shaft drives the massage assembly relative to the frame base and simultaneously drives the support panel to move. Simply controlling the rotation of the main drive shaft simultaneously drives the massage assembly and the support panel, resulting in a clever structural design that creates a sense of technology when the configuration changes. Furthermore, the main drive shaft is disposed below the massage assembly, creating a rational layout that reduces the space occupied by the front and rear of the frame base, allowing for a thinner and lighter frame base.

[0015] Preferably, the control assembly further comprises a flip motor provided on the frame base, the flip motor being configured to drive the main drive shaft to rotate. The use of a motor drive makes the control more convenient and accurate.

[0016] Preferably, the massage assembly is rotationally coupled to the frame base; a gear mechanism is provided between the main drive shaft and the massage assembly to maintain linkage between the two. The gear mechanism includes a driving toothed member disposed on the main drive shaft and a corresponding driven toothed member disposed at the lower end of the massage assembly; the driving toothed member and the driven toothed member engage with each other. The principle of gear transmission is employed to achieve effective transmission, enabling the massage assembly to be instantly driven by rotation of the main drive shaft. Furthermore, the gearing between the driving toothed member and the driven toothed member allows the massage assembly to remain in any rotational adjustment position after rotational adjustment.

[0017] Preferably, the outer contour of the driven gear is fan-shaped. The present invention controls the massage manipulator by controlling its forward and backward rotation to hide or use the massage manipulator. Compared with the prior art structure for controlling the extension and retraction of the massage head, this undoubtedly occupies less space on the frame base. The massage assembly only needs to rotate within a certain angle range to switch between the two states, so the driven gear only needs to be designed as a fan-shaped structure, which is more reasonable and allows the thickness of the frame base to be designed to be thinner.

[0018] Preferably, the massage assembly further includes a drive assembly and a rotating horizontal axis for controlling the operation of the massage manipulators; the massage manipulators are provided in pairs; the massage manipulators are mirror-imaged and disposed on the left and right sides of the drive assembly; the massage assembly is rotatably connected to the frame base via the rotating horizontal axis so that the entire massage assembly can be flipped forward and backward relative to the frame base. The entire massage assembly can rotate relative to the frame base, thereby allowing the massage manipulators to rotate, extend, or retract relative to the frame base.

[0019] Preferably, the horizontal rotating shaft is a long axis and extends horizontally through the massage assembly; the frame base includes support platforms on the left and right sides, with the massage assembly disposed between the two support platforms; and both ends of the horizontal rotating shaft extend through the massage assembly and are rotatably connected to the support platforms. This provides a more stable rotation structure.

[0020] Preferably, during the rotation and extension of the massage manipulator, the support panel simultaneously moves downward and backward along the frame base; a gear-link assembly is provided between the support panel and the main drive shaft to keep the two linked; the gear-link assembly includes an active auxiliary gear member provided on the main drive shaft, a driven auxiliary gear member rotatably provided on the frame base and engaged with the active auxiliary gear member, and a drive connecting rod with both ends hinged to the driven auxiliary gear member and the support panel; the active auxiliary gear member rotates with the main drive shaft to drive the driven auxiliary gear member to rotate; the rotation of the driven auxiliary gear member can drive the drive connecting rod to move up and down to control the up and down movement of the support panel. The rotation of the gear is then converted into the up and down movement of the drive connecting rod, thereby controlling the up and down movement of the support panel, which is an ingenious design.

[0021] Preferably, the driven gear is positioned above the active gear and has a fan-shaped structure. A connecting seat is provided on the driven gear, to which the lower end of the drive link is hinged. When the support panel moves from a concealed state to an operational state, the driven gear rotates to cause the connecting seat to move rearward and downward. The gear-link assembly is arranged vertically, offering a rational layout that minimizes front-to-back space occupation. The rotation of the driven gear drives the drive link up and down, resulting in an ingenious transmission design.

[0022] Preferably, the support panel is provided with connecting side panels on the left and right sides, respectively, and the frame base includes support platforms on the left and right sides; a sliding guide mechanism is provided between each connecting side panel and the support platform on the corresponding side; the sliding guide mechanism includes a first guide pin and a second guide pin spaced apart from each other on the connecting side panels, and a first longitudinal guide groove and a second longitudinal guide groove respectively provided on the support platform; the first guide pin is slidably provided in the first guide groove, and the second guide pin is slidably provided in the second guide groove; in a hidden state, the first guide pin is located at the upper end of the first guide groove, and the second guide pin is located at the upper end of the second guide groove; in an in-use state, the first guide pin and the second guide pin move downward to the bottom ends of the first guide groove and the second guide groove, respectively, to achieve double-track sliding, so that the support panel can move smoothly relative to the frame base.

[0023] Preferably, the first guide pin is arranged at the upper end of the connecting side plate, and the second guide pin is arranged at the middle position of the connecting side plate; and the position of the first guide pin is further back than the position of the second guide pin; accordingly, the first guide groove is located above and behind the second guide groove.

[0024] Preferably, from front to back, the first guide groove and the second guide groove are both inclined toward the rear and downward, and the inclination of the second guide groove is greater than that of the first guide groove. Furthermore, in the use state, when moving from front to back, the support panel is tilted toward the rear and downward. The first and second guide grooves are tilted so that when the support panel moves downward, it moves downward to a more rearward position. Furthermore, because the inclination of the second guide groove is greater than that of the first guide groove, when the massage mode is in progress, the support panel is tilted toward the rear and downward from front to back. When the human body is being massaged, the back of the human body is also tilted toward the rear. This better conforms to the inclination of the user's back during massage and is more ergonomically sound. The design is more thoughtful.

[0025] Preferably, the support panel is a sheet metal component, which enables the support panel to be designed to be thinner and lighter, further reducing the overall volume of the device while ensuring structural strength.

[0026] Preferably, the frame base includes support platforms on the left and right sides, the massage assembly is arranged between the two support platforms, and the support panel is connected to the front ends of the two support platforms, so that the massage manipulator can be enclosed in the cavity formed by the support platform and the support panel, thereby achieving a better concealment effect.

[0027] Preferably, the driving assembly includes a kneading motor, a housing, and a gear transmission control assembly disposed in the housing; the gear transmission control assembly is configured to transmit power input from the kneading motor to the massage manipulator to drive the massage manipulator to move.

[0028] A seat comprises a backrest frame and a flexibly adjustable massage support device; the frame base is mounted on the backrest frame, so that the massage support device can be used as a headrest or lumbar support for the seat; it can serve as a support component for the user and also provide a massage function.

[0029] The design starting point, concept and beneficial effects of the present invention using the above technical solution are:

[0030] First, the present invention provides a flexible massage support device. By controlling the rotation of the massage manipulator, the massage manipulator can be hidden in the frame base, realizing a hidden design of the massage manipulator; or it can be extended outside the frame base to realize a massage function. Furthermore, through the linkage between the support panel and the massage manipulator, the support panel can be located in front of the massage manipulator to support the user in the hidden state, so that the massage support device can also provide support. In the use state, the support panel can move accordingly to avoid the massage manipulator from extending. Thus, the massage support device can be flexibly switched between the two use states, and the structural design is very clever. The massage support device can then be set on the backrest frame of the seat, and the massage support device can be used as a headrest or waist support component for supporting the user. In the hidden state, the support panel can support the user's waist or headrest. In the use state, the massage manipulator extends to massage the user's head or waist. The massage support device can not only achieve a massage effect, but also serve as a support component for supporting the user when massage is not needed. It has more functions.

[0031] Secondly, the rotation of the main drive shaft can drive the massage component and the support panel to drive synchronously; a gear connection mechanism is provided between the main drive shaft and the massage component to link the two; a gear connecting rod assembly is also provided between the main drive shaft and the support panel to link the two; the flip motor is used to drive the main drive shaft to rotate, and then the movement of the massage component and the support panel can be controlled simultaneously by only one motor, and the control structure is ingenious; and the massage component and the support panel deform and move at the same time, so that the deformation effect of the massage support device is better and more technological.

[0032] Furthermore, the main drive shaft is positioned below the massage assembly; simply controlling the main drive shaft's rotation drives the massage assembly's rotation and the support panel's vertical movement. This rational layout reduces the space occupied by the frame's front and rear surfaces. Furthermore, the massage manipulator controls the concealment and extension of the massage head by flipping the massage assembly back and forth relative to the frame. Compared to existing mechanisms for controlling the extension and retraction of the massage head, this undoubtedly occupies less space within the frame. The massage assembly only needs to rotate within a certain angle range to switch between the two states, resulting in a more rational design and the frame's thickness can be designed to be thinner.

[0033] In addition, in the hidden state, the support panel adopts double tracks to slide with the support platform, so that the sliding and supporting structure of the support panel are more stable; and the support panel can move backward at the same time when sliding downward; it can still support the lower part of the user's massage area; and after the support panel slides to the bottom, from front to back, the support panel will be in a state of tilting backward and downward, and when the human body is being massaged, the back of the human body is also in a state of tilting backward, which is more in line with the inclination of the user's back in the massage state, more in line with ergonomics, and more thoughtful design.

DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0050] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise clearly defined. The terms "first", "second", "third", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0051] The various directional words involved in this embodiment, such as front, back, etc., are described based on the user's actual usage state when sitting on the seat.

[0052] The specific implementation of the present invention is as follows:

[0053] like Figure 1-10As shown, the present invention first provides a flexible and adjustable massage support device, comprising a frame base 1, a massage component 2, and a support panel 3; wherein the massage component 2 includes two longitudinally arranged massage manipulators 4 and a drive component 5 disposed between the two massage manipulators 4; a massage head 4a is provided at the upper end of each massage manipulator 4, and the drive component 5 is used to drive the massage manipulators 4 to perform massage actions such as knocking or hammering; and the massage component 2 is rotatably connected to the frame base 1 via a rotating horizontal axis 6, so that the massage component 2 as a whole can be flipped relative to the frame base 1, thereby allowing the massage manipulators 4 to rotate back and forth relative to the frame base 1. The frame base 1 includes support platforms 7 located on the left and right sides, respectively, and the massage component 2 is disposed between the two support platforms 7; the support panel 3 is movably disposed at the front ends of the two support platforms 7, the support panel 3 is disposed longitudinally, and the support panel 3 is configured to form a support surface at the front end of the frame base 1, and the massage component 2 is surrounded by the frame base 1 and the support panel 3; the support panel 3 can move vertically relative to the frame base 1 in response to the rotation of the massage manipulators 4. A control component 8 for controlling the flipping of the massage component 2 and the movement of the support panel 3 is also provided on the frame base 1; the massage manipulator 4 has a hidden state and a use state. In the hidden state, the massage manipulator 4 tends to be in a vertical upright position, and the support panel 3 is located directly in front of the massage manipulator 4 to form a shield; in the use state, the control component 8 will drive the massage component 2 to flip so that the massage manipulator 4 rotates forward relative to the frame base 1, and the massage head 4a will extend forward outside the frame base 1; and the support panel 3 simultaneously moves downward and backward along the frame base 1 to avoid the extension movement of the massage manipulator 4.

[0054] The massage support device of the present invention is primarily used in seating, and can be used as a lumbar support or headrest. This allows for convenient control of its massage function. Specifically, in a concealed state, the massage manipulator 4 is retracted between the frame base 1 and the support panel 3. The support panel 3 then serves as a lumbar support or headrest, providing support for the user. The user cannot sense the presence of the massage manipulator 4, making it indistinguishable from the support components of conventional seating. This aesthetically pleasing structure allows the massage manipulator 4 to be concealed. When the massage function is desired, the massage manipulator 4 is controlled to rotate to a use state. The massage head 4a extends outside the frame base 1, allowing the massage manipulator 4 to tap or pound the user, providing a massage effect. The support panel 3 can also move downward and backward to avoid the extension of the massage manipulator 4, preventing interference between the two. The support panel 3 can still provide support for the user. The massage support device of the present invention, through the linkage between the massage manipulator 4 and the support panel 3, can flexibly switch between a normal support state and a massage use state. This ingenious design offers exceptional flexibility.

[0055] like Figure 4 、 9 As shown in Figures 10 and 10, the rotating horizontal axis 6 is a long axis. The rotating horizontal axis 6 is completely arranged in the two massage manipulators 4 and the drive assembly 5 in the left and right directions. The two ends of the rotating horizontal axis 6 respectively pass through the massage assembly 2 and are rotatably connected to the support platform 7; thereby, the massage assembly 2 as a whole can be stably flipped back and forth relative to the frame base 1, and the rotation structure is more stable. The drive assembly 5 includes a kneading motor 9, a housing 5a, and a gear transmission control assembly 9A arranged in the housing 5a. The kneading motor 9 works and drives the gear transmission control assembly 9A to move, so as to realize the control of the two massage manipulators 4 to perform massage work; the drive assembly 5 adopts the massage movement commonly found in existing seat massage devices, so it will not be described here.

[0056] like Figure 3-9 As shown, the control assembly 8 is used to control the rotation of the massage assembly 2 relative to the frame base 1. Specifically, the control assembly 8 includes a tilting motor 10 disposed on the outside of one of the support platforms 7 and a main drive shaft 11 disposed in the left-right direction below the massage assembly 2. The tilting motor 10 controls the rotation of the main drive shaft 11. A gear mechanism is provided between the main drive shaft 11 and the lower end of the massage assembly 2. The gear mechanism includes a driving gear 12 disposed on the main drive shaft 11 and a corresponding driven gear 13 disposed at the lower end of the massage assembly. Specifically, the driving gear 12 is capable of rotating synchronously with the main drive shaft 11, and two driving gears 12 are spaced apart on the main drive shaft 11. The driven gears 13 are disposed on either side of the bottom of the drive assembly housing 5a. The driving gears 12 and the driven gears 13 engage with each other. Therefore, when the main drive shaft 11 rotates, the driving gear 12 rotates synchronously and drives the driven gear 13 to rotate, causing the massage assembly 2 to tilt relative to the frame base 1. Under the control of the flip motor 10, the massage component 2 can be flipped and stay in any adjusted position without the need for an additional locking structure; the active gear 12 and the driven gear 13 can achieve a locking effect. Furthermore, the outer contour of the driven gear 13 is fan-shaped; the present invention controls the massage manipulator 4 to be hidden or used by controlling the forward and backward rotation of the massage manipulator 4; compared with the structure for controlling the extension and retraction of the massage head in the prior art, it undoubtedly occupies less space on the frame base 1; the massage component 2 only needs to rotate within a certain angle range to switch between the two states, so the driven gear 13 only needs to be designed as a fan-shaped structure, which is more reasonable; the main drive shaft 11 is set below the massage component 2, and the massage component 2 can be controlled to rotate by controlling the rotation of the main drive shaft 11, which reduces the occupation of the front and rear space and enables the frame base 1 to be designed to be lighter and thinner.

[0057] like Figure 1-8As shown, the left and right sides of the support panel 3 are respectively provided with connecting side panels 14 extending backward; and a sliding guide mechanism is provided between the connecting side panels 14 on either side and the support platform 7 on the corresponding side, and the sliding guide mechanism enables the support panel 3 to be stably moved up and down along the frame base 1. Specifically: the sliding guide mechanism includes a first guide pin 15 and a second guide pin 16 provided on the connecting side panel 14, and a first guide groove 17 and a second guide groove 18 provided longitudinally on the support platform 7. The first guide pin 15 is provided at the upper end of the connecting side panel 14, and the second guide pin 16 is provided at the middle position of the connecting side panel 14; and the position of the first guide pin 15 is further back relative to the position of the second guide pin 16. Correspondingly, the first guide groove 17 is located above and behind the second guide groove 18; the first guide pin 15 is slidably provided in the first guide groove 17, and the second guide pin 16 is slidably provided in the second guide groove 18. Thus, double-track sliding is achieved, so that the support panel 3 can move smoothly relative to the frame base 1. As shown Figure 1 As shown, when the massage manipulator 4 is in the hidden state, the first guide pin 15 is located at the upper end of the first guide groove 17, and the second guide pin 16 is located at the upper end of the second guide groove 17. Figure 2 As shown, when the massage manipulator 5 rotates forward to the use state, the first guide pin 15 and the second guide pin 16 will move downward to the bottom ends of the first guide slot 17 and the second guide slot 18; and from front to back, the first guide slot 17 and the second guide slot 18 are both tilted toward the rear and downward, so that the support panel 3 will move downward to a more rearward position; furthermore, the slope of the second guide slot 18 is greater than the slope of the first guide slot 17, so that in this state, from front to back, the support panel 3 will be in a state of tilting toward the rear and downward, and when the human body is being massaged, the back of the human body is also in a state of tilting toward the rear, which is more in line with the inclination of the user's back during massage and more ergonomic; the design is more thoughtful; and the lower end of the support panel 3 is further retracted relative to the frame base 1, making the structure more beautiful and reducing the space occupied by the front and rear of the frame base 1. In addition, the support panel 3 is a sheet metal part. If a sheet metal part is used, the support panel 3 can be designed to be lighter and thinner, further saving the overall volume of the device; while ensuring structural strength.

[0058] Further speaking: Figure 3-8As shown, a gear connecting rod assembly is further provided between the support panel 3 and the main drive shaft 11 so that the support panel 3 can move synchronously with the rotation of the main drive shaft 11. The gear connecting rod assembly is provided between the connecting side plate 14 and the main drive shaft 11. The gear connecting rod assembly includes an active auxiliary tooth member 19 provided on the main drive shaft, a driven auxiliary tooth member 20 rotatably provided on the support platform 7 and gear-engaged with the active auxiliary tooth member 19, and a driving connecting rod 21 whose two ends are respectively hinged to the driven auxiliary tooth member 20 and the connecting side plate 14; specifically Said active auxiliary gear member 19 rotates synchronously with the main drive shaft 11, and said driven auxiliary gear member 20 is a fan-shaped structure. The rotation of the active auxiliary gear member 19 can drive the driven auxiliary gear member 20 to rotate relative to the support platform 7; a connecting seat 20a is provided on the driven auxiliary gear member 20, and the lower end of the driving connecting rod 21 is hinged on the connecting seat 20a, and the upper end of the driving connecting rod 21 is hinged on the connecting side plate 14, and the hinge position of the driving connecting rod 21 and the connecting side plate 14 is located between the first guide pin 15 and the second guide pin 16; then as Figure 7-8 As shown, in the hidden state, the connecting seat 20a is located at the upper end of the driven auxiliary gear member 20. When the main drive shaft 11 rotates to control the massage assembly 2 to flip forward, the active auxiliary gear member 19 rotates synchronously, driving the driven auxiliary gear member 20 to rotate. The connecting seat 20a also moves downward, thereby driving the driving connecting rod 21 downward. The driving connecting rod 21 pulls the support panel 3 downward along the support platform 7. This allows the main drive shaft 11 to simultaneously drive the massage assembly 2 to flip and the support panel 3 to move along the support platform 7. To reset, simply control the main drive shaft 11 to rotate in the opposite direction, making adjustment very convenient and simple.

[0059] like Figure 11-13 As shown, the present invention then provides a seat, which includes a backrest frame 22, which includes side supports 22a located on the left and right sides respectively, and the frame base 1 is connected between the two side supports 22a; so that the massage support device can be used as a lumbar support component or headrest component of the seat back; in the massage state, the massage manipulator 4 extends and can massage the user's waist or head for relaxation; in the hidden state, the support panel 3 is located in the front, and the support panel 3 can play the role of a lumbar support or headrest to provide support. This allows the massage support device to provide a massage function while also serving as a support component; it has richer functions and is more flexible to use.

[0060] Furthermore, the frame base 1 is capable of sliding up and down relative to the side support 22a. Specifically, a travel motor 23 and a power shaft 24 controlled by the travel motor 23 are provided at the upper end of the frame base 1. The two ends of the power shaft 24 are located outside the frame base 1, and travel gears 25 are provided at each end of the power shaft 24. Toothed belts 26 are provided along the length of the side support 22a, each capable of engaging with the travel gears 25. Guide grooves 27 are also provided along the inner side of the side support 22a along its length. Both ends of the main drive shaft 11 and the power shaft 24 are slidably restrained within the guide grooves 27. Consequently, under the control of the travel motor 23, the frame base 1 is capable of adjusting its vertical movement along the chair back frame 22, thereby further adjusting the height of the massage support device on the chair back frame 22.

[0061] Then the massage support device of the present invention can be used as a waist support or headrest for a seat; Figure 11 As shown, in the hidden position, the support panel 3 is used to support the user, and the massage manipulator 4 is hidden in the frame base 1; and a support cushion (not shown) is also provided on the support panel 3 to make the support more comfortable. Figure 12 As shown, in the use state, the massage manipulator 4 is controlled to rotate so that the massage head 4a protrudes forward; the support panel 3 moves downward and backward accordingly to avoid the extension of the massage manipulator 4; thereby, the massage manipulator 4 can massage the user; and the support panel 3 can still support the user's waist and back at this time; the structural design is very clever, the support panel 3 and the massage manipulator 4 move synchronously, and can flexibly switch between the two states; and the structure is simple and beautiful.

[0062] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
