Description

Technical Field

[0001] This utility model relates to seats, specifically a rocker seat mechanism assembly and a fitness exercise seat. Background Technology

[0002] Existing office chairs generally have limited functions. Some are only for sitting, while others can be used for exercise. However, the functions and fitness effects of these existing office chairs that can be used for exercise are not ideal, as they target only one part of the body and are inefficient. Utility Model Content

[0003] One of the technical problems to be solved by this utility model is to provide a seesaw seat mechanism assembly.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A seesaw seat mechanism assembly, characterized in that it includes: a seesaw seat frame, a seesaw seat cushion frame, a seesaw seat front lifting mechanism, and a seesaw seat rear lifting mechanism;

[0006] Both the front lifting mechanism and the rear lifting mechanism of the rocker seat are installed on the seat bracket fixed inside the outer frame of the seat;

[0007] The rear support point of the rocker seat frame is connected to the outer frame of the seat to form a rotating fit with the horizontally arranged pivot. The front lifting mechanism of the rocker seat can drive the front support point of the rocker seat frame to move up and down.

[0008] The rocker seat cushion bracket is used to install the seat cushion. The front support point of the rocker seat cushion bracket is connected to the rocker seat frame and simultaneously forms a rotational fit with the horizontally arranged pivot and a sliding fit along the straight line. The rocker seat rear lifting mechanism can drive the rear support point of the rocker seat cushion bracket to move up and down. The aforementioned straight line direction is generally preferred to be the front and back direction of the seat, but other straight lines can also be used.

[0009] The working principle and usage of the seesaw seat mechanism assembly in this utility model are as follows:

[0010] When a user sits on the seat cushion and holds onto the armrests, the front and rear lifting mechanisms of the rocker seat are repeatedly controlled to drive the lifting motion. This causes the rocker seat frame to oscillate within an acute angle range around its rear fulcrum, while the rocker seat cushion frame oscillates within an acute angle range around its front fulcrum and simultaneously performs a linear translational motion. The aforementioned acute angle range is generally 0° to 25°. As a result, the user is subjected to the combined motion of the rocker seat frame and the rocker seat cushion frame. The user needs to exert force to resist this combined motion to remain seated, thus achieving high-efficiency exercise while seated. Experiments have shown that the fingers, palms, arms, abdominal muscles, and internal organs can all be effectively exercised.

[0011] Preferably, the bottom front end of the seesaw frame is provided with two front support points distributed on the left and right sides;

[0012] The rocker seat front lifting mechanism includes: a rocker seat front lifting left bearing, a rocker seat front lifting right bearing, and a rocker seat front lifting sliding support, all fixed to the seat bracket; the two ends of the rocker seat front lifting output shaft are rotatably connected to the rocker seat front lifting left bearing and the rocker seat front lifting right bearing, respectively; and the rocker seat front lifting output shaft is fixedly fitted with a rocker seat front lifting left sprocket and a rocker seat front lifting right sprocket; the rocker seat front lifting left slide rail and the rocker seat front lifting right slide rail are slidably connected to the rocker seat front lifting sliding support in the vertical direction; the rocker seat front lifting left chain fixed on the rocker seat front lifting left slide rail extends in the vertical direction and meshes with the rocker seat front lifting left sprocket; the rocker seat front lifting right chain fixed on the rocker seat front lifting right slide rail extends in the vertical direction and meshes with the rocker seat front lifting right sprocket; the rocker seat front lifting left connector fixed on the top of the rocker seat front lifting left slide rail and the rocker seat front lifting right connector fixed on the top of the rocker seat front lifting right slide rail are rotatably connected to the two front support points of the rocker seat frame, respectively.

[0013] Thus, by driving the left bearing of the front lifting of the rocker seat to rotate, the left and right sprockets of the front lifting of the rocker seat are driven to rotate, which in turn drive the left and right slide rails of the front lifting of the rocker seat to rise and fall through the left and right chains of the front lifting of the rocker seat, respectively. Then, the front support point of the rocker seat frame is driven to rise and fall through the left and right connecting parts of the front lifting of the rocker seat.

[0014] Preferably, the bottom rear end of the rocker seat frame is provided with two rear support points distributed on the left and right sides;

[0015] The rocker seat rear lifting mechanism includes: a rocker seat rear lifting bearing, a rocker seat rear lifting left slide plate, and a rocker seat rear lifting right slide plate, all fixed to the seat bracket; a rocker seat rear lifting output shaft rotatably connected to the rocker seat rear lifting bearing; one end of the left linkage mechanism assembly and one end of the right linkage mechanism assembly are respectively fixedly connected to both ends of the rocker seat rear lifting output shaft; the other end of the left linkage mechanism assembly is rotatably connected to the rocker seat rear lifting left sliding sleeve, which is slidably mounted on the rocker seat rear lifting left slide plate; the other end of the right linkage mechanism assembly is rotatably connected to the rocker seat rear lifting right sliding sleeve, which is slidably mounted on the rocker seat rear lifting right slide plate; and the top ends of the rocker seat rear lifting left and right sliding sleeves are respectively rotatably connected to the two rear support points of the rocker seat cushion frame.

[0016] Thus, by driving the rear lifting output shaft of the rocker seat to rotate, the left and right linkage mechanism components move, which in turn causes the left and right sliding sleeves of the rear lifting seat to rise and fall on the left and right sliding plates of the rear lifting seat, respectively, and then causes the rear fulcrum of the rocker seat pad to move up and down.

[0017] The second technical problem to be solved by this utility model is to provide a fitness exercise chair.

[0018] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0019] A fitness exercise chair, characterized in that: it is equipped with the aforementioned rocker seat mechanism assembly.

[0020] Preferably, the armrests of the fitness chair are equipped with human body sensors. Therefore, the controller can use the sensor signals to control whether the front and rear lifting mechanisms of the seat stop operating. That is, when a user is exercising on the seat cushion, if the user's hands are on the armrests and the human body sensors detect the user's hands, the front and rear lifting mechanisms will operate normally, allowing the user to exercise normally. However, if either hand is released from the armrest and the human body sensors fail to detect both hands simultaneously, the front and rear lifting mechanisms will stop operating to ensure user safety.

[0021] Preferably, the fitness chair is equipped with a level. This allows the level to be used to determine if the seat cushion is level, and the front and rear lifting mechanisms can be used to adjust the levelness and comfort of the seat cushion.

[0022] As a preferred embodiment of this utility model: see Figures 4 to 6The fitness chair is equipped with a multi-output gearbox, which includes: at least one clutch; a gearbox worm gear driven by a power motor is rotatably mounted on the gearbox housing; and the transmission gear of the rocker front lifting mechanism, which drives the rocker front lifting mechanism, can independently achieve power transmission and power separation from the gearbox worm gear through one of the clutches.

[0023] The transmission gear of the rocker seat front lifting mechanism can be flexibly arranged according to the installation space of the fitness chair to provide power to the rocker seat front lifting mechanism. Preferably, this utility model is as follows: [See details] Figure 4 The transmission gear of the rocker front lifting mechanism drives the rocker front lifting worm wheel fixed on the rocker front lifting output shaft to rotate through the worm gear mechanism, thereby driving the rocker front lifting output shaft to rotate.

[0024] Therefore, by controlling the clutch's engagement / disengagement state, the working and stopping states of the rocker seat's front lifting mechanism can be switched, and by adding a clutch, the same power motor can be used to provide power and disconnect power for other functions of the fitness chair.

[0025] Preferred: See Figure 6 The clutch comprises: a clutch motor body and a clutch slide rod fixed inside a gearbox housing; a motor shaft of the clutch motor and a clutch screw fixedly connected coaxially; a clutch screw and a clutch slider slidably mounted on the clutch slide rod in a threaded engagement, such that the clutch motor can drive a clutch transmission sleeve fixedly mounted on the clutch slider to slide between an engaged position and a disengaged position via the clutch screw; the clutch transmission sleeve and the clutch transmission rod simultaneously engage in sliding engagement and gear engagement; and the clutch transmission rod and the gearbox worm gear form a worm gear engagement.

[0026] The clutch corresponding to the transmission gear of the rocker front lifting mechanism is engaged with the transmission gear of the rocker front lifting mechanism when its clutch transmission sleeve is in the engaged position, and disengaged from the transmission gear of the rocker front lifting mechanism when its clutch transmission sleeve is in the disengaged position.

[0027] As a preferred embodiment of this utility model: see Figures 7 to 9 The fitness chair also includes a muscle stretching mechanism assembly, and the chair frame is fixed to the chair frame base plate;

[0028] The muscle stretching mechanism assembly includes: a leg muscle stretching translation mechanism, a leg muscle stretching rotation drive mechanism, and a leg muscle stretching lifting rod. The rear end of the leg muscle stretching lifting rod is fixed with a leg muscle stretching lifting rod pivot extending in the left and right direction, and the front end of the leg muscle stretching lifting rod is fixed with a leg muscle stretching mounting component. Both ends of the leg muscle stretching mounting component are respectively rotatably mounted with a leg muscle stretching roller extending in the left and right direction.

[0029] The leg muscle stretching translation mechanism is installed on the bottom plate of the seat outer frame, the leg muscle stretching rotation drive mechanism is installed on the leg muscle stretching translation mechanism, and the leg muscle stretching lifting rod pivot is installed in the leg muscle stretching rotation drive mechanism, so that: the leg muscle stretching translation mechanism can drive the leg muscle stretching rotation drive mechanism to move in the front and back direction, and the leg muscle stretching rotation drive mechanism can drive the leg muscle stretching lifting rod to rotate around the leg muscle stretching lifting rod pivot within an acute angle range.

[0030] Therefore, the working principle and usage of the leg muscle stretching mechanism assembly of this utility model are as follows:

[0031] When the user is seated with both feet resting on the two leg stretch rollers (or alternatively, with the calves of both legs resting on the two leg stretch rollers), there are two ways to perform leg stretching exercises:

[0032] Method 1: By controlling the leg muscle stretching translation mechanism to repeatedly drive the leg muscle stretching rotation drive mechanism, the leg muscle stretching lifting rod, and the two leg muscle stretching rollers to perform forward and backward translational movements, and simultaneously controlling the leg muscle stretching rotation drive mechanism to repeatedly drive the leg muscle stretching lifting rod and the two leg muscle stretching rollers to perform swinging movements, combined with the rolling movement of the leg muscle stretching rollers under the user's feet, the user's legs can simultaneously experience a compound movement composed of the translation and swinging of the leg muscle stretching lifting rod and the rolling of the leg muscle stretching rollers. The user's legs resist this compound movement to obtain the exercise effect of flexing and extending the knees and stretching the leg muscles.

[0033] Method 2: By controlling only the leg muscle stretching translation mechanism to repeatedly drive the leg muscle stretching rotation drive mechanism, the leg muscle stretching lifting rod, and the two leg muscle stretching rollers to move back and forth in a translational motion, combined with the rolling motion of the leg muscle stretching rollers under the user's feet, the user's legs can obtain the exercise effect of activating the lower limb joints.

[0034] Additionally, when used as a regular seat, rotating the leg stretch lever to its lowest position allows the two leg stretch rollers to be used as foot pedals.

[0035] Preferred: See Figures 7 to 10The leg muscle stretching translation mechanism includes: two leg muscle stretching track rods, each extending in the front-to-back direction and fixed to the base plate of the seat outer frame via leg muscle stretching track rod fixing members; a leg muscle stretching movable seat, slidable in the front-to-back direction, placed on the base plate of the seat outer frame; and multiple leg muscle stretching guide track wheels, which roll in cooperation with the leg muscle stretching track rods, installed on the left and right sides of the leg muscle stretching movable seat. Furthermore, the gearbox housing is fixed to the base plate of the seat outer frame via a seat bracket; the rear drive shaft of the leg muscle stretching mechanism is mounted on the base plate of the seat outer frame via a rear bearing; and the front drive shaft of the leg muscle stretching mechanism (not shown in the figure) is mounted on the seat via a front bearing. On the outer frame base plate, the output shaft of the leg muscle stretching gearbox is fixed with a first leg muscle stretching sprocket. The first leg muscle stretching sprocket, through a first leg muscle stretching chain (not shown in the figure), forms a sprocket and chain transmission mechanism with a second leg muscle stretching sprocket fixed on the rear transmission shaft of the leg muscle stretching gearbox. The third leg muscle stretching sprocket, fixed on the rear transmission shaft of the leg muscle stretching gearbox, forms a sprocket and chain transmission mechanism with a fourth leg muscle stretching sprocket fixed on the front transmission shaft of the leg muscle stretching gearbox, through a second leg muscle stretching chain (not shown in the figure). A section of the second leg muscle stretching chain is fixedly connected to the leg muscle stretching movable seat. The leg muscle stretching rotation drive mechanism is mounted on the leg muscle stretching movable seat.

[0036] Thus, by driving the output shaft of the leg muscle stretching gearbox to rotate, the sprocket and chain transmission mechanism consisting of the first leg muscle stretching sprocket, the first leg muscle stretching chain, and the second leg muscle stretching sprocket drives the rear transmission shaft of the leg muscle stretching to rotate. Then, the sprocket and chain transmission mechanism consisting of the third leg muscle stretching sprocket, the second leg muscle stretching chain, and the fourth leg muscle stretching sprocket drives the second leg muscle stretching chain to move. Finally, the leg muscle stretching moving seat and the leg muscle stretching rotation drive mechanism mounted on it move back and forth along the two leg muscle stretching track rods.

[0037] In addition, the second output shaft of the leg muscle stretching gearbox can drive a gear transmission mechanism, and the output gear of the gear transmission mechanism drives the seat back to adjust its angle.

[0038] The leg muscle stretching rotation drive mechanism includes: the body of the leg muscle stretching rotation drive motor and the leg muscle stretching rotation gearbox housing, which are fixed on the leg muscle stretching movable seat. The motor shaft of the leg muscle stretching rotation drive motor and the leg muscle stretching lifting rod shaft extend into the leg muscle stretching rotation gearbox housing. The leg muscle stretching lifting rod shaft is connected to the leg muscle stretching rotation gearbox housing through a leg muscle stretching rotation gearbox bearing. The motor shaft of the leg muscle stretching rotation drive motor is connected to the leg muscle stretching lifting rod shaft through a leg muscle stretching rotation gearbox gear transmission mechanism located inside the leg muscle stretching rotation gearbox housing.

[0039] Therefore, by driving the motor shaft of the leg muscle stretching rotation drive motor to rotate, the leg muscle stretching lifting rod shaft is driven to rotate through the gear transmission mechanism of the leg muscle stretching rotation gearbox, which in turn drives the leg muscle stretching lifting rod to rotate around the leg muscle stretching lifting rod shaft within an acute angle range.

[0040] Preferably, the leg muscle stretching roller is a massage roller with multiple protrusions on its circumference, so as to massage the user's feet while performing leg muscle stretching exercises; the bottom of the leg muscle stretching mounting piece is equipped with a leg muscle stretching auxiliary caster, so that when performing leg muscle stretching exercises in method two, the leg muscle stretching auxiliary caster can sit on the ground, reducing the pressure between the leg muscle stretching rotation drive mechanism and the leg muscle stretching lifting rod, and extending the service life.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] First, this utility model includes a rocker seat frame QZ1, a rocker seat cushion frame QZ2, a rocker front lifting mechanism QSQ, and a rocker rear lifting mechanism QSH. When the user sits on the seat cushion ZY3 and holds onto the armrests, the rocker front lifting mechanism QSQ and the rocker rear lifting mechanism QSH are simultaneously controlled to repeatedly drive the lifting and lowering. This allows the user to experience the combined motion of the rocker seat frame QZ1 and the rocker seat cushion frame QZ2. The user needs to exert force to resist this combined motion to remain seated on the seat cushion ZY3, thus achieving high-efficiency movement on the seat. Therefore, this utility model can function as a conventional seat while also enabling high-efficiency movement on the seat.

[0043] Secondly, the front lifting mechanism QSQ and the rear lifting mechanism QSH of the rocker seat adopted in this utility model have the advantages of strong power and high reliability.

[0044] Third, this utility model is equipped with a multi-output gearbox CL. By controlling the engagement and disengagement of the clutch CLL, the working and stopping states of the rocker seat front lifting mechanism QSQ can be switched. Furthermore, by adding a clutch CLL, the same power motor CL1 can provide power and disconnect power for other functions of the fitness chair.

[0045] Fourth, this utility model includes a leg muscle stretching translation mechanism TJP, a leg muscle stretching rotation drive mechanism TJX, a leg muscle stretching lifting rod TJ1, a leg muscle stretching lifting rod pivot TJ2, a leg muscle stretching mounting component TJ3, and leg muscle stretching rollers TJ4. When the user sits on the seat and places both feet on the two leg muscle stretching rollers TJ4, two types of leg muscle stretching exercises can be achieved by controlling the leg muscle stretching translation mechanism TJP individually or simultaneously controlling the leg muscle stretching rotation drive mechanism TJX. Therefore, this utility model can function as a conventional seat while also allowing the user to perform two types of leg muscle stretching exercises while seated. Thus, combined with the movement of the rocker seat assembly, it can provide the user with a more comprehensive full-body exercise. Attached Figure Description

However, the scope of protection of the claims of the present invention is not limited to the following embodiments. For those skilled in the art, all other embodiments obtained without creative effort without departing from the inventive concept of the present invention are within the scope of protection of the present invention.

[0058] In the description of this utility model, it should be clarified that the directional terms "up, down, front, back, left, right" are only relative concepts in terms of location. They are used to facilitate the description of this utility model or to simplify the description, and are not intended to indicate or imply a specific location that this utility model must have. Therefore, they should not be construed as limitations on this utility model.

[0059] Example 1

[0060] like Figures 1 to 4 As shown, the present invention discloses a seesaw seat mechanism assembly, including: seesaw seat frame QZ1, seesaw seat cushion frame QZ2, seesaw seat front lifting mechanism QSQ and seesaw seat rear lifting mechanism QSH;

[0061] The front lifting mechanism QSQ and the rear lifting mechanism QSH of the rocker seat are both installed on the seat bracket ZY2, which is fixed inside the seat outer frame ZY1.

[0062] The rear support point QZ1h of the rocker seat frame QZ1 is connected to the outer frame ZY1 of the seat to form a rotational engagement with the horizontally arranged pivot. The front lifting mechanism QSQ of the rocker seat can drive the front support point QZ1q of the rocker seat frame QZ1 to perform lifting and lowering movements.

[0063] The rocker seat cushion frame QZ2 is used to install the seat cushion ZY3. The front fulcrum QZ2q of the rocker seat cushion frame QZ2 is connected to the rocker seat frame QZ1 and simultaneously forms a rotational fit with the horizontally arranged pivot and a sliding fit along the straight line. The rocker seat rear lifting mechanism QSH can drive the rear fulcrum QZ2h of the rocker seat cushion frame QZ2 to move up and down. The aforementioned straight line is generally preferred to be the front and back direction of the seat, but other straight lines can also be used.

[0064] The working principle and usage of the seesaw seat mechanism assembly in this utility model are as follows:

[0065] When a user sits on the seat cushion ZY3 and holds onto the armrests, the lifting mechanism QSQ and the rear lifting mechanism QSH of the rocker seat are repeatedly controlled to drive the lifting motion. This causes the rocker seat frame QZ1 to oscillate within an acute angle range around its rear fulcrum QZ1h, while the rocker seat cushion frame QZ2 oscillates within an acute angle range around its front fulcrum QZ2q and simultaneously performs a translational motion along a straight line. The aforementioned acute angle range is generally 0° to 25°. As a result, the user is simultaneously subjected to the combined motion of the rocker seat frame QZ1 and the rocker seat cushion frame QZ2. The user needs to exert force to resist this combined motion to remain seated on the seat cushion ZY3, thus achieving high-efficiency exercise on the seat. Experiments have shown that the fingers, palms, arms, abdominal muscles, and internal organs can all be effectively exercised.

[0066] The above is the basic implementation method of this embodiment one, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0067] Preferably, the bottom front end of the seesaw frame QZ1 is provided with two front support points QZ1q distributed on the left and right sides;

[0068] The rocker seat front lifting mechanism QSQ includes: a rocker seat front lifting left bearing QSQ1z, a rocker seat front lifting right bearing QSQ1y, and a rocker seat front lifting sliding support QSQ2, all fixed to the seat bracket ZY2. The two ends of the rocker seat front lifting output shaft QSQ3 are rotatably connected to the rocker seat front lifting left bearing QSQ1z and the rocker seat front lifting right bearing QSQ1y, respectively, and the rocker seat front lifting output shaft QSQ3 is fixedly fitted with a rocker seat front lifting left sprocket QSQ4z and a rocker seat front lifting right sprocket QSQ4y; the rocker seat front lifting left slide rail QSQ5z and the rocker seat front lifting right slide rail QSQ5y are respectively connected to the rocker seat front lifting sliding support QSQ2 along the upper edge... The left lifting chain QSQ6z, fixed on the left lifting slide rail QSQ5z, extends vertically and meshes with the left lifting sprocket QSQ4z. The right lifting chain QSQ6y, fixed on the right lifting slide rail QSQ5y, extends vertically and meshes with the right lifting sprocket QSQ4y. The left lifting connector QSQ7z and the right lifting connector QSQ7y, fixed on the top of the left lifting slide rail QSQ5z and the top of the right lifting slide rail QSQ5y, are rotatably connected to the two front fulcrums QZ1q of the rocker frame QZ1.

[0069] Thus, by driving the left bearing QSQ1z of the front lifting of the rocker seat to rotate, the left sprocket QSQ4z and the right sprocket QSQ4y of the front lifting of the rocker seat are driven to rotate. Then, the left chain QSQ6z and the right chain QSQ6y of the front lifting of the rocker seat drive the left slide rail QSQ5z and the right slide rail QSQ5y of the front lifting of the rocker seat to rise and fall respectively. Then, the left connecting piece QSQ7z and the right connecting piece QSQ7y of the front lifting of the rocker seat drive the front fulcrum QZ1q of the rocker seat frame QZ1 to move up and down.

[0070] Preferably, the bottom rear end of the rocker seat frame QZ2 is provided with two rear support points QZ2h distributed on the left and right sides;

[0071] The rocker seat rear lifting mechanism QSH includes: a rocker seat rear lifting bearing QSH1, a rocker seat rear lifting left sliding plate QSH2z, and a rocker seat rear lifting right sliding plate QSH2y, all fixed to the seat bracket ZY2. The rocker seat rear lifting output shaft QSH3 is rotatably connected to the rocker seat rear lifting bearing QSH1. One end of the left linkage mechanism assembly QSH4z and one end of the right linkage mechanism assembly QSH4y are respectively fixedly connected to both ends of the rocker seat rear lifting output shaft QSH3. The other end of the left linkage mechanism assembly QSH4z is rotatably connected to the rocker seat rear lifting left sliding sleeve QSH5z, which is slidably mounted on the rocker seat rear lifting left sliding plate QSH2z. The other end of the right linkage mechanism assembly QSH4y is rotatably connected to the rocker seat rear lifting right sliding sleeve QSH5y, which is slidably mounted on the rocker seat rear lifting right sliding plate QSH2y. The top ends of the rocker seat rear lifting left sliding sleeve QSH5z and the top ends of the rocker seat rear lifting right sliding sleeve QSH5y are respectively rotatably connected to the two rear support points QZ2h of the rocker seat cushion frame QZ2.

[0072] Thus, by driving the rear lifting output shaft QSH3 of the rocker seat to rotate, the left linkage mechanism assembly QSH4z and the right linkage mechanism assembly QSH4y move, which in turn drives the left sliding sleeve QSH5z and the right sliding sleeve QSH5y of the rear lifting seat to rise and fall on the left sliding plate QSH2z and the right sliding plate QSH2y of the rear lifting seat, respectively, and then drives the rear fulcrum QZ2h of the rocker seat pad QZ2 to move up and down.

[0073] Example 2

[0074] like Figures 1 to 4 As shown, this utility model also discloses a fitness exercise chair, which is equipped with the seesaw seat mechanism assembly described in Embodiment 1.

[0075] The above is the basic implementation method of this embodiment two, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0076] Preferably, the armrests of the fitness chair are equipped with human body sensors. Therefore, the controller can use the sensing signals from the human body sensors to control whether the front lifting mechanism QSQ and the rear lifting mechanism QSH stop operating. That is, when a user is exercising on the seat cushion ZY3, if the user's hands are on the armrests and the human body sensors detect the user's hands, the front lifting mechanism QSQ and the rear lifting mechanism QSH will operate normally, allowing the user to exercise normally. However, if either hand of the user releases the armrest and the human body sensors fail to detect both hands simultaneously, the front lifting mechanism QSQ and the rear lifting mechanism QSH will stop operating to ensure the user's safety.

[0077] Preferably, the fitness chair is equipped with a level. This allows the level to determine whether the seat cushion ZY3 is level, and the front lifting mechanism QSQ and the rear lifting mechanism QSH to adjust the levelness and comfort of the seat cushion ZY3.

[0078] Example 3

[0079] Based on the above embodiment two, this embodiment three also adopts the following preferred implementation method:

[0080] See Figures 4 to 6 The fitness chair is equipped with a multi-output gearbox CL, which includes: at least one clutch CLL; a gearbox worm gear CL2 driven by a power motor CL1 is rotatably mounted on a gearbox housing CL3; and a front lifting mechanism transmission gear CL4 for driving the front lifting mechanism QSQ can achieve power transmission and power separation from the gearbox worm gear CL2 through one of the clutches CLL.

[0081] Among them, the transmission gear CL4 of the rocker seat front lifting mechanism can be flexibly arranged according to the installation space of the fitness chair to provide power to the rocker seat front lifting mechanism QSQ. Preferably, this utility model is as follows: See Figure 4 The transmission gear CL4 of the rocker front lifting mechanism drives the rocker front lifting worm gear QSQ8, which is fixed on the rocker front lifting output shaft QSQ3, to rotate through the worm gear mechanism, thereby driving the rocker front lifting output shaft QSQ3 to rotate.

[0082] Therefore, by controlling the engagement and disengagement of the clutch CLL, the working and stopping states of the rocker seat front lifting mechanism QSQ can be switched, and by adding the clutch CLL, the same power motor CL1 can provide power and disconnect power for other functions of the fitness seat.

[0083] The above is the basic implementation method of this embodiment three, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0084] Preferred: See Figure 6 The clutch CLL comprises: the body of the clutch motor CLL1 and the clutch slide CLL2 fixed inside the gearbox housing CL3; the motor shaft of the clutch motor CLL1 is coaxially fixedly connected to the clutch screw CLL3; the clutch screw CLL3 is threadedly engaged with the clutch slider CLL4 slidably mounted on the clutch slide CLL2, so that the clutch motor CLL1 can drive the clutch transmission sleeve CLL5 fixedly mounted on the clutch slider CLL4 to slide between the engagement position and the disengagement position through the clutch screw CLL3; the clutch transmission sleeve CLL5 and the clutch transmission rod CLL6 are simultaneously in sliding engagement and gear engagement; the clutch transmission rod CLL6 and the gearbox worm CL2 form a worm gear engagement.

[0085] The clutch CLL corresponding to the transmission gear CL4 of the rocker front lifting mechanism is engaged with the transmission gear CL4 when its clutch transmission sleeve CLL5 is in the engaged position, and disengaged from the transmission gear CL4 when its clutch transmission sleeve CLL5 is in the disengaged position.

[0086] Example 4

[0087] Based on the above-described Embodiment 2 or Embodiment 3, this Embodiment 4 further adopts the following preferred implementation method:

[0088] See Figures 7 to 9 The fitness chair also includes a muscle stretching mechanism assembly, and the chair outer frame ZY1 is fixed to the chair outer frame base plate DB;

[0089] The muscle stretching mechanism assembly includes: a leg muscle stretching translation mechanism TJP, a leg muscle stretching rotation drive mechanism TJX, and a leg muscle stretching lifting rod TJ1. The rear end of the leg muscle stretching lifting rod TJ1 is fixed with a leg muscle stretching lifting rod pivot TJ2 extending in the left-right direction, and the front end of the leg muscle stretching lifting rod TJ1 is fixed with a leg muscle stretching mounting component TJ3. Both ends of the leg muscle stretching mounting component TJ3 are respectively rotatably mounted with a leg muscle stretching roller TJ4 extending in the left-right direction.

[0090] The leg muscle stretching translation mechanism TJP is installed on the seat outer frame bottom plate DB, the leg muscle stretching rotation drive mechanism TJX is installed on the leg muscle stretching translation mechanism TJP, and the leg muscle stretching lifting rod pivot TJ2 is installed in the leg muscle stretching rotation drive mechanism TJX, so that: the leg muscle stretching translation mechanism TJP can drive the leg muscle stretching rotation drive mechanism TJX to move in the front and back direction, and the leg muscle stretching rotation drive mechanism TJX can drive the leg muscle stretching lifting rod TJ1 to rotate around the leg muscle stretching lifting rod pivot TJ2 within an acute angle range.

[0091] Therefore, the working principle and usage of the leg muscle stretching mechanism assembly of this utility model are as follows:

[0092] When the user is seated with both feet resting on the two TJ4 leg muscle stretching rollers (or alternatively, with the calves of both legs resting on the TJ4 leg muscle stretching rollers), there are two ways to perform leg muscle stretching exercises:

[0093] Method 1: By controlling the leg muscle stretching translation mechanism TJP to repeatedly drive the leg muscle stretching rotation drive mechanism TJX, the leg muscle stretching lifting rod TJ1, and the two leg muscle stretching rollers TJ4 to perform forward and backward translational movements, and simultaneously controlling the leg muscle stretching rotation drive mechanism TJX to repeatedly drive the leg muscle stretching lifting rod TJ1 and the two leg muscle stretching rollers TJ4 to perform swinging movements, combined with the rolling movement of the leg muscle stretching rollers TJ4 under the user's feet, the user's legs can simultaneously be subjected to the combined action of the translation and swinging of the leg muscle stretching lifting rod TJ1 and the rolling of the leg muscle stretching rollers TJ4. The user's legs resist this combined movement to obtain the exercise effect of flexing and extending the knees and stretching the leg muscles.

[0094] Method 2: By controlling the leg muscle stretching translation mechanism TJP to repeatedly drive the leg muscle stretching rotation drive mechanism TJX, the leg muscle stretching lifting rod TJ1, and the two leg muscle stretching rollers TJ4 to perform forward and backward translational movements, combined with the rolling movement of the leg muscle stretching rollers TJ4 under the user's feet, the user's legs can achieve the effect of exercising and activating the lower limb joints.

[0095] In addition, when used as a regular seat, rotating the leg stretch lever TJ1 to the lowest position allows the two leg stretch rollers TJ4 to be used as foot pedals.

[0096] The above is the basic implementation method of this embodiment four, and further optimizations, improvements and limitations can be made based on this basic implementation method:

[0097] Preferred: See Figures 7 to 10The leg muscle stretching translation mechanism TJP includes: two leg muscle stretching track rods TJP1, each fixed to the seat outer frame base plate DB via leg muscle stretching track rod fixing parts TJP2 extending in the front-back direction; a leg muscle stretching movable seat TJP3, slidably mounted on the seat outer frame base plate DB in the front-back direction; and multiple leg muscle stretching guide track wheels TJP4, which roll in cooperation with the leg muscle stretching track rods TJP1, installed on the left and right sides of the leg muscle stretching movable seat TJP3. Furthermore, the leg muscle stretching gearbox TJC's housing is fixed to the seat outer frame base plate DB via a seat bracket ZY2; the rear drive shaft TJP5 is mounted on the seat outer frame base plate DB via a rear bearing TJP6; and the front drive shaft (not shown in the figure) is mounted via a front bearing TJP7. Mounted on the base plate DB of the seat outer frame, the output shaft of the leg muscle stretching gearbox TJC is fixed with a first leg muscle stretching sprocket TJP8. The first leg muscle stretching sprocket TJP8, via a first leg muscle stretching chain (not shown in the figure), forms a sprocket and chain transmission mechanism with a second leg muscle stretching sprocket TJP9 fixed on the rear drive shaft TJP5. A third leg muscle stretching sprocket TJP10, fixed on the rear drive shaft TJP5, via a second leg muscle stretching chain (not shown in the figure), forms a sprocket and chain transmission mechanism with a fourth leg muscle stretching sprocket TJP11 fixed on the front drive shaft. A section of the second leg muscle stretching chain is fixedly connected to the leg muscle stretching movable seat TJP3. The leg muscle stretching rotary drive mechanism TJX is mounted on the leg muscle stretching movable seat TJP3.

[0098] Thus, by driving the output shaft of the leg muscle stretching gearbox TJC to rotate, the sprocket and chain transmission mechanism consisting of the first leg muscle stretching sprocket TJP8, the first leg muscle stretching chain, and the second leg muscle stretching sprocket TJP9 drives the rear transmission shaft TJP5 to rotate. Then, the sprocket and chain transmission mechanism consisting of the third leg muscle stretching sprocket TJP10, the second leg muscle stretching chain, and the fourth leg muscle stretching sprocket TJP11 drives the second leg muscle stretching chain to move. Finally, the leg muscle stretching moving seat TJP3 and the leg muscle stretching rotary drive mechanism TJX mounted on it move back and forth along the two leg muscle stretching track rods TJP1.

[0099] In addition, the second output shaft of the leg muscle stretching gearbox TJC can drive the gear transmission mechanism, and the output gear TJC1 of the gear transmission mechanism drives the seat back to adjust the angle.

[0100] The leg muscle stretching rotary drive mechanism TJX includes: the body of the leg muscle stretching rotary drive motor TJX1 and the leg muscle stretching rotary gearbox housing TJX2, which are fixed on the leg muscle stretching movable seat TJP3. The motor shaft of the leg muscle stretching rotary drive motor TJX1 and the leg muscle stretching lifting rod shaft TJ2 respectively extend into the leg muscle stretching rotary gearbox housing TJX2. The leg muscle stretching lifting rod shaft TJ2 is connected to the leg muscle stretching rotary gearbox housing TJX2 through the leg muscle stretching rotary gearbox bearing TJX3. The motor shaft of the leg muscle stretching rotary drive motor TJX1 is connected to the leg muscle stretching lifting rod shaft TJ2 through the leg muscle stretching rotary gearbox gear transmission mechanism TJX4 located inside the leg muscle stretching rotary gearbox housing TJX2.

[0101] Thus, by driving the motor shaft of the leg muscle stretching rotation drive motor TJX1 to rotate, the leg muscle stretching lifting rod shaft TJ2 is driven to rotate through the gear transmission mechanism TJX4 of the leg muscle stretching rotation gearbox, which in turn drives the leg muscle stretching lifting rod TJ1 to rotate around the leg muscle stretching lifting rod shaft TJ2 within an acute angle range.

[0102] Preferably, the leg muscle stretching roller TJ4 is a massage roller with multiple protrusions on its circumference, so as to massage the user's feet while performing leg muscle stretching exercises; the bottom of the leg muscle stretching mounting component TJ3 is equipped with a leg muscle stretching auxiliary caster TJ5, so that when performing leg muscle stretching exercises in mode two, the leg muscle stretching auxiliary caster TJ5 can sit on the ground, reducing the pressure between the leg muscle stretching rotation drive mechanism TJX and the leg muscle stretching lifting rod TJ1, and extending the service life.

[0103] This utility model is not limited to the specific embodiments described above. Based on the above content and in accordance with the common technical knowledge and conventional methods in the field, without departing from the basic technical idea of ​​this utility model, other equivalent modifications, substitutions or alterations can be made to this utility model, all of which fall within the protection scope of this utility model.
