Description

Technical Field

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

[0002] With the prosperity and development of modern society, the pace of life of modern people is accelerating, and the pressure is increasing. In addition, the time for exercise is decreasing, and people usually eat more greasy food, which leads to poor blood circulation, and the incidence of related cardiovascular diseases is also increasing. As people pay more and more attention to health, when personal exercise is not up to standard, many people can only achieve the effect of promoting blood circulation and metabolism through massage. As a massage product, massage chairs are being favored by more and more people, and there are more and more demands for massage. Not only do they require massage from head to toe, but they also require that the body posture can be adjusted at will during massage to achieve the best massage effect. Especially when massaging during the short lunch break at noon, there will be obvious stiffness after waking up. This is because the existing massage chair has no way to adjust the backrest state, and the body massage posture is not fully stretched.

[0003] Existing massage chairs can be roughly divided into two types: one is a linear rail, which can only perform back massage, but the backrest position can be relatively adjusted in angle; the other is a more popular L-shaped rail, which can not only perform back massage, but also buttocks massage, but its backrest position and seat position are fixed angles, and it is impossible to adjust the upper body posture alone. This leads to long-term massage, and the fixed massage posture will also cause fatigue, and it is impossible to completely relax the massage. At the same time, when the massage chair is in an upright state, the user will have a noticeable foreign body sensation and poor body sensation due to the presence of the massage movement. Summary of the invention

[0004] The present invention proposes a massage chair in view of the deficiencies in the prior art, thereby solving the problem that during the massage process, the chair frame posture of the prior art massage chair cannot be adjusted, which causes fatigue caused by maintaining the same posture, and the user will have an obvious foreign body sensation when sitting on the massage chair in an upright position due to the presence of a massage movement.

[0005] The present invention provides a massage chair, comprising a base, a back frame, a seat frame, a driving device, a back frame swing rod and a seat frame swing rod;

[0006] The back frame includes a seat and a backrest, wherein the backrest is arranged corresponding to the waist and back of the user; the seat frame is used for the user to sit on, and the seat frame is located above the seat and in front of the backrest;

[0007] The bottom ends of the back frame swing rod and the seat frame swing rod are both hinged on the base and spaced apart on the base, the back frame swing rod is arranged close to the backrest portion of the back frame, and the seat frame swing rod is arranged close to the seat frame; the other end of the back frame swing rod is hinged to the backrest portion, the first end of the seat frame swing rod is hinged to the seat portion, the second end of the seat frame swing rod is hinged to the first end of the seat frame, and the second end of the seat frame is connected to the middle portion of the back frame swing rod;

[0008] The back frame swing rod, the back frame and the seat frame swing rod form a hinged four-bar mechanism, and the driving device is connected to the back frame swing rod and the base respectively;

[0009] The driving device contracts, driving the back frame swing rod to pull the back frame to move toward the seat frame, and driving the seat frame swing rod to pull the seat frame to move together, thereby adjusting the back frame from an upright state to a tilted state, and at the same time, changing the angle between the backrest and the seat frame.

[0010] By adopting the above technical scheme, the present invention can achieve the following technical effects: Compared with the prior art, the massage chair is provided with a back frame swing rod, a back frame and a seat frame swing rod to form a hinged four-bar mechanism, the bottom ends of the back frame swing rod and the seat frame swing rod are both hinged on the base and spaced on the base, the other end of the back frame swing rod is hinged to the backrest, the first end of the seat frame swing rod is hinged to the seat, the second end of the seat frame swing rod is hinged to the first end of the seat frame, and the second end of the seat frame is connected to the middle of the back frame swing rod; in this way, the driving device contracts, drives the back frame swing rod to pull the back frame to move in the direction of the seat frame, and drives the seat frame swing rod to pull the seat frame to move together, thereby adjusting the back frame from an upright state to a tilted state, and at the same time, changing the angle between the backrest and the seat frame. This structure not only satisfies the massage from the neck to the buttocks of the customer, but also can stretch the body posture during the back massage to make the user more comfortable, and can also make the adjustment angle between the backrest and the seat frame reach a nearly horizontal state, and cooperate with the ejection massage of the movement, so that the original muscle stretching effect can be optimized, so that the user can get a better massage effect.

[0019] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Combined with Figure 1-5 , an embodiment of the present invention provides a massage chair, comprising a base 1, a back frame 2, a seat frame 3, a driving device 4, a back frame swing rod 5 and a seat frame swing rod 6;

[0021] The back frame 2 includes a seat 21 and a backrest 22, wherein the backrest 22 is arranged corresponding to the waist and back of the user; the seat frame 3 is used for the user to sit on, and the seat frame 3 is located above the seat 21 and in front of the backrest 22; wherein the width of the back frame 2 is narrower than that of the seat frame 3.

[0022] The bottom ends of the back frame swing rod 5 and the seat frame swing rod 6 are both hinged on the base 1 and are spaced apart on the base 1. The back frame swing rod 5 is arranged close to the backrest 22 of the back frame 2, and the seat frame swing rod 6 is arranged close to the seat frame 3. The other end of the back frame swing rod 2 is hinged to the backrest 22, the first end of the seat frame swing rod 6 is hinged to the seat 21, the second end of the seat frame swing rod 6 is hinged to the first end of the seat frame 3, and the second end of the seat frame 3 is connected to the middle part of the back frame swing rod 5.

[0023] The back frame swing rod 5, the back frame 2 and the seat frame swing rod 6 form a hinged four-bar mechanism, and the driving device 4 is connected to the back frame swing rod 5 and the base 1 respectively;

[0024] The driving device 4 contracts, driving the back frame rocker arm 5 to pull the back frame to move toward the seat frame 3, and driving the seat frame rocker arm + pulling the seat frame 3 to move together, thereby adjusting the back frame 2 from an upright state to a tilted state, and at the same time, changing the angle between the backrest portion 22 and the seat frame 3.

[0025] In other words, this structure not only satisfies the customer's massage needs from the neck to the buttocks, but also can stretch the body posture during the reverse back massage to make the user more comfortable, and can also make the adjustment angle between the backrest and the seat frame reach a nearly horizontal state. Combined with the ejection massage of the movement, the original stretching effect can be optimized, allowing users to get better massage effects.

[0026] Further, in one example, Figure 3 As shown, it also includes a first connecting rod 7, one end of which is hinged to the second end of the seat frame 3, and the other end is hinged to the middle part of the back frame swing rod 5, so that the second end of the seat frame 3 is connected to the middle part of the back frame swing rod 5; when the driving device 4 contracts and the back frame swing rod 5 drives the seat frame 3 to rotate, the first connecting rod 7 is used to reduce the angle of rotation of the seat frame 3 following the back frame swing rod 5, so as to increase the angle between the backrest portion 22 and the seat frame 3.

[0027] The purpose of designing the first connecting rod in this way is that when the driving device is contracted, the angle at which the seat frame rotates following the back frame rocker arm can be offset by the rotation of the first connecting rod, so that the rotation angle of the seat frame is more stable and the user's riding is more stable. In addition, the back frame is driven by the driving device to tilt as much as possible, so that the angle between the seat frame and the back frame is increased and can be close to a horizontal state, so that the user's massage is more comfortable, and combined with the ejection massage of the movement, the stretching effect can be optimized, so that the user can get a better massage effect.

[0028] A first connecting rod is added to form a six-link mechanism, which has a simple structure and good economic benefits. It can not only massage the body from the neck to the buttocks, but also adjust the posture during massage to avoid physical discomfort caused by a fixed posture. It can also better ensure the stretchability of the body during a nap after the massage to achieve a better massage effect. On the other hand, when the massage chair is in an upright state, the movement can be well retracted in the guide rail assembly under the seat, and the user does not feel any foreign body sensation at all.

[0029] In addition, it should be noted that the position of the connecting rod can be changed, but the common point is that a six-rod combination is used to complete the reverse back and open the angle of the seat frame and the back frame, or the forward sliding four-bar mechanism is replaced with a guide rail and then a connecting rod is added to achieve the same action. The embodiments of the present invention do not make any assumptions about this.

[0030] Furthermore, in one example, it also includes a calf iron frame and a calf push rod (not shown in the figure), one end of the calf push rod is hinged to the front end of the base, and the other end is hinged to the calf iron frame, and the calf iron frame is hinged to the front end of the seat frame; the calf push rod drives the calf iron frame to rise or fall. In this way, when the back frame is turned over, the movement pushes out the massage, and the calf can swing up and down repeatedly, so that multiple parts of the user's body can be stretched, so that the user's massage effect is better.

[0031] Further, in one example, Figure 3 As shown, the seat 21 is provided with a front fixing rod 211, the first end of the seat frame swing rod 6 is hinged to the front fixing rod 211, one end of the front fixing rod 211 is fixed to the seat 21, and the other end is exposed above the seat 21. By setting the front fixing rod, when the seat frame is set above the seat of the back frame, there is a certain distance between them, which provides enough massage space for the seat frame to rotate with the back frame and for the massage movement to massage the user's buttocks. In addition, when the massage chair is not massaging, the massage movement can be stored in the seat of the back frame, so that when the user sits on the massage chair, there is no foreign body sensation on the back and the seat, and the user experience is better.

[0032] Further, in one example, Figure 3 As shown, the backrest 22 is provided with a rear fixing rod 221, and the other end of the back frame swing rod 5 is hinged to the rear fixing rod 221, and one end of the rear fixing rod 221 is fixed to the backrest 22, and the other end is exposed below the backrest 22. By setting the rear fixing rod, the tilting angle of the backrest can be increased, thereby making the angle between the seat frame and the backrest larger after the backrest is tilted. In another example, the rear fixing rod can be tilted toward the backrest to further increase the tilting angle of the backrest, so that the adjusted chair frame is closer to a horizontal state, and the forward movement distance of the entire chair frame can be increased, so that the chair frame is closer to the zero wall, saving space.

[0033] Further, in one example, Figure 3 As shown, the base 1 is also fixed with a front support rod 11 and a rear support rod 12, the bottom end of the seat frame swing rod 6 is hinged to the front support rod 11, and the bottom end of the back frame swing rod 5 is hinged to the rear support rod 12. In this way, the seat frame and the back frame can move forward a longer distance, closer to the zero-wall design, and further increase the angle between the seat frame and the back frame.

[0034] Furthermore, in one example, a guide rail is provided on the back frame, a reciprocating massage mechanism is provided on the guide rail, a massage swing arm is provided on the massage mechanism, and the massage swing arm can extend in a direction away from the massage mechanism, and when the massage mechanism moves to the seat, the massage swing arm can extend to a position close to or above the seat frame to massage the user;

[0035] It also includes a control device, which controls the movement of the massage movement and the driving device.

[0036] Furthermore, in one example, the driving device is any one of a push rod, an airbag assembly, an air cylinder, and an oil cylinder.

[0037] The structure and working principle of the massage chair of the present invention are described in detail below through a specific embodiment.

[0038] like Figure 1-5 As shown, the present invention provides a massage chair, including a base 1, a back frame 2, a seat frame 3, a first connecting rod 7, a driving device 4, a back frame swing rod 5 and a seat frame swing rod 6; wherein, the back frame 2 includes a seat portion 21 and a backrest portion 22, and the backrest portion 22 is arranged corresponding to the waist and back of the user; the seat frame 3 is used for the user to sit on, and the seat frame 3 is located above the seat portion 21 and in front of the backrest portion 22; and the width of the back frame 2 is narrower than that of the seat frame 3.

[0039] The bottom ends of the back frame swing rod 5 and the seat frame swing rod 6 are both hinged on the base 1 and are arranged at intervals on the base 1. The back frame swing rod 5 is arranged close to the backrest 22 of the back frame 2, and the seat frame swing rod 6 is arranged close to the seat frame 3; the other end of the back frame swing rod 5 is hinged to the backrest 22, the first end a of the seat frame swing rod 6 is hinged to the seat 21, the second end b of the seat frame swing rod 6 is hinged to the first end of the seat frame 3, the second end of the seat frame 3 is hinged to one end of the first connecting rod 7, and the other end of the first connecting rod 7 is hinged to the middle part of the back frame swing rod 5, so that the second end of the seat frame 3 is connected to the middle part of the back frame swing rod 5; the back frame swing rod 5, the back frame 2 and the seat frame swing rod 6 form a hinged four-bar mechanism, and the driving device 4 is respectively connected to the back frame swing rod 5 and the base 1;

[0040] The driving device 4 contracts, driving the back frame swing rod 5 to pull the back frame 2 to move toward the seat frame 3, and driving the seat frame swing rod 6 to pull the seat frame 3 to move together, thereby adjusting the back frame from an upright state to a tilted state, and at the same time, changing the angle between the backrest and the seat frame. When the driving device 4 contracts, when the back frame swing rod 5 drives the seat frame 3 to rotate, the first connecting rod 7 is used to reduce the angle of the seat frame 3 following the back frame swing rod 5 to increase the angle between the backrest 22 and the seat frame 3.

[0041] Among them, the main frames of the back frame, seat frame and base are all rigid. An L-shaped guide rail is arranged on the left and right sides of the back frame, and a rack is installed on the guide rail to guide the movement of the massage movement.

[0042] The shape of the L-shaped guide rail is basically L-shaped, but the difference between the embodiment of the present invention and the transmission L-shaped guide rail is that the L-shaped angle is opened wider. For example, the traditional guide rail is only 120 degrees, and the structural design of the embodiment of the present invention can make the angle between the seat frame and the back frame reach about 145 degrees. Of course, the specific design of this angle is designed according to different movement heights, and can be designed to different angles. In order to make the massage chair in an upright state and not working, the movement is hidden under the buttocks and does not affect the normal sitting feeling. When the movement moves to this point of the seat, the upper and lower massage wheels need to be below the plane of the seat frame, which will not affect the sitting feeling. On the other hand, when the back is reversed to the maximum angle, it is necessary to ensure that the front end angle of the guide rail is basically consistent with the angle of the seat frame, so that the movement can ensure uniform force when massaging the buttocks.

[0043] The driving device, in this example, uses a push rod, which is mainly used to drive the back frame swing rod to swing forward, realize the forward sliding and backward movement of the back frame, and thus achieve the effect of adjusting the angle of the back frame.

[0044] The second end of the seat frame rocker arm is hinged to the first end of the seat frame, and the second end of the seat frame is hinged to one end of the first connecting rod. Due to the existence of the first connecting rod, the angle of the seat frame sliding forward can be adjusted. When the driving device is contracted, the angle at which the seat frame rotates following the back frame rocker arm can be offset by the rotation of the first connecting rod, so that the rotation angle of the seat frame is more stable. The optimal forward sliding rotation of the seat frame is horizontal movement. Under the limitation of the first connecting rod, the user's riding is more stable, and the back frame tries to tilt as much as possible under the drive of the driving device, thereby realizing the opening of the angle between the back and the seat, which can be close to a horizontal state, and the user's massage is more comfortable. Combined with the ejection massage of the movement, the stretching effect can be optimized, allowing the user to get a better massage effect.

[0045] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
