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] Specifically, existing massage chairs can be roughly divided into two types: one is a massage chair with a linear guide rail, which can only perform back massage, but the backrest position can be adjusted relative to the seat; the other is a massage chair with a more popular L-shaped guide rail, which can not only perform back massage, but also buttocks massage, but its backrest position and seat position are fixed angles, and the upper body posture cannot be adjusted independently. Long-term fixed massage posture will also lead to fatigue, and a completely relaxing massage cannot be achieved. Summary of the invention

[0004] The present invention aims at the deficiencies of the prior art and proposes a massage chair, thereby solving the problems that the prior massage chair cannot perform full body massage and the massage posture cannot be adjusted.

[0005] The present invention provides a massage chair, comprising a base, a seat frame, a backrest frame, a push rod and a connecting rod; the base is provided with a guide rail, the backrest frame is reciprocatingly slidably arranged on the guide rail, the backrest frame comprises a backrest portion and a buttocks guide portion, the rear end of the seat frame is hinged to the backrest frame and is arranged above the buttocks guide portion, the first end of the connecting rod is hinged to the front end of the seat frame, and the second end of the connecting rod is hinged to the base at a first hinge point; the push rod comprises a guide rod and a slider, the slider is slidably arranged on the guide rod, one end of the push rod is hinged to the base at a second hinge point, and the slider is hinged to the buttocks guide portion of the backrest frame;

[0006] The slider slides on the guide rod in a direction away from the backrest portion, driving the backrest frame to slide on the guide rail in a direction toward the buttocks guide portion, so that the seat frame drives the connecting rod to swing away from the backrest portion with the first hinge point as a fulcrum, so that the angle between the seat frame and the backrest portion becomes larger.

[0007] By adopting the above technical scheme, the present invention can achieve the following technical effects: Compared with the prior art, the massage chair adopts a chair frame, a connecting rod structure and a guide rail, which not only satisfies the customer's massage from the neck to the buttocks, but also has a simple structure, and the posture can be adjusted during the massage, and the body posture can be stretched during the back massage to make the user more comfortable, and the backrest can be adjusted to a nearly horizontal angle, and the massage movement can be used with the ejection massage of the massage movement to achieve the best original stretching effect, so that the user can get a better massage effect. Therefore, the physical discomfort caused by the fixed posture is avoided, and the stretchability of the body can be better guaranteed when taking a nap after the massage. On the other hand, when the massage chair is in an upright state, the massage movement can be well retracted in the guide rail under the buttocks guide part, and the user can not feel the foreign body sensation at all, which further enhances the user's favorability.

DETAILED DESCRIPTION

[0017] 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.

[0018] Combined with Figure 1-7 As shown, an embodiment of the present invention provides a massage chair, including a base 1, a seat frame 2, a backrest frame 3, a push rod 4 and a connecting rod 5; a guide rail 11 is provided on the base 1, and the backrest frame 3 is reciprocatingly slidably arranged on the guide rail 11, and rollers 31 and a rotating shaft are coaxially arranged on both sides of the backrest frame 3; one end of the rotating shaft is rotatably connected to one end of the roller 31, and the other end of the rotating shaft is fixedly connected to the backrest frame 3; the roller 31 can slide in the corresponding guide rail 11, and the roller 31 is respectively interference fit with the corresponding guide rail 11 in the axial direction. The backrest frame 3 includes a backrest portion 32 and a buttocks guide portion 33, the rear end of the seat frame 2 is hinged to the backrest frame 3 and arranged above the buttocks guide portion 33, the first end of the connecting rod 5 is hinged to the front end of the seat frame 2, and the second end of the connecting rod 5 is hinged to the base 1 at a first hinge point a; the push rod 4 includes a guide rod 41 and a slider 42, the slider 42 is slidably arranged on the guide rod 41, one end of the push rod 4 is hinged to the base 1 at a second hinge point b, and the slider 42 is hinged to the buttocks guide portion 33 of the backrest frame 3.

[0019] like Figure 5 As shown, the slider 42 slides on the guide rod 41 in a direction away from the backrest portion 32, driving the backrest frame 3 to slide on the guide rail 11 in a direction toward the buttocks guide portion 33, so that the seat frame 2 drives the connecting rod 5 to swing away from the backrest portion 32 with the first hinge point a as a fulcrum, so that the angle between the seat frame 2 and the backrest portion 32 becomes larger;

[0020] like Figure 4 As shown, the slider 42 slides on the guide rod 41 toward the backrest portion 32, driving the backrest frame 3 to slide on the guide rail 11, so that the seat frame 2 drives the connecting rod 5 to swing in the direction close to the backrest portion 32 with the first hinge point a as the fulcrum, so that the angle between the seat frame 2 and the backrest portion 32 becomes smaller.

[0021] That is to say, the massage chair described in the embodiment of the present invention adopts a chair frame, a connecting rod structure and a guide rail, which not only satisfies the massage needs of customers from the neck to the buttocks, but also has a simple structure, and the posture can be adjusted during the massage. During the back massage, the user can stretch the body posture to make it more comfortable, and the backrest can be adjusted to a nearly horizontal state. With the ejection massage of the massage movement, the original stretching effect can be optimized, so that the user can get a better massage effect. Therefore, the physical discomfort caused by the fixed posture is avoided, and the stretchability of the body can be better guaranteed when taking a nap after the massage. On the other hand, when the massage chair is in an upright state, the massage movement can be well retracted in the guide rail under the buttocks guide part, and the user can not feel the foreign body sensation at all, which further enhances the user's favorability.

[0022] Further, in one example, Figure 3-7 As shown, the seat frame 2 is provided with a support plate 21 for the user to sit on; the backrest 32 is used to support the user's back, and the backrest 32 is also provided with a backrest support plate 321; it also includes a massage movement 8, and the backrest frame is provided with a rack guide rail, and the rack guide rail passes through the backrest and the buttocks guide part so that the massage movement can move from the backrest to the buttocks guide part to massage the human body.

[0023] Further, in one example, Figure 4 and Figure 5 As shown, the base 1 further includes a first vertical rod 12 and a second vertical rod 13, wherein the first vertical rod 12 and the second vertical rod 13 are spaced apart and the first vertical rod 12 is lower than the second vertical rod 13 in level; the guide rail 11 is arranged on the first vertical rod 12 and the second vertical rod 13. The guide rail can be an arc-shaped guide rail, which is arranged on the base with a lower front and a higher rear. The whole backrest frame can be moved forward and tilted backward, thereby achieving zero leaning against the wall and zero gravity, and improving the massage comfort.

[0024] like Figure 4 As shown, when the massage chair is in a sitting position, the first end of the connecting rod 5 is located on the side of the first vertical rod 12 close to the backrest 32, and the slider 42 is located on the side of the second vertical rod 13 close to the backrest 32; Figure 5As shown, when the massage chair is in a lying position, the first end of the connecting rod 5 is located on a side of the first vertical rod 12 away from the backrest 32 , and the sliding block 42 is located between the first vertical rod 12 and the second vertical rod 13 .

[0025] Furthermore, in one example, a calf assembly and a calf push rod (not shown in the figure) are further included, wherein the calf assembly is hinged to the front end of the seat frame, one end of the calf push rod is hinged to the base, and the other end is hinged to the calf assembly. Of course, other connecting rod mechanisms can also be used to lift and lower the calf assembly in a linked manner. This structure is a common structure, and the embodiments of the present invention will not be described in detail.

[0026] Furthermore, in one example, a control device is also included, which controls the push rod to push the backrest frame to change between a sitting state and a lying state, and controls the massage movement to reciprocate on the movement guide rail to massage the human body.

[0027] The installation relationship and working principle of the massage chair according to the embodiment of the present invention are described in detail below.

[0028] like Figure 1-7As shown, the massage chair provided by the embodiment of the present invention comprises a base 1, on which an arc-shaped guide rail 11 is fixed; a seat frame 2, on which a support plate 21 for a user to sit is arranged; a backrest frame 3, which comprises a backrest 32 and a buttocks guide 33, and the backrest 32 is used to support the back of the user; the main frame of the backrest frame 3 is a rigid square frame, and each of the left and right front and back has a support tube, and the support tube is pinned with a roller 31, which is used to roll on the arc-shaped guide rail 11 on the base 1; the seat frame 2 is mainly arranged in the buttocks section, and the seat frame 2 is provided with a support plate 21 for the user to sit; the ears 22 fixed at the rear end of the seat frame 2 are each provided with a screw hole, which is used to hinge the hole on the U-shaped tube 34 on the backrest frame 32, and perform single-point rotation movement; the front lower end of the seat frame 2 is each provided with a connecting rod ear seat 23, which is used to hinge the first end of the connecting rod 5, and the second end of the connecting rod 5 is hinged to the first hinge point a on the base 1. The main frame of the seat frame 2 is also rigid. The left and right sides of the backrest frame 3 are each provided with an L-shaped guide rail and front and rear fixed tubes. A rack is installed on the guide rail to guide the movement of the massage movement from the backrest to the buttocks guide part. The U-shaped tube 34 on the backrest frame 3 is fixed on the buttocks guide part 33, and a push rod ear seat 35 is provided to articulate the slider 42 of the push rod 4. Under the action of the push rod 4, the front sliding back movement can be performed. The shape of the L-shaped guide rail is basically L-shaped. The difference from the transmission L-shaped guide rail is that the L-shaped angle is larger. For example, the traditional guide rail is only about 120 degrees, and the angle of this solution can reach 143±10 degrees. The specific angle is designed according to the different heights of the massage movement. In order to make the movement hidden under the buttocks when the massage chair is in an upright state and not working, it does not affect the normal sitting feeling. When the massage movement moves in this position, the upper and lower massage wheels need to be below the plane of the seat frame, so as not to affect the sitting feeling.

[0029] During operation, the push rod 4 drives the backrest frame 3 to slide on the guide rail 11 toward the hip guide portion 33. Since the seat frame 2 is hinged to the U-shaped tube 34 on the backrest frame 3, the seat frame 2 is driven to slide forward together. Due to the existence of the connecting rod 5, the height of the seat frame 2 will be limited by the connecting rod 5 when it moves to a certain height, so that it can slide forward within a certain angle range, thereby realizing the opening of the backrest portion 32 and the seat frame 2.

[0030] In this way, the massage chair adopts a chair frame, a connecting rod structure and a guide rail, which not only satisfies the customer's massage from the neck to the buttocks, but also has a simple structure and can adjust the posture during massage. During the back massage, the body posture is stretched to make the user more comfortable, and the backrest can be adjusted to a nearly horizontal state. With the ejection massage of the massage movement, the original stretching effect can be optimized, so that the user can get a better massage effect. Therefore, the physical discomfort caused by the fixed posture is avoided, and the stretchability of the body can be better guaranteed during a nap after the massage. On the other hand, when the massage chair is in an upright state, the massage movement can be well retracted in the guide rail under the buttocks guide, and the user can not feel the foreign body at all, which further enhances the user's favorability.

[0031] 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.

[0032] 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.
