Description

Technical Field

[0001] This utility model relates to the field of massage chair technology, specifically to a massage chair frame. Background Technology

[0002] With continuous economic development and the accelerating pace of life, people are paying more and more attention to their physical and mental health. Massage chairs are widely popular because they can improve blood circulation, alleviate back pain and prevent illness, improve sleep quality, and relieve overall fatigue. Massage chairs utilize mechanical rolling and squeezing forces for massage. The massage chair frame, as a crucial component, supports the chair and, through the sliding cooperation between the electric push rod and the frame components, allows for switching between reclining and upright positions. Currently, most massage chair frames on the market use multi-link mechanisms, which are complex, costly, and, due to structural design flaws, have gaps at the joints during position changes, resulting in mediocre comfort and a poor user experience. Therefore, designing a new type of massage chair frame is particularly necessary. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a massage chair frame that is simple in structure, reasonable in design, reduces production costs, provides high comfort, improves user experience, is highly practical, and is easy to promote and use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a massage chair frame, comprising a backrest frame assembly, a seat cushion frame assembly, and a seat frame assembly. The backrest frame assembly and the seat cushion frame assembly are connected on both sides by internal hinge bolts, copper sleeves, and nuts. A first electric push rod is connected between the backrest frame assembly and the seat cushion frame assembly. The backrest frame assembly is mounted on the seat frame assembly by external hinge bolts. A second electric push rod is connected between the seat frame assembly and the seat cushion frame assembly. The backrest frame assembly and the seat cushion frame assembly are respectively provided with an upper rail and a lower rail, and a pressure strip is provided at the connection between the lower rail and the upper rail.

[0005] Preferably, the first electric push rod is installed in the middle of the push rod frame at the bottom of the seat cushion frame assembly, and the extended end of the first electric push rod is connected to the middle of the backrest frame on the back of the backrest frame assembly.

[0006] Preferably, the second electric push rod is vertically fixed to the middle of the front end of the seat frame assembly, and the extended end of the second electric push rod is connected to the middle of the front end of the seat cushion frame assembly.

[0007] Preferably, the pressure strip is fixed on the lower track, and the end of the pressure strip extends into the upper track, so that the gap can be adjusted and repaired through the pressure strip.

[0008] The beneficial effects of this utility model are: this device simplifies the overall structure of the massage chair frame, provides high comfort, improves the user experience, has high reliability, reduces the production cost of the massage chair, and has broad application prospects.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Reference Figure 1-5 The specific embodiment adopts the following technical solution: A massage chair frame includes a backrest frame assembly 1, a seat cushion frame assembly 2, and a seat frame assembly 3. The two sides of the backrest frame assembly 1 and the seat cushion frame assembly 2 are connected by an inner hinge bolt 4, a copper sleeve 5, and a nut 6. A first electric push rod 7 is connected between the backrest frame assembly 1 and the seat cushion frame assembly 2. The first electric push rod 7 is installed in the middle of the push rod frame 12 at the bottom of the seat cushion frame assembly 2. The extended end of the first electric push rod 7 is connected to the middle of the backrest frame 13 on the back of the backrest frame assembly 1. The backrest frame assembly 1 is installed on the seat frame assembly 3 by an outer hinge bolt 14. A second electric push rod 8 is connected between the seat frame assembly 3 and the seat cushion frame assembly 2. The second electric push rod 8 is vertically fixed in the middle of the front end of the seat frame assembly 3. The extended end of the second electric push rod 8 is connected to the middle of the front end of the seat cushion frame assembly 2.

[0017] This specific embodiment is equipped with two push rod structures: a first electric push rod 7 and a second electric push rod 8. The angle of the chair frame is adjusted by using the first electric push rod 7 and the second electric push rod 8. By controlling the length of the first electric push rod 7, the angle between the backrest frame assembly 1 and the seat cushion frame assembly 2 can be adjusted. By controlling the length of the second electric push rod 8, the angle between the upper part of the whole assembly composed of the backrest frame assembly 1 and the seat cushion frame assembly 2 and the lower part of the seat frame assembly 3 can be adjusted. The two push rod structures combined realize multi-directional angle adjustment of the entire chair frame.

[0018] In this specific embodiment, an upper rail 9 and a lower rail 10 are respectively provided on the backrest frame assembly 1 and the seat cushion frame assembly 2. A pressure strip 11 is provided at the connection between the lower rail 10 and the upper rail 9. When the chair frame is in the upright state, the upper rail 9 of the backrest frame assembly 1 and the lower rail 10 of the seat cushion frame assembly 2 are in a flat joint state. In this state, the pressure strip 11 is fixed on the lower rail 10, and the end of the pressure strip 11 extends into the upper rail 9. When the chair frame is in the reclined state, the upper rail 9 of the backrest frame assembly 1 and the lower rail 10 of the seat cushion frame assembly 2 open up, creating a gap. At this time, the end of the pressure strip 11 extends into the upper rail 9 to fill the gap.

[0019] This specific embodiment improves the backrest frame track and seat cushion frame track structure, making the user's massage experience more comfortable. At the same time, by controlling the length adjustment angle of the double push rods, the massage combination methods are more diverse, improving the user experience and reducing the production cost of the massage chair, which has broad market application prospects.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
