Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Embodiments of the present utility model provide a massage chair 100 (shown in fig. 1) that can facilitate adjustment of the angle between the back frame 10 and the seat frame 20. The massage chair 100 includes: a back frame 10 (shown in fig. 2), two sides of which are provided with back frame sliding blocks 11, wherein the back frame 10 and the back frame sliding blocks 11 can rotate relatively; a seat frame 20 (shown in fig. 3) rotatably connected with the back frame 10, and seat frame sliding blocks 21 are arranged at two sides of the seat frame 20; the underframe 30 (as shown in fig. 4) is provided with a pair of back slide rails 31 and a pair of seat slide rails 32, the back-frame slider 11 is mounted on the back slide rails 31, and the seat frame slider 21 is mounted on the seat slide rails 32; the seat frame slider 21 is in sliding fit with the seat slide rail 32, and the back frame 10 changes the angle with the seat frame 20 in such a manner that the back frame slider 11 slides in the back slide rail 31 and the back frame 10 rotates.

When the seat frame slider 21 moves forward in the seat slide rail 32, the seat frame 20 moves forward and drives the back frame 10 rotatably connected thereto to tilt rearward. At the same time, to accommodate the movement of the back frame 10, the back frame slider 11 slides down in the back slide rail 31. The shapes of the back frame slider 11 and the seat frame slider 21 are not particularly limited, and may be circular, polygonal, or the like in other embodiments. The shapes of the back rail 31 and the seat rail 32 may be selected according to practical needs, for example, a straight rail or a rail with an arc in other embodiments.

Referring to fig. 1-3, in this embodiment, the rotational connection between the back frame 10 and the seat frame 20 may be achieved by using pins 40 to connect together the transfer sheet metal 41 on the back frame 10 and the transfer sheet metal 41 on the seat frame 20.

In the present embodiment, in order to facilitate the processing of the slide rail and the slider and to improve the stability of the movement of the slider in the slide rail, the seat rail 21 is rectangular, the seat rail 32 is a straight rail, and the seat rail 21 slides in the seat rail 32 in such a manner that two vertically opposite planes are in contact with the seat rail 32. The shape and structure of the back frame slider 11 and the back slide rail 31 are similar to those of the seat frame slider 21 and the seat slide rail 32.

In the present embodiment, in order to achieve the relative rotation between the back frame 10 and the back frame slider 11, the back frame 10 and the back frame slider 11 are connected by a fastener 112 (for example, a pin). Specifically, as shown in fig. 7, the back frame slider 11 is provided with an opening 111, one end of a fastener 112 is rotatably connected to the opening 111, and the other end of the fastener 112 is connected to the back frame 10. The inner surface of the opening 111 is smooth and the fastener 112 is free to rotate within the opening 111. When the back frame slider 11 slides in the back slide rail 31, the back frame slider 11 only translates, but does not rotate, compared to the back slide rail 31. At this time, the relative rotation between the back frame 10 and the back frame slider 11 is achieved by the fastener 112 connected to the back frame 10 rotating in the opening 111 of the back frame slider 11. In other words, if the back rail 31 is used as a reference, the fastener 112 and the back frame 10 connected thereto are rotated, but the back frame slider 11 is not rotated. The above-described connection structure between the back frame 10 and the back frame slider 11 is only an alternative embodiment, and those skilled in the art may select other connection structures to achieve the relative rotation between the back frame 10 and the back frame slider 11.

In this embodiment, the included angle between the seat frame 20 and the back frame 10 is in the range of 115 ° to 145 °, which can meet the requirements of stretching the posture of the user, and facilitate the fixed installation of the back frame, the seat frame and the bottom frame. Fig. 5 shows a state in which the angle between the seat frame 20 and the back frame 10 is small, and fig. 6 shows a state in which the angle between the seat frame 20 and the back frame 10 is large. In other embodiments, the variable range of the included angle between the seat frame 20 and the back frame 10 may be smaller, for example, 120 ° to 140 °, and the smaller variable range of the included angle is beneficial to reduce the stroke length of the slider in the sliding rail to some extent, thereby reducing the failure rate. The variable range of the included angle between the seat frame 20 and the back frame 10 can be larger (110 degrees to 150 degrees), so as to meet the requirements of partial users on the lying angle.

In this embodiment, in order to achieve simultaneous massage of the back and buttocks of the user, the massage chair 100 is provided with two massage cores, specifically, as shown in fig. 1, the back frame 10 is provided with a rack rail 13, and the back massage core 12 is connected with the rack rail 13; the seat frame 20 is provided with a seat surface 22, and the seat massage movement 23 is fixed in a mounting groove 221 of the seat surface 22. As further shown in fig. 8, a support spring 24 is further provided between the seat massage movement 23 and the seat surface 22. In the present embodiment, the seat massage machine 23 is fixed to the mounting groove 221 of the seat 22, so that the mounting structure of the seat massage machine 23 can be simplified, and the problem of excessive abnormal noise due to the provision of a complicated transmission mechanism (for example, using a guide rail) on the seat frame 20 can be avoided. The seat massage machine core 23 can adaptively adjust the massage force according to the weight of the user by arranging the supporting springs 24, so that the massage force and the sitting comfort are both considered.

Referring to fig. 3, 8 and 9, a seat 22 is fixed to the seat frame 20 of the massage chair 100 by a plurality of seat fixing screws 50. The seat surface 22 is provided with a mounting groove 221 for mounting and fixing the seat massage movement 23. The bottom of the mounting groove 221 is provided with a plurality of positioning posts 241 and supporting springs 24 sleeved on the positioning posts 241. The seat massage movement 23 is placed in the mounting groove 221 with the support spring 24 aligned with the positioning hole 238 at the bottom of the seat massage movement 23, and finally the pressing plate 237 is mounted. The seat massage movement 23 is restrained and fixed at a specific position on the seat surface 22 by the mounting groove 221, the supporting spring 24 and the pressing plate 237.

In the present embodiment, in order to allow the seat surface 22 to provide a certain supporting function for the thighs of the user, as shown in fig. 8, a convex region 25 is provided on the side of the seat surface 22 away from the back frame 10. And in order to allow the seat massage movement 23 to massage the rear side of the user's thigh, the mounting groove 221 is provided to extend to the convex area 25 in the present embodiment.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
