[0007] The convex rotating shaft below the seat frame is installed on the seat frame, and the convex rotating shaft can rotate on the seat frame. The convex rotating shaft cooperates with the deformation part on the seat frame, so that the seat frame forms a depression when the human body sits, so that the chair seat device can achieve a hip-wrapping effect; the buttocks sinking on the chair seat device are wrapped, so that the user's buttocks are gathered together to prevent deformation and looseness, which can both shape the body and take care of health; the convex rotating shaft can also serve as the main support of the deformation part, preventing the deformation part from producing exaggerated deformation and affecting comfort, and preventing the seat frame from being damaged due to excessive deformation.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] In the description of the present invention, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0028] The specific implementation of the utility model is as follows:

[0029] like Figure 2 , 3 As shown, the utility model provides a hip-wrapping chair seat device, comprising a seat frame 1 and a seat frame 2, the seat frame 2 is installed on the seat frame 1, a convex shaft 3 which is protruding downward and arranged horizontally is provided under the seat frame 2, and the convex shaft 3 is rotatably set on the seat frame 1; the seat frame 2 comprises a deformation part 4, the deformation part 4 is elastic, and the deformation part 4 and the convex shaft 3 are configured so that when a user sits on the chair seat device, the deformation part 4 is deformed, and at the same time the convex shaft 3 rotates relative to the seat frame 1, and the seat frame 2 is sunken to wrap the human buttocks.

[0030] The convex rotating shaft 3 below the seat frame 2 is installed on the seat frame 1, and the convex rotating shaft 3 can rotate on the seat frame 1. The convex rotating shaft 3 cooperates with the deformation part 4 on the seat frame 2, so that the seat frame 2 forms a depression when the human body sits, so that the chair seat device can achieve a hip-wrapping effect; the buttocks sinking on the chair seat device are wrapped, so that the user's buttocks are gathered together to prevent deformation and looseness, which can both shape the body and take care of health; the convex rotating shaft 3 can also serve as the main support of the deformation part 4, preventing the deformation part 4 from producing exaggerated deformation and affecting comfort, and preventing the seat frame 2 from being damaged due to excessive deformation.

[0031] Specifically, if Figure 1 , 2 As shown, the chair seat device also includes a cushion 5, which is arranged on the seat frame 2 and covers the upper surface of the seat frame 2. The cushion 5 will produce corresponding deformation as the seat frame 2 deforms. The upper surface of the cushion 5 forms a support surface for supporting the buttocks of the human body. This solution enables the support surface to fit the buttocks of the human body, and at the same time the chair seat device wraps the buttocks of the human body.

[0032] like Figure 3-5As shown, the seat frame 2 includes two deformation parts 4, which are symmetrically distributed on the seat frame 2, and the convex rotation shaft 3 is located below the deformation part 4. The convex rotation shaft 3 is provided below the two deformation parts 4, and the convex rotation shaft 3 is arranged along the front-to-back direction, that is, the axis of the convex rotation shaft 3 extends along the front-to-back direction; Figure 5 , 6 As shown, the convex rotating shaft 3 has a curved surface located at the bottom, and a rotation groove 6 is opened on the seat frame 1 corresponding to the curved surface of the convex rotating shaft 3, and the convex rotating shaft 3 is rotatably set in the rotation groove 6. Specifically, a plurality of vertically arranged support plates 7 are provided on the seat frame 1, and the rotation groove 6 is opened on the support plates 7; the support plates 7 are symmetrically distributed on both sides of the seat frame 1 in the same number, and the support plates 7 located on one side of the seat frame 1 are arranged at intervals along the front and rear directions. In this embodiment, there are six support plates 7 on each side, and the rotation grooves 6 on each support plate 7 located on one side of the seat frame 1 are aligned. After the convex rotating shaft 3 is placed in the rotation grooves 6 of these support plates 7, it can rotate stably. The reason why the two deformation parts 4 are arranged left and right instead of front and back is that when sitting, the most obvious deformation is the left and right expansion of the buttocks. The deformation parts 4 are symmetrically distributed on the left and right sides, and can mainly provide left and right sides to wrap the buttocks when they are deformed inward, thereby tightening the buttocks and preventing the buttocks from expanding outward in the left and right directions. The support piece 7 is selected instead of the overall seat in order to save costs and reduce the overall weight of the seat frame 1. With the action of multiple support pieces 7, the seat frame 2 can be stably supported, and the convex rotating shaft 3 can also rotate stably.

[0033] Furthermore, if Figure 3 , 4 As shown, the seat frame 2 is provided with a plurality of hollows, which are arranged around the deformation portion 4, and the hollows provide favorable conditions for the deformation of the deformation portion 4; specifically, the hollows are divided into U-shaped hollows 8, transverse hollows 9 and longitudinal hollows 10, and there are a plurality of U-shaped hollows 8, which are arranged along the contour of the deformation portion 4, and a plurality of U-shaped hollows 8 are arranged around each deformation portion 4, and the plurality of U-shaped hollows 8 are arranged at intervals along the left and right directions. In the present embodiment, three U-shaped hollows 8 are arranged around a single deformation portion 4 from the outside to the inside, and the U-shaped hollows 8 closer to the middle of the seat frame 2 are larger in size, and the U-shaped hollows 8 on the inner side surround the U-shaped hollows 8 on the outer side; and then In one step, the outer side of the deformation part 4 is connected to the main body of the seat frame 2, and the connection is the deformation position. The U-shaped hollow 8 is located around the contour of the deformation part 4, so that the other three sides of the deformation part 4 are separated from the main body of the seat frame 2, and the deformation part 4 can be flexibly deformed. When the human body sits, the inner side of the deformation part 4 is displaced downward relative to the outer side, and the whole can bend and deform downward, thereby producing an inward-sinking effect; there is more than one U-shaped hollow 8 around the deformation part 4, and each U-shaped hollow 8 is arranged at intervals, so that the deformable area of ​​the seat frame 2 radiates outward from the deformation part 4, thereby increasing the deformation ability, and at the same time further wrapping the buttocks from the front and back directions.

[0034] The transverse hollowing 9 is arranged along the left-right direction, and the longitudinal hollowing 10 is arranged along the front-back direction. In the present embodiment, there is only one longitudinal hollowing 10, which is located on the center line of the seat frame 2; the transverse hollowing 9 includes a partitioning hollowing 91, and the partitioning hollowing 91 is opened on the deformation part 4, and the two deformation parts 4 are partitioned by the partitioning hollowing 91. In the present embodiment, in addition to the partitioning hollowing 91, there are three transverse hollowings 9, and the lengths of the three transverse hollowings 9 are all different. Two transverse hollowings 9 are opened at the front of the seat frame 2, and the other transverse hollowing 9 is opened at the rear of the seat frame 2; the transverse hollowing 9 can further increase the ability of the seat frame 2 to deform in the front-back direction, and the longitudinal hollowing 10 further increases the ability to deform in the left-right direction; the partitioning hollowing 91 partitions the single deformation part 4, and also allows the deformation part 4 itself to produce a front-to-back twisting deformation, which is more flexible and increases the wrapping ability of the seat device in the front-to-back direction.

[0035] Furthermore, if Figure 4 , 5 As shown, a plurality of U-shaped connecting pieces 11 are provided at the hollowed-out parts, and the connecting pieces 11 are all protruding and bent downward; the connecting pieces 11 increase the overall strength of the deformable part 4 while maintaining the deformable ability of the deformable part 4; due to the deformable ability of the seat device, when a human body sits, the supporting surface will also be concave and deformed downward, the area of ​​the entire supporting surface is increasing, and the hollowing is expanding. At this time, the connecting pieces 11 are more needed to improve the strength of the seat frame 2.

[0036] In addition, the front and rear parts of the seat frame 2 and the seat frame 1 are connected by screws.
