[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 5 One embodiment of this utility model provides a saddle chair, comprising: Seat 10; Backrest assembly 20, which is rotatably mounted on seat 10 via at least one rotating structure 21; The rotating structure includes a first rotating member 22, a second rotating member 23 and an elastic member 24. The first rotating member 22 is disposed on the backrest assembly 20 and rotates in cooperation with the second rotating member 23. A first angle limiting structure 25 is provided between the second rotating member 23 and the first rotating member 22. The first angle limiting structure 25 restricts the rotation range of the first rotating member 22 relative to the second rotating member 23, so as to limit the backrest assembly 20 from rotating between the folded position toward the seat 10 and the unfolded position away from the backrest assembly 20. A second angle limiting structure 26 is provided between the first rotating member 22 and the seat 10. The second angle limiting structure 26 restricts the rotation range of the second rotating member 23 relative to the seat 10, so as to limit the backrest assembly 20 from rotating between the unfolded position and the buffer position. When the seat 10 rotates from the unfolded position to the buffer position, the elastic member 24 undergoes elastic deformation.

[0021] The working principle of a saddle chair according to one embodiment of the present invention is explained below: When the saddle chair needs to be folded, the backrest assembly 20 rotates toward the seat 10 to achieve mutual folding of the backrest assembly 20 and the seat 10, thereby reducing the volume of the backrest assembly 20 and the seat 10 for convenient packaging, transportation, and storage. At this time, the first rotating member 22 rotates relative to the second rotating member 23 to one of the extreme positions limited by the first angle limiting structure 25.

[0022] When the saddle chair is needed, the backrest assembly 20 rotates away from the seat 10 so that the backrest assembly 20 is behind the seat 10. At this time, the first rotating member 22 rotates relative to the second rotating member 23 to another extreme position limited by the first angle limiting structure 25. After the backrest assembly 20 is unfolded, the user can sit on the seat 10, and the backrest assembly 20 can support the user's back.

[0023] When a user sits on the seat 10, their back may lean backward. At this time, the backrest assembly 20 can rotate backward away from the seat 10, i.e., rotate towards the buffer position. During this rotation, the first rotating member 22 remains at another extreme position limited by the first angle limiting structure 25 relative to the second rotating member 23. The backrest assembly 20, through the first rotating member 22, drives the second rotating member 23 to rotate relative to the seat 10. The second rotating member 23 will compress the elastic member 24, and the elastic force of the elastic member 24 will provide a buffering force to the second rotating member 23. Thus, the rotation of the backrest assembly 20 towards the buffer position provides a cushioning effect for the user. In this embodiment, the angular interval between the unfolded position and the buffer position is 20°. Of course, a larger or smaller interval angle can be designed according to actual needs.

[0024] The specific structure of the first rotating member 22 and the second rotating member 23 can be designed according to actual needs. For example, in some optional embodiments, the first rotating member 22 is a rotating sleeve and the second rotating member 23 is a rotating shaft. At least part of the rotating shaft is driven through the rotating sleeve, so that the first rotating member 22 and the second rotating member 23 are stably assembled.

[0025] Please see Figure 5 and Figure 6 The specific structure of the first angle limiting structure 25 can be designed according to actual needs. For example, in some optional embodiments, the first angle limiting structure 25 includes a first limiting part 251 disposed on the first rotating member 22 and a first limiting groove 252 disposed on the second rotating member 23. When the backrest assembly 20 rotates between the folded position and the unfolded position, the first limiting part 251 slides in cooperation with the first limiting groove 252. When the backrest assembly 20 is in the folded position, the first limiting part 251 abuts against the first end of the first limiting groove 252, that is, the first rotation... When the first rotating member 22 rotates relative to the second rotating member 23 to one of the extreme positions limited by the first angle limiting structure 25, and the backrest assembly 20 is in the unfolded position, the first limiting part 251 abuts against the second end of the first limiting groove 252, that is, the first rotating member 22 rotates relative to the second rotating member 23 to the other extreme position limited by the first angle limiting structure 25. When rotating between the unfolded position and the buffer position, the first limiting part 251 remains abutting against the second end of the first limiting groove 252, thereby enabling the first rotating member 22 to drive the second rotating member 23 to rotate. Of course, the first limiting part 251 can also be provided on the second rotating member 23, and the first limiting groove 252 can also be provided on the first rotating member 22, and this example is not limited.

[0026] The specific structure of the second angle limiting structure 26 can be designed according to actual needs. For example, in some optional embodiments, the second angle limiting structure 26 includes a second limiting part 261 disposed on the second rotating member 23 and a second limiting groove 262 disposed on the second rotating member 23. When the backrest assembly 20 rotates between the buffer position and the unfolded position, the second limiting part 261 slides along the second limiting groove 262. When the backrest assembly 20 is in the folded position, the second limiting part 261 abuts against the first end of the second limiting groove 262. When the backrest assembly 20 is in the buffer position, the second limiting part 261 abuts against the second end of the second limiting groove 262. Of course, the second limiting part 261 can also be disposed on the housing, and the second limiting groove 262 can also be disposed on the second rotating member 23, without limitation.

[0027] In some alternative embodiments, the backrest assembly 20 is rotatably engaged with the seat 10 via two rotating structures 21, which are located on opposite sides of the seat 10. These two rotating structures 21 improve the stability of the backrest assembly 20's rotation. Alternatively, the backrest assembly 20 may also have only one rotating structure 21 and another pivot structure.

[0028] Please see Figure 7 In some optional embodiments, the seat 10 is provided with at least one positioning pin 12, and the second rotating member 23 is provided with a positioning recess 231 and a positioning groove 232. When the seat 10 is in the folded position, the positioning pin 12 is positioned and engaged with the positioning recess 231, so that the backrest assembly 20 can be held in the unfolded position. When the seat 10 is between the unfolded position and the buffer position, the positioning pin 12 is positioned and engaged with the positioning groove 232, so that the seat 10 is held between the unfolded position and the buffer position. When the user is not sitting on the seat 10, the elastic force of the elastic member 24 is used to keep the backrest assembly 20 in the unfolded position.

[0029] The principle and structure of the positioning marble 12 are well known to those skilled in the art, and will not be described in detail here.

[0030] In some alternative embodiments, a main shaft 11 is provided on the seat 10, and shaft holes 233 are provided in the first rotating member 22 and the second rotating member 23. The main shaft 11 passes through the shaft holes 233 of the first rotating member 22 and the second transmission member of the two rotating structures 21, which is beneficial to improve the coaxiality of the two rotating shaft structures and improve the rotational stability of the first rotating member 22 and the second rotating member 23.

[0031] The specific structure of the elastic element 24 can be designed according to actual needs. For example, in some optional embodiments, the elastic element 24 is a torsion spring, which is sleeved on the main shaft 11. One end of the torsion spring is connected to the second rotating element 23, and the other end is connected to the seat 10. When the second rotating element 23 rotates relative to the housing, the torsion spring will generate elastic deformation to provide a buffering force. A rubber sleeve is also provided on the main shaft 11, and the torsion spring is sleeved on the rubber sleeve.

[0032] In some alternative embodiments, the backrest assembly 20 is provided with two rotating arms 27, which are disposed on both sides of the seat 10. The second rotating member 23 of the rotating structure 21 is correspondingly arranged on the rotating arms 27, and the two rotating arms 27 facilitate the position arrangement of the second rotating member 23.

[0033] In some alternative embodiments, at least one pressure cover 13 is detachably provided on the seat 10, forming a rotation space between the pressure cover 13 and the seat 10. The second rotating member 23 is rotatably disposed within the rotation space, and the pressure cover 13 enables the detachable installation of the second rotating member 23, facilitating its installation. In this embodiment, the second limiting groove 262 is provided on the pressure cover 13.

[0034] In some alternative embodiments, the seat 10 is provided with an elastic cushion 14 to improve the comfort of the user sitting on the seat 10.

[0035] Please see Figure 8 The bottom of the seat 10 is usually provided with a base frame 30 to facilitate the placement of the seat 10. The bottom of the base frame 30 is equipped with casters to facilitate the movement of the base frame 30.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
