[0039] In the description of the present utility model, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0040] The embodiment of the present utility model provides a seat support structure 1000, which is applied to a seat 2000. The specific structure and function of the seat support structure 1000 provided by the embodiment of the present utility model will be further described below in combination with the text and the drawings.

[0041] Refer to Figures 1 to 3, the seat support structure 1000 provided by the first aspect embodiment of the present utility model includes: a bracket 100, a seat cushion 200, and a backrest support assembly 300. Connecting arms 110 extending upward and outward are provided on the left and right sides of the bracket 100. The connecting arms 110 are made of strong plastic or metal to ensure sufficient support strength. The seat cushion 200 is disposed between the two connecting arms 110 and is firmly connected to the connecting arms 110 by bolts or other fasteners. The seat cushion 200 adopts an ergonomic design to provide a comfortable sitting feeling. The backrest support assembly 300 includes a connecting frame 310 and a backrest 320. The two sides of the connecting frame 310 are respectively connected to the two connecting arms 110 at a first connection point 120. The line connecting the two first connection points 120 is a first axis. The first connection point 120 is connected through a rotating structure such as a bearing or a hinge, so that the connecting frame 310 and the backrest 320 can rotate freely around the first axis. The first axis is located above the rear part of the seat cushion 200, and the specific height can be designed according to the ergonomic principle to ensure matching with the rotation axis when the user reclines.

[0042] The seat support structure 1000 provided by the first aspect embodiment of the present utility model improves the problem that the user's back and the backrest 320 are not synchronized during the reclining process of the traditional seat 2000 through innovative design. Specifically, the seat support structure 1000 sets the first connection point 120 of the connecting frame 310 and the backrest 320 above the rear part of the seat cushion 200, and enables the connecting frame 310 and the backrest 320 to rotate around the first axis. When the user reclines while sitting on the seat cushion 200, the rotation axis of the user is basically at the same height as the first axis, that is, the left and right femoral heads of the user and the two first connection points 120 of the first axis are basically in the same position, ensuring that the rotation of the human back and the backrest 320 is coaxial and of the same radius. It should be noted that this consistency is not only reflected in height, but also in that the distance from the axis point to the contact between the sponge and the human back and the distance from the femoral head of the human body to the skin are basically the same. By accurately solving these two perpendicular distances of height and thickness, the rotation axis point can be accurately positioned, thereby realizing coaxial and same-radius rotation, so as to ensure that the user's back can remain relatively stationary with the backrest 320 during the reclining process, effectively avoiding common discomforts such as "rubbing the back" or "hitting the back of the head" when the traditional seat 2000 reclines, greatly improving the user experience, enabling the user to enjoy more comfortable and natural back support during the reclining process, and enhancing the user experience.

[0043] It can be understood that the backrest 320 is connected to the connecting frame 310 and rotates around the first axis together with the connecting frame 310. The backrest 320 adopts a shape that conforms to the curve of the human back to provide the best back support. When the user sits on the seat cushion 200 and leans backward, since the height of the first axis is similar to the rotation axis of the user, the backrest 320 can remain relatively stationary with respect to the user's back, thus avoiding the discomfort that may occur during the tilting process of the traditional seat 2000.

[0044] It can be understood that the backrest 320 and the connecting frame 310 can be an integrally formed structure or a split structure; when the backrest 320 and the connecting frame 310 are in a split structure, the seat support structure 1000 in this embodiment can further include a backrest 320 adjustment mechanism for adjusting the height of the backrest 320 relative to the seat cushion 200 to meet the personalized needs of different users. The adjustment mechanism can be arranged between the connecting frame 310 and the backrest 320, and specifically, the height adjustment can be achieved by engaging the teeth into different stepped grooves.

[0045] It should be noted that when applying the embodiment of the present utility model to the seat 2000, the bracket 100 directly fixes the seat cushion 200 and the backrest 320, thereby realizing the chassis-free design of the seat 2000. This not only simplifies the structure of the seat 2000 and reduces the production cost, but also enables the seat 2000 to have a more concise and modern appearance. In addition, the rear sides of the seat cushion 200 and the bracket 100 adopt a suspended design. This provides sufficient space for the rotation of the backrest 320. When the user needs to adjust the angle of the backrest 320, the lower end of the connecting frame 310 can easily rotate and enter the suspended part at the rear of the seat cushion 200 and the bracket 100. This not only makes the rotation of the backrest 320 smoother, but also greatly saves the space occupied by the seat 2000 during use.

[0046] Refer to Figures 1 to 3 , according to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, the seat cushion 200 is rotatably connected to two connecting arms 110, and the connection points between the seat cushion 200 and the two connecting arms 110 are defined as the second connection points 130. The second connection points 130 can also be connected through bearings, hinges or other rotating devices to ensure that the seat cushion 200 can rotate freely. The line connecting the two second connection points 130 constitutes the second axis, and this second axis is located below the front side of the first axis. Such a design enables the seat cushion 200 to rotate around the second axis when subjected to the user's force, thereby providing a more flexible sitting posture adjustment space for the user. When the user needs to adjust the sitting posture or perform certain specific actions, the rotating design of the seat cushion 200 can reduce the friction and resistance between the body and the seat cushion 200, improving the comfort and adaptability of the seat 2000.

[0047] It can be understood that since the second axis is located below the front side of the first axis, the rotation of the seat cushion 200 will not interfere with the normal operation of the backrest support assembly 300. When the user reclines backward, the backrest support assembly 300 can still rotate around the first axis to remain relatively stationary with the user's back, providing stable back support. The rotation of the seat cushion 200 provides additional degrees of freedom for the user, enabling the seat 2000 to adapt to more different usage scenarios and requirements.

[0048] Referring to Figures 1 to 3 , according to the seat support structure 1000 provided by the first aspect embodiment of the present invention, the upper part of the connecting arm 110 is provided with a connecting portion 111 extending backward, and both sides of the connecting frame 310 are provided with rotating arms 311. The rotating arms 311 are connected to the connecting frame 310 through a first rotating shaft 150. Specifically, the upper part of the connecting arm 110 is provided with a strip-shaped connecting portion 111 extending backward for a firm connection with the connecting frame 310. Both sides of the connecting frame 310 are provided with rotating arms 311, which are important components of the connecting frame 310 and are used to realize the rotational connection between the connecting frame 310 and the connecting arm 110. The rotating arms 311 are connected to the connecting frame 310 through a first rotating shaft 150. The first rotating shaft 150 can be a bolt, a pin shaft, or other components capable of realizing rotational connection. Such a design enables the connecting frame 310 to rotate relative to the connecting arm 110, thereby realizing the reclining function of the backrest 320.

[0049] It can be understood that the axis of the first rotating shaft 150 coincides with the first axis. When the user sits on the seat cushion 200 and reclines backward, the rotating arms 311 of the connecting frame 310 will rotate around the first rotating shaft 150, driving the backrest 320 to recline together. Since the first rotating shaft 150 is located between the connecting portion 111 of the connecting arm 110 and the rotating arms 311, the reclining process of the backrest 320 is smooth and does not produce a sudden or stuck feeling. At the same time, this connection method also ensures that the backrest 320 can remain relatively stationary with the user's back during the reclining process, providing comfortable back support.

[0050] Referring to Figures 1 to 3 , according to the seat support structure 1000 provided by the first aspect embodiment of the present invention, two support arms 140 are provided on the front side of the bracket 100. The two support arms 140 extend in the direction towards the seat cushion 200, forming an effective support for the front part of the seat cushion 200. When the seat cushion 200 rotates around the second axis, the front part of the seat cushion 200 will abut against the support arms 140, thereby restricting the further rotation of the seat cushion 200 and providing stable support.

[0051] It can be understood that the design of the two front support arms 140 enhances the stability of the seat cushion 200 during rotation, preventing the user from losing balance or falling due to excessive rotation of the seat cushion 200. Secondly, the abutting effect of the support arm 140 provides a clear rotation range for the seat cushion 200, enabling the user to more easily control and adjust the position of the seat cushion 200. Finally, the presence of the support arm 140 also increases the overall structural strength of the seat 2000, improving the durability and safety of the seat 2000.

[0052] In practical applications, the support arm 140 can be adjusted and optimized according to the user's needs and the specific design of the seat 2000. For example, the length, shape, and angle of the support arm 140 can be matched according to the size and shape of the seat cushion 200 to ensure the best support effect and user experience.

[0053] It can be understood that after the upper end of the support arm 140 extends to the lower part of the front of the seat cushion 200, it extends horizontally backward and is connected to the middle part of the connecting arm 110, thereby providing a certain support for the connecting arm 110 and improving the overall stability of the bracket 100 structure.

[0054] Refer to Figure 1 and Figure 2 According to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, the seat cushion 200 includes a soft pad and a support shell 210. The support shell 210 is provided on the lower side of the soft pad. The support shell 210 provides additional support and stability for the soft pad, and at the same time serves as a connection bridge between the seat cushion 200 and the connecting arm 110. The design of the support shell 210 can be matched according to the shape and size of the seat cushion 200 to ensure the best support effect and connection stability. A second rotating shaft 160 is provided between the two connecting arms 110. The axis of the second rotating shaft 160 coincides with the second axis. A second rotating shaft 160 is provided between the two connecting arms 110, and the axis of this second rotating shaft 160 coincides with the second axis, so that the seat cushion 200 can rotate around the second axis (i.e., the axis of the second rotating shaft 160), thereby realizing the flexible adjustment of the seat cushion 200.

[0055] When the user sits down, the seat cushion 200 will rotate around the second rotating shaft 160, so that the seat cushion 200 can fit more closely to the user's buttocks. In addition, since the axis of the second rotating shaft 160 coincides with the second axis, the rotation process of the seat cushion 200 is smooth and does not produce a sudden or stuck feeling. At the same time, the presence of the support shell 210 also ensures the stability and safety of the seat cushion 200 during rotation.

[0056] Refer to Figures 1 to 3, according to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, a buffer member 400 is provided between the support arm 140 and the bottom of the seat cushion 200. The buffer member 400 can be made of a rubber pad, a spring, an air cushion or other materials with elasticity and buffering ability. One end of the buffer member 400 abuts against the bottom of the seat cushion 200, and the other end abuts against the upper end surface of the support arm 140, so that when the seat cushion 200 rotates around the second axis and abuts against the support arm 140, the buffer member 400 can effectively absorb and disperse the generated impact force, thereby protecting the seat cushion 200 and the support arm 140 from damage and reducing noise and vibration.

[0057] It can be understood that the buffer member 400 can also reduce the impact force between the seat cushion 200 and the user's buttocks during the process of the user sitting down, improving the comfort of the seat 2000; in addition, the buffer member 400 can also effectively prevent wear and deformation caused by direct collision between the seat cushion 200 and the support arm 140, maintaining the stability and beauty of the seat 2000.

[0058] In practical applications, the material, shape and thickness of the buffer member 400 can be adjusted and optimized according to the specific design of the seat 2000 and the needs of users. For example, for a seat 2000 that requires higher comfort, a softer and more elastic buffer member 400 can be selected; while for a seat 2000 that requires higher stability, a harder and more wear-resistant buffer member 400 can be selected.

[0059] Refer to Figures 1 to 3 , according to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, the buffer member 400 is a spring. The spring has good elasticity and resilience, and can effectively absorb and disperse the impact force generated when the seat cushion 200 rotates. An installation groove is provided at the bottom of the seat cushion 200, and a connecting column is provided in the middle of the installation groove. The connecting column serves as the connection point between the spring and the seat cushion 200, ensuring the stable installation and effective operation of the spring. At the same time, the upper end surface of the support arm 140 is concave to form a receiving groove, and the shape of the receiving groove matches the shape of one end of the spring, so that the spring can be firmly abutted against the bottom wall of the receiving groove. When the seat cushion 200 rotates and abuts against the support arm 140, the spring will be compressed, thereby absorbing and dispersing the generated impact force. Since the other end of the spring is sleeved on the connecting column, this ensures that the spring can maintain a stable position and direction when being compressed and will not shift or deform due to the force. Such a design not only improves the comfort and stability of the seat 2000, but also increases the service life of the seat 2000. The spring as the buffer member 400 can effectively prevent wear and deformation caused by direct collision between the seat cushion 200 and the support arm 140, maintaining the beauty and practicality of the seat 2000.

[0060] In practical applications, the material, specifications, and installation method of the spring can be adjusted and optimized according to the specific design of the seat 2000 and the needs of users. For example, for the seat 2000 that requires higher elasticity, springs that are thinner and longer can be selected; while for the seat 2000 that requires higher stability, springs that are thicker and shorter can be selected, and a more secure installation method can be adopted.

[0061] Referring to Figure 2 and Figure 3 , according to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, it further includes a rotation adjustment assembly 500. The rotation adjustment assembly 500 includes a rotation adjustment rod 510 and a hinge seat 520. The hinge seat 520 is provided on the bottom wall of the seat cushion 200, and the hinge seat 520 provides a stable connection point for one end of the rotation adjustment rod 510. One end of the rotation adjustment rod 510 is connected to the bottom wall of the seat cushion 200 through the hinge seat 520, realizing the rotational connection between the seat cushion 200 and the rotation adjustment rod 510. The other end of the rotation adjustment rod 510 is hinged to the lower end of the connection frame 310, enabling the rotation adjustment rod 510 to play a supporting and adjusting role between the connection frame 310 and the seat cushion 200.

[0062] It can be understood that when the user wants to adjust the inclination of the backrest support assembly 300, by adjusting the rotation adjustment rod 510 to stretch or compress the rotation adjustment rod 510. Since both ends of the rotation adjustment rod 510 are hinged connections, the backrest support assembly 300 can remain stable during the adjustment process without shaking or instability.

[0063] It should be noted that the rotation adjustment rod 510 can be a pneumatic rod, and the rotation adjustment assembly 500 is also equipped with a wire control structure (not shown in the figure). Through the wire control structure, the rotation adjustment rod 510 can be easily unlocked and locked, thereby realizing the precise adjustment of the inclination of the backrest support assembly 300. In addition, it should be noted that using the wire control structure to unlock and lock the pneumatic rod is a conventional technical means that can be used by those skilled in the art, and will not be elaborated here.

[0064] In practical applications, the material, length, and adjustment range of the rotation adjustment rod 510 can be customized according to the specific design of the seat 2000 and the needs of users. For example, for the seat 2000 that requires a larger adjustment range, a longer and stronger rotation adjustment rod 510 can be selected; while for the seat 2000 design that pursues lightness, a shorter and lighter rotation adjustment rod 510 can be selected.

[0065] Referring to Figures 1 to 3, according to the seat support structure 1000 provided by the first aspect embodiment of the present utility model, the upper end of the connecting arm 110 is provided with insertion holes arranged from top to bottom. The insertion holes are designed to facilitate the installation and disassembly of the armrest 600. When the armrest 600 is inserted into the insertion holes, the insertion holes can firmly fix the armrest 600 while allowing the user to adjust the height of the armrest 600 according to needs. The shape and size of the insertion holes match the insertion rod of the armrest 600 to ensure that the armrest 600 can be firmly inserted and maintained in the required position.

[0066] It can be understood that the armrest 600, as an important part of the seat 2000, provides arm support for the user, increasing the comfort and usability of the seat 2000. The armrest 600 is inserted into the insertion holes and can maintain a stable position through the support and fixation of the insertion holes, without moving or shaking due to the user's actions or external forces. In addition, the design of the insertion holes and the armrest 600 also takes into account aesthetics and practicality. The position of the insertion holes can be adjusted according to the specific design of the seat 2000 and the user's needs to ensure the coordination and consistency of the overall appearance of the armrest 600 and the seat 2000. The material, shape, and size of the armrest 600 can also be selected according to the user's preferences and the use of the seat 2000 to provide the best support effect and comfortable experience.

[0067] In practical applications, the installation and disassembly process of the insertion holes and the armrest 600 is simple and convenient, and the user can complete it without using special tools or skills. This provides the user with more flexibility and convenience, allowing them to easily adjust or replace the armrest 600 according to actual needs.

[0068] Refer to Figure 4 , according to the seat 2000 provided by the second aspect embodiment of the present utility model, it includes the seat support structure 1000 as described in any of the above embodiments of the first aspect of the present utility model. The seat 2000 adopts the seat support structure 1000 described in any of the above embodiments. The seat support structure 1000 includes components such as a bracket 100, a connecting arm 110, a seat cushion 200, and an armrest 600. The bracket 100 serves as the skeleton of the seat 2000 and provides stable support; the connecting arm 110 connects the bracket 100 and the seat cushion 200, and the seat cushion 200 provides a comfortable sitting feeling for the user. In addition, according to specific needs, the seat 2000 may also be equipped with a headrest to support the user's head, a lifting gas rod 700 to adjust the height of the seat cushion 200, and a pulley assembly 800 to provide mobility.

[0069] It can be understood that, due to the adoption of the above-mentioned seat support structure 1000, the seat 2000 performs excellently in terms of comfort, stability and practicality. Users can easily adjust the position, height and angle of the seat cushion 200, as well as the position and height of the armrest 600 according to their own needs and preferences, so as to obtain the best sitting experience.
