[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] An embodiment of the present invention provides a seat seating structure, which is applied to a seat. The specific structure and function of the seat seating structure provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0024] Reference Figures 1 to 4According to the first aspect of the present invention, the seat structure provided by the embodiment comprises: a bracket 100, a seat back 200, a seat plate 300 and an elastic device 400. The bracket 100 is provided with connecting arms 110 extending upward on both sides to provide stable support for the entire seat structure. Connecting plates 210 are provided on both sides of the seat back 200. The connecting plates 210 and the seat back 200 are integrally formed, which is conducive to increasing the structural strength between the connecting plates 210 and the seat back 200. The seat back 200 is arranged between the two connecting arms 110, and the two connecting plates 210 are rotatably connected to the two connecting arms 110 respectively, and the connection forms a first fulcrum 220. The first connecting blocks 310 are provided on the left and right sides of the seat plate 300. The first connecting blocks 310 are rotatably connected to the connecting plates 210, and the connection forms a second fulcrum 320, and the second fulcrum 320 is located in front of the first fulcrum 220. The elastic device 400 comprises a first connecting seat 410, an elastic component 420 and a second connecting seat 430. The first connection seat 410 is connected to the lower end surface of the seat plate 300 , the second connection seat 430 is connected to the bracket 100 , and the elastic component 420 is disposed on the second connection seat 430 and connected to the first connection seat 410 .

[0025] When the user sits down, the user's buttocks press down the seat plate 300, and the seat plate 300 rotates downward around the first fulcrum 220, and the elastic component 420 is compressed. Due to the rotational connection between the first connecting block 310 and the connecting plate 210, the downward pressing action of the seat plate 300 drives the chair back 200 to rotate forward around the first fulcrum 220, so that the chair back 200 fits the user's back. In this process, the compression force of the elastic component 420 provides the user with appropriate support force, so that the chair back 200 can closely fit the user's back curve.

[0026] When the user leans back, the user's back presses the chair back 200 backward, and the chair back 200 rotates backward around the first fulcrum 220. At this time, the elastic component 420 is stretched, and the first connecting block 310 drives the seat plate 300 to rotate upward around the first fulcrum 220, so that the seat plate 300 can fit the user's buttocks. Since the stretching force of the elastic component 420 is related to the user's weight and sitting posture, the elastic component 420 can dynamically adjust the pitch resistance and angle according to the user's weight and sitting posture, achieving a personalized and adaptive support effect.

[0027] According to the seat seating structure provided by the embodiment of the first aspect of the present invention, through the linkage mechanism of the first fulcrum 220 and the second fulcrum 320 between the seat plate 300 and the chair back 200, when the user sits down, the seat plate 300 presses down and drives the chair back 200 to automatically fit the user's back, which significantly improves the fit between the chair back 200 and the back, and improves the comfort and health of the seat. Secondly, the present invention also has an adaptive gravity pitch adjustment function. When the user leans back, the elastic device 400 dynamically adjusts the pitch resistance and angle according to the user's weight and sitting posture. Without manual adjustment, a personalized and adaptive support effect can be achieved, which greatly improves the convenience of use of the seat and the user experience.

[0028] It is understandable that the elastic component 420 can be a spring, an elastic sleeve or other structures with elastic restoring force. When the user stands up and the buttocks and back are separated from the seat structure, the seat plate 300 and the chair back 200 can return to their initial positions under the action of the elastic component 420, so as to facilitate the user to sit next time.

[0029] Reference Figures 2 to 4 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the front side of the bracket 100 is provided with a mounting cylinder 120 extending obliquely upward. The mounting cylinder 120 not only provides a stable accommodation space for the elastic component 420, but also enhances the stability of the structure through its inclined design. The first connecting seat 410 is sleeve-shaped and is sleeved on the outer periphery of the mounting cylinder 120, and can slide up and down relative to the mounting cylinder 120. This allows the first connecting seat 410 to slide accordingly with the up and down rotation of the seat plate 300 when the user sits down or leans back, thereby maintaining the effective function of the elastic component 420. The elastic component 420 is installed in the mounting cylinder 120. The second connecting seat 430 is located below the mounting cylinder 120 and is firmly connected to the bracket 100. Through the connection between the first connecting seat 410 and the bracket 100, the elastic component 420 is confined in the mounting cylinder 120, ensuring its stability and safety during use.

[0030] When the user sits down, the seat plate 300 is pressed down, the first connecting seat 410 slides down accordingly, and the elastic component 420 in the mounting tube 120 is stretched. On the contrary, when the user leans back, the seat plate 300 is lifted up, the first connecting seat 410 slides up, and the elastic component 420 is compressed. Since the elastic component 420 is confined in the mounting tube 120, its telescopic action is smoother and more controllable, thereby providing the user with a more comfortable and stable riding experience. In addition, the inclined design of the mounting tube 120 also enables the force of the elastic component 420 to be more evenly transmitted to the seat plate 300 and the chair back 200, further improving the comfort and support effect of the seat.

[0031] It is understandable that the mounting tube 120 can be integrally formed with the bracket 100, which is beneficial to increase the structural strength.

[0032] Reference Figure 3 and Figure 4 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, a through slot 121 is provided on the opposite side walls of the mounting tube 120, so that the first cross bar 422 can move up and down therein. The elastic component 420 includes a first telescopic body 421, a first cross bar 422, a second telescopic body 423 and a second cross bar 424. Specifically, one end of the first telescopic body 421 is fixed to the second connecting seat 430, and the other end is fixedly connected to the first cross bar 422. One end of the second telescopic body 423 is connected to the first cross bar 422, and the other end is fixedly connected to the second cross bar 424. The second cross bar 424 is firmly fixed to the upper end of the mounting tube 120. This ensures the stability and reliability of the elastic component 420. The two ends of the first cross bar 422 pass through the through slot 121 respectively and are connected to the first connecting seat 410. This enables the first connecting seat 410 to drive the first cross bar 422 to move up and down accordingly when sliding up and down. As the first cross bar 422 moves, the first telescopic body 421 and the second telescopic body 423 will also telescope, thereby providing necessary elasticity and supporting force for the seat seating structure.

[0033] When the user sits down, the seat plate 300 is pressed down, the first connecting seat 410 slides down, and the first telescopic body 421 is compressed and the second telescopic body 423 is stretched through the first cross bar 422. On the contrary, when the user leans back, the seat plate 300 is lifted up, the first connecting seat 410 slides up, and the first cross bar 422 also moves up, thereby stretching the first telescopic body 421 and compressing the second telescopic body 423, so that the seat seating structure can dynamically adjust the pitch resistance and angle according to the user's weight and sitting posture, providing the user with a more comfortable and personalized riding experience.

[0034] Reference Figure 5 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the first telescopic body 421 is composed of a first spring and a first telescopic rod, wherein the first spring is sleeved on the outer periphery of the first telescopic rod. The two ends of the first telescopic rod are respectively connected to the first cross bar 422 and the second connecting seat 430, thereby ensuring the stability of the structure. The two ends of the first spring are respectively fixed to the first cross bar 422 and the second connecting seat 430, thereby providing the necessary elastic restoring force for the telescopic action. Similarly, the second telescopic body 423 also adopts a similar design, and is composed of a second spring and a second telescopic rod. The second spring is sleeved on the outer periphery of the second telescopic rod, and the two ends of the second telescopic rod are respectively connected to the first cross bar 422 and the second cross bar 424. The two ends of the second spring are also respectively fixed to the first cross bar 422 and the second cross bar 424, thereby further enhancing the elasticity and stability of the structure.

[0035] When the user sits down or reclines, the first connecting seat 410 drives the first crossbar 422 to move up and down. Due to the connection between the first crossbar 422 and the first telescopic rod and the second telescopic rod, this up and down movement is converted into the telescopic movement of the first telescopic rod and the second telescopic rod. At the same time, the first spring and the second spring are also compressed or stretched as the telescopic rods are extended and retracted, thereby providing continuous and adjustable elastic support for the seat seating structure.

[0036] Reference Figure 4 and Figure 5 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the elastic component 420 includes two first telescopic bodies 421 and two second telescopic bodies 423. Specifically, the two first telescopic bodies 421 are installed in parallel between the second connecting seat 430 and the first cross bar 422. This not only enhances the supporting strength of the elastic component 420, but also improves its stability and durability. The two first telescopic bodies 421 jointly bear the pressure from the seat plate 300 and the chair back 200, ensuring that the seat can maintain stable performance during long-term use. Similarly, the two second telescopic bodies 423 are also arranged in parallel between the first cross bar 422 and the second cross bar 424. This further enhances the elastic restoring force of the elastic component 420, so that the seat can respond more sensitively when the user sits down or reclines, and provides more fitting and comfortable support. The parallel arrangement of the two second telescopic bodies 423 also helps to disperse pressure, reduce the wear of a single component, and thus extend the service life of the seat.

[0037] When the user sits down, the two first telescopic bodies 421 are compressed at the same time, providing a stable support force for the seat plate 300. When the user leans back, the two second telescopic bodies 423 are compressed at the same time, dynamically adjusting the pitch resistance and angle according to the user's weight and sitting posture. This dual telescopic body design makes the seat structure more outstanding in providing comfort and support, which can meet the needs of different users and provide a personalized and adaptive riding experience.

[0038] Reference Figure 4 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, first connecting parts 411 are provided on both sides of the first connecting seat 410. Specifically, the lower end surface of the first connecting part 411 is arranged with a plurality of first screw holes arranged at intervals. The design of the first screw holes allows the screws to be easily inserted and fixed, thereby firmly mounting the first connecting seat 410 on the lower end of the seat plate 300. The provision of multiple screw holes also provides room for adjustment, allowing fine-tuning to be performed as needed during the installation process to ensure that the connection between the first connecting seat 410 and the seat plate 300 is both stable and accurate.

[0039] During installation, the first connection seat 410 can be reliably fixed to the lower end of the seat plate 300 by simply passing the screw through the first screw hole and tightening it. This connection method is not only simple and easy, but also provides sufficient strength and stability to withstand various forces and pressures generated by users when using the seat.

[0040] In addition, the connection between the first connection portion 411 and the seat plate 300 can be further strengthened by other auxiliary means, such as using washers, locking nuts, etc. These auxiliary means can improve the tightness and durability of the connection, ensuring that the seat structure maintains stable and reliable performance in long-term use.

[0041] Reference Figure 2 and Figure 3 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the side walls opposite to the first connecting seat 410 are provided with guide grooves 412, and specifically, the outer walls opposite to the mounting tube 120 are provided with guide rods 122. The guide rods 122 are inserted into the guide grooves 412 of the first connecting seat 410. When the first connecting seat 410 slides up and down, the guide rods 122 move along the guide grooves 412, providing stable support and guidance for the first connecting seat 410. This not only prevents the first connecting seat 410 from deflecting or shaking during the sliding process, but also ensures that the elastic component 420 can always remain in the correct position and working state.

[0042] Reference Figure 3 and Figure 4 According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the side wall opposite to the mounting tube 120 is provided with a threaded connection seat 432, and the end of the guide rod 122 is threadedly connected to the threaded connection seat 432. Specifically, the end of the guide rod 122 is designed to be a threaded shape that can match the threaded connection seat 432. During the installation process, the first connection seat 410 is first sleeved onto the mounting tube 120, and then the end of the guide rod 122 is passed through the guide groove 412 and screwed into the threaded connection seat 432, and the end of the guide rod 122 is tightly connected by rotating it, so that a firm connection between the mounting tube 120 and the guide rod 122 can be achieved. This threaded connection method is not only simple and easy, but also provides sufficient strength and stability, and can withstand various forces and pressures generated during the use of the seat.

[0043] Reference Figures 1 to 3According to the seat seating structure provided by the embodiment of the first aspect of the present invention, the seat plate 300 is provided with a second connecting block 330, the second connecting block 330 is located at the rear side of the first connecting block 310, and a limiting groove 111 is provided on the side of the connecting arm 110 facing the second connecting block 330, and the side of the connecting arm 110 facing the second connecting block 330 is designed with the limiting groove 111. This limiting groove 111 not only provides a precise plug-in position for the limiting column 340 on the second connecting block 330, but also ensures that the seat plate 300 can maintain a stable motion trajectory during forward and backward movement or rotation. The limiting column 340 is connected to the second connecting block 330, and the limiting column 340 can be tightly plugged into the limiting groove 111 of the connecting arm 110. During the installation process, the alignment and plugging of the limiting column 340 and the limiting groove 111 ensure the stability and flexibility of the connection between the seat plate 300 and the connecting arm 110.

[0044] When the seat plate 300 moves forward or backward or rotates, the limiting column 340 moves along the limiting groove 111, providing stable support and guidance for the seat plate 300. This not only prevents the seat plate 300 from deflecting or shaking during movement, but also ensures that the seat seating structure can always remain in the correct position and working state.

[0045] The seat provided in the embodiment according to the second aspect of the present invention has all the beneficial effects of the embodiment according to the first aspect of the present invention.

[0046] It is understandable that the seat also includes a seat cushion arranged on the seat plate 300 and a pulley frame arranged under the bracket 100, etc., which will not be described in detail here.
