Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 The present invention provides a technical solution: a leisure chair, including a seat 1, a backrest 8, armrest components, and support components. Two fixing plates 3 are fixedly connected above the seat 1 and near the side edge. The backrest 8 is rotatably connected to the two fixing plates 3.

[0022] Fixed frames 14 are fixedly installed on both ends of the seat 1. The armrest components include two side armrest assemblies, which are located on both sides of the backrest 8 and above the two fixed frames 14. Each side armrest assembly includes an armrest 10, one end of which is rotatably connected to the backrest 8. A second rotating shaft 9 passes through the end of the armrest 10 and is rotatably connected to the armrest 10. One end of the second rotating shaft 9 is fixedly connected to the backrest 8.

[0023] The support components include two X-shaped folding frames 22, which are respectively installed below the two fixed frames 14. The handrail 10 is connected to the X-shaped folding frames 22 by transmission. After the handrail 10 rotates partially on the back plate 8, it pushes the X-shaped folding frames 22 to fold or unfold.

[0024] Specifically, a first rotating shaft 4 is fixedly installed at the lower edge of the back plate 8. The two ends of the first rotating shaft 4 pass through two fixing plates 3 respectively, and the first rotating shaft 4 is rotatably connected to the fixing plates 3.

[0025] The back panel 8 can rotate around the first rotating shaft 4, thereby achieving a folding action between the back panel 8 and the seat panel 1. When the chair needs to be folded, the back panel 8 moves closer to the seat panel 1 through the rotation of the first rotating shaft 4, eventually fitting snugly against the seat panel 1 to complete the folding process. When the chair needs to be unfolded, the back panel 8 gradually moves away from the seat panel 1 through the reverse rotation of the first rotating shaft 4, returning to the unfolded state. The first rotating shaft 4 serves as the connecting hub between the back panel 8 and the fixed plate 3. Its rotational connection ensures smooth movement of the back panel 8 during folding and unfolding, while also guaranteeing a stable connection between the back panel 8 and the fixed plate 3, preventing loosening or detachment during use.

[0026] More specifically, a pin 6 is inserted into the fixing plate 3 and the two are slidably connected. A spring 7 is sleeved on the outer wall of the pin 6. One end of the spring 7 is fixedly connected to the pin 6, and the other end of the spring 7 is fixedly connected to the fixing plate 3. Two slots 5 are opened on the outer wall of the first rotating shaft 4, and one end of the pin 6 is inserted into the slot 5 on the first rotating shaft 4.

[0027] This structural design serves to position the back panel 8. When the back panel 8 is in the unfolded state, the pin 6, under the elastic force of the spring 7, inserts into a slot 5 on the first rotating shaft 4, thus fixing the back panel 8 in the unfolded position and providing stable support for the user's back. When the chair needs to be folded, pulling the pin 6 outward disengages it from the slot 5. At this time, the spring 7 is stretched, allowing the back panel 8 to rotate around the first rotating shaft 4. When the back panel 8 is folded to contact the seat 1, another slot 5 on the first rotating shaft 4 rotates to the position of the pin 6. At this time, the spring 7 returns to its original position, causing the pin 6 to insert into the slot 5, fixing the back panel 8 in the folded position. This cooperation structure of the pin 6 and the slot 5 not only achieves stable positioning of the back panel 8 in different states, but also is simple and convenient to operate. Users only need to gently pull the pin 6 to complete the folding and unfolding positioning of the back panel 8, improving the ease of use of the chair.

[0028] Specifically, the support component also includes a sixth rotating shaft 23, which passes through the middle of the two X-shaped folding frames 22 respectively, and is rotatably connected to the X-shaped folding frames 22.

[0029] The sixth rotating shaft 23, serving as a connecting component of the X-shaped folding frame 22, provides support and connection. The sixth rotating shaft 23 runs through the middle of the X-shaped folding frame 22, allowing it to rotate around it. This design not only ensures the stability of the X-shaped folding frame 22 during folding and unfolding but also makes its folding action smoother. The inclusion of the sixth rotating shaft 23 makes the folding and unfolding of the X-shaped folding frame 22 more flexible, while also improving the overall stability and lifespan of the lounge chair.

[0030] More specifically, the X-shaped folding frame 22 includes a first support leg, a fixing block 19, a second support leg, and a sliding block 20. A second sliding groove is provided on the fixing frame 14, and a guide rod 15 is installed within the second sliding groove of the fixing frame 14. The fixing block 19 is fixedly connected to the fixing frame 14, and the sliding block 20 is slidably installed within the second sliding groove of the fixing frame 14. The guide rod 15 passes through the sliding block 20, and the two are slidably connected. The middle portion of the first support leg and the middle portion of the second support leg are hinged together by a sixth rotating shaft 23. The upper end of the first support leg is hinged to the fixing block 19, and the upper end of the second support leg is hinged to the sliding block 20 by a fifth rotating shaft 21.

[0031] This structural design enables the X-shaped folding frame 22 to fold and unfold. In the unfolded state, the first and second support legs are connected by the sixth rotating shaft 23, forming a stable support structure that provides support for the lounge chair. When the lounge chair needs to be folded, the sliding block 20 slides within the second groove, causing the second support leg to rotate around the sixth rotating shaft 23. Simultaneously, the first support leg also rotates around the sixth rotating shaft 23, lowering the height of the X-shaped folding frame 22 and achieving folding. The guide rod 15 serves a guiding function, ensuring the stability of the sliding block 20 during sliding and preventing it from shifting or jamming, thus ensuring the smooth folding action of the X-shaped folding frame 22. This design of the X-shaped folding frame 22 is not only simple in structure but also has a significant folding effect, greatly reducing the volume of the lounge chair after folding and improving space utilization.

[0032] More specifically, the side armrest assembly also includes a first connecting rod 13 and a second connecting rod 17. A first sliding groove 11 is provided on the armrest 10. One end of the first connecting rod 13 is slidably connected to the first sliding groove 11 of the armrest 10, and the first connecting rod 13 is rotatably connected to the armrest 10 through the first sliding groove 11. The other end of the first connecting rod 13 is rotatably connected to the middle of the fixed frame 14. One end of the second connecting rod 17 is rotatably connected to the middle of the first connecting rod 13, wherein this end of the second connecting rod 17 is rotatably connected to the middle of the first connecting rod 13 through a fourth rotating shaft 18. The other end of the second connecting rod 17 is hinged to a sliding block 20.

[0033] This structural design enables a transmission connection between the armrest 10 and the X-shaped folding frame 22. When the armrest 10 is pulled, it drives the first connecting rod 13 to slide via the first sliding groove 11. The sliding of the first connecting rod 13 then pushes the sliding block 20 to slide within the second sliding groove via the second connecting rod 17, thereby causing the X-shaped folding frame 22 to fold or unfold. This transmission connection allows the user to easily fold the X-shaped folding frame 22 while pulling the armrest 10, without complicated operations, greatly improving the ease of use of the lounge chair. At the same time, this structure also ensures the stability and reliability of the transmission process, enabling the X-shaped folding frame 22 to fold accurately.

[0034] More specifically, one end of the first connecting rod 13 is fixedly connected to a sliding rod 12, and the other end of the first connecting rod 13 is fixedly connected to a third rotating shaft 16. The end of the sliding rod 12 is inserted into the first sliding groove 11 of the handrail 10. Both ends of the third rotating shaft 16 are rotatably connected to the fixed frame 14.

[0035] The sliding rod 12 and the third rotating shaft 16 further optimize the connection structure between the armrest 10 and the first connecting rod 13. The sliding of the sliding rod 12 within the first groove 11 allows the movement of the armrest 10 to be transmitted more smoothly to the first connecting rod 13. The third rotating shaft 16 ensures a stable rotational connection between the first connecting rod 13 and the fixed frame 14, ensuring that the first connecting rod 13 maintains a good state of motion during operation and preventing jamming or loosening. This structural design not only improves transmission efficiency but also enhances the overall stability and lifespan of the lounge chair.

[0036] Specifically, a seat cushion 2 is detachably installed on the seat 1.

[0037] Users can choose different materials and thicknesses of seat cushion 2 according to different seasons or personal preferences, thus obtaining a more comfortable user experience. At the same time, the removable seat cushion 2 also makes it easy to store after the lounge chair is folded, further improving space utilization.

[0038] In use, pull out the pin 6 and stretch the spring 7 to disengage the pin 6 from the slot 5, then move it to the right (see reference). Figure 1 Pulling the armrest 10 to the side causes the armrest 10 to rotate the backrest 8 around the first rotating shaft 4 towards the side where the seat cushion 2 is located, via the second rotating shaft 9. At this time, the pin 6 contacts the outer wall of the first rotating shaft 4. During the pulling of the armrest 10, the sliding rod 12 slides within the first sliding groove 11 and drives the first connecting rod 13 to rotate around the third rotating shaft 16. During the rotation of the first connecting rod 13, the sliding block 20 is pushed to the right on the guide rod 15 via the second connecting rod 17 (see reference). Figure 1(Right side) Slide, since the fixed block 19 is fixed, when the sliding block 20 slides, it will drive the upper end of the second support leg of the X-shaped folding frame 22 to move, the X-shaped folding frame 22 folds upward, and the overall height of itself decreases.

[0039] refer to Figure 4 When the armrest 10 is pulled, its trajectory is a rotation around the first rotating axis 4 while maintaining a horizontal position. When the armrest 10 contacts the fixed plate 3, the backrest 8 rotates to contact the seat cushion 2. At this time, the next slot 5 on the first rotating axis 4 rotates to the pin 6, and the spring 7 returns to its original position, pulling the pin 6 into the slot 5 to fix the backrest 8 in place. The chair then folds into the desired position. Figure 4 The state shown.

[0040] This invention achieves automatic folding of the back panel 8 and the X-shaped folding frame 22 by connecting the armrest 10 to the X-shaped folding frame 22 during the pulling of the armrest 10. This design greatly simplifies the folding operation; users only need to pull the armrest 10 to quickly fold the chair, eliminating the need for complex pressing or rotating operations, thus improving ease of use. Furthermore, by reducing the number of steps and the amount of force required, it also reduces potential user fatigue during the folding process, enhancing the overall user experience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
