[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figs. 1-3 As shown, the sofa pneumatic storage bracket involved in this embodiment includes a lower connecting crossbar 1 and an upper connecting crossbar 2 located above the lower connecting crossbar. A short support rod 3 near the front end and a gas spring 4 near the rear end are provided between the lower connecting crossbar 1 and the upper connecting crossbar 2. A long support rod 5 with one end hinged to the lower connecting crossbar and the other end hinged to the upper connecting crossbar is provided between the gas spring 4 and the short support rod 3. One end of the short support rod 3 and the gas spring 4 are both hinged to the lower connecting crossbar 1 and the other end is hinged to the upper connecting crossbar 2.

[0020] In this embodiment, by adding a long support rod 5 with one end hinged to the lower connecting crossbar and the other end hinged to the upper connecting crossbar between the gas spring 4 and the short support rod 3, the upper connecting crossbar 2 can tilt up or down relative to the lower connecting crossbar 1 while the gas spring 4 is extending and retracting. The long support rod 5 not only provides auxiliary transmission but also plays a role in local support and reinforcement, making the overall stability of the support frame higher.

[0021] Example 2

[0022] See Figs. 1-3 As shown, this embodiment of a sofa pneumatic storage bracket, based on embodiment 1, is further configured such that a terminal damping assembly 100 is provided on the lower connecting crossbar 1 between the short support rod and the long support rod, and the terminal damping assembly 100 is arranged close to the long support rod 5; the terminal damping assembly 100 includes damping side plates 6 on the left and right sides of the lower connecting crossbar, and a base support 7 is connected between the damping side plates 6 at the top of the lower connecting crossbar. A pressure plate 8 is provided at the end of the base support 7 facing the long support rod, and the pressure plate 8 is upward and away from the long support rod. The support rod extends, and the lower connecting crossbar 1 has a limiting hole 9 that extends forward and backward. A movable limiting plate 10 is slidably connected in the limiting hole 9. The movable limiting plate 10 is connected to the base support 7. A fixed limiting plate 11 is provided at the end of the movable limiting plate 10 facing away from the long support rod. The fixed limiting plate 11 is connected to the lower connecting crossbar. An elastic element 12 is provided between the fixed limiting plate 11 and the movable limiting plate 10. The elastic element 12 is a compression spring with one end abutting against the fixed limiting plate and the other end abutting against the movable limiting plate. A reinforcing rib plate 13 is connected between the pressure plate 8 and the base support 7.

[0023] Furthermore, the end of the damping side plate 6 that is not connected to the base support 7 is provided with a serration 14 located at the bottom of the lower connecting crossbar.

[0024] In this embodiment, when the gas spring 4 shortens, the upper connecting crossbar 2 swings downward relative to the lower connecting crossbar 1. During this time, the short support rod 3 and the long support rod 5 move in tandem. Before the gas spring 4 shortens to its shortest stroke position, the long support rod 5 contacts the pressure plate 8. Part of the force generated by the closing of the bracket acts on the pressure plate 8, causing the pressure plate 8 and the connected base support 7 to move laterally on the lower connecting crossbar 1. This causes the movable limiting plate 10 to move closer to the fixed limiting plate 11, compressing the elastic element 12. This achieves a secondary deceleration function during the final rotation of the bracket, effectively preventing foreign objects from being clamped by the bracket, making it safer and more reliable to use.

[0025] The toothed 14 prevents the end damping component 100 from disengaging when it moves laterally relative to the lower connecting crossbar 1, thus serving as a sliding limit.

[0026] The sofa pneumatic storage bracket involved in this utility model has a long support rod in the middle that provides support and transmission, which ensures that the upper cabinet panel can be opened and closed while the load-bearing capacity is stronger and the use is safer and more stable. On one side of the long support rod, there is a terminal damping component that is connected to the lower crossbar for elastic lateral movement, which can prevent the upper cabinet panel from closing too quickly, prevent pinching, and improve safety. The overall function is complete and the practicality is strong.
