[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-3 As shown, a synchronously movable sofa bracket comprises a symmetrically arranged telescopic bracket 1, one end of the telescopic bracket 1 is equipped with a symmetrically arranged backrest bracket 2, and the other end is equipped with a symmetrically arranged leg support bracket 3, the symmetrically arranged telescopic brackets 1 are connected to a first connecting rod 5 through a fixing rod 4, and the fixing rod 4 is provided with a tension spring 6 connected to one side of the telescopic bracket 1.

[0024] In this embodiment, a first connecting rod 5 is provided between the telescopic brackets 1 to maintain synchronization during the extension process of the telescopic bracket 1. At the same time, a tension spring 6 connected to one side of the telescopic bracket 1 is provided on the fixed rod 4 to provide a reset force after the telescopic bracket 1 is extended to help the bracket return to its original position. In this way, the telescopic bracket 1 can be ensured to maintain the same starting point for extension, and to ensure that it can maintain synchronous extension during the next extension.

[0025] Furthermore, the fixing rod 4 is fixedly arranged at one end of the telescopic bracket 1 close to the backrest bracket 2 by means of a fastener, and a telescopic motor 7 is fixed at the middle position of the fixing rod 4 .

[0026] Furthermore, a connecting piece 8 for connecting the telescopic bracket 1 is fixedly provided on the first connecting rod 5 .

[0027] Furthermore, the connecting piece 8 is a connecting piece that has been bent, and one side in the horizontal direction thereof is connected to the first connecting rod 5 through a fastener, and one side in the vertical direction thereof is connected to the telescopic bracket 1 through a fastener.

[0028] The number of fasteners used to connect the connecting piece 8 with the telescopic bracket 1 and the first connecting rod 5 is at least two, which can ensure that the first connecting rod 5 is firmly installed between the telescopic brackets 1 without loosening.

[0029] Furthermore, one end of the tension spring 6 is fixedly arranged at the positions of both ends of the fixing rod 4 close to the telescopic bracket 1, and the other end is fixed on the opposite side between the symmetrically arranged telescopic brackets 1.

[0030] By setting the tension spring 6, the telescopic bracket 1 can be kept at the same starting point for extension. During the extension process of the telescopic bracket 1, as the extension distance of the telescopic bracket 1 gradually increases, a reset pulling force can be gradually generated on the telescopic bracket 1. In combination with the connecting rod, the symmetrically arranged telescopic bracket 1 can always be in a synchronous extension state during the extension process.

[0031] Furthermore, a second connecting rod 9 connected to the telescopic end of the telescopic motor 7 is provided between the leg support brackets 3 .

[0032] Furthermore, the telescopic end of the telescopic motor 7 is hinged to the middle part of the second connecting rod 9. The telescopic motor 7 is connected to the middle part of the second connecting rod 9, which can prevent the uneven state caused by the unbalanced force on the second connecting rod 9 during the extension of the telescopic bracket 1, thereby affecting the extension of the telescopic bracket 1.

[0033] Furthermore, the telescopic bracket 1 is also provided with a frame mounting beam 10 for mounting a sofa cushion frame.

[0034] Furthermore, the backrest bracket 2 is movably mounted on one end of the telescopic bracket 1, and a mounting arm 11 for mounting a sofa backrest is provided thereon.

[0035] Furthermore, the leg support bracket 3 is installed at the other end of the telescopic bracket 1, and a mounting support plate 12 for mounting a sofa leg support is installed thereon.

[0036] The working process and principle of the utility model are as follows:

[0037] When the telescopic motor 7 is started, the telescopic bracket 1 is driven to extend or contract. By installing the first connecting rod 5 between the symmetrically arranged telescopic brackets 1, it helps to maintain a high degree of synchronization of the telescopic bracket 1 during activity and increases the activity stability of the telescopic bracket 1. Since the telescopic brackets 1 are connected by the first connecting rod 5 and the tension spring 6, the telescopic bracket 1 can move synchronously to maintain the consistency of extension or contraction. When the telescopic bracket 1 is extended, the tension spring 6 simultaneously generates a pulling force on the telescopic brackets 1 on both sides, which helps to maintain the synchronous extension of the brackets on both sides. After the extension is completed, the tension spring 6 provides a reset force to help the telescopic bracket 1 return to its original position, ensuring that the telescopic bracket 1 can stably remain in the initial state when it does not need to be extended; the synergistic effect of the second connecting rod 9 and the telescopic motor 7 ensures that the leg support bracket 3 can also respond synchronously. The design of the entire structure ensures the stability and synchronization of the sofa when changing its shape, avoiding shaking and asynchronism.

[0038] The above detailed description of the specific implementation of the utility model is only used as an example. The utility model is not limited to the specific implementation described above. The technicians in the industry should understand that the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
