[0002] The existing Chinese utility model patent application number is 2024200752036, and the name is "An Improved High-legged Zero-wall Iron Frame". When switching between the TV posture and the lying posture, the driving connecting rod drives the front and rear support rods 2, the seat frame mounting plate, and the side connecting rod 2 to make oblique movements, and the side connecting rod 2 drives the front and rear rotating parts to rotate. Since the side connecting rod 2 and the front and rear rotating parts are assembled by riveting, there is a difference in friction at each riveting point, and the rotation speeds of the front and rear rotating parts on both sides are different, resulting in different expansion or folding speeds of the extension components on both sides, that is, the extension components on both sides are not synchronized, causing the iron frame to twist when switching between states, affecting product quality. Utility Model Content

[0013] 1. Install a balance bar between at least one rotating part (the front rotating part or the rear rotating part) to ensure that the rotating parts on both sides rotate synchronously. At the same time, with the assistance of the tension springs on both sides, balance the extension resistance of the extension components on both sides, thereby ensuring the synchronization of the left and right extension components and eliminating the twisting phenomenon of the functional iron frame when switching states, thereby improving product quality.

[0022] like Figure 2 As shown, a second embodiment of a balancing mechanism 3 includes a balancing rod 31, which is installed between two front rotating parts 214. The front rotating parts are bent to form front supporting feet 2141 for installing the balancing rod. Tension springs 32 are arranged on both sides of the balancing rod.

[0023] like Figure 3 As shown, a third embodiment of a balancing mechanism 3 includes a balancing rod 31, which is installed between two front rotating members 214 and two rear rotating members 215 at the same time. The front rotating member is bent into a front support foot 2141 for installing the balancing rod, and the rear rotating member is bent into a rear support foot 2151 for installing the balancing rod. Tension springs 32 are arranged on both sides of the balancing rod connected to the rear rotating member, and the front end of the tension spring is connected to the balancing rod. The balancing rod has a first through hole 311 for installing the tension spring, and the rear end of the tension spring is connected to a fixing member 33, which is a support rod installed between the assembly side plates on both sides, and the support rod has a second through hole 331 for connecting the tension spring.

[0024] In addition, there are other embodiments: for example, on the basis of the balance pole being installed between the two front rotating members and the two rear rotating members at the same time, a tension spring can be installed between the balance pole connected to the front rotating member and the support pole, or a tension spring can be installed between the support pole and the two balance poles at the same time.

[0025] like Figure 4 As shown, a functional iron frame adopting a balancing mechanism of embodiment 1 includes two symmetrical assembly side panels 1, an extension component 2 is arranged on the inner side of the assembly side panels, the extension component includes a front support member 211 and a rear support member 212 pivotally connected to the assembly side panels, the upper part of the front support member 1 is pivotally connected to the front rotating member 214, the upper part of the rear support member 1 is pivotally connected to the rear rotating member 215, and the rear rotating members on both sides are connected by a balancing mechanism 3.

[0026] The specific working process and principle of the functional iron frame using a balancing mechanism:

[0027] When the TV posture is converted to the lying posture, the telescopic end of the push rod motor continues to extend, and the leg mechanism, the seat frame mounting plate, the driving connecting rod, the second front support member, the second rear support member, and the second side connecting rod member move obliquely upward as a whole, and the front and rear rotating members rotate clockwise. Since the balance bar connects the two rear rotating members as a whole, the synchronization of the two rear rotating members is ensured. At the same time, the extension component on the side with smaller extension resistance slows down the extension speed under the action of the tension spring on the same side.

[0028] When the lying position is converted to the TV position, the telescopic end of the push rod motor contracts, the leg mechanism, the seat frame mounting plate, the driving connecting rod, the second front support member, the second rear support member, and the second side connecting rod member move obliquely downward as a whole, and the front and rear rotating members rotate counterclockwise. Since the balance bar connects the two rear rotating members as a whole, the synchronization of the two rear rotating members is ensured. At the same time, the extension component on the side with greater extension resistance accelerates the retraction speed under the action of the tension spring on the same side.

[0029] The utility model increases constraints at the rotation points of the extension assemblies on both sides to ensure that the rotating parts on both sides rotate at the same time, and balances the extension resistance of the extension assemblies on both sides through tension springs, thereby ensuring the synchronization of the left and right extension assemblies, eliminating the twisting phenomenon of the functional iron frame when the state is switched, thereby improving product quality.
