[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A foldable furniture back panel includes several back panels 101. Each back panel 101 has a slot 102 on both sides in the width direction. A connector plate 103 is inserted into each slot 102. A rotating groove 104 is provided on one side of each connector plate 103 inserted into the slot 102 of two adjacent back panels 101. The rotating grooves 104 are connected to the two ends of a rotating plate 106 by pins 105.

[0024] The above scheme provides the main support plane and structural foundation through the back plate, provides precise accommodation space and smooth sliding path for the plug-in plate through the plug slot, realizes the telescopic connection and relative position adjustment between adjacent back plates through the plug plate, provides a stable installation foundation and flexible rotation range for the rotating plate through the rotating slot, realizes reliable hinge and rotation guidance between the rotating plate and the rotating slot through the pin, and provides a stable rotation hub and force transmission node for the folding movement of adjacent back plates through the rotating plate.

[0025] In this embodiment, preferably, the four corners of the back plate 101 are provided with fixing holes 107, and the two sides of the back plate 101 along its length are provided with two sliding grooves 108.

[0026] The above solution provides multiple mounting points and connection options for the backplate through fixing holes, and provides accurate guidance and stable sliding track restriction for the sliding pin through sliding grooves.

[0027] In this embodiment, preferably, the sliding groove 108 is connected to the insertion groove 102, and the two sliding grooves 108 located opposite each other in the width direction of the back plate 101 are respectively connected to the sliding pin 109.

[0028] The above scheme achieves mechanical linkage and coordinated movement between the sliding pin and the plug plate through the through-hole design of the sliding groove and the plug groove. The sliding pin effectively transmits the force of the spring to the plug plate and realizes motion conversion.

[0029] In this embodiment, preferably, the back plate 101 is made of wood, and the plug plate 103, rotating plate 106 and sliding pin 109 are all made of metal.

[0030] The above solutions maintain the traditional appearance and natural texture of the furniture by using wood for the back panel, enhance the structural strength and surface wear resistance of the connecting parts by using metal for the interlocking plate, improve the operating durability and load capacity of the rotating mechanism by using metal for the rotating plate, and ensure the mechanical rigidity and service life of the transmission components by using metal for the sliding pin.

[0031] In this embodiment, preferably, the sliding pin 109 is located in the insertion groove 102 and is inserted into the end of the insertion plate 103 away from the rotating groove 104, and at least one tension spring is provided in the sliding groove 108.

[0032] The above scheme achieves direct force transmission and motion synchronization through the co-positioning of the sliding pin and the plug plate, and provides elastic force and position restoration function for the plug plate to automatically reset through the tension spring.

[0033] In this embodiment, preferably, the sliding pin 109 is connected to one end of the tension spring, and the other end of the tension spring is connected to the bottom of the sliding groove 108.

[0034] The above scheme achieves power transmission and energy conversion through the connection between the sliding pin and the tension spring, and provides a stable force application point and a reliable fixed foundation through the connection between the tension spring and the bottom of the sliding groove.

[0035] In this embodiment, when the foldable furniture back panel 101 is in use and not folded, the tension spring 110 in the sliding groove 108 is in a taut state. The retraction force generated by the spring continuously acts on the sliding pin 109, causing the sliding pin 109 to slide inward within the sliding groove 108. Since the sliding pin 109 and one end of the insertion plate 103 are in a co-positioned insertion relationship, this movement causes the insertion plate 103 to move inward along the insertion groove 102, so that it is completely housed inside the insertion groove 102 of the back panel 101. At this time, the edges of adjacent back panels 101 are tightly joined, forming a flat and continuous panel structure, which ensures the stability and integrity of the back panel 101 during use and enhances the structural strength and aesthetics of the furniture.

[0036] When folding is required, the user can apply a reverse pulling force to the adjacent back panel 101; this external force overcomes the tension of the tension spring 110 and pushes the plug plate 103 to slide outward along the plug groove 102; the movement of the plug plate 103 is transmitted to the tension spring 110 through the sliding pin 109, causing it to stretch further and store elastic potential energy; as the plug plate 103 gradually extends out of the plug groove 102, the rotating plate 106 connecting the two plug plates 103 rotates relative to each other in the rotating groove 104 through the pin 105; this rotating mechanism provides the necessary degrees of freedom of movement for the back panel 101, enabling the adjacent back panels 101 to fold around the hinge point, achieving space-saving storage.

[0037] The fixing holes 107 at the four corners of the back panel 101 can be used to fix the back panel 101 to the main body of the furniture with fasteners, ensuring that the back panel 101 is firmly installed in the unfolded state. The back panel 101 is made of wood, which maintains the natural texture and beauty of the furniture, while the plug plate 103, rotating plate 106 and sliding pin 109 are made of metal, which significantly improves the wear resistance of moving parts and the service life of the overall structure. The elastic restoring force of the tension spring 110 allows the back panel 101 to automatically return to the unfolded state after the external force is removed, which improves the ease of operation and reliability of the product.

[0038] Through the coordinated work of components such as back panel 101, insertion slot 102, insertion plate 103, rotating slot 104, pin 105, rotating plate 106, fixing hole 107, sliding slot 108, sliding pin 109, and tension spring 110, this design enables the back panel 101 to smoothly switch between two states: stable unfolding and flexible folding. This not only meets the structural stability requirements of furniture but also provides a convenient folding function, embodying a combination of practicality and innovation.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
