[0002] As global climate change and environmental issues become increasingly severe, the construction industry is turning to more environmentally friendly and sustainable materials and technologies. Ecological doors use environmentally friendly building materials, such as recycled materials, bio-based materials, or materials with low volatile organic compound emissions, which reduces the impact on the environment. Modern consumers' pursuit of health, environmental protection and sustainable lifestyles continues to increase, which continuously drives the market to transform to greener products and services. Ecological doors, as part of green building materials, are in line with this trend and are favored by more and more consumers.

[0003] The patent with authorization publication number CN219993543U discloses an energy-saving composite entrance door with multi-material finishes, including a composite door frame, a composite door leaf and a fireproof fixing plate for hingedly connecting the composite door frame and the composite door leaf, the composite door leaf including a centrally arranged fireproof door core panel, a cold-rolled steel plate coated on the periphery of the fireproof door core panel, a fiberboard symmetrically arranged on both sides of the cold-rolled steel plate, a detachable composite decorative panel coated on the periphery of the fiberboard and a composite edging for fixing the composite decorative panel, the composite decorative panel including a wood veneer panel and a metal panel, the metal panel is embedded in the wood veneer panel, the composite edging is composed of a steel side edging and an aluminum decorative edging, and the steel side edging is embedded in the aluminum decorative edging.

[0004] The above patented design of the entrance door adopts a composite edging design, which effectively improves the fire resistance and avoids the problems of profile melting, high temperature diffusion and smoke leakage in the event of a fire. The composite assembly of decorative panels enables the door body to present a variety of appearance styles.

[0029] like Figure 6 , Figure 8 and Fig. 9 As shown, the multi-material finished composite energy-saving entrance door also includes a locking assembly 7, which includes a guide tube 701, a locking piece 702, a memory alloy spring II 703 and a heat-conducting rod II 704. The guide tube 701 is symmetrically arranged in each of the installation frames 501, and the interior of the guide tube 701 is sealed and slidably installed with a locking piece 702, and the locking piece 702 is composed of a disc, a connecting rod and a wedge block. A memory alloy spring II 703 is arranged between the guide tube 701 and the locking piece 702, and a heat-conducting rod II 704 is connected between the installation frames 501, and the heat-conducting rod II 704 is a U-shaped folding rod.

[0030] like Figure 8 and Fig. 9 As shown, one side of the end of the rack frame 503 is provided with a groove, the wedge block of the locking piece 702 is embedded in the groove, and the side of the wedge block of the locking piece 702 away from the heat-conducting rod II 704 is an inclined surface, and the memory alloy spring II 703 is elongated by heat and can drive the locking piece 702 to slide away from the groove of the rack frame 503, thereby releasing the lock of the rack frame 503; the heat-conducting frame 601, the heat-conducting rod I 603 and the heat-conducting rod II 704 all have high thermal conductivity, and the heat-conducting frame 601, the heat-conducting rod I 603 and the heat-conducting rod II 704 are specifically made of copper-aluminum alloy.

[0031] like Figure 1 and Figure 6As shown, the multi-material finished composite energy-saving entrance door also includes a heat conductive member 9, and the heat conductive member 9 includes a heat conductive strip 901, a heat conductive plate 902 and a heat conductive connecting plate 903. The heat conductive strip 901 is embedded in the side wall of the installation door frame 1, and the end of the heat conductive strip 901 is in contact with the heat conductive frame 601, and the heat conductive rod II 704 is also in contact with the heat conductive strip 901. The side wall of the door leaf frame 2 is embedded with a heat conductive plate 902, and a heat conductive connecting plate 903 is connected between the heat conductive strip 901 and the heat conductive plate 902. The heat conductive member 9 will sensitively sense that the temperature will rise rapidly after a fire.

[0032] When the present entrance door is in use, different decorative panels can be assembled on the decorative assembly frame 4 as needed. When a fire occurs, the fireproof door core plate 201 can isolate the temperature and fire inside and outside the door when a fire occurs, and the high temperature caused by the fire, whether it is first conducted to the heat-conducting strip 901 or the heat-conducting plate 902, can be mutually conducted through the heat-conducting connecting plate 903. The heat-conducting strip 901 after being heated up conducts the heat to the heat-conducting rod II 704 and the heat-conducting frame 601, and the heat-conducting rod II 704 can conduct the heat to the guide tube 701. The guide tube 701 is heated up and causes the memory alloy spring II 703 to extend and push the locking piece 702 to move, and finally causes the locking piece 702 to release the locking effect on the rack frame 503. At the same time, the heat-conducting frame 601 conducts the heat through the heat-conducting rod I 603 The piston sleeve 504 is filled with a heat-sensitive adhesive. At this time, the temperature inside the piston sleeve 504 rises, causing the memory alloy spring Ⅰ602 inside it to extend due to the heat. The extended memory alloy spring Ⅰ602 will push the piston rod 505 to move. The moving piston rod 505 will simultaneously drive the rack frame 503 to move. The rows of teeth on the side of the moving rack frame 503 will mesh and drive the corresponding gear 502 to rotate. The rotating gear 502 will synchronously drive the corresponding rotating shaft 401 to drive the facing assembly frame 4 to flip 180 degrees, so that the decorative panel decorated on the outside of the decorative assembly frame 4 can automatically flip inward and retract into the door frame 2 when encountering a fire, and the back of the fire-proof and high-temperature resistant decorative assembly frame 4 can be replaced with the surface, thereby automatically protecting the decorative panel on the entrance door and minimizing the impact of the fire on the entrance door.

[0033] Embodiment 2: Based on embodiment 1, Figure 3-Figure 5 As shown, a limiting member 8 is provided on the decorative assembly frame 4, and the limiting member 8 is used to limit the decorative panel installed on the decorative assembly frame 4. The limiting member 8 includes a mounting block 801, a wedge-shaped long block 802 and an elastic member 803. The upper and lower parts of the front side of each decorative assembly frame 4 are fixedly connected with a plurality of mounting blocks 801. The mounting block 801 is slidably mounted with a wedge-shaped long block 802 through a guide rod, and an elastic member 803 is provided between the wedge-shaped long block 802 and the mounting block 801.

[0034] In the process of assembling the required decorative panel into the decorative assembly frame 4, the decorative panel will be pressed on the wedge-shaped long blocks 802 on the upper and lower sides, so that the two corresponding wedge-shaped long blocks 802 on the same decorative assembly frame 4 will overcome the elastic force of the elastic member 803 and open in the direction away from each other. When the decorative panel is completely installed in the decorative assembly frame 4, the wedge-shaped long block 802 that has lost the pressure of the decorative panel will be reset and retracted under the action of the spring, and the decorative panel will be stably limited in the decorative assembly frame 4, thereby improving the stability of the decorative panel after being installed in the decorative assembly frame 4. When multiple decorative panels are assembled side by side in the decorative assembly frame 4, the locking member 702 is initially restricted in the rack frame 503, so that the rotation of the gear 502 is limited by the meshing of multiple rows of teeth on the rack frame 503, so that the decorative assembly frame 4 and the decorative panel assembled thereon cannot be pushed at will when the entrance door is in normal use, thereby ensuring the normal decorative effect of the decorative panel.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
