[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0037] This embodiment describes an entrance door with an embedded lock 2, such as... Figure 1-6 As shown, it includes a door body 1 and a lock 2.
[0038] The door 1 is provided with a handle assembly 11 on the outdoor side, and the handle assembly 11 is recessed inward relative to the surface of the door 1.
[0039] The lock 2 includes a front panel 21, a rear panel 22, and an electric lock body 23;
[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the front panel 21 includes a front handle panel 211, a fingerprint sensor 212, and a mounting base 213. The mounting base 213 is mounted on the handle assembly 11, the front handle panel 211 is mounted on the mounting base 213, and the fingerprint sensor 212 is mounted on the front handle panel 211.
[0041] like Figure 2 , Figure 3 and Figure 5As shown, the rear panel 22 includes a handle box 221, a rear handle panel 222, and a button 223. The handle box 221 is embedded in the interior side of the door 1, and the rear handle panel 222 is fixedly installed in the handle box 221. The rear handle panel 222 has a handle hole 2221 corresponding to the handle box 221. The button 223 is installed in the rear handle panel 222.
[0042] The electric lock body 23 is installed inside the door body 1. The fingerprint sensor 212 and the button 223 are respectively connected to the electric lock body 23 to send an unlocking signal to the electric lock body 23.
[0043] This utility model employs an embedded installation structure for the front panel 21 and rear panel 22 of the lock 2, making them almost flush with the surface of the door 1. Therefore, after the lock 2 is installed, both the interior and exterior surfaces of the door 1 are relatively flat, facilitating packaging and transportation. Furthermore, there is no need to worry about the lock 2 handle bumping into the door when passing through it. Additionally, since the surface of the entrance door remains flat after the lock 2 is installed, the problem of protruding locks in traditional entrance doors is solved. Thus, the lock 2 can be installed during the door manufacturing process, eliminating the need for users to add it later. This not only simplifies the installation and construction of the entrance door but also allows the lock 2 to be integrated into the door design, resulting in a more cohesive visual effect.
[0044] In practical use, when a user needs to enter the house from the outside, they can perform fingerprint recognition on the fingerprint sensor 212. After successful recognition, the fingerprint sensor 212 sends an unlocking signal to the electric lock body 23, which unlocks according to the unlocking signal, allowing the user to open the entrance door and enter the house. When a user needs to leave the house from the outside, they only need to press the button 223, which sends an unlocking signal to the electric lock body 23, which unlocks according to the unlocking signal, allowing the user to open the entrance door and leave the house. The electric lock body 23 is existing technology and can be purchased from the market. Its specific structure is not within the protection scope of this utility model.
[0045] Furthermore, such as Figure 6 As shown, the door body 1 includes a door frame 12, and the top and bottom ends of the handle assembly 11 are fixedly connected to the top and bottom of the door frame 12, respectively.
[0046] With this design, the handle assembly 11 and the door frame 12 can form a whole. During the process of pushing and pulling the handle assembly 11, the force can be directly transmitted to the door frame 12 through the handle assembly 11. In the long-term use, the handle is not easy to deform, and the handle assembly 11 runs through the entire door body 1 from top to bottom, which also has a better visual effect.
[0047] Furthermore, such as Figure 1 , Figure 2 and Figure 6 As shown, the door body 1 also includes a first front trim panel 13, a second front trim panel 14, and a rear trim panel 15. The handle assembly 11 divides the outdoor side of the door frame 12 into two parts. The first front trim panel 13 and the second front trim panel 14 are respectively installed on the outdoor side of the door frame 12, and the first front trim panel 13 and the second front trim panel 14 are respectively located on both sides of the handle assembly 11. The rear trim panel 15 is installed on the indoor side of the door frame 12.
[0048] With this arrangement, the door 1 can be decorated by using different first front trim panels 13, second front trim panels 14 and rear trim panels 15, thereby making the style of the door 1 more diverse.
[0049] Furthermore, such as Figure 3 and Figure 6 As shown, the rear trim panel 15 has a clearance hole 151, and the handle box 221 is installed in the clearance hole 151.
[0050] By setting the handle hole 2221, it can make way so that the handle box 221 can be embedded and installed into the door body 1.
[0051] Furthermore, such as Figure 5 As shown, one end of the rear handle panel 222 is fastened to the handle box 221, and the other end is screwed to the door frame 12. The rear handle panel 222 and the handle box 221 are respectively clamped to both sides of the rear trim panel 15.
[0052] With this setting, both ends of the back handle panel 222 can be fixed respectively, so that the back handle panel 222 is completely fixed to the surface of the door body 1. During the long-term pushing and pulling of the back handle panel 222, the back handle panel 222 is not easy to loosen, and the structure is more solid.
[0053] Furthermore, such as Figure 4As shown, the handle assembly 11 includes a first handle 111, a second handle 112, and a decorative panel 113. The top and bottom ends of the first handle 111 are fixedly connected to the top and bottom of the door frame 12, respectively, and the first handle 111 has a first slot 1111. The top and bottom ends of the second handle 112 are fixedly connected to the top and bottom of the door frame 12, respectively, and the second handle 112 has a second slot 1121. The first slot 1111 and the second slot 1121 are arranged opposite to each other. The decorative panel 113 is disposed between the first handle 111 and the second handle 112, and both sides of the decorative panel 113 are inserted into the first slot 1111 and the second slot 1121, respectively.
[0054] The handle assembly 11, by setting a first handle 111 and a second handle 112, provides users with more positions for sliding doors. Regardless of whether the user uses their left or right hand, they can conveniently operate the entrance door through the first handle 111 or the second handle 112. A decorative panel 113 is installed between the first handle 111 and the second handle 112, which can connect the first handle 111 and the second handle 112 and also decorate the area between the first handle 111 and the second handle 112. The two sides of the decorative panel 113 are respectively inserted into the first slot 1111 and the second slot 1121. Therefore, the decorative panel 113 and the first handle 111 and the second handle 112 are separate structures. Different patterns, colors and materials of the decorative panel 113 can be selected according to different design effects to adapt to the overall design of the entrance.
[0055] Furthermore, the first handle 111 is provided with a first handle groove 1112, and the second handle 112 is provided with a second handle groove 1122. The first handle groove 1112 and the second handle groove 1122 are arranged opposite to each other. The two ends of the mounting base 213 are respectively inserted into the first handle groove 1112 and the second handle groove 1122, and are fixedly connected to the first handle 111 and the second handle 112.
[0056] With this design, the two ends of the mounting base 213 can be restricted between the first handle groove 1112 and the second handle groove 1122 respectively, and the mounting base 213 can be more firmly installed on the handle assembly 11. In addition, the front handle panel 211 is fixed to the mounting base 213, and its installation structure is also more secure. When the front handle panel 211 is pulled to open or close the door, the front handle panel 211 is not easy to loosen.
[0057] Furthermore, the first handle 111 is provided with a first LED light groove 1113, and the second handle 112 is provided with a second LED light groove 1123. LED light strips 114 are respectively provided in the first LED light groove 1113 and the second LED light groove 1123.
[0058] This design illuminates the area between the first handle 111 and the second handle 112, making it easier to see when opening the door at night. In addition, the LED light strip 114 also has a decorative function to enhance the visual effect of the entrance door.
[0059] Furthermore, such as Figure 3 As shown, the door body 1 also includes an aluminum honeycomb panel 16, which is fixed to the door frame 12 and located between the rear trim panel 15 and the first front trim panel 13 and the second front trim panel 14.
[0060] By installing aluminum honeycomb panels 16 inside the door body 1, the door body 1 can have a better heat insulation effect, making it less likely for heat exchange to occur between the indoor and outdoor areas, and thus achieving better energy-saving effects when cooling or heating indoors.
[0061] Furthermore, the door frame 12 is a thermally broken aluminum structure.
[0062] Door frames 12 are typically assembled from aluminum alloy profiles. Because aluminum alloy is a metal, it conducts heat relatively quickly. Therefore, when there is a significant temperature difference between indoors and outdoors, the aluminum alloy can act as a "bridge" for heat transfer, resulting in poor thermal insulation performance. However, thermally broken aluminum frames break the aluminum alloy in the middle and use rigid plastic to connect the broken sections. Plastic conducts heat much less effectively than metal, making it harder for heat to pass through the entire material, thus improving the thermal insulation performance of the door frame 12.
