Abstract
Description
Technical Field
[0001] This utility model relates to the field of door technology, and more specifically, to an intelligent system entrance door. Background Technology
[0002] Traditional doors typically consist of a door frame and fixed door panels, with the panels permanently connected to the frame via hinges. This structure has the following drawbacks: limited functionality; if a user needs to change the door panel type (e.g., different colors or styles), the entire door must be removed, leading to cumbersome and costly construction; and maintenance is inconvenient, as replacement of damaged sections requires specialized tools and technicians, resulting in low efficiency. Based on these issues, this application proposes a smart system entrance door that allows for individual and convenient replacement of door panel styles. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent system entrance door that can change the style of the door leaf individually and is easy to replace.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent system entrance door, including a door leaf body, with assembly areas on both the front and rear ends of the door leaf body, a detachable door panel in the assembly area, and a detachable rear cover at the opening of the assembly area, the assembly area including baffles on both sides of the assembly area, slots formed between the baffles and the bottom wall of the assembly area, the two sides of the door panel being inserted into the slots for assembly, and a sealing and waterproof structure at the bottom of the door leaf body.
[0005] The present invention is further configured such that: the sealing and waterproof structure includes two sealing strips with the same structure, and a sealing block is provided between the two sealing strips; the bottom of the door body is provided with an inner groove one for assembling the sealing strips and an inner groove two for assembling the sealing block; the cross-section of the sealing block is larger than the cross-section of the sealing strip.
[0006] The present invention is further configured such that: the sealing strip includes an assembly end and a sealing end, the cross-section of which gradually decreases from the assembly end toward the sealing end; the assembly end is provided with elastic barbs on both sides, which abut against the side wall of the inner groove; and the sealing end extends to the outside of the inner groove.
[0007] The present invention is further configured such that: one end of the cross-section of the sealing block is T-shaped and the other end is semi-circular; a mounting bracket is provided in the inner groove; and a strip groove adapted to the T-shaped block is provided in the mounting bracket.
[0008] By adopting the above technical solutions, the system offers convenient door panel style replacement. Users can easily change door panels without specialized tools or technical assistance, greatly simplifying the replacement process, reducing costs, and meeting diverse user needs for personalized door panel styles, thus enhancing the user experience. It also boasts efficient maintenance; when a part of the door panel is damaged, users can quickly disassemble and replace the damaged section without complex disassembly and reassembly of the entire door, saving maintenance time and costs, increasing the door's lifespan and reliability, and reducing safety hazards caused by untimely maintenance. Furthermore, it enhances the user experience, allowing users to change door panel styles at any time according to their preferences and needs without worrying about complex construction and high costs. Simultaneously, the convenient maintenance reduces user concerns during use, making the entrance door more convenient and reliable, greatly improving user satisfaction and comfort.

Detailed Implementation
[0014] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.
[0015] A smart system entrance door includes a door leaf body 1. The front and rear ends of the door leaf body 1 are provided with assembly areas 10. The assembly areas 10 are provided with detachable door panels 2 and detachable rear covers 4 located at the opening of the assembly areas 10. The assembly areas 10 include baffles 11 located on both sides of the assembly areas 10. The baffles 11 and the bottom wall of the assembly areas 10 form slots 12. The two sides of the door panels 2 are inserted into the slots 12 for assembly. The bottom of the door leaf body 1 is provided with a sealing and waterproof structure 3.
[0016] The sealing and waterproof structure 3 includes two identical sealing strips 30, with a sealing block 31 between them. The bottom of the door body 1 has a first inner groove 13 for assembling the sealing strips 30 and a second inner groove 14 for assembling the sealing block 31. The cross-section of the sealing block 31 is larger than that of the sealing strip 30. The sealing strip 30 includes an assembly end 300 and a sealing end 301, with its cross-section gradually decreasing from the assembly end 300 towards the sealing end 301. The assembly end 300 has elastic barbs 302 on both sides that abut against the sidewalls of the first inner groove 13, and the sealing end 301 extends beyond the first inner groove 13. The sealing block 31 has a T-shaped block 310 at one end and a semi-circular block 311 at the other end. The second inner groove 14 contains a mounting bracket 15, which has a strip-shaped groove 16 that fits the T-shaped block 310.
[0017] Working principle: When the door panel 2 needs to be replaced, first remove the rear cover 4, then remove the door panel 2 from the assembly area 10, and then assemble the replacement door panel 2 with the door body 1. During assembly, the door panel 2 is inserted into the opening of the assembly area 10, and its two sides are inserted into the slots 12 for fixing. Then, the rear cover 4 seals the opening of the assembly area 10, which serves to fix the assembled door panel 2.
[0018] Two sealing strips 30 and one sealing block 31 are installed at the bottom of the door body 1. This structure is suitable for entry doors without thresholds. The waterproof structure 3 contacts the ground to achieve three layers of waterproof sealing, which helps to improve the overall sealing performance of the door.
[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
