[0002] Smart doorbells have become an important component of smart home security systems, widely used in residential and commercial buildings. With increasing market demand, the installation method, mounting structure, and easy disassembly design of smart doorbells have become key factors influencing user experience.

[0003] like Figure 1 As shown, the smart doorbell includes a mounting bracket 101, a doorbell back cover 102, a movable component 103, a spring 104, a cover plate 105, and screws 106. The mounting bracket 101 has clips 107 and 108 at its upper and lower ends, respectively. The doorbell back cover 102 has a slot 109 at its upper end and an opening 110 at its lower end. The movable component 103 extends through the opening 110. The movable component 103 has a movable latch 111. During installation, the spring 104 is assembled onto the movable component 103, and then together they are assembled into the corresponding slot in the doorbell back cover 102. Then, the cover plate 105 is secured to the doorbell back cover 102 using screws 106, fixing the spring 104 within the corresponding cavity of the doorbell back cover 102. At this point, the movable component 103 can only slide up and down within the cavity. Due to the spring's properties, the spring 104 remains at its lowest position when not under pressure, only moving upwards when compressed upwards.

[0004] When the doorbell host needs to be installed on the mounting bracket, first fasten the corresponding buckle 107 in the slot 109, then push the doorbell back cover 102 upward. The movable buckle 111 will generate an upward force when it receives the push, which will cause the movable part 103 to move upward. When the opening 110 is engaged with the movable part 103, the movable part 103 will be lowered by the elastic force of the spring 104, which will lock the buckle 108 in the opening 110. At this time, the doorbell host is fixed on the mounting bracket at both the top and bottom.

[0005] When the doorbell host needs to be disassembled, use the card ejector to push the movable part 103 upward from below, and at the same time pull the buckle 107 out of the doorbell back cover 102 from below. After releasing the card ejector, the movable part 103 returns to its initial position. Then, remove the buckle 108 downward from the opening 110. At this time, the doorbell host is removed from the mounting bracket at both the top and bottom.

[0006] The aforementioned doorbell fixing and disassembly structure requires multiple fixing components such as moving parts, springs, cover plates, and screws. The materials involved are complex, the assembly is difficult, and it increases the production cost of the smart doorbell, thereby affecting the product's market competitiveness.
