[0033] refer to Figure 1 In one embodiment, a doorbell assembly 10 is provided. The doorbell assembly 10 is installed on the door, can be a button 500 doorbell and has a waterproof function. When the rain hits the door in windy and rainy weather, the rain easily invades the interior of the doorbell assembly 10, so that the internal parts fail due to contact with water. The waterproof function of the doorbell assembly 10 reduces the risk of failure of the button 500 of the doorbell assembly 10 and improves its reliability. Of course, the doorbell assembly 10 can also prevent the sweat on the user's hands or other liquids in the use environment from entering the doorbell assembly 10 through the gap at the button 500, so as to achieve a better waterproof and dustproof effect.

[0034] refer to Figure 2 and Figure 3 In one embodiment, the doorbell assembly 10 includes a housing 100, a seal 200, a pressure plate 300, a circuit board 400 and a button 500. The housing 100 is provided with a receiving groove 121, and the seal 200 is received in the receiving groove 121 and connected to the housing 100. Among them, the seal 200 has good waterproof performance and also has a certain flexible deformation ability. When the seal 200 is connected to the housing 100, one end of the receiving groove 121 can be sealed, that is, the seal 200 can protect one end of the receiving groove 121 from water. For example, the seal 200 can be silicone, and silicone also has a certain resilience. In one embodiment, the pressure plate 300 is connected to the housing 100 to press the seal 200, so that the connection between the seal 200 and the housing 100 is more firm, further preventing the intrusion of water flow. In one embodiment, the circuit board 400 is disposed on a side of the sealing member 200 away from the receiving groove 121 and connected to the housing 100. The housing 100 and the circuit board 400 can be connected by threads, and the circuit board 400 is provided with an electric control unit 410. Specifically, the sealing member 200 can divide the receiving groove 121 into two groove bodies, the two groove bodies are arranged opposite to each other, one of the groove bodies is connected to the outside, and the other groove body is opposite to the groove body and can form a sealed cavity with the housing 100 and the circuit board 400. The electric control unit 410 is accommodated in the cavity, which effectively improves the waterproof sealing effect of the electric control unit 410.

[0035] In one embodiment, the button 500 is accommodated in the accommodating groove 121 and is clamped on the housing 100. Part of the structure of the button 500 abuts against the sealing member 200 to trigger the electronic control unit 410 through the sealing member 200. Furthermore, the material of the button 500 can be plastic or other materials with certain hardWhen the user presses the button 500, the button 500 presses against the part of the seal 200 to squeeze the seal 200, so that the seal 200 is squeezed and then touches the electric control unit 410, and the ringing is completed. After pressing the button 500, the resetting elastic force of the seal 200 can drive the button 500 to automatically reset, thereby improving the reliability of the button 500. It can be understood that in the natural state, the button 500 is clamped on one side of the housing 100 to prevent the button 500 from being separated from the receiving groove 121, that is, to prevent the button 500 from being loose.

[0036] The doorbell assembly 10 comprises a housing 100, a seal 200, a pressure plate 300, a circuit board 400 and a button 500. The button 500 is accommodated in the accommodating groove 121 and exposed from the housing 100. One end of the button 500 abuts against the seal 200, and the other end clamps the housing 100, and triggers the electric control unit 410 through the seal 200. The seal 200 of the doorbell assembly 10 is accommodated in the accommodating groove 121 and connected to the housing 100, and forms a sealed cavity with the circuit board 400. The electric control unit 410 is located in the sealed cavity, which effectively prevents external water from entering the circuit board 400 to damage the circuit board 400 and the electric control unit 410.

[0037] refer to Figure 4 In one embodiment, the housing 100 includes an outer shell 110 and a light guide 120 connected to the outer shell 110. The outer shell 110 and the light guide 120 can also be integrally formed to achieve a seamless connection, so that the waterproof level can reach IP68. The light guide 120 is recessed to form a receiving groove 121, and the sealing member 200 is connected to the light guide 120. The outer shell 110 is located on the side of the light guide 120 that is away from the receiving groove 121, and is connected to the circuit board 400. Specifically, the light guide 120 can be a ring-like structure, and the outer shell 110 surrounds the outer side of the light guide 120 to enclose the light guide 120, and the end of the outer shell 110 away from the outside is connected to the circuit board 400, and the connection method can be a threaded connection. Combined with Figure 3 The button 500 is accommodated in the receiving groove 121 and abuts against the sealing member 200. Part of the structure of the button 500 is clamped on the light guide 120, and the other part of the structure can pass through the notch of the receiving groove 121 or be flush with the height of the notch, so that when the user presses the button 500, it is easier to contact the button 500, thereby achieving the pressing of the button 500. It can be understood that the housing 110 and the light guide 120 can be detachable structures to facilitate the replacement and installation of the doorbell assembly 10.

[0038] refer to Figure 3 and Figure 5In one embodiment, the seal 200 includes a body 210 and a connecting portion 220 connected to the body 210, the button 500 is abutted against the body 210, the side of the body 210 facing the circuit board 400 abuts against the electric control unit 410, and the connecting portion 220 is connected to the light guide 120. Specifically, when the light guide 120 is annular, the cross-section of the accommodating groove 121 is roughly disc-shaped. Since the seal 200 is accommodated in the accommodating groove 121, that is, the seal 200 can be a disc-like structure, the body 210 can be a disc-like structure. The connecting portion 220 is connected to the body 210, that is, the connecting portion 220 can be arranged around the body 210. It can be understood that the connecting portion 220 is connected to the circumferential edge of the body 210 and is annular. In one embodiment, the connection portion 220 is provided with a protrusion 221, the protrusion 221 protrudes from the side of the connection portion 220 facing away from the circuit board 400, and the light guide 120 is provided with a limiting groove 125 on the side facing the circuit board 400, and the protrusion 221 is accommodated in the limiting groove 125. Further, when the shape of the connection portion 220 is annular, the protrusion 221 is provided on the connection portion 220, and the shape of the protrusion 221 can also be annular and protrude from the connection portion 220, and the protrusion 221 is accommodated in the limiting groove 125, that is, the limiting groove 125 is located on the side of the connection portion 220 facing the circuit board 400, and the protrusion 221 and the limiting groove 125 are adapted to each other, and at this time, the cross section of the limiting groove 125 is annular. Due to the sealing relationship between the protrusion 221 and the limiting groove 125, when water flows in along the gap between the shell 110 and the button 500, the water will accumulate at the body 210 and will not flow into the sealed cavity through the connecting part 220, thereby effectively enhancing the waterproof performance.

[0039] refer to Figure 3 In one embodiment, the connection portion 220 is recessed toward one side of the circuit board 400 to form a recessed area 223, and the recessed area 223 extends to the edge of the connection portion 220. At least part of the structure of the pressing plate 300 is accommodated in the recessed area 223 and presses against the connection portion 220. Specifically, the pressing plate 300 presses against the connection portion 220 through the recessed area 223, wherein the pressing plate 300 includes a supporting portion 310 and a fusion portion 320, and the supporting portion 310 and the fusion portion 320 are integrally formed, and the supporting portion 310 can be accommodated in the recessed area 223 and press against the connection portion 220, and the shape of the supporting portion 310 is adapted to the shape of the recessed area 223. When the fusion portion 320 is connected to the light guide 120, the supporting portion 310 presses the connection portion 220 to achieve a sealed connection. In another embodiment, the pressing plate 300 may not include the abutting portion 310 and the fusion portion 320 , that is, the entire structure of the pressing plate 300 abuts against the recessed area 223 , and one side of the pressing plate 300 protrudes flush with the opening of the recessed area 223 to facilitate fusion of the light guide 120 .

[0040] In one embodiment, the pressing plate 300 is ultrasonically welded to the light guide 120. Specifically, the pressing plate 300 is connected to the light guide 120 and presses against the sealing member 200, that is, the pressing plate 300 can first press against the sealing member 200, and then the pressing plate 300 and the light guide 120 are welded into one body through an ultrasonic welding process. At this time, the pressing plate 300 and the light guide 120 cannot be separated, and the pressure of the pressing plate 300 pressing the sealing member 200 is large and uniform, and at the same time, the sealing effect of the sealing member 200 is enhanced to prevent water from entering the circuit board 400. In other embodiments, a pressing cavity can be preset before the pressing plate 300 and the light guide 120 are fused. When the pressing plate 300 presses the sealing member 200, the sealing member 200 can be prevented from being squeezed out of the pressing cavity due to excessive pressing force. It is understandable that the seal 200 in the pressing cavity can be preset with a larger pre-compression amount, which is set for a high waterproof level, and the IP68 waterproof level can be achieved under the pressing force, thereby obtaining better waterproof and dustproof performance.

[0041] Furthermore, since the connection between the pressing plate 300 and the light guide 120 is through a fusion process, the light guide 120 can be preset with sufficient space, so that when the pressing plate 300 is fused to the light guide 120, there is still a gap, that is, there can be a gap between the pressing plate 300 and the circuit board 400, and then there can also be a gap between the connecting portion 220 and the circuit board 400, to prevent the pressing plate 300 from exerting pressure on the circuit board 400 and damaging the components of the circuit board 400. Among them, the thickness of the pressing plate 300 can be thinner, and then the thickness of the housing 100 can be thinner, and further the thickness of the housing 100 can be 4 mm or more, so that the thickness of the housing 100 is as thin as possible.

[0042] refer to Figure 4 and Figure 5 In one embodiment, a touch slot 211 is provided on the side of the body 210 facing away from the circuit board 400, and a part of the structure of the button 500 is accommodated in the touch slot 211, and the bottom of the touch slot 211 can abut against the body 210 to trigger the electric control unit 410. Part of the structure of the button 500 is adapted to the touch slot 211. When the user presses the button 500, the button 500 abuts against the bottom of the touch slot 211 and squeezes the body 210. The body 210 squeezes the fixed part to deform the fixed part, thereby causing the body 210 to trigger the electric control unit 410 to ring the bell. Figure 7In one embodiment, the button 500 includes a touch portion 510, a clamping portion 520 and a pressing portion 530, wherein the touch portion 510 and the clamping portion 520 are respectively connected to the pressing portion 530 and protrude from the side of the pressing portion 530 facing the circuit board 400, wherein the touch portion 510, the clamping portion 520 and the pressing portion 530 can also be integrally formed. Specifically, the touch portion 510 is accommodated in the touch slot 211 to hold the seal 200 to achieve assembly positioning, the clamping portion 520 is clamped on the light guide 120 to prevent the button 500 from falling out, and the pressing portion 530 is exposed on the light guide 120. Among them, the cross-section of the pressing portion 530 can be a circular, square, rectangular, prismatic or other shapes that are convenient for users to press. When the cross-section of the pressing portion 530 is circular, the diameter of the pressing portion 530 can be greater than 25 mm, and a larger contact area can improve the practical experience of users. It is understandable that the pressing portion 530 may be designed to have a shape in which the middle thickness is smaller than the edge thickness, so that when the user presses the pressing portion 530 , the pressing feeling is more comfortable.

[0043] refer to Figure 3 , Figure 6 and Figure 7 In one embodiment, the holding portion 520 includes a plurality of holding portions 520 which are arranged at intervals around the touch portion 510. Specifically, the holding portion 520 is roughly hook-shaped, and at least four holding portions 520 are arranged at equal intervals around the touch portion 510 to keep the button balanced. The touch portion 510 located in the touch slot 211 is the force application point for triggering the electric control unit 410. In the process of the user pressing the button 500, in extreme cases, such as when the user presses the edge of the button 500, the above-mentioned structure is set so that the holding portion 520 of the button 500 opposite to the pressing position can be used as a fulcrum of the lever, and the touch portion 510 can be displaced inward by using the lever principle, thereby triggering the electric control unit 410 through the sealing member 200. Similarly, by using the lever principle, when the user presses other positions on the surface of the pressing portion 530, the touch portion 510 can be squeezed, so that the touch portion 510 squeezes the sealing member 200, and the sealing member 200 is deformed to trigger the electric control unit 410. It is understandable that the clamping portion 520 may also surround the circumference of the touch portion 510, that is, the clamping portion 520 may also be shaped like a ring and clamped on the light guide 120. Figure 8 , Fig. 9 and Fig.10In one embodiment, the light guide 120 is further provided with a card slot 123, and the card slot 123 extends to the edge of the light guide 120, so that the clamping portion 520 is clamped in the card slot 123. Furthermore, the shape of the card slot 123 can be mutually adapted with the clamping portion 520, so that the clamping portion 520 can be stably clamped on the light guide 120. The setting of the above-mentioned clamping portion 520 can prevent the button 500 from escaping from the accommodating groove 121, play the role of assembly limit, and effectively improve the assembly efficiency. Among them, the area of ​​the pressing portion 530 of the button 500 can also be slightly larger, and a group is engraved on the surface of the pressing portion 530 to increase the interest of the user.

[0044] refer to Figure 3 and Figure 7 In one embodiment, a gap is formed between the clamping portion 520 and the touch portion 510, and part of the structure of the body 210 is accommodated in the gap and the touch portion 510 is sleeved through the touch slot 211. Specifically, when the touch portion 510 is accommodated in the touch slot 211, the groove wall of the touch slot 211 can be accommodated in the gap between the clamping portion 520 and the touch portion 510, and the clamping portion 520 is clamped with the clamping slot 123. The above-mentioned matching relationship is sufficient to make the matching relationship between the key 500 and the sealing member 200 closer, and the waterproof coefficient is also higher.

[0045] refer to Figure 3 In one embodiment, the doorbell assembly 10 further includes a light emitting member 600, which is electrically connected to the circuit board 400, and the light emitted by the light emitting member 600 can be observed from the surface exposed by the light guide 120. Specifically, the light guide 120 can be made of a light-transmitting material, and the light emitting member 600 can be an LED lamp, and is arranged in an array on the circuit board 400. The circuit board 400 can cause the LED lamp to emit light, for example, its light transmittance is above 60%. When the LED lamp emits light, the emitted light reaches the light guide 120 and is exposed from the surface of the light guide 120, so that the doorbell assembly 10 adds a luster. When the surface of the light guide 120 exposed to the outside world is in a ring shape, after the light emitting members 600 arranged in an array emit light, a marquee effect can be achieved on the surface of the light guide 120, thereby enhancing the decorative effect of the doorbell assembly 10. In particular, in a dark environment such as at night, the provision of the light emitting member 600 can make it easier for the user to observe the position of the doorbell assembly 10, so as to improve the convenience of use.
