[0026] refer to Figure 1 In one embodiment, a doorbell assembly 10 is provided. The doorbell assembly 10 is installed on the door and is a button 500 doorbell with a waterproof function. When rain hits the door in windy and rainy weather, the rain easily penetrates into 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.

[0027] refer to Figure 2 and Figure 3In 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 110, and the seal 200 is received in the receiving groove 110 and connected to the housing 100. The seal 200 has good waterproof performance and a certain degree of flexible deformation ability. When the seal 200 is connected to the housing 100, one end of the receiving groove 110 can be sealed, that is, the seal 200 can protect one end of the receiving groove 110 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 110 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 110 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.

[0028] refer to Figure 3 In one embodiment, the button 500 is accommodated in the receiving groove 110 and exposed to the housing 100. One end of the button 500 abuts against the seal 200, and the other end abuts against the side of the housing 100 facing the circuit board 400. The button 500 can trigger the electric control unit 410 through the seal 200. Further, the material of the button 500 can be a component with a certain degree of hardness such as plastic. When the user presses the button 500, the seal 200 is squeezed and deformed, and the seal 200 can be deformed to contact the electric control unit 410, so that the electric control unit 410 is triggered to ring. After pressing the button 500, the reset 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 when the button 500 is in a natural state, the button 500 abuts against one side of the housing 100 to prevent the button 500 from escaping from the receiving groove 110, that is, to prevent the button 500 from loosening.

[0029] The doorbell assembly 10 comprises a housing 120, a shell 100, a circuit board 400, a seal 200 and a button 500. The button 500 is accommodated in the accommodating groove 110 and exposed from the shell 100. One end of the button 500 abuts against the seal 200, and the other end abuts against the side of the shell 100 facing the circuit board 400, and the electric control unit 410 is triggered by the seal 200. The seal 200 of the doorbell assembly 10 is accommodated in the accommodating groove 110 and abuts against the shell 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.

[0030] refer to Figure 3 In one embodiment, the housing 100 includes a shell 120 and a panel 130 connected to the shell 120. The shell 120 and the panel 130 may be detachable structures to facilitate replacement and installation of the doorbell assembly 10. The seal 200 is connected to the panel 130. The shell 120 is located on the side of the panel 130 facing away from the circuit board 400. The button 500 abuts against the side of the shell 120 facing the panel 130. Specifically, the size of the notch of the receiving groove 110 located at the shell 120 is smaller than the size of the notch of the receiving groove 110 located at the panel 130. One end of the button 500 can pass through the notch of the shell 120, and the other end can abut against the side of the shell 120 facing the panel 130 to prevent the button 500 from sliding out of the receiving groove 110. It can be understood that the shell 120 and the panel 130 can also be integrally formed.

[0031] In one embodiment, the pressing plate 300 is fixed to the panel 130 by ultrasonic welding. Further, the pressing plate 300 is connected to the panel 130 and presses the sealing member 200, that is, the pressing plate 300 can first press the sealing member 200, and then the pressing plate 300 and the panel 130 are welded together by ultrasonic welding process. At this time, the pressing plate 300 and the panel 130 cannot be separated, and the pressure of the pressing plate 300 pressing the sealing member 200 is large and uniform, and the sealing effect of the sealing member 200 is enhanced, preventing water from entering the circuit board 400. In other embodiments, a pressing cavity can be preset before the pressing plate 300 and the panel 130 are fused. When the pressing plate 300 presses the sealing member 200, it can prevent the sealing member 200 from being squeezed out in 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.

[0032] refer to Figure 3In one embodiment, the sealing member 200 includes a body 210 and a connecting portion 220 connected to the body 210, the button 500 is supported by the body 210 and can be exposed to the housing 120, and the connecting portion 220 is connected to the panel 130. Specifically, the sealing member 200 can be a disk-like structure, that is, the body 210 can be a disk-like structure, and the connecting portion 220 is arranged around the body 210, that is, the connecting portion 220 is connected to the circumferential edge of the body 210 and is annular. Since the connecting portion 220 is connected to the housing 100 and can form a sealed cavity, the groove wall of the accommodating groove 110 located in the housing 120 can be a ring-like structure, so that the connecting member is connected to the groove wall of the accommodating groove 110, that is, connected to the panel 130. In one embodiment, a limiting groove 221 is provided on the side of the connection part 220 facing away from the circuit board 400, and the housing 100 protrudes toward the side where the circuit board 400 is located to form a limiting part 131, and the limiting part 131 can be exactly accommodated in the limiting groove 221. When the connection part 220 is annular, the limiting groove 221 is an annular groove, and the limiting part 131 and the limiting groove 221 are adapted to each other, that is, the shape of the limiting part 131 can also be annular, and the limiting part 131 is accommodated in the limiting groove 221. Even if water flows in along the gap between the housing 120 and the button 500, due to the obstruction of the sealing member 200, the water flowing in will accumulate in the limiting groove 221, and will not flow into the sealed cavity and damage the circuit board 400. This arrangement enhances the waterproof performance.

[0033] 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 the connection portion 220. Specifically, the pressing plate 300 presses 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 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 and the panel 130 are fused by ultrasonic wave, the supporting portion 310 presses the connection portion 220, and the pressing force is uniform. 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 from the opening of the recessed area 223 to be flush with or protrude from the opening to facilitate the fusion of the panel 130.

[0034] Furthermore, since the connection between the pressing plate 300 and the panel 130 is through a fusion process, the panel 130 can be preset with sufficient space, so that when the pressing plate 300 is fused to the panel 130, 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, so as 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 shell can be thinner, and further the thickness of the shell can be 4 mm or more, so that the thickness of the shell is as thin as possible.

[0035] refer to Figure 3 In one embodiment, a fixing portion 211 is provided on the side of the body 210 facing the circuit board 400, that is, the fixing portion 211 is located in the sealed cavity surrounded by the seal 200, the fixing portion 211 abuts against the circuit board 400 and forms a closed cavity 215 with the circuit board 400, and the electric control unit 410 is located in the cavity 215. Further, the fixing portion 211 can be annular, the annular fixing portion 211 contacts the circuit board 400, and the electric control unit 410 is enclosed in the cavity 215, further enhancing the waterproof performance of the doorbell assembly 10, and at the same time, because the material of the fixing portion 211 can also be silicone, when the button 500 presses the seal 200, the fixing portion 211 is squeezed and deformed, so that the body 210 can trigger the electric control unit 410, and the user's hand feeling of pressing the button is stronger. After triggering, the fixing portion 211 resets and rebounds. In another embodiment, the fixing portion 211 may also be in a strip shape. When the fixing portion 211 is in a strip shape, a plurality of fixing columns may be provided. The plurality of fixing columns are spaced to form a cavity 215 and abut against the circuit board 400, and the electrical control unit 410 is enclosed in the cavity 215. When the user presses the sealing member 200, the plurality of fixing portions 211 also enhance the user's hand feeling.

[0036] In one embodiment, a touch slot 213 is provided on one 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 213, and the bottom of the touch slot 213 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 213. When the user presses the button 500, the button 500 abuts against the bottom of the touch slot 213 and squeezes the body 210. The body 210 squeezes the fixing portion 211 to deform the fixing portion 211, thereby causing the body 210 to trigger the electric control unit 410 to ring. In one embodiment, the button 500 includes a touch portion 510 and a pressing portion 520 connected to the touch portion 510. The touch portion 510 is accommodated in the touch slot 213, and the pressing portion 520 is exposed from the housing 120. Among them, the touch groove 213 assembles and positions the touch part 510, the pressing part 520 is exposed from the shell 120, and the shape of the cross section of the pressing part 520 can be circular, square, rectangular, prismatic, etc. When the cross section of the pressing part 520 is circular, the diameter of the pressing part 520 can be greater than 25 mm, and the circumferential edge of the pressing part 520 abuts against the side of the shell 120 facing the circuit board 400 to prevent the button 500 from falling out.

[0037] refer to Figure 3 In one embodiment, a protrusion 521 is provided on the circumference of the pressing portion 520, and the protrusion 521 is accommodated in the accommodating groove 110 and abuts against the side of the housing 120 facing the circuit board 400. Specifically, a protrusion 521 is provided at the circumferential edge of the pressing portion 520, and at least four protrusions 521 are provided. The four protrusions 521 can be arranged at equal intervals on the circumference of the pressing portion 520, so that the button remains balanced. The touch portion 510 located in the touch groove 213 is the force application point for triggering the electric control component. When the user presses 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 protrusion 521 of the button 500 opposite to the pressing position can be used as a fulcrum of a lever, and the lever principle can be used to make the touch portion 510 produce an inward displacement, thereby triggering the electric control component 410 through the sealing member 200. Similarly, using the principle of lever, when the user presses other positions on the surface of the pressing portion 520, the touch portion 510 can be squeezed, so that the touch portion 510 squeezes the seal 200, and the seal 200 is deformed and triggers the electric control unit 410. It is understandable that the shape of the protrusion 521 can also be similar to a ring, and the ring-shaped protrusion 521 surrounds the circumferential edge of the pressing portion 520, and the protrusion 521 is against the side of the housing 120 facing the circuit board 400. The setting of the above-mentioned protrusion 521 can prevent the button 500 from escaping from the accommodating groove 110, play the role of assembly limit, and effectively improve the assembly efficiency. Among them, the area of ​​the pressing portion 520 of the button 500 can also be slightly larger, and a group is carved on the surface of the pressing portion 520 to increase the user's interest.

[0038] 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. The light emitting member 600 may be an LED lamp, and the circuit board 400 may cause the LED lamp to emit light. In one embodiment, at least part of the structure of the seal 200 and the button 500 is light-transmissive, so that the light emitted by the light emitting member 600 can be observed from the exposed surface of the button 500. Specifically, the seal 200 and the button 500 may be made of a light-transmissive material, for example, with a light transmittance of more than 60%. When the LED lamp emits light, the emitted light passes through the seal 200 and is exposed from the surface of the button 500. Alternatively, the seal 200 may be made of a transparent silicone material, and the button 500 may be made of a light-transmissive material, so that the light of the LED lamp can still be observed from the surface of the button 500, so that the doorbell assembly 10 is given a luster, thereby enhancing the decorative effect of the doorbell assembly 10. A pattern may be provided on the surface of the button 500 so that when the light-emitting element 600 is exposed on the surface of the button 500, the pattern emits light, thereby increasing the interest of the doorbell assembly 10. In particular, in a dark environment such as at night, the provision of the light-emitting element 600 allows the user to more easily observe the position of the doorbell assembly 10, thereby improving the convenience of use.
