[0042] Some embodiments of the antenna assembly of the smart home device and the smart home device provided by the present application are provided below in combination with the accompanying drawings.

[0043] In the following embodiments, the antenna assembly of the smart home device is referred to as an antenna assembly for convenience of description.

[0044] In the embodiments of the first aspect of the present application, an antenna assembly 100 is provided, as shown in Figure 1 , Figure 2 The antenna assembly 100 includes a substrate 1, a radiation part 11, a grounding part 12, an electrical connection part 13 and components 14 arranged on the substrate 1. Figure 1 The mounting base surface of the substrate 1 in the present application is taken as a reference, and the direction of the mounting base surface is a first direction. The radiation part 11 and the grounding part 12 can be located on the same side of the substrate 1 or on opposite sides in the first direction. In the direction parallel to the mounting base surface, the radiation part 11 is located on one side of the grounding part 12, and there is a gap between the grounding part 12 and the radiation part 11, and the electrical connection part 13 and at least one component 14 are arranged on the other side of the grounding part 12. When applied to the smart home device, the electrical connection part 13 is used to electrically connect the components 14 and the grounding part 12 with the control mainboard of the smart home device, the radiation part 11 is used to receive the electrical signal of the control mainboard and convert it into a radio wave and send it outwards, and the radiation part 11 can also receive the radio wave and convert it into an electrical signal and send it to the control mainboard, thereby realizing the conversion and transceiving between the external radio wave and the electrical signal.

[0045] The radiation part 11 is provided with a feed point, one end of the feed point is connected with a feed line, the other end of the feed line is connected with a control mainboard, and the radiation part 11 receives an electric signal from the control mainboard or generates an electric signal to the control mainboard through the feed line. The types of the components 14 can be one or more, and each type of the components 14 can be provided with one or more. In addition, the source of the radio wave can be a handheld device (such as a mobile phone, a handheld computer, a remote controller), and the smart home device can be a smart lock or other home products that can be controlled intelligently.

[0046] It can be understood that the radiation part 11 is a component for transceiving and converting signals in the antenna, and needs to meet certain clearance requirements and maintain a certain interference-free area nearby. However, in the existing smart home products, various components need to be equipped with corresponding circuit boards (such as key small plates, lamp small plates, etc.) to realize corresponding control operations, which is easy to interfere with the performance of the antenna.

[0047] The antenna assembly 100 in the embodiment improves and optimizes the structure, sets a gap between the grounding part 12 and the radiation part 11, and respectively sets the components 14 and the radiation part 11 on both sides of the grounding part 12, and the components 14 are directly connected to the substrate 1. When applied to a smart lock device, the components 14 can be electrically connected to the control mainboard through the electrical connection part 13, and the small plates matched with the components 14 in the prior art are cancelled, which can effectively reduce the interference with the antenna, enhance the accuracy and precision of the control operation of the smart lock device, save space, reduce the complexity of the internal structure, and simplify the assembly operation.

[0048] It should be noted that the substrate 1 and the radiation part 11 and the grounding part 12 in the present application are not limited to the circular ring structure shown in the drawings, and can be set to other shapes according to the use needs.

[0049] In further embodiments of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the number of components 14 is at least two, wherein according to the specific shape of the substrate 1, at least a part of the components 14 can be symmetrically arranged (such as angularly symmetrically arranged or axially symmetrically arranged) on the substrate 1, or uniformly arranged along the other side of the radiation part 11 away from the grounding part 12. Figure 2 and Figure 3For example, the substrate 1 is in a ring structure, the ground part 12 and the radiation part 11 also adopt a ring structure corresponding to the substrate 1, and a part of the components 14 are uniformly arranged along the circumferential direction of the ground part 12, so that the impedance of the antenna assembly 100 is uniform (that is, the input impedance of the antenna assembly 100 remains relatively constant within its working frequency range, and the impedance does not fluctuate significantly with the change of frequency), thereby reducing interference and noise during signal transmission, making the signal more stable and reliable, and reducing the interference of the components 14 on the radiation part 11. In addition, when the substrate 1 adopts other shapes, for example, a square structure, the shapes of the ground part 12 and the radiation part 11 correspond to the substrate 1, and at least a part of the components 14 can be arranged symmetrically, for example, angularly symmetrically, which can also reduce the interference on the radiation part 11.

[0050] In further embodiments of the present application, as in the examples of Figure 2 , Figure 3 and Figure 4 , the components 14 are divided into multiple different types, which specifically include switching devices 141, light-emitting elements 142, and magnetic induction devices 143. When applied to smart home devices, the switching devices 141 can be in contact with the pressing assembly of the smart home device when the pressing assembly is pressed, and generate a corresponding contact signal, which can be received by the control motherboard and perform corresponding control operations; the light-emitting elements 142 can emit light according to the control operation of the control motherboard, thereby displaying the state of the smart home device, such as the on-off state of a smart lock; the magnetic induction devices 143 can sense the magnetic field intensity data in the surrounding environment, thereby detecting the state of the smart home device, for example, in a smart lock, the magnetic field intensity data of a magnet arranged on the door frame is detected by the magnetic induction device 143, thereby detecting the on-off state of the door on which the smart lock is installed. Specifically, the switching devices 141 can adopt micro switches or contact switches; the magnetic induction devices 143 can adopt magnetometer sensors, fluxgate sensors, or Hall sensors.

[0051] Further, as in the examples of Figure 3 and Figure 4 , the light-emitting elements 142 are specifically LED chips that emit light in the powered state. The LED chip as the light-emitting element 142 can effectively save energy and space. When applied to smart home devices, the control motherboard can control the light-emitting state of the LED chip according to the contact signal, for example, the LED chip can be set to a normally closed state and in a non-light-emitting state, and the LED chip is powered to emit light upon receiving the contact signal. Of course, the opposite setting method can also be used, that is, the LED chip is in a light-emitting state, and the LED chip stops emitting light upon receiving the contact signal. The specific use needs can be set, and this will not be described here.

[0052] It should be noted that in actual application, at least one of the above switch device 141, light emitting element 142 and magnetic induction device 143 can be arranged.

[0053] In further embodiments of the present application, as shown in the examples of Figure 2 and Figure 3 , the electrical connection part 13 includes a plurality of independent connection lines 131, which can include power lines, signal lines, control lines and ground lines, the grounding part 12 and the component 14 are respectively connected to the corresponding connection lines 131 to realize electrical connection through the connection lines 131. Specifically, the grounding part 12 is connected to the ground of the control main board by connecting to the ground line, and different pins of the component 14 are connected to the power supply, the control pin of the main control chip and the ground of the control main board by connecting to the corresponding power lines, control lines and ground lines; preferably, the connection lines 131 can be in the form of printed lines to form a printed circuit. In addition, it should be noted that the corresponding connection lines 131 can also be arranged near the outer circle of the grounding part 12 away from the radiation part 11 (for example, as shown in the grounding part 12 in Figure 3 ) to connect the corresponding components 14 to form electrical connection between the components 14, and the specific wiring mode can be set according to actual needs.

[0054] In further embodiments of the present application, as shown in the examples of Figures 1 to 4 , the substrate 1, the radiation part 11, the grounding part 12 and the electrical connection part 13 are all made of flexible materials to form a flexible circuit structure. Optionally, the substrate 1 can be made of insulating flexible materials such as PET (Polyethylene Terephthalate) or PI (Polyimide), and the radiation part 11, the grounding part 12 and the electrical connection part 13 can be made of metal conductive materials (such as copper foil). Since the flexible materials can be bent and folded, they can more easily adapt to the internal structure of various complex smart home devices to facilitate installation in smart home devices. For example Figure 2 , the electrical connection part 13 is provided with a plurality of connection lines 131 (such as printed lines) with relatively long lengths, and the substrate 1 is also provided with corresponding connection lines 131, which can be bent and arranged to facilitate connection with the control main board when applied to smart home.

[0055] In further embodiments of the present application, as shown in the examples of Figures 1 to 4 , the radiation part 11 is electrically connected to the grounding part 12 to ground the radiation part 11, which can effectively shield electromagnetic interference of the radiation part 11 and ensure the continuity of impedance to improve the performance of the antenna assembly. For example Figure 1For example, as shown in FIG. 1, the radiation part 11 and the grounding part 12 are both annular structures, and the radiation part 11 is located radially inside the grounding part 12. A small connecting section can be arranged in the gap between the radiation part 11 and the grounding part 12 to facilitate wiring.

[0056] In further embodiments of the present application, as shown in FIG. 2, the substrate 1, the radiation part 11 and the grounding part 12 are all annular structures, and the radiation part 11 and the grounding part 12 are coaxially arranged on the substrate 1, so that the gap size between the radiation part 11 and the grounding part 12 at any position in the circumferential direction remains consistent, which is conducive to further reducing interference with the radiation part 11. Preferably, the substrate 1, the radiation part 11 and the grounding part 12 are coaxially arranged, which can facilitate assembly and connection with the internal structure of the smart home device, while maintaining a certain distance between the radiation part 11 and other internal structures, thereby further reducing interference with the radiation part 11. Figures 1 to 4 Further, in a specific implementation, as shown in FIG. 3, the radiation part 11 is located radially inside the grounding part 12, and the components 14 and the electrical connection part 13 are located on the other side away from the radiation part 11 in the radial direction, i.e., the radiation part 11 and the grounding part 12 form a concentric circle, and the outer diameter size of the radiation part 11 is smaller than the inner diameter size of the grounding part 12, so as to maintain a radial gap therebetween; at any position in the circumferential direction, the components 14 are located on both sides of the radiation part 11 with respect to the grounding part 12, so as to prevent the components 14 and the electrical connection part 13 on the outer side from interfering with the radiation part 11, which is conducive to maintaining the clearance requirement of the radiation part 11.

[0057] Figure 1 Further, in a specific implementation, as shown in FIG. 3, the radiation part 11 is located radially inside the grounding part 12, and the components 14 and the electrical connection part 13 are located on the other side away from the radiation part 11 in the radial direction, i.e., the radiation part 11 and the grounding part 12 form a concentric circle, and the outer diameter size of the radiation part 11 is smaller than the inner diameter size of the grounding part 12, so as to maintain a radial gap therebetween; at any position in the circumferential direction, the components 14 are located on both sides of the radiation part 11 with respect to the grounding part 12, so as to prevent the components 14 and the electrical connection part 13 on the outer side from interfering with the radiation part 11, which is conducive to maintaining the clearance requirement of the radiation part 11.

[0058] Further, in a specific implementation, as shown in FIG. 3, the radiation part 11 is located radially inside the grounding part 12, and the components 14 and the electrical connection part 13 are located on the other side away from the radiation part 11 in the radial direction, i.e., the radiation part 11 and the grounding part 12 form a concentric circle, and the outer diameter size of the radiation part 11 is smaller than the inner diameter size of the grounding part 12, so as to maintain a radial gap therebetween; at any position in the circumferential direction, the components 14 are located on both sides of the radiation part 11 with respect to the grounding part 12, so as to prevent the components 14 and the electrical connection part 13 on the outer side from interfering with the radiation part 11, which is conducive to maintaining the clearance requirement of the radiation part 11. Figures 2 to 4 Figure 3 Further, in a specific implementation, as shown in FIG. 3, the radiation part 11 is located radially inside the grounding part 12, and the components 14 and the electrical connection part 13 are located on the other side away from the radiation part 11 in the radial direction, i.e., the radiation part 11 and the grounding part 12 form a concentric circle, and the outer diameter size of the radiation part 11 is smaller than the inner diameter size of the grounding part 12, so as to maintain a radial gap therebetween; at any position in the circumferential direction, the components 14 are located on both sides of the radiation part 11 with respect to the grounding part 12, so as to prevent the components 14 and the electrical connection part 13 on the outer side from interfering with the radiation part 11, which is conducive to maintaining the clearance requirement of the radiation part 11.

Wherein, the elastic reset member 28 is arranged between the pressing assembly 27 and the transmission mechanism 24, and in the first direction, one end of the elastic reset member 28 is connected or abuts with the transmission mechanism 24, and the other end is connected or abuts with the pressing assembly 27; when the pressing assembly 27 moves in the direction of approaching the switching assembly under the action of the external force, the elastic reset member 28 is compressed and generates elastic potential energy, and when the external force is removed, the elastic reset member 28 pushes the pressing assembly 27 to move reversely by the elastic force to restore to the original state. Wherein, the elastic reset member 28 can specifically adopt a spring or other elastic structure.

Among them, in the initial state, the contact piece 272 and the switch device 141 have a certain gap in the first direction. The transmission mechanism 24 includes a nested outer sleeve 242 and an inner sleeve 241, the locking claw mechanism 22 is located in the inner sleeve 241 and is fixedly connected with the inner sleeve 241, and the end of the inner sleeve 241 facing the second assembly opening is fixedly connected with the outer sleeve 242; the outer side wall of the outer sleeve 242 is provided with a toothed structure and is engaged with the gear of the output end of the driving mechanism 23 to form a gear mechanism 243; the driving mechanism 23 is electrically connected with the power supply assembly 29 and the control mainboard 25 to control the driving mechanism 23 through the control mainboard 25.

[0071] As shown in the initial state, Figures 8 to 12 When the pressing piece 271 is pressed, the pressing piece 271 moves in the first direction and forms extrusion to the contact piece 272, and then drives the contact piece 272 to move in the first direction towards the switch device 141, and then contacts with the switch device 141 to make the switch device 141 generate a contact signal, and the control mainboard 25 receives the contact signal and controls the driving mechanism 23 to work, and drives the locking claw mechanism 22 to rotate through the transmission mechanism 24 to drive the knob of the door lock to rotate, so as to realize the unlocking or locking.
