Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] In small electronic products such as remote controls, the space available for antenna design is limited after deducting the power supply and necessary hardware components. This presents challenges for antenna design in these types of electronic products.

[0035] Battery-powered products, such as remote controls and door magnets, have a wide range of applications and are usually small in size. After removing the battery and necessary hardware, there is little space left for antenna design. In addition, the PCB control board is usually close to the battery. From the perspective of PCB onboard antenna design, the close proximity makes it easy to be affected by the battery, which can affect the antenna performance.

[0036] Under these circumstances, the inventors utilized existing batteries and their metal casings as antenna components to achieve antenna performance. This invention overcomes the antenna design difficulties caused by the small size of existing battery-powered products. By using existing battery components as antenna parts, the battery can both provide power and radiate through the metal casing to achieve antenna functionality.

[0037] Specifically, to address the technical problem of limited product space affecting antenna design in related technologies, in a first aspect, embodiments of this application provide a communication device to achieve antenna performance by using a power supply as an antenna component. The communication device includes an antenna; the antenna includes: a first power supply, one power terminal of which is configured as both a receiving end and a transmitting end of the antenna; and an radio frequency chip for connecting in series with the two power terminals of the first power supply to form a circuit link loop.

[0038] Therefore, in this embodiment of the application, a first power supply, a capacitor, and an RF chip are used to make one power terminal of the first power supply the receiving end and the transmitting end of the antenna. Thus, by using the power supply as an antenna component, antenna performance is achieved, improving or solving the problem of limited product space affecting antenna design in related technologies.

[0039] Specifically, Figure 1 This is a schematic diagram of the circuit principle of a communication device according to one embodiment. (Reference) Figure 1 As shown, in one embodiment of this application, the communication device includes a first radio frequency chip 01, a first power supply a 02, and a ground terminal a 03. The first radio frequency chip 01 is grounded, and the two ends of the first radio frequency chip 01 are connected to the first power supply a 02 to form a circuit link loop. Thus, the first power supply a 02 serves as a power supply on one hand and as the receiving end and transmitting end of the antenna on the other hand, thereby playing the role of an antenna. By using the first power supply a 02 as an antenna component, the space occupied by the antenna can be reduced.

[0040] The antenna's signal source comes from the radio frequency (RF) chip. If the RF chip is directly connected to the battery via a link, the battery voltage can easily damage the RF chip. A capacitor needs to be added to the link to prevent damage to the chip. The capacitor acts as a conductor at high frequencies, which can protect the RF chip without affecting signal transmission.

[0041] Furthermore, the first power source is a first battery, and the antenna includes a capacitor; the radio frequency chip is connected in series with the two power terminals of the first power source through the capacitor to form a circuit link loop.

[0042] Figure 2 This is a schematic diagram of the circuit principle of a communication device according to another embodiment. In another embodiment of this application, the communication device includes a second radio frequency chip 11, a first power supply b 12, and a capacitor a 14; the negative terminal of the first power supply b 12, the second radio frequency chip 11, the capacitor a 14, and the positive terminal of the first power supply b 12 are connected in series to form a circuit link loop; optionally, the second radio frequency chip 11 is grounded through a ground terminal b 13. Optionally, a via a 15 is provided between the capacitor a 14 and the positive terminal of the first power supply b 12.

[0043] In some electronic products, using the first battery as both an antenna and a power source cannot meet the power supply requirements. Therefore, in some electronic products, multiple batteries are often required to meet the power supply needs while fulfilling the antenna function.

[0044] Furthermore, a second power supply is connected in parallel to the two power terminals of the first power supply, and the radio frequency chip is connected in series with the first power supply through the capacitor, and the radio frequency chip is connected in series with the second power supply through the capacitor.

[0045] Figure 3 This is a schematic diagram of the circuit principle of a communication device according to another embodiment. See also... Figure 3 As shown, the communication device includes a third RF chip 21, a first power supply c 22, a capacitor b 24, and a second power supply a 26. The second power supply a 26 is connected in parallel with the first power supply c 22. The third RF chip 21 is connected in series with the parallel power supply (i.e., the power supply after the second power supply a 26 and the first power supply c 22 are connected in parallel) through the capacitor b 24, forming a circuit link loop. Optionally, the communication device also includes a via b 25. Optionally, the positive terminals of the third RF chip 21, capacitor b 24, via b 25, and the first power supply c 22 are connected in series. The positive terminal of the second power supply a 26 is connected to the link between the via b 25 and the positive terminal of the first power supply c 22, and the negative terminal of the second power supply a 26 is connected to the negative terminal of the first power supply c 22. Optionally, the third RF chip 21 is grounded through a ground terminal c 23.

[0046] Furthermore, the second power source is a second battery; the antenna includes a first inductor, the second power source is connected in series with the first inductor and then connected in parallel with the two power terminals of the first power source, and the radio frequency chip is connected in series with the second power source through the capacitor and the first inductor in sequence.

[0047] Following the above embodiment, to ensure the normal operation of the second power supply a 26, an isolation device needs to be added to the link. Optionally, the second power supply a 26 is connected in series with the first inductor a 27, and the second power supply a 26 is connected in parallel with the first power supply c 22 after being connected in series with the first inductor a 27. Using this method, on the one hand, the normal power supply of the second power supply a 26 is ensured. This is because the inductor has the property of blocking high frequencies and passing low frequencies. When the first power supply c 22 is used as an antenna, the first inductor a 27 acts as an open circuit for high frequencies, while for DC circuits, the first inductor a 27 can conduct the circuit, thereby ensuring the normal parallel power supply function of the two batteries (the first battery and the second battery).

[0048] Furthermore, the negative terminal of the first power supply is configured as the receiving and transmitting end of the antenna, and the radio frequency chip is grounded; the antenna also includes a second inductor; one end of the second inductor is grounded, and the other end of the second inductor is connected to the negative terminal of the second power supply through the first inductor; the other end of the second inductor is also connected to the link between the capacitor and the negative terminal of the first power supply.

[0049] Figure 4 This is a circuit diagram of a communication device according to yet another embodiment. See also... Figure 4 As shown, both the first power supply d 32 and the second power supply b 36 are batteries. The communication device includes a fourth RF chip 31, a first power supply d 32, a capacitor c 34, a second power supply b 36, a first inductor b 37, and a second inductor 38. The fourth RF chip 31 and capacitor c 34 are connected in series with the negative terminal of the first power supply d 32. The second power supply b 36 and the first inductor b 37 are connected in series and then in parallel across the two ends of the first power supply d 32. One end of the first inductor b 37 is connected to the negative terminal of the second power supply b 36, and the positive terminal of the second power supply b 36 is connected to the positive terminal of the first power supply d 32. The other end of the first inductor b 37 is connected to the link between capacitor c 34 and the negative terminal of the first power supply d 32. The second inductor 38 is connected to the other end of the first inductor b 37 and the via c 35. Optionally, both the second inductor 38 and the fourth RF chip 31 are grounded through ground terminal d 33.

[0050] Optionally, it also includes a via c 35; capacitor c 34 is connected to the negative terminal of the first power supply d 32 through via c 35, and the other end of the first inductor b 37 is connected to the link between via c 35 and the negative terminal of the first power supply d 32.

[0051] Based on the above embodiments, in a second aspect, embodiments of this application provide a switch, which also includes the communication device. (See attached document) Figure 5-10 As shown, the switch includes a switch button 41, a housing 42, a wall mount 43, and a PCB board 44. The communication device inside the switch is mounted on the PCB board 44.

[0052] Furthermore, the communication device includes at least one battery.

[0053] When the at least one battery is a single battery, the first power source for the communication device is the single battery in the switch. This can be achieved using... Figure 1 Related technical solutions.

[0054] When the at least one battery is a plurality of batteries, the plurality of batteries are connected in parallel; the first power source is any one of the plurality of batteries. Optionally, the plurality of batteries is two, including a first battery a 45 and a second battery a 46. Optionally, it can be adopted... Figure 3 Related technical solutions.

[0055] Specifically, see Figure 6 As shown, the PCB board 44 is provided with a first battery a 45 and a second battery a 46, which are connected in parallel; the positive terminal of the first battery a 45 is connected to the first spring contact 48, and the positive terminal of the second battery a 46 is connected to the second spring contact 47.

[0056] Furthermore, the antenna also includes a via; one end of the via is connected to the link, and the other end of the via is connected to the capacitor; the RF chip is connected in series with the second power supply through the capacitor, the via, and the first inductor in sequence; the RF chip is connected in series with the first power supply through the capacitor and the via in sequence.

[0057] The positive terminal of the first battery a 45 is configured as the receiving and transmitting end of the antenna. The communication device includes a fifth RF chip 51, a capacitor d 52, the first battery a 45, a first inductor c 49, and a second battery a 46.

[0059] Therefore, this embodiment utilizes the battery in the existing switch as an antenna component, saving product design space. By using an existing battery and its metal casing as an antenna component, antenna performance is achieved. This embodiment overcomes the antenna design difficulties caused by the small size of existing battery-powered products, utilizing an existing battery assembly as an antenna component, allowing the battery to both provide power and radiate through the metal casing to achieve antenna functionality.
