Description

Technical Field

[0001] The present invention relates to the technical field of radios, and in particular, to an antenna device for a radio and a radio. Background Art

[0002] Video conferencing, as an important means of remote collaboration, is an efficient communication method. The radio used in the conference needs to be used in normal scenarios and also needs to meet the requirements for use in charging scenarios. The charging base of the radio is a box-shaped device similar to a mouth shape, and the radio can be inserted into the charging base on either side for charging. In the conventional radio antenna design, such as in the form of an on-board or FPC, due to the limitation of the charging structure (which is made of metal) around the radio, the radiation and signal reception capabilities of the antenna are affected, and good performance cannot be achieved. When randomly inserting one side of the radio into the charging base during the charging process, the antenna design may be placed in the charging base at any position of the radio. Since the charging base is made of metal, if the part placed in the charging base is designed as an antenna, the antenna performance will deteriorate further and the connection cannot be maintained.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0023] See Figure 1, which is a schematic structural diagram of an antenna device of a radio provided by an embodiment of the present invention. The device 1 includes: a first charging structure 11 and an antenna antenna 12; the first charging structure 11 is connected to the ground on the radio circuit board 2. The first charging structure 11 includes a charging device 111 and a grounding antenna 112. The charging device 111 is respectively wrapped around the corners of the circuit board 2; one ends of the antenna antenna 12 and the grounding antenna 112 are both installed on the circuit board 2, and the other ends are both installed on the charging device 111; the antenna antenna 12 is connected to the radio frequency device 21 on the circuit board 2.

[0024] On the basis of the above embodiment, in a preferred embodiment, the antenna antenna 12 and the grounding antenna 112 are installed on adjacent sides of the charging device 111.

[0025] It should be noted that, please refer to Figure 1 , the radio is commonly square and flat. The charging device 111 in the first charging structure 11 is wrapped around the corners of the radio circuit board 2, in a right angle shape, or can also be in a rounded corner shape. The shape of the charging structure is not limited here. The two vertical sides (side A and side B) of the first charging structure 11, that is, the charging device 111, need to be designed according to the wavelength corresponding to the frequency of the wireless signal for actual use, that is, λ = c / f, where λ is the wavelength, c is the speed of light, and f is the frequency. In addition, the positions of the antenna antenna 12 and the grounding antenna 112 on the charging structure need to be designed according to the actual situation, related to the signal wavelength, related to the appearance structure, and the design of the relative positions of the two antennas is related to the performance of the antenna device 1. Among them, the change in the relative positions of the antenna antenna 12 and the grounding antenna 112 is specifically the horizontal movement of the grounding antenna on side A and the vertical movement of the antenna antenna on side B. Specifically, one signal wavelength corresponds to one antenna length, and the antenna length ≈ λ / 4. Different widths will have a slight impact on the required antenna length, and different materials will also cause slight changes in the antenna length. At the same time, the relative change in the positions of the antenna antenna 12 and the grounding antenna 112 will also affect the antenna length.

[0026] On the basis of the above embodiment, in another preferred embodiment, the antenna antenna 12 and the grounding antenna 112 are installed on the same side of the charging device 111. Among them, the change in the relative positions of the antenna antenna 12 and the grounding antenna 112 is specifically the horizontal movement of the antenna antenna 12 and the grounding antenna 112 on side A or the vertical movement on side B.

[0027] Specifically, the radio frequency device 21 is preferably a radio frequency chip. By providing the antenna antenna 12, the signal transmitted by the radio frequency device 21 is transmitted to the antenna antenna 12 to be emitted to an external device, and the signal from the external device is transmitted to the radio frequency device 21 through the antenna antenna 12, so as to realize data interaction between the radio receiver and the external device.

[0028] In some embodiments, the antenna antenna 12 and the first charging structure 11 are an integrated structure. In the present invention, the antenna antenna 12 and the first charging structure 11 are designed as an integrated structure. Specifically, the antenna antenna 12 and the charging device 111 are an integrated structure, where the positions on the radio receiver circuit board 2 that are in contact with the antenna antenna 12 and the charging device 111 are copper-exposed. After the antenna antenna 12 and the charging device 111 are assembled, welding is performed, which facilitates installation and reduces the installation cost.

[0029] An antenna device of a radio receiver provided by an embodiment of the present invention, the device includes a first charging structure and an antenna antenna. The first charging structure is connected to the ground on the radio receiver circuit board. The first charging structure includes a charging device and a grounding antenna. The charging device is respectively wrapped around the corners of the circuit board. One end of the antenna antenna and the grounding antenna are both installed on the circuit board, and the other end is both installed on the charging device. The antenna antenna is connected to the radio frequency device on the circuit board. Through the above structure, the first charging structure combined with the antenna antenna is used as the antenna device. The antenna device is arranged on the outermost side of the radio receiver, and there are no restrictions and interferences from any metals or the like around it, which greatly improves the radiation and signal reception capabilities of the antenna, and can effectively improve the performance of the antenna during the non-charging use process of the radio receiver. At the same time, compared with the structure of the antenna arranged on the circuit board in the prior art, the antenna structure in this embodiment is not restricted, and there is no need to reserve space for the antenna on the circuit board, which simplifies the antenna structure, reduces the complexity of the antenna structure, and thus reduces the cost.

[0030] See Figure 2 , which is a schematic structural diagram of a radio receiver provided by an embodiment of the present invention. The radio receiver includes: a circuit board 2, a second charging structure 3, and the antenna device 1 of the above-mentioned radio receiver; the second charging structure 3 is connected to the positive power supply on the circuit board 2. The antenna device 1 and the second charging structure 3 are respectively connected to the circuit board 2, and the antenna device 1 and the second charging structure 3 are arranged on adjacent corners of the circuit board 2.

The charging device 111 is respectively wrapped around the corners of the circuit board 2; one end of the positive antenna 31 is installed on the circuit board 2, and the other end is installed on the charging device 111.

[0032] It should be noted that the charging device 111 in the second charging structure 3 is wrapped around the corners of the circuit board 2 of the radio, forming a right angle or a rounded corner. The shape of the charging structure is not limited here. Please refer to Figure 2 , the charging devices at the four corners of each circuit board 2 are disconnected from each other and not connected. The internal structures of adjacent charging structures on the radio are different from each other, so that any side can be inserted into the charging base for charging during charging. In addition, the shapes of adjacent charging structures on the radio can be the same or different, which is not limited here.

[0033] A radio provided by an embodiment of the present invention, the radio includes: a circuit board, a second charging structure, and an antenna device of the radio. The second charging structure is connected to the positive power supply on the circuit board. The antenna device and the second charging structure are respectively connected to the circuit board. The antenna device and the second charging structure are arranged on adjacent corners of the circuit board. Through the above structure, the antenna performance of the radio during charging and non-charging processes can be effectively improved, and at the same time, the complexity of the radio structure is reduced, the structure of the radio is simplified, and the cost is thus reduced.

[0034] In some embodiments, please refer to Figure 2 , the circuit board 2 is provided with an inductor 22, and the inductor 22 is connected in series between the second charging structure 3 and the positive power supply on the circuit board 2.

[0035] In this embodiment, the inductor 22 can be selected as 22 nh, but this is not limited here. By connecting the inductor 22 in series between the second charging structure 3 and the positive power supply on the circuit board 2, the radio frequency signal interference to the power supply can be effectively prevented.

[0036] In some embodiments, please refer to Figure 2 , the antenna device 1 is connected to both of a pair of opposite corners of the circuit board 2.

[0037] In this embodiment, by arranging the antenna device 1 on a pair of opposite corners of the circuit board 2, it is ensured that no matter which side of the radio is inserted into the charging base, there is an antenna device 1 outside the charging base, ensuring the good performance of the antenna during the charging process of the radio, and improving the real-time performance and accuracy of signal data transmission of the radio. At the same time, the second charging structure 3 is arranged on the other pair of opposite corners of the circuit board 2, so that the antenna device 1 (the first charging device after combining the antenna antenna) and the second charging structure 3 are adjacent to each other at the four corners of the radio, and the good performance of the antenna device can be ensured while charging, which is convenient for use and operation.

[0039] In this embodiment, on the circuit board 2, the antenna antenna 12 is connected to the radio frequency device 21 through the radio frequency microstrip line 23, so as to transmit the signal sent by the radio frequency device 21 to the antenna antenna 12 for transmitting to an external device, and to transmit the signal from the external device to the radio frequency device 21 through the antenna antenna 12, which can effectively improve the reliability of signal transmission and reduce the cost.

[0040] In some embodiments, please refer to Figure 2 , the circuit board 2 is further provided with a capacitor 24, and the capacitor 24 is connected in series between the antenna antenna 12 and the radio frequency microstrip line 23.

[0041] In this embodiment, the capacitor 24 can be selected as 100 pf to achieve the function of passing through AC signals and blocking DC signals. Therefore, by connecting the capacitor 24 in series between the antenna antenna 12 and the radio frequency microstrip line 23, the charging current during charging is prevented from flowing into the radio frequency device 21 and causing damage to the radio frequency device 21.

[0042] It should be noted that the antenna antenna 12, the ground antenna 112, and the positive antenna 31 in the present invention can be installed on the first charging structure 11, the charging device 111, and the circuit board 2 in any of the following ways: First, the antenna and the charging device 111 are an integrated structure, where the copper is exposed at the positions on the radio receiver circuit board that are in contact with the antenna and the charging device 111, and welding is performed after the antenna and the charging device 111 are assembled.
