Description

Technical Field

[0001] The utility model relates to the technical field of dual - band walkie - talkie antennas, specifically a dual - band walkie - talkie antenna with WIFI function. Background Technique

[0002] A dual - band walkie - talkie antenna is a communication device antenna that can support both VHF and UHF frequency bands simultaneously. The design of this antenna allows it to effectively transmit and receive signals within a relatively wide frequency range, thus meeting the communication requirements of the walkie - talkie at different frequencies. Dual - band walkie - talkie antennas usually have high gain and good directivity to ensure stable and efficient communication services in various communication environments. In addition, dual - band walkie - talkie antennas usually adopt a foldable design, which is convenient for carrying and storage, and also adapts to the usage requirements in different scenarios. Currently, due to size and performance reasons, WIFI frequency bands are generally not directly added to the walkie - talkie antenna. Instead, an external antenna is used for the walkie - talkie frequency band, and WIFI is built - in. This not only realizes the function but also reduces mutual interference. However, because the internal environment of the walkie - talkie is much harsher than that of smart terminals such as mobile phones, the antenna layout and size are very restricted, and the overall cost is relatively high. Moreover, the walkie - talkie antenna needs to be designed separately, which is troublesome and costly. In addition, antenna manufacturers and host manufacturers need to discuss the internal structure design of the walkie - talkie together. The motherboard design is also more complex, requiring the digital ground to be hollowed out and more areas to be reserved for feed points, which affects the miniaturization of the walkie - talkie. Therefore, those skilled in the art have provided a dual - band walkie - talkie antenna with WIFI function to solve the problems raised in the above - mentioned background technique. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dual - band walkie - talkie antenna with WIFI function to solve the problems raised in the above - mentioned background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A dual - band walkie - talkie antenna with WIFI function includes an injection - molded shell, a walkie - talkie antenna structure, and a protection structure. The walkie - talkie antenna structure is fixedly connected inside the injection - molded shell, and the protection structure is fixedly sleeved outside the injection - molded shell. The walkie - talkie antenna structure includes: internal mold forming, walkie - talkie radiator, WIFI radiator, plastic support rod, center pin, connector housing, insulator, and identification color ring. An internal mold forming is opened inside the injection - molded shell, a walkie - talkie radiator is fixedly connected inside the internal mold forming, and plastic support rods are fixedly connected between the walkie - talkie radiators and inside the internal mold forming.

[0006] As a further solution of the utility model: A WIFI radiator is fixedly connected between the plastic support rods and inside the inner mold forming, and a center pin is fixedly connected at the front end of the WIFI radiator and inside the inner mold forming.

[0007] As a further solution of the utility model: A connector housing is fixedly connected at the front end of the center pin and inside the inner mold forming, and an insulator is fixedly connected between the connector housing and the center pin.

[0008] As a further solution of the utility model: An identification color ring is fixedly connected to one end of the injection molding shell.

[0009] As a further solution of the utility model: The identification color ring is a design used to help users quickly identify and distinguish different antennas. These identification color rings are usually located at the root of the antenna and adopt different colors and arrangements so that users can judge the performance and applicable scenarios of the antenna according to the color and position of the identification color ring. The connector housing, insulator, and center pin form a standard 50-ohm SMA connector, and both the intercom radiator and the WIFI radiator are welded to the center pin.

[0010] As a further solution of the utility model: The inner mold forming fixes the intercom radiator. Due to the relatively thin wall thickness, it is easy to deform during the formation of the outer mold. Therefore, plastic support rods are inserted in the middle as support. The identification color ring is pasted on the connector housing. The intercom radiator and the WIFI radiator are in parallel connection. Since the frequency of the WIFI radiator is relatively high, the design length of the common router dipole scheme is too long, and only the monopole scheme can be adopted. However, this scheme is sensitive to length, and the length of the connector housing will seriously affect the performance, while shortening the connector housing can effectively improve the performance.

[0011] As a further solution of the utility model: The protection structure includes: an outer shell protective sleeve, which is fixedly sleeved on the surface of the injection molding shell, and the outer shell protective sleeve is used to protect the injection molding shell and improve the service life of the injection molding shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The identification color ring is a design used to help users quickly identify and distinguish different antennas. These identification color rings are usually located at the root of the antenna and adopt different colors and arrangements so that users can judge the performance and applicable scenarios of the antenna according to the color and position of the identification color ring. The connector housing, insulator, and center pin form a standard 50-ohm SMA connector, and both the intercom radiator and the WIFI radiator are welded to the center pin. The inner mold forming fixes the intercom radiator. Due to the relatively thin wall thickness, it is easy to deform during the formation of the outer mold. Therefore, plastic support rods are inserted in the middle as support;

[0014] 2. The injection-molded housing encloses all components. The identification color ring is pasted on the connector housing. The intercom radiator and the WIFI radiator are connected in parallel. Since the frequency of the WIFI radiator is relatively high, the design length of the common router dipole scheme is too long, so only the monopole scheme can be adopted. However, this scheme is sensitive to length, and the length of the connector housing will seriously affect the performance. Shortening the connector housing can effectively improve the performance.

[0015] 3. Use the housing protective sleeve to protect the injection-molded housing and improve the service life of the injection-molded housing. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0021] Refer to Figures 1-3, this embodiment provides a dual - band walkie - talkie antenna with WIFI function, including an injection - molded housing 1, a walkie - talkie antenna structure, and a protection structure. The walkie - talkie antenna structure is fixedly connected inside the injection - molded housing 1, and the protection structure is fixedly sleeved outside the injection - molded housing 1. The walkie - talkie antenna structure includes: an inner - mold forming 2, a walkie - talkie radiator 3, a WIFI radiator 4, a plastic support rod 5, a center pin 6, a connector housing 7, an insulator 8, and an identification color ring 9. An inner - mold forming 2 is provided inside the injection - molded housing 1. A walkie - talkie radiator 3 is fixedly connected inside the inner - mold forming 2. A plastic support rod 5 is fixedly connected between the walkie - talkie radiators 3 and inside the inner - mold forming 2. A WIFI radiator 4 is fixedly connected between the plastic support rods 5 and inside the inner - mold forming 2. A center pin 6 is fixedly connected at the front end of the WIFI radiator 4 and inside the inner - mold forming 2. A connector housing 7 is fixedly connected at the front end of the center pin 6 and inside the inner - mold forming 2. An insulator 8 is fixedly connected between the connector housing 7 and the center pin 6. An identification color ring 9 is fixedly connected at one end of the injection - molded housing 1. The identification color ring 9 is a design used to help users quickly identify and distinguish different antennas. These identification color rings 9 are usually located at the root of the antenna and use different colors and arrangements so that users can judge the performance and applicable scenarios of the antenna according to the color and position of the identification color ring 9. The connector housing 7, the insulator 8, and the center pin 6 form a standard 50 - ohm SMA connector. The walkie - talkie radiator 3 and the WIFI radiator 4 are both welded to the center pin 6. The inner - mold forming 2 fixes the walkie - talkie radiator 3. Since the wall thickness is relatively thin, it is easy to deform when forming the outer mold. Therefore, a plastic support rod 5 is inserted in the middle as a support. The injection - molded housing 1 wraps all the components. The identification color ring 9 is pasted on the connector housing 7. The walkie - talkie radiator 3 and the WIFI radiator 4 are in parallel. Since the frequency of the WIFI radiator 4 is relatively high, the commonly used router - type dipole scheme design has too long a length, so only a monopole scheme can be used. However, this scheme is sensitive to length, and the length of the connector housing 7 will seriously affect the performance, while shortening the connector housing 7 can effectively improve the performance. Embodiment 2

[0022] Refer to Figures 1-3 , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that the protection structure includes: an outer - shell protective sleeve 10. The outer - shell protective sleeve 10 is fixedly sleeved on the surface of the injection - molded housing 1 to protect the injection - molded housing 1 and improve the service life of the injection - molded housing 1.
