[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] There is a 450MHz walkie-talkie antenna that provides one-to-one and one-to-many communication modes. It is not limited by the network coverage of operators and is suitable for use in extreme environments such as wilderness, snowfields, and woodlands.

[0004] However, in the aforementioned special environmental conditions, the robustness, sealing, and waterproofing performance of the product face certain challenges. This is especially true for the antenna assembly of walkie-talkies, which is typically a raised rod with a fragile structure, making it more susceptible to external contamination under special circumstances, leading to water seepage or structural damage. Current antenna assembly structures generally address these issues by strengthening the materials, but this is costly.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a walkie-talkie antenna device that enhances the stability of the antenna radome by engaging with the ribs of the antenna radome through a slot on the connector, and further enhances the waterproof performance through the abutment part of the connector.

[0007] To achieve the above objectives, this utility model discloses a walkie-talkie antenna device for connecting to a walkie-talkie body, the walkie-talkie antenna device comprising:

[0008] A connector having a first end and a second end disposed opposite to each other, the first end of the connector being used to connect to the walkie-talkie body, the first end of the connector including a recessed groove between the second end of the connector, and the first end of the connector including a mounting portion with a reduced diameter;

[0009] The radome has a cavity extending from a second end to a first end. The second end of the radome includes a rib whose size matches the size of the slot. The rib is used to insert into the slot of the connector to limit the axial displacement and circumferential rotation of the radome and the connector.

[0010] A coil is disposed within the cavity of the radome, and the second end of the coil is sleeved on the mounting portion of the connector;

[0011] The connector has an abutment portion on the side of the slot facing the second end of the connector, the abutment portion being used to abut against the end face of the second end of the antenna cover.

[0012] As a further description of the above technical solution, the connector includes convex teeth between the first end and the second end, and the antenna cover includes concave teeth at the second end. The positions and dimensions of the convex teeth and the concave teeth are matched so that the connector and the antenna cover are locked together.

[0013] As a further description of the above technical solution, the coil and the inner wall of the cavity of the antenna cover are bonded together with adhesive.

[0014] As a further description of the above technical solution, the mounting part of the connector has external threads so that the second end of the coil can be rotated and locked onto the mounting part of the connector, and the connection is strengthened by adhesive bonding.

[0015] As a further description of the above technical solution, the second end of the coil is soldered to the mounting portion of the connector.

[0016] As a further description of the above technical solution, an O-ring is provided at the second end of the connector where it is connected to the walkie-talkie body.

[0017] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0018] This utility model discloses a walkie-talkie antenna device. The antenna radome's ribs engage with a slot on the connector. During radome installation, the ribs are secured in the connector's slot, and the connection is reinforced with adhesive. This prevents excessive movement of the radome relative to the connector after installation, resulting in greater stability and improved sealing. Furthermore, the abutment portion at the second end of the connector tightly abuts against the second end face of the radome, further enhancing the product's waterproofness.

Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustration only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0030] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0031] Please see Figure 1-2 This embodiment provides a walkie-talkie antenna device, which includes:

[0032] Connector 1 has a first end and a second end that are disposed opposite to each other. The first end of connector 1 is used to connect to the walkie-talkie body. A recessed groove 11 is included between the first end and the second end of connector 1. The first end of connector 1 includes a mounting portion 12 with a reduced diameter.

[0033] The radome 2 has a cavity extending from the second end to the first end. The second end of the radome 2 includes a rib 21. The size of the rib 21 matches the size of the slot 11. The rib 21 is used to insert into the slot 11 of the connector 1 to limit the axial displacement and circumferential rotation of the radome 2 and the connector 1.

[0034] Coil 3 is disposed inside the cavity of antenna cover 2, and the second end of coil 3 is sleeved on the mounting part 12 of connector 1;

[0035] The connector 1 has an abutment portion 13 on the side of the slot 11 facing the second end of the connector 1, and the abutment portion 13 is used to abut against the end face of the second end of the antenna cover 2.

[0036] For the above structure, during installation, simply put the coil 3 on the mounting part 12 of the connector 1 and insert them into the antenna cover 2. During this process, the protruding rib 21 at the second end of the antenna cover 2 is locked into the slot 11 of the connector 1 for fixation, and the abutting part 13 is pressed against the end face of the second end of the antenna cover 2. Then, the connector 1 with the coil 3 and the antenna cover 2 is connected to the external walkie-talkie body.

[0037] With the above structure, during use, in extreme environments where external liquids may penetrate, the outward protrusion of the contact part 13 forms a first protective layer with the end face of the second end of the antenna radome 2, significantly improving its waterproof performance compared to a device without the contact part 13. Furthermore, the cooperation of the slot 11 and the rib 21, along with the adhesive, forms a second protective layer inside the antenna radome 2, further enhancing its waterproof performance compared to a device without the slot 11. Simultaneously, the cooperation of the slot 11 and the rib 21 limits the movement or rotation between the connector 1 and the antenna radome 2, thus making the antenna radome 2 more stably fixed relative to the walkie-talkie body, enhancing its structural strength.

[0038] Furthermore, the connector 1 includes a raised tooth 14 between its first and second ends, and the radome 2 includes a recessed tooth 22 at its second end. The positions and dimensions of the raised tooth 14 and the recessed tooth 22 are matched to lock the connector 1 and the radome 2 together. Specifically, during the installation process described above, before the rib 21 is inserted into the slot 11, the radome 2 can be screwed onto the connector 1 by rotation thanks to the cooperation of the raised tooth 14 and the recessed tooth 22. After being fully fixed, the friction between the raised tooth 14 and the recessed tooth 22 enhances the stability of the connection between the connector 1 and the radome 2.

[0039] Furthermore, the coil 3 and the inner wall of the radiator 2 cavity are bonded together with glue. The glue connection in this embodiment can effectively improve the stability of the coil 3, avoid shaking and misalignment, and the coil 3 itself is lightweight, so the glue fixation effect is good and the cost is low.

[0040] Furthermore, the mounting portion of connector 1 has external threads, allowing the second end of coil 3 to be rotated and secured onto the mounting portion 12 of connector 1. This threaded installation method is easier and provides strong axial restraint, preventing detachment. Specifically, the second end of coil 3 is further soldered to the mounting portion 12 of connector 1, making its fixation to connector 1 more stable.

[0041] Furthermore, an O-ring 4 is provided at the second end of the connector 1 where it connects to the walkie-talkie body. The waterproof effect of this embodiment can be further improved by the barrier provided by the O-ring 4.

[0042] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.
