[0016] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0017] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, such as welding, riveting, bonding, etc., or a detachable connection, such as threaded connection, key connection, pin connection, etc., or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] As Figure 1-2 shown, a Bluetooth antenna proposed by the present utility model includes a connector base 1, a housing 2, and an antenna assembly. The antenna assembly is disposed inside the housing 2 and connected to its inner wall. The connector base 1 is located inside the housing 2, one end thereof extends out of the housing 2, and the other end thereof is integrally designed with the antenna assembly.

[0020] In the present utility model, during the installation of the device, due to the integral design of the antenna assembly and the connector base 1, when assembling the device, it is only necessary to connect the antenna assembly to the inner wall of the housing 2 to complete the installation of the device (when installing the antenna assembly, 3M glue can be applied to the antenna assembly to adhere it to the inner wall of the housing 2 through 3M glue, thereby completing the installation of the antenna assembly). There is no need for the staff to manually rotate the connector base 1 to complete the connection between the connector base 1 and the antenna assembly, thus effectively improving the work efficiency of the staff when installing the device.

[0021] In an alternative embodiment, the antenna assembly includes a PCB antenna board 3. The PCB antenna board 3 is spirally arranged. One end of the PCB antenna board 3 is connected to the inner wall of the housing 2, and the other end of the PCB antenna board 3 is integrally connected to the connector base 1. The spiral arrangement of the PCB antenna board can reduce the length of the PCB antenna board 3 while ensuring a certain perimeter, thereby effectively reducing the length of the housing 2 that houses the PCB antenna board 3, so that the device is overall reduced in size while ensuring its performance, making it more convenient to carry and use.

[0022] In an alternative embodiment, the perimeter of the PCB antenna board 3 is one-quarter wavelength of 2400 - 2500 MHz, and the length is 24 - 30 mm. The perimeter of the PCB antenna board 3 being one-quarter wavelength of 2400 - 2500 MHz and the length being 24 - 30 mm enables the Bluetooth antenna to have a good voltage standing wave ratio (VSWR) within the frequency range and a relatively high gain, fully meeting the requirements of Bluetooth wireless communication.

[0023] In an alternative embodiment, the connector base 1 and the PCB antenna board 3 are integrally connected by welding. Welding can connect the connector base 1 and the PCB antenna board 3, enabling integral installation during installation, thereby reducing the installation difficulty of the device.

[0024] In an alternative embodiment, a plurality of positioning posts 4 are provided on the outer shell 2, and positioning holes equal in number to and corresponding one by one to the plurality of positioning posts 4 are provided on the joint seat 1. The positioning posts 4 pass through the positioning holes and are connected to the joint seat 1 by hot melting. When installing the joint seat 1, the PCB antenna board 3 is placed inside the outer shell 2, and a plurality of positioning posts 4 pass through the corresponding positioning holes, and the positioning posts 4 are subjected to hot melting and extrusion treatment, so that the hot-melted positioning posts 4 fit with the joint seat 1 after being extruded, thereby further fixing the joint seat 1, and effectively improving the overall firmness of the device.

[0025] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
