[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does 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, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please refer to Figures 1 to 3 This embodiment provides an antenna positioning structure, which includes a positioning part and a support part 3. The positioning part includes an upper positioning part 5 and a lower positioning part 2. The lower positioning part 2 is fixedly mounted on the second circuit board 1 of the antenna structure. The support part 3 is fixedly connected to the lower positioning part 2 and the upper positioning part 5, thereby forming a stable support structure. The support part 3 includes at least three support columns 31 located between the upper positioning part 5 and the lower positioning part 2. The antenna 4 is sleeved on the outer periphery of the support columns 31, and any one of the support columns 31 can abut against the inner ring of the antenna 4. Thus, the stable support structure formed by the at least three support columns 31 supports the inner ring of the antenna 4, preventing the antenna 4 from tilting, shaking, or deforming.

[0034] In some embodiments, the antenna 4 typically has only one pin 41 fixed and electrically connected to the second circuit board 1. Based on the stable setting of the second circuit board 1, the positioning structure of this application can keep the antenna 4 stably positioned relative to the second circuit board 1.

[0035] In summary, this application ensures the stability of the positioning structure through the positioning part. The antenna 4 can be sleeved on the outer periphery of the support part 3. Specifically, the support part 3 includes at least three support columns 31 connected to the positioning part. The antenna 4 is sleeved on the outer periphery of the support columns 31. At least three support columns 31 can determine a stable support structure. Thus, through the contact between the support columns 31 and the inner ring of the antenna 4, the antenna 4 is prevented from tilting, shaking or deforming, thereby improving the stability of the antenna 4 signal and the stability of signal transmission.

[0036] In some embodiments, the second circuit board 1 is provided with a limiting notch 11, please refer to Figure 2 The lower positioning part 2 is provided with a limiting protrusion 21 that engages with the limiting notch 11. Please refer to [reference needed]. Figure 3 The limiting protrusion 21 can be inserted into the limiting notch 11, thereby achieving a limiting connection between the lower positioning part 2 and the second circuit board 1, ensuring the overall stability of the positioning part. Of course, the setting of the limiting notch 11 should not affect the performance of the second circuit board 1 itself, and multiple limiting notches 11 can be set in different positions according to the actual situation.

[0037] Furthermore, to ensure the connection stability between the lower positioning part 2 and the second circuit board 1, the number of limiting notches 11 is at least two, and the number of corresponding limiting protrusions 21 is the same as the number of limiting notches 11. At the same time, the limiting notches 11 are located on both sides of the second circuit board 1, ensuring that the lower positioning part 2 is engaged with the second circuit board 1 at least on both sides, thereby improving the stability of the positioning part.

[0038] Furthermore, since the antenna 4 is connected to the second circuit board 1 via a pin 41, and the presence of the lower positioning part 2 may affect the soldering and fixing position of the pin 41 and the second circuit board 1, an avoidance notch 22 can be provided on the lower positioning part 2 to allow the pin 41 to pass over the lower positioning part 2 and connect to the second circuit board 1. For details, please refer to... Figure 3 .

[0039] As for the arrangement of the support column 31, it can be a plate-like structure or a column-like structure, etc. Alternatively, a groove matching the inner ring of the antenna 4 can be opened on the outer wall of the support column 31, so that the antenna 4 can be embedded in the groove structure, thereby improving the compatibility between the antenna 4 and the support column 31 and further improving the stability of the antenna 4.

[0040] The upper positioning part 5 is provided with multiple limiting protrusions 51, please refer to Figure 1The first circuit board is placed on the upper positioning part 5 between multiple limiting protrusions 51, so that the first circuit board can also be placed stably based on the stable setting of the positioning part.

[0041] Furthermore, the antenna positioning structure of this application must be made of non-metallic materials, such as polytetrafluoroethylene, ABS plastic, and other non-metallic materials that have little impact on signal transmission. If metallic materials are used, the signal performance of antenna 4 will be affected. Specifically, the positioning part and the support part 3 are integrally molded structures made of non-metallic materials. While ensuring the use of non-metallic materials, the overall structural strength and stability of the antenna positioning structure can also be guaranteed.

[0042] This application also provides an antenna structure, please refer to... Figure 1 The antenna structure includes a circuit board, antenna 4, and an antenna positioning structure. The antenna positioning structure is the one described above. The circuit board includes a first circuit board and a second circuit board 1. The main body of antenna 4 is a ring-shaped structure, and a pin 41 is soldered to and electrically connected to the second circuit board 1. Therefore, this antenna structure can also avoid situations such as antenna 4 tilting, shaking, or deformation, thus improving the stability of the antenna 4 signal and the stability of signal transmission.

[0043] This application also provides a capsule endoscope, including a capsule shell, an image acquisition module, and an antenna structure, wherein the antenna structure is the antenna structure described above; the capsule shell can refer to the capsule shell of the prior art; the image acquisition device is disposed inside the capsule shell and electrically connected to the second circuit board 1, which can capture images of the capsule endoscope inside the human body, and transmit the signals to a receiver outside the human body through the second circuit board 1 and the antenna 4, thereby allowing observation of the images captured by the capsule endoscope inside the human body.

[0044] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0045] This document uses specific examples to illustrate the principles and implementation methods of this application.
