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.

[0036] It should be noted that in the present embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "rear" and the like are based on the directions or positional relationships shown in the drawings, and are merely for the convenience of describing the present application and simplifying the description, and thus cannot be understood as limiting the present application in indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus cannot be understood as limiting the present application. In addition, "first", "second", "third", "fourth" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0037] In order for 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 drawings and specific embodiments.

[0038] Please refer to Figures 1 to 6 In the present embodiment, an antenna positioning structure is provided, which comprises a positioning portion 2 and a supporting portion 3. The positioning portion 2 comprises an upper positioning portion 24 and a lower positioning portion 21. The first circuit board 6 and the second circuit board 1 are respectively clamped on the upper positioning portion 24 and the lower positioning portion 21. The upper positioning portion 24 is fixedly connected with the lower positioning portion 21, thereby ensuring the overall structural stability of the positioning portion 2.

[0039] An arc-shaped protrusion 23 is arranged on the side of the lower positioning portion 21 facing the upper positioning portion 24. The supporting portion 3 comprises a supporting ring abutting against the lower positioning portion 21 at one end, i.e. the supporting ring is sleeved from the side of the upper positioning portion 24, and the end of the supporting ring gradually approaches the lower positioning portion 21 until the end of the supporting ring abuts against the lower positioning portion 21. When the supporting ring abuts against the lower positioning portion 21, the inner circle of the supporting ring is also sleeved on the outer periphery of the arc-shaped protrusion 23, i.e. the arc-shaped protrusion 23 and the upper surface of the lower positioning portion 21 form a shoulder structure, which can be an annular shoulder. On the basis of the shoulder structure, the arc-shaped protrusion 23 can abut against the inner circle of the supporting ring, thereby positioning the supporting ring on the lower positioning portion 21 and ensuring the stable arrangement of the supporting ring.

[0040] The other end of the supporting ring extends towards the upper positioning portion 24, thereby forming a supporting ring having a certain length in the axial direction. The antenna 5 can be sleeved on the outer periphery of the supporting ring for limiting the antenna 5. In one embodiment, the inner circle of the antenna 5 abuts against the outer wall of the supporting ring. On the basis of the stable arrangement of the supporting ring, the antenna 5 can also be stably arranged in the form of annular abutment, thereby avoiding the inclination, shaking or deformation of the antenna 5. Of course, in another embodiment, the inner circle of the antenna 5 can also abut against part of the outer wall of the supporting ring, or even without abutment, the limiting connection between the two can be achieved by some other auxiliary components, which all fall within the protection scope of the present application.

[0041] In combination with the above embodiments, the antenna 5 has a stable support structure through the cooperation of the positioning portion 2 and the support portion 3. Specifically, the positioning portion 2 includes an upper positioning portion 24 and a lower positioning portion 21, which are fixedly connected to ensure the stability of the positioning portion 2. The support portion 3 includes a support ring abutting against the lower positioning portion 21 at one end, and the inner circle of the support ring can abut against the outer periphery of the arc-shaped protrusion 23 on the lower positioning portion 21, thereby providing a stable support structure for the support ring. The antenna 5 is sleeved on the outer periphery of the support ring. On the basis of the stable support structure of the support ring, the inner circle of the antenna 5 abuts against the outer wall of the support ring, thereby making the antenna 5 have a stable structure and avoiding the antenna 5 from tilting, shaking or deforming, and improving the stability of the signal of the antenna 5 and the stability of signal transmission.

[0042] In addition, the antenna positioning structure of the present application also includes a lamp panel cover 4, which functions to fix the lamp panel. The LEDs and lenses on the lamp panel pass through the lamp panel cover 4. For details, please refer to the prior art, which will not be described here. Please refer to Figure 5 and Figure 6 The lamp panel cover 4 is arranged at the extended end of the support ring and includes a cover body 41 abutting against the end of the support ring and an annular wall 42 arranged at the outer edge of the cover body 41. The annular wall 42 is sleeved on the outer periphery of the extended end of the support ring, and the inner wall of the annular wall 42 abuts against the outer wall of the support ring. The cover body 41 can axially limit the support ring to prevent the support ring from moving or shaking axially. The annular wall 42 can limit the outer wall of the support ring to improve the stability of the support ring in cooperation with the arc-shaped protrusion 23.

[0043] In some embodiments, the support ring is a C-shaped support ring with an opening at one side. Please refer to Figure 1 and Figure 2 The antenna 5 usually has only one pin 51 fixedly connected to the circuit board and electrically connected to the circuit board. Therefore, in order to enable the pin 51 to pass through the support ring and be connected to the circuit board, an opening can be arranged on the support ring. The pin 51 of the antenna 5 passes through the opening into the inner circle of the support ring and is welded to the second circuit board 1.

[0044] On the basis of the stable arrangement of the circuit board, the positioning structure of the present application can keep the antenna 5 stably arranged relative to the circuit board.

[0045] In some embodiments, the second circuit board 1 is provided with a limiting gap 11. Please refer to Figure 3 The lower positioning portion 21 is provided with a limiting protrusion 22 abutting against the limiting gap 11. Please refer to Figure 4 The limiting protrusion 22 can be inserted into the limiting gap 11, thereby achieving the limiting connection between the lower positioning portion 21 and the second circuit board 1 and ensuring the stability of the positioning portion 2. Of course, the arrangement of the limiting gap 11 cannot affect the performance of the second circuit board 1 itself. Multiple limiting gaps 11 can be arranged at different positions according to actual conditions.

[0046] Further, to ensure the stability of the connection between the lower positioning part 21 and the second circuit board 1, the number of limiting notches 11 is at least two, and the corresponding limiting protrusions 22 are consistent with the number of limiting notches 11. At the same time, the limiting notches 11 are respectively located on both sides of the second circuit board 1, so as to ensure that the lower positioning part 21 is at least connected with the second circuit board 1 on both sides through clamping, thereby improving the stability of the positioning part 2.

[0047] In addition, since the antenna 5 is connected with the second circuit board 1 through a pin 51, and the presence of the lower positioning part 21 may affect the welding and fixing position of the pin 51 and the second circuit board 1, therefore, an avoiding notch 26 can be arranged on the lower positioning part 21, so that the pin 51 can pass through the lower positioning part 21 and be connected with the second circuit board 1. For details, please refer to Figure 4 .

[0048] The upper positioning part 24 is provided with a plurality of limiting protrusions 25. Please refer to Figure 4 , the first circuit board 6 is placed on the upper positioning part 24 between the plurality of limiting protrusions 25, so that on the basis of the stable arrangement of the positioning part 2, the first circuit board 6 can also be stably placed.

[0049] The antenna positioning structure of the present application must be made of non-metallic materials, such as polytetrafluoroethylene, ABS plastic and other non-metallic materials with little effect on signal transmission. If metal materials are used, the signal performance of the antenna 5 will be affected. Specifically, the upper positioning part 24 and the lower positioning part 21 are integrally formed of non-metallic materials, and the support part 3 and the lamp panel cover 4 are also made of non-metallic materials. In this way, the overall structural strength and stability of the antenna positioning structure can be ensured while ensuring the signal transmission effect.

[0050] The present application also provides an antenna structure, which comprises a circuit board, an antenna 5 and an antenna positioning structure. The antenna positioning structure is the above-mentioned antenna positioning structure. The circuit board comprises a first circuit board 6 and a second circuit board 1, and the two circuit boards are electrically connected. The main part of the antenna 5 is a circular ring structure, and a pin 51 is welded and electrically connected with the second circuit board 1. Therefore, the antenna structure can also avoid the situation that the antenna 5 is inclined, shaken or deformed, thereby improving the stability of the signal of the antenna 5 and the stability of the signal transmission.

[0051] The present application also provides a double-lens capsule endoscope, which comprises a capsule shell, an image acquisition module and an antenna structure. The antenna structure is the above-mentioned antenna structure. The capsule shell can refer to the capsule shell of the prior art. The number of image acquisition devices is two, which are arranged in the capsule shell and are electrically connected with the first circuit board 6 and the second circuit board 1 respectively. The image acquisition devices can shoot the picture of the capsule endoscope in the human body, and transmit the signal to the receiver outside the human body through the circuit board and the antenna 5, so that the picture shot by the capsule endoscope in the human body can be observed.
