[0034] Please refer to Figures 1 to 7 This invention discloses an electronic device comprising a tuning structure 100 and a tuning rod 200, the tuning rod 200 engaging and passing through the tuning structure 100. The tuning structure 100 can lock or release the tuning rod 200. In embodiments of this application, the electronic device is used in radio frequency products, including but not limited to filters, duplexers, combiners, tower amplifiers, etc., which are not limited here. In embodiments of this application, the tuning rod 200 is cylindrical. Compared to a conventional screw, the cylindrical wall of the tuning rod 200 does not have a threaded structure. Therefore, during the engagement of the tuning rod 200 with the tuning structure 100, no metal debris is generated, improving the intermodulation and insertion loss of the electronic device.

[0035] Please refer to Figures 1 to 7This application discloses a tuning structure 100 for locking or releasing the tuning rod 200. Specifically, the tuning structure 100 includes a cover plate 1, an adjusting member 2, and an elastic element 3. Specifically, the electronic device has a cavity, the top of which is covered by the cover plate 1. The cover plate 1 has a mounting hole 101 communicating with the cavity. The adjusting member 2 rotatably engages with the wall 11 of the mounting hole 101. The adjusting member 2 has a first through hole 201 at its center, through which the tuning rod 200 can pass. The elastic element 3 is disposed within the mounting hole 101, through which the tuning rod 200 passes. One end of the elastic element 3 abuts against the adjusting member 2, and the other end abuts against the wall 11 of the mounting hole 101. By rotating the adjusting member 2, the elastic element 3 can lock or release the tuning rod 200. When the adjusting member 2 is rotated counterclockwise, the elastic element 3 locks the tuning rod 200, and the tuning rod 200 is fixed in the cavity. When the electronic device needs to be debugged, the adjusting member 2 is rotated, causing the elastic element 3 to release the tuning rod 200. By quickly adjusting the length of the tuning rod 200 entering the cavity, the electronic device can be quickly debugged. Then, the adjusting member 2 is rotated clockwise to position the tuning rod 200 in the cavity.

[0036] Please refer to Figures 2 to 5 The adjusting member 2 has a first fixing part 21, the hole wall 11 has a second fixing part 111, one end of the elastic element 3 abuts against the first fixing part 21, and the other end of the elastic element 3 abuts against the second fixing part 111. When the adjusting member 2 is rotated, the diameter of the elastic element 3 can be contracted or expanded to lock or release the tuning rod 200.

[0037] Please refer to Figures 4 to 5Specifically, the adjusting member 2 includes an annular portion 22, with the first through hole 201 located at the center of the annular portion 22. The outer wall of the annular portion 22 is threadedly connected to the hole wall 11. The first fixing portion 21 is disposed on the inner wall of the annular portion 22, and at least a portion of the elastic element 3 is located within the annular portion 22 and surrounds the inner wall of the annular portion 22. The first fixing portion 21 is a protruding structure or a groove structure. In the embodiment of this application, the first fixing portion 21 is a protruding structure, protruding towards the center of the annular portion 22, and the free end of the elastic element 3 elastically abuts against the first fixing portion 21. When the adjusting member 2 rotates within the mounting hole 101, the first fixing portion 21 can prevent the elastic element 3 from rotating, while the annular portion 22 of the adjusting member 2 can apply pressure to the free end of the elastic element 3, causing the diameter of the elastic element 3 to expand after being compressed, thereby relaxing the tuning rod 200. In other embodiments, the first fixing part 21 is a groove structure, and the free end of the elastic element 3 is inserted into the groove structure.

[0038] Please refer to Figures 4 to 5 The adjusting member 2 further includes an adjusting portion 23, which is disposed on the side of the annular portion 22 away from the cover plate 1. The first through hole 201 passes through the center of the annular portion 22 and the adjusting portion 23, allowing the tuning rod 200 to pass through both the adjusting portion 23 and the annular portion 22. The first through hole 201 has two segments: a first segment located in the adjusting portion 23 and a second segment located in the annular portion 22. The diameter of the first through hole 201 in the adjusting portion 23 is smaller than that in the annular portion 22, such that at least a portion of the elastic element 3 is received within the annular portion 22 and abuts against the first fixing portion 21. An annular gap exists between the annular portion 22 and the radial direction of the resonant rod 200. At least a portion of the elastic element 3 is disposed within the annular gap, and one end of the resonant rod 200 can pass through the first through hole 201, the elastic element 3, and the mounting hole 101. When the tuning rod 200 passes through the first through hole 201, it also passes through the elastic element 3. Rotating the adjusting member 2 can cause the diameter of the elastic element 3 to contract or expand, thereby locking or releasing the tuning rod 200.

[0039] The outer diameter of the annular portion 22 is smaller than the outer diameter of the adjusting portion 23. When the annular portion 22 is threadedly connected to the mounting hole 101, at least a portion of the adjusting portion 23 can abut against the cover plate 1 to limit the position of the adjusting member 2 screwed into the mounting hole 101. Optionally, the edge contour of the adjusting portion 23 is hexagonal to accommodate conventional tools, making it convenient for debugging personnel to rotate the adjusting portion 23 with tools, thereby facilitating the adjustment of the tuning rod 200.

[0040] In an embodiment of this application, the diameter of the first through hole 201 located in the adjustment portion 23 is adapted to the diameter of the tuning rod 200. The diameter of the first through hole 201 located in the adjustment portion 23 is the diameter of the first segment. When the tuning rod 200 passes through the first segment of the first through hole 201, the peripheral wall of the tuning rod 200 abuts against the first segment, so that the tuning rod 200 will not wobble within the first end, thereby improving the stability of the tuning rod 200.

[0041] Please refer to Figures 3 to 4 , Figures 6 to 7 The mounting hole 101 has a hollow annular portion 112 in its wall 11, and the elastic element 3 is disposed between the annular portion 112 and the annular portion 22. Specifically, the annular portion 112 is disposed at the bottom of the mounting hole 11, and the second fixing portion 111 is disposed between the annular portion 112 and the mounting hole 11. The second fixing portion 111 is a protruding structure or a groove structure. In the embodiment of this application, the second fixing portion 111 is a protruding structure, protruding towards the center of the mounting hole 101, and the other free end of the elastic element 3 elastically abuts against the second fixing portion 111. When the adjusting member 2 is screwed counterclockwise into the mounting hole 101, the second fixing portion 111 can prevent the elastic element 3 from rotating. Furthermore, the annular portion 112 supports the other end of the elastic element 3, causing the diameter of the elastic element 3 to expand after being compressed, thereby releasing the tuning rod 200. In other embodiments, the second fixing part 111 is a groove structure, and the other free end of the elastic element 3 is inserted into the groove structure.

[0042] Please refer to Figure 6The annular portion 112 has a second through hole 102 at its center, which communicates with the mounting hole 101. Thus, the tuning rod 200 can sequentially pass through the first through hole 201, the mounting hole 101, and the second through hole 102 before entering the cavity. The diameter of the second through hole 102 is smaller than the diameter of the mounting hole 101. At least a portion of the elastic element 3 is located within the mounting hole 101, and the other end of the elastic element 3 abuts against the annular portion 112, which provides support for the other end of the elastic element 3. The second through hole 102, the mounting hole 101, and the first through hole 201 are concentrically arranged, and the diameters of the second through hole 102 and the first through hole 201 are the same, allowing the tuning rod 200 to move smoothly among these three locations without wobbling.

[0043] Please refer to Figure 4 In this embodiment, the elastic element 3 is a helical spring, the tuning rod 200 passes through the axis of the helical spring, and the tuning rod 200 and the helical spring are interference-fitted so that the helical spring can lock the tuning rod 200. The cross-section of the elastic element 3 is circular or rectangular to increase the friction between the elastic element 3 and the tuning rod 200, so that the tuning rod 200 can be fixed in the mounting hole 101 through the elastic element 3 and is not prone to vertical movement.

[0044] This application also discloses a tuning method for a tuning structure 100, wherein the tuning structure 100 is the tuning structure described above, and the tuning method includes the following steps:

[0045] When the adjusting member 2 is rotated clockwise, one end of the elastic element 3 abuts against the first fixing part 21, and the other end of the elastic element 3 abuts against the second fixing part 111. When the adjusting member 2 is rotated clockwise, both ends of the elastic element 3 rotate clockwise against their own elasticity, causing the diameter of the elastic element 3 to expand.

[0046] Provide the tuning rod 200, pass the tuning rod 200 through the first through hole 201 of the adjusting member 2, the inner side of the elastic element 3 and the mounting hole 101 of the cover plate 1, and wait until the tuning rod 200 extends into the cavity of the electronic device to the required length;

[0047] Rotate the adjusting member 2 counterclockwise, causing the diameter of the elastic element 3 to contract under its own elasticity until the elastic element 3 locks the tuning rod 200.

[0048] In summary, this application discloses an electronic device and a tuning structure 100 for locking or releasing the tuning rod 200. The tuning structure 100 includes a cover plate 1, an adjusting member 2, and an elastic element 3. The cover plate 1 has a mounting hole 101, the adjusting member 2 is rotatably engaged with the wall 11 of the mounting hole 101, the elastic element 3 is disposed within the mounting hole 101, the tuning rod 200 passes through the elastic element 3, and one end of the elastic element 3 abuts against the adjusting member 2, while the other end abuts against the wall 11 of the mounting hole 101. By rotating the adjusting member 2, the elastic element 3 can lock or release the tuning rod 200, thereby allowing the tuning rod 200 to move directly up and down within the tuning structure 100, saving tuning time and improving tuning efficiency.
