[0033] Referring to Figures 1 to 7 The utility model discloses a kind of radio frequency interface fixed structures, comprising: antenna body 10, rotor piece 20, elastic piece 30, cover plate 40, base 50 and antenna seat 60, the cover plate 40 is connected in the base 50 to form containing cavity, the cover plate 40 is equipped with opening 41, the elastic piece 30 and the rotor piece 20 are set in the containing cavity, and the elastic piece 30 is abutted on the inner wall of the rotor piece 20, to make the rotor piece 20 can be moved up and down along the opening 41, the antenna seat 60 is connected in the base 50, the antenna body 10 passes through the opening 41 and is movably connected in the antenna seat 60, when the rotor piece 20 is in first state, the antenna body 10 is separated from the rotor piece 20, when the rotor piece 20 is in second state, the antenna body 10 is locked with the rotor piece 20.

[0034] Specifically, by designing a kind of fixed structure including antenna body 10, rotor piece 20, elastic piece 30, cover plate 40, base 50 and antenna seat 60, it can ensure that antenna body 10 is locked with rotor piece 20 when needed, so as to avoid the case that antenna body 10 appears loose, improve the reliability of radio frequency interface. In addition, the locking and separation between antenna body 10 and rotor piece 20 are realized by the up and down movement of rotor piece 20, when rotor piece 20 is in first state, antenna body 10 is separated from rotor piece 20, which makes antenna body 10 can be easily disassembled or replaced, simplifies the maintenance process of antenna body 10, improves work efficiency. In addition, by ensuring the stable connection of antenna body 10 and facilitating disassembly, the structure helps to improve the overall performance of radio frequency interface, and stable connection can reduce signal loss and interference, while facilitating disassembly makes the maintenance and replacement of antenna body 10 more easy, thereby prolonging the service life of radio frequency interface.

[0035] Among them, elastic piece 30 is spring, when rotor piece 20 is in first state, spring is in compression state at this time;When rotor piece 20 is in second state, spring is in extension state at this time.

[0036] In an embodiment, the rotor member 20 is provided with a fastening end 21, and the antenna body 10 is movably connected to the antenna seat 60 through the fastening end 21. When the rotor member 20 is in the first state, the antenna body 10 is separated from the fastening end 21. When the rotor member 20 is in the second state, the antenna body 10 is locked with the fastening end 21.

[0037] Specifically, when the rotor member 20 is in the second state, the antenna body 10 is locked with the fastening end 21. This locking mechanism ensures that the antenna body 10 will not loosen or fall off during use due to external forces or vibrations, thereby ensuring stable transmission of radio frequency signals. When the rotor member 20 is in the first state, the antenna body 10 is separated from the fastening end 21. This design allows the antenna body 10 to be easily detached from the antenna seat 60, facilitating maintenance or replacement. In addition, due to the locking mechanism between the antenna body 10 and the fastening end 21, it can be ensured that radio frequency signals will not be lost during transmission due to unstable connection, thereby improving the reliability of the radio frequency interface. The locking mechanism also reduces wear caused by loosening of the antenna body 10, thereby extending the service life of the radio frequency interface. In addition, by adjusting the state of the rotor member 20, the locking and separation between the antenna body 10 and the fastening end 21 can be easily achieved, thereby meeting different use requirements. For example, in scenarios where the antenna body 10 needs to be quickly replaced, the rotor member 20 can be placed in the first state to easily detach the antenna body 10. In addition, since the locking and separation between the antenna body 10 and the fastening end 21 can be achieved by adjusting the state of the rotor member 20, the maintenance and replacement operations of the antenna body 10 are greatly simplified.

[0038] Referring to Figures 1 to 5 In the first embodiment shown, the cover plate 40 is provided with a sliding groove 42, and the rotor member 20 is provided with a rotating column 22 corresponding to the sliding groove 42. When the rotating column 22 is connected to one side of the sliding groove 42, the rotor member 20 is in the first state. When the rotating column 22 is connected to the other side of the sliding groove 42, the rotor member 20 is in the second state.

[0039] Specifically, by designing the sliding groove 42 on the cover plate 40 and the rotating column 22 on the rotor 20, the two can cooperate with each other to realize the stable conversion of the rotor 20 between the two states. The sliding groove 42 provides a clear movement track for the rotating column 22, ensuring the stability and accuracy of the rotor 20 during the conversion process. When the rotating column 22 is connected to one side of the sliding groove 42, the rotor 20 is in the first state; when the rotating column 22 is connected to the other side of the sliding groove 42, the rotor 20 is in the second state. This design makes the state conversion clear and easy to control, and the operator can clearly know the current state of the rotor 20. In addition, through the cooperation of the sliding groove 42 and the rotating column 22, the operator only needs to simply move the rotating column 22 to complete the state conversion of the rotor 20, without the need for complex operation steps or tools, which greatly simplifies the operation process and improves the work efficiency.

[0040] Referring to Figures 1 to 5 In the first embodiment shown, one side of the sliding groove 42 is provided with a hook 43, and the other side is provided with a limiting groove 44.

When the hook 43 is connected to the clamping groove 23, the rotor 20 is in the first state; when the rotating column 22 is connected to the limiting groove 44, the rotor 20 is in the second state.

[0041] Specifically, when the clamping hook 43 is connected to the clamping groove 23, the rotor piece 20 is in the first state (initial state), at this time the spring is in the compressed state, the fastening end 21 is located below the antenna body 10, the antenna body 10 is rotated to be connected with the antenna seat 60, then the rotating column 22 is pressed to separate the clamping hook 43 from the clamping groove 23, the rotor piece 20 moves upward along the opening 41 under the action of the spring, then the rotating column 22 is rotated to the other side of the sliding groove 42 with the antenna body 10 as the axis, and until the rotating column 22 is connected to the limiting groove 44, a clamping fit is formed (under the action of the spring, the rotating column 22 abuts against the limiting groove 44, so that the rotating column 22 cannot be separated from the limiting groove 44), that is, the rotor piece 20 is in the second state (terminal state), during the rotation of the rotating column 22, the fastening end 21 is engaged with the antenna body 10, a locking state is formed. That is, when the clamping hook 43 is connected to the clamping groove 23, the rotor piece 20 is in the initial state, at this time the spring is in the compressed state, energy is stored for the subsequent unlocking action, the fastening end 21 is located below the antenna body 10, and the antenna body 10 is prepared for connection with the antenna seat 60, the antenna body 10 can be rotated by an operator to be correctly aligned with and connected to the antenna seat 60, then the rotating column 22 is pressed to separate the clamping hook 43 from the clamping groove 23; at this time, the rotor piece 20 moves upward along the opening 41 under the action of the spring, and space is provided for subsequent rotation, then the rotating column 22 is rotated to the other side of the sliding groove 42 with the antenna body 10 as the axis; when the rotating column 22 is connected to the limiting groove 44, the rotor piece 20 is in the terminal state, at this time the rotating column 22 forms a clamping fit with the limiting groove 44, and the rotor piece 20 cannot be moved at will, while during the rotation of the rotating column 22, the fastening end 21 is engaged with the antenna body 10, a locking state is formed, and stable connection between the antenna body 10 and the antenna seat 60 is ensured, so that the antenna body 10 cannot be loosened due to vibration.

[0042] Referring to Figure 6 As shown in the second embodiment, the inner side of the fastening end 21 is further provided with a silica gel ring 70 which is large at the top and small at the bottom, when the rotor piece 20 is pressed to be in the first state, and when the rotor piece 20 is released to be in the second state.

[0043] Specifically, when the rotor piece 20 is pressed, at this time the spring is in the compressed state, the rotor piece 20 goes down with the silica gel ring 70, is in the first state, and the fastening end 21 is located below the antenna body 10, the antenna body 10 is rotated to be connected with the antenna seat 60, then the rotor piece 20 is released, the rotor piece 20 moves upward along the opening 41 with the silica gel ring 70 under the action of the spring, so that the silica gel ring 70 is clamped to the antenna body 10, a locking state is formed, at this time the rotor piece 20 is in the second state (terminal state).

[0044] In an embodiment, the lower end of the antenna body 10 is provided with an external hexagonal end 11, and the fastening end 21 is an internal hexagonal end, which is fitted with the external hexagonal end 11 to form a lock.

[0045] Specifically, the external hexagonal end 11 and the internal hexagonal end are both in the shape of a regular hexagon, which has high symmetry and stability, and can ensure accurate alignment and stable locking during connection; when the internal hexagonal end is completely fitted with the external hexagonal end 11, a tight locking effect will be formed between them, thereby effectively preventing the antenna body 10 from loosening or falling off during connection. In addition, the design of the rotation starting to ending angle is greater than 60°, which means that during the rotation process, the external hexagonal end 11 and the internal hexagonal end will have enough time and space to find and reach the best fitting point. Within this rotation angle range, due to the symmetry of the regular hexagon, there must be a fitting point between the external hexagonal end 11 and the internal hexagonal end, and this design ensures the reliability and accuracy of the connection process.

[0046] In an embodiment, the base 50 is provided with a guide column 51, and the lower end of the elastic member 30 is sleeved on the guide column 51.

[0047] Specifically, the design of the guide column 51 enables the lower end of the elastic member 30 to be firmly sleeved on the guide column 51, thereby effectively preventing the elastic member 30 from shifting or deviating from the predetermined position during use. Through the guidance and support of the guide column 51, the elastic member 30 can maintain its original shape and size, thereby ensuring that it can provide stable and uniform elastic force when under stress. In addition, the presence of the guide column 51 provides clear positioning for the installation of the elastic member 30, making the installation process more convenient and efficient. During maintenance, the guide column 51 can serve as a reference point for checking and replacing the elastic member 30, which helps to ensure the accuracy and efficiency of the maintenance work.

[0048] In an embodiment, the base 50 located at the outer periphery of the guide column 51 is also provided with a recess 52, and the elastic member 30 is placed in the recess 52.

[0049] Specifically, the groove 52 provides a clear placement position for the elastic element 30, effectively preventing the elastic element 30 from shifting due to uneven force or external interference during use. This design ensures that the elastic element 30 always remains in the predetermined position, providing stable elastic force. In addition, the groove 52 limits the movement range of the elastic element 30 in the horizontal direction, allowing it to only stretch and contract along the axial direction of the guide column 51 when under stress, avoiding unnecessary lateral movement and further improving stability. Additionally, by designing the groove 52, the elastic element 30 can be effectively placed in a limited space, improving the compactness of the entire structure, which is particularly important for application scenarios that require strict control of volume and weight. Furthermore, the presence of the groove 52 provides clear guidance for the assembly of the elastic element 30, making the assembly process more convenient and efficient, reducing assembly difficulty and cost.

[0050] In an embodiment, the inner wall of the rotor element 20 is provided with a stepped groove, and the elastic element 30 abuts against the stepped groove.

[0051] Specifically, the stepped groove provides a clear positioning point for the elastic element 30, allowing it to stably abut and fix within the stepped groove, thereby preventing the elastic element 30 from shifting or wobbling inside the rotor element 20. In addition, since the elastic element 30 is stably positioned within the stepped groove, it can output elastic force in a more stable manner, which is particularly important for application scenarios that require precise control of elastic force output. Furthermore, the design of the stepped groove can also prevent the elastic element 30 from loosening due to long-term use or vibration, thereby prolonging the service life of the entire structure.

[0052] Referring to Figure 7 In the illustrated third embodiment, the cover plate 40 is provided with a sliding groove 42, and the rotor element 20 is provided with a screw 80 corresponding to the sliding groove 42, the screw 80 passes through the sliding groove 42 and is connected to the rotor element 20; pressing the screw 80 to make the rotor element 20 in the first state, and tightening the screw 80 to make the rotor element 20 in the second state.

[0053] Specifically, the screw 80 passes through the sliding groove 42 and is threadedly connected to the rotor element 20. When the screw 80 is loosened on one side of the sliding groove 42, pressing the screw 80 drives the rotor element 20 to compress the spring, making the rotor element 20 as a whole in the first state, i.e., the rotor element 20 is separated from the antenna body 10, which can realize the disassembly of the antenna body 10; taking the screw 80 as a handle, rotating the rotor element 20 to make the antenna body 10 form a fitting state with the fastening end 21, realizing locking, and then tightening the screw 80 to fix the rotor element 20 on the cover plate 40, i.e., the rotor element 20 is in the second state, so as to fix the antenna body 10, realizing the anti-loose structure of the antenna body 10 connection.

[0054] The radio frequency interface fixing structure can be applied to the technical field of unmanned aerial vehicles.

[0055] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
