DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0024] This embodiment provides a police transmitter gap elimination structure, which is mainly used when a police transmitter is mounted on a drone for use. The recoil generated by the launch of the projectile impacts the installation hinge of the master control system, causing a gap between the installation hinge of the master control system and the loading body, thereby causing the contact probe to have poor contact. This embodiment eliminates the gap between the installation hinge of the master control system and the loading body by setting a hinge gap elimination structure between the installation hinge of the master control system and the loading body, using the interference fit of the eccentric cam of the hinge gap elimination structure and the arc base, and by the conical surface contact and thread tightening of the hinge clamping structure of the installation hinge of the master control system, thereby eliminating the gap in the vertical direction between the installation hinge of the master control system and the loading body.
[0025] like Figure 1 As shown, Figure 1The overall assembly diagram of the embodiment of the present invention. The gap elimination structure of the police transmitter in this embodiment includes a master control system installation hinge 1, a loading body 2, a hinge structure 3, a hinge gap elimination structure 4, a hinge pressing structure 5 and a photoelectric module 6. The master control system installation hinge 1 is movably connected to the loading body 2 at one end through the hinge structure 3, and the other opposite end is fixedly connected through the hinge pressing structure 5.
[0026] The hinge gap elimination structure 4 is installed between the main control system installation hinge 1 and the loading body 2 at one end of the hinge structure 3 .
[0027] The photoelectric module 6 is installed at the lower center of the loading body 2 .
[0028] like Figure 2 As shown, Figure 2 The main control system installation hinge 1 is composed of a main control board housing 11 and a main control board mounting seat 12. The main control board housing 11 is mounted on the main control board mounting seat 12 by screws. The main control board housing 11 and the main control board mounting seat 12 are internally installed with a main control board 13 and a contact probe 14 installed on the main control board (see FIG. Figure 3 ), the main control board 13 integrates the control program and commands of the transmitter, and the contact probe 11 with a contact probe holder is welded on the main control board.
[0029] The loading body 2 is composed of a ballistic mounting seat 21 and a ballistic 22. The ballistic 22 is mounted below the ballistic mounting seat 21 by screws, and the projectile body 23 is placed inside the ballistic mounting seat 21 (see Figure 4 ).
[0030] The hinge structure 3 is composed of two parts, which are respectively composed of a left guide shaft 31, a hinge 32 and a right guide shaft 33. The left guide shaft 31 and the right guide shaft 33 are installed on the side of the ballistic mounting seat 21 by screws, and the hinge 32 is installed on the side of the main control board mounting seat 12 by screws (see Figure 5 ).
[0031] The hinge gap elimination structure 4 is installed between the two hinge structures 3, and is composed of a guide groove 41, an eccentric cam 42 and an arc base 43. The guide groove 41 is installed on the side of the main control board mounting seat 12 by screws, the eccentric cam 42 is installed on the guide groove 41 through its own rotating shaft, and the arc base 43 is installed on the ballistic mounting seat 21 by screws (see Figure 5 ).
[0032] The eccentric cam 42 and the arc base 43 are used for interference fit with a tolerance of ≥0.1mm when the master control system installation hinge 1 and the ballistic mounting seat 21 are closed, so that the master control system installation hinge 1 and the ballistic mounting seat 21 are tightly closed to eliminate the gap at the ends of the hinge structure 3.
[0033] There are two hinge clamping structures 5, which are respectively composed of a countersunk screw 51, a flat knob 52, a conical fastening sleeve 53, a conical upper flange seat 54, a conical lower flange seat 55, a spring 56 and a non-standard stud 57. The flat knob 52 and the conical fastening sleeve 53 are firmly installed with the countersunk screw 51 through the threaded holes with screw glue. The conical upper flange seat 54 is installed on the side of the main control panel mounting seat 12. The conical lower flange seat 55 is provided with an axial threaded hole so that the countersunk screw 51 is threadedly connected and passed through. The spring 56 is sleeved on the countersunk screw 51, one end of which contacts with the conical lower flange seat 55, and the other end contacts with the non-standard stud 57 firmly installed on the end of the countersunk screw 51 through the screw glue. The conical lower flange seat 55 is installed on the ballistic mounting seat 21 by screws (see Figure 6 ).
[0034] A conical surface is arranged inside the conical fastening sleeve 53 in the hinge clamping structure 5. When the master control system is installed with the hinge 1 closed, the conical fastening sleeve 53 can be screwed in by turning the flat knob 52, so that it contacts and is pressed against the conical surfaces of the conical upper flange seat 54 and the conical lower flange seat 55, so as to eliminate the gap between the master control system installation hinge 1 and the ballistic mounting seat 21. At the same time, the spring 56 is used to prevent the countersunk screw 51 from loosening, and the non-standard stud 57 is used to limit the countersunk screw 51 to prevent the countersunk screw 51 from falling off when being screwed out.
[0035] In addition, in the present embodiment, the main control board mounting seat 12 is provided with a boss on the end face, and the ballistic mounting seat 21 is provided with a groove on the end face. When the conical fastening sleeve 53 is screwed in and tightened, the main control board mounting seat 12 and the ballistic mounting seat 21 can be effectively prevented from translational misalignment. At the same time, a conical blind hole is provided on the side of the ballistic mounting seat 21 for guiding the countersunk screw 51 in the hinge clamping structure 5.
[0036] In this embodiment, the master control panel mounting seat 12, the hinge 32 and the ballistic mounting seat 21 are all provided with wire grooves for routing the master control system circuit. The hinge 32 is also designed with a limiting boss to limit the flipping angle of the master control system mounting hinge 1 to a certain angle.
[0037] To sum up, the present invention achieves complete elimination of the gap between the installation hinge of the master control system and the loading body through the conical surface contact and thread tightening adopted by the hinge clamping structure and the eccentric cam interference fit adopted by the hinge gap elimination structure. When the police transmitter is mounted on the drone to perform a mission, the contact probe maintains good contact with the projectile body, which solves the problem that the traditional closed hinges using buckles, sliding pins, etc. have gaps. Especially after the first few rounds of bullets are fired, the gap between the installation hinge of the master control system and the loading body increases due to the recoil of the bullet, resulting in poor contact of the contact probe. This reduces the probability of failure to fire when the police transmitter is fired, improves the quality and efficiency of mission execution, and reduces unnecessary losses.
[0038] The specific implementation methods of the invention are described in detail above, but they are only examples, and the present invention is not limited to the specific implementation methods described above. For those skilled in the art, any equivalent modification or substitution of the invention is also within the scope of the present invention. Therefore, the equalization, modification, improvement, etc. made without departing from the spirit and principle of the present invention should be included in the scope of the present invention.
