[0003] However, existing drones generally use an integrated structure fixture to fix the fixture to the drone, and the fixture can only be adapted to specific types of sensors and lacks versatility. Utility Model Content

[0004] In view of the above problems in the prior art, the purpose of the utility model is to provide a sensor fixing fixture for drone mounting, which can realize rapid disassembly and assembly of the drone and the fixture body through a plug-in mechanism, and is convenient for selecting an appropriate fixture body structure according to the structure of the sensor.

[0005] A sensor fixing fixture for mounting on an unmanned aerial vehicle comprises a fixture body, which is detachably connected to the unmanned aerial vehicle via a plug-in mechanism, and is used to clamp a required sensor and suspend it below the unmanned aerial vehicle; the fixture body comprises a bracket, a connecting rod and a clamping claw, and two relatively distributed sliders are sleeved on the connecting rod, and the slider is connected to the bracket via a front swing rod, and the slider is connected to the clamping claw via a rear swing rod, and the clamping claw slides on the bracket; the connecting rod is driven by a self-locking motor to move up and down, and the two clamping claws slide on the bracket by relying on the cooperation between the front swing rod, the rear swing rod and the slider to adjust the relative distance between the two clamping claws, so as to realize the taking and placing of the sensor.

[0006] Preferably, the bracket includes a cavity for installing a self-locking motor and a fixing sleeve for connecting the clamping claw. The bracket is provided with two fixing sleeves, which are symmetrically arranged, and each fixing sleeve is connected to a clamping claw.

[0007] Preferably, the clamping claw comprises a cross bar sleeved with the fixing sleeve of the bracket and a clamping seat for abutting the sensor, and the end surface of the clamping seat for abutting the sensor is square or circular.

[0008] Preferably, the connecting rod is connected to the self-locking motor through a screw, the nut of the screw is embedded and installed on the connecting rod, the screw shaft of the screw is sleeved with the nut, and one end of the screw shaft is connected to the self-locking motor through a coupling.

[0009] Preferably, an insertion rod is connected to the top of the bracket, and the insertion rod is used in conjunction with a plug-in mechanism installed on the drone to hang the bracket under the drone. The plug-in mechanism includes an interface seat, a spring, and an abutment block.

[0024] Embodiment 1

[0025] like Figures 1 to 7 As shown, a sensor fixing fixture for drone mounting includes a fixture body 2, which is detachably connected to the drone 1 through a plug-in mechanism. The fixture body 2 is used to clamp the required sensor and suspend it under the drone 1.

[0026] like Figures 2 to 5 As shown, the clamp body 2 includes a bracket 201, a connecting rod 204 and a clamping claw 207. The top of the bracket 201 is connected with an insertion rod 3, and the insertion rod 3 cooperates with the plug-in mechanism installed on the drone 1 to make the bracket 201 suspended below the drone 1.

[0027] The bracket 201 includes a cavity for installing the self-locking motor 202 and a fixing sleeve for connecting the clamping claw 207. The bracket 201 is provided with two fixing sleeves, which are symmetrically arranged, and each fixing sleeve is connected with a clamping claw 207.

[0028] The clamping jaw 207 includes a crossbar that is sleeved with the fixing sleeve of the bracket 201 and a clamping seat 208 for abutting against the sensor, wherein the crossbar is sleeved with the fixing sleeve and mounted on the bracket 201, and the bracket 201 provides support. The end surface structure of the clamping seat 208 for abutting against the sensor is adapted to the structure of the sensor. According to the shape of the sensor, the end surface of the clamping seat 208 is either square or round. Figure 2 The end surface of the clamping seat 208 in the clamp body 2 is circular. Figure 8 The end surface of the clamping seat 208 in the clamp body 2 is shown to be square.

[0029] Please refer to Figure 6 , two relatively distributed sliders 206 are sleeved on the connecting rod 204, the slider 206 is connected to the bracket 201 through the front swing rod 205, and is connected to the clamp 207 through the rear swing rod 209, and the connecting rod 204 is connected to the self-locking motor 202 through the lead screw 203. Specifically, the nut of the lead screw 203 is embedded and installed on the connecting rod 204, the lead screw shaft of the lead screw 203 is sleeved with the nut, and one end of the lead screw shaft is connected to the self-locking motor 202 through a coupling. Since the self-locking motor 202 has a self-locking function, during the flight of the drone 1, even if it encounters vibration or airflow impact, the clamp body 2 can firmly fix the sensor to prevent the sensor from loosening or falling off, and ensure that the fixed posture of the sensor remains unchanged.

[0030] The connecting rod 204 is driven by the self-locking motor 202 to move up and down. Through the adjustment of the front swing arm 205 and the rear swing arm 209, the clamping jaws 207 slide in the fixed sleeve of the bracket 201 to adjust the relative distance between the two clamping jaws 207, thereby realizing the grasping action of the two clamping jaws 207, thereby completing the pick-up and placement operation of the sensor.

[0031] Embodiment 2

[0032] like Figure 7 As shown, the structure of this embodiment is basically the same as that of the first embodiment, except that the plug-in mechanism of this embodiment includes an interface seat 301, a spring 302, an abutment block 303, a cover 304 and a bolt 305. The interface seat 301 is mounted on the drone 1, and a through slot is provided inside the interface seat 301 for the insertion rod 3 to be inserted.

[0033] The abutment block 303 is disposed in the through slot, one end of the abutment block 303 is connected to the spring 302, the other end of the spring 302 is connected to the cover 304, and the cover 304 is detachably connected to the interface seat 301 through a bolt 305. The end of the abutment block 303 facing the through slot is conical, and a clamping hole matching the abutment block 303 is provided at a corresponding position of the insertion rod 3.

[0034] When the insertion rod 3 is inserted into the through slot, the abutment block 303 is squeezed and compresses the spring 302. When the conical structure of the abutment block 303 falls into the clamping hole on the insertion rod 3, the spring 302 is reset and the abutment block 303 abuts and fixes the insertion rod 3, thereby realizing the connection between the clamp body 2 and the drone 1.

[0035] It should be noted that there are multiple abutment blocks 303, and the number of springs 302 and covers 304 corresponds to the number of abutment blocks 303. The multiple abutment blocks 303 work together to enable the clamp body 2 to be stably suspended on the drone 1, and the insertion rod 3 can be pulled out of the interface seat 301 by the manpower of the staff.

[0036] Working principle: When using the sensor fixing fixture for drone mounting, the end face shape of the clamping seat 208 is selected according to the required sensor structure, and then the self-locking motor 202 is started. The self-locking motor 202 drives the lead screw 203 to drive the connecting rod 204 to move, and the front swing bar 205, the rear swing bar 209 and the slider 206 are adjusted to move the clamping claw 207 along the fixing sleeve of the bracket 201, so that the two clamping seats 208 are close to each other until the sensor is clamped and fixed, and then the clamp body 2 is connected to the drone 1 through the structural design of the insertion rod 3 and the plug-in mechanism, so that the clamp body 2 drives the sensor to be hung on the drone 1, so that the drone 1 can perform corresponding marine environment monitoring, marine resource exploration, fishery management, maritime search and rescue and other tasks.

[0037] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
