For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] In the first embodiment, if Figure 1-4 As shown, a UAV load mounting platform comprises a first rectangular base plate 1, a second rectangular base plate 2 and a third rectangular base plate 3 which are arranged parallel to each other from top to bottom; the top ends of the two connecting plates are symmetrically fixedly connected to the left and right parts of the lower surface of the first rectangular base plate 1, and the bottom ends of the two connecting plates are symmetrically fixedly connected to the left and right parts of the upper surface of the second rectangular base plate 2; a plurality of positioning holes are arranged equidistantly in the vertical direction on the surface of the connecting plate; a linear bearing is respectively provided at the four corners of the second rectangular base plate 2, and a cylindrical guide rail 6 is provided through the four linear bearings; the top ends of the two cylindrical guide rails 6 which are opposite to each other front and back are respectively fixed to the two ends of the connecting rod 5; the upper surfaces of the two connecting rods 5 are respectively provided with ball head plungers, which cooperate with the positioning holes on the connecting plates which are closest to them to limit and fix them; the bottom ends of the four cylindrical guide rails 6 are respectively fixedly connected to the four corners of the upper surface of the third rectangular base plate 3; the lower surface of the third rectangular base plate 3 is provided with two fixing clips 7 which are symmetrically arranged on the left and right sides, and the two fixing clips 7 fix the detachable load fixing plate 4.

[0034] In this embodiment, the first rectangular substrate 1 on the top of the load platform is first fixed to the bottom of the drone body 9, and then different types of drone loads, such as video monitoring modules, thermal infrared monitoring modules, environmental monitoring sampling modules, etc. are pre-fixed on the load fixing plate 4. When the load needs to be installed, it is only necessary to install the load fixing plate 4 to the lower surface of the third rectangular substrate 3, and use two fixing clips 7 to fix the load fixing plate 4 to complete the installation of the load module. Further, according to the size and volume of the load module, as well as the application conditions of the load module, for example, the load module is too close to the landing gear 90 after installation, which may damage the load equipment when the drone lands, or the landing gear 90 and the load module are not in a good position, affecting the working effect of the load module, etc., the height of the load fixing plate 4 is adjusted through the load platform to finally achieve the setting height adjustment of the load module.

[0035] Specifically, the operator pushes the third rectangular substrate 3 to move. Since the third rectangular substrate 3 is connected to the bottom of the cylindrical guide rail 6, the third rectangular substrate 3 can drive the cylindrical guide rail 6 to move upward, and the connecting rod 5 at the top of the cylindrical guide rail 6 moves upward at the same time. At this time, the ball head plunger 51 on the connecting rod 5 moves upward one by one along the multiple positioning holes 12 on the corresponding connecting plate 11. When the specified height is reached, the ball head of the ball head plunger 51 extends into the corresponding positioning hole 12 to form a clamping effect. At this time, due to the simultaneous action of the left and right ball head plungers 51, the relative position of the connecting rod 5 on the connecting plate 11 is guaranteed to be stable, thereby achieving the third rectangular substrate 3 being set at the corresponding height.

[0036] In this embodiment, all components of the drone load mounting platform are made of lightweight materials to reduce the weight of the entire platform as much as possible while ensuring stable performance.

[0037] In this embodiment, the ball plunger 51 uses a ball plunger 51 with a large diameter ball head, which ensures the stability of the clamping position of the ball plunger 51.

[0038] In another embodiment, Figure 2-3 As shown, the fixing clamp 7 includes a U-shaped groove 71 and a handle 72; the U-shaped groove 71 is fixedly arranged on the lower surface of the third rectangular substrate 3, and a rotating shaft 73 is arranged in the U-shaped groove 71; the handle 72 includes a rotating part, one end of the rotating part is connected to the pressing part, and the other end of the rotating part is connected to the supporting part; the rotating shaft 73 passes through the rotating part, and a reset spring 74 is arranged between the pressing part and the bottom of the U-shaped groove 71.

[0039] When the user presses down the pressing portion of the handle 72, the rotating portion of the handle 72 rotates around the rotating shaft 73. At this time, the pressing portion approaches the third rectangular substrate 3, and the reset spring 74 arranged between the pressing portion and the U-shaped groove 71 is compressed. At the same time, the supporting portion of the handle 72 moves in the direction away from the third rectangular substrate 3, and the entire fixing clamp 7 opens, so that the load fixing plate 4 can be put in and taken out. After the load fixing plate 4 is put in and taken out, the operator releases the pressing portion of the handle 72. At this time, the handle 72 is reset under the action of the reset spring 74, and the supporting portion of the handle 72 moves in the direction close to the third rectangular substrate 3, and the entire fixing clamp 7 returns to the closed state.

[0040] In this embodiment, triangular protrusions are provided on the upper surface of the pressing portion of the handle 72 and the side wall of the U-shaped groove 71 relative to the pressing portion, and the two ends of the reset spring 74 are respectively connected to the inclined surfaces of the two triangular protrusions. The inclined setting of the reset spring 74 improves the smoothness of pressing down and resetting the handle 72.

[0041] In another embodiment, Figure 3 As shown, the lower surface of the pressing portion is provided with a protrusion for preventing slipping during pressing.

[0042] In another embodiment, Figure 2-3 As shown, both left and right ends of the load fixing plate 4 are provided with through holes, which are matched and fixed with the raised supporting parts.

[0043] In this embodiment, rectangular through holes are provided at both ends of the load fixing plate 4. The supporting portion of the handle 72 faces the side of the load fixing plate 4 and is provided with a rectangular protrusion that matches the shape of the rectangular through hole on the load fixing plate 4. When the supporting portion of the handle 72 is pressed down onto the load fixing plate 4, the rectangular protrusion on the supporting portion of the handle 72 enters into the rectangular through hole on the load fixing plate 4, thereby achieving fixed limiting of the load fixing plate 4.

[0044] In another embodiment, Figure 1 and Figure 4 As shown, a notch 8 for placing connecting cables is provided at the middle of the front end of the first rectangular substrate 1 , the middle of the front end of the second rectangular substrate 2 , and the middle of the front end of the third rectangular substrate 3 , and the three notches 8 are arranged in a straight line.

[0045] In this embodiment, when the load on the load fixing plate 4 needs to be electrically connected to the drone body 9 , the connecting cable enters the drone body 9 through three notches 8 arranged in a straight line.

[0046] In another embodiment, Figure 1 As shown, a mounting beam for fixing the UAV load is provided on the lower surface of the load fixing plate 4, and the load can be fixed on the mounting beam.

[0047] In another embodiment, Figure 1 and Figure 4 As shown, the first rectangular substrate 1 is provided with a mounting through hole for fixing to the drone body 9 .

[0048] In another embodiment, Figure 1-2 As shown, five positioning holes 12 are provided on the same connecting plate 11. In this embodiment, the provision of the five positioning holes 12 ensures five gears for adjusting the height of the load fixing plate 4.

[0049] Further, such as Figure 1 As shown, a plunger mounting seat is provided on the upper surface of the connecting rod 5, and a ball plunger 51 is arranged on the plunger mounting seat.

[0050] Further, such as Figure 1 As shown, the load securing plate 4 is rectangular in shape.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
