Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a reinforcement structure for aerial photogrammetry, including a reinforcement platform 1 for fixing a drone and a camera. Figure 1 In this context, A represents a drone. Figure 1In this configuration, B represents a camera. The mounting platform 1 is fixed to the drone A as a single unit, and the camera B is assembled with the mounting platform 1. A cover plate 5 is connected to the top of one side of the mounting platform 1 via a hinge. A limit block 51 is fixed to the inner surface of the cover plate 5. The cover plate 5 is rotatably connected to the mounting platform 1 and can be flipped to facilitate the assembly of the camera B on the mounting platform 1. The cover plate 5 contacts the top surface of the camera B, achieving the effect of limiting the camera B. The limit block 51 is fixed to the cover plate 5 by welding and serves to limit the movement of the moving block 8. The limiting assembly includes a stabilizing block 71 fixedly connected to the inner wall of the mounting platform 1, a positioning rod 72 penetrating the stabilizing block 71, a contraction spring 75 sleeved on the outside of the positioning rod 72, a movable block 73, and a moving column 4 penetrating the bottom surface of the mounting platform 1 and connected to the movable block 73. An abutment plate 74 is fixedly connected to the side of the movable block 73. The stabilizing block 71 is welded to the mounting platform 1 and the positioning rod 72. The movable block 73 moves axially along the positioning rod 72. The movable block 73 can compress the compression spring 75, and the abutment plate 74 acts to hold the mounting block 63 in place, preventing it from becoming loose. The anti-skew assembly includes a limiting post 61 on the inner wall of the vertically reinforcing platform 1, a compression spring 62 sleeved on the outside of the limiting post 61, and a mounting block 63. The mounting block 63 is fixed to the housing of the camera B using screws and adhesives to form an integral structure. The mounting block 63 and the limiting post 61 are separate structures. When the camera B is installed, the mounting block 63... The mounting block 63, fitted onto the outside of the limiting post 61, can compress the spring 62, which generates elastic force. The bottom end of the moving block 8 is connected to the top surface of the movable block 73. The top end of the moving block 8 is embedded between the limiting block 51 and the cover plate 5. The top end of the moving block 8 is limited, and the movable block 73 and the abutment plate 74 remain stable, thereby keeping the mounting block 63 held by the abutment plate 74 stable. Under the clamping action of the abutment plate 74 and the compression spring 62, the mounting block 63 is in a stable state.

[0028] In this embodiment, the reinforcement platform 1 includes a first side plate a, a bottom plate b, and a second side plate c. The cover plate 5 and the stabilizing block 71 are connected to the first side plate a. The limiting column 61 is perpendicular to the second side plate c. The movable column 4 is slidably connected to the bottom plate b. A rubber pad 52 is adhered to the surface of the cover plate 5 facing the bottom plate. The rubber pad 52 is made of rubber material and can absorb and buffer vibration force to reduce the vibration of the camera B.

[0029] In this embodiment, a rubber sleeve 631 is bonded to the inner surface of the mounting block 63, and the limiting post 61 passes through the rubber sleeve 631. The two ends of the compression spring 62 are respectively connected to the reinforcement platform 1 and the mounting block 63. The rubber sleeve 631 can absorb and buffer the vibration force, reduce the vibration of the mounting block 63, and thus keep the camera B stable.

[0030] In this embodiment, the abutment plate 74 has a right-angle structure. A groove d is provided on the side surface of the abutment plate 74 away from the movable block 73. The limiting post 61 cooperates with the groove d. The abutment plate 74 can be fitted on the outside of the limiting post 61 and abut against the mounting block 63.

[0031] In this embodiment, the movable block 8 is perpendicular to the movable block 73. The top of the movable block 8 is a right-angle structure. A rectangular movable groove is opened on the inner surface of the cover plate 5. A groove is formed between the limiting block 51 and the cover plate 5. The right-angle end of the limiting block 51 cooperates with the groove. The top of the movable block 8 is embedded in the position between the limiting block 51 and the cover plate 5. The top of the movable block 8 is limited, and the movable block 73 and the abutment plate 74 remain stable.

[0032] In this embodiment, a windshield 2 is fixed to the surface of the cover plate 5 by screws. A semi-elliptical diverter block 21 is bonded to the surface of the windshield 2. A triangular bracket-shaped flow guide 3 is fixed to the side of the reinforcement platform 1. The inclined surface of the flow guide 3 is a curved streamline shape. The windshield 2 and the flow guide 3 play the role of reducing wind force. The diverter block 21 is streamlined. When the drone A is flying, the airflow facing the camera B flows along the surface of the windshield 2 and the flow guide 3, reducing the wind force on the camera B.

[0033] Working principle and usage process of this utility model:

[0034] When assembling camera B with mounting platform 1, camera B housing and mounting block 63 are pre-configured as an integral structure.

[0035] When the cover plate 5 is opened, the symmetrical moving columns 4 are moved relative to each other, the movable block 73 compresses the contracting spring 75, the top of the moving block 8 leaves the limiting block 51, and the abutting plate 74 leaves the limiting column 61.

[0036] Place camera B inside the reinforced platform 1, and mount block 63 on the outside of limiting post 61;

[0037] Close cover plate 5, cover plate 5 presses down on camera B;

[0038] Release the movable column 4, and under the elastic force of the contraction spring 75 and the outward movement, the movable column 4 and the movable block 73 move;

[0039] The top of the movable block 8 is embedded between the limiting block 51 and the cover plate 5, and the top of the movable block 8 is limited. The movable block 73 and the abutment plate 74 remain stable. The abutment plate 74 abuts against the mounting block 63. Under the clamping action of the abutment plate 74 and the compression spring 62, the mounting block 63 is in a stable state, so the camera B remains stable.

[0040] When drone A is flying, the airflow facing camera B flows along the surface of windshield 2 and deflector 3. Windshield 2 and deflector 3 guide the airflow and reduce the wind force, thus reducing the wind force on camera B.

[0041] In summary, this utility model features a reinforced bracket design that facilitates assembly and prevents tilting. With the coordinated action of the reinforcing platform 1, cover plate 5, moving block 8, limiting components, and anti-tilting components, the mounting block 63 fixed to the camera is constrained, preventing the camera from tilting or shaking. Furthermore, the camera can be easily removed by moving the moving column 4 and opening the cover plate 5, making the camera assembly process simple.

[0042] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
