Description

Technical Field

[0001] This utility model relates to the field of drone mounting bracket technology, specifically a multispectral camera bracket for drone mounting. Background Technology

[0002] A multispectral camera is an imaging device that simultaneously captures the reflected radiation energy of a target object through multiple specific wavelengths (usually beyond the visible light range). It is commonly used in agriculture, environmental monitoring, forestry surveys, geological exploration, and other fields. With the development of UAV technology, the method of data collection by using UAVs equipped with multispectral cameras has been widely adopted.

[0003] Many drones on the market do not come with multispectral cameras installed. Therefore, a drone extension mount has emerged on the market. The extension mount is similar to a clamp structure, which is tied and fixed to the outside of the drone body. The extension mount is equipped with studs for connecting and installing multispectral cameras (the multispectral camera has a bracket structure that is threaded to the studs on its outside), which can realize the convenient mounting of multispectral cameras.

[0004] However, in practical use, when a multispectral camera is mounted under a drone, the drone cannot land directly on the ground, otherwise the multispectral camera will be damaged by a collision with the ground. Based on this, a multispectral camera mount for drones is provided. Utility Model Content

[0005] The purpose of this invention is to provide a multispectral camera mount for drones in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multispectral camera mount for a drone, comprising a mount assembly consisting of a clamp mount, connecting ears, fastening bolts, extension connectors, and mounting studs. The connecting ears are integrally formed at both ends of the top of the clamp mount. The connecting ears are connected to the extension connectors via fastening bolts. The extension connectors provide an installation position for the multispectral camera above the drone. The mounting studs are fixed to the middle of the bottom of the clamp mount and provide an installation position for the multispectral camera below the drone. Side nut seats are symmetrically fixed on both sides of the outer wall of the clamp mount. The clamp mount is equipped with a foot assembly via the side nut seats. The foot assembly provides support for the drone and prevents the multispectral camera mounted below the drone from contacting the ground.

[0007] The support leg assembly includes a support unit and an adjustment and locking unit;

[0008] The support unit contacts the ground to allow space between the UAV and the ground for the placement of the multispectral camera;

[0009] The adjustment and locking unit is used to adjust and lock the support height of the support unit, thereby matching the different height bracket structures that come with the multispectral camera.

[0010] As a further embodiment of this utility model: the support unit includes a connecting cylinder, a connecting stud, a telescopic cylinder, a threaded sleeve, a lifting crossbeam, and connecting bolts;

[0011] The connecting stud is fixed to the top of the connecting cylinder column, and the connecting stud is threaded to the side nut seat;

[0012] The telescopic cylinder is slidably installed on the inner side of the connecting cylinder, the screw sleeve is fixed to the bottom of the telescopic cylinder, the landing crossbeam is attached to the bottom of the screw sleeve, and the connecting bolt passes through the landing crossbeam from the bottom and is threadedly connected and fixed to the screw sleeve, so as to realize the connection between the landing crossbeam and the screw sleeve.

[0013] Two symmetrical landing gears contact the ground to provide support for the placement of the drone.

[0014] As a further improvement of this utility model: the adjustment and locking unit includes a slot, an L-shaped locking block, and an N-shaped spring piece;

[0015] Multiple slots are evenly provided along the long side of the connecting cylinder. The L-shaped locking block is located on the inner side of the telescopic cylinder near the top and passes through the telescopic cylinder and engages with a slot. It is used to lock the relative position of the telescopic cylinder and the connecting cylinder. The L-shaped locking block retracts and pushes the telescopic cylinder to move, thereby adjusting the overall length of the connecting cylinder and the connecting stud.

[0016] The N-type spring clips are distributed between the bottom of the L-shaped locking block and the inner wall of the telescopic cylinder, and are used to provide thrust to the L-shaped locking block.

[0017] As a further embodiment of this utility model: the adjusting locking unit also includes a fixing ring, a reinforcing rod, a limiting ring, and a spring;

[0018] The fixing ring is fixed to the inner side of the telescopic cylinder near the top, and the reinforcing rod extends from the inside of the threaded sleeve into the inside of the telescopic cylinder and is close to the L-shaped locking block.

[0019] The limiting ring is fixed to the outside of the reinforcing rod and distributed between the threaded sleeve and the fixing ring. The spring is distributed between the limiting ring and the fixing ring and sleeved on the outside of the reinforcing rod. When the connecting bolt is threadedly connected to the threaded sleeve, it squeezes the reinforcing rod to move and inserts between the L-shaped locking block and the inner wall of the telescopic cylinder column to lock the L-shaped locking block.

[0020] As a further embodiment of this utility model: the inner diameter of the telescopic cylinder is larger than the inner diameter of the threaded sleeve, the outer diameter of the limiting ring matches the inner diameter of the telescopic cylinder, and the end of the L-shaped locking block that is close to the reinforcing rod has an arc surface structure.

[0021] As a further improvement of this utility model, the clamp bracket has straight grooves integrally formed on both sides below the side nut seat.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By setting up a support frame, when the multispectral camera is mounted under the drone, the two landing gears of the support frame contact the ground, which can effectively prevent the spectral camera from colliding with the ground and causing damage when the drone lands. This further expands the functionality of the support frame and makes it more flexible and convenient to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figures 1-3In this embodiment of the utility model, a multispectral camera bracket mounted on a drone includes a bracket assembly 1 consisting of a clamp bracket 101, connecting ears 102, fastening bolts 103, extension connectors 104, and mounting studs 105. The connecting ears 102 are integrally formed at both ends of the top of the clamp bracket 101. The connecting ears 102 are connected to the extension connectors 104 through the fastening bolts 103. The extension connectors 104 are used to provide an installation position for the multispectral camera above the drone. The mounting studs 105 are fixed to the middle of the bottom of the clamp bracket 101. The mounting studs 105 are used to provide an installation position for the multispectral camera below the drone. Side nut seats 106 are symmetrically fixed on both sides of the outer wall of the clamp bracket 101. The clamp bracket 101 is equipped with a foot assembly 2 through the side nut seats 106. The foot assembly 2 is used to provide support for the drone and prevent the multispectral camera installed below the drone from contacting the ground.

[0030] The support leg assembly 2 includes a support unit and an adjustment locking unit;

[0031] The support unit contacts the ground to allow space between the drone and the ground for the placement of the multispectral camera;

[0032] The adjustment and locking unit is used to adjust and lock the support height of the support unit, so as to match the different height bracket structures of the multispectral camera;

[0033] The support unit includes a connecting cylinder 201, a connecting stud 202, a telescopic cylinder 204, a threaded sleeve 205, a lifting crossbeam 211, and a connecting bolt 212;

[0034] The connecting stud 202 is fixed to the top of the connecting cylinder 201, and the connecting stud 202 is threaded to the side nut seat 106;

[0035] The telescopic column 204 is slidably installed inside the connecting column 201, the threaded sleeve 205 is fixed to the bottom of the telescopic column 204, the landing frame 211 is attached to the bottom of the threaded sleeve 205, and the connecting bolt 212 passes through the bottom of the landing frame 211 and is threadedly connected and fixed to the threaded sleeve 205, so as to realize the connection between the landing frame 211 and the threaded sleeve 205;

[0036] Two symmetrical landing crossbars 211 contact the ground to provide support for the placement of the drone;

[0037] The adjusting locking unit includes a slot 203, an L-shaped locking block 207, and an N-type spring piece 208;

[0038] Multiple slots 203 are evenly provided along the long side of the connecting cylinder 201. L-shaped blocks 207 are located on the inner side of the telescopic cylinder 204 near the top and pass through the telescopic cylinder 204 and engage with a slot 203. This is used to lock the relative position of the telescopic cylinder 204 and the connecting cylinder 201. The L-shaped blocks 207 retract and push the telescopic cylinder 204 to move, thereby adjusting the overall length of the connecting cylinder 201 and the connecting stud 202.

[0039] N-type spring clips 208 are distributed between the bottom of the L-shaped locking block 207 and the inner wall of the telescopic cylinder 204, and are used to provide thrust to the L-shaped locking block 207.

[0040] In this embodiment, the camera bracket is used as follows:

[0041] First, the two connecting cylinders 201 can be threaded to the two side nut seats 106 respectively through the connecting studs 202. Then, by pressing the two connecting cylinders 201 closer to each other, the two connecting ears 202 on the clamp bracket 101 can be moved away from each other and the distance between them can be increased. This makes it easier for the clamp bracket 101 to be fitted onto the drone body. After the clamp bracket 101 is fitted onto the drone body, the pressure on the connecting cylinders 201 is released. At this time, the clamp bracket 101 returns to its original position and fits onto the drone body under the action of its own material elasticity. (It should be noted that the shape of the clamp bracket 101 is set according to the shape of the drone body of different models, and when the clamp bracket 101 is installed, the connecting ears 202 are located on top of the drone.)

[0042] Then, other components are selectively installed based on the installation location of the multispectral camera:

[0043] If the multispectral camera needs to be mounted on top of the drone, an extension connector 104 can be installed between the two connecting ears 202, and the extension connector 104 can be connected and fixed to the connecting ears 202 by fastening bolts 103. Then, the multispectral camera can be connected to the extension connector 104 (it should be noted that the top of the extension connector 104 is provided with a stud for the multispectral camera to be connected). This can prevent the multispectral camera from being too close to the drone's propellers. After the multispectral camera is installed, the connecting cylinder 201 can be removed. In this case, the support leg assembly 2 is not required.

[0044] If the multispectral camera needs to be installed under the drone, it can be directly connected to the mounting stud 105. Then, the telescopic cylinder 204 can be adjusted according to the downward extension height of the multispectral camera: by pressing the L-shaped locking block 207 to retract inward (the N-type spring 208 further retracts), the L-shaped locking block 207 is released from the slot 203. At the same time, an upward or downward pushing force is applied to the L-shaped locking block 207, causing the telescopic cylinder 204 to move relative to the fixed cylinder 201. When the L-shaped locking block 207 is aligned with another slot 203, the L-shaped locking block 207 can pop out under the elastic force of the N-type spring 208 and engage with this slot 203. By repeating this operation, the overall length of the telescopic cylinder 204 and the fixed cylinder 201 can be adjusted.

[0045] When the bottom of the threaded sleeve 205 is lower than the bottom of the multispectral camera, the landing gear 211 can be removed and fitted to the bottom of the threaded sleeve 205. Then, the connecting bolt 212 is threaded through the landing gear 211 and connected to the threaded sleeve 205. (It should be noted that the landing gear 211 has mounting holes for the connecting bolt 212 to pass through.)

[0046] In subsequent use, the two landing gears 211 make contact with the ground, which can effectively prevent the spectral camera from being damaged by contact with the ground when the drone lands.

[0047] Please refer to this carefully. Figures 2-3 The adjusting locking unit also includes a fixing ring 206, a reinforcing rod 209, a limiting ring 210, and a spring 213;

[0048] The fixing ring 206 is fixed to the inner side of the telescopic cylinder 204 near the top, and the reinforcing rod 209 extends from the inside of the threaded sleeve 205 into the inside of the telescopic cylinder 204 and is close to the L-shaped locking block 207.

[0049] The limiting ring 210 is fixed to the outside of the reinforcing rod 209 and distributed between the threaded sleeve 205 and the fixing ring 206. The spring 213 is distributed between the limiting ring 210 and the fixing ring 206 and sleeved on the outside of the reinforcing rod 209. When the connecting bolt 212 is threadedly connected to the threaded sleeve 205, it presses the reinforcing rod 209 to move and insert it between the L-shaped locking block 207 and the inner wall of the telescopic cylinder column 204 to lock the L-shaped locking block 207.

[0050] The inner diameter of the telescopic cylinder 204 is larger than the inner diameter of the threaded sleeve 205. The outer diameter of the limiting ring 210 matches the inner diameter of the telescopic cylinder 204. The L-shaped locking block 207 and the end of the reinforcing rod 209 that are close to each other have an arc surface structure.

[0051] In this embodiment: when the connecting bolt 212 is not threadedly connected to the threaded sleeve 205, the reinforcing rod 209 does not contact the L-shaped locking block 207, that is, it does not affect the pressing and retracting operation of the L-shaped locking block 207, so that the telescopic cylinder 204 can be adjusted smoothly.

[0052] When the connecting bolt 212 is threadedly connected to the sleeve 205 and tightened, the connecting bolt 212 contacts the reinforcing rod 209 and presses the reinforcing rod 209 upward, causing the top of the reinforcing rod 209 to move and insert between the L-shaped locking block 207 and the inner wall of the telescopic cylinder 204. At this time, the L-shaped locking block 207 cannot retract, thereby reinforcing and fixing the relative position of the telescopic cylinder 204 and the fixed cylinder 201. This effectively prevents the telescopic cylinder 204 and the fixed cylinder 201 from loosening or retracting due to vibration during the take-off and landing of the UAV, further improving the stability of the support assembly 2.

[0053] Please refer to this carefully. Figures 1-2 The clamp bracket 101 has straight grooves 107 integrally formed on both sides below the side nut seat 106.

[0054] In this embodiment: the straight groove 107 provides good deformation elasticity to this part of the clamp bracket 101, enabling the clamp bracket 101 to better deform, expand, and reset, thus facilitating the installation of the clamp bracket 101 with the UAV fuselage.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
