Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary components for UAV mapping instruments, specifically to a fixed device for UAV mapping instruments. Background Technology

[0002] Unmanned aerial vehicle (UAV) surveying refers to the use of surveying instruments mounted on UAVs to take high-precision, high-efficiency photographs and measurements of target areas. Compared to traditional surveying methods, UAV surveying offers advantages such as flexibility, efficiency, safety, and low cost. It can easily handle complex terrain and environments, providing more accurate and comprehensive geographic information, and significantly reduce labor costs while improving work efficiency.

[0003] Existing surveying drones have a fixed device for securing the surveying instrument to the drone. Securing the surveying instrument to this device allows for its installation on the drone. However, existing surveying instrument fixing devices rely on traditional screw-press fastening technology, requiring tools to tighten or loosen the bolts before the surveying instrument can be detached from the device, making the process of attaching and detaching the surveying instrument from the drone rather cumbersome.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the above description of this utility model, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0031] Please see Figure 1-4 This utility model provides a technical solution: a mapping instrument fixing device for UAV mapping, including a base frame 1, a tray 2, a first clamping part 3, a first connecting part 31, and a connecting part 4. The tray 2 is located above the base frame 1. There are two first clamping parts 3, which are respectively disposed on the left and right sides of the tray 2. The first clamping parts 3 are slidably connected to the base frame 1. There are two first connecting parts 31, which are respectively disposed on the left and right sides of the tray 2. One end of the first connecting part 31 is hinged to the tray 2, and the other end is hinged to the first clamping part 3. The connecting part 4 is used to fix and connect the base frame 1 and the UAV.

[0032] When the UAV surveying instrument fixing device described in this utility model is in its initial state, the base frame 1 is fixedly connected to the UAV through the connecting part 4.

[0033] When installing a surveying instrument on the UAV surveying instrument fixing device described in this utility model, the tray 2 is lifted to a certain distance from the base frame 1, and then the surveying instrument is placed in the tray 2. The tray 2 and the surveying instrument move downward under the action of gravity, and the tray 2 drives one end of the first connecting member 31 to rotate downward. Since one end of the first connecting member 31 is hinged to the tray 2 and the other end is hinged to the first clamping part 3, during the downward rotation of one end of both first connecting members 31, the two first connecting members 31 drive the two first clamping parts 3 to slide simultaneously from the left and right sides of the tray 2 toward the tray 2. Until both first clamping parts 3 abut against the side of the surveying instrument, the first clamping parts 3 stop sliding, the one end of the first connecting member 31 stops rotating downward, and the tray 2 stops descending. At this point, the surveying instrument can be clamped and fixed in the middle by the two first clamping parts 3, and can then be clamped and installed on the drone. When removing the surveying instrument from the drone surveying instrument fixing device of this utility model, the tray 2 is lifted, and the tray 2 drives one end of the first connecting member 31 to rotate upward. Since one end of the first connecting member 31 is hinged to the tray 2 and the other end is hinged to the first clamping part 3, as both ends of the two connecting members rotate upward, the two first connecting members 31 drive the two first clamping parts 3 to slide simultaneously from the left and right sides of the tray 2 away from the tray 2. Until both first clamping parts 3 are disengaged from the side of the surveying instrument, the tray 2 is lifted and the first clamping parts 3 stop sliding, and the one end of the first connecting member 31 stops rotating downward. At this point, the surveying instrument can be removed from the tray 2.

[0034] By placing the surveying instrument on tray 2, the surveying instrument can be installed on the drone surveying instrument fixing device described in this utility model. By lifting tray 2 upwards a certain distance, the surveying instrument can be removed from the drone surveying instrument fixing device described in this utility model. The surveying instrument can be installed and removed from the drone surveying instrument fixing device described in this utility model without the need to use tools to tighten or loosen the bolts, which makes it more convenient to install and remove the surveying instrument on the drone.

[0035] In this embodiment, the first clamping part 3 includes a first vertical plate 37, a first sliding rod 34, a first baffle 32, a first clamping block 35, and a first spring 33. The lower end of the first vertical plate 37 is slidably connected to the base frame 1. The first sliding rod 34 is slidably connected to the first vertical plate 37. The first baffle 32 is fixed to the end of the first sliding rod 34 away from the tray 2. The first clamping block 35 is fixed to the end of the first sliding rod 34 near the tray 2. The first spring 33 is sleeved on the first sliding rod 34. One end of the first spring 33 is connected to the first baffle 32, and the other end is connected to the first vertical plate 37.

[0036] When installing the surveying instrument on the UAV surveying instrument fixing device of this utility model, after lifting the tray 2 to a certain distance from the base frame 1, the surveying instrument is placed on the tray 2. The two first vertical plates 37 slide towards the tray 2 under the action of the tray 2 and the two first connecting pieces 31. After the two first clamping blocks 35 abut against the two sides of the surveying instrument, the two first sliding rods 34 slide away from the tray 2. The first sliding rods 34 drive the first baffle 32 away from the tray 2 and stretch the first spring 33. At this time, the left and right sides of the surveying instrument can be clamped. With this structure, the surveying instrument can be clamped and fixed in the middle by the two first clamping parts 3. When removing the surveying instrument from the UAV surveying instrument fixing device of this utility model, the tray 2 is lifted, and the two first vertical plates 37 slide away from the tray 2 under the action of the tray 2 and the first connecting member 31. The two first clamping blocks 35 move away from the two sides of the surveying instrument. After both first clamping blocks 35 are disengaged from the surveying instrument, the surveying instrument can be removed from the tray 2. With this structure, the surveying instrument can be removed from the tray 2.

[0037] The two first springs 33 always provide a pulling force to the two first clamping blocks 35 in the direction of the surveying instrument, so that the two first clamping blocks 35 always keep in contact with the left and right sides of the surveying instrument during the UAV surveying process.

[0038] In this embodiment, the first vertical plate 37 is provided with a first through hole, and the first sliding rod 34 is slidably engaged in the first through hole. With this structure, the first sliding rod 34 can be slidably connected to the first vertical plate 37 from left to right.

[0039] In this embodiment, the upper side of the base frame 1 is recessed downwards at the positions corresponding to the two vertical plates to form a third sliding groove 13. The groove opening size of the third sliding groove 13 is smaller than the cavity size of the third sliding groove 13. Specifically, the cross-section of the third sliding groove 13 is dovetail-shaped. The third sliding groove 13 is arranged in the left-right direction. The lower ends of the two first vertical plates 37 are each fixed with a third slider 36. The two third sliders 36 are slidably engaged in the two third sliding grooves 13. With this structure, the lower ends of the first vertical plates 37 can be slidably connected to the base frame 1 in a left-right manner. Since the lower ends of the first vertical plates 37 can be slidably connected to the base frame 1 in a left-right manner, the first clamping part 3 can also be slidably connected to the base frame 1 in a left-right manner.

[0040] In this embodiment, it also includes a first abutment 5, a second abutment 6, a second connector 51, and a third connector 61. The first abutment 5 and the second abutment 6 can be slidably connected to the base frame 1. The first abutment 5 and the second abutment 6 are respectively located on the front and rear sides of the tray 2. The second connector 51 and the third connector 61 are respectively located on the front and rear sides of the tray 2. The front end of the second connector 51 is hinged to the first abutment 5, and the rear end is hinged to the tray 2. The rear end of the third connector 61 is hinged to the second abutment 6, and the front end is hinged to the tray 2.

[0041] When installing a surveying instrument on the UAV surveying instrument fixing device described in this utility model, after lifting the tray 2 to a certain distance from the base frame 1, the surveying instrument is placed on the tray 2. The first abutment part 5 is located on the front side of the tray 2. After the surveying instrument is placed on the tray 2, the tray 2 and the surveying instrument move downward under the action of gravity. The tray 2 drives one end of the second connecting member 51 to rotate downward. Since one end of the second connecting member 51 is hinged to the tray 2 and the other end is hinged to the first abutment part 5, during the downward rotation of one end of the second connecting member 51, the second connecting member 51 drives the first abutment part 5 to slide from the front side of the tray 2 toward the tray 2. Until the first abutment 5 abuts against the side of the surveying instrument, the first abutment 5 stops sliding, one end of the second connector 51 stops rotating downwards, and the tray 2 stops descending. With this structure, the second connector 51 can drive the first abutment 5 to slide from the front of the tray 2 toward the tray 2. The second abutment 6 is located at the rear of the tray 2. After the surveying instrument is placed in the tray 2, the tray 2 and the surveying instrument move downwards under gravity, and the tray 2 drives one end of the third connector 61 to rotate downwards. Since one end of the third connector 61 is hinged to the tray 2 and the other end is hinged to the second abutment 6, during the downward rotation of one end of the third connector 61, the third connector 61 drives the second abutment 6 to slide from the rear of the tray 2 toward the tray 2. Until the second abutment 6 abuts against the side of the surveying instrument, the second abutment 6 stops sliding, one end of the third connector 61 stops rotating downwards, and the tray 2 stops descending. With this structure, the third connector 61 can drive the second clamping part to slide from the front and rear sides of the tray 2 toward the tray 2. At this time, the surveying instrument can be clamped and fixed in the middle by the first abutment 5 and the second abutment 6. This structure further increases the stability of the surveying instrument during UAV surveying.

[0042] In this embodiment, the first supporting part 5 includes a second vertical plate 57, a second sliding rod 54, a second baffle 52, a second clamping block 55, and a second spring 53. The lower end of the second vertical plate 57 is slidably connected to the base frame 1. The second sliding rod 54 is slidably connected to the second vertical plate 57. The second baffle 52 is fixed to the end of the second sliding rod 54 away from the tray 2. The second clamping block 55 is fixed to the end of the second sliding rod 54 near the tray 2. The second spring 53 is sleeved on the second sliding rod 54. One end of the second spring 53 is connected to the second baffle 52, and the other end is connected to the second vertical plate 57.

[0043] The second supporting part 6 includes a third vertical plate 66, a third sliding rod 64, a third baffle 62, a third clamping block 65, and a third spring 63. The lower end of the third vertical plate 66 is slidably connected to the base frame 1. The third sliding rod 64 is slidably connected to the third vertical plate 66. The third baffle 62 is fixed to the end of the third sliding rod 64 away from the tray 2. The third clamping block 65 is fixed to the end of the third sliding rod 64 near the tray 2. The third spring 63 is sleeved on the third sliding rod 64. One end of the third spring 63 is connected to the third baffle 62, and the other end is connected to the third vertical plate 66.

[0044] When installing a surveying instrument on the UAV surveying instrument fixing device described in this utility model, after lifting the tray 2 to a certain distance from the base frame 1, the surveying instrument is placed on the tray 2. The second vertical plate 57 slides towards the tray 2 under the action of the tray 2 and the second connecting member 51. The third vertical plate 66 slides towards the tray 2 under the action of the tray 2 and the third connecting member 61. The second clamping block 55 abuts against the front side of the surveying instrument, and the third clamping block 65 abuts against the rear side of the surveying instrument. The second sliding rod 54 and the third sliding rod 64 both slide away from the tray 2. The second sliding rod 54 drives the second baffle 52 away from the tray 2 and stretches the second spring 53. The third sliding rod 64 drives the third baffle 62 away from the tray 2 and stretches the third spring 63. At this time, the second clamping block 55 and the third clamping block 65 clamp the front and rear sides of the surveying instrument. With this structure, the surveying instrument can be clamped and fixed in the middle by the first abutting part 5 and the second abutting part 6.

[0045] When disassembling the surveying instrument from the UAV surveying instrument fixing device described in this utility model, the tray 2 is lifted. The second vertical plate 57 slides away from the tray 2 under the influence of the tray 2 and the second connecting member 51. The third vertical plate 66 also slides away from the tray 2 under the influence of the tray 2 and the third connecting member 61. The second clamping block 55 moves away from the front side of the surveying instrument, and the third clamping block 65 moves away from the rear side of the surveying instrument. At this time, the second clamping block 55 and the third clamping block 65 are away from the front and rear sides of the surveying instrument. Because the tray 2 is lifted, the two first clamping blocks 35 also move away from the left and right sides of the surveying instrument. With this structure, the surveying instrument can be removed from the tray 2.

[0046] The second spring 53 always provides a pulling force to the second clamping block 55 in the direction of the surveying instrument, so that the second clamping block 55 always keeps in contact with the front side of the surveying instrument during the UAV surveying process; the third spring 63 always provides a pulling force to the third clamping block 65 in the direction of the surveying instrument, so that the third clamping block 65 always keeps in contact with the rear side of the surveying instrument during the UAV surveying process.

[0047] In this embodiment, the second vertical plate 57 is provided with a second through hole, and the second sliding rod 54 is slidably engaged in the second through hole. With this structure, the second sliding rod 54 can be slidably connected to the second vertical plate 57.

[0048] In this embodiment, the third vertical plate 66 is provided with a third through hole, and the third sliding rod 64 is slidably engaged in the third through hole. With this structure, the third sliding rod 64 can be slidably connected to the third vertical plate 66.

[0049] In this embodiment, the upper side of the base frame 1 is recessed downward to form a fourth sliding groove 14. The opening size of the fourth sliding groove 14 is smaller than the cavity size of the fourth sliding groove 14. Specifically, the cross-section of the fourth sliding groove 14 is dovetail-shaped. The third sliding groove 13 is arranged in the front-back direction. The lower ends of the second vertical plate 57 and the third vertical plate 66 protrude outward to form a fourth slider 56. The fourth slider 56 is slidably engaged in the fourth sliding groove 14. With this structure, the lower ends of the second vertical plate 57 and the third vertical plate 66 can be slidably connected to the base frame 1. Since the lower ends of the second vertical plate 57 and the third vertical plate 66 can be slidably connected to the base frame 1, the first abutment 5 and the second abutment 6 can also be slidably connected to the base frame 1.

[0050] In this embodiment, the connecting part 4 includes an electric push rod 42, a top plate 41, and a connecting rod 43. The upper end of the electric push rod 42 is fixed to the top plate 41, and the lower end is fixed to the base frame 1. The top plate 41 is located above the clamping part and directly opposite the tray 2. The bottom end of the connecting rod 43 is fixed to the top plate 41, and the top end is detachably connected to the bottom side of the UAV. The electric push rod can be a JC35L35 electric push rod.

[0051] When the UAV surveying instrument fixing device described in this utility model is in its initial state, the upper end of the electric push rod 42 is fixed to the top plate 41 and the lower end is fixed to the base frame 1, and the bottom end of the connecting rod 43 is fixed to the top plate 41. With this structure, the base frame 1 can be fixedly connected to the UAV through the connecting rod 43.

[0052] When installing the surveying instrument on the UAV surveying instrument fixing device described in this utility model, after lifting the tray 2 to a certain distance from the base frame 1, the surveying instrument is placed on the tray 2. The tray 2 and the surveying instrument move downward under the action of gravity, and the tray 2 drives one end of the first connecting member 31 to rotate downward. Since one end of the first connecting member 31 is hinged to the tray 2 and the other end is hinged to the first clamping part 3, during the downward rotation of one end of both first connecting members 31, the two first connecting members 31 drive the two first clamping parts 3 to slide simultaneously from the left and right sides of the tray 2 toward the tray 2. Until both first clamping parts 3 abut against the side of the surveying instrument, the first clamping parts 3 stop sliding, the one end of the first connecting member 31 stops rotating downward, and the tray 2 stops descending. At this time, the electric push rod 42 is retracted, driving the base frame 1, the tray 2, and the first clamping part 3 to move upward until the upper side of the surveying instrument abuts against the lower side of the top plate 41, and the retraction of the electric push rod 42 is stopped. This structure reduces the possibility that the surveying instrument may accidentally slip off the tray 2 during the drone's flight.

[0053] When removing the surveying instrument from the UAV surveying instrument fixing device described in this utility model, the electric push rod 42 is extended. The electric push rod 42 drives the base frame 1, tray 2, and first clamping part 3 to move downwards. After the base frame 1, tray 2, and first clamping part 3 have moved downwards a certain distance, the extension of the electric push rod 42 is stopped. At this time, the tray 2 is lifted, and the tray 2 drives one end of the first connecting member 31 to rotate upwards. Since one end of the first connecting member 31 is hinged to the tray 2 and the other end is hinged to the first clamping part 3, during the upward rotation of one end of both connecting members, the two first connecting members 31 drive the two first clamping parts 3 to slide simultaneously from the left and right sides of the tray 2 away from the tray 2. Until both first clamping parts 3 are disengaged from the side of the surveying instrument, the tray 2 is lifted, the first clamping parts 3 stop sliding, and one end of the first connecting member 31 stops rotating downwards. With this structure, the surveying instrument can be removed.

[0054] In this embodiment, the connecting part 4 further includes a mounting plate, multiple screws, and multiple nuts. The mounting plate is fixed to the upper side of the connecting rod 43. The mounting plate is provided with multiple fourth through holes, and the multiple fourth through holes and multiple nuts are all corresponding to the multiple screws. The multiple screws are all integrally formed on the lower side of the drone. After passing through the corresponding fourth through hole, the screws are screwed into the corresponding nuts. With this structure, the top end of the connecting rod 43 can be detachably connected to the bottom side of the drone.

[0055] In this embodiment, the tray 2 is provided with multiple support legs 21 on its lower side, and the lower ends of the support legs 21 are located below the base frame 1.

[0056] Before the drone takes off, the drone is supported on the ground, and multiple support legs 21 support the tray 2 on the ground. The base frame 1 is located at a certain distance below the tray 2.

[0057] When installing a surveying instrument on the UAV surveying instrument fixing device of this utility model, the surveying instrument is placed on the tray 2, and then the electric push rod 42 is retracted. The electric push rod 42 drives the base frame 1 to move upward, that is, the tray 2 can move downward relative to the base frame 1. After the base frame 1 moves upward a certain distance, the two first clamping parts 5 can clamp the surveying instrument, and the tray 2 stops descending. When installing a surveying instrument on the UAV surveying instrument fixing device of this utility model, the tray 2 does not need to be lifted specifically; the surveying instrument can be placed on the tray 2, making it more convenient to install the surveying instrument on the UAV surveying instrument fixing device of this utility model.

[0058] After the drone lands, the electric push rod 42 extends, causing the base frame 1, tray 2, support leg 21, and first clamping part 3 to move downwards. After the base frame 1, tray 2, support leg 21, and first clamping part 3 have moved downwards a certain distance, the lower end of the support leg 21 is located below the base frame 1, allowing it to abut against the ground, preventing further downward movement of the support leg 21 and the tray 2. As the electric push rod 42 continues to extend, the tray 2 moves upwards relative to the base frame 1, causing one end of the first connecting member 31 to rotate upwards. Since one end of the first connecting member 31 is hinged to the tray 2 and the other end is hinged to the first clamping part 3, as both ends of the connecting members rotate upwards, the two first connecting members 31 cause the two first clamping parts 3 to slide simultaneously from the left and right sides of the tray 2 away from the tray 2. This continues until both first clamping parts 3 are disengaged from the surveying instrument, at which point the surveying instrument can be removed from the tray 2. When removing the surveying instrument from the UAV surveying instrument fixing device of the present invention, the surveying instrument can be removed from the tray 2 without lifting the tray 2, making it more convenient to remove the surveying instrument from the UAV surveying instrument fixing device of the present invention.

[0059] In this embodiment, the base frame 1 includes a fixed frame 11 and a movable frame 12. The fixed frame 11 is located below the tray 2. The lower end of the electric push rod 42 is fixed to the fixed frame 11. The movable frame 12 is slidably connected to the front side of the fixed frame 11. The two first clamping parts 3 are slidably connected to the fixed frame 11. The first abutting part 5 is slidably disposed on the movable frame 12. The second abutting part 6 is slidably disposed on the fixed frame 11. The rear end of the second connecting member 51 is also slidably connected to the front side of the tray 2.

[0060] Before mounting the surveying instrument on the UAV surveying instrument fixing device of this utility model, the position of the surveying instrument lens can be referenced, and the movable frame 12 can be slid left and right on the fixing frame 11 to adjust the left and right positions of the movable frame 12 and the first abutment 5. When the surveying instrument is placed on the tray 2, the lens of the surveying instrument is facing forward. After the surveying instrument is placed on the tray 2, the first abutment 5 can avoid the lens of the surveying instrument, which can reduce the possibility that the first abutment 5 will block the lens of the surveying instrument.

[0061] In this embodiment, the front side of the fixed frame 11 extends inward to form a first sliding groove 15, and the rear side of the movable frame 12 extends outward to form a first slider 151, which slidably engages within the first sliding groove 15. The front side of the tray 2 extends inward to form a second sliding groove 22, and a second slider 221 slidably engages within the second sliding groove 22. The rear end of the second connecting member 51 is hinged to the second slider 221, and the second slider 221 is located within the second sliding groove 22, with the second sliding groove 22 and the second slider 221 engaging. The opening size of the first sliding groove 15 is smaller than the cavity size of the first sliding groove 15; specifically, the cross-section of the first sliding groove 15 is dovetail-shaped. The opening size of the second sliding groove 22 is smaller than the cavity size of the second sliding groove 22; specifically, the cross-section of the second sliding groove 22 is dovetail-shaped.

[0062] Since the front side of the fixed frame 11 is recessed inward to form a first sliding groove 15, and the rear side of the movable frame 12 is protruded outward to form a first slider 151, the first slider 151 is slidably engaged in the first sliding groove 15. With this structure, the movable frame 12 can be slidably connected to the front side of the fixed frame 11.

[0063] Because the front side of the tray 2 is recessed inward to form a second groove 22, and a second slider 221 is slidably fitted in the second groove 22, the rear end of the second connector 51 is hinged to the second slider 221. The second slider 221 is located in the second groove 22 and the second groove 22 and the second slider 221 are engaged. With this structure, the rear end of the second connector 51 can be hinged to the tray 2. The rear end of the second connector 51 can also be slidably connected to the rear end of the second connector 51 on the front side of the tray 2.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
