Description

Technical Field

[0001] This utility model relates to the field of drone auxiliary device technology, and in particular to a drone mapping process stabilization device and a drone. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly widely used in surveying and mapping. Drone surveying, with its high efficiency, flexibility, and accuracy, plays a vital role in various fields such as geographic information collection, urban planning, environmental monitoring, and agricultural management. However, during drone surveying, due to environmental factors (such as wind and airflow changes) or improper operation, drones are prone to slight tilting. Although this tilt may seem minor, it can accumulate over time or, under certain conditions, seriously affect the accuracy of surveying data and the safety of the drone.

[0003] In traditional UAV mapping, monitoring the flight attitude of the UAV mainly relies on built-in inertial navigation systems such as gyroscopes and accelerometers. Although these systems can sense and correct the flight attitude to a certain extent, they are often not sensitive or accurate enough in sensing and responding to slight tilts. In addition, during the landing process, the UAV is prone to structural damage due to its own kinetic energy and the impact force when it contacts the ground, which affects its subsequent use. Therefore, in order to address the above technical problems, a UAV mapping process stabilization device and a UAV are proposed here. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where the monitoring of UAV flight attitude mainly relies on built-in inertial navigation systems such as gyroscopes and accelerometers. These systems are often not sensitive and accurate enough in sensing and responding to slight tilts. This invention provides a stabilization device for UAV mapping process and a UAV.

[0005] In a first aspect, this utility model provides a stabilization device for UAV mapping processes, comprising:

[0006] The mounting sleeve is capable of forming a fixed connection with the main body of the drone, and the mounting sleeve has a first internal space;

[0007] A column is fixedly connected to the first inner space. A circular groove is provided on the top of the column. A ball bearing is rotatably connected inside the circular groove. A connecting rod is fixedly connected to the ball bearing and extends out of the circular groove.

[0008] A tension sensing mechanism is fixedly connected to the first inner space. A pull rope is fixedly connected to the part of the tension sensing mechanism and the part of the connecting rod that extends out of the circular groove. The pull rope is in a taut state.

[0009] The stabilization device for UAV mapping described in this utility model provides a space for the first inner space of the mounting sleeve to house the column and the tension sensing mechanism. The column provides a space for the circular groove, so that after the mounting sleeve is fixedly connected to the UAV, when the UAV tilts during flight, it causes the mounting sleeve to tilt, which in turn causes the circular groove to tilt. This causes the ball bearings to rotate in the tilt direction within the circular groove, which in turn causes the connecting rod to tilt. The connecting rod pulls the pull rope, which is in a taut state. Therefore, the tension sensing mechanism can instantly sense the force generated by the UAV tilt and issue a warning, reminding the user to adjust the balance in time to ensure that the UAV is in a relatively balanced state. In this way, it is possible to monitor the slight tilt of the UAV and accurately calculate the tilt direction and accuracy, thus providing a good auxiliary effect on the stability of the UAV mapping process.

[0010] Preferably, a mounting plate is fixedly connected to the top of the connecting rod, and a first connecting member is fixedly connected to the mounting plate;

[0011] The number of the first connector and the tension sensing mechanism are corresponding and at least two are provided. The first connector and the tension sensing mechanism are arranged in a ring. The first connector and the corresponding tension sensing mechanism are fixedly connected by the corresponding pull rope.

[0012] By setting up the mounting plate, it is easy to install at least two first connectors in the circumferential direction, and then at least two sets of first connectors, pull ropes and tension sensing mechanisms can be installed in the circumferential direction, enabling monitoring in at least two directions and improving fault tolerance.

[0013] Preferably, the tension sensing mechanism includes:

[0014] Mounting base, which is fixedly connected to the mounting sleeve.

[0015] A tension sensor, which is fixedly connected to a mounting base.

[0016] The second connector is fixedly connected to the tension sensor, and the pull rope is fixedly connected between the first connector and the second connector.

[0017] It facilitates the connection of the tension sensor to the ball bearing, which helps the tension sensor detect changes in tension caused by the tilt of the drone.

[0018] Preferably, the column is fixedly connected to the center of the mounting sleeve.

[0019] This makes the arrangement of the first connector, pull rope, and tension sensing mechanism more balanced, which helps to ensure tension sensing in all directions.

[0020] Preferably, it also includes a base, the base having a second inner space, the base being fixedly connected to the bottom of the drone body, the mounting sleeve being fixedly connected to the first inner space, and a buffer device being provided on the outer side of the base.

[0021] By setting a base for fixed connection to the bottom of the drone, the mounting sleeve can form a fixed connection with the drone body to facilitate the tilting of the drone; at the same time, a buffer device is provided on the outside of the base to buffer the impact force when the drone lands after flight, which greatly protects the stability of the overall structure and avoids damage.

[0022] Preferably, the buffer device includes:

[0023] A rotating component is fixedly connected to the bottom of the base. A buffer rod is rotatably connected to the rotating component. A sleeve rod is slidably connected to the end of the buffer rod. The buffer rod can abut against the ground.

[0024] A slide rail is fixedly connected to the opposite side of the base, and a buffer mechanism is slidably connected to the slide rail. The buffer mechanism is fixedly connected to the sleeve rod.

[0025] When the drone lands after flight, the bottom of the buffer rod touches the ground, causing it to rotate around the rotating component. At this time, under the action of force, the sleeve rod can drive the buffer mechanism to slide on the slide rail to dissipate energy.

[0026] Preferably, the buffer rod has a multi-segmented curved structure, and the bottom of the buffer rod can abut against the ground.

[0027] Preferably, the buffer mechanism includes:

[0028] A slider, which is slidably connected to the slide rail, and a sleeve rod, which is fixedly connected to the slider;

[0029] A spring is fixedly connected between the slider and the slide rail.

[0030] When the drone lands after flight, the bottom of the buffer rod touches the ground and rotates around the rotating component. At this time, under the action of force, the sleeve rod can drive the slider to compress the spring, which can buffer the impact force and transform the impact force on the drone into the contraction force on the spring, which greatly protects the stability of the overall structure and avoids damage.

[0031] In a second aspect, this utility model provides a drone, including the drone mapping process stabilization device and the drone body as described above;

[0032] A mounting frame is fixedly connected to the upper side of the main body of the drone, and a spiral blade is connected to the upper side of the mounting frame.

[0033] The stabilization device for the UAV mapping process is fixedly connected to the main body of the UAV.

[0034] The UAV described in this utility model, through the stabilization device in the UAV mapping process, can monitor the slight tilt of the UAV and accurately calculate the tilt direction and accuracy, which provides a good auxiliary effect on the stability of the UAV mapping process, ensures the relative balance of the UAV, and improves the safety of use.

[0035] Preferably, the stabilization device for the UAV mapping process is fixedly connected to the lower side of the UAV body;

[0036] And / or, the helical blades are detachably connected to the mounting bracket;

[0037] And / or, a surveying device is fixedly connected to the outside of the main body of the UAV.

[0038] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0039] 1. This utility model provides a stabilization device for the UAV mapping process. The first inner space of the mounting sleeve provides space for the column and the tension sensing mechanism. The column provides the setting conditions for the circular groove. After the mounting sleeve is fixedly connected to the UAV, when the UAV tilts during flight, it causes the mounting sleeve to tilt, which in turn causes the circular groove to tilt. This causes the ball bearing to rotate in the tilt direction within the circular groove, which in turn causes the connecting rod to tilt. The connecting rod pulls the pull rope, which is in a taut state. Therefore, the tension sensing mechanism can instantly sense the force generated by the UAV tilt and issue a warning, reminding the user to adjust the balance in time to ensure that the UAV is in a relatively balanced state. In this way, the small tilt of the UAV can be monitored and the tilt direction and accuracy can be accurately calculated, which provides a good auxiliary effect on the stability of the UAV mapping process.

[0040] 2. The UAV provided by this utility model can monitor the slight tilt of the UAV during the UAV surveying process through the UAV surveying process stabilization device, and accurately calculate the tilt direction and accuracy, which provides a good auxiliary effect on the stability of the UAV surveying process, ensures the relative balance of the UAV, and improves the safety of use.

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0050] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

Therefore, they should not be construed as limitations on this utility model.

[0051] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation.

As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0052] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0053] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0055] Example 1

[0056] like Figures 1-7 As shown, a stabilization device for UAV mapping includes a mounting sleeve 2, a column 3, and a tension sensing mechanism.

[0057] like Figure 7 As shown, the mounting sleeve 2 can form a fixed connection with the drone body 19. The connection between the mounting sleeve 2 and the drone body 19 can be a direct connection or an indirect connection; for example... Figure 1 and Figure 2 As shown, the mounting sleeve 2 has a first inner space;

[0058] like Figure 2 As shown, the column 3 is fixedly connected to the first inner space. A circular groove 4 is provided on the top of the column 3. A ball bearing 5 is rotatably connected inside the circular groove 4. A connecting rod 6 is fixedly connected to the ball bearing 5. The connecting rod 6 extends out from the circular groove 4.

[0059] like Figure 2 As shown, the tension sensing mechanism is fixedly connected to the first inner space, and the tension sensing mechanism and the part of the connecting rod 6 extending out of the circular groove 4 are fixedly connected to a pull rope 12, which is in a taut state.

[0060] The stabilization device for UAV mapping described in this utility model provides a space for the first inner space of the mounting sleeve 2 to house the column 3 and the tension sensing mechanism. The column 3 provides a space for the circular groove 4. After the mounting sleeve 2 is fixedly connected to the UAV, when the UAV tilts during flight, it causes the mounting sleeve 2 to tilt, which in turn causes the circular groove 4 to tilt. This causes the ball bearing 5 to rotate in the tilt direction within the circular groove 4, which in turn causes the connecting rod 6 to tilt. The connecting rod 6 pulls the pull rope 12, which is in a taut state. Therefore, the tension sensing mechanism can instantly sense the force generated by the tilt of the UAV and issue a warning to remind the user to adjust the balance in time to ensure that the UAV is in a relatively balanced state. In this way, the device can monitor the slight tilt of the UAV and accurately calculate the tilt direction and accuracy, thus providing a good auxiliary effect on the stability of the UAV mapping process.

[0061] Example 2

[0062] A stabilization device for UAV mapping process, based on Embodiment 1, such as... Figures 1-7 As shown, the stabilization device for UAV mapping also includes a base 1, which has a second inner space. The base 1 is fixedly connected to the bottom of the UAV body 19, and the mounting sleeve 2 is fixedly connected to the first inner space. A buffer device is provided on the outer side of the base 1. By setting the base 1 to be fixedly connected to the bottom of the UAV, the mounting sleeve 2 can form an indirect fixed connection with the UAV body 19 to transfer the tilt of the UAV. At the same time, the buffer device on the outer side of the base 1 can buffer the impact force when the UAV lands after flight, greatly protecting the stability of the overall structure and avoiding damage.

[0063] Example 3

[0064] A stabilization device for UAV mapping processes has been further optimized based on Embodiments 1 and 2. Please refer to... Figures 1-7 A stabilization device for UAV mapping process includes: a base 1, a mounting sleeve 2, a rotating component 13, and a slide rail 16.

[0065] like Figure 7As shown, the base 1 is fixedly connected to the bottom of the drone body 19.

[0066] like Figure 1 and Figure 2 As shown, the mounting sleeve 2 is fixedly connected to the inside of the base 1. A column 3 is fixedly connected to the center of the mounting sleeve 2. A circular groove 4 is opened on the top of the column 3. A ball bearing 5 is rotatably connected inside the circular groove 4. A connecting rod 6 is fixedly connected to the outside of the ball bearing 5. A mounting plate 7 is fixedly connected to the top of the connecting rod 6. A first connecting piece 8 is fixedly connected to the outside of the mounting plate 7. A tension sensing mechanism is installed on the inside of the mounting sleeve 2. A pull rope 12 is fixedly connected between the tension sensing mechanism and the first connecting piece 8.

[0067] like Figure 1 and Figure 2 As shown, the number of the first connector 8 and the tension sensing mechanism are several groups arranged in a ring, and the first connector 8 corresponds to each group of tension sensing mechanism. By setting multiple groups of tension sensors 10, it is convenient to monitor in all directions and improve fault tolerance.

[0068] like Figure 4 As shown, the tension sensing mechanism includes a mounting base 9, a tension sensor 10, and a second connecting member 11. The mounting base 9 and the mounting sleeve 2 are fixedly connected, the tension sensor 10 and the mounting base 9 are fixedly connected, the second connecting member 11 and the tension sensor 10 are fixedly connected, and the pull rope 12 is fixedly connected between the first connecting member 8 and the second connecting member 11.

[0069] Each set of pull ropes 12 is taut and has a certain degree of elasticity, which facilitates the transmission of tension from the pull ropes 12 to the tension sensor 10 for monitoring, thereby improving the sensitivity of the detection.

[0070] The working principle of the stabilization device for UAV mapping in this embodiment is as follows: when the UAV equipped with this stabilization device is mapping, if it tilts slightly, the ball bearings 5 ​​inside the circular groove 4 will cause the mounting plate 7 to tilt to one side under the action of gravity. This will pull the rope 12 on the opposite side through the first connector 8, which will be detected by the corresponding tension sensor 10. The tension can be sensed, and the unbalanced state can be determined. The tilt degree is accurately calculated by the installation position of the tension sensors 10 at each part, and a warning is issued to remind the user to adjust the balance in time to ensure that the UAV is in a relatively balanced state. In this way, the slight tilt of the UAV can be monitored and the tilt direction and accuracy can be accurately calculated, which provides a good auxiliary role in the stability of the UAV mapping process.

[0071] Example 4

[0072] Please see Figures 1-7Based on embodiments 2 and 3, the rotating component 13 is fixedly connected to the bottom of the base 1, the external part of the rotating component 13 is rotatably connected to the buffer rod 14, the end of the buffer rod 14 is slidably connected to the sleeve rod 15, the slide rail 16 is fixedly connected to both sides of the base 1, the slide rail 16 is internally installed with a buffer mechanism, and the buffer mechanism is fixedly connected to the sleeve rod 15.

[0073] The buffer rod 14 has a multi-segment curved structure, and the bottom of the buffer rod 14 can abut against the ground, thus avoiding the bottom surface of the base 1 from being damaged by impact when it comes into contact with the ground.

[0074] The buffer mechanism includes a slider 17 and a spring 18. The slider 17 is slidably connected to the inner side of the slide rail 16, the spring 18 is fixedly connected between the slider 17 and the slide rail 16, and the sleeve 15 is fixedly connected to the outside of the slider 17.

[0075] In this embodiment, when the drone lands after flight, it has a certain kinetic energy and thus a certain impact force when it contacts the ground. At this time, the bottom of the buffer rod 14 can be driven to rotate around the rotating part 13 by contacting the ground. Under the action of force, the sleeve rod 15 can be driven to push the slider 17 to slide upward in the slide rail 16, which can drive the spring 18 to be compressed, thereby buffering the impact force and converting the impact force on the base 1 into the contraction force on the spring 18, which greatly protects the stability of the overall structure and avoids damage.

[0076] Example 5

[0077] like Figure 7 As shown, a drone includes a drone mapping process stabilization device and a drone body 19 as described in Embodiments 1, 2, 3 or 4 above;

[0078] A mounting frame 20 is fixedly connected to the upper side of the drone body 19, and a spiral blade 21 is connected to the upper side of the mounting frame 20.

[0079] The stabilization device for the UAV mapping process is fixedly connected to the main body 19 of the UAV.

[0080] In an optional implementation, the stabilization device for the UAV mapping process is fixedly connected to the lower side of the UAV body 19, which facilitates the installation of the stabilization device for the UAV mapping process and can lower the center of gravity of the UAV, which is beneficial to the stability of the UAV flight.

[0081] In an optional embodiment, the helical blade 21 is detachably connected to the mounting bracket 20 to facilitate replacement of the helical blade 21;

[0082] In an optional implementation, a surveying device 22 is fixedly connected to the outside of the UAV body 19 to facilitate surveying.

[0083] The UAV described in this embodiment, through the UAV mapping process stabilization device, can monitor the slight tilt of the UAV and accurately calculate the tilt direction and accuracy, providing good assistance for the stability of the UAV mapping process, ensuring the relative balance of the UAV, and improving the safety of use. Furthermore, after setting the base 1 and the buffer device on the outside of the base 1, the impact force can be buffered when the UAV lands after flight, greatly protecting the stability of the overall structure and preventing damage.

[0084] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
