Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle technology, and more specifically to a shock-absorbing bracket for unmanned aerial vehicles and an unmanned aerial vehicle. Background Technology

[0002] In UAV systems, the IMU (Insulated Measurement Unit) is a core sensor, and its measurement accuracy is easily affected by the vibration of the aircraft. Therefore, a reliable vibration damping bracket is needed to reduce vibration interference. Current UAV vibration damping brackets have certain limitations in their structural design: the connection angle of their damping structure is fixed and cannot be adjusted according to the actual vibration direction, resulting in poor damping effect in non-perpendicular directions and difficulty in adapting to vibration requirements in different directions; at the same time, the distribution of damping components in existing brackets is not reasonable enough, usually failing to fully cover the outer perimeter of the bracket, resulting in limited isolation capability against multi-directional vibrations, especially with high-frequency disturbances, where the attenuation effect is unsatisfactory; furthermore, traditional bracket structures are relatively simple and fixed, lacking the ability to flexibly adjust the damping direction, making it difficult to adapt to the structural characteristics and vibration mode differences of different aircraft models, thus affecting the protection effect of the IMU and failing to effectively reduce the adverse effects of vibration. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a drone shock-absorbing bracket and drone, which aims to solve the technical problem that the traditional drone shock-absorbing bracket has limited vibration reduction capability in the non-vertical direction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A drone shock-absorbing bracket includes: an upper bracket, a lower bracket, a shock-absorbing module, and an adjustment module. The plane of the upper bracket is parallel to the plane of the lower bracket. The adjustment module is used to adjust the connection angle of the shock-absorbing module relative to the upper bracket and the lower bracket. The shock-absorbing module includes a plurality of shock-absorbing components spaced apart around the outer periphery of the upper bracket and the lower bracket. One end of each shock-absorbing component is rotatably connected to the upper bracket through the adjustment module, and the other end of each shock-absorbing component is rotatably connected to the lower bracket through the adjustment module.

[0006] In one embodiment, the shock-absorbing assembly includes an upper connecting seat, a lower connecting seat, and a shock-absorbing element. The adjustment module includes two sets of adjustment components respectively connected to the upper connecting seat and the lower connecting seat. The upper connecting seat is rotatably connected to the upper support through the adjustment components, and the lower connecting seat is rotatably connected to the lower support through the adjustment components. The shock-absorbing element is disposed between the upper connecting seat and the lower connecting seat.

[0007] In one embodiment, the adjusting assembly includes a rotating rod and a return spring, the return spring being sleeved on the rotating rod.

[0008] In one embodiment, the upper support is provided with a plurality of upper connecting arms that cooperate with the upper connecting seat. The upper connecting arm includes a first connecting portion and a second connecting portion that are parallel to each other on a horizontal plane. One end of the rotating rod is rotatably connected to the first connecting portion, and the other end of the rotating rod is rotatably connected to the second connecting portion.

[0009] In one embodiment, the upper connecting seat has a connecting spline at one end near the second connecting portion, and the second connecting portion has ratchet teeth that engage with the connecting spline at one end near the upper connecting seat.

[0010] In one embodiment, the lower support is provided with a plurality of lower connecting arms that cooperate with the lower connecting seat.

The lower connecting seat is snapped into the fourth connecting portion.

[0011] In one embodiment, the lower connecting seat has a connecting spline at one end near the fourth connecting portion, and the fourth connecting portion has ratchet teeth that engage with the connecting spline at one end near the upper connecting seat.

[0012] In one embodiment, the shock absorber includes a connecting rod and at least one shock absorber ball. One end of the connecting rod is connected to the upper connecting seat, and the other end is connected to the lower connecting seat. The shock absorber ball is disposed between the upper connecting seat and the lower connecting seat.

[0030] See Figures 1 to 6As shown in the figure, this utility model embodiment discloses a drone shock-absorbing bracket, including: an upper bracket 1, a lower bracket 2, a shock-absorbing module 3, and an adjustment module 4. The plane where the upper bracket 1 is located is parallel to the plane where the lower bracket 2 is located. The adjustment module 4 is used to adjust the connection angle of the shock-absorbing module 3 relative to the upper bracket 1 and the lower bracket 2. The shock-absorbing module 3 includes a plurality of shock-absorbing components 31 distributed at intervals around the outer periphery of the upper bracket 1 and the lower bracket 2. One end of the shock-absorbing component 31 is rotatably connected to the upper bracket 1 through the adjustment module 4, and the other end of the shock-absorbing component 31 is rotatably connected to the lower bracket 2 through the adjustment module 4.

[0031] Specifically, in this embodiment, the UAV vibration damping bracket includes an upper bracket 1, a lower bracket 2, a vibration damping module 3, and an adjustment module 4. The plane of the upper bracket 1 is parallel to the plane of the lower bracket 2. The adjustment module 4 is used to adjust the connection angle of the vibration damping module 3 relative to the upper bracket 1 and the lower bracket 2. The vibration damping module 3 includes several vibration damping components 31 spaced around the outer periphery of the upper bracket 1 and the lower bracket 2, and the two ends of the vibration damping components 31 are rotatably connected to the upper bracket 1 and the lower bracket 2 respectively through the adjustment module 4. By adjusting the connection angle of the vibration damping components 31 through the adjustment module 4, and combining the multiple vibration damping components 31 spaced around the periphery, vibration can be addressed in multiple directions, thereby improving the adaptability to different vibration directions, the vibration damping capability in non-perpendicular directions, and the high-frequency disturbance attenuation effect, and better reducing the interference of vibration on the IMU. When the UAV vibrates, the adjustment module 4 can adjust the connection angle of the vibration damping components 31 according to the actual vibration direction, so that each vibration damping component 31 works together to absorb and attenuate vibrations in different directions using its own structural characteristics, reducing the vibration transmitted to the IMU. It is understood that, in this embodiment, four sets of shock-absorbing components 31 are preferably evenly distributed around the outer periphery of the upper support 1 and the lower support 2, respectively. In other embodiments, the number of shock-absorbing components 31 can be adjusted according to actual needs, as long as they are distributed at intervals around the outer periphery to prevent the center of gravity from shifting.

[0032] In one embodiment, the shock-absorbing component 31 includes an upper connecting seat 311, a lower connecting seat 312, and a shock-absorbing element 313. The adjustment module 4 includes two sets of adjustment components 41 respectively connected to the upper connecting seat 311 and the lower connecting seat 312. The upper connecting seat 311 is rotatably connected to the upper support 1 through the adjustment components 41, and the lower connecting seat 312 is rotatably connected to the lower support 2 through the adjustment components 41. The shock-absorbing element 313 is disposed between the upper connecting seat 311 and the lower connecting seat 312.

[0033] Specifically, the damping component 31 consists of an upper connecting seat 311, a lower connecting seat 312, and a damping element 313. The adjustment module 4 includes two sets of adjustment components 41 respectively connected to the upper connecting seat 311 and the lower connecting seat 312. The upper connecting seat 311 is rotatably connected to the upper support 1 through the adjustment components 41, and the lower connecting seat 312 is rotatably connected to the lower support 2 through the adjustment components 41. The damping element 313 is disposed between the upper connecting seat 311 and the lower connecting seat 312. By cooperating with the adjustment components 41, the upper connecting seat 311 and the lower connecting seat 312 respectively, the damping component 31 is rotatably connected to the upper support 1 and the lower support 2. At the same time, the damping element 313 directly plays a damping role between the upper and lower connecting seats 312, further improving the damping effect and the stability of the angle adjustment. When the adjustment component 41 is activated, it drives the upper connecting seat 311 and the lower connecting seat 312 to rotate relative to the upper bracket 1 and the lower bracket 2, thereby adjusting the angle of the damping component 31. The damping component 313 absorbs energy during the vibration transmission process and reduces the impact of vibration.

[0034] In one embodiment, the adjusting assembly 41 includes a rotating rod 411 and a return spring 412, the return spring 412 being sleeved on the rotating rod 411.

[0035] Specifically, the adjustment assembly 41 includes a rotating rod 411 and a return spring 412, with the return spring 412 sleeved on the rotating rod 411. The rotating rod 411 provides support and a rotation axis for the rotation of the upper connecting seat 311 and the lower connecting seat 312. The return spring 412, after rotational adjustment, allows the upper connecting seat 311 and the lower connecting seat 312 to return to their initial position or remain in a stable state after adjustment, ensuring angular stability and structural reliability after adjustment. When the angle of the damping assembly 31 needs to be adjusted, an external force is applied to rotate the upper connecting seat 311 or the lower connecting seat 312 around the rotating rod 411, at which point the return spring 412 is compressed. When the external force is removed, the elastic force of the return spring 412 drives the upper connecting seat 311 or the lower connecting seat 312 back to its initial position, achieving stable angle adjustment.

[0036] In one embodiment, the upper bracket 1 is provided with a plurality of upper connecting arms 11 that cooperate with the upper connecting seat 311. The upper connecting arm 11 includes a first connecting portion 111 and a second connecting portion 112 parallel to each other on a horizontal plane. One end of the rotating rod 411 is rotatably connected to the first connecting portion 111, and the other end of the rotating rod 411 is rotatably connected to the second connecting portion 112. The upper connecting seat 311 is movably connected to the rotating rod 411 and is disposed between the return spring 412 and the second connecting portion 112. The upper connecting seat 311 is snapped into the second connecting portion 112.

[0037] Specifically, the upper support 1 is provided with several upper connecting arms 11 that cooperate with the upper connecting seat 311. Each upper connecting arm 11 includes a first connecting portion 111 and a second connecting portion 112 parallel to each other on a horizontal plane. One end of the rotating rod 411 is rotatably connected to the first connecting portion 111, and the other end is rotatably connected to the second connecting portion 112. The upper connecting seat 311 is movably connected to the rotating rod 411 and is located between the return spring 412 and the second connecting portion 112. The upper connecting seat 311 is engaged with the second connecting portion 112. The first connecting portion 111 and the second connecting portion 112 of the upper connecting arm 11 provide stable support for the rotating rod 411, ensuring that the rotating rod 411 can rotate smoothly. The upper connecting seat 311 can move and rotate on the rotating rod 411 and then be engaged with the second connecting portion 112. Combined with the function of the return spring 412, the upper connecting seat 311 can be stably held in the set position after rotational adjustment, improving the overall stability of the structure.

[0038] When it is necessary to adjust the angle of the upper connecting seat 311, an external force is applied to move the upper connecting seat 311 along the length direction relative to the rotation axis, so that the upper connecting seat 311 is separated from the second connecting part 112. Then, the upper connecting seat 311 is rotated so that it rotates around the rotating rod 411 between the first connecting part 111 and the second connecting part 112 until the appropriate angle is adjusted. At this time, the return spring 412 is compressed. When the angle is determined, the external force is removed, and the elastic restoring force of the return spring 412 drives the upper connecting seat 311 to return to its original position and lock into the corresponding position of the second connecting part 112, thereby fixing the angle.

[0039] In one embodiment, the upper connecting seat 311 is provided with a connecting spline 3111 at one end near the second connecting part 112, and the second connecting part 112 is provided with a ratchet tooth 1121 that engages with the connecting spline 3111 at one end near the upper connecting seat 311.

[0040] Specifically, the upper connecting seat 311 has a connecting spline 3111 at one end near the second connecting part 112, and the second connecting part 112 has a ratchet tooth 1121 that engages with the connecting spline 3111 at one end near the upper connecting seat 311. The engagement of the connecting spline 3111 and the ratchet tooth 1121 enables a reliable engagement between the upper connecting seat 311 and the second connecting part 112. The rotation angle of the upper connecting seat 311 can be precisely adjusted by meshing different tooth positions, and a stable positioning can be provided after adjustment to prevent the angle from shifting during vibration. When the upper connecting seat 311 rotates to the required angle, it is reset by the assistance of the return spring 412. The connecting spline 3111 engages and locks with the corresponding ratchet tooth 1121, and the two fit tightly together, so that the upper connecting seat 311 is stably maintained at that angle position. It is understood that in this embodiment, the accuracy of angle adjustment depends on the adaptive adjustment of the number of teeth of the ratchet 1121. The more teeth the ratchet 1121 has, the higher the adjustable angle accuracy. In actual production, adaptive design can be carried out according to the needs. No specific limitation is made in this embodiment.

[0041] In one embodiment, the lower support 2 is provided with a plurality of lower connecting arms 21 that cooperate with the lower connecting seat 312. The lower connecting arm 21 includes a third connecting portion 211 and a fourth connecting portion 212 that are parallel to each other on a horizontal plane. One end of the rotating rod 411 is rotatably connected to the third connecting portion 211, and the other end of the rotating rod 411 is rotatably connected to the fourth connecting portion 212. The lower connecting seat 312 is movably connected to the rotating rod 411 and is disposed between the return spring 412 and the fourth connecting portion 212. The lower connecting seat 312 is engaged with the fourth connecting portion 212.

[0042] Specifically, the lower support 2 is provided with several lower connecting arms 21 that mate with the lower connecting seat 312. Each lower connecting arm 21 includes a third connecting portion 211 and a fourth connecting portion 212 parallel to each other on a horizontal plane. One end of the rotating rod 411 is rotatably connected to the third connecting portion 211, and the other end is rotatably connected to the fourth connecting portion 212. The lower connecting seat 312 is movably connected to the rotating rod 411 and is positioned between the return spring 412 and the fourth connecting portion 212. The lower connecting seat 312 is engaged with the fourth connecting portion 212. The third connecting portion 211 and the fourth connecting portion 212 of the lower connecting arm 21 provide stable support for the rotating rod 411. After the rotating rod 411 rotates and moves, the lower connecting seat 312 engages with the fourth connecting portion 212. In conjunction with the return spring 412, this ensures that the lower connecting seat 312 can be stably maintained in its initial engaged position after rotational adjustment, thus guaranteeing the stability of the overall structure.

[0043] When it is necessary to adjust the angle of the lower connecting seat 312, an external force is applied to move the lower connecting seat 312 along the length direction relative to the rotation axis, so that the lower connecting seat 312 is separated from the fourth connecting part 212. Then, the lower connecting seat 312 is rotated so that it rotates around the rotating rod 411 between the third connecting part 211 and the fourth connecting part 212 until the appropriate angle is adjusted. At this time, the return spring 412 is compressed. When the angle is determined, the external force is removed, and the elastic restoring force of the return spring 412 drives the lower connecting seat 312 to return to its original position and lock into the corresponding position of the fourth connecting part 212, thereby fixing the angle.

[0044] In one embodiment, the lower connecting seat 312 is provided with a connecting spline 3111 at one end near the fourth connecting part 212, and the fourth connecting part 212 is provided with a ratchet tooth 1121 that engages with the connecting spline 3111 at one end near the upper connecting seat 311.

[0045] Specifically, the lower connecting seat 312 has a connecting spline 3111 at one end near the fourth connecting part 212, and the fourth connecting part 212 has a ratchet tooth 1121 that engages with the connecting spline 3111 at one end near the upper connecting seat 311. The engagement of the connecting spline 3111 and the ratchet tooth 1121 ensures reliable engagement between the lower connecting seat 312 and the fourth connecting part 212. The rotation angle of the lower connecting seat 312 can be precisely adjusted by different tooth positions, and it is stably positioned after adjustment to prevent vibration from causing angle deviation. After the lower connecting seat 312 rotates to the required angle, it is reset with the assistance of the return spring 412. The connecting spline 3111 engages and locks with the corresponding ratchet tooth 1121, and the two work closely together to keep the lower connecting seat 312 stably maintained at that angle position. It is understood that in this embodiment, the accuracy of angle adjustment depends on the adaptive adjustment of the number of teeth of the ratchet 1121. The more teeth the ratchet 1121 has, the higher the adjustable angle accuracy. In actual production, adaptive design can be carried out according to the needs. No specific limitation is made in this embodiment.

[0046] In one embodiment, the shock absorber 313 includes a connecting rod 3131 and at least one shock absorber ball 3132. One end of the connecting rod 3131 is connected to the upper connecting seat 311, and the other end is connected to the lower connecting seat 312. The shock absorber ball 3132 is disposed between the upper connecting seat 311 and the lower connecting seat 312.

[0047] Specifically, the damping component 313 includes a connecting rod 3131 and at least one damping ball 3132. One end of the connecting rod 3131 is connected to the upper connecting seat 311, and the other end is connected to the lower connecting seat 312. The damping ball 3132 is disposed between the upper connecting seat 311 and the lower connecting seat 312. The connecting rod 3131 connects the upper connecting seat 311 and the lower connecting seat 312 into a whole, ensuring the transmission of force. The damping ball 3132 absorbs and attenuates vibration energy through its own elastic deformation. Multiple damping balls 3132 can enhance the damping effect and adapt to vibrations of different intensities. When vibration occurs, the vibration is transmitted to the connecting rod 3131 through the upper connecting seat 311 or the lower connecting seat 312, and then to the damping ball 3132. The damping ball 3132 undergoes elastic deformation, converting the vibration energy into internal energy and dissipating it, thereby reducing the vibration transmitted to the other end. It is understandable that multiple shock-absorbing balls 3132 can enhance the shock absorption effect. In this embodiment, two shock-absorbing balls 3132 are preferably symmetrically distributed at both ends of the connecting rod 3131. In practical applications, the number of shock-absorbing balls 3132 can be adjusted according to the needs.

[0048] In one embodiment, the adjustment angle range of the shock absorption module 3 is 0°-60°.

[0049] Specifically, the adjustment angle range of the shock absorption module 3 is 0°-60°. This range satisfies the vibration direction adjustment needs of most drones under different operating conditions while preventing excessive angles from reducing structural stability, thus ensuring both adaptability and structural strength of the support. The adjustment component 41 allows the rotation angle of the shock absorption component 31 to vary between 0° and 60° to adapt to vibrations of different directions and intensities. When the angle reaches 60°, the adjustment component 41 restricts further rotation, ensuring adjustment within a safe range. It is understood that in this embodiment, the shock absorption module 3 limits the adjustment angle range through a limiting engagement structure corresponding to the spline 3111 and the ratchet teeth 1121. The number of teeth on the ratchet teeth 1121 determines the angle adjustment accuracy.

[0050] A drone includes a drone body and the aforementioned drone shock-absorbing bracket, wherein the drone shock-absorbing bracket is disposed below the drone body; an external load 5 is installed on the upper bracket 1 of the drone shock-absorbing bracket.

[0051] Specifically, the drone vibration damping bracket is located below the drone body, and an external load 5 is mounted on the upper bracket 1 of the drone vibration damping bracket. Applying the drone vibration damping bracket to the drone utilizes its vibration damping and angle adjustment functions to reduce the impact of vibrations generated during drone flight on the external load 5, especially protecting the external load 5 (such as an IMU) mounted on the upper bracket 1, thereby improving the drone's operational stability and load measurement accuracy. When the drone is in flight, vibrations generated by the engine or propeller are transmitted to the drone body and then to the vibration damping bracket below. The vibration damping bracket adjusts the angle of the vibration damping component 31 through the adjustment module 4, using the vibration damping module 3 to absorb and attenuate vibrations, significantly reducing the vibration interference experienced by the external load 5 on the upper bracket 1, ensuring its normal operation. It is understood that in this embodiment, the external load 5 is an IMU, and the drone vibration damping bracket is fixed to the lower part of the drone body by bolts.

[0052] In summary, the UAV vibration damping bracket and UAV of this embodiment, by setting the adjustment module 4, can flexibly adjust the connection angle of the vibration damping module 3 relative to the upper bracket 1 and the lower bracket 2. With the cooperation of multiple vibration damping components 31 distributed around the outer periphery, the vibration damping capability in the non-vertical direction is effectively improved, and the adaptation to different vibration directions is achieved. The two ends of the vibration damping component 31 are rotatably connected by the adjustment module 4. Combined with the elastic deformation of the vibration damping component 313, the isolation effect of multi-directional vibration is enhanced, and the attenuation capability of high-frequency disturbances is improved. The cooperation structure of the upper connecting seat 311, the lower connecting seat 312 and the connecting arm, as well as the snap-fit ​​design of the connecting spline 3111 and the ratchet tooth 1121, ensure the stability after the angle adjustment. This makes the bracket no longer limited to a fixed single structure, and can better adapt to the structure and vibration mode of different models, thereby significantly reducing the interference of vibration on external loads 5 such as IMU, and improving the stability of UAV flight control and sensor measurement accuracy.

[0053] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
