[0002] With the continuous advancement and development of science and technology, the technology of using drones has been vigorously developed and promoted. Drones are small in size, low in energy consumption and easy to operate. Drones have been fully utilized in disaster assessment, emergency rescue, on-site reconnaissance, tourism photography and other fields.

[0003] Motors, commonly known as "motors," are the power source of drones. Drones adjust their flight state by varying the motor's speed. By varying the speed of each motor, the drone can hover, ascend, descend, or move in various directions. Motors are categorized as either "brushless" or "brushed." Most drones on the market today use brushless motors. Brushless motors utilize semiconductor switching devices for electronic commutation, offering advantages such as high reliability, no commutation sparks, and low mechanical noise. They are generally used in larger aircraft with greater payloads, allowing for a wider range of applications.

[0004] Currently, the motors in drones usually do not have shock-absorbing structures. The motors are usually fixed inside the drone or installed inside the drone with screws.

[0027] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following combination Figures 1 to 2 The utility model describes a UAV motor vibration reduction mechanism and a UAV.

[0029] Motor 2, a device that converts electrical energy into mechanical energy, is installed on the aircraft's mounting plate to power the aircraft. With the development of drone technology, requirements for vibration control are becoming increasingly stringent. Excessive vibration from motor 2 poses a significant risk to the drone's structure, not only generating loud noise but also affecting the stability of the aircraft body 1. Therefore, designing a vibration-damping structure to reduce the vibration from motor 2 to the aircraft body 1 is crucial. However, existing aircraft vibration-damping structures are heavy and bulky, making them difficult to adapt to different aircraft.

[0030] In order to solve the above problems, Figure 1 and Figure 2 As shown, the drone motor vibration reduction mechanism of the present invention includes a vibration reduction assembly 4 and a motor mounting plate 3. The motor mounting plate 3 is adapted to mount a motor 2. Specifically, the motor 2 used in the drone is fixedly mounted on the motor mounting plate 3. For example, the motor 2 is secured to the motor mounting plate 3 via fasteners.

[0031] The shock-absorbing assembly 4 includes a bolt 42, a nut 43, and a shock-absorbing pad 41. The shock-absorbing pad 41 is provided with a through-hole extending along its axial direction. For example, the shock-absorbing pad 41 is cylindrical, with a circular through-hole provided at the center axis of the shock-absorbing pad 41. The through-hole extends in the same direction as the height of the shock-absorbing pad 41. In addition, the outer side of the shock-absorbing pad 41 is provided with an annular mounting groove, and the motor mounting plate 3 is inserted into the mounting groove to achieve a stable connection between the motor mounting plate 3 and the shock-absorbing pad 41.

[0032] It is particularly important to point out that the motor mounting plate 3 can be assembled from multiple sub-parts. For example, the motor mounting plate 3 includes a first motor mounting plate and a second motor mounting plate. The first motor mounting plate is provided with a semicircular groove, and the second motor mounting plate is provided with a semicircular groove. In this way, the motor mounting plate 3 can be easily installed in the mounting groove.

[0033] In addition, the drone body 1 is provided with a first mounting hole, which is coaxially arranged with the through-hole. The bolt 42 is suitable for being sequentially passed through the first mounting hole and the through-hole and connected with the nut 43 so that the shock-absorbing pad 41 can be fixed to the body 1.

[0034] In an embodiment of the present invention, the motor 2 is mounted on the motor mounting plate 3, and the motor mounting plate 3 is connected to the body 1 of the drone by means of a shock-absorbing pad 41, thereby realizing the connection between the motor 2 and the body 1 of the drone. The shock-absorbing pad 41 can effectively isolate the vibration transmitted from the motor 2 to the motor mounting plate 3, both in the axial direction and the radial direction, and the shock-absorbing pad 41 and the motor mounting plate 3 are elastically connected in multiple directions, so that high-frequency vibrations can also be better isolated.

[0035] In some embodiments, as Figure 2 As shown, the shock-absorbing pad 41 is arranged in a split type, and the shock-absorbing pad 41 includes a first shock-absorbing pad 411 and a second shock-absorbing pad 412 arranged coaxially. A protrusion is provided on the side of the first shock-absorbing pad 411 facing the second shock-absorbing pad 412. The first shock-absorbing pad 411 is abutted against the side of the second shock-absorbing pad 412 away from the nut 43 through the protrusion. The first shock-absorbing pad 411, the protrusion and the second shock-absorbing pad 412 are surrounded to form an installation groove.

[0036] The first and second shock-absorbing pads 411 and 412 have the same shape and outer diameter, and are both provided with mounting holes. Furthermore, the raised portion may be cylindrical, and a mounting hole is also provided at the central axis of the raised portion.

[0037] In actual application, the bolt 42 can be sequentially passed through the first mounting hole, the mounting hole of the first shock-absorbing pad 411 , the mounting hole of the protrusion, and the mounting hole of the second shock-absorbing pad 412 and connected to the nut 43 .

[0038] In some embodiments, as Figure 2 As shown, the motor mounting plate 3 is provided with a second mounting hole, and the protrusion is installed in the second mounting hole, so that the motor mounting plate 3 can be installed in the mounting slot. Among them, the second mounting hole needs to be compatible with the protrusion, and the thickness of the motor mounting plate 3 is the same as the height of the protrusion.

[0039] It is particularly important to point out that during installation, the motor mounting plate 3 can be first mounted on the raised portion through the second mounting hole, and finally the first shock-absorbing pad 411, the second shock-absorbing pad 412 and the body 1 can be assembled to achieve the connection between the motor mounting plate 3 and the body 1.

[0040] In some embodiments, both the first and second shock-absorbing pads 411, 412 are rubber shock-absorbing pads 41. Rubber materials have much higher internal damping than metal, providing better isolation from high-frequency vibrations. Furthermore, rubber materials offer excellent shock absorption, wear resistance, and elastic recovery capabilities.

[0041] In some embodiments, as Figure 2 As shown, the shock absorbing assembly 4 also includes a sleeve 44, the length of which is less than or equal to the length of the through-hole. The sleeve 44 is coaxially arranged in the through-hole, and the bolt 42 is suitable for being sequentially passed through the first mounting hole and the sleeve 44 and connected with the nut 43.

[0042] It should be noted that the material of the sleeve 44 is different from that of the shock-absorbing pad 41. For example, the sleeve 44 is made of metal. The length of the sleeve 44 is roughly the same as the length of the hole.

[0043] In actual application, when the nut 43 is used to tighten the shock-absorbing pad 41, the setting of the sleeve 44 can control the number of rotations of the nut 43 relative to the screw of the bolt 42, thereby achieving the purpose of controlling the compression amount of the shock-absorbing pad 41.

[0044] In some embodiments, as Figure 2 As shown, the screw rod of the bolt 42 is provided with a tail hole, and the side of the nut 43 facing away from the shock-absorbing pad 41 is provided with at least one pin groove. The shock-absorbing assembly 4 also includes a cotter pin 46, which is passed through the pin groove and the tail hole.

[0045] The nut 43 can be provided with multiple pin slots, which are symmetrically arranged along the center of the nut 43. Providing multiple pin slots on the nut 43 to mate with the tail hole of the screw allows the nut 43 to be fixed at different positions, facilitating the installation of the cotter pin 46. For example, the nut 43 body is provided with six pin slots, and the nut 43 adopts a common hexagonal nut configuration. The six pin slots are symmetrically arranged along the center of the nut 43, with one pin slot opened every 60°.

[0046] It should be noted that the cotter pin 46 cooperates with the pin groove of the nut 43 and the tail hole of the screw to prevent the nut 43 and the screw from rotating relative to each other.

[0047] In some embodiments, as Figure 2 As shown, the shock absorbing assembly 4 further includes a gasket 45 having a through hole. The gasket 45 is disposed on the side of the shock absorbing pad 41 facing away from the body 1. The bolt 42 is adapted to be sequentially passed through the first mounting hole, the through hole, and the through hole and connected to the nut 43. The diameter of the through hole is smaller than the outer diameter of the sleeve 44.

[0048] It should be noted that the gasket 45 is arranged on the side of the second shock-absorbing pad 412 away from the first shock-absorbing pad 411. In this way, when the nut 43 is connected to the screw, the contact area between the nut 43 and the second shock-absorbing pad 412 can be increased, thereby ensuring the stability of the connection and increasing the balance of force on the second shock-absorbing pad 412.

[0049] In some embodiments, as Figure 1 and Figure 2 As shown, there are multiple shock absorbing components 4, and the multiple shock absorbing components 4 are arranged in a circle.

[0050] For example, the number of the shock absorbing components 4 is six, and the six shock absorbing components 4 are arranged in a circle, so that a stable and reliable connection between the machine body 1 and the motor mounting plate 3 can be ensured.

[0051] In some embodiments, as Figure 1 and Figure 2As shown, the shock absorbing assembly 4 further includes a first washer, which is located between the head of the bolt 42 and the body 1. It should be noted that by providing the first washer between the head of the bolt 42 and the body 1, not only the shock absorbing effect is enhanced, but also the stability of the installation is improved.

[0052] In addition, the second washer is located between the side of the shock absorbing pad 41 away from the body 1 and the nut 43. In other words, by arranging the second washer between the washer 45 and the nut 43, the stability of the installation is improved.

[0053] In addition, if Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides a drone, comprising: a body 1, a motor 2, and a drone motor shock-absorbing mechanism. The motor 2 is mounted on a motor mounting plate 3. Bolts 42 are sequentially inserted through the first mounting hole and the through-hole and connected to nuts 43, thereby securing a shock-absorbing pad 41 to the body 1.

[0054] Specifically, since the drone includes the drone motor shock absorption mechanism as described above, the specific structure of the drone motor shock absorption mechanism refers to the above embodiment, and the drone shown in this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the above technical solutions, which will not be repeated here.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
