[0002] In recent years, with the rapid development of cities and the rapid increase in the population of large cities, existing passenger transportation can no longer meet people's needs. In daily life, short-distance transportation or passenger transport often uses ground transportation such as buses, cars, and trucks. These modes of transportation are often restricted by ground roads and often experience traffic congestion. In terms of aircraft, manned aircraft are suitable for short-distance transportation and will be widely used and developed now and in the future.

[0003] The existing multi-rotor aircraft arm joint bracket cannot adjust the motor installation angle at will. If the motor needs to be replaced, the entire bracket must be replaced to match the motor installation point, which is time-consuming and labor-intensive, affecting installation efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0020] See also Figure 1-2 A mounting structure for an arm bracket and a motor includes an arm bracket 3, one side of the arm bracket 3 is connected to a front arm 1, the arm bracket 3 is connected to the front arm 1 through a front arm ear 2, and the position of the front arm 1 can be adjusted through the front arm ear 2, the other side of the arm bracket 3 is connected to a rear arm 6, the arm bracket 3 is connected to the rear arm 6 through a rear arm ear 5, and the position of the rear arm 6 can be adjusted through the rear arm ear 5, and a motor mounting seat 4 is also provided on the arm bracket 3.

[0021] A first screw hole is provided on one side of the front arm ear piece 2, and the front arm 1 is mechanically connected to the arm bracket 3 through the first screw hole, and the other side of the front arm ear piece 2 is fixedly connected to the front arm 1. The front arm ear piece 2 can be replaced according to the required position of the front arm 1, and the position of the front arm 1 can be adjusted; a second screw hole is provided on one side of the rear arm ear piece 5, and the rear arm 6 is mechanically connected to the arm bracket 3 through the second screw hole, and the other side of the rear arm ear piece 5 is fixedly connected to the rear arm 6. The rear arm ear piece 5 can be replaced according to the required position of the rear arm 6, and the position of the rear arm 6 can be adjusted.

[0022] A third screw hole is also provided on the arm bracket 3, and a front ear piece a and a rear ear piece b are provided on the motor mounting base 4. The front ear piece a and the rear ear piece b are mechanically connected to the arm bracket 3 through the third screw hole; the height of the front ear piece a is greater than the rear ear piece b, or the height of the front ear piece a is equal to the rear ear piece b, or the height of the front ear piece a is less than the rear ear piece b, which is used to be determined according to the installation angle of the motor.

[0023] Working principle: The arm bracket 3 can meet the requirements of different motor installation sizes by replacing the motor mounting base 4. Figure 1 、 Figure 2 As shown, the height difference between the front ear piece a and the rear ear piece b is adjusted to achieve the angle deflection requirement of the motor mounting seat 4. For example, the height of the front ear piece a is increased and the height of the rear ear piece b is decreased, and the height of the central axis of the motor mounting seat 4 is always kept unchanged. In this way, the motor mounting seat 4 will have a height difference compared to the horizontal plane, which meets the motor installation angle requirement. At the same time, because the height of the central axis of the motor mounting seat 4 remains unchanged, the height difference requirement between multiple motors is met.
