Description

Technical Field

[0001] This utility model belongs to the field of drone motor installation technology, and more specifically, it relates to an external mounting structure for a brushless motor for drones. Background Technology

[0002] The external mounting structure for brushless motors in drones enables functions such as stable motor mounting, vibration and noise reduction, protection, and good electrical connection, thereby ensuring the normal flight of the drone.

[0003] The usual method for installing brushless motors is to install and fix the end cap of the brushless motor to the corresponding mounting structure. This involves using screws, clips, or other similar connectors to tightly connect the end cap of the brushless motor to the pre-designed mounting structure.

[0004] However, this conventional fixing method has significant limitations. It merely connects the mounting structure to the brushless motor end cap, without providing comprehensive and effective assurance of the overall stability between the brushless motor and the mounting structure. Because relying solely on the end cap to support the connection between the brushless motor and the mounting structure is prone to loosening and displacement during actual drone flight, especially when encountering strong airflow, frequent attitude adjustments, or other situations that may cause vibration or shaking. This makes it difficult to guarantee the stable installation of the brushless motor and the mounting structure, potentially adversely affecting the drone's normal flight performance and flight safety. Utility Model Content

[0005] This disclosure relates to an external mounting structure for a brushless motor used in unmanned aerial vehicles (UAVs), which addresses the problem mentioned in the background art that, during actual flight of a UAV, when it encounters strong airflow impacts, frequent attitude adjustments, or other situations that may cause vibration or shaking, the connection method that relies solely on the end cap to the mounting structure is prone to loosening and displacement.

[0006] The purpose and effect of this utility model's external mounting structure for a brushless motor in a drone are achieved through the following specific technical means:

[0007] In a first aspect, this disclosure provides an external mounting structure for a brushless motor used in unmanned aerial vehicles (UAVs), comprising: a battery casing, on which a protective frame is mounted; a protective top frame is mounted on the top of the protective frame; the battery casing further comprising: a motor rotor, which is rotatably disposed inside the battery casing; and a mounting base, which is designed in a conical shape and is fixedly mounted on the top of the motor rotor.

[0008] As a preferred embodiment of this utility model, the battery casing further includes: a motor end cover, which is fixedly mounted on the bottom of the battery casing; and four fixing holes, which are arranged in a circular array on the bottom of the motor end cover.

[0009] As a preferred embodiment of this utility model, the protective frame further includes: a fixed side frame, which is designed with an arc-shaped frame structure and has four fixed side frames, which are integrally arranged in a circular array on the outside of the protective frame; and a fixed base, which is designed with an L-shaped base structure and has four fixed bases, which are integrally arranged in a circular array on the bottom of the protective frame.

[0010] As a preferred embodiment of this utility model, the protective frame further includes a fixing joint, which is integrally disposed on one side of the fixing base.

[0011] As a preferred embodiment of this utility model, the protective top frame further includes: mating heads, which are designed with an arc-shaped head structure, and the number of mating heads is set to four. The mating heads are arranged in a ring array and integrally disposed on the outside of the protective top frame; the mating heads are fixedly connected to the fixed side frame by fixing screws.

[0012] As a preferred embodiment of this utility model, the protective top frame further includes: a protective bracket, which is integrally disposed on the top of the protective top frame; and a mating seat, which is designed in the shape of a circular seat and is integrally disposed on one end of the protective bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The protective frame and top shield provide a reliable support framework for the brushless motor. The top shield covers and assists in securing the motor from above, improving its stability. By passing the top shield through the motor rotor and ensuring its protective bracket contacts the battery casing, the motor is secured with screws between the top shield's mating head and the fixed side frame of the protective frame. This combination of the protective frame and top shield effectively surrounds and protects the motor. In addition to improving stability, this enveloping protective structure significantly enhances the brushless motor's collision resistance. When the drone encounters an accidental collision or impact from an external object during flight, the protective system formed by the frame and top shield effectively disperses the impact force, preventing direct and severe damage to the brushless motor, thus ensuring its normal operation and the overall flight performance and safety of the drone.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides an external mounting structure for a brushless motor for a drone, including: a battery casing 1, with a protective frame 2 mounted on the outside of the battery casing 1; a protective top frame 3 mounted on the top of the protective frame 2; the battery casing 1 also includes: a motor rotor 101, which is rotatably disposed inside the battery casing 1; a mounting base 102, which has a conical structure and is fixedly mounted on the top of the motor rotor 101; a motor end cover 103, which is fixedly mounted on the bottom of the battery casing 1; and four fixing holes 104, which are arranged in a circular array on the bottom of the motor end cover 103.

[0025] The protective frame 2 also includes: a fixed side frame 201, which has an arc-shaped frame structure design and four fixed side frames 201 are integrated in a ring array on the outside of the protective frame 2; a fixed base 202, which has an L-shaped base structure design and four fixed bases 202 are integrated in a ring array on the bottom of the protective frame 2; and a fixed connector 203, which is integrated on one side of the fixed base 202.

[0026] The protective top frame 3 also includes: a mating head 301, which has an arc-shaped head structure design, and four mating heads 301 are arranged in a ring array on the outside of the protective top frame 3; the mating head 301 is fixedly connected to the fixed side frame 201 by fixing screws; a protective bracket 302, which is integrally set on the top of the protective top frame 3; and a mating seat 303, which has a circular seat structure design and is integrally set on one end of the protective bracket 302.

[0027] The specific usage and function of this embodiment are as follows: When installing the brushless motor, the protective frame 2 is placed outside the battery casing 1, and the fixing connector 203 at the bottom of the protective frame 2 is adjusted to a suitable position in the fixing hole 104 at the bottom of the motor end cover 103. Then, the brushless motor is initially fixed by inserting fixing screws into the fixing connector 203 and fixing the fixing hole 104. Then, the protective top frame 3 is passed through the motor rotor 101, so that the protective bracket 302 on the protective top frame 3 contacts the outside of the battery casing 1. The brushless motor is then protected by fixing screws between the mating head 301 of the protective top frame 3 and the fixing side frame 201 of the protective frame 2. Finally, the brushless motor is fixedly installed by connecting it to other parts of the drone through the fixing base 202.
