Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a power motor set for a T-series plant protection unmanned aerial vehicle. Background Art

[0002] With the increasing maturity of aviation technology, some brushless power motor sets are applied to the relatively demanding agricultural plant protection industry to provide power for unmanned aerial vehicles. This requires the power sets on such equipment to have the characteristics of providing large load capacity, high power, high efficiency, low weight, small space, easy assembly, and easy maintenance. The existing such power motor sets generally adopt the method of self-assembling single-piece components such as propellers + motors + electronic speed controllers + carbon tube fixing seats + lamp covers + other auxiliary accessories (the motor is a brushless outer rotor motor, and the electronic speed controller is an electronic controller for brushless motors), that is, customers purchase the components required for the above power motor set by themselves for self-assembly. This method is very time-consuming and laborious, with high comprehensive costs, poor assembly effects, low efficiency, poor coordination between different components, and easy assembly errors. The purchased components such as carbon tube fixing seats are generally general-purpose components without some limiting and installation protection measures. When installing the overall power motor set of a multi-rotor unmanned aerial vehicle later, due to no limits, the installation distances of each axis are different and it is also very difficult to ensure installation on the same horizontal line. When the aircraft takes off, it is easy to be skewed or vibrate greatly due to installation defects, affecting flight safety. There is no direct installation and fixing position for the electronic speed controller component. Customers need to install and fix it by themselves with screws or straps. The fixing effect is poor and it is not safe. Moreover, due to the large power consumption of its electronic speed controller component, it generates a lot of heat, has poor heat dissipation, and is easy to cause poor overall use efficiency of the machine. The installation of each loose part also requires external wiring and welding of the motor and electronic speed controller circuits by oneself. It is easy for the external wiring to be damaged due to environmental factors, which is not conducive to flight safety. And due to the poor coordination between the loose parts and the lack of complete optimization, during the use of the power set, it is easy to cause phenomena such as crashing and crashing of the aircraft due to internal incoordination. Moreover, once the above phenomena occur, it is difficult to directly disassemble some damaged parts in the middle and find suitable parts for replacement and repair, affecting the efficiency of on-site operations and the use cost of customers. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a power motor set for a T-series plant protection unmanned aerial vehicle.

[0006] Preferably, the carbon tube fixing seat further includes a base provided at the bottom of the cylinder body and integrally formed with the cylinder body. The base is divided into two parts by a transverse gap penetrating through it; the transverse gap is communicated with the accommodating space; the two parts of the base are locked tightly by a plurality of horizontally arranged screws.

[0007] Preferably, the electronic speed control assembly includes an electronic speed control bottom shell, an electronic speed control upper cover provided on and connected to the electronic speed control bottom shell, and an electronic speed control board installed in the space formed after the two are combined; a heat dissipation portion located on one side of the motor is provided on the upper surface of the electronic speed control upper cover.

[0008] Preferably, the heat dissipation portion includes several columns of heat dissipation fins. Each column of heat dissipation fins includes several heat dissipation fin monomers, and there is a gap between adjacent two heat dissipation fin monomers.

[0009] Preferably, an opening is provided at the upper end of the pipe support. Two connecting blocks are respectively provided on the outer walls on both sides of the opening. Two connecting seats corresponding to the two connecting blocks are respectively provided on both side surfaces of the electronic speed control bottom shell.

[0010] Preferably, a buckle member is further included; one side of the buckle member is buckled to the electronic speed control bottom shell, and the other side is fixedly connected to the carbon tube fixing seat.

[0011] Preferably, two connecting plates are provided at one end of the carbon tube fixing seat connected to the electronic speed control assembly. The two connecting plates extend under the other side of the buckle member and are fixedly connected to the buckle member by screws.

[0012] Technical effects: With the above structure:

[0013] 1. All the assembled parts are integrally designed and assembled.

[0027] As Figure 3 shown in Figure 3 , the carbon tube fixing seat 1 further includes a base 103 provided at the bottom of the cylinder body and integrally formed with the cylinder body. The base is divided into two parts by a transverse gap 104 penetrating it; the transverse gap is communicated with the accommodation space 101; the two parts of the base 103 are locked by a plurality of horizontally arranged screws to fix the carbon tube.

[0028] As Figure 4 shown in Figure 4 , the electronic speed control component 4 includes an electronic speed control bottom case 401, an electronic speed control upper cover 402 provided on and connected to the electronic speed control bottom case, and an electronic speed control board 403 installed in the space formed after the combination of the two; a heat dissipation portion 6 located on one side of the motor 2 is provided on the upper surface of the electronic speed control upper cover 402; the height of the heat dissipation portion here is approximately the same as that of the motor.
