Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of FTVs, and in particular, relates to a FTV motor output line fixing structure. Background Art
[0002] In the field of UAV technology, especially FPV Racing Drone, brushless motors are widely used due to their excellent performance of high speed and fast response. While pursuing extreme speed and maneuverability, this type of motor also puts forward more stringent requirements on the stability of electrical connections. The traditional motor wire connection method generally adopts the method of directly welding the enameled wire to the outlet of the silicone wire. Although this method can provide the necessary electrical connection in the early stage, strong vibration becomes the norm during the high-speed and high-maneuverability flight of the FPV Racing Drone.
[0003] In such a high-dynamic environment for a long time, traditional connection methods gradually expose their inherent defects. Specifically, vibration causes continuous mechanical stress on the solder joints, which in turn accelerates the fatigue and aging process of the solder joints. Over time, this cumulative effect may eventually cause the motor output position to loosen or break, which not only affects flight performance, but may also cause more serious electrical failures or even safety accidents.
[0004] In view of the above problems, a more stable and durable motor cable fixing method is urgently needed to ensure that the brushless motor of the FPV can still maintain reliable electrical connection under high-intensity usage scenarios, thereby improving overall flight stability and safety.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0026] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0028] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0029] See also Figures 1 to 6 As shown, an embodiment of the present application provides a motor line fixing structure for a FTV, including: a motor back cover 10, a PCB board 20 and a motor winding 30.
[0030] The motor rear cover 10 is provided with a mounting mating surface 11 for mounting and fixing the PCB board 20. Specifically, the PCB board 20 includes an annular fixing portion 21 and a welding portion 22 connected to the annular fixing portion 21, the annular fixing portion 21 is sleeved and fixed on the mounting mating surface 11, and a soldering pad 221 is provided at the lower end of the welding portion 22. As an example, the annular fixing portion 21 and the mounting mating surface 11 are fixed by interference fit.
[0031] The motor winding 30 is arranged above the PCB board 20, and the gap d between the motor winding 30 and the PCB board 20 is less than 10 mm. The enameled wire 31 of the motor winding 30 and the welding part 22 are located on the same side of the annular fixing part 21. The upper end of the welding part 22 is used to weld the enameled wire 31 of the motor winding 30, and the pad 221 at the lower end of the welding part 22 is used to weld the motor lead wire 40. As an example, the motor lead wire 40 is a silicone wire.
[0032] It should be noted that, since the enameled wire 31 of the present application is not high temperature resistant, it is not necessary to remove the paint from the enameled wire 31 when welding the enameled wire 31 to the PCB board 20. Therefore, when the gap d between the motor winding 30 and the PCB board 20 is less than 10 mm, the enameled wire 31 of the motor winding 30 and the welding portion 22 can still be arranged on the same side of the annular fixing portion 21.
[0033] In the above-mentioned structure for fixing the motor output line of a thru-boost machine, the PCB board 20 is fixed on the mounting mating surface 11 of the motor rear cover 10 through the annular fixing portion 21, and the upper and lower sides of the welding portion 22 of the PCB board 20 are respectively used to weld the enameled wire 31 of the motor winding 30 and the motor output line 40, which can improve the stability, reliability, and safety of the motor output line and facilitate maintenance. The welding pad 221 at the lower end of the welding portion 22 is not only convenient for welding the motor output line 40, but also can easily replace output lines of different specifications.
[0034] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
