Description

Technical Field

[0001] The present application belongs to the technical field of cross-country drones, and in particular, relates to a cross-country drone motor lead fixing structure using high-temperature resistant enameled wires. Background Art

[0002] In the field of motor technology, especially in the design of brushless motors used in high-performance FPV drones, the application of high-temperature resistant enameled wires is becoming more and more widespread, because its excellent heat resistance effectively improves the operating stability and life of the motor in high-temperature environments. However, in related technologies, when it comes to the connection between high-temperature resistant enameled wires and external circuits (such as power supplies or control systems), a commonly used practice is to connect the enameled wires and silicone wires by welding. Although this method achieves electrical connection to a certain extent, the insulating paint layer of the enameled wires needs to be partially removed during implementation so that the exposed copper conductor can form a reliable welding joint with the silicone wire.

[0003] It is worth noting that due to space constraints, the length of paint stripping is usually limited to about 10 mm. This limitation directly affects the applicability of high-temperature resistant enameled wire in specific application scenarios. Due to the insufficient paint stripping length, it is difficult to achieve a stable and electrical safety-compliant welding connection on the PCB board, thus limiting the wide application of high-temperature resistant enameled wire in precision electronic equipment such as high-end brushless motors of cross-country drones.

[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] For the brushless motor of the traversing machine using high temperature resistant enameled wire, this type of enameled wire is generally connected by welding with silicone wire. This method requires the paint coating of the high temperature resistant enameled wire to be stripped, and the stripping length can generally only reach about 10mm. Due to the limitation of the stripping length, this type of enameled wire is not suitable for the solution of using PCB board outlet. This application aims to achieve the outlet of the PCB board using the high temperature resistant enameled wire motor by adjusting the position of the high temperature resistant enameled wire motor winding and extending the connection length of the high temperature resistant enameled wire, thereby improving the stability, reliability, safety and maintainability of the motor outlet.

[0029] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0030] See also Figures 1 to 6 As shown, an embodiment of the present application provides a structure for fixing the motor output wires of a throttle motor using high temperature resistant enameled wires, including: a motor rear cover 10, a PCB board 20, a motor winding 30 and a heat shrink sleeve.

[0031] 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.

[0032] 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 high temperature resistant enameled wire 31 of the motor winding 30 and the welding part 22 are respectively located on opposite sides of the annular fixing part 21. Among them, the upper end of the welding part 22 is used to weld the high temperature resistant enameled wire 31 of the motor winding 30, and the welding 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.

[0033] It should be noted that, since the enameled wire of the present application is a high temperature resistant enameled wire 31, when the high temperature resistant enameled wire 31 is welded to the PCB board 20, the high temperature resistant enameled wire 31 needs to be stripped of paint. Therefore, when the gap d between the motor winding 30 and the PCB board 20 is less than 10 mm, it is necessary to adjust the position of the motor winding 30, that is, to turn the direction of the motor winding 30 180 degrees, so that the high temperature resistant enameled wire 31 and the welding part 22 are respectively located on opposite sides of the annular fixing part 21, so as to extend the connection length of the high temperature resistant enameled wire 31, so that the high temperature resistant enameled wire 31 is wound around the motor back cover 10 for half a circle, and then connected to the PCB board 20, so as to realize the PCB board outlet of the high temperature resistant enameled wire 31.

[0034] The heat shrink sleeve is used to cover the high temperature resistant enameled wire 31 to prevent short circuit.

[0035] In the above-mentioned structure for fixing the motor lead of a thru-machine using high-temperature resistant enameled wire, the PCB board 20 is fixed on the mounting mating surface 11 of the motor rear cover 10 through the annular fixing portion 21, the high-temperature resistant enameled wire 31 and the welding portion 22 are respectively located on opposite sides of the annular fixing portion 21, and the upper and lower sides of the welding portion 22 of the PCB board 20 are respectively used for welding the high-temperature resistant enameled wire 31 of the motor winding 30 and the motor lead wire 40, which can improve the stability, reliability, and safety of the motor lead wire and facilitate maintenance. The soldering pad 221 at the lower end of the soldering portion 22 is not only convenient for welding the motor lead wire 40, but also can easily replace the lead wires of different specifications.

[0036] 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.
