请一并参阅图1及图2，本发明实施方式的供电机构100包括电动装置10、发电装置20和输出导线30。Please refer to FIG. 1 and FIG. 2 together. The power supply mechanism 100 according to the embodiment of the present invention includes an electric device 10, a power generation device 20, and an output wire 30.
电动装置10包括电动定子11和相对于电动定子11可转动的电动转子12。发电装置20包括发电定子21和发电转子22，发电转子22相对于发电转子22可转动，发电转子22与电动转子12固定连接，使得电动转子12带动发电转子22一起转动。发电转子22设有用于承载雷达天线装置200的承载部40。The electric device 10 includes an electric stator 11 and an electric rotor 12 that is rotatable with respect to the electric stator 11. The power generating device 20 includes a power generating stator 21 and a power generating rotor 22. The power generating rotor 22 is rotatable relative to the power generating rotor 22. The power generating rotor 22 is fixedly connected to the electric rotor 12 so that the electric rotor 12 drives the power generating rotor 22 to rotate together. The power generating rotor 22 is provided with a supporting portion 40 for supporting the radar antenna device 200.
输出导线30与发电转子22电连接，输出导线30用于输出电能给雷达天线装置200。The output wire 30 is electrically connected to the power generating rotor 22. The output wire 30 is used to output electric energy to the radar antenna device 200.
电动转子12转动时带动发电转子22和输出导线30一并转动，以使发电转子22相对于发电定子21做切割磁场线转动而产生感应电能，并通过输出导线30输送给雷达天线装置200。When the electric rotor 12 rotates, the power generating rotor 22 and the output wire 30 are rotated together, so that the power generating rotor 22 rotates with respect to the power generating stator 21 by cutting magnetic field lines to generate induced power, and is transmitted to the radar antenna device 200 through the output wire 30.
本发明实施方式的供电机构100中，由于发电转子22做切割磁场线而产生电能，不仅可以防止输出导线30产生线缠绕的问题，还可以防止发电转子22磨损，在提高供电机构100寿命的同时可以为雷达天线装置200持续地提供电能。In the power supply mechanism 100 according to the embodiment of the present invention, because the power generating rotor 22 cuts the magnetic field lines to generate electric energy, not only the problem of wire winding of the output conductor 30 can be prevented, but also the power generating rotor 22 can be prevented from abrasion. The radar antenna device 200 can be continuously supplied with power.
具体地，电动装置10相当于一个电动机，电动定子11和电动转子12之间的结构可以为无电刷结构。或者说，电动装置10可以为无刷电动装置。当然，电动装置10也可以为有刷电动装置或空心杯电动装置。Specifically, the electric device 10 corresponds to one electric motor, and the structure between the electric stator 11 and the electric rotor 12 may be a brushless structure. In other words, the electric device 10 may be a brushless electric device. Of course, the electric device 10 may also be a brushed electric device or a hollow cup electric device.
电动装置10为将电能转换为机械能的装置。具体地，供电机构100还包括输入导线31，输入导线31用于为电动装置10输入电能，电动装置10接电后， 电动装置10产生励磁电场，电场驱动电动转子12旋转，从而将电能转换为旋转的机械能。可以理解，电动机的工作原理为本领域技术人员熟知，因此，在此不再详细赘述。The electric device 10 is a device that converts electrical energy into mechanical energy. Specifically, the power supply mechanism 100 further includes an input wire 31. The input wire 31 is used to input electric energy to the electric device 10. After the electric device 10 is connected, the electric device 10 generates an exciting electric field. The electric field drives the electric rotor 12 to rotate, thereby converting the electric energy into Rotating mechanical energy. It can be understood that the working principle of the motor is well known to those skilled in the art, and therefore, it will not be described in detail here.
发电装置20为将机械能转换为电能的装置，具体地，发电转子22转动后，发电转子22做切割磁场线运动，从而产生电能，电能从输出导线30输出以为雷达天线装置200供电。发电机的工作原理为本领域技术认为熟知，在此不再详细赘述。The power generating device 20 is a device that converts mechanical energy into electrical energy. Specifically, after the power generating rotor 22 rotates, the power generating rotor 22 performs cutting magnetic field line motion to generate electrical energy, and the electrical energy is output from the output wire 30 to power the radar antenna device 200. The working principle of the generator is well known to those skilled in the art and will not be described in detail here.
发电装置20相当于一个发电机，因此，发电装置20可以为有刷发电装置、无刷发电装置或空心杯发电装置。The power generating device 20 is equivalent to a generator, and therefore, the power generating device 20 may be a brushed power generating device, a brushless power generating device, or a hollow cup power generating device.
输出导线30例如为漆包线。输出导线30的数量例如为两根。输出导线30的横截面积大小可以根据实际需求具体设定。例如，需要输出的感应电能较大时，可以采用横截面积较大的输出导线30以提高电能的输送效率。The output lead 30 is, for example, an enameled wire. The number of output wires 30 is, for example, two. The cross-sectional area of the output wire 30 can be specifically set according to actual needs. For example, when a large amount of induced electrical energy needs to be output, an output wire 30 having a large cross-sectional area may be used to improve the transmission efficiency of electrical energy.
发电转子22与电动转子12例如可以通过焊接、过盈配合等方式固定在一起，从而实现发电转子22随着电动转子12一并转动。The power generating rotor 22 and the electric rotor 12 may be fixed together, for example, by welding, interference fit, or the like, so that the power generating rotor 22 is rotated together with the electric rotor 12.
雷达天线装置200是辐射和接收电磁波的设备，雷达天线装置200承载在承载部40上，使得雷达天线装置200可以随着发电转子22做360度旋转运动，从而可以全方位地辐射和接收信号。The radar antenna device 200 is a device for radiating and receiving electromagnetic waves. The radar antenna device 200 is carried on the bearing portion 40, so that the radar antenna device 200 can perform a 360-degree rotating movement with the power generating rotor 22, thereby radiating and receiving signals in all directions.
可以理解，可以通过控制向电动装置10输送的电能大小从而实现控制发电转子22的转速，从而达到控制雷达天线装置200的转动速度的效果。例如，雷达天线装置200的转动速度可以为1r/s(转/秒)。It can be understood that, by controlling the amount of electric energy transmitted to the electric device 10, the rotation speed of the power generating rotor 22 can be controlled, thereby achieving the effect of controlling the rotation speed of the radar antenna device 200. For example, the rotation speed of the radar antenna device 200 may be 1 r / s (revolutions per second).
雷达天线装置200可以通过螺钉等紧固件固定在承载部40上。承载部40的结构与雷达天线装置200相适应。例如，承载部40开设有用于安装雷达天线装置200的螺纹孔。The radar antenna device 200 may be fixed to the bearing portion 40 by a fastener such as a screw. The structure of the carrier 40 is adapted to the radar antenna device 200. For example, the bearing portion 40 is provided with a screw hole for mounting the radar antenna device 200.
在某些实施方式中，电动定子11设置在电动转子12内，发电转子22固定在电动转子12的端部并包括发电线圈绕组221，发电定子21围绕发电转子22设置并包括发电磁铁211。In some embodiments, the electric stator 11 is disposed in the electric rotor 12, the power generating rotor 22 is fixed at an end of the electric rotor 12 and includes a power generating coil winding 221, and the power generating stator 21 is disposed around the power generating rotor 22 and includes a power generating magnet 211.
如此，发电磁铁211形成有磁场，发电线圈绕组221转动时可以做切割磁场线运动，从而产生感应电能。In this way, the power generating magnet 211 forms a magnetic field, and when the power generating coil winding 221 rotates, it can perform cutting magnetic field line motion, thereby generating induced power.
图1及图2的示例所示，发电转子22固定在电动转子12的上端。可以理解，在其他实施方式中，发电转子22可以固定在电动转子12的下端。As shown in the examples of FIGS. 1 and 2, the power generating rotor 22 is fixed to the upper end of the electric rotor 12. It can be understood that, in other embodiments, the power generating rotor 22 may be fixed at the lower end of the electric rotor 12.
在图3的示例中，电动定子11a设置在电动转子12a内，发电转子22a围绕固定在电动转子12a上并包括发电线圈绕组(图未示)，发电定子21a围绕发电转子22a设置并包括发电磁铁211a。或者说，供电机构100a从其内部向外依次包括电动定子11a、电动转子12a、发电转子22a和发电定子21a。In the example of FIG. 3, the electric stator 11a is provided in the electric rotor 12a, the power generating rotor 22a is fixed around the electric rotor 12a and includes a power generating coil winding (not shown), and the power generating stator 21a is provided around the power generating rotor 22a and includes power generating magnet 211a. In other words, the power supply mechanism 100a includes an electric stator 11a, an electric rotor 12a, a power generating rotor 22a, and a power generating stator 21a in this order from the inside to the outside.
在图4的示例中，电动转子12b设置在电动定子11b内，发电转子22b固定在电动转子12b内部并包括发电线圈绕组(图未示)，发电定子21b设置在发电转子22b内。或者说，供电机构100b从其内部向外依次包括发电定子21b、发电转子22b、电动转子12b和电动定子11b。In the example of FIG. 4, the electric rotor 12 b is provided in the electric stator 11 b, the power generating rotor 22 b is fixed inside the electric rotor 12 b and includes a power generating coil winding (not shown), and the power generating stator 21 b is provided in the power generating rotor 22 b. In other words, the power supply mechanism 100b includes a power generating stator 21b, a power generating rotor 22b, an electric rotor 12b, and an electric stator 11b in this order from the inside to the outside.
当然，发电定子21、发电转子22、电动转子12和电动定子11的位置布局方式不限于以上所讨论的情况，只要使得电动转子12带动发电转子22转动及输出导线30一并转动，使得输出导线30在旋转的同时输出电能即可。Of course, the position layout of the power generating stator 21, the power generating rotor 22, the electric rotor 12, and the electric stator 11 is not limited to the situation discussed above, as long as the electric rotor 12 drives the power generating rotor 22 to rotate and the output lead 30 rotates together, so that the output lead 30 can output electrical energy while rotating.
请再次参阅图1及图2，在某些实施方式中，电动定子11包括电动线圈绕组111，电动转子12包括电动外壳121和电动磁铁122，电动外壳121包括顶壁123和侧壁124，侧壁124自顶壁123的边缘延伸且围绕电动线圈绕组111，电动磁铁122固定在侧壁124的内侧。Please refer to FIG. 1 and FIG. 2 again. In some embodiments, the electric stator 11 includes an electric coil winding 111, the electric rotor 12 includes an electric casing 121 and an electric magnet 122, and the electric casing 121 includes a top wall 123 and a side wall 124. The wall 124 extends from the edge of the top wall 123 and surrounds the electric coil winding 111, and the electric magnet 122 is fixed inside the side wall 124.
发电转子22固定在顶壁123的外侧，发电定子21围绕发电转子22设置。The power generating rotor 22 is fixed outside the top wall 123, and the power generating stator 21 is provided around the power generating rotor 22.
如此，电动线圈绕组111通电后可以使得电动转子12绕电动线圈绕组111转动。电动外壳121不仅有利于电动磁铁122安装，还可以隔离电动线圈绕组111和发电转子22，避免电动线圈绕组111和发电转子22干涉。In this way, after the electric coil winding 111 is energized, the electric rotor 12 can be caused to rotate around the electric coil winding 111. The electric housing 121 not only facilitates the installation of the electric magnet 122, but also isolates the electric coil winding 111 and the power generating rotor 22 to avoid interference between the electric coil winding 111 and the power generating rotor 22.
具体地，电动外壳121可以采用金属材料制成，例如，电动外壳121的材料为铝合金。电动外壳121可以为顶壁123和侧壁124形成的一体结构。电动磁铁122可以通过粘接的方式固定在侧壁124的内侧。发电转子22可以通过焊 接、卡接、粘接等固定方式固定在顶壁123的外侧。Specifically, the electric housing 121 may be made of a metal material, for example, the material of the electric housing 121 is an aluminum alloy. The electric housing 121 may be an integrated structure formed by the top wall 123 and the side wall 124. The electromagnet 122 can be fixed on the inner side of the side wall 124 by an adhesive method. The power generating rotor 22 may be fixed to the outside of the top wall 123 by a fixing method such as welding, snapping, or bonding.
在某些实施方式中，电动转子12还包括自顶壁123延伸的转轴125，转轴125穿设电动线圈绕组111并伸出至电动外壳121外。如此，转轴125可以连接外部元件，从而带动外部元件随着电动转子12一并转动。In some embodiments, the electric rotor 12 further includes a rotating shaft 125 extending from the top wall 123. The rotating shaft 125 passes through the electric coil winding 111 and protrudes out of the electric housing 121. In this way, the rotating shaft 125 can be connected with external components, thereby driving the external components to rotate along with the electric rotor 12.
本实施方式中，转轴125自顶壁123向远离承载部40的方向延伸。在其他实施方式中，转轴125可以省略以使供电机构100的结构更加简单。In this embodiment, the rotating shaft 125 extends from the top wall 123 in a direction away from the bearing portion 40. In other embodiments, the rotating shaft 125 may be omitted to make the structure of the power supply mechanism 100 simpler.
在某些实施方式中，发电定子21包括筒状壳体212，筒状壳体212的下部围绕电动外壳121，筒状壳体212的上部围绕发电转子22，发电磁铁211固定在筒状壳体212的上部内侧。In some embodiments, the power generating stator 21 includes a cylindrical case 212, the lower portion of the cylindrical case 212 surrounds the electric housing 121, the upper portion of the cylindrical case 212 surrounds the power generating rotor 22, and the power generating magnet 211 is fixed to the cylindrical case The upper inside of 212.
如此，发电定子21的筒状壳体212可以将发电转子22和电动转子12围绕，使得供电机构100的整体结构更加简单，并且可以减少电动转子12和发电转子22受到的物理冲击。In this way, the cylindrical casing 212 of the power generating stator 21 can surround the power generating rotor 22 and the electric rotor 12, so that the overall structure of the power supply mechanism 100 is simpler, and the physical impact on the electric rotor 12 and the power generating rotor 22 can be reduced.
筒状壳体212可以采用金属材料或非金属材料支撑，例如筒状壳体212的材料为不锈钢。又如，筒状壳体212的材料为塑料。发电磁铁211可以为永磁铁块，发电磁铁211例如通过粘接的方式固定在筒状壳体212的上部内侧。The cylindrical case 212 may be supported by a metallic material or a non-metallic material. For example, the material of the cylindrical case 212 is stainless steel. As another example, the material of the cylindrical casing 212 is plastic. The power generating magnet 211 may be a permanent magnet block, and the power generating magnet 211 is fixed to the inside of the upper portion of the cylindrical case 212 by, for example, an adhesive method.
进一步地，筒状壳体212的内侧向内延伸形成有凸缘213，发电磁铁211固定在凸缘213上。如此，凸缘213可以支撑发电磁铁211，提高发电磁铁211与筒状壳体212连接的稳定性。Further, a flange 213 is formed to extend inward of the cylindrical case 212, and the power generating magnet 211 is fixed on the flange 213. In this way, the flange 213 can support the power generating magnet 211 and improve the stability of the connection between the power generating magnet 211 and the cylindrical case 212.
较佳地，凸缘213与筒状壳体212为一体结构。例如，可以将筒状的零件切削加工，从而在筒状的零件内部形成凸缘213。Preferably, the flange 213 and the cylindrical casing 212 are an integrated structure. For example, a cylindrical part may be cut to form a flange 213 inside the cylindrical part.
在某些实施方式中，供电机构100包括固定基座50，电动定子11和筒状壳体212均固定在固定基座50上。如此，固定基座50为供电机构100的载体，不仅可以固定电动定子11和筒状壳体212，还方便供电机构100整体安装于外部设备上。In some embodiments, the power supply mechanism 100 includes a fixed base 50, and the electric stator 11 and the cylindrical housing 212 are both fixed on the fixed base 50. In this way, the fixed base 50 is a carrier of the power supply mechanism 100, which can not only fix the electric stator 11 and the cylindrical casing 212, but also facilitate the overall installation of the power supply mechanism 100 on external equipment.
在图2的示例中，固定基座50整体呈圆盘状，固定基座50的尺寸大于筒状壳体212的尺寸。固定基座50可以采用金属等强大较大的材料制成，以为电 动定子11和筒状壳体212提供稳定地支撑。In the example of FIG. 2, the fixed base 50 has a disc shape as a whole, and the size of the fixed base 50 is larger than that of the cylindrical case 212. The fixed base 50 may be made of a strong and large material such as metal to provide stable support for the electric stator 11 and the cylindrical case 212.
进一步地，筒状壳体212的底部周缘向外延伸形成有凸边214，凸边214抵靠固定在固定基座50上。如此，凸边214可以增加筒状壳体212与固定基座50的连接面积，提高筒状壳体212与固定基座50的连接的稳定性。Further, a convex edge 214 is formed on the peripheral edge of the bottom of the cylindrical casing 212, and the convex edge 214 is abutted and fixed on the fixed base 50. In this way, the convex edge 214 can increase the connection area between the cylindrical case 212 and the fixed base 50, and improve the stability of the connection between the cylindrical case 212 and the fixed base 50.
请参阅图1，凸边214形成有第一通孔215，固定基座50形成有与第一通孔215对应的第二通孔51。第一通孔215和/或第二通孔52可以为螺纹孔，这样可以使用螺钉等紧固件(图未示)穿过第一通孔215和第二通孔51从而将筒状壳体212紧固在固定基座50上。Referring to FIG. 1, the protruding edge 214 is formed with a first through hole 215, and the fixed base 50 is formed with a second through hole 51 corresponding to the first through hole 215. The first through hole 215 and / or the second through hole 52 may be threaded holes. In this way, a fastener such as a screw (not shown) may be used to pass through the first through hole 215 and the second through hole 51 to form the cylindrical housing. 212 is fastened to the fixed base 50.
在某些实施方式中，固定基座50包括基板52和固定部53，固定部53自基板52向上延伸，电动定子11围绕固定在固定部53上。如此，固定部53有利于安装电动定子11。In some embodiments, the fixed base 50 includes a base plate 52 and a fixed portion 53.
