相关申请的交叉参考
本申请要求于2020年11月20日提交中国专利局，申请号为202022716415.2，名称为“一种内置风扇的电子调速器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及风扇技术领域，尤其是一种内置风扇的电子调速器。
背景技术
风扇主要应用在车模、航模、船模、电动无人机等产品上；这些产品工作环境十分复杂，且对产品散热能力要求苛刻，因此要求风扇有更优异的出风能力。
目前，风扇出风能力是模型界所关注的。对于现传统风扇，螺丝锁在电子调速器铝件上，风扇本体外置；其风扇本身有外框，风道不畅通。
申请内容
针对上述现有技术存在的不足，本申请的目的在于提供一种内置风扇的电子调速器。
为了实现上述目的，本申请采用如下技术方案：
一种内置风扇的电子调速器，它包括铝件、无框风扇和螺丝，所述无框风扇通过螺丝安装于铝件上，所述铝件包括底座和散热围栏，所述散热围栏位于底座的顶部，所述散热围栏的外侧壁开设有至少一个由若干个孔位组成的孔位结构区。
优选地，所述底座和散热围栏均为铝质材料结构体，且所述底座和散热围栏一体成型。
优选地，所述孔位结构区为一由若干个孔位组成的条形网状结构。
优选地，所述无框风扇包括风扇和定子座，所述定子座的中心形成中空圆柱体，所述风扇装设于中空圆柱体上，所述定子座的边缘形成锁紧开口，所述底座的顶部开设有螺丝孔位，所述螺丝穿过锁紧开口与螺 丝孔位连接。
优选地，所述锁紧开口呈环形阵列分布于定子座上。
优选地，所述风扇设置有塑胶扇叶。
优选地，所述散热围栏的边角开设有斜凹槽。
由于采用了上述方案，本申请通过铝件上的散热围栏，使得将热量快速传递，利用无框风扇的设计，同时在孔位结构区的配合下，有效的增加风扇的散热效果，实现出风风道畅通，为提升出风能力创造了结构条件，同时无框风扇沉入铝件中的设计，设计创意独特，造型新颖，而且避免了传统风扇散热一般、出风能力一般等问题，其结构简单紧凑，具有较强的新颖性和创造性，且有很强的实用价值和市场推广价值。
附图说明
一个或多个实施例通过与之对应的附图中的图片进行示例性说明，这些示例性说明并不构成对实施例的限定，附图中具有相同参考数字标号的元件表示为类似的元件，除非有特别申明，附图中的图不构成比例限制。

图2是本申请实施例的分解示意图；
图3是本申请实施例的铝件结构示意图；
图4是本申请实施例的定子座结构示意图；
图5是本申请实施例的风扇结构示意图。
具体实施方式
以下结合附图对本申请的实施例进行详细说明，但是本申请可以由权利要求限定和覆盖的多种不同方式实施。
如图1至图5所示，本实施例提供的一种内置风扇的电子调速器，它包括铝件10、无框风扇20和螺丝30，无框风扇20通过螺丝30安装于铝件10上，铝件10包括底座11和散热围栏12，散热围栏12位于底座11的顶部，散热围栏12的外侧壁开设有至少一个由若干个孔位组成的孔位结构区121。
基于此，本申请通过铝件10上的散热围栏12，使得将热量快速传递，利用无框风扇20的设计，同时在孔位结构区121的配合下，有效的增加风扇的散热效果，实现出风风道畅通，为提升出风能力创造了结 构条件，同时无框风扇沉入铝件中的设计，设计创意独特，造型新颖，而且避免了传统风扇散热一般、出风能力一般等问题，其结构简单紧凑，具有较强的新颖性和创造性，且有很强的实用价值和市场推广价值。
作为优选方案，底座11和散热围栏12均为铝质材料结构体，且底座11和散热围栏12一体成型；一体成型使得底座11和散热散热效果好；铝质材料导热性好，当然，底座11和散热围栏12材质不限于铝质材料，其他导热性好的也同样可以选用。
作为优选方案，孔位结构区121为一由若干个孔位组成的条形网状结构；能够解决散热问题，实现出风风道畅通，当然，本实例的条形网状结构，也可以采用蜂窝状孔洞等其他形状，以达到增加风扇的散热效果，实现出风风道畅通的目的。
为优化结构，无框风扇20包括风扇21和定子座22，定子座22的中心形成中空圆柱体221，风扇21装设于中空圆柱体221上，定子座22的边缘形成锁紧开口223，底座11的顶部开设有螺丝孔位111，螺丝30穿过锁紧开口223与螺丝孔位111连接；风扇21通过中空圆柱体221安装于定子座22上，螺丝30穿过锁紧开口223与螺丝孔位111连接，使得底座11与定子座22相互固定连接在一起，同时也能方便装配工人安装，提升生产效率。
为进一步优化结构，锁紧开口223呈环形阵列分布于定子座22上；使得在安装时受力均匀，可以开设三个锁紧开口223，使得在保证受力均匀的情况下，所要开设的锁紧开口223尽可能的少。
风扇21设置有塑胶扇叶212；风扇21侧壁设置有塑胶扇叶212。
为提升观赏性，散热围栏12的边角开设有斜凹槽122；斜凹槽122与孔位结构区121一起呈现出整个产品的整体性，不会显得突兀。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，
凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
