具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述，显然，所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施方式，都属于本申请保护的范围。
请一并参阅图1、图2和图3，图1是本申请实施例提供的充电桩1000的立体结构示意图；图2是图1所示充电桩1000在另一视角下的立体结构示意图；图3是图1所示充电桩1000的内部俯视结构示意图。
本申请实施例提供一种充电桩1000，该充电桩1000包括桩体100和充电组件200，充电 组件200设于桩体100内，以实现相应充电功能，桩体100对充电组件200起到封装及保护的作用。其中，桩体100包括风腔101、进风口102和出风口103，充电组件200容置于风腔101，进风口102和出风口103将风腔101与外界连通，空气可由进风口102进入风腔101，并经过充电组件200后由出风口103排出，从而将充电组件200产生的热量带出至外界，以降低充电组件200的温度。
可以理解的是，在本实施例中，进风口102、风腔101和出风口103的底端平齐，且在沿桩体100的高度方向上，上述三者的尺寸相同。在上述结构下，进风口102、风腔101和出风口103处于同一水平高度，且高度尺寸均相同，空气在依次经过进风口102、风腔101和出风口103时，空气的流经通道的截面在高度尺寸上保持一致，仅在横向尺寸上存在一定的变化，从而使得空气在流动时不会因风道高度尺寸的频繁变化而产生较大的局部压力损失，有效降低了充电桩1000的内部气流阻力。
一种实施例中，充电桩1000还包括电器组件500，电器组件500设于桩体100内，电器组件500与充电组件200相配合，以用于对待充电的车辆进行充电，在此不对电器组件500的结构进行具体的限定。
本申请实施例提供的充电桩1000，通过设置进风口102、风腔101和出风口103的底端齐平，且在沿桩体100的高度方向上，进风口102、风腔101和出风口103的尺寸相同，使得空气在充电桩1000内流动时，其流经通道的截面在高度尺寸上保持一致，空气在流动时不会因风道高度尺寸的频繁变化而产生较大的局部压力损失，从而使得充电桩1000的内部气流阻力得到有效降低，充电桩1000的流通风量增加，进而充电组件200的温度下降，提高了充电桩1000的充电效率。
请一并参阅图3至图6，图4是图1所示充电桩1000在另一视角下的立体结构示意图；图5是图4所示充电桩1000中的充电组件200的立体结构示意图；图6是图5所示充电组件200在另一视角下的立体结构示意图。
一种实施例中，充电组件200包括相对设置的第一开口201和第二开口202，第一开口201和第二开口202将充电组件200的内部与风腔101连通，自进风口102进入的空气经第一开口201进入充电组件200，并由第二开口202排出，且在沿桩体100的高度方向上，风腔101的尺寸大于或等于第一开口201的尺寸。可以理解的是，充电组件200在执行相应充电功能时，其内部发热严重，是主要的发热源，在本实施例中，充电组件200为贯通的结构，空气可通过第一开口201进入充电组件200的内部，再由第二开口202排出，以有效带出充电组件200的内部热量，从而达到较佳的散热效果。
还可以理解的是，当空气在充电组件200的内部进行流动以带走其内部的热量时，若空气在其内部各位置的流速不均匀，会导致充电组件200的内部各位置的散热效果不一致，且难以同时满足相应散热要求。而在本实施例中，沿桩体100的高度方向上，风腔101的尺寸大于或等于第一开口201的尺寸，使得风腔101内的空气能够均匀的覆盖第一开口201，从而由第一开口201进入充电组件200内部各位置的空气的流速相同且均匀，充电组件200的内部各位置的散热效果能够同时满足相应散热要求，进一步提高了充电桩1000的散热效果，使得充电桩1000的充电效率得到了有效提升。
请再次参阅图3，一种实施例中，桩体100内还设有隔板10，隔板10和充电组件200共同将风腔101分隔为进风风道1011和出风风道1012，进风风道1011连通进风口102和第一开口201，出风风道1012连通出风口103和第二开口202。可以理解的是，隔板10和充电组件200共同将桩体100内的风腔101分隔为多个相互连通的空间，如进风风道1011和出风风 道1012，从而在保持桩体100体积不变的同时，增加了桩体100内部空间的表面积，使得充电桩1000内部产生的噪音可在桩体100的内部空间中进行多次反射，每经一次反射吸收，声能逐渐衰减，以达到较佳的降噪效果，且充电桩1000仍可保持较小的体积，以降低成本。
其中，隔板10上和桩体100的内壁上均设有第一吸音件20，第一吸音件20用于吸收充电桩1000产生的噪音。可以理解的是，在充电桩1000内，充电组件200为主要的噪音源，而在本申请实施例中，充电组件200的内部仅通过第一开口201和第二开口202与外部连通，因此，充电组件200内部所产生的噪音仅能由第一开口201经进风风道1011传出至外界，或由第二开口202经出风风道1012传出至外界。在上述结构下，通过在隔板10和桩体100的内壁上设置第一吸音件20，使得进风风道1011和出风风道1012内覆盖有第一吸音件20，充电组件200内部产生的噪音在经过进风风道1011和出风风道1012时，会被第一吸音件20吸收，绝大部分噪音无法传出至外界，从而有效提高了充电桩1000的降噪效果。需要说明的是，第一吸音件20包括但不限于吸音棉，还可以为其他任意具备吸音功能的结构，在此不对第一吸音件20的结构进行具体的限定。
一种实施例中，位于进风风道1011内的第一吸音件20的吸音总面积大于等于进风口102的面积的4倍。可以理解的是，当进风风道1011内的第一吸音件20的吸音总面积较大，且第一吸音件20与进风口102的面积比大于或等于4时，第一吸音件20可对经进风风道1011传出的噪音进行有效吸收，根据声强理论计算，上述结构可以降低噪音至少7db，以使充电桩1000能够有效实现相应降噪要求。
一种实施例中，进风风道1011呈曲折结构，以使噪音在经过进风风道1011时会进行多次反射。可以理解的是，进风风道1011连通进风口102和第一开口201，当由隔板10和充电组件200分隔形成的进风风道1011呈曲折结构时，噪音在曲折的进风风道1011内进行传播的过程中会发生多次反射，每一次反射均会使得噪音的声能衰减，从而达到较佳的降噪效果。
请一并参阅图7和图8，图7是图2所示充电组件200中的进风组件300的立体结构示意图；图8是图7所示进风组件300的剖面示意图。
一种实施例中，在进风口102处还设有进风组件300，进风组件300包括固定件31和过滤件32，固定件31用于固定过滤件32，过滤件32覆盖进风口102，以用于过滤空气中的杂质。可以理解的是，进风组件300的存在，能够对将进入充电桩1000内部的空气进行有效过滤。其中，固定件31用于固定过滤件32，固定件31包括但不限于固定框体和压条，还可以为其他任意具备相应固定功能的结构，在此不对固定件31的种类进行具体的限定。同样的，过滤件32包括但不限于钢丝网和防尘棉，还可以为其他任意具备相应过滤功能的结构，在此不对过滤件32的种类进行具体的限定。
请一并参阅图9至图12，图9是图1所示充电桩1000在另一视角下的立体结构示意图；图10是图9所示充电桩1000中的出风组件400的立体结构示意图；图11是图10所示出风组件400在另一视角下的立体结构示意图；图12是图11所示出风组件400的剖面示意图。
一种实施例中，在出风口103处还设有出风组件400，出风组件400包括第一固定板41、第二吸音件42和多个风机43，在沿桩体100的高度方向，多个风机43并排且间隔设于第一固定板41上，以用于将风腔101内的空气抽出，且至少两个相邻的风机43之间设有第二吸音件42。可以理解的是，多个风机43的存在，可将风腔101内的空气抽出，从而使得空气在充电桩1000的内部进行快速流动，以达到相应的降温效果。第一固定板41用于固定多个风机43，且在沿桩体100的高度方向上，多个风机43并排且间隔设于第一固定板41上，以 实现多个风机43的均匀分布，从而使得风腔101内各位置的空气的流速相同，以达到均匀散热的目的。还可以理解的是，风机43同样是充电桩1000内部的主要噪音源之一，当多个风机43进行工作时，会产生噪音。因此，在至少两个相邻的风机43之间设置第二吸音件42，能够对多个风机43产生的噪音进行有效吸收，以实现相应降噪功能。
一种实施例中，出风组件400还包括第二固定板44，第二固定板44与第一固定板41相对且间隔设置，第二固定板44上开设有多个子出风口401，在沿桩体100的高度方向，多个子出风口401并排且间隔设置，且多个子出风口401与多个风机43相互错开。可以理解的是，在上述结构下，风腔101内的空气经多个风机43抽取后，由多个子出风口401排出至外界。并且，在沿桩体100的高度方向，多个子出风口401并排且间隔的开设于第二固定板44上，以实现多个子出风口401的均匀排布，从而风腔101内的空气可由多个子出风口401均匀的排出至外界，以达到均匀散热的目的。还可以理解的是，在本实施例中，多个子出风口401与多个风机43相互错开，从而风机43工作所产生的噪音不会直接从子出风口401传出，而是会在二者相错开的空间内进行多次反射后再由子出风口401传出，在一定程度上消耗了噪音的能量，达到了相应的降噪效果。
一种实施例中，出风组件400还包括多个第三吸音件45，每相邻两个子出风口401之间均设有一个第三吸音件45，且多个第三吸音件45和多个风机43一一正对设置。可以理解的是，由于多个子出风口401与多个风机43之间相互错开，因此，可在每相邻两个子出风口401之间均设置一个第三吸音件45，并使得多个第三吸音件45与多个风机43之间一一正对设置，从而第三吸音件45可对多个风机43产生的噪音进行进一步吸收，进一步提高了充电桩1000的降噪效果，使得充电桩1000的充电效率得到了有效提升。
一种实施例中，第二吸音件42和第三吸音件45的吸音总面积大于等于多个子出风口401的总面积的3.5倍。可以理解的是，当出风组件400中的第二吸音件42和第三吸音件45的吸音总面积较大，且二者与多个子出风口401的面积比大于或等于3.5时，第二吸音件42和第三吸音件45可对经风机43传出的噪音进行有效吸收，根据声强理论计算，上述结构可以降低噪音至少6.2db，以使充电桩1000能够有效实现相应降噪要求。需要说明的是，第二吸音件42和第三吸音件45包括但不限于吸音棉，还可以为其他任意具备吸音功能的结构，在此不对第二吸音件42和第三吸音件45的结构进行具体的限定。
以上所揭露的仅为本申请一种较佳实施例而已，当然不能以此来限定本申请之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本申请权利要求所作的等同变化，仍属于申请所涵盖的范围。
